How to choose a household vacuum cleaner Tips: Choose the most suitable vacuum cleaner according to the carpet type.

Vacuum cleaners can be divided into vertical, horizontal and portable according to their structures. The working principle of vacuum cleaner is that the motor drives the blades to rotate at high speed, which generates negative pressure in the sealed shell and sucks dust. 20 12 September, the output of domestic vacuum cleaners in China was 7.405 million. Now the air quality is declining day by day, and people have higher requirements for indoor environment. As a conventional cleaning tool, vacuum cleaner is used more and more frequently. Pay great attention to how to choose a household vacuum cleaner. It is necessary to master some selection methods, because it can make better choices. Here we have a brief understanding of how to buy a household vacuum cleaner and what skills it has.

First, the classification of vacuum cleaners

(1) classified by appearance: horizontal vacuum cleaner, vertical vacuum cleaner, portable vacuum cleaner and intelligent vacuum cleaner.

1. Horizontal

Vacuum cleaners are common in Asian and European markets, accounting for more than 80% of the whole market. They are characterized by compact appearance and convenient storage. Horizontal vacuum cleaners are also divided into "dust box vacuum cleaners" and "dust bag vacuum cleaners"

2. Vertical

American market is more common, suitable for large-scale carpet cleaning.

3. Handheld type

Small size, very convenient to carry and use, mainly used for car cleaning, keyboards, electrical appliances and other good results. The disadvantage is that the power is small and the suction is not strong enough.

4. Smart vacuum cleaner

Automatic cleaning of dust on the floor, automatic cleaning of hair and debris. High-end vacuum cleaner can automatically clean and charge, with low noise and small size, and can easily enter places that traditional vacuum cleaners can't reach.

(2) Classification by function: dry vacuum cleaner and dry-wet vacuum cleaner.

1. Dry vacuum cleaner

Compared with water-based vacuum cleaners, dust bags and dust cups are both dry vacuum cleaners.

2. Dry and wet vacuum cleaner

A water filtering vacuum cleaner, which uses water as the medium to deposit dust and fine garbage in a dust collecting cup; When the dust cup is not filled with water, it can be used as a dry cleaning machine.

(3) According to the filtration mode: dust bag (paper bag and cloth bag), dust cup (dust-free bag), dust cup and dust bag in one, and water filtration.

1. Dust bag vacuum cleaner

Dust and garbage are filtered through the dust bag in the machine. Generally speaking, the advantage of using a dust bag as a filter screen is that it is easy to clean and does not need to be cleaned every day. The disadvantage is that the dust bag needs to be replaced. In foreign countries, it is strongly recommended to use dust bags and disposable paper bags because it is more convenient.

2. Dust cup filtration

Dust cup filtration is to separate garbage and gas through the vacuum airflow rotated by the motor at high speed, and then purify the air through HEPA and other filtering materials to avoid secondary pollution. The advantage is that the dust bag does not need to be replaced frequently; The disadvantage is that it needs cleaning after vacuuming. Dust cup filtration is the main filtration method of vacuum cleaner. Most vacuum cleaners use dust cup filtration, which is also an upgrade of dust bag filtration. It also has the advantage of no consumables and avoids the second investment of funds.

3. The dust cup and the dust bag are combined into one.

In short, the above two methods are combined into one. Environmental protection cloth dust bag/disposable paper bag is more suitable for new house decoration. It is usually cleaned and used. Finish the housework, don't clean it, just throw it away. Dust cup design, lifelong consumables, suitable for daily small cleaning, can be used repeatedly.

4. Water filtration

Taking water as the filter medium, dust and microorganisms are locked in the water, and further filtering makes the discharged tail gas cleaner than the inhaled air. There is no doubt that the filtering effect of water is both wet and dry, and it can suck conventional broken glass, nail metal, muddy rice residue, sauces, drinks and tea leaves, decoration ash and so on. This is beyond the power of ordinary vacuum cleaners. The only disadvantage is that water needs to be drained every time, and there is a cleaning step after use.

Working principle of vacuum cleaner

. A vacuum cleaner generally consists of a power unit, a filter unit and accessories. The power part is of course the most important motor. There are different models, sizes and classifications of motors, and there are also devices to adjust the output power of motors, which are called regulators. The filtration system consists of filter screen, dust bag, etc. The accessories department is just some redundant accessories and humanized design, which is convenient for people to use, such as handles, hoses and so on.

Working principle of vacuum cleaner

The structure of the vacuum cleaner has been understood above. Now let's talk about the working principle of vacuum cleaner. In fact, the working principle of vacuum cleaner is not complicated, mainly using the pressure principle. When the vacuum cleaner works, the motor rotates at a high speed, which sucks the air close to the ground, forming a vacuum-like environment. Due to the atmospheric pressure, the garbage such as hair on the ground is pushed into the vacuum cleaner by the external atmospheric pressure, so it can also be said that the vacuum cleaner sucks garbage. After inhaling the garbage, the garbage is filtered by the filter bag filter, and the vacuum cleaner completes a working cycle.

How to choose a vacuum cleaner

Pay attention to 1 when buying vacuum cleaners. Look at the voltage of the vacuum cleaner

The standard rated voltage of vacuum cleaner is 220 volts and 500 hertz. Power connection of standard vacuum cleaner.

Pay attention to buying vacuum cleaner 2. Look at the sealing performance of the vacuum cleaner.

The connection part of the vacuum cleaner should be tight, and there is no feeling when the hand is close to the connection part, which shows that the vacuum cleaner with good sealing performance has good suction effect. Otherwise, the dust collection effect is poor and the power consumption is high.

Pay attention to the choice of vacuum cleaner 3. Look at the flexibility of the vacuum cleaner.

See if the vacuum cleaner has automatic rewinding function, and test whether its action is flexible and reliable. This is more convenient and labor-saving to use.

Pay attention to the purchase of vacuum cleaner 4. Look at the parameters of vacuum cleaner products.

Understand the specifications of vacuum cleaner, including capacity and power. Generally, when choosing a vacuum cleaner, it is best to combine the capacitance and function of the product with the actual needs. In the choice of shell, the plastic cylinder shell depends on whether the connecting part is fastened; The metal cylinder depends on whether the paint is uniform or not.

Pay attention to the choice of vacuum cleaner 5. Listen to the vacuum cleaner.

Generally, in the process of use, the smaller the sound of the whole machine, the better.

Pay attention to the purchase of vacuum cleaner 6. Look at the overall performance of the vacuum cleaner.

The shell should be bright; The filter screen has a double-layer net with large mesh and fine mesh; The starting speed of good quality products should not exceed 1 s; Small amplitude and low noise; After power failure, the deceleration time before parking should be more than 5 seconds, and the parking process should be smooth.
