Firstly, electrofluid jet is formed on the basis of the electrofluid dynamics principle, then the micro-nano camera transmits images shot in real time to the computer in a signal mode, the computer compares image signals with standard images of three jet technologies of electric jet printing or electric spinning or electric atomization, the Boolean amount is transmitted to the technology switcher, and the technology switcher is connected with the micro-nano camera. The process switcher detects various parameters in the experiment in real time, calculates the optimal printing height of the jet behavior of electric jet printing or electric spinning or electric atomization by utilizing a built-in algorithm, and selects a stable printing height or adjusts to the optimal printing height according to the received Boolean amount; the process switcher transmits the calculated optimal height to the fluid controller in a fluid pressure signal mode, the fluid controller controls the jet behavior of electric jet printing or electric spinning or electric atomization in real time by controlling the height of the lifter, and finally three-dimensional rotation of the substrate in any direction is achieved through the universal rotator. According to the device for realizing the online switching of the electrofluid jet process, the printing height is controlled in real time by detecting and calculating experimental parameters, so that the online switching of three electrofluid jet processes of electrojet printing or electrospinning or electroatomization is realized; the preparation of different micro-nano structures is realized through the rotation control of the substrate in any three-dimensional direction and the adjustment of the motion platform.
