Abstract
Proposed by the present invention is a kind of blower fan of electromagnetic drive flabellum.Circular magnet coil is fixed with the Fan casing inwall provided with air outlet, arc-shaped permanent magnet is fixed with flabellum outer end equipped with more than two pairs of flabellum by sharf in Fan casing.Blower fan coverboard is housed in Fan casing opposite side, inlet scoop is provided with blower fan coverboard, bearing is housed on inlet scoop.The flabellum is tabular or arc shape.The Fan casing is manufactured using insulating materials.Because the present invention is in wind wheel of the Fan casing built with electromagnetic drive, so be not used in outside casing preparing motor and transmission mechanism, so it is simple in construction, it is easy to manufacture, and also energy conversion rate is high, and without mechanical loss, and running noise is low, is conducive to environmental protection.Higher blower fan application suitably is required to fan operation.
Description
Technical field
It is used for the blower fan of a kind of electromagnetic drive flabellum for producing blast the present invention is to provide mechanical field.
Background technology
Existing blower fan is generally direct transferred using motor or drives flabellum to operate by transmission mechanism, produces blast, by
The outside of Fan casing is arranged in the motor for driving, space-consuming is big, high noise, and machine driving frictional force is big, effect
Rate is low, is not easy to miniaturization, and use occasion is restricted.
The content of the invention
In order to overcome the shortcoming that prior art is present, the invention provides a kind of blower fan of electromagnetic drive flabellum.The blower fan
By installing the wind wheel with flabellum and permanent magnet in Fan casing, the technical problem that blower fan drives without motor is solved.
The present invention solves the scheme that is used of technical problem：
Circular magnet coil is fixed with the Fan casing inwall provided with air outlet, two are equipped with by sharf in Fan casing
Flabellum to more than, arc-shaped permanent magnet is fixed with flabellum outer end.
Blower fan coverboard is housed in Fan casing opposite side, inlet scoop is provided with blower fan coverboard, bearing is housed on inlet scoop.
The flabellum is tabular or arc shape.
The Fan casing is manufactured using insulating materials.
Good effect, because the present invention is in wind wheel of the Fan casing built with electromagnetic drive, so being not used in preparing outside casing
Motor and transmission mechanism, thus it is simple in construction, it is easy to manufacture, and energy conversion rate is high, without mechanical loss, and operates
Noise is low, is conducive to environmental protection.Higher blower fan application suitably is required to fan operation.
Brief description of the drawings
Fig. 1 is diagrammatic cross-section of the present invention.
In figure, 1. Fan casings, 2. air outlets, 3. circular battery coils, 4. sharfs, 5. flabellums, 6. arc-shaped permanent magnets.
Embodiment
According to the figure, circular magnet coil 3 is fixed with the inwall of Fan casing 1 provided with air outlet 2, in Fan casing
More than two pairs of flabellum 5 is housed by sharf 4, arc-shaped permanent magnet 6 is fixed with flabellum outer end.
Blower fan coverboard is housed in Fan casing opposite side, inlet scoop is provided with blower fan coverboard, bearing is housed on inlet scoop.
The flabellum is tabular or arc shape.
The Fan casing is manufactured using insulating materials.
Technical principle：
Circular magnet coil produces unidirectional electric field after being powered, the arcuate permanent magnetic of close installation therewith in the presence of unidirectional electric field
Body is moved by magnetic fields to electric field moving direction, so as to drive flabellum to rotate, accelerates the air of suction, forms blast, is led to
Cross air outlet outflow.
The relative motion of circular magnet coil and arc-shaped permanent magnet, arcuate movement track is changed into equal to linear electric motors
Ring-type motor.
Feature：
Due in wind wheel of the Fan casing built with electromagnetic drive, so being not used in outside casing preparing motor and transmission mechanism, institute
It is easy to manufacture with simple in construction, and energy conversion rate is high, and without mechanical loss, and running noise is low, is conducive to environmental protection.
Blower fan of the present invention is particularly suitable for small occasion and used, and is especially used on automatic controls and computer.
