[0050] The underwater cleaning assembly 1 further includes a shielding cover 18, a filter plate 19, and a connecting pipe 20. A shielding cover 18 is fixedly connected to the bottom of the fixed cross plate 11. The shielding cover 18 wraps a plurality of cleaning brushes 14. A filter plate 19 is fixedly connected to one side of the inside of the shielding cover 18. A plurality of through holes are formed in the top of the filter plate 19. A connecting pipe 20 is fixedly connected to the outside of the side of the shielding cover 18 close to the filter plate 19. The connecting pipe 20 is communicated with the inside of the shielding cover 18. One side of the connecting pipe 20 away from the shielding cover 18 is detachably connected to one end of the bottom of the composite connecting pipe 3.

[0051] The water filtration assembly 2 includes a floating plate 21, a power supply module 22, and a communication antenna 23. A square reserved groove is formed in the inside of the floating plate 21. A power supply module 22 is fixedly connected to the inside of the square reserved groove. Two ends of the top of the power supply module 22 are fixedly connected with a communication antenna 23 respectively.

[0052] The water filtration component 2 further includes a shunt pipe 24, a sewage pump 25, a water inlet 26, and a filter cartridge 27. The shunt pipe 24 is fixedly connected to the inner side of the square reserved groove, and the shunt pipe 24 is arranged at the bottom of the power supply module 22. The sewage pump 25 is fixedly connected to the center position at the bottom of the shunt pipe 24. One end at the top of the sewage pump 25 and the compound connecting pipe 3 are detachably connected. The bottom of each of the four end feet of the shunt pipe 24 is fixedly connected with a water inlet 26, and the shunt pipe 24, the sewage pump 25, and the water inlet 26 are connected in communication. A filter cartridge 27 is arranged at the bottom of each water inlet 26. The detachable component 4 is located between the water inlet 26 and the filter cartridge 27, and the detachable component 4 plays a role in facilitating the connection between the water inlet 26 and the filter cartridge 27.

[0053] Specifically: A wireless remote controller of model F21-E1 B is arranged inside the housing 5. Through the controller, the first propulsion paddle 8 can be controlled to start, and the housing 5 can be pushed to move in the water. At the same time, the moving module 7 can be controlled to adjust the direction, so as to achieve the effect of precise movement, and further improve the working efficiency of underwater cleaning.

[0054] After the housing 5 moves to a suitable position, by starting the motor 17, one of the linkage rods 13 can be driven to move. At this time, the bottom of the linkage rod 13 will drive the corresponding cleaning brush 14 to move synchronously. While the linkage rod 13 rotates, the gear 16 corresponding to the linkage rod 13 can be driven to rotate synchronously, so as to drive the gear 16 meshed with the gear 16 to rotate synchronously. Through the setting that multiple gears 16 are meshed with each other, multiple linkage rods 13 can be driven to rotate synchronously, so as to drive the cleaning brushes 14 at the bottom to rotate synchronously, and further achieve the effect of scraping and cleaning the surface of the water bottom.

[0055] At the same time, when the linkage rods 13 at both ends rotate, the second propulsion paddles 15 at the top can be driven to rotate synchronously. Through the agitation of the water by the second propulsion paddles 15, a downward pushing force can be applied to the housing 5, so that the housing 5 can be more stably attached to the water bottom surface, avoiding the housing 5 floating in the water during the cleaning process. At the same time, this setting can also press the housing 5 against the side wall of the pool when the side wall of the pool needs to be cleaned by pushing the water flow, so as to further improve the cleaning range in the water, and further improve the practicability of the device.

[0056] At this time, by turning on the sewage pump 25, suction can be generated inside the composite connecting pipe 3, and the water in the area scraped by the multiple cleaning brushes 14 can be absorbed through the connecting pipe 20 connected to the composite connecting pipe 3. Through the setting of the shielding cover 18, it is possible to reduce the influence of the dirt and impurities scraped by the cleaning brushes 14 floating randomly in the water on the absorption of the composite connecting pipe 3. Through the setting of the filter plate 19, it is possible to intercept larger stones or other hard objects in the water, so as to avoid larger stones or hard objects in the water from entering the inside of the composite connecting pipe 3 and causing blockage to the composite connecting pipe 3, or entering the inside of the sewage pump 25 and affecting the use of the sewage pump 25;

[0057] After the sewage is sucked into the inside of the sewage pump 25 through the inside of the composite connecting pipe 3, it can be discharged into the inside of the shunt pipe 24 through the top of the sewage pump 25, and the sewage is shunted through the shunt pipe 24, and synchronously passes through the inside of the water inlet 26 and accumulates inside the filter cylinder 27. Through the setting of the filter cylinder 27, it is possible to filter the incoming sewage, so as to intercept filterable impurities, etc., and discharge the filtered water, so as to achieve the effect of cleaning the water;

[0058] Through the setting of shunting through the shunt pipe 24 and the four water inlets 26, it is possible to filter more sewage at the same time and improve the effect of filtering sewage.

[0059] Embodiment 3:

[0060] This Embodiment 3 is used to further disclose the specific structure of the detachable component 4 on the premise of the above embodiments. Through the cooperation of the detachable component 4 and the structure in the above embodiments, it is possible to conveniently disassemble the filtering part, so as to improve the removal of residual impurities inside the filtering part by the staff, and further improve the underwater cleaning effect, and at the same time reduce the work intensity of the staff.

[0061] Further optimize the underwater cleaning robot provided in Embodiment 1 and Embodiment 2. Specifically, as Figures 10 - 12 shown, the detachable component 4 includes a first fixing ring 28, a second fixing ring 29 and a movable pressing ring 30. The bottom of the water inlet 26 is fixedly connected to the first fixing ring 28, the top of the filter cylinder 27 is fixedly connected to the second fixing ring 29, the outer peripheral side of the top of the second fixing ring 29 is inclined, the second fixing ring 29 and the first fixing ring 28 are arranged in a plug-in fit, an activity groove is opened on the outer peripheral side of the top of the second fixing ring 29, the movable pressing ring 30 is slidably connected inside the activity groove, and the outer peripheral side of the bottom of the movable pressing ring 30 is inclined.

[0062] The detachable component 4 further includes a fixed right-angle plate 31, a sliding rod 32, a limiting piece 33, a plug 34 and a spring 35. A plurality of fixed right-angle plates 31 are fixedly connected to the outer peripheral side of the first fixing ring 28. The sliding rod 32 is slidably connected to the inner side of the bottom of the fixed right-angle plate 31. Limiting pieces 33 are fixedly connected to the ends of the sliding rods 32 away from the first fixing ring 28. Plugs 34 are fixedly connected to the ends of the sliding rods 32 close to the first fixing ring 28, and the bottom of the end of the plug 34 close to the first fixing ring 28 is inclined. The ends of the plugs 34 away from the sliding rods 32 all penetrate through the side wall of the first fixing ring 28, and the plugs 34 are all slidably connected to the side wall of the first fixing ring 28. Springs 35 are arranged on the outer sides of the sliding rods 32. The springs 35 are located between the plugs 34 and the fixed right-angle plates 31, and the two ends of the springs 35 are fixedly connected to the plugs 34 and the fixed right-angle plates 31 respectively.

[0063] Specifically: When installing the filter cartridge 27, the filter cartridge 27 can be inserted into the inner side of the first fixing ring 28. At this time, the second fixing ring 29 at the top of the filter cartridge 27 will be inserted into the inner side of the first fixing ring 28. Due to the inclined setting of the top of the second fixing ring 29 and the inclined setting of the bottom of the plug 34, the plug 34 can be extruded towards the outer side of the first fixing ring 28. When the second fixing ring 29 continues to move upward and drives the movable groove to move to a position corresponding to the plug 34, through the extrusion cooperation of the spring 35 on the plug 34, the plug 34 can be driven towards a position closer to the center of the first fixing ring 28 again. At this time, the plug 34 will be inserted into the inner side of the movable groove. At the same time, due to the flat setting of the top of the plug 34 and the flat setting of the top of the inner side of the movable groove, the position of the second fixing ring 29 can be limited, preventing the second fixing ring 29 from detaching from the inner side of the first fixing ring 28 during use;

[0064] At this time, the plug 34 is located above the movable extrusion ring 30. Due to the gravity of the movable extrusion ring 30, it will be located at the bottom of the inner side of the movable groove and does not contact the plug 34;

[0065] When the dirt and impurities in the filter cartridge 27 accumulate too much and need to be disassembled and cleaned, the filter cartridge 27 can be driven upward. At this time, the filter cartridge 27 will drive the second fixing ring 29 to move upward synchronously, and the second fixing ring 29 will move upward inside the first fixing ring 28;

[0066] Due to the inclined setting of the bottom of the plug 34, it can cooperate with the movable extrusion ring 30 to be extruded. While the second fixing ring 29 drives the movable extrusion ring 30 to move upward, the plug 34 can be extruded towards the outer side of the first fixing ring 28. After the second fixing ring 29 drives the movable extrusion ring 30 to move to the top of the plug 34, the filter cartridge 27 can be dragged downward. At this time, the plug 34 will drive the movable extrusion ring 30 to move to the top of the inner side of the movable groove, and at the same time, the inclined surface at the bottom of the plug 34 will contact the top of the plug 34;

[0067] Through the inclined setting at the bottom of the insertion block 34, the insertion block 34 can be extruded outward again from the first fixing ring 28. When the filter cartridge 27 is pulled downward, the movable extrusion ring 30 is located at the top inside the movable groove. At this time, the movable extrusion ring 30 will extrude the insertion block 34 out of the inside of the movable groove, so that the limiting effect of the insertion block 34 inserted into the inside of the movable groove on the second fixing ring 29 can be cancelled.
