With the arrival of summer, the weather gradually becomes hot and humid, making it the perfect time to brew a pot of fragrant flower tea. Health-preserving kettles play a vital role during this season, as their gentle bubbling sound and the ability to brew chilled or warm flower tea offer both refreshment and wellness, bringing a sense of summer coolness and comfort.
As people place more importance on healthy living, more young people are beginning to pay attention to daily health maintenance. Health-preserving kettles, as convenient and efficient wellness tools, are gradually becoming a part of everyday life in many households. With so many options available in the market, it is especially important to choose a kettle with complete basic functions, a reputable brand, and excellent quality to avoid potential safety risks during use.
Behind these functions, electronic components—specifically thermistors—play a crucial role. Thermistors offer many advantages, including high sensitivity, fast response time, small size, low cost, good stability, and ease of use. As a result, they are widely used in temperature measurement, control, and monitoring, making them indispensable components in many electronic devices.
In health-preserving kettles, thermistors are placed near the heating element to monitor the water temperature in real-time. Thermistors are components whose resistance changes in response to temperature variations. They are categorized into two types based on their temperature coefficient: NTC (Negative Temperature Coefficient) and PTC (Positive Temperature Coefficient). The resistance of an NTC thermistor decreases as temperature rises, while the opposite occurs with PTC thermistors.
As the water temperature changes, the resistance of the thermistor also changes, and these variations are converted into electrical signals sent to the control system. Upon receiving the signal, the system adjusts the heating element's power to accurately control the water temperature, ensuring precise heating every time.
Thanks to the assistance of thermistors, health-preserving kettles can brew fragrant flower teas, whether it's chrysanthemum, rose, or jasmine, releasing the most pleasant fragrance and making summer wellness both easy and enjoyable.
