Detailed Description

The present invention will be further described with reference to the following embodiments in conjunction with the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.

In the embodiment, as shown in fig. 1-4, an anti-fogging mask for eyeglasses comprises a mask body 1, straps 2 arranged on two sides of the mask body 1, an exhalation tube 3 penetrating through the lower part of the mask body 1, and a one-way exhalation valve 4 arranged on the exhalation tube 3, wherein the one-way exhalation valve 4 only allows exhalation, a first coating layer 5, a hot gas absorbing mechanism 6 and a second coating layer 7 which are arranged on the inner side of the upper part of the mask body 1 and are sequentially distributed from the upper part to the lower part of the mask body 1, the hot gas absorbing mechanism 6 comprises an oil layer 601 for preventing heat from rapidly diffusing to the outside, a condensing layer 602 for condensing hot gas into water drops, preferably, the condensing layer 602 is a liquid film, a guiding layer 603 and an absorbing layer 604 for absorbing water drops, the absorbing layers 604 are respectively arranged on two sides of the guiding layer 603 and connected through a ventilation layer 605, and a dispersion layer for dispersing the hot gas into the guiding layer 603 is formed between the ventilation layer 605 and the guiding layer 603 Channel 606, hot gas can liquefy through guide layer 603 after getting into dispersion channel 606, and the drop of water after the liquefaction is absorbed by absorbed layer 604 to prevent that hot gas from forming the fog on the diffusion of gauze mask upper portion to the glasses lens, realize preventing the purpose that glasses hazed, prevent that the hazing is effectual.

Preferably, the level of the condensation layer 602 is gradually increased from both ends to the middle.

Further, the direction layer 603 is close to the interval is equipped with a plurality of blend stops 6031 on one side of absorbed layer 604, and is adjacent be formed with between the blend stop 6031 and accomodate groove 6032, the direction layer 603 is close to the interval is equipped with a plurality of arc archs 6033 that are used for with the hot gas liquefaction on one side of the condensation layer 602, and is preferred, and arc arch 6033 can adopt the pearlite sand to implement, and the pearlite sand temperature is 10 ° -15, arc arch 6033 with accomodate groove 6032 one-to-one, arc arch 6033 with condensation channel 6034 has between the blend stop 6031.
