The invention discloses an airflow assisted internal conical surface distributed electrostatic spinning nozzle which belongs to the field of electrostatic spinning and mainly comprises a receiving plate, an electrical heating device, an airflow guide column, a screw, a gas interface block, a distributing plate, a chocked flow block, an internal conical surface nozzle body, a nozzle body locating pin, a temperature sensor, an airflow nozzle, a grounding electrode and a high-pressure electrostatic generator, wherein the side surface of the upper end of the internal conical surface nozzle body is provided with a spinning medium inlet and is used for being connected with a distributing plate runner, and a gap between the internal conical surface nozzle body and the airflow guide column is used for guiding a spinning medium so that the spinning medium is uniformly distributed on the internal conical surface on the lower end of the internal conical surface nozzle body. By adopting uniform distribution of an internal conical surface structure, and using a thinning effect of airflow on the internal conical surface to the spinning medium, a high-speed stretching role of airflow to jet flow, and a keeping function of hot airflow residual heat to environment temperature, the problems of fiber refining and high-efficiency spinning are well solved, and a plurality of nozzles can be used as a basis assembly of the melt electrostatic spinning industrialization through different forms of expansion combinations.
