[0022] Specifically, the base plate 1 serves as the supporting foundation for the entire device, ensuring its stability. A handle 2 is fixedly connected to the center of the lower surface of the base plate 1, allowing users to hold or move the device. At the same time, a motor 11 is also fixedly connected to the lower surface of the base plate 1 and installed in the mounting slot inside the handle 2, saving space and protecting the motor 11 from external environmental interference. The rotating shaft 12 is connected to the motor 11, and the other end passes through the upper surface of the base plate 1 and connects to the base 3 located directly above the base plate 1. The lower surface of the base 3 has a rotating hole, and the end of the rotating shaft 12 away from the motor 11 is located in this rotating hole, realizing the rotation function of the base 3.

[0023] Reference Figure 1 , Figure 2 and Figure 3 A surrounding plate 4 is fixedly connected to the upper surface of the base 3. A support plate 5 is located on the right side of the surrounding plate 4 and they are interconnected. A support plate 5 is fixedly connected to the upper surface of the base 3. A bracket plate 7 is fixedly connected to the inner side wall of the support plate 5. A motor 8 is fixedly connected to the right surface of the bracket plate 7. A rotating shaft 9 is fixedly connected to the output end of the motor 8. An exhaust fan blade 10 is fixedly connected to the end of the rotating shaft 9 away from the motor 8. The rotating shaft 9 passes through the left surface of the bracket plate 7. The exhaust fan blade 10 is located on the left side of the bracket plate 7. A gas detector 6 is threadedly connected to the inner side wall of the support plate 5. The gas detector 6 covers the right surface of the support plate 5 and is located on the right side of the motor 8 and the exhaust fan blade 10.

[0024] Specifically, a surrounding plate 4 is fixedly connected to the upper surface of the base 3. The surrounding plate 4 and the support plate 5 are interconnected, forming a closed space. The support plate 5 is located on the right side of the surrounding plate 4, providing an installation position for the gas detector 6 and the exhaust system. The bracket plate 7 connected to the inner side wall of the support plate 5 provides support for the motor 8 and the rotating shaft 9. One end of the rotating shaft 9 is connected to the motor 8, and the other end passes through the left surface of the bracket plate 7 and is connected to the exhaust fan blade 10. The exhaust fan blade 10 is located on the left side of the bracket plate 7. When the motor 8 starts, the rotating shaft 9 drives the exhaust fan blade 10 to rotate, thereby generating airflow and introducing volatile organic gases into the gas detector 6. The gas detector 6 is fixed to the inner side wall of the support plate 5 by a threaded connection. It covers the right surface of the support plate 5 and is located on the right side of the motor 8 and the exhaust fan blade 10, so that the gas detector 6 can accurately detect the volatile organic gases introduced through the exhaust fan blade 10, thereby achieving effective detection of volatile organic gases in the environment.

[0025] Working principle: On the upper surface of the base 3, the enclosure plate 4 and the support plate 5 are interconnected, forming a closed space. A gas detector 6 and an exhaust system are installed within this space. When motor 8 starts, the rotating shaft 9 connected to its output end begins to rotate. The other end of the rotating shaft 9 is connected to the exhaust fan blade 10, so the exhaust fan blade 10 also rotates with the rotating shaft 9. The rotation of the exhaust fan blade 10 generates airflow, which draws the surrounding volatile organic gases into the closed space formed by the enclosure plate 4 and the support plate 5. When volatile organic gases are drawn into the closed space, the gas detector 6 can accurately detect these gases. When it is necessary to adjust the gas intake angle, motor 11 starts to work. The output end of motor 11 is connected to the rotating shaft 12, so the rotating shaft 12 rotates with the rotation of motor 11. The other end of the rotating shaft 12 passes through the upper surface of the base plate 1 and is connected to the rotating hole on the lower surface of the base 3. Thus, when the rotating shaft 12 rotates, the base 3 also rotates. The rotation function of the base 3 allows the device to adjust the detection direction to better adapt to different detection environments.
