When the screw rod 602 rotates, it can push the two sets of sliders 604 to make relative movement, and then drive the baffle plate 606 to move in the same direction along the trajectory of the slide rail 605 to open the air inlet pipe 4. After the detection is completed, it is necessary to rotate the rotating block 603 in the opposite direction to make the two sets of baffle plates 606 contact each other to cover the air inlet pipe 4, thereby protecting the air inlet pipe 4 when not in use, avoiding the air inlet pipe 4 from being damaged or broken, resulting in the air being unable to enter the VOC gas detector body 1 through the air inlet pipe 4.

The test result is convenient for detecting the concentration of volatile organic compounds in furniture panels. At the same time, the anti-slip strip 7 is provided to prevent the VOC gas detector body 1 from falling off the hand during use. After the test is completed, the rotating block 603 needs to be rotated in the opposite direction to make the two sets of baffles 606 contact each other to cover the air inlet pipe 4, thereby protecting the air inlet pipe 4 when not in use. Then, the connecting rod 503 needs to be pulled, and the connecting rod 503 drives the movable plate 504 to move along the trajectory of the movable groove 502, and compresses the reset spring 507. Plate 504 drives the fixed plate 505 to move in the same direction, and moves the fixed plate 505 away from the slots at the upper and lower ends of the connecting plate 506. Then, the filter 3 is taken out through the connecting plate 506 and the filter 3 is cleaned. When installing, the filter 3 is inserted into the jack on the side wall of the filter box 2, and the above steps are repeated.
