Water discharge head equipped with purification function, water purification cartridge, and water faucet device
[Problem] To provide a water purification cartridge which is capable of preventing false recognition of a discharge of water and has excellent reliability. [Solution] This water discharge head 8 has: a restriction member RG1 which can be transitioned between a first state J1 and a second state J2, and which restricts switching from raw water to purified water by a switching mechanism in the first state, and permits switching from raw water to purified water by the switching mechanism in the second state; a water purification cartridge provided with a restriction release unit DR1 which transitions the restriction member RG1 from the first state J1 to the second state J2, and a water-impermeable tip closed outer surface 196; and a water purification cartridge mounting part. The tip closed outer surface 196 faces a raw water flow passage WG. The restriction member RG1 is arranged in a purified water flow passage WJ.
