The gas passage 22 is formed inside the body 21, and opposite ends of the gas passage 22 are open. The first screw hole 24 is formed at one side of the body 21. The second screw hole 26 is formed at one side of the body 21 and is apart from the first screw hole 24. The gas passage 22 has one end connected to the first threaded hole 24 and the other end connected to the second threaded hole 26. A flange 220 is formed on the inner wall surface of the gas passage 22.

An ejector pin 27 is installed in the gas passage 22, a gas inlet passage 270 penetrates through the inside of the ejector pin 27, and the gas inlet passage 270 communicates with the gas passage 22 of the body 21. A check valve member 28 is movably installed at the gas passage 22 corresponding to the blocking edge 220, thereby closing the gas passage 22. The check valve member 28 is made of a material having a low coefficient of thermal derivative. A pressing member 29 is movably installed at one end of the body 21. A hole 290 penetrates through the pressing member 29 in a radial direction. The pressing member 29 is made of a material having a low coefficient of thermal derivative. One end of the pressing member 29 extends into the body 21. Further, one end of the pressing member 29 corresponds to the check valve member 28. A stopper member 292 is installed on an inner wall surface of the gas passage 22, and one end of the stopper member 292 is inserted into the through hole 290 of the pressing member 29. The inner diameter of the through hole of the pressing member 29 is larger than the outer diameter of the limiting member 292, so that the pressing member 29 can be movably displaced.

Further, the first threaded aperture 24 of the body 21 engages the externally threaded section 14 of the gas fill bottle 10. One end of the thimble 27 extends into the bottle opening 12 of the air-filled bottle 10, so that the air inlet passage 270 of the thimble 27 is communicated with the inside of the bottle opening 12.

The adapter assembly 30 includes an adapter 40 and a adapter 50. The adaptor 40 is of a hollow construction, with one end of the adaptor 40 having a first externally threaded section 42 and the other end having a second externally threaded section 44. The adaptor 40 is coupled to one side of the body 21. Specifically, the first externally threaded section 42 of the adaptor 40 engages the second threaded hole 26 of the body 21, communicating the interior of the adaptor 40 with the gas passage 22 of the body 21. The material of the adaptor 40 is a material with a low thermal conductivity, such as plastic, bakelite …, etc.

The adapter 50 is a hollow structure, an internal thread section 52 is provided inside one end of the adapter 50, the adapter 50 is connected to the adapter 40, the internal thread section 52 of the adapter 50 engages with the second external thread section 44 of the adapter, so that an air flow channel 56 is formed inside the adapter 40 and the adapter 50, and the air flow channel 56 is communicated with the air passage 22 of the body 21. Further, the adapter 50 is made of a metal material, such as an aluminum alloy. The adapter 50 may also be made of a material with a low coefficient of thermal conductivity. In addition, the structure of the adaptor 40 and the adaptor 50 may be an integral body, or the adaptor 40 and the adaptor 50 may be divided into two separate parts and connected with each other, and the connection manner may be a screw lock.

Referring to fig. 3, according to the above combination, the air inside the inflator 10 flows to the air passage 22 of the main body 21 through the air inlet passage 270 of the thimble 27, and at this time, the pressing member 29 is pressed, so that one end of the pressing member 29 pushes against the check valve member 28; the check valve member 28 is downwardly displaced so that a gap 222 is formed between the check valve member 28 and the stopper 221, and then, the gas is flushed out from the gap 222 and the pressing member 29 is prevented from being removed from the body 21 by the stopper 292. At this time, the gas flows from the gas channel 22 of the body 21 to the gas flow channel 56 of the adaptor assembly 30, and then the gas flows from the gas flow channel 56 of the adaptor assembly 30 to the outside.

Due to joule thomson effect, the temperature of the gas is reduced when the gas is converted from high pressure to low pressure, so that the adaptor assembly 30 is easily frozen, and the rigidity of the adaptor assembly 30 is reduced to cause damage. It should be noted that the adapter 40 of the present invention is made of a material having a low thermal conductivity, so that the adapter assembly 30 is not easily damaged by joule thomson effect.

In addition, the adapter assembly 30 is connected to the body 21 at an angle smaller than 180 degrees, for example, 90 degrees as shown in the figure. The angles of the above embodiments are merely illustrative, and not restrictive.

The adaptor 74 is of a material having a low coefficient of thermal derivative. The structure and assembly of the present embodiment are substantially the same as those of the previous embodiments, and the difference is that the adaptor assembly 70 is connected to the body 60 in a linear manner. The linear connection is that the connection angle between the adapter assembly 70 and the body 60 is equal to 0 degree or 180 degrees.

The adapter is made of a material with a low thermal derivative coefficient, so that the adapter is not easy to freeze, gas output is facilitated, and the adapter is not easy to use inconveniently due to the problem of freezing when in use. Furthermore, the pressing member and the check valve member can be made of materials with low thermal derivative coefficients, so that the pressing member and the check valve member are not easy to freeze, and the pressing member and the check valve member can have good displacement effect, facilitate the circulation of gas and provide good check effect.
