[0002] In modern industrial production, inflatable equipment is widely used in various fields, such as tire manufacturing, gas compression, and pneumatic tools. An inflatable device is a device that can fill gas into the inflatable device and control and adjust the working state of the inflatable device. In the prior art, the inflatable device decompresses the high-pressure gas source to obtain a gas pressure that meets the use requirements, and then fills the gas into the inflatable device. Existing inflatable devices cannot adjust the inflation pressure after decompressing the high-pressure gas source and can only inflate inflatable devices with a single pressure. This device cannot meet the needs of inflatable devices with multiple different inflation pressures, resulting in a narrow scope of application and low production efficiency. Utility Model Content

Compared with the prior art, the inflation pressure of the inflation device cannot be adjusted, and the needs of inflatable devices with a variety of different inflation pressures cannot be met. The scope of application is narrow, resulting in low production efficiency. The utility model can adjust the inflation pressure through the controller, which can meet the needs of inflatable devices with a variety of different inflation pressures. It has a wide range of applications and greatly improves production efficiency.
