Directional output type water injection pipe capable of filtering impurities

The utility model discloses a directional output type water injection pipe capable of filtering impurities, and relates to the technical field of water injection pipes. Comprising a water injection pipe body, a first connecting block and a second connecting block, fixing mechanisms are arranged on the upper side and the lower side of the water injection pipe body, a first fixing ring and a second fixing ring are sequentially installed in the water injection pipe body from left to right, and the second connecting block is installed on the left side of the first connecting block; a movable baffle is mounted on the right side of the second connecting block through a movable rod, and the situation that water flow in the water injection pipe body flows back can be prevented through movement of the movable baffle by water pressure. According to the directional output type water injection pipe capable of filtering the impurities, after water injection is finished, a second connecting block and a first connecting blo
