Description

Smoking protective mask and its valve structure

The present invention relates to a protective mask and its valve structure, in particular to a protective mask and its valve structure with the function of absorbing tea, coffee or beverages, or nasogastric tube feeding.

In recent years, the rapid development of industry and cities, various factories, coal-fired power plants, and a large number of steam and locomotive exhaust emissions have caused serious air pollution, dust and haze (fine suspended particles PM2.5), pollen, and dust in the environment. , Entering the human body through the respiratory tract can cause various diseases such as allergies, asthma or colds, sneezing, runny nose, etc., causing a decline in human immunity and seriously affecting human health.

In order to prevent air pollution and prevent the spread of germs and diseases, wearing a mask is the most convenient and cost-effective method. However, there are still many inconveniences when wearing masks. For example, drinking water is a basic human physiological need (at least 2,000 cc or eight to ten glasses of water per day) or people often use straws to inhale drinks. For people who wear masks for a long time, many precautions and steps need to be taken during the process of inhaling tea, coffee, drinks, etc., such as removing the mask and putting it on again or directly replacing it, it may be exposed to infection if it is careless. Wearing and taking off masks frequently can also increase the chance of infection.

In addition, Taiwan has 200,000 patients who use nasogastric tube feeding every year. Most of them walk around in medical institutions without wearing a mask or without a suitable mask. They usually have low immunity and they need to be able to wear it. A mask that can be protected in the event of feeding.

In addition, for N95 masks, in order to reduce the exhalation resistance and reduce the stuffiness inside the mask, most of them will be equipped with an exhalation valve device. The exhalation valve is a one-way exhalation valve, which allows air to be exhaled from the inside of the mask during exhalation, and discharged out of the mask through the exhalation valve. Although this type of mask provides high protection and wearing comfort, it does not provide a suction function and a good protective effect for those who need to drink tea, coffee or beverages.

In view of this, one of the objectives of the present invention is to provide a smoking protective mask and its valve structure, which is convenient for users to ingest tea, coffee or beverages, while the mask continues to effectively filter external dust and germs to maintain good filtration efficiency .

The second object of the present invention is to provide a smoking protective mask and its valve structure.

In this way, the user can conveniently inhale tea, coffee or beverages, and the mask continues to effectively filter external dust and germs while inhaling, so as to maintain a good filtering performance.

Please refer to Figures 9 and 10, which are a preferred embodiment of the present invention. The difference between this embodiment and the previous embodiment is that the mask body (6) is an N95 mask body. In this way, the user can conveniently inhale tea, coffee or beverages, and the mask continues to effectively filter external dust and germs while inhaling, so as to maintain a good filtering performance.

Please refer to FIG. 11, which is a preferred embodiment of the present invention. The difference between this embodiment and the previous embodiment is that it further includes an elastic and expandable diaphragm (15) corresponding to the perforation (40) and connected to the valve Seat (10) is set. Thereby, before the present invention is used, the elastic expandable and closable diaphragm (15) is in a closed state. When the straw passes through the perforation (40), the elastic expandable and closable diaphragm (15) can be expanded to reduce the amount of straw and The pores between the perforations (40) are produced, which can prevent the inhalation of dirty air and germs during the smoking process. The material of the elastic openable and closable diaphragm (15) can be silicone or rubber.

Please refer to FIG. 12, which is a preferred embodiment of the present invention. The difference between this embodiment and the previous embodiment is that it can further include a connecting strip (51) that connects the valve plug (50) and the valve cover (30). ). Thereby, when the valve plug (30) is removed from the perforation (40), the valve plug (50) does not need to be stored separately, and the valve plug (50) can be prevented from falling or losing.

Please refer to Fig. 13, a smoking protective mask provided by the present invention includes: a mask body (7), a hole plug (703), an exhalation valve (8), and a strap set (201), as described below:

The mask body (7) can be a C-shaped structure or a clam-shaped structure. It is even a general flat mask structure. The mask body (7) can be provided with an opening (701) in the left half (or right half), and the opening (701) can be circular, triangular, rectangular or elliptical.

The hole plug (703) can be inserted into the hole (701) for sealing. Before the present invention is used, the hole plug (703) is plugged in the opening (701) in a sealed state; when it is to be used or sucked, the hole plug (703) needs to be removed first. The hole plug (703) can be made of rubber, silicone, plastic, etc., and it can be round, triangular, rectangular, or elliptical, or shaped to match the shape of the opening (701).

The exhalation valve (8), which is installed on the mask body (7), can be installed on the left half or/and the right half of the mask body (7), and it is a one-way exhalation valve that allows exhalation When the air is exhaled from the inside of the mask, it is discharged out of the mask through the exhalation valve (8).

The strap set (201) is connected to the mask body (7). The strap set (201) includes two straps (203), which are respectively connected to the left and right sides of the mask body (7). Wherein, the strap (203) can be an ear strap, a head strap or a strap, and it can be elastic or inelastic.

After the inhalation is completed, remove the straw (3) and then plug the hole plug (703) back into the opening (701) to seal. In addition, patients who do not eat normally can put the nasogastric tube through the opening (701) into the stomach, and wear a mask to avoid infection or inhalation of droplets in the air.

Among them, exhaling through the exhalation valve (8) can reduce the exhalation impedance and reduce the stuffiness inside the mask. Therefore, the present invention can meet the needs of smoking and protection, and is comfortable to wear, easy to breathe, safe and hygienic in use, and has an extremely wide range of applications.

Please refer to FIG. 15, which is a preferred embodiment of the present invention. The difference between this embodiment and the previous embodiment is that it further includes an elastic stretchable and closable membrane (15) corresponding to the opening (701) and connected to the mask Body (7) settings. The material of the elastic openable and closable diaphragm (15) can be silicone or rubber. Thereby, before the present invention is used, the elastic expandable and closable diaphragm (15) is in a closed state. When the straw is inserted into the opening (701), the elastic expandable and closable diaphragm (15) can be expanded or opened to reduce the amount of straws. The pores between the openings (701) and the openings (701) are created to avoid inhaling dirty air or germs during the smoking process. Therefore, the smoking of the present invention also has functions such as protective effects.

The present invention is suitable for any type of masks, such as flat masks, activated carbon masks, three-dimensional or dust-proof masks, such as N95 masks, bowl-shaped masks, mussel-shaped masks, C-shaped masks, duckbill masks, etc., as well as anti-haze series masks, etc. .

In summary, compared with the prior art, the present invention has the following effects: it is convenient for users to inhale tea, coffee or beverages, and the mask continues to effectively filter external dust and germs while inhaling, so as to maintain good filtration efficiency. In addition, patients who do not eat well can pass the nasogastric tube through the perforation of the valve structure or the opening of the mask body and then put it into the stomach. Wear a mask to avoid infection or inhalation of droplets in the air. The use is safe and hygienic, and the application range is extremely wide.

In addition, the present invention also has other effects: it is suitable for indoor and outdoor use in air pollution environments such as anti-bacteria, dust and haze, and can still be worn in areas with high haze or air pollution.
