Embodiment 1

[0031] Embodiment one: a kind of mouth mask that can prevent glasses from fogging, such as Figure 1 to Figure 8 As 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 capable of preventing fog on glasses. According to the technical scheme, the mask is characterized in that independent inhaling and exhaling flow passages are provided so that exhaled gas flows along the designed pass without flowing above the nose, and fogging of glasses is avoided accordingly; in order to prevent increase in inhalation resistance due to the designof the independent flow passages, a special breath assist is provided which comprises a chamber, an elastic balloon is arranged in the chamber and is connected with an exhaling tube, the chamber is connected with an inhaling tube, the exhaling tube is connected with an exhaling tube control device, the balloon enlarges when exhaling is performed via the exhaling tube, air in the chamber may be discharged into the inhaling tube for a user to breathe, the exhaling tube control device discharges the gas in the balloon after single breathing, external air enters the chamber under the action of pressure difference since the balloon diminishes, and assisted breathing is achieved accordingly. The mask of the invention can prevent fogging of glasses to maximum extent and can assist in breathing.
