A filter dust removal device

Abstract

The invention provides a filter dust removal device, comprising: a motor with an output shaft; an adapter piece with a connection end fixedly connected to the output shaft, and a mounting end opposite to the connection end; an elastic pressing piece, one end of which passes through the installation structure and The installation end is fixedly connected, and the other end is equipped with a brush for elastically pressing the brush toward the filter screen, so that the bristles of the brush are always in close contact with the filter screen. In the filter dust removal device of the present invention, when the motor starts to work, the elastic pressing part rotates with the output shaft, and then drives the brush to rotate. Since the elastic pressing part continues to press the brush toward the direction of the filter during the rotation, the brush Always maintain close contact with the filter, so even if the brush wears out due to long-term use, the elastic pressing piece can ensure the close contact between the brush and the filter, so that the brush can be used to the greatest extent, thereby avoiding waste , reducing the number of replacements.

Description

technical field [0001] The invention relates to the technical field of dust removal devices, in particular to a filter screen dust removal device. Background technique [0002] In some occasions where air exchange is required, in order to prevent external dust from entering, an air filter is generally installed on the air exchange path. After the air filter is used for a period of time, it is easy to accumulate dust. At this time, it is necessary to use a dust removal device to clean the air filter. [0003] The air filter net dedusting device in the prior art is as figure 1 As shown, it includes a dust removal motor 03 that is suitable for being fixedly arranged on the indoor side of the air filter screen 01. The dust removal motor 03 has a motor shaft 02 that protrudes from the air filter screen 01 and is located outdoors. The dust removal brush 04 is fixedly installed on the air filter screen 01. On the motor shaft 02, the bristles of the dust removal brush 04 are in cl...

Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the technical defects of frequent operation and waste of resources due to the frequent replacement of the brushes to ensure the dust removal effect after the brushes of the dust removal device in the prior art are worn out, and the dust removal effect becomes poor. Therefore, even after the bristles of the brush are worn out, the bristles can be kept in close contact with the outer wall of the filter, so that the dust removal effect is good and the filter dust removal device does not need to be replaced frequently
