specific Embodiment approach 3
[0021] Specific implementation mode three: combination figure 1 with Figure 7 To explain this embodiment, this embodiment also includes a pressure indicator 10, which is arranged in the tank body 1-1. The pressure indicator 10 is composed of a transparent tube 10-1 and a piston 10-2, and the piston 10-2 is arranged in the transparent tube. In 10-1, a scale is provided on the outer surface of the transparent tube 10-1. The tank body 1-1 can be made of plastic. The pressure indicator 10 is fixed in the tank body 1-1. After the tank body 1-1 is inflated, the pressure inside the tank body 1-1 increases, causing the piston 10-2 to move inward. Push forward, otherwise exit outward. The scale on the front of the piston is the pressure value in the tank. Others are the same as the first or second embodiment.
