[0034] Working principle:

[0035] When the automatic control device of the heating system is actually used, it is powered on. When the temperature sensor detects that the temperature inside the tank body 1 is low, it can send a signal to the controller, and the controller makes the electric heater work. The electric collector can heat the water inside the tank body 1, and the water can be discharged through the liquid outlet pipe 9 to perform heating work. When the time reaches the preset value of the timer, it will send a signal to the controller, and the controller makes the first solenoid valve 14, the first solenoid valve 14 and the pump 5 work. The water inside the tank body 1 can pass through the sewage pipe 2, the liquid pumping pipe 4 and the three-way pipe 6. When the water passes through one end of the three-way pipe 6, the left group of impellers 13 can rotate, and the left group of impellers 13 can rotate. The impellers 13 on the side can rotate the scraper frame 10 through the connecting shafts 12 on the left side. The rotating scraper frame 10 can scrape the inner wall of the tank body 1. When the preset value of the timer is reached again, a signal can be sent to the controller. The controller can close the second solenoid valve 15 and open and close the third solenoid valve 16 at the same time. The water passes through the other end of the three-way pipe 6. The flowing water can drive the impellers 13 on the right side to rotate in the opposite direction. The impellers 13 on the right side that rotate in the opposite direction can rotate the scraper frame 10 in the opposite direction through the connecting shafts 12 on the right side. When the scraper frame 10 rotates forward and reversely, the impurities sticking to the front and back surfaces of the scraper frame 10 can be washed away by the water. By setting the three-way pipe 6, the inner wall of the water storage space can be fully scraped, and the impurities on the surface of the cleaning structure can also be fully removed, thereby improving the practicality of the automatic control device of the heating system. At the same time, according to the above operation, when the timer reaches the preset value, a signal can be sent to the controller, and the controller can make the pump 5 work. The pump 5 can make the water inside the tank body 1 pass through the sewage pipe 2, the circulation pipe and the three-way pipe 6 to achieve the purpose of water circulation. In this process, the filter screen 21 can intercept impurities in the water. When the preset value of the timer is reached again, a signal can be sent to the controller again, and the controller can stop the pump 5, and the electric The electric telescopic rod 19 and the electric heating plate 7 work, and the fourth solenoid valve 18 opens and closes at the same time. The electric telescopic rod 19 can move the pressing plate 20 downward, and the pressing plate 20 and the electric heating plate 7 can squeeze the impurities inside the cleaning box 3.
