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.

[0032] Example

[0033] See Figures 1 to 4 As shown, a concealed fan light with screw-driven height adjustment 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.

[0034] In this embodiment, it is also provided with an annular lifting air guide platform 6, a mounting base 7, a control motor 8, a transmission screw 9, and a slider body 10; the inner wall of the annular lifting air guide platform is integrally formed with a horn-shaped protrusion 11, and the side wall of the horn-shaped protrusion is provided with a lifting avoidance slot 12; the lifting avoidance slot is mainly used for the lifting action of the lifting drive structure to ensure the effectiveness and smoothness of the lifting.

[0035] Meanwhile, the frustum-shaped fan base is located inside the horn-shaped protrusion, and an annular air outlet 13 is provided between the edge of the frustum-shaped fan base and the inner wall of the horn-shaped protrusion; the large-end diameter of the frustum-shaped fan base is smaller than the small-end inner diameter of the horn-shaped protrusion. That is, during the lifting and lowering process, the distance between the edge of the frustum-shaped fan base and the inner wall of the horn-shaped protrusion changes. When the frustum-shaped fan base descends, it gradually enters the large-diameter end of the horn-shaped protrusion, and the air outlet width increases. When the frustum-shaped fan base rises, it gradually enters the small-diameter end of the horn-shaped protrusion, and the air outlet width decreases, thereby achieving adjustment of the air outlet size. The height of the horn-shaped protrusion can be set as needed. In this embodiment, the height of the horn-shaped protrusion is slightly greater than the height of the frustum-shaped fan base.

[0036] During assembly, the mounting base is fixed to the annular lifting guide platform, the control motor is fixed to the mounting base, and the transmission screw is fixed to the main shaft of the control motor and passes vertically downward through the lifting clearance slot. The slider is fixed to the frustum-shaped fan seat and threadedly connected to the transmission screw. The control motor drives the frustum-shaped fan seat to rise and fall via the transmission screw. The lifting adjustment is achieved through the transmission screw and the threaded slider, improving the stability and effectiveness of the lifting adjustment. In this embodiment, the mounting base, control motor, transmission screw, and slider can be in two sets, located at opposite ends of the diameter of the annular lifting guide platform, ensuring the stability and reliability of the lifting. In practical applications, it can also be in one or more sets.

[0037] In this embodiment, the bottom surface of the annular lifting air guide platform is provided with an annular light source groove 14; a first annular light source 22 and a first annular lampshade 23 are fixed inside the annular light source groove. An L-shaped slot 15 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; 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. 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; moreover, the above structure also improves the ease and effectiveness of installing the first annular lampshade.

[0038] In this embodiment, an air inlet seat 16 is provided above the frustum-shaped fan base, and an air inlet window is provided on the top surface of the air inlet seat; the edge of the air inlet seat is fixed to the top surface of the annular lifting air guide platform by screws. 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.

[0039] Furthermore, in practical applications, an annular light groove 17 is provided on the upper part of the outer wall of the air inlet seat. A second annular light source 18 and a second annular lampshade 19, which emit upward-facing light, are fixed within the annular light groove. The light from the second annular light source shines upward through the second annular lampshade. This structure allows for upward illumination, enhancing the decorative effect.

[0040] The top surface of the air inlet window of the air inlet seat is equipped with a dustproof net 20, which can improve the dustproof performance.

[0041] The top surface of the air inlet base is connected to a mounting plate 21. It can be fixed to the ceiling with screws. The air inlet base can be fixed to the mounting plate with screws or buckles. It is a conventional structure for ceiling lights or ceiling fans, and is only used in a simple way, so it is not described in detail.

[0042] This utility model has the following positive effects: The structure of this utility model is reasonably designed, and it includes an annular lifting air guide platform, a mounting base, a control motor, a transmission screw, and a slider. Simultaneously, an annular air outlet is provided between the edge of the frustum-shaped fan base and the inner wall of the horn-shaped convex cylinder. The control motor, transmission screw, and slider work together to achieve lifting control of the frustum-shaped fan base. The size of the air outlet can be adjusted by the frustum-shaped fan base moving up and down within the horn-shaped convex cylinder. The adjustment operation is convenient, improving the overall aesthetics and facilitating cleaning and maintenance. It can meet the blowing needs of different air volumes, expanding its applicability. Furthermore, the overall structure has good heat dissipation performance and strong applicability.

[0043] An air inlet seat is set above the frustum-shaped fan base, and an air inlet window is set on the top surface of the air inlet seat. The air inlet seat, together with the ring lifting air guide platform, can protect the fan motor and fan blades, achieve the effect of an invisible fan, prevent the fan blades from getting dusty, and also improve the overall appearance. At the same time, it can also reduce the noise of the fan motor and improve the comfort of use.

[0044] Meanwhile, it is equipped with a central light source plate, a first ring light source, and a second ring light source, which helps to improve the lighting and decorative effect. Furthermore, when the ring lifting air guide platform is raised and lowered, the central light source plate and the first ring light source can achieve layered lighting, further enhancing the lighting and decorative effect, making it highly versatile.
