A cleaning device is provided that includes a handle, a cleaning implement, a flexible neck, and a collar. The cleaning implement depends from one end the handle. The flexible neck is positioned to allow flexion of the handle. The collar moves with respect to the flexible neck between a first position where movement of the flexible neck is unrestricted by the collar and a second position where movement of the flexible neck is restricted by the collar.

A personal hygiene device has a handle and a treatment head pivotably connected with the handle. Applying a treatment force against the treatment head causes a pivoting of the treatment head relative to the handle. A sensor, such as, e.g., a Hall sensor, fixedly secured with respect to one of the handle and the treatment head, measures a measurement variable. A sensor cooperation unit defines or influences the measurement variable in dependence on the relative position of the sensor and the sensor cooperation unit, such e.g., as a sensor permanent magnet, fixedly secured relative to one of the handle and the treatment head. A spring unit defines a rest position of the treatment head when no treatment force is applied. The spring unit has a first spring constant in the treatment direction and a second spring constant in a lateral direction, the second spring constant being at least about two times higher than the first spring constant.

The present invention is concerned with an electric utility brush having a flexible drive shaft, and in particular an electric toothbrush having a substantially spherical head mounted on the flexible drive shaft and which can be driven rotationally in at least two different orientations in order to provide comprehensive brushing capabilities.

A toothbrush includes a brush head linkage (100), a connecting mechanism (200) and a toothbrush handle (300); the connecting mechanism (200) includes a first connector (210), a second connector (220) and an elastic structural element (230) connected to the second connector (220); the first connector (100) is rotatably connected to the second connector (220), and the axis of rotation extends in a front-rear direction; and the elastic structural element (230) includes at least one return torsion spring (231), the return torsion spring (231) includes a helix spring (2311) in the form of a cylinder with an opening of the cylinder oriented in a direction parallel to an extension direction of an oscillating reference line, the helix spring is in stop fit with the second connector (220) in a direction perpendicular to the oscillating reference line, and the return torsion spring further includes a first torsion bar (2311) and a second torsion bar (2312) respectively connected to a front end and a rear end of the helix spring (2311). The toothbrush according to the present disclosure can protect teeth.

An oral cleaning device comprises a body which carries a set of projections. An actuator device is associated with one or more of the projections in the form of an electroactive polymer structure for adjusting a position of the associated one or more projections. This enables dynamic control of the cleaning function.

Mascara according to the present invention includes: a handle; a brush rod extended from one side of the handle; and a tip member provided at one end of the brush rod, in which the tip member includes a base part shaped like a pillar, and a plurality of protruding parts protruding from an outer circumferential surface of the base part, and the base part and the protruding part are made of a metal material.

A toothbrush protective of tissues may include an elongated toothbrush handle assembly including an elongated biasing member including a bridge hinge axis perpendicular to a major longitudinal axis and configured for flexing movement about a bridge hinge axis in common with flexing movement of a major transition member about a transition member hinge axis proximate the bridge hinge axis, a major handle member which may include a handle member first connection configured to receive a biasing member first end and a handle member second connection configured to receive a transition member first end, and a major head member which may include a head member first connection configured to receive a biasing member second end and a head member second connection configured to receive a transition member second end.

A configurable personal washing device includes a central portion, a handle portion, a washing end portion, a first rotating joint connecting the central portion to the handle portion, and a second rotating joint connecting the central portion to the washing end portion. The first rotating joint and the second rotating joint are configured to permit selection between a first, curved state, a second partially extended state, and a third, fully extended state.
