Wherein, the inboard is connected as a single entity about described steam cohesion plate and housing epicoele, its downward-sloping 15～75 °, all leaves vapor channel on top on the housing epicoele with between going to the bottom.Between about the steam cohesion plate, parallel air flue is arranged, also leave the gap between cohesion plate and the last cavity wall front and back.
The utility model has following advantage compared with prior art:
1, the utlity model has the characteristics of Wet-dry, inject clear water in cavity of resorption and epicoele, with water-wet, anti-dust performance is good, as point salt or vinegar a little in clear water, also can have certain sterilization.The installing filtering material as active carbon, has filtration, purification and gas defence function in the following air intake duct;
Both prevent dust, poison gas when 2, wearing, do not influenced people's communication again, convenient and practical.
3, except that sealing ring by rubber make make by sponge with filtering layer, make by non-toxic plastic, wear very light comfortable.
4, owing to adopt the steam cohesion plate structure that tilts to install, the steam of process is condensed on it, the water droplet of cohesion is back to cavity of resorption because of the gravity effect again, thereby makes the people more feel with fresh air, comfortable.
