[0036] Referring to Figure 1 As shown in the drawings, the embodiments of the present application provide an atomization core, comprising an atomization core support 1, an atomization assembly 2 and a sealing piece 3, the atomization assembly 2 is arranged on the atomization core support 1, and the sealing piece 3 is arranged in the atomization core support 1 and located at the air inlet end of the atomization assembly 2.

[0037] Referring to Figures 2-4 As shown in the drawings, in some embodiments, the atomization core support 1 has a bearing part 11, an air inlet part 12 and an atomization part 13 located at opposite sides of the bearing part 11, in the embodiment, the atomization part 13, the bearing part 11 and the air inlet part 12 are integrally formed, when the atomization core is arranged in an electronic atomization device, the atomization part 13 is located at the suction end of the electronic atomization device, and the air inlet part 12 is located at the air inlet end of the electronic atomization device.

[0038] Referring to Figure 2 , Figure 3As shown in the figure, in some embodiments, the atomization assembly 2 is arranged on the atomization part 13, and the atomization assembly 2 is at least partially arranged in the bearing part 11; the sealing member 3 is arranged in the bearing part 11, and the side wall of the sealing member 3 is tightly attached to the inner wall of the bearing part 11.

[0039] As shown in the figure, Figure 2 , Figure 3 , Figure 5 As shown in the figure, in some embodiments, the air inlet hole 31 is arranged in the sealing member 3, and the air inlet hole 31 is formed with a retaining table 32 on the side close to one end of the atomization assembly 2, and the retaining table 32 forms a liquid storage groove 33 with the inner wall of the bearing part 11.

[0040] When the atomization assembly 2 leaks, the liquid can be stored in the liquid storage groove, and in this embodiment, the leaked atomization liquid enters the liquid storage groove 33 along the inner wall of the bearing part 11.

[0041] The atomization core provided by the embodiment of the present application is provided with a sealing member 3 on the atomization core support 1, which is tightly attached to the bearing part 11 to prevent the atomization liquid of the atomization assembly 2 from leaking from the air inlet side of the atomization core support 1; at the same time, the retaining table 32 is arranged on the sealing member 3 to form the liquid storage groove 33, so as to collect the leaked atomization liquid and avoid the atomization liquid from leaking from the air inlet hole 31, thereby affecting the user experience.

[0042] As shown in the figure, Figures 1-3 As shown in the figure, in some embodiments, the atomization assembly 2 includes a liquid guide 21 and a heating element 22, the liquid guide 21 is sleeved on the atomization part 13, and the bottom of the liquid guide 21 is at least partially arranged in the bearing part 11, and the heating element 22 is arranged in the liquid guide 21.

[0043] The bottom of the liquid guide 21 is at least partially arranged in the bearing part 11, so as to realize the positioning and installation of the liquid guide 21, improve the installation accuracy and efficiency of the liquid guide 21, and avoid the oil leakage caused by the improper installation of the liquid guide 21; at the same time, since the bottom of the liquid guide 21 is at least partially arranged in the bearing part 11, when the atomization assembly 2 leaks, the atomization liquid can flow downward along the inner wall of the bearing part 11, so as to facilitate the collection of the atomization liquid by the liquid storage groove 33, further avoid the atomization liquid from leaking from the air inlet hole 31, and affect the user experience.

[0044] In some embodiments, the liquid guide 21 is made of at least one of cotton, cotton cloth, fiber rope, porous ceramic, foamed metal and foamed graphite.

[0045] In some embodiments, the heating element 22 includes two connecting wires 221 arranged in parallel and a heating mesh connected between the two connecting wires 221. The heating mesh is bent into a ring shape and attached to the inner wall of the liquid guiding element 21. The heating mesh is used to heat and atomize the liquid atomizing liquid transmitted by the liquid guiding element 21.

[0046] In some embodiments, the liquid guiding member 21 includes an inner liquid guiding member 211 and an outer liquid guiding member 212.

[0047] In some embodiments, the inner liquid guiding component 211 is fitted into the atomizing part 13, and the bottom of the inner liquid guiding component 211 is placed into the supporting part 11, and the heating element 22 is installed in the inner liquid guiding component 211; in this embodiment, the distance between the bottom of the inner liquid guiding component 211 and the end of the supporting part 11 near the inner liquid guiding component 21 is 0.5 to 1 mm. Specifically, the distance between the bottom of the inner liquid guiding component 211 and the end of the supporting part 11 near the liquid guiding component can be set to any one of 0.5 mm, 0.75 mm, 1 mm, or a range formed by any two of these values.

[0048] In some embodiments, the external liquid guide 212 is fitted outside the atomizing part 13, and the bottom of the external liquid guide 212 extends toward the air inlet part 12. In this embodiment, the distance between the bottom of the external liquid guide 212 and the end of the support part 11 near the liquid guide 21 is 0.5 to 2 mm. Specifically, the distance between the bottom of the external liquid guide 212 and the end of the support part 11 near the liquid guide 21 can be any one of 0.5 mm, 1 mm, and 2 mm, or a range formed by any two of these values.

[0049] The bottom of the outer liquid guide 212 is at a lower level than the bottom of the inner liquid guide 211. In this embodiment, the difference in horizontal height between the bottom of the inner liquid guide 211 and the bottom of the outer liquid guide 212 is 0.5 mm.

[0050] This embodiment of the application ensures that when the atomizing component 2 leaks, the atomizing liquid will flow downward along the inner wall of the support portion 11 by placing the bottom of the inner liquid guide 211 into the support portion 11. In addition, by setting the bottom of the outer liquid guide 212 to extend towards the air inlet portion 12 and the horizontal height to be lower than the horizontal height of the bottom of the inner liquid guide 211, the accurate installation of the atomizing component 2 can be ensured, and leakage caused by the sealing effect being affected due to the assembly being too high can be avoided.

[0051] Please see Figure 2 , Figure 3 , Figure 6As shown, in some embodiments, the supporting part 11 is provided with a limiting step 14 on the side near the atomizing component 2. The vertical projection of the limiting step 14 is located in the liquid storage tank 33, and the bottom of the inner liquid guiding component 211 is supported on the limiting step 14.

[0052] In this embodiment, the limiting step 14 is used to position and install the inner liquid guide 211, thereby improving the installation accuracy and efficiency of the inner liquid guide 211. At the same time, the position of the limiting step 14 is restricted to ensure that when the inner liquid guide 211 leaks, the atomizing liquid can be recovered by the liquid storage tank 33, thus preventing the atomizing liquid from leaking from the air inlet 31.

[0053] Furthermore, in this embodiment, the limiting step 14 forms a liquid guiding slope on the side facing the air inlet 31, and the liquid guiding slope is gradually inclined downward along the direction close to the air inlet 31.

[0054] In this embodiment, a guide slope is provided on the limiting step 14 to guide the flow of the atomized liquid in the opposite direction, ensuring that the atomized liquid can be recovered by the storage tank 33.

[0055] Please see Figure 5 As shown, in this embodiment, the sealing element 3 is provided with a lead wire hole 34 at the liquid storage tank 33, and the heating element 22 has a connecting wire 221. The connecting wire 221 extends through the lead wire hole 34 toward the air inlet 12, and the connecting wire 221 is interference-fitted with the lead wire hole 34.

[0056] In this embodiment, by providing a lead hole 34 at the liquid storage tank 33 that is interference-fitted with the connecting wire 221, the electrical connection to the heating element 22 is ensured while preventing leakage of the atomizing liquid along the connecting wire 221, thereby improving the leakage prevention performance of the atomizing core.

[0057] Please see Figures 1-3 As shown, in some embodiments, the atomizing core further includes a sleeve 4, which is mounted on the support portion 11 and fitted over the atomizing core.

[0058] Please see Figure 6 As shown, in some embodiments, the atomizing part 13 is provided with a first oil inlet hole 131, and the sleeve 4 is provided with a second oil inlet hole 41 on its side wall. The first oil inlet hole 131 and the second oil inlet hole 41 are staggered and at least partially overlap.

[0059] In this embodiment, a set angle is formed between the axis of the first oil inlet hole 131 and the axis of the second oil inlet hole 41, wherein the set angle is in the range of 30° to 45°; specifically, the angle formed between the axis of the first oil inlet hole 131 and the axis of the second oil inlet hole 41 can be set to any one of 30°, 35°, 40°, and 45° or a range between any two of these values.

[0060] By misaligning the first oil inlet 131 and the second oil inlet 41, this application ensures normal suction and effectively prevents oil leakage in a static state, thus improving the leak-proof performance of the atomizing core. At the same time, the misalignment of the first oil inlet 131 and the second oil inlet 41 within this range ensures normal suction and reduces the oil inlet speed, preventing a large amount of atomizing liquid from entering and causing oil leakage in the atomizing component 2.

[0061] Please see Figure 2 As shown, in this embodiment, the top of the external liquid guide 212 is tightly fitted to the inner wall of the ventilation end of the sleeve 4, so as to effectively reduce the negative pressure generated during the ventilation process, thereby avoiding the risk of leakage and improving the leakage prevention performance of the atomizing core.

[0062] Please see Figure 6 As shown, in this embodiment, a set distance d is formed between the inner wall of the sleeve 4 and the outer wall of the atomizing part 13, wherein the set distance d ranges from 0.3mm to 0.4mm; specifically, the set distance d can be set to any one of 0.3mm, 0.35mm, and 0.4mm or a range formed between any two of these values.

[0063] This embodiment of the application limits the set distance d between the inner wall of the sleeve 4 and the outer wall of the atomizing part 13, thereby reducing the liquid guiding speed without affecting normal suction, thus avoiding a large amount of atomizing liquid entering and causing oil leakage in the atomizing component 2.

[0064] Please see Figures 1-3 As shown, in some embodiments, the atomizing core further includes an electrical connection component 5, which is fitted onto the side of the air inlet 12 away from the support portion 11, and the electrical connection component 5 is connected to the connecting wire 221 of the heating element 22.

[0065] In this embodiment, the electrical connection assembly 5 includes a negative electrode ring 51, an insulating ring 52, and an electrode 53. The negative electrode ring 51 is mounted on the air intake 12, the insulating ring 52 is fitted onto the air intake 12 and fixes the negative electrode ring 51, and the electrode 53 passes through the negative electrode ring 51.

[0066] In this embodiment, the air inlet 12 is provided with at least one air supply hole 121, which is located between the support part 11 and the electrical connection assembly 5.

[0067] This application improves the overall structural tightness of the electrical connector by designing the structure of the air intake 12 and the electrical connector to avoid setting the air supply hole 121 and the air supply channel on the electrical connector.

[0068] In this embodiment, the atomizing core also includes several sealing rings 6, which are respectively fitted onto the atomizing core bracket 1 and the sleeve 4, so as to achieve waterproof and dustproof sealing when the atomizing core is installed on the electronic atomizing device.

[0069] Based on the atomizing core described above, this application embodiment also provides an electronic atomizing device, which includes an electronic atomizing device and a power supply device, wherein the electronic atomizing device is mounted on the power supply device.

[0070] The electronic atomizing device includes a housing and an atomizing core as described above. The atomizing core is installed inside the housing, and multiple sealing rings 6 are squeezed to achieve a waterproof and dustproof seal between the housing and the atomizing core, as well as a stable connection. The power supply device is electrically connected to the atomizing core and is used to supply power to the atomizing component 2 inside the atomizing core so as to heat the atomizing liquid to form an inhalable aerosol.

[0071] The electronic atomizing device provided in this application embodiment improves the leakage prevention performance of the atomizing core by using the atomizing core as described above, and forms a liquid storage tank 33 inside the atomizing core to facilitate the collection of leaked atomized liquid, thereby preventing the atomized liquid from leaking from the air inlet 31 and improving the user experience.

[0072] Obviously, the embodiments described above are only some embodiments of this application, not all embodiments.
