[0022] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] Reference Figure 1 and Figure 4 , an embodiment of a novel fan structure with pluggable fan blades and a motor embedded in the utility model is proposed:

[0024] A novel fan structure 1 with a pluggable motor and fan blades includes a fan body 13, a stator, a rotor, a fixed connector 11, and a limit connector 12.

[0025] A connecting column is provided in the middle of the fixed connecting member 11, and a connecting column through hole 111 is provided in the middle of the connecting column. The stator is fixedly connected to the connecting column. A connecting column wire hole is provided on the side of the connecting column. A fan body through hole 1313 is provided in the middle of the fan body 13. The connecting column passes through the fan body through hole 1313 and is connected to the limiting connecting member 12 through the connecting column through hole 1313, thereby rotating the fan body 13 between the fixed connecting member 11 and the limiting connecting member 12. The rotor is fixedly connected to the inner side surface of the fan body 13, and a connecting column wire hole is provided on the side surface of the connecting column. The line passes through the connecting column wire hole and is connected to the stator. By energizing the stator to form a magnetic field, the rotor can be driven to rotate, thereby driving the fan body 13 to rotate.

[0026] In this embodiment, the fan is an oscillating fan, which can also be used in structures such as a ceiling fan or a hidden fan light in actual use.

[0027] The fan comprises a base 2, a transmission gear set 4, an output gear 3, an oscillating motor, a rotatable member 5, and a novel embedded fan structure 1 with a pluggable fan blade motor. The oscillating motor is mounted on top of the base 2, and the rotatable member 5 is rotatably connected to the base 2. The output shaft of the oscillating motor is connected to the output gear 3, and the transmission gear set 4 is gear-engaged with the output gear 3 and the rotatable member 5, respectively, so that the oscillating motor can drive the rotatable member 5 to rotate.

[0028] The top of the fixed connector 11 is fixedly connected to the bottom of the rotatable member 5, and the circuit of the base 2 passes through the rotatable member 5 and the connecting column in sequence and is connected to the stator. The fan body 13 includes an annular connector 131, an upper cover and fan blades 132. A connecting boss 1311 is provided on the outer side of the annular connector 131, and a boss connecting slot 1312 is provided on the connecting boss 1311. A fan blade connecting protrusion 1321 is provided on the fan blade 132. The boss connecting slot 1312 and the fan blade connecting protrusion 1321 cooperate to clamp the fan blade 132 on the connecting boss 1311. A connecting hole 1314 is provided on the annular connector 131 inside the connecting boss 1311. Two cantilever hooks 1322 are arranged opposite to each other at the end of the fan blade 132. The cantilever hooks 1322 cooperate with the connecting hole 1314 to connect the fan blade 132 and the connecting boss 1311 more tightly. A fixing hole 1315 is also provided on the inner side of the annular connector 131, and a fixing block is provided on the side of the upper cover. The fixing block and the fixing hole 1315 cooperate to connect the upper cover to the top of the annular connector 131. A through hole is provided in the middle of the upper cover for the connecting column to pass through.

[0029] A first connecting bearing is provided between the fixed connecting member 11 and the fan body 13, and a second connecting bearing is provided between the limiting connecting member 12 and the fan body 13. By providing the first connecting bearing and the second connecting bearing, the fan body 13 can rotate more smoothly.
