Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to a liquid storage component, an atomizer, and an aerosol generating device. Background Technology

[0002] An aerosol generator is an electronic delivery system that uses control circuits and atomizing elements to control its operating status and vapor output for user use.

[0003] In related technologies, aerosol generating devices include an atomizer, which comprises an atomizing component and a liquid storage component. The atomizing component itself may not store the aerosol generating matrix, but can be supplied through the liquid storage component. However, in this type of atomizer, after the liquid storage component and the atomizing component are assembled, either the aerosol generating matrix takes a long time to flow to the atomizing core of the atomizing component, causing the user to wait a long time before inhaling; or the aerosol generating matrix is ​​supplied too quickly, causing leakage at the atomizing core of the atomizing component. Utility Model Content

[0004] In view of this, the embodiments of this application aim to provide a liquid storage component, an atomizer, and an aerosol generating device, which are intended to help shorten the user's waiting time for inhalation, and at the same time, help reduce the risk of leakage at the atomizer core.

[0005] To solve the above problems, the technical solution of this application embodiment is implemented as follows:

[0006] This application provides a liquid storage assembly, including:

[0007] The housing has a mounting cavity and an air outlet channel;

[0008] A liquid storage section is provided in the mounting cavity. The liquid storage section includes a liquid storage element, which adsorbs an aerosol generating matrix. The inner annular surface of the liquid storage element forms an mounting channel. One end of the mounting channel is connected to the gas outlet channel, and the other end of the mounting channel is for inserting an atomizing core. The liquid storage section is configured such that when the atomizing core is inserted into the mounting channel, the aerosol generating matrix adsorbed by the liquid storage element is conducted to the atomizing core through capillary force.

[0009] In some embodiments, the liquid storage section further includes an inner tube and a first sealing ring, the first sealing ring being located at the end of the mounting channel away from the venting channel, and the inner tube having a first position and a second position;

[0010] At the first position, at least a portion of the inner tube is disposed within the installation channel, and one end of the inner tube is sealed in conjunction with the first sealing ring;

[0011] At the second position, the inner tube is separated from the first sealing ring, and at least a portion of the inner ring surface of the liquid reservoir is exposed between the first sealing ring and the inner tube.

[0012] In some embodiments, the liquid storage portion further includes an outer sleeve that covers the liquid storage component, and one end of the outer sleeve is sealed to the first sealing ring.

[0013] In some embodiments, the mounting cavity is open on the side opposite to the air outlet channel, the first sealing ring is located on the open side of the mounting cavity, and a portion of the structure of the first sealing ring is located outside the outer sleeve and abuts against the cavity wall of the mounting cavity; and / or,

[0014] The liquid storage section further includes a second sealing ring, which is located at the end of the outer tube away from the first sealing ring and is sealed to the inner wall of the outer tube. In the second position, the end of the inner tube away from the first sealing ring is sealed to the second sealing ring.

[0015] In some embodiments, at the first position, the distance between the end of the inner tube away from the first sealing ring and the end of the mounting channel near the first sealing ring is a first dimension, and the axial dimension of the mounting channel is a second dimension, wherein the first dimension is not less than half of the second dimension.

[0016] In some embodiments, at the second position, the height of the end of the inner tube away from the first sealing ring is not higher than the height of the bottom end of the air outlet channel.

[0017] This application embodiment provides an atomizer, the atomizer comprising:

[0018] Atomizing components, including the atomizer core;

[0019] In any of the above embodiments of the liquid storage assembly, at least a portion of the atomizing core is disposed within the installation channel, and the aerosol generation matrix adsorbed by the liquid storage component is conducted to the atomizing core through capillary force.

[0020] In some embodiments, the atomizing core includes a liquid guiding element and a heating element. The liquid guiding element is annular and surrounds an atomizing channel. At least a portion of the heating element is disposed in the atomizing channel, and one end of the atomizing channel is connected to the air outlet channel.

[0021] In some embodiments, the atomizing core further includes a core tube surrounding the outer periphery of the liquid guiding component. The core tube has a force transmission surface and a liquid guiding hole. The force transmission surface contacts the liquid storage portion. The aerosol generating matrix in the liquid storage component is conducted to the liquid guiding component through the liquid guiding hole under the action of gross force.

[0022] This application provides an aerosol generating device, the aerosol generating device comprising:

[0023] The atomizer described in any of the above embodiments; and

[0024] The power supply assembly is electrically connected to the atomizing core.

[0025] The liquid storage component of this application embodiment adsorbs the aerosol generation matrix through a liquid storage element. The liquid storage element has a certain liquid-locking ability, which helps to control the liquid supply speed of the liquid storage component. This reduces the probability of leakage at the atomizing core of the atomizer due to excessive liquid supply speed. At the same time, after the atomizing component and the liquid storage component are assembled, the aerosol generation matrix adsorbed by the liquid storage element is conducted to the atomizing core through capillary force. This facilitates the rapid wetting of the atomizing core by the aerosol generation matrix, which helps to shorten the user's waiting time for vaping and reduces the probability of problems such as burnt smell caused by dry burning of the atomizing core. This improves the user experience.

[0026] Furthermore, the liquid storage component in this application embodiment generates a matrix by adsorbing aerosols through the liquid storage element. Since the liquid storage element has a certain liquid-locking ability, it helps to reduce the risk of leakage of the liquid storage component during individual storage or transportation.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects are in an "or" relationship.

[0042] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0043] This application provides an aerosol generating device. Please refer to [link to relevant documentation]. Figures 1 to 3 The aerosol generating device includes a power supply assembly and an atomizer according to any embodiment of this application.

[0044] It should be noted that when the aerosol generating device adopts the atomizer of any embodiment of this application, the aerosol generating device has all the advantages of the atomizer of that embodiment, and the specific advantages are described in detail below.

[0045] It should be noted that the specific type of aerosol generating device in the embodiments of this application is not limited. For example, the aerosol generating device can be a medical nebulizer, an air humidifier, or a nebulizer such as an electronic cigarette.

[0046] The power supply unit is mainly used to supply power to the atomizer and control the opening and closing of the entire aerosol generation device. The atomizer is mainly used to contain the aerosol generation matrix and heat and atomize the aerosol generation matrix after being powered on. The aerosol generation matrix includes, but is not limited to, materials used for medical, wellness, health, and beauty purposes.

[0047] In some embodiments, the atomizer and power supply assembly can be mechanically and electrically connected together axially. Further, the atomizer and power supply assembly can be connected together in a detachable manner using magnetic connections, threaded connections, snap-fit ​​connections, or other similar methods. Both the atomizer and power supply assembly can be replaced or upgraded individually, reducing replacement costs and saving user expenses. Of course, in other embodiments, the atomizer and power supply assembly can also be connected together in a non-detachable manner.

[0048] Furthermore, the atomizer and / or power supply assembly are not limited to being cylindrical; they can also be other shapes such as elliptical or square columns.

[0049] In some embodiments, the atomizer includes a liquid storage component 10 and an atomizing component 20. The liquid storage component 10 is used to contain an aerosol generating matrix, and the atomizing component 20 is electrically connected to a power supply component to heat and atomize the aerosol generating matrix.

[0050] In some embodiments, the liquid storage component 10 and the atomizing component 20 can be assembled using a detachable assembly structure. In this way, after the aerosol generating matrix contained in the liquid storage component 10 is used up, only the liquid storage component 10 needs to be replaced, and the atomizing component 20 does not need to be replaced. This helps to reduce the user's operating costs.

[0051] It is understandable that in this type of atomizer, the atomizer may only use the liquid storage component 10 to contain the aerosol generation matrix, that is, the atomizing component 20 itself may not store the aerosol generation matrix.

[0052] In related technologies, atomizers that do not store the aerosol generation matrix in the atomizing component but supply it through a liquid storage component typically have an open oil tank within the liquid storage component, meaning the aerosol generation matrix is ​​loaded in liquid form within the open oil tank. However, with this structure, if the aerosol generation matrix in the open oil tank directly contacts the atomizer core after assembly, the liquid supply rate will be too fast, leading to leakage at the atomizer core. While a small oil tank on the atomizer component can be used as a transition, allowing the aerosol generation matrix in the open oil tank to first enter the small oil tank after assembly and then supply liquid to the atomizer core, reducing the risk of leakage at the core, the aerosol generation matrix needs to slowly enter the small oil tank before being guided to the atomizer core, resulting in a longer waiting time for the user to vape. In other words, the atomizers in the relevant technologies either have the problem of long waiting time for users to inhale, or have the problem of a high risk of leakage at the atomizer core.

[0053] In view of this, embodiments of this application provide a liquid storage assembly; please refer to [link to relevant documentation]. Figure 5 The liquid storage assembly 10 includes a housing 11 and a liquid storage section 12.

[0054] Furthermore, this application provides an atomizer; please refer to [link to relevant documentation]. Figures 1 to 3 The atomizer includes an atomizing component 20 and a liquid storage component 10 according to any embodiment of this application.

[0055] It should be noted that when the atomizer adopts the liquid storage component 10 of any embodiment of this application, the atomizer has all the advantages of the liquid storage component 10 of that embodiment, and the specific advantages are described in detail below.

[0056] Please see Figure 6 and Figure 7 The atomizing component 20 includes an atomizing core 22, which is electrically connected to the power supply component. The atomizing core 22 can convert electrical energy into other forms of energy and apply them to the aerosol generating matrix, thereby atomizing the aerosol generating matrix and generating aerosol.

[0057] The atomizing assembly 20 also includes an atomizing base 21, on which the atomizing core 22 is disposed. That is, the atomizing base 21 provides a mounting base for the atomizing core 22.

[0058] The specific structure of the atomizing core 22 is not limited.

[0059] In some embodiments, please refer to Figure 6 and Figure 7 The atomizing core 22 includes a liquid guiding component 222 and a heating component 223, with the liquid guiding component 222 surrounding the outer periphery of the heating component 223. The heating component 223 is electrically connected to a power supply assembly, and converts electrical energy into other forms of energy that act on the aerosol generating matrix to heat and atomize the aerosol generating matrix, thereby generating aerosol. The liquid guiding component 222 transmits or delivers the aerosol generating matrix to the heating component 223, for example, through capillary action or other forces. The material of the liquid guiding component 222 includes, but is not limited to, non-woven fabric, cotton, ceramic, glass, quartz, or fiber.

[0060] The specific method by which the heating element 223 heats the aerosol to generate the matrix is ​​not limited. For example, it can be resistance heating, electromagnetic induction heating, infrared heating, microwave heating, laser heating, air heating, electric field heating, carbon source heating, plasma heating, etc.

[0061] Specifically, the heating element 223 that uses resistance heating is called the heating element. The heating element can convert electrical energy into heat energy, thereby heating the aerosol generation matrix to generate aerosols.

[0062] There are no restrictions on the specific type of heating element. For example, it can be a heating needle, heating film, heating mesh, heating plate, or heating wire, etc.

[0063] In some embodiments, please refer to Figure 3 and Figure 4The liquid guiding component 222 is annular and surrounds an atomizing channel 222a. At least a portion of the heating component 223 is disposed within the atomizing channel 222a, and one end of the atomizing channel 222a is connected to the air outlet channel 11b. In this way, aerosol is generated within the atomizing channel 222a, which can then directly enter the air outlet channel 11b and flow out through the air outlet channel 11b for user use.

[0064] In some embodiments, please refer to Figure 6 and Figure 7 The atomizing core 22 also includes a core tube 221, which surrounds the outer periphery of the liquid guiding component 222. The core tube 221 is provided with a liquid guiding hole 221a. The aerosol generating matrix on the outer periphery of the core tube 221 can wet the liquid guiding component 222 through the liquid guiding hole 221a, thereby guiding it to the heating component 223.

[0065] It is understandable that by setting the core tube 221, the overall structural strength of the atomizing core 22 can be improved, and the core tube 221 can protect the liquid guiding component 222 and the heating component 223.

[0066] The specific material of the core tube 221 is not limited. For example, the core tube 221 can be made of various types of food-grade materials such as stainless steel.

[0067] The housing 11 is provided with an installation cavity 11a and an air outlet channel 11b. The liquid storage part 12 is provided in the installation cavity 11a. The liquid storage part 12 includes a liquid storage element 121, which adsorbs an aerosol generating matrix. The inner annular surface of the liquid storage element 121 surrounds the installation channel 121a. One end of the installation channel 121a is connected to the air outlet channel 11b, and the other end of the installation channel 121a is for the atomizing core 22 to be inserted. The liquid storage part 12 is configured such that when the atomizing core 22 is inserted into the installation channel 121a, the aerosol generating matrix adsorbed by the liquid storage element 121 is conducted to the atomizing core through capillary force.

[0068] Specifically, the inner annular surface of the liquid reservoir 121 is in direct contact with the atomizing core 22. That is, after the liquid reservoir assembly 10 and the atomizing assembly 20 are assembled, at least a portion of the atomizing core 22 is disposed within the mounting channel 121a and in direct contact with the inner annular surface of the liquid reservoir 121. In this way, the aerosol-generating matrix adsorbed by the liquid reservoir 121 directly contacts the atomizing core 22, thereby directly wetting the atomizing core 22. This helps to further improve the wetting rate of the atomizing core 22, thus shortening the user's waiting time for inhalation.

[0069] The outer wall of the housing 11 forms the outer wall surface of the liquid storage assembly 10. The housing 11 is the mounting base component of the liquid storage assembly 10 and is used for mounting other components of the liquid storage assembly 10 (such as the liquid storage section 12).

[0070] The specific shape and size of the mounting cavity 11a are not limited, as long as they can accommodate the installation of the liquid storage section 12.

[0071] The aerosol generated at the atomizing core 22 is located within the area enclosed by the installation channel 121a, thus allowing it to enter the air outlet channel 11b and flow out through the air outlet channel 11b for user use.

[0072] The specific material of the liquid reservoir 121 is not limited. For example, the liquid reservoir 121 may be made of an absorbent material that can adsorb a certain amount of aerosol to form a matrix. Specifically, these absorbent materials include one or more of polyethylene glycol terephthalate (PET) and nylon (PA), etc.

[0073] The liquid storage device 121 can adsorb a certain amount of aerosol to generate a matrix, and the liquid storage device 121 has a certain liquid-locking performance. This helps to reduce the liquid supply speed to the atomizing core 22, thereby reducing the probability of leakage problems at the atomizing core 22.

[0074] The liquid guiding speed of the liquid guiding component 222 is faster than the liquid supply speed of the liquid storage component 121.

[0075] After the liquid storage component 10 and the atomizing component 20 are assembled, the aerosol generation matrix adsorbed by the liquid storage component 121 is conducted to the atomizing core 22 through capillary force (specifically, the atomizing core 22 can be in direct contact with the liquid storage component 121, and the aerosol generation matrix adsorbed by the liquid storage component 121 can be in direct contact with the liquid guide component 222 through the liquid guide hole 221a). In this way, the liquid guide component 222 can be wetted relatively quickly, thereby guiding the flow to the heating element 223. This helps to reduce the user's waiting time for inhalation, helps to improve the problem of dry burning of the heating element 223 due to slow liquid guide speed, helps to reduce the probability of burnt smell and other problems, and helps to improve the user's user experience.

[0076] In summary, the liquid storage component 10 of this application embodiment adsorbs the aerosol generation matrix through the liquid storage element 121. The liquid storage element 121 has a certain liquid-locking ability, which helps to control the liquid supply speed of the liquid storage component 10. This reduces the probability of leakage at the atomizing core 22 of the atomizer due to excessive liquid supply speed. At the same time, the aerosol generation matrix adsorbed by the liquid storage element 121 is conducted to the atomizing core 22 through capillary force. In this way, the aerosol generation matrix can quickly wet the atomizing core 22, which helps to shorten the user's waiting time for inhalation and reduces the probability of burnt smell and other problems caused by dry burning of the atomizing core 22. This improves the user's experience.

[0077] Furthermore, the liquid storage component 10 of this application embodiment generates a matrix by adsorbing aerosols through the liquid storage element 121. Since the liquid storage element 121 has a certain liquid-locking ability, it helps to reduce the risk of leakage of the liquid storage component 10 during individual storage or transportation.

[0078] In some embodiments, please refer to Figure 5 The liquid storage section 12 also includes an inner tube 123 and a first sealing ring 124. The first sealing ring 124 is located at the end of the installation channel 121a away from the gas outlet channel 11b. The inner tube 123 has a first position and a second position.

[0079] The specific material of the first sealing ring 124 is not limited. For example, it can be a food-grade material such as silicone.

[0080] In the first position, at least a portion of the inner tube 123 is disposed within the installation channel 121a, and one end of the inner tube 123 is sealed to the first sealing ring 124. Thus, when the liquid storage assembly 10 is not assembled with the atomizing assembly 20, the aerosol-generating matrix adsorbed by the liquid storage component 121 will not leak out between the inner tube 123 and the first sealing ring 124, thereby reducing the risk of leakage from the liquid storage assembly 10 and facilitating its independent transportation or storage.

[0081] It should be noted that there are no restrictions on the specific method by which the inner tube 123 and the first sealing ring 124 achieve a sealing fit.

[0082] For example, please refer to Figure 5 One end of the inner tube 123 is inserted into the inner ring surface of the first sealing ring 124. In this way, the inner tube 123 can be installed on the first sealing ring 124 relatively stably, and a relatively stable sealing fit with the first sealing ring 124 can also be achieved.

[0083] In the second position, the inner tube 123 is separated from the first sealing ring 124, and at least a portion of the inner ring surface of the liquid storage element 121 is exposed between the first sealing ring 124 and the inner tube 121. Thus, after the atomizing core 22 is inserted into the installation channel 121a, the aerosol generation matrix adsorbed by the liquid storage element 121 can flow out from the gap between the inner tube 121 and the first sealing ring 124, thereby wetting the atomizing core 22.

[0084] In this embodiment, when injecting liquid into the liquid storage component 121, the liquid storage component 121, the inner tube 123 and the first sealing ring 124 can be assembled into a whole, and then the whole can be placed into the mounting cavity 11a, with the first sealing ring 124 located at the bottom of the liquid storage part.

[0085] At this point, the outer wall of the first sealing ring 124 can be sealed to the side wall of the mounting cavity 11a, and the top side of the mounting cavity 11a can be left open. This allows liquid to be injected into the reservoir 121 from top to bottom. The side wall of the mounting cavity 11a limits the outer ring surface of the reservoir 121, and the inner tube 123 contacts the inner ring surface of the reservoir 121, thus facilitating a more stable adsorption of the aerosol generation matrix by the reservoir 121.

[0086] It should be noted that in the embodiments of this application, the orientations and directions such as "upper," "lower," "top," and "bottom" should be understood based on the height direction of the aerosol generating device under normal operating conditions. Specifically, the height direction is... Figure 3 and Figure 5 The direction indicated by H in the middle.

[0087] Understandably, since the first sealing ring 124 is located at the bottom of the liquid storage section 12 during liquid injection, the amount of aerosol matrix adsorbed by the liquid storage component 121 in the area near the end of the first sealing ring 124 is relatively large, and the first sealing ring 124 can reduce the leakage problem of the liquid storage component 10.

[0088] In this embodiment, the first sealing ring 124 is located at the bottom of the liquid storage component 10, meaning that the aerosol generation matrix in the area where the liquid storage component 121 directly contacts the atomizing core 22 has a greater adsorption capacity. After the liquid storage component 10 and the atomizing component 20 are assembled, sufficient aerosol generation matrix can be used to wet the liquid guiding component 222 within a short time, thereby supplying liquid to the heating component 223. This helps to shorten the time the user waits for suction immediately after the liquid storage component 10 and the atomizing component 20 are assembled.

[0089] In addition, when the liquid storage assembly 10 is stored or transported separately, the bottom area of ​​the liquid storage component 121 can be sealed by the inner tube 123 and the first sealing ring 124, which helps to reduce the probability of the aerosol generation matrix leaking from the liquid storage section 12 under the action of gravity.

[0090] In some embodiments, please refer to Figures 3 to 5 The inner tube 123 is movably disposed along the axial direction of the mounting channel 121a, and can move from a first position to a second position. In this way, the structure of the inner tube 123 is relatively simple and easy to manufacture.

[0091] In some embodiments, please refer to Figures 3 to 5 The liquid storage section 12 also includes an outer sleeve 122, which is fitted onto the liquid storage component 121, and one end of the outer sleeve 122 is sealed to the first sealing ring 124.

[0092] Specifically, the inner wall of one end of the outer sleeve 122 can be sealed to the first sealing ring 124.

[0093] Here, the liquid reservoir 121 can be filled with liquid outside the mounting cavity 11a.

[0094] During assembly, the liquid storage unit 12 can be assembled by inserting the inner tube 123 into the first sealing ring 124 to form a whole, and then assembling it with the whole consisting of the outer tube 122 and the liquid storage component 121. Alternatively, the liquid storage component 121 and the outer tube 122 (installation order is not limited) can be installed sequentially onto the whole consisting of the inner tube 123 and the first sealing ring 124. This assembly method is relatively simple and helps to improve the assembly efficiency of the liquid storage unit 12.

[0095] When filling the liquid storage component 121, the end where the first sealing ring 124 is located is taken as the bottom of the liquid storage section 12. The inner tube 123, the first sealing ring 124, and the outer tube 122 roughly form an annular groove, and the liquid storage component 121 is located in this annular groove. In this way, when filling the liquid storage component 121, it is beneficial to improve the problem of the aerosol generating matrix flowing out of the liquid storage section 12 due to the influence of pressure and gravity. It can be understood that after assembling the liquid storage component 121, the outer tube 122, the inner tube 123, and the first sealing ring 124, the first sealing ring 124 can be placed at the bottom. At this time, the liquid storage component 121 is then filled with liquid. After the liquid storage component 121 is filled with liquid, the entire liquid storage section 12 is then placed into the mounting cavity 11a.

[0096] It is understood that the liquid storage component 121 in this embodiment can be filled with liquid outside the mounting cavity 11a. The liquid storage component 121 is less restricted in terms of operating space when filling with liquid, which makes it easier to operate and thus helps to improve the production efficiency of the liquid storage component 10.

[0097] Both the outer tube 122 and the inner tube 123 can be made of materials with a certain degree of hardness. Since both the outer tube 122 and the inner tube 123 are in contact with the liquid storage component 121, both the outer tube 122 and the inner tube 123 can be made of various types of food-grade materials such as stainless steel.

[0098] In some embodiments, please refer to Figure 5 In the first position, the distance between the end of the inner tube 123 away from the first sealing ring 124 and the end of the mounting channel 121a close to the first sealing ring 124 is the first dimension, and the axial dimension of the mounting channel 121a is the second dimension. The first dimension is not less than half of the second dimension.

[0099] For example, the first size is as follows Figure 5 As shown in d1.

[0100] Thus, the fixed length of the inner tube 123 or the whole formed by the inner tube 123 and the first sealing ring 124 to the liquid storage component 121 is not less than half of the axial length of the liquid storage component 121.

[0101] It is understandable that after the liquid reservoir 121 is fixed in at least half of its axial direction, the radial expansion of the entire reservoir 121a will not be too large. This helps to further reduce the probability of leakage during the liquid injection process of the liquid reservoir 12.

[0102] In some embodiments, please refer to Figures 3 to 5 The mounting cavity 11a is open on the side opposite to the air outlet channel 11b. The first sealing ring 124 is located on the open side of the mounting cavity 11a. Part of the structure of the first sealing ring 124 is located outside the outer sleeve 122 and abuts against the cavity wall of the mounting cavity 11a.

[0103] For example, please refer to Figure 5 The bottom side of the mounting cavity 11a is open. This facilitates the assembly of the atomizing component 20 with the liquid storage component 10 from the bottom side of the mounting cavity 11a.

[0104] The air outlet channel 11b is located on the top side of the housing 11, and the axial direction of the air outlet channel 11b is nearly parallel to the height direction of the aerosol generating device.

[0105] The liquid storage unit 12 can be inserted into the mounting cavity 11a from the open side of the mounting cavity 11a. Since the first sealing ring 124 abuts against the cavity wall of the mounting cavity 11a, no other components are needed to connect the housing 11 and the liquid storage unit 12.

[0106] In this embodiment, the connection between the liquid storage section 12 and the housing 11 is achieved through the interference fit between the first sealing ring 124 and the housing 11, which helps to improve the assembly efficiency of the liquid storage assembly 10.

[0107] In some embodiments, please refer to Figures 3 to 5 The liquid storage section 12 also includes a second sealing ring 125, which is located at the end of the outer sleeve 122 away from the first sealing ring 124 and is sealed to the inner wall of the outer sleeve 122.

[0108] Specifically, after the liquid storage component 121 is filled with liquid, the second sealing ring 125 and the liquid suction component 126 (described below) are installed in sequence.

[0109] By providing a second sealing ring 125, the probability of leakage at the end of the liquid storage section 12 that is far from the first sealing ring 124 is reduced, thereby further reducing the risk of leakage of the liquid storage section 12.

[0110] In the second position, the end of the inner tube 123 away from the first sealing ring 124 is sealed with the second sealing ring 125.

[0111] Specifically, please refer to Figure 3In the second position, the end of the inner tube 123 away from the first sealing ring 124 is inserted into the inner ring surface of the second sealing ring 125.

[0112] In this way, the aerosol generating matrix guided by the liquid guiding element 222 can only flow to the atomizing core 22 through the area between the end of the inner tube 123 near the first sealing ring 124 and the first sealing ring 124. This allows the aerosol generating matrix to be heated and atomized in a timely manner to generate aerosols. Simultaneously, it also helps to control the liquid supply of the aerosol generating matrix, thereby further reducing the risk of leakage.

[0113] In some embodiments, please refer to Figure 3 The second sealing ring 125 abuts against the cavity wall of the mounting cavity 11a. Specifically, the two can be an interference fit.

[0114] In this way, both ends of the liquid storage section 12 can be connected to the housing 11 relatively stably, which helps to improve the connection stability and reliability between the liquid storage section 12 and the housing 11.

[0115] In some embodiments, please refer to Figure 3 and Figure 5 The liquid storage section 12 also includes a liquid suction member 126, which is located at one end of the air outlet channel 11b near the second sealing ring 125.

[0116] When the user stops pumping, some unused aerosol will remain in the exhaust channel 11b. This aerosol will condense to form condensate, which may flow to the outside of the power supply components or aerosol generating device under gravity. Flowing to the power supply components may affect their reliability, while flowing to the outside of the aerosol generating device may contaminate the user's skin or clothing, resulting in a poor user experience.

[0117] In this embodiment, the liquid suction member 126 can effectively absorb condensate, thereby improving a series of problems caused by condensate.

[0118] In some embodiments, please refer to Figure 5 The liquid storage assembly 10 also includes a first plug 13 and a second plug 14. The first plug 13 is detachably disposed on the liquid storage part 12 and seals the end of the installation channel 121a away from the gas outlet channel 11b. The second plug 14 is detachably disposed on the housing 11 and seals the gas outlet channel 11b.

[0119] When the liquid storage assembly 10 is not assembled with the atomizing assembly 20, the first plug 13 and the second plug 14 can isolate the air outlet channel 11b and the installation channel 121a from the outside of the liquid storage assembly 10. This helps to reduce the contamination problem caused by external debris, stains, etc. entering the air outlet channel 11b and the installation channel 121a when the liquid storage assembly 10 is stored or transported alone, and also helps to reduce the risk of leakage of the liquid storage assembly 10.

[0120] Understandably, when assembling the atomizing component 20 and the liquid storage component 10, removing the first plug 13 establishes a connection between the installation channel 121a and the outside of the liquid storage component 10. This allows the atomizing core 22 to be inserted through this end of the installation channel 121a, thus enabling the installation of the atomizing component 20 and the liquid storage component 10. Removing the second plug 14 allows the inhalation of aerosols via the air outlet channel 11b.

[0121] In some embodiments, please refer to Figure 3 , Figure 4 , Figure 6 and Figure 7 During the insertion of the atomizing core 22 through one end of the installation channel 121a, the inner tube 123 is pushed from the first position to the second position.

[0122] In this way, when assembling the atomizing component 20 and the liquid storage component 10, the inner tube 123 can be moved from the first position to the second position simultaneously. The user no longer needs to perform the step of moving the inner tube 123 separately. This simplifies the operation steps when the user replaces the liquid storage component 10, thereby improving the assembly efficiency of the atomizing component 20 and the liquid storage component 10 and enhancing the user's experience.

[0123] It should be noted that the specific structure by which the atomizing core 22 drives the inner tube 123 is not limited.

[0124] In some embodiments, during the insertion of the atomizing core 22 into the installation channel 121a, the end face of the atomizing core 22 contacts the end face of the inner tube 123, thereby pushing the inner tube 123 to move.

[0125] In other embodiments, please refer to Figure 3 , Figure 4 , Figure 6 and Figure 7 The atomizing core 22 is provided with a force transmission surface 221b. Specifically, the core tube 221 may be provided with a force transmission surface 221b. The force transmission surface 221b contacts the liquid storage part 12. During the process of inserting the atomizing core 22 into the installation channel 121a, the force transmission surface 221b abuts against the end face of the inner tube 123 and pushes the inner tube 123 to move.

[0126] Specifically, the force transmission surface 221b is a stepped surface on the periphery of the core tube 221.

[0127] During the insertion of the atomizing coil 22 into the installation channel 121a, the insertion end of the atomizing coil 22 enters the inner tube 123 until the force transmission surface 221b contacts the end face of the inner tube 123. The force transmission surface 221b then pushes the inner tube 123 to move. The portion of the atomizing coil 22 inserted into the inner tube 123 forms a radial fit with the inner tube 123, which helps reduce the probability of the inner tube 123 wobbling along its radial direction. This, in turn, improves the stability and reliability of the inner tube 123 when moving from the first position to the second position.

[0128] In some embodiments, please refer to Figure 3 , Figure 4 , Figure 6 and Figure 7 In the second position, the height of the end of the inner tube 123 away from the first sealing ring 124 is not higher than the height of the bottom end of the air outlet channel 11b.

[0129] Specifically, please refer to Figure 3 , Figure 4 , Figure 6 and Figure 7 The inner wall of the housing 11 includes a structural surface 11c. One end of the air outlet channel 11b near the first sealing ring 124 passes through the structural surface 11c. The axial dimension of the inner tube 123 is less than or equal to the distance between the force transmission surface 221b and the structural surface 11c.

[0130] Specifically, the spacing between the force-transmitting surface 221b and the structural surface 11c is as follows: Figure 3 As shown in d2.

[0131] In this way, after the atomizing component 20 and the liquid storage component 10 are assembled, the end of the inner tube 123 near the air outlet channel 11b will at most reach the position that contacts the end face of the air outlet channel 11b, and will not reach the position that needs to enter the air outlet channel 11b.

[0132] This helps to avoid the problem of the inner tube 123 getting stuck due to interference between the end of the inner tube 123 away from the force transmission surface 221b and the end face of the air outlet channel 11b during the process of moving the inner tube 123 to the second position.

[0133] In some embodiments, please refer to Figure 3 , Figure 4 , Figure 6 and Figure 7 In the second position, the two opposite ends of the inner tube 123 abut against the force transmission surface 221b and the structural surface 11c, respectively. This helps to improve the stability of the inner tube 123.
