Description

Technical Field

[0001] This utility model relates to a disinfection device, and more particularly to a disinfection device for elevator cars used in the field of elevators. Background Technology

[0002] Because elevators are enclosed spaces with poor air circulation, and have a large flow of people and frequent close contact, they can produce a mixture of odors that can cause strong discomfort. At the same time, people breathing, talking, coughing, and sneezing in the elevator can spread droplets, which can easily cause cross-infection in groups.

[0003] To address the aforementioned issues, a search revealed, for example, a disinfection device for elevator cars disclosed in patent publication number CN220967759U. This device includes a coil and two fixed plates fixedly connected to the inner walls on both sides of the car body. Multiple atomizing nozzles are fixedly connected to the bottom of the coil. A disinfectant tank is fixedly connected to the top of one of the fixed plates, and a water pump is fixedly connected to one side of the disinfectant tank. A bracket is fixedly connected to the top inner wall of the car body, and a connecting pipe is fixedly connected inside the bracket, with the connecting pipe connected to the water pump. The device's design, utilizing a bidirectional threaded rod, a fixing block, and a baffle, prevents collisions with the atomizing nozzles, improving the device's protective effect. Furthermore, the pushing mechanism allows the mist sprayed from the atomizing nozzles to diffuse to all corners of the car body, improving the device's usability. Additionally, the filter screen purifies the air entering the car body, enhancing the device's filtration efficiency.

[0004] Based on the above search and combined with the existing technology, it was found that the existing elevator car disinfection devices disclosed above can only disinfect the car when no one is in it, and cannot disinfect the car when someone is in it. Therefore, an elevator car disinfection device is proposed to improve the above problems. Utility Model Content

[0005] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is that the disinfection devices for elevator cars disclosed above can only disinfect the car when no one is in it, and cannot disinfect the car when someone is in it.

[0006] To solve the above problems, this utility model provides a disinfection device for elevator cars, including a first disinfection device and a second disinfection device installed on two opposite vertical sides of the car body, and both the first disinfection device and the second disinfection device are connected to the interior of the car body, and air ducts are installed at both ends of the upper end of the car body.

[0007] One end of an air duct located on the upper side of the car body is set with its opening facing upwards, and the other end of the duct is fixedly connected to the second disinfection device.

[0008] One end of an air duct located on the lower side of the car body is set downwards, and the other end is fixedly connected to the second disinfection device.

[0009] A one-way ventilation structure is installed at the duct opening that is far from the second disinfection device;

[0010] A reinforcing structure is installed between the air duct and the elevator shaft to increase the ventilation volume inside the air duct per unit time.

[0011] In the aforementioned elevator car disinfection device, by installing air ducts on both the upper and lower sides of the car body, the air outside the car body can be injected into the second disinfection device for disinfection during the car body's up and down movement. Then, the air is introduced into the car body, carrying the air inside the car body into the first disinfection device for disinfection before being discharged to the outside of the car body. This cycle is repeated to achieve disinfection of the air inside the car body.

[0012] As a further improvement to this application, an air duct is fixed to the end of the air duct away from the second disinfection device, and a filter screen is installed on the air duct.

[0013] As a further improvement of this application, mesh panels are installed inside both sides of the car body near the first and second disinfection devices, with gaps between the mesh panels and the inner walls of the car body.

[0014] As a further improvement of this application, multiple support columns are fixed between the mesh panel and the inner wall of the car body.

[0015] As a further improvement of this application, the one-way ventilation structure includes a switch plate and a baffle plate. One end of the switch plate is installed at the duct opening via a torsion spring, and the baffle plate is fixed to the inner wall of the duct on the side of the switch plate away from the torsion spring.

[0016] As a further improvement to this application, the reinforcing structure includes a wheel blade, a transmission gear, and a transmission rack;

[0017] An integrated expansion pipe is fixedly connected to the air duct. The impeller is rotatably installed on the inside of the expansion pipe. A transmission gear is located on the outside of the expansion pipe and is fixed coaxially with the impeller. The transmission rack is fixed on the elevator shaft, and the transmission gear meshes with the transmission rack.

[0018] As a further improvement to this application, the reinforcing structure includes a wheel blade, a first transmission gear, a transmission rack, a second transmission gear, and a third transmission gear.

[0019] An integrated expansion pipe is fixedly connected to the air duct. The impeller is rotatably installed on the inner side of the expansion pipe. The first transmission gear is located on the outer side of the expansion pipe and is fixed coaxially with the impeller. The transmission rack is fixed on the elevator shaft. The second transmission gear is rotatably installed on the side end of the expansion pipe and meshes with the first transmission gear. The third transmission gear is coaxially fixed with the second transmission gear and meshes with the transmission rack. The diameter of the second transmission gear is larger than the diameters of the first and third transmission gears.

[0020] In summary, during the elevator car's ascent and descent, air from the outside of the car body can be injected into the second disinfection device through the duct for disinfection, then introduced into the car body, carrying the air from the car body into the first disinfection device for disinfection before being discharged back to the outside of the car body. This cycle is repeated to disinfect the air inside the car body. Furthermore, the reinforcing structure between the duct and the elevator shaft can accelerate the speed at which airflow enters the inside of the duct, thereby increasing the ventilation volume inside the duct per unit time and enhancing the disinfection effect.

[0028] The three embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0029] Implementation method 1:

[0030] Figures 1-3The diagram shows a disinfection device for an elevator car, comprising a first disinfection device 2 and a second disinfection device 3 installed on two opposite vertical sides of the car body 1. Both the first disinfection device 2 and the second disinfection device 3 can be existing conventional air disinfection devices, such as air disinfection devices with built-in conventional HEPA filter layers and porous high-iodine-value activated carbon, and both the first disinfection device 2 and the second disinfection device 3 are connected to the interior of the car body 1.

[0031] Air ducts 4 are installed at both ends of the upper part of the car body 1. One end of the air duct 4 located on the upper side of the car body 1 is set with its opening facing upward, and the other end is fixedly connected to the second disinfection device 3. One end of the air duct 4 located on the lower side of the car body 1 is set with its opening facing downward, and the other end is fixedly connected to the second disinfection device 3. A one-way ventilation structure is installed at the opening of the air duct 4 away from the second disinfection device 3. Specifically, the one-way ventilation structure includes a switch plate 15 and a baffle plate 16. One end of the switch plate 15 is installed at the opening of the air duct 4 through a torsion spring, and the baffle plate 16 is fixed to the inner wall of the air duct 4 on the side of the switch plate 15 away from the torsion spring.

[0032] The elevator car disinfection device uses air ducts 4 installed on both the upper and lower sides of the car body 1. During the up and down movement of the car body 1, the air outside the car body 1 is injected into the second disinfection device 3 through the air ducts 4 for disinfection. Then, it is introduced into the car body 1, and together with the air in the car body 1, it is introduced into the first disinfection device 2 for disinfection before being discharged to the outside of the car body 1. This cycle is repeated to disinfect the air inside the car body 1.

[0033] As a further improvement of this application, an air duct 7 is fixed to the end of the air duct 4 away from the second disinfection device 3, and a filter screen 8 is installed on the air duct 7.

[0034] In addition, mesh panels 5 are installed on both sides of the car body 1 near the first disinfection device 2 and the second disinfection device 3. There is a gap between the mesh panels 5 and the inner wall of the car body 1, which can increase the air intake and exhaust area and prevent the disinfection process from being affected by partial obstruction.

[0035] Among them, multiple support columns 6 are fixed between the mesh plate 5 and the inner wall of the car body 1, which can support the mesh plate 5 and make the mesh plate 5 less susceptible to deformation by external forces.

[0036] The second implementation method:

[0037] A reinforcing structure is installed between the air duct 4 and the elevator shaft to increase the ventilation volume of the inner side of the air duct 4 per unit time.

[0038] Regarding the reinforcement structure, specifically, such as Figure 4As shown, the reinforcing structure includes a blade 10, a transmission gear 11, and a transmission rack 12. An expansion pipe 9 is integrally fixed and connected to the air duct 4. The blade 10 is rotatably mounted on the inner side of the expansion pipe 9. The transmission gear 11 is located on the outer side of the expansion pipe 9 and is coaxially fixed with the blade 10. The transmission rack 12 is fixed on the elevator shaft, and the transmission gear 11 meshes with the transmission rack 12.

[0039] It should be further explained that the two reinforcing transmission racks 12 are staggered, that is, one transmission gear 11 corresponds to one transmission rack 12.

[0040] When the car body 1 moves upward, the wheel blade 10 located on the upper side of the car body 1 rotates under the meshing action of the transmission gear 11 and the transmission rack 12, thereby accelerating the speed at which the airflow enters the inside of the air duct 4, thus increasing the ventilation volume inside the air duct 4 per unit time and achieving a better disinfection effect; similarly, when the car body 1 moves downward, the wheel blade 10 located on the lower side of the car body 1 rotates under the meshing action of the transmission gear 11 and the transmission rack 12, thereby also accelerating the speed at which the airflow enters the corresponding air duct 4.

[0041] The third implementation method:

[0042] A reinforcing structure is installed between the air duct 4 and the elevator shaft to increase the ventilation volume of the inner side of the air duct 4 per unit time.

[0043] Regarding the reinforcement structure, specifically, such as Figure 5 As shown, the reinforcing structure includes a blade 10, a first transmission gear 11, a transmission rack 12, a second transmission gear 13, and a third transmission gear 14. An expanded diameter pipe 9 is integrally and fixedly connected to the duct 4. The blade 10 is rotatably mounted on the inner side of the expanded diameter pipe 9. The first transmission gear 11 is located on the outer side of the expanded diameter pipe 9 and is coaxially fixed with the blade 10. The transmission rack 12 is fixed to the elevator shaft. The second transmission gear 13 is rotatably mounted on the side end of the expanded diameter pipe 9 and meshes with the first transmission gear 11. The third transmission gear 14... The second drive gear 13 is fixed coaxially, and the third transmission gear 14 meshes with the transmission rack 12. Since the diameter of the second transmission gear 13 is larger than the diameters of the first transmission gear 11 and the third transmission gear 14, when the car body 1 moves vertically for the same distance, the first transmission gear 11 in this embodiment rotates more times than the first transmission gear 11 in the second embodiment. That is, the wheel blade 10 rotates faster in this embodiment. Correspondingly, the ventilation volume inside the air duct 4 per unit time is also greater, and the disinfection effect is stronger.

[0044] Similarly, it should be further explained that the two reinforcing transmission racks 12 are staggered, that is, one transmission gear 14 corresponds to one transmission rack 12.

[0045] Taking the upward movement of the car body 1 as an example, when the car body 1 moves upward, the wheel blade 10 located on the upper side of the car body 1 rotates under the meshing action of the transmission gear 11, transmission gear 2 13, transmission gear 3 14 and transmission rack 12, thereby accelerating the speed at which the airflow enters the inside of the air duct 4, thereby increasing the ventilation volume inside the air duct 4 per unit time and enhancing the disinfection effect.

[0046] Compared to the disinfection method of simply spraying disinfectant, this solution can disinfect the air inside the car body 1 in real time when people are present, without the need for any electrical equipment, making the disinfection operation more energy-efficient and reliable.

[0047] Of course, in order to ensure the cleanliness of the interior of the car body 1, a conventional disinfectant spraying device (not shown in the figure) can be installed in the car body 1 to regularly spray disinfectant inside the car body 1.

[0048] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
