[0026] The technical solutions in the embodiments of the present application will be described below with reference to the drawings.

[0027] The embodiments of the present application are used for explaining the present application, and are not used for limiting the scope of the present application. In the following paragraphs, the present application is described in more detail with reference to the drawings. It should be noted that the drawings are very simplified and use non-precise proportions, and are only used for the purpose of conveniently and clearly assisting the description of the embodiments of the present application.

[0028] In the operation of the high-frequency curing device, the space surrounded by the induction coil needs to be detected. The temperature detection related device is usually installed in the space surrounded by the induction coil, however, the space is continuously in a high temperature state, which affects the service life of the device, thereby causing high loss of the device.

When the temperature sensor 1 is in the second position, the temperature sensor 1 is located outside the heating space, and since the temperature outside the heating space is low, the temperature sensor 1 can be cooled. It should be noted that the temperature outside the heating space is usually room temperature.

[0032] The driving member 2 can be used to drive the temperature sensor 1 to move or rotate. The driving member 2 is preferably used to drive the temperature sensor 1 to move, so that the driving member 2 can move the temperature sensor 1 from the first position to the second position or from the second position to the first position. When the driving member 2 is used to drive the temperature sensor 1 to move, the driving member 2 can be a pneumatic cylinder, a hydraulic cylinder, an electric push rod, etc.
