By separating the cartridge 4, the water purification cartridge 160 can be housed or replaced inside the grip 110.

A rotatable flow switching valve 170 having an axis parallel to an axis extending perpendicularly and horizontally to the axis of the grip 110 is fitted in the head 120. A cylindrical operating member assembly 125 protrudes from the side surface of the head 120, one end of the flow path switching valve 170 protrudes from the operation member assembly 125, and the operation unit 130 is assembled. The flow path switching valve 170 housed inside the section 120 can be rotated around an axis.

[0013] In the holding portion 110 accommodating the water purification cartridge 160, the flow path 116 on the outer peripheral side of the water purification cartridge 160 is used as a part of the raw water flow path, and the water purification material 161 of the water purification cartridge 160 is used as the water purification material 161. The formed central space 162 is used as a part of a purified water flow path. Thereby, in the case of the purified water discharge, the mixed water flowing into the grip portion 110 flows from the flow path 116 on the outer peripheral side of the water purification cartridge 160 to the water purification cartridge 160.
The water quality purifying material 161 is passed to purify the water quality, and then flows out to the central space 162. In the case of discharging raw water,
The water passes through the flow path 116 on the outer peripheral side of the water purification cartridge 160 and flows out to the head 120 side.

The water purification cartridge 160 comprises a water purification material 161 formed in a cylindrical shape with a central space 162 provided concentrically with the central axis, and filters 163, 164 made of non-woven fabric, sponge, mesh or the like on the downstream side.
