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.
