Definitions

  • toothbrushes are manually operated, and effective cleaning of the teeth is reliant on the dexterity of the hands of the user.
  • manual cleaning of the teeth can be a difficult task that cannot be performed effectively.
  • manual cleaning of the teeth can be improved upon.
  • a variety of powered toothbrushes are available. Ordinarily it has been the case of applying an oscillatory movement to an arm carrying the bristle head from a small mains or battery operated electric motor located in the toothbrush handle or body from which the arm extends.
  • a toothbrush comprises a carrier, a support arm rotatively secured to the carrier, a cleaning head at the outer, free end of the support arm, and a drive means associated with the carrier to cause the rotation of the arm.
  • the support arm may be selectively rotatable in opposite directions for more effective cleaning of the fronts and backs of the upper and lower sets of teeth.
  • the selection of rotation is to cause a rotation of the cleaning head that is in the direction from the gum to the outer extremity of the teeth, to avoid the possibility of damage being caused to the gums.
  • the cleaning head may be caused to reciprocate in an axial direction, whereby to provide a compound movement of the cleaning head that adds significantly to the cleaning action on the teeth.
  • the carrier may be a housing to serve as the handle of the toothbrush, and a small mains or battery operated electric motor may be located in the housing to apply a rotary drive to the support arm.
  • the carrier may be attached such as by a flexible drive to a remote motor, with a connection through the carrier to the support arm.
  • the support arm may be detachably secured to the carrier, or the cleaning head may be detachably mounted on the end of the support arm.
  • one carrier unit can serve a number of users, each of whom would have their own support arm/brush head for attachment to the carrier as and when cleaning of their teeth is required.
  • the cleaning head may be of bristle construction and the bristles of the bristle head may be of uniform length to provide a bristle head of generally cylindrical character.
  • the bristle head is shaped to provide a tooth-like profile at the periphery of the bristle head, and further preferably, the crests of the tooth-like profile have a helical configuration along the length of the bristle head.
  • the cleaning head can be formed as a generally cylindrical member of a relatively soft or resilient material, such as for example foam rubber, to suit users with a medical condition making it essential that the gums are not damaged and caused to bleed, or those with gum disorders of a painful nature.
  • a relatively soft or resilient material such as for example foam rubber
  • a guard to overlie the rotary cleaning head to one side.
  • the toothbrush of the invention can be further enhanced by providing a fluid supply to the cleaning head such as down a bore formed in the support arms and associated o apertures through the wall of the support arm and communicating with the cleaning head.
  • the toothbrush of the invention can be still further enhanced by providing for the vacuum extraction of fluid from the mouth of the user, either through the bore previously used to supply fluid, or through 5 a separate channel formed in or associated with the support arm to allow the continuous supply and removal of fluid during use.
  • a bleed hole to atmosphere is associated with the vacuum extraction means and to avoid an excessive build-up of vacuum in the mouth of the user should the mouth inadvertently close on to the cleaning head.
  • the cleaning head can simply be placed by the user at the junction of the teeth and the gums and the drive activated, and with the cleaning head rotating, the toothbrush moved gently over the length of the teeth.
  • the rotation of the brush generates a vertical scrubbing action against the teeth, ideally suited to cleaning not only the face of the teeth but also the junction between adjacent teeth.
  • the direction of rotation can be selected such that when cleaning the front or the back of the upper or the lower set of teeth, the direction of rotation can be selected to drive debris towards and clear of the outer edge of the teeth.
  • the toothbrush of the invention enables both left hand and right hand usage.
  • the additional reciprocatory motion applied to the cleaning head adds noticeably to the cleaning action on the face of the teeth without affecting the ability of the toothbrush to avoid damage to the gums and lips of the user.
  • Figure 2 is an end view of the toothbrush of Figure 1;
  • Figure 3 is a schematic cross-sectional view of the toothbrush of Figure 1 ;
  • Figure 4 corresponds to Figure 3 but shows a second embodiment of toothbrush in accordance with the invention.
  • Figure 5 is a perspective view of a third embodiment of toothbrush in accordance with the invention.
  • a toothbrush 1 is formed by a carrier or handle portion 2, and a support arm 3 on which is positioned a cleaning head 4.
  • reduction gearing 5 is provided to connect the support arm 3 to a motor 6 located in the carrier, the motor 6 being driven by batteries 7 also located within the carrier.
  • On the carrier switch means 8 are provided whereby the direction of drive of the motor can be selectively reversed, and whereby to cause a rotation of the support arm and hence the cleaning head in a required direction.
  • the arrangement may be such that in addition to a battery drive, mains drive can be employed.
  • a connection 9 to mains may be provided, which connection to mains may also be employed to recharge the batteries 7, when rechargeable batteries are employed.
  • the carrier is so-formed as to provide a guard 10 to overlay a part of the cleaning head to protect the lips, cheeks, and tongue of the user.
  • the cleaning head 4 is preferably of bristle construction, the bristles 11 of which are of uniform length to form a generally cylindrical structure. Desirably, however, the bristles are shaped to provide a tooth-like profile at the periphery, and the crests of the tooth-like profile having a helical configuration along the length of the cleaning head.
  • the cleaning head 4 can simply be placed by the user at the junction of the teeth and gums, and the switch 8 activated to cause the cleaning head 4 to be rotated.
  • the direction of drive is selected to provide a downward motion of the bristles 11 from the gum to the edge of the teeth, and when it is the back of the teeth that are being cleaned, an opposite direction of drive is selected again to result in a bristle movement direction from the gum to the teeth edge.
  • the support arm 3 may be formed from a tough plastics material, and at a point along the length of the support arm, where it is positioned within the carrier 2, a sector or a sleeve 12 of ferro-magnetic material may be provided, surrounded by a small solenoid 13 connected to the batteries 7 via the switch 8, with an interposed make-and- break contact 14.
  • a return spring 15 is provided to the opposite side of the reduction gears to the support arm.
  • the reduction gearing 5 may have one of its gear wheels of an enlarged length to permit a sliding motion as between the two gears without the disconnection of the one from the other.
  • a water inlet 16 and a water outlet 17 may be provided on the carrier, for connection to a water feed tube 18, and a vacuum extraction tube 19 leading to transportable equipment 20 on which is provided vacuum pump means and water supply means.
  • inlet and outlet water passageways are provided from the inlet 16 and outlet 17 leading to the cleaning head 4.

Abstract

La présente invention concerne des brosses à dents et, plus particulièrement, des brosses à dents mécaniques. Une telle brosse à dents a pour objectif de réduire au minimum le mouvement de la brosse provoqué manuellement, cet objectif étant atteint grâce à une structure comprenant un support (2), un bras de support (3) monté rotatif sur celui-ci, une tête de brossage (4) située à l'extrémité extérieure, libre, du bras du support, et un dispositif de commande (6) relié au support, qui entraîne la rotation du bras. Plus avantageusement, le système permet d'effectuer sélectivement le mouvement de rotation du bras de support dans des directions opposées.
