Electrostatic spinning sprinkler in trapezoid wave array and electrostatic spinning device

Abstract

The invention discloses an electrostatic spinning sprinkler in a trapezoid wave array and an electrostatic spinning device. The sprinkler comprises a sprinkler body, wherein the sprinkler body is provided with one output plane and at least three output structures, each output structure comprises four spraying holes formed in the output plane and needle-type spray nozzles connected at the spraying holes, the four spraying holes of each output structure are located on vertexes of a trapezoid respectively, the later output structure and the former output structure are in central symmetry, every two adjacent output structures share one spraying hole and take the spraying hole as the symmetry center of the two output structures, and the needle-type spray nozzles are at the same height. By comparison with spray nozzles arranged in linear array tracks in the prior art, electric fields of the spray nozzles of the electrostatic spinning sprinkler are seldom mutually influenced, and the intensity of the electric fields of the spray nozzles is relatively high and has relatively small difference. The electrostatic spinning sprinkler and the electrostatic spinning device can be used for electrostatic spinning.

Description

technical field [0001] The invention relates to the field of electrospinning, in particular to an electrospinning nozzle and an electrospinning device of a trapezoidal wave array. Background technique [0002] The invention patent with the application number 200910031948.2 discloses an array multi-nozzle electrospinning equipment, which uses multiple nozzles arranged in a linear rectangular array on the plane for spinning, which can realize mass production of electrospun fiber membrane materials. [0003] However, after a long period of use, technicians found that when the nozzles are arranged in a rectangular array, the electric fields at the tips of the nozzles will affect and interfere with each other, making the difference in the electric fields between different nozzles large and resulting in uneven spinning; even the electric field of some nozzles Not enough to reach the critical spinning value. Contents of the invention [0004] In order to solve the above problems...
