Abstract
A fluidic dispensing device includes a housing having an exterior wall and a chamber. The exterior wall has a chip mounting surface defining a first plane and having an opening. The chamber has an interior space. The chamber has an inlet port and an outlet port, the inlet port being separated a distance from the outlet port. An ejection chip is mounted to the chip mounting surface of the exterior wall. The ejection chip is in fluid communication with the opening. A fluid channel is formed in the housing that is in fluid communication with each of the opening, the inlet port, and the outlet port.
Claims19
A fluidic dispensing device, comprising:
- a housing having an exterior wall and a chamber, the exterior wall having a chip mounting surface defining a first plane and having an opening, the chamber having an interior space, the chamber having an inlet port and an outlet port, the inlet port being separated a distance from the outlet port;
- an ejection chip mounted to the chip mounting surface of the exterior wall, the ejection chip being in fluid communication with the opening;
- and
- a fluid channel formed in the housing that is in fluid communication with each of the opening, the inlet port, and the outlet port, wherein the fluid channel has a wall positioned between the inlet port and the outlet port, the wall having a wall portion positioned to face the opening of the exterior wall and the fluid ejection chip, and wherein a distance between the wall portion and the fluid ejection chip is narrowest at a mid-point of the longitudinal extent of the fluid ejection chip.
A fluidic dispensing device, comprising:
- a housing having an exterior wall and a chamber, the exterior wall having a chip mounting surface defining a first plane and having an opening, the chamber having an interior space, the chamber having an inlet port and an outlet port, the inlet port being separated a distance from the outlet port;
- an ejection chip mounted to the chip mounting surface of the exterior wall, the ejection chip being in fluid communication with the opening;
- and
- a fluid channel formed in the housing, the fluid channel couples the inlet port in fluid communication with the outlet port, the fluid channel being in fluid communication with the opening of the exterior wall,
- wherein each of the inlet port and the outlet port of the chamber has a beveled ramp structure arranged such that each of the inlet port and the outlet port converges in a direction toward the fluid channel.
A fluidic dispensing device, comprising:
- a housing having an exterior wall and a chamber, the exterior wall having a chip mounting surface defining a first plane and having an opening, the chamber having an interior space, the chamber having an inlet port and an outlet port, the inlet port being separated a distance from the outlet port;
- an ejection chip mounted to the chip mounting surface of the exterior wall, the ejection chip being in fluid communication with the opening;
- a fluid channel formed in the housing and being in fluid communication with the opening of the exterior wall, the fluid channel having a U-shape having a channel inlet, a channel outlet, and a convexly arcuate wall extending between the channel inlet and the channel outlet, the channel inlet being in fluid communication with the inlet port of the chamber and the channel outlet being in fluid communication with the outlet port of the chamber, the convexly arcuate wall positioned to face the ejection chip;
- and
- the inlet port of the chamber having a beveled inlet ramp arranged such that the inlet port converges in a direction toward the channel inlet of the fluid channel, and the outlet port of the chamber having a beveled outlet ramp arranged such that the outlet port diverges in a direction away from the channel outlet of the fluid channel.
