In this way, the dust and debris temporarily stored in various positions of the inner cavity of the dust collection box can be cleaned up by the air flow, avoiding the problem that the dust and debris accumulate in the inner cavity of the dust collection box and cannot be cleaned out.

[0034] An embodiment of the present invention provides a dust collecting plate 1. The dust collecting plate 1 and a dust collecting box 100 are assembled to form a dust collecting device, and then the dust collecting device is applied to a cleaning robot. When the cleaning robot cleans the floor, the dust and debris cleaned out can be centrally stored in the dust collecting box. Then, the cleaning robot enters the base station, and by docking the negative pressure system in the base station with the dust collecting device, the dust and debris collected in the dust collecting box 100 can be cleaned up.

[0035] As Figures 1 to 3 shown, it shows a schematic structural diagram of the first embodiment of the dust collecting plate 1 of the embodiment of the present invention.

[0036] Please refer to Figures 1 to 3 , Figures 6 to 8 , the dust collecting plate 1 is assembled at the air inlet 101 of the dust collecting box 100. Specifically, the dust collecting plate 1 includes a plate body 10 and a wind guiding part 20. The plate body 10 is provided with a connection structure for connecting with the dust collecting box 100, and the plate body 10 can rotate relative to the dust collecting box 100 through the connection structure to open or close the air inlet 101 of the dust collecting box 100. After the dust collecting plate 1 is assembled on the dust collecting box 100, the dust collecting plate 1 is located in the inner cavity 103 of the dust collecting box 100. The wind guiding part 20 is arranged on one side of the plate body 10 facing away from the air outlet 102 of the dust collecting box 100. The wind guiding part 20 can pass through the air inlet 101. The wind guiding part 20 has a first wind guiding surface 21 and a second wind guiding surface 22. The first wind guiding surface 21 is connected to the second wind guiding surface 22. The first wind guiding surface 21 and the second wind guiding surface 22 are used to respectively guide the airflow sent into the interior of the dust collecting box 100 from the air inlet 101 of the dust collecting box 100 to blow to opposite sides inside the dust collecting box 100.

[0037] The dust collecting plate 1 is assembled at the air inlet 101 of the dust collecting box 100. During the process of the cleaning robot cleaning the floor, the fan in the cleaning robot generates an air flow. Since the dust collecting plate 1 is rotatably assembled at the air inlet 101 of the dust collecting box 100 through a connecting structure, the dust collecting plate 1 will rotate under the action of the air flow to open the air inlet 101 (when the fan of the cleaning robot stops running, the dust collecting plate 1 loses the action of the air flow and rotates downward under its own gravity to close the air inlet 101). Moreover, the dust and debris cleaned out are transported into the inner cavity 103 of the dust collecting box 100 for temporary storage under the action of the air flow (at this time, the air outlet 102 of the dust collecting box 100 is in a closed state). Since the first air guiding surface 21 and the second air guiding surface 22 are provided on the dust collecting plate 1, the dust and debris carried by the air flow are respectively guided and blown by the first air guiding surface 21 and the second air guiding surface 22 to reach the corner positions (i.e., the "dead corner" positions) of the inner cavity 103 of the dust collecting box 100, improving the effective utilization rate of the volume of the dust collecting box 100. When the cleaning robot enters the base station, the air outlet 102 of the dust collecting box 100 will be docked with the negative pressure system of the base station. Then, the negative pressure system generates an air flow (the air flow flows from the air inlet 101 to the air outlet 102, and at this time, a negative pressure is formed in the inner cavity of the dust collecting box 100). The dust collecting plate 1 rotates relative to the dust collecting box 100 under the action of the air flow negative pressure to open the air inlet 101 (when the negative pressure system stops running, the dust collecting plate 1 loses the action of the air flow and rotates downward under its own gravity to close the air inlet 101). Since the first air guiding surface 21 and the second air guiding surface 22 are provided on the dust collecting plate 1, the air flow is respectively guided and blown by the first air guiding surface 21 and the second air guiding surface 22 to the corner positions of the dust collecting box 100, so that the dust and debris temporarily stored in the corner positions are blown from the air outlet 102 into the trash bin of the base station. In this way, the dust and debris temporarily stored at various positions in the inner cavity 103 of the dust collecting box 100 can be cleaned by the air flow, avoiding the problem that the dust and debris accumulate in the inner cavity 103 of the dust collecting box 100 and cannot be cleaned out. When the plate body 10 falls to close the air inlet 101, the inner cavity 103 of the dust collecting box 100 is in a sealed state, and the dust and debris temporarily stored in the inner cavity 103 cannot flow back from the air inlet 101, effectively preventing the situation of dust and debris flowing back.

[0038] In this embodiment, as Figure 2As shown, the first air guiding surface 21 and the second air guiding surface 22 are symmetrically arranged with respect to the symmetry plane perpendicular to the plate surface of the plate body 10. In this way, the airflows guided by the first air guiding surface 21 and the second air guiding surface 22 and blown to both sides of the inner cavity 103 of the dust collection box 100 are made uniform, so that the air pressures at various positions in the inner cavity 103 are made uniform. Further, both the first air guiding surface 21 and the second air guiding surface 22 are flat surfaces; or, both the first air guiding surface 21 and the second air guiding surface 22 are arc surfaces. In the first embodiment, it is preferably that both the first air guiding surface 21 and the second air guiding surface 22 are flat surfaces.

[0039] Alternatively, the first air guiding surface 21 and the second air guiding surface 22 may also be asymmetrically arranged, that is: the first air guiding surface 21 is a flat surface and the second air guiding surface 22 is an arc surface; or, the first air guiding surface 21 is an arc surface and the second air guiding surface 22 is a flat surface.

[0040] As Figure 2 and Figure 3 shown, the air guiding part 20 includes a convex structure provided on the air inlet side of the plate body 10, and the convex structure is a hollow structure, that is, the convex structure has a hollow cavity 203. In this way, the weight of the dust collection plate 1 can be reduced as much as possible. The first air guiding surface 21 and the second air guiding surface 22 are arranged on the side wall of the convex structure. Further, a connecting surface (not shown) is also provided on the side wall of the convex structure, and the first air guiding surface 21, the connecting surface and the second air guiding surface 22 are connected in sequence.

[0041] For the convenience of manufacturing the dust collection plate 1, therefore, the plate body 10 and the convex structure are of an integrally formed structure. As Figure 3 shown, the dust collection plate 1 is manufactured by an injection molding process, and the hollow cavity 203 is a cavity opening towards the windward side of the plate body 10. In addition, the hollow cavity 203 may also be a closed cavity space. At this time, the plate body 10 is a whole plate member, and the convex structure is assembled and fixed on the plate surface of the plate body 10. Specifically, the convex structure can be fixed on the plate body by fusion welding (the dust collection plate 1 is made of plastic material), or can be fixedly connected to the plate body 10 by screws.

[0042] As Figure 1 and Figure 2 shown, the connecting structure includes a first rotating ear 111 and a second rotating ear 112. The first rotating ear 111 and the second rotating ear 112 are parallel and extend along the same axis. The plate body 10 is rotatably assembled to the dust collection box 100 through the first rotating ear 111 and the second rotating ear 112. In a direction perpendicular to and away from this axis, the first air guiding surface 21 and the second air guiding surface are arranged in a gradually expanding shape, so as to guide the airflow and blow it to opposite sides of the inner cavity 103 of the dust collection box 100.

[0043] As Figure 4As shown, it shows a schematic structural diagram of the second embodiment of the dust collection plate 1 of the embodiment of the present invention.

[0044] In the second embodiment, the air guiding part 20 includes a connected first air guiding plate 201 and a second air guiding plate 202. Both the first air guiding plate 201 and the second air guiding plate 202 are arranged on the air inlet side surface of the plate main body 10. The first air guiding surface 21 and the second air guiding surface 22 are respectively the windward surfaces of the first air guiding plate 201 and the second air guiding plate 202 (the windward surface is the surface of the first air guiding plate 201 and the second air guiding plate 202 facing the connected surface).

[0045] The plate main body 10, the first air guiding plate 201 and the second air guiding plate 202 are of an integrally formed structure.

[0046] Compared with the first embodiment, in the second embodiment, except for the above different structures, the remaining structures are the same, so they will not be elaborated here.

[0047] As Figures 5 to 8 shown, it shows a schematic structural diagram of the dust collection device of the embodiment of the present invention.

[0048] Specifically, the dust collection device includes a dust collection box 100, a dust collection plate 1 and a dust blocking piece 104. The dust collection box 100 is provided with an inner cavity 103, an air inlet 101 and an air outlet 102 communicating with the inner cavity 103. Among them, the dust collection plate 1 is the aforementioned dust collection plate 1. The dust collection plate 1 is rotatably installed at the air inlet 101 through a connection structure. The dust blocking piece 104 is installed at the air outlet 102, and the dust blocking piece 104 is used to open or close the air outlet 102.

[0049] In this dust collection device, the dust collection box 100 includes an upper box body 110 and a lower box body 120. The lower box body 120 is the base, and the upper box body 110 covers the lower box body 120 to form an inner cavity 103 for storing dust and debris.

[0050] The dust collecting plate 1 is assembled at the air inlet 101 of the dust collecting box 100. During the process of the cleaning robot cleaning the floor, the fan in the cleaning robot generates an air flow. Since the dust collecting plate 1 is rotatably assembled at the air inlet 101 of the dust collecting box 100 through a connecting structure, the dust collecting plate 1 will rotate under the action of the air flow to open the air inlet 101. Moreover, the dust and debris cleaned out are transported into the inner cavity 103 of the dust collecting box 100 for temporary storage under the action of the air flow. At this time, the air outlet 102 of the dust collecting box 100 is closed by the dust blocking piece 104. Since the first air guiding surface 21 and the second air guiding surface 22 are provided on the dust collecting plate 1, the dust and debris carried by the air flow are respectively guided and blown by the first air guiding surface 21 and the second air guiding surface 22 to reach the corner positions (i.e., the "dead corner" positions) of the inner cavity 103 of the dust collecting box 100, improving the effective utilization rate of the volume of the dust collecting box 100. When the cleaning robot enters the base station, the air outlet 102 of the dust collecting box 100 will be docked with the negative pressure system of the base station. At this time, the dust blocking piece 104 opens the air outlet 102, and then the negative pressure system generates an air flow (the air flow flows from the air inlet 101 to the air outlet 102, and at this time, a negative pressure is formed in the inner cavity of the dust collecting box 100). The dust collecting plate 1 rotates relative to the dust collecting box 100 under the action of the air flow negative pressure to open the air inlet 101. Since the first air guiding surface 21 and the second air guiding surface 22 are provided on the dust collecting plate 1, the air flow is respectively guided and blown by the first air guiding surface 21 and the second air guiding surface 22 to the corner positions of the dust collecting box 100, so that the dust and debris temporarily stored in the corner positions are blown into the dust bin of the base station from the air outlet 102. In this way, the dust and debris temporarily stored at various positions in the inner cavity 103 of the dust collecting box 100 can be cleaned up by the air flow, avoiding the problem that the dust and debris accumulate in the inner cavity 103 of the dust collecting box 100 and cannot be cleaned out.

[0051] As Figure 8 shown, the dust collecting device further includes a battery module 200 and a connector 300. A first assembly groove 105 is provided at the top of the dust collecting box 100 (the first assembly groove 105 is provided on the upper box body 110). The battery module 200 is installed in the first assembly groove 105 and then covered by a first cover plate 401, so as to seal and install the battery module 200 in the first assembly groove 105. The dust collecting box 100 further has a first mounting seat 106 (the first mounting seat 106 is provided on the side wall of the lower box body 120). The connector 300 is installed in the first mounting seat 106. The battery module 200 is electrically connected to the connector 300. When the dust collecting device is assembled to the cleaning robot, the connector 300 is electrically connected to the electrical equipment of the cleaning robot, and the battery module 200 supplies power to the electrical equipment to ensure the normal operation of the cleaning robot.

[0052] As Figure 8As shown in the figure, a second assembly groove 108 is further provided on the lower box body 120, and a locking structure 50 is assembled in the second assembly groove 108. When the dust collection device is installed on the cleaning robot, the dust collection device is locked on the cleaning robot through the locking structure 50. Specifically, the locking structure 50 includes a locking tongue member 51, a spring 52, and a pushing member 53. The spring 52 is installed in the second assembly groove 108, and then the locking tongue member 51 is installed so that the locking tongue member 51 compresses the spring 52. Then the pushing member 53 is installed, and finally the locking structure 50 is stabilized by the second cover plate 402. At this time, the locking tongue member 51 passes through the second cover plate 402, and the locking tongue member 51 cooperates with the locking member in the cleaning robot to achieve the locking function. When unlocking is required, the pushing member 53 is used to push the locking tongue member 51, so that the locking tongue member 51 continues to compress the spring 52 and descend, so that the locking tongue member 51 disengages from the locking member in the cleaning robot, realizing unlocking. In this embodiment, there are two pushing members 53, and the two pushing members 53 are symmetrically arranged on both sides of the locking tongue member 51. Moreover, a second mounting seat 107 is provided on the other side wall of the lower box body 120 (in this embodiment, the first mounting seat 106 and the second mounting seat 107 are symmetrically arranged). The second mounting seat 107 is used to mount a driving motor, and the driving motor is drivingly connected to the dust blocking piece 104. The dust blocking piece 104 is driven to rotate by the driving motor, so as to open or close the air outlet 102.

[0053] According to another aspect of the embodiments of the present invention, a cleaning robot is provided. Specifically, the cleaning robot includes the aforementioned dust collection device.

[0054] The dust collecting plate 1 is assembled at the air inlet 101 of the dust collecting box 100. During the process of the cleaning robot cleaning the floor, the fan in the cleaning robot generates an air flow. Since the dust collecting plate 1 is rotatably assembled at the air inlet 101 of the dust collecting box 100 through a connecting structure, the dust collecting plate 1 will rotate under the action of the air flow to open the air inlet 101. Moreover, the dust and debris cleaned out are transported into the inner cavity 103 of the dust collecting box 100 for temporary storage under the action of the air flow. At this time, the air outlet 102 of the dust collecting box 100 is closed by the dust blocking piece 104. Since the first air guiding surface 21 and the second air guiding surface 22 are arranged on the dust collecting plate 1, the dust and debris carried by the air flow are respectively guided and blown by the first air guiding surface 21 and the second air guiding surface 22 to reach the corner positions (i.e., the "dead corner" positions) of the inner cavity 103 of the dust collecting box 100, improving the effective utilization rate of the volume of the dust collecting box 100. When the cleaning robot enters the base station, the air outlet 102 of the dust collecting box 100 will be docked with the negative pressure system of the base station. At this time, the dust blocking piece 104 opens the air outlet 102, and then the negative pressure system generates an air flow (the air flow flows from the air inlet 101 to the air outlet 102, and at this time, a negative pressure is formed in the inner cavity of the dust collecting box 100). The dust collecting plate 1 rotates relative to the dust collecting box 100 under the action of the air flow negative pressure to open the air inlet 101. Since the first air guiding surface 21 and the second air guiding surface 22 are arranged on the dust collecting plate 1, the air flow is respectively guided and blown by the first air guiding surface 21 and the second air guiding surface 22 to the corner positions of the dust collecting box 100, so that the dust and debris temporarily stored in the corner positions are blown into the dust bin of the base station from the air outlet 102. In this way, the dust and debris temporarily stored at various positions in the inner cavity 103 of the dust collecting box 100 can be cleaned up by the air flow, avoiding the problem that the dust and debris accumulate in the inner cavity 103 of the dust collecting box 100 and cannot be cleaned out.

[0055] The above are only the preferred embodiments of the embodiments of the present invention, and are not intended to limit the embodiments of the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the embodiments of the present invention shall be included in the protection scope of the embodiments of the present invention.
