Definitions
- the invention relates to an output device for spraying a sprayable fluid, which is designed as a hand-held device.
- a so-called airbrush system for applying make-up.
- Such devices are used by professional make-up artists. These have a compressor and several hose lines, which remove the respective make-up from individual stores of different make-ups and discharge them via a common spray nozzle. They are cleaned after each use so that they are available for subsequent use.
- airbrush systems are not suitable for being carried in a handbag, so that, for example, the make-up can be applied or refreshed quickly.
- an output device is known as a hand-held device, which comprises a motor and an air pump which is driven by the motor in a housing. Furthermore, a storage container for the fluid to be applied is arranged in the hand-held device. The air and the fluid to be dispensed are mixed in a mixing chamber of the spray head and dispensed through a nozzle.
- the problem with such handheld devices is that they become inoperable very quickly since the fluid to be dispensed has dried out.
- the application of the medium to be dispensed, in particular make-up is often uneven, which makes handling more difficult.
- the invention has for its object to provide an output device for spraying a sprayable fluid, which is designed as a handheld device and has an improved functionality.
- the spray head has a first nozzle connected to a fluid line and separately a second nozzle in the spray head, and the first nozzle is supplied with the air flow from a hose line connected to the first nozzle and the nozzle opening of the first Nozzle protrudes at least slightly into the air flow emerging from the second nozzle. This enables the medium supplied through the first nozzle to be atomized.
- a preferred embodiment of the dispensing device provides that the discharge direction of the first nozzle for discharging the air flow and the discharge direction of the second nozzle, via which the fluid is discharged, are oriented at an angle of 90 ° to one another or at an angle of less than 90 ° are aligned with each other.
- Such an alignment of the two nozzles relative to one another, or of the two nozzle channels, enables particularly preferred atomization.
- the fluid is conveyed out of the second nozzle according to the Venturi principle by the air flow emerging from the first nozzle.
- a preferred embodiment of the dispensing device provides that the spray head can be arranged on a detachable closure of the storage container.
- the spray head can be flange-mounted, screwed on, clipped on or clamped on.
- the spray head is integrated in one piece on the closure of the storage container.

- the drive motor 18 drives an air pump 22. This is supplied with air through inlet openings 23 in the housing wall of the housing 12. One or more air inlet openings 23 can be provided in the housing wall.
- the air pump 22 includes an outlet port 25 through which an air flow generated by the air pump 22 is output.
- a branch 26, for example, can be connected to this outlet connection 25, through which the air flow generated is divided. This can be transferred into a pressure line 28, which leads into a receiving space 29 in the housing 12.
- the pressure line 28 is preferably fastened to the bottom 32 of the receiving space 29 by means of a connecting piece 31 and has an inlet opening 34 which opens into the receiving space 29.
- the air flow generated by the air pump 22 can furthermore be converted into a hose line 36 by means of the branch 26.
- This hose line 36 leads into the spray head 14 and ends in a nozzle 38 for outputting the air flow.
- a storage container 41 can be inserted into the receiving space 29 of the housing 12. This reservoir 41 receives the sprayable fluid, in particular make-up.
- the storage container 41 On the output side, the storage container 41 has a closure 42, which is preferably designed as a self-healing closure.
- a fluid line 44 can be connected to this closure 42.
- the fluid line 44 preferably includes a needle 45 facing the closure 42, so that after the storage container 41 has been inserted into the receiving space 29 and a subsequent closing movement of the spray head 14 to the housing 12, the needle 45 of the fluid line 44 engages in the closure 42 and the output of the allows sprayable fluids.
- the fluid line 44 has a nozzle 46 opposite the needle 45.
- This nozzle 46 for dispensing the fluid is provided separately from the nozzle 38 for dispensing the air flow to the spray head 14.
- the nozzles 38, 46 are designed as tubes. Atomizing the Fluids take place in an atomizing zone 49 of the spray head 14, which is, for example, funnel-shaped, bell-shaped or the like.
- an air pressure regulator 51 is preferably provided, which can be adjusted via an operating element or adjusting element 52, in particular an adjusting wheel.
- Such an air regulator 51 with an actuating element 52 is advantageously also provided in the pressure line 28.
- the receiving space 29 is part of a housing wall or adjoins a housing wall, the housing 12 advantageously comprising a viewing window 54 in the region of the storage container 41 in order to be able to recognize the filling level in the storage container 41.
- the reservoir 41 according to Figure 1 is designed as a cartridge, which comprises a cartridge base 56 with a connection opening 57, which can be connected, in particular latched or clipped, to the connector 31 after the storage container 41 has been inserted into the receiving space 29.
- a displaceable base 59 is preferably provided in the storage container 41, which has a sealing lip 61 on its outside for sealing an interior 62.
- the floor 59 has a curvature 63 which is oriented toward the interior 62.
- the control button 21 is actuated to dispense the sprayable fluid.
- the drive motor 18 is energized by the accumulator 19.
- the drive motor 18 drives the air pump 22, whereby an air flow is generated.
- the mass flow of the air flow is conducted via the pressure line 28 into the storage container 41, as a result of which an overpressure is built up between the cartridge base 56 and the displaceable base 49.
- the displaceable bottom 59 is displaced in the direction of the closure 42.
- the fluid is guided via the fluid line 44 to the nozzle 46 and dispensed.
- the second mass flow Air flow passed through the hose line 36 to the nozzle 38 and output.
- the fluid is atomized in the atomizing zone 49, as a result of which the sprayable fluid is sprayed in the discharge direction according to arrow 65.
- the fluid space is equalized again in terms of pressure.
- the drive motor 18 switches off.
- the pressure between the cartridge base 56 and the displaceable base 59 is reduced.
- the displaceable bottom 59 returns to its starting position, as a result of which a slight negative pressure is generated in the storage container 41, through which the fluid in the fluid line 44 is sucked back into the interior 62 of the storage container 41.
- the fluid line 44 is many times shorter than the hose line 36. As a result, the small amount that accumulates in the fluid line 44 is returned to the storage container 41 after the drive motor 18 has been switched off, in order to prevent the fluid line from drying out.
- the spray head 14 is opened, as shown by the arrow 67 in Figure 2 is shown.
- a protective device 71 is activated which surrounds the needle 45 in order to avoid the risk of injury.
- the protective device 71 can be transferred into the protective position by means of an energy storage element 72.
- the spray head 14 is fed onto the housing 12 and the protective device 71 is returned to an initial position by contact, for example, with the closure 42 or a further stop element on the housing 12.
- the dispensing device 11 is designed to receive a storage container 41 designed as a tubular bag.
- This arrangement differs from that in Figure 1 in that the Receiving space 29 is sealed airtight after insertion of the tubular bag or the tubular bag is fastened to an upper edge of the receiving space 29 in such a way that a closed space is created between the bottom 32 of the receiving space 29 and the inserted tubular bag. As a result, a pressure can again be built up in the receiving space 29 in order to discharge the fluid from the tubular bag.
- the spray head 14 is not pivotable, but by a guide 75 from a closed position, as in FIG Figure 4 is shown, can be converted into an open position.
- This guide 75 can be designed as a sliding guide, which positions the spray head 14 in a self-retaining manner in the closed position as well as in the raised position by a latching action relative to the housing 12.
- the storage container 41 can be gripped from the front and guided out. Subsequently, a new storage container 41 is first inserted into the receiving space 29 in the direction of the arrow 67, which is then transferred at right angles downward to the connecting piece 31 by a guide surface 77 on the receiving space 29 in an insertion movement. After a further pressure movement according to arrow 67 on the storage container 41, this snaps independently with the cartridge bottom 56 on the connector 31. A self-locking clip connection or the like is preferably provided. Then the spray head 14 is again moved towards the housing 12 and the receiving space 29 is closed.
- the end face which for example at Figure 1 the window 54 forms, free, that is, the viewing window 54 is not present. Rather, the storage container 41 has a viewing window in order to recognize the fill level. This end face of the storage container 41 is flush with the housing 12.
- the receiving space 29 is designed differently in that it has a section that is open towards the front and open against the direction of insertion, which merges into a semi-cylindrical wall section 78 that is closed on an upper side by the deflection surface 76.
- the bottom 32 of the receiving space 29 is provided opposite.
- the spray head 14 according to Figure 4 is also an alternative to that in Figure 1 educated.
- the hose line 36 is not directly connected to the nozzle 38. Rather, a pressure chamber 39 is formed in the spray head 14, which has a first opening 79 to which the hose line 36 is connected. This leads the air flow into the pressure chamber 39.
- the pressure chamber 39 is connected to the nozzle 38, as a result of which the stored or pent-up air is discharged in the pressure chamber 39 in the flow direction 65. Through this pressure chamber 39, pressure fluctuations in the hose line can be compensated for in the air flow generated.
- the nozzle 38 is preferably designed as a tube which projects at least partially into the pressure chamber 39.
- the fluid line 44 is also preferably designed as a tube. This can be provided in all embodiments.
- the hose line 36 is directly connected to the nozzle 38.
- the hose line 36 is either flexible or provided with an excess length, so that the spray head 14 can also move in and out relative to the housing 12 along the guide 75.
- the nozzle 44 and the nozzle 38 are advantageously arranged at an angle of less than 90 ° to one another. These are also separate from one another.
- a filter element is provided in the interior of the housing, directly associated with the air inlet openings 23, so that no dirt particles get into the interior of the housing in order to enable a long service life of the air pump 22.
- Figure 5 13 is a perspective view of an alternative embodiment of dispenser 11 Figure 1 shown.
- the Figure 6 shows the alternative output device 11 according to FIG Figure 5 with a partially not shown housing 12.
- Die Figure 7 shows a schematic sectional view of the output device 11 according to FIG Figure 5 to show the arrangement of the individual components to each other.
- the dispensing device 11 comprises a housing 12 which, for example, is formed in two parts, so that a first housing half can be removed from the second housing half.
- a housing section can be removed from the housing 12, which only allows access for inserting a storage container 11 and / or a closure 42 and / or a spray head 14, so that all further components remain closed by the housing 12.
- a motor 18 is provided in the housing 12 and is contacted with a control 17 at a lower end. Furthermore, the motor 18 connected to accumulators 19, as well as the controller 17.
- the drive motor 18 can be activated by an operating button 21 on the housing 12, whereby an air pump 22 is driven, which generates an air flow. This air flow is fed to the spray head 14 via the hose line 36. In particular, the nozzle 38 is thereby supplied with the air flow.
- a connection 81 is provided between the hose line 36 and the spray head 14. This connection 81 is preferably designed as a plug connection.
- a media-tight connection can be created by plugging or fitting a nozzle on the spray head 14 into or onto the hose line 36. This connection can be detachable, so that the spray head 14 can be designed to be interchangeable.
- the spray head 14 comprises the first nozzle 38, which according to arrow 65 has an exit direction for the air flow.
- the second nozzle 46 is oriented at an angle of preferably less than 90 °, in particular 89 ° to 80 °.
- the fluid stored in the reservoir 41 is dispensed via the second nozzle 46.
- an atomizing zone 49 is formed outside the spray head 14. Due to the air flow output from the nozzle 38, the fluid is conveyed out of the storage container 41, since a negative pressure is generated at the nozzle 46 by the air flow from the nozzle 38.
- This configuration of the spray head 14 has the advantage that when the dispensing device 11 is switched off, the fluid is withdrawn from the fluid line 44, in particular the nozzle 46, and returns to the storage container 41. This can prevent the nozzle 46 from drying out.
- the storage container 41 and the closure 42 are formed in one piece.
- the spray head 14 is releasably attached to it. It can be provided by a flange, snap, clip, plug or screw connection. Alternatively, it can be provided that the spray head 14 and the closure 42 are formed in one piece, so that the spray head 14 can be easily mounted on the storage container 41. Alternatively, you can the spray head 14 and the storage container 41 can also be formed in one piece, so that they form a sales unit which can be inserted completely into the housing 12.
- the storage container 41 can comprise an inlet air opening, so that pressure equalization in the storage container 41 is given automatically during the dispensing of the medium.
- the spray head 14 can have at least one nozzle 46 which, viewed in cross section, has a frustoconical body surrounding the nozzle opening.
- the nozzle opening can be provided higher than the truncated cone surface.
- This nozzle 46 lies with the mouth or the outlet opening preferably in the air flow emerging from the first nozzle 38 or is positioned adjacent to the air flow. This allows a better flow around the nozzle 46 due to the air flow in the discharge direction 65 from the nozzle 38. At the same time, clogging of the nozzle 46 can be prevented for at least a longer period.
- the nozzle outlet of the nozzle 38 can lie in a surface on the spray head 14 delimiting the atomizing zone 49 or can likewise have a frustoconical contour 47.
- a protective cap can be placed on the spray head 14.
- This protective cap can preferably have one or more closure elements, at least one closure element being provided for the nozzle 46 that emits the fluid. This can also prevent drying out. Such a protective cap also serves to protect against damage.
- an opening 79 can be provided on the housing 12 in order to read off the fill level of the storage container 41 in a simple manner.
- FIG 8 is shown schematically enlarged the spray head 14 and the atomizing zone 49, in which the positioning and assignment of the nozzle 38 and the nozzle 46 is shown.
- the nozzle opening of the nozzle 46 protrudes at least slightly into the air flow emerging from the nozzle 38 in order to atomize the medium supplied through the nozzle 46.
- the nozzle opening of the nozzle 46 is opposite one of the Atomizing zone 49 delimiting inclined surface. This inclined surface is provided so that it slopes away from the nozzle 38, so that the surface opens towards the atomizing zone 49.
- the nozzle 38 can protrude from an end face of the spray head 14, as shown in FIG Figure 8 is shown, or also be positioned flush with the end face of this inclined surface.

Description
Die Erfindung betrifft eine Ausgabevorrichtung zum Versprühen eines sprühfähigen Fluides, welches als Handgerät ausgebildet ist.The invention relates to an output device for spraying a sprayable fluid, which is designed as a hand-held device.
Zum Auftragen von Make-up ist ein sogenanntes Airbrush-System bekannt. Solche Geräte werden von professionellen Visagisten eingesetzt. Diese weisen einen Kompressor sowie mehrere Schlauchleitungen auf, welche von einzelnen Speichern verschiedener Make-ups das jeweilige Make-up entnehmen und über eine gemeinsame Sprühdüse austragen. Sie werden nach dem jeweiligen Gebrauch gereinigt, so dass diese für den nachfolgenden Einsatz wieder bereitgestellt sind. Solche Airbrush-Systeme eignen sich jedoch nicht für die Mitnahme in einer Handtasche, so dass beispielsweise ein schnelles Auftragen oder Auffrischen des Make-ups ermöglicht ist.A so-called airbrush system is known for applying make-up. Such devices are used by professional make-up artists. These have a compressor and several hose lines, which remove the respective make-up from individual stores of different make-ups and discharge them via a common spray nozzle. They are cleaned after each use so that they are available for subsequent use. However, such airbrush systems are not suitable for being carried in a handbag, so that, for example, the make-up can be applied or refreshed quickly.
Aus der
Der Erfindung liegt die Aufgabe zugrunde, eine Ausgabevorrichtung zum Versprühen eines sprühfähigen Fluides zu schaffen, welche als Handgerät ausgebildet ist und eine verbesserte Funktionalität aufweist.The invention has for its object to provide an output device for spraying a sprayable fluid, which is designed as a handheld device and has an improved functionality.
Diese Aufgabe wird durch eine Ausgabevorrichtung gelöst, bei welcher der Sprühkopf eine erste mit einer Fluidleitung in Verbindung stehenden Düse und getrennt dazu eine zweite Düse im Sprühkopf aufweist, und die erste Düse mit der Luftströmung aus einer mit der ersten Düse in Verbindung stehenden Schlauchleitung versorgt wird und die Düsenöffnung der ersten Düse zumindest geringfügig in die aus der zweiten Düse austretende Luftströmung ragt. Dadurch wird ermöglicht, dass das durch die erste Düse zugeführte Medium zerstäubt wird.This object is achieved by an output device in which the spray head has a first nozzle connected to a fluid line and separately a second nozzle in the spray head, and the first nozzle is supplied with the air flow from a hose line connected to the first nozzle and the nozzle opening of the first Nozzle protrudes at least slightly into the air flow emerging from the second nozzle. This enables the medium supplied through the first nozzle to be atomized.
Eine bevorzugte Ausführungsform der Ausgabevorrichtung sieht vor, dass die Austragrichtung der ersten Düse zum Austragen der Luftströmung und die Austragrichtung der zweiten Düse, über welche das Fluid ausgegeben wird, in einem Winkel von 90° zueinander ausgerichtet sind oder in einem Winkel von weniger als 90° zueinander ausgerichtet sind. Durch eine solche Ausrichtung der beiden Düsen zueinander, beziehungsweise der beiden Düsenkanäle, kann eine besonders bevorzugte Zerstäubung erfolgen. Gleichzeitig kann dadurch auch erzielt werden, dass durch die aus der ersten Düse austretende Luftströmung das Fluid nach dem Venturiprinzip aus der zweiten Düse herausgefördert wird.A preferred embodiment of the dispensing device provides that the discharge direction of the first nozzle for discharging the air flow and the discharge direction of the second nozzle, via which the fluid is discharged, are oriented at an angle of 90 ° to one another or at an angle of less than 90 ° are aligned with each other. Such an alignment of the two nozzles relative to one another, or of the two nozzle channels, enables particularly preferred atomization. At the same time it can also be achieved that the fluid is conveyed out of the second nozzle according to the Venturi principle by the air flow emerging from the first nozzle.
Eine bevorzugte Ausführungsform der Ausgabevorrichtung sieht vor, dass der Sprühkopf an einem lösbaren Verschluss des Vorratsbehälters anordenbar ist. Dabei kann der Sprühkopf aufgeflanscht, aufgeschraubt, aufgeklipst oder aufgeklemmt befestigbar sein. Alternativ kann vorgesehen sein, dass der Sprühkopf einstückig an dem Verschluss des Vorratsbehälters integriert ist. Des Weiteren kann vorgesehen sein, dass der Sprühkopf, der Verschluss und der Vorratsbehälter einstückig ausgebildet sind, oder dass der Sprühkopf an dem Vorratsbehälter einstückig ausgebildet ist und gleichzeitig den Verschluss bildet. Diese Varianten ermöglichen, dass bei einem Farbwechsel der aufzutragenden Substanz, dass der Sprühkopf und der Vorratsbehälter, die eine Einheit bilden, gleichzeitig gewechselt werden. Dadurch kann eine Durchmischung von Substanzen bei einem verbleibenden Fluid in der Fluidleitung am Sprühkopf oder der Düse verhindert sein. Durch die mögliche Austauschbarkeit des Sprühkopfes kann bei einem noch nicht verbrauchten Vorratsbehälter bei einer möglichen Beeinträchtigung des Sprühkopfes das Fluid vollständig verbraucht werden.A preferred embodiment of the dispensing device provides that the spray head can be arranged on a detachable closure of the storage container. The spray head can be flange-mounted, screwed on, clipped on or clamped on. Alternatively, it can be provided that the spray head is integrated in one piece on the closure of the storage container. Furthermore, it can be provided that the spray head, the closure and the storage container are formed in one piece, or that the spray head is formed in one piece on the storage container and simultaneously forms the closure. These variants enable the spray head and the storage container, which form a unit, to be changed at the same time when the color of the substance to be applied is changed. Mixing of substances with a remaining fluid in the fluid line on the spray head or nozzle can thereby be prevented. Due to the possible interchangeability of the spray head, the fluid can be completely used up in a storage container that has not yet been used, if the spray head is impaired.
Zur einfachen Austauschbarkeit des Sprühkopfes ist bevorzugt vorgesehen, dass entgegengesetzt zur Austragsrichtung der ersten Düse am Sprühkopf ein Anschluss vorgesehen ist, der mit der Schlauchleitung mediendicht verbindbar ist. Bevorzugt ist eine einfache Steckverbindung vorgesehen, so dass nach dem Einsetzen des Vorratsbehälters in das Gehäuse bei einem damit befestigten Sprühkopf durch ein einfaches Aufschieben oder Aufstecken der mediendichte Anschluss geschaffen ist. Alternativ kann auch bei einem ausschließlichen Wechsel des Sprühkopfes eine solche Aufsteckschnittstelle ein einfaches Anbinden ermöglichen.For easy interchangeability of the spray head, it is preferably provided that, opposite to the discharge direction of the first nozzle, a connection is provided on the spray head that connects to the hose line can be connected in a media-tight manner. A simple plug-in connection is preferably provided, so that after the storage container has been inserted into the housing in the case of a spray head fastened therewith, the media-tight connection is created simply by pushing on or plugging on. Alternatively, such a plug-on interface can also be easily connected if the spray head is replaced exclusively.
Eine weitere vorteilhafte Ausführungsform der Ausgabevorrichtung sieht vor, dass der Sprühkopf, der Verschluss und/oder der Vorratsbehälter austauschbar zum Gehäuse vorgesehen sind und vorzugsweise durch eine Rast-, Steck-, Klemm-, Klips- und/oder Schraubverbindung lösbar zueinander und/oder zum Gehäuse befestigbar sind. Dies ermöglicht eine einfache Austauschbarkeit der einzelnen Komponenten oder einer Einheit, die vorzugsweise aus einem Vorratsbehälter und einem daran angeordneten Sprühkopf besteht.A further advantageous embodiment of the dispensing device provides that the spray head, the closure and / or the storage container are provided interchangeably with the housing and preferably releasably to one another and / or to by a snap-in, plug-in, clamp, clip and / or screw connection Housing can be attached. This enables the individual components or a unit to be easily exchanged, which preferably consists of a storage container and a spray head arranged thereon.
Eine weitere bevorzugte Ausführungsform der Ausgabevorrichtung sieht vor, dass zur Ausgabe des Fluides über die mit dem Vorratsbehälter in Verbindung stehende Düse ein Luftstrom aus der weiteren Düse im Sprühkopf mit einem Volumenstrom von 1 bis 10 Liter/Minute (l/min), insbesondere von 1 bis 5 Liter/Minute (l/min), austritt. Dadurch kann eine hinreichende Zerstäubung einerseits und eine hinreichend große Sprühfläche mit einer gleichmäßigen Konzentration des Fluids erzielt werden.A further preferred embodiment of the dispensing device provides that for dispensing the fluid via the nozzle connected to the storage container, an air flow from the further nozzle in the spray head with a volume flow of 1 to 10 liters / minute (l / min), in particular of 1 up to 5 liters / minute (l / min). Adequate atomization on the one hand and a sufficiently large spray area with a uniform concentration of the fluid can thereby be achieved.
Vorteilhafterweise werden in dem Vorratsbehälter Fluide bereitgestellt, welche aus natürlichen, insbesondere pflanzlichen Substanzen auf einer Wasserbasis bestehen. Diese eignen sich im besonderen Maße zur Ausgabe einer solchen Ausgabevorrichtung.Advantageously, fluids are provided in the reservoir, which consist of natural, in particular vegetable substances on a water basis. These are particularly suitable for the output of such an output device.

In dem Gehäuse 12 ist ein elektrischer Antriebsmotor 18 vorgesehen. Dieser wird beispielsweise mittels eines Akkumulators 19 versorgt. Dieser kann auswechselbar in dem Gehäuse 12 vorgesehen sein. Alternativ kann eine kabellose als auch eine kabelgebundene Aufladung des Akkumulators 19 vorgesehen sein. Mittels eines Bedienknopfes 21 wird die Ausgabevorrichtung 11 ein- und ausgeschalten. Der Antriebsmotor 18 treibt eine Luftpumpe 22 an. Diese wird durch Einlassöffnungen 23 in der Gehäusewand des Gehäuses 12 mit Luft versorgt. Dabei können eine oder mehrere Lufteinlassöffnungen 23 in der Gehäusewand vorgesehen sein. Die Luftpumpe 22 umfasst einen Auslassstutzen 25, durch welchen eine durch die Luftpumpe 22 erzeugte Luftströmung ausgegeben wird. An diesen Auslassstutzen 25 ist beispielsweise ein Abzweig 26 anschließbar, durch welchen die erzeugte Luftströmung aufgeteilt wird. Diese kann in eine Druckleitung 28 übergeführt werden, welche in einen Aufnahmeraum 29 im Gehäuse 12 führt. Bevorzugt ist die Druckleitung 28 mittels eines Anschlussstücks 31 am Boden 32 des Aufnahmeraumes 29 befestigt und weist eine Einlassöffnung 34 auf, die in den Aufnahmeraum 29 mündet.An
Die durch die Luftpumpe 22 erzeugte Luftströmung kann des Weiteren mittels des Abzweigs 26 in eine Schlauchleitung 36 übergeführt werden. Diese Schlauchleitung 36 führt in den Sprühkopf 14 und endet in einer Düse 38 zur Ausgabe der Luftströmung.The air flow generated by the
In den Aufnahmeraum 29 des Gehäuses 12 ist ein Vorratsbehälter 41 einsetzbar. Dieser Vorratsbehälter 41 nimmt das sprühfähige Fluid, insbesondere Make-up, auf. Der Vorratsbehälter 41 weist ausgabeseitig einen Verschluss 42 auf, der vorzugsweise als selbstheilender Verschluss ausgebildet ist. An diesen Verschluss 42 ist eine Fluidleitung 44 anschließbar. Vorzugsweise umfasst die Fluidleitung 44 zum Verschluss 42 weisend eine Nadel 45, so dass nach dem Einsetzen des Vorratsbehälters 41 in den Aufnahmeraum 29 und einer anschließenden Schließbewegung des Sprühkopfes 14 zum Gehäuse 12 die Nadel 45 der Fluidleitung 44 in den Verschluss 42 eingreift und die Ausgabe des sprühfähigen Fluides ermöglicht.A
Der Nadel 45 gegenüberliegend weist die Fluidleitung 44 eine Düse 46 auf. Diese Düse 46 zur Ausgabe des Fluides ist getrennt zur Düse 38 zur Ausgabe der Luftströmung zum Sprühkopf 14 vorgesehen. Beispielsweise sind die Düsen 38, 46 als Röhrchen ausgebildet. Das Zerstäuben des Fluides findet in einer Zerstäuberzone 49 des Sprühkopfes 14 statt, welcher beispielsweise trichterförmig, glockenförmig oder dergleichen ausgebildet ist.The
Zur Ansteuerung der über die Düse 38 auszugebenden Luftströmung ist bevorzugt ein Luftdruckregler 51 vorgesehen, der über ein Bedienelement oder Stellelement 52, insbesondere ein Stellrad, einstellbar ist. Vorteilhafterweise ist auch in der Druckleitung 28 ein solcher Luftregler 51 mit einem Stellelement 52 vorgesehen.To control the air flow to be output via the
Der Aufnahmeraum 29 ist Teil einer Gehäusewand oder grenzt an eine Gehäusewand an, wobei das Gehäuse 12 im Bereich des Vorratsbehälters 41 vorteilhafterweise ein Sichtfenster 54 umfasst, um den Füllstand im Vorratsbehälter 41 erkennen zu können.The receiving
Der Vorratsbehälter 41 gemäß
Zur Ausgabe des sprühfähigen Fluides wird der Bedienknopf 21 betätigt. Der Antriebsmotor 18 wird durch den Akkumulator 19 bestromt. Der Antriebsmotor 18 treibt die Luftpumpe 22 an, wodurch eine Luftströmung erzeugt wird. Der Massenstrom der Luftströmung wird über die Druckleitung 28 in den Vorratsbehälter 41 geführt, wodurch zwischen dem Kartuschenboden 56 und dem verschiebbaren Boden 49 ein Überdruck aufgebaut wird.The
Der verschiebbare Boden 59 wird in Richtung des Verschlusses 42 verschoben. Dadurch wird das Fluid über die Fluidleitung 44 zur Düse 46 geführt und ausgegeben. Gleichzeitig wird der zweite Massenstrom der Luftströmung über die Schlauchleitung 36 zur Düse 38 geführt und ausgegeben. Dabei findet eine Zerstäubung des Fluides in der Zerstäuberzone 49 statt, wodurch ein Versprühen des versprühfähigen Fluides in Austragsrichtung gemäß Pfeil 65 erfolgt. Im Falle eines entstehenden Vakuums, in dem das Fluid über die Fluidleitung 44 durch die Luftströmung aus der Düse 46 herausgezogen wird, ist der Fluidraum druckmäßig wieder ausgeglichen.The displaceable bottom 59 is displaced in the direction of the
Sobald der Bedienknopf 21 gelöst oder erneut betätigt wird, schaltet der Antriebsmotor 18 ab. Dabei wird der Druck zwischen dem Kartuschenboden 56 und dem verschiebbaren Boden 59 verringert. Der verschiebbare Boden 59 geht wieder in seine Ausgangsposition zurück, wodurch in dem Vorratsbehälter 41 ein geringer Unterdruck erzeugt wird, durch welchen das Fluid in der Fluidleitung 44 wieder zurück in den Innenraum 62 des Vorratsbehälters 41 gesaugt wird.As soon as the
Die Fluidleitung 44 ist im Verhältnis zur Schlauchleitung 36 um ein Vielfaches kürzer ausgebildet. Dadurch wird die geringe, in der Fluidleitung 44 sich ansammelnde Menge nach dem Abschalten des Antriebsmotors 18 wieder in den Vorratsbehälter 41 zurückgeführt, um ein Austrocknen der Fluidleitung zu vermeiden.The
Zum Auswechseln des Vorratsbehälters 41 wird der Sprühkopf 14 geöffnet, wie dies gemäß dem Pfeil 67 in

Gegenüberliegend ist der Boden 32 des Aufnahmeraumes 29 vorgesehen. Dadurch kann der Vorratsbehälter 41 einfach von vorne eingesetzt und mit dem Anschlussstück 31 verrastend verbunden werden.In this embodiment, the receiving

Bevorzugt ist die Düse 38 als ein Röhrchen ausgebildet, welches zumindest teilweise in den Druckraum 39 ragt. Auch die Fluidleitung 44 ist bevorzugt als ein Röhrchen ausgebildet. Dies kann bei allen Ausführungsformen vorgesehen sein.The
Auch bei dieser Ausführungsform gemäß
Die Schlauchleitung 36 ist entweder flexibel oder mit einer Überlänge vorgesehen, so dass der Sprühkopf 14 gegenüber dem Gehäuse 12 entlang der Führung 75 auch eine Ein- und Ausfahrbewegung durchführen kann.The
Die Düse 44 und die Düse 38 sind vorteilhafterweise in einem Winkel von weniger als 90° zueinander angeordnet. Diese sind auch getrennt voneinander.The
Bei allen Ausführungsformen kann vorteilhafterweise vorgesehen sein, dass im Gehäuseinneren unmittelbar den Lufteinlassöffnungen 23 zugeordnet ein Filterelement vorgesehen sind, so dass keine Schmutzpartikel ins Gehäuseinnere gelangen, um eine lange Lebensdauer der Luftpumpe 22 zu ermöglichen.In all embodiments, it can advantageously be provided that a filter element is provided in the interior of the housing, directly associated with the

Die Ausgabevorrichtung 11 umfasst ein Gehäuse 12, welches beispielhaft zweiteilig ausgebildet ist, so dass eine erste Gehäusehälfte von der zweiten Gehäusehälfte abnehmbar ist. Dadurch kann vereinfacht ein Austausch zumindest des Vorratsbehälters 41 erfolgen. Alternativ kann vorgesehen sein, dass ein Gehäuseabschnitt von dem Gehäuse 12 abnehmbar ist, der lediglich einen Zugang zum Einsetzen eines Vorratsbehälters 11 und/oder eines Verschlusses 42 und/oder eines Sprühkopfes 14 ermöglicht, so dass alle weiteren Bauteile durch das Gehäuse 12 verschlossen bleiben.The dispensing
In dem Gehäuse 12 ist ein Motor 18 vorgesehen, der an einem unteren Ende mit einer Steuerung 17 kontaktiert ist. Des Weiteren ist der Motor 18 mit Akkumulatoren 19 verbunden, ebenso wie die Steuerung 17. Durch einen Bedienknopf 21 am Gehäuse 12 kann der Antriebsmotor 18 aktiviert werden, wodurch eine Luftpumpe 22 angetrieben wird, welche eine Luftströmung erzeugt. Diese Luftströmung wird über die Schlauchleitung 36 dem Sprühkopf 14 zugeführt. Insbesondere wird dadurch die Düse 38 mit der Luftströmung versorgt. Zwischen der Schlauchleitung 36 und dem Sprühkopf 14 ist ein Anschluss 81 vorgesehen. Dieser Anschluss 81 ist bevorzugt als Steckverbindung ausgebildet. Durch ein Aufstecken oder Aufsetzen eines Stutzens am Sprühkopf 14 in oder auf die Schlauchleitung 36, kann eine mediendichte Verbindung geschaffen werden. Diese Verbindung kann lösbar sein, so dass der Sprühkopf 14 austauschbar ausgebildet sein kann.A
Der Sprühkopf 14 umfasst die erste Düse 38, welche gemäß Pfeil 65 eine Austrittsrichtung für die Luftströmung aufweist. In einem Winkel bevorzugt von weniger als 90°, insbesondere 89° bis 80°, ist die zweite Düse 46 ausgerichtet. Über die zweite Düse 46 wird das in dem Vorratsbehälter 41 bevorratete Fluid ausgegeben. Durch diese Anordnung und Ausrichtung der Düsen 38, 46 zueinander wird außerhalb des Sprühkopfes 14 eine Zerstäuberzone 49 ausgebildet. Durch die aus der Düse 38 ausgegebene Luftströmung wird das Fluid aus dem Vorratsbehälter 41 herausgefördert, da an der Düse 46 durch die Luftströmung der Düse 38 ein Unterdruck erzeugt wird. Diese Ausgestaltung des Sprühkopfes 14 weist den Vorteil auf, dass beim Abschalten der Ausgabevorrichtung 11 das Fluid aus der Fluidleitung 44, insbesondere der Düse 46, zurückgezogen wird und in den Vorratsbehälter 41 zurückkehrt. Dadurch kann ein Austrocknen der Düse 46 verhindert sein.The

Der Sprühkopf 14 kann gemäß einer alternativen Ausführungsform zumindest eine Düse 46 aufweisen, die im Querschnitt gesehen einen die Düsenöffnung umgebenden kegelstumpfförmigen Körper aufweist. Die Düsenöffnung kann gegenüber der Kegelstumpffläche erhöht vorgesehen sein. Diese Düse 46 liegt mit der Mündung oder der Austrittsöffnung bevorzugt in der aus der ersten Düse 38 austretenden Luftströmung oder ist an die Luftströmung angrenzend positioniert. Dadurch kann eine bessere Umströmung der Düse 46 durch die Luftströmung in Austragsrichtung 65 aus der Düse 38 erfolgen. Gleichzeitig kann ein Zusetzen der Düse 46 über zumindest einen längeren Zeitraum verhindert sein. Der Düsenaustritt der Düse 38 kann in einer die Zerstäuberzone 49 begrenzenden Fläche am Sprühkopf 14 liegen oder ebenfalls eine Kegelstumpfförmige Kontur 47 aufweisen.According to an alternative embodiment, the

Bevorzugt kann diese Schutzkappe ein oder mehrere Verschlusselemente aufweisen, wobei zumindest ein Verschlusselement für die das Fluid ausgebende Düse 46 vorgesehen ist. Dadurch kann ergänzend ein Austrocknen verhindert sein. Zudem dient eine solche Schutzkappe zum Schutz vor Beschädigungen.It is preferred and not shown in detail that a protective cap can be placed on the
