The present invention relates to filtering a collected sample for water analysis, and a device where filtered water is collected so that filtered water can be contained in a sample container and where the collecting rate of the sample can be controlled. The collecting device comprises at least one filter funnel part, an upper plate on which the funnel part placed, mounting device comprising a supporting rod wherein one side of the supporting rod is combined with the edge of the upper plate and a waste box fixing the supporting rod, several base container parts wherein the sample container is inserted and a outlet port is formed, and a vacuum pump connected to the vacuum connecting port by a pump tube. Accordingly, the step of transferring filtered water into the sample container can be omitted, and the collection time can be reduced by controlling the collecting rate of the sample.

What is claimed is: 1. A device for simultaneously collecting served filter paper and filtered water through the filter paper for analyzing, comprising: plurality of funnel-shaped filtering units, comprising: an influx container opened at its top and bottom to allow sampled water to pass through, a seat adapted to be removable on a lower end of the influx container in such a way that said filter paper is interposed between the influx container and the seat, with a feeding pipe vertically and downwardly extending from a lower portion of the seat, and a plug provided with a through hole in which said feeding pipe is fitted, a supporting unit, comprising: at least one supporting plate provided with a plurality of support through holes, plurality of plug support blocks of the same number as that of said support through holes, which comprises a large-diameter hollow part at an upper portion thereof and a small-diameter hollow part at a lower portion thereof, wherein said large-diameter hollow part closely receives the plug of the funnel-shaped filtering unit, and said small-diameter hollow part is inserted into said support through hole to be sealed, a vacuum release valve provided at a position of an outer surface of said plug support block so as to release an internal vacuum state of the plug support block, at least one sealing means provided on a lower surface of the supporting plate at a position around said support through holes, and at least one first attaching means provided on the lower surface of the supporting plate at a position outside said sealing means; a drain tank defining a space therein and comprising: first through holes of the same number as that of said support through holes, which is provided at a top surface of the drain tank, a second through hole provided at a predetermined position of the top surface of the drain tank, a discharging through hole formed at a predetermined position of the lower side of the drain tank, and a shut-off cock placed at said discharging through hole; a mounting means provided with supporting rods to support said supporting unit over said drain tank in such a way that said supporting unit is spaced apart from said drain tank by a predetermined distance; at least one filtered water storage unit, comprising: at least one main body of the same number as that of the support through holes, which is opened at its top and defines a space therein to hold a filtered water container for collecting filtered water, wherein said main body comprises a flange extending around an upper portion of the main body, and provided with a second attaching means to be attached to the first attaching means of said supporting unit and a drain through hole formed at a center of a bottom of the main body, and a drain tube whose one end is connected to the drain through hole of the filtered water storage unit and the other end is connected to the tube connecting through hole of the drain tank; and a vacuum pump connected the second through hole via a pump tube. 2. The device according to claim 1, wherein a plurality of guide holes are formed at predetermined positions of the supporting unit, and said supporting rod is externally threaded to engage with one of said guide holes, wherein said supporting unit is movable upward or downward relative to said drain tank along said supporting rods, and is fastened, at upper and lower surfaces of the supporting plate thereof, to a predetermined position of the supporting rod using fastening means. 3. The device according to claim 1, wherein said sealing means comprises a rubber ring. 4. The device according to claim 1, which said sealing means comprises neighboring first and second rubber rings, wherein said first rubber ring is fitted into a ring-shaped groove which is formed at the lower surface of the supporting unit, said second rubber ring is provided along an outer circumference of the first rubber ring in such a way as to be attached to the first rubber ring at a plurality of contacts provided at several positions and the diameter of said second rubber ring is larger than that of said first rubber ring. 5. The device according to claim 1, wherein said first and second attaching means comprise one or more pairs of magnets which face each other and have opposite polarities. 6. The device according to claim 1, further comprising a drain member provided at a position above the drain through hole of said filtered water storage unit, wherein said drain member is provided with a hole at its bottom and with a number of holes at its sidewall. 7. The device according to claim 1, further comprising a hollow extension part which downwardly extends from a lower edge of said filtered water storage unit, with a tube hole being formed at a predetermined position of a sidewall of said hollow extension part so that the drain tube passes through said tube hole. 8. The device according to claim 1, wherein said drain tube comprises a coiled portion at a position adjacent to the tube connecting the first through hole of said drain tank.
