[0047] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0048] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0049] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0050] See also Figures 1 to 9 The embodiment of the present application provides an aerosol generating device, such as an electronic cigarette device, an electronic atomizer, etc.; the aerosol generating device includes an atomizing device A and other functional components that exist as needed; wherein the atomizing device A includes a shell assembly 10, an atomizing assembly 20, a valve assembly 30 and other functional components that exist as needed, which are described in detail below.

[0051] See also Figures 1 to 6 The shell assembly 10 can be understood as a collection of related components that constitute the overall outline of the atomization device A or the aerosol generating device; illustratively, the shell assembly 10 can be constructed by combining an outer shell, structural parts arranged inside the outer shell, etc.; with the help of the shell assembly 10, the user can carry, move, hold, operate and use the aerosol generating device.

[0052] A liquid storage chamber 10a and a receiving chamber 10b are formed inside the shell assembly 10, and the liquid storage chamber 10a and the receiving chamber 10b are arranged in communication with each other; wherein the receiving chamber 10b is mainly used to provide a placement space for the liquid storage device B so that the liquid storage device B can be accommodated and placed inside the atomization device A, and the liquid storage device B contains an aerosol matrix; and the liquid storage chamber 10a is mainly used to store the aerosol matrix injected from the liquid storage device B.

[0053] It should be noted that the liquid storage device B can have a larger liquid storage volume than the liquid storage chamber 10a, so that the aerosol matrix can be injected into the liquid storage chamber 10a multiple times through the liquid storage device B. For example, the volume of the liquid storage chamber 10a is 2 ml, and the volume of the liquid storage device B can be set to 10 ml or other parameters; in specific implementation, the liquid storage device B can be selected and set to a specific shape according to the contour shape of the accommodating chamber 10b. For example, the liquid storage device B can be a cylindrical bottle structure.

[0054] As for the aerosol matrix, it can be a liquid medium such as physiological saline, liquid medicine, liquid extract, and tobacco oil; illustratively, the components of a typical aerosol generating matrix are propylene glycol, glycerol, nicotine, and flavoring substances, etc. It can be understood that the aerosol matrix does not constitute a limitation on the atomization device A or the aerosol generating device of this embodiment.

[0055] See also Figures 2 to 5 The atomizing assembly 20 mainly plays the role of heating the aerosol matrix to generate an aerosol. The atomizing assembly 20 is arranged in the liquid storage chamber 10a and is connected to the outside of the housing assembly 10. It can be understood that the housing assembly 10 is internally formed with an air flow channel for air flow and aerosol to enter and exit. The air flow channel can generally include an air inlet channel, an atomizing channel and an air outlet channel that are connected in sequence (please refer to the embodiment of the embodiment of the present invention). Figure 2 and Figure 3 The atomizing assembly 20 constitutes an atomizing channel or is disposed in the atomizing channel. The atomizing assembly 20 is used to heat the aerosol in the liquid storage chamber 10a, so that the generated aerosol can be discharged from the air outlet channel along with the air flow for use.

[0056] During specific implementation, the atomization assembly 20 can be selected and set with reference to existing oil-core separation atomization structures, non-oil-core separation atomization structures, etc.

[0057] For example, the atomization component 20 can be a non-oil core separation atomization structure constructed by combining a liquid guide member, a heating member, etc. The liquid guide member can be made of a porous material, a fiber material, or other materials with capillary force; illustratively, the liquid guide member is a combination of one or more materials such as porous ceramics, cotton fibers, metal fibers, and non-woven fabrics. The liquid guide member is arranged in the liquid storage chamber 10a and is connected and arranged between the air inlet channel and the air outlet channel to form an atomization channel; the heating member can be a heating wire or a mesh heating member arranged on the liquid guide member. In the process of the liquid guide member attracting the aerosol matrix in the liquid storage chamber 10a into the atomization channel, the heating member can be used to heat the aerosol matrix and finally generate a usable aerosol.

[0058] See also Figures 2 to 9 The valve assembly 30 is arranged inside the shell assembly 10, for example, in the space area where the liquid storage chamber 10a and the accommodating chamber 10b are connected to each other; the valve assembly 30 mainly plays the role of sealing and opening the liquid storage chamber 10a at the connection between the liquid storage chamber 10a and the accommodating chamber 10b.

[0059] For example, the valve assembly 30 has an injection channel 30a, which is configured as follows: when the valve assembly 30 is pressed by the liquid storage device B, the injection channel 30a can be opened to connect the liquid storage device B and the liquid storage chamber 10a; when the liquid storage device B releases the pressure on the valve assembly 30, the injection channel 30a can be closed to seal the liquid storage chamber 10a.

[0060] Specifically, after the liquid storage chamber 10a is injected with the aerosol matrix or the liquid storage device B is not placed in the accommodating chamber 10b, the injection channel 30a is closed, so that the valve assembly 30 is used to seal the liquid storage chamber 10a, which can ensure that the aerosol matrix in the liquid storage chamber 10a is heated and atomized by the atomization assembly 20 to achieve normal use of the atomization device, and can also prevent the aerosol matrix in the liquid storage chamber 10a from leaking into the accommodating chamber 10b or flowing back into the liquid storage device B.

[0061] Specifically, in the process of injecting aerosol matrix into the liquid storage chamber 10a, the valve assembly 30 can be pressed by the liquid storage device B to trigger or prompt the injection channel 30a to open the liquid storage chamber 10a, thereby establishing a liquid path connection relationship between the liquid storage device B and the liquid storage chamber 10a with the help of the injection channel 30a, so that the aerosol matrix in the liquid storage device B can be smoothly injected into the liquid storage chamber 10a.

[0062] In one embodiment, see Figures 2 to 7 The valve assembly 30 includes a movable part 31, a fixed part 32 and an elastic part 33; wherein the fixed part 32 is fixed in the liquid storage chamber 10a, the movable part 31 is arranged at the connection between the liquid storage chamber 10a and the accommodating chamber 10b, the injection channel 30a runs through the movable part 31, and the fixed part 32 is arranged through the movable part 31 via the injection channel 30a; correspondingly, the elastic part 33 can adopt an elastic structural part with opposite two ends such as a spring, an elastic column, an elastic folding sheet, etc., one end of the elastic part 33 is connected to the fixed part 32 or the housing assembly 10 by abutting, fixing or other connection methods, and the other end of the elastic part 33 is abutted or fixed to the movable part 31.

[0063] Thus, the movable member 31 can move relative to the fixed member 32 toward the side of the accommodating chamber 10b to a position where it abuts against and covers the liquid injection port of the liquid storage device B under the elastic force provided by the elastic member 33, so that the fixed member 32 can close the liquid injection channel 30a from the end of the liquid injection channel 31 away from the liquid storage chamber 10a, thereby achieving a sealed closure of the liquid storage chamber 10a (see Figure 4 ).

[0064] On the contrary, when the movable member 31 is acted upon by an external force (e.g., the pressing force of the liquid storage device B), it can move toward the side of the liquid storage chamber 10a relative to the fixed member 32, so that the fixed member 32 opens the injection channel 30a, and connects the liquid storage device B with the liquid storage chamber 10a by means of the communication relationship established between the liquid storage chamber 10a and the liquid storage device B through the injection channel 30a, so as to inject the aerosol matrix into the liquid storage chamber 10a (see Figure 5 ).

[0065] In some embodiments, the elastic member 33 may be omitted, and the movable member 31 may be configured as a structure that can elastically expand and contract along the direction of the pressure applied by the liquid storage device B. By virtue of the structural feature of the movable member 31 itself being able to undergo elastic deformation, when the movable member 31 is subjected to the pressure of the liquid storage device B, the movable member 31 may be able to move toward the side of the liquid storage chamber 10a relative to the fixed member 32, thereby opening the injection channel 30a; conversely, the fixed member 32 may be cooperated to close the injection channel 30a.

[0066] In another embodiment, see Figure 8 and Fig. 9 The valve assembly 30 includes a sealing member 34 of an elastic material, and the sealing member 34 is fixedly arranged at the connection point between the liquid storage chamber 10a and the accommodating chamber 10b. The sealing member 34 can be arranged into a sleeve structure; the cross-sectional area of ​​the sleeve space of the sealing member 34 gradually decreases from the side of the sealing member 34 toward the liquid storage device B (or the accommodating chamber 10b) to the side of the sealing member 34 toward the liquid storage chamber 10a; thereby forming a tapered injection channel 30a inside the sealing member 34; it can be understood that at least the structural part of the sealing member 34 that surrounds the injection channel 30a is made of elastic material.

[0067] Thus, when the liquid storage device B moves toward the liquid storage chamber 10a to press against the sealing member 34 (for example, when the liquid injection port of the liquid storage device B gradually extends into the liquid injection channel 30a), the liquid injection channel 30a can be gradually opened, so that the liquid storage device B and the liquid storage chamber 10a are connected by the liquid injection channel 30a. When the liquid storage device B releases the pressure on the sealing member 34 (for example, when the liquid storage device B moves away from the liquid storage chamber 10a, so that the liquid injection port of the liquid storage device B gradually moves out from the sealing member 34 or the liquid injection channel 30a), the sealing member 34 can undergo elastic recovery deformation to shrink or close the liquid injection channel 30a, thereby closing the liquid storage chamber 10a.

[0068] In other embodiments, the valve assembly 30 may also adopt other valve structures, such as a one-way valve. With the one-way conduction function of the one-way valve, it can not only provide support for the injection of the aerosol matrix in the liquid storage device B into the liquid storage chamber 10a, but also prevent the aerosol matrix in the liquid storage chamber 10a from leaking or backflowing.

[0069] In one embodiment, see Figures 2 to 6 The housing assembly 10 includes a housing member 11 and a trigger member 12; wherein the liquid storage chamber 10a and the accommodating chamber 10b are both formed inside the housing member 11; the trigger member 12 is arranged at a side of the accommodating chamber 10b away from the liquid storage chamber 10a, facing the valve assembly 30.

[0070] For example, the liquid storage chamber 10a and the accommodating chamber 10b are arranged in communication along the up-down direction of the atomizing device, the valve assembly 30 is arranged at the top of the accommodating chamber 10b, and the trigger member 12 is arranged at the bottom of the accommodating chamber 10b facing the valve assembly 30; for another example, according to the overall structural construction of the atomizing device or the shell assembly 10, when the accommodating chamber 10b is arranged in communication with the upper side, left side, right side, etc. of the liquid storage chamber 10a, the spatial position of the trigger member 12 relative to the valve assembly 30 also needs to be adjusted accordingly.

[0071] The trigger member 12 can be a structural member movably mounted on the shell member 11, or it can be a deformable structure arranged at the portion of the shell member 11 corresponding to the liquid storage device B. By utilizing the arrangement relationship in which the trigger member 12 and the valve assembly 30 are spaced apart from each other, on the one hand, the liquid storage device B can be confined within the accommodating chamber 10b (specifically, in the area between the trigger member 12 and the valve assembly 30); on the other hand, with the aid of the trigger member 12, the liquid storage device B can be driven to move toward the side of the valve assembly 30, so as to trigger the valve assembly 30 through the liquid storage device B to connect the liquid storage chamber 10a and the liquid storage device B.

[0072] For example, by pressing the trigger member 12, the trigger member 12 moves relative to the shell member 11 toward the side of the liquid storage chamber 10a, or the trigger member 12 undergoes structural deformation toward the side of the liquid storage chamber 10a, thereby pressing and pushing the liquid storage device B to move toward the valve assembly 30, and then utilizing the abutment relationship between the liquid storage device B and the movable member 31 to prompt the movable member 31 to follow the liquid storage device B to move toward the side of the liquid storage chamber 10a, which is equivalent to allowing the fixed member 32 to open the injection channel 30a (at the same time, the elastic member 33 is compressed and stores elastic potential energy); when the force applied by the trigger member 12 to the liquid storage device B is released, the movable member 31 can drive the liquid storage device B (together with the trigger member 12) to move toward the side away from the liquid storage chamber 10a under the elastic force provided by the elastic member 33, thereby allowing the fixed member 32 to close the injection channel 30a.

[0073] For example, in an embodiment in which the valve assembly 30 adopts an existing one-way valve structure, the liquid storage device B can be clamped and positioned between the trigger member 12 and the valve assembly 30 with the help of the trigger member 12, so that the liquid storage device B maintains one-way communication with the liquid storage chamber 10a through the valve assembly 30, which is equivalent to triggering the valve assembly 30 to connect the liquid storage device B and the liquid storage chamber 10a; at this time, the aerosol matrix in the liquid storage device B can enter the liquid storage chamber 10a, while the aerosol matrix in the liquid storage chamber 10a cannot flow back into the liquid storage device B.

[0074] Firstly, by adding a accommodating chamber 10b which is relatively independent of the liquid storage chamber 10a inside the atomizing device, a corresponding placement space can be provided for the atomizing device A or the aerosol generating device carrying the liquid storage device B. Based on the aerosol matrix stored in the liquid storage device B, a series of problems in the related technology caused by the aerosol generating device being able to store only a fixed amount of aerosol matrix can be changed, and the aerosol matrix carrying amount of the aerosol generating device can be effectively increased, thereby creating favorable conditions for improving the endurance of the aerosol generating device and reducing the use cost.

[0075] Secondly, through the cooperation of the valve assembly 30 and the trigger member 12, the aerosol in the liquid storage device A can be easily and quickly injected into the liquid storage chamber 10a, reducing the cumbersomeness of the user's operation in the process of replenishing the aerosol matrix and improving the user experience.

[0076] Thirdly, by placing the liquid storage device B containing different aerosol matrices in the atomizing device A, aerosols with different flavors or functions can be injected into the liquid storage chamber 10a, thereby meeting the diverse usage needs of users.

[0077] The following takes the case where the accommodating chamber 10b is arranged at the lower side of the liquid storage chamber 10a and the trigger member 12 is arranged at the bottom of the accommodating chamber 10b or the shell assembly 10 as an example to illustrate the liquid injection operation of the aerosol generating device.

[0078] See also Figure 4 and Figure 5 When injecting the aerosol matrix into the liquid storage chamber 10a, the aerosol generating device can be turned in advance so that the trigger member 12 and the liquid storage device B are located above the valve assembly 30 and the liquid storage chamber 10a in the space environment; then the trigger member 12 is manipulated (for example, the trigger member 12 is pressed downward) to cause the liquid storage device B to move downward toward the valve assembly 30, thereby triggering the valve assembly 40 to connect the liquid storage device B and the liquid storage chamber 10a (for example, the liquid storage device B contacts the movable member 31 relative to the fixed member 32 to move toward the side of the liquid storage chamber 10a, so that the injection channel 30a is opened); thereby, the aerosol matrix in the liquid storage device B can flow into the liquid storage chamber 10a under the action of gravity, completing the injection operation of the aerosol matrix.

[0079] See also Figure 2 and Figure 4 After the aerosol matrix is ​​injected, the trigger member 12 is released, and the movable member 31 can move toward the side of the accommodating chamber 10b relative to the fixed member 32 under the action of the elastic member 33, thereby closing the injection channel 30a, achieving the effect of closing the liquid storage chamber 10a or cutting off the liquid storage chamber 10a and the liquid storage device B; then the user can operate the aerosol generating device normally; when the aerosol matrix in the liquid storage chamber 10a is exhausted, the injection operation can be performed again. When the aerosol matrix in the liquid storage device B is exhausted, the liquid storage device B can be removed from the accommodating chamber 10b and replaced with a new liquid storage device B.

[0080] It should be noted that the description of the liquid storage device B is introduced in the embodiments of the present application only to describe the structural structure, implementation principle and functional effect of the atomizing device A or the aerosol generating device in a clearer and more detailed manner, and does not mean that the liquid storage device B must be a component of the aerosol generating device. That is, in some embodiments, the liquid storage device B may be a component of the aerosol generating device; in other embodiments, the liquid storage device B may also be a consumable used in conjunction with the atomizing device A. In scenes such as factory delivery, transportation, and sales, the liquid storage device B and the atomizing device A can be packaged and stored separately; in scenes such as carrying and use, the user can place the liquid storage device B in the atomizing device A as needed.

[0081] In some embodiments, the housing component 10 may also adopt other suitable structural forms, such as omitting the trigger member 12; a window structure is provided at the position of the housing component 11 corresponding to the liquid storage device B (i.e., the position spaced opposite to the valve component 30), and after the liquid storage device B is placed in the accommodating chamber 10b, the end of the liquid storage device B away from its injection port can be exposed to the housing component 10 through the window structure, or at least partially protrude from the housing component 10 through the window structure; thus, by pushing the liquid storage device B toward the valve component 30, the valve component 40 can also be triggered to connect the liquid storage device B and the liquid storage chamber 10a, thereby completing the injection. In other embodiments, the trigger member 12 can also be provided at the liquid storage device B, which will not be described in detail here.

[0082] In one embodiment, see Figures 1 to 6 The shell body 11 includes a body portion 11a and an end cover portion 11b. The liquid storage chamber 10a and the accommodating chamber 10b are formed inside the body portion 11a, and the end cover portion 11b is arranged on a side of the accommodating chamber 10b away from the liquid storage chamber 10a, and the end cover portion 11b is detachably connected (for example, snap-fit ​​connection) or movably connected (for example, flip connection) to the body portion 11a.

[0083] Thus, the accommodating chamber 10b can be opened or closed with the help of the end cover portion 11b to achieve the placement or removal of the liquid storage device B; for example, the accommodating chamber 10a can be opened by removing the end cover portion 11b from the body portion 11a, so that the liquid storage device B can be conveniently and quickly placed in the accommodating chamber 10b, or the liquid storage device B can be removed from the accommodating chamber 10b; when the end cover portion 11b is installed on the body portion 11a, the accommodating chamber 10a can be closed, on the one hand, the liquid storage device B is restricted in the accommodating chamber 10b, so that the liquid storage device B establishes a structural connection relationship with the valve assembly 30, and on the other hand, the integrity of the outer contour structure of the atomization device or the aerosol generating device is maintained.

[0084] As for the trigger member 12, an assembly port 10d can be set at the position of the end cover portion 11b corresponding to the liquid storage device B (that is, the position opposite to the valve assembly 10), and the assembly port 10d is used as the installation position of the trigger member 12; for example, the trigger member 12 can be movably inserted and connected to the end cover portion 11b through the assembly port 10d; for another example, the trigger member 12 can also be set as an elastic structural member at the assembly port 10d.

[0085] In some embodiments where the trigger member 12 is omitted, the liquid storage device B can be exposed from the shell assembly 10 through the assembly port 10d or protrude from the end cover portion 11b through the assembly port 10d, so that the valve assembly 30 can be triggered by directly pushing the liquid storage device B to connect the liquid storage device B and the liquid storage chamber 10a.

[0086] In one embodiment, see Figures 4 to 7 The movable part 31 includes an inner core portion 31a and an outer cover portion 31b, and the inner core portion 31a and the outer cover portion 31b are roughly tubular structures; wherein, the tubular body space of the inner core portion 31a is equivalent to the injection channel 30a, that is, the injection channel 30a is set through the inner core portion 31a; the outer cover portion 31b is coaxially sleeved on the periphery of the inner core portion 31a; correspondingly, the elastic member 33 can be connected between the outer cover portion 31b and the fixed member 32 (or the shell assembly 10).

[0087] With the help of the outer cover portion 31b, a structural connection relationship can be established between the movable part 31 and the liquid storage device B, and under the elastic action of the elastic part 33, the inner core portion 31a can be sealed to cover the injection port of the liquid storage device B (for example, the bottle mouth of the liquid storage bottle); on the one hand, when the fixing part 32 opens the injection channel 30a, the internal space of the liquid storage device B can be connected with the liquid storage cavity 10a through the injection channel 30a; on the other hand, when the fixing part 32 closes the injection channel 30a, the injection port of the liquid storage device B can be closed with the help of the inner core portion 31a to prevent the aerosol matrix in the liquid storage device B from leaking into the accommodating cavity 10b.

[0088] In specific implementation, the inner core portion 31a and the outer cover portion 31b can adopt an integrated structure; the inner core portion 31a and the outer cover portion 31b can also adopt a split combined structure, for example, a first sealing member 31e such as a sealing ring is provided at the position where the inner core portion 31a and the outer cover portion 31b are plugged and connected to each other to eliminate the structural gap between the inner core portion 31a and the outer cover portion 31b, so as to prevent the aerosol matrix from leaking from between the inner core portion 31a and the outer cover portion 31b.

[0089] For some examples, see Figure 7 A second sealing member 31f is further provided between the outer cover portion 31b and the fixed member 32 (or the shell assembly 10). The second sealing member 31f can play a structural sealing role between the movable member 31 and the fixed member 32 (or the shell assembly 10), thereby achieving the effect of preventing the leakage of the aerosol matrix.

[0090] In one embodiment, see Figure 7 Combined with Figure 4 and Figure 5 A fixed gap 31c is formed between the inner core 31a and the outer cover 31b. Specifically, on the side of the movable member 31 close to the accommodating chamber 10b, there is a certain structural gap between the outer circumference of the inner core 31a and the inner circumference of the outer cover 31b, which is the fixed gap 31c. When the liquid storage device B is placed in the accommodating chamber 10b, the fixed gap 31c can be used to accommodate the side wall of the liquid injection port of the liquid storage device B, and at least part of the inner core 31a extends into the interior of the liquid storage device B through the liquid injection port of the liquid storage device B, and the outer cover 31b is equivalent to being placed outside the liquid storage device B at the liquid injection port of the liquid storage device B, so as to ensure that the end face of the inner core 31a in the axial direction of the liquid injection channel 30a can be against the end face of the liquid injection port of the liquid storage device B; thereby, the liquid injection port of the liquid storage device B can be sealed.

[0091] For specific implementation, please refer to Figure 6 and Figure 7 , a plurality of fixing structures 31d may be provided on the outer cover portion 31b, and the fixing structures 31d may be a hook structure, an elastic arm structure, etc. extending toward one side of the accommodating chamber 10b, and the plurality of fixing structures 31d are arranged at intervals around the axis of the injection channel 30a. With the help of the fixing structures 31d, the liquid storage device B can be clamped and fixed at the periphery of the injection port of the liquid storage device B, which can not only stably accommodate the side wall of the injection port of the liquid storage device B in the fixed gap 10c, ensuring that the inner core portion 31a abuts against and covers the injection port of the liquid storage device B; but also can conveniently and quickly combine the structure of the liquid storage device B with the valve assembly 30, and remove and replace the liquid storage device B.

[0092] For some examples, see Figure 7A third sealing member 31g may be provided on the periphery of the inner core portion 31a. With the aid of the third sealing member 31g, the structural gap between the inner core portion 31a and the side wall of the liquid injection port of the liquid storage device B may be eliminated, thereby ensuring that the liquid storage device B and the liquid injection channel 30a are effectively sealed and connected, while preventing leakage of the aerosol matrix in the liquid storage device B.

[0093] In other embodiments, the fixed structure 31d may also be omitted. By selecting and setting the structural forms or dimensional parameters such as the fixed gap 31c, the outer cover portion 31b, and the inner core portion 31a, the liquid storage device B establishes a structural connection relationship with the outer cover portion 31b or the movable part 31 by means of interference fit, or a threaded structure is provided on the inner circumferential surface of the outer cover portion 31b located in the fixed gap 31c, and the liquid storage device B is inserted and assembled in the outer cover portion 31b by means of a threaded connection.

[0094] Of course, the inner core portion 31a may not extend into the interior of the liquid storage device B, and only the connection relationship between the outer cover portion 31b (specifically the fixing structure 31d) and the liquid storage device B is utilized to make the inner core portion 31a abut against and seal the liquid injection port of the liquid storage device B.

[0095] In one embodiment, see Figures 4 to 7 The fixing member 32 includes a positioning portion 32a and a sealing portion 32b; wherein the positioning portion 32a is arranged to penetrate the movable member 31 (for example, the inner core portion 31a), and the end of the positioning portion 32a away from the accommodating chamber 10b is fixed in the liquid storage chamber 10a, while the sealing portion 32b is arranged at the end of the positioning portion 32a close to the accommodating chamber 10b (that is, the side of the movable member 31 facing the accommodating chamber 10b); in specific implementation, the contour size of the sealing portion 32b can be set to be larger than the port size of the injection channel 30a, so that when the movable member 31 moves toward the side of the accommodating chamber 10b under the action of the elastic member 33 to the position where the sealing portion 32b abuts against each other, the sealing portion 32b can close the injection channel 30a; conversely, when the movable member 31 is separated from the sealing portion 32b, the injection channel 30a can be opened.

[0096] In some embodiments, an annular flange structure may be provided on the positioning portion 32a, and a sealing portion 32b may be formed by coating the annular flange structure with a sealing material (e.g., a silicone sleeve). In other embodiments, the end of the positioning portion 32a at the side of the sealing portion 32b facing the accommodating cavity 10b may be provided as a cone-shaped structure, so that when the liquid storage device B provided with a sealing film is placed in the accommodating cavity 10b, the sealing film of the liquid storage device B may be pierced by the positioning portion 32a.

[0097] In one embodiment, see Figures 2 to 5The atomizing device A also includes a control component 40, which is electrically connected to the atomizing component 20 and is mainly used to control the atomizing component 20 to start and stop heating, or adjust the heating mode of the atomizing component 20, etc.; in specific implementation, according to the functional configuration of the atomizing device A or the aerosol generating device, the control component 40 can be constructed by a combination of a control board, a battery cell, a pneumatic switch, etc.

[0098] For the housing assembly 10, see Figures 1 to 4 An assembly cavity 10e is also formed inside the shell component 10 (specifically, the body portion 11a), and the control component 40 is disposed in the assembly cavity 10e; the assembly cavity 10e and the accommodating cavity 10b are arranged side by side on the same side of the liquid storage cavity 10a (for example, the lower side of the liquid storage cavity 10a), and at the same time, the shell component 10 is also provided with a nozzle structure 10f connected to the atomization component 20, and the nozzle structure 10f can be understood as an air outlet channel of the atomization device A or the aerosol generating device, and the nozzle structure 10f is located on the side of the liquid storage cavity 10a away from the assembly cavity 10e (for example, the upper side of the liquid storage cavity 10a).

[0099] By partitioning the internal structural space of the shell assembly 10, the structure of the atomizer device A or the aerosol generating device can be made more compact. At the same time, the control component 40 and the liquid storage device B can be arranged on the same side of the liquid storage chamber 10a (for example, the lower half of the atomizer device A) by using the assembly chamber 10e and the accommodating chamber 10b, respectively. An air flow channel can be set in the upper half where the liquid storage chamber 10a and the atomizer assembly 20 are located, thereby shortening the length of the air flow channel and creating favorable conditions for rapid generation and discharge of rapid aerosol and reduced inhalation resistance.

[0100] In other embodiments, the control component 40 may be a functional device relatively independent of the atomization device A, which may also be understood as omitting the assembly chamber 10e; the control component 40 may be detachably or non-detachably mounted on the atomization device A in such a manner that it can be arranged side by side with the liquid storage device B on the same side of the liquid storage chamber 10a.

[0101] See also Fig.10 and Fig.11 Combined with Figure 3 The embodiment of the present application also provides an aerosol generating device, which is mainly different from the aerosol generating device in the aforementioned embodiment in that: the valve assembly 30 is arranged in the liquid storage device B, and through the pressing and fitting relationship between the liquid storage device B and the atomizing device A, the valve assembly 30 can be opened to connect the liquid storage chamber 10a and the liquid storage device B; the specific description is as follows.

[0102] See also Fig.10 and Fig.11The liquid storage device B includes a liquid storage container 50 and a valve assembly 30; the valve assembly 30 is arranged at the liquid injection port of the liquid storage container 50 to seal and close the liquid storage container 50; the valve assembly 30 may include a sealing member 34 of elastic material, and the sealing member 34 may be arranged to be a sleeve-type structure that at least partially extends into the liquid storage container 50 through the liquid injection port of the liquid storage container 50, and the cross-sectional area of ​​the sleeve space of the sealing member 34 gradually increases from one end of the sealing member 34 toward the inside of the liquid storage container 50 toward the other end of the sealing member 34 toward the outside of the liquid storage container 50, thereby configuring the sleeve space of the sealing member 34 into an injection channel 30a that is approximately conical.

[0103] Accordingly, with respect to the atomizing device A, see Fig.11 Combined with Figure 3 A liquid injection piece 13 is provided at the connection point between the liquid storage chamber 10a and the accommodating chamber 10b; the liquid injection piece 13 may be a tubular structure at least partially protruding into the accommodating chamber 10b, or may be other components with a through-hole structure or a hollow structure.

[0104] When the liquid storage device B is placed in the accommodating chamber 10b, the injection piece 13 and the valve assembly 30 (specifically, the sealing piece 34) are opposite to each other. When a force is applied to cause the liquid storage device B to move toward the side of the liquid storage chamber 10a, the injection piece 13 can be extended into the injection channel 30a, thereby gradually expanding the injection channel 30a by pressing the sealing piece 34, thereby opening the injection channel 30a and connecting the liquid storage chamber 10a and the liquid storage container 50.

[0105] On the contrary, when the liquid storage device B moves toward the side away from the injection piece 13, the injection piece 13 and the sealing piece 34 can be gradually separated, thereby releasing the pressing force exerted by the injection piece 13 on the sealing piece 34, so that the injection channel 30a gradually shrinks or closes due to the elastic recovery deformation of the sealing piece 34, thereby closing the liquid storage container 50 or isolating the liquid storage cavity 10a and the liquid storage container 50.

[0106] In some embodiments, the valve assembly 30 may also be structurally arranged with reference to the valve assembly in the aerosol generating device of the aforementioned embodiment; or the liquid injection member 13 may be omitted, and the valve assembly 30 may be prompted to open or close the liquid injection channel 30a by utilizing the structure of the connection between the liquid storage chamber 10a and the accommodating chamber 10b and the pressure-matching relationship between the liquid storage device B (specifically, the liquid storage container 50). All these will not be elaborated here.

[0107] As for other functional components of the aerosol generating device of this embodiment and their mutual coordination relationship, they can be set with reference to the aerosol generating device of the aforementioned embodiment; for example, the shell assembly 10 can be constructed by combining a shell member 11 and a trigger member 12. With the help of the trigger member 12, the liquid storage device B can be packaged and placed in the accommodating cavity 10b, and the liquid storage device B can also be driven to move toward the side of the liquid storage cavity 10a, so that the injection member 13 presses against the valve assembly 30 arranged at the injection port of the liquid storage container 50, thereby connecting the liquid storage cavity 10a and the liquid storage container 50.

[0108] It should be noted that Figure 2 and Figure 3 The bold dashed line with an arrow in the figure represents the approximate path or direction of the airflow along the airflow channel. Figure 5 The bold solid line with an arrow in the middle represents the force direction or movement direction of the trigger member 12. Figure 5 The dashed line with an arrow in the middle represents the approximate path or direction of the aerosol matrix flowing from the liquid storage device B to the liquid storage chamber 10a. Fig. 9 and Fig.11 The bold solid line with an arrow in the middle represents the approximate path or direction of the aerosol matrix flowing from the liquid storage device B through the injection channel 30a to the liquid storage chamber 10. Fig. 9 and Fig.11 The bold dashed line with an arrow in the middle represents the moving direction of the liquid storage device B.

[0109] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
