Abstract

Antifog haze gauze mask of gas storage formula in advance belongs to the design and manufacture technical field of gauze mask. On the flexible gluey limit of marginal upper band of the cover body, have the elasticity gasbag in both sides in front at the cover body, have a transom window between two elasticity gasbags, have the soft clamp of bridge of the nose metal on the upper portion of a transom window. The utility model discloses a characteristics have the elasticity gasbag and go out the transom window in cover body both sides, and the people is when breathing in, and the air gets into from the gasbag, through check valve inlet port nasal cavity. Because have an elasticity gasbag, the increase area that admits air, inside in addition have certain space to store the air, can the volume of satisfying the breathing, reduced respiratory resistance. Still because the edge part has the elastic gum limit, can more help sealing. The soft clamp of bridge of the nose metal can prevent that the cover body from droing and dust gets into. The utility model discloses simple structure, reasonable in design. The problem of the existing market attend the universality that lock -joint cover exists is solved.

Description

Pre-air storing type haze mask

Technical field

This utility model belongs to design and the manufacturing technology field of mask

Background technology

Discharge capacity now with industrialization development, toxic gas and dust constantly increases, and the continuous appearance of EI Nino phenomenon, causes the haze weather in China's most area to be continuously increased in addition, brings significant impact to people's life with healthy.According to statistics, the disease brought due to haze weather has made the ratio of various places medical department Number of Outpatients increasing.Therefore mostly select when people go on a journey in haze weather to wear mask.With regard to the toxic gas in current air and dust content, common mask is difficult to prevent from sucking.Therefore haze mask is occurred in that.But existing haze mask is in use very undesirable.If any mask edge seal bad, dust can enter.Also have in front portion with air outlet valve, but because of air outlet valve, the veil of mouth is blocked, and air inlet area reduces, and causes gas-flow resistance big, makes people feel under the weather, even dyspnea.

Summary of the invention

For above-mentioned situation, it is effective that the purpose of this utility model is to provide a kind of anti-haze, and the mask of comfortable wearing, solves existing product Problems existing.

This utility model is adopted the technical scheme that by solving the problems referred to above；With elastic gum limit on the edge of cover body.Sealing function can be played in elastic gum limit.Prevent dust from entering.Before cover body, both sides are with elastic bag, with slinky spring in air bag.At the back side of elastic bag with non-return valve.With outlet window between two elastic bags, with air outlet valve on the back side of outlet window.On the top of outlet window with the soft folder of bridge of the nose metal.In cover body both sides with ear band.Feature of the present utility model is in cover body both sides with elastic bag and outlet window, and people is when air-breathing, and air enters from air bag, and by non-return valve inlet port nasal cavity, during exhalation, non-return valve is closed, and gas breathes out from outlet window, and after exhalation, air outlet valve cuts out.Non-return valve and air outlet valve all play the effect of closing.Because with elastic bag, increasing air inlet area, in addition internal have certain space stored air, it is possible to meets respiratory capacity, reduces respiratory resistance, is comfortable on after therefore wearing.Also as edge part is with elastic gum limit, can be more conducive to seal.Cover gauze can be overlayed on the bridge of the nose by the soft folder of bridge of the nose metal, it is prevented that come off and dust enters.This utility model simple in construction, reasonable in design.Solve the Universal Problems that institute's lock-joint cover exists in the market.
