Temperatures for winter: Thermistors in electric blankets

As the weather gets colder, people start wearing cotton and down jackets to keep warm, and also use hot water bottles, heating pads, electric blankets, etc. to survive the winter. Electric blankets are very popular in my country and are also loved by foreign friends. Before soaking your feet at night, turn on the electric blanket to warm the bed, and after soaking your feet, turn off the electric blanket and lie on the warm bed. How comfortable it is. Sleeping in a warm bed in winter makes even dreams warm.

Why are electric blankets more popular than hot water bottles and heat packs? Because electric blankets are easy to use, heat quickly, can adjust the temperature, have a large area, and can warm the entire bed. Electric blankets can control and adjust the temperature thanks to electronic components - thermistors.

The ability of thermistors to control and adjust temperature is related to their characteristics. Thermistors are highly sensitive and can sense temperature changes, and their resistance will change with temperature changes.

When the thermistor in the electric blanket is working, the temperature of the thermistor is the same as the ambient temperature, the resistance is very small, and it will not hinder the flow of current when connected in series in the circuit. When the circuit has overcurrent due to a fault, the temperature of the thermistor rises due to the increase in heat power. When the temperature exceeds the switch temperature, the resistance will increase sharply in an instant, suppressing the overcurrent in the circuit. The current decreases rapidly to prevent excessive current from causing overheating and burning the electric blanket, causing an accident.

Thermistors have many advantages and a wide range of uses. As temperature control elements, thermistors can be used not only in electric blankets, but also in induction cookers, rice cookers, microwave ovens and other household appliances. The characteristics of thermistors are used to control and adjust the temperature.

It should be noted that there are many types of thermistors, and not all thermistors can be used in electric blankets. When selecting a thermistor, it is necessary to consider the working environment of the thermistor, the rated voltage and capacitance of the thermistor to select a suitable thermistor.

If you need an electronic component that can control temperature, a thermistor is a good choice. There are many types of thermistors. If you don't know how to choose, find a thermistor manufacturer with a good brand, good reputation, and reliability, tell the staff your needs, and the staff will provide you with a suitable solution based on your needs.
