[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 atomizers, which include atomizing components and liquid storage components. Based on the atomizing components and liquid storage components with detachable assembly structures, the operation of supplying liquid from the liquid storage components to the atomizing components during the assembly process is relatively complex and inconvenient for users. Utility Model Content

[0004] In view of this, embodiments of this application aim to provide a liquid storage component, an atomizer, and an aerosol generating device, which are designed to facilitate the liquid supply flow path between the liquid storage component and the atomizing 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 inner cavity and an air outlet channel. One side of the inner cavity is open, and one end of the air outlet channel is an air outlet that communicates with the outside atmosphere.

[0008] A base is disposed on the open side of the inner cavity and connected to the housing. The base and the cavity wall of the inner cavity define a liquid storage chamber for containing the aerosol generation matrix. The base is provided with a liquid guiding hole and an installation channel. The liquid guiding hole is located on the periphery of the installation channel and connects the liquid storage chamber and the installation channel. The two ends of the installation channel are respectively connected to the other end of the gas outlet channel and the outside of the liquid storage component.

[0009] A switch element is movably disposed within the mounting channel along the axial direction of the mounting channel, and the switch element moves along the axial direction of the mounting channel to selectively open or seal the liquid guide hole.

[0010] In some embodiments, the housing includes an outer shell and an inner shell disposed within the outer shell, the inner shell having the air outlet channel, and the inner shell and the outer shell being connected at one end near the air outlet and defining the inner cavity;

[0011] The base includes a connector and a sleeve. The sleeve has the installation channel and the liquid guiding hole. The sleeve is connected to the end of the inner shell away from the air outlet through the connector.

[0012] In some embodiments, the inner shell is provided with a first limiting surface, the end of the connector near the air outlet abuts against the first limiting surface, the connector is provided with a second limiting surface, and the end of the sleeve near the air outlet abuts against the second limiting surface.

[0013] In some embodiments, the base further includes a sealing ring, at least a portion of the sleeve is disposed within the sealing ring and the ends of both are sealed together away from the air outlet, the end of the sealing ring near the air outlet is spaced apart from the sleeve and defines a liquid discharge channel, and the liquid storage tank is connected to the liquid guide hole through the liquid discharge channel.

[0014] In some embodiments, the inner annular surface of the sealing ring includes a first annular surface and a second annular surface, wherein the first annular surface is closer to the liquid storage tank than the second annular surface;

[0015] In the radial direction of the sleeve, the distance between the first annular surface and the sleeve is greater than the distance between the second annular surface and the sleeve.

[0016] In some embodiments, the distance between the second annular surface and the sleeve in the radial direction of the sleeve is 1 mm to 2 mm.

[0017] In some embodiments, the sealing ring has a liquid guiding groove, at least a portion of which is disposed on the second annular surface and extends axially along the sleeve.

[0018] This application embodiment provides an atomizer, the atomizer comprising:

[0019] The liquid storage assembly described in any of the above embodiments; and

[0020] An atomizing assembly includes an atomizing core, at least a portion of which is disposed within the mounting channel, and the atomizing core, as it extends into the mounting channel, pushes the switching element from a position sealing the liquid guide hole to a position opening the liquid guide hole.

[0021] In some embodiments, the switch is annular and has a stepped surface on its inner sidewall. One end of the atomizing core extends into the switch and abuts against the stepped surface to push the switch to a position where the liquid guide hole is opened.

[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 atomizing core.

[0025] In this embodiment of the liquid storage assembly, the switch element is movably disposed within the mounting channel along the axial direction of the mounting channel. When the liquid storage assembly stores the aerosol generation matrix alone, the switch element seals the liquid guide hole, thereby reducing the probability of leakage. During the assembly of the atomizing assembly and the liquid storage assembly, the atomizing assembly is pushed into the mounting channel, and the pushing force is transmitted to the switch element, which can then move along the axial direction of the mounting channel to a position where the liquid guide hole is opened. This opens the liquid supply path between the liquid storage assembly and the atomizing assembly, facilitating user operation.

[0026] In addition, the base is directly connected to the housing, and the switch can be used only to open or seal the liquid guide hole. During the axial movement of the switch along the installation channel, the impact on the connection between the base and the housing is relatively small, which helps to improve the connection stability and reliability between the base and the housing.

[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 4 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 assembly 10 and an atomizing assembly. The liquid storage assembly 10 is used to contain an aerosol generating matrix, and the atomizing assembly is electrically connected to a power supply assembly to heat and atomize the aerosol generating matrix.

[0050] In some embodiments, the liquid storage component 10 and the atomizing component can be assembled using a detachable assembly structure. In this way, once the aerosol generating matrix contained in the liquid storage component 10 is used up, a new liquid storage component 10 can be replaced, and the atomizing component does not need to be replaced. This also 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 itself may not store the aerosol generation matrix.

[0052] In related technologies, based on atomizing components and liquid storage components with detachable assembly structures, there is a risk of leakage when the liquid storage component alone contains the aerosol generating matrix. In the process of assembling the atomizing component and the liquid storage component, it is necessary not only to establish the connection between the atomizing component and the liquid storage component, but also to supply liquid from the aerosol generating matrix contained in the liquid storage component to the atomizing component. As such, the operation is relatively cumbersome, and it is inconvenient for users to replace the liquid storage component themselves.

[0053] 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, a base 12, and a switch 13.

[0054] Furthermore, this application provides an atomizer; please refer to [link to relevant documentation]. Figure 4 The atomizer includes an atomizing component 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] The housing 11 has an inner cavity 11a, one side of which is open. The base 12 is located on the open side of the inner cavity 11a and connected to the housing 11. The base 12 and the cavity wall of the inner cavity 11a define a liquid storage chamber 10a, which is used to contain the aerosol generation matrix.

[0057] For example, please refer to Figure 2 and Figure 3 The bottom side of the inner cavity 11a is open.

[0058] 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 1 , Figure 2 and Figure 4 The direction indicated by H in the middle.

[0059] 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 liquid storage tank 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.

[0060] The base 12 is provided with a liquid guiding hole 122a and an installation channel 122b. The liquid guiding hole 122a is located on the periphery of the installation channel 122b and connects the liquid storage chamber 10a and the installation channel 122b. The atomizing component includes an atomizing core 20, at least a portion of which is located within the installation channel 122b.

[0061] In this way, the aerosol generation matrix in the liquid storage chamber 10a can enter the installation channel 122b through the liquid guiding hole 122a, thereby guiding it to the atomizing core 20 and generating aerosol under the action of the atomizing core 20.

[0062] In some embodiments, the atomizing core 20 includes a liquid guiding element and a heating element. The heating element 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 an aerosol. The liquid guiding element transmits or delivers the aerosol generating matrix to the heating element through capillary action or other forces. The material of the liquid guiding element includes, but is not limited to, ceramics, glass, quartz, or fiber.

[0063] Of course, in other embodiments, the liquid guiding element may be omitted.

[0064] The specific method by which the heating element heats the aerosol to form a matrix is ​​not limited. Examples include resistance heating, electromagnetic induction heating, infrared heating, microwave heating, laser heating, air heating, electric field heating, carbon source heating, plasma heating, etc.

[0065] Specifically, the heating element 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.

[0066] 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.

[0067] The housing 11 is also provided with an air outlet 112a, one end of which is an air outlet 112b, which is connected to the outside atmosphere. The two ends of the installation channel 122b are respectively connected to the other end of the air outlet 112a and the outside of the liquid storage component 10.

[0068] In this way, the atomizing core 20 can extend into the mounting channel 122b from one end and be installed in the mounting channel 122b. The aerosol generated at the atomizing core 20 can enter the air outlet channel 112a through the end of the air outlet channel 112a that is connected to the mounting channel 122b, and then flow out through the air outlet 112b for the user to use.

[0069] The switch element 13 is movably disposed within the mounting channel 122b along the axial direction of the mounting channel 122b. The switch element 13 moves along the axial direction of the mounting channel 122b to selectively open or seal the liquid guide hole 122a.

[0070] The specific shape of the switch element 13 is not limited. For example, please refer to [reference needed]. Figure 2 and Figure 3 The switch element 13 is annular, and the outer wall of the annular switch element 13 abuts against the side wall of the mounting channel 122b. In this way, the liquid guide hole 122a can be sealed better, thereby reducing the probability of leakage problems in the liquid storage assembly 10.

[0071] The specific material of the switch element 13 is not limited. For example, the switch element 13 can be made of a material capable of slight elastic deformation, which helps improve the sealing performance of the switch element 13 for the liquid guide hole 122a. Specifically, the material capable of slight elastic deformation can be silicone, which is a food-grade material and beneficial to the user's health.

[0072] As the atomizing core 20 extends into the mounting channel 122b, it pushes the switch element 13 from the position of sealing the liquid guide hole 122a to the position of opening the liquid guide hole 122a.

[0073] When the liquid storage component 10 stores the aerosol generation matrix alone, the liquid guide hole 122a is sealed by the switch component 13. In this way, the flow path between the liquid storage chamber 10a and the installation channel 122b is blocked, which makes it easier for the liquid storage component 10 to realize the function of storing the aerosol generation matrix alone and reduces the probability of leakage problems in the liquid storage component 10.

[0074] When replacing the liquid reservoir assembly 10 of the atomizer, the atomizing coil 20 is pushed into the mounting channel 122b from the end away from the air outlet 112b. After the atomizing coil 20 touches the switch element 13, it is pushed further into the mounting channel 122b, thereby transmitting the pushing force to the switch element 13, causing the switch element 13 to move axially along the mounting channel 122b, thus opening the liquid guide hole 122a. In this way, the liquid supply path between the liquid reservoir assembly 10 and the atomizing assembly can be simultaneously opened during the assembly process of the atomizing assembly and the liquid reservoir assembly 10, which is convenient for the user.

[0075] In summary, in this embodiment of the liquid storage assembly 10, the switch element 13 is movably disposed within the mounting channel 122b along the axial direction of the mounting channel 122b. When the liquid storage assembly 10 stores the aerosol generation matrix alone, the switch element 13 seals the liquid guide hole 122a, thereby reducing the probability of leakage in the liquid storage assembly 10. During the assembly of the atomizing assembly and the liquid storage assembly 10, the atomizing assembly (specifically, the atomizing core 20) is pushed into the mounting channel 122b, and the pushing force is transmitted to the switch element 13 by the atomizing assembly (specifically, the atomizing core 20), thereby pushing the switch element 13 to move axially along the mounting channel 122b to the position where the liquid guide hole 122a is opened. In this way, the liquid supply flow path between the liquid storage assembly 10 and the atomizing assembly can be opened, thus facilitating user operation.

[0076] Furthermore, the base 12 is directly connected to the housing 11, and the switch 13 can be used only to open or seal the liquid guide hole 122a. During the axial movement of the switch 13 along the mounting channel 122b, the impact on the connection relationship between the base 12 and the housing 11 is relatively small, which is beneficial to improving the connection stability and reliability between the base 12 and the housing 11.

[0077] In some embodiments, please refer to Figures 3 to 5 The switch 13 is annular, and a stepped surface 131 is provided on the inner side wall of the switch 13. One end of the atomizing core 20 extends into the switch 13 and abuts against the stepped surface 131 to push the switch 13 to move to the position where the liquid guide hole 122a is opened.

[0078] In this way, one end of the atomizing core 20 can extend into the switch element 13, allowing the outer wall of the atomizing core 20 to fit against the inner wall of the switch element 13. Thus, the switch element 13 can provide a certain positioning effect for the atomizing core 20, reducing the likelihood of the atomizing core 20 wobbling as it moves the switch element 13, and helping the atomizing core 20 better maintain axial movement along the mounting channel 122a.

[0079] It is understandable that the closer the movement directions of the atomizing core 20 and the switch 13 are to parallel, the smoother and less effort it is to push the switch 13 to move, which is conducive to the proper assembly of the atomizing component and the liquid storage component 10.

[0080] Furthermore, the end face of the atomizing core 20 does not abut against the end face of the switch 13 away from the air outlet channel 112a. In this way, the aerosol generated at the atomizing core 20 is less obstructed by the switch 13, making it easier for the aerosol to enter the air outlet channel 11a for user use.

[0081] Of course, in other embodiments, the switch 13 may not have the stepped surface 131. One end of the atomizing core 20 abuts against the end face of the switch 13 away from the air outlet channel height 112a, which can also push the switch 13 to the position where the liquid guide hole 122a is opened.

[0082] In some embodiments, please refer to Figure 2 and Figure 3 The housing 11 includes an outer shell 111 and an inner shell 112 disposed within the outer shell 111. The inner shell 112 is provided with an air outlet channel 112a. The inner shell 112 and the outer shell 111 are connected and defined at one end near the air outlet 112b to form an inner cavity 11a. The base 12 includes a connector 121 and a sleeve 122. The sleeve 122 is provided with an installation channel 122b and a liquid guide hole 122a. The sleeve 122 is connected to the end of the inner shell 112 away from the air outlet 112b through the connector 121.

[0083] The specific shape of the connector 121 is not limited. For example, the connector 121 is annular. This allows for a sleeve-like connection between the connector 121 and the sleeve 122, and similarly, a sleeve-like connection between the connector 121 and the inner shell 112. Thus, any circumferential position at one end of the sleeve 122 and any circumferential position at one end of the inner shell 112 has a connection area with the connector 121, which improves the reliability of the connection between the sleeve 122, the connector 121, and the inner shell 112. Simultaneously, it helps reduce the probability of air leakage at the joint between the air outlet channel 112a and the installation channel 122b.

[0084] It should be noted that there are no restrictions on the specific way the annular connector 121 is fitted onto the sleeve 122. For example, the connector 121 can be fitted onto one end of the sleeve 122; or one end of the sleeve 122 can be fitted onto the connector 121.

[0085] Of course, there are no restrictions on the specific way in which the annular connector 121 is sleeved with the inner shell 112. For example, the connector 121 can be sleeved on one end of the inner shell 112; or, one end of the inner shell 112 can be sleeved on the connector 121.

[0086] It is understandable that the connector 121 may only be used to realize the connection between the sleeve 122 and the inner shell 112, while the sleeve 122 needs to accommodate the atomizing core 20 and needs to slide relative to the switch 13.

[0087] The sleeve 122 is connected to the inner shell 112 via the connector 121. The sleeve 122 and the connector 121 can be made of different materials. For example, the connector 121 can be made of a material that is conducive to improving the reliability of the connection, while the sleeve 122 can be made of a material that facilitates relative sliding between it and the switch 13.

[0088] In this way, while improving the reliability of the connection between the sleeve 122, the connector 121 and the inner shell 112, it also makes it easier to reduce the difficulty of the switch 13 sliding relative to the sleeve 122, so that the user can push the switch 13 through the atomizing component to switch the switch 13 between the position of opening the liquid guide hole 122a and the position of sealing the liquid guide hole 122a.

[0089] In some embodiments, please refer to Figure 2 and Figure 3 The inner shell 112 is provided with a first limiting surface 112c, and the end of the connector 121 near the air outlet 112b abuts against the first limiting surface 112c. The connector 121 is provided with a second limiting surface 1212a, and the end of the sleeve 122 near the air outlet 112b abuts against the second limiting surface 1212a.

[0090] The location of the first limiting surface 112c is not restricted.

[0091] For example, please refer to Figure 2 and Figure 3 In an embodiment where one end of the connector 121 is fitted onto the outer wall of the inner shell 112, the first limiting surface 112c can be located on the outer wall of the inner shell 112. It is understood that the machining space on the outer wall of the inner shell 112 is relatively large, facilitating the machining of the first limiting surface 112c.

[0092] For example, in an embodiment where one end of the connector 121 is located on the inner wall of the inner shell 112 (i.e., the side wall of the air outlet channel 112a), the first limiting surface 112c may be located on the inner wall of the inner shell 112.

[0093] The location of the second limiting surface 1212a is also not restricted.

[0094] For example, please refer to Figure 2 and Figure 3In an embodiment where one end of the sleeve 122 is fitted onto the outer wall of the connector 121, the second limiting surface 1212a can be located on the outer wall of the connector 121. It is understood that the machining space on the outer wall of the connector 121 is relatively large, facilitating the machining of the second limiting surface 1212a.

[0095] For example, in an embodiment where one end of the sleeve 122 is located on the inner wall of the connector 121, the second limiting surface 1212a may be located on the inner wall of the connector 121.

[0096] In this embodiment, when the atomizing core 20 pushes the switch 13 to slide upward, the pushing force is transmitted to the sleeve 122 through the friction between the switch 13 and the sleeve 122. The connector 121 can restrict the upward movement of the sleeve 122 via the second limiting surface 1212a, while the inner shell 112 can restrict the upward movement of the connector 121 via the first limiting surface 112c. This improves the reliability of the connection between the sleeve 122, the connector 121, and the inner shell 112. Consequently, it helps to improve the reliability of the liquid storage assembly 10 and the atomizing assembly during assembly, preventing leakage, air leakage, or even connection failure of various components of the liquid storage assembly 10 due to the sleeve 122 and connector 121 being driven by the switch 13.

[0097] The specific method by which the second limiting surface 1212a is set on the connector 121 is not limited.

[0098] For example, please refer to Figure 2 and Figure 3 The connector 121 includes a body 1211 and a stop portion 1212. The body 1211 is annular, thereby fitting into the sleeve 122 and the inner shell 112 respectively. The stop portion 1212 extends outward from the outer side wall of the body 1211, and the side of the stop portion 1212 away from the air outlet 112b in the thickness direction constitutes the second limiting surface 1212a.

[0099] In this embodiment, the structure of the connector 121 is relatively simple, which facilitates the setting of the second limiting surface 1212a.

[0100] In some embodiments, please refer to Figure 2 and Figure 3 122 is a metal sleeve.

[0101] The specific material of the metal sleeve is not limited. For example, the sleeve 122 can be made of food-grade metal material. Since the sleeve 122 is in direct contact with the aerosol generating matrix, the sleeve 122 made of food-grade metal material is more beneficial to the user's health.

[0102] For example, food-grade metal materials include, but are not limited to, 304 stainless steel, 316 stainless steel, 430 stainless steel, etc.

[0103] In this embodiment, the sleeve 122 is made of metal, and the surface of the metal sleeve is smoother. During the sliding process of the switch 13 inside the sleeve 122, less force is required. Therefore, it is easier for the user to push the atomizing component and push the switch 13 to slide on the inner wall of the sleeve 122 through the atomizing core 20.

[0104] In other embodiments, the sleeve 122 may also be made of materials such as silicone. In this way, the friction between the switch 13 and the sleeve 122 is greater, and the switch 13 is positioned to seal the liquid guide hole 122a, which improves the sealing effect of the liquid guide hole 122a and helps to reduce the probability of leakage problems in the liquid storage component 10 during transportation or storage.

[0105] In some embodiments, please refer to Figure 2 and Figure 3 The base 12 also includes a sealing ring 123. At least a portion of the sleeve 122 is disposed within the sealing ring 123 and the ends of both are sealed together away from the air outlet 112b. The end of the sealing ring 123 near the air outlet 112b is spaced apart from the sleeve 122 and defines a liquid discharge channel 12a. The liquid storage tank 10a is connected to the liquid guide hole 122a through the liquid discharge channel 12a.

[0106] The specific material of the sealing ring 123 is not limited. For example, it can be a food-grade material such as silicone.

[0107] Here, the outer wall of the sealing ring 123 is sealed and fitted with the cavity wall of the inner cavity 11a, while the outer wall of the end of the sleeve 122 away from the air outlet 112b is sealed and fitted with the inner wall of the sealing ring 123. This helps to improve the sealing performance between the sleeve 122 and the cavity wall of the inner cavity 11a, thereby improving the sealing performance of the liquid storage tank 10a and reducing the probability of leakage problems in the liquid storage assembly 10.

[0108] In some embodiments, please refer to Figure 2 and Figure 3 The inner ring surface of the sealing ring 123 includes a first ring surface 1231 and a second ring surface 1232. The first ring surface 1231 is closer to the liquid storage chamber 10a than the second ring surface 1232. In the radial direction of the sleeve 122, the distance between the first ring surface 1231 and the sleeve 122 is greater than the distance between the second ring surface 1232 and the sleeve 122.

[0109] For example, the distance between the first annular surface 1231 and the sleeve 122 is as follows: Figure 3 As shown in d1, the distance between the second annular surface 1232 and the sleeve 122 is as follows: Figure 3 As shown in d2.

[0110] Thus, the liquid discharge channel 12a includes at least two flow channels with unequal diameters. The portion of the liquid discharge channel 12a between the first annular surface 1231 and the sleeve 122 is the first flow channel, and the portion of the liquid discharge channel 12a between the second annular surface 1232 and the sleeve 122 is the second flow channel. The diameter of the first flow channel is larger than the diameter of the second flow channel.

[0111] In other words, the thickness of the sealing ring 123 in the region where the second annular surface 1232 is located is greater than the thickness of the region where the first annular surface 1231 is located.

[0112] Understandably, when filling the liquid storage assembly 10, the open side of the inner cavity 11a is usually facing upwards, and the aerosol generating matrix is ​​injected into the inner cavity 11a from the open side. Then, the base 12 is placed on the open side to seal the inner cavity 11a. However, during use, the liquid storage assembly 10 needs to be inverted (i.e., the open side of the inner cavity 11a faces downwards). During this inversion, some of the aerosol generating matrix will enter the lower liquid channel 12a, causing the liquid level in the storage tank 10a to drop, the bubbles to become larger, and the user experience to be poor.

[0113] In this embodiment, the first flow channel has a sufficient diameter to facilitate the entry of the aerosol generation matrix in the liquid storage tank 10a into the liquid lower channel 12a. By increasing the thickness of the sealing ring 123 in the area where the second annular surface 1232 is located, the diameter of the second flow channel is reduced. This reduces the overall volume of the liquid lower channel 12a. After the atomizing component and the liquid storage component 10 are assembled and the atomizing component is positioned below the liquid storage tank 10a, the amount of aerosol generation matrix flowing into the liquid lower channel 12a is reduced. This helps to reduce the drop height of the liquid level in the liquid storage tank 10a and reduce air bubbles in the liquid storage tank 10a.

[0114] In some embodiments, please refer to Figure 2 and Figure 3 In the radial direction of the sleeve 122, the distance between the second annular surface 1232 and the sleeve 122 is 1mm to 2mm. For example, it is 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm, etc.

[0115] In this way, the diameter of the second flow channel is more suitable. On the one hand, the distance between the second annular surface 1232 and the sleeve 122 will not be less than 1mm, that is, the diameter of the second flow channel will not be too small. The aerosol generating matrix can enter the second flow channel relatively smoothly and enter the installation channel 122b through the liquid guiding hole 122a. In this way, it is convenient for a sufficient amount of aerosol generating matrix to enter the atomizing core 20, reducing the probability of the atomizing core 20 dry burning. At the same time, it is also convenient for the atomizing core 20 to generate enough aerosol for the user, thereby ensuring the aerosol inhalation taste. On the other hand, the distance between the second annular surface 1232 and the sleeve 122 will not be greater than 2mm, that is, the diameter of the second flow channel will not be too large. This is conducive to further controlling the total volume of the liquid channel 12a, thereby further controlling the drop height of the liquid level in the liquid storage tank 10a.

[0116] In some embodiments, please refer to Figure 2 and Figure 3 The stop portion 1212 forms a folded edge along the outer edge of the connector 121 in the radial direction. The folded edge is spaced apart from the sleeve 122, and at least a portion of the folded edge extends into the liquid channel 12a.

[0117] In this way, the folded edge can further reduce the total volume of the liquid channel 12a, thereby reducing the drop height of the liquid level in the storage tank 10a.

[0118] Furthermore, one end of the sleeve 122 near the air outlet 112b is located between the flange and the body 1211, and abuts against the stop portion 1212. This helps to improve the connection stability and reliability between the connector 121 and the sleeve 122.

[0119] In some embodiments, please refer to Figure 2 , Figure 3 , Figure 6 and Figure 7 The sealing ring 123 has a liquid guiding groove 1233a, at least a portion of which is located on the second annular surface 1232 and extends along the axial direction of the sleeve 122.

[0120] The specific manner in which the sealing ring 123 is provided with the liquid guiding groove 1233a is not limited. For example, the sealing part 123 may include a liquid guiding part 1233, at least a portion of which is provided on the second annular surface 1232 and extends along the axial direction of the sleeve 122, and the liquid guiding groove 1233a is provided through the liquid guiding part 1233.

[0121] The liquid guiding part 1233 can further occupy the space between the second annular surface 1232 and the sleeve 122, which is conducive to further reducing the total volume of the liquid channel 12a, thereby helping to further reduce the drop height of the liquid level in the liquid storage tank 10a.

[0122] In addition, the diameter of the liquid-feeding channel 12a between the second annular surface 1232 and the sleeve 122 is relatively small, which may result in a small amount of aerosol generation matrix entering the atomizing core 20 due to difficulty in liquid feeding, thus causing the atomizing core 20 to burn dry or the aerosol to have a poor taste.

[0123] In this embodiment, the liquid guiding groove 1233a has a certain liquid guiding effect, which facilitates the flow of aerosol from the end of the second annular surface 1232 near the first annular surface 1231 to the end away from the first annular surface 1231. This guides the aerosol generation matrix to the bottom of the liquid channel 12a, allowing the aerosol generation matrix to enter the installation channel 122b through the liquid guiding hole 122a, thereby guiding liquid to the atomizing core 20. This helps to improve the problems of dry burning of the atomizing core 20 or poor aerosol taste.

[0124] The specific number of liquid guiding sections 1233 is not limited. For example, please refer to [link to example]. Figure 6 and Figure 7 There are multiple liquid guiding parts 1233, and each liquid guiding part 1233 is arranged at intervals along the circumference of the second annular surface 1232.

[0125] The specific number of liquid guiding holes 122a is not limited. For an example, please refer to [link to example]. Figure 6 and Figure 7 There are multiple liquid guiding holes 122a, and each liquid guiding hole 122a is arranged at intervals along the circumference of the second annular surface 1232.

[0126] Furthermore, the number of liquid guiding parts 1233 and liquid guiding holes 122a can be in a one-to-one correspondence.

[0127] In some embodiments, please refer to Figure 6 and Figure 7 The projection of the liquid guiding hole 122a onto the second annular surface 1232 along the axial direction of the liquid guiding hole 122a has an overlapping area with the projection of the liquid guiding part 1233.

[0128] Specifically, regarding a particular liquid guiding hole 122a, when the liquid guiding hole 122a is projected onto the second annular surface 1232 along its axial direction, at least a portion of the projection of the liquid guiding hole 122a will cover the liquid guiding portion 1233. Specifically, when the outer contour of the projection of the liquid guiding hole 122a overlaps with the outer edge of the liquid guiding portion 1233, it is also considered that there is an overlapping area between the projection of the liquid guiding hole 122a and the projection of the liquid guiding portion 1233.

[0129] In this embodiment, the aerosol generating matrix that flows through the liquid guiding section 1233 to the bottom of the second annular surface 1232 is closer to the liquid guiding hole 122a, which makes it easier for this part of the aerosol generating matrix to be guided to the atomizing core 20 through the liquid guiding hole 122a, thereby improving the liquid supply efficiency of the atomizer.

[0130] It should be noted that there are no restrictions on the specific manner in which the liquid guiding part 1233 forms the liquid guiding groove 1233a.

[0131] In some embodiments, please refer to Figure 6 and Figure 7 The liquid guiding part 1233 includes a plurality of ribs 12331 extending axially along the sleeve 122. Each rib 12331 is arranged circumferentially along the second annular surface 1232, and a liquid guiding groove 1233a is defined between two adjacent ribs 12331.

[0132] In this way, the liquid guiding part 1233 can generate a certain capillary force, thereby guiding the flow of the aerosol generation matrix. The aerosol generation matrix in the region of the first annular surface 1231 enters the region of the second annular surface 1232 under the action of the capillary force, which is conducive to further improving the liquid supply efficiency of the atomizer.
