[0021] First of all, it should be pointed out that in the different described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosure contained in the entire description can be transferred to the same parts with the same reference numerals or the same component names. Selected positional descriptions in the description, such as top, bottom, lateral, etc., also refer to the directly described and shown figures and are transferred to the new positions in the case of a change in position.

[0022] Embodiment: A low noise high speed fan, such as Figure 1-Figure 6 As shown, it includes a mounting frame 1, a high-speed fan 2, a fixing screw 3, a fixing ring 4, a connecting shaft 5, a sealing ring 6, a first sound-absorbing cotton 7, a connecting block 8, a magnet 9, a mounting ring 10, a second sound-absorbing cotton 11, a fixing block 12, a docking block 14, a connecting ring 15, a filter 16, a latch 17 and a pulling ring 18. A high-speed fan 2 is placed on the mounting frame 1. A plurality of fixing screws 3 are threadedly connected to the high-speed fan 2 for fixing the high-speed fan 2. The fixing screws 3 are threadedly matched with the mounting frame 1. A fixing ring 4 is connected to the right side of the mounting frame 1. A connecting shaft 5 is rotatably connected to the fixing ring 4. A sealing ring 6 is rotatably connected to the connecting shaft 5. The sealing ring 6 cooperates with the fixing ring 4. The sealing ring 6 is semi-arc shaped. The sealing ring 6 and the fixing ring 4 are both connected with the first sound-absorbing cotton 7. The first sound-absorbing cotton 7 absorbs noise. The sealing ring 6 and the bottom of the fixing ring 4 are connected front and back. Symmetrically connected are connecting blocks 8, a magnet 9 is installed in the connecting block 8, and the two magnets 9 are magnetically connected. The fixing ring 4 and the sealing ring 6 are both connected with mounting rings 10, and the inner wall of the mounting ring 10 is installed with a second sound-absorbing cotton 11 to absorb the noise of the high-speed fan 2 rotating. The fixing ring 4 and the sealing ring 6 are both connected with fixing blocks 12. The number of fixing blocks 12 is not less than two, and a fixing hole 13 is provided on the fixing block 12. A docking block 14 is placed on the fixing ring 4, and a fixing hole 13 is also provided on the docking block 14. A connecting ring 15 is connected between the two docking blocks 14, and a filter screen 16 is installed in the connecting ring 15 to protect the high-speed fan 2. The fixing hole 13 in the fixing block 12 and the fixing hole 13 in the docking block 14 are clamped with a pin 17 for fixing the connecting ring 15 and the filter screen 16, and the pin 17 is connected to a pulling ring 18.

[0023] When it is necessary to use the device, during the use of the high-speed fan 2, because the high-speed fan 2 makes too much noise when rotating, when it is necessary to reduce the noise of the high-speed fan 2, the user pulls the connecting block 8 to drive the sealing ring 6 to rotate clockwise to 180 degrees along the connecting shaft 5. When the sealing ring 6 rotates to a suitable position, the connecting block 8 is loosened. At this time, the magnet 9 on the connecting block 8 is out of contact with the magnet 9 on the other connecting block 8, and then the high-speed fan 2 is placed on the mounting frame 1. After the high-speed fan 2 is placed, the fixing bolt is placed on the high-speed fan 2, and the fixing bolt is turned to rotate along the high-speed fan 2. When the fixing bolt is rotated to a suitable position, it is convenient to install the high-speed fan 2 on the mounting frame 1. After completing the installation of the high-speed fan 2, the connecting block 8 is pulled again to drive the sealing ring 6 to rotate counterclockwise to 180 degrees, so that the sealing ring 6 fits with the fixing ring 4. At the same time, the two magnets 9 contact and attract each other. When in use, a relatively large noise will be generated. The first sound-absorbing cotton 7 can absorb the noise generated by the high-speed fan 2. If the sound generated by the high-speed fan 2 is louder, the second sound-absorbing cotton 11 can absorb the sound generated when the high-speed fan 2 rotates. When the high-speed fan 2 needs to be disassembled or repaired, repeat the above operation to open the sealing ring 6, and then remove the fixing screw 3, and the high-speed fan 2 can be directly removed, which is convenient for disassembly and repair of the high-speed fan 2. When the air outlet of the high-speed fan 2 needs to be protected, the user places the docking block 14 on the fixing block 12, and aligns it with the fixing hole 13, so that the connecting ring 15 is in contact with the front side of the fixing ring 4 and the sealing ring 6, and then the pin 17 is clamped in the fixing hole 13 on the fixing block 12 and the docking block 14 to complete the installation of the connecting ring 15 and the filter 16, and the front side of the high-speed fan 2 can be protected at the same time.

[0024] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
