The present disclosure is directed to systems and methods for electronic control of an operating level of an oral irrigator, particularly when flow from the oral irrigator is paused. Methods for controlling an operational level include: determining an operational level of the oral irrigator, including whether the operational level is a standby mode; receiving sensor data from one or more sensors; determining whether a key sensor indicator is above, below, or at a threshold. If the key sensor indicator is above a threshold, the operational level is changed to standby mode. If the key sensor indicator is at or below the threshold, the operational level remains at the current level. If the key sensor indicator is below the threshold, and the current operational level is the standby mode, the operational level is changed to the operational level set before entering standby mode.

A personal care device, such as an irrigator, which may be an oral irrigator, a nasal irrigator, or similar. The personal care device may be used to cleanse a user's oral cavity, such as by injecting a liquid such as water into the spaces between a user's teeth. The device may include two housings that are slidably coupled together, with the upper housing containing the electronic components and the lower housing containing a reservoir for holding water or other liquids that are to be dispensed. During use, the lower housing may slide upwardly as the liquid is dispensed due to the formation of a vacuum inside of the cavity of the lower housing. Thus, an air flow passageway may be formed that extends from the ambient into the cavity of the lower housing. The device may also include a cap with a locking closure to prevent accidental opening and spilling.

The present disclosure provides an oral hygiene device member capable of further reducing a burden on a target object in an oral cavity and capable of maintaining a cleaner state while suppressing deterioration in cleaning performance. Oral hygiene device member according to the present disclosure comprises handle having flow path through which liquid is allowed to pass. Oral hygiene device member comprises head comprising: head body connected to one end side of handle; and head material held by head body. Head material comprises a cleaning part. The cleaning part is exposed from the head body in a state of being held by the head body. The cleaning part is formed of fibers that clean a target object in an oral cavity. Liquid supply path is formed in the head. The liquid supply path communicates with the flow path and supplies liquid to the cleaning part.

A toothbrush system configured to be coupled to an external suction source. The toothbrush system includes a shaft with a main body with a first end and a second end, and a bristle array and a suction port arranged at the second end. The bristle array and the suction port both extend away from the shaft so that an opening of the suction port is proximal to a distal end of the bristle array. The shaft also includes a stem arranged at the first end. The stem includes a passageway that extends through the main body to provide a fluid connection to the suction port, and is configured to be coupled to the external suction source. Also, the handle is removably coupled to the shaft and includes a drive system operably coupled to the bristle array to actuate motion of the bristle array.

An oral irrigator system having an ergonomic casing with a pliable nozzle assembly, and coupled to a detachable and refillable fluid reservoir. The ergonomic casing contains a power source and a pump mechanism. The detachable nozzle head delivers a pulsating jet of fluid with adjustable speed into the oropharyngeal cavity. When the system is turned on, the rechargeable battery activates the diaphragm pump to draw fluid from the reservoir using a fluid pipe and delivers the fluid to the tip of the nozzle head.
