In order to prevent the suction material from reaching the housing outer surface of the enclosing element during the regeneration operation, it is proposed that the regeneration channel has a channel recess on the inner side which corresponds to the shape of the enclosing element, which forms a recess in the inner wall of the regeneration channel, the enclosing element being movable into the channel recess during the regeneration operation, so that in the state in which the suction cleaning device and the base station are separated from one another, the outwardly directed outer side of the enclosing element is embedded in the channel recess and the suction material flowing along the regeneration channel cannot flow either into the channel recess or between the enclosing element and the inner wall of the channel recess.

Description

Technical Field

[0001] This invention relates to a system comprising a suction-type cleaning device and a base station for the suction-type cleaning device, wherein the suction-type cleaning device has a nozzle, a suction chamber, and a fan, the nozzle, the suction chamber, and the fan being fluidly connected to each other during suction operation, the fluid connection allowing suction material to be drawn from the surface to be cleaned through the nozzle into the suction chamber by means of the fan, and wherein the suction chamber for regeneration operation is connectable to the base station chamber of the base station via a regeneration channel of the suction-type cleaning device and / or a regeneration channel of the base station, so as to introduce suction material from the suction chamber of the suction-type cleaning device into the base station chamber of the base station, and wherein the suction-type cleaning device and / or the base station has a sealing element for disconnecting the fluid connection between the suction chamber and the base station chamber. Background Technology

[0002] Base stations for suction cleaning equipment and suction cleaning equipment are well known in the prior art.

[0003] Such suction-type cleaning equipment can be, for example, a vacuum cleaner. Furthermore, the term "suction-type cleaning equipment" can also include other equipment capable of performing at least one suction cleaning action, such as a combination vacuum cleaner, a polishing and grinding device with suction or other functions. The base station is used to perform service activities on the suction-type cleaning equipment, that is, to perform at least the transfer of suction material from the suction chamber of the suction-type cleaning equipment to the base station chamber of the base station. To empty the suction chamber of the suction-type cleaning equipment during so-called regeneration operation, a fan from the base station, a built-in fan of the suction-type cleaning equipment whose suction airflow is redirected, or an external fan can be used. In addition, the base station can, in principle, also use the suction-type cleaning equipment to perform other service activities, such as charging batteries, cleaning mechanical components, etc.

[0004] To regenerate the suction-type cleaning equipment using a base station, the suction-type cleaning equipment is fluidly connected to the base station via a regeneration channel, thus establishing a flow connection between the suction chamber of the suction-type cleaning equipment and the base station chamber of the base station. The regeneration channel can be either attached to the suction-type cleaning equipment or attached to the base station. Alternatively, both the suction-type cleaning equipment and the base station can have regeneration channels that are interconnected for regeneration operation. This is possible, for example, if neither the suction chamber nor the base station chamber is directly adjacent to the outer wall of the suction-type cleaning equipment or the base station housing and, correspondingly, is directly connected to the external environment through chamber openings. The base station may, for example, have a base station chamber whose opening does not coincide with the plane of the base station housing outer wall but is connected to the housing opening via an internal regeneration channel. The regeneration channel serves at least as a flow channel through which the suction material flows directly during regeneration operation.

[0005] A known drawback of existing systems is that the enclosing element of a suction-type cleaning device or base station operates to access the regeneration channel, where air filled with the suction material circulates around it. For example, in existing suction-type cleaning devices, the enclosing element is a flexible plastic flip-top that moves into the device due to suction. If this enclosing element is a localized area forming the outer wall of the housing, dust and dirt remain on the outside of the enclosing element after the regeneration process. This is unhygienic and may pose health risks, especially for allergy sufferers.

[0006] Technical content

[0007] Based on the above-mentioned prior art, the technical problem to be solved by the present invention is to provide a system consisting of a suction cleaning device and a base station, wherein the suction chamber of the suction cleaning device can be hygienically regenerated, and in particular, no suction material is left on the outside of the sealing element of the suction cleaning device.

[0008] To address the aforementioned technical problems, the present invention proposes that the regeneration channel has a channel recess on its inner side corresponding to the shape of the sealing element. The channel recess forms a depression in the inner wall of the regeneration channel, and the sealing element can move into the channel recess during regeneration operation, such that when the suction cleaning device and the base station are separated, the outwardly pointing outer side of the sealing element is embedded in the channel recess, and the suction material flowing along the regeneration channel cannot flow into the channel recess or between the sealing element and the inner wall of the channel recess.

[0009] According to the invention, the sealing element of the suction cleaning device and / or the sealing element of the base station are moved into the regeneration channel such that, when the suction cleaning device and the base station are not interconnected, the outer side of the sealing element is fitted into a channel recess provided for it, so that the outer side is not surrounded by suction material and air. This can be achieved by designing the channel recess to correspond to the shape of the sealing element and the outer side abutting airtightly against at least one local area of ​​the channel recess. The outer side of the sealing element is protected at least by the channel recess such that local areas of the sealing element that may be touched by the user, for example, during the suction operation of the suction cleaning device, are not covered by suction material. When dust and dirt are sucked from the suction chamber, the suction material does not adhere to the housing of the suction cleaning device and / or the base station, despite the flow connection with the base station. Even during the establishment of the flow connection between the suction chamber and the base station chamber, it is preferable that the flow path is always sealed and that allergen-inducing particles do not leave the suction cleaning device or the base station uncontrollably. This is achieved in such a way that the suction cleaning device and the base station are always in a controlled and defined operating state, and there is no undefined "intermediate state" that allows flow around the outside of the sealing element, even if it is only for a very short time. In the state where the suction cleaning device is separated from the base station, the outward flow path of the suction cleaning device and the base station is closed by corresponding sealing elements. Here, the suction material does not escape from the suction cleaning device or the base station. In the second state where the suction cleaning device is connected to the base station, the flow path of the suction material is designed so that the outside of the sealing element of the suction cleaning device and the base station does not come into contact with the suction material. Furthermore, the suction cleaning device and the base station are airtightly connected to each other through a regeneration channel, so that the suction material does not reach the surrounding environment of the system. For this purpose, the suction cleaning device and the base station are correspondingly designed so that their housing openings can be aligned with each other and airtightly connected. There are in particular no gaps between the devices through which the suction material can escape. Sealing elements are preferably provided in the area of ​​the housing openings. The housing opening preferably has a corresponding opening cross-section, thereby reducing the tendency to clog and ensuring a consistently high flow velocity at the relevant interface. The flow connection between the suction cleaning device and the base station can be achieved by the simultaneous movement of the sealing element. Alternatively, the sealing elements of the suction cleaning device and the base station can move continuously in time. The sealing element, which has previously closed the flow path, then moves at least partially into the channel recess of the regeneration channel, thereby protecting the outside of the sealing element from the accumulation of suction material. For this purpose, the sealing element can move towards the suction cleaning device or towards the base station. It is feasible for the sealing element of the suction cleaning device to move either into its own channel recess or into the channel recess of the base station.The same applies to the enclosure element of the base station, which can be moved into the channel recess of the base station itself, or alternatively into the channel recess of a suction cleaning device.

[0010] Specifically, the regeneration channel can be specified as being part of the suction-type cleaning device or the base station. The sealing element is preferably located in or on the end region of the regeneration channel, which extends outward onto the housing surface of the suction-type cleaning device or the base station. However, the suction chamber of the suction-type cleaning device or the base station chamber of the base station need not be directly located behind the sealing element. The corresponding chamber can also be connected via a section of the regeneration channel to a flow opening of the suction-type cleaning device or the base station that can be sealed by the sealing element.

[0011] Furthermore, it is suggested that the sealing element of the suction cleaning device and / or the sealing element of the base station be pivotable about a pivot axis from a closed position to an open position. It is feasible here that the sealing element also consists of two sealing element parts that are pivotable relative to each other, particularly in a manner similar to a barn door with two corresponding sealing wings, each of which can be fitted into its own channel recess.

[0012] It is particularly recommended that the pivot axes of the enclosing elements of the suction cleaning device and the base station be merged when the suction cleaning device and the base station are connected, so that the two enclosing elements can pivot about a common pivot center. According to this design, the two enclosing elements pivot coaxially, particularly in the same direction; that is, either both enclosing elements pivot towards the suction cleaning device, or both enclosing elements pivot towards the base station. Preferably, the two outer sides of the enclosing elements are abutted against each other and perform pivoting movements about the common pivot center. Thus, the two enclosing elements move synchronously and in the same manner and method. The corresponding movement of the two enclosing elements of the suction cleaning device and the base station occurs about the same pivot center.

[0013] Relatedly, it is preferably suggested that the suction cleaning device has a groove in the region of the bearing for the pivot axis of the closure element, and a partial region of the bearing of the base station having the pivot axis of the base station's closure element is embedded in the groove, such that the extension line of the pivot axis of the suction cleaning device coincides spatially with the pivot axis of the base station, and vice versa. This also means that, in the same manner and method, the base station can alternatively have a groove in the region of the bearing for the pivot axis of the closure element, and a partial region of the bearing of the suction cleaning device having the pivot axis of the suction cleaning device's closure element is embedded in the groove, such that these pivot axes coincide spatially at least along their extension lines. In general, to achieve overlap of the extending directions of the pivot axes for coaxial movement of the two closure elements, the suction cleaning device or the base station has a gap in the region of the bearing, into which the bearing or pivot axis of the other device, i.e., the base station or the suction cleaning device, can be inserted. This achieves alignment of the pivot axes of the suction cleaning device and the base station.

[0014] It is particularly preferred that the outer surfaces of the sealing elements of the suction cleaning device and the base station, when separated from each other, are shaped to abut each other in the connected state, preventing the suction material from flowing between the two sealing elements. Therefore, according to this design, one sealing element abuts the outer surface of the other sealing element. Subsequently, the two sealing elements can preferably be moved coaxially to the channel recess of the suction cleaning device or base station until one of the sealing elements is at least partially engaged in the channel recess and thus advantageously removed from the flow path of the suction material. Particularly advantageously, the edge of the sealing element not covered by the corresponding other sealing element is covered by the limiting material of the channel recess, so that the suction material cannot enter this area and separate there. Furthermore, if the housing opening of the suction cleaning device or base station is subsequently closed again, the suction material separated on the outer surface of the sealing element will be smeared or displaced.

[0015] Particularly preferably, at least one of the closure elements rests against the inner wall of the regeneration channel within the recess of the channel. This can be implemented across the entire surface, such that the outer side of the closure element rests against the inner wall of the channel or another closure element across its entire surface dimension, or alternatively, only against an edge region, preferably with a sealing element or the like, such that the remaining surface area of ​​the outer side of the closure element is hermetically shielded, preventing the suction portion from reaching the remaining local area of ​​the outer surface.

[0016] In this sense, it is preferred that the outer side of the sealing element, which typically points outward when the suction cleaning device and the base station are separated, has a sealing element, and / or that the channel recess has a sealing element. According to this design, the mutually abutting outer sides of the two sealing elements can be sealed to each other by means of the sealing elements, and / or at least one sealing element seals relative to the inner wall of the regeneration channel, particularly relative to the channel recess. The mutually abutting surfaces can be sealed along the surface edges by means of a sealing profile. Here, the corresponding surfaces can abut each other without tolerance, i.e., without gaps. However, it is preferred that the sealing element is arranged in the middle, where, for example, a flexible sealing element acts on a plastic surface. Furthermore, so-called labyrinthine sealing devices integrated into or arranged on the surface can be used to seal the opposing surfaces. Here, the corresponding components of the sealing device can be formed, in particular, of plastic or elastomer. Additionally, additional magnetic elements can be embedded in the sealing elements; these additional magnetic elements generate an attraction between the mutually sealed surfaces and thus support the sealing action between the surfaces.

[0017] Furthermore, the closure elements of the suction cleaning device and the base station can have corresponding transmission elements, friction engagement elements, shape engagement elements, and / or magnetic elements to fix the variable positions of the closure elements relative to each other for coupled pivoting movements. Additionally or alternatively, the aforementioned magnetic elements can also be used to fix the variable positions of the closure elements to each other for coupled pivoting movements. The transmission elements, friction engagement elements, shape engagement elements, and / or magnetic elements are designed and positioned such that one closure element is coupled to a corresponding closure element in a manner that follows the directional movement of the other closure element. This coupling can be achieved here by means of locking elements, hooks, screw elements, magnetic elements, or the like. Importantly, the design of the first closure element is suitable for driving the corresponding closure element during movement. The particularly temporal and spatially synchronized movement of the closure elements can also be achieved here by mutually coupled transmission elements that induce coordinated movement of the closure elements.

[0018] Furthermore, it is recommended that at least one enclosure element is equipped with a drive mechanism for moving the enclosure element. The suction cleaning device and / or base station may in particular have a switch configured to identify the connection between the suction cleaning device and the base station and trigger the operation of the drive mechanism. The enclosure element may, in principle, be equipped with a manual drive mechanism, such as a mechanical operating device, like a pivotable lever, rotating element, or the like. Alternatively, it may be specified that the enclosure element is equipped with an actuator that moves the enclosure element automatically, particularly electrically, magnetically, pneumatically, or hydraulically. Each enclosure element may be equipped with a separate drive mechanism, which may be individually controlled, but synchronized by means of a common interconnection and / or a common control mechanism. According to another variation, for example, only one enclosure element, preferably the enclosure element of the base station, may be directly equipped with a drive mechanism. This drive mechanism acts indirectly on another enclosure element, for example, on the enclosure element of the suction cleaning device. In this case, the drive mechanism of the base station should have greater power than that of the drive mechanism of the suction cleaning device. Furthermore, although less preferred, it may be specified that a spring element is used as the drive mechanism. The spring element can be placed in a preloaded state and released to operate the closing element. For example, the spring element or associated closing element is secured in a tensioned position by a pawl or the like, thereby maintaining the preload. When its restoring force is released, the spring element performs the same driving task to move the closing element, which can otherwise be alternatively performed by a motor or the like as described above. To drive the closing element in both the opening and closing directions, separate spring elements are required, which must be re-preloaded after operation.

[0019] The drive mechanism for the sealing element is preferably triggered by the operation of a switch. The switch operation can be performed directly by the user or indirectly, for example, when the suction cleaning device is connected to the base station. In the latter case, the switch can be, for example, a contact switch arranged at the contact point between the suction cleaning device and the base station and forcibly operated when the suction cleaning device is connected to the base station. Thus, the switch is operated during the connection process between the suction cleaning device and the base station without requiring a separate operation of the switch itself. However, a preferred method to prevent accidental operation is, for example, to provide a correspondingly shaped protrusion on the base station or suction cleaning device, which is embedded in a corresponding groove on the surface of the suction cleaning device or base station. The switch can then be placed in the groove to prevent accidental operation. The operation of the drive mechanism and the movement of the sealing element preferably only occur when the suction cleaning device is positioned at a defined end on the base station. A small time delay can be specified if necessary to neatly separate the open and closed states of the sealing element. The sealing element preferably has a closed position as a priority position. This preferred position can be secured, in particular by, for example, a pre-tensioned spring element, thus eliminating the need for active control of the corresponding movement of the sealing element to the closed position. Based on this, the sealing element is then reopened by, for example, by a portion of the gravity of the suction cleaning device acting on the contact switch when the suction cleaning device is connected to the base station.

[0027] Figure 6 Showing according to Figure 5 Another view of a local area. Detailed Implementation

[0028] Figure 1 and 1a An exemplary system according to the invention, comprising a suction cleaning device 1 and a base station 2, is shown. The suction cleaning device 1 is, for example, a common household handheld vacuum cleaner, having a base 23, a nozzle 3 for connecting removable accessories to the base, a preferably variable-length handle 24, and a handle 25, on which a switch 18 is provided, allowing the user to, for example, turn the suction cleaning device 1 on and off and select the power level of the fan 5 of the suction cleaning device 1 or similar functions. The suction cleaning device 1 typically has a suction chamber 4 and the aforementioned fan 5 for generating negative pressure, through which suction material such as dust and dirt can be drawn into the suction chamber 4. The suction cleaning device 1 is also designed herein as, for example, a cyclone vacuum cleaner with a separation device 21. The nozzle 3 and the suction chamber 4 are interconnected by a suction channel 22, allowing suction material to reach the suction chamber 4 from the surface to be cleaned. The suction chamber 4 has an exhaust port attached to the housing surface of the suction cleaning device 1, which is closed by a sealing element 8. The sealing element 8 is designed, for example, as a pivotable flip cover.

[0029] Base station 2 is used to perform service activities on the suction-type cleaning device 1, specifically emptying the suction chamber 4 of the suction-type cleaning device 1. However, base station 2 can also perform other tasks, such as charging the battery of the suction-type cleaning device 1 and storing various additional equipment for the suction-type cleaning device 1. Figure 1 In this configuration, a suction-type cleaning device 1 is connected to a base station 2, specifically, it is mounted on the base station 2 in a localized area corresponding to the shape defined for this purpose. A switch 20, for example a contact switch, is provided between the suction-type cleaning device 1 and the base station 2. This contact switch detects the correct positioning of the suction-type cleaning device 1 on the base station 2. The switch 20 may be part of the suction-type cleaning device 1, or, if present, part of the base station 2. The base station 2 also has a base station chamber 7 for receiving the suction from the suction chamber 4 of the suction-type cleaning device 1. The base station 2 also has a regeneration channel 6 that extends from the base station chamber 7 to the housing surface of the base station 2. The regeneration channel 6 is closed at its end on the housing surface by a sealing element 9, preventing the suction from being discharged from the base station chamber 7. The base station 2 may also have a base station fan, not shown here.

[0030] In principle, in two different embodiments, the suction chamber 4 can be designed inside the housing of the suction cleaning device 1, or the base station chamber 7 can be designed inside the housing of the base station 2. On the one hand, if the wall of the suction chamber 4 is directly adjacent to or spatially overlaps with the wall of the housing of the suction cleaning device 1, the regeneration channel 6, as shown here for example inside the suction cleaning device 1, can be completely omitted. Then, a regeneration opening for the suction chamber 4 can be provided, which is also an opening of the housing of the suction cleaning device 1. The base station 2 can also be designed in principle. Alternatively, it is also feasible for the chambers 4 and 7 to be spaced apart from the suction cleaning device 1 or the base station 2, spaced apart from the corresponding housing, and connected to the housing opening via the regeneration channel 6. Here, it is shown according to the following Figures 2 to 4 In one implementation, a regeneration channel 6 is formed inside the base station 2, and the suction chamber 4 of the suction cleaning device 1 is directly adjacent to the outer wall of the housing of the suction cleaning device 1, so that the sealing element 8 of the suction chamber 4 is also the sealing element 8 of the housing.

[0031] Figure 2 This diagram shows a portion of the suction-type cleaning device 1 and a portion of the base station 2, which are coupled together for the regeneration process. (Press...) Figure 2 and 3 The sealing elements 8 and 9 of the suction cleaning device 1 and the base station 2 are in the closed state. The shown portion of the suction cleaning device 1 has a separation device 21 for separating the suction material from the airflow in the suction nozzle 3. The separation device 21 is equipped with a suction chamber 4 and a fan 5. During suction cleaning operation of the suction cleaning device 1, the suction material enters the suction channel 22 from the nozzle 3 and from there enters the separation device 21, where it is separated from the circulating airflow into the suction chamber 4. The pre-purified air may still contain fine dust, which is further guided to a fine dust filter (not shown) and then to the fan 5. To allow removal of the suction material collected in the suction chamber 4, as part of the regeneration process, the suction cleaning device 1 has a sealing element 8 on the housing surface, which allows access to the suction chamber 4 from the outside and proximity to the suction material located therein.

[0032] In order to regenerate the suction chamber 4, the suction cleaning device 1 and the base station 2, as follows: Figure 3 The components are interconnected as shown. In this state, the suction chamber 4 of the suction cleaning device 1 remains sealed by means of the sealing element 8. Furthermore, the regeneration channel 6 of the base station 2 remains sealed by the corresponding sealing element 9. The two outer surfaces of the sealing elements 8 and 9 are in contact with each other. The outer surface of the sealing element 8 of the suction cleaning device 1 has a sealing element 19 at least at its edge. From the sealing elements 8 and 9... Figure 3 Starting from the positions shown, they can move to, for example, Figure 4In the open position shown.

[0033] Figure 5 and 6 Finally, the corresponding areas of the suction cleaning device 1 and the base station 2 are shown, in which pivot axes 13 and 14 and associated bearings 15 and 16 for the enclosure elements 8 and 9 are designed or arranged to achieve coaxial pivoting of the two enclosure elements 8 and 9. This will be discussed in more detail below.

[0034] The invention functions such that the suction cleaning device 1 and the base station 2 are initially completely separated from each other in terms of their flow paths. The closure elements 8 and 9 on both sides close the regeneration flow path from the suction cleaning device 1 to the base station 2. In this state, the suction cleaning device 1 is, for example, directly connected to the base station 2 so that regeneration of the suction chamber 4 can subsequently be performed on the base station 2. By connecting the suction cleaning device 1 to the base station 2, operation... Figure 1a The switch 20 shown is preferably designed as a contact switch on the base station 2. Switch 20 triggers the operation of a drive mechanism (not shown), such as a motor, for automatically moving the sealing elements 8, 9. By being designed as a contact switch, switch 20 is suitable for simultaneously detecting the connection between the suction cleaning device 1 and the base station 2 and causing the drive mechanism to operate. The sealing elements 8, 9 preferably have corresponding connecting elements, such as locking elements or shape-fitting elements, which ensure that the sealing elements 8, 9 are fixed relative to each other and pivot together in time and space to the open position. The drive mechanism can be, for example, a motor arranged in the base station 2, which is sufficiently strong to pivot both the sealing element 8 of the suction cleaning device 1 and the sealing element 9 of the base station 2. For this purpose, the sealing element 8 is preferably locked to the sealing element 9 or otherwise fixed. For example, it can also be specified that the sealing elements 8, 9 have corresponding magnetic elements integrated into the surface of the outer side 11 of the sealing elements 8, 9. Therefore, the sealing elements 8, 9 preferably pivot simultaneously to the open position that allows the suction chamber 4 to be regenerated. However, alternatively, in principle, the closing elements 8 and 9 can be pivoted sequentially to the open position over time, which typically requires two separate drive mechanisms. For example, to allow the pivoting movement of closing element 8 to follow that of closing element 9, they have spatially corresponding pivot axes 13 and 14. Possible implementations range from... Figure 5 and Figure 6 I learned this from the middle.

[0035] For example, by Figure 6The housing of the suction cleaning device 1 has a recess 17 into which a portion of the pivot axis 14 of the base station 2, having a sealing element 9, can be introduced. When the suction cleaning device 1 is positioned on the base station 2 as intended, the portion of the base station 2 having the pivot axis 14 engages with the recess 17 until the pivot axis 14 forms a straight extension of the pivot axis 13 of the sealing element 8 of the suction cleaning device 1. The bearing 15 of the suction cleaning device 1 is, for example, directly adjacent to the bearing 16 of the base station 2. At least essentially, the bearings 15 and 16 are positioned relative to each other, the appropriately associated pivot axes 13 and 14 are aligned with each other, and thus the sealing elements 8 and 9 of the suction cleaning device 1 and the base station 2 can pivot coaxially. To ensure that the sealing elements 8 and 9 are also hermetically abutting each other with their outer sides 11 and to prevent the suctioned material from flowing around the subsequently opened regeneration channel 6, at least one of the outer sides 11 has a sealing element 19 at least in the edge region. The sealing element 19 can, in principle, be arranged on the sealing element 8 of the suction cleaning device 1, or on the sealing element 9 of the base station 2. It is also recommended that the sealing element 19 seal between the sealing elements 8 and 9 and the inner wall 12 of the regeneration channel 6.

[0036] according to Figure 5 In the embodiment shown, the regeneration channel 6 of the base station 2 has a channel recess 10 into which two sealing elements 8 and 9 pivotally enter in a pivotally open position. The outer sides 11 of the outer walls of the corresponding housing surfaces of the suction cleaning device 1 or the base station 2, formed by the sealing elements 8 and 9 when the suction cleaning device 1 and the base station 2 are not interconnected, abut against each other and are sealed to each other by means of a sealing element 19 disposed between them. Furthermore, the sealing element 8 has a protrusion of the sealing element 19 (or a separate sealing element 19) at least in the edge region leading to the adjacent inner wall 12 of the regeneration channel 6. Thus, the suction material flowing along the regeneration channel 6 cannot reach either the channel recess 10 or the space between the sealing elements 8 and 9. This effectively prevents the outer side 11, which the user may frequently come into contact with during normal suction operation of the suction cleaning device 1, from being contaminated by the suction material.

[0037] In the embodiment shown here, the two sealing elements 8 and 9 open simultaneously and pivot coaxially toward the base station 2. Alternatively, the mutually abutting sealing elements 8 and 9 can also open together toward the suction cleaning device 1. Another embodiment, not shown here, can specify that the pivot axes 13 and 14 are not aligned with each other, but rather the pivot axes 13 and 14 and the sealing elements 8 and 9 are spatially separated from each other. The sealing element 8 of the suction cleaning device 1 can, for example, pivot toward the base station 2, while the sealing element 9 of the base station 2 pivots toward the suction cleaning device 1. Importantly, the corresponding outer sides 11 of the sealing elements 8 and 9 are sealed against the inner wall 12 and preferably additionally sealed relative to the inner wall 12 by sealing elements 19, so that the suction material cannot reach the outer sides 11 of the sealing elements 8 and 9. The suction material is then transferred, for example by means of a fan (not shown) of the base station 2, into the base station chamber 7 of the base station 2, without contamination of the outer sides 11 of the sealing elements 8 and 9. After the regeneration process is completed, the fan stops and the sealing elements 8 and 9 are transferred back to the base station chamber 7 of the base station 2. Figure 3 The closed position is shown. This can be achieved, for example, by disabling the corresponding drive mechanism and pivoting the closing elements 8, 9 back, for example, by the restoring force of one or more spring elements. The flow connection between the suction cleaning device 1 and the base station 2 is then disconnected. The closing of the closing elements 8, 9 can be performed simultaneously or sequentially at staggered times. Next, the suction cleaning device 1 can be separated from the base station 2 again.
