Abstract
An oral irrigator including a reservoir, a tip in fluid communication with the reservoir, a pump in fluid communication with the tip and the reservoir, where the motor drives the pump. The oral irrigator also includes a control module electrically coupled to the motor to vary an output of the motor. During a normal mode, the control module drives the motor to output a normal pulse rate, a normal flow rate, and a normal fluid pressure as the fluid exits the tip and during a massage mode, the control module drives the motor to output a massage pulse rate, a massage flow rate, and a massage fluid pressure as the fluid exits the tip. The massage pulse rate is lower than the normal pulse rate, the massage fluid pressure is lower than the normal fluid pressure, and the massage fluid pressure is lower than the normal fluid pressure.
