System appliance and cartridge for personal body care

An appliance for body care, comprising a treatment device for carrying out a treatment on the body of a user, and an interface for coupling a cartridge to the appliance, which cartridge has a space for storing an auxiliary fluid, wherein:

• the appliance includes a blocking device adapted to block at least one function of the appliance,
• the blocking device is adapted to unblock said function when a cartridge having a key is coupled to the appliance, and
• the blocking device comprises a magnetic detector or an electromagnetic detector for detecting a magnetic key or electromagnetic key on a cartridge coupled to the appliance, and a control unit coupled to the detector.

An appliance for body care, comprising a treatment device for carrying out a treatment on the body of a user, and an interface for coupling a cartridge to the appliance, which cartridge has a space for storing an auxiliary fluid, wherein:

• the appliance includes a blocking device adapted to block at least one function of the appliance,
• the blocking device is adapted to unblock said function when a cartridge having a key is coupled to the appliance, and
• the blocking device comprises at least two electrodes for engagement with contact surfaces of a cartridge coupled to the appliance, and a control unit coupled to the electrodes.

A cartridge comprising

• a space for the storage of an auxiliary fluid intended for personal body care in conjunction with a body-care treatment,
• an interface for coupling the cartridge to an appliance adapted to carry out said treatment, wherein the cartridge has a key for unblocking a function of the appliance when the cartridge is coupled to the appliance, said key comprising an optical key.

A cartridge comprising

• a space for the storage of an auxiliary fluid intended for personal body care in conjunction with a body-care treatment,
• an interface for coupling the cartridge to an appliance adapted to carry out said treatment,
• wherein the cartridge has a key for unblocking a function of the appliance when the cartridge is coupled to the appliance, said key comprising a magnetic key or an electromagnetic key.

An appliance for body care, comprising a treatment device for carrying out a treatment on the body of a user, and an interface for coupling a cartridge to the appliance, which cartridge comprises a key with projections, a diaphragm pump, a space for storing an auxiliary fluid, and an outlet for applying the auxiliary fluid,

• wherein:
• the appliance includes an actuating mechanism which is coupled to the pump and a blocking device adapted to block the actuation of the pump by the actuating mechanism,
• the blocking device comprising projections which, when the cartridge having a key with projections is coupled to the appliance, cooperate with the projections of the key, the dimensions of the projections of the cartridge and key determining whether the actuating mechanism is blocked or unblocked.
