  • Patent number: 9095857
    Abstract: The present invention is to provide a paint spray-gun even-pressure diverting housing structure formed by an inter housing and an outer housing, and the assembly is slotted into the paint spray-gun head cavity wherein the centers of both housings are respectively installed with holes for paint spray-gun nozzle cross-assembled into a set. The inner housing and the outer housing are installed using with two independent guiding gas channels for sending spraying paint airflow and atomization airflow, and the gaps of each guiding gas channel are cross-positioned in conduction. As the inner housing and outer housing are combined the channels of the two housing maintain the crossing relationship, thereby the spitted airflow and the atomization airflow spitted present circulating stream in the two guiding gas channels in both housings delay the time staying in the nozzle cavity, further to achieve even-exiting air effect and improve painting quality.

  • Publication number: 20150165456
    Abstract: The present invention is to provide a paint spray-gun housing structure, in particular an innovative design to improve atomization result in spraying paint, mainly a protruding installation at internal edge of the flank section on both sides of spray-gun housing for expanding diameter in the outer section of atomization airflow channel, in particular to expand diameter horizontally oval hole in order to add at least two atomizing holes at the wider and thicker position near the base of the flank section, and enable the atomizing holes aligned in horizontal direction, thereby the atomization airflow passing through the two flank sections of the spray-gun housing is directed to spit out from the atomizing hole, in particular for the paint spitted from the center of the spray-gun housing to form still wider and more even results, so that while expanding and adding the spraying area the spraying quality can be maintained.

  • Publication number: 20090026288
    Abstract: A double atomization paint spray gun, the nozzle bushing is additionally installed at the spray gun spray nozzle air emission annular groove and, furthermore, the base section has disposed a plurality of air ducts. When the nozzle bushing is placed over the spray nozzle, several air output guide channels are formed between the two components. At the same time, when the spray cover is fastened to the muzzle aspect of the spray gun body, another air output guide channel is formed between the spray cover and the nozzle bushing, the special capacity of which causes the paint to undergo double atomization. As such, during the large area atomization of paint, the special capacity enables atomization to occur more evenly and, furthermore, causes the atomized particles to become considerably more diminutive, thereby greatly raising atomized paint quality.
