Description

Technical Field

[0001] This utility model belongs to the technical field of fans, and relates to a ceiling fan with integrated lighting and low wind speed. Background Technology

[0002] A mini ceiling fan is a small ceiling fan mainly composed of a motor, fan blades, a hanging rod, and a speed controller. Its working principle is that the motor drives the fan blades to rotate, propelling airflow and creating a gentle breeze. Due to its gentle breeze, quiet operation, energy efficiency, and easy installation, a mini ceiling fan is ideal for use in small spaces such as bedrooms, living rooms, and offices, and is especially suitable for noise-sensitive environments. Through continuous rotation, a mini ceiling fan not only effectively cools the room but also improves air circulation, providing a comfortable indoor environment. In these applicable scenarios, lighting is generally required; therefore, adding lighting functionality to a mini ceiling fan is highly recommended.

[0003] Chinese utility model patent CN201184316Y (publication date: January 21, 2009) discloses an LED light fan, which consists of a clamp, a pole, an externally rotating rotor motor, a housing, and fan blades. A lampshade is located in front of the fan rotor, and inside the lampshade is an LED light source assembly fixed to the main frame by screws via a hollow rotating shaft. This LED light fan not only functions as a fan but also provides lighting functionality through its LED light source assembly.

[0004] When in use, the lamp cover of the aforementioned lamp fan will rotate simultaneously with the rotor, which will not only increase the load on the rotor rotation and reduce the stability of the rotor rotation, but also make it easy to be damaged. Utility Model Content

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-2 :

[0025] A ceiling fan with integrated lighting and low airflow, comprising:

[0026] Fan assembly 1 includes a motor shaft 3, an inner stator 4, an outer rotor 5, and fan blades 6. The inner stator 4 is rigidly connected to the motor shaft 3. The drive structure of the fan assembly 1 adopts a claw-pole permanent magnet synchronous motor. The inner stator 4 includes stator claw poles and stator windings. The outer rotor 5 includes an upper end cover, a lower end cover, and permanent magnet poles. The outer rotor 5 is rotatably connected to the motor shaft 3 through an upper bearing 7 and a lower bearing 8. Both the upper bearing 7 and the lower bearing 8 are ball bearings. The outer ring of the upper bearing 7 and the lower bearing 8 are interference-fitted with the outer rotor 5, and the inner ring is interference-fitted with the motor shaft 3. The fan assembly 1 is electrically connected to a power source and drives the fan blades 6 to rotate through the motor to provide heat dissipation.

[0027] The lamp assembly 2 includes a lamp holder 10, a lamp 11 fixed in the lamp holder 10, and a lamp cover 12 connected to the top of the lamp holder 10. The lamp 11 can be a common lamp 11 in the art. Preferably, the lamp 11 is an LED lamp, including a circuit board and lamp beads. The lamp assembly 2 is electrically connected to a power supply and is used to provide lighting function.

[0028] The suspension assembly includes a suspension pipe 9, which suspends the fan assembly 1 and the lamp assembly 2. Both the suspension pipe and the motor shaft 3 are hollow structures used to pass through the power cord that is electrically connected to the lamp assembly 2.

[0029] The aforementioned components are connected as a whole via a motor shaft 3. Specifically, the upper and lower ends of the motor shaft 3 pass through the outer rotor 5, with the upper end connected to the hanging pipe 9 and the lower end connected to the lamp assembly 2. Both the hanging pipe and the lamp holder 10 participate in the bearing installation structure, thereby significantly simplifying the structure of the ceiling fan. Specifically, the motor shaft 3 is provided with a shoulder structure for installing the upper bearing 7 and the lower bearing 8. The top of the inner cavity of the outer rotor 5 is provided with an upper bearing seat 13, and the bottom is provided with a lower bearing seat 14. The upper bearing 7 and the lower bearing 8 are respectively interference-fitted into the upper bearing seat 13 and the lower bearing seat 14. The hanging pipe 9 extends downward into the outer rotor 5 and presses against the inner ring of the upper bearing 7. The inner edge ring of the lamp holder 10 extends upward into the outer rotor 5 and presses against the inner ring of the lower bearing 8.

[0030] Upon startup, the stator windings of the inner stator 4 generate a rotating magnetic field, driving the outer rotor 5 to rotate and in turn causing the fan blades 6 to rotate. The outer rotor 5 and the outer rings of the upper bearing 7 and lower bearing 8 rotate synchronously; the inner rings of the upper bearing 7 and lower bearing 8, as well as the motor shaft 3, inner stator 4, lamp assembly 2, and hanging assembly remain stationary and do not interfere with the rotation of the fan blades 6.

[0031] Furthermore, in order to make the structure of the ceiling fan more compact, the lower bearing seat 14 protrudes from the bottom plane of the outer rotor 5, and the lamp holder 10 is provided with a central groove 15 in the middle that is adapted to the lower bearing seat 14 and is lower than its top plane. Through the structure of the protruding lower bearing seat 14 and the central groove 15, the axial space of the ceiling fan can be saved.

[0032] The lamp holder 10 has an upwardly extending upper convex ring 18 on its top outer side, and the outer rotor 5 has a downwardly extending lower convex ring 19 on its outer side. The lower convex ring 19 is located outside the upper convex ring 18 and its bottom extends beyond the top of the upper convex ring 18. The upper convex ring 18 and the lower convex ring 19 form a labyrinth-type sealing structure. Through the labyrinth-type sealing structure, the ceiling fan can have a better dustproof effect.

[0033] In this embodiment, the motor shaft 3 is fixedly connected to the lamp holder 10 and the hanging tube 9 by fasteners. Specifically, the lower end of the motor shaft 3 is provided with an external thread, and the lamp holder 10 is provided with a locking nut 16 that is screwed to the motor shaft 3 and locks the lamp assembly 2. The hanging tube 9 passes through the center hole of the outer rotor 5 and is fitted onto the motor shaft 3. The motor shaft 3 and the hanging tube 9 are fixedly connected by a pin. The hanging tube 9 is covered with a dust cover 17 that shields the center hole of the outer rotor 5.

[0034] To enhance heat dissipation, the lamp holder 10 on the outer side of the upper convex ring 18 is provided with several heat dissipation holes for the lamp assembly 2, and the upper end cover of the outer rotor 5 is provided with several heat dissipation holes for the fan assembly 1.

[0035] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
