Foaming nozzle for sprayer

A spin spray nozzle and a foaming nozzle sprayer, said foaming nozzle adapted to be mounted to said spin spray nozzle of a sprayer, said foaming nozzle comprising a foaming cylinder through which a mist is capable of being spin-sprayed from a spray port in said spin spray nozzle at a constant spray angle in a shape of a hollow cone;

• said foaming cylinder having a generally square section including a front face defining a square mouth with mouth sides and mouth corners such that an outer circumference of said mist impinges in its substantial entirety upon said mouth sides but passes along said mouth corners without impingement.

• said foaming cylinder having a generally square section including a front face defining a square mouth with mouth sides and mouth corners, each of said mouth sides being formed with an arcuate recess between ends of the respective side;
• said foaming nozzle forcing an outer circumference of said mist to impinge in its substantial entirety upon an inner face of said square mouth at said arcuate recess but allowing said mist to pass closely along said mouth corners without impingement.

A spin spray nozzle and a foaming nozzle sprayer, said foaming nozzle adapted to be mounted to said spin spray nozzle of a sprayer, said foaming nozzle having a foaming cylinder through which a mist is capable of being spin-sprayed from a spray port in said spin spray nozzle at a constant spray angle in a shape of a hollow cone;

• said foaming cylinder having a generally rectangular section and defining at its front end a rectangular mouth with a pair of shorter sides and a pair of longer sides, each of said longer sides being formed with an arcuate recess at its front surface between both ends of said longer sides so that an outer circumference of said mist may impinge more upon inner faces of said arcuate recesses and less upon inner faces of said shorter diameter sides but pass closely along individual corners of said rectangular mouth.

A spin spray nozzle and a foaming nozzle sprayer, said foaming nozzle adapted to be mounted to said spin spray nozzle of a sprayer, said foaming nozzle having a foaming cylinder through which a mist is capable of being spin-sprayed from a spray port in said spin spray nozzle at a constant spray angle in a shape of a hollow cone;

• said foaming cylinder having a generally triangular section and defining at its front end a triangular mouth with mouth sides and mouth corners such that an outer circumference of said mist may impinge in its substantial entirety upon said mouth sides but pass closely along said mouth corners;
• said foaming cylinder being formed at said mouth sides with arcuate recesses for determining amount and range of said impingement and for diverging and emitting a cluster of said mist and foam caused by said impingement in a generally triangular sectional shape.
