Toilet air purification device

Abstract

The invention discloses an air purification device in a toilet. The air purification device comprises a shell on which an air inlet and an air outlet are formed; a screening net on which a catechin and / or a nano-silver ion material layer are formed and which is arranged in the shell, close to the air inlet and used for screening the air entering the shell from the air inlet and sterilizing, deodorizing and purifying the air preliminarily; a photocatalytic purifier arranged in the shell and used for sterilizing, deodorizing and purifying the air in the last step for a second time and a blower arranged in the shell and being close to the air outlet is used for pumping the air into the shell and exhausting the air after the preliminary and secondary sterilization, deodorization and purification out of the shell from the air outlet. The air purification device in the toilet of the embodiment of the invention has simple structure, high purification efficiency, low cost and smooth air flow and is particularly suitable for the toilets and bathrooms.

Description

technical field [0001] The invention relates to air purification technology, in particular to an air purification device for a toilet. Background technique [0002] With the improvement of living standards, people's requirements for air quality in homes and public environments are also getting higher and higher. In some public places with a large flow of people, toilets and restrooms have become key areas where air quality problems need to be solved due to their special uses.

Problems solved by technology

Therefore, the effect of the catechin antibacterial filter layer installed at the air outlet is not obvious and increases the cost

[0006] In addition, since the filter unit and the catechin antibacterial filter layer are made separately, and the structure of the filter unit is very complicated, the manufacturing process increases, the cost increases, and the difficulty of installing and disassembling the filter unit and the catechin antibacterial filter layer increases.

At the same time, the installation space required in the air cleaner increases, resulting in an increase in the volume of the air cleaner
