  • Patent number: 10124593
    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.

  • Patent number: 10059113
    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.

  • Publication number: 20180154385
    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.
