Problems solved by technology
[0003] However, the birdcage heaters and electric heating fans of the prior art do not have an over-temperature power-off protection switch. Even if the heating power is adjusted, the temperature will still increase continuously as time goes on, and the temperature will not be extended at any time. And stop, it will not stop with the increase of temperature, because of this situation, many fire accidents are caused, and the safety is poor; currently on the market, such as button-type temperature insurance such as KDS301, etc., are not suitable for this type of product and cannot be used. Realizing the function of timing power-off, it is impossible to generate an alarm indicator that can be directly perceived by the human body, and the reliability is poor; at the same time, the over-temperature and continuous power-off also causes energy waste

The invention discloses an electronic over-temperature circuit breaker which comprises a heating device used for converting electric energy of an external power supply into heat energy, a control device used for controlling power-on and power-off of the heating device, a temperature sensor used for detecting and acquiring temperature information of heat energy generated by the heating device, a microprocessor used for collecting the temperature information, converting the temperature information into temperature digital information and controlling the action of the control device according tothe temperature digital information and the heating time information of the heating device and a preset program rule, and a resistance-capacitance voltage reduction circuit connecting the microprocessor with the external power supply and used for reducing the voltage of alternating current of the external power supply and converting the alternating current into direct current so as to supply powerto the microprocessor and the control device. Compared with the prior art, the electronic over-temperature circuit breaker is good in safety and reliability and capable of saving energy.
Description
【Technical field】 [0001] The invention belongs to the technical field of electronic devices, and in particular relates to an electronic over-temperature breaker. 【Background technique】 [0002] Existing birdcage heaters and electric heating fans have simple power adjustment, and can adjust the speed of heating to meet the basic requirements of people's heating in winter. [0003] However, the birdcage heaters and electric heating fans of the prior art do not have an over-temperature power-off protection switch. Even if the heating power is adjusted, the temperature will still increase continuously as time goes on, and the temperature will not be extended at any time. And stop, it will not stop with the increase of temperature, because of this situation, many fire accidents are caused, and the safety is poor; currently on the market, such as button-type temperature insurance such as KDS301, etc., are not suitable for this type of product and cannot be used. Realizing the fun...
