Definitions

such a suction device has a housing shell having a lower longitudinal side, a housing cover fastened to the housing shell and a Abziehlippe which is held in a running between the housing shell and the housing cover groove in the lower longitudinal side and with a peel edge of the housing shell extends to the outside and extends along the lower longitudinal side.
the suction nozzle further has in a region remote from the Abziehlippe a connection region for connection to a suction channel of the portable device and in the Abziehlippe one with the connection area in fluid communication with the intake gap, can be sucked through the suction material collecting before the Abziehlippe.
a suction nozzle of this kind is from the EP2638839 A1 known. Such suction nozzles are used in conjunction with hand-held devices for sucking up liquids. In this case, the liquid can be absorbed both by a vertical or inclined surface and by a flat surface, such as a table or a floor.
the suction nozzles are connected to a portable suction device via a nozzle.
the suction nozzles In the front region, the suction nozzles have a suction mouth, which is formed by the Abziehlippe and a parallel thereto arranged suction lip, wherein between the Abziehlippe and the suction lip, the actual suction gap.
the suction lip is not applied by the suction pressure to the Abziehlippe and thus closes the suction mouth are usually small spacers in the form of surveys provided that keep the Abziehlippe and the suction lip to a minimum distance.
the Abziehlippe usually extends over the entire width of the suction nozzle. It is elastically formed and arranged in the withdrawal direction behind the suction lip, wherein the suction lip usually has smaller gaps to allow the liquid through even when the user angled the suction nozzle so that the suction lip is in turn long moved to the surface to be deducted with contact to this ,
the Abziehlippe is moved along the surface and can thereby wear out.
the lancing lip must be small enough to fit between the individual rungs of the window.
the same user may also wish to have a larger working width for cleaning larger surfaces by means of a correspondingly longer larger draw-off lip.
the object of the invention is therefore to provide a suction nozzle which allows a secure hold and a simple exchange possibility of Abziehlippe.
the suction nozzle according to the invention now has a Abziehlippenage, in which at least one clamping means is arranged, which projects into the Abziehlippenam such that it is able to press the Abziehlippe against a wall of the Abziehlippenfact under application of a clamping force.
the Abziehlippe can now be easily replaced.
the clamping means can be released, so that the Abziehlippe can be pulled laterally from the Abziehlippenfact.
This allows for a easy replacement of a damaged Abziehlippe or replacing a too large Abziehlippe by a smaller Abziehlippe.
the smaller Abziehlippe can be designed so that it protrudes with a central region down, as is the case with the larger Abziehlippe.
pure closure areas can connect, which close the gap between the housing cover and the housing shell, in order to deactivate the suction function in the unneeded area.
the clamping means is formed by a pressure piece, which may be formed as a mandrel or rib and protrudes into the Abziehlippenam.
This pressure piece fixes the upper part of the Abziehlippe having substantially the same shape as the Abziehlippenfact, so that this upper part of the Abziehlippe can be easily inserted into the Abziehlippenfact.
the Abziehlippe this can additionally have a kink-resistant thrust element, for example in the form of a running along the upper edge of the Abziehlippe rod.
the Abziehlippe may be held in a U-shaped holder which is inserted into the Abziehlippenfact. In the latter two cases, the pressure piece can act either directly on the Abziehlippe or on the pusher or the U-shaped holder.
the housing shell of the suction nozzle in a preferred embodiment of the invention, an open or closed channel, which can be connected via the connection piece with the intake port of a portable suction device.
an open channel this is then closed by placing the housing cover, so that the negative pressure between Abziehlippe and suction lip can be applied.
the closed channel widens to a running between the Abziehlippe and the suction lip gap.
the clamping means is arranged either on the housing shell or the housing cover.
the clamping region of this clamping means projects into the Abziehlippenam, wherein the Abziehlippenam between the housing shell and the housing cover is trained.
one of the two components or both components, namely housing shell and housing cover a groove which forms the Abziehlippenage after assembly of the two components. This means that for mounting the Abziehlippe this is inserted into one of the two components and then fixed by fastening the other component, the Abziehlippe in Abziehlippenfact.
the clamping means can of course also be arranged on the Abziehlippe itself.
the Abziehlippe have thickenings which are compressed in the Abziehlippenfact and generate the clamping force.
the clamping force applied by the clamping means is spatially directed so that it is oriented in the direction in which the Abziehlippenfact is increased. Usually this will be a direction perpendicular to the longitudinal extension of the Abziehlippe, which is also the release direction in which the housing cover can be removed from the housing shell at the same time.
a further preferred embodiment of the invention has an actuating means which either has the clamping means at its end or via which the clamping means against the Abziehlippe can be adjusted.
the adjusting means may be a simple screw which is screwed into the housing cover or the housing shell and with its front end after screwing on the Abziehlippe this firmly clamped.
the clamping means may for example be movably mounted in the housing shell or the housing cover, wherein the adjusting means can then be screwed or pushed into this storage area, so that the adjusting means is able to displace the clamping means in the direction of the Abziehlippe.
the adjusting means can be a normal screw, alternatively thumbscrews or thumbscrews can be used here. Also, it is not necessary that this screw is screwed with multiple turns within its thread, the only important thing is the fact that a corresponding path length the front end of the actuating means is provided so that the necessary clamping force can be applied to the clamping means.
At least two adjusting means are used with which the housing cover is fixed on the housing shell.
the housing cover can be formed, for example, by two laterally covering areas, which are screwed onto a closed suction channel having housing shell and thus fix the Abziehlippe in the side region of the suction nozzle. These screws can also be passed through through openings in the suction lip at the same time, so that they simultaneously hold the suction lip on the housing shell or the housing cover. This suction lip can then be spatially fixed by screwing the housing shell with the housing cover, in which the upper part of the suction lip is clamped between the two components.
the Abziehlippenfact is preferably designed in the suction nozzles according to the invention so that it has at least in the region of the clamping means of a negative mold the shape of the Abziehlippe in the strained area.
a certain amount of play can occur, so that the Abziehlippe can easily be pushed back and forth in the Abziehlippenfact. This ultimately depends on the material of the Abziehlippe, especially soft materials will require a larger game so that the Abziehlippe can be inserted without risk of buckling from the side into the suction nozzle, without the housing cover would have to be completely removed from the housing shell.
FIG. 1 a suction nozzle according to the invention is shown.
the FIGS. 2 and 4 show this suction nozzle in a three-dimensional view and in a sectional view.
FIG. 3 is the detail "B" off FIG. 2 reproduced in an enlarged view.
the housing cover 1 is formed so that has two side wings, which are arranged on the two sides of the suction nozzle.
the housing cover 1 is mounted on the housing shell 2 and forms together with the housing shell 2 on both sides of a part of the Abziehlippenage. 6
the housing shell 2 is provided with a semi-cylindrical recess, at the upper, front edge of the clamping means 5 is provided in the form of a rib. As in FIG. 4 shown, this clamping means 5 presses into the upper, hidden area of the rubber-elastic Abziehlippe 3.
the parts of the housing cover 1 are screwed to the housing shell 2, wherein the screws are not visible here.
the screw is released, so that the housing cover 1 is loosened relative to the housing shell 2 and the Abziehlippe 3 can be pulled laterally out of the suction nozzle.
FIG. 5 An adjusting means 10 is provided, which is screwed into the housing shell 2, so that the clamping means 5 can be employed via adjusting means 10 against the upper, hidden area of the Abziehlippe 3.
adjusting means 10 forming screw.
a hexagon screw is shown, alternatively, a wing nut or other screw can be used, the user can easily grasp and solve.
all other forms of snaps or similar configurations may constitute the actuator 10.
