Description
Rotierende Zahnbürste mit elektrischem Antrieb Die Erfindung bezieht sich auf eine elektrisch angetriebene Zahnbürste, bei der die Bürstenwelle quer zum Griff gelagert ist.Rotating toothbrush with electric drive The invention relates to on an electrically powered toothbrush, in which the brush shaft transversely is mounted to the handle.
Gegenstand der Erfindung ist nun eine Zahnbürste von besonders einfacher und geschlossener Ausführung, die aber an sich leicht zerlegbar ist. Hierzu weist der Getriebekasten zwei stumpfwinklig zueinanderstehende Fortsätze auf, von denen der eine eine kegelförmige Außenfläche aufweisende Fortsatz als Lager für die durch den Bürstengriff geführte Antriebswelle und zugleich als Anschluß für den lösbaren Bürstengriff dient, während der andere Fortsatz der von dem im' Gehäusekasten vorgesehenen Kegelräderpaar zur Bürstenachse führenden Welle als Lager dient und in einem zur Aufnahme des Getriebes für die Zahnbürstenwelle dienenden Gehäuse endet.The invention now relates to a toothbrush that is particularly simple and closed design, which can easily be dismantled. To this point the gear box has two extensions at an obtuse angle to one another, of which the one having a conical outer surface extension as a bearing for the through the brush handle guided drive shaft and at the same time as a connection for the detachable Brush handle is used, while the other extension of that provided in the 'housing box Pair of bevel gears leading to the brush axis serves as a bearing and in a shaft Recording of the gear for the toothbrush shaft serving housing ends.
Auf der Zeichnung ist der Erfindungsgegenstand beispielsweise veranschaulicht, und zwar zeigt Abb. i einen Längsschnitt durch die Zahnbürste, Abb. 2 eine Seitenansicht und Abb. 3 die zugehörige Vorderansicht, während Abb. :I eine Draufsicht auf die Bürste darstellt.The subject of the invention is illustrated in the drawing, for example, namely Fig. i shows a longitudinal section through the toothbrush, Fig. 2 shows a side view and Fig. 3 the associated front view, while Fig.: I a plan view of the Brush represents.
Abb.5 ist ein Längsschnitt durch die Bürstenwelle.Fig.5 is a longitudinal section through the brush shaft.
Der Handgrif-t io des Halters ist hohl gestaltet und nimmt am inneren Ende eine verengte Hülse i i auf. Der Getriebekasten 13 hat einen abnehmbaren, kegeligen Stiel 14, der in die entsprechend kegelige Hülse i i paßt und aufschiebbar auf einem Fortsatz 15 des Getriebekastens sitzt, in dessen Bohrung die Antriebswelle 16 gelagert ist Diese trägt an ihrem inneren Ende ein Kegelrad 18. Der Getriebekasten 13 besitzt noch einen zweiten Fortsatz i g, der schräg zum vorgenannten Fortsatz 15 bzw. zum Handgriff io verläuft und eine verjüngte Hülse 20 trägt, auf der das Gehäuse 21 unter Vermittlung einer kegeligen Hülse 22 aufsteckbar sitzt. In dein Fortsatz ig ist eine Welle 23 gelagert, welche an ihrem inneren Ende ein Kegelrad 24 trägt, das mit dem Kegelrad i8 kämmt. Am äußeren Ende der Welle 23 sitzt eine Schnecke 25, die mit dem Schneckenrad 26 der in den Wänden des Gehäuses 21 gelagerten Bürstenachse 27 in Eingriff steht. Die verjüngten Enden 28 und 29 der Bürstenachse 27 ragen über die Seitenwände des Gehäuses 2i genügend hinaus, um die Bürsten 3o aufnehmen zu können. Diese sind nur schmal und werden -mittels der Naben 32, 33 auf den Achsenenden gehalten und durch Schrauben 3q., 35 gesichert.The handle-t io of the holder is designed to be hollow and takes on a narrowed sleeve ii at the inner end. The gear box 13 has a removable, tapered stem 14, the ii fits into the corresponding conical sleeve and pushed sitting on a projection 15 of the gear box is mounted the drive shaft 16 in the bore of which latter carries at its inner end a bevel gear 18. The gearbox 13 also has a second extension ig, which runs obliquely to the aforementioned extension 15 or to the handle io and carries a tapered sleeve 20, on which the housing 21 is slidably seated by means of a conical sleeve 22. In your extension ig a shaft 23 is mounted, which carries at its inner end a bevel gear 24 which meshes with the bevel gear i8. At the outer end of the shaft 23 sits a worm 25 which meshes with the worm wheel 26 of the brush shaft 27 mounted in the walls of the housing 21. The tapered ends 28 and 29 of the brush axis 27 protrude sufficiently beyond the side walls of the housing 2i to be able to accommodate the brushes 3o. These are only narrow and are held on the axle ends by means of the hubs 32, 33 and secured by screws 3q., 35.
