Description

Technical Field

[0001] This invention relates to the field of trash can cleaning technology, and in particular to an intelligent trash can cleaning robot. Background Technology

[0002] Currently, across China and globally, most garbage bins are cleaned manually with high-pressure water jets, or using large-scale, assembly-line equipment, or cleaning equipment that accompanies garbage trucks. These methods are larger and more expensive than existing garbage transfer vehicles, making them unsuitable for residential areas. Manual high-pressure cleaning consumes a large amount of water, requires a large area, and is very labor-intensive. In a typical small to medium-sized residential area, there are usually around 100 garbage bins. Relying on manual washing is extremely labor-intensive and consumes a lot of water. Furthermore, the cleaning process cannot automatically adjust to the amount of dirt inside the garbage bins, resulting in a low level of automation and intelligence. Therefore, we propose providing an intelligent bin-washing robot. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an intelligent drum washing robot.

[0004] The present invention adopts the following technical solution: An intelligent drum washing robot includes a main frame. A tilting assembly, an outer brush assembly, and a central brush assembly are fixedly mounted on the main frame. A water spraying assembly is also fixedly mounted on the main frame. The central brushing assembly includes a central tube rotatably mounted within the main frame. The central tube is connected to the water spraying assembly via a water pipe. A central plate is fixedly mounted on the central tube. A movable plate is slidably mounted on the central plate. An inner wall brush is fixedly mounted on the movable plate. A four-way pipe is fixedly mounted on the central tube. Two output ends of the four-way pipe are fixedly connected to flexible hoses, and these flexible hoses are fixedly connected to rotating pipes. A control component is fixedly installed inside the central plate. This control component can automatically adjust the spray range of the rotating pipe according to the position of the inner wall brush inside the trash can. The control component includes a displacement encoder, a moving component, and a positioning component. The displacement encoder is fixedly installed on the outside of the center plate. The positioning component can determine the rotation point of the rotating tube. The moving component can make the rotating tube rotate back and forth around the rotation point. The displacement encoder can adjust the amplitude of the rotation of the rotating tube. The moving component drives the moving plate to move back and forth through a buffer component. The buffer component can drive the positioning component to move and change the rotation point.

[0005] Preferably, the moving component includes a first hydraulic cylinder fixedly installed inside the center plate, a moving frame sleeved on the outside of the rotating tube, connecting plates fixedly connected to both sides of the moving frame, a buffer component and connecting plates fixedly connected, and the output end of the first hydraulic cylinder and the buffer component fixedly connected.

[0006] Preferably, the positioning assembly includes a control ring slidably sleeved on the outside of the rotating tube, a control frame rotatably connected to the outside of the control ring, the control frame and the center plate being slidably connected, a second hydraulic cylinder being fixedly installed inside the center plate, and the output ends of the control frame and the second hydraulic cylinder being fixedly connected.

[0007] Preferably, the buffer assembly includes multiple fixed clamps fixedly installed on the upper side of the connecting plate. The multiple fixed clamps are grouped in pairs, and the position and number of the fixed clamps in each group are opposite to the moving plate. A fixed rod is fixedly connected between each group of fixed clamps. A sleeve is slidably sleeved on the outside of the fixed rod. A buffer spring is fixedly connected between the sleeve and the fixed clamp. A square rod is slidably connected to the sleeve. The square rod is fixedly connected to the moving plate. A touch switch is fixedly connected to the side wall of the fixed clamp.

[0008] Preferably, a manifold assembly is fixedly installed on the outside of the control frame. The manifold assembly can increase the pressure of the cleaning water sprayed from the rotating pipe, improve the penetration, and enhance the cleaning effect on the rounded corners of the trash can.

[0009] Preferably, the manifold assembly includes two square plates slidably mounted on the end of the rotating tube. A limiting frame is fixedly connected to the outside of the rotating tube. A limiting groove is opened on the side wall of the limiting frame. A limiting rod is slidably connected in the limiting groove. A limiting plate is rotatably connected to the outside of the limiting rod. The limiting plate is rotatably connected to a control ring. A movable clamping plate is fixedly connected to the outside of the limiting rod. The movable clamping plate is fixedly connected to the square plate.

[0010] Preferably, a groove is formed on one side of the square plate, a diverter plate is rotatably connected in the groove, and a compression spring is fixedly connected between the diverter plate and the square plate.

[0011] Preferably, a round rod is fixedly connected to the outer side of the diverter plate, and multiple protrusions are uniformly fixedly connected to the side wall of the limiting frame.

[0012] The beneficial effects of this invention are: 1. First, it occupies a small area. The equipment is 2.4 meters long, 1.4 meters wide, and 2.2 meters high, occupying an area of ​​only 3.36 square meters. 2. Low noise: The main frame is made of carbon steel sheet, laser-cut, CNC bending, welding, and powder coating. It is equipped with an automatic control silent tubular motor high-speed rolling door. The interior uses soft brushes and is controlled by a motor to rotate at high speed. The internal mechanical structure automatically flips and transports the garbage can in and out. During the flipping process, water is automatically sprayed to wash and brush the inner wall, bottom and outside of the garbage can. The entire structure completes the garbage can operation inside the equipment. The silent rolling door isolates the noise by 10dB, reducing the noise level. 3. Water conservation and recycling: The water consumption for cleaning trash cans is controlled by a program that automatically opens the water valve and controls the time and water flow, effectively conserving water. Cleaning one trash can requires less than 4 liters of water. Simultaneously, the water used for cleaning the trash cans is filtered through a screen, settled, and treated for oil removal, allowing it to be recycled for multiple cleanings. This minimizes water waste. 4. The water consumption for cleaning trash cans is controlled by a program. The water pump is automatically turned on, and the time and water flow are controlled to effectively save water. The water consumption can be controlled within one liter to clean one trash can. At the same time, the water used to clean the trash cans is filtered through the trash filter box drawer, and after sedimentation and oil filtration, the water can be recycled and reused to clean the trash cans multiple times, so as to minimize the waste of water resources. 5. Furthermore, when cleaning the inside of the trash can, the spray range of the rotating pipe can be automatically adjusted. When cleaning the rounded corners inside the trash can, the jet direction is vertical or nearly vertical, aimed at the inner wall of the rounded corner to ensure concentrated water pressure. When cleaning the straight walls inside the trash can, the rotating pipe swings back and forth to expand the spray range, demonstrating a high degree of automation and intelligence. 6. At the same time, when cleaning the inside of the trash can, the water flow direction of the rotating pipe can be adjusted according to the actual situation inside the trash can. When there is less dirt inside the trash can, the spraying range can be expanded, and when there is more dirt inside the trash can, the spraying range can be reduced, making the water flow more concentrated, thereby improving the cleaning effect of the trash can.

[0015] See Figures 1-15 A smart trash can washing robot includes a main frame 1, which is 2.4 meters long, 1.4 meters wide, and 2.2 meters high, occupying only 3.36 square meters of space. A silent, high-speed rolling door 2 is fixedly installed on the front of the main frame 1, and an industrial control computer 3 is also fixedly installed on the front of the main frame 1. The industrial control computer 3 can control the opening and closing of the silent, high-speed rolling door 2. When the trash can needs to be cleaned, the trash can is placed inside the main frame 1, and the silent, high-speed rolling door 2 is activated by the industrial control computer 3, which can simply seal the main frame 1 to prevent cleaning water from splashing everywhere during the trash can cleaning process. A ramp step 7 is fixedly installed on the front side of the main frame 1. The trash can that needs to be cleaned can be pushed into the main frame 1 by using the ramp step 7, which saves time and effort. The main frame 1 is internally fixedly equipped with a flipping assembly, an external brush assembly 8, and a central brush assembly 14. The flipping assembly includes multiple flipping shafts 24 rotatably mounted within the main frame 1. Each flipping shaft 24 is fixedly connected to a flipping sprocket on its outer side. The outer sides of the multiple flipping sprockets are connected to a flipping chain 17 for transmission. A flipping frame 26 is fixedly connected to the outer side of the flipping chain 17. A chain drive motor 10 is fixedly mounted inside the main frame 1. A connecting sprocket is fixedly connected to the outer side of one of the flipping shafts 24 and the output shaft of the chain drive motor 10. A connecting chain is driven to the outer sides of the two connecting sprockets. Multiple buckles are fixedly mounted on the outer side of the flipping frame 26. When cleaning of the trash can is required, it is secured to the tilting frame 26 using clips. The chain drive motor 10 is then activated. The chain drive motor 10, through a connecting sprocket and chain, drives the tilting shaft 24 to rotate. The tilting shaft 24, through the tilting sprocket, drives the tilting chain 17 to move. The tilting chain 17, through the tilting frame 26, moves the trash can. Figure 5 As shown, the trash can moves along the upper part of the flipping chain 17, that is, the trash can first moves upward, then rotates around the flipping shaft 24, and then moves to the right with the flipping frame 26 to perform the corresponding cleaning operation. The external brush assembly 8 includes two side brush assemblies 22, an upper brush assembly 21, and a lower brush assembly 23, as shown below. Figure 5 As shown, two side brush assemblies 22, one upper brush assembly 21, and one lower brush assembly 23 are arranged in a rectangular pattern within the main frame 1. The components of each assembly are identical, including a cleaning shaft and cleaning brushes fixedly mounted on the outside of the cleaning shaft. A bevel gear is fixedly connected to the outside of each cleaning shaft, with adjacent bevel gears meshing. A drive sprocket is fixedly mounted on the outside of one of the cleaning shafts. A brush drive motor 6 is fixedly mounted within the main frame 1. A drive sprocket is also fixedly mounted on the outside of the output shaft of the brush drive motor 6. A drive chain 25 connects the two drive sprockets. When cleaning the trash can, the brush drive motor 6 is activated. The brush drive motor 6 drives the cleaning shaft to rotate via the power sprocket and power chain 25. Under the action of the bevel gear, it drives all other cleaning shafts to rotate. The cleaning shaft drives the cleaning brush to rotate, and the cleaning brush comes into contact with the outer surface of the trash can, thus cleaning the outer surface of the trash can. The central brush assembly 14 includes a central tube 28 rotatably mounted within the main frame 1. A rotating bearing is fixedly mounted on the central tube 28 and its side wall, and the rotating bearing is connected to a water pipe 15. A central plate 32 is fixedly mounted at the end of the central tube 28. Movable plates 35 are slidably mounted on both sides of the central plate 32. An inner wall brush 31 is fixedly mounted on the outer side of the movable plate 35. A four-way pipe 33 is fixedly mounted at the end of the central tube 28. Two output ends of the four-way pipe 33 are fixedly connected to flexible hoses 34, and rotating pipes 52 are fixedly connected to the outer side of the flexible hoses 34. A central brush motor 16 is also fixedly installed inside the main frame 1. A central sprocket is fixedly connected to the output shaft of the central brush motor 16 and the outer side of the central tube 28. A central chain 27 is driven to the outer side of the two transmission sprockets. A cross brush assembly 29 is fixedly connected to the outer side of the central tube 28. The cross brush assembly 29 includes a fixed cylinder fixedly installed on the outer side of the central tube 28, and a cross brush is fixedly installed on the outer side of the fixed cylinder. When cleaning the trash can, the cleaning water in pipe 15 flows into the central pipe 28, and then into the four-way pipe 33, such as... Figure 8 As shown, one output end of the four-way pipe 33 is fixedly inserted through the side wall of the central plate 32, while the other two output ends are fixedly connected to hoses 34. Part of the cleaning water flowing into the four-way pipe 33 flows out from the output end fixedly connected to the side wall of the central plate 32 and sprays onto the bottom of the trash can. The remaining part flows out through the hoses 34 towards the rotating pipe 52 and sprays onto the inner wall of the trash can. During this process, the central brush motor 16 is activated. The central brush motor 16 drives the central pipe 28 to rotate via the central sprocket and central chain 27. The central pipe 28 drives the fixed cylinder and the cross brush to rotate. The cross brush abuts against the inner wall of the trash can, cleaning the inside of the trash can. Simultaneously, the central pipe 28 also drives the central plate 32 to rotate, adjusting the spray range of the rotating pipes 52 on both sides. A control component is fixedly installed inside the central plate 32. The control component can automatically adjust the spray range of the rotating pipe 52 according to the position of the inner wall brush 31 inside the trash can. When cleaning the rounded corners inside the trash can, the jet direction is vertical or nearly vertical, aimed at the inner wall of the rounded corner to ensure concentrated water pressure. When cleaning the straight walls inside the trash can, the rotating pipe 52 swings back and forth to expand the spray range. The water spray assembly includes a disinfection tank 5, a water tank 13, and a water pump 11, all fixedly installed within the main frame 1. The disinfection tank 5, water tank 13, and water pump 11 are connected via multiple water pipes 15, and multiple nozzles are fixedly installed on the outside of the water pipes 15. When cleaning the trash can, the water pump 11 is activated. The water pump 11 causes the disinfectant in the disinfection tank 5 and the cleaning water in the water tank 13 to flow into the water pipe 15, and then be discharged through the nozzle, spraying the inside and outside of the trash can. This, combined with the tilting component, the external brush component 8 and the central brush component 14, completes the cleaning of the trash can. The main frame 1 also includes a slidable garbage filter drawer 18 and a wastewater collection tank 19, with a drain outlet 20 at the bottom. A wastewater recovery pump 12 is fixedly installed inside the main frame 1. When the trash can is cleaned, the wastewater generated falls into the wastewater collection tank 19. Under the action of the wastewater recycling pump 12, the clean water that falls into the wastewater collection tank 19 can be returned to the tank 13, achieving the effect of water recycling. After multiple water recycling, the clean water can be discharged through the drain outlet 20 for replacement. The water consumption for cleaning the trash can is controlled by the program, which automatically turns on the water spray pump 11 and controls the time and water flow to effectively save water. The water consumption can be controlled within 4 liters to clean one trash can. At the same time, the water used to clean the trash can is filtered through the trash filter screen drawer 18, and after sedimentation and oil filtration, this water can be recycled and reused to clean the trash can multiple times, so as to minimize the waste of water resources.

[0016] The control components include a displacement encoder 44, a moving component, and a positioning component. The displacement encoder 44 is fixedly installed on the outside of the center plate 32. The positioning component can determine the rotation point of the rotating tube 52. The moving component can make the rotating tube 52 rotate back and forth around the rotation point. The displacement encoder 44 can control the amplitude of the rotation of the rotating tube 52. The moving component drives the moving plate 35 to move back and forth through the buffer component. The buffer component can drive the positioning component to move, thereby changing the rotation point.

[0017] The moving component includes a first hydraulic cylinder 36 fixedly installed inside the center plate 32, a moving frame 37 sleeved on the outside of the rotating tube 52, connecting plates 51 fixedly connected to both sides of the moving frame 37, a buffer component fixedly connected to the connecting plates 51, and the output end of the first hydraulic cylinder 36 fixedly connected to the buffer component. The positioning component includes a control ring 55 slidably sleeved on the outside of the rotating tube 52, a control frame 53 rotatably connected to the outside of the control ring 55, the control frame 53 slidably connected to the center plate 32, a second hydraulic cylinder 54 fixedly installed inside the center plate 32, and the output ends of the control frame 53 and the second hydraulic cylinder 54 fixedly connected. First, the displacement encoder 44 is a sensor that accurately measures position, displacement, and angle. The displacement encoder 44 is electrically connected to the controller that controls the switching and power of the first hydraulic cylinder 36. When the center plate 32 drives the displacement encoder 44 to rotate, its movement trajectory is arc-shaped. When the center plate 32 is opposite to the inner wall area of ​​the trash can, the distance between the displacement encoder 44 and the inner wall of the trash can changes. At this time, the displacement encoder 44 will emit a large electrical signal, which in turn causes the first hydraulic cylinder 36 to output a large power. That is, the first hydraulic cylinder 36 will drive the buffer assembly to move back and forth, and the amplitude of the back-and-forth movement is large. This is the conventional use of the controller and will not be elaborated further. This, in turn, drives the connecting plate 51 to move back and forth (the structure and principle of this operation are explained below). When the center plate 32 and the rounded corner inside the trash can are aligned, the distance between the displacement encoder 44 and the inner wall of the trash can varies little. At this time, the displacement encoder 44 will emit a small electrical signal, which will cause the first hydraulic cylinder 36 to output a small power. That is, the first hydraulic cylinder 36 will drive the buffer assembly to move back and forth, and the amplitude of the back and forth movement is small. When cleaning the trash can, the first hydraulic cylinder 36 is activated. The first hydraulic cylinder 36 drives the connecting plate 51 to move back and forth through the buffer assembly. During this process, the connecting plate 51 drives the moving frame 37 to move back and forth. The moving frame 37 and the rotating tube 52 abut against each other, thereby driving the rotating tube 52 to move back and forth. When the center plate 32 is opposite to the straight wall area inside the trash can, the connecting plate 51 moves back and forth with a larger amplitude. When the center plate 32 is opposite to the rounded corner inside the trash can, the connecting plate 51 moves back and forth with a smaller amplitude. Ultimately, when cleaning the rounded corner inside the trash can, the jet direction is vertical or nearly vertically aligned with the inner wall of the rounded corner, ensuring concentrated water pressure. When cleaning the straight wall inside the trash can, the rotating tube 52 swings back and forth, expanding the spraying range.

[0018] The buffer assembly includes multiple fixed clamping plates 39 fixedly installed on the upper side of the connecting plate 51. The multiple fixed clamping plates 39 are in pairs, and the position and number of each pair of fixed clamping plates 39 are opposite to the moving plate 35. A fixed rod 40 is fixedly connected between each pair of fixed clamping plates 39. A sleeve 42 is slidably sleeved on the outside of the fixed rod 40. A buffer spring 41 is fixedly connected between the sleeve 42 and the fixed clamping plate 39. A square rod 38 is slidably connected to the sleeve 42. The square rod 38 is fixedly connected to the moving plate 35. A touch switch 43 is fixedly connected to the side wall of the fixed clamping plate 39. First, the touch switch 43 is electrically connected to the controller that controls the second hydraulic cylinder 54. Second, during the reciprocating movement of the connecting plate 51, the connecting plate 51 drives the fixed clamping plate 39 to move back and forth. The fixed clamping plate 39 drives the sleeve 42 to move back and forth via the buffer spring 41. The sleeve 42 drives the moving plate 35 to move back and forth via the square rod 38. The moving plate 35 drives the inner wall brush 31 to move back and forth. The inner wall brush 31 abuts against the inner wall of the trash can, which can better achieve the cleaning effect on the inner wall of the trash can. Meanwhile, if there is a lot of debris inside the trash can, affecting the movement of the inner wall brush 31, it will cause the sleeve 42 to move relative to the fixed clamp 39. The sleeve 42 will then abut against the touch switch 43, thereby activating the second hydraulic cylinder 54. The second hydraulic cylinder 54 will drive the control frame 53 and control ring 55 to move as a whole. Figure 10From this perspective, it will cause the control frame 53 and the control ring 55 to move to the upper left. During this process, the rotating pipe 52 swings around the control ring 55, and the distance between the control ring 55 and the moving frame 37 increases. When the moving frame 37 rotates back and forth, the rotation angle of the rotating pipe 52 will decrease, which will make the water jet from the rotating pipe 52 more concentrated and hit the inner wall of the trash can, thus better cleaning the inner wall of the trash can.

[0019] A manifold assembly is fixedly installed on the outside of the control frame 53. The manifold assembly can increase the pressure of the cleaning water sprayed from the rotating pipe 52, improve the penetration, and improve the cleaning effect on the rounded corners of the trash can. The manifold assembly includes two square plates 49 that are slidably installed at the end of the rotating pipe 52. A limit frame 56 is fixedly connected to the outside of the rotating pipe 52. A limit groove 57 is opened on the side wall of the limit frame 56. A limit rod 58 is slidably connected in the limit groove 57. A limit plate 59 is rotatably connected to the outside of the limit rod 58. The limit plate 59 is rotatably connected to the control ring 55. A movable clamp 50 is fixedly connected to the outside of the limit rod 58. The movable clamp 50 is fixedly connected to the square plate 49. In the initial state, the obstruction of the square plate 49 creates a diversion effect on the water flow sprayed from the rotating pipe 52, further expanding the spraying range of the rotating pipe 52. Furthermore, due to the angle between the diversion plate 48 and the square plate 49 near the rotating pipe 52, a portion of the water flow is directly sprayed onto the inner wall brush 31 under the guidance of the diversion plate 48, cleaning the inner wall brush 31 and ensuring it remains in good working condition. When the control ring 55 and control frame 53 move, the limit plate 59 causes the limit rod 58 and the moving clamp 50 to move away from each other, losing the diversion effect on the water flow sprayed from the rotating pipe 52. This causes the water flow from the rotating pipe 52 to be sprayed more concentratedly onto the inner wall of the trash can, improving the cleaning effect.

[0020] A groove is opened on one side of the square plate 49, and a diversion plate 48 is rotatably connected in the groove. A compression spring 47 is fixedly connected between the diversion plate 48 and the square plate 49. A round rod 46 is fixedly connected to the outside of the diversion plate 48. Multiple protrusions 45 are evenly fixedly connected to the side wall of the limiting frame 56. During the movement of the square plate 49, the action of the round rod 46 and the protrusion 45 will cause the diversion plate 48 to shake to a certain extent, which will cause the cleaning water sprayed along the diversion plate 48 to further clean the inner wall brush 31, so that the inner wall brush 31 can maintain a good working condition.

[0021] In this invention, when it is necessary to clean the trash can, the trash can is fixed on the flip frame 26 by the buckle, the chain drive motor 10 is started, the chain drive motor 10 drives the flip shaft 24 to rotate through the connecting sprocket and the connecting chain, the flip shaft 24 drives the flip chain 17 to move through the flip sprocket, and the flip chain 17 drives the trash can to move through the flip frame 26, so that the trash can first moves upward, then rotates around the flip shaft 24 as the center, and then moves to the right with the flip frame 26 to perform the corresponding cleaning operation; Start the brush drive motor 6. The brush drive motor 6 drives the cleaning shaft to rotate through the power sprocket and power chain 25. Under the action of the bevel gear, it drives all other cleaning shafts to rotate. The cleaning shaft drives the cleaning brush to rotate. The cleaning brush and the outer surface of the trash can come into contact with each other to clean the outer surface of the trash can. When cleaning the trash can, the cleaning water in the water pipe 15 flows into the central pipe 28 and then into the four-way pipe 33. Part of the cleaning water flowing into the four-way pipe 33 flows out from the output end that is fixedly connected to the side wall of the central plate 32 and sprays onto the bottom of the trash can. The rest flows out through the hose 34 and the rotating pipe 52 and sprays onto the inner wall of the trash can. At the same time, the central brush motor 16 is started. The central brush motor 16 drives the central pipe 28 to rotate through the central sprocket and the central chain 27. The central pipe 28 drives the fixed cylinder and the cross brush to rotate. The cross brush abuts against the inner wall of the trash can, forming a cleaning of the inside of the trash can. At the same time, the central pipe 28 also drives the central plate 32 to rotate, adjusting the spraying range of the rotating pipes 52 on both sides. When the trash can is being cleaned, the wastewater generated falls into the wastewater collection tank 19. Under the action of the wastewater recycling pump 12, the clean water that falls into the wastewater collection tank 19 can be returned to the tank 13, achieving the effect of water recycling. After multiple water recycling, the clean water can be discharged through the drain outlet 20 for replacement. The water consumption for cleaning the trash can is controlled by the program, which automatically turns on the water spray pump 11 and controls the time and water flow to effectively save water. The water consumption can be controlled within 4 liters to clean one trash can. At the same time, the water used to clean the trash can is filtered through the trash filter box drawer 18, and after sedimentation and oil filtration, this water can be recycled and reused to clean the trash can multiple times, so as to minimize the waste of water. When the center plate 32 and the rounded corner inside the trash can are facing each other, the distance between the displacement encoder 44 and the inner wall of the trash can changes within a small range. At this time, the displacement encoder 44 will emit a small electrical signal, which will cause the first hydraulic cylinder 36 to output a small power. That is, the first hydraulic cylinder 36 will drive the buffer assembly to move back and forth, and the amplitude of the back and forth movement is small. When cleaning the trash can, the first hydraulic cylinder 36 is activated. The first hydraulic cylinder 36 drives the connecting plate 51 to move back and forth through the buffer assembly. During this process, the connecting plate 51 drives the moving frame 37 and the rotating tube 52 to move back and forth. When the center plate 32 and the straight wall area inside the trash can are facing each other, the amplitude of the back and forth movement of the connecting plate 51 is large. When the center plate 32 and the rounded corner inside the trash can are facing each other, the amplitude of the back and forth movement of the connecting plate 51 is small. As the connecting plate 51 moves back and forth, it drives the fixed clamping plate 39, buffer spring 41, sleeve 42, square rod 38, moving plate 35, and inner wall brush 31 to move back and forth. The inner wall brush 31 abuts against the inner wall of the trash can, which can better achieve the cleaning effect on the inner wall of the trash can. Meanwhile, if there is a lot of debris inside the trash can, which affects the movement of the inner wall brush 31, the sleeve 42 will move relative to the fixed clamp 39. The sleeve 42 will abut against the touch switch 43, which will then activate the second hydraulic cylinder 54. The second hydraulic cylinder 54 will drive the control frame 53 and the control ring 55 to move as a whole. The rotating tube 52 will swing around the control ring 55 as the center. The distance between the control ring 55 and the moving frame 37 will increase. When the moving frame 37 rotates back and forth, the rotation angle of the rotating tube 52 will decrease, which will make the water jet from the rotating tube 52 more concentrated and spray towards the inner wall of the trash can, thus better cleaning the inner wall of the trash can. The obstruction of the square plate 49 creates a diversion effect on the water flow sprayed from the rotating pipe 52, further expanding the spraying range of the rotating pipe 52. Furthermore, due to the angle between the diversion plate 48 and the square plate 49 near the rotating pipe 52, a portion of the water flow is directly sprayed onto the inner wall brush 31 under the guidance of the diversion plate 48, cleaning the inner wall brush 31 and ensuring it remains in good working condition. When the control ring 55 and control frame 53 move, the limit plate 59 causes the limit rod 58 and the moving clamp 50 to move away from each other, losing the diversion effect on the water flow sprayed from the rotating pipe 52. This causes the water flow sprayed from the rotating pipe 52 to be more concentrated and sprayed onto the inner wall of the trash can, improving the cleaning effect. During the movement of the square plate 49, the action of the round rod 46 and the protrusion 45 will cause the diversion plate 48 to shake to a certain extent, which will cause the cleaning water sprayed along the diversion plate 48 to further clean the inner wall brush 31, so that the inner wall brush 31 can maintain a good working condition.
