Abstract

一种伯努利原理演示装置，是一种教学用具，由吸管和纸漏斗组成。将一段吸管与一个纸漏斗相连接。本发明可以很方便地用于中小学生的教学使用，便于学生动手体验伯努利原理。

Description

简易伯努利原理演示装置
所属技术领域
本发明涉及一种教学用具，尤其是一种伯努利原理演示装置。 
背景技术
目前，通常的伯努利原理演示装置都很复杂，其存在的缺陷是：成本太高，不便于学生动手体验。
发明内容
为了克服现有伯努利原理演示装置的以上不足, 本发明提供了一种简易伯努利原理演示装置，可以解决上述问题。
本发明解决其技术问题所采用的技术方案是：将一段吸管与一个纸漏斗相连接。
本发明的有益效果是：可以很方便地用于中小学生的教学使用，便于学生动手体验伯努利原理。
附图说明
下面结合附图和实施例对本发明进一步说明。
附图是本发明的结构示意图。
图中1.吸管，2.乒乓球，3.纸漏斗。
具体实施方式
将一个吸管1的弯头部分与一个纸漏斗3固定连接。
演示时将一个乒乓球2放在纸漏斗3的下面，用嘴用力吹吸管1的另一端，由于伯努利原理，乒乓球2就会悬停在纸漏斗3的下面。
