Description

Technical Field

[0001] The present application belongs to the field of fan technology, and specifically relates to a hidden fan. Background Art

[0002] Hidden fans are improvements based on traditional fixed-wing ceiling fans. The blades of a hidden fan are usually set on the turntable of the ceiling fan through a rotating device. When the ceiling fan starts, the blades are thrown out by centrifugal force. When it stops, the blades are automatically retracted to achieve an invisible effect. However, current hidden fans basically use gear transmission, which has a complex structure. Long-term use can easily cause gear loosening, which is not conducive to transmission. In addition, the overall weight increases, which increases the cost and transportation cost. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings in the prior art, the purpose of this application is to provide a hidden fan with a simple and compact structure, flexible and stable transmission, not easy to be damaged, light weight, and reduced construction and transportation costs.

[0004] The technical means adopted by this application to solve the above technical problems are:

[0005] This application provides a hidden fan, comprising:

[0006] A motor, the motor comprising a connecting shaft and a rotor, the rotor being sleeved on the connecting shaft;

[0007] A turntable connected to the rotor, the turntable being provided with a through hole and a first positioning column;

[0008] A guide post, the guide post being mounted on the turntable;

[0009] A swivel, wherein the swivel is provided with a first sliding groove along its circumferential direction, the swivel is provided with a second sliding groove along its radial direction, the guide post is inserted into the first sliding groove, and the swivel is provided with a second positioning post;

[0016] Preferably, it also includes a mounting accessory, which is connected to the suspension rod.

[0017] Compared to the prior art, the hidden fan of this application is equipped with a turntable, a guide post, and a rotating ring. By setting a first chute and a second chute on the rotating ring, the rotor drives the turntable to rotate, which in turn drives the guide post to rotate. The guide post drives the rotating ring via the first chute, and the rotating ring drives the connecting member via the second chute. The connecting member drives the fan blades to rotate, and the fan blades unfold under the action of centrifugal force. When the rotor stops, the return spring drives the turntable to reset, thereby resetting the fan blades. The entire process is simple and fast, with a compact structure and light weight, reducing construction and transportation costs. BRIEF DESCRIPTION OF THE DRAWINGS
