The working principle of the dust removing device with double functions of upper and lower sides;

when the air purifier works normally, the filter screen 25 is positioned at the lowest end under the action of the pressure spring, so that dust is removed from air entering from the air inlet pipe 13, and clean air flows out of the air outlet pipe 14;

after hours of work, a lot of dust is accumulated on the filter screen 25, then the rotating motor 21 rotates intermittently to drive the central supporting rod 23 and the rotating central rod 22 to rotate, the gas is sprayed from the gas spraying holes 2600 of the upper blowing seat 26, and the filter screen 25 is wiped by the bristles 271, so that the dust removal effect is good through double effects;

simultaneously under the effect of balancing weight 24's centrifugal force, central support rod 23 rises and drives the filter screen 25 and rise, and the pressure spring is compressed by advancing steps, and when the rotating electrical machines 21 stopped rotating, the pressure release of pressure spring drove the filter screen 25 and descends, because the rotating electrical machines 21 intermittent type is rotatory, and filter screen 25 intermittent type goes up and down, leads to the shake of filter screen 25 like this, and dust removal effect is better.

The above description is only a preferred embodiment of the present invention, and for those skilled in the art, the present invention should not be limited by the description herein, since various changes and modifications can be made in the details of the embodiment and the application range according to the spirit of the present invention.
