The invention discloses a lampblack absorbing device used for a family range hood and easy to clean. A range hood shell is included, and the surface of a hood cover is uniformly and vertically provided with a plurality of smoke entering grooves; the surface of the inner side of the hood cover is vertically and fixedly provided with blocking strips at the two side ends of the smoke entering grooves; an oil storing box is movably clamped in a limiting groove through a limiting plate; the lower end of the surface of one side of the oil storing box is fixedly provided with an oil discharging pipe;and a threaded cover is installed at the end head position of the oil discharging pipe in a matched manner through an external thread. According to the lampblack absorbing device used for the familyrange hood and easy to clean, the blocking strips can prevent oil from being converged to the outer surface of the hood cover, and the cleanness of the outer surface of the range hood is guaranteed; when the interior of the oil storing box is full of oil, by opening the threaded cover, the oil in the oil storing box can be poured out; and when the oil storing box needs to be cleaned, the oil storing box can be fast taken down from the lower end surface of the hood cover through an annular holding handle, and the oil dirt cleaning efficiency of the range hood is facilitated.
