Definitions

  • the present invention is a paint spray-gun even-pressure diverting housing structure, mainly through the gap crossing position guiding style design of its diverting housing so that its airflow is able to circulate through and extend its time in staying in the cavity of the spray-gun head.
  • the spraying paint airflow and atomization airflow are spit out evenly from the spitting hole of air outlet in the center of the spray-gun housing and both sides of the flank section.
  • a connector is installed for connecting to the air compression device, and another knob is installed to control the inlet air volume in order to adjust the degree of paint atomization accommodating with the pressing handle installed on the upper cavity section of the handle section for the control of the trigger cross installed in the cavity section of the main body in order to control the opening of the nozzle on the front.

Therefore, the guiding gas channels are installed in penetrating style. In this way, as the spraying paint airflow and the atomization airflow are spit out from their respective holes, they are blown out from the air outlet and spitting hole directly through the guiding gas channel of diverting housing. Due to the missing of even pressure design and adding the strengths of air pressures guided from the spray-gun might not be the same, leading the outlet air might be unstable. Hence, the spraying paint volume and the stability of atomization airflow are seriously affected, resulting in the quality of praying paint hard to maintain and indeed requires to be resolved and improved.
