た多孔質の中空フイルタ中に収容してある。 In this known example, a switching cylinder having a flange-like valve plate at the upper end is provided inside a cylindrical body to be attached to a faucet so as to be movable in the vertical direction, and the lower part of the switching cylinder is moved downward from the center of the lower surface of the cylindrical body. When water is rapidly discharged from a large number of small holes, the switching tube is raised and its upper end is closed, and the water flowing into the cylindrical body from the faucet is discharged through the small holes on the outer periphery of the lower surface of the main body. Also, when discharging purified water, the switching tube is lowered, and the valve plate prevents water from flowing toward the small hole on the outer periphery, allowing it to flow through the inside of the switching tube. For this purpose, a filter material such as activated carbon is housed in a porous hollow filter that is detachably suspended from the lower end of the switching tube.

して極めて容易に装備できる。<Effects of the invention> The water purifier of the present invention, like the conventional example described above, raises the switching cylinder with a valve plate to flow water outside in a shower shape, and conversely lowers the switching cylinder to switch. Water flows out through the hollow part of the cylinder, but a cartridge filled with granular activated carbon is housed inside the main body, and when the switching cylinder is lowered, water flows into the inside of this cartridge, Since the flow is made to flow outward in a rod shape through the annular water sprinkler, there is no need to attach a filter containing a filter material such as activated carbon to the lower end of the switching tube that protrudes downward from the bottom surface of the annular water sprayer, which obstructs work at the sink. Never.
In addition, unscrew the annular water spray body from the cylindrical outer shell of the cartridge, remove the old one with reduced activated carbon capacity from the cylindrical outer shell, and insert the new one into the inner surface of the cylindrical outer shell. It can be installed very easily by simply dropping it into the inside surrounded by the ribs and then screwing the annular water sprayer again so that it can be positioned concentrically and vertically inside the main body.

流出させることができる。 Furthermore, the inside of the cartridge filled with granular activated carbon has an outer circumferential part where the water that has entered the main body from the faucet flows upward due to the cylindrical wall, and an inner circumferential part where the water that has flowed upward on the outer circumferential part turns around and flows downward. Therefore, even if the height of the cartridge is low, water contacts the granular activated carbon over a length approximately twice the height of the cartridge. Therefore, it is possible to lower the height of the cartridge, which in turn lowers the height of the water purifier body, and allows the water treated with activated carbon to flow out from the inside of the switching tube in a rod shape.
