Specific embodiment
Below with reference to each attached drawing, by specific embodiment, the utility model in detail, completely describe.
It please refers to shown in Fig. 1-7, the utility model provides a kind of air blowing gyro, including rotating seat 1 and several has arc
The fan blade 2 of degree, the bottom of rotating seat 1 are equipped with rotation protrusion 11, and air blowing gyro is former when using rotation protrusion 11 as rotation fulcrum
Ground rotation or small range rotation, the both ends of fan blade 2 are respectively connecting pin 21 and free end 22, and several fan blades 2 pass through connecting pin 21
It tilts and the circumferential direction along rotating seat 1 is uniformly arranged with interval, the free end 22 of each fan blade 2 is upward.Using air blowing
Driving rotation is structurally and operationally simply suitble to age lesser child of tender age to use, and interest is strong, is conducive to the exploitation of intelligence,
And the lung capacity of user can be tempered.In use, forming concave arc since the free end 22 of each fan blade 2 is bent upwards
Face, when user blows from the top of air blowing gyro, the wind surface surface pressure of fan blade 2 is increased, and is formed and 2 back side low pressure of fan blade
The draught head in area, this air pressure official post fan blade 2 obtain power, and since several fan blades 2 tilt and are arranged with interval, air-flow is logical
When crossing the gap between adjacent fan blade 2, the power of horizontal direction is generated, promotes fan blade 2 to rotate around rotation protrusion 11, reaches drive
The purpose of the rotation of dynamic air blowing gyro.
The free end 22 of fan blade 2 is more roomy than connecting pin 21, and the concaved circular cambered surface for forming fan blade 2 and rotating seat 1 has larger
Surface area, and guarantee that the gap between adjacent fan blade 2 is suitable for, so that the draught head between the wind surface and the back side of fan blade 2 can
To be effective as the power of driving gyro rotation.
It please refers to shown in Fig. 3, Fig. 4 and Fig. 6, the shape of fan blade 2 is petal 201, chopper shape 202 or sickle-shaped 203, is made
The good appearance of air blowing gyro, and fan blade 2 can effectively cut air, guarantee air flow property, to guarantee air blowing gyro
Rotate duration.
Rotating seat 1 is disc, and rotation protrusion 11 is located at the center location of 1 bottom of rotating seat.Discoidal rotating seat 1 is protected
The resistance that card air blowing gyro is subject to when rotated is smaller, so that the time longest of its rotation.Rotation protrusion 11 is located at rotation
The center location of 1 bottom of seat can be such that the centripetal force of air blowing gyro when rotated always perpendicular to shaft, is biased in air blowing gyro
When, the resultant force of centripetal force and gravity makes the rotation of air blowing gyro recovery vertical direction.
The radius of rotating seat 1 is R1, and the endpoint of several 2 free ends 22 of fan blade forms the circle concentric with rotating seat 1, and radius is
R2, and R2/R1=3-6 guarantee that the rotation of air blowing gyro is more light.
The cross section of rotation protrusion 11 is circle, and the radius of the cross section of rotation protrusion 11 is gradually reduced from top to bottom, blows
The air drag very little of gas gyro when rotated, air blowing can promote gyro constantly to promote speed, and gyro can maintain for a long time
Rotation.
The lower surface of the upper surface of rotating seat 1, the upper surface of fan blade 2 or fan blade 2 is equipped with decorative pattern or pattern, makes to blow
The shape of gyro is more aesthetically pleasing, to improve the attraction to child of tender age.
Rotating seat 1 and the material of fan blade 2 are identical or different, are metal, resin or plastics.Preferably, rotating seat 1 and fan blade
2 material is plastics, easily manufactured, cheap and lightweight and convenient transport installation.
Rotating seat 1 is an integral structure with several fan blades 2, and manufacture craft is simple, solid firm, it is not easy to damage.But no
It is limited to this, rotating seat 1 and several fan blades 2 are also possible to split type structure, when rotating seat 1 or fan blade 2 are damaged, Ke Yijin
Row replacement, economizes on resources, the utility model is not construed as limiting this.
The above is only the preferred embodiment of the present invention, not thereby limits the patent protection of the utility model
Range, it is all with equivalent structure transformation made by the utility model specification and accompanying drawing content, directly or indirectly it is used in it
His relevant technical field similarly includes within the protection scope of the present utility model.
