[0034] Reference Figure 2 - Figure 4 The outer wall of the left end of the cover plate 21 is fixedly connected with a sealing ring 23 to ensure the sealing effect of the cover plate 21. The sealing ring 23 is made of rubber material, and its outer wall is set to an arc surface to ensure that it can be smoothly inserted into the inner wall of the sealing groove 6. A sealing groove 6 is provided at the right end of the inner wall of the air outlet hole 5. The sealing ring 23 is adapted to the sealing groove 6 to ensure the sealing effect. The sealing ring 23 contacts the inner wall of the sealing ring 23. A slide groove 8 is provided on the left side of the inner wall of the air outlet hole 5 near the sealing groove 6 to ensure that the rectangular bar 28 can move back and forth stably. The inner wall of the slide groove 8 is slidably connected with a rectangular bar 28. By sliding the rectangular bar 28 on the inner wall of the slide groove 8, the stability of the forward and backward movement of the sleeve 27 can be ensured. The rectangular bar 28 is fixedly connected to the rear surface of the left end of the sleeve 27.

[0035] Reference Figure 3 - Figure 5 The inner wall of the sleeve 27 is provided with a thread groove 29, and the thread groove 29 has a certain curvature. When the slide bar 26 slides on its inner wall, it can drive the sleeve 27 to move forward or backward along its amplitude. An annular groove 210 is provided on the inner wall of the sleeve 27 near the left side of the thread groove 29. When the cover 21 is fully opened, the slide bar 26 will continue to slide on the inner wall of the annular groove 210, so that the cover 21 can remain continuously open when the blower 24 is in operation. The thread groove 29 is connected to the annular groove 210, and the slide bar 26 slides on the inner wall of the thread groove 29. The slide bar 26 slides on the inner wall of the annular groove 210. The inner wall of the sleeve 27 is fixedly connected with an inclined block 211. The inclined block 211 is provided. Block 211 ensures that when the fan 24 drives the rotating rod 25 to reverse, the sliding rod 26 can enter smoothly, and the inner wall of the threaded groove 29 causes the cover plate 21 and the sleeve 27 to move in opposite directions. The inclined block 211 is arranged at the connection between the threaded groove 29 and the annular groove 210. The driving assembly also includes a connecting plate 22, and the connecting plate 22 is fixedly connected to the upper surface of the right end of the cover plate 21. There are multiple groups of cover plates 21 and sealing rings 23. Multiple groups of cover plates 21 and sealing rings 23 contact the inner wall of the right end of the air inlet 4. Multiple groups of cover plates 21 are fixedly connected to the upper surface of the connecting plate 22. Multiple groups of cover plates 21 and sealing rings 23 are arranged and connected through the connecting plate 22, which can ensure that the air inlet 4 and the air outlet 5 can be sealed and opened synchronously.

[0036] Working principle: When the box 1 needs to be ventilated and cooled, the fan 24 is started, and the rotation of the blades of the fan 24 drives the rotating rod 25 to rotate, and the sliding rod 26 on the rotating rod 25 rotates accordingly. The sliding rod 26 slides in the thread groove 29 on the inner wall of the sleeve 27, and at the same time, the sleeve 27 moves forward along the outer wall of the rotating rod 25 along the curvature of the thread groove 29. In addition, the sleeve 27 slides in the slide groove 8 through the rectangular bar 28 to ensure the stability of the movement.

[0037] The sleeve 27 drives the cover plate 21 to move forward, so that the sealing ring 23 is moved out of the sealing groove 6, opening the air outlet 5. At the same time, the multiple groups of cover plates 21 connected by the connecting plate 22 move synchronously, opening the air inlet 4, realizing the exchange of air inside the box body 1 with the outside world, achieving the purpose of ventilation and cooling.

[0038] When the cover 21 is fully opened, the slide bar 26 enters the annular groove 210 and continues to slide, so that the cover 21 remains open when the fan 24 is working. When the ventilation and cooling are completed, the blades of the fan 24 are controlled to rotate in the opposite direction, and the rotating rod 25 drives the slide bar 26 to rotate in the opposite direction. After the slide bar 26 contacts the inclined block 211, it enters the threaded groove 29 along the inclined block 211, and the sleeve 27 drives the cover 21 to move backward. The sealing ring 23 is re-engaged in the sealing groove 6 to achieve sealing of the air inlet 4 and the air outlet 5, ensuring that the temperature and humidity inside the box body 1 are not affected by the outside world.

[0039] The filter plate 31 can protect the air inlet 4 to prevent external dust from entering the interior of the box 1 and contaminating the tea. When the filter plate 31 needs to be replaced, the bolts on its front surface can be turned down, and then the filter plate 31 can be pulled out from the right end of the front surface of the box 1 through the handle 32, which makes it convenient to clean or replace the filter plate 31.
