Abstract
A hair removing apparatus has hair removing device (13) for at least partially removing hair projecting from a skin; a liquid channel (16) leading to a liquid outlet (12); a pump (5) for causing liquid displacement through the liquid channel to the liquid outlet; a motor (1) coupled to the hair removing device (13); a transmission coupled to the motor (1) and to the pump (5); and a control structure (4,7-9) operable between at least a first and a second operating condition for dispensing liquid at different rates. The control structure (4,7-9) is arranged for controlling amounts of movement transmitted by the transmission to the pump such that, in the first and second operating conditions, different amounts of movement are transmitted by the transmission to the pump.
Claims10
An electric personal care device for dispensing a liquid, comprising:
- a housing having a liquid outlet;
- a liquid channel leading to the liquid outlet;
- a pump for causing liquid displacement through the liquid channel to the liquid outlet;
- a motor operatively coupled to the device for driving movement of at least a movable part of the device;
- and
- a control structure having an inclined surface operable between at least a first position on the inclined surface and a second position on the inclined surface;
- and
- a rod, arranged between the motor and the control structure, wherein the control structure is arranged between the rod and a resilient wall of the pump communicating with or part of the liquid channel, wherein the rod is movable by the motor between a pushing position and a return position, in which pushing position the rod keeps the resilient wall displaced inwardly compared with a position of the resilient wall when the rod is in its return position, and wherein the inclined surface of the control structure is arranged to control the displacement of the resilient wall between the pushing and return positions of the rod such that, different amounts of displacement of the resilient wall occurs between the first and second positions on the inclined surface.
An electric personal care device for dispensing a liquid, comprising:
- a housing having a liquid outlet;
- a liquid channel leading to the liquid outlet;
- a pump for causing liquid displacement through the liquid channel to the liquid outlet;
- a motor operatively coupled to the device for driving movement of at least a movable part of the device;
- a transmission coupled to the motor to be driven thereby and coupled to the pump for imparting movement to at least a movable part of the pump while in an ‘on’ condition, thereby causing pumping action by the pump;
- and a control structure operable between at least a first and a second operating condition for dispensing liquid at different rates;
- wherein the control structure is arranged for controlling amounts of movement transmitted by the transmission to at least the movable part of the pump such that, in the first and second operating conditions, different amounts of movement are transmitted by the transmission to at least the movable part of the pump,
- wherein the pump has a resilient wall at least partially enclosing an internal space communicating with or part of the liquid channel;
- the transmission further comprises a pushing member which is at least partially movable between a pushing position and a return position, in which pushing position the pushing member keeps the resilient wall displaced inwardly with respect to the internal space compared with a position of the resilient wall when the pushing member is in its return position;
- wherein the control structure is arranged to control the displacement of the resilient wall between the positions associated with the pushing and return positions of the pushing member such that, in said first and second operating conditions, different amounts of displacement of the resilient wall between the positions associated with the pushing and return positions of the pushing member are caused;
- and
- wherein said control structure comprises a control member of which a portion is located between said pushing member and said resilient wall, said portion between said pushing member and said resilient wall having a different thickness in a direction from the pushing member to the resilient wall.
