Face mask capable of preventing fogging of glasses

Abstract

The invention discloses a face mask capable of preventing fogging of glasses. According to the technical scheme, the face mask is characterized in that by forming an independent inhaled air and exhaled air flowing channel, and the exhaled air flows out along the designed channel and cannot flow to the upper portion of the nose, so that fogging of the glasses is avoided. In order to solve the problem that the inhalation resistance is increased due to the design of the independent flowing channel, a special respiration assisting device is arranged, the respiration assisting device comprises a chamber, an elastic air bag is arranged in the chamber and connected with an exhalation pipe, the chamber is connected with an inhalation pipe, the exhalation pipe is connected with an exhalation pipe control device, and accordingly, when exhalation is conducted through the exhalation pipe, because the air bag becomes large, the air in the chamber can be discharged into the inhalation pipe for inhalation of people. When one time of exhalation is completed, the exhalation pipe control device discharges the air in the air bag, because the air bag becomes small, the outside air enters the chamber due to air pressure difference, so that the aim of assisting the respiration is achieved. By means of the face mask, fogging of the glasses can be avoided to the greatest extent, and the respiration assisting function is achieved.

Description

[0001] This application is a divisional application of an invention patent application named: An anti-fogging mask for glasses, with the application date: February 24, 2017, and the application number: 2017101027537. technical field [0002] The invention relates to a mask, in particular to a mask for preventing glasses from fogging. Background technique [0003] 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. [0004] Smog is the result of the interaction between specific climatic conditions and human activities. The economic and social activities of a high-dens...

Problems solved by technology

[0008] 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 hole, and a part will still be discharged through the top of the mask, thereby still causing the glasses to be fogged
