Description

Novel mask

Technical Field

The utility model relates to the field of medical health technology and daily protection, specifically a can replace gauze mask of filter core.

Background

With the continuous development of industry, the environment is influenced to a certain extent, the air quality of cities is reduced year by year, especially in areas with more developed industrialization and dense factories and cities with high population density, the air pollution is serious, and the life quality of urban residents is seriously influenced. An increase in airborne pollutants, such as smoke, carrying high levels of Particulate Matter (PM), including heavy metals, toxic chemicals and compounds, bacteria and viruses, and the like, typically from industrial activities, burning coal, automobile exhaust and other sources, are airborne through the respiratory tract into the body and even deep into the lungs, penetrating the alveoli into the blood circulation system, and if they are not filtered from the breath, can cause permanent DNA mutations, heart attacks, respiratory diseases, cancer and premature death, seriously threatening human health.

The mask is a hygienic product, but as people pay more and more attention to healthy traveling, the mask will become a necessity for life of people in the future. Generally, the mask is worn at the mouth and nose part for filtering air entering the mouth and nose and blocking harmful gas, smell, spray and the like from entering and exiting the mouth and nose of a wearer, and is an effective tool for preventing harmful substances from being transmitted through a respiratory tract. The mask has a certain filtering function on air entering the lung, has a very good effect when being worn when respiratory infectious diseases are prevalent or work is carried out in an environment polluted by dust and the like, can effectively protect a wearer, and avoids infection and harmful substance inhalation.

The existing mask is mostly made of materials such as gauze or paper, the raw materials are simple, the mask can only block granular objects generally, and the mask cannot prevent the pollutants with small molecular weight from entering the mouth and nose of a user, so that the filtering effect is general. The gauze mask has poor close fit with the face of a person, a plurality of fine particles which are extremely harmful to the human body enter respiratory tracts through gaps between the gauze mask and the face and reach the lung, the filter material of the gauze mask is usually a plurality of mechanical fabrics, the filter material has high dust blocking efficiency, the only method is to increase the thickness, and the negative effect of increasing the thickness is to enable the user to feel that the respiratory resistance is high and the user feels uncomfortable.

Most of masks on the market are disposable masks which cannot be cleaned, the strength and the durability ratio of the masks are poor, the masks are easily torn, the service time is short, and resource waste is easily caused. The production of a mask that can be reused and that can effectively filter air is therefore highly desirable to the user.

Disclosure of Invention

The utility model discloses at first, made comprehensive investigation to current gauze mask, the discovery has following defect and not enough at least to current gauze mask:

1-the type of the mask on the market is too single at present, the material of the mask can not be fully utilized, and the problems of insufficient sources of goods and the like can easily occur. The disposable mask on the market is mostly made of materials such as gauze or paper, the raw materials are simpler, and the filtering effect is more common. Or some masks achieve a more ideal filtering effect by increasing the thickness, which causes great breathing resistance of a wearer and increases the burden;

2, most masks on the market are disposable masks, cannot be cleaned, have poor strength and durability ratio, are easy to tear, have short service time and are easy to cause resource waste;

3-the disposable mask on the market is not tightly attached to the face of a wearer, so that the problem of insufficient sealing performance exists, particularly for some myopia people, hot air is discharged from the mask when the mask is worn, the lenses are blurred, and the visual field is affected;

4-most reusable mask on the market is composed of face-attached silica gel and a plastic cover with a replaceable filter element at the front end, the multifunctional integrated filter element has large air resistance, is easy to cause unsmooth breathing and is not suitable for being worn for a long time, and because various additives are required to be added during the manufacture of the plastic cover, the problems of peculiar smell and environmental pollution when the mask is not used exist.

In order to at least solve one of the defects of the prior mask, the utility model aims to provide a novel mask, the filter element of which can be replaced, and the mask can be repeatedly used, thus saving the production cost; the second purpose of the utility model is to provide a novel mask which has good sealing performance; the third purpose of the utility model is to provide a novel mask, the strip of which is adjustable, which enables the mask to better fit the wearers of different face shapes.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a novel mask, includes silica gel pad, silica gel cover, filter core, the silica gel cover is fixed on the silica gel pad, the silica gel cover is equipped with the filter core opening, the filter core passes through place in the silica gel cover in filter core opening detachably.
