Description

Technical Field

[0001] The present invention relates to the technical field of electronic atomization, and in particular to an aerosol generating device. Background Art

[0002] With the increasing popularity of aerosol-generating devices, they are now ubiquitous in everyday life and in ordinary households. Aerosol-generating devices typically consist of a housing, an atomizer assembly, and a power supply assembly. The power supply assembly, as the energy supply unit, has a significant impact on the safety of the entire aerosol-generating device. These power supplies typically utilize rechargeable lithium batteries as energy storage components.

[0003] The energy storage component includes an electrode and a main body. The electrode is arranged on the main body, one end of which is connected to the electrode inside the main body, and the other end is connected to the power supply circuit of the aerosol generating device. The covering unit of the main body will form a seam at the electrode. When the energy storage component is in abnormal charging or the temperature is too high during use, thermal runaway will occur. The energy storage component will release a large amount of high-temperature and high-pressure gas in the aerosol generating device, and then pressure relief will occur. Since there is a seam between the electrode and the covering unit, the high-temperature and high-pressure gas will be released from the seam into the interior of the aerosol generating device. The high-temperature and high-pressure gas accumulates in the outer shell of the aerosol generating device, which will cause the gas pressure in the outer shell to be too high, posing a risk of explosion. On the other hand, since the aerosol generating device has a mouth end, which is connected to the outside world, the large amount of high-temperature and high-pressure gas generated is easily ejected from the mouth end, causing the high-temperature and high-pressure gas to be directed towards the user, posing a pressure relief safety problem.

[0004] Therefore, how to reduce the impact force of the pressure release at the base of the aerosol generating device, reduce the risk of concentrated release of high-temperature and high-pressure gas directly in the axial direction, and improve the safety of the aerosol generating device has become a technical problem that needs to be solved urgently. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem of how to reduce the impact force of the pressure release of the base of the aerosol generating device, reduce the risk of concentrated release of high-temperature and high-pressure gas directly in the axial direction, and improve the safety of the aerosol generating device.

[0006] In a first aspect, the present invention provides an aerosol generating device, comprising: a housing having side walls extending along a first direction; a base located at the bottom end of the housing; an energy storage component located within the housing and comprising an electrode, the electrode being located at one end of the energy storage component facing the base along the axial direction of the aerosol generating device; wherein a central axis of the energy storage component forms an angle less than 90 degrees with the first direction.

[0007] Using the above technical solution, the electrode is located at one end of the energy storage component, along the axial direction of the aerosol generating device, facing the base. When the energy storage component depressurizes, the high-temperature, high-pressure gas generated by the depressurization is released from the sealed portion at the end where the electrode is located. The sidewalls of the housing extend along a first direction, and the central axis of the energy storage component forms an angle of less than 90 degrees with the first direction. In this placement, the central axis of the energy storage component forms an angle of less than 90 degrees with the first direction, and the impact force generated by the depressurization can be decomposed into two components: a component perpendicular to the base, which impacts the base; and a component perpendicular to the sidewalls of the housing, which impacts the sidewalls. This will result in the component force perpendicular to the base being smaller than the total impact force generated by the pressure relief, which means that the impact force acting on the base is weakened and dispersed, and it is no longer entirely impacted on the base along the axial direction. Part of the impact force can be released on the side wall of the shell in the form of a component force perpendicular to the side wall, thereby reducing the impact force concentrated in the direction of the base, reducing the risk of high-temperature and high-pressure gas generated by the pressure relief being directly released in the axial direction, reducing the risk of explosion of the aerosol generating device due to excessive pressure, and improving the safety of the aerosol generating device.

[0027] It should be noted that in this specification, similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0028] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0029] Figure 1 The aerosol generating device 100 comprises a housing 1 having a side wall 11 extending in a first direction. Figure 1Direction A in the aerosol generating device 100. One end of the outer shell 1 along the axial direction of the aerosol generating device 100 is the mouth end 12, and the other end is the bottom end 13. The aerosol generating device 100 also includes a base, which is located at the bottom end of the outer shell 1. The electrode 31 is located at the end of the energy storage component 3 along the axial direction of the aerosol generating device 100 away from the base 21, and the central axis L1 of the energy storage component is parallel to the first direction. When the energy storage component 3 has an internal fault (such as a short circuit or overcharging), pressure relief will occur, and the pressure relief will produce a large amount of high-temperature and high-pressure gas. In this case, when the energy storage component 3 is depressurized, the high-temperature and high-pressure gas generated by the pressure relief will rush out from the seal of the electrode of the energy storage component, and the high-temperature and high-pressure gas will rush out along the axial direction of the aerosol generating device 100 toward the end away from the base 21, that is, it will generate an impact force toward the mouth end, which may easily cause damage to the user.

[0030] Figure 2 The aerosol generating device 100 comprises a housing 1 having a side wall 11 extending in a first direction. Figure 2 The aerosol generating device 100 also includes a base located at the bottom end of the housing 1. The electrode 31 is located at one end of the energy storage component 3, along the axial direction of the aerosol generating device 100, that faces the base 21. In this embodiment, the central axis L1 of the energy storage component is parallel to the first direction. In this case, the impact force generated by the pressure relief will entirely impact the base 21, posing a risk of direct, concentrated axial release of high-temperature, high-pressure gas, posing a safety concern.

[0031] like Figure 3 and Figure 4 As shown, in a first aspect, the present invention provides an aerosol generating device 100, comprising: a housing 1 having a side wall 11, the side wall 11 extending along a first direction. Figure 3 and Figure 4 The base 21 is located at the bottom end 13 of the housing 1. One end of the housing 1 along the axial direction of the aerosol generating device 100 is the mouth end 12, and the other end is the bottom end 13. The axial direction of the aerosol generating device 100 is Figure 3 and Figure 4 The energy storage component 3 is located in the housing 1. The energy storage component 3 includes an electrode 31, which is located in the axial direction of the aerosol generating device 100 ( Figure 3 and Figure 4 The central axis L1 of the energy storage component is aligned with the first direction ( Figure 3 and Figure 4 The energy storage component 3 is placed in such a way that the central axis L1 of the energy storage component is aligned with the first direction ( Figure 3 and Figure 4The first direction is the axial direction of the aerosol generating device. The energy storage component 3 is, for example, a battery element. Specifically, the electrode 31 can be a tab, a lead, or a contact.

[0032] If the central axis L1 of the energy storage component is parallel to or coincides with the extension direction of the side wall 11 of the housing 1, the impact force generated by the pressure relief will all impact the base 21, the impact force is large, and the risk of the high-temperature and high-pressure gas generated by the pressure relief being directly released in a concentrated manner along the axial direction is high. If the central axis L1 of the energy storage component is perpendicular to the extension direction of the side wall of the housing 1, the impact force generated by the pressure relief will all impact the side wall 11 of the housing 1, and there is a risk of the side wall 11 rupturing. In addition, if the central axis L1 of the energy storage component is perpendicular to the extension direction of the side wall of the housing 1, it occupies a large space perpendicular to the axial direction of the aerosol generating device 100, which is not convenient for the user to hold.

[0033] In the above embodiment, the electrode 31 is located at the energy storage component 3 along the axial direction of the aerosol generating device 100 ( Figure 3 and Figure 4 When the energy storage component 3 releases pressure, the resulting high-temperature, high-pressure gas is released from the sealed portion of the end where the electrode 31 of the energy storage component 3 is located. The sidewall 11 of the housing 1 extends along a first direction, and the central axis L1 of the energy storage component forms an angle of less than 90 degrees with the first direction. In this placement, the central axis L1 of the energy storage component forms an angle of less than 90 degrees with the first direction. The impact force F generated by the pressure release can be decomposed into two components: a first component F1 perpendicular to the base 21, which impacts the base 21; and a second component F2 perpendicular to the sidewall 11 of the housing 1, which impacts the sidewall 11. This will result in the first component force F1 perpendicular to the base 21 being smaller than the total impact force F generated by the pressure relief, which means that the impact force acting on the base 21 is weakened and dispersed, and no longer impacts the base 21 entirely in the axial direction. Part of the impact force can be released on the side wall of the shell in the form of a component force perpendicular to the side wall. The side wall 11 of the shell 1 bears part of the pressure relief impact force, thereby reducing the impact force concentrated in the direction of the base, reducing the risk of high-temperature and high-pressure gas generated by the pressure relief being directly released in the axial direction, reducing the risk of the aerosol generating device 100 exploding due to excessive pressure, and improving the safety of the aerosol generating device 100.

[0034] On the one hand, the electrode 31 is arranged on the energy storage component 3 along the axial direction of the aerosol generating device 100 ( Figure 3 and Figure 4 The center axis L1 of the energy storage component is aligned with the first direction (the X direction) toward one end of the base 21, so that when the energy storage component is depressurized, the high-temperature and high-pressure gas generated by the depressurization is prevented from being discharged from the mouth end, thereby reducing the risk of causing damage to the user. Figure 3 and Figure 4 A direction in the middle (in the middle) forms an angle α less than 90 degrees, so that the side wall 11 and the base 21 jointly bear the impact force generated by the pressure relief, reducing the risk of the aerosol generating device 100 exploding due to excessive pressure.

[0035] In some embodiments, at least one electrode 31 of the energy storage component 3 is located in the axial direction of the aerosol generating device 100 ( Figure 3 and Figure 4 The positive electrode 31 of the energy storage component 3 is located at the axial direction of the aerosol generating device 100 ( Figure 3 and Figure 4 Furthermore, the two electrodes 31 of the energy storage component 3 are both located in the axial direction of the aerosol generating device 100 ( Figure 3 and Figure 4 The X direction in FIG. 2 is toward one end of the base 21.

[0036] According to another specific embodiment of the present invention, continue to refer to Figure 3 The base 21 is provided with a pressure relief port 211, which is communicated with one end of the energy storage component 3 where the electrode 31 is located. Further, the pressure relief port 211 is communicated with the space at one end of the energy storage component 3 where the electrode 31 is located.

[0037] In the above embodiments, the pressure relief port 211 located on the base 21 allows the gas in the energy storage component 3 to be quickly discharged from the pressure relief port 211. The pressure relief port 211 is connected to one end of the energy storage component 3 where the electrode 31 is located, providing a direct and unobstructed outlet for the gas generated at the seal of the electrode 31, effectively alleviating the accumulation of gas pressure generated by the energy storage component 3 inside the aerosol generating device 100, and preventing the internal pressure of the aerosol generating device 100 from continuously and sharply increasing. The pressure relief port 211 provided on the base 21 enables the gas in the aerosol generating device 100 to be discharged in a timely manner. When the energy storage component 3 abnormally releases pressure, the high-temperature and high-pressure gas generated inside the energy storage component 3 can be quickly and smoothly released to the outside of the aerosol generating device 100 through the pressure relief port 211, avoiding excessive accumulation of gas in the aerosol generating device 100, and preventing the pressure from reaching a dangerous level that causes physical rupture or explosion of the aerosol generating device 100, thereby providing safety for the aerosol generating device 100.

[0038] According to another specific embodiment of the present invention, continue to refer to Figure 3 The housing 1 has a redundant space 14 therein, and the redundant space 14 is axially located between the electrode 31 and the base 21 .

[0039] In each of the above-described embodiments, a redundant space 14 is reserved between the electrode 31 end of the energy storage component 3 and the base 21 to manage and buffer the high-temperature, high-pressure gas generated by pressure relief, thereby improving safety. When the energy storage component 3 experiences an abnormality and pressure relief, the pressure within the component 3 rises sharply, and gas is released through the sealed portion of the electrode 31. This instantaneously generated large amount of high-temperature, high-pressure gas requires space to diffuse and accommodate. Without the redundant space 14 axially disposed between the electrode 31 and the base 21, the gas pressure would be too high to be fully discharged, and the pressure would accumulate in a very small space. This creates a risk of excessive internal pressure within the aerosol generating device 100, causing physical rupture or explosion of the aerosol generating device 100. With the redundant space 14, the gas generated by pressure relief will first enter this space, acting as a buffer and containment mechanism, preventing the gas from instantly escaping from the pressure relief port 211 on the base 21 and causing a significant impact. Once the gas generated by pressure relief enters the redundant space 14, it expands and diffuses within this relatively large space, causing its pressure and temperature to decrease. This greatly reduces the initial pressure peak and impact force acting on the pressure relief port 211 on the base 21 of the aerosol generating device 100. The buffering effect of the redundant space 14 can also prolong the rush-out time of the gas, so that the gas has more time to be discharged through the pressure relief port, rather than being ejected instantly. The existence of the redundant space 14 also provides a certain directionality for the flow of gas. After entering the redundant space 14, the gas can flow more evenly in the direction of the base 21, rather than forming a concentrated impact flow. This helps to exhaust more effectively and reduce local high pressure or poor pressure relief caused by excessive concentration of gas flow. Due to the existence of the redundant space 14, even if the exhaust rate of the pressure relief port 211 temporarily cannot keep up with the gas generation rate of the energy storage component 3, the existence of the redundant space 14 can absorb part of the pressure increase and prevent the pressure inside the entire shell 1 from rising too high to a level that may cause the shell 1 to rupture and explode.

[0040] In some embodiments, the base 21 blocks the bottom end 13 of the housing 1 to prevent components inside the housing 1 from shifting and falling out of the housing 1 .

[0041] According to another specific embodiment of the present invention, continue to refer to Figure 3 The pressure relief port 211 is a charging port. Furthermore, the pressure relief port 211 is a Type-C charging port. The aerosol generating device 100 further includes a charging management module 4 , which includes a circuit board 41 axially located between the electrode 31 and the Type-C charging port. The circuit board 41 is connected to the Type-C charging port and to the electrode 31 .

[0042] In the above embodiment, the charging port located in the redundant space 14 can block the gas discharged from the electrode 31 in the energy storage component 3, so that the gas hitting the charging port is rebounded to the side wall 11 of the shell 1, thereby dispersing part of the impact force impacting the base 21.

[0043] In the above embodiments, the pressure relief port 211 serves as both the charging connection port and the exhaust port of the aerosol generating device 100. This allows the charging connection port and the pressure relief port 211 to be combined into one, achieving functional integration and space optimization. The TYPE-C charging port itself has a through-hole structure with metal contacts inside and a plastic or metal coating on the outside. However, there is usually a channel between the contacts and between the contacts and the housing 1 or the base 21. This structure is designed to serve as a channel for the discharge of pressure relief gas. When the pressure inside the housing 1 is too high, the gas inside the housing 1 can be discharged to the outside of the housing 1 through this TYPE-C charging port. Through this design, the pressure relief port 211 no longer needs to be a separate, additional exhaust structure. The TYPE-C charging port, which must exist as an interface structure, is directly used to achieve the pressure relief function, thereby achieving the integration of pressure relief and charging functions. Since the pressure relief function has been integrated into the TYPE-C charging port, there is no need to additionally design, manufacture, and install an independent exhaust structure, which directly saves the physical space occupied by some components.

[0044] In addition, the charging management module 4 includes a circuit board 41, which is located axially between the electrode 31 and the Type-C charging port of the aerosol generating device 100, shortening the transmission path of current and electrical signals. The compact arrangement of the electrode 31, circuit board 41, and integrated Type-C charging port of the energy storage component 3 along the axial direction further compacts the overall structure of the aerosol generating device 100, optimizes space, and further miniaturizes the aerosol generating device 100.

[0045] According to a specific embodiment of the present invention, Figure 4 , the angle α is less than 90 degrees, specifically, 0<α<90 degrees. For example, 0<α<60 degrees. For example, 0.5<α<45 degrees. For example, 0.5<α<30 degrees. More specifically, the angle α ranges from 0.5 degrees to 25 degrees. Preferably, the angle α ranges from 0.5 degrees to 5 degrees. That is, the central axis L1 of the energy storage component is aligned with the first direction ( Figure 3 and Figure 4 The angle α (direction A in the figure) ranges from 0.5 to 5 degrees. The first direction is the extension direction of the sidewall 11 of the housing 1. Experiments have shown that when the angle α ranges from 0.5 to 5 degrees, the ratio of the pressure relief impact force borne by the base 21 and the sidewall 11 is optimal, achieving the optimal balance between safety and miniaturization.

[0046] In the above embodiments, the central axis L1 of the energy storage component is aligned with the first direction ( Figure 3 and Figure 4 The range of the angle α (direction A in the figure) is 0.5 degrees to 5 degrees, and the energy storage component 3 remains inclined relative to the extension direction of the side wall 11 of the shell 1. The impact force F generated by the pressure relief can be decomposed into two components: a first component F1 perpendicular to the base 21, and the first component F1 will impact the base 21; a second component F2 perpendicular to the side wall 11 of the shell 1, and the second component F2 will impact the side wall 11. The larger the angle α, the larger the second component F2, and the smaller the first component F1. Within this range of angle α, while ensuring a better dispersion effect of the impact force F, the space of the shell along the first direction can be maximized to avoid excessive occupation of the space perpendicular to the side wall, making it easier for users to hold the aerosol generating device. If the space perpendicular to the axis of the aerosol generating device is too large, it will be inconvenient for users to hold it, and the user experience will be poor. The angle α ranges from 0.5 to 5 degrees, achieving a balance between pressure relief safety and device miniaturization. This avoids both the ineffective dispersion of the impact force F caused by an excessively small angle α and the excessive space occupied by the housing 1 due to an excessively large angle α. If the angle between the central axis L1 of the energy storage component and the extension direction of the sidewall 11 of the housing 1 is greater than 5 degrees, the energy storage component 3 will occupy a large amount of space perpendicular to the axial direction of the aerosol generating device 100, hindering the miniaturization of the aerosol generating device 100. By adjusting the angle α to 0.5 to 5 degrees, the ratio of the force components acting on the base 21 and the sidewall 11 can be precisely adjusted, optimizing the release path of the pressure relief gas and achieving an optimal balance between safety and miniaturization.

[0047] According to another specific embodiment of the present invention, the center of the energy storage component is located on the central axis L2 of the aerosol generating device.

[0048] In each of the above embodiments, the center O of the energy storage component is located on the central axis L2 of the aerosol generating device. This allows the energy storage component 3 to be relatively centered relative to the aerosol generating device 100 and not deviate from the side of the aerosol generating device 100 located on the central axis L2 of the aerosol generating device. This reduces the volume of the aerosol generating device 100. The aerosol generating device 100 is symmetrical along its central axis L2, and the energy storage component is not biased toward one side in a direction perpendicular to the central axis L2 of the aerosol generating device. If the center O of the energy storage component is not located on the central axis L2 of the aerosol generating device, but rather biased toward one side, then in order to accommodate this biased energy storage component 3, the housing 1 would need to provide additional space on the opposite side of the biased side, making the aerosol generating device 100 symmetrical along its central axis L2. This would result in an increase in the size of the aerosol generating device 100 perpendicular to the axial direction. By placing the center O of the energy storage component on the central axis L2 of the aerosol generating device, the symmetrical space within the aerosol generating device 100 can be maximized. The energy storage component 3 does not occupy excessive space on either side, making the internal layout of the aerosol generating device more compact. By avoiding the additional space required due to off-center placement, the effective volume occupied by the energy storage component (the volume accommodating the energy storage component 3 and the volume remaining due to the axial symmetry of the aerosol generating device 100) is reduced. This helps to reduce the overall external dimensions of the aerosol generating device 100, making the aerosol generating device 100 more compact and miniaturized.

[0049] In some embodiments, the center of the energy storage component is located on the central axis L2 of the aerosol-generating device, or on a line parallel to the central axis of the aerosol-generating device 100 .

[0050] According to another embodiment of the present invention, the aerosol generating device 100 further comprises a holding portion 5 located in the housing 1, the holding portion 5 clamping the energy storage component 3 so that the central axis L1 of the energy storage component is aligned with the first direction ( Figure 3 and Figure 4 The retaining portion 5 forms an angle α less than 90 degrees (in the direction A), and the retaining portion 5 clamps the energy storage component 3 to form a clamping surface 54. The extending direction of the clamping surface 54 is the same as the extending direction of the side surface of the energy storage component 3. In other words, the retaining portion 5 clamps the side surface of the energy storage component 3 to form the clamping surface 54.

[0051] In the above embodiments, the retaining portion 5 clamps the energy storage component 3 so that the central axis L1 of the energy storage component maintains an angle of less than 90 degrees with the first direction, and the central axis of the energy storage component 3 remains inclined relative to the extension direction of the side wall 11 of the housing 1. By designing the retaining portion 5 to clamp the energy storage component 3, the retaining portion 5 can forcibly fix the energy storage component 3 in a specific inclined placement orientation. In such a placement orientation, the central axis L1 of the energy storage component is at an angle of less than 90 degrees with the first direction ( Figure 3 and Figure 4 Without the retaining portion 5, the energy storage component 3 may be parallel or perpendicular to the extension direction of the side wall 11 of the housing 1 due to gravity or assembly errors. In addition, the retaining portion 5 clamps the energy storage component to form a clamping surface 54. The extension direction of the clamping surface 54 is the same as the extension direction of the side of the energy storage component 3, and the energy storage component 3 is more stably fixed in the housing 1. Through physical contact and constraint, the retaining portion 5 continuously and stably maintains the central axis L1 of the energy storage component at an angle less than 90 degrees with the first direction. Even if it is subjected to slight vibration or impact during use, the central axis L1 of the energy storage component can remain stable at an angle less than 90 degrees with the first direction. The extension direction of the clamping surface 54 is consistent with the extension direction of the energy storage component 3. The close fit reduces the possibility of displacement of the energy storage component under the action of the clamping force and reduces the possibility of the energy storage component 3 sliding or rotating within the retaining portion 5.

[0052] According to another specific embodiment of the present invention, continue to refer to Figure 3 The holding portion 5 includes: a first limiting portion 51; a second limiting portion 52, which clamps the energy storage component 3 together with the first limiting portion 51. The holding portion 5 also includes a bottom 53, which is axially ( Figure 3 and Figure 4 The bottom portion 53 is detachably connected to the first limiting portion 51 and is integrally formed with the second limiting portion 52. The first limiting portion 51, the second limiting portion 52 and the bottom portion 53 together accommodate the energy storage component 3. The first limiting portion 51 and the second limiting portion 52 are arranged along the second direction ( Figure 3 The Y direction in the Figure 3 The Y direction in the Figure 3 and Figure 4 The first limiting portion 51 and the second limiting portion 52 are arranged along the third direction ( Figure 3 The cross-sectional area of ​​the first limiting portion 51 in the third direction gradually increases along the third direction, and the cross-sectional area of ​​the second limiting portion 52 in the third direction gradually decreases along the third direction. The third direction is the direction from the mouth end 12 of the shell 1 to the bottom end 13 of the shell 1 along the axial direction, and the mouth end 12 of the shell 1 is the end opposite to the bottom end 13 along the axial direction.

[0053] In the above embodiment, the retaining portion 5 includes a first limiting portion 51, a second limiting portion 52 and a bottom portion 53, and the first limiting portion 51, the second limiting portion 52 and the bottom portion 53 jointly accommodate the energy storage component 3. The opposite end of the bottom along the third direction is an opening for accommodating the energy storage component 3. The bottom portion 53 is detachably connected to the first limiting portion 51, and the bottom portion 53 and the second limiting portion 52 are integrally formed. The cross-sectional area of ​​the first limiting portion 51 in the third direction gradually increases along the third direction, and the cross-sectional area of ​​the second limiting portion 52 in the third direction gradually decreases along the third direction. The first limiting portion 51 and the second limiting portion 52 are arranged along the second direction ( Figure 3 The first limiting portion 51 and the second limiting portion 52 are arranged opposite to each other in the Y direction in the third direction, and the energy storage component 3 is clamped together, and the bottom 53 forms a closed end. The first limiting portion 51, the second limiting portion 52 and the bottom 53 together constitute a accommodating cavity for placing and fixing the energy storage component 3. The bottom 53 is located at the end away from the base 21, and the energy storage component 3 needs to be installed into the retaining portion from the direction opposite to the third direction. The cross-sectional area of ​​the first limiting portion 51 in the third direction gradually increases along the third direction, and the cross-sectional area of ​​the second limiting portion 52 in the third direction gradually decreases along the third direction, so that the central axis L1 of the energy storage component is aligned with the first direction ( Figure 3 and Figure 4 A direction in the middle) forms a limiting effect of an included angle α.

[0054] refer to Figure 3 The first limiting portion 51 and the second limiting portion 52 extend along the third direction, and the bottom 53 is axially located at one end away from the base 21. The bottom 53 is detachably connected to the first limiting portion 51 and is integrally formed with the second limiting portion 52.

[0055] The retaining portion 5 can be manufactured using an injection molding process. During the manufacturing process, melted raw material for the retaining portion 5 is injected into a container. A mold is then inserted into the melted raw material to form the retaining portion 5 extending along the third direction. After the melted raw material solidifies and the retaining portion 5 is formed, the mold is removed.

[0056] The second limiting portion 52 is integrally formed with the bottom 53, and the first limiting portion 51 is detachably connected to the bottom 53. The first limiting portion 51, whose cross-sectional area in the third direction gradually increases along the third direction, is manufactured separately and detachably connected to the bottom 53, while the second limiting portion 52, whose cross-sectional area in the third direction gradually decreases along the third direction, is integrally formed with the bottom 53, which simplifies the difficulty of production and manufacturing and improves the convenience of production and manufacturing.

[0057] The first limiting portion 51 has a first end 511 close to the bottom 53 along the third direction and a second end 512 away from the bottom along the third direction. If the first limiting portion 51 and the bottom 53 are integrally formed, the distance between the first end 511 and the central axis L2 of the aerosol generating device is greater than the distance between the second end 512 and the central axis L2 of the aerosol generating device. This requires that the cross-sectional area of ​​the mold inserted into the melted raw material on the plane where the first end 511 is located is greater than the cross-sectional area of ​​the mold on the plane where the second end 512 is located. After waiting for the melted raw material to solidify, when the mold needs to be removed, it is impossible to completely remove the mold without destroying the structure of the integrally formed first limiting portion 51 and the bottom 53. Therefore, the production and manufacturing of the integrally formed first limiting portion 51 and the bottom 53 is difficult.

[0058] Since the cross-sectional area of ​​the second retaining portion 52 in the third direction gradually decreases along the third direction, the second retaining portion 52 has a tapered shape that gradually tapers in the third direction. This structure allows the mold inserted therein to be completely removed during the injection molding process. When the second retaining portion 52 and the base 53 are integrally formed, there is no difficulty in removing the mold. Designing the second retaining portion 52 and the base 53 to be integrally formed avoids the need to manufacture the second retaining portion 52 and the base 53 separately, reduces the number of additional parts required for the retaining portion 5, improves manufacturing convenience, and simplifies the manufacturing process.

[0059] According to another specific embodiment of the present invention, the retaining portion 5 is disposed circumferentially around the energy storage component 3, and the first limiting portion 51 is an elastic structure. Optionally, the first limiting portion 51 is made of one or more of foam, ethylene-vinyl acetate copolymer, silicone, or multi-layered fiber. Optionally, the first limiting portion 51 is an elastic plastic or metal structure, or includes an elastic component, such as a spring or a torsion spring.

[0060] In the above embodiments, the retaining portion 5 not only contacts the energy storage component 3 from one side or several contact points, but is tightly fitted along the entire circumference of the energy storage component 3. This circumferential and all-round contact provides 360-degree support and constraint for the energy storage component 3. Compared with point contact or line contact, the circumferential contact area is greatly increased. This causes the energy storage component 3 to be subjected to uniform restraint in the circumferential direction. When the aerosol generating device 100 is subjected to external impact, vibration or slight internal displacement, it is difficult for the energy storage component 3 to move or rotate significantly at any circumferential position. This design greatly enhances the stability of the energy storage component 3 inside the aerosol generating device 100, making it more firmly fixed.

[0061] In some embodiments, the retaining portion 5 can be independently disposed in the housing 1 , or can be disposed in the housing 1 and integrally formed with the housing 1 .

[0062] Furthermore, the material of the retaining portion 5 is one or more of foam, ethylene-vinyl acetate copolymer, silica gel, and multi-layer fiber, and the material of the retaining portion 5 is a flexible material with flexibility, elasticity, and compressibility. The flexible material can better adapt to the periphery of the energy storage component, forming a more fitting coating, and even if there are slight irregularities on the surface of the energy storage component, it can well accommodate the energy storage component 3. When the energy storage component 3 is a cylindrical battery, the retaining portion 5 can fit the curved surface of the energy storage component 3 to achieve good fixation. The energy storage component 3 is a flexible material, which can reduce the assembly force. When the energy storage component 3 is installed into the retaining portion 5 or when the retaining portion 5 is installed into the outer shell 1, the retaining portion 5 of the flexible material can be compressed or bent, thereby greatly reducing the insertion force or thrust required during the assembly process, so that the energy storage component 3 can be more easily installed in place, achieving a technical effect of easy installation. For the production system of the fully automatic assembly of the aerosol generating device 100, the wear and energy consumption of the production equipment can be reduced, and the risk of damage to the energy storage component 3 can be reduced. The holding portion 5 is made of a flexible material, so that the holding portion 5 has a certain buffering capacity, which can play a certain protective role for the energy storage component 3 during the assembly process.

[0063] According to another specific embodiment of the present invention, Figure 3 、 Figure 5 and Figure 6 As shown, the aerosol-generating device 100 further includes, located within the housing 1: an atomizing component 6 for heating an aerosol-generating substrate to generate an aerosol; a control component 7 for controlling the heating of the atomizing component 6, the control component 7 being axially disposed between the atomizing component 6 and the energy storage component 3; and a sealing ring 8 disposed on the periphery of the control component 7, between the inner wall of the housing 1 and the control component 7, thereby sealingly connecting the control component 7 to the housing 1. The sealing ring 8 divides the housing 1 into a first chamber 91 and a second chamber 92, which are distributed axially. The atomizing component 6 is located within the first chamber 91, and the energy storage component 3 is located within the second chamber 92. The gases in the first chamber 91 and the second chamber 92 are not connected.

[0064] In the above embodiments, the sealing ring 8 is disposed on the outer periphery of the control component 7 and between the inner wall of the housing 1 and the control component 7, thereby providing a sealed connection between the control component 7 and the housing 1. The sealing ring provides an airtight seal, preventing gas from flowing through the gap between the control component 7 and the inner wall of the housing 1, and thus is isolating the first chamber 91 from the second chamber 92.

[0065] On the one hand, when the energy storage component 3 is depressurized, a large amount of high-temperature and high-pressure gas is generated. Since the gases in the first chamber 91 and the second chamber 92 are not connected, the gas will not enter the first chamber 91 from the second chamber 92 where the energy storage component 3 is located. If there is no sealing ring, these gases may flow freely along the inner wall of the shell 1 and the gap between the components inside the shell. Since the control component 7 is located between the energy storage component 3 and the atomization component 6, the gas generated by the pressure release can easily flow to the first chamber where the atomization component 6 is located. Due to the presence of the sealing ring, even if the energy storage component 3 is depressurized, the high-temperature and high-pressure gas it generates will be confined to the second chamber 92 and will not affect the atomization process in the first chamber 91. More importantly, these high-temperature and high-pressure gases will not pass through the air path of the atomization component 6 and eventually be ejected from the nozzle, thereby avoiding the risk of the user directly inhaling the depressurized gas or being burned by the high-temperature and high-pressure gas, thereby improving the safety of use.

[0066] On the other hand, the sealing ring 8 not only prevents the flow of gas, but also prevents the penetration of condensate. During the operation of the atomizing component 6, especially during temperature changes, the aerosol encounters the cold inner wall of the atomizing component 6 to produce condensate, which may remain in the first chamber 91. The physical isolation effect of the sealing ring 8 prevents the condensate in the first chamber 01 from penetrating into the second chamber 92 through the gap between the control component 7 and the inner wall of the outer shell 1. Since the energy storage component 3 is located in the second chamber 92, the sealing ring 8 effectively prevents the condensate from contacting the energy storage component 3, such as a battery. Batteries are very sensitive to liquids (especially liquids containing conductive substances), and condensate may cause battery short circuits, performance degradation, or even damage. By isolating the condensate, the sealing ring 8 protects the energy storage component 3 from contamination, extends its service life, and improves the reliability of the aerosol generating device 100.

[0067] In some embodiments, the connection methods between the base 21 and the housing 1 include but are not limited to: snap connection, tight fit, screw fastening, pin connection, retaining ring limitation, gluing fixation, threaded connection, and compression connection.

[0068] According to another specific embodiment of the present invention, the base 21 is snap-fitted to the housing 1. The base 21 is provided with a pressure relief vent 211, which allows the base 21 to snap-fit ​​to the housing 1. The cross-sectional area of ​​the base 21 along the axial direction of the aerosol generating device 100 is greater than the cross-sectional area of ​​the pressure relief vent 211 along the axial direction of the aerosol generating device 100.

[0069] In the above-described embodiments, when the energy storage component 3 experiences mild or moderate thermal runaway, resulting in pressure buildup, the high-temperature, high-pressure gas generated internally is first discharged through the pressure relief vent 211, providing a buffering effect. The base 21 and the housing 1 utilize a relatively easy-to-detach connection, using a snap-fit ​​connection, rather than welding or threaded connections. Furthermore, the base 21 is provided with a pressure relief vent 211, the diameter of which is larger than the diameter of the pressure relief vent 211. When the energy storage component 3 experiences severe thermal runaway, and the resulting pressure far exceeds the designed pressure of the pressure relief vent 211, the internal pressure will rapidly increase. At this point, the pressure acting on the inner wall of the base 21 will overcome the restraining force of the snap-fit ​​connection. Because the base's diameter is larger than the diameter of the pressure relief vent 211, pressure acts not only on the pressure relief vent 211 but also on the contact area between the base 21 and the housing 1. When the pressure is sufficiently high, the base 21 will pop out and separate from the housing. When the base 21 is released, the bottom opening, previously sealed by the base 21, is opened, providing a pressure relief path with a larger cross-sectional area than the pressure relief vent 211. The increased cross-sectional area of ​​the pressure relief path allows the high-temperature and high-pressure gas accumulated inside the housing 1 to be quickly discharged at an exhaust speed exceeding the exhaust speed of the pressure relief port 211. This greatly reduces the risk of continued pressure increase caused by the accumulation of gas inside the aerosol generating device, and effectively avoids explosions or violent ruptures caused by the accumulation of high-temperature and high-pressure gas.
