Pulse oxygen valve Technical Field The invention relates to the technical field of oxygen valves, in particular to a pulse oxygen valve. Background The current pulse valve is provided with a normal ventilation air passage and a pulse air passage, and under the ventilation air passage, oxygen with pressure forms a long starting passage, and oxygen is continuously conveyed to a using end. The pulse air passage is formed by using a valve, a pressure plate and the like, driving the valve or the pressure plate to displace and release oxygen under the action of inhalation, and closing the air passage after the inhalation stroke is finished. Compared with a long start mode, the pulse can save the consumption of oxygen more. From the foregoing, it can be seen that the entire valve member is provided with at least two combined flow passages, and when there is no common partial flow passage between the two combined flow passages, the entire valve member is complicated in structure or increased in volume, and in this state, two independent discharge valves are often selected to discharge oxygen. When a common flow channel is arranged between the two combined flow channels, the volume of the whole device can be effectively reduced, but the switching of the channels is involved in the process. If a longitudinal distribution mode is adopted, the whole equipment is longer.
