The thermocouple sensor 125 is installed at the bottom of the housing 121, and the thermocouple sensor 125 is electrically connected to the temperature controller 123, so that the thermocouple sensor 125 can contact the bottom of the diagnostic head assembly 11 to detect the temperature of the portion of the diagnostic head assembly 11 contacting the human body, thereby feeding back the temperature to the temperature controller 123 in real time, and the temperature controller 123 controls the frequency converter 124 according to the real-time temperature value to adjust the heating power of the heating coil (not shown), thereby performing temperature regulation in real time. In this way, the constant temperature shell 111 can be heated through the heating coil (not shown), the temperature of the constant temperature shell 111 is transferred to the acoustic aluminum film 112, so that the acoustic aluminum film 112 is heated, and in a working environment with lower temperature, the temperature of the acoustic aluminum film 112, which is in contact with a human body, of the stethoscope can be kept within a preset temperature value in such a way, the control is accurate, and the auscultation and diagnosis accuracy is ensured.

Specifically, the temperature controller 123 is connected to a thermocouple temperature sensor, from which real-time temperature data of the acoustic aluminum film 112 is obtained. The 37 c may be set to a set temperature for automatic temperature control by the mode setting button 135. After the start button 134 is turned on, the temperature controller 123 is started when the temperature of the aluminum listening film 112 is lower than 37 ℃, and stops when the temperature of the aluminum listening film 112 is higher than 37 ℃ set by a user, the temperature value of the aluminum listening film 112 allows an error of +/-1 ℃, and the temperature controller 123 judges that heating or temperature control should be adopted according to temperature data.
The frequency converter 124 adopts PWM control, also called voltage and frequency proportional modulation. The frequency is regulated, the amplitude of the pulse voltage is not changed, but the duty ratio of the pulse is changed, and the effects of frequency conversion and voltage transformation can be realized. The PWM modulation method can directly finish the simultaneous change of voltage and frequency in the inverter, and the control circuit is simpler. The temperature controller 123 is connected with the frequency converter 124, and the instructions are transmitted to the frequency converter 124 through analog signals to make the frequency converter respond.

For example, when the temperature of the listening aluminum film 112 is lower than 36 ℃ by setting the temperature to 36 ℃, the temperature controller 123 takes heating measures, the frequency converter 124 takes high frequency, and the heating power of the heating coil (not shown) is large and reaches 36 ℃ rapidly. After the temperature of the listening aluminum film 112 reaches 36 ℃, a control range of + -1 ℃ is set in the temperature controller 123, the temperature controller 123 adopts a temperature control measure, the frequency converter 124 adopts a low frequency to control the temperature, the temperature controller 123 sends a signal to the frequency converter 124 after the temperature exceeds (is lower than or higher than) the range of + -1 ℃, and the frequency converter 124 controls the heating power of a heating coil (not shown) or stops heating, so that the temperature of the listening aluminum film 112 of the stethoscope is always kept within the set temperature value range.
Therefore, the stethoscope 10 with the temperature control function can heat and control the temperature of the stethoscope head assembly 11 based on the frequency conversion technology, so as to avoid the stimulation to the heartbeat and the respiration of a person caused by the too low temperature of the stethoscope head assembly 11, and ensure the accuracy of auscultation results and diagnosis results. The medical staff automatically adjusts the heating power and time of the heating coil (not shown) and controls the temperature to make the temperature of the portion of the diagnostic head assembly 11 contacting the human body reach a designated temperature using the temperature controller 123 and the frequency converter 124.
