Description

Technical Field

[0001] This application relates to the field of pool cleaning machine technology, and more particularly to a cleaning robot. Background Technology

[0002] Cleaning robots, with their intelligent and efficient characteristics, have gradually become an important tool for pool operation and maintenance management. Currently, during operation, the filter screen of the cleaning robot's trash can easily become clogged with algae, leaves, and other impurities, increasing flow resistance and internal pressure, leading to a decrease in water flow and velocity. This weakens the propulsion power of the main spray nozzle, and when the robot tries to climb the pool wall, it struggles to overcome gravity, resulting in weak ascent, stalling, or even slipping. Consequently, the cleaning robot cannot effectively reach and clean critical areas near the waterline, which are precisely where stains and algae tend to accumulate, creating unsanitary corners and severely impacting the overall cleaning effect. Utility Model Content

[0003] In view of this, this application provides a cleaning robot. By arranging a first liquid extraction component, a second liquid extraction component, and a detachable filter component inside the cleaning robot's cavity, the power output and posture stability of the cleaning robot when crawling on the pool wall can be effectively improved, thereby ensuring that it can reliably reach and thoroughly clean the waterline area.

[0004] In a first aspect, embodiments of this application propose a cleaning robot, which includes a body having a first cavity and a second cavity isolated from each other. The first cavity has a first water inlet and a first water outlet communicating with it, and the second cavity has a second water inlet and a second water outlet communicating with it. A first liquid extraction component is disposed in the first cavity for drawing water into the first cavity through the first water inlet and spraying it out through the first water outlet to generate an adhesion force that causes the cleaning robot to adhere to the cleaning surface. A second liquid extraction component is disposed in the second cavity for drawing water into the second cavity through the second water inlet and spraying it out through the second water outlet to generate a thrust that propels the cleaning robot to move. A filter component is disposed at the second water inlet and detachably connected to the body for filtering the water flowing into the second cavity through the second water inlet.

[0005] The cleaning robot provided in this application has a first chamber and a second chamber that are isolated from each other on its body. During operation, a first suction component draws water into the first chamber through a first inlet and sprays it out through a first outlet, generating a downward reaction force that keeps the cleaning robot in close contact with the bottom or wall of the pool, enhancing adhesion and friction. A second suction component draws water into the second chamber through a second inlet and sprays it out through a second outlet, providing the cleaning robot with the propulsion required for moving forward and climbing on horizontal or vertical surfaces. The combined effect of these two components ensures that the cleaning robot has both a stable adhesion to prevent slippage and sufficient propulsion during operation, enabling it to reliably reach and clean critical areas near the waterline, effectively eliminating blind spots. In addition, the filter components that can be detachably connected to the machine body are provided to avoid filter clogging and water flow power reduction caused by non-removable or inconvenient filter components. By regularly cleaning or disassembling and replacing the filter, the water flow power and propulsion force are kept stable, ensuring that the cleaning robot can maintain sufficient propulsion force to reach and clean the water line area for a long time. This not only improves the ease of maintenance and service life of the device, but also ensures the cleanliness of the incoming water and the long-term stable operation of the equipment.

[0006] In some embodiments, the filtration assembly includes a mounting component and a first filter screen. The mounting component is detachably connected to the body, and the mounting component has a plurality of first through holes. The first filter screen is disposed at the first through holes and connected to the mounting component. In this embodiment, by providing the first filter screen and the mounting component, the first through holes can ensure a sufficiently large flow area, and the first filter screen can ensure the filtration effect. This ensures that there is enough water flow from the second outlet to generate sufficient thrust to move the cleaning robot, while also taking into account the cleanliness of the incoming water and the long-term stable operation of the equipment.

[0007] In some embodiments, the housing is provided with a mounting groove, the second water inlet is located within the mounting groove, and the mounting component is embedded in the mounting groove. In this embodiment, by embedding the mounting component in the mounting groove, the mounting groove provides accurate positioning for the mounting component, which facilitates the assembly of the mounting component and allows the filter assembly to be stably supported on the housing. The second water inlet being located within the mounting groove makes the flow path from the outside to the second water inlet smoother, helps reduce water inlet resistance, and also allows for a tight fit between the mounting component and the housing, improving sealing performance.

[0008] In some embodiments, the mounting component is provided with a snap-fit ​​portion, and the body is provided with a snap-fit ​​groove. The mounting component and the body are connected by the snap-fit ​​engagement of the snap-fit ​​portion and the snap-fit ​​groove. In this embodiment, by providing a snap-fit ​​portion on the mounting component, and the snap-fit ​​engagement between the snap-fit ​​portion and the snap-fit ​​groove of the body, the connection between the filter assembly and the body is ensured, which helps to resist water flow impact and vibration generated during the movement of the cleaning robot, prevents the filter assembly from falling off during operation, and ensures the stability and safety of the cleaning operation.

[0009] In some embodiments, the snap-fit ​​portion includes a protruding section and a hook section connected in sequence. The inner side of the housing is provided with a snap-fit ​​post for engaging with the snap-fit ​​portion. The protruding section extends away from the mounting component and passes through the snap-fit ​​groove. The hook section is located at the end of the protruding section and extends laterally for hooking onto the snap-fit ​​post. In this embodiment, by designing the snap-fit ​​portion as a combination of a protruding section and a hook section, the protruding section provides support, and the hook-fitting action between the hook section and the snap-fit ​​post makes the connection more secure and stable, ensuring the reliability and sealing of the connection. The protruding section acts as an insertion guide, simplifying the installation process of the filter assembly, improving positioning accuracy, and enhancing the maintenance convenience of the filter assembly and the overall user experience.

[0010] In some embodiments, the mounting component is provided with a first magnetic suction element, and the body is correspondingly provided with a second magnetic suction element. The mounting component and the body are connected by the magnetic attraction of the first and second magnetic suction elements. In this embodiment, the mounting component is fixed to the body by the magnetic attraction of the first and second magnetic suction elements, which simplifies the installation process and improves ease of use. Furthermore, the magnetic connection avoids wear caused by mechanical connections, which helps maintain stable connection performance over a long period, reduces the risk of aging and damage to the filter components due to maintenance and disassembly, extends the service life of the filter components and the body, and reduces maintenance costs.

[0011] In some embodiments, the first water outlet is located at the top of the body, and the second water outlet is located at the rear of the body. The water outlet direction of the second water outlet is opposite to the direction of travel of the cleaning robot. In this embodiment, by providing a second water outlet and a second liquid extraction component at the rear, even in cases where the cleaning robot's trash can is clogged or the main water pump flow rate decreases, the jet of water from the second water outlet at the rear can still provide additional wall-climbing power. This ensures that the cleaning robot has sufficient power to reliably reach and clean the waterline area, effectively eliminating sanitary dead corners and achieving comprehensive cleaning of the pool bottom, walls, and waterline area.

[0012] In some embodiments, the cleaning robot further includes a waste collection component and a motor housing component. A first liquid extraction component is partially disposed within the sealed cavity of the motor housing component, and the waste collection component is disposed within the first cavity and located between the second liquid extraction component and the motor housing component. In this embodiment, the waste collection component and the motor housing component are integrated into the body, optimizing the internal space utilization and making the overall structure more compact. The sealed cavity of the motor housing component helps protect the first motor, ensuring waterproofing and guaranteeing the operational reliability of the first liquid extraction component. The waste collection component efficiently collects waste from the filtered water path, and its detachable connection to the body facilitates regular removal and cleaning, greatly simplifying the maintenance process.

[0013] In some embodiments, the waste collection assembly includes a waste bin, a shield, and a second filter. The bottom of the waste bin has a suction port, the shield is movably disposed at the suction port, and the side wall of the waste bin has several openings. The second filter is disposed at one of the openings and connected to the side wall of the waste bin. In this embodiment, by providing a waste bin, a shield, and a second filter, and with the side wall of the waste bin having several openings and the second filter being disposed at one of the openings and connected to the side wall of the waste bin, water enters the waste bin, is filtered by the second filter, and flows out through the openings in the side wall of the waste bin, thereby achieving waste collection and ensuring high filtration efficiency.

[0014] In some embodiments, the body includes a bottom shell, a middle shell, and a partition. The partition divides the internal space of the bottom shell into a first cavity and a second cavity. The middle shell covers the bottom shell and the partition to isolate the first cavity and the second cavity from each other. In this embodiment, by using a bottom shell, a middle shell, and a partition to divide the internal space of the housing into zones, the first and second liquid extraction components operate stably and efficiently under their respective working conditions, improving the sealing of the internal space of the body. Furthermore, during the assembly and maintenance of the cleaning robot, maintenance operations can be performed in zones, making production more convenient and facilitating subsequent maintenance and replacement.

[0024] The possible embodiments of this application are described below with reference to the accompanying drawings.

[0025] Currently, when cleaning robots are working, their dustbins are prone to clogging with algae, leaves, and other impurities during the filtration process. This increases flow resistance and internal pressure, leading to a decrease in water flow and velocity. Consequently, the propulsion power of the main spray nozzles weakens, and the robot struggles to overcome gravity when climbing the pool walls, resulting in weak ascent, stalling, or even slipping. Therefore, the cleaning robot cannot effectively reach and clean critical areas near the waterline, which are precisely where dirt and algae tend to accumulate, creating unsanitary corners and severely impacting the overall cleaning effect.

[0026] Figure 1 This is a structural schematic diagram of the cleaning robot provided in an embodiment of this application. (In conjunction with...) Figure 1 As shown, in some embodiments, the cleaning robot 10 may include a body 100, a first liquid extraction assembly 11, a second liquid extraction assembly 12, and a filter assembly 13. The first liquid extraction assembly 11, the second liquid extraction assembly 12, and the filter assembly 13 are all located inside the body 100. The first liquid extraction assembly 11 and the second liquid extraction assembly can be used to extract liquid to be cleaned from outside the body 100, such as water from a swimming pool, into the body 100 or into the filter assembly 13 of the body 100. The filter assembly 13 can be used to filter the liquid to be cleaned and collect particulate contaminants removed from the liquid to be cleaned.

[0027] Continue to combine Figure 1As shown, the body 100 has a first cavity 110 and a second cavity 120 that are isolated from each other. The first cavity 110 and the second cavity 120 are independent of each other. The water flow inside the first cavity 110 and the second cavity 120 will not interfere with each other. The first cavity 110 and the second cavity 120 can operate independently under different working conditions. The first cavity 110 has a first inlet 111 and a first outlet 112 connected thereto. The first liquid extraction assembly 11 is disposed inside the first cavity 110. When the first liquid extraction assembly 11 is working, it draws water into the first cavity 110 through the first inlet 111 and sprays it out through the first outlet 112. The water flow from the first outlet 112 is downward, that is, the water flow from the first outlet 112 can generate a downward reaction force. This water flow makes the cleaning robot 10 form a low-pressure zone between itself and the bottom or wall of the pool during the working process, generating a strong adhesion force, so that the cleaning robot 10 is kept in close contact with the bottom or wall of the pool, enhancing the adsorption force and friction force.

[0028] Continue to combine Figure 1 As shown, the second cavity 120 has a second inlet 121 and a second outlet 122 connected thereto. The second pumping assembly 12 is disposed inside the second cavity 120. When the second pumping assembly 12 is working, the water sucked in by the second pumping assembly 12 through the second inlet 121 can pass through the filter assembly 13, where algae, leaves, and other debris can be trapped and filtered. The filtered water enters the second cavity 120 and is sprayed out through the second outlet 122. The water flow direction sprayed out of the second outlet 122 is opposite to the traveling direction of the cleaning robot 10, thereby generating a reverse thrust on the cleaning robot 10, providing the necessary propulsion for the cleaning robot 10 to move forward or climb on a horizontal or vertical plane.

[0029] Continue to combine Figure 1 As shown in the embodiment of this application, the cleaning robot 10 includes a filter assembly 13, which is disposed at the second water inlet 121 to ensure that the water drawn in by the second water inlet 121 can pass through the filter assembly 13 for filtration before flowing into the second cavity 120. The filter assembly 13 is detachably connected to the body 100. When the filter assembly 13 is worn or clogged due to the interception of impurities, it can be easily removed from the body 100 for cleaning or replacement and then reinstalled. This simple operation reduces labor costs and extends the service life of the cleaning robot 10, ensuring the cleanliness of the incoming water and the long-term stable operation of the cleaning robot 10.

[0030] In this embodiment, by providing mutually isolated first cavities 110 and second cavities 120 on the body 100, the first cavities 110 and second cavities 120 have independent working states. During the operation of the cleaning robot 10, the first suction component 11 can draw water into the first cavity 110 through the first inlet 111 and spray it out through the first outlet 112. The water flow sprayed out of the first outlet 112 can generate a downward reaction force, keeping the cleaning robot 10 in close contact with the bottom or wall of the pool, enhancing the adsorption and friction. The second suction component 12 draws water into the second cavity 120 through the filter component 13 and sprays it out through the second outlet 122, providing the cleaning robot 10 with the propulsion required for moving forward and climbing on a horizontal or vertical plane, and the first suction component 11 is not affected by the clogging of the filter component 13. The combined effect of these two factors ensures that the cleaning robot 10 has both a stable grip to prevent slippage during operation and sufficient propulsion to reliably reach and clean key areas near the waterline, effectively eliminating blind spots. Furthermore, the inclusion of a detachable filter assembly 13, which is connected to the body 100, prevents filter clogging and reduced water flow power caused by non-removable or inconvenient filter assembly 13. Regular cleaning or replacement of the filter maintains stable water flow power and propulsion, ensuring that the cleaning robot 10 can maintain sufficient propulsion to reach and clean the waterline area over a long period. This not only improves the ease of maintenance and lifespan of the device but also ensures the cleanliness of the incoming water and the long-term stable operation of the equipment.

[0031] Figure 2 This is a partial structural schematic diagram of the cleaning robot provided in an embodiment of this application. Figure 3 This is a partial structural diagram of a cleaning robot without a filter assembly provided in an embodiment of this application. Figure 4 This is a schematic diagram of the structure of the filtering component provided in an embodiment of this application. (In conjunction with...) Figure 2 , Figure 3 and Figure 4As shown, in one possible implementation, the filter assembly 13 includes a mounting member 131 and a first filter screen (not shown). The mounting member 131 is detachably connected to the body 100. The mounting member 131 serves as the skeleton of the filter assembly 13 and can be detachably connected to the second water inlet 121 on the body 100 via snap-fit, thread, or magnetic attraction. The mounting member 131 has several first through holes 132, which serve as the main channels for water flow. The multiple first through holes 132 are of different sizes and are arranged on the mounting member 131. The first filter screen is located at the first through holes 132 and connected to the mounting member 131. The first filter screen covers and is fixed to the first through holes 132 to intercept impurities such as algae and leaves. During operation, the second liquid extraction assembly 12 carries impurities to the second water inlet 121. The first filter screen filters the flowing water, blocking the impurities outside the first filter screen. When cleaning the filter assembly 13, simply rinse or brush the surface of the first filter screen to quickly remove attached impurities or dirt; the operation is convenient.

[0032] In this embodiment, by setting a first filter screen and mounting component 131, multiple first through holes 132 can ensure a sufficiently large flow area, and the first filter screen can ensure the filtration effect, thereby protecting the second liquid extraction component 12. Furthermore, when maintaining the filter component, simply rinsing or brushing the surface of the first filter screen can quickly remove attached impurities or dirt, preventing impurities from accumulating in dead corners, avoiding cumbersome operations, reducing the risk of damage to the first filter screen, better ensuring filtration efficiency, and extending the service life of the filter component 13.

[0033] Combination Figure 2 , Figure 3 and Figure 4 As shown, in one possible embodiment, the body 100 is provided with a mounting groove 101, the second water inlet 121 is located within the mounting groove 101, and the mounting member 131 is embedded in the mounting groove 101. The mounting groove 101 is provided on the body 100, and its shape is adapted to the shape of the mounting member 131 of the filter assembly 13. The second water inlet 121 is located at the bottom of the mounting groove 101. When the filter assembly 13 is installed, the mounting member 131 can be embedded in the mounting groove 101, thereby fixing the filter assembly 13. The mounting member 131 can be embedded in the mounting groove 101 by means of snaps, threads, or magnetic attraction. The mounting groove 101 provides limitation and support for the mounting member 131, ensuring the stability of the mounting member 131 when water flows through it, making it difficult for the mounting member 131 to shift or loosen.

[0034] In this embodiment, by providing a mounting groove 101, the mounting component 131 is embedded in the mounting groove 101. The mounting groove 101 provides accurate positioning for the mounting component 131, which is beneficial for the assembly of the mounting component 131 and allows the filter assembly 13 to be stably supported on the body 100. At the same time, the second water inlet 121 is located inside the mounting groove 101, making the flow path from the outside to the second water inlet 121 smoother, which helps to reduce water inlet resistance and also allows the mounting component 131 to form a tight fit with the body 100, improving the sealing performance.

[0035] Combination Figure 2 , Figure 3 and Figure 4 As shown, in one possible embodiment, the mounting member 131 is provided with a snap-fit ​​portion 133, and the body 100 is provided with a snap-fit ​​groove 102. The mounting member 131 and the body 100 are connected by the snap-fit ​​engagement of the snap-fit ​​portion 133 and the snap-fit ​​groove 102. The mounting member 131 is provided with a snap-fit ​​portion 133, which extends in a direction away from the mounting member 131 and protrudes outward. The number of snap-fit ​​portions 133 includes multiple snap-fit ​​portions 133, which are arranged around multiple first through holes 132. The body 100 is provided with a snap-fit ​​groove 102, the position of which corresponds to the position of the snap-fit ​​part 133. When installing the filter assembly 13, simply align the snap-fit ​​part 133 on the mounting part 131 with the snap-fit ​​groove 102 on the body 100. The snap-fit ​​part 133 can be inserted into the snap-fit ​​groove 102. The mounting part 131 and the body 100 are connected by the snap-fit ​​engagement of the snap-fit ​​part 133 and the snap-fit ​​groove 102, thus fixing the filter assembly 13 to the body 100. When disassembling, maintaining, or replacing the filter assembly 13, it can be removed simply by manual operation, making the operation convenient. In one possible embodiment, the engagement structure between the snap-fit ​​part 133 and the snap-fit ​​groove 102 can adopt an elastic snap-fit ​​structure or a sliding snap-fit ​​structure.

[0036] In this embodiment, by providing a snap-fit ​​part 133 on the mounting part 131, the snap-fit ​​part 133 engages with the snap-fit ​​groove 102 of the body 100, ensuring the stable connection between the filter assembly 13 and the body 100. The tight fit between the snap-fit ​​part 133 and the snap-fit ​​groove 102 helps resist water flow impact and vibration generated during the movement of the cleaning robot 10, preventing the filter assembly 13 from falling off during operation and ensuring the stability and safety of the cleaning work. Furthermore, the filter assembly 13 can be removed from the body 100 by simple manual operation without the need for additional tools, which not only improves the convenience of installing and removing the filter assembly 13, but also helps reduce maintenance costs and improve the overall usability and reliability of the equipment.

[0037] Figure 5 This is a schematic diagram of the filtering component provided in an embodiment of this application from another perspective. Combined with... Figure 4 and Figure 5 As shown, in one possible implementation, the snap-fit ​​portion 133 includes a protruding section 1331 and a hook section 1332 connected in sequence. Each snap-fit ​​portion 133 is provided with a protruding section 1331 and a hook section 1332 connected in sequence. The hook section 1332 is located at the end of the protruding section 1331 and bends inward at a certain angle. The inner side of the body 100 is provided with a snap-fit ​​post 103 for engaging with the snap-fit ​​part 133. A protruding section 1331 extends away from the mounting part 131 and passes through the snap-fit ​​groove 102. A hook section 1332 is provided at the end of the protruding section 1331 and extends laterally for hooking onto the snap-fit ​​post 103. The protruding section 1331 can be guided and inserted into the snap-fit ​​groove 102 first. Subsequently, the hook section 1332 and the snap-fit ​​post 103 can reliably engage. The hook section 1332 is firmly hooked onto the snap-fit ​​post 103, thereby fixing the filter assembly 13 to the body 100. When disassembling or replacing the filter assembly, simply press or move the filter assembly 13 to apply a force that causes the hook section 1332 to elastically deform, causing the hook section 1332 to detach from the snap-fit ​​post, and the filter assembly 13 can be removed.

[0038] In this embodiment, the snap-fit ​​portion 133 is designed as a combination of a protruding section 1331 and a hook section 1332. The protruding section 1331 provides a certain degree of support, and the hook section 1332, in conjunction with the snap-fit ​​post 103, makes the connection more secure and stable, ensuring the reliability and sealing of the connection. The protruding section 1331 serves as an insertion guide, making the installation process of the filter assembly 13 simpler and the positioning more accurate, thus improving the maintenance convenience of the filter assembly 13 and the overall user experience.

[0039] Figure 6 This is a partial structural schematic diagram of the cleaning robot provided in an embodiment of this application from another perspective. Combined with... Figure 5 and Figure 6As shown, in one possible implementation, a first magnetic suction member 134 is provided on the mounting member 131. The first magnetic suction member 134 is positioned opposite to the mounting member 131. The number of first magnetic suction members 134 can be one or more, and multiple first magnetic suction members 134 can be arranged around multiple first through holes 132. A corresponding second magnetic suction member 104 is provided on the body 100. The second magnetic suction member 104 is arranged around the second water inlet 121, and the number and position of the second magnetic suction member 104 correspond to the first magnetic suction member 134. The mounting member 131 and the body 100 are connected by the magnetic attraction of the first magnetic suction member 134 and the second magnetic suction member 104. There is a certain magnetic attraction between the first magnetic suction member 134 and the second magnetic suction member 104, which can guide the mounting member 131 to be attracted and installed on the body, thereby realizing the installation and positioning of the filter assembly 13 and firmly fixing the filter assembly 13 to the body. The whole process requires no tools, is simple to operate, and is convenient to maintain. In one possible implementation, the first magnetic attractor 134 and the second magnetic attractor 104 can be permanent magnets or other magnetic materials such as ferromagnetic metal sheets.

[0040] In this embodiment, the mounting component 131 is fixed to the body by the magnetic attraction between the first magnetic component 134 and the second magnetic component 104, which simplifies the installation process and improves ease of use. Furthermore, the magnetic connection avoids wear caused by mechanical connections, which helps maintain stable connection performance over a long period, reduces the risk of aging and damage to the filter assembly 13 due to maintenance and disassembly, extends the service life of the filter assembly 13 and the body 100, and lowers maintenance costs.

[0041] Combination Figure 1 and Figure 2 As shown, in one possible implementation, a first water outlet 112 is located at the top of the body 100, and a second water outlet 122 is located at the tail of the body 100. The body 100 includes two oppositely disposed ends. The first water outlet 112 is located at the top of the body 100 and communicates with the first cavity 110. When the first liquid extraction assembly 11 is working, water is sprayed vertically upward from the top of the body 100, using the downward reaction force to keep the cleaning robot 10 in close contact with the pool wall or bottom. The water outlet 122 flows in the opposite direction to the travel direction of the cleaning robot 10. The second water outlet 122 is located at the tail of the body 100 and communicates with the second cavity 120. When the second liquid extraction assembly 12 is working, water is sprayed from the tail of the body 100, and the water outlet direction is opposite to the travel direction of the cleaning robot 10, providing efficient forward propulsion.

[0042] In this embodiment, by setting a second water outlet 122 and a second liquid extraction component 12 at the tail, even if the trash can of the cleaning robot 10 is clogged or the main water pump flow rate decreases, the second water outlet 122 at the tail can still provide additional wall-climbing power, ensuring that the cleaning robot 10 has sufficient power to reliably reach and clean the waterline area, effectively eliminating sanitary dead corners and achieving comprehensive cleaning of the pool bottom, walls and waterline area.

[0043] Figure 7 This is a schematic diagram of the structure of the waste collection component provided in an embodiment of this application. (In conjunction with...) Figure 1 and Figure 7 As shown, in one possible implementation, the cleaning robot 10 further includes a waste collection component 14 and a motor housing component 15, which are integrated together within the body 100. A first liquid extraction component 11 is partially disposed within the sealed cavity 151 of the motor housing component 15. The first liquid extraction component 11 includes a first impeller and a first motor 113. The first motor 113 can drive the first impeller to rotate, thereby driving the first liquid extraction component 11 to perform liquid extraction. The first motor 113 of the first liquid extraction component 11 is sealed within the sealed cavity 151 of the motor housing component 15, ensuring that the first motor 113 is isolated from the water. The waste collection component 14 is disposed within the first cavity 110 and located between the second liquid extraction component 12 and the motor box component 15. The waste collection component 14 can be a garbage bag, garbage box, or garbage bin, etc. The waste collection component 14 can be detachably disposed within the first cavity 110. The waste collection component 14 is located between the second liquid extraction component 12 and the motor box component 15. When the second liquid extraction component 12 is working, the sewage sucked in and filtered can be efficiently collected in the waste collection component 14.

[0044] In this embodiment, by integrating the waste collection assembly 14 and the motor housing assembly 15 together within the body 100, the internal space utilization of the body 100 is optimized, making the overall structure more compact. The sealed cavity 151 of the motor housing assembly 15 helps protect the first motor 113 of the first liquid extraction assembly 11, ensuring waterproofing and the operational reliability of the first liquid extraction assembly 11. The waste collection assembly 14 can efficiently collect waste from the filtered water path, and the waste collection assembly 14 is detachably connected to the body 100, facilitating regular removal and cleaning, greatly simplifying the maintenance process.

[0045] Combination Figure 7As shown, in one possible implementation, the waste collection assembly 14 includes a waste bin 141, a shield 142, and a second filter (not shown). The bottom of the waste bin 141 has a suction port 1411, which can suck in water containing waste. The shield 142 is movably disposed at the suction port 1411 and can be a baffle or similar device, having an open and closed state. When the second suction assembly 12 is working, the shield 142 is in the open state, allowing waste to enter the waste bin 141 with the water flow. When the second suction assembly 12 stops working, the shield 142 automatically returns to the closed state, preventing the collected waste from leaking out and causing secondary pollution to the external environment. The side wall of the trash can 141 is provided with several openings 1412. A second filter screen (not shown) is provided at the openings 1412 and connected to the side wall of the trash can 141. After water enters the trash can 141, it is filtered by the second filter screen and flows out from the openings on the side wall of the trash can 141, thereby realizing the collection of waste and ensuring high filtration efficiency.

[0046] The trash can 141 can be detachably connected to the body 100. When maintaining or replacing it, you only need to take out the trash can 141 for cleaning, which makes maintenance more convenient and reduces maintenance costs.

[0047] Combination Figure 1 and Figure 2 As shown, in one possible embodiment, the body 100 includes a bottom shell 130, a middle shell (not shown), and a partition 140, which together form the internal space of the body 100. The partition 140 divides the internal space of the bottom shell 130 into a first cavity 110 and a second cavity 120. The partition 140 can be fixed inside the bottom shell 130 by means of snaps, screws, or other connections. The middle shell covers the bottom shell 130 and the partition 140, and the middle shell can fit tightly against the partition 140. The first cavity 110 and the second cavity 120 can be isolated from each other through sealing or welding processes. The first cavity 110 and the second cavity 120 can be completely independent and have good sealing performance, providing an independent working environment for the first liquid extraction assembly 11 and the second liquid extraction assembly 12, preventing mutual interference of water flow between the first liquid extraction assembly 11 and the second liquid extraction assembly 12, and ensuring independent operation of the two under different working conditions.

[0048] In this embodiment, by using a bottom shell 130, a middle shell, and a separator 140 to divide the internal space of the housing into sections, the first liquid extraction assembly 11 and the second liquid extraction assembly 12 are ensured to operate stably and efficiently under their respective working conditions, thus improving the sealing of the internal space of the machine. Furthermore, during the assembly and maintenance of the cleaning robot 10, maintenance operations can be performed in sections, making production more convenient and facilitating subsequent maintenance and replacement.
