Abstract

A semi-free rotating crankshaft actuator (80) for an oral healthcare appliance comprises a chamber (82), a spring loadable plunger (85), and a crank mechanism (88). The crank mechanism (88) comprisesat least a drive pin (90) rotatably driven about a drive axis (96), and a crank shaft (94) semi-freely rotatable about the drive axis, wherein the crank shaft (94) couples to the spring loadable plunger (85) and is partially driven about the drive axis (96) via (i) the drive pin (90) in a first operational mode, (ii) the spring loadable plunger (85) in a second operational mode, and (iii) the drive pin (90) in a third operational mode that comprises at least completing an incomplete actuation of the plunger (84) from an undesired end position to the desired end position in response to the crank shaft (94) pushing the plunger (84) from the undesired end position to the desired end position.

Description

technical field [0001] The present embodiments relate generally to oral health care implements, and more particularly to a semi-free turning crankshaft actuator for pre-compressing and quick release of a spring-loadable plunger for an oral health care implement and method thereof. Background technique [0002] When it comes to oral hygiene, the usual thinking is to simply brush your teeth. However, brushing alone does not do a good job of cleaning the interdental areas of your teeth. For this reason, dentists recommend flossing in addition to brushing. To improve interdental cleaning, there are several devices on the market that can be used at home. One such device (Airfloss TM device) produces a combination of water droplets and air, which is accelerated through a nozzle to achieve high impact velocities. Air is compressed in the cylinder by a piston which is moved forward by a compression spring. [0003] In prior art versions of this device, the motor drives a pinion...
