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.

First claim

1 . A flow tube connection module comprising:
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.

2 . The flow tube connection module of claim 1 , wherein the first flow tube is provided as an inflow tube and an outflow tube provided in a head portion of a water filter.

3 . The flow tube connection module of claim 2 , wherein the tube connecting member comprises a first flow channel connection port to which the first flow tube is connected, and a second flow channel connection port to which the second flow tube is connected.

4 . The flow tube connection module of claim 3 , wherein the tube connecting member comprises connection caps installed in the first flow channel connection port and the second flow channel connection port, to fix the first flow tube and the second flow tube, respectively.

5 . The flow tube connection module of claim 4 , further comprising a close contact member inserted into at least one of the connection caps to be in close contact with the first flow tube or the second flow tube.

6 . The flow tube connection module of claim 5 , wherein the connection cap comprises an inclined portion configured to be inclined in a length direction of the first flow tube or the second flow tube, and
the close contact member is moved along the inclined portion when the first flow tube or the second flow tube moves, to be in close contact with the first flow tube or the second flow tube.

7 . The flow tube connection module of claim 6 , wherein the close contact member comprises:
a body portion inserted into the connection cap to be in close contact with the first flow tube or the second flow tube, and to be in contact with the inclined portion, and a head portion extended from the body portion outwardly of the connection cap, to be exposed externally of the connection cap.

8 . The flow tube connection module of claim 7 , wherein the body portion comprises a separation prevention projection protruding toward the inclined portion to move along the inclined portion, and a plurality of separation grooves formed in a circumferential direction thereof, and is configured to be elastically transformed in a center direction when the connection cap presses the body portion in the center direction.

9 . The flow tube connection module of claim 8 , wherein the head portion comprises a stop protrusion protruding outwardly of the connection cap.

10 . The flow tube connection module of claim 4 , wherein the separation prevention cover is provided on the housing to move, and is configured to extend in an outer circumferential direction of the water filter, in such a manner that the tube connecting member fixed to the inflow tube and the outflow tube is maintained.

11 . The flow tube connection module of claim 10 , wherein the separation prevention cover has one side contacting a rear portion of the head portion, and the other side fixed to the housing, such that movement of the head portion in a direction away from the housing is limited.

12 . The flow tube connection module of claim 11 , wherein the separation prevention cover comprises a cover body including a receiving space receiving the head portion, and a movement protrusion protruding from the cover body to a predetermined height and connected to the housing.

13 . The flow tube connection module of claim 12 , wherein the cover body further comprises a fixing portion extending from an inner side thereof toward the inflow tube and the outflow tube, to fix the inflow tube and the outflow tube.

14 . The flow tube connection module of claim 5 , wherein the connection release member comprises a half-groove notch portion configured to have one side extending in a direction toward the head portion included in the close contact member, and the other side fixed to the housing, to be in contact with the head portion and thus prevent movement of the close contact member.

15 . The flow tube connection module of claim 1 , wherein the housing comprises a movement groove continuously formed in a movement direction of the separation prevention cover or the connection release member.

16 . The flow tube connection module of claim 15 , wherein the separation prevention cover or the connection release member comprises a movement protrusion inserted into the movement groove formed to be concave.

17 . The flow tube connection module of claim 1 , wherein the enlarged coupling portion comprises a coupling groove into which the coupling body is inserted.

18 . The flow tube connection module of claim 17 , wherein the coupling groove is provided in a continuously concave form formed to have a predetermined length in a direction toward the second flow tube.

19 . The flow tube connection module of claim 17 , wherein the coupling body comprises a coupling protrusion inserted into the coupling groove.

20 . A water purifier comprising:
a body part configured to allow for an inflow of water thereinto; a plurality of water filters disposed inside the body part, configured to filter the water flowing thereinto, and each including an inflow tube and an outflow tube; and the flow tube connection module of claim 1 , disposed in the body part, and associated with the inflow tube and the outflow tube to connect the plurality of water filters to one another.
