[0025] like Figures 1 to 5 As shown, this embodiment provides an integrated fan bulb, including a mounting base 1, a fan body 2, and a light-emitting part 3. The mounting base 1 is provided with a central shaft 11, and a stator 12 is fixed on the central shaft 11. The fan body 2 has a first through hole 201 and a second through hole 202 at its axial center. The second through hole 202 is located in front of the first through hole 201, and the diameter of the second through hole 202 is smaller than the diameter of the first through hole 201. A rotor 13 is fixed in the first through hole 201. After being powered on, the rotor rotates around the stator. A bearing 21 is installed in the second through hole 202. The central shaft 11 passes through the rotor 13 and is fixedly connected to the bearing 21. The rotor 13 is located around the stator 12. The light-emitting part 3 is installed at the end of the central shaft 11. Several fan blades are provided around the fan body 2. The fan body 2 and the fan blades are integrally injection molded. Using integral injection molding can improve the stability of the fan blades, making them less prone to deformation and increasing their service life.

[0026] As an optional embodiment, a positioning shaft 14 is provided on the central shaft 11, the diameter of the positioning shaft 14 is larger than the diameter of the central shaft 11, the stator 12 is fixed on the positioning shaft 14, and the diameter of the positioning shaft 14 is determined by the diameter of the stator 12.

[0027] As an optional embodiment, a protrusion 141 and a groove 121 are provided between the stator 12 and the positioning shaft 14. The protrusion 141 is embedded in the groove 121, so that the stator 12 can be fixedly connected to the positioning shaft 14 and avoid rotation.

[0028] As an optional embodiment, the rear end of the fan body 2 is provided with an end cover 22. The fan body 2 and the end cover 22 are fixedly connected. The end cover 22 covers the stator 12 and the rotor 13. During the installation process, the stator 12 is fixed on the positioning shaft 14, and then the rotor 13 is fixed inside the fan body 2. The fan body 2 is placed on the stator 12, and then the end cover 22 is closed and fixed with screws. In this way, the fan body 2 will not fall off during use.

[0029] As an optional embodiment, the groove 141 is provided with a step 142, and the end cap 22 is located on the step 142.

[0030] As an alternative embodiment, the heat of the existing fan bulb is difficult to dissipate because it is installed inside the housing, which can easily cause the motor to overheat and damage it. To improve the fan bulb, a number of air guide vanes 23 are arranged around the first through hole 201. The air guide vanes 23 are arranged around the central axis. During operation, the air guide vanes 23 can draw air into the motor to reduce heat.

[0031] As an optional embodiment, the light-emitting part 3 includes a lampshade 31, a lamp holder 32, and an LED light source 33. The LED light source 33 is installed inside the lamp holder 32, the lampshade 31 covers the lamp holder 32, and the lamp holder 32 is fixedly connected to the end of the central shaft 11.

[0032] As an optional embodiment, the mounting base 1 is fitted with a housing 4, and a lamp holder is mounted on the housing 4.

[0033] The incoming power is divided into two parts: one part connects to the motor, that is, the stator 12, which generates a magnetic field to make the rotor 14 rotate; the other part connects to the LED light to emit light. Because the rotor 14 is fixed inside the fan body 2, the fan body 2 will rotate after being powered on.

[0034] The existing fan blades and rotating disk are detachably connected. In this structure, the blades are prone to detachment and deformation under the assistance of air during use, which affects the use of the fan. The fan body 2 is equipped with several fan blades on its periphery. The fan body 2 and the fan blades are integrally injection molded. Using integral injection molding can improve the stability of the fan blades, make them less prone to deformation, and extend their service life.

[0035] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited thereto. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model are equivalent substitutions and are included within the protection scope of the present utility model.
