Abstract: A filter assembly is disclosed. A filter assembly according to an aspect of the present invention may include a first housing that is fluidly connected to the outside to receive raw water and transmit generated purified water to the outside; a second housing that is screw-coupled to the filter accommodation housing and fluidly connected to the outside; and a filter structure partially accommodated in each of the filter accommodation housing and the second housing, and configured to filter the raw water to generate the purified water, wherein the second housing includes a filter support body having a height in one direction and in which a filter support space is formed to at least partially accommodate the filter structure; and a handle member coupling rib protruding radially from the outer circumference of the filter support body.

Abstract: A filter structure is disclosed. A filter structure according to an aspect of the present disclosure may include a plurality of membranes configured to selectively pass raw water through to produce purified water; a spacer disposed between the plurality of membranes configured to form a space through which the purified water flows; a tube configured to be connected to the space and the outside to form a flow path through which the purified water flows out, the plurality of membranes and the spacer being wound around the tube; and a seal assembly configured to extend along an outer perimeter of the plurality of membranes and seal the space in the outer circumferential direction, the seal assembly having a hardness different from that of the plurality of membranes.

Abstract: A filter member including a cylinder part extending in one direction, a filter hollow part which is formed inside the cylinder part to pass through along the one direction and allows the inside of the cylinder part to be in communication along the one direction, and a filtering part disposed to surround the cylinder part from radially outside and configured to filter raw water flowing through the filter hollow part.

Abstract: A composite filter and a water purifier having the composite filter are provided. The composite filter includes: a cover cap in which a first inner space is formed; a lower filter structure including a lower filter; a connection tube in which a first connection tube space and a second connection tube space are formed; a housing body in which a second inner space is formed; an upper filter structure which divides the second inner space into a first housing body space and a second housing body space and includes an upper filter; and a housing head including a first water inlet port, a first water outlet port, a second water inlet port, and a second water outlet port.

Abstract: A filter assembly includes a housing having an accommodation space formed therein so as to communicate with an external raw water supply unit and a purified water discharge unit, respectively; a filter unit formed to extend from one direction toward the other direction and accommodated in the accommodation space of the housing such that raw water supplied from the external raw water supply unit is filtered, thereby generating purified water; and a cover unit accommodated in the accommodation space of the housing so as to support the filter unit.

Abstract: A flow tube connection module and a water purifier including the same are provided. The flow tube connection module includes a housing having a coupling space in which a first flow tube and a second flow tube are connected to each other; a tube connecting member provided in the coupling space and connecting the first flow tube and the second flow tube to each other; an enlarged coupling portion provided in the housing; a coupling body coupled to the enlarged coupling portion to connect a plurality of the housings; and a separation prevention cover or a connection release member assisting the first flow tube in being connected to or separated from the tube connecting member.

Abstract: Disclosed is a water treatment apparatus that includes a head including an inlet portion into which water flows, an outlet portion from which water is discharged externally, and a connection portion connected to the inlet portion and the outlet portion, and a water treatment unit connected to the connection portion, including a plurality of water treatment sections, coupled to the head, and configured such that a portion of the water flowing into the inlet portion passes through the plurality of water treatment sections and sequentially, the remainder of the water passes through only a portion of the plurality of water treatment sections and, and the water flows to the outlet portion together.
