The temperature sensor is a key component for stainless steel thermos cup to achieve precise temperature control. It can monitor the temperature of the liquid in the cup in real time and convert the temperature data into an electrical signal to transmit to the control system. Common types of temperature sensors include thermistor sensors. In the use scenarios of thermos cups, such as making tea, different types of tea require appropriate water temperature to brew to ensure the maximum precipitation of taste and nutrients.
The temperature sensor can accurately sense the water temperature. When the water temperature is too high and may damage the nutrition or taste of the tea, it starts the temperature control program, allowing users to enjoy the drink at the right temperature, improving the functionality and user experience of the thermos cup.
2. Data acquisition and transmission of precise temperature control principle
The temperature sensor contacts the liquid in the cup through its sensitive element, and uses the characteristic that the resistance value of the thermistor changes with temperature to collect temperature data. When the temperature of the liquid changes, the resistance value of the thermistor changes accordingly, causing the current or voltage in the circuit to change, and this change represents the temperature information. These electrical signals are transmitted to the microprocessor or control chip of the thermos cup through built-in wires or wireless transmission modules.
For example, in some smart stainless steel thermos cups, the temperature sensor collects temperature data at regular intervals and transmits it quickly to ensure that the control system can grasp the temperature dynamics in the cup in time.
3. Control and regulation of precise temperature control principle
After receiving the signal from the temperature sensor, the microprocessor will analyze and judge according to the preset temperature program.
If the temperature in the cup is higher than the set target temperature, the control system will start the cooling mechanism, such as controlling the heat dissipation device of the thermos cup (if any) to increase the heat dissipation power, or adjusting the liquid circulation in the cup (in some complex thermos cup designs) to speed up the heat dissipation; conversely, if the temperature is lower than the target temperature, the heating element (if equipped) may be started for appropriate heating. Taking the thermos coffee set at 50℃ as an example, when the temperature sensor detects that the temperature rises to 52℃, the control system will let the thermos cup enter the heat dissipation regulation, so that the temperature gradually drops back to 50℃ and maintains stability, thereby achieving precise temperature control.
4. Technical Challenges and Development Trends
Although the temperature sensor and precise temperature control technology of the stainless steel thermos cup have achieved certain results, there are still some challenges.
For example, the long-term stability and accuracy of the temperature sensor may be affected by long-term use and different environments, and the sensor material and calibration technology need to be continuously optimized. In addition, it is also difficult to reasonably arrange the temperature sensor and other temperature control components in the limited space of the miniaturized thermos cup. In the future, with the development of materials science and electronic technology, it is expected that more sensitive, more accurate and miniaturized temperature sensors will be developed. At the same time, the temperature control algorithm will be more intelligent and efficient, and it can perform dynamic and precise temperature control according to different beverages and user personalized needs, further improving the quality and practicality of the stainless steel thermos cup.
