Description

Technical Field

[0001] This utility model relates to the field of physics, and more particularly to automotive air conditioning filters, especially an automotive air conditioning filter with a rotatable and retractable frame. Background Technology

[0002] Automotive air conditioning filters, also known as cabin air filters, are commonly used in automotive heating, ventilation, and air purification systems to filter the air entering the vehicle from the outside. They remove impurities, dust, pollen, soot, and other fine particles, improving the quality of the in-vehicle environment, enhancing cabin air quality, reducing windshield fogging, and improving passenger comfort and safety. Current automotive air conditioning filters consist of a filter element and a frame around its perimeter. Replacing the filter is difficult due to the seamless fit between the filter and its mounting slot, requiring additional tools. This makes filter replacement inconvenient. Furthermore, the existing frame supports the filter element insufficiently, leading to deformation under high-flow conditions and affecting filtration efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide an automotive air conditioning filter with a rotatable and retractable frame, which solves the technical problems of inconvenient filter replacement and insufficient support strength of the frame at both ends of the filter element block in the prior art.

[0004] This utility model provides an automotive air conditioning filter with a rotatable and retractable frame and folded edge, including a filter element block. The filter element block is in the shape of a flat cuboid and is formed by folding filter paper. A frame is provided on the outer periphery of the filter element block. The frame is formed by a first side panel, a second side panel, a third side panel and a fourth side panel. The first side panel is parallel to the third side panel, the second side panel is parallel to the fourth side panel, and the upper edge of the first side panel is connected to a first folded edge. The first folded edge can rotate around the upper edge of the first side panel, and the width of the first folded edge is less than the height of the first side panel.

[0005] The lower edge of the first side panel is connected to a second folded edge, and the lower edge of the third side panel is connected to a third folded edge.

[0006] Alternatively, the lower or upper edge of the second side panel is connected to a second folded edge, and the lower or upper edge of the fourth side panel is connected to a third folded edge.

[0007] The second and third folds are both bent onto the lower side of the filter block.

[0008] Furthermore, the first and third side panels are perpendicular to the fold lines of the filter paper.

[0009] Furthermore, the second and fourth side panels are perpendicular to the fold lines of the filter paper.

[0010] Compared with existing technologies, this invention offers significant and positive advantages. When the filter needs to be removed, the first folded edge is rotated upwards by 90°, then used as a handle to pull the filter out of the mounting slot. This makes filter removal more convenient and improves the efficiency of filter replacement and maintenance. The second and third folded edges strengthen the ends of the filter element, preventing deformation under high flow conditions and ensuring stable filter performance. Attached Figure Description

[0023] The present invention will be further described below with reference to embodiments, but the present invention is not limited to these embodiments. Any similar variations using the present invention should be included within the protection scope of the present invention. The use of directions such as up, down, front, back, left, right, center, inside, and outside in the present invention is only for the convenience of clear description and is not intended to limit the technical solution of the present invention.

[0024] like Figures 1-12 As shown, this utility model provides an automotive air conditioning filter with a rotatable and retractable frame and folded edge, including a filter element block 1. The filter element block 1 is formed by folding filter paper. The filter element block 1 has a flat rectangular shape and is formed by folding filter paper. A frame is provided on the outer periphery of the filter element block. The frame is formed by a first side panel 4, a second side panel 2, a third side panel 5, and a fourth side panel 3. The first side panel 4 is parallel to the third side panel 5, and the second side panel 2 is parallel to the fourth side panel 3. The upper edge of the first side panel 4 is connected to a first folded edge 6, which can rotate around the upper edge of the first side panel 4. The width of the first folded edge 6 is less than the height of the first side panel 4.

[0025] The lower edge of the first side panel 4 is connected to a second folded edge 7, and the lower edge of the third side panel 5 is connected to a third folded edge 8.

[0026] Alternatively, the lower or upper edge of the second side panel 2 is connected to a second folded edge 7, and the lower or upper edge of the fourth side panel 3 is connected to a third folded edge 8;

[0027] The second fold and the third fold are both bent onto the lower side of the filter block 1.

[0028] Furthermore, such as Figure 1-8As shown, the first side panel 4 and the third side panel 5 are perpendicular to the fold lines of the filter paper.

[0029] Furthermore, such as Figure 9-12 As shown, the second side panel 2 and the fourth side panel 3 are perpendicular to the fold lines of the filter paper.

[0030] Furthermore, the width of the first folded edge 6 is 3-5mm smaller than the height of the first side panel 4.

[0031] Furthermore, the first side panel 4, the second side panel 2, the third side panel 5, and the fourth side panel 3 are all made of PET material (polyester resin). PET material is elastic, which can increase the sealing of the filter assembly, reduce air leakage, and reduce noise.

[0032] During installation, the first folded edge 6 should face the outside of the filter mounting slot. When the filter needs to be removed, rotate the first folded edge 6 upwards by 90°. Figure 4 In the state shown, the first folded edge 6 is used as a handle. By pinching the first folded edge 6, the filter is removed from the filter installation slot, making the filter removal operation more convenient and improving the efficiency of filter replacement and maintenance.

[0033] The second fold 7 and the third fold 8 strengthen the strength of both ends of the filter element block 1, preventing the filter element block 1 from deforming under high flow conditions and ensuring the stability of the filter's filtration performance.

[0034] air according to Figure 2 Enter the filter in the direction of the arrow shown, and follow... Figure 3 The arrow shown points away from the filter.

[0035] The rotation angle of the first folded edge 6 is -88° to 178°, such as Figure 2 As shown, when the filter is installed in the filter mounting slot, the first folded edge 6 automatically droops down and retracts due to gravity. The first folded edge 6 rotates at 178°. Installation instructions, maintenance instructions, and replacement instructions can be printed on the side of the retracted first folded edge 6 for easy reference by operators. Figure 5 As shown, the first folded edge 6 is rotated at an angle of -88°.

[0036] like Figure 6 , Figure 7 As shown, during the processing, a groove 9 is cut between the first side panel 4 and the first folded edge 6. The cutting depth is 0.4 to 0.7 times the thickness of the first side panel 4, so that the first folded edge 6 can rotate around the pivot formed at the groove 9.
