Description

[Technical field]

[0001] The invention relates to the field of household appliances, and in particular to a ceiling fan lamp. [Background technology]

[0002] The ceiling fan lamp is a combination of a lamp and an electric fan. It has both the decorativeness of a lamp and the practicality of a fan. With the development of the economy, people's requirements for the quality of life are getting higher and higher, and ceiling fan lamps are beginning to be used by more and more people.

[0003] At present, the typical ceiling fan lamp on the market is a ceiling fan lamp with hidden blades. CN 101258366 B discloses a combined ceiling fan and lamp. The multiple blades of this ceiling fan lamp are retractable. When folded, the blades are all folded on the upper surface of the turntable. The folded blades have overlapping parts. The overlapping parts must be avoided when the blades are folded. Therefore, they must be processed into blades with a certain angle, which is complicated to process. In addition, in order to facilitate the folding of the blades, CN 102165252 B has improved the angle of the blades on the basis of CN 101258366 B, and provided a variety of blades, but did not completely solve the problem of small folding space for the blades and complex processing. In order to improve this problem, this solution adopts the method of 2 blades on the upper and lower surfaces. While ensuring the rotation stability of the turntable, it also provides a larger blade avoidance space, so that the blades can be made into straight blades, making the processing and production of the blades simpler and saving costs. In addition, both CN 101258366 B and CN 102165252 B use planetary gear transmission to adjust the extension and retraction of the fan blades, which results in poor synchronization when the fan blades are extended and retracted, affecting the appearance and performance of the ceiling fan lamp. Therefore, the present solution also improves the transmission mechanism for the extension and retraction of the fan blades, and uses a belt synchronous wheel to control the extension and retraction of the fan blades, which has a better synchronization. [Summary of the invention]

When folding, the motor 2 stops working, and the blades 5 are folded by the reset spring 8. The synchronization of the retraction and extension of each blade 5 is good, so that the ceiling fan lamp is more beautiful when unfolding and folding.

[0023] One of the preferred embodiments of the present invention is that the number of fan blades on the upper surface 31 and the lower surface 32 of the turntable 3 are both 2, and they are centrally symmetrical, with the centers of symmetry being the centers of the upper and lower surfaces of the turntable, respectively. The angles of the fan blades on the upper surface and the fan blades on the lower surface are 90°, and the shape of the fan blades themselves can be straight or inclined at a certain angle, so that the ceiling fan lamp runs more smoothly and reduces vibration when rotating.

The tooth portion 1 61 and the tooth portion 2 71 are engaged with each other to control the synchronous extension of the fan blades 5. The reset spring 8 retracts the fan blades 5 and returns them to their original positions when the turntable 3 does not rotate. The transmission is transmitted through the engagement of the teeth of the gears and the belt 7, and the transmission has high precision, making the extension and contraction of the fan blades 5 more beautiful.
