DESCRIPTION

cosmetic air brush

Countryside

The present application relates to embodiments of nozzles and spray heads for airbrushes.

Background

Media applicators, such as airbrushes, are useful for applying media such as paint, powder, cosmetics, etc., evenly to a surface or substrate. However, due to narrow passages, relatively high gas flow rates, and the volatile nature of many media, media applicator nozzles are prone to clogging. Therefore, the media applicators must be cleaned or replaced periodically. Cleaning and unclogging media applicators can be time consuming and result in lost productivity. Also, typical media applicators must be cleaned before the media applicator can be used to apply a different color or type of media. Replaceable media applicators also often require the entire airbrush body to be replaced, sometimes along with the media reservoir that holds the media to be applied, resulting in wasted media and increased costs. bills. Accordingly, there is a need for improved media applicators. US 1 501 432 A relates to an airbrush which allows the use of interchangeable nozzles for different applications of the airbrush. The ejector nozzle comprises a supply pipe connection, a supply chamber and an outlet channel, which ends in a threaded connection into which the nozzle tip is screwed. The connecting end of the nozzle is threaded into the threaded connection to fit the walls of the conical cavity to the tip of the ejector nozzle. The volume of air in this airbrush increases by turning the nozzle out and decreases by turning the nozzle in; thus decreasing and increasing, respectively, the amount of suction in the ejector nozzle passage.

Detailed description

First representative realization

Figure 1 illustrates a representative embodiment of a media applicator configured as an airbrush 100 including an airbrush body 102 coupled to a media reservoir 104. In the illustrated configuration, media reservoir 104 is configured as a bottle containing media. 106 (see Figures 3 and 4) for the airbrush 100 to apply to a target substrate. The medium 106 can be a liquid medium, such as paint, a liquid cosmetic, etc., or a dry medium, such as a powder. The airbrush 100 can be configured to mix media 106 from a discharge tube 136 (FIG. 2) with compressed gas from a lumen 142 located adjacent and at an angle to the discharge tube in a manner generally associated with an "external mix" airbrush. ". Airbrush body 102 may include a handle portion 108 and a coupling portion 110 configured to engage media reservoir 104. In some examples, coupling portion 110 may include threads on an inner surface of the mounting portion configured to engage. engage the corresponding threads on the top of the media reservoir, so that the airbrush body 102 and media reservoir 104 can be secured together in threaded engagement. The handle portion 108 of the airbrush body 102 may include a gripping portion 112 by which a user can grip the airbrush body and a trigger portion 114. Activation of the trigger portion 114 by a user can cause the airbrush 100 to discharge a stream of media onto a substrate target, as described below.

Referring to Figures 1 and 2, the airbrush further comprises a removable spray head 116, which can be located in a mounting portion 118 of the airbrush body 102. The spray head 116 includes a nozzle portion 120 and a spray tube. media 122 engaged and in fluid communication with nozzle portion 120. As shown in Figure 1, when spray head 116 is located on airbrush body 102, nozzle portion 120 may be located on spray head 120. mount 118 on the exterior of the airbrush body, and media tube 122 may extend into media reservoir 104 through an opening 124 defined in the airbrush body (see, for example, Figure 5). Media tube 122 and nozzle portion 120 of spray head 116 may be formed integrally with one another so that spray head 116 is a unitary construction. As used herein, the terms "integrally formed" and "unitary construction" refer to a construction that does not include welds, fasteners, or other means for securing separately formed pieces of material to one another. Alternatively, the nozzle portion and the media tube may be separately formed and attached to each other, for example, by suitable coupling mechanisms, adhesive, press fit, etc.

Figure 2 illustrates the nozzle portion 120 in greater detail. The mouthpiece portion 120 may include a base portion 126 having first and second barb portions 128, 130 and a head portion 132. A cone-shaped support 134 may be located adjacent to the head portion 132 and may be defining an opening in which the media discharge tube 136 is received. The discharge tube 136 may be positioned so that an outlet 138 of the discharge tube is positioned adjacent an outlet 140 of the lumen 142 defined in the head portion 132. In the illustrated embodiment, outlet 138 of discharge tube 136 and outlet 140 of lumen 142 are oriented at an angle of about 90 degrees relative to each other, although other angles (eg, between about 45 degrees and about 90 degrees) are possible. degrees). Spray head 116 may also include a vent channel 144 defined in base portion 126 and extending the length of at least a portion of media tube 122.

Figures 3 and 4 are cross-sectional views of the airbrush body 102 and spray head 116. As shown in Figures 3 and 4, a main lumen 146 of media tube 122 may be in fluid communication with the media tube. discharge tube 136 located in bracket 134 such that media 106 can flow from the media reservoir, through the media tube, and into the discharge tube 136 when trigger 114 is activated.

Airbrush body 102 may also define one or more passageways in fluid communication with lumen 142. For example, in the illustrated configuration, airbrush body 102 may define a first passageway 148 located adjacent to the handle portion 108 of the body. of the airbrush. Passage 148 may be in fluid communication with an inlet port 150 (see Figure 1), and with an outlet port 152 defined by trigger portion 114. The airbrush body may further define a second passage 154 in fluid communication. with the first passage 148, and including an inlet end 156 and an outlet end 158. As shown in Figures 3 and 4, the inlet end 156 of the second passage 154 may be in fluid communication with the first. passage 148, while the outlet end 158 of the second passage may be in fluid communication with the lumen 142 of the spray head 116 when the spray head is attached to the body of the airbrush. In the illustrated embodiment, the outlet end 158 of the second passage 154 may have a smaller diameter than the middle of the second passage to increase the velocity of the compressed gas passing through the outlet end into the lumen 142.

In the illustrated configuration, the spray head 116 may be retained in the airbrush body 102 by a coupling mechanism configured as a protrusion or protrusion 172 defined on a rear surface of the head portion 132. In the illustrated configuration, the protrusion 172 may be annular and may surround the entrance port of lumen 142. When spray head 116 is located in mounting portion 118, protrusion 172 may be received in a corresponding recess 174 defined in the opposite surface of the airbrush body, as is best shown in Figures 3 and 4. In this manner, the bulge 172 and recess 174 can serve to maintain precise alignment between the lumen 142 and the second passageway 154 during use.

The operation of the airbrush can proceed as follows. Compressed gas (eg, air) may be received into the airbrush body through inlet 150 from a source of compressed gas configured as a hose 160 illustrated in Figure 1. Referring to Figure 3, when the inlet port outlet 152 of trigger portion 114 is uncovered, compressed gas may flow from inlet 150 to first passage 148, as indicated by arrows 162, and may exit the airbrush body through outlet port 152 as indicated. the arrows. 164. In this scenario, no media stream occurs. Referring to Figure 4, when the trigger portion 114 is activated, for example when a user covers the outlet port 152 with a finger 166, compressed gas may flow from the first passage 148 to the second passage 154, as indicated by arrows 168, and from the second passage to the lumen 142 of spray head 116 after accelerating through the narrow exit end 158 of the second passage.

As compressed gas exits lumen 142, it may pass over and/or around outlet 138 of discharge tube 136. This flow of gas through outlet 138 may cause a drop in pressure in the discharge tube. discharge 136 according to Bernoulli's principle, causing medium 106 to be drawn from the reservoir through lumen 146 and into the gas stream from discharge tube 136 as atomized media stream 170, as shown in Figure 4. Trigger 114 can be repeatedly turned on and off as desired to apply media to a substrate. Air may be drawn into media reservoir 104 through vent channel 144 to equalize pressure in the media reservoir as media 106 is discharged from spray head 116.

When a desired amount of media has been applied to the substrate, or if a portion of the spray head 116 becomes clogged (for example, the discharge tube 136), the spray head 116 can be removed from the airbrush body 102 and the media reservoir 104, as illustrated in Figure 5. For example, in the illustrated configuration, a user can grasp the tab portions 128, 130 of the base 126 and pull the spray head up in the direction of arrow 176 so that protrusion 172 disengages recess 174 to disengage nozzle portion 120 from airbrush body 102 while media tube 122 is withdrawn from reservoir 104 through opening 124. This allows spray head 116 to detach easily from the airbrush body without the need to disconnect the airbrush body from the media reservoir or compressed gas source 160. A clean replacement spray head can then be attached to the airbrush by inserting the tu media 122 into the reservoir and positioning the nozzle portion 120 in the mounting portion 118 so that the protrusion 172 fits into the recess 174. The application of the medium to the substrate can then be resumed.

Second Representative Realization

Figures 6-12 illustrate another embodiment of a media applicator configured as an airbrush 200 and adapted to mix a medium supplied from a discharge tube with a flow of compressed gas produced coaxially around the discharge tube in a manner generally associated with a "internal mix" airbrush. The airbrush 200 comprises an airbrush body 202 coupled to a media reservoir 204 containing a medium 206 (eg, a liquid medium or a dry or powdered medium) (see Figures 10 and 11). Airbrush body 202 may include a handle portion 208 and a coupling portion 210 configured to engage media reservoir 204, for example, by complementary threads, similar to the embodiment of Figures 1-5 above. Handle portion 208 may include a grip portion 212 and a trigger portion 214. A removable spray head 216 may be located in a mounting portion 218 of the airbrush body and oriented to project a flow medium toward a target substrate, similar to media applicator 100 described above.

Figure 7 illustrates the top of spray head 216 in greater detail. Spray head 2162 includes J a nozzle portion 220 and a media tube 222 coupled to the nozzle portion and extending to media reservoir 204 through an opening 224 defined in the airbrush body (see Figure 12). The mouthpiece portion 220 may include a base portion 226 having first and second tab portions 228, 230 similar to the embodiment described above, and a head portion 232. The head portion 232 may include a cap portion. head portion 234 (also known as a crown cap portion) with a longitudinal axis oriented perpendicular to a longitudinal axis of the media tube 222. Head portion 232 and air header portion 234 may define a lumen 236 with a tube discharge 238 located in it. Spray head 216 may also define a vent channel 244 extending from base 226 along at least a portion of the length of media tube 222. Figure 8 is a cross-sectional view taken along line 8-8 of Figure 7, and illustrates the internal structure of head portion 232 and air cap 234. Referring to Figures 7, 8 and 9, discharge tube 238 can be placed in lumen 236 and be supported by a support member 240 such that a longitudinal axis of the discharge tube 238 is coaxially aligned with a longitudinal axis of the lumen 236. As shown in Figures 8 and 9, the lumen 236 may at least partially surround the tube. discharge 238, apart from the location where the support member 240 extends from the main body of the head portion 232.

Figures 10 and 11 are cross-sectional views of the airbrush body 202 and spray head 216. The airbrush body 202 defines a first passage 242, which may be in communication with an inlet 246 and an outlet 248, similar to the embodiment of Figure 1. The airbrush body may also define a second passage 250, wherein an inlet end 252 of the second passage is in fluid communication with the first passage 242 and an outlet end 254 of the second passage is in fluid communication. fluids with the lumen 236 of the spray head 216. Activation of the trigger portion 214 (for example, by covering the outlet 248 with a finger 256) may cause compressed gas entering the first passage 242 from the inlet 246 (for example, , from source 160) is directed from the first passage to the second passage in the manner indicated by arrows 258. From the second passage 250, compressed gas can enter lumen 236 and flow around the support element. rte 240, as indicated by arrow 260 (Figure 11).

In the illustrated embodiment, spray head 216 may be retained in airbrush body 202 by a protrusion or protrusion 268 defined on a rear surface of head portion 232. In the embodiment shown, protrusion 268 may be annular and may surround the entrance hole of the lumen 236, as best shown in Figures 9, 10 and 11. Projecting portion 268 may be received in a recess 270 defined in an opposite surface of the airbrush body, similar to the embodiment of Figure 1 above. In the illustrated configuration, the bulge 268 may coaxially surround the inlet end of the lumen 236, and the recess 270 may coaxially surround the outlet end 254 of the second passage 250. In this manner, engaging the recess 270 with the bulge 268 may maintain the alignment between the second passage 250 and the lumen 236 during use.

As best shown in Figure 11, the discharge tube 238 may extend beyond an outlet 262 of the lumen 236. In the illustrated embodiment, the diameter D of the lumen 236 may decrease with decreasing distance from the lumen outlet 262 beginning at the location generally indicated at 264. In this manner, compressed gas can be accelerated toward outlet 262 of lumen 238. Upon exiting through outlet 262, the flow of compressed gas around outlet 274 of discharge tube 238 can reduce the pressure in the discharge tube according to Bernoulli's Principle. This, in turn, can cause media 206 to be drawn from reservoir 204 into media tube 222 and discharge tube 238, from where media can be introduced into the gas stream and atomized as media stream 266 and directed towards a target substrate.

When a desired amount of media has been applied to the substrate, or if a portion of the spray head 216 becomes clogged, the spray head 216 can be removed from the airbrush body 202 and media reservoir 204, similar to the embodiment of Figure 1 up. For example, as illustrated in Figure 12, a user can grasp the tab portions 228, 230 of the base 226 and pull the spray head up in the direction of arrow 272 so that the protrusion 268 disengages from the recess. 270 to disengage the nozzle portion 220 from the mounting portion 218. This allows the media tube 222 to be withdrawn from the reservoir 204 through the opening 224 so that the spray head 116 can be removed without disengaging the airbrush body from the reservoir. media or disconnect the airbrush body from the pressurized gas source.

The media applicator embodiments described herein can provide a variety of advantages over known media applicator systems. For example, the described embodiments can provide quick and easy replacement of a spray head without requiring the airbrush body to be separated from the media reservoir, or the airbrush body to be separated from the pressurized gas source. The removable spray head also avoids the need to periodically clean the nozzle portion, as is often required for media applicators with non-removable nozzles.

The unitary construction of the nozzle portion and 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 it is installed. changes to a different media color or type, thus eliminating the need to clean the media applicator. In addition, the precise configuration of the head portion, lumen, and discharge tube as a single unit promotes consistency in the amount of media flow and degree of media atomization between successive spray heads. For example, the discharge tubes can be precisely located in a predetermined position on the nozzle parts during the assembly of the spray heads, and do not require a user to assemble or adjust them in the field. In addition, the airbrush body mounting portion and the boss and recess coupling mechanism can help achieve and maintain precise alignment between the nozzle portion lumen and the airbrush body passages between successive spray heads. . The spray head embodiments described herein can also promote reduced waste and reduced costs because only the removable spray head, and not the entire airbrush body and/or media reservoir, needs to be replaced between uses.

Although the trigger portions 114, 214 of the described embodiments are configured as openings which, when covered, direct a flow of gas through the respective spray heads to produce a flow of media, it should be understood that the trigger portions may have any suitable settings. For example, in alternative embodiments, the trigger portion may include a valve that can be actuated directly by a user, or indirectly by a lever or link. It should also be understood that the spray heads 116, 216 can be used in combination with any of the airbrush bodies 102, 202, as desired.

Figure 13 illustrates another embodiment of the media applicator 100 of Figure 1 in which the spray head 116 may be detached and attached to the media tube 122. For example, the media tube 122 may be mated and/or integrally formed with the media tube 122. airbrush body 102. When spray head 116 is attached to mounting portion 118, discharge tube 136 may be in fluid communication with media tube 122, and the media applicator may function as described above. When the spray head 116 is separated from the airbrush body 102, the spray head 116 can be removed and the media tube 122 can remain with the airbrush body and reservoir 104, as shown in Figure 13. The spray head 216 of Figures 6-12 can also be configured this way, where the spray head 216 can be detached from the airbrush body 202 so that the spray head can be worn while the media tube 222 remains with the airbrush body.
