The working principle of the vacuum cleaner is that the vacuum cleaner motor rotates at a high speed, and the air is sucked from the suction port to generate a certain vacuum. The dust passes through the ground brush, the nozzle, the handle, the hose, and the main suction pipe to enter the dust filter bag in the dust box, and the dust is left in the dust. In the dust filter bag, the filtered air enters the motor through a layer of filter. This filter is a protective barrier that prevents the dust bag from damaging the dust and sucks into the motor. The air entering the motor flows out through the motor, due to the continuous carbon brush in the motor running. Wear, so add a filter before flowing out of the vacuum cleaner.
The finer the filter material, the cleaner the air, but the worse the air permeability, which affects the air volume drawn by the motor and reduces the efficiency of the vacuum cleaner. But for the user, comfort and cleanliness are the mainstay.
Haipa is a foreign name. It is a high-efficiency filter that blocks very little dust and has an efficiency of 99.97%. It has a low air permeability and is therefore undulated to increase the air permeability. Some of this filter material can also be washed repeatedly. Any filter material has a "life", that is, the micropores of the filter material have been blocked by small particles of dust after long-term use. Therefore, paper dust bags are ideal, disposable, safe and convenient. After the cloth filter bag is cleaned, the fiber will be knotted, which affects the filtering effect and the ventilation effect. The SMS three-layer composite filter material is washable but has a slightly lower air permeability.
