TUBING CONJUNCTION STRUCTUER FOR WATER PURIFYING MULTI-FILTER

摘要

The present invention relates to a connection hose coupling structure of a multi-staged water purifying filter. In the present invention, fitting that is performed with a relatively large amount of components is not used, but the inlet and outlet of the multi-staged water purifying filter is coupled with a connection hose only by means of an elbow pipe and a connection cap, so that the number of components can be reduced and points of leakage can be minimized. The connection hose coupling structure of the multi-staged water purifying filter according to an embodiment of the present invention couples a connection hose with the inlet or outlet of the multi-staged water purifying filter for a water purifier in which multiple water purifying filters are serially disposed in an installation frame. The connection hose coupling structure of a multi-staged water purifying filter comprises: an elbow pipe that has one end equipped with a first coupling part inserted in the inlet or outlet in order to be watertightly coupled and has the other end equipped with a second coupling part bent vertically in order to be inserted in and coupled with the connection hose; and a connection cap that enables the connection hose to be watertightly coupled with the second coupling part of the elbow pipe by pressurizing the connection hose onto the second coupling part so as to surround the edge of the second coupling part.
