The base is matched with the top cover. The atomization assembly comprises a liquid guide and a heating element. The liquid guide is limited between the top cover and the base, and the liquid guide has an atomization surface facing the base. The heating element is attached to the atomization surface and abuts against the base in a limited manner. The surface of the base facing the heating element is an abutting surface, and the abutting surface and the surface of the heating element are configured to abut in a non-planar manner.

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

[0002] Atomizing devices typically consist of a housing, an atomizing component, and a power source. The housing stores the aerosol-generating matrix, the atomizing component heats and atomizes the aerosol-generating matrix to form an inhalable mist, and the power source supplies power to the atomizing component.

[0003] In related technologies, the heating element in the atomizing device needs to be rolled into a semi-cylindrical shape, and then a cotton sheet is wrapped around its surface. The cotton sheet is also rolled into a cylindrical shape and finally inserted into a cylindrical fixing base. In this case, the heating element is only wrapped on the outside with cotton sheet, and there is no fixing structure on the inside. The heating element is prone to deformation, and the assembly quality between the heating element and the cotton sheet is unstable, which leads to problems such as burnt smell or leakage in the atomizing device. Summary of the Invention

[0010] In one embodiment, the heating element and the atomizing surface are configured to fit together in an arcuate manner.

[0011] In one embodiment, the base includes a base body and a flexible seat, the flexible seat being assembled on the base body, the liquid guiding element and the heating element being located between the top cover and the flexible seat, and the side surface of the flexible seat facing the heating element being configured as the abutment surface.

[0012] In one embodiment, the seat body is provided with an air intake channel communicating with the atmosphere, and the flexible seat is provided with an atomizing cavity that penetrates at least the abutment surface and communicates with the air intake channel, the atomizing cavity communicating with the heating element.

[0013] In one embodiment, the base has an atomizing chamber that communicates with the heating element, and the top cover has a liquid guiding channel and a first air passage. The liquid guiding channel communicates with the liquid guiding element, and the first air passage communicates with the atomizing chamber.

[0014] In one embodiment, the liquid guiding component further includes a liquid absorbing surface, which is disposed opposite to the atomizing surface and blocks the outlet of the liquid guiding channel.

[0015] In one embodiment, the top cover has an inner top surface facing the liquid absorption surface, the liquid guiding channel penetrates the inner top surface, and a liquid receiving groove recessed away from the liquid absorption surface is formed on the inner top surface.

[0016] In one embodiment, the top cover is further provided with a second air passage, one end of which is connected to the atomizing chamber and the other end is configured to be connected to a liquid storage chamber for supplying liquid to the liquid guiding channel.

[0017] In one embodiment, a first space is also formed inside the top cover, and both the second air passage and the first air passage are connected to the atomizing chamber through the first space.

[0018] In one embodiment, the top cover includes an inner cover and an outer cover, the inner cover is assembled and connected to the base, and the outer cover is sleeved on the outer periphery of the inner cover; the liquid guiding element and the heating element are confined between the inner cover and the base, the liquid guiding channel, the first air channel and the second air channel all pass through the inner cover and the outer cover simultaneously, and the inner cover forms the first space.

[0019] In one embodiment, the inner cover is provided with a liquid storage channel communicating with the first space, and the outer cover is provided with a vent for communicating with the liquid storage chamber. The vent communicates with the liquid storage channel and together form the second air passage.

[0020] The liquid storage channel is configured to retain liquid.

[0021] In one embodiment, the inner cover has a first peripheral wall surrounding the atomizing component, and a plurality of liquid storage grooves are formed on the first peripheral wall opposite to the recess of the outer cover. The plurality of liquid storage grooves are arranged in a staggered manner and connected in sequence. All the liquid storage grooves and the outer cover together form the liquid storage channel.

Simultaneously, the base's non-planar contact with the heating element results in a larger contact area, more even force distribution on the heating element, and more stable contact between the heating element and the atomizing surface. Furthermore, the non-planar contact between the base and the heating element leads to a larger heating area and better atomization. Attached Figure Description

[0053] In order to solve the problem mentioned in the background art that the unstable assembly quality of the heating element and the cotton pad leads to problems such as burnt smell or leakage in the atomizing device, this application provides an atomizing structure, an atomizer, and an electronic atomizing device.

[0054] Please refer to Figures 1 to 3 This is a schematic diagram of the structure of an electronic atomizing device 1000 provided in some embodiments of this application. The electronic atomizing device 1000 includes an atomizer 100 and a power supply component 300, which provides electrical energy to the atomizer 100.

[0055] The power supply assembly 300 may include a housing 301 and a battery housed within the housing 301, in which case the power supply assembly 300 supplies power to the atomizer 100 via its own battery. The power supply assembly 300 may also supply power to the heating element 132 by connecting to mains power. The power supply assembly 300 is a common component in the art, and its specific structure is defined herein.

[0056] The atomizer 100 is a device capable of atomizing an aerosol-generating matrix to form an aerosol when powered on. The aerosol-generating matrix includes aerosol-generating matrices capable of being atomized to produce aerosols. Specifically, the aerosol-generating matrix includes, but is not limited to, e-liquids, liquid medications, and other aerosol-generating matrices.

[0057] Further, the atomizer 100 includes a housing 20 and an atomizing structure 10, with the housing 20 mating with the atomizing structure 10. Specifically, the atomizing structure 10 includes an atomizing component 13, and the housing 20 has a liquid storage chamber 201 for storing the aerosol generation matrix. The liquid storage chamber 201 is used to supply the aerosol generation matrix to the atomizing component 13 in the atomizing structure 10 and to atomize the aerosol generation matrix when energized. Specifically, the liquid storage chamber 201 is in communication with a liquid guide 131 in the atomizing component 13 to deliver the aerosol generation matrix to the liquid guide 131.

[0058] Furthermore, the housing 20 may also include a suction chamber 202, which is connected to the interior of the atomizing structure 10 and is used to guide the aerosol formed by the atomizing component 13 to the gas-using side. In practical applications, the housing 20 can serve as a suction nozzle for user use. When the gas-using side is subjected to suction force through the suction chamber 202, the aerosol-generating matrix in the liquid storage chamber 201 can enter the atomizing structure 10 and be absorbed and atomized by the atomizing component 13.

[0059] The atomizing structure 10 involved in the atomizer 100 in the embodiments of this application will be described below.

[0060] Please refer to Figure 2 , Figure 3 and Figure 4 This application provides several embodiments of an atomizing structure 10, which includes a top cover 11, a base 12, and an atomizing component 13. The top cover 11 is mated with the base 12. The atomizing component 13 includes a liquid guiding element 131 and a heating element 132. The liquid guiding element 131 is located between the top cover 11 and the base 12 and has an atomizing surface 131a facing the base 12. The heating element 132 is attached to the atomizing surface 131a and abuts against the base 12. The surface of the base 12 facing the heating element 132 is abutting surface 12a, and the abutting surface 12a and the heating element 132 are configured to a non-planar abutment.

[0061] The liquid-guiding component 131 refers to a component capable of absorbing the aerosol-generating matrix and allowing the aerosol-generating matrix to diffuse within itself. Specifically, the liquid-guiding component 131 may have micropores inside, allowing the aerosol-generating matrix to flow between the channels formed by the micropores under the action of capillary force, thereby diffusing within the liquid-guiding component 131. The liquid-guiding component 131 may be in the form of liquid-guiding cotton, liquid-guiding porous ceramic, etc., without limitation. The heating element 132 refers to a component that can generate heat when energized. Specifically, it may be a resistance heating element 132, an infrared heating element 132, etc. The heating element 132 may be in the form of a heating plate, a heating mesh, etc.

[0062] The aerosol generation matrix in the liquid storage chamber 201 is diffused to its atomizing surface 131a through the liquid guiding component 131 and is heated and atomized by the heating component 132. The aerosol generated by atomization is absorbed by the gas side through the suction chamber 202.

[0063] The atomizing surface 131a of the liquid guiding component 131 refers to the surface that is in contact with the heating component 132. The atomizing surface 131a is in contact with the heating component 132, and the heating component 132 can heat the aerosol generation matrix that penetrates into the atomizing surface 131a to generate aerosol.

[0064] Non-planar contact indicates that the first surface of the heating element 132 in contact with the contact surface 12a is non-planar, the contact surface 12a is non-planar, and the shapes of the two match. The contact surface 12a being non-planar means that the shape of any cross-section of the contact surface 12a parallel to the first direction X is not linear. Specifically, the cross-sectional shape of the contact surface 12a can be curved (corresponding to a curved surface), arc-shaped (corresponding to an arc surface), stepped (corresponding to a stepped surface), etc.

[0065] When the contact surface 12a and the heating element 132 are not in planar contact, the contact area between the contact surface 12a and the heating element 132 is larger, the heating element 132 is less likely to deform under the support of the contact surface 12a, and the fit with the liquid guiding element 131 is more stable.

[0066] Understandably, the entire contact surface 12a can be in contact with the heating element 132, or only a portion of the contact surface 12a can be in contact with the heating element 132, as long as the contact portion is not planar. When a portion of the contact surface 12a is in contact with the heating element 132, the remaining area of ​​the contact surface 12a can abut against the liquid guiding element 131 (e.g., Figure 3 and Figure 4 (Example shown).

[0067] In the aforementioned atomizing structure 10, when the top cover 11 is engaged with the base 12, the liquid guiding component 131 and the heating component 132 are positioned between the top cover 11 and the base 12. At this time, the base 12 and the top cover 11 limit the heating component 132 and the liquid guiding component 131, preventing relative displacement between them and helping to avoid deformation of the heating component 132 and its separation from the liquid guiding component 131. Simultaneously, the base 12 abuts against the heating component 132 via its non-planar contact surface 12a, resulting in a larger contact area between the heating component 132 and the base 12, more even force distribution on the heating component 132, and more stable contact between the heating component 132 and the atomizing surface 131a. Furthermore, the non-planar contact between the contact surface 12a and the heating component 132 results in a larger heating area for the heating component 132, leading to better atomization. The liquid guiding component 131 can be positioned and abutted between the top cover 11 and the base 12. Alternatively, the liquid guiding component 131 may be positioned between the top cover 11 and the base 12, but only abutting against the top cover 11, with the other side abutting against the base via the heating element 132; the specific placement is not limited. Preferably, the liquid guiding component 131 may be positioned between the top cover 11 and the base 12. In this case, when the heating element 132 covers the entire atomizing surface 131a, the portion of the liquid guiding component 131 not in contact with the heating element 132 abuts against the base 12, making the structure of the liquid guiding component 131 more stable.

[0068] For specific embodiments, please refer to Figure 3 and Figure 4 The abutment surface 12a and the heating element 132 are configured to abut against each other using an arc surface. The arc surface abutment includes circular arc surface abutment and elliptical arc surface abutment, and is not specifically limited. Specifically, the abutment surface 12a can be an arc surface convex towards the heating element 132, or the surface of the heating element 132 facing the abutment surface 12a can be an arc surface convex towards the abutment surface 12a. When the abutment surface is an arc surface, the abutment surface is simpler to process and easier to implement.

[0069] In some specific embodiments, refer to... Figure 3 and Figure 4 The heating element 132 and the atomizing surface 131a are configured to fit together in an arc shape. That is, the second surface of the heating element 132 that contacts the atomizing surface 131a is an arc surface, and the atomizing surface 131a is an arc surface that fits the second surface. Both the first and second surfaces are arc surfaces; specifically, the first and second surfaces can be parallel arcs. In this case, the heating element 132 can be obtained by bending a straight heating element 132 to a certain degree of curvature, making the forming of the heating element 132 more convenient and reducing costs.

[0070] When the heating element 132 is in contact with the arc surface of the atomizing surface 131a, the contact area between the heating element 132 and the atomizing surface 131a is large, resulting in more aerosols generated per unit time and higher atomization efficiency of the atomizing structure 10. At the same time, the arc surface provides better envelopment, and the connection between the heating element 132 and the atomizing surface 131a is more stable.

[0071] In some embodiments, continue to refer to Figure 3 and Figure 4 The base 12 includes a base body 121 and a flexible base 122. The flexible base 122 is mounted on the base body 121. The liquid guiding component 131 and the heating component 132 are located between the top cover 11 and the flexible base 122. The surface of the flexible base 122 facing the heating component 132 is constructed as an abutment surface 12a.

[0072] The flexible seat 122 can be formed from a flexible material, such as a silicone seat, a rubber seat, or a soft plastic seat. The flexible seat 122 can also be an airbag seat, possessing flexibility through the compressibility of the gas filling it.

[0073] The flexible seat 122 is used to construct the abutment surface 12a, and the base 12 and the heating element 132 are flexibly abutted together. The flexible seat 122 can be used to compensate for the dimensional tolerances of parts such as the heating element 132 and the liquid guiding element 131, and the heating element 132 and the liquid guiding element 131 are more tightly fixed.

[0074] In an optional embodiment, the seat body 121 and the flexible seat 122 are integrally connected. That is, the seat body 121 and the flexible seat 122 are integrally formed. In other embodiments, the seat body 121 and the flexible seat 122 can be separately configured and assembled into one unit. For example, the flexible seat 122 and the seat body 121 are assembled together by a snap-fit ​​connection. The specific connection method between the flexible seat 122 and the seat body 121 is not limited in this application.

[0075] In some embodiments, please refer to Figure 4 , Figure 7 and Figure 8 The seat body 121 has an air intake channel 12c that communicates with the atmosphere, and the flexible seat 122 has an atomizing chamber 12b that penetrates at least the abutment surface 12a and communicates with the air intake channel 12c. The atomizing chamber 12b is connected to the heating element 132.

[0076] The air intake passage 12c can be directly or indirectly connected to the atmosphere. Direct connection means the air intake passage 12c passes through the wall of the base body 121 facing the atmospheric environment. Indirect connection means the air intake passage 12c connects to the atmosphere through an intermediate component. Figure 2 In the embodiment shown, a vent 302 is provided on the housing 301 of the power supply component 300. The air intake channel 12c connects to the inside of the housing 301, and the vent 302 connects the inside and outside of the housing 301. Thus, air intake is achieved through the inside of the housing 301 and the vent 302 to communicate with the atmosphere.

[0077] The atomizing chamber 12b penetrates the abutment surface 12a, meaning that the atomizing chamber 12b opens at least toward the heating element 132, allowing the aerosol formed by atomization by the heating element 132 to enter the atomizing chamber 12b.

[0078] Understandably, the atomizing chamber 12b can be connected to the suction chamber 202 to facilitate the extraction of aerosol from the atomizing chamber 12b when suction is provided on the gas-consuming side. The air inlet channel 12c is connected to the atomizing chamber 12b. When suction is provided on the gas-consuming side, atmospheric air enters the atomizing chamber 12b through the air inlet channel 12c, which can drive the aerosol in the atomizing chamber 12b to flow towards the suction chamber 202, and finally flow to the gas-consuming side.

[0079] The atomizing chamber 12b provides space to contain aerosols. When the user side is drawing in air, more air can enter the air intake channel 12c, thereby carrying away the aerosols, making it easier for the user to inhale the aerosols.

[0080] Further in the embodiments, please refer to Figure 7 and Figure 13 The base body 121 has multiple spaced air inlets 12c1, each of which connects to the atomization chamber 12b and the atmosphere. All the air inlets 12c1 together form an air intake channel 12c. The air intake channel 12c is formed by multiple air inlets 12c1, and the solid structure between the air inlets 12c1 helps to prevent or slow down the entry of aerosol matrix that drips from the atomization surface 131a and cannot be atomized in time into the air intake channel 12c.

[0081] Of course, in other embodiments, the atomizing chamber 12b may not be provided on the base 12. For example, the aerosol can be contained by the heating element 132, such as the mesh of the heating net itself. However, the space for containing the aerosol is small, and it is not easy for the user to inhale.

[0082] In some embodiments, please refer to Figure 12 The seat body 121 has a second space 121c. The second space 121c is configured to communicate with the suction chamber 202, and the atomizing chamber 12b is communicated with the second space 121c to realize the discharge of aerosol in the atomizing chamber 12b.

[0083] Specifically, please refer to Figure 12 The flexible seat 122 has a groove 12b1 recessed into the abutment surface 12a facing the seat body 121, and a through hole 12b2 penetrating the bottom of the groove 12b1 and the flexible seat 122. The through hole 12b2 is opposite to and communicates with the air intake channel 12c. The groove 12b1 extends through the flexible seat 122 in its own extending direction. The groove 12b1 and the through hole 12b2 form an atomizing chamber 12b. At this time, both sides of the groove 12b1 in the extending direction are connected to the outside of the flexible seat 122 and communicate with the second space 121c, realizing the communication between the atomizing chamber 12b and the suction chamber 202.

[0084] In other embodiments, the groove 12b1 may not penetrate the flexible seat 122 in its extending direction, and a space connecting the through hole 12b2 and the second space 121c may be formed between the seat body 121 and the flexible seat 122. The specific method is not limited, as long as the atomizing cavity 12b and the second space 121c can be connected.

[0085] Further in the embodiments, refer to Figure 12 The bottom of the groove 12b1 has a recessed storage groove 12b3 that is recessed away from the heating element 132. Specifically, the storage groove 12b3 may include multiple interconnected grooves. In this case, the storage groove 12b3 can accommodate the aerosol generation matrix that falls from the atomizing surface 131a, reducing the leakage of the aerosol generation matrix.

[0086] In some embodiments, reference is made together with Figure 4 and Figure 13 The heating element 132 includes two electrode terminals 131a, which are arranged on the same side of the heating element 132. The base body 121 has a wire hole 121b for passing through the electrode terminals 131a.

[0087] Electrode terminal 131a is connected to power supply assembly 300 via a wire to obtain electrical energy from power supply assembly 300 to heat heating element 132. The wire passes through wire hole 121b on base body 121, through which heating element 132 can be positioned. Figure 4 In the embodiment shown, electrode terminals 131a are arranged on the same side of the heating element 132 in the second direction that intersects the first direction.

[0088] At this time, the wire can be routed from one side of the heating element 132, making the wire routing simpler and more convenient for assembling the atomizing structure 10. Correspondingly, the wire hole 121b can be compactly arranged on the base body 121.

[0089] Understandably, the wire through hole 121b may include two, each wire through hole 121b being used to pass through an electrode terminal 131a.

[0090] In some embodiments, please refer to Figure 5 , Figure 7 and Figure 8 The base 12 has an atomizing chamber 12b that communicates with the heating element 132. The top cover 11 has a liquid guiding channel 11a and a first air channel 11b. The liquid guiding channel 11a communicates with the liquid guiding element 131, and the first air channel 11b communicates with the atomizing chamber 12b.

[0091] The liquid guiding channel 11a is used to transport the aerosol generation matrix to the liquid guiding component 131, and the first air channel 11b is used to output the aerosol generated by the heating element 132 in the atomization chamber 12b. It is configured to communicate with the suction chamber 202.

[0092] The aerosol generating matrix flows through the liquid guiding channel 11a to the liquid guiding component 131. After being absorbed by the liquid guiding component 131, it is atomized by the heating element 132 through the atomizing surface 131a of the liquid guiding component 131 to form an aerosol. The aerosol then flows to the gas-using side through the atomizing chamber 12b, the first air passage 11b, and the suction chamber 202. At this time, both the liquid guiding channel 11a and the first air passage 11b are constructed in the top cover 11, making the arrangement of the housing 20, the power supply component 300, and the atomizer 100 in the electronic atomizing device 1000 more reasonable.

[0093] Of course, in other embodiments, the liquid channel 11a and / or the first air channel 11b may also be provided on the base 12.

[0094] In some embodiments, reference is made together with Figure 4 and Figure 7 The liquid guiding component 131 also includes a liquid absorption surface 131b, which is disposed opposite to the atomizing surface 131a and blocks the outlet of the liquid guiding channel 11a.

[0095] The liquid absorption surface 131b is sealed at the outlet of the liquid guiding channel 11a. The aerosol flowing out of the liquid guiding channel 11a is absorbed by the liquid absorption surface 131b in time and will not penetrate into the space formed inside the top cover 11 and the base 12. This can avoid adverse phenomena such as leakage of the aerosol generation matrix through the joint between the top cover 11 and the base 12.

[0096] In other embodiments, the liquid absorption surface 131b may also be arranged on one or more sides of the liquid guiding member 131 that intersect and connect with the atomizing surface 131a.

[0097] In some embodiments, reference is made together with Figure 8 and Figure 10 The top cover 11 also has an inner top surface 111a facing the liquid absorption surface 131b, and a liquid guiding channel 11a passes through the inner top surface 111a. A liquid receiving groove 111a1 is constructed on the inner top surface 111a that is recessed away from the liquid absorption surface 131b.

[0098] Specifically, the liquid receiving tank 111a1 may include multiple interconnected tanks. The liquid receiving tank 111a1 is recessed on the inner top surface 111a, facing away from the liquid absorption surface 131b, indicating that the liquid receiving tank 111a1 opens towards the liquid absorption surface 131b. When the aerosol generating matrix absorbed within the liquid guiding member 131 is saturated, the aerosol generating matrix overflowing from the liquid guiding member 131 can be temporarily stored in the liquid receiving tank 111a1, helping to prevent the overflowing aerosol generating matrix from leaking to other places.

[0099] In some embodiments, reference is made together with Figures 7 to 9 The top cover 11 is also provided with a second air passage 11c, one end of which is connected to the atomizing chamber 12b, and the other end is configured to be connected to the liquid storage chamber 201 for supplying liquid to the liquid guiding channel 11a.

[0100] The second air passage 11c is used for gas flow. The second air passage 11c connects the liquid storage chamber 201 and the atomizing chamber 12b. As can be seen from the above description, the atomizing chamber 12b is connected to the atmosphere through the air intake passage 12c. In other words, the second air passage 11c can connect the atmosphere to the liquid storage chamber 201.

[0101] The second air passage 11c connects the containment space 10a and the liquid storage chamber 201, so that the air pressure in the liquid storage chamber 201 is kept at a similar level to the atomizing chamber 12b and the atmospheric pressure, thereby allowing the liquid in the liquid storage chamber 201 to flow smoothly into the liquid guiding channel 11a and be absorbed by the liquid guiding component 131.

[0102] In some embodiments, referring to 8, a first space 11d is also formed inside the top cover 11, and the second air passage 11c and the first air passage 11b are both connected to the atomizing chamber 12b via the first space 11d. Specifically, the first space 11d can be connected to the second space 121c to connect to the atomizing chamber 12b. In this case, the first space 11d enables the connection between the second air passage 11c and the first air passage 11b and the atomizing chamber 12b.

[0103] For specific implementation examples, please refer to Figure 4 The top cover 11 includes an inner cover 111 and an outer cover 112. The inner cover 111 is assembled and connected to the base 12, and the outer cover 112 is fitted around the outer periphery of the inner cover 111. The liquid guiding component 131 and the heating component 132 are confined between the inner cover 111 and the base 12. The liquid guiding channel 11a, the first air channel 11b, and the second air channel 11c all pass through the inner cover 111 and the outer cover 112 simultaneously, and the inner cover forms a first space 11d.

[0104] Understandably, when the base 12 includes the aforementioned base body 121 and flexible base 122, the inner cover 111 is assembled with the base body 121. The first space 11d can communicate with the atomizing chamber 12b via the second space 121c formed by the base body 121.

[0105] The outer cover 112 being fitted around the outer periphery of the inner cover 111 means that the outer cover 112 covers the outer periphery of the inner cover 111 except for the side facing the base 12. Since the liquid guiding channel 11a, the first air channel 11b and the second air channel 11c are all connected to the outside of the receiving space 10a, they all penetrate both the inner cover 111 and the outer cover 112.

[0106] At this time, the top cover 11 is composed of an inner cover 111 and an outer cover 112. The outer cover 112 can cover the assembly connection between the inner cover 111 and the base 12, making it more aesthetically pleasing.

[0107] To prevent the aerosol generation matrix in the liquid storage chamber 201 from entering the atomization chamber 12b through the second air passage 11c, the content of the aerosol generation matrix entering the second air passage 11c can be reduced by reasonably designing the flow area of ​​the second air passage 11c. Furthermore, a permeable membrane for gas passage can be set in the second air passage 11c. Furthermore, the second air passage 11c can be designed as a structure that can store the aerosol generation matrix and allow air to pass through. The specific design is not limited.

[0108] In some embodiments, please refer to Figure 4 , Figure 7 and Figure 8 The inner cover 111 has a liquid storage channel 11c3 that communicates with the first space 11d, and the outer cover has a vent 11c1 that communicates with the liquid storage chamber 201. The vent 11c1 communicates with the liquid storage channel 11c3 and together form a second air passage 11c. The liquid storage channel 11c3 is configured to retain liquid.

[0109] The second air passage 11c includes a vent 11c1 and a liquid storage channel 11c3 connected in sequence. The vent 11c1 and the inlet of the liquid channel 11a can be located on the same side of the outer cover 112. Understandably, the vent 11c1 has a small aperture to reduce the aerosol generation matrix entering the second air passage 11c from the liquid storage chamber 201.

[0110] The liquid storage channel 11c3 is configured to retain liquid, allowing a small amount of aerosol-generating matrix entering the second air passage 11c from the liquid storage chamber 201 to be retained within itself, preventing the aerosol-generating matrix from entering the first space 11d and causing oil leakage. The liquid storage channel 11c3 may take the form of, but is not limited to, a liquid storage blind hole and a connecting channel. The opening of the liquid storage blind hole connects to the ventilation hole 11c1 and the connecting channel. The connecting channel connects to the first space 11d. The aerosol-generating matrix entering from the ventilation hole 11c1 is stored in the liquid storage blind hole by gravity, while the gas enters the first space 11d through the connecting channel to maintain a consistent pressure difference between the liquid storage chamber 201 and the first space 11d.

[0111] At this time, the second air passage 11c stores a small amount of aerosol generation matrix through the liquid storage channel 11c3, preventing the aerosol generation matrix from entering the first space 11d and causing oil leakage.

[0112] For specific implementation examples, please refer to Figure 4 Please refer to the above. Figure 5 , Figure 7 and Figure 8The inner cover 111 has a first peripheral wall 111b surrounding the atomizing component 13. The first peripheral wall 111b has a liquid storage tank 111c recessed away from the outer cover 112. Multiple liquid storage tanks 111c are arranged in a staggered manner and connected in sequence. All the liquid storage tanks 111c and the outer cover 112 together form a liquid storage channel 11c3. The first space 11d penetrates the first peripheral wall 111b and is connected to the liquid storage channel 11c3.

[0113] Multiple liquid storage tanks 111c are arranged in an alternating manner, meaning that each pair of adjacent connected liquid storage tanks 111c intersects, forming a maze-like structure. The outer cover 112 seals the opening of the liquid storage tank 111c to form a liquid storage channel 11c3. The accommodating space 10a penetrates the first peripheral wall 111b and communicates with the liquid storage channel 11c3 through the gap between the first peripheral wall 111b and the outer cover 112.

[0114] At this time, the liquid storage tank 111c is arranged in a maze shape on the first peripheral wall 111b of the inner cover 111. The liquid storage tank 111c is simple to process and easy to realize.

[0115] Further in the embodiments, reference is made to... Figure 5 and Figure 8 The second airway 11c includes a transition channel 11c2, which is located between the liquid storage channel 11c3 and the air exchange hole 11c1. The transition channel 11c2 is constructed on the inner cover 111.

[0116] In some embodiments, the outer cover 112 is a flexible component. Specifically, the outer cover 112 is made of silicone, rubber, or the like. When the outer cover 112 is flexible, it can increase the tightness of the connection between the top cover 11 and other components (such as the housing 20) and the dimensional tolerance.

[0117] In some embodiments, please refer to Figure 4 , Figure 9 and Figure 13 The base 12 and the top cover 11 are assembled and connected along the first direction X, and the atomizing component 13 is clamped between the base 12 and the top cover 11 in the first direction X.

[0118] like Figure 3 and Figure 4 In the illustrated embodiment, the first direction X corresponds to the up-down direction in the diagram. The top cover 11 and the base 12 are assembled and connected along the first direction X. The assembly method of the top cover 11 and the base 12 can be, but is not limited to, snap-fitting along the first direction X or fastening along the first direction X (such as fastening via bolts, studs, pins, or other components extending along the first direction X). Furthermore, the top cover 11 and the base 12 can be detachably assembled and connected along the first direction X, facilitating the replacement of internal parts.

[0119] Understandably, when the base 12 includes a base body 121 and a flexible base 122, and the top cover 11 includes an inner cover 111 and an outer cover 112, the base body 121 and the inner cover 111 are assembled and connected along the first direction X.

[0120] exist Figure 3 and Figure 4 In the preferred embodiment shown, the top cover 11 and the base 12 are snapped together along the first direction X. Specifically, the top cover 11 is constructed with a first snap-fit ​​portion 111d protruding toward the base 12 along the first direction X, and the base 12 has a second snap-fit ​​portion 121a that mates with the first snap-fit ​​portion 111d. When the top cover 11 and the base 12 are assembled in place along the first direction X, the first snap-fit ​​portion 111d and the second snap-fit ​​portion 121a are snapped into place simultaneously, making the assembly of the base 12 and the top cover 11 more convenient.

[0121] When assembling the atomizing structure 10, the top cover 11, the liquid guiding component 131, the heating element 132, and the base 12 can be assembled sequentially along the first direction X. When the top cover 11 and the base 12 are assembled as one unit, the liquid guiding component 131 and the heating element 132 are confined between the top cover 11 and the base 12. At this time, during the assembly process, the heating element 132 and the liquid guiding component 131 do not need to be rolled into a cylindrical shape, resulting in higher assembly efficiency.

[0122] The aforementioned atomizing structure 10, atomizer 100, and electronic atomizing device 1000, through the base 12 and top cover 11, limit the heating element 132 and liquid guiding element 131, preventing relative displacement between them and helping to avoid detachment of the heating element 132 and liquid guiding element 131. Simultaneously, the base 12 abuts against the surface of the heating element 132 via its abutting surface 12a, resulting in more even force distribution on the heating element 132 and more stable contact between the heating element 132 and the atomizing surface 131a. Furthermore, during assembly, the heating element 132 and liquid guiding element 131 do not need to be rolled into a cylindrical shape, resulting in higher assembly efficiency.

[0123] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0124] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
