The direct replacement of the filter screen will lead to waste of resources and increase the cost; for the cleaning of the filter screen, there is currently no special device, and the commonly used filter screen cleaning method is to manually use high-pressure air gun blowing, physical tapping or washing and other physical methods to remove the surface adhering to the filter. dust. If a high-pressure air gun is used to blow the dust, the dust will scatter around during the treatment process, which will have a serious impact on human health and the surrounding environment; if physical tapping is used to clean up the dust on the filter screen, there will be high labor intensity, dust splashes affecting human health, and cleaning. The problem is that the effect is not actually good; if the water washing filter is used, there is a problem of polluting the water body and wasting water resources for multiple cleanings, and many filters do not support the design of water washing. To sum up, how to solve the problems that the cleaning of the filter screen is likely to cause environmental pollution and high labor intensity has become a technical problem to be solved urgently by those skilled in the art.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

The utility model provides an air filter structure with a dust removal function, which includes a fan assembly 3, a filter screen assembly 1 and a filter screen rotation assembly 2 arranged in sequence from top to bottom. Specifically, the filter screen assembly 1 includes The filter screen 101 and the casing 102 arranged outside the filter screen 101, wherein the side wall of the casing 102 is provided with through holes for preliminary filtering of large particles in the air, the filter screen 101 is a cylindrical structure, and the inner cavity of the cylinder 101 is used for Clean air is circulated; the filter screen rotating assembly 2 includes a bottom case 201 and a motor 202, the bottom case 201 is a disc structure, a cavity for installing the motor 202 is arranged in the middle of the bottom case 201, and the rotating shaft of the motor 202 passes through the cavity and The bottom of the filter screen 101 is fixedly connected to drive the filter screen 101 to rotate. The bottom of the bottom shell 201 is provided with a positioning ring 2011 for installing the shell 102, and the side wall of the bottom shell 201 is provided with a special-shaped groove 2012 to be fixed and clamped with the shell 102, which is convenient for the shell 102; the fan assembly 3 includes a fan 301, a fan fixing frame 302 and an upper casing 303, the fan fixing frame 302 is arranged on the top of the outer casing 102, and the middle of the fan fixing frame 302 is provided with an air guide cavity 3021, and the air guide cavity 3021 In order to connect the inner cavity of the filter screen 101 with the air inlet of the fan 301 , the side wall of the upper shell 303 has a through hole and is covered outside the fan 301 , and is fixedly connected with the fan fixing frame 302 .
