AI Technical Summary

Technical Problem

The filter components of the existing automobile air conditioner air inlet passage are easily blocked after dust accumulates, affecting the air inlet effect and making it difficult to achieve self-cleaning.

Method used

A filter assembly including a telescopic portion, a filter portion and an elastic portion is designed. A suspended filter part is provided in the telescopic part. The filter part is composed of a filter net and a swing part. The swing part can swing back and forth relative to the filter net, and the elastic part connects the inner frame and the filter part, which can automatically reset when there is no external force. When the air conditioner is working, the air flow passes through the filter part and the swing part is blown up; when the air conditioner is stopped, the swing part hits the filter net, dust falls, and the reset of the elastic part pushes the filter part to shake, enhancing the dust removal effect.

Benefits of technology

Through the swing of the swing part and the reset of the elastic part, the filtering net is self-cleaned, dust accumulation is avoided, and the filtration efficiency of the air inlet passage of the air conditioner is improved.

Abstract

The invention provides an automobile air conditioner air inlet channel filtering assembly which comprises a telescopic part and a filtering part, the telescopic part comprises an inner connecting frame, a telescopic frame and an outer connecting frame, and the telescopic part is arranged in an automobile air conditioner air inlet channel; the filtering part is arranged in the telescopic part in a suspended mode, the filtering part comprises a filtering net and a swinging part, and the swinging part is arranged on the side, close to the inner connecting frame, of the filtering net and can swing front and back relative to the filtering net; the elastic part is arranged between the inner frame and the filtering part, and the elastic part can be compressed under stress and automatically reset when no external force exists; when air enters the air inlet channel of the automobile air conditioner, the telescopic part and the elastic part contract, the swing part is blown away from the filter screen by the inlet air, and when the inlet air of the air inlet channel of the automobile air conditioner is reduced or stopped, the telescopic part and the elastic part reset, and the swing part swings to knock the filter screen. The filtering assembly can realize self-cleaning of the filtering part by utilizing air inlet of the air inlet channel, and is simple in overall structure and convenient to mount, dismount and maintain.
