Abstract

本发明属于化学仪器技术领域，具体涉及一种防倒吸洗气瓶。本发明主要解决现有洗气瓶易倒吸、易污染等问题。本发明采取的技术方案为：一种防倒吸洗气瓶，包括洗气瓶，在洗气瓶上的瓶塞上设有进气管和出气管，其中：在进气管内的中下部设有一个半径小于进气管半径的防倒吸管，所述防倒吸管通过多个连接杆与进气管相连接，且进气管与防倒吸管之间的空腔与进气管是相通的。本发明具有结构简单、不易倒吸、不易污染的优点。

Description

一种防倒吸洗气瓶
技术领域
本发明属于化学仪器技术领域，具体涉及一种防倒吸洗气瓶。 
背景技术
洗气装置是化学实验中较常见的仪器之一。化学反应中气体的制备反应较多，但是在制备的过程中往往需要加热、浓酸等剧烈的条件，特别是在加热这种条件下，在反应结束后，由于操作人员的疏忽等原因，未及时撤离洗气装置，由于热胀冷缩的原因，洗液会被倒吸，从而污染仪器和反应物的同时，导致玻璃仪器炸裂，存在安全隐患。 
发明内容
本发明主要针对现有洗气瓶易倒吸、易污染等问题，提供一种结构简单、不易倒吸、不易污染的防倒吸洗气瓶。 
本发明为实现上述目的而采取的技术方案为： 
一种防倒吸洗气瓶，包括洗气瓶，在洗气瓶上的瓶塞上设有进气管和出气管，其中：在进气管内的中下部设有一个半径小于进气管半径的防倒吸管，所述防倒吸管通过多个连接杆与进气管相连接，且进气管与防倒吸管之间的空腔与进气管是相通的。 
本发明采用上述技术方案，可以提供一种防倒吸洗气瓶，在具体的实验室操作过程中，就算是反应结束后未及时撤离，洗液由于热胀冷缩的关系从导管倒流，在页面将外侧玻璃管露出来后就形成了一个瓶内微循环，自己留下来，不会继续往上倒吸。 
附图说明
图1是本发明的结构示意图； 
图2是防倒吸管的结构示意图。 
具体实施方式
实施例1 
如图1所示，一种防倒吸洗气瓶，包括洗气瓶1，在洗气瓶1上的瓶塞2上设有进气管3和出气管4，其中：在进气管3内的中下部设有一个半径小于进气管3半径的防倒吸管5，所述防倒吸管5通过多个连接杆6与进气管3相连接，且进气管3与防倒吸管5之间的空腔7 与进气管3是相通的。
