[0021] The technical solutions of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are some of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application.

[0022] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as there is no conflict.

[0023] Reference Figures 1-6 In one embodiment, a fan 100 (e.g. a ceiling fan) includes a body 10, a plurality of blades 20 connected to the body, and a plurality of connecting assemblies 30 disposed inside the body 10. Each connecting assembly 30 is connected to a corresponding blade 20, wherein each connecting assembly 30 includes a base 31 and an elastic member 32 connected to the base 31, the elastic member 32 including a column 321, each blade 20 includes a through hole 21, and the column 321 of the elastic member 32 of each connecting assembly 30 is received in the through hole 21 of the corresponding blade 20 to limit the movement of the blade 20 relative to the base 31.

[0024] With the above configuration, when connecting the blades to the body 10 of the fan 100, the quick pre-positioning of the blades 20 can be achieved through the cooperation of the through holes 21 of the blades 20 and the columns 321 of the elastic members 32 of the connecting assemblies 30, which is beneficial for the subsequent fixation of the blades 20 to the body 10 by screws.

[0025] In one embodiment, the body 10 is generally hollow and has a flat cylindrical shape, including a bottom plate 11 and a side wall 12 protruding from the bottom plate. A motor 13 is fixed on the outer surface of the bottom plate 11. The fan 100 further includes a first protective cover 40 covering the motor 13, a suspension rod assembly 50 connected to the ceiling, a connecting assembly 60 connecting the suspension rod assembly 50 and the motor shaft of the motor 13, and a second protective cover 70 covering the connecting assembly 60.

[0026] In one embodiment, the side wall 12 of the body 10 is provided with a plurality of elongated through holes 121, and the first end portions 22 of the plurality of blades 20 are respectively connected to the plurality of connecting assemblies 30 by passing through the plurality of through holes 121 on the side wall 12.

[0027] In one embodiment, each connecting assembly 30 is arranged in the space formed by the bottom plate 11 and the side wall 12 protruding from the bottom plate. Specifically, the base 31 of each connecting assembly 30 is fixed to the inner surface of the bottom plate 11, the front surface of the base 31 protruding two guide walls 33 spaced apart from each other, and the first end 22 of each fan blade 20 is received between the two guide walls 33 of the base 31 of the corresponding connecting assembly 30. One opening end of the space formed by the two guide walls 33 and the bottom plate 11 is opposite to a corresponding through hole 121, so that after the user inserts the first end 22 of a fan blade 20 into a corresponding through hole 121, the user can enter the above-mentioned opening end, and the continuous movement of the first end 22 will be guided by the guide walls 33, thereby facilitating the movement of the first end 22 of the fan blade 20 to the accurate position.

[0028] In one embodiment, the top ends of the two guide walls 33 include top plates 34 extending towards each other, and the first end 22 of each fan blade 20 is clamped between the front surface of the corresponding base 31 and the two top plates 34. Through such a structure, the two guide walls 33 limit the movement of the first end 22 of the fan blade 20 in the first direction, the two top plates 34 limit the movement of the first end 22 in the second direction, and the cooperation of the through hole 21 of the fan blade 20 and the column 321 of the elastic member 32 can limit the movement of the first end 22 in the third direction. Therefore, the fan blade 20 cannot move relative to the main body 10.

[0029] In one embodiment, the base 31 is fixed to the bottom plate 11 by a connecting portion 35, and the fixed portion 34 is connected to one end of the base 31. Referring to Figure 3 , the connecting portion 35 includes a portion extending in the vertical direction, so that the base 31 is separated from the bottom plate 11. In one embodiment, the elastic member 32 is located between the base 31 and the bottom plate 11, the elastic member 32 includes a body 322 fixed to the base 31 and an elastic arm 323 connected to the body 322, and the column 321 is connected to the end (i.e. free end) of the elastic arm 323. Referring to Figure 5 , the elastic arm 323 is a cantilever structure, and when the elastic arm 323 (especially near the position of the free end) is subjected to an external force perpendicular to the front surface of the base 31, the elastic arm 323 deflects, so that the column 321 of the elastic member 32 can move in the direction perpendicular to the front surface of the base 31.

[0030] It can be understood that the structure of the elastic member 32 is not limited thereto, and other suitable structures can be adopted as needed, for example, it can include a column and a cylindrical coil spring connected to the column.

[0031] In one embodiment, the base 31 is provided with a through hole 311, and the elastic member 32 is connected to the back side of the base 31 opposite to the front side, and the column 321 of the elastic member 32 penetrates through the through hole 311 of the base 31 and protrudes from the front side of the base 31. With such a structure, when the first end 22 is guided by the guide wall 33 to move inward, it will eventually contact the column 321 protruding from the front side of the base 31. In this embodiment, the top of the column 321 is spherical, and the front end of the first end 22 is chamfered. With such a structure, when the first end 22 contacts the column 321 protruding from the front side of the base 31, further pushing the fan blade 20 will cause the column 321 to be pressed perpendicularly to the front side of the base 31, so that the column 321 is pressed into the through hole 311 until the through hole 21 of the fan blade 20 is aligned with the through hole 311, at which time the column 321 is no longer pressed and rebounds, so that the column 321 is inserted into the through hole 21 of the fan blade 20, thereby achieving the pre-positioning of the fan blade 20.

[0032] In one embodiment, the base 31 includes a threaded hole 312, and correspondingly, the fan blade 20 is also provided with a through hole 23 on the first end 22. After the fan blade 20 is pre-positioned, the threaded hole 312 of the base 31 and the through hole 23 of the fan blade 20 are aligned. At this time, the user can pass a screw through the through hole 23 of the fan blade 20, and then use a tool to screw the screw into the threaded hole 312, thereby firmly fixing the fan blade 20 to the base 31.

[0033] In one embodiment, the front side of the base 31 protruding away from the bottom plate 11 has a blocking portion 35, and the first end 22 of the fan blade 20 is provided with an open slot 24, and the blocking portion 35 abuts against the closed end of the corresponding open slot 24 of the fan blade 20. With such a structure, after the fan blade 20 is pre-positioned, if the user continues to apply a pushing force to the fan blade 20, the fan blade 20 will be blocked by the blocking portion 35 and cannot continue to move inward due to the abutment of the blocking portion 35 against the closed end of the open slot 24. In this way, it is possible to avoid the fan blade 20 from continuing to move inward after being pre-positioned due to excessive force, resulting in the threaded hole 312 of the base 31 and the through hole 23 of the fan blade 20 no longer being aligned, and then the user cannot firmly fix the fan blade 20 to the base 31 by means of a screw.

[0034] In one embodiment, the fan 100 further includes a lighting assembly 80 connected to the main body. At this time, the fan 100 can also provide a lighting function, making it actually a fan lamp.

[0035] Through the above description, the use of the new type provides a structure for realizing the quick pre-positioning of the fan leaf. After the fan leaf realizes the pre-positioning, the through hole on the fan leaf and the threaded hole on the base are aligned, thereby allowing the user to conveniently screw the screw into the threaded hole. The above structure is simple and can realize the quick installation of the fan leaf.

[0036] Obviously, the above embodiments are only examples for clearly illustrating, but not limitation of the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments need not and cannot be exhausted. The obvious changes or variations derived therefrom are still within the protection scope of the utility model.
