Understandably, the fixed frame 15 can be a frame structure with an internal hollow formed by multiple bending of a plate-shaped material (such as a metal plate). After bending, the internal hollow area is the installation space 150, and at least part of the movable switch 141 is located in the installation space 150, so that the movable switch 141 moves in the installation space 150, the driving member 142 is installed outside the installation space 150 and connected with the movable switch 141 through the fixed frame 15 to drive the movable switch 141 to move in the installation space 150. Under this arrangement, the compactness of the overall structure of the switch device 14 is improved. Moreover, the fixed frame 15 can limit the maximum range of rotation of the movable switch 141, improving the reliability of the movable switch 141 in opening or closing the communication pipe 13.
