Description

Technical Field

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

[0002] Electronic atomizing devices utilize electronic heating elements that, when powered on or supplied with electricity, heat and atomize an atomizing substrate, producing a product containing volatile substances such as aerosols. An electronic atomizing device generally includes an atomizer, which comprises a mouthpiece, a coil assembly, and a chamber for storing the atomizing substrate. The coil assembly heats the substrate to generate an aerosol, which is then expelled from the atomizer through the mouthpiece. However, when the atomizer is inverted, the atomizing substrate within the chamber can easily leak through the mouthpiece. This not only wastes the atomizing substrate but also allows the leaked substrate to corrode the atomizer and other components of the electronic atomizing device, thus affecting its lifespan.

[0011] In some optional embodiments, the seal further includes a support portion disposed on the main body portion. The support portion abuts against the side of the liquid storage member facing the seal, thereby restricting the movement of the liquid storage member toward the nozzle member. A liquid storage space is formed between the liquid storage member and the seal, and the liquid storage space is in communication with the liquid storage tank.

[0012] In some alternative embodiments, in the first direction, the support portion protrudes relative to the main body portion toward the liquid reservoir, and the length of the support portion is greater than the length of the stop portion.

[0013] In some optional embodiments, the nozzle has an air outlet channel; the atomizing core assembly has an atomizing channel; the seal has an airflow channel for connecting the air outlet channel and the atomizing channel; the airflow channel passes through the main body and the stop portion along the first direction;

[0014] Wherein, on a plane perpendicular to the first direction, the orthographic projection of the atomizing channel is inside the outer contour of the orthographic projection of the airflow channel.

[0015] In some optional embodiments, the airflow channel includes a first air passage and a second air passage, the first air passage being located in the main body portion and the second air passage being located in the stop portion;

[0019] This application provides an electronic atomizing device, including a housing, a power supply component, and an atomizer as described above. The housing is used to mount the power supply component and the atomizer; the power supply component is used to supply power to the atomizer.

[0020] In some optional embodiments, the electronic atomizing device further includes at least one liquid reservoir component, at least one of said liquid reservoir components being detachably connected to the atomizer for replenishing the atomizing matrix to the atomizer; and / or,

[0021] The electronic atomizing device also includes a charging component, which is detachably connected to the power supply component and is used to replenish the power supply component with electrical energy.

[0022] The atomizer according to this embodiment includes a seal with a liquid reservoir and a stop portion. The seal is disposed between the mouthpiece and the housing assembly.

[0038] 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.

[0039] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0040] 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).

[0041] This application provides an atomizer 10, including a housing assembly 11, a mouthpiece 12, a liquid reservoir 13, an atomizing core assembly 14, and a sealing member 15. The housing assembly 11 and the mouthpiece 12 are assembled together in a first direction F1; the liquid reservoir 13 and the atomizing core assembly 14 are disposed within a storage cavity 111 inside the housing assembly 11; the sealing member 15 is disposed between the housing assembly 11 and the mouthpiece 12 to seal the storage cavity 111. The sealing member 15 includes a liquid reservoir 1511 and a stop portion 152. The two work together to prevent the atomizing matrix in the liquid reservoir 13 from leaking from the mouthpiece 12 when the atomizer 10 is inverted (in the first direction F1, the housing assembly 11 is placed above the mouthpiece 12), thereby helping to reduce the waste of atomizing matrix and improve the service life of the atomizer 10 and the electronic atomization device.

[0042] The atomizer 10 and electronic atomizing device of this application will be described below through specific embodiments.

[0043] Please see Figures 1 to 5The atomizer 10 includes a housing assembly 11, a mouthpiece 12, a liquid reservoir 13, an atomizing core assembly 14, and a sealing element 15. The housing assembly 11 has a storage chamber 111. One end of the housing assembly 11 along its axial direction has a mouthpiece mounting position 112, where the mouthpiece 12 is located. The mouthpiece 12 has an air outlet channel 121 that communicates with the outside of the atomizer 10. The liquid reservoir 13 is located within the storage chamber 111 and is used to store the atomizing matrix. The atomizing core assembly 14 is located within the storage chamber 111 and is used to heat the atomizing matrix to generate an aerosol. The atomizing core assembly 14 contains… The device has an atomizing channel 1411; a sealing element 15 is disposed between the housing assembly 11 and the nozzle assembly 12 to prevent leakage of the atomizing matrix in the liquid storage component 13; the sealing element 15 includes a main body 151 and a stop 152, the main body 151 is recessed at one end facing the liquid storage component 13 to form a liquid storage tank 1511, the stop 152 is disposed in the liquid storage tank 1511 and protrudes relative to the bottom wall of the liquid storage tank 1511; the sealing element 15 has an airflow channel 153, which is used to connect the air outlet channel 121 and the atomizing channel 1411; the airflow channel 153 passes through the main body 151 and the stop 152 along the first direction F1.

[0044] To describe the atomizer 10 and its components more clearly and in detail, three mutually perpendicular directions are defined in this document based on the structure of the atomizer 10: a first direction F1, a second direction F2, and a third direction F3; for example, the first direction F1 refers to... Figure 1 The vertical direction and the second direction F2 of the atomizer 10 shown refer to... Figure 1 The left and right directions and the first direction F1 of the atomizer 10 shown refer to... Figure 1 The atomizer 10 is shown in the front-to-back direction. When the atomizer 10 is assembled into an electronic atomizing device, Figure 1 The first direction F1 shown also refers to the up-down direction of the electronic atomizing device, and the second direction F2 refers to... Figure 1 The left and right directions and the first direction F1 of the atomizer 10 shown refer to... Figure 1 The front-to-back direction of the atomizer 10 shown.

[0045] In this application, the term "inverted" refers to the non-normal position of the atomizer 10 during use. Under normal use, the atomizer 10 is positioned with the mouthpiece 12 on top and the housing assembly 11 and its internal liquid reservoir 13 on the bottom. "Inverted" means the position where the mouthpiece 12 is on the bottom and the housing assembly 11 and its internal liquid reservoir 13 are on top.

[0046] Understandably, when the atomizer 10 is inverted, the liquid storage component 13 is located on top, and the atomizing matrix stored inside leaks into the mouthpiece 12 under the action of gravity, and is discharged from the atomizer 10 through the air outlet channel 121 of the mouthpiece 12. This results in the waste of the atomizing matrix and may also corrode the atomizer 10 and other components of the electronic atomizing device, such as the housing assembly 11 or the power supply component 30, thus affecting the service life of the atomizer 10 and the electronic atomizing device.

[0047] In this embodiment, the sealing element 15 has been improved. The sealing element 15 includes a liquid storage tank 1511 and a stop portion 152. After the atomized matrix leaks, it is stored in the liquid storage tank 1511. The stop portion 152 is disposed in the liquid storage tank 1511 and protrudes from the bottom wall of the liquid storage tank 1511. It cooperates with the side wall of the liquid storage tank 1511 to form a semi-closed structure with an opening facing the liquid storage component 13. That is, it forms a structure with an opening only facing the liquid storage component 13, which prevents the atomized matrix from flowing directly from the liquid storage component 13 to the nozzle component 12, reducing the leakage of the atomized matrix. At the same time, since the stop portion 152 and the main body 151 are provided with an airflow channel 153 along the first direction F1, which is connected to the atomization channel 1411 and the air outlet channel 121, a flow path is provided for the aerosol.

[0048] It should be noted that the term "aerosol" as used in this article can generally refer to substances that have been vaporized, atomized, sprayed or jetted, or otherwise transformed from solid or liquid form into an inhalable form containing suspended solid or liquid drug particles.

[0049] As used herein, the term "atomizing matrix" refers to any suitable compound or mixture of compounds that facilitates the formation of an aerosol (e.g., a stable aerosol that is substantially resistant to thermal degradation at the system's operating temperature) during use. Suitable atomizing matrices are well known in the art and include, but are not limited to: polyols such as triethylene glycol, 1,3-butanediol, and glycerol; esters of polyols such as mono-, di-, or triacetic acid esters of glycerol; and aliphatic esters of mono-, di-, or polycarboxylic acids such as dimethyl dodecanoate and dimethyl tetradecanoate. Atomizing matrices may include nicotine. Atomizing matrices may include water. Atomizing matrices may include glycerol (also known as glycerol) having a higher boiling point than nicotine. Atomizing matrices may include propylene glycol. Atomizing matrices may include plant-based materials. Atomizing matrices may include homogeneous plant substrates. Homogeneous plant substrates may contain volatile compounds. These compounds may be released from the atomizing matrix upon heating. Atomizing matrices include, but are not limited to, liquid matrices.

[0050] The liquid storage component 13 is constructed of a porous material, utilizing its own multiple microporous structures to adsorb and store the atomized matrix. Specifically, the liquid storage component 13 is constructed of porous fibers or porous ceramics. For example, the liquid storage component 13 is a liquid storage cotton made of cotton fibers.

[0051] In this embodiment, the main body 151 and the stop 152 can be integrally formed structures. In actual application, they can be designed and processed according to specific usage requirements. The integrated design can reduce the existence of assembly gaps, thereby reducing the risk of leakage of the atomized matrix at the seal 15. Of course, the main body 151 and the stop 152 can also be two separate structures, which can be assembled into one by corresponding connection methods (e.g., plug-in, threaded connection, adhesive or snap-fit, etc.), and the main body 151 and the stop 152 are sealed together.

[0052] Please see Figure 3 and Figure 4 In some embodiments, in the first direction F1, the length of the stop portion 152 is greater than the length of the side wall of the liquid storage tank 1511. It can also be understood that at least part of the structure of the stop portion 152 is located outside the liquid storage tank 1511. Thus, when the atomizer 10 is inverted, the atomizing matrix that leaks from the liquid storage component 13 to the seal 15 will be stored in the liquid storage tank 1511 until the liquid level is greater than the stop portion 152, at which point it can flow along the airflow channel 153 to the nozzle component 12. This effectively prevents the atomizing matrix from leaking from the nozzle component 12 when the liquid storage component 13 is oversaturated.

[0053] In this application, the length of the stop portion 152 refers to the dimension in the first direction F1, and the side wall length of the liquid storage tank 1511 refers to the dimension in the first direction F1. The side wall length of the liquid storage tank 1511 can also be understood as the depth of the liquid storage tank 1511.

[0054] In some embodiments, the depth of the liquid storage tank 1511 is 0.1mm-5mm; the length of the stop portion 152 is 0.3mm-5mm. For example, the depth of the liquid storage tank 1511 can be 0.2mm, and the length of the stop portion 152 can be 0.4mm, or the depth of the liquid storage tank 1511 can be 0.3mm, and the length of the stop portion 152 can be 0.6mm.

[0055] Understandably, due to the fluidity of the atomizing matrix, it will flow along the wall under the influence of gravity. When the atomizing matrix leaks downwards from the reservoir 13, it will flow along the side wall of the reservoir 1511 and the stop 152 towards the side wall of the reservoir 1511, eventually flowing to the bottom wall of the reservoir 1511 under gravity and being blocked by the stop 152, which is longer than the length (depth) of the side wall of the reservoir 1511. When the atomizer 10 returns to its normal position, the atomizing matrix will flow along the side wall of the reservoir 1511 and the side wall of the stop 152 towards the reservoir 13, which can reduce the waste of the atomizing matrix.

[0056] In some specific embodiments, the sidewall of the liquid storage tank 1511 extends along the first direction F1, that is, the cross-section of the liquid storage tank 1511 in the first direction F1 remains consistent, which facilitates processing. The cross-section of the liquid storage tank 1511 can be rectangular or circular, and there is no limitation here.

[0057] In other specific embodiments, the sidewall of the liquid storage tank 1511 can be inclined relative to the first direction F1, and the sidewall of the liquid storage tank 1511 gradually inclines inward in the direction away from the liquid storage component 13 along the first direction F1, so that the liquid storage tank 1511 forms a frustum-shaped groove structure. When the atomizer 10 is inverted, the liquid storage tank 1511 forms a funnel-like structure that is larger at the top and smaller at the bottom, so as to guide the atomizing matrix using the inclined sidewall of the liquid storage tank 1511. The inclination angle of the sidewall of the liquid storage tank 1511 can be set according to the specific size of the liquid storage tank 1511 and the usage requirements. For example, the angle between the sidewall of the liquid storage tank 1511 and the first direction F1 can be set in the range of 5° to 15°.

[0058] Please see Figure 3 In some embodiments, the sealing member 15 further includes a support portion 154, which is disposed on the main body portion 151. The support portion 154 abuts against the side of the liquid storage member 13 facing the sealing member 15, thereby restricting the movement of the liquid storage member 13 toward the nozzle member 12. A liquid storage space is formed between the liquid storage member 13 and the sealing member 15, and the liquid storage space is connected to the liquid storage tank 1511. The support portion 154 can limit and fix the liquid storage member 13. This liquid storage space can store the supersaturated part of the atomizing matrix in the liquid storage member 13, and can also serve as a pressure balancing space to ensure a smooth supply of the atomizing matrix.

[0059] Understandably, a negative pressure will form inside the liquid reservoir 13 due to the reduction of liquid, hindering the subsequent supply of liquid and its internal air pressure. To solve this problem, a gap is left between the liquid reservoir 13 and the storage cavity 111 (especially in the normal position, the top of the liquid reservoir 13 and the storage cavity 111) as a pressure balance space to ensure that the atomizing matrix can flow smoothly to the atomizing core assembly 14. Based on this, when the atomizer 10 is inverted, the liquid reservoir 13 can move towards the mouthpiece 12 under the action of gravity, and a direct liquid channel is established between it and the mouthpiece 12, so that the leaked atomizing matrix can flow directly to the mouthpiece 12.

[0060] In this embodiment, the sealing member 15 includes a support portion 154, which can abut against the liquid storage member 13. When the atomizer 10 is inverted, it can prevent the liquid storage member 13 from moving toward the mouthpiece 12, thus blocking the liquid channel between the liquid storage member 13 and the mouthpiece 12. The leaked atomizing matrix flows to the liquid storage tank 1511 after passing through the liquid storage space. At the same time, when the atomizer 10 is in the normal position, the supersaturated atomizing matrix in the liquid storage member 13 can also be stored in the liquid storage space.

[0061] Please see Figure 3 and Figure 4 In some embodiments, in the first direction F1, the support portion 154 protrudes from the side of the main body portion 151 toward the liquid reservoir 13, and the length of the support portion 154 is greater than the length of the stop portion 152. The greater length of the support portion 154 than the stop portion 152 allows for a gap between the stop portion 152 and the liquid reservoir 13 when the atomizer 10 is inverted. Since the airflow channel 153 within the stop portion 152 is directly connected to the air outlet channel 121 of the nozzle portion 12, the gap between them also reduces the risk of atomization matrix leakage.

[0062] In some specific embodiments, the support portion 154 can be disposed inside the liquid storage tank 1511, that is, one end of the support portion 154 is disposed on the bottom wall of the liquid storage tank 1511, and the other end protrudes relative to the bottom wall of the liquid storage tank 1511.

[0063] In some other specific embodiments, the support portion 154 may be disposed on the end face of the side wall of the liquid storage tank 1511 facing the liquid storage component 13, that is, disposed on the main body portion 151, and the support portion 154 protrudes relative to the side wall of the liquid storage tank 1511.

[0064] In some embodiments, the number of support portions 154 can be at least one, for example, two, three or more. The at least one support portion 154 should be evenly distributed so that the liquid storage component 13 is subjected to uniform force.

[0065] In some embodiments, the cross-section of the support portion 154 can be circular, elliptical, rectangular, polygonal, or other irregularly shaped.

[0066] In some embodiments, on a plane perpendicular to the first direction F1, the orthographic projection of the atomizing channel 1411 lies inside the orthographic projection outline of the airflow channel 153. This can also be understood as the projection of the atomizing channel 1411 being completely surrounded by the projection outline of the airflow channel 153 within this projection plane, with no part exceeding the projection range of the airflow channel 153. That is, the maximum size of the atomizing channel 1411 within this plane is necessarily smaller than the maximum size of the airflow channel 153. Based on this design, when the atomizer 10 is inverted, the atomizing matrix and condensate can flow along the airflow channel 153 to the storage chamber 111 and the liquid reservoir 13, preventing the atomizing matrix and condensate from flowing to the atomizing core assembly 14. This avoids the atomizing matrix and condensate from flowing to the atomizing core assembly 14, which would cause violent "splashing" due to instantaneous heating and vaporization, resulting in a poor aerosol taste and the risk of dry burning. Furthermore, this horn-like structural design facilitates the installation of the atomizing core assembly 14.

[0067] Please continue reading. Figure 4 In some embodiments, the airflow channel 153 includes a first air passage 1531 and a second air passage 1532. The first air passage 1531 is formed in the main body portion 151, and the second air passage 1532 is formed in the stop portion 152. In the first direction F1, the inner diameter of the second air passage 1532 gradually increases in the direction away from the first air passage 1531 to form a trumpet-shaped structure that is smaller at the top and larger at the bottom.

[0068] Understandably, when the atomizer 10 is not in use, the residual aerosol condenses into condensate after cooling and adheres to the mouthpiece 12. When the atomizer 10 is inverted, the condensate may flow back into the housing assembly 11 along the air outlet channel 121 and the airflow channel 153. The atomizing matrix that leaks into the mouthpiece 12 can also flow back along the airflow channel 153 when in the normal position.

[0069] In this embodiment, the funnel-shaped structure of the second air passage 1532 can guide the atomizing matrix and condensate to flow towards the liquid storage device 13, preventing them from falling into the atomizing channel 1411 and onto the atomizing core 142.

[0070] Please see Figure 5 In some embodiments, the atomizing core assembly 14 includes an atomizing tube 141 and an atomizing core 142. The atomizing tube 141 is a hollow structure open at both ends. The atomizing tube 141 is disposed within the storage cavity 111 and defines an atomizing channel 1411. The atomizing core 142 is disposed within the atomizing channel 1411. One end of the atomizing tube 141 is inserted into the airflow channel 153, which ensures the installation stability and reliability of the atomizing core assembly 14. Simultaneously, the atomizing matrix or condensate flows along the inner wall of the airflow channel 153. Inserting the atomizing tube 141 into the airflow channel 153 also prevents the atomizing matrix or condensate from falling into the atomizing tube 141. A gap exists between the atomizing tube 141 and the airflow channel 153 to allow the atomizing matrix and condensate to pass through. Figure 5 The arrows in the diagram illustrate the flow direction of the atomizing matrix when the atomizer 10 is inverted.

[0071] In some embodiments, a limiting portion 1533 is provided on the inner wall of the airflow channel 153 near the air outlet channel 121 to limit the depth of the atomizing tube 141 inserted into the airflow channel 153.

[0072] In some embodiments, the atomizer 10 further includes a base 16, which is disposed at the end of the housing assembly 11 opposite to the mouthpiece 12. A base seal 17 is also provided between the base 16 and the housing assembly 11. The base seal 17 cooperates with the housing assembly 11 and the seal 15 to form a storage cavity 111. One end of the atomizing core assembly 14 is mounted on the base seal 17 and can be electrically connected to the power supply assembly 30 through a lead or pin.

[0073] In some embodiments, a liquid guide port 1412 is provided at the position corresponding to the atomizing tube 141 and the atomizing core 142. The liquid guide port 1412 allows the atomizing core 142 to contact the liquid storage component 13, thereby providing the atomizing matrix to the atomizing core 142. The atomizing core 142 includes a heating element 1421, a liquid guiding element 1422, and a conductive part 1423. The liquid guiding element 1422 is attached to the atomizing tube 141 at the liquid guiding port 1412 and can contact the liquid storage unit 13. The heating element 1421 is attached to the liquid guiding element 1422. The conductive part 1423 is used to realize the conductive connection between the heating element 1421 and the power supply component 30, so that the heating element 1421 can generate heat after being energized or powered. The atomizing matrix can be transported from the liquid storage unit 13 to the liquid guiding element 1422 by capillary effect. After the heating element 1421 attached to the liquid guiding element 1422 is heated, it heats and atomizes the atomizing matrix on the liquid guiding element 1422 to generate an aerosol.

[0074] In some embodiments, the heating element 1421 can be a mesh structure formed by multiple heating wires connected in a cross manner, or the heating element 1421 can be a heating tube with a hollow structure. The mesh structure and the hollow structure can increase the contact area between the atomizing matrix and the heating element 1421 to improve the heating efficiency.

[0075] In some embodiments, the atomizer 10 is further provided with a liquid inlet 1111 and a liquid guiding structure 18 communicating with the liquid inlet 1111, through which the atomizer 10 and the liquid storage assembly 40 can be connected. The atomizer 10 is also provided with a first docking structure 19 for connecting with a second docking structure 42 of the liquid storage assembly 40 to realize the connection between the atomizer 10 and the liquid storage assembly 40. The liquid inlet 1111, the liquid guiding structure 18 and the first docking structure 19 are all structures that need to cooperate with the liquid storage assembly 40, and will be described in detail in the embodiments of the electronic atomizing device below, and will not be elaborated on further here.

[0076] Please see Figures 1 to 9 This application also provides an electronic atomizing device, including a housing 20, an atomizer 10, and a power supply assembly 30. The housing 20 can be understood as an assembly of multiple components. The power supply assembly 30 and the atomizer 10 can both be housed within the assembly to form an integrated electronic atomizing device, facilitating the carrying and transportation of the electronic atomizing device. The atomizer 10 is the same as the atomizer 10 described in the above embodiment, and will not be elaborated further here. The following only describes its cooperation structure with other components.

[0077] Please see Figure 7 The power supply component 30 includes a battery 31 and a circuit board 32 that are electrically connected to each other. The circuit board 32 is provided with a power supply section 33, which can be electrically connected to the conductive section 1423 of the atomizing core component 14.

[0078] In some embodiments, the power supply unit 33 and the conductive part 1423 are plugged together. This can also be understood as one of the power supply unit 33 and the conductive part 1423 including a protruding structure and the other including a recessed structure, with the protruding structure plugged into the recessed structure to achieve a conductive connection between them. For example, the power supply unit 33 includes a conductive spring pin configured as a protruding structure, and the conductive part 1423 is a recessed structure. When the power supply assembly 30 and the atomizer 10 are assembled, the conductive spring pin is elastically disposed within the recessed structure, which can improve the stability of the conductive connection between them. In other examples, the power supply unit 33 and the conductive part 1423 are fitted together.

[0079] In some embodiments, the battery 31 of the power supply component 30 is a rechargeable battery 31 that can be repeatedly charged and discharged and can be charged by an external power source.

[0080] In some embodiments, the electronic atomizing device further includes at least one liquid storage component 40, which is detachably connected to the atomizer 10 for replenishing the atomizing matrix to the atomizer 10; and / or, the electronic atomizing device further includes a charging component 50, which is detachably connected to the power supply component 30 for replenishing the power supply component 30 with electrical energy.

[0081] Although the liquid reservoir 13 within the storage chamber 111 stores atomizing matrix, its capacity is limited, making it unsuitable for large-capacity applications. In this embodiment, by providing at least one liquid reservoir 40, the atomizing matrix stored within it can compensate for the limited capacity of the atomizer 10 itself. Since the liquid reservoir 40 and the atomizer 10 are detachably connected, the atomizer 10 can be used alone or in combination with the liquid reservoir 40, thus adapting to different needs in both small and large capacity scenarios. The liquid reservoir 40 can also store different flavored atomizing matrices, allowing for the replacement of different liquid reservoirs 40 to enrich the flavor profile of the electronic atomizing device and enhance the user experience.

[0082] In some embodiments, the power supply component 30 includes a power receiving part 34, which is electrically connected to the battery 31. The charging component 50 includes a charging plate 51, a rechargeable battery 52, and a charging part 53. The charging part 53 is electrically connected to the power receiving part 34 of the power supply component 33, so that the charging component 50 and the power supply component 30 are electrically connected, thereby enabling the power supply component 30 to replenish the battery 31 of the power supply component 30 and improve the battery 31's battery life.

[0083] In some embodiments, the charging assembly 50 further includes a charging chamber 54, a charging plate 51 and a rechargeable battery 52 disposed within the charging chamber 54, one end of the charging part 53 being electrically connected to the charging plate 51, and the other end being at least partially exposed outside the charging chamber 54 so that it can be electrically connected to the power receiving part 34.

[0084] Please see Figure 7 In some embodiments, the storage chamber 111 of the atomizer 10 has a liquid inlet 1111, and the liquid storage assembly 40 includes a liquid storage chamber 41 with a liquid outlet 411. When the liquid storage assembly 40 and the atomizer 10 are used together, the liquid inlet 1111 and the liquid outlet 411 are connected in a liquid path, which can transfer the atomizing matrix in the liquid storage assembly 40 to the liquid storage component 13 in the storage chamber 111.

[0085] In some embodiments, a liquid guiding structure 18 is provided at the liquid inlet 1111. The liquid guiding structure 18 is used to open the liquid outlet 411 to allow liquid to flow between the storage chamber 111 and the liquid storage chamber 41. The liquid guiding structure 18 includes a liquid guiding channel 181 and a porous liquid guiding element 182 disposed in the liquid guiding channel 181. The porous liquid guiding element 182 is used to adsorb and guide the atomized matrix.

[0086] The term "porous liquid-conducting element" refers to an element with multiple micropores that utilizes its own capillary effect to adsorb and guide liquids, offering the advantages of continuous and uniform infusion.

[0087] The porous liquid guiding element 182 in this application is made of porous fiber material or porous ceramic material. The porous liquid guiding element 182 is disposed in the liquid guiding channel 181. One end of the porous liquid guiding element 182 is connected to the storage cavity 111 and in contact with the liquid storage component 13. The other end is connected to the storage cavity 41 when the liquid storage assembly 40 and the atomizing body atomizer 10 are connected. In this way, the atomizing matrix in the storage cavity 41 is stably transferred to the liquid storage component 13 in the storage cavity 111 by utilizing the capillary effect.

[0088] In some embodiments, a piercing bevel (not shown) is provided at the end of the fluid guiding structure 18 away from the housing assembly 11 to facilitate piercing the elastic membrane, thereby enabling communication between the fluid guiding structure 18 and the reservoir 41. There may be one or two piercing bevels, with the two bevels symmetrically arranged along the central axis of the fluid guiding structure 18. Alternatively, multiple piercing bevels may be provided, evenly distributed around the central axis of the fluid guiding structure 18.

[0089] In some embodiments, the liquid outlet 411 includes a liquid outlet 4111 and a sealing member 4112 disposed at the liquid outlet 4111. The sealing member 4112 is movable relative to the liquid storage chamber 41 to open the liquid outlet 4111, and the sealing member 4112 is repositioned to close the liquid outlet 4111. The liquid guiding structure 18 is used to drive the sealing member 4112 to move. The sealing member 4112 is constructed as an elastic sealing plug or sealing membrane to seal the liquid outlet 4111 and prevent leakage of the atomizing matrix in the liquid storage chamber 41. For example, a sealing plug is disposed at the liquid outlet 4111. When the liquid storage assembly 40 and the atomizer 10 are connected, the liquid guiding structure 18 can push the sealing plug into the liquid storage chamber 41 to make the liquid guiding structure 18 communicate with the liquid storage chamber 41. Alternatively, the sealing plug can be removed before connection to expose the liquid outlet 4111 for communication with the liquid guiding structure 18. In another example, an elastic membrane is provided at the liquid outlet 4111. When the liquid storage assembly 40 and the atomizer 10 are connected, the liquid guiding structure 18 can push the elastic membrane to deform so that the liquid guiding structure 18 can enter the liquid storage chamber 41 and communicate with the liquid storage chamber 41. After the liquid guiding structure 18 is removed from the liquid storage chamber 41, the elastic membrane restores its deformation and blocks the liquid outlet 4111 to reseal the liquid storage chamber 41 and prevent leakage of the atomizing matrix.

[0090] In some embodiments, the atomizer 10 is provided with a first docking structure 19 on one side along the second direction F2; the liquid storage assembly 40 is provided with a second docking structure 42, which is detachably connected to the first docking structure 19 so that the liquid storage assembly 40 and the atomizer 10 are detachably connected along the second direction F2 so as to transfer the atomizing matrix in the liquid storage chamber 41 to the storage chamber 111.

[0091] In some embodiments, one of the first docking structure 19 and the second docking structure 42 includes an elastic buckle 191 and the other includes a slot 421, wherein the elastic buckle 191 is used to engage with the slot 421.

[0092] Please see Figure 8 and Figure 9 In some embodiments, the first docking structure 19 includes two elastic buckles 191 disposed opposite to each other on both sides of the atomizer 10 along the third direction F3, and the second docking structure 42 includes two slots 421 disposed opposite to each other on both sides of the liquid storage assembly 40 along the third direction F3. It can also be understood that an elastic buckle 191 is provided on each side of the housing assembly 11 along the third direction F3, and a slot 421 is provided on each side of the liquid storage assembly 40 along the third direction F3. When the liquid storage assembly 40 docks with the atomizer 10 along the second direction F2, the elastic buckle 191 is engaged in the slot 421.

[0093] Please continue reading. Figure 8 and Figure 9 In some embodiments, the first docking structure 19 further includes at least one first magnetic element 192, and the second docking structure 42 further includes at least one second magnetic element 422, which is used to magnetically connect with the first magnetic element 192 in a one-to-one correspondence. For example, the first docking structure 19 further includes two first magnetic elements 192, which are spaced apart along a first direction F1, and the second docking structure 42 further includes two second magnetic elements 422, which are spaced apart along the first direction F1 and magnetically connected with the first magnetic elements 192 in a one-to-one correspondence. The arrangement of the first magnetic elements 192 and the second magnetic elements 422 not only makes the connection between the liquid storage component 40 and the atomizer 10 more convenient, but also guides and positions the connection between the liquid storage component 40 and the atomizer 10, enabling rapid installation. Of course, in other examples, the number of first magnetic elements 192 and second magnetic elements 422 can also be three, four, or more.

[0094] Please see Figure 6 The outer casing 20 has a first mounting portion 21 for detachable installation of the atomizer 10 and the liquid storage assembly 40. When the atomizer 10 is installed in the first mounting portion 21, the power supply assembly 30 and the atomizer 10 are electrically connected, so that the atomizer 10 can heat the atomization substrate after being energized or powered. The atomizer 10 and the liquid storage assembly 40 are detachably connected to the outer casing 20, which facilitates the removal and installation of the atomizer 10 and the liquid storage assembly 40, and helps to replace the atomizer 10 or the liquid storage assembly 40. During assembly, the atomizer 10 can be installed independently in the outer casing 20 and electrically connected to the power supply assembly 30 for direct use, or it can be assembled with the liquid storage assembly 40 and then installed in the outer casing 20.

[0095] In some embodiments, the first mounting portion 21 is provided with a first mounting opening 211 on one side along the first direction F1, and the atomizer 10 and the liquid storage assembly 40 can be inserted into or removed from the first mounting portion 21 through the first mounting opening 211. Alternatively, it can be understood that the atomizer 10 and the liquid storage assembly 40 can be inserted into or removed from the first mounting portion 21 along the first direction F1. Figure 6 The electronic atomizing device shown is mounted vertically on or removed from the first mounting part 21, thereby making the atomizer 10 and the liquid storage assembly 40 detachably connected to the housing 20.

[0096] Please continue reading Figure 6 In some embodiments, the housing 20 also has a second mounting portion 22, which is arranged sequentially with the first mounting portion 21 along the first direction F1. The second mounting portion 22 is provided with a second mounting opening 221 on one side along the first direction F1. The second mounting opening 221 is used for the charging component 50 to be inserted into or removed from the second mounting portion 22. It can also be understood that the housing 20 is provided with a first mounting opening 211 and a second mounting opening 221 opposite to each other in the first direction F1. The first mounting opening 211 is used for assembling and disassembling the atomizer 10, and the second mounting opening 221 is used for assembling and disassembling the charging component 50.

[0097] In some embodiments, the second mounting portion 22 can also be used to invert the liquid storage assembly 40, so that the liquid outlet 411 of the liquid storage assembly 40 is positioned closer to the top, preventing the atomizing matrix from leaking from the liquid outlet 411 under gravity. A first limiting member 223 is provided at the second mounting portion 22, and a second limiting member 44 is provided on the liquid storage assembly 40, so that the liquid storage assembly 40 can be fixed at the second mounting portion 22. In some examples, the charging chamber 54 may also be provided with a second limiting member 44. One of the first limiting member 223 and the second limiting member 44 is a limiting protrusion, and the other is a limiting groove. With this design, two liquid storage assemblies 40 can be selectively provided on the electronic atomizing device to meet the user's large-capacity needs when traveling, or one liquid storage assembly 40 and one charging assembly 50 can be selectively provided, thereby improving the battery life of the electronic atomizing device in terms of both capacity and power.

[0098] In some embodiments, to facilitate the installation of the charging assembly 50, the atomizer 10, and the liquid storage assembly 40, the first mounting portion 21 is provided with a first guide member 212 extending along a first direction F1, and the liquid storage assembly 40 is provided with a second guide member 43 extending along the first direction F1. The first guide member 212 is slidably connected to the second guide member 43, so that after the atomizer 10 and the liquid storage assembly 40 are assembled, they are synchronously and stably installed on the first mounting portion 21 or removed from the first mounting portion 21 under the cooperation of the first guide member 212 and the second guide member 43; and / or, the second mounting portion 22 The charging assembly 50 has a third guide 222 extending along the first direction F1, and a fourth guide 541 extending along the first direction F1. The third guide 222 is slidably connected to the fourth guide 541, so that the atomizer 10 is stably installed on or removed from the second mounting part 22 under the cooperation of the third guide 222 and the fourth guide 541. This facilitates charging the power supply assembly 30, or allows the charging assembly 50 to be detached separately and connected to an external power source for power replenishment, or allows for direct replacement of the charging assembly 50. In some examples, the second guide 43 on the liquid storage assembly 40 can also cooperate with the third guide 222 on the second mounting part 22 to guide the liquid storage assembly 40 to be installed on or removed from the second mounting part 22.

[0099] In some embodiments, one of the first guide member 212 and the second guide member 43 is a slide rail, and the other is a slider. Similarly, one of the third guide member 222 and the fourth guide member 541 is a slide rail, and the other is a slider.

[0100] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
