When the mite removing device 100 stops working, the air door 33 at the dust collecting port 3171 moves from the open position to the closed position again under the action of the elastic force of the spring, so that the dust collecting port 3171 is closed, and the dust in the dust collecting chamber 316 is prevented from reversely flowing into the cyclone separating chamber 315 and flowing out from the suction port 12 of the mite removing device.
The damper 33 provided at the dust collection port 3171 functions as a one-way valve, and prevents dust in the dust collection chamber 316 from reversely flowing into the cyclone separation chamber 315 and out of the suction port 12 of the mite removal device 100 after the mite removal device 100 is powered off and stops working. The dust collecting device 30 of the present utility model has a better dust collecting effect than the prior art. Accordingly, the mite removing device 100 having the dust collecting device 30 has a better cleaning effect.
