[0025] It should be noted that there are multiple air ducts 7, and the diameters of the air duct connectors 8 connected to different end faces of the air ducts 7 are all different. Before the airtightness detection of the ducts, first fill the inside of the water storage tank 1 with water liquid, then select the corresponding air duct connector 8 of the duct for plugging and fixing, and seal the end of the duct with an externally connected plug.

Start the air pump 4 through an externally connected control device to blow air into the ducts, and observe the state of the water bubbles on the liquid surface. If there are water bubbles in the water liquid, it means that the duct has poor airtightness and there is an air leakage phenomenon. If there are no water bubbles in the water liquid, it means that the duct has good airtightness and can be used normally.

[0026] Refer to Figure 1 and Figure 4 As shown, the water draining assembly includes a water draining frame 5. The water draining frame 5 is erected above the water storage tank 1. The end of the water draining frame 5 is movably connected to the water storage tank 1 through a self-locking shaft seat 11.

If there are no water bubbles in the water liquid, it means that the duct has good airtightness and can be used normally. The end of the water draining frame 5 is movably connected to the water storage tank 1 through a self-locking shaft seat 11, and a positioning groove 12 is formed on the surface of the water draining frame 5.
