The plug-in part 22 includes a first plug plate 221 and a second plug plate 222 connected to the first plug plate 221 and forming an angle with it. The hub 1 includes several slots 11 disposed on its outer side and inserted into the first plug plate 221, and several slots 12 disposed on its upper side and engaged with the second plug plate 222. The upper end of the outer wall of the slot 11 is provided with a notch 13. The lower side of the blade 2 abuts against the bottom surface of the notch 13. A cover 3 is connected to the hub 1 to press the blades 2 onto the hub 1. This allows for a detachable connection between the blade 2 and the hub 1, enabling the blade 2 and hub 1 to be separated for easy packaging and transportation. Furthermore, when assembling the blade 2 onto the hub 1, the design of the notch 13 allows the blade 2 to slide onto the hub 1 without requiring complete alignment with the slot 11, making assembly simpler and faster. Simultaneously, the cover 3 is fixed to the output end of the motor shaft via a threaded connection. The motor shaft abuts against the hub 1 and passes through the hub 1 to connect with the cover 3, thereby pressing the blade 2 firmly onto the hub 1 for fixation.

[0028] In this design, a first positioning mechanism 4 is provided between the first insert plate 221 and the slot 11 to connect and fix the two together, and a second positioning mechanism 5 is provided between the second insert plate 222 and the slot 12 to connect and fix the two together. Specifically, the first positioning mechanism 4 includes a first positioning protrusion 41 disposed on the inner sidewall of the slot 11 and a first positioning hole 42 disposed on the first insert plate 221 and capable of engaging with the first positioning protrusion 41; the second positioning mechanism 5 includes a second positioning protrusion 51 disposed on the upper surface of the slot 12 and a second positioning hole 52 disposed on the second insert plate 222 and capable of engaging with the second positioning protrusion 51. Thus, through the first positioning mechanism 4 and the second positioning mechanism 5, a secure connection can be achieved without the use of tools; furthermore, even if the connection of the first positioning mechanism 4 or the second positioning mechanism 5 becomes loose, the blades 2 will not fly off, thereby ensuring that the fan blades will not loosen or fall off during high-speed rotation, providing a high level of safety.

[0029] In this design, the first positioning protrusion 41 is disposed on the bottom wall of the slot 11, and the upper side of the first positioning protrusion 41 is an inclined surface. A groove 111 is provided on the outer wall of the slot 11 at a position corresponding to the location of the first positioning protrusion 41, thereby facilitating the connection and fixation of the first positioning protrusion 41 with the first positioning hole 42. The second positioning protrusion 51 is disposed on the end of the slot 12 near the inner side of the hub 1, thereby improving the reliability of the fixed connection between the second positioning protrusion 51 and the second positioning hole 52.

[0030] In this design, a first recessed area 14 is provided on the upper surface of the hub 1, and a second recessed area 2221 is provided on the upper surface of the second insert plate 222. The first recessed area 14 and the second recessed area 2221 combine to form a recessed area that matches the bottom contour of the cover 3. Through the design of the first recessed area 14 and the second recessed area 2221, the cover 3 can be accurately installed within the recessed area, ensuring a tight fit between the cover 3, the hub 1, and the blade 2.

[0031] In this design, the included angle between the first insert plate 221 and the second insert plate 222 is 90 degrees. This design makes the connection between the first insert plate 221 and the second insert plate 222 and the slots 11 and 12 on the hub 1 more reliable. Meanwhile, the first insert plate 221 is arc-shaped, and its thickness gradually decreases from top to bottom. The second insert plate 222 is trapezoidal in shape, which facilitates the connection between the blade 2 and the hub 1 and reduces insertion resistance.

[0032] In this design, the bottom surface of the notch 13 is arc-shaped, and the shape of the lower side of the blade 2 matches the shape of the bottom surface of the notch 13. The lower side of the blade 2 abuts against the bottom surface of the notch 13 to provide installation and positioning, and also to make the fan blade look more aesthetically pleasing.

[0033] In this design, limiting grooves 112 are provided on both the left and right side walls of the slot 11, and limiting protrusions 2211 that can be inserted into the limiting grooves 112 are provided on both the left and right sides of the first insert plate 221, thereby making the connection between the blade 2 and the hub 1 more reliable. At the same time, the bottom of the slot 11 is provided with an abutment top 113 that can abut against the bottom surface of the first insert plate 221, which can be used to position the assembly of the blade 2 and the hub 1, and prevent the blade 2 from being damaged due to the installation height.

The fan includes fan blades as described above and a drive motor 7 mounted inside the ceiling box 6 to drive the fan blades to rotate. Several lamp arms 8 are detachably mounted on the ceiling box 6. The extended ends of the lamp arms 8 are provided with arc-shaped lamp holders 9, and the first and last ends of two adjacent lamp holders 9 are provided with fasteners 10 that allow them to connect. In this way, the lamp arms 8 and fan blades can be divided into several pieces during packaging and transportation, thereby reducing the space occupied and facilitating packaging and transportation. Furthermore, during transportation, each component can be packaged for protection to avoid damage.

[0035] In this design, the outer wall of the ceiling box 6 is provided with a U-shaped connector 61, and the lamp arm 8 is provided with a connector groove 81 that mates with the connector 61. The end of the lamp arm 8 connected to the ceiling box 6 is provided with a second protrusion 82, and the second protrusion 82 is provided with a first threaded hole 821. The ceiling box 6 is provided with a second threaded hole 62 that matches the first threaded hole 821. This allows the lamp arm 8 to be quickly snapped into the ceiling box 6 and then fixed by a threaded connection, eliminating the need for positioning the lamp arm 8 during assembly.

[0036] In summary, the installation steps for the fan light are as follows:

[0037] 1. Assembling the fan blades: Push the first insert plate 221 into the slot 11 to the bottom. At this time, the first positioning protrusion 41 on the bottom wall of the slot 11 will engage with the first positioning hole 42 of the first insert plate 221, accompanied by a "click" sound to confirm locking. At the same time, the second insert plate 222 of the blade 2 automatically falls into the slot 12 on the upper side of the hub 1, and the second positioning protrusion 51 on the inner end of the slot 12 engages with the second positioning hole 52 of the second insert plate 222, completing double locking.

[0038] 2. Install the lamp arm 8 and lamp holder 9 onto the ceiling box 6: Align the insertion slot 81 on the lamp arm 8 with the insertion connector 61 on the ceiling box 6 and insert it. Then, fix the two together by passing a screw through the first threaded hole 821 and locking it into the second threaded hole 62. Then, use the fastener 10 to splice the two adjacent lamp holders 9. Finally, install the light strip and light ring on the lamp holder 9.
