A toothbrush for promoting plaque removal, and a manufacturing method therefor are proposed. The toothbrush includes: a head part in which elements for cleaning teeth are arranged; a first electrode on the head part; a second electrode on the head part, the second electrode being spaced a predetermined distance from the first electrode and grounded; and a voltage supply part configured to superpose alternating current (AC) voltage and direct current (DC) voltage and apply the AC voltage and the DC voltage together to the first electrode.

A device for treating human keratinous material, in particular with the aid of an electric current. The device includes a reservoir containing a composition, in particular cosmetic or dermatological, to be applied to the keratinous material, and an end fitting for the application of the composition contained in the reservoir, the end fitting comprising a plurality of application members and a distributor. The distributor includes at least one storage cavity for the composition and supply orifices to conduct the composition from the storage cavity or cavities to the application members, and the distributor being configured so that the flow rate of the composition arriving at the application members is identical to within 20% for at least two application members, better for each application member.

A system and method for controlling sexual stimulation devices using motion-sensing controllers. The system comprises a male sexual stimulation device and a motion sensing controller configured to control the operation of the reciprocating linear motion driver. In operation, natural motions of a user with the motion sensing controller result in corresponding motions of the male sexual stimulation device such as reciprocal linear motions and rotational motions.

The present invention relates to an electrochemical device for releasing ions, comprising an electrical circuit comprising a first electrode and a second electrode adapted for providing a galvanic cell when the electrodes are exposed to a fluid constituting an electrolyte, and a boost converter adapted for amplifying a potential generated between the first and the second electrode. The electrical circuit further comprises a third electrode connected with an output side of the boost converter, wherein the second and the third electrode constitutes an electrolytic cell powered by the galvanic cell when the electrodes are exposed to a fluid. The present invention further relates to devices, such as a toothbrush or a shaver, adapted for being used in connection with a fluid, comprising such electrochemical device for releasing ions.

The present disclosure provides a novel massage gun, relates to the technical field of massage devices, and solves the technical problem that a wire between a handle and a massage head of the massage gun breaks easily when the massage gun moves at a high speed. The novel massage gun includes a gun body, a massage head arranged on the gun body, an auxiliary physiotherapy assembly arranged in the massage head, a main circuit board arranged in the gun body, and a connecting cable electrically connected to the auxiliary physiotherapy assembly and the main circuit board, where the connecting cable is made of a conductive wire resistant to high-speed bending. In the present disclosure, the connecting cable electrically connected to the auxiliary physiotherapy assembly in the massage head is made of the conductive wire resistant to high-speed bending, which solves the problem that the connecting cable breaks easily when the massage gun performs high-speed piston movement. Because the connecting cable does not break easily, electrical connection can be maintained, thereby prolonging the service life of the massage gun, and reducing use costs.

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.

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.
