[0022] Two pipes 2 are connected in the box body 1, and a filter screen 17 is fixedly connected to the inner side of the pipe 2. A flow guide pipe 18 is connected between the two pipes 2. The filter screen 17 provides a filtering point for impurities in the gas to improve the purity of the gas flow, and the flow guide pipe 18 provides additional flow space for the gas between the two pipes 2, thereby effectively reducing the pressure caused by the gas.

[0023] The two pipes 2 are respectively fixedly connected with flanges 3 on the outside, a first sealing ring 13 is fixedly connected to one side of the flange 3, a slot 14 is provided in the first sealing ring 13, a second sealing ring 15 is fixedly connected to one side of the flange 3, and four mounting holes 16 are provided in the two flanges 3, so that the second sealing ring 15 can be inserted into the slot 14 to achieve the fitting work between the first sealing ring 13, so as to achieve the purpose of the first sealing ring 13 and the second sealing ring 15 can seal the connection between the two pipes 2;
