Liquid sprayers

A liquid sprayer includes a casing having a flow-through channel composed of sequentially joined inlet portion formed as a converging tube, a cylindrical portion and an outlet portion formed as a conical diffuser. A length of cylindrical portion is not less than a radius thereof. A cone angle of the diffuser forming the outlet portion of the flow-through channel is greater than a cone angle of the converging tube forming the inlet portion of the same channel. Alternatively, the converging tube forming the inlet portion of the flow-through channel is made conoid-shaped. Implementation of the liquid sprayer allows steady-state fine-dispersed liquid flow to be generated at the minimal energy consumption.
