Principle of pneumatic vacuum cleaner

The working principle of the vacuum cleaner is that the motor of the vacuum cleaner rotates at high speed, and air is sucked from the suction port, so that a certain vacuum is generated in the dust collection box. Dust enters the dust bag in the dust box through the floor brush, the connecting pipe, the handle, the hose and the main suction pipe. Dust stays in the dust bag, and the filtered air enters the motor through the filter, which is a protective barrier to prevent the dust bag from breaking and the dust from being sucked into the motor.

Air entering the motor flows out through the motor. Because the carbon brush is constantly worn during the operation of the motor, a filter is added before it flows out of the vacuum cleaner.
