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 made in one piece. The discharge head 1 is a cap-shaped Component is and has an outer shell 2, which is substantially is cylindrical. Coaxial inside the outer jacket 2, a sleeve-shaped collar portion 3 is provided, which as well as the Outer jacket 2 is open at the bottom. The collar portion 3 serves the discharge head 1 to an outlet region, not shown a Putting the pumping unit of the metering and so the discharge head 1 to be connected to a flow path of the pump unit.

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

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. The collar portion 3 surrounds a first flow channel section a flow channel arrangement within the discharge head 1. In a upper end region is the coaxially extending first flow channel section 8 in a second, radially oriented flow channel section 6 via, to an outlet opening 4 of the discharge head. 1 leads. In front of the outlet opening 4 is an unspecified receiving area provided for a nozzle plate 9. Between the Receiving area for the nozzle disk 9 and the second flow channel section 6 is a flow guide unit in the form of a swirling arrangement 7 is provided, which is easily recognizable with reference to FIG. 1.

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.Both the receiving area and the swirling arrangement 7 have an axis of symmetry that an exit axis A of the outlet opening 4 corresponds. The exit axis A is perpendicular to a unspecified center longitudinal axis of the discharge head 1 and preferably aligned radially to this. The second flow channel section 6 opens into an upper area of the swirling arrangement 7 and the receiving area, as shown in FIG. 2 recognizable is.

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 receive a nozzle disk 9, which is designed rotationally symmetrical. The nozzle plate 9 has in the Top view of a circular shape and is in the center with a passage in the form a nozzle opening 10 is provided. The recording area is in his Dimensions matched to the nozzle plate 9, that the nozzle disc 9 in their assembled state shown in FIG. 2 flush in the receiving area sitting. In the assembled state is a nozzle axis of the nozzle opening 10 identical to the exit axis A. The nozzle disc is also mirror-symmetrical to a related to the nozzle exit axis A. aligned radial center plane.

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, the with a rounded in cross section, circumferential or circumferential Edge area is provided.

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, der als Sicherungsmittel im Sinne der Erfindung dient. 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 can be seen with reference to FIG. 1 distorted due to the selected representation is, the outlet opening 4 has a circular edge contour on. The edge contour has a diameter that is less than a diameter of the receiving area, which is a circular or has cylindrical edge contour. The edge contour of the receiving area is tuned to the diameter of the nozzle disk 9 so that the receiving area for the nozzle disk 9 a substantially ensures a play-free fit. The depth of the recording 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. To the Nozzle disk 9 without play in the receiving area, forms the peripheral edge contour of the outlet opening 4 a circumferential Rastrand 5, which serves as a securing means in the context of the invention. For mounting the nozzle disk 9, the nozzle disk 9 is in front of the Outlet opening 4 is positioned and then applying a axial pressure force pressed into the receiving area. Because the nozzle disk 9 and also the latching edge of the edge contour of the outlet opening 4 are made of plastic, is a certain elastic compliance the edge contour of the outlet opening 4 on the one hand and the edge the nozzle disc 9 on the other hand ensures, so that a pressing the nozzle disk 9 is possible. After pressing behind the engages behind Locking edge of the nozzle disk 9. The locking edge 5 thus enables the form-fitting, play-free retention of the nozzle disk 9. The positive locking Restraining forces which the locking rim 5 exerts on the nozzle disk 9, causes a circumferential sealing function, so that the nozzle plate 9 sealed is held in the receiving area. Liquid can therefore only pass through the central nozzle opening 10 to the outside. Incidentally, the form-fitting retention forces are dimensioned so great that that no pushing out of the nozzle disk 9 under strong Overpressure promoted liquid medium within the two flow channel sections 6, 8 is made possible 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 essentially corresponds to the discharge head according to FIGS. 1 and 2. Except for the differences described below, the entire applies Revelation of the embodiment of the discharge head 1 according to Figs. 1 and 2 for the discharge head 1a. Function equal or identical components or sections of the discharge head 1a are identical Reference numerals as in the discharge head 1 according to FIG. 1 and 2, but with the addition of the letter a. essential The difference in the discharge head 1a is that of the swirling arrangement 7a and the second flow channel section 6a subsequent receiving area for receiving the nozzle disk 9 directly on the outside of the outer shell 2a of the discharge head 1a is arranged. The outlet opening 4a is in a separate securing component provided in the form of a sleeve-like securing hood 5a, the non-positively from above via the discharge head 1a or outer jacket 2a is pushed. The outlet opening 4a has a much smaller diameter than the receiving area for the Nozzle disk 9 on. The outlet opening 4a becomes coaxial in front of the nozzle axis the nozzle disk 9 is positioned. A circumferential edge contour of Outlet opening 4a thus necessarily serves as a peripheral edge projection, the positive retention of the nozzle disk 9 in the Recording area causes.

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 as the outer diameter of the outer shell 2a, so that a safer Frictional connection of the safety hood 5a in its on the outer sheath 2a plugged state is ensured.

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 the safety hood 5a with respect to the outer jacket of the discharge head to twist. This allows the outlet opening in one with the nozzle opening of the nozzle plate aligned position or in a be rotated relative to the nozzle disc rotated position. In the twisted position obscured a shell portion of the safety hood the nozzle disc completely, so that no discharge process is possible. Once the outlet opening in the aligned with the nozzle disc position is twisted, a corresponding spraying process can take place.

Bei einem weiteren, nicht dargestellten Ausführungsbeispiel der Erfindung weist die Sicherungshaube keinerlei Sicherungsfunktion auf, sondern ist ausschließlich ein dekoratives Bauteil.In a further, not shown embodiment of the invention the safety hood has no safety function, but is exclusively a decorative component.

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, not shown embodiment of the invention have the outer jacket of the discharge head and the safety hood each have a polygonal outer contour. These polygonal outer contours Ensure that the safety cap fits accurately the outer sheath can be attached 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 disc.

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 when placing on the outer shell only a portion of the Outer shell covered by the nozzle disc or the outlet opening the discharge head is positioned. Such a security component can then in particular a half shell shape or a similar, rotationally asymmetric Represent component.
