Description

Technical Field

[0001] This application relates to the field of cleaning devices, and more specifically to a 360-degree rotating nozzle cleaning device. Background Technology

[0002] Trash cans are common items in daily life. When using trash cans, dust and other debris usually stick to the inner or outer walls, requiring users to manually clean them. This is especially true for kitchen waste bins, which need to be cleaned more frequently, increasing the workload for users. Summary of the Invention

[0003] The main purpose of this application is to reduce the workload of users.

[0004] To achieve the above objectives, this application provides a 360-degree rotating nozzle cleaning device, which adopts the following technical solution:

[0005] A 360-degree rotating nozzle cleaning device includes a rectangular shell-shaped frame. The upper part of one side wall of the frame is inclined outward. A four-channel rotary joint is installed on the inclined side wall of the frame. The rotary joint includes a stator and a rotor. The stator is located outside the frame, and the channel outlet end of the rotor is located inside the frame. The channel outlet end of the rotor is provided with a cleaning mechanism, which includes an inner wall cleaning component and an outer wall cleaning component.

[0006] The inner wall cleaning component includes an inner wall foam sprayer, an inner wall water sprayer, and an inner wall air sprayer, and the three are centrally distributed. The outer wall cleaning component includes an outer wall foam sprayer, an outer wall water sprayer, and an outer wall air sprayer, and the three are distributed around the inner wall cleaning component in a circumferential manner.

[0007] The outer wall of the frame is also provided with a drive assembly for driving the rotary joint rotor to rotate, and a control assembly for controlling the operation of the drive assembly and the cleaning mechanism.

[0008] By adopting the above technical solution, when the trash can needs to be cleaned, the operator uses the clamping device to insert the trash can into the frame, with the inner wall cleaning component inside the trash can and the outer wall cleaning component outside. The operator then activates the control component, which controls the drive component to operate, causing the rotor to drive the inner and outer wall cleaning components to rotate. Simultaneously, the control component controls the inner and outer wall foam spraying components to operate, spraying foam onto the inner and outer walls of the trash can. Next, the control component controls the inner and outer wall water spraying components to operate, rinsing the foam off the inner and outer walls of the trash can. Then, the control component controls the inner and outer wall air spraying components to operate, blowing off the water from the inner and outer walls of the trash can. Finally, the control component stops the drive component, and the operator removes the trash can from the frame. Through this operation, the purpose of automatically cleaning the trash can is achieved, reducing the need for users to manually clean the trash can and lowering their workload.

[0009] Optionally, the four passages of the stator are each connected to a cleaning liquid inlet pipe, a water inlet pipe, a first air inlet pipe, and a second air inlet pipe. The cleaning liquid inlet pipe is connected to a cleaning liquid source, the water inlet pipe is connected to a water source, and the first air inlet pipe and the second air inlet pipe are both connected to an air source. The four passages of the rotor are also connected to a cleaning liquid outlet pipe, a water outlet pipe, a first air outlet pipe, and a second air outlet pipe.

[0010] The inner wall foam spraying component includes an inner foam tube equipped with a nozzle and an inner jet injector, a first inner air outlet branch pipe connected to both the first air outlet pipe and the inner jet injector, and an inner cleaning liquid outlet branch pipe connected to both the cleaning liquid outlet pipe and the inner jet injector.

[0011] The inner wall spray component includes an inner water outlet branch pipe connected to the water outlet pipe, and a nozzle is installed on the inner water outlet branch pipe;

[0012] The inner wall jetting component includes a second inner air outlet branch pipe connected to the second air outlet pipe, and a number of nozzles are installed on the second inner air outlet branch pipe.

[0013] The outer wall foam spraying component includes an outer foam tube equipped with a nozzle and an outer jet injector, a first outer air branch pipe connected to both the first air outlet pipe and the outer jet injector, and an outer cleaning liquid branch pipe connected to both the cleaning liquid outlet pipe and the outer jet injector.

[0014] The external wall spray system includes an outgoing water branch pipe connected to the outgoing water pipe, and a nozzle is installed on the outgoing water branch pipe;

[0015] The outer wall jet component includes a second outer air branch pipe connected to the second air outlet pipe, and several nozzles are installed on the second outer air branch pipe.

[0016] By adopting the above technical solution, when the inner wall foam spraying component and the outer wall foam spraying component are working, the control component controls the cleaning liquid source and the air source to work. The cleaning liquid source delivers the cleaning liquid to the inner outlet cleaning liquid branch pipe and the outer outlet cleaning liquid branch pipe through the inlet cleaning liquid pipe and the outlet cleaning liquid pipe. The air source delivers the gas to the first inner outlet air branch pipe and the first outer outlet air branch pipe through the first inlet air pipe and the first outer outlet air branch pipe. The inner jet device works to mix the cleaning liquid in the inner outlet cleaning liquid branch pipe and the gas in the first inner outlet air branch pipe to form foam, which is then delivered to the foam pipe and sprayed out from the nozzle on the inner foam pipe. The outer jet device works to mix the cleaning liquid in the outer outlet cleaning liquid branch pipe and the gas in the first outer outlet air branch pipe to form foam, which is then delivered to the outer foam pipe and sprayed out from the nozzle on the outer foam pipe.

[0017] When the inner and outer wall water spray components are working, the control component controls the water source to work. The water source delivers water through the inlet and outlet pipes to the inner outlet branch pipe and the outer outlet branch pipe. The nozzles on the inner outlet branch pipe and the outer outlet branch pipe spray water onto the trash can.

[0018] When the inner and outer wall air jets are working, the control component controls the air source to work. The air source delivers gas through the second inlet pipe and the second outlet pipe to the second inner outlet branch pipe and the second outer outlet branch pipe. The nozzle on the second inner outlet branch pipe sprays gas onto the inner wall of the trash can, and the nozzle on the second outer outlet branch pipe sprays gas onto the outer wall of the trash can.

[0019] Optionally, the drive assembly includes a drive motor and a reducer mounted on the frame. The output shaft of the drive motor is coaxial with and fixedly connected to the input shaft of the reducer. A coaxial drive wheel is fixedly connected to the output shaft of the reducer. A coaxial driven wheel is fixedly connected to one end of the rotor outside the frame. A synchronous belt is fitted together on the drive wheel and the driven wheel.

[0020] By adopting the above technical solution, the operation of the motor causes the output shaft of the reducer to drive the drive wheel to rotate, and the drive wheel drives the driven wheel and the rotor to rotate through the synchronous belt.

[0021] Optionally, the control component includes a connecting ring fixed on the end face of the driven wheel away from the frame. The connecting ring is coaxial with the driven wheel. Two opposing sensing plates are fixedly connected to the side wall of the driven wheel. Two sensors adapted to the sensing plates are installed on the frame. The line connecting the two sensors and the driven wheel rotation shaft is a straight line. The control component also includes a controller, which is electrically connected to the drive motor, sensors, cleaning liquid source, water source, and air source.

[0022] By adopting the above technical solution, the controller controls the drive motor to work, thereby causing the rotor to drive the cleaning mechanism to rotate. During this process, the controller controls the cleaning liquid source and air source to work, causing the cleaning mechanism to spray foam onto the trash can. Then, the controller controls the water source to work, causing the cleaning mechanism to rinse the foam off the trash can. Then, the controller controls the air source to work, causing the cleaning mechanism to blow the water off the trash can. After the controller controls the cleaning mechanism to complete the above cleaning steps, as the motor continues to work, the rotor drives the connecting ring and the sensing plate to rotate. When one of the sensing plates engages with one of the sensors, the sensor transmits a signal to the controller, and the controller controls the motor to stop working. At this time, the operator can remove the trash can from the frame.

[0023] Optionally, a horizontal plate is provided in the middle of the frame, and the circumferential side walls of the frame are all fixed to the side walls corresponding to the horizontal plate. A partition is provided between the horizontal plate and the inner bottom wall of the frame. The partition is fixed to the horizontal plate and the inner bottom wall of the frame. The partition divides the space below the horizontal plate into a first chamber and a second chamber. A water inlet hole communicating with the first chamber is also provided on the horizontal plate, and a connecting hole communicating with the first chamber and the second chamber is provided on the partition.

[0024] The first chamber is equipped with a sieve plate for the first filtration of water, and the second chamber is equipped with a filter plate for the second filtration of water. The filter plates are located below the connecting holes.

[0025] The frame is connected to a return water pipe that communicates with the second chamber. The inlet end of the return water pipe is located below the filter plate. The return water pipe is connected to the cleaning liquid source and a pump is installed on the return water pipe.

[0026] By adopting the above technical solution, the water generated during the cleaning of the trash can flows into the first chamber through the inlet hole. The sieve plate performs the first filtration of the water flowing into the first chamber. The filtered water flows into the second chamber through the connecting hole and then falls onto the filter plate, which performs the second filtration. The water that has undergone the second filtration falls to the bottom of the frame for settling, thereby allowing the impurities in the water to settle at the bottom of the frame. When it is necessary to prepare the cleaning solution, the operator starts the pump on the return water pipe. The pump on the return water pipe pumps the settled water into the cleaning solution source through the return water pipe, achieving the purpose of wastewater reuse, saving resources and reducing cleaning costs.

[0027] Optionally, the first chamber is further provided with a sealing component for controlling the opening and closing of the communication hole.

[0028] By adopting the above technical solution, when the connecting hole is open, water in the first chamber continuously flows into the second chamber, which will cause continuous water flow in the second chamber and have an adverse effect on water settling. The sealing component controls the opening and closing of the connecting hole, so that water can enter the second chamber intermittently. When the second chamber stops entering water, the water at the bottom of the second chamber can settle better.

[0029] Optionally, the sealing assembly includes sealing blocks fixedly connected to the screen plate, with each sealing block corresponding to a connecting hole. The screen plate is slidably connected to the lower surface of the frame. The first chamber is provided with a lead screw and a guide rod. The two ends of the lead screw are rotatably connected to the partition plate and the corresponding side wall of the frame, respectively. The two ends of the guide rod are fixed to the partition plate and the corresponding side wall of the frame, respectively. The lead screw passes through the screen plate and is threaded into the screen plate. The guide rod passes through the screen plate and is inserted into the screen plate. A sealing motor for driving the lead screw to rotate is installed on the frame.

[0030] By adopting the above technical solution, when the connecting hole is closed, the sealing motor and the lead screw work together to make the screen plate and the partition plate fit together. At this time, the sealing block is inserted into the connecting hole, and the sealing block can block the connecting hole and prevent water in the first chamber from flowing into the second chamber. When it is necessary to open the connecting hole, the operator controls the sealing motor to work. The sealing motor drives the lead screw to rotate. At the same time, the lead screw and the guide rod work together to move the screen plate away from the partition plate. The screen plate drives the sealing block to move, so that the sealing block is disengaged from the connecting hole. At this time, the connecting hole is opened, and the water in the first chamber flows into the second chamber through the connecting hole.

[0031] Optionally, the sieve plate includes an upper plate and a lower plate, the upper plate and the lower plate are hinged together, the lower plate is slidably connected to the lower surface of the frame, the lead screw and the guide rod are both engaged with the lower plate, a connecting block is hinged to the side wall of the upper plate near the partition, the connecting block is slidably connected to the partition, a spring is fixedly connected to the connecting block, the spring is fixedly connected to the partition, and the sliding direction of the connecting block and the extension direction of the spring are both set along the height direction of the frame.

[0032] By adopting the above technical solution, when the blocking block is engaged with the connecting hole, the spring supports the connecting block, making the upper plate vertical. Used water flows into the first chamber through the water inlet, and the upper and lower plates cooperate to filter the water. When the blocking motor, lead screw, and guide rod work together to move the lower plate away from the partition, the lower plate moves the lower side of the upper plate, and at the same time, the upper side of the upper plate moves the connecting block downward. As the connecting block moves, the spring is further compressed, and the lower side of the upper plate rotates and tilts away from the partition. At this time, the upper and lower plates cooperate to filter the water better, reducing the situation where unfiltered water flows directly between the screen plate and the partition, thereby reducing the possibility of unfiltered water flowing into the second chamber.

[0033] Optionally, a connecting rod is fixedly connected to the side wall of the sieve plate of the sealing block, and a cleaning plate is hinged to the upper surface of the filter plate near the partition. The cleaning plate has multiple through holes with a diameter smaller than the sieve hole diameter of the sieve plate. A hinge rod that is hinged to the connecting rod and is hinged to the cleaning plate is also connected. When the sealing block is engaged with the through hole, the cleaning plate covers the filter plate.

[0034] By adopting the above technical solution, when water flows into the second chamber, it first passes through the cleaning plate for filtration, and then flows onto the filter plate for further filtration. Most of the debris in the second chamber remains on the cleaning plate, reducing the occurrence of debris clogging the filter plate and thus reducing the frequency of filter plate replacement. When the sealing block blocks the connecting hole, the cleaning plate becomes horizontal under its own weight and covers the filter plate. When the filter plate and the sealing block move away from the partition, the sealing block drives the connecting rod and the hinge rod to move, while the hinge rod pulls the cleaning plate to rotate, causing the side of the cleaning plate away from the partition to move upward. When the connecting hole opens, the water flows and washes against the inclined cleaning plate, thereby flushing the debris on the cleaning plate to the position between the cleaning plate and the partition for collection, reducing the occurrence of debris clogging the cleaning plate and also reducing the frequency of cleaning the cleaning plate by the operator.

[0035] In summary, this application includes at least one of the following beneficial technical effects:

[0036] 1. By setting up a frame, rotary joint, inner wall foam spraying components, inner wall water spraying components, inner wall air spraying components, outer wall foam spraying components, outer wall water spraying components, outer wall air spraying components, drive components, and control components, the purpose of automatically cleaning the trash can is achieved, reducing the need for users to manually clean the trash can and reducing the workload of users;

[0037] 2. By setting up a horizontal plate, water inlet hole, partition plate, connecting hole, sieve plate and filter plate, return water pipe and pump body, the pump body on the return water pipe pumps the settled water into the cleaning liquid source through the return water pipe, so as to achieve the purpose of wastewater reuse, save resources and reduce cleaning costs.

[0038] 3. By setting up a cleaning plate, connecting rod, and hinge rod, the frequency of filter plate replacement is reduced, the occurrence of debris clogging the cleaning plate is reduced, and the frequency of cleaning the cleaning plate by operators is also reduced. Attached Figure Description

The controller 85 is electrically connected to the drive motor 71, the sensors 81, the pump bodies of the cleaning liquid tank 3 and the clean water tank 4, the air pump 5, and the valve of the air pump 5.

[0065] When cleaning the trash can, the operator uses a clamp to insert the trash can into the frame 1 and covers the trash can outside the inner wall cleaning component 61, while the outer wall cleaning component 62 is located outside the trash can; at this time, the operator starts the controller 85, the controller 85 controls the drive motor 71 to work, so that the rotor 22 drives the inner wall cleaning component 61 and the outer wall cleaning component 62 to rotate.

[0066] Simultaneously, the controller 85 also controls the operation of the pump body of the cleaning liquid tank 3, the air pump 5, and the valve body corresponding to the air pump 5, so that the air pump 5 pumps gas into the first air inlet pipe 213. After passing through the first air inlet pipe 213 and the first air outlet pipe 223, the gas simultaneously enters the first inner air outlet branch pipe 6111 and the first outer air outlet branch pipe 6214. The pump body on the cleaning liquid tank 3 pumps the cleaning liquid into the cleaning liquid inlet pipe 211. After passing through the cleaning liquid outlet pipe 221, the cleaning liquid simultaneously flows into the inner air outlet branch pipe 6112 and the outer air outlet branch pipe 6211. The inner ejector 6114 and the outer ejector 6213 work to mix the cleaning liquid and gas to form foam. The foam formed by the inner ejector 6114 enters the inner foam pipe 6113, and the foam formed by the outer ejector 6213 enters the outer foam pipe 6212.

[0067] The nozzles on the inner foam tube 6113 spray foam onto the inner wall of the trash can, and the nozzles on the outer foam tube 6212 spray foam onto the outer wall of the trash can. Since the rotor 22 drives the inner foam tube 6113 and the outer foam tube 6212 to rotate, the inner foam tube 6113 and the outer foam tube 6212 work together to evenly cover the wall of the trash can with foam. After the controller 85 controls the drive motor 71 to work for a period of time, the entire wall of the trash can is covered with foam, and the controller 85 controls the pump body of the cleaning liquid tank 3 and the air pump 5 to stop working.

[0068] Then, the controller 85 controls the pump body of the water tank 4 to work. The pump body of the water tank 4 pumps water into the inlet pipe 212. After passing through the inlet pipe 212 and the outlet pipe 222, the water flows into the inner outlet branch pipe 6121 and the outer outlet branch pipe 6221. The nozzle on the inner outlet branch pipe 6121 sprays water onto the inner wall of the trash can, thereby rinsing the foam on the inner wall of the trash can. The nozzle on the outer outlet branch pipe 222 sprays water onto the outer wall of the trash can, thereby cleaning the foam on the outer wall of the trash can. Since the rotor 22 drives the inner outlet branch pipe 6121 and the outer outlet branch pipe 6221 to rotate, the foam on the trash can can be rinsed clean.

[0069] After the controller 85 controls the drive motor 71 to work for a period of time, the foam on the walls of the trash can is cleaned. At this time, the controller 85 controls the pump on the clean water tank 4 to stop working. Then, the controller 85 controls the air pump 5 and the corresponding valve to work, so that the air pump 5 pumps gas into the second air inlet pipe 214. Then the gas enters the second inner air outlet branch pipe 6131 and the second outer air outlet branch pipe 6231 through the second air outlet pipe 224. The nozzle on the second inner air outlet branch pipe 6131 sprays the gas onto the inner wall of the trash can, thereby blowing away the water on the inner wall of the trash can. The nozzle on the second outer air outlet branch pipe 6231 sprays the gas onto the outer wall of the trash can, thereby blowing away the water on the outer wall of the trash can.

[0070] Because the rotor 22 drives the second inner air outlet branch pipe 6131 and the second outer air outlet branch pipe 6231 to rotate, the water on the trash can can be sprayed off, thus completing the cleaning of the trash can. As the drive motor 71 continues to work, the driven wheel 74, connecting ring 83, sensing plate 84 and rotor 22 continue to rotate. When one of the sensing plates 84 reaches one of the sensors 81, the outer wall foam spraying component 621, outer wall water spraying component 622 and outer wall air spraying component 623 and the trash can are arranged horizontally. At this time, the sensor 81 transmits a signal to the controller 85, and the controller 85 controls the drive motor 71 to stop working. Finally, the operator removes the trash can from the frame 1. This achieves the purpose of automatically cleaning the trash can and reduces the workload of the user.

[0071] To achieve water resource reuse and reduce cleaning costs, the 360-degree rotating nozzle cleaning device also has the function of recycling and reusing used water; see reference Figure 2 and Figure 6 The frame 1 is provided with a horizontally arranged cross plate 11, which is located below the rotary joint 2. Each circumferential inner wall of the frame 1 is fixedly connected to the side wall corresponding to the cross plate 11.

[0072] Reference Figure 6 and Figure 7 Below the horizontal plate 11, there is a vertically arranged partition 12. The horizontal plate 11, the partition 12, and the inner wall of the frame 1 are fixed. The partition 12 divides the space of the frame 1 below the horizontal plate 11 to form a first chamber 13 and a second chamber 14. A water inlet hole 111 is provided on the horizontal plate 11, which connects the first chamber 13 and the space above the partition 12. The partition 12 is also provided with a number of connecting holes 121 that connect the first chamber 13 and the second chamber 14. In this embodiment, there are two connecting holes 121.

[0073] Reference Figure 6 and Figure 7 The first chamber 13 contains a vertically arranged sieve plate 15 for the first filtration of water. The second chamber 14 contains a horizontally arranged filter plate 16 for the second filtration of water, located below the connecting hole 121. A trough 17 is fixedly connected to the side wall of the partition 12 near the filter plate 16, and a trough 17 is also fixedly connected to the inner wall of the frame 1 opposite to the partition 12. The two troughs 17 are arranged opposite each other, with their openings close to each other. The filter plate 16 is inserted into the two troughs 17. (Refer to...) Figure 1 A return water pipe 18 is fixedly connected to one of the side walls of the frame 1. The connection position between the return water pipe 18 and the frame 1 is lower than that of the filter plate 16. A pump body is also installed on the return water pipe 18. The outlet end of the return water pipe 18 is connected to the cleaning liquid tank 3.

[0074] Water from cleaning the trash can falls from the inlet 111 into the first chamber 13. At the same time, the sieve plate 15 filters the impurities in the water. The water that has passed through the first filtration enters the second chamber 14 through the connecting hole 121 and falls onto the filter plate 16. The filter plate 16 performs a second filtration on the water. The water that has passed through the second filtration naturally falls to the bottom of the second chamber 14 to settle, allowing the impurities in the water to settle. When cleaning solution is needed, the operator starts the pump on the return water pipe 18 to pump the settled water in the second chamber 14 into the cleaning solution tank 3 for reuse, thus saving water resources.

[0075] Reference Figure 6 To facilitate better water settling at the bottom of the second chamber 14, the frame 1 is also equipped with a sealing assembly 9 for controlling the opening and closing of the connecting hole 121. By controlling the opening and closing of the connecting hole 121, water can be intermittently introduced into the second chamber 14, thereby reducing the adverse effects of continuous water flow on water settling. The sieve plate 15 includes an upper plate 151 and a lower plate 152 located below the upper plate 151. The upper plate 151 and the lower plate 152 are hinged together, and the lower plate 152 is slidably connected to the inner bottom wall of the frame 1. The sliding direction of the lower plate 152 is arranged along the arrangement direction of the first chamber 13 and the second chamber 14.

[0076] Reference Figure 6 and Figure 8 A connecting block 1511 is hinged to the side wall of the upper plate 151 near the partition 12. In this embodiment, there is one connecting block 1511. In other embodiments, the number of connecting blocks 1511 can be greater than one. A connecting groove 122 corresponding to the connecting block 1511 is opened on the side wall of the partition 12 near the upper plate 151. The length direction of the connecting groove 122 is set along the height direction of the frame 1. The connecting block 1511 is slidably inserted into the connecting groove 122. The connecting block 1511 and the connecting groove 122 cooperate to make the upper plate 151 and the partition 12 slide together. A spring 1512 is fixedly connected to the lower surface of the connecting block 1511. The extension direction of the spring 1512 is set along the height direction of the frame 1. The lower end of the spring 1512 is fixed to the lower end groove wall of the connecting groove 122. The spring 1512 is always in a compressed state.

[0077] Reference Figure 6 and Figure 7 The lower surface of the lower plate 152 is fixedly connected with a T-shaped slider 1521. In this embodiment, there are two sliders 1521. The inner bottom wall of the frame 1 is provided with a sliding groove 19 corresponding to the slider 1521. The length direction of the sliding groove 19 is consistent with the sliding direction of the lower plate 152. Each slider 1521 is slidably inserted into the corresponding sliding groove 19. The side wall of the sieve plate 15 near the partition plate 12 is fixedly connected with a blocking block 91 corresponding to the connecting hole 121. The blocking block 91 cooperates with the connecting hole 121 to block the connecting hole 121.

[0078] Reference Figure 6 The sealing assembly 9 also includes a lead screw 93 and a guide rod 94 disposed in the first chamber 13. The length direction of both the lead screw 93 and the guide rod 94 is consistent with the sliding direction of the sieve plate 15. The two ends of the lead screw 93 are rotatably connected to the inner walls of the partition plate 12 and the frame 1, respectively. The two ends of the guide rod 94 are fixedly connected to the inner walls of the partition plate 12 and the frame 1, respectively. The lead screw 93 passes through the lower plate 152 and is threadedly connected to the lower plate 152. The guide rod 94 passes through the lower plate 152 and is slidably inserted into the lower plate 152. A sealing motor 92 is installed on the outer wall of the frame 1. The output shaft of the sealing motor 92 is coaxial with the lead screw 93, and the output shaft of the sealing motor 92 is fixed to the end face of the lead screw 93.

[0079] In the initial state, both the upper plate 151 and the lower plate 152 are in contact with the partition 12. At this time, the spring 1512 keeps the connecting block 1511 at the top of the connecting groove 122, and the sealing block 91 is inserted into the corresponding connecting hole 121, thereby sealing the connecting hole 121. The water in the first chamber 13 cannot flow to the second chamber 14, allowing the water in the second chamber 14 to settle better. At this time, the operator can extract the water in the second chamber 14 for use.

[0080] When it is necessary to open the connecting hole 121, the operator controls the sealing motor 92 to work. The sealing motor 92 drives the lead screw 93 to rotate. At the same time, the lead screw 93 and the guide rod 94 cooperate to drive the lower plate 152, the sealing block 91 and the lower side of the upper plate 151 to move away from the partition 12. When the sealing block 91 is disengaged from the connecting hole 121, the water in the first chamber 13 can flow into the second chamber 14 through the connecting hole 121, thereby replenishing the second chamber 14 with water.

[0081] As the lower plate 152 and the lower side of the upper plate 151 move away from the partition 12, the upper plate 151 gradually rotates and tilts. At the same time, the upper side of the upper plate 151 and the connecting block 1511 move downward. The movement of the connecting block 1511 further compresses the spring 1512. During this process, the upper plate 151 is always in contact with the partition 12, so that the upper plate 151 can better filter the water falling into the first chamber 13, reducing the occurrence of unfiltered water falling directly between the screen plate 15 and the partition 12, thereby reducing the possibility of unfiltered water flowing directly into the second chamber 14.

[0082] Reference Figure 6 and Figure 7Since the filter plate 16 is placed horizontally, it is easy for debris to accumulate on the filter plate 16 and block the filter plate 16. At this time, it is necessary to replace the filter plate 16. In order to reduce the replacement frequency of the filter plate 16, the second chamber 14 is also provided with a cleaning component 10 for cleaning debris on the filter plate 16. The cleaning component 10 includes a cleaning plate 101 covering the filter plate 16. One side of the cleaning plate 101 is hinged to the upper surface of the groove 17 near the partition plate 12, and the other side of the cleaning plate 101 overlaps the upper surface of another groove 17 under its own weight. The cleaning plate 101 has multiple through holes, and the diameter of the through holes is smaller than the sieve hole diameter of the sieve plate 15.

[0083] The cleaning assembly 10 also includes connecting rods 102 that correspond one-to-one with the blocking blocks 91. One end of the connecting rod 102 is fixedly connected to the side wall of the blocking block 91 away from the screen plate 15. The end of the connecting rod 102 away from the blocking block 91 is flush with the side wall of the cleaning plate 101 away from the blocking block 91. A hinge rod 103 is hinged to the end of the connecting rod 102 away from the blocking block 91. The lower end of the hinge rod 103 is hinged to the cleaning plate 101. When the blocking block 91 cooperates with the connecting hole 121 to block the connecting hole 121, the cleaning plate 101 is horizontal under its own weight.

[0084] When the sieve plate 15 and the blocking block 91 move away from the partition plate 12, the blocking block 91 drives the upper end of the connecting rod 102 and the hinge rod 103 to move. The movement of the upper end of the hinge rod 103 causes the hinge rod 103 to rotate. The rotation of the hinge rod 103 pulls the cleaning plate 101 to rotate, causing the side of the cleaning plate 101 away from the partition plate 12 to rotate upward, thus making the cleaning plate 101 tilted. Water falls onto the cleaning plate 101 through the connecting hole 121 and then onto the filter plate 16. The cleaning plate 101 filters the impurities in the water. The water that falls onto the cleaning plate 101 afterward can also flush the impurities on the cleaning plate 101, flushing the impurities to the lower side of the cleaning plate 101 for collection. This reduces the accumulation of impurities in the filter plate 16 and the middle of the cleaning plate 101, thereby reducing the frequency of replacing the filter plate 16.

[0085] When the sieve plate 15 and the blocking block 91 move towards the partition plate 12, the blocking block 91 drives the connecting rod 102 and the hinge rod 103 to move back to their initial positions. At the same time, the side of the cleaning plate 101 away from the partition plate 12 rotates downward and resets under its own weight. When the blocking block 91 engages with the connecting hole 121 again, the connecting rod 102, the hinge rod 103, and the cleaning plate 101 all return to their initial positions. To facilitate the cleaning of debris by operators, the frame 1 is provided with handholes that communicate with the first chamber 13 and the second chamber 14.

[0086] The implementation principle of the 360-degree rotating nozzle cleaning device in this application embodiment is as follows: When cleaning the trash can, the operator uses a clamp to insert the trash can into the frame 1, with the trash can covered outside the inner wall cleaning component 61, and the outer wall cleaning component 62 located outside the trash can; the operator controls the drive motor 71, the pump body of the cleaning liquid tank 3, the pump body of the clean water tank 4, the air pump 5, and the valve body corresponding to the air pump 5 through the controller 85, thereby making the inner wall cleaning component 61 and the outer wall cleaning component 62 work, cleaning the inner and outer walls of the trash can in the order of spraying foam, spraying water, and spraying air; after the controller 85 controls the drive motor 71 to work for a certain period of time, when one of the sensing plates 84 passes one of the sensors 81, the controller 85 controls the drive motor 71 to stop working, at which time the operator can remove the trash can from the frame 1.

[0087] Wastewater from cleaning the trash cans falls into the first chamber 13 through the inlet 111. After being filtered by the upper plate 151 and the lower plate 152, the water enters the second chamber 14 through the connecting hole 121. The water entering the second chamber 14 passes through the cleaning plate 101 and the filter plate 16 in sequence, and finally falls to the bottom of the second chamber 14 to settle. When the water in the second chamber 14 reaches a certain amount, the operator controls the sealing motor 92 to work, causing the lower plate 152, the upper plate 151, the sealing block 91, the connecting rod 102, and the cleaning plate 101 to move. When the sealing block 91 blocks the connecting hole 121, the upper plate 151 and the lower plate 152 are in contact with the partition 12, and the cleaning plate 101 is horizontal. After the water in the second chamber 14 has settled for a period of time, the operator controls the pump of the return water pipe 18 to work, and pumps the settled water into the cleaning liquid tank 3.

[0088] Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
