The connecting mechanism 4 also includes a connecting plate 404. A baffle 402 is fixedly provided on the inner side of the connecting pipe 401. A connecting port 403 is provided on the baffle 402. The connecting plate 404 and the baffle 402 are rotatably connected to the side of the sealing tank 303 to ensure the one-way opening of the connecting pipe 401. A groove 405 is provided on the side of the connecting port 403 close to the sealing tank 303. A sealing rubber plate 406 is fixedly provided on the side of the connecting plate 404 close to the sealing tank 303. The sealing rubber plate 406 and the groove 405 are in a chiming connection to ensure the sealing of the connecting plate 404 when it is closed.

[0021] like Figure 1 and Figure 2 As shown, an air inlet pipe 5 is fixedly provided on the upper side of the insulation tank 301, and one end of the air inlet pipe 5 is connected to the insulation tank 301, and a connecting bolt 501 is provided on the air inlet pipe 5 for connecting to the ammonia storage tank. A drain pipe 6 is fixedly provided on the lower side of the sealed tank 303, and one end of the drain pipe 6 is connected to the sealed tank 303, and a valve 601 is provided on the drain pipe 6 for discharging the collected ammonia water.
