[0028] Working principle of the present invention: Step 1: During jet heating, the docking gas pipe 14 is docked with the gas pipeline, and the water inlet heat exchange pipe 17 is docked with the cold water inlet pipe, and the water outlet heat exchange pipe 18 is docked with the hot water outlet pipe. The gas is poured into the docking gas pipe 14, and the docking gas pipe 14 is docked with the air inlet pipe 13, and enters the inside of the jet pipe 15 along the air inlet pipe 13. The upper spraying operation is realized through the multiple jet holes 30 on the jet pipe 15.

[0029] Step 2: During the self-check of position change, the electric cylinder 2 pushes the push block 3 downward, the push block 3 drives the connecting block 4 downward, the connecting block 4 drives the reduction motor 5 to move the gear 6 downward, and at the same time, the push block 3 drives the linkage block 12 downward, the linkage block 12 drives the support block 11 downward, the support block 11 drives the positioning ring 9 downward, the positioning ring 9 drives the two limit rings 8 downward, the two limit rings 8 make the gear ring 7 move downward, and at the same time, the gear ring 7 drives the gas concentration sensor 10 downward, and the gas concentration sensor 10 is realized along the connection between the intake pipe 13 and the docking pipe 14.

After the gear ring 7 rotates 360 degrees in the forward direction, the gear ring 7 rotates 360 degrees in the reverse direction. In this way, the gear ring 7 drives the gas concentration sensor 10 to rotate back and forth. The gas concentration sensor 10 can perform gas detection along the connection between the air inlet pipe 13 and the docking air pipe 14.
