[0022] In one embodiment of the present invention, reference Figure 1~Figure 4 As shown, a medical inflation switch solenoid valve is provided, comprising an air outlet plate 10, an air passage plate 20 and a switch valve 30. An air outlet pipe 11 extends upward from the air outlet plate 10, an air passage 21 is arranged in the air passage plate 20, and an air inlet pipe 22 extends to one side of the air passage plate 20. The air outlet plate 10 is pressed on the top of the air passage plate 20, the air inlet pipe 22 is connected with the air passage 21, the air outlet pipe 11 is connected with the air passage 21, the switch valve 30 is arranged below the air passage plate 20, and the telescopic end of the switch valve 30 is arranged in the air passage 21, which is used to block or loosen the air outlet pipe 11. In this embodiment, the opening of the oxygen bag is set on the outlet pipe 11, and oxygen enters from the air inlet pipe 22, then passes through the air passage 21, flows to the outlet pipe 11, and then stays in the oxygen bag for collection. The outlet pipe 11 is blocked or opened by the telescopic end of the switch valve 30, thereby controlling the connection or closure of the outlet pipe 11 and the air passage 21. The control method is simple, the control speed is fast, and oxygen waste is avoided.

[0023] Specifically, refer to Figure 1~Figure 4As shown, the air passage 21 is arranged in the air passage plate 20 and is parallel to the air passage plate 20. A clamping groove 23 is also arranged below the air passage 21. The clamping groove 23 is used to clamp the front end of the switch valve 30, and the switch valve 30 covers the clamping groove 23. In this embodiment, the front end of the switch valve 30 is clamped in the clamping groove 23, and the air passage 21 is closed at the same time to prevent oxygen from flowing out of the clamping groove 23 and causing waste. In addition, the switch valve 30 is clamped in the air passage plate 20 to prevent the switch valve 30 from falling.

[0024] Specifically, refer to Figure 1~Figure 4 As shown, a guide ring 24 is further provided in the air passage 21, and the guide ring 24 is located below the air outlet pipe 11. The guide ring 24 is used to guide the telescopic end of the switch valve 30 to approach or move away from the air outlet pipe 11. In this embodiment, the guide ring 24 is used to guide the telescopic end of the switch valve 30 so that the telescopic end of the switch valve 30 is aligned with the air outlet pipe 11.

[0025] Specifically, refer to Figure 1~Figure 4 As shown, an air storage chamber 25 is further provided in the air passage plate 20, and the air storage chamber 25 is arranged on both sides of the guide ring 24, and the air storage chamber 25 is connected with the air passage 21. In this embodiment, the air storage chamber 25 can speed up the inflation speed of the oxygen bag. When the oxygen bag is inflated, the telescopic end of the switch valve 30 extends into the switch valve 30, and then the air inlet pipe 22 takes in air, and the oxygen flows into the outlet pipe 11 in the air passage 21. However, since the oxygen has a certain flow rate, the outlet pipe 11 and the air passage 21 are perpendicular to each other, which will slow down the speed of oxygen entering the outlet pipe 11. The oxygen will also flow into the air storage chamber 25 while passing through the air passage 21. The oxygen in the air storage chamber 25 will also flow into the outlet pipe 11 as the air pressure changes when the oxygen passes through the air passage 21, thereby speeding up the gas storage speed of the oxygen bag and improving the work efficiency.

[0026] Specifically, refer to Figure 1~Figure 4 As shown, the air passage plate 20 is provided with a plurality of threaded holes 26, the air outlet plate 10 is provided with a plurality of through holes 12 corresponding to the threaded holes 26, and the screw rods 13 pass through the through holes 12 and are connected with the threaded holes 26, so as to connect the air passage plate 20 and the air outlet plate 10. In this embodiment, the air tightness between the air outlet plate 10 and the air passage plate 20 can be maintained by connecting through the threaded screw holes, oxygen waste can be avoided, and the assembly is simple and quick.

[0027] Specifically, refer to Figure 1~Figure 4As shown, the air outlet plate 10 is provided with four air outlet pipes 11 distributed in a rectangular array, and the air passage plate 20 is provided with two air passage channels 21, one end of the air passage channel 21 is connected to the air inlet pipe 22 and the other end is arranged in the air passage plate 20 to form a closed loop, and the air passage channel 21 is connected to the two air outlet pipes 11. It also includes four switch valves 30, each of which corresponds to each air outlet pipe 11. In this embodiment, each switch valve 30 can independently control each air outlet pipe 11, and multiple oxygen bags can be inflated at the same time, thereby improving work efficiency.

[0028] Specifically, refer to Figure 1~Figure 4 As shown, a protective shell 31 is also sleeved on the outside of each switch valve 30, and a clamping block 32 is extended upward from the upper end of each protective shell 31, and the clamping block 32 is used to clamp the bottom of the gas plate 20. In this embodiment, the protective shell 31 can effectively protect the switch valve 30 to prevent the switch valve 30 from being damaged due to impact, and at the same time, the clamping block 32 clamps the gas plate 20 to improve working stability.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
