The utility model adopts air-breathing and the circulation of expiration subchannel, have easy to use, filter efficiency is high, filtering net plate is changed easily advantage.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A--A view of Fig. 1;
Fig. 3 is use view of the present utility model.
The specific embodiment
Consult Fig. 1, Fig. 2, the utility model comprises breathing catheter 1, air inlet cover body 3, exhaust cover body 12, air suction valve 8, exhaust valve 14, filter screen 6, screen covering 18, frenulum 19 and link 21, described air inlet cover body 3 is rectangular housing, its front is provided with air inlet 11 and air inlet cover plate 7, one side is provided with breathing catheter interface 4, the another side is uncovered, exhaust cover body 12 is rectangular housing, and the one side is provided with exhaust valve interface 13, the another side is provided with exhaust cover plate 16; The opening end of described air inlet cover body 3 is communicated with through bend pipe with exhaust cover body 12 exhaust valve interfaces 13 ends, breathing catheter 1 is communicated with the breathing catheter interface 4 of air inlet cover body 3 through flexible pipe, air suction valve 8 is located on the inwall of air inlet cover body 3 air inlets 11, exhaust valve 14 is located on the exhaust valve interface 13 in the exhaust cover body 12, filter screen 6 is located in the air inlet cover plate 7, described breathing catheter 1, air inlet cover body 3 and exhaust cover body 12 are two and be symmetrical arranged, link 21 is connected between the two air inlet cover bodies 3, screen covering 18 is wrapped in the outside of air inlet cover body 3 and exhaust cover body 12, and frenulum 19 is connected on the housing of exhaust cover body 12.
Described air suction valve 8 is comprised of air suction valve seat and air-breathing diaphragm 5, and air-breathing diaphragm 5 is covered on the air suction valve seat.
Described exhaust valve 14 is comprised of exhaust valve seat and exhaust diaphragm 15, and exhaust diaphragm 15 is covered on the exhaust valve seat.
Be provided with filtering net plate 61 and packing ring 62 in the described filter screen 6.
