Description

Technical Field

[0001] This invention relates to the field of sterilization and disinfection equipment technology, specifically to an intelligent sterilization and disinfection linkage device and disinfection method for elevators. Background Technology

[0002] Elevators are high-traffic areas, and current ultraviolet disinfection methods have the following problems: First, ultraviolet light cannot be used to expose people for extended periods, as it can easily cause dizziness and nausea; second, ultraviolet sterilization is a long-term process, and since elevators are empty for very short periods, rapid disinfection is not possible; third, the purpose of disinfection is to prevent the spread of viruses between people, and rapid disinfection is needed during transfers to achieve the desired effect. To address these issues, the following solutions are proposed.

[0003] Elevators are indispensable in modern urban life, widely used in shopping malls, hospitals, office buildings, and residential buildings. For enclosed spaces like elevators, the high density of people increases the risk of infectious disease transmission. Therefore, effective epidemic prevention and control measures for elevators are crucial, such as regular disinfection. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides an intelligent sterilization and disinfection linkage device and disinfection method for elevators, including an elevator mechanism and an equipment shell. The equipment shell has a base plate fixedly connected to the bottom of its inner wall, and the top of the base plate has several disinfection pools. This mechanism provides an installation position for subsequent mechanisms and plays a stabilizing role during operation, ensuring normal operation of the equipment and avoiding problems such as bumps.

[0005] The pressing linkage mechanism includes a sliding rail fixedly connected to the top of the equipment base plate, a limiting plate fixedly connected to the top of the sliding rail, and several telescopic springs fixedly connected to the top of the equipment base plate.

[0006] The closed pressurization mechanism includes a hydraulic tank fixedly connected to the top of the inner wall of the equipment housing. Several limiting frames are fixedly connected to the top outer wall of the hydraulic tank, and a closing plate is slidably connected to the inner wall of the limiting frames.

[0007] Preferably, the elevator mechanism also includes a sewage tank located on the top of the equipment base plate. Several suction tanks are provided on the top of the equipment base plate, and the inner walls of the suction tanks are connected to the inner wall of the disinfection tank. A sewage cover is fixedly connected to the inner wall of the sewage tank. This device uses the passenger weight as the power output, so that the equipment can be disinfected in time after a group of people have ridden, to avoid the spread of viruses. Moreover, through the linkage of equipment components, the disinfectant is controlled to be applied when the elevator is empty. The above disinfection method is equivalent to ultraviolet disinfection, which is faster and suitable for the noisy working environment of elevators.

[0008] Preferably, the elevator mechanism also includes a sewage hose that runs through the top of the sewage cover, a disinfection plate that is fixedly connected to the inner wall of the disinfection pool, and a disinfection injection pipe that runs through the top outer wall of the disinfection plate. The present invention is internally provided with an equipment shell, an equipment base plate, and a sewage cover. The tight fit between the equipment shell and the equipment base plate increases the stability of the equipment during operation and helps to reduce the shaking generated by the equipment shell during operation.

[0009] Preferably, the pressing linkage mechanism further includes a sliding plate slidably connected to the inner wall of the sliding track, a collecting plate fixedly connected to the top of the sliding plate, and a screening plate fixedly connected to the inner wall of the sliding plate.

[0010] Preferably, the pressing linkage mechanism also includes several pressing tubes fixedly connected to the top of the equipment base plate, and pressing plates are slidably connected to the inner walls of the pressing tubes. Pressing columns are fixedly connected to the top of the pressing plates. When the number of people is high, the number of times the disinfectant is applied increases, and some disinfectant will accumulate inside the elevator. To address this issue, a collection plate is installed inside the equipment. After the liquid is sprayed from the top, the excess liquid penetrates the screening plate and reaches the surface of the collection plate, and then reaches the sewage tank through the sewage hose, thus preventing the elevator interior from becoming too damp and affecting the service life of the iron components inside the elevator.

[0011] Preferably, the pressing linkage mechanism also includes an output pipe connected through the outer wall of the pressing tube, a return spring fixedly connected to the bottom of the pressing plate, a one-way valve one fixedly connected to the inner wall of the suction tank, and a one-way valve two fixedly connected to the inner wall of the output pipe. When a person steps on the screening plate, the screening plate converts the weight it bears into power, which squeezes the pressing column through the collecting plate, and the pressing column drives the pressing plate to move downward, creating a negative pressure inside the pressing tube. The liquid inside the disinfection pool is then drawn in through the suction tank. The disinfectant at the bottom is transferred to the top by the control of the two one-way valves, one and two. This design reduces the number of electronic components such as motors and electric telescopic rods, and uses passenger pressure to achieve liquid transfer, improving the practicality of the equipment and reducing the failure rate of the equipment.

[0012] Preferably, the closed pressurization mechanism further includes a limiting spring fixedly connected to the outer wall of the limiting frame. The bottom of the limiting spring is fixedly connected to the top of the closed plate. Several trolley chains are fixedly connected to the top of the sliding plate. A sliding frame is fixedly connected to the end of the trolley chains away from the sliding plate. The bottom of the sliding frame is slidably connected to the top of the hydraulic tank. A moving plate is fixedly connected to the top of the sliding frame. An atomizer is connected through the bottom of the hydraulic tank. Small springs are fixedly connected to the outer wall of the sliding frame. The end of the small springs away from the sliding frame is fixedly connected to the side wall of the hydraulic tank. After the above liquid transfer, disinfection is achieved. The liquid reaches the hydraulic tank through the output pipe. At this time, the trolley chain is pulled by the sliding plate, and the moving plate cuts off the liquid flow path of the atomizer. The top hydraulic tank is in a pressurized state. When the last passenger leaves, the screening plate loses pressure, the extension spring and the return spring release mechanical power, and the small spring pulls the moving plate, so that the through hole of the moving plate fits with the atomizer. The liquid inside the hydraulic tank is sprayed into the elevator through the atomizer to achieve rapid disinfection. The spray-like liquid can suppress a large number of bacteria floating in the air, achieving the effect of air purification while achieving disinfection.

[0013] A disinfection method for an intelligent sterilization and disinfection linkage device in an elevator includes the following steps:

[0014] S1: Install the equipment inside the elevator and inject disinfectant into the disinfection pool through the disinfection injection pipe, and wait for passengers to board the elevator;

[0015] S2: When passengers enter the elevator, they step on the screening plate to provide pressure to the pressing plate and conduct the liquid upward through the output pipe. The moving plate is affected by the trolley chain, which cuts off the transmission line of the atomizer and opens the flow path of the closed plate.

[0016] S3: After personnel arrive at the location, the screening plate loses pressure, the liquid inside the atomizer and hydraulic tank flows, and enters the liquid mist disinfection process, while the sealing plate seals the transmission of the output pipe.

[0017] The present invention has the following beneficial effects:

[0018] (1) When personnel step on the screening plate, the screening plate converts the gravity it bears into power. The collecting plate squeezes the pressing column, and the pressing column drives the pressing plate to move downward, creating a negative pressure inside the pressing tube. The liquid inside the disinfection pool is drawn in through the suction tank. The disinfectant at the bottom is transferred to the top through the control of two one-way valves, one-way valve one and one-way valve two. This design reduces electronic components such as motors and electric telescopic rods, and uses passenger pressure to achieve liquid transfer, improving the practicality of the equipment and reducing the failure rate of the equipment.

[0019] (2) After the above-mentioned liquid transmission, the disinfectant reaches the hydraulic tank through the output pipe. At this time, the trolley chain is pulled by the sliding plate, the moving plate cuts off the liquid flow path of the atomizer, and the top hydraulic tank is in a pressurized state. When the last passenger leaves, the screening plate loses pressure, the extension spring and the return spring release mechanical power, and the small spring pulls the moving plate, so that the through hole of the moving plate fits with the atomizer. The liquid inside the hydraulic tank is sprayed into the elevator through the atomizer to achieve a rapid disinfection state. The spray-like liquid can suppress a large number of bacteria floating in the air, achieving the effect of disinfection and air purification at the same time.

[0020] (3) The present invention enables the equipment to achieve rapid disinfection through the linkage of the above components. When the number of people is dense, the number of disinfection operations increases and some disinfection will accumulate inside the elevator. To address the above problems, a collection plate is installed inside the equipment. After the liquid is sprayed from the top, the excess liquid is equivalent to penetrating the screening plate to reach the surface of the collection plate and then reaching the sewage tank through the sewage hose, thus avoiding the elevator interior from being too damp and affecting the service life of the ironware inside the elevator.

[0021] (4) This invention uses passenger weight as power output, so that the equipment can be disinfected in time after a group of people have boarded, thus avoiding the spread of the virus. Furthermore, through the linkage of equipment components, the disinfectant is controlled to be disinfected when the elevator is empty. The above disinfection method is equivalent to ultraviolet disinfection, which is faster and more suitable for the noisy working environment of elevators. Attached Figure Description

[0036] The closed pressurization mechanism 3 includes a hydraulic tank 301 fixedly connected to the top of the inner wall of the equipment housing 101. Several limiting frames 302 are fixedly connected to the top outer wall of the hydraulic tank 301, and a closing plate 303 is slidably connected to the inner wall of the limiting frame 302.

[0037] The elevator mechanism 1 also includes a sewage tank 104 located on the top of the equipment base plate 102. Several suction inner grooves 105 are provided on the top of the equipment base plate 102. The inner walls of the suction inner grooves 105 are connected to the inner wall of the disinfection tank 103. A sewage cover 106 is fixedly connected to the inner wall of the sewage tank 104. This device uses the passenger weight as the power output, so that the equipment can be disinfected in time after a group of people have ridden, so as to avoid the spread of the virus. Moreover, through the linkage of equipment components, the disinfectant is controlled to be disinfected again when the elevator is empty. The above disinfection method is equivalent to the ultraviolet disinfection method, which is faster and suitable for the noisy working environment of elevators.

[0038] The elevator mechanism 1 also includes a sewage hose 107 that runs through the top of the sewage cover 106. A disinfection plate 108 is fixedly connected to the inner wall of the disinfection pool 103. A disinfection injection pipe 109 is run through the top outer wall of the disinfection plate 108. The present invention is internally provided with an equipment shell 101, an equipment base plate 102, and a sewage cover 106. The tight fit between the equipment shell 101 and the equipment base plate 102 increases the stability of the equipment during operation and helps to reduce the shaking generated by the equipment shell 101 during operation.

[0039] Example 2, please refer to Figure 4 - Figure 8 The present invention is an intelligent sterilization and disinfection linkage device and disinfection method for elevators. Based on Example 1, the pressing linkage mechanism 2 further includes a sliding plate 204 slidably connected to the inner wall of the sliding track 201. A collection plate 205 is fixedly connected to the top of the sliding plate 204, and a screening plate 206 is fixedly connected to the inner wall of the sliding plate 204.

[0040] The pressing linkage mechanism 2 also includes several pressing tubes 207 fixedly connected to the top of the equipment base plate 102. A pressing plate 208 is slidably connected to the inner wall of the pressing tubes 207. A pressing column 209 is fixedly connected to the top of the pressing plate 208. When the number of people is high, the number of times the disinfectant is applied increases, and some disinfectant will accumulate inside the elevator. To address this issue, a collection plate 205 is installed inside the equipment. After the liquid is sprayed from the top, the excess liquid penetrates the screening plate 206 and reaches the surface of the collection plate 205, and then reaches the inside of the sewage tank 104 through the sewage hose 107, thus preventing the elevator from becoming too damp and affecting the service life of the ironware inside the elevator.

[0041] The pressing linkage mechanism 2 also includes an output pipe 210 that runs through the outer wall of the pressing tube 207.

A one-way valve 212 is fixedly connected to the inner wall of the suction inner tank 105, and a one-way valve 213 is fixedly connected to the inner wall of the output pipe 210. When a person steps on the screening plate 206, the screening plate 206 converts the weight it bears into power, which squeezes the pressing column 209 through the collecting plate 205. The pressing column 209 drives the pressing plate 208 to move downward, creating a negative pressure inside the pressing tube 207. The liquid inside the disinfection pool 103 is then drawn in through the suction inner tank 105. The disinfectant at the bottom is transferred to the top by the control of the two one-way valves, one-way valve 212 and one-way valve 213. This design reduces the number of electronic components such as motors and electric telescopic rods, and uses passenger pressure to achieve liquid transfer, improving the practicality of the equipment and reducing the failure rate of the equipment.

[0042] The closed pressurization mechanism 3 also includes a limiting spring 304 fixedly connected to the outer wall of the limiting frame 302. The bottom of the limiting spring 304 is fixedly connected to the top of the closed plate 303. Several trolley chains 305 are fixedly connected to the top of the sliding plate 204. A sliding frame 306 is fixedly connected to the end of the trolley chain 305 away from the sliding plate 204. The bottom of the sliding frame 306 is slidably connected to the top of the hydraulic tank 301. A moving plate 307 is fixedly connected to the top of the sliding frame 306. An atomizer 308 is connected through the bottom of the hydraulic tank 301. A small spring 309 is fixedly connected to the outer wall of the sliding frame 306. The end of the small spring 309 away from the sliding frame 306 is fixedly connected to the side wall of the hydraulic tank 301. Through the above-mentioned liquid transmission... After delivery, the disinfectant reaches the hydraulic tank 301 through the output pipe 210. At this time, the trolley chain 305 is pulled by the sliding plate 204, and the moving plate 307 cuts off the liquid flow path of the atomizer 308. The top hydraulic tank 301 is in a pressurized state. When the last passenger leaves, the screening plate 206 loses pressure, the extension spring 203 and the return spring 211 release mechanical power, and the small spring 309 pulls the moving plate 307, so that the through hole of the moving plate 307 fits with the atomizer 308. The liquid inside the hydraulic tank 301 is sprayed into the elevator through the atomizer 308 to achieve rapid disinfection. The spray-like liquid can suppress a large number of bacteria floating in the air, achieving the effect of air purification while achieving disinfection.

[0043] The disinfection method of this sterilization and disinfection device includes the following steps:

[0044] S1: Install the equipment inside the elevator and inject disinfectant into the disinfection pool 103 through the disinfection injection pipe 109, and wait for passengers to board the elevator;

[0045] S2: When passengers enter the elevator, they step on the screening plate 206 to provide pressure to the pressing plate 208 and conduct the liquid upward through the output pipe 210. The moving plate 307 is affected by the pull chain 305, which cuts off the transmission line of the atomizer 308 and opens the flow path of the closed plate 303.

[0046] S3: After the personnel arrive at the location, the screening plate 206 loses pressure, the liquid inside the atomizer 308 and the hydraulic tank 301 flows, and enters the liquid mist disinfection process, and the sealing plate 303 seals the transmission of the output pipe 210.

[0047] A specific application of this embodiment is as follows: During operation, the device is installed inside an elevator, and disinfectant is injected into the disinfection pool via a disinfection injection pipe. While waiting for passengers to board, when passengers step on the screening plate 206, the screening plate 206 converts the weight it bears into power, which, through the collecting plate 205, squeezes the pressing column 209. The pressing column 209 then moves the pressing plate 208 downwards, creating a negative pressure inside the pressing pipe 207. This negative pressure is then drawn from the disinfection pool 103 by the suction tank 105. Controlled by two one-way valves, one-way valve 212 and one-way valve 213, the disinfectant at the bottom is transferred to the top. This design reduces the need for motors, electric telescopic rods, and other electronic components, utilizing passenger pressure to achieve liquid transfer, improving the practicality of the equipment and reducing its failure rate. After the liquid transfer, the disinfectant reaches the hydraulic tank 301 through the output pipe 210. The trolley chain 305 is pulled by the sliding plate 204, and the moving plate 307 cuts off the liquid flow path of the atomizer 308. The top hydraulic tank 301 is in a pressurized state. When the last passenger leaves, the screening plate 206 loses pressure, the extension spring 203 and the return spring 211 release mechanical power, and the small spring 309 pulls the moving plate 307, so that the through hole of the moving plate 307 fits with the atomizer 308. The liquid inside the hydraulic tank 301 is sprayed into the elevator through the atomizer 308 to achieve rapid disinfection. When the number of people is high, the number of disinfection operations increases, and some disinfectant will accumulate inside the elevator. To address the above problems, the equipment is equipped with a collection plate 205. After the liquid is sprayed from the top, the excess liquid penetrates the screening plate 206 to reach the surface of the collection plate 205 and then reaches the sewage tank 104 through the sewage hose 107, preventing the elevator interior from becoming too humid and affecting the service life of the iron parts inside the elevator.
