Filter screen and purifier with filter screen

Abstract

The invention relates to a filter screen and a purifier with the filter screen. A cross section of the filter screen is in an annular shape; and a buckle capable of rotating around an annular center line is arranged on the lower end surface of the filter screen, protrudes out of the lower end surface, perpendicularly extends from the lower end surface and forms a right-angle structure with a fastening part being parallel to the lower end surface. The purifier comprises an upper part and a lower part which can be detached; the filter screen is arranged on the filter screen installation end surface on the lower part; the upper part of the purifier covers on the filter screen and is connected with the lower part of the purifier; and a clamping groove capable of rotating around a center line of the purifier is formed in the installation end surface of the filter screen, is matched with the buckle on the filter screen, and is used for clamping the filter screen when the filter screen is rotated toward one direction, and loosening the filter screen when the filter screen is rotated backwards. The filter screen provided by the invention is directly connected with the lower part of the purifier through the buckle, so that a filter screen cover is omitted, the structure is simplified, and the filter screen is easy to install and disassemble, capable of saving time and fast.

Description

technical field [0001] The invention mainly relates to the field of purifiers, in particular to a filter screen and a purifier equipped with the filter screen. Background technique [0002] A purifier is a product that filters the air, in which the flow of the purified air is driven by the motor inside the machine to drive the wind wheel to generate air volume, and the core component of purifying the air is realized by the filter inside the machine. The filter needs to be replaced periodically and is a removable part. [0003] Most of the filter screens of purifiers on the market are directly placed inside the fuselage. There is no fixed connection between the filter screen and the machine, and the filter screen is easy to loosen, which will cause air leakage and affect the filtration efficiency. If you use a filter cover to cover the filter, you need to remove the filter cover and replace the filter. The filter cover of some circular filters is placed directly on the fuse...

AI Technical Summary

Problems solved by technology

The filter cover of some circular filters is placed directly on the fuselage without a fixed connection, and it is easy to loosen and cause abnormal noise

There is a part of the circular filter cover that is fastened and compressed at the same time, but this will cause inconvenient operation and complicated structure

[0004] There are also some filter products that need to be installed from the bottom of the machine. When disassembling the filter, the machine needs to be turned over, which is very troublesome and affects the user's operating experience and product practicability.
