[0039] Please refer to Figures 1 to 5 together. Now, the heating component 10 provided in the embodiment of the present application will be described. The heating component 10 is used to be installed in the atomization tube 20 of the atomization core, and the atomization core is applied to an electronic atomizer. Among them, the electronic atomizer can be used in different fields, such as medical atomization, e-cigarette atomization, etc.

[0040] Please refer to Figure 1 and Figure 2 . The heating component includes a plurality of heating mesh sheets 11, spacers 12, and an electrode assembly 13. The plurality of heating mesh sheets 11 are sequentially arranged at intervals along a preset direction; the spacers 12 are disposed between two adjacent heating mesh sheets 11 for controlling the distance between two adjacent heating mesh sheets 11; the electrode assembly 13 includes a first electrode pin 131 and a second electrode pin 132 that respectively extend along the length direction of the atomization core; wherein, the first electrode pin 131 is electrically connected to any position of the spacer 12, and the second electrode pin 132 is electrically connected to one end of the heating mesh sheet 11 away from the spacer 12.

[0041] The inner wall of the atomization tube 20 is permeable to the liquid aerosol - generating matrix to the heating mesh 11. The heating mesh 11 is electrically connected to the power supply assembly of the electronic atomizer through the first electrode pin 131 and the second electrode pin 132, so that the power supply assembly can supply power to the heating mesh 11 through the first electrode pin 131 and the second electrode pin 132. The heating mesh 11 is energized to generate heat to heat and atomize the aerosol - generating matrix to generate aerosol, and the generated aerosol is discharged from the air outlet end of the electronic atomizer.

[0042] Optionally, the preset direction is the circumferential direction of the atomization tube 20, that is, a plurality of heating meshes 11 are arranged at intervals in the circumferential direction of the atomization tube 20. Of course, the preset direction can also be the length direction of the atomization tube 20, that is, a plurality of heating meshes 11 are arranged at intervals in the length direction of the atomization tube 20.

[0043] Optionally, the material of the spacer 12 can be the same as or different from that of the heating mesh 11, and can be specifically selected according to the actual situation. When the material of the spacer 12 is the same as that of the heating mesh 11, the spacer 12 can be integrally formed with two adjacent heating meshes 11. When the material of the spacer 12 is different from that of the heating mesh 11, the spacer 12 can be welded between two adjacent heating meshes 11.

[0044] Optionally, the first electrode pin 131 is arranged at the middle position of the spacer 12, such as Figure 1 . Of course, the first electrode pin 131 can also be arranged on the side of the spacer 12. For example, the first electrode pin 131 is arranged at the side position of the spacer 12 close to the heating mesh 11.

[0045] Optionally, the first electrode pin 131 is the positive electrode pin and the second electrode pin 132 is the negative electrode pin. Or, the first electrode pin 131 is the negative electrode pin and the second electrode pin 132 is the positive electrode pin.

[0046] Compared with the prior art, for the heating component provided by the present application, by arranging a plurality of heating meshes 11 at intervals in the preset direction, the distance between the heating meshes 11 is increased. By arranging the spacer 12 between two adjacent heating meshes 11 to control the distance between two adjacent heating meshes 11, the two adjacent heating meshes 11 can be stably kept in an interval - arranged state, which is beneficial to reducing the thermal radiation influence between the heating meshes 11, effectively avoiding heat concentration in the atomization tube 20, and further being beneficial to reducing the temperature of the air outlet end of the electronic atomizer and improving the user experience.

[0047] In addition, by electrically connecting the first electrode pin 131 to any position of the spacer 12, the first electrode pin 131 is electrically connected to the heating mesh 11 through the spacer 12, enabling the spacer 12 to also have the functions of conduction and support, realizing the multi-functionality of the spacer 12. Moreover, by electrically connecting the first electrode pin 131 to the spacer 12, the first electrode pin 131 is integrated on the spacer 12, so that the first electrode pin 131 does not need to occupy additional installation space, with a reasonable layout and a compact structure, which is beneficial to reducing the volume of the heating component 10 and the space occupied by the heating component 10.

[0048] In some embodiments of the present application, please refer to Figure 1 and Figure 3 , the heating component 10 includes two heating meshes 11, and the two heating meshes 11 are attached to the inner wall of the atomization tube 20 and are arranged at intervals opposite to each other. By arranging the two heating meshes 11 at intervals opposite to each other, it effectively prevents the two heating meshes 11 from being affected by a large amount of thermal radiation between them, which is beneficial to reducing the heat in the atomization tube 20. In addition, by attaching the two heating meshes 11 to the inner wall of the atomization tube 20, the number of heating meshes 11 is small, the structure is simple, and it is convenient for processing and assembly.

[0049] Optionally, the atomization tube 20 includes two inner wall surfaces 201 that are far away from each other, and the two heating meshes 11 are respectively attached to the two inner wall surfaces 201. Since the two inner wall surfaces 201 of the atomization tube 20 are far away from each other, when the two heating meshes 11 are respectively attached to the two inner wall surfaces 201, the two heating meshes 11 are in an interval state of being far away from each other, effectively preventing the two heating meshes 11 from approaching each other.

[0050] In some embodiments of the present application, the heating component 10 includes three heating meshes 11, the three heating meshes 11 are attached to the inner wall of the atomization tube 20, and the three heating meshes 11 are evenly distributed around the central axis of the atomization tube 20, and the three heating meshes 11 are arranged at intervals.

[0051] By attaching the three heating meshes 11 to the inner wall of the atomization tube 20 and the three heating meshes 11 being evenly distributed around the central axis of the atomization tube 20, the liquid aerosol generation matrix on the inner wall of the atomization tube 20 is uniformly atomized, making the aerosol at the air outlet end more concentrated and full, which is beneficial to improving the user experience.

[0052] Optionally, the atomizing tube 20 includes three inner wall surfaces 201 which are distributed around the central axis of the atomizing tube 20, and the three inner wall surfaces 201 are spaced apart from each other. The three heating mesh sheets 11 are respectively attached to the three inner wall surfaces 201. Since the three inner wall surfaces 201 are spaced apart from each other, by attaching the three heating mesh sheets 11 to the three inner wall surfaces 201 respectively, the heating mesh sheets 11 are stably in a spaced-apart state from each other, which is beneficial to reducing the influence of thermal radiation between the heating mesh sheets 11.

[0053] In some embodiments of the present application, please refer to Figure 1 and Figure 2 , at least one hollow hole 121 is provided on the spacer 12. By providing the hollow hole 121 on the spacer 12, it effectively avoids the heat transfer between adjacent heating mesh sheets 11 through the spacer 12, avoids the spacer 12 from generating more thermal radiation, and at the same time is beneficial to reducing the weight of the spacer 12, which helps to realize the lightweight of the heating component.

[0054] Optionally, one hollow hole 121 is provided on the spacer 12, and the hollow hole 121 is provided at the center of the spacer 12. By providing a relatively large hollow hole 121 at the center of the spacer 12, the processing is simple, which is beneficial to improving the production efficiency.

[0055] Optionally, a plurality of hollow holes 121 are provided on the spacer 12, and the plurality of hollow holes 121 are evenly provided on the spacer 12. By providing a plurality of evenly distributed hollow holes 121 on the spacer 12, it is beneficial to reduce the weight of the spacer 12, and at the same time effectively ensures the structural strength of the spacer 12, making the spacer 12 not easily deformed.

[0056] In some embodiments of the present application, the number of the first electrode pins 131 is one, the number of the second electrode pins 132 is also plural, and the number of the second electrode pins 132 is equal to the number of the heating mesh sheets 11. The first electrode pin 131 is electrically connected to each heating mesh sheet 11 through the spacer 12; the plurality of second electrode pins 132 are respectively electrically connected to the plurality of heating mesh sheets 11 one by one. For example, the number of the heating mesh sheets 11 is two, the number of the spacers 12 is one, and the spacer 12 is connected to one side of the two heating mesh sheets 11. The first electrode pin 131 is arranged on the spacer 12, the number of the second electrode pins 132 is also two, and the two second electrode pins 132 are respectively electrically connected to the other sides of the two heating mesh sheets 11, as Figure 1 .

[0057] By electrically connecting the first electrode pin 131 to each heating mesh 11, it is realized that multiple heating meshes 11 share one first electrode pin 131, which is beneficial to reducing the number of first electrode pins 131, simplifying the structure, and making the performance of the heating component more stable and reliable. By using multiple second electrode pins 132 to be respectively and electrically connected to multiple heating meshes 11 one by one, the on-off of each second electrode pin 132 can be independently controlled, so as to independently control the heating conditions of each heating mesh 11. In this way, the heating power of the heating component 10 can be adjusted according to requirements. For example, when the temperature at the air outlet end is too high, part of the heating meshes 11 can be powered on to generate heat, and the other part of the heating meshes 11 can be powered off to reduce the heating power of the entire heating component 10, thereby reducing the temperature at the air outlet end.

[0058] Please refer to Figures 2 to 5 , this embodiment of the present application further provides an atomizing core, including an atomizing tube 20 and the heating component 10 of any one of the above, and the heating component 10 is installed in the atomizing tube 20; wherein, multiple heating meshes 11 of the heating component 10 are attached to the inner wall of the atomizing tube 20.

[0059] Compared with the prior art, the atomizing core provided by the present application adopts the above-mentioned heating component. The above-mentioned heating component arranges multiple heating meshes 11 at intervals in a preset direction in sequence to increase the distance between the heating meshes 11. The spacer 12 is arranged between two adjacent heating meshes 11 to control the distance between two adjacent heating meshes 11, so that two adjacent heating meshes 11 are stably maintained in a spaced state, which is beneficial to reducing the influence of thermal radiation between the heating meshes 11, effectively avoiding heat concentration in the atomizing tube 20, and further being beneficial to reducing the temperature at the air outlet end of the electronic atomizer and improving the user experience.

[0060] In addition, by electrically connecting the first electrode pin 131 to any position of the spacer 12, it is realized that the first electrode pin 131 is electrically connected to the heating mesh 11 through the spacer 12, so that the spacer 12 also has the functions of conduction and support, realizing the multi-function of the spacer 12. And by electrically connecting the first electrode pin 131 to the spacer 12, the first electrode pin 131 is integrated on the spacer 12, and the first electrode pin 131 does not need to occupy additional installation space, with reasonable layout and compact structure, which is beneficial to reducing the volume of the heating component 10 and reducing the space occupied by the heating component 10.

[0061] The shape of the heating component 10 is adapted to the shape of the atomizing tube 20. Specifically, the radial cross-section of the heating component 10 is adapted to the radial cross-section of the atomizing tube 20. For example, the radial cross-section of the atomizing tube 20 is one of an ellipse, a rectangle, and a trapezoid. Thus, the radial cross-section of the heating component 10 can also be one of an ellipse, a rectangle, and a trapezoid adapted to the atomizing tube 20. Among them, when the radial cross-section of the heating component 10 is one of an ellipse, a rectangle, and a trapezoid, the radial cross-section of the heating mesh 11 can be U-shaped, and the heating mesh 11 is attached to the narrow wall surface of the atomizing tube 20, effectively ensuring the stability of the heating mesh 11 attached to the inner wall of the atomizing tube 20 and preventing the heating meshes 11 from approaching each other, such as Figure 3 .

[0062] In some embodiments of the present application, please refer to Figure 2 and Figure 4 , the atomizing tube 20 includes a tube body 21 and an oil guiding cotton 22 accommodated in the tube body 21, and the oil guiding cotton 22 is clamped between the tube body 21 and the heating mesh 11.

[0063] The tube body 21 is a rigid tube, and the tube body 21 is used to fix and accommodate the oil guiding cotton 22 and the heating component 10. Optionally, the oil guiding cotton 22 is annular, and when the oil guiding cotton 22 is accommodated in the tube body 21, the shape of the oil guiding cotton 22 is adapted to the tube body 21.

[0064] Optionally, the tube body 21 is one of a metal tube body 21 and a plastic tube body 21. Among them, the metal tube body 21 has a stable structure and is not easily deformed, and can relatively stably keep the multiple heating meshes 11 away from each other. The plastic tube body 21 is light in weight and low in cost, which is beneficial to reducing the weight of the atomizing core and the manufacturing cost of the atomizing core.

[0065] In some embodiments of the present application, please refer to Figure 5 , the atomizing tube 20 is a porous ceramic body. Among them, the porous ceramic body can adsorb a large amount of liquid aerosol generating matrix through its own large number of small pores, and the porous ceramic body can quickly and timely penetrate the liquid aerosol generating matrix onto the heating mesh 11.

[0066] By using the porous ceramic body for the atomizing tube 20, the oil guiding cotton 22 can be omitted, the structure of the atomizing core is simplified, which helps the atomizing core to be miniaturized and lightweight, and the structure of the porous ceramic body is stable and durable, and it is not easy to have the phenomenon of core coking, and the smoke taste is delicate.

[0067] The embodiment of the present application also provides an electronic atomizer, including a housing, a power supply component accommodated in the housing, and the atomizing core according to any one of the above embodiments. The atomizing core is accommodated in the housing and is electrically connected to the power supply component, and the power supply component is used to supply power to the atomizing core.

[0068] Specifically, the heating mesh 11 is electrically connected to the power supply assembly through the first electrode pin 131 and the second electrode pin 132, and the power supply assembly supplies power to the heating mesh 11 through the first electrode pin 131 and the second electrode pin 132, as Figure 1 .

[0069] For the electronic atomizer provided in this application, the above-mentioned atomization core is adopted. The heating component of the above-mentioned atomization core arranges a plurality of heating meshes 11 at intervals in a preset direction in sequence to increase the distance between the heating meshes 11. The spacer 12 is arranged between two adjacent heating meshes 11 and is used to control the distance between two adjacent heating meshes 11, so that the two adjacent heating meshes 11 are stably maintained in a spaced state, which is beneficial to reducing the thermal radiation influence between the heating meshes 11, thereby effectively avoiding the concentration of heat in the atomization tube 20, and further being beneficial to reducing the temperature of the air outlet end of the electronic atomizer and improving the user experience.

[0070] In addition, by electrically connecting the first electrode pin 131 to any position of the spacer 12, the first electrode pin 131 is electrically connected to the heating mesh 11 through the spacer 12, so that the spacer 12 also has the functions of conduction and support, realizing the multi-function of the spacer 12. And by electrically connecting the first electrode pin 131 to the spacer 12, the first electrode pin 131 is integrated on the spacer 12, and the first electrode pin 131 does not need to occupy extra installation space, with reasonable layout and compact structure, which is beneficial to reducing the volume of the heating component 10 and reducing the space occupied by the heating component 10.

[0071] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
