Abstract: The present invention relates to a toothbrush attachment for an electric toothbrush, having a preferably tube-shaped body part on which an electronic module, such as a transponder, is mounted. The invention further relates to a method for producing such a toothbrush attachment and to a toothbrush having such a toothbrush attachment. According to the invention, the at least one electronic component is welded into the toothbrush attachment. According to the invention, the electronic component is encapsulated in an intermediate space between two body parts of the toothbrush attachment and is closed by at least one weld seam bonding the two body parts to each other. This ensures comprehensive protection of the electronic component by the body parts covering it.

Abstract: The invention pertains to a method for locally heating an object with electromagnetic radiation and substantially simultaneously cooling the immediate vicinity of the object region to be heated by a flowing fluid. The inventive method is characterized in that the flowing fluid and the electromagnetic radiation emitted in the toward the region to be heated are guided along paths that are spatially separated from one another.

Abstract: A toothbrush head has a tooth cleaning element extending from the head. The head is divided into at least two portions which can be moved independent of each other. The tooth cleaning element is rotatable relative to that portion of the head from which it extends.

Abstract: The invention is directed to a long-hair cutter unit (LHS) for a dry shaving apparatus (TR), with a dimensionally stable cutting comb (11) having one cutting teeth row (17) and at least one bearing surface (110) for at least one engagement surface (120) of an arcuately curved, hardened cutting blade (12) having one cutting teeth row (18) and held in engagement with the cutting comb (11) by a pressure of at least one spring element (19, wherein the curvature of the hardened cutting blade (12) is partially configured by means of a forming process such as to ensure conformance and slidable contact of the engagement surface (120) of the cutting blade (12) with the bearing surface (110) of the cutting comb (11) by means of the partial curvatures as well as their restoring forces under the action of the pressure of the spring element (19).

Abstract: The invention is directed to a method and a device for bending a component (71) made of a thermoplastic material, and to the component (71) itself, in particular a sleeve-shaped component having a straight shank (72), for use in a personal care appliance such as a dental care, a hair care, a kitchen apparatus or the like. A holding means (70) is provided for supporting the component (71) to be formed to shape, and the component (71) is formed by at least two tools (76, 84, 92) arranged for movement relative to each other, and a heating unit is provided for heating the component (71) in its condition as formed.

Abstract: A method for bending a component made of a thermoplastic material. The component involved is in particular a sleeve-shaped component for a personal care appliance such as a dental care apparatus or the like. For the component to be bent it is heated up to the plastic's softening point. The component is brought into engagement with a forming rail and, during a relative movement of the component and the forming rail, is bent against the forming rail by means of a bending tool. As this occurs, the engagement surface between the component and the forming rail varies continuously.

Abstract: A cutter which performs the function of either the outer or the inner cutter in a cutting device comprised of outer and inner cutters of an electric shaving apparatus or an electric beard trimmer. The cutter includes in its cutting area configured as a plane sliding surface a plurality of teeth extending from a comb strip with slots therebetween and with cutting edges formed on the tooth edges. Arranged on the cutter are one or several wall portions angled relative to the cutting area. The cutting area of the cutter includes a blade made of hardened sheet steel, with the teeth of the blade being produced by etching. The wall portions of the cutter are formed by welding one or several formed sheet metal sections to the blade. The weldment is effected such that the resulting rise in temperature of the blade is so low that the hardened sheet metal material is neither adversely affected by deformations nor exposed to significant losses in respect of hardness and wear resistance.

Abstract: Handle (1) attached to a domestic container (2) by means of an adhesive (3) comprises spacing strips or projections (1.2) on the edge of its contact area (1.1), said strips or projections exactly defining the layer thickness of adhesive (3) and ensuring access of ambient air to the adhesive layer through a circumferential laterally open air gap.

Abstract: An axially compact hairdryer includes a cylindrical housing having an air inlet and an air outlet at opposite ends thereof. An electric motor is centrally mounted within the housing by a pair of spaced apart support grates secured to the housing perpendicular to the air flow and a cylindrical heating element support body is carried by the support grates and located in concentric spaced relation between the housing and the motor. The heating element is wound about the support element. A fan is operatively connected to the motor for moving air from the inlet to the outlet over the heating element. Air directing vanes are attached to one of the support grates between the motor and the fan.

Abstract: An axially compact hair dryer includes a cylindrical outer housing 1, an air outlet 2 at one end of the housing, an air inlet grate 3 at the other end, an electric motor 4 centrally mounted within the housing and driving a blower fan 5, and a generally cylindrical electric heating element 7 disposed in the otherwise wasted annular space between the motor and the housing.
