When it contacts the circular arc surface of the tip end portion 20d, the communication of the horizontal water passage 7c to the left side of the spool sleeve 20 is closed, and the communication portion 7i on the inlet side of the vertical water passage 7d and the right side of the spool sleeve 20 of the horizontal water passage 7c. Communicates with the part. When the faucet 1 is opened in this state, the raw water of the tap water flows from the vertical water passage 7d to the horizontal water passage 7c to the purified water inlet passage 7e and flows as shown by the dotted arrow in FIG. That is, the raw water is the purified water introduction passage 10a.
The check valve 11 is pushed up to reach the lower surface of the sealing lid 12, penetrates into the activated carbon 14 through the hole 13a of the activated carbon retainer 13, is purified at this portion, passes through the filter 5, and passes through the purified water outlet passage 7k. It flows out as purified water.

２５の摩耗に対しても有効である。When the water purification function of the cartridge 8 deteriorates, specifically, when the water purification function of the activated carbon 14 deteriorates, the cartridge 8 is replaced. The replacement is performed as follows. First, the cartridge cover 9 is removed from the cartridge receiving portion 7b. Then, the cartridge 8
Is lifted upward and removed from the cartridge receiving portion 7b. Then, a new cartridge 8 is attached to the cartridge receiving portion 7b from above. In this case, if the two mountain-shaped concave portions 10c provided on the outer peripheral side surface of the cartridge body 10 are engaged with the two convex portions 7L of the cartridge receiving portion 7b, the cartridge 8 is naturally attached to the predetermined position of the cartridge receiving portion 7b. be able to. That is, since the chevron-shaped recess 10c is provided on the outer peripheral side surface of the cartridge body 10, it can be easily confirmed by the person who replaces it. Further, since the concave portion 10c has a mountain shape with a wide entrance, even if the cartridge 8 is mounted with the cartridge receiving portion 7b slightly displaced from the accurate position, the convex portion 7L can be inserted into the concave portion 10c, and thereafter, The position of the cartridge 8 is adjusted along the convex portion 7L. Further, the upper end of the chevron-shaped recess 10c has a portion 10c 'having a width slightly wider than the width of the protrusion 7L, and the height dimension L 1 thereof is a protrusion 10d provided on the lower surface of the cartridge body 10, Since 10e is set to be larger than the dimension L 2 that overlaps the purified water inlet passage 7e and the purified water outlet passage 7k, the projections 10d and 10e are fitted in the purified water passage 7e and the purified water outlet passage 7k in the vertical direction, and the fitting property is improved. Is good. Moreover, since the convex portion 7L is integrally provided in the longitudinal direction on the inner surface of the cartridge receiving portion 7b, it has the effect of reinforcing the cartridge receiving portion 7b. Thus, according to this embodiment, the large-diameter portion 7 is formed on the body body 7 that constitutes the body portion 3.
A horizontal water passage 7c having f and a small diameter portion 7g is provided, the small diameter portion 7g is communicated with the cartridge portion 4, the large diameter portion 7f is opened outside the body main body 7, and the body main body 7 has a vertical water passage 7d having a large diameter. The spool sleeve 20 is provided so as to communicate with the portion 7f, and the spool sleeve 20 is arranged in the large diameter portion 7f. The large diameter portion 7f changes into the small diameter portion 7g without coming into contact with the communication edge portion between the vertical water passage 7i and the large diameter portion 7f. Since the spool body 21 including the O-ring 25 is movably arranged so as to selectively contact the continuous portion 7h and the spool sleeve 20 to switch the flow of the lateral water passage 7c, the O-ring 25 may be damaged. This can be eliminated and the life of the water purifier can be significantly extended. Since the O-ring 25 is wound concentrically with the spool body 21 in a single layer, the O-ring 25
Does not float above the spool body 21. Moreover, since the O-ring 25 comes into contact with the smooth arc-shaped continuous portion 7h and the spool sleeve 20, the water-sealing property is good, and the O-ring 25 is hardly deteriorated due to wear. Even if the O-ring 25 is worn for many years, the contact force necessary for water sealing can be always secured by making the moving distance of the spool body 21 large. At the time of outflow of raw water and outflow of purified water, water pressure is applied to the O-ring 25 in a direction to make the water seal stronger, so that a more reliable water seal can be achieved and it is also effective against wear of the O-ring 25.
