[0034] Furthermore, a protrusion is integrally formed at the front end of the L-shaped plate 240, and the protrusion is in movable contact with the bottom of the touch switch 280. The setting of the protrusion ensures that the L-shaped plate 240 can contact the touch switch 280, providing conditions for opening the solenoid valve.

[0035] Furthermore, the water outlet end of the water heater 250 is located at the top of the processing chamber 110 and communicates with the inside of the water cavity.

Then, by using the external PLC, the control of the present device can be made more convenient.

[0038] Embodiment 2:

[0039] Combined with Figure 1 、 3 and Figure 4As shown, on the basis of the first embodiment, a guide rod 400 is installed inside the table frame 210, and the L-shaped plate 240 is movably sleeved outside the guide rod 400. By providing the guide rod 400, the moving direction of the L-shaped plate 240 can be defined, enabling it to stably translate within the table frame 210.

[0040] Embodiment Three:

[0042] Working principle and usage process of the present utility model: When the device is put into actual use, a workpiece is placed on the bracket 130, and then the movable end of the external PLC-controlled cylinder 310 contracts, causing the top cover 120 to drive the bracket 130 and the workpiece to descend into the processing chamber 110. Meanwhile, the temperature sensor 290 detects the temperature in the water cavity, and then transmits the temperature information to the external PLC. Then, the external PLC controls the motor one 220 to start according to the required temperature. Then, the threaded rod 230 causes the L-shaped plate 240 to slide, enabling the water heater 250 to reach the top of a water cavity. Then, the water heater 250 is controlled to flow out cold water or hot water. Here, the protrusion on the L-shaped plate 240 presses against a touch switch 280, and then the solenoid valve pipe 270 matched with the touch switch 280 is opened. Then, the water in the above-mentioned water cavity flows out. When the temperature in the above-mentioned water cavity is lower than the required temperature, the water heater 250 is controlled to flow out hot water, and vice versa, cold water is flowed out. Then, the above steps are repeated to adjust the water temperature in another water cavity. The water temperatures in the two water cavities are different, achieving the condition of differential temperature. After that, when performing differential temperature treatment on the workpiece, the movable end of the cylinder 310 is controlled to extend, and then the top cover 120 drives the bracket 130 to leave the inside of the processing chamber 110. Then, the motor 320 is started, causing the top cover 120 to drive the bracket 130 to rotate, and then the two brackets 130 exchange positions. Then, the bracket 130 is controlled to return to the inside of the processing chamber 110, realizing differential temperature treatment. The adjustment method is simple and highly efficient.
