Description

Technical Field

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

[0002] The atomizer coil of an electronic atomizer heats the e-liquid after being powered on, atomizing it for the user. During heating, the viscosity of the e-liquid decreases to some extent, increasing its fluidity. Simultaneously, the air inside the electronic atomizer expands due to the heating, increasing the internal pressure. Under this increased pressure, the lower viscosity e-liquid tends to flow into the atomizer coil at a faster rate, potentially leading to leakage at the coil. Utility Model Content

[0003] This application provides an atomizing core, an atomizer, and an electronic atomizing device to solve the problem of leakage of atomizing liquid during the heating process.

[0004] In one embodiment, an atomizing core is provided, comprising:

[0005] The core shell has at least one liquid inlet hole;

[0006] A liquid guiding channel is formed inside the core shell; at least one of the liquid inlet holes is connected to the liquid guiding channel and an external liquid respectively;

[0007] A liquid guiding assembly, abutting against the inner wall of the core shell, includes at least one liquid reservoir; at least one liquid reservoir has a capillary channel, the liquid guiding channel being in liquid guiding communication with the capillary channel; and

[0008] An atomizing component abuts against the inner wall of at least one of the liquid storage components; the atomizing component has an atomizing channel, and along the airflow direction in the atomizing channel, the liquid inlet is opened at the end of at least one of the liquid storage components corresponding to the upstream end of the atomizing channel.

[0009] In some embodiments, the liquid guiding channel is located circumferentially within the core shell and at the end of at least one of the liquid storage components corresponding to the upstream end of the atomizing channel; at least one of the liquid inlet holes is located on the outer periphery of the liquid guiding channel.

[0010] In some embodiments, the core shell includes a hollow shell and a seat disposed at the open end of the shell; one end of the seat near the shell, together with the shell and at least one of the liquid storage components, defines the liquid guiding channel, and the shell and the liquid guiding channel define at least one of the liquid inlet holes; the liquid guiding assembly and the atomizing assembly are disposed inside the shell.

[0011] In some embodiments, the seat includes a body and a first seal; the first seal is interference-fitted between the body and the housing; the outer diameter of the end of the first seal near at least one of the liquid reservoirs is smaller than the outer diameter of at least one of the liquid reservoirs, and defines a liquid channel forming the liquid channel.

[0012] In some embodiments, the atomizing assembly includes a heating element and at least two connecting electrodes electrically connected to the heating element; the heating element is disposed on the liquid storage container; at least two connecting electrodes are disposed on the base and spaced apart from each other; at least a portion of each connecting electrode is exposed at the end of the base away from the housing.

[0013] In some embodiments, the diameter of the liquid inlet hole is greater than or equal to 0.6 mm and less than or equal to 3 mm.

[0014] In some embodiments, the liquid storage device includes a first liquid storage device and a second liquid storage device, the first liquid storage device being sleeved outside the second liquid storage device, and the capillary channels defined by the two are in communication; the liquid channel is in communication with the capillary channel defined by the first liquid storage device.

[0015] In some embodiments, the liquid guiding assembly further includes a liquid guiding element, which is radially sleeved between the first liquid storage element and the second liquid storage element and defines at least one liquid guiding hole; the capillary channel of the first liquid storage element and the capillary channel of the second liquid storage element are in liquid guiding communication through at least one of the liquid guiding holes.

[0016] An atomizer is provided, comprising the atomizing core as described in any of the preceding embodiments; the atomizer defines a liquid storage chamber, and the at least one liquid inlet is in liquid-guiding communication with the liquid storage chamber.

[0017] An electronic atomizing device is provided, comprising the atomizing core described in any of the foregoing embodiments; the electronic atomizing device defines a liquid storage chamber, and the at least one liquid inlet is in liquid-guiding communication with the liquid storage chamber.

[0018] According to the atomizing core, atomizer, and electronic atomizing device of the above embodiments, by setting the liquid inlet hole at the end of the at least one liquid storage component corresponding to the upstream end of the atomization channel, the liquid inlet hole and the capillary channel defined by the liquid storage component in the liquid guiding assembly can be misaligned. This prevents the liquid matrix from directly entering the capillary channel of the liquid guiding assembly through the liquid inlet hole, thereby reducing the liquid inlet velocity of the atomizing liquid to a certain extent, matching the capillary liquid guiding velocity of the liquid storage component, and reducing atomizing liquid leakage. By setting the liquid guiding channel, the conduction path of the atomizing liquid in the atomizing core can be extended, reducing the conduction velocity of the atomizing liquid during heating and atomization, thereby controlling the total amount of atomizing liquid in the atomizing core and preventing leakage caused by the liquid guiding velocity exceeding the atomization velocity. By setting the liquid storage component with numerous capillary channels, the capillary properties such as capillary force of the capillary channels can be used to achieve absorption and conduction of the atomizing liquid, further preventing the occurrence of atomizing liquid leakage problems.

Detailed Implementation

[0024] 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.

[0025] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0026] 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. Unless otherwise specified, the terms "connection" and "linkage" used in this application include both direct and indirect connections (linkages).

[0027] like Figures 1 to 3 As shown, this application provides an atomizing core 1, which can heat and atomize an atomizing liquid after being powered on for user use. The atomizing core 1 may include a core shell 10, an atomizing component 20, and a liquid guiding component 30. The atomizing component 20 and the liquid guiding component 30 are respectively disposed within the core shell 10. The core shell 10 defines at least one liquid inlet hole 111, which can communicate with the outside for connecting to an external liquid storage chamber to conduct the atomizing liquid to the liquid guiding component 30 within the core shell 10. The liquid guiding component 30 is used to conduct the atomizing liquid flowing into the liquid inlet hole 111 to the atomizing component 20. The atomizing component 20 is used to heat and atomize the surrounding atomizing liquid after being powered on.

[0028] Specifically, the core shell 10 also has a liquid guiding channel 100, which can communicate with the liquid inlet 111 and the liquid guiding assembly 30 respectively, for guiding the atomizing liquid flowing in from the liquid inlet 111 to the liquid guiding assembly 30. The liquid guiding assembly 30 abuts against the inner wall of the core shell 10 and includes at least one liquid storage element with numerous capillary channels. The liquid guiding channel 100 can communicate with the numerous capillary channels in the liquid storage element. The atomizing assembly 20 abuts against the inner wall of the liquid storage element and has an atomizing channel 200. The atomizing liquid passes sequentially through the liquid inlet 111, the liquid guiding channel 100, and the capillary channels in the liquid storage element to the periphery of the atomizing assembly 20, where it is heated and atomized. The heated and atomized matrix can flow out of the atomizing core 1 through the atomizing channel 200 for user use.

[0029] By setting up a liquid guiding channel 100, this application can prevent the atomized liquid from being directly conducted to the capillary channel through the liquid inlet 111, thus extending the conduction path of the atomized liquid within the atomizing core 1. This extended liquid guiding path can reduce the conduction speed of the atomized liquid to some extent during the heating and atomization process, thereby controlling the total amount of atomized liquid within the atomizing core 1 and preventing leakage due to the liquid guiding speed exceeding the atomization speed.

[0030] This application, by setting up a liquid storage device with numerous capillary channels, can achieve the absorption and conduction of atomized liquid through the capillary properties such as capillary force of the capillary channels, thereby further avoiding the problem of atomized liquid leakage.

[0031] It is important to understand that the material selection for the liquid reservoir can depend on the physical properties of the atomizing liquid. For example, it can be made of porous materials, including but not limited to cotton-like materials (such as natural cotton and / or synthetic cotton) or inorganic porous materials (such as ceramics, fiber materials, etc.). Liquid reservoirs made of different materials can be used to adapt to the physical properties of different liquid matrices, such as density, viscosity, surface tension, and vapor pressure, so a flexible selection is possible and no specific limitations are made here.

[0032] like Figure 1 As shown, the core shell 10 can be a hollow cylinder, with the liquid guiding component 30 and the atomizing component 20 coaxially arranged inside the core shell 10. Of course, the core shell 10 can also be configured as a polygonal column, an elliptical column, an irregular column, a sphere, an ellipsoid, an irregular shape, or other shapes.

[0033] Specifically, the core shell 10 includes a shell 11 and a base 12. The shell 11 is a hollow cylindrical shape with openings at both ends along its axial direction to facilitate gas flow. The atomized liquid is carried out by the airflow through the user's suction. The base 12 is located at one of the open ends of the shell 11 to prevent internal components such as the liquid guiding assembly 30 and the atomizing assembly 20 from detaching from that end.

[0034] The diameter of the end of the housing 11 away from the base 12 can be slightly smaller than the diameter of the end connected to the base 12, so as to prevent the internal components from coming out of the open end, and at the same time facilitate the assembly of the atomizing core 1 in the electronic atomizing device.

[0035] Furthermore, at least one air inlet 1211 can be defined on the base 12, and the two ends of the atomizing channel 200 can be connected to the air inlet 1211 and the opening end of the housing 11 away from the base 12, respectively. The atomizing component 20 is at least partially exposed in the atomizing channel 200 so that the atomized liquid matrix is ​​located within the atomizing channel 200 and can flow out with the user's inhalation.

[0036] like Figure 2 As shown, in some embodiments, the liquid inlet 111 is formed at the end of at least one liquid reservoir in the liquid guiding assembly 30 along the airflow direction within the atomizing channel 200. Furthermore, along the airflow direction of the atomizing channel 200, the liquid inlet 111 is formed at the end of at least one liquid reservoir corresponding to the upstream end of the atomizing channel 200.

[0037] This design allows the inlet hole 111 to be misaligned with the capillary channel defined by the liquid storage component within the liquid guiding assembly 30, preventing the liquid matrix from directly entering the capillary channel of the liquid guiding assembly 30 through the inlet hole 111. Furthermore, this reduces the inlet velocity of the atomizing liquid to match the capillary guiding velocity of the liquid storage component, thus minimizing leakage of the atomizing liquid.

[0038] like Figure 2 As shown, in some embodiments, the liquid guiding channel 100 can be arranged circumferentially on the core shell 10 and located at the end of at least one liquid storage element corresponding to the upstream end of the atomizing channel 200. The liquid inlet 111 can be provided on the outer peripheral side of the liquid guiding channel 100.

[0039] This configuration allows for flow direction redirection of the atomizing liquid within the atomizing core 1. By positioning the liquid inlet 111 on the outer periphery of the liquid guiding channel 100, the direction of the atomizing liquid flowing through the liquid inlet 111 into the liquid guiding channel 100 is approximately perpendicular to the axial direction of the atomizing core 1. Similarly, by positioning the liquid guiding channel 100 at one end of the liquid guiding assembly 30, the direction of the atomizing liquid flowing through the liquid guiding channel 100 into the liquid guiding assembly 30 is approximately along the axial direction of the atomizing core 1.

[0040] Compared to linearly conductive atomizing fluid, by changing the direction of atomization within the atomizing core 1, the conduction speed of the atomizing fluid can be further reduced, thereby further preventing leakage.

[0041] Furthermore, the number of liquid inlet holes 111 can be at least two, for example, three, four, five, or more. They can be evenly spaced on the outer periphery of the liquid guiding channel 100 to facilitate uniform circumferential liquid guiding through the liquid guiding channel 100. In turn, the liquid guiding channel 100 can uniformly conduct the atomizing liquid through the liquid guiding assembly 30, ensuring the uniformity of axial liquid conduction and atomization, and guaranteeing the user's inhalation experience.

[0042] In some embodiments, the liquid guiding assembly 30 is located within the housing 11. The liquid guiding channel 100 may be located at one end of the liquid guiding assembly 30 near the seat 12, and may be defined by the housing 11, the seat 12, and at least one liquid reservoir.

[0043] Specifically, one end of the housing 11 connected to the seat 12 can be sleeved on at least part of the seat 12 and define an inlet hole 111 corresponding to the liquid guiding channel 100, so that the inlet hole 111 is located on the outer periphery of the liquid guiding channel 100.

[0044] Continue reading Figure 2 In some embodiments, the outer periphery of the seat 12 near the liquid guiding assembly 30 is recessed inward to form a liquid guiding groove 1221, such that the outer diameter of the end of the seat 12 near the liquid guiding assembly 30 is smaller than the outer diameter of the liquid guiding assembly 30. The top and outer periphery of the liquid guiding groove 1221 are both through-holes. The top side can be blocked by at least one liquid storage component of the liquid guiding assembly 30, and the outer periphery can be blocked by the housing 11, thereby forming a liquid guiding channel 100. The end of the liquid guiding channel 100 facing the inside of the housing 11 can communicate with the capillary channel of the liquid storage component.

[0045] In some embodiments, the seat 12 may include a body 121 and a first seal 122. The first seal 122 may be interference-fitted between the body 121 and the housing 11 to seal the gap at the connection point and prevent leakage of the atomizing liquid. The liquid guiding groove 1221 may be formed on the outer periphery of the first seal 122 near the end of the liquid guiding assembly 30.

[0046] By placing the liquid guide groove 1221 on the first seal 122, the relative sealing of the liquid guide channel 100 can be ensured, and leakage can be avoided when the atomized liquid flows through the liquid guide channel 100.

[0047] It should be understood that the assembly between the base 12 and the housing 11 can be achieved solely through the interference fit between the first seal 122 and the body 121 and the housing 11, respectively. Alternatively, the body 121 can also be simultaneously connected to the housing 11 through threaded connections, snap-fit ​​connections, interference fits, or other methods to further improve the stability of the assembly.

[0048] In some other embodiments, the liquid channel 1221 may also be formed on the body 121.

[0049] In some other embodiments, the body 121 can be connected to the housing 11 through a sealing process such as integral molding, threaded connection, or interference fit. In this embodiment, the seat 12 may also consist only of the body 121.

[0050] In some other embodiments, the liquid guiding channel 100 and the liquid inlet hole 111 may be located on the core shell 10 at one end of the liquid guiding assembly 30 away from the base 12.

[0051] In some embodiments, the diameter of the liquid inlet 111 can be greater than or equal to 0.6 mm and less than or equal to 3 mm. For example, its diameter can be selected as 0.8 mm, 1 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, 2 mm, 2.2 mm, 2.4 mm, 2.6 mm, 2.8 mm, or any other value within this range.

[0052] By setting the aperture of the liquid inlet 111, the liquid guiding speed can be further controlled. In conjunction with the setting of the liquid guiding path, the flow rate of the atomized liquid during the suction process can be controlled to avoid leakage.

[0053] It should be understood that the diameter of the liquid inlet 111 can be flexibly set according to the viscosity of the atomizing liquid, the rated atomization speed of the atomizing component 20, the size of the electronic atomizing device, etc., so no further limitation is made here.

[0054] In some embodiments, the liquid storage device having numerous capillary channels may include a first liquid storage device 32 and a second liquid storage device 33. Both the first liquid storage device 32 and the second liquid storage device 33 are tubular, with the first liquid storage device 32 sleeved over the second liquid storage device 33, and both filling the hollow space within the core shell 10. The internal space of the second liquid storage device 33 can be considered as the atomizing channel 200.

[0055] Specifically, the inner wall of the first liquid storage component 32 can at least partially conform to the outer wall of the second liquid storage component 33, so that their respective capillary channels are in communication. The liquid guiding channel 100 can be located at one end of the first liquid storage component 32 near the base 12 and is in communication with the capillary channel of the first liquid storage component 32. The atomizing component 20 can be at least partially disposed inside the second liquid storage component 33. During the user's inhalation process, the atomized liquid can flow sequentially through the inlet hole 111, the liquid guiding channel 100, the capillary channel of the first liquid storage component 32, and the capillary channel of the second liquid storage component 33 to the periphery of the atomizing component 20, where it is heated and atomized.

[0056] It should be understood that the materials used in the first liquid storage component 32 and the second liquid storage component 33 may be the same or different, and the porosity and / or pore size of the porous materials used may be the same or different, without specific limitations.

[0057] Continue reading Figure 2 In some embodiments, the liquid guiding assembly 30 may further include a liquid guiding element 31. The liquid guiding element 31 may be tubular and may be coaxially disposed between the first liquid reservoir 32 and the second liquid reservoir 33. The liquid guiding element 31 may define at least one liquid guiding hole 311 for allowing the first liquid reservoir 32 and the second liquid reservoir 33 to fit together, so that their capillary channels are connected for liquid guiding.

[0058] The liquid guiding component 31 can improve the structural strength of the liquid guiding assembly 30, and can also precisely control the liquid guiding path, prevent blockage, optimize liquid distribution, reduce liquid transmission speed and reduce liquid backflow, which helps to improve the performance and service life of the atomizing core 1.

[0059] Specifically, the number of liquid guiding holes 311 can be set to multiple, and they can be evenly spaced along the circumference of the liquid guiding member 31 so that the atomized liquid can be evenly distributed in the circumference of the liquid guiding assembly 30.

[0060] In some embodiments, the axial lengths of the first liquid reservoir 32 and the second liquid reservoir 33 can both be less than the axial length of the liquid guide 31. One end of the liquid guide 31 can be inserted into the base 12, and the other end can be inserted into the opening of the housing 11 away from the base 12, so as to achieve positioning between the liquid guide 31 and the core housing 10 and improve the stability of the liquid guide assembly 30 in the core housing 10.

[0061] It should be understood that the lengths of the first liquid storage component 32 and the second liquid storage component 33 along the axial direction can be the same or different, and no specific limitation is made here.

[0062] Furthermore, one end of the liquid guiding member 31 can be disposed circumferentially between the first sealing member 122 and the body 121, or between the first sealing member 122 and the housing 11, so as to seal the gap between the end of the liquid guiding member 31 and the core shell 10.

[0063] The core shell 10 may also include a second sealing element 13, which may be disposed at the open end of the shell 11 away from the seat 12 and is circumferentially interference-fitted between the shell 11 and the liquid guide 31 to seal the gap between the shell 11 and the liquid guide 31, thereby further preventing leakage of the atomizing liquid.

[0064] It should be understood that the first seal 122 and the second seal 13 can be made of materials with certain elasticity and stable material properties, such as silicone and rubber, without any specific limitations.

[0065] like Figure 2 and Figure 3 As shown, in some embodiments, the atomizing assembly 20 may include a heating element 21 and at least two electrode leads 23. The heating element 21 may be disposed inside the second liquid reservoir 33 and is used to generate heat after being connected to a power source to atomize the surrounding liquid. The at least two electrode leads 23 may be electrically connected to the heating element 21 respectively for connecting to an external power source to supply power to the heating element 21.

[0066] Specifically, the electrode lead 23 can extend through the atomization channel 200 to the base 12, and be led out through the base 12 to be connected to an external power source.

[0067] It should be understood that the electrode lead 23 can be a flexible wire or a rigid conductive post, etc., without specific limitations.

[0068] In some embodiments, the atomizing component 20 may further include at least two connecting electrodes 22, which are disposed on the end face of the base 12 away from the housing 11 and are electrically connected to the heating element 21 through electrode leads 23 for use as an external power source.

[0069] Specifically, please refer to the following: Figure 1 The connecting electrode 22 can be disposed on the body 121, and at least partially exposed on the end face of the body 121 away from the housing 11. Some of the connecting electrodes 22 can be annular, so that all the connecting electrodes 22 can be nested one at a time.

[0070] The location and shape of the connecting electrode 22 facilitate electrical connection between the atomizer core 1 and other electronic components within the electronic atomizing device. During assembly, there is no need to consider whether the assembly angle allows for electrical connection, nor is any special electrical connection operation required. The atomizer core 1 can be directly assembled into the electronic atomizing device without regard to the circumferential angle. The electronic components within the electronic atomizing device supply power to the atomizer core 1 by electrically connecting to the connecting electrode 22.

[0071] It should be understood that the body 121 can be made of an insulating material to achieve mutual insulation between at least two connecting electrodes 22. Of course, it can also be composed of a conductive material coated with an insulating layer, etc.

[0072] It should be understood that the connecting electrode 22 can be disposed on the body 121, and at least partially exposed on the end face of the body 121 opposite to the housing 11. The connecting electrode 22 can be plate-shaped and attached to the end face of the body 121 opposite to the housing 11, with the electrode lead 23 passing through the body 121 and electrically connected to the connecting electrode 22. Alternatively, the connecting electrode 22 can be tubular or columnar with a certain thickness, penetrating axially through the body 121, with the electrode lead 23 directly electrically connected to the connecting electrode 22 within the core shell 10. No specific limitations are made here.

[0073] It should be understood that some of the connecting electrodes 22 are annular, and all the connecting electrodes 22 are spaced apart. This can be because one connecting electrode 22 is cylindrical or sheet-like, while the remaining connecting electrodes 22 are tubular or annular sheets, and are spaced apart and insulated from each other on the body 121. Alternatively, all the connecting electrodes 22 can be tubular or annular sheets, and are spaced apart and insulated from each other on the body 121.

[0074] Specifically, the outer periphery of the connecting electrode 22 can be circular. That is, the connecting electrode 22 can be cylindrical, disc-shaped, annular, tubular, etc. Of course, it can also be polygonal, elliptical, irregular, or other shapes.

[0075] The connection electrode 22 and the electrode lead 23 will be further described below through one specific embodiment:

[0076] like Figure 1 and Figure 3 As shown, in this embodiment, the connecting electrode 22 includes a first connecting electrode 221 and a second connecting electrode 222, and the electrode lead 23 includes a first electrode lead 231 and a second electrode lead 232. The first connecting electrode 221 is circular. The second connecting electrode 222 is annular and concentrically fitted around the first connecting electrode 221. Both are coaxially arranged on the side of the body 121 opposite to the housing 11. One end of the first electrode lead 231 and one end of the second electrode lead 232 are electrically connected to the heating element 21, respectively. The other end of the first electrode lead 231 passes through the atomization channel 200 through the base 12 and is electrically connected to the first connecting electrode 221; the other end of the second connecting electrode 222 passes through the atomization channel 200 through the base 12 and is electrically connected to the second connecting electrode 222.

[0077] By passing the first electrode lead 231 and the second electrode lead 232 through the base 12, the electrode lead 23 can also be limited, thus preventing the two electrode leads 23 from contacting each other and causing a short circuit.

[0078] like Figure 2As shown, in some embodiments, the liquid guiding assembly 30 may further include an insulating fixing member 34 disposed within the liquid guiding member 31 for positioning the electrode leads 23, thereby further preventing short circuits between the electrode leads 23.

[0079] Specifically, the fixing member 34 can be positioned within the liquid guiding member 31 between the second liquid storage member 33 and the base 12, and its central part can be defined by a through channel along the axial direction to allow the air inlet 1211 on the base 12 to communicate with the atomizing channel 200, thereby enabling gas flow. The electrode leads 23 can be interleaved and passed through the fixing member 34 at intervals.

[0080] It should be understood that the fastener 34 can be installed in the liquid guiding component 31 by means of interference fit, snap connection, threaded connection, integral molding, etc., and no specific limitation is made here.

[0081] In some embodiments, the heating element 21 can be configured as a sheet-like structure of various shapes, which can be attached to the inner wall surface of the second liquid storage component 33, or it can be disposed within the atomizing channel 200 by adding a liquid guiding structure. It can also be configured as a block-shaped, needle-shaped, cylindrical, spiral, or other shapes. The various structures can be formed by winding a linear filament structure, or by bending or folding a mesh structure, etc. No specific limitation is made here.

[0082] This application also constructs an atomizer (not shown in the figure), which may include the atomizing core 1 of any of the foregoing embodiments. The atomizer may define a liquid storage chamber, which stores atomizing liquid inside. The liquid storage chamber may be connected to the liquid inlet 111 of the atomizing core 1 so that the liquid flows to the atomizing assembly 20 for heating and atomization during the user's inhalation.

[0083] This application also provides an electronic atomizing device (not shown in the figure), which may include the atomizing core 1 in any of the foregoing embodiments. The electronic atomizing device may define a liquid storage chamber, which stores atomizing liquid inside. The liquid storage chamber may be connected to the liquid inlet 111 of the atomizing core 1 so that the liquid flows to the atomizing assembly 20 for heating and atomization during the user's inhalation.

[0084] In some embodiments, the electronic atomizing device may further include a power supply unit (not shown in the figure), which can be electrically connected to the atomizing component 20 of the atomizing core 1 to supply power to the atomizing core 1.

[0085] It is important to understand that the atomization method of this electronic atomizing device is not limited.
