Preferably, the step of stabilizing the water pressure of the water inlet pipeline 1 by the operation of the water storage pressure device 4 is as follows:
when the water pressure of the water inlet pipeline 1 is increased, the water in the water inlet pipeline 1 flows into the water storage pressure device 4, specifically, when the water pressure of the water inlet pipeline 1 is increased, the water pressure of the water inlet pipeline 1 is greater than the water pressure in the water storage pressure device 4, due to the water pressure difference between the water inlet pipeline 1 and the water storage pressure device 4, the water in the water inlet pipeline 1 flows into the water storage pressure device 4 to balance the water pressures of the water inlet pipeline 1 and the water storage pressure device 4, and the water storage pressure device 4 can absorb the water pressure when the water pressure of the water inlet pipeline 1 is increased;

whether the current water pressure meets the combustion meeting requirements is judged according to the current water flow, and the method is specific:
if the current water pressure meets the combustion meeting the requirements, judging whether the current water pressure is the standard water pressure or not according to the current water flow;
if the current water pressure does not meet the combustion meeting requirements, the water regulating valve 2 is controlled to work to enable the current water pressure to meet the combustion meeting requirements, particularly, if the current water pressure does not meet the combustion meeting requirements, the controller is used for controlling the water regulating valve 2 to increase the opening degree to increase the current water flow, and then the current water pressure meets the combustion meeting requirements.
