Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning filters, in particular to an activated carbon filter element of a dual-effect filter for an automobile air conditioning. Background Art

[0002] Air conditioning filters have been widely used in modern cars to filter the air circulation inside and outside the car. At present, most vehicles have installed single-effect air conditioning filters with a filter layer. In order to further improve the air purification effect, some mid-to-high-end vehicles are equipped with dual-effect air conditioning filters that include both a filter layer and an activated carbon adsorption layer. The activated carbon adsorption layer in the dual-effect air conditioning filter can filter out pollen, dust and other dirt in the air.

[0003] China Publicly Authorized Invention: CN214597738U discloses an automotive air conditioning filter element, comprising a positioning block, a positioning pressure strip, a silicone strip, a support plate, a holder, and a compression spring. The positioning block is welded to the upper side of the rear end face of the positioning frame, the support plate is welded to the middle position of the inner wall of the positioning frame, the holder is mounted on the rear end face of the support plate, the compression spring is mounted inside the holder, a positioning pressure strip is mounted on the rear side of the compression spring, and a silicone strip is bonded to the rear end face of the positioning pressure strip. This design solves the problem of the filter element in the original automotive air conditioning filter being easily loosened during use and inconvenient to disassemble and install. The utility model has a reasonable structure, has extrusion positioning capability, is easy to disassemble and use, and is highly practical.

[0004] However, there are still certain problems with the device. In actual use, when the filter needs to be maintained or the filter element needs to be replaced, the user must first use external tools such as an Allen wrench to loosen the Allen bolts and pull them out. This step not only increases the complexity of the operation, but also requires the user to carry or prepare professional tools, which undoubtedly brings inconvenience to the daily maintenance and replacement of the filter. Therefore, we propose an automotive air-conditioning dual-effect filter activated carbon filter element to solve the above problems. Utility Model Content
