A vibrating toothbrush and an eccentric shaft are proposed. The vibrating toothbrush includes a head in which bristles are planted, and a handle from which a head coupler protrudes, the head being detachably coupled to the head coupler. The toothbrush includes an electric motor accommodated in the handle to generate rotating force; and an eccentric shaft rotatably connected to the electric motor, at least a portion thereof being eccentric to generate vibration and thereby transmit vibration to the head coupler. The eccentric shaft includes a motor fixing part connected to the electric motor; an eccentric weight configured to be offset from a rotation center of the electric motor; and a rotating shaft formed of a metal material, and connecting the motor fixing part and the eccentric weight.

The vibrating soap or lotion dispensing bath brush comprises a brush body, a bristle attachment, and a soap holder. The bath brush may be adapted to brush skin of a user with a plurality of bristles located on the bristle attachment. As a non-limiting example, the bath brush may ease the task of washing hard to reach areas, such as the user's back. The bath brush may dispense a grooming product from a product dispenser located within the brush body. As a non-limiting example, the grooming product may be liquid soap or a lotion. A bar of soap may be removably coupled to the soap holder. The bath brush may be adapted to rub the bar of soap on the skin.

An oral care system comprising: a. an electrical motor b. a base assembly comprising: i. an elongated base-assembly main body defining an elongate axis; and/or ii. a battery or a battery compartment optionally including electrical contacts for a battery, the battery and/or the battery compartment being electrically wired to the electrical motor; and c. a head assembly is disclosed herein. Methods and kits are also disclosed.

An electrical appliance for personal care includes a handle with a longitudinal axis, and a plug-on part which can be attached to the handle, wherein a vibration unit having an electric motor and an eccentric element is arranged in the handle, wherein a plug-like coupling structure protrudes from the handle, which plug-like coupling structure forms an interface with a substantially mirror-inverted socket-like coupling structure of the plug-on part, wherein the interface has at least two stages with different circumferential geometry, wherein at least one of the stages has a rotation-preventing device between the handle and the plug-on part, and wherein a stop surface of the handle for the plug-on part extends obliquely with respect to the longitudinal axis of the handle.

This invention relates to a device (1) for performing personal care operations on a subject. The device (1) comprises a handheld base body (3), a driving unit (400) to receive and drive an interchangeable treatment head (2) to perform the personal care operation, a sensor (7) for measuring the amount of current drawn from a motor arrangement (5, 6) while the driving unit (400) is being operated. The device (1) further comprises a control unit (8) operably connected to the sensor (7) and the driving unit (400) and configured to control the driving unit (400). The control unit (8) is configured to identify the individual treatment head (2) fitted on the driving unit (400) by comparing the measured motor current at the predefined measuring time (t1) with at least one predefined current threshold (C).

An electric toothbrush relates to personal care products, oral care products, namely, toothbrushes. The technical result is achieved due to the fact that the electric toothbrush consists of a bottle body containing the cleaning agent, a neck with a bristle attachment, a push dispenser for feeding the cleaning agent, while the bottle body and the neck with the bristle attachment are connected by a fixing device and move in the longitudinal plane relative to each other, wherein the neck housing comprises an insert-type electric actuator tightly fixed therein, a compartment for at least one battery, an insulating cover of the compartment, and a button for activating the toothbrush, wherein the bristle attachment performs a vibration movement, and wherein the spout of the head of the push dispenser does not come into contact with the bristle attachment when in the folded position.

An electrical toothbrush head includes a toothbrush body and an insertion piece that includes a core channel and a sideway slot in which an elastic bar is arranged. The core channel has a contact engagement surface. The elastic bar has a curved section. When the vibration core is inserted into the core channel, the contact engagement surface and the curved section respectively contact and engage with core side surfaces of the vibration core, and the elastic bar is pushed to elastically deform away from the contact engagement surface. When the electrical toothbrush head and the toothbrush handle are combined, the vibration core is clamped between the contact engagement surface and the curved section and the elastic bar deforms outward and the elastic filler block is compressed, such that the elastic filler block and the elastic bar cause the curved section to be in elastic engagement with the vibration core.

The present disclosure provides a brushhead for a power toothbrush detachably, and the power toothbrush. The brushhead configured for a power toothbrush, the brushhead being detachably installed on a handle of the power toothbrush, the brushhead comprising: a brushhead element and an engaging assembly arranged in the brushhead element, wherein the engaging assembly receives a driving shaft therein within and is configured to be driven by the driving shaft to vibrate, and wherein the engaging assembly comprises a main body and an elastic member, the elastic member is a stand-alone element arranged on the main body, and the elastic member abuts against the driving shaft.

Embodiments are described wherein a system for brushing the teeth of a person comprises a master input device; a flexible teeth tray configured to at least partially encapsulate one or more of the teeth in a flexible substrate material, the flexible teeth tray comprising one or more vibratory transducers removably coupled to one or more brushing panels; and a controller operatively coupled to the master input device and the one or more vibratory transducers; wherein subject to an input from the master input device, the controller is configured to cause reciprocating brushing motion of the one or more brushing panels against a surface of the one or more encapsulated teeth, to clean the one or more teeth.

The present disclosure provides a brushhead for a power toothbrush detachably, and the power toothbrush. The brushhead configured for a power toothbrush, the brushhead being detachably installed on a handle of the power toothbrush, the brushhead comprising: a brushhead element and an engaging assembly arranged in the brushhead element, wherein the engaging assembly receives a driving shaft therein within and is configured to be driven by the driving shaft to vibrate, and wherein the engaging assembly comprises a main body and an elastic member, the elastic member is a stand-alone element arranged on the main body, and the elastic member abuts against the driving shaft.
