Embodiment
As shown in Figure 1, a kind of firing pin type droplet ejection device of solenoid actuated, including striker 1, spring 2, upper valve body 3,
Lower valve body 4, nozzle 6, glass micropipette 7, crossbeam 8, electromagnet 9, sliding block 10 and sliding rail 11；
Electromagnet 9 is mounted on upright slide rail 11, its armature block hits crossbeam upwards after electromagnet 9 receives high level
Striker 1 is driven to be lifted up.
As shown in Fig. 2, there are apertures among nozzle 6, self-control glass micropipette 7 is fitted into nozzle 6, nozzle 6 is mounted on
4 bottom of lower valve body, nozzle diameter determine by the characteristic of injection liquid, glass micropipette and nozzle and according to circumstances carries out at any time more
It changes.Rubber washer is lined between nozzle 6 and lower valve body 4 to be used to prevent drop from leaking in course of injection.
As shown in figure 3, striker is divided into two parts up and down, it is intermediate to be separated with a diameter for the iron plate of 18mm.
2 sets of spring are packed into upper valve body in 1 top half of striker, and when striker 1 is lifted up, spring 2 is shunk, Zhi Hou
The slamming down of striker 1 is realized under the action of 1 self gravity of thrust and striker of spring 2.
8 sets of crossbeam are hit on 1 top of striker, is fixed by screw, and electromagnet 9 hits crossbeam upwards, to drive striker
It is pulled upwardly.
As shown in figure 4, there are the apertures that diameter is about 3mm for lower valve body side surface, by the way that injection solution can be added herein,
Lower valve body lower part is equipped with screw thread and is used to install nozzle, and the cavity of lower valve body storage solution has one to be about the small of 1-2mm with nozzle
Hole is used to that the glass needle in nozzle is protected not crashed by striker.
Glass micropipette at nozzle is cut by drawing needle instrument that glass tubule is pulled to as taper according to the bore of required nozzle
Break and the bore of glass needle is hot melt to using heater strip by required caliber size by microscopical observation using forging needle instrument.
