Description

The invention relates to an aerosol dispersion device according to the preamble of claim 1 and of claim 3.

As an alternative to classic tobacco cigarettes, electric cigarettes (e-cigarettes) and aerosol cigarettes are known on the market in which a liquid (“liquid”) is atomized and inhaled as an aerosol (vapor). In this respect, the consumption of e-cigarettes or aerosol cigarettes is also referred to as "vaping".

The e-cigarettes are usually electrically heated devices for vaporizing a consumable, in particular a flavored liquid (also called a liquid). Most of these devices consist of a tank, an evaporator and a battery.

With the tank systems, a distinction is made between cartomizers, drippers, clearomizers and cartridges. In the Cartomizer, the heating coil is surrounded by a non-woven material or cotton wool that serves as a liquid reservoir. Technically, a dripper is a cartomizer with a very small intake volume. The user drops the consumable directly onto the wicks, which also serve as a liquid reservoir and has to be applied again by the user after a few strokes. A clearomizer consists of a tank in which the liquid is free from the carrier material and encapsulated by the evaporator.

The systems mentioned all have in common that the user must regularly refill new consumables.

In the case of cartridge systems, cartridges filled with liquid are inserted into the e-cigarette.

The evaporation unit is used to evaporate the liquid. As a rule, no combustion process takes place in an e-cigarette vaporizer, but rather a liquid gets from a tank to an evaporation unit, which is usually designed as a heating coil, in particular through the capillary action of a wick. As soon as the user creates a negative pressure within the evaporator by inhaling, an air flow flows around the evaporation unit and the aerosol produced is inhaled by the user through the suction effect. The energy supply of the evaporation unit is usually carried out via a battery carrier equipped with rechargeable batteries or batteries. Various interfaces for connecting a battery carrier to an evaporator are known in the prior art.

Evaporators of the type mentioned at the outset are known in a large number of different embodiments.

A major disadvantage of these previously known vaporizers is, in particular, that after inhaling when exhaling, the surroundings are contaminated with residual amounts of the vaporized liquid. Another disadvantage is the use of rechargeable batteries or batteries for operating these e-cigarettes, the use of which has so far already resulted in accidents with serious health damage to users of these e-cigarettes.

EP 2 964 296 B1 shows a purely mechanical aerosol inhalation unit according to the preamble of claim 1. Here, two mutually opposite openings are formed in a suction channel or receiving line, which is used to guide air to the mouth of a user, which have mutually colliding exit directions. When such an aerosol generator is in operation, the cross section of these openings remains unchanged or constant, so that the intensity of the amount of air that flows laterally through these openings into a droplet strand propagation path does not change.

Other aerosol generators, in which only pressure vessels and no separate energy supply in the form of accumulators or batteries are used to deliver an aerosol, which may also contain nicotine, are out DE 40 30 257 A1 , EP 2 575 938 B1 or EP 2 170 280 B1 known.

The invention has for its object to provide an aerosol dispersion device in particular in the form of an inhalation unit or aerosol cigarette in the manner that mechanical atomization of a consumable or a liquid without the provision of an energy supply by means of rechargeable batteries or batteries and at the same time an adjustability the intensity with respect to the discharge of a finely dispersed aerosol.

According to the invention, the object is achieved by an aerosol dispersion device having the features of claim 1 and of claim 3. Advantageous developments of the invention are defined in the dependent claims.

An aerosol dispersion device according to the invention comprises a pressure vessel with the consumable taken up therein under pressure, the pressure vessel having a connecting piece which can be actuated to release the consumable, a mouthpiece, a nozzle element with nozzle openings which establish a first fluid connection between the mouthpiece and the connecting piece of the Form pressure vessel, the mouthpiece being arranged above and adjacent to the nozzle element in such a way that a suction channel forms with the nozzle element, at least one bypass opening which ensures a second fluid connection between the surroundings of the aerosol inhalation unit and the suction channel, and actuating means, through which an interaction with the connection piece of the aerosol can can be realized, in order to thereby open a valve of the pressure container, so that consumable contained in the pressure container is mechanically atomized as a result of the internal system pressure of the pressure container through the nozzle openings and then reaches the suction channel. Such an aerosol dispersion device further comprises means with which a free flow cross-section of the bypass opening can be adjusted from the outside in the direction of the suction channel, so that an amount of air which flows into the suction channel from the environment when the pressure container valve is open can be controlled in a controllable manner is.

In an advantageous development of the embodiment just mentioned, it can be provided that a protective cap for shielding the connecting piece or the valve is attached to an upper end face of the pressure vessel, the mouthpiece being attachable to a control element which can be connected to the protective cap in particular by inserting it.

According to a further embodiment of the invention, which is of independent importance, an aerosol dispersion device is provided for the use of a consumable with a pressure container in which the consumable is received under pressure. This aerosol dispersion device comprises a receptacle into which a pressure container with the consumable contained therein can be inserted, a mouthpiece which can be attached to the receptacle in particular by plugging in, a coupling head which can be brought into connection with a connection piece of the pressure container, and one in the coupling head Received nozzle element, in which nozzle openings are formed, which form a first fluid connection between the mouthpiece and the connector of the pressure vessel, wherein the mouthpiece is arranged on the receiving body in such a way that a suction channel forms with the nozzle element, at least one bypass opening, the one ensures second fluid connection between the environment of the aerosol cigarette and the suction channel, and actuating means through which the coupling head can be brought into interaction with the connector of the pressure vessel, thereby opening a valve of the pressure vessel, so that ent in the pressure vessel held consumable is atomized mechanically as a result of the internal system pressure of the pressure container through the nozzle openings on a side of the nozzle element opposite the receiving space and then reaches the suction channel. Also in this aerosol dispersion device, means are provided with which a free flow cross section of the bypass opening can be set from the outside in the direction of the suction channel, so that an amount of air that flows into the suction channel from the environment when the pressure vessel valve is open can be controlled is changeable.

With the aerosol dispersion device according to the invention it is achieved that through the nozzle openings of the nozzle element in combination with the internal system pressure of the pressure container, the consumable, which is accommodated in the pressure container under pressure, is mechanically atomized and thereby generated as a disperse spray. This means that the consumable or a corresponding liquid is atomized or atomized as it passes through the nozzle openings in a homogeneous or fine manner. If the aerosol dispersion device serves as an inhalation unit, the result is that the consumable or the liquid can be completely absorbed by the body when inhaled by a consumer. During the subsequent exhalation, the liquid is no longer contaminated due to the small particle sizes previously reached.

The nozzle openings in the nozzle element can expediently have a diameter of 1-5 μm and a bore length of 700 nm-50 μm.

The invention is based on the essential finding that the intensity with which a nebulized consumable is discharged from the mouthpiece can be regulated by the means for adjusting the free flow cross section of the bypass opening. In other words, these means for adjusting or changing the free flow cross section can regulate the amount of air that is discharged into the environment from the mouthpiece in connection with the aerosol that has already been atomized, to a certain value.

At this point, it is pointed out separately that “dispersion device” in the sense of the present invention relates to a device with which a specific discharge or release (= fine distribution) of a nebulized consumable or liquid into the environment is possible with a certain intensity. In general, the feature “mouthpiece” here means a component from which the aerosol which has already been atomized, together with a certain amount of air which has flowed in through the at least one adjustable bypass opening, is then discharged together to the surroundings.

If the dispersion device according to the invention is used by an user as an inhalation unit, preferably as an aerosol cigarette, the mouthpiece serves to be received directly in the mouth or throat / lungs of the user in order to discharge the atomized aerosol with the desired or to achieve the set intensity.

According to an advantageous development of the invention, a central opening can be formed in an upper end face of the control element or of the receiving body in a central region, which opening is surrounded by a substantially closed annular flange. Here, the bypass opening can be formed in the upper end face of the control element or the receiving body adjacent to the central opening, the mouthpiece having at least one through opening in its lateral wall, preferably adjacent to its lower edge, and being rotatably received within the annular flange . As a result, the means for adjusting the free flow cross section of the bypass openings are formed by a rotatability of the mouthpiece within or relative to the flange. When the mouthpiece is rotated within the annular flange, the opening formed in the wall of the mouthpiece can be at least partially overlapped with the bypass opening, as a result of which the free flow cross section of the bypass opening is set for targeted opening or closing. In other words, the amount of air that flows into the already atomized liquid from the outside, and thus the intensity during “steaming”, can be easily achieved simply by rotating the mouthpiece within the annular flange.

In an advantageous development of the invention, the actuating means are formed by a lever device which can be pivoted about a joint and which has a cam region on which a bottom surface of the pressure vessel is seated. When the lever device is pivoted about the joint, a pressure container inserted into the receiving body is axially displaced along its longitudinal axis in such a way that a valve of the pressure container opens.

In an advantageous development of the last-mentioned embodiment, the lever device has a preferably latchable button for locking the lever device against pivoting around the joint in order to prevent undesired actuation of the connection piece of the pressure vessel. A holding lug is preferably provided on the lever device, which can hold the lever device in a non-activated position.

According to an advantageous development of the invention, the coupling head, in which the nozzle element is accommodated, can be supported on the end face on a support area of the support body. This enables the coupling head to be securely seated on or in the support body as a result of the targeted derivation of the forces acting on the coupling head on the support body.

In an advantageous development of the invention, the nozzle element in which the nozzle openings are formed can be replaced. Such replacement is for the purpose of inserting a new nozzle element if the nozzle openings of the previously used nozzle element become clogged and / or dirty as a result of frequent use, or for the purpose of using a nozzle element whose nozzle openings have a different cross section and / or have a changed number of nozzle openings in order, for example, to achieve a changed delivery amount of the aerosol inhalation unit according to the invention when “inhaling”. In the same way, even when the aerosol dispersion device according to the invention is used or used in the technical or cosmetic field, by exchanging the nozzle element it is achieved that, depending on the respective application, there are always nozzle openings with a diameter adapted to this.

In an advantageous development of the invention, the pressure vessel can be designed as an aerosol can, and preferably as a two-chamber can, the pressure vessel being filled with a pressure range between 2 and 26 bar.

In an advantageous development of the invention, the aerosol dispersion device can be used or used as an inhalation unit. In this case the consumable in the pressure container e.g. in the form of nicotine-containing liquid. Accordingly, the aerosol inhalation unit according to the invention then serves as an aerosol cigarette when releasing the nicotine-containing liquid, and without the need for a separate energy supply in the form of rechargeable batteries or batteries, because the liquid is atomized solely by the system pressure of the pressure container.

The same features in the drawing are provided with the same reference numerals. At this point, it is pointed out separately that the drawing is only simplified and in particular is shown without a scale.

The aerosol dispersion device according to the invention 1 , 100 can be used as an inhalation unit, an associated mouthpiece being used to discharge or introduce a finely nebulized aerosol directly into the mouth or throat of a user in a desired or set intensity.

The consumable can be a liquid that contains nicotine and / or other flavorings.

In view of the fact that the consumable contained in the pressure container can be formed from a liquid with portions of nicotine, the aerosol dispersion device according to the invention, in its function as an aerosol inhalation unit, is also referred to below as an “aerosol cigarette” without it a restriction should only be understood to mean the use of a liquid that contains nicotine.

In the shown embodiments of the aerosol inhalation unit 1 , 100 comes a pressure vessel in the form of an aerosol can 4th used, which is a disposable item. After consumption, the aerosol can 4th can be easily replaced or replaced with a new can.

In the embodiment according to the 1-9 can an aerosol can 4th can be used in a hand control device which has a mouthpiece. By actuating a swiveling lever a valve of the aerosol can 4th specifically opened to allow it to be in the aerosol can 4th release targeted liquid under pressure for "evaporation" or nebulization.

In the embodiment according to the 10-12 is on an upper face of an aerosol can 4th attached a protective cap into which a cigarette head element having a mouthpiece can be inserted. By exerting an axial pressure on the cigarette head element, the valve of the aerosol can 4th specifically opened to allow it to be in the aerosol can 4th release targeted liquid under pressure for nebulization.

• Die in 1 bis 9 dargestellte Aerosol-Zigarette 1 umfasst vorzugsweise einen Aufnahmekörper 3 mit einem Aufnahmeraum (vgl. 4), in den eine Aerosoldose 4 (vgl. 4) eingesetzt werden kann. Insoweit kommt diesem Aufnahmekörper 3 die Funktion der vorstehend genannten Handbedienungseinrichtung zu. In bekannter Weise trägt eine solche Aerosoldose 4 ein Verbindungsstück 16 (vgl. 6), das in axialer Richtung verschieblich ist, um ein (nicht gezeigtes) Ventil der Aerosoldose 4 zu öffnen.

Details of the two shown embodiments of the aerosol inhalation unit according to the invention are explained in detail below:

• In the 1 to 9 illustrated aerosol cigarette 1 preferably comprises a receiving body 3rd with a recording room (cf. 4th ) in which an aerosol can 4th (see. 4th ) can be used. In this respect comes this body 3rd the function of the above-mentioned manual control device. Such an aerosol can carries in a known manner 4th a connector 16 (see. 6 ), which is displaceable in the axial direction, around a valve (not shown) of the aerosol can 4th to open.

For example, a summary of the 1-3 at clearly that an optionally lockable lever 5 to operate the connector 16 the aerosol can 4th about a joint 9 with the receiving body 3rd connected is. As a possible embodiment, the lever carries 5 a sliding or swiveling and preferably latchable button 6 whose nose 7 the lever 5 to activate the aerosol can 4th can lock.

A mouthpiece 2nd is so on the receiving body 3rd arranged that there is a suction channel 24th ( 8th ) with the nozzle element 17th trains.

In the receiving body 3rd is in a central area from the top end 30th a central opening 14 formed by an annular flange 31 is enclosed. In the upper face 30th of the receiving body 3rd are adjacent to the opening 14 Bypass openings 10th trained, for example in the view of 4th are recognizable.

The mouthpiece 2nd has at least one through opening or recess in its lateral wall 15 on. In addition to the 6 is the mouthpiece 2nd in the 6a shown again in a simplified perspective view, which makes it clear that the recess 15 is formed in a wall of the mouthpiece adjacent to its lower edge. Preferably at the bottom of the mouthpiece 2nd two such recesses 15 trained, which are opposite to each other.

For connecting the mouthpiece 2nd with the receiving body 3rd can the mouthpiece 2nd in the annular flange 31 to be inserted, with the mouthpiece 2nd inside the annular flange 31 or within the opening 14 can be held, for example, by latching. In any case, the aerosol cigarette is in a state of use 1 the mouthpiece 2nd rotatable within the annular flange 31 or the opening 14 is included.

When turning the mouthpiece 2nd inside the annular flange 31 get the recesses 15 of the mouthpiece in interaction with the associated bypass openings 10th . It is therefore possible that the bypass openings 10th by turning the mouthpiece 2nd inside the annular flange 31 be opened or closed in a targeted manner, depending on the angular position or positioning of the mouthpiece 2nd with its recesses 15 inside the flange 31 . Depending on the extent to which the bypass openings 10th either from the edge area of the mouthpiece resting on it 2nd closed or thanks to the recesses 15 that face the bypass openings 10th can reach, are open, air from the environment U (cf. 5 , 6 ) the aerosol cigarette 1 in the suction channel 24th flow in. This allows a user to simply twist the mouthpiece 2nd relative to the flange 31 the suction power on the aerosol cigarette 1 or individually adjust the intensity of the inhaled aerosol to his needs.

The aerosol cigarette 1 includes a coupling head 8th that on the connector 16 an aerosol can 4th can be put on. In the coupling head 8th is a nozzle element 17th added in which a plurality of fine nozzle openings 25th (see. 9 ) are trained. A positioning of the coupling head 8th when he clicks on the connector 16 put on and in it the nozzle element 17th is used, for example, based on the 5-8 evident.

At this point it is pointed out separately that according to an alternative embodiment (not shown) the bypass openings 10th also directly on the coupling head 8th can be arranged or formed.

4th shows the recording body 3rd without inserted aerosol can 4th . To align the coupling head 8th when inserting the aerosol can 4th in the receiving body 3rd is a stop in a preferred embodiment 22 on the receiving body 3rd . The lever 5 preferably also has an area 28 on when activating the aerosol can 4th the coupling head 8th aligns. The lever 5 and / or the receiving body 3rd point as a possible embodiment in the area of the joint 9 cam 20th on that are used as standing aids to the aerosol cigarette 1 to be able to stand upright.

The coupling head 8th can be on the face of the receiving body when inserted 3rd in the area 23 support.

To activate the aerosol can 4th carries the lever 5 a cam area 21st swiveling around the joint 9 . Preferably located on the lever 5 a nose 11 that are on the receiving body 3rd can support so that the lever 5 is held in its closed, non-activated position, as in 5 shown. When operating the lever 5 the lever turns 5 around the joint 9 , causing the cam area 21st the aerosol can 4th axially shifts so that the connector 16 by means of the coupling head 8th who is in the field 23 of the receiving body 3rd is supported, pressed and the valve (not shown) of the aerosol can 4th opens and the liquid, not shown, which is inside the aerosol can 4th is through the nozzle element 17th is nebulized.

The aerosol can 4th is known as the one-chamber or two-chamber system from the Aerosol technology implemented as a tank system to hold the liquid.

Preferably the aerosol can 4th as a two-chamber system, best known in the aerosol sector as the BagOnValve system. Alternatively, all known valve types, whether male or female or tilting valve or 360 ° valve, can also be used.

The nozzle element 17th has the smallest openings 25th on, one of which in the 9 is shown. In the representation of 9 with the reference symbol “26” is a supply bore inside the nozzle element 17th shown in a smallest opening 25th flows. Ideally, the openings should 25th a diameter of about 2 µm and a bore length 27 from about 700nm to 50 µm.

The liquid is in the aerosol can 4th pressurized, causing the liquid to actuate the connector 16 through the nozzle element 17th or its nozzle openings 25th is pressed. This causes the liquid jet to decay as a disperse spray.

As from the 9 further visible is the diameter for this supply hole 26 larger than that of the smallest opening 25th , so that too much backflow or flow resistance within the nozzle element for the liquid 17th is prevented.

The pressure with which the liquid, not shown, in the aerosol can 4th should preferably be applied, should be between 16 to 22 bar. Optionally, the pressure in the aerosol can 4th can also be up to 26 bar. This pressure causes the aerosol can to open 4th and a corresponding leakage of the liquid in the suction channel 24th can form a disperse spray. However, all other known nozzle shapes from mechanical process engineering, such as the double jet nozzle, hollow cone nozzle, swirl nozzle etc. can also be used.

As already explained above, the nozzle element 17th preferably in the coupling head 8th recorded and can also, as not shown, be provided axially and / or radially with sealing elements and / or with filters. In the example shown, the nozzle element is sealed 17th by means of a seal 19th that creates a radial and / or axial seal and between the coupling head 8th , the nozzle element 17th and a retaining ring 18th is arranged.

In the 10-12 is a second embodiment for the aerosol dispersion device according to the invention 100 shown, which is preferably used as an inhalation unit. The basis for this embodiment is a disposable container in the form of an aerosol can 4th , which is filled with a liquid under pressure, which can contain nicotine.

In the second embodiment, the aerosol can is on an upper end face 4th is a protective cap 101 attached. Here, the aerosol can is in a non-use state 4th an upper opening 103 the protective cap 101 through a seal 102 locked. The valve (not shown) of the aerosol can is correspondingly 4th with the protective cap closed 101 and intact seal 102 effectively protected against external influences.

In the representation of 11 is indicated in the right picture by the arrow that the seal 102 from the protective cap 101 can be deducted. As a result, as shown in representations a and b of 12 you can see the opening 103 exposed at the top of the protective cap 101 is trained.

In the embodiment according to the 10-12 comprises the aerosol dispersion device 100 a control 104 on which a mouthpiece 2nd is appropriate. In the same way as in the first embodiment, the second embodiment also has a coupling head 8th on, in which a nozzle element (with fine nozzle openings) is received. But it can also in this embodiment 10-12 alternatively all known valve types, whether male or female or tilting valve or 360 ° valve are used.

If the aerosol dispersion device 100 according to the 10-12 The control element comes as an inhalation unit and in this case preferably as an aerosol cigarette (if the liquid to be atomized contains nicotine) 104 the function of a cigarette head element. For the following explanation, only the term “cigarette head element” is used for the control element, without any restriction being seen here.

The sequence of representations a to f of 12 clarifies that after the top opening 103 the protective cap 101 the coupling head has been exposed 8th from below into the cigarette head element 104 is used, then the cigarette head element 104 in connection with the coupling head 8th and the nozzle element received therein from above into the opening 103 is used. If the cigarette head element 104 completely into the opening 103 the protective cap 101 the coupling head is seated 8th on the connector 16 the aerosol can 4th on.

If the valve of the aerosol can 4th is of the "female" type (not shown in the drawing), the coupling head 8th by means of a connecting piece 16 in a one-piece or multi-piece design are inserted into the receptacle (not shown) of the female valve for actuating the female valve.

Inside the opening 103 can the cigarette head element used therein 104 by turning it about its longitudinal axis and simultaneously pressing it down into an operating position in the 12f (far right in the picture) is shown. This operating position also corresponds to the representation in 10th . Starting from this operating position, the cigarette head element 104 by axially pressing or moving downwards, ie in the direction of the aerosol can 4th (as in 12f indicated by the arrow V), so that the connecting piece 16 the aerosol can 4th as a result of exposure to the coupling element 8th is also pressed down and thus the valve of the aerosol can 4th opened to release the liquid. For this purpose is on the side of the cigarette head element 104 a control surface is formed or formed, which a user can operate with his thumb, for example.

After in the second embodiment according to the 10-12 the valve of the aerosol can 4th by axially pressing or moving the cigarette head element 104 has been opened downwards, the liquid is atomized, which is in the aerosol can 4th is received under pressure through the nozzle openings of the nozzle element 17th and thus in the same way as in the first embodiment according to 1-9 which may be referred to to avoid repetitions.

In the second embodiment according to 10-12 For example, an intensity with which a finely dispersed aerosol is discharged from the mouthpiece can be adjusted or regulated in the same manner as in the first embodiment. This means that even in the second embodiment, a first fluid connection between the nozzle element, which is in the coupling element 8th is included, and the connector 16 the aerosol can 4th consists. The mouthpiece 2nd is so on the cigarette head element 104 attached and thus arranged adjacent to the nozzle element that a suction channel forms with the nozzle element. The aforementioned adjustability of the intensity or air quantity is ensured by the fact that at least one bypass opening is also provided in the second embodiment, which has a second fluid connection between the environment U of the aerosol inhalation unit 100 and forms the suction channel. As already explained in connection with the first embodiment, an intensity can then be applied in relation to the application of a finely dispersed aerosol from the mouthpiece 2nd in a simple manner by rotating the mouthpiece within the associated receptacle of the cigarette head element 104 can be achieved.

According to the second embodiment as well 10-12 it is possible to replace the nozzle element. In view of the fact that the nozzle element as explained in the coupling head 8th can be replaced, a replacement of the nozzle element in a simple manner by replacing the coupling head 8th respectively.
