Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] Embodiment

[0029] See Figures 1 to 4 As shown, a bladeless fan light that blows air downward includes a circular support 1 and an air inlet protection net cover 2 provided on the top of the circular support. In this embodiment, the air inlet protection net cover can be a plastic structure or a metal structure, and the circular support is a light-transmitting plastic structure, which can cooperate with the annular light source plate to achieve edge lighting operation.

[0030] In this embodiment, a circular cavity 3 is provided at the center of the bottom surface of the circular support, and an air outlet annular groove 4 concentric with the circular cavity is provided on the circular support. Air guide plates 5 are fixedly arranged at equal intervals in the air outlet annular groove; the air outlet annular groove is mainly used for blowing air out, and the air guide plates are used for guiding air and at the same time for fixedly connecting both ends of the air outlet annular groove to make the circular support an integral body.

[0031] In this embodiment, a fan motor 6 is fixed in the circular cavity. The fan motor is fixed at the center of the circular cavity by screws. Above the circular support, there is a hemispherical fan support 7. At the edge of the top surface of the hemispherical fan support, there are several fan blades 8. The hemispherical fan support is connected to the main shaft of the fan motor. The hemispherical fan support and the fan blades are both plastic structures or can also be metal structures. When the hemispherical fan support rotates, it drives the fan blades to rotate and makes the air flow blow from top to bottom. At the connection between the air inlet protective net cover and the circular support, there is a light guide decorative ring 21. A light strip 22 is fixed on the inner wall of the light guide decorative ring. In actual application, a toothed groove is provided on the inner wall of the light guide decorative ring, and the light of the light strip passes through the toothed groove and irradiates outward from the light guide decorative ring, which can improve the lighting effect.

[0032] Moreover, in this embodiment, a central light source board 9 and a light-transmitting lamp cover 10 are fixed in the circular cavity. The central light source board is located below the fan motor. When in use, the fan motor drives the hemispherical fan support to rotate, and the fan blades drive the air flow to blow downward from the air outlet annular groove. The central light source board is fixed in the circular cavity by screws, and the light-transmitting lamp cover can be fastened or fixed by screws.

[0033] In this embodiment, an annular groove 11 is provided at the edge of the top surface of the circular support. On the bottom wall of the annular groove, there are several mounting hole columns 12. At the edge of the bottom surface of the air inlet protective net cover, a clamping convex column 13 is integrally formed at a position corresponding to the position of the mounting hole column. The clamping convex column is clamped in the circular hole of the mounting hole column and is positioned by several screw rods.

[0034] In this embodiment, a wire channel 15 is provided on the side wall of the circular cavity and on one of the air guide plates. A protective cover 16 is fixed on the wire channel by screws. When in use, the wire is arranged between the wire channel and the protective cover. With the above structure, the wire does not affect the normal blowing requirement.

[0035] In this embodiment, the bottom diameter of the hemispherical fan support is smaller than the inner diameter of the air outlet annular groove. Thus, when the hemispherical fan support rotates, the air flow can blow downward from the air outlet annular groove.

[0036] In this embodiment, a limit convex ring 17 for installing a drive is fixed to the top of the air inlet protection net cover. A buckle projection 18 is provided on the inner wall of the limit convex ring, and a positioning cover 19 is arranged inside the limit convex ring. An L-shaped groove 20 is provided on the side wall of the positioning cover. During assembly, the positioning cover is located inside the limit convex ring and rotated to make the buckle projection snap into the L-shaped groove for positioning. A drive box of the prior art can be installed inside the limit convex ring for power supply drive, and a U-shaped wire slot 14 is provided on the outer wall of the limit convex ring and the air inlet protection net cover. In this embodiment, the position of the U-shaped wire slot matches the position of the wire channel, and the wires of the drive power supply are connected to the central light source and the fan motor through the U-shaped wire slot and the wire channel, facilitating the wiring requirements.

[0037] The utility model has positive effects: The structure of the utility model is reasonably arranged. A circular concave cavity is provided at the center of the bottom surface of the circular support, and an air outlet annular groove concentric with the circular concave cavity is provided on the circular support. Guide vanes are fixedly arranged at equal intervals in the air outlet annular groove and cooperate with the fan motor, the hemispherical fan support and the fan blades. The air inlet protection net cover can protect the hemispherical fan support and the fan blades, and at the same time, air can be blown downward from the air outlet annular groove. A central light source plate and a light-transmitting lamp cover are fixed in the circular concave cavity, which can not only meet the lighting requirements, but also blow air downward from the edge of the central light source plate, ensuring the effectiveness of the air blowing, and also being beneficial to improving the use stability and reliability, reducing the assembly difficulty, making disassembly, assembly and maintenance more convenient, and having strong applicability.

[0038] The standard parts used in this embodiment can be directly purchased from the market. For the non-standard structural components described in the specification, they can also be directly processed without doubt according to the existing technical knowledge. At the same time, the connection methods of each component adopt the mature conventional means in the prior art, and the machines, parts and equipment all adopt the conventional models in the prior art, so no specific description will be made here.

[0039] Obviously, the above embodiments of the present utility model are only examples for clearly illustrating the present utility model, and are not limitations on the embodiments of the present utility model. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to enumerate all the embodiments here. And these obvious changes or modifications derived from the essential spirit of the present utility model still belong to the protection scope of the present utility model.
