DETAILED DESCRIPTION

[0028] The following description is only the preferred embodiment of the present application, and does not limit the protection scope of the present application.

[0029] Embodiment, see Figures 1 to 5 As shown: the present application discloses a kind of temperature and humidity regulation test equipment, temperature and humidity regulation test equipment includes rack 10, temperature and humidity control box 20 and gas flow component 30 installed in rack 10.Rack 10 is frame structure, and different cavities or channels are formed by partition structure in the inside of rack 10.It is separated, wherein rack 10 includes temperature control cabin 12 and test cabin 11 communicated with temperature control cabin 12.Temperature control cabin 12 and test cabin 11 are separated by plate structure, and through hole is provided on the partition to communicate temperature control cabin 12 and test cabin 11.As preferred, test cabin 11 is located above temperature control cabin 12, to guide air flow from bottom to top into test cabin 11.

[0030] Temperature and humidity control box 20 is communicated with temperature control cabin 12, for adjusting the temperature and humidity of air flow into temperature control cabin 12.Temperature and humidity control box 20 is generator for generating temperature and humidity gas, which forms temperature and humidity gas with adjustable temperature and humidity by heating evaporation, ultrasonic evaporation and the like.Air flow generated by fan assembly 32 sends temperature and humidity gas into temperature control cabin 12, and then into test cabin 11 through temperature control cabin 12.

[0031] Gas flow component 30 includes circulation channel 31 and fan assembly 32 in circulation channel 31, and fan assembly 32 drives directional flow of gas in circulation channel 31.Circulation channel 31 is tubular channel structure fixed to rack 10, one end of circulation channel 31 is communicated with temperature control cabin 12, and the other end is communicated with temperature and humidity control box 20, and temperature control cabin 12, test cabin 11, circulation channel 31 and temperature and humidity control box 20 form an internal closed air flow internal circulation channel 31.

[0032] Further, the gas flow component 30 further comprises an air inlet channel 34 and an air outlet channel 33 in communication with the circulation channel 31, and a switching assembly 35 movably connected to the circulation channel 31, the air outlet channel 33 and the air inlet channel 34 are both in communication with the atmosphere, and the switching assembly 35 movably controls the opening and closing of the air outlet channel 33 and the air inlet channel 34 with the circulation channel 31. When the switching assembly 35 closes the air inlet channel 34 and the air outlet channel 33, the air circulation channel 31 is an internal circulation channel 31 structure, and the fan assembly 32 drives the air flow in the air circulation channel 31. When the switching assembly 35 opens the air inlet channel 34 and the air outlet channel 33, the air inlet channel 34, the circulation channel 31, the temperature control cabin 12, the test cabin 11, the temperature and humidity control box 20 and the air outlet channel 33 form an open air circulation channel 31.

[0033] The temperature and humidity adjustment test equipment has an internal air circulation channel formed by the temperature and humidity control box 20, the temperature control cabin 12, the test cabin 11 and the circulation channel 31, and the air flow and the temperature and humidity in the test cabin 11 are accurate. After the test in the test cabin 11 is completed, the air inlet channel 34 and the air outlet channel 33 are opened, so that the air flow enters the temperature and humidity control box 20, the temperature control cabin 12, the test cabin 11 and part of the circulation channel 31 from the air inlet channel 34 and is discharged from the air outlet channel 33 to form an external circulation air flow channel, which quickly adjusts the temperature and humidity in the test cabin 11 to achieve adjustment for further testing, and the equipment utilization rate is high.

[0034] As shown in Figures 3 to 5 The switching assembly 35 controls the opening and closing of the air outlet channel 33 and the air inlet channel 34, wherein the switching assembly 35 can separately control the opening and closing of the air outlet channel 33 and the air inlet channel 34. For example, the switching assembly 35 comprises an air outlet valve installed on the air outlet channel 33 and an air outlet driving member connected to the air outlet valve, and the air outlet driving member drives the air outlet valve to rotate to open and close the air outlet channel 33. The switching assembly 35 controls the opening and closing of the air inlet channel 34 in a similar manner, which can be understood by referring to the structure of the air outlet valve and the air outlet driving member, and will not be described here.

[0035] The reversing assembly 35 controls the opening and closing of the air outlet passage 33 and the air inlet passage 34. The reversing assembly 35 can be linked to control the opening and closing of the air outlet passage 33 and the air inlet passage 34. In an embodiment, the reversing assembly 35 includes a guide vane 352 rotatably connected to the circulation passage 31 and a reversing drive 351 connected to the guide vane 352. The reversing drive 351 drives the guide vane 352 to rotate to synchronously open or close the air outlet passage 33 and the air inlet passage 34. Specifically, the reversing drive 351 drives the guide vane 352 to rotate in a first direction, and the guide vane 352 rotates to close the air outlet passage 33 and the air inlet passage 34, so that the air outlet passage 33 and the air inlet passage 34 are simultaneously closed. The reversing drive 351 drives the guide vane 352 to rotate in a second direction opposite to the first direction, and the guide vane 352 rotates to connect the air outlet passage 33 and the air inlet passage 34 to the circulation passage 31, respectively. The air outlet passage 33 and the air inlet passage 34 are separated by the guide vane 352, so that the air flow inside the circulation passage 31 is converted to the air flow outside the circulation passage 31. The temperature and humidity test conditions in the test chamber 11 are quickly reset to meet the test conditions, and the utilization rate of the equipment is multiplied.

[0036] Further, the reversing assembly 35 includes a first stroke detection member 353 and a second stroke detection member 354 spaced apart and installed in the circulation passage 31. The first stroke detection member 353 and the second stroke detection member 354 can be set as stroke switches, photoelectric switches, Hall sensors, etc. to detect the activity stroke of the guide vane 352. The first stroke detection member 353 and the second stroke detection member 354 are used to limit the rotation range of the guide vane 352, thereby maintaining the closing performance of the guide vane 352 to the air inlet passage 34 and the air outlet passage 33.
