摘要:
The spray assembly for a droplet spray teeth cleaning system includes a guidance member at the end thereof. The spray assembly includes a nozzle through which a spray of liquid is directed to the teeth for cleaning. The guidance member is configured and mounted relative to the nozzle to provide a selected standoff distance between the nozzle and the teeth and includes a portion which is configured to fit in the interproximal space between adjacent teeth and gums, or against the frontal portions of the teeth, so that the user knows the location of the spray relative to the teeth.

The spray assembly for a droplet spray teeth cleaning system includes a guidance member (40, 56, 80, 86) at the end thereof. The spray assembly includes a nozzle (24) through which a spray of liquid is directed to the teeth for cleaning. The guidance member is configured and mounted relative to the nozzle to provide a selected standoff distance between the nozzle and the teeth and includes a portion which is configured to fit in the interproximal space between adjacent teeth and gums, or against the frontal portions of the teeth, so that the user knows the location of the spray relative to the teeth.

The personal care appliance drive system includes a pair of linear actuators capable of operating both in an opposing phase mode or in a parallel (in-phase) mode. The system includes a motion converter assembly which converts the opposing phase action of the two linear actuators into a rotational action of an output drive shaft and converts in-phase action to a translation motion of the output shaft or to drive another function of the appliance, such as a pump. The motion converter, operating simultaneously in an opposing phase mode and in-phase modes, produces a complex motion of the workpiece.

A workpiece system with a reciprocating motion which includes a motor assembly for producing an output drive signal with a periodic force pulse. The drive signal is coupled to a driven member assembly through a magnetic arrangement, wherein the driven member assembly has a workpiece mounted thereon with a return spring assembly. The driven member assembly has a resonant mechanical frequency. As the RPM of the motor increases from zero following startup, the drive signal frequency increases to the point very near resonance, where the energy from the drive signal is transferred into the reciprocating motion of the driven assembly, producing an effective amplitude of workpiece motion.
