Its beneficial effect is: due to for the energising of LED lamp panel, play illuminating effect when ceiling fan turns round, air-flow can make disk and LED lamp panel inhale tighter and tighter, therefore can realize the steadiness of disk and the assembling of LED lamp panel.
In some embodiments, flabellum can be six, and every flabellum inserts fastening place and is fixed on the outer rim of drain pan.
Its beneficial effect is: due to the sheet number of flabellum and the mounting type of flabellum, therefore can realize the increase of air quantity.
In some embodiments, flabellum can be made by aluminium plastic composite material.
Its beneficial effect is: because flabellum adopts aluminium plastic composite material, make flabellum lightweight, both met requirement of strength, adapted to again the use needs of rugged environment, can also increase air quantity.
The beneficial effects of the utility model are: air quantity is large, complete machine is reliable and stable.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of the brushless direct-current ceiling fan of the utility model one mode of execution;
Fig. 2 is the schematic cross-section of the brushless direct-current ceiling fan of the utility model one mode of execution.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 has schematically shown the brushless direct-current ceiling fan according to a kind of mode of execution of the present utility model.
As shown in Figure 1, 2, this brushless direct-current ceiling fan comprises outer rotor brushless DC motor 1, suspension rod axle 2, flabellum 3, drain pan 4 and top shell 5.
Flabellum 3 is six, by aluminium plastic composite material, made, the diameter of flabellum 3 can be chosen in 1.5m～2.28m, the quantity of flabellum 3 can be adjusted according to user demand, drain pan 4 fastens with top shell 5, flabellum 3 is distributed in fastening place 6, and every flabellum 3 inserts and fastens 6 places and be bolted the outer rim that is fixed on drain pan 5, has increased the air quantity of flabellum.
External rotor 7 is fixed in drain pan 4 and top shell 5, and the lower end of suspension rod axle 2 is passed and is supported on external rotor 7 by two rolling bearings 8, and external rotor 7 rotates along two rolling bearings 8, thereby drives drain pan 4, top shell 5 and flabellum 3 to rotate.
The upper end of suspension rod axle 2 is set with scaffold 9, scaffold comprises two cage plates 12 and a mounting plate 13, two cage plates 12 are symmetrically distributed in the both sides of mounting plate 13, two cage plates 12 are all welded in the bottom of mounting plate 13 by bending part 16, two cage plates 12 are all placed on the upper end of suspension rod axle 2 and connect 14 by two bolts to be fixed, and makes suspension rod axle 2 axial restraints.The top of mounting plate 13 is along three mounting holes 15 that are radially distributed with of suspension rod axle 2, mounting plate 13 is fixed with bolts on the girder of factory building by three mounting holes 15, make suspension rod axle 2 radially fixing, thereby while making ceiling fan high speed rotating, suspension rod axle 2 axially and be radially all subject to the supporting effect of scaffold 9, realized the stability of ceiling fan complete machine and the stable output of air quantity.
