[0035] Working principle:

[0036] In the actual design process of the present utility model, in order to avoid the following defects existing in the prior art: "In the process of using the individual dust sampler of the prior art, an air pump is mainly used for air extraction and detection. However, during the process of air extraction by the air pump, the air needs to enter the internal unit of the air pump and then be output, and this process may cause a significant reduction in the dust content of the air, thereby making the detection result unable to reflect the actual dust concentration." The rapid extraction assembly 2 and the mixing, detecting and pre-tightening assembly 3 are specifically proposed;

[0037] In use, the rotation speed of the motor 8 is controlled by the gear control key 19 on the surface of the casing 1, thereby controlling the rate of air inflow. The air containing dust enters the interior of the intake pipe 5 through the bell mouth 4, and the air inside the intake pipe 5 quickly enters the interior of the outlet pipe 10 under the acceleration of the fan blade 9. The air inside the outlet pipe 10 is finally output to the interior of the collection box 11. After collection, the motor 8 is turned off to achieve the effect of quantitative detection. The air enters the interior of the concentration detector 16 through the conduit 15 to detect the dust concentration. Once the dust concentration in the air is greater than the predetermined value, the alarm 17 is controlled to achieve the alarm effect.

[0038] In order to make the detection more accurate, a bearing 12 and a rotating rod 13 are installed inside the collection box 11. The pneumatic fan blade 14 on the rotating rod 13 can rotate under the action of the air flow, thereby achieving the effect of air mixing and making the detection effect of the detection device more accurate.

[0039] Through the rapid extraction component 2 provided in the present utility model, the extraction component of the device only has the high-speed fan blade 9 installed inside the air hood 6, and the gas directly enters the interior of the rear dust collection box through the air hood 9, avoiding the problem of reduced concentration caused by the gas passing through a structurally complex air pump. In addition, the high-speed rotating fan blade 9 of the device can quickly collect the gas, avoiding the problem of dust settlement during the slow flow of the gas.
