Detachable filter element of filter

Abstract

A detachable filter element of a filter, the filter includes: a hollow cylinder, a plurality of regularly arranged small holes around the cylinder, a filter cover formed by a base with holes in the bottom and protruding inward; and In the filter cover, the filter element connected to the base; the filter element is composed of a cylindrical filter paper tube with multiple pleated structures; and the external set of filter paper tube is composed of a frame connecting the rings at both ends; it has a tube attached to the inner wall of the bracket shaped protective film; and the filter paper tube has openings at both ends, and an elastic belt is respectively set on the upper and lower ends of the filter paper tube to fix the pleated structure of the filter paper tube. Because the filter paper tube of the filter element is connected to the support by a single pendulum floating; the upper and lower ends of the filter paper tube are respectively covered with an elastic belt, and the elastic belt can be removed, so the filter paper tube can be disassembled, and the folds of the filter paper tube can be opened. It is easy to clean and convenient for users.

Description

technical field [0001] The invention belongs to the field of filter parts of vacuum cleaners, and in particular relates to a detachable filter core of a filter with detachable filter paper cylinder and support for easy cleaning. Background technique [0002] The vacuum cleaner is a cleaning and sanitary appliance used to remove dust from floors, carpets, walls, furniture, clothing and various gaps. [0003] According to the structure and shape of the vacuum cleaner, it is usually divided into an upright vacuum cleaner, a horizontal vacuum cleaner, and a portable vacuum cleaner. [0004] The structure of a vacuum cleaner generally includes a vacuum cleaner motor that generates suction by introducing current, a suction nozzle that forms an air path system, a suction hose, a filter, and a dust collection box that collects inhaled objects. [0005] The body of a horizontal vacuum cleaner generally includes a front cover, a rear cover and a bottom case assembly, wheels and other...

AI Technical Summary

Problems solved by technology

[0008] The filter with this structure has the following disadvantages: Since the two ends of the filter paper cylinder and the rings at both ends of the bracket are integral filter elements bonded together with glue, and the filter paper cylinder has a pleated structure, when the vacuum cleaner is used for a period of time, a large amount of dust will adhere to it. On the top, the folds of the filter paper tube cannot be fully opened and cleaned, and the dust in the gaps is difficult to clean, which makes the air permeability of the filter paper tube worse, seriously affects the filtering effect, and brings great inconvenience to users in use

[0012] However, the dust filter of the above structure has the following disadvantages: since the two ends of the filter body are not fixed, there is no lateral support to increase the strength of the wrinkles of the filter body and prevent the shape of the wrinkles from changing

The deformation of the filter body affects the filtering effect and reduces the dust collection efficiency

[0013] In addition, for the filters of the above two structures, the dust is only filtered through the filter paper tube or the filter body at one time, and the fine dust will be leaked, which reduces the filtering effect.
