AI Technical Summary
Technical Problem
Conventional contact thermostats have slow thermal response rates and are not reusable, leading to sluggish temperature control and high costs due to non-reusable fuse-cutting protection structures.
Method used
An overheat recovery stopper protector with a base, electrical terminals, a spring piece, and a temperature-sensing piece, featuring a return stopper structure that includes a limit hook and a return-stopping elastic piece, allowing for rapid temperature sensing and one-time overheat protection with reusability.
Benefits of technology
The protector provides rapid temperature sensitivity and one-time overheat protection, enhancing thermal response and reducing costs by allowing reuse without replacing components.

Abstract
It provides a one-time overheat protection function. [Solution] The base is provided with a first electrical terminal, a second electrical terminal, a spring piece, and a temperature-sensing piece. The first end of the spring piece is fixedly connected to the first electrical terminal, and the second end of the spring piece is installed corresponding to the second electrical terminal. The temperature-sensing piece is installed above the spring piece, and the first end of the temperature-sensing piece is fitted and connected to the first electrical terminal, and the second end of the temperature-sensing piece is fitted and connected to the second end of the spring piece. The base is provided with a return stopper structure, which is fitted and connected to the second end of the spring piece. By installing the temperature-sensing piece in an exposed state, sensitivity to ambient temperature can be increased. When the temperature reaches a critical value, the temperature-sensing piece moves to turn off the connection of the spring piece, thereby turning off the circuit. Due to the deformation of the temperature-sensing piece, the spring piece can move over the return stopper structure and fit and connect to it, preventing the temperature-sensing piece from deforming again and returning the spring piece to its original state, thereby realizing a one-time overheat protection function.
