Spray head for a paint sprayer, and paint sprayer

A spray head for a paint sprayer, for generating a paint jet,

• wherein the spray head comprises an air gate, an air cap and a needle,
• wherein the air cap is arranged downstream from the air gate in an air flow direction,
• wherein the needle is arranged upstream from the air gate in the air flow direction,
• wherein the air gate comprises a centrally arranged paint outlet opening and air outlet openings,
• wherein a paint nozzle is formed by the paint outlet opening and, with the needle, forms a needle valve,
• wherein the air cap has a centrally arranged through-opening of elongate cross section for the passage of the paint jet or of the paint nozzle and for the passage of a stream of sheathing air surrounding the paint jet or the paint nozzle,
• wherein the through-opening is oriented with a substantially longitudinal axis and a substantially horizontal axis, each of the substantially longitudinal axis and the substantially horizontal axis being transverse to a central axis of the spray head running in the air flow direction,
• wherein the air cap comprises two air horns, each air horn protruding past the through-opening in the air flow direction and being defined spaced apart from each other on opposite sides of the through-opening along the substantially horizontal axis,
• wherein the air horns each comprise at least one horn air channel directed toward the paint jet emerging from the paint outlet opening,
• wherein each at least one horn air channel receives air via at least one of the air outlet openings of the air gate,
• wherein the air cap comprises two curtain air channels, each curtain air channel having an outlet arranged between the air horns, the outlets being defined opposite each other on opposite sides of the through-opening along the substantially horizontal axis,
• wherein the outlets of each of the curtain air channels have an outlet length substantially parallel to the substantially longitudinal axis of between 70% and 90% of a length of the through-opening of the air cap, and
• wherein the outlets of each of the curtain air channels have an outlet width substantially parallel to the substantially horizontal axis of at most 50% of the respective outlet length of the outlet of each of the curtain air channels.
