Abstract
The utility model discloses an electric fan with a USB. The electric fan is characterized in that the electric fan comprises a direct current brushless motor, a motor shaft, a fan blade and a direct current brushless motor driving circuit; the motor shaft is arranged on the direct current brushless motor; the fan blade is connected with the motor shaft; and the direct current brushless motor driving circuit is electrically connected with the direct current brushless motor. A net cover is arranged outside the fan blade. The direct current brushless motor driving circuit comprises an AC-DC converting circuit. In the utility model, as the electric fan takes the direct current brushless motor as a driver, the advantage of the direct current brushless motor: long service life can be utilized to prolong the service life of the electric fan; when the direct current brushless motor is taken as the driver, compared with that the alternating current motor of the same power is used for driving the electric fan, the energy-saving efficiency of the product can be improved greatly; furthermore, by taking the direct current brushless motor as the driver, the noise can be reduced, the volume of the product can be reduced, and the structure is simple.
Description
Technical field
The utility model relates to a kind of electric fan, the electric fan that specifically a kind of family and office are used.
Background technique
Along with very big, often need an extra standby electric fan to come it is dispelled the heat.The focus that the working life of electric fan and energy-conservation situation are not to use the person to pay close attention to always, motor in the electric fan is to the working life and the energy-conservation important effect that plays of electric fan, existing electric fan all is to adopt motor directly to connect ac power supply to drive, and its shortcoming is to be subjected to the shortcoming that magnetic interference is big, working life short, power consumption is high, noise is big.How to solve the direction that above-mentioned shortcoming is the effort always of electric fan industry always.
Summary of the invention
The purpose of this utility model provides the electric fan of a kind of long service life, power consumption is low, noise is little band USB.
The purpose of this utility model is achieved through the following technical solutions.
A kind of electric fan with USB, it is characterized in that: described electric fan comprises dc brushless motor, motor shaft, flabellum and driven by Brush-Less DC motor circuit, motor shaft is positioned on the dc brushless motor, and flabellum links to each other with motor shaft, and the driven by Brush-Less DC motor circuit is electrically connected with dc brushless motor.
Described flabellum is provided with guard outward.
Described driven by Brush-Less DC motor circuit comprises ac-dc converter circuit.
The utility model compared with prior art has the following advantages:
Electric fan described in the utility model has been owing to adopted dc brushless motor as driving, the working life that can utilize the advantage of dc brushless motor long service life to improve electric fan; Use dc brushless motor as driving, compare, can significantly improve the energy-conservation effect of product with the driving of the AC motor of power as electric fan; Adopt dc brushless motor as driving the volume that can also reduce noise, reduce product, simple in structure.
Description of drawings
Fig. 1 is the structural representation of the electric fan of the utility model band USB.
Embodiment
Describe in further detail below in conjunction with the electric fan of accompanying drawing the utility model band USB.
As shown in Figure 1, the electric fan of band USB described in the utility model mainly is made up of with the driven by Brush-Less DC motor circuit dc brushless motor 1, motor shaft 2, flabellum 3.Motor shaft is positioned on the dc brushless motor, flabellum is installed on the motor shaft, the driven by Brush-Less DC motor circuit is electrically connected with dc brushless motor, drive circuit comprises ac-dc converter circuit, by the driven by Brush-Less DC motor circuit, can convert Ac to direct current, for dc brushless motor provides power supply.The outside of flabellum is provided with guard.By adopting dc brushless motor to drive, can improve the working life and the energy-conservation effect of electric fan, reduce noise, reduce small product size.
