[0034] The present invention is further described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0035] According to one embodiment of the utility model, Figures 1 to 5 , a gas valve, comprising:

[0036] A valve body shell 1, one side of which is provided with an opening, and the valve body shell 1 is provided with a plurality of air pipes communicating with the inside and outside of the shell;

[0037] A valve cover 2, the valve cover 2 is combined with the opening of the valve body shell 1, and a pressure relief hole 5 is opened on the valve cover 2;

[0038] An elastic valve core 3, wherein the elastic valve core 3 is arranged inside the valve body shell 1, one end of the elastic valve core 3 is supported on the bottom of the valve body shell 1, and the other end passes through the pressure relief hole 5 and is located outside the valve body shell 1;

[0039] The elastic valve core 3 blocks the pressure relief hole 5 under the action of elastic force; when the end of the elastic valve core 3 located outside the valve body shell 1 moves toward the inside of the valve body shell 1, the blocking state of the pressure relief hole 5 is released.

[0040] In order to promote the application of air pressure adsorption technology in the field of mobile phone adsorption charging, the inventor of the utility model designed an air valve, which includes a valve body shell 1, a valve cover 2 and an elastic valve core 3. In this embodiment, the valve body shell 1 is provided with three air pipes connecting the inside and outside of the shell, which are respectively an air inlet pipe 6, an exhaust pipe 7 and a detection pipe 8.

[0041] The air inlet pipe 6 can be directly or indirectly connected to the suction cup for adsorbing the mobile phone, the exhaust pipe 7 is connected to the exhaust device, such as a vacuum pump, and the detection tube 8 is connected to an air pressure sensor. When the mobile phone needs to be adsorbed, the vacuum pump works to suck out the gas from the suction cup and the gas in the air valve, so that the whole forms a negative pressure, and the mobile phone can be adsorbed by the suction cup. The air pressure sensor is used to detect the air pressure inside the valve body, and indirectly obtain information on whether the mobile phone can be firmly adsorbed. The signal detected by the sensor can be used as a feedback signal to control the vacuum pump, and the size of the adsorption force is adjusted in time to ensure that the mobile phone can be stably adsorbed.

[0042] In this embodiment, the elastic valve core 3 is used as a pressure relief component. Initially, the elastic valve core 3 blocks the pressure relief hole 5 on the valve cover 2 under the action of elastic force; when pressure relief is required, the user only needs to push the elastic valve core 3 along the direction inside the valve body shell 1, and the pressure relief hole 5 will open, so that the entire air path is connected to the atmospheric pressure, unloading the adsorption force, so that the user can easily remove the mobile phone from the suction cup. The air valve of the utility model has a simple structure and can realize rapid unloading of air pressure, which promotes the development of air pressure adsorption technology in the field of mobile phone adsorption charging.

[0043] According to an embodiment of the utility model, the valve body shell 1 is a hexahedron with a single-sided opening, the air inlet pipe 6 and the exhaust pipe 7 are arranged on the same plane, and the detection pipe 8 is arranged on a different plane from the air inlet pipe 6. By arranging the air inlet pipe 6 and the exhaust pipe 7 on the same plane, the length of the air path is shortened, which is conducive to the rapid adsorption of the mobile phone.

[0044] According to an embodiment of the utility model, a first sealing rubber ring 4 is provided at the joint between the valve cover 2 and the valve body shell 1. The valve cover 2 is provided with a plurality of through holes 9, and the valve body shell 1 is provided with threaded holes corresponding to the through holes 9. The air tightness of the gas valve after the valve cover 2 and the valve body shell 1 are combined is ensured by threaded connection and the first sealing rubber ring 4.

[0045] Further, such as Figure 3As shown, in this embodiment, the valve cover 2 includes a covering portion 11 located outside the valve body shell 1 and an embedded portion 10 located inside the valve body shell 1. An annular groove 12 is provided at the opening of the valve body shell 1, and the embedded portion 10 of the valve body shell 1 presses the first sealing rubber ring 4 into the annular groove 12. By providing the embedded portion 10 extending into the interior of the valve body shell 1 on the valve cover 2, the first sealing rubber ring 4 is pressed into the annular groove 12 provided at the opening of the valve body shell 1 by means of the embedded portion 10, and the air tightness of the gas valve after the valve cover 2 and the valve body shell 1 are combined is further improved.

[0046] According to one embodiment of the utility model, Figure 5 As shown, the elastic valve core 3 includes a spring 14 arranged inside the valve body shell 1, and a partially raised blocking rod 15. Under the action of the spring 14, the raised portion of the blocking rod 15 is held against the inner side of the valve cover 2 to block the pressure relief hole 5. A second sealing rubber ring 16 is also arranged between the raised portion of the blocking rod 15 and the inner side of the valve cover 2. A spring seat 13 is arranged at the bottom of the valve body shell 1. One end of the spring 14 is arranged in the spring seat 13, and the other end is sleeved on the blocking rod 15 and held against the raised portion of the blocking rod 15. In this embodiment, the valve body shell 1 and the valve body cover are both integrally formed components. A spring seat 13 is formed on the bottom of the valve body shell 1, and a spring 14 of the elastic valve core 3 is arranged in the spring seat 13. When the pressure is not relieved, the sealing rod 15 blocks the pressure relief hole 5 on the valve cover 2 under the action of the elastic force of the spring 14, and the second sealing rubber ring 16 is pressed tightly against the pressure relief hole 5 on the inner side of the valve cover 2. Since the sealing rod 15 is partially raised, one side of the raised part can be combined with the spring 14 to receive the elastic force, and the other side can be combined with the pressure relief hole 5 to achieve the blocking of the pressure relief hole 5.

[0047] In this embodiment, by providing a second sealing rubber ring 16, it is ensured that the sealing rod 15 can completely block the pressure relief hole 5 in the initial state. When the sealing rod 15 is subjected to axial force, the spring 14 is compressed and the pressure relief hole 5 is opened to unload the air pressure. When the external force disappears, the sealing rod 15 can block the pressure relief hole 5 under the action of elastic force to ensure the normal operation of the valve body.
