A mask based on electrostatic adsorption and photocatalyst

Abstract

A mask based on electrostatic adsorption and photocatalyst belongs to the technical field of health protection. It includes a cover body and a belt rope, and is characterized in that the cover body has a five-layer structure: a photocatalyst filter layer, an outer active conductive carbon fiber cloth, a fine filter insulation layer, an inner active conductive carbon fiber cloth, and a flow-guiding and bonding filter layer; The outer and inner active conductive carbon fiber cloths are separated by a fine filter insulation layer sandwiched between the two, and there are drive modules, memory setting sheets, battery modules and wires between the two, and the outer and inner active conductive carbon fiber cloths pass through the wires respectively It is connected with the positive and negative poles of the drive module and the battery module to form an electrostatic adsorption mechanism; the photocatalyst filter layer is composed of 2-4 layers of gauze coated with composite nano photocatalysts; layer and its outer diversion layer. The mask comprehensively utilizes technologies such as photocatalyst disinfection, electrostatic adsorption, porous material adsorption and fabric dust resistance, which greatly improves its ability to filter air while ensuring that the mask is comfortable to wear.

Description

technical field [0001] The invention relates to a healthy and environment-friendly mask, in particular to a mask based on electrostatic adsorption and photocatalyst, and belongs to the technical field of health protection. Background technique [0002] Most of the current masks only have a certain filtering function. Some masks that claim to be able to deal with smog have poor filtering accuracy and cannot filter the tiny dust of PM2.5 level in the air. This type of mask mainly prevents pollutants from entering the human body by blocking. However, due to the needs of people's normal breathing, the breathing resistance of the mask should not be too large, which causes the contradiction between dust blocking efficiency and breathing resistance. Contents of the invention [0003] The purpose of the present invention is to solve the contradiction between the above-mentioned dust suppression efficiency and respiratory resistance. The invention provides a mask based on electros...
