Auxiliary device for chemical experiment

The invention discloses an auxiliary device for chemical experiments, which comprises a lifting mechanism for adjusting the overall height of the device, moving mechanisms for driving the device to move, and a heating mechanism for accelerating chemical reaction, the moving mechanisms are mounted on two sides of the lifting mechanism, and the heating mechanism is fixed above the lifting mechanism. Through arrangement of the gas suction mechanism, harmful gas generated during reagent reaction enters the liquid storage tank for purification along a gas suction cover, a rotating pipe, a first fixed shell and a gas conveying pipe under the action of a gas extractor, so that human health is protected from being affected, and the angle of the gas suction cover can be adjusted according to use requirements; and the dissipation of harmful gas can be avoided to the greatest extent. 本发明公开了一种化学实验用辅助装置，包括用于对装置整体高度进行调节的升降机构、用于带动装置移动的移动机构、用于加速化学反应的加热机构，所述升降机构两侧安装有所述移动机构，所述升降机构上方固定有所述加热机构。本发明通过设置吸气机构，试剂反应时产生的有害气体在抽气机的作用下沿吸气
