Abstract: An assembling structure for a filtration set includes a filter set having a plurality of filter cases, the filter cases assembled together, an assembling portion extruded on an outer surface of each filter case, the assembling portion extending from a top to a bottom of each filter case, at least one assembling plate having two ends which are respectively extruded from each side of the assembling portion and the outer surface of the corresponding filter case, the assembling plate having a positioning block at a periphery thereof, a plurality of bolts used to be inserted through the positioning block of each filter case. Wherein, a user can assemble the filter cases together via the positioning block and the bolt.

Abstract: A water purification module comprises a housing having a space longitudinally defined in the housing and extending to a top of the housing to define an opening. A purified water outlet path, a waste water outlet path and an intake path are respectively laterally defined in a lower end of the housing and respectively communicate with the space. A filter set is longitudinally received in the space form the opening. The filter set includes a hollow prior filter longitudinally received in the space, a hollow filter housing longitudinally received in the prior filter, and a hollow posterior filter longitudinally received in the filter housing. A cap is partially and complementally received in the opening for closing the housing.
