The utility model provides a component structure of a photocopier, particularly an efficient liquid spray evaporator used for a developer of an ammoniacal diazo copier. The evaporator is provided with an electrical heating tube, a liquid inlet pipe, an evaporation pipe and pipe plugs; the electrical heating tube is arranged in the evaporator; the pipe plugs are arranged on the pipe openings at two ends of the evaporator; the liquid inlet pipe is vertically arranged at the middle part of the evaporator; and a plurality of liquid spray holes, which are formed in a crossed manner, are uniformly formed at two ends of the evaporator on the side wall near the electrical heating tube. The utility model has the beneficial effects that the preheating time of the ammoniacal diazo copier is greatly shortened; the problem that the surface of a whole drawing paper cannot be developed uniformly is solved; the power consumption of the developer is reduced; the ammonia water not only is reduced in use amount, but also can be
