Title:
NOZZLE BLOCK PROVIDED WITH NOZZLE CLOGGING PREVENTION MEANS, AND ELECTROSPINNING DEVICE INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2021/112394
Kind Code:
A1
Abstract:
The present invention relates to a nozzle block which is applied to an electrospinning device and comprises: a spinning nozzle provided with a hollow spinning needle for ejecting a spinning solution to the outside; at least one piercing means having a smaller diameter than the spinning needle and coaxially arranged inside the spinning needle; and a reciprocating mechanism for reciprocating the piercing means and the spinning needle relative to each other. Accordingly, it is possible to prevent the solution from solidifying at the tip of the spinning nozzle or the spinning nozzle from becoming clogged by external pollutants, even when an electrospinning process is temporarily paused in the middle of the process.
