Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and in particular to an electronic atomization device. Background Technology

[0002] Currently, pod-based e-cigarettes mainly fix and seal the cartridges by axial pressing of the mouthpiece. However, since the cartridges are only subject to axial limiting force, when the e-cigarette is subjected to external forces such as drops or impacts, the cartridges inside are prone to displacement, causing air leakage and affecting the user experience. Utility Model Content

[0003] Therefore, it is necessary to provide an electronic atomization device with improved sealing performance to address the aforementioned technical problems.

[0004] An embodiment of this application provides an electronic atomizing device, including an atomizing component and a mouthpiece assembly that can be assembled with the atomizing component along a first direction. One of the mouthpiece assembly and the atomizing component is provided with a first air guide tube, and the other is provided with a sealing element that matches the first air guide tube. The sealing element is provided with a through hole. The first air guide tube is provided with a second extrusion surface that extrudes the sealing element when assembled with the sealing element and a first extrusion surface that extrudes the sealing element along the first direction. The second extrusion surface includes an inclined surface. When the mouthpiece assembly is assembled with the atomizing component along the first direction, the inclined surface intersects with the first direction and at least a portion of the second extrusion surface is embedded in the through hole.

[0005] In one embodiment, both the first extrusion surface and the inclined surface are arranged around the central axis of the first air guide tube, and the first extrusion surface is located on the periphery of the inclined surface.

[0006] In one embodiment, the first extrusion surface includes a plane perpendicular to the central axis of the first air duct, and the inclined surface gradually approaches the central axis of the first air duct along the direction of embedding the seal.

[0007] In one embodiment, the first air guide tube further includes a third extrusion surface and an annular side surface, wherein the third extrusion surface extrudes the seal when the first air guide tube is assembled with the seal, and the third extrusion surface is located on the side of the first extrusion surface opposite to the second extrusion surface.

[0008] In one embodiment, the slope satisfies at least one of the following conditions: the slope length is between 0.3 mm and 1.5 mm; the slope angle is between 15° and 45°; and the slope depth is between 0.2 mm and 1.2 mm.

[0009] In one embodiment, the seal includes a mounting surface for interfering with the first extrusion surface; the mounting surface is configured to be a plane perpendicular to the first direction before the nozzle assembly is assembled onto the atomizing assembly, and is partially deformed by the first extrusion surface and partially deformed by the inclined surface when the nozzle assembly is assembled onto the atomizing assembly.

[0010] In one embodiment, the nozzle assembly includes an air intake and a first air guide tube, and the atomizing assembly includes a reservoir for storing a liquid matrix, an atomizing core for atomizing the liquid matrix to generate an aerosol, and a second air guide tube connected to a seal. The seal is disposed on the atomizing assembly and is used to provide a seal between the first air guide tube and the second air guide tube. The second air guide tube is used to guide the aerosol to the seal, such that the aerosol is introduced into the air intake through the first air guide tube.

[0011] In one embodiment, at least a portion of the second air guide tube is embedded in the through hole; when the nozzle assembly is mounted on the atomizing assembly, the length of the portion of the first air guide tube embedded in the through hole in the first direction is less than the length of the portion of the second air guide tube embedded in the through hole in the first direction.

[0012] In one embodiment, the atomizing assembly further includes a cylinder that encloses a liquid storage chamber and a cover connected to the cylinder, a seal that is connected to the cylinder and the cover, and the seal provides a seal between the cylinder and the cover.

[0013] In one embodiment, the seal is provided with a first pressure balance hole communicating with the liquid storage chamber, and the cover is provided with a second pressure balance hole communicating with the first pressure balance hole.

[0014] In one embodiment, the cover has a drainage hole through which at least a portion of the seal is exposed for connection to the first air duct, and the seal provides a seal between the cover and the second air duct.

[0015] The electronic atomizing device provided in this application has a first extrusion surface and a second extrusion surface on the first air guide tube for extruding the seal. When the nozzle assembly is assembled on the atomizing assembly along the first direction, the first extrusion surface extrudes the seal along the first direction, and the inclined surface on the second extrusion surface extrudes the seal along the inclined direction. This not only increases the sealing area between the second extrusion surface and the seal, but also allows the second extrusion surface to interfere with the seal in other directions. Through the multi-directional and large-area interference between the first air guide tube and the seal, the installation stability and sealing performance of the seal are improved, the probability of air leakage in the electronic atomizing device is reduced, and the user experience is improved.

[0032] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0033] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0034] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0035] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., 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, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0036] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0037] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0038] The electronic atomizing device provided in the embodiments of this application will now be described with reference to the accompanying drawings. It should be noted that the x-direction in the drawings is the first direction. In the drawings, for ease of drawing, the dimensions are not necessarily proportional to the actual dimensions.

[0039] Please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of an electronic atomizing device according to some embodiments of this application. Figure 2 An example is shown. Figure 1 A cross-sectional view of the electronic atomizing device from the perspective of AA. Figure 3 An example is shown. Figure 2 A cross-sectional view of the nozzle assembly.

[0040] like Figures 1 to 3As shown, an embodiment of this application provides an electronic atomizing device 10, including an atomizing component 100 and a mouthpiece assembly 200 that can be assembled with the atomizing component 100 along a first direction (x direction in the figure). One of the mouthpiece assembly 200 and the atomizing component 100 is provided with a first air guide tube 210, and the other is provided with a sealing member 110 that matches the first air guide tube 210. The sealing member 110 has a through hole 111. The first air guide tube 210 has a second extrusion surface 212 that compresses the sealing member 110 when assembled with the sealing member 110, and a first extrusion surface 211 that compresses the sealing member 110 along the first direction x. The second extrusion surface 212 includes an inclined surface. When the mouthpiece assembly 200 is assembled with the atomizing component 100 along the first direction x, the inclined surface intersects with the first direction x, and at least a portion of the second extrusion surface 212 is embedded in the through hole 111.

[0041] The first extrusion surface 211 is neither parallel nor coplanar with the inclined surface, which allows the first air guide tube 210 and the seal 110 to form interference in multiple different directions, which helps to improve the fit stability and connection sealing between the first air guide tube 210 and the seal 110.

[0042] It should be noted that the inclined plane is a surface that is neither parallel to nor perpendicular to the first direction x. In the first direction x, the boundary line of the inclined plane's cross-section can include a straight line, a convex arc, or a concave arc.

[0043] It should be noted that the second extrusion surface 212 includes inclined surfaces that satisfy any of the following conditions: 1. The entire second extrusion surface 212 is inclined. 2. The second extrusion surface 212 surrounds the central axis z of the first air guide tube 210, and in the circumferential direction of the second extrusion surface 212, a portion of the second extrusion surface 212 is inclined, and a portion of the second extrusion surface 212 is non-inclined. The non-inclined surface can be parallel to the first direction x. For example, 80% of the second extrusion surface 212 surrounding the central axis z of the first air guide tube 210 is inclined, and the other 20% is non-inclined. When the second extrusion surface 212 in the circumferential direction is composed of both inclined and non-inclined surfaces, multiple inclined surfaces and multiple non-inclined surfaces can be alternately arranged around the central axis z of the first air guide tube 210, or it can be arranged with only one continuous inclined surface and one continuous non-inclined surface around the central axis z of the first air guide tube 210. 3. The second extrusion surface 212 includes a non-sloping surface that surrounds at least a portion of the central axis z of the first air guide tube 210 and a sloping surface that surrounds at least a portion of the central axis z of the first air guide tube 210. The sloping surface and the non-sloping surface are arranged along the first direction x, and the non-sloping surface may be parallel to the first direction x.

[0044] Optionally, both the first extrusion surface 211 and the inclined surface surround the central axis of the first air guide tube 210. Figure 3The axial direction z of the first air guide tube 210 is arranged such that an annular sealing interference can be formed between the first extrusion surface 211 and the seal 110, and an annular sealing interference can also be formed between the inclined surface and the seal 110. Furthermore, the first extrusion surface 211 is located on the periphery of the inclined surface. When the nozzle assembly 200 is assembled with the atomizing assembly 100 along the first direction x, the central axis z of the first air guide tube 210 is arranged parallel to the first direction x.

[0045] Optionally, the seal 110 may be made of an elastic material such as rubber or silicone, and the seal 110 includes a mounting surface 112 for interfering with the first extrusion surface 211. The mounting surface 112 may be configured to be a plane perpendicular to the first direction x before the nozzle assembly 200 is assembled onto the atomizing assembly 100, and when the nozzle assembly 200 is assembled onto the atomizing assembly 100, it is partially deformed by the first extrusion surface 211 and partially deformed by the inclined surface. It is easy to understand that the first extrusion surface 211 is neither perpendicular nor parallel to the inclined surface. Therefore, when the first air guide tube 210 extrudes the mounting surface 112 along the first direction x, the portion of the mounting surface 112 that is extruded by the first extrusion surface 211 remains a plane perpendicular to the first direction x and is at least partially in contact with the first extrusion surface 211; however, the portion that is extruded by the inclined surface of the second extrusion surface 212 will be deformed into an inclined surface and will be at least partially in contact with the inclined surface of the second extrusion surface 212. Furthermore, because the mounting surface 112 is deformed by the simultaneous compression of the first extrusion surface 211 and the second extrusion surface 212, the sealing element 110 can be firmly attached to the first air guide tube 210 and achieve a sealing function. In other embodiments, before the nozzle assembly 200 is assembled to the atomizing assembly 100, at least a portion of the mounting surface 112 is neither perpendicular nor parallel to the first direction x.

[0046] The electronic atomizing device 10 of this application embodiment has a first extrusion surface 211 and a second extrusion surface 212 on the first air guide tube 210 for extruding the sealing member 110. When the nozzle assembly 200 is assembled on the atomizing assembly 100 along the first direction x, the first extrusion surface 211 extrudes the sealing member 110 along the first direction x, and the inclined surface on the second extrusion surface 212 extrudes the sealing member 110 along the inclined direction (the direction intersecting with the first direction x). This not only increases the sealing area between the second extrusion surface 212 and the sealing member 110, but also allows the second extrusion surface 212 to interfere with the sealing member 110 in other directions. Through the multi-directional and large-area interference between the first air guide tube 210 and the sealing member 110, the installation stability and sealing performance of the sealing member 110 are improved, the probability of air leakage of the electronic atomizing device 10 is reduced, and the user experience is improved.

[0047] like Figure 3As shown, in some embodiments, the first extrusion surface 211 includes a plane perpendicular to the central axis z of the first air guide tube 210. The inclined surface of the second extrusion surface 212 gradually approaches the central axis z of the first air guide tube 210 along the direction of embedding the seal 110.

[0048] It is easy to understand that, since the plane of the first extrusion surface 211 is perpendicular to the central axis z, when the atomizing assembly 100 and the nozzle assembly 200 are assembled along the first direction x, the first extrusion surface 211 is perpendicular to the first direction x, thereby allowing the plane of the first extrusion surface 211 to press the mounting surface 112 on the seal 110 along the first direction x, achieving an axial (parallel to the central axis z of the first air guide tube) sealing connection between the seal 110 and the first air guide tube 210. Furthermore, since the inclined surface of the second extrusion surface 212 gradually approaches the central axis z of the first air guide tube 210 along the direction of embedding into the seal 110, when the atomizing assembly 100 and the nozzle assembly 200 are assembled along the first direction x, the inclined surface of the second extrusion surface 212 can guide part of the second extrusion surface 212 into the through hole 111, improving the installation accuracy of the atomizing assembly 100 and the nozzle assembly 200. After the atomizing component 100 and the nozzle component 200 are assembled, the part of the mounting surface 112 that is deformed by the inclined surface compression obliquely surrounds and wraps the inclined surface, applying a radial force (in the direction intersecting the central axis z of the first air guide tube 210) to the second compression surface 212, thereby achieving a radial sealing connection between the sealing component 110 and the first air guide tube 210, while reducing the probability of radial misalignment of the first air guide tube 210, and further improving the installation stability and sealing performance of the sealing component 110.

[0049] It should be noted that the axial direction mentioned above refers to the direction parallel to the central axis z of the first air guide tube 210, and the radial direction refers to the direction that passes through the central axis z of the first air guide tube 210 and intersects with the axial direction. When the atomizing assembly 100 and the nozzle assembly 200 are assembled along the first direction x, the first direction x can be regarded as the direction parallel to the axial direction.

[0050] The electronic atomizing device 10 of some embodiments of this application achieves an axially sealed connection between the sealing member 110 and the first air guide tube 210 when the atomizing assembly 100 and the mouthpiece assembly 200 are assembled along the first direction x by making the first extrusion surface 211 include a plane perpendicular to the central axis z of the first air guide tube 210. By making the inclined surface of the second extrusion surface 212 gradually approach the central axis z of the first air guide tube 210 along the direction of embedding the sealing member 110, the installation accuracy of the atomizing assembly 100 and the mouthpiece assembly 200 is improved, while the radial sealing connection between the sealing member 110 and the first air guide tube 210 is achieved, reducing the probability of radial misalignment of the first air guide tube 210, and further improving the installation stability and sealing performance of the sealing member 110.

[0051] Please refer to Figure 3 and Figure 4 , Figure 4 An example is shown. Figure 3 A magnified view of the nozzle component at position B.

[0052] like Figure 3 and Figure 4 As shown, in some embodiments, the first air guide tube 210 further includes a third extrusion surface 213 and an annular side surface 214. The third extrusion surface 213 extrudes the seal 110 when the first air guide tube 210 is assembled with the seal 11. The third extrusion surface 213 is located on the side of the first extrusion surface 211 that is away from the second extrusion surface 212.

[0053] The annular side surface 214 refers to at least a portion of the outer peripheral surface of the first air guide tube 210, and the third extrusion surface 213 is located between the annular side surface 214 and the first extrusion surface 211.

[0054] Furthermore, the third extrusion surface 213 includes a chamfer on the first air guide tube 210 between the annular side surface 214 and the first extrusion surface 211. The chamfer on the third extrusion surface 213 satisfies any of the following conditions: 1. All of the third extrusion surfaces 213 are chamfered, so that the annular side surface 214 and the first extrusion surface 211 have a chamfer surrounding the central axis z of the first air guide tube 210. 2. Part of the third extrusion surface 213 is chamfered, so that the chamfer does not reach 360° around the central axis z of the first air guide tube 210. The chamfer can be a rounded corner or a beveled corner.

[0055] Optionally, when the atomizing assembly 100 and the nozzle assembly 200 are assembled along the first direction x, the third extrusion surface 213 extrudes the mounting surface 112, causing a portion of the mounting surface 112 to deform and fit against the third extrusion surface 213. Further, the deformed mounting surface 112 is recessed so that at least a portion of the third extrusion surface 213 can be circumferentially surrounded by the mounting surface 112.

[0056] Optionally, the chamfer on the third extrusion surface 213 gradually approaches the central axis z of the first air guide tube 210 along the assembly direction of the atomizing assembly 100 and the nozzle assembly 200. Furthermore, the slope angle of the chamfer on the third extrusion surface 213 can be the same as the slope angle of the inclined surface of the second extrusion surface 212.

[0057] The electronic atomizing device 10 of some embodiments of this application provides a third extrusion surface 213 on the first air guide tube 210, located between the annular side surface 214 and the first extrusion surface 211. The third extrusion surface 213 and the second extrusion surface 212 have a synergistic effect, which further reduces the probability of radial misalignment of the first air guide tube 210, thereby further improving the installation stability and sealing performance of the seal 110.

[0058] In some embodiments, the inclined surface of the second extrusion surface 212 satisfies at least one of the following conditions:

[0059] The slope length of the inclined plane ( Figure 4 Dimension C) is between 0.3mm and 1.5mm;

[0060] The slope angle of the inclined plane ( Figure 4 The dimension θ in the middle is between 15° and 45°;

[0061] and, the slope depth of the slope ( Figure 4 Dimension B) is between 0.2mm and 1.2mm.

[0062] It is easy to understand that the slope length C of the inclined plane determines the contact area between the second pressing surface 212 and the seal 110; the larger the slope length C, the larger the contact area between the second pressing surface 212 and the seal 110. The slope angle θ of the inclined plane determines the magnitude of the radial force exerted by the inclined plane on the seal 110; the larger the slope angle θ, the larger the radial force exerted by the inclined plane on the mounting surface 112 and / or the through hole 111. The slope depth B of the inclined plane determines the depth to which the inclined plane is embedded in the through hole 111 or the depth to which the mounting surface 112 is deformed due to pressing; the larger the slope depth B, the deeper the inclined plane is embedded in the through hole 111 or the deeper it is pressed on the mounting surface 112.

[0063] Please refer to Figures 1 to 5 , Figure 5 A schematic diagram of an example suction nozzle assembly is shown.

[0064] like Figures 1 to 5 As shown, in some embodiments, a first air guide tube 210 is disposed on a nozzle assembly 200, which also includes an air intake 220. A seal 110 is disposed on an atomizing assembly 100, which further includes a liquid reservoir 120 for storing a liquid matrix, an atomizing core 130 for atomizing the liquid matrix to generate an aerosol, and a second air guide tube 140 connected to the seal 110. The seal 110 provides a seal between the first air guide tube 210 and the second air guide tube 140, and the second air guide tube 140 guides the aerosol to the seal 110, such that the aerosol is introduced into the air intake 220 through the first air guide tube 210.

[0065] The second air guide tube 140 connects the atomizing core 130 and the through hole 111 on the sealing member 110. The end of the first air guide tube 210 facing away from the first extrusion surface 211 is connected to the air intake 220. When the atomizing assembly 100 and the mouthpiece assembly 200 are assembled along the first direction x, at least a portion of the second extrusion surface 212 is embedded in the through hole 111, so that the atomized mist at the atomizing core 130 can be sequentially guided to the air intake 220 through the second air guide tube 140, the through hole 111 on the sealing member 110, and the first air guide tube 210.

[0066] Optionally, the liquid matrix can be stored directly in the storage chamber 120, or it can be stored in the storage chamber 120 in the form of a cartridge, oil-absorbing cotton, etc. The storage chamber 120 is an annular cavity that surrounds the second air guide tube 140 and the atomizing core 130, and the central axis of the annular cavity coincides with the central axis of the second air guide tube 140.

[0067] Optionally, at least a portion of the second air guide tube 140 is embedded in the through hole 111. When the nozzle assembly 200 is assembled onto the atomizing assembly 100, the length of the portion of the first air guide tube 210 embedded in the through hole 111 in the first direction x is less than the length of the portion of the second air guide tube 140 embedded in the through hole 111 in the first direction x. It is readily understood that before the nozzle assembly 200 is assembled with the atomizing assembly 100, the seal 110 is first assembled with the second air guide tube 140, and the second air guide tube 140 is partially embedded in the through hole 111, with a relatively deep embedding depth. This is to improve the stability of the seal 110 when the nozzle assembly 200 is assembled with the atomizing assembly 100, preventing the seal 110 from shifting when the first air guide tube 210 compresses it, thereby reducing the risk of air leakage.

[0068] In some embodiments of the electronic atomizing device 10 of this application, when the nozzle assembly 200 is assembled onto the atomizing assembly 100, both the first air guide tube 210 and the second air guide tube 140 are partially embedded in the through hole 111, so that the first air guide tube 210 can be connected with the second air guide tube 140 to conduct aerosol. At the same time, the sealing performance of the sealing member 110 to the first air guide tube 210 and the second air guide tube 140 is improved, the risk of air leakage is reduced, and the liquid matrix in the liquid storage chamber 120 can also be prevented from leaking into the first air guide tube 210 and the second air guide tube 140. By ensuring that when the mouthpiece assembly 200 is assembled onto the atomizing assembly 100, the length of the portion of the first air guide tube 210 embedded in the through hole 111 in the first direction x is less than the length of the portion of the second air guide tube 140 embedded in the through hole 111 in the first direction x, it is convenient to assemble and connect the mouthpiece assembly 200 and the atomizing assembly 100, and also convenient to separate the mouthpiece assembly 200 from the atomizing assembly 100 for replacement of the atomizing assembly 100.

[0069] Please refer to Figure 2 , Figure 6 , Figure 7 and Figure 8 , Figure 6 A schematic diagram of an example atomizing component is provided. Figure 7 A schematic diagram of an example atomizing component is provided. Figure 8 An example is shown. Figure 2 A magnified view of the electronic atomizing device at position C.

[0070] like Figure 2 , Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, the atomizing assembly 100 further includes a cylinder 150 that encloses to form a liquid storage chamber 120 and a cover 160 connected to the cylinder 150, a seal 110 connected to the cylinder 150 and the cover 160, and the seal 110 provides a seal between the cylinder 150 and the cover 160.

[0071] Optionally, the sealing element 110 is provided with a first pressure balance hole 113 communicating with the liquid storage chamber 120, and the cover 160 is provided with a second pressure balance hole 161 communicating with the first pressure balance hole 113. The liquid storage chamber 120 can communicate with the external environment through the first pressure balance hole 113 and the second pressure balance hole 161, and realize the balance of the air pressure inside and outside the liquid storage chamber 120, so that the liquid matrix in the liquid storage chamber 120 can flow smoothly into the atomizing core 130 for atomization and prevent the liquid matrix in the liquid storage chamber 120 from leaking through the atomizing core 130.

[0072] Optionally, the cover 160 is provided with a drain hole 162, through which at least a portion of the seal 110 is exposed for connection with the first air duct 210, and the seal 110 provides a seal between the cover 160 and the second air duct 140. At least a portion of the mounting surface 112 of the seal 110 is exposed from the drain hole 162.

[0073] Please refer to Figure 1 , Figure 2 and Figure 9 , Figure 9 An example is shown. Figure 2 A magnified view of the electronic atomizing device at position D.

[0074] As shown in the figure Figure 2 and Figure 9 As shown, in some embodiments, the electronic atomizing device 10 further includes a base assembly 300, which includes a housing 310 and a battery cell 320. The housing 310 encloses a receiving cavity 311. Both the atomizing assembly 100 and the battery cell 320 are located within the receiving cavity 311, and are arranged along the axial direction of the receiving cavity 311. The axial direction of the receiving cavity 311 is parallel to the axial direction of the second air guide tube 140.

[0075] The battery cell 320 supplies power to the atomizing core 130, enabling the atomizing core 130 to heat up and atomize the liquid matrix. A first electrode 321 is located on the side of the battery cell 320 facing the atomizing assembly 100, and a second electrode 170, electrically connected to the atomizing core 130, is located on the side of the atomizing assembly 100 away from the cover 160. When the atomizing assembly 100 is located within the receiving cavity 311 and the second electrode 170 abuts against the first electrode 321, the battery cell 320 is electrically connected to the atomizing core 130, thus enabling the battery cell 320 to supply power to the atomizing core 130.

[0076] Optionally, the atomizing component 100, the mouthpiece assembly 200, and the base assembly 300 are all detachably connected. When the atomizing component 100 is placed in the receiving cavity 311 and the mouthpiece assembly 200 is assembled with the atomizing component 100, the mouthpiece assembly 200 is simultaneously connected to the outer shell 310 and seals the receiving cavity 311. At this time, the atomizing component 100 is axially limited on both sides in the first direction x by the battery cell 320 and the sealing member 110, respectively, effectively reducing the probability of the atomizing component 100 shaking in the receiving cavity 311, while improving the stability of the power supply from the battery cell 320 to the atomizing core 130 and the sealing performance of the sealing member 110. When the liquid matrix in the atomizing component 100 is used up, the mouthpiece assembly 200 can be separated from the outer shell 310 to allow the atomizing component 100 in the receiving cavity 311 to leak out for easy replacement of the atomizing component 100. After the atomizing component 100 is replaced, the nozzle component 200 is connected to the housing 310 and the receiving cavity 311 is sealed, so that the seal 110 can provide a seal between the first air guide tube 210 and the second air guide tube 140.

[0077] Of course, in other embodiments, the atomizing component 100 can also be a reusable product. When it is necessary to replenish the liquid matrix, the atomizing component 100 can be removed and the cartridge replaced or the liquid matrix can be directly injected into the liquid storage chamber 120.

[0078] Optionally, an air passage 330 extending axially along the receiving cavity 311 is formed between the outer shell 310 and the battery cell 320. When the atomizing assembly 100 abuts against the battery cell 320, the atomizing core 130 communicates with the air passage 330. The outer shell 310 has an air inlet 312 on the side opposite to the mouthpiece assembly 200, which communicates with the air passage 330. When both the atomizing assembly 100 and the mouthpiece assembly 200 are installed with the base assembly 300, air can enter the atomizing core 130 through the air inlet 312 and the air passage 330 in sequence, mix with the atomized aerosol at the atomizing core 130, and then pass through the second air guide tube 140, the through hole 111 and the first air guide tube 210 in sequence before leaving the electronic atomizing device 10 through the air inlet 220.

[0079] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this application.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
