[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] To further understand the content of the present utility model, the present utility model will be described in detail in conjunction with the accompanying drawings.

[0026] Combined with Figure 1 , a composite automotive air conditioner filter of the present utility model includes a filter frame 1. Two groups of non-woven fabric filter elements 3 for filtering are attached to both sides of the filter frame 1. A disassembly and installation sealing frame 2 is press-fitted on one side of the non-woven fabric filter element 3. The filter frame 1 includes a thick frame 11. The disassembly and installation sealing frame 2 includes a rectangular frame 21 attached to the side of the thick frame 11. A row of five trapezoidal blocks 22 are fixedly arranged side by side on one side of the rectangular frame 21. The trapezoidal blocks 22 are arranged in two rows at both ends of the rectangular frame 21. The non-woven fabric filter element 3 includes side pressure filter elements 31 arranged at both ends. A filter element assembly 32 is connected between the two groups of side pressure filter elements 31. The filter element assembly 32 is composed of outer sealing cloths 321 arranged on both sides, multiple connecting cloths 322 vertically connected between the outer sealing cloths 321, and diagonal cloths 323 diagonally connected between adjacent connecting cloths 322.

[0027] Specifically, the rectangular frame 21 is connected to the trapezoidal block 22. The filter element assembly 32 is squeezed from both sides by the trapezoidal block 22 into an S-shaped form. The side pressure filter element 31 is fixed by being squeezed by the disassembly and installation sealing frame 2. The S-shaped setting increases the filtering area of the non-woven fabric filter element 3 and expands the space. Moreover, the disassembly and installation sealing frames 2 on both sides of the thick frame 11 fix two groups of non-woven fabric filter elements 3. The stacked setting enhances the filtering effect. The outer sealing cloth 321 has a preliminary filtering effect. The connecting cloth 322 is used to connect the outer sealing cloths 321 on both sides and the diagonal cloth 323. The diagonal setting of the diagonal cloth 323 isolates the upper and lower sides. And this diagonal setting enables a space to be reserved between the two groups of outer sealing cloths 321, so that the dust of the filter can be enclosed in the filter element assembly 32, resulting in a relatively high dust removal rate when the non-woven fabric filter element 3 is replaced and reducing the cleaning pressure.

[0028] The following further describes the present utility model in conjunction with embodiments.

[0029] Embodiment 1:

[0030] Combined with Figures 2 - 5 , the filter frame 1 further includes side shift frames 12 fixedly arranged on both sides of the thick frame 11 and a center frame 13 fixedly arranged inside the thick frame 11. The setting of the two groups of side shift frames 12 facilitates the sliding of the thick frame 11 to the filter fixing position. The center frame 13 is arranged in the center. While separating the two groups of non-woven fabric filter elements 3, it cooperates with the trapezoidal block 22 to jointly realize the side fixing of the non-woven fabric filter element 3.

[0031] The filter frame 1 further includes struts 14 fixedly arranged on both sides of the thick frame 11. There are four groups of struts 14 arranged side by side, and the four groups of struts 14 are used to realize the bending positioning of the non-woven fabric filter element 3.

[0032] The filter frame 1 further includes four groups of screws 15 inserted at the four corners of the thick frame 11. The four groups of screws 15 are inserted at the four corners of the rectangular frame 21, and the four groups of screws 15 are used to connect the rectangular frame 21 and the thick frame 11.

[0033] On the side where the rectangular frame 21 is attached to the side pressure filter element 31, a pressure increasing block 211 is provided. The pressure increasing block 211 squeezes the side pressure filter element 31 to ensure the sealing of the side fixing of the non-woven fabric filter element 3.

[0034] Embodiment 2:

[0035] Combined with Figure 5 and Figure 6, the side-pressure filter element 31 and the filter element assembly 32 are components made of the same structure. When the side-pressure filter element 31 is fixed, its upper end is squeezed against the pressurizing block 211, and the side-pressure filter element 31 is pressed by the pressurizing block 211, so that the side seal of the non-woven fabric filter element 3 is relatively good. The centering frames 13 and trapezoidal blocks 22 on both sides of the filter element assembly 32 are squeezed and fixed. The side-pressure filter element 31 and the filter element assembly 32 are matched, and all around is sealed, and the disassembly and installation frame 2 is detachable, so that the non-woven fabric filter element 3 is easy to replace.

[0036] The outer filter openings 3211 are arranged side by side on the outer sealing cloth 321. The outer filter openings 3211 are arranged between the two connecting cloths 322. The arrangement of the outer filter openings 3211 allows larger dust to enter between the two outer sealing cloths 321 and be adsorbed by the non-woven fabric filter element 3.

[0037] The inner filter openings 3231 are arranged side by side on the inclined cloth 323. The opening diameter of the inner filter openings 3231 is smaller than that of the outer filter openings 3211. The inner filter openings 3231 separate the outer sealing cloths 321 on both sides to filter smaller dust.

[0038] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0039] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
