The interior of the climate chamber body 1 has multiple equidistantly distributed fixed plates 7. Each fixed plate 7 has a rectangular tube 12 around its four sides. Each rectangular tube 12 has a rectangular connecting rod 13 inside its cavity. Each rectangular connecting rod 13 has a driving component at its bottom, and each driving component is used to drive the formaldehyde panel 19 to move. By controlling the driving components, the operator can move the formaldehyde panel 19 up and down, thus ensuring better formaldehyde release and more accurate simulation when simulating the environment inside the climate chamber body 1.

[0024] In a specific embodiment, the drive assembly includes an electric motor 14, which is disposed on the inner wall of the rectangular tube 12. A rotating rod 15 is fixedly mounted on the output end of the electric motor 14, and a turntable 16 is fixedly mounted on the end of the rotating rod 15 away from the electric motor 14.

When the turntable 16 rotates, it drives the mounting block 17 to rotate. Therefore, the mounting block 17 drives the movable plate 18 to move up and down reciprocally. When the movable plate 18 moves up and down reciprocally, it drives the rectangular plug rod 13 to move up and down reciprocally.

When the detection is completed, the air in the climate box body 1 is extracted by the air extraction assembly 3, so that the inner wall of the climate box body 1 does not contain formaldehyde.

[0029] The implementation principle of the formaldehyde release amount test climate box of the embodiment is as follows:

[0030] Firstly, the staff opens the sliding door 2 to place the formaldehyde plate 19 on the inner curved mounting plate 10, when the placement is completed, the staff closes the sliding door 2, and controls the heating assembly and humidity assembly 6 to operate, so as to simulate the environment of the formaldehyde plate 19 releasing formaldehyde (at this time, the electric motor 14 is driven to operate, when the electric motor 14 operates, it can drive the rotating rod 15 to rotate, so that the rotating disc 16 can be driven to rotate by the rotating rod 15, when the rotating disc 16 rotates, it can drive the mounting block 17 to rotate, so that the moving plate 18 can be driven to move up and down by the mounting block 17, when the moving plate 18 moves up and down, it can drive the rectangular plug-in rod 13 to move up and down, when the rectangular plug-in rod 13 moves up and down, it can drive the outer curved mounting plate 9 to move up and down, when the outer curved mounting plate 9 moves up and down, it can drive the inner curved mounting plate 10 to move up and down, so as to drive the formaldehyde plate 19 to move up and down, so as to ensure that the formaldehyde plate 19 can adapt to the environment when it is in the simulation environment of the climate box body 1), when the formaldehyde plate 19 releases a certain degree, at this time, the staff opens the valve, so that the formaldehyde can enter the formaldehyde detection assembly 4 through the connecting pipeline 5, so as to detect the content of the released formaldehyde by the formaldehyde detection assembly 4, when the detection is completed, at this time, the staff operates the air extraction assembly 3 to extract the gas in the climate box body 1, so as to ensure that the inner wall does not contain formaldehyde.
