AIR-INTAKE AND FOCUSED-TYPE SPRAYER APPARATUS

摘要

Disclosed is an air-intake and focused-type sprayer apparatus comprising: a convergence chamber having along the axial direction thereof a large end and a small end of varying sizes, an inner wall provided with a gradual transition between the large end and the small end, at least two water inlet paths in communication with the large end of the convergence chamber, where all of the water inlet paths converge within the convergence chamber towards an water discharging direction of the convergence chamber, at least one air intake passage in communication with the convergence chamber from the external open space, and a rectifier opening in communication with the small end of the convergence chamber and provided with a throat for allowing water flow to form a liquid seal. The cross-section of the throat is one to three times greater in size than the maximum cross-section of the water inlet path; the rectifier opening gradually increases outwards in the cross-section size thereof from the throat. In tandem with the throat capable of forming the liquid seal, and with the air intake passage, the convergence chamber having the gradual transition between the large and small ends allows water flow to produce convergence and air intake effects of increased conspicuousness in the convergence chamber, thus augmenting collision between air and water flow, and allowing for improved effect and increased range of the spraying water particles discharged.
