Description

Technical Field

[0001] This utility model belongs to the field of air purifier technology, specifically relating to a novel solar-powered vehicle-mounted photocatalytic air purifier. Background Technology

[0002] Harmful gases from various car parts and materials have a long release period. Plastic parts, carpets, headliners, and sofas installed in the car, if not installed according to strict environmental protection requirements, will directly cause air pollution inside the vehicle. Currently, formaldehyde can be used in various stages of leather manufacturing, but most formaldehyde in leather is produced during tanning and retanning. Various solvent-based adhesives are used in car interiors, such as wallpaper adhesives, carpet adhesives, sealant adhesives, and plastic adhesives. These adhesives release formaldehyde, benzene, toluene, xylene, and other volatile organic compounds during use. Most consumers will redecorate their car interiors after purchase, and some cars need redecorating after a period of use. Some dealers also offer free accessories with car purchases as a promotional offer. Some floor mats, seat covers, and adhesives containing harmful substances enter the car interior. The toxic gases contained in these decorative materials, mainly including benzene, formaldehyde, acetone, and xylene, will inevitably cause air pollution inside the vehicle. If a car's air conditioning evaporator is not cleaned and maintained for a long time, a large amount of dirt will accumulate inside. The resulting harmful substances such as amines, nicotine, and bacteria will permeate the confined space of the car, leading to poor air quality and even oxygen deficiency. Furthermore, due to the small space inside a car, the good sealing of new cars, and poor air circulation, the amount of air inside is already limited. Combined with severe cross-contamination among passengers, the excessive levels of harmful gases in a car are more harmful to human health than excessive levels of harmful gases indoors. When the carbon dioxide concentration in the air reaches 0.5%, people will experience headaches, dizziness, and other discomfort. If the driver or passengers smoke, it will not only greatly increase the levels of air pollutants such as volatile organic compounds, carbon monoxide, and dust, but the emitted odors may also linger in the car for a long time.

[0003] Most photocatalytic air purifiers today require optimal indoor lighting conditions and a period of ultraviolet (UV) irradiation to achieve significant sterilization. TiO2 is currently the most representative photocatalytic material, but it doesn't effectively utilize UV ​​light response and cannot maximize solar energy utilization. Even with doping to improve photosensitivity, its efficiency remains relatively low. Among various semiconductor photocatalysts, ZnO offers advantages such as low cost, non-toxicity, high quantum efficiency, and environmental friendliness, making it a current research hotspot. A novel photocatalytic material, Fe3O4 / ZnO / g-C3N4 nanocomposite material, is used. Currently, many car air purifiers use activated carbon filters, as activated carbon adsorbs formaldehyde. However, activated carbon cannot actively adsorb formaldehyde. It "absorbs" formaldehyde, but when formaldehyde-containing air passes through the micropores of activated carbon, formaldehyde molecules are trapped. Therefore, most air purifiers or fresh air systems that remove formaldehyde use activated carbon. Activated carbon has adsorption saturation. Compared to formaldehyde released indoors over a long period, ordinary activated carbon has a very small adsorption capacity and its direct placement will pollute the environment, making its use and removal value low. Although effective, it requires frequent replacement. However, photocatalytic filters remove organic pollutants because the catalyst they contain reacts with oxygen and water under light stimulation to generate negative ions and hydroxyl radicals. These substances can oxidize and decompose pollutants such as formaldehyde, ultimately producing harmless substances such as carbon dioxide, water, and corresponding acids, thereby purifying the air. During the photocatalytic process, the filter itself does not change or suffer loss; it only provides a reaction site. It has the advantages of long-lasting effect, continuous action, stable properties, and safety and non-toxicity. Theoretically, its effective period is very long, maintenance costs are low, and it does not produce secondary pollution. The photocatalyst material of this product is a magnetically separable Fe3O4 / ZnO / g-C3N4 nanocomposite material, which has demonstrated excellent photocatalytic performance through experimental testing. Utility Model Content

[0004] This invention provides a novel solar-powered vehicle-mounted photocatalytic air purifier, which aims to purify the air inside the vehicle and reduce air pollution.

[0005] Therefore, the present invention adopts the following technical solution:

[0006] A new type of solar-powered vehicle photocatalytic air purifier includes, from top to bottom, a purifier cover, a purifier body, and a purifier base connected in sequence.

[0007] A solar panel is fixed to the top of the air purifier cover. A crescent-shaped air inlet is opened on the edge of the air purifier cover. The air inlet passes through the air purifier cover and the air purifier cover is detachably connected to the air purifier body.

[0008] The air purifier body has a hollow center, inside which multiple filter elements can be detachably installed. The multiple filter elements are stacked, and the air drawn in through the air inlet is filtered through the multiple filter elements in sequence. The air purifier body is equipped with an ultraviolet lamp ring along the edge of the cavity.

[0009] The purifier base has a disc-shaped structure and is fixed below the purifier body. A fan is fixed in the center of the purifier base, and multiple air outlets are provided along the outer edge of the purifier base. The air that has passed through the filter element is discharged from the air outlets after passing through the fan. The purifier base also contains a battery and a negative ion generator. The battery and solar panel are electrically connected. The solar panel powers the battery, and the battery powers the fan and ultraviolet lamp.

[0010] Furthermore, the filter element comprises two stages: an upper stage consisting of a high-efficiency nano-bacterial coating plate and a photocatalytic honeycomb mesh, and a lower stage consisting of a HEPA high-efficiency filter mesh. The two stages of the filter element are supported and fixed by a fixing ring.

[0011] Furthermore, it also includes a control system circuit board located inside the purifier base, and a display screen, speed adjustment touch key, and power switch touch key are provided on the outer edge of the purifier body, which are electrically connected to the control system circuit board.

[0012] Furthermore, the purifier base is also equipped with a USB power port, which is used to power the battery.

[0013] Furthermore, the outer contours of the purifier's top cover, body, and base are all circular.

[0014] Furthermore, the purifier cover and the purifier body are tightly connected by a magnetic adsorption socket structure.

[0015] Furthermore, the solar panel extends two wires that contact the spring probe of the purifier body to achieve circuit connection.

[0016] Furthermore, the purifier body is also provided with a bypass hole on its edge. Part of the air entering through the air inlet enters the fan after passing through the bypass hole. The bypass hole forms an air bypass channel, which aims to reduce the resistance of the fan operation and improve the air circulation inside the vehicle.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. Adopting a dual power supply design of solar panel and vehicle power supply, this in-vehicle air purifier uses multiple composite purification technologies such as HEPA high-efficiency filter, high-efficiency nano-sterilization coating, photocatalytic catalyst, UV-C (ultraviolet sterilization and disinfection) and negative ions to purify the air in the car. It can effectively remove organic pollutants such as formaldehyde, VOCs (volatile organic compounds), benzene, and xylene, and can sterilize and eliminate viruses. Each filter can target pollutants in the air, comprehensively sweeping away chemical gases, fine particles, viruses and bacteria;

[0019] 2. The system features three speed settings customized to sleep standards and a display on the purifier showing real-time air quality inside the vehicle, creating a comprehensively healthy and comfortable breathing space. Air enters through an ion generator, increasing negative ions, and is then exhausted through the vents. This simple and practical device starts automatically with the vehicle and continues purifying for one hour after being turned off, effectively improving in-car air quality and is easy to implement.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0029] like Figure 1 , 2 The diagram shows the external appearance and working schematic of the new solar-powered vehicle-mounted photocatalytic air purifier. The components of the new solar-powered vehicle-mounted photocatalytic air purifier are as follows:

[0030] 1. Dual Power Supply Design for the Air Purifier: The air purifier offers two power supply options: solar power and vehicle-mounted power. It consists of a solar panel 1, a battery 11, and a USB power port 12. Users can activate the power supply, fan 15, and UV lamp ring 7 by touching the power switch 10. The fan 15 can be controlled at three speeds via the speed control touch button 8. This dual power supply design eliminates concerns about the air purifier running out of power or being forgotten to be plugged in.

[0031] 2. Ultraviolet lamp ring 7: such as Figure 1 As shown, the ultraviolet lamp ring 7 is placed near the filter element. Ultraviolet light irradiates the photocatalytic honeycomb mesh and excites the photocatalyst.

[0032] 3. Filter Cartridge: The filter cartridge mainly consists of a high-efficiency nano-sterilizing coating plate, a photocatalytic honeycomb mesh 3, a HEPA high-efficiency filter 4, and a fixing ring 5. After being irradiated by ultraviolet light, the air reaches the first high-efficiency nano-sterilizing coating plate. This filter layer is rich in high-quality antibacterial ions, initially filtering hair, dust, pollen, secondhand smoke, etc., effectively removing allergens and bacteria with a removal rate of up to 99%. The initially filtered air then passes through the second photocatalytic honeycomb mesh, which adsorbs and decomposes harmful gases such as formaldehyde, benzene, and TVOCs, before entering the HEPA high-efficiency filter 4, which filters fine particulate matter such as PM2.5. These three layers of filters with different functions effectively filter the air inside the car, removing harmful gases and providing a fresh and healthy air environment for the occupants.

[0033] 4. Negative ion generator 14: Negative ion generator 14 as... Figure 6 In this system, negative ions generate active oxygen, effectively activating oxygen molecules in the air, making them more active and easier for the body to absorb, effectively preventing "air conditioning sickness"; improving lung function; promoting metabolism; enhancing disease resistance; improving sleep; sterilizing; removing dust and bacteria, and more effectively reducing the harm of secondhand smoke; freshening the air and eliminating smoke and dust: negatively charged ions neutralize positively charged smoke and dust floating in the air through electrode neutralization, causing them to settle naturally. The negative ion generator 14 makes the filtered air more beneficial, providing more health benefits to the people inside the vehicle.

[0034] 5. Control and Detection System: This mainly consists of a display screen 9 and a control system circuit board 16. The control system circuit board 16 is installed below the display screen 9, near the air outlet 13. After the air is fully filtered, it passes through the control system circuit board 16, where the detection system detects the formaldehyde content in the filtered air, and the content is displayed on the display screen 9.

[0035] Laboratory studies have shown that the photocatalytic materials used are non-toxic, harmless to the human body, safe, reliable, and do not produce secondary pollution. They also have exceptionally low operating costs and can operate continuously for extended periods. The use of a magnetic zinc oxide / carbon nanotube composite material with excellent adsorption and photocatalytic properties, combined with ultraviolet light, ensures effective sterilization and disinfection. An added negative ion generator (14) releases negative ions into the purified air, further optimizing air quality. The filter is replaceable; only the HEPA high-efficiency filter (4) needs replacement approximately once a year, and the entire filter can be replaced after about two years. Replacement is based on the lifespan of each filter element, saving materials, reducing costs, maximizing the performance of the photocatalytic materials, and making replacement convenient and easy to implement.
