[0035] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various embodiments, and the operation steps involved in each embodiment can also be sequentially adjusted or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing one embodiment, and do not mean that the composition and / or order is necessary.

[0036] In this paper, the serial numbers of components, such as "first", "second", etc., are only used to distinguish the described objects, and do not have any order or technical meaning. The "connection" and "coupling" in the present application include direct and indirect connection (coupling) unless otherwise specified.

[0037] The atomization core assembly provided in the present application is provided with a fixing seat matched with the heating element, the first groove on the fixing seat is used for allowing the conductive structure of the heating element to pass through, and the first protrusion on the atomization core support is used for forming interference fit with the fixing seat to compress the conductive structure, so that the atomization core support can be processed after the fixing seat is assembled to form the first protrusion, thereby replacing the mode of clamping the conductive structure by the groove of the fixing seat and the conductive structure in the prior art during the process of assembling the atomization core support into the fixing seat, so as to prevent the conductive structure from being deformed or damaged due to extrusion and friction of the fixing seat, and prevent the conductive structure from having poor resistance.

[0038] Some embodiments of the atomization core assembly and the atomization device provided in the present application are described below in combination with the drawings.

[0039] In the embodiments of the first aspect of the present application, an atomization core assembly 100 is provided, as shown in Figure 1 、 Figure 2 and Figure 3 , the atomization core assembly 100 comprises an atomization core support 11, a heating element 12 and a fixing seat 13. The atomization core support 11 serves as a support structure and has an atomization cavity 111 extending through in a first direction, and the heating element 12 and the fixing seat 13 are both assembled in the atomization cavity 111. At least one liquid inlet hole 112 is formed in the side wall of the atomization core support 11, so that when the atomization core assembly 100 is applied to an atomization device, the atomization substrate in the atomization device can enter the atomization cavity 111 through the liquid inlet hole 112. The heating element 12 is used for heating the atomization substrate entering the atomization cavity 111 to generate aerosol. The heating element 12 has a conductive structure 121 extending along the first direction and extending out of the atomization cavity 111 to be electrically connected with a power supply device, so as to supply power to the heating element 12. The fixing seat 13 is used for cooperating with the atomization core support 11 to fix the conductive structure 121. The fixing seat 13 is arranged at a position corresponding to one end of the conductive structure 121 of the heating element 12, and the side wall of the fixing seat 13 is provided with a first groove 131, as shown in Figure 2 、 Figure 4 and Figure 5 、 Figure 6In the example shown in FIG. 13, the first groove 131 extends through in the first direction, and the conductive structure 121 of the heating element 12 is arranged in the first groove 131 and extends out of the atomization cavity 111 from the first groove 131. In this case, the inner side wall of the atomization core support 11 has a first protrusion 113 corresponding to the first groove 131, and the first protrusion 113 is in interference fit with the fixing seat 13 to form a connected assembly with the fixing seat 13. At the same time, the first protrusion 113 presses the conductive structure 121 in the first groove 131 of the fixing seat 13 to fix the conductive structure 121. In this case, the number of conductive structures 121 can be one or more, and the number of first grooves 131 can also be one or more. Correspondingly, the first protrusion 113 can also be one or more according to the specific shape structure.

[0040] Since the conductive structure 121 is pressed by the cooperation between the first protrusion 113 and the first groove 131, the first protrusion 113 is not processed before assembly, that is, the inner side wall of the atomization cavity 111 is a smooth surface before assembly, as shown in FIG. 13. Figure 7 In the example shown in FIG. 13, after the fixing seat 13 is assembled into the specified position in the atomization cavity 111 in the first direction, the atomization core support 11 is subjected to a corresponding processing operation (for example, extrusion operation) to form the first protrusion 113 protruding inward on the inner side wall of the atomization cavity 111, as shown in FIG. 13. Figure 8 In the example shown in FIG. 13, the first protrusion 113 is in interference fit with the fixing seat 13 and presses the conductive structure 121.

[0041] It should be noted that in actual application, the structure and thickness size of the atomization core support 11 can be reasonably selected according to specific processing requirements to facilitate extrusion of the atomization core support 11 from the outside to form the first protrusion 113. In addition, the size of the first groove 131 on the fixing seat 13 can be set according to the size of the conductive structure 121 to enable the conductive structure 121 to pass normally during assembly and not to cause extrusion, friction, etc. along the first direction on the surface of the conductive structure 121.

[0042] It can be understood that in common atomization equipment, the conductive structure of the heating element usually adopts a pin structure or a lead structure, and is externally covered with an insulating layer. In the prior art, the conductive structure is directly fixed by the fixing seat, that is, a groove structure slightly smaller than the conductive structure is formed on the fixing seat to form interference fit between the groove structure and the conductive structure during assembly of the fixing seat into the atomization cavity in the first direction, so as to fix the conductive structure. However, the structure using the above assembly method is prone to extrusion and friction of the conductive structure, which can easily cause damage to the insulating layer on the surface of the conductive structure 121 or cause deformation of the conductive structure, thereby causing poor resistance of the conductive structure and affecting normal power supply and work of the heating element.

[0043] The atomizing core assembly 100 in the embodiment is improved and optimized in structure, the first groove 131 of the fixing seat 13 provides a passage for the conductive structure 121 of the heating element 12 to pass out, and when the fixing seat 13 is inserted into the atomizing core support 11 in the axial direction, the conductive structure 121 of the heating element 12 does not need to be clamped and fixed, but after the fixing seat 13 is assembled, the atomizing core support 11 is radially extruded to form the first protrusion 113 on the inner side wall of the atomizing core support 11, and the first protrusion 113 and the fixing seat 13 are connected and fixed, and the conductive structure 121 in the first groove 131 is pressed tightly, thereby avoiding the extrusion and friction between the fixing seat 13 and the conductive structure 121 when the fixing seat 13 is inserted in the axial direction, which can effectively prevent the conductive structure 121 from being deformed or damaged, and can effectively prevent the conductive structure 121 from being deformed or damaged.

[0044] In further embodiments of the application, as shown in Figures 1 to 6 , in the atomizing core assembly 100, the atomizing core support 11 adopts a cylindrical structure to facilitate assembly and airflow passage; the first protrusion 113 on the inner side wall of the atomizing core support 11 extends in the circumferential direction, so that the fixing seat 13 can form an interference fit with the first protrusion 113 at different positions in the circumferential direction. Specifically, the first protrusion 113 can be arranged around the fixing seat 13 for one revolution to further improve the assembly stability.

[0045] Further, as shown in the examples in Figure 2 , Figure 4 and Figure 5 , the fixing seat 13 also adopts a cylindrical structure and is sized to fit the atomizing core support 11. Among them, the outer side wall of the fixing seat 13 is provided with a plurality of first grooves 131, and the plurality of first grooves 131 are arranged at intervals in the circumferential direction. Specifically, as shown in the example in Figure 4 , the outer periphery of the fixing seat 13 is provided with a plurality of first grooves 131 at equal intervals, forming a gear-like structure. When the fixing seat 13 is assembled with the atomizing core support 11, any one of the first grooves 131 can be provided for the conductive structure 121 of the heating element 12 to pass through, so that the fixing seat 13 can be assembled at different angles, reducing the assembly positioning requirements of the fixing seat 13, which is beneficial to simplify the assembly operation and improve the production efficiency.

[0046] In further embodiments of the application, as shown in Figure 9 and Figure 10In the example, the outer wall of the mounting base 13 of the atomizer core assembly 100 has a second groove 132, which corresponds to the first protrusion 113 of the atomizer core support 11 and is arranged circumferentially along the mounting base 13. The size of the second groove 132 is adapted to the first protrusion 113, and at least a portion of the first protrusion 113 extends into the second groove 132 and abuts against the second groove 132 and the conductive structure 121. With the above arrangement, on the one hand, it can form a mutual cooperation with the mounting base 13 to enhance assembly stability, and on the other hand, it can make the first protrusion 113 closer to the bottom of the first groove 131, which is convenient for pressing the conductive structure 121.

[0047] In further embodiments of this application, such as Figure 4 and Figure 11 In the example, the width of the first groove 131 is a first width, and in the radial direction of the fixing seat 13, the first width gradually decreases from the outside to the inside, that is, the first width has a maximum value and a minimum value; correspondingly, the width of the conductive structure 121 is a second width, and the second width is less than the maximum value of the first width, such as... Figure 11 The example is shown below. With the above-described dimensional settings, at least a portion of the conductive structure 121 can extend into the first groove 131 and abut against the sidewall of the first groove 131. Therefore, after the first protrusion 113 is formed, it can radially compress the conductive structure 121, pressing it tightly within the first groove 131. In practical applications, the width of the first groove 131 can be set according to the protrusion size of the first protrusion 113 and the width size of the conductive structure 121, so that the three are mutually compatible, compressing the conductive structure 121 while minimizing its deformation.

[0048] In further embodiments of this application, such as Figure 12 In the example, the conductive structure 121 is a cylindrical structure. Correspondingly, the bottom end of the first groove 131 of the fixing seat 13 has an arc surface structure 1311, and the size of the arc surface structure 1311 is adapted to the conductive structure 121. Thus, after assembly, the outer surface of the conductive structure 121 and the arc surface structure 1311 of the first groove 131 form a surface contact, thereby increasing the contact area. Under the condition that the first protrusion 113 presses the conductive structure 121, the force can be effectively dispersed, and the stability of the conductive structure 121 can be further enhanced.

[0049] In further embodiments of this application, such as Figure 5 and Figure 6As shown, in the atomization core assembly 100, the fixed seat 13 specifically comprises a first section 134 and a second section 135, the first section 134 and the second section 135 are sequentially arranged along the first direction and are connected with each other; the first section 134 is located at one end of the fixed seat 13 close to the heating element 12. Among them, the radial dimension of the first section 134 is smaller than the radial dimension of the second section 135, which can provide more space for the conductive structure 121 on the one hand, and can also mark the assembly direction of the fixed seat 13 on the other hand. In addition, the connection between the outer side wall of the second section 135 and the outer side wall of the first section 134 has an inclined transition surface 136, and in the direction from the second section 135 close to the first section 134 along the first direction, the transition surface 136 gradually inclines to the inner side of the fixed seat 13, so that the first section 134 and the second section 135 form a relatively smooth transition connection, avoiding the presence of a stepped structure, which can further reduce the space occupation and reserve more space for the conductive structure 121 on the one hand, and can prevent the stepped structure from damaging the conductive structure 121 during assembly on the other hand.

[0050] It can be understood that the conductive structure 121 of the heating element 12 usually needs to be arranged in a certain degree of bending manner at the position close to the fixed seat 13 in order to pass through the first groove 131 of the fixed seat 13, such as the examples in Figure 7 and Figure 8 , and a larger space is required for the bending part. Through the structure of the fixed seat 13 in the embodiment, the size design of the first section 134 and the structure design of the transition surface 136 can reserve more space for the bending part of the conductive structure 121 to meet the arrangement requirements.

[0051] In further embodiments of the present application, as shown in Figure 7 and Figure 8 , the first protrusion 113 of the atomization core support 11 is specifically a convex ridge structure, and is formed by extrusion from the outer side of the atomization core support 11, that is, after the extrusion processing is completed, the area extruded on the side wall of the atomization core support 11 is protruded inward as a whole, so that the first protrusion 113 is formed on the inner side wall, and correspondingly, a groove structure is formed on the outer side wall of the atomization core support 11. In actual operation, a cylindrical structure with a relatively thin thickness can be used as the atomization core support 11 to reduce the processing difficulty when extruding the first protrusion 113.

[0052] It should be noted that the first protrusion 113 of the convex ridge structure is only a preferred structure form of the embodiment, and other structure forms can also be used in actual application, for example, the first protrusion 113 can also be a convex point structure arranged at intervals along the circumference.

[0053] In further embodiments of the present application, as shown in Figures 1 to 3As shown, the atomization core assembly 100 further comprises a liquid absorbing structure 14. The liquid absorbing structure 14 is arranged in the atomization cavity 111 of the atomization core support 11, and the liquid absorbing structure 14 corresponds to the liquid inlet hole 112 of the side wall of the atomization core support 11. The liquid absorbing structure 14 has a heating cavity 142 extending through in the first direction, and the heating element 12 is arranged in the heating cavity 142 of the liquid absorbing structure 14 and connected to the liquid absorbing structure 14, that is, the liquid absorbing structure 14 circumferentially covers the outer side of the heating element 12, so that when the atomization core assembly 100 is applied to the atomization device, the liquid absorbing structure 14 can absorb the atomization substrate and uniformly distribute the atomization substrate around the heating element 12, and then the heating element 12 can heat and atomize the atomization substrate to generate aerosol. The airflow generated by the suction action can pass through the heating cavity 142 and carry the aerosol generated by the atomization to the suction end. The liquid absorbing structure 14 can be made of liquid absorbing cotton or other similar structures with adsorption function.

[0054] Further, as shown in Figure 1 , Figure 2 and Figure 6 , the side wall of the atomization core support 11 further has a first opening 114, and the liquid absorbing structure 14 has a protruding portion 141 extending out of the atomization core support 11 through the first opening 114, so that when applied to the atomization device, the protruding portion 141 can be in contact with the atomization substrate in the liquid storage compartment to enhance the adsorption effect. The first opening 114 extends through the atomization core support 11 away from the fixed seat 13 in the first direction, and the liquid absorbing structure 14 can be assembled into the atomization cavity 111 away from the fixed seat 13 of the atomization core support 11 to avoid interference between the protruding portion 141 and the atomization core support 11.

[0055] By arranging the above-mentioned liquid absorbing structure 14, the contact area between the atomization substrate and the heating element 12 can be further expanded, and the atomization substrate can be uniformly distributed on the surface of the heating element 12, which is beneficial to further improve the atomization efficiency.

[0056] In the embodiments of the second aspect of the present application, an atomization device 200 is provided, as shown in Figure 1 and Figure 13 , the atomization device 200 comprises the atomization core assembly 100 of any one of the above-mentioned embodiments of the first aspect, so that the atomization substrate can be heated and atomized by the atomization core assembly 100 to generate aerosol, and then the suction airflow can carry the aerosol to move to the suction end.

[0057] Further, the atomization device 200 further comprises a shell, and the atomization core assembly 100 is arranged in the shell. The shell further comprises a gas channel, a liquid storage compartment and other structures matched with the atomization core assembly 100.

[0058] Furthermore, the atomizing device 200 also includes a power supply device, which is electrically connected to the conductive structure 121 of the atomizing core assembly 100 to supply power to the heating element 12 when energized, so that the heating element 12 heats up and atomizes the atomizing matrix.

[0059] It should be noted that in practical applications, the power supply device can be directly installed inside the housing of the atomizing device 200, or it can be set as an independent device and can be detachably connected to the housing of the atomizing device 200, thus forming a replaceable combination.

[0060] Furthermore, the atomizing device 200 in this embodiment also has all the beneficial effects of the atomizing core assembly 100 in any of the first aspects described above, which will not be repeated here.

[0061] The following describes a specific embodiment of the atomizing core assembly 100 of this application with reference to the accompanying drawings.

[0062] like Figures 1 to 6 As shown, the atomizing core assembly 100 includes an atomizing core support 11, a heating element 12, a fixing base 13, and a liquid absorption structure 14. The atomizing core support 11 has a cylindrical structure and an atomizing cavity 111 extending along a first direction. Multiple liquid inlet holes 112 and a first opening 114 are spaced apart circumferentially on the side wall of the atomizing core support 11, and the first opening 114 extends along the first direction and penetrates one end of the atomizing core support 11. The liquid absorption structure 14 also adopts a cylindrical absorbent cotton structure and is disposed within the atomizing cavity 111 of the atomizing core support 11. The liquid absorption structure 14 corresponds to the liquid inlet holes 112 on the side wall of the atomizing core support 11. The liquid absorption structure 14 has a heating cavity 142 extending along the first direction. The heating element 12 adopts a heating mesh structure and is disposed within the heating chamber 142 of the liquid absorption structure 14. The heating element 12 is connected to the liquid absorption structure 14 so that the liquid absorption structure 14 covers the outer side of the heating element 12 in the circumferential direction, so that the atomized matrix adsorbed by the liquid absorption structure 14 can be evenly distributed on the surface of the heating element 12, thereby heating the atomized matrix through the heating element 12 to generate an aerosol. The side of the liquid absorption structure 14 has a protrusion 141, which extends from the first opening 114 to the outside of the atomizing core support 11. The protrusion 141 can maintain contact with the atomized matrix in the liquid storage chamber to enhance the adsorption effect. During assembly, the liquid absorption structure 14 can be inserted into the atomizing chamber 111 through one end of the first opening 114. The heating element 12 has two conductive structures 121, which are specifically pin structures and extend along the first direction to the outside of the atomizing chamber 111 for electrical connection with the power supply device.

[0063] Correspondingly, the fixing seat 13 adopts a gear-like structure, that is, the fixing seat 13 is also a hollow annular structure, and a plurality of first grooves 131 are arranged on the outer side wall of the fixing seat 13 in a circumferential direction at equal intervals, and each of the first grooves 131 penetrates in the first direction; the fixing seat 13 is also arranged in the atomizing cavity 111 of the atomizing core support 11, and corresponds to one end of the conductive structure 121 of the heating element 12, such as Figure 2 , Figure 4 and Figure 5 , Figure 6 , each of the conductive structures 121 of the heating element 12 penetrates through a corresponding first groove 131 and extends out of the atomizing cavity 111.

[0064] Specifically, as shown in Figure 5 and Figure 6 , the fixing seat 13 specifically includes a first segment 134 and a second segment 135 connected in the first direction; the first segment 134 is located at one end of the fixing seat 13 close to the heating element 12. Among them, the radial dimension of the first segment 134 is smaller than the radial dimension of the second segment 135, and the outer side wall of the second segment 135 has a transition surface 136 arranged obliquely at the connection with the outer side wall of the first segment 134, and in the direction of the first direction from the second segment 135 close to the first segment 134, the transition surface 136 gradually inclines to the inner side of the fixing seat 13, so that the first segment 134 and the second segment 135 form a relatively smooth transition connection, avoiding the appearance of a stepped structure. Among them, the conductive structure 121 has a certain bending part at the position close to the first segment 134 of the fixing seat 13, so that the conductive structure 121 corresponds to the first groove 131 and penetrates through the corresponding first groove 131. The size design of the first segment 134 and the structure design of the transition surface 136 provide more space for the conductive structure 121.

[0065] As an example in Figure 9 and Figure 10 , the inner side wall of the atomizing core support 11 has a first protrusion 113 extending in the circumferential direction of the atomizing core support 11, forming an annular convex structure. Correspondingly, the outer side wall of the fixing seat 13 has a second groove 132 matched with the first protrusion 113, so that at least part of the first protrusion 113 extends into the second groove 132 after assembly, so as to form a fixed assembly of the fixing seat 13 through the cooperation between the first protrusion 113 and the second groove 132. Meanwhile, as an example in Figure 4 and Figure 11 , the width of the first groove 131 is a first width, and in the radial direction of the fixing seat 13, the first width gradually decreases from the outside to the inside; correspondingly, the width of the conductive structure 121 is a second width, and the second width is smaller than the maximum value of the first width, such as Figure 11The conductive structure 121 can be extended into the first groove 131 and abut against the sidewall of the first groove 131, and at least part of the first protrusion 113 is extended into the first groove 131 and presses the conductive structure 121 in the radial direction through the first protrusion 113, so that the conductive structure 121 is pressed in the first groove 131. In the example shown in FIG. 1, the first protrusion 113 is formed on the inner sidewall of the atomizing cavity 111. Figure 3 and Figure 4 In the example shown in FIG. 1, the atomizing core support 11 has a thin-walled cylindrical structure with a small thickness.

[0066] In the production process, the first protrusion 113 can be processed before assembly, such as the example shown in FIG. 1. Figure 7 In the example shown in FIG. 1, the inner sidewall of the atomizing cavity 111 is smooth before assembly, and the space of the first groove 131 is relatively loose during the process of inserting the fixing seat 13 into the atomizing cavity 111 in the first direction, which facilitates the conductive structure 121 to pass through; after the fixing seat 13 is assembled into the designated position of the atomizing cavity 111, the corresponding extrusion processing operation is performed on the outer side of the atomizing core support 11, so that the first protrusion 113 is formed on the inner sidewall of the atomizing cavity 111, such as the example shown in FIG. 1. Figure 8 In the example shown in FIG. 1, the first protrusion 113 is formed in interference fit with the fixing seat 13, and the conductive structure 121 is pressed in the corresponding first groove 131.

[0067] In the example shown in FIG. 1, the first protrusion 113 is formed in interference fit with the fixing seat 13, and the conductive structure 121 is pressed in the corresponding first groove 131.

For those skilled in the art to which the utility model belongs, according to the idea of the utility model, a number of simple deductions, deformations or substitutions can be made.
