Filter element capable of releasing negative ions and closestool deodorization and purification device prepared by using filter element

Abstract

The invention relates to a filter element capable of releasing negative ions and a closestool deodorization and purification device prepared by using the filter element. The filter element comprises composite layers and a main frame; each composite layer consists of an upper partition layer, a filter material layer and a lower partition layer arranged in sequence at intervals; opposite surfaces ofevery two adjacent two layers are both surfaces undulating along a straight line in an X direction, and the spacing between the adjacent two layers is less than or equal to 8mm; the main frame is used for sealing a part, except inlets and outlets, of the composite layers; and the filter material layer comprises an adjacent filter material base layer and negative ion layer, wherein the negative ion layer consists of a network, negative ion powder and an adhesive. The prepared closestool deodorization and purification device comprises the filter element capable of releasing negative ions, a connecting pipe and a negative pressure suction device; one end of the connecting pipe communicates with inlets of the composite layers of the filter element one by one correspondingly; the other end ofthe connecting pipe communicates with the interior of a closestool; and outlets of the composite layers of the filter element communicates with the negative pressure suction device at a same time. Thefilter element of the invention can be used to efficiently decompose odor, and the closestool deodorization and purification device has a good deodorization and purification effect.

Description

technical field [0001] The invention belongs to the technical field of purification devices, and relates to a filter element capable of releasing negative ions and a toilet deodorization and purification device prepared therefrom. Background technique [0002] The toilet has become an indispensable tool in family life. At present, there are ordinary flush toilets and negative pressure flush toilets on the market. Although ordinary flush toilets are cheap, the odor gas is easy to spread in the bathroom when going to the toilet, which not only brings discomfort to people, but also causes certain harm to the environment. Impact: Negative pressure flush toilets have improved in terms of deodorization and sewage discharge, but they still cannot completely deal with the odor during the process of going to the toilet, and the negative pressure flush toilets are complex in structure and expensive. [0003] In order to solve the purification problem of bad smell in the process of go...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to solve the problem of insufficient contact between the filter material and the odor molecules and the large air resistance in the filter element for toilet in the prior art, and at the same time solve the problem of poor deodorization and purification effect of the toilet deodorization and purification device, and provide a Filter element releasing negative ions and toilet deodorizing purification device made therefrom
