DETAILED DESCRIPTION

[0029] The present application will be further described below in conjunction with the drawings and examples. It is particularly pointed out that the following examples are only for illustrating the present application, but not for limiting the scope of the present application. Similarly, the following examples are only part of the examples of the present application, but not all the examples of the present application, and all other examples obtained by those skilled in the art without making creative efforts are within the scope of protection of the present application.

[0030] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0031] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of the atomizing device 10 provided in the embodiments of this application. Figure 2 yes Figure 1 A schematic diagram of the exploded structure of the atomizing device 10. Figure 3 yes Figure 1 A schematic diagram of the cross-sectional structure of the atomizing device 10 along line V-V.

[0032] The atomizing device 10 provided in this embodiment can contain a substrate to be atomized and can heat the substrate to be atomized to form an aerosol. For example, the atomizing device 10 can be an electronic cigarette, and the substrate to be atomized can be an e-liquid containing extracts of tobacco plants, a cooling liquid that provides an icy sensation, or a chemically synthesized substance. Alternatively, the substrate to be atomized can be an atomizing liquid containing extracts of other herbal plants with practical value (such as medicinal uses), and the atomizing device 10 can be a suction device for atomizing the aforementioned atomizing liquid. Of course, the types of atomizing device 10 and substrate to be atomized are not limited to these, and will not be elaborated on in this embodiment.

[0033] like Figures 1 to 2 As shown, the atomizing device 10 may include: a housing assembly 100, a liquid storage assembly 200, a heating assembly 300, and a control assembly 400. The housing assembly 100 can accommodate various functional components required by the atomizing device 10 and is designed for user gripping. The liquid storage assembly 200 is disposed within the housing assembly 100 and can form a liquid storage cavity together with the housing assembly 100. A portion of the structure of the liquid storage assembly 200 can be disposed within this liquid storage cavity to accommodate the substrate to be atomized. The heating assembly 300 can be disposed within the liquid storage assembly 200 and can heat the substrate to be atomized, causing the substrate to atomize and form an aerosol. The control assembly 400 is also disposed within the housing assembly 100 and is electrically connected to the heating assembly 300 to control the operation of the heating assembly 300. With this configuration, the housing assembly 100 can not only serve as the outer shell of the atomizing device 10, but can also be reused as a liquid storage shell (forming a liquid storage cavity) to accommodate the substrate to be atomized, thereby simplifying the structure of the atomizing device 10 and reducing the material cost of the atomizing device 10.

[0034] The housing assembly 100 has a cavity 101 for accommodating various structural components required for mounting the atomization device 10, and part of the cavity 101 can jointly form a liquid storage cavity with the liquid storage assembly 200 to accommodate the substrate to be atomized. As shown in Figures 2 to 3 The housing assembly 100 can include a top shell 110 and a bottom cover 120. The top shell 110 can be used for hand holding, and the bottom cover 120 is connected to the top shell 110 and can jointly form the cavity 101 with the top shell 110. Meanwhile, the part of the top shell 110 away from the bottom cover 120 can jointly form a first cavity 1011 (i.e., the aforementioned liquid storage cavity, hereinafter referred to as the first cavity 1011) with the liquid storage assembly 200, and the part of the top shell 110 close to the bottom cover 120 can jointly form a second cavity 1012 with the bottom cover 120 and the liquid storage assembly 200. In addition, the top shell 110 and the bottom cover 120 can be assembled by means of non-detachable connection such as bonding or clamping. Of course, the top shell 110 and the bottom cover 120 can also be assembled by means of detachable connection, which is not limited in the present embodiment.

[0035] Further, the top shell 110 has a top wall 111 and a side wall 112 connected thereto, and the side wall 112 can be arranged around the periphery of the top wall 111. The bottom cover 120 can be connected to the part of the side wall 112 away from the top wall 111 and arranged opposite and spaced apart from the top wall 111 to jointly form the cavity 101 with the top wall 111 and the side wall 112. Meanwhile, the top wall 111, the liquid storage assembly 200, and the part of the side wall 112 close to the top wall 111 can jointly form the first cavity 1011, and the bottom cover 120, the liquid storage assembly 200, and the part of the side wall 112 close to the bottom cover 120 can jointly form the second cavity 1012. In the present embodiment, the user can hold the side wall 112 and can perform suction on the atomization device 10 from one side of the top wall 111. That is, the suction direction X of the atomization device 10 can be the direction in which the top wall 111 is away from the bottom cover 120.

[0036] In some embodiments, the structure of the housing assembly 100 can also be adaptively adjusted according to design requirements, as long as the housing assembly 100 has a cavity 101 and can be assembled with various structural components required for the atomization device 10, which is not limited in the present embodiment.

[0037] Please refer to Figure 3 Please refer to Figures 4 to 7 , Figure 4 is Figure 3 the enlarged view of part A in FIG. 1, Figure 5 is Figure 2 the structural view of the mouthpiece assembly 500 in FIG. 1, Figure 6 is Figure 3 the enlarged view of part B in FIG. 1, Figure 7 is Figure 2A structural schematic diagram of the air mixing assembly 600.

[0038] In order to guide the aerosol formed by atomizing the substrate to be atomized out of the first cavity 1011, the shell assembly 100 can also be provided with an air outlet hole 1101 communicating with the first cavity 1011. As shown in Figures 3 to 4 Since the user can inhale the atomization device 10 from the side of the top wall 111, the air outlet hole 1101 can be provided on the top wall 111 of the top shell 110 and can penetrate the top wall 111 in the inhalation direction X to communicate the external atmosphere with the first cavity 1011. At the same time, when the user inhales from the side of the top wall 111, the aerosol formed by atomizing in the first cavity 1011 can be guided out of the first cavity 1011 through the air outlet hole 1101. In addition, the air outlet hole 1101 can be a circular hole, or other regular or irregular shaped hole, which is not limited in the embodiment.

[0039] In some embodiments, the air outlet hole 1101 can not be limited to being provided on the top wall 111 of the top shell 110. For example, when the user inhales the atomization device 10 from the side of the side wall 112, the air outlet hole 1101 can also be provided on the side wall 112 of the top shell 110. That is, the position of the air outlet hole 1101 can be adjusted according to the inhalation position of the atomization device 10, as long as the air outlet hole 1101 can communicate the first cavity 1011 with the external atmosphere to guide the aerosol in the first cavity 1011, which is not limited in the embodiment.

[0040] In order to be able to inject the substrate to be atomized into the first cavity 1011 for the liquid storage assembly 200 to absorb and contain, the shell assembly 100 can also be provided with a liquid injection hole 1102 communicating with the first cavity 1011. As shown in Figures 3 to 4 The liquid injection hole 1102 can be provided on the top wall 111 of the top shell 110 and adjacent to the air outlet hole 1101, and the liquid injection hole 1102 can penetrate the top wall 111 in the inhalation direction X to communicate the external atmosphere with the first cavity 1011. At the same time, the production personnel can inject the substrate to be atomized into the first cavity 1011 through the liquid injection hole 1102, so that the liquid storage assembly 200 absorbs the substrate to be atomized, thereby completing the containing of the substrate to be atomized by the liquid storage assembly 200. In addition, the liquid injection hole 1102 can be a circular hole, or other regular or irregular shaped hole, which is not limited in the embodiment.

[0041] In some embodiments, the liquid injection hole 1102 can also not be limited to being formed on the top wall 111 of the top shell 110. For example, the liquid injection hole 1102 can also be formed on the side wall 112 of the top shell 110 and arranged away from the air outlet hole 1101. That is, the position of the liquid injection hole 1102 can be adaptively adjusted according to design requirements, as long as the liquid injection hole 1102 can communicate the first cavity 1011 with the external atmosphere, so that the production personnel can inject the to-be-atomized substrate into the first cavity 1011 through the liquid injection hole 1102, which is not limited in the present embodiment.

[0042] In some embodiments, the number of liquid injection holes 1102 can also be multiple, so as to improve the efficiency of injecting the to-be-atomized substrate into the first cavity 1011. For example, the number of liquid injection holes 1102 can be two, and the two liquid injection holes 1102 are both formed on the top wall 111 of the top shell 110 and respectively located on the opposite sides of the air outlet hole 1101. The production personnel can inject the to-be-atomized substrate into the first cavity 1011 through the two liquid injection holes 1102 at the same time, so as to improve the injection efficiency of the to-be-atomized substrate. Of course, the number of liquid injection holes 1102 can also be three, four, five or more, and the multiple liquid injection holes 1102 can also not be limited to being formed on the top wall 111 of the top shell 110, which is not limited in the present embodiment.

[0043] In order to facilitate the user to draw and shield the liquid injection hole 1102, the atomization device 10 can further include a suction mouth assembly 500. As shown in Figures 3 to 5 The suction mouth assembly 500 can be arranged on the side of the top shell 110 (top wall 111) away from the bottom cover 120, and the orthographic projection of the suction mouth assembly 500 on the top shell 110 (top wall 111) can also be arranged around the air outlet hole 1101 and can communicate the air outlet hole 1101 with the external atmosphere. At the same time, the user can draw the atomization device 10 by mouth-holding the suction mouth assembly 500, and the aerosol in the first cavity 1011 can be guided out through the air outlet hole 1101 and the suction mouth assembly 500 under the user's suction. In addition, since the liquid injection hole 1102 is arranged adjacent to the air outlet hole 1101, the suction mouth assembly 500 can also cover the liquid injection hole 1102 to avoid the liquid injection hole 1102 being exposed outside the shell assembly 100. In this way, the convenience of the user drawing the atomization device 10 can be improved by using the suction mouth assembly 500, and the liquid injection hole 1102 can also be plugged and hidden by using the suction mouth assembly 500.

[0044] Further, the mouthpiece assembly 500 can include a liquid blocking member 510 and an air guiding member 520. The liquid blocking member 510 can be arranged on the side of the top shell 110 away from the bottom cover 120, i.e. the side of the top wall 111 away from the bottom cover 120, and can cover the liquid injection hole 1102 formed on the top wall 111. The liquid blocking member 510 can absorb and contain the to-be-atomized substrate leaking from the liquid injection hole 1102, so as to seal and hide the liquid injection hole 1102. The air guiding member 520 can be connected with the top wall 111 of the top shell 110 and can cover the liquid blocking member 510, so that the liquid blocking member 510 can be hidden in the air guiding member 520. At the same time, the air guiding member 520 can also be used for the user to suck by mouth, and the orthographic projection of the air guiding member 520 and the liquid blocking member 510 on the top wall 111 of the top shell 110 is arranged around the air outlet hole 1101, so as to communicate the air outlet hole 1101 with the external atmosphere.

[0045] In some embodiments, in order to reduce the protrusion height of the mouthpiece assembly 500 on the shell assembly 100, the side of the top shell 110 away from the bottom cover 120, i.e. the top wall 111, also has a containing groove 1103, and the air outlet hole 1101 and the liquid injection hole 1102 are both formed on the bottom wall of the containing groove 1103. The liquid blocking member 510 can be arranged in the containing groove 1103, the air guiding member 520 is arranged on the side of the liquid blocking member 510 away from the bottom wall of the containing groove 1103, and part of the air guiding member 520 is connected with the side wall of the containing groove 1103 (such as clamping, etc.) and arranged around the liquid blocking member 510. In this way, the protrusion height of the mouthpiece assembly 500 on the top wall 111 can be reduced by using the containing groove 1103, and the liquid blocking member 510 and the liquid injection hole 1102 can be hidden in the containing groove 1103.

[0046] In some embodiments, the design of the mouthpiece assembly 500 can also be omitted, and the user can directly suck by mouth the top shell 110, and the liquid injection hole 1102 can be formed on other positions of the top shell 110 and sealed by other structural members. For example, part of the top wall 111 where the air outlet hole 1101 is formed is locally protruded and forms a structure similar to a volcano, so as to be sucked by mouth by the user, and the liquid injection hole 1102 can be formed on the side wall 112 and sealed by a structure such as a sealing plug.

[0047] In order to form an air flow to carry the aerosol in the first cavity 1011 out when the user sucks, the shell assembly 100 can also be provided with an air inlet hole 1104. For example, Figure 3 and Figure 6As shown, the air inlet hole 1104 can be formed on the side of the bottom cover 120 away from the top wall 111 and penetrates the bottom cover 120 in the air suction direction X to communicate the external atmosphere and the second cavity 1012. Meanwhile, when the user sucks the air through the air guide 520, the air can enter the second cavity 1012 from the air inlet hole 1104, enter the first cavity 1011 from the second cavity 1012, and finally form an air flow to carry out the aerosol formed in the first cavity 1011. In addition, the air inlet hole 1104 can be a circular hole, or other regular or irregular shaped hole, which is not limited in the embodiment.

[0048] In some embodiments, the air inlet hole 1104 can also not be limited to being formed on the bottom cover 120. For example, the air inlet hole 1104 can also be formed on the side wall 112 of the top shell 110. That is, the position of the air inlet hole 1104 can be adaptively adjusted according to design requirements, as long as the air inlet hole 1104 can communicate the second cavity 1012 and the external atmosphere, which is not limited in the embodiment. Meanwhile, in some embodiments, the number of air inlet holes 1104 can be multiple, such as two, three, four or more, to improve the air intake of the atomization device 10.

[0049] In order to control the air intake of the air inlet hole 1104, the atomization device 10 can further include an air regulating assembly 600. As shown, Figures 6 to 7 As shown, the air regulating assembly 600 can be slidably arranged on the side of the bottom cover 120 away from the top wall 111 and can close or open the air inlet hole 1104. For example, the user can slide the air regulating assembly 600 on the bottom cover 120 and make the air regulating assembly 600 slide to the position of the air inlet hole 1104 to cover the air inlet hole 1104 with the air regulating assembly 600, thereby closing the air inlet hole 1104. Similarly, the user can slide the air regulating assembly 600 in the opposite direction on the bottom cover 120 to make the air regulating assembly 600 move away from the position of the air inlet hole 1104, thereby opening the air inlet hole 1104. Of course, the user can also slide the air regulating assembly 600 to partially cover or move away from the air inlet hole 1104 to semi-close or semi-open the air inlet hole 1104, thereby adjusting the air intake of the air inlet hole 1104. In addition, the air regulating assembly 600 can be electrically connected to the control assembly 400 to trigger an electrical signal for the control assembly 400 to receive after sliding, and the control assembly 400 can control the atomization device 10 to realize the corresponding function according to the electrical signal triggered by the air regulating assembly 600.

[0050] Specifically, the air regulating assembly 600 can include a sliding member 610. As shown, Figures 6 to 7As shown, the bottom cover 120 is provided with a sliding groove 121 on the side away from the top wall 111, and the air inlet hole 1104 is provided on the bottom wall of the sliding groove 121, and the sliding piece 610 is slidably arranged in the sliding groove 121 (driven by the user) and can close or open the air inlet hole 1104 after sliding. At the same time, the bottom wall of the sliding groove 121 can also be provided with a through groove 122 communicating with the second cavity 1012, and the sliding piece 610 also has a buckle part 611 penetrating through the through groove 122, and the buckle part 611 can slide in the through groove 122 with the sliding piece 610, and can be connected with the side of the bottom cover 120 facing the top wall 111, to prevent the sliding piece 610 from coming out of the sliding groove 121. It can be understood that the sliding connection between the sliding piece 610 and the bottom cover 120 can also have many ways, which will not be described here.

[0051] Further, the air adjusting assembly 600 can also include a sealing piece 620. As shown, Figures 6 to 7 The sealing piece 620 is arranged between the sliding piece 610 and the bottom wall of the sliding groove 121, and abuts with the sliding piece 610 and the bottom wall of the sliding groove 121 respectively, to fill the gap between the sliding piece 610 and the bottom wall of the sliding groove 121, thereby improving the sealing performance of the atomization device 10. At the same time, the sealing piece 620 is also connected with the sliding piece 610 and can slide in the sliding groove 121 with the sliding piece 610, and the sealing piece 620 can also rub against the bottom wall of the sliding groove 121, to provide a damping feeling for the user to slide the sliding piece 610. The sealing piece 620 can be made of elastic materials such as silica gel, rubber or soft plastic.

[0052] Further, the air adjusting assembly 600 can also include a contact piece 630. As shown, Figures 6 to 7 One end of the contact piece 630 can be connected with the sliding piece 610, and the other opposite end can penetrate through the through groove 122 and extend into the second cavity 1012 to slide with the control assembly 400. When the sliding piece 610 slides in the sliding groove 121, the contact piece 630 can slide on the control assembly 400 with the sliding piece 610, to trigger corresponding electrical signals for the control assembly 400 to receive, and the control assembly 400 can control the atomization device 10 to realize corresponding functions according to the electrical signals triggered by the contact piece 630.

[0053] For example, when the sliding piece 610 slides to the position of opening the air inlet hole 1104, the contact piece 630 can trigger a first electrical signal for the control assembly 400 to receive, and the control assembly 400 can turn on the pneumatic sensor 430 according to the first electrical signal, to detect whether the user has a suction action. Similarly, when the sliding piece 610 slides to the position of closing the air inlet hole 1104, the contact piece 630 can trigger a second electrical signal for the control assembly 400 to receive, and the control assembly 400 can turn off the pneumatic sensor 430 according to the second electrical signal, to save the power of the atomization device 10.

[0054] Please combine Figure 3 See Figures 8 to 10 , Figure 8 yes Figure 3 A magnified view of a portion of point C in the middle. Figure 9 yes Figure 8 A schematic diagram of the structure of the mounting bracket 210. Figure 10 yes Figure 8 A schematic diagram of the connection structure between the mounting bracket 210 and the liquid storage fiber 220.

[0055] The liquid storage component 200 can be configured together with the housing component 100 to form a first cavity 1011, and a portion of the structure of the liquid storage component 200 can also be disposed within the first cavity 1011 to accommodate the substrate to be atomized. Figure 3 and Figure 8 As shown, the liquid storage assembly 200 may include a mounting bracket 210 and a liquid storage fiber 220. The mounting bracket 210 may be disposed within the cavity 101 and may divide the cavity 101 into a first cavity 1011 and a second cavity 1012 that are interconnected. The first cavity 1011 is located on the side of the mounting bracket 210 facing away from the bottom cover 120, while the second cavity 1012 is located between the mounting bracket 210 and the bottom cover 120. The liquid storage fiber 220 may be disposed within the first cavity 101, and at least a portion of the liquid storage fiber 220 may abut against the cavity wall of the first cavity 1011 corresponding to the top shell 110, and may be used to contain the substrate to be atomized. In this embodiment, the mounting bracket 210 can cooperate with the top shell 110 to form a first cavity 1011 for accommodating the liquid storage fiber 220, and can cooperate with the top shell 110 and the bottom cover 120 to form a second cavity 1012 for accommodating the control component 400. This allows the top shell 110 to not only serve as the outer shell of the atomizing device 10, but also to be reused as a liquid storage shell for accommodating the liquid storage fiber, thereby simplifying the structure of the atomizing device 10 and reducing the material cost of the atomizing device 10.

[0056] The mounting bracket 210 is disposed within the cavity 101 and can divide the cavity 101 into a first cavity 1011 and a second cavity 1012 that are connected. For example... Figure 3 and Figures 8 to 9As shown, the mounting bracket 210 can be connected with the side wall 112 of the top shell 110, and can be arranged opposite and spaced apart from the top wall 111 and the bottom cover 120 respectively. Meanwhile, the mounting bracket 210 can jointly enclose the first cavity 1011 with the top wall 111 and the part of the side wall 112 away from the bottom cover 120, and can jointly enclose the second cavity 1012 with the bottom cover 120 and the part of the side wall 112 close to the bottom cover 120. In addition, the central region of the mounting bracket 210 can be provided with a ventilation hole 2101, and the ventilation hole 2101 can penetrate the mounting bracket 210 in the inhalation direction X to communicate the first cavity 1011 and the second cavity 1012. In this way, when the user inhales, air can enter the second cavity 1012 from the air inlet hole 1104, enter the first cavity 1011 from the ventilation hole 2101, and then be discharged from the first cavity 1011 to form an air flow to carry away the aerosol in the first cavity 1011.

[0057] Further, in order to reduce the probability of the aerosol-forming substrate contained by the liquid storage fiber 220 leaking into the second cavity 1012, the mounting bracket 210 can also enclose a limiting space 2102. As shown, Figures 8 to 10 As shown, the mounting bracket 210 can include a main body part 211 and an extension part 212. The main body part 211 can be connected with the side wall 112 of the top shell 110, and can be arranged opposite and spaced apart from the top wall 111 and the bottom cover 120 respectively. Meanwhile, the main body part 211 can divide the cavity 101 into the first cavity 1011 and the second cavity 1012, and the main body part 211 can also be provided with a ventilation hole 2101 communicating the first cavity 1011 and the second cavity 1012. The extension part 212 is connected with the main body part 211 and located in the first cavity 1011, and the extension part 212 can jointly enclose the limiting space 2102 with the main body part 211. Part of the liquid storage fiber 220 can be located in the limiting space 2102 and abut against the main body part 211 and the extension part 212. In this way, the limiting space 2102 enclosed by the main body part 211 and the extension part 212 can be used to contain the liquid storage fiber 220, so as to reduce the probability of the aerosol-forming substrate contained by the liquid storage fiber 220 leaking into the second cavity 1012, thereby improving the sealing performance of the first cavity 1011.

[0058] Further, the side of the extension 212 away from the limiting space 2102 can also be in contact with the side wall 112, so as to avoid a large gap between the extension 212 and the side wall 112, which occupies the space of the first cavity 1011. Meanwhile, the extension 212 can also be arranged around the portion of the liquid storage fiber 220 close to the main body 211, and abut (abut against) the portion of the liquid storage fiber 220 close to the main body 211, so as to compress the portion of the liquid storage fiber 220 close to the main body 211. In this way, the extension 212 can slightly compress the portion of the liquid storage fiber 220 close to the mounting bracket 210, so as to reduce the residue of the substrate to be atomized in the liquid storage fiber 220.

[0059] Further, in order to ensure that the mounting bracket 210 can be assembled to the predetermined position, the mounting bracket 210 can also include a limiting portion 213. As shown in Figure 3 and Figures 8 to 9 The limiting portion 213 is connected with the main body 211 and located in the second cavity 1012, and the limiting portion 213 can also be arranged in a ring shape and can be clamped with the side wall 112 of the top shell 110 in the inhalation direction X. For example, the side wall 112 can have a convex edge 1121 located in the second cavity 1012, and the limiting portion 213 can abut against the convex edge 1121 and can be clamped with the convex edge 1121 in the direction in which the mounting bracket 210 (the main body 211) is away from the bottom cover 120, that is, the inhalation direction X. In this way, after the mounting bracket 210 is assembled into the top shell 110 from the side where the bottom cover 120 is located to the predetermined position, the limiting portion 213 can be clamped with the convex edge 1121 of the side wall 112, so as to limit the position of the mounting bracket 210 assembled into the top shell 110, thereby ensuring that the mounting bracket 210 can be assembled in place.

[0060] In some embodiments, the design of the limiting portion 213 can also be omitted, and the mounting bracket 210 can also be limited by other ways. As shown in Figure 8 and Figure 9As shown, the mounting bracket 210 can further include a positioning portion 214, and the side wall 112 of the top shell 110 can further be provided with a positioning groove 1105. The positioning portion 214 can be connected with the extension portion 212 and located on the side of the extension portion 212 facing the side wall 112, i.e., the side away from the limiting space 2102. Meanwhile, the positioning groove 1105 can be formed on the portion of the side wall 112 corresponding to the positioning portion 214, and the positioning portion 214 can be located in the positioning groove 1105 and can be clamped with the inner wall of the positioning groove 1105 in the direction in which the bottom cover 120 approaches or moves away from the mounting bracket 210 (the main body portion 211). In this way, when the mounting bracket 210 is loaded into the top shell 110 from the side where the bottom cover 120 is located to a predetermined position, the positioning portion 214 can be clamped with the inner wall of the positioning groove 1105, so as to limit the position of the mounting bracket 210 loaded into the top shell 110, thereby ensuring that the mounting bracket 210 can be assembled in place.

[0061] In some embodiments, the positions of the positioning groove 1105 and the positioning portion 214 can also be interchanged. That is, the positioning portion 214 can be provided on the side wall 112 and protrude towards the extension portion 212, and the side of the extension portion 212 away from the limiting space 2102 can be provided with the positioning groove 1105 corresponding to the positioning portion 214. Meanwhile, in some embodiments, the positioning portion 214 can not be limited to being connected with the extension portion 212, and the positioning portion 214 and the positioning groove 1105 can be located between the main body portion 211 and the side wall 112, or between the limiting portion 213 and the side wall 112. In addition, in some embodiments, when the mounting bracket 210 and the side wall 112 are limited by the positioning portion 214 and the positioning groove 1105, the design of the limiting portion 213 and the protruding edge 1121 can also be retained, which is not limited in the present embodiment.

[0062] In some embodiments, in addition to limiting by the positioning groove 1105 and the positioning portion 214 to omit the design of the limiting portion 213, the main body portion 211 can be directly clamped with the protruding edge 112. That is, the main body portion 211 can be provided on the protruding edge 112 and can be clamped with the protruding edge 112 in the inhalation direction X, so as to limit the mounting bracket 210 by cooperation of the main body portion 211 and the protruding edge 112. In addition, when limiting by cooperation of the main body portion 211 and the protruding edge 112, the design of the positioning portion 214 and the positioning groove 1105 can also be retained or omitted, which is not limited in the present embodiment.

[0063] The liquid storage fiber 220 is arranged in the first cavity 1011 and can absorb and contain the to-be-atomized substrate injected into the first cavity 1011. As shown in FIG. 1, the liquid storage fiber 220 can be arranged in the first cavity 1011 in a spiral manner. Figure 3 and Figure 10As shown, the liquid storage fiber 220 is located on opposite sides of the air intake direction X and abuts against the top wall 111 and the main body portion 211, and the circumferential side of the liquid storage fiber 220 can also abut against the side wall 112 and the extension portion 212. The orthographic projection of the liquid storage fiber 220 on the main body portion 211 is also arranged around the air passage hole 2101 and forms the air guide hole 2201. Meanwhile, the air guide hole 2201 can pass through the opposite sides of the liquid storage fiber 220 in the air intake direction X and is coaxially arranged with the air outlet hole 1101 and the air passage hole 2101, and the air guide hole 2201 is located between the air outlet hole 1101 and the air passage hole 2101 to connect the air outlet hole 1101 and the air passage hole 2101. In addition, the air guide hole 2201 can also be used to mount the heating assembly 300, and the aerosol can be formed by atomizing the aerosol-forming substrate stored in the liquid storage fiber 220 and conducted to the heating assembly 300 for heating and atomization.

[0064] Through the above arrangement, when the user sucks the mouth- containing air guide piece 520, air can enter the second cavity 1012 from the air inlet hole 1104 and enter the air guide hole 2201 (equivalent to the first cavity 1011) from the air passage hole 2101, and then is discharged to the outside of the first cavity 1011 from the air outlet hole 1101 and the air guide piece 520, while the aerosol in the air guide hole 2201 can be taken out with the airflow. In this embodiment, the liquid storage fiber 220 can be a liquid storage cotton, so that the extension portion 212 can extrude the part of the liquid storage fiber 220 close to the main body portion 211. Of course, the liquid storage fiber 220 can also be other structures with liquid storage capacity, which are not limited in this embodiment.

[0065] In some embodiments, the liquid storage fiber 220 can also abut against the top shell 110. For example, the side wall 112 of the top shell 110 can be provided with an annular barrier wall located in the first cavity 1011, the liquid storage fiber 220 can be arranged between the annular barrier wall and the top wall 111, and the opposite sides of the liquid storage fiber 220 in the air intake direction X can abut against the annular barrier wall and the top wall 111, respectively, and the circumferential side of the liquid storage fiber 220 can abut against the side wall 112. At this time, the design of the extension portion 212 can be omitted, and the main body portion 211 can be located on the side of the annular barrier wall away from the top wall 111 and block the through hole formed by the annular barrier wall to form the first cavity 1011 together with the annular barrier wall, the top wall 111 and the side wall 112.

[0066] The heating assembly 300 is arranged in the air guide hole 2201 and can heat the aerosol-forming substrate contained in the liquid storage fiber 220 to form an aerosol by atomization. As shown in FIG. 6, the heating assembly 300 can be a heating wire, and the heating wire can be arranged in the air guide hole 2201 and can be used to heat the aerosol-forming substrate contained in the liquid storage fiber 220 to form an aerosol by atomization. Figure 3 and Figure 8As shown, the heating assembly 300 can include an air guide tube 310, a liquid guide 320, and a heating element 330. The air guide tube 310 is arranged in the air guide hole 2201 and is provided with a hole communicating with the liquid storage fiber 220. The liquid guide 320 is arranged in the air guide tube 310 and blocks the hole of the air guide tube 310 communicating with the liquid storage fiber 220, and the liquid guide 320 can guide the to-be-atomized substrate contained in the liquid storage fiber 220 into the air guide tube 310. The heating element 330 is embedded in the liquid guide 320, and part of the heating element 330 also penetrates the air hole 2101 and is electrically connected to the control assembly 400, so that the heating element 330 can heat the to-be-atomized substrate contained in the liquid guide 320 under the control of the control assembly 400, so as to atomize the to-be-atomized substrate to form an aerosol.

[0067] In some embodiments, the structure of the heating assembly 300 can also not be limited to this. That is, the specific structure of the heating assembly 300 can also be adaptively adjusted according to design requirements, which is not limited to the scheme shown in the foregoing embodiments, and the present embodiment does not limit this.

[0068] The control assembly 400 is arranged in the second cavity 1012 and is electrically connected to the heating assembly 300 and the air adjusting assembly 600, respectively. Figure 3 and Figure 6 As shown, the control assembly 400 can include a circuit board 410, an electric core 420, and a pneumatic sensor 430. The circuit board 410 is arranged in the second cavity 1012 and is arranged opposite and spaced apart from the mounting bracket 210 (the main body part 211), and the circuit board 410 can be electrically connected to the heating assembly 300 and the air adjusting assembly 600, respectively. For example, part of the heating element 330 can enter the second cavity 1012 from the air hole 2101 and be electrically connected to the circuit board 410. At the same time, one side of the circuit board 410 facing the bottom cover 120 (the air adjusting assembly 600) can be provided with a trigger part 411 in sliding contact with the contact part 630, and the trigger part 411 can be electrically connected to the circuit board 410 and can trigger the corresponding electrical signal after the contact part 630 slides.

[0069] Further, the electric core 420 can be located between the circuit board 410 and the mounting bracket 210 (the main body part 211), and the electric core 420 can be electrically connected to the circuit board 410 and can supply power to the heating element 330 and the pneumatic sensor 430 and other structural parts through the circuit board 410. At the same time, since the electric core 420 is also arranged opposite to the air hole 2101, one side of the electric core 420 facing the main body part 211 is also covered with a liquid suction part 421 to absorb and contain the to-be-atomized substrate seeping into the electric core 420 from the air hole 2101. In addition, one side of the electric core 420 facing the circuit board 410 is also covered with a separation part 422 to separate the electric core 420 and the circuit board 410, so as to avoid the electric core 420 contacting the circuit board 410.

[0070] Furthermore, the pneumatic sensor 430 can be disposed on the side of the circuit board 410 away from the battery cell 420 and electrically connected to the circuit board 410. The pneumatic sensor 430 can detect the airflow in the second cavity 1012 to trigger a corresponding electrical signal to be transmitted to the circuit board 410, so that the control chip integrated on the circuit board 410 can control the heating element 330 to heat the atomized substrate. At the same time, in order to protect the pneumatic sensor 430, the side of the circuit board 410 away from the battery cell 420 is also provided with a protective member 431 surrounding the pneumatic sensor 430. The protective member 431 can be disposed around the pneumatic sensor 430 and abut against the circuit board 410 and the housing assembly 100 (bottom cover 120) respectively to form a receiving space for accommodating the pneumatic sensor 430. In addition, the protective member 431 can also have a communicating notch to connect the second cavity 1012 with the pneumatic sensor 430 in the receiving space, thereby realizing the detection of airflow in the second cavity 1012 by the pneumatic sensor 430.

[0071] In some embodiments, the atomizing device 10 may further include an electrical connection component 700. For example... Figure 6 As shown, the electrical connection component 700 can be installed through the bottom cover 120 and electrically connected to the circuit board 410. The electrical connection component 700 can also be used to connect to a charging cable, allowing an external power source to charge the battery cell 420 through the charging cable and the electrical connection component 700. Simultaneously, since the electrical connection component 700 is arranged adjacent to the pneumatic sensor 430, a portion of the protective component 431 can also be arranged around the electrical connection component 700, abutting against both the circuit board 410 and the bottom cover 120, thereby improving the sealing of the atomizing device 10.

[0072] The atomizing device 10 provided in this application includes a liquid storage component 200 comprising a mounting bracket 210 and a liquid storage fiber 220. The mounting bracket 210 can divide the cavity 101 of the housing component 100 into a first cavity 1011 and a second cavity 1012 that are connected to each other. The liquid storage fiber 220 is disposed in the first cavity 1011, and the control component 400 can also be disposed in the second cavity 1012. At least a portion of the liquid storage fiber 220 also abuts against the cavity wall of the first cavity 1011 corresponding to the housing component 100. This allows the housing component 100 to not only serve as the outer shell of the atomizing device 10, but also to be reused as a liquid storage shell to accommodate the liquid storage fiber 220, thereby simplifying the structure of the atomizing device 10 and reducing the material cost of the atomizing device 10.

[0073] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
