principle of operation
The working principle of the vacuum cleaner is that the motor of the vacuum cleaner rotates at a high speed, and air is sucked from the suction port, so that the dust box generates a certain degree of vacuum. Dust enters the dust bag in the dust box through the floor brush, suction nozzle, handle, hose and main suction pipe, and the dust remains in the dust bag. The filtered air enters the motor through a filter screen, which is a protective barrier to prevent the dust bag from breaking and the dust from being sucked into the motor. The air entering the motor flows out through the motor, so it flows out because the carbon brush is constantly worn during the operation of the motor.
The finer the filter material, the cleaner the air can be filtered, but the worse the air permeability, which affects the air intake of the motor and reduces the efficiency of the vacuum cleaner. But for users, comfort and cleanliness are the main things.
Its air permeability is low, so it is wavy to increase the air permeability area. Some of these filter materials can be washed repeatedly. Any filter material has a "lifetime", that is, the micropores of the filter material have been blocked by fine dust particles after long-term use. Therefore, the paper dust bag ratio
Ideal, disposable after use, sanitary and convenient. After bag dust removal, the fiber will become hard, which will affect the filtration effect and ventilation effect. SMS three-layer composite filter material is washable, but its air permeability is slightly lower.
