[0032] See also Figure 1-Figure 8 The embodiment of the utility model proposes a quick-release air nozzle with a deflation function. The quick-release air nozzle with a deflation function can deflate the tire when connected to the tire without removing the quick-release air nozzle. On the other hand, the tire pressure detection function of the inflation device can detect the tire pressure in real time, so that the amount of deflated air pressure can be accurately known. In order to achieve the above technical purpose, the quick-release air nozzle with a deflation function includes a first tube body 10, a second tube body 20 and a deflation device 30, and the specific structure is described as follows:

[0033] The first tube body 10 includes an inflatable connection end 11 and a fitting end 14, and the second tube body 20 includes an air nozzle connection end 21 and a notch end 22, wherein the notch end 22 is provided with a support portion 221. The first tube body 10 and the second tube body 20 are both provided with a central channel. The central channels of the first tube body 10 and the second tube body 20 are connected to each other.

[0034] The inflation connection end 11 of the first tube body 10 is used to connect with the inflation device; the fitting end 14 of the first tube body 10 is embedded in the notch end 22 of the second tube body 20 along the support portion 221, and the first tube body 10 and the second tube body 20 are connected to each other; the air nozzle connection end 21 of the second tube body 20 is used to connect with the tire air nozzle. Specifically, the inflation connection end 11 of the first tube body 10 is used to connect with the inflation device, and the inflation device is used to inflate the tire. Its structure is well known to those skilled in the art and is not specifically limited by the present utility model. The inflation device is usually provided with a tire pressure detection module, which can detect the tire pressure when inflating the tire.

[0035] The deflation device 30 is disposed on the first tube body 10 , wherein when the deflation device 30 is opened, the first tube body 10 is connected to the outside, thereby achieving deflation of the tire.

[0036] Furthermore, when the deflation device 30 is closed, the deflation device 30 will not leak air, and the deflation device 30 will not block the first tube body 10, so that inflation can be performed normally.

[0037] According to the technical solution of the embodiment of the utility model, the quick-release air nozzle with deflation function comprises a first tube body 10, a second tube body 20 and a deflation device 30; the first tube body 10 comprises an inflation connection end 11 and a fitting end 14, the second tube body 20 comprises an air nozzle connection end 21 and a notch end 22, and the notch end 22 is provided with a support portion 221; the inflation connection end 11 of the first tube body 10 is used to be connected to the inflation device; the fitting end 14 of the first tube body 10 is embedded into the notch end 22 of the second tube body 20 along the support portion 221, and the first tube body 10 and the second tube body 20 are connected to each other; the air nozzle connection end 21 of the second tube body 20 is used to be connected to the tire air nozzle; the deflation device 30 is arranged on the first tube body 10, and when the deflation device 30 is opened, the first tube body 10 is connected to the outside. It can be seen that by means of the deflation device 30 provided on the first tube body 10, the tire can be deflated when connected to the tire without removing the quick-release air nozzle. On the other hand, the tire pressure detection function of the inflation equipment can detect the tire pressure in real time, so that the amount of air pressure that has been deflated can be accurately known.

[0038] Further, in certain embodiments, such as the present embodiment, the deflation device 30 includes an inlay 31, a button 32, a first sealing ring 33, a second sealing ring 34 and an elastic member 35, the inlay 31 includes a through hole 311, and an inlay hole 12 is provided on the side wall of the first tube body 10; the inlay 31 is embedded in the inlay hole 12, and the first sealing ring 33 is arranged between the inlay 31 and the side wall of the first tube body 10; one end of the button 32 passes through the through hole 311 into the first tube body 10, and the second sealing ring 34 is arranged between the button 32 and the inlay 31; the elastic member 35 abuts between the button 32 and the inner wall of the first tube body 10.

[0039] Specifically, the button 32 is cylindrical. The first sealing ring 33 can effectively seal the gap between the inlay 31 and the inlay hole 12 to prevent air leakage. The second sealing ring 34 can effectively seal the gap between the button 32 and the inlay 31 to prevent air leakage. The elastic member 35 is used to provide resilience.

[0040] Working principle: When the button 32 is pressed, the button 32 and the inlay 31 loosen the second sealing ring 34, and the gas can flow to the outside from the gap between the button 32 and the inlay 31 (at this time, the first tube 10 is connected to the outside through the gap between the button 32 and the inlay 31), thereby achieving air release. After the button 32 is released, the elastic member 35 rebounds, so that the button 32 and the inlay 31 clamp the second sealing ring 34, achieving reliable sealing and preventing air leakage.

[0041] Further, the inlay 31 is provided with a first pressing ear 312 protruding from the side, the inlay 31 passes through the first sealing ring 33, and the first sealing ring 33 is sandwiched between the first pressing ear 312 and the side wall of the first tube body 10. Specifically, the first pressing ear 312 can be provided at the upper end of the inlay 31, and at the same time, the surface of the first tube body 10 is provided with a step surface corresponding to the first pressing ear 312, and the first sealing ring 33 is sandwiched between the first pressing ear 312 and the step surface.

[0042] Furthermore, the button 32 is provided with a second pressing ear portion 321 protruding from the side, the button 32 passes through the second sealing ring 34 , and the second sealing ring 34 is sandwiched between the second pressing ear portion 321 and the inlay 31 .

[0043] Specifically, the second pressing ear 321 can be arranged at the lower end of the button 32, the upper end of the button 32 passes through the through hole 311 of the inlay 31, the diameter of the second pressing ear 321 is larger than the diameter of the through hole 311 of the inlay 31, and the second sealing ring 34 is clamped between the second pressing ear 321 and the bottom end of the inlay 31.

[0044] Furthermore, the inner wall of the first tube body 10 is provided with a receiving groove 13, and one end of the elastic member 35 is arranged in the receiving groove 13. The receiving groove 13 can facilitate the flow of gas when inflating.

[0045] Furthermore, the inlay 31 is threadedly connected to the inlay hole 12. Specifically, the inlay 31 can be a screw with a through hole 311, with an outer thread on the outer side and an inner thread on the inner side of the inlay hole 12, which can greatly improve the efficiency of installation and disassembly through the threaded connection.

[0046] Furthermore, the quick-release air nozzle with deflation function also includes a handle 40, and the handle 40 includes an extrusion end 41. The extrusion end 41 of the handle 40 is embedded in the notch end 22 of the second tube body 20 along the support portion 221, and the extrusion end 41 of the handle 40 is located on one side of the engaging end 14 of the first tube body 10, and the handle 40 is rotatably connected to the second tube body 20.

[0047] Specifically, the extrusion end 41 includes an outer protrusion 411 protruding outward, and the extrusion end 41 of the handle 40 is rotatably connected to the second tube body 20, and the rotation shaft 60 can be passed through the extrusion end 41 and the second tube body 20, so as to realize the rotation connection between the extrusion end 41 and the second tube body 20. During the rotation process, the outer protrusion 411 of the extrusion end 41 can be used to squeeze the fitting end 14 of the first tube body 10.

[0048] Furthermore, the quick-release air nozzle with deflation function also includes a soft rubber ring 50 , a support portion 211 is provided on the inner side of the air nozzle connecting end 21 of the second tube body 20 , and the soft rubber ring 50 is provided between the support portion 211 and the mating end 14 of the first tube body 10 .

[0049] The quick-release air nozzle with air release function of the utility model has three use states:

[0050] State 1: When the handle 40 is rotated to the preset first position, the soft rubber ring 50 is not squeezed by the fitting end 14 of the first tube body 10. Specifically, the first position may be a position where the handle 40 is parallel to the second tube body 20, at which time the squeezing end 41 of the handle 40 does not squeeze the fitting end 14 of the first tube body 10, and accordingly, the fitting end 14 of the first tube body 10 does not squeeze the soft rubber ring 50, and the soft rubber ring 50 is not deformed, so it is convenient to connect / disconnect the quick-release air nozzle with the deflation function with the air nozzle of the tire.

[0051] State 2: When the handle 40 rotates to the preset second position, the squeezing end 41 of the handle 40 squeezes the fitting end 14 of the first tube 10, so that the fitting end 14 of the first tube 10 squeezes the soft rubber ring 50. Specifically, the first position may be a position where the handle 40 is parallel to the first tube 10, at which time the squeezing end 41 of the handle 40 squeezes the fitting end 14 of the first tube 10, and correspondingly, the fitting end 14 of the first tube 10 squeezes the soft rubber ring 50, and the soft rubber ring 50 is compressed and deformed, and its inner diameter is reduced, so that the tire valve can be clamped to achieve sealing and avoid air leakage during inflation.

[0052] State 3, when the handle 40 rotates to the preset third position, the extrusion end 41 of the handle 40 squeezes the fitting end 14 of the first tube body 10, so that the fitting end 14 of the first tube body 10 squeezes the soft rubber ring 50, and the handle 40 presses the button 32 of the deflation device 30. Specifically, the third position may be the position where the handle 40 presses the button 32 of the deflation device 30 downward, and at this time, the angle between the handle 40 and the first tube body 10 may be 15°, which is specifically determined by the pressing height of the button 32, and is not specifically limited by the utility model. At this time, the extrusion end 41 of the handle 40 squeezes the fitting end 14 of the first tube body 10, and accordingly, the fitting end 14 of the first tube body 10 squeezes the soft rubber ring 50, and the soft rubber ring 50 is compressed and deformed, and its inner diameter is reduced, so that it can clamp the tire valve to achieve sealing. At the same time, since the handle 40 presses the button 32 of the deflation device 30 downward, the deflation device 30 can deflate the tire.

[0053] It can be understood that in the embodiment of the utility model, when the handle 40 is rotated to be parallel to the first tube body 10 (second position), the button 32 of the deflation device 30 is just below the handle 40, so that the button 32 of the deflation device 30 can be pressed by rotating the handle 40 downward again.

[0054] Furthermore, the elastic member 35 is a spring. One end of the elastic member 35 can be embedded in the inner wall of the first tube body 10, so as to achieve a reliable connection.

[0055] Furthermore, the outer side of the inflation connection end 11 of the first tube body 10 may be provided with an external thread, and may be threadedly connected to the inflation device, thereby improving the disassembly and assembly efficiency.
