Technical Field
[0001] This utility model belongs to the technical field of air purification mesh structure for elevator cars, and specifically relates to an air purification mesh structure for elevator cars. Background Technology
[0002] Air purification filters used in elevator cars typically consist of multiple layers of filter material, designed to effectively remove pollutants and particles from the air. Their basic structure includes an outer protective mesh, a middle filter layer, and an inner activated carbon layer. The outer protective mesh primarily prevents the entry of large particles, ensuring the durability and stability of the filtration system. The middle filter layer uses high-efficiency filter materials, such as HEPA filters, to capture fine dust, pollen, and other allergens, ensuring fresh and clean air. The inner activated carbon layer is responsible for adsorbing odors and harmful gases, such as formaldehyde and benzene, further improving air quality. This multi-layered structural design not only improves air purification efficiency but also extends the lifespan of the filter, ensuring that the air inside the elevator car remains fresh and healthy.
[0003] During use, the outermost nylon dustproof net of the air purification net in the elevator car is in direct contact with the external environment, making it the easiest to get dirty. However, in traditional air purification nets, the nylon dustproof net is integrated with the main frame. To clean the nylon dustproof net, the entire main frame needs to be disassembled, which is quite troublesome. Therefore, the market needs a new connection method to solve the current problems. Utility Model Content

However, in traditional air purification meshes, the nylon dustproof mesh is integrated with the main frame, requiring the entire main frame to be disassembled to clean the nylon dustproof mesh, which is inconvenient to use. Therefore, the market needs a new connection method to solve the current problems.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an air purification mesh structure for an elevator car, comprising a main frame and an elevator car body. The upper end of the elevator car body is provided with an air inlet and an air outlet on the left and right sides. The main frame is installed on the inner side of the air inlet and the air outlet. Slots are provided on the left and right sides of the inner wall of the main frame. An inner frame is installed on the main frame through the slots at the inner front end. Adjustment knobs are installed on the front end of the inner frame at the left and right sides.
[0006] The adjustment knob causes the gear shaft fixed at the lower end to rotate. The gear shaft is engaged with the inner side of the inner frame. The gear structure of the gear shaft is engaged with the gear plate sleeved inside the inner frame. A nylon dustproof net installed inside the inner frame performs initial air filtration. A polyester fiber filter layer is provided inside the main frame. A synthetic fiber filter layer for capturing fine particles in the air is provided at the lower end of the polyester fiber filter layer. An activated carbon layer for adsorbing harmful gases in the air is provided at the lower end of the synthetic fiber filter layer.
[0007] Preferably, the main frame is installed on the inner side of the elevator car body, and there are through holes at the four corners of the front end of the main frame. Sound-absorbing foam is provided on the inner wall of the car air inlet and the car air outlet. The shape and structure of the car air inlet and the car air outlet are set as square structures.
[0008] Preferably, the main frame is installed with the elevator car body by inserting bolts into the round holes, and the main frame is installed at the lower end of both the car air inlet and the car air outlet.
[0009] Preferably, the main frame inserts rubber plugs into the inner walls of the car air outlet and the car air inlet, with the rubber plugs tightly attached to the inner walls of the car air outlet and the car air inlet.
[0010] Preferably, a fan is installed at the upper end of the elevator car body, and ventilation ducts are installed at the upper end of the fan on the left and right sides, respectively, and the ventilation ducts are connected to the car air outlet and the car air inlet.
[0011] Preferably, the fan allows air to pass through the main frame and enter the car air inlet via a ventilation duct, and the fan then delivers the purified air back to the interior of the elevator car body through the car air outlet.

[0013] Preferably, the gear structure of the gear shaft is engaged with the gear plate, and the rotation of the gear shaft causes the gear plate to move.
[0014] Preferably, rotation of the gear shaft allows the gear plate to be inserted into the internal position of the slot.
[0015] Compared with the prior art, this utility model provides an air purification mesh structure for elevator cars, which has the following beneficial effects:
[0016] 1. This device has an inner frame installed at the front end of the main frame. The main frame is installed with the inner frame through a slot on the inner wall. The inner frame and the nylon dustproof net are integrated. When installing the inner frame with the main frame, turning the adjustment knob will cause the gear shaft to rotate. Since the gear structure is engaged with the gear plate, the rotation of the gear shaft will cause the gear plate to move. Turning the adjustment knob will rotate the gear plate to the inner position of the inner frame. After the inner frame is installed at the front inner position of the main frame, turning the adjustment knob in the opposite direction will insert the gear plate into the slot, thus completing the installation of the inner frame and the main frame. In this way, when cleaning the nylon dustproof net, only the inner frame needs to be removed. The installation method of the inner frame and the main frame is simple and can be completed quickly during disassembly or installation.
[0017] 2. To prevent unfiltered air leakage, a rubber plug is installed at the upper end of the main frame. When installing the main frame with the car air inlet and outlet, the rubber plug is inserted into the inner wall of the car air inlet and outlet, ensuring that all air passes through the multiple filtration layers inside the air purification mesh before entering the car air inlet. This helps improve the air quality inside the car.
[0018] 3. Sound-absorbing foam is installed on the inner wall of the car air inlet and air outlet of this device. The sound-absorbing foam can absorb sound waves and reduce the noise generated when the air flows, thus providing a quieter operating environment inside the car. Attached Figure Description

Detailed Implementation
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0027] The utility model provides, for example Figure 1-6 The illustrated air purification mesh structure for an elevator car includes a main frame 1 and an elevator car body 13. An air inlet 17 and an air outlet 14 are located on the left and right sides of the upper end of the elevator car body 13. The main frame 1 is installed inside the air inlet 17 and the air outlet 14. Slots 7 are provided on the left and right sides of the inner wall of the main frame 1. An inner frame 5 is installed on the front inner side of the main frame 1 through the slots 7. Adjustment knobs 4 are installed on the left and right sides of the front end of the inner frame 5, allowing it to be fixed at the lower end. The gear shaft 11 rotates and is engaged with the inner side of the inner frame 5. The gear structure of the gear shaft 11 is engaged with the gear plate 8 sleeved inside the inner frame 5. The nylon dustproof net 3 installed inside the inner frame 5 performs initial filtration of the air. A polyester fiber filter layer 6 is provided inside the main frame 1. A synthetic fiber filter layer 12 for capturing fine particles in the air is provided at the lower end of the polyester fiber filter layer 6. An activated carbon layer 10 for adsorbing harmful gases in the air is provided at the lower end of the synthetic fiber filter layer 12.
[0028] The fan 16 is connected to the car air inlet 17 and car air outlet 14 via ventilation ducts 15 on both sides of the upper end, respectively. The car air inlet 17 draws air from inside the car through the air purification net via the fan 16. The air first passes through the nylon dust filter 3, which is the first line of defense in the filtration system. The main function of the nylon dust filter 3 is to block larger particles, such as dust, hair, and insects, to ensure that subsequent filter layers are not contaminated by large particles. After passing through the nylon dust filter 3, the air enters the polyester fiber filter layer 6, which is specifically designed to capture medium-sized particles, such as pollen, etc. Mold spores and fine dust particles are removed, and the air then flows into the synthetic fiber filter layer 12, the third layer of the filtration system, which is specifically designed to capture even smaller particles such as bacteria, viruses, and smoke. Finally, the air, after multiple filtrations, enters the activated carbon layer 10, where activated carbon effectively adsorbs harmful gases, odors, and volatile organic compounds. The purified air is then discharged back into the elevator car through the car's air outlet 14. At this point, the air has undergone multiple filtrations to ensure its cleanliness and safety, effectively improving the air quality inside the elevator car and providing passengers with a healthy and comfortable riding environment.
[0029] like Figure 5 and Figure 6 As shown, the main frame 1 is installed on the inner side of the elevator car body 13. The four corners of the front end of the main frame 1 are provided with through holes 2. Sound-absorbing foam 18 is provided on the inner wall of the car air inlet 17 and the car air outlet 14. The shape and structure of the car air inlet 17 and the car air outlet 14 are set as square structures. The main frame 1 is installed with bolts inserted into the through holes 2 and installed with the elevator car body 13. The main frame 1 is installed at the lower end of the car air inlet 17 and the car air outlet 14. The main frame 1 inserts rubber plugs 9 into the inner wall of the car air outlet 14 and the car air inlet 17. The rubber plugs 9 are tightly attached to the inner wall of the car air outlet 14 and the car air inlet 17.
[0030] When installing the main frame 1 with the car air inlet 17 and the car air outlet 14, insert the rubber plug 9 into the inner wall of the car air inlet 17 and the car air outlet 14. The rubber plug 9 is tightly attached to the inner wall of the car air inlet 17 and the car air outlet 14, thereby ensuring that all air enters the car air inlet 17 after passing through the multiple filter layers inside the air purification net.
[0031] The nylon dust filter 3 effectively captures large particles, protecting the subsequent polyester and synthetic fiber filter layers 12 and extending their service life. The multi-layered structure of the polyester fibers and the electrostatic adsorption between the fibers enable them to effectively remove medium-sized particles from the air, further purifying the air. The design of the synthetic fibers enables them to effectively remove fine particles, ensuring that the air has undergone multiple purification processes before entering the final layer. The activated carbon layer 10 ensures that all residual gaseous pollutants are removed before the air is discharged into the car, providing fresh and healthy air.
[0032] like Figure 2 and Figure 4 As shown, a fan 16 is installed at the upper end of the elevator car body 13. Ventilation ducts 15 are installed on the left and right sides of the upper end of the fan 16. The ventilation ducts 15 are installed with the car air outlet 14 and the car air inlet 17 respectively. The fan 16 allows air to pass through the main frame 1 and enter the car air inlet 17 through the ventilation ducts 15. The fan 16 then delivers the purified air back to the interior of the elevator car body 13 through the car air outlet 14. The adjustment knob 4 is set to a rotary adjustment method. The rotation of the adjustment knob 4 drives the gear shaft 11. The gear structure of the gear shaft 11 engages with the gear plate 8. The rotation of the gear shaft 11 causes the gear plate 8 to move. The rotation of the gear shaft 11 allows the gear plate 8 to be inserted into the interior of the slot 7.
[0033] The main frame 1 is installed with the inner frame 5 through the slot 7 on the inner wall. The inner frame 5 and the nylon dustproof net 3 are integrated. When the inner frame 5 is installed with the main frame 1, the adjustment knob 4 is rotated. The rotation of the adjustment knob 4 drives the gear shaft 11 to rotate. Since the gear structure is engaged with the gear plate 8, the rotation of the gear shaft 11 causes the gear plate 8 to move. Rotating the adjustment knob 4 rotates the gear plate 8 to the inner position of the inner frame 5. After the inner frame 5 is installed at the front inner position of the main frame 1, the adjustment knob 4 is rotated in the opposite direction to insert the gear plate 8 into the inner position of the slot 7, thus completing the installation of the inner frame 5 and the main frame 1. In this way, when cleaning the nylon dustproof net 3, only the inner frame 5 needs to be removed.
[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
