[0030] It should be understood that when used in this specification and the appended claims, the terms "comprises" and "comprising" indicate the presence of the described features, wholes, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, wholes, steps, operations, elements, components, and / or their combinations.

[0031] It should also be understood that the terms used in the description of the embodiments of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the embodiments of the present utility model. As used in the description of the embodiments of the present utility model and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include the plural forms.

[0032] Please refer to Figure 1 , an embodiment of the present utility model provides a quickly detachable fan, which includes a fan head structure 1, a driving mechanism 2, a support rod 3 and a base 4. The fan head structure 1 is detachably connected to the driving mechanism 2, and the support rod 3 and the base 4. One end of the support rod 3 is connected to the driving mechanism 2, and the other end is connected to the base 4. The driving mechanism 2 is used to drive part of the fan head structure 1 to rotate to generate wind during operation. The base 4 is used to contact the ground, and the support rod 3 is used to raise the height of the fan head structure 1.

[0033] In the embodiment of the present utility model, it is preferred that the height of the support rod 3 is 0.9 - 1.2 m. In this way, the needs of users can be adapted within a relatively large range.

[0034] Please refer to Figure 2 , the fan head structure 1 of the present utility model includes a fan blade structure 5, a front net 6, a rear net 7, a bearing 8 and a net bundle (not shown in the figure). The fan blade structure 5 includes blades 10, a bearing part 11 and a connecting part 12. The blades 10 are connected to the periphery of the bearing part 11, and the connecting part 12 is connected to the middle position of the bearing part 11. The connecting part 12 has a cylindrical structure and its axial direction is perpendicular to the rotation plane of the blades 10. A circular through hole 13 matching the shape and size of the outer ring of the bearing 8 is provided at the middle position of the rear net 7. The bearing 8 is connected to the circular through hole 13 by interference fit of its outer ring. It can be understood that the rear net 7 can also be detachably connected by snapping the outer ring structure of the bearing 8. One end of the connecting part 12 passes through the inner ring of the bearing 8 and is in interference fit with its inner ring. It can be understood that the connecting part 12 can also be detachably connected to the inner ring structure of the bearing 8 by means of clamping, pressing, etc. The front net 6 and the rear net 7 are detachably connected. The fan blade structure 5 is located in the space enclosed by the front net 6 and the rear net 7. The connecting part 12 passing through the bearing 8 is detachably connected to the net bundle. In the present utility model, the connecting part 12 and the net bundle are connected by a threaded connection. The dimension of the bearing 8 in the radial direction is smaller than the dimension of the net bundle. The setting of the bearing 8 connects the fan blade structure 5 and the rear net 7. The interference fit design also provides some convenience for disassembly and installation. The dimension of the net bundle in the radial direction being larger than that of the bearing 8 helps to prevent the connecting part 12 from coming out and the rear net 7 from coming out backward from the bearing 8.

[0035] In the embodiment of the present utility model, preferably, the net bundle and the connecting part 12 are detachably connected by means of threaded connection, including but not limited to this, and it can also be achieved by means of interference fit, and specific design can be carried out according to the actual situation; preferably, the number of blades 10 is set to 2-16, which can meet the needs of most users for the number of blades 10, and it can also be set to 1 or more than 16.

[0036] Please refer to Figure 3 , further, in the axial direction of the connecting part 12, a placement connection hole 14 is opened at the free end of the connecting part 12. The shape and size of the output end of the driving mechanism 2 match the shape and size of the placement connection hole 14. The output end part of the driving mechanism 2 is connected into the placement connection hole 14 and is detachably connected to the connecting part 12. Specifically, the output end of the driving mechanism 2 and the placement connection hole 14 of the connecting part 12 are detachably connected by means of threaded connection or interference fit, which is convenient for the user to detach the fan head structure 1 from the driving mechanism 2 or install it on the driving mechanism 2, and is convenient for cleaning, maintenance and replacement of the fan head structure 1 and the driving mechanism 2. In practice, other methods can also be used to achieve detachable connection, which will not be elaborated here.

[0037] Please refer to Figure 3 , the driving mechanism 2 includes a housing 15 and a motor 16. The motor 16 is arranged in the housing 15, and the output end part of the motor 16 extends out of the housing 15. The housing 15 is detachably connected to the rear net 7. Specifically, a rotating buckle 17 is arranged on the housing 15 on the circumferential side where the output end of the motor 16 extends out of the housing 15, and a bayonet 18 is opened on the rear net 7 on the circumferential side of the circular through hole 13. The rotating buckle 17 and the bayonet 18 match each other. When the output end of the motor 16 is detachably connected to the placement connection hole 14 of the connecting part 12, the rotating buckle 17 is placed in the bayonet 18 and is clamped in the bayonet 18 under the action of a rotating external force, which increases the stability of the connection structure. The user can manually rotate and pull the rotating buckle 17 out of the bayonet 18 and pull out the output end of the motor 16 from the placement connection hole 14 to achieve separation.
