Abstract
The utility model belongs to a pen, in particular relates to a popular science demonstration pen using the principle of wind power generation. The utility model solves the problems of propagandizing and popularizing popular-science knowledge, because a general pen does not have an effect of initiating a user to think and generating a creative thought while using the pen. The utility model comprises at least one LED (1), a micro-generator (2), a pen shell (3) and impellers (4), wherein, the micro-generator (2) is fixed in the pen shell (3); the impellers (4) are exposed outside the pen shell (3), a shaft of the impellers (4) is connected with an input shaft of the micro-generator (2); at least one LED (1) is arranged on the external surface of the pen shell (3) and connected into a power supply circuit of the micro-generator (2) in parallel. The user makes the micro-generator generate current to drive the LED to light through rotating the impellers on the pen, thereby initiating people to think, and achieving the aim of propagandizing and popularizing popular-science knowledge.
Description
Technical field
The utility model relates to a kind of pen.
Background technology
At present, pen is of a great variety on the market, but great majority only have the simple function that writes, and does not reach people when writing, and allows the user cause thinking, produces the effect of innovative thinking let alone the popularization of popular science knowledge and moral.
The utility model content
The purpose of this utility model is can't allow the user when using in order to solve conventional pen, and the thinking of initiation is arranged, and produces the effect of innovative thinking, thereby conducts promotion to the problem of popular science knowledge.And then provide a kind of wind power generation principle science popularization demonstration pen.
The technical solution of the utility model is: wind power generation principle science popularization demonstration pen comprises at least one light emitting diode 1, microgenerator 2, a shell 3 and impeller 4, and described microgenerator 2 is fixed in the shell 3; The impeller 4 outer outsides that are exposed at a shell 3, the axle of impeller 4 is connected with the power shaft of microgenerator 2; Described at least one light emitting diode 1 is arranged on the outer surface of a shell 3 and is connected in the current supply circuit of microgenerator 2.
The utlity model has following beneficial effect: the utility model is that the electric current that utilizes built-in micro wind turbine generator to produce drives led lighting.The user needs only the slight outer blade of a shell that blows, and handwriting will sparkle, and the power of light changes along with the size of air-flow.So be provided with, can excite the user especially students in middle and primary schools the interest of popular science knowledge is promoted popular science knowledge, the user can cause thinking thus, helps the generation of innovative thinking.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.Fig. 2 is internal circuit configuration figure of the present utility model.Fig. 3 is the internal circuit configuration figure of the specific embodiment three.
The specific embodiment
The specific embodiment one: in conjunction with Fig. 1, Fig. 2 present embodiment is described, present embodiment is made up of light emitting diode 1, microgenerator 2, a shell 3 and impeller 4, and described microgenerator 2 is fixed in the shell 3; The impeller 4 outer outsides that are exposed at a shell 3, the axle of impeller 4 is connected with the power shaft of microgenerator 2; Light emitting diode 1 is arranged on the outer surface of a shell 3 and is connected in the current supply circuit of microgenerator 2.
The specific embodiment two: present embodiment is described in conjunction with Fig. 1, the difference of the present embodiment and the specific embodiment one is: the quantity of described light emitting diode 1 is two, two light emitting diodes 1 are separately positioned on the outer surface of a shell 3 left and right sides, are connected in parallel on the current supply circuit of microgenerator 2 after two light emitting diode series connection connect.
The specific embodiment three: present embodiment is described in conjunction with Fig. 3, the difference of the present embodiment and the specific embodiment one is: present embodiment has increased electric capacity 5, electric capacity 5 is in parallel with light emitting diode 1, and the purpose that increases electric capacity 5 is excessive in order to prevent voltage, burns light emitting diode 1.
