[0035] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0036] As shown in FIG. 1 and FIG. 2 , in one embodiment, a cleaning device is provided, comprising a base station 2 and a cleaning robot 1. The cleaning robot 1 comprises a dust collecting box 10 provided with a dust exhaust passage 130. The base station 2 is provided with a dust collecting passage 31 having a dust collecting inlet, the dust collecting inlet being located on the bottom surface of the base station 2 and configured to dock with the dust exhaust passage 130 when the cleaning robot 1 returns to the base station 2.

[0037] Specifically in this embodiment, the base station 2 includes a dust collecting fan and a dust collecting part, and the dust collecting channel 31, the dust collecting part and the dust collecting fan are connected in sequence. In this way, the cleaning robot 1 will suck the garbage into the dust collecting box 10 when working, and store it in the dust collecting box 10. When the cleaning robot 1 returns to the base station 2 after completing the cleaning work, the dust collecting fan collects the garbage in the dust collecting box 10 into the dust collecting part. Specifically, during the dust collection work, the cleaning robot 1 returns to the base station 2, and after the dust exhaust channel 130 is docked with the dust collection inlet of the dust collecting channel 31, the dust collecting fan is turned on, and the dust collecting box 10 is opened under the action of the suction force of the dust collecting fan, and the garbage in the dust collecting box 10 is discharged from the dust exhaust channel 130, and finally enters the dust collecting part through the dust collecting channel 31.

[0038] The dust collecting part may be configured as an integrated bucket, a dust collecting bag or other dust collecting structures. The cleaning robot 1 may be configured as a sweeper, a floor scrubber or other cleaning devices.

[0039] As shown in FIG3 , in one embodiment, a cleaning robot 1 is provided, comprising a robot body 20 and a dust box 10. The robot body 20 is provided with a dust box installation cavity 21, and the dust box 10 is installed in the dust box installation cavity 21. In this way, the dust box 10 can be detachably installed in the dust box installation cavity 21, thereby improving the practicality of the cleaning robot 1.

[0040] The dust box 10 can be installed in the dust box installation cavity 21 by snapping, plugging or other detachable methods.

[0041] Specifically in this embodiment, the robot body 20 includes a dust suction fan and a roller brush. The dust suction fan is connected to the dust box 10 and is used to cooperate with the roller brush to suck the garbage on the surface to be cleaned into the dust box 10.

[0042] As shown in Fig. 4, Fig. 5 and Fig. 7, in one embodiment, a dust box 10 is provided, comprising a dust box body 100 and a dust exhaust cover 200. The dust box body 100 is provided with a dust collecting chamber 110, and the bottom wall of the dust collecting chamber 110 is provided with a dust exhaust port 120 arranged obliquely. The bottom wall of the dust box body 100 is provided with a dust exhaust channel 130, and the dust exhaust channel 130 is communicated with the dust exhaust port 120, so that the garbage in the dust collecting chamber 110 is discharged from the bottom of the dust box body 100. The dust exhaust cover 200 is rotatably matched with the bottom wall of the dust box body 100, so that the dust exhaust port 120 can be opened or closed under the action of an external force.

[0043] In the dust box 10 of the above embodiment, when the cleaning robot 1 is working, the dust suction fan cooperates with the roller brush to suck the garbage on the surface to be cleaned into the dust collection chamber 110 and store it in the dust collection chamber 110. When the cleaning robot 1 completes the cleaning work and returns to the base station 2, the dust discharge channel 130 docks with the dust collection inlet of the dust collection channel 31. At this time, the dust collection fan has not been turned on, and the dust discharge cover 200 is in a closed state to close the dust discharge port 120. The dust collection fan is turned on, and the dust discharge cover 200 moves to an open state under the action of the suction force of the dust collection fan to open the dust discharge port 120. The dust collection chamber 110, the dust discharge port 120 and the dust discharge channel 130 are connected in sequence, and the garbage in the dust collection chamber 110 is discharged from the dust discharge channel 130 to the dust box body 100, and finally enters the dust collection part through the dust collection channel 31. The dust box 10 in the present application adopts a bottom suction dust discharge port 120, and the dust discharge port 120 is arranged at an angle. When garbage is sucked into the dust collection chamber 110, the garbage is not easy to cover and block the dust discharge port 120, so as to prevent the garbage from piling up at the dust discharge port 120 and blocking the dust discharge port 120 during dust discharge, thereby ensuring the dust discharge efficiency and improving the reliability of the dust box 10. In addition, the dust discharge port 120 is arranged at an angle, and the dust discharge channel 130 is arranged at the bottom of the dust box body 100. The airflow is bent in the dust box body 100, which helps to better discharge the garbage in the dust collection chamber 110 and improve the dust discharge efficiency of the dust box 10.

[0044] It should be noted that, compared with the solution in which the dust exhaust port 120 is horizontally arranged on the bottom wall of the dust collecting chamber 110, the dust exhaust port 120 in the present application is obliquely arranged on one side of the bottom wall of the dust collecting chamber 110, which can better discharge the garbage on the side of the dust collecting chamber 110 away from the dust exhaust port 120.

[0045] The bottom wall of the dust collecting chamber 110 may be tilted as a whole or partially.

[0046] As shown in Fig. 5 and Fig. 6, further, the bottom wall of the dust collecting chamber 110 includes an inclined surface 111 and a plane 112, and the dust discharge port 120 is arranged on the inclined surface 111, and the inclined surface 111 is located above and to the side of the plane 112. In this way, the garbage on the inclined surface 111 will slide down to the plane 112 under the action of gravity, so that the garbage is not easy to accumulate at the dust discharge port 120, thereby improving the reliability of the dust collecting box 10.

[0047] It should be noted that the side upper direction refers to the direction deviating from the upper direction to the side direction. Specifically in the present application, the inclined surface 111 is located on the side upper direction of the plane 112, which means that the inclined surface 111 is located on the upper direction of the plane 112 and deviates from the side direction. As shown in FIG6 , the inclined surface 111 is located on the upper direction of the plane 112 and deviates from the left side direction.

[0048] The inclination angle of the inclined surface 111 can be flexibly adjusted according to the actual use requirements. The inclined surface 111 and the plane 112 can directly intersect or be arranged at intervals.

[0049] Specifically in this embodiment, the inclined surface 111 and the plane 112 are respectively located on the left and right sides of the bottom wall of the dust collecting chamber 110. For example, the inclined surface 111 is provided on the left side of the bottom wall of the dust collecting box 10, and the plane 112 is provided on the right side of the bottom wall of the dust collecting box 10. The dust discharge port 120 is provided at the left rear side of the inclined surface 111. The dust discharge channel 130 extends in the vertical direction and is located directly below the dust discharge port 120.

[0050] In other embodiments, the front and rear sides of the bottom wall of the dust box 10 may be respectively set as the inclined surface 111 and the plane 112. Alternatively, one corner of the bottom wall of the dust box 10 may be set as the inclined surface 111, and the other areas of the bottom wall of the dust box 10 may be set as the plane 112.

[0051] As shown in Fig. 5 and Fig. 6, optionally, the inclined surface 111 and the plane 112 are spaced apart in the vertical direction. The bottom wall of the dust collecting chamber 110 also includes a connecting surface 113, which is located between the inclined surface 111 and the plane 112 and intersects with both the inclined surface 111 and the plane 112. In this way, the connecting surface 113 can increase the height of the dust discharge port 120 relative to the plane 112. When garbage is sucked into the dust collecting chamber 110, the garbage accumulates at the connecting surface 113, that is, the garbage is not easy to accumulate at the dust discharge port 120, which prevents the garbage from piling up at the dust discharge port 120 and blocking the dust discharge port 120 during dust discharge, thereby ensuring the dust discharge efficiency and improving the reliability of the dust collecting box 10.

[0052] The connecting surface 113 may be an inclined surface or an arc surface. When the connecting surface 113 is an inclined surface, the inclination angle of the connecting surface 113 may be the same as the inclination angle of the inclined surface 111 or may be different from the inclination angle of the inclined surface 111 .

[0053] As shown in FIG. 6 , in one embodiment, the surface where the dust exhaust port 120 is located forms an acute angle α with the horizontal plane, and the value range of the acute angle α is greater than or equal to 12° and less than or equal to 18°.

[0054] Specifically in this embodiment, the acute angle α can also be understood as the angle between the dust discharge port 120 and the bottom wall of the dust box body 100. The dust discharge port 120 itself forms an inclined surface (i.e., the inclined surface 111). As shown in Figures 4, 5 and 7, optionally, the front wall of the dust box body 100 is provided with a dust inlet 140 connected to the dust collecting chamber 110, and the dust discharge port 120 is located on one side of the dust inlet 140 along the left-right direction (the direction shown in B in Figure 4). In this way, the dust inlet 140 and the dust discharge port 120 are staggered, so that the bending amplitude of the airflow in the dust box body 100 is increased during dust collection operation, which is further beneficial to the discharge of garbage in the dust collecting chamber 110 and improves the dust discharge efficiency of the dust box 10.

[0055] It should be noted that the front wall of the dust box body 100 refers to the side wall of the dust box body 100 that is closest to the front along the cleaning direction of the cleaning robot 1. The relative position between the dust inlet 140 and the dust outlet 120 can be flexibly adjusted according to the actual needs of use. Specifically in this embodiment, the dust inlet 140 is arranged corresponding to the roller brush so that the garbage on the roller brush can be sucked into the dust collecting chamber 110.

[0056] As shown in Fig. 4, Fig. 5, Fig. 7 and Fig. 8, in one embodiment, the dust collecting box 10 further comprises an elastic reset member 300, which is connected to both the dust discharge cover 200 and the dust box body 100, and is configured to be elastically deformed when the dust discharge cover 200 opens the dust discharge port 120 under the action of an external force, and to drive the dust discharge cover 200 to reset together when the external force on the dust discharge cover 200 is removed so that the dust discharge cover 200 keeps closing the dust discharge port 120. In this way, the elastic reset member 300 can pre-apply an elastic force to the dust discharge cover 200, ensuring that the dust discharge cover 200 does not open the dust discharge port 120 during normal cleaning, thereby improving the practicality of the dust collecting box 10.

[0057] The elastic reset member 300 may be configured as a spring, an elastic strip or other elastic reset structures.

[0058] As shown in Figure 8 and Fig. 9 As shown, further, the dust outlet 120 is arranged on the inclined surface 111, and the inclined surface 111 is located above and to the side of the plane 112. The dust cover 200 is provided with a connecting portion 210 on a side close to the plane 112, and the connecting portion 210 is provided with a connecting through hole 220. The dust collecting box 10 further includes a rotating shaft 400 located on a side of the dust exhaust channel 130 close to the plane 112, and the rotating shaft 400 passes through the connecting through hole 220 and is connected to the bottom wall of the dust box body 100.

[0059] The rotating shaft 400 may be located directly below the inclined surface 111 , directly below the connecting surface 113 , or directly below the plane 112 .

[0060] Specifically in this embodiment, the dust outlet 120 is arranged in a square shape, and is provided with a first side 121, a second side 122, a third side and a fourth side. The first side 121 and the second side 122 are arranged opposite to each other and both extend in the horizontal direction, the first side 121 is located on the side of the second side 122 close to the plane 112, and the first side 121 is located below the second side 122. The third side and the fourth side are arranged opposite to each other and both extend in an inclined direction. The two ends of the third side are respectively connected to one end of the first side 121 and one end of the second side 122, and the two ends of the fourth side are respectively connected to the other end of the first side 121 and the other end of the second side 122. In other embodiments, the dust outlet 120 can also be arranged in other shapes.

[0061] like Fig. 9 As shown in Figures 10 and 11, optionally, the elastic reset member 300 is configured as a torsion spring. There is at least one connecting portion 210, and each connecting portion 210 is arranged at intervals along the extension direction of the first side 121, and is located on the side of the dust exhaust cover 200 close to the first side 121. Each connecting portion 210 is provided with a connecting through hole 220 along the extension direction of the first side 121. At least one torsion spring is provided between two adjacent connecting portions 210. The rotating shaft 400 passes through each connecting through hole 220 and each torsion spring and is connected to the inner wall of the dust exhaust channel 130. In this way, the dust exhaust cover 200 remains in a closed state under the elastic force of the torsion spring, and opens when the cleaning robot 1 returns to the base station 2 and the dust collecting fan is turned on, thereby improving the practicality of the dust collecting box 10.

[0062] As shown in FIG. 5 , FIG. 7 and FIG. 8 , in one embodiment, the bottom of the dust box body 100 is provided with an annular rim 150, and the annular rim 150 is provided with a dust discharge channel 130 connected to the dust discharge port 120. The inner side wall of the dust discharge port 120 is provided with an annular flange 160 extending toward one side of the dust discharge channel 130. The side of the annular flange 160 close to the first side 121 and the side of the annular rim 150 close to the first side 121 are surrounded to form an installation space 170. The rotating shaft 400 is installed in the installation space 170. In this way, the rotating shaft 400 and the connecting part 210 can be hidden in the installation space 170. When the garbage in the dust collecting chamber 110 is discharged through the dust discharge port 120 and the dust discharge channel 130, the garbage will not enter the installation space 170, ensuring that the garbage will not get stuck in the connection between the dust discharge cover 200 and the dust box body 100, thereby improving the reliability of the dust collecting box 10.

[0063] Specifically in this embodiment, the dust box body 100, the annular flange 160 and the annular surrounding edge 150 are integrally formed.

[0064] Specifically in this embodiment, the torsion spring is provided with a first connection end and a second connection end. The connection portion 210 is provided with a socket for plugging and matching with the first connection end. The inner wall of the installation space 170 is provided with a conflict groove for conflicting and matching with the second connection end.

[0065] As shown in Figures 7 and 8, optionally, the outer wall of the dust exhaust channel 130 close to the dust box body 100 is provided with a reinforcing groove 180 and / or reinforcing ribs. The reinforcing groove 180 and / or reinforcing ribs are located on the side of the dust exhaust port 120 away from the rotating shaft 400.

[0066] Specifically in this embodiment, the side of the annular flange 160 close to the second side 122 is connected to the top of the side of the annular surrounding edge 150 close to the second side 122 as a whole to form an inner convex structure. The outer side wall of the inner convex structure is provided with a reinforcing groove 180 and / or a reinforcing rib. In this way, the reinforcing rib and / or the reinforcing groove 180 can improve the strength of the inner convex structure, prevent the inner convex structure from shrinking, and improve the reliability of the dust box 10.

[0067] Specifically in this embodiment, the second side 122 is set to the left side. The first side 121 is set to the right side. The left outer wall of the annular rim 150 and the left outer wall of the dust box body 100 are located on the same vertical plane. The rear outer wall of the annular rim 150 and the rear outer wall of the dust box body 100 are located on the same vertical plane. The bottom of the annular rim 150 is located below the bottom wall of the dust box body 100, and is used to be inserted and positioned correspondingly with the positioning groove on the bottom wall of the dust box installation cavity 21.

[0068] Figure 8 Fig. 9 As shown in FIG. 10 , optionally, an annular sink 230 is provided on the edge of the dust cover 200. The dust box 10 further includes an annular seal 500, which is mounted on the annular sink 230 and is configured to be located between the annular flange 160 and the dust cover 200 when the dust cover 200 closes the dust outlet 120, so as to seal the annular flange 160 with the dust cover 200. In this way, when the dust cover 200 closes the dust outlet 120, the annular seal 500 can fill the gap between the annular flange 160 and the dust cover 200, so that the sealing between the annular flange 160 and the dust cover 200 is increased, thereby improving the reliability of the dust box 10.

[0069] The annular sealing member 500 may be configured as an annular sealing rubber ring, an annular sealing sponge or other annular sealing structures.

[0070] As shown in Fig. 5, Fig. 7 and Fig. 8, in one embodiment, the dust box body 100 is further provided with an exhaust port 190 communicating with the dust collecting chamber 110. The dust collecting chamber 10 further comprises a filter 600, which is installed in the dust collecting chamber 110 and is used to prevent the garbage in the dust collecting chamber 110 from being discharged from the exhaust port 190 and to allow the airflow in the dust collecting chamber 110 to be discharged from the exhaust port 190. In this way, the filter 600 can prevent the garbage in the dust collecting chamber 110 from being discharged from the exhaust port 190, and the airflow sucked into the dust collecting chamber 110 can be discharged smoothly from the exhaust port 190, thereby improving the practicality of the dust collecting chamber 10.

[0071] In addition, the filter element 600 can be configured as a filter net, a filter cloth or other filter structures. Specifically in this embodiment, the exhaust port 190 is disposed on a side of the top of the dust box body 100 away from the dust outlet 120 .
