A portable device for supplying filtered water includes a container, a cap member, a partitioning member, a filter member, an intake tube, a piston pump unit, and a spout. The partitioning member divides an interior of the container into an outer chamber and an inner chamber. The filter member is disposed on the partitioning member, and has a first inlet communicated with the outer chamber and a first outlet communicated with the inner chamber. The intake tube is disposed in the inner chamber. The piston pump unit is mounted in the cap member, and has second inlet and outlet, and an inner cylindrical wall defining a cylindrical chamber in fluid communication with the second inlet and outlet. The second inlet is further communicated with the intake tube. The second outlet is further communicated with a passage in a piston member through which purified water is drawn up to the spout.

1. A portable device for supplying filtered water, comprising:a container including upper and lower end walls disposed to be spaced apart from each other in an axial direction, and a circumferential wall extending therebetween and confining an accommodation space, said upper end wall defining an opening to admit entry of water to be purified into said accommodation space, said opening being in fluid communication with said accommodation space; a cap member including a mounting wall extending in a transverse direction relative to the axial direction, and disposed to detachably and water-tightly cover said opening; a partitioning member disposed in said accommodation space and including a top wall having a periphery and spaced apart from said mounting wall in the axial direction, and an annular wall extending from said periphery in the axial direction and downwards to engage said lower end wall water-tightly so as to divide said accommodation space into an outer chamber, which is between said circumferential wall and said annular wall, and which is in fluid communication with said opening so as to receive the water to be purified, and an inner chamber confined by said annular wall and said top wall; a filter member disposed on said annular wall and including a first inlet disposed to be in fluid communication with said outer chamber, a first outlet disposed downstream of said first inlet and in fluid communication with said inner chamber, and a filtering element disposed downstream of said first inlet and upstream of said first outlet to purify by filtering the water passing therethrough; an intake tube disposed in said inner chamber and including a lower portion disposed proximate to said lower end wall, and in fluid communication with said inner chamber, and an upper portion extending upwardly from said lower portion in the axial direction; a piston pump unit disposed to be mounted in said cap member and including a second inlet distal to said cap member in the axial direction and in fluid communication with said upper portion, a second outlet proximate to said cap member, an inner cylindrical wall surrounding an axis parallel to the axial direction and defining a cylindrical chamber in fluid communication with said second inlet and outlet and disposed downstream of said second inlet and upstream of said second outlet, and a piston member provided with an axially extending passage which is disposed to be in fluid communication with said second outlet, said piston member being disposed in said cylindrical chamber and being movable axially relative to said inner cylindrical wall, and extending outwardly of said cap member so as to be actuated externally to lift the purified water up through said passage; and a spout disposed on said piston member and in fluid communication with said passage so that the purified water can pass therethrough.
