Step 806: the fan of the work station works to generate a pressure difference between the inside and the outside of the dust discharge opening pressing plate 30 on the dust box main body 10 to form air pressure as the driving force.

Step 808: the air pressure drives the two ash discharge hole pressing plates 30 to synchronously rotate with the intermediate rotating shaft 20 so as to synchronously open the two ash discharge holes 11.

In a preferred embodiment of this embodiment, a reset mechanism is disposed between the main body 10 and the intermediate shaft 20;

step 808 specifically comprises: the air pressure overcomes the reset force provided by the reset mechanism and drives the two ash discharge port pressing plates 30 and the middle rotating shaft 20 to synchronously rotate so as to synchronously open the two ash discharge ports 11;

the control method of the sweeping robot further comprises the following steps:

after the dust exhaust of the sweeping robot is completed, the reset force provided by the reset mechanism drives the two dust exhaust hole pressing plates 30 and the middle rotating shaft 20 to synchronously rotate so as to synchronously close the two dust exhaust holes 11.

In this embodiment the ash discharge opening pressing plate 30 is under the effect of drive power, because two the ash discharge opening pressing plate 30 sets up on same middle pivot 20, two promptly the ash discharge opening pressing plate 30 is coaxial to be arranged, like this drive power orders about two the ash discharge opening pressing plate 30 can synchronous rotation with middle pivot 20, realizes two the ash discharge opening 11 is opened in step, avoids opening an ash discharge opening 11 after, and the follow-up unable condition of opening or the very little condition of opening appears of second ash discharge opening 11 because of the reduction of pressure differential, two the ash discharge opening 11 is opened in step and can be ensured dust is followed two respectively in the dirt box main part 10 the ash discharge opening 11 discharges simultaneously for the discharge rate of dust in the dirt box main part 10, and then improves the discharge efficiency of dust in the dirt box main part 10.
