Working principle: Before use, check whether the lines and pipelines are normal, turn on the power and set the required temperature, the high-temperature fireworks generated in the combustion chamber 19 first enter the heat exchange chamber 17 connected to it, and then pass through the heat exchange chamber 17 and the smoke stringing hole 36 between the preheating chamber 3 enters the first stringing smoke pipe 35 in the preheating chamber, because the first stringing smoke pipe 35, the second stringing smoke pipe 34 and the third stringing smoke pipe 30 are connected to each other, and the high-temperature pyrotechnics will rotate in the preheating chamber 3 so as to prolong the motion time of the pyrotechnics to the greatest extent, thereby improving the heat exchange rate. The exhaust pipe 2 of the fan 1 is discharged; the water first enters the automatic water supply pressure tank 11 through the water inlet pipe 15, and then enters the first water interlayer 31 in the preheating chamber 3 through the water inlet pipe 4 on the top of the preheating chamber 3 , because the first water interlayer 31, the second water interlayer 32 and the water interlayer 33 at the heat exchange chamber are connected to each other, the water in the water interlayer will absorb the heat of the high-temperature pyrotechnics in the string pipe, thereby increasing the water temperature in the water interlayer, No waste of heat, so as to enter the water interlayer 37 of the heat exchange chamber 17 for further heating; the water in the water interlayer 33 of the preheating chamber passes through the guide tube 5 after preheating, and the water interlayer 37 of the outer wall of the heat exchange chamber and the combustion chamber respectively The outer wall water interlayer 38 is connected, and the inclined heat exchange coil 40 can absorb a large amount of heat, and can make the water in the water interlayer circulate and exchange heat with each other, because the heat exchange outer wall water interlayer 37 and the combustion outer wall water interlayer 38 are passed through The water series pipes 42 outside the furnace body communicate with each other, so that the water flow rate of the water interlayer 37 on the outer wall of the heat exchange and the water interlayer 38 on the outer wall of the combustion chamber slow down, prolonging the time of water retention, thereby further improving the heat exchange efficiency; the water interlayer on the outer wall of the heat exchange 37 and one side of the outer wall water interlayer 38 of the combustion chamber are respectively provided with a hot water outlet pipe 28 and a heating outlet pipe 23, so that the water in the furnace body is used for heating and bathing respectively; 10 and 14 are controlled by an electronic controller. When heating and hot water are used at the same time, the electronic controller opens the valves 7 and 8, and the water in the water interlayer 33 of the preheating chamber 3 enters the water interlayer 37 of the outer wall of the heat exchange and burns The outdoor wall water interlayer 38 is discharged and used through the hot water outlet pipe 28 and the heating outlet pipe 23; the hot water outlet pipe 28 guides the hot water into the hot water storage tank 29 for standby, and the heating outlet pipe 23 passes through the radiator through the heating circulation pump 25 After dissipating heat, it circulates through the pipeline into the water interlayer 38 on the outer wall of the combustion chamber or enters the first water interlayer 31 in the preheating chamber 3 through the pipeline for recycling; when hot water is supplied alone, the valves 7, 9, 16, 26 are closed, and 8, 10, and 14 are turned on, the water in the water interlayer on the outer wall of the preheating chamber 3 enters the water interlayer 38 on the outer wall of the combustion chamber 19 through the valve 8, and enters the water interlayer 37 on the outer wall of the heat exchange chamber 17 through the water series pipe 42 after heat exchange, and then passes through The hot water outlet pipe 28 is used for discharge; when heating alone, the valves 7, 9, 10, 14, 26 are opened, the valves 8, 16 are closed, and the water in the water interlayer 33 on the outer wall of the preheating chamber 3 enters the outer wall of the heat exchange chamber 17 through the valve 7 Heat absorption in the water interlayer 37, after passing through The string water pipe 42 enters the water interlayer 38 on the outer wall of the combustion chamber 19 to absorb heat again, and the heating outlet pipe 23 with the heating circulation pump 25 enters the heat sink for heat dissipation and heating, and then enters the first heating chamber in the preheating chamber 3 through the pipe with the valve 9 A water interlayer 31, and preheating in the preheating chamber 3, and then enter the water interlayer 37 on the outer wall of the heat exchange chamber 17 through the valve 7 for repeated cycle heat absorption; during operation, the temperature sensing probes 41, 43 can be Real-time monitoring of the temperature of the water and the temperature of the furnace body. When the temperature is too high, the electronic controller can reduce the water temperature by increasing the intake of cold water, and can also adjust the running pipeline of water in the furnace body by controlling the opening and closing states of different valves. Thereby adjusting the temperature of the water; at the same time, the required temperature can also be set, and the fan speed can be adjusted through the electronic controller 13, so as to adjust the temperature with the air volume; The water interlayer on the outer wall and the water interlayer on the outer wall of the combustion chamber 22, 27 and the sewage pipe 21 discharge the scale, so as to keep the circulation in the water interlayer smooth, the water quality clean, and prevent clogging; the waste residue generated during combustion can pass through The air inlet 20 and the upper and lower parts of the preheating chamber are connected to the dust removal port 6 of the series smoke pipe to discharge.

The heat exchange chamber and the combustion chamber of the present invention are connected to each other, but the water interlayer on the outer wall of the heat exchange and the water interlayer on the outer wall of the combustion chamber are not connected to each other, but are connected to each other through the water series pipes outside the furnace body, thereby prolonging the flow of water in the furnace body time, slow down the flow speed, increase heat transfer efficiency, and improve energy utilization; moreover, the flow of water can be adjusted by opening and closing the valve, so as to adjust individual heating or hot water supply, and can also provide heating and hot water at the same time; The controller can easily adjust the water temperature and air supply volume, and the temperature sensor can detect the change of water temperature, so as to adjust the opening and closing of the valve and the intake of cold water, and control the water temperature in the furnace at a constant temperature, which is safe and reliable.
