Liquid material discharge mechanism and liquid material discharge device

摘要

The present invention provides a discharge mechanism has a drive unit that moves a rod reciprocally, and a discharge unit including a liquid chamber allowing the rod to pass therein and a valve seat communicated with a nozzle, the nozzle discharging a liquid mixed with solid particles with an operation of moving the valve seat and a tip of the rod relatively away from each other. The discharge unit includes an inflow path through which the liquid mixed with the solid particles flows into the liquid chamber, and an outflow path through which the liquid mixed with the solid particles in the liquid chamber flows out. The inflow path and the outflow path are connected in a V-shape, the liquid chamber is disposed in a valley portion of the V-shape, and the valve seat is disposed at a lower end of the V-shape.

1. A discharge mechanism for a liquid mixed with solid particles comprising:
a rod, a drive unit that moves a rod reciprocally, and a discharge unit comprising
a liquid chamber allowing the rod to pass therein anda valve seat communicated with a nozzle, the nozzle discharging therefrom a liquid mixed with solid particles with an operation of moving the valve seat and a tip of the rod relatively away from each other,an inflow path through which the liquid mixed with the solid particles flows into the liquid chamber, andan outflow path through which the liquid mixed with the solid particles in the liquid chamber flows out, wherein the liquid is discharged continuously in a linear form, or is discharged to fly from the nozzle in the form of a droplet, wherein the inflow path and the outflow path are connected in a V-shape near the valve seat, the liquid chamber being disposed in a valley portion of the V-shape, wherein the valve seat is disposed at a lower end of the liquid chamber corresponding to a lower end of the V-shape, the upper surface of the valve seat having a concave of a conical shape, and wherein the concave has a larger area than a contact area of the tip of the rod.
