Vaporizer device for an electric inhaler

description

The invention relates to an evaporation device for an electric Inhala tor, in particular in the form of a smoking device and an electric inhaler, in particular in the form of a smoking device, with an evaporation device and a method for producing an evaporation device and a cartridge for an inhaler.

Most of the evaporation devices currently on the market are implemented as an evaporation unit in an electrical or electronic cigarette product and work according to the so-called wick-coil principle. A fibrous wick is at least partially wrapped with a heating coil and is in fluid communication with a liquid or liquid storage device. As a result, the wick sucks up liquid or liquid from the liquid reservoir. When the heating coil is heated, some of the liquid in the wick evaporates in the area of the heating coil. To produce an inhalable aerosol, the liquid contains one or more substances suitable for this. The mixture of substances forms a formulation. A formulation in the case of an electric smoke product from the tobacco processing industry is, for example, the liquid composed of various components. A formulation in the case of an inhalable medicament or medical article is a combination of one or more active substances and one or more carrier substances. For a choice between different taste union effects, liquid storage with different substances are available on the market, from which the consumer can select a liquid storage with a preferred substance, which is inserted into the electronic cigarette product before use. From DE 10 2017 1 19 521 A1 a vaporizing device for an electrical inhaler is known, which has an electronic control device and at least one heating element for vaporizing liquid supplied from a liquid reservoir. The vaporized liquid is taken up by a stream of air flowing through the vaporization device. The electronic control device is designed to heat the at least one heating element with a variable control frequency.

WO 2018/050720 A1 proposes a flavor container for electrical smoking devices such as in particular electronic cigarettes or "heat-not-burn" smoking articles, which is filled with fiber material and contains a crushable or breakable capsule, the content of which is a liquid or can be a liquid or a gel.

WO 2014/066730 A1 discloses an electronic cigarette in which the heating device can be designed as a removable cartridge or cassette.

WO 2015/144822 A1 suggests designing the liquid storage device for an electric smoking device as a sleeve-shaped reservoir.

WO 2014/088889 A1 describes an electronic cigarette with a screw-on reservoir in which there is an evaporator whose construction is based on the wick-coil principle.

WO 2014/037794 A2 shows an electronic smoking device that has one or more micro heaters that are in direct fluid contact with an aerosol substrate, the number of micro heaters and also the shape of the aerosol substrate being able to vary.

EP 3 078 281 A1 discloses an electric smoking device with a housing which contains one or more woven fiber tubes and a liquid supply. At least one of the woven fiber tubes has an electrically conductive heating section, the first side of which is connected to a first electrical contact or a first electrical line and the second side of which is connected to a second electrical contact or a second electrical line. Further a fluid supply is provided which is in fluid contact with one or more end portions of the woven fiber tube.

DE 10 2016 120 803 A1 discloses an evaporator element to be used in an evaporation device for an electric inhaler, in particular in the form of a smoking device, which evaporator element has an inlet side, an outlet side and, in particular, a platelet-shaped substrate and a plurality of microchannels and a Contains resistance heating element for vaporizing liquid conveyed through the microchannels, the microchannels each extending from the inlet side to the outlet side through the substrate, the substrate being electrically conductive and the resistance heating element being formed by the substrate.

The object of the present invention is to improve an electric inhaler system and to specify a separable and integrable vaporizer device and types of electric inhalers which, in one embodiment, allow the separate evaporation device to be used and in which the evaporation device is integrated in another embodiment to specify a consumable article suitable for this purpose for inhalation, in particular in the form of a cartridge.

It is an object of the present invention to improve an evaporation device for an electric inhaler in various respects, in particular to enable flexible use in different types of electric inhalers and in different ways, to realize a smaller installation space and to increase the evaporator output, and to provide a simple, reliable and reproducible vaporizer device which is able to generate an amount of vapor with desired properties such as amount and composition, and in which a reliable active ingredient administration of a formulation is thus given. It is also an object to provide standardized components for an inhaler, which can be inexpensively steep and can be integrated into an inhaler or Inhalatorbe components by simply joining them together, and appropriate manufacturing processes are indicated. This object is achieved according to a first aspect of the present invention with an evaporation device for an electric inhaler, with a housing having an outside, an air passage channel formed inside the housing, which has an air inlet opening and an air outlet opening, with at least one evaporator element, which has a supply side , has a delivery side and a heating device, is fluid-permeable from the supply side to the delivery side and is arranged on or in the housing so that its delivery side is in fluid communication with the air passage channel, with at least one fluid inlet opening provided on the outside of the housing and at least one fluid connection line formed within the housing, which extends from the at least one fluid inlet opening to the supply side of the evaporator element.

In this way, an improved vaporization device is provided. According to the invention, the housing of the evaporation device contains not only at least one evaporator element, but also at least one fluid connection line to supply the evaporator element with liquid. The liquid can have one or more substances for producing a taste effect or a medication. With the aid of the invention, a small installation space can be realized, which is made possible in particular by the use of a fluid-permeable evaporator element. Furthermore, according to the invention, the fluid-permeable vaporizer element is arranged on or in the housing in such a way that its delivery side is in fluid communication with the air passage channel, a reliable and at the same time particularly effective drug administration can be realized. By integrating at least one evaporator element and at least one fluid connection line, the evaporation device forms an evaporator unit, which can preferably be designed in the manner of a capsule or cartridge. The evaporation device is equally suitable for one-way use as well as for reusable use. The evaporation device can be designed in such a miniaturized manner that it is in the manner of a flavor capsule in sections of a continuously formed strand with fiber material and / or segments or a rod made up of segments. can be laid. Individual segments that contain one or more intermediate products of a consumable item can be separated from the strand. The evaporation device can be designed so as to be self-sufficient that it contains an electrically activatable heating device to which only an energy source, in particular a current source, has to be applied. He allows a high production speed for a consumable article with an evaporation device. In order to connect the electrical contacts of the evaporation device, it has to be arranged so as to be oriented in accordance with the design of the electrical contacts of the inhaler or inhalation device.

It is also an object of the present invention to provide an improved inhaler with a vaporizer element.

This object is achieved by an electric inhaler with a Grundkör which contains a source of electrical energy and has a holding end and a receiving end spaced apart from the holding end and a preferably hollow shaft for releasably receiving a consumable article in the form of a smoking article or a Medical article forms, and with at least one vaporization device, preferably according to one of claims 1-15 or the embodiments 1 -36, which has a housing and which is detachably connected to its housing on the shaft or stationary on the shaft and firmly connected to the shaft, in particular below Formation of an electrical contact to the energy source, arranged or positionable. The evaporation device is preferably connected to its housing in a stationary manner on the shaft and firmly connected to the shaft that the shaft integrally forms the housing and is provided with lines for connecting the evaporation device to the electrical energy source.

This object is also achieved by an inhaler with a base body in which an energy source, preferably a power source, and in which a control unit are accommodated, preferably exchangeable, and in which the base body has a holding end and a receiving end arranged opposite the holding end , for the detachable inclusion of a consumable article in the form of a smoking article or a medical article, and on which one is Shaft protruding from the main body is formed, the inhaler being characterized by a passage channel extending inside the shaft with an air inlet opening and an air outlet opening and at least one, preferably flat, evaporator element, the one, preferably planar, delivery side and one supply side and is received on a wall in the passage channel and is aligned with the delivery side to the longitudinal extension of the passage channel parallel or inclined to form a free air cross-section and a plurality of heating channels arranged transversely to the longitudinal extension of the, preferably flat, evaporator element, the shaft is provided with fluid connection lines, which extend from the supply side of the, preferably flat, evaporator element in the direction of, preferably up to the, surface of the outside of the shaft.

The shaft is preferably designed and configured to receive a consumable article in the form of a smoking article or a medical article by means of an internal centering device. The shaft preferably has a wall. The United evaporator element is preferably aufgenom men on and / or in the wall of the shaft. In order to accommodate the evaporator element, the wall can be largely flat in some areas. The evaporator element can protrude beyond the wall into the passage channel, largely flush with the wall, or be set back into the wall. The fluid connection lines are preferably formed in the wall of the shaft or guided through the wall of the shaft. Electrical lines are provided in the wall of the shaft or along the wall of the shaft for connecting the evaporation element or the heating device to the energy source, preferably the power source. A recess Z1 can be seen in the wall of the shaft or housing. A separate insert part, in which the fluid connection lines are arranged, can be accommodated in the recess Z1. A recess Z2 can be provided in the wall of the shaft or the housing. The evaporator element can be accommodated in the recess Z2. The recess Z1 and the recess Z2 can both be arranged one behind the other in a region of the wall of the shaft or the housing and in the direction of the passage channel. The recess Z1 and the recess Z2 can both be arranged one behind the other in a region of the wall of the shaft or of the housing, forming a stepped insertion and receiving opening. The recess Z1 can be dimensioned such that the separate insert part is received in a preferably light press fit. The recess Z2 can be dimensioned such that the evaporator element is received in a preferably light press fit.

Preferred embodiments and developments of the invention are specified in the dependent claims and the exemplary embodiments.

The evaporator element is preferably located with its delivery side in direct fluid communication with the air passage, so that the delivery side is arranged pointing into the interior of the air passage and / or is located in or adjacent to the air passage, in particular leaving a free passage cross-section and / or in particular without reaching through or closing the air passage. Such an order is particularly advantageous for achieving a particularly compact construction and for a particularly effective administration of active ingredients. It allows simple manufacture.

Furthermore, the discharge side of the evaporator element is essentially planar and oriented essentially parallel or inclined to the longitudinal extension of the air passage with the formation of a free air passage cross-section in the air passage, with the vaporizer element in particular having a substantially flat or flat body of preferably qua deral Has shape. Such an arrangement is also particularly advantageous for reducing the installation space, in particular if the evaporator element is relatively thin. Furthermore, the essentially planar design of the delivery side of the evaporator element ensures a particularly effective introduction of the vaporized liquid into the air passage, especially if the housing contains a plurality of fluid connection lines that open into the delivery side of the evaporator element. The planar design allows the evaporator element to be manufactured from appropriately processed wafers, with several hundred to several thousand evaporator elements being able to be obtained from one wafer. To influence the mixing of the evaporated liquid with the air, the air passage channel can have a change in cross section, in particular a narrowing or widening of the cross section, for example at the point or in the area of the evaporator element or at a point or area adjacent to the evaporator element. The constriction or the widening of the cross section of the air passage can be designed in a discontinuously changing shape or in a continuously changing shape.

In a further preferred embodiment, the delivery side of the at least one evaporator element is oriented towards the air passage in such a way that the fluid emerging from the delivery side of the at least one vaporizer element is essentially miscible in a cross-flow with air guided through the air passage. Such an arrangement leads to a particularly effekti ven intermixing of the evaporated liquid emerging from the delivery side of the evaporator element with the air guided through the air passage channel.

The heating device of the evaporator element preferably has at least one heating channel with a longitudinal axis, which is oriented with its longitudinal axis at least in sections essentially transversely or inclined to the delivery side of the evaporator element. The heating device of the evaporator element can have a plurality of heating channels with a respective longitudinal axis, which are oriented with their respective longitudinal axis, at least in sections, essentially transversely or inclined to the discharge side of the evaporator element.

The evaporator element can preferably be designed as a flat body which has an inlet side, an outlet side and a preferably cuboid substrate. The inlet side can correspond to the supply side and the outlet side can correspond to the delivery side. The fluid permeability of the evaporator element is preferably produced by a plurality of microchannels, preferably arranged in parallel, which extend through the substrate from the inlet side to the outlet side. A microchannel - or, in the case of a plurality of microchannels, each microchannel of a predominant part of the microchannels - can form a wall along its longitudinal extension or along its longitudinal axis which is transverse to the Longitudinal extent or transversely to the longitudinal axis of the microchannel closed umlau fend is formed. The wall can be essentially cylindrical and / or conically shaped. The wall of the microchannel can extend from the inlet side to the outlet side of the substrate. A formation of a microchannel with this wall is far superior to all known heating systems. Neither wick / spiral systems, nor heatable fiber fabrics or heating grids made of wire filaments are able to provide such large and effective heating and evaporation surfaces. The known constructions of heating systems are not able to sufficiently convert the heating energy used into an evaporation of liquid. You have to work with heating temperatures well above the actual evaporation temperatures, which increases the risk of the production of pollutants. With the proposed heating device, however, optimal evaporation results can be achieved at already relatively low temperatures. The heating device proposed in the present invention is preferably free of a helically constructed heating element which surrounds a wick. The heating device proposed in the present invention is preferably free of a fabric-like or fiber-like heating element in which the outer surfaces of electrically heatable filaments or wires are provided for vaporization. The substrate can form a substantially rectangular delivery side, with an edge length K1 and an edge length K2, wherein K1 can be equal to or greater than K2. K1 can be about 1 to 5 mm, K2 can be about 1 to 5 mm. K2 can for example be in the range of 2 mm +/- 0.5 mm and K1 for example in the range of 3 mm +/- 0.5 mm. The number of microchannels along the direction of edge length K2 is preferably greater than or equal to 8 and / or preferably less than or equal to 30. The number of microchannels along the direction of edge length K1 is preferably greater than or equal to 12 and / or preferably less than or equal to 45. A microchannel has or several microchannels each have an inner boundary surface. The inner boundary surface is preferably designed as a closed circumferential wall, preferably with an essentially cylindrical or conical or polygonal shape. The inside diameter of the microchannels can be between 5 and 100 μm, preferably between 20 and 100 μm, particularly preferably between 25 and 80 gm. The length of the micro-channels can be 100 to 800 gm, preferably 150 to 500 gm, particularly preferably 180 to 450 gm. With these values for the inside diameter of the microchannels, a capillary effect can advantageously be ensured. Thus, on the supply side or on the inlet side of the microchannel, liquid penetrating into a microchannel can reliably flow almost automatically through the microchannel to the delivery side or the outlet side of the microchannel until the microchannel is filled with liquid. Several microchannels can be arranged in the substrate. Walls made of the material of the substrate can be formed between the microchannels. The substrate is preferably designed to be electrically conductive itself. The material of the substrate can be silicon, doped silicon, doped ceramic, metal-ceramic, filter ceramic, semiconductor material, in particular ger manium, graphite, semi-metal and / or metal, or contain these substances or combinations of these substances. Particularly preferred is a material for the substrate that is essentially metal-free, at least at the contact points of the substrate with a fluid to be evaporated, in particular in the form of liquid, in particular at least on the inner walls of a microchannel or the microchannels. The substrate can take on the function of a resistance heating element. The wall thickness between two microchannels can be between 15 and 400 μm, preferably between 30 and 350 μm. If the wall thickness is in this range, the substrate can be heated very quickly for evaporation. This wall thickness also favors rapid cooling. In a certain way, the thermal inertia of the heating device is reduced to a minimum, which enables precise control of the evaporation and helps to avoid prolonged temperature increases until an evaporation temperature or decreases to an initial temperature before an electrical voltage is applied. In this way, difficult-to-control intermediate phases in the form of temperature increases and decreases can be significantly shortened or largely avoided. Evaporation steps can be started and canceled suddenly. With a pulsed control in the form of switching the power supply to the substrate on and off with a suitable control frequency, a delay-free and complete evaporation of a microchannel filling can be guaranteed within a very short time. The control frequency can be in the Hz or kHz range and between 1 Hz and 50 kHz, preferably between 30 Hz and 30 kHz, particularly preferably between 100 Hz and 25 kHz. In another embodiment, the control frequency can be in the range between 5 Hz and 50 Hz, preferably between 10 Hz and 40 Hz.

In one configuration, the substrate can be designed as a porous body. The aforementioned heating channels can be provided for the passage of a liquid or gaseous heating medium. In a modification, the heating channels are provided for receiving electrical resistance heating wires or a heatable lining, preferably in the form of an inner coating.

In a further preferred embodiment, the housing is divided into at least two housing parts arranged one behind the other in the direction of the orientation of the air passage and / or transversely to the orientation of the air passage, which preferably extend in the direction of the orientation of the air passage and / or are detachably connected to one another. For example, the housing parts can form two cap-shaped or capsule-shaped hollow bodies lying one behind the other in the direction of the air passage channel, which in particular can be positioned, preferably plugged together, overlapping one another. In a modification to this or in addition, the housing parts can, for example, form two half-shells arranged next to one another transversely to the orientation of the air passage and thereby form a base part and a cover part, so to speak. Especially in the latter embodiment, it is particularly advantageous for the production of the Verdampfungsvor direction to connect the two housing parts with a hinge ge articulated, which makes the United evaporator element easier to assemble from the air passage in the open state, while the two housing parts in the closed state then form the finished housing and are then preferably also non-releasably locked to one another, for example by gluing or a tongue and groove connection or a click connection to one another. In one embodiment, the housing is designed to be divided with a base part and a cover part. The bottom part can be formed half-shell-shaped and can have a bottom part edge. The cover part can be designed in the shape of a half-shell and can have a cover part edge aufwei sen. The base part edge and the cover part edge can have mutually complementary elevations and / or depressions, so that when add cover part and base part, elevations and depressions interlock and cover part and base part are fixed to one another and connected to one another. In a further embodiment, the base part edge and the cover part edge can be largely flat, so that when the cover part and base part are joined together, the base part edge and the cover part edge lie flat against each other and can be connected to one another, preferably by a connection means such as an adhesive, welding in the form of thermal welding, ultrasonic welding, or pressing or combinations thereof.

The housing provided as a hollow body due to the formation of an air passage can basically have different cross-sectional shapes, for example a round, elliptical, polygonal, square or rectangular cross-section and / or a symmetrical or asymmetrical cross-sectional shape.

In a further preferred embodiment, a liquid reservoir is arranged at least on a section of the outside of the housing, which is in fluid communication with the at least one fluid inlet opening or the plurality of fluid inlet openings. With the arrangement of a liquid reservoir on the outside of the housing, not only a particularly compact design, but also a simple fluid connection of the liquid reservoir with the at least one fluid inlet opening or the multiple fluid inlet openings on the outside of the housing can be achieved. It is therefore particularly expedient in a further development of this embodiment to arrange the liquid reservoir on the outside of the housing at least in the area of the fluid inlet opening (s), which creates a direct fluid connection without the need for additional connecting lines.

The liquid reservoir can for example be designed as a double-walled sleeve with an annular cavity in which the fluid to be vaporized is stored. The cavity can be partially or completely filled with a layer containing fiber material in which the fluid to be evaporated is stored in the interstices between the fibers. The liquid storage device can have an outer casing which is liquid-tight. The liquid reservoir can have an outer covering and can be free of an inner covering and can be filled with a layer surrounded by the outer covering and containing fiber material in which the fluid to be vaporized is stored in the spaces between the fibers.

The liquid reservoir can be free of an outer covering and can be free of an inner covering and can be designed as an inherently stable layer which contains fiber material in which the fluid to be evaporated is stored in the spaces between the fibers. The fiber material can be consolidated in such a way that it is designed to be inherently stable, for example in the manner of a sheath-free fiber tube.

The liquid reservoir can for example be designed as a double-walled sleeve with a ring-shaped cavity storing the fluid to be vaporized, in which sleeve the vaporizer element is taken up on and / or in the inner wall.

In a particularly preferred embodiment, the liquid reservoir has at least one layer that surrounds the housing at least in sections and preferably rests against the outside of the housing in a play-free or pretensioned manner at least in sections. The layer can be designed in such a way that the layer rests, at least in sections, linearly and / or flat only on a part or also completely with its inside on the outside of the housing.

The liquid reservoir can preferably be designed as a jacket tank, which can be slipped over the housing in an essentially form-fitting manner. In the cavity enclosed by an inside of the liquid reservoir, a cartridge can be inserted and positioned, for example, in which the evaporation element is arranged. In the formation of the liquid reservoir with egg ner layer, the layer can have the shape of a tube.

In one embodiment it can be provided that the layer surrounds the housing in sections in its circumferential direction. In this case, the layer is not designed as a closed tube. The position is as a curved position around the housing to form a circumferential direction of the housing at a Positioning the position-forming free space designed. The cross-section of the layer has a C-shape and is therefore designed to be quasi-open. In the C-shape, the layer can be machined to produce a C-shape contour and bulged to preserve the C-shape contour and be designed to be slightly expandable against a restoring force, so that it is arranged around the housing with automatic clamping engagement can be or is. For this purpose, the inner contour of the C-shape can have a certain undersize in relation to the outer contour of the housing.

The layer is preferably biased against its seat on the outside of the housing. For this purpose, the layer can be provided with an undersize in relation to its seat on the housing and the cross section of the housing on the seat of the layer.

Instead of or in addition to a curved or curved layer pre-assembled in the form, a folded layer can also be provided.

The layer can contain fiber material, for example in the form of filaments or paper fibers, and be designed to be compressible. In this embodiment, the edge area of the layer that comes to rest adjacent to the housing or adjacent to the receiving area of the layer in the case of a shaft integrating the housing (as will be described later) can be compressed in a targeted manner. With such a compression or compression, the free spaces between see the fibers in the edge area are reduced, whereby finer, narrower För derkanäle for the stored fluid to be evaporated can be formed, which a fluid transport from the other areas of the situation with larger Förderka channels in the direction favor the fluid connection lines of the housing. In a certain way, the capillary delivery effect can thus be optimized as required. If, for example, the layer is withdrawn from the housing or the shaft, the free spaces between the fibers on the inside of the layer widen again, after which a cross-sectional reduction that drives the capillary conveyance recedes. As a result, simply pulling back the layer and parts connected to it and releasing the clamping engagement can thus counteract a leakage in a simple manner. In a further development, the inside of the layer facing the outside of the housing has a contour complementary to the contour of the outside of the housing. The outer contour of the housing can be round, elliptical, polygonal, square, rectangular or star-shaped and symmetrical or asymmetrical in cross-section and / or have a thread shape, longitudinal grooves, transverse grooves, projections and / or recesses, while those facing the outside of the housing The inside of the layer is provided with a substantially corresponding negative contour.

In a further development, the layer has a thickness between 0.2 mm and 10 mm, preferably between 1 mm and 8 mm, particularly preferably between 1.5 mm and 6 mm.

The layer preferably has porous material such as, in particular, fiber material. Such a further development leads to a particularly simple and effective design of the liquid reservoir in that the liquid is stored by being sucked into the porous material. In particular, when the layer is configured as a tube, with this development it is possible to use a recess or hollow filter segment from the area of filter segments for Filterzi garettes as a tubular layer. When using the known devices and methods for manufacturing filter rods, a layer can be easily manufactured and available in large quantities, which thus represents a very favorable solution.

The layer is preferably set up and designed for receiving a quantity of fluid in the form of liquid with a weight that can be a multiple of the weight of the layer. This feature can be realized in particular with a layer made of very light and very absorbent fiber material. The fiber material can have a density in the range from 0.2 to 0.45 g / cm ³ , for example 0.25 to 0.33 g / cm ³ . The fiber material can contain or consist of cellulose acetate and in particular have a total filament denier of 30,000 to 80,000, preferably 30,000 to 40,000. The liquid reservoir can also be implemented as a lightweight hollow body such as, in particular, as a double-walled sleeve with a correspondingly dimensioned, ring-shaped hollow space in cross section. The layer can preferably be provided to accommodate a liquid content between 1% and 95%, preferably between 30% and 90%, particularly preferably between 45% and 88%, based on the weight of the layer and liquid. The ratio of the liquid mass absorbed in the position to the dry mass of fiber material can be 8: 1 to 1: 1.

In a further preferred development, the layer has at least two segments, which are preferably arranged adjacent to one another and / or are provided to accommodate a liquid and / or additive that is different from the other segment and / or have the same or different wall thicknesses and / or have thickness. This development allows the evaporation device to be charged with two different liquids and / or with different dosages of a liquid and / or with spatially separate dosages of a liquid.

In order to be able to control the evaporation of different liquids individually and thus to be able to adjust the mixture resulting from the evaporated liquids to a desired ratio, at least two evaporator elements, at least two spaced apart fluid inlet openings and at least two fluid connection lines are provided from which the at least one fluid connection line extends from the at least one fluid inlet opening to the supply side of the at least one evaporator element and the at least other fluid connection line extends from the at least one other fluid inlet opening to the supply side of the at least one other evaporator element, and the at least one segment of the layer is in fluid communication with the at least one fluid inlet opening and the at least one other segment of the layer in fluid communication with the at least one other fluid inlet opening is located. Furthermore, this arrangement allows different substances to be taken up one after the other from the vaporized liquids during inhalation. Arranging two or more evaporator elements, each with an associated segment of a layer with several segments and a common air passage allows the first combination of the first evaporator element with the first segment to be operated alternately with another Combination of an additional evaporator element with an additional segment. The first combination and the second or further combination can be operated alternately and alternately, whereby excessive heating of the first combination or the further combination can be avoided. The first combination and the second or further combination can be operated in a temporally overlapping manner or simultaneously, as a result of which the same or different fluids in the form of liquids can be vaporized in a temporally overlapping manner or simultaneously. This can influence the inhalation sequence of individual components of different liquids. The liquid storage device is expediently exchangeable on the housing, with the liquid storage device optionally not having a heating device.

In a further development, at least one positioning element is provided on the outside of the housing for precise positioning and / or alignment of the liquid reservoir. The positioning element can be designed as a projection or as a rib. The positioning element can be arranged at a distance from the maximum transverse extent of the housing and in particular extend radially outward from the outside of the housing in such a way that its outer end is aligned with the maximum transverse extent of the housing, in particular has the same radial distance to the longitudinal axis of the housing as the maximum transverse extent in relation to the longitudinal axis of the housing. In this way, a liquid reservoir can on the one hand be held at the maximum transverse extent of the housing and on the other hand aligned with the outer end of the Positionierele element and secured against tilting by a further contact point or contact surface. This enables the housing to be precisely positioned in the liquid reservoir, which is particularly advantageous if the housing is provided with electrical contacts that must be aligned with a receptacle for the vaporizer device on an inhaler that has electrical contacts.

In a further embodiment, the outside of the housing is provided with an interrupted or continuously encircling, outwardly projecting shoulder having an outside. With a continuously circulating Execution, the shoulder can in particular be designed as an annular collar. Such a paragraph serves in particular as a stop for a liquid reservoir to be arranged on the outside of the housing, which results in precise positioning of the liquid reservoir relative to the housing.

In a further development of this embodiment, at least one fluid inlet opening, preferably a plurality of fluid inlet openings, is formed in the outer side of the shoulder pointing in the direction of the longitudinal axis of the housing. When arranging a liquid storage device on the outside of the housing while simultaneously resting on the shoulder, a fluid connection of the liquid storage device with a fluid connection line can easily be created.

In a further development, the outside of the shoulder has a distal section located transversely to the adjacent section of the outside of the housing, in which at least one fluid inlet opening is formed or several fluid inlet openings are formed. Thus, in this further development, at least one fluid inlet opening or several fluid inlet openings are provided on the outer edge.

In an additional or alternative further, particularly preferred development, the outside of the shoulder has a section oriented at an angle to the adjacent section of the outside of the housing, in which at least one fluid inlet opening is formed or several fluid inlet openings are formed.

First of all, the structure of an electrical or electronic inhaler is briefly explained for better understanding, as it is basically known, for example, from DE 10 2017 1 19 421 A1 or DE 10 2016 120 803 A1. The electronic inhaler has a housing that is preferably rod-shaped and cylindrical. The housing usually contains a battery and several electronic functional units, and possibly also other components. Furthermore, an air passage channel is provided in the housing between at least one air inlet opening and one mouth end. The end of the mouth is that end at which the consumer pulls for inhalation and thereby creates an air flow in the air passage. At least one air inlet opening can be formed in the end of the housing remote from the mouthpiece; but additionally or alternatively it is also possible lent to hen vorzuse at least one air inlet opening in the wall side of the housing. Furthermore, an evaporation device or evaporation unit is provided which has a heater and is connected to a liquid tank or storage device which contains an aromatic liquid or substance. During operation, when the said electronic functional units and in particular the heater in the evaporator unit are supplied with electrical current from the battery, the heater causes the aromatic liquid or substance removed from the liquid tank or storage device to evaporate. For this purpose, the air flow in the air passage passes through the evaporator unit arranged in the housing, from which the aromatic liquid or substance removed from the liquid tank or storage device evaporates and is added to the air flow in the air passage in the form of an aerosol. The electronic inhaler is preferably of modular design and divided into at least one consumption unit and at least one reusable unit. The consumption unit comprises at least the liquid tank or storage, which is thus exchangeable, not only for disposal after emptying or for refilling, but also for the purpose of offering a variety of different aromatic liquids or substances from which the consumer depends can make a selection of the taste he wants. The reusable unit forms the base body or the base housing of the electronic inhaler, in which at least the electronic functional units are contained.

In FIG. 1, an evaporation device or evaporation unit 2 designed as an evaporator capsule according to a first preferred embodiment is shown schematically in longitudinal section, which has a housing 4. The Ge housing 4 is designed as a sleeve-shaped body and has a curved or convex outer side 4 a and an inner wall 4 b, which defines an air passage 6. Thus, the air passage 6 is formed within the housing 4 and has an air inlet opening 6a on one end of the housing 4 and an air outlet opening 6b on the other end of the housing 4, so that air through the air inlet opening 6a into the air passage 6 inside the housing 4 enters and then exits again from the air outlet opening 6b. As FIG. 1 also shows schematically, the housing 4 and the air passage 6 are symmetrical to a plane of symmetry containing a central axis A or even rotationally symmetrical to the central axis A and the air passage 6 extends through the housing 4 in the direction of that central axis A. An evaporator element 8 is arranged on the inner wall 4b of the housing 4 which has a supply side 8a facing the outside 4a of the housing 4 inside the housing 4 and a discharge side 8b directed towards the air passage 6. In the exemplary embodiment shown, the evaporator element 8 is designed as a flat body and is oriented parallel to the longitudinal extent of the air passage 6, with its discharge side 8b in the exemplary embodiment shown having a planar surface that is largely aligned with the inner wall 4b of the housing 4. Other arrangements and shapes for the evaporator element 8 are also possible, although it must be ensured that the evaporator element 8 is in fluid communication with the air passage channel with its discharge side 8b, in that the discharge side 8b preferably points into the interior of the air passage channel 6 or lies in the air passage 6 without closing the air passage 6. The Verdampferele element 8 is preferably designed as a platelet-shaped substrate which contains a plurality of microchannels (not shown in detail) and forms a resistance heating element for evaporating liquid conveyed through the microchannels. The microchannels each extend from the supply side 8a to the delivery side 8b through the evaporator element 8. The substrate is electrically conductive and forms with its microchannels and the walls between the microchannels and to the boundary edges the resistance heating element. In addition to or instead of microchannels, the substrate can also be made porous, which, however, does not provide an optimal evaporation result if it is replaced. In one embodiment, provision can be made to provide heating channels (not shown in detail) within the evaporator element 8 as heating means, which are at least partially oriented essentially transversely or inclined to the discharge side 8b of the evaporator element 8. The evaporation element 8 is preferably designed so that the liquid can reach the supply side 8a to the delivery side 8b over a short distance in order to exit there in evaporated form, and is heated in the meantime in order to evaporate. As FIG. 1 also shows schematically, the housing 4 contains several fluid connection lines 10, which extend from fluid inlet openings 10a formed on the outside 4a of the housing 4 to the supply side 8a of the evaporator element 8. In the exemplary embodiment shown in FIG. 1, the fluid connection lines 10 are straight and run essentially radially with respect to the central axis A. In principle, however, it is also conceivable to give the fluid connection lines 10 a different course, provided they extend from fluid inlet openings 10a extend on the outside 4a of the housing to the supply side 8a of the evaporator element 8. To supply the evaporator element 8, supply lines 12 connected to the supply side 8a of the evaporator element 8 are accommodated in the housing 4, the free ends 12a of which are designed to produce an external interface on the outside 4a of the housing 4. In principle, however, it is also conceivable, contrary to the illustration in FIG. 4, to provide the free ends 12a of the supply lines 12 not on the outside 4a, but on the adjacent end face of the housing 4. If the evaporator element 8 is to be supplied with electrical energy, the supply lines 12 are electrical lines, the free ends 12a of which for establishing electrical contact with an external electrical energy source, not shown in detail, such as a battery or a rechargeable battery are provided.

Furthermore, a liquid reservoir 14 is arranged at least on a section of the outside 4a of the housing 4, which in the illustrated embodiment rests directly on the outside 4a of the housing 4 at least in the area of the fluid inlet openings 10a in order to establish fluid communication with the fluid inlet openings 10a. The liquid reservoir 14 is only shown in sections at this point in FIG. 1. In order to ensure that the liquid reservoir 14 contacts the fluid inlet openings 10a particularly effectively in the exemplary embodiment shown in FIG. 1, the outside 4a of the housing 4 is convex. The fluid inlet openings 10a are formed in the section that is radially furthest from the central axis A. As can also be seen in FIG. 1, in the exemplary embodiment shown, the liquid reservoir 14 has a layer 16 which at least partially surrounds the housing 4 on its outer side 4a and preferably rests against the outer side 4a of the housing 4 without play or pretensioned at least partially. Here, the layer 16 can give the housing 4 in sections in its circumferential direction or have the shape of an encompassing tube. The thickness of the layer 16 of the liquid reservoir 14 is preferably between 0.2 mm and 10 mm, preferably between 1 mm and 8 mm, particularly preferably between 1.5 mm and 6 mm. In the exemplary embodiment shown, the layer 16 of the liquid reservoir 14 has porous material, preferably fiber material, or consists of such a material. The absorption of aromatic liquid or aromatic liquid in the liquid reservoir 14 can thereby take place by simple suction. This not only leads to a particularly simple and at the same time effective storage of the liquid in the liquid reservoir 14, but also allows a particularly simple and inexpensive design of the liquid reservoir 14. The layer 16 is directed and designed to accommodate a quantity of liquid with one Ge weight that can be a multiple of the weight of the layer 16.

The fluid connection lines 10 are preferably designed as tubes or capillaries and have a diameter that effects capillary liquid delivery, preferably in a range between 5 μm and 100 μm, and in particular a length between 0.5 mm and 5 cm, preferably between 1 mm and 10 mm. The diameter can be constant and / or increase and / or decrease over the length of the fluid connection lines 10 at least in sections. In another embodiment, it is possible to use the fluid connection lines 10 as an elongated gap with a gap width that effects capillary liquid delivery, preferably between 5 μm and 200 μm, particularly preferably between 10 μm and 100 μm, and in particular a length between 0.5 mm and 5 cm, preferably between 1 mm and 10 mm. The gap width can be constant and / or increase and / or decrease over the length of the fluid connection lines 10 at least in sections and / or the gap can be designed as an annular gap. Thus, the capillary action of the fluid connection lines 10 ensures a transport of the liquid absorbed in the layer 16 of the liquid reservoir 14 to the supply side 8a of the evaporator element 8, where it then occurs into the evaporator element 8, it is heated within the evaporator element 8 and thus evaporated and then enters the air passage 6 in the evaporated state in order to enrich the air flow there in the form of gas and / or aerosol. The amount of aerosol generated in the evaporator unit 2 can be set or changed by changing the electrical voltage applied to the evaporator element 8, in particular with regard to the control frequency and the associated switching on and off processes of the heating device and the substrate. Additionally or alternatively, it is also conceivable to provide several evaporator elements 8, which can be switched on or off as required.

It is particularly advantageous to orient the delivery side 8b of the vaporizer element 8 in relation to the air passage 6 in such a way that fluid exiting from the delivery side 8b of the vaporizer element 8 in the vaporized state is essentially miscible in a cross-flow with the air passed through the air passage 6. In the exemplary embodiment shown in FIG. 1, this is achieved in particular in that the delivery side 8b of the evaporator element 8 is essentially planar and is oriented essentially parallel to the longitudinal extension of the air passage 6 in the direction of the central axis A.

The evaporator element 8 designed as a substrate can form a substantially rectangular discharge side with an edge length K1 (see FIG. 1) and an edge length K2 (see FIG. 2a), where K1 can be equal to or greater than K2. K1 can be around 2.5 to 3.5 mm, K2 can be around 1.5 to 2.2 mm. K2 can, for example, be in the range of 2 mm +/- 0.5 mm and K1, for example, in the range of 3 mm +/- 0.5 mm. The number of microchannels along the direction of the edge length K2 is preferably greater than or equal to 8 and / or preferably less than or equal to 30. The number of microchannels along the direction of the edge length K1 is preferably greater than or equal to 12 and / or preferably less than or equal to 45 .

In a further embodiment, a recess Z1 (see FIG. 1) can be provided in the wall of the housing 4. A separate insert part in which the fluid connection lines can be accommodated can be accommodated in the recess Z1 10 are arranged. In the wall of the housing 4 a recess Z2 is seen easily. The evaporator element 8 is received in the recess Z2. The optional recess Z1 and the recess Z2 can both be arranged one behind the other in a region of the wall of the housing and in the direction of the passage 6. The optional recess Z1 and the recess Z2 can both be arranged one after the other in a region of the wall of the housing, forming a stepped insertion and receiving opening. The optional recess Z1 can be dimensioned such that the separate insert part is received in a preferably light press fit. In the present embodiment, the recess Z2 is dimensioned such that the evaporator element 8 is received in a preferably light press fit.

In FIGS. 2a to 2f is in cross section the design and arrangement of Ge housing 4, air passage 6, evaporator element 8 and liquid reservoir 14 in different embodiments. In the case of the FIGS. 2a and b, the housing 4 is designed as a body of revolution and the layer 16 forming the liquid reservoir 14 is in the form of a tube which rests against the outside of the housing 4 with essentially no play or is pretensioned. The same also applies to the embodiment shown in FIG. 2c, which, however, differs from the embodiment according to FIGS. 2a and b differ in that the layer arched around the housing 4 and formed by the liquid reservoir 14 is not a closed tube but has a C-shaped cross section with an elongated free space 18; this embodiment allows the use of prefabricated fleece, which is placed around the housing 4 to form the layer of the liquid reservoir 14. Furthermore, the exemplary embodiment according to FIG. 2b differs from the exemplary embodiment according to FIG. 2a in that the housing 4 is divided into two housing parts 4c, 4d which form two housing shells and are connected to one another via a hinge 4e. Such an arrangement is particularly advantageous for production, since in the open state of the two housing parts 4c, 4d, the evaporator element 8 can be mounted particularly easily, while in the closed state the two housing parts 4c, 4d then form the finished housing 4 and preferably are also non-releasably locked to one another, for example by gluing or a tongue and groove connection. In Fig. 2d another embodiment is shown that differs from the exemplary embodiment from FIG. 2a in that the cross section is not circular, but elliptical.

Instead of a rotationally symmetrical or otherwise round cross-sectional shape, as shown by way of example in FIGS. 2a to d, any other cross-sectional shapes are basically also conceivable for the housing 4 and the air passage 6 contained therein, including, for example, FIGS. 2e and f, in which the housing 4 and the air passage 6 are shown, for example, with a triangular cross-sectional shape. Similar to the embodiment shown in FIG. 2b, the embodiment shown in FIG. 2f also differs from the embodiment according to FIG. 2e in that the housing 4 is divided into two housing parts 4c, 4d, the first housing part 4c being the two Includes legs of the triangular shape of the housing 4 and forms an upper housing part or a type of cover, while the second housing part 4d forms the base of the triangular shape of the housing 4 and thus the lower housing part or the bottom. By dividing the housing 4 into two housing parts 4c, 4d in the embodiment according to FIG. 2f, advantages as in the embodiment according to FIG. 2b can also be achieved. One advantage here is that an evaporator element 8 can be installed more easily in the open state, while the two housing parts 4c, 4d then form the finished housing 4 in the closed state. In the embodiment according to FIG. 2f, suitable connection means 4f are provided for locking the two housing parts 4c, 4d to one another, which for example form a plug-in or tongue-and-groove connection. For a then non-releasable locking, the connecting means 4f can be provided with corresponding latching means or can be glued accordingly. The particular advantage of an embodiment according to FIG. 2f is that the second housing part 4d can be shaped as a bottom part, which has an easily manageable cuboid shape, which allows particularly good accessibility during assembly and easy transport through assembly lines, as well as a secure hold and alignment during one assembly step. In principle, other types of connecting means such as, for example, the joint used in the exemplary embodiment according to FIG. 2b are also conceivable. Furthermore, the exemplary embodiments according to FIGS. 2e and f recognize the use of two evaporator elements 8. As mentioned above, the amount of aerosol generated can not only be changed by changing the electrical voltage applied to the United evaporator element 8, but it also depends on the number of evaporator elements 8 used and, in particular, special parallel used. The exemplary embodiments according to FIGS. 2e and f, whereby the use of more than two evaporator elements 8 is basically also conceivable. The advantage of using a plurality of vaporizer elements 8 also lies in the fact that the desired amount of the aerosol to be generated can be changed or adjusted accordingly by optionally switching on or off part of the vaporizer elements 8.

Finally, in FIGS. 2a to f shown exemplary embodiments that the inside of the layer 16 of the liquid reservoir 14 facing the outside 4a of the housing 4 preferably has a contour complementary to the contour of the outside 4a of the housing 4, while the outside 14a of the liquid reservoir 14 preferably has one Has round, in particular circular or elliptical cross-sectional shape.

While in the FIGS. 2b and f, the housing 4 is divided into two housing parts 4c, 4d arranged transversely to the orientation of the air passage 6 side by side or one above the other, it is additionally or alternatively also conceivable to divide the housing 4 in two in the direction of the orientation of the air passage channel 6 and thus also the central axis A to subdivide housing parts arranged one behind the other, as is shown with reference to the housing parts 4g in the exemplary embodiment according to FIG. 2g. In the embodiment according to FIG. 4g, two housing parts 4g shaped as housing caps are provided, which can be pushed into one another at their respective open edge. The outer contour of the overall housing is designed in a stepped manner, as a result of which individual stepped shoulders for receiving layers 16 can be formed and good tension fits for the layers 16 can be achieved. Finally, it should be noted that, in deviation from the in FIGS. 2b, e and g, the housing 4 also in more than two in the direction of the orientation of the air passage channel 6 and thus the central axis A one behind the other and / or transversely to the orientation of the air passage and thus the central axis A side by side housing parts can be divided.

A consumable article for inhalation can be designed as a cartridge 20. Embodiments of a cartridge are shown in FIGS. 3a, 5d, 6b and 7c-7e are shown schematically. The aforementioned figures show an exemplary embodiment of a cartridge for an inhaler, with a mouth end, an insertion end opposite the mouth end, a longitudinal axis L and a layer 16 containing a layer of fiber material, which has a casing 20a and a shell 20a delimiting the layer of fiber material to the outside has a cavity 20b extending along the longitudinal axis L, in which the layer of fiber material forms a liquid reservoir 14 and in the layer a mass of a formulation of ingredients of a consumable article in the form of a smoking article 20 or a medical article is absorbed in a capillary manner and in which an an exit barrier M for the formulation and / or an exit barrier E for the formulation is formed at the end of the mouth, with the exit barrier M and the exit barrier E preferably as a fiber cavity sealant in the form of an adhesive, a meltable and self-locking agent Fes terming substance, as a layer recess in the form of a layer set back with respect to the mouth end or the insert end and the shell or as a sealing ring in the form of an end cover, in particular pretensioned onto the layer. The exit barriers M and E are particularly emphasized in FIG. 7e, while they are only indicated schematically in the remaining figures and are provided with the corresponding reference symbols M and E. In the Ausfüh approximately example according to FIG. 7e, the exit barrier M is ausgebil det as a sealing element 43. In the embodiment according to FIG. 7e, the exit barrier E is designed as a telement 43 you. Between two adjacent segments of a layer 16, as exemplified by the embodiment of a cartridge according to FIG. 7e, an exit barrier can be provided, which is preferably optionally arranged on one segment or on the other segment or on both segments of the layer 16 can be. Each of the segments can also have an exit barrier at the corresponding end of the respective segment, which faces the respective other end of the other segment. In Fig. 3a, a tubular cartridge 20 is shown in longitudinal section. The cartridge 20 has a sleeve 20a which forms a circumferential wall. The shell 20a preferably has the shape of a cylinder. The cartridge 20 includes a cavity 20b. The cartridge 20 is open at a first end 20c and is closed at the opposite second end 20d by a filter element 22 in the illustrated embodiment. The arrangement shown in FIG. 1 is received in the cavity 20b of the cartridge 20, so that the outside of the tubular liquid reservoir 14 rests against the inside of the shell 20a, which thus encloses the tubular liquid reservoir 14. Thus, the cartridge 20 can be designed and used together with the filter element 22 in the manner of a cigarette pod. As FIG. 3a also reveals, recesses 24 are made in the end face of the housing 4 facing the free first end 20c of the cartridge 2.

The sleeve 20a of the cartridge 20 can consist of plastic or metal. Alternatively, however, it is also conceivable to use wrapping paper, which is known from the manufacture of conventional cigarettes, as the material for the cover 20a. The filter element 22 preferably has filter tow material which can have undergone a corresponding preparation in the same or a similar manner as in the production of conventional filter cigarette filters; In principle, it is also conceivable to use filters manufactured for the production of conventional filter cigarettes as the filter element 22. Furthermore, it is also conceivable to use a multifilter element known from the manufacture of conventional filter cigarettes as the filter element 22, which thus contains several filter segments. Finally, a hollow filter element can also be used as the filter element 22.

Thus, according to the embodiment shown in Fig. 3a, the cartridge 20 is a component that contains the vaporizer unit 8, the liquid reservoir 14 and the filter element 22 and thus forms a consumable smoking article that is inserted into an electronic inhaler 30, such as the Figs. 3b and c reveal. The inhaler 30, shown schematically in longitudinal section in FIG. 3b, has a base body 30a and a sleeve-shaped section 30b extending in the longitudinal direction from the base body 30a. The base body 30a contains functional units 32, such as an electronic controller and possibly also a battery, and is delimited on the front side by a free first end 30c. The sleeve-shaped section 30b adjoining the base body 30a closes a cavity 34 which is open at the free second end 30d of the inhaler 30 located away from the first end 30c. The cavity 34 has the shape of a cylinder with an inner diameter which corresponds approximately to the outer diameter of the cartridge 20 of FIG. 3a. The inner diameter of the cavity 34 is optionally designed to be slightly larger than the outer diameter of the cartridge 20, so that the cartridge 20 can be inserted reliably and there is only a small amount of play between the inner diameter of the cavity 34 and the outer diameter of the cartridge 20. Inside the cavity 34 is a sleeve-shaped shaft 36 which extends from the base body 30a in the direction of the second end 30d of the inhaler 30 and ends with an open free end 36a at a distance from the second end 30d within the cavity 34. An air passage 38 is formed within the main body 30a of the inhaler, which is open at the first end 30c to form an air inlet opening 38a and opens into the cavity 36b of the shaft 36. As can also be seen in FIG. 3b, the shaft 36 is arranged centrally within the cavity 34 and extends in the direction of the central axis A. The shaft 36 is also preferably cylindrical, so that in this case a coaxial arrangement of the with respect to the central axis A Shank 36 is given opposite the cylindrical cavity 34.

The cartridge 20 forming a consumable smoking article in the configuration shown in FIG. 3a can now be inserted as a consumable smoking article into the cavity 34 within the inhaler 30 by inserting the first end 20c through the open second end 30d of the inhaler 30 into the cavity 34 is inserted until the arranged inside the cartridge 20 Ver evaporator unit 2 with its housing 4 in contact or engagement with the free end 36a of the shaft 36 comes. As can be seen in FIG. 3c in conjunction with FIG. 3a, the recess 24 in the housing 4 of the evaporator unit 2 is designed such that it receives the free end 36a of the shaft 36 in order to create a plug connection for receiving the cartridge 20 on and in the inhaler 30 in this way. Connection means (not shown) are provided in the contact area between the housing 4 of the evaporator unit 2 and the free end 36a of the shaft 36 to connect the free ends 12a of the supply lines 12 (FIG. 1) running inside the housing 4 to correspondingly in the Wall of the shaft 36 and within the base body 30a of the inhaler 30 and electrical lines 41 leading to the functional units 32 to be connected. In the embodiment shown in Fig. 3c, the cartridge 20 is only partially received in the cavity 34 of the inhaler 30 and is therefore exposed in the loading area of the filter element 22, which thus forms the end of the mouth. The described arrangement also has the consequence that a continuous channel is created from the air inlet opening 38a at the front first end 30c of the inhaler 30 to the filter element 22, which in turn starts from the air passage 38 inside the main body 30a of the inhaler 30, from the cavity 36b of the shaft 36, is formed by the air passage 6 within the housing 4 of the evaporator unit 2 and the remaining cavity 20b of the cartridge 20. As FIG. 3c also shows, in contrast to the illustration in FIG. 3a, a further sleeve 26 is arranged within the cavity 20b of the cartridge 20 between the housing 4 of the evaporator unit 2 and the filter element 22, which is a spacer between the housing 4 and the filter element 22 in order to enable a defined positioning of the housing 4 of the evaporator unit 2 within the cavity 20b of the cartridge 20. In Fig. 4a a portion of a cartridge 20 is shown in longitudinal section in extracts similar Lich the cartridge shown in Fig. 3a with an evaporator unit 2 now formed as an evaporator sleeve according to a further embodiment. The difference to the first preferred embodiment according to FIG. 1 is in particular that the outside 4a of the housing 4 is not convex, but rather cylindrical and is additionally provided with a radially outwardly extending projection 42 and also the air passage 6 in the area of the evaporator element 8 has a bottleneck. In principle, however, it is also conceivable in this exemplary embodiment, similar to the first The embodiment of Fig. 1, the outside 4a of the housing 4 form convex trainees and provide the air passage channel 6 without a constriction.

As FIG. 4a also shows, the radial projection 42, which is preferably designed as a circumferential annular collar, divides the layer 16 of the liquid reservoir 14 into two segments, one segment of which is on one side of the projection 42 and the other segment rests against the other side of the projection 42. The projection 42 thus also forms a shoulder which takes on the function of a stop for the two separate segments of the layer 16 of the liquid reservoir 14 for their precise positioning. The arrangement of the evaporator element 8 in the region of the narrowest point of the air passage 6 in the preferred embodiment of FIG. 4a leads to a particularly good mixing of the vapor emerging from the evaporator element 8 with the air flowing through the air passage 6. Because with the choice of a special channel shape and / or due to special changes in cross-section of the air passage channel 6, the mixing of the air with the steam can be influenced in a targeted manner. Therefore, it is also fundamentally conceivable, in the first preferred embodiment according to FIG. 1, instead of straight inner walls with a constant distance or cross-section, the air passage 6 has a different shape, in particular with a cross-section that is variable over its length, such as the one in 4a to give the exemplary embodiment shown.

As FIG. 4a also shows, in the exemplary embodiment shown there, the fluid connection lines 10 run at least in sections through the projection 42. The fluid connection lines 10 on the right in the view of FIG. 4a extend in the radial direction and end completely within the projection 42 , where they are then in fluid communication with the adjacent layer 16 of the liquid reservoir 14 on the right side 42a of the projection 42 via air inlet openings 10a. The left in the view of Fig. 4a fluid connection lines 10, however, run a little obliquely and end not only on the opposite side 42a of the projection 42, but also partially in the outside 4a of the housing 4, in order to use fluid inlet openings 10a formed there in fluid communication with the adjacent layer 16 of the Liquid storage 14 to stand. Preferably, however, only one of the two possibilities described above for the course of the fluid connection lines 10 should be seen before, both possibilities in Fig. 4a are formed for the sake of simplicity. Due to the subdivision of the layer 16 of the liquid reservoir 14 by the protrusion 42 into two separate segments, it is now possible, if necessary, to fill the liquid reservoir 14 with two different aromatic liquids or substances by the one side of the projection 42 angren one layer 16 contains a different liquid than the other layer 16 adjacent to the opposite side of the projection 42.

This is indicated schematically in FIG. 4b by different hatching of the layers 16. In this embodiment, the evaporator element 8 is simultaneously supplied with the two different liquids or substances via the fluid connection lines 10, whereby a corresponding mixing of these two liquids or substances then takes place in the evaporator 8. Incidentally, for a better understanding of FIG. 4b, it should be pointed out at this point that, in contrast to FIG. 4a, the casing 20a of the cartridge 20 is not shown.

The exemplary embodiment shown in FIG. 4c differs from the exemplary embodiment according to FIG. 4b in that two evaporator elements 8 are provided. The evaporator elements 8 are not arranged in the area of the protrusion 42, but one evaporator element 8 is positioned in the area of the egg nen layer 16 of the liquid reservoir 14 and connected via fluid connection lines 10 only to this layer and the other evaporator element 8 is in the area of the other layer 16 of the liquid reservoir 14 and connected via fluid connection lines 10 only to that layer. In this way it is possible to control the evaporation of the two different liquids both in terms of their amount and in terms of time, which makes it possible, for example, to be able to enjoy the substances from the two different evaporated liquids one after the other while inhaling. In this embodiment, the evaporator elements 8 are accommodated in recesses Z2 and close approximately with the contour of the passage 6. Optionally, in a modification of this embodiment or other embodiments, a recess K1 (see FIG. 4c) can be provided, in which an insert part that forms the passage channels 10 is received.

Furthermore, it is fundamentally possible not only to subdivide the position 16 of the liquid reservoir 14 into at least two segments in order to store different liquids, as was previously the case with the aid of FIGS. 4b and c, but it is alternatively or additionally basically also possible to combine different evaporator units with one another. For example, FIG. 5a shows a combination of an evaporator capsule 2 according to the first embodiment of FIG. 1 with an evaporator sleeve according to the embodiment of FIG. 4c. A tubular liquid reservoir 14 is then arranged around this combined arrangement, which is shown schematically in FIG. 5b. The layer 16 of the liquid reservoir 14 can be divided into three separate segments, each segment supplying one of the three vaporizer elements 8 present in this combination, for which details refer to the descriptions of the first embodiment of FIG. 1 and of the embodiment of FIG. 4c is referred. To produce a consumable smoking article, the cartridge 20 already described in connection with FIG. 3a is used, as is shown again in FIG. 5c in the empty state, and the arrangement of FIG. 5b is inserted into its cavity 20b. The cartridge 20 configured as a consumable smoking article, as shown in FIG. 5d, is then used in the form shown in FIGS. 3b and c shown inhaler 30, including to avoid repetitions with regard to the structure and configuration of the inhaler 30 to the preceding description of FIGS. 3b and c.

In Fig. 6a, an inhaler 30 according to a further exemplary embodiment is illustrated, which differs from the inhaler 30 according to the exemplary embodiment shown in Fig. 3b in that instead of a shaft, a slide-on cone designed as a vaporizer unit 2 is provided, which is provided within the Cavity 34 is arranged on the base body 30a, wherein the arrangement can be made either non-releasable or releasable. As FIG. 6a also shows, in the illustrated embodiment of the evaporator unit 2, the outside 4a of the housing 4 is adjacent to the base body 30a of the inhaler 30 located cylindrical section 4aa and a conical section 4ab extending through the open second end 30d of the inhaler 30. In the embodiment example for the evaporator unit 2 shown in FIG. 6a, an evaporator element 8 and the fluid connection lines 10 are contained in the area of the cylindrical section 4aa of the outside 4a in the housing 4 and, in this embodiment too, the air passage 6 extends through the shaft-shaped housing 4. In contrast to that in FIGS. 3b and c and 5e shown embodiment of the inhaler 30 is provided in this exemplary embodiment with lateral or radial air passage channels 39, which run through the base body 30a and are open on the one hand via air inlet openings 39a on the long side of the inhaler 30 and on the other hand with The point marked with the reference symbol “39b” in the air passage 6 of the housing 4 open. Of course, it is also conceivable in this exemplary embodiment, in addition to or instead of the lateral air passage channels 39, to have at least one air passage channel 38 extending in the longitudinal direction and thus in the direction of the longitudinal extension of the inhaler 30, as in the case of the one in FIGS. 3b and c and 5e illustrated embodiment vorzuse hen. Conversely, it is of course also conceivable for the inhaler 30 according to the other exemplary embodiments described here to provide the radial or lateral air passage channels 39 shown in FIG. 6a in addition to the longitudinally extending air passage channel 38 or instead of such a channel. With regard to further details regarding the construction and function of the evaporator unit 2, reference is made to the description of the first exemplary embodiment according to FIG. 1, which also applies mutatis mutandis to the embodiment shown in FIG. 6a.

In Fig. 6b, the associated cartridge 20 is shown, which differs from the cartridge shown in Fig. 3a from the fact that the filter element 22 is a hollow filter element with an opening into the cavity 20b of the cartridge 20 opening 22a and no evaporator unit contains, since an evaporator unit 2, as mentioned above, is provided as a component belonging to the inhaler 30 in the embodiment described here. In addition, to avoid repetition, reference is made to the description of the cartridge 20 shown in FIG. 3a and the inhaler 30 shown in FIG. 3b. As FIG. 6c shows, the cartridge 20 of FIG. 6b is pushed onto the housing 4 of the evaporator unit 2, which is designed here as a push-on cone, and is partially received by the cavity 34 of the inhaler 30, while it is in the area of the filter element 22 that forms the mouth end open second end 30d of inhaler 30 protrudes. Therefore, in this embodiment too, the diameters are dimensioned so that the outer diameter of the cartridge 20 corresponds to the inner diameter of the cavity 34 in the inhaler 30 and the inner diameter of the tubular liquid reservoir 14 arranged on the inside of the shell 20a of the cartridge 20 corresponds to the outer diameter of the cylindrical section 4aa the outside 4a of the housing 4 corresponds. Furthermore, it should be noted that in this embodiment, preferably at the end 20c of the cartridge 20 remote from the filter element 22, the free ends 12a of the electrical supply lines 12 (FIG. 1) running inside the housing 4 and in the cavity 34 of the inhaler 30 correspond Connection means are provided in order to establish an electrical connection between the electrical supply lines laid in the inhaler 30 and the electrical supply lines running in the housing 4 when the cartridge 20 is pushed into the cavity 34 of the inhaler 30, but this is not shown in FIG. 6c . In Fig. 7a a further embodiment of an inhaler 30 is shown, wel Ches is particularly similar to the embodiment shown in Fig. 3b, but compared to that embodiment, the shaft 36 is extended beyond the open second end 30d of the inhaler 30 and with a first Ab Section 40, which is adjacent to the base body 30a of the inhaler 30 and has a convex shape increasing the width or diameter, and is provided with a second section located away from the base body 30a of the inhaler 30, which forms an evaporator unit 2, which is in Essentially is constructed in the same way as the first exemplary embodiment shown in FIG. 1, to the description of which reference is therefore made to avoid repetition. As can be seen from FIG. 7a, the maximum width or the maximum diameter of the section 40 of the shaft 36 and of the housing 4 of the evaporator unit 2 integrated in the shaft 36 is essentially the same. The Pro See the section 40 and its design allow a guide and from align an article to be inserted in the form of a cartridge 20. It can thus be ensured that the article to be inserted in the form of a cartridge 20 can be positioned exactly with the desired clearance to adjacent walls and tilting movements can be prevented. As FIG. 7a also shows, only one evaporator element 8 is present in the exemplary embodiment shown in this figure. Finally, the formation and arrangement of the section 40 and the housing 4 of the evaporator unit 2 can in principle also be interchanged with respect to the illustration of FIG. 7a. The exemplary embodiment shown in FIG. 7b differs from the exemplary embodiment shown in FIG. 7a in that instead of an outwardly curved leading and positioning, "evaporation-passive" section 40, a further evaporator unit 2 is provided, which is also similar to that shown in FIG. 1 illustrated first embodiment is formed. The added further evaporator unit 2 is now additionally provided with two evaporation elements 8 compared to the “evaporation-passive” section 40. This configuration therefore also has the advantages of the configuration with the “evaporation-passive” section 40. In contrast to the first embodiment shown in FIG. 1 and the embodiment shown in FIG. 7a, at least two evaporator elements 8 are provided in each evaporator unit 2, such as 7b also shows schematically.

In the case of the FIGS. 7a and b is the evaporator unit 2 (Fig. 7a) or the evaporator units 2 (Fig. 7b) are a fixed, quasi-integral part of the inhaler 30. In the cavity 34 of the inhaler 30, only a cartridge 20 has to be inserted, which still contains a tubular liquid reservoir 14, but not an evaporator unit. A cartridge 20 with such a configuration is shown by way of example in Fig. 7c, which largely corresponds to the cartridge shown in Fig. 5c, but in contrast to this contains the tubular liquid reservoir 14. FIG. 7d shows a further exemplary embodiment for a cartridge 20 which differs from the exemplary embodiment according to FIG. 7c in that the filter element 22 is provided with its own wall 22b, which consists of Plastic or metal or simple wrapping paper can consist of conventional cigarettes and with which the filter element 22 can be attached to the cartridge 20 by an overlapping arrangement with the casing 20a of the cartridge 20 ending here at the filter element 22, and also the liquid storage 14 after Type of separate segments has two layers 16 lying one behind the other, which can preferably accommodate different liquids, which is indicated in Fig. 7d by different hatching.

To prevent unwanted leakage of liquid from the layer 16 of the liquid reservoir 14 into the filter element 22 and / or in the direction of the base body 30a of the inhaler 30 and / or in the event that the liquid reservoir 14 separates at least two segments from one another in the manner of separate segments Layers 16 include, to avoid undesired mixing of the liquids between these layers 16, corresponding sealing elements 43 can preferably be provided, as exemplified by the embodiment shown in FIG. 7e. In this embodiment, ring-shaped circumferential sealing elements 43 are provided on the inside of the shell 20a, of which a first sealing element 43 between the first end 20c of the cartridge 20 and the adjacent layer 16 of the liquid reservoir 14, a second sealing element 43 between two adjacent layers 16 of the liquid reservoir 14 and a third sealing element 43 between the filter element 22 and the adjacent layer 16 of the liquid reservoir 14 is arranged. To this extent, the exemplary embodiment according to FIG. 7e is a further development of the exemplary embodiment from FIG. 7d.

A cartridge 20 in which the liquid reservoir 14 comprises at least two separate layers 16 is primarily suitable for the use of at least a corresponding number of vaporizer units 2, of which one evaporator unit 2 with one of the layers 16 of the liquid reservoir 14 is in fluid Connection can be brought. Thus, a cartridge 20 is suitable in accordance with the methods shown in FIGS. 7d and e shown embodiments for use in an inhaler 30 according to the embodiment shown in Fig. 7b. A corresponding combination is shown by way of example in FIG. 7f, which shows the inhaler 30 according to the embodiment shown in FIG. 7b, into which a cartridge 20 according to the embodiment shown in FIG. 7e is inserted. As can be seen in particular from FIG. 7f, the one evaporator unit 2 is located in FIG fluid communication with one layer 16 and the other vaporizer unit 2 in fluid communication with the other layer 16 and, furthermore, the sealing element 43 arranged at the first end 20c of the cartridge 20 seals the adjacent layer 16 from the base body 30a of the inhaler 30. Since the based on FIGS. 6 and 7, the vaporizer unit (s) 2 is (are) provided on the inhaler 30 and therefore the cartridge 20 to be used for this purpose only needs to be provided with the liquid reservoir 14 and the filter element 22, forms a cartridge 20 configured in this way A single-use component is preferred, whereas the inhaler can be used multiple times.

The cartridge described at the outset and above can contain a formulation of active ingredients of medicaments in the form of medicaments. The means that are mentioned and described in paragraphs 219 to 283 of DE 20 2013 105 420 U9 are provided as medicaments which are present in the cartridge in the form of a formulation. The relevant disclosure of DE 20 2013 105 420 U9 should be included in the present case in full in the form of an explicitly and specifically cited reference document. For further disclosure on the present formulation, reference is also explicitly made to DE 20 2013 105 420 U9 and specifically to paragraphs 284 and 285 there, which are to be included in the present fully in the form of an explicitly and specifically cited reference document. In the case of the cartridge according to the invention, provision is preferably made in the formulation to use at least a portion of water as the carrier and / or preferably to dissolve and / or suspend solid constituents of active ingredients such that an active ingredient particle size diameter of 200 μm, preferably 150 pm is not exceeded.
