[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] See also Figure 1 , Figure 2 and Figure 4 A fan fairing in this embodiment includes a fan frame 1, and four circumferentially arranged limit grooves 2 are opened on the upper surface of the fan frame 1. A limit plate 3 is fixedly connected between the two inner side walls of each limit groove 2, and a plug rod 4 is inserted into the side wall of each limit plate 3. The end of each plug rod 4 away from the fan frame 1 is fixedly connected to a limit disk 16. The setting of the limit disk 16 can prevent the plug rod 4 from falling off.

[0033] At the same time, a spring 17 is fixedly connected to one side of each limit plate 3 close to the wind turbine frame 1, and the other end of each spring 17 is fixedly connected to the limit plate 3 close to it, and each spring 17 is sleeved with the plug rod 4 close to it. By setting the spring 17, the automatic reset of the inclined block 5 can be achieved. The outer surface of each plug rod 4 is chamfered, and by chamfering the outer surface of the plug rod 4, the rotation of the plug rod 4 during the movement can be effectively avoided.

[0034] In addition, an inclined block 5 is fixedly connected to one end of each insertion rod 4 close to the center of the wind frame 1, and the upper surface of each inclined block 5 is set as an inclined surface. By setting the upper surface of the inclined block 5 as an inclined surface, the outer ring 6 can be easily installed quickly.

[0035] See also Figure 1 , Figure 3 and Figure 5 An outer ring 6 is placed on the inner bottom wall of the four limit grooves 2, and two reinforcing ribs 7 are fixedly connected to the inner wall of the outer ring 6. Four blocking rings 8 are fixedly connected to the outer surfaces of the two reinforcing ribs 7 respectively, and a sleeve 9 is fixedly connected between the two reinforcing ribs 7. The outer surface of the sleeve 9 is rotatably connected to a cleaning ring 10 through a bearing. Two cleaning plates 11 are sleeved on the outer surfaces of the four blocking rings 8, and the two cleaning plates 11 are fixedly connected to the cleaning ring 10. The outer surface of the cleaning ring 10 is knurled. The knurling process on the outer surface of the cleaning ring 10 can prevent the user from slipping during the rotation process.

[0036] See also Figure 1 , Figure 3 and Figure 5A plurality of ventilation grooves 12 are provided on the upper surface of the sleeve 9, an aromatherapy tube 13 is threadedly connected to the upper surface of the sleeve 9, an aromatherapy cream 14 is clamped inside the aromatherapy tube 13, and a handle 15 is fixedly connected to the outer surface of the aromatherapy tube 13. The setting of the handle 15 facilitates the user to replace the aromatherapy cream 14. The upper surface of the handle 15 is provided with a plurality of notches 18 arranged in a circle. The setting of the notches 18 facilitates the user to rotate.

[0037] A fan fairing in the present embodiment enters the limiting groove 2 of the fan frame 1 by pressing the outer ring 6. After the upper surface of the inclined block 5 is squeezed, it can drive the insertion rod 4 to move in the direction away from the fan frame 1. When the outer ring 6 contacts the inner bottom wall of the limiting groove 2, the inclined block 5 can be reset under the reset of the spring 17, thereby achieving the purpose of quick installation of the outer ring 6. By pulling the limiting plate 16, the outer ring 6 can be released from the limit, achieving the effect of quick disassembly. By rotating the cleaning ring 10, the cleaning plate 11 can be driven to make a circular motion on the outer surface of the blocking ring 8, which can achieve the purpose of pushing impurities and collecting them together, making it convenient for users to clean the blocking ring 8. The aromatherapy cream 14 is set to cooperate with the fan to generate airflow, which can increase fragrance in the airflow, thereby quickly purifying the odor in the environment and improving the comfort of the user.

[0038] It should be noted that the aromatherapy cream 14 can be removed from the aromatherapy tube 13 and replaced.

[0039] The working principle of the above embodiment is as follows: the fan frame 1 is fixedly connected to the output end of the external fan, and is pressed and contacted with the inclined block 5 by the outer ring 6. The inclined block 5 is squeezed and drives the insertion rod 4 to move, and at the same time stretches the spring 17. When the outer ring 6 contacts the inner bottom wall of the limiting groove 2, the spring 17 loses pressure and resets, driving the inclined block 5 to reset, and blocking and limiting the outer ring 6, thereby completing the rapid installation of the outer ring 6. By pulling the limiting plate 16 to drive the insertion rod 4 and the inclined block 5 to move, the outer ring 6 can be released from the limit. By rotating the cleaning ring 10, the cleaning plate 11 can be driven to rotate, and the impurities attached to the surface of the blocking ring 8 can be pushed out, which is convenient for the user to centrally handle them.

[0040] In addition, when the external blower fan rotates, the air flow can be delivered to contact the aromatherapy cream 14, which is convenient for the volatilization of the fragrance and achieves the effect of quickly purifying the air. By turning the handle 15, the aromatherapy tube 13 can be disassembled to facilitate the replacement of the aromatherapy cream 14.
