Single-row waste gas mask

Abstract

The invention discloses a single-row waste gas mask. The single-row waste gas mask comprises mask filter cloth, a right nasal tube opening, a right nasal tube, a mouth support, a mouth front tube, a mouth front tube opening, a mouth front single-row valve, a nose front single-row valve, a left nasal tube, a left nasal tube opening, a nose support and an elastic mask belt. The single-row waste gasmask is mainly characterized in that a certain gap is formed between the nase support and the left and right nasal tube openings; a certain gap is formed between the mouth support and the mouth fronttube opening; according to the principle of the Venturi effect, when people exhale with mouths or nostrils, waste gas cannot be emitted into the front cavity of the mouth; when people inhale with mouths or nostrils, people can only inhale fresh air entering from the gap between the mouth skin and the mouth front tube opening or fresh air coming from the gap between the nostrils and the left nasaltube opening and the right nasal tube opening, and the problems that an existing mask is difficult to breathe, waste gas circulates, the face is scorched and glasses are atomized are well solved.

Description

technical field [0001] The invention relates to the technical field of masks, in particular to an exhaust gas single-row mask. Background technique [0002] People will suffer from suffocation when wearing a mask every day. [0003] Why do masks hold your breath? A cloth-like mask only has a small area in front of the mouth and nose for ventilation, and most of the rest of the area is tightly attached to the face and cannot play the role of ventilation. The speed of inhalation and exhalation is slow, so you hold your breath; Regardless of whether there is an exhaust valve in the mask with a cavity, the exhaust gas exhaled from the mouth is always circulated in the cavity, because the content rate of exhaust gas exhaled by people is only 16%, which is equivalent to people being in a state of insufficient oxygen supply for a long time, so they hold their breath. In a nutshell, all the masks currently on the market either have a slow air supply speed or insufficient oxygen su...

AI Technical Summary

Problems solved by technology

In a nutshell, all the masks currently on the market either have slow air supply speeds or insufficient oxygen supply. In short, they all feel suffocated

[0004] In addition to suffocation, masks have many problems: poor heat dissipation, hot face; air leakage on both sides of the bridge of the nose, easy to fog glasses; filter cloth cannot be cleaned, high cost per use, etc.
