Abstract

An electric toothbrush is described, comprising a vibrating brush head (20) and a main unit (6) with a vibrator motor (2) for transfer of vibrating power to the brush head (20), and also a battery (9) connected to an on/off switch (7) for operation of the vibrator motor (2). The vibrator motor (2) is not rigidly secured to the main unit (6) with help of a quick coupling (Ia), and that the vibrator motor (2) is at least partially contained in a rubber covering (5) that surrounds the main unit (6).

Description

ELECTRIC TOOTHBRUSH
The present invention relates to an electric toothbrush, comprising a vibrating brush head and a main unit with a vibrator motor for transfer of vibrating power to the brush head, and also a battery connected to an on/off switch for operation of the vibrator motor, in that the vibrator motor is not secured rigidly to the main unit with the help of a quick coupling.
From prior art, US 2003/0031979 Al, EP 460610 Al and US 2278365 can be brought forward, among others. All these publications relate to electric toothbrushes with a motor for transfer of vibrations.
It is an object of the present invention to provide an electric toothbrush which is moisture-proof and which provides improved vibrating power to the brush head of the toothbrush and reduced vibration to the toothbrush handle.
Said objects are achieved with an electric toothbrush as described in the independent claim 1, in that the vibrator motor is at least partially housed within a rubber covering that surrounds the main unit.
Alternative preferred embodiments are characterised by the dependent claims 2-6.
The rubber covering can be arranged to reduce the vibration that is transferred to the main unit from the vibrator motor. The rubber covering preferably covers most of the main unit and at least part of the vibrator motor so that a seal against moisture is provided.
The vibrator motor is preferably fitted in a motor frame which is secured to the main unit with the help of one or more quick locks that are forced into grooves or openings in a forward part of the main unit. The motor frame can comprise an internal spacer which is arranged to press against said quick lock(s) for locking of the motor frame. Furthermore, a pin can be arranged in the motor frame.
The invention shall now be described in more detail with reference to the enclosed drawings, in which
Figure 1 shows a section of a main unit of an electric toothbrush according to the invention.
Figure 2 shows a corresponding section of the main unit.
Figure 3 shows a section of the whole of the electric toothbrush according to the invention.
As can be seen from the figures, an electric toothbrush, according to the invention, comprises a main unit 6 which also functions as the handle of the toothbrush. A flexible covering is arranged around the main unit in the form of, for example, a rubber covering 5. In the main, the rubber covering surrounds most of the main unit 6. At the rear end of the toothbrush an end cover 15 is fastened to the main unit 6, where the end cover also can be covered by a rubber covering 14. The end cover 15 can house a battery 9. To safeguard against ingress of moisture, the end cover is preferably equipped with seals in the form of, for example, one or more 0-rings 13. Correspondingly, a frame 8 for the main unit can be equipped with seals in the form of, for example, one or more O-rings 11.
Two electric contacts 10, 12 are connected to an on/off switch 7 in the main unit 6 to control the supply of power to a vibrator motor 2 in a forward part of the main unit 6. The vibrator motor 2 is fitted to a motor frame 1 which is fastened to the main unit 6 with the help of a quick lock Ia in grooves or openings in the forward boring 18 in the main unit 6. To ensure that said quick lock(s) Ia does not come loose from its fastening, a spacer 4 can be arranged internally in the motor frame 1 to secure the quick locks Ia. According to the invention, an improved vibration is achieved in that the motor 2 is fitted in the motor frame 1 which is not rigidly (or not permanently) fixed to the main unit 6. The motor frame 1 is mounted so that it is at least partially covered by the rubber covering 5 that surrounds the main unit 6. The motor frame 1 can therefore be moved somewhat on the soft rubber which gives an improved vibration effect. Also provided is a dampening so that the vibration, which is transferred to the toothbrush handle, is reduced and gives a seal that prevents ingress of moisture into the unit.
As the motor frame 1 is separated from the main unit 6, this must be fitted to the main unit. This is done with the help of said quick couplings in the form of quick locks Ia that are locked in the grooves or openings. However, the quick lock can lead to that the motor frame is not secured properly and can come loose. The spacer 4 can therefore be fitted internally in the motor frame 1 so that it is nearly impossible for the quick locks to come loose, thereby releasing the motor frame fastened to the main unit. The spacer can be pushed in place after the motor frame is fitted by pressing the motor inwards which in this way presses the spacer in place. A pin 16 is provided to prevent moisture in the form of water entering the area which is formed as the motor is pressed inwards.
A brush head 20 is fitted about the motor frame 1, where seals in the form of one or more O-rings 3 are arranged between the brush head 20 and the main unit 6, and also any other seals and fastenings parts.
