Problems solved by technology

[0002] Ceiling fan is a common electrical appliance for heatstroke prevention and cooling in summer. However, most ceiling fans now need to occupy a relatively large space due to the large blades and dust is easy to accumulate on the blades.
As people's requirements for cleanliness and beauty are getting higher and higher, household appliances that are clean and take up less space are becoming more and more popular, and foldable ceiling fans are inconvenient to install and disassemble.

Abstract

The invention discloses a ceiling fan with telescopic fan blades. The ceiling fan comprises a base, a swing pipe, a rotation disc, connection pieces, first fan blades and second fan blades. One end of the swing pipe is fixed on the base, and the other end of the swing pipe is fixedly provided with the rotation disc; the connection pieces connect the rotation disc and the first fan blades; the first fan blades are hollow structures, and guide grooves and limit grooves are formed in the first fan blades; the second fan blades are hollow structures, and guide blocks and limit blocks are arranged on the outer sides of the second fan blades; the second fan blades are arranged in the first fan blades and fixed on the first fan blades through springs. The ceiling fan is simple in structure, it is guaranteed that the second fan blades are accommodated in the first fan blades under the traction of the springs when the ceiling fan is not in a working state, occupied space is reduced, dust can not easily stain the second fan blades, in work, under the action of centrifugal force, the second fan blades extend out of the first fan blades, the area of the fan blades is increased, and the fanning effect is enhanced.

Description

technical field [0001] The invention relates to a daily life device, in particular to a ceiling fan with retractable fan blades. Background technique [0002] Ceiling fan is a common electrical appliance for heatstroke prevention and cooling in summer. However, most ceiling fans now need to occupy a relatively large space because of their large blades, and dust is easy to accumulate on the blades. As people's requirements for cleanliness and beauty are getting higher and higher, household appliances that are clean and take up little space are becoming more and more popular, and foldable ceiling fans are inconvenient to install and disassemble. For this reason, we provide a ceiling fan with retractable fan blades, which has retractable fan blades, is not easy to be stained with dust, and saves space. Contents of the invention [0003] In view of the above situation, the object of the present invention is to provide a ceiling fan with retractable fan blades. [0004] The p...
