[0031] Embodiments of this application provide an aerosol generating device, to generate aerosols for a user to inhale. Referring to FIG. 1 to FIG. 3, FIG. 14 to FIG. 16, FIG. 20 to FIG. 22, and FIG. 24 to FIG. 26, the aerosol generating device includes a functional assembly 10 and a power supply assembly 20.

[0032] The functional assembly 10 includes an additional e-liquid tank 40 and an atomizer 30, the additional e-liquid tank 40 is provided with an additional storage cavity 40a, the atomizer 30 is located on the side of the additional e-liquid tank 40 in a first direction, the atomizer 30 is provided with a main storage cavity 30a, and the main storage cavity 30a may be in communication with the additional storage cavity 40a.

[0033] The power supply assembly 20 is located on the side of the functional assembly 10 in a second direction, the first direction intersects the second direction, and the power supply assembly 20 is electrically connected to the atomizer 30.

[0034] The functional assembly 10 and the power supply assembly 20 are detachably connected.

[0035] The functional assembly 10 is a part of the aerosol generating device that may be configured to implement a function of converting an aerosol generating substrate into aerosols.

[0036] The additional storage cavity 40a is configured to store an aerosol generating substrate. The main storage cavity 30a is configured to store an aerosol generating substrate.

[0037] The atomizer 30 includes an atomization core 331, and the atomization core 331 is provided therein with an atomization cavity 331a. The main storage cavity 30a is isolated from the atomization cavity 331a. The atomization core 331 continuously converts the aerosol generating substrate in the main storage cavity 30a into aerosols. As the aerosols in the main storage cavity 30a are continuously consumed, the aerosol generating substrate in the additional storage cavity 40a can be continuously replenished to the main storage cavity 30a, thereby reducing problems such as dry heating of the atomization core 331 and increasing a service life of the aerosol generating device.

[0038] The power supply assembly 20 is configured to provide electric energy to the atomizer 30.

[0039] The atomizer 30 and the additional e-liquid tank 40 are arranged in the first direction, so that an aerosol generating substrate between the two mainly flows in the first direction.

[0040] It may be understood that the power supply assembly 20 includes various types of electronic components configured to implement normal operation of the atomizer 30. However, the aerosol generating substrate and condensates formed after condensation of the aerosols lead to problems such as a short circuit in the electronic components, and corrode the electronic components.

[0041] The power supply assembly 20 is located on the side of the functional assembly 10 in the second direction. That is, the atomizer 30, the additional e-liquid tank 40, and the power supply assembly 20 are not all arranged in the first direction. The above arrangement helps the power supply assembly 20 be away from the aerosol generating substrate flowing between the atomizer 30 and the additional e-liquid tank 40.

[0042] The functional assembly 10 and the power supply assembly 20 are detachably connected to each other. In this way, one of the two may be independently dismounted for service and replacement when damaged.

[0043] According to the aerosol generating device provided in the embodiments of this application, an arrangement direction of the functional assembly 10 and the power supply assembly 20 is different from an arrangement direction of the atomizer 30 and the additional e-liquid tank 40, which helps reduce a risk that liquids such as an aerosol generating substrate and condensates in the atomizer 30 and the additional e-liquid tank infiltrate the power supply assembly 20 and damage the electronic components in the power supply assembly 20, thereby increasing a service life of the power supply assembly 20.

[0044] In some embodiments, the first direction is perpendicular to the second direction, to help reduce an outer contour size of the aerosol generating device.

[0045] It may be understood that in a state in which the power supply assembly 20 and the functional assembly 10 are disassembled, the power supply assembly 20 is no longer electrically connected to the atomizer 30.

[0046] In some embodiments, the atomizer 30 is provided with an atomization cavity 331a, the functional assembly 10 is provided with an air outlet channel 10a, and outside of the aerosol generating device is in communication with the atomization cavity 331a through the air outlet channel 10a.

[0047] During inhalation of the aerosols by a user, the outlet of the air outlet channel 10a is configured to be in communication with an oral cavity of the user, so that the aerosols in the atomization cavity 331a enter the oral cavity of the user through the air outlet channel 10a.

[0048] In some embodiments, referring to FIG. 3 and FIG. 16, the additional e-liquid tank 40 is provided with an air outlet channel 10a, the air outlet channel 10a is in communication with the outside of the aerosol generating device, and the atomizer 30 is located on the side of the additional e-liquid tank 40 away from the outlet of the air outlet channel 10a in the first direction.

[0049] Providing the air outlet channel 10a through the additional e-liquid tank 40 helps lengthen an air flow path for aerosols discharged from the atomizer 30 to flow out of the aerosol generating device, which helps reduce a temperature of the aerosols to a suitable temperature range, thereby reducing problems such as mouth burning during use by the user. The additional e-liquid tank 40 may be replaced, to reduce hygiene risks to the user caused by hygiene issues such as bacterial growth in the air outlet channel 10a.

[0050] In some embodiments, referring to FIG. 26, the atomizer 30 is provided with an air outlet channel 10a, the air outlet channel 10a is in communication with the outside of the aerosol generating device, and the additional e-liquid tank 40 is located on the side of the atomizer 30 away from the outlet of the air outlet channel 10a in the first direction.

[0051] That is, the air outlet channel 10a does not run through the additional e-liquid tank 40.

[0052] The above arrangement helps increase a volume of the additional storage cavity 40a in a limited space, shorten a flow path of the aerosols, reduce a loss of the aerosols, reduce a probability that the aerosol generating substrate in the additional storage cavity 40a can always flow into the main storage cavity 30a, reduce a probability of supersaturation of the aerosol generating substrate in the main storage cavity 30a, and improve a taste of the aerosols.

[0053] In some embodiments, referring to FIG. 22, the atomizer 30 is provided with an air outlet channel 10a, the air outlet channel 10a is in communication with the outside of the aerosol generating device, and an extension direction of the air outlet channel 10a intersects the first direction. The above arrangement helps increase a volume of the additional storage cavity 40a in a limited space.

[0054] In some embodiments, the first direction substantially a vertical direction during use of the aerosol generating device by the user.

[0055] In some embodiments, referring to FIG. 9 and FIG. 18, one of the functional assembly 10 and the power supply assembly 20 is provided with an accommodating cavity 20a, and the accommodating cavity 20a is open in the second direction, for a part of the other of the functional assembly 10 and the power supply assembly 20 to enter the accommodating cavity 20a.

[0056] Because the inner wall of the accommodating cavity 20a can shield a detachable connection position and an electrical connection position between the functional assembly 10 and the power supply assembly 20, a risk of a connection failure and a risk of an electrical connection failure are reduced. A specific manner of implementing the detachable connection between the functional assembly 10 and the power supply assembly 20 is not limited.

[0057] In some embodiments, referring to FIG. 3, FIG. 8, and FIG. 9, the power supply assembly 20 includes a first attractive member 21, the atomizer 30 includes a second attractive member 31, and at least an attractive force in the second direction can be generated between the first attractive member 21 and the second attractive member 31.

[0058] Through the attractive force between the first attractive member 21 and the second attractive member 31, the power supply assembly 20 and the atomizer 30 can be attached to each other, thereby helping maintain the electrical connection state between the power supply assembly and the atomizer. The user applies an action force opposite the attractive force in the second direction to the power supply assembly 20 and the atomizer 30, which overcomes the attractive force, to separate the atomizer 30 from the power supply assembly 20, thereby achieving disassembly of the two. The operation is simple and convenient.

[0059] In some embodiments, referring to FIG. 3, FIG. 8, and FIG. 9, the additional e-liquid tank 40 includes a third attractive member 41, and at least an attractive force in the second direction can be generated between the first attractive member 21 and the third attractive member 41.

[0060] Though the attractive force between the first attractive member 21 and the third attractive member 41, the power supply assembly 20 can be attached to the functional assembly 10, thereby helping maintain the electrical connection state between the power supply assembly 20 and the atomizer 30. The user applies an action force opposite the attractive force in the second direction to the power supply assembly 20 and the atomizer 30, which overcomes the attractive force, to separate the atomizer 30 from the power supply assembly 20, thereby achieving disassembly of the two. The operation is simple and convenient.

[0061] In some embodiments, referring to FIG. 9, at least two first attractive members 21 are arranged. At least one of the first attractive members 21 is configured to generate an attractive force with the third attractive member 41, and at least one of the first attractive members 21 is configured to generate an attractive force with the second attractive member 31.

[0062] The above arrangement helps achieve a more stable connection between the power supply assembly 20 and the functional assembly 10.

[0063] One or more second attractive members 31 may be arranged. One or more third attractive members 41 may be arranged.

[0064] In some embodiments, the first attractive member 21, the second attractive member 31, and the third attractive member 41 are all magnets. Polarities of the second attractive member 31 and the third attractive member 41 are opposite to a polarity of the first attractive member 21, to implement mutual attraction between the first attractive member 21 and the second attractive member 31 and mutual attraction between the first attractive member 21 and the third attractive member 41 through attraction between opposite polarities.

[0065] In some embodiments, referring to FIG. 18 and FIG. 19, the aerosol generating device further includes a guide slot 10b and a guide portion 22. The power supply assembly 20 is provided with one of the guide slot 10b and the guide portion 22, and the functional assembly 10 is provided with the other of the guide slot and the guide portion. An extension direction of the guide slot 10b is the same as an extension direction of the guide portion 22 and intersects the second direction. The two sides of the guide slot 10b in the second direction are closed, and at least one end of the guide slot 10b in the extension direction of the guide slot is open, for the guide portion 22 to enter and exit the guide slot 10b in the extension direction of the guide slot 10b.

[0066] The guide portion 22 enters the guide slot 10b from an open position of the guide slot 10b and moves in the extension direction of the guide slot 10b. Constrained by the two side inner walls of the guide slot 10b in the second direction, the guide portion 22 is not easily detached from the guide slot 10b in the second direction, thereby preventing relative movement between the functional assembly 10 and the power supply assembly 20 in the second direction.

[0067] Through the engagement between the guide portion 22 and the guide slot 10b, a detachable connection is achieved between the functional assembly 10 and the power supply assembly 20, which has a simple structure and facilitates operation.

[0068] One or more guide portions 22 and guide slots 10b may be arranged, which is not limited to a specific quantity.

[0069] In some embodiments, only the atomizer 30 is provided with the guide slot 10b. In some embodiments, only the additional e-liquid tank 40 is provided with the guide slot 10b. In some other embodiments, referring to FIG. 18, the guide slot 10b includes a first sub-slot 10c and a second sub-slot 10d, the first sub-slot 10c is located at the atomizer 30, the second sub-slot 10d is located at the additional e-liquid tank 40, and in terms of a projection perpendicular to the extension direction of the guide slot 10b, a projection of the first sub-slot 10c coincides with a projection of the second sub-slot 10d.

[0070] It may be understood that the guide portion 22 and the guide slot 10b both extend linearly.

[0071] In some embodiments, referring to FIG. 18, the functional assembly 10 is provided with a limiting portion 12, and the limiting portion 12 is arranged on the end of the guide slot 10b facing away from an open position of the guide slot in the extension direction of the guide slot. In terms of a projection perpendicular to the extension direction of the guide slot 10b, at least part of a projection of the limiting portion 12 is located in a projection range of the guide slot 10b. In a state in which the atomizer 30 is electrically connected to the power supply assembly 20, the limiting portion 12 abuts against the guide portion 22, so that the user determines that relative positions of the functional assembly 10 and the power supply assembly 20 satisfy a requirement during mounting.

[0072] It may be understood that, during use of the aerosol generating device, a probability that the electrical connection between the atomizer 30 and the power supply assembly 20 fails as a result of relative movement being generated between the guide portion 22 and the guide slot 10b needs to be reduced.

[0073] In some embodiments, referring to FIG. 16, FIG. 18, and FIG. 19, the aerosol generating device further includes an elastic portion 23 and a stop portion 11, the power supply assembly 20 is provided with one of the elastic portion 23 and the stop portion 11, and the functional assembly 10 is provided with the other of the elastic portion and the stop portion. The elastic portion 23 can elastically stretch perpendicularly to the extension direction of the guide slot 10b. In a state in which the guide portion 22 is embedded in the guide slot 10b, in terms of a projection perpendicular to the extension direction of the guide slot 10b, at least part of a projection of the elastic portion 23 coincides with a projection of the stop portion 11. In a state in which the power supply assembly 20 is electrically connected to the atomizer 30, the elastic portion 23 is located on the side of the stop portion 11 facing away from the open position of the guide slot 10b in the extension direction of the guide slot 10b, and the elastic portion and the stop portion abut in the extension direction of the guide slot 10b.

[0074] After being embedded into the guide slot 10b, the guide portion 22 moves in the extension direction of the guide slot 10b until the elastic portion 23 abuts against the stop portion 11 in the extension direction of the guide slot 10b. The functional assembly 10 and the power supply assembly 20 are further pushed to move relative to each other, so that the stop portion 11 presses the elastic portion 23 into deformation, until the elastic portion 23 deforms to a state in which the elastic portion no longer abuts against the stop portion 11 in the extension direction of the guide slot 10b, so that the stop portion 11 moves from the side of the elastic portion 23 close to the open position of the guide slot 10b to the side of the elastic portion away from the open position of the guide slot 10b. In this state, the power supply assembly 20 is electrically connected to the atomizer 30, and the elastic portion 23 abuts against the stop portion 11 in the extension direction of the guide slot 10b. The user then applies an opposite action force, which causes the guide portion 22 to move toward the open position of the guide slot 10b, so that the stop portion 11 presses the elastic portion 23 into deformation, until the elastic portion 23 deforms to a state in which the elastic portion no longer abuts with the stop portion 11 in the extension direction of the guide slot 10b, so that the stop portion 11 moves from the side of the elastic portion 23 away from the open position of the guide slot 10b to the side of the elastic portion close to the open position of the guide slot 10b. In this way, the guide portion 22 can further move to completely exit the guide slot 10b.

[0075] Through the collaboration between the elastic portion 23 and the stop portion 11, relative positions of the functional assembly 10 and the power supply assembly 20 in the extension direction of the guide slot 10b are maintained to be stable.

[0076] A specific manner of implementing the elastic deformation of the elastic portion 23 is not limited. For example, referring to FIG. 16, a cavity is provided in the elastic portion 23, to weaken structural strength of the elastic portion 23, so that the elastic portion 23 deforms under the pressing of the stop portion 11.

[0077] It may be understood that, in some embodiments provided with the limiting portion 12, in a state in which the power supply assembly 20 is electrically connected to the atomizer 30, the elastic portion 23 abuts against the stop portion 11, and the guide portion 22 abuts against the inner wall of the guide slot 10b in the extension direction of the guide slot, so that relative positions of the functional assembly 10 and the power supply assembly 20 are fixed.

[0078] In some embodiments, referring to FIG. 16, FIG. 18, and FIG. 19, the two sides of the elastic portion 23 in the extension direction of the guide slot 10b are both inclined surfaces, and the two sides of the stop portion 11 in the extension direction of the guide slot 10b are both inclined surfaces, so that the stop portion 11 presses the elastic portion 23 into deformation.

[0079] In some embodiments, referring to FIG. 18, at least part of the inner wall of the accommodating cavity 20a defines the guide slot 10b, so that the structure is more compact.

[0080] In some embodiments, referring to FIG. 18, at least part of the inner wall of the accommodating cavity 20a forms the limiting portion 12, so that the structure is more compact.

[0081] A specific manner of implementing the electrical connection between the atomizer 30 and the power supply assembly 20 is not limited.

[0082] In some embodiments, referring to FIG. 6 to FIG. 8, FIG. 16 to FIG. 18, FIG. 22, and FIG. 23, the aerosol generating device includes a first pin 50 and an electric wire 34, the atomizer 30 is provided with a second mounting hole 30d, at least part of the first pin 50 is inserted in the second mounting hole 30d, the electric wire 34 is electrically connected to the atomizer 30, a part of the electric wire 34 is sandwiched between the inner wall of the second mounting hole 30d and the first pin 50, to electrically connect the electric wire 34 to the first pin 50, the end of the first pin 50 in the second direction is located on the side of the atomizer 30 in the second direction, the surface on the side of the power supply assembly 20 in the second direction is provided with a power supply contact, and the first pin 50 contacts the power supply contact, to electrically connect the first pin to the power supply contact.

[0083] At least part of the first pin 50 is made of a conductive material, to achieve conductivity. A specific type of the conductive material that is used is not limited, for example, copper.

[0084] Because at least part of the electric wire 34 is sandwiched between the inner wall of the second mounting hole 30d and the first pin 50, not only an electrical conduction is achieved between the electric wire 34 and the first pin 50, but also limitation is provided for the first pin 50 and the electric wire through a friction among the electric wire 34, the inner wall of the second mounting hole 30d, and the first pin 50, to maintain a stable electrical connection state between the electric wire and the first pin.

[0085] A part of the electric wire 34 may be inserted into the second mounting hole 30d in advance, and then the first pin 50 is pressed into the second mounting hole 30d, so that the electric wire 34 is sandwiched between the inner wall of the second mounting hole 30d and the first pin 50. Therefore, the fixing between the electric wire 34 and the first pin 50 does not need to be implemented through soldering or adhesion, thereby simplifying fitting steps of the atomizer 30.

[0086] In some embodiments, referring to FIG. 6 to FIG. 8, FIG. 16 to FIG. 18, FIG. 22, and FIG. 23, the atomizer 30 includes an atomizer housing 32 and an atomization assembly 33, the main storage cavity 30a is located at the atomization assembly 33, the atomization assembly 33 and the atomizer housing 32 define a first cavity 30b, and the electric wire 34 is at least partially located in the first cavity 30b.

[0087] In this way, a particular protection function can be provided for the electric wire 34.

[0088] In some embodiments, referring to FIG. 7 and FIG. 17, the end surface on the end of the first pin 50 in the second direction is flush with the end surface the end of the atomizer housing 32 in a second direction, to reduce a probability that the first pin 50 is damaged by collision during mounting and dismounting of the functional assembly 10. A specific position of the second mounting hole 30d is not limited.

[0089] In some embodiments, the atomizer housing 32 is provided with a second mounting hole 30d, and the second mounting hole 30d is in communication with the first cavity 30b and outside of the atomizer.

[0090] In some other embodiments, referring to FIG. 6 to FIG. 8, FIG. 16 to FIG. 18, FIG. 22, and FIG. 23, the atomizer housing 32 is provided with a first mounting hole 30c, the first mounting hole 30c is in communication with the first cavity 30b and outside of the atomizer 30, at least one of the atomization assembly 33 and the atomizer housing 32 is provided with a second mounting hole 30d, the second mounting hole 30d is located in the first cavity 30b, the first pin 50 is inserted in the first mounting hole 30c and the second mounting hole 30d, and the electric wire 34 is electrically connected to the atomization assembly 33.

[0091] The atomization assembly 33 is configured to convert the aerosol generating substrate into aerosols.

[0092] The electric wire 34 has conductivity, and has a flexible structure so as to flexibly bend the electric wire 34 based on a relative position relationship between an electrical connection location between the atomization assembly 33 and the electric wire and the second mounting hole 30d, thereby improving mounting adaptability.

[0093] In some embodiments, referring to FIG. 7, the first mounting hole 30c is located on the side of the atomizer housing 32 in the second direction, to reduce a distance with the power supply assembly 20, thereby facilitating the electrical connection of the first pin 50 to the power supply assembly 20.

[0094] In some embodiments, referring to FIG. 6, the atomization assembly 33 includes an atomization core 331, and the electric wire 34 is electrically connected to the atomization core 331, so that the power supply assembly 20, the electric wire 34, and the atomization core 331 form an electric path, to help the power supply assembly 20 provide electric energy to the atomization core 331.

[0095] In some embodiments, referring to FIG. 7 and FIG. 17, an extension direction of the first mounting hole 30c is the same as an extension direction of the second mounting hole 30d, the end of the second mounting hole 30d is open toward the first mounting hole 30c, and at least part of the first pin 50 may run through the first mounting hole 30c.

[0096] The extension direction of the first mounting hole 30c is a depth direction of the first mounting hole 30c. The extension direction of the second mounting hole 30d is a depth direction of the second mounting hole 30d.

[0097] In other words, in terms of a projection perpendicular to the extension direction of the first mounting hole 30c, at least part of a projection of the first pin 50 can completely coincide with a projection of the first mounting hole 30c or is smaller than the projection of the first mounting hole 30c. In this way, after the atomizer 30 is completely fitted, at least part of the first pin 50 may be inserted into the second mounting hole 30d from outside of the atomizer housing 32, and the inner wall of the first mounting hole 30c can provide guidance and limitation for insertion of the first pin 50, so that the first pin 50 can be accurately inserted into the second mounting hole 30d.

[0098] In some embodiments in which the atomization cavity 331a is in communication with the first cavity 30b, the atomizer housing 32 is provided with an air inlet hole 32a, and the air inlet hole 32a in communication with the first cavity 30b and outside of the aerosol generating device. It may be understood that, the functional assembly 10 and the power supply assembly 20 may be detachably connected, so that a joint exists between the functional assembly and the power supply assembly.

[0099] In some embodiments, referring to FIG. 7 and FIG. 17, the atomization assembly 33 is provided with an atomization cavity 331a, the atomization cavity 331a is in communication with the first cavity 30b, and the first pin 50 is hermetically attached to the inner wall of the first mounting hole 30c.

[0100] The first pin 50 is hermetically attached to the inner wall of the first mounting hole 30c, so that external air cannot easily enter the first cavity 30b through the first mounting hole 30c during inhalation of aerosols by the user, which helps form negative air pressure in the first cavity 30b, thereby helping air outside the aerosol generating device enter the first cavity 30b and then enter the atomization cavity 331a.

[0101] It may be understood that, liquids are formed after residual aerosols in the atomization cavity 331a condense, which flow into the first cavity 30b.

[0102] In some embodiments, interference fit is adopted between the second mounting hole 30d and the first pin 50, to fix a part of the electric wire 34 between the inner wall of the second mounting hole 30d and the first pin 50.

[0103] In some embodiments, in terms of a projection perpendicular to an extension direction of the atomization cavity 331a, a projection of the first pin 50 and a projection of the second mounting hole 30d are both located outside a projection of a communication position between the atomization cavity 331a and the first cavity 30b, to reduce a probability that condensates directly contact the first pin 50 and the connection position between the first pin 50 and the electric wire 34.

[0104] In some embodiments, referring to FIG. 3, FIG. 6, FIG. 16, and FIG. 22, the atomization assembly 33 is provided with an atomization cavity 331a, the atomization cavity 331a is in communication with the first cavity 30b, the atomizer 30 further includes a liquid absorbing member 35, and the liquid absorbing member 35 is located in the first cavity 30b.

[0105] Through the liquid absorbing member 35, a partial space in the first cavity 30b may be occupied, so that negative pressure can be formed in the first cavity 30b more quickly; and the liquid absorbing member 35 can absorb the condensates, thereby reducing a probability of corrosion of the electric wire 34 by the condensates and reducing a leakage risk of the condensates.

[0106] The liquid absorbing member 35 is provided therein with pores to absorb the aerosol generating substrate.

[0107] It may be understood that, the pores of the liquid absorbing member 35 may be pores that can be macroscopically identified by naked eyes, or may be pores that cannot be microscopically identified by naked eyes, as long as the pores can absorb the aerosol generating substrate through a capillarity action and allow airflows to pass through.

[0108] A specific form of the liquid absorbing member 35 is not limited, and is, for example, a fiber structure formed by braiding or twisting of chemical fiber such as batt, sponge, polyester, or chinlon.

[0109] It may be understood that, a material of the aerosol generating substrate relative to the liquid absorbing member 35 is a wetting liquid, so that the aerosol generating substrate can be attached to or absorbed by the liquid absorbing member 35.

[0110] In some embodiments, referring to FIG. 7, FIG. 17, and FIG. 23, the atomizer 30 includes an elastic fixing base 36, the elastic fixing base 36 is made of an elastic material, and the second mounting hole 30d runs through the elastic fixing base 36. Through elastic deformation of the elastic fixing base 36, an elastic action is generated on the inner wall of the second mounting hole 30d, which helps enhance a pressing action between the inner wall of the second mounting hole 30d and the first pin 50 on the electric wire 34, thereby improving stability of the electrical connection between the first pin 50 and the electric wire 34.

[0111] In some embodiments, the elastic fixing base 36 is arranged on the atomization assembly 33.

[0112] It may be understood that, the main storage cavity 30a and the atomization cavity 331a are isolated from each other.

[0113] In some embodiments in which the first mounting hole 30c is located on the side of the atomizer housing 32 in the second direction, referring to FIG. 3, FIG. 7, FIG. 16, and FIG. 17, the power supply assembly 20 includes a power supply housing 24, a power supply member 25, and a second pin 26, the power supply housing 24 is provided with a second cavity 24b and a fourth mounting hole 24a, the fourth mounting hole 24a is in communication with outside of the second cavity 24b and the power supply assembly 20, the fourth mounting hole 24a extends in the second direction, the power supply member 25 is located in the second cavity 24b, at least part of the second pin 26 is located in the second cavity 24b and is electrically connected to the power supply member 25, the second pin 26 is inserted in the fourth mounting hole 24a, the second pin 26 can stretch and contract in the second direction, and the second pin 26 can abut against the first pin 50 in the second direction.

[0114] Through contact between the first pin 50 and the second pin 26, an electrical connection is implemented, thereby implementing the electrical connection between the power supply assembly 20 and the atomizer 30. Through stretching and contraction of the second pin 26, the second pin 26 can be maintained in contact with the first pin 50, thereby helping maintain a stable electrical connection.

[0115] It may be understood that, a part of the second pin 26 forms a power supply contact.

[0116] Types of electronic components included in the power supply assembly 20 are not limited. For example, the power supply assembly includes a power supply member 25, a printed circuit board (PCB), and an air pressure sensor 28.

[0117] A specific type of the power supply member 25 is not limited. For example, the power supply member is a lithium battery.

[0118] In some embodiments, referring to FIG. 4, FIG. 5, FIG. 8, FIG. 16 to FIG. 18, FIG. 22, and FIG. 23, the functional assembly 10 is provided with an airflow channel and a first air pressure hole 10e, the outlet and the inlet of the airflow channel are both in communication with the outside of the aerosol generating device, the first air pressure hole 10e is in communication with the airflow channel and outside of the functional assembly 10, the power supply assembly 20 includes a power supply housing 24, an elastic mounting base 27, and an air pressure sensor 28, the power supply housing 24 is provided therein with a second cavity 24b and a third mounting hole, the third mounting hole is in communication with the second cavity 24b and outside of the power supply assembly 20, the elastic mounting base 27 is inserted in the third mounting hole, the elastic mounting base 27 is provided with a second air pressure hole 27a, a sensing area of the air pressure sensor 28 is located at the second air pressure hole 27a, and in a state in which the power supply assembly 20 is electrically connected to the atomizer 30, the elastic mounting base 27 is hermetically attached to the functional assembly 10, and the second air pressure hole 27a is in communication with the first air pressure hole 10e.

[0119] An airflow outside the aerosol generating device enters the airflow channel through the inlet of the airflow channel, and is mixed with an aerosol in the airflow channel, and then is discharged through the outlet of the airflow channel and enters the oral cavity of the user.

[0120] It may be understood that during inhalation by the user, air pressure in the airflow channel decreases, so that air pressure in the first air pressure hole 10e decreases, and air pressure in the second air pressure hole 27a decreases, so that the air pressure sensor 28 can sense a change of the air pressure, and then control the power supply member 25 to supply power to the atomizer 30.

[0121] The elastic mounting base 27 can elastically deform. The elastic mounting base 27 abuts against the functional assembly 10, so that the elastic mounting base 27 deforms, which reduces a probability that external air enters the second air pressure hole 27a through a joint between the elastic mounting base 27 and the functional assembly 10, and helps the air pressure sensor 28 more accurately sense negative air pressure generated in the second air pressure hole 27a from the inhalation by the user, thereby helping increase a response speed of the aerosol generating device.

[0122] A specific material of the elastic mounting base 27 is not limited, which is, for example, silicon or rubber.

[0123] In some embodiments, the air inlet hole 32a, the first cavity 30b, the atomization cavity 331a, and the air outlet channel 10a each form a part of the airflow channel.

[0124] In some embodiments, referring to FIG. 5 and FIG. 23, the elastic mounting base 27 includes an elastic skirt 271, the elastic skirt 271 surrounds an opening on the end of the second air pressure hole 27a, the elastic skirt 271 is inclined in the second direction and extends away from the opening of the second air pressure hole 27a, and the elastic skirt 271 is configured to be hermetically attached to the functional assembly 10. In this way, the elastic skirt 271 can deform more easily under an action force in the second direction, which helps improve sealing performance between the elastic mounting base 27 and the functional assembly 10.

[0125] In some embodiments provided with the atomizer housing 32, the atomization assembly 33, and the liquid absorbing member 35, referring to FIG. 16 and FIG. 17, the atomization assembly 33 and the atomizer housing 32 define the first cavity 30b, the first air pressure hole 10e is located at the atomizer housing 32 and is in communication with the first cavity 30b, the liquid absorbing member 35 is located in the first cavity 30b, and the first cavity 30b forms a part of the airflow channel.

[0126] In this way, the liquid absorbing member 35 in the first cavity 30b can absorb the condensates, which reduces a probability that the condensates enter the second air pressure hole 27a and contact the air pressure sensor 28, thereby helping increase a service life of the air pressure sensor 28.

[0127] In some embodiments, referring to FIG. 10, FIG. 11, and FIG. 22, the additional e-liquid tank 40 includes an e-liquid tank housing 42, a mounting plug 43, and an elastic sealing member 44, the e-liquid tank housing 42 is provided therein with a storage space, the side of the storage space is open, the mounting plug 43 covers an open position of the storage space, the mounting plug 43 is provided with a plugging channel, the plugging channel is in communication with the additional storage cavity 40a and outside of the additional e-liquid tank 40, the elastic sealing member 44 includes an annular portion 441 sand a blocking portion 442, the annular portion 441 is sandwiched between the mounting plug 43 and the e-liquid tank housing 42, the e-liquid tank housing 42, the mounting plug 43, and the elastic sealing member 44 jointly define the additional storage cavity 40a, the blocking portion 442 is connected to the annular portion 441, and the blocking portion 442 blocks a communication port between the plugging channel and the additional storage cavity 40a. A part of the atomizer 30 may be inserted into the plugging channel, to push the blocking portion 442 to detach to open the plugging channel, so that the main storage cavity 30a is in communication with the additional storage cavity 40a.

[0128] Therefore, a same part is used for both sealing the e-liquid tank housing 42 and the mounting plug 43 and blocking the plugging channel, which helps reduce a quantity of parts in the additional e-liquid tank 40, and helps reduce production and assembly costs.

[0129] In some embodiments, referring to FIG. 3 and FIG. 13, the external surface of the atomization assembly 33 is provided with an insertion column 332, the insertion column 332 extends in the first direction, the insertion column 332 is provided with a liquid inlet channel 332a running through the insertion column, the liquid inlet channel 332a is in communication with the main storage cavity 30a and the outside of the atomization assembly 33, and the insertion column 332 is configured to be inserted into the plugging channel to push the blocking portion 442 to open the plugging channel.

[0131] In some embodiments in which the functional assembly 10 is provided with the air outlet channel 10a, referring to FIG. 22, the outlet of the air outlet channel 10a is located on the side of the functional assembly 10 away from the power supply assembly 20 in the second direction.

[0134] The air inlet channel is used for an external airflow to enter the functional assembly 10, so as to mix with the aerosols in the atomization cavity 331a. In this way, the condensates in the atomization cavity can enter the air inlet channel.

The above arrangement helps the elastic mounting base 27 to be more tightly attached to the first surface 10f, thereby improving a sealing effect for communication between the first air pressure hole 10e and the second air pressure hole 27a.

[0140] In some embodiments, the additional e-liquid tank 40 and the atomizer 30 may be detachably connected, to replace the additional e-liquid tank 40 with a new one after the aerosol generating substrate in the additional storage cavity 40a is exhausted.

[0141] It may be understood that in a state in which the additional e-liquid tank 40 and the atomizer 30 are disassembled, the additional storage cavity 40a is no longer in communication with the main storage cavity 30a.

[0142] A manner of implementing the detachable connection between the atomizer 30 and the additional e-liquid tank 40 is not limited.

[0145] During use of the aerosol generating device, a part of the external surface of any one of the atomizer 30, the additional e-liquid tank 40, and the power supply assembly 20 can be directly observed by the user. In this way, when the aerosol generating substrate in the additional storage cavity 40a is exhausted, or at least one of the atomizer 30, the additional e-liquid tank 40, and the power supply assembly 20 is damaged, a force is directly applied to one of the atomizer 30, the additional e-liquid tank 40, and the power supply assembly 20 that needs to be dismounted, so as to separate one of the atomizer, the additional e-liquid tank, and the power supply assembly from the other two, thereby facilitating a subsequent independent operation.

[0031] Embodiments of this application provide an aerosol generating device, to generate aerosols for a user to inhale. Referring to FIG. 1 to FIG. 3, FIG. 14 to FIG. 16, FIG. 20 to FIG. 22, and FIG. 24 to FIG. 26, the aerosol generating device includes a functional assembly 10 and a power supply assembly 20.

[0032] The functional assembly 10 includes an additional e-liquid tank 40 and an atomizer 30, the additional e-liquid tank 40 is provided with an additional storage cavity 40a, the atomizer 30 is located on the side of the additional e-liquid tank 40 in a first direction, the atomizer 30 is provided with a main storage cavity 30a, and the main storage cavity 30a may be in communication with the additional storage cavity 40a.

[0033] The power supply assembly 20 is located on the side of the functional assembly 10 in a second direction, the first direction intersects the second direction, and the power supply assembly 20 is electrically connected to the atomizer 30.

[0034] The functional assembly 10 and the power supply assembly 20 are detachably connected.

[0035] The functional assembly 10 is a part of the aerosol generating device that may be configured to implement a function of converting an aerosol generating substrate into aerosols.

[0036] The additional storage cavity 40a is configured to store an aerosol generating substrate. The main storage cavity 30a is configured to store an aerosol generating substrate.

[0037] The atomizer 30 includes an atomization core 331, and the atomization core 331 is provided therein with an atomization cavity 331a. The main storage cavity 30a is isolated from the atomization cavity 331a. The atomization core 331 continuously converts the aerosol generating substrate in the main storage cavity 30a into aerosols. As the aerosols in the main storage cavity 30a are continuously consumed, the aerosol generating substrate in the additional storage cavity 40a can be continuously replenished to the main storage cavity 30a, thereby reducing problems such as dry heating of the atomization core 331 and increasing a service life of the aerosol generating device.

[0038] The power supply assembly 20 is configured to provide electric energy to the atomizer 30.

[0039] The atomizer 30 and the additional e-liquid tank 40 are arranged in the first direction, so that an aerosol generating substrate between the two mainly flows in the first direction.

[0040] It may be understood that the power supply assembly 20 includes various types of electronic components configured to implement normal operation of the atomizer 30. However, the aerosol generating substrate and condensates formed after condensation of the aerosols lead to problems such as a short circuit in the electronic components, and corrode the electronic components.

[0041] The power supply assembly 20 is located on the side of the functional assembly 10 in the second direction. That is, the atomizer 30, the additional e-liquid tank 40, and the power supply assembly 20 are not all arranged in the first direction. The above arrangement helps the power supply assembly 20 be away from the aerosol generating substrate flowing between the atomizer 30 and the additional e-liquid tank 40.

[0042] The functional assembly 10 and the power supply assembly 20 are detachably connected to each other. In this way, one of the two may be independently dismounted for service and replacement when damaged.

[0043] According to the aerosol generating device provided in the embodiments of this application, an arrangement direction of the functional assembly 10 and the power supply assembly 20 is different from an arrangement direction of the atomizer 30 and the additional e-liquid tank 40, which helps reduce a risk that liquids such as an aerosol generating substrate and condensates in the atomizer 30 and the additional e-liquid tank infiltrate the power supply assembly 20 and damage the electronic components in the power supply assembly 20, thereby increasing a service life of the power supply assembly 20.

[0044] In some embodiments, the first direction is perpendicular to the second direction, to help reduce an outer contour size of the aerosol generating device.

[0045] It may be understood that in a state in which the power supply assembly 20 and the functional assembly 10 are disassembled, the power supply assembly 20 is no longer electrically connected to the atomizer 30.

[0046] In some embodiments, the atomizer 30 is provided with an atomization cavity 331a, the functional assembly 10 is provided with an air outlet channel 10a, and outside of the aerosol generating device is in communication with the atomization cavity 331a through the air outlet channel 10a.

[0047] During inhalation of the aerosols by a user, the outlet of the air outlet channel 10a is configured to be in communication with an oral cavity of the user, so that the aerosols in the atomization cavity 331a enter the oral cavity of the user through the air outlet channel 10a.

[0048] In some embodiments, referring to FIG. 3 and FIG. 16, the additional e-liquid tank 40 is provided with an air outlet channel 10a, the air outlet channel 10a is in communication with the outside of the aerosol generating device, and the atomizer 30 is located on the side of the additional e-liquid tank 40 away from the outlet of the air outlet channel 10a in the first direction.

[0049] Providing the air outlet channel 10a through the additional e-liquid tank 40 helps lengthen an air flow path for aerosols discharged from the atomizer 30 to flow out of the aerosol generating device, which helps reduce a temperature of the aerosols to a suitable temperature range, thereby reducing problems such as mouth burning during use by the user. The additional e-liquid tank 40 may be replaced, to reduce hygiene risks to the user caused by hygiene issues such as bacterial growth in the air outlet channel 10a.

[0050] In some embodiments, referring to FIG. 26, the atomizer 30 is provided with an air outlet channel 10a, the air outlet channel 10a is in communication with the outside of the aerosol generating device, and the additional e-liquid tank 40 is located on the side of the atomizer 30 away from the outlet of the air outlet channel 10a in the first direction.

[0051] That is, the air outlet channel 10a does not run through the additional e-liquid tank 40.

[0052] The above arrangement helps increase a volume of the additional storage cavity 40a in a limited space, shorten a flow path of the aerosols, reduce a loss of the aerosols, reduce a probability that the aerosol generating substrate in the additional storage cavity 40a can always flow into the main storage cavity 30a, reduce a probability of supersaturation of the aerosol generating substrate in the main storage cavity 30a, and improve a taste of the aerosols.

[0053] In some embodiments, referring to FIG. 22, the atomizer 30 is provided with an air outlet channel 10a, the air outlet channel 10a is in communication with the outside of the aerosol generating device, and an extension direction of the air outlet channel 10a intersects the first direction. The above arrangement helps increase a volume of the additional storage cavity 40a in a limited space.

[0054] In some embodiments, the first direction substantially a vertical direction during use of the aerosol generating device by the user.

[0055] In some embodiments, referring to FIG. 9 and FIG. 18, one of the functional assembly 10 and the power supply assembly 20 is provided with an accommodating cavity 20a, and the accommodating cavity 20a is open in the second direction, for a part of the other of the functional assembly 10 and the power supply assembly 20 to enter the accommodating cavity 20a.

[0056] Because the inner wall of the accommodating cavity 20a can shield a detachable connection position and an electrical connection position between the functional assembly 10 and the power supply assembly 20, a risk of a connection failure and a risk of an electrical connection failure are reduced. A specific manner of implementing the detachable connection between the functional assembly 10 and the power supply assembly 20 is not limited.

[0057] In some embodiments, referring to FIG. 3, FIG. 8, and FIG. 9, the power supply assembly 20 includes a first attractive member 21, the atomizer 30 includes a second attractive member 31, and at least an attractive force in the second direction can be generated between the first attractive member 21 and the second attractive member 31.

[0058] Through the attractive force between the first attractive member 21 and the second attractive member 31, the power supply assembly 20 and the atomizer 30 can be attached to each other, thereby helping maintain the electrical connection state between the power supply assembly and the atomizer. The user applies an action force opposite the attractive force in the second direction to the power supply assembly 20 and the atomizer 30, which overcomes the attractive force, to separate the atomizer 30 from the power supply assembly 20, thereby achieving disassembly of the two. The operation is simple and convenient.

[0059] In some embodiments, referring to FIG. 3, FIG. 8, and FIG. 9, the additional e-liquid tank 40 includes a third attractive member 41, and at least an attractive force in the second direction can be generated between the first attractive member 21 and the third attractive member 41.

[0060] Though the attractive force between the first attractive member 21 and the third attractive member 41, the power supply assembly 20 can be attached to the functional assembly 10, thereby helping maintain the electrical connection state between the power supply assembly 20 and the atomizer 30. The user applies an action force opposite the attractive force in the second direction to the power supply assembly 20 and the atomizer 30, which overcomes the attractive force, to separate the atomizer 30 from the power supply assembly 20, thereby achieving disassembly of the two. The operation is simple and convenient.

[0061] In some embodiments, referring to FIG. 9, at least two first attractive members 21 are arranged. At least one of the first attractive members 21 is configured to generate an attractive force with the third attractive member 41, and at least one of the first attractive members 21 is configured to generate an attractive force with the second attractive member 31.

[0062] The above arrangement helps achieve a more stable connection between the power supply assembly 20 and the functional assembly 10.

[0063] One or more second attractive members 31 may be arranged. One or more third attractive members 41 may be arranged.

[0064] In some embodiments, the first attractive member 21, the second attractive member 31, and the third attractive member 41 are all magnets. Polarities of the second attractive member 31 and the third attractive member 41 are opposite to a polarity of the first attractive member 21, to implement mutual attraction between the first attractive member 21 and the second attractive member 31 and mutual attraction between the first attractive member 21 and the third attractive member 41 through attraction between opposite polarities.

[0065] In some embodiments, referring to FIG. 18 and FIG. 19, the aerosol generating device further includes a guide slot 10b and a guide portion 22. The power supply assembly 20 is provided with one of the guide slot 10b and the guide portion 22, and the functional assembly 10 is provided with the other of the guide slot and the guide portion. An extension direction of the guide slot 10b is the same as an extension direction of the guide portion 22 and intersects the second direction. The two sides of the guide slot 10b in the second direction are closed, and at least one end of the guide slot 10b in the extension direction of the guide slot is open, for the guide portion 22 to enter and exit the guide slot 10b in the extension direction of the guide slot 10b.

[0066] The guide portion 22 enters the guide slot 10b from an open position of the guide slot 10b and moves in the extension direction of the guide slot 10b. Constrained by the two side inner walls of the guide slot 10b in the second direction, the guide portion 22 is not easily detached from the guide slot 10b in the second direction, thereby preventing relative movement between the functional assembly 10 and the power supply assembly 20 in the second direction.

[0067] Through the engagement between the guide portion 22 and the guide slot 10b, a detachable connection is achieved between the functional assembly 10 and the power supply assembly 20, which has a simple structure and facilitates operation.

[0068] One or more guide portions 22 and guide slots 10b may be arranged, which is not limited to a specific quantity.

[0069] In some embodiments, only the atomizer 30 is provided with the guide slot 10b. In some embodiments, only the additional e-liquid tank 40 is provided with the guide slot 10b. In some other embodiments, referring to FIG. 18, the guide slot 10b includes a first sub-slot 10c and a second sub-slot 10d, the first sub-slot 10c is located at the atomizer 30, the second sub-slot 10d is located at the additional e-liquid tank 40, and in terms of a projection perpendicular to the extension direction of the guide slot 10b, a projection of the first sub-slot 10c coincides with a projection of the second sub-slot 10d.

[0070] It may be understood that the guide portion 22 and the guide slot 10b both extend linearly.

[0071] In some embodiments, referring to FIG. 18, the functional assembly 10 is provided with a limiting portion 12, and the limiting portion 12 is arranged on the end of the guide slot 10b facing away from an open position of the guide slot in the extension direction of the guide slot. In terms of a projection perpendicular to the extension direction of the guide slot 10b, at least part of a projection of the limiting portion 12 is located in a projection range of the guide slot 10b. In a state in which the atomizer 30 is electrically connected to the power supply assembly 20, the limiting portion 12 abuts against the guide portion 22, so that the user determines that relative positions of the functional assembly 10 and the power supply assembly 20 satisfy a requirement during mounting.

[0072] It may be understood that, during use of the aerosol generating device, a probability that the electrical connection between the atomizer 30 and the power supply assembly 20 fails as a result of relative movement being generated between the guide portion 22 and the guide slot 10b needs to be reduced.

[0073] In some embodiments, referring to FIG. 16, FIG. 18, and FIG. 19, the aerosol generating device further includes an elastic portion 23 and a stop portion 11, the power supply assembly 20 is provided with one of the elastic portion 23 and the stop portion 11, and the functional assembly 10 is provided with the other of the elastic portion and the stop portion. The elastic portion 23 can elastically stretch perpendicularly to the extension direction of the guide slot 10b. In a state in which the guide portion 22 is embedded in the guide slot 10b, in terms of a projection perpendicular to the extension direction of the guide slot 10b, at least part of a projection of the elastic portion 23 coincides with a projection of the stop portion 11. In a state in which the power supply assembly 20 is electrically connected to the atomizer 30, the elastic portion 23 is located on the side of the stop portion 11 facing away from the open position of the guide slot 10b in the extension direction of the guide slot 10b, and the elastic portion and the stop portion abut in the extension direction of the guide slot 10b.

[0074] After being embedded into the guide slot 10b, the guide portion 22 moves in the extension direction of the guide slot 10b until the elastic portion 23 abuts against the stop portion 11 in the extension direction of the guide slot 10b. The functional assembly 10 and the power supply assembly 20 are further pushed to move relative to each other, so that the stop portion 11 presses the elastic portion 23 into deformation, until the elastic portion 23 deforms to a state in which the elastic portion no longer abuts against the stop portion 11 in the extension direction of the guide slot 10b, so that the stop portion 11 moves from the side of the elastic portion 23 close to the open position of the guide slot 10b to the side of the elastic portion away from the open position of the guide slot 10b. In this state, the power supply assembly 20 is electrically connected to the atomizer 30, and the elastic portion 23 abuts against the stop portion 11 in the extension direction of the guide slot 10b. The user then applies an opposite action force, which causes the guide portion 22 to move toward the open position of the guide slot 10b, so that the stop portion 11 presses the elastic portion 23 into deformation, until the elastic portion 23 deforms to a state in which the elastic portion no longer abuts with the stop portion 11 in the extension direction of the guide slot 10b, so that the stop portion 11 moves from the side of the elastic portion 23 away from the open position of the guide slot 10b to the side of the elastic portion close to the open position of the guide slot 10b. In this way, the guide portion 22 can further move to completely exit the guide slot 10b.

[0075] Through the collaboration between the elastic portion 23 and the stop portion 11, relative positions of the functional assembly 10 and the power supply assembly 20 in the extension direction of the guide slot 10b are maintained to be stable.

[0076] A specific manner of implementing the elastic deformation of the elastic portion 23 is not limited. For example, referring to FIG. 16, a cavity is provided in the elastic portion 23, to weaken structural strength of the elastic portion 23, so that the elastic portion 23 deforms under the pressing of the stop portion 11.

[0077] It may be understood that, in some embodiments provided with the limiting portion 12, in a state in which the power supply assembly 20 is electrically connected to the atomizer 30, the elastic portion 23 abuts against the stop portion 11, and the guide portion 22 abuts against the inner wall of the guide slot 10b in the extension direction of the guide slot, so that relative positions of the functional assembly 10 and the power supply assembly 20 are fixed.

[0078] In some embodiments, referring to FIG. 16, FIG. 18, and FIG. 19, the two sides of the elastic portion 23 in the extension direction of the guide slot 10b are both inclined surfaces, and the two sides of the stop portion 11 in the extension direction of the guide slot 10b are both inclined surfaces, so that the stop portion 11 presses the elastic portion 23 into deformation.

[0079] In some embodiments, referring to FIG. 18, at least part of the inner wall of the accommodating cavity 20a defines the guide slot 10b, so that the structure is more compact.

[0080] In some embodiments, referring to FIG. 18, at least part of the inner wall of the accommodating cavity 20a forms the limiting portion 12, so that the structure is more compact.

[0081] A specific manner of implementing the electrical connection between the atomizer 30 and the power supply assembly 20 is not limited.

[0082] In some embodiments, referring to FIG. 6 to FIG. 8, FIG. 16 to FIG. 18, FIG. 22, and FIG. 23, the aerosol generating device includes a first pin 50 and an electric wire 34, the atomizer 30 is provided with a second mounting hole 30d, at least part of the first pin 50 is inserted in the second mounting hole 30d, the electric wire 34 is electrically connected to the atomizer 30, a part of the electric wire 34 is sandwiched between the inner wall of the second mounting hole 30d and the first pin 50, to electrically connect the electric wire 34 to the first pin 50, the end of the first pin 50 in the second direction is located on the side of the atomizer 30 in the second direction, the surface on the side of the power supply assembly 20 in the second direction is provided with a power supply contact, and the first pin 50 contacts the power supply contact, to electrically connect the first pin to the power supply contact.

[0083] At least part of the first pin 50 is made of a conductive material, to achieve conductivity. A specific type of the conductive material that is used is not limited, for example, copper.

[0084] Because at least part of the electric wire 34 is sandwiched between the inner wall of the second mounting hole 30d and the first pin 50, not only an electrical conduction is achieved between the electric wire 34 and the first pin 50, but also limitation is provided for the first pin 50 and the electric wire through a friction among the electric wire 34, the inner wall of the second mounting hole 30d, and the first pin 50, to maintain a stable electrical connection state between the electric wire and the first pin.

[0085] A part of the electric wire 34 may be inserted into the second mounting hole 30d in advance, and then the first pin 50 is pressed into the second mounting hole 30d, so that the electric wire 34 is sandwiched between the inner wall of the second mounting hole 30d and the first pin 50. Therefore, the fixing between the electric wire 34 and the first pin 50 does not need to be implemented through soldering or adhesion, thereby simplifying fitting steps of the atomizer 30.

[0086] In some embodiments, referring to FIG. 6 to FIG. 8, FIG. 16 to FIG. 18, FIG. 22, and FIG. 23, the atomizer 30 includes an atomizer housing 32 and an atomization assembly 33, the main storage cavity 30a is located at the atomization assembly 33, the atomization assembly 33 and the atomizer housing 32 define a first cavity 30b, and the electric wire 34 is at least partially located in the first cavity 30b.

[0087] In this way, a particular protection function can be provided for the electric wire 34.

[0088] In some embodiments, referring to FIG. 7 and FIG. 17, the end surface on the end of the first pin 50 in the second direction is flush with the end surface the end of the atomizer housing 32 in a second direction, to reduce a probability that the first pin 50 is damaged by collision during mounting and dismounting of the functional assembly 10. A specific position of the second mounting hole 30d is not limited.

[0089] In some embodiments, the atomizer housing 32 is provided with a second mounting hole 30d, and the second mounting hole 30d is in communication with the first cavity 30b and outside of the atomizer.

[0090] In some other embodiments, referring to FIG. 6 to FIG. 8, FIG. 16 to FIG. 18, FIG. 22, and FIG. 23, the atomizer housing 32 is provided with a first mounting hole 30c, the first mounting hole 30c is in communication with the first cavity 30b and outside of the atomizer 30, at least one of the atomization assembly 33 and the atomizer housing 32 is provided with a second mounting hole 30d, the second mounting hole 30d is located in the first cavity 30b, the first pin 50 is inserted in the first mounting hole 30c and the second mounting hole 30d, and the electric wire 34 is electrically connected to the atomization assembly 33.

[0091] The atomization assembly 33 is configured to convert the aerosol generating substrate into aerosols.

[0092] The electric wire 34 has conductivity, and has a flexible structure so as to flexibly bend the electric wire 34 based on a relative position relationship between an electrical connection location between the atomization assembly 33 and the electric wire and the second mounting hole 30d, thereby improving mounting adaptability.

[0093] In some embodiments, referring to FIG. 7, the first mounting hole 30c is located on the side of the atomizer housing 32 in the second direction, to reduce a distance with the power supply assembly 20, thereby facilitating the electrical connection of the first pin 50 to the power supply assembly 20.

[0094] In some embodiments, referring to FIG. 6, the atomization assembly 33 includes an atomization core 331, and the electric wire 34 is electrically connected to the atomization core 331, so that the power supply assembly 20, the electric wire 34, and the atomization core 331 form an electric path, to help the power supply assembly 20 provide electric energy to the atomization core 331.

[0095] In some embodiments, referring to FIG. 7 and FIG. 17, an extension direction of the first mounting hole 30c is the same as an extension direction of the second mounting hole 30d, the end of the second mounting hole 30d is open toward the first mounting hole 30c, and at least part of the first pin 50 may run through the first mounting hole 30c.

[0096] The extension direction of the first mounting hole 30c is a depth direction of the first mounting hole 30c. The extension direction of the second mounting hole 30d is a depth direction of the second mounting hole 30d.

[0097] In other words, in terms of a projection perpendicular to the extension direction of the first mounting hole 30c, at least part of a projection of the first pin 50 can completely coincide with a projection of the first mounting hole 30c or is smaller than the projection of the first mounting hole 30c. In this way, after the atomizer 30 is completely fitted, at least part of the first pin 50 may be inserted into the second mounting hole 30d from outside of the atomizer housing 32, and the inner wall of the first mounting hole 30c can provide guidance and limitation for insertion of the first pin 50, so that the first pin 50 can be accurately inserted into the second mounting hole 30d.

[0098] In some embodiments in which the atomization cavity 331a is in communication with the first cavity 30b, the atomizer housing 32 is provided with an air inlet hole 32a, and the air inlet hole 32a in communication with the first cavity 30b and outside of the aerosol generating device. It may be understood that, the functional assembly 10 and the power supply assembly 20 may be detachably connected, so that a joint exists between the functional assembly and the power supply assembly.

[0099] In some embodiments, referring to FIG. 7 and FIG. 17, the atomization assembly 33 is provided with an atomization cavity 331a, the atomization cavity 331a is in communication with the first cavity 30b, and the first pin 50 is hermetically attached to the inner wall of the first mounting hole 30c.

[0100] The first pin 50 is hermetically attached to the inner wall of the first mounting hole 30c, so that external air cannot easily enter the first cavity 30b through the first mounting hole 30c during inhalation of aerosols by the user, which helps form negative air pressure in the first cavity 30b, thereby helping air outside the aerosol generating device enter the first cavity 30b and then enter the atomization cavity 331a.

[0101] It may be understood that, liquids are formed after residual aerosols in the atomization cavity 331a condense, which flow into the first cavity 30b.

[0102] In some embodiments, interference fit is adopted between the second mounting hole 30d and the first pin 50, to fix a part of the electric wire 34 between the inner wall of the second mounting hole 30d and the first pin 50.

[0103] In some embodiments, in terms of a projection perpendicular to an extension direction of the atomization cavity 331a, a projection of the first pin 50 and a projection of the second mounting hole 30d are both located outside a projection of a communication position between the atomization cavity 331a and the first cavity 30b, to reduce a probability that condensates directly contact the first pin 50 and the connection position between the first pin 50 and the electric wire 34.

[0104] In some embodiments, referring to FIG. 3, FIG. 6, FIG. 16, and FIG. 22, the atomization assembly 33 is provided with an atomization cavity 331a, the atomization cavity 331a is in communication with the first cavity 30b, the atomizer 30 further includes a liquid absorbing member 35, and the liquid absorbing member 35 is located in the first cavity 30b.

[0105] Through the liquid absorbing member 35, a partial space in the first cavity 30b may be occupied, so that negative pressure can be formed in the first cavity 30b more quickly; and the liquid absorbing member 35 can absorb the condensates, thereby reducing a probability of corrosion of the electric wire 34 by the condensates and reducing a leakage risk of the condensates.

[0106] The liquid absorbing member 35 is provided therein with pores to absorb the aerosol generating substrate.

[0107] It may be understood that, the pores of the liquid absorbing member 35 may be pores that can be macroscopically identified by naked eyes, or may be pores that cannot be microscopically identified by naked eyes, as long as the pores can absorb the aerosol generating substrate through a capillarity action and allow airflows to pass through.

[0108] A specific form of the liquid absorbing member 35 is not limited, and is, for example, a fiber structure formed by braiding or twisting of chemical fiber such as batt, sponge, polyester, or chinlon.

[0109] It may be understood that, a material of the aerosol generating substrate relative to the liquid absorbing member 35 is a wetting liquid, so that the aerosol generating substrate can be attached to or absorbed by the liquid absorbing member 35.

[0110] In some embodiments, referring to FIG. 7, FIG. 17, and FIG. 23, the atomizer 30 includes an elastic fixing base 36, the elastic fixing base 36 is made of an elastic material, and the second mounting hole 30d runs through the elastic fixing base 36. Through elastic deformation of the elastic fixing base 36, an elastic action is generated on the inner wall of the second mounting hole 30d, which helps enhance a pressing action between the inner wall of the second mounting hole 30d and the first pin 50 on the electric wire 34, thereby improving stability of the electrical connection between the first pin 50 and the electric wire 34.

[0111] In some embodiments, the elastic fixing base 36 is arranged on the atomization assembly 33.

[0112] It may be understood that, the main storage cavity 30a and the atomization cavity 331a are isolated from each other.

[0113] In some embodiments in which the first mounting hole 30c is located on the side of the atomizer housing 32 in the second direction, referring to FIG. 3, FIG. 7, FIG. 16, and FIG. 17, the power supply assembly 20 includes a power supply housing 24, a power supply member 25, and a second pin 26, the power supply housing 24 is provided with a second cavity 24b and a fourth mounting hole 24a, the fourth mounting hole 24a is in communication with outside of the second cavity 24b and the power supply assembly 20, the fourth mounting hole 24a extends in the second direction, the power supply member 25 is located in the second cavity 24b, at least part of the second pin 26 is located in the second cavity 24b and is electrically connected to the power supply member 25, the second pin 26 is inserted in the fourth mounting hole 24a, the second pin 26 can stretch and contract in the second direction, and the second pin 26 can abut against the first pin 50 in the second direction.

[0114] Through contact between the first pin 50 and the second pin 26, an electrical connection is implemented, thereby implementing the electrical connection between the power supply assembly 20 and the atomizer 30. Through stretching and contraction of the second pin 26, the second pin 26 can be maintained in contact with the first pin 50, thereby helping maintain a stable electrical connection.

[0115] It may be understood that, a part of the second pin 26 forms a power supply contact.

[0116] Types of electronic components included in the power supply assembly 20 are not limited. For example, the power supply assembly includes a power supply member 25, a printed circuit board (PCB), and an air pressure sensor 28.

[0117] A specific type of the power supply member 25 is not limited. For example, the power supply member is a lithium battery.

[0118] In some embodiments, referring to FIG. 4, FIG. 5, FIG. 8, FIG. 16 to FIG. 18, FIG. 22, and FIG. 23, the functional assembly 10 is provided with an airflow channel and a first air pressure hole 10e, the outlet and the inlet of the airflow channel are both in communication with the outside of the aerosol generating device, the first air pressure hole 10e is in communication with the airflow channel and outside of the functional assembly 10, the power supply assembly 20 includes a power supply housing 24, an elastic mounting base 27, and an air pressure sensor 28, the power supply housing 24 is provided therein with a second cavity 24b and a third mounting hole, the third mounting hole is in communication with the second cavity 24b and outside of the power supply assembly 20, the elastic mounting base 27 is inserted in the third mounting hole, the elastic mounting base 27 is provided with a second air pressure hole 27a, a sensing area of the air pressure sensor 28 is located at the second air pressure hole 27a, and in a state in which the power supply assembly 20 is electrically connected to the atomizer 30, the elastic mounting base 27 is hermetically attached to the functional assembly 10, and the second air pressure hole 27a is in communication with the first air pressure hole 10e.

[0119] An airflow outside the aerosol generating device enters the airflow channel through the inlet of the airflow channel, and is mixed with an aerosol in the airflow channel, and then is discharged through the outlet of the airflow channel and enters the oral cavity of the user.

[0120] It may be understood that during inhalation by the user, air pressure in the airflow channel decreases, so that air pressure in the first air pressure hole 10e decreases, and air pressure in the second air pressure hole 27a decreases, so that the air pressure sensor 28 can sense a change of the air pressure, and then control the power supply member 25 to supply power to the atomizer 30.

[0121] The elastic mounting base 27 can elastically deform. The elastic mounting base 27 abuts against the functional assembly 10, so that the elastic mounting base 27 deforms, which reduces a probability that external air enters the second air pressure hole 27a through a joint between the elastic mounting base 27 and the functional assembly 10, and helps the air pressure sensor 28 more accurately sense negative air pressure generated in the second air pressure hole 27a from the inhalation by the user, thereby helping increase a response speed of the aerosol generating device.

[0122] A specific material of the elastic mounting base 27 is not limited, which is, for example, silicon or rubber.

[0123] In some embodiments, the air inlet hole 32a, the first cavity 30b, the atomization cavity 331a, and the air outlet channel 10a each form a part of the airflow channel.

[0124] In some embodiments, referring to FIG. 5 and FIG. 23, the elastic mounting base 27 includes an elastic skirt 271, the elastic skirt 271 surrounds an opening on the end of the second air pressure hole 27a, the elastic skirt 271 is inclined in the second direction and extends away from the opening of the second air pressure hole 27a, and the elastic skirt 271 is configured to be hermetically attached to the functional assembly 10. In this way, the elastic skirt 271 can deform more easily under an action force in the second direction, which helps improve sealing performance between the elastic mounting base 27 and the functional assembly 10.

[0125] In some embodiments provided with the atomizer housing 32, the atomization assembly 33, and the liquid absorbing member 35, referring to FIG. 16 and FIG. 17, the atomization assembly 33 and the atomizer housing 32 define the first cavity 30b, the first air pressure hole 10e is located at the atomizer housing 32 and is in communication with the first cavity 30b, the liquid absorbing member 35 is located in the first cavity 30b, and the first cavity 30b forms a part of the airflow channel.

[0126] In this way, the liquid absorbing member 35 in the first cavity 30b can absorb the condensates, which reduces a probability that the condensates enter the second air pressure hole 27a and contact the air pressure sensor 28, thereby helping increase a service life of the air pressure sensor 28.

[0127] In some embodiments, referring to FIG. 10, FIG. 11, and FIG. 22, the additional e-liquid tank 40 includes an e-liquid tank housing 42, a mounting plug 43, and an elastic sealing member 44, the e-liquid tank housing 42 is provided therein with a storage space, the side of the storage space is open, the mounting plug 43 covers an open position of the storage space, the mounting plug 43 is provided with a plugging channel, the plugging channel is in communication with the additional storage cavity 40a and outside of the additional e-liquid tank 40, the elastic sealing member 44 includes an annular portion 441 sand a blocking portion 442, the annular portion 441 is sandwiched between the mounting plug 43 and the e-liquid tank housing 42, the e-liquid tank housing 42, the mounting plug 43, and the elastic sealing member 44 jointly define the additional storage cavity 40a, the blocking portion 442 is connected to the annular portion 441, and the blocking portion 442 blocks a communication port between the plugging channel and the additional storage cavity 40a. A part of the atomizer 30 may be inserted into the plugging channel, to push the blocking portion 442 to detach to open the plugging channel, so that the main storage cavity 30a is in communication with the additional storage cavity 40a.

[0128] Therefore, a same part is used for both sealing the e-liquid tank housing 42 and the mounting plug 43 and blocking the plugging channel, which helps reduce a quantity of parts in the additional e-liquid tank 40, and helps reduce production and assembly costs.

[0129] In some embodiments, referring to FIG. 3 and FIG. 13, the external surface of the atomization assembly 33 is provided with an insertion column 332, the insertion column 332 extends in the first direction, the insertion column 332 is provided with a liquid inlet channel 332a running through the insertion column, the liquid inlet channel 332a is in communication with the main storage cavity 30a and the outside of the atomization assembly 33, and the insertion column 332 is configured to be inserted into the plugging channel to push the blocking portion 442 to open the plugging channel.

[0131] In some embodiments in which the functional assembly 10 is provided with the air outlet channel 10a, referring to FIG. 22, the outlet of the air outlet channel 10a is located on the side of the functional assembly 10 away from the power supply assembly 20 in the second direction.

[0132] The above arrangement helps reduce a probability that condensates flowing out from the air outlet channel 10a adhere to the power supply assembly 20.

[0133] In some embodiments, the functional assembly 10 is provided with an air inlet channel, the air inlet channel is in communication with the outside of the aerosol generating device, and the inlet of the air inlet channel is located on the side of the functional assembly 10 in the first direction.

[0134] The air inlet channel is used for an external airflow to enter the functional assembly 10, so as to mix with the aerosols in the atomization cavity 331a. In this way, the condensates in the atomization cavity can enter the air inlet channel.

[0135] The above arrangement helps reduce a probability that condensates flowing out from the air inlet channel adhere to the power supply assembly 20.

[0136] In some embodiments, referring to FIG. 3, the air inlet hole 32a forms a part of the air inlet channel, and the inlet of the air inlet hole 32a forms the inlet of the air inlet channel.

[0139] In some embodiments, referring to FIG. 8 and FIG. 9, the first air pressure hole 10e is located on the first surface 10f, and the third mounting hole is located on 20b. The above arrangement helps the elastic mounting base 27 to be more tightly attached to the first surface 10f, thereby improving a sealing effect for communication between the first air pressure hole 10e and the second air pressure hole 27a.

[0140] In some embodiments, the additional e-liquid tank 40 and the atomizer 30 may be detachably connected, to replace the additional e-liquid tank 40 with a new one after the aerosol generating substrate in the additional storage cavity 40a is exhausted.

[0141] It may be understood that in a state in which the additional e-liquid tank 40 and the atomizer 30 are disassembled, the additional storage cavity 40a is no longer in communication with the main storage cavity 30a.

[0142] A manner of implementing the detachable connection between the atomizer 30 and the additional e-liquid tank 40 is not limited. For example, referring to FIG. 11 and FIG. 12, one of the atomizer 30 and the additional e-liquid tank 40 is provided with an elastic snap 45, the other of the atomizer and the additional e-liquid tank is provided with a disassembly hole 30e, and the elastic snap 45 can be embedded into the disassembly hole 30e and abut against the inner wall of the disassembly hole 30e in a first direction, so as to connect the atomizer 30 to the additional e-liquid tank 40. The elastic snap 45 is detached from the disassembly hole 30e through elastic deformation, to separate the atomizer 30 from the additional e-liquid tank 40.

[0143] In some embodiments, referring to FIG. 1, FIG. 14, FIG. 20, and FIG. 24, the atomizer 30, the additional e-liquid tank 40, and the power supply assembly 20 may be detachably connected to each other, and a part of the external surface of any one of the three forms a part of the outer contour surface of the aerosol generating device.

[0145] During use of the aerosol generating device, a part of the external surface of any one of the atomizer 30, the additional e-liquid tank 40, and the power supply assembly 20 can be directly observed by the user. In this way, when the aerosol generating substrate in the additional storage cavity 40a is exhausted, or at least one of the atomizer 30, the additional e-liquid tank 40, and the power supply assembly 20 is damaged, a force is directly applied to one of the atomizer 30, the additional e-liquid tank 40, and the power supply assembly 20 that needs to be dismounted, so as to separate one of the atomizer, the additional e-liquid tank, and the power supply assembly from the other two, thereby facilitating a subsequent independent operation.
