The invention discloses a domestic building material mixer. The domestic building material mixer comprises a mixing cavity. The domestic building material mixer is characterized in that a lifting mainshaft base is fixedly connected with the center of the bottom of the mixing cavity, auxiliary rotating bases are fixedly connected with the periphery of the lifting main shaft base, a lifting gas cylinder is fixedly connected with the upper portion of the lifting main shaft base, a main mixing threaded shaft is movably connected with the upper portion of the lifting gas cylinder, a driving motoris fixedly connected with each auxiliary rotating base, an auxiliary rotating shaft is fixedly connected with the upper portion of each driving motor in a threads manner, a heating disk is fixedly connected with the inner wall of the bottom of the mixing cavity in an annular manner, a filter screen is fixedly connected with one side of the upper portion of the mixing cavity, and a rechargeable battery cavity is fixedly connected with the surface of the outer side of the mixing cavity. The domestic building material mixer is simple in structure, convenient to install, stable in structure, longin service life, flexible to remove and small in occupied space; the uniformity of mixing is improved because the main and auxiliary rotation mixing manner is adopted; the efficiency is improved, cleaning is convenient, resources and time are saved, and constraint caused by electric wires is reduced.
