Abstract:
1. A valve cartridge assembly comprising: a valve cartridge and a transmission device, wherein a recess is formed on the top of the valve cartridge, the recess being formed with a radially inwardly protruding profile, wherein said transmission device includes a transmission member, the transmission member being formed with a radially outwardly protruding profile and further having elastic protruding ribs, the transmission member being at least partially positioned in the recess of the valve cartridge, wherein a releasable engagement is formed between the elastic protruding ribs and an inner wall of the recess, wherein the elastic protruding ribs are engaged to the inner wall of the recess so as to have a first transmission relationship between the transmission member and the valve cartridge, the first transmission relationship being configured to allow the transmission member to drive the valve cartridge to rotate axially, wherein the radially inwardly protruding profile and the radially outwardly protruding profile cooperate with each other so as to have a second transmission relationship between the transmission member and the valve cartridge, the second transmission relationship being configured to allow the transmission member to drive the valve cartridge to carry out a squeeze movement, wherein the squeeze movement enables the valve cartridge to have a moving component at least in an axial direction, and enables the elastic protruding ribs to be disengaged from the inner wall of the recess such that the transmission member is rotatable in the valve cartridge, allowing the valve cartridge assembly to switch between the first transmission relationship and the second transmission relationship, and wherein when the movement in the first transmission relationship is ended, the relationship between the transmission member and the valve cartridge switches from the first transmission relationship to the second transmission relationship.
