Definitions

  • Device for vacuuming individual objects for example insects, flies, wasps and the like.
  • the invention relates to a device for suctioning off individual objects, for example insects, flies, wasps and the like, with a pulse suction device which has a pump element which can be moved by an energy store and triggered by a trigger, and a suction chamber which has a disposable Locking device is connected to a suction nozzle.
  • DE-PS 270 634 shows a piston which can be moved in a cylindrical housing by means of a tension spring designed as a tension spring, the piston rod of which is designed as a suction pipe and can be connected to the lower suction chamber by a weight-loaded closing flap.
  • a tension spring designed as a tension spring
  • the piston rod of which is designed as a suction pipe and can be connected to the lower suction chamber by a weight-loaded closing flap.
  • This also serves as a collecting space and contains an insecticide.
  • the device is tensioned by pushing in the suction pipe and held by a spring-loaded cross slide that engages in a circumferential groove of the suction pipe.
  • the device can only be used in a nearly vertical position with the suction pipe at the top. Since, during the triggering process, the negative pressure which arises in the suction space first has to propagate through the relatively long suction tube, the negative pressure can only slowly build up there. In addition, pushing the nozzle pipe presents considerable risk of injury.
  • the invention is based on the suction device defined at the outset and pursues the task of making this device as compact and handy as possible in such a way that, with a reduced risk of danger, handling and the target process are facilitated in such a way that the object is abruptly as close as possible greater negative pressure is built up before the object can escape.
  • the suction nozzle, the suction space and an intermediate, separately emptied collecting space are assigned to a device housing enclosing the range of motion of the pump element in a tightly fitting manner.
  • z. B. can usually approach a fly with your finger up to about 1 cm before it flies away.
  • a suction nozzle required for sucking up a fly has consistently smaller cross-sectional dimensions than the index finger, and one only needs to exert a short impulse-like suction blow in order to reliably lift the object from a soft surface even at the short distance.
  • the volume of the surrounding medium to be suctioned off can then easily be limited in such a way that the substrate or any other adjacent soft materials are not impaired. It is thus easily possible to lift the fly from the surface of a cream cake, for example, without the cream becoming dirty or even deformed or entrained by the suction air flow.
  • Suction energy and nozzle cross-section must somehow be related to the object to be suctioned.
  • small objects such as insects
  • an inexpensive configuration is possible as a light hand-held device which can be pushed as a whole up to the object. Vibrations noticeable by the object can only occur when the suction flow has already started.
  • the pump element Since the pump element is tightly shielded on all sides, there is no risk of injury, and there is no need to estimate larger distances during the aiming process. Contamination of the suction space is prevented by the emptying collecting space and thus the guidance of the pump element is improved.
  • the captured or collected objects do not suffer any separate deformations and can therefore be released again later or can be used appropriately. Above all, however, the close combination of interlocking functional spaces ensures an abrupt build-up of the negative pressure at the suction nozzle.
  • Fig. 1 is a partially cut in the nozzle area
  • FIG. 2 is a partial view of this device in the area of the trigger seen from above in Fig. 1,
  • FIG. 3 shows a longitudinal section through the suction device prepared for the tensioning process in the plane of FIG. 1,
  • FIG. 5 shows a longitudinal section corresponding to FIG. 3 through the tensioned device in two operating positions of the tensioning element
  • FIG. 6 shows a view of the nozzle from the left in FIG. 5
  • 7 shows a front view corresponding to FIG. 6 of a comparable nozzle tube with a trap closure
  • FIG. 8 shows a longitudinal section through this nozzle along the line VIII-VIII in FIG. 7.
  • the supporting part of the suction device shown is a tubular housing 1, which carries a catch unit 2 on its front side and also a holding and triggering element 3 for a piston 4, which is pressed against an end cap 6 supported on the housing by a tension spring 5 designed as a helical compression spring becomes. Between this end cap and the piston a return spring 7, which is also designed as a compression spring, is attached.
  • 1 in FIG. 1 denotes a nozzle cap and 9 denotes a partially conical stamp cap, which according to FIGS. 3 and 5 can optionally be attached to the end cap 6 as a pressure stamp on the outside.
  • the housing 1 has a rear cylinder part 11 serving as a pump cylinder for the piston 4, the free end of which is delimited by a narrow inner flange 12 which merges forwardly into a connecting piece 15 by means of an intermediate flange 13 via a cylinder extension 14 enclosing the tension spring 5 .
  • the piston 4 divides the cylinder space into a front suction space 16 and a rear pressure space 17.
  • the housing wall is penetrated by a radial shaft 18 with a rectangular cross-section, which extends outwards within a neck sleeve 19.
  • the multiply bent release lever 21 is passed through during assembly, which is connected in one piece to the retaining ring 22 of the holding and release element 3 designed as a stamped part.
  • This element preferably also exists like the two springs 5, 7 made of spring steel, while the remaining tube parts are all made of an inexpensive and elastically deformable plastic such as PVC.
  • the connecting piece between the release lever 21 and the retaining ring 22 is a web 23, which is sealed in the shaft 18 by the neck sleeve 19 and seals under elastic tension. increases. Starting from the radial plane of the web 23, the loaded release lever 21 is arranged so as to protrude obliquely outwards so that there is sufficient pivoting angle for the release process against the cylinder part 11,
  • the retaining ring 22 is also deflected toward the piston 4 by approximately 10 °.
  • the inside diameter of its recess 24 is only slightly larger than the outside diameter of a pipe socket 25 of the piston serving as a retaining attachment.
  • This pipe socket also has a conical insertion bevel 26 on the outside for the recess 24 of the retaining ring.
  • the pipe socket 25 extends from a radial central wall 27 of the piston, from which an inner cup part 28 and an outer ring flange 29 are also formed on the opposite side. While the inner part of the middle wall 27 itself forms an annular shoulder 31 for the tension spring 5, a support shoulder 32 for the return spring 7 is formed on the outside of the inner pot part 28.
  • Two ring beads 33, 34 formed on the outside of the ring flange 29 and a resilient wedge-shaped tapered end lip 35 serve for guiding on the inside surface of the housing-cylinder part 11.
  • the outside diameter of the parts 33 to 35 is only slightly larger than the inside diameter of the Inner flange 12 that the piston as a whole through elastic deformation through the rear opening of the cylinder
  • OP part 11 can be pressed.
  • the end cap 6 is also used, whose ring flange 37 provided in the outer part with air outlet slots 36 also engages behind the inner flange 12 with two outer ring beads 38, 39. From the bottom 41 of the end cap 6, an annular connector 42 also projects to the bottom of the pot part 28. In this way, the end lip 35 is relieved of axial pressure forces.
  • the stamp cap 9 forms an outer truncated cone 43 and an inner cylinder flange 44 which, in the operating position FIG. 1, sits with an adhesive seat on the cylinder extension 14 and thereby shields the entire catching unit 2 from the outside.
  • An inner bead 45 is formed on the free edge of the cylinder flange 44 and engages behind an annular bead 46 of the end cap 6 and thus forms an easily releasable snap-in connection.
  • the catching unit 2 essentially consists of a pot-shaped cage 47 with a short nozzle tube 48.
  • the cage 47 is screwed into the connecting piece 15 until it rests against its ring flange 49.
  • the ring flange 49 is connected to the base 51 by axial ribs 52, between which segment-shaped circumferential slots 53 are formed.
  • the nozzle tube 48 is screwed into the ring flange 49 with a threaded shoulder 54, in which a valve flap 56 is articulated so resiliently at its suction end 55 that one end 57 is so resilient that the flap is normally so close to the narrow gap 58 opposite wall of the nozzle tube is held so that the objects to be caught can no longer escape.
  • the flap is pivoted to the articulation side by a suction air flow, so that objects sucked in are formed jointly by the parts 47, 48 of the catching unit 2
  • the collecting space is also included when the entire catch unit is removed from the connecting piece 15 by unscrewing the cage 47. Even with separate transport, the nozzle cap 8 shown in FIG. 1 can be put on for securing.
  • the suction space 16 has reached its smallest cross section.
  • the suction resistance can be reduced even further by using a trap lock 61 according to FIGS. 7 and 8.
  • a trap lock 61 close behind the nozzle 55 on the inside side of the nozzle tube 48 individual plastic fibers 62 fastened with one end, while their free ends converge towards the nozzle axis 63. In this way, the remaining cross-section between the free ends can also be relatively small and better adapted to the objects to be caught.
  • the piston 4 or another pump element does not necessarily have to be moved in a straight line; a swiveling movement can also be advantageous.
  • a metallic tension spring a rubber, plastic or gas pressure spring can be used, and one can also store electrical energy, for example by means of a capacitor, and supply it to an electromagnet to be operated in pulsed fashion for driving the pump element.
  • An injector or ejector can also be used to build up the aspirating blow.
  • the suction power is basically determined by the cubic capacity and stroke time. The shorter the path from the suction chamber and the larger the cross-sectional relationships of the pump element and nozzle, the greater the negative pressure effective at the nozzle. Usually here you come with ratios from twenty to twenty five, 'but it may be appropriate for different purposes well to increase the ratio to Obst ⁇ thirty to over one hundred. This ratio can also be changed by replacing the nozzle tube, which, moreover, has to be adapted to the size of the objects to be captured. The gap or mesh widths of the cage 47 must also be adapted to these.
  • the surrounding medium is usually air, but can also be another gas or liquid. Otherwise, the invention is not limited to the suction of small objects, but can be adjusted if the advised also be used for much larger objects. In this way, quite diverse application possibilities open up.

Abstract

Un boîtier tubulaire (1) porte à l'avant une unité de saisie (2) et encore un élément d'arrêt et de déclenchement (3) pour un piston (4) qui est poussé par un ressort (5) contre un capuchon d'extrémité (6) maintenu en appui sur le boîtier. Un ressort de rappel (7) est disposé entre le piston et le capuchon d'extrémité, lequel présente des fentes d'entrée d'air (36) pour la chambre de pression (17). Une cage (47), vissée dans un manchon de liaison (15), munie de fentes (53) sur son pourtour , s'étend dans la chambre d'aspiration (16). La tuyère d'aspiration (48), pourvue d'un clapet à sens unique (56), est vissée au bout de la cage. Hors service, le capuchon de pression (9) est placé sur la tuyère et sert, dans la position d'engagement avec le capuchon d'extrémité (6), d'organe de tension pour le piston (4) dont le tube (25) s'engage dans l'anneau de retenue (22) et se verrouille par un léger mouvement de recul. Si l'on applique la tuyère d'aspiration (55) de manière étanche sur un objet et que l'on fait basculer l'anneau de retenue (22) par pression sur le levier de déclenchement (21), le piston (4) revient brusquement en arrière sous l'action du ressort (5). Ainsi l'objet est aspiré par la tuyère (55) le long du clapet (56) jusque dans l'enceinte collectrice (59).
