[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 A three-way dual-channel compensation structure temperature controller includes a positioning column 1, a heating load component 2 and a thermal control switch structure 3 disposed on the positioning column 1.

[0024] A support plate 4 is riveted to the positioning column 1. An adjustment shaft 5 is provided on the support plate 4. An adjustment screw that is threadedly connected to the support plate 4 is provided at the lower end of the adjustment shaft 5. A ceramic column 6 is provided between the lower end of the adjustment screw and the thermal control switch structure 3.

[0025] The heating load assembly 2 includes two resistance compensation structures 21 and a mica compensation structure 22. Both the resistance compensation structure 21 and the mica compensation structure 22 are provided with terminals 23 and are connected to an external controller through the terminals 23.

[0026] In this utility model, the dual-path system composed of two resistor compensation structures 21 allows for different temperature variations, enabling flexible configuration and adjustment of the heating compensation temperature. This adapts to various testing requirements and standards under different conditions, and allows for arbitrary selection and conversion as needed. The single-path and dual-path systems can be arbitrarily selected and converted as required. By combining the gear switch and different wiring methods, different paths can be selected for the main terminal and the output terminal, resulting in different control effects.

[0027] At the same time, one temperature controller can achieve the effect of multiple temperature controllers; it is beneficial to the design and installation of the overall product structure, saves installation space, and reduces the complexity of product circuits by simplifying wiring, thus playing the role of controlling multiple devices with one device. By setting the mica compensation structure 22 and the resistance compensation structure 21 in combination, the variety of combinations can be further improved, thereby meeting the test requirements of more conditions, improving the applicability of the temperature controller, and meeting the needs of machines with various power ratings.

[0028] Furthermore, in this embodiment, the thermal control switch structure 3 includes a moving contact 31 and a stationary contact 32. The positioning post 1 is provided with a fixed contact piece 33 for mounting the stationary contact 32. When the moving contact 31 contacts the stationary contact 32, a current path is formed. When the moving contact 31 separates from the stationary contact 32, a current circuit is formed.

[0029] Furthermore, in this embodiment, the positioning post 1 is provided with a bimetallic strip 34, and the bimetallic strip 34 is connected to the mounting frame 36 through the ceramic chip 35. The moving contact is set on the mounting frame 36. When the temperature changes, the bimetallic strip 34 deforms, causing the ceramic chip 35 and the mounting frame 36 to move. When the moving contact 31 is separated from the stationary contact 32, a current circuit is broken, or when the moving contact 31 is in contact with the stationary contact 32, a current path is formed.

[0030] It should be noted that in this embodiment, a long spring piece 37 is provided on the positioning post 1, and a short spring piece 38 is movably inserted into the long spring piece 37. The short spring piece 38 is fixedly connected to the mounting frame 36. The ceramic post 6 contacts the upper end of the long spring piece 37. Rotating the adjusting shaft 5 drives the adjusting screw to rotate, and the adjusting screw drives the ceramic post 6 to descend, changing the height of the long spring piece 37 and the short spring piece 38, thereby adjusting the position of the mounting frame 36 and the moving contact 31. The lower the moving contact 31, the smaller the displacement required for the contact to disconnect, and the lower the deformation amplitude required for the bimetallic strip 34. Therefore, the temperature is lower when controlling the temperature.

[0031] Furthermore, in this embodiment, the resistance compensation structure 21 includes a resistance wire 211, each of which is provided with a terminal 23. A pad group 24 is provided between the two resistance compensation structures 21 to separate the two resistance wires 211 and prevent short circuits. The two resistance wires 211 can be varied at different temperatures to achieve flexible combination and small-amplitude adjustment of the heating compensation temperature.

[0032] More specifically, in this embodiment, the mica compensation structure 22 includes a mica sheet 221 sleeved on the positioning post 1, and a resistance wire 211 of a resistance compensation structure 21 in contact with the mica sheet 221. By setting the mica sheet 221 to cooperate with the resistance compensation structure 21, the variety of combinations can be further improved, thereby meeting the test requirements of more conditions, improving the applicability of the temperature controller, and meeting the needs of machines with various power ratings.

[0033] Working mode; During operation, the dual-path system composed of two resistance compensation structures 21 allows for different temperature variations, enabling flexible combinations and adjustments. It can slightly adjust the heating compensation temperature to adapt to various testing requirements and standards. The system allows for arbitrary selection and transformation as needed, with single-path and dual-path options available. Furthermore, by combining the mica compensation structure 22 with the resistance compensation structure 21, the variety of combinations is further enhanced.

[0034] When adjusting the trigger temperature of the thermostat, rotating the adjustment shaft 5 drives the adjustment screw to rotate, and the adjustment screw drives the ceramic column 6 to descend, changing the height of the long spring 37 and the short spring 38, thereby adjusting the position of the mounting frame 36 and the moving contact 31. The lower the moving contact 31 is, the smaller the displacement required for the contact to disconnect, and the lower the deformation amplitude required for the bimetallic strip 34 is. Therefore, the temperature is lower when controlling the temperature.

[0035] 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.
