DETAILED DESCRIPTION

[0017] like Figures 1 to 4As shown, a temperature and humidity coupled environmental simulation box disclosed in the present invention includes a sealed box body 1, a temperature sensor 2 and a humidity sensor 3 installed in the box body 1, and the temperature sensor 2 and the humidity sensor 3 are connected to a controller at the same time; the box body 1 is a sealed box body 1, and the whole is in a rectangular shape. The temperature sensor 2 is used to detect the temperature in the box body 1, and the humidity sensor 3 is used to detect the humidity in the box body 1. It can be understood that the temperature sensor 2 and the humidity sensor 3 can transmit the detected temperature signal and humidity signal to the controller, and the controller can control the temperature control device 13 and the humidity control device to operate, so that the temperature and humidity are adjusted.

[0018] The left rotating plate 4 and the right rotating plate 5 are rotatably arranged on the two side walls of the box body 1, respectively. The left rotating plate 4 and the right rotating plate 5 are circular and are rotatably matched with the box body 1 through sealing rings. The left rotating plate 4 and the right rotating plate 5 are connected through 6 support pipes 6, one end of the support pipe 6 is fixedly connected to the left rotating plate 4, and the other end of the support pipe 6 is extended from the right rotating plate 5 and connected to the return pipe 7, which is also connected to the box body 1, and a fan 8 is installed in the return pipe 7.

[0019] A plurality of through holes 9 are evenly formed on the tube wall of the support tube 6, and a piston 10 and a plurality of elastic dehumidification boxes 11 are slidably provided inside the support tube 6. When the humidity inside the box body 1 needs to be reduced, the fan 8 can be started to suck the gas inside the box body 1 into the support tube 6 through the through holes 9, and after being dried by the elastic dehumidification boxes 11, the gas is discharged into the inside of the box body 1 through the lower end of the return pipe 7.

[0020] Furthermore, a displacement driving device is installed on the support tube 6 to drive the piston 10 to move and compress the elastic dehumidification box 11 to the right end. The displacement driving device can adopt a cylinder or a hydraulic cylinder. An elastic supporting device 12 is installed between two adjacent elastic dehumidification boxes 11; a temperature control device 13 is also installed at the bottom of the box body 1. The temperature control device 13 can adopt a heating wire and a condenser. The fan 8, the displacement driving device and the control device are connected to the controller at the same time.

[0021] The working principle and process of the device of the present invention are as follows: 1.1. When it is necessary to keep the temperature and humidity in the box 1 at a lower level, the temperature control device 13 cools the temperature in the box 1 until the temperature reaches the required level, and then turns on the fan 8 to allow the gas to flow in a positive direction, sucking the gas in the box 1 into the support tube 6 from the through hole 9, and after being dried by the elastic dehumidification box 11, it is discharged into the inner side of the box 1 through the lower end of the reflux pipe 7 to start dehumidification. After the humidity reaches the standard, the fan 8 is turned off.

[0022] 1.2. When the humidity in the box 1 needs to be increased, the elastic dehumidification box 11 is compressed to the right end by the piston 10, and the elastic dehumidification box 11 is continuously compressed. Under the driving action of the fan 8, the water vapor in the elastic dehumidification box 11 can be driven to be released, thereby increasing the amount of water vapor in the box 1 and thus increasing the humidity. When the temperature in the box 1 needs to be increased, the temperature in the refrigeration box 1 can be controlled by the temperature control device 13 to increase.

[0023] In this embodiment, the temperature control device 13 includes a device body 14, which is detachably mounted at the bottom of the box 1, so that the entire temperature control device 13 can be easily disassembled and maintained. A vertical hole 15 is provided on the device body 14, and a semiconductor cooling plate 16 is horizontally mounted in the vertical hole 15. The semiconductor cooling plate 16 is sealedly mounted in the vertical hole 15. The semiconductor cooling plate 16 adopts the existing technology, and the cooling surface or heating surface of the semiconductor cooling plate 16 can be directed to the inner side of the box 1 by changing the electrode. A channel 17 is also provided in the device body 14, and the upper port of the channel 17 is flush with the upper surface of the semiconductor cooling plate 16, and the lower port of the channel 17 is located at the lower side of the semiconductor cooling plate 16; the semiconductor cooling plate 16 is supported by a bracket 18 mounted in the vertical hole 15, and a two-way fan 19 is also mounted on the bracket 18.

[0024] When it is necessary to lower the temperature in the box 1, the temperature in the box 1 can be adjusted by turning the cold surface of the semiconductor refrigeration plate 16 upwards. If the humidity needs to be adjusted at the same time, the solenoid valve in the channel 17 is opened, and the water vapor in the box 1 can condense on the cold surface of the semiconductor refrigeration plate 16 and then be discharged through the channel 17. This not only improves the speed of adjusting the temperature and humidity, but also saves energy. At this time, the two-way fan 19 can provide downward power to drive the water vapor to be discharged from the channel 17 in time.

[0025] When the temperature in the box body 1 needs to be increased, the two-way fan 19 provides power in the reverse direction. At this time, the hot side of the semiconductor cooling plate 16 faces upward, and the air at the upper port is heated and flows into the box body 1 at an accelerated speed, which can accelerate the temperature rise inside the box body 1.

[0026] In this embodiment, a slot 20 is provided on the device body 14 , and a fixed dehumidification box 21 is detachably installed in the slot 20 . The channel 17 passes through the fixed dehumidification box 21 , and moisture can be removed through the fixed dehumidification box 21 .

[0027] In this embodiment, a water storage tank 22 is provided on the top of the box body 1, and a nozzle 23 is connected to the water storage tank 22, and the nozzle 23 extends into the inner side of the box body 1. In order to further quickly increase the humidity in the box body 1, a humidifier 24 is also connected to the box body 1.

[0028] In this embodiment, a sealing door 25 is installed on the left rotating plate 4. By setting the sealing door 25, it can be used to install the product that needs to be tested. The right rotating plate 5 is connected to a rotation drive device 26. The rotation drive device 26 can drive the left rotating plate 4 and the right rotating plate 5 to rotate coaxially, which can improve the stability of the rotation.

[0029] In this embodiment, the displacement driving device includes a motor 27, a screw rod 28 connected to the output end of the motor 27, the motor 27 is fixed to the left rotating plate 4, the piston 10 is threadedly connected to the screw rod 28 and is slidably arranged on the support tube 6 through a track, and the elastic support device 12 includes a first spring, and the first spring is sleeved on the outside of the screw rod 28. The motor 27 drives the screw rod 28 to rotate, and the screw rod 28 can push the piston 10 to move rightward, thereby compressing the elastic dehumidification box 11 to the right end, and the control is more convenient.

[0030] In this embodiment, the elastic dehumidification box 11 includes two relatively arranged box covers 29, a second spring 30 for connecting the two box covers 29, and a bellows 31 for connecting the two box covers 29 together. The box covers 29 are provided with holes 32. The elastic dehumidification box 11 is filled with dehumidification particles 33. The particle size of the dehumidification particles 33 is larger than the diameter of the hole 32. The stiffness of the second spring 30 is greater than the stiffness of the first spring. The elastic dehumidification box 11 adopts the above structure. When the piston 10 pushes the elastic dehumidification box 11 to compress, the water vapor in the elastic dehumidification box 11 can be pressed out, thereby saving water resources, allowing the elastic dehumidification box 11 to be reused, and saving the use cost of the elastic dehumidification box 11.
