[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The gas detector with adjustable sampling aperture is provided with an air acceleration component group and an aperture adjustment component group. The existing gas detector can detect gas by directly contacting the detection probe with the air, but lacks a structure to accelerate the air flow. The probe can only passively detect the air flowing through it, and cannot accelerate the flow speed of the air around the probe to improve the detection efficiency, thereby affecting the use efficiency. In the correspondingly designed air acceleration component group and aperture adjustment component group, when it is necessary to accelerate the speed of the air flow on the detection probe, the hand holding the handle can turn on the servo motor by controlling the control switch. After the servo motor is turned on, the fan blades are driven to rotate through the working end. Figure 3 Opening the central direction fan blade will make the air flow quickly from left to right. The rapid flow of air can speed up the amount of air passing through the detection probe, thereby speeding up the detection probe's inspection speed of the air and improving the use efficiency of the gas detector.

[0014] 2. This gas detector with adjustable sampling aperture is provided with an air acceleration component group and an aperture adjustment component group. In the correspondingly designed air acceleration component group and aperture adjustment component group, the air inlet aperture of the sampling air inlet of the outer cylinder can be controlled by rotating the angle of the adjustment plate. When the angle of the adjustment plate needs to be adjusted, the handle is pulled downward. When pulled, the spring part accumulates force and stretches, and the pin part is pulled out from the through hole of the upper stabilizing frame and the cross bar. After being pulled out, the handle can be pulled to adjust the angle position of the adjustment plate. After adjustment, the handle is released, and the spring part accumulates force and contracts to pull the handle, so that the pin part is reinserted into the upper stabilizing frame and the cross bar to complete the locking of the adjustment plate position. The design of this aperture adjustment component group can adjust the aperture of the sampling air inlet. The adjustment provides flexibility and adjustability, so that the gas detection system can adapt to different environments and gas concentration requirements, and realizes precise adjustment of the air inlet aperture. This precise control helps to ensure the accuracy and reliability of gas sampling. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Working principle: Current gas detectors can detect gas by directly contacting the detection probe with the air, but lack a structure to accelerate the air flow. The probe can only passively detect the air flowing through it, and cannot accelerate the flow speed of the air around the probe to improve the detection efficiency, which in turn affects the use efficiency.

The spring member 32 accumulates force and contracts to pull the handle 31, so that the pin member 33 is reinserted into the upper stabilizing frame 37 and the cross bar member 34 to complete the locking of the position of the adjustment plate 36. The design of this caliber adjustment component group 03 can adjust the caliber of the sampling air intake.
