The main body 10 has an air flow channel 11, which includes an air valve 12, a pressing element 13 and a thimble 14, the air valve 12 is disposed in the air flow channel 11, so that the air flow channel 11 can be substantially divided into a first air flow channel 111 and a second air flow channel 112, and the first air flow channel 111 and the second air flow channel 112 can be selectively communicated with each other according to the adjustment of the air valve 12. In the present invention, the relative positions of the first air flow channel 111 and the second air flow channel 112 are not limited, and in the present embodiment, the first air flow channel 111 is located near the direction connecting the high pressure inflator a, and the second air flow channel 112 is located near the direction connecting the adaptor set 20.
In a first preferred embodiment of the present invention, the valve member 12 includes a displacement rod 121 and a spring 122. The displacement rod 121 is a straight rod, and two ends of the displacement rod are respectively disposed in the first air flow channel 111 and the second air flow channel 112, a protrusion 123 protrudes radially from any section of the displacement rod 121, and a flange 113 protrudes from an inner wall of the air flow channel 11 corresponding to the protrusion 123, and the protrusion 123 can movably pass through the flange 113 to displace in the air flow channel 11. When the protruding portion 123 and the flange 113 are correspondingly abutted, the first air flow channel 111 and the second air flow channel 112 cannot be communicated, so that an air flow cannot flow between the first air flow channel 111 and the second air flow channel 112.
The spring 122 provides an abutting force for the displacement rod 121, so that the protrusion 123 can continuously correspond to the position of the flange 113 when the air nozzle structure is not operated, in this embodiment, the spring 122 is disposed in the first air flow channel 111 and abuts against the protrusion 123 toward the second air flow channel 112.

The thimble 14 is disposed in the first air flow passage 111 and close to the connection with the high pressure inflator A, the thimble 14 is a hollow needle, and a tip thereof is disposed toward the open end. When the main body 10 is assembled with the high pressure inflator a, the tip of the thimble 14 can pierce the high pressure inflator a, so that the air flow is released from the interior of the high pressure inflator a into the first air flow passage 111.
In the second preferred embodiment of the present invention, the flange 113 does not define a protrusion connecting the inner wall of the flow channel 11. For example, the air valve member 12 includes a housing 124, the housing 124 is a hollow rod-shaped housing, any area of the outer surface of the housing includes a threaded surface 125, and a threaded section 126 is disposed on the inner wall of the air flow channel 11, so that the air valve member 12 can be screwed into the air flow channel 11 through the threaded surface 125 to fix the position of the air valve member in the main body 10, thereby avoiding the influence of the air pressure of the high pressure inflator a. The flange 113 is detachably disposed on the main body 10, so as to greatly simplify the structure of the airflow channel 11 in the main body 10, and effectively reduce the manufacturing cost and time of the main body 10.
The displacement rod 121 is movably disposed in the housing 124, and the inner surface of the housing 124 is protruded with the flange 113 corresponding to the protrusion 123, so that the first air channel 111 and the second air channel 112 can be selectively connected according to the control of the air valve 12. A retaining edge 1241 is radially protruded from the inner wall of the housing 124 close to the first air flow passage 111, the spring 122 is sleeved on the periphery of the pressing element 13, and two ends of the spring respectively abut against the protrusion 123 and the retaining edge 1241, so that when the body 10 is not operated, the protrusion 123 can continuously abut against the flange 113 correspondingly.
Preferably, an airtight member 127 is sleeved at the end of the displacement rod 121 protruding from the first air flow channel 111, the outer diameter of the airtight member 127 is larger than the inner diameter of the housing 124, and when the airtight member 127 is not operated, the airtight member 127 abuts against and seals the opening of the housing 124 in the second air flow channel 112 in cooperation with the abutting force provided by the spring 122, so that the air valve 12 can exhibit an excellent airtight effect, the air flow in the air flow channel is prevented from flowing or leaking when the air valve structure is not used, the structural relationship between the airtight member 127 and the housing 124 abutting against each other is also prevented, and the displacement rod 121 is prevented from being disengaged or damaged by the air pressure of the high-pressure air bottle a when the displacement rod 121 is used.

For example, the third embodiment of the present invention is different from the first embodiment in that the air seal member 127 can be sleeved around the outer periphery of the displacement rod 121 in the direction of the first air flow channel 111 relative to the protrusion 123, the outer diameter of the air seal member 127 is preferably larger than the protrusion 123, the spring 122 is disposed in the first air flow channel 111 and abuts against the air seal member 127, so that when the protrusion 123 continuously corresponds to the position of the flange 113, the air seal member 127 abuts against the flange 113 by the abutting force provided by the spring 122 and generates the effect of closing the air flow channel 11.
The adapter 20 is connected to the body 10, and the adapter 20 can be made of a material with a low thermal conductivity, such as plastic or bakelite, so that the adapter 20 is not easily deformed due to temperature change caused by high pressure release during inflation, and the problem of difficulty in detaching the air nozzle structure or damage due to freezing is avoided. The adapter 20 has a gas channel 21, and one end of the gas channel 21 is connected to the second gas channel 112. The adapter set 20 may further include an adapter 22 and an adapter 23, the adapter 22 and the adapter 23 are not limited to be made of the same material, and two ends of the adapter 22 are respectively connected to the adapter 23 and the body 10.
When the air faucet structure of the present invention is used, when the body 10 is engaged with the high pressure inflator A, the tip of the thimble 14 pierces the high pressure inflator A, the air flow is released from the interior of the high pressure inflator A and enters the first air flow channel 111, at this time, because the protrusion 123 of the air valve 12 abuts against the flange 25, the air is blocked in the first air flow channel 111 and cannot enter the second air flow channel 112.
Referring to fig. 3, the pressing portion 131 is pressed and the displacement rod 121 is pushed to move toward the first air flow channel 111, so that a gap is formed between the air valve 12 and the flange 113, and the air flow is guided to the second air flow channel 112 and the adaptor set 20 through the gap as indicated by the arrow. When the pressing force applied to the pressing member 13 is removed, the spring 122 pushes the air valve 26 to move toward the second air flow channel 112, the protrusion 123 abuts against the flange 113 correspondingly, and the air flow is blocked in the first air flow channel 111.
Preferably, the pressing member 13 is made of a material with a low thermal conductivity as the adapting group 20, which not only can prevent a user from being frozen during use, but also can prevent the pressing member 28 from being deformed or damaged due to freezing caused by temperature shock generated by high pressure release, and exhibit a good displacement effect, so as to effectively prevent the air flow from leaking between the pressing member 13 and the body 10 and maintain a good inflation efficiency.
Further, in order to prevent the surface of the body 10 of the air faucet structure from being damaged by freezing due to the sudden drop in temperature, the body 10 is provided with a temperature isolation member, which can be covered on the surface of the body 10 or combined with the body 10.
