Embodiment Construction

[0018] Such as Figure 1 to Figure 2 As shown, basically, the anti-fog mask 1 of the present invention comprises a cover body 11, and its two sides are oppositely provided with harness 12, as figure 1 As shown, the harness 12 is a ring-shaped elastic ear strap, so that the user can hang the anti-fog mask of the present invention on the ears on both sides of the user's head, but it is not limited thereto. When the harness 12 is implemented It must also be a long strap so that the user can bind the anti-fog mask of the present invention to the upper and lower sides of the user's head.

[0019] The technical feature of the anti-fog mask of the present invention is that an exhaust structure 13 is arranged below the inner surface of the cover body 11. When the exhaust structure 13 is implemented, it is a strip-shaped abutment piece 131, and the two ends 131a of the abutment piece 131 It is fixed on both sides below the inner surface of the cover body 11, and the length of the top ...

Abstract

The invention discloses an antifog mask. The antifog mask consists of a mask body and an exhausting structure arranged on the lower portion of the inner side surface of the mask body. Two side edges of the mask body are provided with tying cords oppositely; the exhausting structure is a strip-shaped pushing contact sheet and the two ends of the pushing contact sheet are fixedly connected with the two lower sides or ends of the inner side surface of the mask body; and the top edge of the pushing contact sheet is provided with at least one bevel, so that the length of the top edge is shorter than that of the bottom edge of the pushing contact sheet and therefore a through hole is formed between the pushing contact sheet and the lower portion of the inner side surface of the mask body. When the antifog mask is in use, the air expired by a user who wears glasses is exhausted outside from the bottom edge of the inner side surface of the mask body through the through hole, and therefore the defect of vision blurring caused by the fogging of the glasses is overcome.

Description

technical field [0001] The invention relates to a mask, especially an anti-fog mask. Background technique [0002] Mask is that people are used to cover mouth and nose position on the face and the cover body around mouth and nose.

Therefore, mask has become one of the necessary daily necessities of modern people. [0003] As mentioned above, although the mask can block germs, dust or floating substances to protect the mouth and nose, when in use, if the ambient temperature is lower than the human body temperature and the user wears glasses, the human body will exhale The hot air will rise along the mask and cause the glasses lenses to fog up, especially when driving or riding a motorcycle, the fogging of the lenses will cause blindness, which is not only inconvenient for...
