[0023] like Figures 1 to 4 As shown, the embodiment of the present utility model proposes an electric heating steam generator, including a box body 1, a steam generating device 2 is installed inside the box body 1, a partition 3 is fixedly connected to the inner wall of the box body 1, a water tank 4 is provided in the box body 1, the water tank 4 is located above the steam generating device 2, a water supply pipe 5 is connected between the water tank 4 and the steam generating device 2, one side of the water tank 4 is connected to a delivery pipe 6, a heat conduction device 7 is provided between the water tank 4 and the steam generating device 2, a fixed box 8 is fixedly connected between the box body 1 and the partition 3, the water tank 4 is located in the fixed box 8, the water tank 4 is fixedly connected to the fixed box 8, the water supply pipe 5 and the delivery pipe 6 both pass through the fixed box 8, the fixed box 8 is filled with heat transfer oil, and the water is passed through the fixed box 8. It enters the water tank 4 through the delivery pipe 6, and enters the steam generating device 2 through the water tank 4 through the water supply pipe 5. After being exposed to high temperature, the water forms steam and is discharged. When the steam generating device 2 is in use, a large amount of heat is generated, which can easily cause the temperature of the steam generating device 2 and the box body 1 to rise. At this time, the heat conducting device 7 conducts the heat inside the box body 1 and the surface of the steam generating device 2 into the fixed box 8, heating the heat conducting oil in the fixed box 8. The heat conducting oil heats the water in the water tank 4, causing the water temperature to rise. When the steam generating device 2 needs to be replenished with water, warm water enters the steam generating device 2, reducing the impact on the temperature inside the steam generating device 2, reducing the time for the steam generating device 2 to generate steam, and improving efficiency.

[0024] like Figure 2 and Figure 3As shown, the heat-conducting device 7 includes a mounting plate 71, which is fixedly connected to the fixed box 8. The mounting plate 71 passes through the fixed box 8. One side of the mounting plate 71 is fixedly connected to a heat-conducting rod 72. One end of the heat-conducting rod 72 is fixedly connected to a heat-conducting plate 73. The heat-conducting plate 73 is tightly attached to the outside of the steam generating device 2. The other end of the heat-conducting rod 72 passes through the mounting plate 71 and extends into the fixed box 8. The other end of the heat-conducting rod 72 is fixedly connected to a heat-conducting grille 74. The mounting plate 71 and the fixed box 8 are both made of thermal insulation material. The heat-conducting plate 73 contacts the outside of the steam generating device 2. The heat generated by the steam generating device 2 when in use is transferred to the heat-conducting grille 74 inside the fixed box 8 through the heat-conducting rod 72, and is then transferred to the heat-conducting oil through the heat-conducting grille 74 to heat the heat-conducting oil, thereby heating the heat-conducting oil and then heating the water in the water storage tank 4, saving energy. At the same time, the mounting plate and the fixed box 8 are both made of thermal insulation material to reduce heat loss.

The cross-section of the blocking block 17 is trapezoidal, and the side wall of the circular groove is a slope, which fits the side of the blocking block 17. A vent pipe is provided on one side of the water tank 4. When water enters the water tank 4, the servo motor 9 drives the threaded rod 10 to rotate, controls the extrusion plate 11 to move, and the water pushes the blocking block 17 to leave the circular groove on the support plate 14 and enter the water tank 4. After the water supply stops, the spring 18 pushes the blocking block 17 to block the support plate 14 to prevent water from flowing back. When replenishing water into the steam generating equipment 2, the servo motor 9 drives the threaded rod 10 to rotate in the opposite direction, and the extrusion plate 11 moves in the opposite direction, squeezing the internal water through the water supply pipe 5, through the shell 13, and pushing open the blocking block 17 in the shell 13 to enter the steam generating equipment 2 for water replenishment. The water supply pipe 5 is wrapped with thermal oil to prevent the water temperature from dropping during water replenishment.

[0026] Working principle: water enters the water tank 4 through the delivery pipe 6, and enters the steam generating device 2 through the water tank 4 through the water supply pipe 5. When the steam generating device 2 is in use, a large amount of heat is generated. The heat conducting plate 73 contacts the outside of the steam generating device 2, and the heat generated when the steam generating device 2 is in use is transferred to the heat conducting grid 74 inside the fixed box 8 through the heat conducting rod 72, and is transferred to the heat conducting oil through the heat conducting grid 74, heating the heat conducting oil, and then heating the water in the water tank 4. When replenishing water into the steam generating device 2, the servo motor 9 drives the threaded rod 10 to rotate in the opposite direction, and the extrusion plate 11 moves in the opposite direction, squeezing the inside through the water supply pipe 5, through the shell 13, and pushing open the blocking block 17 in the shell 13, and entering the steam generating device 2 for water replenishment.
