The new paintbrush (19) includes a brush handle (1), a bristle carrier (11) and a ferrule (15). The brush handle (1) has a first end (3) including a brush handle snap element (4). The bristle carrier (11) has a first front side (36) including a bristle carrier snap element (12), the bristle carrier snap element (12) engaging the brush handle snap element (4) such that the bristle carrier (11) is fixedly connected to the brush handle (1). The bristle carrier (11) includes a plurality of recesses (23) and a plurality of bristles (20), the bristles (20) being arranged to form a plurality of bristle bundles (24), the bristle bundles (24) each being arranged to be gluelessly fixed in one of the recesses (23). The ferrule (15) is designed as one piece with the bristle carrier (11).

A toilet brush comprises a handle and a brush head. A backbone core is coupled to the handle. An inner support piece is further coupled to the backbone core and to the brush head. The handle further comprises an attachment area and the brush head further includes a scraping feature.

A mold insert and an injection-molding machine including the mold insert. The mold insert has at least one filament cavity and a stack of at least a first and second insert plates, wherein the first plate has a front face that closely abuts a front face of the second insert plate. A portion of the a filament cavity is provided in at least one of the front faces of the first and second insert plates such that the filament cavity is open at a top surface of the mold insert but does not extend to a bottom surface of the mold insert. A venting cavity is provided in the same front face of the insert plate in which the portion of the at least one filament cavity is provided.

In the related art, bristles that allow a current to flow to skin are exposed on a surface. Thus, there is a problem in that the bristles may swell and degrade due to a drug such as a hairdressing product or sweat and thus electroconductivity is lowered with use. Each of skin stimulation brush pins (10) of a skin stimulation brush (1) according to the present invention includes: a base bottom member (20) made of a metal, which is able to be connected to the electric circuit (6) so as to allow conduction of electricity from the electric circuit (6); a body member (30) being an elongated tubular body, which has a proximal end portion at which the base bottom member is disposed; an electrode member (50), which is connected to an opening of the body member on a distal end side, and has a distal end being exposed; and a metal shaft (40) inserted into a tubular inner portion of the body member, which is configured to couple the base bottom member and the electrode member.

Provided is a light irradiated toothbrush, in which light sources, irradiating light having mutually different wavelengths, are arranged in alternation at the bottom of waveguide bristles so that light of different wavelengths give rise to constructive interference which strengthens the intensity of the irradiated light, and the height of the light sources are varied on the basis of the wavelength of the light irradiated therefrom so as to effectively transmit light of short wavelengths to the waveguide bristles, and light having mutually different wavelengths are transmitted by means of the waveguide bristles, thereby effectively transmitting the light to the mouth of a user.

Some embodiments of the present invention provide a novel, twisted-in-wire type interproximal brush equipped with yarn strands. According to some embodiments, the yarn strands may be formed of nylon filament having compression memory characteristics.

This invention relates to an electric toothbrush including: a toothbrush head having a plurality of conductive bristles and at least one electrode supplied with a driving signal; a handle part connected to the toothbrush head and having a user-grippable shape; a battery disposed inside the handle part; and a signal supply located inside the handle part and configured to receive a voltage from the battery to generate an AC signal and a DC signal, and to generate the driving signal comprising a mixture of the AC signal and the DC signal to supply the electrode.

A brush includes a wire core, a round tip formed on a distal end of the wire core, the round tip being unitary with the wire core section and being formed by melting or welding a portion of the wire core at the distal end, and a molded tip attached to the wire core at the distal end via a ball-and-socket connection.

The present disclosure provides a method for preparing a porous antibacterial fiber brush. Fiber masterbatch made of ultra-fine reaming silica gel, silver-based antibacterial agent and other materials is melted, drawn, cut, polished and then dried to make the porous antibacterial fiber brush. A large number of micropores are distributed on the surface of the porous antibacterial fiber brush, which absorb cosmetic residues on the skin surface and tiny dirt in the pores, and realize efficient cleaning of the surface of human skin.

A gutter broom is provided. The gutter broom can include a mandrel, one or more carriers, each carrier removably coupled to the mandrel, and one or more bristle strips, each bristle strip removably coupled to one of the carriers. The gutter broom components can be recyclable and modular, requiring no tools for assembly or servicing.
