Abstract: A fluidic dispensing device includes a housing having an exterior wall and a chamber. The exterior wall has a first opening. The chamber has an interior space and has a port coupled in fluid communication with the first opening. A stir bar is located in the chamber. The stir bar has a rotational axis. A guide portion is located in the chamber. The guide portion includes a confining member having a guide opening that defines an interior radial confining surface that engages the stir bar, wherein the guide opening facilitates a radial movement of the stir bar in a direction substantially perpendicular to the rotational axis.

Abstract: A fluid ejection head having a fluid supply body having a nosepiece with at least one fluid supply port. A pedestal extends outwards from the exterior of the nosepiece near the fluid supply port. A semiconductor chip mounting surface is formed on the pedestal. A flexible circuit bonding surface, formed by a plurality of ribs, also extends outwards from the exterior surface of the nosepiece adjacent the perimeter of the pedestal. A damage reducing structure for reducing damage to a semiconductor chip mounted on the pedestal is located between the pedestal and the flexible circuit bonding surface. Similarly, a damage reducing structure is located between each adjacent pair of the plurality of ribs. In each case, the damage reducing structure may be void space that isolates and reduces damage caused by shock waves traveling through the fluid supply body to the chip mounting surface and the chip mounted thereon.

Abstract: A fluidic dispensing device for dispensing a fluid has a body having a chamber with a perimetrical end surface. An ejection chip is attached to the body in fluid communication with the chamber. A diaphragm has a dome portion and a perimeter sealing surface. The perimeter sealing surface of the diaphragm is in sealing engagement with the perimetrical end surface of the chamber to define a fluid reservoir that contains the fluid. The diaphragm has a deflection axis that is substantially perpendicular to a plane of the perimeter sealing surface. The diaphragm has a cross-section profile that controls a deflection of the dome portion to collapse along the deflection axis in a direction that is at least one of toward or away from a plane of the perimeter sealing surface as the fluid is depleted from the fluid reservoir.

Abstract: A fluidic dispensing device includes a housing, and a fluid channel in the housing. The fluid channel has a channel inlet, a channel outlet, and a passage between the channel inlet and the channel outlet. The channel inlet is in fluid communication with an inlet port of a chamber. The channel outlet is in fluid communication with an outlet port of the chamber. The passage is in fluid communication with an opening in an exterior wall. The fluid channel has a first corner structure in the passage. A stir bar is located in the chamber to generate a fluid flow through the fluid channel when rotated. A first flow director member is positioned adjacent the channel inlet. The flow director member has a first surface structure that directs a portion of the fluid flow toward the first corner structure in the passage.

Abstract: A fluidic dispensing device for dispensing a fluid has a body having a chamber with a perimetrical end surface. The body has a stepped arrangement that includes a channel having a first inner side wall that defines a recessed path around the perimetrical end surface. A diaphragm has a dome portion, a perimetrical positioning rim, and a sealing surface. The channel of the body is sized and shaped to receive the perimetrical positioning rim of the diaphragm. The first inner side wall of the channel of the body engages a perimeter of the perimetrical positioning rim of the diaphragm to position the sealing surface of the diaphragm for sealing engagement with the perimetrical end surface of the chamber to define a fluid reservoir.

Abstract: A fluidic dispensing device includes a housing having an exterior wall and a fluid reservoir. The exterior wall has a chip mounting surface defining a first plane and has a first opening. The fluid reservoir is in fluid communication with the first opening. An ejection chip is mounted to the chip mounting surface. The ejection chip is in fluid communication with the first opening. The ejection chip has a plurality of ejection nozzles oriented such that a fluid ejection direction is substantially orthogonal to the first plane. A stir bar is moveably confined within the fluid reservoir. The stir bar has a plurality of paddles and a rotational axis, with each of the plurality of paddles having a free end tip that intermittently faces toward the first opening that is in fluid communication with the ejection chip as the stir bar is rotated about the rotational axis.
