Definitions

  • the invention relates to a liquid dispenser with a discharge head.
  • Generic discharge heads serve the purpose of delivering liquids in the form of a spray. These may be, in particular, cosmetic liquids such as perfumes and the like, or pharmaceutical liquids such as, for example, insect bites or foods such as olive oil.
  • document WO2014 / 138421 A1 discloses a liquid dispenser of the prior art.
  • the object of the invention is to provide a liquid dispenser with a discharge head available that allow either the discharge in atomized form or in the form of drops or a jet / stream.
  • the discharge head is for attachment to a base unit of the liquid dispenser provided, which comprises a liquid storage.
  • the discharge head has a housing, which is preferably displaceable relative to the base unit for the purpose of actuating the liquid dispenser. It has a liquid inlet through which liquid to be discharged can pass from the liquid reservoir into the discharge head, and has a discharge opening through which the liquid can be discharged into a surrounding atmosphere.
  • a vortex chamber is provided with at least one eccentrically opening inlet channel, so that inflowing liquid is provided with a twist, which causes the formation of a spray jet on exit from the discharge opening.
  • the vortex chamber is switchable by changing the geometry of walls of the vortex chamber and / or the at least one inlet channel at least between a first and a second configuration. There is a handle for manually switching between the configurations. In a first configuration, the liquid is delivered as a spray. In a second configuration, the liquid is discharged as stream / jet. Designs are also possible in which there are further intermediate configurations.
  • the discharge head according to the invention which is used for the forwarding of the liquid to be discharged from the inlet channel to the discharge, according to the invention has a vortex chamber which can be activated and deactivated manually by the user of the liquid dispenser. If the vortex chamber is activated due to the geometry and relative arrangement of its walls, the vortex chamber itself or an inlet channel which enters the vortex chamber eccentrically and preferably tangentially has a geometry suitable for causing a vortex, by means of which when the liquid exits through the Outlet a spray cone is generated.
  • the user can switch to the second configuration, in which not a spray, but liquid is discharged in the form of a continuous liquid flow / liquid jet or in drop form. In this second configuration, the walls of the swirl chamber and / or the shape of the inlet channel are changed so that no more swirl is generated in the liquid or this is so small that it is insufficient to form a spray.
  • the user of the liquid dispenser can set case by case, whether he wants to spray a product or would like to spend in the form of a liquid flow or drops. This is for example in application fields such as the delivery of perfume or olive oil a sensible choice.
  • the change in the geometry of the swirl chamber and / or the inlet channel is preferably effected by the fact that the swirl chamber or the inlet channel is limited by two swirl chamber components which are mutually movable.
  • Possibilities for influencing the effectiveness of the vortex chamber are, in particular, that the flow resistance in the vortex chamber is reduced by the relative movement of the vortex chamber components in order to prevent the formation of the vortex, and / or that the eccentricity of the inflow of the liquid is changed, since so the twist can be influenced.
  • the vortex chamber components are translationally movable against each other, so slide along a guide. Due to structural simplicity is particularly preferred when the vortex chamber components are mutually linearly movable.
  • a first of the vortex chamber component in which preferably an opening forming the discharge opening is provided on an inner side with a recess whose walls define the vortex chamber, and / or it is provided with a groove whose walls define the inlet channel in the vortex chamber
  • the second vortex chamber component has an end-side abutment surface, which bears against the first vortex chamber component in the first configuration, so that the abutment surface together with the depression defines the vortex chamber and / or the abutment surface forms the inlet channel together with the walls of the groove.
  • both vortex chamber components have mutually facing contact surfaces, which preferably lead to a planar arrangement of the vortex chamber components together. At least one of these contact surfaces has depressions which form the vortex chamber itself and / or the at least one inlet channel which flows eccentrically into the vortex chamber.
  • a design is also conceivable in which the depression forming the vortex chamber is provided on one of the vortex chamber components, and the depression forming the inlet channel is provided on the other vortex chamber component.
  • the two contact surfaces are removed from each other, a gap is created between them, through which liquid can flow directly and centrically into the vortex chamber, with the greatest possible circumvention of the inlet channel, whereby the flow resistance associated therewith is usually reduced.
  • the liquid flows in this second configuration, preferably through the circumferential annular gap in the vortex chamber.
  • either the vortex chamber component comprising the discharge opening or the vortex chamber component not comprising the discharge opening can be that which is displaced relative to the housing of the discharge head.
  • the vortex chamber component provided with the discharge opening is stationary relative to the housing or is formed by the housing itself, while the displaceable vortex chamber component is an inner component of the discharge head whose position is preferably not visible from outside.
  • the dispensing head as a whole can be the handle for manually switching between configurations. This is given in a design in which the discharge head is mounted relative to a base movable relative thereto and the relative position of the vortex chamber components to each other by a relative displacement of the discharge head and the base can be effected.
  • a displaceable relative to the housing of the discharge head button for manual switching of the configuration is provided on the discharge head itself, which directly or indirectly affects the relative position of the vortex chamber components.
  • An immediate influence is given when the button is stationary to a vortex chamber component, so that the displacement of the button alike also causes a displacement of one of the vortex chamber components relative to the housing.
  • a transmission is provided, via which the movement of the button relative to the housing with the movement of the vortex chamber component is coupled to the housing.
  • a transmission can be formed, for example, by two mutually sliding inclined planes on the side of the button and on the sides of the vortex chamber component.
  • a return spring which acts between the swirl chamber components, so that the swirl chamber components are always subjected to force in the direction of an end position and are displaced by application of force of the button against the force of the return spring.
  • the return spring causes only one of the configurations, that is, only one of the relative positions of the swirl chamber components to one another, is stable. Only as long as the button is powered by the user, the vortex chamber components therefore remain in the other, unstable configuration.
  • the button for switching the configurations is mounted in the region of an actuating surface of the discharge head, on which a force application can take place in order to initiate a liquid discharge. With such a configuration, the user can simultaneously select the configuration for the discharge and cause the discharge by the application of force to said actuating surface or the button adjacent thereto.
  • the invention relates to a liquid dispenser with a liquid storage for receiving liquid before discharge and with a discharge head of the type described above.
  • the liquid dispenser may have a pumping device which can be actuated by a translational relative movement of the discharge head relative to the base unit and promotes liquid from the liquid storage in the discharge head.
  • a liquid dispenser has a liquid storage in which the liquid is depressurized.
  • a pumping chamber which is preferably provided on the input side and output side with pressure relief valves, volumetrically reduced, so that the liquid is conveyed into the discharge head and in the direction of the swirl chamber and the discharge opening.
  • the liquid storage can be designed as an accumulator and the liquid dispenser have a valve device which can be actuated by a translational relative movement of the discharge head relative to the base unit and promotes liquid from the liquid storage in the discharge head.
  • a depression of the discharge head relative to the liquid storage only leads to an opening of an exhaust valve.
  • the pressurization of the liquid is already given as an accumulator due to the design of the liquid reservoir, so that when the outlet valve is open, the liquid flows in the direction of the vortex chamber and the discharge opening.
  • the discharge head is rotatable about an axis of rotation relative to the base unit and a transmission is provided, by means of which a rotary movement of the discharge head causes a relative displacement of the vortex chamber components.
  • the advantage with such a design is, in particular, that the movement for initiating a discharge, usually the depression of the discharge head, is separated from the movement for switching the configurations by changing the relative displacement of the vortex chamber components. The user can thus first change the configuration of the discharge head in a very convenient and very dose possible manner and then trigger a discharge according to the selected configuration by depressing the discharge head.
  • the transmission preferably includes a guide member with angular spacing from the rotation axis provided on a swirl chamber member of the discharge head or on the base unit, and a guide slider which is engaged with the guide member and provided on the base unit or on one of the swirl chamber members.
  • the angle-dependent spacing is preferably generated by a spiral section shape.
  • the guide slide slides along the guide element, it also changes its distance from the axis of rotation, thus causing a radial displacement.
  • the guide element could also undergo a radial displacement. This radial displacement can be used to radially displace one of the vortex chamber component.
  • Fig. 1 shows a liquid dispenser 10 according to the invention in an overall view.
  • This liquid dispenser 10 has a liquid reservoir 20 and a discharge device 30, which is screwed onto a neck 22 of the liquid reservoir 20.
  • the discharge device 30 in turn has a fixed to the liquid storage base 40 and provided on the base 40 and depressible in an operating direction 2A discharge head 50.
  • On the base 40 is further provided an outlet control 42 in the form of a valve device or a pumping device, which at its upper End has an outlet 44.
  • this outlet port 44 is depressed in the direction 2A, depending on the configuration, the outlet control 42 designed as a valve device is opened so that pressurized fluid can flow into the discharge head 50, or a pumping operation is effected on the outlet control 42 designed as a pumping device, so that Liquid is conveyed from a pumping chamber, not shown in the discharge head and the pumping chamber is refilled from the liquid reservoir 20 during the later return stroke.
  • the discharge head 50 has a multipart housing 52, which has a discharge nozzle 56 on a separate nozzle component 54. Upstream of the discharge opening 56 is a swirl chamber 58, into which tangentially oriented inlet channels 60 open.
  • FIG. 5A A second possible configuration is in Fig. 5A as well as in the mentioned FIGS. 2 and 3 ,
  • the punch member 70 is displaced to the right in the radial direction from the first configuration of the swirler chamber main constituent member 54.
  • This causes the vortex chamber 58 itself and the inlet channel 60, which flows in tangentially into it, to be opened, as it were.
  • the inlet channel 60 almost completely loses its function, since liquid can now flow into the vortex chamber via an annular gap 64. It is therefore no longer in the vortex chamber 58 to the formation of a liquid swirl to a relevant extent. Instead, the liquid is discharged through the discharge port 56 as an atomized jet.
  • FIGS. 4A and 4B on the one hand and the Figs. 5A and 5B on the other hand illustrate again the change in the relative position of the punch member 70 relative to the swirl chamber member 54. This is in particular the change between the configurations.
  • a planar web extending into the discharge head 50, which forms a guide element 46 is provided on the base 40.
  • this guide member 46 does not surround the central axis 4 at a constant distance, but has a more spiral-shaped portion.
  • This guide member 46 cooperates with a guide slider 74 provided at the rear end 76 of the punch member 70.
  • This radial displacement simultaneously causes the desired radial displacement of the punch member 70 and its end face 72, so that said configurations can be changed by the rotational movement.
  • FIGS. 6A and 6B show a second variant whose operation with respect to the activation and deactivation of the spray jet generation by opening and closing the swirl chamber 58 matches the above-described embodiment. Notwithstanding the above-described embodiment is provided here, however, that the punch member 70 via a spring 88 permanently in the direction of the configuration of Fig. 6A , ie the spray configuration, is pressed. In order to deflect the stamp component 70, a button 86 is provided which enables a deflection of the stamp component 70 against the force of the spring 88 via a gear 80 in the form of two abutting surface portions 70A, 86A.
  • a handle 84 is provided on the stamp member 70 at its rear end, which allows by pulling out and pushing in the two configurations for generating a spray jet or an atomized liquid jet.
