[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a high and low temperature test chamber with a built-in humidity compensation structure, including a high and low temperature test chamber body 10. A motor 4 is fixedly connected to the other side of the high and low temperature test chamber body 10, and a belt 5 is sleeved on one end of the motor 4 shaft. This structure can realize the automatic rotation of the plate frame 7, and use the rotation of the plate frame 7 to achieve uniform humidification inside the high and low temperature test chamber body 10. A groove is opened at the bottom of the plate frame 7, and a central plate 12 is set inside the groove. The central plate 12 of this structure can humidify the top of the product, thereby improving the efficiency of humidity compensation. The frame 7 is rotatably connected to the main body 10 of the high and low temperature test chamber. An annular pipe 11 is embedded within the frame 7, located outside the center plate 12. This structure, through the connection of the annular pipe 11 and the center plate 12, allows steam to pass through the vertical pipe 8. The center plate 12 is connected to the annular pipe 11, and the top of the center plate 12 is rotatably connected to the rotating shaft 6 via a bearing. This structure does not affect steam delivery or the rotation of the rotating shaft 6. A workbench 9 is installed inside the main body 10 of the high and low temperature test chamber, located directly below the center plate 12. This structure improves the uniformity of humidity distribution on the product on the workbench 9. The vertical pipes 8 are arranged in a circular, evenly spaced pattern around the bottom of the ring pipe 11. The lower end of the vertical pipes 8 is lower than the height of the workbench 9. This structure improves the uniformity of humidity compensation for the products on the workbench 9. A steam generator 3 and a temperature and humidity sensor 2 are installed on one side of the high and low temperature test chamber body 10. The temperature and humidity sensor 2 is used to detect the temperature and humidity inside the high and low temperature test chamber body 10. When humidity compensation is required, the steam generator 3 is activated. The steam generator 3 and the temperature and humidity sensor 2 can be controlled by a PLC. A steam delivery pipe 1 is connected to the top of the steam generator 3. The high and low temperature test chamber body 10 has a rotating shaft 6 connected to its inner wall. A plate frame 7 is fixedly connected to the top of the rotating shaft 6. A belt 5 is connected to the top of the rotating shaft 6. A motor 4 is connected to one side of the belt 5. A vertical pipe 8 and a center plate 12 are set at the bottom of the plate frame 7. Steam outlets are opened on the inner sides of both the vertical pipe 8 and the center plate 12. The top end of the steam conveying pipe 1 is inserted into the inner wall of the rotating shaft 6 and communicates with the vertical pipe 8 and the center plate 12. The motor 4 of this device can drive the belt 5 to drive the rotating shaft 6 to rotate. An appropriate amount of sealing cotton can be used to fill the gap between the steam conveying pipe 1 and the rotating shaft 6 to prevent steam leakage.

[0023] Working principle: When using the high and low temperature test chamber with built-in humidity compensation structure, the temperature and humidity sensor 2 first detects that the humidity inside the main body 10 of the high and low temperature test chamber is insufficient and compensation is needed. The steam generator 3 is turned on to generate steam, which enters the center plate 12 of the plate frame 7 through the steam delivery pipe 1. Then, part of the steam is sprayed out from the bottom of the center plate 12, and the other part is sprayed out through the inner side of the vertical pipe 8 on the outside of the center plate 12, thereby uniformly humidifying the products on the workbench 9. During the humidification process, the motor 4 drives the belt 5 to rotate, which in turn drives the rotating shaft 6 and the plate frame 7 to rotate, thereby enabling rapid humidity compensation inside the main body 10 of the high and low temperature test chamber and ensuring the quality of product testing.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
