In medical paraffin bath beauty instruments, the temperature control system plays a decisive role. If the temperature is too high, medical wax can easily burn the skin and destroy the effective ingredients of the wax material; if the temperature is too low, the wax bath cannot fully exert its warming effect, promote blood circulation and soften keratin. Accurate temperature control can ensure that medical wax melts and solidifies in the appropriate temperature range, so that the beauty instrument can achieve the ideal physiotherapy and beauty effects, while ensuring the safety of users. Therefore, it is very important to optimize the temperature control system.
As the "eyes" of the temperature control system, the accuracy of the temperature sensor directly affects the temperature control effect. Although the traditional thermistor sensor has low cost, it has problems such as large temperature drift and slow response speed. In order to improve the accuracy of temperature control, a high-precision platinum resistance temperature sensor can be selected. Platinum resistance has the characteristics of good linearity, high stability and wide temperature measurement range. It can control the measurement error within a very small range within the commonly used wax bath temperature range of 0℃ - 150℃. At the same time, through the layout of multi-point temperature sensors, sensors are installed at different positions of the wax bath to monitor the temperature distribution in real time to avoid local overheating or overcooling.
Advanced temperature control algorithms are the core of achieving precise temperature control. Although traditional PID control algorithms are widely used, it is difficult to achieve ideal results when faced with the characteristics of temperature lag and nonlinearity of paraffin bath beauty instrument. The introduction of adaptive fuzzy PID algorithm can automatically adjust the proportional, integral and differential parameters according to the dynamic characteristics of temperature change. For example, in the initial heating stage of medical wax, increase the proportional coefficient to speed up the heating speed; when approaching the target temperature, reduce the proportional coefficient to reduce the overshoot. In addition, combined with the neural network algorithm, by learning a large amount of historical temperature data, predict the temperature change trend, adjust the heating power in advance, and further improve the accuracy and stability of temperature control.
The performance of the heating element and the insulation structure design affect the efficiency and accuracy of temperature control. The new nano-coated heating film is used to replace the traditional heating wire. The nano-coated heating film has the advantages of uniform heating and high heat conversion efficiency, which can reduce the temperature gradient in the wax bath. At the same time, the insulation structure is optimized, and multiple layers of composite insulation materials are wrapped around the outside of the wax bath. The inner layer uses aerogel felt with low thermal conductivity, and the outer layer uses high-strength polyurethane foam, which effectively reduces heat loss, maintains temperature stability, and reduces the adjustment frequency of the temperature control system, thereby improving the temperature control accuracy.
During long-term use, the temperature sensor may drift, affecting the accuracy of temperature control. Establish a regular temperature calibration mechanism, use a high-precision standard thermometer to calibrate the temperature display of the paraffin bath beauty instrument, and correct the measurement error. In addition, considering the impact of ambient temperature on the temperature control system, design an ambient temperature compensation algorithm. When the ambient temperature is low, the heating power is automatically increased to compensate for heat loss; when the ambient temperature is high, the heating power is appropriately reduced to ensure accurate temperature control in different environments.
The perfect real-time monitoring and feedback adjustment system can capture temperature changes in time and respond. The display screen is integrated in the temperature control system to display information such as wax bath temperature, set temperature, heating status, etc. in real time, so that operators can intuitively understand the operation of the equipment. At the same time, the data collected by the temperature sensor is transmitted to the control chip in real time. Once the temperature is detected to deviate from the set range, the control chip immediately adjusts the working state of the heating element, and realizes rapid temperature adjustment and stabilization through closed-loop feedback control.
The optimized temperature control system needs to be fully tested and verified. The stability and reliability of the temperature control system are tested by simulating different usage scenarios, such as continuous long-term work, frequent start and stop, etc. The temperature recorder is used to monitor the temperature at different positions in the wax bath for a long time, and the temperature fluctuation range and uniformity are analyzed. Invite professional medical staff and beauticians to experience the actual operation of the optimized paraffin bath beauty instrument, evaluate the impact of temperature control on beauty and physical therapy effects, and further optimize the temperature control system according to the test and feedback results to ensure its optimal performance.
