<p>A device for treating and filtering water, of the type which comprises at least two cups (11) for containing a filtration cartridge (12, 13), each cup (11) being fixed reversibly to a corresponding head (14a, 14b) for the intake and discharge of the water from the cup (11), each head (14a, 14b) having a first water intake port (15a, 15b) which is open onto an annular duct (16) which allows the water to descend into the cup (11), outside the filtration cartridge (12, 13), and a second discharge port (17a, 17b), which the water reaches by means of a central riser opening (18), after passing radially through the cartridge (12, 13) towards its interior; below the body of each head (14a, 14b) there is an annular portion (19) which is internally threaded complementarily for a corresponding thread (20) provided around the mouth of the corresponding cartridge supporting cup (11). The heads (14a, 14b) are provided as a single body (21), with the discharge port (17a) of a first head (14a) which is extended without discontinuity into the intake port (15b) of the following head (14b), the intake port (15a) of the first head (14a) and the discharge port (17b) of the last head (14b) being preset with connecting means for unions with corresponding pipes respectively for introducing water and discharging water from the device (10).</p> |
