Generally, the brushing and vacuum modes are adopted, and the ground sundries are firstly absorbed into the garbage storage box of the ground, so that the function of cleaning the ground is completed. Generally, robots that perform cleaning, dust collection, and floor scrubbing work are also collectively referred to as floor cleaning robots. Along with the development of technology, in order to reduce the frequency of cleaning the dust box inside the robot by a user, the current sweeping robot comprises a sweeping machine body and a base station, wherein the base station is provided with a dust box or a dust bag with large capacity, and garbage in the dust box of the sweeping machine body can be sucked into the dust box or the dust bag of the base station after the sweeping machine body is cleaned.

Currently, when a floor sweeping robot with a base station is used in the market, a dust collection opening dust baffle plate in a dust collection box is opened and closed by the suction force of the base station or driven by a motor. There are the following problems: the dust collection opening dust baffle plate which opens and closes the product by the suction force of the base station is free to rotate and has no structure to control the opening and closing size, so that the wind direction in the dust box can not be effectively controlled; the motor and the circuit are added to drive the opening and closing structure by the motor, so that the cost is high; because the wind direction in the dust box can not be effectively controlled, the garbage at the bottom of the dust box can not be sucked away when the back-suction dust collection is carried out, and the dust collection efficiency is low.
