The electric shoe shine machine is an electronic product that is transformed and invented according to the traditional manual shoe shine process combined with modern technology.
The electric shoe polisher consists of a control circuit and a mechanical transmission part. Among them, the mechanical transmission part is driven by a small motor to rotate a roller with a brush to achieve the purpose of sassafras shoes, and the core is a small motor. In this transmission system, the small motor is prone to overload or gamble due to problems such as lack of lubricating oil, bearing wear, rust, dust, and different strength of the foot. In severe cases, the motor and wires will be burned out, and even a fire accident may be caused. Therefore, it is necessary to design temperature protection and rotation protection circuits for the motor to ensure safe operation.
Regarding the protection of the motor, we can choose a bimetal temperature switch. After the motor is overloaded or locked, the current is very large, causing its temperature to rise rapidly. When the bimetal temperature switch senses high temperature, the circuit is disconnected, and the motor temperature drops, thus protecting the use of the motor and protecting against large currents. . However, many customers worry that after the temperature of the motor drops, the temperature switch will turn on the motor that has been rotated again, the motor will start in a cycle, and the temperature control switch will be protected again when it continues to heat up, and this cycle will operate. If the user cleans up foreign objects after the motor is turned, or the motor suddenly runs during inspection, it will cause personal injury and other accidents. Don't worry about this, we have also upgraded the product in response to this phenomenon.
We make the product into a power-off reset type temperature switch for the overload protection and temperature protection of the motor, so there will be no bad consequences or disasters caused by the repeated starting of the motor. The power-off reset type temperature switch can not only complete the overcurrent protection and Temperature protection, and will keep this protection state until the power is turned off to restore the initial state. This can effectively avoid various possible and potential problems and potential safety hazards of the above-mentioned automatic shoe shine machine.

Huizhou Huakai Electronic Technology Co., Ltd. specializes in R&D, production and sales of various thermal protectors, thermal fuses, NTC thermistor temperature sensors, and insulating temperature resistance bushings. We can match the most suitable temperature switch model according to the customer's motor performance.
