Abstract
Description
Technical Field
[0001] This utility model relates to the field of enclosed elevator technology, specifically to an enclosed elevator with an air filtration function. Background Technology
[0002] Existing enclosed elevators typically use a top-intake system, with air exiting through exhaust vents at the bottom of the car or gaps in the side walls, forming a basic air circulation.
[0003] However, this design has the following significant drawbacks:
[0004] 1. Poor air quality: Existing elevators typically only have simple fans and basic dust filters, lacking efficient air purification capabilities. This configuration cannot effectively remove fine particulate matter (such as PM2.5), harmful gases (such as formaldehyde and odors), and microorganisms (such as bacteria and viruses) from the air, resulting in poor air quality inside the elevator car. In particular, the enclosed environment can easily breed odors and spread germs.
[0005] 2. Significant Noise Issues: The fan generates broadband noise during operation, especially rotational and eddy current noise. This noise is directly transmitted into the elevator car, affecting passenger comfort. Current technology lacks effective noise reduction measures, resulting in significant noise levels during elevator operation and a poor user experience.
[0006] 3. Limited functionality: Existing elevator air circulation systems have limited functionality, only providing basic ventilation, which cannot meet the needs of modern buildings for a healthy and comfortable air environment.
[0007] Therefore, we propose a cabin elevator with air filtration function. Utility Model Content

[0029] This embodiment is a cabin elevator with an air filtration function.
[0030] like Figure 1-4 As shown, the elevator includes an elevator car 1. A car top plate 2 is fixedly installed on the top of the elevator car 1. An air intake treatment structure 3 is fixedly installed on the upper outer surface of the car top plate 2. The air intake treatment structure 3 includes a protective cover 8, a base 9, a fan 10, an air intake pipe 11, a stainless steel 304 pre-filter dustproof net 12, an H13 grade HEPA filter element 13, an activated carbon adsorption plate 14, a photohydrogen ion air sterilizer 15, a fixing plate 16, honeycomb holes 17, an exhaust pipe 18, a micro-perforated plate silencer 19, and an air outlet pipe 20. An air inlet 4 is opened in the middle of the upper outer surface of the elevator car 1. An air guide cavity 5 is opened inside the car top plate 2. Inclined exhaust ports 6 are opened on the left and right sides of the lower outer surface of the car top plate 2. A protective net 7 is fixedly installed at the bottom of the inclined exhaust port 6. The lower end of the air inlet 4 is connected to the air guide cavity 5, and the upper end of the inclined exhaust port 6 is connected to the air guide cavity 5.
[0031] The lower end of the exhaust duct 20 is fixed in the air inlet 4. The base 9 is fixed on one side of the middle of the upper outer surface of the top plate 2. The protective cover 8 is fixedly installed on the upper outer surface of the top plate 2. The honeycomb holes 17 are opened on the left outer surface of the protective cover 8. The fan 10 is fixedly installed on the upper outer surface of the base 9. The air inlet duct 11 is fixedly installed on one end of the outer surface of the fan 10. The exhaust duct 18 is fixedly installed between one side of the outer surface of the fan 10 and the upper outer surface of the micro-perforated plate silencer 19. The upper outer surface of the exhaust duct 20 is fixedly connected to the lower end of the micro-perforated plate silencer 19. The stainless steel 304 front dustproof net 12 is fixedly installed on the left end of the inner cavity of the air inlet duct 11. The fixing plate 16 is located on the stainless steel 304 front dustproof net 12. On the right side, the H13 grade HEPA filter 13 is fixed in the middle of the left side of the fixing plate 16, the activated carbon adsorption plate 14 is located on the right side of the fixing plate 16, and the photo-ion air sterilizer 15 is located on the right side of the activated carbon adsorption plate 14.

The photo-ion air sterilizer 15 includes: a dual-band ultraviolet lamp with wavelengths of 185nm + 254nm, an aluminum honeycomb carrier with TiO2 loaded on its surface, and is set at a distance of 10-15cm from the activated carbon adsorption plate 14.

[0032] It should be noted that this utility model is a car-type elevator with air filtration function. The elevator car 1 described in this article belongs to the prior art and can be effectively known to those skilled in the art. Specific details will not be elaborated further. Through the operation of the fan 10, outside air first enters the interior of the protective cover 8 through the honeycomb holes 17. It is then filtered by a stainless steel 304 front dustproof net 12 (made of 304 stainless steel, washable and reusable), an H13 grade HEPA filter 13 (filtering 0.3μm particles), an activated carbon adsorption plate 14 (facilitating the adsorption of odors from the air), and a photo-hydrogen ion air sterilizer 15 (…). It effectively kills harmful microorganisms, such as influenza bacteria and Staphylococcus aureus, and can decompose volatile organic compounds, such as benzene, formaldehyde, ammonia, TVOC and other chemical organic compounds, thereby improving the quality of air treatment. With the installation of micro-perforated plate silencer 19, the perforation rate is 1.2%-1.8%, the plate thickness is 0.5mm, and the hole spacing to hole diameter ratio is ≥3:1. The broadband noise (especially rotation noise and eddy noise) generated by the fan 10 mainly propagates in the direction of air outlet. The rear-mounted micro-perforated plate silencer 19 can effectively attenuate the noise. The treated air is guided by the inclined exhaust port 6 and blown towards the inner wall of the elevator car 1, avoiding direct blowing to the center of the elevator car 1, thus improving comfort.
