Description
Technical field
The utility model relates to a kind of fan, and particularly one is novel can outside speed-governing dc brush-less fan.
Background technique
Fan, as a kind of air bells conditioner, is all often used by people at life and work.As: lower the temperature in life, in work, accelerate air circulation.
Existing fan structure is simple, is provided with carbon brush, and produce and be difficult to assembling, cost of production is high.When using, regulate its rotating speed inconvenient, restive.
In using, energy consumption is high, and user cost is high.
Model utility content
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provide a kind of novel can outside speed-governing dc brush-less fan.
To achieve these goals, the measure taked of the utility model:
A kind of novel can outside speed-governing dc brush-less fan, comprise fan housing, in described fan housing, axle core is installed, axle core outer cover is provided with spring, ball bearing and clasp, axle core outside is provided with iron core by upper fixed plate and lower fixed plate, iron core is connected with pcb board by copper pin, and iron core outside is provided with fan leaf by magnet overcoat and rubber magnetic stripe;
Described pcb board is provided with outside speed-regulating control circuit.
The beneficial effects of the utility model: practical, cost of production is low, easy to use, structure is simple, and assembling is quick, and without the need to carbon brush, long service life, energy efficient, can carry out the control of rotating speed speed by external signal, be easy to speed governing.
Accompanying drawing explanation
Fig. 1, plane structure schematic diagram of the present utility model.
Embodiment
A kind of novel can outside speed-governing dc brush-less fan, comprise fan housing 1, in described fan housing 1, axle core 5 is installed, axle core 5 outer cover is provided with spring 10, ball bearing 11 and clasp 12, axle core 5 outside is provided with iron core 6 by upper fixed plate 7 and lower fixed plate 8, iron core 6 is connected with pcb board 13 by copper pin 9, and iron core 6 outside is provided with fan leaf 2 by magnet overcoat 3 and rubber magnetic stripe 4.
Described pcb board 13 is provided with outside speed-regulating control circuit.
Make the utility model can carry out speed governing by external signal, by the Signal transmissions of outside on outside speed-regulating control circuit, realize adjusting rotary speed.The rotating speed speed realizing hommization controls, thus has saved energy consumption.
