Definitions

  • the invention relates to a hollow handle for a fluidic cleaning and / or massage device according to the preamble of claim 1.
  • the fluidic cleaning and / or massage device can e.g. an oral irrigator with or without bristles, a denture cleaning device or a skin cleaning and / or massaging device, in particular for the facial skin.
  • the same handle can be used for the various devices.
  • the fluidic massage and / or cleaning device contains at least one nozzle for exiting a water jet. It is advantageously a fluidic oscillator nozzle that emits an oscillating jet. However, it can also be a nozzle that emits a pulsating jet.
  • the source of pressurized water to which the fluidic massage and / or cleaning device is connected can be a tap, e.g. in a bathroom or a water container in connection with an electric pump.
  • Solid active ingredients which are difficult to dissolve in the water flow are known. It has also been proposed to form such active substances in the form of rods and to insert them into the hollow handle of an oral irrigator. Here was the problem that the active ingredient is often attacked too unevenly and too intensely by the flowing water, so that it is used up after a relatively short time and the amount of active ingredient released to the water is uncontrolled and too high. The difficulty also arises that an active ingredient stick breaks early into several parts, which can become blocked in the flow path of the water. If the fluidic cleaning and / or massage devices used contain oscillators which emit a back and forth oscillating cleaning and / or massage jet, it is particularly important that the oscillators are not blocked by particles of active substance.
  • the object of the invention is therefore to show ways and means by which the amount of an active ingredient which is released into the water stream passed through the handle can be adjusted so that in one and the same handle depending on the use of the connected cleaning agent. and / or massage device, various active substances with different solution behavior can also be used in the flowing water.
  • the handle has a dosing chamber or dosing container for receiving a supply of active substance, which contains a device for the continuous delivery of the active substance to the water flow directed through the handle in a selectable small amount.
  • the active ingredient can have any consistency between liquid and solid.
  • the active ingredient can have a powdery or granular structure or can be in tablets or sticks.
  • the active ingredient can also be light or viscous, doughy or pasty. In many cases it is particularly advantageous if it has a rod shape that is as sparingly soluble in the water flow as possible.
  • Fig. 1 shows a longitudinal section through a hollow handle 1 of a fluidic cleaning and / or massage device, e.g. can be an oral irrigator, a facial cleaning shower or a prosthesis cleaning device, which are not shown here.
  • a fluidic cleaning and / or massage device e.g. can be an oral irrigator, a facial cleaning shower or a prosthesis cleaning device, which are not shown here.
  • the hollow handle 1 is connected at its rear, somewhat tapered end to a water hose 2 for supplying water.
  • a water hose 2 for supplying water.
  • an internal thread 3 is provided, into which a closure cap 4 is screwed.
  • a sealing ring 5 is located between the closure cap 4 and the front end face of the handle.
  • the cap 4 carries a sieve 6 at its inner end lying in the handle.
  • the cap 4 also has a central recess 7 for connecting a holder tube 8, of which only the rear insertion end is shown.
  • the holder tube carries e.g. a fluidic oscillator, e.g. forms an irrigator.
  • the fluidic oscillator can also be combined with a brush to thereby form a fluidic toothbrush or a special tooth cleaning device.
  • the brush can also have such a special design that a facial cleaning and / or facial massager is formed.
  • the handle 1 can also be connected to a cleaning and / or massage device in another way. The connection of the handle via the holding tube 8 to a cleaning and / or massage device has been selected as a possible coupling example.
  • the central recess 7 in the cap 4 is conical in the example.
  • the insertion end of the tube 8 is shaped accordingly conically, so that the tube is held on the cap 4 by the frictional engagement of the conical plug connection. It is clear that other types of couplings between the tube 8 and the cap 4 are possible, which need not be shown here.
  • a dosing container 9 is inserted into the hollow handle 1.
  • the dosing container 9 consists of a thin-walled cylindrical sleeve or cartridge, preferably made of plastic.
  • a solid, rod-shaped active substance 11 is inserted into the dosing container, the outer diameter of which in the original form is only slightly smaller than the inner diameter of the dosing container 9.
  • the lower end of the rod-shaped active substance rests on the bottom 10 of the dosing container 9, which is flat on the inside.
  • On the outer circumference of the metering container 9 there are three rib-like evenly distributed over the circumference in the example Projections 12 (Fig. 2), which are supported on the inner wall 13 of the hollow handle.
  • the water flowing through the handle can flow past between the inner wall 12 of the handle 1 and the outer wall of the metering container 9 in order to enter the tube 8 at the upper end of the handle 1.
  • the free space between the outer wall of the metering container 9 and the inner wall of the handle is chosen such that the water can flow down after using the cleaning and / or massage device and switching off the pressurized water source and ventilation of the hose connected to the handle.
  • the dosing container has several holes 14, which the water flows past.
  • the number and size of the holes are selected so that only a certain amount of the active ingredient 11 is dissolved. It is clear that the more holes there are, the greater the amount of solution per unit time of the solid active substance in the flowing water. Depending on the shape and number of holes, the amount of solution of an active ingredient per unit of time can be adjusted or metered.
  • the number and shape of the selected openings in the dosing container essentially depends on the composition of the active substance and its solubility properties in the flowing water. It is advantageous if the dosing container is streamlined at its lower end opposite the water flow, as indicated by dashed lines in Fig. 1, so that the water flow is evenly directed to the free annular space between the dosing container and the inner wall of the handle.
  • the dosing container 9 in the form of a cylindrical sleeve is - in the example case - open at the upper end.
  • the upper end of the active substance stick protrudes somewhat from the dosing container.
  • the sieve 6 of the cap 4 of the handle 1 comes to lie just above the upper end of the active substance stick, so that the sieve 6 acts as a kind of closure of the dosing container 9.
  • the dosing container can, however, also be provided with a cap, indicated by dashed lines, which can be designed so that it can be easily folded down or pulled off for refilling the dosing container.
  • the rib-like projections 12 on the dosing container are designed in such a way that it forms a slight press fit in the handle. Since the handle is tapered at its lower water connection end, the lower end of the dosing container, which is provided with a flow profile, is held at a distance from the lower end of the handle. In this way, water can flow unthrottled into the free annular space between the container and the inner wall of the handle.
  • the openings in the metering container have a selected water permeability.
  • e.g. are relatively fine holes, or a filter-like body with a certain porosity is used in a relatively large cross-sectional hole.
  • a large number of alternative solutions are available to the person skilled in the art in order to adjust the amount of solution of a specific active substance in the water flow by the shape and / or size of the openings, including their water permeability.
  • the rib-like projections 12 on the metering container 9 can also be fixed on the inner wall of the handle 1 and that accordingly a ribless metering container 9 can be inserted into the hollow handle, being supported on the radially inwardly projecting ribs and there forms a press fit in a predetermined position.
  • Fig. 3 shows a modified dosing container.
  • the metering container 9 has on its outer surface a multiplicity of longitudinal grooves 15 distributed uniformly over the circumference, which are delimited by ribs 16 which are supported on the end face on the inner wall of the handle 1.
  • the free spaces delimited by the ribs 16 and the opposite inner wall of the handle 1 form a multiplicity of flow paths 17 for the water flowing past the container on the outside.
  • Holes 1411 emerge in the longitudinal grooves 15, via which the water finds limited access to the active ingredient.
  • the shape and number of the openings in the wall of the metering container are determined by the desired amount of solution of the active ingredient.
  • the ribs on the dosing container or on the inner wall of the handle allow a clamping fit for the dosing container. It may be sufficient if the ribs or the like protrusions ensure that the water flowing past can be distributed evenly over the entire circumference of the metering container and that only a certain surface section is not exposed to the flowing water by one-sided contact of the metering container on the inner wall of the handle. Slight wobbling movements of the dosing container, whose laterally projecting ribs end at a small distance from the inner surface of the handle, have no negative influence on the dosing function.
  • the dosing container can also be provided at both ends with radial flanges which have flow passages for the largely unimpeded passage of water.
  • the dosing containers are located essentially in the center of the handle 1 and determine a free annular space between them and the inner wall of the handle 1, along which the water flows to the cleaning and / or massage device.
  • the metering container 9, 9 ' can also be arranged in the hollow handle 1 in such a way that only a selected partial flow of the total flow passed through the handle flows along the metering container.
  • the dosing container is now in a bypass.
  • the amount of the active ingredient entering the bypass flow can be adjusted.
  • a bypass thus forms a further possibility of determining the amount of solution of the active ingredient.
  • FIG. 4 shows an exemplary embodiment of a handle 1 'according to the invention in longitudinal section, the metering container 9 being inserted in a bypass 18 which branches off from the main flow path 19.
  • the amount of water that can be branched off from the main flow path 19 can be determined.
  • the amount of flow that is passed through the bypass 18 can be selected so small that it is no longer necessary to accommodate the active substance stick 11 in a special dosing container 9, as shown for exemplary embodiments in FIGS. 1 to 3. It may be sufficient to have an effect Insert fabric sticks 11 directly into the bypass 18. In such a case, the bypass 18 with the selected cross section forms the actual dosing container or dosing chamber at its inflow end 20.
  • FIG. 5 and 6 show a further handle 1 according to the invention for the use of an active substance stick 11.
  • a thin flow guide disk 21 is fixedly inserted into the lower end of the handle, which has on its circumference gear-like indentations 22 which are delimited by projections 23, which are supported on the inner wall at the bottom of the handle 1.
  • the active substance stick 11 inserted into the handle 1 originally has a diameter such that it leaves a sufficiently wide annular space 24 between the stick and the inner wall of the handle.
  • the rod rests with its lower end on the flat flow guide disk 21, which protects the lower end face of the rod against an immediate impact of the water flow supplied. In this way, the entire dissolution time of an active substance stick can be significantly extended with relatively little effort. This means that the amount that goes from the active substance stick into solution is significantly less when the disc 21 is used than without it.
  • the disk 21 is designed in the form of a flow line on the upstream side, as indicated by dashed lines in FIG. 5.
  • FIG. 7 and 8 show a further handle 1 according to the invention, which has on its inner wall radially inwardly projecting ribs 12, which hold a cartridge-like dosing container 25 in the center of the handle 1 in a fixed position.
  • the dosing container 25 is shown partially broken away. It is essentially filled with a fibrous material 26 which serves as a storage for a liquid active substance.
  • the fibrous material 26 is connected to a pin 27 which is absorbent and which is guided outwards through a narrowed neck 28 at the upper end of the metering container 25.
  • the upper end 29 of the suction pin 27 protruding from the metering container 25 protrudes into the flow path of the water which is passed through the hose 2 into the handle 1 and along the free annular space between the metering container 25 and the inner wall of the handle 1 to the upper end of the handle 1 flows where it comes into contact with the suction pin end 29, via which the liquid active ingredient is released from the fibrous material to the water in a selectable amount.
  • the suction pen 27 can also be dispensed with if the fibrous material 26 can itself be guided to the outside via the opening in the metering container 25. This is particularly possible if the fibrous material is not destroyed by the water flowing past.
  • the dosing container 25 is constructed similarly to a felt-tip pen, which is replaced by a new dosing container 25 after the liquid active substance has been consumed.
  • the outlet end of the metering container 25 with the suction pin 28 protruding from it or with the fibrous material 26 guided out of it can also be directed against the water flow.
  • FIG. 9 and 10 show a further handle 1 according to the invention, which, according to FIG. 8, has radially inwardly directed ribs 12 on its inner wall, which hold a cartridge-like metering container 29 between them, which is cut in FIG. 9 within the handle 1 and is shown in Fig. 10 in the view. absorbs a certain amount of a liquid active substance in its hollow interior.
  • the handle 1 has a specially designed closure cap 32 which can be coupled at its upper end with a cleaning and / or massage device, not shown.
  • the closure cap 32 can be screwed onto the handle 1.
  • Fig. 11 shows a section along the lines XI-XI in Fig. 9. This makes it clear that the cap 32 centrally in its lower end has a special coupling part 33 which is held by means of radial ribs 34 on the inner wall of the cap 32.
  • the coupling part 33 has a central opening 35, to which a suction tube 36 connects.
  • the outer wall 33 'of the coupling part 33 and the opposite inner wall 37 of the closure cap 32 are designed such that a Laval-shaped ring nozzle 38 is formed between the opposite walls 33', 37, the outlet opening. 35 of the coupling part 33 lies approximately in the narrowest area of the ring nozzle 38.
  • the inner cross section of the tube 36 is now selected such that the liquid active ingredient rises from the metering container by capillary forces in the tube to the outlet opening 35 of the coupling part. If a flow of water is passed through the handle 1 and is supplied to the handle from a pressure source via the hose 2, then the water flows along the free annular space between the metering container 29 and the inner wall of the handle 1 to the upper end of the handle and thereby passes through the Lavall's ring nozzle 38. In the area of the outlet opening 35 in the narrowest cross section of the ring nozzle 38, a negative pressure is formed, by means of which liquid active substance is sucked out of the tube, a certain amount of the liquid active substance being added to the water.
  • the dosing container 29 can also be closed in a manner other than by an aluminum foil. Thus, a ball sealing the outlet opening can be pressed into its neck 30 and pushed into it to open the dosing container.
  • the tube 36 for sucking the liquid active substance from the dosing container can also be dispensed with if the dosing container according to FIG. 7 is filled with a fibrous material 26 for storing the liquid and an absorbent pin 27 in contact with the fibrous material 26 through the central outlet opening 35 of the coupling part 33 comes to lie outward in the narrowest cross section of the Laval ring nozzle 38.
  • FIG. 12 A corresponding embodiment according to the invention is illustrated in FIG. 12, in which the corresponding parts of FIGS. 7 and 9 are provided with the same reference numerals. It is made clear that the suction pin 27 through the opening 35 of the coupling part 33 to approximately the narrowest cross section of the Laval. Ring nozzle 38 protrudes.
  • the dosing container 26 has a protective cap, not shown here, which is removed before the cap 32 is screwed onto the handle before it is inserted into the handle to protect the suction pin 27 protruding therefrom.
  • Fig. 13 shows yet another embodiment of a handle according to the invention, which has a cap-like attachment 39 on the outside, which delimits a space 40 between itself and an outer wall section of the handle 1, which is opened by opening e.g. plug-like or screw-like closure 41 is accessible in order to be able to fill an active substance into the space 40.
  • the space 40 communicates with the interior of the handle via at least one bore 42 in the wall of the handle. To the extent that a stream of water is passed through the hollow handle 1, an adjustable small proportion of the active ingredient is sucked out of the space 40 into the stream of water.
  • the active ingredient is liquid.
  • the diameter of the bore 42 is more or less narrow, via which the liquid only gets into the handle when a water stream flows past the bore within the handle and carries liquid agent with it from the bore 42.
  • the bore 42 needs to be less narrow in cross-section if it is a relatively viscous active ingredient.
