The hot water can provide a heat source for buildings to heat them, and can also be discharged as domestic water for bathing, etc.

[0003] A variety of gas heating hot water boilers have been proposed in the prior art, such as the gas heating hot water boiler proposed in the Chinese utility model patent with application number CN202021610634.6, which includes a first heat exchanger, a first water inlet pipe and a first water outlet pipe. The water inlet and the water outlet of the first heat exchanger are respectively connected to the first water inlet pipe and the first water outlet pipe. A water flow detector is provided on the first water inlet pipe, and a first booster pump is installed on the first water outlet pipe. The controller controls the working state of the first booster pump according to the water flow of the first water inlet pipe detected by the flow detector, and pressurizes the domestic hot water discharged from the first water outlet pipe to accelerate the discharge of domestic hot water, avoid the problem of the burner failing to start normally or the domestic hot water overheating due to too low water flow, broaden the flow range of domestic hot water of the gas heating hot water boiler, improve water use comfort, and thereby improve user experience.

[0004] Since the gas in the gas heating furnace will produce carbon black during ignition and low-power combustion, the carbon black will form carbon deposits in the combustion chamber or heat exchanger.

[0023] The combustion head of the burner 3 ignites to form a flame, and the combustion generates heat to heat the water in the water exchange jacket 4. The circulating pump on the water exchange jacket 4 pumps out the hot water, and the cold water returns to form a cycle to achieve the purpose of heating; the flame is gathered by the adsorption bucket 6, and the water in the water exchange jacket 4 forms a circulation flow with the adsorption bucket 6 through two water pipes 10, so that the adsorption bucket 6 gathers the flame and heats the water in the adsorption bucket 6, thereby cooling and protecting the adsorption bucket 6. The carbon black formed when the gas is burned first contacts the inner wall of the adsorption bucket 6, so that most of the carbon black is deposited on the inner wall of the adsorption bucket 6, and a small part of the carbon black is discharged through the exhaust pipe 5 along with other flue gases, and the flue gas When passing through the smoke exhaust pipe 5, the impeller 8 is driven to rotate, and the impeller 8 drives the rotating shaft 7 to rotate, and the rotating shaft 7 drives multiple scrapers 9 to rotate, so that the multiple scrapers 9 scrape off the carbon black attached to the inner wall of the adsorption bucket 6.

At the same time, when the pull rod 14 is pulled to discharge the carbon black lumps, the contact switch 19 is triggered. The electrical signal generated by the contact switch 19 controls the action of the electromagnetic pin 18, so that the piston rod of the electromagnetic pin 18 is extended to stop the rotation of the rotating shaft 7 and the impeller 8, so that the internal air pressure of the combustion chamber 2 increases. The higher air pressure forms an airflow to blow the carbon black lumps on the bottom plate 11 into the cloth belt 15 for discharge.
