Systems and methods for controlling an oral irrigator

An oral irrigator (100) system comprising:

• an irrigator tip (103), the irrigator tip comprising:
• a handle portion (106);
• a nozzle (109);
• a channel (112) in fluid communication with the handle portion (106) and the nozzle (109);
• and,
• an actuator (115), the actuator arranged to at least partially alter a flow (142) of a fluid (145) through the channel (112);
• a reservoir (151) containing the fluid (145), the reservoir in fluid communication with a pump (154);
• one or more sensors (357, 157) arranged to detect a change in the flow (142);
• and,
• a controller (172) configured to:
• determine whether a key sensor indicator is above, below, or at a threshold;
• and
• if the key sensor indicator is above a threshold, change an operational level of the oral irrigator (100) to a standby mode;
• or if the key sensor indicator is at or below the threshold, remain at a current operational level;
• or if the key sensor indicator is below the threshold, and the current operational level of the oral irrigator (100) is standby mode, change the operational level of the oral irrigator (100) to a preset intensity operational level previously set before entering standby mode.
