Intelligent garbage house with gate-controlled spraying type disinfection linkage mechanism

Abstract

This invention relates to the field of waste disposal, specifically to an intelligent waste room with a gate-controlled spray disinfection linkage mechanism. The waste room includes a main body with multiple disposal windows on one side. Multiple waste bins are placed inside the main body, located to one side of the disposal windows. After a user disposes of waste, the invention closes a closing plate. This closing plate triggers a linkage to activate a drive assembly. Simultaneously, the drive assembly moves a movable frame along a support column in a long groove, while simultaneously activating the spray pipe's chemical supply path. This allows disinfectant to continuously spray from nozzles on the movable frame, providing comprehensive mobile spray disinfection to the entire disposal window area and the surrounding area. This effectively removes bacteria adhering to the window area, neutralizes odors, reduces mosquito breeding, and improves the sanitary environment around the waste room.

Description

Technical Field

[0001] This invention relates to the field of waste treatment, specifically to an intelligent waste room with a gate-controlled spray disinfection linkage mechanism. Background Technology

[0002] Smart garbage collection stations, as important facilities for improving garbage collection efficiency and the community environment, have been widely used in many public areas. Currently, these smart garbage collection stations are usually equipped with multiple disposal windows with covers. Users need to manually open the covers when disposing of garbage and close them after disposal. However, in actual use, since the disposal window is the only direct contact interface between the user and the garbage collection station, and the inside of the garbage collection station is in a high-humidity, high-organic-pollution environment for a long time, bacteria, mold and various stains are easily attached to the inner wall of the window, the edge of the cover and the surrounding area. When users open or close the cover, they will inevitably come into close contact with these contaminated areas, posing a health risk of cross-infection. To alleviate this problem, existing garbage collection stations are generally equipped with disinfection devices, but most of them spray disinfectant agents at fixed time intervals (such as every few hours) or fixed time periods, either in the whole space or at fixed points. This static "fixed-time, fixed-location" disinfection model is completely disconnected from the actual opening and closing of the garbage disposal window, making it impossible to form an effective linkage control. The period immediately following each garbage disposal is a high-risk time for the release of harmful gases from the garbage room, the spread of bacteria and viruses via aerosols, and the aggravation of contamination in the window area. Existing timed disinfection systems cannot respond to this immediate disinfection need, often only addressing the issue after bacteria have already adhered and odors have spread. This not only wastes disinfectant but also easily leads to bacterial residue and odor spread due to the inability to complete targeted disinfection promptly after each garbage disposal, affecting the sanitary environment around the garbage room.

[0003] To address this, a smart garbage room with a gate-controlled spray disinfection linkage mechanism is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent garbage room with a gate-controlled spray disinfection linkage mechanism to solve the problem that the static disinfection mode is completely disconnected from the actual opening and closing action of the garbage disposal window, which not only wastes disinfection agents, but also easily leads to bacterial residue and odor spread due to the inability to complete targeted disinfection in time after each garbage disposal, affecting the sanitary environment around the garbage room.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A smart garbage room with a gate-controlled spray disinfection linkage mechanism includes a garbage room body. Multiple disposal windows are opened on one side of the garbage room body. Multiple garbage bins are placed inside the garbage room body, with the garbage bins located on one side of the disposal windows. A closing plate is slidably connected to the disposal windows. Multiple elongated slots are opened on the garbage room body, distributed on both sides of the disposal windows. Support columns are fixedly installed in each elongated slot. A movable frame is slidably connected to the support columns. Multiple evenly spaced spray nozzles are fixedly installed on the movable frame. A connecting rod is fixedly installed on one side of the closing plate. A drive assembly is installed inside the garbage room body. The drive assembly is connected to the connecting rod and the spray nozzles. When the closing plate is closed, the drive assembly is driven to operate via the connecting rod. The drive assembly moves the movable frame and simultaneously drives the spray nozzles to spray.

[0006] Currently, smart garbage collection stations in public areas require users to open the cover of the disposal window to dispose of garbage and close it afterward. However, this exposes users to bacteria and grime adhering to the window, and the inside of the station can easily accumulate odors and breed mosquitoes and germs. Existing disinfection devices mostly spray disinfectant at fixed times and locations, failing to integrate with the door control switch. This not only wastes disinfectant but also results in bacterial residue and odor spread due to the inability to perform targeted disinfection after each disposal, affecting the surrounding environment. Furthermore, existing disinfection mechanisms often cannot dynamically spray in sync with the window opening and closing, resulting in incomplete coverage of the window area and garbage disposal entrance, limiting the effectiveness of disinfection. Therefore, this invention utilizes a drive component that integrates with the closing plate, providing… When the system is in use, after the user disposes of garbage and closes the closing plate of the disposal window, the closing plate moves the connecting rod inward synchronously. The connecting rod triggers the drive component to start. While the drive component moves the moving frame back and forth along the support column in the long groove, it also simultaneously connects the supply path of the spray pipe, allowing the disinfectant to be continuously sprayed from the nozzles on the moving frame. The nozzles move with the moving frame, which can carry out full-range mobile spray disinfection of the entire disposal window area and the surrounding area of ​​the entrance. After each garbage disposal, a targeted disinfection is automatically completed, eliminating the need for additional spraying at fixed times and locations. This avoids the ineffective waste of disinfectant, and can also promptly remove germs attached to the window area, neutralize the drifting odors, and reduce the breeding of mosquitoes. The dynamic mobile spray has a larger coverage area, solving the problem of dead corners in the disinfection of fixed nozzles, and effectively improving the sanitary environment around the garbage room.

[0007] Preferably, when the closing plate slides down to close the delivery window, the original position of the moving frame is located below the delivery window. The original position of the moving frame is set on the side where the closing plate closes the delivery window, and the direction in which the driving component drives the nozzle to spray is opposite to the direction in which the closing plate closes the delivery window.

[0008] The advantage of this setup is that once the user finishes disposing of the garbage and closes the closing plate, the linkage mechanism can be directly triggered, causing the nozzles to move from the bottom to the top of the disposal window. Along the movement trajectory of the closing plate, the nozzles simultaneously spray and disinfect the disposal window area and the garbage just placed in the bin. This allows for immediate treatment of any residual odors and germs after garbage disposal, preventing odors from spreading outside the garbage room. Simultaneously, the moving nozzles cover the entire disposal window area, leaving no blind spots and ensuring effective disinfection. The original position of the moving frame is set on the side where the closing plate closes the disposal window, ensuring the frame can move to the designated location for disinfection as quickly as possible. Furthermore, the entire disinfection process is automatically triggered by the closing action of the closing plate, requiring no additional sensors or manual operation from the user. The linkage logic is simple, resulting in a lower failure rate and reducing the overall manufacturing cost of the mechanism.

[0009] Preferably, the drive assembly includes a mounting box, which is fixedly installed inside the garbage room body. A first gear is rotatably connected inside the mounting box, and a first rack meshes with the first gear on one side. A connecting rod extends into the mounting box and is fixedly installed with the first rack. A second gear is rotatably connected inside the mounting box, and a first one-way ratchet is installed between the first gear and the second gear. The inner ring of the first one-way ratchet is fixedly installed with the first gear, and the outer ring of the first one-way ratchet is fixedly installed with the second gear. A piston cylinder is fixedly installed inside the mounting box, and a connecting plate is fixedly installed on the piston rod of the piston cylinder. A compression spring is installed between the connecting plate and the inner wall of the mounting box. A second rack is installed on the connecting plate, and the second rack meshes with the second gear. An inlet pipe and an outlet pipe are fixedly installed on the piston cylinder, and a one-way valve is installed on both the inlet pipe and the outlet pipe. The inlet pipe is connected to a storage tank, and the outlet pipe is connected to multiple nozzles. A pusher is installed inside the mounting box, and the pusher is connected to a moving frame and the second rack. The pusher pushes the moving frame to move up and down.

[0010] With the above structure, when the closing plate of the garbage room body is opened, the closing plate drives the first rack to move upward via the connecting rod. The first rack drives the first gear to rotate. At this time, due to the first one-way ratchet, it cannot drive the second gear on one side to rotate, that is, it cannot drive the second rack to move upward and the piston cylinder to pump liquid. When the operator finishes disposing of garbage and closes the closing plate, the closing plate drives the first rack to move downward via the connecting rod. The first gear drives the second gear to rotate together. The second gear, due to the first one-way ratchet, drives the second rack to move. The second rack pushes the piston rod to stretch the space inside the piston cylinder, while compressing the spring to store force, and then pumping the disinfectant liquid in the storage tank through the inlet. The liquid is delivered to the piston cylinder. When the main door of the garbage room is closed, the first rack and the first gear separate, causing the second rack to move in the opposite direction due to the stored compression spring, which in turn drives the second gear to rotate in the opposite direction. Because the first rack and the first gear are separated, the second gear will not drive the first rack to move. The compression spring pushes the piston rod in the piston cylinder to move down, causing the disinfectant to be sprayed through the nozzle. At the same time, the pusher also drives the moving frame to move, carrying out all-round spraying, waiting for the next closing plate to open to trigger disinfection. This achieves the linkage effect of disinfection as soon as the door is opened, without the need for additional manual or electronic module triggering. The structure is stable and reliable, reducing the cost and failure rate of the garbage room disinfection mechanism.

[0011] Preferably, the pushing component includes two rubber rollers, which are rotatably mounted in the mounting box. A second one-way ratchet is installed between the two rubber rollers. The inner and outer rings of the second one-way ratchet are fixedly mounted to the two rubber rollers, respectively. A long rod is slidably connected inside the mounting box. One end of the long rod is fixedly mounted to the moving frame. The two rubber rollers abut against the back of the long rod and the second rack, respectively.

[0012] When the delivery window is closed, the linkage moves accordingly, sequentially driving the first rack, the first gear, and the second gear to transmit power, which in turn drives the second rack to move upward in the vertical direction. As the second rack moves upward, it continuously applies pressure to the compression spring, causing it to be squeezed. This process pushes the piston rod inside the piston cylinder to retract into the cylinder. Meanwhile, during the movement of the second rack, its surface comes into contact with the rubber roller. The friction between them drives the connected second one-way ratchet to engage, further propelling the long rod upwards. The rising of the long rod ultimately pushes the moving frame upwards, completing the disinfection operation. Since the upward distance of the moving frame is related to the degree of opening of the closing plate, and the final position of the moving frame is related to the final opening height of the closing plate, disinfection is only performed on the passageway in the area where the delivery window is open. When the second rack moves to its final position and disengages from the rubber roller, the long rod and the connected moving frame will return to their original positions due to gravity. Simultaneously, the friction between the rubber roller and the two components pushes the long rod forward, ensuring that even if the moving frame is prevented from moving upwards due to external factors, the second rack can still continue to move without interference. This also ensures that the moving frame can continue to operate normally after the external factors disappear.

[0013] When the delivery window is opened, the closing plate drives the connecting rod to move in the opposite direction, at which point the second rack moves in the opposite direction as well. During this reverse movement, the second one-way ratchet slips and cannot transmit motion to the long rod. Therefore, the long rod will not move downwards or in the opposite direction, and the connected moving frame will not rise accordingly. This design ensures that the moving frame will not rise when the operator opens the delivery window, thus avoiding obstruction or interference to the operator.

[0014] Preferably, a swing plate is rotatably connected inside the mounting box, a torsion spring is installed at the rotatable connection of the swing plate, a retaining tooth is rotatably connected to one end of the swing plate, the retaining tooth cooperates with the second gear, a limiting piece is fixedly installed on the swing plate to limit the rotation direction of the retaining tooth, and a pressure column is slidably connected inside the delivery window. When the delivery window is closed, the pressure column is pushed to squeeze the swing plate below.

[0015] When the user opens the dispensing window, the closing plate moves upward synchronously with the upward movement of the dispensing window. At this time, the oscillating plate causes the locking teeth at its end to droop due to gravity or the action of the torsion spring, forming a meshing state with the second gear. Due to the structural limitation of the limit plate, the second gear can only rotate in one direction at this time, that is, it can only drive the second rack to move upward, thereby driving the piston cylinder to perform the liquid pumping action. It cannot rotate in the opposite direction to move the second rack downward for spraying. This effectively prevents the situation where, when the closing plate is closed, it is squeezed downward by the compression spring, causing the first rack to move upward through the linkage of the second gear and the first gear, thus causing the closing plate to slowly rise. When the closing plate completely closes the dispensing window, the closing plate in the lower position will exert a squeezing effect on the oscillating plate, causing the locking teeth at the other end of the oscillating plate to lift upward, thereby disengaging from the second rack and allowing the second gear to rotate freely. This means that the second rack can move downward at this time. This structure ensures that the second rack can only drive the moving frame to move and the nozzle to perform the spray disinfection function after the closing plate completely closes the dispensing window, ensuring reliable control of the operation sequence.

[0016] Preferably, the connecting plate has a through groove, the second rack is slidably connected in the through groove, and two limiting rings are fixedly installed on the second rack. The two limiting rings are respectively located on both sides of the connecting plate, and one end of the compression spring abuts against the limiting ring.

[0017] In actual operation, the design of the limiting ring allows for a certain movable gap between the second rack and the connecting plate. This ensures that when the second rack moves downwards and lowers the connecting plate to perform the liquid pumping action, the second rack must first move downwards a preset distance before effectively driving the connecting plate to begin displacement and initiating the spraying operation. Since the second rack and the moving frame are interconnected, during this process, the moving frame first moves upwards, causing the nozzle to rise and move away from the handle located on one side before spraying begins. This design effectively prevents the handle from being splashed with liquid during spraying, avoids dust accumulation due to moisture, keeps the handle clean and dry, and prevents users from littering due to handle contamination.

[0018] Preferably, a guide platform is fixedly installed on the outer wall of the garbage room body. The guide platform is inclined towards the disposal window. An elongated groove is formed on the guide platform, and the elongated groove cooperates with the movable frame. The distance between the nozzle and the disposal window is A = 10cm. <A<20cm。

[0019] The guide platform directs the garbage, allowing it to slide smoothly into the disposal window and restricting its trajectory to prevent it from falling outside the garbage room and increasing the workload of cleaning staff. The distance between the nozzle and the disposal window ensures that the disinfection area covers the garbage entry point, avoiding blind spots, while preventing splashing of disinfectant onto garbage disposal personnel due to insufficient distance, ensuring safety. A distance greater than 10cm between the nozzle and the disposal window ensures the disinfectant is fully applied to the space around the window, guaranteeing effective disinfection. Conversely, a distance less than 20cm prevents incomplete disinfection of the area around the window due to excessive distance.

[0020] Preferably, a nozzle is installed inside the garbage room body, the nozzle is positioned above the garbage bin, a piston cylinder is fixedly installed inside the mounting box, the movable end of the piston cylinder is fixedly installed to the connecting plate, two liquid passage pipes are fixedly installed on the piston cylinder, each of the two liquid passage pipes is equipped with a one-way valve, one of the liquid passage pipes is connected to the nozzle, and the other liquid passage pipe is connected to the liquid storage tank at the bottom of the handwashing sink.

[0021] When the connecting plate moves back and forth, it drives the moving end of the piston cylinder to move back and forth synchronously. Through the cooperation of two one-way valves, the disinfectant liquid in the storage tank is continuously drawn to the nozzle and sprayed out to atomize and disinfect the area above the garbage bin. The disinfection operation is automatically completed during the garbage disposal process, without the need for an additional independent drive source to drive the disinfection system. At the same time, the inside of the garbage bin is disinfected by the hand sanitizer left by other personnel after washing their hands in the sink. This greatly reduces the energy consumption and manufacturing cost of the overall structure of the garbage room, while ensuring the timeliness of disinfection and effectively reducing the spread of odors and the growth of germs in the garbage room.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. After the user disposes of the garbage, the closing plate is closed. The closing plate drives the linkage to trigger the drive component to start. While the drive component moves the moving frame back and forth along the support column in the long groove, it also simultaneously connects the supply channel of the spray pipe, allowing the disinfectant to be continuously sprayed from the nozzles on the moving frame. This can carry out full-range mobile spray disinfection of the entire disposal window area and the area around the entrance, timely remove germs attached to the window area, neutralize the drifting odors, reduce the breeding of mosquitoes, and effectively improve the sanitary environment around the garbage room.

[0023] 2. After the closing plate completely closes the dispensing window, the closing plate in the lower position will exert a squeezing effect on the swing plate, causing the locking teeth at the other end of the swing plate to lift upward, thereby disengaging from the second rack and allowing the second gear to rotate freely. This means that the second rack can move downward at this time. This structure ensures that the second rack can only push the moving frame to move and the nozzle to perform the spray disinfection function after the closing plate completely closes the dispensing window, ensuring reliable control of the operation sequence.

[0024] 3. The design of the limiting ring allows the second rack to have a certain movable gap on the connecting plate. This ensures that when the second rack moves downward and drives the connecting plate down to perform the liquid pumping action, the second rack must first move downward a preset travel distance. Since the second rack and the moving frame are connected to each other, the nozzle is raised and moved away from the handle on one side before spraying begins. This design effectively prevents the handle from being splashed with liquid during spraying, avoids dust accumulation due to moisture, and keeps the handle clean and dry. Attached Figure Description

[0027] Please see Figures 1 to 8 This invention provides an intelligent garbage room with a gate-controlled spray disinfection linkage mechanism, the technical solution of which is as follows: A smart garbage room with a gate-controlled spray disinfection linkage mechanism includes a garbage room body 1. Multiple disposal windows 2 are opened on one side of the garbage room body 1. Multiple garbage bins 9 are placed inside the garbage room body 1, with the garbage bins 9 located on one side of the disposal windows 2. A closing plate 4 is slidably connected to the disposal windows 2. Multiple elongated grooves 3 are opened on the upper part of the garbage room body 1, distributed on both sides of the disposal windows 2. Support columns 10 are fixedly installed in each elongated groove 3. A movable frame 5 is slidably connected to the support columns 10. Multiple evenly spaced spray nozzles 35 are fixedly installed on the movable frame 5. A connecting rod 11 is fixedly installed on one side of the closing plate 4. A drive assembly is installed inside the garbage room body 1, connected to the connecting rod 11 and the spray nozzles 35. After the closing plate 4 is closed, the drive assembly is driven by the connecting rod 11. The drive assembly moves the movable frame 5 while simultaneously driving the spray nozzles 35 to spray.

[0028] When the closing plate 4 slides down to close the delivery window 2, the original position of the moving frame 5 is located below the delivery window 2. The original position of the moving frame 5 is set on the side where the closing plate 4 closes the delivery window 2, and the direction in which the driving component drives the nozzle 35 to spray is opposite to the direction in which the closing plate 4 closes the delivery window 2.

[0029] The drive assembly includes a mounting box 8, which is fixedly installed inside the garbage room body 1. A first gear 15 is rotatably connected inside the mounting box 8. A first rack 13 meshes with the first gear 15 on one side. A connecting rod 11 extends into the mounting box 8 and is fixedly installed with the first rack 13. A second gear 14 is rotatably connected inside the mounting box 8. A first one-way ratchet 33 is installed between the first gear 15 and the second gear 14. The inner ring of the first one-way ratchet 33 is fixedly installed with the first gear 15, and the outer ring of the first one-way ratchet 33 is fixedly installed with the second gear 14. A piston is fixedly installed inside the mounting box 8. A connecting plate 19 is fixedly installed on the piston rod of the piston cylinder 21. A compression spring 25 is installed between the connecting plate 19 and the inner wall of the mounting box 8. A second rack 17 is installed on the connecting plate 19, and the second rack 17 meshes with the second gear 14. An inlet pipe 22 and an outlet pipe 23 are fixedly installed on the piston cylinder 21. A one-way valve 24 is installed on both the inlet pipe 22 and the outlet pipe 23. The inlet pipe 22 is connected to a storage tank, and the outlet pipe 23 is connected to multiple nozzles 35. A pusher is installed inside the mounting box 8. The pusher is connected to the moving frame 5 and the second rack 17. The pusher pushes the moving frame 5 to move up and down.

[0030] The pusher includes two rubber rollers 20, which are rotatably mounted in the mounting box 8. A second one-way ratchet 34 is installed between the two rubber rollers 20. The inner and outer rings of the second one-way ratchet 34 are fixedly mounted to the two rubber rollers 20 respectively. A long rod 12 is slidably connected in the mounting box 8. One end of the long rod 12 is fixedly mounted to the moving frame 5. The two rubber rollers 20 abut against the back of the long rod 12 and the second rack 17 respectively.

[0031] Inside the mounting box 8, a swing plate 16 is rotatably connected. A torsion spring is installed at the rotatable connection of the swing plate 16. One end of the swing plate 16 is rotatably connected to a locking tooth 31, which cooperates with the second gear 14. A limiting piece 32 is fixedly installed on the swing plate 16 to limit the rotation direction of the locking tooth 31. A pressure column 30 is slidably connected inside the delivery window 2. When the delivery window 2 is closed, the pressure column 30 is pushed to squeeze the swing plate 16 below.

[0032] A through groove is provided on the connecting plate 19, and the second rack 17 is slidably connected in the through groove. Two limiting rings 18 are fixedly installed on the second rack 17. The two limiting rings 18 are located on both sides of the connecting plate 19 respectively, and one end of the compression spring 25 abuts against the limiting ring 18.

[0033] A guide platform 6 is fixedly installed on the outer wall of the garbage room body 1. The guide platform 6 is inclined to one side of the disposal window 2. A long groove is opened on the guide platform 6, and the long groove cooperates with the moving frame 5. The distance between the nozzle 35 and the disposal window 2 is A = 10cm. <A<20cm。

[0034] A nozzle 7 is installed inside the main body 1 of the garbage room. The nozzle 7 is located above the garbage bin 9. A piston cylinder 28 is fixedly installed inside the mounting box 8. The movable end of the piston cylinder 28 is fixedly installed with the connecting plate 19. Two liquid pipes 26 are fixedly installed on the piston cylinder 28. A one-way valve 24 is installed on each of the two liquid pipes 26. One liquid pipe 26 is connected to the nozzle 7, and the other liquid pipe 26 is connected to the liquid storage tank at the bottom of the handwashing sink.

[0035] In practical use, when the closing plate 4 of the garbage room body 1 is opened for garbage disposal, the closing plate 4 drives the first rack 13 to move upward via the connecting rod 11. The first rack 13 drives the first gear 15 to rotate. At this time, due to the first one-way ratchet 33, it cannot drive the second gear 14 on one side to rotate, that is, it cannot drive the second rack 17 to move upward and the piston cylinder 21 to pump liquid. The closing plate 4 drives the first rack 13 to move downward via the connecting rod 11. When a user disposes of garbage and closes the closing plate 4 of the disposal window 2, the closing plate 4 drives the connecting rod 11 to move inward synchronously. The first gear 15 drives the second gear 14 to rotate together. The second gear 14 drives the second rack 17 to move through the first one-way ratchet 33. The second rack 17 pushes the piston rod to stretch the space inside the piston cylinder 21. At the same time, the spring 25 is compressed and stored, and the disinfectant in the storage tank is transported to the piston cylinder 21 through the inlet pipe 22. When the garbage room body 1 door is closed, when the user opens the disposal window 2, the closing plate 4 moves upward synchronously with the upward movement of the disposal window 2. At this time, the swing plate 16 drives the locking tooth 31 at its end to droop due to gravity or the action of the torsion spring, forming a meshing state with the second gear 14. Due to the structural limitation of the limit plate 32, the first gear 14 is engaged with the second gear 14. The second gear 14 can only rotate in one direction, that is, it can only drive the second rack 17 to move upward, thereby driving the piston cylinder 21 to perform the liquid pumping action. It cannot rotate in the opposite direction to make the second rack 17 move downward for spraying. This effectively prevents the situation where, when the closing plate 4 moves down to close the dispensing window 2, the stretched compression spring 25 is squeezed downward, and through the linkage of the second gear 14 and the first gear 15, it drives the first rack 13 to move upward, thereby causing the closing plate 4 to slowly rise. When the closing plate 4 completely closes the dispensing window 2, the closing plate 4 in the lower position will exert a squeezing effect on the swing plate 16, causing the locking tooth 31 at the other end of the swing plate 16 to lift upward, thereby disengaging from the contact with the second rack 17, allowing the second gear 14 to rotate freely. This means that the second rack 17 can move downward at this time.

[0036] At this time, the first rack 13 and the first gear 15 are separated, causing the second rack 17 to move in the opposite direction by the stored compression spring 25, which drives the second gear 14 to rotate in the opposite direction. Because the first rack 13 and the first gear 15 are separated, the second gear 15 will not drive the first rack 13 to move. The compression spring 25 pushes the piston rod in the piston cylinder 21 to move down, so that the disinfectant is sprayed through the nozzle 35. At the same time, the pusher will also drive the moving frame 5 to move, so as to spray in all directions, waiting for the next time the closing plate 4 is opened to trigger disinfection, thus realizing the linkage effect of disinfection when the door is opened.

[0037] In actual operation, the design of the limiting ring 18 allows the second rack 17 to have a certain movable gap on the connecting plate 19. This ensures that when the second rack 17 moves downward and drives the connecting plate 19 down to perform the liquid pumping action, the second rack 17 must first move downward a preset stroke distance before it can effectively drive the connecting plate 19 to begin displacement and start the spraying operation. Since the second rack 17 and the moving frame 5 are interconnected, during this process, the moving frame 5 will first move upward, causing the nozzle 35 to rise and move away from the handle located on one side before spraying begins. This design effectively prevents the handle from being splashed with liquid during spraying, avoids dust accumulation due to moisture, keeps the handle clean and dry, and prevents users from littering due to handle contamination.

[0038] Meanwhile, during the movement of the second rack 17, its surface will come into contact with the rubber roller 20. With the help of the friction between the two, the second one-way ratchet 34 connected to it will engage and drive, thereby further driving the long rod 12 to move upward. The rise of the long rod 12 will eventually push the moving frame 5 to lift, completing the disinfection operation. Of course, since the upward movement distance of the moving frame 5 is related to the opening degree of the closing plate 4, and the final position of the moving frame 5 is related to the final opening height of the closing plate 4, disinfection is only carried out on the channel of the opening area of ​​the delivery window 2. Of course, when the second rack 17 moves to the final position and disengages from the rubber roller 20, the long rod 12 and the connected moving frame 5 will return to their original positions due to gravity. At the same time, the friction between the rubber roller 20 and the two will push the long rod 12 to move, ensuring that when the moving frame 5 is prevented from moving upward due to external reasons, the second rack 17 can still continue to move without interference. Of course, it also ensures that the moving frame 5 can maintain normal operation after the external reasons disappear.

[0039] The guide platform 6 guides the disposed waste, allowing it to slide more smoothly into the disposal window 2. It restricts the waste disposal trajectory, preventing waste from falling outside the main body of the waste room 1 and increasing the workload of cleaning staff. It limits the distance between the nozzle 35 and the disposal window 2, ensuring that the disinfection range covers the waste entry channel, avoiding blind spots, and preventing disinfection liquid from splashing onto waste disposal personnel due to excessive distance, thus ensuring safety. At the same time, the distance between the nozzle 35 and the disposal window 2 is greater than 10cm to ensure that the disinfectant sprayed by the nozzle 35 can fully spray the space at the disposal window 2, ensuring that the disinfectant can disinfect the space at the disposal window 2. Of course, the distance between the nozzle 35 and the disposal window 2 is less than 20cm to avoid the nozzle 35 being too far away and unable to completely disinfect the space at the disposal window 2.

[0040] When the connecting plate 19 moves back and forth, it drives the moving end of the piston cylinder 28 to move back and forth synchronously. Through the cooperation of the two one-way valves 24, the disinfectant liquid in the storage tank is continuously drawn to the nozzle 7 and sprayed out from the nozzle 7 to atomize and disinfect the area above the garbage bin 9. The disinfection operation is automatically completed during the garbage disposal process without the need for an additional independent drive source to drive the disinfection system. At the same time, the inside of the garbage bin 9 is disinfected by the hand sanitizer left by other personnel after washing their hands in the sink. This greatly reduces the energy consumption and manufacturing cost of the overall structure of the garbage room 1, while ensuring the timeliness of disinfection and effectively reducing the spread of odor and the growth of bacteria in the garbage room 1.

[0041] The specific embodiment of the present invention has been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the embodiments described above. For those skilled in the art, various changes, modifications, substitutions, and variations made to these embodiments without departing from the principles and ideas of the present invention should still fall within the protection scope of the present invention.
