The vacuum cleaner is mainly composed car shock absorber manufacturers of three parts: dust collection, dust removal and dust filter, generally including series excitation rectifier motor, centrifugal fan, dust filter (bag) and dust removal accessories. The power is 400-1000W or more, and the power of the portable vacuum cleaner is generally 250W and the following. The vacuum cleaner can remove dust, mainly because the small vacuum cleaner motor "head" is equipped with an electric extractor. There is a wind impeller on the rotating shaft of the suction fan. When powered on, the suction fan generates strong suction and pressure at a speed of 500 revolutions per second. Under the action of suction and pressure, the air is discharged at a high speed, and part of the air removed from the front end of the fan continuously replenishes the air in the fan, resulting in a negative pressure difference between the instantaneous vacuum inside the vacuum cleaner and the external atmospheric pressure. Under the influence of this pressure difference, dust-laden air is sucked in. Dust blankets or floors brush dust and other sundries, long pipes, elbows, hoses, and hose joints enter the dust filter bag, and dust and other sundries remain in the dust filter bag. After being purified by the filter, the air is discharged from the tail of the human body.

Other features of the vacuum cleaner:

1. It is used when collecting items.

When the seasons change, quilts and other items are collected because they take up a lot of storage space and are not stored properly. If you put them in a custom-made plastic sealed bag, and then use a brushless vacuum cleaner motor to suck the air out of the bag and seal it tightly, it will not only save storage space, but also not easy to get damp and moldy.

2. Find subtle objects.

In household life, it is inevitable to accidentally drop small items such as buttons, pills, bottle stoppers, sewing needles, etc., which can be easily found by relying on a vacuum cleaner. When in use, you can first wrap the suction port of the vacuum cleaner with a layer of gauze, and then select the appropriate wind speed according to the size of the item, then turn on the power, and use the suction port to roll back and forth around the falling objects, the falling items will soon be sucked into the gauze. superior.

3. Clean up electrical appliances.

Using the vacuum cleaner can also carry out daily maintenance on electrical appliances such as TVs, DVD players, computers, keyboards, speakers, air conditioners, etc., and remove dust inside and outside the large vacuum cleaner motors. When removing dust, first pull out the power plug of the electrical appliance, open and disassemble the electrical appliance casing according to the instructions, insert a suitable shape straw into the electrical appliance to remove dust, then use a hair dryer to remove moisture, and finally install the casing to return to normal.
