Problems solved by technology

Since the traditional ceiling fan blades are fixed on the motor, the number and relative position of the blades cannot be changed.
Therefore, when a large number of fan blades are used, the motor of the ceiling fan is full of fan blades when viewed from the bottom up, and the entire ceiling fan looks cumbersome in structure and not beautiful enough.

Abstract

The invention aims to provide a ceiling fan with changeable fan blades so as to make the structure of the ceiling fan more attractive and reduce accumulated dust on the fan blades. The ceiling fan comprises a motor, a flange hanging head, a fixed blade fork cover and fixed fan blades. The ceiling fan is characterized in that the ceiling fan further comprises a movable blade fork cover and movable fan blades fixed to the movable blade fork cover; the movable blade fork cover and the fixed blade fork cover are arranged in the axial direction of the motor and rotationally connected with each other; the number of the fixed fan blades is equal to that of the movable fan blades, and the distribution angles of the fixed fan blades and the distribution angles of the movable fan blades are the same; the ceiling fan is provided with a limiting structure, so that the fixed fan blades and the movable fan blades are in a staggered state when the motor rotates; and the ceiling fan is further provided with a reset structure, so that the fixed fan blades and the movable fan blades are in an aligned state when the motor stops rotating. The ceiling fan with the changeable fan blades is provided with the fixed fan blades and the movable fan blades, and the ceiling fan is ingenious and compact in structure, convenient to mount, reliable in operation and excellent in practicability.

Description

technical field [0001] The invention belongs to the technical field of electric appliance manufacturing, and in particular relates to a ceiling fan with variable fan blades. . Background technique [0002] The number of fan blades is directly related to the air volume, the more blades, the greater the air volume. In order to obtain a larger air volume, some ceiling fans use four or even six blades. Because the blades of traditional ceiling fans are all fixed on the motor, the number and relative positions of the blades cannot be changed. Therefore, when a large number of fan blades are used, the motor of the ceiling fan is full of fan blades when viewed from the bottom up, and the whole ceiling fan seems to have a heavy structure and is not attractive enough. In addition, when not in use, the fan blades will be covered with dust, and the more fan blades, the more dust will accumulate on the fan blades. Therefore, after a long period of inactivity, once it is turned on, a...
