Description

A kind of novel bar magnet flying saucer moulding decorative toy device

Technical field

The utility model relates to a kind of decorative toy device, and particularly a kind of novel bar magnet flying saucer moulding decorative toy device belongs to decorative toy articles for use technical field.

Background technology

No matter be at films and television programs, still in the middle of people imagined, bar magnet flying saucer team was all magical abrim in the mankind, simultaneously, also stayed many mysteries of separating waited to the mankind.At present, among people's decorative toy, the decorative toy of relevant life, pet, the mankind, animals and plants and other subject matters like that can be found everywhere, and as the science fiction mystery, the decorative toy of plugging the bar magnet flying saucer class subject matter of imagination wing to people does not but have, and this can't but be a kind of matter of regret.

The utility model content

The purpose of this utility model is: a kind of novel bar magnet flying saucer moulding decorative toy device is provided, satisfying people's home decoration, when beautifying the environment, satisfy the curious desire of people more further, excite people that the exploration of tera incognita is desired more further novel bar magnet flying saucer.

The utility model realizes that the technical scheme that above-mentioned purpose adopted is: a kind of novel bar magnet flying saucer moulding decorative toy device, it is made up of flying saucer model, permanent magnet iron staff, rotating shaft, base, bearing, column, coil L1, coil L2, battery, wiring board, upper cantilever, transistor, adjustable resistance, switch, bar magnet flying saucer moulding decorative toy device has a permanent magnet iron staff, in the intermediate throughholes of permanent magnet iron staff rotating shaft is installed; In the inside of base battery, wiring board are installed, the external position of base is equipped with a switch; In the upper and lower position of column one coil L1 and coil L2 are installed successively, the side on the base vertical be equipped with column upper cantilever vertically is installed in column above, rotating shaft vertically is installed in opening in the shelves between base and the upper cantilever by bearing; One transistor and adjustable resistance are installed on the wiring board, there is a lead to interconnect between triode, adjustable resistance, battery, switch, coil L1 and the coil L2, form gap retaining circuit that shakes, its program each other is: coil L1 is with after coil L2 connects, the end of coil L1 and the base stage of triode are connected, an end that is connected in parallel on coil L2 after the series connection of battery and switch links to each other with the colelctor electrode of triode, but the power transformation group is connected in parallel on the two ends of coil L1, and the emitter stage of triode links to each other with the junction of coil L2 with coil L1.

Operation principle of the present utility model is: if when the moment of switch connection bar magnet the N utmost point be near the coil, the collector current of triode flows through coil L2, coil L2 can produce corresponding magnetic field, this magnetic field will produce attraction to its N utmost point of bar magnet, from but bar magnet rotation, as the N of bar magnet during extremely near coil L1, make and produce an electromotive force among the coil L1, thereby improved base bias, the electric current of colelctor electrode increases thereupon, and coil L2 is strengthened the attraction of the bar magnet N utmost point, bar magnet quickens rotation further, because effect of inertia, bar magnet rotates unceasingly, and the S that makes bar magnet is extremely near coil, make and produce a counter electromotive force among the L1, weakened the basis set bias voltage, collector current reduces thereupon, so that arrive zero.Do not have electric current to flow through among the coil L2, do not produce any attraction, bar magnet continues operation by inertia, and again near coil, so repeat above-mentioned process again, bar magnet just rotation constantly goes down up to the N utmost point.

Beneficial effect: a kind of novel bar magnet flying saucer moulding decorative toy device of the present utility model, people's home decoration can satisfied, when beautifying the environment, satisfy the curious desire of people more further, excite people that the exploration of tera incognita is desired more further novel bar magnet flying saucer.
