Abstract

In order that the toothbrush can carry out movements back and forth through about 65 DEG , two damping elements (18) are connected to the rotor of the oscillating armature motor. The live parts, such as cable (20), contact carrier (23), coil (11) and magnetic switch (19), and the electric wires are provided with a sheathing. This compound can be made of thermoplastics or thermosetting plastics or of elastomer. The risk of accidents in the case of an insulation fault is thus avoided. <IMAGE>

Description

Elektrische Zahnbürste mit SchwingankermotorElectric toothbrush with oscillating armature motor

für Netzspannung Elektrische Zahnbürste mit Schwingankermotor für Netzspannung D'e vorliegende Erfindung betrifft eine elektrische Zahnbiirste mit Schwingankermotor für Netzspannung, die gegenüber den beknnten, bisher im Handel erhältlichen Zahnbürsten dieser Art betriebssichejer konstruiert ist Die spannungs führende Einheit der bisher bekannten elektrischen zahnbürsten ist nicht ummantelt, so dass eine gewisse Unfallgefahr besteht. In der Tat kann ein elektrischer Isolatiosfehler hei einer Spannung von 220 V in einer mit der mundpartie in Berührung stehenden Zahnbürste schwerwiegende Folgen haben.for mains voltage Electric toothbrush with oscillating armature motor for mains voltage The present invention relates to an electric toothbrush with oscillating armature motor for mains voltage, which compared to the known ones, so far in the trade Available toothbrushes of this type are designed to operate safely leading unit of the previously known electric toothbrushes is not coated, so that there is a certain risk of accidents. Indeed, an electrical isolation failure can occur at a voltage of 220 V in one that is in contact with the mouth Toothbrush can have serious consequences.

L-r Hauptzweck der vorliegenden Erfindung' besteht nun darin, ese mögliche Unfallgefahr auszuschliessen, indem die spdnnungsführenden Teile der elektrischen Zahnbürste mit einer isolierencen Ummantelung versehen sind.L-r main purpose of the present invention 'is now to ese Eliminate possible risk of accident by removing the voltage-carrying parts of the electrical Toothbrushes are provided with an isolating coating.

E n Ausführungsbeispiel des Erfindungsgegenstandes wird nachzeigend anhand der Zeichnung näher erläutert. Die Zeichnung zeigt einen Längsschnitt durch eine erfindungsgemässe Zahnbürste.An exemplary embodiment of the subject matter of the invention will be indicative explained in more detail with reference to the drawing. The drawing shows a longitudinal section through a toothbrush according to the invention.

Die in der Zeichnung veranschaulichte Zahnbürste weist einen nqlichen Gehäusekörper 10 auf, der als Handgriff dient und in Le:lchem die Spule 11 eines Schwingankermotors untergebracht ist.The toothbrush illustrated in the drawing has a similar one Housing body 10, which serves as a handle and in Le: lchem the coil 11 of a Oscillating armature motor is housed.

Der Schwingankermotor weist in an sich bekannter Weise einen Spulenkörper und einen Spulenkern auf. Ein auswechselbarer Bürtenkörper 12 wird von einem aus dem Gehäuse 10 ragenden Abschnitt 1 einer Welle 14 getragen. Diese Welle 14 wird von zwei sie umo benden Torsionsfedern 15 in ihren Schwingungen orientiert. Das freie Ende der Torsionsfeder 15 steht mit der Mitnehxerscheibe 16 des Schwingankermotors in Wirkungsverbindung. Der Anker des Motors mit der Mitnehmerscheibe 16 sind in Lagerzapfen 17 des Gehäuses gelagert. Die Torsionsfedern 15, welche die Welle immer wieder in ihre Ausgangslage bzw. in ihre 0-Stellung bringen sowie die übrigen genannten Bauteile sind an sich bekannter Bauart und sollen daher nicht eingehender umschrieben werden.The oscillating armature motor has a coil body in a manner known per se and a bobbin. A replaceable brush body 12 is made from one the housing 10 projecting portion 1 of a shaft 14 is carried. This wave 14 is by two they umo benden torsion springs 15 oriented in their vibrations. That free The end of the torsion spring 15 is connected to the driving disk 16 of the oscillating armature motor in effect connection. The armature of the motor with the drive plate 16 are in Bearings bearing pin 17 of the housing. The torsion springs 15, which the shaft always Bring them back to their starting position or their 0-position as well as the others mentioned Components are of a known type and should therefore not be described in more detail will.

Zwei zwischen der Spule und dem Anker des Schuingankernotors angeordnete Dämpfungseleiente 18 dienen als eigentliche Schwingungsbremse, für die Stabilisierung im mittleren Schuingungsbereich um den Null-Punkt. Wären diese Dämpfungselemente 18 nicht vorhanden, so würde die Zahnbürste lediglich in undefinierter Schwingungszahl vibrieren, jedoch keine hin- und hergehenden Bewegungen von ca. 65° ausführen.Two arranged between the coil and the armature of the sliding armature motor Damping elements 18 serve as the actual vibration brake for stabilization in the middle shear range around the zero point. Would these damping elements 18 does not exist, the toothbrush would only vibrate with an undefined number of vibrations vibrate, but do not make any back and forth movements of approx. 65 °.

Zum Ein- und Ausschalten der elektrischen Zahnbürste ist sie mit einem magnetischen Schalter 19 ausgerüstet, welcher von aussen durch Gehäuse und Ummantelung hindurch, durch einen zylindrischen Permanentmagneten, mittels eines Schiebers betätigt wird.To switch the electric toothbrush on and off, it is equipped with a magnetic switch 19 equipped, which from the outside through the housing and sheathing through, through a cylindrical permanent magnet, operated by means of a slide will.

Ein schraubenförmig gewundenes, hochflexibles Nstzzulsitungskabel 20 mit einer Knickschutztülla 21 ist in das der Zahnbürste gegenüberliegende Ende des Gehäuses eingeführt. Die Stronzuführung an die elektrischen Betriebsteile der Zahnbürste erfolgt über einen Kontaktträger 23.A helically wound, highly flexible utility cable 20 with a kink protection sleeve 21 is in the end opposite the toothbrush of the housing introduced. The power supply to the electrical operating parts of the Toothbrush takes place via a contact carrier 23.

Die eigentliche erfindungsgemässe massnahae besteht nun darin, dass die spannungsführenden Teile, wie Kabel 20, Spule 11, Kontaktträger 23, magnetschalter 19 sowie elektrische Drähte mit einer masse ummantelt sind, wie z.B. Thermo- oder Duroplast-Kunststoffen, oder Elastomer. Diese Ummantelung ist in der Zeichnung mit einer besonderen Schraffur veranschaulicht und mit dem Bezugszeichen 22 kenntlich gemacht.The actual measure according to the invention now consists in that the live parts, such as cable 20, coil 11, contact carrier 23, magnetic switch 19 and electrical wires are sheathed with a mass, such as e.g. Thermo- or thermoset plastics, or elastomer. This sheathing is in the Drawing illustrated with a special hatching and with the reference number 22 marked.

Alle nicht unter Spannung stehenden Teile, wie Spulenkern, Rotor, usw., sind nicht mit einer Ummantelung versehen.All parts that are not live, such as the coil core, rotor, etc., are not provided with a jacket.

Die genannte Ummantelung stellt einen wesentlichen Fortschritt in Bezug auf die Sicherheit bei der Verwendung elektrischer Zahnbürsten dar.Said sheathing represents a significant advance in Regarding the safety of using electric toothbrushes.
