Description

Technical Field

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

[0002] Electronic atomizing devices, as a substitute for traditional cigarettes, typically consist of a hollow shell and a power supply and atomizing coil housed within it. The atomizing coil usually includes a wicking element and a heating element. The power supply provides power to the heating element. The shell also contains an atomization channel and a reservoir for supplying atomized liquid to the atomizing coil. The wicking element guides the atomized liquid from the reservoir to the heating element, which heats the liquid in the reservoir to form an inhalable aerosol that flows into the atomization channel. Compared to traditional cigarettes, electronic atomizing devices offer advantages such as no tar, no ash, and no open flame, effectively avoiding the various harmful substances produced when traditional cigarettes are lit.

[0003] In related technologies, atomizer cores typically employ a rigid porous body, such as porous ceramic or porous glass, to mount the heating wire. To ensure the liquid conductivity of the rigid porous body, its thickness is usually quite thin. The power supply device typically supplies power to the heating wire via electrode components (such as electrode pins or electrode springs). Specifically, the power supply device uses the electrode components to abut against the electrode portion of the heating wire to form a circuit. Therefore, during product assembly, the rigid porous body is prone to cracking due to the force exerted by the electrode components. To reduce this, the force applied by the electrode components is usually reduced; however, this can easily lead to poor contact between the electrode components and the electrode portion of the heating wire.

[0043] Reference Figures 1 to 15 The atomizing core according to an embodiment of this application includes a dense substrate 100, a rigid porous body 200, and a heating element 300.

[0044] Specifically, the dense substrate 100 has a first receiving groove 110 that extends through the dense substrate 100 along a first direction. The rigid porous body 200 has a portion that is housed within the first receiving groove 110. The rigid porous body 200 has an atomizing surface and a liquid-absorbing surface that are disposed opposite each other along the first direction. The heating element 300 includes a heating part 310 and an electrode part 320. At least the heating part 310 is disposed on the atomizing surface of the rigid porous body 200. The dense substrate 100 is provided with a support part 120 for supporting the electrode part 320.

[0045] It should be noted that the first direction is the X direction in the attached diagram.

[0046] Specifically, the portion of the rigid porous body 200 housed within the first receiving groove 110 is adapted to the shape and size of the first receiving groove 110.

[0047] By providing a dense substrate 100 independent of the rigid porous body 200, and providing a support portion 120 on the dense substrate 100 for supporting the electrode portion 320 of the heating element 300, the support portion 120 can withstand the force applied to the electrode portion 320 by the electrode component, thereby preventing the rigid porous body 200 from cracking due to the force applied to the electrode portion 320 by the electrode component. Based on this, when assembling the product, sufficient force can be applied to the electrode component to reduce the possibility of poor contact between the electrode component and the electrode portion 320.

[0048] It should be noted that in some of the embodiments, the rigid porous body 200 is made of porous ceramic, the dense matrix 100 is made of dense ceramic, and the heating element 300 is a heating wire, and the three are sintered together.

[0049] It should be noted that in some other embodiments, the rigid porous body 200 may also be made of porous glass, which is not limited here.

[0050] Reference Figures 8 to 15 In some embodiments, the dense substrate 100 has at least two independent first receiving grooves 110, each first receiving groove 110 is correspondingly provided with a rigid porous body 200, and each rigid porous body 200 is provided with an independent heating element 300 or a portion of the same heating element 300 is provided with a portion of the heating element 310.

[0051] Reference Figure 10 , Figure 11 , Figure 14 and Figure 15 In some embodiments, for the case where multiple rigid porous bodies 200 are provided, each rigid porous body 200 is provided with an independent heating element 300, and the dense substrate 100 is provided with a support portion 120 corresponding to each electrode portion 320.

[0052] Reference Figure 8 , Figure 9 , Figure 12 and Figure 13 In some other embodiments, for cases where multiple rigid porous bodies 200 are provided, only one heating element 300 may be provided. Specifically, the heating element 300 has multiple heating parts 310 arranged in series, and the multiple heating parts 310 arranged in series are respectively arranged on the atomizing surface of the multiple rigid porous bodies 200. There is a common electrode part 330 between two adjacent heating parts 310. The common electrode part 330 spans between two adjacent first receiving grooves 110. The dense substrate 100 is provided with a support part 120 corresponding to the electrode parts 320 at both ends of the heating element 300. In this case, the solid part of the dense substrate 100 used to separate the two adjacent first receiving grooves 110 constitutes the support part for supporting the common electrode part 330.

[0053] Reference Figures 2 to 7 as well as Figure 9 , Figure 11 , Figure 13 and Figure 15In some embodiments, the support portion 120 is a protruding structure, and the rigid porous body 200 is provided with a clearance through hole 210 corresponding to the support portion 120. The support portion 120 passes through the clearance through hole 210, which helps to improve the bonding strength between the rigid porous body 200 and the dense matrix 100, thereby helping to prevent the rigid porous body 200 from detaching from the dense matrix 100, and thus helping to improve the stability and reliability of the structure.

[0054] Reference Figures 2 to 7 as well as Figure 9 , Figure 11 , Figure 13 and Figure 15 In some embodiments, a second receiving groove 130 connected to the first receiving groove 110 is provided on the side of the dense substrate 100 near the atomization surface of the rigid porous body 200. The cross-sectional dimension of the second receiving groove 130 is larger than that of the first receiving groove 110. The rigid porous body 200 has a portion that is accommodated within the second receiving groove 130, and a support portion 120 is provided on the bottom wall of the second receiving groove 130. By providing a second receiving groove 130 with a cross-sectional dimension larger than that of the first receiving groove 110, both the first receiving groove 110 and the second receiving groove 130 accommodate a portion of the rigid porous body 200. On the one hand, this helps to improve the bonding strength between the rigid porous body 200 and the dense substrate 100, thereby helping to prevent the rigid porous body 200 from detaching from the dense substrate 100. On the other hand, it allows the dense substrate 100 to better protect the rigid porous body 200. In addition, when sintering the hard porous body 200, the walls of the first receiving tank 110 and the second receiving tank 130 can act as templates to restrict the flow of slurry. Compared with setting up a template, this is beneficial to improve the sintering efficiency of the hard porous body 200 and reduce the sintering cost of the hard porous body 200.

[0055] Specifically, the portion of the rigid porous body 200 housed within the second receiving groove 130 is adapted to the shape and size of the second receiving groove 130, while the through hole 210 is disposed within the portion of the rigid porous body 200 housed within the second receiving groove 130.

[0056] When the dense substrate 100 has at least two independent first receiving grooves 110, a second receiving groove 130 is provided for each first receiving groove 110. In this case, if an independent heating element 300 is provided on each rigid porous body 200, a support portion 120 is provided on the bottom wall of each second receiving groove 130.

[0057] Reference Figure 3In some embodiments, the cross-sectional dimension of the first receiving groove 110 near the liquid absorption surface is larger than the cross-sectional dimension of the end near the atomizing surface, so as to limit the rigid porous body 200 from detaching from the dense matrix 100, thereby improving the stability and reliability of the structure.

[0058] It should be noted that in some other embodiments, the cross-sectional dimension of the end of the second receiving groove 130 near the liquid absorption surface may be larger than the cross-sectional dimension of the end near the atomizing surface, so as to limit the rigid porous body 200 from detaching from the dense matrix 100. This is not limited here.

[0059] It should be noted that in some other embodiments, the cross-sectional dimension of the end of the first receiving groove 110 near the liquid absorption surface may be larger than the cross-sectional dimension of the end near the atomizing surface, and the cross-sectional dimension of the end of the second receiving groove 130 near the liquid absorption surface may be larger than the cross-sectional dimension of the end near the atomizing surface, so as to restrict the rigid porous body 200 from detaching from the dense matrix 100, which is not limited here.

[0060] Reference Figures 1 to 3 as well as Figure 7 In some embodiments, the portion of the rigid porous body 200 housed within the second receiving groove 130 has a protrusion 220 on its side, and the sidewall of the second receiving groove 130 has a recess 131 that cooperates with and limits the protrusion 220. This is beneficial to improving the bonding strength between the rigid porous body 200 and the dense matrix 100, thereby preventing the rigid porous body 200 from detaching from the dense matrix 100, and further improving the stability and reliability of the structure.

[0061] Reference Figure 4 as well as Figures 8 to 11 In some other embodiments, the recess 131 described above can also be replaced by a notch 132, which is not limited here. The notch 132, in conjunction with the protrusion 220, helps to limit the movement and also improves the bonding strength between the rigid porous body 200 and the dense matrix 100. Furthermore, during the sintering of the rigid porous body 200, the notch 132 helps to reduce the narrow slurry filling area, thereby improving the slurry's fluidity and reducing the difficulty of filling the slurry.

[0062] Reference Figure 5 and Figure 6 In some embodiments, the bottom wall of the second receiving groove 130 is provided with a connecting hole 133, and the rigid porous body 200 has a portion that is accommodated in the connecting hole 133. This is beneficial to improving the bonding strength between the rigid porous body 200 and the dense matrix 100, thereby preventing the rigid porous body 200 from detaching from the dense matrix 100, and thus improving the stability and reliability of the structure.

[0063] Specifically, the portion of the rigid porous body 200 housed within the connecting hole 133 is adapted to the shape and size of the connecting hole 133.

[0064] The connecting hole 133 can be a through hole or a blind hole, and there is no limitation here.

[0065] Reference Figure 6 In some embodiments, the connecting hole 133 is tapered, and the cross-sectional dimension of the end of the connecting hole 133 near the liquid absorption surface is larger than the cross-sectional dimension of the end near the atomizing surface, so as to restrict the rigid porous body 200 from detaching from the dense matrix 100, thereby helping to further improve the stability and reliability of the structure.

[0066] It should be noted that in some other embodiments, the connecting hole 133 may also be stepped, and the cross-sectional dimension of the end of the connecting hole 133 near the liquid absorption surface is larger than the cross-sectional dimension of the end near the atomizing surface. In this case, the rigid porous body 200 can also be restricted from detaching from the dense matrix 100.

[0067] Reference Figure 8 , Figure 9 , Figure 12 and Figure 13 In some embodiments, when multiple rigid porous bodies 200 are provided and correspondingly multiple second receiving grooves 130 are provided, the dense substrate 100 is used to separate the solid portions of two adjacent second receiving grooves 130 to form a partition 140. When the heating element 300 has multiple heating elements 310 arranged in series and there is a common electrode portion 330 between two adjacent heating elements 310, the partition 140 is also used to support the common electrode portion 330. The partition 140 is also provided with a protruding reinforcing portion 141, and the corresponding side of the rigid porous body 200 is provided with a groove 230 that mates with the reinforcing portion 141. On the one hand, the reinforcing part 141 can enhance the structural strength of the partition part 140, thereby improving the stability and reliability of the structure. On the other hand, the reinforcing part 141 can cooperate with the groove 230 to improve the bonding strength between the rigid porous body 200 and the dense matrix 100, thereby preventing the rigid porous body 200 from detaching from the dense matrix 100, and further improving the stability and reliability of the structure.

[0068] Reference Figure 5 In some embodiments, the dense substrate 100 is provided with only one support portion 120 for each electrode portion 320, and the orthographic projection of the electrode portion 320 along the first direction falls completely on the corresponding support portion 120, so that the support portion 120 can better support the electrode portion 320 and withstand the force applied by the electrode.

[0069] Reference Figure 7In some other embodiments, the dense substrate 100 is provided with a plurality of spaced support portions 120 for each electrode portion 320. When sintering the hard porous body 200, the obstruction effect of the support portions 120 on the slurry can be reduced, and the narrower slurry filling area can be reduced, thereby improving the fluidity of the slurry and reducing the difficulty of filling the slurry.

[0070] Reference Figures 10 to 15 In some embodiments, the dense substrate 100 is further provided with an air passage 150 extending through itself in a first direction, and all the first receiving slots 110 are spaced around the air passage 150 to accommodate electronic atomizing devices where the airflow needs to pass through the atomizing core.

[0071] It should be noted that in some other embodiments, the second receiving groove 130 described above may not be provided, and this is not a limitation. Specifically, the support portion 120 is disposed at the edge of the first receiving groove 110, and the rigid porous body 200 has a portion extending to the support portion 120 and used for passing through the support portion 120.

[0072] It should be noted that in some other embodiments, the support portion 120 may also be flush with the corresponding end face of the first receiving groove 110 (i.e., the end face near the atomizing surface of the rigid porous body 200), that is, the support portion 120 is not a protruding structure, and this is not limited here. Specifically, the corresponding electrode portion 320 extends to the support portion 120 and is used to hold the electrode, in which case the second receiving groove 130 mentioned above is not required.

[0073] It should be noted that when the atomizing core has multiple heating elements 300 or the heating element 300 has multiple heating parts 310, the shape, size, resistance, etc. of the heating elements 300 or heating parts 310 corresponding to different hard porous bodies 200 can be the same or different, and no limitation is made here.
