Problems solved by technology

[0007] However, during the use of the above-mentioned mask, due to airtightness, the exhaled hot air will not be completely discharged through the set through holes, but a part will still be discharged through the top of the mask, which will still cause the glasses to be fogged

Embodiment 1

[0030] Embodiment one: a kind of anti-fogging mask for glasses, such as Figure 1 to Figure 8As shown, it includes a cover body 1, and the two sides of the cover body 1 are respectively connected with hanging ears 2. The cover body 1 includes a front layer L1 and a back layer L2, and a filter L3 is also arranged between the front layer L1 and the back layer L2. A nose line L4 is also sewn into the L1 and the back layer L2 to form a bionic shape that fits the bridge of the nose. Through the hanging ear 2, the user can easily put the mask on, and at the same time, the filter element L3 in the middle of the front layer L1 and the surface layer can play the effect of filtering the haze. The front layer L1 and the back layer L2 are also provided with a nose The line L4 and the nose line L4 can be attached to the nose, so that unfiltered air can be guaranteed not to enter the human respiratory tract through gaps during use.

Abstract

The invention discloses a mask with a function of preventing glasses from fogging. The technical scheme of the mask is characterized in that independent inhaling and exhaling flow channels are formed, so that exhaled gas flows out according to the designed channel and cannot flow to the position above the nose, and fogging of the glasses is avoided; in order to solve the problem of increase of inhaling resistance caused by design of the independent flow channels, a special breathing assistant device is arranged and comprises a cavity, an elastic air bag is arranged in the cavity and connected with an exhaling tube, the cavity is connected with an inhaling tube, the exhaling tube is connected with an exhaling tube control device, when a person exhales through the exhaling tube, the air bag expands to enable air in the cavity to be discharged into the inhaling tube for inhalation, when one-time exhalation is finished, the exhaling tube control device discharges gas in the air bag, the air bag shrinks, and outside air enters the cavity under the action of atmospheric pressure difference, so that the purpose of assistance in breathing is achieved. The mask can prevent the glasses from fogging to the greatest extent and has the breathing assistant function.

Description

technical field [0001] The invention relates to a mask, more specifically, it relates to an anti-fogging mask for glasses. Background technique [0002] A mask is a sanitary product, generally refers to a device worn on the mouth and nose to filter the air entering the mouth and nose to block harmful gases, odors, and droplets from entering and exiting the wearer's mouth and nose, made of gauze or paper. Masks have a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, wearing a mask has a very good effect when working in a polluted environment such as dust. [0003] Smog is the result of the interaction between specific climatic conditions and human activities. The economic and social activities of a high-density population will inevitably emit a large amount of fine particulate matter (PM 2.5). Once the emission exceeds the atmospheric circulation capacity and carrying capacity, the concentration of fine particulate m...
