Definitions

  • the present invention relates to a toothbrush head with a bristle carrier, on which a plurality of preferably tuft-shaped cleaning elements are fixed, wherein the bristle carrier has at least one movable rocker, which is articulated with a first end, which is remote from a handpiece Moen end of the toothbrush head, and with a free second end facing the handpiece-side end of the toothbrush head, wherein said rocker carries at least one row of cleaning elements.
  • the invention further relates to a preferably manual toothbrush with such a toothbrush head.
  • bristle carrier here does not necessarily mean that the carrier actually "real" bristles or bristle tufts, but also includes that instead of or in addition to bristle tufts other cleaning elements, for example in the form of elastomer strips or interdental tips, or other massage elements on the Borstenarme are attached.
  • the writings show US 6,178,582 . US 5,052,071 . US 6,073,299 . US 5,465,450 various embodiments of toothbrush heads whose bristle carrier regions are elastically formed so that different bristle carrier sections can twist each other.
  • a toothbrush head with a differently designed flexibility or mobility, in which at the brush head tip, ie from the toothbrush neck or handpiece furthest spaced portions of the bristle field are least yielding, while arranged closer to the handle neck bristle field sections give more or can bend away.
  • a rocker is provided on the toothbrush head, which protrudes backwards, so to speak, that is hinged at its end facing away from the toothbrush neck end on the toothbrush head and protrudes with its free end to the toothbrush neck.
  • Such a toothbrush head with backward projecting rockers shows, for example, the font US 2008/0184511 A1 , Specifically, two rockers are provided here, which form the legs of a U and are connected by a common central portion with which said rockers are attached to the body of the toothbrush head. The free ends of the rockers extend toward the toothbrush neck portion so that the bristle tufts mounted thereon can rock up and down.
  • the two rockers are in this case spaced apart and extend to the right and left of a central bristle carrier portion which is rigidly connected to the body of the toothbrush head so that the lateral bristle field sections formed by said rockers can rock up and down relative to the central bristle carrier portion.
  • the present invention has the object to provide an improved toothbrush head and an improved toothbrush of the type mentioned, avoid the disadvantages of the prior art and further develop the latter in an advantageous manner.
  • the cleaning elements furthest away from a longitudinal center plane of the toothbrush head are tilted at an acute angle with their free end inwards towards the longitudinal median plane.
  • the aforementioned longitudinal center plane means a plane containing the toothbrush longitudinal axis and parallel to the main direction of the bristle tufts or cleaning elements.
  • the inwardly inclined arrangement of the outer wing tufts when the bristle carrier has a movable pair of wings, the right and left substantially symmetrical with respect to the longitudinal center plane of the toothbrush are arranged and / or form outer edge portions of the bristle carrier.
  • the cleaning elements or bristle tufts are tilted with their free ends inwards to the longitudinal center plane, so that the width of the defined by the free ends of working surface is reduced.
  • the cleaning elements of the left and right rocker are thus inclined in opposite directions to each other.
  • the tendency of the cleaning elements on the rockers can take place at different angles.
  • the inclined arranged cleaning elements at an angle of inclination of 1 ° to 30 °, preferably about 5 ° to 20 ° relative to the longitudinal center plane inclined.
  • a central bristle carrier portion may be provided between the two wings, which is advantageously rigidly connected to a body of the toothbrush head so that the wings are moved relative to the central bristle carrier portion during up and down rocking.
  • On said central bristle carrier section can also Cleaning elements, in particular bristle tufts and / or elastomer strips to be attached, said central cleaning elements advantageously can not be arranged, ie parallel to the longitudinal center plane.
  • the cleaning elements fastened on the central bristle carrier section can however be tilted forwards or backwards in the longitudinal center plane, ie in the toothbrush longitudinal direction, preferably at an acute angle to a normal to the toothbrush longitudinal axis.
  • can also be dispensed with such a central bristle carrier portion ie between the right and left wings arranged no further bristle carrier portion is provided and / or said wings border directly to each other.
  • the arranged on the wings cleaning elements have respect to the articulation point or pivot point of the rocker depending on the distance from the free end of the rocker a different lever arm, ie depending on where on the rocker a cleaning element is arranged, it sets Putzantik more or less easy a deflection movement of the swingarm.
  • a further aspect of the present invention to the free end of the rocker towards a more massive and in particular kink-resistant cleaning element is provided.
  • the last cleaning element at the free end of a rocker is solid and in particular kink-resistant than the arranged in a central portion of the rocker and / or further to the first end of the rocker cleaning elements, said solid bristle tufts or cleaning element is advantageously at least as high as the further to the first end arranged cleaning elements.
  • the action of force, which moves the flexible wings during cleaning is initiated in a more targeted manner by the last or larger cleaning elements, as a result of which the deflection movement of the rocker is controlled more precisely. Small, thin bristle tufts would tend to break away unchecked.
  • depending on the brush holding angle of the user considerable pressure on the last, arranged at the free ends of the rocker cleaning elements can be exercised.
  • the more massive and / or kink-stiffer and / or cross-sectional surface larger design of the last or cleaning elements prevents twisting or dodging of the cleaning element and distributes the force acting on a larger area. This results in a more comfortable feel and reduces pricks on the gums.
  • said cleaning elements at the free end of the rockers are higher than the adjacent cleaning elements and / or the angeordeten in a central portion of the wings cleaning elements, so that the first bending of the rockers and the force is applied controlled at the beginning of the bend. Only from a certain evasive movement of the rocker engage the adjacent cleaning elements and / or arranged in a central portion of the rocker bristle tufts and distribute the load evenly for optimum feel, so that no local overload occurs.
  • the desired flexibility of the rockers can basically be achieved in various ways.
  • a movable mounting of the rockers can be provided with simultaneous support, for example by an elastic spring element.
  • the wings are rotatably articulated with their first ends to a body part of the toothbrush head and are themselves formed elastically deformable such that the aforementioned setting or evasive movement of the wings is achieved in the usual Putzandruck proceduren.
  • the wings are thus designed so elastic that sets under normal Putzanrise the desired deformation of the wings.
  • the rockers In order to achieve the desired flexibility with easy-to-produce, but on the other hand compact dimensions of the rocker, the rockers have in development of the invention at a free length in the range of about 20 mm to 70 mm, preferably about 30 to 50 mm, a modulus of elasticity in the range of 300 to 700 MPa, with a particularly favorable compromise between contour adjustment on the one hand and controllability of the cleaning movement on the other hand by a modulus of elasticity in the range of 350 to 500 MPa is achieved.
