Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a suction device as described at the beginning of this document, which can be used in a variety of ways with a compact design and can be operated simply and comfortably.

[0007] The technical problem is thus solved according to the present invention in the suction device described at the beginning of this document, namely, the suction device includes a suction head, a suction container for receiving suction material, a fan device, a gripping bow-shaped member pivotally supported at the suction head, a holding device arranged at the suction head, and a receiving area in the space of the holding device for at least partially receiving the cable of the suction device, wherein the receiving area is constructed on the outside of the suction head, wherein the gripping bow-shaped member is pivotable from a first position to a second position, wherein in the first position the gripping bow-shaped member occupies a stationary position, and in the second position the suction device can be held and / or moved by means of the gripping bow-shaped member, and wherein when the gripping bow-shaped member is in the first position, the gripping bow-shaped member segmentally defines the boundary of the receiving area.

[0008] The operator can pivot the gripping bow of the suction device from a first position to a second position. In the first position, the gripping bow occupies a retracted position, in which the gripping bow is segmentally abutted against the suction head and / or oriented almost horizontally. In the second position, the gripping bow protrudes almost vertically from the suction head.

[0009] In the second position, the operator can easily hold or move the suction device and / or suction head by gripping the bow-shaped component. For example, the operator can roll or slide the suction device on the ground by gripping the bow-shaped component. For example, the operator can remove the suction head from the suction container that is releasably connected to the suction head and reconnect it to the suction container by gripping the bow-shaped component.

[0010] The cables of the suction device, such as electrical connection cables, can be arranged and / or held in the retaining device and the associated receiving area. The cables can be arranged in the retaining device and the receiving area, for example, in a coiled state.

[0011] When the gripping bow-shaped component is in the second position, the operator can enter the receiving area from above. Cables can then be arranged, for example, within the receiving area and at the holding device. The operator then moves the gripping bow-shaped component to, for example, the first position, in which the gripping bow-shaped component is adjacent to the receiving area.

[0012] When the gripping bow-shaped component is in the first position, the suction head has a particularly compact shape. This allows for particularly space-saving storage of the suction device, including the cables that may be arranged thereif necessary.

[0013] By segmentally defining the boundary of the receiving area with the gripping bow when it is in the first position, the suction head can be designed with particularly space-saving features and fewer components. The gripping bow in the first position serves to block the receiving area upwards, thus eliminating the need for additional mechanical components.

[0014] It may be advantageous that the gripping bow has a pivot angle range of at least 85° and / or at most 95° between the first and second positions. The gripping bow can thus, for example, swing from a horizontal position to an approximately vertical position.

[0015] When the gripping bow changes from the first position to the second position, the gripping element of the gripping bow moves away from the receiving area, for example, to allow the operator to grip the gripping bow.

[0016] When the gripping bow changes from the first position to the second position, the gripping element of the gripping bow moves upward in at least a segmental manner with respect to the height of the suction device, for example, in order to allow the operator to grip the gripping bow.

[0017] It may be advantageous that the gripping bow-shaped member, in the first position, is at least segmentally adjacent to and / or surrounds the cap element of the suction head. This allows the suction head to be designed to be particularly compact.

[0018] Specifically, it can be specified that when the gripping bow-shaped component is in the first position, a gripping area is provided in the space for gripping the gripping bow-shaped component, wherein the gripping area is at least partially constructed in the receiving area. The operator can easily grip or hold the gripping bow-shaped component in the first position using the gripping area. Furthermore, the receiving area serves both as a storage area for the cable of the suction device and as a gripping area. This achieves a particularly compact design for the suction head.

[0019] When the gripping bow is in the first position, the gripping area is, for example, at least segmented, between the outer side of the gripping bow and the suction head.

[0020] When the gripping bow is in the first position, the gripping area is, for example, at least segmented between the gripping bow and the cap element of the suction head.

[0021] When the gripping bow is in the first position, the gripping area is constructed, for example, between the gripping element of the gripping bow and the outside of the suction head, wherein the gripping bow is connected to the suction head by means of at least one leg element.

[0022] When the gripping bow is in the first position, for example, there is an opening above the receiving area between the gripping bow and the suction head, which is arranged above the receiving area with respect to the height of the suction device.

[0023] When the gripping bow is in the first position, for example, there is a first lateral opening leading to the receiving area and a second lateral opening leading to the receiving area between the gripping bow and the suction head, wherein a retaining device is arranged between the first lateral opening and the second lateral opening.

[0024] The upper opening and / or the first and second lateral openings allow the gripping bow-shaped component to be grasped or held particularly easily by the operator's hand in the first position.

[0025] When the gripping bow is in the first position, for example, there is a first lateral opening leading to the receiving area and a second lateral opening leading to the receiving area between the gripping bow and the suction head, wherein the first lateral opening and the second lateral opening extend in the height direction of the suction device between the bottom section defining the boundary of the receiving area and the gripping bow, respectively.

[0026] When the gripping bow is in the first position, the first leg element and / or the second leg element of the gripping bow are oriented, for example, laterally and particularly perpendicularly to the height direction of the suction device, wherein the gripping element of the gripping bow is connected to the suction head by means of the first leg element and / or the second leg element.

[0027] When the gripping bow is in the first position, the gripping bow contacts, for example, at least 50% of the total length of the gripping bow, the abutment area formed on the outside of the suction head.

[0028] When the gripping bow is in the first position, the gripping bow is spaced further apart from the longitudinal central axis of the suction device than the cover element of the suction head facing the wall element of the gripping bow, wherein the longitudinal central axis is oriented in the height direction of the suction device. The gripping bow thus partially forms, for example, the outer contour of the suction head, allowing the suction head to be designed to be particularly compact with the gripping bow.

[0029] When the gripping bow is in the first position, the gripping bow does not extend from the cover element of the suction head, for example, in the height direction of the suction device.

[0030] When the gripping bow is in the first position, the gripping bow retracts relative to the cover element of the suction head, for example, in the height direction of the suction device.

[0031] When the gripping bow is in the second position, the gripping area in the space belonging to the gripping bow is, for example, at least segmented between the gripping bow and the outside of the suction head.

[0032] When the gripping bow is in the second position, the gripping area in the space belonging to the gripping bow is, for example, at least segmented, between the gripping bow and the cap element of the suction head.

[0033] When the gripping bow is in the second position, the gripping elements of the gripping bow for the operator to grip the gripping bow are arranged spaced apart from the suction head and / or the cover element of the suction head.

[0034] When the gripping bow is in the second position, the first leg element and / or the second leg element of the gripping bow are oriented at least approximately parallel to the height direction of the suction head, wherein the gripping element of the gripping bow is connected to the suction head by means of the first leg element and / or the second leg element.

[0035] When the gripping bow is in the second position, for example, the operator can carry and / or hold and / or move the suction device and / or suction head by means of the gripping bow.

[0036] It may be advantageous that the gripping bow has a gripping element for the operator to grip, wherein the gripping element is connected to the suction head by means of a first leg element and / or a second leg element of the gripping bow. The first leg element and / or the second leg element allow for a mechanically stable and technically simple connection between the gripping bow and the suction head.

[0037] It may be advantageous that the pivot axis of the gripping bow is oriented transversely to, and in particular perpendicularly to, the height direction of the suction device. This allows for a compact and symmetrical design of the suction head and the gripping bow arranged thereon.

[0038] Specifically, it can be specified that the gripping bow-shaped component is arranged in the upper end region above the suction head in the height direction of the suction device. This allows the operator to easily access the suction device from above.

[0039] It may be advantageous that an abutment area for gripping the bow-shaped component is formed on the outer side of the suction head, wherein the bow-shaped component abuts against this abutment area in a first position. The bow-shaped component can thus abut against the suction head in a defined position.

[0040] The adjacent areas are constructed to be flat, for example, at least in sections.

[0041] The adjacent area is, for example, at least a section of adjacent containment area.

[0042] The area that is adjacent to gradually becomes an area that accommodates others.

[0043] The contact area is located, for example, in a plane oriented laterally and, in particular, perpendicularly to the height direction of the suction device.

[0044] The contact area includes, for example, a first sub-region for contacting a first leg element of a grasping bow and a second sub-region for contacting a second leg element of a grasping bow, wherein the first leg element is connected to the second leg element by means of a grasping element of the grasping bow.

[0045] The contact area includes, for example, a first sub-region for contacting a first leg element of the grasping bow-shaped member and a second sub-region for contacting a second leg element of the grasping bow-shaped member, wherein a cover element of a suction head is arranged between the first sub-region and the second sub-region. Thus, for example, a cover element of a suction head is arranged between the first sub-region and the second sub-region.

[0046] The contact area is arranged in a lateral direction, for example, with respect to the height direction of the suction device and particularly perpendicular to the lateral direction, in the outer area and / or edge area of ​​the suction head.

[0047] Specifically, it can be specified that when the gripping bow-shaped component is in the first position, the accommodating area is arranged in the height direction of the suction device between the gripping bow-shaped component and the channel device associated with the exhaust fan device for guiding process air at the suction head.

[0048] It may be advantageous that the suction connection end associated with the exhaust fan assembly and / or the opening device for cooling air associated with the exhaust fan assembly and / or the operating element device of the suction equipment are arranged on the first side of the suction equipment, and the holding device and / or receiving area of ​​the suction equipment and / or the air outlet associated with the exhaust fan assembly are arranged on the second side of the suction equipment opposite to the first side. These components of the suction equipment thus allow for easy access by the operator and / or space-saving arrangement at the suction equipment.

[0049] It may be advantageous that the retaining device is held on the suction head by means of a wall element, which is arranged in the height direction of the suction equipment between the channel device for guiding process air at the suction head and the receiving area. This provides mechanically stable support for the retaining device and / or the receiving area at the suction head.

[0050] The accommodating area is defined, for example, by a lateral section constructed on the outside of the suction head, which is lateral to the height direction of the suction device and / or lateral to the abutment area for gripping the bow-shaped part.

[0051] The accommodating area is defined, for example, by a bottom section constructed on the outside of the suction head, which is oriented laterally and, in particular, perpendicularly to the height direction of the suction device.

[0052] The lateral segment defining the boundary of the receiving area is arranged, for example, between the bottom segment of the boundary defining the receiving area and the abutment area for gripping the bow-shaped component.

[0053] The bottom section defining the boundary of the containment area forms, for example, a support surface for arranging cables within the containment area in the height direction of the suction device.

[0054] The minimum angle between the lateral segment of the boundary of the defined containment area and the bottom segment of the boundary of the defined containment area is, for example, at least 60° and / or at most 70°.

[0055] The containment area is arranged, for example, above the channel device for guiding process air at the suction head and / or above the air outlet for guiding process air at the suction head, in the height direction of the suction device.

[0056] The accommodating area extends, for example, at least in sections, between the outer sides of the retaining device and the suction head.

[0057] The containment area extends, for example, at least in sections, between the retaining device and a transverse section arranged on the outside of the suction head, which defines the boundary of the containment area.

[0058] The receiving area is, for example, arranged in a region of space defined by a stable outer contour of the suction head, wherein the outer contour extends through the outside of the suction head, which is adjacent to the receiving area in the circumferential direction of the suction head, and wherein the circumferential direction is oriented transversely to and particularly perpendicular to the height direction of the suction device.

[0059] The outer contour, for example, has at least a constant curvature and / or a constant radius of curvature.

[0060] The outer side of the retaining device is located, for example, within the outer contour.

[0061] The receiving area may be constructed, for example, as a cut and / or groove and / or recess at the suction head.

[0062] Specifically, it can be specified that the retaining device and / or receiving area are constructed at least approximately symmetrically with respect to a central plane extending parallel to the height direction of the suction device. This enables a symmetrical design of the retaining device and / or receiving area at the suction head, wherein the suction head is, in particular, at least segmentally constructed to be mirror-symmetrical about the central plane.

[0063] The retaining device is arranged in a lateral direction, for example, laterally oriented and particularly perpendicular to the height direction of the suction device, in the outer and / or edge areas of the suction head. The receiving area and / or retaining device are thus easily accessible to the operator. For example, a cable can be arranged in the receiving area and / or retaining device, with a portion of the cable extending beyond the outer and / or edge areas of the suction head.

[0064] The retaining device extends, for example, from the lower end of the receiving area to the upper end, wherein the upper end and the lower end are arranged spaced apart in the height direction of the suction device.

[0065] The retaining device includes, for example, hook elements for retaining and, in particular, suspending cables and / or hook elements configured for retaining and, in particular, suspending cables.

[0066] It may be advantageous that the retaining device has a first region connected to the suction head and a second region connected to the first region, wherein the second region is arranged above the first region in the height direction of the suction device. The retaining device can thus be manufactured and / or constructed in a technically simple manner.

[0067] The second area is, for example, arranged in the end area above the retaining device.

[0068] When the gripping bow is in the first position, the second area rests against the gripping bow, for example.

[0069] The second region protrudes, for example, from the first region in the direction of the cap element of the suction head and / or in the direction of the transverse segment of the boundary of the defined receiving area of ​​the suction head.

[0070] The retaining device, for example, narrows in width from the end of the retaining device away from the grasping bow towards the end of the grasping bow facing the retaining device, wherein the width direction lies in a plane oriented transversely to and particularly perpendicular to the height direction of the suction device. This allows for a simple gripping of the grasping bow by the operator in a first position, wherein the retaining device is then arranged, for example, between different fingers of the operator.

[0071] The retaining device, for example, has an upper end side that is at least approximately parallel to the abutment area for gripping the bow-shaped part arranged at the suction head. This allows the abutment area for gripping the bow-shaped part to be formed at least partially at the retaining device.

[0072] The retaining device, for example, has an upper end side that is oriented flush with the abutment area for gripping the bow-shaped member.

[0073] When the gripping bow is in the first position, the gripping bow rests, for example, against the upper end side of the holding device.

[0074] The retaining device, for example, blocks the cable arranged in the receiving area in a direction oriented above the height of the suction device and / or in a direction pointing toward the cover element of the suction head.

[0075] The retaining device, for example, blocks the cable arranged in the receiving section in an outward direction, wherein the outward direction is oriented transversely to and particularly perpendicular to the height direction of the suction device, and / or wherein the outward direction is away from the direction of the suction head.

[0076] When the gripping bow is in the first position, the retaining device extends, for example, at least in sections, in a direction transverse to and particularly perpendicular to the orientation of the gripping bow.

[0077] In one embodiment, the suction device includes a retaining element for a tubular element used to perform a suction process and / or a blowing process, wherein the retaining element is arranged on the outside of the suction head. The tubular element can thus be secured and / or stored at the suction device.

[0078] Tubing elements may be configured to be rigid and / or flexible. Tubing elements may be, for example, flexible hose elements, such as the suction hose of a suction device.

[0079] The retaining element, for example, is circumferentially arranged with respect to the suction head, perpendicular to the height direction of the suction device, between the gripping bow-shaped component and the operating element device of the suction device. This allows the tubular element to be arranged at the suction device spaced apart from the retaining device and / or the receiving area.

[0080] The retaining element, such as the suction head, is circumferentially arranged with respect to the height of the suction device and is perpendicular to the height of the suction device. The gripping bow-shaped element is connected to the suction head by means of the pivot hinge.

[0081] The retaining element, for example, is arranged at least approximately at the height of the abutment area for gripping the bow-shaped part in the height direction of the suction device.

[0082] The retaining element is arranged in a lateral direction, for example, with respect to the height direction of the suction device and particularly perpendicular to it, in the outer and / or edge areas of the suction head. This allows the retaining element to be easily accessible to the operator at the suction device.

[0083] It may be advantageous that the suction device's cable is arranged as a coiled wire, and particularly suspended as a coiled wire, in the receiving area. The cable can thus be stored simply and space-savingly in the holding device and the receiving area.

[0084] Specifically, it can be specified that when the gripping bow-shaped component is in the first position, the movement of the cable arranged in the receiving area is blocked upward with respect to the height of the suction device by means of the gripping bow-shaped component.

[0085] Specifically, it can be specified that when the gripping bow-shaped component is in the second position, the receiving area can be accessed by the operator from the outside and / or the receiving area is an open area. The cable can then be arranged in the receiving area, for example, and as a coiled wire.

[0086] In one embodiment, the suction device includes at least one accessory holding element for receiving and / or storing accessories for the suction device, wherein the at least one accessory holding element is arranged at a cover element of the suction head. This allows for simple and safe holding and / or storage of accessories at the suction device.

[0087] In particular, it can be specified that the cover element of the suction head has an upper side on which a support surface for arranging and / or storing accessories for the suction device is formed, and it can also be specified that when the gripping bow-shaped member is in the second position, accessories for the suction device can be arranged and / or stored on the upper side. Thus, for example, accessories can be placed or temporarily stored on the upper side when using the suction device.

[0088] In particular, it can be stipulated that the exhaust fan device be located at the suction head.

[0089] In one embodiment, the suction device includes a locking device for securing and / or locking the gripping bow-shaped member in a first position. The gripping bow-shaped member can be secured and / or locked at a holding device, particularly by means of the locking device.

[0090] In one embodiment, the suction device includes a spring mechanism associated with a gripping bow-shaped member, wherein the gripping bow-shaped member is movable from a first position to a second position in the direction of or opposite to the spring force applied by the spring mechanism.

[0091] In particular, it can be specified that the gripping bow-shaped component is pivotally supported at the cap element of the suction head by means of at least one pivot hinge.

[0092] At least one pivot hinge includes, for example, a sleeve element arranged at the cover element for receiving at least one pivot hinge journal element, wherein the journal element is arranged at the gripping bow and particularly at the leg element of the gripping bow.

[0093] A sleeve element for receiving at least one pivot hinge journal element is arranged, for example, on a wall element of a cover element facing a gripping bow, wherein the wall element is oriented transversely and, in particular, perpendicularly to an abutment area for gripping the bow, the gripping bow resting against the abutment area in a first position.

[0094] At least one pivot hinge is arranged at the journal element of the gripping bow, protruding, for example, in the direction of the cover element of the suction head.

[0095] At least one pivot hinge is arranged at the journal element of the gripping bow, extending at least approximately parallel to the pivot axis of the gripping bow.

[0096] At least one journal element of the pivot hinge is arranged, for example, at the end and / or end region of the gripping bow.

[0097] When the gripping bow is in the first position, for example, by applying force to the leg element of the gripping bow, the journal element of at least one pivot hinge can be moved out and / or removed from the sleeve element of at least one pivot hinge, wherein the journal element is arranged at the leg element. Thus, the gripping bow can be installed and / or removed from the suction head in the first position without tools.

[0098] When the gripping bow is in the second position, at least one journal element of the pivot hinge cannot move out and / or be removed from at least one sleeve element of the pivot hinge. This prevents the gripping bow from accidentally disengaging from the suction head in the second position.

[0099] When the gripping bow is in the second position, for example, at least one pivot hinge is provided with a limiting element arranged at the suction head and a stop element arranged at the gripping bow, wherein the cooperation of the limiting element and the stop element prevents the journal element of at least one pivot hinge from moving out and / or being removed from the sleeve element of at least one pivot hinge, and / or when the gripping bow is in the first position, allows the journal element to move out and / or be removed from the sleeve element.

[0100] A limiting element associated with at least one pivot hinge is arranged, for example, in an abutment region for gripping the bow-shaped member, which abuts against the abutment region in a first position.

[0101] For example, a groove is constructed at the gripping bow-shaped part, wherein when the gripping bow-shaped part moves from a first position to a second position, a limiting element associated with at least one pivot hinge can pass through or be passed through the groove.

[0102] Specifically, it can be specified that the gripping bow-shaped component can be installed at the suction head without tools and / or removed from the suction head without tools. Tool-free installation and / or removal of the gripping bow-shaped component at the suction head in the first position is particularly feasible. Tool-free installation and / or removal of the gripping bow-shaped component in the second position is particularly not feasible.

[0103] (Tool-free) installation and / or removal refers in particular to non-destructive installation and / or removal.

[0104] It may be advantageous that the aspirate container and the suction head are connected in a releasable manner. This allows, for example, the suction head to be separated from the aspirate container by the operator to empty the container. The aspirate container can then be reconnected to the suction head.

[0105] It may be advantageous to arrange and / or construct the suction connection end associated with the exhaust fan unit at the suction container. This allows the exhaust fan unit to directly couple the suction airflow into the suction container, where contaminated components of the suction airflow are discharged into the suction container and / or discharged to the filter unit. Clean air is then coupled into the suction head via the exhaust fan unit and coupled out from this suction head via the air outlet.

[0106] In one embodiment, the suction head includes a suction head housing, a receiving area and / or a holding device arranged and / or constructed on the suction head housing.

[0107] It may be advantageous that the cable of the suction device is guided outward from the suction head via a cable outlet, wherein the cable outlet is arranged circumferentially relative to the suction head and spaced apart from the receiving area, wherein the circumferential direction is oriented perpendicular to the height direction of the suction device. The cable thus allows the operator of the suction device to easily access and arrange and / or wind it around the holding device and / or the receiving area.

[0108] The cable outlet is located below the receiving area, for example, in the direction of the height of the suction equipment.

[0109] The cable outlet is, for example, circumferentially arranged between the receiving area and the pivot hinge of the gripping bow, which is connected to the suction head via the pivot hinge.

[0110] The cable outlet, for example, is arranged at least approximately at the height of the channel device used to guide process air at the suction head, in the direction of the height of the suction equipment.

[0111] It may be advantageous for the suction head to have a base element and a housing element disposed on the base element, wherein the housing element is arranged above the base element in the height direction with respect to the suction device, and wherein a receiving area and / or retaining device and / or gripping bow and / or a cover element of the suction head are disposed at the housing element of the suction head. The suction head and / or suction head housing can thus be constructed in a technically simple manner.

[0112] In particular, it may be specified that the suction equipment is set up and constructed as a wet / dry suction device and / or a mobile suction device and / or a stand-alone suction device.

[0113] Process air refers to air that is drawn in by a fan unit via the suction connection of a suction device and then coupled out through an air outlet. Process air should not be understood in particular as air used to cool the fan unit or air associated with the cooling air guiding device of the fan unit.

[0114] The longitudinal axis of a suction device refers to the longitudinal axis oriented along the height of the suction device. The suction device may be constructed, for example, to be at least segmentally rotationally symmetric about the longitudinal axis.

[0115] When the suction equipment is in operation and positioned as specified, the longitudinal centerline and / or the height direction are at least approximately parallel to the direction of gravity.

[0116] When referring to “up” or “down” and / or “above” or “below” elements of a suction device, it always refers to the height direction relative to the suction device, which may be based on the fact that the suction device is positioned in a specified manner during operation (e.g., arranged on the ground with rollers).

[0117] Unless otherwise stated, "approximately" and "at least approximately" mean that the geometry deviates from the described ideal geometry by an average of at most 10%, or that the values ​​and / or spacing and / or angles deviate from the described values ​​and / or spacing and / or angles by at most 10%. A percentage deviation of the geometry from the ideal geometry is, for example, the average deviation of the width and / or length and / or height of the geometry from the width and / or length and / or height of the ideal geometry.

[0136] The same or similar elements are assigned the same reference numerals in all the figures. Detailed Implementation

[0137] exist Figures 1 to 17 An embodiment of the suction device shown and labeled therewith with reference numeral 10 is a portable suction device and designed as a stand-alone instrument. The suction device 10 is configured, for example, as a wet / dry suction device.

[0138] The suction device 10 includes a suction container 12 with a receiving space 14 for the suction material. The suction container 12 is configured as a barrel and, for example, has a cylindrical shape.

[0139] The suction container 12 includes a bottom element 16 and a wall element 18 disposed at the bottom element 16, the wall element defining the boundary of the receiving space 14. The wall element 18 has, for example, a columnar shape.

[0140] A suction head 20 is disposed at the suction container 12 in a releasable and, in particular, removable manner. A fan device 22 is arranged at the suction head 20, which generates a suction flow when the suction device 10 is in operation. The fan device 22 includes a motor 24, in particular an electric motor, and a fan unit 26 (exhaust fan) driven by the motor 24.

[0141] The suction device 10 has a longitudinal central axis 28, wherein the suction device 10 is configured to be rotationally symmetric about the longitudinal central axis 28, particularly at least in a segmental manner. The aspirate container 12 and / or the suction head 20 are configured, for example, to be rotationally symmetric about the longitudinal central axis 28, at least in a segmental manner.

[0142] When the suction device 10 is positioned as specified in the operating state, the longitudinal central axis 28 is at least approximately parallel to the direction of gravity 30.

[0143] The longitudinal central axis 28 of the suction device 10 specifically refers to an axis that is oriented parallel to the height direction 32 of the suction device 10, wherein, when the suction device 10 is positioned as specified in the operating state, the bottom element 16 is arranged, for example, with respect to this height direction 32, at a lower height than the suction head 20 (that is, much lower or at a lower gravitational potential).

[0144] When referring to “up” or “down” and / or “above” or “below” elements of the suction device 10, the term always refers to the height direction relative to the suction device 10, which may be based on the fact that the suction device 10 is positioned as specified in the operating state.

[0145] On the suction container 12, the suction coupling end 34 is arranged spaced apart from and / or above the bottom element 16. The suction airflow can be coupled into the suction fan device 22 located at the suction head 20 via the suction coupling end through the suction container 12. A connecting device 36 for the tubular elements of the suction device 10 is provided for this suction coupling end 34, wherein the connecting device 36 is, for example, at least partially arranged and / or constructed at the suction coupling end 34.

[0146] Tubing elements can be constructed to be rigid and / or flexible. For example, a flexible hose element, such as the suction hose of suction device 10, can be used to perform a suction process by means of the tubing element by an operator of suction device 10.

[0147] A fluid-efficient, releasable connection can be established between the suction connection end 34 and the tubing element using the connecting device 36. To establish a releasable connection between the tubing element and the connecting device 36, the tubing element includes an adapter device.

[0148] The suction connection end 34 includes, for example, an opening 38, which is configured to be circular and spaced apart from and / or disposed above the bottom element 16 in the suction container 12. The opening 38 is disposed or configured, for example, in the wall element 18 of the suction container.

[0149] A releasable, fluid-efficient connection can be established between the tubular element and the suction connection 34 using the suction connection 34 and the connecting device 36. Thus, a fluid-efficient connection can be established between the tubular element and the receiving space 14 of the suction container 12, for example, via the suction connection 34 through the opening 38.

[0150] In one embodiment, a stand 40 is provided for the suction container 12. This stand 40 is configured, for example, annular and has a receiving area 42 for the suction container 12. The receiving area 42 includes a support surface for the suction container 12, on which the suction container 12 can stand upright. The receiving area 42 is defined, for example, by a protrusion 43 of the stand 40.

[0151] The stand 40 includes rollers 44, and thus the suction device 10 can be moved by the rollers. Alternatively, it can be specified that "removable" rollers are arranged at the stand 40, and the suction device 10 can slide on the ground with the aid of the stand 40 when the rollers are "retracted" or move on the ground with the aid of the rollers when the rollers are "removed," depending on the application.

[0152] The suction container 12 is closed toward the upper side 46 of the suction container (in the direction away from the bottom element 16) by the lower side 48 of the suction head 20 arranged at the suction container 12.

[0153] Alternatively or additionally, the aspirate container 12 may be closed by a separate aspirate container cap (not shown).

[0154] The suction head 20 has a support area 50 through which the suction head can be supported at the suction container 12.

[0155] In order to fix the suction head 20 to the suction container 12, a fixing device 52 is provided, which includes, for example, one or more locking elements 54, through which the suction head 20 can be locked to the suction container 12.

[0156] The suction device 10 has a filter unit 56. The filter unit 56 is arranged between the receiving space 14 and the suction device 22 with respect to the main flow direction 58 of the suction flow generated by the fan device 22.

[0157] The filter unit 56 has a clean side 60 and a dirty side 64. The clean side faces the air inlet 62 of the exhaust fan unit 22 with respect to the main flow direction 58, while the dirty side faces the receiving space 14.

[0158] In the illustrated embodiment, the filter unit 56 is configured as a filter cartridge.

[0159] The filter unit 56 is releasably connected to the suction head 20 via a filter retainer 66. The filter retainer 66 is positioned, for example, below the input end 62 of the exhaust fan unit 22 in the height direction 32.

[0161] The suction head housing 68 includes a base element 72 facing the receiving space 14 of the suction container 12. A lower side 48 is constructed at this base element 72, for example.

[0162] A cover element 74, which is connected to the base element 72, is placed on the base element 72 and has a suction head housing 68 attached to it. For example, a cover element 76 for the suction head housing 68 is constructed at this cover element 74.

[0163] For example, one or more accessory holding elements 77 for clamping and / or storing accessories for the suction device 10 may be arranged and / or constructed at the cover element 76.

[0164] The cover element 76, for example, points upwards to 78. This upwards 78 may be configured and arranged as a support surface for accommodating attachments of the suction device 10. The upwards 78 may be at least sectionally constructed to be flat. For example, grooves for retaining attachments may be formed at the upwards 78.

[0165] The upper side 78, for example, forms the uppermost end side of the suction device 10 and / or the suction head housing 68.

[0166] The housing element 74 is, for example, the housing element above the suction head housing 68. When the suction device is in operation and positioned as specified, the housing element 74 faces the operator of the suction device 10.

[0167] For example, a fixing device 52 and / or a locking element 54 are arranged at the base element 72.

[0168] A retaining element 79 for a tubular element of the suction device 10, such as the suction hose of the suction device 10, is arranged at the suction head 20. The retaining element 79 is arranged, for example, at the cover element 74 of the suction head housing 68.

[0169] On the first side 80 of the suction device 10 and / or the suction head housing 68, an operating element device 82 for operator control of the suction device 10 is arranged. The operator can control the functions of the suction device 10, such as the suction process or the blowing process of the suction device 10, by means of the operating element device 82.

[0170] A cooling air guiding device 84 is provided for the exhaust fan unit 22, which is arranged and / or constructed at the suction head 20. The cooling air guiding device 84 is used to guide cooling air, which can be used to cool the exhaust fan unit 22 during operation.

[0171] The cooling air guiding device 84 includes a cooling air chamber 86 constructed within the inner chamber 70 of the suction head housing 68 between the housing element 74 and the fan assembly 22. This cooling air chamber 86 is fluidly connected to an opening device 88 constructed on the suction head housing 68. The opening device 88 includes, for example, multiple openings and / or ventilation slots through which cooling air can be coupled in and / or coupled out of the suction head housing 68.

[0172] An opening device 88 is constructed, for example, at the base element 72 of the suction head housing 68 and / or on the first side 80 of the suction head housing 68. The opening device 88 is arranged, for example, at approximately the height of the fixing device 52 on the suction head housing 68 with respect to the height direction 32.

[0173] On the second side 90 of the suction device 10 and / or the suction head housing 68 opposite to the first side 80, a holding device 92 for arranging the cable 94 of the suction device 10 and an air outlet for a channel device 96 for guiding process air at the suction head 20 are arranged. The second side 90 is one side of the suction device 10 and / or the suction head housing 68 opposite to the first side 80 and / or the operating element device 82. The first side 80 and the second side 90 are arranged, for example, on different sides of a plane extending through the longitudinal central axis 28.

[0174] Cable 94 is, for example, a connecting cable for supplying electrical power to the suction device 10.

[0175] Cable 94 is guided outward from the inner chamber 70 of the suction head housing 68 through cable outlet 98, where it allows the operator of the suction device 10 to access it.

[0177] The cable outlet 98 is located at approximately the same height as the channel device 96, for example, in the height direction 32.

[0178] The channel device 96 is used to guide process air in the inner chamber 70 of the suction head housing 68.

[0179] The channel device 96 is specifically configured not to guide the cooling airflow. The guiding of the cooling airflow is accomplished by means of the cooling air guiding device 84 and / or by means of the opening device 88.

[0180] The air outlet 101 of the channel device 96 has a first air outlet 102 and a second air outlet 104.

[0196] The first air outlet 102 and the second air outlet 104 are arranged at a distance A1 from each other on the circumference 100 of the suction head housing 68.

[0197] The shortest distance A1 between the first air outlet 102 and the second air outlet 104 is, for example, about 1 cm to 7 cm. The shortest distance A1 corresponds in particular to the shortest distance between the outer contour 116 of the first air outlet 102 and the outer contour 124 of the second air outlet 104, for example, the shortest distance between the outer contour 116 and the second edge segment 128.

[0203] The second channel 108 includes a flow space 149 for air, which is defined by a first wall element 150 and a second wall element 152 spaced apart from the first wall element 150. The first wall element 150 and the second wall element 152 define the boundary of the flow space 149 in particular in a plane oriented transversely to and especially perpendicular to the longitudinal central axis 28 of the suction device 10.

[0204] In the height direction 32, the second channel 108 is defined by wall elements arranged and / or constructed at the suction head housing 68 (not shown).

[0206] The first wall element 150 of the second channel 108 is arranged adjacent to the wall element 120 of the first channel 106. The first wall element 150 intersects with the second wall element 120, for example, in the end opposite to the first air outlet 102 and / or the second air outlet 104 or in the end region of the first channel 106 or the second channel 108.

[0213] The airflow to be coupled out from the inner chamber 70 of the suction head housing 68 can be delivered to the first channel 106 or the second channel 108 by means of the air inlet opening 164 of the first channel 106 and the air inlet opening 160 of the second channel 108.

[0214] To deliver the airflow to be coupled out from the suction head housing 68 from the exhaust fan device 22 to the first air outlet 102 and / or the second air outlet 104, a connecting channel 166 is provided. This connecting channel is arranged in the main flow direction 168 of the airflow to be coupled out between the output end 170 of the exhaust fan device 22 and the first air outlet 102 and / or the second air outlet 104.

[0221] Referring to the lateral direction 174, which lies in a plane oriented transversely to and particularly perpendicular to the longitudinal central axis 28, the output channel 172 is arranged further inward than the connecting channel 166. (The lateral direction 174 hereafter refers to a direction originating from the longitudinal central axis and lying in a plane oriented transversely to and particularly perpendicular to the longitudinal central axis 28, wherein only one of these directions is illustrated by way of example in the figures.)

[0222] It can be specified that a transition region 176 is formed between the output channel 172 and the connecting channel 166, and the transition of airflow from the output channel 172 to the connecting channel 166 is achieved by means of this transition region.

[0223] During the operation of the suction device 10, the main flow direction 168 is reversed by approximately 180° at the transition region 176.

[0224] The connection channel 166 is configured and constructed in such a way that the airflow to be coupled out from the suction head 20 can be divided and / or distributed to the first channel 106 and the second channel 108.

[0227] Air guiding element 178 extends along longitudinal central axis 180. The minimum angle 182 between longitudinal central axis 180 and longitudinal central axis 110 of first channel 106 is, for example, about 30° to 40°.

[0228] The longitudinal central axis 180 of the air guiding element 178 is, for example, at least approximately parallel to the first wall element 150 of the second channel 108.

[0229] The connecting channel 166 has a first sub-region 183a in which the flow cross-section 984 of the connecting channel 166 is at least approximately constant.

[0230] The first sub-region 183a is spatially, for example, the region facing the first side 80 of the suction device 10 and / or the first sub-region 183a is arranged in at least a segmental manner with respect to the lateral direction 174 between the exhaust fan device 22 and the first side 80 of the suction device 10. The first sub-region 183a is the region immediately following the output end 170 and / or the output channel 172 with respect to the main flow direction 168.

[0231] The output channel 172 is spatially arranged in the lateral direction 174 between the exhaust fan device 22 and the first sub-region 183a of the connecting channel 166.

[0232] The connecting channel 166 extends from a first sub-region 183a to a second sub-region 183b within the inner chamber 70 of the suction head housing 68, wherein the flow cross-section 984 of the connecting channel 166 in the second sub-region 183b is wider than the flow cross-section 984 in the first sub-region 183a.

[0233] The flow cross-section 984 of the connecting channel 166 is maximum, for example, at the end region 183c of the second sub-region 183b located at the first channel 106 and / or the second channel 108.

[0234] The flow cross-section 984 of the second sub-region 183b of the connecting channel 166 is minimized, for example, at the end region 183d of the second sub-region 183b of the connecting channel 166 facing the first sub-region 183a.

[0235] The second sub-region 183b is, for example, a region facing the second side 90 in space and / or, for example, arranged in a segmental manner between the exhaust fan device 22 and the second side 90 of the suction device 10 in the lateral direction 174.

[0236] The second sub-region 183b is specifically the region facing the first channel 106 and / or the second channel 108. The connecting channel 166 enters the first channel 106 and / or the second channel 108 in the second sub-region 183b.

[0237] Air guiding element 178 is arranged in a second sub-region 183b of connecting channel 166 and / or spaced apart from the respective air inlet opening 164 or 160 of the first channel 106 or the second channel 108.

[0238] In one embodiment, a connecting device 184 is provided for the first air outlet 102, the connecting device being at least partially arranged and / or constructed at the first air outlet 102 and / or the first channel 106. The connecting device 184 allows a fluidly efficient, releasable connection to be established between the first air outlet 102 and the adapter device 186.

[0239] One or more rib elements 986 for supporting and / or guiding the adapter device 186 are arranged, for example, at the first air outlet 102 and / or the second channel 106. The rib elements 986 can be used to position and / or guide the adapter device 186 into the first air outlet 102 and / or the first channel 106, for example.

[0240] The rib element 986 is oriented, for example, at least approximately parallel to the first longitudinal central axis 110 of the first air outlet.

[0241] The adapter device 186 is part of the tubular element 186a of the suction device 10 (in Figure 2 and 4 (As explained in the text). The tube element 186a is, for example, a suction hose or part of a suction hose of the suction device 10. Airflow can be coupled into the tube element 186a, thereby enabling, for example, a blowing function.

[0242] The suction device 10 includes a sealing device 185 associated with the second air outlet 104, which can occupy a first state and a second state. The sealing device 185 is configured and arranged such that in the first state of the sealing device 185, the coupled output of process air through the second air outlet 104 is released, and in the second state of the sealing device 185, the coupled output of process air through the second air outlet 104 is blocked.

[0243] In the illustrated embodiment, the sealing device 185 can be controlled by means of the adapter device 186. When the adapter device 186 is separated from the connecting device 184, the sealing device 185 occupies a first state, and when the adapter device 186 and the connecting device 184 are connected as specified, the sealing device occupies a second state.

[0244] The adapter device 186 has a shape corresponding to the first air outlet 102 and / or the first channel 106. The adapter device 186 may be introduced into the first channel 106, for example, through the first air outlet 102, or arranged such that the first channel 106 is introduced into the adapter device 186.

[0245] The adapter device 186 has, for example, a cylindrical shape. An airflow space 187 is formed within the adapter device 186.

[0246] When the adapter device 186 is connected to the connection device 184 as specified, the adapter device 186 is arranged, in particular, at least partially, in the inner chamber 70 of the suction head housing 68.

[0247] The adapter device 186 includes, for example, a mechanical connecting element 188, such as a locking element, wherein a releasable connection can be established between the adapter device 186 and the connecting device 184 by means of the connecting element 188.

[0248] The channel device 96 and / or the closure device 185 are configured and constructed such that when the adapter device 186 is connected to the connection device 184 as specified, the second channel 108 is fluid-tightly closed relative to the connection channel 166 within the suction head housing 68. In this case, the process air to be coupled out is coupled out only through the first channel 106 and the first air outlet 102 by means of the channel device 96.

[0249] When the adapter device 186 is separated from the connection device 184, in the inner chamber 70, the first channel 106 and the second channel 108 are both fluidly and effectively connected to the connection channel 166, so that the process air can be coupled out both through the first channel 106 and the first air outlet 102 and through the second channel 108 and the second air outlet 104.

[0250] The sealing device 185 is equipped with a wall element that can occupy a first position and a second position. In the first position, air from the second channel 107 is released into the opening 160, while in the second position, the wall element 189 blocks air from entering the opening 160.

[0251] In the illustrated embodiment, a wall element associated with the closure device 185 is configured at the adapter device 186. When the adapter device 186 is connected to the connection device 184 as intended, the air inlet opening 160 of the second channel 108 is blocked and / or closed by means of the wall element 189 of the adapter device 186. The wall element 189 is then arranged, for example, in the inner chamber 70 of the suction head housing 68 and / or covers the air inlet opening 160 (second positioning of the wall element 189).

[0252] When the adapter device 186 is separated from the connecting device 184, air is released into the opening 160 (the first positioning of the wall element 189).

[0253] The wall element 189 has, for example, a column shape and / or defines an airflow space 187 formed in the adapter device 186.

[0254] The connecting device 184 for the first air outlet 102 is configured in particular to be the same as the connecting device 36 for the suction connection end 34, so that, for example, the tubular element 186a can also be fluidly and releasably connected to the connecting device 36 for the suction connection end 34 by means of the adapter device 186.

[0255] The midpoint 190 and / or center of gravity of the exhaust fan device 22 are arranged on the first side 194 about the extension of the suction device 10 through the central plane 192 of the longitudinal central axis 28. The connecting channel 166 is substantially arranged on the second side 196, wherein the second side 196 is opposite the first side 194 about the central plane 192.

[0256] The first air outlet 102 is arranged on the second side 196 about the central plane 192, and the second air outlet 104 is arranged on the first side 194 about the central plane 192.

[0257] The suction device 10 has a gripping bow-shaped member 202 pivotally supported at the suction head 20, the gripping bow-shaped member being arranged about 32 about height in the end region 204 of the suction device 10 and / or the suction head 20. The gripping bow-shaped member 202 is configured, for example, as a U-shape.

[0258] The gripping bow-shaped part 202 can be moved from the first position 203a (see) Figure 2 Pivot to the second position 203b (see also) Figure 1 In the first position 203a, the gripping bow-shaped member 202 is oriented approximately horizontally in the operating state when the suction device 10 is positioned as specified. In the second position 203b, the gripping bow-shaped member 202 is oriented approximately vertically.

[0259] When the gripping bow-shaped member is in the first position 203a, the gripping bow-shaped member 202 forms, in particular, at least in sections, the outer contour of the suction head housing 68.

[0260] In the illustrated embodiment, the gripping bow-shaped member 202 is oriented at least approximately parallel to the upper side 78 of the cover element 76 in the first position 203a.

[0261] The gripping bow-shaped member 202 is located, for example, at least approximately, in the central plane (not shown) of the longitudinal central axis 28 extending through the suction device 10 in the second position 203b.

[0262] When the gripping bow 202 is in the first position 203a, the region 205 above the gripping bow 202 is at least approximately at the height of the upper side 78 with respect to the height direction 32.

[0263] The gripping bow-shaped member 202 has a first leg element 206 and a second leg element 208, wherein the first leg element 206 and the second leg element 208 are connected to each other by means of the gripping element 210.

[0264] The first leg element 206 and the second leg element 208 are respectively connected to the suction head housing 68 by means of a pivot hinge 212. The pivot hinge 212 is arranged in the end region 204 above the suction head 20.

[0265] The first leg element 206 is pivotally connected to the suction head 20, for example by means of a first pivot hinge 212a, and the second leg element 208 is pivotally connected to the suction head 20 by means of a second pivot hinge 212b.

[0266] The pivot hinge 212 is arranged in the outer region 214 and / or edge region of the suction head housing 68 with respect to a lateral direction 174 in a plane oriented transversely to and particularly perpendicular to the longitudinal central axis 28. The pivot hinge 212 is located at least approximately in a central plane (not shown) extending through the longitudinal central axis 28.

[0267] The outer region 214 and / or edge region refers to the area located outside the suction head housing 68 with reference to the direction oriented transversely to and in particular perpendicular to the longitudinal central axis 28.

[0268] To maintain the device 92, a spatial receiving area 216 is provided, which is constructed at the outer side 218 of the suction head housing 68. When the gripping bow 202 is in the first position 203a, the gripping bow 202 is adjacent to and / or defines the boundary of the receiving area 216.

[0269] The outer side 218 refers to the side of the suction head housing 68 and / or the suction head 20 that faces away from the inner chamber 70. The outer side 218 is especially the side facing the operator of the suction device 10.

[0270] The retaining device 92 and the receiving area 216 are arranged about height 32 between the channel device 96 and the cover element 76.

[0271] The retaining device 92 and the receiving area 216 are particularly provided and constructed for retaining the cable 94 and / or partially receiving the cable 94, for example, in a coiled state.

[0272] The gripping bow-shaped member 202 surrounds the cover element 76 in a U-shape and / or semi-circular manner in the first position 203a. The cover element 76 is further inward than the gripping bow-shaped member 202 in the lateral direction 174.

[0273] The gripping bow-shaped member 202 is, for example, adjacent to the cover element 76 in the first position 203a. The gripping element 210 is, for example, arranged on the second side 90 of the suction device 10 in the first position 203a.

[0274] The operator can pivot the gripping bow-shaped member 202 from the first position 203a to the second position 203b (and vice versa) using the gripping element 210. In the second position 203b, the gripping element 210 is arranged spaced apart from the upper side 78 of the suction head housing 68.

[0275] The handle element 210 can be grasped and / or held by the operator. The suction device 10 can be held and / or moved, for example, by grasping the gripping element 210.

[0276] When the gripping bow-shaped member 202 is in the first position 203a, the gripping element 210 for gripping the bow-shaped member 202 is provided with a spatial gripping area 220. The gripping element 210 can thus be gripped and / or held by the operator in the first position 203a. When the operator grips the gripping element 210 in the first position 203a, the gripping area 220 is particularly designed to accommodate the operator's hand and / or fingers.

[0277] The grasping region 220 is at least partially constructed within the receiving region 216.

[0278] Furthermore, the gripping region 220 extends at least partially between the gripping element 210 and the outer side 218 of the suction head housing 68. A segment of the gripping region 220 extends, for example, between the gripping element 210 and the wall element 221 of the cover element 76 facing the gripping element 210. This wall element 221 is oriented, for example, at least approximately parallel to or transverse to the longitudinal central axis 28 of the suction device 10.

[0279] When the gripping bow 202 is in the first position 203a, an upper opening 222 is formed between the gripping element 210 of the gripping bow 202 and the outer side 218 of the suction head housing 68. This upper opening 222 is accessible from above and / or is arranged at least approximately at the height of the upper side 78 of the cover element 76 with respect to the height direction 32.

[0280] Furthermore, when the gripping bow-shaped member 202 is in the first position 203a, a first lateral opening 224 and a second lateral opening 226 spaced circumferentially from the gripping element 210 and the outer side 218 are formed. The first lateral opening 224 and the second lateral opening 226 are arranged on the second side 90 of the suction device 10 and / or accessible from the second side 90 of the suction device 10. A holding device 92 is arranged between the first lateral opening 224 and the second lateral opening 226.

[0281] The first lateral opening 224 and the second lateral opening 226 extend in a plane that is transverse to and, in particular, perpendicular to the plane in which the upper opening 222 extends.

[0282] The first lateral opening 224 and the second lateral opening 226 extend between the bottom section 228, which defines the boundary of the receiving area 216, constructed on the outer side 218 of the suction head housing 68, and the gripping element 210 of the gripping bow 202.

[0283] The opening 222 at the top extends, for example, between the gripping element 210 and the wall element 221 of the cover element 76.

[0284] The bottom section 228 is constructed on the wall element 229 of the suction head housing 68, which is arranged in the height direction 32 between the channel device 96 and the receiving area 216. The retaining device 92 is arranged at the wall element 229.

[0285] When the gripping bow 202 is in the first position 203a, the receiving area 216 can be accessed by the operator's hand for gripping the gripping element 210 through the upper opening 222, the first lateral opening 224 and the second lateral opening 226.

[0286] A particularly flat abutment region 230 is constructed at the outer side 218 of the suction head housing 68, which at least segmentally adjacent to and / or gradually transitions into the receiving region 216. In the first position 203a, the gripping bow-shaped member 202 at least segmentally abuts against the abutment region 230.

[0287] The abutment area 230 is not necessarily configured to be spatially continuous. In the illustrated example, the abutment area 230 includes a first sub-region 230a for contacting the first leg element 206 of the gripping bow-shaped member 202 and a second sub-region 230b for contacting the second leg element 208. The first sub-region 230a and the second sub-region 230b are arranged, for example, opposite each other on the suction head housing. The first sub-region 230a and the second sub-region 230b are arranged on different sides and / or opposite sides of the cover element 76 of the suction head housing 68.

[0288] The abutment region 230 is located, for example, in a plane oriented transversely to and particularly perpendicular to the longitudinal central axis 28. The abutment region 230 extends between the pivot hinge 212 and the receiving region 216 in the outer region 214 and / or edge region of the suction head housing 68.

[0289] The abutment area 230 and / or the first sub-region 230a and / or the second sub-region 230b gradually transform into a transverse segment 232 forming the boundary of the defining receiving area 216 at the outer side 218. This transverse segment 232 is oriented transversely to the abutment area 230 and / or the bottom segment 228. The transverse segment 232 is arranged between the bottom segment 228 and the abutment area 230.

[0290] The smallest angle between the horizontal segment 232 and the bottom segment 228 is, for example, about 65°.

[0291] The retaining device 92 and the associated receiving area 216 are configured to be at least approximately mirror-symmetric about a plane, for example, about a central plane 192 extending through the longitudinal central axis 28.

[0292] The retaining device 92 and the associated receiving area 216 are arranged about lateral direction 174 in the outer region 214 and / or edge region of the suction head housing 68, wherein the retaining device 92 is arranged at the outer contour 234 of the suction head housing 68.

[0293] The outer contour 234 is an external boundary line and / or interface at the suction head housing 68 with respect to the transverse direction 174, which is oriented, for example, in the circumferential direction 100. The outer contour 234 has, for example, at least approximately a constant curvature and / or a constant radius of curvature.

[0294] The outer contour 234 extends, for example, through the outer side 235 of the suction head housing 68 located in the outer region 214 and / or edge region, which is adjacent to the receiving region 216 in the circumferential direction 100.

[0295] The accommodating area 216 is constructed as a concave section about the outer contour 234.

[0296] The receiving area 216 extends inward from the outer contour 234 and / or from the retaining device 92 (towards the cover element 76 and / or the longitudinal central axis 28).

[0297] The retaining device 92 extends in the height direction 32 from the lower end 236 to the upper end 238 of the receiving area 216. The bottom section 228 is disposed, for example, at the height of the lower end 236, and the lateral section 232 extends between the lower end 236 and the upper end 238.

[0298] The retaining device 92 is configured, for example, as a hook element 239 or includes a hook element 239.

[0299] The retaining device 92 includes a second region 240 disposed in the upper end region 242 of the retaining device 92. The second region 240 is connected to a first region 244 of the retaining device 92, wherein the first region 244 is connected to the suction head housing 68.

[0300] The second region 240 is connected to the first region 244, for example, by means of a screw-on connection. The first region 244 is integrally connected to the suction head housing 68, for example.

[0301] The second region 240 protrudes from the first region in the lateral direction 174. For example, the second region 240 protrudes from the first region 244 in the lateral direction 174 toward the cover element 76 and / or the longitudinal central axis 28.

[0302] The retaining device 92 has a width B1, wherein the width direction is oriented in the circumferential direction 100 of the suction head housing 68. The width B1 is greatest at the lower end 246 of the retaining device 92 and smallest at the upper end 248 of the retaining device 92.

[0303] The lower end 246 is located at the height of the lower end 236 of the receiving area 216 and the upper end 248 is located at the height of the upper end 238 of the receiving area 216.

[0304] The retaining device 92 has an upper end side 250 that is oriented at least approximately parallel to the abutment region 230. The upper end side is, for example, at least approximately at the height of the abutment region 230 with respect to the height direction 32. The abutment region 230 and the upper end side 250 are, for example, at least approximately in the same plane.

[0305] When the gripping bow 202 is in the first position 203a, the gripping element 210 of the gripping bow 202 rests against, for example, the upper end side 250. The upper end side 250 forms, for example, an abutment area for gripping the bow 202 and / or the gripping element 210.

[0306] The retaining device 92 has an outer side 252 that is opposite to the receiving area 216 and / or the longitudinal central axis 28. This outer side 252 is located, for example, in the outer contour 234.

[0307] It can be specified that a locking device 254 is provided for the gripping bow-shaped member 202, by means of which the gripping bow-shaped member 202 can be fixed and / or snapped into and / or locked in the first position 203a. For example, the gripping bow-shaped member 202 can be fixed and / or snapped into and / or locked in the first position 203a at the retaining device 92 by means of the locking device 254.

[0308] In one embodiment, a spring device 256 is provided for the gripping bow-shaped member 202, by means of which the gripping bow-shaped member 202 can be switched from a first position 203a to a second position 203b in the direction of or opposite to the spring force applied by the spring device 256. The spring device 256 is arranged or constructed, for example, at at least one pivot hinge in the pivot hinge 212.

[0309] The first pivot hinge 212a includes a journal element 258, which is arranged and / or constructed at the first leg element 206. This journal element 258 extends from the first leg element 206 in a direction toward the cover element 76 of the suction head 20 when the gripping bow 202 is positioned as intended at the suction device 10. The journal element 258 may project, for example, from the first leg element 206 in the direction of the cover element 76.

[0310] The first pivot hinge 212a and / or journal element 258 are arranged, for example, at the end 259 of the cover element 76 and / or at the end region of the gripping bow 202.

[0311] Furthermore, the first pivot hinge 212a includes a sleeve element 260 for rotatably supporting the journal element 258. The journal element 258 can be received by means of the sleeve element 260 and / or the journal element 258 can be retracted into the sleeve element 260.

[0312] The journal element 258 can be arranged on the sleeve element 260 and / or can be inserted into the sleeve element 260 toward the cover element 76.

[0313] Sleeve element 260 is arranged and / or constructed at cover element 76. Sleeve element 260 is configured, for example, as a recess in the wall element 262 of cover element 76 facing the first leg element 206 and / or journal element 258.

[0314] When the gripping bow 202 is in the first position 203a, the wall element 221 facing the gripping element 210 is connected to the wall element 262, for example, in the circumferential direction 100.

[0315] The first pivot hinge 212a is constructed in the illustrated embodiment to be identical to the second pivot hinge 212b.

[0316] The gripping bow 202 is pivotable about a pivot axis 264 and / or a rotation axis by means of a first pivot hinge 212a and / or a second pivot hinge 212b, which is oriented, for example, transverse to or particularly perpendicular to the longitudinal centerline 28 and / or the height direction 32.

[0317] In one embodiment, a limiting element 266 is provided associated with the first pivot hinge 212a, which, when the gripping bow-shaped member 202 is in the second position 203b, prevents the movement of the first leg member 206 in the direction away from the cover member 76. Correspondingly, a limiting element 266 may be provided associated with the second pivot hinge 212b.

[0318] In the illustrated example, the limiting element 266 is arranged at the suction head 20, spaced apart from the cover element 76 and / or from the sleeve element 260. The limiting element 266 is arranged in the region located at the pivot hinge 212a.

[0319] The limiting element 266 is, for example, arranged at the first sub-region 230a of the abutment region 230. The limiting element 266 is, for example, configured as a protrusion.

[0320] The gripping bow-shaped member 202 includes a wall element 268 facing the interior of the cover element 76 and a wall element 270 facing away from the exterior of the cover element 76. The journal element 258 is particularly arranged at the interior wall element 268.

[0321] A gap 272 is provided between the inner wall element 268 and the outer wall element 270, which opens particularly toward the lower side 274 of the gripping bow 202, wherein the lower side 274 faces the abutment area 230 when the gripping bow 202 is in the first position 203a.

[0322] One or more rib elements 276 are arranged in the gap 272, for example, between the inner wall element 268 and the outer wall element 270. The rib elements 276 are oriented, for example, transverse to and particularly perpendicular to the inner wall element 268 and / or the outer wall element 270.

[0323] The clearance element 266 is arranged in at least sections in the gap 272 and / or at least in sections between the inner wall element 268 and the outer wall element 270.

[0324] When the gripping bow-shaped member 202 is in the second position 203b, the limiting element 266 is arranged between the outer wall element 270 and the stop element 278. When the gripping bow-shaped member 202 is in the second position, this stop element 278 can abut against the limiting element 266 and thereby prevent the first leg element 206 from moving away from the cover element 76 in one direction.

[0325] When the gripping bow-shaped member 202 is in the second position, the first leg member 206 is prevented from moving away from the cover member 76 by the cooperation of the limiting element 266 and the stop element 278. This prevents the journal element 258 from moving out of the sleeve element 260 in the second position 203b.

[0326] The stop element 278 can pivot and / or rotate relative to the limiting element about the pivot axis 267, so that the gripping bow 202 can move from the second position 203b to the first position 203a.

[0327] A stop element 278 is arranged, for example, in the gap 272 between the outer wall element 270 and the inner wall element 268. The stop element 278 is arranged, for example, on a rib element 276a, which is oriented transversely and, in particular, perpendicularly to the inner wall element 268 and / or the outer wall element 270. The stop element 278 is oriented, for example, transversely and, in particular, perpendicularly to the rib element 276a.

[0328] It can be specified that a groove 280 is constructed at the rib element 276a, wherein when the gripping bow-shaped member 202 moves from the second position 203b to the first position 203a, the limiting element 266 can be guided or is guided through the groove 280 in at least a segment.

[0329] In the first position 203a, the limiting element 266 and the stop element 278 are arranged spaced apart. The stop element 278 can then move relative to the limiting element 266, particularly without being obstructed by the limiting element 266. The gripping bow-shaped member 202 can move in the first position 203a, for example, between a first positioning where the limiting element 266 abuts against the outer wall element 270 and a second positioning where the limiting element 266 abuts against the inner wall element 268 (see...). Figure 14 and 15 ).

[0330] In the first positioning, the journal element 268 is arranged within the sleeve element 260. In the second positioning, the journal element 258 is arranged outside the sleeve element 260. This allows the gripping bow-shaped member 202 to be installed and / or removed from the suction head 20 in the first position 203a without tools.

[0331] The suction device according to the present invention operates as follows:

[0332] To perform a suction process using the suction device 10, the operator connects, for example, the suction hose of the suction device 10 to the suction connection end 34. The operator then turns on the suction device 10, for example, via the operating element device 82. The respective parameters of the suction process can be controlled by the operator, for example, via the operating element device 82.

[0333] The (dirty) process air is coupled into the containment space 14 of the suction container 12 through the suction connection terminal 34 by the exhaust fan device 22.

[0334] The dirty portion of the process air coupled in is discharged into the containment space 14 of the suction container 12 and / or discharged to the dirty side 64 of the filter unit 56.

[0335] Clean process air is coupled into the exhaust fan unit 22 through the clean side 60 of the filter unit 56. This process air is then coupled out from the suction head 20 through the first air outlet 102 and the second air outlet 104 via the channel device 96.

[0336] To empty the suction container 12, the retaining device 52 is opened and the suction head 20 is then lifted upward from the suction container 12 by means of the gripping bow 202. For this purpose, the gripping bow 202 is moved to the second position 203b by the operator. After emptying the suction container 12, the suction head 20 is reattached to the suction container 12 by means of the gripping bow 202 and secured to the suction container by the retaining device 52.

[0337] In order to perform the blowing process using the suction device 10, the suction hose is connected to the connection device 184 of the first air outlet 102 via the adapter device 186.

[0338] Therefore, the sealing device 185 transitions from the first state to the second state, thus preventing process air from being coupled out of the suction head 20 through the second air outlet 104. The coupled out of the process air is then accomplished through the first air outlet 102, and in particular, solely through the first air outlet 102.

[0339] Process air is thus coupled into the suction hose and coupled out again at one end of the suction hose, so that the operator can use the blowing function via the suction hose.

[0340] To store the suction device 10, the suction hose is, for example, disconnected from the suction connection end 34 and / or the connection device 184. The suction hose can be secured and / or stored at the suction head 20, for example, by means of the retaining element 79.

[0341] The cable 94 of the suction device 10 can be held and / or stored at the suction head 20 by means of the retaining device 92 and the receiving area 216 associated with the retaining device 92.

[0342] To position the cable 94 within the receiving area 216, the operator shifts the gripping bow 202 to the second position 203b, thus allowing the receiving area 216 to be accessed from above at the suction head 20 (see example). Figure 1 In this state, cable 94 is arranged in receiving area 216 and there, for example, rolled up and / or arranged as coiled wire.

[0343] The operator then moves the gripping bow 202, for example, to a first position 203a, so that the gripping bow 202 is adjacent to the receiving area 216. In this position of the gripping bow 202, the cable 94 arranged in the receiving area 216 moves in an upward direction and outward in the lateral direction 174 (see example). Figure 2 ).

[0344] To remove cable 94 from receiving area 216, the operator moves the gripping bow-shaped piece from first position 203a to second position 203b, thus allowing cable 94 to be pulled upwards from receiving area 216 (see example). Figure 1 ).

[0345] To disassemble the gripping bow member 202 without tools, shift the gripping bow member into the first position 203a. The operator presses the first leg element 206 outwards away from the cover element 76 until the limiting element 266 abuts against the inner wall element 268 and / or until the journal element 258 is removed from the sleeve element 260 (see...). Figure 15 Immediately following, the first leg element 206 can move upward away from the suction head as the journal element 258 disengages. As the first leg element 206 is pulled out, the operation is repeated accordingly with the second leg element 208, thus releasing the gripping bow-shaped member 202 from the suction head 20. For tool-free installation, the steps are performed in reverse order.
