[0018] Figure 1 、 2, 3, 4, the thermistor H is negative temperature coefficient thermistor, the temperature sensing surface of the thermistor H is close to the inner side of the groove. The temperature control circuit includes resistors R1 and R2, a transistor T1, a relay J1, a power switch S1, and is connected to the thermistor H through a wire, one end of the thermistor H is connected to one end of the first resistor R1 and one end of the second resistor R2, the other end of the second resistor R2 is connected to the base of the transistor T1, the collector of the transistor T1 is connected to the negative input terminal of the relay J1, the positive power input terminal of the relay J1 and the control power input terminal are connected to one end of the power switch S1, the other end of the first resistor R1 is connected to the emitter of the transistor T1, and the other end of the power switch S1 is connected to the other end of the thermistor H. The trigger circuit is a relay J2, after the probe body 1 is placed at the lower end of the fixed position of the color Doppler ultrasonic diagnostic instrument, the upper end of the probe body 1 and the detection head of the infrared detection module E2 are in the same vertical plane. The lower end of the cover body is glued with an elastic sealing sheet 6 (sealing ultraviolet germicidal lamp light), and the middle part of the elastic sealing sheet 6 has an opening (the opening contact part is a sealing structure).

[0019] Figure 1 、 2 , 3, 4, after the 220V AC power supply enters the power input terminal of the power module E1, the 3, 4 pins of the power module E1 output stable DC 12V power to the power input terminals of the temperature control circuit 2 and the trigger circuit 3 (on the basis of opening the power switch). When the indoor temperature is relatively low in winter, the doctor can open the power switch S1, when the indoor temperature is higher than a certain temperature (such as higher than 35℃), the resistance value of the thermistor H is relatively small, and the voltage division between the thermistor H and the resistor R1 is relatively small. In this way, the 12V power supply is divided between the thermistor H and the resistor R1, and the resistor R2 limits the current to enter the base of the transistor T1, which is higher than 0.7V. The transistor T1 will be turned on, and the low level output from the collector will enter the negative power input terminal of the relay J1. The relay J1 will be energized to open the control power input terminal and the normally closed contact terminal, so that the electric heating plate RT will not be powered and heated. When the indoor temperature is lower than a certain temperature (such as lower than 35℃), the resistance value of the thermistor H is relatively low, and the voltage division between the thermistor H and the resistor R1 is relatively large. In this way, the 12V power supply is divided between the thermistor H and the resistor R1, and the resistor R2 limits the current to enter the base of the transistor T1, which is lower than 0.7V. The transistor T1 will be cut off, and the collector will no longer output low level to enter the negative power input terminal of the relay J1. The relay J1 will lose power and no longer attract the control power input terminal and the normally closed contact terminal to close, so that the electric heating plate RT will be powered and heated to heat the probe body 1. Through the above, the new type can maintain the temperature of the detection shell in real time during detection, and reduce the discomfort of patients caused by low temperature.
