A lateral radial duct (6) leads to a spray chamber with a lipped (5) outer aperture into which is clipped a plastic jet disc (9) with a central spray aperture (10). The disc is symmetric and can be fitted either way round. The outer edge of the disc is curved and sits behind the retaining lip. The inside of the disc presses onto a swirl insert (7). The construction of the disc and mounting is sufficiently strong to accommodate the maximum pump pressures.

Description

Die Erfindung betrifft einen Austragkopf für eine Dosiereinrichtung nach dem Oberbegriff von Anspruch 1.The invention relates to a discharge head for a metering device according to the preamble of claim 1.

Ein Austragkopf für eine Dosiereinrichtung zur Ausbringung eines Mediums ist aus der DE 198 13 078 A1 bekannt. Der Austragkopf besteht aus Kunststoff und ist mit einer integrierten Strömungskanalanordnung versehen. Durch Aufstecken des Austragkopfes auf eine Pumpeinheit kann die Strömungskanalanordnung mit einem Strömungsweg der Pumpeinheit verbunden werden. Die Strömungskanalanordnung weist einen radial zu einer Mittellängsachse des Austragkopfes verlaufenden Strömungskanalabschnitt auf, der in eine Drallgebungseinheit mündet, die als Strömungsleiteinheit für das ausströmende Medium dient. Die Drallgebungseinheit ist einstückig in dem kappenförmig gestalteten Austragkopf ausgeformt. Vor einer Austrittsöffnung des Austragkopfes, die auf die Drallgebungseinheit folgt, ist ein mit einer Austrittsdüse versehenes Schieberbauteil angeordnet, das ein separates Düsenbauteil darstellt. Das Schieberbauteil ist aus Kunststoff hergestellt und vorzugsweise einstückig und gemeinsam mit dem Austragkopf hergestellt. In einer Ruheposition, die nach der Herstellung der Bauteile definiert ist, ist das Schieberbauteil über feinste Spritzgussverbindungen eingangsseitig einer quer zur Strömungskanalanordnung verlaufenden und als Aufnahme dienenden Schiebenut gehalten. Durch ein Nachuntendrücken des Schieberbauteiles werden die feinen Verbindungen getrennt, so dass das Schieberbauteil in der Schiebenut nach unten verschiebbar ist, wodurch die in dem Schieberbauteil integrierte Austrittsdüse vor der Drallgebungseinheit positioniert wird. Der Austragkopf befindet sich nun in einer Funktionsposition, in der bei einem Aufsetzen des Austragkopfes auf die Pumpeinheit ein Austragvorgang des insbesondere flüssigen Mediums, vorzugsweise ein Sprühvorgang, erfolgen kann.A discharge head for a metering device for applying a medium is known from DE 198 13 078 A1 known. The discharge head is made of plastic and is provided with an integrated flow channel arrangement. By attaching the discharge head to a pump unit, the flow channel arrangement can be connected to a flow path of the pump unit. The flow channel arrangement has a flow channel section extending radially to a central longitudinal axis of the discharge head, which opens into a swirling unit which serves as a flow-guiding unit for the outflowing medium. The swirling unit is formed integrally in the cap-shaped discharge head. In front of an outlet opening of the discharge head, which follows the swirling unit, is provided with an outlet nozzle Slider member arranged, which represents a separate nozzle member. The slide member is made of plastic and preferably made in one piece and together with the discharge head. In a rest position, which is defined after the manufacture of the components, the slider component via the finest injection-molding compounds on the input side of a transverse to the flow channel arrangement and serving as a recording slide groove is held. By pushing the slide component downwards, the fine connections are separated, so that the slide component can be displaced downwards in the slide groove, whereby the outlet nozzle integrated in the slide component is positioned in front of the swirling unit. The discharge head is now in a functional position in which a discharge operation of the particular liquid medium, preferably a spraying, can take place when the discharge head is placed on the pump unit.

Aus der US 3,192,611 ist ein gattungsgemäßer Austragkopf bekannt, in dessen Austragöffnung eine separate Düsenscheibe vorgesehen ist. Diese ist in einer dafür vorgesehenen Aufnahme formschlüssig gehalten. Zum Zwecke der Montage wird diese Düsenscheibe in elastisch verformtem Zustand mit einem Stempel in die Aufnahme hineingedrückt.From the US 3,192,611 is a generic discharge known, in the discharge a separate nozzle disk is provided. This is held positively in a receptacle provided for this purpose. For the purpose of assembly, this nozzle disk is pressed into an elastically deformed state with a punch in the receptacle.

Aufgabe der Erfindung ist es, einen Austragkopf der eingangs genannten Art zu schaffen, der äußerst kleinbauend gestaltet werden kann und in einfacher Weise herstellbar ist.The object of the invention is to provide a discharge head of the type mentioned, which can be designed extremely kleinbauend and can be produced in a simple manner.

Diese Aufgabe wird durch einen Austragkopf für eine Dosiereinrichtung mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a discharge head for a metering device having the features of claim 1.

Durch die erfindungsgemäße Lösung ist es in äußerst einfacher Weise möglich, das Düsenbauteil in der Aufnahme des Austragkopfes zu montieren und so einen funktionsfertigen Austragkopf zu erreichen. Die scheibenförmige und symmetrisch zu der Düsenaustrittsachse erfolgende Gestaltung des Düsenbauteiles ermöglicht eine ungerichtete Montage des Düsenbauteiles. Dies bedeutet, dass das Düsenbauteil in beliebiger Position in die Aufnahme einsetzbar ist und ohne eine anschließende Ausrichtung bereits mit dem Einsetzen die gewünschte Endposition erreicht hat. Vorzugsweise ist die Aufnahme in ihren Abmessungen derart an das Düsenbauteil angepasst, dass das Düsenbauteil bündig in die Aufnahme einsetzbar ist. Die erfindungsgemäße Lösung eignet sich insbesondere für Dosiereinrichtungen, die flüssige Medien austragen. Vorzugsweise ist das Düsenbauteil derart ausgestaltet, dass das Düsenbauteil gemeinsam mit der Strömungsleiteinheit und dem Düsenaustritt eine Sprühdüse definiert. Grundsätzlich ist es aber auch möglich, andere Arten von fließ-, riesel- oder schüttfähigen oder auch gasförmigen Medien auszutragen.The solution according to the invention makes it possible in an extremely simple manner to mount the nozzle component in the receptacle of the discharge head and thus to achieve a functioning discharge head. The disk-shaped and symmetrical to the nozzle exit axis taking place Design of the nozzle component allows an undirected mounting of the nozzle member. This means that the nozzle component can be used in any position in the recording and without subsequent alignment has reached the desired end position with the insertion. Preferably, the receptacle is adapted in its dimensions to the nozzle component in such a way that the nozzle component can be inserted flush into the receptacle. The solution according to the invention is particularly suitable for metering devices which discharge liquid media. The nozzle component is preferably configured such that the nozzle component defines a spray nozzle together with the flow-guiding unit and the nozzle outlet. In principle, it is also possible to discharge other types of free-flowing, free-flowing or free-flowing or gaseous media.

Besonders geeignet ist die erfindungsgemäße Lösung für den Einsatz im Kosmetikbereich oder im pharmazeutischen Bereich. Bei der erfindungsgemäßen Lösung sind insbesondere besonders kleinbauende Austragköpfe erzielbar. Besonders vorteilhaft ist die Erfindung für Dosierpumpen einsetzbar, die einen Pumpendurchmesser von weniger als 9 mm aufweisen. Hier handelt es sich um miniaturisierte Dosierpumpen. In entsprechender Weise ist vorzugsweise auch der Austragkopf mit einem Durchmesser versehen, der kleiner als 9 mm ausgeführt ist.The solution according to the invention is particularly suitable for use in the cosmetics sector or in the pharmaceutical sector. In the solution according to the invention particularly particularly small-sized discharge heads can be achieved. The invention can be used particularly advantageously for metering pumps which have a pump diameter of less than 9 mm. These are miniaturized dosing pumps. In a corresponding manner, the discharge head is preferably also provided with a diameter which is smaller than 9 mm.

In Ausgestaltung der Erfindung ist vorgesehen, dass die Aufnahme koaxial zu der Düsenaustrittsachse derart nach außen offen gestaltet ist, dass das Düsenbauteil längs der Düsenaustrittsachse in der Aufnahme montierbar ist. Das Einsetzen des Düsenbauteiles längs der Düsenaustrittsachse in der Aufnahme ermöglicht vorteilhaft in einem einzigen Arbeitsschritt bereits eine exakte und endgültige Positionierung des Düsenbauteiles in der Aufnahme und damit in dem Austragkopf.In an embodiment of the invention, it is provided that the receptacle is designed coaxially to the nozzle exit axis open to the outside so that the nozzle member along the nozzle exit axis in the receptacle can be mounted. The insertion of the nozzle component along the nozzle exit axis in the receptacle advantageously allows in a single step already an exact and final positioning of the nozzle member in the receptacle and thus in the discharge head.

In weiterer Ausgestaltung der Erfindung ist das scheibenförmige Düsenbauteil rotationssymmetrisch zu der Düsenaustrittsachse gestaltet. Dadurch ergibt sich insbesondere eine flache zylindrische Scheibe, die vorzugsweise in ihrer Mitte koaxial zur Düsenaustrittsachse eine entsprechende Düsenöffnung aufweist.In a further embodiment of the invention, the disc-shaped nozzle member is designed rotationally symmetrical to the nozzle exit axis. This results in particular a flat cylindrical disk, which preferably has a corresponding nozzle opening coaxial with the nozzle exit axis in its center.

In weiterer Ausgestaltung der Erfindung ist das Düsenbauteil spiegelsymmetrisch zu einer auf die Düsenaustrittsachse bezogenen radialen Mittelebene gestaltet. Dadurch ist es möglich, das Düsenbauteil sowohl in einer ersten Ausrichtung als auch in einer zweiten, spiegelverkehrten Ausrichtung in die Aufnahme einzusetzen und dennoch in beiden Fällen die gleiche Düsenfunktion zu erzielen.In a further embodiment of the invention, the nozzle member is designed mirror-symmetrically to a related to the nozzle exit axis radial center plane. This makes it possible to use the nozzle member both in a first orientation and in a second, mirror-inverted orientation in the recording and still achieve the same nozzle function in both cases.

Erfindungsgemäß sind der Aufnahme Sicherungsmittel zum Fixieren des Düsenbauteiles in der Aufnahme zugeordnet. Die Sicherungsmittel dienen dazu, das Düsenbauteil form- oder kraftschlüssig in der Aufnahme zu fixieren.
Als Sicherungsmittel ist dabei ein separates Sicherungsbauteil vorgesehen, das mit dem Austragkopf verbindbar ist und in seiner Sicherungsposition das Düsenbauteil form- oder kraftschlüssig in der Aufnahme zurückhält. Das Sicherungsbauteil ist vorzugsweise kappen- oder hülsenartig gestaltet und auf den Austragkopf aufsteckbar oder aufschiebbar. Vorzugsweise kann das kappen- oder hülsenförmige Sicherungsbauteil eine Durchtrittsöffnung aufweisen, deren Durchmesser geringfügig größer ist als ein Durchmesser des Düsenaustrittes. Vorzugsweise ist das Sicherungsbauteil bei seiner Montage auf dem Austragkopf derart geführt, dass die Durchtrittsöffnung zwangsläufig koaxial zu dem Düsenaustritt positioniert wird. Alternativ ist es möglich, sowohl eine Außenkontur des Austragkopfes als auch das Sicherungsbauteil rotationssymmetrisch zu gestalten, so dass das Sicherungsbauteil relativ zu dem Austragkopf verdreht werden kann. Dadurch kann die Durchtrittsöffnung entweder koaxial vor dem Düsenaustritt gedreht werden, oder aber die Durchtrittsöffnung wird bei Nichtbenutzung so verdreht, dass die Durchtrittsöffnung zu dem Düsenaustritt versetzt ist. In dieser Position verschließt ein entsprechender Mantelabschnitt des Sicherungsbauteiles den Düsenaustritt. In besonders bevorzugter Weise ist das Sicherungsbauteil bei der beschriebenen Ausführung als Außenhülse gestaltet, die den Austragkopf wenigstens im Bereich der Aufnahme außen übergreift.According to the invention, securing means for fixing the nozzle component in the receptacle are associated with the receptacle. The securing means serve to fix the nozzle member positively or non-positively in the receptacle.
As a securing means, a separate securing component is provided, which is connectable to the discharge head and in its securing position, the nozzle member positively or non-positively retains in the recording. The securing component is preferably designed cap or sleeve-like and can be plugged or pushed onto the discharge head. Preferably, the cap or sleeve-shaped securing member may have a passage opening whose diameter is slightly larger than a diameter of the nozzle outlet. Preferably, the securing component is guided during its assembly on the discharge head such that the passage opening is necessarily positioned coaxially with the nozzle exit. Alternatively, it is possible to make both an outer contour of the discharge head and the securing component rotationally symmetrical, so that the securing member can be rotated relative to the discharge head. Thereby, the passage opening can be rotated either coaxially in front of the nozzle outlet, or the Passage opening is rotated when not in use so that the passage opening is offset to the nozzle outlet. In this position, a corresponding skirt portion of the securing component closes the nozzle outlet. In a particularly preferred manner, the securing component is designed in the described embodiment as an outer sleeve which engages over the discharge head at least in the region of the receptacle outside.

Particularly preferably, the discharge head 1 according to the Fig. 1 and 2 an actual diameter of less than 9 mm. With these small dimensions is the discharge head 1 advantageously part of a miniaturized metering device, since the other parts of the metering device preferably have no larger diameter than the discharge head. 1

Der Austragkopf 1 ist aus einem thermoplastischen Kunststoff im Spritzgussverfahren einstückig hergestellt. Der Austragkopf 1 stellt ein kappenförmiges Bauteil dar und weist einen Außenmantel 2 auf, der im wesentlichen zylindrisch gestaltet ist. Koaxial innerhalb des Außenmantels 2 ist ein hülsenförmiger Kragenabschnitt 3 vorgesehen, der wie auch der Außenmantel 2 nach unten offen ist. Der Kragenabschnitt 3 dient dazu, den Austragkopf 1 auf einen nicht dargestellten Auslassbereich einer Pumpeinheit der Dosiereinrichtung aufzustecken und so den Austragkopf 1 mit einem Strömungsweg der Pumpeinheit zu verbinden.The discharge head 1 is made of a thermoplastic material by injection molding in one piece. The discharge head 1 is a cap-shaped component and has an outer shell 2, which is designed substantially cylindrical. Coaxially within the outer shell 2, a sleeve-shaped collar portion 3 is provided which, like the outer shell 2, is open at the bottom. The collar portion 3 serves to attach the discharge head 1 to an outlet region, not shown, of a pumping unit of the metering device and thus to connect the discharge head 1 to a flow path of the pumping unit.

Die Dosiereinrichtung weist zusätzlich zu der Pumpeinheit vorzugsweise einen Mediumspeicher auf.The metering device preferably has a medium reservoir in addition to the pumping unit.

Der Kragenabschnitt 3 umgibt einen ersten Strömungskanalabschnitt einer Strömungskanalanordnung innerhalb des Austragkopfes 1. In einem oberen Endbereich geht der koaxial verlaufende erste Strömungskanalabschnitt 8 in einen zweiten, radial ausgerichteten Strömungskanalabschnitt 6 über, der zu einer Austrittsöffnung 4 des Austragkopfes 1 führt. Vor der Austrittsöffnung 4 ist ein nicht näher bezeichneter Aufnahmebereich für eine Düsenscheibe 9 vorgesehen. Zwischen dem Aufnahmebereich für die Düsenscheibe 9 und dem zweiten Strömungskanalabschnitt 6 ist eine Strömungsleiteinheit in Form einer Drallgebungsanordnung 7 vorgesehen, die anhand der Fig. 1 gut erkennbar ist. Sowohl der Aufnahmebereich als auch die Drallgebungsanordnung 7 weisen eine Symmetrieachse auf, die einer Austrittsachse A der Austrittsöffnung 4 entspricht. Die Austrittsachse A ist rechtwinklig zu einer nicht näher bezeichneten Mittellängsachse des Austragkopfes 1 und vorzugsweise radial zu dieser ausgerichtet. Der zweite Strömungskanalabschnitt 6 mündet in einem oberen Bereich der Drallgebungsanordnung 7 und des Aufnahmebereiches, wie anhand der Fig. 2 erkennbar ist.The collar section 3 surrounds a first flow channel section of a flow channel arrangement within the discharge head 1. In an upper end region, the coaxially extending first flow channel section 8 merges into a second, radially aligned flow channel section 6, which leads to an outlet opening 4 of the discharge head 1. In front of the outlet opening 4, an unspecified receiving area for a nozzle disk 9 is provided. Between the receiving area for the nozzle disk 9 and the second flow channel section 6, a flow-guiding unit in the form of a swirl arrangement 7 is provided, which is based on the Fig. 1 is clearly recognizable. Both the receiving area and the swirling arrangement 7 have an axis of symmetry which corresponds to an exit axis A of the exit opening 4. The exit axis A is at right angles to an unspecified center longitudinal axis of the discharge head 1 and preferably aligned radially thereto. The second flow channel section 6 opens in an upper region of the swirling arrangement 7 and the receiving area, as shown in FIG Fig. 2 is recognizable.

Der Aufnahmebereich dient dazu, eine Düsenscheibe 9 aufzunehmen, die rotationssymmetrisch gestaltet ist. Die Düsenscheibe 9 weist in der Draufsicht eine Kreisform auf und ist mittig mit einem Durchtritt in Form einer Düsenöffnung 10 versehen. Der Aufnahmebereich ist in seinen Abmessungen so auf die Düsenscheibe 9 abgestimmt, dass die Düsenscheibe 9 in ihrem montierten Zustand gemäß Fig. 2 bündig in dem Aufnahmebereich sitzt. Im montierten Zustand ist eine Düsenachse der Düsenöffnung 10 identisch mit der Austrittsachse A. Die Düsenscheibe ist zudem spiegelsymmetrisch zu einer auf die Düsenaustrittsachse A bezogenen radialen Mittelebene ausgerichtet.The receiving area serves to accommodate a nozzle disk 9, which is designed rotationally symmetrical. The nozzle disk 9 has a circular shape in plan view and is provided centrally with a passage in the form of a nozzle opening 10. The receiving area is matched in its dimensions to the nozzle plate 9 that the nozzle plate 9 in its assembled state according to Fig. 2 sits flush in the receiving area. In the assembled state, a nozzle axis of the nozzle opening 10 is identical to the exit axis A. The nozzle plate is also mirror-symmetrically aligned with respect to a radial center plane related to the nozzle exit axis A.

Die Düsenscheibe 9 ist als einstückiger Kunststoffkörper ausgeführt, der mit einem im Querschnitt abgerundeten, umlaufenden Umfangs- oder Randbereich versehen ist.The nozzle plate 9 is designed as a one-piece plastic body, which is provided with a rounded in cross section, peripheral peripheral or edge region.

Wie anhand der Fig. 1 aufgrund der gewählten Darstellung verzerrt erkennbar ist, weist die Austrittsöffnung 4 eine kreisförmige Randkontur auf. Die Randkontur weist einen Durchmesser auf, der geringer ist als ein Durchmesser des Aufnahmebereiches, der eine kreisförmige oder zylindrische Randkontur besitzt. Die Randkontur des Aufnahmebereiches ist auf den Durchmesser der Düsenscheibe 9 so abgestimmt, dass der Aufnahmebereich für die Düsenscheibe 9 einen im wesentlichen spielfreien Sitz gewährleistet. Die Tiefe des Aufnahmebereiches ist ebenfalls auf die Dicke der Düsenscheibe 9 abgestimmt, so dass die Düsenscheibe 9 axial bündig in dem Aufnahmebereich gehalten ist. Um die Düsenscheibe 9 spielfrei in dem Aufnahmebereich zurückzuhalten, bildet die umlaufende Randkontur der Austrittsöffnung 4 einen umlaufenden Rastrand 5. Zum Montieren der Düsenscheibe 9 wird die Düsenscheibe 9 vor der Austrittsöffnung 4 positioniert und anschließend unter Aufbringung einer axialen Druckkraft in den Aufnahmebereich hineingepresst. Da die Düsenscheibe 9 und auch der Rastrand der Randkontur der Austrittsöffnung 4 aus Kunststoff bestehen, ist eine gewisse elastische Nachgiebigkeit der Randkontur der Austrittsöffnung 4 einerseits und des Randes der Düsenscheibe 9 andererseits gewährleistet, so dass ein Einpressen der Düsenscheibe 9 ermöglicht ist. Nach dem Einpressen hintergreift der Rastrand die Düsenscheibe 9. Der Rastrand 5 ermöglicht so den formschlüssigen, spielfreien Rückhalt der Düsenscheibe 9. Die formschlüssigen Rückhaltekräfte, die der Rastrand 5 auf die Düsenscheibe 9 ausübt, bewirkt eine umlaufende Dichtfunktion, so dass die Düsenscheibe 9 abgedichtet in dem Aufnahmebereich gehalten ist. Flüssigkeit kann daher ausschließlich durch die zentrale Düsenöffnung 10 nach außen treten. Die formschlüssigen Rückhaltekräfte sind im Übrigen so groß bemessen, dass kein Herausdrücken der Düsenscheibe 9 bei unter starkem Überdruck gefördertem flüssigem Medium innerhalb der beiden Strömungskanalabschnitte 6, 8 zu der Austrittsöffnung 4 ermöglicht ist.As based on the Fig. 1 is distorted recognizable due to the selected representation, the outlet opening 4 has a circular edge contour. The edge contour has a diameter which is smaller than a diameter of the receiving area, which has a circular or cylindrical edge contour. The edge contour of the receiving area is matched to the diameter of the nozzle disk 9 so that the receiving area for the nozzle disk 9 ensures a substantially backlash-free seat. The depth of the receiving area is also matched to the thickness of the nozzle disk 9, so that the nozzle disk 9 is held axially flush in the receiving area. In order to retain the nozzle disk 9 without play in the receiving area, the peripheral edge contour of the outlet opening 4 forms a circumferential latching edge 5. For mounting the nozzle disk 9, the nozzle disk is formed 9 positioned in front of the outlet opening 4 and then pressed into the receiving area while applying an axial compressive force. Since the nozzle disk 9 and also the latching edge of the edge contour of the outlet opening 4 are made of plastic, a certain elastic compliance of the edge contour of the outlet opening 4 on the one hand and the edge of the nozzle disk 9 on the other hand ensured, so that an injection of the nozzle plate 9 is possible. The latching rim 5 thus engages behind the positive, backlash-free retention of the nozzle disk 9. The form-fitting retaining forces which the latching rim 5 exerts on the nozzle disk 9 cause a peripheral sealing function, so that the nozzle disk 9 is sealed in FIG the recording area is held. Liquid can therefore only pass out through the central nozzle opening 10 to the outside. Incidentally, the positive retaining forces are dimensioned so large that no pushing out of the nozzle disk 9 is made possible with the liquid medium conveyed under strong overpressure within the two flow channel sections 6, 8 to the outlet opening 4.

Bei der Ausführungsform nach Fig. 3 ist ein Austragkopf 1a vorgesehen, der im wesentlichen dem Austragkopf gemäß den Fig. 1 und 2 entspricht. Bis auf die nachfolgend beschriebenen Unterschiede gilt die gesamte Offenbarung der Ausführungsform der Austragkopfes 1 gemäß den Fig. 1 und 2 auch für den Austragkopf 1a. Funktionsgleiche oder identische Bauteile oder Abschnitte des Austragkopfes 1a sind mit identischen Bezugszeichen wie bei dem Austragkopf 1 gemäß den Fig. 1 und 2 versehen, jedoch unter Hinzufügung des Buchstaben a. Wesentlicher Unterschied bei dem Austragkopf 1a ist es, dass der an die Drallgebungsanordnung 7a und den zweiten Strömungskanalabschnitt 6a anschließende Aufnahmebereich zum Aufnehmen der Düsenscheibe 9 unmittelbar außenseitig des Außenmantels 2a des Austragkopfes 1a angeordnet ist. Die Austrittsöffnung 4a ist in einem separaten Sicherungsbauteil in Form einer hülsenartigen Sicherungshaube 5a vorgesehen, die kraftschlüssig von oben her über den Austragkopf 1a bzw. Außenmantel 2a geschoben ist. Die Austrittsöffnung 4a weist einen wesentlich geringeren Durchmesser als der Aufnahmebereich für die Düsenscheibe 9 auf. Die Austrittsöffnung 4a wird koaxial vor der Düsenachse der Düsenscheibe 9 positioniert. Eine umlaufende Randkontur der Austrittsöffnung 4a dient somit zwangsläufig als umlaufender Randvorsprung, der den formschlüssigen Rückhalt der Düsenscheibe 9 in dem Aufnahmebereich bewirkt.In the embodiment according to Fig. 3 a discharge head 1a is provided, which is substantially the discharge head according to the Fig. 1 and 2 equivalent. Except for the differences described below, the entire disclosure of the embodiment of the discharge head 1 according to the Fig. 1 and 2 also for the discharge head 1a. Functionally identical or identical components or portions of the discharge head 1a are denoted by identical reference numerals as in the discharge head 1 according to the Fig. 1 and 2 but with the addition of the letter a. The essential difference in the discharge head 1a is that the receiving region adjoining the swirl arrangement 7a and the second flow channel section 6a for receiving the nozzle disk 9 is arranged directly outside the outer casing 2a of the discharge head 1a. The outlet opening 4a is in a separate securing component provided in the form of a sleeve-like securing hood 5a, which is frictionally pushed from above via the discharge head 1a and outer casing 2a. The outlet opening 4a has a substantially smaller diameter than the receiving area for the nozzle disk 9. The outlet opening 4a is positioned coaxially in front of the nozzle axis of the nozzle disk 9. A circumferential edge contour of the outlet opening 4a thus serves necessarily as a peripheral edge projection, which causes the positive retention of the nozzle disk 9 in the receiving area.

Der Innendurchmesser der Sicherungshaube 5a ist geringfügig kleiner als der Außendurchmesser des Außenmantels 2a, so dass ein sicherer Kraftschluss der Sicherungshaube 5a in ihrem auf den Außenmantel 2a aufgesteckten Zustand gewährleistet ist.The inner diameter of the securing hood 5a is slightly smaller than the outer diameter of the outer jacket 2a, so that a secure adhesion of the securing hood 5a is ensured in its mounted on the outer jacket 2a state.

Bei nicht dargestellten Ausführungsbeispielen der Erfindung ist es möglich, die Sicherungshaube 5a gegenüber dem Außenmantel des Austragkopfes zu verdrehen. Dadurch kann die Austrittsöffnung in eine mit der Düsenöffnung der Düsenscheibe fluchtende Position oder in eine relativ zu der Düsenscheibe verdrehte Position gebracht werden. In der verdrehten Position verdeckt ein Mantelabschnitt der Sicherungshaube die Düsenscheibe vollständig, so dass kein Austragvorgang möglich ist. Sobald die Austrittsöffnung in die mit der Düsenscheibe fluchtende Position verdreht ist, kann ein entsprechender Sprühvorgang stattfinden.In non-illustrated embodiments of the invention, it is possible to rotate the securing cap 5a relative to the outer shell of the discharge head. As a result, the outlet opening can be brought into a position aligned with the nozzle opening of the nozzle disk or into a position rotated relative to the nozzle disk. In the twisted position, a jacket portion of the securing hood completely covers the nozzle disk, so that no discharge process is possible. As soon as the outlet opening is rotated into the position aligned with the nozzle disk, a corresponding spraying process can take place.

Bei einem weiteren, nicht dargestellten Ausführungsbeispiel der Erfindung weisen der Außenmantel des Austragkopfes und die Sicherungshaube jeweils eine polygonale Außenkontur auf. Diese polygonalen Außenkonturen gewährleisten, dass die Sicherungshaube passgenau auf den Außenmantel aufsteckbar ist und anschließend nicht verdreht werden kann. Das Aufstecken erfolgt derart gerichtet, dass zwangsläufig die Austrittsöffnung fluchtend vor der Düsenscheibe positioniert wird.In a further embodiment of the invention, not shown, the outer jacket of the discharge head and the securing hood each have a polygonal outer contour. These polygonal outer contours ensure that the safety hood can be snapped onto the outer sheath and then not twisted can. The plugging is done in such a way that inevitably the outlet opening is positioned in alignment in front of the nozzle disk.

Es ist auch möglich, dass das Sicherungsbauteil so ausgeführt ist, dass es beim Aufsetzen auf den Außenmantel lediglich einen Teilbereich des Außenmantels überdeckt, indem die Düsenscheibe bzw. die Austrittsöffnung des Austragkopfes positioniert ist. Ein derartiges Sicherungsbauteil kann dann insbesondere eine Halbschalenform oder ein ähnliches, rotationsasymmetrisches Bauteil darstellen.It is also possible that the securing component is designed so that it covers only a portion of the outer shell when placed on the outer shell, by the nozzle disk and the outlet opening of the discharge head is positioned. Such a security component can then represent in particular a half shell shape or a similar rotationally asymmetric component.
