Description

Technical Field

[0001] This utility model relates to the field of elevator disinfection technology, specifically to an elevator car disinfection and ventilation device. Background Technology

[0002] With the continuous advancement of urban-rural integration in my country, farmers' lifestyles have undergone fundamental changes. They have moved from detached courtyards into new urban communities and apartment buildings, which has led to an increase in the number of floors in residential buildings and the growth in the use of elevators in new urban communities. Elevators have become an important means of transportation for people.

[0003] In existing technologies, elevators are public spaces with high population density and mobility, where bacteria and viruses can multiply and spread rapidly, especially during seasonal outbreaks. If you ride in the same elevator as a virus carrier, you may be infected by droplets from their coughs, sneezes, or conversations. Therefore, there is a need for a disinfection device for elevator cars. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an elevator car disinfection and ventilation device. This device is designed to solve the technical problem of the need for an elevator car disinfection device during seasonal viral outbreaks, where passengers may be infected by droplets from the coughs, sneezes, or conversations of virus carriers if they share an elevator with such individuals.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An elevator car disinfection and ventilation device includes a car. A partition is fixedly installed on the upper part of the inner wall of the car, forming a cavity with the car. A disinfection water tank is fixedly installed on the upper surface of the partition and is located in the cavity. A first conduit is conductively connected to one side of the disinfection water tank. A first valve for controlling the opening and closing of the first conduit is provided on the first conduit. A water pump is fixedly installed on the partition, and the first conduit is conductively connected to the water inlet of the water pump. A second conduit is conductively connected to the water outlet of the water pump. The second conduit passes vertically downward through the partition and is conductively connected to a horizontal long strip pipe closed at both ends. Several spray nozzles are opened along the length of the lower part of the long strip pipe, and a first atomizing nozzle is fixedly installed on each of the spray nozzles. A fresh air assembly is fixedly installed on the top of the car. The air supply end of the fresh air assembly passes into the car and supplies air into the car below the partition after passing through the partition.

[0007] Working principle:

[0008] When disinfection of the elevator car is required, the car is empty. At this time, the first valve is opened and the water pump is started simultaneously. The water pump sends the disinfectant water in the disinfection tank to the second conduit through the pump outlet, and then through the second conduit to the long tube. Finally, the long tube delivers the disinfectant water to several first atomizing nozzles. At the same time, the fresh air assembly is activated. The air supply end of the fresh air assembly passes through the partition and delivers fresh air into the car, ensuring that the air in the car is unobstructed.

[0009] The beneficial effects of this utility model are as follows:

[0010] When the elevator is empty, the first valve allows disinfectant from the disinfection tank to be poured into the second conduit, and the disinfectant then enters the pump's intake end. The disinfectant is then sprayed from the pump's outlet onto several first atomizing nozzles. These nozzles ensure that the disinfectant spray covers most of the elevator's area, guaranteeing efficient disinfection. This method effectively disinfects the air inside the elevator car, preventing the rapid growth and spread of bacteria and viruses. Attached Figure Description

Detailed Implementation

[0013] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0014] like Figure 1As shown, an elevator car disinfection and ventilation device includes a car 1. A partition 2 is fixedly installed on the upper part of the inner wall of the car 1, forming a cavity 3 with the car 1. A disinfection water tank 4 is fixedly installed on the upper surface of the partition 2, and the disinfection water tank 4 is located in the cavity 3. A first conduit 5 is conductively connected to one side of the disinfection water tank 4. A first valve 6 for controlling the opening and closing of the first conduit 5 is provided on the first conduit 5. A water pump 22 is fixedly installed on the partition 2, and the first conduit 5 is conductively connected to the inlet end of the water pump 22. A second conduit 7 is conductively connected to the outlet end of the water pump 22. A vertically downward-pointing conduit 7 passes through the partition 2 and is connected to a horizontally closed long strip 8. Several water nozzles 9 are provided along the length of the lower part of the long strip 8, and each of the water nozzles 9 is fixedly equipped with a first atomizing nozzle 10. A fresh air assembly is fixedly installed on the top of the car 1. The fresh air assembly includes a filter box 11, a fan 12, an air duct 13, and an air guide plate 14. The filter box 11 is fixedly installed on the top of the car 1, and an air outlet duct 15 and an air inlet duct 16 are respectively provided on both sides of the filter box 11. The fan 12 is fixedly installed on the top of the car 1 and located on one side of the filter box 11. The air inlet of the filter box 11 is connected to the air outlet duct 15. One end of the air duct 13 is connected to the air outlet of the fan 12, and the other end of the air duct 13 passes vertically downward through the car 1 and the partition 2. The air guide plate 14 is fixedly installed at the other end of the air guide plate 13 and is connected to the air guide plate 13. The air guide plate 14 includes a first disc 17, a second disc 18 and an annular cover 19. The first disc 17 is located above the second disc 18, and the annular cover 19 is connected between the edges of the first disc 17 and the second disc 18. The first disc 17, the second disc 18 and the annular cover 19 form a cylindrical structure with an internal cavity 3. The air duct 13 passes through the first disc 17 and extends into the air guide plate 14; the first disc 17 and the second disc 18 are provided with a number of first circular holes 20 for the first atomizing nozzle 10 to pass through. The first atomizing nozzle 10 passes through the first disc 17 and the second disc 18 in succession. The second disc 18 is provided with a number of second circular holes 21 for ventilation. The air supply end of the fresh air component passes into the car 1. The air supply end of the fresh air component passes through the partition 2 and supplies air into the car 1 below the partition 2. The first circular holes 20 on the first disc 17 and the second disc 18 through which the first atomizing nozzle 10 passes are all provided with sealant.

[0015] When disinfection of the elevator car is required, the car 1 is empty. At this time, the first valve 6 is opened, and the water pump 22 is started simultaneously. The water pump 22 sends the disinfectant water from the disinfectant tank 4 through its outlet to the second conduit 7, which then transmits it to the long pipe 8. Finally, the long pipe 8 distributes the disinfectant water to several first atomizing nozzles 10. Next, the fan 12 is started simultaneously. The air inlet of the fan 12 draws air into the filter box 11. The filtered air is then transmitted from the air outlet of the fan 12 to the air duct 13, and then further... The air is supplied to the second circular hole 21 on the second disc 18, and fresh air is transmitted into the car 1 through several second circular holes 21. At this time, several first atomizing nozzles 10 pass through the first disc 17 and the second disc 18 one after another. Then, the first atomizing nozzles 10 spray disinfectant into the car 1. At the same time, the second circular holes 21 diffuse the disinfectant in the car 1 through the air duct 13. In this way, not only can the car 1 be disinfected, but the disinfectant can also be evenly diffused, improving the sterilization efficiency. In addition, the sealant can reduce air leakage when the air duct 13 delivers air.

[0016] The water pump 22 can quickly pump disinfectant water from the disinfectant tank 4 to the first atomizing nozzle 10, thereby accelerating the disinfection efficiency. The first atomizing nozzle 10 can atomize and expand the disinfectant water, further improving the disinfection efficiency. The fan 12 can further diffuse the disinfectant water sprayed from the first atomizing nozzle 10 into the car 1, accelerating the diffusion of the disinfectant water in the car 1. The air guide plate 14 can ventilate the car 1 while disinfecting it.

[0017] like Figure 1 As shown, it also includes a fixed box 23 with an opening at the top, which is located above the elevator console inside the car 1. The fixed box 23 contains a press-type disinfectant gel 24. A drying box 31 is provided on one side of the car 1. A hot air pipe 32 is provided at the bottom of the drying box 31. The bottom of the hot air pipe 32 passes through the car 1. A long strip-shaped through groove 33 is opened at the bottom of the car 1. A dustproof net 34 is fixedly connected to the inner wall of the long strip-shaped through groove 33.

[0018] The disinfectant gel installed in the fixed box 23 allows passengers to disinfect themselves after pressing the elevator buttons, preventing the spread of viruses. The drying box 31 allows the disinfectant in the disinfectant tank 4 to be sprayed onto the bottom of the car 1. The drying box 31 then transmits warm air to the hot air pipe 32 to dry the damp floor at the bottom of the car 1, preventing passengers from slipping. The long strip channel 33 at the bottom of the car 1 prevents the hot air pipe 32 from dissipating when it blows hot air into the bottom of the car 1. The dustproof net 34 also prevents dust from the elevator shaft from entering the car 1 through the long strip channel 33.

[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
