Abstract
A dental hygiene (10) has a housing (12) that provides a manually deployable handle for the device and that houses a motor (14) that drives both a brush agitating drive mechanism (16) and a liquid dispensing pump mechanism (18). The housing (12) has a tool mount (20) that interchangably mounts in operable relation with the drive mechanism and with the pump mechanism any one of a dental brush tool (22) and a dental spray tool (24). The brush tool and the drive mechanism preferably are arranged to agitatingly drive two sets of brush elements (26) and (28) oppositely, preferably with back and forth rotation of individual brush tufts.
Claims5
Dental appliance apparatus comprising
- A. manually deployable housing means,
- B. power means mounted within said housing means, said power means including means for actuating brush elements of a dental brush tool and including means for controlling delivery of liquid to a dental tool,
- C. a first tool mount on said housing means for removably and replaceably mounting any one of a dental brush tool and a dental spray tool to said housing means,
- D. said dental brush tool having actuatable brush elements and having a second tool mount that couples removably and replaceably with said first tool mount for mounting said brush tool to said housing means operably coupled with said actuating means for actuating said brush elements for movement relative to the second tool mount, and
- E. said dental spray tool having a liquid-discharging spray element and having a third tool mount that couples removably and replaceably with said first tool mount for mounting said spray tool to said housing means alternative to said brush tool and operably coupled with said controlling means for the delivery to said spray element of liquid supplied to said power means.
In dental appliance apparatus having a manually deployable housing and having a motor element within said housing for providing reciprocating drive to drive actuable brush elements of a dental brush tool, the improvement comprising
- A. first and second side-by-side reciprocating members coupled with said motor element, for receiving out-of-phase reciprocating motion,
- B. means for operatively coupling said reciprocating members with said brush elements of said dental tool for actuating said brush elements,
- C. liquid pump means mounted within said housing and arranged for receiving liquid from a supply thereof, said pump means having at least first and second pumping chambers, each of which is slideably fitted with a pumping piston, and having valved fluid passages for the delivery of the received liquid to said chambers and for the further delivery of pumped liquid from said chambers for application to said dental tool,
- D. means operatively connecting said pump means with said motor element for reciprocating said piston elements relative to said chamber elements, and
- E. means operatively connecting said reciprocating members with said motor element for the driving reciprocation both of said pump means and of said reciprocating members in common by said motor element.
