Description

A kind of anti-smog mask

technical field

The utility model relates to personal protective equipment, in particular to an anti-haze mask.

Background technique

In recent years, with the sharp increase of the Air Pollution Index, smoggy weather has become more and more frequent and the number of PM2.5 in the air has repeatedly broken records. PM2.5 particles in the smog weather can cause discomfort in the lungs of the human body. PM2.5 enters the respiratory tract, stimulates and destroys the tracheal mucous membrane, resulting in a decline in the function of the mucous membrane of the organ to kill viruses and bacteria and resist them from entering the lung tissue. The tracheal mucous membrane The detoxification function of the human body is reduced, and what's more, it will cause respiratory diseases such as lung cancer. Usually people will wear masks for dust protection to stop the dust in the air. However, general masks are only suitable for preventing large-diameter dust particles, which are not enough to effectively prevent PM2.5 particles in the air. This is because ordinary masks prevent dust from being inhaled into the human body by changing the porosity of the veil of the mask. If the porosity of the veil is reduced to prevent PM2.5 particles, this can reduce the passage of tiny particles, but it is also relatively large The passage of air is reduced, making it difficult for the human body to breathe. In addition, when wearing a mask to exhale in winter, water vapor will overflow from the top of the mask, making the vision of the user wearing glasses blurred.

In addition, most of the existing anti-haze masks on the market filter tiny particles by direct blocking, or block particles from passing through the filter layer by activated carbon adsorption, so as to achieve the purpose of protection. Most of the existing anti-smog masks use non-woven 3-4 composite layers to achieve the purpose of filtering in terms of material design, without effective management of the exhaled airflow, and the comfort of breathing when wearing the mask is not considered.

Moreover, the anti-smog masks on the existing market are generally 3-4 layers of non-woven fabrics directly compounded together, and the middle layer directly uses melt-blown cloth with a filtering effect as the filter layer. Large, difficult to breathe, not suitable for people with asthma and respiratory diseases.

Utility model content

The purpose of this utility model is to provide a kind of anti-haze mouth mask.

According to one aspect of the present invention, an anti-haze mask is provided, comprising an outer cover and a nose-piece respirator fixed inside the outer cover. The nose-piece respirator mainly includes an outwardly arched main body, and the main body cover is arranged on Above the bridge of the nose, the main body covers the nose wings along both sides until it fits the face. The shape of the upper part of the main body matches the upper part of the nose bridge and can completely fit the upper part of the nose bridge. There is a breathing hole at the opposite position, and a filter is provided outside the breathing hole. After wearing, the periphery of the main body is completely sealed with the face, and only the breathing hole passes the filter to enter and exit the air. The outer cover covers the outside of the main body and its shape matches the main body.

In some embodiments, the peripheral edge of the main body is further provided with soft wrapping, which can not only increase the comfort of wearing, but also enhance the seal between the main body and the face.

In some embodiments, the outer cover is detachably connected to the nose-piece respirator, and the outer cover after the nose-piece respirator is removed can be used as an ordinary mask.

In some embodiments, connecting buckles for connecting with the outer cover are provided on both sides of the main body.

In some embodiments, the filter is fixedly installed on the lower part of the main body through a cover, and the cover is detachably connected to the lower part of the main body. After the cover is removed, the filter can be taken out for replacement or cleaning.

In some embodiments, the lower part of the main body is provided with an accommodating cavity for accommodating the filter sheet, the breathing hole is provided at the bottom of the accommodating cavity, the cover is detachably installed at the mouth of the accommodating cavity, and the side wall of the accommodating cavity is also provided with One or more grooves, and a vent hole for gas to enter and exit is formed between the groove and the cover sheet.

In some embodiments, the two sides of the outer cover are respectively provided with ear holes for hanging the outer cover on the ears.

In some embodiments, the exterior surface of the housing has decorative patterns or text.

The anti-haze mask adopting the above technical scheme has the following technical effects:

(1) It is completely modeled on the enlarged design of the human nose shape, which solves the problem that the nose is easily pressed when wearing a general mask, and then causes uncomfortable breathing. Wearing it can achieve zero pressure on the nose, which can greatly improve comfort while wearing the mask;

(2) The material is made of food-grade soft silica gel with very softness, which can automatically adjust the fit on different users. The special outer cover and the special mask-nose respirator are two independent filter systems. The scientific combination design combines two into one, which makes the filtering effect more practical and efficient.

(3) The nose is prone to sweating when wearing an ordinary mask, and the gas exhaled from the mouth and nose will not be discharged from the body at once. The gas from ordinary masks is easy to recoil into the eyes, causing eye discomfort, especially for people who wear glasses, and the moisture is easy to blur the lenses. , resulting in a drop in sight, the anti-haze mask successfully solves the problem of the recoil of the exhaled gas after wearing an ordinary mask through the combination of a special outer cover and a nose-piece respirator, and provides a comfortable environment for the eyes;

(4) The design of the filter is small and practical, and the reduced size not only does not affect the filtering effect, but also is more environmentally friendly, convenient and affordable.

(5) Ordinary masks or nasal masks only have a single function. Some masks have poor filtering effect, and some nasal masks feel weird when worn on the street. This anti-haze mask is designed to combine the mask and nasal mask into one product. Achieve the effect of two products, stylish and beautiful appearance design, practical and dust-proof and anti-smog efficiency greatly improved.
