Atomizer nozzle assemble

Claim 1

An atomizer nozzle assembly including a nozzle body (1) having a plurality of nozzle heads (10) arranged in equally spaced relation around a longitudinal axis (X - X) thereof, each of the nozzle heads (10) having a mounting hole (14), a nozzle tip (11) mounted in said each mounting hole (14) and having a liquid passage hole (23) opening at the front end thereof, an air jet passage (18) defined between said each mounting hole (14) and the outer periphery of said each nozzle tip (11), the nozzle tips (11) being so arranged that their respective longitudinal axes (Y - Y) converge at a point (A) on said longitudinal axis (X - X), whereby as currents of compressed air are caused to jet out toward the point (A) on said longitudinal axis (X - X) passing through the air jet passages (18), they suck liquid thereinto through the respective front end openings of the liquid passage holes (23) to form jet streams of a gas-liquid mixture so that the jet streams impinge against one another at the point (A) on said longitudinal axis (X - X), thereby producing an ultra fine mist of liquid, characterizing in that the liquid passage hole (23) of said each nozzle tip (11) extending along the longitudinal axis (Y - Y) of the nozzle tip (11) and having its front end opening (24) centrally formed in a front end fare (33) of the nozzle tip (11), an outer periphery of a forward end portion of said each nozzle tip (11) being tapered, angle of taper (α) thereof being 16° - 24°.
