Detailed Implementation

[0029] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0030] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0031] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0032] As shown in Figures 1 to 4, this application provides an atomizing device 1, which can atomize a liquid matrix for user use. The atomizing device 1 may include an atomizing main unit 10 and an atomizer 20. The atomizer 20 is detachably mounted on the atomizing main unit 10 and is used to atomize the liquid matrix after being connected to a power source. The atomizing main unit 10 provides power to the atomizer 20 and controls the atomization operation of the atomizer 20.

[0033] As shown in Figures 2 to 4, the atomizing host 10 may include a housing 11, a main control module 12, and a battery 13. The main control module 12 and the battery 13 are respectively disposed within the housing 11. The housing 11 also defines an atomizer receiving cavity 114 with one open end, into which the atomizer 20 can be detachably inserted.

[0034] The main control module 12 may include a main control board 121, on which a control unit (not shown in the figure) can be mounted. This control unit can be electrically connected to the atomizer 20 to control the atomization operation of the atomizer 20. The main control board 121 can be fixed to the inner wall of the housing 11 to position the main control module 12 within the housing 11. The battery 13 can be electrically connected to the control unit to supply power to the atomizer 20 via the control unit.

[0035] In some embodiments, the main control module 12 may further include an electrical connection structure. When the atomizer 20 is assembled onto the atomizing host 10, at least a portion of the main control board 121 may be disposed opposite to the atomizer 20. The electrical connection structure may be disposed between the main control board 121 and the atomizer 20, and electrically connected to the control unit on the atomizer 20 and the main control board 121 respectively, thereby realizing the electrical connection between the control unit and the atomizer 20.

[0036] This application directly fixes the main control board 121 inside the housing 11, eliminating the need for a separate mounting base for the main control board 121. This reduces the number of components in the atomizing host and lowers production costs. The reduction in components also improves space utilization and reduces space occupation. Furthermore, during assembly, the steps of installing the main control board 121 to the mounting base and then assembling the mounting base into the housing 11 are eliminated, thus simplifying the assembly process and improving production efficiency.

[0037] It should be understood that the atomizing device 1 can be applied to various fields such as electronic cigarettes, medical, and beauty, without specific limitations. The atomizer 20 is not limited in its atomization method for liquid substrates; for example, it can use one or more of the following atomization methods: resistance heating, electromagnetic heating, infrared heating, chemical heating, ultrasonic atomization, and plasma heating.

[0038] As shown in Figures 3 and 4, the casing 111 is generally a flat, hollow columnar structure. Its cross-section perpendicular to the axial direction of the casing 111 is generally a flat ellipse or racetrack shape. Of course, the casing 111 can also be set as a cylindrical, polygonal columnar, irregular columnar, or other shapes.

[0039] In some embodiments, the housing 111 may include a housing 111, a base 112, and a battery housing 113. At least a portion of the housing 111 defines an atomizer receiving cavity 114 open at both ends. The base 112 is open at one end and also defines a main control cavity 1121A with one open end. This main control cavity 1121A can communicate with one end of the atomizer receiving cavity 114, and the other end of the atomizer receiving cavity 114 can be considered as the open end for inserting the atomizer 20. The main control module 12 is disposed within the main control cavity 1121A and corresponds to the atomizer receiving cavity 114 to facilitate electrical connection with the atomizer 20. The housing 111 may also define at least a portion of a battery receiving cavity 115, within which the battery 13 is disposed.

[0040] The atomizer housing 114 and the battery housing 115 can be arranged side-by-side within the casing 111. The casing 111 can be open at both ends and has a first end and a second end opposite to each other. The base 112 can be disposed at the second end of the casing 111 to seal that end. The battery housing 113 can seal part of the first end of the casing 111. The remaining open portion of the first end of the casing 111 can be regarded as the open end of the atomizer housing 114.

[0041] It should be understood that the base 112 and the battery case 113 can be assembled together detachably or non-detachably through snap-fit ​​connection, guide rail connection, threaded connection, one-piece molding, bolt connection, glue bonding, etc., without specific limitations.

[0042] In some embodiments, the housing 111 may include a housing 1111 and at least one partition structure 1112. The partition structure 1112 is disposed on the inner wall surface of the housing 1111, extending from a first end to a second end, such that it is parallel to the axial direction of the housing 111. The partition structure 1112 can separate the battery receiving cavity 115 from the atomizer receiving cavity 114. By providing the partition structure 1112, the assembly operation of the electronic atomizing device 1 can be further facilitated.

[0043] In some embodiments, each partition structure 1112 may include at least one protruding rib, which may be longitudinally arranged and extend along the axial direction of the housing 111. There is a gap between the two partition structures 1112 located on opposite sidewalls of the housing 1111, and the atomizer housing 114 and the battery housing 115 can be connected through the gap between the two partition structures 1112.

[0044] In some other alternative embodiments, the number of the partition structure 1112 may also be one, which may be a plate-like structure, horizontally disposed within the housing 1111, so as to separate the atomizer housing 114 and the battery housing 115 from each other.

[0045] As shown in Figure 2, in some embodiments, the battery casing 113 can be at least partially detachably inserted into the housing 111 from its first end and disposed on one side of the partition structure 1112, thereby limiting its position within the housing 111. In some embodiments, the battery casing 113 can be configured as various shapes such as cylindrical, polygonal, irregular, disc-shaped, semi-circular, or elliptical, without specific limitations.

[0046] Referring to Figures 3 and 4 together, in some embodiments, the battery casing 113 may include a connecting portion 1131 and a sealing portion 1132. The connecting portion 1131 is hollow and is inserted into the battery receiving cavity 115 from its first end, at least partially connected to the inner wall of the casing 111. The sealing portion 1132 covers one end of the connecting portion 1131 and protrudes from the first end of the casing 111, thus cooperating with the connecting portion 1131 and the casing 111 to seal the battery within the battery receiving cavity 115.

[0047] As shown in Figures 2 and 4, the end of the connecting portion 1131 away from the sealing portion 1132 can be through-hole, so that the battery case 113 as a whole has a structure with one end open and the other end closed. The portion of the base 112 corresponding to the battery case 113 can define a battery cavity 1121B. The battery cavity 1121B can be connected to the space inside the battery case 113 through the open end of the battery case 113, together forming the battery receiving cavity 115.

[0048] In some embodiments, the outer contour dimension of the end of the cover portion 1132 connected to the connecting portion 1131 can be slightly larger than the outer contour dimension of the end of the connecting portion 1131 connected to the cover portion 1132, and smoothly transition to the outer surface of the housing 111 to improve the appearance and smoothness of the outer surface of the housing 11, thereby improving the user experience.

[0049] It should be understood that the connecting part 1131 and the cover part 1132 can be detachably or non-detachably connected by means of threaded connection, bolt connection, adhesive bonding, interference fit, snap connection, integral molding, etc., without specific limitations.

[0050] In some other alternative embodiments, the cover 1132 may also be located inside the battery housing cavity 115 and cover its top, smoothly transitioning to the outer surface of the housing 111.

[0051] In some other alternative embodiments, the battery case 113 may also include a cover portion 1132.

[0052] In some other alternative embodiments, the end of the connecting portion 1131 away from the cover portion 1132 may also be a closed end, and the battery receiving cavity 115 may be entirely located within the housing 111. In this embodiment, the main control module 12 may be partially disposed within the main control cavity 1121A and partially disposed within the battery cavity 1121B.

[0053] As shown in Figure 2, in some embodiments, a portion of the sidewall of the battery casing 113 can be adjacent to a portion of the sidewall of the atomizer 20 to improve the utilization rate of the space inside the casing 111.

[0054] In some embodiments, the atomizer 20 may also be detachably connected to the battery housing 113.

[0055] As shown in Figures 3 and 4, one of the battery housing 113 and the atomizer 20 is provided with a mounting protrusion 1133, and the other is provided with a mounting groove 2111. When the atomizer 20 is inserted into the housing 111, the mounting protrusion 1133 is detachably limited within the mounting groove 2111, thereby achieving a locking and limiting connection between the atomizer 20 and the battery housing 113.

[0056] In some other alternative embodiments, the battery housing 113 and the atomizer 20 may also be spaced apart. A separator 1112 is sandwiched between them to achieve a blocking effect.

[0057] As shown in Figure 2, in some embodiments, the base 112 can be at least partially inserted into the second end of the housing 111 to seal the second end of the housing 111. Referring also to Figures 3 and 4, the base 112 can partially protrude outward from the second end of the housing 111, and its outer surface smoothly transitions to the outer surface of the second end of the housing 111 to ensure the smoothness and aesthetics of the housing 11. The portion inserted into the housing 111 can be detachably connected to the housing 111 by means of snap-fit ​​connections, bolt connections, etc., to facilitate the removal of the main control module 12 and the battery 13, thus facilitating the user's replacement, repair, or disassembly and recycling of components.

[0058] As shown in Figure 3, in some embodiments, when the partition structure 1112 extends to the second end of the housing 111, at least one connecting groove 1121C may be provided on the base 112. The number and location of the connecting grooves 1121C may correspond to the partition structure 1112 to make way for the partition structure 1112.

[0059] In some other alternative embodiments, a portion of the base 112 may also surround the outer periphery of the second end of the housing 111.

[0060] In some embodiments, the base 112 may include a seat body 1121 and at least two first limiting members 1123. The seat body 1121 covers the second end of the housing 111, and the first limiting members 1123 are disposed inside the seat body 1121 to limit the main control board 121, thereby fixing the main control module 12 inside the housing 11.

[0061] In some embodiments, the first limiting member 1123 may be in the form of a rib, which may be spaced apart on the side wall of the seat 1121 and located at the position corresponding to the atomizer receiving cavity 114 of the seat 1121, so that the main control board 121 is positioned in the main control cavity 1121A.

[0062] In some embodiments, at least two first limiting members 1123 may be provided with a snap-fit ​​structure 1122. The snap-fit ​​structure 1122 may be in the shape of a slot to support and engage the main control board 121, thereby limiting its position on the base 1121.

[0063] In some other alternative embodiments, the snap-fit ​​structure 1122 can also be configured as a protruding snap-fit ​​structure, and the snap-fit ​​connection between the outer shell 11 and the main control board 121 can also be achieved by correspondingly providing a slot on the outer periphery of the main control board 121. In this embodiment, the base 112 may also omit the first limiting member 1123, and the snap-fit ​​structure 1122 may be directly disposed on the inner wall of the base 1121.

[0064] In some other optional embodiments, the first limiting member 1123 can also be configured as a column or other shapes, and the main control board 121 and the first limiting member 1123 can also be connected and limited by bolts or other means.

[0065] In some embodiments, the base 112 may further include at least one positioning structure 1124. It may be disposed on the base body 1121 and / or the first limiting member 1123 and pass through the main control board 121 to further position the main control board 121.

[0066] In some embodiments, the main control board 121 may be arranged perpendicular to the axis of the housing 11, and at least one positioning hole corresponding to the positioning structure 1124 may be formed in its thickness direction, or a positioning groove may be formed in the side of the main control board 121 away from the opening end of the base 112. The positioning structure 1124 may be protruding and disposed on the first limiting member 1123, and pass through the positioning hole or positioning groove to limit the positioning of the main control board 121.

[0067] It should be understood that the number of the first limiting member 1123 can be greater than or equal to the number of the snap-fit ​​structure 1122 and the positioning structure 1124. The snap-fit ​​structure 1122 and the positioning structure 1124 can be respectively set on different first limiting members 1123, and no specific limitation is made here.

[0068] In some embodiments, the base 112 may further include at least one second limiting member 1125. The second limiting member 1125 is disposed at a position corresponding to the battery receiving cavity 115 on the base 1121, and is used to limit the battery 13.

[0069] In some embodiments, a third limiting member 1134 may be provided on the side of the cover portion 1132 facing the connecting portion 1131, for cooperating with the second limiting member 1125 to limit the battery 13.

[0070] In some embodiments, the two ends of the battery 13 can abut against the end walls of the third limiting member 1134 and the seat 1121 respectively along the axial direction, thereby achieving axial limiting. The second limiting member 1125 is cylindrical and is used to sleeve on the outer periphery of the end of the battery 13 to limit the battery 13 in the circumferential direction.

[0071] In some other alternative embodiments, the second limiting member 1125 may also be configured as a plurality of protrusions located on the end wall or side wall of the seat 1121, which are spaced apart on the outer periphery of the end of the battery 13, and the cooperation between the protrusions and protrusions can also achieve circumferential limiting of the battery 13.

[0072] In some other alternative embodiments, the third limiting member 1134 may also be disposed on the outer periphery of the battery 13 to limit the battery 13 in the circumferential direction. The second limiting member 1125 may abut against the end of the battery 13 to limit the battery 13 in the axial direction in conjunction with the battery casing 113.

[0073] Referring again to Figure 3, in some embodiments, the electrical connection structure may include a first connection electrode 122. This electrode may be disposed on the main control board 121 for electrical connection with the atomizer 20. The first connection electrode 122 may be disposed on the side of the main control board 121 facing the opening of the base 112. Since the main control cavity 1121A is connected to the atomizer receiving cavity 114 through the opening of the base 112, the atomizer 20 can simultaneously achieve electrical connection with the first connection electrode 122 during the assembly of the atomizer 20 into the atomizer receiving cavity 114.

[0074] For example, in some embodiments, the first connection electrode 122 is at least two electrode posts erected on the main control board 121.

[0075] As shown in Figures 2 and 3, in some embodiments, the main control module 12 may also include an airflow sensor 123, which may be mounted on the main control board 121 and electrically connected to the control unit, for sensing changes in the user's suction through negative pressure to control the atomization status of the atomizing component 22 accordingly.

[0076] It should be understood that the airflow sensor 123 can be implemented using existing microphones or MEMS sensors, and no specific limitation is made here.

[0077] In some embodiments, the main control module 12 may further include a terminal block 124, which may be disposed on the main control board 121 and electrically connected to the control unit for connecting an external power source to charge the battery 13.

[0078] In some embodiments, the terminal block 124 may be disposed on the side of the main control board 121 opposite to the opening end of the base 112. A charging port 1121E may also be provided on the end wall of the base 112 away from the opening end. The terminal block 124 may pass through the charging port 1121E for connection to an external power source.

[0079] In some other alternative embodiments, the terminal block 124 may also be located at other locations on the main control board 121, or electrically connected to the control unit via a wire. Correspondingly, the charging port 1121E may also be located at other locations on the housing 11.

[0080] As shown in Figure 2, in some embodiments, the atomizer 20 may include an atomizing shell 21, an atomizing component 22, and a liquid storage component 23. The atomizing shell 21 is detachably inserted into the atomizer receiving cavity 114 along the axial direction of the housing 111 from its first end. The atomizing component 22 and the liquid storage component 23 are disposed within the atomizing shell 21. The liquid storage component 23 stores a liquid matrix. The atomizing component 22 is electrically connected to the main control module 12 and is used to atomize the liquid matrix within the liquid storage component 23.

[0081] Referring to Figures 3 and 4, the shape of the atomizing shell 21 is adapted to the shape of the atomizer receiving cavity 114, so that the sidewall of the atomizing shell 21 fits flush with the cavity wall of the atomizer receiving cavity 114, thus providing guidance during insertion. In some embodiments, the atomizing shell 21 can be configured as various shapes such as cylindrical, polygonal, irregular, disc-shaped, semi-circular, or elliptical, without specific limitations. Of course, the sidewall of the atomizing shell 21 can also be spaced apart from at least a portion of the cavity wall of the atomizer receiving cavity 114.

[0082] In some embodiments, the atomizing housing 21 may include a main body 211, an atomizing nozzle 213, a connecting seat 212, and an electrode guide 214. The connecting seat 212 and the atomizing nozzle 213 may be located axially at opposite ends of the main body 211, together defining a chamber for housing the liquid storage assembly 23 and the atomizing assembly 22. The electrode guide 214 is disposed on the connecting seat 212 for electrically connecting the first connecting electrode 122 to the atomizing assembly 22.

[0083] As shown in Figures 1 and 2, when the atomizer 20 is inserted into the atomizer housing 114, the atomizing nozzle 213 protrudes from the first end of the housing 111, forming an air outlet channel 2131 for the user to inhale. The connector 212 is located inside the atomizer housing 114 near the main control module 12. The electrode guide 214 can be tubular, protruding from the side of the connector 212 away from the main body 211, facing the main control module 12. The connector 212 can have an electrode connection hole 2121 at the position corresponding to the electrode guide 214, through which the electrode guide 214 passes, so that the electrode guide 214 can communicate with the space inside the atomizer housing 21.

[0084] In some embodiments, the number of electrode guide portions 214 can be set to at least two, corresponding to at least two electrode posts of the first connecting electrode 122. The extending direction of the electrode post can be parallel to the axial direction of the housing 111. Since the atomizer 20 is inserted into the atomizer receiving cavity 114 along the axial direction of the housing 111 during assembly, by providing the electrode guide portion 214, the first connecting electrode 122 can be simultaneously inserted into the electrode guide portion 214 during the insertion of the atomizer 20 along the axial direction of the housing 111. After the atomizer 20 is inserted into place, the electrode guide portion 214 can also provide a certain degree of protection for the connected electrode.

[0085] It should be understood that the electrode guide portion 214 can be configured as a circular tube, or as a polygonal tube or other straight tubular structure. In some other optional embodiments, the electrode guide portion 214 can also be composed of multiple ribs to surround the circumference of the electrode post, thereby achieving a guiding function.

[0086] In some embodiments, referring to Figures 3 and 4 together, the outer contour dimension of the end of the atomizing nozzle 213 near the main body 211 is larger than the outer contour dimension of the end of the main body 211 near the atomizing nozzle 213. This dimensional difference allows the outer surface of the atomizing nozzle 213 to smoothly transition with the outer surface of the first end of the housing 111 when the atomizer 20 is inserted into the atomizer receiving cavity 114. This arrangement serves as a limiting mechanism after the atomizer 20 is properly installed, and also improves the aesthetic appearance and smoothness of the outer surface of the electronic atomizing device 1, thereby enhancing the user experience.

[0087] In some embodiments, the outer contour dimension of the body 211 near the atomizing nozzle 213 may be at least partially truncated and slightly larger than the contour dimension of the chamber wall of the atomizer receiving cavity 114. When the atomizing shell 21 is inserted into the atomizer receiving cavity 114, the body 211 may be press-fitted with the chamber wall of the atomizer receiving cavity 114 to improve the stability of the assembly between the two.

[0088] As shown in Figure 4, in some embodiments, the outer shell 11 is further provided with a first air inlet 1121D communicating with the outside, and the atomizing shell 21 is provided with a second air inlet 2122, with the first air inlet 1121D communicating with the second air inlet 2122. The atomizing component 22 also defines an atomizing channel 220, which can be connected to the second air inlet 2122 and the air outlet channel 2131 respectively. During the user's inhalation process, the airflow sequentially passes through the atomizing device 1 from the first air inlet 1121D, the second air inlet 2122, the atomizing channel 220, and the air outlet channel 2131, and carries away the liquid matrix atomized by the atomizing component 22 in the atomizing channel 220 for the user's use.

[0089] In some embodiments, the first air inlet 1121D may be formed on the base 1121 and may communicate with the main control cavity 1121A defined by the base 112. The second air inlet 2122 is formed on the connecting seat 212. Since the connecting seat 212 is located at the end of the atomizer receiving cavity 114 near the main control cavity 1121A, the second air inlet 2122 may communicate with the first air inlet 1121D through the main control cavity 1121A.

[0090] In some other alternative embodiments, the first air inlet 1121D may also be located at other locations on the housing 11, and the second air inlet 2122 may also be located at other locations on the atomizing housing 21.

[0091] As shown in Figures 2 and 3, in some embodiments, the airflow sensor 123 can be disposed on the side of the main control board 121 facing the atomizer housing 114. The connector 212 has a sensor housing 215 on the side facing away from the main body 211, which can accommodate the airflow sensor 123 after the atomizer 20 is inserted into the housing 111.

[0092] The sensor housing 215 defines a negative pressure chamber 2151, which is connected to an airflow channel formed by the first air inlet 1121D, the second air inlet 2122, the atomization channel 220, and the air outlet channel 2131 via the air guide hole 2123. During user inhalation, the airflow passes through the airflow channel and can carry away some of the gas in the negative pressure chamber 2151 through the air guide hole 2123, thereby creating a negative pressure inside the chamber that changes with inhalation. At least a portion of the airflow sensor 123 is located within the negative pressure chamber 2151, and can feed back the detected changes in the negative pressure of the chamber to the control unit, causing it to adjust the atomization control of the atomization component 22 accordingly.

[0093] In some embodiments, when the atomizer 20 is configured to be installed in the atomizer housing 114, the airflow sensor 123 can be installed in conjunction with the atomizer 20, and the two together form a negative pressure chamber 2151.

[0094] In some embodiments, the sensor housing 215 may be generally cylindrical, with its inner contour matching the outer contour of the airflow sensor 123. After the main control module 12 and the atomizer 20 are respectively inserted into place, the sensor housing 215 and the airflow sensor 123 together form a negative pressure chamber 2151, which can detect changes in negative pressure within the chamber.

[0095] In some embodiments, the airflow sensor 123 can also be slightly interference-fitted with the sensor housing 215. This interference fit improves the relative sealing of the negative pressure chamber 2151, thereby increasing the accuracy of the airflow sensor 123. Simultaneously, the interference fit between the airflow sensor 123 and the sensor housing 215 further enhances the stability of the assembly between the atomizer 20 and the atomizing host 10.

[0096] Of course, in some other embodiments, the sensor housing 215 can also be independently constructed as a negative pressure chamber 2151, and the airflow sensor 123 can also be entirely disposed within the negative pressure chamber 2151, communicating with the control unit on the main control board 121 via wireless signal connection, wire connection, or other means. In this embodiment, the sensor housing 215 can also be disposed at any other location through which the airflow channel passes, which will not be listed here one by one.

[0097] As shown in Figure 2, in some embodiments, an air inlet chamber 210 may be defined between the liquid storage component 23 and the connecting seat 212. The air inlet chamber 210 may be connected to the second air inlet 2122 and the atomizing channel 220 respectively, as a component of the airflow channel.

[0098] In some embodiments, the connecting seat 212 may have an air guide hole 2123 that communicates with the negative pressure chamber 2151. The air guide hole 2123 may communicate with the air inlet chamber 210, thereby realizing the negative pressure change in the negative pressure chamber 2151 during the user's suction process.

[0099] As shown in Figure 2, in some embodiments, the atomizing shell 21 may also include an air guide tube 216, which can be inserted into the air inlet chamber 210 and extend to the negative pressure chamber 2151 and the air inlet chamber 210 at both ends, respectively.

[0100] It should be understood that the air duct 216 can be a straight pipe structure with various cross-sectional shapes, or a curved pipe structure with various cross-sectional shapes; no specific limitation is made here.

[0101] It should be understood that the atomizing nozzle 213, the main body 211, and the connecting seat 212 can be detachably or non-detachably connected together by means of threaded connection, bolt connection, adhesive bonding, snap-fit ​​connection, integral molding, etc., without specific limitations. The electrode guide 214, the sensor housing 215, and the air guide tube 216 can be integrally molded on the connecting seat 212.

[0102] As shown in Figure 2, in some embodiments, the liquid storage assembly 23 may include a liquid storage shell 231, which may define a liquid storage cavity 2310 inside. The atomizing assembly 22 may be disposed inside the liquid storage shell 231 for atomizing the liquid matrix inside the liquid storage cavity 2310.

[0103] The sidewall of the liquid storage shell 231 can be spaced apart from the outer shell 11 so that during manufacturing, the gap between the outer shell 11 and the atomizing shell 21 can achieve the effect of heat insulation.

[0104] In some embodiments, the liquid storage assembly 23 may further include a liquid storage element 232, which may be made of a porous material with numerous capillary channels, such as ceramic or cotton structure, and is filled in the liquid storage cavity 2310. The liquid matrix is ​​stored through the internal porous channels.

[0105] In some embodiments, the liquid storage assembly 23 may further include a first liquid absorption member 233 and a second liquid absorption member 234. These can be respectively disposed on the liquid storage shell 231 to absorb leaked liquid matrix, prevent the liquid matrix from leaking along the gaps, and further improve the user experience.

[0106] In some embodiments, the first liquid suction member 233 may be disposed between the liquid storage shell 231 and the atomizing nozzle 213 to prevent the liquid matrix from leaking from the connection between the atomizing chamber 2312 and the air outlet channel 2131. The second liquid suction member 234 may be disposed between the liquid storage shell 231 and the connecting seat 212 to prevent the liquid matrix from leaking from the reserved electrode connection hole 2121.

[0107] In some embodiments, the atomizing assembly 22 may include a liquid guiding element 221, an atomizing element 222, and a second connecting electrode (not shown in the figure). The liquid guiding element 221 is disposed within the liquid storage shell 231 and can be used to conduct the liquid matrix within the liquid storage cavity 2310. The atomizing element 222 is disposed on the liquid guiding element 221 and can atomize the liquid matrix conducted by the surrounding liquid guiding elements 221 after being energized.

[0108] It should be understood that when the liquid storage assembly 23 includes a liquid storage element 232, the liquid guiding element 221 can be disposed adjacent to the liquid storage element 232. The liquid guiding element 221 may have liquid guiding holes to facilitate the conduction of the liquid matrix. Alternatively, the liquid guiding element 221 can also be made of a porous material with capillary channels to achieve liquid conduction and connection through capillary action. When the liquid storage assembly 23 does not include a liquid storage element 232, the liquid guiding element 221 can also be used to separate the liquid storage chamber 2310 and the atomizing chamber 2312.

[0109] The atomizing element 222 can also be in the form of various shapes of sheets and attached to the liquid guiding element 221. It can also be in other shapes such as filament, block, column, etc., and set on the liquid guiding element 221. No specific limitation is made here.

[0110] The second connecting electrode is electrically connected to the atomizing element 222 and is used for electrical connection with the first connecting electrode 122. At least one of the electrodes, the second connecting electrode and the first connecting electrode 122, can pass through the electrode guide portion 214.

[0111] It should be understood that the second connecting electrode can be configured as a lead wire, electrode post, electrode patch, or other structures, and no specific limitation is made here.

[0112] In some embodiments, when both the first connecting electrode 122 and the second connecting electrode are rigid electrical connection structures, at least one elastic buffer structure may be provided between them to absorb accumulated tolerances and improve the stability of the electrical connection.

[0113] In some embodiments, the elastic buffer structure may be an elastic pad, an electrical connection spring with elastic properties, or other structures, without specific limitations.

[0114] In some other alternative embodiments, when the second connecting electrode is configured as a columnar structure and extends from the electrode guide portion 214 to the outside of the atomizing shell 21, the first connecting electrode 122 can also be configured as an electrode patch, conductive bump, conductive hole, or other structure attached to the main control board 121.
