Composite filter and water purifier having same

A composite filter, comprising:

• a cover cap in which a first inner space is formed therein;
• a lower filter structure disposed in the first internal space and including a lower filter;
• a connection tube extending in length, having a first connection tube space and a second connection tube space formed therein extending in the longitudinal direction, having a lower end coupling to the lower filter structure, thereby, together with the lower filter structure, partitioning the first inner space into a first cover cap space and a second cover cap space;
• a housing body in which a second inner space with an upper side opening to the outside is formed and the cover cap, the lower filter structure, and the connection tube are disposed in the second inner space;
• an upper filter structure comprising an upper filter, the upper filter structure being disposed above the lower filter structure, coupled to the connection tube, and having a lower end coupled to the cover cap, thereby partitioning a space above the cover cap among the second inner space into a first housing body space and a second housing body space;
• a housing head coupled to the upper side of the housing body, having a first water inlet space, a first water outlet space, a second water inlet space, and a second water outlet space formed therein, and having a first water inlet port connected to the first water inlet space, a first water outlet port connected to the first water outlet space, a second water inlet port connected to the second water inlet space, and a second water outlet port connected to the second water outlet space;
• a first flow path formed such that through which first raw water introduced into the first water inlet port passes through the first water inlet space, the first housing body space, the upper filter, the second housing body space, and the first water outlet space, and then is discharged through the first water outlet port into first purified water;
• and
• a second flow path formed such that through which second raw water introduced into the second water inlet port passes through the second water inlet space, the first connection tube space, the first cover cap space, the lower filter, the second cover cap space, the second connection tube space, and the second water outlet space, and then is discharged through the second water outlet port into second purified water.
