In this way, the temperature and humidity in the box body 11 can be well adjusted, and the box body 11 does not need to be connected with the outside, so as to effectively avoid the overflow of formaldehyde. It should be noted that the structure of the main machine 21 and the heat exchange pipe 22 is similar to that of an air conditioner, the main machine 21 can be understood as an outdoor unit of an air conditioner, the heat exchange pipe 22 is a copper pipe and an indoor unit, a compressor, a heat dissipation fan 151, an expansion valve and other conventional structures are arranged in the main machine 21, and the valve is switched to make the high-temperature medium or low-temperature medium enter the heat exchange pipe 22.

[0031] The second sealing device 29 in the embodiment comprises a second sealing plate 291 arranged above the exhaust pipe 26, a second sliding rod 292 fixedly connected to the lower side of the second sealing plate 291 and arranged vertically, a second support rod 293 horizontally arranged on the inner wall of the exhaust pipe 26, and a limiting plate 294 arranged at the lower end of the second sliding rod 292; the second sliding rod 292 is slidingly connected to the second support rod 293, and the limiting plate 294 is arranged below the second support rod 293. Specifically, when the fan 27 is running, the air flow generated by the fan 27 lifts the second sealing plate 291, so that a gap is formed between the second sealing plate 291 and the end of the exhaust pipe 26, so that air can flow out through the gap; when the fan 27 stops running, the second sealing plate 291 is pressed on the exhaust pipe 26 again under the gravity of the second sealing plate 291, so as to seal the exhaust pipe 26.
[0032] The heat exchange assembly in the embodiment further comprises a water storage box arranged at the lower side of the box body 24, and a drain pipe 211 in communication with the lower side of the water storage box; the water storage box is in communication with the box body 24, and the end of the drain pipe 211 away from the water storage box extends outward through the side wall of the box body 11. Specifically, the water storage box and the drain pipe 211 have the following effects: one is to discharge the water generated by condensation in the box body 24, and the other is to add water to the box body 24 through the drain pipe 211 and the water storage box, so that the water in the box body 24 contacts the fins 23 or the heat exchange pipes 22, and then the water is heated by the high-temperature fins 23 and heat exchange pipes 22, and then the water vapor is sent into the box body 11 by the fan 27, so as to improve the humidity in the box body 11.
[0033] The air circulation device 15 in the embodiment comprises a fan 151 arranged in the box body 11, and the fan 151 and the heat exchange assembly are arranged on opposite sides of the box body 11. Specifically, the motor of the fan 151 can be arranged outside the box body 11, so that the temperature of the motor during operation can avoid affecting the temperature of the air in the box body 11 to a certain extent.
[0034] In summary, the formaldehyde purification effect test box of the net aldehyde plate material in the embodiment is used by placing the formaldehyde release source and the plate 16 in the box body 11 by opening the box door 12, then sealing the box body 11 by closing the box door 12, circulating the air in the box body 11 by using the air circulating device 15, making the formaldehyde uniformly distributed in the box body 11, detecting the formaldehyde concentration in the box body 11 by extracting part of the air in the box body 11 through the air guide pipe 13 for formaldehyde content detection at regular time, and calculating the formaldehyde absorption of the plate 16. In this process, the temperature and humidity in the box body 11 can be adjusted by the temperature and humidity adjusting device 20 to simulate the formaldehyde absorption of the plate 16 in different temperature and humidity environments. The temperature and humidity adjusting device 20 mainly generates hot medium or cold medium by the host 21 and conducts the hot medium or cold medium to the heat exchange pipe 22. The high temperature of the heat exchange pipe 22 can increase the temperature in the box body 11, and the low temperature of the heat exchange pipe 22 can make the moisture in the box body 11 condense on the heat exchange pipe 22, so as to reduce the temperature or humidity in the box body 11. In this way, the temperature and humidity in the box body 11 can be well adjusted, and the box body 11 does not need to be connected with the outside, so that the overflow of formaldehyde can be effectively avoided.
