Description

Cleaning robots

[0001] This application claims priority to Chinese Patent Application No. 202421672571.5, filed on July 15, 2024, entitled "Cleaning Robot", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of robotics, specifically to a cleaning robot. Background Technology

[0003] Pool cleaning robots are used to clean debris from underwater surfaces, significantly reducing the difficulty and labor costs of underwater cleaning. When cleaning above water, the robot moves by rotating its drive mechanism. The water flow channel for the robot's propellers passes through a debris bin. When the bin is full of debris, the channel can become clogged, preventing sufficient water supply to the propellers. This reduces the thrust from the propellers, slowing down or hindering the robot's movement. Summary of the Invention

[0004] This application provides a cleaning robot that can better prevent the problem of insufficient water replenishment from the second rotating component causing the cleaning robot to slow down.

[0005] In a first aspect, this application provides a cleaning robot, which includes:

[0006] Organism;

[0007] The first rotating component is rotatably disposed at one end of the machine body and is used to clean up the garbage in the area to be cleaned;

[0008] The second rotating component is rotatably disposed at the other end of the body and is used to drive the cleaning robot to move on the water surface;

[0009] A garbage collection device is provided on the body and located between the first rotating member and the second rotating member. The garbage collection device has a garbage collection port on the side facing the first rotating member and a filter hole for separating water and garbage on the side facing the second rotating member.

[0010] A first flow channel is formed between the first rotating component, the waste collection device, and the second rotating component;

[0011] The second flow channel is formed between the inner cavity of the body and the second rotating member.

[0012] Furthermore, in a direction perpendicular to the direction of travel of the cleaning robot, the first rotating member is spaced apart from the body to form a first sub-channel, the second rotating member is spaced apart from the body to form a second sub-channel, the garbage collection port, the inner cavity of the garbage collection device, and the filter hole form a third sub-channel, and the first sub-channel, the third sub-channel, and the second sub-channel are sequentially connected to form the first channel.

[0013] Furthermore, the body includes a first shell and a second shell. The first shell has a receiving groove on the side opposite to the second shell. Along the traveling direction of the cleaning robot, the first rotating member, the garbage collection device, and the second rotating member are sequentially arranged in the receiving groove. The first rotating member and the bottom wall of the receiving groove form a first sub-channel, and the second rotating member and the bottom wall of the receiving groove form a second sub-channel.

[0014] Furthermore, the inner cavity of the body includes an adjacent and communicable main cavity and a secondary cavity. In the direction perpendicular to the direction of travel of the cleaning robot, the secondary cavity is spaced apart from the second rotating member. The side of the secondary cavity facing the second rotating member has an opening. The main cavity is formed as a fourth sub-flow channel, and the secondary cavity is formed as a fifth sub-flow channel. The fourth sub-flow channel and the fifth sub-flow channel form the second flow channel.

[0015] Furthermore, the secondary cavity includes a first secondary cavity and a second secondary cavity, with a partition plate horizontally disposed between the first secondary cavity and the second secondary cavity. The partition plate has a first through hole, and the opening is constructed on the side of the second secondary cavity opposite to the partition plate.

[0016] Furthermore, a second through hole and a blocking member are constructed on the side wall between the main cavity and the secondary cavity. The blocking member is flipped and disposed on the side wall and covers the second through hole. When the cleaning robot is cleaning the water surface, the second through hole is in the open state, and when the cleaning robot is cleaning underwater, the second through hole is in the closed state.

[0017] Furthermore, the cleaning robot also includes a water pump assembly, and the shield is located in the secondary cavity. When the water pump assembly is started, the shield is pressed tightly against the second through hole under the action of negative pressure. When the water pump assembly is turned off, the shield can open the second through hole under the action of water flow.

[0018] Furthermore, a third through hole is constructed on the side of the secondary cavity opposite to the opening.

[0019] Furthermore, the cleaning robot also includes an isolation cover, which is located inside the body and has several fourth through holes.

[0020] Furthermore, the waste collection device has an inclined surface on the side wall near the body and near the waste collection port.

[0021] When the cleaning robot only has a first flow channel, the first flow channel passes through the garbage collection device. When there is a lot of garbage in the garbage collection device, it is easy to clog the filter holes of the garbage collection device, thereby reducing the water flow of the first flow channel, reducing the water supply of the second rotating component, and reducing the thrust of the drive propeller on the pool cleaning robot, making the movement of the pool cleaning robot slower or obstructed. The cleaning robot of this application embodiment includes a first flow channel and a second flow channel. The first flow channel is formed between the first rotating component, the garbage collection device, and the second rotating component; the second flow channel is formed between the inner cavity of the body and the second rotating component. In this way, when the cleaning robot cleans the water surface, the two flow channels can increase the speed of water flow to the second rotating component, increase the thrust of the second rotating component on the cleaning robot, and even if the water flow of the first flow channel decreases or even becomes blocked, it will not reduce the water supply of the drive propeller and affect the movement of the cleaning robot.

Detailed Implementation

[0033] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0034] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0035] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0036] It should be noted that, for ease of explanation, the same reference numerals denote the same components in the embodiments of this application, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments.

[0037] Pool cleaning robots are used to clean debris from underwater surfaces, significantly reducing the difficulty and labor costs of underwater cleaning. When cleaning above water, the robot moves by rotating its drive mechanism. The water flow channel for the robot's propellers passes through a debris bin. When the bin is full of debris, the channel can become clogged, preventing sufficient water supply to the propellers. This reduces the thrust from the propellers, slowing down or hindering the robot's movement.

[0038] Please refer to Figures 1 to 4. This application embodiment provides a cleaning robot 100, which includes: a body 10; a first rotating member 20, rotatably disposed at one end of the body 10, for cleaning garbage in the area to be cleaned; a second rotating member 30, rotatably disposed at the other end of the body 10, for driving the cleaning robot 100 to move on the water surface; a garbage collection device 40, disposed on the body 10 and located between the first rotating member 20 and the second rotating member 30, the garbage collection device 40 having a garbage collection port 41 on the side facing the first rotating member 20 and a filter hole 42 for separating water and garbage on the side facing the second rotating member 30; a first flow channel 50 formed between the first rotating member 20, the garbage collection device 40, and the second rotating member 30; and a second flow channel 60 formed between the inner cavity 11 of the body 10 and the second rotating member 30.

[0039] The cleaning robot 100 of this application embodiment can be applied to cleaning trash in swimming pools, ponds, etc. It can clean trash on the water surface, and can also submerge underwater to clean underwater trash, as well as clean the surface of the pool bottom and side walls.

[0040] Optionally, the area to be cleaned may include, but is not limited to, at least one of the following: pool bottom, pool sidewall, water tank bottom, water tank sidewall, and water surface.

[0041] The cleaning robot 100 of this application embodiment has an upright state (as shown in FIG1) and an inverted state (as shown in FIG2). The upright state is used for underwater cleaning, and the inverted state is used for surface cleaning. It can be understood that the upright state and the inverted state are opposite.

[0042] Understandably, the size of the garbage collection port 41 is larger than the size of the filter hole 42, so that after the garbage flows into the garbage collection device 40 with the water through the garbage collection port 41, the garbage is blocked in the garbage collection device 40 by the filter hole 42, and the water flows out of the garbage collection device 40 through the filter hole 42.

[0043] It should be noted that the second rotating component 30, the garbage collection device 40, and the first rotating component 20 are arranged sequentially along the traveling direction (also known as the driving direction or movement direction) of the cleaning robot 100. In other words, the traveling direction of the cleaning robot 100 is the direction in which the second rotating component 30 points towards the first rotating component 20.

[0044] Understandably, the body 10 includes an inner cavity 11.

[0045] Understandably, the first rotating component 20, the garbage collection device 40 and the second rotating component 30 are located on the same side of the body 10, and the first rotating component 20 and the second rotating component 30 are located at opposite ends of the body 10.

[0046] Optionally, the first rotating member 20 can be, but is not limited to, at least one of a cleaning brush, a roller brush, etc.

[0047] Optionally, the second rotating member 30 may be, but is not limited to, a drive propeller.

[0048] Understandably, the garbage collection port 41 and the filter hole 42 are located on opposite sides of the garbage collection device 40 along the direction of travel of the cleaning robot 100.

[0049] Optionally, the number of filter holes 42 is multiple, and the multiple filter holes 42 are arranged at intervals.

[0050] It should be noted that the body 10 has an inner cavity 11, and the second flow channel 60 is located inside the body 10.

[0051] When the cleaning robot 100 only has the first flow channel 50, the first flow channel 50 passes through the garbage collection device 40. When there is a lot of garbage in the garbage collection device 40, it is easy to clog the filter hole 42 of the garbage collection device 40, thereby reducing the water flow of the first flow channel 50, reducing the water replenishment of the second rotating component 30, and reducing the thrust of the drive paddle on the pool cleaning robot 100, which makes the movement of the pool cleaning robot 100 slower or obstructed. The cleaning robot 100 of this application embodiment includes a first flow channel 50 and a second flow channel 60. The first flow channel 50 is formed between the first rotating member 20, the garbage collection device 40, and the second rotating member 30. The second flow channel 60 is formed between the inner cavity 11 of the body 10 and the second rotating member 30. In this way, when the cleaning robot 100 cleans the water surface, the two flow channels can increase the speed of water flow to the second rotating member 30 and increase the driving force of the second rotating member 30 on the cleaning robot 100. Even if the water flow of the first flow channel 50 decreases or even becomes blocked, it will not reduce the water supply of the drive paddle and affect the movement of the cleaning robot 100.

[0052] In some embodiments, in a direction perpendicular to the travel direction of the cleaning robot 100, the first rotating member 20 is spaced apart from the body 10 to form a first sub-flow channel 51, the second rotating member 30 is spaced apart from the body 10 to form a second sub-flow channel 52, the garbage collection port 41, the inner cavity 11 of the garbage collection device 40, and the filter hole 42 form a third sub-flow channel 53, and the first sub-flow channel 51, the third sub-flow channel 53, and the second sub-flow channel 52 are sequentially connected to form the first flow channel 50.

[0053] In other words, along the height direction of the cleaning robot 100, the first rotating member 20 is spaced apart from the body 10 to form a first sub-channel 51, and the second rotating member 30 is spaced apart from the body 10 to form a second sub-channel 52.

[0054] It should be noted that when the cleaning robot 100 cleans the water surface, the water flows in from the first sub-channel 51, enters the inner cavity 11 of the garbage collection device 40 through the garbage collection port 41, passes through the filter hole 42 (the part of the garbage collection device 40 is the third sub-channel 53), and enters the second sub-channel 52 to provide water replenishment for the second rotating component 30.

[0055] Understandably, the water flow direction in the first channel 50 is opposite to the direction of travel of the cleaning robot 100.

[0056] When the cleaning robot 100 cleans the water surface, the first rotating component 20 rotates, and a water ring is formed on the outer periphery of the first rotating component 20. The garbage flows into the garbage collection device 40 with the water flow, thereby cleaning the garbage on the water surface. In this embodiment, the first sub-flow channel 51 formed between the first rotating component 20 and the body 10 during garbage cleaning and the third sub-flow channel 53 formed by the garbage collection device 40 are used as part of the first flow channel 50, and are connected to the second sub-flow channel 52 formed by the second rotating component 30 and the body 10. This simplifies the design of the first flow channel 50, eliminates the need for additional space reserved for the first flow channel 50, reduces the size of the cleaning robot 100, and makes the structural arrangement of the cleaning robot 100 more compact and smaller.

[0057] Please refer to Figures 5 and 6 together. In some embodiments, the body 10 includes a first housing 12 and a second housing 13. The first housing 12 has a receiving groove 121 on the side opposite to the second housing 13. Along the traveling direction of the cleaning robot 100, the first rotating member 20, the garbage collection device 40, and the second rotating member 30 are sequentially arranged in the receiving groove 121. The first rotating member 20 and the bottom wall of the receiving groove 121 form a first sub-flow channel 51, and the second rotating member 30 and the bottom wall of the receiving groove 121 form a second sub-flow channel 52.

[0058] Understandably, the first rotating component 20, the garbage collection device 40, and the second rotating component 30 are all located on the side of the first housing 12 opposite to the second housing 13.

[0059] It should be noted that the first housing 12 and the second housing 13 are arranged along the height direction of the cleaning robot 100.

[0060] Optionally, the first housing 12 and the second housing 13 are detachably connected.

[0061] Understandably, the first rotating member 20 is rotatably disposed on the first housing 12, and the second rotating member 30 is rotatably disposed on the first housing 12. The first rotating member 20 and a portion of the surface of the first housing 12 facing away from the second housing 13 form the first sub-flow channel 51, and the second rotating member 30 and a portion of the surface of the first housing 12 facing away from the second housing 13 form the second sub-flow channel 52.

[0062] Understandably, the first housing 12 and the second housing 13 form the inner cavity 11 of the body 10.

[0063] In this embodiment, by making the first rotating member 20 form a first sub-channel 51 with the bottom wall of the receiving groove 121, and making the second rotating member 30 form a second sub-channel 52 with the bottom wall of the receiving groove 121, the structure of the cleaning robot 100 can be simplified. There is no need to set the first sub-channel 51 and the second sub-channel 52 separately, which simplifies the manufacturing process of the cleaning robot 100 and makes the overall structure of the cleaning robot 100 more compact, making the cleaning robot 100 more miniaturized.

[0064] Please refer again to Figures 3 and 4. In some embodiments, the inner cavity 11 of the body 10 includes an adjacent and communicable main cavity 111 and a secondary cavity 112. In the direction perpendicular to the travel direction of the cleaning robot 100, the secondary cavity 112 is spaced apart from the second rotating member 30. The side of the secondary cavity 112 facing the second rotating member 30 has an opening 113. The main cavity 111 is formed as a fourth sub-flow channel 61, and the secondary cavity 112 is formed as a fifth sub-flow channel 62. The fourth sub-flow channel 61 and the fifth sub-flow channel 62 form the second flow channel 60.

[0065] Understandably, the secondary cavity 112 and the second rotating member 30 are arranged along the height direction of the cleaning robot 100. An opening 113 is provided between the secondary cavity 112 and the second rotating member 30 to connect the secondary cavity 112 with the second sub-channel 52.

[0066] Understandably, the first housing 12 and the second housing 13 form the main cavity 111 and the secondary cavity 112.

[0067] Understandably, the first housing 12 has an opening 113 on the side facing the second rotating member 30.

[0068] Optionally, the main cavity 111 and the secondary cavity 112 are arranged along the traveling direction of the cleaning robot 100. Optionally, the fourth sub-channel 61 is connected to the third sub-channel 53 and the fifth sub-channel 62 respectively.

[0069] It should be noted that when the cleaning robot 100 is used for water surface cleaning, and the second rotating component 30 rotates, water flows from the outside of the body 10 into the fourth sub-channel 61. After passing through the fourth sub-channel 61, it enters the second sub-channel 52 through the opening 113. Furthermore, water can also directly enter the fifth sub-channel 62 from the outside, and then enter the second sub-channel 52 through the opening 113. Moreover, water entering the fourth sub-channel 61 can also first pass through the third sub-channel 53 before flowing into the second sub-channel 52.

[0070] In this embodiment, by providing a fourth sub-channel 61 and a fifth sub-channel 62 within the body 10, the water replenishment of the second rotating member 30 can be increased, thereby enhancing the driving force of the second rotating member 30 on the cleaning robot 100. Furthermore, it can also avoid the problem of insufficient driving force provided to the cleaning robot 100 due to the reduced water replenishment of the second rotating member 30 caused by blockage of the first channel 50.

[0071] In some embodiments, the secondary cavity 112 includes a first secondary cavity 1121 and a second secondary cavity 1122. A partition plate 122 is horizontally disposed between the first secondary cavity 1121 and the second secondary cavity 1122. The partition plate 122 is provided with a first through hole 1221. The opening 113 is constructed on the side of the second secondary cavity 1122 away from the partition plate 122.

[0072] Understandably, the first sub-cavity 1121, the second sub-cavity 1122, and the second rotating member 30 are arranged sequentially along the height direction. In other words, the second sub-cavity 1122 is located between the first sub-cavity 1121 and the second rotating member 30.

[0073] Optionally, the partition plate 122 is located on the first housing 12. In other words, the first housing 12 includes the partition plate 122. Furthermore, the partition plate 122 is a part of the first housing 12.

[0074] It should be noted that the first sub-cavity 1121 and the second sub-cavity 1122 are arranged along the height direction of the cleaning robot 100 to form the fifth sub-channel 62. Understandably, the fifth sub-channel 62 extends along the height direction of the cleaning robot 100. When the cleaning robot 100 is used for water surface cleaning, and the second rotating member 30 rotates, water enters from the second housing 13 side into the first sub-cavity 1121, passes sequentially through the first through hole 1221 of the partition plate 122, the second sub-cavity 1122, and the opening 113, and then flows into the second sub-channel 52.

[0075] Optionally, the first sub-cavity 1121, the second sub-cavity 1122, and the second sub-channel 52 are arranged along the height direction of the cleaning robot 100.

[0076] Optionally, the second housing 13 and the isolation plate 122 form the first sub-cavity 1121, and the second sub-cavity 1122 is formed in the first housing 12.

[0077] In this embodiment, by setting the first secondary cavity 1121 and the second secondary cavity 1122 at the position corresponding to the second rotating member 30 in the height direction of the cleaning robot 100, the internal space of the cleaning robot 100 can be better utilized, making the overall layout of the cleaning robot 100 more compact. In addition, a partition plate 122 is set between the first secondary cavity 1121 and the second secondary cavity 1122, which can increase the overall mechanical strength of the first housing 12 and the second housing 13, and facilitate the installation and connection of the first housing 12 and the second housing 13.

[0078] Please refer to Figures 6 and 7 together. In some embodiments, a second through hole 101 and a blocking member 14 are constructed on the side wall between the main cavity 111 and the secondary cavity 112. The blocking member 14 is flipped and disposed on the side wall and covers the second through hole 101. When the cleaning robot 100 is cleaning the water surface, the second through hole 101 is in the open state. When the cleaning robot 100 is cleaning underwater, the second through hole 101 is in the closed state.

[0079] Understandably, when the cleaning robot 100 is cleaning the water surface, the shielding member 14 is at least partially away from the second through hole 101 so that the second through hole 101 is open, so that the fourth sub-channel 61 is connected to the fifth sub-channel 62; when the cleaning robot 100 is cleaning underwater, the shielding member 14 closes the second through hole 101.

[0080] Optionally, the blocking member 14 is rotatably disposed on the side wall. In a specific embodiment, the end of the blocking member 14 facing away from the second rotating member 30 is rotatably connected to the side wall. It can be understood that the blocking member 14 has a connecting end 142 and a free end 141 disposed opposite to each other, the connecting end 142 is rotatably connected to the side wall, and the free end 141 is located between the connecting end 142 and the second rotating member 30.

[0081] It should be noted that the second through hole 101 is provided on the side wall between the first secondary cavity 1121 and the second secondary cavity 1122 and the main cavity 111, and the blocking member 14 is provided at the position of the second through hole 101.

[0082] Optionally, the number of the second through holes 101 can be one or more. When the number of the second through holes 101 is multiple, the multiple second through holes 101 are spaced apart.

[0083] Optionally, the number of shielding members 14 can be one or more. When there are multiple second through holes 101 and shielding members 14, the second through holes 101 and shielding members 14 correspond one-to-one. In other words, one second through hole 101 corresponds to one shielding member 14, and different second through holes 101 correspond to different shielding members 14.

[0084] Optionally, the shielding member 14 can be, but is not limited to, a silicone plate, a rubber plate, etc. When the cleaning robot 100 performs underwater cleaning, the silicone plate can fit more tightly against the side wall, thereby better sealing the second through hole 101.

[0085] In this embodiment, through the cooperation of the second through hole 101 and the shielding member 14, when the cleaning robot 100 is cleaning the water surface, the second through hole 101 is opened, so that the fourth sub-flow channel 61 and the fifth sub-flow channel 62 are connected, which can increase the water flow path of the cleaning robot 100, increase the water replenishment of the second rotating member 30, and thus improve the efficiency of water surface cleaning; in addition, when the cleaning robot 100 is cleaning underwater, the shielding member 14 closes the second through hole 101, thereby closing the main cavity 111, so as not to affect the normal operation of the main pump in the main cavity 111.

[0086] Please refer to Figures 6 and 8. In some embodiments, the cleaning robot 100 further includes a water pump assembly 70. The shielding member 14 is located in the secondary cavity 112. When the water pump assembly 70 is started, the shielding member 14 is pressed tightly against the second through hole 101 under the action of negative pressure. When the water pump assembly 70 is turned off, the shielding member 14 can open the second through hole 101 under the action of water flow.

[0087] Understandably, the shielding member 14 is located on the side of the sidewall facing away from the main cavity 111; in other words, the shielding member 14 is located on the side of the sidewall facing the secondary cavity 112.

[0088] It should be noted that the water pump assembly 70 is at least partially located within the main chamber 111. When the water pump assembly 70 is started, a negative pressure is formed within the main chamber 111.

[0089] It should be noted that the connecting end 142 of the shield 14 is located closer to the top of the cleaning robot 100 than the free end 141. Therefore, when the cleaning robot 100 is upright and performing underwater cleaning, the shield 14 will droop under the action of gravity, causing the free end 141 of the shield 14 to be close to the side wall.

[0090] In this embodiment, when the water pump assembly 70 is started, the main cavity 111 needs to be closed to form a negative pressure, so that water can enter the water pump and flow upward (towards the top of the cleaning robot 100 when it is upright). If the second through hole 101 is open at this time, it will be difficult to form a negative pressure in the main cavity 111, which will affect the normal operation of the water pump assembly 70. In this embodiment, through the cooperation of the second through hole 101 and the shielding member 14, when the cleaning robot 100 is cleaning the water surface, the second through hole 101 is opened, so that the fourth sub-flow channel 61 and the fifth sub-flow channel 62 are connected, which can increase the water flow path of the cleaning robot 100, increase the water replenishment of the second rotating member 30, and thus improve the efficiency of water surface cleaning. In addition, when the cleaning robot 100 is cleaning underwater, the shielding member 14 hangs down under the action of gravity. The negative pressure generated by the water pump assembly 70 makes the shielding member 14 only adsorbed on the side wall, thereby closing the second through hole 101. This will not affect the normal operation of the main pump in the main cavity 111.

[0091] Please refer to Figure 7 again. In some embodiments, a third through hole 131 is formed on the side of the secondary cavity 112 opposite to the opening 113.

[0092] Understandably, the third through hole 131 is provided on the side of the first secondary cavity 1121 opposite to the second secondary cavity 1122.

[0093] It can also be understood that the second housing 13 is provided with a third through hole 131 at the position corresponding to the first sub-cavity 1121, and the third through hole 131 is connected to the first sub-cavity 1121.

[0094] When the cleaning robot 100 is inverted to clean the water surface, the second rotating component 30 rotates, and the water flows from the third through hole 131 into the first secondary cavity 1121, and then flows through the first through hole 1221, the second secondary cavity 1122, and the opening 113 to the second sub-channel 52 (i.e., the second rotating component 30), thereby increasing the water supply of the first rotating component 20 and improving the driving force of the second rotating component 30 on the cleaning robot 100.

[0095] In this embodiment, by constructing a third through hole 131 on the side of the secondary cavity 112 opposite to the opening 113, the water flow rate in the fifth sub-channel 62 can be better increased, thereby increasing the water replenishment of the first rotating member 20 and increasing the driving force of the second rotating member 30 on the cleaning robot 100.

[0096] Please refer again to Figure 8. In some embodiments, the cleaning robot 100 further includes an isolation cover 123, which is disposed in the inner cavity 11 of the body 10 and has a plurality of fourth through holes 1234.

[0098] It should be noted that the isolation cover 123 forms part of the main cavity 111. The garbage collection device 40 is also provided with a mesh (not shown) at the position of the fourth through hole 1234 of the isolation cover 123, so that the main cavity 111 is connected to the inner cavity 11 of the garbage collection device 40.

The end of the third isolation sub-part 1233 away from the second isolation sub-part 1232 is connected to the receiving portion 124. The first isolation sub-part 1231, the second isolation sub-part 1232, and the third isolation sub-part 1233 are all provided with a plurality of fourth through holes 1234, and the plurality of fourth through holes 1234 are all connected to the main cavity 111.

[0100] Optionally, the first housing 12 further includes a first side portion 125 and a second side portion 126, the first side portion 125 and the second side portion 126 being disposed on the same side of the isolation plate 122 and respectively bent to connect the two ends of the isolation plate 122; the first side portion 125, the isolation plate 122 and the second side portion 126 enclose a second secondary cavity 1122 and the opening 113; one end of the second side portion 126 facing away from the isolation plate 122 is connected to one end of the first isolation sub-part 1231 facing away from the second isolation sub-part 1232 and is spaced apart from the first isolation sub-part 1231.

[0101] Understandably, the second side portion 126 has the second through hole 101.

[0102] In this embodiment, by providing a fourth through hole 1234 on the isolation cover 123, the main cavity 111 of the inner cavity 11 of the body 10 can be connected to the inner cavity 11 of the garbage collection device 40, so that the main cavity 111 can serve as a water flow channel of the water pump assembly 70 in addition to being part of the fourth sub-flow channel 61, thereby making the overall structure of the cleaning robot 100 more compact.

[0103] Optionally, the second housing 13 includes a top 132, a third side 133, and a fourth side 134. The third side 133 and the fourth side 134 are spaced apart on the side of the top 132 facing the first housing 12. The third side 133 is further away from the cleaning brush than the fourth side 134. The top 132, the third side 133, and the fourth side 134 form a first sub-cavity 1121. The top 132 has a plurality of third through holes 131 corresponding to the position of the first sub-cavity 1121. The plurality of third through holes 131 are used to connect the first sub-cavity 1121 and the side of the second housing 13 away from the first housing 12. The top 132 and the first housing 12 also form a main cavity 111. The top 132 has a through hole 135 communicating with the main cavity 111. The main cavity 111 is used to accommodate the water pump assembly 70. A portion of the water pump assembly 70 is located in the through hole 135.

[0104] Understandably, the fourth side portion 134 has the second through hole 101.

[0105] Understandably, the fourth side portion 134 and the second side portion 126 form the sidewall between the main cavity 111 and the secondary cavity 112.

[0106] Please refer to Figure 9. In some embodiments, the waste collection device 40 has an inclined surface 4411 on the side wall near the body 10 and near the waste collection port 41.

[0107] Optionally, the waste collection device 40 includes a base plate 43 and a top plate 44 arranged in a square shape opposite each other along the height of the cleaning robot 100. The top plate 44 is located between the base plate 43 and the first housing 12. The top plate 44 includes a first sub-plate 441 and a second sub-plate 442 that are bent and connected. The first sub-plate 441 is disposed near the cleaning brush, and the second sub-plate 442 is disposed near the second rotating member 30.

[0110] In this embodiment, an inclined surface 4411 is provided on the side wall of the first housing 12 of the garbage collection device 40 near the garbage collection port 41 and near the body 10. This can better prevent garbage from entering the garbage collection device 40 through the garbage collection port 41 and then flowing back to the outside of the garbage collection port 41, thus affecting the cleaning effect of the cleaning robot 100.
