Technical Field

[0001] This utility model relates to the field of electrospinning technology, and in particular to an electrospinning device. Background Technology

[0002] As is well known, electrospinning is a highly efficient technology for preparing continuous nanofibers. The electrospinning process involves forming a Taylor cone and jet from the spinning solution using an electrostatic field. Under the combined action of charge repulsion, gravity, surface tension, and electric field, the jet is stretched and refined, ultimately forming nanofibers that are deposited on the receiving substrate. With the rapid development of electrospinning technology, the market demand for different types of nanofibers is increasing.

[0003] Existing needle-type electrospinning devices require the ejection of fibers through needles during use. After prolonged use, the needles are prone to clogging due to solution solidification, affecting the spinning efficiency. Therefore, the needles need to be disassembled and cleaned. However, existing devices do not provide ideal quick disassembly of the needles. Therefore, there is a need to provide an electrospinning device to solve the above problems. Utility Model Content
