MO source bottle switch structure

The invention provides an MO source bottle switch structure, and relates to the technical field of switch structures.The MO source bottle switch structure comprises an MO source bottle, a control assembly is fixedly installed at the upper end of the MO source bottle, a gas outlet pipe and a gas inlet pipe are installed at the upper end of the control assembly, and a short pipe and a long pipe are installed at the lower end of the control assembly; even if the pressure intensities inside and outside the source bottle are different, the pressure intensities inside the first vertical groove, the second vertical groove and the transverse groove are consistent as long as the third valve group is rotated and delayed for a period of time, at the moment, the first valve group is rotated again, liquid in the MO source bottle cannot flow back to the upper side under the pressure, and therefore the liquid is prevented from flowing back and flowing backwards when the MO source bottle is opened. 本发明提供一种MO源瓶开关结构，涉及开关结构技术领域
