Liquid material discharge mechanism and liquid material discharge device

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 and
• a 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, and
• an 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.
