[0024] Embodiment

[0025] As Figure 1-2 shown, a fan with adjustable rotation range proposed by the present utility model includes a main body 1, and also includes a front grille 20. The front grille 20 is slidably installed on one side of the main body 1. A plurality of fan blades 18 arranged in an equidistant circular arrangement are rotatably installed in the main body 1. An auxiliary mechanism for quickly disassembling and assembling the front grille 20 is provided on the main body 1.

[0026] Among them, a sealing mechanism is provided on the main body 1 for sealing the interior of the main body 1.

[0027] As Figure 3-4 shown, an auxiliary mechanism is further included in this embodiment. The auxiliary mechanism includes limiting plates 12 installed on one side of the front grille 20 at equal intervals in a circular arrangement. The limiting plates 12 are arc-shaped. Limiting holes 11 are opened on the limiting plates 12. A limiting rod 17 is slidably installed on one side of the main body 1. One end of the limiting rod 17 is fixedly installed with a pulling plate 15. A spring 16 is fixedly installed on the main body 1. One end of the spring 16 is fixedly connected to the pulling plate 15. The other end of the limiting rod 17 is located in the limiting hole 11. When it is necessary to remove the front grille 20, pull the pulling plate 15 outwards. The pulling plate 15 drives the limiting rod 17 to move out of the limiting hole 11, canceling the fixation of the front grille 20. At this time, the front grille 20 can be taken out. When installing the front grille 20, pull the pulling plate 15 upwards, the spring 16 contracts, insert the limiting plate 12 into the main body 1. When the limiting hole 11 moves to the position of the limiting rod 17, the spring 16 rebounds to drive the limiting rod 17 to insert into the limiting hole 11 to fix the front grille 20, realizing the rapid cleaning of the interior of the main body 1 and convenient maintenance.

[0028] As Figure 1-2As shown in the figure, the present embodiment further includes a sealing mechanism. The sealing mechanism includes a mounting frame 2 rotatably installed at the bottom of the main body 1, enabling the main body 1 to vertically change its rotation angle. A telescopic rod 3 is fixedly installed at the bottom of the mounting frame 2, enabling the main body 1 to horizontally change its rotation angle. A connecting block 4 is fixedly installed at the bottom of the telescopic rod 3. A base 6 is hinged to the connecting block 4. A notch 5 is formed in the base 6. The main body 1 is located within the notch 5. A first connecting plate 13 is fixedly installed on one side of the main body 1. An installation frame 7 is fixedly installed on one side of the first connecting plate 13. A second connecting plate 8 is rotatably installed within the installation frame 7. A plurality of identical through holes 10 are formed in the first connecting plate 13 and the second connecting plate 8. The second connecting plate 8 is attached to and rotatably connected to the first connecting plate 13. When it is necessary to seal the main body 1, the telescopic rod 3 is retracted, the telescopic rod 3 is flipped, the main body 1 is flipped into the notch 5, the rotating block 9 is rotated, the rotating block 9 drives the second connecting plate 8 to rotate, so that the through holes 10 on the second connecting plate 8 are misaligned, and the area on the second connecting plate 8 without the through holes 10 moves to the position of the through holes 10 on the first connecting plate 13, thereby sealing the through holes 10. When using it again, just perform the reverse operation. This realizes the folding of the main body 1 and at the same time avoids dust falling inside the idle main body 1.

[0029] As Figure 3-4 As shown in the figure, a plurality of equally spaced limiting grooves 19 are formed on one side of the main body 1. The limiting plate 12 is located within the limiting grooves 19. A sliding groove 14 is formed in the installation frame 7. The second connecting plate 8 is located within the sliding groove 14. A rotating block 9 is fixedly installed on one side of the second connecting plate 8. Anti-slip blocks are provided on the rotating block 9.

[0030] Working principle: When it is necessary to remove the front mesh cover 20, the pull plate 15 is pulled outwards, and the pull plate 15 drives the limiting rod 17 to move out of the limiting hole 11, canceling the fixation of the front mesh cover 20. At this time, the front mesh cover 20 can be taken out. When installing the front mesh cover 20, the pull plate 15 is pulled upwards, the spring 16 contracts, and the limiting plate 12 is inserted into the main body 1. When the limiting hole 11 moves to the position of the limiting rod 17, the spring 16 rebounds and drives the limiting rod 17 to insert into the limiting hole 11 to fix the front mesh cover 20. When it is necessary to seal the main body 1, the telescopic rod 3 is retracted, the telescopic rod 3 is flipped, the main body 1 is flipped into the notch 5, the rotating block 9 is rotated, the rotating block 9 drives the second connecting plate 8 to rotate, so that the through holes 10 on the second connecting plate 8 are misaligned, and the area on the second connecting plate 8 without the through holes 10 moves to the position of the through holes 10 on the first connecting plate 13, thereby sealing the through holes 10. When using it again, just perform the reverse operation. This realizes the rapid cleaning and convenient maintenance of the interior of the main body, reduces the occupied space, and at the same time avoids dust falling inside the idle main body.
