Definitions

  • the invention relates to a soap dispenser for liquid soaps, with a piston pump, in the cylinder track in the region of the front side of the piston an inlet opening from a soap reservoir and whose, having a longitudinal channel open at the front end of the piston, with the front end of a slit slide for the inlet opening forming piston further back has a mouth of the longitudinal channel leading to the cylinder wall, in the range of movement of which the inlet opening of an outlet channel starting from the cylinder raceway is provided.
  • Soap dispensers of this type can have the disadvantage that the amount of soap applied per pump stroke does not correspond to the amount of soap adapted to the respective type of use or the place of installation.
  • the invention has for its object to provide a soap dispenser of the type mentioned, which in a simple manner with regard to the amount of soap exiting per pump stroke can be adjusted, in particular a reduction in the amount applied per pump stroke should be possible.
  • 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 every 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.
  • the stop is mounted on the cylinder cover and a counter stop of the piston is assigned to the inner end of the stop and / or a counter stop of the handle is assigned to the outer end.
  • 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 generally extends beyond the rear end of the cylinder cover, is achieved if the stop is a sleeve surrounding the intermediate piece, in which the intermediate piece is preferably displaceably 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.
  • Piston pump 10 is molded in, 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 a right angle.
  • 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. At the rear end of the piston 9 is connected, for example, a cylindrical intermediate piece 14, which is led out of the cylinder 8 through a cylinder cover 15 at the rear end and carries a handle 16 in the form of a push button at its outer end.
  • 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 exit of the longitudinal channel 17.
  • the piston 9, which is formed in one piece with the section 12, is formed by a component 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 bottom of the longitudinal channel 17 such that it leaves the mouths 18 free, the threaded shaft of the screw 20 engages in a reduced-diameter end portion of the intermediate piece 14, which engages centered in a corresponding blind hole at the rear end of the section 12.
  • the piston seal 13 is clamped between the rear end shoulder 21 of the section 12 of the piston 9 and the ring shoulder 22 adjoining the front end section of the intermediate piece 14.
  • 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 pretensioned 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 an overflow opening between the soap reservoir 3 and the one in front of the piston 9 Cylinder chamber 28 is used.
  • the outer ring edge lying in the plane of the front face of the piston 9 forms a slot slide 29, which closes the inlet opening 27 when the piston 9 is advanced so that the liquid soap in the cylinder space 28 can only be displaced by the longitudinal channel 17 and the orifices 18 into the annular gap 19 when the piston 9 is advanced further .
  • the inlet opening 30 of an outlet channel 31 for the liquid soap opens, 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 non-return valve 33 in the outlet channel 31 in the form of a spring-loaded ball valve which opens in the discharge direction at top 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, during the outer, annular end surface 37 of which is provided on the intermediate piece 14 and lies within the handle 16 Counterstop 38 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.
