Road 13 is made of the multilayer chamber being formed in mask 1.The gas of user's exhalation is after the heat exchange of multilayer chamber, the gas of exhalation
It is unanimous on the whole with the gas temperature of external environment, it avoids the gas of exhalation from blowing to and generates water mist on glasses.
The gas of mask 1 according to an embodiment of the present invention, user's exhalation is carried out by heat exchanger channels 13 and outside air
Heat exchange, in this process, the gas of exhalation can all be cooled by each layer of chamber specifically exports discharge up to gas passes through,
Gas at this time is unanimous on the whole with ambient temperature, and the steam-laden gas of richness of exhalation would not be because of the rising of thermal current
And it is atomized eyeglass.
The main reason for spectacle lens haze is because winter temperature is relatively low, and the temperature of glasses equally can be relatively low, and hot
When gas reaches the spectacle lens of low temperature, hot gas will condense on the spectacle lens of low temperature, to haze.In order to solve this problem,
Heat exchanger channels 13 are set in the present invention, are exchanged heat during air-flow with external environment, so as to reduce exhaled gas
Temperature, when the temperature gap of exhaled gas temperature and external environment is smaller, even if gas exhalation reaches eyeglass, because will not
The problem of hazing.

From and not towards glasses direction, so that most gases are logical after the gas of exhalation enters second layer chamber 132 from first layer chamber Room 131
The lesser exhaust outlet 1311 of resistance is crossed to be discharged.
Mask 1 according to an embodiment of the present invention, exhaled gas enter the sky of second layer chamber 132 after first layer chamber 131
Between, the direct contact lenses of exhaled gas are avoided, the gas into second layer chamber 132 can cool down, and be arranged in second layer chamber 132
Have far from and not towards the exhaust outlet in glasses direction 1311 so that the gas of exhalation enters second layer chamber 132 from first layer chamber 131
Afterwards, most gases are discharged by the lesser exhaust outlet 1311 of resistance, rather than rush at glasses, and when temperature is lower, it is steamed rich in water
The thermal current of gas can make glasses atomization that people be caused not see.
Wherein, as shown in figure 3, the other end of heat exchanger channels 13 is equipped with breather valve 1312.When exhaling, the gas of discharge is just
Pressure blows valve block open, rapidly excludes exhaust gas, feeling of oppression and heat when reducing using mask 1, and negative pressure when air-breathing can be automatically by valve
