Definitions
- the invention is directed to a device for spraying pigmented liquids by means of an air stream comprising a base body, a spray nozzle arranged at the front of the main body, a compressed air inlet and a subsequent compressed air channel, an inlet for a pigmented liquid, one supplied through the compressed air channel adjustable compressed air flow past a pigmented liquid inlet and loaded with liquid droplets and these liquid droplets are discharged through the spray nozzle as long as the compressed air flow is maintained.
- Such devices are commonly referred to as airbrushes or "airbrush guns.”
- the entrainment of the liquid droplets is due to a negative pressure created by a Venturi effect. "In principle, very different media can be applied with such a device spoken by color.
- a generic device is known from US 5,454,517.
- a disadvantage of such devices is that when changing to a different color or after a long break in use, the nozzle must be cleaned, which is time consuming and laborious and also involves the risk that damaging the delicate, arranged in the nozzle needle which can lead to drastic dysfunctions or inability to function.
- the invention is based on the object, such a device in such a way that they can be produced very inexpensively and advantageous in handling, in particular a cleaning of the nozzle can be avoided with the associated problems.
- the nozzle and the needle are seated in a paint-guiding nozzle part, wherein the ink-carrying nozzle part has the inlet for the pigmented liquid, and wherein the ink-carrying nozzle part as a whole are removable or exchangeable.
- This embodiment has the very significant advantage that all acted upon by color parts can be removed or replaced together, so that a color change is completely easy and no manual cleaning required. When placing a new spray head is given no bias by another color and therefore ensures that the new color can be sprayed completely undisturbed.
- an air duct in the form of a flexible hose is provided, the diameter of which is advantageously variable, in order to adjust the air flow rate in this way.
- the actuating lever is associated with an adjustable stop for the actuating lever to achieve a constant uniform spray pattern.
- This adjustable stop is preferably formed by a threaded rod, which is axially displaceable by means of an externally accessible knurled nut.
- a nozzle hood surrounding the color channel is materially connected to the nozzle and can be fixed by a locking screw.
- An inventive device has an elongated, pin-like in the hand-durable base body 1, at the front end of a color-guiding nozzle part 2 is arranged.
- the ink-carrying nozzle part 2 comprises a conical nozzle hood 3 with a passage and guide bore 4 for a nozzle 5, a safety hood 6 engaging over the nozzle hood 3 and an annular body 7.
- the annular body 7 has an annular circumferential groove 8, in which a guide collar 9 of the base body 1 engages, so that the annular body is mounted pivotably through 360 °.
- a nozzle carrier 10 is further arranged, from which a nozzle tube 1 1 extends away, at the front end of the nozzle 5 is formed.
- a needle 12 Inside the nozzle tube 11 sits a needle 12, which is acted upon by a coil spring 13.
- the coil spring 13 and the needle 12 are arranged in a longitudinal bore 14 of the nozzle carrier 10, wherein in this longitudinal bore 14 a, as described below, longitudinally displaceable actuating tappet 15 acts.
- the nozzle carrier 10 has a substantially round outer shape and is positively inserted into the annular body 7, wherein a lateral projection 16 of the nozzle carrier 10 in a - not visible in the drawing - slot of the annular body 7 engages and is fixed relative to the annular body 7 rotatably , which in turn but is rotatable relative to the base body 1.
- a color inlet 17 is formed in the form of a recess, wherein in the paint inlet 17, either a connecting hose can be used to a paint reservoir or the insertion of a small, directly attachable paint reservoir.
- the annular body 7 has an external thread 18, onto which the internal thread 19 of the securing hood 6 can be screwed. In this way, via the securing hood 6, the nozzle hood 3 can be fastened to the annular body 7, wherein at the same time the nozzle carrier 10, which sits in the frontal recess of the base body 1, is fixed axially.
- the ink-carrying nozzle part 2 is rotatable in total relative to the base body 1 and the nozzle carrier 10 with the ink inlet 17, the nozzle 5, the nozzle needle 12 and the coil spring 13 are interchangeable, so that no ink-carrying part remains and can be easily re-worked with a new color when inserting a new nozzle holder 10.
- the rear end of the nozzle needle 12 is connected to the coil spring 13, whereas the front end of the coil spring is supported on the narrowing nozzle 5, so that upon movement of the actuating plunger 15 forward, the coil spring 13 is compressed and upon a backward movement of the actuating plunger 15 the Coil spring 13, the nozzle needle 12 with withdraws.
- the actuating plunger 15 is connected via its inner end 20 with a pivotable about a pivot axis, actuatable in the direction of arrow P ren operating lever H whose displacement against the force of a return spring 22 in the direction of arrow P causes the actuating plunger 15 after is moved to the right or rear, so that the coil spring 13, the needle 12 can shift to the right in the drawing, whereby with increasing movement to the right or rear, the passage opening of the nozzle 5 is increasingly increased and, accordingly, more color can be delivered.
- an air inlet 23 is provided at the rear end of the main body 1.
- an air channel 24 connects from the inside to a hose-like, flexible material. Slanted to the air channel 24 extends a guide 25 for a provided with a knurled surface thumb wheel 26 which engages in the compressed air channel 24 and this further opens by displacement to the front and by shifting to Rear closes, so that the compressed air passage can be adjusted in this way.
- the compressed air channel 24 opens into the conically tapering nozzle hood 3, wherein the air flow is accelerated and flows past the nozzle 5 and entrains the ink from a color channel 27 adjoining the ink inlet 17 due to the negative pressure built up by the Venturi effect. so that a color-air mixture flows through the nozzle 5.
- the compressed air structure can be done for example by means of a compressor.
- the working pressure is a maximum of 3 bar.
- the air channel 24 passes by the lever H and is squeezed off at 28 when the lever H is in the forward closed state.
- moving the lever H direction of the arrow P is then, as already described, by displacing the needle to the rear of the nozzle 5 released and at the same time the compressed air channel 24 is opened.
- the path of the release lever 17 can be limited or adjusted by a knurled nut 29 in order to maintain a constant spray line strength over a longer period of time.
- the knurled nut 29 is seated on a threaded rod 30, which is displaced axially by a rotary movement of the knurled nut 29 and thus forms an adjustable stop for the release lever 17.
