Definitions

  • the invention relates to a pump device for remplisstechnikszerstäubervorraumen, which has at least one fluid input line, at least one pumping chamber and at least one fluid outlet line, and at least one input valve between at least one fluid inlet line and at least one pumping chamber and at least one output valve between at least one pumping chamber and at least one fluid outlet line , Furthermore, the invention relates to a liquid atomizer and a scenting device. Moreover, the invention relates to a method for operating a pumping device.
  • pumped atomizers For example, by a user through a mechanical operation pumped a small amount of liquid to a corresponding pump, thereby pressurized, and ejected in the direction of a nozzle head. At the nozzle head, the pressure of the liquid causes a sputtering of the same into many small to smallest drops. The liquid is thus broken up into a mist of minute liquid droplets, often referred to as sputtering.
  • Such pump sprayers since they are often disposable, must be relatively simple and inexpensive to build. Nevertheless, the pump sprayers should work reliably. If possible, the pump sprayers should also meet relatively high hygienic requirements. Furthermore, such pump sprayers should be as universally usable.
  • the object of the invention is thus to propose a pumping device for remplisstechnikszerstäubervorraumen, which is as universally applicable.
  • the object of the invention is to propose a liquid atomizer which is as universally usable as possible and a scenting device which is as universally usable as possible.
  • the invention consists in proposing an improved method for operating a pumping device.
  • a pump device for remplisstechnikszerstäubervoriquesen which has at least one fluid input line, at least one pumping chamber and at least one fluid outlet line, and between at least one fluid input line and at least one pumping chamber at least one input valve and between at least one pumping chamber and at least one fluid outlet line at least one output valve is arranged to form such that at least one fluid branch line is provided.
  • the fluid branch line With the aid of the fluid branch line, it is possible to divert a portion of the fluid being pumped or the fluid still to be pumped instead of delivering the corresponding fluid to the fluid exit line and, in turn, to a "consumer".
  • the branched off fluid can be used, for example, for other purposes or, in particular, can be returned to a suction region where it can again be available to the pump device.
  • a portion of the fluid is "effectively", ie spent on the actual "consumer”.
  • This in turn kahn the discharged fluid amount can be reduced in a particularly simple manner.
  • Due to the proposed modification however, these may "pump" or discharge significantly smaller amounts of liquid under certain circumstances. Since the proposed modification can be carried out very inexpensively, thereby a very cost-effective pumping device can be realized which, however, can handle very small to very small amounts of liquid.
  • the ratio of effectively discharged fluid and branched fluid can be ensured by appropriate measures, such as in particular by a corresponding dimensioning of the fluid resistance of the "consumer” and the fluid resistance of the fluid branch line.
  • a fluid is to be understood as meaning, in particular, liquids, gases, liquid-gas mixtures and supercritical fluids.
  • the fluids may also contain, to some extent, solids in the form of suspended solids (eg, smoke, suspensions).
  • At least one valve, in particular an input valve and / or an outlet valve of the pump device is designed as a self-closing valve, in particular designed as a force-loaded valves.
  • a self-closing valve in particular designed as a force-loaded valves.
  • ball valves can fall out of their closed position in the event of an "overhead position" of the pump device, and thus can no longer cause a fluid closure.
  • the self-closing function can be realized in a simple way by acting on the closure body of the valve with a force which is effected or mediated in particular by means independent of the closure body.
  • the application of force can be selected such that it is slightly larger than a gravitational force and / or acceleration force acting on the closure body (eg caused by impacts, centrifugal forces, deceleration forces, etc.).
  • At least one self-closing valve is spring loaded and / or magnetic.
  • a force application of the closure body of the self-closing valve for example, by means of a spring (in particular by means of a coil spring) particularly simple and inexpensive, but still very reliable realized.
  • the valve closure body is designed as a permanent magnet and the magnetic fields generated by the permanent magnet interact with other assemblies of the valve, which may be made in particular of a ferromagnetic material.
  • the permanent magnet is designed in conjunction with other assemblies of self-closing valve, and the magnetic fields generated by this with the valve closure body, which is made for example of a ferromagnetic material, interact.
  • the fluid channel can be kept free of fluid flow obstructing internals substantially.
  • At least one fluid branch line is in fluid communication with at least one fluid outlet line and / or at least one pumping chamber.
  • the fluid branch line is in fluid communication with at least one fluid outlet line.
  • the fluid branching line in the form of a simple opening (for example by means of a bore, an orifice element, etc.).
  • At least one fluid branch line is provided with at least one branch valve.
  • Such a design is particularly useful when the fluid branch line is in fluid communication with at least one pumping chamber.
  • tests have shown that the provision of a branch valve can prevent problems with the suction process (filling the pumping chamber) particularly effective. As a result, a puncture impairment of the pumping device can be prevented particularly effectively in a simple manner.
  • branch valves even if the fluid branch line communicates with other elements, such as a fluid exit line.
  • At least one valve in particular at least one branch valve, is designed as a material deformation valve, in which a fluid opening is released by a material deformation of an elastic material.
  • pumping devices are often designed as Einwesbauteil, and therefore problems with material fatigue phenomena usually play only a relatively minor role.
  • a possible construction results, for example, when a provided with one or more openings tubular element is provided with an elastic hose pushed over it. When pressure is applied to the inside of the tube, the tube expands and, when a certain pressure difference is exceeded, allows fluid to escape from the tube interior to the outside. In the reverse direction, however, a fluid passage is effectively prevented.
  • a meaningful training opportunity may result if at least one fluid branch line is formed in multiple stages.
  • This can be realized, for example, in that a plurality of openings or OrificeEinraumen are connected in series.
  • a kind of intermediate chamber can be provided between the individual openings.
  • the respective geometric position of the passage openings is offset from one another (for example in the axial, radial and / or angular respect). With such a construction, it is possible, for example, to realize a fluid branch line, which has a relatively high flow resistance for passing through fluid, but is still made compact and has a relatively small space.
  • a defined proportion of pumped and / or still to be pumped fluid is branched off via the fluid branch line. This can be done, for example, by appropriately adjusting the fluid resistance of "consumer" and fluid branch line.
  • the fluid branch line is designed as an opening, its fluid resistance over the length and diameter of the opening (possibly also on the number of parallel and / or serially arranged openings) can be adjusted.
  • the portion of the branched off fluid is more than 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80% or 90% and / or the fraction of the branched off fluid is less than 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80% or 90%. In this way, an optimized for the particular purpose pumping device can be formed.
  • the outlet of the fluid branch line is fluidically connected to the fluid input line.
  • the branched off Portion of the pumped fluid for example, in the reservoir from which the fluid input line removes the fluid is returned. In this way, no fluid is "lost", so that a particularly economical pumping device can be realized, Moreover, in the pumping device is not necessarily a fluid leakage into unwanted areas inside.
  • a liquid atomizer in particular a liquid atomizer for a scenting device which has at least one pumping device with the structure described above.
  • the liquid atomizer can also carry out particularly small amounts of liquid. This is particularly interesting in the field of scenting devices, since it is desirable here for reasons of space to be able to use particularly highly concentrated scent. However, so that it does not come to an excessively strong scenting, the discharged amounts of fragrance must be chosen correspondingly small.
  • a scenting device which has at least one pump device with the structure described above and / or at least one liquid atomizer with the structure described above.
  • the scenting device then has the advantages and properties already described in connection with the pump device or the liquid atomizer in an analogous manner.
  • the Scenting device may in particular be a scenting device for a vehicle, preferably for a motor vehicle, preferably for a power-driven land vehicle.
  • the land vehicle may in any way be a rail-bound and / or non-rail-bound vehicle.
  • an application in an aircraft, a watercraft and / or in a building is conceivable.
  • a meaningful embodiment results when the scenting device has at least one actuator device for actuating at least one pump device and / or at least one liquid atomizer.
  • scenting can take place automatically.
  • the vehicle occupants can perceive the scenting over a substantially unlimited period of time.
  • a method for operating a pumping device in which a portion of the pumped fluid and / or the still to be pumped fluid is diverted and in particular is returned to the suction of the pumping device.
  • the method can be further developed in the sense of the further training possibilities already described.
  • the proposed method has the features and advantages already described in connection with the pump device, the Flusstechnikszerstäuber and the scenting device in an analogous manner.

  • the pump sprayer 1 When the pump sprayer 1 is operated by pushing down the spray head 8, the volume of the pumping chamber 3 of the pump 5 decreases, and the fluid contained in the pumping chamber 3 is pressurized. At the same time, the valve ball 10 is pressed into its valve seat 11, so that the input valve 2 is closed in a fluid-tight manner.
  • the lower region of the sealing element 12 touches a stop web 19, which is formed in the outer cladding tube 13. If the spray head 3 is pressed further down, then the sealing element 12 is lifted off from the sealing plate 14 with the aid of the Anschtagstegs 19.

  • the volume of the pumping chamber 3 of the pump 5 increases.
  • the increase in volume of the pumping chamber 3 causes a vacuum to be created in the pumping chamber 3.
  • the valve ball 10 is lifted off the valve seat 11.

  • This makes it possible to achieve a liquid-tight, liquid-tight and / or gas-tight closure of the fluid container 23 from the outside world when the pump sprayer 24 is not actuated.
