Description

A hidden fan Technical Field

[0001] This application belongs to the field of fan technology, and more specifically, relates to a concealed fan. Background Technology

[0002] Concealed fans are an improvement on traditional fixed-wing ceiling fans. The blades of a concealed fan are usually set on the turntable of the ceiling fan by a rotating device. When the ceiling fan is started, the blades are thrown out by centrifugal force. When the fan stops, the blades automatically retract to achieve the effect of being invisible. However, most concealed fans at present use gear transmission, which is complex in structure. Long-term use can easily lead to gear loosening, which is not conducive to transmission. In addition, the overall weight increases, which increases the cost of manufacturing and transportation. Utility Model Content

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

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

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

[0006] An electric motor having a connecting shaft and a rotor, the rotor being sleeved on the connecting shaft;

[0007] A turntable connected to the rotor, the turntable having a through hole and a first positioning post;

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

[0009] A rotating ring, wherein a first sliding groove is provided along its circumference, a second sliding groove is provided along its radial direction, a guide post is inserted into the first sliding groove, and a second positioning post is provided on the rotating ring;

[0010] A connector, one end of which is provided with a slide rod inserted into the second slide groove, and the other end of which is provided with a rotating shaft inserted into the through hole;

[0011] Fan blades, the fan blades being connected to the rotating shaft;

[0012] A reset spring, one end of which is connected to the first positioning post, and the other end of which is connected to the second positioning post.

[0013] Preferably, it also includes a lamp body, which is connected to the connecting shaft.

[0014] Preferably, it also includes a lampshade, which is connected to the lamp body.

[0015] Preferably, it also includes a boom, which is connected to the connecting shaft.

[0016] Preferably, it also includes mounting accessories, which are connected to the boom.

[0017] Preferably, the fan blade is provided with a third positioning post, the other end of the return spring is not connected to the second positioning post, and the other end of the return spring is connected to the third positioning post.

[0018] Compared with existing technologies, the concealed fan of this application features a turntable, guide post, and rotating ring. By incorporating a first and second sliding groove on the rotating ring, the rotor drives the turntable to rotate, which in turn drives the guide post to rotate. The guide post, via the first sliding groove, drives the rotating ring to rotate, and the rotating ring, via the second sliding groove, drives the connecting piece to rotate. The connecting piece then drives the fan blades to rotate, and the fan blades unfold under centrifugal force. When the rotor stops, a return spring resets the rotating ring, thereby resetting the fan blades. The entire process is simple and quick, with a compact structure and light weight, reducing manufacturing and transportation costs. Attached Figure Description

[0027] It should be noted that, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. Similar reference numerals and letters denote similar items in the following figures; therefore, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0028] As shown in Figures 1-3, this embodiment provides a concealed fan, including a motor 1, a turntable 2, a guide post 3, a rotating ring 4, a connector 5, fan blades 6, and a return spring 7. The motor 1 has a connecting shaft 1a and a rotor 1b, with the rotor 1b sleeved on the connecting shaft 1a. The turntable 2 is connected to the rotor 1b, and the turntable 2 is provided with a through hole and a first positioning post 2a. The guide post 3 is installed on the turntable 2. The rotating ring 4 is provided with a first sliding groove 4a along its circumference. The ring 4 has a second groove 4b arranged radially therein, the guide post 3 is inserted into the first groove 4a, and the rotating ring 4 has a second positioning post 4c; one end of the connecting member 5 is provided with a sliding rod 5a, which is inserted into the second groove 4b, and the other end of the connecting member 5 is provided with a rotating shaft, which is inserted into the through hole; the fan blade 6 is connected to the rotating shaft; one end of the return spring 7 is connected to the first positioning post 2a, and the other end of the return spring 7 is connected to the second positioning post 4c.

[0029] In some preferred embodiments of this invention, a lamp body 8 is further included, which is connected to the connecting shaft 1a. Thus, the lamp body 8 can provide illumination, ensuring the fan's multi-functionality and meeting various needs.

[0030] In some preferred embodiments of this utility model, a lampshade is also included, which is connected to the lamp body 8.

[0031] In some preferred embodiments of this invention, a hanger rod 9 is further included, which is connected to the connecting shaft 1a. Thus, the hanger rod 9 facilitates fan installation.

[0032] In some preferred embodiments of this invention, a mounting accessory 10 is further included, which is connected to the suspension rod 9. Thus, the mounting accessory 10 facilitates fan installation.

[0033] In some preferred embodiments of this utility model, a microwave sensor is also included.

If there is, the fan and the light are turned on; if not, the fan and the light are turned off, making it more intelligent and energy-saving.

[0034] Because the return spring 7 acts on the rotating ring 4, the fan blade 6 retracts unevenly, resulting in a colliding sound, as shown in Figure 4. In this application, the fan blade 6 is equipped with a third positioning post 6a. The other end of the return spring 7 is not connected to the second positioning post 4c, but is connected to the third positioning post 6a. Thus, the return spring 7 acts directly on the fan blade 6, and the retraction torque decreases as the fan blade 6 retracts, and the retraction speed of the fan blade 6 also decreases until it returns to its original position.

[0035] It should be noted that a silicone ring is installed at the sliding rod, so that there is no noise during retrieval. The silicone ring acts as a damper for retrieval.

[0036] Compared with existing technologies, the concealed fan of this application features a turntable 2, guide post 3, and rotating ring 4. By providing a first groove 4a and a second groove 4b on the rotating ring 4, the rotor 1b drives the turntable 2 to rotate, the turntable 2 drives the guide post 3 to rotate, the guide post 3 drives the rotating ring 4 to rotate via the first groove 4a, the rotating ring 4 drives the connecting piece 5 to rotate via the second groove 4b, and the connecting piece 5 drives the fan blades 6 to rotate. The fan blades 6 unfold under the action of centrifugal force. When the rotor 1b stops, the return spring 7 drives the rotating ring 4 to reset, thereby resetting the fan blades 6. The entire process is simple and quick, with a compact structure and light weight, reducing manufacturing and transportation costs.
