It describes the simple structure of the brush part (20) of an electric toothbrush, in which the bristle carrier plate (11) perform a pendulum motion about a longitudinal axis and the bristles (15) themselves a pendulum rotational movement about their vertical axis. The necessary gear arrangements within the brush part (20) consist essentially of a transverse pin (8), which is guided in an oblique gate (10) and which is connected to a push rod (7). The push rod (7) is toothed at its front end and engages gears (16) of the bristle carrier (14).
The The invention relates to a brush part for a with a handpiece and an adjoining brush part formed electrical Toothbrush, the brush part one in a longitudinal direction reciprocating sliding movement displaceable push rod and at the front end of the brush part a bristle carrier plate which has a longitudinal direction of the brush part extending longitudinal axis is rotatably supported and by a arranged in the brush part gear in one around the longitudinal axis pendulum movement is displaceable, and being on the bristle carrier plate Bristle carrier around their perpendicular to the bristle carrier plate aligned vertical axis are rotatably mounted by means of the push rod can be displaced in a swinging rotary motion about the vertical axis.
Such a brush part or a toothbrush with such a brush part is in the WO 03/084427 A1 described. The highlight of this toothbrush is that the bristle carrier plate makes a pendulum movement about a longitudinal axis of the toothbrush, while at the same time the bristles or the bristle carrier perform a pendulum motion about its vertical axis.
The Invention is based on the object to represent a brush part, the said movements from a projecting from the handle of the toothbrush Drive shaft, one in the longitudinal direction performs reciprocating motion, deduce. The necessary Funds should be as simple as possible be constructed and easy to assemble.
to solution of the problem, the invention provides that the bristle carrier plate a rear sleeve-like Extension has, in the front end of the brush part about the longitudinal axis rotatable and longitudinal Is pushed horizontally, and that the extension has a passage has, through which the push rod is passed, wherein the push rod in the region of the extension deviating from a circular shape Has cross section and the passage in the extension of a similar and the same size Cross section has.
These Arrangement leaves easy to assemble, as the bristle carrier plate with its extension only in the brush part must be used. Since the push rod one around the longitudinal axis oscillating movement, becomes the bristle carrier plate because of the adapted cross sections of push rod and passage taken along and leads also a swinging movement.
The Push rod leads continue a reciprocating motion. This movement can be used to the bristle carrier drive.
To the invention provides that the push rod from the extension to protrudes forward and on the protruding ends on both sides each having a toothing that the bristle carrier at their lower ends are each provided with a gear and that on Each side of the push rod a gear in the respective teeth engaging.
In order to adjacent bristle carrier to increase move the cleaning effect in opposite directions, it is provided that arranged on each side of the push rod at least two bristle carrier with gears are, wherein the gear of a bristle carrier with the gear of the other bristle carrier in Intervention is, in turn, with the teeth of the push rod engaged.
Around from a reciprocating movement of the drive shaft a just the same reciprocating movement of the push rod, the one of superimposed on a swinging movement is to produce, it is provided that the push rod at its rear end is provided with a transverse pin, which in with respect to the brush part in an oblique to the longitudinal axis extending slanted scenery, and that the cross pin as well in a direction transverse to the longitudinal axis extending in a connecting rod formed transverse link running, wherein the connecting rod is provided to communicate with one of the Handpiece coupling protruding drive rod.
Around to realize a simple structure is a sleeve-like carrier part provided in which the slanted backdrop and storage for the extension are formed, and in an outer shell of the brush part forming shell is immovably arranged and fixed.
The Invention further provides that at the front end of the jacket an upwardly open shell is formed, in which the bristle carrier plate is located and arranged there such that the bristles on the bristle carrier protrude from the shell.
The The invention further relates to an electric toothbrush a handpiece and a brush part, the brush part realized as described above.
in the The following is based on an embodiment the invention closer explained become. In addition shows
1 in a perspective view of the internal structure of a brush part,
2 a longitudinal section through the 1 .
3 a perspective view of a brush part, the arrangement according to 1 receives
4 the detailed representation of a bundle of bristles in a bristle carrier,
5 a detailed view of the push rod.
First, on the 1 and 2 Referenced. These show the internal structure of a brush part. This consists of a sleeve-like carrier part 1 , in the rear end of a connecting rod 2 slides. At her from the carrier part 1 rearward protruding end can be the connecting rod 2 with a drive rod 3 by means of a snap connection 4 be releasably coupled. The front end of the connecting rod 2 has a cylindrical cavity 5 in which a cylindrical slider 6 that with a push rod 7 connected, slides.
With the slider 6 is a cross pin 8th connected to either side of the slider 6 protrudes and in a trained as a slot transverse link 9 in the connecting rod 2 and a sloping slanted backdrop 10 in the carrier part 1 extends. As a result, a transmission is formed, which causes a reciprocating movement of the drive rod 3 in one of two movements, namely a reciprocating motion and a pendulum motion, composite movement of the push rod 7 translated.
When caused by an electric motor in a handpiece reciprocating movement of the drive rod 3 becomes the connecting rod 2 taken. Because the cross pin 8th in the transverse frame 9 can not perform any longitudinal movement, performs the slider 6 a similar movement on the push rod 7 is transmitted. At the same time they take care of the slanted scenery 10 reaching in the ends of the cross pin 8th for being on the slider 6 In addition, a pendulum motion is transmitted. The inclination of the slanted backdrop 10 indicates the relationship between the reciprocating motion and the oscillating motion.
At the front end of the carrier part 1 is a bristle carrier plate 11 arranged. This has a rear, cylindrical extension 12 with a passage 13 , It is rotatable in the front end of the carrier part 1 plugged in. It leads into the carrier part 1 exclusively a rotary motion. By appropriate mechanisms, a reciprocating motion is prevented.
The cross section of the push rod 7 in the area of the passage 13 is rectangular and flat, deviating from a round cross-section. The passage 13 itself has the appropriate shape, so the pendulum movement of the push rod 7 directly on the bristle carrier plate 11 is transmitted.
In the bristle carrier plate 11 are several, with bristle tufts 15 provided bristle carrier 14 , which at their lower end each with a gear 16 are provided. A detailed representation of such a bristle carrier 14 is located in the 3 ,
The bristle carrier 14 are arranged in two rows, with each second bristle carrier in each row 14 slightly closer to the center, so that the respective gear 16 in a toothing 17 at the push rod 7 can intervene. The gears 16 the bristle carrier 14 , which are set outward, grab the gears 16 the aforementioned bristle carrier 14 so that they perform an opposite movement to them.
A detail of the push rod 7 with a front toothing 17 is located in 5 ,
The 3 shows the arrangement according to 1 and 2 in a brush part 20 , This consists of a coat 21 , at the front end of an open-topped shell 22 is arranged, in which the bristle carrier plate 11 is located, with the bristle tufts 15 upwards out of the shell 22 protrude.
The inner cross section of the jacket 21 is the outer cross section of the carrier part 1 adjusted so that this firmly in the mantle 21 can be used.
The bristle carrier plate 11 abuts the front side of the shell 22 on, causing the bristle carrier plate 11 is limited to a purely oscillating movement. If necessary, a pen 23 the outer end of the bristle carrier plate 11 support.
The coat 22 is with locking devices 24 provided to connect to a hand part of a toothbrush, not shown here. At the same time a connection between the drive rod 3 and the connecting rod 2 produced.
