Description

Technical Field

[0001] This utility model relates to the field of vehicle air conditioning filter technology, and in particular to a vehicle air conditioning filter with reinforced edge sealing. Background Technology

[0002] In today's booming automotive industry, in-vehicle air quality is receiving increasing attention from consumers. As a key component in regulating the in-vehicle air environment, the performance of the in-vehicle air conditioning system directly affects the health and comfort of passengers. The in-vehicle air conditioning filter, as an important part of the air conditioning system, plays a crucial role in filtering dust, pollen, bacteria, harmful gases, and other impurities from the air entering the vehicle, ensuring fresh and clean air inside the car.

[0003] For example, a multi-layer vehicle air conditioning filter with publication number CN220878136U includes a support assembly, a filter assembly, and an adsorption assembly. The support assembly supports the filter assembly and the adsorption assembly, and the adsorption assembly is located in the middle of the filter assembly. The filter assembly filters the gas that flows through the air conditioning filter from top to bottom, and the adsorption assembly adsorbs the gas that flows through the air conditioning filter from top to bottom. This utility model achieves the function of filtering and adsorbing air flowing into the vehicle in a multi-layer manner. Moreover, even if the upper filter plate is accidentally damaged, the lower filter plate can still filter the air. It not only has the function of adsorbing harmful gases and odors in the air, but also realizes the function of reusing some components. However, when installing the air conditioning filter, the seal between its edge and the air conditioning housing is often not tight enough. Air can enter the vehicle directly through these gaps without being fully filtered, resulting in a significant reduction in the filtration effect and inconvenience.

[0004] Therefore, there is a need to design a vehicle air conditioning filter element with enhanced edge sealing that can seal the edges during installation and improve the sealing effect. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies where the seal between the edge of the air conditioning filter and the air conditioning housing is often not tight enough during installation, allowing air to enter the vehicle directly through these gaps without being fully filtered, thus greatly reducing the filtration effect, this utility model provides an edge-sealed vehicle air conditioning filter that can enhance the sealing effect by sealing the edge during installation.

[0006] The technical solution is as follows: A vehicle air conditioning filter element with reinforced edge sealing includes an outer frame, a fixing plate, screws, a fixing frame, a filter plate, a filter screen, a first slider, a second slider, a sealing component, and a compression component. The fixing plate is detachably connected to the front of the outer frame by multiple screws. Two sets of first sliders are slidably engaged inside the outer frame, each set consisting of two left and two right first sliders. The first sliders in the same set are connected to the fixing frame, and the filter plate is connected inside each fixing frame. Two second sliders are slidably engaged in the middle of the outer frame, and the filter screen is connected between the second sliders. The outer frame is provided with a sealing component that can seal the edges during installation, and the sealing component is provided with a compression component that can squeeze and push the outer frame during installation.

[0007] Furthermore, the sealing assembly includes a first compression block, a second compression block, a spring, a telescopic rod, and a connecting plate. The first compression block is connected to both the left and right sides of the outer frame, and the connecting plate is slidably connected to the rear of the outer frame. The telescopic rod is connected to the rear sides of both the left and right sides of the connecting plate. The second compression block is connected between the telescopic ends of the telescopic rod, and the spring is connected between the left and right sides of the second compression block and the connecting plate.

[0008] Furthermore, both the first extrusion block and the second extrusion block are made of flexible material.

[0009] Furthermore, the first extrusion block has two extrusion grooves, one at the front and one at the back.

[0010] Furthermore, it also includes an extrusion assembly, which includes a connecting frame and a push block. The connecting plate is connected to two upper and lower connecting frames on both the left and right sides, and push blocks are connected to both the front and rear parts of the connecting frame. The push blocks are in contact with the adjacent first extrusion block.

[0011] Furthermore, all push blocks are wedge-shaped structures.

[0012] The beneficial effects are as follows: This utility model inserts the outer frame into the vehicle air conditioner housing, which drives the second extrusion block to move forward. The spring contracts, which drives the connecting plate, connecting frame and push block to move forward. The push block moves and extrudes the first extrusion block, which moves the first extrusion block outward. This makes both the first extrusion block and the second extrusion block contact the inner side of the air conditioner housing, thus achieving the ability to seal the edges during installation and enhancing the sealing effect.

Detailed Implementation

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0019] A type of automotive air conditioning filter with reinforced edge sealing, such as Figure 1 and Figure 2 As shown, it includes an outer frame 1, a fixing plate 2, screws 21, a fixing frame 3, a filter plate 4, a filter screen 5, a first slider 6, a second slider 7, a sealing component, and a pressing component. The front of the outer frame 1 is detachably connected to the fixing plate 2 by four screws 21. Inside the outer frame 1, two sets of first sliders 6 are slidably engaged, each set consisting of two left and right first sliders 6. The first sliders 6 in the same set are connected to the fixing frame 3. The filter plate 4 is connected inside the fixing frame 3. The middle of the outer frame 1 is slidably engaged with two left and right second sliders 7. The filter screen 5 is connected between the second sliders 7. The outer frame 1 is provided with a sealing component, and the sealing component is provided with a pressing component.

[0020] like Figures 2-4 As shown, the sealing assembly includes a first compression block 8, a second compression block 9, a spring 10, a telescopic rod 101, and a connecting plate 11. The first compression block 8 is connected to both the left and right sides of the outer frame 1, and the connecting plate 11 is slidably connected to the rear of the outer frame 1. The telescopic rod 101 is connected to the rear side of both the left and right sides of the connecting plate 11. The second compression block 9 is connected between the telescopic ends of the telescopic rod 101. Both the first compression block 8 and the second compression block 9 are made of flexible material and have a certain elasticity, which facilitates sealing. The first compression block 8 has two compression grooves 14 on both the front and rear sides. The second compression block 9 is connected to the connecting plate 11 on both the left and right sides by springs 10.

[0021] like Figure 4 As shown, it also includes an extrusion assembly, which includes a connecting frame 12 and a pusher block 13. The connecting plate 11 is connected to two upper and lower connecting frames 12 on both the left and right sides. The connecting frame 12 is connected to the front and rear parts of the connecting frame 12. The pusher blocks 13 are all wedge-shaped structures to facilitate extrusion. The pusher blocks 13 are all in contact with the adjacent first extrusion block 8.

[0022] When using this utility model, firstly, the fixing frame 3 is inserted into the outer frame 1 by the first slider 6, then the filter screen 5 is inserted into the outer frame 1. Then, the fixing piece 2 is fixed to the front of the outer frame 1 by the screw 21, limiting the filter plate 4 and filter screen 5 on the fixing frame 3. Subsequently, the outer frame 1 is inserted into the vehicle air conditioner housing, causing the second extrusion block 9 to be extruded, which moves the second extrusion block 9 forward, causing the telescopic rod 101 and spring 10 to retract, which in turn moves the connecting plate 11, connecting frame 12 and push block 13 forward. The push block 13 moves forward and extrudes the first extrusion block through the extrusion groove 14. Pressing block 8 drives the first pressing block 8 to move outward, so that both the first pressing block 8 and the second pressing block 9 contact the inner side of the air conditioner housing. Then, the cover plate of the air conditioner housing is closed. Under the action of spring 10, the fixing piece 2 contacts the cover plate of the air conditioner housing, sealing the gap between the edge of the outer frame 1 and the air conditioner housing. This allows for edge sealing during installation and enhances the sealing effect. When it is necessary to replace the filter plate 4 and filter screen 5, the screw 21 can be removed, the fixing piece 2 can be removed, and then the fixing frame 3 and filter screen 5 can be moved forward and removed for replacement.
