Description

Technical Field

[0001] This utility model relates to ceiling fans, and in particular to an improvement in the structure of a ceiling fan. Background Technology

[0002] Traditional ceiling fans are fixed to the ceiling with a suspension rod or a ceiling cover. A motor and multiple blades are installed below the suspension rod or ceiling cover. These blades rotate synchronously under the drive of the motor, thereby generating airflow and promoting air circulation.

[0003] However, regardless of whether it is a suspended or ceiling-mounted ceiling fan, the motor and blades of the ceiling fan are assembled as a single unit under the suspension rod or ceiling cover. Therefore, not only does the suspension rod or ceiling cover have to bear a large weight, but because the overall center of gravity is at the bottom, the ceiling fan is prone to large swings when it rotates. In addition, because the traditional motor and blades are too large, they not only create a visually oppressive feeling, but the blades are also limited in their shape design due to the space occupied by the motor, which is a pity.

[0004] In view of this, the inventor's long-term experience in research and development in related technical fields led to the creation of this utility model. Utility Model Content

[0005] The purpose of this utility model is to provide an improved structure for ceiling fans, which can not only raise the overall center of gravity of the ceiling fan, thereby reducing the disadvantage of ceiling fan swaying, but also make its appearance design more possible, thereby improving the overall aesthetics.

[0006] To achieve the above objectives, the improved ceiling fan structure provided by this utility model includes: a ceiling cover for fixing to the ceiling, with a through hole at the bottom of the ceiling cover; a motor fixed inside the ceiling cover, with a stator at its center and a rotor around the stator; a transmission unit, the upper end of which is fixed to the rotor of the motor, and the lower end of which passes through the through hole of the ceiling cover and extends downward to the bottom of the ceiling cover, and can rotate synchronously with the rotor of the motor; and a blade unit fixed below the transmission unit, and can rotate synchronously with the transmission unit.

[0007] Furthermore, the ceiling cover further includes a mounting base, a hanging plate, and a cover body. The mounting base is used to fix it to the ceiling, the hanging plate is located below the mounting base and is used to fix the stator of the motor, and the cover body covers the outside of the mounting base, the hanging plate, and the motor. The perforation is located at the bottom of the cover body.

[0008] Furthermore, the transmission unit further includes a transmission rod with a locking disc at its upper end for locking to the rotor of the motor, and the lower end of the transmission rod is locked to the blade unit. Additionally, a cover plate is fitted onto the transmission rod and locked to the blade unit. Furthermore, an auxiliary rod is provided on each side of the cover plate.

[0009] Furthermore, the blade unit is composed of multiple blades.

[0010] Therefore, by placing the motor inside the ceiling cover and transmitting torque directly to the lower blades via shaft drive, the overall center of gravity of the ceiling fan can be shifted upward, thereby reducing the disadvantage of ceiling fan oscillation. In addition, since the blades are no longer limited by the space occupied by the motor, there are more possibilities for its shape design, which can improve the overall aesthetics.

[0032] Please see Figure 1-3 As shown, it discloses an improved ceiling fan structure, comprising:

[0033] A ceiling cover 10 further includes a fixing base 11, a hanging dish 12 and a cover body 13, wherein the fixing base 11 is used to lock to the ceiling, the hanging dish 12 is located below the fixing base 11, and the cover body 13 covers the outside of the fixing base 11 and the hanging dish 12, and a through hole 131 is provided at the bottom of the cover body 13.

[0034] A motor 20 is located inside the housing 13, with a stator 21 at its center and fixed to the hanging plate 12, and a rotor 22 on the outer periphery of the stator 21.

[0035] A transmission unit 30 includes a transmission rod 31. The upper end of the transmission rod 31 is provided with a locking plate 32, which is locked below the rotor 22 of the motor 20 and can rotate synchronously with the rotor 22 of the motor 20. The lower end of the transmission rod 31 passes through the through hole 131 of the cover 13 and extends downward to the outside of the cover 13. The transmission unit 30 is fitted with a cover plate 33 on the transmission rod 31. An auxiliary rod 34 is provided on each side of the cover plate 33 to improve the strength of the transmission rod 31.

[0036] A blade unit 40 is composed of multiple blades 41. The blade unit 40 is locked to the lower end of the transmission rod 31 and the cover plate 33, and can rotate synchronously with the transmission unit 30. In addition to its covering function, the cover plate 33 also improves the horizontal stability of the blades 41.

[0037] To further understand the structural features, technical means, and expected effects of this utility model, the assembly method of this utility model will be described below, which will provide a deeper and more specific understanding of this utility model.

[0038] When assembling this utility model, first, lock the fixing base 11 to the ceiling, then install the hanging plate 12 below the fixing base 11, then lock the transmission rod 31 below the rotor 22 of the motor 20, then cover the outside of the motor 20 with the cover 13, and let the lower end of the transmission rod 31 pass out through the through hole 131 of the cover 13, then fix the stator 21 of the motor to the hanging plate 12. At this time, the assembly and fixing of the ceiling cover 10, the motor 20 and the transmission unit 30 to the ceiling are completed. Finally, put the cover plate 33 on the transmission rod 31, lock the blade unit 40 on the transmission rod 31, and finally lock the cover plate 33 on the blade unit 40. In this way, the overall assembly of the ceiling fan is completed.

[0039] Because this invention places the motor inside the ceiling cover and transmits torque directly to the lower blades via shaft drive, it not only raises the overall center of gravity of the ceiling fan, thereby reducing the swaying problem, but also allows for more design possibilities for the blades since they are no longer limited by the space occupied by the motor, thus improving the overall aesthetics and effectiveness.

[0040] However, the above description is only a preferred embodiment of the present utility model. Therefore, any equivalent structural changes made in accordance with the description and claims of the present utility model should be included within the patent scope of the present utility model.
