Description

Technical Field

[0001] The invention relates to an adapter device for a suction device, and a cleaning assembly. Background Art

[0002] Suction devices with a cleaning function (so-called suction cleaning devices) are known in the prior art, some of which are configured as dry vacuum cleaners, others as wet vacuum cleaners, and still others as combined dry / wet vacuum cleaners. Typically, dry vacuum cleaners are mainly used in households, as they are relatively cheap and are also available in a variety of forms on the market. They are also suitable for commercial cleaning, such as room cleaning in hotels. However, there are also some suction devices that are not intended for cleaning. Therefore, the suction device can also be generally referred to as a suction source.

[0003] If liquids or moist air are sucked in with a dry vacuum cleaner, this can cause a number of problems. Liquids can get into the suction turbine of the dry vacuum cleaner and damage it. In general, the liquid can also include water. In addition to the suction turbine, the liquid can also come into contact with other electrical components of the dry vacuum cleaner. This can cause damage to the electrical components or malfunctions. In addition, liquids in contact with electrical components can pose a safety hazard to the operator. In addition, dry vacuum cleaners usually include an air filter located upstream of the suction turbine to remove impurities, such as dust, etc. from the air before the air sucked in by the suction turbine is sent to the suction turbine. If the air filter comes into contact with liquid, or if moisture from the intake air accumulates inside it, the filter can be damaged.

[0004] The above problems mean that dry vacuum cleaners cannot be used for wet vacuuming or combined wet / dry vacuuming.

[0005] However, there are situations where it is also advantageous to suck in liquid or moist air. For example, some surfaces to be cleaned need to be treated with a liquid in order to achieve a good cleaning result. However, after the treatment is completed, the liquid applied to the surface to be cleaned, together with the dirt it has absorbed, often has to be removed from the surface to be cleaned. Imagine cleaning up after a flood, where it is often necessary to remove a mixture of water and dirt from parts of a building, especially a basement. The removal should be done as quickly as possible to minimize damage to the structure of the building. Typical dry vacuum cleaners are not suitable for all of the above applications. For example, in a domestic environment, wet vacuum cleaners or combined wet / dry vacuum cleaners are usually not available. This is also due to their high acquisition costs and their generally cumbersome design. In the event of a flood, wet vacuum cleaners or combined wet / dry vacuum cleaners are often not available in time due to the sudden surge in demand, and the wet vacuum cleaners or combined wet / dry vacuum cleaners that are available for purchase will quickly sell out.

[0006] When cleaning hotel rooms, they are usually cleaned with a dry vacuum cleaner. Bathrooms and wet rooms, on the other hand, are only cleaned with a dry vacuum cleaner if it is ensured that no moisture is sucked in. However, especially for cleaning wet rooms, it is advantageous to also be able to suck in liquids or a mixture of liquid and / or air. Summary of the invention

[0007] Therefore, the object of the present invention is to provide a simple solution for sucking liquids.In addition, the object of the present invention is also to provide a cost-effective solution for sucking liquids.

[0008] At least one of the above objects is achieved by an adapter device according to claim 1 and a cleaning assembly according to claim 15. The dependent claims relate to advantageous embodiments of the invention.

[0009] The present invention relates to an adapter device for a suction device, in particular a suction cleaning device, the adapter device comprising: a first turbine assembly, which can be driven by a primary suction air flow of the suction device; a second turbine assembly, which can be driven to generate a secondary suction air flow; and a transmission assembly, which is connected to the first turbine assembly and the second turbine assembly, wherein the driving of the first turbine assembly by the primary suction air flow can be used to drive the second turbine assembly via the transmission assembly to generate a secondary suction air flow.

[0010] According to the present invention, "utilizing" may include: the driving effect generated by the primary suction air flow at the first turbine assembly at least partially acts on and / or is transmitted to the transmission assembly, and the transmission assembly is configured to at least partially transmit the driving effect to the second turbine assembly to drive the second turbine assembly.

[0011] The present invention enables the use of a primary suction air flow as a driving source to generate a secondary suction air flow. At the same time, there are two different suction air flows. While the primary suction air flow therefore has the function of driving the primary turbine assembly (wherein based on this function, the secondary suction air flow is generated by driving the second turbine assembly through the transmission assembly), the secondary suction air flow has the function of sucking or picking up the suction medium (Saugsubstrat) from the surface to be cleaned. The suction medium may include solid matter such as dust or dirt particles, and may also include liquid and / or moisture. Of course, before the suction medium is conveyed to the secondary turbine assembly, it is preferably separated from the secondary suction air flow or at least partially by the secondary suction air flow to avoid damage to the secondary turbine assembly. Therefore, the secondary turbine assembly can be configured to extract air through a secondary suction air flow received from a collection container (which is configured to receive liquid). In general, the collection container can be configured to at least partially retain the suction medium.

[0012] The invention makes it possible to provide a dry vacuum cleaner as a suction device, whereby liquids and / or moist air can be sucked in by the dry vacuum cleaner. The adapter device separates the primary suction air flow from the secondary suction air flow, thereby preventing the vacuum cleaner from being damaged by the suction medium, in particular moist air and / or liquid. This also prevents the risk of a short circuit in the dry vacuum cleaner.

[0013] According to one embodiment of the invention, the adapter device further comprises a barrier component, which provides at least one liquid barrier between the first turbine component and the second turbine component. The barrier component can act as a splash shield, for example, to prevent liquid from the second turbine component from reaching the first turbine component. Therefore, such a barrier component may be arranged in a labyrinth-like manner. According to a related aspect of the invention, it can also be arranged that the barrier component separates the first turbine component and the second turbine component from each other in a substantially liquid-tight, particularly fluid-tight manner. This ensures that at least no liquid (especially no moisture) can be transferred from the first turbine component to the second turbine component. In this way, liquid can be prevented from entering the secondary suction air flow and possibly causing damage to the suction device. This fluid-tight separation means that there is no medium exchange between the second turbine component and the first turbine component. Therefore, the two suction air flows are completely separated from each other at least inside the adapter device. This can ensure that the adapter device is extremely safe and reliable to operate by adopting a dry suction device. In other words, the barrier component can be configured to separate the primary suction air flow and the secondary suction air flow from each other, so that substantially no liquid and / or moisture can enter the primary suction air flow from the secondary suction air flow. According to one embodiment of the present invention, it can also be arranged that: the barrier assembly includes a sealing assembly. The sealing assembly can include a labyrinth sealing device.

[0014] According to one aspect of the invention, the barrier assembly may be configured to at least partially support or at least partially form the transmission assembly. This enables a compact design of the adapter device.

[0015] According to an advantageous embodiment of the present invention, the adapter device also includes a primary connection interface, which is configured to be connected to the suction device for driving the first turbine assembly by the primary suction air flow. It can also be arranged that the primary connection interface is configured to be able to adapt the suction device, especially in terms of geometry and / or size. To this end, a regulating mechanism can be provided, which can be activated to change the geometry or size of the primary connection interface. Additionally or alternatively, the primary connection interface can have a plurality of interface parts for connecting with the corresponding suction device. These interface parts can have different geometries and / or sizes. In general, these embodiments enable corresponding components or connectors of suction devices of different geometries to be connected to the primary connection interface. In this way, the adapter device can be connected to a variety of suction devices available on the market, or it can be compatible with these suction devices. This means that the adapter device can achieve universal connection with various suction devices. The primary connection interface can include a thread, a bayonet lock, a clamping mechanism, a screw connection, etc.

[0016] Additionally or alternatively, it can also be provided that the adapter device can be coupled to a primary connection module, wherein the primary connection module has the above-mentioned primary connection interface. Therefore, a connection piece with a predetermined geometric shape can be provided on the adapter device to couple with the primary connection module. Due to the presence of the connection piece, the structure of the adapter device remains simple, but through the primary connection module, the adapter device can still be coupled or compatible with a plurality of suction devices.

[0017] According to one embodiment of the present invention, it can also be arranged that the transmission component connects the first turbine component to the second turbine component in a mechanical, pneumatic, hydraulic or electric manner or through a combination thereof, so as to drive the second turbine component by driving the first turbine component. For example, it can be arranged that the transmission component is configured to generate electrical energy based on driving the first turbine component, so that the second turbine component can be driven by the electrical energy. Therefore, the transmission component can have a corresponding generator and a corresponding motor drive device. In addition, the transmission component can be configured so that: driving the first turbine component causes the fluid (such as hydraulic oil) in the transmission component to move, wherein the transmission component is also configured to generate electrical energy based on the movement of the fluid. to drive the second turbine assembly.

[0018] According to one embodiment of the present invention, it can also be arranged that the transmission assembly includes a shaft, and the first turbine assembly is configured to drive the shaft, and the shaft is configured to drive the second turbine assembly to generate a secondary suction air flow. The shaft can be driven directly or indirectly. In addition, the second turbine assembly can also be driven directly or indirectly. Therefore, according to the direct drive, it can be arranged that the shaft connects the first turbine assembly with the second turbine assembly, in particular rigidly connects them to each other. For example, the indirect drive device includes a clutch and / or a gearbox, in particular having a speed increase or speed decrease function ( Untersetzungsfunktion).

[0019] According to one embodiment of the present invention, it can also be arranged that the barrier component at least partially supports the shaft. This enables the barrier component to have additional functions. In general, this is conducive to making the design of the adapter device compact.

[0020] According to an advantageous embodiment of the invention, it can be provided that the first turbine assembly comprises a primary turbine wheel configured to rotate about a primary rotation axis; and the second turbine assembly comprises a secondary turbine wheel configured to rotate about a secondary rotation axis, wherein the primary rotation axis and the secondary rotation axis are arranged substantially parallel to or coincident with each other. Merely for the sake of clarity, it is necessary to mention that the primary turbine wheel can be driven by a primary suction air flow, while the secondary turbine wheel is configured to generate a secondary suction air flow. According to a preferred embodiment of the invention, the primary rotation axis and the secondary rotation axis are coincident, i.e. coincident. Therefore, this embodiment relates to a special form of parallelism, i.e. a coincident arrangement of the two rotation axes. This enables a particularly compact design of the adapter device.

[0021] In this case, it can be provided that, when the second turbine assembly is driven, the secondary suction air flow initially flows parallel to the secondary rotation axis in order to be supplied to the secondary turbine impeller and then flows in a radial direction opposite to the secondary rotation axis in order to flow out of the secondary turbine impeller. The movement of the secondary turbine impeller thus acts as an additional barrier between the secondary suction air flow and the primary suction air flow, in particular to prevent the passage of liquid and / or moisture. This is due to centrifugal forces, which, during the driving of the secondary turbine impeller, act on any liquid and / or moisture and / or dirt that may adhere to the secondary turbine impeller and carry these substances away from the secondary turbine impeller in a radial direction. Alternatively, the secondary suction air flow can then also flow parallel to the rotation axis or at any angle relative to the rotation axis in order to flow out of the secondary turbine impeller. Furthermore, it can also be provided that the secondary suction air flow flows out in a predetermined angular range around the secondary rotation axis. Preferably, the primary suction air flow enters the adapter device outside this angular range and flows to the primary turbine impeller.

[0022] According to one embodiment, it can be provided that the adapter device has a reduction ratio or transmission ratio. This can be provided in the transmission assembly. For this purpose, a gearbox can be provided, which converts a certain rotational speed of the first turbine assembly into a different rotational speed required by the second turbine assembly. However, the reduction ratio or transmission ratio can also be produced by different designs of the turbine wheels of the turbine assemblies, for example, by different blade geometries of the turbine wheels or different sizes of the turbine wheels.

[0023] According to an advantageous embodiment of the invention, the adapter device comprises an actuatable valve assembly configured to adjust the proportion of the primary suction air flow acting on the first turbine assembly. The actuatable valve assembly can be configured as a throttle valve. The actuatable valve assembly enables the adapter device to be coupled to suction devices of different suction powers or different suction air flows. For example, if the suction power of the suction device is very high, the valve assembly can be at least partially opened so that only a portion of the primary suction air flow acts on the first turbine assembly. In the case of a suction device with a lower suction power, the valve assembly can be completely or nearly completely closed. The valve assembly can be actuated in such a way that it adjusts the proportion of the primary suction air flow acting on the first turbine assembly according to the intensity of the primary suction air flow. It is conceivable that a spring assembly can open or close the flap on the valve assembly according to the intensity of the primary suction air flow. The term "intensity" can include a pre-set volume flow. In addition to the spring assembly, other at least partially automated mechanisms can also be provided.

[0024] According to an advantageous embodiment of the invention, the adapter device further comprises a secondary connection interface for coupling the adapter device to a module, wherein in the coupled state the secondary suction air flow can at least partially be discharged from the module. The module preferably comprises a collecting container for collecting liquids and / or dirt, but may also comprise an inlet pipe, a floor unit or a cleaning tool. The secondary connection interface may comprise a thread, a bayonet lock, a clamp lock, a screw joint or the like.

[0025] According to one embodiment of the invention, it can be provided that a module, from which the secondary suction air flow can be discharged, is formed integrally with the adapter device. For example, such a module can comprise a collecting container for collecting liquids and / or dirt.

[0026] According to an embodiment of the invention, the adapter device further comprises a collecting container for collecting liquid and / or dirt.

[0027] According to one embodiment of the invention, the adapter device further comprises at least a first electrical contact assembly for supplying electric current to the adapter device, wherein the adapter device preferably further comprises a second electrical contact assembly for at least partially transferring the electric current to a module coupled to the adapter device, for example, the module comprises a cleaning tool, which may be driven by an electric motor or by electric current.

[0028] According to one embodiment of the present invention, the adapter device includes a generator, which is configured to generate current to provide current to a module (such as a tool, etc.) connected to the adapter device. To this end, at least one connector for releasing current can be formed on the adapter device. The generator can be driven by a primary suction air flow or a secondary suction air flow. For example, the generator is capable of generating a voltage level of 12 volts or 24 volts. This voltage level is different from the voltage level of a conventional suction device that usually operates at 230 volts. However, this voltage level is not too dangerous and is usually used to power tools or sensors.

[0029] According to an advantageous aspect of the invention, a receiving interface for connecting to an additional energy source (preferably a battery) can be further provided on the adapter device. This makes it possible to provide additional energy, such as electric current, to the adapter device. For example, such provided energy can be used to supply energy to a module connected to the adapter device (e.g. a cleaning tool that can be driven by an electric motor).

[0030] According to one embodiment of the present invention, the adapter device further comprises a handle assembly, which is formed on the adapter device or can be coupled to the adapter device and is configured to be actuated by an operator to move the adapter device, which facilitates the operator to operate the adapter device.

[0031] According to an embodiment of the present invention, the adapter device further comprises a housing, wherein the first turbine assembly and / or the second turbine assembly and / or the transmission assembly are at least partially surrounded by the housing.

[0032] According to one embodiment of the invention, the housing comprises at least a first housing part and a second housing part, which are configured such that they can be coupled to each other. For example, the housing parts can be coupled to each other by means of a bayonet lock or a threaded screw joint. The two housing parts facilitate assembly and maintenance of the adapter device. Thus, the housing can be of modular design.

[0033] According to one embodiment of the invention, the adapter device has a modular structure. For example, the first turbine assembly and / or the second turbine assembly and / or the transmission assembly and / or the housing or the housing part can form a module. It can also be further provided that the modules are configured to be detachably connected to each other. This modular design and the ability to be connected together make assembly simple. In addition, the adapter device is easy to disassemble for cleaning, maintenance or replacement of spare parts. In addition, for example, the turbine impeller of the turbine assembly can be easily replaced so that the adapter device can be adapted to suction sources with different suction powers.

[0034] According to one aspect of the invention, it can be arranged that the transmission component and / or the second turbine component and / or the first turbine component are configured to be able to be started and deactivated, in particular to be able to be controlled. To this end, a control system can be provided, by which, for example, the transmission component can be started and deactivated. In addition, a sensor component can be provided, whereby the transmission component and / or the second turbine component and / or the first turbine component can be started and deactivated based on a signal from the sensor component. The sensor can be a level sensor for measuring the level of the suction medium in the collection container. Additionally or alternatively, a humidity sensor can be provided as a sensor. For example, the signal can indicate that a predetermined humidity value in the secondary suction air flow has been exceeded. Additionally or alternatively, an inclination sensor can be provided as a sensor.

[0035] According to one embodiment of the present invention, the adapter device may have at least one tertiary connection interface, whereby the secondary suction air flow can be at least partially discharged through the tertiary connection interface. For example, the tertiary connection interface can be configured to be connected to a hose. Therefore, it can include a suction joint. In this way, the air and / or liquid sucked by the secondary suction air flow (i.e., the suction medium) can be at least partially discharged through the tertiary connection interface and sent to the hose for discharge. It is particularly advantageous that before entering the adapter device, the suction medium has not been completely discharged or only partially discharged from the secondary suction air flow. Even so, the suction medium cannot enter the primary suction air flow and the suction device. It is envisioned that liquid can be sucked through the adapter device and can be discharged from the adapter device through the tertiary connection interface. In this way, a suction medium such as a liquid can be sucked into the adapter device and can be discharged again in a controllable manner. In this way, a large amount of liquid can be sucked and discharged in a specific way, which is often necessary after an event such as a flood. Instead of or in addition to the tertiary connection interface, a module such as a hose can also be formed integrally with the adapter device for discharging the suction medium.

[0036] The present invention also relates to a cleaning assembly, which comprises:

[0037] - an adapter device of one of the above-mentioned types; and

[0038] A suction device coupled to the first turbine assembly for generating a primary suction air flow.

[0039] The suction device can be configured as a suction cleaning device, in particular as a dry vacuum cleaner. For example, the suction device can be a handheld vacuum cleaner or a conventional vacuum cleaner. The suction device can be operated by a storage battery.

[0040] The adapter device can be permanently installed in the cleaning component, and / or can be formed integrally with the cleaning component. Alternatively, the adapter device can be configured as an interchangeable module of the cleaning component. In general, it should be pointed out that the term "adapter" should be understood in a broad sense, and in addition to referring to a modular design connected to other components through an interface, it also includes an integrated design. "Integrated" refers to a component with one or more other components or modules. In addition, when the term "interface" is used, the components connected to each other through the "interface" can also adopt an integral design rather than a connectable design.

[0041] One aspect relates to a cleaning assembly for sucking a suction medium by a suction device, the cleaning assembly comprising:

[0042] - an adapter device, the adapter device comprising:

[0043] a first turbine assembly, the first turbine assembly being drivable by a primary suction air flow of the suction device,

[0044] a second turbine assembly which can be driven to generate a secondary suction air flow in order to draw in the suction medium, and

[0045] A transmission assembly coupled to the first turbine assembly and the second turbine assembly, wherein:

[0046] The primary suction air flow drives the first turbine assembly via the transmission assembly for driving the second turbine assembly to generate a secondary suction air flow;

[0047] as well as

[0048] - at least one collecting container assembly, which is configured to separate and collect the suction medium sucked in by the secondary suction air flow.

[0049] “Utilizing” may include: the driving effect generated by the primary suction air flow at the first turbine assembly at least partially acts on and / or is transmitted to the transmission assembly, and the transmission assembly is configured to at least partially transmit the driving effect to the second turbine assembly to drive the second turbine assembly.

[0050] According to this aspect, the primary suction air flow can be used as a driving source to generate a secondary suction air flow. At the same time, there are two different suction air flows. While the primary suction air flow therefore has the function of driving the primary turbine assembly (wherein based on this function, the secondary suction air flow is generated by driving the second turbine assembly through the transmission assembly), the secondary suction air flow has the function of sucking or picking up the suction medium from the surface to be cleaned. The suction medium may include solid substances such as dust or dirt particles, and may also include liquids and / or moisture. Of course, before the suction medium is delivered to the secondary turbine assembly, it is preferably separated from the secondary suction air flow or at least partially by the secondary suction air flow to avoid damage to the secondary turbine assembly. Therefore, the second turbine assembly can be configured to extract air from the collection container assembly or the collection container of the collection container assembly through the secondary suction air flow. The collection container assembly or the collection container is configured to separate the suction medium from the secondary suction air flow and at least partially collect the suction medium.

[0051] The invention makes it possible to provide a dry vacuum cleaner as a suction device, so that liquids and / or moist air can be sucked in through the dry vacuum cleaner. The adapter device separates the primary suction air flow from the secondary suction air flow, so that damage to the vacuum cleaner due to the suction medium, in particular moist air and / or liquid, can be avoided. In this way, the suction device sucks in the primary suction air flow instead of the secondary suction air flow. In this way, the risk of short-circuiting the dry vacuum cleaner can also be avoided.

[0052] The cleaning assembly is a compact and inexpensive solution which makes it possible to use a dry vacuum cleaner to suck up a suction medium comprising liquids and / or moist air. The suction medium is separated from the secondary suction air flow and collected in a collecting container. There is therefore no risk of moist or wet suction medium coming into contact with the dry vacuum cleaner, since the primary suction air flow and the secondary suction air flow are structurally separated from one another in the adapter device.

[0053] According to one embodiment, it can be provided that the collecting container assembly is configured such that it can be coupled to the adapter device. For example, it can also be provided that the collecting container assembly can be separated from the adapter device. For example, for the purpose of transport, storage, emptying the collecting container assembly or maintenance, the cleaning assembly can be disassembled into several smaller individual components.

[0054] According to one embodiment, it can be provided that in the coupled state the adapter device and the collecting container assembly are fixedly, in particular rigidly, connected to one another. This enables a simple transmission of forces between the adapter device and the collecting container assembly.

[0055] According to one embodiment, it can be provided that the adapter device and the collecting container assembly are configured as an integral part. In other words, the adapter device and the collecting container assembly are permanently coupled to each other and structurally connected to each other. This enables a very compact design of the cleaning assembly. Furthermore, the adapter device and the collecting container assembly then form a structural unit.

[0056] According to an alternative embodiment, the cleaning assembly may further comprise a hose assembly configured to couple the adapter device to the collection container assembly. This makes it possible to arrange the adapter device to be separated from the collection container assembly, whereby the secondary suction air flow can still be discharged from the collection container assembly to the adapter device. For example, the adapter device may be carried by an operator in the form of a backpack, while other components of the cleaning assembly (e.g., the collection container assembly or the cleaning tool) may be actuated, in particular displaced, by the operator. Thus, the portion to be operated by the operator is relatively light.

[0057] According to one aspect, it can be provided that the collecting container assembly and / or the adapter device comprises a rotational geometry.

[0058] According to one aspect, it can be arranged that the collecting container assembly is roughly configured to have a tubular, in particular cylindrical shape. This facilitates a particularly compact design. In addition, such a tubular design can reduce the number of internal corners and edges. This reduces the risk that certain components of the suction medium are deposited on the corners and edges of the collecting container assembly. In addition, such a tubular design facilitates gripping by the operator. In addition to the tubular design, other geometric shapes or combined designs can also be provided. These shapes include spherical, cuboid, cubic, prism, cylindrical, pyramidal, conical or other polygonal bodies and extrudable bodies. In general, tubular refers to the provision of an elongated hollow body configured to carry a certain medium.

[0059] According to one aspect, it can be provided that the length of the collecting container assembly is a multiple of its height and / or width and / or diameter. Preferably, this ratio is at least 5:1, particularly preferably at least 8:1.

[0060] According to one embodiment, it can be provided that the collecting container assembly comprises at least one viewing window. This enables an operator to view the conditions inside the collecting container assembly, for example to be able to identify the filling level of the suction medium in the collecting container assembly. This also enables an operator to more easily identify when the collecting container assembly needs to be emptied.

[0061] According to one embodiment, it can be provided that the collecting container assembly or the collecting container at least partially comprises a transparent material. For example, the collecting container assembly can also be made completely of a transparent material. This also enables an operator to view the interior of the collecting container assembly, for example to be able to recognize the filling level of the suction medium in the collecting container assembly. This also enables an operator to more easily recognize when the collecting container assembly needs to be emptied.

[0062] According to one aspect, the collecting container assembly comprises an emptying opening, which enables the suction medium to be discharged from the collecting container assembly. A cover assembly can be provided, which enables the emptying opening to be opened or closed. Additionally or alternatively, the collecting container assembly can be emptied via an interface, through which the collecting container assembly is connected or can be connected to the adapter device.

[0063] According to one aspect, it can be arranged that the collecting container assembly and / or the adapter device are configured as a support structure for the cleaning assembly. This allows the design of the cleaning assembly to have extremely high stability. For example, forces and / or torques can be transferred from one area of ​​the collecting container assembly to another area of ​​the collecting container assembly. This can facilitate cleaning using the cleaning assembly. This is because, if a cleaning tool is also coupled to the collecting container assembly, the cleaning tool can also be moved by moving the collecting container assembly. Additionally or alternatively, it can be arranged that the adapter device or the cleaning assembly includes a load-bearing structure that can be coupled to the collecting container assembly.

[0064] According to one embodiment, it can be arranged that the collection container assembly and / or the adapter device are configured so that their positions can be changed, in particular, can be tilted. The collection container assembly can be configured so that its position can be changed, in particular tilted, together with other parts of the cleaning assembly and / or individually. This makes it easy to manipulate the collection container assembly and / or the adapter device. The position of the collection container assembly and / or the adapter device can be changed so that it can pivot in one plane, two planes and / or multiple planes. In addition, the ability to pivot around one or more pivot axes or pivot points can also be provided. These planes, pivot axes or pivot points may be fixed or variable relative to the position of the collection container assembly and / or the adapter device. These planes and / or pivot axes can be aligned orthogonally to each other or at a preset angle. When the term "position adjustable" or "pivotable" is mentioned in this article, this can also include tiltable or deflectable situations. The term "position adjustable" can refer to a simple translation change that does not include a position. Thus, “position-adjustable” can be defined as one or more rotational changes in position or a combined translational and translatory change in position.

[0065] According to one aspect, it can be arranged that the cleaning assembly includes a closing body, which is configured to be able to close the passage through which the primary suction air flow or the secondary suction air flow passes during operation when in the closed position. In addition, in the open position, the closing body can be configured to release the primary suction air flow or the secondary suction air flow. In the case of the secondary suction air flow, the closing body in the closed position can reliably ensure that the suction medium (especially liquid) does not escape from the collection container assembly into the second turbine assembly. In this way, the cleaning assembly can also be stored and moved safely. When the suction medium in the collection container assembly reaches a predetermined level or a predetermined amount, the closing body can be configured to be in the closed position. In the case of the primary suction air flow, the closed position can reliably ensure that even if the two suction air flows are separated, no suction medium can accidentally reach the suction device.

[0066] According to another aspect, the cleaning assembly includes a force actuator for generating an actuating force, by which the closing body can be pushed into a closed position and / or an open position. The force actuator may include a magnetic force for generating an actuating force. The force actuator may be turned on and / or off. The force actuator may be controllable. Preferably, the force actuator is controlled or activated and / or deactivated according to a control signal. The control signal may be based on a signal from a sensor (e.g., an inclination sensor and / or a liquid level sensor, etc.) of the collection container assembly.

[0067] According to one embodiment, the cleaning assembly comprises a control assembly configured to control at least the force actuator. Preferably, the control assembly is configured to perform control operations based on a signal, such as a signal from a level sensor in the collection container assembly for measuring the level of the suction medium, a signal from a tilt sensor, such as a signal for measuring the tilt of the collection container assembly, etc.

[0068] According to one embodiment, the cleaning assembly includes at least one handle assembly configured to be held by an operator and configured to be fixedly coupled to or capable of being fixedly coupled to an adapter device and / or a collection container assembly. This enables the operator to more easily manipulate the cleaning assembly. This can facilitate the use of the cleaning assembly and can also facilitate its manipulation in other situations besides manipulation, such as manipulation during transportation or storage. This connectable configuration enables the operator to use the handle assembly when it is actually beneficial to the operator and remove the handle assembly when it is not needed. The case of permanent connection can include an integral composition.

[0069] According to one embodiment, it can be arranged that the handle assembly for coupling has an actuable connection mechanism, which is configured to couple the handle assembly to the adapter device and / or the collection container assembly and / or to disconnect the handle assembly from the adapter device and / or the collection container assembly when actuated. This allows the handle assembly to be easily attached or removed. This enables the operator to use the handle assembly only when it is actually beneficial. For example, if the cleaning assembly is stored, the handle assembly can be easily removed, thereby keeping the cleaning assembly compact.

[0070] According to another embodiment, it can be arranged that the handle assembly comprises a handle portion that can be gripped by a user and a handle base portion that is configured to be coupled to the adapter device and / or the transmission assembly, wherein the position of the handle portion relative to the handle base portion is adjustable. This enables an operator to more easily adjust the handle assembly to an ergonomic position. When the cleaning assembly is retracted, the handle assembly can be retracted to a compact position.

[0071] According to one embodiment, it can be arranged that the cleaning assembly further comprises a tool connection interface for connecting to a cleaning tool, whereby the secondary suction air flow can be discharged from the cleaning tool via the tool connection interface. The tool connection interface makes it possible to connect different cleaning tools to the cleaning assembly. This makes the cleaning assembly multi-purpose.

[0072] Advantageously, the tool connection interface is arranged on the collection container assembly or on a tool connection module connected to the collection container. In this way, the sucked suction medium can be directly supplied to the collection container assembly. In general, the design of the cleaning assembly is therefore more compact.

[0073] According to one embodiment, it can be arranged that the tool connection interface includes an electrical contact assembly, which is configured to establish electrical contact with the cleaning tool. For example, such electrical contact can be used to transmit sensor signals from the cleaning tool or to the cleaning tool. In addition, the cleaning tool can also be provided with current through the electrical contact assembly, for example, to drive the motor to operate, in particular to drive the cleaning tool such as a cleaning brush or a roller to operate.

[0074] According to one embodiment, it may be provided that the tool connection interface is configured to couple the cleaning tool or a part of the cleaning tool in a substantially rigid manner. This enables forces to be transmitted to the cleaning tool during operation.

[0075] According to one aspect, it can be provided that the cleaning assembly comprises at least one power supply interface for establishing electrical contact with a power source. Advantageously, the power supply interface is arranged on the adapter device or the collection container assembly. The power supply interface enables additional electrical energy to be provided by the power source. This can be used, for example, to operate a cleaning tool coupled to the cleaning assembly.

[0076] According to one embodiment, it may be provided that the power supply interface includes a holder assembly configured to detachably accommodate the battery.

[0077] According to one embodiment, the cleaning assembly includes a primary connection interface for connecting to a suction device, whereby the primary suction air flow can be discharged from the adapter device through the primary connection interface to drive the first turbine assembly. It can be arranged that the primary connection interface is configured to be particularly adapted to the suction device in terms of geometry and / or size. To this end, a regulating mechanism can be provided, which can be actuated to change the geometry or size of the primary connection interface. Additionally or alternatively, the primary connection interface can have a plurality of interface portions to be connected to the corresponding suction device. These interface portions can have different geometries and / or sizes. In general, these embodiments enable corresponding components or connectors of suction devices of different geometries to be connected to the primary connection interface. This enables the adapter device to be connected to a variety of suction devices available on the market, or to be compatible with these suction devices. This means that the adapter device can achieve universal connection with various suction devices. The primary connection interface can include a thread, a bayonet lock, a clamping mechanism, etc.

[0078] According to one embodiment, it can be provided that the primary connection interface is configured to couple the suction device to the adapter device in a substantially rigid manner. This enables power transmission between the suction device and the adapter device. If the secondary connection interface and the collecting container are also rigid, a rigid unit can be formed. This makes handling easier.

[0079] According to one embodiment, the cleaning assembly further comprises a hose assembly, which is coupled to the adapter device for guiding the primary suction air flow. Preferably, the hose assembly is coupled to the primary connection interface. The hose assembly enables the suction device to be arranged separately and displaceably relative to the adapter device. For example, the suction device can be carried by an operator, such as in the form of a backpack. The primary suction air flow can then be discharged from the adapter device through the hose assembly. Therefore, the cleaning assembly remains relatively light and easy to operate for the operator. Preferably, the hose assembly is elastic.

[0080] According to one embodiment, the cleaning assembly further comprises a hose assembly, which couples the adapter device and the collection container assembly to guide the primary suction air flow. Preferably, the hose assembly is coupled to the primary connection interface. The hose assembly enables at least the adapter device to be arranged separately and displaceably relative to the collection container assembly. For example, the adapter device can be carried together with the suction device by the operator, such as in the form of a backpack. The primary suction air flow can then be discharged from the collection container assembly through the hose assembly. Therefore, the portion of the cleaning assembly carried by the operator's arm remains relatively light. Preferably, the hose assembly is elastic.

[0081] According to one embodiment, the cleaning assembly comprises at least one clean water tank for holding clean water. Clean water refers to a liquid, in particular water, intended for cleaning and preferably uncontaminated. Cleaning substances such as soap, detergents, etc. may be added to the clean water. Preferably, the cleaning assembly comprises a water distribution assembly, which is configured to supply clean water from the clean water tank to the surface to be cleaned. For this purpose, an operable valve may preferably be provided in the water distribution assembly so that an operator can adjust the amount of water distributed.

[0082] According to one embodiment, the collection container assembly includes a standpipe configured to at least partially direct the secondary suction air flow into the collection container assembly.

[0083] The advantages, features and embodiments explained for the adapter device also apply to the cleaning component and vice versa. BRIEF DESCRIPTION OF THE DRAWINGS

[0100] Figure 1 is a schematic illustration of an adapter device 10 for a suction device according to the present invention. The adapter device 10 comprises a first turbine assembly 12, which can be driven by a primary suction air flow 14. The adapter device 10 also comprises a second turbine assembly 16, which can be driven to produce a secondary suction air flow 18. The adapter device 10 also comprises a transmission assembly 20, which is coupled to the first turbine assembly 12 and the second turbine assembly 16. The transmission assembly 20 is configured so that the second turbine assembly 16 can be driven by driving the first turbine assembly 12 by the primary suction air flow 14 to produce the secondary suction air flow 18.

[0101] “Capable of being utilized” may mean that the driving effect generated by the primary suction air flow 14 at the first turbine assembly 12 at least partially acts on and / or is transmitted to the transmission assembly 20, and the transmission assembly 20 is configured to at least partially transmit the driving effect to the second turbine assembly 16 to drive the second turbine assembly.

[0102] The adapter device 10 includes a housing 22 that surrounds the first turbine assembly 12, the second turbine assembly 16, and the transmission assembly 20. The adapter device 10 also includes a barrier assembly 24 disposed within the housing 22 that divides the housing 22 into a first or upper housing portion 26 and a second or lower housing portion 28. The barrier assembly 24 extends through the schematically shown transmission assembly 20. The barrier assembly 24 provides a substantially fluid-impermeable barrier such that, for example, no fluid or gas exchange occurs between the two housing portions 26, 28, at least within the housing 22.

[0103] A primary connection interface 30 is arranged at the upper end of the first turbine assembly 12, and the primary connection interface is arranged to be connected with a suction device. For this reason, the primary connection interface 30 is arranged to have a circular cross section, but other shapes may also be adopted. For the sake of simplicity, the suction device is not shown here. However, the primary suction air flow 14 generated by the suction device and acting on the first turbine assembly 12 is shown in the figure. If the suction device is connected to the primary connection interface 26 and is in operation, thereby generating the primary suction air flow 14, then the primary suction air flow 14 will pass through the first turbine assembly 12 from the inflow opening 32 arranged on one side of the first turbine assembly 12, and leave the first turbine assembly 12 via the primary connection interface 30, and then flow into the suction device. In this process, the primary suction air flow 14 drives the first turbine assembly 12. The transmission assembly 20 is configured to be able to drive the second turbine assembly 16 by driving the first turbine assembly 12. To this end, as shown here, the transmission assembly 20 may include a shaft assembly 34 that mechanically couples the first turbine assembly 12 to the second turbine assembly 16, so that the mechanical movement of the first turbine assembly 12 (particularly the turbine impeller of the first turbine assembly 12) is transmitted to the second turbine assembly 16 (particularly the turbine impeller of the second turbine assembly 16) through the shaft assembly 34. The secondary suction air flow 18 is generated by driving the second turbine assembly 16. Therefore, the secondary suction air flow 18 is transmitted to the outflow opening 38 configured on the side of the housing 22 and the side of the second turbine assembly 16 through the secondary connection interface 36 configured on the second turbine assembly 16 at the lower end. In other words, driving the second turbine assembly 16 generates an inflow effect at the secondary connection interface 36, so that air (i.e., the secondary suction air flow 18) can be sucked in via the secondary connection interface 36. The secondary connection interface 36 is configured to be connected to a module, such as a suction pipe, a tool or a floor unit. In this example, the secondary connection interface 36 has a circular cross-section, but other shapes can also be used. The secondary suction air flow 18 can be used to suck in liquid or suction medium. The adapter device 10 can separate the primary suction air flow 14 from the secondary suction air flow 18. In this way, any suction medium, such as liquid or moisture, in particular, cannot enter the primary suction air flow 14 from the secondary suction air flow 18 and reach the suction device. However, the primary suction air flow 14 generated by the suction device can be used to generate the secondary suction air flow. With the help of the adapter device 10, the suction device (in the form of a dry vacuum cleaner) can be converted into a wet vacuum cleaner. If the suction medium (such as liquid) is to be sucked in through the adapter device 10 like a pump and discharged again, the outflow opening 38 can be configured as a connection interface, or a tertiary connection interface for a hose for discharging liquid. This makes it possible to suck in and discharge liquid in large quantities.

[0104] The housing 22 is cylindrical, but it can also be, for example, cuboid, circular, etc. In addition to the connection of the module via the secondary connection interface 36, a connection interface or a connection component (such as a thread or a bayonet lock) can also be provided on the housing 22 in order to discharge the secondary suction air flow from the module (such as a collecting container) for suctioning the suction medium.

[0105] Figure 2 1 is a schematic diagram of the adapter device 10 according to the present invention in a state of being coupled to the collecting container 40 of the collecting container assembly 41. The structure of the adapter device 10 is based on Figure 1 The structure shown in the figure has the following differences. Figure 2 As can be seen, the lower housing part 28 forms a collecting container 40 or a collecting container assembly 41. The first turbine assembly 12 is arranged in the larger upper housing part 26. Due to the increased size of the upper housing part 26, the primary connection interface 30 is configured on the pipe part 31 that connects the first turbine assembly 12 to the primary connection interface 30. A liquid collecting area 42 is provided in the collecting container 40. The secondary suction air flow 18 generates a negative pressure in the collecting container 40, so that a suction medium (in particular air and / or liquid and / or dirt, etc.) from the surface to be cleaned, for example, can be sucked in and introduced into the collecting container 40 via an inlet pipe (Ansaugrohrs) 44 arranged at the lower end of the housing 22. The liquid is separated in the liquid collecting area 42, so that only air can be discharged from the collecting container 40 via the secondary suction air flow 18. For this purpose, the inlet pipe 44 extends through and beyond the liquid collecting area 42, so that the outlet opening 46 of the inlet pipe 44 is arranged above the liquid collecting area 42. Furthermore, in the collecting container 40 , in the region between the outlet opening 46 and the second turbine assembly 16 , a splash protection barrier 48 is arranged, which in the form of a shield shields the outlet opening 46 at a certain distance therefrom and prevents the suction medium from flowing directly in the direction of the second turbine assembly 16 after leaving the inlet pipe 44 .

[0106] Figure 3 FIG. 1 is a schematic exploded view of another embodiment of an adapter device 110 according to the present invention. Figure 1 and Figure 2The mode of operation of the adapter device 10 shown, but with a special structure. The adapter device 110 has a first housing part 126, a first turbine assembly 112 with a primary turbine wheel 150, a barrier assembly 124, a second turbine assembly 118 with a secondary turbine wheel 152, a transmission assembly 120 including a rigid shaft 154, and a second housing part 128. The shaft 154 is arranged on an axis A, about which the shaft 154 rotates during operation. The shaft 154 is configured to receive a first ball bearing 156 and a second ball bearing 158 in its central cylindrical region, but other types of rolling bearings may also be provided in addition or alternatively. The ball bearings 156, 158 are arranged to radially and axially support the shaft 154 relative to the barrier assembly 124, wherein the shaft 154 is arranged to rotate relative to the barrier assembly. For this purpose, an opening 160 is provided on the barrier component 124, which is configured to receive the ball bearings 154, 156 and to contact the ball bearings on their outer circumferential surfaces. The barrier component 124 is substantially axisymmetric with respect to the axis A and symmetrical with respect to a central plane arranged substantially orthogonal to the axis A along its central axis, which coincides with the axis A. For this purpose, an interference fit can be provided. On both sides along the axis A, the shaft 154 with a smaller diameter is provided with outer circumferential geometries, not shown, which are configured to receive corresponding inner circumferential geometries, which are configured on the primary turbine impeller 150 and the secondary turbine impeller 152 and are also arranged along the axis A. These circumferential geometries are configured to form an interference fit, so that the rotation of the primary turbine impeller 150 or the secondary turbine impeller 152 can cause the shaft 154 to rotate, and vice versa. For example, as an alternative or in addition to a form fit, a non-form fit connection can also be used. At both ends of the shaft 154, an outer thread, also of smaller diameter, is provided, onto which a corresponding shaft nut 162, 164 can be screwed. The first shaft nut 162 is configured to axially fasten the primary turbine impeller 150 to the shaft 154, and the second shaft nut 164 is configured to axially fasten the secondary turbine impeller 152 to the shaft 154. The corresponding areas with outer circumferential geometry adjacent to the central cylindrical area form shoulders or stops relative to the respective central cylindrical areas, against which the first shaft nut 162 presses the primary turbine impeller 150, and against which the second shaft nut 164 presses the secondary turbine impeller 152, and the corresponding shoulders are used to arrange the primary turbine impeller 150 or the secondary turbine impeller 152 at a smaller distance from the barrier assembly 124, so that they can rotate freely relative to the barrier assembly 124 and the ball bearings 154, 156.

[0107] The primary turbine wheel 150 and the secondary turbine wheel 152 have substantially the same structure and are only arranged on a shaft 154 rotated 180 degrees. Therefore, for simplicity, the features of one of the two turbine wheels 150, 152 described below are correspondingly applicable to the other. The primary turbine wheel 150 is configured to be substantially flat on the side facing the barrier assembly 124 and has only an opening with an inner circumferential geometry to receive the shaft 120. On the side away from the barrier assembly 124, the secondary turbine wheel 152 has an air inlet opening 166 arranged in the center, which is surrounded by an annular side surface 168 and is configured to protrude relative to the annular side surface 168. The secondary turbine wheel 152 is configured with a plurality of internal turbine blades 170, which are arranged to generate an air flow when the secondary turbine wheel 152 moves or to move the secondary turbine wheel 152 based on the air flow. The turbine blades 170 are arranged such that when the secondary turbine impeller 152 rotates about the axis A in a first rotational direction, an air flow is directed outwardly from the inlet opening 166 to radial openings 172 arranged on the outer circumference of the secondary turbine impeller 152. This air flow corresponds to the secondary suction air flow. The first rotational direction corresponds to the rotational direction of the adapter device 110 during operation. If the secondary turbine impeller 152 is rotated in a second direction opposite to the first rotational direction, the air flow is directed outwardly from the radial openings 172 through the secondary turbine impeller 152 to the inlet opening 166. As described above, the primary turbine impeller 150 is constructed similarly to the secondary turbine impeller 152, in particular, the shape of the turbine blades can also be changed or configured in an adapted manner thereby. This is because the primary turbine wheel 150 is primarily intended to be driven by a suction air flow (the so-called primary suction air flow) directed from a radial opening 172 of the primary turbine wheel 150 to an outlet opening 174 configured similarly to the inlet opening 166, while the secondary turbine wheel 152 (as described above) is configured to generate an air flow (the so-called secondary suction air flow) based on its rotation in a first rotational direction, which is directed from the inlet opening 166 to the radial opening 172.

[0108] The inlet opening 166 is adapted to receive the second shaft nut 164 so that the second shaft nut 164 contacts the secondary turbine wheel 152 at the inner surface and fixes it axially on the shaft 154. Correspondingly, the outlet opening 174 is configured to receive the first shaft nut 162 so that the first shaft nut 162 contacts the primary turbine wheel 150 at the inner surface and fixes it axially on the shaft 154. The internal arrangement of the respective shaft nuts 162, 164 has the advantage of minimizing interference with the airflow.

[0109] The barrier assembly 124 is disc-shaped, substantially axisymmetric with respect to the axis A, and symmetrical with respect to the center plane of the barrier assembly 124 orthogonal to the axis A. Ribs 176 are arranged on both sides in the direction of the axis A, which are used to reinforce the barrier assembly 124. In addition to the opening 160, no channel is arranged in the direction of the axis A, so that no fluid can pass through the barrier assembly 124. At least one sealing assembly can be arranged at the opening 160 relative to the ball bearings 156, 158, so that no fluid can pass between the ball bearings 156, 158 and the barrier assembly 124. Similarly, a sealing assembly can also be arranged in the area between the ball bearings 156, 158 and the shaft 154. The ball bearings 156, 158 are also configured to be fluid-tight. An annular center web 180 is arranged on the circumferential surface 178 of the barrier assembly 124. On one side of the central web 180, in the direction along the axis A to the first turbine assembly 112, a first radial connection surface 182 is arranged to contact the first housing part 126 and fix it to the barrier assembly 124. On the other side of the central web 180, in the opposite direction along the axis A, i.e. in the direction of the second turbine assembly 118, a second radial connection surface 184 is arranged to contact the second housing part 128 and fix it to the barrier assembly 124. A plurality of corresponding fastening bolts 186 are arranged on the connection surfaces 182, 184 for fastening, which together with the housing parts 126, 128 form corresponding bayonet locks. Another fastening assembly (e.g. a threaded screw connection) can be provided instead of the bayonet lock. In addition or alternatively, clips can be provided, which can be snapped into each other for re-tightening and releasing. The advantage of the bayonet lock is that it is simple to operate. A connecting fork for the bayonet lock is provided on the first connection surface 182. A respective sealing assembly may be provided at the circumferential surface 178 (eg, at the connection surfaces 182 , 184 ) to provide a fluid-tight connection between the respective housing portion 126 , 128 and the barrier assembly 124 .

[0110] The first housing part 126 has an annular portion 188, which is configured to be hollow inside and, in particular, surrounds the primary turbine impeller 150 and the barrier assembly 124, at least when attached to the first connection surface 182. The annular portion 188 has a plurality of air passage openings 190, which are used to provide the primary turbine impeller 150 with air contact with the surrounding environment. Therefore, under an operating condition, the primary suction air flow can pass through the air passage openings 190 to reach the primary turbine impeller 150. An inner circumferential surface 192 is also configured on the annular portion 188, which is suitable for contacting the first connection surface 182. For this purpose, a counterpart of the bayonet lock is configured on the inner circumferential surface 192 in the form of a plurality of groove components, which are configured to receive corresponding connection forks of the barrier assembly 124.

[0111] In addition, the primary connection interface 130 is formed on the first housing portion 126 in the form of a tubular portion, which is configured to be connected to a suction device, such as a hose or a nozzle of a dry vacuum cleaner. To this end, the hose or the nozzle can surround the tubular portion or be pushed into the tubular portion. The tubular portion is hollow inside and extends into the annular portion 188. In addition, a first connecting lug 183 and a second connecting lug 185 are formed on the first housing portion 126. These lugs are arranged on opposite sides of the first housing portion 126 relative to the axis A in a radial direction. These lugs are used to interact with a connection assembly optionally arranged on the suction device to fixedly but detachably connect the suction device to the primary connection interface 130.

[0112] An outwardly open air passage opening 195 is arranged between the annular portion 188 and the tubular portion 130, wherein the first housing portion 126 is arranged to be coupled to an actuatable valve assembly 194. In the present example, the valve assembly 194 is arranged as a two-piece annular throttle valve, wherein the two parts of the throttle valve can be detachably clamped together, and the throttle valve can be rotated about the axis A relative to the first housing portion 126. The throttle valve also has an air passage opening, which can coincide with the air passage opening of the first housing portion 126 or close it depending on the rotational position. This allows the proportion of the primary suction air flow passing through the primary turbine impeller 150 to be adjusted.

[0113] The second housing part 128 also has an annular portion 196 with an air passage opening to allow the air delivered by the secondary turbine wheel 152 (secondary suction air flow) to escape into the surrounding environment. For example, with respect to the fastening assembly, this annular portion 196 is structurally similar to the annular portion 188 of the first housing part 126, so that reference can be made to its other features (e.g., bayonet lock).

[0114] The second housing portion 128 also includes a secondary connection interface 136 configured as an annular extension. The secondary connection interface 136 has a portion of a bayonet lock, i.e., a plurality of groove assemblies. The secondary connection interface 136, in particular the annular extension, is configured to be connected to a module such as a collection container. To this end, a sealing assembly can be provided between the secondary connection interface 136 and the module to provide a fluid-tight connection. Alternatively or additionally, the secondary connection interface 136 can also be configured on a tubular air inlet region 198 formed on the second housing portion 128 and present in this example. The annular extension is supported by a plurality of ribs relative to the tubular air inlet region 198.

[0115] Figure 41 is a schematic cross-sectional view of another embodiment of an adapter device 110 according to the present invention in an assembled or connected state. Therefore, the first housing part 126 is attached to the barrier assembly 124 by a bayonet lock. To this end, the inner circumferential surface 192 contacts the first connection surface 182 and forms a substantially fluid-tight connection. The first housing part 126 surrounds the primary turbine impeller 150, but is spaced apart from it in the radial direction. The air channel opening 190 provided on the annular portion 188 allows the primary suction air flow to enter and pass through the adapter device 110 or the first turbine assembly 116. The air channel opening 195 is closed by the valve assembly 194 so that the primary suction air flow enters only through the air channel opening 190. This allows the primary suction air flow to fully act on the first turbine assembly 112 and drive the primary turbine impeller 150. For simplicity, the primary connection interface 130 is not connected to any suction device. However, the arrows indicate the flow of the primary suction air flow and the generated secondary suction air flow.

[0116] The second housing part 128 is attached to the barrier assembly 124 by means of an associated bayonet lock. To this end, the inner circumferential surface of the annular part 196 is in contact with the second connection surface 184 of the barrier assembly 124. The second housing part 128 surrounds the secondary turbine wheel 152, but is spaced apart from it in the radial direction. An air passage opening provided on the annular part 196 (not visible in the cross-sectional view due to the offset) allows the secondary suction air flow to enter the adapter device 110 or the second housing part 128 via the air inlet area 198 and pass through the second turbine assembly 118. For the sake of simplicity, no module is arranged at the secondary connection interface 130. However, the arrows indicate the flow of the secondary suction air flow.

[0117] The primary suction air flow thus passes through the first turbine assembly 116 and acts on the primary turbine impeller 150 by exerting a driving force in the circumferential direction on the individual turbine blades 173 of the primary turbine impeller 150. The first turbine assembly 116 is thus driven by means of the primary suction air flow. Since the primary turbine impeller 150 is coupled to the transmission assembly 120, which includes the shaft 154, in a rotationally fixed manner in the assembled state, the rotational drive of the primary turbine impeller 150 leads to a rotational drive of the shaft 154 and thus to a rotational drive of the secondary turbine impeller 152, which is also coupled to the shaft 154 in a rotationally fixed manner in the assembled state. The rotation of the secondary turbine impeller 152 acts on the air present in the second turbine assembly 118, pushes the air out of the adapter device 110 in the radial direction through the air passage opening, and draws the air in through the air inlet region 198. In this way, a secondary suction air flow is generated. The secondary suction air flow can be used to draw in a suction medium.

[0118] Obviously, the two suction air flows are two different and structurally separated suction air flows. In this case, the barrier assembly 124, among other functions, ensures that the suction air flows are spatially separated from each other. During operation, the rotation of the primary turbine wheel 150 also ensures that any residues of the suction medium (e.g., moisture or liquid) are exhausted to the outside and do not enter the primary suction air flow.

[0119] It can also be seen that the shaft 154 and the turbine wheels 150 , 152 rotate about a common axis A in an operating state.

[0120] Various structural measures can be provided to prevent air, dirt, moisture and / or liquids (in particular water) etc. from entering the inflowing primary suction air flow from the outflowing secondary suction air flow in the region of the annular sections 188, 196. For example, the air passage opening 190 and the air passage opening of the second housing part 128 can be arranged offset to one another in the circumferential direction, an additional structural barrier can be provided between them, or the air passage opening 190 can be provided only on one side of the adapter device, while the air passage opening of the second housing part 128 is arranged on the opposite side.

[0121] In order to be able to drain the liquid, a third connection interface similar to the first embodiment may be provided instead of the air passage opening of the second housing part 128. For example, it may be configured as a connector for a hose.

[0122] For example, a region of the primary connection interface 130 (eg, its peripheral surface) may be configured to be coupled to a handle assembly. Alternatively, a handle assembly may be formed thereon. For example, the handle assembly includes a handle with which an operator can operate the adapter device 110.

[0123] Figure 5 A cleaning assembly 300 according to the present invention is shown, which comprises Figure 3 and Figure 4 The adapter device 110 and the collection container assembly 200, as well as the first handle assembly 202 and the second handle assembly 204.

[0124] The collecting container assembly 200 has a collecting container 201 of substantially tubular configuration, the inner diameter of which is substantially constant, but other geometric shapes are also possible. The collecting container 201 is hollow and extends along a collecting container axis S, which in the coupled state shown coincides with the axis A of the adapter device 110. Furthermore, the collecting container is configured as a rotating body. The ratio of the wall thickness of the collecting container 201 to its radius is at least 1:10, preferably at least 1:20. The collecting container assembly 200 is coupled to the adapter device 110 by means of a secondary connection interface 136 of the adapter device 110, in this case a bayonet lock. For this purpose, four bolts are formed at the first end 206 of the collecting container 201, which extend radially outwards from a lateral surface 208 of the adapter device 110 and engage with openings of the bayonet lock of the adapter device 110. In other words, a portion of a bayonet lock complementary to the bayonet lock on the adapter device 110 is formed on the collecting container 201. The collection container assembly 200 and the adapter device 110 can be separated from each other by rotating relative to each other in a first rotational direction. In addition, the collection container assembly 200 and the adapter device 110 can be fixedly coupled to each other by rotating in a second rotational direction opposite to the first rotational direction. The secondary connection interface 136 can also have another type of coupling (e.g., a threaded screw connection or fastening by means of screws, etc.) instead of a bayonet lock.

[0125] The secondary connection interface 136 enables a rigid coupling of the adapter device 110 and the collection container assembly 200, thereby making them impermeable to fluids from the surrounding environment. Thus, the movements of the adapter device 110 and the collection container assembly 200 are coupled to each other, and a movement or tilting of the collection container assembly 200 also causes a corresponding movement or tilting of the adapter device 110, and vice versa.

[0126] The lateral surface 208 also has a plurality of annular recesses 209. These recesses 209 are configured to reduce the outer diameter of the collecting container 201. The recesses 209 extend in the direction of the collecting container axis S with a predetermined width, wherein the ratio of the width to the distance from the adjacent recesses 209 is at least 1:3, preferably at least 1:4. In addition, a first handle assembly 202 and a second handle assembly 204 are formed on the lateral surface 208. The first handle assembly 202 has two coupling rings 210 and a two-piece handle component 212. The coupling ring 210 completely surrounds the lateral surface 208 or engages in a corresponding one of the recesses in the recesses 209. The two-piece handle component 212 is similar to a parallelogram and has a grip area (Griffbereich) 214 configured to be gripped by an operator. The grip area 214 represents the upper side of the parallelogram, which is aligned substantially parallel to the collecting container axis S.

[0127] The second handle assembly 204 also has a coupling ring 216 which completely surrounds the lateral surface 208. Furthermore, the second handle assembly 204 has an L-shaped holding bracket 218 with a handle area 220, the longitudinal axis of which is aligned substantially transversely to the collection container axis S. The holding bracket 218 is coupled to the coupling ring 216 by means of a lockable pivot joint 222, wherein the pivot joint 222 can be opened by slightly loosening a screw in order to pivot the holding bracket 218 relative to the coupling ring 216 about a pivot axis A1 which is aligned vertically relative to the collection container axis S.

[0128] A coupling ring 210 can be arranged on each recess 209 as required. Instead of recesses, the lateral surface 208 can also be configured with a constant outer diameter, in which case, preferably, the coupling ring 210 can be attached to the lateral surface 208 by means of a clamping action. This additionally increases the variability of the operator, who will not be limited to making couplings in recesses 209 that are equidistantly spaced from one another.

[0129] The collection container assembly 200 also includes a tool connection module 224 having a tool connection interface 226. The tool connection interface 226 is configured to be connected to a cleaning tool. The tool connection interface 226 includes: a tubular member 228 arranged concentrically with the collection container axis S; and two connection lugs 229 arranged on both sides of the tubular member 228. The tool connection module 224 also includes a connection flange 230, which is configured in an annular shape and surrounds the second end 232 of the collection container 201, and the second end 232 is configured on the other side of the first end 206 of the collection container 201. In addition, the connection flange 230 includes a bayonet lock or a bayonet lock component, which is suitable for interacting with an associated bayonet lock component configured on the collection container assembly 200 to connect the tool connection module 224 to the collection container assembly 200.

[0130] The collection container assembly 200 is transparent. This enables an operator to see the interior of the collection container assembly 200 and any suction medium collected therein. Alternatively, a viewing window may also be provided so that only a portion of the collection container assembly 200 is transparent. For example, the collection container assembly 200 or the viewing window may comprise a transparent material, in particular a transparent polymer, such as acrylic glass, polycarbonate or polystyrene. In addition or as an alternative to a transparent design, an opaque material, in particular an opaque polymer, may also be provided.

[0131] A standpipe 234 is arranged in the collection container assembly 200, but due to the simplification of the description, it is not shown in more detail, and it will be described in more detail below. The standpipe 234 extends from the second end 232 along the collection container axis S in the direction of the first end 206. However, along the collection container axis S, the standpipe 234 is arranged at a certain distance from the first end 206. In other words, the length of the standpipe 234 is approximately 60% to 90%, preferably 85% of the length of the collection container assembly 200. The standpipe 234 is detachably connected to the tool connection module 224. To this end, an external thread is formed on the standpipe 234, and the external thread is screwed together with the internal thread formed on the tool connection module 224.

[0132] The standpipe 234 is used to guide or draw the secondary suction air flow together with the suction medium into the collecting container 201. Since the standpipe 234 is open at the end facing the first end 206, the secondary suction air flow can escape into the collecting container 201 together with the suction medium. This design of the standpipe 234 also helps to separate the suction medium from the secondary suction air flow and collect it in the collecting container 201. Gravity pulls the suction medium toward the second end 232 of the collecting container 201 so that it collects there, while the light suction air flow can flow to the first end 206 and thus into the adapter device 110.

[0133] In order to remove the suction medium from the collection container 201 or to empty the collection container, the adapter device 110 can be separated from the collection container assembly 200. To this end, the snap lock (secondary connection interface) can be opened. Alternatively, the tool connection module 224 can also be separated from the collection container 201. In addition, the collection container 201 can include a drain, which can be opened or closed as required.

[0134] Figure 6 2 is an exploded view of the collection container assembly 200. A sealing assembly 236 is disposed at the first end 206 of the collection container 201. The sealing assembly 236 is configured to couple the collection container 201 to the adapter device 110 in a fluid-tight manner. In this example, the sealing assembly 236 is configured as an O-ring.

[0135] The collection container assembly 200 also includes a splash-proof assembly 238, which is arranged at one end of the standpipe 234 oriented toward the first end 206 and can be connected to the standpipe 234. The splash-proof assembly 238 is configured to form a barrier to the suction medium sucked into the standpipe 234 by the secondary suction air flow, so that the suction medium does not flow out of the standpipe 234 in the direction of the first end 206 and the collection container axis S, but flows out in a radial direction. This is conducive to separating the suction medium from the secondary suction air flow and gathering it in the collection container 201. In other words, the suction medium can be prevented from leaving the standpipe 234 in the direction of the adapter device 110. The splash-proof assembly 238 has a tubular portion 240 and a disc portion 242. The tubular portion 240 is configured to be connected to the standpipe 234 by being pushed onto the standpipe 234. Other connection methods are also conceivable, for example, connection by mutually meshing threads. The disk-shaped portion 242 is configured to be closed in the direction of the collecting container axis S and prevent the suction medium from passing through. The tubular portion 240 comprises radially arranged passage openings 244 which allow the suction medium or the secondary suction air flow to pass through or out of the standpipe 234 in the radial direction.

[0136] Alternatively, an elastic suction hose may be used instead of the standpipe 234. In addition, the suction hose may also be guided to the outside of the collecting container assembly 200 and may enter the collecting container 201 below the first end 206 through a connector. In this way, the secondary suction air flow may also be introduced into the collecting container 201 below the first end 206, preferably at a certain distance from the first end 206.

[0137] A seal assembly 246 in the form of an O-ring is disposed between the riser 234 and the tool connection module 224 .

[0138] The electrical contacts 248 forming the electrical contact assembly 249 are arranged on two connecting lugs 229 of the tool connection module 224. When the cleaning tool is connected to the tool connection module 224, the electrical contacts are used to establish electrical contact with the cleaning tool. In this example, the electrical circuit 250 is also arranged on the collection container 201. The electrical circuit can be arranged as an insulated conductor on the inside or outside of the collection container 201. Alternatively, the electrical circuit 250 can be configured to be embedded in the material of the collection container 201 at least in sections. In addition, electrical contacts (not shown here) can also be arranged at the second end 232, which are configured to establish electrical contact between the electrical circuit 250 and the tool connection module 224 and its electrical contacts 248. Similarly, electrical contacts (not shown here) can also be arranged at the first end 206, which are configured to establish electrical contact between the adapter device 110 and the electrical circuit 250. In this example, each electrical circuit 250 is directly connected to each electrical contact 248.

[0139] Figure 73 is a partial exploded view of the cleaning assembly 300. The collection container assembly 200 is shown in an assembled state. Therefore, the tool connection module 224 is fixedly connected to the collection container 201 by means of a bayonet lock. In addition, a standpipe 234 with a splash guard assembly 238 is arranged inside the collection container 201 and is fixedly connected to the tool connection module 224. No cleaning tool is connected to the tool connection module 224. Two handle parts (Griffteil) 212, 214 are separated from the collection container 201, wherein the two handle parts can be connected to the corresponding recesses 209 of the lateral surface 208 of the collection container 201.

[0140] In accordance with Figure 7 In the partially exploded view of , the collecting container assembly 200 is separated from the adapter device 110 and is spaced apart from each other along the axis A or the collecting container axis S. In addition, a suction protection device 252 is arranged between the adapter device 110 and the collecting container assembly 200. The suction protection device 252 is arranged to be connected to the adapter device 110. More precisely, the suction protection device 252 can be connected to the tubular air inlet area 198. In each case, the associated bayonet locking components are configured for this purpose, but the connection can also be made by a threaded connection or the like. Alternatively, the suction protection device 252 can be configured to be integral with the adapter device 110. According to the invention, in the connected state and during operation of the adapter device 110, a secondary suction air flow is extracted from the collecting box assembly 200, starting from the second turbine assembly 118, via the tubular air inlet area 198 and therefore via the suction protection device 252. The suction protection device 252 (not shown in detail) comprises an internal air guiding assembly for supplying air from the collecting container assembly 200 to the adapter device 110. The external shape of the suction protection device 252 is configured so that when coupled to the tubular air inlet area 198, in particular to the radial inner surface of the air inlet area 198, it is substantially fluid-tight with the latter, so that the secondary suction air flow can only flow via the internal air guiding assembly of the suction protection device 252. When coupled to the adapter device 110, the suction protection device 252 extends along the axis A. Furthermore, when the adapter device 110 is coupled to the collecting container assembly 200, the suction protection device 252 further extends along the collecting container axis S. Furthermore, the suction protection device 252 is arranged at a distance from the inner surface of the collecting container 201.

[0141] The suction protection device 252 (not shown in more detail) comprises a closing body which in its closed position closes the air guide assembly so that at least no liquid, preferably neither liquid nor air, can pass from the collecting container assembly 200 to the adapter device 110, and in its open position releases the air guide assembly to suck air from the collecting container assembly 200. In addition, the suction protection device 252 comprises a force actuator for generating an actuation force, by which the closing body can be pushed into the closed position and / or the open position. Advantageously, the suction protection device 252 is controllable so that the open position and the closed position can be set according to a control signal. In particular, when a conventional suction operation is performed by means of the adapter device 110, the closing body is in the open position. In particular, when the level of the suction medium in the collecting container 201 exceeds a predetermined level and / or the suction operation of the adapter device 110 is terminated, the closing body should be in the closed position so that the suction medium cannot be transferred from the collecting container assembly 200 to the adapter device 110 even in the case of pivoting, tilting, transportation, storage or the like. Preferably, the actuating force of the force actuator comprises a magnetic force.

[0142] The suction protection device 252 is an optional component of the cleaning component 300. Therefore, the cleaning component 300 may not be provided with the suction protection device 252.

[0143] Figure 8 yes Figure 5 25 is a diagram of a cleaning assembly 300 coupled to an exemplary suction device 254. The suction device 254 is a conventional dry vacuum cleaner that can be operated using household electricity, but any other type of suction device can also be provided. The suction device 254 includes a main body 256 that can be displaced relative to the floor surface by a rolling action of two wheels 258 and a front wheel (not shown) arranged at its rear lower end. All wheels 258 protrude at least partially from the underside of the main body 256 and separate the main body 256 from the ground. The main body 256 includes a carrying handle 260 arranged at its rear upper end and configured in an arc.

[0144] An elastic suction hose 262 is coupled to the body 256. The suction hose 262 includes a handle portion 264 that can be grasped by an operator, and includes a suction nozzle 266. The handle portion 264 and the suction nozzle 266 are configured to be substantially rigid. The suction nozzle 266 is coupled to the primary connection interface 130 of the adapter device 110 by a clamping action. To this end, the suction nozzle 266 is configured to be tubular, wherein the outer diameter of the suction nozzle 266 substantially corresponds to the inner diameter of the tubular portion of the primary connection interface 130, or is configured to be slightly smaller than the inner diameter of the tubular portion of the primary connection interface 130, so as to be at least partially inserted into the tubular portion of the primary connection interface 130.

[0145] The suction device 254 is configured to generate negative pressure during operation. To this end, the suction device 254 has a turbine assembly, not shown in detail, which is configured to generate negative pressure at the suction hose 262 and discharge the extracted air into the surroundings of the body 256. The negative pressure generated at the suction hose 262 causes the primary suction air flow to eventually flow from the surroundings of the adapter device 110 through the air channel opening 190 into the first turbine assembly 116 to drive the primary turbine impeller 150. The suction air flow then further passes through the primary connection interface 130 and leaves the adapter device 110, thereby passing through the suction nozzle 266, the handle portion 264 and the suction hose 262 into the body 256 of the suction device 254, and then flows out of the turbine assembly into the surroundings of the suction device 254.

[0146] Thus, the cleaning assembly 300 can be driven by means of the suction device 254. During operation of the cleaning assembly 300, the body 256 can stand on the floor surface. The operator can freely move the cleaning assembly 300 and use it according to the cleaning requirements. Advantageously, the cleaning assembly 300 according to the invention makes it possible to drive the cleaning assembly 300 using the suction device 254 configured as a dry vacuum cleaner, thereby ensuring that no suction medium, in particular no liquid or moist air, can escape from the cleaning assembly 300, in particular the secondary suction air flow, and enter the primary suction air flow and thus the suction device 254. In order to simplify the representation, the recess 209 is no longer shown.

[0147] Fig. 9 is an exemplary partial illustration of an adapter device 110 having various suction devices or handle components that can be coupled to the primary connection interface 130 and are spaced apart from and separated from the primary connection interface 130 according to an exploded view. Figure 8 The suction hose 262 known from FIG. 1 is shown with a handle part 264 and a suction nozzle 266. In addition, an alternative suction device 268 in the form of a handheld vacuum cleaner, as well as a third handle assembly 269 and a fourth handle assembly 271 are also shown.

[0148] The suction device 268 includes a body 270 that is generally cylindrical, and a handle assembly 272 that can be grasped by an operator is configured on the rear end of the body 270. The handle assembly 272 includes an upper handle component 274 that is adjacent to the body 270 and extends away from the body 270. In this example, the upper handle component 274 is configured as a rectangular parallelepiped shape, but it can also be round or configured in other ways. Preferably, the upper handle component 274 is configured to be ergonomic, so that the operator can grasp it comfortably. The arc-shaped lower handle component 276 extends below the upper handle component 274. The lower handle component 276 is configured to be integrated with the rear end of the upper handle component 274 at one end thereof and integrated with the body 270 at the other end thereof. The lower handle component 276 is substantially L-shaped and has a generally cubic shape, but it can also be round or other shapes. Preferably, the lower handle component 276 is configured to be ergonomic, so that the operator can grasp it comfortably.

[0149] The front end of the cylindrical body 270 is configured to be coupled to the primary connection interface 130 of the adapter device 110. To this end, a tubular portion, not shown in detail, is configured on the inside of the body 270, which is configured to be coupled to the tubular portion of the primary connection interface 130 in a manner similar to the suction nozzle 266 of the suction device 254. However, in addition, the body 270 also has an actuable connection assembly 275, which includes an actuable rocker arm 276, 278, which is configured to interact with the connection lugs 183, 185 of the first housing part 126 of the adapter device 110. When coupled, the rocker arm 276, 278 engages with an end behind the respective connection lug 183, 185, thereby preventing the suction device 368 from being separated from the adapter device 110. However, the operator can actuate the second ends of the rocker arms 276, 278 so that the respective rocker arms 276, 278 are no longer engaged behind the respective connecting lugs 183, 185, thereby releasing the suction device 268 to be separated from the adapter device 110. The operation of such a rocker arm will be further described below, and the rocker arm can be configured in a manner described below.

[0150] The main body 270 further comprises laterally arranged air passage openings 280 which are arranged to discharge a primary suction air flow generated by the primary connection interface 130 and a suction turbine arranged in the suction device 268 into the surrounding environment.

[0151] The suction device 268 is configured to be detachably connected to a battery that provides electrical energy to drive the suction turbine. To this end, a socket can be provided on the suction device 268 to connect the battery to the suction device 268. A switch 282 is arranged on the upper side of the suction device 268 so that the suction turbine is powered on or off according to the position of the switch 282.

[0152] The suction device 268 is shown as an example and is intended to illustrate that the adapter device 110 or the cleaning assembly 300 can also be connected and operated by a battery-operated compact suction device.

[0153] The third handle assembly 269 and the fourth handle assembly 271 are also configured to be coupled to the primary connection interface 130. To this end, they each have a coupling ring 284, which is configured to be coupled to the outer peripheral surface of the tubular portion of the primary connection interface 130. In addition, the operator can grip the handle assemblies 269, 271. To this end, the third handle assembly 269 has a gripping body 286, which includes a gripping portion configured to be similar to a parallelogram. The coupling ring 284 is configured to be integral with the gripping body 286 at its lateral surface. In addition, the third handle assembly 269 includes a rocker arm 288, which is configured to interact with the first connection lug 183 or the second connection lug 185 of the first housing portion 126 of the adapter device 110. On the one hand, the rocker arm 288 makes it possible to fixedly but releasably couple the third handle assembly 269 to the adapter device 110. At the same time, in the coupled state, the third handle assembly 269 is prevented from rotating about the axis A because the rocker arm 288 is engaged behind one of the connecting lugs 183, 185 in a rotationally blocking manner.

[0154] When the term "rocker arm" is used, it may refer to a connection mechanism that is configured to couple and / or decouple a handle assembly from an adapter device and / or a collection container assembly when actuated.

[0155] The fourth handle assembly 271 has a grip body 290, which is arranged below the coupling ring 284 and is configured to be similar to a pistol grip and at least partially grasped by the operator's hand. The fourth handle assembly 271 also has a rocker arm 292, which operates in a similar manner to the aforementioned rocker arm. The coupling ring 284 is configured to be integral with the grip body 290.

[0156] Fig.10a2 is an exploded view of the third handle assembly 269. The third handle assembly 269 has a first housing portion 294 and a second housing portion 296. The first housing portion 294 has one half of the gripping body 286 and one half of the coupling ring 284. The second housing portion 296 has the other half of the gripping body 286 and the other half of the coupling ring 284. The second housing portion 296 has four openings 298 on its inner side, into which corresponding threaded inserts 302 can be inserted. In the inserted state, the threaded inserts 302 are fixedly coupled to the second housing portion 296. The first housing portion 294 includes four through holes 304, which are configured to receive corresponding screws 306, which can be screwed onto the corresponding threaded inserts 302, so as to fixedly couple the first housing portion 294 to the second housing portion 296.

[0157] At least the second housing part 296 has a receiving bolt 308, which is configured to receive the rocker arm 288 and support the rocker arm in an articulated manner. To this end, the rocker arm 288 has a through hole 310 in its central region, which is configured to receive the receiving bolt 308. In addition, the rocker arm 288 has a first leg 312 and a second leg 314. The two legs 312, 314 are configured to contact the second housing part at least in sections when the second housing part 296 is in an attached state. The two legs 312, 314 are slightly bent. This allows the operator to actuate one end of the first leg 312 protruding from the second housing part 296 in a state where the first leg 312 is attached to the second housing part 296, so that at least the second leg 314 is elastically deformed and tensioned. This causes the lug 311 configured between the two legs 312, 314 and in the through hole 310 region to shift around the longitudinal axis K of the positioning pin 308. Then, if the third handle assembly 269 is coupled to the adapter device 110, the lug 311 is no longer engaged behind the first connection lug 183 or the second connection lug 185 of the first housing portion 126 of the adapter device 110, so that the third handle assembly 269 can be separated from the adapter device 110. This mechanism enables the third handle assembly 269 to be fixedly but releasably coupled to the primary connection interface 130 or the first housing portion 126 of the adapter device 110.

[0158] To assemble the third handle assembly 296, the threaded insert 302 and the rocker arm 288 are first inserted into the second housing portion 296. Subsequently, the first housing portion 294 is assembled with the second housing portion 296 so that the axis of the through hole 304 is aligned with the axis of the opening 298. Then, the screw 306 is passed through the through hole 304 and screwed onto the threaded insert 302.

[0159] Fig.10bis an exploded view of the fourth handle assembly 271. The fourth handle assembly 271 has a first housing portion 316 and a second housing portion 318. The first housing portion 316 has one half of the gripping body 290 and one half of the coupling ring 284. The second housing portion 318 has the other half of the gripping body 290 and the other half of the coupling ring 284. Three receiving openings 320 are configured on the inner side of the second housing portion 318, and the receiving openings are configured to receive corresponding threaded inserts 322 as described above. The first housing portion 316 has three through holes 324, which are configured to receive corresponding screws 326 therein.

[0160] The two housing parts 316, 318 have respective receiving openings 328, which are configured to receive respective ends of guide pins 330 formed on the rocker arm 292. In the present example, only the receiving opening 328 of the second housing part 318 can be identified. The two housing parts 316, 318 have respective openings 332. If the rocker arm 292 is inserted into the receiving opening 328, it is pivotably mounted about the axis K of the guide pin 330. In addition, one end of the first leg 334 then protrudes through the opening 332 and can be actuated by an operator. A lug 338 is configured at the end of the second leg 336 of the rocker arm 292. As described above, the lug 338 is arranged to engage behind one of the connecting lugs 183, 185, thereby fixedly but releasably coupling the fourth handle assembly 271 to the adapter device 110.

[0161] A lug 340 is also provided on the first leg 334, which lug is arranged to support a spring member 342, so that when the fourth handle assembly 271 is mounted on the first leg 334, the spring member 342 is pushed in a first rotational direction about the axis K. If the fourth handle assembly 271 is attached to the adapter device 110, the lug 338 is then pushed behind one of the connecting lugs 183, 185. In order to release the connection between the lug 338 and the corresponding connecting lug 183, 185, the operator grasps the end of the first leg 334 protruding from the two housing parts 316, 318 and pushes it in a second rotational direction opposite to the first rotational direction about the axis K. In the process, the operator has to overcome the actuation force of the spring member 342.

[0162] To assemble the fourth handle assembly 271, the threaded insert 322 is first inserted into the receiving opening 320 of the second housing portion 318. In addition, the spring member 342 is inserted into the receiving opening 344 formed on at least one of the housing portions 316, 318, wherein the spring member 342 is engaged with the lug 340 and inserted into the second housing portion 318 together with the rocker arm 292. Subsequently, the first housing portion 316 is assembled with the second housing portion 318 so that the axis of the through hole 324 is aligned with the axis of the opening 328. Then, the screw 326 is passed through the through hole 324 and screwed onto the threaded insert 322.

[0163] Fig.11 3 is an illustration of a cleaning assembly 300 having exemplary cleaning tools 346, 348, 350. Each cleaning tool is configured to be attached to the tool connection interface 226. The cleaning assembly 300 is shown in an assembled state and without a suction device coupled thereto.

[0164] The first cleaning tool 346 includes a floor unit 352, wherein a first brush 354 rotating around a first brush axis B1 and a second brush 356 rotating around a second brush axis B2 are arranged on the floor unit. The two brush axes B1 and B2 are arranged at a certain distance from each other. The brushes 354 and 356 are configured to contact the floor surface to be cleaned during operation. The floor unit 352 also includes an arc suction rod assembly 356, wherein a suction lip 359 is arranged on the suction rod assembly 356, and the suction lip 359 is configured to contact the floor surface and suck away and collect the suction medium, especially liquid, on the floor surface. The first cleaning tool 346 also includes a connection module 358 configured to be connected to the tool connection module 224. To this end, the connection module 358 includes a tubular portion 360 configured to be connected to the tubular member 228. More specifically, the tubular portion 360 is slid onto the tubular member 228. The tubular portion 360 also includes a second end connected to the suction hose 362. The suction hose 362 connects the tubular portion 360 to the suction rod assembly 356, so that during operation, the secondary suction air flow can flow from the suction rod assembly 356 through the suction hose 362 and the tubular portion into the pipe 228 of the tool connection interface 226 to suck the suction medium. To this end, preferably, a suction opening is configured on the suction rod assembly 356 near the floor surface, and the secondary suction air flow with the suction medium can enter the suction hose 362 through the suction opening.

[0165] The connection module 358 is coupled to the floor unit 352 via a joint assembly 364. The joint assembly 364 has a first pivot axis SA1 and a second pivot axis SA2 that are vertically aligned and spaced apart from each other. The joint assembly 364 enables the connection module 358 and, for example, the container assembly 200 coupled thereto to be pivotally arranged relative to the floor unit 352. This enables easy manipulation of the cleaning assembly 300.

[0166] The second cleaning tool 348 also includes a connection module 358 as described above, wherein a scraper head 366 is disposed on the tubular portion 360 rather than on a suction hose integrally configured with the tubular portion 360 or the connection module 358. The scraper head 366 is configured to be similar to a substantially equilateral triangle having a relatively small thickness, wherein the lower side of the triangle forms a suction lip 368 having a suction opening 370. The scraper head 366 is hollow inside, or is configured with at least one relatively large or relatively small airflow channel, which leads to the suction opening 370, so that the secondary suction air flow can enter the suction opening from the suction lip 368 and pass through the scraper head 366 to reach the tubular portion 360. The suction lip 368 can be formed by a rubber-like material. The suction lip 368 is configured to at least partially contact the floor surface during operation so that the suction medium is sent into the suction opening 370.

[0167] The third cleaning tool 350 has a floor unit 372, in which a first cleaning roller 374 and a second cleaning roller 376 are arranged. The first cleaning roller 374 has a first roller axis W1, around which the first cleaning roller can be driven to rotate. The second cleaning roller 346 has a second roller axis W2, around which the second cleaning roller can be driven to rotate. The two roller axes W1, W2 are arranged in parallel and keep a certain distance from each other. If the third cleaning tool 350 is placed on the floor surface, the roller axes W1, W2 are aligned substantially parallel to the floor surface. The cleaning rollers 374, 376 may include brushes and / or blades. The cleaning rollers 374, 376 contact the floor surface during operation. The third cleaning tool 350 also includes a connection module 358 as described above. Here, the connection module 358 includes a tubular portion configured to be connected to the tubular member 228. More specifically, the tubular portion 360 is slid onto the tubular member 228. The connection module 358 is further connected to the floor unit 372 via a pivot joint 378. The pivot joint 378 has a pivot axis SA3 that is parallel to and spaced apart from the roller axes W1, W2. The pivot joint 378 enables the connection module 358 to pivot relative to the floor unit 372 around the pivot axis SA3. A housing 380 is formed on the connection module 358 around the tubular portion 360. The tubular portion 360 is connected to a suction hose 382, ​​which in turn connects the connection module 358 next to the pivot joint 378 to the floor unit 372. The suction hose 382 is configured to discharge a secondary suction air flow from the floor unit 372 and supply it to the tubular portion 360. A motor drive is configured in the floor unit 372, and the motor drive is configured to drive the two cleaning rollers 374, 376 to rotate around the roller axes W1, W2. To this end, the motor drive is coupled to the cleaning rollers 374, 376 via a belt assembly, which in this example is formed outside the housing of the floor unit 350. Of course, the belt assembly may also be formed inside the housing. In addition, other mechanical couplings may be provided to replace the belt assembly.

[0168] Fig.12a and Figure 12b358 is a detailed illustration of the connection module 358 of the first cleaning tool 346, which, among other functions, is used to illustrate the mechanism by which the connection module 358 can be connected to the tool connection interface 226. As described above, the connection module 358 has a tubular portion 360. In addition, the connection module 358 has a first receiving opening 384 and a second receiving opening 386. The two receiving openings 384, 386 are arranged on opposite sides of the tubular portion 360, and a cubic recess is formed on the connection module 358. The connection module 358 also includes a locking bracket 388, which is configured as a separate component of the connection module 358, but is connected to the connection module 358. The locking bracket 388 has a corresponding hook 390 at its respective end, which protrudes into the receiving openings 384, 386 when the locking bracket 388 is not activated. Inactive means that the locking bracket is biased in a first direction R1 due to a spring assembly / spring element (not shown in detail), and the hook 390 thereby extends into the receiving openings 384, 386, but can still overcome the spring force of the spring assembly and be displaced relative to the remaining connection module 358 in the opposite direction R1. To this end, the operator presses the locking bracket 388 in the direction opposite to R1 and displaces the locking bracket 388 in the direction opposite to R1. Such displacement causes the hook 390 to come out of the receiving openings 384, 386 in the direction opposite to R1, thereby releasing the hook. The two receiving openings 384, 386 are configured to receive corresponding connection lugs 229 configured on the tool connection interface 226, wherein in the coupled state, the hook 390 engages through the corresponding through hole 410 of the corresponding connection lug 229. In this way, the hook 390 produces a locking effect, which prevents the connection module 358 from being separated from the tool connection interface 226 without actuating the locking bracket 388.

[0169] The connection module 358 has an upper housing portion 392 and a lower housing portion 394, wherein a through hole 396 configured on the lower housing portion 394 receives screws (not shown) that are configured to be screwed into a screw-in area 398 configured on the upper housing portion 392 to fixedly couple the upper housing portion 392 and the lower housing portion 394 together. If the upper housing portion 392 is coupled to the lower housing portion 394, the locking bracket 388 overcomes the spring force of the spring element and is clamped between the two housing portions. Therefore, the locking bracket 388 cannot be removed from the remaining connection module 358 without separating the housing portions 392 and 394 from each other.

[0170] The tubular portion 360 has, on its inner surface, a guide protrusion 400 extending along the longitudinal axis LA1 of the tubular portion 360. The guide protrusion 400 is configured to engage with a guide groove configured on the outside of the tubular portion 228.

[0171] The first receiving opening 384 has a first electrical contact plate 402, and the second receiving opening 386 has a second electrical contact plate 404. The contact plates 402, 404 are intended to contact a corresponding one of the electrical contacts 248 in a state coupled to the tool connection interface 226 to establish electrical contact therewith. The electrical contact plate 402 is coupled to a corresponding electrical circuit 406. For example, the electrical circuit 406 is in turn coupled to at least one electric drive to provide power thereto. An electric drive may be provided to drive the cleaning roller 374 or brush to rotate.

[0172] The electrical contact plates 402 , 404 can be omitted in the connection module 358 of the second cleaning tool 348 , since the second cleaning tool 348 has no drivable tool in the present example.

[0173] The connection module 358 of the third cleaning tool 350 is basically configured on the side facing the tool connection interface 226 in the same manner as the first cleaning tool 346, but also has the above-mentioned housing 380. The housing 380 can form a locking bracket 388. Alternatively, the connection module 358 of the third cleaning tool 350 can have only a tubular portion 360 and a housing 380 on the side facing the tool connection interface 226, wherein when the tubular portion 360 is pushed onto the tubular member 228, the tubular portion 360 and the tubular member 228 achieve a clamping effect.

[0174] Fig.13 Detailed view of one embodiment of the tool connection module 224. The tool connection module 224 is coupled and fixedly connected to the collection container 201. The guide groove 408 is configured on the tubular member 228 and extends along the axis A on the outer surface of the tubular member 228. The guide groove 228 is configured to receive the guide protrusion 400.

[0175] The tool connection module 224 also has two connection lugs 229, which protrude from the rear side of the tool connection module 224 in the direction of the axis A. The tool connection module 224 is configured in the form of a plate and has corresponding through holes 410. The through holes 410 are used to receive the hooks 390 described above.

[0176] Furthermore, an electrical contact 248 is arranged at the through-opening 410. The electrical contact 248 is also arranged at least partially on the underside of the connecting lug 229. Furthermore, the electrical contact 248 has a corresponding receiving extension 412, onto which a corresponding plug assembly 414, in the present case in the form of a flat plug sleeve, is pushed. Each plug assembly 414 is electrically conductively connected to a corresponding one of the electrical lines 250. Each electrical line 250 is fixed to the rear of the tool connection module 224 in the region of the corresponding receiving extension 412 by means of a corresponding line holder 416. For this purpose, the line holder 416 has a corresponding clamping jaw, which clamps the corresponding line 250. Preferably, the electrical line 250 is intended to provide a voltage of 12 V, 24 V or 48 V.

[0177] The electrical circuit 250 and associated structural features are optional. On the other hand, additional electrical circuits may also be provided in order to establish electrical contact with the cleaning tool or supply current to the cleaning tool.

[0178] A power supply interface for establishing electrical contact with a power source may be configured on the collection container assembly 200 or on the adapter device 110. Then, preferably, the power supply interface is coupled to the electrical line 250. The power supply interface may include a holder for receiving a power source. The holder may be configured to receive a battery.

[0179] It is also possible to provide the cleaning component, in particular the adapter device, with the features described for the specific embodiment separately. The same applies to the features described for the cleaning component. These features can also be provided in the adapter device, and vice versa.
