Abstract

The invention discloses a hidden fan blade ceiling fan lamp which comprises a rotary disc, a motor upper cover, belt wheels, fan blades and tension springs. The rotary disc is fixed to the upper surface of a bottom disc. A motor assembly is arranged in the motor upper cover and connected with the rotary disc. Fan fixing discs are arranged on the rotary disc. Each belt wheel is sleeved with the corresponding fan fixing disc. The four fan blades are fastened on the four fan fixing discs. A gear is arranged at the upper end of each fan fixing disc. One end of each of the four belt wheels is engaged with the corresponding gear, and the other ends of the four belt wheels are engaged with four small gears. The small gears are mounted at arc groove positions of a limiting plate and engaged with inner teeth at the arc groove positions. One end of each tension spring is connected with the rotary disc, and the other end of each tension spring is connected with the limiting plate. According to the hidden fan blade ceiling fan lamp, the fan blade opening angle ranges from 120 degrees to 150 degrees, and the optimal air volume and the effect of lowering noise can be achieved; and by means of a belt wheel transmission structure, too high noise generated by direct contact of sun gear combination planet gears is avoided.

Description

technical field [0001] The invention belongs to the technical field of ceiling fan lamps, and in particular relates to a ceiling fan lamp with invisible fan blades. Background technique [0002] 200680032396.1 invention patent discloses a combined lamp ceiling fan. [0003] 1) The combined ceiling fan and light fixture according to claim 12, wherein when the blades are in their storage positions, the part of each blade between its pivot axis and its tip end faces the The angle of the rotation axis of the fan is about 160 to 170 degrees. The improvement plan of this product is to use the fan blades with an opening angle of 120-150 degrees. This angle has been tested by this product to achieve the best air volume and reduce noise. [0004] 2) According to the content of the 200680032396.1 invention patent, according to the description in the specification, the structure uses the sun gear and the planetary gears arranged around its periphery to realize the principle of synchr...
