AI Technical Summary

Benefits of technology

This patented technology describes improvements on filters used inside vehicles that improve their performance by absorbing certain substances from outside sources like vaporized hydrocarbons released during car use. These modifications include adding activated charcoal particles into them instead of traditional particulate materials, modifying pore size distribution, treatments involving chemical reactions, dipping/dryting techniques, and others. By doing this, these modified filters are able to absorb different types of gaseous components efficiently without causing damage when they enter the passenger compartment. Additionally, there're no risk of losing valuable material caused by burning activated coke. Overall, these technical results lead to better quality control over cars equipped with these filters.

Problems solved by technology

This technical problem addressed in this patents relates to finding ways to efficiently remove or reduce harmful gas emissions during vehicles without affect their performance negatively. Existing methods involve adding expensive catalyst materials like platinium(Pt). These techniques require complex processes involving high temperatures and pressures, leading to potential health concerns due to exposure to heavy metal particles.

Abstract

The invention provides an automobile air conditioner filter (11) used for an automobile air conditioner (1), wherein the automobile air conditioner filter comprises at least three filter layers including a first filter layer (111), a second filter layer (1112) and a third filter layer (113). The second filter layer is arranged between the first filter layer and the third filter layer, the first filter layer, the second filter layer and the third filter layer are connected with one another in a hot-pressing connection manner, and the second filter layer comprises an adsorbing material at leastpartially made of active carbon fiber. The invention also provides a method (2) for manufacturing the automobile air conditioner filter (11). The method comprises the following steps: carrying out hot-pressing connection treatment (201) on the first filter layer (111), the second filter layer (112) and the third filter layer (113) so as to form a filter base material; carrying out pleating treatment (202) on the filter base material which is hot-pressed and connected together; and carrying out cutting treatment (203) on the filter base material through pleating treatment.
