Description

Technical Field

[0001] This utility model relates to the field of vehicle filter technology, and more specifically, to a vehicle filter with an activated carbon layer. Background Technology

[0002] Vehicle filters are important components in car engine intake systems, air conditioning systems, and other systems used to filter impurities. They are mainly composed of filter paper and a plastic frame. In the engine intake system, the air filter filters the air entering the engine, preventing dust, sand, and other impurities from entering, ensuring normal engine operation, reducing wear, and improving fuel efficiency. In the air conditioning system, the cabin air filter filters dust, pollen, odors, etc., from the recirculated air inside the vehicle or the fresh air entering from outside, providing a clean and comfortable air environment for passengers, protecting their health and ride comfort. Vehicle filters may vary in size, shape, and filtration precision depending on the vehicle model, requiring selection and replacement based on the specific vehicle type.

[0003] However, existing vehicle filters typically use a combination of non-woven fabric and activated carbon layers. The non-woven fabric can intercept larger particles, while the activated carbon layer adsorbs odors and harmful gases. However, this single combination is insufficient for effectively adsorbing moisture and reducing internal humidity during filtration. When humid air enters the filter, water vapor is directly adsorbed inside. Due to the multi-layered structure, airflow is poor, and moisture cannot evaporate quickly. Over time, accumulated moisture not only breeds bacteria and mold, emitting unpleasant odors, but can also cause discomfort to the driver and passengers due to continuously increasing humidity inside the cabin. Furthermore, when the air conditioning is on, some microorganisms can easily spread into the vehicle's interior, producing odors and reducing passenger comfort. Long-term exposure may also affect the health of passengers, causing numerous problems for vehicle use. While activated carbon alone can adsorb odors, it is still insufficient to deal with some viruses and bacteria, undoubtedly causing significant inconvenience in practical use. Therefore, we propose a vehicle filter with an activated carbon layer. Summary of the Invention

[0004] Technical problems to be solved The purpose of this invention is to provide a vehicle filter element with an activated carbon layer to solve the problems mentioned in the background art.

[0005] Technical solution A vehicle filter element with an activated carbon layer includes a frame one, a pre-filter layer adhered to the inner wall of the frame one, a frame two fixedly connected to the outer wall of the frame one, an activated carbon filter layer adhered and fixed to the inner wall of the frame two, and a HEPA filter layer, an antibacterial and antiviral layer and a moisture-absorbing filter plate snapped into the inside of the frame two.

[0006] Preferably, the plurality of ventilation openings are circular and through-type, and the plurality of ventilation openings are distributed in a linear array on the outer walls of the frame.

[0007] Preferably, threaded grooves are provided on the outer walls of both sides of the frame, and ventilation openings are provided on the outer walls of all four sides of the frame.

[0008] Preferably, the outer wall of the second frame is provided with screw holes, and screws are fitted into the inner walls of the screw holes, with the screws fixedly connected to the corresponding threaded grooves.

[0009] Preferably, the HEPA filter layer and the antibacterial and antiviral layer are sewn together, and the HEPA filter layer is disposed on the outer wall behind the antibacterial and antiviral layer.

[0010] Preferably, a moisture-absorbing cylinder is adhered to the outer wall of the moisture-absorbing filter plate, and multiple moisture-absorbing cylinders are distributed in a rectangular array on one side of the outer wall of the moisture-absorbing filter plate.

[0011] Beneficial effects Compared with the prior art, the advantages of this utility model are as follows: In actual use, a moisture-absorbing filter plate is set behind the primary filter layer of the filter element. The moisture-absorbing filter plate can absorb moisture from the intake air. The outer wall of the moisture-absorbing filter plate is equipped with moisture-absorbing cylinders. Since multiple moisture-absorbing cylinders have a certain length, they will fit against the outer wall of the primary filter layer after installation, thus forming an air-circulating area between the moisture-absorbing filter plate and the primary filter layer. After the intake airflow is filtered by the primary filter layer, it can absorb some moisture through the moisture-absorbing filter plate and multiple moisture-absorbing cylinders, reducing the situation where moisture directly enters the cab and causes the humidity to rise continuously, causing discomfort to the driver. Furthermore, the moisture-absorbing filter plate and the moisture-absorbing cylinders on the outer wall can work together with multiple vents and the diameter of the primary filter layer itself in the air-circulating area to evaporate moisture to the outside through the gaps when the air conditioning is not used, thereby avoiding the situation where moisture is difficult to evaporate due to the stacking of multiple filter elements. Furthermore, after moisture adsorption, the device passes through an antibacterial and antiviral layer and a HEPA filter layer. The antibacterial and antiviral layer can inhibit and kill bacteria, viruses, and other microorganisms in the air, preventing them from growing and multiplying on the filter element. Combined with the reduction of humidity, it can better reduce bacterial growth and avoid secondary pollution, protecting the health of people in the vehicle. The HEPA filter layer has a high filtration efficiency for bacteria such as E. coli and Staphylococcus aureus, effectively intercepting bacterial carriers and reducing the spread of bacteria in the air. For viruses such as influenza viruses, although the virus itself is small in size, they usually attach to droplet nuclei or other particulate matter. The HEPA filter layer can reduce the concentration of viruses in the air by filtering these carriers, reducing the risk of infection. This, in turn, better works with the pre-filter and activated carbon filter layer to ensure the air filtration effect. Attached Figure Description

[0014] In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] Please see Figure 1-4 This utility model provides a technical solution: A vehicle filter element with an activated carbon layer includes a frame 100, a pre-filter layer 110 adhered to the inner wall of the frame 100, a frame 200 fixedly connected to the outer wall of the frame 100, an activated carbon filter layer 220 adhered and fixed to the inner wall of the frame 200, and a HEPA filter layer 230, an antibacterial and antiviral layer 240 and a moisture-absorbing filter plate 140 snapped into the inside of the frame 200.

[0017] In some embodiments: the primary filter layer 110 is a folded non-woven fabric, and the HEPA filter layer 230 is formed by adding negative ion powder to the filter material of the filter element, or by coating it onto the surface of the filter element to improve the filter element's ability to release negative ions. The HEPA filter layer is made of synthetic fibers, such as polyester fibers and polypropylene fibers. The synthetic fiber filter layer has good flexibility and strength and is not easily damaged. At the same time, through spinning and processing, the fibers can have suitable pore size and surface characteristics to achieve high-efficiency filtration. The antibacterial and antiviral layer 240 can use fiber materials containing antibacterial agents (such as silver ions, quaternary ammonium salts, etc.) or nanomaterial coatings with antiviral functions, such as titanium dioxide nanocoatings, which can inhibit and kill bacteria, viruses and other microorganisms in the air, prevent them from growing and multiplying on the filter element, avoid secondary pollution, and protect the health of the people in the vehicle. The moisture-absorbing filter plate 140 is made of silicone, and its outer wall is porous to facilitate air circulation. The moisture-absorbing filter plate 140 and the moisture-absorbing cylinder 150 can be integrally molded by injection molding.

[0018] Specifically, the ventilation opening 120 is circular and through-type, and multiple ventilation openings 120 are distributed in a linear array on the outer wall of the frame-100 to facilitate the evaporation and circulation of moisture inside the moisture absorption chamber.

[0019] More specifically, the outer walls on both sides of frame 100 are provided with threaded grooves 130, and the outer walls around frame 100 are provided with ventilation openings 120.

[0020] Furthermore, the outer wall of frame 200 is provided with screw holes 210, and screws are fitted into the inner wall of multiple screw holes 210. Multiple screws are fixedly connected inside the corresponding threaded grooves 130, which facilitates the fixing of frame 200 and frame 100.

[0021] Furthermore, the HEPA filter layer 230 and the antibacterial and antiviral layer 240 are sewn together, with the HEPA filter layer 230 positioned on the outer wall behind the antibacterial and antiviral layer 240, facilitating better air filtration and providing antibacterial and antiviral performance.

[0022] Furthermore, a moisture-absorbing cylinder 150 is adhered to the outer wall of the moisture-absorbing filter plate 140. Multiple moisture-absorbing cylinders 150 are arranged in a rectangular array on one side of the outer wall of the moisture-absorbing filter plate 140. This allows for better air circulation within the moisture adsorption chamber under the action of multiple moisture-absorbing cylinders 150, preventing moisture accumulation that could lead to bacterial growth in the filter element.

[0023] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0024] Working Principle: In actual use, a moisture-absorbing filter plate 140 is installed behind the pre-filter layer 110 of the filter element. The moisture-absorbing filter plate 140 can absorb moisture from the intake air. Moisture-absorbing cylinders 150 are installed on the outer wall of the moisture-absorbing filter plate 140. Due to their length, the multiple moisture-absorbing cylinders 150 fit snugly against the outer wall of the pre-filter layer 110 after installation, thus creating an airflow area between the moisture-absorbing filter plate 140 and the pre-filter layer 110. After being filtered by the pre-filter layer 110, the intake airflow can absorb moisture through the moisture-absorbing filter plate 140 and the multiple moisture-absorbing cylinders 150, reducing the direct entry of moisture into the driver's cabin and preventing discomfort caused by continuously increasing humidity. Furthermore, the moisture-absorbing filter plate 140 and the moisture-absorbing cylinders 150, combined with multiple vents and the diameter of the pre-filter layer 110 itself, can release moisture through the gaps when the air conditioning is not in use. The moisture is released to the outside, thus avoiding the problem of moisture being difficult to evaporate due to the stacking of multiple filter elements. After the moisture is adsorbed, the device passes through the antibacterial and antiviral layer 240 and the HEPA filter layer 230. The antibacterial and antiviral layer 240 can inhibit and kill bacteria, viruses and other microorganisms in the air, preventing them from growing and multiplying on the filter element. Combined with the reduction of humidity, it can better reduce the growth of bacteria and avoid secondary pollution, protecting the health of the people in the vehicle. The HEPA filter layer has a high filtration efficiency for bacteria, such as E. coli and Staphylococcus aureus, and can effectively intercept bacterial carriers and reduce the spread of bacteria in the air. For viruses, such as influenza viruses, although the virus itself is small in size, they usually attach to droplet nuclei or other particulate matter. The HEPA filter layer 230 can reduce the concentration of viruses in the air by filtering these carriers, reducing the risk of infection. This, together with the pre-filter layer and activated carbon filter layer, ensures the air filtration effect.
