DETAILED DESCRIPTION OF EMBODIMENTS

With reference firstly to FIGS. 1 and 2 of the drawings, a personal vaporizer device 1 in the form of electronic cigarette or “e-cigarette” is illustrated in different positions and in partial cross-section. The device 1 includes a replaceable cartridge 2 which is attached at one end region 3 of an elongate body 4. The elongate body 4 in turn comprises a casing 6 which encloses a power supply unit in the form of a battery unit D for supplying electrical power to the device 1. The casing 5 of the elongate body 4 includes a cover member 6 which is movable in a longitudinal direction of the body 4 between a first position A (i.e. shown in FIG. 1) and a second position B (i.e. shown in FIG. 2). In this regard, the cover member 6 comprises a front cover panel 6″ which extends over a front side of the body 4, and a rear cover panel 6″, which extends over a rear side of the body 4.


As can be seen in drawing FIGS. 2, the cartridge 2 comprises a housing 7 that encloses a reservoir 8 for storing a liquid to be vaporized. The housing 7 has a flat base 7′ and generally vertically extending sides 7″ which transition at curved upper shoulder regions 7″ to form or terminate at a mouthpiece 9 at a top of the cartridge 2. In this way, the shell of the housing 7 encloses the reservoir 8 ′ to form a small 5 tank for storing the liquid (i.e. of a type known in the art) to be vaporized for inhalation by a user of the e-cigarette. Furthermore, the cartridge 2 includes an airflow channel C which extends centrally through the housing 7 from the base 7″ to the top and is configured to guide the vapour to the mouthpiece 9 for inhalation by the user. The airflow channel C has a generally circular cross-section and is surrounded by the reservoir 8. In order to generate the vapour, the cartridge 2 incorporates a vaporizer unit having an electric heater with a heating element or wire provided wound in a coil within the airflow channel C for heating the liquid to be vaporized to generate the vapour to be inhaled. The vaporizer unit (not shown) further comprises a liquid delivery means which is configured to convey the liquid from the reservoir 8 to the heating wire for vaporization.


Referring to drawing FIGS. 1 and 2, the cover member 6, which is comprised of the front and rear panel members 6′,6″, is movable in a longitudinal direction of the device body 4—e.g. by siding or in translation—between the first position A shown in FIG. 1 and the second position B shown in FIG. 2. In the first extended position A, the replaceable cartridge 2 comprising the reservoir 8 and the vaporizer unit 10 is substantially covered or obscured by the cover member 6. In this way, the cover member 6 provides a physical barrier for protecting the cartridge 2 in the first position A. Nevertheless, the volume or amount of liquid in the reservoir 8 of the cartridge 2 remains visible when the cover member 6 is in the first position A. That is, although the cartridge 2 is largely covered or obscured by cover member 6 is in this position, a window may be provided in the cover member 6 and/or a side region S of the cartridge 2 remains uncovered by the cover member 6 and may include a window W for a user to determine visually how much liquid remains in the reservoir 8.


For sliding or moving the cover member 6 relative to the remainder of the casing 5 between the first and second positions A, B, at least one or both of the front and rear panel members 6′,6″ may be held and engaged between a thumb and finger of the user. In the second position B, the cover member 6 is retracted to leave the cartridge 2 either partially or substantially uncovered or unobscured. That is, in the second position B the cover member 6 is retracted from the cartridge 2 in the longitudinal direction to a use position or an activated position for the e-cigarette or vaporizer device 1, To this end, the body 4 includes a switch 17 provided in the form of a round button set within an opening 18 in the cover member 6. The switch or button 17 is configured to activate the device 1 and the switch 17 is in operative connection with a part of the controller or control unit below the cover member 6, In this regard, the device 1 may be designed to only be able to be activated via the switch 17 when the front and rear panels 6′,6″ are moved from the first position A to the second position B. The switch 17 is surrounded by a ring-shaped indicator 19 which illuminates on the front panel 6″ for indicating an operational status of the device 1. These elements of the vaporizer device 1 will be described in greater detail below.


In addition, the second position B of the cover member 6 is designed for removing the cartridge 2 from, and/or for connecting a cartridge 2 to, the body portion 4 of the personal vaporizer device or e-cigarette 1. As noted above, the cartridge 2 is configured to be connected to the end region 3 of the body portion 4. This end region 3 of the elongate body 4 thus preferably includes one or more electrical contacts 14 for making an electrical connection with one or more complementary electrical connectors provided on the cartridge 2 for connecting electrical power to the heater of the vaporizer unit within the cartridge 2.


Drawing FIG. 3 shows a perspective view of a cartridge 2 according to a similar embodiment to the one described above. As described previously, the cartridge 2 here typically includes a housing 7 enclosing a reservoir 8 for storing the liquid to be vaporized and defining an airflow channel C which extends centrally through the housing 7 to a mouthpiece 9 at a top of the cartridge 2. Further, the cartridge 2 includes a vaporizer unit (not shown) having an electric heater with a heating element provided wound in a coil within the airflow channel C for heating the liquid to be vaporized to generate the vapour to be inhaled. The vaporizer unit comprises a liquid delivery means configured to convey the liquid from the reservoir 8 via capillary action or other known mechanisms.


Referring now to FIGS. 4 to 6 of the drawings, three different types of mechanical and electrical connections between the cartridge 2 and power supply (e.g. battery unit D) via the end region 3 of the body 4 of the personal vaporizer device 1 are schematically illustrated. In each case, the cartridge 2 is configured for a push-on/pull-off type connection into the open upper end region 3 of the casing 5 of the device. In FIG. 4, the sides 7″ of the cartridge housing 7 include resilient or flexible members 31 (e.g. formed as leaf-springs or cantilevers) having projecting lugs 32 for receipt or engagement in complementary recesses 33 formed on an inner side of the casing 5. Electrical contact elements 14 are provided separately for power supply to the controller 13 and heater via electrical contacts provided below the cartridge 2. In the embodiment of FIG. 5, the sides 7″ of the cartridge housing 7 are received in the open upper end region 3 of the casing 5 and resilient electrical contact elements 14 extend upwards from the power supply and engage electrical contacts 34 provided in the sides 7″ of the cartridge housing 7. In the embodiment of FIG. 6, by contrast, a mechanical connection is effected via magnetic connector elements 35 provided on both the cartridge 2 and the body part 4 of the personal vaporizer device 1 at the end region 3. The electrical connection again occurs separately via electrical contacts 14 below the base 7′ of the cartridge housing 7.


With reference now to FIGS. 7 to 9 of the drawings, the geometry and construction of the cover member 6 can be more clearly seen. In particular, the front panel 6′ of the cover member is functionalized by its convex outer shape, its thickness and flexibility. In particular, the panel 6′ is not only configured to move between the first and second positions A, B but may also bend and form as a user interface for operation of the device 1. In this regard, it has already been noted above that the front panel 6′ of the cover member 6 includes user interface elements, such as the switch 17 in the form of a button set within the opening 18 in the cover member 6 and surrounded by a ring-shaped indicator 19 which illuminates the front panel 6′ for indicating an operational status of the device 1. The switch or button 17 which is configured to activate the device. 1 for vapour generation after the cover member 6 has been moved to the second or “in-use” position B. The front panel 6′ may also include one or more further switch or button 21 which may be positioned on a surface thereof (e.g. discretely or clearly) for activating additional functionalities, such as for setting an operating mode. Each of the switches or buttons 17, 21 is in operative connection with a part of the controller or control unit 13 of the device 1 below the cover member 6, which is described later. When the cover member 6 is moved to the second position B, the indicator 17 may illuminate to identify that the device 1 has been activated and/or is ready for operation. Further, the indicator 20 may illuminate in a different colour and/or in a different manner (e.g. blink or pulsate) to signal to a user that the available power supply in the battery unit D is low (e.g. that the battery unit D should be recharged). For this purpose, the opposite end region 22 of the body 4 of the e-cigarette 1 typically includes a connector 23 for connection to a re-charging dock or re-charging station and/or for connection of a re-charging cable.


As is apparent from drawing FIG. 9, the underside of the front panel 6′ includes sleeve elements 24 for sliding engagement with parallel rail members 25 (seen in FIG. 10) on the body portion 4 during longitudinal movement between the first and second positions A, B. In this way, the rail members 25 function as guide means for guiding the longitudinal movement of the cover member 6 and sleeve elements 24 form follower elements for following the path defined by the rails. Further, referring to drawing FIG. 10, the elongate body portion 4 of the device 1 includes a circuit board (not shown) mounted below the front panel 6′ which forms part of the controller or control unit 13 of the e-cigarette.


Finally, referring to FIG. 11 of the drawings, a flow diagram is shown that illustrates schematically the steps in a method of installing a cartridge in a personal vaporizer device 1, especially in an electronic smoking article according to the embodiments of the invention described above with respect to FIGS. 1 to 10. In this regard, the first box i of FIG. 11 thus represents the step of providing a personal vaporizer device 1 having an elongate body portion 4 to which a removable cartridge 2 is configured to be connected, the cartridge 2 including a reservoir 8 for storing a liquid to be vaporized. The second box ii represents the step of providing a cover member 6 on the elongate body portion 4 which is movable in a longitudinal direction of the body portion 4 between a first extended position A and a second retracted position B. The third box Iii represents the step of moving cover member 6 to the second retracted position B to access an end region 3 of the body portion 4. The final box iv in FIG. 11 of the drawings represents the step of attaching the cartridge 2 to the accessed end region 3 of the body portion 4 personal vaporizer device 1.
