Abstract

一种水滴悬浮演示仪,属于教学科普仪器制造技术领域,采用风机、聚风罩、多孔整流风管和滴管头构成,多孔整流风管底部与聚风罩连接,聚风罩底部连接风机,滴管头在多孔整流风管上方的中部。教学演示时,启动风机,气流经过聚风罩和多孔整流风管,形成平衡稳定的向上气流,再操控滴管头滴出水滴,水滴与气流相遇,受气流影响悬浮在空中。本实用新型具有丰富的知识性和趣味性,构造直观,造价低,操作简便,演示生动直观。

Description

水滴悬浮演示仪
技术领域:
本实用新型属于教学科普仪器制造技术领域,是一种教学科普演示仪器。
背景技术:
日前,物理教学中主要是老师根据书本内容进行讲解,很少利用教学仪器进行演示,学生理解困难,如果采用合适的教学仪器边演示,边讲解,能够使学生更产生性趣,加深理解和记忆,可以达到事半功倍的效果。
发明内容:
本实用新型的目的是要提供一种水滴悬浮演示仪,从而便于学生对力的平衡有直观的了解。
本实用新型解决技术问题的方案是采用风机、聚风罩、多孔整流风管和滴管头构成水滴悬浮演示仪,多孔整流风管为管径和长度相同并且相互平行的风管组,底部与聚风罩连接,聚风罩为漏斗状,聚风罩底部连接风机,滴管头在多孔整流风管上方的中部。教学演示时,启动风机,气流经过聚风罩和多孔整流风管,形成平衡稳定的向上气流,再操控滴管头滴出水滴,水滴与气流相遇,受气流影响悬浮在空中。
形成这种现象的科学原理是一个物体受到两个力同时作用时,如果能够保持静止或匀速直线运动,说明物体处于平衡状态。使物体处于平衡状态的两个力叫做平衡力,作用在同一物体上的两个力,如果大小相等、方向相反,并且在同一条直线上,这两个力就彼此平衡。
本实用新型具有丰富的知识性和趣味性,构造直观,造价低,操作简便,演示生动直观。
附图说明:
附图为本实用新型剖视图。
具体实施方式:
本实用新型由风机1、聚风罩2、多孔整流风管3和滴管头4构成,多孔整流风管3为管径和长度相同并且相互平行的风管组,底部与聚风罩2连接,聚风罩2为漏斗状,聚风罩2底部连接风机1,滴管头4在多孔整流风管3上方的中部。
