A cleaning brush is attached to an oral irrigator that includes a supply pipe stored in a body unit, which has a control unit on the lower side of a cleaning tank in which a cleaning solution is stored, such that cleaning is carried out by supplying the cleaning solution at a predetermined water pressure. The cleaning brush includes a supply hole to which the supply pipe is connected and which is provided on the upper side of a finger cover having an insertion space into which a finger is inserted. Nozzles are formed at predetermined intervals on the upper side of a nozzle unit to which the supply hole is connected. A brush protrudes from the peripheral upper side at which the nozzles are formed. The supply hole has a connection member protruding outward and has a connector having connector-connecting pipes formed on both sides thereof.

A toothbrush (100) including a head portion (120) formed from bamboo. A plurality of tuft holes (130) are formed into the head portion (120) and a bristle tuft (151) is positioned within each of the tuft holes (130) and secured by an anchor wire (200). The anchor wire (200) may be formed from a metal alloy that includes nickel. The anchor wire (200) includes a plurality of first grooves (210) in its first surface (203) and a plurality of second grooves (220) in its second surface (204). The grooves (210, 220) may have sidewalls (212, 213, 222, 223) that are perpendicular to its floor (211, 221). A width (WG1, WG2) of the grooves (210, 220) may be equal to a spacing (D2, D5) between the grooves (210, 220) and greater than a thickness (Ti) of the anchor wire (200).

The present invention relates to an electric toothbrush that includes a head part and a handle part having a shape connectable to the head part and supplying a driving voltage to the head part according to a user's control. The head part may include a toothbrush head formed with a plurality of bristle holes where toothbrush bristles are disposed and a first through hole and a second through hole spaced apart from each other, a head body extending from the toothbrush head and having an inner passage connected to the first through hole and the second through hole, a head cover which closes the inner passage of the head body, and a first electrode rod and a second electrode rod inserted through the inner passage of the head body, whose one ends being positioned in the first through hole and the second through hole, respectively, and the other ends being exposed to the outside through the head cover, respectively.

Described herein is an oral care implement comprising: a handle; and a head coupled to the handle, the head comprising a main body and a release component coupled to the main body, the release component comprising: a water-dissolvable matrix comprising a first polymer having a processing temperature greater than or equal to 130° C.; and a release agent comprising at least one of zinc oxide, potassium nitrate, and tetrapotassium pyrophosphate; wherein the release agent is dispersed throughout the water-dissolvable matrix.

A dental cleaning device, including a main body to facilitate gripping thereof, a plurality of bristles disposed on at least a portion of a first end of the main body to facilitate brushing of at least one tooth, and a floss compartment disposed within at least a portion of a second end of the main body, the floss compartment including a floss roll to coil a line of floss, a floss dispensing aperture connected to the floss roll to receive the line of floss therethrough from the floss roll, and a blade disposed around the floss dispensing aperture to cut the line of floss.

A brush head (100) and a method of making a tuft spike (20) and a brush head with a plurality of tuft spikes. The brush head includes a matrix (30) having a plurality of receptacles (32) formed therein. A plurality of tuft spikes are each formed of a plurality of bristle strands (22) arranged in a tuft (21) having a free end (25) and a proximal end (23) inserted in a spike body (24). Each tuft spike is disposed in one of the receptacles of the matrix. A brush head neck (40) has a distal platen (42) that is connected to and at least partially encompassed in the matrix.

An oral hygiene device, in particular a toothbrush, includes at least one application unit having a base body, further includes at least one handle unit, in particular a manual handle unit, having a base body, and including at least one coupling unit for releasably coupling the application unit to the handle unit, wherein the base body of the handle unit has a hardness and/or a density that is greater than a hardness and/or density of the base body of the application unit.

An oral care implement that includes a handle and a head. The head, which has an exposed front surface and an exposed rear surface, may include a support structure having a perimetric wall that defines a central opening and a monolithic cleaning unit including a pad located within the central opening and molded bristles extending from the pad. The support structure and the pad may collectively define the exposed front surface and the exposed rear surface of the head. Furthermore, the support structure may have a maximum thickness of 3 mm or less measured from a front surface of the perimetric wall to a rear surface of the perimetric wall.

A toothbrush includes a handle body made of a hard resin and a brush molded body (20) made of a soft resin and distal to the handle body. An insertion portion of the handle body protrudes toward the brush molded body, which has a head base portion (21), an insertion hole (22) into which the insertion portion is inserted and fitted, and a filament (23) that protrudes toward a front surface side of the head base portion. A maximum distance range between a base end of the filament and a back surface (21c) of the head base portion is 2.0 mm to 4.5 mm, and a ratio of the maximum length (L2) of the insertion hole to the maximum length (L1) of the head base portion is between 0.30 and 0.70.

The Ergonomic Handle Scraper includes an ergonomic handle device that may be adapted to perform a wide variety of tasks such as scrubbing, scraping, scooping, cutting, brushing, painting, sanding, grating, shaving, etc. The device may be produced in a wide variety of shapes and sizes and may be constructed from a wide variety of materials and manufacturing processes.
