Abstract
A dental hygiene device includes a reservoir for storing fluid. The reservoir includes an inlet and an outlet. The dental hygiene device includes a pump having a piston driven by a motor. The pump is in fluid communication with the reservoir. The piston has a forward stroke and a backward stroke for providing a pulsating fluid flow through the outlet of the reservoir. The dental hygiene device includes a transmission connecting the pump and the motor and means to provide intermittent pauses in the pulsating fluid flow.
Claims20
A dental hygiene device comprising:
- a reservoir for storing fluid, the reservoir having an inlet and an outlet;
- a pump having a piston driven by a motor, the pump in fluid communication with the reservoir, the piston having a forward stroke and a backward stroke for providing a pulsating fluid flow through the outlet of the reservoir;
- a transmission coupled between the pump and the motor;
- and
- means to provide intermittent pauses in the pulsating fluid flow.
A dental hygiene device comprising:
- a reservoir for storing fluid, the reservoir having an inlet and an outlet;
- a pump having a piston driven by a motor, the pump in fluid communication with the reservoir, the piston having a forward stroke and a backward stroke for providing a pulsating fluid flow through the outlet of the reservoir;
- and
- a transmission coupled between the pump and the motor, the transmission including a cam coupled to the piston, the cam converting rotational movement of the motor into linear movement of the piston;
- wherein the cam moves the piston such that the forward stroke and the backward stroke are non-symmetrical to generate intermittent pauses in the pulsating fluid flow.
A dental hygiene device comprising:
- a reservoir for storing fluid, the reservoir having an inlet and an outlet;
- a pump having a piston driven by a motor, the pump in fluid communication with the reservoir, the piston having a forward stroke and a backward stroke for providing a pulsating fluid flow through the outlet of the reservoir;
- a transmission coupled between the pump and the motor;
- and
- a printed circuit board coupled to the motor to selectively energize and de-energize the motor, the printed circuit board including a preset program that generates intermittent pauses in the pulsating fluid flow.
