The cartridge-type water purifier body having a built-in adsorbent such as a porous hollow fiber membrane and the like is detachably assembled, and by switching the flow path switching valve in conjunction with the operation of a switching lever or the like. The tap water from the faucet is switched to purified water passing through the water purifier main body, straight raw water, shower of raw water, and the like.

By the way, in the conventional tap-type water purifier, as shown in FIGS. 3 and 4, for example, a raw water supply port 14 of the faucet connection body 12 to the water purifier main body 15 and a housing of the water purifier main body 15 are provided. Raw water inlet 1 formed in
Ring 13 for watertight sealing between
Is attached to the raw water supply port 14 of the faucet connection body 12, and the water ring elastic ring 13 is attached to the faucet connection body 12.
Was to be used semi-permanently. Further, in the conventional tap-type water purifier, the housing of the water purifier body 15 is not actually designed to suppress the growth of mold and various germs. Note that in FIG.
Shows a faucet to which the faucet connection body 12 is attached.

For this reason, the elastic ring 13 used semi-permanently together with the faucet connection body 12 is cracked or deformed due to deterioration over time due to long-term use, and water leakage from the elastic ring 13 is caused. It was easy for problems such as

When the water purifier body 15 is attached to the faucet connection body 12 for replacement, the faucet connection body 12
If the raw water remaining in the inner water passage adheres to the vicinity of the contact surface between the elastic ring 13 and the raw water supply port 14, the elastic ring 13 is contaminated by the raw water, and is liable to cause corrosion and deterioration. In some cases, water leakage from the elastic ring 13 may occur.

Further, the housing of the water purifier body 15 has
No measures are taken to control the growth of mold and germs,
Due to the splash water generated during the water work adhering to the surface of the housing, molds and various germs propagate from the portion where the splash water adheres, and the surface of the housing of the water purifier body 15 is contaminated. There was also a problem such as.

[0009]
