[0033] Specifically, the hollow ring 3, as one of the key supporting structures of the entire device, is cleverly designed to have a series of U-shaped plates 14 fixedly connected to it on all sides on the right side. These U-shaped plates 14 not only provide a stable support surface, but also cleverly integrate the rotation mechanism. On the inner side of the U-shaped plate 14, the shaft block 13 is rotatably connected through a precise bearing structure. On the right side of the interior of the hollow tank 1, there are multiple card holes 21 evenly distributed. These card holes 21 are specially designed to match the buckle 15, ensuring the accuracy and stability of the installation process. On the right side of the interior of the hollow tank 1, there are multiple card holes 21 evenly distributed. These card holes 21 are specially designed to match the buckle 15, ensuring the accuracy and stability of the installation process. This fixed plate 18 not only enhances the structural strength of the hollow tank 1, but also provides a solid foundation for the installation of other accessories or equipment.

[0034] Please refer to the attached Figure 4 - Attachment Figure 5The adjusting mechanism 2 includes a threaded column 203, the outer wall of the threaded column 203 is threadedly connected to the bottom of the outer wall of the hollow tank 1, the bottom of the threaded column 203 is fixedly connected to the lifting rod 202, the outer wall of the lifting rod 202 is slidably connected to the hollow rod 201, the outer walls of the hollow rod 201 and the lifting rod 202 are provided with holes 207, the inner side of the hole 207 is threadedly connected with a threaded knob 206, the bottom of the hollow rod 201 is fixedly connected to the threaded column 204, the bottom of the threaded column 204 is provided with a top plate 7, the left and right sides of the top of the top plate 7 are provided with threaded holes 205, the inner side of the threaded hole 205 is threadedly connected to the outer wall of the threaded column 204, the top left side of the top plate 7 is fixedly connected with an illuminating lamp 10, and the left side of the top plate 7 is connected with a heat sink 17;

[0035] Specifically, by using the threaded column 203 as one of the key components of the adjustment mechanism 2, its design cleverly achieves a stable connection with the bottom of the hollow tank 1. Through the threaded structure of the outer wall, the threaded column 203 can be easily screwed into the reserved threaded hole 205 at the bottom of the hollow tank 1 to ensure the tightness and stability of the connection. This design is not only easy to install, but also can be quickly disassembled when necessary, which is convenient for maintenance and repair, and further enhances the connection stability between the lifting rod 202 and the hollow rod 201 to lock the current position of the lifting rod 202. The threaded knob 206 is tightly screwed into the hole 207 by means of a threaded connection. When the height of the lifting rod 202 needs to be fixed, it only needs to tighten the threaded knob 206 to achieve a stable lock.

[0037] Specifically, the hollow tank 1 is used as the main body of the entire device, and the top of its outer wall is cleverly connected with a ventilation pipe 22. The design of the ventilation pipe 22 not only ensures the smoothness of air circulation inside the hollow tank 1, thereby ensuring that the internal equipment or stored items are in the best state, but the opening position and size of the ventilation pipe 22 are also carefully calculated to balance the ventilation effect and the need to prevent external impurities from entering. The design of the handle 11 conforms to the principles of ergonomics, and the grip is comfortable and stable, so that the user can easily lift or push the hollow tank 1. The capacity and type of the battery 5 are selected according to the actual needs of the device to ensure that sufficient power support can be provided for the internal equipment or external accessories for a long time.

[0038] Working principle: When the fan needs to be used for a long time, first fix the hollow tank 1 and the hollow ring 3, then move the shaft block 13 upward along the inner side of the U-shaped plate 14, rotate with the buckle 15, and at the same time detach from the outer wall of the card plate 16, contact the filter 4 and the inner side of the hollow tank 1 to engage, then slowly move the card block 12 fixedly connected to the filter 4 from the inner side of the card hole 21, so that the filter 4 can be taken out and cleaned, so the locking device is used to realize the filter 4 that is easy to maintain and replace, and at the same time, it is convenient for operators to quickly disassemble and assemble the filter 4, reducing downtime and maintenance costs, thereby meeting the needs of users:

[0039] After that, the hollow rod 201 is fixed to the threaded column 204, and the threaded hole 205 opened on the top plate 7 is threadedly connected, and then the lifting rod 202 is fixed to the threaded column 1 203, and the threaded connection is made to the bottom of the outer wall of the hollow tank 1 through the threaded column 1 203. When all the installation is completed, the lifting rod 202 is inserted into the inner side of the hollow rod 201, and the height of the ventilator is adjusted to avoid moisture-proof. When the appropriate height is reached, the threaded knob 206 is threadedly connected to the inner side of the corresponding hole 207 for limiting. Therefore, it is effectively ensured that the height of the ventilator can be adjusted according to the needs of the operator when in use, and at the same time it has a moisture-proof effect, and the use effect is relatively wide, which meets the needs of the operator.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
