Description

Technical Field

[0001] This utility model relates to the field of automotive parts, specifically a multi-layer composite automotive air conditioning filter. Background Technology

[0002] With the advancement of technology and the improvement of people's living standards, more and more families own their own cars. Cars have many components, and car air conditioning is one of them.

[0003] However, with the increasing severity of air pollution and the growing demand for healthy travel, the performance of car air conditioning filters has become crucial. Currently, most ordinary filters on the market are single-layer non-woven fabric or simple activated carbon layers, which have the following drawbacks:

[0004] 1. Low filtration efficiency: It has limited ability to intercept fine particulate matter such as PM2.5.

[0005] 2. Limited functionality: It can only filter dust, and its adsorption effect on harmful gases such as formaldehyde and TVOC (total volatile organic compounds) and odors is poor or has a short duration.

[0006] 3. Insufficient structural strength: Under the impact of airflow and humidity, the filter media is prone to deformation and collapse, resulting in a decrease in filtration efficiency and a shortened service life.

[0007] 4. Lack of quality: Traditional paper or fiber borders look cheap and do not match the quality feel of high-end cars. Utility Model Content

[0008] To achieve the above objectives, this utility model provides a multi-layer composite automotive air conditioning filter element, which can achieve efficient physical filtration and strong chemical adsorption, is fully functional, has a robust structure, and a long service life, thus solving the aforementioned problems. This utility model provides the following technical solution:

[0009] A multi-layer composite automotive air conditioning filter includes an outer frame and a multi-layer composite filter body disposed within the outer frame. The multi-layer composite filter body includes a meltblown fabric filter layer and a composite adsorption interlayer arranged sequentially along the air intake direction. The composite adsorption interlayer includes a first mesh, a second mesh, and a honeycomb-shaped second support mesh disposed between the first mesh and the second mesh. The pores of the second support mesh are filled with adsorption material. The honeycomb-shaped second support mesh can ensure uniform airflow and provide strong structural support to prevent the composite adsorption interlayer from being crushed.

[0010] As a further embodiment of this utility model, the outer frame is made of plastic.

[0011] As a further embodiment of this utility model: a first supporting mesh is installed on the outside of the composite adsorption interlayer. The first supporting mesh is made of plastic or metal, which can strengthen and fix the structure of the entire product and play a certain decorative role.

[0012] As a further embodiment of this utility model: both the first mesh and the second mesh are made of 304 stainless steel, serving as the upper and lower support surfaces of the composite adsorption interlayer, and possessing good air permeability, corrosion resistance, and extremely high structural strength.

[0013] As a further embodiment of this invention: the adsorption material is a mixture of activated carbon and diatomaceous earth particles, where activated carbon is responsible for adsorbing harmful gases and odors, and diatomaceous earth further regulates humidity and assists in adsorption.

[0014] As a further embodiment of this utility model: the outer frame is integrally formed by injection molding, which tightly covers and fixes the edges of the multi-layer composite filter body to form an integral structure, which not only improves the overall texture and aesthetics of the product, but also ensures the sealing and installation stability of the filter element and the car air conditioning filter box.

[0015] As a further embodiment of this utility model: the outer ring of the outer frame is wrapped with shock-absorbing components, which can buffer the force between the product and the assembly environment during use, and ensure a good and stable assembly and use environment.

[0016] As a further embodiment of this utility model: the shock-absorbing component is made of shock-absorbing sponge, which has good performance and is readily available on the market.

[0017] As a further aspect of this invention: the meltblown fabric filter layer is a PM2.5 high-efficiency meltblown fabric filter layer, which can effectively adsorb and intercept fine particulate matter such as PM2.5.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. High-efficiency multi-stage filtration: Through a multi-stage purification mechanism of "meltblown cloth (physical filtration) + activated carbon / diatom mud (chemical adsorption)," it achieves simultaneous and efficient removal of particulate matter and harmful gases, resulting in comprehensive and significant purification effects.

[0020] 2. Robust and durable structure: The innovative composite sandwich design of "stainless steel mesh + honeycomb support mesh" provides a solid skeleton for loose adsorption particles, which greatly enhances the filter element's resistance to pressure and deformation, and extends its service life, especially in humid environments.

[0021] 3. Uniform airflow distribution: The honeycomb structure allows airflow to pass evenly through the adsorption material, avoiding local airflow short-circuiting and ensuring that all adsorption materials can fully participate in the reaction, thus improving filtration efficiency.

[0022] 4. High-quality appearance: The one-piece molded plastic frame gives the product a premium feel, enhances its grade, and meets the needs of the high-end automotive market.

[0023] 5. Excellent sealing: The robust outer frame ensures the precise matching of the filter element and the mounting groove, effectively preventing unfiltered air from leaking from the edges. Attached Figure Description

The multi-layer composite filter body includes a meltblown fabric filter layer 4 and a composite adsorption interlayer arranged sequentially along the air intake direction. The composite adsorption interlayer includes a first mesh, a second mesh, and a honeycomb-shaped second support mesh 2 disposed between the first mesh and the second mesh. The second support mesh 2 is made of plastic or metal material, and the pores of the second support mesh 2 are filled with adsorption material 3. The honeycomb-shaped second support mesh 2 can ensure uniform airflow and provide strong structural support to prevent the composite adsorption interlayer from being crushed. Combined with the mesh and adsorption material 3, it ensures air permeability and provides firm support for the adsorption material 3. The outer side of the composite adsorption interlayer is installed with a first support mesh 1 made of plastic or metal material, which can strengthen and fix the structure of the entire product and play a certain decorative role. After the meltblown fabric filter layer 4 and the composite adsorption interlayer are pressed together by environmentally friendly adhesive or hot melt method, their edges are covered and sealed by the outer frame 5 in one go to form a sealed and firm whole.

[0029] In one embodiment of this utility model, the outer frame 5 is made of plastic material. Furthermore, the outer frame 5 is injection molded from ABS engineering plastic, which tightly covers and fixes the edges of the multi-layer composite filter body to form an integral structure.

[0031] In one embodiment of this utility model, the adsorbent material 3 is a mixture of activated carbon and diatomaceous earth particles in a weight ratio of 1:1 to 1:2. The activated carbon is responsible for adsorbing harmful gases and odors, while the diatomaceous earth further regulates humidity and assists in adsorption. Moreover, the ratio of activated carbon to diatomaceous earth can be adjusted according to the type of target gas to be purified.

[0032] In one embodiment of this utility model, the outer ring of the outer frame 5 is wrapped with a shock absorber 6, which can buffer the force between the product and the assembly environment during use, and ensure a good and stable assembly and use environment. Furthermore, the shock absorber 6 is made of shock-absorbing sponge, which has good performance and is readily available on the market.

[0033] In one embodiment of this utility model, the meltblown fabric filter layer 4 is a PM2.5 high-efficiency meltblown fabric filter layer with fine fibers, and the filtration efficiency for PM2.5 particles can reach more than 95% (based on specific test standards), which can effectively adsorb and intercept fine particulate matter such as PM2.5.
