Die Erfindung richtet sich auf eine Vorrichtung zum Aufsprühen von pigmentierten Flüssigkeiten mittels eines Luftstroms umfassend einen Grundkörper, eine an der Vorderseite des Grundkörpers angeordnete Sprühdüse mit einer darin mittig angeordneten Nadel, einen Drucklufteinlass und einen anschließenden Druckluftkanal, eine Austrittsöfnung für eine pigmentierte Flüssigkeit, wobei ein durch den Druckluftkanal zugeführter regelbarer Druckluftstrom an der Austrittsöffnung für die pigmentierte Flüssigkeit vorbeigeführt und mit Flüssigkeitströpfchen beladen wird und diese Flüssigkeitströpfchen durch die Sprühdüse abgegeben werden, solange der Druckluftstrom sufrechterbalten wird, wobei die Düse und die Nadel in einem Düsenkopf angeordnet sind und der Düsenkopf als Ganzes entfernbar bzw, austauschbar ist.The invention is directed to a device for spraying pigmented liquids by means of an air stream comprising a base body, a arranged at the front of the body spray nozzle with a centrally disposed therein needle, a compressed air inlet and a subsequent compressed air channel, a discharge opening for a pigmented liquid, wherein passed through the compressed air duct controllable compressed air flow at the outlet opening for the pigmented liquid and loaded with liquid droplets and these liquid droplets are discharged through the spray nozzle as long as the compressed air flow is sufrechterbalten, the nozzle and the needle are arranged in a nozzle head and the nozzle head as a whole removable or exchangeable.

Eine solche Vorrichtung wird in DE 10 2005 038 162 A1 beschrieben, gemäß dem Oberbergriff von Anspruch 1.Such a device is in DE 10 2005 038 162 A1 described, according to the Oberbergriff of claim 1.

Bei der vorbekannten Vorrichtung ist vorgesehen, dass die pigmentierte Flüssigkeit aus einem externen Vorratsbehälter über eine Einlassöffnung zugeführt wird. Die von extern zugeführte Flüssigkeit wird auf dem Weg von der Einlassöffnung zur Sprühdüse durch einen in dem Düsenkopf vorgesehenen Raum, der auch als Aufnahmeraum bezeichnet werden kann, hindurch geleitet. Ein Betrieb ohne externe Flüssigkeitszufuhr ist nicht vorgesehen.In the previously known device it is provided that the pigmented liquid is supplied from an external storage container via an inlet opening. The externally supplied liquid is passed on the way from the inlet opening to the spray nozzle through a space provided in the nozzle head, which may also be referred to as a receiving space. Operation without external fluid supply is not provided.

Eine ähnliche Vorrichtung zum Aufsprühen von pigmentierten Flüssigkeiten wird in der GB 102 910 A beschrieben. Auch bei dieser Vorrichtung kann der Düsenkopf als Ganzes zu Reinigungszwecken entfernt werden. Es ist ebenfalls eine Einlassöffnung zur externen Zuführung der pigmentierten Flüssigkeit vorgesehen, wobei die pigmentierte Flüssigkeit von der Einlassöffnung zur Sprühdüse wiederum durch einen in dem Düsenkopf vorgesehenen Raum hindurch geleitet wird. Auch diese Sprühvorrichtung ist nicht für einen Betrieb ohne externe Flüssigkeitszufuhr ausgelegt.A similar device for spraying pigmented liquids is described in US Pat GB 102 910 A described. Also in this device, the nozzle head as a whole can be removed for cleaning purposes. It is also an inlet port for external delivery of the pigmented Liquid is provided, wherein the pigmented liquid from the inlet opening to the spray nozzle is in turn passed through a space provided in the nozzle head space. Also, this spray device is not designed for operation without external fluid supply.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung der gattungsgemäßen Art so auszugestalten, dass die Handhabung noch mehr vereinfacht wirdOn this basis, the invention has the object, a device of the generic type in such a way that the handling is even more simplified

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass in dem Düsenkopf ein Vorratsbehälter für die zu versprühende pigmentierte Flüssigkeit angeordnet ist. Innerhalb des Vorratsbehälters ist ein Aufnahmeraum zur Aufnahme der aufzusprühenden pigmentierten Flüssigkeit gebildet, so dass der Düsenkopf mit einem integrierten Flüssigkeitstank ausgestattet ist und die Vorrichtung unabhängig von einer externen Flüssigkeitszuführung betrieben werden kann. Der Vorratsbehälter kann dann mit dem Düsenträger bereits gefüllt erworben werden oder individuell befüllt bzw. nachgefüllt werden.This object is achieved in that a reservoir for the pigmented liquid to be sprayed is arranged in the nozzle head. Within the reservoir, a receiving space for receiving the aufzuspühenden pigmented liquid is formed so that the nozzle head is equipped with an integrated liquid tank and the device can be operated independently of an external liquid supply. The reservoir can then be purchased already filled with the nozzle carrier or individually filled or refilled.

Hierzu ist eine mit dem Vorratsbehälter verbundene Befüllungsöffnung vorgesehen sein, die von einer geschlitzten Membran abgedeckt ist, die vorzugsweise aus Silikon bestehen kann.For this purpose, a filling opening connected to the reservoir is provided, which is covered by a slotted membrane, which may preferably consist of silicone.

Zur Erzielung eines kompakten, symmetrischen Aufbaus kann der Vorratsbehälter um die Nadel herum angeordnet sein.To achieve a compact, symmetrical construction, the reservoir can be arranged around the needle.

Gemäß einer weiteren bevorzugten Ausgestaltung weist der Vorratsbehälter eine hohlzylindrische Grundform mit einem konisch zulaufenden und die Austrittsöffnung bildenden vorderen Endbereich und einem hinteren Endbereich auf. Dabei ist im hinteren Endbereich ein Dichtungselement in den Vorratsbehälter eingesetzt ist. Die genamten beiden Endbereiche sind in Bezug auf die axiale Richtung, also die durch die Längsmittenachse der Nadel definierte Richtung, vorne bzw. hinten angeordnet. So ist innerhalb des Vorratsbehälters ein vorne und hinten abgedichteter Hohlraum zur Aufnahme der pigmentierten Flüssigkeit gebildet. Die hintere Abdichtung erfolgt über das Dichtungselement, das insbesondere aus Teflon besteht. Die vordere Abdichtung erfolgt insbesondere dadurch, dass die Nadel in ihrer Ruheposition, d.h. im nicht betätigten Zustand, die Austrittsöffnung verschließt. Sie kann dazu in einen konisch zulaufenden Sitz der Austrittsöffnung gepresst sein und/oder sich auch nur eng anliegend in diesem Sitz befinden.According to a further preferred embodiment, the reservoir has a hollow cylindrical basic shape with a tapered and the outlet opening forming the front end portion and a rear End area on. In this case, a sealing element is inserted into the reservoir in the rear end region. The genamten two end portions are arranged with respect to the axial direction, ie the direction defined by the longitudinal center axis of the needle direction, front or rear. Thus, within the reservoir a front and rear sealed cavity for receiving the pigmented liquid is formed. The rear seal via the sealing element, which consists in particular of Teflon. The front seal is made in particular by the fact that the needle in its rest position, ie in the non-actuated state, closes the outlet opening. It can be pressed into a tapered seat of the outlet opening and / or even close fitting in this seat.

Gemäß einer weiteren bevorzugten Ausgestaltung liegt das Dichtungselement abdichtend eng an einer Innenwand des Vorratsbehälters an. Das Dichtungselement weist außerdern eine Durchgangsöffnung auf, durch die die Nadel axial bewegbar hindurch geführt ist, wobei ein Kontakt zwischen dem Dichtungselement und der Nadel innerhalb der Durchgangsöffnung abdichtend eng ist. Das Dichtungselement ist insbesondere mittels einer Presspassung in den Vorratsbehälter eingefügt. Auch zwischen der Nadel und dem Dichtungselement liegt vorzugsweise eine Art Presspassung vor, deren Kontaktkraft aber vorteilhafterweise geringer ist als zwischen dem Dichtungselement und der Innenwand des Vorratsbehälters, da sich die Nadel innerhalb der Durchgangsöffnung hin und her bewegen können sollte. So sind die beiden Kontaktflächen zwischen dem Dichtungselement und dem Vorratsbehälter zum einen und zwischen dem Dichtungselement und der Nadel zum anderen jeweils dicht, d.h. insbesondere dicht gegenüber einem Austritt der pigmentierten Flüssigkeit, ausgeführt.According to a further preferred embodiment, the sealing element sealingly abuts against an inner wall of the storage container. The sealing element also has a through opening through which the needle is guided axially movable, wherein a contact between the sealing element and the needle within the passage opening is tight sealing. The sealing element is inserted in particular by means of a press fit in the reservoir. Also between the needle and the sealing member is preferably a kind of interference fit, but the contact force is advantageously less than between the sealing member and the inner wall of the reservoir, as the needle should be able to move back and forth within the passage opening. Thus, the two contact surfaces between the sealing element and the reservoir on the one hand and between the sealing element and the needle to the other in each case dense, ie in particular sealed against an exit of the pigmented liquid executed.

Gemäß einer weiteren bevorzugten Ausgestaltung ist eine Kontaktkraft zwischen dem Dichtungselement und der durch das Dichtungselement hindurch geführten Nadel so ausgelegt, dass eine Relativposition zwischen dem Dichtungselement und der Nadel ohne äußere Krafteinwirkung erhalten bleibt. Unter einer äußeren Krafteinwirkung ist hierbei insbesondere die Krafteinwirkung durch den Betätigungsstößel der Aufsprühvorrichtung zu verstehen. Dadurch ist vor allem gewährleistet, dass die Nadel nicht von sich aus und nicht ohne äußeres Zutun ihre Ruheposition, bei der sie sich eng anliegend und insbesondere abdichtend eng in dem Sitz der Austrittsöffnung befindet, verlässt. Insbesondere ist ein Durchgangsdurchmesser der Durchgangsöffnung des Dichtungselement um etwa 1 % bis etwa 5 %, vorzugsweise um etwa 2 %, kleiner als ein Nadeldurchmesser der Nadel in dem Bereich, der sich im montierten Zustand innerhalb der Durchgangsöffnung befindet. Gemäß einer alternativen Ausgestaltung ist es aber ebenso möglich, dass eine zusätzliche Feder vorgesehen ist, die die Nadel in den Sitz der Austrittsöffnung presst und so verhindert, dass die Austrittsöffnung versehentlich frei gegeben wird und es zu einem dann unerwünschten Auslaufen der im Vorratsbehälter befindlichen pigmentierten Flüssigkeit kommt.According to a further preferred embodiment, a contact force between the sealing element and the guided through the sealing element needle is designed so that a relative position between the sealing element and the needle is maintained without external force. Under an external force in this case is to be understood in particular the force by the actuating plunger of the Aufsprühvorrichtung. This ensures, above all, that the needle does not leave by itself and not without external intervention its rest position, in which it is tight fitting and in particular sealingly tight in the seat of the outlet opening leaves. In particular, a passage diameter of the passage opening of the sealing member is about 1% to about 5%, preferably about 2%, smaller than a needle diameter of the needle in the area which is in the mounted state within the passage opening. According to an alternative embodiment, it is also possible that an additional spring is provided which presses the needle in the seat of the outlet opening and thus prevents the outlet opening is accidentally released and it is then undesirable Leakage of the pigmented liquid in the reservoir comes.

Gemäß einer weiteren bevorzugten Ausgestaltung ist die Nadel an ihrem hinteren Ende mechanisch fest, aber lösbar mit einem Betätigungsstößel verbunden. Dadurch werden zugleich eine Austauschbarkeit des Düsenkopfs sowie eine trotzdem einfache und sichere Betätigung der Aufsprühvorrichtung ermöglicht.According to a further preferred embodiment, the needle is mechanically fixed at its rear end, but releasably connected to an actuating tappet. As a result, at the same time an interchangeability of the nozzle head and a still simple and safe operation of the Aufsprühvorrichtung possible.

Gemäß einer weiteren bevorzugten Ausgestaltung ist die Verbindung zwischen dem hinteren Ende der Nadel und dem Betätigungsstößel mittels eines Formschlusses realisiert. Beispielsweise ist eine Art lösbarer Bajonettverschluss zwischen dem hinteren Ende der Nadel und dem Betätigungsstößel vorgesehen.According to a further preferred embodiment, the connection between the rear end of the needle and the actuating plunger is realized by means of a positive connection. For example, a kind of releasable bayonet lock is provided between the rear end of the needle and the actuating tappet.

Nachfolgend wird die Erfindung anhand eines bevorzugten Ausführungsbeispiels in Verbindung mit der Zeichnung näher erläutert. Dabei zeigen

a section through the nozzle carrier according to the inventive solution.

Eine gattungsgemäße Vorrichtung weist einen länglichen, stiftartig in der Hand haltbaren Grundkörper 1 auf, an dessen vorderen Ende ein farbführendes Düsenteil 2 angeordnet ist.A generic 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.

Das farbführende Düsenteil 2 umfasst eine konische Düsenhauben 3 mit einer Durchlass- und Führungsbohrung 4 für eine Düse 5, eine die Düsenhaube 3 übergreifende Sicherungshaube 6 und einen Ringkörper 7.The ink-carrying nozzle part 2 comprises a conical nozzle hoods 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.

Der Ringkörper 7 weist eine ringförmig umlaufende Nut 8 auf, in die ein Führungskragen 9 des Grundkörpers 1 eingreift, sodass der Ringkörper 7 um 360° schwenkbar gelagert ist.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 7 is mounted pivotably through 360 °.

In dem farbführenden Düsenteil 2 ist weiterhin ein einen Düsenkopf bildender Düsenträger 10 angeordnet, von dem sich ein Düsenrohr 11 wegerstreckt, an dessen vorderen Ende die Düse 5 ausgebildet ist. Im Inneren des Düsenrohrs 11 sitzt eine Nadel 12, welche von einer Schraubenfeder 13 beaufschlagt ist. Die Schraubenfeder 13 und die Nadel 12 sind in einer Längsbohrung 14 des Düsenträgers 10 angeordnet, wobei in diese Längsbohrung 14 ein, wie nachfolgend beschrieben, längsverschiebbarer Betätigungsstößel 15 einwirkt.In the ink-guiding nozzle part 2, a nozzle carrier 10 which forms a nozzle head is furthermore arranged, from which a nozzle tube 11 extends, at the front end of which the nozzle 5 is formed. 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.

Der Düsenträger 10 besitzt eine im Wesentlichen runde Außenform und ist formschlüssig in den Ringkörper 7 einsetzbar, wobei ein seitlicher Ansatz 16 des Düsenträgers 10 in einen - in der Zeichnung nicht erkennbaren - Schlitz des Ringkörpers 7 eingreift und dementsprechend relativ zu dem Ringkörper 7 drehfest festgelegt ist, welcher seinerseits aber relativ zum Grundkörper 1 verdrehbar ist.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.

In dem Ansatz 16 ist in Form einer Ausnehmung ein Farbeinlass 17 ausgebildet, wobei in den Farbeinlass 17 entweder ein Verbindungsschlauch zu einem Farbvorratsbehälter eingesetzt werden kann oder der Steckansatz eines kleinen, unmittelbar aufsetzbaren Farbvorratsbehälters.In the projection 16, 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.

Der Ringkörper 7 weist ein Außengewinde 18 auf, auf welches das Innengewinde 19 der Sicherungshaube 6 aufschraubbar ist. Auf diese Weise kann über die Sicherungshaube 6 die Düsenhaube 3 am Ringkörper 7 befestigt werden, wobei gleichzeitig der Düsenträger 10, der in der stirnseitigen Ausnehmung des Grundkörpers 1 sitzt, axial festgelegt wird.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, the nozzle hood 3 can be attached to the ring body 7 via the securing hood 6, wherein at the same time the nozzle carrier 10, which sits in the frontal recess of the base body 1, is axially fixed.

Aus dem Vorstehenden wird deutlich, dass das farbführende Düsenteil 2 insgesamt relativ zum Grundkörper 1 verdrehbar ist und der Düsenträger 10 mit dem Farbeinlass 17, der Düse 5, der Düsennadel 12 und der Schraubenfeder 13 austauschbar sind, sodass kein farbführendes Teil zurückbleibt und beim Einsetzen eines neuen Düsenträgers 10 völlig problemlos mit einer neuen Farbe weitergearbeitet werden kann.From the above it is clear that the ink-carrying nozzle part 2 is rotatable relative to the main body 1 as a whole 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 when inserting a new nozzle carrier 10 can be easily continued with a new color.

Das hintere Ende der Düsennadel 12 ist mit der Schraubenfeder 13 verbunden, wohingegen das vordere Ende der Schraubenfeder 13 sich an der sich verengenden Düse 5 abstützt, sodass bei einer Bewegung des Betätigungsstößels 15 nach vorne die Schraubenfeder 13 komprimiert wird und bei einer Rückwärtsbewegung des Betätigungsstößels 15 die Schraubenfeder 13 die Düsennadel 12 mit zurücknimmt.The rear end of the nozzle needle 12 is connected to the coil spring 13, whereas the front end of the coil spring 13 is supported on the narrowing nozzle 5, so that upon movement of the actuating plunger 15 forward the coil spring 13 is compressed and during a backward movement of the actuating plunger 15th the coil spring 13, the nozzle needle 12 with withdraws.

Der Betätigungsstößel 15 ist über sein inneres Ende 20 mit einem um eine Schwenkachse 21 schwenkbar gelagerten, in Richtung des Pfeils P betätigbaren Betätigungshebel H verbunden, dessen Verlagerung gegen die Kraft einer Rückstellfeder 22 in Richtung des Pfeils P dazu führt, dass der Betätigungsstößel 15 nach rechts bzw. hinten bewegt wird, sodass die Schraubenfeder 13 die Nadel 12 in der Zeichnung nach rechts verlagern kann, wodurch mit zunehmender Bewegung nach rechts bzw. hinten die Durchlassöffnung der Düse 5 zunehmend vergrößert wird und dementsprechend mehr Farbe abgegeben werden kann.The actuating plunger 15 is connected via its inner end 20 with a pivotable about a pivot axis 21, operable in the direction of arrow P operating lever H, the displacement against the force of a return spring 22 in the direction of arrow P causes the actuating plunger 15 to the right or moved rearward, 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.

Am rückseitigen Ende des Grundkörpers 1 ist ein Lufteinlass 23 vorgesehen. An den Lufteinlass 23 schließt sich nach innen ein Luftkanal 24 aus einem schlauchartigen, flexiblen Material an. Schräg zu dem Luftkanal 24 verläuft eine Führung 25 für ein mit einer gerändelten Oberfläche versehenes Stellrad 26, welches in den Druckluftkanal 24 eingreift und diesen durch Verlagerung nach vorne weiter öffnet und durch Verlagerung nach hinten schließt, sodass auf diese Weise der Druckluftdurchlass eingestellt werden kann.At the rear end of the main body 1, an air inlet 23 is provided. At the air inlet 23, an air channel 24 connects from the inside to a hose-like, flexible material. Slanted to the air duct 24 extends a guide 25 for a provided with a knurled surface thumb wheel 26 which engages the compressed air channel 24 and further opens by displacement to the front and closes by displacement to the rear, so that the compressed air passage can be adjusted in this way.

Der Druckluftkanal 24 mündet in die sich konisch verjüngendes Düsenhaube 3, wobei der Luftstrom beschleunigt wird und an der Düse 5 vorbei strömt und auf Grund des durch den Venturi-Effekt aufgebauten Unterdrucks die Farbe aus einem sich an den Farbeinlass 17 anschließenden Farbkanal 27 mitnimmt, sodass durch die Düse 5 ein Farb-Luft-Gemisch ausströmt.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 due to the negative pressure built up by the Venturi effect entrains the ink from a color channel 27 adjoining the ink inlet 17, so that through the nozzle 5, a color-air mixture flows out.

Der Druckluftaufbau kann beispielsweise mittels eines Kompressors erfolgen. Der Arbeitsdruck beträgt maximal 3 bar.The compressed air structure can be done for example by means of a compressor. The working pressure is a maximum of 3 bar.

Der Luftkanal 24 führt an dem Betätigungshebel H vorbei und wird bei 28, wenn sich der Betätigungshebel H im vorderen Schließzustand befindet, abgequetscht. Beim Verlagern des Betätigungshebels H Richtung des Pfeils P wird dann, wie bereits beschrieben, durch Verlagerung der Nadel nach hinten die Düse 5 freigegeben und gleichzeitig der Druckluftkanal 24 geöffnet.The air passage 24 passes by the operating lever H and is squeezed at 28 when the operating lever H is in the front closing state. When displacing the operating 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.

Der Weg des Betätigungshebels H kann durch eine Rändelmutter 29 begrenzt bzw. eingestellt werden, um über einen längeren Zeitraum eine konstante Sprühstrichstärke aufrecht erhalten zu können. Die Rändelmutter 29 sitzt auf einer Gewindestange 30, die durch eine Drehbewegung der Rändelmutter 29 axial verlagert wird und so einen verstellbaren Anschlag für den Betätigungshebel H bildet.The path of the actuating lever H can be limited or adjusted by a knurled nut 29 to a constant over a longer period Maintain spray bar strength upright. The knurled nut 29 is seated on a threaded rod 30, which is displaced axially by a rotational movement of the knurled nut 29 and thus forms an adjustable stop for the actuating lever H.

Bei der vorstehend beschriebenen gattungsgemäßen Vorrichtung ist vorgesehen, dass die pigmentierte Flüssigkeit über einen Farbeinlass 17 von außen zugeführt wird.In the generic device described above, it is provided that the pigmented liquid is supplied via a paint inlet 17 from the outside.

Bei dem in Fig. 2 dargestellten Ausführungsbeispiel einer erfindungsgemäßen Aufsprühvorrichtung ist demgegenüber ein austauschbarer Düsenkopf 10a vorgesehen, bei dem eine Nadel 12a und eine Schraubenfeder 13a direkt innerhalb eines im Wesentlichen hohlzylindrischen Vorratsbehälters 31 für die aufzusprühende pigmentierte Flüssigkeit angeordnet sind. Der Vorratsbehälter 31 läuft an einem vorderen axialen Ende konisch zu und weist dort eine Austrittsöffnung 32 auf, deren Innenwand einen ebenfalls nach vorne konisch zulaufenden Sitz 32a bildet. Die Nadel 12a verjüngt sich an ihrem vorderen Ende und läuft in einer Nadelspitze 12b aus, mittels der sie die Austrittsöffnung 32 durchsetzt. Die Nadelspitze 12b befindet sich in der in Fig. 2 gezeigten Ruheposition der Nadel 12a eng anliegend und gegenüber einem Flüssigkeitsaustritt abdichtend in dem Sitz 32a. Die Innenwand des Sitzes 32a und die Außenkontur der Nadelspitze 12b sind aneinander angepasst. Sie haben insbesondere jeweils die gleiche Konizität, d.h. den gleichen Neigungswinkel bezüglich der Mittenlängsachse 36 der Nadel 12a bzw. der Aufsprühvorrichtung insgesamt.At the in Fig. 2 In contrast, a replaceable nozzle head 10a is provided, in which a needle 12a and a coil spring 13a are arranged directly within a substantially hollow cylindrical reservoir 31 for the pigmented liquid to be sprayed. The reservoir 31 runs conically at a front axial end and has there an outlet opening 32, the inner wall of which also forms a forwardly tapered seat 32a. The needle 12a tapers at its front end and terminates in a needle point 12b, by means of which it passes through the outlet opening 32. The needle tip 12b is located in the in Fig. 2 shown rest position of the needle 12 a tightly against a liquid leakage and sealing in the seat 32 a. The inner wall of the seat 32a and the outer contour of the needle tip 12b are fitted together. In particular, they each have the same conicity, ie the same angle of inclination with respect to the central longitudinal axis 36 of the needle 12a or the spraying device as a whole.

Im Bereich der Austrittsöffnung 32 endet an der Außenseite des vorne konisch zulaufenden Vorratsbehälters 31 ein Düsenkopfluftkanal 24a, der mit dem in Fig. 1 gezeigten Druckluftkanal 24 in Verbindung steht. Der Düsenkopfluftkanal 24a verläuft zwischen dem Vorratsbehälter 31 und einer äußeren Düsenkappe 37 des austauschbaren Düsenkopfs 10a.In the region of the outlet opening 32 ends on the outside of the front conically tapered reservoir 31, a nozzle head air passage 24 a, with the in Fig. 1 shown compressed air channel 24 is in communication. The nozzle head air duct 24a extends between the reservoir 31 and an outer nozzle cap 37 of the replaceable nozzle head 10a.

An einem hinteren oder rückwärtigen axialen Ende des Vorratsbehälters 31 ist ein Dichtungselement in Form einer Teflondichtung 33 mittels einer gegenüber einem Flüssigkeitsaustritt abdichtenden Presspassung in den Vorratsbehälter 31 eingesetzt. Die Teflondichtung 33 hat eine zentrale Durchgangsbohrung 33a, durch die die Nadel 12a hindurch geführt ist. Die Führung der Nadel 12a innerhalb der Durchgangsbohrung 33a ist so ausgestaltet, dass zum einen eine axiale Hin- und Herbewegung der Nadel 12a möglich ist, aber zum anderen auch an dieser Stelle eine Abdichtung gegenüber einem Flüssigkeitsaustritt gewährleistet ist.At a rearward or rearward axial end of the storage container 31, a sealing element in the form of a Teflon seal 33 is inserted into the storage container 31 by means of a press fit sealing against a liquid outlet. The Teflon seal 33 has a central through-hole 33a through which the needle 12a is passed. The guidance of the needle 12a within the through hole 33a is designed so that on the one hand an axial reciprocating movement of the needle 12a is possible, but on the other hand also at this point a seal against liquid leakage is ensured.

Innerhalb des Vorratsbehälters 31 ist also ein Aufnahmeraum 31 a zur Aufnahme der aufzusprühenden pigmentierten Flüssigkeit gebildet. Dieser Aufnahmeraum 31a ist seitlich durch die Wand des Vorratsbehälters 31, vorne durch die in der Ruhestellung dicht in dem Sitz 32a der Austrittsöffnung 32 sitzende Nadelspitze 12b und hinten durch die Teflondichtung 33 begrenzt.Within the reservoir 31 so a receiving space 31 a for receiving the aufzusprühenden pigmented liquid is formed. This receiving space 31a is bounded laterally by the wall of the storage container 31, in front by the needle tip 12b seated tightly in the rest position in the seat 32a of the discharge opening 32 and rear by the Teflon seal 33.

In der hohlzylindrischen Wand des Vorratsbehälters 31 befindet sich eine Nachfüllöfnung 34, welche durch eine geschlitzte Silikonmembran 35 abgeschlossen ist. Die Silikonmembran 35, die bei dem gezeigten Ausführungsbeispiel in eine in der Düsenkappe 37 vorgesehenen weiteren und mit der Nachfiillöffnung 34 fluchtenden Öffnung 34a eingesetzt ist, hat einen Schlitz 35a, der eine Druckausgleichsfunktion erfiillt. Kommt es bei Betätigung der Aufsprühvorrichtung zu einer Entnahme von pigmentierter Flüssigkeit aus dem Aufnahmeraum 31a des Vorratsbehälters 31, kann durch den Schlitz 35a Luft in den Aufnahmeraum 31a nachströmen, so dass ein Druckausgleich stattfindet. Der sich andernfalls in dem Aufnahmeraum 31a einstellende Unterdruck könnte ansonsten die Funktionsfähigkeit der Aufsprühvorrichtung beeinträchtigen. Andererseits ist die geschlitzte Silikonmembran 35 so ausgebildet, dass die pigmentierte Flüssigkeit nicht durch den Schlitz 35a nach außen austreten kann. Die Silikonmembran 35 hat also eine Doppelfunktion. Zum einen sorgt sie für den Druckausgleich, zum anderen dichtet sie gegenüber einem Flüssigkeitsaustritt ab.In the hollow cylindrical wall of the reservoir 31 is a Nachfüllöfnung 34, which is completed by a slotted silicone membrane 35. The silicone membrane 35, which is inserted in the embodiment shown in a further provided in the nozzle cap 37 and the Nachfiillöffnung 34 opening 34a, has a slot 35a, which fulfills a pressure compensation function. If, on actuation of the spraying device, a removal of pigmented liquid from the receiving space 31a of the storage container 31 occurs, air can flow into the receiving space 31a through the slot 35a, so that a Pressure equalization takes place. Otherwise, the negative pressure established in the receiving space 31a could otherwise impair the functioning of the spraying device. On the other hand, the slit silicone membrane 35 is formed so that the pigmented liquid can not leak out through the slit 35a. The silicone membrane 35 thus has a double function. On the one hand it ensures the pressure equalization, on the other hand it seals against a leakage of liquid.

Die Nadel 12a ist innerhalb des Aufnahmeraums 31 a mit einer Anschlagscheibe 12c versehen, die fest an der Nadel 12a angebracht ist, beispielsweise angeklebt, aufgepresst oder angeschweißt. Zwischen der Anschlagscheibe 12c und der Teflondichtung 33 ist die als Druckfeder ausgeführte Schraubenfeder 13a eingespannt, wodurch die Nadel 12a mit ihrer Nadelspitze 12b in den Sitz 32a gedrückt wird. Bei einer Betätigung der Aufsprühvorrichtung wird die Nadel 12a gegen die Federkraft der Schraubenfeder 13a axial nach hinten gezogen, wodurch die Austrittsöffnung 32a etwas geöffnet wird.The needle 12 a is provided within the receiving space 31 a with a stop disc 12 c, which is fixedly attached to the needle 12 a, for example, glued, pressed or welded. Between the stopper disc 12c and the Teflon seal 33 is designed as a compression spring coil spring 13a clamped, whereby the needle 12a is pressed with its needle tip 12b in the seat 32a. Upon actuation of the spraying device, the needle 12a is pulled axially against the spring force of the coil spring 13a, thereby slightly opening the discharge port 32a.

Die Nadel 12a ist vorne mittels des konisch zulaufenden vorderen Endbereichs des Vorratsbehälters 31, insbesondere mittels des dort vorgesehenen Sitzes 32a, und hinten mittels der Teflondichtung 33, insbesondere mittels deren Durchgangsbohrung 33a, gerührt.The needle 12a is at the front by means of the tapered front end portion of the reservoir 31, in particular by means of the seat provided there 32a, and at the rear by means of the Teflon seal 33, in particular by means of the through hole 33a, stirred.

Zur Betätigung der Aufsprühvorrichtung ist eine lösbare formschlüssige Verbindung der Nadel 12a mit einem Betätigungsstößel 15a vorgesehen. Diese Verbindung ist zur axialen Kraftübertragung vom Betätigungsstößel 15a auf die Nadel 12a ausgestattet. Dazu weist die Nadel 12a an ihrem hinteren axialen Ende auf der vom Aufnahmeraum 31a abgewandten Seite der Teflondichtung 33 einen abgekröpften oder umgebogenen Befestigungsendabschnitt 12d auf, der im montierten Zustand in eine korrespondierende radiale Bohrung 15b des Betätigungsstößels 15a eingreift. Die Verbindung ist lösbar, beispielsweise nach Art eines Bajonettverschlusses, ausgebildet, so dass ein Austausch des die Nadel 12a umfassenden Düsenkopfs 10a möglich ist.For actuating the spraying device, a releasable positive connection of the needle 12a with an actuating tappet 15a is provided. This connection is equipped for axial power transmission from the actuating plunger 15a to the needle 12a. For this purpose, the needle 12a at its rear axial end on the side facing away from the receiving space 31a side of the Teflon seal 33 has a bent or bent attachment end portion 12d, which engages in the mounted state in a corresponding radial bore 15b of the actuating plunger 15a. The connection is detachable, for example in the manner of a bayonet closure, formed, so that an exchange of the nozzle 12a comprising the needle 12a is possible.

Der austauschbare Düsenkopf 10a umfasst neben der Nadel 12a auch den je nach aktuellem Füllzustand mehr oder weniger mit pigmentierter Flüssigkeit befüllten Vorratsbehälter 31 mit der eingesetzten Teflondichtung 33, die Schraubenfeder 13a sowie die äußere Düsenkappe 37 mit der dort eingesetzten Silikonmembran 35. Die Düsenkappe 37 ist mittels geeigneter in Fig. 2 nicht mit dargestellter Befestigungsmittel, z.B. mittels eines Bajonettverschlusses, an dem Grundkörper 1 der Aufsprühvorrichtung lösbar befestigt. Aufgrund des Vorratsbehälters 31 ist der Düsenkopf 10a mit einem integrierten Flüssigkeitstank ausgestattet. Die insbesondere als Handgerät ausgeführte erfindungsgemäße Aufsprühvorrichtung kann also unabhängig von einer externen Flüssigkeitszuführung und vor allem auch ohne einen voluminösen gesondert auf den Düsenkopf 10a aufgesetzten externen Flüssigkeitstank betrieben werden.The replaceable nozzle head 10a comprises not only the needle 12a but also depending on the current filling state more or less filled with pigmented liquid reservoir 31 with the inserted Teflon seal 33, the coil spring 13a and the outer nozzle cap 37 with the silicone membrane used there 35th Die Düsenkappe 37 ist more suitable in Fig. 2 not with fasteners shown, for example by means of a bayonet lock, releasably secured to the base body 1 of the Aufsprühvorrichtung. Due to the storage container 31, the nozzle head 10a is equipped with an integrated liquid tank. The spraying device according to the invention, which is designed in particular as a hand-held device, can thus be operated independently of an external liquid supply and, above all, without a voluminous external liquid tank placed on the nozzle head 10a separately.
