Description
Technical field
The utility model relates to toy technique field, specifically a kind of optical pressure windmill didactical doll.
Background technique
Now with continuous improvement of people's living standards, the toy of children is also more and more, but object for appreciation on the market now
Tool generally all emphasizes entertainment and playability, plays educational function during cannot being at play, can not be at play middle basis
Phenomenon acquires scientific knowledge, does not accomplish to teach through lively activities.
Utility model content
The utility model will solve the above-mentioned problems of the prior art, provide a kind of optical pressure windmill didactical doll, solve
The problem of the difference of traditional toy science popularization at present, meets the needs of of teaching through lively activities.
The utility model solves the technical solution of its technical problem use: this optical pressure windmill didactical doll, including positioning
Plate is fixed with hand generator on positioning plate, and headlamp, hand generator and headlamp are connected on positioning plate in positioning backboard
Face is connected, and hollow ball made of transparent glass is equipped in front of headlamp, is rotatably connected to windmill, circumference on windmill in hollow ball
The sheet blade of one group of rich center of circle rotation is distributed with, sheet leave dual sides are respectively black and white, adjacent sheet blade it
Between front and back sides be oppositely arranged.After being arranged in this way, hand generator hand power shines for headlamp, and headlamp shines across hollow ball
It penetrates on the front and back sides in sheet blade, since sheet leave dual sides are respectively black and white, suction of the black and white to light
The optical pressure that yield difference causes the front and back sides of sheet blade to be subject to has a difference, and windmill be housed in hollow ball do not have it is additional outer
The interference of boundary's factor, the front and back sides of sheet blade, which form pressure difference, then rotates windmill, and black and white can maximize increasing
The pressure difference of sheet leave dual sides allows windmill quick start to operate, and children can see the rotation feelings of windmill through hollow ball
Condition, it is thus understood that the presence and application of optical pressure, significant effect are taught through lively activities.
As the further improvement of utility model, hollow ball bottom is fixed with fixed link, is equipped with tip-like at the top of fixed link
Needle tip, windmill center is equipped with nut cap, and nut cap covers on needle tip, and there are gaps between nut cap inner wall and fixed link.It is fixed
There was only end in contact before needle tip between bar and nut cap, greatly reduces the friction between fixed link and nut cap, reduce windmill to light
According to the minimum requirements of intensity, make windmill rotation more remarkable fluency.
As the further improvement of utility model, positioning plate is vertically arranged, and positioning plate is equipped with through slot, vertical on positioning plate
Embedded with level board, headlamp and hollow ball are fixed on level board, and hollow ball partially passes through through slot to positioning back.It is positioning
Hollow ball is fixed on plate and needs biggish space, can occupy additional space, is not easy to the installation arrangement of other parts, positioning plate
It is vertically arranged and the through slot by getting through positioning plate, hollow ball latter half is tucked into through slot, can be greatly reduced hollow
Ball occupied space reduces entire toy volume.
As the further improvement of utility model, be fixed with hemispheric transparent protective cover on positioning plate, headlamp and
Hollow ball is respectively positioned in protective cover.Since headlamp and hollow ball are easy to be damaged by external force, and protective cover can play every
Effect from protection, protective cover are transparent still can intuitively to see windmill rotation situation from external.
As the further improvement of utility model, headlamp is close to hollow ball side end surface, and sheet blade is in the horizontal plane
Rich center of circle rotation.Headlamp can effectively reinforce intensity of illumination close to hollow ball, increase optical pressure, provide bigger move for windmill rotation
Power, rich center of circle rotation makes each sheet blade light can be avoided by other sheet by illumination to sheet blade in the horizontal plane
Leaf baffle, the optical pressure being subject to is more uniform, rotates more powerful.
As the further improvement of utility model, loudspeaker are fixed on positioning plate, loudspeaker parallel connection accesses hand generator
Electricity-generating circuit.Loudspeaker can play music when hand generator generates electricity, and improve the attraction to children；Loudspeaker parallel connection access electricity
Road will not interfere the normal work of headlamp loudspeaker damage, and can bring open circuit wind when loudspeaker damage if connecting
Danger.
As the further improvement of utility model, air is extracted inside hollow ball and forms class vacuum state.The class of hollow ball
Vacuum state can reduce the resistance encountered when the rotation of sheet blade, keep windmill rotation more smooth, rotates effe is more preferable.
As the further improvement of utility model, positioning plate dorsal edge is evenly equipped with one group of support leg, and support leg height is high
In positioning plate behind protruding parts height.Support leg can play a supporting role when laying flat, and can also individually make when placing vertically
For the connecting pin of wall hanging, it is contemplated that positioning plate has some positions outstanding behind, and support leg can play the high positioning plate of frame
Effect, avoids positioning plate from having protruding parts behind and directly contacts with bottom surface, and protection positioning plate has protruding parts behind.
The utility model has the advantages that: the utility model it is structurally reasonable, compact, pass through the hand hair of hand generator
Electricity shines for headlamp and is radiated on sheet blade, since sheet leave dual sides are respectively black and white, black and white
It causes optical pressure poor the absorptivity difference of light, pushes windmill rotation, can intuitively see windmill rotation situation, understand optical pressure and know
Know, teaches through lively activities.
