It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0043] In addition, the terms "first" and "second" are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality of" means two or more unless otherwise specifically defined.

[0044] Please refer to Figures 1 to 15 together. Now, the atomizing core provided by the embodiments of this application will be described. The atomizing core is applied to an electronic atomizer, and the electronic atomizer can be used in different fields, such as medical atomization, electronic cigarette atomization, etc.

[0045] Please refer to Figures 1 to 3 together. The atomizing core includes an atomizing tube 10 and a heating component 20. The atomizing tube 10 includes a plurality of inner wall surfaces 101 that are away from each other. The heating component 20 includes a plurality of heating mesh sheets 21 that are circumferentially spaced apart along the atomizing tube 10. Each heating mesh sheet 21 corresponds to and adheres to one inner wall surface 101, so that adjacent heating mesh sheets are away from each other.

[0046] Among them, the atomizing tube 10 has an air inlet end 110 and an air outlet end 111 that are arranged opposite to each other. The inner wall of the atomizing tube 10 can permeate the liquid aerosol generation matrix to the heating mesh sheet 21. The aerosol generation matrix is heated and atomized by the energized heating of the heating mesh sheet 21 to form an aerosol. The external air flow sequentially passes through the air inlet end 110 and the air outlet end 111. On the one hand, it can carry away the aerosol generated by the heating mesh sheet 21 for the user to consume. On the other hand, it can ensure the air pressure balance in the atomizing tube 10. The plurality of inner wall surfaces 101 are circumferentially spaced along the atomizing tube 10.

[0047] Compared with the prior art, for the atomizing core provided by this application, by circumferentially spacing the plurality of heating mesh sheets 21 of the heating component 20 along the atomizing tube 10, the distance between adjacent two heating mesh sheets 21 is increased, and each heating mesh sheet 21 corresponds to and adheres to one inner wall surface 101, and the inner wall surfaces 101 are away from each other, so that the plurality of heating mesh sheets 21 are kept away from each other, which is beneficial to reducing the thermal radiation influence between the heating mesh sheets 21, thus effectively avoiding heat concentration in the atomizing tube 10, and further being beneficial to reducing the temperature of the air outlet end 111 of the electronic atomizer and improving the user experience.

[0048] In addition, by corresponding each heating mesh sheet 21 to and adhering it to one inner wall surface 101, the plurality of heating mesh sheets 21 are stably kept away from each other, effectively avoiding the distance between the heating mesh sheets 21 becoming smaller due to the offset of the heating mesh sheets 21 after a long time of use, and further avoiding the temperature of the air outlet end 111 of the electronic atomizer from being too high.

[0049] The shape of the heating component 20 is set according to the shape of the atomization tube 10. Specifically, the radial cross-section of the heating component 20 is adapted to the radial cross-section of the atomization tube 10. Herein, the radial cross-section of the atomization tube 10 refers to the cross-section obtained by intercepting the atomization tube 10 with a plane perpendicular to the axial direction of the atomization tube 10, and the radial cross-section of the heating component 20 refers to the cross-section obtained by intercepting the heating component 20 with a plane perpendicular to the axial direction of the atomization tube 10.

[0050] In some embodiments of the present application, please refer to Figure 3 and Figure 4 , the atomization tube 10 includes two inner wall surfaces 101 which are away from each other; the number of the heating mesh sheets 21 is two, and the two heating mesh sheets 21 are respectively adapted to and attached to the two inner wall surfaces 101 and are arranged at a relative interval. By respectively adapting and attaching the two heating mesh sheets 21 to the two inner wall surfaces 101 and arranging them at a relative interval, the two heating mesh sheets 21 are in a spaced state away from each other, effectively preventing the two heating mesh sheets 21 from being affected by a large amount of thermal radiation between them, which is beneficial to reducing the heat in the atomization tube 10. By respectively adapting and attaching the two heating mesh sheets 21 to the two inner wall surfaces 101, the structure is simple and convenient for processing and assembly.

[0051] Optionally, the radial cross-section of the atomization tube 10 is one of an ellipse, a rectangle, and a trapezoid. The two inner wall surfaces 101 are respectively two narrow wall surfaces in the circumferential direction of the atomization tube 10. It can be understood that the inner wall surface 101 is generally U-shaped. The inner heating mesh sheet 21 is in a U shape capable of being adapted to and attached to the inner wall surface 101, such as Figure 3 and Figure 5 . Thus, by respectively adapting and attaching the two heating mesh sheets 21 to the two narrow wall surfaces in the circumferential direction of the atomization tube 10, it is equivalent to clamping the heating mesh sheets 21 in the atomization tube 10, effectively ensuring the stability of the heating mesh sheets 21 attached to the inner wall surface 101 of the atomization tube 10, making the heating mesh sheets 21 not easily shift relative to the atomization tube 10, effectively avoiding the distance between the heating mesh sheets 21 becoming smaller due to the relative shift of the heating mesh sheets 21 relative to the atomization tube 10, and effectively preventing the heat in the atomization tube 10 from concentrating due to the large amount of thermal radiation between the heating mesh sheets 21, thereby causing the temperature of the air outlet end 111 of the electronic atomizer to be too high. In addition, it is beneficial to increase the contact area between the heating mesh sheets 21 and the atomization tube 10 and improve the atomization efficiency of the atomization core.

[0052] In some embodiments of the present application, please refer to Figure 6 and Figure 7, the atomizing tube 10 includes three inner wall surfaces 101. The three inner wall surfaces 101 are centrosymmetric about the central axis of the atomizing tube 10, and the three inner wall surfaces 101 are away from each other; the number of the heating mesh sheets 21 is two or three. Each heating mesh sheet 21 corresponds to and adheres to one of the inner wall surfaces 101, and the heating mesh sheets 21 are arranged at intervals. Among them, the radial cross-section of the atomizing tube 10 can be, but is not limited to, a triangle or approximately triangular, etc. The inner wall surface 101 is the narrow wall surface of the atomizing tube 10. Understandably, the inner wall surface 101 can be, but is not limited to, V-shaped or U-shaped, etc.

[0053] When there are three inner wall surfaces 101, two or three heating mesh sheets 21 can be selected to adhere to one inner wall surface 101 respectively. Since the three inner wall surfaces 101 are away from each other, the heating mesh sheets 21 are stably in a spaced state away from each other, effectively preventing the heat concentration in the atomizing tube 10 caused by the influence of a large amount of heat radiation between the heating mesh sheets 21.

[0054] In some embodiments of the present application, please refer to Figure 1 and Figure 2 , the atomizing tube 10 includes a tube body 11 and an oil guiding cotton 12 accommodated in the tube body 11. The oil guiding cotton 12 is clamped between the tube body 11 and the heating mesh sheet 21.

[0055] The tube body 11 is a rigid tube, and the tube body 11 is used to fix and accommodate the oil guiding cotton 12 and the heating component 20. Optionally, the oil guiding cotton 12 is annular. When the oil guiding cotton 12 is accommodated in the tube body 11, the shape of the oil guiding cotton 12 is adapted to the tube body 11. In this way, when the heating mesh sheet 21 adheres to the inner wall of the oil guiding cotton 12, the positions of the heating mesh sheets 21 are fixed by the tube body 11, so that the heating mesh sheets 21 are stably maintained in a preset spaced state.

[0056] It should be noted that, please refer to Figure 3 , the shape of the oil guiding cotton 12 can be shaped by the tube body 11. For example, when the radial cross-section of the tube body 11 is kidney-shaped, the radial cross-section of the oil guiding cotton 12 can be circular. By assembling the oil guiding cotton 12 into the tube body 11, the radial cross-section of the oil guiding cotton 12 is deformed into a kidney shape adapted to the tube body 11. Of course, the oil guiding cotton 12 can also be formed into a shape adapted to the tube body 11 during the processing. For example, when the radial cross-section of the tube body 11 is kidney-shaped, the radial cross-section of the oil guiding cotton 12 can be directly processed into a kidney shape adapted to the tube body 11.

[0057] Optionally, please refer to Figure 4, an oil guide groove 112 is provided on the side wall of the tube body 11. The oil guide cotton 12 includes an annular main body portion 121 and an oil guide portion 122 radially extending from the outer wall of the main body portion 121. One end of the oil guide portion 122 away from the main body portion 121 extends out of the tube body 11 through the oil guide groove 112 and extends into the oil storage body of the electronic atomizer for storing the liquid aerosol generating matrix. The liquid aerosol generating matrix in the oil storage body is introduced into the main body portion 121 through the oil guide portion 122. The heat generated by the energization of the heating mesh sheet 21 is transferred to the main body portion 121, causing the aerosol generating matrix on the main body portion 121 to heat up and atomize. Among them, the oil storage body can be an oil storage cotton or an oil storage chamber with an oil storage cavity.

[0058] Optionally, the material of the oil guide cotton 12 can be soft fiber materials such as cotton fiber, non-woven fabric, and blended fiber. The oil guide cotton 12 has good oil absorption performance, is not prone to oil leakage, has a full and real smoke taste, and the oil guide cotton 12 heats up quickly and does not require preheating during use. The fullness of the first puff of smoke is also relatively high. In addition, the material cost of the oil guide cotton 12 is relatively low, which is beneficial to reducing the production cost of the atomization core.

[0059] In some embodiments of the present application, please refer to Figures 1 to 4 , the tube body 11 is a metal tube body. By using a metal tube body for the tube body 11, the structure of the metal tube body is stable and not easily deformed, and it can relatively stably keep the multiple heating mesh sheets 21 away from each other.

[0060] Optionally, the material of the metal tube body can be but not limited to stainless steel, aluminum, copper, nickel, nickel alloy, or titanium alloy, etc. For example, the material of the metal tube body is stainless steel. The stainless steel material has good corrosion resistance and mechanical strength, and strong anti-deformation ability, which is beneficial to extending the service life of the atomization core.

[0061] In some embodiments of the present application, please refer to Figure 8 and Figure 9 , the tube body 11 is a plastic tube body. By using a plastic tube body for the tube body 11, the plastic tube body is light in weight and low in cost, which is beneficial to reducing the weight of the atomization core and the manufacturing cost of the atomization core.

[0062] Optionally, the material of the plastic tube body can be but not limited to polyvinyl chloride (PVC), polycarbonate (PC), or polyethylene terephthalate (PET), etc. For example, the material of the plastic tube body is polyvinyl chloride. Polyvinyl chloride has good mechanical properties and corrosion resistance, and is light.

[0063] In some embodiments of the present application, please refer to Figure 10 and Figure 11 , the atomization tube 10 is a porous ceramic body.

[0064] Specifically, the porous ceramic body is provided with a large number of fine pores, which can provide a large amount of adsorption and storage space for the liquid, enabling the porous ceramic body to adsorb a large amount of liquid aerosol generation matrix, and the porous ceramic body can quickly and timely transport the liquid aerosol generation matrix to the side of the porous ceramic body facing the heating mesh 21, avoiding interference. The heating mesh 21 is energized to heat the liquid aerosol generation matrix adsorbed by the porous ceramic body and atomize it to generate aerosol.

[0065] By using a porous ceramic body for the atomizing tube 10, the oil guiding cotton 12 can be omitted, simplifying the structure of the atomizing core, contributing to the miniaturization and light weight of the atomizing core. Moreover, the structure of the porous ceramic body is stable and durable, not easily prone to the phenomenon of core fouling, and the smoke taste is delicate.

[0066] Optionally, the heating mesh 21 can be made of metal materials such as stainless steel, nickel-chromium or iron-chromium-aluminum. For example, the heating mesh 21 is a stainless steel mesh, which has good electrical conductivity and is durable.

[0067] It should be noted that the sizes of the multiple heating meshes 21 can be the same or different. The multiple heating meshes 21 can be adhered to the inner wall of the atomizing cavity at the same height. For example, the bottoms of the multiple heating meshes 21 are located at the same height of the atomizing tube 10, and / or the tops of the multiple heating meshes 21 are located at the same height of the atomizing tube 10. Of course, the multiple heating meshes 21 can also be arranged in a staggered manner along the axial direction of the atomizing tube 10.

[0068] In some embodiments of the present application, please refer to Figure 2 and Figure 5 , the heating assembly 20 further includes a spacer 22, and the spacer 22 is disposed between two adjacent heating meshes 21.

[0069] By providing the spacer 22 between two adjacent heating meshes 21, it is used to control the distance between two adjacent heating meshes 21, effectively preventing the two adjacent heating meshes 21 from moving closer to each other due to displacement in the atomizing tube 10 after a long time of use. Moreover, the two adjacent heating meshes 21 support each other through the spacer 22, enabling the heating mesh 21 to be more firmly attached to the inner wall surface 101.

[0070] Optionally, the material of the spacer 22 can be the same as or different from that of the heating mesh 21, and can be specifically selected according to the actual situation. When the material of the spacer 22 is the same as that of the heating mesh 21, the spacer 22 can be integrally formed with the two adjacent heating meshes 21. When the material of the spacer 22 is different from that of the heating mesh 21, the spacer 22 can be welded to the two adjacent heating meshes 21.

[0071] In some embodiments of the present application, a spacer 22 is provided between each adjacent pair of heating mesh sheets 21, such that a plurality of heating mesh sheets 21 are connected into an integral body through the spacer 22, effectively enhancing the overall stability of the heating assembly 20, making it not easily deformed, and effectively preventing the heating mesh sheets 21 from approaching each other.

[0072] In some embodiments of the present application, referring to Figure 5 , the spacer 22 is provided with a plurality of hollow holes 221. By providing a plurality of hollow holes 221 in the spacer 22, it effectively prevents heat from being transferred between adjacent heating mesh sheets 21 through the spacer 22, avoids a large amount of heat radiation generated by the spacer 22, and at the same time helps to reduce the weight of the spacer 22, contributing to the lightweight of the atomization core.

[0073] In some embodiments of the present application, referring to Figure 1 and Figure 4 , the atomization core further includes an electrode assembly 30. The electrode assembly 30 is electrically connected to each heating mesh sheet 21, and the electrode assembly 30 is used to electrically connect each heating mesh sheet 21 to the power supply assembly of the electronic atomizer, so that the power supply assembly supplies power to the heating mesh sheets 21 through the electrode assembly 30.

[0074] Optionally, referring to Figure 5 , the electrode assembly 30 includes a first electrode pin 31 and a second electrode pin 32 that respectively extend along the length direction of the atomization tube 10. The first electrode pin 31 is electrically connected to any position of the spacer 22, and the second electrode pin 32 is electrically connected to the end of the heating mesh sheet 21 away from the spacer 22.

[0075] Optionally, the first electrode pin 31 is a positive electrode pin and the second electrode pin 32 is a negative electrode pin. Or, the first electrode pin 31 is a negative electrode pin and the second electrode pin 32 is a positive electrode pin.

[0076] The spacer 22 is a conductor, and the first electrode pin 31 is electrically connected to the heating mesh sheet 21 through the spacer 22.

[0077] By arranging the first electrode pin 31 on the spacer 22, the layout is reasonable and the structure is compact, which is conducive to reducing the volume of the atomization core, and thus helps to achieve the miniaturization of the atomization core.

[0078] In some embodiments of the present application, the number of the first electrode pins 31 is one, the number of the second electrode pins 32 is also multiple, and the number of the second electrode pins 32 is equal to the number of the heating mesh sheets 21. The first electrode pin 31 is electrically connected to each heating mesh sheet 21 through the spacer 22; the multiple second electrode pins 32 are respectively electrically connected to the multiple heating mesh sheets 21 one by one.

[0079] Among them, the first electrode pins 31 and the multiple second electrode pins 32 are parallel to each other, and one end of the first electrode pin 31 and one end of the second electrode pin 32 both extend from the same end of the atomizing tube 10 for electrically connecting to the power supply component of the electronic atomizer.

[0080] By electrically connecting the first electrode pin 31 to each heating mesh 21, it is realized that multiple heating meshes 21 share one first electrode pin 31, which is beneficial to reducing the number of first electrode pins 31, simplifying the structure, and making the performance of the atomizing core more stable and reliable. By respectively electrically connecting multiple second electrode pins 32 to multiple heating meshes 21 one by one, the on-off states of each second electrode pin 32 can be independently controlled, so as to independently control the heating conditions of each heating mesh 21. In this way, the heating power of the heating component 20 can be adjusted according to requirements. For example, when the temperature of the air outlet end 111 is too high, part of the heating meshes 21 can be energized to generate heat, and the other part of the heating meshes 21 can be powered off to reduce the heating power of the entire heating component 20, thereby reducing the temperature of the air outlet end 111.

[0081] It should be noted that in other embodiments, the number of the first electrode pins 31 can also be multiple, and the number of the first electrode pins 31 is the same as the number of the heating meshes 21. The multiple first electrode pins 31 are respectively electrically connected to the multiple heating meshes 21 one by one, effectively avoiding interference between the on-off states of the multiple heating meshes 21.

[0082] In some embodiments of the present application, please refer to Figure 5 , the number of the heating meshes 21 is two, and the two heating meshes 21 are arranged at intervals relatively. A spacer 22 is electrically connected between one side of one heating mesh 21 and one side of the other heating mesh 21. The first electrode pin 31 is arranged on the spacer 22, and the number of the second electrode pins 32 is two. The two second electrode pins 32 are respectively electrically connected to the other sides of the two heating meshes 21.

[0083] In some embodiments of the present application, please refer to Figure 2 and Figure 4 , the atomizing core further includes a fixing seat 40 for fixing the heating component 20. The fixing seat 40 and the heating component 20 are arranged along the axial direction of the atomizing tube 10, and the electrode assembly 30 is limited on the fixing seat 40. By limiting the position of the electrode assembly 30 with the fixing seat 40, it effectively prevents the fixing seat 40 from running off and affecting the stability of the electrical connection between the heating mesh 21 and the power supply component.

[0084] Optionally, please refer to Figure 12 , a plurality of card slots 43 are provided on the outer peripheral side wall of the fixing seat 40, and the first electrode pin 31 and the second electrode pin 32 are respectively and independently clamped in different card slots 43.

[0085] Due to the relatively long lengths of the first electrode pin 31 and the second electrode pin 32, the first electrode pin 31 and the second electrode pin 32 are individually limited by a plurality of card slots 43, effectively preventing the multiple electrode pins from being wound around each other, which may cause unstable electrical connection between the heating mesh 21 and the power supply assembly.

[0086] In some embodiments of the present application, please refer to Figure 8 and Figure 9 , the fixing base 40 is disposed inside the tube body 11. The fixing base 40 is a plastic part and is integrally formed with the tube body 11.

[0087] By using a plastic part for the fixing base 40 and integrally forming it with the tube body 11, the fixing base 40 and the tube body 11 become an integral body. At the same time, it is beneficial to reduce the number of parts of the atomization core, making the overall structure of the atomization core more stable. Meanwhile, it is convenient for processing and assembly, which is conducive to reducing the manufacturing cost of the atomization core.

[0088] In some embodiments of the present application, please also refer to Figure 2 and Figure 3 , the fixing base 40 is received in the air inlet end 110 of the atomization tube 10. The fixing base 40 has a plurality of ventilation areas 41 distributed at intervals. The plurality of ventilation areas 41 are respectively arranged in one-to-one correspondence with the plurality of heating meshes 21, and each ventilation area 41 is provided with an air passage 410.

[0089] By respectively arranging the plurality of ventilation areas 41 with air passages 410 distributed at intervals of the fixing base 40 in one-to-one correspondence with the plurality of heating meshes 21, the outside air flow can uniformly flow to each heating mesh 21 through the air passages 410 of the plurality of ventilation areas 41, so as to efficiently carry away a large amount of aerosol near each heating mesh 21, making the aerosol at the air outlet end 111 more concentrated and full, which is beneficial to improving the user experience.

[0090] Optionally, the inner diameter of the air passage 410 gradually decreases in the direction from the end of the fixing base 40 away from the heating component 20 to the end of the fixing base 40 close to the heating component 20, which is beneficial to increasing the pressure of the air flow flowing from the air passage 410 to the heating mesh 21, and can effectively carry away a large amount of aerosol near the heating mesh 21, making the aerosol at the air outlet end 111 more full.

[0091] Optionally, the number of the heating meshes 21 is two, and their radial cross-sections are both semi-waist-shaped. The radial cross-section of the atomization tube 10 is waist-shaped. The two heating meshes 21 are respectively adapted to and fit with the semi-waist-shaped inner walls on the opposite sides of the atomization tube 10 and are relatively spaced apart. The radial cross-section of the fixing base 40 is waist-shaped, and the semi-waist-shaped areas on the opposite sides of the fixing base 40 respectively form two ventilation areas 41, and the two ventilation areas 41 are respectively arranged in correspondence with the two heating meshes 21.

[0092] By taking the semi-elliptical regions on the opposite sides of the fixed base 40 as the ventilation regions 41, external air flow can respectively and evenly flow to the two semi-elliptical heating mesh sheets 21 through the air channels 410 of the two ventilation regions 41, so as to carry away a large amount of aerosol near the heating mesh sheets 21.

[0093] Optionally, please refer to Figure 13 , one air channel 410 is provided in each of the two ventilation regions 41. Understandably, the two air channels 410 are respectively arranged corresponding to the two heating mesh sheets 21.

[0094] Optionally, please refer to Figure 14 , one air channel 410 is provided in each of the two ventilation regions 41, and a flow channel 420 is provided in the middle region 42 of the fixed base 40. The air channels 410 of the two ventilation regions 41 are interconnected through the flow channel 420 in the middle region 42 to form a waist-shaped channel.

[0095] Optionally, please refer to Figure 15 , a plurality of air channels 410 distributed at intervals are provided in each of the two ventilation regions 41.

[0096] An embodiment of the present application also provides an electronic atomizer, which includes a housing, a power supply component housed in the housing, and the atomization core of any of the above embodiments. The atomization core is housed in the housing, and the power supply component is used to supply power to the atomization core.

[0097] Specifically, the power supply component includes a circuit board and a battery. The battery is electrically connected to the circuit board. One end of the first electrode pin 31 is electrically connected to each heating mesh sheet 21, and the other end is electrically connected to the circuit board. One ends of a plurality of electrode pins are respectively electrically connected to a plurality of heating mesh sheets 21, and the other ends are all electrically connected to the circuit board. The battery supplies power to the heating mesh sheets 21 through the first electrode pin 31 and the second electrode pin 32 under the control of the circuit board, as Figure 5 .

[0098] The electronic atomizer provided by the present application adopts the above atomization core. The above atomization core distributes a plurality of heating meshes of the heating component 20 at intervals along the circumferential direction of the atomization tube 10 to increase the distance between adjacent two heating mesh sheets 21, so that the plurality of heating mesh sheets 21 are in a state of being away from each other, which is beneficial to reducing the thermal radiation influence between the heating mesh sheets 21, thus effectively avoiding heat concentration in the atomization tube 10, and further being beneficial to reducing the temperature of the air outlet end 111 of the electronic atomizer and improving the user experience. In addition, the shape of the atomization tube 10 is adapted to the heating component 20. In this way, the heating mesh sheets 21 can completely and relatively stably adhere to the inner wall of the atomization tube 10, so that the plurality of heating mesh sheets 21 are stably maintained in a state of being away from each other, effectively avoiding the distance between the heating mesh sheets 21 becoming smaller due to the offset of the heating mesh sheets 21 after a long time of use, and further resulting in too high a temperature of the air outlet end 111 of the electronic atomizer.

[0099] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included within the protection scope of the present application.
