Technical Field

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

Background

People can feel suffocated when wearing the mask daily.

Why is the mask feel suffocated? The cloth-like mask only has a little area in the front of the mouth and the nose to play the role of ventilation, most of the rest area is tightly attached to the face to play the role of ventilation, and the speed of air inlet and outlet is slow, so that suffocation is realized; whether the mask with the cavity in front of the mouth is provided with the exhaust valve or not, the exhaust gas exhaled from the mouth always circulates in the cavity, and the content rate of the exhaust gas exhaled by people is only 16%, which is equivalent to that people are in an insufficient oxygen supply state for a long time, so that suffocation is realized. In summary, all masks on the market today either have a slow air supply rate or insufficient oxygen supply, and feel suffocating anyway.

Besides holding breath, the mask has many problems: poor heat dissipation and burning sensation on the face; the glasses are easy to atomize due to air leakage at two sides of the nose bridge; the filter cloth can not be cleaned, and the single use cost is high, etc.

I know that people have a history of thousands of years of using masks, and the improvement of wearing comfort of the masks is not a common difficulty.

What is there a solution to the above problem? I made the following attempt.

Disclosure of Invention

Aiming at the defects of the prior art, the invention provides a waste gas single-row mask, which solves the problems in the background art.

It is known that when a jet of air enters through a narrow duct, according to the venturi (venturi i) principle, the jet of air creates a negative pressure around the inlet of the duct and carries a certain amount of air with open edges into the duct.

In order to solve the problems, the invention is realized by the following technical scheme:

a single-row waste gas mask comprises mask filter cloth, a right nasal tube with a right nasal orifice, a mouth support, a front mouth tube with a front mouth orifice, a front mouth single-row valve, a front nose single-row valve, a left nasal tube with a left nasal orifice, a nose support and an elastic mask belt, wherein the front mouth tube and the front mouth single-row valve are arranged at the middle lower part of the mask filter cloth, the front nose single-row valve, the left nasal tube and the right nasal tube are arranged at the middle upper part of the mask filter cloth, the mouth support is arranged at the outer side of the front mouth tube, the front mouth tube is arranged at the inner side of the front mouth single-row valve, the left nasal tube and the right nasal tube are arranged at the inner side of the front nose single-row valve, the front mouth single-row valve is in adaptive connection with the front mouth tube, the front nose single-row valve is in adaptive connection with the left nasal tube and the right nasal tube, certain gaps are formed between the nose support and the left nasal tube and the right nasal tube, and when a wearer exhales, the air around the left nasal tube and the right, The right nasal tube is discharged through a front single-discharge valve through nose; when a wearer inhales air by using the nostrils, because the front single-row valve of the nose is closed, the waste gas in the left nasal tube and the right nasal tube is in a state without passage, and the wearer can only inhale fresh air coming in from gaps among the nasal stent, the left nasal tube orifice and the right nasal tube orifice; a certain gap is formed between the mouth support and the mouth front pipe orifice, and when a wearer exhales with the mouth, air around the mouth front pipe orifice is sucked into the mouth front pipe and then is discharged through the mouth front single-row valve; when a wearer inhales with the mouth, because the front single-row valve of the mouth is closed, the waste gas in the front tube of the mouth is in a state without a passage, the wearer can only inhale fresh air coming in a gap between the mouth bracket and the front tube opening of the mouth, and therefore the high-efficiency replacement effect that the air inlet is fresh and easy and the waste gas is discharged by 100% is achieved.

Optionally, the shape of the mouth front orifice, the left nasal orifice and the right nasal orifice is circular or oval or lip-shaped or square.

Optionally, the left nasal cannula and the right nasal cannula are integrally formed, or the left nasal cannula and the right nasal cannula are designed into the same branch tube opposite to the left nostril and the right nostril of the wearer.

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

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

Further, the left nasal tube and the right nasal tube are designed as venturi tubes with certain gaps from the nose of the wearer.

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

Compared with the existing one-piece cloth mask or the mask with a cavity in front of the mouth in the market, the single-row waste gas mask has the following advantages:

firstly, no matter what way to exhaust, the waste gas can not be diffused in the cavity of the mask filter cloth all the time. The existing masks in the market can be visually classified into two types: although a cavity in the front of the mouth and the nose is small, the area of the filtering cloth of the mask which actually plays a role in filtering is small, and air inlet and outlet are not smooth; there are many kinds of mask with large cavity in front of nose and mouth, and some have exhaust valve or independent filter box. In a word, cavities are arranged in all masks in the market, after people exhale, waste gas with the oxygen content of only 16% always occupies the cavity in front of the mouth and nose, and when people inhale the mask next time, the waste gas in the cavity is inhaled first. The oxygen content in the atmosphere is 21 percent, and the waste gas with approximately less than one fourth of the oxygen content circulates all the time when breathing, so people always feel suffocated after wearing the mask. According to the structure and the Venturi principle, no matter people use nostrils, mouths or noses and mouths to exhale waste gas at the same time, air around the mouth of the left nasal tube and the mouth of the right nasal tube is always inhaled into the left nasal tube and the right nasal tube and then is exhausted through the nose front single-exhaust valve; the air around the mouth of the mouth in front of the mouth is always sucked into the front mouth pipe and then discharged through the front mouth single-row valve, so that the waste gas can not be diffused into the cavity of the mask filter cloth all the time.

Secondly, whatever the way of inhalation, all inhaled is the filtered fresh air. The way people inhale varies widely, and besides the habit of inhaling, generally: when the patient is relaxed, the nostril is adopted for inhaling; also, the mouth is adopted to suck when the physical strength is active; when the heavy body is active, the nose and the mouth can breathe simultaneously. No matter what the breathing condition of the mask with a large cavity in front of the mouth is, the waste gas with the oxygen content of only 16 percent always occupies the cavity in front of the mouth and the nose, the waste gas in the cavity is firstly sucked, and the circulation is carried out. The waste gas of the single-row mask can not be diffused in the cavity of the filter cloth of the mask all the time. When people inhale air through the nostrils, although a very small amount of waste gas is hidden in the left nasal tube and the right nasal tube, the single-row valve in front of the nose is in a closed state at the moment, the waste gas cannot come out, and all inhaled air in the nostrils is filtered and fresh air with the oxygen content of 21 percent enters gaps among the nasal stent, the left nasal tube orifice and the right nasal tube orifice; when people inhale with the mouth, although a very small amount of waste gas is stored in the front tube of the mouth, the front single-row valve of the mouth is in a closed state, the waste gas is not discharged, and all the fresh air which enters the gap between the mouth support and the front tube mouth of the mouth, is filtered and contains 21 percent of oxygen is inhaled in the mouth.

And thirdly, the problem of difficult breathing can not be felt at any time. The area of a cloth-like mask which actually plays a role in filtering is too small, airflow passes through the mask slowly, and the mask feels difficult to breathe after being worn for a long time; the mask with a large cavity in front of the mouth can store waste gas, and the waste gas with extremely low oxygen content rate can always circulate in the cavity, so that the mask can feel difficult to breathe after being worn for a long time. The single-row exhaust gas mask is provided with the front mouth pipe, the left nasal tube and the right nasal tube which support the middle part of the mask filter cloth, so that the actual filtering area is greatly increased, and fresh air is fully supplied during air suction; when the respirator is used for breathing out, the waste gas is not diffused in the cavity, and when the respirator is used in the whole cavity, fresh air with the oxygen content of 21% is filled in the cavity, so that the respirator is comfortable and easy to wear for a long time.

Fourthly, the face does not have burning sensation at any time. At present, cavities are formed in all masks in the market before mouths and noses, when people exhale waste gas, positive pressure states are immediately presented in the cavities, and the face can feel hot as long as the face leaks air due to the fact that the temperature of the gas exhaled from a human body is higher. The single-row mask for waste gas is always in a negative pressure state in the cavity of the mask no matter the mask is used for breathing out by nostrils or mouth, and the phenomenon that waste gas at higher temperature runs everywhere is avoided because no waste gas is diffused in the cavity.

Fifthly, the glasses cannot be atomized at any time. Most of the current knowledge molecules wear glasses, and the medical industry has more people wearing glasses and has high probability of needing to wear a mask for work. The protruding face in face of people's the bridge of the nose, the gauze mask edge is hardly sealed these both sides, and the possibility that both sides leak waste gas is very big about the bridge of the nose to the steam that leaks out directly blows to glasses, blurs at once on the lens, seriously influences people's eyesight. The single-row exhaust mask always presents a negative pressure state in the cavity of the mask no matter the mask is used for breathing out by a nostril or a mouth, and the problem of atomizing glasses does not exist at any time when the mask is used for breathing in, not to mention the negative pressure state.

Sixth, whatever the use, the mask needs to be changed frequently, but the adoption of the invention is an option which is comfortable to wear and extremely low in cost. The filter cloth of the mask cannot be reused because of the requirement of air filtering quality. A cloth-like mask is not comfortable to wear although the material is saved; the mask with the exhaust valve in the market does not have the exhaust valve which is detached and reused independently at present, because the exhaust valve is very simple and is fixedly formed on the filter cloth of the mask, and the exhaust valve has no value when being detached. The valve device is advocated to be reused by the waste gas single-row mask, and the value is as follows: the device for controlling the negative pressure in the mask cavity permanently, which is formed by the front single-row valve of the mouth, the front single-row valve of the nose, the front tube of the mouth, the left nasal tube, the right nasal tube and other accessories, is complex, and the aim of wearing comfort and replacing the mask filter cloth at will can be realized only by flexibly installing the mechanism on the mask filter cloth.

Fig. 1 shows a schematic structure of the exhaust gas single row mask of the present invention.

Referring to fig. 1, the single exhaust mask comprises a mask filter cloth 1, a right nasal tube 3 with a right nasal tube orifice 2, a mouth support 4, a front mouth tube 5 with a front mouth tube orifice 6, a front mouth single-row valve 7, a front nose single-row valve 8, a left nasal tube 9 with a left nasal tube orifice 10, a nose support 11 and an elastic mask belt 12, wherein the front mouth tube 5 and the front mouth single-row valve 7 are arranged at the middle lower part of the mask filter cloth 1, the front nose single-row valve 8, the left nasal tube 9 and the right nasal tube 3 are arranged at the middle upper part of the mask filter cloth 1, the front mouth tube 5 is arranged at the inner side of the front mouth single-row valve 7, the left nasal tube 9 and the right nasal tube 3 are arranged at the inner side of the front nose single-row valve 8, the left nasal tube 9 and the right nasal tube 3 are arranged at the inner side of the front mouth single-row valve 8, the mouth support 4 is arranged at the outer side of the front mouth tube orifice 6, the front mouth single-row valve 7 is in fit connection with the front mouth tube 5, the front nose single-row valve, when a wearer exhales through the nostrils, air around the left nasal orifice 10 and the right nasal orifice 2 is sucked into the left nasal tube 9 and the right nasal tube 3 and then is exhausted through the nose front single-row valve 8; when a wearer inhales with the nostrils, because the front single-row valve 8 of the nose is closed, the waste gas in the left nasal tube 9 and the right nasal tube 3 is in a state without passage, and the wearer can only inhale fresh air coming from gaps among the nasal stent 11, the left nasal tube mouth 10 and the right nasal tube mouth 2;

a certain gap is formed between the mouth support 4 and the mouth front pipe orifice 6, and when a wearer exhales with the mouth, air around the mouth front pipe orifice 6 is sucked into the mouth front pipe 5 and then is discharged through the mouth front single-row valve 7; when the wearer inhales with the mouth, because the front single-row valve 7 is closed, the waste air in the front mouth pipe 5 is in a non-passage state, and the wearer can only inhale the fresh air coming in from the gap between the mouth support 4 and the front mouth nozzle 6.

The inner side of the front single-row valve 7 is provided with a front mouth pipe 5, and the inner side of the front single-row valve 8 is provided with a left nasal pipe 9 and a right nasal pipe 3. The shapes of the mouth front orifice 6, the left nose orifice 10 and the right nose orifice 2 are round or oval or lip-shaped or square. The left nasal cannula 9 and the right nasal cannula 3 are integrally formed, or the left nasal cannula 9 and the right nasal cannula 3 are designed into the same branch tube opposite to the left and right nostrils of the wearer. The left nasal cannula 9, the right nasal cannula 3 and the anterior mouth tube 5 are an integral assembly, or an integrally formed member. The nasal stent 11 controls the width of the gap between the left nasal orifice 10, the right nasal orifice 2 and the nostrils.

The anterior mouth tube 5 is designed as a venturi tube with a certain gap from the lips of the wearer, and the left nasal tube 9 and the right nasal tube 3 are designed as venturi tubes with a certain gap from the nose of the wearer.

The front single-row valve 7 and the front single-row valve 8 are one-way exhaust valves, and the front single-row valve 7 and the front single-row valve 8 are partially exposed outside the mask filter cloth 1.

The positions of the nose front single-row valves 8 arranged on the left nasal tube 9 and the right nasal tube 3 and the positions of the mouth front single-row valves 7 arranged on the mouth front tube 5 are specifically determined according to the distance between the mask filter cloth 1 and the lips; the nose front single-row valve 8, the mouth front single-row valve 7, the mouth front pipe 5, the left nose pipe 9 and the right nose pipe 3 which are arranged on the mask filter cloth 1 can be produced by a single assembly and are used for adapting to the corresponding type of mask filter cloth.

The front single-row valve 7 and the front mouth pipe 5 are sleeved and then flexibly structured at the middle lower part of the mask filter cloth 1. The front single-row valve 8 is sleeved with the left nasal tube 9 and the right nasal tube 3 and then flexibly arranged at the middle upper part of the mask filter cloth 1. The proper lengths of the front mouth tube 5, the left nasal tube 9 and the right nasal tube 3 are designed according to the distance between the back mouth and the nose of the mask and the middle part of the mask filter cloth 1 when a person wears the mask. The nasal stent 11 controls the width of the gap between the left nasal orifice 10, the right nasal orifice 2 and the nostrils. The mouth support 4 controls the width of the gap between the mouth front orifice 6 and the mouth skin. The elastic mask band 12 can be adjusted in length according to individual differences of people.

When the wearer exhales with the nares: when the bigger air flow in the nostril rushes into the left nasal tube 9 and the right nasal tube 3 to open the nasal front single-row valve 8, the air around the left nasal tube opening 10 and the right nasal tube opening 2 is also brought into the left nasal tube 9 and the right nasal tube 3 and then discharged through the nasal front single-row valve 8.

When the wearer exhales with the mouth: the air around the mouth orifice 10 is carried into the mouth front pipe 5 and discharged through the nose front single-row valve 7 at the same time when the mouth front pipe 5 is opened by the larger air flow in the mouth.

When the wearer inhales air with the nostrils: at this time, the anterior nasal single-row valve 8 is closed, so that very little exhaust gas in the left nasal tube 9 and the right nasal tube 3 can not be sucked, air in the nostrils can only enter from gaps among the nostrils, the left nasal tube orifice 10 and the right nasal tube orifice 2, and all the air entering is fresh air containing oxygen of up to 21 percent.

When the wearer inhales air with the mouth: at this point, the front mouth single-row valve 7 is closed, little exhaust gas in the front mouth pipe 5 can not be sucked, and the air intake of the mouth can only enter from the gap between the mouth skin and the front mouth nozzle 6, and the entering air is all fresh air containing up to 21 percent of oxygen.

It goes without saying that the single exhaust mask of the present invention may be changed or modified in many ways, and is not limited to the specific configurations of the above embodiments, such as various changes in the shapes, sizes and mounting positions of the anterior mouth tube, the left nasal tube and the right nasal tube. In summary, the scope of the present invention for creating an exhaust single row exhaust mask also includes such exchanges, substitutions and modifications as would be apparent to one of ordinary skill in the art.
