FLOW-THROUGH EJECTION SYSTEM INCLUDING COMPLIANT MEMBRANE TRANSDUCER |
摘要 |
A liquid dispenser includes a substrate. A first portion of the substrate defines a liquid dispensing channel including an outlet opening. A second portion of the substrate defines a liquid supply channel and a liquid return channel. A liquid supply provides a continuous flow of liquid from the liquid supply through the liquid supply channel through the liquid dispensing channel through the liquid return channel and back to the liquid supply. A diverter member, positioned on a wall of the liquid dispensing channel that includes the outlet opening, is selectively actuatable to divert a portion of the liquid flowing through the liquid dispensing channel through outlet opening of the liquid dispensing channel. The diverter member includes a MEMS transducing member. A first portion of the MEMS transducing member is anchored to the wall of the liquid dispensing channel that includes the outlet opening. A second portion of the MEMS transducing member extends into a portion of the liquid dispensing channel that is adjacent to the outlet opening and is free to move relative to the outlet opening. A compliant membrane is positioned in contact with the MEMS transducing member. A first portion of the compliant membrane separates the MEMS transducing member from the continuous flow of liquid through the liquid dispensing channel. A second portion of the compliant membrane is anchored to the wall of the liquid dispensing channel that includes the outlet opening. |
