Abstract: An airless spraying equipment includes a spray tip guard, a spray tip configured to be inserted into the spray tip guard perpendicularly to the axis of the spray tip guard, a pre-atomizing component, and a tip atomizing component. The pre-atomizing component and the tip atomizing component are connected to each other sequentially along the channel axis, in a fluid stream direction. The pre-atomizing component further includes a feeding channel, a pre-atomization channel, and at least two pre-atomization regulating channels. The feeding channel, the pre-atomization channel, and the at least two pre-atomization regulating channel are coaxial hollow channels sequentially defined and connected along the channel axis inside the pre-atomizing component.

Abstract: A low-pressure spraying equipment for atomizing a working fluid at a low-pressure, includes a spray tip body having a top and a lower end, a handle arranged on the top of the spray tip body, and a chamfer defined at the lower end of the spray tip body. The spray tip body further includes a retaining shoulder and a ring collar, a mounting hole having a channel axis, a pre-atomizing component, and a tip atomizing component. The pre-atomizing component further includes a feeding channel, a pre-atomization channel, and a pre-atomization regulating channel. The feeding channel, the pre-atomization channel, and the pre-atomization regulating channel are three coaxial hollow channels sequentially defined and connected along the channel axis inside the pre-atomizing component.

Abstract: A saddle seal assembly for a high-pressure airless spray nozzle having a spray tip includes a metal sealing sleeve, a cylindrical elastic seal, and a metal sleeve insert. The metal sealing sleeve may include a first saddle-shaped semi-cylinder surface closely matching with an outer surface of the spray tip to form an outer hard sealing structure. The cylindrical elastic seal may include a second saddle-shaped semi-cylinder surface closely matching with the outer surface of the spray tip to form an inner flexible sealing structure. The metal sleeve includes a hollow cylinder shape that matches the inner surface of the cylindrical elastic seal.
