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 cleaning device having a handle portion and a surface contacting portion, at least one of the handle portion and the surface contacting portion having a pressure indicator, wherein the pressure indicator provides a reversible signal in response to a certain pressure applied to the cleaning device that is within a certain pressure range.

In one embodiment, an oral care system may include a toothbrush comprising a physical property, and a programmable processor configured to receive physical property data indicative of the physical property of the toothbrush. The programmable processor may be further configured to determine, based at least in part upon the received physical property data, a suggested brushing routine for a user and/or an evaluation of a brushing session of a user

An automatic suction cleaning structure is disclosed. The automatic suction cleaning structure is disposed on a cleaner body. The automatic suction cleaning structure comprises a fixing base (1) connected to the cleaner body and a number of brush heads (2) arranged on the fixing base (1). The brush heads (2) are made of silica gel, and are of a hexagon shape and a hollow structure. The number of brush heads (2) are arranged on the fixing base (1) in an array and distributed in a cellular arrangement. By arranging the cellular brush heads (2) of a hollow structure and utilizing a suction force produced by the tightly-attached brush heads (2) during use, dirt on the skin surface is sucked automatically by means of a sucking disc principle in a process of contact with the skin, to allow more thorough cleaning. A cleaner is also provided.

An oral care appliance and a method of controlling pressure in the oral care appliance are disclosed. The pressure inside a mouthpiece of the oral care appliance is controlled by an actuator. The actuator is triggered when a targeted threshold value of an operational characteristic is reached. Automatic control of the pressure in the mouthpiece enhances both cleaning efficiency and user comfort.

A method for operating a vehicle treatment system, in particular a vehicle washing system, includes treating at least one vehicle surface with at least one rotating brush with a brush material at an immersion depth of the brush, and controlling during the treatment of the vehicle surface, the rotating brush based on a setpoint value for the friction of the brush material on the vehicle surface, the immersion depth of the rotating brush on the vehicle surfaces treated therewith being monitored at the setpoint value during the treatment of the vehicle surface in order to determine the state of the brush material. In addition, a vehicle treatment apparatus, a use thereof, and a computer program product are provided.

A method for detecting entanglement of an object with a brush of a surface cleaning device includes collecting sensor readings indicative of an operational status of the brush of the surface cleaning device using at least one sensor, detecting entanglement of an object with the brush when a magnitude of the sensor readings exceeds a predetermined threshold for a predetermined amount of time using a motor controller of the brush, notifying a processor of the surface cleaning device of the detected entanglement using the motor controller, and actuating an action in response to the detected entanglement using the processor.

An oral care appliance having a housing, the housing including a tip and a body. The body is pivotably, rotationally, or translationally secured to the tip and further includes a sensor. The body also includes a control unit arranged to receive at least one input signal from the sensor and switch the oral care appliance from a first mode to a second mode in response to the at least one input signal from the sensor. The at least one input signal corresponding the tip being pivoted, rotated, or translated from a first position to a second position.

An object of the present invention is to provide a toothbrush that enables an appropriate brushing pressure to be more reliably recognized. A head portion (10) provided on a tip end side in a long axis direction and having a bristle tufting surface (11), a grip portion (30) disposed on a rear end side from the head portion, and a neck portion (20) disposed between the bristle tufting surface and the grip portion are provided. A sound generation portion (70) that generates a click sound due to deformation when an external force in a first direction orthogonal to the bristle tufting surface exceeds a threshold value is provided on a rear end side from the bristle tufting surface.

Systems and methods are generally described for an oral hygiene device. The oral hygiene device may include a handle portion and a head portion coupled to the handle portion and including a pick head interface. A pick head may be removably coupled to the pick head interface. The pick head may include a pointed pick member. An image capture device may be disposed in the head portion. The image capture device may be effective to capture image data representing images of an area proximal to a tip of the pointed pick member. A vibration element may be coupled to the pick head interface. The vibration element may be effective to vibrate the pick head.
