Description
Technical Field

[0002] Aerosol-generating devices heat an aerosol matrix to generate an aerosol without burning it. Existing aerosol-generating devices typically utilize a liquid reservoir to store the aerosol matrix. During the injection of the aerosol matrix into the reservoir, the volume of air within the reservoir increases, ultimately retaining a large amount of air. Changes in ambient temperature can easily cause the volume of air within the reservoir to change, which in turn can cause aerosol matrix leakage due to the squeezing force exerted on the aerosol matrix.

In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. 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.
[0052] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.
[0053] 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).
[0054] See also Figure 1 An embodiment of the present application provides an aerosol generating device, comprising an aerosol generating device A and a control device B; wherein the control device B is mainly used to supply power to the aerosol generating device A to prompt the aerosol generating device A to heat the aerosol matrix stored inside the aerosol generating device A, thereby generating a usable aerosol.
[0055] Exemplarily, the control device B may be a collection of a circuit board, a battery cell, and other related components (such as buttons, display screens, indicator lights, and other components that play an information interaction role). The control device B may support the realization of all or part of the functions of the aerosol generating device, such as controlling the aerosol generating device A to start and stop heating, adjusting the heating power or heating mode of the aerosol generating device A, and displaying the status information of the aerosol generating device.
[0056] In some embodiments, the control device B and the aerosol generating device A are two relatively independent functional structures. By combining and assembling the control device B and the aerosol generating device A through detachable connection methods such as snap-on, magnetic attraction, and sleeve connection, a complete aerosol generating device ready for use can be formed.
[0057] In some embodiments, the aerosol generating device adopts an integrated structure. For example, the relevant functional components involved in the control device B and the relevant functional components involved in the aerosol generating device A are structurally integrated through the device housing to form an integrated aerosol generating device.
[0058] The following mainly introduces the aerosol generating device A. Other components of the aerosol generating device (such as the control device B) can be selected and designed with reference to the existing technology and will not be described in detail here.
[0059] It should be noted that the description of "aerosol matrix" is introduced in this article only to describe the aerosol generating device A more clearly and in detail, and does not mean that the aerosol matrix must be a component of the aerosol generating device A or the aerosol generating equipment.
[0060] That is to say, the aerosol matrix does not constitute a limitation on the aerosol generating device A of this embodiment. The aerosol matrix can be a component of the aerosol generating device A or a consumable material when the aerosol generating device A is used; and depending on the application scenario of the aerosol generating device A or the aerosol generating equipment, the aerosol matrix can be a liquid medium such as physiological saline, liquid medicine, liquid extract, or e-liquid.
[0061] See also Figures 2 to 10 The aerosol generating device A includes a liquid cup member 10, an isolating member 20, a heating member 30, a sealing member 40 and other functional components as needed, which are described in detail below.
[0062] See also Figures 2 to 5The liquid cup 10 has an internal space and an air flow channel 10a; wherein the air flow channel 10a is arranged along a preset path through the liquid cup 10, that is, the air flow channel 10a is equivalent to a channel space relatively independent of the internal space of the liquid cup 10, and the air flow channel 10a is mainly used to provide a path for guiding the air flow into the interior of the aerosol generating device A and carrying the generated aerosol out of the aerosol generating device A.
[0063] See also Figures 2 to 5 The partition 20 is movably disposed on the liquid cup 10. The partition 20 can be used to enclose the inner space of the liquid cup 10 into a liquid storage chamber 10b for storing the aerosol matrix; for example, see Figure 3 The isolation member 20 is sealed against the inner wall of the liquid cup member 10 all around, so that a liquid storage cavity 10 b independent of the air flow channel 10 a can be formed in the internal space of the liquid cup member 10 .
[0064] See also Figure 3 The isolation member 20 has a liquid injection hole 20a and an air leakage hole 20b. The liquid injection hole 20a and the air leakage hole 20b are respectively set through the isolation member 20 in the moving direction of the isolation member 20, so that the liquid injection hole 20a and the air leakage hole 20b respectively connect the liquid storage chamber 10b with the outside of the isolation member 20.
[0065] Thus, when the aerosol matrix is injected into the liquid storage chamber 10b through the liquid injection hole 20a, the air in the liquid storage chamber 10b will be discharged from the liquid storage chamber 10b through the air release hole 20b as the aerosol matrix is injected, thereby achieving the effect of simultaneously injecting liquid and exhausting air. This not only achieves a balance of the pressure difference between the inside and outside of the liquid storage chamber 10b, which is conducive to the smooth injection of the aerosol matrix into the liquid storage chamber 10b, but also effectively reduces the amount of air in the liquid storage chamber 10b and increases the amount of aerosol matrix injected.
[0066] See also Figures 2 to 5 The heating element 30 is disposed within the airflow channel 10a, which is in communication with the liquid storage chamber 10b. At least a portion of the heating element 30 covers the connection between the airflow channel 10a and the liquid storage chamber 10b. This connection between the airflow channel 10a and the liquid storage chamber 10b facilitates the entry of the aerosol substrate within the liquid storage chamber 10b into the heating element 30, allowing the heating element 30 to heat the aerosol substrate within the airflow channel 10a and generate an aerosol.
[0067] For one example, see Figure 2 、 Figure 8 and Figure 9The liquid cup component 10 includes a liquid storage cup 11 and an air guide tube 12; wherein, the liquid storage cup 11 is roughly a shell structure with a preset volume space, and the liquid storage cup 11 is provided with a first air guide channel 11b at the top end in the first direction, and the liquid storage cup 11 is provided with an assembly channel (not marked in the figure) at the bottom end in the first direction. The assembly channel and the first air guide channel 11b connect the interior and exterior of the liquid storage cup 11.
[0068] The air duct 12 is roughly a tubular structure with a preset length in the first direction. For the convenience of distinction and description, the two opposite ends of the air duct 12 in the first direction are defined as the first end and the second end; the air duct 12 is arranged inside the liquid storage cup 11, and the first end of the air duct 12 is sealed and connected to the first air duct channel 11b, and the isolation member 20 is arranged inside the liquid storage cup 11 through the assembly channel and is sleeved on the second end of the air duct 12.
[0069] By utilizing the structural coordination between the isolating member 20, the liquid storage cup 11 and the air duct 12, a liquid storage chamber 10b can be enclosed between the air duct 12, the isolating member 20 and the liquid storage cup 11; and the internal space of the air duct 12 can be used as an air flow channel 10a independent of the liquid storage chamber 10b, so that the air duct 12 or the opposite ends of the air flow channel 10a are kept in communication with the outside of the liquid storage cup 11; accordingly, a liquid inlet hole 10d is provided on the side wall of the air duct 12 for connecting the air flow channel 10a with the liquid storage chamber 10b, and the heating element 30 is arranged inside the air duct 12 (i.e., the air flow channel 10a) to cover the liquid inlet hole 10d.
[0070] Thus, the aerosol matrix stored in the liquid storage chamber 10b can enter the heating element 30 through the liquid inlet hole 10d to be heated by the heating element 30 to generate an aerosol; and the airflow outside the liquid cup 10 or the aerosol generating device A can carry the aerosol out of the aerosol generating device A from the first air guide channel 11b after entering the airflow channel 10a for use.
[0071] In some embodiments, the isolation member 20 may also be arranged at other positions of the liquid storage cup 11, for example, the assembly channel is arranged to pass through the side wall of the liquid storage cup 11 along a second direction perpendicular to or intersecting the first direction, and the assembly channel and the first air guide channel 11b are located on the same side or the same end of the shell 11 in the first direction; in this way, a liquid storage chamber 10b that is relatively independent of the air flow channel 10a can also be formed inside the liquid storage cup 11.
[0072] In some embodiments, the air duct 12 can be arranged outside the liquid storage cup 11, for example, the air duct 12 and the liquid storage cup 11 are arranged side by side in a second direction perpendicular to the first direction, and the internal space of the air duct 12 is used as the air flow channel 10a, and the liquid storage cup 11 and the isolation member 20 are used to form a liquid storage cavity 10b inside the liquid storage cup 11 that is connected to the air flow channel 10a; or, the air duct 12 and the liquid storage cup 11 adopt an integrated structure, that is, based on the selection of the material of the liquid cup member 10, the air duct 12 and the liquid storage cup 11 can be constructed into an integrated structure by injection molding, 3D printing, etc.; all these will not be elaborated here.
[0073] See also Figure 4 and Figure 5 The closure member 40 is detachably connected to the side of the isolation member 20 facing away from the liquid storage chamber 10b. It is primarily used to cooperate with the isolation member 20 to seal and store the aerosol matrix within the liquid storage chamber 10b. Specifically, after the aerosol matrix is injected into the liquid storage chamber 10b, the closure member 40 can be installed on the isolation member 20 to seal the liquid injection hole 20a and the air leakage hole 20b, thereby preventing the aerosol matrix in the liquid storage chamber 10b from leaking out of the liquid cup 10 through the liquid injection hole 20a and the air leakage hole 20b. In practice, the closure member 40 can be located outside the liquid cup 10, or it can be disposed inside the liquid cup 10 and exposed to the outside.
[0074] At the same time, when the closure member 40 closes the liquid injection hole 20a and the air leakage hole 20b, the closure member 40 can push the isolation member 20 toward the liquid storage chamber 10b, thereby discharging at least part of the air retained in the liquid storage chamber 10b into the air flow channel 10a (specifically, the heating member 30); this can further reduce the amount of air in the liquid storage chamber 10b, so that the liquid storage chamber 10b is filled with aerosol matrix.
[0075] Before the aerosol generating device A is used (e.g., before leaving the factory), the liquid cup 10, the spacer 20, and the heating element 30 may be assembled in advance, or the sealing element 40 may be detached from the structure formed by the liquid cup 10, the spacer 20, and the heating element 30; see Figure 3 By means of the liquid injection hole 20a and the air leakage hole 20b, during the process of injecting the aerosol matrix into the liquid storage chamber 10b, the air in the liquid storage chamber 10b can be discharged from the liquid storage chamber 10b through the air leakage hole 20b. In order to prevent the aerosol matrix from overflowing the liquid storage chamber 10b through the liquid injection hole 20a or the air leakage hole 20b, during the liquid injection stage, the liquid storage chamber 10b is usually not filled with the aerosol matrix, which results in a portion of air remaining in the liquid storage chamber 10b.
[0076] After priming is complete, refer to Figure 4 and Figure 5, the liquid injection hole 20a and the air leakage hole 20b are sealed by the sealing member 40; then, the sealing member 40 can be pressed to push the isolation member 20 toward the liquid storage chamber 10b, thereby squeezing the air retained in the liquid storage chamber 10b to flow to the connection point between the liquid storage chamber 10b and the air flow channel 10a (specifically, the liquid inlet hole 10d); in this way, the aerosol matrix can be squeezed into the heating element 30 with the help of air to achieve the core lubrication of the heating element 30, and this part of the air can be discharged from the liquid storage chamber 10b to the heating element 30 (or the air flow channel 10a), thereby achieving the effect of further reducing the air content in the liquid storage chamber 10b.
[0077] First, after some existing aerosol generating devices complete liquid injection, a large amount of air often remains in the liquid storage space. This part of air can easily expand in volume due to factors such as increased ambient temperature, thereby forming a squeezing effect on the aerosol matrix in the liquid storage space, and further causing problems such as aerosol matrix leakage. Compared with existing aerosol generating devices, the aerosol generating device A provided in the embodiment of the present application can achieve secondary exhaust treatment of the liquid storage chamber 10b, thereby effectively reducing the air content in the liquid storage chamber 10b. During the process of carrying, transporting, and storing the aerosol generating device A, the problem of aerosol matrix leakage caused by changes in ambient temperature or changes in air pressure inside and outside the liquid storage chamber 10b can be avoided.
[0078] Secondly, some existing aerosol generating devices require a core lubrication operation before use, which not only increases the user's education cost and the time cost of the user waiting for the core to be lubricated, but also if the aerosol generating device is used without completing sufficient core lubrication, it is easy to affect the quality of the aerosol due to core sticking; compared with the existing aerosol generating devices, the aerosol generating device A provided in the embodiment of the present application can directly fully lubricate the heating element 30 during the liquid injection process, which not only avoids the phenomenon of core sticking in the aerosol generating device A during use, but also does not require the user to activate or re-lubricate the aerosol generating device A, which can effectively improve the user experience of the aerosol generating device A.
[0079] Third, after the core of some existing aerosol generating devices is fully moistened (i.e., the atomizing core is fully absorbed by the aerosol matrix), it is easy for the user to have the visual impression that the liquid storage space is too large and the aerosol matrix content is too small. However, the aerosol generating device of this embodiment can present the visual impression that the liquid storage chamber 10b is full of aerosol matrix by secondary exhausting the liquid storage chamber 10b and moistening the core of the heating element 30 during the exhaust process, which can enhance the user experience.
[0080] It should be noted that Figure 3 The bold solid line with an arrow in the middle represents the approximate direction or path of the aerosol matrix injected into the liquid storage chamber 10b. Figure 3The bold dashed line with an arrow in the middle represents the approximate direction or path of the air discharged from the liquid storage chamber 10b. Figure 5 The bold solid line with an arrow in the middle represents the direction in which the closure member 40 pushes the isolation member 20. Figure 5 The bold dashed line with an arrow in the middle represents the approximate path or direction of the discharge of the residual air in the liquid storage chamber 10b.
[0081] For one example, see Figure 3 and Figure 5 For the convenience of distinction and description, the two cavity walls of the liquid storage cavity 10b opposite to each other in the extension direction of the air flow channel 10a are defined as the first cavity wall and the second cavity wall respectively; wherein, the connection point between the air flow channel 10a and the liquid storage cavity 10b can be arranged close to the first cavity wall, or close to the second cavity wall, or multiple connection points can be arranged close to the first cavity wall and the second cavity wall respectively.
[0082] Exemplarily, the top side wall of the liquid storage cup 11 in the first direction is constructed as a second cavity wall, and the isolation member 20 is placed on the second end of the air duct 12 and sealed against the inner wall of the liquid storage cup 11, so that the isolation member 20 can be constructed as a first cavity wall or a part of the first cavity wall; wherein, the liquid inlet hole 10d is arranged close to the isolation member 20 or the first cavity wall.
[0083] In this way, after the closure member 40 closes the liquid injection hole 20a and the air leakage hole 20b, the aerosol generating device A can be positioned along the extension direction of the air flow channel 10a (for example, upright or inverted), so that the connection between the air flow channel 10a and the liquid storage chamber 10b (specifically, the liquid inlet hole 10d) is at a relatively high or highest position in the liquid storage chamber 10b, which can also be understood as making the liquid level in the liquid storage chamber 10b below the liquid inlet hole 10d; then, when the closure member 40 pushes the isolation member 20 toward the side of the liquid storage chamber 10b, the air retained in the liquid storage chamber 10b can be directly discharged from the liquid inlet hole 10d to the air flow channel 10a or the heating element 30, and it is not easy for the aerosol matrix to leak due to being squeezed into the heating element 30 by excessive air.
[0084] In addition, by arranging the liquid inlet 10d and the isolation member 20 on the same end side of the air flow channel 10a (or the air guide tube 12), after the liquid injection is completed, there is no need to turn or adjust the orientation of the entire aerosol generating device A. The air retained in the liquid storage chamber 10b can be directly discharged to the air flow channel 10a or the heating element 30 by pushing the isolation member 20; this can adapt to the user's operating habits and improve the convenience and comfort of operating the aerosol generating device A.
[0085] In other embodiments, the spacer 20 can also be configured as a wall other than the first and second walls of the liquid storage chamber 10b. For example, a mounting channel can be provided through the side wall of the liquid storage cup 11 in the second direction, and the spacer 20 can be installed within the mounting channel. In this way, when the spacer 20 is pushed and moved, the volume of the liquid storage chamber 10b is reduced, creating a squeezing effect on the aerosol matrix, thereby expelling air retained in the liquid storage chamber 10b through the aerosol matrix to the heating element 30 or the airflow channel 10a.
[0086] For one example, see Figure 2 、 Figure 8 and Figure 9 The liquid cup 10 also includes a sealing sleeve 13, which can be a tubular structure made of soft materials such as silicone. The sealing sleeve 13 is fixed to the inside of the liquid storage cup 11 (for example, inserted and fixed in the first air guide channel 11b of the liquid storage cup 11), and the first end of the air guide tube 12 is inserted into the sealing sleeve 13 in an interference fit manner; at the same time, the isolation member 20 is sleeved and fixed on the second end of the air guide tube 12.
[0087] First, the sealing sleeve 13 establishes a sealed connection between the air duct 12 (or the air flow channel 10a) and the liquid storage cup 11 (specifically, the first air duct 11b), thereby preventing the aerosol matrix in the liquid storage chamber 10b from leaking from the connection between the air duct 12 and the liquid storage cup 11.
[0088] Secondly, when the sealing member 40 pushes the isolating member 20 to move, the isolating member 20 can drive the air guide tube 12 (together with the heating member 30) to move synchronously relative to the sealing sleeve 13 and the liquid storage cup 11, thereby adjusting the position of the liquid inlet hole 10d in the liquid storage chamber 10b, so that the air retained in the liquid storage chamber 10b can be smoothly discharged to the air flow channel 10a or the heating member 30 through the liquid inlet hole 10d.
[0089] Thirdly, the isolation element 20 and the heating element 30 are assembled together by the air guide tube 12, so that the aerosol generating device A can be easily disassembled and maintained.
[0090] In other embodiments, the air duct 12 may also be fixedly connected to the sealing sleeve 13, or the air duct 12 and the liquid storage cup 11 may adopt an integrated structure to omit the sealing sleeve 13; and the isolation member 20 may be movably mounted on the second end of the air duct 12; in this way, by pushing the isolation member 20 to move, the volume of the liquid storage chamber 10b may also be adjusted to discharge the air retained in the liquid storage chamber 10b.
[0091] For one example, see Figure 8 、 Figure 9 and combined Figures 4 to 7The closure member 40 has a first sealing structure 40a and a second sealing structure 40b; the first sealing structure 40a and the second sealing structure 40b are each protruding from the surface of the closure member 40 facing the isolation member 20 along the moving direction (for example, the first direction) of the isolation member 20; illustratively, the first sealing structure 40a can be a columnar structure that is adapted to the size and shape of the injection hole 20a, and the second sealing structure 40b can be a columnar structure that is adapted to the size, shape, etc. of the air leakage hole 20b.
[0092] Thus, the first sealing structure 40a can be inserted into the liquid injection hole 20a in a positional manner (for example, inserted into the liquid injection hole 20a in an interference fit manner), and the second sealing structure 40b can be inserted into the liquid injection hole 20b in a positional manner (for example, inserted into the air leakage hole 20b in an interference fit manner), thereby achieving a sealed closure of the liquid injection hole 20a and the air leakage hole 20b, and preventing the aerosol matrix in the liquid storage chamber 10b from leaking to the outside of the aerosol generating device A through the isolation member 20.
[0093] In other embodiments, other suitable structural forms may also be adopted so that the closure member 40 can seal and close the liquid injection hole 20a and the air leakage hole 20b; for example, a side of the isolation member 20 facing the closure member 40 is provided with a sinking structure, and the ports of the liquid injection hole 20a and the air leakage hole 20b are both located in the sinking structure; correspondingly, a side of the closure member 40 facing the isolation member 20 is provided with a protruding structure that can be inserted into the sinking structure in position; thereby, the liquid injection hole 20a and the air leakage hole 20b are sealed and closed in the form of a cover.
[0094] For one example, see Figure 2 、 Figure 6 、 Figure 7 、 Figure 9 and Figure 10 The isolation member 20 also has a third sealing structure 20c; the third sealing structure 20c is arranged around the moving axis of the isolation member 20 and protrudes from the outer peripheral surface of the isolation member 20; for example, the third sealing structure 20c is an annular rib structure protruding from the outer peripheral surface of the isolation member 20, and for another example, the third sealing structure 20c is a sealing ring that is sleeved and fixed on the isolation member 20.
[0095] The third sealing structure 20c can be sealed against the inner wall of the liquid cup 10 (specifically, the channel wall of the assembly channel) all around, thereby achieving sealed isolation between the liquid storage chamber 10b and the outside of the liquid cup 10, so as to prevent the aerosol matrix in the liquid storage chamber 10b from leaking out from the peripheral side of the isolation member 20.
[0096] For one example, see Figure 2 、 Figure 6 、 Figure 7 and Figure 9The closure member 40 has a fourth sealing structure 40c, which can be an annular rib structure protruding from the outer peripheral surface of the closure member 40 around the moving axis of the isolation member 20, or a sealing ring sleeved and fixed on the closure member 40.
[0097] The fourth sealing structure 40c can make the closure 40 and the inner wall of the liquid cup 10 (specifically, the channel wall of the assembly channel) seal against each other all around; thereby, all or at least part of the closure 40 can be detachably inserted into the interior of the liquid cup 10 in an interference fit manner, and the structural gap between the peripheral surface of the closure 40 and the liquid cup 10 can be eliminated, further preventing the aerosol matrix from leaking from the side where the closure 40 and the isolation member 20 are located.
[0098] For one example, see Figure 6 and Figure 7 The isolation member 20 has a first positioning structure 20d, which is protruding from the outer peripheral surface of the isolation member 20; accordingly, the inner wall of the liquid cup member 10 is provided with a second positioning structure 10e; the first positioning structure 20d and the second positioning structure 10e are arranged opposite to each other in the moving direction (for example, the first direction) of the isolation member 20.
[0099] For example, see Figure 2 The isolating member 20 includes a separator 21 and an annular steel sheet 22. The separator 21 is mounted on and fixed to the second end of the air duct 12, and is sealed against the inner wall of the liquid storage cup 11. For example, a third sealing structure 20c provided on or formed on the separator 21 is sealed against the inner wall of the liquid storage cup 11 around the entire perimeter. Thus, the separator 21 encloses the internal space of the liquid cup 10 into a liquid storage chamber 10b. The annular steel sheet 22 is mounted on and fixed to the separator 21, serving as the first positioning structure 20d of the isolating member 20. Accordingly, please refer to Figure 9 A step surface structure is provided on the inner wall of the liquid storage cup 11 to serve as a second positioning structure 10e.
[0100] Of course, the second positioning structure 20d can also be a protruding structure provided on the outer peripheral surface of the isolating member 20 around the moving axis of the isolating member 20. For example, the annular steel sheet 22 is omitted, and the second positioning structure 20d and the partition seat 21 are an integrated structure.
[0101] Thus, when the closure member 40 pushes the isolating member 20 to a predetermined position, the first positioning structure 20d abuts against the second positioning structure 10e, thereby preventing the isolating member 20 from further moving toward the liquid storage chamber 10b. This prevents the volume of the liquid storage chamber 10b from being overly compressed, preventing the aerosol matrix in the liquid storage chamber 10b from being excessively squeezed into the heater 30 or the airflow channel 10a and leaking.
[0102] For one example, see Figures 8 to 10 A guiding structure is further provided between the isolating member 20 and the liquid cup member 10. For example, the outer peripheral surface of the isolating member 20 (specifically, the separating seat 21) is provided with a first guiding structure 20e along the moving direction of the isolating member 20, and the inner wall of the liquid cup member 10 (specifically, the liquid storage cup 11) is provided with a second guiding structure 10f extending along the moving direction of the isolating member 20; wherein, the first guiding structure 20e and the second guiding structure 10f can be a sliding groove structure and a sliding rail structure that are slidably matched.
[0103] In this way, through the cooperation of the first guide structure 20e and the second guide structure 10f, when the closure member 40 pushes the isolation member 20 to move, it can guide the isolation member 20 to ensure that the isolation member 20 can move smoothly and steadily toward the side of the liquid storage chamber 10b to a preset position (for example, the position where the first positioning structure 20e and the second positioning structure 10e abut each other).
[0104] For some examples, see Figure 2 、 Figure 8 and Figure 9 A locking structure is provided between the closure member 40 and the liquid cup member 10. For example, a first locking structure 40d is provided on the outer peripheral surface of the closure member 40, and a second locking structure 10g is provided on the liquid cup member 10 (specifically, the inner wall of the liquid storage cup 11). The first locking structure 40d and the second locking structure 10g can be a snap-fit structure, a magnetic structure, etc. that are aligned with each other.
[0105] The locking structure can restrict and fix the closure member 40 in a position where the first positioning structure 20e and the second positioning structure 10e are kept in contact with each other, so that the aerosol generating device A can maintain structural stability after the secondary exhaust. At the same time, it also provides conditions for removing the closure member 40 so that the aerosol matrix in the liquid storage chamber 10b can be replenished after the aerosol matrix is exhausted.
[0106] For one example, see Figure 2 and Figure 4The heating element 30 includes a heating body 31, an outer adsorption layer 32, an inner sleeve 33 and an inner adsorption layer 34. The inner sleeve 33 can be a tubular structure with an open side wall. The outer adsorption layer 32 is sleeved or wrapped on the outer peripheral side of the inner sleeve 33, and the inner adsorption layer 34 covers the opening of the inner sleeve 33 and is arranged on the inner peripheral side of the inner sleeve 33; that is, the outer adsorption layer 32, the inner sleeve 33 and the inner adsorption layer 34 can be sleeved in sequence from the outside to the inside; when the heating element 30 is assembled in the air flow channel 10a, the outer adsorption layer 32 is clamped and fixed between the inner sleeve 33 and the channel wall of the air flow channel 10a in the form of covering the connection between the air flow channel 10a and the liquid storage chamber 10b, specifically, the outer adsorption layer 32 covers the liquid inlet 10d and is clamped and fixed between the inner sleeve 33 and the air guide tube 12.
[0107] Among them, the outer adsorption layer 32 and the inner adsorption layer 34 can be tubular structures that are wound or prefabricated with materials with capillary force such as porous materials and limiting materials. For example, the materials of the outer adsorption layer 32 and the inner adsorption layer 34 are porous ceramics, cotton fibers, metal fibers, non-woven fabrics, etc.
[0108] The outer adsorption layer 32 can realize ventilation between the air flow channel 10a and the liquid storage chamber 10b, so as to guide the aerosol matrix in the liquid storage chamber 10b into the inner adsorption layer 34, and based on the cooperation between the outer adsorption layer 32 and the inner adsorption layer 34, the liquid inlet speed, ventilation speed, etc. can be controlled to avoid leakage of the aerosol matrix from the heating element 30; in addition, when the sealing member 40 pushes the isolation member 20 to move, the inner adsorption layer 34 and the outer adsorption layer 32 can provide support for discharging the air retained in the liquid storage chamber 10b, so that the air squeezes the aerosol matrix into the heating element 30 during the process of discharging the liquid storage chamber 10b, so as to fully infiltrate the inner adsorption layer 34 and the outer adsorption layer 32, thereby achieving the purpose of core moistening.
[0109] The heating element 31 is arranged in contact with the inner adsorption layer 34. By establishing an electrical connection between the heating element 31 and the control device B, the heating element 31 can be caused to generate heat to heat the aerosol matrix absorbed by the atomized inner adsorption layer 34, thereby generating an aerosol; for example, the heating element 31 adopts a columnar structure or a sheet structure, and the heating element 31 is inserted or buried inside the inner adsorption layer 34; for another example, the heating element 31 adopts a mesh structure, and the heating element 31 is attached and fixed to the inner wall of the inner adsorption layer 34.
[0110] In other embodiments, the heating element 30 may also adopt other suitable structures, for example, the inner adsorption layer 34 and the outer adsorption layer 32 are configured as an integrated structure; details will not be given here.
[0111] For one example, see Figures 2 to 5 、 Figure 8 and Figure 9The isolating member 20 and the sealing member 40 are disposed at one end of the liquid cup 10 in the direction of the airflow channel 10b. For example, the isolating member 20 is secured to the second end of the air duct 12, while the sealing member 40 is located on the side of the isolating member 20 facing away from the liquid storage chamber 10b. The heating member 30 includes a plurality of first electrodes 30a, which may be leads connected to the heating element 31. The first electrodes 30a extend from the second end of the air duct 12 out of the airflow channel 10a and are secured to the isolating member 20 (specifically, the separator 21).
[0112] Correspondingly, the closing member 40 has a plurality of second electrodes 40e, which can pass through and be fixed to the columnar structure provided on the closing member 40 along the moving direction of the isolating member 20; when the closing member 40 closes the injection hole 20a and the air leakage hole 20b, the first electrode 30a and the second electrode 40e correspond one to one and are electrically contacted.
[0113] Thus, by utilizing the one-to-one correspondence and electrical contact relationship between the first electrode 30a and the second electrode 30e, the closure member 40 can be used as a carrier for electrically connecting the aerosol generating device A (specifically, the heating member 30) to an external power source (such as the control device B), so as to provide support for starting and stopping heating, adjusting the heating mode or heating power, etc. of the heating member 30; at the same time, based on the detachable connection relationship between the closure member 40 and the isolation member 20, during the process of filling the aerosol generating device A with liquid, the heating member 30 can be ensured to be in a power-off state, thereby avoiding problems such as misstarting or dry burning of the aerosol generating device A.
[0114] For some examples, see Figure 2 、 Figure 9 and Figure 10 The isolation member 20 has a plurality of docking holes 20f, which are arranged on the side of the isolation member 20 facing the closing member 40 along the moving direction of the isolation member 20 (for example, the docking holes 20f are arranged on the side of the partition seat 21 facing the closing member 40), and the plurality of docking holes 20f, the plurality of first electrodes 30a and the plurality of second electrodes 40e correspond one to one; wherein, one end of the first electrode 30a leading out of the airflow channel 10a is fixed in the corresponding docking hole 20f.
[0115] When the closure member 40 seals the liquid injection hole 20a and the air leakage hole 20b (for example, the first sealing structure 40a is inserted into the liquid injection hole 20a, and the second sealing structure 40b is inserted into the air leakage hole 20b), the second electrode 40e can be simultaneously inserted into the corresponding docking hole 20f to electrically contact the corresponding first electrode 30a. This not only provides structural space for the first electrode 30a and the second electrode 40e via the docking hole 20f to ensure the stability of the electrode connection, but also, based on the arrangement of the docking hole 20f, the liquid injection hole 20a, and the air leakage hole 20b on the isolation member 20, provides a foolproof positioning function for the closure member 40, allowing the closure member 40 to quickly and easily seal the liquid injection hole 20a and the air leakage hole 20b, and establish an electrical connection with the heating element 30.
[0116] For one example, see Figure 2 and Figure 8 The closing member 40 includes a support seat 41 and a liquid absorbing member 42; wherein the support seat 41 is detachably connected to the isolation member 20, and is used to seal and close the liquid injection hole 20a and the air leakage hole 20b, and to push the isolation member 20 to move; for example, the first sealing structure 40a, the second sealing structure 40b, the fourth sealing structure 40c, the first locking structure 40d and the second electrode 40e are arranged on the support seat 41; the support seat 41 has an air guide channel (for the convenience of distinction and description, the air guide channel is defined as the second air guide channel 40f) and a drainage structure 40g that connects the second end of the air guide channel 12 with the outside of the liquid storage cup 11, and the drainage structure 40g is located on the side of the second air guide channel 40f close to the air guide tube 12 (or the air flow channel 10a).
[0117] The absorbing liquid 42 is disposed within the support base 41, surrounding the second air-guiding channel 40f. It is primarily used to absorb liquid discharged from the airflow channel 10a (e.g., leaked aerosol matrix, condensate formed by cooling the aerosol, etc.). A drainage structure 40g disposed between the airflow channel 10a and the second air-guiding channel 40f directs the liquid toward the absorbing liquid 42, thereby preventing the liquid from leaking outside the aerosol generating device A through the second air-guiding channel 40f. In practice, the absorbing liquid 42 can be made of absorbent cotton or other suitable materials with strong liquid adsorption capabilities.
[0118] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For those skilled in the art of the present application, based on the concept of the present application, they can also make some simple deductions, modifications or substitutions.
