[0021] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments described herein.

[0022] like Figures 1-3 As shown, a rapid temperature and humidity test chamber with an air duct guiding structure includes a chamber body 1; and also includes: A support partition 3 is fixedly installed inside the housing 1, and the housing 1 is divided into an upper cavity and a lower cavity by the support partition 3. The air duct guide structure 5 is disposed in the upper cavity. The air duct guide structure 5 includes multiple bottom covers 505 for blowing air, and each of the multiple bottom covers 505 is provided with a vertical telescopic tube at its top. The air duct guide structure 5 is connected to a hot and humid air mechanism 2, which is used to blow hot and humid airflow into the air duct guide structure 5. The material carrier 4 is a plurality of such material carrier 4, and the plurality of material carrier 4 are respectively disposed below the plurality of bottom covers 505; the material carrier 4 is fixedly installed on the support partition 3.

[0023] The airflow guide structure 5 guides the hot and humid airflow to be blown out from under multiple bottom covers 505, thereby targeting the objects in multiple material frames 4 and allowing the hot and humid airflow to directly reach the objects. Furthermore, the bottom covers 505 are mounted on the airflow guide structure 5 via telescopic fittings. The height of the bottom covers 505 can be adjusted by extending and retracting the fittings. During object testing, the bottom covers 505 are adjusted to a low position, close to the material frames 4, to further facilitate direct blowing of hot and humid airflow onto the objects in the material frames 4. Figure 1 As shown; when loading and unloading objects in the loading frame 4, by adjusting the bottom cover 505 to a high position, there is sufficient distance between the bottom cover 505 and the loading frame 4, which does not affect the loading and unloading of objects in the loading frame 4, as shown. Figure 2 As shown.

[0024] Humidity and temperature sensors are installed inside the loading frame 4 to monitor the temperature and humidity of the environment near the items in real time.

[0025] like Figures 1-2 As shown, the supporting partition 3 has several evenly distributed ventilation slots 301, and the upper cavity and the lower cavity are connected through the ventilation slots 301. The ventilation slots 301 connect the upper and lower cavities, allowing the hot and humid airflow to enter the lower cavity from the upper cavity and the ventilation slots 301 after hot and humid airflow is blown onto the objects in the loading frame 4. Ventilation slots 301 are located at the bottom and outer sides of the loading frame 4.

[0026] The hot and humid air mechanism 2 includes a body 201; inside the body 201, from bottom to top, are arranged a fan, a heating wire, and an evaporator heater (not shown in the figure). The fan, heating wire, and evaporator heater are used to generate a hot and humid airflow.

[0027] like Figure 1 As shown, the hot and humid air mechanism 2 also includes a return air hood 202 that is fixedly connected to the bottom of the body 201. The bottom of the return air hood 202 is fixedly connected to a return air pipe 203. The return air pipe 203 is fixedly connected to the side wall of the housing 1 and is connected to the lower cavity.

[0028] The top of the body 201 is fixedly connected to an air outlet hood 204, the top of the air outlet hood 204 is fixedly connected to an air outlet pipe 205, and the portion of the air outlet pipe 205 located at the bottom of the housing 1 is fixedly connected to a plurality of equally spaced air outlets 206.

[0029] The hot and humid air mechanism 2 operates as follows: the fan blows air, and the airflow is heated by the heating wire and humidified by the evaporation heater to form a hot and humid airflow. The hot and humid airflow is guided by the air outlet hood 204 and the air outlet pipe 205, and discharged from multiple air outlets 206, and enters the air duct guide structure 5 for testing.

[0030] After the hot and humid airflow enters the lower cavity, the fan draws the airflow from the lower cavity and returns it to the machine body 201 through the return air pipe 203 and return air cover 202 to achieve recycling and avoid the airflow in the lower cavity being directly discharged, which would cause waste.

[0031] like Figure 1 As shown, the air duct guide structure 5 also includes an upper cover 501, which is fixedly installed on the top inner wall of the housing 1. The upper cover 501 is connected to the air outlet 206. Multiple guide covers 502 are fixedly connected to the bottom of the upper cover 501. The guide covers 502 are connected to the bottom cover 505 through telescopic pipes.

[0032] The telescopic fitting includes a first duct 503 and a second duct 504. The top end of the first duct 503 is fixedly connected to the bottom of the guide shroud 502. The outer wall of the second duct 504 is slidably sleeved with the inner wall of the first duct 503, and a sealing ring that fits against the inner wall of the first duct 503 is sleeved on the top end of the second duct 504. A bottom cover 505 is fixedly sleeved on the bottom end of the second duct 504. By sliding the second duct 504 along the first duct 503, the length of the second duct 504 extending from the first duct 503 can be adjusted, thereby adjusting the height of the bottom cover 505.

[0033] After being discharged through the air outlet 206, the hot and humid airflow enters the upper cover 501 of the air duct guide structure 5, and is then diverted by the guide cover 502 into multiple first air ducts 503. Next, it enters the lower cover 505 through the second air duct 504, and finally exits from below the lower cover 505. Through this structure, the hot and humid airflow is guided and diverted to multiple material carrying frames 4.

[0034] like Figures 1-3 As shown, a crossbar 506 is fixedly installed on the second air duct 504 of the multiple telescopic pipe fittings; iron sliders 507 are fixedly installed on both ends of the crossbar 506, and a vertical sliding groove 101 is provided on the inner side wall of the box body 1, and the iron sliders 507 are slidably connected to the vertical sliding groove 101.

[0035] like Figures 1-2 As shown, a magnetic block 102 for the magnetic slider 507 is fixedly fitted and installed at the top of the vertical sliding groove 101. The magnetic block 102 can be an electromagnet.

[0036] The horizontal bar 506 is moved up and down to drive the second air duct 504 to move up and down. During the up and down movement, the iron slider 507 and the vertical slide groove 101 provide guidance.

[0037] When the bottom cover 505 is adjusted to the lowest position, the iron slider 507 contacts the bottom wall of the vertical sliding groove 101 to maintain the lowest position state; when the bottom cover 505 is adjusted to the highest position, the iron slider 507 contacts the magnetic block 102, and the magnetic block 102 magnetically limits the iron slider 507 to maintain the bottom cover 505 in the highest position state.

[0038] The front of the box 1 is provided with an entrance and exit, and a door (not shown in the figure) is installed on the entrance and exit of the box 1. The door is used to open and close the entrance and exit on the front of the box 1; the entrance and exit are used to pick up and put down objects in the loading frame 4.

[0039] The rapid temperature change and humidity test chamber proposed in this utility model is suitable for testing small items.

[0040] In practice, the upper cover 501 is fixed to the box 1 with screws and bolts and can be disassembled; the crossbar 506 and the iron slider 507 are also installed in a detachable manner, such as the crossbar 506 having a mounting plate at the end, and the mounting plate being fixed to the iron slider 507 with screws and bolts.

[0041] With the above-mentioned detachable design, when testing large items inside the housing 1, the air duct guide structure 5 can be removed from the housing 1 to meet the testing requirements of large items.

[0042] This utility model is not limited to the above-described embodiments. Any changes in its shape or structure fall within the protection scope of this utility model. The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
