Each cartridge 1 may further comprise an atomizer 12, the atomizers 12 being in fluid communication with the receiving chamber 11, and the atomizers 12 being adapted to atomize the liquid matrix to produce an aerosol.

The plurality of clips 1 described above may be held in parallel with each other in the housing 2, and the term "plurality" refers to two or more, and in the embodiment shown in fig. 3, the number of clips 1 is 4, but not limited to this. At least two of the plurality of cartridges 1 may be used to hold different liquid matrices, including different flavours or different compositions, proportions of liquid matrices, so that aerosols with different sensory experiences may be provided to a user by operating the atomizers in different cartridges 1, or multiple atomizers 12 may be operated simultaneously to provide aerosols mixed in a preset ratio to a user. Of course, in one embodiment, all cartridges 1 may contain the same liquid matrix.

The atomizer 12 may include a wick and a heat generating element, the wick may be a porous body or fiber capable of absorbing a liquid matrix and of directing the liquid matrix into an atomization zone of the heat generating element; the heating element is used for atomizing at least part of the liquid matrix on the liquid absorbing element to form aerosol. The heating element may be bonded to the wicking element such that the heating element can be integral with the heating element.

Each cartridge 1 described above may further comprise a first air passage 13, the first air passage 13 being in fluid communication with the atomizer 12, the first air passage 13 being adapted to deliver aerosol. In one example, the cartridge 1 may have an aerosolization compartment therein in fluid communication with the receiving cavity 11, the aerosolizer 12 being received in the aerosolization compartment, and the first channel 22 being in fluid communication with the aerosolization compartment; alternatively, in another example, at least a portion of the atomizer 12 is disposed in the first passage 22.

The aerosol-generating device may further comprise a mouthpiece 3, the mouthpiece 3 being in fluid communication with the first air passage 13 in at least one of the cartridges 1, and at least part of the mouthpiece 3 being adapted to be mouthpiece by a user so that the user may draw aerosol through the mouthpiece 3.

Referring to fig. 1 and 2, the aerosol-generating device further comprises a power supply assembly B, to which the cartridge clip assembly a is rotatably connected, for providing power to the atomizers in the different cartridges 1 in the cartridge clip assembly a by the relative rotation of the cartridge clip assembly a and the power supply assembly B, so as to selectively operate the atomizers 12 in at least one of the cartridges 1 to provide the aerosol to the user.

Based on this, referring to fig. 1, the cartridge clip assembly a further includes a plurality of first electrode sets 4, the number of the first electrode sets 4 may be identical to the number of the atomizers 12, and each atomizer 12 in each cartridge clip 1 is electrically connected with one of the first electrode sets 4 exclusively, that is, one atomizer 12 is electrically connected with only one first electrode set 4, and at the same time, one first electrode set 4 is electrically connected with only one atomizer 12, such that the plurality of atomizers 12 are electrically connected with different first electrode sets 4 respectively. The atomizer 12 is capable of applying electricity from the first electrode set 4 electrically connected thereto to atomize the liquid matrix in the corresponding receiving chamber. The first electrode group 4 may be an integral part of the cartridge 1 corresponding thereto, and the first electrode group 4 may be disposed at the distal end (i.e., bottom) of the cartridge 1 corresponding thereto.

The power supply assembly B includes second electrode sets 5, the number of second electrode sets 5 is less than the number of first electrode sets 4, the first electrode sets 4 rotate relative to the second electrode sets 5 when the cartridge clip assembly a rotates relative to the power supply assembly B, and at least one second electrode set 5 may be configured to alternately electrically abut different first electrode sets 4 during rotation of the cartridge clip assembly a relative to the power supply assembly B.

In an embodiment, which may be seen in fig. 2, the second electrode set 5 has and only has one, the second electrode set 5 being configured to be in electrical communication with the first electrode set 4 rotated into abutment therewith, so that the power supply assembly B can only power the atomizer 12 of one of the cartridges 1 at the same time, so that only one cartridge 1 can generate aerosol at the same time.

Based thereon, in one example, referring to fig. 4 and 6, the mouthpiece 3 may be in simultaneous fluid communication with the first air passages 13 in a plurality of cartridges 1 such that the aerosol generated by either cartridge can be delivered to the mouthpiece 3 by the first air passages 13 in that cartridge 1. Alternatively, in an example, referring to fig. 5, the mouthpiece 3 may be configured to be rotatable relative to the cartridge assembly a, with the intention that the mouthpiece 3 may only be in fluid communication with the first air passageway 13 in one of the cartridges 1 at the same time by the relative rotation of the mouthpiece 3 and the cartridge assembly a, and the corresponding first electrode set 4 of the cartridge 1 in fluid communication with the mouthpiece 3 may be in electrical abutment with the second electrode set 5 at the same time, such that only the cartridge 1 electrically connected to the second electrode set 5 at the same time may be capable of generating aerosols and only the first air passageway 13 of the cartridge 1 may be in fluid communication with the mouthpiece 3.

In the embodiment shown in fig. 5, the aerosol-generating device further comprises an elastomer 6 and an end cap 7, the end cap 7 being connected to the proximal end of the housing 2, the mouthpiece 3 being rotatably connected to the end cap 7, the mouthpiece 3 being rotatable relative to the cartridge assembly a by rotation relative to the end cap 7. The end cap 7 has a plurality of second air passages 71 therein, each second air passage 7 being in exclusive fluid communication with a first air passage 13, at least a portion of the elastomer 6 being disposed between the end cap 7 and the mouthpiece 1, the elastomer 6 being operable to provide resistance to rotation of the mouthpiece 1 relative to the end cap 7 to prevent rotation of the mouthpiece 1 relative to the end cap 7 when rotation relative to the end cap 7 is not required. The end cover 7 may have a groove therein, at least a part of the elastic body 6 may be accommodated in the groove, and the elastic body 6 has a through hole 61 for the second channel 71 to pass through, and the elastic body 6 may be engaged with the end cover 7 through the through hole 61 so as not to be rotatable relative to the end cover 7. The elastic body 6 may have an annular rib 62 surrounding the through hole 61, the annular rib 62 elastically abutting against the mouthpiece 3, the annular rib 62 serving to hermetically isolate the through hole 61 and the second passage 71 surrounded by it from other through holes 61 and the second passage 71, while the annular rib 62 rubs against the mouthpiece 3 when the mouthpiece 3 rotates relative to the end cap 7 to hinder the mouthpiece 3 from rotating relative to the end cap 7.

It should be noted that, in other examples, the second electrode set may have a plurality of the second electrode sets, and the mouthpiece may be in fluid communication with the first air passages of the plurality of cartridges at the same time, so that the power supply assembly may be capable of simultaneously supplying electric power to the atomizers of the plurality of cartridges, and the user may be capable of simultaneously sucking the aerosols supplied from the plurality of cartridges from the mouthpiece; for example, where the second electrode sets have two, then the two second electrode sets may be respectively electrically abutted against the two first electrode sets such that the power assembly simultaneously provides power to the atomizers in the two cartridges, in this example, the mouthpiece can be in fluid communication with the first passages of the two cartridges simultaneously so that a user can simultaneously aspirate aerosols generated by the two cartridges from the mouthpiece.

The first electrode group 4 and the second electrode group 5 each include at least two electrodes, and may be, for example, an anode electrode and a cathode electrode, respectively.

The power supply assembly B may include any suitable battery cells 8. In one embodiment, the cell 8 is a lithium ion battery. Alternatively, the cell 8 may be a nickel metal hydride battery, nickel cadmium battery, or a lithium-based battery, such as a lithium cobalt, lithium iron phosphate, lithium titanate, or lithium polymer battery. The power supply assembly B may include a circuit board and one or more control circuits disposed on the circuit board, which may control the output of the battery cells 8, for example, to cause the battery cells 8 to output alternating current or direct current, or the like, or to cause the battery cells 8 to output current or voltage, or the like, in the form of pulses, for example.

The control circuit may have one or more controllers thereon. The controller may control the overall operation of the aerosol-generating device. In detail, the controller controls not only the operation of the battery cells and the cartridge, but also the operation of other elements in the aerosol-generating device. Furthermore, the controller may determine whether the aerosol-generating device is operable by checking the status of the elements of the aerosol-generating device.

The aerosol-generating device may further comprise a control switch, and the control switch may be used to control the power supply assembly to supply voltage, current or electric power to the corresponding first motor set via the second electrode set after the at least one second electrode set is electrically abutted to the at least one first electrode set.

There is an interlock mechanism between the clip assembly a and the power source assembly B that is configured to prevent rotation of the clip assembly a relative to the power source assembly B. The interlocking mechanism ensures that the selected cartridge 1 is electrically and stably connected to the power supply assembly B, and prevents the aerosol-generating device from being opened suddenly between the corresponding cartridge 1 and the power supply assembly B during use, and prevents the aerosol-generating device from being used by an improper population such as children or the elderly.

The interlock mechanism may include a first lock A1 provided on the cartridge clip assembly a and a second lock B1 provided on the power supply assembly B. In one embodiment, the first lock A1 and the second lock B1 are magnetically attractable to each other, with the aim of preventing the cartridge assembly a from being able to rotate relative to the power assembly B by their magnetic attraction to each other. In one embodiment, when the first lock A1 and the second lock B1 are engaged with each other, for example, when at least part of one of the first lock A1 and the second lock B1 is entered into the other, the interlock mechanism is locked so that the clip assembly a cannot rotate relative to the power source assembly B; when the first locking piece A1 and the second locking piece B1 are mutually separated, the interlocking mechanism is unlocked, so that the cartridge clip assembly A can rotate relative to the power assembly B, and further the first electrode group 4 electrically abutted to the power assembly B can be selected and switched.

When the interlocking mechanism is locked by the first lock member A1 and the second lock member B1 being engaged with each other, in an embodiment, referring to fig. 1, the first lock member A1 is configured to be slidable with respect to the second lock member B1, and the direction in which the first lock member A1 slides with respect to the second lock member B1 is perpendicular to the direction in which the cartridge clip assembly a rotates with respect to the power supply assembly B, or the direction in which the first lock member A1 slides with respect to the second lock member B1 is substantially parallel to the axis in which the cartridge clip assembly a rotates with respect to the power supply assembly B.

Based thereon, in one example, the first lock can also slide relative to other portions of the cartridge clip assembly, such as the cartridge clip, the first electrode set, or the housing, while the first lock slides relative to the second lock, such that other portions of the cartridge clip assembly can remain relatively stationary with the power supply assembly during the sliding of the first lock relative to the second lock; or, during the sliding of the first locking member relative to the second locking member, the second electrode set may remain in electrical contact with the selected first electrode assembly until the second electrode set is electrically disconnected from the selected first electrode assembly after the interlock mechanism is unlocked and the clip assembly is rotated relative to the power assembly by a certain angle. In one example, the second lock is also capable of sliding relative to other portions of the power assembly, such as the battery cell or the second electrode set, while the second lock slides relative to the first lock, such that other portions of the power assembly may remain relatively stationary with the cartridge assembly during sliding of the first lock relative to the second lock; alternatively, the second electrode set may be held in electrical abutment with the selected first electrode assembly during sliding movement of the first locking member relative to the second locking member.

Alternatively, in another example, referring to fig. 1 and 2, the first lock A1 slides relative to the second lock B1 while the clip assembly a slides relative to the power assembly B, and the direction in which the first lock A1 slides relative to the second lock B1 is perpendicular to the direction in which the clip assembly a rotates relative to the power assembly B, or the direction in which the first lock A1 slides relative to the second lock B1 is substantially parallel to the axis in which the clip assembly a rotates relative to the power assembly B.

The interlocking mechanism can be unlocked when the cartridge clip assembly a slides to the third position along the power supply assembly B, namely, when the cartridge clip assembly a slides to the third position along the power supply assembly B, the first locking piece A1 and the second locking piece B1 are separated from each other, so that the cartridge clip assembly a can rotate relative to the power supply assembly B.

Referring to fig. 3, the power supply assembly B includes a support B2, the second electrode assembly 5 may be fixed on the support B2, a docking cavity is defined at a distal end of the housing 2 of the cartridge clip assembly a, and at least a portion of the first electrode set 4 is exposed in the docking cavity, so that when the support B2 is partially inserted into the docking cavity, the at least one first electrode set 4 can abut against the second electrode set 5. Wherein the opposite proximal end of the housing 2 from its distal end is connected to the mouthpiece 3 or is close to the mouthpiece 3.

One of the distal end of the housing 2 and the bracket B2 may have a slider thereon, and the other may have a slide groove thereon, and the slider is slidably connected with the slide groove, that is, one of the first lock member A1 and the second lock member B1 may be the slider, and the other may be the slide groove. When the sliding block is connected with the sliding groove, the interlocking mechanism is locked, and when the sliding block is separated from the sliding groove, the interlocking mechanism is unlocked. More specifically, the slider and the chute are separated from each other when the clip assembly a is slid along the power assembly B to the third position.

Clip assembly a is configured to be slidable along power assembly B between a first position and a second position, i.e., clip assembly a may remain connected to power assembly B. When the cartridge clip assembly a is located at the first position, the second electrode assembly 5 is electrically abutted to the selected first electrode assembly 4.

In order to prevent the clip assembly a from sliding in the original sliding direction after sliding to the second position along the power assembly B, referring to fig. 6, the power assembly may include a first limiting member B3 thereon. The first limiting member B3 is configured to abut against the clip assembly a when the clip assembly a slides along the power assembly B to the second position, so as to prevent the clip assembly a from being separated from the power assembly B.

Referring to fig. 6, the power component B may include a second limiting member B4, where the second limiting member B4 is configured to support the clip component a when the clip component a slides along the power component B to the first position, so as to prevent the clip component a from sliding along the original sliding direction after sliding along the power component B to the first position, thereby preventing the second electrode component 5 from excessively pressing the selected first electrode component 4.

The third position may be located between the first position and the second position, that is, after the clip assembly a slides along the power assembly B from the first position to the third position so that the interlocking mechanism is unlocked, the clip assembly a may further slide along the original sliding direction until the clip assembly a slides to the second position. Of course, in some embodiments, the third position is the second position, that is, the third position coincides with the second position.

Based on the interlocking mechanism unlocking when the cartridge clip assembly a slides along the power supply assembly B to the third position, referring to fig. 6, the aerosol-generating device further comprises a holding mechanism 9, the holding mechanism 9 connecting the cartridge clip assembly a and the power supply assembly B, the holding mechanism 9 being configured to provide a resistance to sliding of the cartridge clip assembly a from the first position to the second position, i.e. the holding mechanism 9 is advantageous for holding the cartridge clip assembly a in the first position or for returning the cartridge clip assembly a in the third position or the second position to the first position. The holding means 9 on the one hand ensures that the interlocking means can remain locked, avoiding that the interlocking means are unlocked when not necessary, and on the other hand ensures that the second electrode set 5 of the power supply assembly B can remain stably electrically connected to the selected first motor set 4.

More specifically, in one example, referring to fig. 1, 2 and 6, a receiving mechanism is provided at a center of a cross section of one of the cartridge clip assembly a and the power supply assembly B, an insertion mechanism is provided at a center of a cross section of the other, at least a part of the insertion mechanism is rotatably disposed in a receiving hole B5 of the receiving mechanism, and the insertion mechanism is configured to be movable along a central axis of the receiving hole B5, and a direction in which the insertion mechanism moves along the central axis coincides with a direction in which the cartridge clip assembly a slides with respect to the power supply assembly B. The holding mechanism 9 connects the insertion mechanism and the receiving mechanism B5.

The insert A2 is at least partially located in the receiving hole B5 and rotatable in the receiving hole B5, the stopper A3 supports the holding mechanism 9 to hold the holding mechanism 9 in the holding cavity, and the stopper A3 is configured to be rotatable relative to the holding mechanism 9. Wherein the stop member A3 can be located in the holding cavity and the stop member A3 can both be located in the holding cavity and move up and down in the holding cavity as the clip assembly a slides along the power assembly B between the first and second positions. The outer diameter of the stop A3 (i.e. the maximum distance between its outer contour and its central axis) may be larger than the aperture of the receiving bore B5 at least partially to prevent the insertion mechanism from coming out of the receiving bore B5. When the clip assembly a slides along the power assembly B to the second position, the stopper A3 may abut against the first limiting member B3 to prevent the clip assembly a from being separated from the power assembly B.

More specifically, clip assembly a includes the insertion mechanism described above and power assembly B includes the receiving mechanism described above.

The holding means 9 may be an elastic member, such as a helical spring. The elastic member may surround the periphery of the insert A2. The proximal and distal ends of the elastic member may abut against the support plate B21 and the stopper plate A3, respectively. When the clip assembly A is located at the first position, the elastic piece is in an elastic compression state and has a first elastic potential energy, and when the clip assembly A is located at the second position, the elastic piece is in an elastic compression state and has a second elastic potential energy, wherein the elastic force provided by the first elastic potential energy is used for keeping the clip assembly A at the first position and preventing the clip assembly A from sliding towards the second position, and the second elastic potential energy is larger than the first elastic potential energy.
