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.

The subject of the present disclosure is an electric toothbrush having a head part with a rotating working element and equipped with technical means to drive the working element and to change the direction of its rotating movement.

A method and device for cleaning drinkware without using electricity are disclosed including a handle, a shaft connected to the handle, a cleaning brush connected to the shaft, and a top section connected to the cleaning brush; when the interior bottom of a drinkware is pressed down, creating a pressure upon the top section, the cleaning brush is rotated in a first direction, and when the pressure decreases, the cleaning brush rotates in a second direction opposite to the first direction.

Oscillating mechanisms with side brushes are presented including: a base assembly, the base assembly including, a base plate, a rotating axle extending perpendicularly from the base plate, at least one arm coupled with the rotating axle, a slot along a path of the at least one arm, and a first anchor positioned along a proximal end of the slot; and a brush assembly slidingly coupled with the base assembly, the brush assembly including, a hub slidingly coupled with the base plate along the slot, a side brush coupled with the hub, the side brush extending outwardly from the base assembly, a second anchor positioned along the hub, and a return spring coupled with the first anchor and the second anchor. In some embodiments, mechanisms further include: at least two arms coupled with the rotating axle, the at least two arms positioned at least 90 degrees apart from each other.

An electric toothbrush includes a main body, a head connected to the main body, having a stem and a rotating element rotating in first and second rotation directions, a transmission shaft rotating the rotating element, a motor generating rotary motion transmitted via transmission shaft to the rotating element, and first, second and third push switches. Pressing the first switch, which is pressed when the transmission shaft is inclined in a first flexion direction, causes rotation of the rotating element in the first rotation direction. Pressing the second switch, which is pressed when the transmission shaft is inclined in a second flexion direction, causes rotation of the rotating element in the second rotation direction. Pressing the third switch, which is pressed by the transmission shaft when inclined with respect to the main body in a third flexion direction, causes rotation of the rotating element in the first or second rotation direction.

An electric toothbrush having bristle driven pulsation includes a brush head having a bristle holder and bristle tufts attached to the bristle holder. The bristle tufts and corresponding bristles are disposed at a perpendicular and/or a non-perpendicular angle with respect to a mounting surface of the brush head. The electric toothbrush also includes an electric toothbrush handle removably attached to the brush head. The electric toothbrush handle includes a linear motor configured to drive the bristle holder via a gearing structure coupled to the linear motor and the bristle holder. The linear motor causes the bristle holder to rotate clockwise and counterclockwise at a rotation frequency which exceeds a rotation frequency threshold (e.g., 100 Hz, 120 Hz, etc.). The linear motor also causes the brush head to vibrate in a direction toward and away from a contact surface in synchronization with the rotation of the bristles.

A personal hygiene device has a drive unit having a support, a stator fixedly mounted at the support, and an armature spring-mounted at the support for driven linear oscillating motion along a first longitudinal direction parallel to or coinciding with an x-axis of an x-y-z coordinate system. The armature has a center of gravity located in rest at a coordinate [x.sub.a, y.sub.a, z.sub.a], and a drive shaft fixedly coupled with the armature and having a center of gravity located in rest at a coordinate [x.sub.d, y.sub.d, z.sub.d]. A first treatment head assembly, detachably connected to the drive shaft, has a center of gravity located in rest at a coordinate [x.sub.t1, y.sub.t1, z.sub.t1]. A secondary mass element, spring-mounted at the support for essentially linear oscillating motion along the first longitudinal direction, has a center of gravity located in rest at a coordinate [x.sub.m, y.sub.m, z.sub.m]. At least the coordinate [x.sub.a, y.sub.a, z.sub.a] of the center of gravity of the armature has an offset in at least one of the y-direction and z-direction with respect to the coordinate [x.sub.d, y.sub.d, z.sub.d] of the center of gravity of the drive-shaft or with respect to the coordinate [x.sub.t1, y.sub.t1, z.sub.t1] of the center of gravity of the first treatment head assembly, i.e., y.sub.ay.sub.d and/or y.sub.ay.sub.t1 and/or z.sub.az.sub.d and/or z.sub.az.sub.t1; and the secondary mass element is configured such that the coordinate [x.sub.m, y.sub.m, z.sub.m] of the center of gravity of the secondary mass element is aligned with the coordinate [x.sub.j, y.sub.j, z.sub.j] of the joint center of gravity of the drive shaft, the first treatment head assembly and the armature in the at least one offset direction, i.e., y.sub.m=y.sub.j and z.sub.m=z.sub.j, so that a line connecting the coordinate [x.sub.m, y.sub.m, z.sub.m] of the center of gravity of the secondary mass element and the coordinate [x.sub.j, y.sub.jz.sub.j] of the joint center of gravity is parallel to or coincides with the x-axis.

The invention relates generally to the field of medical devices and, more specifically, to a handheld device that stimulates the meibomian gland of the eyelid mechanically, and specifically stimulates the meibomian glands of the eyelid to treat Meibomian gland dysfunction, also known as Dry eye and chronic marginal eyelid inflammation.

A tool for attaching a treatment head to a wash media element of a vehicle wash component includes a nose portion and a handle portion. The nose portion is sized to pass through an opening in the wash media element. The nose portion includes a slot for receiving and retaining a base portion of the treatment head to secure it to the wash media element such that the nose portion and treatment portion are disposed on opposite sides of the wash media element.
