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. Based on the use of a detachable assembly structure for the atomizing component and liquid storage component, after replacing the liquid storage component, the user needs to wait a considerable amount of time for the aerosol generating matrix within the liquid storage component to reach the atomizing core of the atomizing component. In other words, the liquid supply speed of the liquid storage component is slow, which is inconvenient for users. 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 facilitate faster liquid supply from the liquid storage component to the atomizer component, so as to facilitate user use.

[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 shell has an internal cavity;

[0008] A movable component, which defines a first liquid storage chamber with the cavity wall of the inner cavity, the first liquid storage chamber being used to store an aerosol generation matrix, the movable component including a main body and a sealing part, the main body having a mounting hole, the sealing part closing the mounting hole, the sealing part being configured to release the seal under external force, and the main body being movably disposed along the axial direction of the mounting hole.

[0009] In some embodiments, the housing includes an outer shell and a guide post, the outer shell surrounding the periphery of the guide post and defining the inner cavity therebetween, the main body being annular, and the inner annular surface of the main body being fitted onto the guide post.

[0010] In some embodiments, the inner annular surface of the main body is sealed to the guide post, and the outer annular surface of the main body is sealed to the inner sidewall of the outer casing.

[0011] In some embodiments, the main body includes a first component and a second component, the second component having a higher hardness than the first component, and the first component sealingly fitting with the cavity wall of the inner cavity.

[0012] This application embodiment provides an atomizer, the atomizer comprising:

[0013] The liquid storage assembly described in any of the above embodiments; and

[0014] An atomizing assembly includes an atomizing base and an atomizing core disposed in the atomizing base. The atomizing base includes a lower liquid column, which surrounds and forms a lower liquid channel. The lower liquid column passes through the mounting hole, and one end of the lower liquid channel is connected to the first liquid storage tank, while the other end is connected to the liquid of the atomizing core.

[0015] During the process of the lower liquid column extending into the first liquid storage chamber, the atomizing seat pushes the main body to move in a direction that reduces the volume of the first liquid storage chamber.

[0016] In some embodiments, the atomizing seat further includes a body and a support, the body being disposed on the side of the main body away from the first liquid storage chamber, and one end of the lower liquid column and one end of the support being disposed on the body;

[0017] As the liquid column extends into the first liquid storage tank, the other end of the support body supports the main body and pushes the main body to move.

[0018] In some embodiments, the number of supports is at least three, and the at least three supports are evenly spaced along the circumference of the body.

[0019] In some embodiments, the support includes a first support that is fitted to the peripheral sidewall of the lower liquid column; and / or,

[0020] The support body includes a second support body, which is spaced apart from the lower liquid column along the circumference of the main body.

[0021] In some embodiments, as the liquid channel extends into the first liquid storage chamber, the area traversed by the side of the main body away from the first liquid storage chamber is a compression chamber. The atomizing seat also has a second liquid storage chamber, and the main body constitutes at least a portion of the chamber wall of the second liquid storage chamber. The atomizing core includes a liquid guiding element and a heating element. The liquid guiding element surrounds the outer periphery of the heating element. The volume of the compression chamber is greater than the volume of the second liquid storage chamber, and less than or equal to the sum of the capacity of the liquid guiding element and the volume of the second liquid storage chamber.

[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] A power supply assembly, which is electrically connected to the atomizer.

[0025] The liquid storage component of this application embodiment, by moving the main body along the axial direction of the mounting hole, can reduce the volume of the first liquid storage chamber during the movement, thereby compressing the aerosol generating matrix within the first liquid storage chamber. For example, when the first liquid storage chamber is full of aerosol generating matrix, during the movement of the main body in the direction of reducing the volume of the first liquid storage chamber, at least an amount of aerosol generating matrix equal to the reduction in the volume of the first liquid storage chamber leaves the first liquid storage chamber. The aerosol generating matrix can be supplied with liquid under external force, which helps to improve the liquid supply speed of the liquid storage component. After the liquid storage component and the atomizing component are assembled, it helps to shorten the user's waiting time for inhalation, reduce the probability of the atomizing core burning dry and producing a burnt smell during inhalation, thereby improving the user experience and making it easier for users to use.

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.

[0041] In the description of the embodiments of this application, unless otherwise expressly specified and limited, technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0043] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0044] This application provides an aerosol generating device. Please refer to [link to relevant documentation]. Figures 1 to 5 The aerosol generating device includes a power supply assembly and an atomizer according to any embodiment of this application.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] In related technologies, based on atomizing components and liquid storage components with detachable assembly structures, after the liquid storage component is assembled with the atomizing component, the aerosol generating matrix contained in the liquid storage component can only gradually flow to the atomizing component under the action of gravity. The aerosol generating matrix leaves the liquid storage component relatively slowly. Therefore, users need to wait for a period of time before they can vape; otherwise, the atomizing coil may burn dry, resulting in a burnt smell. In other words, with liquid storage components in related technologies, the user waiting time for vaping is long, leading to a poor user experience and inconvenience for users.

[0054] In view of this, embodiments of this application provide a liquid storage assembly; please refer to [link to relevant documentation]. Figures 1 to 3 The liquid storage assembly 10 includes a housing 11 and a moving assembly.

[0055] Furthermore, this application provides an atomizer; please refer to [link to relevant documentation]. Figure 4 and Figure 5 The atomizer includes an atomizing component 20 and a liquid storage component 10 according to any embodiment of this application.

[0056] 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.

[0057] The housing 11 has an inner cavity 11a, and the moving component and the cavity wall of the inner cavity 11a define a first liquid storage chamber 10a. The first liquid storage chamber 10a is used to store the aerosol generation matrix.

[0058] Specifically, the movable component may be located in the inner cavity 11a.

[0059] In some embodiments, one side of the cavity 11a is open, thereby facilitating the placement of the movable component within the cavity 11a.

[0060] For example, please refer to Figure 2 and Figure 3 The bottom side of the inner cavity 11a is open.

[0061] 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 2 , Figure 7 and Figure 9 The direction indicated by H in the middle.

[0062] The specific material of the housing 11 is not limited. For example, the housing 11 can be made of a transparent or translucent material, so that the user can easily observe the liquid level of the aerosol generating matrix in the first liquid storage chamber 10a through the housing 11, thereby making it easy for the user to confirm the remaining amount of the aerosol generating matrix, and thus making it easy for the user to confirm whether a new liquid storage component 10 needs to be replaced.

[0063] The atomizing assembly 20 includes an atomizing base 21 and an atomizing core 22 disposed in the atomizing base 21.

[0064] The specific structure of the atomizing core 22 is not limited.

[0065] In some embodiments, please refer to Figure 7 and Figure 8 The atomizing core 22 includes a liquid guiding component 221 and a heating component 222. The heating component 222 is electrically connected to the power supply component. The heating component 222 converts electrical energy into other forms of energy and acts on the aerosol generating matrix to heat and atomize the aerosol generating matrix, thereby generating aerosol. The liquid guiding component 221 transmits or delivers the aerosol generating matrix to the heating component 222, for example, through capillary action or other forces. The material of the liquid guiding component 221 includes, but is not limited to, cotton, ceramic, glass, quartz, or fiber.

[0066] The specific method by which the heating element 222 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.

[0067] Specifically, the heating element 222 that uses resistance heating is called a heating element. The heating element can convert electrical energy into heat energy, thereby heating the aerosol generation matrix to generate aerosols.

[0068] 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.

[0069] The movable component includes a main body 12 and a sealing part 13. The main body 12 is provided with a mounting hole 12a, and the sealing part 13 closes the mounting hole 12a. The sealing part 13 is configured to release the seal under the action of an external force.

[0070] Thus, with the sealing part 13 closing the mounting hole 12a, the aerosol generating matrix in the first liquid storage tank 10a will essentially not flow out from the mounting hole 12a. After the sealing part 13 is released, the aerosol generating matrix in the first liquid storage tank 10a can flow out through the mounting hole 12a for liquid supply, or it can be supplied through a structure provided in the mounting hole 12a (such as the liquid channel 213a of the liquid column 213 mentioned below).

[0071] The sealing part 13 closes the mounting hole 12a, and the specific structure of the sealing part 13 to release the seal under the action of external force is not limited.

[0072] For example, one end of the mounting hole 12a passes through the side of the main body 12 away from the first liquid storage tank 10a, and the other end is isolated from the first liquid storage tank 10a by the sealing part 13. The sealing part 13 is configured to be pierced or separated from the main body 12 under the action of external force.

[0073] The atomizing base 21 includes a lower liquid column 213, which forms a lower liquid channel 213a. After the atomizing assembly 20 and the liquid storage assembly 10 are assembled, the lower liquid column 123 passes through the mounting hole 12a, one end of the lower liquid channel 213a is connected to the first liquid storage chamber 10a, and the other end is connected to the liquid in the atomizing core 22.

[0074] The liquid connection between the liquid channel 213a and the atomizing core 22 means that the aerosol generation matrix in the liquid channel 213a can be guided to the atomizing core 22.

[0075] It is understandable that when the liquid storage component 10 is not assembled with the atomizing component 20, the sealing part 13 seals the end of the mounting hole 12a near the first liquid storage chamber 10a. This helps to improve the problem of the aerosol generating matrix stored in the first liquid storage chamber 10a leaking out from the mounting hole 12a. The liquid storage component 10 can realize the function of storing the aerosol generating matrix independently. The aerosol generating matrix can be stably contained in the first liquid storage chamber 10a, thereby facilitating the transportation and storage of the liquid storage component 10.

[0076] During the assembly of the atomizing component 20 and the liquid storage component 10, the lower liquid column 213 passes through the mounting hole 12a and can puncture the sealing part 13 or separate the sealing part 13 from the main body 12. In this way, the aerosol generating matrix in the first liquid storage chamber 10a can flow into the second liquid storage chamber 21a through the lower liquid channel 213a.

[0077] The specific structure of the sealing part 13 is not limited.

[0078] In some embodiments, please refer to Figure 2 and Figure 3 The sealing part 13 can be integrally formed into a sealing membrane by the main body 12. In this way, when the liquid column 213 passes through the mounting hole 12a, it can pierce the sealing membrane, thereby making the liquid channel 213a connected to the first liquid storage tank 10a.

[0079] In other embodiments, the sealing part 13 can be a sealing plug, that is, the sealing part 13 and the main body 12 can be a separate structure, with the sealing plug disposed on the main body 12 to seal one end of the mounting hole 12a. In this way, as the liquid column 213 passes through the mounting hole 12a, it can push open the sealing plug and detach it from the main body 12, thereby allowing the liquid channel 123a to communicate with the first liquid storage tank 10a.

[0080] The specific material of the sealing part 13 is not limited. For example, the material of the sealing part 13 can be food-grade materials such as silicone.

[0081] The main body 12 is movable along the axial direction of the mounting hole 12a. It is understood that the volume of the first liquid storage chamber 10a will change during the movement of the main body 12 along the axial direction of the mounting hole 12a.

[0082] Specifically, the main body 12 has a first position and a second position.

[0083] Please see Figure 2 and Figure 3 With the liquid storage component 10 not assembled with the atomizing component 20, the main body 12 is in the first position; please refer to Figure 7 and Figure 8 After the liquid storage component 10 is assembled with the atomizing component 20, the main body 12 is in the second position.

[0084] When the main body 12 is in the second position, the volume of the first liquid storage chamber 10a is smaller than the volume of the first liquid storage chamber 10a when the main body 12 is in the first position. In this way, during the transition from the first position to the second position, the aerosol generating matrix within the first liquid storage chamber 10a can be compressed. At this time, the aerosol generating matrix is ​​subjected to the compressive force transmitted from the main body 12, and this force, combined with the gravity of the aerosol generating matrix itself, accelerates the speed at which the aerosol generating matrix leaves the first liquid storage chamber 10a. This helps to reduce the user's waiting time for aspiration.

[0085] In summary, the liquid storage component 10 of this application embodiment, by moving the main body 12 axially along the mounting hole 12a, can reduce the volume of the first liquid storage chamber 10a during the movement, thereby compressing the aerosol generating matrix within the first liquid storage chamber 10a. For example, when the first liquid storage chamber 10a is full of aerosol generating matrix, during the movement of the main body 12 in the direction of reducing the volume of the first liquid storage chamber 10a, at least an amount of aerosol generating matrix equal to the reduction in the volume of the first liquid storage chamber 10a will leave the first liquid storage chamber 10a. The aerosol generating matrix can be supplied with liquid under external force, which is beneficial to improving the liquid supply speed of the liquid storage component 10. After the liquid storage component 10 and the atomizing component 20 are assembled, it is beneficial to shorten the user's waiting time for inhalation, reduce the probability of the atomizing core 22 burning dry and producing a burnt smell during inhalation, thereby improving the user experience and making it easier for the user to use.

[0086] In some embodiments, as the liquid channel 213a extends into the first liquid storage chamber 10a, the atomizing seat 21 pushes the main body 12 to move in a direction that reduces the volume of the first liquid storage chamber 10a.

[0087] In other words, during the assembly of the liquid storage component 10 and the atomizing component 20, the atomizing seat 21 can push the main body 12 from the first position to the second position.

[0088] In this way, the operation of moving the main body 12 from the first position to the second position does not need to be performed separately, which helps to simplify the user's operation steps and makes it easier for the user to use.

[0089] In some embodiments, please refer to Figure 2 , Figure 7 and Figure 8 The inner cavity 11a has a stop surface 111a on its cavity wall. When the main body 12 is in the second position, the side of the main body 12 facing the first liquid storage tank 10a abuts against the stop surface 111a.

[0090] In this way, by stopping the main body 12 through the stop surface 111a, the maximum space that the first liquid storage chamber 10a can be compressed can be controlled, which helps to reduce the risk of leakage at the atomizing core 22 caused by excessive outflow of aerosol generation matrix.

[0091] In some embodiments, please refer to Figure 2 and Figure 3 The housing 11 includes an outer shell 111 and a guide post 112. The outer shell 111 surrounds the periphery of the guide post 112 and defines an inner cavity 11a with the guide post 112. The main body 12 is annular, and the inner annular surface of the main body 12 is sleeved on the guide post 112.

[0092] Here, the axial direction of the guide post 112 can be parallel to the axial direction of the mounting hole 12a.

[0093] Here, an inner cavity 11a is defined between the inner wall of the outer casing 111 and the outer wall of the guide post 112. The cavity wall of the inner cavity 11a includes a portion of the inner wall of the outer casing 111 and a portion of the outer wall of the guide post 112.

[0094] During the movement of the main body 12, the guide post 112 provides guidance for the main body 12, thereby helping to improve the problem of the main body 12 tilting relative to the direction of movement due to uneven force. This, in turn, improves the stability and reliability of the main body 12 as it moves in the direction of reducing the volume of the first liquid storage tank 10a.

[0095] In some embodiments, the inner annular surface of the main body 12 is sealed to the guide post 112, and the outer annular surface of the main body 12 is sealed to the inner sidewall of the outer casing 111.

[0096] This helps to improve the stability of the sealing fit between the main body 12 and the cavity wall of the inner cavity 11a, thereby reducing the risk of leakage of the liquid storage assembly 10.

[0097] In some embodiments, please refer to Figure 2 , Figure 3 , Figure 7 and Figure 8 The guide post 112 is arranged to form a first installation channel 112a, and at least a portion of the structure of the atomizing core 22 is located within the first installation channel 112a.

[0098] Specifically, please refer to Figure 7 and Figure 8 At least a portion of the atomizing core 22 is disposed within the second mounting channel 211b, and at least a portion of the second mounting channel 211b is located within the first mounting channel 112a.

[0099] Understandably, if the guide post 112 does not have a first mounting channel 112a to accommodate at least part of the atomizer coil 22, then the atomizer would need to have space in other locations to accommodate this part of the atomizer coil 22. This would increase the overall size of the atomizer.

[0100] In this embodiment, the space occupied by the outer wall of the guide post 112 is used to accommodate this part of the atomizing core 22, thereby improving the space utilization of the atomizer. This helps to reduce the size of the atomizer and makes it easier for users to carry.

[0101] In some embodiments, the main body 12 includes only the first component 121.

[0102] The specific material of the first component 121 is not limited. For example, it can be a food-grade material such as silicone.

[0103] When the main body 12 includes only the first component 121, the hardness of the first component 121 only needs to meet the following two requirements:

[0104] Article 1: The first component 121 can produce slight deformation, so that the first component 121 can use this deformation to achieve a sealing fit with the cavity wall of the inner cavity 11a, thereby ensuring the sealing performance of the first liquid storage tank 10a.

[0105] Article 2: During the assembly of the liquid storage component 10 and the atomizing component 20, after a part of the structure of the atomizing seat 21 (e.g., the support 212 mentioned below) comes into contact with the main body 12, the part continues to push the first component 121, the first component 121 and the cavity wall of the inner cavity 11a can still maintain a sealed fit, and the first component 121 as a whole can slide along the cavity wall of the inner cavity 11a.

[0106] In this embodiment, the main body 12 has fewer parts, which facilitates the production of the main body 12 and its assembly on the liquid storage assembly 10, thereby improving the production efficiency of the liquid storage assembly 10.

[0107] In some embodiments, please refer to Figure 2 and Figure 3 The main body 12 includes a first component 121 and a second component 122. The hardness of the second component 122 is greater than that of the first component 121. The first component 121 is sealed to the cavity wall of the inner cavity 11a.

[0108] In this way, the overall rigidity of the main body 12 can be enhanced by the second component 122, which facilitates the movement of the main body 12 by the atomizing seat 21 during the assembly of the atomizing component 20 and the liquid storage component 10. The first component 121 can ensure the sealing fit between the main body 12 and the cavity wall of the inner cavity 11a, which helps to reduce the risk of aerosol generation matrix seeping out from between the main body 12 and the cavity wall of the inner cavity 11a during the movement of the main body 12.

[0109] It is understandable that the first component 121 can be a flexible component, which is a component made of a material that can produce a certain elastic deformation.

[0110] The assembly structure of the second component 122 and the first component 121 is not restricted.

[0111] For example, the first component 121 covers the second component 122. Here, since the second component 122 is not in direct contact with the aerosol generating matrix, there are many possible materials for the second component 122, such as plastic, various metals, etc.

[0112] For example, please refer to Figure 2 and Figure 3The first component 121 has a second component 122 on the side opposite to the first liquid storage tank 10a.

[0113] It should be noted that the second component 122 does not limit the coverage area of ​​the side of the first component 121 away from the first liquid storage tank 10a.

[0114] For example, the first component 121 may cover the second component 122 in the portion of the area where it contacts the atomizing seat 21 to transmit force, and / or the second component 122 may cover the first component 121 at a position close to the cavity wall of the inner cavity 11a where it is sealed. Here, the first component 121 forms a separate mounting hole 12a.

[0115] For example, the second component 122 is close to the side of the first component 121 that is away from the first liquid storage tank 10a. This helps to improve the overall rigidity of the side of the main body 12 that is away from the first liquid storage tank 10a. Here, the first component 121 and the second component 122 together define the mounting hole 12a.

[0116] Here, the second component 122 can also be made of various metals, plastics, etc.

[0117] It should be noted that a second component 122 is provided on the side of the first component 121 that is away from the first liquid storage tank 10a. It is possible that the second component 122 is provided only on the side of the first component 121 that is away from the first liquid storage tank 10a, or the second component 122 is provided on both the side of the first component facing the first liquid storage tank 10a and the side that is away from the first liquid storage tank 10a.

[0118] It is understandable that the materials of the second components 122 on both sides of the first component 121 can be the same or different. Using the same material is beneficial to improving the production efficiency of the main body 12. Since the second component 122 on the side of the first component 121 facing the first liquid storage tank 10a is in direct contact with the aerosol generating matrix, it can be made of food-grade materials such as stainless steel.

[0119] For example, the second component 122 may be provided only on the side of the first component 121 facing the first liquid storage tank 10a.

[0120] In some embodiments, please refer to Figures 7 to 9 The atomizing base 21 also includes a body 211 and a support 212. The body 211 is located on the side of the main body 12 away from the first liquid storage chamber 10a. One end of the lower liquid column 213 and one end of the support 212 are both located on the body 211. As the lower liquid column 213 extends into the first liquid storage chamber 10a, the other end of the support 212 supports the main body 12 and pushes the main body 12 to move.

[0121] It should be noted that during the process of the lower liquid column 213 extending into the first liquid storage chamber 10a, the support body 212 does not need to push the main body 12 to move throughout the entire process. For example, as the lower liquid column 123 gradually extends into the first liquid storage chamber 10a, the support body 212 also gradually approaches the main body 12. Until the support body 212 abuts against the main body 12, the assembly of the atomizing component 20 and the liquid storage component 10 continues, and the support body 212 pushes the main body 12 to the second position.

[0122] The atomizing base 21 pushes the main body 12 to move by means of the support 212, rather than by making the entire area of ​​the side of the atomizing base 21 facing the main body 12 come into contact with the main body 12 to push the main body 12 to move.

[0123] Understandably, the support 212 is relatively small in size, which makes it easier to enter the inner cavity 11a and thus facilitates the movement of the main body 12 from the first position to the second position.

[0124] In some embodiments, please refer to Figure 4 The number of supports 212 is at least three, and the at least three supports 212 are evenly spaced along the circumference of the body 211.

[0125] In this way, as the support 212 pushes the main body 12 to move, it helps to improve the uniformity of the force on the main body 12 and reduces the probability of problems such as tilting during the movement of the main body 12. As a result, it helps to improve the stability and reliability of the main body 12 during the movement in the direction of reducing the volume of the first liquid storage tank 10a, and also helps to improve the stability of the sealing fit between the main body 12 and the cavity wall of the inner cavity 11a, thereby reducing the risk of leakage of the liquid storage assembly 10.

[0126] In some embodiments, please refer to Figure 4 The support body 212 includes a first support body 214, which is attached to the peripheral sidewall of the lower liquid column 213.

[0127] Here, the first support 214 is a type of support 212.

[0128] The first support 214 can be strengthened by the lower liquid column 213. Therefore, the size of the first support 214 can be set relatively small, which helps to simplify the structure of the first support 214 and reduce the production difficulty of the first support 214.

[0129] For example, please refer to Figure 4 The first support 214 includes two support ribs 2141, which are located on opposite sides of the lower liquid column 213. The first support 214 supports the main body 12 through at least two support ribs 2141, thereby pushing the main body 12 to move.

[0130] It should be noted that when the number of lower liquid columns 213 is at least three, at least three first supports 214 can be provided. In this case, the support 212 may only include the first supports 214, and not other types of supports 212 (such as the second support 215 mentioned below).

[0131] In some embodiments, please refer to Figure 4 The support body 212 includes a second support body 215, which is spaced apart from the lower liquid column 213 along the circumference of the body 211.

[0132] The second support 215 is also a type of support 212. The second support 215 can be columnar, which helps to improve the structural strength of the second support 215.

[0133] In some embodiments, please refer to Figure 7 and Figure 8 As the liquid channel 213a extends into the first liquid storage chamber 10a, the area traversed by the side of the main body 12 away from the first liquid storage chamber 10a is the compression chamber 10b. The atomizing seat 21 is also provided with a second liquid storage chamber 21a. The second liquid storage chamber 21a and the atomizing core 22 are in liquid communication. The main body 211 constitutes at least part of the chamber wall of the second liquid storage chamber 21a. The atomizing core 22 includes a liquid guiding component 221 and a heating component 222. The liquid guiding component 221 surrounds the outer periphery of the heating component 222. The volume of the compression chamber 10b is greater than the volume of the second liquid storage chamber 21a, and less than or equal to the sum of the capacity of the liquid guiding component 221 and the volume of the second liquid storage chamber 21a.

[0134] Specifically, please refer to Figure 7 and Figure 8 The atomizing base 21 includes a body 211, which has a liquid guiding hole 211a and a second mounting channel 211b. At least a portion of the atomizing core 22 is located within the second mounting channel 211b, and a second liquid storage chamber 21a surrounds the second mounting channel 211b. The liquid guiding hole 211a is located on the periphery of the second mounting channel 211b. In this way, the aerosol generating matrix in the second liquid storage chamber 21a can be guided through the liquid guiding hole 211a to the atomizing core 22 located in the second mounting channel 211b, thereby generating aerosol under the action of the atomizing core 22.

[0135] Specifically, please refer to Figure 7 and Figure 8 The atomizing seat 21 also includes a sealing seat 216, and the body 211 and the sealing seat 216 define a second liquid storage chamber 21a.

[0136] The specific material of the sealing seat 216 is not limited. For example, it can be a food-grade material such as silicone.

[0137] Specifically, please refer to Figure 2 The liquid storage assembly 10 also includes a base 14, which is connected to the housing 11 and located on the side of the main body 12 opposite to the first liquid storage chamber 10a. When the main body 12 is in the first position, the main body 12 abuts against the base 14. Please refer to [link to relevant documentation]. Figure 7 and Figure 8 When the main body 12 is in the second position, a gap area is formed between the main body 12 and the base 14. The remaining space of this gap area, excluding the space occupied by the lower liquid column 213, is the compression chamber 10b.

[0138] The second liquid storage chamber 21a and the atomizing core 22 are in liquid communication. That is, the aerosol generation matrix in the second liquid storage chamber 21a can be guided to the atomizing core 22.

[0139] It should be noted that the capacity of the liquid guiding component 221 refers to the maximum volume of aerosols it can adsorb to form a matrix.

[0140] It is understandable that the volume of the compression chamber 10b is the volume of the first liquid storage chamber 10a that is reduced, which is approximately the amount of aerosol generation matrix that leaves the first liquid storage chamber 10a when the atomizing component 20 and the liquid storage component 10 are assembled.

[0141] Since the volume of the compression chamber 10b is larger than the volume of the second liquid storage chamber 21a, this part of the aerosol generation matrix can fill the second liquid storage chamber 21a and can contact the atomizing core 22 through the liquid guiding hole 211a. In this way, the user can draw in the atomizing component 20 and the liquid storage component 10 after they are assembled.

[0142] Furthermore, when the liquid guiding component 221 is liquid guiding cotton, the liquid guiding cotton can also adsorb a certain amount of aerosol to generate a matrix.

[0143] By controlling the volume of the compression chamber 10b to be less than or equal to the sum of the capacity of the liquid guide 221 and the volume of the second liquid storage chamber 21a, the probability of leakage at the heating element 222 caused by the atomizing component 20 and the liquid storage component 10 being directly squeezed out through the inside of the liquid guide 221 after assembly can be reduced.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
