Haze-proof mask

Abstract

The invention provides a haze-proof mask, which relates to the technical field of dust prevention. The haze-proof mask comprises a mask body, wherein the two ends of the mask body are connected with ear buckling belts, the ear buckling belts are elastic bands with certain extending lengths, and a region, in contact with the face, of the inner surface of the mask body is provided with a pad body made of soft materials, so a pasting region is formed. The pad body has a certain radian, is designed according to the face shape characteristics of the human body, and can be tightly pasted on the mouth and nose part, the pasting position of the pad boy and the face part is subjected to thickness design according to the face characteristics, the regions positioned at the two sides of the naris are thicker and can be tightly pasted on the face, a region, pasted with the noise, of the inner surface of the mask body is provided with a support frame, and a filtering air bag is detachably arranged on the support frame and is used for filtering the gas. The haze-proof mask has the advantages that the traditional mask structure is changed, during the wearing, a three-dimensional effect is formed in the face part of the human body, the pasting is tight, the smooth breath can be ensured, users feel comfortable, and the haze-proof effect is good.

Description

technical field [0001] The invention relates to the technical field of dust prevention, in particular to an anti-smog mask. Background technique [0002] Masks can generally be divided into air filter masks and air supply masks. It is designed for people's health, and is used to prevent some visible or invisible substances that are harmful to the human body from filtering, so as not to have a bad influence on the human body. Masks have a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, wearing a mask has a very good effect when working in a polluted environment such as dust. From the perspective of human physiological structure, because the blood circulation of the nasal mucosa is very strong and the passages in the nasal cavity are very tortuous, the nasal hairs form a "barrier" for filtering. When air is sucked into the nostrils, the airflow forms a vortex in the tortuous channel, which warms the airflow inhaled ...

AI Technical Summary

Problems solved by technology

[0004] The traditional anti-smog mask does not fit the face tightly, and it is easy to leak air. The smog is still easily absorbed by the human body, and the filtering effect is poor; and the filter material used in the traditional filter mask has a small filtering area, which cannot meet the actual filtering needs.
