Definitions

  • the invention is based on a brush for personal care according to the preamble of claim 1.
  • Such a brush which is preferably provided for cleaning hand and toenails in the area of the nail bed, is known from DE 37 27 649 C1.
  • This version is unsuitable as a hand washing brush, since it only provides a plate-shaped brush, with which cleaning the whole hand is very tedious and time-consuming.
  • the object of the invention is therefore to provide a hand wash brush with a mains-independent motor drive, which enables cleaning of the entire palm including the fingernails.
  • the brush is of course also suitable for cleaning dirty feet and toenails.
  • a plurality of preferably cylindrical brushes are provided, which are arranged parallel to one another on a circular arc in the bearing plate of a kidney-shaped housing and can be exchanged.
  • the shape of the case is adapted to the natural curvature of the palm of the hand.
  • a gear is arranged, which is designed so that the brushes all have the same direction of rotation.
  • the brush rollers can be exchanged for tooth rollers, by means of which an endless toothed belt provided with bristles on the outside is circulated.
  • the device essentially consists of a housing 1 which, as will be explained in more detail later in connection with FIG. 2, encloses a direct current motor 9 with a reduction gear 10, a toothed belt transmission 4 and a set of rechargeable batteries 11.
  • the housing 1 has a kidney-shaped profile.
  • One narrow side is designed as a bearing plate 2, in which a plurality of shafts 8 are rotatably mounted in bushings with a shaft seal.
  • the bearings 7 are arranged on one of two circular arcs K1 and K2.
  • the profile of the rear grip 20 with which it forms the housing 1 is adapted to the shape of the circuit board 2. Otherwise, the shape of the housing 1 is adapted to the natural curvature of the palm of the hand.
  • a slide 22 is integrated in the handle shell 20 in a watertight manner.
  • a switching magnet is attached to its underside, which is part of a magnetic switch.
  • the handle shell has two guide grooves 25 on the right and left (only one each is visible in the illustration), which are provided for receiving a splash guard 40 (FIG. 2).
  • the shafts 8 have an axial blind hole for releasably receiving brush rollers 30.
  • the stub shafts protruding from the board 2 are cross-slotted.
  • the brush rollers 30 have a pin 32 which is embedded in the shaft body and which has diametrically arranged detents 33. In the plugged-on state, the brush rollers 30 are guided axially via their pins 32 in the shaft hole of the respective shaft 8, while the side lugs 33 engage in the transverse slots of the shafts 8 and cause a positive connection.
  • the brush rollers 30 are provided with a plurality of bristle tufts 31 on the circumference and on the face side according to FIG.
  • the pitch of the shafts 8 is only slightly larger than the diameter of the roller body 34.
  • the bristle tufts 31 of adjacent brush rollers 30 are therefore arranged in a gap.
  • FIG. 2 shows the hand washing brush according to FIG. 1 in a different perspective view with the handle shell 20 removed, so that the part of the device protected by the handle shell is visible.
  • a transmission board 3 is arranged on the inside.
  • the shafts 8 are rotatably supported with their rear end.
  • a toothed belt wheel 5 is fixedly arranged on each of the shafts 8.
  • the DC motor 9, which forms a unit with a reduction gear 10, is flanged to the transmission board 3.
  • the drive shaft (not visible in the illustration) protrudes into the space between the two boards 2 and 3 and carries a toothed belt wheel 5 at the end the motor 9 driven in the same direction of rotation.
  • the motor 9 is supplied with power by a set of rechargeable batteries 11, which are connected in series in a manner not shown to provide the necessary voltage.
  • a magnetic contact 13 which can be actuated in a contactless manner when the handle shell 20 is attached via the switching magnet attached to the slide 22.
  • the grip shell 20 has a charging socket 23 which is connected to the batteries 11 via electrical lines 12 and allows connection to an external charging source.
  • the charging socket 23 can be protected against splash water by a protective cap 24.
  • the attached handle 20 is secured by screws 21.
  • a seal 14 embedded in an annular groove in the bearing plate 2 ensures that the grip shell 20 is sealed off from the plate 2.
  • a splash guard 40 which covers the side of the hand washing brush that is not currently being used.
  • the splash guard 40 can be changed over.
  • the splash guard 40 has two guide jaws 41 which are arranged at a distance from the clear width of the grip shell 20 and corresponding to the Outer contour of the grip shell 20 are formed in the area between the paired guide grooves 25.
  • the longitudinal edges of the guide jaws 41 are designed as strip-shaped locking elements 42. When plugged in, the latching elements 42 engage in a form-fitting manner in the guide grooves 25 in the grip shell 20 and ensure a stable hold of the splash guard.
  • toothed rollers can be used which are spanned by a toothed belt provided with bristles on the outside.
  • the toothed belt is freely tensioned in the area of the concave curvature of the toothed rollers. This enables him to adapt to the unevenness of the hand to be cleaned.
