DETAILED DESCRIPTION
[0046] The present application is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood.

For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.
[0047] Component numbers used herein, such as "first" and "second," are used solely to distinguish the components being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).
[0048] The end refers to the area at the end portion, which can be understood as an area with a certain length at the end portion, and is not limited to the end face.
[0049] In one embodiment, referring to Figures 1 and 12 , the aerosol generating device includes a device housing 1, a heating core assembly 2, a conductive member 4, an elastic portion 5, a power source 9, a power supply circuit 10 (only a portion of the power supply circuit 10 is shown in Figure 12 ), and a restricting structure 6. The heating core assembly 2, the elastic portion 5, the power source 9, and the power supply circuit 10 are all disposed within the device housing 1.
[0050] The device shell 1 has an atomization space 21. The heating core assembly 2 is used to heat the aerosol generating matrix, and the generated aerosol enters the atomization space 21. The power supply circuit 10 is used to connect the heating core assembly 2 and the power supply 9, and the power supply 9 supplies power to the heating core assembly 2. In order to improve the safety of the aerosol generating device during transportation, the power supply circuit 10 has a circuit breaker 1107 for cutting off the circuit. In one embodiment, as shown in Figure 12, the circuit breaker 1107 includes a first conductive contact 1101 and a second conductive contact 1102. The first conductive contact 1101 and the second conductive contact 1102 are in the power supply circuit 10, and the circuit breaker 1107 is formed between the first conductive contact 1101 and the second conductive contact 1102. The conductive member 4 is used to connect the first conductive contact 1101 and the second conductive contact 1102. Before the conductive member 4 connects the first conductive contact 1101 and the second conductive contact 1102, the power supply circuit 10 is always in a disconnected state.
[0051] The conductive member 4 is movably disposed within the device housing 1 and has a disconnected state and a connected state. In the disconnected state, the circuit breaker 1107 remains disconnected. In the connected state, the conductive member 4 is connected to the circuit breaker 1107 to connect the circuit breaker 1107. That is, the conductive member 4 connects the first conductive contact 1101 to the second conductive contact 1102. At this time, if other positions on the power supply circuit are not disconnected, the power supply circuit 10 is in a conductive state.
[0052] In order to keep the conductive member 4 in a disconnected state, the limiting structure 6 in the present application locks the conductive member 4. The limiting structure 6 is configured to limit the conductive member 4 to a disconnected state and keep the circuit breaker 1107 disconnected.
[0053] The elastic portion 5 is used to provide elastic force to the conducting member 4 . After the restriction of the restricting structure 6 is released, the conducting member 4 can move to the connected state under the elastic force of the elastic portion 5 .
[0054] The restricting structure 6 has a locked state and an unlocked state. In the locked state, the restricting structure 6 locks the conductive member 4 to prevent it from moving toward the connected state, maintaining the conductive member 4 in the disconnected state. In the unlocked state, the restricting structure 6 releases the restriction on the conductive member 4, allowing the conductive member 4 to move to the connected state under the action of the elastic portion 5.
[0055] The unlocking state of the limiting structure of the present application may be one state or multiple states that all satisfy the requirement of locking and holding the conducting member 4 .
[0056] When the conductive member 4 is disconnected, the circuit breaker 1107 disconnects the power supply circuit 10. This prevents the power supply circuit 10 from being accidentally activated during transportation, even if a switch on the power supply circuit 10 is accidentally activated. When the restraining structure 6 is locked, it maintains the position of the conductive member 4. When the aerosol generating device is to be used, the restraining structure 6 is unlocked, releasing the restraint on the conductive member 4. The elastic portion 5 pushes the conductive member 4 toward the connected state, at which point the circuit breaker 1107 is connected, and the power supply circuit 10 can operate normally.
[0057] In one embodiment, there is no need to re-open the circuit breaker 1107 after the first use. Therefore, the restriction structure 6 is a disposable restriction structure, which is used to unlock the aerosol generating device when it is first used. Disposable here means that the restriction structure 6 cannot be used a second time to restrict the conductive element to a disconnected state.
[0058] In one embodiment, at least a portion of the restriction structure 6 is an operating portion 64 located outside the device housing 1 , and the operating portion 64 is used to operate the restriction structure.
[0059] In one embodiment, the heating core assembly operates according to the frequency of the user's puffing, and the aerosol generating device includes a sensor module 120, which is used to sense the puffing state of the aerosol generating device. The sensor module 120 is connected to the power supply circuit 10. In response to the sensing result of the sensor module 120, the power supply circuit 10 can be connected or disconnected. When the sensor module 120 senses that the aerosol generating device is puffed, the power supply circuit 10 is connected in response to the sensing result of the sensor module 120. When the sensor module 120 senses that the aerosol generating device is not puffed, the power supply circuit 10 is disconnected in response to the sensing result of the sensor module 120. In one embodiment, the sensing result of the sensor module 120 can be an electrical signal sent after detecting the target data, or it can be an operation of directly disconnecting or connecting the power supply circuit 10 in response to the puffing result of the aerosol generating device. That is, the sensor module 120 can be both a sensor and an induction switch.
[0060] In one embodiment, the sensing module 120 is an air pressure sensor, which is used to sense the gas pressure in the atomization space 21. The air pressure sensor is connected to the power supply circuit 10. After the gas pressure in the atomization space 21 drops to a target value, the air pressure sensor sends a connection signal, and the power supply circuit 10 connects the circuit in response to the connection signal. When the gas pressure in the atomization space 21 does not drop to the target value, the power supply circuit 10 keeps the power supply circuit 10 disconnected in response to the air pressure sensor. In some other embodiments, in addition to the air pressure sensor, the sensing module 120 can also sense changes in resistance, capacitance, voltage, etc. caused by inhaling the aerosol generating device and thereby control whether to connect the power supply circuit 10.
[0061] In one embodiment, referring to Figures 1, 2 and 13, the air pressure sensor is a microphone 1201, which is located on the power supply circuit 10. When the aerosol generating device is inhaled, the microphone 1201 senses that the pressure in the atomization space 21 drops to a target value and then sends a signal, and the power supply circuit 10 is turned on in response to the signal.
[0062] In some other embodiments, the heating core component can also be controlled by manual switch control. The aerosol generating device includes a manual switch for controlling the on and off of the power supply circuit 10. At this time, there is no need to collect the pressure value of the atomization space 21. The power supply circuit 10 can be turned on or off as needed to start or stop heating the heating core component.
[0063] In one embodiment, referring to Figures 1 and 2 , the conductive member 4 includes a locking member 45 and a conductive portion 46 disposed on the locking member 45. The locking member 45 is an insulating member. The conductive portion 46 is used to connect the circuit breaker 1107, while the locking member 45 is used to cooperate with the restricting structure 6. The elastic force exerted by the elastic portion 5 on the conductive member 4 acts on the locking member 45. The restricting structure 6 locks the locking member 45, thereby restricting the conductive member to a disconnected state.
[0064] The locking member 45 and the conductive portion 46 are separate components for ease of processing. Furthermore, since the conductive portion 46 is made of a conductive material that is relatively costly, eliminating the need for conductive material in the locking member 45 reduces costs. In some other embodiments, the conductive member 4 can also be integrally molded, in which case the entire conductive member 4 is conductive. In some other embodiments, the locking member 45 and the conductive portion 46 are insulated.
[0065] 12 and 13 , the conductive portion 46 includes an elastic conductive sheet 461 , and the conductive portion 46 is connected to the circuit break 1107 via the conductive sheet 461 . The conductive sheet 461 has a contact point 4611 .
[0066] In one embodiment, the conductive portion 46 includes a conductive plate. The conductive sheet 461 and the conductive plate can be fixed together by integral molding, welding, crimping, or other methods. The two conductive sheets 461 on the conductive portion 46 are in conductive contact with the first conductive contact 1101 and the second conductive contact 1102, respectively, to connect the conductive portion 46 to the circuit break 1107 and establish electrical continuity between the first conductive contact 1101 and the second conductive contact 1102.
[0067] Please refer to Figures 4, 5, 14 and 15. In one embodiment, the conductive part 4 includes a positioning rod 44 extending along the movement direction of the conductive part 4, and the positioning rod 44 is arranged on the locking fitting 45. The conductive part 46 has a positioning hole 462 for the positioning rod 44 to pass through. In one embodiment, the positioning rod 44 and the positioning hole 462 are interference fit to achieve the fixation of the conductive part 46. In some other embodiments, the conductive part 46 can be fixed to the conductive part locking fitting 45 by bonding, welding or clamping. In one embodiment, please refer to Figures 4, 5 and 15, the locking fitting 45 passes through the conductive part 46, and the conductive part 46 has a through hole 463 for the locking fitting 45 to pass through.
[0068] Referring to Figures 1 and 12 , the aerosol generating device includes a mounting base 8 and a circuit board 110 secured to the mounting base 8. A first conductive contact 1101 and a second conductive contact 1102 are both located on the circuit board 110. In one embodiment, the circuit board 110 is secured to the underside of the mounting base 8. In one embodiment, referring to Figures 3 and 4 , the mounting base 8 includes at least two hooks 89 , which secure the circuit board 110 to the underside of the mounting base 8.
[0069] In one embodiment, referring to FIG. 12 , a first connection point 1103, a second connection point 1104, a third connection point 1105, and a fourth connection point 1106 are shown on the circuit board 110. One pin of the heating core assembly is electrically connected to the first connection point 1103, and the other pin is electrically connected to the second connection point 1104. One of the positive and negative electrodes of the power supply 9 is electrically connected to the third connection point 1105, and the other is electrically connected to the fourth connection point 1106. The third connection point 1105 is connected to the first connection point 1103.
[0070] The first conductive contact 1101 is connected to the fourth connection point 1106, and the second conductive contact 1102 is connected to the second connection point 1104. After the conductive portion 46 of the conductive member 4 is connected to the circuit break 1107, the first conductive contact 1101 and the second conductive contact 1102 are connected, thereby achieving electrical connection between the fourth connection point 1106 and the second connection point 1104. In one embodiment, the direction of the wires between the circuit board 110 and the heating core assembly 2 is consistent with the direction of the gas path.
[0071] In one embodiment, referring to Figures 1 and 2 , to facilitate user operation, the restriction structure 6 covers all or part of the air inlet 13 when in the locked state. Before unlocking, the restriction structure 6 covers all or part of the air inlet 13, making it easier for the user to understand that the aerosol generating device needs to be activated, thereby improving the user experience. In some other embodiments, the restriction structure may not cover the air inlet.
[0072] Furthermore, in one embodiment, referring to Figures 1 and 6 , the restriction structure 6 includes a locking plate 61, which covers the air inlet 13. The locking plate 61 has a larger coverage area and can be used in situations where the air inlet 13 is located in different locations. In addition, the locking plate 61 is easier for the user to identify. The locking plate 61 is detachably connected to the locking fitting 45 of the conductive member 4, making it more convenient to unlock the conductive member 4 through the locking plate 61. Removing the locking plate 61 can unlock the conductive member 4 and release the restriction on the conductive member 4. In one embodiment, one end of the locking plate 61 forms an operating portion for the user to operate the locking plate 61 to unlock it.
[0073] In some other embodiments, in addition to the locking piece 61, the restricting structure 6 can be any feasible method. For example, the restricting structure 6 can be connected to the locking fitting 45 of the conductive member 4 through a weak connection. When unlocking is required, the restricting structure 6 can be destructively separated from the conductive member 4. In another example, a portion of the conductive member 4 extends out of the device housing 1, and the restricting structure 6 is a tape that adheres and fixes the portion of the conductive member 4 extending out of the device housing 1. In another example, the restricting structure 6 can be a clamping member that is clamped and fixed to the locking fitting 45 of the conductive member 4. This method will be described in detail below. In another example, the restricting structure can include a sliding member assembled on the device housing, the sliding member can slide horizontally relative to the device housing, the sliding member hooks the conductive member inside the device housing, and when unlocking is required, the sliding member is pushed to separate the sliding member from the conductive member.
[0074] Furthermore, in order to facilitate the locking of the conductive part 4, please refer to Figures 1 and 16. The conductive part 4 has a restricted end 41. When the conductive part 4 is in a non-connected state, the restricted end 41 is locked by the restricting structure 6 and extends out of the device shell 1. When the conductive part 4 is in a connected state, the restricting structure 6 releases the lock on the restricted end 41, and the restricted end 41 returns to the device shell 1. The restricting structure 6 locks the restricted end 41 in the locked state, preventing the conductive part 4 from moving to the connected state. After the restricted end 41 extends out of the device shell 1, it is more convenient for the restricting structure 6 to lock the conductive part 4, and it is also convenient to unlock the conductive part 4. The retraction of the restricted end 41 does not affect the use of the aerosol generating device. In one embodiment, the restricted end 41 is at the end of the locking fitting 45.
[0075] In some other embodiments, the restricted end 41 may also always be in the device shell 1. In this case, the restricting structure 6 needs to enter the device shell 1 to lock the restricted end 41. For example, the restricted end 41 has a lock hole, and the restricting structure 6 includes a lock hook hung on the device shell 1. The lock hook hooks the lock hole to prevent the conductive part 4 from moving to the connected state. When unlocking is required, the lock hook can be removed from the restricted end 41. This embodiment requires sufficient operating space to be reserved on the device shell 1.
[0076] Furthermore, in one embodiment, referring to Figure 16 , the restricted end 41 has a latching hole 411 or a latching slot, into which the restricted structure 6 in the locked state is latched. In the locked state, the restricted structure 6 abuts against the restricted end 41 and the device housing 1, preventing the conductive member 4 from moving toward the connected state. In one embodiment, the restricted structure 6 utilizes a locking plate 61. In some other embodiments, the restricted structure 6 may utilize other structures, such as a locking rod or a locking block. In some other embodiments, the latching hole may be replaced by a latching slot.
[0077] In addition to the above-mentioned method of directly clamping the conductive part 4 through the holding structure, the conductive part 4 can also be clamped on the device shell 1. For example, in one embodiment, the conductive part 4 includes an elastic arm 42 and a holding structure 43. The holding structure 43 is at the end of the elastic arm 42. The device shell 1 has a conductive part lock hole 14, and the elastic arm 42 extends into the conductive part lock hole 14. The holding structure 43 is clamped on the device shell 1. The holding structure 43 and the device shell 1 are blocked to prevent the conductive part 4 from moving to the connected state. When the limiting structure 6 is in the locked state, it is blocked by the holding structure 43 to limit the bending and deformation of the elastic arm 42. When the limiting structure 6 is in the unlocked state, the elastic arm 42 can be elastically deformed to release the blocking relationship between the holding structure 43 and the device shell 1. The holding structure 43 is clamped on the device shell 1, including being clamped in the conductive part lock hole 14 or the edge of the outer opening of the conductive part lock hole 14.
[0078] Referring to Figure 4, in one embodiment, the retaining structure 43 is at the restricted end 41. When the conductive member 4 is in a disconnected state, the retaining structure 43 extends out of the device housing 1. The elastic arm 42 and the retaining structure 43 at the end of the elastic arm 42 are both part of the locking fitting 45.
[0079] Furthermore, to allow the conductive member 4 to automatically move to the connected state after the restraining structure 6 releases the restraint on the elastic arm 42, in one embodiment, referring to Figures 1 to 5 , at least one of the retaining structure 43 and the blocking portion of the device housing 1 that blocks the retaining structure 43 includes a guide slope that guides the elastic arm 42 to deform and release the retaining relationship with the device housing 1. In one embodiment, the guide slope can be an inclined surface, an arc surface, or a curved surface.
[0080] In one embodiment, referring to FIG4 , the retaining structure 43 on the elastic arm 42 is a retaining protrusion 431 having a guide slope 432. Accordingly, the outer opening of the conductive member locking hole 14 is flared, and the edge of the conductive member locking hole 14 has a guide slope 141. The guide slope 432 on the retaining protrusion 431 cooperates with the guide slope 141 at the edge of the outer opening of the conductive member locking hole 14. Under the action of the elastic force of the elastic portion 5, the elastic arm 42 can be deformed, thereby causing the retaining protrusion 431 to disengage from the retaining relationship with the edge of the opening of the conductive member locking hole 14, thereby unlocking the conductive member 4.
[0081] Further, please refer to Figures 3 to 5. At least one elastic arm 42 is a first elastic arm 421, and at least one elastic arm 42 is a second elastic arm 422. The limiting structure 6 includes a blocking portion 62 located between the first elastic arm 421 and the second elastic arm 422. The blocking portion 62 prevents the first elastic arm 421 and the second elastic arm 422 from approaching each other. The first elastic arm 421 and the second elastic arm 422 are arranged relative to each other, which is beneficial to the force balance of the conductive member 4. The conductive member 4 has less resistance during movement and is easier to unlock. In one embodiment, the holding structure 43 on the first elastic arm 421 is located on the side of the first elastic arm 421 facing away from the second elastic arm 422, and the holding structure 43 on the second elastic arm 422 is located on the side of the second elastic arm 422 facing away from the first elastic arm 421. Under the action of the blocking portion 62, the holding structures 43 on the elastic arms will not approach each other.
[0082] In one embodiment, referring to Figures 3 to 6 , the conductive member 4 has two elastic arms 42: a first elastic arm 421 and a second elastic arm 422. The restricting structure 6 is a locking plate. The locking plate 61 has two locking holes 63, each for the first elastic arm 421 and the second elastic arm 422 to enter. The portion between the two locking holes 63 is a blocking portion 62, which prevents the first elastic arm 421 and the second elastic arm 422 from approaching each other, thereby preventing the conductive member 4 from being unlocked. In one embodiment, the first elastic arm 421 and the second elastic arm 422 are both part of the locking member 45.
[0083] In one embodiment, referring to FIG2 , the conductive member locking hole 14 functions as the air inlet 13 that communicates with the atomizing space 21 and can supply air to the atomizing space 21. This allows for full utilization of the conductive member locking hole 14, resulting in smoother air intake for the device. In other embodiments, the conductive member locking hole 14 can also be sealed with the conductive member 4, preventing external air from entering the atomizing space 21.
[0084] In one embodiment, the aerosol generating device generates an aerosol using an atomizing substrate. The heating core assembly 2 includes an electrically heated atomizing element for heating the atomizing substrate. Referring to Figures 1 to 5 , the device housing 1 includes an oil storage space 11 for storing the atomizing substrate, which is heated and atomized to generate an aerosol. In other embodiments, the aerosol generating device can also heat a solid rod-shaped aerosol generating substrate.
[0085] The atomization space 21 is located within the heating core assembly 2, which has an oil inlet 22 for the atomized substrate. When the electrically heated atomizer is energized, it heats and atomizes the atomized substrate, generating an aerosol. Because external air must enter the atomization space 21 when drawing the atomization space 21, the device housing 1 has an air inlet 13 communicating with the atomization space 21. This allows external air to enter the atomization space 21 through the air inlet 13 to replenish the aerosol in the atomization space 21 when drawing the aerosol.
[0086] In order to facilitate the transportation of the aerosol generating device and prevent the oil in the oil storage space 11 from leaking out through the heating core assembly 2, the heating core assembly 2 in this application needs to be activated before the first use. Only after activation will the atomization space 21 of the heating core assembly 2 be connected to the oil storage space 11.
[0087] The heating core assembly 2 includes at least a dormant state and an awake state. In the dormant state, the oil inlet 22 is closed, and the atomized matrix cannot enter the atomizing space 21 through the oil inlet, thereby isolating the atomizing space 21 from the oil storage space 11. In the awake state, the oil inlet 22 is opened and communicated with the oil storage space 11, thereby communicating with the oil storage space 11, and the atomized matrix can enter the atomizing space through the oil inlet 22.
[0088] In order to activate the heating core assembly 2 and simplify the structure of the aerosol generating device, the heating core assembly 2 is on the movement path of the conductive part 4 from the connected state to the disconnected state. When the conductive part 4 moves from the disconnected state to the connected state, it can drive the heating core assembly 2 to move from the sleep state to the awakened state.
[0089] In this way, during transportation, the heating core assembly 2 is in a dormant state, the oil in the oil storage space 11 cannot flow into the heating core assembly 2, and the atomized matrix is not likely to leak through the atomization space 21. The limiting structure 6 can maintain the position of the conductive member 4 when it is locked. When the aerosol generating device needs to be used, the limiting structure 6 is unlocked to unlock the limiting structure 6, which can release the restriction on the conductive member 4. The conductive member 4 is driven to the connected state under the action of the elastic part 5, and the heating core assembly 2 is pushed to the awakened state. At this time, the atomization space 21 of the heating core assembly 2 is connected to the oil storage space 11, and normal atomization work can be performed.
[0090] In one embodiment, the conductive member 4 of the aerosol generating device is disposed on the lower side of the heating core assembly 2 and is capable of moving upward to a connected state. When the conductive member 4 moves upward from the disconnected state to the connected state, the heating core assembly 2 is driven to move from the dormant state to the awakened state.
[0091] The top of the device housing 1 has a suction hole 12 for the user to inhale the aerosol. The atomization space 21 communicates with the suction hole 12, allowing the aerosol generated in the atomization space 21 to be drawn through the suction hole 12. In one embodiment, the atomization space 21 extends vertically, with the upper end communicating with the suction hole 12 and the lower end allowing gas to enter the device housing 1 through the air inlet 13.
[0092] The limitations of directional words such as top, bottom, up, and down in this application are for ease of understanding. The description made when the aerosol generating device is in use is only used to reflect the relative positional relationship between the structures. When the aerosol generating device is in other postures, the directional words in this application should be understood after switching to the use state.
[0093] The conductive member 4 abuts the heating core assembly 2, and the aforementioned switching between the awake state and the dormant state is achieved by changing the abutting position of the conductive member and the heating core assembly. The heating core assembly 2 is provided with an oil inlet 22. In the dormant state, the oil inlet 22 is sealed, and the oil in the oil storage space 11 cannot flow into the heating core assembly 2.
[0094] In some other embodiments, the conducting member 4 and the heating core assembly 2 may also be fixedly connected or hinged.
[0095] In one embodiment, referring to Figures 1 and 14 , the locking member 45 contacts the heating core assembly 2, while the conductive portion 46 does not contact the heating core assembly 2 to prevent damage. When the conductive member 4 moves upward from the disconnected state to the connected state, the locking member 45 pushes the heating core assembly 2 upward to the awakened state.
[0096] The aerosol generating device includes a seal 3, which seals the bottom of the oil storage space 11. The heating core assembly 2 is sealed with the seal 3. Referring to Figures 1 and 2, when the heating core assembly 2 is in a dormant state, the oil inlet 22 is separated from the oil storage space 11 by the seal 3. Therefore, during transportation, the aerosolized substrate in the oil storage space 11 cannot enter the heating core assembly 2 through the oil inlet 22, and the aerosolized substrate is not easily leaked through the aerosol space 21 and the air inlet 13.
[0097] Regarding the oil storage space 11, the shape of the oil storage space 11 can be in any feasible manner, for example, the heating core component 2 passes through the oil storage space 11, and the oil storage space 11 is annular at this time. For another example, the oil storage space 11 can also be on one side of the heating core component 2.
[0098] Regarding the structure of the heating core assembly 2, in one embodiment, please refer to Figures 1, 2, 7 and 8. The heating core assembly 2 includes a component housing 23 and a first atomizer seat 24. The component housing 23 is fixed to the first atomizer seat 24. The side wall of the first atomizer seat 24 is provided with a first atomizer seat hole 241 that is connected to the atomization space 21. The heating core assembly 2 also includes a first oil-conducting cotton 25 and a second oil-conducting cotton 26. The first oil-conducting cotton 25 and the second oil-conducting cotton 26 are both made of porous materials, such as porous oil-absorbing cotton. There is an assembly inner frame 28 between the first oil-conducting cotton 25 and the second oil-conducting cotton 26. The heating core assembly 2 also includes a second atomizer seat 27, which is fixed to the bottom of the component housing 23 and is fixed to the bottom of the component inner frame 28. The electric heating atomizer is on the inner side of the second oil-conducting cotton 26. The atomized substrate enters the first oil-conducting cotton 25 through the oil inlet 22, then passes through the internal frame 28 of the assembly and enters the second oil-conducting cotton 26. After contacting the electrically heated atomizer, it is heated and atomized to produce an aerosol. The electrically heated atomizer can adopt any feasible form, such as a heating wire mesh or multiple parallel heating wires.
[0099] In one embodiment, referring to Figures 1, 2 and 11, the seal 3 is annular, and the through hole 31 in the center of the seal 3 is for the heating core assembly 2 to pass through. When the heating core assembly 2 is in a dormant state, the oil inlet 22 of the heating core assembly 2 is blocked by the hole wall of the through hole 31, thereby separating the oil storage space 11 from the oil inlet 22. The outer peripheral surface of the seal 3 is sealed with the inner wall surface of the device shell 1. In some other embodiments, there can also be multiple seals, such as a bottom plate at the bottom of the oil storage space, a seal at the joint between the bottom plate and the heating core assembly is sealed with the heating core assembly, and a seal at the joint between the bottom plate and the device shell does not contact the heating core assembly.
[0100] In one embodiment, referring to Figures 1 and 2, a lining plate 7 is mounted above the seal 3 to limit the deformation of the seal 3 into the oil storage space 11. The inner side of the side wall of the device housing 1 has a stop step to prevent the lining plate 7 from moving upward.
[0101] In the process of connecting the heating core assembly 2, both the heating core assembly 2 and the conductive member 4 need to move. In one embodiment, please refer to Figures 1 and 2. In order to make the heating core assembly 2 and the conductive member 4 move more smoothly, the mounting seat 8 has a mounting seat hole 81 extending up and down, the lower end of the heating core assembly 2 is inserted into the mounting seat hole 81, and the upper end of the conductive member 4 is inserted into the mounting seat hole 81. The mounting seat hole 81 can guide the lower end of the heating core assembly 2 to move upward, and can guide the upper end of the conductive member 4 to move upward, so that the conductive member 4 and the heating core assembly 2 move more smoothly. In one embodiment, the heating core assembly 2 is inserted into the mounting seat hole 81 and is slidably sealed with the mounting seat hole 81 through a sealing ring.
[0102] Regarding the form of the elastic portion 5, in one embodiment, please refer to Figures 1 and 2, the elastic portion 5 is a coil spring 50 located between the conductive member 4 and the device housing 1, and the coil spring 50 is in a compressed state when the conductive member 4 is in a disconnected state and a connected state.
[0103] The coil spring 50 is compressed when the heating core assembly 2 is in both the dormant and awake states. This allows the coil spring 50 to not only provide a force to the conductive member 4 but also, after activation, to continue exerting a certain force on the conductive member 4, maintaining the stability of the conductive member 4 and the heating core assembly 2. In some other embodiments, the coil spring 50 may be compressed only when disconnected. In some other embodiments, the elastic portion 5 may be made of elastic rubber, a leaf spring, or the like, in addition to the coil spring 50.
[0104] Regarding the installation of the coil spring 50, in one embodiment, please refer to Figures 1 and 2, the device shell 1 has a conductive part lock hole 14, and the conductive part 4 extends into the conductive part lock hole 14. The device shell 1 includes a positioning sleeve 15, one end of the coil spring 50 is sleeved on the positioning sleeve 15, and the other end is pressed against the conductive part 4. In this way, the coil spring 50 is not easy to move and is more stable. In some other embodiments, the number of coil springs 50 can be any number, such as more than two. In addition to being installed on the positioning sleeve 15, the coil spring 50 can also be processed into a positioning groove on the device shell 1, and one end of the coil spring 50 can be inserted and removed from the positioning groove. In one embodiment, the conductive part lock hole 14 passes through the positioning sleeve 15.
[0105] After the aerosol generating device is activated, the heating core assembly 2 may also leak oil outward through the air inlet channel during use. In order not to affect the user experience, in one embodiment, please refer to Figures 1, 2, 9 and 10. The bottom of the heating core assembly 2 is movably sealed with the mounting seat 8. The seal 3 is above the mounting seat 8. The heating core assembly 2 passes through the seal 3. A ventilation space 16 connected to the heating core assembly 2 is formed between the seal 3 and the mounting seat 8. The heating core assembly 2 passes through the ventilation space 16. The mounting seat 8 has an air inlet hole 82 connected to the ventilation space 16 and a collection tank 83 at the bottom of the ventilation space 16. The collection tank 83 is used to receive the atomized matrix leaked from the heating core assembly 2. The height of the air inlet hole 82 is higher than the collection tank 83.
[0106] In one embodiment, referring to Figures 1, 2, 9, and 10, a collection tank 83 includes an oil-absorbing cotton pad 84, which can absorb the atomized matrix onto the oil-absorbing cotton pad 84 to prevent splashing. In one embodiment, referring to Figures 1, 2, 9, and 10, the mounting base 8 includes a seat cover 85, the inner hole of which forms a mounting seat hole 81. The lower end of the heating core assembly 2 is inserted into the mounting seat hole 81 and slides with the mounting seat hole 81 in a guided sliding and sealing manner. The collection tank 83 is located on the periphery of the seat cover 85.
[0107] In one embodiment, referring to Figures 1 and 3 , the mounting base 8 includes an oil filling hole 86. A boss 87 is formed on the mounting base 8 for inserting the sealing member 3. The oil filling hole 86 extends through the boss 87 and communicates with the oil storage space 11. A sealing plug 88 is provided in the oil filling hole 86 to seal the oil filling hole 86 and prevent oil leakage.
[0108] In one embodiment, referring to Figures 1 and 11, the seal 3 includes a sleeve 32 that is sleeved on the upper portion of the mounting seat 8. After the sleeve 32 is sleeved on the upper portion of the mounting seat 8, the position of the seal 3 and the mounting seat 8 is more stable. In one embodiment, the seal 3 is a sealing silicone.
[0109] In one embodiment, referring to Figures 1, 2, and 13, microphone 1201 is located on one side of circuit board 110, and conductive portion 46 is located on the other side of circuit board 110. To facilitate installation of microphone 1201, mounting base 8 is provided with a mounting groove 810, into which microphone silicone 130 is installed, and microphone 1201 is inserted.
[0110] Referring to Figure 10 , the mounting base 8 is provided with a vent hole 811 that connects the atomizing space 21 with the microphone 1201. Through the vent hole 811, the microphone 1201 can sense the pressure in the atomizing space 21. To prevent the atomized matrix from leaking through the vent hole 811, a collection groove 83 is provided on the microphone silicone 130. The opening of the vent hole 811, facing away from the microphone 1201, is higher than the bottom of the collection groove 83. This prevents oil in the collection groove 83 on the mounting base 8 from leaking onto the microphone 1201.
[0111] In one embodiment, referring to FIG1 , the device housing 1 includes a first housing 17 and a second housing 18, which are fastened to each other. During assembly of the aerosol generating device, the seal 3, mounting base 8, and heating core assembly 2 are installed in the first housing 17, the conductive member 4, spring, and restraining structure 6 are installed in the second housing 18, and the first housing 17 and second housing 18 are then fastened to each other.
[0112] In one embodiment, the activation process of the aerosol generating device is as follows:
[0113] The conductive part 4 is in an unconnected state, and the locking piece 61 clamps the holding structure 43 of the elastic arm 42, limiting the deformation of the elastic arm 42. Since the locking piece 61 blocks the air inlet 13 at the bottom of the device shell 1, it is easier for the user to understand that the locking piece 61 needs to be removed and unlocked before using the aerosol generating device. After the locking piece 61 is pulled out, under the elastic force of the coil spring 50, the conductive part 4 moves toward the connected state and pushes the heating core assembly 2, causing the heating core assembly 2 to move toward the awakened state, completing the activation of the heating core assembly 2 and the conductive part 4. The conductive part 46 of the conductive part 4 is connected to the circuit break 1107, and the oil inlet of the heating core assembly 2 is connected to the oil storage space 11.
