When the boiler furnace 1 needs to be cleaned, the flip plate 143 can be turned over for cleaning through the motor A141, and after the cleaning is completed, the fireproof plate 147 is turned over again to close the circular slot 16.

[0027] A plate groove 171 and a rectangular groove 172 are provided on the upper surface of the storage plate 17, and a motor B173 is fixedly installed on one side of the storage plate 17. A driving rod B174 is fixedly installed on one side of the storage plate 17, and the driving rod B174 passes through one side of the plate groove 171. The outer surface of the driving rod B174 is sleeved with a first cleaning plate 18, and the first cleaning plate 18 can be turned out for cleaning by the driving rod B174, and then the first cleaning plate 18 can be stored.

[0028] A rod groove 181 is penetrated through one side of the first cleaning plate 18, and the rod groove 181 corresponds to the driving rod B174. A groove 182 is penetrated through one side of the first cleaning plate 18. A first brush pad 183 is fixedly installed on the other side of the first cleaning plate 18. A motor C184 is fixedly installed on one side of the first cleaning plate 18. A driving rod C185 is fixedly installed on one side of the motor C184, and the driving rod C185 passes through one side of the groove 182.

The water inside the water tank 21 is pumped into the water pipe 22 by the water pump 23 and then sprayed out by the nozzle 24.

[0032] Specifically, when it is necessary to clean the inside of the boiler furnace 1, it is only necessary to start the motor A141 first to turn the entire cleaning assembly 14 over. At the same time, the fireproof plate 147 will also turn over along the circular groove 16. At this time, the first cleaning plate 18 and the second cleaning plate 19 are in a vertical position in the incineration chamber 15, and then the electric telescopic rod 146 is started first. After the storage plate 17 is lifted to a suitable height, the motors B173 and C184 can be started in turn to let the first cleaning plate 18 slowly turn over and leave the plate groove 171. At this time, the second cleaning plate 19 also slowly turns out from the groove 182. Then, when the first cleaning plate 18 and the second cleaning plate 19 are in place, the motor D148 can be started to let the driving rod D149 rotate the storage plate 17. At this time, the first cleaning plate 18 and the second cleaning plate 19 are in place. Plate 18 and the second cleaning plate 19 will also rotate. When the motor D148 is started, the water pump 23 will pump the water inside the water tank 21 into the water pipe 22, and finally spray it out from the nozzle 24. After the water is sprayed out by the nozzle 24, the first brush pad 183 and the second brush pad 192 can be used to clean the inner wall of the boiler furnace 1.
