Electrospun head and electrospinning apparatus

摘要

Problem to be solved: to provide an electrospun head capable of appropriately jetting raw material liquid from the ejection port to the collector and substrate.The electrospinning head 2 comprises a head body 11 and a nozzle 12.A storage cavity 15 is formed inside the head body, and the nozzle protrudes from the outer peripheral surface of the head body.In the nozzle, a flow path 17 communicating with the storage cavity is formed inside, and a discharge opening 18 is formed at the protruding end.In the nozzle, a first extending portion 21 forms a connection portion to the head body, and the second extended portion 22 projects from the first extended portion and forms a protruding end.As compared with the first volume of the portion except the flow passage of the first extended portion, the second volume except the flow passage of the second extended portion is small, and in the second extended portion, the dimension along the protruding direction is smaller than the first extended portion.Diagram
