The technical solution of the utility model is：A kind of needle-free jet device of electrospinning device, which is characterized in that including
Emission electrode and liquid pool body are equipped with inlet opening in one end of liquid pool body and are packed into inlet tube, and the outer end of the inlet tube and feed liquor are total
Pipe connection；It is equipped with V-shaped groove in the upper surface of the liquid pool body, has the rectangular channel for passing through emission electrode in the bottom of the V-shaped groove,
The upper surface of the V-shaped groove is equipped with liquid pool lid, is the mutually matched trapezoid boss of V-shaped groove with the liquid pool body below the liquid pool lid.
The utility model has the advantages that：
1) electrostatic spinning emission electrode is formed using multiply finer wire twisting, can be improved emission electrode and be adapted to different solutions
Versatility substantially increases ejection efficiency and product uniformity consistency.(Fig. 4 by taking the multiply twisting steel wire of structure 1 × 7 as an example
It is shown), unit weight reduces 22% than only stock steel wire, and steel wire surface product increases 2.3 times, and electrostatic spinning emission effciency is
The 178% of only stock steel wire.
2) liquid pool body uses the nonmetallic manufacture of corrosion-resistant nonhazardous, and liquid pool brush liquid head uses nonmetallic and stainless steel
Matter manufacture, can be replaced according to different solutions system, ensure spinning quality.
3) liquid pool body and liquid pool lid are cooperated using 90 ° of v-depressions and boss, are a kind of very typical mechanical structure,
Processability is high, is easy to obtain higher surface accuracy and geometric tolerance, thus guarantee that cooperation is close, it will not be from faying face leakage.
4) emission electrode for crossing and crossing is located at liquid pool bottom, can make full use of solution in pond, until solution in liquid pool
Stop spinneret when using up just now.
5) this liquid pool injection apparatus changes original multiple concatenated connection types of needle-free jet device after improving,
Each needle-free jet device, which becomes, to be connected in parallel.In order to adapt to needs in parallel, liquid pool is eliminated originally towards next liquid pool
Liquid outlet（Referring to Fig. 5 and Fig. 6）.Parallel greatly strengthens the feed flow consistency of each spray head, reduces phegma
Amount, the injection apparatus feed flow for avoiding that original series connection head end is excessively sufficient, and solution regurgitant volume is too big, and tail end injection apparatus supplies
The disadvantage of liquid deficiency, not only increases each needle-free jet device spinning consistency, and solution utilization rate is also from when series connection
35% is increased to 90% or more.
6) liquid pool lid 3 and liquid pool body 2 are compressed using screw 4, make its fitting closely will not leakage, connection type is simply classical
Reliable process is good.
7) inlet tube and return pipe use minor diameter hose, are conducive to medical fluid pump work and greatly reduce in perfusion tube
Medical fluid amount retained, improve medical fluid service efficiency.
8) the used material of single unit system is all common material, convenient for buying and processing；All structures are all simple flat surfaces
Composition is convenient for maintenance, and whole operations is only slack adjuster when working service, saves the operating time.
