Description

Technical Field

[0001] The present invention relates to the field of atomization technology, in particular to a material storage component and an aerosol generating device. Background Art

[0002] Cigarette smoke contains harmful substances such as tar. Long-term inhalation of these substances can be extremely harmful to the human body. To combat the harmful effects of cigarette smoke, aerosol-generating devices have emerged. Their core principle is to heat and atomize an aerosol-generating substrate through an atomizer, creating an inhalable aerosol. The performance of the atomizer directly impacts the taste, user experience, and safety of the aerosol.

[0003] However, most traditional aerosol-generating devices use a passive oil supply method, where the atomizer core relies on a continuous supply of oil from the surrounding oil reservoir. This method offers no control over oil flow, meaning the atomizer core is typically supplied with oil from the surrounding oil reservoir, regardless of the atomizer core's operating state. This can easily lead to oil leaks. Furthermore, the high temperature of the atomizer core can easily transfer heat to the surrounding oil reservoir, affecting the quality of unused oil. Furthermore, air pressure management is a crucial factor in the design and use of the oil reservoir. As the oil level decreases, the negative pressure within the reservoir gradually increases, affecting the oil transfer rate. Specifically, this increased negative pressure can hinder the flow of oil between the reservoir and the atomizer, resulting in inconsistent oil supply rates. When the negative pressure within the reservoir is excessive, the oil supply may be insufficient, leading to dry burning. This not only affects the user experience but can also damage the device. Insufficient oil supply will also lead to inconsistent taste when smoking. Users may feel fluctuations in the amount of smoke and changes in taste during use, affecting the overall smoking experience.

[0004] The above information disclosed in the background of this application is only used to understand the background of the concept of this application, and does not indicate or suggest that it contains information of the prior art. Summary of the Invention

[0005] Based on this, it is necessary to provide an electrical connector, a power supply device and an aerosol generating device to address the above problems.

[0006] A material storage assembly, comprising:

[0007] a housing, wherein the interior of the housing is hollow and has a mounting opening; and

[0008] A ventilation structure, which is hermetically embedded in the installation opening and encloses with the inner surface of the housing to form a storage cavity for loading an aerosol - generating substrate. An outlet is provided in either the housing or the ventilation structure and is in communication with the storage cavity. The outlet is used to extract the aerosol - generating substrate and supply it to the atomization assembly;

[0009] Wherein, the ventilation structure can elastically deform according to the stock of the aerosol - generating substrate in the storage cavity to adjust the capacity of the storage cavity.

[0010] The above - mentioned storage assembly can at least achieve the following beneficial effects: An outlet in communication with the storage cavity is provided in either the housing or the ventilation structure, which facilitates the extraction of the aerosol - generating substrate in the storage cavity and its supply to the atomization assembly. The ventilation structure can elastically deform according to the quantity of the aerosol - generating substrate in the storage cavity to dynamically adjust the capacity of the storage cavity, avoid excessive negative pressure in the storage cavity, ensure stable and sufficient oil supply to the atomization assembly, and avoid the dry - burning phenomenon caused by insufficient oil supply. When the aerosol - generating substrate in the storage cavity decreases, the ventilation structure contracts inward to reduce the capacity of the storage cavity; when the aerosol - generating substrate in the storage cavity increases, the ventilation structure expands outward to increase the capacity of the storage cavity. This dynamic adjustment function enables the storage assembly to adapt to different stocks of the aerosol - generating substrate, ensuring that the aerosol - generating substrate in the storage cavity can be fully and smoothly supplied from the outlet. It can be understood that during the process of the gradual reduction of the aerosol - generating substrate in the storage cavity, the elastic deformation of the ventilation structure can balance the pressure in the storage cavity. If the ventilation structure does not contract inward to the storage cavity to reduce its capacity, a vacuum negative - pressure area will be formed in the storage cavity, affecting the smooth supply of the aerosol - generating substrate from the outlet.

[0011] In some embodiments, the storage assembly further includes a bottom cover, which is covered on the side of the ventilation structure facing away from the storage cavity and is connected to the housing. The bottom cover is provided with ventilation holes. The arrangement of the ventilation holes enables air pressure balance between the storage cavity and the external environment. When the ventilation structure elastically deforms due to the reduction of the aerosol - generating substrate, outside air can enter the space between the ventilation structure and the bottom cover through the ventilation holes, avoiding problems such as unsmooth oil supply caused by air - pressure changes. It can be understood that during the process of the gradual reduction of the aerosol - generating substrate in the storage cavity, the ventilation structure contracts inward. Without ventilation holes, a vacuum negative - pressure area may be formed between the ventilation structure and the bottom cover, hindering further deformation of the ventilation structure. The design of the ventilation holes effectively avoids this phenomenon, ensuring the normal operation of the ventilation structure.

[0012] In some of these embodiments, when the quantity of the aerosol - generating matrix in the storage cavity increases, the ventilation structure can elastically deform according to the stock of the aerosol - generating matrix in the storage cavity to increase the capacity of the storage cavity. The gas on the side of the ventilation structure facing away from the storage cavity can be discharged from the ventilation holes to maintain the air - pressure balance between the storage cavity and the outside; when the quantity of the aerosol - generating matrix in the storage cavity decreases, the ventilation structure can elastically deform according to the stock of the aerosol - generating matrix in the storage cavity to decrease the capacity of the storage cavity, and the side of the ventilation structure facing away from the storage cavity can receive gas from the outside through the ventilation holes to maintain the air - pressure balance between the storage cavity and the outside. When the quantity of the aerosol - generating matrix in the storage cavity increases, the ventilation structure can expand outwards according to the stock of the aerosol - generating matrix in the storage cavity to increase the capacity of the storage cavity. During this process, the gas on the side of the ventilation structure facing away from the storage cavity can be discharged through the ventilation holes opened on the bottom cover, thus maintaining the air - pressure balance between the storage cavity and the outside. This design avoids the problem of increased air pressure caused by the increase in the aerosol - generating matrix and ensures the pressure stability inside the device. When the quantity of the aerosol - generating matrix in the storage cavity decreases, the ventilation structure can contract inwards according to the stock of the aerosol - generating matrix in the storage cavity to decrease the capacity of the storage cavity. During this process, the side of the ventilation structure facing away from the storage cavity can receive gas from the outside through the ventilation holes opened on the bottom cover, thus maintaining the air - pressure balance between the storage cavity and the outside. This design avoids the negative - pressure problem caused by the decrease in the aerosol - generating matrix and ensures the pressure stability inside the device.

[0013] In some of these embodiments, the bottom cover is detachably connected to the housing. The detachable connection between the bottom cover and the housing not only facilitates assembly during manufacturing but also allows the bottom cover to be easily disassembled later, thus facilitating the maintenance of the storage cavity, the ventilation structure, and other internal components.

[0014] In some of these embodiments, a plurality of first clamping portions are spaced apart from each other on the periphery of the bottom cover, and a plurality of second clamping portions are spaced apart from each other on the periphery of the mounting opening of the housing. The first clamping portions and the second clamping portions correspond to each other one by one, and the bottom cover is clamped to the housing by the cooperation of the plurality of first clamping portions and the plurality of second clamping portions.

[0015] In some of these embodiments, either the bottom cover or the air exchange structure is provided with a limiting convex portion, and the other of the bottom cover and the air exchange structure is provided with a limiting concave portion. The limiting convex portion is inserted into the limiting concave portion to limit the relative position between the bottom cover and the air exchange structure. The design of the limiting structure makes the assembly of the bottom cover and the air exchange structure simpler and more efficient. The precise positioning between the bottom cover and the air exchange structure can be completed by simply aligning the limiting convex portion and inserting it into the limiting concave portion, avoiding assembly errors or functional abnormalities caused by position deviation and reducing the assembly difficulty. Through the constraint of the limiting structure, the relative position between the bottom cover and the air exchange structure is fixed, enhancing the stability of the overall structure and preventing loosening or displacement during the operation of the device.

[0016] In some of these embodiments, the bottom cover is provided with a through hole, and the air exchange structure is provided with a discharge pipe. The end of the discharge pipe is provided with the discharge port, and the discharge pipe is communicated with the through hole or the discharge pipe passes through the through hole.

[0017] In some of these embodiments, the air exchange structure includes an annular portion and a deformable portion connected to the annular portion. The annular portion is hermetically embedded in the installation opening, and the deformable portion can be switched between an extended form and a folded form; when the deformable portion is in the extended form, the capacity of the storage cavity is the largest; when the deformable portion is in the folded form, the capacity of the storage cavity is the smallest; during the process of the deformable portion switching from the extended form to the folded form, the deformable portion moves in a direction close to the installation opening; during the process of switching from the folded form to the extended form, the deformable portion moves in a direction away from the installation opening. The annular portion is hermetically embedded in the installation opening to ensure a tight and leak-free connection between the air exchange structure and the installation opening, preventing the aerosol generation matrix in the storage cavity from leaking. When the deformable portion switches its form, its movement does not damage the sealing performance, ensuring that the storage cavity can maintain a reliable sealing performance in different capacity states. The deformable portion can be switched between the extended form and the folded form, enabling the capacity of the storage cavity to be dynamically adjusted between the maximum capacity and the minimum capacity according to actual needs.

[0018] In some of these embodiments, a first auxiliary fold is formed at the junction of the deformable portion and the annular portion, surrounding the annular portion. During the process of the deformable portion switching from the extended form to the folded form, the first auxiliary fold can assist the deformable portion to move in the direction close to the mounting opening and fold within the annular portion. When the deformable portion switches from the extended form to the folded form, the first auxiliary fold can assist the deformable portion to move in the direction close to the mounting opening, ensuring that the folding process is smoother and more accurate. Moreover, the design of the first auxiliary fold reduces the resistance between the deformable portion and the annular portion during the folding process, making the folding easier and more efficient. The design of the first auxiliary fold makes the folding movement of the deformable portion more controllable, avoiding jamming or deformation caused by disordered movement, and ensuring the accuracy and reliability of the folding process. The first auxiliary fold can also reduce the stress concentration of the material during repeated folding, reducing the risk of material fatigue and damage. With the assistance of the first auxiliary fold, the deformable portion in the folded form can be tightly folded within the annular portion, maximizing the capacity of the material storage cavity.

[0019] In some of these embodiments, the deformable portion includes a plurality of folding bodies sequentially stacked and connected to the annular portion. A second auxiliary fold is formed at the junction of any two adjacent folding bodies. During the process of the deformable portion switching from the extended form to the folded form, the second auxiliary fold can assist the upper folding body to move in the direction close to the mounting opening and fold within the lower folding body. The deformable portion is formed by sequentially stacking and connecting a plurality of folding bodies, and each folding body can be independently folded to form a hierarchical folding structure. Each folding body is connected to the adjacent folding body through the second auxiliary fold. During the folding process, the upper folding body can move in the direction close to the mounting opening and fold within the lower folding body, realizing segmented folding and ensuring the uniformity and stability of the folding process. When the deformable portion switches from the extended form to the folded form, the second auxiliary fold can assist the upper folding body to move in the direction close to the mounting opening, making the folding movement of each folding body more controllable, avoiding jamming or deformation caused by disordered movement, and enabling the folding bodies to smoothly transition during the folding process, ensuring the accuracy and reliability of the folding process. The design of the second auxiliary fold reduces the resistance between adjacent folding bodies, making the folding process smoother and more efficient, and avoiding jamming or deformation caused by excessive resistance. The hierarchical folding structure enables the deformable portion in the folded form to be tightly folded, maximizing the capacity of the material storage cavity.

[0020] In some of these embodiments, the folding body includes a first folding body and a second folding body that are sequentially stacked and connected to the annular portion. A first auxiliary fold is formed at the connection between the first folding body and the annular portion. A second auxiliary fold that surrounds the first folding body is formed at the connection between the second folding body and the first folding body. During the process of the deformation portion switching from the extended form to the folded form, the second auxiliary fold can assist the second folding body to move in the direction close to the mounting opening and fold within the first folding body. When the deformation portion switches from the extended form to the folded form, the first auxiliary fold can guide the first folding body to move in the direction close to the mounting opening, and the second auxiliary fold can assist the second folding body to move in the direction close to the mounting opening and fold within the first folding body, further optimizing the folding effect and ensuring the uniformity and stability of the folding process. This segmented folding makes the folding of the deformation portion more uniform and controllable. The second folding body folds within the first folding body, enabling the deformation portion to be tightly folded, maximizing the capacity of the material storage cavity.

[0021] In some of these embodiments, when the deformation portion is in the folded form, the second folding body folds within the first folding body and its cross-sectional profile is M-shaped. The second folding body can be tightly folded within the first folding body to form a substantially M-shaped folding structure, minimizing the occupied space and increasing the capacity of the material storage cavity. In addition, the symmetry of the M-shaped structure makes the stress distribution during the folding process more uniform, avoiding deformation or damage caused by local stress concentration and ensuring the stability of the folded form.

[0022] In some of these embodiments, a third auxiliary fold is formed on the side of the second folding body facing away from the mounting opening. When the deformation portion is in the folded form, the second folding body is folded in half along the third auxiliary fold. The third auxiliary fold provides a clear folding guide for the second folding body, ensuring that it is folded in half along a predetermined direction, making the folding process of the second folding body more orderly and controllable, avoiding jamming or deformation caused by disorderly folding, and ensuring the smoothness and efficiency of the folding process.

[0023] In some of these embodiments, the thickness of the first auxiliary fold is less than the thickness of the annular portion.

[0024] In some of these embodiments, the thickness of the first auxiliary fold is less than the thickness of the folding body. The reduction in the thickness of the first auxiliary fold makes this area more easily bendable during the folding process, enabling it to more precisely guide the deformation portion to move in the direction close to the mounting opening, avoiding deviation or jamming during the folding process, improving the accuracy and controllability of folding, and ensuring a smoother folding process.

[0025] In some of these embodiments, the thickness of the second auxiliary fold is less than the thickness of the folded body. The thickness of the second auxiliary fold is thinned, making this area more bendable during the folding process, enabling more precise guidance of the folded body to move in the direction close to the installation opening, avoiding deviation or jamming during the folding process, enhancing the accuracy and controllability of folding, and ensuring a smoother folding process.

[0026] In some of these embodiments, the ventilation structure includes at least one of silicone and rubber. Silicone has good flexibility and elasticity, can withstand multiple bends and stretches without being easily deformed, and is suitable for application scenarios that require frequent deformation. Rubber has excellent wear resistance, can withstand long-term use and friction, extends the service life of the ventilation structure, and is not easily aged during long-term use, being able to maintain stable performance, and is suitable for application scenarios that require long-term use.

[0027] In some of these embodiments, the housing is a transparent housing. The transparent housing makes the internal structure and working state of the device visible, facilitating the user to know the stock of the aerosol generation matrix in real time.

[0028] This application also provides an aerosol generation device, which includes an atomization component and a storage component as described in any of the above embodiments.

[0029] For the above aerosol generation device, the storage component described in the above embodiments can be provided therein. Therefore, the aerosol generation device also has at least the following beneficial effects: An outlet communicating with the storage cavity is provided in either the housing or the ventilation structure of the storage component of the aerosol generation device, facilitating the extraction of the aerosol generation matrix in the storage cavity and supplying it to the atomization component. The ventilation structure can elastically deform according to the quantity of the aerosol generation matrix in the storage cavity, dynamically adjusting the capacity of the storage cavity, avoiding excessive negative pressure in the storage cavity, ensuring stable and sufficient oil supply to the atomization component, and avoiding the dry burning phenomenon caused by insufficient oil supply. When the aerosol generation matrix in the storage cavity decreases, the ventilation structure contracts inward, reducing the capacity of the storage cavity; when the aerosol generation matrix in the storage cavity increases, the ventilation structure expands outward, increasing the capacity of the storage cavity. This dynamic adjustment function enables the storage component to adapt to different stocks of the aerosol generation matrix, ensuring that the aerosol generation matrix in the storage cavity can be fully and smoothly supplied from the outlet. It can be understood that during the process of the gradual reduction of the aerosol generation matrix in the storage cavity, the elastic deformation of the ventilation structure can balance the pressure in the storage cavity. If the ventilation structure does not contract inward into the storage cavity to reduce the capacity of the storage cavity, a vacuum negative pressure area will be formed in the storage cavity, affecting the smooth supply of the aerosol generation matrix from the outlet.

Detailed implementation manners

[0042] To make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention in conjunction with the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0043] Please refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 , in some implementation manners, the present application provides a material storage assembly 300, which includes a housing 320 and a ventilation structure 310. The interior of the housing 320 is hollow and provided with an installation opening 321. The ventilation structure 310 is hermetically embedded in the installation opening 321. The ventilation structure and the inner surface of the housing 320 enclose a material storage cavity 330 for loading an aerosol generating substrate. An outlet 314 communicating with the material storage cavity 330 is provided in either one of the housing 320 and the ventilation structure 310. The outlet 314 is used to extract the aerosol generating substrate for supply to the atomizing assembly 100. As Figure 6 , Figure 7 , Figure 8 and Figure 9 shown, the ventilation structure 310 can elastically deform according to the stock of the aerosol generating substrate in the material storage cavity 330 to adjust the capacity of the material storage cavity 330. Among them, the aerosol generating substrate may refer to a material that can atomize to provide aerosol components under certain conditions, such as one or more of e-liquid, vape juice, tobacco derivatives, or tobacco substitutes.

[0044] The above-mentioned material storage component 300 can at least achieve the following beneficial effects: An outlet 314 communicating with the material storage cavity 330 is provided in either the housing 320 or the air exchange structure 310, facilitating the extraction of the aerosol generating matrix in the material storage cavity 330 and its supply to the atomization component 100. The air exchange structure 310 can be a flexible member, which can elastically deform according to the quantity of the aerosol generating matrix in the material storage cavity 330, dynamically adjusting the capacity of the material storage cavity 330, avoiding excessive negative pressure in the material storage cavity 330, ensuring stable and sufficient oil supply to the atomization component 100, and avoiding the dry burning phenomenon caused by insufficient oil supply. When the aerosol generating matrix in the material storage cavity 330 decreases, the air exchange structure 310 contracts inward, reducing the capacity of the material storage cavity 330; when the aerosol generating matrix in the material storage cavity 330 increases, the air exchange structure 310 expands outward, increasing the capacity of the material storage cavity 330. This dynamic adjustment function enables the material storage component 300 to adapt to different stocks of the aerosol generating matrix, ensuring that the aerosol generating matrix in the material storage cavity 330 can be fully and smoothly supplied from the outlet 314. It can be understood that during the process of the gradual reduction of the aerosol generating matrix in the material storage cavity 330, the elastic deformation of the air exchange structure 310 can balance the pressure in the material storage cavity 330. If the air exchange structure 310 does not contract inward into the material storage cavity 330 to reduce the capacity of the material storage cavity 330, a vacuum negative pressure area will be formed in the material storage cavity 330, affecting the smooth supply of the aerosol generating matrix from the outlet 314 to the outside.

[0045] As Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 shown, in some embodiments, the material storage component 300 further includes a bottom cover 340, the bottom cover 340 is covered on the side of the air exchange structure 310 facing away from the material storage cavity 330 and is connected to the housing 320, and a ventilation hole 342 is provided on the bottom cover 340. The provision of the ventilation hole 342 enables air pressure balance between the material storage cavity 330 and the external environment. When the air exchange structure 310 elastically deforms due to the reduction of the aerosol generating matrix, external air can enter the space between the air exchange structure 310 and the bottom cover 340 through the ventilation hole 342, avoiding problems such as unsmooth oil supply caused by air pressure changes. It can be understood that during the process of the gradual reduction of the aerosol generating matrix in the material storage cavity 330, the air exchange structure 310 contracts into the material storage cavity 330. Without the ventilation hole 342, a vacuum negative pressure area may be formed between the air exchange structure 310 and the bottom cover 340, hindering further deformation of the air exchange structure 310. The design of the ventilation hole 342 effectively avoids this phenomenon, ensuring the normal operation of the air exchange structure 310.

[0046] As Figure 6 and Figure 7As shown, in some embodiments, when the amount of aerosol-generating substrate in the storage chamber 330 increases, the ventilation structure 310 can be elastically deformed according to the stock of the aerosol-generating substrate in the storage chamber 330 to increase the capacity of the storage chamber 330, and the gas on the side of the ventilation structure 310 facing away from the storage chamber 330 can be discharged from the vent 342 to maintain the air pressure balance between the storage chamber 330 and the outside world; when the amount of aerosol-generating substrate in the storage chamber 330 decreases, the ventilation structure 310 can be elastically deformed according to the stock of the aerosol-generating substrate in the storage chamber 330 to reduce the capacity of the storage chamber 330, and the side of the ventilation structure 310 facing away from the storage chamber 330 can receive gas from the outside through the vent 342 to maintain the air pressure balance between the storage chamber 330 and the outside world. When the amount of aerosol-generating substrate in the storage chamber 330 increases, the ventilation structure 310 can expand outward according to the amount of aerosol-generating substrate in the storage chamber 330 to increase the capacity of the storage chamber 330. During this process, gas on the side of the ventilation structure 310 facing away from the storage chamber 330 can be discharged through the vent 342 provided in the bottom cover 340, thereby maintaining the air pressure balance between the storage chamber 330 and the outside world. This design avoids the problem of increased air pressure caused by the increase in aerosol-generating substrate and ensures the stability of the pressure inside the device. When the amount of aerosol-generating substrate in the storage chamber 330 decreases, the ventilation structure 310 can contract inward according to the amount of aerosol-generating substrate in the storage chamber 330 to reduce the capacity of the storage chamber 330. During this process, the side of the ventilation structure 310 facing away from the storage chamber 330 can receive gas from the outside through the vent 342 opened on the bottom cover 340, thereby maintaining the air pressure balance between the storage chamber 330 and the outside world. This design avoids the negative pressure problem caused by the reduction of the aerosol generation matrix and ensures the pressure stability inside the device.

[0047] like Figure 4 and Figure 5 As shown, in some embodiments, the bottom cover 340 is detachably connected to the housing 320. The detachable connection between the bottom cover 340 and the housing 320 not only facilitates assembly during manufacturing, but also allows the bottom cover 340 to be easily removed later, thereby facilitating maintenance of the storage chamber 330, the ventilation structure 310, and other internal components.

[0048] like Figure 4 and Figure 5As shown, in some of the embodiments, a plurality of first latching portions 341 are provided at intervals on the periphery of the bottom cover 340, and a plurality of second latching portions 322 are provided at intervals on the periphery of the mounting opening 321 of the housing 320. The first latching portions 341 and the second latching portions 322 correspond to each other one by one, and the bottom cover 340 is latched with the housing 320 by the cooperation of the plurality of first latching portions 341 and the plurality of second latching portions 322.

[0049] As Figure 4 shown, in some of the embodiments, a limiting convex portion 315 is provided on either one of the bottom cover 340 and the ventilation structure 310, and a limiting concave portion 343 is provided on the other one of the bottom cover 340 and the ventilation structure 310. The limiting convex portion 315 is inserted into the limiting concave portion 343 to limit the relative position between the bottom cover 340 and the ventilation structure 310. The design of the limiting structure makes the assembly of the bottom cover 340 and the ventilation structure 310 simpler and more efficient. The precise positioning between the bottom cover 340 and the ventilation structure 310 can be completed only by aligning the limiting convex portion 315 and inserting it into the limiting concave portion 343, avoiding assembly errors or functional abnormalities caused by position deviation and reducing the assembly difficulty. Through the constraint of the limiting structure, the relative position between the bottom cover 340 and the ventilation structure 310 is fixed, enhancing the stability of the overall structure and preventing loosening or displacement during the operation of the device.

[0050] As Figure 4 shown, in some of the embodiments, a through hole 344 is provided on the bottom cover 340, a discharge pipe 316 is provided on the ventilation structure 310, a discharge port 314 is provided at the end of the discharge pipe 316, and the discharge pipe 316 is communicated with the through hole 344 or the discharge pipe 316 passes through the through hole 344.

[0051] As Figure 6 、 Figure 7 、 Figure 8 and Figure 9As shown, in some of these embodiments, the ventilation structure 310 includes an annular portion 311 and a deformation portion 312 connected to the annular portion 311. The annular portion 311 is hermetically embedded in the mounting opening 321. Further, at least a part of the annular portion 311 is clamped between the bottom cover 340 and the inner wall of the mounting opening 321. A sealing rib 3111 may be formed on the outer circumferential surface of the annular portion 311, and the sealing rib 3111 is used to abut against the inner wall of the mounting opening 321 to achieve sealing. The deformation portion 312 can switch between an extended form and a folded form; when the deformation portion 312 is in the extended form, the capacity of the material storage cavity 330 is the largest; when the deformation portion 312 is in the folded form, the capacity of the material storage cavity 330 is the smallest; during the process of the deformation portion 312 switching from the extended form to the folded form, the deformation portion 312 moves in a direction close to the mounting opening 321; during the process of switching from the folded form to the extended form, the deformation portion 312 moves in a direction away from the mounting opening 321. The annular portion 311 is hermetically embedded in the mounting opening 321, ensuring a tight and leak-free connection between the ventilation structure 310 and the mounting opening 321, and preventing the aerosol-forming matrix in the material storage cavity 330 from leaking out. When the deformation portion 312 switches its form, its movement will not damage the sealing performance, ensuring that the material storage cavity 330 can maintain a reliable sealing performance in different capacity states. The deformation portion 312 can switch between the extended form and the folded form, enabling the capacity of the material storage cavity 330 to be dynamically adjusted between the maximum capacity and the minimum capacity according to actual needs.

[0052] As Figure 6 and Figure 8As shown, in some of these embodiments, a first auxiliary fold 3131 surrounding the annular portion 311 is formed at the junction of the deformable portion 312 and the annular portion 311. During the process of the deformable portion 312 switching from the extended form to the folded form, the first auxiliary fold 3131 can assist the deformable portion 312 to move in the direction close to the mounting opening 321 and fold within the annular portion 311. When the deformable portion 312 switches from the extended form to the folded form, the first auxiliary fold 3131 can assist the deformable portion 312 to move in the direction close to the mounting opening 321, ensuring that the folding process is smoother and more precise. Moreover, the design of the first auxiliary fold 3131 reduces the resistance between the deformable portion 312 and the annular portion 311 during the folding process, making the folding easier and more efficient. The design of the first auxiliary fold 3131 makes the folding movement of the deformable portion 312 more controllable, avoiding jamming or deformation caused by disordered movement, and ensuring the accuracy and reliability of the folding process. The first auxiliary fold 3131 can also reduce the stress concentration of the material during repeated folding when the deformable portion 312 is folded, reducing the risk of material fatigue and damage. With the assistance of the first auxiliary fold 3131, the deformable portion 312 in the folded form can be tightly folded within the annular portion 311, maximizing the capacity of the material storage cavity 330.

[0053] As Figure 6 and Figure 8As shown, in some of these embodiments, the deformation part 312 includes a plurality of folding bodies that are sequentially stacked and connected to the annular part 311. A second auxiliary fold 3132 is formed at the junction of any two adjacent folding bodies. During the process of the deformation part 312 switching from the extended form to the folded form, the second auxiliary fold 3132 can assist the upper folding body to move in the direction close to the mounting opening 321 and fold into the lower folding body. The deformation part 312 is formed by sequentially stacking and connecting a plurality of folding bodies, and each folding body can be independently folded to form a hierarchical folding structure. Each folding body is connected to the adjacent folding body through the second auxiliary fold 3132. During the folding process, the upper folding body can move in the direction close to the mounting opening 321 and fold into the lower folding body, realizing segmented folding to ensure the uniformity and stability of the folding process. When the deformation part 312 switches from the extended form to the folded form, the second auxiliary fold 3132 can assist the upper folding body to move in the direction close to the mounting opening 321, making the folding movement of each folding body more controllable, avoiding jamming or deformation caused by disorderly movement, and enabling the folding body to smoothly transition during the folding process to ensure the accuracy and reliability of the folding process. The design of the second auxiliary fold 3132 reduces the resistance between adjacent folding bodies, making the folding process smoother and more efficient, and avoiding jamming or deformation caused by excessive resistance. The hierarchical folding structure enables the deformation part 312 in the folded form to be tightly folded, maximizing the capacity of the material storage cavity 330.

[0054] As Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, in some of the embodiments, the folding body includes a first folding body 3121 and a second folding body 3122 that are sequentially stacked and connected to the annular portion 311. The first folding body 3121 is connected to the annular portion 311, and a first auxiliary fold 3131 is formed at the junction between the two. A second auxiliary fold 3132 that surrounds the first folding body 3121 is formed at the junction between the second folding body 3122 and the first folding body 3121. During the process of the deformation portion 312 switching from the extended form to the folded form, the second auxiliary fold 3132 can assist the second folding body 3122 to move in the direction close to the installation opening 321 and fold into the first folding body 3121. When the deformation portion 312 switches from the extended form to the folded form, the first auxiliary fold 3131 can guide the first folding body 3121 to move in the direction close to the installation opening 321, and the second auxiliary fold 3132 can assist the second folding body 3122 to move in the direction close to the installation opening 321 and fold into the first folding body 3121, further optimizing the folding effect and ensuring the uniformity and stability of the folding process. This segmented folding makes the folding of the deformation portion 312 more uniform and controllable. The second folding body 3122 is folded into the first folding body 3121, enabling the deformation portion 312 to be tightly folded and maximizing the capacity of the material storage cavity 330.

[0055] As Figure 7 shown, in some of the embodiments, when the deformation portion 312 is in the folded form, the second folding body 3122 is folded into the first folding body 3121 and the cross-sectional profile is M-shaped. The second folding body 3122 can be tightly folded into the first folding body 3121 to form a generally M-shaped folding structure, minimizing the occupied space and increasing the capacity of the material storage cavity 330. In addition, the symmetry of the M-shaped structure makes the stress distribution during the folding process more uniform, avoiding deformation or damage caused by local stress concentration and ensuring the stability of the folded form.

[0056] As Figure 6 , Figure 7 , Figure 8 and Figure 9 shown, in some of the embodiments, a third auxiliary fold 3133 is formed on the side of the second folding body 3122 facing away from the installation opening 321. When the deformation portion 312 is in the folded form, the second folding body 3122 is folded in half along the third auxiliary fold 3133. The third auxiliary fold 3133 provides a clear folding guide for the second folding body 3122, ensuring that it is folded in half along a predetermined direction, making the folding process of the second folding body 3122 more orderly and controllable, avoiding jamming or deformation caused by disorderly folding, and ensuring the smoothness and efficiency of the folding process.

[0057] AsFigure 6 As shown, in some of these embodiments, the thickness of the first auxiliary fold 3131 is less than the thickness of the annular portion 311, the thickness of the first auxiliary fold 3131 is less than the thickness of the folded body, and the thickness of the second auxiliary fold 3132 is less than the thickness of the folded body. The thickness reduction of the first auxiliary fold 3131 makes this area more flexible during the folding process, enabling it to more precisely guide the deformation part 312 to move in the direction close to the installation opening 321, avoiding deviation or jamming during the folding process, improving the accuracy and controllability of folding, and ensuring a smoother folding process. The thickness reduction of the second auxiliary fold 3132 makes this area more flexible during the folding process, enabling it to more precisely guide the folded body to move in the direction close to the installation opening 321, avoiding deviation or jamming during the folding process, improving the accuracy and controllability of folding, and ensuring a smoother folding process.

[0058] In some of these embodiments, the ventilation structure 310 includes at least one of silicone and rubber. Silicone has good flexibility and elasticity, can withstand multiple bends and stretches without being easily deformed, and is suitable for application scenarios that require frequent deformation. Rubber has excellent wear resistance, can withstand long-term use and friction, extends the service life of the ventilation structure 310, and is not easily aged during long-term use, being able to maintain stable performance, and is suitable for application scenarios that require long-term use.

[0059] In some of these embodiments, the housing 320 is a transparent housing 320. The transparent housing 320 makes the internal structure and working state of the device visible, facilitating the user to know the stock of the aerosol generation matrix in real time.

[0060] This application also provides an aerosol generating device 10, which includes an atomization component 100 and the storage component 300 as described in any of the above embodiments.

[0061] The above-mentioned aerosol generating device 10 may be provided with the storage component 300 described in each of the above embodiments. Therefore, the aerosol generating device 10 also has at least the following beneficial effects: An outlet 314 communicating with the storage chamber 330 is formed in either the housing 320 or the air exchange structure 310 of the storage component 300 of the aerosol generating device 10, facilitating the extraction of the aerosol generating substrate in the storage chamber 330 and its supply to the atomization component 100. The air exchange structure 310 can elastically deform according to the quantity of the aerosol generating substrate in the storage chamber 330, dynamically adjusting the capacity of the storage chamber 330, preventing excessive negative pressure in the storage chamber 330, ensuring stable and sufficient oil supply to the atomization component 100, and avoiding the dry burning phenomenon caused by insufficient oil supply. When the aerosol generating substrate in the storage chamber 330 decreases, the air exchange structure 310 contracts inward to reduce the capacity of the storage chamber 330; when the aerosol generating substrate in the storage chamber 330 increases, the air exchange structure 310 expands outward to increase the capacity of the storage chamber 330. This dynamic adjustment function enables the storage component 300 to adapt to different stocks of the aerosol generating substrate, ensuring that the aerosol generating substrate in the storage chamber 330 can be fully and smoothly supplied from the outlet 314. It can be understood that during the gradual reduction of the aerosol generating substrate in the storage chamber 330, the elastic deformation of the air exchange structure 310 can balance the pressure in the storage chamber 330. If the air exchange structure 310 does not contract inward into the storage chamber 330 to reduce the capacity of the storage chamber 330, a vacuum negative pressure area will be formed in the storage chamber 330, affecting the smooth supply of the aerosol generating substrate from the outlet 314 to the outside.

[0062] In some embodiments, the aerosol generating device 10 may further include a suction component 200. The suction component 200 includes a pipeline 210 and a pump body 220 connected to the pipeline 210. One end of the outlet 314 communicates with one end of the pipeline 210, and the other end of the pipeline 210 communicates with the atomization component 100 to supply the aerosol generating substrate to the atomization component 100.

[0063] As Figure 2 shown, in some embodiments, the pump body 220 is disposed between the storage component 300 and the atomization component 100. The atomization component 100 includes an oil storage cotton 110 and an atomization core 120 disposed in the oil storage cotton 110. One end of the pipeline 210 is inserted into the oil storage cotton 110 and can actively supply oil to the oil storage cotton 110 under the drive of the pump body 220.

[0064] In some of these embodiments, the pump body 220 has a first operating state and a second operating state. In the first operating state, the pipeline 210 is blocked by the pump body 220 to stop the pipeline 210 from actively supplying oil to the atomization assembly 100. In the second operating state, the storage chamber 330 can communicate with the atomization assembly 100 through the pipeline 210, and the pipeline 210 can actively supply oil to the atomization assembly 100 under the drive of the pump body 220.

[0065] The pump body 220 may include, but is not limited to, a piezoelectric pump, a peristaltic pump, a diaphragm pump, and a screw pump. Taking the pump body 220 as a peristaltic pump and the pipeline 210 as a flexible pipe as an example, the core components of the peristaltic pump may include a flexible pipe and a roller. The flexible pipe is installed inside the pump body 220, and the roller squeezes the pipeline 210 by rotation to push the liquid flow inside the pipeline 210. By adjusting the extrusion frequency or the roller rotation speed, the peristaltic pump can precisely control the flow rate of the aerosol generation matrix inside the pipeline 210. When the roller rotates, it will sequentially squeeze the flexible pipe to form a closed liquid chamber. As the roller continues to rotate, the squeezed pipeline 210 gradually returns to its original state, generating negative pressure and sucking in the liquid. When the roller rotates to the highest point, it will completely squeeze the pipeline 210 to cut off the path of liquid flow, thereby achieving the blocking of the pipeline 210, which can effectively prevent the aerosol generation matrix on the side close to the atomization assembly 100 from flowing back, ensure the reliability of unidirectional transportation, and avoid the pollution of the aerosol generation matrix in the storage chamber 330. The peristaltic pump realizes the transportation of the aerosol generation matrix by squeezing the flexible pipe, and the aerosol generation matrix only contacts the inner wall of the pipeline 210, avoiding the pollution of the internal parts of the pump body 220.
