Abstract
The invention discloses a kind of hand held DC fan, including handle, fan blade, fan housing, direct-flow micromachine, battery and power switch, fan housing is located at one end of handle, direct-flow micromachine is located in fan housing, fan blade is located on the output shaft of direct-flow micromachine, battery is located in handle, provides power supply for direct-flow micromachine, power switch is located on handle.Due to the structure using above-mentioned small-sized hand held DC fan, small-sized fan can be so that against oneself blowing, very convenient and practical, the used time can not be placed in pocket or in bag small-sized fan, very convenient to carry in hand held.
Description
Technical field
The present invention relates to a kind of fan, specifically a kind of DC fan.
Background technology
It is very hot without the place of air-conditioning, fan in summer, but it is inconvenient with oneself with existing AC system fan,
Moreover in the place of no alternating current, existing big fan can not also use, and in order to solve this problem, therefore have developed a kind of hand
Drot gfasplng DC fan.
The content of the invention
It is an object of the invention to provide a kind of hand held DC fan handy to carry about.
To achieve the above object, the technical solution adopted in the present invention is：
Hand held DC fan, including handle, fan blade, fan housing, direct-flow micromachine, battery and power switch, fan housing are located at hand
One end of handle, direct-flow micromachine are located in fan housing, and fan blade is located on the output shaft of direct-flow micromachine, and battery is located at handle
It is interior, power supply is provided for direct-flow micromachine, power switch is located on handle.
Beneficial effects of the present invention：Due to the structure using above-mentioned small-sized hand held DC fan, small-sized fan can
So that against oneself blowing, very convenient and practical, the used time can not be placed in pocket or in bag small-sized fan, take in hand held
With very convenient.
