DETAILED DESCRIPTION

[0033] It should be noted that the technical features in the embodiments of the utility model can be combined with each other without conflict, and the detailed description in the specific implementation should be understood as the explanation and description of the purpose of the embodiments of the utility model, and should not be regarded as improper limitation on the embodiments of the utility model.

[0034] In the description of the embodiments of the utility model, the first direction orientation or positional relationship is based on the attached drawings, and the arrow X shown in the drawings. Figure 2 、 Figure 4 、 Figure 6 、 Figure 7 and Figure 11 the orientation or positional relationship shown in the drawings.

[0035] It should be understood that these orientation terms are only for the convenience of describing the embodiments of the utility model and simplifying the description, and are not intended to indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the embodiments of the utility model.

[0036] The embodiments of the utility model provide an aerosol generating device for forming an aerosol by heating or the like to an aerosol generating substrate for a user to smoke.

[0037] Referring to Figure 1 、 Figure 2 、 Figure 9 and Figure 10The aerosol-generating device comprises an atomizer 10 and an additional oil tank 20.

[0038] The atomizer 10 comprises a mounting assembly 11, an atomizing core 12 and a first liquid storage member 13. The mounting assembly 11 is provided with an air outlet passage 11a and a mounting cavity 11b. The atomizing core 12 is arranged in the mounting cavity 11b and surrounded by the inner wall of the mounting cavity 11b to form a mounting space 11c. The air outlet passage 11a extends in a first direction and has an outlet communicating with the outside of the aerosol-generating device. The first liquid storage member 13 is arranged in the mounting space 11c and fluidly connected to the atomizing core 12.

[0039] The additional oil tank 20 is provided with an additional storage cavity 20a. The additional storage cavity 20a is located on the side of the mounting space 11c away from the outlet of the air outlet passage 11a in the first direction and can communicate with the mounting space 11c.

[0040] The atomizing core 12 can be in contact with the aerosol-generating substrate in the mounting space 11c and convert the aerosol-generating substrate into aerosol by heating or other methods. The aerosol enters the atomizing cavity 12a and is discharged from the aerosol-generating device through the air outlet passage 11a for the user to smoke.

[0041] The atomizing core 12 is fluidly connected to the first liquid storage member 13, which means that the aerosol-generating substrate in the first liquid storage member 13 can flow from the first liquid storage member 13 to the atomizing core 12.

[0042] The first liquid storage member 13 is provided with pores to be able to absorb the aerosol-generating substrate by capillary action. The fluid communication between the first liquid storage member 13 and the atomizing core 12 means that the fluid can flow from one to the other. The specific way to achieve fluid communication between the two is not limited, for example, the two are in direct contact, and for example, a channel is provided between the two to enable the fluid to pass through the channel to contact the two.

[0043] After the first liquid storage member 13 is in contact with the aerosol-generating substrate, the aerosol-generating substrate can be absorbed by the first liquid storage member 13 and stored in the space in the pores by capillary action. At least part of the pores are in communication with each other, so that the aerosol-generating substrate can pass through the first liquid storage member 13 and be delivered to the atomizing core 12 which is in fluid communication with the first liquid storage member 13. In this way, after the aerosol-generating substrate on the atomizing core 12 is consumed to a certain extent, the first liquid storage member 13 can supplement the aerosol-generating substrate to the atomizing core 12, which is also conducive to limiting the speed of supplementing the aerosol-generating substrate to the atomizing core 12 and reducing the probability of at least part of the atomizing core 12 being immersed in the aerosol-generating substrate affecting the user's smoking taste.

[0044] The additional storage cavity 20a is used to store the aerosol generating substrate. In a state where the additional storage cavity 20a is in communication with the mounting space 11c, the aerosol generating substrate in the additional storage cavity 20a can flow into the mounting space 11c to replenish the consumption of the aerosol generating device in the mounting space 11c, thereby prolonging the service life of the aerosol generating device.

[0045] The additional oil tank 20 and the atomizer 10 are in a separable configuration. That is, the relative positions of the two can be fixed by direct connection or indirect connection through other structural members to maintain the communication state between the additional storage cavity 20a and the mounting space 11c, or the additional oil tank 20 and the atomizer 10 can be separated to replace a new additional oil tank 20 after the aerosol generating substrate in the additional storage cavity 20a is consumed.

[0046] It can be understood that the amount of aerosol generating substrate that the first liquid storage member 13 can store is limited. In the case where the aerosol generating substrate in the additional storage cavity 20a is supplied to the mounting space 11c in excess, it is easy to cause the aerosol generating substrate stored in the first liquid storage member 13 to be oversaturated, which on the one hand, can cause part of the aerosol generating substrate to overflow from the first liquid storage member 13 and at least part of the atomizing core 12 to be immersed in the aerosol generating substrate.

[0047] During use of the aerosol generating device by the user, the outlet of the air outlet passage 11a is in communication with the oral cavity of the user, and the first direction is generally along the vertical direction. Therefore, the additional storage cavity 20a is located below the mounting space 11c. Under the action of gravity, the aerosol generating substrate in the additional storage cavity 20a is difficult to enter the mounting space 11c.

[0048] The present application provides an aerosol generating device, and the additional storage cavity 20a is located on the side of the mounting space 11c away from the outlet of the air outlet passage 11a, which is beneficial to limit the timing of the aerosol generating substrate in the additional storage cavity 20a entering the mounting space 11c, and is beneficial to the user to reduce the probability of the first liquid storage member 13 being in an oversaturated state of the aerosol generating substrate during use of the aerosol generating device, and is beneficial to control the rate of the atomizing core 12 absorbing the aerosol generating substrate within a reasonable range, and is beneficial to keep the taste of the user smoking aerosol stable and improve the user experience.

[0049] It can be understood that in the case where the user does not use the aerosol production device, the aerosol production device can be inverted, that is, the first direction is generally along the direction of gravity and the additional storage cavity 20a is located above the mounting space 11c, which is beneficial to the aerosol generating substrate in the additional storage cavity 20a flowing into the mounting space 11c under the action of gravity and being absorbed by the first liquid storage member 13 to replenish the consumption of the aerosol generating substrate in the first liquid storage member 13.

[0050] It can be understood that the pores of the first liquid storage member 13 can be macroscopically recognizable holes or microscopically unrecognizable holes, as long as they meet the requirements of absorbing the aerosol generating substrate by capillary action and allowing airflow to pass through.

[0051] It can be understood that due to the pores, the air bubbles in the installation space 11c can also pass through the first liquid storage member 13 via the pores that communicate with each other. That is, the pores in the first liquid storage member 13 form a channel that allows airflow to pass through and allows the aerosol generating substrate to flow through. In some embodiments, the installation assembly 11 further comprises a ventilation channel that communicates the installation space 11c and the outside of the aerosol generating device, which is conducive to the airflow outside the aerosol generating device entering the installation space 11c and then passing through the first liquid storage member 13 to supplement the additional storage cavity 20a, thereby reducing the probability of negative pressure being formed in the additional storage cavity 20a as the aerosol is consumed.

[0052] The specific form of the first liquid storage member 13 is not limited, such as cotton, sponge, fiber structure woven or twisted from polyester, nylon, etc.

[0053] It can be understood that the aerosol generating substrate is relative to the material of the first liquid storage member 13 as an infiltration liquid, so that the aerosol generating substrate adheres or absorbs to the first liquid storage member 13.

[0054] The specific way in which the atomizing core 12 is fluidly connected to the first liquid storage member 13 is not limited, for example, the atomizing core 12 is attached to the first liquid storage member 13.

[0055] In some embodiments, referring to Figure 2 The atomizing core 12 is provided with an atomizing cavity 12a, which is isolated from the installation space 11c and communicates with the air outlet channel 11a, so that the aerosol in the atomizing cavity 12a can be discharged from the atomizer 10 for the user to smoke. In other embodiments, a part of the surface of the atomizing core 12 forms a part of the inner wall of the installation space 11c for absorbing the aerosol generating substrate, and another part of the surface forms a part of the surface of the air outlet channel 11a, so that the aerosol can be discharged from the atomizer 10.

[0056] In some embodiments provided with the atomizing cavity 12a, referring to Figure 2 The atomizing cavity 12a extends in a first direction, and the first liquid storage member 13 surrounds and covers the circumferential side of the atomizing core 12 perpendicular to the first direction. In this way, the probability of the aerosol generating substrate entering the installation space 11c directly contacting the atomizing core 12 is reduced.

[0057] In some embodiments, referring to Figure 2At least one of the mounting assembly 11 and the auxiliary oil tank 20 is provided with an exchange channel 20e, which extends along a first direction and is located between and connects the auxiliary storage cavity 20a and the mounting space 11c.

[0058] It is possible that only the mounting component 11 has an exchange channel 20e; it is possible that only the auxiliary oil tank 20 has an exchange channel 20e; or it is possible that both the mounting component 11 and the auxiliary oil tank 20 have exchange channels 20e.

[0059] The exchange channel 20e extends directly along the first direction, which helps to shorten the flow path of the aerosol generation matrix into the installation space 11c and improve the replenishment efficiency of the aerosol generation matrix; it also helps to reduce the size of the exchange channel 20e, which helps to reduce the overall external outline size of the atomizer 10 and the auxiliary oil tank 20, making the structure of the aerosol generation device more compact.

[0060] It is understandable that if a user continuously and repeatedly inhales during the use of the aerosol generating device, the aerosol generating matrix in the first liquid storage unit 13 will be significantly reduced, which may have an adverse effect on the taste of the inhaled product.

[0061] In some embodiments, see Figure 2 , Figure 4 to Figure 6 The auxiliary oil tank 20 includes an oil tank shell 21 and a second liquid storage component 22. The auxiliary storage cavity 20a is located inside the oil tank shell 21. The second liquid storage component 22 is located inside the auxiliary storage cavity 20a. When the installation space 11c is in communication with the auxiliary storage cavity 20a, the first liquid storage component 13 and the second liquid storage component 22 are fluidly connected. The capillary attraction generated by the first liquid storage component is not less than the capillary attraction generated by the second liquid storage component.

[0062] The second liquid reservoir 22 is provided with pores to absorb aerosols and generate a matrix through capillary action.

[0063] The first liquid storage device 13 and the second liquid storage device 22 are fluidly connected. The capillary attraction generated by the first liquid storage device 13 is not less than that generated by the second liquid storage device 22. This facilitates the flow of the aerosol generation matrix absorbed from the additional storage cavity 20a in the second liquid storage device 22 into the first liquid storage device 13 under capillary action, thereby replenishing the consumption of the aerosol generation matrix in the first liquid storage device 13.

[0064] During the user's use of the aerosol generating device, a portion of the aerosol generating matrix in the additional storage chamber 20a is absorbed by the second liquid storage component 22. Under capillary action, it can overcome gravity and enter the first liquid storage component 13, thereby maintaining the amount of aerosol generating matrix in the first liquid storage component 13 within a certain range to maintain the stability of the user's taste when inhaling the aerosol.

[0065] The material of the first liquid storage member 13 can be the same as or different from the material of the second liquid storage member 22.

[0066] The specific manner in which the capillary attraction generated by the first liquid storage member 13 is not less than the capillary attraction generated by the second liquid storage member 22 is not limited.

[0067] For example, the material of the first liquid storage member 13 can be the same as the material of the second liquid storage member 22, and the porosity of the first liquid storage member 13 can be not greater than the porosity of the second liquid storage member 22.

[0068] The porosity refers to the percentage of the volume of pores in the material to the total volume of the material in a natural state.

[0069] In some embodiments, referring to Figure 2 , one end of the second liquid storage member 22 along the first direction abuts against the side inner wall of the additional storage cavity 20a away from the mounting space 11c, and the other end abuts against the first liquid storage member 13.

[0070] In this way, on the one hand, the additional storage cavity 20a away from the side inner wall of the mounting space 11c and the first liquid storage member 13 jointly limit the movement of the second liquid storage member 22 along the first direction, reducing the probability that the second liquid storage member 22 is no longer in fluid connection with the first liquid storage member 13 due to the shaking of the aerosol-generating device or other factors; on the other hand, as the aerosol-generating substrate in the additional storage cavity 20a is consumed, the second liquid storage member 22 can absorb the aerosol-generating substrate remaining at the bottom of the additional storage cavity 20a during the use of the aerosol-generating device by the user, improving the utilization rate of the aerosol-generating substrate in the additional storage cavity 20a.

[0071] In some embodiments, referring to Figure 4 to Figure 6 , the oil reservoir housing 21 further comprises an exchange channel 20e extending along the first direction and communicating with the additional storage cavity 20a, at least part of the second liquid storage member 22 is located in the exchange channel 20e, the exchange channel 20e can communicate with the mounting space 11c, and the opening for communicating with the mounting space 11c is a communication port 20f, and one end of the second liquid storage member 22 along the first direction is flush with the communication port 20f.

[0072] In this way, on the one hand, the communication port 20f can be sealed and packaged during separate transportation and packaging, reducing the probability of contamination of the second storage member by the outside world; on the other hand, the first liquid storage member 13 does not need to extend into the exchange channel 20e, facilitating the fluid connection between the first liquid storage member 13 and the second liquid storage member 22, and being conducive to reducing the installation difficulty.

[0073] In some embodiments, referring to Figure 2 , Figure 4 ,Figure 6 and Figure 10 The mounting assembly 11 is provided with a mounting hole 11e extending along the first direction, one end of the mounting hole 11e being in communication with the mounting space 11c and the other end being in communication with the outside of the atomizer 10. The oil tank shell 21 is provided with a mounting column 211 extending along the first direction at one end of the first direction. The exchange channel 20e is arranged in the mounting column 211 and forms a communication port 20f at the end away from the mounting space 11c. The mounting column 211 extends into the mounting hole 11e, so that the first liquid storage member 13 and the second liquid storage member 22 are fluidly connected.

[0074] Through the cooperation between the mounting column 211 and the mounting hole 11e, the guiding and restraining effects are achieved, which facilitates the installation and fixation of the atomizer 10 and the additional oil tank 20 and simultaneously realizes the fluid connection of the first liquid storage member 13 and the second liquid storage member 22.

[0075] In some embodiments, referring to Figure 4 to Figure 6 The second liquid storage member 22 fills the exchange channel 20e.

[0076] That is, in the projection plane perpendicular to the first direction, there is no gap between the second liquid storage member 22 and the inner wall of the exchange channel 20e.

[0077] In this way, the aerosol generating substrate flowing out of the additional storage cavity 20a needs to pass through the second liquid storage member 22, which is beneficial to limit the amount of aerosol generating substrate entering the mounting space 11c, thereby reducing the risk of the first liquid storage member 13 being oversaturated due to too much or too fast flow of the aerosol generating substrate into the mounting space 11c. At the same time, it is beneficial to keep the first liquid storage member 13 and the second liquid storage member 22 in contact, which is beneficial to keep the first liquid storage member 13 absorbing the aerosol generating substrate from the second liquid storage member 22, and is beneficial to reduce the risk of dry burning and other problems caused by the atomizer 12 failing to timely absorb an appropriate amount of aerosol generating substrate.

[0078] In some embodiments, referring to Figure 6 In the projection plane perpendicular to the first direction, the projection of the second liquid storage member 22 is located within the projection range of the exchange channel 20e.

[0079] In this way, on the one hand, it is convenient to assemble the second liquid storage member 22 into the oil tank shell 21 along the first direction during the production and assembly of the additional oil tank 20. On the other hand, it is beneficial to reduce the space occupied by the second liquid storage member 22 in the additional storage cavity 20a, thereby facilitating the additional storage cavity 20a to store more aerosol generating substrate and prolonging the service life.

[0080] In some embodiments, referring to Figure 2 The aerosol generating device further includes a power supply assembly 30 electrically connected to the atomizer 12 to provide electrical energy to the atomizer 12.

[0081] In some embodiments, referring to Figure 2 , the additional oil tank 20 is clamped between the atomizer 10 and the power supply assembly 30 along the first direction, thereby facilitating the reduction of the size of the aerosol generating device perpendicular to the first direction and facilitating the user to hold the aerosol generating device during use.

[0082] In some embodiments provided with the power supply assembly 30, referring to Figure 2 , Figure 4 to Figure 6 , the additional oil tank 20 further comprises an avoiding hole 20b penetrating along the first direction, the avoiding hole 20b being isolated from the additional storage cavity 20a, a portion of the atomizer 10 penetrating the avoiding hole 20b and being spaced from the inner wall of the avoiding hole 20b along the first direction to form a plug-in space 20c, the plug-in space 20c being open along one side of the first direction to form a plug-in port 20d, and a portion of the power supply assembly 30 being inserted into the plug-in space 20c through the plug-in port 20d and being clamped between the inner walls of the plug-in space 20c along the first direction.

[0083] During assembly, the avoiding hole 20b can guide and limit the relative movement between the additional oil tank 20 and the atomizer 10, thereby facilitating the communication between the additional storage cavity 20a and the mounting space 11c.

[0084] It can be understood that a portion of the inner wall of the plug-in space 20c is formed by the atomizer 10, and another portion of the inner wall of the plug-in space 20c is formed by the additional oil tank 20.

[0085] After a portion of the power supply assembly 30 is inserted into the plug-in space 20c, the portion of the power supply assembly 30 perpendicular to the first direction abuts against the portion of the atomizer 10 inserted into the avoiding hole 20b along the first direction, and the other portion of the power supply assembly 30 perpendicular to the first direction abuts against the inner wall of the avoiding hole 20b along the first direction. In this way, by clamping the portion of the power supply assembly 30 inserted into the plug-in space 20c by the atomizer 10 and the additional oil tank 20 respectively, the atomizer 10 and the power supply assembly 30 and the additional oil tank 20 and the power supply assembly 30 can inhibit the tendency of relative movement between each other through friction, thereby facilitating the communication between the additional storage cavity 20a and the mounting space 11c and the stable electrical connection between the atomizing core 12 and the power supply assembly 30.

[0086] In some embodiments, referring to Figure 2 , Figure 3 , Figure 7 , Figure 8 and Figure 10The mounting assembly 11 is provided with a connecting column 111 extending along the first direction at one end of the first direction, the connecting column 111 is arranged in the avoiding hole 20b, the connecting column 111 is provided with a connecting channel 111a, the connecting column 111 is provided with a fixing hole 111b perpendicular to the first direction, the fixing hole 111b is in communication with the plug-in space 20c and the connecting channel 111a, and the atomizer 10 further comprises a conductive wire 14, at least a part of the conductive wire 14 is arranged in the connecting channel 111a, one end of the conductive wire 14 is electrically connected with the atomizing core 12, and the other end of the conductive wire 14 is arranged in the fixing hole 111b to be electrically connected with the part of the power supply assembly 30 inserted into the plug-in space 20c.

[0087] The connecting channel 111a can be used at least for arranging the conductive wire 14. It can be understood that one end of the connecting channel 111a along the extending direction thereof is in communication with the mounting cavity 11b, so that the conductive wire 14 can extend into the mounting cavity 11b to be electrically connected with the atomizing core 12.

[0088] The conductive wire 14 is of a flexible structure, which is conducive to absorbing the force by the bending deformation of the conductive wire 14 in the case that the connecting column 111 is deformed by the force perpendicular to the first direction when the dimension of the connecting channel 111a along the first direction is large, thereby reducing the probability that the conductive wire 14 is disconnected from the power supply assembly 30 after being subjected to the force, and thus being conducive to maintaining the electrical connection between the conductive wire 14 and the power supply assembly 30.

[0089] The conductive wire 14 is arranged in the avoiding hole 20b, which is conducive to shielding and protecting the position of the conductive wire 14 for electrical connection by the additional oil tank 20, thereby reducing the probability that the conductive wire 14 is short-circuited by foreign matters.

[0090] The position of the end of the conductive wire 14 for electrical connection with the power supply assembly 30 can be constrained through the fixing hole 111b, thereby being conducive to improving the stability of the electrical connection between the conductive wire 14 and the power supply assembly 30.

[0091] In some embodiments, referring to Figure 2 and Figure 10 The mounting assembly 11 further comprises a first air inlet channel 11d, an outlet of the first air inlet channel 11d is in communication with the atomizing cavity 12a, and an inlet of the first air inlet channel 11d is in communication with the outside of the aerosol generating device, so that the gas outside the aerosol generating device enters the atomizing cavity 12a through the first air inlet channel 11d in the process of the user smoking the aerosol, and is discharged from the air outlet channel 11a after being mixed with the aerosol, for the user to smoke the aerosol.

[0092] In some embodiments, referring to Figure 2 and Figure 10The power supply assembly 30 is provided with a second air inlet channel 30a, which is in communication with the outside of the aerosol generating device, and the connecting channel 111a is open at one end in the first direction to communicate with the second air inlet channel 30a, and the connecting channel 111a forms part of the first air inlet channel 11d.

[0093] In this way, the connecting channel 111a realizes the functions of airflow and arrangement of the conductive wire 14, which is conducive to reducing other structures in the atomizer 10 to form the first air inlet channel 11d, and is conducive to making the structure of the aerosol generating device more compact.

[0094] In some embodiments, referring to Figure 10 A portion of the conductive wire 14 extends into the atomization cavity 12a to electrically connect with the atomization core 12.

[0095] In some embodiments, referring to Figure 8 The fixing hole 111b is open on one side in the first direction, so that the conductive wire 14 is inserted into the fixing hole 111b through the open position of the fixing hole 111b in the first direction during installation, which improves the installation convenience of the conductive wire 14.

[0096] In some embodiments, referring to Figure 3 and Figure 11 The power supply assembly 30 includes a power supply body and a plug-in sheet 32, the plug-in sheet 32 extends in the first direction, the plug-in sheet 32 is arranged on one side of the power supply body in the first direction and electrically connected with the power supply body, and a portion of the plug-in sheet 32 is inserted into the plug-in space 20c through the plug-in port 20d and electrically connected with the conductive wire 14.

[0097] The plug-in sheet 32 can not only form a conductive path to electrically connect the power supply body 31 with the conductive wire 14, but also can inhibit the relative movement trend between the atomizer 10 and the power supply assembly 30 and between the additional oil tank 20 and the power supply assembly 30 by friction, which is conducive to reducing the number of components in the aerosol generating device and simplifying the structure of the aerosol generating device; the arrangement of the plug-in sheet 32 is adapted to the disassembly and assembly operation mode of the power supply assembly 30 and the atomizer 10, which is convenient for user operation.

[0098] The specific type of the power supply body is not limited, such as lithium battery, silver-zinc battery, etc.

[0099] The specific material of the plug-in sheet 32 is not limited, such as copper, aluminum, etc.

[0100] In some embodiments, referring to Figure 3 and Figure 8The connecting column 111 is provided with a positioning groove 111c which is perpendicular to the first direction outer wall, the positioning groove 111c is open on one side which is perpendicular to the first direction and communicates with the plug-in space 20c, the positioning groove 111c communicates with the fixing hole 111b, and a part of the conductive wire 14 is located in the positioning groove 111c and is perpendicular to the first direction and is attached to the plug-in sheet 32.

[0101] That is, a part of the conductive wire 14 is clamped between the connecting column 111 and the plug-in sheet 32 which is perpendicular to the first direction. In this way, it is beneficial to increase the contact area between the conductive wire 14 and the plug-in sheet 32, and further beneficial to improve the connection stability between the two.

[0102] Some embodiments, referring to Figure 7 to Figure 10 The positioning groove 111c extends along the first direction, so that the extension direction of the part of the conductive wire 14 in the positioning groove 111c is along the first direction, so that the extension direction of the conductive wire 14 is the same as the insertion direction of the plug-in sheet 32, reducing the probability of the conductive wire 14 being twisted and deformed during the insertion process of the plug-in sheet 32, and reducing the risk of the conductive wire 14 being broken and damaged.

[0103] Some embodiments, referring to Figure 3 and Figure 8 The positioning groove 111c extends along the first direction away from the plug-in port, which is beneficial to keep the part of the conductive wire 14 in the positioning groove 111c stable in position and shape under the pushing force of the plug-in sheet 32 along the first direction during the insertion process of the plug-in sheet 32, and reduce the risk of the conductive wire 14 being damaged due to bending and twisting deformation.

[0104] Some embodiments, the number of the conductive wire 14 is at least two, at least one of which is electrically connected to the positive electrode of the power supply assembly 30, and at least another one of which is electrically connected to the negative electrode of the power supply assembly 30.

[0105] Some embodiments, referring to Figure 11 The number of the plug-in sheet 32 is at least two, at least one of which is electrically connected to the positive electrode of the power supply body 31, and at least another one of which is electrically connected to the negative electrode of the power supply body 31.
