A plug interface 4 is opened on the side wall of the collecting chamber 104, and a sampling plate 401 is movably connected inside the plug interface 4. A second filter membrane 402 is arranged on the sampling plate 401. The collecting chamber 104 is connected to the inside of the handle 5, and a fan 502 is arranged inside the handle 5. An air outlet 501 is opened at the bottom of the handle 5, and the fan 502 is electrically connected to the PLC controller 7.

[0023] Specifically, a ventilation net 102 is provided at the air inlet 101; the ventilation net 102 has relatively large meshes to block relatively large debris such as weeds, paper scraps, etc., and will not hinder the passage of dust.

[0024] Specifically, rubber strips 403 are provided on both sides of the sampling plate 401 ; the elasticity of the rubber strips 403 can ensure that the sampling plate 401 can be firmly clamped inside the housing 1 .

[0025] Specifically, a protective net 503 is provided at the air outlet 501 ; the protective net 503 can protect the fan 502 from being damaged by the outside world and prevent the fingers of the staff from accidentally entering the air outlet 501 .

[0026] Specifically, it also includes a hand guard 8, the upper end of the hand guard 8 is connected to the bottom of the shell 1, and the lower end of the hand guard 8 is connected to the bottom end of the handle 5; the staff's hand is located inside the hand guard 8, which can play a protective role, facilitate the staff to grasp, and prevent the device from falling.

[0027] Specifically, it also includes an LED explosion-proof lamp 9, which is arranged below the air inlet 101 and is electrically connected to the battery 6 and the PLC controller 7; when visibility is low, the LED explosion-proof lamp 9 can provide lighting for the staff, and the LED explosion-proof lamp 9 can reduce the possibility of dust explosion.

[0029] Specifically, the pore size of the second filter membrane 402 is smaller than that of the first filter membrane 10; the first filter membrane 10 blocks large dust particles, and the second filter membrane 402 is used to collect small dust particles, which are classified and stored for subsequent detection.

[0030] The use process of the utility model is as follows:

[0031] First, insert the clean collection frame 201 into the collection tank 2, insert the clean sampling plate 401 into the plug port 4, then start the fan 502, and the outside air is sucked in from the air inlet 101. Large debris is blocked by the ventilation net 102, and the dust-containing gas is filtered through the separation chamber 103 and the collection chamber 104 and then discharged through the air outlet 501;

[0032] In the separation chamber 103, the outside air is blocked by the baffle 3 and passes from the top of the collection frame 201 to the collection chamber 104. During this process, the first filter membrane 10 blocks the larger dust particles and drops them into the collection frame 201. After the filter stops working, the dust remaining on the filter screen 10 will fall into the collection frame 201.

[0033] In the collection chamber 104, the second filter membrane 402 blocks and collects smaller dust particles;

[0034] After the collection is completed, the collection frame 201 and the sampling plate 401 are taken out and transferred to the laboratory for testing.
