A limiting tube 505 is inserted into one side of the sliding plate 504. One side of the limiting tube 505 is threadedly connected to one side of the sliding plate 501. A motor 506 is fixedly installed on one side of the inner wall of the cavity. A lead screw 507 is fixedly installed on the output shaft of the motor 506. One end of the lead screw 507 passes through the sliding plate 502 and extends to the outside of the sliding plate 502. An electronic control component is also included. The output terminal of the thermometer 4 is electrically connected to the electronic control component. The output terminal of the electronic control component is electrically connected to the motor 506 and the sliding resistor 500, respectively. The adjustable component 5 allows adjustment of the resistance value of the sliding resistor 500 during use by adjusting the position of the sliding plate 501 on the sliding resistor 500. This adjustment controls the current and thus the heating state of the heating tube 3, thereby achieving temperature control of the device and improving its ease of use.

[0022] Both sides of the positioning plate 2 are fitted with screws 508. One end of the screw 508 passes through the positioning plate 2 and extends to the outside of the positioning plate 2. The positioning plate 2 has a screw hole for the screw 508 to pass through. The screw hole is threadedly connected to the screw 508. The positioning plate 2 and screws 508 facilitate the insertion of the device on one side of the phase change energy storage device and then position it for installation. This facilitates the installation and disassembly of the device, and makes it easier for the temperature control device to be disassembled, installed, maintained, and repaired. It also makes it easier for the staff to operate.

[0023] A rod 509 is inserted into the top of the sliding plate 504. A baffle 510 is fixedly installed on the top of the rod 509. A return spring 511 is arranged around the surface of the rod 509. The top of the return spring 511 is fixedly connected to the bottom of the baffle 510, and the bottom of the return spring 511 is fixedly connected to the top of the sliding plate 504. The return spring 511 and the bottom of the rod 509 are inserted into the surface of the limiting tube 505. During use, it is convenient to reset the rod 509 on the baffle 510, thereby facilitating the limiting insertion operation of the limiting tube 505.

[0024] Reference Figure 2 In a preferred embodiment, support plates 6 are fixedly installed on both sides of the bottom of the base 1. A positioning hole is provided on one side of the support plate 6. The positioning hole is an oblong hole. Anti-slip texture is provided on one side of the support plate 6. The support plate 6 can be positioned and installed during use, thereby maintaining the installation stability of the component and facilitating the operation of the staff.

[0025] Reference Figure 3 In a preferred embodiment, the conductive electrodes of the sliding resistor 500 are respectively connected to the positive and negative electrodes of the heating tube 3. The slide plate 502 has a threaded hole for the lead screw 507 to pass through, and the threaded hole is threadedly connected to the lead screw 507. One end of the lead screw 507 is fitted with a sleeve that is rotatably connected to the lead screw 507. One end of the sleeve is fixedly connected to one side of the inner wall of the cavity. The lead screw 507 is threadedly connected to the threaded hole of the slide plate 502. During use, the position of the slide rod 503 on the slide plate 502 can be moved as the lead screw 507 rotates, which also facilitates subsequent operations.

[0026] Working principle: During use, the temperature control device is inserted into the mounting hole on one side of the phase change energy storage device, so that the heating tube 3 and the thermometer 4 are located inside the phase change energy storage device. Then, the screw 508 is tightened so that one side of the positioning plate 2 is tightened with one side of the phase change energy storage device. Then, the support plate 6 is positioned and connected to the device through the connector. Then, the thermometer 4 monitors the temperature inside the phase change energy storage device. When the temperature inside the phase change energy storage device decreases, the control motor 506 is activated, so that the motor 506 drives the slide plate 502 on the lead screw 507 to move. This causes the slide rod 503 to drive the limit tube 505 and the slide plate 501 on the moving plate 504 to move, so that the resistance of the sliding resistor 500 decreases, thereby increasing the current through the heating tube 3. Then, the heating tube 3 heats the inside of the device, raising its temperature. Conversely, the control device lowers the heating temperature.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
