[0002] A magnetic stirrer is a laboratory instrument used for liquid mixing. It is mainly used to stir or heat and stir low-viscosity liquids or solid-liquid mixtures at the same time. Its basic principle is to use the principle of like charges repelling and opposite charges attracting in the magnetic field, and use the magnetic field to push the magnetic stirrer placed in the container to rotate in a circle, thereby achieving the purpose of stirring the liquid.

[0003] In the relevant search, a magnetic stirring bioreactor with the authorization number CN208912076U includes a reaction tank body, a lifting ear and a support rod, etc. When the stirring shaft rotates, the arc-shaped stirring bar rotates accordingly. The stirring shaft is inclined in the reaction tank body. Compared with the vertical setting, the turbulence effect of the material in the reaction tank body can be better, and the upper and lower materials can be exchanged more, thereby improving the stirring effect of the material in the reaction tank body. After the stirring is completed, the inside of the reaction tank body is cleaned, the water inlet cover is opened, and the water is pumped into the water outlet ball along the water inlet pipe. The water sent in has a certain water pressure and will be sprayed from the water outlet hole to the inside of the reaction tank body, thereby cleaning the residue on the inner wall of the reaction tank body.
