Description

Reusable protective mask with rainproof and anti-wind-choking functions

Technical Field

The invention relates to the technical field of protective masks, in particular to a reusable protective mask with rain-proof and wind-choking-proof functions.

Background

The common masks in the market at present comprise a plane mask and a three-dimensional dustproof mask. The commonly used disposable mask causes material waste on one hand, and on the other hand, the mask becomes garbage after being used, thereby increasing environmental pollution. Some masks can be used for multiple times, and the masks are usually cotton cloth masks which can be used after being repeatedly cleaned, but do not have the filtering effects of preventing viruses and PM2.5 pollution. There are some anti-virus and anti-PM 2.5 polluted masks, such as N95 mask, the whole mask is an integral layered structure, when in use, the mask loses the protection function after the mouth and nose are wet and have large peculiar smell, and the materials of the face and the surrounding position are not damaged, however, the mask can only be replaced due to losing the filtering and protecting functions, which causes unnecessary waste. At present, some masks capable of replacing the filtering part can be used repeatedly, filtering materials are saved, unnecessary waste is reduced, but the mask part is not attractive due to the fact that plastic materials are not used, ventilation of the mouth and the nose is poor, the temperature is high, a user feels uncomfortable, the mask part is long in service time, the mask part is wet and cannot work, and filter cotton needs to be replaced in time. Moreover, all the masks have no rainproof function, so that when the mask is taken out in rainy days, the mask is worn, and once the rain mask is wetted, the mask loses the protective effect and cannot be used continuously, thereby causing great waste. In addition, when the existing soft cotton mask is worn, wind and splashes carried in the wind can blow to the respiratory system of the face of a human body through the mask, wind choking is easily caused, and meanwhile, the infection of the splashes is caused.

Disclosure of Invention

The invention aims to solve the problems that the existing protective mask is short in service life, difficult to breathe due to wind choking when wind is strong, and incapable of realizing a rainproof function, and further provides a reusable protective mask with rainproof and anti-wind choking functions.

The technical scheme adopted by the invention for solving the technical problems is as follows:

a reusable protective mask with rain-proof and wind-choke-preventing functions comprises a face mask, a hanging belt component, a breather valve shell, a valve cover and two trachea components, wherein the hanging belt component is symmetrically and fixedly connected to the side edge of the face mask, the inner side end of the breather valve shell is embedded and fixed in the middle of the front of the face mask, a filter disc is clamped on the inner side end face of the breather valve shell, the valve cover is clamped on the outer side end face of the breather valve shell, and the left side and the right side of the breather valve shell are respectively and symmetrically connected with one trachea component.

Compared with the prior art, the invention has the following beneficial effects:

the mask of the protective mask can be repeatedly used, when the filter sheet reaches the service life, only the filter sheet needs to be replaced, and the whole mask does not need to be replaced again. Meanwhile, the protective mask also has the functions of preventing rain and wind choking. The air current circulates along the air pipe assembly, is not influenced by the wind direction, and effectively prevents from choking wind and splashing. The invention is wholly made of environment-friendly materials, reduces environmental pollution, prolongs the service life, can be used in rainy days and can play a good role in protection. The invention can be used for the protection of respiratory systems in medical treatment, environmental protection, industry and daily life.

Principle of operation

When the filter 6 needs to be replaced, firstly, the valve cover 4 is opened, the press ring 7 is taken out from the breather valve housing 3, the filter 6 which needs to be replaced is taken out, a new filter 6 is put in, then the press ring 7 is bent to enable the press ring 7 to be put in a positioning ring of the breather valve housing 3, the press ring 7 is loosened, and the press ring 7 presses the filter 6 in the breather valve housing 3 to play a sealing role. Finally, the valve cover 4 is covered on the valve body of the breather valve shell 3, thereby completing the replacement work of the filter 6.

The structural mode of trachea subassembly 5 has the function of preventing chocking wind, when outside air flows around face guard 1 promptly, the air in the breather valve case 3 can only be discharged from the last lower limb of the vertical trachea 5-2 of both sides, and can not chock wind, enter into inside the breather valve case 3 in the opposite direction, thereby make the moist moisture of the gaseous of exhalation discharge along the exhaust gas stream all the time, can not stop in breather valve case 3, thereby keep the dry and comfortable of breather valve case 3, the inside temperature of gauze mask also can only be discharged along a discharge direction all the time, thereby reduce the inside temperature of face guard 1, keep the temperature of nose department not high, and people's travelling comfort. The most of the moisture of the inboard human body exhalation of face guard 1 all discharges through trachea subassembly 5, and a small amount of residual vapor that floats on face guard 1 after long-time the use can be got rid of through the mode of cleaning with clean paper handkerchief, and the clearance is convenient, does not have the peculiar smell to persist.
