Described shower nozzle cavity and Spray-nozzle carrier are connected, hollow cone shower nozzle rear portion is through Spray-nozzle carrier front end, hollow cone shower nozzle rear portion and shower nozzle cavity are rotatably assorted, hollow cone shower nozzle rear end is connected with shower nozzle coupling spindle front end, shower nozzle shaft coupling is provided with central through hole, interior pinhead sleeve is sheathed on interior syringe needle rear portion, interior pinhead sleeve and shower nozzle coupling spindle rear end central through hole are rotatably assorted, interior syringe needle is through shower nozzle shaft coupling, interior syringe needle is positioned at hollow cone shower nozzle, travelling gear is located at shower nozzle coupling spindle rear end outer wall, outer syringe needle is located in outer needle holder, outer needle holder and shower nozzle cavity are connected, outer syringe needle is in the face of hollow cone shower nozzle outer wall, electrode and hollow cone shower nozzle touch, motor is arranged on Spray-nozzle carrier, motor output shaft is provided with driven wheel, driven wheel engages with travelling gear, interior syringe needle, outer syringe needle and electrode be external DC high-voltage power supply all.
Described Spray-nozzle carrier front end is provided with through hole, and hollow cone shower nozzle rear portion is arranged in the through hole of Spray-nozzle carrier.
Described hollow cone shower nozzle rear portion is rotatably assorted by bearing and shower nozzle cavity.
Described interior pinhead sleeve and shower nozzle coupling spindle rear end central through hole are also rotatably assorted by bearing.
Described motor is arranged on Spray-nozzle carrier by electric machine support.
Described electrode is the carbon electrode with spring, is arranged in the electrode sleeve of being located at Spray-nozzle carrier bottom with the carbon electrode of spring.
Compared with the prior art, operation principle of the present utility model and beneficial effect are as follows:
When spinning, interior syringe needle (outer syringe needle) is connect to high-voltage DC power supply positive pole, spinning collecting board is connect to high-voltage DC power supply negative pole, solution or melt from interior syringe needle or syringe needle flow to hollow cone shower nozzle, solution is evenly spin-coated on cone surface, under the acting in conjunction due to centrifugal force and adhesion in rotary course, and liquid meeting deformation, and flow to large end circumference from cone shower nozzle small end, after under electrostatic force, form Electrospun.The utility model, owing to having inside and outside two syringe needles, therefore can inject spinning solution by inside and outside syringe needle to the inside and outside wall of hollow cone shower nozzle simultaneously or separately.When use inside and outside syringe needle can spin mixture nanofiber in the time that hollow cone shower nozzle injects solution simultaneously, comprise two kinds of different types of nanofiber products.Outer syringe needle is fixed on Spray-nozzle carrier by outer needle holder, and maintenance is relative static with Spray-nozzle carrier.When the rotation of shower nozzle coupling spindle, it is static that interior syringe needle keeps.Shower nozzle shaft coupling when rotated shower nozzle cavity keeps static.Motor rotation, by gear transmission, drives shower nozzle shaft coupling and the rotation of hollow cone shower nozzle.In the time that hollow cone shower nozzle rotates, the cylinder ledge surface of electrode and hollow cone shower nozzle keeps in touch, and conducts electricity.Owing to can forming a large amount of taylor cone of evenly arranging (being equivalent to traditional needle point shower nozzle circle ring array arranges) therefore on the large end circumference of cone shower nozzle, the utility model can improve electrospinning device productive rate, simultaneously because the electric field action that on circumference, each taylor cone is subject to is almost identical, therefore spin fiber homogeneity high, and can spin a kind of mixture nanofiber spinning nozzle device of the mixture nanofiber that contains two kinds of different materials simultaneously.
