Definitions

  • the present invention relates to a device for portion-wise formation of soap foam, consisting of a storage container for an aqueous soap solution, each with a soap solution metering pump which can be actuated by a single lever and a compressed air membrane pump with membrane piston and reaction spring and a mixing chamber for foam formation.
  • soap dispensers are used in a variety of designs for public and private washing facilities. Are known a.
  • Foam-forming soap dispensers which use a propellant gas made of dichlorodifluoromethane (Freon 12) and whose distribution may only be carried out with great caution for environmental reasons.
  • the device according to claim 2 results in a pulse-like ejection of the soap foam portion and thus prevents clogging and / or dripping after actuation of the device.
  • a valve arrangement according to claim 3 has proven to be particularly useful.
  • the design of the double-acting piston in the compressed air diaphragm pump according to claim 5 has the advantage of high air performance despite the small installation dimensions and high ease of use.
  • the figure shows a preferred embodiment of a soap dispenser developed in comparison to the aforementioned, in a sectional view.
  • G denotes the housing of a soap dispenser.
  • a storage container V filled with an aqueous soap solution - symbolized by an arrow.
  • a mouthpiece 67 extends into the housing G and is connected via a side feed 6 to a cylinder space 4 of a soap solution metering pump 3.
  • a piston 2 with a cylindrical blind bore and a piston outlet opening 7 ' is arranged in the soap solution metering pump 3. This piston 2 is designed like a slide and is sealed on one side by means of an O-ring 52.
  • a bearing journal (not shown) is inserted through the end part of the piston 2 protruding from the cylinder space 4 and is inserted non-positively on its two end sides in a drive bracket 1a.
  • the cylinder space 4 is connected to a mixing chamber 8 via a connection opening 7.
  • In the lower part of the mixing chamber 8 protrudes the nose-like end of a line 18 through which a compressed air D flows in via a compressed air line 5 and can exit via holes 19.
  • the compressed air D is generated by actuating the lever 1 by means of an actuating force F in a diaphragm pump 9.
  • the cylinder 13 of this diaphragm pump 9 has a rubber diaphragm 14a which is guided through concave parts 14c and 14d and which form a double-acting diaphragm piston 14.
  • This membrane holder is screwed through 59.
  • a reaction spring 12 is placed around a piston rod 14b and presses the membrane piston 14 and the actuating elements connected to it into the drawn upper position.
  • the membrane piston 14 can experience a stroke H (downward) and in the process draws air into the cylinder 13 via an air inlet 56 and a flap valve 55.
  • the flap valve 55 is made of rubber and fixed on one side by a holder 57 in the cover of the cylinder 13.
  • a valve 70 located on the left side at the foot of the diaphragm pump 9 closes;
  • the air D located below the membrane 14a is compressed and flows into the compressed air line 5 via a further valve 70 located on the right side of the piston rod 14b.
  • the cylinder space 4 is filled with soap solution except for a small, defined dead space 15, which is essentially predetermined by a sack space 16 with a connecting bore 16 '.
  • the compressed air D flows through the compressed air line 5, the line 18, through the holes 19 into the mixing chamber 8 and generates a coarse-bubble foam there, which is pressed and homogenized by a porous body 20, a so-called frit and is finally expelled through an outlet opening A in a foam deflecting body 22 via a subsequent expansion space 21.
  • a fine, walnut-sized soap foam is available for cleaning purposes.
  • the axes 10 and 11 of the pistons 2 and 14 are perpendicular to each other.
  • the flap valve 54 is made of synthetic rubber and centered on the edge side by a partially circumferential retaining ring 58.
  • the compressed air line 5a shown in dashed lines in the figure, is guided in a circle around a screw pin 68.
  • This screw pin 68 fixes the foam deflection bodies 22, porous bodies 20 and mixing chamber 8 arranged centrally in the housing G.
  • Valves 70 with a cylindrical valve body 71 made of commercially available brass with a valve sleeve 73 and a valve seat 72 made of a commercially available high molecular weight formaldehyde polymer (Delrin) have also proven successful.
  • the subject of the invention can be used very universally and, in particular due to its continuous operational readiness and its simple, reproducible handling, represents an advance in washroom hygiene.
