That is, the clock from the clock generator 71 composed of a crystal oscillator or the like is counted by the first counter 72, and the count number is calculated by the first comparator 73 and the maximum number of days when the water treatment device 1 is normally used. In comparison, when the former becomes larger than the latter, a signal is issued to the OR circuit 74. Further, the flowmeter 75 installed in the raw water supply passage 8 or the like makes the amount of water used as a pulse signal, which is counted by the second counter 76, and the second comparator 77 counts the number of water and the predetermined water treatment layer. When compared with the latter, the signal is sent to the former OR circuit 74.

Further, while the clock from the clock generator 71 is also counted by the third counter 78, when running water is detected by the flow meter 75, the count is cleared and the water treatment device is processed. 1 counts the number of days not continuously used, and when the number of non-use days exceeds the predetermined number of days in the third comparator 79, a signal is issued to the OR circuit 74. When any one of the above signals is input to the OR circuit 74, a sound, light, etc. alarm is issued by the alarm generating device 81 to notify that the water treatment material S has reached the replacement time. The cartridge replacement forecasting device 70 is attached to the bottom of the base 1.

With the above configuration, when the water treatment device 1 is installed at a predetermined place of use, the switch 80 is turned on to turn on the power source (not shown), and the cartridge replacement timing notification device 70 is operated. Then, when a water tap (not shown) is opened, raw water (tap water) flows from the raw water supply port 10 provided on the base 1 into the pretreatment filter charging section 6, passes through the filter 53 and the passage port 47. The large particle suspension is removed into the barrel 46 and passes through the magnetic device 60. As described above, the magnetic device 60 is formed by alternately arranging spherical and disk-shaped first and second permanent magnets 66 and 67. Since the magnet spacing is small, a large magnetic field is formed. Further, since the flow resistance is comparatively small due to the existence of the spherical permanent magnet 66, the raw water is activated and then passes between the cover 30 and the cartridge 20 and passes through the opening 24 from the upper side to the lower side in the cartridge 20. After flowing down, it is discharged from the discharge pipe through the water conduit 25 and the magnetic device 60 provided in the cap 35.
