It should be noted that, there are various ways to open the switch door 45, for example, when the switch door 45 is a rolling door structure, the switch door 45 can be rotated under the action of a motor to complete rolling or releasing; if the switch door 45 is of a plate structure, the switch door 45 can be rotated under the action of a motor to open and close the switch door 45, and the switch door 45 is more opened and closed correspondingly, which is not shown here.

In some embodiments of the present invention, the opening and closing door 45 is opened or closed by a force generated when air flows, and in particular, referring to fig. 1 and 3, the opening and closing door 45 includes a door body 451, the door body 451 is rotatably installed in the dust collecting channel 13, and the door body 451 is rotated by flowing air to open or close the dust collecting channel 13.

Specifically, when the cleaning robot 100 performs a cleaning action on the floor, the suction device 25 of the cleaning robot 100 works, at this time, air is discharged into the environment after passing through the installation cavity 11, the dust collection cavity 12 and the suction device 25, and is also discharged into the environment after passing through the dust collection channel 13, the dust collection cavity 12 and the suction device 25, at this time, the air in the dust collection channel 13 flows from the dust collection channel 13 to the dust collection cavity 12, so that the door 451 positioned in the dust collection channel 13 closes the dust collection channel 13 under the action of flowing air.

When the cleaning robot 100 is in butt joint with the cleaning base station 200 and performs dust removal action, the fan on the cleaning base station 200 draws air in the dust collection air duct, negative pressure is generated after the air in the dust collection air duct is sucked away, so that the air pressure in the dust collection cavity 12 is greater than the air pressure at the communication position of the dust collection air duct and the cleaning base station 200, and the switch door 45 can be opened under the action of the air due to the pressure difference formed at the two sides of the switch door 45.

It should be noted that, in the above-mentioned scheme, the door 451 needs to rely on the suction device 25 when being closed, if the suction device 25 does not work, the door 451 is always in an open state, so that small animals such as cockroaches and mice in the external environment can enter the housing 10 through the dust collecting channel 13, and further the risk of damaging the cleaning robot 100 increases, and in this regard, the door 451 is rotatably connected to the inner wall of the dust collecting channel 13 at the top.

When the door body 451 is opened by an external force, the door body 451 is rotatably connected to the inner wall of the dust collecting channel 13 at a position above the free side of the door body 451, so that the door body 451 can rotate downward by gravity after the external force is removed, thereby completing the closing of the dust collecting channel 13, and thus the closing of the door body 451 is not affected by the suction device 25.

Still further, the switch door 45 further includes an elastic restoring member 452, where the elastic restoring member 452 is installed in the dust collecting channel 13 and acts on the door body 451, so that the door body 451 always has a tendency to switch from the open state to the closed state, and the elastic restoring member 452 can apply an elastic tensile force to the door body 451 when the door body 451 is in the open state, and the elastic restoring member 452 can also apply an elastic pressure to the door body 451 when the door body 451 is in the closed state, which is not limited herein.

Because the door body 451 is switched from the open state to the closed state, the door body 451 not only swings downward under the action of gravity of the door body 451, but also swings downward under the action of the elastic reset member 452, so that the door body 451 is ensured to be quickly closed after the external force is removed, and meanwhile, the door body 451 is ensured to be kept in the closed state when the cleaning robot 100 is turned over.

It should be noted that, the elastic restoring member 452 may be a structural member capable of generating elastic deformation, such as a tension spring, a compression spring, a torsion spring, a spring piece, etc., preferably, the elastic restoring member 452 is a torsion spring, the torsion spring is sleeved on a shaft rotationally connected with the inner wall of the dust collecting channel 13, one end of the torsion spring is abutted against the plate surface of the door 451 opposite to the dust collecting cavity 12, and the other end of the torsion spring is abutted against the inner wall of the dust collecting channel 13.

It should be noted that when the door body 451 rotates to close the dust collecting channel 13, the free end of the door body 451 is easy to be blocked if it is in direct contact with the inner wall of the bottom portion of the dust collecting channel 13, therefore, in some embodiments of the present invention, referring to fig. 1, the inner wall of the bottom portion of the dust collecting channel 13 is provided with a protruding abutment protrusion 14, the protruding abutment 14 extends along the width direction of the dust collecting channel 13, the protruding abutment 14 is located at the rear of the rotational connection position of the door body 451 and the dust collecting channel 13, and the limiting protrusion is used to abut against the free end of the door body 451, so that the free end of the door body 451 is spaced from the inner wall of the bottom portion of the dust collecting channel 13. So arranged, the problem that the door body 451 is blocked due to the contact between the free end of the door body 451 and the bottom wall of the dust collecting channel 13 at the bottom is avoided.

Further, the cross section of the limit protrusion in the front-rear direction of the housing 10 is triangular, and the surface of the limit protrusion facing the top of the dust collecting channel 13 is a convex arc surface, and the surface of the limit protrusion far away from the dust collecting cavity 12 is used for abutting against the free end of the door body 451. By the arrangement, the influence of the limit protrusions on the air flow can be reduced, so that dust, paper scraps and other garbage in the dust collecting cavity 12 is prevented from being disturbed in discharging.

It should be noted that the dust, paper dust and other garbage in the dust collecting chamber 12 of the cleaning robot 100 can be directly collected by the cleaning base station 200 and then intensively treated, and the dust, paper dust and other garbage in the dust collecting chamber 12 of the cleaning robot 100 should be separately treated, and therefore, referring to fig. 1 and 2, the dust collecting chamber 12 of the cleaning robot 100 is preferably formed by a dust collecting box 50 assembled on the housing 10, and the dust collecting box 50 is detachably connected with the housing 10, so that a user can conveniently select a way of treating the dust, paper dust and other garbage in the cleaning robot 100.

Considering that the dust box 50 can be removed from the housing 10, this results in that dust, paper dust and other waste collected inside the dust box 50 easily leaks from the dust outlet 53, and referring to fig. 1 and 4, the dust outlet 53 of the dust box 50 is provided with a movable door 54, the movable door 54 is opened when the cleaning robot 100 collects dust with the cleaning base station 200, and the movable door 54 is closed when the cleaning robot 100 is in a cleaning operation or after the dust collection is completed, thus ensuring that the dust outlet 53 of the dust box 50 is closed when the dust box 50 is removed from the housing 10, and further avoiding the leakage of dust, paper dust and other waste inside the dust box 50.

It should be noted that the structure of the movable door 54 may be the same as that of the opening/closing door 45, and the structure of the movable door 54 may be different from that of the opening/closing door 45, which is not particularly limited herein, in some embodiments of the present invention, the movable door 54 includes a movable plate 541 rotatably mounted on the outer surface of the dust box 50, and the movable plate 541 extends into the dust collecting channel 13 and opens the dust outlet 53 when the air in the dust collecting channel flows from the end adjacent to the dust collecting cavity 12 to the end far from the dust collecting cavity 12; the movable plate 541 closes the dust outlet 53 when air in the dust collection duct flows from an end thereof remote from the dust collection chamber 12 to an end thereof remote from the dust collection chamber 12. So set up, be convenient for go out the opening and closing of dirt mouth 53, simultaneously still can make full use of the effort that produces movable plate 541 when the air flows, and then saved to set up actuating mechanism alone and drive movable plate 541 rotation, optimized cleaning robot 100's overall structure.

Further, the movable plate 541 is rotatably connected to the dust box 50 above the dust outlet 53, so that when the movable plate 541 is switched from the open state to the closed state, the movable plate 541 can rotate downward by gravity, thereby completing the closing of the dust outlet 53, and thus the closing of the movable plate 541 is not affected by the suction device 25.

Still further, the movable door 54 further includes a reset elastic member 542, and the reset elastic member 542 is mounted on the dust box 50 and acts on the movable plate 541, so that the movable plate 541 always has a movement tendency to switch from the open state to the closed state, so that the movable plate 541 is further acted by the reset elastic member 542 when closed, so that the movable plate 541 can quickly close the dust outlet 53 under the condition that other external forces are removed, and in addition, the problem that the movable plate 541 can open the dust outlet 53 due to shaking of the dust box 50 when the dust box 50 is removed from the housing 10 can be avoided.
