Abstract

The invention relates to an LED pinwheel the blade of which is soft, thus the invention is not easy to hurt children and safe, and the cute casper enables people to have good emotion when looking at the pinwheel. Blades of two types of structures are arranged at intervals, when children run while taking along with the pinwheels, the wind wheels rotate rapidly, and the blades drive a smile face to rotate rapidly, so that a microgenerator coverts wind energy into electric energy, the current is contacted to a spring strip through wires, the blades rotate until being contacted with the spring strip to supply power to a copper matrix circuit and light an LED paster, then the pinwheel shines. The LED paster on the blades is an LED with low power, saves electricity and energy; the wind energy is converted into electric energy to light the LED paster, the power supply is not used; and the invention is convenient to use. The LED pinwheel can also be used as ornament of commercial shops.

Description

A kind of LED toy windmill

Technical field

Summary of the invention

The object of the present invention is to provide the beautiful LED toy windmill of a kind of fashion.

The structure division of LED toy windmill comprises: fan blade 1, and spring leaf 2, conduit 3, microgenerator 4, handle lid 5, self-tapping screw 6, handle fork 7, bolt 8, nut 9, the smiling face 10, wind wheel 11, footstalk 12, LED paster 13, copper base circuit 14, lead 15.

Fan blade 1 is made by flexible plastic, fan blade 1 has two kinds of structures, wherein copper base circuit 14 is imbedded in a kind of centre position of fan blade, on the copper base circuit 14 LED paster 13 is arranged, there are not copper base circuit 14 and LED paster 13 on the another kind of fan blade, there is the fan blade 1 of 1, two kind of structure of six fan blades to install at interval on the wind wheel 11; Fan blade 1 is connected on the smiling face 10 by bolt 8 and nut 9, when windmill rotates, smiling face 10 drives the generating of microgenerator 4 quick rotation, lead 15 is arranged in the conduit 3, lead 15 welds together with spring leaf 2 and is fixed on the conduit 3, and the electricity that microgenerator 4 sends leads on the spring leaf 2 by lead 15, when fan blade 1 forwards a position to copper base circuit 14 and spring leaf 2 is connected, just can give copper base circuit 14 power supplies, LED paster 13 will be luminous; Microgenerator 4 is fixed between handle lid 5 and the handle fork 7; Handle lid 5 is connected with handle fork 7 usefulness self-tapping screws 6, and self-tapping screw 6 has three, one of afterbody, each one on both sides; Wind wheel 11 has five, and four all around, middle one, the structure of wind wheel is in full accord all around, the structure of middle wind wheel and their basically identicals, and just the distance of pitching between 7 at fan blade 1 and handle lid 5, handle has strengthened, four wind wheels are preceding all around, a middle wind wheel after; The handle lid 5 of a middle wind wheel is different with other four wind wheel shapes with handle fork 7, and its handle lid 5 is exactly the handle fork 7 of other four wind wheels, and its handle fork 7 is exactly a footstalk 12.

A kind of LED toy windmill of the present invention advantage:

Fan blade is soft, is not easy to hurt baby, relatively safety.Add lovely casper, allowing the people look in a good humor.Baby runs, and wind wheel not only rotates can also be luminous, and particularly evening, it is more beautiful to send motley light, and baby prefers.The LED paster is a low-power LED, the power and energy saving, and wind energy transformation is an electric energy, lights the LED paster, and is without power supply, easy to use.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is further described:

Fan blade 1 is made by flexible plastic, fan blade 1 has two kinds of structures, wherein copper base circuit 14 is imbedded in a kind of centre position of fan blade, on the copper base circuit 14 LED paster 13 is arranged, there are not copper base circuit 14 and LED paster 13 on the another kind of fan blade, there is the fan blade 1 of 1, two kind of structure of six fan blades to install at interval on the wind wheel 11; Fan blade 1 is connected on the smiling face 10 by bolt 8 and nut 9, when windmill rotates, smiling face 10 drives the generating of microgenerator 4 quick rotation, lead 15 is arranged in the conduit 3, lead 15 welds together with spring leaf 2 and is fixed on the conduit 3, and the electricity that microgenerator 4 sends leads on the spring leaf 2 by lead 15, when fan blade 1 forwards a position to copper base circuit 14 and spring leaf 2 is connected, just can give copper base circuit 14 power supplies, LED paster 13 will be luminous; Microgenerator 4 is fixed between handle lid 5 and the handle fork 7; Handle lid 5 is connected with handle fork 7 usefulness self-tapping screws 6, and self-tapping screw 6 has three, one of afterbody, each one on both sides; Wind wheel 11 has five, and four all around, middle one, the structure of wind wheel is in full accord all around, the structure of middle wind wheel and their basically identicals, and just the distance of pitching between 7 at fan blade 1 and handle lid 5, handle has strengthened, four wind wheels are preceding all around, a middle wind wheel after; The handle lid 5 of a middle wind wheel is different with other four wind wheel shapes with handle fork 7, and its handle lid 5 is exactly the handle fork 7 of other four wind wheels, and its handle fork 7 is exactly a footstalk 12, specifically sees accompanying drawing 3 and accompanying drawing 4.

A kind of LED toy windmill of the present invention operation principle:
