Abstract

一种依靠气流加速而持续旋转的玩具陀螺,它是在玩具陀螺上沿径向设置翼片,当气流顺着玩具陀螺吹向翼片时,气流推动翼片,使陀螺的转动动能得到补充,而维持旋转。气流不断地吹向玩具陀螺翼片,该陀螺就能不停地旋转下去。

Description

持续旋转玩具陀螺
本实用新型是一种无动力玩具,它是能够借助气流,如嘴吹气而维持旋转的玩具陀螺。
目前,公知的无动力玩具陀螺,启动后依靠自身的惯性维持旋转。由于转动能不断损耗,陀螺转速逐渐降低,最终倒地停转。
本实用新型的目的是提供一种玩具陀螺,它不仅能够靠自身惯性维持一段时间的旋转,而且能够利用气流对陀螺进行加速,补充损耗的转动动能,维持陀螺不停地旋转。
本实用新型是这样实现的,在陀螺的径向对称设置几片翼片,当气流,如用嘴对着空心细管吹出的气流,顺着陀螺旋转的方向,流向翼片时,气流推动翼片,使陀螺的转动动能得到补充而加速旋转。不断地向翼片吹气,陀螺便维持旋转,不会倒地。
由于采用上述方案,可以通过气流冲击翼片而旋转陀螺不断得到能量补充,从而维持旋转,不致倒地停转。
下面结合附图和实施例对本实用新型进一步说明。
图1是本实用新型实施例的纵剖面构造图。
图2是本实用新型实施例的俯视图。

在实施例中,如图2所示,翼片(3)沿径向设置,当整个陀螺旋转以后,依靠自身惯性维持旋转,因为转动能的不断损耗,转速逐渐降低。顺着旋转方向(6),向翼片(3)吹气,气流(5)推动翼片(3),使整个陀螺得到能量补充,旋转加快。气流(5)越急,推力越大,陀螺旋转越快。不断提供气流(5),陀螺便会维持旋转,不会停转倒地。
