Beschreibung
Zusammenfassung:	The oxygen supply valve with the pulse oxygen uptake function comprises a valve body, the side wall of the valve body is provided with a first-stage pressure reduction cavity, a second-stage pressure reduction cavity, a flow limiting cavity and a pulse cavity which are sequentially communicated, and the bottom of the valve body is provided with an air inlet channel which is communicated with the first-stage pressure reduction cavity and used for feeding oxygen. A first-stage pressure reducing valve element set used for conducting first-stage pressure reducing on oxygen is arranged on the first-stage pressure reducing cavity, a second-stage pressure reducing valve element set used for conducting first-stage pressure reducing on oxygen is arranged on the second-stage pressure reducing cavity, a flow limiting assembly used for adjusting the gas output amount is arranged on the flow limiting cavity, and a pulse assembly used for conducting pulse oxygen output is arranged on the pulse cavity. According to the puls
