[0041] In this embodiment, after the detection is completed, hold the handle 9 and rotate it. After the handle 9 rotates, the movable sleeve 2 is controlled to rotate until the air path 4 22 is connected with the air path 2 20, and then the micro pump 24 is controlled to start. After the micro pump 24 is started, the external air is sucked in and the internal passage is cleaned. This can facilitate reuse and avoid residual gas affecting secondary detection.

[0042] like Figure 6 As shown, a reminder mechanism is provided inside the bottom end of the conduit 1, and the reminder mechanism includes an air pressure sensor 27.

[0043] In this embodiment, after the gas enters the person being tested from gas circuit one 14, it enters gas circuit two 20, then enters from gas circuit three 21 on one side of the movable sleeve 2, and then enters gas circuit five 25.

Finally, the gas is discharged from the one-way valve 28 below, so that during the test, it can be confirmed in real time whether the person being tested has blown in a sufficient amount of gas, thereby preventing the person being tested from deliberately avoiding the test, which affects the accuracy of the test.

[0044] A detection method of an exhaled gas detection device comprises the following steps:

[0045] Step 1: Before use, twist the rotating head 15. When the rotating head 15 rotates, it drives the air inlet nozzle 16 to adjust its position horizontally until the air inlet nozzle 16 overlaps with the air path 14 on one side of the air delivery pipe 6, so that the passage can be opened. After use, reverse the rotating head 15, and the air path 14 can be sealed by the rotating head 15.

[0046] Step 2, after the passage is opened, the person being tested blows gas from the air inlet nozzle 16, the gas is input into the interior along the gas path 14, and is ejected from the side slot 1 7 and the side slot 2 10 at the same time. If the gas ejected from the side slot 1 7 contains the component to be detected, it can be detected by the gas chromatograph 8 and then displayed on the touch screen 5, and the gas ejected from the side slot 2 10 is detected by the gas sensor 11. At this time, the gas sensor 11 controls the lamp body 13 inside the lampshade 12 to light up, indicating that the person being tested has indeed blown in the gas to cooperate with the detection;

[0047] Step 3, after the gas enters the detected person from the gas path 1 14, it enters the gas path 2 20, then enters from the gas path 3 21 on the side of the movable sleeve 2, and then enters the gas path 5 25. At this time, the air pressure sensor 27 inside the gas path 5 25 will detect that if the gas pressure reaches the threshold, the air pressure sensor 27 will control the lamp body 2 30 inside the lamp cover 29 to light up, indicating that the amount of gas sprayed by the detected person is sufficient, and finally the gas is discharged from the one-way valve 28 below;

[0048] Step 4, after the detection is completed, hold the handle 9 and rotate it. After the handle 9 rotates, the movable sleeve 2 is controlled to rotate until the air path 4 22 is connected with the air path 2 20, and then the micro pump 24 is controlled to start. After the micro pump 24 is started, the external air is sucked in and the internal passage is cleaned.

[0049] Working principle: Before use, twist the rotating head 15. When the rotating head 15 rotates, it drives the air inlet nozzle 16 to adjust its position horizontally until the air inlet nozzle 16 overlaps with the air path 14 on one side of the air supply pipe 6, so that the passage can be opened. After use, reverse the rotating head 15, and the air path 14 can be sealed through the rotating head 15. After the passage is opened, the person being tested blows gas into the air from the air inlet nozzle 16, and the gas is input into the inside along the air path 14, and is ejected from the side groove 17 and the side groove 2 10 at the same time. If the gas ejected from the side groove 7 contains the component to be detected, it can be detected by the gas chromatograph 8 and then displayed on the touch screen 5, and the gas ejected from the side groove 2 10 is detected by the gas sensor 11. At this time, the gas sensor 11 controls the lamp body inside the lampshade 12 13 lights up, indicating that the person being tested has indeed blown in gas to cooperate with the test. After the gas enters the person being tested from gas path 14, it enters gas path 2 20, and then enters from gas path 3 21 on the side of the movable sleeve 2, and then enters gas path 5 25. At this time, the air pressure sensor 27 inside gas path 5 25 will detect it. If the gas pressure reaches the threshold, the air pressure sensor 27 will control the lamp body 2 30 inside the lampshade 29 to light up, indicating that the amount of gas sprayed by the person being tested is sufficient. Finally, the gas is discharged from the one-way valve 28 below. After the test is completed, hold the handle 9 and rotate it. After the handle 9 rotates, the movable sleeve 2 is controlled to rotate until the gas path 4 22 is connected to the gas path 2 20, and then the micro pump 24 is controlled to start. After the micro pump 24 is started, it will suck in external air and clean the internal passage.
