The invention provides an anti-backflow water filter for a drainpipe, belongs to the technical field of fittings of sewers, and particularly to a water filter at a mouth of a sewer. The object of the invention is to provide an anti-backflow water filter for a drainpipe, the anti-backflow water filter is composed of an elastic funnel made from silica gel and a flushing cap water seal member, sewage can be prevented from flowing back, the deodorant effect is good, and the anti-backflow water filter can be used even if one of the parts breaks down, and is convenient to maintain. The adopted technical scheme is that a body is a cylinder having an upper opening, a filter cover is movably mounted to the opening, the lower portion of the body is fixedly connected with a flushing cap water seal member, the flushing cap water seal member comprises a U-shaped channel and a turnover cap, an opening at one end of the U-shaped channel is connected with the body in a sealing mode, and the other opening of the U-shaped channel is hinged with a matching turnover cap, the middle portion in the body is provided with a protruding ring by cooperation of internal and external steps and its own weight, the bottom of the protruding ring is sleeved with the elastic funnel made from silica gel, the outlet in the lower portion of the elastic funnel is flat and elastically sealed to form a closed deodorant structure.
