Definitions

the invention relates to a portable suction device according to the preamble of claim 1, for liquids or liquid / air mixtures.
the suction devices according to the invention have a suction mouth, a suction port in fluid communication with the intake port, which opens into a suction container, and a suction channel connecting the suction container with a vacuum source.
Means for separating the air flow from the other portions of the sucked flow are provided in the suction material container, the suction channel protruding with a pipe socket into the suction material container, which is arranged between a first wall section and a second wall section of the suction material container opposite the first wall section.
Portable suction devices for liquids or liquid / air mixtures of this type are known from US 4993106 A known.
the known suction devices while used to absorb a liquid / air mixture. This can be done as in the case of said device for absorbing liquid, for example from a table top.
Another application of the portable suction devices is the removal of windows and the suction of the liquid, which was collected via a Abziehlippe during removal.
the known devices initially have a separation chamber, in which the moist fractions are separated from the air stream from the aspirated liquid / air mixture. Furthermore, any solid, such as dust or sucked foreign bodies, is separated from the air flow here.
the vacuum source necessary for suction is connected to a suction channel, which projects into the device with a pipe socket.
a suction channel which projects into the device with a pipe socket.
this suction container is both deposition chamber and reservoir for deposited substances or liquids.
the object of the invention is therefore to provide a suction device in which the entry of liquid into the suction channel is minimized.
the Schwapptik is formed as a flat disc, which is plugged onto the projecting into the suction container suction.
the Schwapptik on a central region with a through hole, which may be reinforced by a tubular sleeve. Through the passage opening the suction channel is then inserted.
the Schwapptik can be arranged for example in a horizontal device above the horizontal plane through which the axis of the suction channel and, if this is concentric with the suction, the intake passage. In this case, only the central area, which is necessary for attaching the Schwapptikes to the cylindrical suction channel, partially disposed below this center plane.
form-locking elements are provided on the suction and on the Schwapptik, which prevent false uncovering, especially with downwardly directed wall of the slosh guard. This is particularly useful if the user can disassemble the individual parts for cleaning, so there is a risk that he could build them together again in the wrong way. Indeed, most users will fall into error that the anti-slosh wall should be directed downwards from the mid-plane, but that will not lead to a satisfactory result. It is not the task of the Schwapptikes to divide the suction container into two separate chambers, but he should only prevent excessive, dynamic water movements when the device is tilted or even operated overhead.
the Schwappschutz itself is preferably made of an elastic material, since this additionally acts by absorbing damping by its spring action. In the region in which it is not at a distance from the wall of the suction-material container, it can reach as far as the wall and touch it. Alternatively, it can also leave a gap between itself and the wall, since it essentially depends on the fact that a wave motion is prevented in this area. A small gap between the Schwappstoff and the wall of the suction container is not a hindrance.
the antiframing protection is preferably made of a hydrophilic material.
the lower edge of the Schwapptikes so the edge having a maximum distance to the opposite wall of the suction material container, be curved outwards and downwards, so that liquid adhering to the slosh, is derived at this run down to the outside.
the anti-slosh may also have at this lower edge to the front and / or rear-jumping heels, which may also be unwound outwards and downwards and prevent drops from forming on the lower edge.
a suction device having a suction mouth 1 in the front region, which is formed wide and a Abziehlippe for withdrawing liquid from a hard surface, for example a window has.
the device has a housing which has a handle 5 in the upper area. Such devices are usually held in the hand and used for cleaning windows. In the rear area, the device has a handle receptacle into which an extension handle can be inserted. In this way, even large windows can be cleaned.
FIG. 3 are the essential functional parts of the in the Figures 1 and 2 shown suction device shown schematically in a side view.
the suction device has the suction mouth 1 in the front region. From this suction mouth 1 extends here visible only with its rear part intake 3 into the suction container 2.
the suction container 2 is used to separate the air flow from the other absorbed parts via a separator and for receiving the separated parts.
the device can be used to absorb a liquid / air mixture or to absorb solids. In both cases, the air is separated from the liquid or solid material flow and passed through a suction channel 4 through the vacuum source arranged behind it to the outside.
a Schwapptik 6 is provided between the rear third of the suction container 2 and the area present before.
This Schwapptik 6 consists in the illustrated embodiment of a flat disc, which is placed on the suction channel 4 and extending from the central plane upwards.
the suction material container 2 shown here has essentially a quadrangular cross-section, with the anti-slosh 6 extending from the upper halves of the side walls into the middle or from the suction channel 4 to the ceiling.
the Schwapptik 6 thus covers the upper half of the cross-sectional area, while the lower half remains continuous.
liquid will therefore be able to collect in the lower region of the suction-material container 2, so that there is a large reservoir for separated liquid available. If the user turns the device or operates it upside down, this liquid can also be taken up in the suction container 2, without the risk of the liquid level coming close to the inlet opening of the suction channel 4. The greater danger is that the liquid gets into motion and in this way separated again by waves or splashing parts of the liquid and could be sucked in from the suction channel 4.
the Schwapptik invention 6 is preferably made of an elastic material, so that it can take over an additional damping functions by its mobility. Furthermore, the Schwapptik 6 is preferably designed so that along its edges liquid can flow even when standing upside down device forward, the Schwapptik 6 should therefore not be a definitive flow brake.
FIGS. 4 and 5 show a first embodiment of the Schwapptikes 6, wherein the FIG. 5 the back of the in FIG. 4 shown Schwapptik6 reproduces.
a centering aid 7 is provided, which is designed as a projecting block and with a corresponding recess in the suction channel 4 together.
a NutfederNK or any other form fit can be used.
the slosh guard 6 essentially only covers the upper region of the suction material container 2. In the lower region, only an annular region is provided, which leaves the majority of the cross section open and only serves for fastening the squeeze protection 6 to the tubular suction channel 4.
the illustrated Schwapptik 6 has at its upper corners respectively recesses, which are due to the fact that the suction container 2 is shaped accordingly in this area, so that the edge of the Schwapptikes 6 is adapted to the inner contour of the suction container 2. In addition, however, these corners are formed slightly larger, so that sufficient space between the inner wall of the suction container 2 and the edge regions of the Schwappsches 6 remains, so that liquid can flow even with upside down device from back to front or from front to back.
FIG. 6 a further embodiment of the Schwapptikes 6 is shown as essentially the embodiment of the FIGS. 4 and 5 equivalent.
this embodiment has a reinforcement in the form of a sleeve 9 in the middle region.
the lower edge region which is located substantially in the region of the center plane of the suction container 2, is here provided with protruding forward and rear heels, such as a free drooping of drops, which could then fall arbitrarily and be sucked prevent.
FIGS. 7 and 8 Embodiments of the Schwapptikes 6 are shown again.
the FIG. 7 variant shown corresponds to that of the FIGS. 4 and 5
the FIG. 8 variant shown additionally has a lower edge, which is curved outwards, so that there is a downward sloping edge line, which has the particular advantage that this drops, which could result from running liquid, run to the outside, so that they be deflected from the suction channel 4 and then run on the outer wall of the suction container 2.
