To enable the device to fit against the upper part of the lips, the middle of the upper edge of the collection body 1 forms an arc portion 16 corresponding to the front part of the nasal tip and extends inwardly.

[0036] Thermocouples, the thermocouples are installed on the second body 10 and are electrically connected to the circuit board; three thermocouples are provided, namely a first thermocouple 11, a second thermocouple 12, and a third thermocouple 13; the first thermocouple 11 and the second thermocouple 12 are arranged in parallel on the upper edge of the second body 10; the third thermocouple 13 is arranged in the middle of the lower edge of the second body 10. Among them, the first thermocouple 11 and the second thermocouple 12 are used to measure the airflow data of the two nostrils, and the third thermocouple 13 is used to measure the airflow data of the mouth. The basic principle of the thermocouple is that a closed loop is composed of two conductors of different compositions of materials, and when there is a temperature difference at the two joints, an electric current will flow through the loop, and at this time, there is a thermal electromotive force (Seebeck effect) between the two ends. The analog-to-digital converter can convert the analog signal (voltage) into a digital signal, that is, convert the electromotive force generated by the thermocouple due to the oral and nasal airflow into a digital signal, which can then be displayed and processed and analyzed by the upper computer. The data collected by the thermocouple is mainly the oral and nasal airflow, that is, the breathing airflow conditions of the mouth and nose parts, and corresponding signals are generated according to the size and heat of the airflow.

[0037] A sound pickup hole 15 with a built-in microphone, the sound pickup hole 15 is located in the middle of the second body 10; the microphone is used to collect the nasal airflow data and snoring data of the subject.

[0042] In this solution, the nose and mouth airflow acquisition unit 1 is installed above the lips, and the main patch unit 2 is installed above the forehead.
