Elektrische Zahnbürste mit einem rotierenden Borstenkopf Die Erfindung betrifft eine elektrische Zannbürste (10) mit einem rotierenden Borstenkopf (11) nach dem Oberbegriff des Anspruchs 1 Die vorgegebene Zahnbürste ist mit einem rotierenden zylindrischen Borstenkopf ausgestattet, der automatisch die Rotationsrichtung wechselt, sodaß das Gebiß stets vom Zahnfleich weg, hin zur Zahnkrone gebürstet wird. Electric toothbrush with a rotating bristle head The invention relates to an electric Zannbrush (10) with a rotating bristle head (11) according to the preamble of claim 1 The given toothbrush is with a rotating equipped with a cylindrical bristle head that automatically changes the direction of rotation, so that the dentition is always brushed away from the gums towards the crown of the teeth.
Es ist bekannt, daß bei der Reinigung des Gebißes es von gesundheitlichem Vorteil ist, die Zähne stets in einer Richtung und zwar vom Zahnfleich weg zur Zahnkrone hin zu bürsten.It is known that when cleaning the dentition it is of health The advantage is that the teeth are always in one direction, away from the gums to the crown of the teeth to brush.
Die im Handel vorhandenen Zahnbürsten erfüllen jedoch diese Anforderung nicht. Sie sind mit einem vibrierenden Borstenkopf ausgestattet; durch das Vibrieren des Borstenkopfes wird das Zahnfleich hin und her geschoben, womit eine Zerstörung des Gewebes und später Zahnfleichblutungen häufig eintretten.However, the toothbrushes available on the market meet this requirement not. They are equipped with a vibrating bristle head; by vibrating of the bristle head, the gums are pushed back and forth, causing destruction of the tissue and later gum bleeding often occur.
Der Erfindung liegt deshalb die Aufgabe zugrunde, die oben erwähnten negativen Nebenwirkumgen der gebräuchlichen elektrischen Zahnbürsten zu beseitigen und die vielfältigen Drehrichtungen des Bürstenkopfes des neuen Geräts automatisch zu steuern.The invention is therefore based on the object mentioned above Eliminate negative side effects of conventional electric toothbrushes and the various directions of rotation of the brush head of the new device automatically to control.
Diese Aufgabe wird bei einer gattungsgemäßen Einrichtung durch die kennzeichenden Merkmale des Anspruchs 1 gelöst.This task is achieved in a generic device by the characterizing features of claim 1 solved.
Bei dem Gebrauch eines rotierenden Borstenkopfes müssen - in Abhängigkeit mit der Drehrichtung der Borsten - acht Gebißzonen unterschieden erden. Sie sind: - 1. vier Zonen für die obere Gebißhälfte: die links-außen und die rechts-innen Zonen entsprechen der Drehung der Borsten in Uhrzeigersinn, während die rechts-außen und die links--innen Zonen der Drehung gegen dem Uhrzeigersinn entsprechen; - 2. vier Zonen für die untere Gebißhälfte mit den zu 1. entgegengesetzen Drehrichtungen für den Borstenkopf.When using a rotating bristle head - depending on earth with the direction of rotation of the bristles - eight dentition zones. They are: - 1. four zones for the upper half of the dentition: the left-outside and the right-inside Zones correspond to the rotation of the bristles clockwise while the right-outside and left-inside zones of counterclockwise rotation correspond; - 2. four zones for the lower half of the dentition with those opposite to 1. Direction of rotation for the bristle head.
Nit der Umschalttaste (14) wird lediglich die Information "oben" oder "unten" für die betreffende Gebißhälfte angegeben.With the shift key (14) only the information "above" or "below" indicated for the relevant half of the dentition.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß statt einer Auf-und-ab-Bewegung der Borsten, wie üblich, jetzt in einer gleichmäßigen und stets vom Zahnfleich zur Zahnkrone hin gerichteten Bewegung die Borsten rotieren, womit Verletzungen am Zahnfleich vermieden werden und außerden können so-kleine Speisepartikeln nicht mehr unter das Zahnfleich geschoben werden.The advantages achieved with the invention are in particular: that instead of an up and down movement of the bristles, as usual, now in a steady one and the bristles always rotate from the gum to the crown of the tooth, with which injuries to the gums can be avoided and also small ones Food particles are no longer pushed under the gums.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing and is described in more detail below.
Es zeigen: Fig. 1 eine schematische Skizze einer erfindungsOremaßen Zahnbürste, Fig. 2 eine schematische Skizze der Zahnbürste'mit dem eingebauten Schwerkraft schalter und eie Querschnitt des BorsteMopfes, Fig. 3 eine Darstellung der elektrischen ontaktzonen für den Schwerkraftschalter, und Fig. 4 eine schematische Skizze des elektrischen Schaltplans.They show: FIG. 1 a schematic sketch of an inventive dimension Toothbrush, Fig. 2 is a schematic sketch of the toothbrush with built-in gravity switch and a cross section of the bristle head, Fig. 3 shows a representation of the electrical contact zones for the gravity switch, and FIG. 4 is a schematic sketch of the electrical wiring diagram.
Das Ausführungsbeispiel der Erfindung zeigt eine erfindungsgemäße Zahnbürste mit einem rotierenden Borstenlropf. The embodiment of the invention shows one according to the invention Toothbrush with a rotating drop of bristles.
Der zylindrische Borstenkopf (11) der Zahnbürste hat einen Durch messer von 12 mm und einer Drehachse von 4 mm Durchmesser.The cylindrical bristle head (11) of the toothbrush has a diameter of 12 mm and a rotation axis of 4 mm diameter.
Die Drehachse (12) verläuft innerhalb des Bürstenstils(15) und ist a Ende mit dem Elektro-MOtor gekoppelt.The axis of rotation (12) runs within the brush style (15) and is a end coupled with the electric motor.
Die Torstenhappe (1)) verdelt eine Iälfte des borstenl;opfcs und dient dem Schutz der Mundschleimhäute.The Torstenhappe (1)) throws one half of the bristle head and serves the protection of the oral mucous membranes.
Mit der Taste (14) wird das Gerät vom Benutzer eingeschaltet.The device is switched on by the user with the button (14).
Er schaltet auf "oben", beziehungsweise auf "unten, wenn er die obere bzw. die untere Gebißhälfte zuerst bürsten möchte.It switches to "above", or to "below" if it is the upper one or want to brush the lower half of the teeth first.
Danach werden alle'nötigen Drehrichtungen der Borsten als Steuerungsbefehle an den Elektro-Motor automatisch bestimmt.Then all the necessary directions of rotation of the bristles are used as control commands automatically determined to the electric motor.
Die automatische Steuerung (Fig. 4) besteh-t aus einem Schwerkraftschalter (20) , aus einem Mikroprozessor (41) und vier Wiederstände (42) mit je ca. 10 mn.The automatic control (Fig. 4) consists of a gravity switch (20), from a microprocessor (41) and four resistors (42) with approx. 10 mn each.
Der Schwerkraftschalter (20) läßt sich aus einem Kunststoffrohr erstellen, das zunächst als Ring geformt wird (Fig. 3).The gravity switch (20) can be made from a plastic tube, which is initially shaped as a ring (Fig. 3).
Entlang der inneren Wand des Ringes verlaufen zwei elektrischen Kontakte wie vier paarweise parallele Fäden. Die Ausbreitung der Kontakten sind mit den Winkeln X = 1700 und @= 100° der Fig. 3 angegeben. Die neutralen Winkeln sind T = 200 und 6= 350 (2 x Eine mit der Schwerkraft bewegliche Metalkugel befindet sich in dem Innern des Ringes und stellt die elektrische Verbindung zwischen den Polen her.Two electrical contacts run along the inner wall of the ring like four pairs of parallel threads. The spread of the contacts are with the angles X = 1700 and @ = 100 ° given in FIG. 3. The neutral angles are T = 200 and 6 = 350 (2 x a metal ball that can be moved by gravity is located inside the ring and provides the electrical connection between the poles here.
Die endgültige Form des Schalters wird erreicht, indem der Ring um die Achse A-B (Fig. 3) um 90°geborgen wird ((20) Fig.2).The final shape of the switch is achieved by placing the ring around it the axis A-B (Fig. 3) is recovered by 90 ° ((20) Fig.2).
Der Schaltzustand (ltobentl od. "unten") des Schalters (14) und des Schwerkraftschalters (20) werden vom logischen Gattersystem (41) als Bürstenposition interpretiert, und anschließend von einem Relais oder äquivalenten Gatterzusammenschaltung die Drehrichtung des Motors (44) bestimmt.The switching state (ltobentl or "down") of the switch (14) and the Gravity switch (20) are used by the logic gate system (41) as a brush position interpreted, and then by a relay or equivalent gate interconnection determines the direction of rotation of the motor (44).
