摘要： A device for forming a liquid treatment apparatus includes a main part; and a receiving part including a cavity for receiving a connecting head of a replaceable liquid treatment cartridge having at least one port in liquid communication with an interior of the liquid treatment cartridge such that the at least one port(s) of the connecting head are in sealed liquid communication with corresponding ports of the receiving part. The receiving part is journalled for movement between a first and a second position with respect to the main part whilst the connecting head is inserted in the cavity. The head is insertable into and retractable from the cavity in the first position. The liquid treatment cartridge is lockable to the device by at least moving the receiving part with the inserted connecting head into the second position.

摘要： A device for forming at least part of a head part of a liquid treatment apparatus is arranged to receive a connecting head of a replaceable liquid treatment cartridge and includes at least one ratio-setting valve. The ratio-setting valve is provided with at least two first ports, each placeable in essentially sealed liquid communication with respective cartridge ports of a connecting head of a replaceable liquid treatment cartridge inserted into the device, and with at least one second port. The ratio-setting valve includes at least one movable regulating part for setting a volumetric flow rate ratio between a first flow of liquid between a first of the first ports and the at least one second port and a second flow of liquid between a second of the first ports and the at least one second port at any of a plurality of values.
