A personal hygiene implement comprises an axle that extends along a first longitudinal axis; a movable functional element comprising a base comprising a first side and an opposing second side, a first pillar extending from the first side of the base, wherein the first pillar comprises a piston chamber that is fluidly connected to a discharging through-hole, and at least one cleaning element extending from the second side of the base; and a fixation element comprising a piston which extends orthogonally to the first longitudinal axis; wherein the movable functional element is capable of rotatably oscillating around the axle, and the piston chamber engages with the piston to form a pump.

A dental cleaning appliance includes a fluid delivery system for delivering a burst of working fluid to the teeth of a user; and a control circuit for controlling the delivery of the burst of working fluid to the teeth of a user. The appliance has a first operational mode in which the delivery of the burst of working fluid to the teeth of a user is inhibited and a second operational mode in which the burst of working fluid to the teeth of a user is permitted. During use of the appliance, the control circuit is arranged to effect a transition between the first operational mode and the second operational mode automatically depending on a detected operational parameter of the appliance.

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.

A toothpaste dispensing toothbrush assembly for brushing teeth includes a handle that has an open end for accessing an interior of the handle. A cylinder is filled with a toothpaste and the cylinder is insertable into the open end of the handle. A pump is positioned within the handle to pump the toothpaste outwardly from the cylinder when the pump is turned on. A toothbrush head is removably attachable to the handle to brush the user's teeth. The toothbrush head receives the toothpaste from the pump to deposit the toothpaste on the user's teeth. A vibration unit is integrated into the handle and the vibration unit vibrates the toothbrush head when the vibration unit is turned on.

A pump toothbrush having a toothpaste tube to dispense dentifrice material to top of bristle head is disclosed. The pump toothbrush has a pump head with a resilient button to create an internal vacuum force to draw the dentifrice material from the toothpaste tube. The toothpaste tube is supported by width-limiting fingers to prevent total collapsing of sidewalls resulting in blocking of its flow channel. A self-closing spout is used for preventing backflow. For a manual pump toothbrush the toothpaste tube has an oval-shaped shoulder for mating with the oval-shaped shoulder of a detachable handle for fastening the toothpaste tube by threads. For an electrical pump toothbrush, a detachable endcap connector is used for swinging out the toothpaste tube from its handle for replacement. A sonic vibration model uses rubber molding to minimize vibration on the handle. A dual-rotary model has two rotary bristle elements engaged by gear teeth.

A mouthpiece for a dental cleaning device comprises a supporting structure configured to encompass a plurality of teeth of a dental arch. The supporting structure has an inner surface facing a tooth surface. At least one brushing chamber is provided at the inner surface side. The brushing chamber comprises a flexible wall part being deformable by pressurizing or depressurizing the brushing chamber. Bristles extend externally from the flexible wall part. In a method of brushing teeth, a plurality of teeth is encompassed by the mouthpiece, and the at least one brushing chamber is alternatingly pressurized and depressurized.

A dental cleaning appliance includes a handle, a fluid reservoir for storing a working fluid, and a fluid delivery system for receiving working fluid from the fluid reservoir, and for delivering the working fluid to the teeth of a user. The fluid reservoir is delimited by a wall and a movable member which is moveable relative to the wall to vary the volume of the fluid reservoir. An expansion chamber is located adjacent to the moveable member. The volume of the fluid reservoir decreases, and the volume of the expansion chamber increases, as fluid is supplied to the fluid delivery system during use of the appliance.

An oral care implement having an applicator and a cover member. In one aspect, the invention is an oral care implement comprising: a handle body extending along a longitudinal axis from a distal end to a proximal end; an applicator at the proximal end of the handle body, the applicator fluidly coupled to a reservoir containing an oral care material; a cover member having a cap portion, the cap portion comprising a resilient valve that is self-biased into a closed state so as to enclose the applicator; and wherein relative positioning between the applicator and the cover member can be altered between: (1) a storage state in which the cap portion of the cover member encloses the applicator and the resilient valve is in the closed state; and (2) an application state in which the applicator extends through the resilient valve and the resilient valve is in an open state.

Embodiments of the present disclosure provides oral applicators and methods for applying a substance to a site inside a mouth cavity of a human or an animal. An oral applicator includes a body adapted for being held by a human hand. The oral applicator further includes an applicator head extending from the body. The applicator head also includes an applicator surface distally located in relation to the body and adapted for use in applying the substance to the site. Further, the oral applicator includes a gas stream generator present near the applicator head for directing a stream of gas from the applicator head. The site may be dried during at least one of prior to, during and after an application of the substance. The stream of gas may be directed via an outlet proximate to the applicator surface.
