Rotatable filter
A rotatable filter includes a base unit, a rotating unit and an external unit. The base unit includes a seat having a through hole, and a container disposed on the seat, corresponding in position to the through hole and having a drainage space. The rotating unit is disposed on the base unit and includes a rotating disc mounted on the seat and having a rotating part that is rotatable relative to the seat, a converging seat connected to the rotating part and having a collecting space that is in fluid communication with the drainage space, a plurality of guiding pipes extending into the converging seat, and a plurality of valve seats respectively disposed on the guiding pipes. The external unit is connected to the rotating unit and includes a rotating cover disposed above the seat, and a plurality of filtering modules disposed on the rotating cover.
1 . A rotatable filter, comprising:
a base unit that includes a seat having a through hole, and a container disposed on said seat, corresponding in position to said through hole and having a drainage space,
a rotating unit that is disposed on said base unit, and that includes a rotating disc mounted on said seat and having a rotating part which is rotatable relative to said seat, a converging seat connected to said rotating part of said rotating disc and having a collecting space which is in fluid communication with said drainage space, a plurality of guiding pipes extending into said converging seat and in fluid communication with said collecting space, and a plurality of valve seats respectively disposed on said guiding pipes, and
an external unit that is connected to said rotating unit, and that includes a rotating cover disposed above said seat, rotatable together with said rotating part about a central axis, and having an accommodating space for accommodating said rotating unit, and a plurality of filtering modules disposed on said rotating cover; wherein said rotating cover includes a plurality of receiving slots that surround the central axis, that are spaced apart from each other and that are respectively in fluid communication with said valve seats, and said filtering modules are detachably and respectively disposed on said receiving slots.
2 . The rotatable filter as claimed in claim 1 , wherein a total number of said plurality of receiving slots of said rotating cover is twelve, and a total number of said plurality of filtering modules of said external unit is twelve.
3 . The rotatable filter as claimed in claim 1 , wherein a total number of said plurality of receiving slots of said rotating cover is six, and a total number of said plurality of filtering modules of said external unit is six.
4 . The rotatable filter as claimed in claim 1 , wherein each of said filtering modules of said external unit includes an adapter that is detachably inserted into a corresponding one of said valve seats via the respective one of said receiving slots, and a filtering cup that is detachably connected to said adapter.
5 . The rotatable filter as claimed in claim 1 , wherein said base unit further includes a drain pipe that is in fluid communication with said drainage space.
6 . The rotatable filter as claimed in claim 1 , wherein each of said valve seats of said rotating unit includes a valve body, and a knob that is connected to said valve body and that is operable to open and close a path of fluid in said valve body.
7 . The rotatable filter as claimed in claim 6 , wherein said rotating cover of said external unit has a circular top surface and a sidewall that extends downward from an outer periphery of said top surface.
8 . The rotatable filter as claimed in claim 7 , wherein said knobs of said valve seats of said rotating unit are equally spaced apart from each other and are disposed on a side of said sidewall of said rotating cover that is opposite to said accommodating space.
