Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic atomization technology, specifically to an aerosol generating device. Background Technology
[0002] With the increasing prevalence of aerosol generating devices, they are now ubiquitous in daily life and ordinary households. An aerosol generating device typically consists of a casing, atomizing components, and a power supply component. Among these, the power supply component, as the energy supply unit, has a significant impact on the safety of the entire aerosol generating device. The power supply component usually uses a rechargeable lithium battery as its energy storage component.
[0003] The energy storage component includes electrodes and a main body. The electrodes are mounted on the main body, with one end connected to an electrode inside the main body and the other end connected to the power supply circuit of the aerosol generator. A seam is formed at the electrodes by the covering unit of the main body. If the energy storage component is abnormally charged or experiences excessively high temperatures during use, thermal runaway may occur. If the energy storage component is located within the aerosol generator, it will release a large amount of high-temperature, high-pressure gas, leading to depressurization. Due to the seam between the electrodes and the covering unit, the high-temperature, high-pressure gas can be released from the seam into the aerosol generator. This high-temperature, high-pressure gas can accumulate inside the outer shell of the aerosol generator, causing excessive gas pressure and posing a risk of explosion. Furthermore, because the aerosol generator has a nozzle that connects to the outside, the large amount of high-temperature, high-pressure gas generated can easily be ejected from the nozzle, potentially causing the gas to flow towards the user, posing a depressurization safety issue.
[0004] Therefore, how to reduce the impact force of pressure relief release of the aerosol generating device base, reduce the risk of concentrated release of high-temperature and high-pressure gas directly along the axial direction, and improve the safety of the aerosol generating device has become an urgent technical problem to be solved. Utility Model Content
[0005] The purpose of this invention is to solve the problem of how to reduce the impact force of pressure relief release of the aerosol generating device base, reduce the risk of concentrated release of high-temperature and high-pressure gas directly along 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 a sidewall extending along a first direction; a base located at the bottom end of the housing; and an energy storage component located inside the housing, including an electrode located at one end of the energy storage component facing the base along the axial direction of the aerosol generating device; wherein the central axis of the energy storage component forms an angle of less than 90 degrees with the first direction.
[0007] Using the above technical solution, the electrode is located at the end of the energy storage component facing the base along the axial direction of the aerosol generating device. When the energy storage component is depressurized, the high-temperature, high-pressure gas generated by the depressurization will be released from the sealed position at the end of the energy storage component where the electrode is located. The side wall of the outer shell extends along the 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 will impact the base; and a component perpendicular to the side wall of the outer shell, which will impact the side wall. This results in the component force perpendicular to the base being less than the total impact force generated by the pressure relief. This means that the impact force acting on the base is weakened and dispersed, and is no longer entirely impacted on the base along the axial direction. Some of the impact force can be released on the side wall of the outer casing in the form of a component force perpendicular to the side wall, thereby reducing the impact force concentrated in the direction of the base. This reduces the risk of the high-temperature and high-pressure gas generated by the pressure relief being directly released along the axial direction, reduces the risk of the aerosol generating device exploding due to excessive pressure, and improves the safety of the aerosol generating device.
[0008] According to another specific embodiment of the present invention, the base is provided with a pressure relief port, which is connected to one end of the energy storage component where the electrode is located.
[0009] According to another specific embodiment of the present invention, the outer shell has a redundant space, which is located axially between the electrode and the base.
[0010] According to another specific embodiment of the present invention, the pressure relief port is a charging port, and the aerosol generating device further includes a charging management module. The charging management module includes a circuit board, which is located axially between the electrode and the charging port. The circuit board is connected to the charging port and to the electrode.
[0011] According to another specific embodiment of this utility model, the included angle ranges from 0.5 degrees to 5 degrees.
[0012] According to another specific embodiment of the present invention, the center of the energy storage component is located on the central axis of the aerosol generating device.
[0013] According to another specific embodiment of the present invention, the aerosol generating device further includes a holding part located inside the housing, the holding part clamping the energy storage component such that the central axis of the energy storage component forms an angle of less than 90 degrees with the first direction, the holding part clamping the energy storage component forms a clamping surface, and the extending direction of the clamping surface is the same as the extending direction of the side of the energy storage component.
[0014] According to another specific embodiment of the present invention, the holding part includes: a first limiting part; a second limiting part, which together with the first limiting part clamps the energy storage component; and a bottom, located axially away from the base, which is detachably connected to the first limiting part and integrally formed with the second limiting part. The first limiting part, the second limiting part, and the bottom together accommodate the energy storage component. The first limiting part and the second limiting part are arranged opposite to each other along a second direction, which is perpendicular to the axial direction. The first limiting part and the second limiting part extend along a third direction. The cross-sectional area of the first limiting part in the third direction gradually increases along the third direction, and the cross-sectional area of the second limiting part in the third direction gradually decreases along the third direction. The third direction is the direction from the mouth end of the outer shell along the axial direction to the bottom end of the outer shell. The mouth end of the outer shell is the end opposite to the bottom end along the axial direction.
[0015] According to another specific embodiment of the present invention, the retaining part is arranged circumferentially around the energy storage component, and the first limiting part is an elastic structure.
[0016] According to another specific embodiment of the present invention, it further includes, within the outer shell: an atomizing component for heating the aerosol generating matrix to generate an aerosol; a control component for controlling the heating of the atomizing component, the control component being axially disposed between the atomizing component and the energy storage component; and a sealing ring disposed on the outer periphery of the control component, located between the inner wall of the outer shell and the control component, such that the control component is sealed to the outer shell, the sealing ring dividing the outer shell into a first chamber and a second chamber distributed axially, the atomizing component being located in the first chamber and the energy storage component being located in the second chamber, the gases in the first chamber and the second chamber being not in communication.
[0017] According to another specific embodiment of the present invention, the base is snapped into the outer shell. Attached Figure Description

[0029] Figure 1 This is a schematic diagram of the structure of a prior art aerosol generating device. The aerosol generating device 100 includes a housing 1, the housing 1 having a sidewall 11 extending along a first direction. The first direction is... Figure 1The outer casing 1 has a nozzle end 12 and a bottom end 13 along the axial direction of the aerosol generating device 100. The aerosol generating device 100 also includes a base located at the bottom end of the outer casing 1. The electrode 31 is located at the end of the energy storage component 3 away from the base 21 along the axial direction of the aerosol generating device 100, and the central axis L1 of the energy storage component is parallel to the first direction. When the energy storage component 3 experiences an internal fault (such as a short circuit or overcharge), it will depressurize, generating a large amount of high-temperature and high-pressure gas. In this case, when the energy storage component 3 depressurizes, the high-temperature and high-pressure gas generated by the depressurization will rush out from the sealing point 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 towards the end away from the base 21, that is, generate an impact force towards the nozzle end, which may easily cause injury to the user.
[0030] Figure 2 This is a schematic diagram of another prior art aerosol generating device. The aerosol generating device 100 includes a housing 1, which has a sidewall 11 extending along a first direction. The first direction is... Figure 2 The aerosol generating device 100 also includes a base located at the bottom of the housing 1. The electrode 31 is located at the end of the energy storage component 3 facing the base 21 along the axial direction of the aerosol generating device 100. In this embodiment, the central axis L1 of the energy storage component is parallel to the first direction. In this situation, the impact force generated by the pressure relief will all impact the base 21, posing a risk that the high-temperature, high-pressure gas generated by the pressure relief will be directly and centrally released along the axial direction, 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 sidewall 11 extending along a first direction. The first direction is as follows: Figure 3 and Figure 4 The base 21 is located at the bottom end 13 of the outer casing 1. One end of the outer casing 1 along the axial direction of the aerosol generating device 100 is the nozzle 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 within the housing 1, in the X direction. The energy storage component 3 includes an electrode 31, which is located along the axial direction of the aerosol generating device 100. Figure 3 and Figure 4 The X-direction of the energy storage component is oriented towards one end of the base 21. The central axis L1 of the energy storage component is perpendicular to the first direction (…). Figure 3 and Figure 4 The energy storage component 3 is positioned such that its central axis L1 forms an angle α less than 90 degrees with the first direction (direction A). This orientation results in the energy storage component's central axis L1 being perpendicular to the first direction (direction A). Figure 3 and Figure 4The first direction (direction A) forms an angle α of less than 90 degrees. Further, the 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, lead, or 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 outer casing 1, the impact force generated by the pressure relief will all impact the base 21, resulting in a large impact force and a high risk of the high-temperature and high-pressure gas generated by the pressure relief being directly and centrally released along the axial direction. If the central axis L1 of the energy storage component is perpendicular to the extension direction of the side wall of the outer casing 1, the impact force generated by the pressure relief will all impact the side wall 11 of the outer casing 1, posing a risk of the side wall 11 cracking. Furthermore, if the central axis L1 of the energy storage component is perpendicular to the extension direction of the side wall of the outer casing 1, it occupies a large space perpendicular to the axial direction of the aerosol generating device 100, making it inconvenient for the user to hold.
[0033] In the above embodiment, electrode 31 is located along the axial direction of energy storage component 3 and aerosol generating device 100. Figure 3 and Figure 4 The energy storage component 3 is positioned so that when the energy storage component 3 is depressurized, the high-temperature and high-pressure gas generated by the depressurization will be released from the sealed position at the end where the electrode 31 of the energy storage component 3 is located. The side wall 11 of the outer shell 1 extends along the 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 position, the central axis L1 of the energy storage component forms an angle of less than 90 degrees with the first direction, and the impact force F generated by the depressurization can be decomposed into two components: a first component F1 perpendicular to the base 21, which will impact the base 21; and a second component F2 perpendicular to the side wall 11 of the outer shell 1, which will impact the side wall 11. This results in the first component force F1 perpendicular to the base 21 being less than the total impact force F generated by the pressure relief. This means that the impact force acting on the base 21 is weakened and dispersed, and is no longer entirely impacted on the base 21 along the axial direction. Part of the impact force can be released on the side wall of the outer shell in the form of a component force perpendicular to the side wall. The side wall 11 of the outer shell 1 bears part of the pressure relief impact force, thereby reducing the impact force concentrated in the base direction, reducing the risk of the high temperature and high pressure gas generated by the pressure relief being directly released along 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, electrode 31 is disposed along the axial direction of energy storage component 3 and aerosol generating device 100. Figure 3 and Figure 4 The end of the energy storage component (in the X direction) facing the base 21 is positioned so that when the energy storage component depressurizes, the high-temperature, high-pressure gas generated by the depressurization is prevented from escaping from the nozzle, reducing the risk of injury to the user. On the other hand, the central axis L1 of the energy storage component is aligned with the first direction (in the X direction). Figure 3 and Figure 4 The angle α formed by the A direction in the middle is 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 explosion of the aerosol generating device 100 due to excessive pressure.
[0035] In some embodiments, at least one electrode 31 of the energy storage component 3 is located along the axial direction of the energy storage component 3 and the aerosol generating device 100. Figure 3 and Figure 4 The end of the energy storage component 3 (in the X direction) facing the base 21. Further, the positive electrode 31 of the energy storage component 3 is located along the axial direction of the energy storage component 3 along the aerosol generating device 100 (in the X direction). Figure 3 and Figure 4 The end of the energy storage component 3 (in the X direction) facing the base 21. Furthermore, both electrodes 31 of the energy storage component 3 are located along the axial direction of the energy storage component 3 along the aerosol generating device 100 (in the X direction). Figure 3 and Figure 4 The X direction in the middle) is towards one end of the base 21.
[0036] According to another specific embodiment of this utility model, please continue to refer to... Figure 3 The base 21 is provided with a pressure relief port 211, which is connected to one end of the energy storage component 3 where the electrode 31 is located. Furthermore, the pressure relief port 211 is spatially connected to 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 inside the energy storage component 3 to be quickly discharged through 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 sealing point of the electrode 31. This effectively alleviates the accumulation of gas pressure generated by the energy storage component 3 inside the aerosol generating device 100, preventing the internal pressure of the aerosol generating device 100 from continuously and rapidly increasing. The pressure relief port 211 provided on the base 21 allows the gas inside the aerosol generating device 100 to be discharged in a timely manner. When the energy storage component 3 experiences abnormal pressure relief, 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 inside the aerosol generating device 100 and preventing the pressure from reaching a dangerous level that could cause 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 this utility model, please continue to refer to... Figure 3 The outer casing 1 has a redundant space 14, which is located axially between the electrode 31 and the base 21.
[0039] In the above 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 and high-pressure gas generated by depressurization, thereby improving safety. When the energy storage component 3 malfunctions and depressurizes, the internal pressure of the energy storage component 3 rises sharply and gas is released through the sealing position of the electrode 31. This instantaneously generated large amount of high-temperature and high-pressure gas requires a space for diffusion and containment. Without the redundant space 14 axially positioned between the electrode 31 and the base 21, the instantaneous gas pressure is too high and cannot be completely discharged. The pressure accumulates in a very small space, posing a risk of excessive internal pressure in the aerosol generating device 100, which could lead to physical rupture or explosion of the aerosol generating device 100. With the presence of the redundant space 14, the gas generated by depressurization will first enter this space. The redundant space 14 plays a buffering and containment role, preventing the gas from rushing out of the depressurization port 211 on the base 21 instantly and causing a large impact force. After the gas generated by depressurization enters the redundant space 14, it will expand and diffuse in this relatively large space, and its pressure and temperature will decrease accordingly. This significantly 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 also prolongs the gas ejection time, allowing the gas more time to be discharged through the pressure relief port, rather than being ejected instantaneously. The existence of the redundant space 14 also provides a certain directionality for the gas flow. After entering the redundant space 14, the gas can flow more evenly towards the base 21, rather than forming a concentrated impact flow. This helps to exhaust gas more effectively and reduce local high pressure or poor pressure relief caused by excessively concentrated gas flow. Due to the existence of the redundant space 14, even if the exhaust rate of the pressure relief port 211 cannot keep up with the gas generation rate of the energy storage component 3, the existence of the redundant space 14 can absorb some of the pressure increase, preventing the pressure inside the entire outer casing 1 from rising too high to the point that it may cause the outer casing 1 to rupture and explode.
[0040] In some embodiments, the base 21 seals the bottom end 13 of the housing 1 to prevent components inside the housing 1 from shifting or coming out of the housing 1.
[0041] According to another specific embodiment of this utility model, please continue to refer to... Figure 3 The pressure relief port 211 is a charging port. Further, the pressure relief port 211 is a TYPE-C charging port. The aerosol generating device 100 also includes a charging management module 4, which includes a circuit board 41. The circuit board 41 is located axially 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 bounced onto the side wall 11 of the outer shell 1, thereby dispersing part of the impact force hitting the base 21.
[0043] In the above embodiments, the pressure relief port 211 serves as both a charging connection port for the aerosol generating device 100 and an exhaust port. This integrates the charging connection port and the pressure relief port 211 into one, achieving functional integration and space optimization. The TYPE-C charging port itself has a through-hole structure with internal metal contacts and an external plastic or metal covering. However, there are usually channels between the contacts and between the contacts and the housing 1 or base 21. This structure is designed to serve as a channel for venting pressure-relief gas. When the internal pressure of 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. With this design, the pressure relief port 211 no longer needs to be a separate, additional exhaust structure. The pressure relief function is achieved directly using the essential interface structure of the TYPE-C charging port, thereby integrating the functions of pressure relief and charging. Since the pressure relief function is integrated into the TYPE-C charging port, there is no need to design, manufacture, and install an additional independent venting structure, thus directly saving some of the physical space occupied by the components.
[0044] In addition, the charging management module 4 includes a circuit board 41, which is located along the axial direction of the aerosol generating device 100 between the electrode 31 and the TYPE-C charging port, thus shortening the transmission path of current and electrical signals. By compactly arranging the electrode 31, circuit board 41, and integrated TYPE-C charging port of the energy storage component 3 along the axial direction, the overall structure of the aerosol generating device 100 becomes more compact, optimizing space and thereby miniaturizing the aerosol generating device 100.
[0045] According to a specific embodiment of this utility model, refer to Figure 4 The included 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 included angle α ranges from 0.5 degrees to 25 degrees. Preferably, the included angle α ranges from 0.5 degrees to 5 degrees. That is, the central axis L1 of the energy storage component and the first direction ( Figure 3 and Figure 4 The included angle α (direction A in the diagram) ranges from 0.5 degrees to 5 degrees. The first direction is the extension direction of the side wall 11 of the outer shell 1. Experiments have shown that when the included angle α is in the range of 0.5 degrees to 5 degrees, the ratio of the pressure relief impact force borne by the base 21 and the side wall 11 is most suitable, achieving the best 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 angle α between the base 21 and the side wall 11 of the outer casing 1 ranges from 0.5 degrees to 5 degrees. The energy storage component 3 is inclined relative to the extension direction of the side wall 11 of the outer casing 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, which impacts the base 21; and a second component F2 perpendicular to the side wall 11 of the outer casing 1, which impacts the side wall 11. The larger the angle α, the larger the second component F2 and the smaller the first component F1. Within this angle α range, the impact force F can be well dispersed while maximizing the use of the space along the first direction of the outer casing, avoiding excessive occupation of the space perpendicular to the side wall, and making it convenient for the user to hold the aerosol generating device. If the space of the aerosol generating device in the vertical direction is too large, it will be inconvenient for the user to hold, resulting in a poor user experience. The included angle α ranges from 0.5 degrees to 5 degrees, achieving a balance between pressure relief safety and device miniaturization. This avoids both an excessively small included angle α leading to ineffective dispersion of the impact force F and an excessively large included angle α occupying too much internal space of the outer casing 1. If the angle between the central axis L1 of the energy storage component and the extension direction of the side wall 11 of the outer casing 1 is greater than 5 degrees, the energy storage component 3 occupies a large amount of space perpendicular to the axial direction of the aerosol generating device 100, which is detrimental to the miniaturization of the aerosol generating device 100. By using an included angle α range of 0.5 degrees to 5 degrees, the proportion of the force components acting on the base 21 and the side wall 11 is precisely adjusted, optimizing the release path of the pressure relief gas and achieving the best 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 the above embodiments, the center O of the energy storage component is located on the central axis L2 of the aerosol generating device. This places the energy storage component 3 in a relatively central position relative to the aerosol generating device 100, without deviating from the side of the aerosol generating device 100 located on the central axis L2. 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 to one side in the direction perpendicular to the central axis L2. If the center O of the energy storage component is not located on the central axis L2 of the aerosol generating device, but is biased to one side, then in order to accommodate this biased energy storage component 3, the outer casing 1 needs to provide additional space on the opposite side, making the aerosol generating device 100 symmetrical along its central axis L2. This results 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 inside the aerosol generating device 100 can be utilized to the maximum extent. The energy storage component 3 does not occupy too much space on one side, making the internal layout of the aerosol generating device more compact. By avoiding the additional space requirements caused by eccentric placement, the effective volume occupied by the energy storage component (the volume accommodating the energy storage component 3 and the volume freed up by the axisymmetry 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 specific embodiment of the present invention, the aerosol generating device 100 further includes a holding part 5 located inside the housing 1, the holding part 5 clamping the energy storage component 3, such that the central axis L1 of the energy storage component is aligned with the first direction ( Figure 3 and Figure 4 The retaining part 5 forms an angle α of less than 90 degrees with the energy storage component 3 in the direction of A. The retaining part 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 of the energy storage component 3. That is, the retaining part 5 clamps the side of the energy storage component 3 to form a clamping surface 54.
[0051] In the above embodiments, the retaining part 5 clamps the energy storage component 3 such 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 is inclined relative to the extending direction of the side wall 11 of the outer casing 1. Through the design of the retaining part 5 clamping the energy storage component 3, the retaining part 5 can forcibly fix the energy storage component 3 in a specific inclined placement orientation. In this placement orientation, the central axis L1 of the energy storage component is inclined relative to the first direction (…). Figure 3 and Figure 4 An angle α is formed between the holding part 5 and the first direction (direction A). Without the holding part 5, the energy storage component 3 may be parallel or perpendicular to the extending direction of the side wall 11 of the housing 1 due to gravity or assembly errors. Furthermore, the holding part 5 clamps the energy storage component to form a clamping surface 54, the extending direction of the clamping surface 54 being the same as the extending direction of the side of the energy storage component 3, thus more stably fixing the energy storage component 3 within the housing 1. Through physical contact and constraint, the holding part 5 continuously and stably maintains the angle between the central axis L1 of the energy storage component and the first direction at less than 90 degrees. Even if subjected to slight vibration or impact during use, the angle between the central axis L1 of the energy storage component and the first direction remains stable. The extending direction of the clamping surface 54 is consistent with the extending direction of the energy storage component 3, and the tight fit reduces the possibility of displacement of the energy storage component under the action of clamping force, and reduces the possibility of the energy storage component 3 sliding or rotating within the holding part 5.
[0052] According to another specific embodiment of this utility model, please continue to refer to... Figure 3 The holding part 5 includes: a first limiting part 51; and a second limiting part 52, which together with the first limiting part 51 clamp the energy storage component 3. The holding part 5 also includes a bottom 53, which extends axially ( Figure 3 and Figure 4 The bottom 53 (in the X direction) is located at the end furthest from the base 21. It is detachably connected to the first limiting part 51 and integrally formed with the second limiting part 52. The first limiting part 51, the second limiting part 52, and the bottom 53 together accommodate the energy storage component 3. The first limiting part 51 and the second limiting part 52 are located along the second direction (in the X direction). Figure 3 The Y-direction in the middle is set relative to the second direction ( Figure 3 The Y direction in the middle is perpendicular to the axis. Figure 3 and Figure 4 (Central X direction). The first limiting part 51 and the second limiting part 52 are along the third direction ( Figure 3 Extending in the direction B, the cross-sectional area of the first limiting part 51 in the third direction gradually increases along the third direction, and the cross-sectional area of the second limiting part 52 in the third direction gradually decreases along the third direction. The third direction is the direction from the mouth end 12 of the outer shell 1 along the axial direction to the bottom end 13 of the outer shell 1. The mouth end 12 of the outer shell 1 is the end opposite to the bottom end 13 along the axial direction.
[0053] In the above embodiment, the holding part 5 includes a first limiting part 51, a second limiting part 52, and a bottom 53, which together accommodate the energy storage component 3. The bottom end has an opening at one end opposite to the first limiting part 51 in the third direction for accommodating the energy storage component 3. The bottom 53 is detachably connected to the first limiting part 51, and the bottom 53 is integrally formed with the second limiting part 52. The cross-sectional area of the first limiting part 51 in the third direction gradually increases along the third direction, while the cross-sectional area of the second limiting part 52 in the third direction gradually decreases along the third direction. The first limiting part 51 and the second limiting part 52 are aligned along a second direction (…). Figure 3 The first limiting part 51, the second limiting part 52, and the bottom 53 are arranged opposite to each other in the Y direction (in the middle direction) to jointly clamp the energy storage component 3, while the bottom 53 forms a closed end. The first limiting part 51, the second limiting part 52, and the bottom 53 together form a receiving 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 inserted into the holding part from the direction opposite to the third direction. The design of the cross-sectional area of the first limiting part 51 gradually increasing in the third direction and the cross-sectional area of the second limiting part 52 gradually decreasing in the third direction achieves the goal of aligning the central axis L1 of the energy storage component with the first direction (in the Y direction) and the first direction (in the Y direction). Figure 3 and Figure 4 The angle α formed between the A direction and the limiting function is formed.
[0054] refer to Figure 3 The first limiting part 51 and the second limiting part 52 extend in a third direction, and the bottom part 53 is located axially at one end away from the base 21. The bottom part 53 is detachably connected to the first limiting part 51 and integrally formed with the second limiting part 52.
[0055] The retaining part 5 can be manufactured using an injection molding process. During manufacturing, molten raw material for the retaining part 5 is injected into a container, and then a mold is inserted into the molten material to form a retaining part 5 extending in a third direction. After the molten material solidifies and the retaining part 5 is formed, the mold is removed.
[0056] By integrally forming the second limiting part 52 with the bottom 53, and detachably connecting the first limiting part 51 with the bottom 53, the first limiting part 51, whose cross-sectional area gradually increases in the third direction, is manufactured separately and detachably connected to the bottom 53, while the second limiting part 52, whose cross-sectional area gradually decreases in the third direction, is integrally formed with the bottom 53. This simplifies the manufacturing difficulty and improves the convenience of manufacturing.
[0057] The first limiting part 51 has a first end 511 near the bottom 53 along a third direction and a second end 512 away from the bottom along a third direction. If the first limiting part 51 is integrally formed with the bottom 53, the distance from the first end 511 to the central axis L2 of the aerosol generating device is greater than the distance from the second end 512 to the central axis L2 of the aerosol generating device. This requires that the cross-sectional area of the mold inserted into the molten 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 the molten raw material has solidified, when it is necessary to remove the mold, it is impossible to remove the mold completely without damaging the structure of the integrally formed first limiting part 51 and bottom 53. Therefore, the manufacturing of the integrally formed first limiting part 51 and bottom 53 is difficult.
[0058] The second limiting part 52, with its tapered shape that gradually decreases in cross-sectional area along the third direction, allows for complete removal of the mold insert during injection molding. When the second limiting part 52 and the bottom 53 are integrally molded, there is no difficulty in removing the mold. Designing the second limiting part 52 and the bottom 53 as an integral unit avoids the need for separate production of each, reducing the number of additional parts required for the retaining part 5, improving manufacturing convenience, and simplifying the manufacturing process.
[0059] According to another specific embodiment of the present invention, the retaining part 5 is arranged circumferentially around the energy storage component 3, and the first limiting part 51 is an elastic structure. Optionally, the material of the first limiting part 51 is one or more of foam, ethylene-vinyl acetate copolymer, silicone, and multilayer fiber. Optionally, the first limiting part 51 is an elastic plastic or metal structure, or the first limiting part 51 includes an elastic component, such as a spring or torsion spring.
[0060] In the above embodiments, the retaining part 5 does not only contact the energy storage component 3 from one side or a few contact points, but also fits tightly along the entire circumference of the energy storage component 3. This omnidirectional circumferential contact provides 360-degree support and constraint for the energy storage component 3. Compared to point contact or line contact, the circumferential contact area is greatly increased. This makes the energy storage component 3 subject to uniform constraint force in the circumferential direction. When the aerosol generating device 100 is subjected to external impact, vibration, or internal slight displacement, the energy storage component 3 is unlikely to move or rotate significantly at any position in the circumferential direction. This design greatly enhances the stability of the energy storage component 3 inside the aerosol generating device 100, making it more securely fixed.
[0061] In some embodiments, the retaining part 5 may be disposed independently within the housing 1, or it may be disposed within the housing 1 and integrally formed with the housing 1.
[0062] Furthermore, the retaining part 5 is made of one or more of the following materials: foam, ethylene-vinyl acetate copolymer, silicone, and multilayer fibers. The retaining part 5 is made of a flexible material, possessing flexibility, elasticity, and compressibility. The flexible material can better adapt to the outer periphery of the energy storage component, forming a more closely fitting enclosure. Even if the surface of the energy storage component has slight irregularities, it can still effectively contain the energy storage component 3. When the energy storage component 3 is a cylindrical battery, the retaining part 5 can conform to the curved surface of the energy storage component 3, achieving good fixation. The flexible material of the energy storage component 3 reduces assembly force. When the energy storage component 3 is inserted into the retaining part 5 or the retaining part 5 is inserted into the outer casing 1, the flexible material retaining part 5 can be compressed or bent, thereby greatly reducing the insertion or pushing force required during assembly, making it easier to install the energy storage component 3 and achieving the technical effect of easy installation. For the production system of the fully automated aerosol generating device 100, this can reduce wear and energy consumption of the production equipment and reduce the risk of damaging the energy storage component 3. The retaining part 5 is made of flexible material, which gives it a certain buffering capacity and can protect the energy storage component 3 during the assembly process.
[0063] According to another specific embodiment of this utility model, such as Figure 3 , Figure 5 and Figure 6 As shown, the aerosol generating device 100 further includes, within the housing 1: an atomizing component 6 for heating the aerosol generating matrix to generate 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 outer periphery of the control component 7, located between the inner wall of the housing 1 and the control component 7, thereby sealing the control component 7 with the housing 1. The sealing ring 8 divides the housing 1 into a first chamber 91 and a second chamber 92 distributed axially, with the atomizing component 6 located in the first chamber 91 and the energy storage component 3 located in the second chamber 92, and the gases in the first chamber 91 and the second chamber 92 not communicating.
[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 sealing 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 the first chamber 91 and the second chamber 92 are not in communication.
[0065] On the one hand, when the energy storage component 3 depressurizes, generating a large amount of high-temperature, high-pressure gas, the gas will not enter the first chamber 91 from the second chamber 92 where the energy storage component 3 is located because the gases in the first chamber 91 and the second chamber 92 are not connected. Without the sealing ring, this gas might flow freely along the inner wall of the outer shell 1 and the gaps between the components inside the outer shell. Since the control component 7 is located between the energy storage component 3 and the atomizing component 6, the gas generated by the depressurization could easily flow to the first chamber where the atomizing component 6 is located. Due to the presence of the sealing ring, even if the energy storage component 3 depressurizes, the high-temperature, high-pressure gas it generates will be confined within the second chamber 92 and will not affect the atomization process in the first chamber 91. More importantly, this high-temperature, high-pressure gas will not ultimately be ejected from the nozzle through the air passage of the atomizing component 6, thereby avoiding the risk of the user directly inhaling the depressurized gas or being burned by the high-temperature, high-pressure gas, thus improving the safety of use.
[0066] On the other hand, the sealing ring 8 not only prevents gas flow but also prevents condensate penetration. During operation, especially during temperature changes, the aerosol encounters the cold inner wall of the atomizing component 6, generating condensate that may remain in the first chamber 91. The physical isolation provided by the sealing ring 8 prevents condensate in the first chamber 91 from penetrating into the second chamber 92 through the gap between the control component 7 and the inner wall of the outer casing 1. Since the energy storage component 3 is located in the second chamber 92, the sealing ring 8 effectively prevents condensate from contacting the energy storage component 3, such as a battery. Batteries are very sensitive to liquids (especially those containing conductive substances), and condensate can cause short circuits, performance degradation, or even damage to the battery. 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-fit, tight fit, screw fastening, pin connection, retaining ring limiting, glue fixing, threaded connection, and compression connection.
[0068] According to another specific embodiment of this utility model, the base 21 is snapped into the outer shell 1. Because the base 21 is provided with a pressure relief port 211, the base 21 is snapped into the outer shell 1. The cross-sectional area of the base 21 along the axial direction of the aerosol generating device 100 is larger than the cross-sectional area of the pressure relief port 211 along the axial direction of the aerosol generating device 100.
[0069] In the above embodiments, when the energy storage component 3 experiences slight or moderate thermal runaway leading to pressure buildup, the high-temperature, high-pressure gas generated internally will first be discharged through the pressure relief port 211, providing a certain buffering effect. The base 21 and the outer shell 1 are connected by a snap-fit connection, which is relatively easy to separate, rather than welding or threaded connections. Simultaneously, the base 21 is provided with a pressure relief port 211, and the diameter of the base 21 is larger than the diameter of the pressure relief port 211. When the energy storage component 3 experiences severe thermal runaway, and the resulting pressure far exceeds the design pressure of the pressure relief port 211, the internal pressure will rise rapidly. At this time, the pressure acting on the inner wall of the base 21 will overcome the constraint force of the snap-fit connection. Since the diameter of the base is larger than the diameter of the pressure relief port 211, the pressure acts not only on the pressure relief port 211 but also on the area where the base 21 contacts the outer shell 1. When the pressure is sufficiently high, the base will pop out and separate from the outer shell. After the base 21 detaches, the bottom opening, which was originally closed by the base 21, is opened, providing a pressure relief path with a larger cross-sectional area than the pressure relief port 211. The increased cross-sectional area of the pressure relief path allows the high-temperature, high-pressure gas accumulated inside the outer casing 1 to be rapidly discharged at a rate exceeding that of the pressure relief port 211. This significantly reduces the risk of continuous pressure increases due to gas accumulation inside the aerosol generating device, effectively preventing explosions or violent ruptures caused by the accumulation of high-temperature, high-pressure gas.

Those skilled in the art can make various changes in form and detail, including several simple deductions or substitutions, without departing from the spirit and scope of the present invention.
