Description

[0001] The present invention relates to a suction device with a filter cleaning device according to the preamble of claim 1. State of the art

[0002] A vacuum cleaner with a filter cleaning system is already known from EP 1 839 550 A2. Disclosure of the invention

[0003] The invention is based on a suction device with a suction device housing, with a filter for cleaning a suction flow, in particular within the suction device housing, wherein the suction device housing has at least one filter fastening element for at least indirectly fastening the filter to the suction device housing, and with a filter cleaning device for mechanically cleaning the filter, wherein the filter, the filter fastening element and the filter cleaning device are arranged at least partially within the suction device housing.It is proposed that the filter cleaning device comprises an actuating device, in particular a manually actuated one, and a hammer device, wherein the actuating device and the hammer device interact in such a way that the hammer device can be actuated using the actuating device, in particular manually, and the hammer device exerts at least one impulse on the filter fastening element upon actuation.

[0004] The invention provides a suction device with which the service life of the suction device can be increased by the hammer device exerting at least one impulse on the filter fastening element.

[0005] A "vacuum cleaner" is an electrical device designed to generate a suction current to suck up dust and / or dirt particles and / or liquids. For example, the vacuum cleaner can be designed as a vacuum cleaner.

[0006] In one embodiment, the vacuum cleaner is a battery-operated vacuum cleaner that can be operated by at least one battery, in particular by a handheld power tool battery pack. This then provides electrical energy by supplying power to the vacuum cleaner via the at least one battery. Within the context of the present invention, a "handheld power tool battery pack" is understood to mean a combination of at least one battery cell and a battery pack housing. The handheld power tool battery pack is advantageously designed to supply power to commercially available battery-operated handheld power tools.

[0007] The vacuum cleaner housing is intended at least to accommodate at least the filter fastening element and the filter cleaning device. The filter fastening element and / or the filter cleaning device can be arranged on the vacuum cleaner housing and connected to the vacuum cleaner housing in a form-fitting, force-fitting, and / or material-fitting manner. The vacuum cleaner housing can be formed in one piece, two pieces, or multiple pieces. For example, the vacuum cleaner housing can comprise at least two housing parts, which are designed like a pot with a lid or like a sunny side and a shady side. In one embodiment, the vacuum cleaner housing can comprise an upper housing part and a dust collection container. The upper housing part and the dust collection container can be detachably connected to one another.The upper housing section can comprise an electric motor, a control unit for controlling the suction device, and the power supply for supplying the suction device with electrical energy. Furthermore, the suction device housing can comprise at least one suction device axis. The suction device housing can be designed to be substantially rotationally symmetrical about the suction device axis. For example, the suction device housing can be shaped like a cylinder, a cone, or a truncated cone.

[0008] The electric motor can drive the vacuum cleaner as soon as the electric motor is supplied with electrical energy from the power supply. When the electric motor is supplied with electrical energy, it can generate at least one suction flow substantially through the vacuum cleaner housing. A suction flow here refers to an airflow substantially through the vacuum cleaner housing via at least one vacuum cleaner housing inlet and from at least one vacuum cleaner housing outlet, whereby it is also conceivable that the suction flow can be generated substantially through the vacuum cleaner housing by means of a suction effect. By generating the suction flow, particles and / or liquids can be sucked in and / or drawn in, for example via a suction hose of the vacuum cleaner. A suction hose has at least one suction opening and is preferably detachably attachable to the vacuum cleaner housing.The suction opening is designed to collect particles generated by the suction flow during operation of the suction device.

[0009] The filter is designed to filter the suction flow of material and / or fluid particles, thus cleaning the suction flow. The filter can be arranged within the vacuum cleaner housing. In the exemplary two-part design of the vacuum cleaner housing described above, the filter can be arranged on the upper part of the housing and extend into the dust collection container.

[0010] The vacuum cleaner housing has the filter fastening element for at least indirectly fastening the filter to the vacuum cleaner housing. This allows the filter to be at least indirectly connected, in particular detachably, to the vacuum cleaner housing. The at least indirect connection of the filter to the vacuum cleaner housing can, for example, be a screw connection, a clamp connection, a snap connection, a hook connection, or a bayonet connection. For example, the bayonet connection can realize both an easy-to-use and secure at least indirect connection of the filter to the vacuum cleaner housing. In the exemplary two-part implementation of the vacuum cleaner housing described above, the filter fastening element can arrange the filter on the upper housing part such that the filter protrudes into the dust collection container.The filter fastening element can be formed, for example, as a filter fastening ring, a filter fastening groove, a filter fastening rail, a filter fastening edge, a filter fastening hook, a T-shaped filter fastening profile, a filter fastening shell, a filter fastening pot or the like.

[0011] The filter cleaning device is designed to mechanically clean the filter. "Mechanical cleaning" is understood here as cleaning the filter essentially without the use of electrical energy from the power supply and without the use of chemicals. By applying an impulse to the filter fastening element, at least one vibration in the form of structure-borne sound can be introduced into the vacuum cleaner housing. The at least one vibration can then be transmitted to the filter via the filter fastening element, so that dust and / or dirt particles can be released from the filter due to the at least one vibration. The filter cleaning device essentially cleans the filter of dust and / or dirt particles as well as liquids that have accumulated in and / or on the filter during its use. The filter cleaning device is arranged at least partially within the vacuum cleaner housing.In the exemplary two-part implementation of the vacuum cleaner housing described above, the filter cleaning device can be arranged on the upper housing part and / or on the dust collection container. Furthermore, the filter cleaning device can be connected to the upper housing part or the dust collection container.

[0012] The filter cleaning device comprises the actuating device, which can be operated manually, and the hammer device. In the exemplary two-part implementation of the vacuum cleaner housing described above, the actuating device and / or the hammer device can be arranged on the upper housing part and / or the dust collection container. In this exemplary embodiment, it is also conceivable for the actuating device and / or the hammer device to be arranged within the upper housing part and / or the dust collection container. The actuating device is designed such that it can be operated manually by a user. Within the scope of the present invention, "manually operable" is to be understood as an actuation, in particular a mechanical one, essentially without the use of electrical energy from the power supply.In this case, the actuation of the actuating device by the user can, for example, be a pressing, pushing, pulling or turning of the actuating device.

[0013] The actuating device interacts with the hammer device in such a way that as soon as the user actuates the actuating device, the actuating device actuates the hammer device.

[0014] The actuating device is designed to actuate the hammer device, in particular manually, as soon as the user actuates the actuating device. As described above, "manual actuation" should also be understood here as an actuation, in particular a mechanical actuation, essentially without the use of electrical energy. The actuating device can, for example, press, push, slide, tilt, pivot, rotate, or pull the hammer device. Actuating the hammer device by means of the actuating device can be understood as a type of "activation" or "pretensioning" and subsequent "triggering." Once the actuating device has actuated the hammer device, the hammer device can thus exert the impulse on the filter fastening element.In the above-mentioned exemplary embodiment of the vacuum cleaner with a vacuum cleaner axis, the hammer device can exert the impulse on the filter fastening element axially to the vacuum cleaner axis, radially to the vacuum cleaner axis, or transversely to the vacuum cleaner axis. "Axially to the vacuum cleaner axis" is understood as parallel to the vacuum cleaner axis. "Radially to the vacuum cleaner axis" is understood as perpendicular to the vacuum cleaner axis. "Transversely to the vacuum cleaner axis" is understood as obliquely, including at least an angle in the range of 1° to 89°. Furthermore, the hammer device can exert the impulse directly or indirectly on the filter fastening element. "Directly" is understood here as exerting it directly on the filter fastening element. "Indirectly" is understood here as exerting it indirectly, via at least one other component or element, on the filter fastening element.For example, the hammer device can apply the impulse in the form of structure-borne sound to the filter via the filter mounting element. For this purpose, the structure-borne sound can be transmitted from the hammer device to the filter mounting element via the suction device housing, in particular the upper housing section.

[0015] By activating the actuating device, the hammer mechanism is mechanically activated and triggered, exerting an impulse on the filter. As a result of the impulse, the filter is freed of any dust and / or dirt particles accumulated in and / or on it. Due to the impulse, the dust and / or dirt particles can detach from the filter and fall, for example, into the dust collection container.

[0016] The vacuum cleaner housing has at least one cover, in particular a cover of a power supply coupling means, wherein the cover is pivotable about a cover pivot axis from a first position of the cover to a second position of the cover, and the cover actuates the filter cleaning device, in particular the actuating device, upon movement from the first position of the cover to the second position of the cover. The cover of the vacuum cleaner housing can be at least positively connected to the vacuum cleaner housing. The cover of the vacuum cleaner housing is designed to at least partially close at least part of the vacuum cleaner housing. In the exemplary two-part implementation of the vacuum cleaner housing described above, the cover of the vacuum cleaner housing can close at least part of the housing upper part and / or the dust collection container.The lid of the vacuum cleaner housing can close the vacuum cleaner housing in such a way that dust and / or dirt particles and / or liquids are prevented from entering the vacuum cleaner housing, in particular, they are prevented from entering. The lid of the vacuum cleaner housing can be shaped, for example, like a flap, a bowl, a half-shell, or a pot.

[0017] The lid can be pivoted from the first position of the lid to the second position of the lid about the lid pivot axis. The first position of the lid can be an open position of the lid, in which at least part of the suction device housing can be open. The second position of the lid can be a closed position in which the lid is in particular form-fitting engagement with the suction device housing, in particular the upper housing part. In the above-mentioned exemplary embodiment of the suction device with a suction device axis, the lid pivot axis can be arranged transversely, in particular perpendicularly, to the suction device axis, so that the suction device axis and the lid pivot axis intersect at at least one point. It is also conceivable that the lid pivot axis and the suction device axis are essentially parallel or skewed to one another."Substantially parallel" should be understood here to mean that an angle in the range of 1° to 10° can exist between the lid pivot axis and the suction device axis. The suction device housing, in particular the upper housing section, can have a receptacle for accommodating the lid pivot axis. The lid can be pivotably mounted using the receptacle for the lid pivot axis.

[0018] In the context of the present invention, "pivoting" is understood as an at least partial rotation of the lid of the vacuum cleaner housing about the lid pivot axis, wherein the lid pivot axis is formed decentrally, particularly at the end, on the lid of the vacuum cleaner housing. The lid can be pivoted by the user about the lid pivot axis from the first, particularly open, position of the lid to the second, particularly closed, position of the lid.

[0019] During the movement, in particular pivoting movement, of the lid of the vacuum cleaner housing about the lid pivot axis from the first position of the lid to the second position of the lid, the filter cleaning device, in particular the actuating device, is actuated. For this purpose, the lid can be connected to the filter cleaning device in a form-fitting, force-fitting, and / or material-fitting manner in order to convert the pivoting movement into the actuation of the filter cleaning device. It is also conceivable for the lid to actuate the filter cleaning device during the movement, in particular pivoting movement, from the second position of the lid to the first position of the lid.

[0020] The cover and / or the filter cleaning device can have at least one spring element designed to move, in particular pivot, the cover from the second position of the cover to the first position of the cover. The spring element can be arranged circumferentially around the cover pivot axis. The spring element can be configured, for example, as a spring, a coil spring, or a leaf spring.

[0021] The cover can be the cover of a power supply coupling means. The power supply coupling means is designed to accommodate the battery, in particular the handheld power tool battery pack, and to mechanically and electrically connect it to the power supply. The power supply coupling means is arranged on the vacuum cleaner housing, in particular on the upper housing part, and is connected thereto. The cover of the power supply coupling means is designed to cover, in particular to close, the power supply coupling means in order to avoid, in particular to prevent, the penetration of dust and / or dirt particles and / or liquid to the power supply coupling means. The cover of the power supply coupling means can be designed, for example, as a flap, a shell, a half-shell, or a pot.

[0022] In one embodiment of the suction device, the lid has at least one receiving element and the actuating device comprises at least one connecting element and / or the lid has at least one connecting element and the actuating device comprises at least one receiving element, wherein the receiving element is connectable or connected to the connecting element, in particular rigidly. The receiving element can receive the connecting element. In this case, the receiving element can enable at least one positive, non-positive and / or material-locking connection with the connecting element. The positive, non-positive and / or material-locking connection of the connecting element to the receiving element enables the movement, in particular the pivoting movement, to be transmitted or transferred from the lid to the actuating device.The positive, non-positive, and / or material connection between the receiving element and the connecting element can be designed, for example, as a hook connection, a tongue-and-groove connection, a snap connection, a bayonet connection, a locking connection, or a screw connection by means of at least one fastening element such as a screw. The cover and the actuating device can be rigidly connected to one another in such a way that the cover can transmit a lever effect to the actuating device.

[0023] The receiving element can be formed as a receptacle. The receptacle can be shaped, for example, as an opening, a recess, or in the manner of a bowl or pot. The connecting element can be designed, for example, as a tenon, a pin, a hook, a web, an edge, or a bolt.

[0024] In one embodiment of the suction device, the actuating device has at least one actuating element, wherein the actuating element is pivotably mounted about an actuating axis from a first position of the actuating device to a second position of the actuating device, and the actuating element actuates the hammer device upon pivoting. The actuating element is designed to actuate the hammer device. In the above-mentioned exemplary embodiment of the suction device with a suction device axis, the actuating axis can be arranged transversely, in particular perpendicularly, to the suction device axis. Furthermore, the actuating axis can be substantially parallel to the lid pivot axis. Preferably, the lid pivot axis and the actuating axis can be coaxial with one another. The suction device housing, in particular the upper housing part, can have a receptacle for receiving the actuating axis.The actuating element can be pivoted using the actuating axis holder.

[0025] In the first position of the actuating device, the actuating element can rest against the hammer device or have essentially no connection with the hammer device. During the pivoting movement of the actuating element from the first position of the actuating device to the second position of the actuating device, the actuating element actuates the hammer device. The actuating element rests against the hammer device and pivots the hammer device. In the second position of the actuating device, the actuating element can rest against the hammer device or be spaced apart from the hammer device.

[0026] It is conceivable that when the actuating device is in its first position, the lid is in its first position. It is also conceivable that when the actuating device is in its second position, the lid is in its second position. This makes it conceivable that when the lid is pivoted from the first position of the lid to the second position of the lid, the actuating device is pivoted from the first position of the actuating device to the second position of the actuating device.

[0027] It is possible for the actuating element to actuate the hammer device when pivoting from the second position of the actuating device to the first position of the actuating device. In the above-mentioned exemplary embodiment of the suction device with a suction device axis, it is also conceivable for the actuating axis to be arranged substantially parallel or skewed to the suction device axis.

[0028] The actuating element can, for example, be shaped like a pin, a web, a blade, a rod, a hook, a pin, a roller, a spring, or a lug. The actuating element can be integral with the receiving element or the connecting element.

[0029] In one embodiment of the suction device, the actuating device has at least one pivoting element, and the actuating element comprises at least one guide element. The guide element is designed to guide the pivoting element, in particular to keep it aligned, during pivoting from a first position of the pivoting element to a second position of the pivoting element. The pivoting element actuates the hammer device using the actuating element. The pivoting element is designed such that it is pivotably mounted about the actuating axis. The pivoting element is arranged on the actuating element. In the first position of the pivoting element, the pivoting element can be substantially parallel to the actuating element and / or the guide element. In addition, in the first position of the pivoting element, the pivoting element can bear against the hammer device or be at a distance from the hammer device.When the pivoting element is pivoted from the first position of the pivoting element to the second position of the pivoting element using the guide element, the pivoting element actuates the hammer device. In the second position of the pivoting element, the pivoting element can bear against the hammer device or be spaced apart from the hammer device. Furthermore, in the second position of the pivoting element, the pivoting element can be substantially parallel to the actuating element and / or the guide element. The guide element can keep the pivoting element aligned with respect to the actuating axis during the pivoting movement.

[0030] The guide element can be connected to the actuating element in a form-fitting, force-fitting, and / or material-fitting manner. It is also possible for the guide element and the actuating element to be integral. The guide element is designed such that it guides the pivoting element during pivoting from the first position of the pivoting element to the second position of the pivoting element. For this purpose, the pivoting element rests at least partially against the guide element. As soon as the actuating element is pivoted, the guide element can be pivoted.

[0031] The pivoting element can be arranged on the actuating element such that, when the actuating element is in the first position of the actuating device, the pivoting element can be in the first position of the pivoting element. Furthermore, the pivoting element can be in the second position of the pivoting element when the actuating element is in the second position of the actuating device.

[0032] It is also conceivable that the guide element guides the pivoting element from the second position of the pivoting element to the first position of the pivoting element and thereby actuates the hammer device.

[0033] The pivoting element can be designed, for example, in the form of a cylinder, a cube, a cuboid, a sphere with a web, a roller, or the like. The pivoting element can, for example, have a U-shaped, V-shaped, L-shaped, T-shaped, or I-shaped form. The guide element can, for example, be designed as a guide track, a guide surface, a guide web, a guide slot, or a guide groove.

[0034] In one embodiment, the actuating element, the guide element, and the connecting element of the actuating device are formed as a single piece. In an alternative embodiment, the actuating element, the guide element, and the receiving element of the actuating device are formed as a single piece.

[0035] In one embodiment of the suction device, the pivoting element is connected to the actuating element via at least one actuating joint. An actuating joint is a movable connection between the pivoting element and the actuating element. The actuating element can have at least a first receptacle and a second receptacle. The first receptacle of the actuating element can be designed as a receptacle for a pin. The first receptacle of the actuating element can be formed as at least one through-opening. It is conceivable for the first receptacle of the actuating element to be designed as at least one pin, wherein the pin at least partially accommodates the pivoting element. The second receptacle of the actuating element can accommodate the pivoting element at least in sections by the second receptacle of the actuating element engaging in the pivoting element.

[0036] The pivoting element can have at least a first receptacle and a second receptacle. The first receptacle of the pivoting element can be designed as at least one receptacle for a pin. For example, the first receptacle of the pivoting element can be formed as at least one through-opening. The second receptacle of the pivoting element can be designed as a recess, wherein the recess can at least partially accommodate the second receptacle of the actuating element.

[0037] The actuating joint is designed to pivotally mount the pivoting element relative to the actuating element. The first receptacle of the actuating element, the first receptacle of the pivoting element, and at least one pin form the actuating joint. The pin can connect the first receptacle of the actuating element and the first receptacle of the pivoting element.

[0038] In one embodiment of the suction device, the pivoting element has at least one return element, wherein the return element is designed to return the pivoting element from a second relative position of the pivoting element to a first relative position of the pivoting element. The return element can be connected to the pivoting element in a form-fitting, force-fitting and / or material-fitting manner. It is conceivable for the return element to be integral with the pivoting element. The pivoting element can have a receptacle for the return element, wherein the receptacle for the return element can be formed as a through-opening. The return element can be shaped in the form of a rod, a pin, a roller, a sheet, a cube, a cuboid, a prism or the like, or in the form of a spring element, such as a spring, a spiral spring or a leaf spring.The return element can have a mass in order to return the pivoting element from the second relative position of the pivoting element to the first relative position of the pivoting element by means of a weight force of the mass of the return element.

[0039] The first relative position of the pivot element characterizes a substantially parallel arrangement of the pivot element relative to the actuating element. The second relative position of the pivot element characterizes an angular arrangement of the pivot element relative to the actuating element. The pivot element can enclose an angle in the range of 1° to 179° relative to the actuating element.

[0040] When the pivoting element is pivoted from the first position of the pivoting element to the second position of the pivoting element, the pivoting element is held aligned in the first relative position of the pivoting element by the guide element. Once the pivoting element is pivoted from the second position of the pivoting element to the first position of the pivoting element, the pivoting element can be arranged in the second relative position. When the pivoting element is arranged in the second relative position of the pivoting element, the return element enables the pivoting element to be returned to the first relative position. When the pivoting element is in the first relative position of the pivoting element, the pivoting element can be enabled to reliably actuate the hammer device when the actuating device is pivoted from the first position of the actuating device to the second position of the actuating device.The return element therefore enables the actuating device to actuate the hammer device again.

[0041] It is also conceivable that the return element returns the pivoting element from the second relative position of the pivoting element to the first relative position of the pivoting element when the pivoting element actuates the hammer device during the pivoting movement from the second position of the pivoting element to the first position of the pivoting element.

[0042] In one embodiment of the suction device, the hammer device has at least one guide element, wherein the guide element of the hammer device interacts with the actuating device in such a way that the guide element, using the actuating device, pivots the hammer device from a first position of the hammer device to a second position of the hammer device about a hammer device axis. The actuating element and / or the pivoting element slides over the guide element of the hammer device and exerts pressure on the hammer device via the guide element of the hammer device. The guide element can be connected to the hammer device in a form-fitting, force-fitting and / or material-fitting manner. It is also conceivable for the guide element of the hammer device to be integral with the hammer device.The guide element can be formed, for example, as a guide track, a guide surface, a guide groove, a guide web, or as a guide slot. The guide element of the hammer device can at least partially accommodate the actuating device, in particular the actuating element or the pivoting element. The guide element of the hammer device can accommodate the actuating device in such a way that the guide element of the hammer device transmits the actuation by the actuating device to the hammer device. As a result, the pivoting movement of the actuating device, in particular of the actuating element or the pivoting element, can be transmitted from the first position of the actuating device to the second position of the actuating device.The guide element can guide the actuating device, in particular the actuating element and / or the pivoting element, in order to guide the hammer device from the first position of the hammer device to the second position of the hammer device.

[0043] In the first position of the hammer device, the hammer device can rest against the suction device housing, in particular against the upper housing part, and / or against the filter fastening element. In the second position of the hammer device, the hammer device can be at a distance from the suction device housing, in particular the upper housing part, and / or the filter fastening element. As soon as the actuating device is actuated from the first position of the actuating device to the second position of the actuating device, the hammer device is pivoted from the first position of the hammer device to the second position of the hammer device using the actuating element and / or pivoting element and the guide element of the hammer device. It is also conceivable for the actuating device to actuate the hammer device from the second position of the hammer device to the first position of the hammer device.

[0044] The hammer device axis can be arranged transversely, in particular perpendicularly, to the suction device axis of the exemplary two-part implementation of the suction device housing described above. It is conceivable for the hammer device axis to be skewed or substantially parallel to the suction device axis. Furthermore, the hammer device axis can be substantially parallel to the actuation axis. The suction device housing, in particular the upper housing part, can have a receptacle for receiving the hammer device axis. The hammer device can be pivotably mounted using the receptacle for the hammer device axis.

[0045] In one embodiment of the suction device, the hammer device has at least one return element, wherein the return element is arranged at least partially between the hammer device and the suction device housing, and the return element returns the hammer device about the hammer device axis from the second position of the hammer device to the first position of the hammer device. The return element can bear against the hammer device and / or the suction device housing, in particular the upper housing part. The return element can form a positive, non-positive and / or materially bonded connection with at least one element of the hammer device and / or the suction device housing, in particular the upper housing part. The return element of the hammer device can be designed as at least one mass, an elastic element and / or a spring element.The return element of the hammer device, as the mass, can return the hammer device from the second position of the hammer device to the first position of the hammer device by means of a weight force. The return element of the hammer device, as the mass, can be shaped, for example, in the form of a rod, a pin, a cube, a cuboid, a prism, or the like. The return element of the hammer device, as the elastic element, can be shaped, for example, as a rubber buffer. The return element of the hammer device, as the spring element, can be designed, for example, as a spring, a coil spring, or a leaf spring.

[0046] It is conceivable that the return element of the hammer device returns the hammer device from the first position of the hammer device to the second position of the hammer device.

[0047] In one embodiment of the suction device, the hammer device has at least one hammer element which is designed to transmit the impulse to the filter fastening element when the hammer device is pivoted about the hammer device axis from the second position of the hammer device to the first position of the hammer device. The hammer element can be connected to the hammer device in a form-fitting, force-fitting and / or material-fitting manner. In the first position of the hammer device, the hammer element can bear against the above-mentioned exemplary embodiment of the suction device, in particular against the upper housing part, and / or against the filter fastening element. In the second position of the hammer device, the hammer element can be spaced from the suction device housing, in particular the upper housing part, and / or the filter fastening element. The hammer element can be designed in the form of a mass.The hammer element as the mass may be in the form of a cube, a cuboid, a pin, a rod, a cylinder, a cone, a truncated cone, a pyramid, a truncated pyramid or the like.

[0048] When pivoting the hammer device from the second position of the hammer device to the first position of the hammer device, the hammer element can transmit the impulse to the filter fastening element using the return element of the hammer device. For this purpose, the hammer element can convert energy, in particular mechanical energy, into the impulse, wherein the energy, in particular mechanical energy, can be provided by the return element. The hammer element can transmit the impulse to the filter fastening element in the axial and / or radial direction relative to the suction device axis.

[0049] In one embodiment, the hammer device comprises a hammer housing, wherein the hammer housing accommodates at least the hammer device axis, the guide element of the hammer device, the receptacle for the return element of the hammer device, and the hammer element. The hammer housing, the guide element of the hammer device, and the receptacle for the return element of the hammer device can be formed integrally. The hammer housing can have a receptacle for the hammer element, wherein the hammer housing and the hammer element can be connected to one another in a form-fitting, force-fitting, and / or material-fitting manner.

[0050] The invention is explained below using a preferred embodiment. The drawings show: Fig. 1 a schematic view of a suction device according to the invention; Fig. 2 a perspective view of a base plate of the upper housing part with a filter cleaning device; Fig. 3 a perspective view of the filter cleaning device; Description of the embodiment

[0051] Fig. 1 shows a vacuum cleaner 10 according to the invention with a vacuum cleaner housing 12, a filter 16, a filter fastening element 20, a filter cleaning device 200, and a suction hose 36. Here, the vacuum cleaner housing 12 comprises an upper housing part 13 and a dust collection container 14 as a lower housing part. In this embodiment of the invention, the suction hose 36 can be reversibly and detachably attached to the vacuum cleaner housing 12.

[0052] In this exemplary embodiment, the suction device 10 is designed as a battery-operated suction device, which is operated by means of at least one battery 82, in particular by means of a handheld power tool battery pack. Thus, the required energy for the suction device 10 is provided by a power supply 81 using the at least one battery 82. The battery 82 is connected to the power supply 81 via a power supply coupling means 84.
