Description

Inhalation and exhalation masks

A mask, especially a mask having a mask body and an exhalation component, which can isolate and separate the inhaled gas and the exhaled gas from each other.

With the development of modern civilization, the degree of industrialization of society is getting higher and higher, various manufacturing industries are booming, and the number of vehicles on the road is increasing, which has led to economic development. In the process of social progress, many pollution factors have also been produced. Quality creates many negative effects, such as fine suspended particulates (PM2.5). Fine suspended particulates come from a wide range of sources. For example, thermal power plants that use mass transportation, ride on motorcycles, burn incense to temples, and burn coal and oil as power generation tools all produce large amounts of fine suspended particulates. As a result, the proportion of fine suspended particles in the air is gradually increasing, the air quality is getting worse and worse, and even the terms "haze" and "haze" are used to describe the harmful situation of fine suspended particles. In addition to the above-mentioned human activities, in addition to the production of fine suspended particles, other pollution factors that are harmful to the environment or the human body, such as sulfur dioxide, nitrogen oxides, volatile organic compounds, etc., are also produced. Substances can cause acid rain, pollute the air, and greatly reduce air quality.

In order to cope with the increasing air pollution, many people wear masks one by one when they go out to avoid being harmed by poor air quality. The masks commonly used today can cover the nose and mouth, and the masks are filled with filter substrates, such as activated carbon, filters, etc., that can attach pollution factors, which can filter the air and avoid inhaling these pollution factors . These masks cover the nose and mouth at the same time, so that when exhaling, the exhaled air cannot easily escape from the mask, leaving a lot of space between the mask and the nose and mouth Exhaled air, while inhaling, in addition to the air sucked in from the outside can be filtered through the filter substrate, the air remaining between the mask and the nose and mouth will be sucked back again by the nose and nose, it is still not good for human health positive effect.

When you are exercising, if you want to avoid inhaling a lot of pollution factors and wear a mask, the frequency of cardiopulmonary exercise will be higher than usual, which will increase the inspiratory volume and exhale a lot of hot air. The space between the mask and the mouth will inhale the exhaled hot air when inhaling, leaving a large amount of carbon dioxide and hot gas between the mask and the mouth. Repeated and frequent inhalation will easily cause hypoxia and physical failure.

In addition, because the mask inhalation and exhalation of the general mask are in the space between the mask and the mouth, the exhaled gas will not only be discharged from the filter layer of the mask itself, but also escape from the edge of the mask. Glasses, the exhaled gas easily adheres to the glasses and fogs the glasses, causing inconvenience.

In order to separate the inhaled air from the exhaled air, this creation proposes a mask that separates the inhaled air from the exhaled air, to avoid mixing the inhaled air with the exhaled air and re-exhaling the exhaled air again.

In order to achieve the above purpose, a mask for separating inhalation and exhalation is included in the present invention. An exhalation component includes: a cover having an opening at the mouth, at least one first fixing element and two first fasteners. The mouth opening is formed at the rear end of the casing, the first fixing element is disposed on the outer surface of the casing, and the two first fasteners are respectively disposed at symmetrical ends of the outer surface of the casing; a hanging strap A buckle is provided at each end of the buckle, and the buckle is used to tie the strap to the first fasteners of the cover; A first duct is provided at the lower portion of the cover, and has an upper opening and a lower opening; and a mask body connected to the exhalation component and including an air contact surface and an opposite filtering surface There is at least one second fixing element on the filtering surface, and the second fixing element is connected to the first fixing element to fix the exhalation component and the mask body to each other.

The first fixing element and the second fixing element may be a suede surface and a hook surface of a devil felt, respectively, and can be adhered to each other to connect the exhalation component and the mask body. The exhalation component can cover the mouth, so that the air in contact with the mouth is separated from the nose. When inhaling through the nose, the clean air filtered by the mask body can be sucked. When exhaling, the exhaled exhaust gas can pass through the first duct It is introduced into the outside air without being directly inhaled by the nostrils, and the effect of inhaling and exhaling gas is separated.

The wall of the other opening of the first duct can be connected to a detachable second duct. The second duct has a filter sheet, which can be a filter substrate such as activated carbon or a filter screen. The moisture and impurities in the exhaled air are filtered, and the filter sheet can be embedded in a groove in the second conduit.

The first catheter can be further provided with a straw opening. For example, when performing cycling or running, the straw can be inserted into the straw opening, and the drinking water can be easily accessed without removing the mask; and In a general state, a straw cap can be used to tightly close the straw opening without allowing dust to pollute the straw opening or enter the respiratory tract through the straw opening.

In addition, if hypoxia occurs during the exercise, the first conduit can be further connected to the oxygen conduit, and the oxygen can directly absorb the oxygen in the oxygen cylinder / oxygen cylinder without removing the mask.

The function that the first catheter can lead down the exhaled gas allows the user to keep the glasses clean when wearing glasses, and will not fog the glasses due to the exhaled gas contacting the glasses.
