An oral care implement including a handle and an oral care refill head. The handle has a gripping portion, an engagement component coupled to a distal end of the gripping portion, and a stem. The engagement component includes a plate portion and a first engagement feature. The stem extends through an opening in the engagement component and protrudes from the plate portion. The oral care refill head includes an oral care treatment portion and a sleeve portion. The sleeve portion has an inner surface that defines a sleeve cavity having a cavity axis and a second engagement feature. When the oral care refill head is detachably coupled to the handle, the first and second engagement features mate with one another to at least one of: (1) position the oral care refill head and the handle in an operational alignment; and (2) lock the oral care refill head to the handle.

A toothbrush (10) includes a brushhead (18), a first force sensor (30A) for measuring a first force exerted by the brushhead at a first angle relative to a tooth and a second force sensor (30B) for measuring a second force exerted by the brushhead at a second angle relative to the tooth, the second angle being different than the first angle, and a processing unit (26). The processing unit is structured to: (i) receive first information indicative of the first force as measured by the first force sensor, (ii) receive second information indicative of the second force as measured by the second force sensor, and (iii) determine information regarding a current brushing angle of the brushhead based on the first information and the second information.

Described herein is an electronic dual-head teeth cleaning appliance that facilitates simultaneous front and rear surface cleaning of individual teeth. The teeth cleaning appliance is rechargeable, portable, lightweight, and electronic. In particular, the appliance is equipped with an ergonomic axially rotating handle, speed settings, and may have rubber bristles on the brush heads for massaging the gums during teeth cleaning. The bristles may have side-to-side or rotational action.

Cleaning devices are provided that have a surface with areas that provide different cleaning states. The areas of different cleaning states are connected to one another by a deflection member that provides tactile and/or audible feedback to the user when transitioning between the different cleaning states.

A personal care device (10) configured to generate a feedback signal in response to excessive pressure applied by a user includes: a body portion (12) comprising a first interacting portion (40); a shaft (24) comprising a second interacting portion (42), wherein the shaft and the second interacting portion are moveable, in response to a force applied by the user, from a first position in which the first interacting portion does not physically interact with the second interacting portion, to a second position in which the first interacting portion physically interacts with the second interacting portion; and a sensor (70) configured to detect the physical interaction between the first interacting portion and the second interacting portion, and further configured to activate a feedback signal, in response to the detection of the physical interaction, to the user that excessive pressure is being applied.

A pet brush system that includes a brush with a set of vibrating bristles at an application end of the brush. A handle extends from the set of vibrating bristles with a power connection at a distal end of the handle. A battery is included within the handle for power. The system further includes a power cord adapted to connect to the power connection to supply power to the brush.
