Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to an automobile air filter with a noise reduction function. Background Art

[0002] Air conditioning filters have been widely used in modern automobiles for filtering the air circulation inside and outside the car. At present, most vehicles have been installed with a single-effect automobile air conditioning filter with a filter layer. In order to further improve the effect of purifying the air, some mid-to-high-end vehicles are equipped with a double-effect automobile air conditioning filter including a filter layer and an activated carbon adsorption layer. The existing double-effect automobile air conditioning filter is usually composed of a filter layer, an activated carbon adsorption layer and a support layer. The activated carbon adsorption layer is composed of activated carbon particles. The activated carbon adsorption layer is sandwiched between the filter layer and the support layer, and the filter layer and the support layer play a packaging role. Once the activated carbon adsorption layer is disassembled separately, it will scatter. In the automobile air conditioning filter of the prior art, the ordinary air conditioning filter can only play the role of inhibiting the entry of dust and particulate matter. The activated carbon series air conditioning filter can use the physical properties of the granular activated carbon itself in a very short period of time when the air passes through the obstruction to adsorb other tiny objects and more harmful substances in the air.

[0003] After searching, Chinese Patent Publication (Announcement) No. CN 203764041 U discloses an automobile air conditioning filter. The above patent has good filtering effect, can effectively filter automobile air conditioning dust and other substances, and can kill bacteria. However, when installing the current automobile air conditioning filter, most of them are directly inserted into the filter. Some incompatibility may cause looseness, affecting use. At the same time, the current filter may produce odor when in use, affecting normal use. Therefore, it is necessary to design an automobile air filter with noise reduction function.
