Abstract

The tooth brush comprises a figurehead detachably fixed to a handle. The head contains a module with at least one pushbutton, a loudspeaker, a digital sound generator and a battery (19). When the button is pressed, a tune is generated by the sound generator for a particular period of time and played back through the loudspeaker. This design makes the toothbrush less expensive to produce and makes it easier for children to become accustomed to regular and thorough cleaning of their teeth.

Description

Eine Zahnbürste gemäss Oberbegriff des Anspruchs 1 ist aus der DE-A 3 149 233 bekannt. Im Stiel der Zahnbürste ist eine Batterie untergebracht. Am Stielende ist ein Figuren­kopf angeformt. In diesem Kopf ist ein Miniatur-Tonbandge­rät und ein Lautsprecher untergebracht. Nach der Betätigung einer Drucktaste spielt das Tonbandgerät eine Melodie während 2 bis 3 Minuten und spult hierauf selbständig zu­rück. Damit soll Kindern das Zähneputzen attraktiver ge­staltet werden, und vor allem sollen sie zum Putzen während einer ausreichenden Zeitspanne angeregt werden. Diesem Vor­schlag fehlt vor allem die praktische Realisierbarkeit. Ein Miniatur-Tonbandgerät mit den erforderlichen kleinen Abmessungen ist bisher nicht entwickelt worden. Ausserdem ist die Montage und Verkabelung der einzelnen elektroni­schen Komponenten aufwendig.A toothbrush according to the preamble of claim 1 is known from DE-A 3 149 233. A battery is housed in the handle of the toothbrush. A figure head is formed on the stem end. A miniature tape recorder and a loudspeaker are housed in this head. After pressing a pushbutton, the tape recorder plays a melody for 2 to 3 minutes and then rewinds automatically. This is intended to make children's teeth brushing more attractive, and above all to encourage them to brush for a sufficient period of time. Above all, this proposal lacks practical feasibility. A miniature tape recorder with the required small dimensions has not yet been developed. Also the assembly and wiring of the individual electronic components is complex.

Der Erfindung liegt die Aufgabe zugrunde, eine Zahnbürste gemäss Oberbegriff des Anspruchs 1 derart weiterzubilden, dass sie preiswert herstellbar ist. Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.The invention has for its object to develop a toothbrush according to the preamble of claim 1 such that it is inexpensive to manufacture. This object is achieved by the characterizing features of claim 1.

Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung erläutert. Darin zeigt:

  • Fig. 1 eine Seitenansicht der Zahnbürste, teilweise im Schnitt, und
  • Fig. 2 ein Schaltschema des elektronischen Moduls der Zahnbürste nach Fig. 1.
An exemplary embodiment of the invention is explained below with reference to the drawing. It shows:
  • Fig. 1 is a side view of the toothbrush, partly in section, and
  • FIG. 2 shows a circuit diagram of the electronic module of the toothbrush according to FIG. 1.

Die Zahnbürste nach Fig. 1 hat einen Bürstenkörper 1 und einen Griff 2, an dessen freiem Ende ein Aussengewinde 3 angeformt ist. Auf dieses ist ein Figurenkopf 4 aufge­schraubt. Im Kopf 4 ist ein elektronisches Modul 5 unterge­bracht, dessen Schaltschema in Fig. 2 dargestellt ist. Der Kopf 4 ist zweckmässig wasserdicht versiegelt.1 has a brush body 1 and a handle 2, on the free end of which an external thread 3 is formed. A figure head 4 is screwed onto this. An electronic module 5 is accommodated in the head 4, the circuit diagram of which is shown in FIG. 2. The head 4 is suitably sealed waterproof.

Das Modul 5 umfasst eine Steuereinheit 10, einen digitalen Tongenerator 11 mit drei Einzelchips 12a, 12b, 12c, in welchen je 4 Melodien von zwei bis drei Minuten Dauer gespeichert sind, sowie einen digitalen Sprachsyntetisierer 13 zur Ausgabe von Reinigungsinstruktionen in bestimmten Zeitabschnitten innerhalb der Zeitspanne, während welcher jeweils eine Melodie spielt. Der Tongenerator 11 ist mit einem Lautsprecher 14 verbunden und über eine Steuerleitung 15 an die Steuereinheit 10 angeschlossen. Die Eingabe zur Steuereinheit 10 erfolgt über 3 Leuchtdrucktasten 16a, 16b, 16c mit je einer Leuchtdiode 17a, 17b, 17c unterschiedli­cher Farbe. Steuereinheit 10 und Tongenerator 11 sind mit zwei Batterien 18, 19 gespeist, wobei die eine Batterie 18 dem Betrieb der Leuchtdioden dient, während die andere Batterie 19 die Elektronik der Steuereinheit 10 sowie den Tongenerator 11 versorgt.The module 5 comprises a control unit 10, a digital tone generator 11 with three individual chips 12a, 12b, 12c, in which are stored 4 melodies each of two to three minutes in length, and a digital speech synthesizer 13 for issuing cleaning instructions in certain time segments within the time period during which a melody is playing. The tone generator 11 is connected to a loudspeaker 14 and connected to the control unit 10 via a control line 15. The input to the control unit 10 is made via 3 illuminated pushbuttons 16a, 16b, 16c, each with a light-emitting diode 17a, 17b, 17c of different colors. Control unit 10 and tone generator 11 are supplied with two batteries 18, 19, one battery 18 serving to operate the light-emitting diodes, while the other battery 19 supplies the electronics of control unit 10 and tone generator 11.

Die Funktion der dargestellten Zahnbürste ist wie folgt:The function of the toothbrush shown is as follows:

Zu Beginn des Zähneputzens wird eine der drei Tasten 16a, 16b, 16c gedrückt, und zwar entsprechend der Tageszeiten Morgen, Mittag, Abend. Durch die betätigte Taste 16a, 16b, 16c wird über die Steuereinheit 10 der entsprechende Einzel­chip 12a, 12b, 12c mit einem zur Tageszeit passenden Melodie­repertoir angewählt, von dem eine Melodie abgerufen und ab­gespielt wird. Während der Spieldauer wird die Melodie periodisch unterbrochen zur Durchgabe von Reinigungsanwei­ sungen mittels des Sprachsyntetisierers 13, zum Beispiel "unten links aussen, unten mitte aussen usw.", beispiels­weise im Abstand von etwa 15 Sekunden. Während der Spiel­dauer der Melodie bleibt die der gedrückten Taste 16a, 16b, 16c zugeordnete Leuchtdiode 17a, 17b, 17c eingeschaltet, und der Empfang von Signalen der Tasten 16a, 16b, 16c durch die Steuereinheit 10 gesperrt.At the beginning of brushing the teeth, one of the three buttons 16a, 16b, 16c is pressed, in accordance with the times of day morning, noon, evening. By pressing the key 16a, 16b, 16c, the corresponding single chip 12a, 12b, 12c is selected via the control unit 10 with a melody repertoire suitable for the time of day, from which a melody is called up and played. During the playing time the melody is periodically interrupted to give cleaning instructions solutions by means of the speech synthesizer 13, for example "at the bottom left outside, at the bottom center outside etc.", for example at intervals of about 15 seconds. During the playing time of the melody, the light-emitting diode 17a, 17b, 17c assigned to the pressed key 16a, 16b, 16c remains switched on and the reception of signals from the keys 16a, 16b, 16c by the control unit 10 is blocked.

Der digitale Tongenerator 11 mit den Chips 12a, 12b, 12c und dem Sprachsyntetisierer 13 hat einen geringen Strombe­darf und ist sehr klein ausführbar, so dass das ganze Modul 5 als Würfel mit einer Kantenlänge von bloss 2 cm ge­baut werden kann. Das gleiche Modul 5 kann in verschieden geformte Köpfe 4 eingebaut werden, was bei geringen Kosten die Herstellung eines Sortimentes von Köpfen ermöglicht, das unterschiedliche Geschmacksrichtungen befriedigt. Da der Kopf 4 lösbar mit dem Griff 2 verbunden ist, kann er von Kindern auch zum Spielen verwendet werden. Dies ist von grossem pädagogischen Vorteil, weil damit das Kind spiele­risch an die erforderliche Zeitdauer fürs Zähneputzen ge­wöhnt wird. Ausserdem kann damit die Zahnbürste ausgewechselt werden, wenn sie verbraucht ist, ohne dass gleichzeitig auch der Figurenkopf weggeworfen werden muss.The digital tone generator 11 with the chips 12a, 12b, 12c and the speech synthesizer 13 has a low power requirement and can be made very small, so that the entire module 5 can be built as a cube with an edge length of just 2 cm. The same module 5 can be installed in differently shaped heads 4, which enables the production of an assortment of heads that satisfy different tastes at low cost. Since the head 4 is detachably connected to the handle 2, children can also use it to play. This is of great pedagogical advantage because the child is playfully accustomed to the time required for brushing teeth. It can also be used to replace the toothbrush when it is used up without having to throw away the figure head.

In den Figurenkopf 4 kann noch ein mit strichpunktierten Linien in Fig. 1 angedeutetes, durch einen Deckel 25 ab­schliessbares Reservoir 26 mit einer Spule 27 mit Zahnseide untergebracht werden. Damit ist die Zahnseide während des Zähneputzens bei Bedarf jederzeit greifbar.In the figure head 4 can be another with dash-dotted lines Lines indicated in Fig. 1, lockable by a cover 25 reservoir 26 with a coil 27 with dental floss can be accommodated. This means that the dental floss can be gripped at any time when brushing your teeth.
