Air inlet connects secondary filter chamber, and the bottom of secondary filter chamber is connected with air supply chamber, and air supply chamber is arranged on breathing mask, the liquid filter
The top of any side of room sets air induction conduit, and air induction conduit one end is stretched into liquid filter chamber, other end connection suction mechanism.
Beneficial effect：The utility model filters air using suction mechanism, then inputs liquid by air induction conduit and filter
Room, secondary filter chamber carry out multiple times of filtration after, be actively delivered to air supply chamber supply of breathing, it is compact-sized, air-breathing and expiratory resistance it is small,
Breathe it is unimpeded, using solid-liquid combination technological means to air carry out multi-filtering, can effectively filter out particulate in air and easily
Molten harmful substance, good filtration effect, the health of user is ensured.
