The air flow of the air inlet 111 can flow in four directions in the dust box body 1, and cyclone is not generated due to the baffle plate 3, thereby improving dust collection efficiency.

Further, a lid is provided in the dust collecting chamber, the lid covers the air inlet 111, and the lid receives the elastic force of the ventilation structure 2 to seal the air inlet 111. When dust collection is carried out, the cover body is pressed on the inner surface of the dust pouring cover 11, and dust in the dust box body 1 is prevented from leaking when the dust box does not work.

Further, the ventilation structure 2 includes a bracket 22, and an elastic member is disposed on the bracket 22, and the elastic member enables the cover to open or close the air inlet 111. In the embodiment of the present invention, the air inlet 111 is a square through hole, the cover is a square plate structure, the bracket 22 is a square bracket, and the shapes of the bracket 22 and the cover are matched. Of course, the direction of the air inlet 111 may also be set to be circular, rhombic, etc., and is not limited in particular, and the shape of the air inlet 111 changes, and the shape of the bracket 22 and the cover also changes accordingly. The embodiments of the present invention are described only in the form of a square as a preferred embodiment.

Further, the bracket 22 includes a bracket body, and the bracket body encloses a frame formed smaller than the square through hole formed by the air inlet 111, so that the frame of the bracket body moves in the square through hole. The outer wall of the bracket body is provided with a buckle 221, and the buckle 221 is buckled with the dust pouring cover 11 at the air inlet 111, so that the bracket body is fixed on the dust pouring cover 11.

Further, the support body is provided with a connecting plate, the connecting plate is provided with a guide hole, and the elastic part is abutted to the bottom surface of the cover plate 21 through the guide hole, so that the elastic part stretches and retracts to change the distance between the cover plate 21 and the support 22, and the cover plate 21 opens or closes the air inlet 111.

Preferably, the connecting plates include two connecting plates, and the two connecting plates are perpendicular to each other and arranged on the bottom surface of the bracket body, so that the bracket body and the two connecting plates form a plurality of air inlet channels. Two guide holes are formed in the connecting plate, and of course, the number of the guide holes is not specifically limited, and only two guide holes are used as preferred embodiments for description, and other embodiments are also within the protection scope of the present invention.

Further, the elastic component comprises a screw rod 23, a spring 24 is sleeved on the outer wall of the screw rod 23, the spring 24 is arranged between the head of the screw rod 23 and the connecting plate, and the rod part of the screw rod 23 penetrates through the guide hole and abuts against the bottom surface of the cover plate 21. The bottom surface of the cover plate 21 is provided with an assembly groove, and the rod part of the screw 23 is in inserted fit with the assembly groove.

The shutter 3 is provided with a rotation shaft 31, and the shutter 3 and the rotation shaft 31 are connected by a torsion spring 32 to rotate the shutter 3 to open or close the air outlet 112.

The invention also discloses a cleaning robot, which comprises a workstation 4, wherein the dust box assembly is arranged on the workstation 4.

According to the dust box assembly provided by the invention, when the dust box body 1 is filled with dust, external air flow enters from the air inlet 111, the air flow pressure props against the cover body, the air flow pressure provides an upward force for the cover body, the screw 23 is penetrated with the spring 24 and is fixed on the cover body through the guide hole on the bracket 22 of the air inlet valve, when the pressure applied on the cover body is larger than the elastic force of the spring 24, the cover body and the screw 23 move upwards together to compress the spring 24, the cover body is separated from the inner wall of the dust pouring cover 11, and the ventilation structure 2 is in an open state; when the airflow disappears, the gas pressure acting on the cover disappears, the spring 24 restores to the original state, and the cover is pressed on the inner wall of the air inlet 111 of the dust pouring cover 11; when the cover body is in an open state, the air flow enters the dust box body 1 from four side surfaces of the ventilation structure 2, and then the air flow in four directions flows to the air outlet 112; while the external air flow enters the air inlet 111, the baffle 3 of the air outlet 112 is sucked away against the pressure of the spring 24 by the external suction force, which sucks out the dust in the dust box body 1 and the air flow entering from the air inlet 111.

Furthermore, as the spring 24 is subjected to the return elastic force during assembly, the elastic force acts on the screw 23, the elastic force acts on the cover body through the screw 23, the cover body is pressed on the inner surface of the dust pouring cover 11, and the dust in the dust box body 1 is prevented from leaking when not in work; when the air current enters from the air inlet 111, the air current pressure acts on the cover body, the cover body compresses the spring 24 through the screw 23 fixed on the cover body, when the air current pressure is larger than the elastic force of the spring 24, the spring 24 is compressed, the cover body moves upwards, the cover body is separated from the contact with the inner surface of the dust pouring cover 11, and the air current enters the dust box body 1 from the periphery of the cover body; the air inlet 111 is fixed in the shaft hole of the air outlet 112 by penetrating the rotating shaft through the spring 24 and the baffle 3, and the baffle 3 is tightly pressed at the air outlet 112 by the elasticity of the spring 24, so that dust is prevented from falling off when the device does not work.

The air flow of the air inlet 111 provided by the dust box component and the cleaning robot of the invention can flow to a plurality of directions in the dust box body 1, and cyclone can not be generated due to the baffle plate 3, thereby improving the dust collection efficiency.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
