Description

Technical Field

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

[0002] Electronic atomizing devices use electric heating to heat the atomizing matrix, atomizing it into fine aerosol particles for users to inhale.

[0003] In related technologies, electronic atomizing devices use multiple chambers to meet users' needs for various flavors or functions. However, these devices generally employ a design where each chamber has its own dedicated atomizer core assembly. While this structure ensures the independence of the atomization process within each chamber, the need for multiple atomizer core assemblies leads to a more complex overall structure, increasing the number of parts, assembly difficulty, and process requirements during manufacturing, thus significantly raising production costs. Utility Model Content

[0004] This application provides an electronic atomizing device that can at least partially or completely solve the above-mentioned technical problems and can avoid the occurrence of flavor cross-contamination.

[0008] The liquid storage chamber and the atomizing core assembly are movable relative to each other, so that the heating element can selectively contact the liquid guiding element provided in one of the at least two storage chambers. When the heating element is in contact with the liquid guiding element, the heating element can heat the atomizing matrix guided by the liquid guiding element to generate an aerosol.

[0009] In some optional embodiments, the electronic atomizing device further includes a support, on which the atomizing core assembly is disposed; the liquid storage chamber has a through air outlet channel, the support is provided with a first air inlet channel, and the atomizing base is provided with a second air inlet channel, the second air inlet channel being used to connect the first air inlet channel and the air outlet channel.

[0010] In some alternative embodiments, at least two of the storage chambers are arranged around the central axis of the air outlet channel, at least a portion of the atomizing core assembly is disposed within one end of the air outlet channel, and the liquid reservoir is rotatable relative to the atomizing core assembly about the central axis.

[0011] In some optional embodiments, the bracket is provided with a first sliding part, and the atomizing seat is provided with a second sliding part. The bracket and the atomizing seat are movably connected through the first sliding part and the second sliding part. The first sliding part and the second sliding part can slide relative to each other in a direction close to or away from the central axis, and drive the heating element to fit or separate from the corresponding liquid guiding element. When the liquid guiding element fits with the heating element, the second air inlet channel connects the first air inlet channel and the air outlet channel. When the liquid guiding element separates from the heating element, the second air inlet channel blocks the connection between the first air inlet channel and the air outlet channel.

[0012] In some alternative embodiments, the electronic atomizing device further includes a switching component for driving the atomizing base to move in a direction close to or away from the central axis.

[0013] In some alternative embodiments, the switching component includes a drive member and an elastic member, one end of the drive member and one end of the elastic member being connected to the atomizing seat, one end of the drive member extending out of the electronic atomizing device for operation, and the elastic member being used to apply an elastic restoring force to the atomizing seat to move closer to the liquid guide member.

[0014] In some optional embodiments, the inner side of the liquid storage chamber is provided with a liquid guiding opening, the liquid guiding opening corresponds to the atomizing core assembly, the liquid guiding element is disposed near the inner side of the liquid storage chamber, and the end of each liquid guiding element near the atomizing core assembly is blocked at the liquid guiding opening, the aerosol generated by the atomizing matrix on the liquid guiding element by the atomizing core assembly can flow through the atomizing core assembly into the air outlet channel.

[0015] In some optional embodiments, the storage cavity is provided with a liquid storage element for storing the atomizing matrix; one side of the liquid guiding element is attached to the liquid storage element, and at least a portion of the other side is disposed at the liquid guiding opening for guiding the atomizing matrix in the liquid storage element to the heating element.

[0016] In some optional embodiments, the liquid storage chamber is provided with a first locking part, and the atomizing seat is provided with a second locking part. When the heating element is in contact with the liquid guiding member, the first locking part and the second locking part are locked, restricting the relative movement of the atomizing core assembly between two adjacent storage cavities in the liquid storage chamber.

[0017] In some optional embodiments, the electronic atomizing device further includes a housing assembly, within which a power supply assembly is disposed, the power supply assembly and the atomizing core assembly being electrically connected; at least a portion of the atomizing core assembly is disposed within the housing assembly, a first mating portion is provided on the liquid storage chamber, and a second mating portion is provided on the housing assembly, the first mating portion and the second mating portion being movably engaged to allow the liquid storage chamber and the atomizing core assembly to move relative to each other.

[0018] The electronic atomizing device according to this embodiment includes a liquid storage chamber and an atomizing core assembly. The liquid storage chamber and the atomizing core assembly are relatively movable, allowing the heating element in the atomizing core assembly to selectively contact a liquid guiding element provided in one of at least two storage chambers within the liquid storage chamber. When the heating element is in contact with the liquid guiding element, the heating element heats the atomizing matrix guided by the liquid guiding element to generate an aerosol. Thus, the structural design of at least two storage chambers and one atomizing core assembly reduces the design of internal components and structures of the electronic atomizing device, lowers assembly difficulty and process requirements, and effectively reduces its production cost. Furthermore, switching between storage chambers directly corresponds to switching the liquid guiding element in contact with the heating element, avoiding flavor transfer due to residual atomizing matrix, which helps improve the taste of the aerosol and enhances the user experience.

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.

[0036] 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).

[0037] Please see Figures 1 to 7 Some embodiments disclose an electronic atomizing device that uses electric heating to heat an atomizing matrix, causing it to atomize and generate an aerosol. The electronic atomizing device may include a liquid reservoir 100, an atomizing core assembly 200, a power supply assembly 300, a mouthpiece 600, and a housing assembly 400. In some examples, the electronic atomizing device may also include a switching assembly 500 capable of switching between the liquid reservoir 100 and the atomizing core assembly 200 to meet different flavor or functional needs, which will be described in detail below. The electronic atomizing device may also include an interactive assembly (not shown) electrically connected to the power supply assembly 300, through which the operating status of the electronic atomizing device can be switched and viewed. Those skilled in the art will understand that the [specific features / functions] described herein... Figures 1 to 7 This illustration is intended only to show the structure of an electronic atomizing device and does not imply that the structure of an electronic atomizing device can only be shown in this way. The components and structure of the electronic atomizing device will be described in detail below. Before proceeding with the detailed description, some terms used in this application will be explained.

[0038] In this application, "aerosol" can generally be used to refer to a substance that has been vaporized, atomized, sprayed or jetted, or otherwise transformed from a solid or liquid form into an inhalable form containing suspended solid or liquid drug particles.

[0039] The term "atomizing matrix" in this application refers to any suitable compound or mixture of compounds that facilitates aerosol formation during use, including but 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. Nicotine may also be included. Alternatively, glycerol (also known as glycerol) with a higher boiling point than nicotine may be included. Propylene glycol or plant-based materials may also be included. The atomizing matrix is ​​typically liquid with a certain degree of fluidity, allowing it to be transported under capillary action, gravity, negative pressure, etc.

[0040] The liquid reservoir 100 stores the atomizing matrix and transfers it to the atomizing core assembly 200. The liquid reservoir 100 has a storage chamber 110 inside, where the atomizing matrix can be stored directly or via an intermediate medium. To meet users' needs for multiple flavors or functions, such as satisfying requirements for refreshing, sweet, or different aerosol volumes, the liquid reservoir 100 has at least two independent storage chambers 110. Different storage chambers 110 store different atomizing matrices, producing aerosols with different flavors. The independent storage chambers 110 can also be understood as being sealed to each other, preventing cross-contamination of flavors between the atomizing matrices in different chambers and helping to optimize the aerosol's taste.

[0041] In some embodiments, the intermediate medium is a liquid storage device 120 with multiple micropores. It can also be understood that the liquid storage device 120 is provided in the storage cavity 110. The liquid storage device 120 can be made of porous ceramic material or porous fiber material (e.g., liquid storage cotton). After the liquid storage device 120 adsorbs and stores the atomizing matrix inside, it is filled into the storage cavity 110. Alternatively, after being filled into the storage cavity 110, the atomizing matrix can be naturally adsorbed and stored by adding an external atomizing matrix. By setting the liquid storage device 120, the speed at which the atomizing matrix is ​​uniformly transported from the storage cavity 110 to the atomizing core assembly 200 can be increased to ensure uniform aerosol generation. It can also prevent the atomizing matrix from being too small and producing a burnt taste that affects its taste, and it also helps to extend the service life of the atomizing core assembly 200.

[0042] In some embodiments, the number of storage chambers 110 can be two, three, four, or more, without much limitation. Simultaneously, different flavored atomizing substrates can be stored in the storage chambers 110 according to user needs. For example, one chamber may store a cooling atomizing substrate, another a substrate providing a basic experience, and a third a sweet atomizing substrate, to meet users' needs for different flavors. Alternatively, atomizing substrates releasing different concentrations of nicotine can be stored in different storage chambers 110 to meet users' needs for different aerosol volumes. Alternatively, the total storage capacity of the atomizing substrate can be increased simply by using at least two storage chambers 110.

[0043] Please see Figure 1In some embodiments, each storage cavity 110 is further provided with a liquid guiding element 130. This can also be understood as each storage cavity 120 having a corresponding liquid guiding element 130. The liquid guiding element 130 contacts the storage cavity 110 containing the storage cavity 120, and under specific conditions, it can also contact the atomizing core assembly 200, thereby utilizing capillary effect to adsorb and guide the atomizing matrix on the storage cavity 120 to the atomizing core assembly 200. In some examples, the liquid guiding element 130 is coaxial with the storage cavity 120 and of equal length (length refers to the dimension in the extending direction, which can also be understood as the axial dimension). The liquid guiding element 130 has two opposing sides, one side of which is completely in contact with the storage cavity 120, and at least a portion of the other side contacts the atomizing core assembly 200 under the aforementioned specific conditions to facilitate the transfer of the atomizing matrix. In other examples, when the atomizing core assembly 200 is arranged laterally (perpendicular to the axial direction of the liquid reservoir 120), the liquid guide 130 can be disposed at one end of the liquid reservoir 120 along the axial direction. The liquid guide 130 has two opposing sides (or end faces) along this axial direction, one side being completely in contact with the liquid reservoir 120, and the other side being in contact with the atomizing core assembly 200 under certain conditions. In still other examples, the liquid guide 130 is coaxially arranged with the liquid reservoir 120, and the length of the liquid guide 130 can also be greater than the length of the liquid reservoir 120. The portion longer than the liquid reservoir 120 is used to contact the atomizing core assembly 200 under certain conditions. In these embodiments, at least one side of the portion of the liquid guide 130 longer than the liquid reservoir 120 contacts the atomizing core assembly 200 to effectively establish an atomization matrix transport channel.

[0044] The liquid guiding element 130 can also be made of porous ceramic or porous fiber materials. Since the liquid reservoir 120 stores the atomizing matrix, and the liquid guiding element 130 guides the atomizing matrix, the volume of the liquid reservoir 120 is larger than that of the liquid guiding element 130. Furthermore, to store more atomizing matrix, its porous structure can be more porous and have a higher porosity compared to the liquid guiding element 130. To better guide the atomizing matrix, the porous structure on the liquid guiding element 130 should be more ordered and the pores more dense, so that the atomizing matrix can be guided and transported along a specific direction using its capillary effect.

[0045] The atomizer core assembly 200, as one of the core components of an electronic atomization device, is used to heat the atomization substrate to generate an aerosol. Specifically, when powered on, the atomizer core assembly 200 can heat the atomization substrate to atomize it and generate an aerosol. Please refer to [link / reference]. Figure 2The atomizing core assembly 200 includes an atomizing base 210 and a heating element 220 disposed on the atomizing base 210. The heating element 220 is electrically connected to the power supply assembly 300 and can generate heat after being powered on or supplied with power. After the liquid guide 130 and the heating element 220 come into contact, the atomizing matrix in the liquid storage container 120 is transferred to the heating element 220 through the guidance of the liquid guide 130. The heating element 220 can heat the atomizing matrix on the liquid guide 130, causing it to atomize and generate an aerosol. In some examples, the heating element 220 is a mesh structure composed of multiple heating wires, which can increase the contact area between the heating element 220 and the atomizing matrix to effectively and fully heat the atomizing matrix. Of course, in other examples, the heating element 220 can also be a heating ceramic with a porous structure.

[0046] The liquid reservoir 100 and the atomizing core assembly 200 are movable relative to each other, allowing the heating element 220 to selectively contact the liquid guide 130 provided in one of the at least two storage chambers 110. When the heating element 220 is in contact with the liquid guide 130, the heating element 220 can heat the atomizing matrix guided by the liquid guide 130 to generate an aerosol. This can also be understood as the user being able to switch between different flavors by moving the liquid reservoir 100 relative to the atomizing core assembly 200 or the atomizing core assembly 200 relative to the liquid reservoir 100, thereby activating the heating element 220 in the atomizing core assembly 200. Contact is made with the liquid guide 130 in the specific storage chamber 110 (the storage chamber 110 where the atomizing matrix that meets the user's taste or functional requirements is located) to meet the specific conditions mentioned above, thereby establishing a transmission channel for the atomizing matrix between the liquid storage chamber 100 and the atomizing core assembly 200, so as to complete the heating and atomization of the atomizing matrix in the storage chamber 110. When not needed, the contact between the heating element 220 and the liquid guide 130 in the specific storage chamber 110 can be cut off by the relative movement of the liquid storage chamber 100 and the atomizing core assembly 200, so as to separate the heating element 220 from the liquid guide 130.

[0047] By employing a structural design with at least two storage chambers 110 and one atomizing core assembly 200, the design of internal components and structures in electronic atomization devices is reduced, assembly difficulty and process requirements are lowered, and production costs are effectively reduced. Unlike atomizing core assemblies 200 where a liquid guiding structure contacts the storage chambers 110, potentially leaving residual atomizing matrix, at least two storage chambers 110 selectively engage with the atomizing core assembly 200 to generate aerosol. Furthermore, the atomizing core assembly 200 directly contacts the liquid guiding component 130 within each storage chamber 110 via the heating element 220. This means that when switching between different storage chambers 110, the liquid guiding component 130 also switches, ensuring that the aerosol generated after each heating and atomization corresponds to only one flavor and is unaffected by residual atomizing matrix. This effectively prevents flavor mixing, improves the aerosol's taste, and enhances the user experience.

[0048] Please continue reading. Figure 1 The electronic atomizing device also includes a support 700, an atomizing core assembly 200 mounted on the support 700, and a through-hole air outlet channel 170 in the liquid storage chamber 100. One end of the air outlet channel 170 is connected to the outside. After the heating element 220 heats the atomizing matrix on the liquid guiding component 130, the generated aerosol can pass through the heating element 220 of the atomizing core assembly 200 and enter the air outlet channel 170 from the side of the heating element 220 facing away from the liquid guiding component 130. The bracket 700 has a first air intake channel 710, and the atomizing base 210 has a second air intake channel 211. The first air intake channel 710 is also connected to the external environment. The second air intake channel 211 connects the first air intake channel 710 and the air outlet channel 170. When the heating element 220 and the liquid guide 130 are in contact and the user inhales, outside air enters the second air intake channel 211 along the first air intake channel 710 under negative pressure and carries the aerosol out through the air outlet channel 170 for the user to use. Alternatively, when the heating element 220 is separated from the liquid guide 130, the second air intake channel 211 blocks the connection between the first air intake channel 710 and the air outlet channel 170. At this time, no aerosol is generated at the heating element 220, and the aerosol cannot enter the air outlet channel 170 under the action of air. In some embodiments, the atomizing core assembly 200 is disposed between the bracket 700 and the liquid storage tank 100. The bracket 700 provides an installation base for the atomizing core assembly 200, so that a stable atomizing matrix transmission channel can be established between the atomizing core assembly 200 and the liquid storage tank 100.

[0049] In some embodiments, the atomizing base 210 has a hollowed-out portion, and the heating element 220 is disposed in the hollowed-out portion. The generated aerosol can be carried by the air entering the second air intake channel 211 along the first air intake channel 710 after passing through the heating element 220 and the hollowed-out portion opposite to the heating element 220, and then discharged from the electronic atomizing device after passing through the air outlet channel 170 and the mouthpiece 600 in sequence.

[0050] In some embodiments, at least two storage chambers 110 are arranged around the central axis OO of the air outlet channel 170, at least a portion of the atomizing core assembly 200 is disposed within one end of the air outlet channel 170, and at least one of the liquid reservoir 100 and the atomizing core assembly 200 is rotatable about the central axis OO, so that the heating element 220 can selectively correspond to the liquid guide 130 provided in one of the at least two storage chambers 110. Those skilled in the art should understand that the mode of movement includes movement (or translation) and rotation (or rotation). Although these embodiments limit at least one of the liquid reservoir 100 and the atomizing core assembly 200 to be rotatable about the central axis OO, the manner in which a single heating element 220 and the liquid guide 130 in at least two storage chambers 110 are in contact is not limited to the manner limited by the above embodiments. In some other examples, at least one of the liquid reservoir 100 and the atomizing core assembly 200 can also move relative to each other, or the liquid reservoir 100 and the atomizing core assembly 200 can both rotate and move.

[0051] Please see Figure 3 In some embodiments, the liquid reservoir 100 can rotate about the central axis OO relative to the atomizing core assembly 200 so that the heating element 220 can selectively correspond to the liquid guide 130 provided in one of the at least two storage cavities 110.

[0052] In some embodiments, the electronic atomizing device further includes an atomizing tube disposed inside the liquid storage chamber 100. The atomizing tube is a hollow structure with openings at both ends and defines the aforementioned air outlet channel 170. In these embodiments, the atomizing tube is a hollow cylindrical structure, and the atomizing tube and the liquid storage tank 100 are coaxially arranged. The outer wall of the atomizing tube and the liquid storage tank 100 cooperate to form at least two independent storage cavities 110. The liquid storage component 120 and the liquid guiding component 130 are both arc-shaped structures. The liquid storage component 120 and the liquid guiding component 130 are arranged sequentially along the radial direction of the atomizing tube. The liquid guiding component 130 is located close to the central axis OO of the atomizing tube, or in other words, the liquid guiding component 130 is attached to the outer wall of the atomizing tube. The atomizing core assembly 200 is located at one end of the atomizing tube. When the atomizing core assembly 200 or the liquid storage tank 100 rotates around the central axis OO of the atomizing tube, the heating element 220 of the atomizing core assembly 200 can correspond to different storage cavities 110 respectively, thereby enabling the switching of flavors.

[0053] Please continue reading. Figure 3In some embodiments, the inner surface of the liquid storage chamber 100 is provided with a liquid guiding opening 180, which corresponds to the atomizing core assembly 200. Liquid guiding components 130 are disposed near the inner surface of the liquid storage chamber 110, and one end of each liquid guiding component 130 near the atomizing core assembly 200 is blocked at the liquid guiding opening 180. The aerosol generated by the atomizing matrix on the liquid guiding component 130, which is in contact with the atomizing core assembly 200, can flow through the atomizing core assembly 200 into the air outlet channel 170. The liquid guiding opening 180 allows at least a portion of the liquid guiding component 130 to be exposed outside the liquid storage chamber 100, thus facilitating contact between the heating element 220 and the liquid guiding component. The shape of the liquid guiding opening 180 is not limited and can be circular, rectangular, triangular, polygonal, or other irregular shapes.

[0054] In some embodiments, one side of the liquid guide 130 is in contact with the liquid reservoir 110, and at least a portion of the other side is disposed at the liquid guide opening 180, for guiding the atomizing matrix in the liquid reservoir 110 to the heating element 220. Since at least a portion of the atomizing core assembly 200 is disposed within the air outlet channel 170, i.e., the atomizing core assembly 200 is arranged vertically (along the direction of the central axis OO of the air outlet channel 170), in order to better achieve contact between the heating element 220 and the liquid guide 130, the liquid guide opening 180 should extend through the end of the inner side of the liquid reservoir 110 along the direction of the central axis OO of the air outlet channel, i.e., the liquid guide opening 180 is an open-end structure. During use, the user can rotate the liquid reservoir 100 or the atomizing core assembly 200 as needed to bring the heating element 220 into contact with the liquid guide 130 disposed at the liquid guide opening 180.

[0055] In some embodiments, the liquid guide 130 has a first side 131 and a second side 132 arranged opposite to each other along the radial direction of the air outlet channel 170. The first side 131 is attached to the liquid storage member 120, and the second side 132 is attached to the inner sidewall of the liquid storage chamber 110. At least a portion of the second side 132 is disposed at the liquid guide opening 180 to form a contact surface, which is used to contact the heating element 220.

[0056] In other embodiments, the liquid storage chamber 100 and the atomizing core assembly 200 are arranged sequentially along the central axis OO of the air outlet channel 170. The liquid guide 130 is exposed in the storage cavity 110 through the liquid guide opening 180. The atomizing core assembly 200 is arranged laterally (along a direction perpendicular to the central axis OO) so that one end of it along the central axis OO is in contact with the liquid guide 130 to guide the atomizing matrix.

[0057] In other embodiments, at least two storage chambers 110 may also be arranged side by side along a direction perpendicular to the central axis OO of the air outlet channel 170. In this case, in the standby state (the state that can be heated after being powered on or supplied with power), the air outlet channel 170, the first air inlet channel 710 and the second air inlet channel 211 can always be in a connected state. The atomizing core assembly 200 is disposed at the end of the liquid storage chamber 100. The two can move relative to each other along the side-by-side arrangement, so that the heating element 220 selectively contacts the liquid guide 130 provided in one of the at least two storage chambers 110.

[0058] In some embodiments, the atomizing core assembly 200 is movably mounted on the bracket 700. The bracket 700 is provided with a first sliding part 720, and the atomizing seat 210 is provided with a second sliding part 212. The first sliding part 720 and the second sliding part 212 are movably connected. Through the cooperation of the first sliding part 720 and the second sliding part 212, the atomizing core assembly 200 can move stably relative to the bracket 700.

[0059] In some embodiments, the liquid storage chamber 100 can rotate about the central axis OO of the air outlet channel 170 so that the heating element 220 and the liquid guide 130 provided in one of the at least two storage chambers 110 are correspondingly arranged. The first sliding part 720 and the second sliding part 212 can slide relative to each other in a direction close to or away from the central axis OO, and drive the atomizing seat 210 to move in a direction close to or away from the central axis OO, so that the heating element 220 is attached to or separated from the corresponding liquid guide 130. When the liquid guide 130 and the heating element 220 are in contact, the liquid guide 130 guides the atomizing matrix on the liquid storage 120 to the heating element 220. The heating element 220 can heat the atomizing matrix in the liquid guide 130 to generate an aerosol. At this time, the second air inlet channel 211 connects the first air inlet channel 710 and the air outlet channel 170, and the aerosol can be discharged from the atomizing core assembly 200 through the air outlet channel 170. When the liquid guide 130 and the heating element 220 are separated, the transmission channel of the atomizing matrix between the liquid storage chamber 100 and the atomizing core assembly 200 is cut off. This can prevent the atomizing matrix from leaking through the transmission channel when the user is not using the electronic atomizing device. The second air inlet channel 211 blocks the connection between the first air inlet channel 710 and the air outlet channel 170, which can further prevent the atomizing matrix from leaking. By rotating the liquid storage chamber 100 and moving the atomizing base 210 along the direction close to or away from the central axis OO, different flavors can be flexibly switched, and cross-contamination of flavors can be avoided. In this structural design, an air outlet channel 170 is formed inside the liquid storage chamber 100, and different storage chambers 110 are arranged around the outside of the air outlet channel 170. The atomizing core assembly 200 is set in one end of the air outlet channel 170, which can effectively optimize the structural layout inside the electronic atomizing device and help reduce the overall volume of the electronic atomizing device. It should be understood that the method of switching between different flavors or functions in this embodiment is based on the setting position of the atomizing core assembly 200. The liquid storage chamber 100 is rotated so that the storage cavity 110 corresponds to the position of the atomizing core assembly 200. Then, the atomizing core assembly 200 is moved to achieve the contact or separation of the heating element 220 and the liquid guide 130. Based on this, the moving direction of the atomizing seat 210 is any direction on the plane perpendicular to the central axis OO of the atomizing tube, including the radial direction of the air outlet channel 170, the direction parallel to the diameter of the air outlet channel 170, or the tangential direction around the central axis OO of the air outlet channel 170, as long as its moving requirements are met. For ease of description, this direction is defined as the first direction X.

[0060] In some embodiments, the first direction X is parallel to the diameter of the air outlet channel 170. The atomizing core assembly 200 can move relative to the support 700 along the first direction X, causing the atomizing seat 210 to move closer to or away from the liquid guide member 130, and causing the heating element 220 to adhere to or separate from the liquid guide member 130. In these embodiments, at least one of the first sliding portion 720 and the second sliding portion 212 extends along the first direction X, thereby stably guiding the atomizing seat 210 closer to or away from the liquid guide member 130 along the first direction X, causing the heating element 220 to adhere to or separate from the liquid guide member 130. Specifically, one of the first sliding portion 720 and the second sliding portion 212 is a slider, and the other is a linear groove. Please refer to [link to relevant documentation]. Figure 2 and Figure 4 The first sliding portion 720 on the bracket 700 is a straight groove extending along the first direction X, and the second sliding portion 212 is a slider that cooperates with the straight groove. The slider can be a block structure or a strip structure extending along the first direction X. When the slider is a strip structure, the extension length of the slider (length in the first direction X) is less than the extension length of the straight groove (length in the first direction X) to provide sufficient translation space for the atomizer base 210. In order to improve the stability of the translation of the atomizer core assembly 200 relative to the bracket 700, two of each of the first sliding portions 720 and the second sliding portion 212 are provided. The two first sliding portions 720 are symmetrically arranged on the bracket 700 along the direction perpendicular to the first direction X (which is also on a plane perpendicular to the central axis OO of the atomizer tube), and the second sliding portions 212 are symmetrically arranged on the atomizer base 210 along the direction perpendicular to the first direction X.

[0061] Please continue reading. Figure 4 The bracket 700 is provided with an installation cavity 730, and the first sliding part 720 is disposed on the cavity wall of the installation cavity 730. The end of the atomizing seat 210 away from the atomizing tube is disposed in the installation cavity 730, so that the second sliding part 212 and the first sliding part 720 are movable and cooperate.

[0062] The switching component 500 is a key component for switching between different flavors or implementing different functions. It can also be used to drive the liquid storage tank 100 or the atomizing core assembly 200 to move, thereby making the heating element 220 fit with the liquid guide 130 in the corresponding storage cavity 110. In some embodiments, the switching component 500 is used to drive the atomizing base 210 to move in a direction close to or away from the liquid guide 130. That is, after the liquid storage tank 100 is rotated into place, the switching component 500 drives the atomizing base 210 to move in the first direction X, so that the heating element 220 and the liquid guide 130 fit together. After use, the switching component 500 drives the atomizing base 210 to move, so that the heating element 220 and the liquid guide 130 separate.

[0063] Please continue reading. Figure 4The switching component 500 includes a driving member 510 and an elastic member 520. One end of the driving member 510 and one end of the elastic member 520 are respectively connected to the atomizing base 210. One end of the driving member 510 extends out of the electronic atomizing device for operation. The elastic member 520 is used to apply an elastic restoring force to the atomizing base 210 to move closer to the liquid guide member 130. In some embodiments, the elastic member 520 extends along a first direction X and one end is connected to the support 700. The driving member 510 can drive the atomizing base 210 to move away from the liquid guide member 130 in the first direction X, and the elastic member 520 has an elastic restoring force that drives the atomizing base 210 to move closer to the liquid guide member 130 in the first direction X. Specifically, when switching between different flavors or functions, the driving component 510 drives the atomizing base 210 to move away from the liquid guide 130 in the first direction X, causing the heating element 220 to separate from the liquid guide 130. At this time, the elastic component 520 is in a compressed state and has an elastic restoring force that drives the atomizing base 210 closer to the liquid guide 130. The user rotates the liquid storage chamber 100, and after it is rotated to the correct position, the elastic component 520 drives the atomizing base 210 closer to the liquid guide 130, causing the heating element 220 and the liquid guide 130 to fit together, so that the aerosol generated by the atomizing matrix in the corresponding storage cavity 110 can be obtained after power is applied. In some examples, the elastic component 520 is a spring or elastic cord. In some examples, the drive element 510 serves only as a point of leverage for the user to move the atomizer base 210. One end of the drive element 510 is connected to the atomizer base 210, and the other end extends to the outside of the electronic atomizing device through the movable hole 430 on the housing assembly 400, so that the user can manually move the atomizer base 210 using the drive element 510. In other examples, the drive element 510 can be an electric structure such as a motor, which the user can use to automatically move the atomizer base 210 by activating its switch.

[0064] In some embodiments, the liquid storage chamber 100 is provided with a first locking part 140 and the atomizing seat 210 is provided with a second locking part 213. When the heating element 220 is in contact with the liquid guide 130, the first locking part 140 and the second locking part 213 are locked, restricting the relative movement of the atomizing core assembly 200 between two adjacent storage cavities 110 of the liquid storage chamber 100.

[0065] Due to the elastic element 520, it can use its elastic restoring force to move the atomizing seat 210. In order to effectively ensure the stable contact between the heating element 220 and the liquid guiding element 130 during the operation of the electronic atomizing device, and to effectively ensure sufficient atomizing matrix and avoid dry burning caused by insufficient atomizing matrix, a first locking part 140 is provided on the liquid storage chamber 100 and a second locking part 213 is provided on the atomizing seat 210. The two work together to fix the positions of the atomizing seat 210 and the heating element 220.

[0066] One of the first locking part 140 and the second locking part 213 can be a protrusion and the other a groove. The protrusion and the groove engage to achieve fixation, and the engagement of the protrusion and the groove simplifies the locking method and structure. That is, locking can be achieved when the atomizing seat 210 is close to the liquid guide 130. In some examples, the number of first locking parts 140 is the same as that of the storage chambers 110, that is, the first locking parts 140 and the storage chambers 110 are arranged in a one-to-one correspondence and are evenly distributed around the central axis OO of the atomizing tube. By rotating the liquid storage chamber 100, different storage chambers 110 can be switched. By utilizing the engagement of the first locking parts 140 and the second locking parts 213 corresponding to the storage chambers 110, relative rotation between the liquid storage chamber 100 and the atomizing core assembly 200 can be avoided. It can also ensure that when heating the corresponding atomizing matrix in the storage chamber 110, the heating element 220 and the liquid guide 130 therein are in contact.

[0067] Please continue reading. Figures 1 to 3 The first locking part 140 is a groove provided on the inner wall of the liquid storage chamber 100. The number and position of the grooves correspond to the storage cavity 110. The interior of the liquid storage chamber 100 between the grooves forms an abutment part 160. The second locking part 213 is a protrusion. In this schematic diagram, the electronic atomizing device is in working or standby mode (it can generate aerosol after being powered on). The heating element 220 and the liquid guide 130 are attached to each other. The second locking part 213 is inserted and fixed in the first locking part 140. Specifically, in standby or working state, the heating element 220 of the atomizer core assembly 200 and the liquid guide 130 in one of the storage chambers 110 are in contact, and the protrusion is also locked in the corresponding groove of the storage chamber 110. At this time, the liquid reservoir 100 and the atomizer core assembly 200 cannot move relative to each other. Without applying external force, the heating element 220 and the liquid guide 130 are also stably in contact. When it is necessary to switch between different storage chambers 110, the user applies external force to the drive component 510 to drive the atomizer base 210 away from the liquid guide 130. This causes the heating element 220 and the liquid guiding component 130 to separate. At this time, the elastic component 520 is in a compressed state, and the protrusion also exits the groove. When the user rotates the liquid storage chamber 100, the protrusion abuts against the abutment part 160 during the rotation (at this time, the force applied to the driving component 510 can be canceled). When rotating to switch to the adjacent storage chamber 110, the protrusion rotates to the groove. At this time, under the action of the elastic component 520, the protrusion is inserted into the groove, and the user can no longer rotate the liquid storage chamber 100. When it is necessary to continue rotating and switching, the above actions can be repeated.

[0068] In some embodiments, the first locking portion 140 and the second locking portion 213 are interference-fitted, and at least one of the second locking portion 213 and the first locking portion 140 may be made of an elastic material, which helps to achieve locking and separation of the two, and can reduce frictional wear between the first locking portion 140 and the abutment portion 160 of the liquid storage tank 100 during rotation.

[0069] The housing assembly 400 provides an installation base and housing space for the power supply assembly 300, meaning the power supply assembly 300 is housed within the housing assembly 400. The housing assembly 400 and the liquid storage tank 100 are detachably connected, providing both an installation base and a movable base for the liquid storage tank 100. The bracket 700 is housed within the power supply assembly 300, and the atomizing core assembly 200 is mounted on the bracket 700, ensuring that at least a portion of the atomizing core assembly 200 is housed within the housing assembly 400. The liquid storage tank 100 has a first mating part 150, and the housing assembly 400 has a second mating part 410. The first mating part 150 and the second mating part 410 are movably engaged, allowing the liquid storage tank 100 and the atomizing core assembly 200 to move relative to each other.

[0070] Please continue reading. Figure 3 and Figure 4 as well as Figure 5 The second mating part 410 is disposed on the inner wall of the housing assembly 400 near the liquid storage tank 100. The second mating part 410 is a mating protrusion protruding inward (inward in the direction towards the central axis OO). The first mating part 150 is disposed on the outer wall of the liquid storage tank 100 near the housing assembly 400. The first mating part 150 is a mating groove disposed on the outer wall of the liquid storage tank 100. After the mating groove is engaged with the mating protrusion, it can improve the rotation guidance when the liquid storage tank 100 rotates relative to the housing assembly 400. In some examples, the mating protrusion is an annular protrusion, and the mating groove is an arc-shaped groove with the center of the liquid storage tank 100 as the center. The number of mating grooves is the same as the number of storage cavities 110, that is, at least two mating grooves are provided, and the at least two mating grooves are evenly and spaced around the central axis OO. In some examples, the component with the second mating part 410 is detachably connected to the housing assembly 400. For ease of description, it is defined as a locking element. One end of the locking element is detachably disposed on the inner wall of the housing assembly 400 near the liquid storage tank 100, and the other end protrudes inward (toward the direction of the central axis OO) to form the second mating part 410.

[0071] In some embodiments, the bracket 700 and the housing assembly 400 are snap-fitted together. Specifically, one of the housing assembly 400 and the bracket 700 has a snap-fit ​​protrusion 740, and the other has a snap-fit ​​groove 420. To improve the stability of the connection, multiple snap-fit ​​protrusions 740 and multiple snap-fit ​​grooves 420 are provided. The multiple snap-fit ​​protrusions 740 and multiple snap-fit ​​grooves 420 are evenly distributed around the axis of the housing assembly 400, and the snap-fit ​​protrusions 740 and snap-fit ​​grooves 420 are snapped together one-to-one to achieve a stable connection between the housing assembly 400 and the bracket 700. Please refer to [link to relevant documentation]. Figure 6 The inner wall of the housing assembly 400 is provided with a snap-fit ​​groove 420 and the upper snap-fit ​​protrusion 740 of the bracket 700.

[0072] In some embodiments, the bracket 700 not only provides a mounting base for the atomizing core assembly 200, but also provides a mounting base for the power supply assembly 300. The power supply assembly 300 is disposed inside the housing assembly 400 via the bracket 700. The power supply assembly 300 and the atomizing core assembly 200 are respectively disposed on both sides of the bracket 700 and are electrically connected to the atomizing core assembly 200 for supplying power to the atomizing core assembly 200.

[0073] Please continue reading. Figure 6 In some embodiments, the power supply component 300 includes a battery 310, a circuit board 320, and an airflow sensor 330. The battery 310 is used to supply power, and the battery 310 and the circuit board 320 are electrically connected to each other. The circuit board 320, the airflow sensor 330, and the atomizing core assembly 200 are electrically connected to each other.

[0074] In some embodiments, the bracket 700 is provided with a positioning groove 750, and the two sides of the circuit board 320 are engaged in the positioning groove 750. The bracket 700 is also provided with an electrode 760, which is used to achieve a conductive connection between the circuit board 320 and the heating element 220 of the atomizing core assembly 200. The bracket 700 also has a mounting hole 770 on the side facing away from the atomizing core assembly 200 for mounting an airflow sensor 330. The airflow sensor 330 is conductively connected to the circuit board 320. When the user inhales, the airflow sensor 330 converts the monitored airflow (pressure) information into an electrical signal and transmits it to the circuit board 320. The circuit board 320 triggers the heating element 220 to start heating based on this electrical signal. It should be understood that the working principle of the airflow sensor 330 is to monitor changes in airflow (pressure) during inhalation. Therefore, the mounting hole 770 can be connected to any part of the airflow channel formed by the outlet channel 170, the first inlet channel 710, and the second inlet channel 211 to achieve this function. Figure 1 As shown, the mounting hole 770 communicates with the air outlet passage 170 through the gap between the liquid reservoir 100 and the bracket 700. In other examples, the mounting hole 770 may also communicate with the first air inlet passage 710 or the second air inlet passage 211.

[0075] In some embodiments, the airflow sensor 330 has a sensing surface 331 and a mounting surface 332. The sensing surface 331 is in communication with the air outlet channel 170, and a sealing sleeve 334 is fitted onto the mounting surface 332 so that the sensing surface 331 of the airflow sensor 330 has no other path to communicate with the outside world except through the hole communicating with the air outlet channel 170, thus ensuring that the sensing surface 331 is sealed within the mounting hole 770. In these embodiments, a wire 333 is also provided on the mounting surface 332 to achieve a conductive connection with the circuit board 320.

[0076] Please see Figure 7In some embodiments, the atomizing core assembly 200 further includes a conductive portion 230, which is used to achieve a conductive connection between the heating element 220 and the power supply assembly 300. The conductive portion 230 includes a conductive body 231 and a bent portion 232. The conductive body 231 extends from one end of the atomizing base 210 to the other end and is connected to the bent portion 232, so that when the atomizing base 210 is installed on the bracket 700, the bent portion 232 contacts the electrode 760 to achieve a conductive connection. The bent portion 232 is also provided in the middle section of the conductive body 231 and at the end facing away from the bracket 700. The bent portion 232 is engaged with the atomizing base 210 to fix the conductive portion 230 and the heating element 220.

[0077] The nozzle 600 is used for users to aspirate aerosols. The nozzle 600 is located at the outlet end of the outlet channel 170, and its interior has a suction channel 610 communicating with the outlet channel 170. In some examples, for ease of cleaning, the nozzle 600 and the liquid reservoir 100 are detachably connected. The end of the nozzle 600 facing the liquid reservoir 100 has a coaxially arranged first insertion portion 620 and second insertion portion 630. The first insertion portion 620 is located inside the second insertion portion 630 and is inserted into the atomizing tube. The second insertion portion 630 is inserted into the liquid reservoir 100. To effectively ensure a seal, a sealing ring 640 is provided between the second insertion portion 630 and the liquid reservoir 100, and a sealing element 650 is provided between the first insertion portion 620 and the atomizing tube. Both the sealing ring 640 and the sealing element 650 can be made of silicone or rubber.

[0078] 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.
