Description

Technical Field

[0001] This utility model relates to the field of automotive parts, specifically to a structure for an automotive air conditioning filter. Background Technology

[0002] The main function of an automotive air conditioning filter is to filter the air entering the vehicle from the outside, ensuring clean and healthy air inside the car. For example, Chinese patent CN219423972U provides a self-cleaning automotive air conditioning filter, including a frame with a sponge layer bonded to the outer edge of the frame. The sponge layer fills the gap between the frame and the air conditioning filter mounting bracket. The filter is built into the frame and has the same structure as existing filters, being folded. It should be understood that the filter is not limited to a parallel fold at the bend; the bend can also be wavy to increase the filter's strength. A clamping mechanism is engaged with the filter to fix the bend, ensuring consistent gaps between the bends and preventing significant deformation of the filter under wind and dust impact. Filters like those in the prior art require periodic removal for blow-drying to remove dust. During blow-drying, the clamping mechanism needs to be removed, and blow-drying alone is sometimes insufficient to completely remove dust and foreign matter from the filter's gaps. Utility Model Content

[0003] The purpose of this utility model is to provide a structure for an automotive air conditioning filter element, which solves the problem that in the prior art, the filter element needs to be periodically removed for blow-drying to remove dust, the clamping mechanism needs to be removed during blowing, and it is sometimes difficult to clean the dust and foreign objects in the gaps of the filter element by blow-drying alone.

[0004] To achieve the above objectives, this utility model provides an automotive air conditioning filter structure, which includes a housing, a pleated filter element disposed inside the housing, a pressing frame detachably disposed at the upper end of the housing, and sliding groove structures formed on both sides of the pressing frame. A limiting strip is slidably disposed at both ends within the sliding groove structures, and multiple spacers are spaced apart on the limiting strip, each spacer being located within the gap of the pleated filter element. Locking screws are respectively disposed at both ends of the sliding groove structures, such that the locking screws can limit the limiting strips at both ends of the sliding groove structures to prevent displacement of the limiting strips.

[0005] Preferably, the bottom of the outer casing has an opening, and a first annular structure is formed at the opening, the first annular structure being in contact with the bottom of the folded filter element.

[0006] Preferably, the inner wall of the pressing frame is formed with a second annular structure, and the second annular structure is in contact with the upper end surface of the outer shell.

[0007] Preferably, both ends of the limiting strip pass through the groove structure and are connected to a slider structure.

[0008] Preferably, the side of the pressing frame is fastened to the side of the housing by screws.

[0009] Preferably, the surface of the spacer is covered with a rubber sleeve.

[0010] Beneficial Effects: This utility model provides an automotive air conditioning filter structure, which includes a housing, a pleated filter element disposed within the housing, a pressing frame detachably disposed at the upper end of the housing, and sliding groove structures formed on both sides of the pressing frame. A limiting strip is slidably disposed at both ends within the sliding groove structures, and multiple spacers are formed at intervals on the limiting strip, each spacer located within the gaps of the pleated filter element. Locking screws are respectively disposed at both ends of the sliding groove structures, allowing the locking screws to limit the limiting strips at both ends of the sliding groove structures, thus preventing displacement of the limiting strips. The automotive air conditioning filter structure provided by this utility model fixes the pleated filter element through the housing and pressing frame, and the spacers on the limiting strips widen the gaps between the pleated filter elements, preventing deformation of the pleated filter element and thus reducing the filtration effect. During blow-blowing cleaning, the locking screws can be removed, the limiting strips slid, and the spacers are used to scrape off dust and foreign matter adhering to the gaps, improving the cleaning effect in conjunction with blow-blowing.
