Abstract
Abstract A tooth cleaning apparatus having two housing portions is disclosed. Between bot housing portions, which are connected with one another by means of a snap connection, a rubber elastic ring is fixedly clamped. This ring is inserted into a groove at a support element, to which the drive motor is attached as well as a printed circuit board. A magnetically actuable switch is mounted to this circuit board is for turning-on turning-off the motor. This switch is activated by means of a magnetic element, which is secured at an actuation element displaceably mounted at the housing outer surface. The vibration dampening ring prevents transmission of vibrations emanating from the motor to the housing and at the same time serves as sealing element.

Claim 1
Independent Claim
100 words
An electrical tooth cleaning apparatus, comprising: a housing composed of at least two mutually interconnected housing portions; a drive motor arranged in said housing; a support for a tooth brush arranged to be driven by said drive motor; a vibration dampening element fixedly clamped between both of said housing portions; said drive motor is mounted in said housing and is fixed in position by means of said vibration dampening element; a snap connection for interconnecting both of said housing portions with one another; and said snap connection is constituted by cooperating connecting elements provided on each of said housing portions.
Claim 2
Dependent Claim
100 words
An electrical tooth cleaning apparatus, comprising: a housing composed of at least two mutually interconnected housing portions; a drive motor arranged in said housing; a support for a tooth brush arranged to be driven by said drive motor; a vibration dampening element fixedly clamped between both of said housing portions; said drive motor is mounted in said housing and is fixed in position by means of said vibration dampening element; a snap connection for interconnecting both of said housing portions with one another; and said snap connection is constituted by cooperating connecting elements provided on each of said housing portions.
Claim 3
Dependent Claim
20 words
The tooth cleaning apparatus according to claim 1, wherein the vibration dampening element is further constructed as a sealing element.
Claim 4
Dependent Claim
20 words
The tooth cleaning apparatus according to claim 1, wherein the vibration dampening element is a ring formed of elastic material.
Claim 5
Dependent Claim
32 words
The tooth cleaning apparatus according to claim 3, further including a support element mounted in said housing to which the motor is secured, and at which the vibration dampening element is mounted.
Claim 6
Dependent Claim
28 words
The tooth cleaning apparatus according to claim 4, further including a groove at the circumference of said support element into which said ring-shaped vibration dampening element is inserted.
Claim 7
Dependent Claim
14 words
The tooth cleaning apparatus according to claim 3, wherein said ring is an O-ring.
Claim 8
Dependent Claim
22 words
The tooth cleaning apparatus according to claim 4, further including printed circuit board means and gear means attached to said support element.
Claim 9
Dependent Claim
35 words
The tooth cleaning apparatus according to claim 1 wherein said cooperating connecting elements are formed by cams provided at a housing portion and latching noses provided at the other housing portion which engage said cams.
Claim 10
Dependent Claim
89 words
The tooth cleaning apparatus according to claim 1, further including a magnetically actuatable switch mounted internally of the housing for switching-on and switching-off the drive motor, a magnetic element arranged at an actuation element displaceably guided at the outside of the housing for opening and closing said switch, two stops arranged at the housing outer surface or at the actuation element for the releasable arresting of the actuation element in its end positions, said stops being capable of being travelled-over, and a latching element which coacts with such stops.
Claim 11
Dependent Claim
18 words
The tooth cleaning apparatus according to claim 9, wherein the stops and/or the latching element are elastically deformable.
Claim 12
Dependent Claim
55 words
The tooth cleaning apparatus according to one of the claims 9 or 10, wherein the stops are formed by a web arranged at one housing portion and extending in a displacement direction of the actuation element, which web engages in both end positions of the actuation element behind latching elements mounted at the actuation element.
Claim 13
Dependent Claim
25 words
The tooth cleaning apparatus according to claims 9 or 10, wherein the actuation element is connected by means of a snap connection with the housing.
Claim 14
Dependent Claim
37 words
The tooth cleaning apparatus according to claim 12, wherein the actuation element has two side walls for engaging below a guide rail mounted at one housing portion and is guided in lengthwise direction by said guide rail.
Claim 15
Dependent Claim
23 words
The tooth cleaning apparatus according to claim 13, wherein each guide rail serves as a fixed displacement limiting stop for the actuation element.
Claim 16
Dependent Claim
29 words
The tooth cleaning apparatus according to claims 4 or 9, characterized by the features that the switch is mounted upon a printed circuit board secured at the support element.
