The invention discloses a portable
water sample collecting suction filter. An upper frame and a lower frame of the collecting suction filter are connected, the lower frame, a base and a shell are connected, the shell covers the upper frame and the lower frame completely, a suction filtering
system comprises a suction filtering head, an upper sleeve, a clamping buckle, a lower sleeve, liquid collecting bottles, supporting boards, a
rotating hinge, a sliding groove, an air suction
pipe, filtering membrane, a
gasket, a battery, a vacuum
air pump and a clamping ring, and an operation display
system comprises a display panel, an operation button, a circuit board and a printing
system. A tester uses connection between a
smart phone and the suction filter, through a printer, labels of
water sample drawing time and location information are obtained, and the liquid collection bottles on different specifications are placed in the sleeves. By adopting the portable
water sample collecting suctionfilter, the step of pouring filter liquid in liquid collection bottles according to a traditional suction filter and the step of manual water sample adding according to a traditional suction filter can be omitted, water samples and impurities are prevented from being mixed, operation is simple, and carrying is convenient.
