Abstract
An irrigating device including a reservoir for storing fluid, a tip fluidly connected to the reservoir, and a pump operative to draw fluid from the reservoir and propel the fluid to the tip. The irrigating device further includes at least one reed valve positioned to regulate fluid between at least one of an inlet port or an exhaust port of the pump.
Claims18
(canceled)
An oral irrigating device comprising
- a reservoir for storing fluid;
- a housing connected to the reservoir;
- a tip fluidly connected to the reservoir;
- a pump positioned within the housing and operative to draw the fluid from the reservoir and propel the fluid to the tip, the pump comprising an inlet port and an exhaust port;
- a motor positioned within the housing;
- a drive mechanism positioned within the housing, operably connected to and between the motor and the pump, and configured to drive the pump;
- and
- a control structure operably connected to the motor and configured to receive a user input;
- wherein
- a motion of the drive mechanism varies in response to a user input to the control structure;
- and
- an output pressure and a pulsation rate of fluid exiting the tip is variable in response to the motion of the drive mechanism.
The oral irrigating device 2, wherein in response to the user input the control structure varies a voltage applied to the motor.
A method for irrigating an oral cavity of a user comprising:
- receiving an input from a user through a first control button or a second control button on an oral irrigation device;
- if the first control button is selected, providing a first voltage to a motor causing a first fluid pressure output by a pump;
- and
- if the second control button is selected, providing a second voltage to a motor causing a second fluid pressure output by the pump.
A handheld oral irrigator comprising
- a reservoir defining a fluid cavity;
- a pump in fluid communication with the reservoir;
- a motor connected to the pump and configured to selectively activate the pump;
- a battery connected to the motor;
- and
- a control structure connected to the battery, wherein the control structure selectively varies a voltage from the battery provided to the motor to vary at least one output characteristic of the motor.
