Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a combined air-conditioning filter element. Background Art

[0002] Existing automotive air conditioning filters consist of a filter plate that is repeatedly bent in an "N" shape, secured within a rectangular positioning frame. The outer edge of the filter plate is typically glued to the inner surface of the rectangular positioning frame. Because the filter plate is integral and has a wide spacing between its ends, when the air filter is installed in a car, the vehicle's wobbling on bumpy roads can cause the air filter to vibrate as well. Once the air filter is installed, the filter paper is very likely to tear. Utility Model Content

[0003] The technical problem to be solved by the utility model is that the existing filter plate is an integral type with a large spacing between the two sides, and the filter paper is easily torn due to the shaking of the car during driving.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A combined air conditioning filter element comprises a filter plate and a fixing frame, wherein the filter plate comprises a separate filter plate a and a filter plate b, a dividing plate is fixedly connected to the middle position of the fixing frame, and the filter plate a and the filter plate b are respectively arranged on both sides of the dividing plate;

[0006] The cross-sections of the left and right sides of the fixed frame are hook-shaped and arranged oppositely. A clamping frame is provided above the fixed frame for use therewith. The clamping frame includes hook-shaped side clips adapted to the left and right sides of the fixed frame. The opposite side of the side clips is fixedly connected to a pressure strip at the front and back sides of the fixed frame and the position of the dividing plate.

[0007] Furthermore, the inner surface of the fixed frame is fixedly connected to a limiting block on a side opposite to the dividing plate and close to the bottom of the fixed frame, as well as a symmetrical position on the opposite side of the pressure strip. A triangular limiting groove is provided on the side of the limiting block on the pressure strip opposite to the limiting block on the fixed frame and located at the position of the filter plate fold.

[0008] Working principle and beneficial effects: By dividing the filter plate into filter plate a and filter plate b and arranging them in sequence in the fixed frame in the area divided by the dividing plate, the span of the filter plate is reduced and the possibility of tearing due to shaking is reduced. The two ends of the filter plate are arranged in both sides of the fixed frame, and the side buckle plates are embedded in the inner surface of the side and fixed by snap fasteners. Compared with gluing, it is more stable and convenient to disassemble and clean. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The present invention can be better understood according to the following embodiments.

[0014] The structures, proportions, sizes, etc. illustrated in the drawings of the specification are only used to match the contents disclosed in the specification for the understanding and reading of those familiar with this technology. They are not used to limit the conditions for the implementation of the utility model and therefore have no substantial technical significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size should still fall within the scope of the technical content disclosed in the utility model without affecting the efficacy and purpose of the utility model. At the same time, terms such as "upper", "lower", "front", "back", and "middle" quoted in this specification are only for the convenience of description and are not used to limit the scope of the implementation of the utility model. Changes or adjustments in their relative relationships should also be considered as the scope of the implementation of the utility model without substantially changing the technical content.

[0015] like Figure 1-3 As shown,

[0016] A combined air conditioning filter element comprises a filter plate and a fixed frame 1, wherein the filter plate comprises a split filter plate a2 and a filter plate b3, a dividing plate 4 is fixedly connected to the middle position of the fixed frame 1, the filter plate a2 and the filter plate b3 are respectively arranged on both sides of the dividing plate 4, the cross-sections of the left and right sides of the fixed frame 1 are hook-shaped and arranged oppositely, a compression frame is provided above the fixed frame 1 for use therewith, the compression frame comprises hook-shaped side gussets 5 adapted to the left and right clamping engagement with the fixed frame 1, the side opposite to the side gussets 5 is located at the front and back of the fixed frame 1 and the position of the dividing plate 4 and is fixedly connected with a pressure strip 6, by dividing the filter plate into filter plate a2 and filter plate b3 and sequentially arranging them in the fixed frame 1 in the area divided by the dividing plate 4, the span of the filter plate is reduced, and the possibility of tearing due to shaking is reduced, and the filter plate is provided at both ends The ribs 5 are fixed to the sides of the fixing frame 1 and the side panels 5 are fixed by means of clips. Compared with gluing, they are more stable and convenient for disassembling and cleaning. In order to limit the stability of the filter plates a2 and b3 on the side where they are attached to the side of the fixing frame 1 and the dividing plate 4, without using glue, a limit block 7 is provided. The specific structure is as follows: the side of the inner surface of the fixing frame 1 opposite to the dividing plate 4 and close to the bottom of the fixing frame 1 and the symmetrical position of the side opposite to the pressure strip 6 are fixedly connected to the limit block 7. The limit block 7 on the pressure strip 6 is opposite to the limit block 7 on the fixing frame 1 and is located at the position of the filter plate fold. A triangular limit groove is provided. This structure can ensure the stability of the limit of the filter plates a2 and b3 and is also convenient for disassembly.
