Through the cooperation of the adjusting mechanism, the elastic mechanism and the thermal expansion body 41, the temperature of the liquid is accurately adjusted to the selected gear.
In addition, the mechanical temperature adjustment is not limited by power failure, even if the power failure occurs, the gear position selected by the slide block 21 is not changed, the thermal expansion body 41 contracts along with the gradual reduction of the liquid temperature, the elastic mechanism can drive the second terminal 12 to be in contact with the first terminal 11, and after the power is re-energized, the heating circuit can be conducted for heating, so that the liquid temperature is adjusted to the selected gear position.
The adjusting mechanism comprises a gear knob 22 and a transmission component connected with the gear knob 22, and the gear knob 22 can drive the sliding block 21 to move through the transmission component. The gear knob 22 can indicate a plurality of gears, a dial 23 is fixedly arranged on the periphery of the gear knob 22, and the dial 23 is annular and is sleeved on the periphery of the gear knob 22. The dial 23 is provided with a plurality of scales corresponding to the shift positions. The gear knob 22 can rotate around its own axis, and the gear knob 22 is provided with an indication key, and the scale indicated by the indication key is the gear selected by the gear knob 22.

In the process of rotating the gear knob 22, the sliding block 21 can be driven to move through the transmission assembly, and when the gear knob 22 is fixed at the selected gear, the sliding block 21 is fixed at the corresponding linear position. If the temperature of the liquid is lower than the selected gear, the second terminal 12 can be abutted with the first terminal 11 under the driving of the elastic mechanism, and the heating circuit is conducted to heat the liquid; during the heating process, the thermal expansion body 41 can be abutted with the slide block 21 by thermal expansion, and when the temperature of the liquid reaches the selected gear, the thermal expansion body 41 controls the heating circuit to be cut off. If the liquid temperature is not lower than the selected gear, the second terminal 12 cannot abut against the first terminal 11 due to the driving force of the thermal expansion body 41 in the opposite direction to the elastic structure, and the heating circuit is not conducted.
In the present embodiment, the elastic mechanism includes an elastic rod 311, one end of the elastic rod 311 is fixed, and the other end of the elastic rod 311 is provided with an abutting block 312, and the abutting block 312 can selectively abut against the second terminal 12. The elastic rod 311 can drive the abutting block 312 to abut against the second terminal 12 by its own elastic force, and the abutting force can make the second terminal 12 and the first terminal 11 well contact with each other.
The thermal expansion body 41 is located at one side of the elastic rod 311 and connected with the shaft of the elastic rod 311 so as to drive the elastic rod 311 to move. In the process of thermal expansion of the thermal expansion body 41, the thermal expansion body first abuts against the slider 21, and further, the displacement generated by the thermal expansion of the thermal expansion body 41 drives the elastic mechanism in the opposite direction.
After the liquid is heated, if the power is suddenly cut off or the heat preservation effect is poor, the temperature of the liquid gradually drops, the thermal expansion body 41 gradually shrinks, and the abutting block 312 moves under the action of the elastic rod 311, so that the second terminal 12 is close to the first terminal 11. When the thermal expansion body 41 is shrunk to a certain extent, the second terminal 12 is in contact with the first terminal 11.

The thermal expansion body 41 is positioned on one side of the moving block 322, and the thermal expansion body 41 can be connected with the moving block 322 so as to drive the moving block 322 to move in the opposite direction. In the process of thermal expansion of the thermal expansion body 41, the thermal expansion body first abuts against the slider 21, and further, the displacement generated by the thermal expansion of the thermal expansion body 41 drives the moving block 322 in the opposite direction. When the thermal expansion body 41 contracts upon cooling, the moving block 322 is restored by the spring 321.
In order to ensure the stability of the movement of the moving block 322, a slide rail 323 is arranged on one side of the spring 321, the slide rail 323 and the spring 321 extend in the same direction, and the moving block 322 is slidably connected with the slide rail 323.

At this time, if the elastic mechanism can drive the second terminal 12 to abut against the first terminal 11, indicating that the liquid temperature is lower than the temperature corresponding to the selected shift position, the heating circuit is turned on. If the shift knob 22 drives the sliding block 21 to move to a certain linear position during rotation, the heating circuit cannot be conducted, which indicates that the temperature of the liquid is not lower than the temperature corresponding to the selected shift, i.e. the shift knob 22 drives the sliding block 21 to move towards the thermal expansion body 41 during rotation.
