What is the vacuum cleaner principle?

When the home is in a mess and the dust is flying all over the sky, there is a vacuum cleaner at this time, which can help people better clean and maintain the home life. Then talk about the vacuum cleaner, I don't know if you know what its principle is? Next, let's take a look at the principle of the vacuum cleaner. What are the precautions for vacuum cleaner purchase?

What is the principle of the vacuum cleaner?

Speaking of the vacuum cleaner, what is your impression of it? The vacuum cleaner is mainly composed of dusting, vacuuming and dust filtering. It usually includes a series commutator motor, a centrifugal fan, a dust filter (bag) and a vacuum attachment. Generally, the power of the vacuum cleaner is 400-1000 W or higher, and the power of the portable vacuum cleaner is usually 250 W or less.

What types of vacuum cleaners are available on the market? The vacuum cleaner can remove dust, mainly because its "head" is equipped with an electric blower. There is a wind impeller on the rotating shaft of the exhaust fan. After the power is applied, the suction timing generates a strong suction and pressure at a speed of 500 laps per second. Under the effect of suction and pressure, the air is discharged at a high speed, and the air at the front end of the fan is constantly ventilated. The air in the fan is compensated for, so that an instantaneous vacuum occurs inside the vacuum cleaner, and a negative pressure difference is formed with the external atmospheric pressure, and the dust-containing air is sucked under the effect of the pressure difference. After the air is purified by the filter, it is discharged from the tail of the body.

What are the main principles of the vacuum cleaner? The dust bag in the vacuum cleaner is full and the air circuit is blocked. Remove waste debris from the dust bag. The hose, nozzle, and dust bag interface are blocked by foreign objects. It should be checked whether the passages and micropores are blocked, and the foreign matter can be removed to make it clear. The connection between the hose, the brush holder and the extension tube is not good enough to form a leak. Check the connections and pick them up from the beginning. The connection between the center of the housing is not connected or the sealing ring is aging failure. Check the joints and check the seals and replace them if necessary.

Vacuum cleaner purchase tips

Vacuum cleaner purchase skill 1: The connection of each part of the vacuum cleaner should be strict, especially the intersection of the dust collecting part and the power part. The test method is: start the power switch, close to the joint by hand, if there is no feeling of air leakage, the tightness is good, otherwise it is poor, and the vacuum cleaner with poor sealing not only has poor vacuuming effect, but also consumes a large amount of electricity.

Vacuum cleaner purchase skill 2: The vacuum cleaner of the regular manufacturer is packed neatly, the manual, certificate of conformity and warranty certificate must be complete, the accessories are complete, the appearance is smooth, and the appearance is elegant. The electrical parameters on the nameplate of the appliance are complete (power supply voltage, power supply symbol, power frequency, power manufacturer or trademark, etc.). Now the horizontal vacuum cleaner, its power cord has the function of automatic rewinding. Try to pull out a section of the power cord and press the rewind button to check whether the action is sensitive and reliable.

Vacuum cleaner purchase skill three: vacuum cleaner is the motor drag the fan blade to generate a negative pressure. Therefore, when identifying the quality of the dust removal performance, turn on the power, close to the suction port by hand, there is a significant suction (into the box). The greater the suction, the better the vacuum or water absorption of the appliance. Otherwise, it is not.

As a household appliance that helps clean the home, vacuum cleaners have been loved by many families since their inception. In the purchase of vacuum cleaners, consumers also need to master the relevant purchasing skills, which can help you buy a vacuum cleaner that is more cost-effective and can help people clean and help.
