Abstract
Description
Technical Field
[0001] This utility model relates to the field of filter technology, and more specifically, to a multi-effect composite antibacterial automotive air conditioning filter. Background Technology
[0002] An automotive air conditioning filter is a specialized filter for purifying the air inside a car cabin. It utilizes a composite filter cloth made of highly efficient adsorption material—activated carbon—and long-filament non-woven fabric. Its compact structure effectively filters smoke, pollen, dust, harmful gases, and various odors. The filter also efficiently filters and adsorbs particulate impurities, achieving oil filtration and air purification performance, while effectively removing TVOCs, benzene, phenols, ammonia, formaldehyde, xylene, styrene, and other organic gases.
[0003] For example, the multi-effect composite automotive air conditioning filter element with public announcement number CN207203666U includes HEPA filter paper and PP environmentally friendly honeycomb mesh. The front and back of the HEPA filter paper are reinforced with adhesive strips. The PP environmentally friendly honeycomb mesh is composed of several mesh holes. Both sides of the PP environmentally friendly honeycomb mesh are covered with a mesh, and the mesh holes are mainly filled with nano-mineral crystals. Both the HEPA filter paper and the PP environmentally friendly honeycomb mesh are edged with cardboard, and a layer of sponge is also provided on the edge of the cardboard. The HEPA filter paper adopts a rectangular grid combination structure. This new type adopts a multi-effect composite honeycomb structure. A blue antibacterial layer is laminated on the HEPA filter paper. It is made of the same material as the blue masks worn by doctors. This air conditioning filter element has a good filtering and absorption effect on harmful substances such as PM2.5, smog, car odors, and formaldehyde in current polluted weather.
[0004] However, based on the working principle proposed in the aforementioned patent, the applicant believes that although the aforementioned device can improve the filtration effect of harmful substances to a certain extent, in actual use, the device's fine filtration capability is relatively weak, and there are certain defects in its use. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a multi-effect composite antibacterial automotive air conditioning filter element, which has the advantage of stronger fine filtration capability.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-effect composite antibacterial automotive air conditioning filter element, comprising an outer protective layer, an antibacterial layer disposed on the inner side of the outer protective layer, a high-efficiency particulate filter layer disposed on the inner side of the antibacterial layer, an activated carbon adsorption layer disposed on the inner side of the high-efficiency particulate filter layer, and an inner protective layer disposed on the inner side of the activated carbon adsorption layer.
[0007] As a preferred technical solution of this utility model, the outer protective layer is made of tough and breathable non-woven fabric material, which is relatively thick and flat, with a slight texture on the surface.
[0008] As a preferred technical solution of this utility model, the antibacterial layer is made of non-woven fabric containing antibacterial components such as silver ions and zinc ions, and the whole presents a fine fiber network or a uniformly distributed coating.
[0009] As a preferred technical solution of this utility model, the high-efficiency particulate filter layer is made of electret meltblown nonwoven fabric, with an overall fiber diameter of extremely fine, presenting a complex three-dimensional mesh structure.
[0010] As a preferred embodiment of this invention, the activated carbon adsorption layer is made of granular activated carbon, and its overall morphology is a loosely but tightly arranged granular layer.
[0011] As a preferred technical solution of this utility model, the inner protective layer is made of fiber material, with a relatively smooth overall shape and a material similar to that of the outer protective layer. The upper and lower sides of the inner protective layer are fixedly installed with outer limiting plates.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] This utility model integrates multiple layers, from the outer protective layer to the inner protective layer, each optimized for specific functions, collectively forming a highly efficient, durable, and intelligent filtration system. The outer protective layer uses a tough and breathable non-woven fabric material, serving as the first line of defense to block large particles and provide physical support. Next is an antibacterial layer containing antibacterial components such as silver ions and zinc ions, or photocatalyst materials, which effectively inhibits the growth of bacteria, viruses, and other microorganisms, ensuring clean air inside the vehicle. The high-efficiency particulate filter layer efficiently captures PM2.5-level fine particles, ensuring the air entering the cabin is as pure as possible. The activated carbon adsorption layer uses granular activated carbon to powerfully adsorb harmful gases and odors, further improving air quality. The inner protective layer complements the outer protective layer, preventing internal materials from falling off and ensuring smooth airflow distribution. This multi-layered composite structure not only improves overall filtration efficiency but also enhances antibacterial and deodorizing functions, providing stronger fine filtration capabilities and offering users a healthier and more comfortable riding environment.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] like Figures 1 to 3 As shown, this utility model provides a multi-effect composite antibacterial automotive air conditioning filter element, including an outer protective layer 1, an antibacterial layer 2 disposed on the inner side of the outer protective layer 1, a high-efficiency particulate filter layer 3 disposed on the inner side of the antibacterial layer 2, an activated carbon adsorption layer 4 disposed on the inner side of the high-efficiency particulate filter layer 3, and an inner protective layer 5 disposed on the inner side of the activated carbon adsorption layer 4.
[0020] The outer protective layer 1 is made of a tough and breathable non-woven fabric material, which is relatively thick and flat with a slight texture on the surface.
[0021] The outer protective layer 1 serves as the first line of defense, blocking large particles such as dust and leaves from entering the filter element. It also provides physical support to prevent damage to the filter element during installation or disassembly.
[0022] The antibacterial layer 2 is made of non-woven fabric containing antibacterial components such as silver ions and zinc ions, and presents an overall fine fiber network or a uniformly distributed coating.
[0023] The antibacterial layer 2 is designed to inhibit or kill microorganisms such as bacteria, viruses, and fungi, thereby reducing the risk of these pathogens spreading inside the vehicle and maintaining the cleanliness of the air inside the vehicle.
[0024] Among them, the high-efficiency particulate filter layer 3 is made of electret meltblown nonwoven fabric, with extremely fine fiber diameter, presenting a complex three-dimensional mesh structure.
[0025] With the addition of a high-efficiency particulate filter layer 3, it can effectively capture fine particulate matter at the PM2.5 level, and can even achieve a filtration efficiency of over 99.97% for particles larger than 0.3 micrometers, ensuring that the air entering the vehicle is as pure as possible.
[0026] Among them, the activated carbon adsorption layer 4 is made of granular activated carbon, and its overall shape is a loose but tightly arranged granular layer.
[0027] By setting up the activated carbon adsorption layer 4, odors and harmful gases (such as formaldehyde, benzene and other volatile organic compounds VOCs) in the air can be adsorbed, as well as some smaller water-soluble pollutants, improving the air quality inside the vehicle and reducing odors.
[0028] The inner protective layer 5 is made of fiber material and has a relatively smooth overall shape. Its material is similar to that of the outer protective layer 1. The upper and lower sides of the inner protective layer 5 are fixedly installed with outer limiting plates 6.
[0029] The inner protective layer 5 provides additional structural support for the entire filter element and prevents internal materials from falling off or shifting, ensuring smooth airflow through each layer without short-circuiting.
[0030] The working principle and usage process of this utility model: In this device, multiple layers are integrated, from the outer protective layer 1 to the inner protective layer 5. Each layer is optimized for a specific function, together forming a highly efficient, durable, and intelligent filtration system. The outer protective layer 1 uses a tough and breathable non-woven fabric material, which serves as the first line of defense to block large particles and provide physical support. Next is the antibacterial layer 2, which contains antibacterial components such as silver ions and zinc ions or photocatalyst materials, which can effectively inhibit the growth of bacteria, viruses, and other microorganisms, ensuring the hygiene of the air inside the vehicle. The high-efficiency particulate filter layer 3 can efficiently capture fine particulate matter at the PM2.5 level, ensuring that the air entering the vehicle is as pure as possible. The activated carbon adsorption layer 4 can strongly adsorb harmful gases and odors through granular activated carbon, further improving air quality. The inner protective layer 5 echoes the outer protective layer 1, preventing internal materials from falling off and ensuring smooth airflow distribution. This multi-layer composite structure not only improves the overall filtration efficiency but also enhances antibacterial and deodorizing functions, resulting in stronger fine filtration capabilities.
