Abstract: A structure for automatic cleaning of a water quality purification cartridge includes a water quality purification cartridge having a water purification flow path and a raw water flow path. An upstream side surface of the water quality purification cartridge is cleaned by raw water flowing through the raw water flow path.

Abstract: A shower head for purifying water includes a filter cartridge positioned within in a holding part, a purified water flow path passing through a purification material and a raw water flow path not passing through the purification material. A flow path switching valve switching between the purified and raw water flow paths is incorporated in a head part. A delivery flow switching valve positioned downstream of the flow path switching valve switches between a straight delivery port and a shower delivery port. The valves are controlled independently of each other. A germicidal ceramic and/or sintered magnetic body is installed in the flow path between the valves.

Abstract: A shower head with water purification function includes a water quality purification cartridge including an outer diameter thereof being smaller than an inner diameter of a holding part, an end portion at a downstream side provided with a portion fitting into a cartridge accepting portion of the holding part, a water quality purification material having a central hole which opens at an end portion at a downstream side; in case of water quality purification material seated in a water quality purification cartridge and a water quality purification cartridge fitted into a cartridge accepting portion housed in the holding part, there are constructed an upstream side flow path being formed along an upstream side surface of the water quality purification cartridge, a water purification flow path penetrating the water quality purification cartridge, and a raw water flow path which does not penetrate the water quality purification material; an each downstream side flow path of the water purification flow path and the

Abstract: It is an object of the present invention to provide a shower head with water purification function capable of easing restrictions on a shape, structure and storage capacity of a water quality switching valve, and also providing a well-balanced shape and structure for easier handling. A water quality purification cartridge is built in a holding part, and a purified water flow path passing through the water quality purification cartridge and a raw water flow path not passing through the water quality purification cartridge are formed by the incorporation of this water quality purification cartridge.
