Abstract
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.
