Hand held suction device

The invention relates to a hand-held suction device, comprising a housing device, a suction fan device for generating a suction flow, which is arranged in a housing of the housing device, a suction container, which has an interior, which with the

Suction of the Sauggebläseeinrichtung can be acted upon, a holder for a battery device, a handle, and a suction connection piece, which is arranged on the suction material container.

From WO 2008/009883 AI a hand-held cleaning device is known, which has a handle with a first end and a second end, wherein an air flow generator is disposed directly adjacent to the first end of the handle and a power source adjacent to the second end of the handle is arranged ,

From WO 2008/009888 AI a hand-held cleaning device is also known.

From US 5,970,572 a battery-powered hand-held vacuum cleaner is known.

From GB 2 276 311 A a hand-held vacuum cleaner is known.

From WO 2008/065313 A2 a suction and cleaning device is known, which has a nozzle, a tank for clean water, an air-water separator, and a tank for receiving dirty liquid and / or dirt. There is a handle provided. Furthermore, heating means are provided.

The invention has for its object to provide a hand-held suction device of the type mentioned, which has extended uses. This object is achieved in the above-mentioned hand-held suction device according to the invention in that a pivot bearing is provided, via which the suction connection piece is rotatable to the interior of the suction material container.

By a rotation of the suction connection piece relative to the interior of the suction material container and thereby also to the housing device in a suction operation, the housing device can be, for example, reposition relative to a suction nozzle, which is connected to the suction connection. This makes it possible to achieve an arrangement of the housing device which is optimized for a cleaning operation in tight spaces.

In particular, an axis of rotation of the pivot bearing is oriented at an acute angle to a handle axis and / or is oriented at an acute angle to a Sauggutbehälterachse and / or is oriented at an acute angle to an insertion and removal device of a battery device to the holder for the battery device. This results in optimized alignment of the suction connection piece and extended cleaning options.

It is advantageous if the suction connection piece has a first region and a second region, wherein the suction connection piece is mounted on the first bearing on the rotary bearing and wherein the second region is positioned on an outer side of the suction material container. It can thereby position the second area in different positions relative to the housing device. There are extended cleaning options.

In particular, the second region is designed such that a suction nozzle and / or a suction hose and / or a suction pipe can be connected to it. As a result, the suction nozzle or the suction hose or the suction pipe can be repositioned relative to the housing device via the rotary bearing, if this is necessary. In one embodiment, a first axis of the first region and a second axis of the second region are at an angle to each other, which is in particular between 120 ° and 150 ° and in particular is 135 °. The first axis and the second axis are, in particular, center axes or axes of symmetry of the first area and of the second area. The first region and the second region are in particular tube regions. It is then formed a pipe angle. It can thereby be varied in a simple manner, a rotational position of the second region to the housing device. The first area, which is the coupling of a suction flow with suction material in the

Interior determined, is not repositioned with respect to the flow coupling. (A rotation of the first region of the rotary bearing does not change the flow guide.) It is advantageous if a suction connection opening is arranged at the first region, which opens into an intake space of the suction material container. As a result of this design of the suction connection piece and its arrangement on the rotary bearing, the flow guidance during the coupling into the suction space is independent of the rotational position of the suction connection piece. The second region of the Sauganschlussstutzens but is variable in its rotational position to the housing device.

It is favorable if an interior of the suction material container of the suction connection opening opposite a wall is arranged. This wall forms a baffle wall. It ensures a flow deflection. This results in an optimized coupling. Furthermore, the wall can be formed as a protective wall or demarcation wall for a receiving space for a filter device. As a result, in turn, a flow deflection from the suction space into a coupling space for the filter device can be achieved in a simple manner. By the flow deflection can be realized again in a simple manner, a separator in the interior of the suction container. In particular, the wall is oriented at an acute angle to a first axis of the first region, wherein in particular the acute angle is in a range between 30 ° and 60 ° and in particular at 45 °. In particular, the acute angle is the supplementary angle of the angle between the first axis of the first region and the second axis of the second region to a 180 ° angle. A flow deflection can be achieved by which, for example, a precipitator effect can be realized in a simple manner. Furthermore, it is thereby possible to supply suction material to a flow-calming zone in the interior of the suction-material container in a simple manner.

In one embodiment, the suction material container has a wall for holding the rotary bearing, which is oriented at an acute angle to the wall in the interior of the suction material container. This results in an optimized flow guidance.

It is advantageous if the suction connection piece is assigned a fallback flap arranged in an interior of the suction material container. In a suction operation with appropriate negative pressure, the fallback flap is open. In a non-suction mode, it is closed. This prevents suction material from falling out of the sump container via the suction connection piece.

Advantageously, the pivot bearing is associated with a locking device by which a certain rotational position of the Sauganschlussstutzens relative to the suction material container (or the housing device) is detectably adjustable. This results in a comfortable operation.

In one embodiment, the locking device comprises at least one actuating element for releasing a detected rotational position, which is associated with the suction connection piece. It is in particular rotatable with the suction connection piece. By means of this actuating element, a determined rotational position can be achieved by a single-handed operation by an operator become. The operator can then perform a rotation without the need for embracing it.

For example, the locking device has at least one latching element and at least one latching counter element, wherein by cooperation of a latching element with a latching counter element a certain rotational position can be determined in particular by positive locking. This results in a simple way a statement about locking. This can be solved easily.

It is constructively favorable if the at least one latching element is spring-loaded, wherein a spring force must be overcome in order to release the at least one latching element from a latching counter-element. This results in particular an automatic locking, when a locking element is aligned cooperating with a corresponding locking counter-element.

In a structurally favorable embodiment, a plurality of locking counter-elements are arranged on a body of the suction container, relative to which the suction connection piece is rotatable, and at least one locking element is associated with the suction connection piece. An operator can, for example, perform a rotation relative to the body of the suction material container via a gripping ring, which is non-rotatably connected to the suction connection piece. The actuating element acts in particular on the latching element. With the same hand, which performs the rotation, then the operator can also solve a finding, without encroachment is necessary.

The suction device is battery powered in one embodiment. It can be provided that the suction container is supported at the bottom of a holder for the battery device. By supporting the suction container down on the holder results in a mechanically stable and compact design of the hand-held suction device. The holder can be configured independently of the suction container for holding the battery device. In particular, it is thereby possible in a simple manner to remove the battery device from the holder for the battery device or to insert the battery device, even if the suction material container is arranged on the housing device.

Furthermore, a Sauggebläsebehälter can be realized, which has a relatively large intake volume for suction material. The result is a compact design, when the suction container is supported on a bottom down against the holder for the battery device. In particular, a battery device can thus be removed from the holder to the front or inserted in the opposite direction. The suction container is "not in the way". This makes it easy to integrate a detachable battery device on the hand-held suction device. This makes it possible, for example, to obtain long operating times by using a plurality of battery devices and in particular rechargeable battery devices. Furthermore, thereby the electrical energy supply to the Sauggebläseeinrichtung be optimized. For example, a region of the holder which is remote from the suction material container (if it is fixed to the housing device) can then be used for positioning electrical connection contacts. As a result, in turn, electrical connecting lines can be easily guided through the handle to the suction fan device.

In particular, the handle between the housing device and the holder for the battery device is arranged at a distance from the suction material container. This results in a simple operation. The center of gravity of the suction device can be arranged in such a way that an optimized operability and in particular one-hand operability for a suction operation results.

It is favorable if the handle is connected to the holder for the battery device or to an element arranged on the holder and / or is connected to the housing device. This results in a simple operation in a compact design.

It is also advantageous if electrical connection lines lead from the holder for the battery device through the handle to the suction fan device. As a result, the conduction path can be kept low. This results in a simple manufacturability of the suction device.

It is particularly advantageous if the holder for the battery device is assigned an insertion direction and removal direction for a battery device which are oriented transversely to a handle axis and / or transversely to a suction container axis. It can thereby realize a compact suction device. The battery device can also be removed or used when the suction material container is arranged on the housing device.

Conveniently, a suction connection opening and / or a suction connection piece are arranged on the suction material container. This results in a compact structure. It is advantageous if a support surface for the suction material container is formed on the holder for the battery device. This support surface forms a counter surface for the support of the suction material container to the holder.

It is particularly advantageous if a guide device for positioning the suction material container on the holder for the battery device is arranged on the holder for the battery device and / or that a guide means for positioning the suction container on the holder for the battery device is arranged on the suction container , By means of the corresponding guide device, a guide including centering of the suction material container in relation to the housing device can be obtained. This results in a simplified insertion of the suction material container on the housing device or a simplified removal. It is particularly advantageous if a pivot bearing is provided for the suction material container, by means of which the suction material container can be pivoted relative to the housing device at least in a specific pivoting range. This results in a simple usability or removability, especially in one-handed operation for the suction material container. For example, a hand holding the suction device to the handle. With the other hand then the suction container can be used or removed. In particular, can be used as a first step for the insertion hooking on the pivot bearing cause or as a last step in the removal of the suction container of the housing means is a hook on the pivot bearing.

It is advantageous if the pivot bearing is designed so that upon reaching a certain pivot position of the suction material container away from the housing means of the suction material container in the region of the pivot bearing of the housing device is releasable. This results in easy operability and, in particular, single-handed operability with regard to the removal of the suction material container or with respect to the insertion of the suction material container. In one embodiment, the pivot bearing has at least one immersion recess and at least one immersion element for the at least one immersion recess, wherein (i) an immersion element is arranged on the housing device and an associated immersion recess is arranged on the suction material container and / or (ii) an immersion element on the Suction container and an associated immersion recess is arranged on the housing device, and wherein a submerged element and the associated immersion recess are adapted to each other so that in a certain position range of the suction container to the housing means immersed in an immersion immersion element of the suction container to the housing means is pivotable, and that in a further specific position range of the immersion element from the associated immersion recess is replaceable in order to remove the suction material container from the housing means can. It is through formed via the immersion recess and the immersion a swivel bearing, which allows in a certain position range of the suction container to the housing means a pivoting and in the other position range allows a decrease. This is possible via a one-hand operation (holding the suction container with one hand and holding the rest of the suction device with the other hand). In particular, can then be done on the pivot bearing in a simple manner when inserting a suction container and a hooking on the housing device. To remove a suction container pivoting can take place and after reaching a certain pivot position unhooking.

In particular, a suction material container part of the pivot bearing is arranged on an end of the suction material container facing away from a bottom side of the suction material container, and a housing device part of the pivot bearing is arranged on an end of the housing device facing away from the holder for the battery device. This results in a compact design with ease of use with respect to the removal of the suction material container or the insertion of the suction material container. It can be carried out at the removal of a swing away from the housing device to the holder. When inserting, it is possible to turn the housing device onto the holder.

The housing device part of the pivot bearing is protected when it is disposed on the inside of a housing device flange. The swivel bearing can thereby be formed in a structurally simple manner.

It is also advantageous if a locking device is provided for releasably locking the suction material container with the housing device. This makes it possible in a simple way to fix and lock the suction material container with respect to the housing device. It can be achieved in a simple manner that an air-tight flow path for Saugstromaufschlagung the interior of the suction material container is reached. In particular, a housing device part of the locking device is arranged on the housing device spaced from the holder for the battery device and is in particular arranged at a distance from a pivot bearing for the suction material container. This makes it possible to realize a connection of the suction container to the housing device and the holder at several points in order to achieve an optimized fixation and in particular airtight flow guidance. The suction container can be easily removed and used. For the same reason, it is favorable if the housing device part of the locking device is positioned adjacent to the handle and in particular adjacent to a switch arranged on the handle.

It can be provided that the locking device is associated with a guide device for guiding the suction material container on the housing device. Then, when the suction container is in a certain position range to the housing means, then the guide means can be effective and provide for a pre-positioning or centering. This results in a simplified applicability and possibly also removability.

It is advantageous if the locking device has at least one actuating element which is arranged on the suction material container, wherein the locking device is arranged and designed so that the at least one actuating element can be actuated with the same hand, which the suction material container during removal of the suction material container from the housing device holds. It can be removed or used by a suction container with a single hand. (The other hand, for example, holds the suction device by the handle.)

It is advantageous if the locking device has actuating elements arranged on opposite sides of the suction material container. The suction container can be held by a hand without grasping. decision speaking fingertips, for example, of the thumb and forefinger may then act on the actuators to release a lock. It is particularly advantageous if the housing device comprises a web element which is arranged between the holder for the battery device and the housing spaced from the handle and is supported on the holder and directly or indirectly on the housing. This results in a stable structure. The housing device is then connected to the holder both via the handle and via the web element. For example, elements of a locking device can also be arranged on the web element. It can thereby achieve a fixation area for the fixation (locking) of the suction material container to the housing device and the holder at different locations.

It is favorable if the web element is connected to the holder for the battery device and is connected to the housing or to a region connected to the housing. This results in a stable mechanical structure of the suction device.

It is also advantageous if a locking device for the suction material container for fixing the suction material container to the housing device is arranged at least partially on the web element. This results in a mechanically stable fixability of the suction container to the remaining suction device, the suction container is in a simple manner (especially one-handed operation) can be removed or used. It can be achieved in a simple manner, an airtight connection between the suction material container and the housing device with respect to a suction flow. It is particularly advantageous if the web element is connected to an intermediate region of the housing device which is connected to the handle and over which the handle is spaced from the housing and thereby to the suction fan device. The intermediate area, which is particularly solid, is located between the suction fan (which is arranged on the housing) and the handle. At the intermediate region, in which in particular integrally sits the web element, the web element is fixed. At the web element, for example, a shoulder can also be formed as a contact surface, in particular for a downward support for the suction material container.

It can be provided that a filter device for the suction fan device is arranged detachably on the suction material container. This makes it possible, for example, to clean a removed suction material container in a simple manner.

It is advantageous if a stop for the filter device is arranged on the housing device. As a result, the filter device can be clamped in a simple manner in the event of a locked positioning of the suction material container on the housing device.

It can be provided that a wall is arranged in an interior space of the suction material container opposite a suction connection opening. The wall forms a baffle for suction material. It also forms, in particular, a protective wall for a filter device. Due to the impact effect of the wall, a flow umienkung can be achieved. In this way, it is possible, in particular, to supply suction material to a flow-calming zone in a simple manner, and it is possible to achieve a flow rate reduction so as to realize a separator for the separation of solid suction material from an airflow.

It is advantageous if the wall separates an intake space of the suction material container and a receiving space for a filter device, wherein in particular the filter device is removable. It can thereby realize a flow guidance, which has a separator effect. Furthermore, a flow-calming zone for suction material can be realized in a simple manner. Advantageously, the wall provides a contact surface for the filter device. This results in a compact construction of the suction material container.

It is also advantageous if the wall has at least one opening and / or the wall is associated with at least one opening which is located between the Einsaugraum and a receiving space for the filter device. It can thereby achieve a flow deflection, to guide a suction flow. In turn, the flow deflection can be achieved in a simple manner, a deposition effect.

It is favorable when the wall forms or provides a flow deflection region, at which a suction flow in an intake space of the suction material container can be deflected to a supply flow to a filter device.

This makes it easy to achieve a separator effect. Furthermore, a flow rest zone can be formed in a simple manner on the suction material container. Furthermore, it is possible to provide a large receiving volume for suction material for the suction material container.

In particular, the flow deflection region on the suction material container is at a height relative to an underside of the suction material container, which is at least approximately equal to or greater than a height of the handle via an upper side of the holder for the battery device. This results in a compact construction of the suction device and the suction material container. The suction container can be realized with a high absorption volume for suction material.

It can be provided that the suction container has a flow rest area in its interior, which adjoins in particular to an underside of the suction container. This results in a high absorption volume for suction material in the suction container with a compact construction of the suction device. A Aufwirbelungseffekt for collected waste material is minimized. In particular, based on a main flow direction for the introduction of suction material in the flow rest region is an intake, in which a suction port opens, and a Strömungsumlenkbereich in which a flow is deflected to a filter device, above the flow rest region. This results in a compact construction of the suction material container and thus of the suction device. It is possible to achieve a high absorption volume for suction material in the suction material container with a compact construction of the suction device. In one embodiment, a holder for accessories is provided, which is arranged on an upper side of the housing device. As a result, accessories can be stored to save space. For example, the holder is formed as a clip, through which an elastic force in the direction of the top of the housing device is exercisable. As a result, for example, a suction nozzle can be clamped to the top of the housing device.

It can further be provided that connections are arranged in particular for a carrying strap on the housing device and / or the holder and / or the handle. If the suction device is provided with the carrying strap, a long suction operation can be carried out fatigue-free.

An exemplary embodiment of a hand-held suction device according to the invention, which is shown in FIGS. 1, 3, 5, 6 to 8, 11, 13, 15, 17 to 19 and designated therein by 20, comprises a housing device 22 with a housing 24 , which is part of the housing means 22, receives a suction fan 26. The suction blower device 26 disposed in the housing 24 includes a blower motor and a blower.

For example, ventilation slots 28 for the fan motor of the suction fan device 26 are arranged on the housing 24.

The blower motor is an electric motor. For the electrical power supply of the fan motor, a battery device 30 is provided, which is in particular a rechargeable battery device.

The battery device 30 is arranged on a holder 32 and arranged in particular detachably. The holder 32 is spaced apart in a height direction 34 from the housing 24 or the suction fan device 26.

For holding the suction device 20, a handle 36 is provided. The handle 36 is connected to the holder 32 and the housing device 22. He extends along a handle axis 38, to which it is aligned substantially parallel, from an upper side of the holder 32 to an intermediate portion 40 of the housing means 22. The intermediate portion 40 is connected to the housing 24 and connected to the handle 36. It lies outside of the suction blower device 26 or outside the region of the housing 24, which receives the suction blower device 26, so that the handle 36 is at an upper end spaced from the suction blower device 26. The intermediate region 40 of the housing device 22 serves inter alia to provide a mechanically stable connection of the housing device 22 outside the housing 24 to the web element 46, so that it is stably connected to the housing device 22 and in particular is integrally connected to the intermediate region 40. This in turn allows a high mechanical stability of the suction device 20 can be achieved.

The handle 36 may also be connected directly to the housing 24 without an intermediate region 40. On the handle 36, a switch 42 is arranged, which is in particular positioned so that when the handle 36 is held with one hand, it is operable with the index finger. By the switch 42, the suction operation of the hand-held suction device 20 can be turned on or off. In one embodiment, a suction program, in particular with regard to the power of the suction fan device 26, can also be set via the switch 42.

The switch 42 is positioned at a small distance (which is in particular less than 5 cm) to a lower side of the intermediate region 40, the underside of the intermediate region 40 facing an upper side 44 of the holder 32. In one embodiment, the top 44 of the holder 32 for the battery device 30 is oriented substantially perpendicular to the height direction 34. The handle axis 38 lies at an acute angle, which is in particular in the range between 60 ° and 80 °, to this top 44th

(The supplementary angle to 90 ° corresponds to the acute angle between the height direction 34 and the handle axis 38.)

The handle 36 is at least approximately straight. External tangential planes on the handle 36 are at least approximately parallel to the handle axis 38.

Along the handle axis 38, the handle 36 has its longest extent. The housing device 22 is connected to the holder 32 at its upper side 44 via a web element 46. In this case, the web element 46 is connected in particular to the housing 24 at a distance from the intermediate region 40.

The holder 32 is thereby connected to the housing device 22 both via the web element 46 and via the handle 36.

Between the web member 46 and the handle 36, a free space 48 is formed. Through this space fingers of a holding hand, which holds the suction device 20 to the handle 36, dive through. As mentioned above, the switch 42 can be operated, for example, via the index finger.

The holder 32 has a longitudinal extent in a holder axis 50. The holder 32 has, relative to the holder axis 50, a first end 52 and an opposite second end 54. The web element 46 is connected to the holder 32 in the region of the first end 52. The handle 36 is connected to the holder 32 in the region of the second end 54. From the holder 32 lead electrical connection lines 56 (see Figure 19) to the suction fan 26 through the handle 36 therethrough. These are guided through the intermediate region 40 to the housing 24. The switch 42 is coupled to this electrical connection.

The particular rechargeable battery device can be removed from the holder 32 in a removal direction 58a or can be inserted on the holder 32 in an anti-parallel insertion direction 58b.

In particular, a slide-in guide is provided on the holder 32, and a releasable detent mechanism for locking the battery device 30 to the holder 32 is provided. The removal direction 58a and the insertion device 58b are transversely and in particular perpendicular to the height direction 34. They are oriented transversely to the handle axis 38 and in particular oriented at an acute angle to the handle axis 38. In one embodiment, this acute angle corresponds to the acute angle of orientation of the top 44 to the handle axis 38.

In particular, the removal direction 58 a and the insertion direction 58 b are parallel to the holder axis 50.

The holder 32 has at the second end 54 on a transverse region 60. This transverse region 60 covers the battery device 30 in the direction of the holder axis 50 at the second end 54. An electrical contact strip for the electrical battery device 30 can be arranged on it, to which the electrical connection lines 56 are connected.

In one embodiment (see FIG. 19), the contact strip (denoted by reference numeral 314 in FIG. 19) is outside the transverse region 60 disposed on one side opposite the top 44 on the holder 32.

The suction fan means 26 has a suction fan axis 62 which is substantially coaxial with a rotational axis of a turbine wheel, or coaxial with or parallel to a motor axis of the fan motor. The housing 24 extends in the Sauggebläseachse 62nd

The suction fan axis 62 lies transversely to the height direction 34 and in particular perpendicular to it.

The housing 24 extends in the suction fan axis 62 from a first end 64 to an opposite second end 66. The handle 36 is accordingly oriented with its handle axis 38 at an acute angle to the suction fan axis 62. (This acute angle is the counter angle to a 180 ° angle to the acute angle between the top 44 and the holder axis 50 and the handle axis 38.) Relative to the height direction 34 is the second end 66 of the housing 24 (which also has an end the housing means 22 in the suction fan axis 62) is at least approximately in alignment with the second end 54 of the holder 32 at the transverse region 60 and thus with a lower end of the handle 36; an envelope plane for the housing means 22 at the second end 66 and the holder 32 at the second end 54 is oriented parallel to the height direction 34. It is oriented in particular perpendicular to the upper side 44.

Between an attachment region 68 of the handle 36 to the intermediate region 40 and the second end 66, the housing device 22 is optionally angled outwardly with a curvature, so that a continuous outer contour of the housing device 22 between the handle 36 and the housing 24 results. The housing device 22 has, as it were, a constriction at the intermediate region 40. This constriction is preferably outside the housing 24, which receives the Sauggebläseeinrichtung 26.

At the first end 64, the housing device 22 has a flange 70 (FIG. 2). This will be explained in more detail below.

At the first end 64, the housing means 22 is formed straight as a combination of the housing 24 and the intermediate portion 40. A corresponding envelope plane 72 is parallel to the height direction 34. The envelope plane 72 strikes the ridge element 46 (compare, for example, FIG. 8). On the housing device 22, a shoulder 76 is formed at a connecting region 74 of the support element 46 with the housing device 22 at its first end 64 (compare, for example, FIG. 5). This shoulder 76 provides a contact surface 78 which is oriented at least approximately parallel to the upper side 44 or at least approximately perpendicular to the height direction 34.

The hand-held suction device 20 comprises a suction material container 80, which is detachably fixed to the housing device 22 and / or the holder 32.

The suction container 80 has an outer wall 82, which defines an inner space 84. When arranged on the housing means 22 suction material container 80, the interior 84 of the suction container 80 can be acted upon by a suction flow generated by the suction fan 26.

The suction material container 80 has a first region 86. At the first region 86, a suction connection piece 88 is arranged. The suction connection stub 88 has a suction port 90, which opens into the interior 94 (Figure 3).

The suction connection opening 90 is formed at a first region 92 of the suction connection piece 88. The suction connection piece 88 further has a second region 94 which is connected to the first region 92 and in particular is integrally connected. The second region 94 has an opening 96, which is fluid-effectively connected to the suction port 90. Suction, which flows through the opening 96, flows to the suction port 90 and from there into the interior 84 of the suction container 80th

The second region 94 of the Sauganschlussstutzens 88 is positioned on an outer side of the Entaugtutbehälters 80. For example, a suction nozzle can be connected to the second region 94 with the opening 96 and / or a suction pipe can be connected and / or a suction hose can be connected.

In principle, it is also possible to suck in suction material directly via the second region 94 at the opening 96.

The suction connection piece 88 is formed in one embodiment as a pipe angle.

The first region of the suction connection piece 90 has a first axis 98 (FIG. 3). The first axis 98 is a central axis of the corresponding pipe region and in particular an axis of symmetry. The second region 94 has a second axis 100, which is a central axis of the corresponding tube region, and in particular an axis of symmetry. The first axis 98 and the second axis 100 are at an angle 102 to each other, which is an obtuse angle in the range between, for example, 120 ° and 150 ° and in particular at about 145 °. When the suction material container 80 is arranged on the housing device 22 and is thereby fixed, the first axis 98 lies at a fixed angle to the handle axis 38 or the height direction 34 or the holder axis 50. An angle between the first axis 98 of the suction connection piece 88 and the height direction 34 corresponds to the supplementary angle of the angle 102 to a 180 ° angle.

As explained in more detail below, the position of the second axis 100 of the Sauganschlussstutzens 88 relative to the height direction 34 (or the handle axis 38 and the holder axis 50) vary.

The outer wall 82 of the suction material container 80 comprises a wall region 104. This wall region 104 forms a wall for holding a rotary bearing 106 on a body of the suction material container 80.

The wall region 104 (the retaining wall for the rotary bearing 106) is oriented transversely and in particular perpendicular to the first region 92 (with respect to its first axis 98) of the suction connection piece 88. It is accordingly oriented with respect to the height direction 34 when the suction material container 80 is arranged on the housing device 22, at an acute angle. This acute angle corresponds in terms of the supplementary angle of the angle 102 to a 180 ° angle.

The wall region 104 is formed in one embodiment as a lid, which is detachably mounted on the outer wall 82. The wall portion 104 with its design as a cover can be removed in particular including the pivot bearing 106 with the suction connection piece 88 in order to be able to empty the suction material container 80 and, if necessary, be able to clean it.

In the embodiment shown, the first region 92 to the second region 94 is in the angle 102 of about 135 °. Accordingly, the acute angle between the wall portion 104 and the height direction 34 about 45 °.

The pivot bearing 106 has an axis of rotation 108 which is coaxial with the first axis 98 of the first region 92. Accordingly, the axis of rotation 108 is oriented at arranged on the housing means 22 suction material container 80 at an acute angle to the height direction 34.

The rotary bearing 106 comprises a bearing body 110 (FIG. 4), which is rotationally fixedly positioned on the wall region 104 outside of the inner space 84 and thus non-rotatably connected to the body of the suction material container 80. In the bearing body 110, the suction connection piece 88 is mounted via a counter region 112, in particular via a sliding guide. In one embodiment, the mating portion 112 is spaced from the first portion 92, that is, that portion of the pivot bearing 106 that is rotationally connected to the suction port 88 has a greater width than the first portion 92 and thus as the suction port 90. As a result, a corresponding large storage area is provided.

To determine certain rotational positions, the pivot bearing 106 has a locking device 114. It is basically possible that the rotational positions are infinitely adjustable. In the embodiment shown, the detent 114 provides a plurality of defined discrete lockable rotational positions.

The bearing body 110 surrounds the opposite region 112 of the Sauganschluss- stutzens 88th

The counter region 112 is assigned a latching element 116. The locking element 116 is connected to the suction connection piece 88 on the pivot bearing 106 about the rotary axle 108 rotatable. On the bearing body 110 spaced locking detent elements 118 are arranged on a ring spaced.

In one embodiment, a latching element 116 includes a latching lug 120 (FIG. 4). A locking counter-element 118 is a recess 122 which is adapted to the latching nose and into which the corresponding latching nose 120 can dip.

If a detent 120 is immersed in a recess, then a positive locking against rotation is achieved. By dipping the locking lug 120 by an associated recess 122 as a counter-locking element 118, the rotation can be released (see Figure 4).

The locking element 116 is spring-loaded. For this purpose, a spring device 124 is provided. The spring device 124 comprises in particular a compression spring 126.

The locking device 114 comprises an actuating element 128 which is designed in particular as an actuating switch. The actuating element 128 is supported via the spring device 124 (via the compression spring 126) on a transverse wall 130. The transverse wall 130 is oriented transversely and in particular perpendicular to the wall region 104. The transverse wall 130 is a part of the opposite region 112 of the pivot bearing 106. On the actuating element 128, the latching lug 120 of the latching element 116 is arranged. When the latching lug 120 is positioned above a recess 122, the spring device 124 pushes this latching lug 120 into the recess 122. By exerting a force in one direction 132 (FIG. 4) on the actuating element 128, the spring device can be overcome by overcoming the spring force 124 dive the latch 120 from the associated recess 122. As a result, the positive connection between the counter area 112 and the bearing body 110 is released and the suction connection piece 88 can be rotated relative to the interior 84 of the suction container 80 at the suction container 80.

If, for example, after the removal of a corresponding latching lug 120 from the recess 122 (by pressing the actuator 128) is rotated and the actuator 128 is released, then the detent latches 120 due to the force of the spring means 124 in the next reached recess 122 a. In one embodiment, only a single actuator 128 and correspondingly only a single latching element 116 is provided.

In particular, a gripping ring 134 is arranged on the suction connection piece 88 on the opposite region 112. On the grip ring 134, the actuator 128 is arranged. By the handle ring 134, an operator can act in an ergonomic manner on the suction port 88 to rotate it in the pivot bearing 106 about the axis of rotation 108 relative to the body of the suction container and to achieve a determination by the locking device 114 in the desired position.

In FIGS. 13 (with associated FIG. 14), 15 (with associated FIG. 16) and FIGS. 17, 18, different rotational positions of the suction connecting piece 28 are relative to the interior 84 of the suction container 80 or relative to the handle 38 and relative, respectively shown to the wall portion 104, that is relative to the body of the suction container 80th

This results in an optimized adaptability of the Sauganschlussstutzens 88 in particular with respect to an application disposed therein such as a suction nozzle or a suction pipe. As a result, the housing device 22 can be repositioned relative to, for example, the suction nozzle or a suction pipe, so as to obtain accessibility or improved accessibility in a suction operation even in areas which are not accessible or difficult to access. The suction material container 80 comprises a first region 136. This is bounded by the wall region 104. The first region 136 has an intake space 138 into which the suction port opening 90 opens. The first region 136 has at least approximately a triangular cross-sectional shape (FIG. 3).

In a suction operation, the negative pressure of the interior 84 ensures that the fallback flap 140 is opened and suction material can thus be coupled into the interior space 84 of the suction material container 80 at the suction connection opening 90 on an inner side of the wall region 104 , In a non-suction operation, that is, when there is no negative pressure of the interior space 84, the fall-back flap 140 is closed. It is thereby prevented that suction material can fall out of the interior space 84 to the outside through the suction connection opening 90.

The suction chamber 138 is part of the interior 84.

The suction material container 80 further comprises a second region 142 which, relative to a transverse direction to the height direction 34 (when the suction material container 80 is arranged on the housing device 22) is arranged next to the first region 136 of the suction material container 80 and the suction blower device 26 is arranged facing ,

Between the first region 136 and the second region 142, a wall 144 is arranged. The wall 144 in this case has the suction port 90 to. It forms a baffle wall and also a protective wall.

In the second region 142, a filter device 146 (FIGS. 3, 5) is arranged, in particular in the form of a cartridge filter. The filter device 146 is detachably positioned on the suction material container 80 (FIG. 5). When arranged on the housing device 22 suction material container 80, the filter device 146 of the suction fan 26 is connected upstream. It prevents a supply of suction material and in particular dust to the suction fan device 26 in the housing 24.

The wall 144, facing away from the suction connection opening 90, has a contact surface 148 for mounting the filter device 146. The wall 144 is positioned at an acute angle to the first axis 98 of the first portion 92 of the suction port 88. This acute angle corresponds to the supplementary angle of the angle 102 to 180 °.

The first region 136 and the second region 142 of the suction container 80, which are juxtaposed with respect to a transverse direction to an orientation direction of the wall 144, are fluidly connected to one another via one or more openings 150. It can thereby become one

Suction flow can be generated in the suction space 138. The opening or openings 150 are, for example, as openings in the

Formed wall 144 or the wall 144 in the interior 84 of the suction container 80 has such a length that an opening distance between a wall portion 152 of the outer wall 82 of the suction container 80 and the wall 144 is located. The wall region 152 is provided in particular for abutment or support on the web element 46 and in particular on the shoulder 76.

The suction material container 80 further comprises a third region 154. The third region 154 has an underside 156.

If the suction material container 80 is arranged on the housing device 22, then the suction material container 80 is supported on a support surface 158 (FIG. 5) on the upper side 44 of the holder 32. The support surface 158 is between the first end 52 and a connecting portion of the support member 46 is arranged with the holder 32.

The suction container 80 thereby impedes the removability of the battery device 30 from the holder 32 in the withdrawal direction 58a or its applicability in the insertion direction 58b not.

In the described embodiment, the suction material container 80 is supported on its underside 156 on the holder 32 down from, that is from the suction fan 26 away down; In particular, the support on the holder 32 is opposite to the height direction 34 of the holder 32 away. The suction material container 80 sits with its underside 156 on the holder 32. It is also possible that the support of the suction container 80 downwards not exclusively on the underside 156 of the suction container 80 or not on this underside 156, but that the suction container 80 one or more spaced from the underside support surfaces for support down to the Holder 32 has. Preferably, the support is such that the removal in the removal direction 58a or the insertion in the insertion direction 58b of the battery device 30 on the holder 32 is not hindered.

By way of example, the third region is formed "two-pronged", wherein an abutment takes place by means of a transverse region between the two prongs on the holder 32.

The third area 154 connects to the bottom 156 to the first area 136. The third region may be arranged and formed such that it overlaps in an extension at least partially with the second region 142, or that there is no such overlap region. The suction material container 80 has a suction container axis 160 (see FIG. 1). In particular, the suction material container 80 has its longest dimensions along the suction-material container axis 160. The Entnahmestbehälterachse 160 runs at least approximately parallel to the web member 46 outside the paragraph 76th

The third region 154 extends along the suction container axis 160. When the suction material container 80 is arranged on the housing device 22, the suction container axis 160 is oriented parallel to the handle axis 38 or at a small acute angle, which is in particular below 30 ° and preferably below 20 ° is, and for example, at about 15 °, oriented to the handle axis 38.

The third region 154 of the suction container 80 has a receiving space 162 for suction, which is part of the interior space 84 and is connected to the suction space 138. As will be explained in more detail below, the receiving space 162 is formed as a flow rest region (flow rest zone), in which the Strömungsaufschlagung compared to the Einsaugraum 138 and a receiving space of the second portion 142 for the filter device 146, via which the filter device 146 is acted upon, is reduced , As a result, the possible whirling up of suction material, which is located in the receiving space 162 of the third area 154, is at least reduced. It can be realized in a simple way a separator.

When the suction material container 80 is arranged on the housing device 22, the third region 154 with its receiving space 162 extends approximately over the height (in the height direction 34) of the free space 48. Relative to the height direction 34 (or the suction container axis 160) extends the third area 154 with its receiving space 162 up to At least approximately the wall portion 152, which is adapted to the shoulder 76.

Between the intake space 138 and the receiving space 162, a flow deflection region 164 is formed in the interior space 84 of the suction material container 80. A suction flow entering at the suction connection opening 90 (provided with the reference symbol 166 in FIG. 3) is oriented with a main flow direction transversely and in particular perpendicular to the suction connection opening 90 or to the wall region 104. The wall 144 forms a baffle wall and protective wall, which causes a flow deflection with a

Main flow direction 167, which is at least approximately parallel to the wall 144.

This is followed by the flow deflection region 164, at which a flow deflection takes place for feeding to the filter device 146. By the

Flow deflection is a Abscheidereffekt realized for solid suction, which can "fall" in the receiving space 162.

Downstream of the bottom 156, the receiving space 162 adjoins the flow deflection region 164. This is flow-calmed by the "cover" with the flow deflection region 164 as described above.

Adjoining the wall region 104 of the outer wall 82 of the suction material container 80 is a wall region 168, which closes the second region 142 to an upper side 170 of the suction material container 80, which faces away from the underside 156.

The second region 142 of the suction material container 80 has an end face 172 which is designed to bear an associated end face 174 on the housing 24 and the housing device 22.

Furthermore, a contact element 176 for the filter device 146 is arranged on the housing device 22 and in particular on the housing 24. If the suction container 80 is fixed to the housing device 22, then the filter device 146 can be positioned appropriately between the contact element 176 and the wall 144 hold. It can be provided elements which provide a positive connection in transverse directions to the Sauggebläseachse 82.

The end face 182 and / or the end face 174 may be associated with one or more sealing elements to obtain an airtight connection when the suction container 80 is disposed on the housing means 22.

The hand-held suction device 20 has a pivot bearing 178 (Figure 2), which in a certain angular range, a pivoting of the suction container 80 on the housing device 22 allows (Figures 7, 8, 11).

In one embodiment, the flange 70 is disposed on the housing device 22 and in particular on the housing 24 on an upper side 180. The flange 70 is formed like a tab (see for example Figure 5) and extends relative to the Sauggebläseachse 62 in a finite angular range, for example, less than 40 ° and in particular less than 30 ° relative to opposite ends 182 of the flange 70.

The flange 70 has the holder 32 facing a survey 184 (Figures 2, 12).

The elevation 184 is in particular web-shaped.

The elevation 184 forms an immersion element 186. A counter-flange 188 is arranged on the wall region 168 of the second region 142 of the suction-material container 80 (FIGS. 2, 12). The mating flange is also formed like a lug. It comprises a groove-shaped recess 190, for example, which is an immersion recess for the immersion element 186 of the housing device 22. When the suction container 80 is fixed to the housing means 22, the immersion member 186 is immersed in its associated immersion recess 190 (Figure 2).

When held on the housing device 22 Suction container 80, this supports with its underside 156 on the holder 32 from.

In one exemplary embodiment, a guide device 192 is arranged on the holder (and / or the suction material container 80) (see FIG. 5), which ensures a guide on the holder 32 when the suction material container 80 is inserted.

In one embodiment, the guide means 192 comprises one or more webs and the suction material container 80 comprises on its underside 156 counter elements for the webs such as grooves or the like.

The hand-held suction device 20 comprises a locking device 194, by means of which the suction material container 80 can be locked to the housing device 22. The locking device 194 has a housing device part 196, which is arranged on the housing device 22, and has a Sauggutbehälterteil 198, which is arranged on the suction material container 80.

The housing device portion 196 of the locking device 194 is between see the holder 32 and the top 180 of the housing device 22 is arranged. It is arranged in particular on the web element 46 and preferably in the region of the projection 76. The suction material container part 198 of the locking device 194 is arranged between the underside 156 and the wall region 168 of the suction material container 80. In particular, it is positioned approximately centrally between this wall region 168 and the underside 156.

The suction-material container part 198 of the suction-material container 80 is positioned below the second region 142 of the suction-material container 80 and below the first region 136 or at the transition from the first region 136 to the third region 154.

In one embodiment (see also FIGS. 9 and 10), the housing device part 196 of the locking device 194 comprises spaced-apart latching noses 200a, 200b. The detents 200 a and 200 b are spaced in a transverse direction to the height direction 34. The latching noses 200a, 200b each have an undercut surface 202, which is oriented transversely to the height direction 34. The suction material container part 198 of the locking device 194 has a counter element 204a for the latching lug 200a, and has a counter element 204b for the latching lug 200b. The counter-elements 204a and 204b are adapted to the latching noses 200a, 200b formed so that an investment on the respective undercut surface 202 is possible and a corresponding positive fit then a mobility in a direction 206 (Figure 9), which transverse to a distance direction between the Latches 200a, 200b is located, and which is transverse to the height direction 34, is locked.

The counter-elements 204a, 204b are designed so elastically or so kraftbeaufschlagt arranged that for leading out of the undercut surface 202, a force must be exerted and in particular an elastic force must be exercised. For this purpose, an actuating element 208a is assigned to the counter element 204a, and an actuating element 208b is assigned to the counter element 204b (FIG. 6). The actuators 208a, 208b are switch-like and sit on an outer side of the suction container 80. They are parallel to the distance direction between the locking elements 200a, 200b and transverse to the height direction 34 (when the suction container 80 is fixed to the housing means 22).

When the suction container 80 is fixed to the housing means 22, then the actuators 208a, 208b are at the level of the heel 76. They are at the approximate height of the switch 42. At the suction container 80 they are at the transition region of the first region 136 to the third area 154.

The suction material container 80 is designed so that it can be held with one hand, in particular by gripping on the outer wall 82, in particular on the first region 136 and third region 154 and while the actuating elements 208a, 208b are operated in particular with thumb and forefinger. This makes it possible to solve the suction material container 80 via the locking device 194 with one hand and remove. Accordingly, there is a one-hand applicability.

The locking device 194 is formed with the detents 200a, 200b and the counter-elements 204a, 204b so that when inserting the suction container 80 on the housing means 22, an automatic locking can be achieved without the actuators 208a, 208b must be operated; these are necessary only for the release of the locking device 194. In one embodiment, the locking device 194 is associated with a guide device 210, by means of which, with a sufficiently small distance between the housing device 22 and the suction material container 80 relative guidance is achieved to each other. As a result, a pre-centering for locking the locking device 194 can be achieved.

The guide device 210 is in particular adapted to the guide device 192 of the holder 32. To remove the suction material container 80, which is locked to the housing device 22 (see, for example, FIG. 1), the actuating elements 208a, 208b are pressed simultaneously. The corresponding hand, whose fingers actuate the actuators 208a, 208b, holds the suction container 80. This then moves forward (on the pivot bearing 178) away from the housing means 22 (away from the housing 24) and away from the holder 32 tilted up.

The pivot bearing 178 has a housing device part, namely the immersion element 176 and the flange 70, on which the immersion elements 186 is arranged. This housing device part of the pivot bearing 178 is on the inside, that is, the holder 32 facing arranged. The

Swivel bearing 178 further has a suction material container part, which is formed over the counter flange 188 with the immersion recess 190. The immersion element 186 is adapted to the immersion recess 190 and in particular such a play is provided that a pivotability is possible up to a certain position range without the immersion element 186 (completely) emerging from the immersion recess 190. By placing the suction material container part of the pivot bearing 178 against the housing device part of the pivot bearing, a pivot axis 212 (cf. FIG. 12) is formed, which enables the pivotability. The position of the pivot axis 212 is usually not fixed, but varies with the pivot position of the suction container 80 to the housing means 22. Up to a certain pivot position of the suction container 80 is still coupled to the housing device 22 and the holder 32. In particular, the guide device 192 ensures a corresponding coupling.

FIG. 7 shows a corresponding pivoting position after the locking device has been released, whereby a pivotability of the suction material container is made possible and the immersion element 186 is immersed in the immersion recess 190.

The suction material container 80 lies in a swivel angle 213 relative to the housing device 22. This swivel angle 213 is defined, for example, by the angle between the end surfaces 172 and 174.

FIG. 8 shows a further position in which the pivoting angle 213 is increased. In this position, the suction material container 80 is then decoupled from the holder 32. It is now possible to dive the immersion element 186 out of the immersion recess 190.

In the angular position according to FIG. 8, the holder 32 is still down in the path of the suction material container. In another movement with a

Pivoting portion (Figure 11), the suction material container 80 is positioned so that it can be removed down, that is, that the holder 32 is no longer in the way.

It can then, as indicated in Figure 12, the immersion via the immersion element 186 take place at the immersion recess 190 and thereby a complete detachment of the suction material container 80 are achieved by the housing device 22. The removed suction material container 80 can then be emptied and possibly cleaned.

After removal of the suction container, the state shown in Figure 5 is present.

The filter device 146 can be removed from the suction material container 80 (without tools). To fix the suction container 80 to the housing device 22 is proceeded in the reverse steps. The filter device 146 is inserted into the second region 142 of the suction material container 80. The wall 154 forms in particular a contact surface. The immersion recess 190 is "hooked" into the immersion element 186 of the flange 70 on the housing device 22. It is then the suction container 80 to the housing means 22 and the holder 32 to be pivoted. From a certain angular position, the guide device 192 acts on the underside 156 of the suction material container.

Furthermore, then the guide device 210 of the locking device 194 act. In another Zubewegung a latching can be done on the locking device 194 and the suction material container 80 is locked to the housing device 22 and thereby supported on the holder 32.

In particular, the locking takes place with a certain biasing force, which presses the end face 172 against the end face 174 in order to obtain a high density. As a result, if appropriate, the filter device 146 can also be clamped.

The housing device 22 is constructed, for example, by means of two half-shells 300, 302 (FIGS. 6, 19), which abut one another on a center plane 304 and, in particular, are locked together. The intermediate region 40 is associated with at least one rib 306 (FIG. 19). This at least one rib 306 extends at least approximately parallel to the upper side 44 of the holder 32 up to the web element 46.

The at least one rib 306 serves as a reinforcing rib for the mechanical stabilization of the housing device 22. In particular, each housing shell 300, 302 has at least one corresponding rib 306.

The at least one rib 306 lies in an extension (at least approximately parallel to the upper side 44) of the bar element 46. It consequently receives main locking forces of the locking device 194 transversely (and in particular perpendicularly) to the height direction 34 in the corresponding longitudinal direction.

The at least one rib 306 has at least one passage 308, in particular in the form of a notch, through which one or more electrical connection lines 56 to the suction fan device 26 are then passed. In particular, notches of mutually corresponding ribs 306 of the half-shells 300 and 302 then form the corresponding lead-through opening.

Furthermore, the combination of the ribs 306 or a partial combination of the ribs 306 is formed as a wall 310, which is a flow barrier for flow of air from the housing 24 into the handle 36; The wall 310 largely prevents the penetration of flow air from the housing 24 into an interior of the handle 36. The intermediate area 40 further comprises, in particular limited by ribs 306, a storage space 312, in particular for cables, and in particular for the electrical connection lines 56. On the holder 32, a contact strip 314 is arranged for battery contacts of the battery device 30.

From there, the electrical connection lines 56 (with the switch 48 therebetween) lead to a circuit board 316 on or in the housing 24.

In particular, in the manufacture of the suction device 20, the combination of contact strip 314, electrical connection lines 56 and board 316 is made as a unit. This unit is then inserted completely into the corresponding half-shell (for example, the half-shell 300). In particular, the circuit board 316 is inserted at the intermediate region 40 or in the housing 24. For this assembly, a game of connecting lines 56 is necessary and the storage space 312 can then record accordingly "excess" line length.

In the manufactured suction device 20 then the half-shells 300 and 302 are connected together.

In one embodiment, the handheld suction device 20 includes an accessory holder 214, such as a suction nozzle. The holder 214 is arranged in particular on the upper side 180 (FIG. 1) of the housing device 22.

In one embodiment, the holder 214 includes a clip 218, or is formed by a clip 218. By this clip 218, an elastic force in the direction of the top 180 of the housing device exercisable or in the direction of the top away exercisable. As a result, for example, the clip 218 can be inserted into an opening of a suction nozzle and the suction nozzle is pressed down against the upper side 180 of the housing device 22.

In one embodiment, the suction device has connections 220a, 220b for a carrying belt 222. For example, on the holder 32 and on the housing device 22 in the region of the housing 24 and in particular in the area the second end 66 formed through openings in which, for example, respective rings are positioned. These in turn can then receive the carrying belt 222. The handheld suction device 20 of the invention operates as follows:

For a suction operation of the suction material container 80 is arranged on the housing device 22 and locked with this. The suction container 80 is supported on the holder 32 for the battery device 30 down from. The suction container 80 is applied to the web member 46.

A battery device 30 can be inserted into the insertion device 58b without being impeded by the suction material container 80 or can be removed in the direction 58a. Even if the suction container 80 is fixed to the housing device 22, the battery device 30 can be removed or inserted.

The hand-held suction device 20 has with the handle 36 a kind of pistol grip. Heavy components of the hand-held suction device 20, namely, the suction fan 26 and the battery 32, are disposed on different sides of the handle 36. The suction device 20 is designed such that a center of gravity compensation takes place, so that a comfortable working results. In the suction operation, a suction flow is generated by the suction fan 26; The suction blower device 26 ensures that the interior 84 of the suction material container 80 is pressurized with negative pressure. The vacuum injection takes place through the filter device 146. Suction material is sucked in via the corresponding suction flow (air flow). It flows through the suction connection piece 88. In the transition from the second region 94 to the first region 92 of the Sauganschlussstutzens 88 there is a flow deflection corresponding to the angular arrangement of the second Axis 100 to the first axis 98 (relative to a main flow direction). Suction material in the suction flow penetrates through the suction connection openings 90 into the suction chamber 138 of the suction material container 80. The wall 144 acts as a baffle wall and also as a protective wall for the filter device 146. It ensures a flow deflection with a main flow 167.

The suction flow 167 is directed into the receiving space 162 of the suction container 80. Further, a flow deflection follows through the opening 150 to the filter device 146. It is achieved by a settling effect for solid suction material.

The receiving space 162 of the third area 154 is directed outside the throughflow area to the filter device 146. There is formed a flow rest zone in which the suction material "can settle", so that a Aufwirbelungsneigung is reduced in the receiving space 162.

The main receiving area for suction material of the suction container 80 is opposite to the handle 36 and has a height above the holder 32 which substantially corresponds to the height (in the height direction 34) of the handle 36 above the holder 32.

For suction operation, the suction connection stub 88 is rotatable relative to the remainder of the suction material container 80 (relative to the outer wall 82) via the pivot bearing 106 (FIGS. 13 to 18). The second region 94 of the Sauganschlussstutzens 88 can be changed in its relative position to the rest of the suction material container 80. It is possible to adapt to a special cleaning application. As a result, the position of the housing device 22 with the suction material container 80 can be varied relative to, for example, a suction nozzle or a suction pipe in order to obtain an optimized suction result at an application. To set a particular rotational position 128, an operator holding the suction device 20 with one hand on the handle 36 can rotate with the other hand by pushing the actuator 128 to release an existing position of the suction port 88, and it Then, a rotation can be performed on the grip ring 134 to obtain the desired setting.

In particular, discrete rotational positions are provided and latching can take place when a latching lug 120 is opposite a latching counterpart element 118.

To remove the suction container 80 from the housing device 22, the actuating elements 208a, 208b are pressed. An operator holds, for example, the suction device 20 on the handle 36 with one hand and then acts with fingers of the other hand on the actuators 208a, 208b. With the latter hand, he can then hold the suction container 80.

By actuating the actuators 208a, 208b, the latch on the latch 194 is released. The suction container 80 can then be pivoted away from the housing means 22 by increasing the pivot angle 213.

It is a Wegschwenkbarkeit about the pivot bearing 178 to a certain maximum angle possible. Then immersion of the immersion element 186 through the immersion recess 190 is possible and the suction material container 80 can then be completely detached from the housing device 22. It can then be emptied and, if necessary, cleaned. The filter device 146 is detachably arranged on the suction material container 80. It can be removed to allow a better access to the cleaning of the suction container 80 in its interior 84. Furthermore, the filter device 146 is thereby exchangeable in a simple manner. The inventive solution results in a simple operation of the suction device 20 with extensive operating options. The suction material container 80 can receive a relatively large amount of suction material via its third region 154.

In particular, the battery device 30 can be changed. The change is possible in a simple manner without the suction material container 80 having to be removed.

It is possible to obtain a mains-independent suction operation.

For example, the hand-held suction device 20 has multiple modes of operation with different power levels for the suction fan 26.

The housing device 22 is constructed mechanically stable. It is connected to the holder 32 both via the handle 36 and via the intermediate region 40. Through the intermediate region 40 between the housing 24 and thus between the suction fan device 26 and the handle 36 results in a mechanically stable connection of the rod member 46 to the housing means 22. It can act on the locking device 194, are derived in the housing device 22. As a result, the housing device part 196 of the locking device 194 can also be arranged on the web element 46.

The shoulder 76 results in a support of the suction material container 80 on the web element 46 via the wall region 152 downwards.

This results in a stable fixation and locking of the suction material container 80 on the housing device 20, wherein a fluid-tight connection of the suction Good container 80 is reached at the end face 172 to the end face 174 of the housing device 22.
