Definitions

  • the invention relates to a liquid spray device according to the preamble of claim 1.
  • a liquid spray device of this type is known from GB-A-299 280.
  • the air pump comparable to a bicycle pump is located on a head piece opposite the end of the housing of the liquid spray device.
  • the head piece, a nozzle, can be unscrewed.
  • the liquid can be assigned to the housing of the liquid spraying device in a refillable manner via a lateral nipple or it is held ready by a screw vessel which is laterally assigned to a yolk sac. To this extent, there is a screw vessel refitting.
  • the exposed position of the screw vessel is not just an obstacle to handling; it also leaves the screw vessel largely unprotected.
  • the excess air pressure is passed through a bypass-type outer line into the housing to form an excess pressure air cushion which expresses the liquid via a liquid level and atomizes the liquid steel in the screw-off nozzle with a branch.
  • This liquid spraying device is otherwise difficult to manufacture and laborious to operate, especially since the outlet valve is designed as a shut-off valve sitting on the outer line.
  • a liquid spray device of this type is also known from US-A-4 167 941.
  • the air pump is operated there via a handle on the head piece.
  • the overpressure cushion that builds up is available as a storage force.
  • the liquid is squeezed out by actuating a dispensing valve on the head piece side.
  • the storage device consists of a chamber with a piston disk guided freely therein, which rests on a compression spring which correspondingly tightens with increasing filling of the respective chamber.
  • the overpressure cushion is built up via several small pistons using a rotary movement of the said handle.
  • the pistons which are arranged radially and in opposite directions transversely to the longitudinal center axis of the liquid spraying device, engage with their piston shaft via a control pin in a zigzag-shaped link slot which, taking into account the rotatability of the dispenser head, follows an undulating circular path. That requires a lot of "shooting".
  • the object of the present invention is to manufacture a generic liquid spray device simple, advantageous use so that - even using the interchangeable cartridge principle - a strong, so-called “dry” spray jet is achieved without the need for springs.
  • a generic liquid spray device which is characterized by a simple structure and perfect function.
  • a special spring body cf. US-A-4 167 941
  • a stable spray jet profile is achieved, so that the most varied of media can be applied, and above all the more environmentally friendly cartridge system can be used with advantage.
  • the space is a cartridge receiving space which has an annular gap on the jacket wall side as a compressed air connection right into the head piece.
  • the operating medium can therefore be stored in columns and rooms that are already present, above all taking into account the space accommodating the cartridge.
  • there is the head area i.e. the space available in the head piece.
  • the unit that creates the corresponding overpressure air cushion sits in the end conveniently remote from the head piece.
  • the latter therefore remains easily removable for the insertion of the next, full cartridge or the removal of the empty cartridge.
  • a plug connection nipple arranged on the head piece projects into the cartridge receiving space, through which the inside of the cartridge is connected to the air pressure. This results in a balanced distribution of the overpressure air cushion, one part causing the liquid to be raised or brought in and the other part ensuring surprisingly good atomization.
  • the plug-in connection nipple has a liquid lock.
  • liquid itself is thus prevented from unintentionally escaping into the surrounding overpressure cushion, whereas the air itself reaches the interior of the cartridge via the plug connection nipple.
  • a liquid barrier is achieved with simple means in that the liquid barrier is formed by an annular membrane of the plug-in connection nipple, which rests with its lip edge sealingly on the jacket wall of a riser pipe conducting the liquid into the head piece.
  • the corresponding lip rim in combination with enough flexible material of such a plug nipple appears extremely sensitive; separate formations of such a membrane are therefore not required.
  • the air pump handle is designed as a rotating sleeve which guides itself on the housing of the liquid spray device and is connected to an air pump piston which runs in a cylinder chamber located in the housing.
  • the outer shape of the housing is advantageously used here as a guide means for the rotating sleeve and the inner area for the assignment and design of the cylinder chamber.
  • an advantageous embodiment is achieved by controlling the linkage of the piston / air pump handle functional unit. It is also proposed that the cylinder chamber of a retraction of the housing is formed and the means of the gate control are accommodated in the remaining storage room.
  • the procedure is further specifically such that it is formed by rising grooves on the inside of the air pump handle, into which grooves a stationary, radial guide pin of the housing engages as a so-called sliding block.
  • Such cones can also be taken into account in the injection molding process.
  • the guide pins are fitted with rollers in order to achieve a particularly smooth sliding guide.
  • the grooves are assigned essentially axial insertion shafts, which in the assembled state are blocked by a steeply sloping back comb of the one link part.
  • an advantageous embodiment is achieved by a flatter course of the rising grooves in the final phase of the pumping movement, which also form support pockets for the guide pins in both ends.
  • the support pockets define the end positions, so that a pitch angle for the grooves is applicable, which is far outside the self-locking.
  • the finite limitation of the grooves lies on a working stroke of approx. 135 °. This results in a convenient mode of operation, since the operating hand is not overused, i.e. the ergonomic one Conditions is taken into account.
  • a favorable measure also lies in the fact that the cylinder chamber has a transverse wall carrying the pump valve on the cartridge side, which divides the retraction with respect to the cartridge receiving space of the housing to form a pressure prechamber.
  • This centrally located pressure pre-chamber leads to an even distribution of the overpressure air cushion in a zone immediately downstream of the pressure source, ie pressure pump.
  • the air pump piston carries a piston sleeve with an end annular space.
  • Such an annular space expediently lies in the edge area of the sleeve, thus leading on the one hand to the highly elastic or flexible sleeve lip typical of the sleeve and on the other hand to a stable transition to the remaining central area of the sleeve designed as a pot or plate.
  • the piston sleeve assumes a further function insofar as it also forms the valve tab of an intake valve of the cylinder chamber and a cap screwed to the air pump handle is clipped onto the pot-shaped end drawn in on the housing side. In this way, the piston continues as the inner leg of a rotationally symmetrical U-profile of the handle, which surrounds the lower end of the housing.
  • the plug connection nipple of a perforated holding plate is formed centrally, which is framed between the upper front end of the housing and the screw-connected head piece and continues into a counter-nipple plug-connected to the head piece.
  • the counter nipple is used in the head area to form a rotationally symmetrical Y-channel, the Y-web of which leads to the dispensing valve and the outer Y-leg connects via a transverse channel to a headpiece chamber which is located above the cartridge - Recording room extends.
  • the centering effect of the plug connection nipple leaves a uniform annular space between the jacket wall of the cartridge and the inner wall of the housing.
  • the outlet valve can be actuated by a spray head pushbutton which is spring-loaded in the direction of the closed basic position.
  • the pressure in the cartridge receiving space is identical to the pressure in the end annular space of the piston when the piston is in its retracted end position, it is no longer possible to inflate the cartridge receiving space etc. As a result, the safety of use of the liquid spray device described is also optimal.
  • the dispenser Sp containing the liquid spray device according to the invention is designed as an elongated, essentially cylindrical free-standing device, consisting of a housing 1, a removable head piece 2 and a handle 3. The latter is used to actuate an air pump P.
  • the air pump handle 3 sits on the end of the housing 1 opposite the head piece 2.
  • the air pump P creates an overpressure cushion in the interior of the dispenser.
  • This actuates a discharge valve 4 contained in the dispenser by actuating an outlet valve 4 on the head piece side, by this overpressure air cushion loading both the mirror 6 of the liquid 5 and atomizing it by mixing with the liquid jet.
  • the liquid jet emerges from a so-called nozzle 7 of a corresponding spray device 8.
  • the added air component leads to a dimensionally stable, so-called "dry" spray jet.
  • the overpressure cushion building up in the dispenser Sp is generated in a cylinder chamber 9 of the air pump P. From there, the compressed air arrives in a pressure prechamber 10. From here the distribution takes place in the section of the housing 1 which holds the liquid 5 containing cartridge K is used. It is interchangeably assigned to the donor Sp. It has a diameter such that the cartridge-receiving space 11 leaves an evading annular gap 12 on the jacket wall side, so that compressed air connection is present into the head piece 2, that is to say toward the spray device 8.
  • the cartridge K is designed in the form of a bottle and consequently merges into a neck 14 at its end facing away from the edge-reinforced base 13.
  • the neck 14 arises from the axially approximately drawn-in cover 15 of the cartridge K and has a cylindrical mouth 16.
  • the free space of the housing 1 around the neck 14 and also axially above it ends with a holding plate 17. It is perforated. These are openings 18, one of which can be seen in FIG. 1. Via the latter (18), the compressed air gains connection to the dome-shaped interior of the head piece 2, more precisely that Head chamber 2 '. From here, the branching or division takes place in the sense explained above.
  • connection on the cartridge side is formed by a plug-in connection nipple 19 starting from the holding plate 17 and indirectly connected to the head piece 2. It overlaps into the cylindrical mouth 16 of the neck 14. So there is a kind of pipe coupling.
  • the lower outer edge of the plug connection nipple 19 has a sealing bead 20. Via the plug connection nipple 19, the interior 21 of the cartridge K is connected to the excess air pressure.
  • the liquid 5 is prevented from escaping through the mouth 16 of the neck 14 into the cartridge receiving space 11, for example in cases in which the dispenser Sp is used in an upside-down position for spraying.
  • the plug-in connection nipple 19 has a liquid barrier that only allows the passage of air.
  • it is a relatively thin-walled ring membrane 22. The latter, with its lip edge, which may be pointed, seals and only yields to the air pressure on the jacket wall of a riser pipe 23 which conducts the liquid 5 into the head piece 2.
  • the riser pipe 23 starts from the removable head piece 2. It extends in the longitudinal central axis x-x of the dispenser Sp and extends to the bottom 13 of the cartridge K, but leaving a small distance from it (13), so that the liquid can enter the lower end of the riser pipe 23 unhindered.
  • the other, upper end of the riser pipe 23 is on a central, downward directed, into the mouth 14 protruding nozzle 24, which is coaxial to a spring chamber 25 arranged above, the wall forming an upwardly open pot continues over a pot edge into a bush part 26 open in the opposite direction, which, concentrically and at a distance from the spring chamber 25, extends one of the Top of the holding plate 17 receives outgoing nipples.
  • the latter leaves between its jacket wall and the inner wall of the bushing part 26 an annular channel 28 which is connected to the overpressure air cushion via one or more openings 29.
  • the edge serving as a cross connection between the wall of the spring chamber 25 and the bush part 26 has openings 30. This also clears the way to the closing outlet valve 4 (cf. FIG. 9).
  • the outlet valve 4 consisting of a horizontally embedded annular disk 31 made of elastic material rests on annular walls 32 and 33 arranged concentrically to the longitudinal central axis xx.
  • the inner annular wall 33 forming the spring chamber 25 has transverse channels 34. The latter provide the connection between the spring chamber and a circumferential cavity 35 below the washer 31 ago.
  • a central shaft 36 This has an annular groove 37 at the level of the annular disk 31. At the bottom of the annular groove there is at least one branch channel 38. The latter connects the liquid and air-permeable annular space section of the spring chamber 25 to a central outlet channel 39 which is connected directly to the transversely outgoing nozzle 7.
  • the lower end of the aforementioned shaft 36 extends into the spring chamber 25 and supports the upper end turn of the compression spring 40 loading the outlet valve in the direction of the closed position.
  • the other end turn rests on an annular shoulder between the connecting piece 24 and the wall circumscribing the annular chamber 25.
  • the outlet valve 4 is actuated via a free-standing spray head pushbutton 41 of the head piece 2 which is spring-loaded in the direction of the closed basic position.

  • the holding plate 17 which brings the plug connection via plug connection nipple 19 to the cartridge K is framed peripherally between the upper end edge 1 'of the housing 1 and the head piece 2 connected to it by screws.
  • a centering projection 44 which, despite the elasticity of the material used, since this also has to form the membrane 22, gives the edge section and the entire component a high degree of internal stability.
  • a bell-shaped edge 45 with a corresponding internal thread is formed on the rotationally symmetrical head piece 2, which engages in the corresponding external thread of the housing 1.
  • the described channel situation in the dispenser head leads to the counter nipple 27 in the head piece 2 being used to form a rotationally symmetrical Y channel, the Y web a of which points to the outlet valve 4, the outer Y leg b via the opening 30 to the head piece.
  • the procedure here is further such that the air pump handle 3 is designed as a rotating sleeve which guides the housing 1 of the liquid spraying device and is connected to an air pump piston 46.
  • the lower section of the housing 1 merges into a recess 47 which is clearly recognizable from the drawing.
  • the offset space 48 remaining through the indentation 47 accommodates the means of a link control that displaces the piston 46.
  • the offset space 48 means the space which extends between the cylindrical jacket wall of the recess 47 and the likewise cylindrical inner wall of the handle 3 guided on the housing 1.
  • the slim shape of the dispenser is retained.
  • the link control is formed by two helically rising, raidal inwardly directed open grooves 49. These are located on the inside of the air pump handle 3. They are assigned in a non-overlapping manner and each work with a fixed, radially outwardly directed guide pin 50 of the housing 1 respectively his confiscation 47 together.
  • each of the two guide pins 50 arranged in a diametrically opposed position each carry a roller 51.
  • the latter can be attached loosely be, since the axially extending inner wall of the handle 3 has a locking effect.
  • the same essentially axially aligned insertion shafts 52 are assigned, which in the assembled state, as can be seen from the development in FIG. 7, can be closed with a steeply falling back comb 53.
  • the shoulder Sch adjoining the pressure pre-chamber 10 has support ribs 59 formed on the top side, so that between the surface-stable bottom 13 of the cartridge K and the offset housing inner profile passages 60 remain. As a result, the upper edges of the support ribs 59 form the actual annular cartridge shelf in the housing 1.
  • the piston 46 of the air pump P carries a piston sleeve 61. It is a hat-shaped body made of elastic material such as rubber or the like. In this respect, it is also suitable for performing a double function, which consists in the piston sleeve 61 simultaneously forming the valve flap 62 of an inlet valve 63 of the pump P seated on the piston 46.
  • the piston sleeve 61 is clipped onto the end of a cap 64 which is screwed to the air pump handle 3 and is also cup-shaped and drawn in on the housing side.
