Many small household popcorn makers have overheat protection and automatic stop functions, which can improve safety and avoid equipment damage. When the maker is in use, if the internal temperature is too high, the built-in temperature control system will detect this and automatically cut off the power or stop heating, preventing the maker from malfunctioning or causing safety issues such as fires due to overheating. In addition, most makers will automatically stop heating the popcorn after it is made, so as not to overheat and cause the popcorn to burn. The automatic stop function is usually controlled by a timer, thermostat, or thermal protection device inside the maker, ensuring easy operation and greater safety. Overall, these functions can effectively extend the service life of the maker and improve safety during operation. However, it should be noted that the specific functions and working principles may vary depending on the brand and model. When choosing, you can refer to the manual or product introduction for confirmation.
