Referring to fig. 4, a water inlet 41 and a water outlet 42 are formed in the battery pack 4, a flow channel 43 is formed in the battery pack 4, one end of the flow channel 43 is communicated with the water inlet 41, and the other end is communicated with the water outlet 42; the water inlet 41 is communicated with the water tank 3 through a water pipe, and the water outlet 42 is communicated with the water pump 1 through a water pipe. When the water pump 1 pumps water, water in the water tank 3 enters the flow channel 43 from the water inlet 41, partial heat on the surface of the battery is taken away through water flow, the water flow preheated by the battery pack 4 flows out through the water outlet 42, is pumped into the boiler 2 through the water pump 1, is converted into high-temperature steam through the boiler 2, and is sprayed out through the nozzle 5.

When water is sprayed into the boiler 2, the temperature of the water in the boiler 2 is reduced, and when the temperature in the boiler 2 is lower than a first preset temperature or higher than a second preset temperature, the first temperature control switch 62 controls the battery pack 4 to supply power to the boiler 2, and the electric heating tube in the boiler 2 starts to heat again; at this time, the second temperature-controlled switch 63 controls the motor of the water pump 1 to pump water at the second rotation speed (lower rotation speed); the first rotational speed is greater than the second rotational speed. The water spraying speed is slowed down to achieve the effect that the nozzle 5 sprays steam stably. Specifically, the second preset temperature is a temperature at which the boiler 2 can slowly convert water sprayed into the boiler 2 into high-temperature steam at a constant speed. (for example, when the pressure of the outlet steam inside the boiler 2 is specified to be 13.7MPa, the second preset temperature is 400 deg.C.)
