Special mask for preventing haze

Abstract

The invention relates to a special mask for preventing haze, and belongs to the field of protective appliances for everyday life of people. The special mask comprises a silicone face mask, filter mounting seats, PM.2.5 (Particulate Matter 2.5) filters, fixed belt fastening parts, exhalation valves, a mask body, inhalation valves and filtering layers; the mask body is arc-shaped, and the filter mounting seats are symmetrically mounted on the mask body; the exhalation valves are mounted on the cover body at the upper parts of the filter mounting seats; the inhalation valves and the PM2.5 filters with the filtering layers are mounted on the filter mounting seats; the fixed belt fastening parts are movably mounted at two sides of the mask body. According to the special mask for preventing the haze, the structure that an exhaling channel, filters and an inhaling channel are separated is adopted, and thereby, smooth airflow is ensured, a user can breathe smoothly after wearing, the mask can fit the face well, the sealing effect is great, the inhaled air can be completely filtered before entering a human body, and as a result, good haze preventing effect is realized. With the adoption of the special mask for preventing the haze, the problems of the existing haze mask that the mask cannot tightly fit the face of a people, obvious haze preventing effect is not realized, and people feels oppressed and uncomfortable after long-time wearing, can be solved.

Description

technical field [0001] The invention relates to a special anti-fog and haze mask, which belongs to the field of daily life protective articles for people. Background technique [0002] PM2.5 refers to particulate matter with a diameter less than or equal to 2.5 microns in the atmosphere, also known as particulate matter that can enter the lungs. Although PM2.5 is only a small component of the earth's atmospheric composition, it has an important impact on air quality and visibility. PM2.5 has a small particle size, is rich in a large amount of toxic and harmful substances, and has a long residence time in the atmosphere and a long transportation distance, so it has a greater impact on human health and the quality of the atmospheric environment. People should avoid outdoor activities as much as possible in the preventive measures when running into haze weather, and all wear masks for protection when going out for activities. The anti-smog mask mainly depends on whether the m...

Problems solved by technology

The anti-smog mask mainly depends on whether the mask filter can really filter PM2.5 particles and whether it fits closely with the human face, so the existing general masks have no obvious anti-smog effect; recently there are also special masks on the market The mask used for anti-smog uses wing-shaped nano-materials and granular activated carbon as the filter element of the mask, which can deeply filter and block PM2.5, bacterial viruses, car exhaust, etc.

However, due to the high density of this mask filter, and its structure that both the exhalation and the filter are on the same filter channel, the mask filter is easily blocked, and the protection efficiency is reduced. Wearing it for a long time will make people feel depressed and uncomfortable. It is not conducive to long-term wearing and use; on the other hand, this kind of anti-smog mask does not fit tightly with the human face.
