Fig. 3 shows a schematic structural diagram of the oxygen regulating valve provided by the present invention. The oxygen regulating valve 4 comprises a valve body 11, an oxygen channel 7 is arranged in the valve body 11, and two ends of the oxygen channel 7 are respectively communicated with an oxygen inlet 5 and an oxygen outlet 9. Fig. 2 shows a path diagram of oxygen for breathing after the oxygen regulating valve provided by the utility model is arranged. Oxygen supply equipment 1's oxygen gas outlet pipeline 2 is connected with oxygen gas inlet 5, and oxygen gas inlet 5 is connected with the one end of oxygen passageway 7, and the other end of oxygen passageway 7 is connected with oxygen gas outlet 9, and oxygen gas outlet 9 is connected with nasal suction pipe or semi-sealed respirator 3, forms the oxygen passageway promptly. An electromagnetic valve 6 for controlling the opening and closing of the oxygen passage 7 is arranged in the oxygen passage 7.
The oxygen regulating valve 4 further includes a control circuit board 10 and a differential pressure sensor 8. One pressure interface of the differential pressure sensor 8 is communicated with the oxygen outlet 9, and the other pressure interface is communicated with the atmospheric environment, and is used for measuring the pressure difference value between the oxygen outlet 9 and the external environment as a sign for detecting the breathing state of the person. The control circuit board 10 is connected with the electromagnetic valve 6, and the differential pressure sensor 8 is connected with the control circuit board 10. The human body can produce a negative pressure in the snorkel or semi-sealed breathing mask 3 at the in-process of breathing in, and the snorkel or semi-sealed breathing mask 3 is connected with the oxygen gas outlet, through differential pressure sensor 8 alright with gather the snorkel or semi-sealed breathing mask 3 and the external environment between the pressure differential, as the index of judging the human body state of breathing in.
Specifically, the control circuit board 10 adopts a normally open two-position two-way electromagnetic valve with a large-diameter vent, so that when the oxygen regulating valve is not opened, the continuous oxygen supply path of the oxygen supply device is ensured to be smooth. After the oxygen regulating valve is opened, the electromagnetic valve is automatically regulated to be opened and closed through the control circuit board, and multifunctional switching is realized.

The working mode of the oxygen regulating valve is as follows:
oxygen mode for health care: the power switch of the oxygen regulating valve is opened, the system is initialized to automatically close the electromagnetic valve 6, and the oxygen path is cut off. Then the pressure difference sensor 8 senses the inspiration state of the human body, the collected data is transmitted to the control circuit board 10, and whether the human body is in the inspiration state or not is judged according to the sensing threshold set by the program. If the pressure difference signal acquired by the pressure difference sensor 8 is greater than the set threshold value, the air suction is judged, the control circuit board 10 controls the electromagnetic valve 6 to be opened, and the oxygen input from the oxygen inlet 5 is conveyed to the oxygen outlet 9 through the oxygen channel 7 for human body use. If the differential pressure signal collected by the differential pressure sensor 8 is smaller than the set threshold, the control circuit board 10 controls the electromagnetic valve 6 to close, and the oxygen input from the oxygen inlet 5 cannot pass through the oxygen channel 7 and cannot be output for use. The automatic regulation requirements of timely supplying oxygen when a human body inhales and closing oxygen supply when exhales are met, the purpose of saving oxygen is achieved, and the oxygen utilization efficiency of the gas cylinder is improved.
Continuous oxygen supply mode: the power switch of the oxygen regulating valve is closed, so that the oxygen outlet is directly connected with the nasal suction tube or the semi-sealed breathing mask, and continuous oxygen supply is realized. Oxygen enters the oxygen inlet 5 and directly reaches the oxygen outlet 9 through the electromagnetic valve 6 to be supplied to the human body.
