BRIEF SUMMARY
TECHNICAL FIELD OF THE INVENTION
This invention relates to mouth cleaning devices and, more particularly, to a mouth cleaning device which allows one to selectively perform tooth brushing or gum cleaning by mounting either a brush member or nozzle member to a single main body.
BACKGROUND OF THE INVENTION
While one may cleanse one's mouth by tooth brushing and gum cleaning one has been unable to perform both tooth brushing and gum cleaning simultaneously unless respective equipment for both are provided. Conventionally, they have been prepared separately for reasons that an integral combination of the tooth brushing and gum cleaning equipment has rendered the device bulky, to deteriorate with usage and so on.
With a view to solving this problem, a personal mouth cleaning device has been suggested in a Japanese Patent Publication No. 16548/1971 wherein the same main body is used with the brush member and nozzle member interchanged with each other. The above-mentioned device however, employs an hydraulically operated motor as a driving source for the brush member which motor is defective in that the brush member will not operate when the liquid is exhausted or its amount is reduced.
OBJECTS OF THE INVENTION
A first object of the present invention is, therefore, to provide a mouth cleaning device wherein a hand held gripping part of the mouth cleaning device is reduced in size.
A second object of the present invention is to provide a mouth cleaning device wherein a brush member and nozzle member are made interchangeable with each other with respect to the same main body so that, when the brush member is mounted to a driving rod, the brush member will be reciprocally turned to perform the tooth brushing and, when the nozzle member is mounted to the driving rod, water will be jetted out of the nozzle member to perform the gum cleaning and gum massaging.
A third object of the present invention is to provide a mouth cleaning device wherein the foregoing operations can be selectively made through a change-over switch.
A fourth object of the present invention is to provide a mouth cleaning device wherein a change-over switch can be automatically switched over by means of the brush and nozzle members.
Other objects of the present invention will be apparent by the following explanations with reference to the illustrated embodiments.
SUMMARY OF THE INVENTION
In the present invention, a driving means providing a reciprocal turning force to a brush member and a water feeding path which leads water from a water feeding means of a separate body to a nozzle member is built in a hollow case which is made to be a hand held gripping part of a mouth cleaning device, whereby the gripping part is minimized in size and the conventional problems are solved.
More particularly, in the mouth cleaning device according to the present invention a hollow case which forms a gripping part in the present invention is provided with an electric motor, a converting means which converts a rotary motion of said electric motor to a reciprocal turning motion, a driving rod reciprocally turned by said converting means, a water receiving port to which a hose connected to a water feeding means is connected and a water feeding path communicating with said water receiving port. The water feeding path is formed within the driving rod and a mount for a brush member and nozzle member is formed on said driving rod so that the brush and nozzle members can be interchangeably mounted.
Further in the present invention, a change-over switch for selectively changing over a source current feeding the driving device for the brush member and water feeding device for the nozzle member is selectively actuated by the mounting of the brush and nozzle members.
