Internal structure and principle of vacuum cleaner

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, the suction nozzle, the handle, the hose and the main suction pipe, and the dust will remain in the dust bag, and the filtered air enters the motor through a layer of filter sheets.

This layer of filter screen is a protective barrier to prevent the dust bag from breaking and 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.
