Problems solved by technology

[0003] Therefore, another double-blade ceiling fan is provided on the market. The double-blade ceiling fan has a central shaft, a first fan-blade group, and a second fan-blade group. The central shaft has a plurality of through holes. A blade set is positioned in one of the through holes through a sleeve and a pin, and the second blade set is also positioned in the other through hole through a sleeve and a pin, so that the first blade set and The second fan blade group can be positioned on the central shaft, and a motor drives the first fan blade group and the second fan blade group to rotate simultaneously. Only by aligning and combining the barrel and the pin with the above-mentioned through hole can the first fan blade set and the second fan blade set be positioned on the central axis. In addition to the limited load capacity, the assembly work is also time-consuming and troublesome , In addition, due to the limitation of the setting of the single motor, the function of the double-blade ceiling fan lacks change

Abstract

The invention discloses a coaxial dual ceiling fan device, and aims to solve the problem that the assembly is complicated and time-consuming in the prior art. The coaxial dual ceiling fan device comprises a central shaft provided with an expanded section; a first ceiling fan set provided with a first stator and a first rotor, wherein the first rotor is rotatingly combined with the central shaft, and when the first ceiling fan set is provided with a first bearing set and a first blade, the first blade is combined with the first rotor; and a second ceiling fan set, which comprises a second stator and a second rotor, wherein the second stator is fixedly combined with the central shaft, the second rotor is rotatingly combined with the central shaft, the second ceiling fan set comprises a second bearing set and a second blade, the second blade is combined with the second rotor, and the first bearing set or the second bearing set is positioned in the expanded section.

Description

technical field [0001] The invention relates to a ceiling fan, in particular to a coaxial double ceiling fan with two ceiling fan groups. Background technique [0002] Most of the existing ceiling fans use a motor to drive the blades to rotate to drive the airflow. If you want to provide a larger air volume, you need to install a large ceiling fan instead. However, the blades of this large ceiling fan are relatively long. It is troublesome and takes up a large area of ​​space. [0003] Therefore, another double-blade ceiling fan is provided on the market. The double-blade ceiling fan has a central shaft, a first fan-blade group, and a second fan-blade group. The central shaft has a plurality of through holes. A blade set is positioned in one of the through holes through a sleeve and a pin, and the second blade set is also positioned in the other through hole through a sleeve and a pin, so that the first blade set and The second fan blade group can be positioned on the cent...
