Description

Technical Field

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

[0002] The electronic atomizing device contains an atomizing core. The heating element of the atomizing core heats the aerosol matrix inside the atomizing device, thereby producing an aerosol for the user to inhale.

[0003] The atomizing core is assembled from multiple precision parts, including a heating element, a liquid guiding element, an insulating support, and a housing. The assembly process for this structure is complex, especially in the process of coating the liquid guiding cotton. Due to the flexibility and deformation characteristics of the cotton material, it is difficult to ensure the consistency of the liquid guiding cotton coating in actual production. Furthermore, the assembly process is relatively complex, resulting in high production costs and hindering the improvement of the atomizing core's consistency and stability.

[0004] The above statements are for the purpose of providing background information in relation to this application only and do not necessarily constitute prior art. Utility Model Content

[0005] The purpose of this application is to provide an atomizing core and an electronic atomizing device that can reduce the manufacturing cost of the atomizing core and improve its consistency and stability.

[0006] The technical solution adopted in the embodiments of this application is:

[0007] In a first aspect, an atomizing core is provided, including a bracket, a ceramic liquid guiding component, and a heating element. The bracket has a mounting hole and a liquid inlet communicating with the mounting hole. The ceramic liquid guiding component is disposed in the mounting hole. The heating element is disposed in the ceramic liquid guiding component. The bracket, the ceramic liquid guiding component, and the heating element are an integral ceramic slurry injection structure.

[0008] Optionally, along the axial direction of the mounting hole, at least one end face of the ceramic liquid guide member surrounds the hole wall to form a receiving space.

[0009] Optionally, the ceramic liquid guiding component has an airflow hole, and the heating element includes a connected heating body and pins, with the heating body embedded in the hole wall of the airflow hole and exposed on the hole wall surface of the airflow hole.

[0010] Optionally, the embedding depth of the heating element into the inner wall of the airflow hole ranges from 0.01 mm to 0.03 mm.

[0011] Optionally, at least a portion of the pins are embedded within a ceramic liquid guide.

[0012] Optionally, the ceramic liquid guide has a first end face, and the first end face and the heating body are spaced apart along the axial direction of the airflow hole; the pin includes a first segment, a middle segment and a second segment, the middle segment is connected between the first segment and the second segment, the first segment is connected to the inner side of the heating body, the second segment is located on the side of the first end face away from the heating body, and at least a portion of the middle segment is embedded in the ceramic liquid guide.

[0013] Optionally, the distance between the heating element and the first end face is in the range of 2mm to 10mm.

[0014] Optionally, the heating element is a mesh heating plate.

[0015] Optionally, there are multiple liquid inlet holes, which are arranged at intervals along the circumference of the mounting hole.

[0016] Secondly, an electronic atomizing device is provided, including the aforementioned atomizing core.

[0017] The atomizing core and electronic atomizing device provided in this application embodiment have at least one of the following technical effects: When the atomizing core is in use, the aerosol matrix flows from the liquid inlet of the bracket into the mounting hole, and then is transported to the heating element through the pores in the ceramic liquid guide component. The heating element heats the aerosol matrix to generate aerosol for the user to inhale. Furthermore, the bracket, ceramic liquid guide component, and heating element are an integrated ceramic injection structure, meaning they are manufactured using a ceramic injection process. This process simplifies the assembly steps of the bracket, ceramic liquid guide component, and heating element into a single process, which is advantageous. This design simplifies the atomizer core manufacturing process and reduces its production cost. The absence of additional connecting components between the support, ceramic liquid guide, and heating element reduces the number of parts in the atomizer core, further lowering its manufacturing cost. The ceramic liquid guide is shaped within the injection mold, and the support and heating element are positioned within the mold, allowing for precise positional control and improved atomizer core consistency. The support, ceramic liquid guide, and heating element are tightly connected, ensuring reliable connections and enhancing the structural stability of the atomizer core.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] It should also be noted that in the embodiments of this application, the same reference numerals are used to represent the same component or part. For the same part in the embodiments of this application, the reference numerals may only be used to mark one part or component as an example. It should be understood that the reference numerals are also applicable to other identical parts or components.

[0037] The electronic atomizing device contains an atomizing core. The heating element of the atomizing core heats the aerosol matrix inside the atomizing device, thereby producing an aerosol for the user to inhale.

[0038] The atomizing core is assembled from multiple precision parts, including a heating element, a liquid guiding element, an insulating support, and a housing. The assembly process for this structure is complex, especially in the process of coating the liquid guiding cotton. Due to the flexibility and deformation characteristics of the cotton material, it is difficult to ensure the consistency of the liquid guiding cotton coating in actual production. Furthermore, the assembly process is relatively complex, resulting in high production costs and hindering the improvement of the atomizing core's consistency and stability.

[0039] Based on this, this application proposes an atomizing core, in which the support, ceramic liquid guiding component, and heating element are manufactured using an integrated ceramic slurry injection process. The ceramic slurry injection process is simple to operate, which helps to reduce the assembly difficulty of the atomizing core, reduce the number of parts, and reduce the production cost of the atomizing core. The atomizing core manufactured using the ceramic slurry injection process has good consistency, and the connection between the support, ceramic liquid guiding component, and heating element has good reliability, which helps to improve the stability of the atomizing core.

[0040] For ease of explanation, the following description uses the directions of up, down, left, right, front, and back as shown in the accompanying drawings. In the drawings, the Z-axis represents the up-down direction, with the positive direction of the Z-axis indicating up and the negative direction indicating down. The Y-axis represents the left-right direction, with the positive direction of the Y-axis indicating left and the negative direction indicating right. The X-axis represents the front-back direction, with the positive direction of the X-axis indicating front and the negative direction indicating back. Of course, this directional limitation in the embodiments is merely an example to more clearly illustrate the positional relationships between the various components and does not limit the specific implementation of this application to this arrangement.

[0041] See Figures 1-3 As shown, in some embodiments, the electronic atomizing device 1 includes a housing 10, an atomizing core 20, an electronic component 30, a battery 40, and a mouthpiece 50. The housing 10 includes a first housing 11 and a second housing 12 that are interlocked. The second housing 12 is provided with a mounting bracket 71. The mounting bracket 71 and the first housing 11 enclose a first liquid storage chamber 101 for containing an aerosol matrix. The mounting bracket 71 is provided with a second liquid storage chamber 711 for containing an aerosol matrix. The mounting bracket 71 and the first housing 11 together enclose a vertically arranged receiving hole 102. The atomizing core 20 is installed in the receiving hole 102. The mounting bracket 71 is provided with a liquid inlet switch 78 for controlling the connection and disconnection of the first liquid storage chamber 101 and the second liquid storage chamber 711. When the liquid inlet switch 78 is in the open state, the aerosol matrix in the first liquid storage chamber 101 flows into the second liquid storage chamber 711, replenishing the second liquid storage chamber 711. When the liquid inlet switch 78 is in the closed state, the first liquid storage chamber 101 and the second liquid storage chamber 711 are not connected. The liquid inlet hole 212 of the atomizing core 20 is connected to the second liquid storage chamber 711. The aerosol matrix in the second liquid storage chamber 711 flows into the atomizing core 20 and is heated and atomized by the atomizing core 20 to generate an aerosol for the user to inhale.

[0042] In some embodiments, the mouthpiece 50 is mounted on the upper side of the first housing 11, and the upper end of the receiving hole 102 is provided with a first sealing member 72, which seals the mouthpiece 50 and the atomizing core 20. The first sealing member 72 has a first through hole communicating with the atomizing core 20 and the mouthpiece 50. The second housing 12 is provided with an air supply channel 121, and the lower end of the receiving hole 102 is provided with a second sealing member 73. The lower end of the atomizing core 20 is sealed to the air supply channel 121 through the second sealing member 73. The second sealing member 73 has a second through hole communicating with the air supply channel 121 and the atomizing core 20. When the user holds the mouthpiece 50 in their mouth and inhales, external gas is drawn into the air supply channel 121 to form an airflow. The airflow flows through the air supply channel 121, the atomizing core 20 and the mouthpiece 50 in sequence. As the airflow flows through the atomizing core 20, it carries away the aerosol generated by the atomizing core 20. Finally, the airflow flows out from the mouthpiece 50 for the user to inhale.

[0043] In some embodiments, the first sealing member 72 is provided with a first liquid-absorbing member 74 for absorbing condensate at the nozzle 50. A second liquid-absorbing member 75 is provided in the air supply channel 121 for absorbing condensate flowing down from the atomizing core 20. The first sealing member 72 and the second sealing member 73 may be sealing silicone rings, and the first liquid-absorbing member 74 and the second liquid-absorbing member 75 may be absorbent cotton.

[0044] In some embodiments, the electronic component 30 includes a circuit board 31, electrodes 32 disposed on the circuit board 31, and a charging interface 33. The circuit board 31 is disposed within the second housing 12 and below the second liquid-absorbing member 75. The electrodes 32 pass through the second liquid-absorbing member 75 and are electrically connected to the atomizing core 20. The battery 40 is installed within the second housing 12 and located on the right side of the atomizing core 20. The battery 40 is electrically connected to the circuit board 31. The charging interface 33 is used to charge the battery 40. The battery 40 supplies power to the atomizing core 20 through the circuit board 31 and the electrodes 32 to realize the atomization operation of the atomizing core 20. The circuitry in the circuit board 31 can be found in existing related technologies and will not be described in detail here.

[0045] In some embodiments, the bottom of the second housing 12 is also provided with a switch device 76, which can control the power supply to the atomizing core 20, and can also realize the switching control of the liquid inlet switch 78 through the linkage structure. In addition, the air supply channel 121 can also be opened and closed by toggling the switch device 76.

[0046] In some embodiments, the housing 10 further includes a front cover 13 and a rear cover 14, which are respectively disposed on the front and rear sides of the first housing 11 and the second housing 12, serving a decorative and protective function.

[0047] In some embodiments, the front cover 13 is also provided with a display screen 77 to assist in the use of the electronic atomizing device 1.

[0048] Please refer to the following: Figures 4-6 As shown, in some embodiments, the atomizing core 20 includes a support 21, a ceramic liquid guide 22, and a heating element 23; the support 21 has a mounting hole 211 and a liquid inlet hole 212 communicating with the mounting hole 211; the ceramic liquid guide 22 is disposed in the mounting hole 211; the heating element 23 is disposed in the ceramic liquid guide 22; wherein, the support 21, the ceramic liquid guide 22, and the heating element 23 are an integral ceramic grouting structure.

[0049] The support 21 can refer to the mounting base of the ceramic liquid guide 22, serving to support the ceramic liquid guide 22. The support 21 is hollow inside, and the cavity inside the support 21 is the mounting hole 211. The shape of the support 21 can be various, such as cylindrical, prismatic, etc. The support 21 is provided with a liquid inlet hole 212, which communicates with the mounting hole 211, allowing the aerosol matrix to enter the mounting hole 211 through the liquid inlet hole 212 and wet the ceramic liquid guide 22. The material of the support 21 can be various, such as metal, plastic, etc.

[0050] For example, the upper end of the bracket 21 is sealed to the first seal 72, and the lower end of the bracket 21 is sealed to the second seal 73, reducing the risk of leakage of aerosol or aerosol matrix.

[0051] For example, the support 21 is a hollow cylindrical structure, the central hole of the support 21 forms a receiving hole 102, and the through hole penetrating the side wall of the support 21 is a liquid inlet hole 212.

[0052] The ceramic liquid guiding component 22 refers to a component made of ceramic material. The ceramic liquid guiding component 22 has pores inside, through which the aerosol matrix can be transported to the heating element 23.

[0053] The heating element 23 can refer to a component capable of heating the aerosol matrix to generate aerosol; the structure of the heating element 23 is not limited, and may include, for example, a cylindrical heating plate, a thick-film heating tube, an electric heating wire, etc. The heating element 23 is electrically connected to the electrode 32, and the battery 40 supplies power to the heating element 23 to heat the aerosol matrix at the ceramic liquid-conducting component 22 to generate aerosol.

[0054] The support 21, the ceramic liquid guiding component 22, and the heating element 23 are an integrated ceramic grouting structure. It can be understood that the integrated ceramic grouting structure refers to the integrated structure obtained by the support 21, the ceramic liquid guiding component 22, and the heating element 23 using the ceramic grouting process; that is, the support 21 and the heating element 23 are fixed in the grouting mold, then ceramic material is injected into the grouting mold, and then the integrated ceramic grouting structure is obtained after high-temperature sintering.

[0055] In this embodiment of the atomizing core 20, during use, the aerosol matrix flows from the liquid inlet 212 of the support 21 into the mounting hole 211, and then is transported to the heating element 23 through the pores in the ceramic liquid guide 22. The heating element 23 heats the aerosol matrix to generate an aerosol for the user to inhale. The support 21, the ceramic liquid guide 22, and the heating element 23 are an integrated ceramic injection structure, meaning that the support 21, the ceramic liquid guide 22, and the heating element 23 are manufactured using a ceramic injection process. This ceramic injection process simplifies the assembly steps of the support 21, the ceramic liquid guide 22, and the heating element 23 into a single process, which helps to simplify the production process of the atomizing core 20 and reduce the manufacturing cost of the atomizing core 20. The cost is reduced because no other connecting parts are needed between the support 21, the ceramic liquid guide 22, and the heating element 23, which helps to reduce the number of parts in the atomizing core 20 and lower its manufacturing cost. The ceramic liquid guide 22 is shaped in the injection mold, and the support 21 and the heating element 23 are positioned in the injection mold, so the positions of the support 21, the ceramic liquid guide 22, and the heating element 23 can be accurately controlled, which helps to improve the consistency of the atomizing core 20. The support 21, the ceramic liquid guide 22, and the heating element 23 can be tightly connected together, and the connection reliability of the support 21, the ceramic liquid guide 22, and the heating element 23 is good, which helps to improve the structural stability of the atomizing core 20.

[0056] The atomizing core 20, support 21, ceramic liquid guide 22, and heating element 23 of this embodiment are manufactured using a ceramic injection process. The ceramic liquid guide 22 can fit tightly against the inner wall of the mounting hole 211, reducing the risk of aerosol matrix leakage. The atomizing core 20 of this embodiment has fewer parts and a simpler assembly process. The ceramic liquid guide 22 has better leak-proof and liquid-guiding effects compared to cotton fiber materials.

[0057] In some embodiments, along the axial direction of the mounting hole 211, at least one end face of the ceramic liquid guide 22 surrounds the hole wall of the mounting hole 211 to form a receiving space 201.

[0058] The axial direction of the mounting hole 211 can refer to the direction parallel to the axis of the mounting hole 211. Along the axial direction of the mounting hole 211, one end face of the ceramic liquid guiding component 22 is located inside the mounting hole 211, and this end face and the hole wall of the mounting hole 211 form a receiving space 201. Alternatively, both opposite end faces of the ceramic liquid guiding component 22 are located inside the mounting hole 211, and these two end faces and the hole walls at opposite ends of the mounting hole 211 respectively form two receiving spaces 201.

[0059] In some examples, the axial direction of the mounting hole 211 refers to the vertical direction, specifically the Z direction. The upper end face of the ceramic liquid guide 22 is lower than the upper end face of the bracket 21. The upper end face of the ceramic liquid guide 22 and the hole wall at the upper end of the mounting hole 211 form a receiving space 201. The first sealing member 72 can be directly inserted into the receiving space 201 to achieve a sealed connection between the first sealing member 72 and the atomizing core 20. This eliminates the need for other components for connection, which helps to reduce the number of parts in the electronic atomizing device 1, simplify the assembly process, and reduce the production cost of the electronic atomizing device 1.

[0060] In some examples, the axial direction of the mounting hole 211 refers to the vertical direction. The lower end face of the ceramic liquid guide 22 is higher than the lower end face of the bracket 21. The lower end face of the ceramic liquid guide 22 and the hole wall at the lower end of the mounting hole 211 form a receiving space 201. The second sealing member 73 can be directly inserted into the receiving space 201 to achieve a sealed connection between the second sealing member 73 and the atomizing core 20. This eliminates the need for other components for connection, which helps to reduce the number of parts in the electronic atomizing device 1, simplify the assembly process, and reduce the production cost of the electronic atomizing device 1.

[0061] In some examples, the axial direction of the mounting hole 211 refers to the vertical direction. The upper end face of the ceramic liquid guide 22 is lower than the upper end face of the bracket 21. The upper end face of the ceramic liquid guide 22 and the upper end wall of the mounting hole 211 form a receiving space 201. The lower end face of the ceramic liquid guide 22 is higher than the lower end face of the bracket 21. The lower end face of the ceramic liquid guide 22 and the lower end wall of the mounting hole 211 form a receiving space 201. The height of the liquid guide is less than the height of the bracket 21, which helps to reduce the number of parts in the electronic atomizing device 1, simplify the assembly process, and reduce the production cost of the electronic atomizing device 1.

[0062] Please refer to the following: Figure 7 As shown, in some embodiments, the ceramic liquid guide 22 has an airflow hole 221, and the heating element 23 includes a heating body 231 and a pin 232 connected to each other. The heating body 231 is embedded in the hole wall of the airflow hole 221 and exposed on the hole wall surface of the airflow hole 221.

[0063] The ceramic liquid guiding component 22 has a hollow cylindrical structure. The central hole of the ceramic liquid guiding component 22 forms an airflow hole 221. The ceramic liquid guiding component 22 is vertically arranged, and the airflow hole 221 runs through the ceramic liquid guiding component 22 from top to bottom. The airflow hole 221 can be coaxially arranged with the mounting hole 211. The axial direction of the airflow hole 221 (see Z direction for details) is parallel to the axial direction of the mounting hole 211. The airflow hole 221 is used to connect the air supply channel 121 and the nozzle 50. The airflow passes through the air supply channel 121 and the airflow hole 221 and finally flows out from the nozzle 50. During the process of the airflow passing through the airflow hole 221, it can carry away the aerosol generated by the heating body 231 for the user to inhale.

[0064] The heating element 231 refers to the main part of the heating element 23 used for heating, and the pins 232 refer to the components used for electrically connecting to the electrodes 32 and supplying power to the heating element 231. The electrodes 32 include a positive electrode 32 and a negative electrode 32. There can be two pins 232, which are electrically connected to the positive electrode 32 and the negative electrode 32 respectively, thereby connecting the heating circuit and realizing the heating of the heating element 23. The structure of the heating element 231 can be various, such as a bolt-shaped heating wire or a mesh-shaped heating plate. The pins 232 and the heating element 231 can be connected by welding or integral molding.

[0065] The heating element 231 can be distributed circumferentially along the airflow hole 221 to form an arc-shaped or ring-shaped structure.

[0066] Taking the heating element 231 as an example of an arc-shaped heating plate structure, the heating element 231 has an inner side and an outer side. The inner side is exposed on the wall surface of the airflow hole 221, and the outer side is located inside the ceramic liquid guiding component 22. The inner side is exposed on the wall surface of the airflow hole 221. The inner side and the wall surface of the airflow hole 221 are on the same arc surface, or the inner side protrudes from the wall surface of the airflow hole 221.

[0067] By adopting the technical solution of this embodiment, the heating body 231 is exposed on the hole wall of the airflow hole 221. The exposed surface of the heating body 231 heats the aerosol generated by the aerosol matrix. The aerosol can be directly carried away by the airflow in the airflow hole 221 without diffusion through the pores of the ceramic liquid guide 22, which can shorten the atomization response time and improve the atomization efficiency of the atomizing core 20.

[0068] In some embodiments, the embedding depth of the heating element 231 into the inner wall of the airflow hole 221 ranges from 0.01 mm to 0.03 mm.

[0069] It is understandable that the embedding depth of the heating element 231 into the inner wall of the airflow hole 221 is H, where 0.01mm≤H≤0.03mm.

[0070] Taking the heating element 231 as an example of an arc-shaped heating plate structure, H can be the distance between the wall surface of the airflow hole 221 and the outer surface of the heating element 231.

[0071] The value of H is 0.01mm, 0.03mm, or any number between 0.01mm and 0.03mm. For example, the value of H can be, but is not limited to, 0.01mm, 0.015mm, 0.02mm, 0.025mm, or 0.03mm.

[0072] In some cases, the thickness of the heating element 231 (the distance between the inner and outer surfaces of the heating element 231) ranges from 0.05mm to 0.15mm. With a design where H ≥ 0.01mm, the heating element 231 is embedded to a certain depth in the ceramic liquid guide 22, resulting in good connection reliability between the heating element 231 and the ceramic liquid guide 22, thus improving the structural stability of the atomizing core 20. With a design where H ≤ 0.03mm, the heating element 231 can protrude a certain height from the wall of the airflow hole 221, resulting in a large area of ​​the heating element 231 exposed within the airflow hole 221. This allows the aerosol matrix to be directly vaporized on the exposed surface of the heating element 231, resulting in good heating effect of the heating element 231 on the aerosol matrix and improving the atomization efficiency of the atomizing core 20.

[0073] In some embodiments, at least a portion of pin 232 is embedded within ceramic liquid guide 22.

[0074] While the heating element 231 is embedded in the ceramic liquid guide 22, part or all of the pins 232 are also embedded in the ceramic liquid guide 22. The heating element 23 is mostly embedded in the ceramic liquid guide 22. The connection between the heating element 23 and the ceramic liquid guide 22 is reliable, which helps to improve the structural stability of the atomizing core 20. In addition, the pins 232 are embedded in the ceramic liquid guide 22, which ensures good fixation reliability of the pins 232, reduces the risk of the pins 232 loosening and falling off the heating element 231, and the pins 232 also have good anti-pull force.

[0075] In some embodiments, the ceramic liquid guide 22 has a first end face 222, and the first end face 222 and the heating body 231 are spaced apart along the axial direction of the airflow hole 221; the pin 232 includes a first segment 2321, a middle segment 2322 and a second segment 2323, the middle segment 2322 is connected between the first segment 2321 and the second segment 2323, the first segment 2321 is connected to the inner side of the heating body 231, the second segment 2323 is located on the side of the first end face 222 away from the heating body 231, and at least a portion of the middle segment 2322 is embedded in the ceramic liquid guide 22.

[0076] The first end face 222 can be the end face of the ceramic liquid guide 22 through which the pin 232 protrudes. The bracket 21 is sleeved on the ceramic liquid guide 22, and the ceramic liquid guide 22 and the bracket 21 are coaxially arranged. The pin 232 is led out from the lower end face of the ceramic liquid guide 22, which is the first end face 222. The heating body 231 is located on the lower end face of the ceramic liquid guide 22. The pin 232 includes a first segment 2321, a middle segment 2322, and a second segment 2323 arranged from top to bottom. The second segment 2323 is located below the first end face 222, while the first segment 2321 and the middle segment 2322 are located above the first end face 222. The first segment 2321 is located above the middle segment 2322 and is connected to the inner side of the heating body 231. The second segment 2323 is located outside the ceramic liquid guide 22 for easy connection with the electrode 32. The intermediate section 2322 is located between the heating element 231 and the first end face 222. A portion of the intermediate section 2322 is embedded in the ceramic liquid guide 22, while the other portion is exposed in the airflow hole 221. Alternatively, the intermediate section 2322 may be completely embedded in the ceramic liquid guide 22. By embedding the portion of the pin 232 between the first end face 222 and the heating element 231 into the ceramic liquid guide 22, this structure is simple and easy to manufacture.

[0077] The intermediate section 2322 includes a straight sub-segment and a curved sub-segment. The straight sub-segment is connected between the curved sub-segment and the second section 2323, and the curved sub-segment is connected between the straight sub-segment and the first section 2321. The curved sub-segment bends from the first section 2321 toward the wall of the airflow hole 221 so that parts of the straight sub-segment and the curved sub-segment are embedded in the ceramic liquid guide 22 to fix the pin 232.

[0078] In some embodiments, the distance between the heating element 231 and the first end face 222 ranges from 2mm to 10mm.

[0079] It is understandable that the distance between the heating element 231 and the first end face 222 is L, where 2mm≤L≤10mm.

[0080] L can refer to the distance between the first end face 222 and the lower end face of the heating body 231.

[0081] The value of L is 2mm, 10mm, or any number between 2mm and 10mm. For example, the value of H can be, but is not limited to, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, or 10mm.

[0082] With an L≥2mm design, the heating element 231 and the first end face 222 can provide sufficient height for the embedding of the middle section 2322, so that the pin 232 can be stably fixed in the ceramic liquid guide 22. With an L≤10mm design, the height of the middle section 2322 is reasonably set, reducing the risk of displacement of the heating element 23 during the ceramic injection molding process due to the excessive length of the middle section 2322, which helps to reduce the manufacturing difficulty of the atomizing core 20.

[0083] In some embodiments, the heating element 231 is a mesh heating sheet.

[0084] The heating element 231 has a sheet-like structure and is arc-shaped, which is adapted to the shape of the airflow hole 221 so as to be stably embedded in the ceramic liquid guide 22. The heating element 231 is grid-like and has a hollow structure. The hollow structure can increase the exposed area of ​​the heating element 231, improve the vaporization effect of the aerosol matrix, and improve the atomization effect of the atomizing core 20.

[0085] In some embodiments, there are multiple liquid inlet holes 212, and the multiple liquid inlet holes 212 are arranged at intervals along the circumferential direction of the mounting hole 211.

[0086] Multiple liquid inlet holes 212 are arranged in a ring array around the axis of the support 21.

[0087] Multiple liquid inlet holes 212 are distributed circumferentially along the mounting hole 211. The aerosol matrix can enter the mounting hole 211 from the periphery of the bracket 21 and wet the ceramic liquid guide 22 from the periphery of the ceramic liquid guide 22. The aerosol matrix is ​​evenly distributed in the ceramic liquid guide 22, which is beneficial to improving the atomization effect of the atomizing core 20.

[0089] The electronic atomizing device 1 of this application embodiment uses the atomizing core 20 described above. The atomizing core 20 has low manufacturing cost, which helps to reduce the manufacturing cost of the electronic atomizing device 1.
