Therefore, the specification and drawings are only for the purpose of clearly describing a particular embodiment and do not imply a required composition and / or sequence.

[0035] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0036] The atomizer core assembly of the present application includes an atomizer core and at least one electrode sheet. A first conductive part is connected to the electrode sheet, and the first conductive part has a connecting cavity; the atomizer core has at least one second conductive part, one end of the second conductive part abuts against the cavity wall of the connecting cavity, and forms a surface contact, so that an electrical connection is formed between the second conductive part and the first conductive part. Among them, the contact area between the second conductive part and the first conductive part is increased by the surface contact between the second conductive part and the inner side wall of the connecting cavity, so as to keep the resistance between the atomizer core and the electrode sheet stable when powered on. At the same time, the cavity wall of the connecting cavity can be used to limit the second conductive part to prevent the second conductive part from generating a large range of relative movement, which is conducive to alleviating the phenomenon of poor contact and improving the stability of the atomizer core assembly.

[0037] Some embodiments of the atomizer core assembly, atomizer, and atomization device provided by the present application are described below with reference to the accompanying drawings.

[0038] In one embodiment of the first aspect of the present application, an atomizer core assembly 100 is provided. Figure 1 、 Figure 2 As shown, the atomizer core assembly 100 includes an electrode sheet 11 and an atomizer core 12 . There is at least one electrode sheet 11, and a first conductive portion 111 is connected to the electrode sheet 11. The first conductive portion 111 is electrically connected to the electrode sheet 11, and the first conductive portion 111 has a connecting cavity 1111. Correspondingly, the atomizer core 12 has a second conductive portion 121 at one end facing the electrode sheet 11, and the number of the second conductive portions 121 is the same as the number of the electrode sheets 11. The second conductive portion 121 extends into the connecting cavity 1111 of the first conductive portion 111, and abuts against the cavity wall of the connecting cavity 1111, so that a conductive connection is formed between the atomizer core 12 and the electrode sheet 11 through the second conductive portion 121 and the first conductive portion 111. Surface contact is formed at the abutment between the second conductive portion 121 and the connecting cavity 1111 to increase the contact area. At the same time, the connecting cavity 1111 can limit the second conductive portion 121 to a certain extent, preventing the second conductive portion 121 from generating a large range of relative movement.

[0039] It is understood that in the prior art, atomizer cores are typically provided with pins as conductive portions, and these pins are typically cylindrical with arc-shaped sidewalls. Existing atomizer devices typically achieve electrical conductivity by directly contacting the pins of the atomizer core against the flat surface of the electrode sheet. However, the contact between the arc-shaped surface and the flat surface is generally linear, resulting in a small contact area and easily increasing resistance. Furthermore, the contact between the arc-shaped surface and the flat surface is prone to relative motion, which can easily lead to poor contact.

[0040] In this embodiment, surface contact is formed between the cavity wall of the connecting cavity 1111 and the second conductive portion 121, thereby increasing the contact area and facilitating stable resistance. Furthermore, the second conductive portion 121 can be limited to a certain extent, thereby preventing the second conductive portion 121 from making a large relative movement, thereby improving the stability of the atomizer core assembly 100.

[0041] Further, if Figures 1 to 3 As shown, there are two electrode sheets 11, corresponding to the positive electrode and the negative electrode respectively; accordingly, each electrode sheet 11 is connected to a first conductive part 111, and the atomizer core 12 has two second conductive parts 121, each second conductive part 121 abuts against the cavity wall of the connecting cavity 1111 of one of the first conductive parts 111.

[0042] In a further embodiment of the present application, Figure 3 and Figure 4 As shown, a first arc surface segment 1112 is provided on the inner wall of the connecting cavity 1111, and a second arc surface segment 1211 is provided on the outer wall of the second conductive part 121, and the second arc surface segment 1211 abuts against the first arc surface segment 1112 so that the contact surface forms an arc surface, thereby realizing surface contact between the second conductive part 121 and the first conductive part 111.

[0043] The first arc segment 1112 and the second arc segment 1211 can be arc segments on a circular arc with the same radius, or the radius of the first arc segment 1112 can be slightly larger than the radius of the second arc segment 1211 to facilitate assembly of the second conductive portion 121 .

[0044] In a further embodiment of the present application, Figure 3 and Figure 4 As shown, the connecting cavity 1111 is specifically a groove structure, and the groove structure extends along the first direction. The first curved surface segment 1112 is located on the inner wall surface of the groove structure, specifically on the inner side wall or the inner bottom wall. Correspondingly, the second curved surface segment 1211 on the second conductive portion 121 extends into the connecting cavity 1111 from the opening side, and the second curved surface segment 1211 abuts the first curved surface segment 1112 on the inner wall surface of the groove structure to form surface contact.

[0045] The second conductive portion 121 can be entirely extended into the connecting cavity 1111, as shown in FIG. Figure 4 In the example, of course, it is also possible that only the portion of the second conductive portion 121 where the second arc surface segment 1211 is provided extends into the connecting cavity 1111.

[0046] Further, if Figure 4In the example, the second conductive part 121 has a cylindrical structure, that is, any position of the second conductive part 121 in the circumferential direction is the second arc surface segment 1211; accordingly, the connecting cavity 1111 is an arc groove, that is, any position along the circumferential direction on the inner side wall of the connecting cavity 1111 is the first arc surface segment 1112, and the arc radius of the connecting cavity 1111 is not limited to the radius of the second conductive part 121, so as to adapt to the second conductive part 121, so that the outer side wall of the second conductive part 121 can fully contact the inner side wall of the arc groove, thereby further increasing the contact area. Specifically, when the arc radius of the connecting cavity 1111 is the same as the radius of the second conductive part 121, the inner side wall of the arc groove can fully contact the outer side wall of the second conductive part 121.

[0047] It should be noted that, in order to facilitate the second conductive portion 121 to extend from the open side of the arc groove into the interior of the connecting cavity 1111, the width of the open side of the arc groove can be set to be slightly larger than the radius of the second conductive portion 121. Of course, if the assembly process allows, the second conductive portion 121 can also be inserted from the end of the connecting cavity 1111, in which case the width of the open side of the arc groove can also be smaller than the radius of the second conductive portion 121.

[0048] Further, if Figure 5 In the example, the connecting cavity 1111 is specifically a groove structure, and the edge of the opening side of the groove structure is provided with a snap-on structure 1113, and the snap-on structure 1113 has a certain elasticity; the part of the second conductive part 121 having the second arc surface segment 1211 can be clamped into the groove structure from the opening side under the action of pressure, and the second conductive part 121 is clamped between the snap-on structure 1113 and the first arc surface segment 1112, so that the second arc surface segment 1211 on the second conductive part 121 can be in stable contact with the first arc surface segment 1112, preventing the position and size of the contact surface from changing due to relative movement.

[0049] In a further embodiment of the present application, Figure 6 As shown, the connecting cavity 1111 on the first conductive part 111 is specifically a hole-like structure, which extends along the first direction and has at least one end that is a through structure, that is, the connecting cavity 1111 can be a blind hole or a through hole; the first arc surface segment 1112 is located on the inner side wall of the hole-like structure. During assembly, the second conductive part 121 extends into the interior of the connecting cavity 1111 along the first direction, and the second arc surface segment 1211 on the second conductive part 121 abuts against the first arc surface segment 1112 on the inner side wall of the connecting cavity 1111. Among them, the size of the hole-like structure can be set according to actual assembly requirements to adapt to the second conductive part 121, so that the second conductive part 121 can extend into the connecting cavity 1111, but the hole-like structure of the connecting cavity 1111 can limit the second conductive part 121 to prevent the second conductive part 121 from having a large range of relative movement.

[0050] Further, if Figure 6 In the example, the second conductive part 121 is a cylindrical structure, that is, any position of the second conductive part 121 in the circumferential direction is the second arc surface segment 1211; correspondingly, the connecting cavity 1111 is a circular hole structure, that is, any position on the inner side wall of the connecting cavity 1111 along the circumferential direction is the first arc surface segment 1112, so that the second conductive part 121 can form an arc surface contact with the connecting cavity 1111 at any position in the circumferential direction.

[0051] Among them, when the radius of the circular hole structure is the same as the radius of the second conductive part 121, the circumference of the second conductive part 121 can be completely in contact with the connecting cavity 1111; however, in actual application, in order to facilitate assembly, the radius of the circular hole structure can be set to be slightly larger than the radius of the second conductive part 121, for example Figure 6 Examples in .

[0052] It should be noted that the above are only some examples of the second conductive part 121 and the connecting cavity 1111 of the present application. The second conductive part 121 and the connecting cavity 1111 can also adopt other forms that can achieve surface contact. For example, the second conductive part 121 adopts a rectangular cross-section or an elliptical cross-section structure, and the connecting cavity 1111 correspondingly adopts a rectangular or elliptical groove structure or a hole structure, which are not listed one by one here.

[0053] In a further embodiment of the present application, Figure 1 and Figure 7As shown, the atomizer core assembly 100 also includes an atomizer core support 13, an atomizer core sleeve 14, and a liquid absorption structure 15. The atomizer core sleeve 14 extends along a first direction, and the atomizer core 12 is disposed within the atomizer core sleeve 14. A first through hole 141 is defined on the sidewall of the atomizer core sleeve 14 and corresponds to the atomizer core 12. The liquid absorption structure 15 is attached to the outer wall of the atomizer core sleeve 14 and corresponds to the first through hole 141. The liquid absorption structure 15 is capable of absorbing atomized substrate, so that when the atomizer core 12 is energized, the atomized substrate absorbed on the liquid absorption structure 15 is heated and atomized to generate aerosol. The core support 13 defines a mounting cavity 131 extending in a first direction. A second through-hole 132 is formed on the sidewall of the core support 13, communicating with the mounting cavity 131. The core sleeve 14, the core 12, and the liquid-absorbing structure 15 are all disposed within the mounting cavity 131. When assembled in the atomizer 200, the core support 13 supports the core 12 and the core sleeve 14. The mounting cavity 131 communicates with the nozzle 2111 of the atomizer 200, allowing aerosol generated by the core 12 during operation to travel with the inhaled airflow to the nozzle 2111 for inhalation by the user. The second conductive portion 121 of the core 12 extends from the core sleeve 14 and the core support 13 into the connecting cavity 1111 of the first conductive portion 111, thereby forming surface contact with the connecting cavity 1111. In addition, the number of the first through holes 141 can be multiple, so as to increase the heating area of the atomized substrate and improve the atomization efficiency.

[0054] Further, if Figure 7 In the example, the connecting cavity 1111 on the first conductive part 111 is a groove structure. Accordingly, the atomizer core assembly 100 further includes a pressing structure 16; the pressing structure 16 is connected to the end of the atomizer core support 13 facing the electrode sheet 11, and the pressing structure 16 is correspondingly arranged on the opening side of the groove structure. Figure 7 and Figure 8 In the example, the second conductive portion 121 specifically includes a straight segment 1212 and a bent segment 1213. The straight segment 1212 extends along the first direction and extends from one end of the mounting cavity 131 of the atomizer core support 13. The bent segment 1213 is located outside the atomizer core support 13. One end of the bent segment 1213 is connected to the end of the straight segment 1212 that extends outside the mounting cavity 131. The other end of the bent segment 1213 is bent and disposed around the clamping structure 16, and then extends into the connecting cavity 1111 of the first conductive portion 111. The clamping structure 16 abuts against the bent segment 1213 and presses the bent segment 1213 into the connecting cavity 1111, thereby ensuring stable contact between the second conductive portion 121 and the connecting cavity 1111 and preventing separation of the second conductive portion 121 and the connecting cavity 1111.

[0055] Specifically, the compression structure 16 is made of an insulating material. When the groove depth of the groove structure is greater than the maximum width of the second conductive portion 121, a corresponding protrusion structure can be provided on the compression structure 16 toward the groove structure, so that the protrusion structure extends into the groove structure to compress the second conductive portion 121. Alternatively, the compression structure 16 can be provided as a flexible structure so that a portion of the compression structure 16 is pressed into the groove structure during assembly to compress the second conductive portion 121.

[0056] In the embodiment of the second aspect of the present application, an atomizer 200 is provided, such as Figure 7 、 Figure 9 and Figure 10 As shown, the atomizer 200 includes a shell 21 and an atomizer core assembly 100 in any embodiment of the first aspect described above. At least part of the structure of the atomizer core assembly 100 is disposed within the shell 21; the shell 21 has a mouthpiece 2111 at one end in the first direction, and the atomizer core 12 of the atomizer core assembly 100 is connected to the mouthpiece 2111 so that the aerosol generated by the heating of the atomizer core 12 can flow to the mouthpiece 2111 along the suction airflow for inhalation by the user. The electrode sheet 11 of the atomizer core assembly 100 is disposed on the end of the shell 21 away from the mouthpiece 2111, and the first conductive portion 111 extends into the shell 21 and abuts against the second conductive portion 121 of the atomizer core 12; when the electrode sheet 11 is electrically connected to the power supply device, power can be supplied to the atomizer core 12 through the power supply device, so that the atomizer core 12 heats and atomizes the atomization matrix to generate an aerosol.

[0058] In a further embodiment of the present application, Figure 7 、 Figure 9 and Figure 10 As shown, the housing 21 specifically includes an outer shell 211 and a base 212 . The suction nozzle 2111 is located at one end of the shell 211 in the first direction, and the end of the shell 211 away from the suction nozzle 2111 is an open end 2112; the base 212 is detachably connected to the open end 2112 of the shell 211 to assemble into a complete shell 21, and the base 212 and the shell 211 can be connected by snap connection, or by bonding, riveting, bolt connection, etc.; a pole piece mounting groove 2121 is provided on the end of the base 212 away from the suction nozzle 2111, and the electrode piece 11 is installed in the pole piece mounting groove 2121, and a pole piece channel 2122 connected to the pole piece mounting groove 2121 is provided inside the base 212, and the first conductive part 111 is provided in the pole piece channel 2122, and the part of the first conductive part 111 with the connecting cavity 1111 extends into the interior of the shell 211 by the pole piece channel 2122, and then abuts against the second conductive part 121.

[0059] Among them, a corresponding limiting structure or clamping structure can be set on the side wall of the electrode installation groove 2121 to fix the electrode sheet 11; the electrode channel 2122 can be designed according to the shape of the first conductive part 111 to adapt to the first conductive part 111.

[0060] In addition, the atomizer 200 in this embodiment also has all the beneficial effects of the atomizer core assembly 100 in any embodiment of the first aspect above, which will not be repeated here.

[0061] In the embodiment of the third aspect of the present application, an atomization device 300 is provided, such as Figure 9 、 Figure 10 and Figure 11 As shown, the atomization device 300 includes a power supply device 31 and the atomizer 200 in any embodiment of the second aspect mentioned above.

[0063] In addition, the atomization device 300 in this embodiment has all the beneficial effects of the atomizer 200 in any of the above embodiments, which will not be described in detail here.

The snap-fit structure and the slot structure are engaged with each other to form a detachable connection and fixation between the base 212 and the shell 211, and the complete shell 21 is assembled. Two electrode mounting grooves 2121 are provided on the end of the base 212 away from the suction nozzle 2111. The interior of the base 212 is provided with a electrode channel 2122 corresponding to each electrode mounting groove 2121, which connects the electrode mounting groove 2121 and the interior of the shell 211. The up-down direction of the shell is the first direction.

[0067] like Figure 1 、 Figure 7 and Figure 8 As shown, the atomizer core assembly 100 includes an electrode sheet 11, an atomizer core 12, an atomizer core support 13, an atomizer core sleeve 14, and a liquid suction structure 15. There are two electrode sheets 11, corresponding to the positive electrode and the negative electrode respectively; each electrode sheet 11 is connected to a first conductive portion 111, which is conductively connected to one end of the electrode sheet 11; the two electrode sheets 11 are respectively installed in corresponding electrode sheet installation grooves 2121, and the first conductive portion 111 extends into the housing 211 through the corresponding electrode sheet channel 2122 and is located at the end of the base 212 facing the suction nozzle 2111; each first conductive portion 111 has a connecting cavity 1111 extending along the first direction. The connecting cavity 1111 is specifically a circular arc-shaped groove structure with an opening on one side, and any position on the inner sidewall of the groove structure is a first arc segment 1112.

[0068] The atomizer core sleeve 14 and atomizer core support 13 are mounted on the end of the base 212 facing the inhaler nozzle 2111. The atomizer core support 13 defines a mounting cavity 131 extending along a first direction, and a plurality of second through holes 132 are circumferentially defined on the sidewall of the atomizer core support 13. The atomizer core sleeve 14 extends through the mounting cavity 131 along the first direction. The end of the atomizer core sleeve 14 facing the inhaler nozzle 2111 communicates with the inhaler nozzle 2111, and the end of the atomizer core sleeve 14 facing the base 212 abuts against a boss on the inner sidewall of the mounting cavity 131. The atomizer core 12 is disposed within the atomizer core sleeve 14 and abuts against the inner sidewall of the atomizer core sleeve 14. The sidewall of the atomizer core sleeve 14 is circumferentially defined with a plurality of first through holes 141, each of which corresponds to the atomizer core 12. The liquid absorption structure 15 is placed between the atomizer core sleeve 14 and the atomizer core support 13 and attached to the outer wall of the atomizer core sleeve 14. The liquid absorption structure 15 also covers the plurality of first through holes 141. Specifically, the liquid absorption structure 15 can be made of a material such as absorbent cotton that can absorb the atomized matrix. When the atomizer core 12 is energized, the atomized matrix absorbed on the liquid absorption structure 15 is heated and atomized to generate an aerosol. The atomizer core 12 is cylindrical in shape, and accordingly, the atomizer core support 13 also has a cylindrical structure.

[0069] like Figure 7 and Figure 8In the example, a clamping structure 16 is provided on the end of the atomizer core support 13 facing the base 212. The clamping structure 16 is arranged corresponding to the two first conductive parts 111, and the opening side of the groove structure of the first conductive part 111 faces the clamping structure 16. The end of the atomizer core 12 facing the base 212 has two second conductive parts 121. Each second conductive part 121 is a pin structure with a cylindrical cross-section. Any position on the outer wall of the second conductive part 121 is a second arc segment 1211. The second conductive portion 121 specifically includes a straight section 1212 and a bent section 1213. The straight section 1212 extends along the first direction toward a position close to the base 212 and extends out of the mounting cavity 131 of the atomizer core support 13. The bent section 1213 is located outside the atomizer core support 13. One end of the bent section 1213 is connected to the end of the straight section 1212 extending out of the mounting cavity 131. The other end of the bent section 1213 is bent and, from the compression structure 16, is wrapped around to the side of the base 212 into the connecting cavity 1111. The portion of the bent section 1213 extending into the connecting cavity 1111 abuts against the inner sidewall of the connecting cavity 1111, and the contact surface is an arc surface. Through the second conductive portion 121 and the first conductive portion 111, a conductive connection is formed between the atomizer core 12 and the electrode sheet 11. The pressing structure 16 abuts against the bent section 1213 and presses the bent section 1213 into the connecting cavity 1111, thereby ensuring a stable contact between the second conductive portion 121 and the connecting cavity 1111. The radius of the groove structure of the connecting cavity 1111 is slightly larger than the radius of the bent section 1213 of the second conductive portion 121, facilitating assembly of the second conductive portion 121.

[0070] like Figures 7 to 10 In the example, the base 212 also has a liquid infusion port, which is connected to the first through hole 141 of the atomizer core sleeve 14 through a corresponding pipe. When in use, the matrix liquid can be injected through the liquid infusion port, or the atomizer 200 can be assembled on a device storing the matrix liquid, so that the matrix liquid can enter the atomizer core sleeve 14 through the liquid infusion port and be adsorbed on the liquid absorption structure 15 for the atomizer core 12 to heat and atomize to produce an aerosol. Accordingly, a accommodating groove 2123 is provided at a position corresponding to the mounting cavity 131 inside the base 212, and the accommodating groove 2123 is filled with a corresponding liquid absorption piece 2124, which can be used to store the atomized matrix, or to collect the matrix liquid flowing down from the atomizer core sleeve 14.

[0071] One end of the base 212 provided on the atomizer 200 can be assembled with a power supply device or a device having a power supply device, so that the two electrode sheets 11 are electrically connected to the power supply device to supply power to the atomizing core 12 through the power supply device, thereby causing the atomizing core 12 to generate heat to perform an atomization operation on the atomizing matrix.

[0072] In addition, if Figure 7In the example shown in FIG, sealing rings are respectively provided on the outer wall of the base 212 and the outer wall of the atomizer core support 13 to seal the gap between the base 212 and the housing 211 and the gap between the atomizer core support 13 and the housing 211. A corresponding sealing member is also provided at the connection between the atomizer core sleeve 14 and the nozzle 2111 to prevent leakage of the airflow carrying the aerosol.

[0073] It should be noted that, according to the corresponding safety requirements and assembly needs, the housing 21 , the atomizer core sleeve 14 , the atomizer core support 13 , the liquid suction structure 15 , the pressing block structure 16 , etc. are all made of insulating materials.

[0074] The atomizer 200 in this embodiment provides a connecting cavity 1111 with an arc-shaped groove structure on the first conductive part 111, and provides a cylindrical second conductive part 121 in the connecting cavity 1111, so that the second conductive part 121 forms surface contact with the cavity wall of the connecting cavity 1111, thereby increasing the contact area between the second conductive part 121 and the first conductive part 111, which can effectively ensure the stability of the resistance value and prevent the abnormal increase of the resistance value. At the same time, the cavity wall of the connecting cavity 1111 can also be used to limit the second conductive part 121 to a certain extent, preventing the second conductive part 121 from having a large range of relative movement, which is conducive to alleviating the phenomenon of poor contact. The atomizer core assembly 100 has higher working stability and can provide users with a better user experience.

[0075] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, modifications or substitutions can be made based on the concept of the present invention.
