Microcapsule preparation method and microcapsule preparation device

The invention belongs to the technical field of microcapsule preparation, and discloses a microcapsule preparation method and a microcapsule preparation device. According to the method, an arranged high-voltage electrostatic spraying system is utilized, a hydrophilic solution atomizing nozzle and a lipophilic solution atomizing nozzle of the high-voltage electrostatic spraying system are connected with a high-voltage electrostatic generator, and a certain number of capsule material liquid drops can be combined to the outer walls of core material liquid drops through the electrostatic adsorption effect; when the charges carried by the capsule material liquid drops adsorbed by the core material liquid drops are equal to the charges carried by the core material liquid drops, fused liquid drops without charges are formed, and the fused liquid drops finally break away from the action of the electric field force to form microcapsule particles; in the process of mutual adsorption of the core material liquid drops an
