The corner VOC gas sensor 30 and the corner resistance heating plate 31 are fixedly connected to the corner test chamber 28, and the inner wall of the corner test chamber 28 is a smooth surface.

[0035] The working principle of the VOC emission detection environment chamber of the present invention is as follows: First, when the present invention performs synchronous detection of corner areas, the controller 16 starts the pushing electric cylinder 32 inside the cabin body 1, and the pushing electric cylinder 32 pushes the support slot column 2 to move. At the same time, the cabin body 1 supports the supporting sleeve 33, and the supporting sleeve 33 provides stable supporting force for the pushing electric cylinder 32. The support slot column 2 drives the linkage bar 27 to move left, the linkage bar 27 drives the corner test cabin 28 to move left, the corner test cabin 28 drives the sealing corner strip 29 to move left, and the sealing corner strip 29 squeezes and seals at the corner position of the test material plate 15. The corner test cabin 28 performs a VOC release sealing test on the corner position of the test material plate 15, and then turns off the pushing electric cylinder 32 through the controller 16. At the same time, the controller 16 turns on the corner resistance heating plate 31 to heat the internal space of the corner test cabin 28, so that the VOC at the corner position of the test material plate 15 can be quickly released. For the movement direction described in the above paragraph, please refer to the attached Fig.11 The view orientation.

[0036] At the same time, when the present invention performs bilateral area synchronous detection, the micro motor 4 is started through the controller 16, and the micro motor 4 drives the linkage screw 3 to rotate, and the linkage screw 3 rotates stably inside the support slot column 2. At the same time, the linkage screw 3 rotates to drive the sleeve block 5 to move downward under the action of the thread transmission force, and the sleeve block 5 slides down along the inner wall of the support slot column 2. At the same time, the sleeve block 5 drives the two hinge blocks 6 to move downward synchronously, and the two hinge blocks 6 respectively drive the two hinge columns 7 to move downward synchronously, and the hinge column 7 drives the top end of the hinge sleeve rod 8 to move downward, and the hinge sleeve rod 8 drives the linkage shaft 9 to move, and the linkage shaft 9 drives the slot plate 10 to move, and the slot plate 10 drives the side detection cabin 11 to move closer to the test material plate 15.

[0037] The side detection chamber 11 drives the sealing side strip 12 to move closer to the test material plate 15. At the same time, the groove plate 10 drives the sleeve slider 18 to move, and the sleeve slider 18 slides along the inner wall of the guide frame 19, and at the same time, the sleeve slider 18 slides along the outer wall of the support rod 20. In this way, the sealing side strip 12 will fit on one side of the inner wall of the test material plate 15, and the other sealing side strip 12 will fit on the other side of the inner wall of the test material plate 15. The side detection chamber 11 realizes a closed detection of VOC release in the area on one side of the inner wall of the test material plate 15, and the other side detection chamber 11 also realizes a closed detection of VOC release in the area on the other side of the inner wall of the test material plate 15. At the same time, the controller 16 will turn on the side resistance heating plate 13, and the side resistance heating plate 13 will heat the internal area of ​​the side detection chamber 11.

[0038] At the same time, when the present invention performs synchronous detection of the bottom triangular partition, the controller 16 starts the lower pressure electric cylinder 22 at the same time, and the guide frame 19 supports the sleeve plate 21, and the lower pressure electric cylinder 22 drives the bottom triangular detection cabin 23 to move down, and the bottom triangular detection cabin 23 makes the sealing bottom strip 24 move down, and the sealing bottom strip 24 is sealed and attached to the bottom end position of the inner wall of the test material plate 15, and the bottom triangular detection cabin 23 can realize synchronous sealing VOC release detection of the bottom end area of ​​the inner wall of the test material plate 15. Then the bottom resistance heating plate 25 is turned on by the controller 16, and the bottom resistance heating plate 25 realizes heating operation on the bottom end area of ​​the inner wall of the test material plate 15.

[0039] Finally, when the present invention performs synchronous detection, the VOCs released from both sides of the inner wall of the test material plate 15 will enter the two side detection chambers 11 respectively, and the VOC release amount will be sensed by the side VOC gas sensor 14. At the same time, the VOCs released from the corners of the test material plate 15 enter the corner test chamber 28, so that the VOC release amount is sensed by the corner VOC gas sensor 30. At the same time, the VOCs released from the bottom end of the inner wall of the test material plate 15 enter the bottom triangular detection chamber 23, and the VOC release amount is sensed by the bottom VOC gas sensor 26. It is possible to realize synchronous VOC release detection in different regions at the positions on both sides of the inner wall of the test material plate 15, at the bottom end of the inner wall of the test material plate 15, and at the corners of the test material plate 15, and the detected VOC release amounts are all displayed on the display screen 17, greatly improving the detection efficiency.
