  The type in which the water purifier of Reference 1 is directly attached to the faucet of the water discharge pipe is compact, but the cartridge filled with the purifying agent is small, so that the life of the cartridge is short, and compared to a separately installed water purifier having a long cartridge life. The disadvantage is that the cartridge must be replaced frequently.

  Further, in the case where the water purifier of Reference 2 is separately installed, the cartridge replacement time of the purifying agent is long, but it is necessary to provide a bypass pipe, an operation switch, a branch portion, and the like, and there is a problem that connection of the pipe becomes complicated. .

  Therefore, the present invention provides a water purifier connector that can connect a water purifier to a water faucet simply by attaching the water purifier to the water faucet pipe of the water faucet.

  The present invention relates to a water purifier connecting device that connects to a water discharge pipe of a water faucet and connects a water purifier to a water faucet by connecting a water discharge head to a side opposite to a connection portion with the water discharge pipe. A raw water supply hose that communicates with the raw water passage and supplies raw water to the water purifier is connected to a tubular connector main body having a raw water passage formed therein, through which the raw water from the water discharge pipe communicates with the water pipe. Raw water supply pipe, and a purified water supply pipe connected to a purified water outflow hose of the water purifier are provided, and the purified water supply pipe is provided independently of the raw water passage along the axis of the connecting member main body. It is characterized by being connected to the purified water channel.
