Mascara according to the present invention includes: a handle; a brush rod extended from one side of the handle; and a tip member provided at one end of the brush rod, in which the tip member includes a base part shaped like a pillar, and a plurality of protruding parts protruding from an outer circumferential surface of the base part, and the base part and the protruding part are made of a metal material.

A cleaning wheel structure, which mainly comprises a cleaning unit, a universal joint and an elastic element, wherein the cleaning unit comprises a plurality of clamping jaws disposed around the circumference of the shaft thereof, and each of the clamping jaws has a positioning groove, the universal joint is disposed between the plurality of clamping jaws, the elastic element is disposed between the universal joint and the cleaning unit, wherein the outer surface of the universal joint is convexly provided with a positioning portion for embedding with the positioning grooves, with the above structure, when the cleaning unit is stuck and cannot be driven to rotate by the universal joint, the positioning portion repeatedly pushes each of clamping jaws outwardly to rotate and to be embedded in the next positioning groove, so that the universal joint no longer drives the cleaning unit.

A toothbrush includes a head with a new design and a handle that operates to move the head. The toothbrush head has multiple types of purpose-designed bristle-bundles precisely mapped to target specifically all dental-gingival surfaces and anatomically niches, including various dead-corner niches/surfaces that are usually not accessible by currently existing toothbrushes. Each cluster of bristle-bundles contains bristles of different sizes, diameters, hardness, lengths, angulations and colors. The head is designed to be inclined to accommodate both lingual and palatal surfaces. This toothbrush head also functions uniquely by coupling over dental arches and rotating so that the brush does not need to be lifted during movement from one end to the other. Further, moving the handle with respect to the brush head causes the width of the brush head to change to accommodate the different widths of the teeth along the dental arch.

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.

A computer-implemented method of training a user to effectively apply makeup using a computerized makeup brush, the method comprising the steps of receiving, from a makeup brush movement tracking system that comprises one or more sensors for sensing the movement of the makeup brush relative to a particular portion of a user's body, data representing a movement of the makeup brush relative to the particular portion of the user's body over a particular period of time as the makeup brush is used to apply makeup to the particular portion of the user's body, and using the data to generate and communicate, to a user, information regarding the movement of the makeup brush over the particular period of time.

A multi-purpose cleaning device is provided that can be used with multiple different types of cleaning attachments. The cleaning device includes a handle that is attachable to a socket device that includes several claw members. The claw members have interior portions that are contoured so that the space between the claw members forms a sphere-shaped socket. The cleaning attachments preferably include a ball portion that can be securely mated within the sphere-shaped socket. When the user prefers three degrees of freedom for the attachment, the ball has impeded rotation within the socket. When the user prefers one degree of freedom for the attachment, the ball also includes a rod or post that can releasably lock the ball to the socket.
