The electrical processing device 1 is designed as a motor-driven chainsaw. The processing system 100 has a battery pack B designed to store electrical energy. The battery pack B is designed as a rechargeable battery pack. The battery pack B is exchangeably received by means of a receiving device 5 of the electrical processing device 1 in order to supply a tool device 4, which is attached to the electrical processing device 1, in this case detachably, with drive power based on stored electrical energy. The tool device 4 is in particular not a component of the electrical processing device 1. The battery pack B is in particular not a component of the electrical processing device 1. The tool device 4 can be included in the processing system 100.The electrical processing device 1 in this case has a tool attachment device 3, to which the tool device 4 is attached, in this case detachably. Unless otherwise stated and / or otherwise exclusive, in particular contextually and / or in view of the drawings, the present description of the exemplary embodiments can apply to all exemplary embodiments.

[0124] The electrical processing device 1 has a mounting plane E and a mounting section 2. The mounting section 2 is designed to contact a substrate U in the mounting plane E. The substrate U is not a component of the electrical processing device 1. The tool attachment device 3 serves for, for example, detachably attaching and / or coupling the tool device 4.

[0125] In this case, the longitudinal extension direction LE runs parallel to the installation plane E of the electrical processing device 1. The installation plane E runs, for example, perpendicular to a direction of gravity G when the electrical processing device 1 - for example in its rest state - is placed on a horizontal surface U.

[0126] The longitudinal extension direction LE can also be parallel to a tool plane W. A movement of the tool device 4 attached to the electrical processing device 1 relative to the electrical processing device 1 resulting from the drive power can, for example, take place within the tool plane W. If the electrical processing device 1 is designed as a power chain saw, as in the present case, and the tool device 4 is designed with a rotating saw chain, the saw chain can, for example, extend rotatingly within the tool plane W and - alternatively or additionally - be guided.

The battery pack B to be received can be inserted into the receiving space 11 in the receiving direction A through the receiving opening 14.

[0130] The receiving space 11 can—as in the present case—have a cross-sectional area running perpendicular to the receiving direction A. The cross-sectional area can—as in the present case—be rectangular. It is understood that other cross-sectional shapes are also conceivable.

[0131] According to Figs. 1 to 4, the first receiving space end 12 of the receiving space 11 faces away from the installation plane E. The second receiving space end 13 of the receiving space 11 faces the installation plane E. A distance between the first receiving space end 12 and the installation plane E can be greater than a distance between the second receiving space end 13 and the installation plane E.

[0132] The receiving device 5 has, for example, an electrical connection device 18. The electrical connection device 18 serves to electrically connect the received battery pack B. In this case, the electrical connection device 18 forms a stop 19 for the received battery pack B in the receiving direction A. Alternatively or additionally, the electrical connection device 18 can be arranged along the receiving direction A - for example, as shown in Figs. 1 to 4, directly - between the receiving space 11 and the installation plane E.

[0133] The electrical processing device 1 has, for example, a through-opening 20. The through-opening 20 is designed to remove foreign matter from the receiving space 11. The through-opening 20 can be covered by a grid element, in particular an integral one, of the electrical processing device 1, which allows foreign matter to pass through. In this case, the through-opening 20 opens the receiving space 11 to the outside in the receiving direction A, in particular allowing foreign matter to pass through. In this case, the through-opening 20 is arranged opposite the receiving opening 14 along the receiving direction A. The through-opening 20 can adjoin the second receiving space end 13 in the receiving direction A.

[0134] The receiving device 5 has, for example, a bottom section 21 which is opposite the receiving opening 14 along the receiving direction A.

[0136] The receiving device 5 has, for example, at least one, in this case exactly one, user-operable locking lever 24. The locking lever 24 is designed to releasably secure the received battery pack B. The locking lever 24 can—as in the present case—be arranged on a side of the receiving device 5 facing the tool attachment device 3.

[0137] The electrical processing device 1 has a user-operable operating device 6. The user-operable operating device 6 is designed for operating the electrical processing device 1, in particular by a user. The receiving device 5 is arranged, for example, between the tool attachment device 3 and the operating device 6.

[0138] Viewed perpendicular to the installation plane E, the operating device 6 and the receiving device 5 are arranged so as to overlap one another at least in regions, see in particular Fig. 2. In the present case, the operating device 6 and the receiving device 5 - viewed perpendicular to the installation plane E - are arranged so as to overlap one another only in regions with respect to the longitudinal direction LE of the electrical processing device 1. According to Figs. 1 to 4, the receiving direction A runs away from the tool attachment device 3 at an oblique, in particular acute, angle a relative to the installation plane E. The oblique angle a between the receiving direction A and the installation plane E is, for example, greater than or equal to 45°, in the present case greater than or equal to 75°. Alternatively or additionally, the oblique angle a is less than 90°, in particular less than or equal to 80°. In the present case, the oblique angle a is approximately 80°.The tool attachment device 3 and the operating device 6 are arranged at a distance from one another along the longitudinal extension direction LE of the electrical processing device 1. The oblique angle α can widen toward the tool attachment device 3. The electrical processing device 1 has an electric drive device 7. The electric drive device 7 is designed to generate drive power for the tool device 4 that can be attached to the electrical processing device 1—and is attached here. The electric drive device 7 comprises, for example, an electric motor.

[0139] The electrical processing device 1 has a tank 8. The tank 8 defines, with its inner side, a tank interior 9 of the electrical processing device 1. The tank interior 9 is designed to store a lubricant. The lubricant can be synonymously referred to as a lubricant. The lubricant can be a lubricating fluid, in particular lubricating oil.

[0140] The position of the total center of mass M of the electrical processing device 1, for example, variably depends on the current fill level of lubricant in the tank interior 9. The present arrangement of the tank 8 allows a particularly small degree of this variability in the position of the total center of mass M to be achieved.

[0141] The receiving device 5 and the drive device 7 are arranged at a distance from one another along a longitudinal direction LE of the electrical processing device 1. At least one interior section 10 of the tank interior 9 is arranged between the drive device 7 and the receiving device 5. In the present case, the interior section 10 is arranged between the drive device 7 and the receiving device 5 with respect to the longitudinal direction LE. Along the longitudinal direction LE, the interior section 10 can be overlapped on the one hand by the receiving device 5 and on the other hand by the drive device 7. For example, the interior section 10 of the tank interior 9 is flanked on the one hand by the receiving device 5 along the longitudinal direction LE. Alternatively or additionally, the interior section 10 is flanked on the other hand by the drive device 7.The tank 18 can be limited by the drive device 7 and - alternatively or additionally - touched.

[0142] For example, the tank interior 9 has a tank interior volume. The interior section 10 has an interior section volume. The interior section volume is, in particular, a portion of the tank interior volume. The ratio of the interior section volume to the tank interior volume is at least 50%, in this case at least 60%.

[0143] Viewed perpendicular to the installation plane E, the tank interior 9 and the receiving device 5 are arranged, for example, to overlap one another at least in sections. In the present case, the interior section 10, viewed along the installation plane E, is arranged to overlap the receiving device 5 at least in sections. For example, the tank interior 9 and the receiving device 5 overlap one another along the longitudinal direction LE, in the present case only in sections.

[0144] In the present case, 2% to 15%, in particular up to 30%, more particularly up to 40%, of the tank interior volume of the tank interior 9 is overlapped by 2% to 15%, in particular up to 30%, of the receiving space 11 of the receiving device 5 viewed perpendicular to the installation plane E, see in particular Fig. 2.

[0145] In the present case, the tank 8 has a wall section 15. The wall section 15 extends along the installation plane E of the electrical processing device 1. Alternatively or additionally, the tank 8 can have another wall section 16, as in the present case. The other wall section 16 extends, for example, along, in particular parallel to, the receiving direction A and, alternatively or additionally, along the receiving device 5. Alternatively or additionally, the tank 8 can have a further wall section 17, as in the present case. The further wall section 17 partially surrounds the drive device 7 around a rotation axis D of the drive device 7.

[0146] The drive device 7 has, for example, a fan wheel 42 that can be rotated about the rotational axis D of the drive device 7. The fan wheel 42 is designed to generate a cooling air flow. The fan wheel 42 has a, in particular virtual, circumferential circle C. As can be seen, for example, from Fig. 4, when viewed along the rotational axis D, a vertical tangent TV running perpendicular to the installation plane E and applied to the circumferential circle C by the receiving device 5, in particular a virtual one, does not intersect the tank 8. Alternatively or additionally, as in the present case, when viewed along the rotational axis D, a horizontal tangent TH running parallel to the installation plane E and applied to the circumferential circle C on the side facing away from the installation plane E, in particular a virtual one, may not intersect the tank 8. The two tangents TV, TH are in particular perpendicular to one another.

[0147] For example, viewed along the rotational axis D of the drive device 7, more than 25%, in particular more than 50%, in particular more than 75%, in the present case more than 80%, of the tank interior volume of the tank interior 9 is present between the rotational axis D and the receiving device 5.

[0148] In this case, the electrical processing device 1 has an air guide housing 43 for guiding the cooling air flow. The tank 8 directly adjoins the air guide housing 43 or—as in the present case—is formed integrally with the air guide housing 43, in particular with at least one component of the air guide housing 43.

In the present case, the handle section 25 is longitudinally extended at a distance from the installation plane E and transversely to the receiving direction A and at an angle to the longitudinal direction LE.

[0150] The operating device 6 is arranged, for example, between the receiving device 5 and the handle section 25. The operating device 6 can be arranged along the longitudinal direction LE and—alternatively or additionally—directly between the receiving device 5 and the handle section 25. In the present case, the operating device 6 is arranged along the longitudinal direction LE directly between the receiving device 5 and the handle section 25.

[0151] The handle section 25 can be arranged along a handle extension direction GE, in the present case from the

[0152] The handle extension direction GE can be elongated, directed away from the tool attachment device 3. The handle extension direction GE can run at an acute handle angle β, for example, from 15° to 45°, relative to the installation plane E, wherein the handle angle β widens away from the tool attachment device 3. The handle extension direction GE can be set at a different angle γ relative to the receiving direction A. The other angle γ can widen towards the installation plane E, as in the present case. The other angle γ can be 30° to 70°, for example, approximately 60°, as in the present case.

[0153] The receiving device 5 is arranged, for example, between the tank 8 and the operating device 6. In the present case, the receiving device 5 is arranged along the longitudinal direction LE, in particular directly, between the tank 8 and the operating device 6.

[0154] The operating device 6 can be arranged at an end region 41 of the handle section 25 facing the receiving device 5. In the present case, the operating device 6 is arranged at the end region 41 of the handle section 25 facing the receiving device 5, pointing away from the installation plane E.

[0155] The operating device 6 has, for example, a display device 26. The display device 26 can have an electronic display 27. Alternatively or additionally, the operating device 6 has an input device 28. The input device 28 can have at least one electrical button 29. The button 29 can form at least one input element 40 of the input device 28; the input device 28 can have at least two electrical buttons 29, for example, exactly two as in the present case.

[0156] A reference plane RE of the handle portion 25, oriented perpendicular to the installation plane E and parallel to the longitudinal direction LE, in particular a central and—alternatively or additionally—virtual, reference plane RE, can extend between various input elements 40 of the operating device 6. The input elements 40 can be—as in the present case—the buttons 29 of the operating device 6.

[0157] The operating device 6 and—alternatively or additionally—the handle section 25 are arranged on an upper side 32 of the electrical processing device 1. In this case, the upper side 32 is opposite the installation plane E. Alternatively or additionally, the upper side 32 can face away from the installation plane E—as in this case.

[0158] The display device 26 can be provided, in particular, on the upper side 32. The display device 26 can be exposed on the upper side 32. The display device 26 can be inclined relative to the installation plane E, pointing away from the receiving device 5. The display device 26 can extend along the handle extension direction GE.

[0159] For example, the electrical processing device 1 has an electronic control device 30. The electronic control device 30 is, for example, connected, in particular electrically, to the drive device 7 and—alternatively or additionally—to the operating device 6. In the present case, the control device 30 is connected, in particular electrically, to both the drive device 7 and the operating device 6.

[0160] For example, the drive device 7 is arranged, in this case along the longitudinal direction LE, between the control device 30 and the receiving device 5. The drive device 7 can also be arranged—as in the present case—between the control device 30 and the tank 8. In particular, the drive device 7 is arranged along the longitudinal direction LE between the control device 30 and the tank 8. The drive device 7 can be arranged directly between the control device 30 and the tank 8. The drive device 7 can be arranged directly between the control device 30 and the receiving device 5.

[0161] Viewed perpendicular to the installation plane E, the operating device 6 and the receiving device 5 are arranged in this case so as to overlap one another at least in some areas. For example, the operating device 6 and the receiving device 5—viewed perpendicular to the installation plane E—are arranged so as to overlap one another at least in some areas along the longitudinal direction LE. The operating device 6 and the receiving device 5 can be arranged so as to overlap one another only in some areas.

[0162] The electrical processing device 1 has, for example, a user-operable actuating device 31. The user-operable actuating device 31 can be designed to specify, in particular continuously or stepwise, the drive power to be provided by the drive device 7.

[0163] The actuating device 31 and the operating device 6 can overlap each other—viewed perpendicular to the installation plane E—at least in regions, in particular along the longitudinal direction LE of the electrical processing device 1. Alternatively or additionally, the actuating device 31 and the operating device 6—viewed perpendicular to the installation plane E—can not overlap each other, in particular along the longitudinal direction LE, as is the case here. To illustrate the overlaps, a first vertical virtual line L1 and a second vertical virtual line L2 are shown in dash-dotted lines in Fig. 4 as an example.

[0164] The receiving device 5 has, for example, a guide side F. The guide side F extends along the receiving direction A and perpendicular to the receiving direction A. The guide side F can be substantially flat, in particular planar. The guide side F can be profiled with respect to the receiving direction A, but in particular can be evenly extended on average.

[0165] 1 to 4, the guide side F and the receiving direction A, in particular together, point away from the tool attachment device 3 at the oblique angle a relative to the installation plane E. In contrast, according to Fig. 5, the receiving direction A runs parallel to the installation plane E, wherein the guide side F extending along the receiving direction A and perpendicular to the receiving direction A runs at the acute angle a relative to the installation plane E. The oblique angle a opens up both according to Figs. 1 to 4 and also according to Fig. 5, in particular exactly, towards the tool attachment device 3.

[0166] The receiving device can - as in the present case - have two guide sides F running perpendicular to the receiving direction A, plane-parallel and / or mirror-symmetrically opposite each other.

[0167] In contrast to Figs. 1 to 4, according to Fig. 5, the first receiving space end 12 and the second receiving space end 13 are arranged opposite one another along the installation plane E and perpendicular to the longitudinal direction, in particular along a width of the electrical processing device 1. Whereas according to Figs. 1 to 4, the battery pack B can be received from above, according to Fig. 5, the battery pack B can be received laterally.

[0168] For example, a refill opening 46 for refilling lubricant, which opens the tank interior 9 outwards, is arranged along the longitudinal direction LE between the receiving device 5 and the rotation axis D of the drive device 7. The refill opening 46 can be releasably closed by means of a tank cap 47 of the electrical processing device 1. The refill opening 46 can be arranged on a tank nozzle 48 of the electrical processing device 1. The refill opening 46 can open the tank interior 9, in particular directly the interior section 10, outwards transversely to the longitudinal direction LE and / or along the installation plane E. The receiving device 5 is arranged, for example, along the longitudinal direction LE and—alternatively or as in the present case additionally—transversely to the receiving direction A between the handle section 25 and the drive device 7.

[0169] The drive device 7 can - viewed perpendicular to the installation plane E - be partially overlapped by the receiving device 5, in particular with respect to the longitudinal extension direction LE.

[0170] For example, an imaginary first vertical plane of the electrical processing device runs perpendicular to the installation plane E. This first vertical plane contains the axis of rotation D of the drive device 7. An imaginary second vertical plane of the electrical processing device runs parallel to the first vertical plane and touches an overlap end of the overlap between the receiving device 5 and the tank interior 9 facing the drive device 7. The second vertical plane can correspond to the vertical line L1 in the side view of Fig. 4 or contain the vertical line L1. An imaginary third vertical plane of the electrical processing device 1 runs between the first vertical plane and the second vertical plane. The third vertical plane runs parallel to the first vertical plane and to the second vertical plane.The third vertical plane runs tangentially to the drive device 7, in particular tangentially to an outer circumference of the drive device 7, more particularly tangentially to a laminated core circumferential circle of a laminated core, in particular a stator laminated core, of the electric motor of the drive device 7. The laminated core circumferential circle can be concentric, possibly even identical, to the circumferential circle C of the rotatably drivable fan wheel 42 of the electrical processing device 1. 75% to 90% of the tank interior volume adjoins the first vertical plane, pointing towards the receiving device 5, in particular opposite to the longitudinal extension direction LE.

[0172] Recording device 5 pointing to the second vertical plane 30% to 10% of the

[0173] Alternatively or additionally, 55% to 65% of the tank interior volume are connected to the receiving device 5, pointing to the third vertical plane.

[0174] Tank interior volume directly.

[0175] In a side view, in particular when viewed along the rotation axis D, more particularly see Fig. 3 and / or 4 and / or 5, a center of the refill opening 46 can be arranged behind the rotation axis D and in front of the receiving device 5, opposite to the longitudinal direction LE. For example, the center of the refill opening 46—when viewed along the rotation axis D—can be arranged between the receiving device 5 and the rotation axis D with respect to the longitudinal direction LE. In addition to or as an alternative to the above detailed description of some embodiments, the same and / or further embodiments can be described in detail, at least in part, using other words, as follows below (until the end of the description):

[0176] A processing system 100 comprises a hand-held, battery-operated electrical processing device 1, in particular wherein in some of the embodiments shown, only selected or all aspects of the invention are implemented. The electrical processing device 1 is embodied as a power chainsaw. The processing system 100 comprises a battery pack B designed to store electrical energy. The battery pack B is embodied as a rechargeable battery pack. The battery pack B is exchangeably received by means of a receiving device 5 of the electrical processing device 1 in order to supply a tool device 4, which is attached to the electrical processing device 1, in this case detachably, with drive power based on stored electrical energy. The tool device 4 is, in particular, not a component of the electrical processing device 1. The battery pack B is, in particular, not a component of the electrical processing device 1.The tool device 4 can be included in the processing system 100. The electrical processing device 1 in this case has a tool attachment device 3, to which the tool device 4 is attached, in this case detachably. Unless otherwise stated and / or otherwise exclusive, in particular contextually and / or in view of the drawings, the present description of the exemplary embodiments can apply to all exemplary embodiments.

[0177] The electrical processing device 1 has an electrical drive device 7 for generating the drive power for the tool device 4 attachable to the electrical processing device 1. The drive device 4 has a rotational axis D, around which a drive shaft AW of the drive device 7 can be driven in rotation. The electrical processing device 1 also has a rotationally drivable fan wheel 42 for generating a cooling air flow. The rotationally drivable fan wheel 42 is seated on the drive shaft AW of the drive device 7 in such a way that it can be driven in rotation about the rotational axis D together with the drive shaft AW. Accordingly, the fan wheel 42 can be understood here as being provided by the drive device 7.

[0178] The electrical processing device 1 has an air guide housing 43, which in this case defines a flow path 50 for the cooling air flow generated by the fan impeller 22. The electrical processing device 1 has, for example, a tank 8, which defines a tank interior 9 of the electrical processing device 1 on the inside. The tank interior 9 serves in this case to store a lubricant. The lubricant can be a lubricating fluid, in particular a lubricating oil.

[0179] In this case, the tank 8 is formed integrally with the air duct housing 43. The air duct housing 43 and the tank 8 form, for example, a monolithic unit. The monolithic unit can be made of a plastic material, in particular a technical plastic material, in this case a thermoplastic. The monolithic unit can have two elements that are inseparably connected to one another, in particular welded.

[0180] The electrical processing device 1 has, for example, an inlet opening 51 designed to admit air for the cooling air flow. The inlet opening 51 can be provided by the air guide housing 43. The air guide housing 43 can therefore have the inlet opening 51. The flow path 50 adjoins, for example, the inlet opening 51, in particular directly. The flow path 50 has, for example, a first path section 60 which, starting from the inlet opening 51, extends essentially parallel to the axis of rotation D. In addition, the flow path 50 has, for example, a second path section 61 which adjoins the first path section 60 at an angle opposite the inlet opening 51. For example, the second path section 61 adjoins, pointing towards the installation plane E of the electrical processing device 1.

[0181] The electrical processing device 1 has, for example, a mounting section 2 that defines a mounting plane E. The mounting section 2 is designed to contact a substrate U in the mounting plane E. The substrate U is not a component of the electrical processing device 1.

[0182] The air guide housing 43 has, for example, an electronics receptacle opening 62. The electronics receptacle opening 62 is hermetically sealed, for example, by an electronic control device 30 of the electrical processing device 1. The electronic control device 30 can be designed to control the drive device 7. The electronics receptacle opening 62 is hermetically sealed, for example, by the control device 30 such that the flow path 50 for cooling the control device 30 by means of the cooling air flow in the region of the electronics receptacle opening 62 runs in sections along the control device 30. The electronics receptacle opening 62 can be arranged in and / or on the second path section 61 of the flow path 50.For example, a sealing device 63 is provided which lines the electronics receiving opening 62 and is designed and / or compressible for airtight engagement with a complementary edge portion 64 of the control device 30.

[0183] The control device 30 can have a heat sink 65 and / or electronic components 66, which, when the control device 30 is mounted on the air guide housing 43, protrude into the second path section 61, where it is surrounded by the cooling air flow. In particular, all electronic connections, especially between the electronic components 66, of the control device 30 are electrically insulated and / or hermetically separated from the flow path 50.

[0184] For example, the flow path 50 has a third path section 67, which extends at a distance from the inlet opening 51 and away from the electronic control device 30 of the electrical processing device 1, essentially orthogonal to the rotation axis D. The drive device 7 has, for example, an electric motor region 52. For example, the third path section 67 runs along the electric motor region 52 for cooling the electric motor region 52 by means of the cooling air flow.

[0185] For example, the electrical processing device 1 has a fan device 70, which has the fan wheel 42. The air guide housing 43 can have a fan spiral contour 68. The fan spiral contour 68 defines, for example, a fourth path section 71 of the flow path 50. The fourth path section 71 can extend, in particular in a winding manner, from the electric motor region 52 of the drive device 7 around the rotation axis D. The fourth path section 71 can end at an air outlet opening 72 of the electrical processing device 1, in particular perpendicular to the installation plane E and / or open to the outside.

[0186] For example, the air guide housing 43 has a recess 73, in particular a substantially central and / or continuous recess, which is designed to accommodate the drive device 7.

[0187] For example, a complementary spiral cover part 69 of the electrical processing device 1 can be mounted, in particular detachably, on the fan spiral contour 68.

[0188] The tank 8, for example, has a refill opening 46 for refilling lubricant.

[0189] Refill opening 46 can be releasably closed by means of a tank cap 47. The refill opening 46 opens the tank interior 9, for example, along the rotation axis D, in particular toward a lateral outer side of the electrical processing device 1.

[0190] 6 and 7, for example, an imaginary horizontal line HL running parallel to the installation plane E and an imaginary vertical line VL running orthogonal to the installation plane E intersect the rotation axis D. The vertical line VL and the horizontal line HL span an imaginary quadrant QVO which widens, in particular forwards and upwards, essentially towards the tool attachment device 3 and away from the installation plane E. The inlet opening 51 is, for example, arranged entirely within this quadrant QVO. For example, when viewed along the rotation axis D, the first path section 60 of the flow path 50 is arranged at least partially, in particular entirely, within this quadrant QVO.

[0191] The longitudinal direction LE can run from "back" to "front," i.e., "front" can mean "in the longitudinal direction." "Back" can correspondingly mean "opposite the longitudinal direction."

[0192] When the power tool 1 is mounted on a horizontal surface U using the mounting section 2, the direction of gravity G can run from "top" to "bottom." "Down" can mean "in the direction of gravity G." "Up" can mean "opposite the direction of gravity G."

[0193] Viewed along the rotation axis D, the refill opening 46 of the tank 8 can be arranged in a counter quadrant QHU, which is diametrically opposite the quadrant QVO. Alternatively or additionally—viewed along the rotation axis D—a large portion of the tank interior volume of the tank interior 9 can be arranged in the counter quadrant QHU. For example, at least 50%, in particular at least 75%, of the tank interior volume, viewed along the rotation axis D, is arranged in the counter quadrant QHU.

[0194] As already mentioned, the flow path 50 runs, for example, in sections along the control device 30 in order to cool the control device 30 by means of the cooling air flow guided through the flow path 50. As also already indicated, the flow path 50 runs, for example, in sections along the electric motor region 52 in order to cool the electric motor region 52 by means of the cooling air flow guided through the flow path 50.

[0195] For example, the control device 30 is arranged between the inlet opening 51 and the electric motor region 52 with respect to the course of the flow path 50, in particular along the course of the flow path 50. Alternatively or additionally, the electric motor region 52 can be arranged between the electronic control device 30 and the fan wheel 40 with respect to the course of the flow path 50.

[0196] The electronic control device 30 of the electrical processing device 1 is, for example, - viewed along the rotation axis D - arranged at least or only partially in the quadrant QVO.

[0197] The electrical processing device 1 has, for example, a filter chamber 54, which adjoins the inlet opening 51, facing away from the flow path 50. The filter chamber 54, see in particular Fig. 7, is covered in an air-permeable manner by an air filter element 55 of the electrical processing device 1, opposite the inlet opening 51. For example, the air filter element 55 covers the filter chamber 54 in such a way that ambient air 56 can pass through the air filter element 55 into the filter chamber 54 and from there through the inlet opening 51 to the flow path 50 as filtered cooling air.

[0198] The air filter element 55 is, for example, substantially flat and—alternatively or additionally—planar. Alternatively or additionally, the air filter element 55 can be arranged laterally of the tool attachment device 3, for example, on a lateral outer surface 57 of the electrical processing device 1.

[0199] For example, the inlet opening 51 has an inlet opening cross-sectional area oriented perpendicular to the rotation axis D. The air filter element 55, which is arranged at a distance from the inlet opening 51 and through which air to be filtered can flow such that the air filtered by the air filter element 55 can be fed to the flow path 50 through the inlet opening 51, has an air filter element cross-sectional area oriented perpendicular to the rotation axis D. The surface area of ​​the air filter element cross-sectional area corresponds, for example, to a multiple, in particular at least 4 times, in particular 6 times, in particular 8 times, in this case approximately 10 times, of the surface area of ​​the inlet opening cross-sectional area. The electrical processing device 1 has, for example, a handle tube 58.For example, the handle tube 58 extends longitudinally in sections essentially parallel to the vertical line VL through the quadrant QVO, as viewed along the rotation axis D. The handle tube 58 can at least partially overlap the inlet opening 51 within the quadrant QVO, as viewed along the rotation axis D.

[0200] The electrical processing device 1 has, for example, a hand guard 59. The hand guard 59 protrudes, for example—viewed along the rotation axis D—within the quadrant QVO, pointing away from the installation plane E, in particular essentially in extension of the inlet opening 51.

[0201] The air guide housing 43 has, for example, a housing section 74 that is aligned with the electronics receiving opening 62. The electrical processing device 1 has, for example, a flexible tolerance compensation device 75 that is arranged on the housing section 74 that is aligned with the electronics receiving opening 62. The tolerance compensation device 75 can be pressed and / or glued against the housing section 74.

[0202] For example, at least one heat sink projection 76 of the control device 30 extends through the flow path 50 such that a free end of the at least one heat sink projection 76 is in contact with the tolerance compensation device 75. Alternatively or additionally, at least one electronic component 66 of the control device 30 can extend through the flow path 50 such that a free end of the at least one electronic component 66 is in contact with the tolerance compensation device 75.

[0203] As already mentioned, the control device 30 has, for example, a heat sink 65. The heat sink 65 has, for example, a plurality of heat sink projections 76 arranged at a distance from one another. The heat sink projections 76 can be arranged at a distance from one another such that cooling air can flow through the spaces between the heat sink projections 76. The heat sink projections 76 are, for example, rod-shaped. Alternatively or additionally, the heat sink projections 76 can be pin-shaped. Further additionally or alternatively, the heat sink projections 76 can be peg-shaped. It is conceivable to alternatively or additionally design the heat sink projections 76 rib-like. As also already mentioned, the control device 30 has, for example, a circumferential edge section 64 which is designed for airtight contact with an opening edge 77 of the electronics receptacle opening 62.The opening edge 77 and - alternatively or additionally - the edge section 64 can have a flexible sealing device 63 lining the electronics receiving opening 62.

[0204] For example, some heat sink protrusions 76 and / or some electronic components 66 are arranged in groups to form a first grouping 78 of the electrical processing device 1. Other heat sink protrusions 76 and / or other electronic components 66 are arranged in groups, for example, to form a second grouping 79 of the electrical processing device 1. The heat sink protrusions 76 and / or the electronic components 66 of the first grouping 78—measured from the edge section 64—are longer than the other heat sink protrusions 76 and / or the other electronic components 66 of the second grouping 79.

[0205] The housing section 74 and / or the tolerance compensation device 75 can have a profile tailored to the different lengths of the groupings 78, 79. For example, the housing section 74 and / or the tolerance compensation device 75 can have a profile tailored to the groupings 78, 79 in a stepped manner. Alternatively or additionally, the tolerance compensation device 75 can have a profile tailored to the different lengths of the groupings 78, 79 in terms of material thickness.

[0206] For example, the first grouping 78 comprises only heat sink protrusions 76, in particular no electronic components 66. The second grouping 79 may comprise only electronic components 66, in particular no heat sink protrusions 76.

[0207] The electronic components 66 may be in the form of electrical capacitors 80.

[0208] For example, the first grouping 78 and the second grouping 79 are arranged such that they are supplied with cooling air from the cooling air flow guided through the flow path 50 in a parallel arrangement. In particular, the first grouping 78 and the second grouping 79 cannot be supplied with cooling air in series within the flow path.

[0209] For example, a material 81 of the tolerance compensation device 75 comprises a foam 82, in particular a closed-cell foam 82. The material 81 of the tolerance compensation device 75 can consist of the, in particular closed-cell, foam 82.

[0210] The tolerance compensation device 75 can have a plurality of pieced compensation elements 83. Alternatively, it is conceivable that the tolerance compensation device 75 has a single compensation element 83.

[0211] The flexible sealing device 63 lining the electronics receiving opening 62 and at least one, for example each, compensating element 83 of the tolerance compensation device 75 can be made of a same material 81.

[0212] To produce the sealing device 63 and at least one, in particular each, compensating element 83, a manufacturing method can be carried out which comprises the following steps a), b), and c). According to step a) of the method, a flat semi-finished product made of flexible raw material is provided. The flat semi-finished product can be, for example, a foam rubber mat. According to step b) of the method, the sealing device 63 is separated from the semi-finished product. The separation can be carried out, for example, by punching. In this process, the sealing device 63 is separated in such a way that a core region 58 made of raw material, previously surrounded by the sealing device 63, is obtained. According to step c) of the method, this core region 85 resulting from the separation of the sealing device 63 from the semi-finished product is used for at least one or as a compensating element 83.
