[0010] Also included is a switch assembly, which is used to open and close the communication hole;

[0011] Also included is a deflation assembly for deflation of a connected alpine tank.

[0012] In a possible design, the switch assembly includes an internal threaded sleeve fixedly mounted on one end of the air inlet passage, the inner wall of the internal threaded sleeve is threadedly connected to a valve stem, a knob is fixedly mounted on one end of the valve stem, and a conical metal seal is fixedly mounted on the other end of the valve stem, and the conical metal seal cooperates with the connecting hole.

[0013] In one possible design, the air release component includes an air release hole and a pressure relief channel opened inside the shell, the air release hole is located below the pressure relief channel, the air release hole passes through the bottom of the shell and is connected to the inside of the connector, the pressure relief channel passes through the top of the shell, a sealing sleeve is fixedly installed on the top of the pressure relief channel, a pressing rod is slidably provided on the inner wall of the sealing sleeve, a sealing sheet is fixedly provided on the outer wall of the pressing rod, a sealing ring is fixedly provided on the top of the sealing sheet and seals with the bottom of the sealing sleeve, a reset spring is provided on the outer wall of the pressing rod, one end of the reset spring is fixedly connected to the bottom of the sealing sheet, and the other end of the reset spring is fixedly connected to the bottom inner wall of the pressure relief channel, an air release exhaust passage exists between the pressing rod and the inner wall of the sealing sleeve, and the air release exhaust passage is used to discharge the gas in the pressure relief channel.

[0014] In a possible design, two sealing rings are fixedly mounted on the outer wall of the valve stem, the distance between the two sealing rings is greater than the inner diameter of the air outlet, and the two sealing rings are used to complete the sealing of the air inlet channel.

[0015] In one possible design, the outer diameter of the sealing plate is larger than the inner diameter of the sealing sleeve, which can ensure a better sealing effect between the sealing plate and the sealing sleeve.

At this time, the gas is inflated from between the inflation channel and the alpine tank, and the gas in the inflation channel is connected to the bottle mouth of the alpine tank through the connecting head to form a sealed cavity, and is also connected to the pressure relief channel through the air relief hole; when the pressure of the gas in the external gas channel is equal to that of the alpine tank, the alpine tank can no longer continue to be inflated. At this time, the valve stem needs to be rotated clockwise to close the connecting hole, and at the same time, the pressing rod is pressed to release some of the pressure in the tank, and then released, and the valve stem is rotated counterclockwise again to open the connecting hole, and then inflation can continue, thereby achieving the effect of rapid inflation.

[0018] The second usage: when the air inlet is not connected to the external gas pipeline, the entire valve body is equivalent to a three-purpose pressure relief valve. After the connecting head is connected to the alpine tank: rotating the valve stem counterclockwise can achieve a mechanical pressure relief; at the same time, you can also directly press the pressing rod to achieve rapid pressure relief while closing the connecting hole; you can also rotate the valve stem counterclockwise and press the pressing rod simultaneously to achieve high-speed pressure relief.

After stopping pressing the pressing rod 15, the sealing sheet 16 rebounds and seals with the sealing sleeve 14 again to stop the pressure relief; then the external gas pipe is connected to the air inlet hole 3, but it is not connected to the gas tank. At this time, rotate counterclockwise The valve stem 7 and the conical metal seal 8 at the front end of the valve stem 7 are away from the connecting hole 5, and the two sealing rings 11 are also away from the connecting hole 5. The connecting hole 5, the air inlet channel 4, and the air outlet channel 10 form an inflation channel, and the two sealing rings 11 can also realize the sealing of the valve stem 7 in the displacement direction, which can prevent the gas from overflowing from one end of the valve stem 7. At this time, the gas is inflated between the inflation channel and the alpine tank, and the gas in the inflation channel is connected to the bottle mouth of the alpine tank through the connecting head 2 to form a sealed cavity, and is also connected to the pressure relief channel 13 through the air release hole 12; when the gas in the external gas channel is equal to the pressure of the alpine tank, the alpine tank can no longer be inflated. At this time, the valve stem 7 needs to be rotated clockwise to close the connecting hole 5, and the pressing rod 15 is pressed to release some pressure in the tank, and then released, and the valve stem 7 is rotated counterclockwise again to open the connecting hole 5, and inflation can continue, thereby achieving the effect of rapid inflation.

[0042] The second usage: when the air inlet 3 is not connected to the external gas pipeline, the entire valve body is equivalent to a three-purpose pressure relief valve. After the connector 2 is connected to the alpine tank: rotating the valve stem 7 counterclockwise can achieve a mechanical pressure relief; at the same time, the pressing rod 15 can be directly pressed while the connecting hole 5 is closed to achieve rapid pressure relief; the valve stem 7 can also be rotated counterclockwise and the pressing rod 15 can be pressed simultaneously to achieve high-speed pressure relief.
