[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1-5, the present utility model provides a technical solution: an internally circulating permanent magnet generator with adjustable air outlets, comprising a permanent magnet generator body 1, an installation base 2, a fixing plate 3, a fixing column 4, a spring 5, a limiting plate 6, a fixing bolt 7, a fixing cylinder 8, a dust-proof net 9, an installation plate 10, a connecting plate 11, a connecting column 12, a connecting sleeve 13, an adjusting mechanism 14, a baffle 15, a connecting block 16 and an adjusting column 17.

[0029] When using the internally circulating permanent magnet generator with adjustable air outlets, as Figure 1 and Figure 5 shown, first place the permanent magnet generator body 1 directly on the upper end of the installation base 2. The permanent magnet generator body 1 and the installation base 2 are installed and limited by the fixing plate 3. A fixing column 4 with a "T" - shaped structure is fixedly connected to the middle of the installation base 2. A, first pull down the limiting plate 6 with a "U" - shaped structure. The limiting plate 6 slides on the fixing column 4, and the limiting plate 6 squeezes the spring 5, causing the spring 5 to undergo elastic deformation. Then pull the fixing plate 3 towards the side close to the vertical central axis of the permanent magnet generator body 1. The fixing plate 3 slides between the permanent magnet generator body 1, so that the fixing plate 3 and the permanent magnet generator body 1 are engaged, and the permanent magnet generator body 1 and the installation base 2 are limited.

[0030] Then release the limiting plate 6. At this time, the spring 5 resumes elastic deformation and pushes the limiting plate 6 to slide upward, so that the upper end of the limiting plate 6 is inserted into the lower end of the fixing plate 3. The limiting plate 6 limits the fixing plate 3 and the permanent magnet generator body 1. Then rotate the fixing bolt 7 with a limiting function. The fixing bolt 7 is threadedly connected to both the limiting plate 6 and the installation base 2, further limiting the limiting plate 6 and the installation base 2, preventing loosening between the fixing plate 3 and the permanent magnet generator body 1. The fixing effect on the permanent magnet generator body 1 is good, and at the same time, it is convenient to disassemble and repair the permanent magnet generator body 1 when a fault occurs in the permanent magnet generator body 1.

[0031] As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a fixed cylinder 8 is fixedly connected to the right end of the permanent magnet generator body 1. A connecting plate 11 is fixedly connected to the middle of the fixed cylinder 8. The connecting plate 11 is in close contact with the dust-proof net 9, and the dust-proof net 9 is fixedly connected to the middle of the mounting plate 10. Through the setting of the dust-proof net 9, dust can be prevented from entering the permanent magnet generator body 1, with good dust-proof effect. At the same time, adjustment mechanisms 14 are provided at both the front and rear ends on the right side of the fixed cylinder 8. The adjustment mechanism 14 includes a baffle 15 with a blocking function, a connecting block 16 fixedly connected to the side of the baffle 15 away from the horizontal central axis of the fixed cylinder 8, and an adjustment column 17 with threads on its outer surface. According to the actual use situation, by rotating the adjustment column 17, the adjustment column 17 is rotatably connected to the connecting block 16, and at the same time, the adjustment column 17 is threadedly connected to the fixed cylinder 8. The adjustment column 17 drives the baffle 15 to move back and forth on the right side of the fixed cylinder 8 through the connecting block 16. At the same time, the adjustment mechanism 14 is in close contact with the fixed cylinder 8, so as to facilitate the adjustment of the air volume at the air outlet, with simple operation and very convenient use;

[0032] In addition, when there is too much dust on the dust-proof net 9, first rotate the adjustment column 17. The adjustment column 17 drives the baffle 15 to disengage from the fixed cylinder 8 through the connecting block 16. Then rotate the connecting sleeve 13 threadedly connected to the outer surface of the connecting column 12 to make the connecting sleeve 13 disengage from the connecting column 12. Then pull the mounting plate 10 to the right. The mounting plate 10 drives the dust-proof net 9 to disengage from the connecting plate 11, which is convenient for disassembling and cleaning the dust-proof net 9 to prevent the dust-proof net 9 from being blocked, with high practicality.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
