Nasal cavity composite respirator for assisting purification of micro-fine suspension particles

Abstract

The invention relates to the technical field of air filtering devices, and in particular relates to a nasal cavity composite respirator for assisting purification of micro-fine suspension particles. The nasal cavity composite respirator comprises two elastic filtering bodies, filter discs and connectors, wherein the two elastic filtering bodies correspondingly extend into two nasal cavities; the filter discs are arranged at the bottom parts of the elastic filtering bodies; an elastic disc for stopping reverse outlet air is arranged in the center of each filter disc; the elastic filtering bodies are hollow elastic bodies, each comprising a front end supporting wall, a neck part supporting wall and a bearing supporting wall which are sequentially arranged from top to bottom; bosses are arranged at two ends of the bottom parts of the bearing supporting walls; grooves fitting the bosses are formed in two ends of the filter discs. The nasal cavity composite respirator is simple in structure and convenient to operate; the elastic filtering bodies are high in comfort and high in air permeability, and air can enter nares only through the filter discs; with the adoption of the nano-scale thin film filter discs, bacteria, virus and other harmful substances can be stopped at the outside of a filtering materials, and thus the filtering effect is good.

Description

technical field [0001] The invention relates to the technical field of air filtering devices, in particular to a nasal compound respirator used for auxiliary purification of fine suspended particles. Background technique [0002] The composition of suspended particles is very complex and comes from a wide range of sources. These suspended particles can penetrate the barrier to reach the bronchi and alveoli, and pass through the lungs to affect other organs. Wearing a mouth and nose mask is the first line of defense to protect human health. However, at present Conventional mouth and nose masks cannot simultaneously have high air tightness, high comfort and high air permeability. The invisible nasal masks currently available on the market have to be inserted into the nostrils when wearing them, causing the nostrils to The foreign body sensation in the mask is relatively increased, and the high air tightness between the nostril and the nasal mask cannot be effectively ensured. ...
