[0002] Traditional outdoor oxygen supply method mainly includes two kinds: one is to use small portable oxygen generator to realize continuous oxygen supply, and the other is to supply oxygen through oxygen cylinder (oxygen storage). In outdoor, especially in harsh environment such as plateau, due to the large amount of oxygen demand and long time, portable oxygen generator becomes less applicable due to noise problem and limited battery endurance and other factors. Therefore, in this kind of environment, oxygen cylinder becomes a more ideal choice.

[0003] However, for personnel who need long time outdoor work, carrying large capacity oxygen cylinder is not only inconvenient, but also how to effectively use oxygen resources to avoid waste becomes an important issue. At present, oxygen output is usually controlled by oxygen controller. Most of such equipment on the market has relatively simple structure, mainly relying on electromagnetic valve switch to adjust oxygen flow. However, for the demand of more accurate control of oxygen output frequency, additional electronic pulse type control device is often required.

DETAILED DESCRIPTION

[0020] In the following description of the utility model, the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only used for the convenience of describing the utility model and simplifying the description, and not for indicating that the device must have a particular orientation.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0022] like Figures 1 to 5 As shown, the integrated electronic pulse control valve of this utility model includes a housing, which comprises an upper cover 2 and a lower cover 3 that are fitted together. The lower cover 3 is sleeved on a valve seat 1, and the valve seat 1 has a filling port 5 that connects to the oxygen outlet of an oxygen cylinder. The lower cover 3 contains an integrated air passage 7, a regulating valve 8, a solenoid valve 9, a pressure reducing valve 10, a pressure reducing valve adapter 11, and a battery 12. One end of the integrated air passage 7 has an oxygen outlet 6 that extends out of the lower cover 3. A control board 4 is located above the integrated air passage 7 and is fitted inside the upper cover 2. The lower cover 3 and the upper cover 2 are annular, and the control board 4 is an annular PCB board.

[0023] like Figure 4 As shown, the oxygen cylinder's outlet is connected to the filling port 5. The inner port of the filling port 5 is connected to the inlet of the pressure reducing valve 10 via a pressure reducing valve adapter 11. The outlet of the pressure reducing valve 10 is connected to the inlet of the integrated airway 7 via a solenoid valve 9. The outlet of the integrated airway 7 is connected to the oxygen outlet 6 via a regulating valve 8. The regulating valve 8 is equipped with a regulating valve knob 14, which is located below the lower end cap 3. A differential pressure sensor 13 is installed inside the pipeline of the pressure reducing valve adapter 11.

[0024] Oxygen from the oxygen cylinder enters the valve seat 1 through the filling port 5, passes through the pressure reducing valve adapter 11 to enter the pressure reducing valve 10, and then enters the integrated gas channel 7 through the solenoid valve 9. After flowing out of the integrated gas channel 7, it enters the oxygen outlet 6 through the regulating valve 8 and flows out.

[0025] like Figure 5 As shown, the control board 4 is provided with a charging port 15 for charging the battery 12, and the upper cover 2 has a through hole that matches the charging port 15, and the through hole covers the charging dust cover 16.

[0026] After the control valve is activated, when the human body is inhaling, the differential pressure sensor 13 detects that the air pressure in the pipeline of the pressure reducing valve adapter 11 is in a negative pressure state, and sends a signal to the control board 4. The control board 4 controls the solenoid valve 9 to open. At this time, most of the oxygen enters the pressure reducing valve 10 from the integrated airway 7, and a small portion of the oxygen enters the differential pressure sensor 13 through a branch, and the differential pressure sensor 13 monitors the oxygen pressure at the air inlet.

[0027] If the inlet pressure is higher than the upper limit of the set value range, an alarm signal is sent to the control panel 4, the control panel 4 controls the electromagnetic valve 9 to close, preventing high pressure oxygen from causing harm to the human body; if the integrated airway 7 pressure is lower than the lower limit of the set value range, a low pressure alarm is given. If the integrated airway 7 oxygen pressure is not over-pressured, the oxygen continues to enter the electromagnetic valve 9 from the pressure reducing valve 10 to the oxygen outlet nozzle 6 and is inhaled into the body by the person.

[0028] Compared with the conventional electronic breathing response pulse oxygen supply valve, the integrated electronic breathing response pulse oxygen supply valve has a more compact structure, occupies a smaller space, is relatively lighter in weight, has better wrapping and stronger protection, and is less likely to be damaged.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
