Description
Technical field
The utility model relates to a kind of electricity didactical game device.
Background technology
Existing electricity teaching demonstration device of less types, function singleness, and also cost is higher, causes the application implementation scope wideless, and quality of instruction has been produced influence.And existing game device is main with amusement mostly, the intellectual characteristics of ignoring, and the game device of electricity is few especially.
The utility model content
The purpose of the utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of cost low, applied widely, the electricity didactical game device of teaching through lively activities.
A kind of electricity didactical game device that the utility model provides comprises electromagnetic induction device and voltage doubling rectifing circuit unit; Electromagnetic induction device is made up of bar magnet and coil L; Said coil L is connected on the voltage doubling rectifing circuit unit, and said voltage doubling rectifing circuit unit is by capacitor C 1, C2, diode D1, D2; Light emitting diode D and K switch constitute; Coil L and capacitor C 1, diode D2, light emitting diode D and K switch are in series, and diode D1 is connected on capacitor C 1 and the diode D2 series connection point by end, and capacitor C 2 is connected on the series connection point of diode D2 and light emitting diode D.
The utility model combines electromagnetic induction and voltage doubling rectifing circuit, and low-voltage, the weak current of utilizing electromagnetic induction to produce are charged to electric capacity through the voltage multiplying rectifier continuous several times, make electric capacity obtain high voltage, high electric energy.So just can fully show diode and have unilateral conduction; Electric capacity has store electrical energy and the function that discharges and recharges.The electric energy that electric capacity stores, through the light-emitting diodes tube discharge, the flash of light of sending; Can demonstrate out semiconductor light emitting and have energy-conservation characteristics; Can embody the interest of the whole process of playing again, make the student produce curious sense, excite interest the study electronic technology to electronic technology.

Fig. 1 is the circuit theory diagrams of the utility model.
Embodiment
Below in conjunction with specific embodiment, the utility model is further specified.Should be understood that following examples only are used to the utility model is described but not the scope that is used to limit the utility model.
Embodiment 1
Referring to Fig. 1, a kind of electricity didactical game device that the utility model provides comprises electromagnetic induction device and voltage doubling rectifing circuit unit; Electromagnetic induction device is made up of bar magnet and coil L; Said coil L is connected on the voltage doubling rectifing circuit unit, and said voltage doubling rectifing circuit unit is by capacitor C 1, C2, diode D1, D2; Light emitting diode D and K switch constitute; Coil L and capacitor C 1, diode D2, light emitting diode D and K switch are in series, and diode D1 is connected on capacitor C 1 and the diode D2 series connection point by end, and capacitor C 2 is connected on the series connection point of diode D2 and light emitting diode D.
Embodiment 2
When bar magnet moves back and forth in coil L; Produce induction current among the coil L; When certain half cycle electric current was flowed out by a of coil L end, diode D2 ended, electric current through diode D1 to capacitor C 1 charging; In capacitor C 1, capacitor C 1 voltage equals coil L voltage with this half cycle electrical power storage.
When in addition the half cycle electric current was flowed out by the b end of coil L, diode D1 ended, and the electric energy that stores the electric current that goes out from coil midstream and the capacitor C 1 together, through diode D2 capacitor C 2 is charged together is stored in the electric energy of two half cycles in the capacitor C 2.Because coil and capacitor C 1 are to be connected in series, so the voltage on the capacitor C 2 is the voltage sum on coil voltage and the capacitor C 1, be two times of coil voltage, the voltage on the capacitor C 2 gets a promotion.
After letting bar magnet in coil, intert for several times back and forth during experiment, Closing Switch K again, light emitting diode D is luminous.
