Definitions

  • the invention relates to a soap dispenser for liquid soaps, with a piston pump, the cylinder of which is assigned an inlet opening from a soap reservoir in the region of the front side of the piston of a piston unit and whose piston unit at the rear end of the piston via an intermediate piece entering the cylinder with a handle is connected, at least one quantity regulating stop being provided for the piston to differently determine the amount of soap dispensed per pump stroke from an outlet channel.
  • a soap dispenser has become known from EP-A-0 023 975, in which the tubular piston unit is led out of the open end of the cylinder designed in the manner of a freely projecting pipe socket and rests against a handle lever for actuation.
  • This handle lever can be positioned laterally, in order to cooperate with one of three stops, depending on the lateral positioning, which are arranged next to one another for the purpose of quantity metering on an assembly formed by a soap container, a discharge device and the handle lever.
  • the lateral positioning of the handle lever is secured by spacer bushings, so that after the soap dispenser has been assembled, it is no longer possible to adjust the handle lever to a different stroke. This adjustment is therefore not suitable for operation by the user of the soap dispenser, but at most for its basic factory adjustment.
  • the invention has for its object to provide a soap dispenser of the type mentioned, which can be easily adjusted with regard to the amount of soap exiting per pump stroke, in particular an adjustment should be possible even after the installation of the soap dispenser at the place of use.
  • a soap dispenser of the type described at the outset according to the invention in that the cylinder has a cylinder cover penetrated by the intermediate piece, in that the quantity regulating stop for changing the amount of soap dispensed per pump stroke from an arranged along the axes of the piston, there is a stop part which is adjustable and fixable relative to the cylinder cover in the longitudinal direction of the piston and surrounds the axis, a counter stop of the piston being assigned to the inner end of the stop part and / or a counter stop of the handle being associated with the outer end of the stop part.
  • a very precise regulation of the amount of soap applied per pump stroke can be achieved with space-saving compact design, and this regulation can also be changed at any time in a relatively simple manner, namely directly by adjusting the quantity regulating stop.
  • a particularly advantageous embodiment of the subject matter of the invention is that the inlet opening from the soap reservoir opens into the cylinder path of the cylinder, that the piston has a longitudinal channel open at the front piston end and forms a slotted slide valve for the inlet opening with the front piston end, and that the piston further aft has the mouth of the longitudinal channel leading to the cylinder wall, in the movement area of which an inlet opening of the outlet channel starting from the cylinder raceway is provided, the piston closing the inlet opening in a stop position given by the quantity regulating stop.
  • the stop at the end of the pump stroke is in the stop position, ie if the pump stroke is limited by the stop.
  • the stop in the starting position of the piston is in the stop position, that is if the return stroke is variably limited. It has been shown that with such a stop design, the maximum amount of soap per pump stroke is applied in a central position and that the amount applied per pump stroke is increasingly reduced by adjusting the stop in both directions.
  • the stop is designed as a double-sided stop, so that a single stop is suitable both for the limitation of the pump stroke and for the limitation of the return stroke and thus the total length of the stroke is the same for each stop position.
  • a stop that is fixed relative to the cylinder cover in order to limit the return stroke, so that the initial position of the piston is then always the same.
  • a counterstop is expediently formed by a stop ring lying adjacent to a rear piston seal, so that a direct stop load on the piston seal is avoided with simple assembly.
  • the stop has an adjusting thread which, in order to be able to simply fix the stop, is expediently a self-locking external thread.
  • a very safe guidance of the piston which usually extends beyond the rear end of the cylinder cover, is achieved when the on is a sleeve surrounding the intermediate piece, in which the intermediate piece is preferably guided.
  • the stop has the same cross-sections throughout, it being in particular formed by a pipe section.
  • the intermediate piece in one piece with the piston and / or the handle.
  • the intermediate piece is detachably attached to the piston, a piston seal and / or a counterstop being preferably clamped between the rear end of the piston and a shoulder of the intermediate piece.
  • a soap dispenser 1 has a housing 2, which forms an essentially cylindrical, flat soap store 3 in the upper region.
  • the upper end cover 4 of the pot-shaped soap store 3 has an internal thread 5 lying in its central axis, into which the appropriately designed neck 6 of a storage bottle 7 for liquid soap can be screwed upside down in such a way that the neck opening opens into the soap store 3.
  • the cylinder 8 of a piston pump 10 is formed in one piece with this, which lies in an axial plane of the soap reservoir 3 such that its central axis intersects the central axis of the soap reservoir 3 at right angles.
  • a piston 9 is displaceably guided in the cylinder race 11 of the cylinder 8, which piston is designed as a fitting cylinder at its front end and up to its front end face and is thus guided in a tight-fitting manner on the cylinder race 11. Behind the fitting cylinder, the piston 9 has a reduced diameter section 12, behind which a further piston seal 13 is connected. This piston seal 13 rests with two ring lips sealingly and slidably against the cylinder race 11.
  • the piston 9 is provided with a sleeve-shaped design with a longitudinal channel 17, which extends from its front end and lies in its central axis and extends into section 12.
  • a longitudinal channel 17 which extends from its front end and lies in its central axis and extends into section 12.
  • two diametrically located transverse bores are provided in the section 12, which form openings 18 to the annular gap 19 which is delimited by the cylinder raceway 11 and the section 12.
  • the orifices 18 represent the rear outlet of the longitudinal channel 17.
  • the piston 9, which is formed in one piece with the section 12, is formed by a component that is separate from the intermediate piece 14, the two components being releasably braced against one another by a screw 20 lying in their axis.
  • the head of the screw lies at the base of the longitudinal channel 17 in such a way that it leaves the orifices 18 free, the threaded shaft of the screw 20 engaging in a reduced-diameter end section of the intermediate piece 14, which engages centered in a corresponding blind hole at the rear end of section 12.
  • the piston seal 13 is clamped between the rear forehead shoulder 21 of the portion 12 of the piston 9 and that at the front end portion of the intermediate. Piece 14 adjoining ring shoulder 22, the piston seal 13 is clamped.
  • the piston seal lies directly on the forehead shoulder 21 and is supported on the shoulder 22 with the interposition of an annular disk-shaped counter stop 23, this counter stop 23 having an outer diameter which is approximately equal to that of section 12.
  • a return spring 24 in the form of a helical compression spring, one end of which rests against the head of the screw 20 and the other end of which is supported under prestress on the closed front end wall 25 of the cylinder 8.
  • a conical centering projection 26 is provided, through which the associated end of the return spring 24 remains aligned with the axis of the cylinder 8 in that this centering projection 26 engages in this end of the return spring 24.
  • the return spring 24 is constantly under tension.
  • an inlet opening 27 is provided in the cylinder 8, which at the same time forms the associated section of the bottom wall of the soap reservoir 3, which acts as a transfer opening between the soap reservoir 3 and the one located in front of the piston 9 Cylinder chamber 28 is used.
  • the outer ring edge of the piston 9 lying in the plane of the front end face forms a slot slide 29 which closes the inlet opening 27 when the piston 9 is pushed forward, so that the liquid soap located in the cylinder space 28 when the piston 9 is fed further only through the longitudinal channel 17 and the mouths 18 can be displaced into the annular gap 19.
  • the input opening opens tion 30 of an outlet channel 31 for the liquid soap, which is formed by a discharge nipple on the underside of the cylinder 8.
  • the discharge nipple 32 is inclined downwards towards the front of the soap dispenser 1 and has in its interior a check valve 33 in the outlet channel 31 in the form of a spring-loaded ball valve which opens in the discharge direction when there is excess pressure.
  • a sleeve-shaped quantity regulating stop 34 with an external thread 35 is guided, which lies in the axis of the piston, in the inner circumference of which the intermediate piece 14 is slidably guided and whose external thread 35 engages in a corresponding internal thread in the cylinder cover 15.
  • the outside diameter of the stop 34 is only slightly smaller than the diameter of the cylinder race 11, the core diameter of the outside thread 35 being slightly larger than the counter-stop 23.
  • the counter-stop 23 is assigned to the inner end surface 36 of the stop 34, while the outer, annular end surface 37 of an intermediate counter-stop 38 provided on the intermediate piece 14 and lying within the handle 16 can be assigned.
  • the piston unit 39 comprises the piston 9, the section 12, the piston seal 13, the counter stop 23, the intermediate piece 14 and the handle 16, the piston unit forming a structural unit with the cylinder cover 15 and the stop 34.
  • the stop 34 allows both the position of the initial position of the piston 9 relative to the cylinder 8 and its end position at the end of the pump stroke according to FIG. 2 to be determined and thus changed.
  • the external thread 35 is designed as a self-locking thread, so that separate means for fixing the stop 34 in the respectively set position are not required.
