Definitions

  • the present invention relates to a metering pump for liquid or cream-like soaps according to the generic term of claim 1.
  • Known soap dispensers are based on a dosage of the soap solution, by a pump, which has a slide-like piston and the soap from one storage containers arranged overhead, via an intermediate container, dosed in portions and washed for hands releases.
  • the slide having a cylindrical cross section is on one long side with a circumferential groove and one seal ring inserted in it and in one one end of the cylinder.
  • a Coil spring pushes the slide of the actuation direction opposite, up to a stop, whereby the thereby formed cylinder space via a connecting hole to Fills the intermediate container with soap solution.
  • the soap solution flows in the slide over a longitudinal bore, over a groove open downwards and an outflow channel in the cylinder receiving a soap Palm (the offered hand).
  • the dosing pump should also be without major design changes be equipped with an electric drive and yourself also suitable for contactless battery operation.
  • the medium is dispensed as in any other slide pump; the sealing element lies on the working stroke rear shoulder of the annular groove and seals in conventionally the slide opposite the cylinder space.
  • the first sealing element is during the entire dosing process, i.e. during the return stroke (filling process) and of the working stroke (discharge) tight.
  • a donor realized according to the teaching of claim 1 shows a higher one compared to conventional dosing pumps Dosing accuracy as there is no foaming in the cylinder chamber he follows. Required due to lower fluid dynamic friction he also has less energy to operate.- This works is particularly positive for battery-powered, contactless working donors.
  • the check valve at the end of the outflow channel is detachably arranged and its valve cap at the same time contains the outlet nozzle of the outflow channel. This allows easy cleaning and rinsing if necessary of the whole device with water.
  • the slider preferably contains a blind hole-like rear Center hole with a clutch spring (leaf spring). This makes coupling pins easy to connect, which among other things a use of the same slider in different Allows donors with differently trained drives.
  • the solution to the task is particularly economical Use a round seal, also called an O-ring, because this is commercially available and is also an excellent one Rolling behavior for the shift within the width of the has annular groove.
  • groove widths the larger are than 1.5 times the diameter of the O-ring.
  • the soap solution performs at rest Slider over a hole protruding from the end face and in the area of the second annular groove, too. - This causes automatic venting of the dosing pump.
  • FIG. 1 denotes a soap dispenser, which in the usual way has a housing 2 and from it Underside of an annular actuating lever 3 protrudes.
  • the A lever outlet 4 is located in front of the actuating lever 3.
  • a transparent viewing window 5 embedded, behind which is a colored marked Level indicator 6 is located. With an arrow that is Direction of actuation PH drawn.
  • FIG. 2 shows a soap storage container 7 with an attached intermediate container 8, which Has cover-shaped cover surfaces 8 '.
  • intermediate container 8 protrudes a plug-on and plug-on part 9, which in the usual way an overhead soap bottle V records.
  • a soap solution passage 10 In the lower part of part 9 is a soap solution passage 10, which when filled Soap bottle V is the indicated level N of the soap solution S in container 7. The connection necessary for this to the outside air is through a compensating hole 40 created in the cover surface 8 '.
  • a cylindrical soap solution supply 13 is provided, which with a central bore 14 in the cylinder Dosing pump 15 opens.
  • the inside of the pump 15 has a cylindrical dosing chamber 17, which in turn with a soap outlet 16 and which is connected by an in Valve ball 25 mounted on a valve seat 26 is completed is.
  • the valve ball 25 is acted upon by a spring 27, which is centered in a pressed-on valve cap 24 and which has a central outlet nozzle 28.
  • a vertically arranged reinforcing rib 37 is located 2 in the axis of symmetry of the arrangement; likewise a cylindrical support 39 for longitudinal guidance of the Drive and clutch means.
  • Piston 18 which acts as a slide known per se.
  • this cylindrical slide 18 In the rear part of this cylindrical slide 18 is a notoriously known ring groove 19 with one Round seal 20, a commercially available O-ring, embedded and seals the dosing chamber 17 from the dosing pump 15 their outside area.
  • annular groove 21 In the front area of the slide 18 there is another annular groove 21 let in, which however compared to the usual ring groove 19 is broadened.
  • the circular seal located in the annular groove 21 22 is identical to the round seal 20.
  • the slide 18 has a bore 36 contains and on its front side St a central, concave Has recess 23.
  • a tubular coupling pin 29 is in the bore 36 inserted, in the opposite longitudinal grooves 30 'each a clutch spring 30 arranged on the end of the slide 18 intervenes.
  • This spring 30 also serves as an end stop for the return stroke RH and prevents an unwanted Exiting from the cylinder space 17.
  • the coupling pin 29 At the rear end of the coupling pin 29 is in its bore 41 an actuator 31 used, which a lateral recesses 32 and 33 and a coupling lug 38 having; the coupling lug 38 is in the recess 33 engaged.
  • This coupling pin 29 is for a manual Actuating lever - not shown - provided and is designed according to the respective drive means and adapted to this; the same goes for that Coupling piece 29. This allows a single slide 18 to be used for any kind of mechanical drive.
  • the sectional view Fig. 4 shows the symmetrical to Center arranged upper grooves 34 and the like lower grooves 35; cut lines are also shown A - A and B - B.
  • FIGS. 5 and 6 show the corresponding longitudinal sections A - A and B - B, the Section B - B, Fig. 5, through the longitudinal axis of the Slide 18 and coupling pin 29 formed arrangement guided -
  • the functionally necessary annular gap in the widened Annular groove 21 is designated RS.
  • the metering pump according to FIG. 2 shows surprising effects:
  • the one in the front of the slide also has a favorable effect 18 recess 23 recessed, but this acts as a kind of hydraulic spring, since it is in the pump stroke on the one hand PH the slide 18 when it hits the bottom of the dosing room 17 dampens and on the other hand - with a minimum of included Soap solution - the breakaway torque of the slide 18 reduced on the return stroke RH.
  • the pump housing can be made in one piece with the container part are formed, like the sectional illustration in FIG. 2 shows impressively.
  • the subject of the invention is of course not on Limited soap dispenser; it can be, for example also use for dosing pumps in foam dispensers.
  • the actuation force reduced by the subject matter of the invention offers this for installation in battery-powered devices on.
  • the uninterrupted service life of non-contact workers Soap and foam dispensers can be used with the Use of weaker drives significantly lengthen what especially in irregularly used public washrooms the operational readiness of the foam and Soap dispenser increases and at the same time their maintenance costs reduced.
  • the entire arrangement can be carried out very economically known die-casting processes with inexpensive polymer materials produce.
