Fig. 2 is that the present invention fans header structure figure and illustrates;
In figure: 1, joint hinge, 2, upper cover, 3, lower cover, 4, fan head, 5, suspension rod, 6, flabellum, 41, rotating shaft, 42, upper bearing (metal), 43, upper cover, 44, stator, 45, external rotor, 46, lower cover, 47, lower bearing.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technological scheme in the embodiment of the present invention is clearly and completely described.Obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As depicted in figs. 1 and 2, a kind of small-sized household ceiling fan assembly, comprises joint hinge 1, and described joint hinge 1 bottom arranges upper cover 2; Described upper cover 2 side arranges suspension rod 5 and suspension rod 5 is fixedly connected with upper cover 2; Described suspension rod 5 bottom arranges lower cover 3; Described lower cover 3 side arranges flabellum 6; Described flabellum 6 one end fan 4 is set and flabellum 6 with fan 4 and be fixedly connected with; Described fan 4 inside arrange rotating shaft 41; Described rotating shaft 41 side arranges upper bearing (metal) 42 and upper bearing (metal) 42 is fixedly connected with rotating shaft 41; Described upper bearing (metal) 42 side arranges upper cover 43 and upper bearing (metal) 42 and upper cover 43 close contact; Described upper cover 43 side arranges external rotor 45 and external rotor 45 bottom arranges lower cover 46; Described lower cover 46 side arranges stator 44; Described stator 44 bottom arranges lower bearing 47 and lower bearing 47 and lower cover 46 close contact.
As optimisation technique scheme of the present invention: described suspension rod 5 is cylinder hollow structure, and is connected by suspension rod between upper cover 2 with lower cover 3; Described flabellum 6 one end embeds fan 4 inside; Described upper bearing (metal) 42 is for open circles loop configuration and rotating shaft 41 runs through upper bearing (metal) 42 inside; Described upper bearing (metal) 42 is connected by rotating shaft 41 with between lower bearing 47.
Ceiling fan motor, also known as fan 4, is the critical piece of ceiling fan.It is made up of stator 44, external rotor 45, ball bearing, upper cover 43, lower cover 47 etc.The difference of the present invention and desk fan motor adopts closed type external rotor 45 structure.The feature of this structure is that stator 44 is fixed in the middle of motor, and external rotor 45 rotates around stator 44, thus drives the fan that is attached thereto 4 to rotate together with shell.Flabellum 6 is arranged on fan 4, along with the rotation air-supply of fan 4.In use of the present invention, just be equivalent to a monopole asynchronous motor, cage rotor is encased the stator 44 being embedded with two phase windings, because single phase poaer supply can not produce rotating magnetic field, therefore one of them winding must reach the object of phase-splitting by series capacitor, the present invention reduces electric current by pressure regulation, controls rotating speed, the voltage x current size that conversion gear changes power-supply circuit reaches change motor speed, thus changes the speed of fan.The speed regulator of coil silicon chip is exactly an inductance, and alternating circuit is equivalent to resistance, divides to fall portion voltage electric current.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.Any reference character in claim should be considered as the claim involved by limiting.
The above; be only preferred embodiment of the present invention; not in order to limit the present invention, every above embodiment is done according to technical spirit of the present invention any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solution of the present invention.
