摘要： The present disclosure relates to a nozzle block applied to an electrospinning device, which includes a radiation nozzle having a hollow radiation needle for discharging a spinning solution to the outside; a means of piercing having a diameter smaller than that of the radiation needle, at least one of which is coaxially disposed inside the radiation needle; and a reciprocating mechanism for reciprocating the means of piercing and the radiation needle relative to each other, thereby preventing the solution from being solidified at the tip of the radiation nozzle or the radiation nozzle from being blocked by external contaminants even if the electrospinning process is temporarily interrupted in the middle.
