[Prior art]

 Air quality is increasingly deteriorating, and fine particles, toxic substances, exhaust gases from cars and motorcycles and various polluting gases from factories severely injure human respiratory organs. Active research is currently being conducted on how to improve air quality in each country.However, in the absence of the current drastic solutions, personal health is a negative measure of wearing a mask. I have to rely on it. Motorcycle drivers are among the severely harmed by current air pollution, with the largest percentage of motorcycle drivers wearing masks.

[0003] Early mask products were manufactured by sewing a cloth, which had only a single function of dust protection. However, in today's increasingly severe air pollution situation, such early masks, which remove dust with a cloth or transition, can no longer achieve the true requirements of filtering air. Therefore, masks containing activated carbon have become commercially available.

[0004] This activated carbon mask has been widely promoted and accepted, and is made of a cotton material and containing fine activated carbon therein. According to the driver, such a mask could not be said to be as effective. The disadvantages are as follows. 1. Traditional cotton masks or charcoal-filled masks are said to be worn by helmet-wearing drivers. It became severe and affected driving safety. 2. The well-known mask with activated carbon has a relatively good filtering effect because fine activated carbon is mounted inside. However, such a mask containing activated carbon cannot fix the activated carbon in a uniformly distributed state, so that the activated carbon is concentrated at the lower portion of the mask to form a dumpling. For this reason, the filtration effect was significantly impaired. 3. Well-known masks are used in a discarding manner, but ordinary people discard or replace them only when the masks they use have already lost their filtering function and they can no longer withstand dirt. Due to these usage habits, the use of masks does not solve the problem of air pollution affecting human health. In addition, masks that have no filtration function cannot be replaced because only the filter material is discarded, so the entire mask must be discarded, creating a cost burden for users and the problem of dust.

[0005]

[Problems to be solved by the invention]

 Therefore, an object of the present invention is to provide a kind of anti-fog mask, which solves a number of problems of known masks and a number of problems that occur when a motorcycle driver wears a mask. Thus, the filtering property of such a protective mask is enhanced.

[0006] Specifically, the features, objects, and advantages of the present invention are as follows. 1. Separate duct structure design is adopted for the intake and exhaust of the present invention, and the exhaust is turned to both sides (or below the filter recess), so the water vapor is quickly discharged to both sides (or below) between the intake and exhaust. This eliminates the problem of obstruction of the line of sight caused by clouding, especially when wearing a helmet and glasses at the same time without discharging the entire front as in a well-known mask. 2. The design of the present invention employs replaceable filter media, which achieves economic savings, long-term use, and reduces waste problems. In addition, the filter media exchange structure has been simplified and has practicality, convenience and inventive step. 3. The design of the filtering section of the present invention achieves the best filtering effect with a centralized type and absoluteness, and solves the drawback that the activated carbon of the well-known mask containing fine activated carbon concentrates downward and impairs the filtering effect. I have. 4. The design of the present invention can be combined with a contact type eye mask by a projection provided on the top outside of the center of the mask body, thereby forming a mask device used in a special environment or temporary fire evacuation. 5. Under the substantial creative spirit of the present invention with the above features, by adopting a luminous or reflective design on the outer layer of the entire mask body in response to the requirements of the motorcycle driver, when the motorcycle is driven at night, Be eye-catching and secure.
