A toothbrush tip includes a brush head, a plurality of bristle tufts extending from the brush head, a water jet nozzle extending from the brush head, and a cover panel arranged on a rear of the toothbrush tip opposite the bristle tufts.

A drive train assembly (200) for a personal care device (10), comprising a torsion spring (210) suspended between a first end mount (220) and a second end mount (230), the torsion spring comprising a first end mounted to the first end mount and a second end mounted to the second end mount, wherein the first and second ends of the torsion spring each comprises a cross flexure spring hinge (250, 260).

The present disclosure includes embodiments directed to an oral cleansing device. The device may include a handle housing and a hose connector. The handle housing may include an end defining an aperture and the hose connector may be releasably coupled to the end. The hose connector may include a hose fluidly coupled to a reservoir and a body defining an inlet and an outlet. The hose may be coupled to the body and be in fluid communication with the inlet. The hose connector may include a collar coupled to the body and positioned around the hose at the inlet. In a first configuration, the outlet of the body may be positioned within the aperture of the handle housing and in a second configuration the outlet of the body may be separated from the handle housing.

An electric cylindrical-rotation and in-line sweeping toothbrush is disclosed. The electric cylindrical-rotation and in-line sweeping toothbrush having a rotating shaft, a handle and a motor comprising: a first portion having perpendicular bristles to the rotation axis of the rotating shaft that includes at least one rotating head with bristles thereon; wherein the perpendicular bristles located on the rotating shaft and the rotation axis in rotation of the rotating shaft sweeps the whole length of the bristles section against the section of teeth in the same manner, and the toothbrush provides consistent sweeping from the gum towards the tip of the teeth in every part of the whole set of teeth.

A toothbrush tip includes a brush head, a plurality of bristle tufts extending from the brush head, a water jet nozzle extending from the brush head, and a cover panel arranged on a rear of the toothbrush tip opposite the bristle tufts.

Disclosed are an acoustic wave type electric cleaning and care tool and a pressure warning device for same. Upper and lower drive shaft bearings are fixed on a drive shaft. The upper bearing is fixed in left and right brackets by a fixed surface and is stationary. The lower bearing is fixed in the brackets by a upper fixed surface and perform a relative movement such that the lower bearing is separated from or contact with the upper fixed surface. The alarm device comprises a lever, a light-emitting element and a photosensitive element. The lever is provided with a shielding surface and/or a light-shielding protrusion. Light energy is changed by the change of gap between the shielding surface and/or the light-shielding protrusion and the photosensitive element. The change in electrical performance parameters of the photosensitive element is detected to acquire a load pressure on a cleaning element and realize pressure alarm.

An oral irrigator including a base and a handle. The base includes a fluid reservoir, a pump in fluid communication with the fluid reservoir, and a base wireless communication component in electrical communication with the pump. The handle is in fluid communication with the pump. The handle includes a handle wireless communication component and one or more control buttons in communication with the handle wireless communication component. The handle wireless communication component transmits control signals from the one or more control buttons to the base wireless communication component to adjust an operating parameter of the pump.

The invention relates to an electric toothbrush provided with longitudinal, also called axial, oscillating movement that occurs at the active end of the bristle plumes, or nylon filaments, without the end or tip of the brush causing potentially traumatic blows, which represent an undesired risk, as still occurs according to the existing prior art.

A method of attaching a brush head to an oral cleansing device is provided. The method may include inserting a drive shaft of the oral cleansing device into a shaft of the brush head. The method may include causing, in response to inserting the drive shaft into the shaft of the brush head, a cantilevered beam inside the shaft to bend outward, creating a reactionary force that presses against the drive shaft.
