Foaming nozzle for sprayer

摘要

A foaming nozzle mounted in front of a spray nozzle of a sprayer so that a liquid detergent may be sprayed in a foamed state onto a window glass or tile for cleaning. The foaming nozzle has its mouth shaped so that a mixed cluster of the mist and foam from the foaming nozzle is injected in a band, elliptical, rectangular or triangular shape and at a wide angle. A predetermined relationship between a spray port and the foaming nozzle allows the mist spin-injected at a high swirling speed to be partially mixed with the foam. The foam is formed by the impingement of the mist upon an inner face of the mouth of the foaming nozzle. The mixture may be injected at a wide angle. The foaming nozzle can be composed of first and second nozzles wherein the second foaming nozzle is of a circular cylinder and hingedly mounted to the first foaming cylinder. The user can selectively inject either a mist-foam mixed cluster having the band section or a foam cluster having a circular section.
