a lip valve;

the upper cover of the patient valve is buckled with the lower cover of the patient valve, and the lip valve is positioned between the upper cover of the patient valve and the lower cover of the patient valve.

Preferably, the lower cover of the patient valve comprises a lower vent pipe, a groove and a female buckle, the groove is arranged on the lower vent pipe, and the female buckle is arranged on the outer side of the groove.

Preferably, a lock catch is arranged on the outer side of the female buckle and is in contact with the protrusion.

Preferably, the catch and the projection are an interference fit.

Preferably, the upper cover material of the patient valve is PC, and the lower cover material of the patient valve is PP.

Preferably, the bulge is V-shaped, a sealing groove matched with the bulge is formed in the lock catch, and the bulge is clamped in the sealing groove.

To sum up, this utility model's a novel patient valve has following beneficial effect: the patient valve is composed of only three parts, is simple in structure, convenient to assemble and high in assembly speed, does not need a complex assembly process, and improves the assembly speed; the lower cover of the patient valve is made of PP material, the upper cover of the patient valve is made of PC material, the soft and hard combination part adopts interference fit, after assembly, the soft PP is deformed and then closely matched with the hard PC to form a sealing surface, and the problem of part breakage in the assembly process is avoided.
