Abstract

A nozzle member (14) of a personal care device (10) comprising: a nozzle head (16) positioned at an end of the nozzle member; and an orifice (40) formed in a surface (30) of the nozzle head, wherein the orifice comprises at least one liquid jet orifice (42) configured to allow the liquid and / or air to exit the nozzle head in the form of a jet, and at least one liquid sheet orifice (40a-d) configured to allow the liquid and / or air to exit the nozzle head in the form of a sheet.

Description

technical field [0001] The present disclosure generally relates to personal care devices and methods using liquid sheet cleaning action. Background technique [0002] Proper personal hygiene can help improve health and reduce illness, infection and other health problems. For example, proper dental cleaning can help promote long-term dental health. One aspect of cleaning your teeth properly is using an oral irrigator to remove plaque to clean your gums and teeth. Oral irrigators are especially important in areas that are not easily reached by a toothbrush, such as between the teeth and along the gumline. The cleaning power of water pressure provided by oral irrigators or other personal care cleaning devices can be problematic because increasing the drive pressure reduces the comfort of the water jet. If users feel unwell, they may stop using the product; alternatively, if the water pressure is insufficient, adequate cleaning will not be provided. [0003] Personal care cl...
