Embodiment Construction

[0029] The present disclosure describes various embodiments of methods and apparatus for automatically adjusting the diameter of a nozzle of a personal care device using a magnetorheological fluid. More generally, applicants have recognized and appreciated that it would be beneficial to provide automatic adjustment to the unique geometry of a user's mouth, thereby increasing cleaning efficiency. Accordingly, the methods and systems described or otherwise contemplated herein provide a new type of adjustable nozzle for personal care appliances. The nozzle comprises: a nozzle housing having a channel through which a flow of liquid and / or air is directed; and a housing orifice at the end of the channel. The nozzle also includes a magneto-rheological fluid housing positioned over at least a portion of the nozzle housing at the housing orifice, and a tip having an adjustable diameter orifice through which the fluid and / or air flow exits. The nozzle also includes one or more magnets...

Abstract

A nozzle (14) for use with a personal care device (10) comprises: (i) a nozzle housing (50 / 52) defining a central passage (54) through which a flow of liquid and / or air is directed and comprising a housing orifice (56) at an end of said central passage; (ii) a magnetorheological fluid housing (58) over at least a portion of the nozzle housing at the housing orifice and comprising a tip having an adjustable diameter orifice (59) through which the fluid and / or air flow exits, where the adjustable orifice is adjustable between at least a first diameter and a second diameter; and (iii) one or more magnets (62) configured to control magnetorheological fluid (60) in the magnetorheological fluid housing to adjust between the at least first and second diameters of the adjustable diameter orifice.

Description

technical field [0001] The present disclosure generally relates to methods and systems for magnetorheological control of nozzle diameter. Background technique [0002] Proper personal hygiene products can help improve health and reduce disease-related problems, infections and other health problems. For example, proper dental cleaning can help promote long-term dental health. One aspect of proper dental cleaning is the use of a flosser to remove plaque to clean the gums and teeth. Flossers are especially important in areas where toothbrushes do not have easy access, such as between teeth and at the gingival margins. The cleaning power of fluid pressure provided by flossers or other personal care cleaning devices can be problematic because increasing the actuation pressure reduces the comfort of the fluid jet. If the user experience is uncomfortable, they may stop using the product; alternatively, if the fluid pressure is insufficient, it will not provide adequate cleaning....
