However, in some exemplary related arts, the aerosol generation apparatus usually has only one cartridge for storing the liquid preparation. A capacity and types of liquid substrates stored in the aerosol generation apparatus are limited due to limitation of a volume of a single cartridge, affecting user experience.

SUMMARY



[0003] An objective of this application is to provide an aerosol generation apparatus with a large capacity for storing liquid substrates.

[0004] An embodiment of this application provides an aerosol generation apparatus, including:

a cartridge assembly, including a plurality of cartridges, each of the cartridges having an accommodating cavity for accommodating a liquid substrate, an atomizer for atomizing the liquid substrate, and a first electrode group electrically connected to the atomizer; and

a power supply assembly, rotatably connected to the cartridge assembly, the power supply assembly including a second electrode group, the second electrode group being configured to be electrically connected to the first electrode group in any of the cartridges during rotation, where

there is an interlocking mechanism between the cartridge assembly and the power supply assembly, and the interlocking mechanism is configured to prevent the cartridge assembly from rotating relative to the power supply assembly.



[0005] In an example, the interlocking mechanism includes a first locking member arranged on the cartridge assembly and a second locking member arranged on the power supply assembly, and the first locking member is capable of being fitted with the second locking member to prevent the cartridge assembly and the power supply assembly from rotating relative to each other.

[0006] In an example, the first locking member is configured to be slidable relative to the second locking member, and a direction in which the first locking member slides relative to the second locking member is substantially parallel to an axis in which the cartridge assembly rotates relative to the power supply assembly.

[0007] In an example, the cartridge assembly is configured to be slidable relative to the power supply assembly, and a direction in which the cartridge assembly slides relative to the power supply assembly is substantially parallel to an axis in which the cartridge assembly rotates relative to the power supply assembly.

[0008] In an example, the power supply assembly includes a first limiting member and a second limiting member, and a slide stroke of the cartridge assembly is provided between the first limiting member and the second limiting member.

[0009] In an example, the cartridge assembly slides relative to the power supply assembly and between a first position and a second position, the interlocking mechanism is locked when the cartridge assembly is at the first position, and the interlocking mechanism is unlocked when the cartridge assembly is at the second position.

[0010] In an example, the aerosol generation apparatus further includes a holding mechanism, the holding mechanism is connected to the cartridge assembly and the power supply assembly, the cartridge assembly is configured to be slidable along the power supply assembly and between the first position and the second position, and the holding mechanism is configured to provide resistance for the cartridge assembly to slide from the first position to the second position.

[0011] In an example, the holding mechanism includes an elastic member or a magnetic assembly.

[0012] In an example, a receiving mechanism is arranged at a center of a cross section of one of the cartridge assembly and the power supply assembly, an insertion mechanism is arranged at a center of a cross section of the other one, the insertion mechanism is at least partially arranged in a receiving hole of the receiving mechanism in a rotatable manner, the insertion mechanism is configured to be movable along a central axis of the receiving hole, and a direction in which the insertion mechanism moves along the central axis is consistent with the direction in which the cartridge assembly slides relative to the power supply assembly; and
the holding mechanism is connected to the insertion mechanism and the receiving mechanism.

[0013] In an example, the receiving mechanism has a holding cavity, a stopper is arranged on the insertion mechanism, the stopper supports the holding mechanism to hold the holding mechanism in the holding cavity, and the stopper is configured to be rotatable relative to the holding mechanism.

[0014] In an example, a stopper is arranged on the insertion mechanism, and an outer diameter of the stopper is greater than an aperture of at least a part of the receiving hole (B5), to prevent the insertion mechanism from disengaging from the receiving hole (B5).

[0015] In an example, the aerosol generation apparatus further includes an anti-collision member, and the anti-collision member is configured to elastically abut against the cartridge assembly and/or the power supply assembly when the cartridge assembly is at the first position.

[0016] In an example, each of the cartridges has a first air passage in fluid communication with the atomizer; and
the aerosol generation apparatus further includes a nozzle member, and the nozzle member is configured to be rotatably connected to the cartridge assembly, so that the nozzle member rotates relative to the cartridge assembly to be in fluid communication with a first air passage in one of the cartridges.

[0017] In an example, each of the cartridges has a first air passage in fluid communication with the atomizer; and
the aerosol generation apparatus further includes a nozzle member, and the nozzle member is simultaneously in fluid communication with first air passages in the cartridges.

[0018] The aerosol generation apparatus has a cartridge assembly including a plurality of cartridges. Each of the cartridges has an accommodating cavity for accommodating a liquid substrate and an atomizer for atomizing the liquid substrate. The power supply assembly is rotatably connected to the cartridge assembly, and the power supply assembly and the cartridge assembly rotate relative to each other to enable the second electrode group to be electrically connected to the first electrode group that abuts against the second electrode group. In this way, an atomizer in one of the cartridges can draw power from the power supply assembly to atomize the liquid substrate. Therefore, the power supply assembly is enabled to rotate relative to the cartridge assembly, to select a cartridge electrically connected to the second electrode group, which breaks volume limitation of a single cartridge without switching different cartridges by detaching the cartridge. This improves user experience and increases convenience in use while facilitates an increase in the capacity for storing liquid substrates. In addition, the interlocking mechanism can prevent the cartridge assembly from rotating relative to the power supply assembly, which helps to ensure that a stable electrical connection is maintained between the second electrode group and the first electrode group that abuts against the second electrode group.

Apparently, the described embodiments are some rather than all of the embodiments of this application. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of this application without creative efforts shall fall within the protection scope of this application.

[0022] The terms "first", "second", and "third" in this application are merely for the purpose of description, and shall not be construed as an indication or implication of relative importance or an implicit indication of a quantity or an order of indicated technical features. All directional indications (such as up, down, left, right, front, back...) in the embodiments of this application are only used to explain relative position relations, movement situation, or the like between components under a certain posture (as shown in the accompanying drawings). If the certain posture changes, the directional indication also changes accordingly. In addition, the terms "include", "have", and any variant thereof are intended to cover a non-exclusive inclusion.

The term appearing at different positions of the specification may not refer to the same embodiment or an independent or alternative embodiment that is mutually exclusive with another embodiment. A person skilled in the art explicitly or implicitly understands that the embodiments described in the specification may be combined with other embodiments.

[0024] It is to be noted that, when a component is referred to as "being fixed to" another component, the component may be directly on the other component, or an intervening component may be present. When an element is considered to be "connected to" another element, the element may be directly connected to the another element, or one or more intervening elements may be also present. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this specification are merely for purposes of illustration but not indicate a unique implementation.

[0025] Refer to FIG. 1 and FIG. 3. An embodiment of this application provides an aerosol generation apparatus. The aerosol generation apparatus includes a housing 2 and a cartridge assembly A including a plurality of cartridges 1. Each cartridge 1 may have an accommodating cavity 11. The accommodating cavity 11 is configured to accommodate a liquid substrate that can be atomized to generate an aerosol. A volume of each accommodating cavity 11 is not greater than 5 ml. Each cartridge 1 may further include an atomizer 12. The atomizer 12 is in fluid communication with the accommodating cavity 11, and the atomizer 12 is configured to atomize the liquid substrate to generate an aerosol.

[0026] The plurality of cartridges 1 may be held in the housing 2 parallel to each other. The "plurality of" means two or more. In an embodiment shown in FIG. 3, there are 4 cartridges 1, but not limited thereto. At least two cartridges 1 in the plurality of cartridges 1 may be configured to accommodate different liquid substrates, where the different liquid substrates include liquid substrates of different tastes or liquid substrates with different compositions and ratios. In this way, a user may be provided with aerosols having different sensory experience by operating atomizers in different cartridges 1 or simultaneously operating a plurality of atomizers 12, to provide the user with aerosols mixed in a predetermined ratio. Certainly, in an embodiment, liquid substrates accommodated in all cartridges 1 may be the same.

[0027] The liquid substrate may include a liquid including a tobacco-containing substance having a volatile tobacco-flavor component, and may further include a liquid including a non-tobacco substance. The liquid substrate may include water, a medicinal solution, a solvent, ethanol, a plant extract, a spice, a fragrance, a vitamin mixture, or the like. The spice may include an areca extract, menthol, peppermint, green mint oil, and various fruit flavor ingredients, but is not limited thereto. The fragrance may include ingredients that can provide various scents or flavors to the user. The vitamin mixture may be a mixture mixed with at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but is not limited thereto. Based on different properties of the liquid substrate, the aerosol generation apparatus may be used in different fields, such as medical treatment, electronic aerosol atomization, and the like.

[0028] The housing 2 arranged around the plurality of cartridges 1 may be at least partially transparent, so that the cartridges 1 in the housing can be visually observed through the housing 2. A wall that is in the cartridge 1 and that is used for defining the accommodating cavity 11 may also be at least partially transparent, so that an interior of the cartridge 1 may be visually observed respectively through the housing 2 and the wall defining the accommodating cavity 11, for example, a remaining amount of liquid substrates in the cartridge 1 is observed to provide the basis for the user to switch the cartridge 1.

[0029] The atomizer 12 may include a liquid absorbing element and a heating element. The liquid absorbing element may be a porous body or fibers, and can absorb a liquid substrate and guide the liquid substrate into an atomization range of the heating element. The heating element is configured to atomize at least some liquid substrates on the liquid absorbing element, to generate an aerosol. The heating element may be integrated on the liquid absorbing element, so that the heating element and the liquid absorbing element can be formed as a whole.

[0030] Each of the cartridges 1 may further include a first air passage 13. The first air passage 13 is in fluid communication with the atomizer 12, and the first air passage 13 is configured to deliver an aerosol. In an example, the cartridge 1 may have an atomization compartment in fluid communication with the accommodating cavity 11, the atomizer 12 is accommodated in the atomization compartment, and a first air passage 13 is in fluid communication with the atomization compartment. Alternatively, in another example, the atomizer 12 is at least partially arranged in the first air passage 13.

[0031] The aerosol generation apparatus may further include a nozzle member 3. The nozzle member 3 is in fluid communication with a first air passage 13 of at least one cartridge 1, and the nozzle member 3 can be at least partially held in the mouth, so that the user may inhale an aerosol by inhaling the nozzle member 3.

[0032] Refer to FIG. 1 and FIG. 2. The aerosol generation apparatus further includes a power supply assembly B. The cartridge assembly A is rotatably connected to the power supply assembly B. In this way, based on relative rotation between the cartridge assembly A and the power supply assembly B, the power supply assembly B is enabled to provide power to atomizers in different cartridges 1 in the cartridge assembly A, to select an atomizer 12 in at least one cartridge 1 for operation, thereby providing an aerosol to the user.

[0033] Based on this, referring to FIG. 1, the cartridge assembly A further includes a plurality of first electrode groups 4. A quantity of first electrode groups 4 may be consistent with a quantity of atomizers 12. An atomizer 12 in each cartridge 1 is exclusively electrically connected to one of the first electrode groups 4. In other words, one atomizer 12 is electrically connected to only one first electrode group 4, and one first electrode group 4 is electrically connected to only one atomizer 12, so that the plurality of atomizers 12 are electrically connected to different first electrode groups 4 respectively. The atomizer 12 can draw power from the first electrode group 4 electrically connected to the atomizer, to atomize a liquid substrate in a corresponding accommodating cavity. The first electrode group 4 may be a component in a corresponding cartridge 1. The first electrode group 4 may be arranged at a far end (that is, on a bottom portion) of the corresponding cartridge 1.

[0034] The power supply assembly B includes second electrode groups 5. A quantity of second electrode groups 5 is less than the quantity of first electrode groups 4. When the cartridge assembly A rotates relative to the power supply assembly B, the first electrode group 4 rotates relative to the second electrode group 5, and at least one second electrode group 5 may be configured to electrically abut against different first electrode groups 4 in turn when the cartridge assembly A rotates relative to the power supply assembly B.

[0035] In an embodiment, referring to FIG. 2, there is only one second electrode group 5. The second electrode group 5 is configured to be electrically connected to the first electrode group 4 that rotates and abuts against the second electrode group, so that the power supply assembly B can only supply power to an atomizer 12 of one of the cartridges 1 at a same moment, so that only one cartridge 1 can generate an aerosol at the same moment.

[0036] Based on this, in an example, referring to FIG. 4 and FIG. 6, the nozzle member 3 may be simultaneously in fluid communication with first air passages 13 in the plurality of cartridges 1, so that an aerosol generated by any cartridge can be delivered to the nozzle member 3 through a first air passage 13 of the cartridge 1. Alternatively, in an example, referring to FIG. 5, the nozzle member 3 is configured to be rotatable relative to the cartridge assembly A, so that based on relative rotation between the nozzle member 3 and the cartridge assembly A, the nozzle member 3 is enabled to be in fluid communication with a first air passage 13 of one of the cartridges 1 at a same moment. In addition, a first electrode group 4 corresponding to the cartridge 1 in fluid communication with the nozzle member 3 is electrically connected to the second electrode group 5 at the same moment. In this way, a cartridge 1 only electrically connected to the second electrode group 5 at the same moment can generate an aerosol, and a first air passage 13 of the cartridge 1 can be in fluid communication with the nozzle member 3.

[0037] In an embodiment shown in FIG. 5, the aerosol generation apparatus further includes an elastic body 6 and an end cap 7. The end cap 7 is connected to a near end of the housing 2, the nozzle member 3 is rotatably connected to the end cap 7, and the nozzle member 3 rotates relative to the end cap 7 to rotate relative to the cartridge assembly A. The end cap 7 has a plurality of second air passages 71. Each second air passage 7 is exclusively in fluid communication with one first air passage 13, the elastic body 6 is at least partially arranged between the end cap 7 and a nozzle member 3, and the elastic body 6 may be configured to provide resistance on rotation between the nozzle member 3 and end cap 7, to prevent the nozzle member 3 from rotating relative to the end cap 7 when rotation relative to the end cap 7 is not necessary. The end cap 7 may have a groove. The elastic body 6 may be at least partially accommodated in the groove, and a through hole 61 for a second channel 71 to pass through is provided on the elastic body 6. The elastic body 6 may be fitted with the end cap 7 through the through hole 61, to be unable to rotate relative to the end cap 7. The elastic body 6 may have an annular convex rib 62 surrounding the through hole 61. The annular convex rib 62 elastically abuts against the nozzle member 3, the annular convex rib 62 is configured to air-tightly isolate a second channel 71 and the through hole 61 surrounded by the through hole from another through hole 61 and second channel 71. In addition, the annular convex rib 62 rubs the nozzle member 3 when the nozzle member 3 rotates relative to the end cap 7, to prevent the nozzle member 3 from rotating relative to the end cap 7.

[0038] It is to be noted that, in other examples, there may be a plurality of second electrode groups, and the nozzle member may also be simultaneously in fluid communication with first air passages in the plurality of cartridges, so that the power supply assembly may simultaneously supply power to atomizers in the plurality of cartridges, and the user can simultaneously inhale, through the nozzle member, aerosols generated by the plurality of cartridges. For example, when there are two second electrode groups, the two second electrode groups may respectively electrically abut against two first electrode groups, so that the power supply assembly simultaneously supplies power to atomizers in two cartridges. In this example, the nozzle member can be simultaneously in fluid communication with first air passages of the two cartridges, so that the user can simultaneously inhale, through the nozzle member, aerosols generated by the two cartridges.

[0039] The first electrode group 4 and the second electrode group 5 may each include at least two electrodes, where the electrodes may be, for example, an anode electrode and a cathode electrode respectively.

[0040] The power supply assembly B may include any suitable battery core 8. In an embodiment, the battery core 8 is a lithium ion battery. Alternatively, the battery core 8 may be a nickel metal hydride battery, a nickel-cadmium battery, or a lithium-based battery, for example, a lithium cobalt battery, a lithium iron phosphate lithium cobalt battery, a lithium titanate lithium cobalt battery, or a lithium polymer battery. The power supply assembly B may include a circuit board and one or more control circuits arranged on the circuit board. The control circuit may control output of the battery core 8, for example, enabling the battery core 8 to output an alternating current or a direct current, or for example, enabling the battery core 8 to output current or voltage in a form of pulses.

[0041] The control circuit may have one or more controllers thereon. The controller may control overall operations by the aerosol generation apparatus. To be specific, the controller not only controls operations by the battery core and the cartridge, but also controls an operation by another element in the aerosol generation apparatus. In addition, the controller may determine whether the aerosol generation apparatus is operable by checking a status of an element of the aerosol generation apparatus.

[0042] The aerosol generation apparatus may further include a control switch. After at least one second electrode group electrically abuts against at least one first electrode group, the power supply assembly may be controlled, through the control switch, to provide voltage, current, or electric power to a corresponding first electrode group through the second electrode group.

[0043] There is an interlocking mechanism between the cartridge assembly A and the power supply assembly B. The interlocking mechanism is configured to prevent the cartridge assembly A from rotating relative to the power supply assembly B. The interlocking mechanism may ensure that a selected cartridge 1 maintains a stable electrical connection to the power supply assembly B, to avoid a sudden open circuit between the corresponding cartridge 1 and the power supply assembly B during use of the aerosol generation apparatus. In addition, the interlocking mechanism may prevent the aerosol generation apparatus from being used by inappropriate people, such as children or elderly people.

[0044] The interlocking mechanism may include a first locking member A1 arranged on the cartridge assembly A and a second locking member B 1 arranged on the power supply assembly B. In an embodiment, the first locking member A1 and the second locking member B1 are magnetically attractable to each other, to prevent, based on magnetic attraction, the cartridge assembly A from rotating relative to the power supply assembly B. In an embodiment, when the first locking member A1 and the second locking member B 1 are fitted with each other, for example, when at least one of the first locking member A1 and the second locking member B 1 at least partially enters the other one, the interlocking mechanism is locked, so that the cartridge assembly A cannot rotate relative to the power supply assembly B. When the first locking member A1 and the second locking member B 1 are separated from each other, the interlocking mechanism is unlocked, so that the cartridge assembly A can rotate relative to the power supply assembly B, to further select and switch a first electrode group 4 that electrically abuts against the power supply assembly B.

[0045] When the interlocking mechanism is locked by fitting the first locking member A1 with the second locking member B 1, in an embodiment, referring to FIG. 1, the first locking member A1 is configured to be slidable relative to the second locking member B 1, and a direction in which the first locking member A1 slides relative to the second locking member B 1 is perpendicular to a direction in which the cartridge assembly A rotates relative to the power supply assembly B, or a direction in which the first locking member A1 slides relative to the second locking member B 1 is substantially parallel to an axis in which the cartridge assembly A rotates relative to the power supply assembly B.

[0046] Based on this, in an example, when the first locking member slides relative to the second locking member, the first locking member can also slide relative to other parts of the cartridge assembly, such as the cartridge, the first electrode group, or the housing, so that when the first locking member slides relative to the second locking member, the other parts of the cartridge assembly may remain static relative to the power supply assembly. Alternatively, when the first locking member slides relative to the second locking member, the second electrode group may maintain an electrical connection with a selected first electrode group until the interlocking mechanism is unlocked and the cartridge assembly rotates relative to the power supply assembly by an angle, and the second electrode group may disconnect the electrical connection with the selected first electrode assembly. In an example, when the second locking member slides relative to the first locking member, the second locking member can also slide relative to other parts of the power supply assembly, such as the battery core or the second electrode group, so that when the first locking member slides relative to the second locking member, the other parts of the power supply assembly may remain static relative to the cartridge assembly. Alternatively, when the first locking member slides relative to the second locking member, the second electrode group may maintain an electrical connection with a selected first electrode assembly.

[0047] Alternatively, in another example, referring to FIG. 1 and FIG. 2, when the first locking member A1 slides relative to the second locking member B 1, the cartridge assembly A slides relative to the power supply assembly B, and the direction in which the first locking member A1 slides relative to the second locking member B1 is perpendicular to the direction in which the cartridge assembly A rotates relative to the power supply assembly B, or the direction in which the first locking member A1 slides relative to the second locking member B 1 is substantially parallel to the axis in which the cartridge assembly A rotates relative to the power supply assembly B.

[0048] The interlocking mechanism may be unlocked when the cartridge assembly A slides along the power supply assembly B to a third position. In other words, when the cartridge assembly A slides along the power supply assembly B to the third position, the first locking member A1 and the second locking member B 1 are separated from each other, so that the cartridge assembly A may rotate relative to the power supply assembly B.

[0049] Referring to FIG. 3, the power supply assembly B includes a bracket B2. The second electrode group5 may be fixed to the bracket B2, a docking cavity is defined between the cartridge assembly A and a far end of the housing 2, and the first electrode group 4 is at least partially exposed in the docking cavity, so that when the bracket B2 is at least partially inserted into the docking cavity, at least one first electrode group 4 can abut against the second electrode group 5. A near end that is of the housing 2 and that is opposite to the far end is connected to the nozzle member 3 or close to the nozzle member 3.

[0050] A slider is arranged on one of the far end of the housing 2 and the bracket B2, and a sliding groove is provided on the other one. The slider is slidably connected to the sliding groove, that is, one of the first locking member A1 and the second locking member B 1 may be a slider, and the other one may be a sliding groove. The interlocking mechanism is locked when the slider is connected to the sliding groove, and the interlocking mechanism is unlocked when the slider is disengaged from the sliding groove. More specifically, the slider and the sliding groove are separated from each other when the cartridge assembly A slides along the power supply assembly B to the third position.

[0051] The cartridge assembly A is configured to be slidable along the power supply assembly B between the first position and the second position, that is, the cartridge assembly A may remain connected to the power supply assembly B between the first position and the second position. The second electrode group 5 electrically abuts against the selected first electrode group 4 when the cartridge assembly A is at the first position.

[0052] To prevent the cartridge assembly A from continuing to slide in an original sliding direction after sliding along the power supply assembly B to the second position. Referring to FIG. 6, the power supply assembly B may include a first limiting member B3. The first limiting member B3 is configured to abut against the cartridge assembly A when the cartridge assembly A slides along the power supply assembly B to the second position, to prevent the cartridge assembly A from being separated from the power supply assembly B.

[0053] Referring to FIG. 6, the power supply assembly B may include a second limiting member B4. The second limiting member B4 is configured to support the cartridge assembly A when the cartridge assembly A slides along the power supply assembly B to the first position, to prevent the cartridge assembly A from continuing to slide in the original sliding direction after sliding along the power supply assembly B to the first position, thereby preventing the second electrode group 5 from excessively squeezing the selected first electrode group 4.

[0054] The third position may be located between the first position and the second position. In other words, after the cartridge assembly A slides along the power supply assembly B from the first position to the third position to enable the interlocking mechanism to be unlocked, the cartridge assembly A may further be enabled to continue to slide in the original sliding direction until sliding to the second position. Certainly, in some embodiments, the third position is the second position, that is, the third position overlaps the second position.

[0055] On the basis that the interlocking mechanism is unlocked when the cartridge assembly A slides along the power supply assembly B to the third position, referring to FIG. 6, the aerosol generation apparatus may further include a holding mechanism 9. The holding mechanism 9 is connected to the cartridge assembly A and the power supply assembly B. The holding mechanism 9 is configured to provide resistance for the cartridge assembly A to slide from the first position to the second position. In other words, the holding mechanism 9 helps to hold the cartridge assembly A at the first position, or helps the cartridge assembly A at the third position or the second position return to the first position. The holding mechanism 9 may ensure that the interlocking mechanism can remain locked, to prevent the interlocking mechanism from being unlocked when not necessary, and may ensure that the second electrode group 5 of the power supply assembly B can remain a stable electrical connection to the selected first electrode group 4.

[0056] More specifically, in an example, referring to FIG. 1, FIG. 2, and FIG. 6, a receiving mechanism is arranged at a center of a cross section of one of the cartridge assembly A and the power supply assembly B, and an insertion mechanism is arranged at a center of a cross section of the other, the insertion mechanism is at least partially arranged in a receiving hole B5 of the receiving mechanism in a rotatable manner, 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 is consistent with the direction in which the cartridge assembly A slides relative to the power supply assembly B. The holding mechanism 9 is connected to the insertion mechanism and the receiving mechanism B5.

[0057] The receiving mechanism has a holding cavity. The insertion mechanism includes an insertion member A2 and a stopper A3 connected to the insertion member A2. At least a part of the insertion member A2 is located in the receiving hole B5 and is 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. The stopper A3 may be located in the holding cavity, and when the cartridge assembly A slides along the power supply assembly B and between the first position and the second position, the stopper A3 may be located in the holding cavity and move up and down in the holding cavity. An outer diameter of the stopper A3 (that is, a maximum distance between an outer contour and a central axis of the stopper) may be greater than an aperture of at least a part of the receiving hole B5, to prevent the insertion mechanism from disengaging from the receiving hole B5. The stopper A3 may abut against the first limiting member B3 when the cartridge assembly A slides along the power supply assembly B to the second position, to prevent the cartridge assembly A from being separated from the power supply assembly B.

[0058] More specifically, the cartridge assembly A includes the insertion mechanism, and the power supply assembly B includes the receiving mechanism.

[0059] The housing 2 of the cartridge assembly A has a bottom plate 21. The bottom plate 21 is configured to support a plurality of cartridges 1, to hold the plurality of cartridges 1 in the housing 2. The bottom plate 21 has a plurality of mounting holes, each mounting hole is embedded by a far end of at least one cartridge 1, and the first electrode group 4 may be exposed through a corresponding mounting hole. The insertion mechanism is connected to the bottom plate 21, the insertion mechanism is at least partially located in the docking cavity, and the insertion mechanism may be located at a center of a cross section of the bottom plate 21. The housing 2, the bottom plate 21, and the insertion member A2 of the insertion mechanism may be integrally formed through injection molding.

[0060] The receiving mechanism may be formed on a part of the bracket B2. The bracket B2 includes a support plate B21. At least a part of the support plate B21 defines a boundary of a near end of the holding cavity. The receiving hole B5 penetrates the support plate B21 and is located at a center of the bracket B2. The second electrode group 5 is fixed to the support plate B21.

[0061] The holding mechanism 9 may be an elastic member, for example, a spiral spring. The elastic member may surround a periphery of the insertion member A2. A near end and a far end of the elastic member may respectively abut against the support plate B21 and a stopper A3. When the cartridge assembly A is at the first position, the elastic member is in an elastic compression state and has first elastic potential energy. When the cartridge assembly A is at the second position, the elastic member is in an elastic compression state and has second elastic potential energy. An elastic force provided by the first elastic potential energy is used for holding the cartridge assembly A at the first position and preventing the cartridge assembly A from sliding to the second position. The second elastic potential energy is greater than the first elastic potential energy.

[0062] Alternatively, the holding mechanism may be a magnetic assembly. For example, the holding mechanism includes a first magnetic member and a second magnetic member. The first magnetic member is arranged on the support plate, the second magnetic member is arranged on the stopper. The first magnetic member and the second magnetic member repel each other, and a repulsive force between the first magnetic member and the second magnetic member when the cartridge assembly is at the first position is less than a repulsive force when the cartridge assembly is at the second position.

[0063] In an embodiment, referring to FIG. 2 and FIG. 6, the aerosol generation apparatus may further include an anti-collision member B6. The anti-collision member B6 is configured to elastically abut against the cartridge assembly A and/or the power supply assembly B when the cartridge assembly A is at the first position. Specifically, the anti-collision member B6 may be arranged between the bottom plate 21 of the cartridge assembly A and the support plate B21 of the power supply assembly B. The anti-collision member B6 may have a through hole, and the second electrode group5 may penetrate the through hole. More specifically, the anti-collision member B6 may be fixed to the bracket B2.
