Abstract: An anti-electric shock power socket comprising a main housing body; a negative electrode holder, installed in the main housing body and connected to a negative electrode of a power supply for holding a negative prong of an inserted plug; a positive electrode holder, installed in the main housing body for holding a positive prong of an inserted plug, wherein the positive electrode holder is provided with an overlapping spring plate which can be pushed outward by the inserted positive prong; a positive conducting plate installed in the main housing body and connected to the positive electrode of the power supply. Only when the plug is correctly inserted, the overlapping spring in the positive electrode holder is driven so it overlaps with the positive conducting plate to be closed-circuited with the positive electrode so as to supply power to an electric appliance.

Abstract: A scrubber for removing soluble materials from harmful gaseous effluents with high efficiency and safety is disclosed. By using twice mixes of the scrubbing liquid and the harmful gaseous effluent, the scrubber meets the standards of environment protection. The scrubber of this invention also prevents the problems of factory safety presenting in the conventional fume scrubber. Owing to the high efficiency of the mixing of the harmful gaseous effluent and the scrubbing liquid, the production facilities or processing units need not stop operating once the supply of the scrubbing liquid terminates.
