a water treatment unit ( 300 ) including first and second water treatment sections ( 321 , 322 ) coupled to the head ( 200 ), and configured such that a portion of the water flowing into the inlet portion ( 211 ) passes through the first and second water treatment sections ( 321 , 322 ) sequentially, the remainder of the water passes through only a portion of the first and second water treatment sections ( 321 , 322 ), and the water flows to the outlet portion ( 212 ) together,
wherein the head ( 200 ) comprises:
a head body ( 210 ) including the inlet portion ( 211 ), the outlet portion ( 212 ), and the connection portion ( 213 ); and
a flow guide portion ( 220 ) guiding the water flowing into the inlet portion ( 211 ) to flow into the water treatment unit ( 300 ), and guiding the water treated by the water treatment unit ( 300 ) to flow into the outlet portion ( 212 ), and

wherein the flow guide portion ( 220 ) includes:
a passage forming member ( 221 ) including an inflow passage ( 221 a ) having an open lower portion connected to an inflow portion ( 311 ) included in the water treatment unit ( 300 ) and connected to the inlet portion ( 211 ), and an outflow passage ( 221 b ) connected to the outlet portion ( 212 ) and the connection portion ( 213 ); and
an opening/closing member ( 222 ) rotatably provided on the passage forming member ( 221 ) and including a plurality of opening/closing apertures ( 222 a , 222 b ) formed therein to open or close a plurality of first inflow apertures ( 311 a ) or a plurality of second inflow apertures ( 311 b ) formed in the inflow portion ( 311 ) according to a rotating location of the opening/closing member ( 222 ).

2. The water treatment apparatus of claim 1 , wherein the plurality of first inflow apertures ( 311 a ) and the plurality of second inflow apertures ( 311 b ) are spaced apart from each other by a predetermined interval, are formed in a circumference of a virtual circle on the inflow portion ( 311 ), and have diameters of which the sizes are decreased in a single direction; and
the plurality of opening/closing apertures ( 222 a , 222 b ) have slots with different lengths, are spaced apart from each other by a predetermined interval and are formed in the opening/closing member ( 222 ) in locations corresponding to locations of the plurality of first inflow apertures ( 311 a ) and the plurality of second inflow apertures ( 311 b ).

3. The water treatment apparatus of claim 1 wherein the flow guide portion ( 220 ) further comprises:
a connection member ( 223 ) connected to the opening/closing member ( 222 ) to block an open upper portion of the passage forming member ( 221 ); and
a gripping member ( 224 ) connected to the connection member ( 223 ).

4. The water treatment apparatus of claim 3 , wherein the opening/closing member ( 222 ) and the connection member ( 223 ) have an elastic member ( 225 ) provided therebetween.

5. The water treatment apparatus of claim 1 , wherein the water treatment unit ( 300 ) includes:
an inlet/outlet member ( 310 ) having the inflow portion ( 311 ) into which water flows from the head ( 200 ) and an outflow portion ( 312 ) through which water is discharged to the head ( 200 ); and
a housing ( 320 ) connected to the inlet/outlet member ( 310 ), including the first water treatment section ( 321 ) and the second water treatment section ( 322 ), and configured such that a portion of the water flowing into the inflow portion ( 311 ) passes through the first and second water treatment sections ( 321 , 322 ) sequentially, the remainder of the water passes through only the second water treatment section ( 322 ), and the water flows together to the outflow portion ( 312 ).

6. The water treatment apparatus of claim 5 , wherein the second water treatment section ( 322 ) is located above the first water treatment section ( 321 ); and a portion of the water flowing into the inflow portion ( 311 ) flows into a lower portion of the housing ( 320 ) and then passes through the first and second water treatment sections ( 321 , 322 ) sequentially, and the remainder of the water passes through only the second water treatment section ( 322 ).

7. The water treatment apparatus of claim 6 , wherein the first water treatment section ( 321 ) includes a functional substance or an ion-exchange resin, and the second water treatment section ( 322 ) includes carbon particles.

8. The water treatment apparatus of claim 6 , wherein the inflow portion ( 311 ) includes a plurality of first inflow apertures ( 311 a ) and a plurality of second inflow apertures ( 311 b ), and the outflow portion ( 312 ) includes a plurality of outflow apertures ( 312 a ).

9. The water treatment apparatus of claim 8 , wherein the housing ( 320 ) further comprises:
a first guide member ( 323 ) including a first passage ( 323 a ) connected to the plurality of first inflow apertures ( 311 a ) so that water passing through the plurality of first inflow apertures ( 311 a ) flows into the first passage ( 323 a );
