Description

 FRAGRANCE CARTRIDGE AND DEVICE FOR DELIVERING FRAGRANCES AND METHOD FOR

CONTROL

The invention relates to a fragrance cartridge, a device for dispensing fragrances and a method for controlling the device according to the preambles of claims 1 and 20 or 27 and 28.

Devices of this type are used in particular to improve the indoor air and for therapeutic purposes to carry out what is known as aromatherapy. Numerous devices for the emission of fragrances are known from the prior art. The subject of EP 0 004 039 B1 is, for example, a liquid atomizer, in which the liquid to be atomized is conveyed to a nebulizer plate using a wick and the atomizer plate is excited by a vibration generator. From the German utility model DE 296 21 752 Ul, for example, a device for distributing fragrances is known, in which a fan blows onto a distributor mat, which is soaked from a tank, a solenoid pump conveying the oil through a cannula from the tank to the distributor mat. A disadvantage of the prior art is that the known solutions either require a technically complex pump mechanism or rely on conveyance by means of capillary action. With the aid of the capillary action, it is not possible to control the conveyance, since there is constant funding. This leads to even when the device is not desired to be used a fragrance distribution or a fragrance consumption. Furthermore, a fragrance distributor is known from US 4,200,229, which consists of a stationary holder and a replaceable fragrance cartridge. The liquid is pumped into a pillow by a hand-operated pump. The disadvantage of this is that lines with a small inner diameter tend to clog. It is disadvantageous in all devices that they do not enable the fragrance release to the environment to be effectively switched off, since the impregnated carriers regularly release fragrance to the environment even after a fan or other distributor which may be present is switched off.

The object of the invention is to propose a fragrance cartridge and a device for dispensing fragrances and a method for controlling or regulating the device, which allow reliable and controllable forwarding of the fragrance medium to the material by a simple structure and a simple process Releases fragrance and continue to allow effective stopping of fragrance delivery in the shortest possible time.

This object is achieved on the basis of the features of the preamble by the characterizing features of claims 1 or 20 or 27 or 28. Advantageous designs and developments of the invention are possible due to the features mentioned in the subclaims.

The invention relates to a fragrance cartridge for a device for dispensing fragrances, in this case the fragrance cartridge comprises at least one container which has at least one cavity for receiving a fragrance medium which opens to an environment, a metering device closing the opening, in this case it is particularly provided that the ^' metering device has a piston which passes through the opening in the container in a first and a second End positions can be moved, the end positions being opposite each other and the piston in the first end position being at least partially in an impregnation position within the container and the piston in the second end position being in a fragrance dispensing position and being at least partially outside the container. With a fragrance cartridge, which is equipped with such a metering device or such a metering valve, it is possible to convey the liquid or gaseous fragrance medium from the container into the environment without the risk that small diameter hose lines become blocked. The piston forms a transport medium that serves to temporarily store the fragrance medium. Since the piston can be moved back into the cavity sealed off from the surroundings, the fragrance delivery can be switched off quickly. The scent-releasing piston is encapsulated in the cavity after the retraction. .

An advantageous embodiment of the subject matter of the invention provides for the piston to be assigned at least one seal and in particular two seals. This makes it possible to seal the piston or the cavity in the first and in the second end position from the surroundings and to prevent the fragrance medium from escaping from the fragrance cartridge. In particular, it is intended to use seals made of Teflon, since these are particularly resistant to aggressive fragrance media.

According to a particular embodiment of the subject matter of the invention, provision is made to seal the cavity from the outside with the first seal and to seal the cavity from the inside with the second seal. As a result, the metering device is particularly simple. This allows a simple and inexpensive assembly of the dosing device. The invention provides for the use of a piston which allows the fragrance medium to be temporarily stored in at least one section. As a result, the volume of the accumulator and its position on the piston can be freely selected and can be easily adapted to the respective requirements.

A special embodiment provides for at least one cavity to be formed in the piston, which cavity is closed by a grille and receives a material which is suitable for storing the fragrance medium. In such a cage, it is possible storage body or impregnating body with different properties such. B. use different pore sizes without changes to the design of the piston are required.

The invention provides to use, in particular, open-pore plastics or foams, in particular made of polypropylene or polyethylene, or open-pore ceramic elements or nets made of Teflon as the material for the storage body, the nets for forming a storage body, for. B. be wound up. Sponge-like storage bodies constructed in this way allow the preferably concentrated essential or natural oils used as the fragrance medium to be stored.

Furthermore, the invention provides for the metering device to be equipped with a spring element, by means of which the piston is pressed into the first end position. This ensures that the piston is always in a position in the delivery state of the fragrance cartridge or in the idle state of the fragrance cartridge, in which it is largely inserted into the cavity and in which the cavity is sealed from the environment. This effectively prevents the undesired escape of fragrance medium. According to the invention, the metering device is constructed from a closure cap in which the piston is guided. This makes it possible to design the metering device as a preassembled unit that only has to be placed on the container in order to form a functional fragrance cartridge.

A particularly advantageous embodiment of the invention provides for the closure cap and the container to be provided with a thread in order to be able to screw the closure cap onto the container. A fragrance cartridge composed in this way allows efficient production and is also ideally suited for later separation of the valuable materials or refilling.

Furthermore, it is provided to arrange at least one guide element on the closure cap, on which the piston is guided. This support option for the piston limits its load due to laterally acting forces when it passes through the closure cap. In this way, leaks are effectively prevented, which could be caused by transverse loads or inclined positions of the piston. Furthermore, the guide supports a smooth, easy sliding of the piston between the end positions.

According to the invention in particular guide elements are provided which are designed as a rail or as a rod. These can easily be injected onto the sealing cap, for example by injection molding.

The invention also provides for the container to be made of glass, in particular as a glass bottle, since fragrance media often contain aggressive substances.

It is advantageous to place the fragrance cartridge on the container in particular and / or to provide the metering device with at least one projection and / or one recess. This allows the fragrance cartridge or its individual parts to be handled easily in the production process and during filling. Furthermore, this enables the fragrance cartridge to be positioned precisely in the device.

According to an embodiment variant, it is provided that the piston is formed at least in two parts. In the case of a piston with stops or a piston with seals that protrude beyond the circumference of the piston, this allows the piston to be easily mounted on the closure cap, since the piston can be inserted into a through hole in the closure cap from two sides.

The invention also provides for the seal to be designed as a seal plate. This shape makes it easy to install the seals on the piston. Furthermore, these seals allow easy monitoring of their function.

According to an embodiment variant, the invention provides for the use of piston ring seals as seals. These seals also allow the piston to be sealed against the container or cap during movement between the end positions.

A third embodiment provides for the seal to be designed as a stuffing box, the stuffing box being mounted in particular in the container or in the sealing cap. When using a stuffing box, a single seal is sufficient to seal the piston or cavity from the environment.

According to the invention it is further provided to arrange at least one stop on the piston. This will be a undesired wide movement of the piston beyond an end position avoided. In particular, it is provided that the stop strikes the container and / or the closure cap.

Furthermore, the invention relates to a device for dispensing fragrances with a fragrance cartridge described above, which is detachably held in the device. It is provided here that the piston of the fragrance cartridge is moved by first control means of the device from the first end position to the second end position or from the second end position to the first end position. With this simple sequence of movements, it is possible to switch the fragrance cartridge on or off. For switching on and off, only the time for moving the piston is required. When the piston is switched off, it is moved back into the container and received in a sealed manner so that no further fragrance is emitted by the piston.

An advantageous embodiment of the subject matter of the invention provides for the fragrance cartridge to be rotated by second control means in order to completely soak the piston or the material arranged in or on the piston. This makes it possible to use short pistons and to use the fragrance medium contained in the fragrance cartridge completely for scenting, without having to leave any residual amounts in the fragrance cartridge.

The invention further provides to control the first and / or second control means with the aid of third control means. This enables compliance with a predefined movement sequence and prevents incorrect controls compared to an independent actuation of the first and second control means.

According to the invention, the control means are mechanical and / or electro-mechanical and / or electronic control means. In particular, levers, link guides, traction means and gears are provided as mechanical control means. The invention provides in particular electric motors, pneumatic cylinders and electromagnets as electromechanical control means. In the case of electronic control means, in particular integrated circuits are provided according to the invention.

Furthermore, it is provided to regulate the control means by means of a superordinate electronic regulation or to assign an electronic regulation to the control means. This ensures the planned interaction of the individual components or the interaction with other components.

In addition, it is provided to connect at least one sensor to the control. This makes it possible to react to other parameters in the control.

An advantageous embodiment of the subject matter of the invention provides for the device to be assigned at least one fan by means of which the piston can be exposed to an air flow in the fragrance dispensing position. This enables the fragrance to be distributed over a wide area.

According to the invention, a step-by-step or stepless regulation of the performance of the fan is also provided. This makes it possible to meet individual circumstances and requirements.

Finally, the invention relates to a method for controlling or regulating the device for dispensing fragrances described above, with the following steps. Firstly, rotating the fragrance cartridge from an upright basic position, in which the piston is approximately vertical about 90 ° to 180 ° into a loading position, the piston being in the first end position; Second, holding the fragrance cartridge in the loading position to soak the liquid absorbent material; Thirdly, swiveling the fragrance cartridge back into the basic position, fourthly lifting the piston into the second end position; Fifth blowing on the piston to release fragrances and sixth moving the piston back to the first end position. Such a method allows repeated, controllable indication of fragrance in an environment.

Alternatively, a further method for controlling or regulating the above-described device for dispensing fragrances is provided with the following steps: firstly lifting the piston from the first end position into the second end position; Second, puffing the plunger to release fragrances and third, moving the plunger back to the first end position. Such a method also allows repeated, controllable release of fragrance into an environment.

Cut areas are generally not hatched in the figures in order to maintain the clarity of the figures.

A first fragrance cartridge 1 is shown schematically in different operating positions in FIGS. First follows a basic description of the fragrance cartridge 1 with reference to FIG. The fragrance cartridge 1 comprises a container 2 with a cavity 3, the cavity 3 receiving a liquid fragrance medium 4. The container 2 has an opening 5 with which the cavity 3 opens to an environment 6. The opening 5 is closed by a metering device 7. The metering device 7 comprises a piston 8, which at its front ends 9 and 10 each have a seal 11 and a seal 12. The seals 11 and 12 are designed as seal plates 13 and form stops 14 and 15. The opening 5 in the container 8 forms a sliding guide 16 for the piston 8, in which the piston 8 can be moved in the arrow directions x and x '. The piston 8 can be moved from a first end position A shown in FIG. 1 a to a second end position B shown in FIG. 1 c in the direction of the arrow x. Since the piston 8 is pressed into the end position A by a spring element 17, a force F is required for moving into the second end position B. The spring element 17, which is designed as a helical spring 17, is supported on an inner wall 18 of the container 2 and acts on the piston 8 via the second seal 12. In the first end position A, the first seal 11 forms the stop 14 and seals it Interior 3 of the container 2 from the outside in relation to the environment 6. Here, the stop 14 rests on an outer wall 19 of the container 2 and prevents the piston 8 from being pulled further into the cavity 3 by the spring element 17. In the second end position B of the piston 8 (see FIG. 1c), the second seal 12 forms the stop 15, which bears against the inner wall 18 of the container 2 and prevents the piston 8 from being pulled out further in the direction of the arrow x. In the second end position B, the spring element 17 is completely compressed and lies in an annular recess 20 in the container 2. Furthermore, the seal 12 seals the interior 3 of the container 2 from the surroundings 6. The piston 8 consists of a material 21, for example a porous ceramic body, which is suitable for receiving the fragrance medium 4. In principle, the following procedure is provided for dispensing fragrance to the environment 6: the fragrance cartridge 1 is turned from an upright basic position G (see FIG. 1 a) by about 180 ° into an impregnation position T (see FIG. 1 b), the piston 8 in the the first position A is a piston setting position A. In the impregnation position T of the fragrance cartridge 1 is the Piston 8 or the impregnable material 21 from which the piston is made is completely surrounded by the fragrance medium 4. Leakage of the fragrance medium 4 is prevented in the impregnation position T by the first seal 11. After the impregnation, the fragrance cartridge 1 is turned back from the impregnation position T into the basic position G by approximately 180 ° and the piston 8 is raised in the direction of the arrow x. In this second end position B of the piston 8, which is a fragrance delivery position B, the fragrance medium 4 received by the piston 8 is released to the surroundings 6. By releasing the piston 8, it springs back into the first end position A and the scenting process is ended, whereby a further release of fragrance to the surroundings 6 by the piston 8 is prevented. In the first end position A, the piston 8 is again completely received in the interior 3 of the container 2, so that it can be said that the fragrance cartridge 1 is switched off. When using a gaseous fragrance medium 4, it is generally not necessary to assume the impregnation position T through the fragrance cartridge 1, since the piston is already completely surrounded by the fragrance medium 4 in the basic position G of the fragrance cartridge and can absorb it.

A second fragrance cartridge 1 is shown schematically in different operating positions in FIGS. 2a to 2c. The description of FIGS. 1 a to 1 c basically also applies to FIGS. 2 a to 2 c. In contrast to the embodiment shown in the figures la to lc aroma cartridge Figures 2a-2c is a fragrance cartridge 1, which has a piston 8 which extends into the first end position A, due to its length 1 ₈ to a bottom 22 of the container. 2 Thus, as in the case of the fragrance cartridge shown in FIGS. 1 a to 1 c, a distinction cannot be made between a basic position G of the fragrance cartridge 1 and an impregnation position T of the fragrance cartridge 1, since it is not necessary to rotate the fragrance cartridge 1. The fragrance cartridge 1 is thus simultaneously in the positions G and T. Furthermore, the piston 8 does not consist of one Material for receiving the fragrance medium 4, but has a cage 24 delimited by a grid 23, which is filled with material 21 for receiving the fragrance medium 4. To release the fragrance medium 4 stored in the material 21, the piston is moved against the force of a spring element not shown in FIGS. 2a to 2c from the first end position A (see FIG. 2a) via an intermediate position Z (see FIG. 2b) to the second end position B. (see Figure 2c) raised. In the second end position B, the piston 8 or the material 21 arranged in the cage 24 releases the absorbed fragrance 4 to the surroundings 6. The fragrance cartridge 1 is "switched off" by moving the piston 8 back into the first end position A, which is shown in FIG. 2a. In contrast to the sequence shown in FIGS. 1 a to 1 c, the fragrance cartridge 1 shown in FIGS. 2 a to 2 c is in the basic position G during all the steps; it is not necessary to turn the fragrance cartridge 1 here.

A third fragrance cartridge 1 is shown schematically in FIG. 3a. The description of FIGS. 1 a to 1 c basically also applies to FIG. 3 a. In contrast to the fragrance cartridge shown in FIGS. 1a to 1c, FIG. 3a shows a fragrance cartridge 1 with a differently designed metering device 7. The metering device 7 comprises a closure cap 25 which is screwed to a neck 26 of the container 2 (the threads are not shown) and protrudes through the opening 5 of the container 2 into the interior 3 thereof. The piston 8 is mounted in a cylindrical passage 27 of the closure cap 25. The piston 8 or the interior 3 is sealed against the closure cap 25 or the environment 6 via the two seals 11 and 12, which are designed as piston ring seals 28. At the front ends 9 and 10 of the piston 8, stops 14 and 15 are formed, which in the end positions A and B of the piston 8 (see also FIG. 3e) on an upper side 29 or an underside 30 of the sealing cap 25. A pocket 31 is formed on the upper stop 14, into which a lever 101 (see, for example, FIG. 3b or 3c) can be inserted. Furthermore, the piston 8 does not consist of a material for receiving the fragrance medium 4, but has a cage 24 which is delimited by a grid 23 and which receives material 21 which is suitable for temporarily storing the medium 4. Axle stubs 32 and 33 are formed on the container 2 of the fragrance cartridge 1 and are provided for rotatably suspending the fragrance cartridge 1 about an axis of rotation D ₂ . The axle stub 32 has a flattened area 34, so that the axle stub 32 can be coupled in a rotationally fixed manner with a rotary knob 103 (see FIG. 3b).

FIG. 3b shows a device 100 for dispensing fragrances, into which the fragrance cartridge 1 shown in FIG. 3a can be inserted. The device 100 essentially comprises a housing 102, on which the already mentioned lever 101, the already mentioned rotary knob 103 and a fan 104 are mounted. Furthermore, two legs 105 and 106 are formed on the housing 102, which have bores 107 and 108 for mounting the stub axles of the fragrance cartridge about axes of rotation D ₂ .

FIG. 3c shows the device 100 shown in FIG. 3b, the fragrance cartridge 1 shown in FIG. 3a being inserted into the device 100. The fragrance cartridge 1 is here in a basic position G, the device 100 being in a rest position I. The lever 101 forms first control means S _α , with which the piston 8 can be raised from the first end position A to the second end position B (see FIG. 3e). For this purpose, the lever 101 engages in the pocket 31 of the stop 14 and is moved upward in an arrow direction x. The pocket 31 is open towards the viewer. The rotary knob 103 forms second control means S ₂ , by which a rotation of the Fragrance cartridge 1 around the axis of rotation D _{2 is} possible. For this purpose, there is a non-rotatable plug connection between the rotary knob 103 and the stub shaft 32, which is designed as an extension of the container 2. The fragrance medium 4 is at a level N _G in the interior 3 of the container 2. The material 21 stored in the piston 8 for receiving the fragrance medium 4 is above the level N _{G of} the fragrance medium 4.

FIG. 3d shows the device 100 shown in FIG. 3c in a filling position II, the fragrance cartridge 1 being in an impregnation position T. The fragrance cartridge 1 is transferred from the basic position G shown in FIG. 3c to the watering position T shown in FIG. 3d by rotating the rotary head 103 by 180 ° about the axis of rotation D ₂ . By turning the fragrance cartridge 1, the stop 14 and the lever 101 are separated from each other. In the impregnation position T, the material 21 for receiving the fragrance medium 4 is completely in the fragrance medium 4, which fills the fragrance cartridge 1 in the impregnation position T up to a level N _τ . After soaking, the fragrance cartridge 1 is then turned back into the basic position G shown in FIG. 3c by means of the rotary knob 103 or the second control means S ₂ . Here, the lever 101 engages again in the stop 14. Thus, the stop 14 or the piston 8 can be moved from the first end position A to the second end position B after turning back by the lever 101 or the first control means Si (see FIG. 3e).

FIG. 3e shows the device 100 in the fragrance position III described above, in which the fragrance cartridge 1 is held in the basic position G and the piston 8 has moved into its second end position B with the freshly soaked material 21. For this purpose, the lever 101 or the first control means S _x on the housing 102 was moved in the direction of the arrow x. In the second end position B of the piston 8, the piston 8 is so far out of the container 2 or the closure cap 25 pulled out that the material 21 impregnated with the fragrance medium 4 is located outside the container 2 and outside the closure cap 25 in a freely accessible manner in an interior 109 of the device 100. The material 21 or the piston 8 is preferably exposed to an air flow 110 by the fan 104 in order to at least temporarily achieve a rapid distribution of the fragrance medium in the environment 6 outside the housing 102. For this purpose, the housing 102 has openings, not shown, which enable air to be exchanged between the interior 109 and the surroundings 6. The scenting of the surroundings 6 is brought about by switching off the fan 104 and retracting the piston 8 into the first end position A with the aid of the lever 101. The device 100 is then again in the idle state shown in FIG. 3c.

According to an embodiment, not shown, it is provided to design the first and second control means as electromechanical control means, each of which consists of an electric motor and mechanical components. To control the first and second control means, a third control means is provided, which is designed, for example, as control electronics which at the same time also controls the operation of the fan.

A fourth embodiment of a fragrance cartridge 1 is shown in different representations in FIGS. 4a to 4n. FIG. 4a shows a side view of the fragrance cartridge 1. From the fragrance cartridge 1, a container 2, a closure cap 25 and a cover 35 for the closure cap 25 can be seen.

FIG. 4b shows a section through FIG. 4a along the section line IVb-IVb. The container 2 has a neck 26 with an external thread 36, onto which the closure cap 25 is screwed, which has an internal thread 37 owns. A bracket 38 is formed on the closure cap 25 and is used to fix the fragrance cartridge 1 in the correct position in a device 100 (see, for example, FIG. 5c).

FIG. 4c shows a perspective illustration of the fragrance cartridge 1 already shown in FIG. 4a. Here it can be seen how the bracket 38 runs around the closure cap 25 in a bead-like manner.

FIG. 4d shows the section indicated in FIG. 4a in a perspective view. The closure cap 25 and a piston 8 together with further components form a metering device 7 which can be screwed onto the container 2.

FIG. 4e shows a side view of the fragrance cartridge 1 with the cover unscrewed. The piston 8 is visible above the closure cap 25. A guide element 39 is formed on the closure cap 25, which extends in an arrow direction x and forms a guide which has a T-groove. In this T-slot of the guide element 39, the piston 8 is guided with a web 40 which is T-shaped in cross-section in order to prevent the piston from tilting during an up and down movement from the first end position A to the second end position B (see, for example, Figure 4k) to avoid by side forces. The web 40 itself is stabilized by a first plate 41, under which a first seal 11 is located. The seal 11 closes the container 2 in the first end position A of the piston 8 shown in FIG. 4e.

FIG. 4f shows a view of the fragrance cartridge 1 from the arrow direction IVf shown in FIG. 4e. In this view, the web 40 is covered.

FIG. 4g shows a section through FIG. 4f along the section line IVg-IVg. In addition to the upper plate 41 and the first seal 11, there is also a lower one in FIG. 4g Plate 42 and the second seal 12 visible, which belong to the piston 8. The material 21 for receiving the fragrance medium 4 is arranged in an interior 3 of the container 2 between the seals 11 and 12. This has approximately the shape of a cylinder, the diameter d ₂ . of the impregnation body 21 is dimensioned smaller than the diameter du and i _{2 of} the seals 11 and 12. It is thus possible for the impregnation body to pass through the cylindrical passage 27 of the closure cap 25 in the direction of the arrow x or x '. The cylindrical passage 27 is formed by a shoulder 43 of the closure cap 25. An upper side 29 of the shoulder 43 forms a support surface 29 for the first seal 11 and an underside 30 of the shoulder 43 forms a support surface 30 for the second seal 12. The piston 8, which can be moved in the closure cap 25 in the arrow directions x and x ' , consists essentially of a lifting tube 44, on which the web 40 and the plate 41 are formed, and the second plate 42, which is formed by a cap 45 which is placed on the lifting tube 44. The piston 8 also includes the sealing rings 13, which hold the impregnating body 21 between them. The metering device 7 is completed by a pin 46 which runs in a cylindrical interior 47 of the lifting tube and has a mushroom-shaped first end 48. The first end 48 forms a first counter bearing 49 for a spring element 17. A second counter bearing 50 for the spring element 17 is formed by the cap 45. A second end 51 of the pin 46 is designed as a basket 52, which is supported from below on the shoulder 43 of the closure cap 25. According to an embodiment, not shown, the pin and the basket are made in two parts and are preferably held together by means of a snap connection.

FIGS. 4h to 4j show FIGS. 4e to 4g in a perspective view. It can be seen from FIG. 4h that the closure cap 25 unites in the area of the bracket 38 Has projection 53, which is provided for positive engagement in the device 100.

FIG. 4i clearly shows the T-shaped cross section of the web 40, the T-groove formed in the guide element 39 not being shown in detail to simplify the figures.

FIG. 4j clearly shows the basket 52 formed on the second end 51 of the pin 46. The basket is essentially formed by arms 54, which merge into a ring 55, which rests on the closure cap 25 and against a shoulder 43 of the closure cap 25 supported. A seal 56 is arranged between the container 2 and the closure cap 25 in order to seal the two components against one another. Lifting the piston 8 or the lifting tube 44 from the first end position A shown in FIGS. 4a to 4j causes the cap 45, which is fixedly connected to the lifting tube 44, and thus the seals 11 and 12 and the impregnating body 21 to be carried along. The lifting of the piston 8 and the components firmly connected to it take place against the force of the spring element 17. When the piston 8 is lifted in the direction of the arrow x, the spring element 17 is increasingly compressed by the counter bearing 50 formed by the cap 45. The pin 46 remains unchanged because it is supported on the closure cap 25 by means of the basket 52. The piston 8 thus forms a movable part of the metering device 7 and the pin 46 together with the basket 52 forms a fixed part of the metering device 7. Before the piston 8 is lifted, the impregnating body 21 is regularly soaked. This can be done in the interior 3 of the container 2 liquid 4 penetrate to the impregnating body 21 through gaps 57, which are formed between the arms 54 of the basket 52. In the embodiment of the fragrance cartridge 1 shown in FIGS. 4a to 4n, the impregnation takes place in particular when the fragrance cartridge 1 from the one shown upright position G is pivoted about 90 ° to 180 °. To lift the piston 8, a device 100 (see, for example, FIG. 5h) engages in particular on a cover 58 of the lifting tube 44.

FIG. 4k shows a side view of the metering cartridge 1, the piston 8 being in the second end position B here. This illustration is to be considered in particular in comparison with FIG. 4f, which shows the metering cartridge in the same view in the first end position A of the piston 8. In the second end position B, the piston 8 is pulled out of the container 2 or the closure cap 25 to such an extent that the impregnating body 21 protrudes almost completely over the upper side 29 of the closure cap 25.

FIG. 41 shows a section through the fragrance cartridge 1 shown in FIG. 4k along the section line IV1-IV1. In the second end position B of the piston 8, the pin 46 is in an unchanged position relative to the container 2 or to the closure cap 25. The spring element 17 is now more compressed between the mushroom-shaped end 48 of the pin 46 and the counter bearing 50 formed by the cap 45 The interior 3 of the container 2 is sealed in position B of the piston 8 by the second seal 12, which is pressed by the plate 42 against the underside 30 of the annular shoulder 43 of the closure cap 25. The piston 8 is pressed from the second end position B into the first end position A by the compressed spring element 17, the spring element 17 being relaxed here by the counter bearing 50 moving back into the container 2 in the direction x ′. Even in the first end position A (see, for example, FIG. 4g), the spring element 17 still presses the piston 8 via the counter bearing 50 in the direction of the arrow x '. This ensures that the seal 11 rests with pressure on the closure cap 25 and in the first end position A a good seal of the interior 3 from the environment 6 is given. In a departure from the illustration in FIG. 41, the invention provides according to one embodiment variant that the web 40 is still guided in the guide element even in the end position B. This is achieved, for example, by means of an extended guide element or a lower piston stroke.

Figures 4k and 41 are shown in Figures 4m and 4n in a perspective view. FIG. 4 m shows the contact surface 29 on which the seal 11 comes to rest in the first end position A of the piston 8. The closure cap 25 has a further thread 59, which is provided for screwing on the cover 35 (see FIG. 4a).

FIG. 4n shows a stroke h ₈ which the piston 8 has between the first end position A and the second end position B. The representation of the spring element 17 was partially omitted in FIGS. 4a to 4n in order to maintain the clarity of the figures.

FIGS. 5a to 5j show the above-mentioned device 100 for operating the fragrance cartridge 1 shown in FIGS. 4a to 4n.

FIG. 5a shows the device 100 in a side view, a housing 102 being shown cut away. The housing 102 essentially consists of a first housing part 117a and a second housing part 117b. The fragrance cartridge 1 is held in a form-fitting manner in a holder 111, with an arm 112 engaging over the bracket 38 of the fragrance cartridge 1. Gears 113 and 114 are connected in a rotationally fixed manner to the holder 111 (see also FIG. 5c). Axle stubs 115 and 116 are integrally formed on the gear wheels 113 and 114, which are rotatably mounted about bores in the bores of the second housing part 117b (not shown) about an axis of rotation D _III . The housing part 117b can be _swung out around the axis of rotation Dα7 from the housing part 117a together with the holder 111 for the fragrance cartridge 1. As a result, the fragrance cartridge 1 is easily accessible and consequently easy to replace. A fan 104 is arranged in the housing 102, which draws in ambient air through openings (not shown) on a rear side 118 of the housing 102 and blows it into the surroundings 6 on a front side 119 of the housing 102 through openings (not shown). The piston 8 of the fragrance cartridge 1 lies in this air flow 110. However, the piston 8 in FIG. 5a is in the first end position A, in which no dispensing of fragrance by the metering device 7 is provided. The basic operational readiness of the fan 104 is controlled via a lever 120 which is arranged on a bridge 121 so as to be rotatable about an axis of rotation D ₂ o. The lever 120 carries a permanent magnet 123 at a first end 122. The permanent magnet 123 interacts with a sensor 124 which is arranged on a circuit board 125. The position shown in FIG. 5a is taken by the first lever 120 when the fragrance cartridge 1 is in the first end position A. In this position, the sensor 124 detects the permanent magnet 123 and switches off the fan 104 by means of control electronics 126 arranged on the circuit board 125. In this switch-off position, the first lever 120 is held by a spring 127. A second end 128 of the first lever 120 is actuated in the second end position B of the fragrance cartridge 1 by the cover 58 arranged on the piston 8 (see FIG. 5h). The spring 127 is then compressed.

The holder 111 for the fragrance cartridge 1 interacts with a swing bridge 129 via the toothed wheels 113 and 114. The swing bridge 129 (see also FIG. 5c) is suspended on the housing part 117b so as to be rotatable about an axis of rotation D ₁₂₉ and is formed in some areas as a tooth segment 130 and as a fork 131. The swing bridge 129 interacts with the gear wheels 113 and 114 via the tooth segments 130. The swing bridge 129 and the holder 111 together form a second mechanical control means S ₂ , which is capable of causing the fragrance cartridge 1 to rotate. Over the forks

131, the swing bridge 129 is caused to rotate about the axis of rotation D ₁₂₉ in an arrow direction m. This causes the gearwheels 113 and 114 to rotate in the opposite direction of the arrow n about the axis of rotation Dm via the toothed segments 130, so that the holder 111 together with the fragrance cartridge 1 move from a basic position G in the direction of the arrow n about the axis of rotation Dm to an impregnation position T (see Figure 5d) rotates. The second mechanical control means S ₂ are actuated by third mechanical control means S ₃ . The third control means S ₃ are by a switch mechanism

132 formed. The switch mechanism 132 comprises a button 133, which is rotatably attached to the housing part 117b about an axis of rotation Dι ₃₃ . Numerous levers are actuated by the key 133, which control the second control means S ₂ and the first control means S _λ as the third control means S ₃ . The first control means S _x essentially comprise a lifting fork 134, which is provided for lifting the piston 8. For this purpose, the lifting fork 134 with lugs 135 engages under the cover 58 of the piston 8 (see also FIG. 5h).

5b shows only the housing part 117b of the housing 102 shown in FIG. 5a. The second housing part 117b can be pivoted out of the first housing part 117a via the axis of rotation D _U7 . If necessary, the two housing parts 117a and 117b can also be separated from one another. Only mechanical components are arranged in the second housing part 117b. The electrical and electronic components are located exclusively in the housing part 117a.

FIG. 5c shows FIG. 5b from the direction of the arrow Vc. The control means S, S ₂ and S ₃ are substantially symmetrical with a center line M Device 100 constructed. For example, the swing bridge 129 has the two forks 131 and the two gearwheels 113 and 114, which are arranged mirror-symmetrically to the center line M.

In the following FIGS. 5d to 5g, only the control means Si or S ₂ or S ₃ are shown, which are of interest for the respective sequence step in order to keep the representations clear. FIGS. 5c and 5i each show all control means Si or S ₂ or S ₃ visible in the respective view.

FIG. 5d shows a part of the device 100 with the fragrance cartridge 1 pivoted into an impregnation position T. The pivoting of the fragrance cartridge 1 from the basic position G shown in FIGS. 5a to 5c into the impregnation position T takes place by manually depressing the button 133, which itself here rotates about its axis of rotation D ₁₃₃ . As a result, control levers 136, which are fixedly arranged on the button 133, are moved in directions x 'and y'. The control levers 136 interact with prongs 138 of the forks 131 of the swing bridge 129 via bolts 137 and cause the swing bridge 129 to rotate in the direction of the arrow m, so that the toothed segments 130 drive the toothed wheels 113 and 114 (see FIG. 5c). With the gear wheels 113 and 114, the holder 111 with the fragrance cartridge 1 rotates 180 ° in the direction of the arrow n about the axis of rotation D, so that the fragrance cartridge 1 assumes the impregnation position T. The device 100 is now in a so-called filling position II after it has previously assumed a rest position I (see FIGS. 5a to 5c).

(See for the following description in particular Figures 5 e and 5b) During the rotation of the holder 111 with the fragrance cartridge 1 in the filling position II, the lifting fork 134 is tensioned and locked in order to hold the lifting fork 134 in a lower position L until the Bracket 111 with the fragrance cartridge 1 has turned back to the basic position G of the fragrance cartridge 1. FIG. 5e shows the lifting fork 134 in a tensioned and locked position. The following procedure is intended for tensioning and latching the lifting fork 134. The lifting fork 134 is initially in an upper position K and is rotatably mounted on the housing part 117b about an axis of rotation D _i34 (see FIG. 5b). By pressing the button 133 wiχ-d an articulated on the button

133 arranged pressure fork 139, which grips a bolt 140 arranged fixedly on the lifting fork 134, essentially moves in the direction of the arrow x 'and rotates the lifting fork

134 in an arrow direction o about its axis of rotation D _i34 . During this rotational movement about the axis of rotation D _i34 , a roller 141 rotatably mounted on the lifting fork 134 rolls on a leg 142 of a rocker 143. Here, the rocker 143 mounted on the housing part 117b rotates about an axis of rotation D _i43 in an arrow direction p about the axis of rotation Dι ₄₃ . The rocking movement of the rocker 143 in the direction of the arrow p takes place against a spring strut 144 which is mounted on the button 133 such that it can pivot about an axis of rotation D ₁₄₄ . The strut 144 consists of a bolt 145 with a slot 146. A compression spring 147 is mounted on the bolt 145. A web 148 is guided in the slot 146 and is firmly connected to a second leg 149 of the rocker 143. When the rocker 143 rotates into the. The web presses arrow direction p

148 the compression spring 147 continues to tighten and tension them. Furthermore, a clamping fork 150 (see also FIG. 5c) is suspended from the housing part 117b and can be pivoted about an axis of rotation D _1Ξ0 . The clamping fork 150 has two prongs 151 on which grippers 152 are arranged. Shortly before the button 133 is fully depressed, bolts 153, which are formed on the lifting fork 134, hit contact surfaces 154 of the grippers 152 from above and press them in the direction of the arrow y '. This is one on the tension fork

150 molded leaf spring 155 slightly biased against the pressure fork 139. This bias causes the grippers 152 catch the bolts 153 of the lifting fork 134 with a rapid movement in the direction of the arrow y as soon as the lifting fork 134 has reached its lower position L. The rapid movement of the clamping fork 150 in the direction of the arrow y is caused by the relaxation of the leaf spring 155 when the bolts 153 slide over the lugs 156 of the grippers 152. The holder 111 (not shown in FIG. 5e) now stands with the fragrance cartridge 1 in the position II shown in FIG. 5d and the impregnating body is soaked, the lifting fork being pretensioned as shown in FIG. 5e. In this position II, the button 133 is fully depressed and is either held briefly by the user or is released immediately by the user. Despite the subsequent movement of the key in the direction of the arrow x, the lifting fork 134 is held in its lower position L by the clamping fork 150 (see FIG. 5e). As a result, the rocker 143 and the shock absorber 144 are also indirectly blocked. The compression spring 147 can easily relax by lifting the button 133 to its starting position and simultaneously turning the holder 111 back with the fragrance cartridge 1 (see FIG. 5f), the compression spring 147 being partially tensioned by the web 148 which is indirectly locked via the tension fork 150 remains. That is, the energy of the compression spring 147 is partially stored. The fragrance cartridge 1, which, together with the holder 111, rotates back and forth from the impregnation position T shown in FIG. 5d to the position shown in FIG. 5f, which approximates the basic position G, strikes against the upper end of the guide element 39 Web which connects two further prongs 157 (see FIG. 5c - the web itself is covered) of the tension fork 150. As a result of this impact, the bolts 153 slide out of the grippers 152 and thus release the lifting fork 134. The clamping fork 150 rotates about its axis of rotation D ₁₅₀ . As a result of the compression spring 147 acting on the web 148, which can now release the stored energy, the rocker 143 is now rotated about its axis of rotation D ₁₄₃ in an arrow direction p 'and in turn causes one Rotation of the lifting fork 134 about its axis of rotation D ₁₃ in an arrow direction o '. Here, the lugs 135 of the lifting fork 134 lift the piston 8 on its cover 58, so that the piston 8 is raised from its first end position A to its second end position or fragrance dispensing position B (see FIGS. 5g to 5i, which shows the device 100 in one Show fragrance position III). In the fragrance position III, the compression spring 147 is now completely relaxed again (see FIG. 5g).

FIG. 5h again shows a cut-away side view of the housing 102 composed of the partial housings 117a and 117b, the device 100 being in the fragrance position III, in which the piston 8 of the fragrance cartridge 1 is in the second end position B. When the piston 8 is raised by the lugs 135 of the lifting fork 134, the cover 58 of the piston 8 interacts with the lever 120 mounted on the bridge 121 and presses its second end 128 against the force of the spring 127 in the direction of the arrow x. This causes the permanent magnet 123 arranged at the first end 122 of the lever 120 to pivot away from the sensor 124. The control electronics 126 are thus informed via the sensor 124 that the piston 8 of the fragrance cartridge 1 is in the fragrance delivery position B. Accordingly, the fan 104 can now be controlled and its air flow 110 can act on the impregnating body 21.

FIG. 5i shows an illustration of FIG. 5g from an arrow direction Vi. In this view, the two lugs 135 of the lifting fork 134 can be seen, which lift the piston 8 on its cover 58.

FIG. 5j finally shows a representation of the partial housing 117b of the device 100 corresponding to FIG. 5b. Here are the rest position I of the device 100, the upper position K of the lifting fork 134, the first end position A of the piston 8 and the basic position G of the Scent cartridge 1 reached again. The scent cartridge 1 is switched off or the piston 8 is moved from the B position to the A position by a slight depression of the button 133 (see FIGS. 5c, 5g to 5i). Here, the web arranged between the further tines 157 of the tension fork 150 presses against the guide element 39 of the fragrance cartridge 1 or the closure cap 25 and thereby pushes the cover 58 from the lugs 135 of the lifting fork 134. As soon as the cover 58 slides from the lugs 135 Piston 8 withdrawn from the spring element 17 into the container 2. This then also causes the lever 120 to spring back into the position shown in FIG. 5a, in which the permanent magnet 123 faces the sensor 124. The holder 111 rotates together with the fragrance cartridge 1 about the axis of rotation Dm slightly in the arrow direction n until the cover 58 slips off the lugs 135 and then swings back in the arrow direction n 'back to the basic position G (see in particular FIG. 5h). The gentle depression of the button 133 can be continued by a deep depression of the button 133, so that the device 100 assumes the filling position II, in which the fragrance cartridge 1 is soaked, and the process already described begins.

With regard to the control means S _x , S ₂ and S ₃ , the following is summarized for FIGS. 5a to 5j: The first control means S _x , which are responsible for lifting the piston 8, are formed by the lifting fork 134 (see, for example, FIG 5h). The holder 111 and the swing bridge 129 serve as second control means S ₂ , which are responsible for pivoting the fragrance cartridge 1 (see, for example, FIG. 5d). The third control means S ₃ , which control the first and second control means S ₂ and S ₃ , are the switching mechanism 132, which essentially comprises the key 133, the lifting fork 134, the control lever 136, the pressure fork 139, the rocker 143, the spring strut 144 and the clamping fork 150 comprises (see, for example, FIGS. 5a, 5d and 5e). FIG. 6 shows a schematic view of a further device 100, in which a fragrance cartridge 1 is arranged. First control means S are designed as electromechanical control means 158, which move an arm 159 in the arrow directions x and x 'by means of an electric motor in order to pull a piston 8 out of the fragrance cartridge 1 and push it back into the latter. The first control means Si are connected to third control means S ₃ via a control line i. The third control means S ₃ are designed as electronic control means 160, which control the first control means S _x by means of electronics. A fan 104 is also controlled by the third control means S ₃ via a control line L _v . The third control means S ₃ receive information about the position of the piston 8 from a sensor 124 via a control line L _s . When using a fragrance cartridge 1, which in principle corresponds to the fragrance cartridge described in FIGS. 2a to 2c, second control means S _{2 can be} dispensed with are, which pivot the fragrance cartridge 1 by an electronic motor serving as electromechanical control means 161. The second control means S _{2 is connected} to the third higher-level control means S ₃ via a control line S ₂ .

The invention is not restricted to the exemplary embodiments shown or described. Rather, it includes further developments of the invention within the scope of

Patent claims. In particular, the invention also provides a power supply for the fan and possibly. further electrical or electronic components via a power supply unit or batteries or accumulators and / or solar cells. According to a further embodiment variant, it is provided that the device is equipped with an extractable fan. This allows a device that can be operated without electrical energy.
