A mounting plate 13 is provided in the smoke outlet pipe 2, and the reciprocating screw 14 passes through the mounting plate 13 and is threadedly connected thereto. A cavity fixing plate 21 is fixedly installed on the bottom of the mounting plate 13, and a plurality of nozzles 22 are arranged at equal distances on the bottom of the fixing plate 21; slide grooves 15 are provided on both sides of the smoke outlet pipe 2, and matching protrusions 20 are installed on both sides of the mounting plate 13, and the protrusions 20 are located in the slide grooves 15; a diversion hose 3 is installed on the water tank 6, and the diversion hose 3 is connected to the fixing plate 21.
