[0022] In the inner tank 2 of this embodiment, at least two detachably mounted partitions 3 are arranged from top to bottom. Specifically, the ends of the partition 3 extend in a direction perpendicular to the plane where the partition 3 is located to form a card block 32, and a plurality of guide grooves 21 spaced from top to bottom are symmetrically arranged on the inner walls of the inner tank 2 on both sides. The cross-sectional shape of the guide groove 21 is adapted to the card block 32, and the card block 32 can be slidably engaged in the guide groove 21, thereby realizing that the partition 3 can be slidably engaged in the above-mentioned guide groove 21. One end of the guide groove 21 close to the cabinet door is set through, so that the partition 3 is separated from the guide groove 21. At the same time, a plurality of ventilation grooves 31 are arranged on the partition 3 at intervals, which penetrate up and down, so as to facilitate the free circulation of air. When in use, the appropriate number of partitions 3 can be selected according to the size of the device to be shielded, and the partition 3 can be inserted into the guide groove 21 at the appropriate position. When the partition 3 needs to be replaced or removed, the partition 3 only needs to be directly pulled out from the guide groove 21. In addition, a baffle 33 is provided on the side of the partition 3 close to the cabinet door. The baffle 33 protrudes from the surface of the partition 3. On the one hand, it can be used as a handle to facilitate the user to hold and push the partition 3.

[0023] One side of the inner liner 2 of the present embodiment is provided with an air outlet 23 connected to the cavity 7, and at least two air outlets 23 are spaced apart from each other from top to bottom, and a wind shield 5 is correspondingly provided at each air outlet 23. The wind shield 5 is covered on the air outlet 23, and at the same time, the wind shield 5 is slidably connected to the side wall of the inner liner 2. The wind shield 5 is driven and connected by a driving mechanism 8, and the driving mechanism 8 drives the wind shield 5 to move along the side wall of the inner liner 2 to open or close the air outlet 23. Specifically, guide rails 22 are respectively provided on the left and right sides of the air outlet 23 on the side wall of the inner liner 2, and the length of the guide rails 22 is greater than the maximum moving distance of the wind shield 5. Matching slide grooves are respectively provided at corresponding positions on both sides of the wind shield 5, and the wind shield 5 is slidably connected to the guide rails 22 through the slide grooves. With this structure, when the wind shield 5 moves, it can guide the wind shield 5 to ensure that the wind shield 5 moves more smoothly. In addition, if Figure 4 As shown, the upper and lower ends of the air supply port 23 are respectively provided with protruding baffles, and the baffles and the guide rails 22 are distributed perpendicular to each other. The upper and lower ends of the wind shield 5 are respectively provided with matching sealing convex strips.

[0024] The driving mechanism 8 includes a driving motor 81, a transmission screw 82 and a moving block 83. Both ends of the transmission screw 82 are rotatably mounted on the side wall of the inner liner 2. The axis of the transmission screw 82 is parallel to the axis of the guide rail 21. The transmission screw 82 is rotatably mounted in a bearing connection manner in the prior art. One end of the transmission screw 82 is fixedly connected to the output end of the driving motor 81. The moving block 83 is threadedly sleeved on the outside of the transmission screw 82, and one end of the moving block 83 is fixedly connected to the windshield 5 (such as Figure 4 When the driving motor 81 is started, the driving screw 82 is driven to rotate, thereby driving the moving block 83 to move axially along the driving screw 82, thereby driving the wind shield 5 to move axially along the driving screw 82, that is, driving the wind shield 5 to move along the length direction of the guide rail 22, thereby realizing the closing or opening operation of the wind shield 5 on the air outlet 23.

[0025] In this embodiment, each air outlet 23 is provided with a fan 9, which is mounted on the inner wall of the housing 1, and the air outlet direction of the fan 9 is directly facing the air outlet 23. When the fan 9 is started, the cold air in the cavity 7 can be quickly blown to the air outlet 23 so that the cold air quickly enters the inner tank 2. The cooling efficiency of the area corresponding to the air outlet 23 is greatly accelerated. At the same time, a ventilation grille 11 for ventilation is also provided on the side wall of the inner tank 2 of this embodiment, which plays a ventilation role and balances the internal and external air pressure of the inner tank 2.

During use, the heat generated by the device to be shielded will cause the temperature inside the inner tank 2 to rise, so the refrigerator 6 will also start to produce cold air, and the cold air circulates in the cavity 7, cooling the inner tank 2 from the outside of the inner tank 2; when the temperature detector measures that the temperature of a certain area is higher than that of other areas, the information is fed back to the control screen, and then the user controls the windshield 5 of the corresponding area to move, and then opens the corresponding air outlet 23, and starts the corresponding fan 9 at the air outlet 23, so as to promote the cold air to quickly pass through the air outlet 23 into the corresponding area inside the inner tank 2, and realize directional and fixed-point cooling. When the temperature of the corresponding area is consistent with that of other areas, the fan 9 is controlled to stop, and the windshield 5 is controlled to reset and cover the air outlet 23.

[0028] The utility model provides a constant temperature and humidity shielding cabinet, which realizes fixed-point and directional cooling treatment of the interior of the inner tank 2 by setting an air supply port 23 and a movable wind shield plate 5, thereby ensuring that the temperature inside the inner tank 2 is uniform and consistent; and when the heat generated by the shielded equipment in the inner tank 2 is large, resulting in a decrease in the cooling effect, the cooling can be accelerated by opening the air supply port 23, thereby improving the cooling efficiency, ensuring that the temperature value inside the inner tank 2 is stable, achieving a constant temperature effect, and under a constant temperature environment, the humidity in the air is also relatively stable, thereby achieving the purpose of constant temperature and humidity.
