[0033] Specifically, the housing 1 is the main frame of the entire ventilation device, which is made of high-quality metal materials to ensure that the device structure is strong and corrosion-resistant. The fan 1 4 and the fan 2 5 are the main power sources of the device, responsible for generating a stable airflow. The fan 1 4 and the fan 2 5 are coaxial and have the same impeller direction. The motor 11 is connected to the threaded rod 7 through its output end to provide rotational power for the threaded rod 7. The threaded rod 7 is threadedly connected to the fan 2 5. When the motor 11 is started, the threaded rod 7 rotates, driving the fan 2 5 to move horizontally inside the housing 1. A slider 9 is fixed at the bottom of the fan 2 5, and a pulley 13 is provided at the bottom of the slider 9 to ensure that the fan 2 5 can move smoothly in the slide 10. The design of the pulley 13 effectively reduces the friction resistance during movement and improves the operating efficiency of the device. The slide 10 is the track for the movement of the fan 2 5, which is located at the bottom of the housing 1 to ensure that the fan 2 5 moves smoothly inside it. At the same time, the slide bar 8 serves as an additional support and guide device to ensure that the fan 2 5 does not shake or deviate during movement.

[0034] Reference Figure 1 , Figure 2 , Figure 3 The disassembly assembly includes a fixing groove 14, which is opened at the top of the casing 1. The top of the filter plate 2 is rotatably connected with a rotating ring 3, and the bottom of the rotating ring 3 is fixedly connected to a protrusion 17. Both sides of the outside of the protrusion 17 are movably connected with connecting rings 18. One side of the connecting ring 18 is fixedly connected with a connecting rod 20, and a spring 19 is sleeved on the outside of the connecting rod 20. A connecting groove 15 is opened at the top of the casing 1, and the other end of the connecting rod 20 is slidably connected to the inner wall of the connecting groove 15. The inside of the rotating ring 3 is slidably connected with an insertion rod 21, and the top of the insertion rod 21 is fixedly connected with a hanging rope 16, and the other end of the hanging rope 16 is fixedly connected to the top of the filter plate 2.

[0035] Specifically, the filter plate 2 is located inside the housing 1. The filter plate 2 can be easily removed or installed from the fixed groove 14 by rotating the ring 3. When the rotating ring 3 rotates, the protrusion 17 will move accordingly, thereby driving the connecting ring 18 and the connecting rod 20 to perform corresponding actions. The connecting ring 18 is connected to the protrusion 17 by a movable connection. When the protrusion 17 moves, the connecting ring 18 will move accordingly, thereby driving the connecting rod 20 to perform corresponding actions. The connecting rod 20 is one of the key parts of the disassembly assembly. It is connected to the connecting groove 15 by a sliding connection. When the connecting rod 20 moves. The spring 19 provides a reset force for the connecting rod 20. When the filter plate 2 is removed, the spring 19 will be compressed. When the filter plate 2 is reinstalled, the spring 19 will push the connecting rod 20 to reset, ensuring that the filter plate 2 can be tightly fixed in the fixed groove 14. The connecting groove 15 is a sliding track for the connecting rod 20. When the connecting rod 20 moves, it will slide inside the connecting groove 15. The plug rod 21 is used to lock the position of the rotating ring 3. When the plug rod 21 is inserted into the rotating ring 3, the position of the rotating ring 3 can be fixed. When the filter plate 2 needs to be removed, the rotating ring 3 can be unlocked by simply pulling out the plug rod 21, so that it can rotate freely. The design of the hanging rope 16 avoids the problem of the plug rod 21 being lost after being pulled out, thereby improving the safety and convenience of operation.

[0036] Working principle: When the motor 11 is started, it will drive the threaded rod 7 to rotate. Since the fan 25 is threadedly connected to the threaded rod 7, the threaded rod 7 will drive the fan 25 to move horizontally in the casing 1. When the fan 25 moves, it drives the pulley 13 to move on the inner wall of the slide groove 10, ensuring the smooth movement of the fan 25. Since the pulley 13 can roll smoothly, the slide rod 8 provides support and guidance for the fan 25, preventing the fan 25 from shaking or deviating during the movement. It is achieved that by adjusting the position of the fan 25, the flow of airflow can be optimized, thereby increasing the air volume and air pressure of the entire device, making this device more flexible.

[0037] When the filter plate 2 needs to be removed, first pull out the plug 21 to unlock the rotating ring 3 so that it can rotate freely. Then rotate the rotating ring 3 to drive the protrusion 17, the connecting ring 18 and the connecting rod 20 to perform corresponding actions. Under the compression force of the spring 19, the connecting rod 20 will slide along the sliding track of the connecting groove 15 until the connecting rod 20 is completely separated from the connecting groove 15, and the filter plate 2 can be easily removed from the fixed groove 14. When installing the filter plate 2, first place the filter plate 2 in the fixed groove 14, and then rotate the rotating ring 3. As the rotating ring 3 rotates, the protrusion 17 drives the connecting ring 18 and the connecting rod 20 to move. Under the reset force of the spring 19, the connecting rod 20 will slide along the sliding track of the connecting groove 15 until the other end of the connecting rod 20 is completely inserted into the connecting groove 15, and the filter plate 2 is tightly fixed in the fixed groove 14. Users can easily complete it through simple operations without complex tools or professional skills. Compared with the prior art that uses multiple bolts to fix, this convenient maintenance operation greatly reduces maintenance costs and time and improves equipment maintenance efficiency.
