[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] Example 1

[0045] See Figures 1 to 5 As shown, a concealed fan light with an adjustable air outlet includes a frustum-shaped fan base 1. A fan motor 2 and fan blades 3 are fixed to the top surface of the frustum-shaped fan base, and a central light source plate 4 and a circular lampshade 5 are fixed to the bottom surface of the frustum-shaped fan base. In this embodiment, the fan motor and fan blades are conventional structures in the prior art, and the entire length of the fan blades is less than or equal to the diameter of the large circular surface of the frustum-shaped fan base. The circular lampshade can be connected to the bottom surface of the frustum-shaped fan base by snap-fit ​​or screw-on method, which is a conventional connection method in the prior art and therefore not described in detail. In actual applications, the fan motor and central light source plate are connected to an external power supply, which is common technical knowledge.

[0046] In this embodiment, an annular lifting air guide platform 6 is also provided, and the inner wall of the annular lifting air guide platform is integrally formed with a trumpet-shaped protrusion 7.

That is, during the lifting process, the distance between the edge of the frustum-shaped fan seat and the inner wall of the trumpet-shaped protrusion changes. When the frustum-shaped fan seat descends, it gradually enters the large diameter end of the trumpet-shaped protrusion, and the air outlet width increases. When the frustum-shaped fan seat rises, it gradually enters the small diameter end of the trumpet-shaped protrusion, and the air outlet width decreases, thereby realizing the adjustment of the air outlet size. The height of the trumpet-shaped protrusion can be set as needed. In this embodiment, the height of the trumpet-shaped protrusion is slightly greater than the height of the frustum-shaped fan seat.

[0047] Furthermore, a lifting drive structure 8 is provided between the edge of the frustum-shaped fan base and the annular lifting air guide platform; a lifting clearance slot 9 is provided on the side wall of the horn-shaped convex cylinder; the frustum-shaped fan base is located inside the horn-shaped convex cylinder, and an annular air outlet 20 is provided between the edge of the frustum-shaped fan base and the inner wall of the horn-shaped convex cylinder; the lifting drive structure drives the frustum-shaped fan base to rise and fall, and changes the size of the annular air outlet.

During assembly, the motor bracket is fixed to the top surface of the annular lifting guide platform, the drive motor is fixed to the motor bracket, and the drive gear is fixed to the main shaft of the drive motor. The bottom end of the vertical rack is fixed to the outer wall of the frustum-shaped fan base, and the vertical rack passes through the lifting clearance slot and meshes with the drive gear. The rotation of the drive motor drives the drive gear to lift and lower on the vertical rack. The drive gear and the vertical rack can improve the smoothness and reliability of lifting. In practical applications, there can be one or two lifting drive structures, with the two arranged on the symmetrical edges of the annular lifting guide platform. Alternatively, there can be multiple structures.

[0049] In this embodiment, the bottom surface of the annular lifting air guide platform is provided with an annular light source groove 10; a first annular light source 11 and a first annular lampshade 12 are fixed inside the annular light source groove. Furthermore, an L-shaped slot 13 is provided on the outer wall of the first annular lampshade, and a snap-fit ​​protrusion is provided on the inner wall of the annular light source groove; during assembly, the snap-fit ​​protrusion enters from the vertical part of the L-shaped slot and rotates to engage with the horizontal part of the L-shaped slot for positioning. The combination of the first annular light source and the central light source enhances the lighting and decorative effect, and the above structure also improves the ease and effectiveness of installing the first annular lampshade.

The air inlet seat, in conjunction with the annular lifting air guide platform, can protect the fan motor and fan blades, ensuring heat dissipation performance while reducing dust accumulation on the fan blades, facilitating cleaning and maintenance, and also reducing fan motor noise, thus improving user comfort.

[0051] In this embodiment, an annular light groove 16 is provided on the upper part of the outer wall of the air inlet seat. A second annular light source 17 and a second annular lampshade 18, which illuminate upwards, are fixed within the annular light groove. The light from the second annular light source illuminates upwards through the second annular lampshade. This structure allows upward illumination, enhancing the decorative effect. Furthermore, a dustproof net 19 is provided on the top surface of the air inlet window of the air inlet seat, improving dustproof performance.

[0052] Furthermore, the top surface of the air inlet seat is connected to a mounting plate 14. It can be fixed to the ceiling with screws. The air inlet seat can be fixed to the mounting plate with screws or buckles. It is a conventional structure for ceiling lights or ceiling fans, and is simply applied, so it is not described in detail.
