How does a vacuum cleaner work?

Vacuum cleaners are small household appliances that everyone is familiar with. Although they are compact and easy to use, do you know how they work? Don't underestimate it, there are complex internal structures and working principles under the simple appearance. Vacuum cleaners bring us a clean and hygienic space while saving time and effort, so they are loved by everyone. Below is what I have compiled about how a vacuum cleaner works. What is the working principle of a vacuum cleaner 1

The working principle of a vacuum cleaner - the structure of a vacuum cleaner

Before introducing the working principle of a vacuum cleaner, let us understand the structure of a vacuum cleaner. Only when the structure is clear can it be easier to understand. principle. Vacuum cleaners generally consist of three major structures: power unit, filter unit and accessories. The power part is of course the most important motor. Motors come in different sizes and categories. In addition, there is a device for adjusting the output power of the motor, referred to as a regulator; the filtration system is composed of filters, dust bags, etc.; the accessories department also It is just some additional accessories and humanized design to facilitate people's use, such as handles, hoses, etc.

The working principle of a vacuum cleaner

We have learned about the structure of a vacuum cleaner. Now let’s talk about the working principle of a vacuum cleaner. In fact, the working principle of a vacuum cleaner is not complicated. It mainly uses the principle of pressure. When the vacuum cleaner is working, the motor rotates at high speed, sucking away the air close to the ground, creating a vacuum-like environment. Due to the effect of atmospheric pressure, hair and other garbage on the ground are pushed into the vacuum cleaner by the external atmospheric pressure, so it can also be said to be a vacuum cleaner. Inhalation of waste. After inhaling the garbage, use the filter bag filter to filter the garbage out, so that the vacuum cleaner completes a working cycle.

This is a horizontal vacuum cleaner. As for the Haier brand, it goes without saying that Chinese people are very fond of it. clear. This Haier vacuum cleaner has an ultra-quiet working mode and is a true consumable-free vacuum cleaner. First of all, the purple appearance is very attractive. It adopts Haier's latest generation vortex air duct, which greatly improves the suction power. The unique double-side exhaust design can achieve deeper filtration and extend the life. But as everyone knows, Haier is not a company that specializes in vacuum cleaners.

JENO JN202-20L

This vacuum cleaner is a barrel-type vacuum cleaner. Its barrel is made of metal, which is very strong and durable. It can be used both dry and wet, and can absorb dry garbage as well as water and liquid pollutants. As for general household cleaning, the service life can be up to 10 years. Geno bucket vacuum cleaners are sold overseas. They are equipped with advanced German motors and are extremely cost-effective. However, this metal barrel is a little heavier and the appearance is not that gorgeous.

How about it? After reading this article, do you have a clear understanding of the working principle of vacuum cleaners and a better understanding of vacuum cleaners? At the same time, friends who want to buy a vacuum cleaner should pay attention. When buying a vacuum cleaner, you can make a specific decision based on your actual situation and do not blindly follow the trend. What is the working principle of a vacuum cleaner 2

Automatic vacuum cleaners have built-in smart chips that can automatically identify and judge the home environment, calculate walking paths, and automatically clean dust on the floor. Today we will take a look at the working principle of smart vacuum cleaners.

Working principle of smart vacuum cleaners

1. Smart vacuum cleaners use ultrasonic detection technology to detect obstacles by emitting ultrasonic pulses in the forward and downward directions and receiving corresponding returned sound wave pulses. judge.

2. Then it feeds back to the controller with the computer chip as the core, and based on the returned pulse signal, it judges and selects the corresponding control strategy.

3. The driver drives the forward and reverse steering and speed of the two drive wheel motors to realize the forward, backward and turning of the machine.

4. At the same time, the small vacuum cleaner carried inside the machine performs necessary vacuum cleaning on the passing ground.

The above information about the working principle of smart vacuum cleaners has been introduced here. Is there anything else unclear? I hope it will be helpful to everyone. What is the working principle of a vacuum cleaner 3

The various vacuum cleaners in the shopping mall all follow the same working principle: the motor drives the blades to rotate at high speed, forming a vacuum in the confined space, thereby inhaling Dust gets in.

In theory, any vacuum cleaner has a cleaning function that is unmatched by human power, but the cleaning capabilities do vary, mainly due to dust collection, filtration, appearance and even brand.

Knowledge points

From the perspective of dust collection and filtration methods, dust bag vacuum cleaners are convenient and bagless vacuum cleaners are environmentally friendly; cyclonic vacuum cleaners have less clogging and water filtration has the best effect.

From the appearance point of view, the horizontal vacuum cleaner is the most commonly used, the vertical type has less energy loss, the handheld type has a wide range of flexibility, and the cylinder type has a large capacity for wet and dry use.

Choose from brands. If you are not afraid of trouble or have a nanny at home, use K?rcher; if you do housework by yourself, if you have mysophobia or allergies, use Miele; if you are technically savvy, not short of money, have small animals, and are not virgins For seats, buy Dyson.

An advertisement for a certain brand of vacuum cleaner, "A powerful vacuum cleaner can do many things, such as hunting birds."

Which type of vacuum cleaner has strong suction capabilities? Analysis from the dust collection and filtration method

Today’s household vacuum cleaners are mainly divided into two types: dust bag type and dust bagless type. The dust bag type is cheaper and more convenient, while the dust bag type is more environmentally friendly and durable.

1. Dust bag vacuum cleaner

Dust collection and filtration are all solved by dust bags. Dust bags use the most traditional filter materials, paper and cloth. Paper bags are disposable, cheaper, and convenient to throw away after use, but they are not environmentally friendly, and their filtration efficiency is only 60%. The most commonly used fabric is SMS composite non-woven fabric, which is often used in surgical gowns and surgical caps. It has high efficiency in isolating bacteria, is breathable, impermeable to water and dust, and has a filtration effect of up to 80%.

Working principle diagram of the dust bag vacuum cleaner: it relies on the internal dust bag to filter the dusty air and accumulates the filtered dust directly in the bag.

This type of vacuum cleaner has two obvious shortcomings. One is that long-term use can easily block the ventilation holes of the dust bag, causing the suction rate to drop quickly and affecting the life of the motor; the other is that it requires constant cleaning. Later investment, such as regularly taking out the cloth dust bag to dump the dust, cleaning the cloth bag (at this time, it is easy to cause secondary pollution by flying dust, and the scene of cleaning is terrible), or constantly buying paper dust bags to replace.

Considering that directly using dust bags for filtration will make the machine too tiring, many brands have begun to improve. For example, the Miele S8 series is also equipped with Air Clean filter cotton and motor protection filter cotton.

2. Bagless vacuum cleaner

Compared with the basic dust bag type, the dust collection and filtration of the bagless type is relatively complicated, and is mainly divided into two types: cyclone and water filtration. .

1) Cyclone filtration

The cyclone type was first invented by Dyson. This design of first using a cyclone for separation and then dust collection and filtration can reduce clogging and make horizontal suction more durable and powerful. Filtering the air and then discharging it can also prevent secondary pollution.

However, it should be noted that not all vacuum cleaners with dust boxes can create cyclones to filter dust. Some dust boxes have a narrow space, and the airflow cannot form a cyclone inside, and can only be filtered by a filter. This is actually not much different from the dust bag type, except that the bag is replaced by a plastic box.

Working principle diagram of cyclonic vacuum cleaner: It uses the high-speed centrifugal force formed by the rotation of air in the dust collection bucket to separate dust gas. The dust falls into the dust bin due to gravity, and the separated air passes through the motor protection filter. and discharged after HEPA filtration.

Although replacing dust bags with plastic dust bins reduces the consumption of subsequent dust bags, it does not fundamentally solve the dust generated during dumping and the trouble of cleaning. Most dust bins are made of transparent resin material, so the unsightly hair and garbage inside can be clearly seen during cleaning. And not using a dust bag does not mean that there are no subsequent accessories consumed, and the cost of the HEPA filter still exists. Because the HEPA filter is a disposable product and cannot be cleaned thoroughly, the filtration effect will generally be much worse if it is a washable filter.

2) Water filtration

The filtration effect of water filtration vacuum cleaners is the best among the three. However, there are gains and losses. Cleaning the water filter type is also the most troublesome among the three. You need to drain the water every time you use it. You also need to clean the water tank after use, otherwise it will easily become moldy, smelly or even rusty. Being so difficult to serve does indeed require a diligent master.

Working principle diagram of water filter vacuum cleaner: using water as the filtering medium, dust and microorganisms are first dissolved and locked in the water, and then further filtered through the filter. The air exhausted in this way is often cleaner than the air inhaled, so there is no need to worry about secondary pollution.

In addition, using water as the medium places high requirements on the design of the product itself and the protection of the motor against water discharge. This is also the main reason why the quality of water filters on the market is uneven and the prices vary widely. If you don’t have a big budget, it’s recommended not to take risks. If you are a wealthy person, you can pay attention to Rainbow, which combines a vacuum cleaner, mite remover, and air purifier into one, which has a certain effect on asthma and dust mite allergies.

Doesn’t it matter what you look like? Appearance is actually one of the functions.

Don’t think that it doesn’t matter if you don’t have an appearance association. The appearance of a vacuum cleaner is also one of its functions. We divide them into the following categories based on the common models on the market:

1. Horizontal type

The horizontal type is the most common type in Asian families. It is said that in Asia Europe's market share is as high as 80%. The distinction between dust bags and non-dust bags was first based on horizontal vacuum cleaners. Its main advantages are: large dust holding capacity, large suction power, relatively cheap price, and easy storage.

Among foreign brands, the Miele S8 series is recommended for horizontal vacuum cleaners. It has excellent performance and low noise, but the price is higher and there are fewer shopping channels.

Miele S8 Series

Domestic brand Leike VC-T3519-3 is also good. It can be used for floors and carpets, and domestic after-sales service is also more convenient.

2. Vertical type

Simply speaking, it is an integrated product with body and suction head, suitable for large areas Carpet cleaning is more common in European and American markets, but it is also sold in the Chinese market. Compared with the horizontal type, there is no need to drag the fuselage when using it, and you don't even need to bend down when the height is suitable, which is more convenient and labor-saving; the straight-through vacuum pipe instead of the hose also reduces the loss of energy along the way, so the suction power is converted into suction power higher efficiency.

However, the shortcomings of the vertical type are also obvious. The integrated design will limit the dust holding capacity. Nowadays, the dust capacity on the market is less than 1L, so cleaning work is more frequent. What you need to pay attention to when purchasing is that because the vertical model is closer to the human body, the feeling of noise will be greater. For those who are more concerned about this aspect, we recommend the Vorwerk VK150 made in Germany, which has super strong suction and first-class noise resistance. The motor It has a lifespan of up to 15 years and is very durable.

3. Handheld

The lightweight handheld is very convenient to carry and use. Without the fetters of wires, it can move up to the sky and into the ground. It has a very good effect on the bed bottom, keyboard appliances, bed sheets and clothing in the car. However, due to size limitations, it is also frequently criticized for its low power and weak suction.

Among handheld mobile phones, Dyson, the originator, undoubtedly holds the dominant position. Many brands also borrow Dyson’s previous technology to continuously launch new products. The new DC62 is not only cool in appearance, cordless and lightweight, but its suction power is comparable to that of a wired vacuum cleaner.

4. Canister type

Canister vacuum cleaners were first used in business, mostly used by cleaning companies, hotels, and office buildings. However, in recent years Also began to enter ordinary families. It is characterized by large capacity and can be used both wet and dry. If you have pets at home with poor hygiene habits, you can choose a canister vacuum cleaner to handle mixed waste in one go. However, compared to other types, there are not many brands of canister vacuum cleaners to choose from, one of the more famous ones is K?rcher from Germany.

5. Sweeping robot

The biggest difference between robots and vacuum cleaners is their intelligence and power. It can be used all over the home with one-click operation without manual operation, meeting basic daily dust removal needs. Therefore, it is very popular among young white-collar workers. However, in terms of power and suction, it is naturally at a low level and cannot complete high-level cleaning like a vacuum cleaner, and its range of activities is limited to the ground.

Therefore, if you live in places with strong winds and sand such as Beijing and Lanzhou, or have high requirements for home cleanliness, it is recommended to give priority to a vacuum cleaner; if you have a sufficient budget, you can buy one as a supplement to daily cleaning.

Brand control is not unreasonable: imported products are selected from Germany and the UK, and there are also good domestic products

The industry threshold of the vacuum cleaner itself is not high, as long as it can form negative pressure in the body. It can meet the basic requirements of vacuuming, so there are endless brands on the market, and the prices are getting lower and lower. However, the gap between these entry-level products and high-end products is very obvious, both in terms of technological content and production process.

In terms of foreign brands, traditional home appliance manufacturers that are well-known to Chinese people, such as Philips, Electrolux, Panasonic, etc., have always had good sales and their performance is quite satisfactory. However, when it comes to recommendations, as a German motor brainiac Naturally, I still recommend Vorwerk and Miele. They suppress noise very well under the premise of strong suction, and the motors that can last for ten years are really my favorite. The other is Dyson, the old British brand, which is unrivaled in terms of styling and innovation capabilities. The core technologies of many mid-to-high-end products are borrowed from Dyson, and the performance is naturally no problem.

In addition to higher technological content, the advantages of foreign brands are that their product-related data are also trustworthy. The rated power, suction power, dust collection efficiency and other data provided in the manual are relatively reliable, and the difference from actual use can basically be controlled at 10%, so you can rest assured when purchasing for reference. However, the biggest disadvantage is that the price is relatively high. If you do not purchase it through official channels, the domestic warranty is also a headache.

If you prefer domestic brands, there are many high-quality choices. Now my country's foreign trade export volume of vacuum cleaners has accounted for a large part of the total number of global vacuum cleaners, and its production experience has been accumulated enough. There are also some companies that OEM for big brands all year round and have mastered certain technologies, so the overall gap with foreign brands in terms of quality and functionality is gradually narrowing.

Some domestic brands may not be very well-known in China but sell well in the international market. For example, Lake Electric has cooperated with large companies such as Electrolux. It is said that one of every six vacuum cleaners in the world is There is one from Lake. There are many choices of mid-range and high-end products, and the product quality and after-sales service are also trustworthy.

Cat people say: Technology makes cat life better!

Vacuum cleaners always shock me that I live in such a dirty environment every day. If you believe this, you must also own a suitable vacuum cleaner. What is the working principle of a vacuum cleaner 4

The working principle of a vacuum cleaner

The working principle of a vacuum cleaner is that the vacuum cleaner motor rotates at a high speed, sucking in air from the suction port, causing the dust box to generate a certain vacuum and dust. It enters the dust filter bag in the dust box through the floor brush, nozzle, handle, hose and main suction pipe. The dust is left in the dust filter bag. The filtered air enters the motor through a layer of filter. This layer of filter is to prevent the dust bag The cracked dust is sucked into a protective barrier of the motor, and the air entering the motor flows out through the motor. Because the carbon brushes are constantly worn during the operation of the motor, another filter is added before flowing out of the vacuum cleaner.

The finer the filter material, the cleaner the air can be filtered into the vacuum cleaner, but the worse the air permeability, which affects the air volume sucked by the motor and reduces the efficiency of the vacuum cleaner. But for users, comfort and cleanliness are the main thing.

Its air permeability is low, so it is made into a wavy shape to increase the breathable area. Some of this filter material can be cleaned repeatedly. Any filter material has a "life", that is, after long-term use, the micropores of the filter material have been blocked by small particles of dust. Therefore, paper dust bags are ideal because they are disposable and hygienic and convenient. After cleaning, the fibers of the cloth dust filter bag will become hardened, affecting the filtration and breathability effects. SMS three-layer composite filter material is washable, but has slightly lower air permeability.

How to use

1. Please open the dust collector and check whether the dust filter bag is in good condition.

2. Plug in the power and turn on the power switch.

3． Please choose various accessories according to different needs.

Cleaning and replacing parts

1. Open the dust collector

2. Take out the dust filter bag

3. Throw away the dust

4. Rinse

5. Dry

6. Install the dust filter bag and bag dust cover

Precautions for use

1. Before using the vacuum cleaner, check whether the fuse of the power supply can carry the current for starting and working of the vacuum cleaner. (General product manuals have instructions in this regard.)

2. Turn off the power switch of the vacuum cleaner, insert the power plug into the car cigarette lighter socket, start the car first, and then turn on the power switch of the vacuum cleaner to start operation. .

3. When the dust reaches a certain level or needs to be cleaned after use, press the clip on the dust cover to open the dust cover and remove the dirt.

　5. Working principle

Working principle of the vacuum cleaner: Through the high-speed rotation of the motor, a vacuum is formed in the main unit, and the resulting high-speed airflow is used to suck in garbage from the suction port. The key point is what is the working principle of "suction" vacuum cleaner 5

1. The vacuum cleaner uses the high-speed rotation of the motor to form a vacuum in the main unit, and uses the resulting high-speed airflow to suck in garbage from the suction port. . At this time, the speed of the airflow is as high as 240 rpm. When pests such as lice enter the main unit, they will die due to high-speed collision with the inner wall of the vacuum tube.

2. The garbage sucked into the vacuum cleaner is accumulated in the bag machine, and the air purified by the filter is discharged from the vacuum cleaner while cooling the motor. The motor is the heart of a vacuum cleaner, and its performance can directly affect the reliability of the vacuum cleaner.

3. In addition, the motor used in the vacuum cleaner rotates between 20,000 and 40,000 revolutions per minute. For example, the motor of an electric fan has a rotation speed of about 1800 to 3600 revolutions per minute. This shows how high the rotation speed of the vacuum cleaner motor is.

4. The resultant force of wind force and vacuum force generated by the vacuum cleaner, these two factors have opposite characteristics. In other words, when the wind force is strong, the vacuum force becomes weak, and when the vacuum force is strong, the wind force becomes weak. The maximum value of the resultant force of the two is the "suction power" that represents the capabilities of the vacuum cleaner. The suction power is expressed in watts (W).

Dust suction electrostatic precipitator contains gas containing dust particles. When the high-voltage electric field formed between the cathode wire connected to the high-voltage DC power supply and the grounded anode plate passes, corona discharge and gas will occur at the cathode. Be ionized. At this time, the negatively charged gas ions move toward the sun plate under the action of the electric field force, and collide with the dust particles during the movement, causing the dust particles to be negatively charged. Under the action of the electric field force, the charged dust particles It also moves towards the anode. After reaching the anode, it releases the electrons it carries, and the dust particles are deposited on the anode plate, and the purified gas is discharged out of the dust filter. How does a vacuum cleaner work? 6

What is a vacuum cleaner?

Electric vacuum cleaners have a history of 100 years and have become an indispensable household equipment for many people. , the reason is obvious. Current controls the operation of the motor. There is a fan attached to the motor, and the fan blades are angled like an airplane propeller. When the fan blades rotate, they push air all the way to the exhaust port. As air particles are pushed forward, the particle density in front of the fan increases and the air pressure increases accordingly, while the particle density behind the fan decreases. The pressure drop created behind the fan is similar to the pressure drop created in the straw when you sip a drink. The pressure behind the fan is lower than the pressure outside the vacuum, which is the ambient air pressure. This creates suction inside the vacuum cleaner, a partial vacuum.

Principles of vacuum cleaners

The main components of modern vacuum cleaners are vacuum pumps, dust bags, hoses and various nozzle tubes of different shapes. There is an electric exhaust fan inside the machine, which runs at high speed after being powered on, creating an instant vacuum inside the vacuum cleaner. The internal air pressure is much lower than the external air pressure. Under the action of this air pressure difference, dust and dirt enter the vacuum cleaner barrel along with the air flow. After being filtered by the dust bag, the dirt remains in the dust bag, and the purified air escapes back into the room through the motor, cooling the motor and purifying the air.

1. Principle of vacuuming. The fan impeller of the vacuum cleaner is driven by the motor at high speed, and the air in the impeller is discharged from the fan at high speed. At the same time, the air in the dust suction part is continuously replenished by the fan. This can create a higher pressure difference with the outside world. The dust and dirt from the suction nozzle are sucked into the suction part along with the air, and leak through the leaker, collecting the dust and dirt into the dust cylinder.

2. Original vacuum cleaner. All vacuum cleaners come with an assembled brush head for cleaning floors and carpets. Suction vacuum cleaners also come with a series of cleaning brushes and nozzles for cleaning corners, curtains, sofas and crevices.

3. Hose: All suction vacuum cleaners are equipped with hard hoses, which are used to connect flexible hoses and accessories for cleaning.

4. Electric brush: The cleaning head of an internal vacuum cleaner is a special accessory for hybrid vacuum cleaners.

5. Round brush head: It also has a smaller suction nozzle and can rotate 360 ??degrees, which is convenient for cleaning furniture, fine mesh fabrics, etc.

6. Flat nozzle: Also known as the gap nozzle, it is a slender, flat, hard nozzle. Especially suitable for cleaning walls, radiant heaters, corners and shallow and narrow places.

7. Dust sweeping brush: Made of long and soft bristles, suitable for cleaning curtains, walls, etc.

The above introduces information about what a vacuum cleaner is and the principle of a vacuum cleaner. I believe everyone has a certain understanding and is familiar with the use of a vacuum cleaner. It can not only clean the sanitation, but also clean the curtain box. Walls, etc. are good helpers for our furniture.
