[0028] Embodiment 1: In some embodiments, please refer to the Figures 1 - 4 of the specification drawings. A gas nozzle capable of rapid air intake includes a gas transmission pipe 1.

[0029] A valve core 2 is arranged inside the gas transmission pipe 1.

[0030] An air inlet 3 is arranged at the upper end of the valve core 2; an installation thread 5 is arranged on the outside of the valve core 2; a connection block 10 is fixedly connected to the lower end of the valve core 2; an air outlet 4 is formed on the side wall of the connection block 10, and the air outlet 4 is communicated with the inner pipe of the valve core 2 and the air inlet 3; a sealing ring 6 is fixedly connected to the lower end of the connection block 10; a groove 11 corresponding to the shape of the connection block 10 is arranged on the inner wall of the gas transmission pipe 1; the valve core 2 is threadedly connected with a nut 7 through the installation thread 5; a tapered surface 9 cooperating with the sealing ring 6 is arranged on the inner wall of the gas transmission pipe 1; the material of the sealing ring 6 is high-temperature-resistant nitrile rubber; the diameter of the valve core 2 is 3.5 mm; the length of the valve core 2 is 15 mm; the valve core 2 is made of stainless steel; the length of the air outlet 4 accounts for 1 / 3 of the total length of the valve core 2.

[0031] In the present utility model, when inflation is required, the operator rotates the nut 7 to move the nut 7 upward, pushing the valve core 2 to drive the connection block 10 downward. The connection block 10 drives the sealing ring 6 to move downward away from the tapered surface 9. At this time, the air inlet 3 is inflated, and the gas flows through the inside of the valve core 2 from the air inlet 3 and finally flows to the air outlet 4 to achieve rapid air intake. When the inflation is completed, the operator rotates the nut 7. After the lower end of the nut 7 fits with the upper end of the gas transmission pipe 1, the valve core 2 drives the connection block 10 to move upward under the limiting action of the groove 11.
