Definitions

  • the invention relates to a device for generating and dispensing of foam, especially soap foam.
  • Such devices are used at washing points in, for example, bathrooms and toilets installed, for example for hand washing a dosed Generate and dispense amount of lather. That’s enough a simple operation of the device by hand to a certain Generate amount of foam and dispense at the same time.
  • Such Devices can be part of a fixed over or at the wash station installed foam dispenser or as an attachment immediately be arranged on a liquid storage container.
  • a soap foam dispenser is known from US Pat. No. 1,896,624. which consists of a housing with a volume-adjustable, cylindrical Air chamber and from a coaxially arranged thereon Device for simultaneous promotion for air transportation foamable liquid consists of a container, the Installation from one into a suction side with a check valve provided chamber retractable from the actuator for air compression Plunger is formed and both the air chamber and the chamber provided with the check valve in the device with a foaming chamber in connection to which the Foam outlet duct connects.
  • the housing part that the air chamber encloses, serves as an actuator for air compression and their conveyance into the foaming chamber, the in a part of the foam outlet channel attached to the side of the housing is arranged.
  • the device consists of a housing with a volume-adjustable, cylindrical air chamber and a coaxially arranged device for the simultaneous delivery of foamable liquid from a container for air delivery, the device consisting of a chamber provided on the suction side with a check valve and retractable by the actuating element for air compression Plunger is formed and both the air chamber and the chamber provided with the check valve are connected in the device with a foaming chamber to which the foam outlet channel connects.
  • a piston with a central insert is arranged in the air chamber, which is firmly connected to the piston.
  • the unit which is made up of insert and piston, is supported by a spring against the bottom of the air chamber.
  • An air duct is arranged in use, which connects the foam chamber arranged centrally in the insert to the air chamber.
  • the insert protrudes, directed towards the foam chamber and firmly connected to it, the open end of the plunger, which is provided with a conveying channel and is displaceable in the device for conveying liquid, and a foam suction valve is arranged in the air channel before it flows into the foaming chamber, which valve also coincides with the air channel connects the foam outlet channel.
  • Fig. 1 there is the device according to the invention from a housing G with a volume-adjustable, cylindrical Air chamber 1 and from a coaxially arranged device 2 for the simultaneous promotion for air transportation foamable liquid from a container V, the device 2 (see also FIG. 5) from one to one on the suction side Check valve 3 provided chamber 6 of the actuating element 4 for the air compression retractable plunger 5 is formed and both Air chamber 1 and the one provided with the check valve 3 Chamber 6 in the device 2 with a foaming chamber 8 in Stand connection to which the foam outlet channel 9 connects.
  • the air chamber 1 is a piston 10 with a central one Insert 11 arranged, which is firmly connected to the piston 10 is.
  • the unit formed from insert 11 and piston 10 is supported by a spring 12 against the bottom 13 of the air chamber 1.
  • an air duct 14 is arranged, which Foam chamber 8 arranged centrally in the insert 11 the air chamber 1 connects. Raises into the insert 11 against the Foaming chamber 8 directed and firmly connected to it, the open end 7 of the provided with a delivery channel 5 'in the device 2 for moving liquid Plunger 5, and is also in the air duct 14 before it Mouth 15 in the foaming chamber 8, a foam suction valve 16 arranged, the air channel 14 with the foam outlet channel 9 connects.
  • the piston 10 and insert 11 formed unit, the total of the actuator 4 for the change in volume of the air chamber 1, formed from several parts, but all of them firmly together are connected.
  • a third sleeve 22 is arranged, which is also firmly in use 11 sits.
  • this sleeve 22 In the bottom 23 of this sleeve 22 there are several openings 24 arranged together with an elastic ring 25th form the foam suction valves 16.
  • a hood 26 On the whole mission 11 sits a hood 26, which also contains the foam outlet channel 9, from which a suction bore 27 the suction connection to the foam return valves 16 manufactures.
  • This hood 26 also has one Recess 28 for a pull bracket 29 which in the direction of arrow P is adjusted by a hand lever 30 when this is in Direction of arrow P 'rotates about its axis 31 on housing 1.
  • the piston 10 is pressed into the air chamber 1 and compressed the air flowing through the openings 14 'into the air duct 14, 14 '' and from there to the annular mouth 15 in the Room 21 (premixing chamber) arrives, where the air with the foam to be foamed Liquid meets.
  • the whole unit from piston 10 and insert 11 is also the plunger 5 firmly connected therewith (see FIG. 5) into the chamber 6 pressed.
  • the plunger 5 When the plunger 5 is immersed, it becomes the delivery channel 5 'leading cross holes 5' 'free, and that from Plunger displaced liquid rises in the delivery channel 5 ' at the top in the foaming chamber 8.
  • the one formed in this Foam then emerges at the end of the foam outlet channel 9 and becomes taken from the user's palm there.
  • the unit consists of piston 10, insert 11 and plunger 5 back by the spring 12.
  • This Reset process causes new liquid to enter the chamber 6 of the device 2 is sucked in that in the air chamber 1 Vacuum arises, which opens the foam suction valves 16, so that the negative pressure via bore 27 also in the foam outlet channel can take effect and the residual foam there in the Cavities of the insert 11, i.e. in the spacious part of the Sucks air duct 14 back, from which the foam or any liquid which has regressed again the next time it is pressed is carried away by the air.
  • FIGS. 4 and 6 The same principle shown in FIGS. 4 and 6 works Device designed for a direct attachment to a liquid container V 'is determined. Corresponding parts of this embodiment are provided with corresponding reference numerals, so that a further description is unnecessary.
  • the housing G in the embodiment according to FIG. 1 is hereby formed by the neck H of the liquid container V ', in which the Air chamber 1 is screwed in.
  • a stop 32 in the embodiment 1, the stroke of the piston 10 with its Insert 11 is limited in the embodiment according to FIG. 4 by a stop ring screwed onto the wall 33 of the air chamber 1 34 formed.
  • FIGS. 1 and 5 are of slightly different constructive Apart from details, largely identical. Glides here and there the plunger 5 in a stationary sealing sleeve 35, and also the check valve 3 has a spring 36 which also participates in the reset process.
  • the air inflow opening 14 'adjusts in the embodiment 4 and 6 represent an annular gap, while in the embodiment 1 and 3 from several such openings 14 'is formed on one with respect to the central axis 37 upper semicircle 38 are arranged, what at this embodiment ensures that sucked back foam cannot get into the air chamber 1.
  • the air chamber 1 with the unit of piston 10 and insert 11 immediately sits in the neck H of the liquid container V ', sits at the Embodiment according to Fig. 1 of the liquid container V in one Neck H of housing G provided with a ventilation valve 39, in which, as shown, the device 2 with the air chamber 1 is arranged, i.e. the foamable liquid is in this Trap sucked out of the chamber 40 of the housing G.
