  • the removable spray head also avoids the need to periodically clean the nozzle portion, as frequently required for media applicators with non-detachable nozzles.
  • the unitary construction of the nozzle portion and the media tube can also allow the same airbrush body to be used to apply different media (e.g., different media types, colors, etc.) by simply replacing the spray head when changing to a different media color or type, thereby eliminating the need to clean the media applicator.
  • the precise configuration of the head portion, the lumen, and the discharge tube as a single unit promotes consistency in the amount of media flow and the degree of media atomization between successive spray heads.
  • the discharge tubes can be precisely located at a predetermined position in the nozzle portions during assembly of the spray heads, and need not require assembly or adjustment by a user in the field.
  • the mounting portion of the airbrush body and the protuberance and recess coupling mechanism can help to achieve and maintain a precise alignment between the lumen of the nozzle portion and the passages of the airbrush body between successive spray heads.
  • the spray head embodiments described herein can also promote reduced waste and reduced cost because only the removable spray head, and not the entire airbrush body and/or media reservoir, need be replaced between uses.
  • the trigger portions 114, 214 of the disclosed embodiments are configured as openings that when covered direct a flow of gas through the respective spray heads to produce a flow of media
  • the trigger portions can have any suitable configuration.
  • the trigger portion can include a valve which can be directly actuated by a user, or indirectly actuated by a lever or linkage.
  • the spray heads 116, 216 can be used in combination with either of the airbrush bodies 102, 202, as desired.
  • FIG. 13 illustrates another embodiment of the media applicator 100 of FIG. 1 in which the spray head 116 is separable from and attachable to the media tube 122.
  • the media tube 122 can be coupled to and/or integrally formed with the airbrush body 102.
  • the spray head 116 is coupled to the mounting portion 118, the discharge tube 136 can be in fluid communication with the media tube 122, and the media applicator can be operable as described above.
  • the spray head 116 is detached from the airbrush body 102, the spray head 116 can be carried away, and the media tube 122 can remain with the airbrush body and the reservoir 104, as shown in FIG. 13 .
  • the spray head 216 of FIGS. 6-12 can also be configured in this manner, wherein the spray head 216 is detachable from the airbrush body 202 such that the spray head can be carried away while the media tube 222 remains with the airbrush body.
