[0022] As Figure 1 shown, an energy-saving electric heating device includes a housing 1 and a heating assembly 2 fixedly connected inside the housing 1. The heating assembly 2 is used to heat the air inside the housing 1. It also includes a circulation assembly 3 fixedly connected inside the housing 1. The circulation assembly 3 is used to achieve the convection of hot air. A thermal sensing assembly 4 is provided inside the housing 1.

[0023] As Figures 2 - 3 shown in Fig. -4, the heating assembly 2 includes a first partition 5, a second partition 6, a heating plate 7 and a radiation plate 8. The first partition 5 is fixedly connected inside the housing 1, the second partition 6 is fixedly connected inside the housing 1. A closed heating chamber 9 is formed between the first partition 5 and the second partition 6. The heating plate 7 is fixedly connected to the rear side of the heating chamber 9, and the radiation plate 8 is fixedly connected to the front side of the heating chamber 9.

[0024] As Figure 3 shown, the circulation assembly 3 includes a pressurizing chamber 10 and an intake pipe 11. A closed return cavity 12 is formed between the first partition 5 and the upper side inside the housing 1, and a closed blowing cavity 13 is formed between the second partition 6 and the lower side inside the housing 1. The pressurizing chamber 10 is fixedly connected to the front side of the blowing cavity 13. The intake pipe 11 is arranged at the right end of the blowing cavity 13. The intake pipe 11 and the pressurizing chamber 10 are connected by a conduit. A through hole 14 is provided between the return cavity 12 and the blowing cavity 13.

[0025] Among them, the thermal sensing assembly 4 includes a thermistor 15 and a solenoid valve 16. The thermistor 15 is fixedly connected to the outside of the housing 1, the solenoid valve 16 is fixedly connected inside the blowing cavity 13. The thermistor 15 and the solenoid valve 16 are connected by a wire. The solenoid valve 16 and the heating plate 7 are connected by a wire. A worm gear motor is provided inside the intake pipe 11. The solenoid valve 16 and the worm gear motor are connected by a wire. Water is filled in the heating chamber 9. A water inlet 17 is provided on the left side of the heating chamber 9, and a water outlet 18 is provided on the left side of the heating chamber 9. The water inlet 17 is higher than the water outlet 18. The heating chamber communicates with the blowing cavity 13 and the outside of the housing 1. The through hole 14 communicates the return cavity 12 and the blowing cavity 13.

[0026] During specific use, first, water is filled into the heating chamber 9 through the water inlet 17, and the thermistor 15 is set. When the temperature is relatively low, due to the low temperature, the resistance of the thermistor 15 is small, the current in the circuit increases, the solenoid valve 16 is controlled, the solenoid valve 16 closes the circuit of the heater, and the heater heats the water in the heating chamber 9. The radiation plate 8 on the front side of the heating chamber 9 radiates the heat carried by the water in the heating chamber 9 to the outside.

[0027] When the temperature continues to decrease, the resistance of the thermistor 15 decreases accordingly, the current in the circuit increases accordingly, the solenoid valve 16 is controlled, the solenoid valve 16 closes the circuit of the worm gear motor, the worm gear motor adds gas into the pressurizing chamber 10, the gas is pressurized in the pressurizing chamber 10 and then discharged outside the housing 1. The pressure outside the pressurizing chamber 10 decreases, and due to the increase in the pressure difference, the gas is pressed into the return chamber 12, heated through the through hole 14 and then enters the blowing chamber 13 and is discharged outside the housing 1.

[0028] By combining radiation and convection, the heating effect is improved, the waste heat generated during the heating process is reused, and the energy utilization efficiency is increased. Through the linkage of the thermistor 15, the solenoid valve 16, the worm gear motor, and the heating plate 7, the functions of automatic temperature adjustment and timed switching are realized.
