Description

The invention relates to an arrangement for an aircraft, with a device for dispensing a fragrance and/or air humidifier having the features of the preamble of claim 1. The invention also relates to a method for fastening the device in an aircraft cabin.

Fragrance dispensers are known, which are arranged along an air flow path of an air conditioning system of an aircraft in order to introduce a fragrance into the aircraft cabin via the air flowing in. Such fragrance dispensers are permanently installed in the air conditioning system of the aircraft and thus form an integral part of the aircraft.

The pamphlet WO 2017/ 205 418 A1 discloses a fragrance delivery system for an aircraft that includes a fuselage defining a cabin interior and an environmental control system (ECS). The ECS includes an air source that conveys air between the air source and the cabin interior along an airflow path. Furthermore, the ECS comprises a mixing unit which is in communication with the air source and is arranged downstream of the air source in the air flow path. The ECS also includes a fragrance delivery unit disposed between the air source and the cabin interior along the airflow path, the fragrance delivery unit being configured to deliver a fragrance into the airflow path.

From the DE 10 2015 208 993 A1 is a partial segment of an aircraft, in particular a cabin segment of a VIP aircraft, known with an electric chimney, the electric chimney having a flame simulation unit, and the electric chimney being permanently connected or connectable to a structural element of the aircraft, and an electric chimney for a cabin segment of a VIP aircraft, the electric fireplace having fastening elements for fixed attachment to a structural element of the VIP aircraft.

From the US 2015 / 0 047 197 A1 discloses a device for attaching an apparatus to a panel having at least one fitting opening. The device includes a clamping member having a jaw shaped to be engageable with a first surface on the backside of the panel, the jaw being shaped to be able to pass through the mating aperture of the panel to fit through.

It is the object of the present invention to propose a device for dispensing a fragrance and/or air humidifying agent, which is characterized by simple and quick installation in an aircraft cabin. Furthermore, it is the task to propose a corresponding method.

This object is achieved by an arrangement with the features of claim 1 and a method with the features of claim 15. Preferred or advantageous embodiments of the invention result from the dependent claims, the following description and the attached figures.

The subject matter of the invention is an arrangement for an aircraft, in particular a passenger aircraft. The arrangement has at least or precisely two paneling components which are designed and/or suitable for paneling an aircraft cabin of the aircraft. In particular, the paneling components form an inner wall and/or ceiling paneling of the aircraft. The covering components are preferably designed as flat plates, in particular as panels, and are and/or can be arranged on a supporting aircraft structure.

A gap, also known as a so-called split line, is formed between the two trim components. In particular, the gap has the function of compensating for a relative movement between the fairing components that occurs during flight, for example due to pressure and/or temperature differences. The gap is preferably formed in an installation situation of the paneling components in the longitudinal direction of the aircraft between two paneling components that are adjacent to one another, with the two paneling components being spaced apart from one another via the gap. The gap preferably extends with a constant width between the fairing components in a transverse direction directed transversely to the longitudinal direction of the aircraft.

The arrangement has a device which is designed and/or suitable for dispensing a fragrance and/or air humidifying agent. In particular, the fragrance serves to freshen the air and/or to neutralize odors in the aircraft cabin. The fragrance can be a liquid, a solid or a gaseous medium. In particular, the air humidifier serves to increase air humidity in the aircraft cabin. The fragrance and the air humidifying agent can preferably be combined with one another, for example in the form of an aqueous solution.

The device has a metering unit which is designed and/or suitable for the metered release of the fragrance and/or air humidifying agent into the aircraft cabin. In particular, the metering unit is used for passive and/or active Delivery of the fragrance and/or air humidifier into the aircraft cabin. The dosing unit for dispensing the fragrance and/or air humidifying agent can preferably be actuated automatically and/or manually. The device also has a housing, with the dosing unit being accommodated in the housing. In particular, the housing has an outlet opening through which the fragrance and/or air humidifying agent is released into an environment through the dosing unit.

Alternatively, however, the device can also be designed for the optical and/or acoustic output of information. For example, the device can be designed as an advertising or exit display or room air monitor. Alternatively, the device can be designed to detect fire and/or gases, in particular smoke gases. For example, the device can be designed as a fire alarm. Alternatively, the device can be designed to generate light, e.g. direct or indirect lighting. Alternatively, the device can be in the form of a sensor for recording and/or recognizing objects and/or people. For example, the device can be designed as a motion sensor or a camera. Alternatively, the device can be designed and/or suitable for cleaning the cabin air. For example, the device is designed as an air cleaner and/or odor neutralizer.

Furthermore, the device has a mounting device which is designed and/or suitable for fastening the device in the aircraft cabin. In principle, the housing and the mounting device can be designed as separate components which are connected to one another in a positive and/or material and/or non-positive manner. Alternatively, however, the housing and the mounting device can also be made in one piece or in one piece, e.g. made from a common material section, with the housing having at least one closable mounting opening for mounting the components that are accommodated and/or can be accommodated in the housing. In particular, the mounting device is used for detachable Fastening of the device to the inner lining of the aircraft cabin. In principle, the device can be mounted on the side wall paneling or a dividing wall, also known as a “partition”, of the aircraft cabin. However, the device is preferably arranged on the ceiling lining, in particular in an aisle area, of the aircraft. In particular, several of the devices can be mounted distributed in an aircraft cabin.

In the context of the invention, it is proposed that the mounting device has a mounting hook, with the mounting hook reaching behind one of the paneling components via the gap when the device is in a mounted state, so that the device is held on the paneling component. In particular, during assembly, the assembly hook is connected to the cladding component via the gap by means of a plugging movement and a subsequent rotary movement. The device can be fixed positively and/or non-positively to one of the paneling components via the mounting hook. In particular, the mounting hook is dimensioned in such a way that it can grip paneling components of different strengths or thicknesses. Specifically, the trim hook is formed in the shape of an angle.

The advantage of the invention is that the assembly hook enables particularly simple and quick assembly and disassembly of the device in the aircraft cabin, which can also be carried out without the aid of tools. Furthermore, the mounting hook forms a mounting interface that can be used universally, so that the device can be installed in different aircraft. Another advantage is that the device can easily be retrofitted into existing aircraft that have a corresponding paneling of the aircraft cabin.

In a specific embodiment, it is provided that the mounting device has a flat mounting plate section, with the mounting plate section having a mounting surface on a side facing the cladding component, which, in particular when the device is in the assembled state, is designed and/or suitable for supporting at least one of the cladding components . In particular, the mounting plate section defines an end stop for the mounting device during mounting. In the assembled state, the mounting device is preferably supported in sections via the mounting plate section both on the one trim component and on the other trim component spaced apart by the gap. The mounting hook is connected to the mounting plate section, with the mounting hook protruding from the mounting plate section, in particular the mounting surface. The mounting hook and the mounting plate section are preferably manufactured in one piece, e.g. from a common material section and/or from a single cast. An assembly device is thus proposed which is characterized by a particularly stable and secure assembly of the device.

In a development it is provided that the mounting hook has a standing hook shank and a lying hook shank, the standing hook shank protruding from the mounting surface and the second hook shank rectified to the mounting surface adjoins the first hook leg. In particular, the standing hook shank is aligned perpendicular or at least approximately perpendicular to the mounting surface. In particular, “aligned” should be understood to mean that the lying hook shank is aligned parallel or at least approximately parallel to the mounting surface. "At least approximately vertical" and "at least approximately parallel" are to be understood as meaning an angular deviation of at least +/- 5 degrees. In particular, the standing hook shank extends through the gap in the assembled state, with the lying hook shank reaching behind and/or being supported on the one trim component. In particular, the standing hook shank is arranged with some play in the gap, so that in the assembled state a relative movement in the longitudinal direction of the aircraft is possible between the two fairing components. In the assembled state of the device, the cladding component is arranged in a form-fitting manner between the mounting plate section and the second hook leg. In other words, the cladding component is surrounded on both sides by the mounting device, in particular the second hook leg on one side and the mounting plate section on the other side. An assembly device is thus proposed which is characterized by a simple and robust structure.

In a further embodiment it is provided that the mounting device has at least or precisely one elastically deformable compensating element which is designed and/or suitable for compensating for tolerances and/or different component thicknesses. For this purpose, the compensating element is arranged on the mounting surface. In particular, the compensating element has the function of compensating for component and/or production-related tolerances and/or covering a form-fitting installation on paneling components of different thicknesses. In addition, the compensating element is used in particular for vibroacoustic decoupling between the mounting device and the adjacent paneling components. In particular, the compensating element is made of a compressible material, which is compressed during assembly and, due to its elasticity, compensates for play between the mounting plate section and the cladding component. Optionally, the compensating element serves to increase the coefficient of friction between the assembly device and the at least one trim component, so that the device is also secured against slipping. For example, the compensating element can be made of foam or felt or rubber. In principle, the compensating element can be arranged flat, in particular over the entire surface, on the mounting surface. Alternatively, the compensating element is arranged partially and/or in sections on the mounting surface. In particular, the mounting device has a plurality of the compensating elements, which are distributed and/or arranged at a distance from one another on the mounting surface. The at least one compensating element can be applied to the mounting surface in a materially bonded manner. Alternatively, however, the at least one compensating element can also be designed as an insert part, which is inserted between the mounting plate section and the cladding component prior to assembly. An assembly device is thus proposed which can be used for different paneling components and at the same time ensures stable assembly without play. In addition, vibrations that occur during flight operations can be compensated for by the compensating element.

In a further realization it is provided that the gap is covered by a gap cover, the gap cover being in contact with the fastening hook when the mounting device is in a mounted state. In particular, the gap covering is arranged on a rear side, in particular a non-visible side, of the cladding components.

The gap cover is preferably fixed on one side to one of the cladding components and on the other side rests on the other cladding component and the mounting hooks without a gap and/or sealingly. The gap cover is preferably made of a flexible material, so that the gap cover can be displaced and/or deformed upwards, in particular in an assembly direction of the device. The gap cover is preferably designed as a sealing lip. In particular, the mounting hook, in particular the second hook shank, is designed in such a way that the gap cover rests sealingly on the mounting hook, in particular the second hook shank, when the device is in the mounted state. For this purpose, the second hook leg can be flattened and/or beveled. The second mounting leg preferably has a bevel at the end, which is used to rest against the gap cover. An assembly device is thus proposed which, in the assembled state, ensures a sealing function of the gap cover in the area of the assembly hook.

In a further implementation, it is provided that the dosing unit and/or the housing are fastened to the mounting plate section on a side facing away from the mounting surface. In particular, the dosing unit and/or the housing can be fastened to the mounting plate section in a positive and/or non-positive manner. Preferably the housing and/or the dosing unit are pre-assembled prior to assembly on the mounting plate section. The housing is preferably detachably attached to the mounting plate section, for example via a clip and/or screw connection, so that the housing can be removed at any time, particularly when the device is in the installed state. Alternatively, the housing and the mounting plate section, as already described above, can also be manufactured as one part, with the individual components being able to be mounted in the housing via the mounting opening. The housing can be shell-shaped, with the housing together with the mounting plate section forming a receiving space for receiving the dosing unit. Alternatively, however, the housing can also be self-contained, with the dosing unit accommodated in the housing being fastened to the mounting plate section. A device is thus proposed which is characterized by simple assembly of the individual components which can be disassembled and reassembled in a simple manner, for example for maintenance purposes.

Furthermore, it can be provided that the device has at least or precisely one exchangeable and/or refillable receptacle for receiving the fragrance and/or air humidifying agent. In particular, the receptacle is designed as a flacon. The receptacle can be made of glass or plastic. The receiving container is preferably designed to be transparent, so that the current fill level is visible. The at least one receptacle is in operative connection with the dosing unit. The receiving container can preferably be connected to the dosing unit via a quick-release fastener and/or a plug-in connection, so that the receiving container can be removed or replaced particularly easily and quickly. It is therefore an aspect of the invention to propose a device which is characterized by a sustainable receptacle which can also be connected to the dosing unit in a simple manner.

Optionally, it can be provided that the device has at least or precisely one further receptacle which is designed and/or suitable for holding a further fragrance and/or air humidifying agent. In principle, a fragrance can be accommodated in one receptacle and an air humidifier in the other receptacle. Alternatively, however, different fragrances and/or air humidifiers can also be accommodated in some or in all of the receptacles. Alternatively, the same fragrance and/or air humidifying agent can be arranged in some or all of the receptacles. The device particularly preferably has more than two, preferably more than four, in particular more than six, of the receptacles. In particular, the multiple receptacles can be held together to form an assembly via a common holding device, with the receptacles being interchangeable individually and/or independently of one another. A device is thus proposed which can be configured individually, with different fragrances and/or air humidifiers being able to be combined with one another as desired.

In a further embodiment, it is provided that the dosing unit has at least or precisely one atomization device which is designed and/or suitable for atomizing the fragrance and/or air humidifying agent. In particular, the atomization device is designed to atomize the fragrance and/or air humidifier thermally and/or acoustically and/or mechanically. In particular, the dosing unit has a plurality of the atomizing devices, with each of the receptacles being assigned a separate atomizing device. A dosing unit is thus proposed which ensures an even distribution of the fragrance and/or air humidifying agent in the cabin.

In a further specific implementation, the atomization device is designed as an ultrasonic actuator. In particular, the ultrasonic actuator is designed to atomize the fragrance and/or air humidifying agent, which is designed as a liquid, into an aerosol by means of an electrically excitable piezo element. Alternatively, the atomizing device is designed as an atomizing nozzle. In particular, the atomizing nozzle is designed to atomize the fragrance and/or air humidifying agent, which is designed as a liquid, to form an aerosol when it emerges from the nozzle. Alternatively, the atomizing device is designed as an evaporator. In particular, the evaporator is designed to atomize the fragrance and/or air humidifier, which is designed as a liquid, into an aerosol by means of thermal energy, e.g. a heating wire. A dosing unit is thus proposed which is characterized by its small size and low-noise and drop-free atomization of the fragrance and/or air humidifying agent.

In a further specification, it is provided that the dosing unit has at least one capillary, with the receptacle and the atomizing device being connected to one another via the capillary, and with the fragrance and/or air humidifying agent being and/or being conveyed from the receptacle to the atomizing device by means of the capillary effect is. In particular, the receptacle has a receiving opening tion for receiving the capillary, the capillary being arranged with one end in the receiving container and with the other end in the atomizing device. The ultrasonic actuator or the evaporator are preferably connected to the receptacle via the capillary in order to be supplied with the fragrance and/or air humidifying agent. A dosing unit is thus proposed which is characterized by a cost-effective and efficient design, since no additional pump or the like is required to convey the fragrance and/or air humidifying agent.

In an alternative specification, it is provided that the device has a pump system, with the fragrance and/or air humidifying agent being able to be conveyed from the receptacle to the atomization device by means of the pump system.

In particular, the pump system has at least one pump that generates pressure in order to transport the fragrance and/or air humidifying agent to the associated atomizing device. For example, the pump can be designed as a peristaltic pump, which conveys the fragrance and/or air humidifying agent to the atomizing device via a suction hose protruding into the receptacle. The atomizing nozzle is preferably connected directly to the pump, with the fragrance and/or air humidifying agent conveyed via the pump system being pumped via the atomizing nozzle and being atomized as it emerges. Alternatively, however, the ultrasonic actuator or the evaporator can also be in fluid communication with the receptacle via the pump system in order to be supplied with the fragrance and/or air humidifying agent. A device is thus proposed which ensures reliable transport of the fragrance and/or air humidifying agent to the dosing unit. Furthermore, the receptacle can be arranged individually in the housing, with the fragrance and/or air humidifying agent being transported to the atomizing device via the pump system.

In a further embodiment it is provided that the device has a control device which is designed and/or suitable for controlling the dosing unit. In particular, the control device has the function of controlling the release of the at least one fragrance and/or air humidifying agent by the at least one atomizing device. The control device can be designed as a microprocessor, for example. The control device and the dosing unit are arranged together on a printed circuit board and are connected to one another in terms of signals and/or electrically. In particular, the at least one ultrasonic actuator or the evaporator and/or the pump is/are connected to the control device in terms of signals and/or electrically. The control device is designed to control the dosing unit for releasing the fragrance and/or air humidifier based on time and/or sensors. In particular, a cycle time and/or an atomization duration for the release of the fragrance and/or air humidifying agent can be stored in the sensor device. The plurality of ultrasonic actuators or evaporators and/or pumps can preferably be activated by the control device on the basis of the stored cycle times at the same time and/or with a time delay and/or at regular time intervals to release the fragrance and/or air humidifying agent. Alternatively or optionally in addition, the device has at least one sensor device which is designed to detect air humidity and/or odors in the aircraft cabin. In particular, the sensor device is connected to the control device in terms of signals in order to activate the dosing unit on a sensor-based basis. For example, the sensor device can include a humidity sensor, in particular a hygrometer, for detecting the air humidity. Alternatively or optionally in addition, the sensor device can have a gas and/or odor sensor. A device is thus proposed which is characterized by a situation-dependent and dynamic release of the fragrance and/or air humidifying agent.

In a further specific implementation, it is provided that the device has a connection interface for establishing a wireless connection with an operating device, with the dosing unit being remotely controllable by the operating device. In particular, the operating device has the function of remotely activating or deactivating the device. Optionally, however, different profiles for dispensing the at least one fragrance and/or air humidifying agent can also be selected and/or set via the operating device. The operating device can be in the form of a mobile terminal device or a remote control. Designed as a mobile end device, e.g. smartphone or tablet, the device can be remotely controlled via an app, for example. In particular, the connection interface is designed as a WLAN, Bluetooth, infrared and/or radio interface. A device is thus proposed which is characterized by particularly simple and convenient operation.

In a further refinement, it is provided that the device has an energy supply device for providing electrical energy, the energy supply device is arranged in the housing. The energy supply device serves in particular to supply the electrical components of the device, such as the ultrasonic actuator or vaporizer, pump, connection interface, control device, etc., with electrical energy. The energy supply device is preferably designed as a replaceable battery or accumulator. The energy supply device can preferably be replaced and/or charged by removing the housing or by opening the assembly opening arranged in the housing. Due to the integrated energy supply device, the device can be operated independently of the on-board network and can therefore be easily retrofitted into existing aircraft systems.

In a further specification, it is provided that the housing is designed as a metal housing, with the housing forming fireproof and/or electromagnetic shielding for the electronics arranged therein. The housing is preferably designed as a formed and/or deep-drawn component. In particular, the housing is made of sheet metal. A device is thus proposed which is characterized by improved shielding against electromagnetic fields and at the same time forms a fireproof casing.

• - Drehen der Montageeinrichtung mit dem Montagehaken in einer zweiten Montagerichtung, wobei der Montagehaken quer zum Spalt ausgerichtet wird und eines der Verkleidungsbauteile hintergreift.

A further object of the invention relates to a method for fastening the device as already described above. The procedure includes the following steps:

• - Inserting the mounting device with the mounting hook in the gap formed between the two trim components in a first mounting direction;
• - Rotating the mounting device with the mounting hook in a second mounting direction, the mounting hook being aligned transversely to the gap and engaging behind one of the trim components.

In particular, the assembly hook is inserted into the gap between the two trim components in the first assembly direction by means of an insertion movement. In this case, the first assembly direction is preferably defined by a directional vector directed perpendicularly to the cladding components and/or transversely to the direction of flight. In particular, the mounting hook is inserted into the gap until the mounting plate section with the mounting surface or the at least one compensating element comes into contact with the at least one trim component or is compressed in order to obtain sufficient friction. The mounting hook is then rotated in the second mounting direction by a rotary movement in the gap. The lying hook shank is pivoted in the second assembly direction, so that it is supported on one of the cladding components counter to the first assembly direction. In particular, the lying hook shank is aligned in or against the direction of flight by turning it in the second assembly direction.

1 1 shows an interior view of an aircraft cabin 2 of an aircraft 1 in a three-dimensional representation. For example, the aircraft 1 is designed as a passenger aircraft, with the aircraft cabin 2 being designed as a passenger cabin. The aircraft cabin 2 is divided into a left and right seating area 3a, b and an aisle area 4 arranged between them. Above the right and left seat areas 4, the aircraft 1 has a storage compartment arrangement 5a, b, which are arranged as mirror images of one another.

The aircraft cabin 2 is clad in a ceiling area 6 located between the two storage compartment arrangements 5a, b by a plurality of cladding components 7a, b, in particular ceiling panels. The cladding components 7a, b can be designed as flat or curved panels. The fairing components 7a, b are arranged one behind the other in the longitudinal direction of the aircraft and are spaced apart from one another by a gap 8 . The gap 8 serves to compensate for changes in length in the longitudinal direction of the aircraft, which can occur, for example, due to temperature and/or pressure differences during flight operations.

The aircraft 1 has a device 9 which is designed to dispense a fragrance and/or air humidifier in the aircraft cabin 2 . In particular, the scent can be a scented liquid, for example a scented oil, perfume or the like. The scent can, for example, have a scent that smells like disinfectant, in order to generate a hygienic scent in the aircraft cabin 2 . The air humidifier can be a water-based solution or water and is used to increase the air humidity in the aircraft cabin 2.

The device 9 is mounted in the ceiling area 6 in the area of the gap 8 on or between the cladding components 7a, b. The aircraft 1 can optionally have a plurality of the devices 9 , with the plurality of devices being distributed in the longitudinal direction of the aircraft and preferably being arranged in the ceiling area 6 .

2 and 3 each show the device 9 in a schematic three-dimensional representation as an embodiment of the invention, wherein 2 the device 9 in an assembled state and 3 shown in an exploded view. The device 9 has a mounting device 11 for the detachable mounting of the device 9 in the ceiling area 6 . For this purpose, the mounting device 11 has a mounting hook 12 and a mounting plate section 13 , the mounting hook 12 being arranged on the mounting plate section 13 .

The mounting plate section 13 has a flat mounting surface 14 on a side facing the cladding components 7a, b, the mounting device 11 being able to be supported on at least one of the cladding components 7a, b in a mounted state via the mounting surface 14. The mounting hook 12 has a standing hook shank 12a and a lying hook shank 12b. The standing hook shank 12a protrudes perpendicularly from the mounting surface 14, the lying hook shank 12b directly adjoining the standing hook shank 12a in the same direction as the mounting plate section 13. In particular, the standing and the lying hook shank 12a, b form a right angle. The mounting hook 12 and the mounting plate section 13 are made in one piece, e.g. For example, the mounting plate portion 13 and the mounting hook 12 are made of metal.

The assembly device 11 has several, in particular exactly four, compensating elements 15, which are used to compensate for component tolerances and/or to cover different component thicknesses of the cladding components 7a, b. Furthermore, the compensating element 15 serves to increase the coefficient of friction between the assembly device 13 and the cladding components 7a, b when the device 9 is in the assembled state. The compensating elements 15 are preferably made of an elastically deformable and compressible material. For example, the compensating elements 15 can be made of foam and can be held on the mounting surface 14 in a materially bonded manner, e.g. by means of an adhesive connection.

The device 9 has a housing 16 which is attached to the mounting plate section 13 via a first and a second attachment section 17a, b. For example, the fastening sections 17a, b are each designed as a fastening lug, which is detachably connected to the mounting plate section 13, for example via a clip and/or screw connection. The housing 16 is open on the side facing the mounting plate section 13 , the mounting plate 13 delimiting and/or closing off a receiving space 18 of the housing 16 . The housing 16 is designed as a metal housing in order to ensure fireproof and/or electromagnetic shielding of the electronics arranged therein. For example, the housing 16 is designed as a sheet metal component.

The device 9 has a dosing unit 10 which is used for the dosed release of the fragrance and/or air humidifying agent. The dosing unit 10 is arranged inside the receiving space 18 and fastened to the mounting plate section 13 . The housing 16 has an outlet opening A, with the dosing unit 10 releasing the fragrance and/or air humidifying agent through the outlet opening A to the environment. The dosing unit 10 is fluidically connected to a plurality, in particular exactly three, receptacles 19, with the receptacles 19 each being filled with a fragrance or air humidifying agent. The receptacles 19 are each designed, for example, as a refillable glass bottle.

The device 9 has a holding device 20 which is designed to hold the receptacles 19 together to form a common assembly. The receptacles 19 are each designed to be structurally identical, so that the receptacles 19 can be exchanged with one another. The receptacles 19 can be held in the holder device 20 via a plug and/or screw connection, the holder device 20 in turn being firmly connected to the mounting plate section 13 and/or the dosing unit 10 .

The dosing unit 10 has several, in particular exactly three, atomizing devices 21 on, with one atomizing device 21 each being associated with one of the receptacles 19 . The atomizing devices 21 can be designed, for example, as ultrasonic actuators, which are used to atomize the fragrance and/or air humidifying agent designed as a liquid by means of high-frequency mechanical vibrations, for example more than 2 MHz. Alternatively, however, the atomizing devices 21 can also be in the form of an evaporator or a pump/nozzle combination. The receptacles 19 can each be fluidically connected to the associated ultrasonic actuator via a capillary 22, with the respective fragrance or air humidifying agent being conveyed or being conveyed from the receptacle 19 to the associated ultrasonic actuator by means of the capillary effect.

The ultrasonic actuators 21 are arranged together on a printed circuit board 23, the ultrasonic actuators 21 being connected to a common control device 24 via an electrical line, e.g. The control device 24 is used to control the individual ultrasonic actuators 21, for which purpose a cycle time and/or an atomization duration for each of the ultrasonic actuators 21 is stored in the control device 24, for example. For example, the ultrasonic actuators 21 can be activated by the control device 24 at the same time, with a time delay and/or at fixed time intervals. For example, the control device 24 is designed as a microprocessor.

An energy supply device 25 is arranged in the receiving space 18 and is designed to supply, for example, the control device 24 and the ultrasonic actuators 21 with electrical energy. In the exemplary embodiment shown, the energy supply device 25 is formed by two batteries. Alternatively, however, the energy supply device 25 can also be in the form of an accumulator or mains connection for connection to the vehicle electrical system. The device 9 can optionally have a DC-DC converter 26 which can be arranged either on the printed circuit board 24 or the mounting plate section 13 within the receiving space 18 .

Furthermore, the device 1 has a connection interface 27 which is set up to establish a wireless connection with an operating device, not shown. The connection interface 27 can, for example, be in the form of a receiving module, with the operating device being equipped with a corresponding transmitting module. For example, the transmitter and the receiver module can communicate with each other via a WLAN connection. The operating device can, for example, be in the form of a mobile end device, e.g. smartphone, tablet, or a remote control. In particular, the operating device is designed to transmit a control signal to the connection interface 27 via the wireless connection, with the control device 24 being designed to control the dosing unit 10 or the atomizing device 21 on the basis of the control signal. For example, the device 9 can be switched on or off via the operating device. Optionally, different profiles for releasing the fragrance and/or air humidifier can be selected and/or set via the operating device.

The 4 until 6 each show an arrangement 30 for the aircraft 1, with the device 9 and a first and a second fairing component 7a, b, as shown in FIG 1 already described, in different states of assembly. The fairing components 7a, b are spaced apart from one another in the longitudinal direction F of the aircraft by the gap 8, with the gap 8 being covered by a gap cover 28. The gap cover 28 is arranged on an inner side or a non-visible side of the cladding components 7a, b, the gap cover 28 being fixed to the first cladding component 7a and sealingly abutting the second cladding component 7b. For example, the gap cover 28 is designed as a flexible sealing lip.

In 4 the device 1 is shown in a dismantled state, with the device 1 being inserted into the gap 8 for assembly with the assembly hook 12 in a first assembly direction M1. The mounting hook 12 is aligned with the lying hook shank 12b along the course of the gap, so that the mounting hook 12 can be inserted unhindered between the two paneling components 7a, b.

The device 1 is moved in the first assembly direction M1 until the assembly plate section 13 is supported with the assembly surface 14 or the compensating elements 15 on the lining components 7a, b, as is shown in 5 is shown. In the process, the compensating elements 15 are at least partially compressed in order to compensate for play in the assembly direction M1 between the cladding components 7a, b and the assembly device 13. During assembly, the gap cover 28 is displaced in the assembly direction M1 by the assembly hook 12 or lifted from the second cladding component 7b, so that the assembly hook 12 with the lying assembly leg 12b can engage behind the second cladding component 7b. For this purpose, the device 9 in a second assembly direction M2 relative to the cladding components 7a, b rotated by about 90 degrees. The mounting hook 12 with the standing hook shank 12a is rotated within the gap 8, with the lying hook shank 12b being pivoted in the second mounting direction M2 and engaging behind the second paneling component 7b, as is shown in FIG 6 is shown. The device 9 is now in an assembled state and is captively held on the cladding components 7a, b.

In the assembled state, the device 9 is positively fixed to the cladding components 7a, b at least in the first assembly direction M1, with the second cladding component 7b being arranged in a form-fitting manner between the mounting plate section 13 and the lying hook shank 12b. In particular, the lying hook leg 12b and/or the exit opening A are aligned in the longitudinal direction F of the aircraft in the assembled state. The standing hook leg 12a is preferably dimensioned in such a way that it is arranged with play in the gap in the longitudinal direction F of the aircraft, so that a relative movement between the two paneling components 7a, b is possible.

In the assembled state of the device 9, the gap cover 28 rests sealingly against the second lining component 7b and the lying hook shank 12b, with the gap cover 28 being molded onto the lying hook shank 12b for this purpose. In addition, the lying hook leg 12b can be designed in such a way that a gap-free application of the gap cover 28 and thus the sealing function of the gap cover is ensured. For this purpose, the lying hook shank 12b has a bevel 29 at the end, as shown in 2 and 3 shown on, which serves to abut the gap cover 28.

The assembly device 11 enables the device 1 to be assembled in the aircraft cabin 2 quickly, without tools and without any complications. Furthermore, an aircraft-independent assembly is proposed, with the device 9 being compatible or retrofittable for all aircraft types and programs.
