Nozzle geometry dictates spray pattern, coverage area and user experience.
Cone nozzles (45–60°) generate a hollow cone ideal for hair roots or plant undersides; droplet size 100–130 µm. Fan nozzles (80–110°) create a flat sheet perfect for glass or car panels; edge taper reduces centre striping.
Foam nozzles mix air via venturi, expanding 1 ml liquid into 8 ml foam for vertical cling on toilet bowls; requires 28/400 neck minimum for air vent. Stream nozzles concentrate 1.2 ml into a 2 mm jet for spot weed control or BBQ grease targeting; reach 1.5 m but offer minimal surface coverage.
Quick-change modular heads allow brands to ship one trigger sprayer body with four colour-coded tips, cutting SKU complexity 40 %. Always match nozzle orifice to viscosity: <1 mm for watery cleaners, 1.2 mm for gels, 1.5 mm for degreasers.
