Detailed description of the invention
The electrostatic spinning nozzle of face of cylinder triangle center symmetric array as shown in Figure 1 to Figure 3, including body 1, body
1 has the face of cylinder being positioned at top and is provided with at least three group export structures, and described export structure is used for collecting and spraying
Spinning liquid.
Often group export structure is by three connecting holes being opened on the face of cylinder and the pin type being connected on connecting hole
Nozzle 2 forms, and the connecting hole in accompanying drawing overlaps with needle nozzle 2, and therefore connecting hole does not the most indicate.These three
The triangle track of line of connecting hole, namely these three connecting hole is on the end points of a triangle, wherein has two companies
The line section connecing hole is parallel with the axis on the face of cylinder, in other words, and wherein of the triangle being made up of these three connecting hole
While be parallel to the axis on the face of cylinder.
In embodiment, later group export structure relative to previous group export structure at the axis direction Shang Cheng center on the face of cylinder
Symmetry is also spaced a distance, and thus, on the axis direction on the face of cylinder, each group export structure constitutes multiple triangle center
The arrangement form of symmetric array.It addition, above-mentioned multiple trianglees are parallel to the limit of face of cylinder axis the most point-blank.
The symmetrical centre of adjacent two trianglees is also on this straight line.

On the end points of dihedral, namely by track triangle after three subpoint lines.From above-mentioned also, each export structure
Connecting hole projection in the horizontal plane constitute the linear array figure of centrosymmetry triangle at multiple interval.Concrete next
Saying, with reference to Fig. 3, triangle the most adjacent on above-mentioned horizontal plane is centrosymmetric knot in the horizontal plane relative to point 33
Structure, but adjacent two triangular compartments one distance, d, this spacing being two groups of export structures spaced apart.
Above-mentioned needle nozzle 2 is needle point structure away from the end of connecting hole, and this kind of needle nozzle 2 is commonly used in the art
Nozzle structure, is not explained in detail at this.The needle nozzle 2 often organizing export structure is all contour, and different group output
Each needle nozzle 2 of structure is also contour, namely all of needle nozzle 2 is both with respect to contour for the face of cylinder.These pins
Formula nozzle 2 extends along the normal direction on the face of cylinder.
Above-mentioned body 1 can be complete cylindrical structure thus its surface is the face of cylinder, it is also possible to be only one
Part has the structure on the face of cylinder.
Have above-mentioned connecting hole, the electrostatic spinning nozzle of needle nozzle track can greatly reduce in each needle nozzle electric field
Influence each other so that the most advanced and sophisticated electric field of each needle nozzle is more uniform.
In the triangular trajectory that above-mentioned often group three connecting holes of export structure are constituted, it is parallel to the limit of face of cylinder axis

Preferably, in same group of export structure, the projection in the horizontal plane of each connecting hole is respectively at the end points of equilateral triangle
On.The projection of i.e. three connecting holes constitutes the track of an equilateral triangle.This arrangement is more beneficial for ensureing most advanced and sophisticated electric field
Uniform.
It is further preferred that the spacing of adjacent sets export structure is actually adjacent equilateral triangle on horizontal plane
Distance.As shown in Figure 3, the spacing of adjacent sets export structure is actual is spacing d between subpoint 31 and subpoint 32, and should
Spacing d is the most equal with the length of side of equilateral triangle, and this arrangement is more beneficial for ensureing the uniform of most advanced and sophisticated electric field.
The spinning process of above-described embodiment is as follows:
As shown in Figure 4, being evenly applied on each needle nozzle 2 by outside coating unit by spinning liquid, body 1 is relative to receipts
Acquisition means 4 is fixed, and needle nozzle 2 is towards collection device 4, and spinning liquid is in needle nozzle 2, collection device 4 institute
Producing induced jet under the induction electric field formed, induced jet is induced to collection device 4 and forms fiber.
In other embodiments of electrostatic spinning nozzle, what needle nozzle 2 can have hollow goes out sap cavity, and this goes out sap cavity and passes through
Before and after logical needle nozzle 2, having inlet on body 1 surface, body 1 is internal has solution channel, goes out sap cavity by correspondence
Connecting hole, solution channel connection inlet.Now, connecting hole may be considered a spray orifice.
The spinning process using the preferred embodiment is as follows:
As shown in Figure 4, body 1 is fixed relative to collection device 4, and needle nozzle 2 is towards collection device 4, will
Spinning liquid injects in sap cavity by solution channel and arrives needle nozzle 2 top, and spinning liquid is at needle nozzle 2, collection device 4
Producing induced jet under the induction electric field formed, induced jet is induced to collection device 4 and forms fiber.This spinning process
Can continue with spun structure and carry out spinning incessantly.
