Description

A single-row mask for exhaust gas

technical field

The invention relates to the technical field of masks, in particular to a single-row exhaust gas mask.

Background technique

People will suffer from suffocation when wearing masks every day.

Why is the mask holding your breath? A cloth-like mask only has a small area in the front of the mouth and nose for ventilation, and most of the rest of the area is tightly attached to the face and cannot achieve ventilation. The speed of inhalation and outflow is slow, so hold your breath; No matter whether the mask with a cavity has an exhaust valve or not, the exhaust gas exhaled from the mouth always circulates in the cavity, because the content of the 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 masks currently on the market are either slow in air supply or insufficient oxygen supply, in short, they feel suffocated.

In addition to suffocation, masks also have many problems: poor heat dissipation, and the face feels hot; air leaks on both sides of the bridge of the nose, which are easy to atomize glasses; filter cloth cannot be cleaned, and the cost of a single use is high, etc.

I know that humans have been using masks for thousands of years, and it is indeed not difficult to improve the wearing comfort of them.

Is there any way to solve the above problem? I have tried as follows.

SUMMARY OF THE INVENTION

In view of the deficiencies of the prior art, the present invention provides a single-row exhaust gas mask, which solves the problems in the above-mentioned background technology.

We know that, according to the Venturi principle, when the jet air enters through a narrow duct, the jet air will create a negative pressure around the inlet of the duct and carry a certain amount of open-edge air into the duct.

In order to solve the above-mentioned problems, the present invention is realized through the following technical solutions:

An exhaust gas single-row mask, comprising a mask filter cloth, a right nasal tube provided with a right nasal tube opening, a mouth support, a front mouth tube provided with a front mouth tube, a single-row valve in front of the mouth, a single-row valve in front of the nose, and a device. There is a left nasal tube, a nose support and an elastic mask belt with a left nasal tube mouth. A front-mouth tube and a front-mouth single-row valve are set in the middle and lower positions of the mask filter cloth, and a front-nose single-row valve is set at the middle and upper position of the mask filter cloth. , Left nasal tube and right nasal tube, the mouth bracket is set on the outside of the mouth of the front of the mouth, the front of the mouth is set on the inner side of the single-row valve in front of the mouth, the left and right nasal tubes are set on the inner side of the single-row valve in front of the mouth, and the The exhaust valve is adapted to connect with the front mouth tube, and the single row valve in front of the nose is adapted to connect with the left nasal tube and the right nasal tube. There is a certain gap between the nose bracket and the left and right nasal tube orifices. When exhaling, the air around the mouth of the left nasal tube and the mouth of the right nasal tube will be inhaled into the left nasal tube and the right nasal tube and then discharged through the single row valve in front of the nose; when the wearer inhales through the nostrils, due to the single row valve in front of the nose. It has been closed, the exhaust gas in the left nasal tube and the right nasal tube is in a state of no passage, and the wearer can only inhale the fresh air from the gap between the nose bracket and the left nasal tube orifice and the right nasal tube orifice; There is a certain gap between the mouths. When the wearer exhales with the mouth, the air around the mouth of the mouth will be inhaled into the front of the mouth and then discharged through the single-row valve in front of the mouth; The exhaust valve has been closed, the exhaust gas in the front pipe of the mouth is in a state of no passage, and the wearer can only inhale the fresh air coming in from the gap between the mouth bracket and the mouth of the front nozzle, so as to realize the efficient replacement of fresh air intake and 100% exhaust gas discharge Effect.

Optionally, the mouth orifice of the mouth, the left nasal orifice, and the right nasal orifice are in the shape of a circle, an ellipse, a lip or a square.

Optionally, the left nasal tube and the right nasal tube are integrally formed, or the left nasal tube and the right nasal tube are designed to be the same branch tube located opposite to the left and right nostrils of the wearer.

Optionally, the left nasal tube, the right nasal tube and the front mouth tube are an integral assembly, or an integrally formed component.

Further, the front mouth tube is designed as a venturi tube with a certain gap from the wearer's lips.

Further, the left nasal tube and the right nasal tube are designed as Venturi tubes with a certain gap away from the wearer's nose.

Further, the single-row valve in front of the mouth and the single-row valve in front of the nose are one-way exhaust valves, and the single-row valve in front of the mouth and the single-row valve in front of the nose are partially exposed on the outside of the filter cloth of the mask.

Compared with a cloth mask or a mask with a cavity in front of the mouth, the exhaust gas single-row mask of the present invention has the following advantages:

1. No matter what the exhaust method is, the exhaust gas will never be distributed in the cavity of the filter cloth of the mask. The current masks on the market can be intuitively classified into two types: a cloth-like medical mask, the cavity in front of the mouth and nose is small, but the mask filter cloth that actually acts as a filter has a small area, and the air in and out is not smooth; the front of the mouth and nose is not smooth. There are many types of masks with larger cavities, and some also have exhaust valves or independent filter boxes. In short, all masks on the market now have cavities, large or small. When people exhale, the exhaust gas with only 16% oxygen content always occupies the cavity in front of the mouth and nose. The exhaust gas is also sucked in first. The oxygen content in the atmosphere is 21%, and the exhaust gas with nearly a quarter of the oxygen content is always circulated when breathing. Therefore, people always feel suffocated after wearing a mask. According to the above structure and the Venturi principle of the single-row exhaust gas mask of the present invention, when people exhale exhaust gas through the nostrils, mouth or nose and mouth at the same time, the air around the mouth of the left nasal tube and the mouth of the right nasal tube will always be inhaled into the left nasal tube. , The right nasal tube is discharged through the single-row valve in front of the nose; the air around the mouth of the mouth in front of the mouth will always be inhaled into the front tube of the mouth and then discharged through the single-row valve in front of the mouth, so the exhaust gas will never be distributed in the mask filter cloth in the cavity.

2. No matter what way you inhale, all you inhale is fresh air that has been filtered. There are many changes in the way people inhale. In addition to the inhalation habits, generally speaking: inhale through the nostrils when it is more leisurely; inhale through the mouth when doing physical work; inhale through the nose and mouth at the same time when doing heavy physical work. The masks with a large cavity in front of the mouth on the market currently occupy the cavity in front of the mouth and nose no matter what the inhalation is, the exhaust gas with only 16% oxygen content always occupies the cavity in front of the mouth and nose, and the exhaust gas in the cavity is also inhaled first, and so on. . The exhaust gas of the single-row mask of the invention will never be distributed in the cavity of the filter cloth of the mask. When people inhale through the nostrils, although there is a very small amount of waste gas hidden in the left and right nasal tubes, the single-row valve in front of the nose is closed at this time, and the waste gas cannot come out. The fresh air that has been filtered and has an oxygen content of 21% enters into the gap between the left and right nasal canal openings; when people inhale through their mouths, although there is an extremely small amount of waste gas hidden in the front of the mouth tube, But at this time, the single-row valve in front of the mouth is in the closed state, and the exhaust gas also cannot come out. Air.

3. You will never feel the problem of breathing difficulty at any time. A cloth-like mask actually has too little area for filtering, and the air flow is slow, making it difficult to breathe after wearing it for a long time; the exhaust gas with a large cavity in front of the mouth hides the exhaust gas, and the exhaust gas with extremely low oxygen content is always in the cavity. Internal circulation, it also feels difficult to breathe after wearing it for a long time. The single-row exhaust gas mask of the invention has a front mouth tube, a left nose tube and a right nose tube to support the middle part of the filter cloth of the mask, and the actual filtering area is greatly increased, ensuring sufficient supply of fresh air when inhaling; and no exhaust gas is emitted when exhaling In the cavity, the whole cavity is filled with fresh air containing 21% oxygen at any time, so it is easy and comfortable no matter how long you wear it.

Fourth, no matter what time the face will not have a burning sensation. At present, all masks on the market have cavities in front of the mouth and nose. When people exhale exhaust gas, the cavity immediately presents a positive pressure state, and due to the relatively high temperature of the exhaled gas in the human body, as long as the air leaks on the face There will be a burning sensation everywhere. Whether the single-row exhaust gas mask of the present invention is exhaled through the nostrils or through the mouth, the cavity of the mask always presents a negative pressure state, neither exhaust gas is emitted in the cavity, nor the phenomenon of high-temperature exhaust gas running around.

Five, no matter when the glasses will not be atomized. At present, most intellectuals wear glasses, and there are many people in the medical industry who wear glasses and there is a high probability that they need to wear masks to go to work. The bridge of the nose protrudes from the face, and it is difficult to seal the edges of the mask. The possibility of leakage of exhaust gas from the left and right sides of the bridge of the nose is extremely high, and the leaked hot air is directly blown against the glasses, and the lenses are immediately blurred, which seriously affects people's vision. . Whether the single-row mask for exhaust gas of the present invention is exhaled through the nostrils or through the mouth, the cavity of the mask is always in a negative pressure state, let alone in a negative pressure state when inhaling, so there is no atomizing glasses at any time. question.

6. Masks need to be changed frequently no matter what the purpose is, but using this invention is an option that is both comfortable to wear and extremely low-cost. The filter cloth of the mask cannot be reused because of the quality of air filtration. Although a cloth-like mask is material saving, it is uncomfortable to wear; the mask with an exhaust valve on the market has not yet seen that the exhaust can be disassembled and reused, because its exhaust valve is very simple and fixedly generated in the mask filter. On the cloth, it is of little value to remove it. The value of the waste gas single-row mask of the present invention to promote the repeated use of the valve device is that: an integral control mask inner cavity composed of accessories such as the single-row valve in front of the mouth, the single-row valve in front of the nose, the front tube, the left nasal tube, the right nasal tube and the like is in the inner cavity of the mask. The device that always maintains negative pressure is more complicated. As long as this mechanism is flexibly installed on the filter cloth of the mask, the purpose of wearing it comfortably and changing the filter cloth of the mask at will is achieved.
