Abstract
The utility model relates to an electric fan with a fixed lamp. The utility model adopts the technical proposal that a bushing is sleeved on a motor shaft and is fixedly connected with a motor cabinet, the lamp is installed on the bushing, S-pole or N-pole of an internal magnet is set between the bushing and the motor shaft, and is connected with the motor shaft; N-pole or S-pole of an external magnet is set outside the bushing, and is connected with a fan blade pedestal, and the external magnet is connected rotationally with the bushing through a steel ball. The utility model solves the deficiency in the prior art that the lamp, the motor shaft and the fan blade are rotated together to cause blinking luminous rays which lead human eyes to feel uncomfortable. With skillful design and simple structure, the utility model has the advantages that the lamp is not connected with the motor shaft, so that the lamp is not necessary to rotate along with the rotating motor shaft, thereby avoiding the problem of blinking luminous rays and having fine effect.
Description
Technical field
The utility model relates to a kind of electric fan, particularly a kind of electric fan with fixed light.
Background technique
Before the present utility model, existing electric fan, no matter be ceiling fan, desk fan, if lamp is installed thereon, then because motor shaft drives the flabellum rotation, lamp just can have illuminating effect before must being contained in electric fan again, therefore lamp can only be installed on motor shaft and the attachment, rotates with motor and flabellum.Like this, lamp rotates with motor shaft and flabellum, must cause the light flicker, and the eye of photograph is gleaming, and is very uncomfortable, and the time has been grown and can cause eye illness.Just because of the existence of this difficult problem, make the electric fan of band lamp can't drop into practical application.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned defective, designs a kind of electric fan of fixed light.
The technical solution of the utility model is:
The electric fan of band fixed light, its major technique is characterised in that socket one sleeve pipe on motor shaft, sleeve pipe is fixedlyed connected with motor cabinet, lamp is installed on the sleeve pipe, the internal magnet S or the N utmost point are set between sleeve pipe and motor shaft, and are connected, the external magnet N or the S utmost point are set outside sleeve pipe with motor shaft, and be connected with the flabellum base, external magnet is rotationally connected by steel ball and sleeve pipe.
Advantage of the present utility model is to utilize the magnet principle that motor shaft directly is not connected with flabellum with effect and connects by magnet, thereby sleeve pipe can be extended before the electric fan always, and lamp is installed on the sleeve pipe before the electric fan, lamp can be fixed and can and not rotate along with the motor shaft rotation.The utility model structure is ingenious, and the LED lamp is not rotated the influence of flabellum.
Description of drawings
Fig. 1--the utility model structural principle schematic representation.
Fig. 2--another schematic representation of the utility model structural principle.
Embodiment
As shown in Figure 1, motor 1 connects motor shaft 2, socket one sleeve pipe 3 on motor shaft 2, and sleeve pipe 3 can adopt metal such as iron etc. to make, and sleeve pipe 3 is fixedly connected on the motor cabinet (do not draw among the figure, omit), is not connected with motor shaft 2; On the top of sleeve pipe 3, promptly 2 is promptly anterior, and LED lamp 4 is installed on the sleeve pipe 3; Most critical be, an internal magnet 5 is set between motor shaft 2 and sleeve pipe 3, be connected with motor shaft 2, be assumed to be the S or the N utmost point; Connect on flabellum base 6, external magnet 7 is set, be assumed to be the N or the S utmost point, it is good adopting permanent magnet, exempts the trouble that electromagnet needs the cloth power line; Between flabellum base 6 and sleeve pipe 3, steel ball 8 is set again, flabellum base 6 can be rotated around sleeve pipe 3 by steel ball 8.
During use, when motor 1 rotation, drive motor shaft 2 rotations, but owing to LED lamp 4 is installed on the sleeve pipe 3, and be not connected with motor shaft 2, so LED lamp 4 does not rotate; Simultaneously, motor shaft 2 rotations, then drive the internal magnet 5 be attached thereto together, because it is the S or the N utmost point, then according to the magnetic principles that there is a natural attraction between the sexes, external magnet 7 in the flabellum base 6 outside sleeve pipe 3, the N or the S utmost point are subjected to the magnetic attraction of internal magnet 5, drive flabellum base 6 and on flabellum 9 rotations, this is the magnetic force follower, is around sleeve pipe 3 rotations by steel ball 8 during 6 rotations of flabellum base; Because what lamp adopted is LED lamp 4, its light has directivity, and stronger, therefore the influence of the flabellum 9 that is not rotated.
Shown in Figure 2 is that flabellum base 6 is by 8 rotations of the steel ball on the both sides of the cylinder 10 on the sleeve pipe 3, the same Fig. 1 of all the other structures.
Claims (4)
1. be with the electric fan of fixed light, it is characterized in that socket one sleeve pipe on motor shaft, sleeve pipe is fixedlyed connected with motor cabinet, lamp is installed on the sleeve pipe, the internal magnet S or the N utmost point are set between sleeve pipe and motor shaft, and are connected, the external magnet N or the S utmost point are set outside sleeve pipe with motor shaft, and be connected with the flabellum base, external magnet is rotationally connected by steel ball and sleeve pipe.
2. the electric fan of band fixed light according to claim 1 is characterized in that between sleeve outer wall and the external magnet steel ball being set, or connect cylinder on sleeve pipe, between external magnet both sides and the cylinder steel ball is set.
3. the electric fan of band fixed light according to claim 1 is characterized in that lamp is the LED lamp.
4. the electric fan of band fixed light according to claim 1 is characterized in that internal magnet, external magnet adopt permanent magnet.
