Cooking machine and NTC temperature sensor.Automatic machine mirror

　　Cooking machines usually have mixing and heating functions. It mainly includes: a body with rotational driving function; Cup body installed on the machine body; And a stirring device installed in the cup body and driven by the body rotation. The cooking machine also has a heating device installed around the cup body, which is usually in direct contact with the cup body. The cup body is equipped with an NTC temperature sensor to monitor the temperature of the cup body and provide feedback to the food processing machine, thereby controlling the temperature of the food cooked inside the cup body.

　　NTC temperature sensor for cooking machine adopts high-precision NTC thermistor, welding wires, and double-layer sealing process, which has the advantages of high reliability, good stability, strong waterproof performance, etc.

　　The following is the preparation method for NTC temperature sensors used in cooking machines:

　　(1) The thermistor is welded and connected to the electronic wire, and then wrapped with sealing material to seal the thermistor and the welding point, and subjected to high-temperature sintering;

　　(2) Place the encapsulated thermistor inside the shell and expose the electronic wires. Inject or encapsulate the sealing material between the thermistor and the shell and conduct high-temperature sintering;

　　(3) Wrap the tail of the electronic wire exposed to the shell with packaging material, expose the wire core of the electronic wire, and conduct high-temperature sintering on the packaging material to obtain a temperature sensor.
