Abstract: An oral care refill head (300), the oral care refill head (300) may be detachably coupled to a handle (200). The handle (200) may include a stem (250) that is received within a connection cavity (326) of the oral care refill head (300). The stem (250) and the connection cavity (326) may have specific geometries and structures to ensure an adequate coupling therebetween. An oral care implement (100), the oral care implement (100) have a pressure sensing assembly, excessive pressure applied onto the oral care refill head (300) will cause the motor (140) and a motor chassis (401) to rock. As the motor chassis (401) rocks, a contact element (456) thereon will actuate a pressure actuator element (455). In response, a control unit (150) may initiate generation of a user perceptible signal to inform the user of the excess pressure.

Abstract: An oral irrigator (100) for cleaning a user's oral cavity and a method of using the oral irrigator (100) are disclosed. The oral irrigator (100) may have a reservoir (111) for storing a fluid and a tip (120) or nozzle that is in fluid communication with the reservoir (111) so that the fluid can be pumped from the reservoir (111) to the tip (120). The oral irrigator (100) may also include a pump (153) for pumping the fluid, a motor (152) for driving the pump (153), and a control module (154) for controlling the operation of the motor (152) in accordance with a mode selected by a user. The modes may include a continuous spray mode whereby the fluid is only pumped from the reservoir (111) to the tip (120) while a user is actuating an activation member (112). The modes may also include automatic spray modes whereby the fluid is pumped in accordance with pre-defined treatment protocols.

Abstract: An oral irrigator tip (120) for an oral irrigator (100). The oral irrigator tip (120) may be configured for coupling to an oral irrigator (100) for purposes of irrigating a users teeth, gums, and interproximal regions. The oral irrigator tip (120) contains a dispensing member (150) in its interior, and the dispensing member (150) leaches an oral care agent during use as a fluid such as water flows past the dispensing member (150) within the interior of the oral irrigator tip (120). The oral irrigator tip (120) may be a monolithic structure. The dispensing member (150) may be non-removable from the interior of the oral irrigator tip (120), such that upon depletion of the oral care agent from the dispensing member (150) the entire oral irrigator tip (120) is replaced. The dispensing member (150) may be in the shape of a torus such that the dispensing member (150) does not impede the flow of the fluid through the oral irrigator tip (120).

Abstract: An oral care implement handle (200) having a gripping portion (210) and an oral care refill head (300) that is detachably coupled thereto. The oral care implement handle (200) may include the gripping portion (210) and a rocker unit (400) which includes a stem (250), a motor (224), and a motor chassis (410). The rocker unit (400) may be pivotably mounted within the gripping portion (210) so that upon pressure being applied an oral care refill head (300) which is coupled to the stem (250) that exceeds a pressure threshold, the rocker unit (400) may be altered from a normal position to an excessive pressure position. When in the excessive pressure position, the rocker unit (400) may actuate an actuator element (265) of a control unit (260) to initiate generation of a user perceptible signal.
