Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or it can be in a middle component. When a component is said to be "connected" to another component, it can be directly connected to the other component or it may be in a middle component.

[0020] Unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used in this invention includes any and all combinations of one or more of the associated listed items.

[0021] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0022] Please refer to Figures 1 to 3 This utility model provides an atomizing core 100, including a ceramic core 10 and a heating element 20, with the heating element 20 connected to the ceramic core 10. The ceramic core 10 is used to contact the oil in the oil storage chamber and guide the oil to permeate from one side to the other within the ceramic core 10. The heating element 20 is used to heat the oil permeating from the ceramic core 10 to atomize it.

[0023] The ceramic core 10 includes a main body 11 and a flange portion 12. The main body 11 includes a first surface 111 and a second surface 112 facing away from each other, and a side peripheral surface 113 connecting the first surface 111 and the second surface 112. The flange portion 12 is annular and disposed on the side peripheral surface 113. The first surface 111 is used to contact the oil in the oil storage chamber for oil intake, and the heating element 20 is disposed on the second surface 112, which is used for atomization.

[0024] The main body 11 can be roughly square, cuboid, or cube, without limitation. The flange 12 is roughly square-shaped and fits onto the main body 11. The main body 11 and flange 12 are integral structures formed by high-temperature firing of ceramic blanks. Optionally, both the main body 11 and flange 12 are porous ceramic bodies, allowing oil to permeate within themselves, thus accelerating the oil permeation rate. Alternatively, the main body 11 is a porous ceramic body, while the flange 12 is a dense ceramic body, allowing oil to permeate within the main body 11 but not within the flange 12. This allows for precise control of the oil permeation location, reducing the possibility of un-atomized oil residue in edge areas and improving oil utilization efficiency.

[0025] Most ceramic cores are currently cylindrical or square. When they are fitted with silicone parts (not shown), the silicone parts are fitted onto the side circumference of the ceramic core. The silicone parts are usually sealed to the ceramic core by extrusion. However, due to assembly tolerances and other reasons, gaps may be generated between the silicone parts and the ceramic core, resulting in poor sealing. Oil may leak from these gaps, causing oil leakage.

[0026] In this embodiment of the utility model, by providing a flange portion 12 on the side peripheral surface 113 of the main body 11, the silicone part can be sleeved on the flange portion 12 and tightly attached to the side peripheral surface 113 of the main body 11. The silicone part and the main body 11 are sealed by compression. Even if there is a gap between the silicone part and the main body 11 due to assembly tolerance, the silicone part can still ensure tight contact with the flange portion 12, which can prevent oil leakage due to gaps between the ceramic core 10 and the silicone part.

[0027] In addition, the flange 12 can also improve the structural strength of the main body 11 and reduce the risk of cracks or even damage to the main body 11.

[0028] Optional, see reference Figure 3 The first surface 111 has an oil inlet groove 114 recessed towards the second surface 112. The oil inlet groove 114 includes an inner peripheral wall corresponding to the side peripheral surface 113. Taking the main body 11 as a square as an example, the first surface 111 and the second surface 112 are mutually parallel planes. In the orthographic projection perpendicular to the first surface 111, the side peripheral surface 113 of the main body 11 is rectangular, so the inner peripheral wall of the oil inlet groove 114 is also rectangular, and the four sides of the rectangular side peripheral wall of the oil inlet groove 114 correspond one-to-one with and are parallel to the four sides of the rectangular side peripheral surface 113. The oil inlet groove 114 is used to communicate with the oil storage cavity. The oil in the oil storage cavity also flows into the oil inlet groove 114. The oil permeates inward from the bottom wall and side peripheral wall of the oil inlet groove 114 and is atomized at the second surface 112 under the heating action of the heating element 20.

[0029] Optional, see reference Figure 3 , Figure 5 and Figure 6 The oil inlet groove 114 is flared outwards from the bottom wall towards the opening. That is, the perimeter of the rectangular opening of the oil inlet groove 114 is the largest, gradually decreasing in size as the depth increases. Optionally, all four side walls of the inner peripheral wall of the oil inlet groove 114 are inclined relative to the first surface 111. Alternatively, at least one of the four side walls of the inner peripheral wall of the oil inlet groove 114 may be inclined relative to the first surface 111, while the remaining side walls may be perpendicular to the first surface 111. Thus, the flared shape of the oil inlet groove 114 facilitates the entry of oil from the oil storage chamber into the oil inlet groove 114.

[0030] In this embodiment, since the main body 11 has an oil inlet groove 114, the structure of the area near the edge of the first surface 111 of the main body 11 is relatively weak. However, by setting the flange 12, the structural strength of the weak part can be strengthened, reducing the risk of cracks and breakage.

[0031] In one embodiment, reference Figure 1 , Figure 2 and Figure 4The heating element 20 includes multiple heating units 21 and multiple embedded portions 22. Each heating unit 21 is annular, and multiple heating units 21 are connected in sequence. Each heating unit 21 is connected to at least one embedded portion 22, which extends into the interior of the main body 11.

[0032] The heating element 20 can be integrally formed with the ceramic core 10. The heating element 20 can be embedded into the ceramic blank when the ceramic core 10 is still in its ceramic blank state, and then the whole thing can be fired together. Of course, the heating element 20 can also be installed onto the ceramic core 10 after it has been made. There are no restrictions on the specific process.

[0033] Multiple heating units 21 can be located on the same plane. These units can be placed on the second surface 112, partially embedded in the main body 11, or completely embedded in the main body 11, without limitation. The multiple heating units 21 can extend in the same direction, for example, along the length of the main body 11. The ring shape of the heating unit 21 can be rectangular, rhomboid, elliptical, circular, etc. Adjacent heating units 21 can be connected by points; for example, if the heating unit 21 is rectangular or rhomboid, adjacent heating units 21 are connected through the sharp corners of the rectangle or rhombus. The heating unit 21 has a small cross-sectional dimension, such as width, thickness, or diameter, and functions as a heating wire. When electricity is applied, it generates high temperatures to atomize the oil.

[0034] The embedding part 22 is generally straight, and its length direction is perpendicular to the plane where the heating unit 21 is located. One end of the embedding part 22 is connected to the heating unit 21, and the other end is embedded in the main body 11. Optionally, a flange may be provided at the end of the embedding part 22 away from the heating unit 21, so that the embedding part 22 is generally "T" shaped, in order to enhance the connection and fixation effect between the embedding part 22 and the main body 11.

[0035] Optionally, the heating element 20 may further include a first connecting piece 23 and a second connecting piece 24. The first heating unit 21 of the plurality of heating units 21 is connected to the first connecting piece 23, and the last heating unit 21 is connected to the second connecting piece 24. The first connecting piece 23 and the second connecting piece 24 may also be coplanar with the plurality of heating units 21, and may also be provided with an embedded part 22, without limitation. The first connecting piece 23 is used to connect to the first wire, and the second connecting piece 24 is used to connect to the second wire. The first wire and the second wire are respectively used to connect to the positive and negative terminals of the battery of the electronic atomizer, so that the battery can supply power to the plurality of heating units 21 through the first wire, the second wire, the first connecting piece 23 and the second connecting piece 24, thereby realizing the heating and atomization function of the heating element 20 on the oil.

[0036] Optionally, the heating element 20 can be a one-piece structure, making the structure more stable. Alternatively, the heating element 20 can also be a separate structure.

[0037] The following is a detailed description of further improvements to the embodiments of this utility model.

[0038] Optional, see reference Figure 1 , Figure 4 and Figure 5 The side peripheral surface 113 of the main body 11 includes a first side surface 115 and a second side surface 116 facing away from each other; the flange portion 12 includes a first segment 121 and a second segment 122; the first segment 121 is disposed on the first side surface 115, and the second segment 122 is disposed on the second side surface 116. The first segment 121 protrudes from the first side surface 115 by a height of L1, and the second segment 122 protrudes from the second side surface 116 by a height of L2, satisfying: 0.8≤L2 / L1≤1.2.

[0039] The first side 115 and the second side 116 can both be planes, and can be perpendicular to the first surface 111 and the second surface 112 or have a certain angle of inclination, without restriction. The specific values ​​of L1 and L2 are not limited and can be set as needed. The value of L2 / L1 can be 0.8, 0.9, 1.0, 1.1, 1.2, etc. Satisfying 0.8≤L2 / L1≤1.2, so that the height of the first segment 121 protruding from the first side 115 is close to the height of the second segment 122 protruding from the second side 116, while achieving the structural strength of the main body 11 and a tight connection with the silicone parts, the specific ratio can be flexibly selected according to the specific structure of the electronic atomizer to improve adaptability.

[0040] Optional, see reference Figure 1 , Figure 4 and Figure 6 The side circumferential surface 113 of the main body 11 also includes a third side surface 117, which connects to the first side surface 115 and the second side surface 116. The flange portion 12 includes a third segment 123, which is disposed on the third side surface 117 and connects to the first segment 121 and the second segment 122. The third segment 123 protrudes from the third side surface 117 by a height L3, satisfying: 0.8≤L3 / L1≤1.2, 0.8≤L3 / L2≤1.2.

[0041] The third side 117 can be a plane, perpendicular to the first surface 111 and the second surface 112, or at a certain angle, without limitation. The specific value of L3 is not limited and can be set as needed. The values ​​of L3 / L1 and L3 / L2 can be 0.8, 0.9, 1.0, 1.1, 1.2, etc. The condition 0.8≤L3 / L1≤1.2 and 0.8≤L3 / L2≤1.2 is satisfied, making the height of the third segment 123 protruding from the third side 117 similar to the height of the first segment 121 protruding from the first side 115 and the height of the second segment 122 protruding from the second side 116. This ensures that the structural strength of the main body 11 is enhanced and that it is tightly connected to the silicone parts. The specific proportions can be flexibly selected according to the specific structure of the electronic atomizer to improve adaptability.

[0042] Optional, see reference Figure 1 , Figure 4 and Figure 6 The side circumferential surface 113 of the main body 11 also includes a fourth side surface 118, which connects to the first side surface 115 and the second side surface 116, and is opposite to the third side surface 117. The flange portion 12 also includes a fourth segment 124, which is disposed on the fourth side surface 118 and connects to the first segment 121 and the second segment 122. The fourth segment 124 protrudes from the fourth side surface 118 by a height L4, satisfying: 0.8≤L4 / L1≤1.2, 0.8≤L4 / L2≤1.2.

[0043] The fourth side 118 can be a plane, perpendicular to the first surface 111 and the second surface 112, or at a certain angle, without limitation. The specific value of L4 is not limited and can be set as needed. The values ​​of L4 / L1 and L4 / L2 can be 0.8, 0.9, 1.0, 1.1, 1.2, etc. The condition 0.8≤L4 / L1≤1.2 and 0.8≤L4 / L2≤1.2 is satisfied, making the height of the fourth segment 124 protruding from the fourth side 118 similar to the height of the first segment 121 protruding from the first side 115 and the height of the second segment 122 protruding from the second side 116. This ensures that the structural strength of the main body 11 is enhanced and that it is tightly connected to the silicone parts. The specific proportions can be flexibly selected according to the specific structure of the electronic atomizer to improve adaptability.

[0044] Optionally, L1, L2, L3, and L4 are equal, which makes it easy to make the width of the contact between the flange 12 and the silicone part (i.e., the dimension in the height direction of each protrusion on each side) equal, achieving a roughly the same sealing effect, reducing the risk of oil leakage, and at the same time, the strength enhancement effect of each position of the main body 11 is roughly the same, and the overall structure has no obvious weak areas, which can reduce the risk of damage to each position of the atomizing core 100.

[0045] Optional, see reference Figure 1 and Figure 4 Any two adjacent sides of the side circumferential surface 113 of the main body 11 can be smoothly transitioned, that is, any two adjacent sides from the first side 115 to the fourth side 118 can be smoothly transitioned. In this way, the main body 11 is less likely to be bumped and damaged during assembly.

[0046] Optional, see reference Figure 1 and Figure 4 Any two adjacent segments of the flange 12 can be smoothly transitioned. That is, any two adjacent segments from the first segment 121 to the fourth segment 124 can be smoothly transitioned, so that the flange 12 is less likely to be damaged during assembly.

[0047] Among them, any two adjacent sides from the first side 115 to the fourth side 118 form a rounded corner, and any two adjacent segments from the first segment 121 to the fourth segment 124 form a rounded corner. The rounded corners of the side circumferential surface 113 and the rounded corners of the flange portion 12 correspond one-to-one.

[0048] Optional, see reference Figure 1 , Figure 5 and Figure 6 The flange portion 12 includes a third surface 125 and a fourth surface 126 facing away from each other. The third surface 125 is flush with the first surface 111, and the fourth surface 126 is spaced apart from the second surface 112.

[0049] The third surface 125 and the fourth surface 126 can both be planar, parallel to the first surface 111 and the second surface 112, or they can be curved or not parallel; there are no restrictions. The fourth surface 126 is connected to the side peripheral surface 113 and spaced from the second surface 112, so that the height of the main body 11 is higher than the height of the flange 12, based on the flush first surface 111 and the third surface 125. This allows the heating element 20 to be spaced further away from the silicone part located at the flange 12, preventing deformation or odor from the silicone part due to high temperature. During assembly, the silicone part can be tightly fitted to the third surface 125 and the fourth surface 126 to improve the sealing effect between the silicone part and the ceramic core 10.

[0050] Furthermore, it facilitates the manufacture of the main body 11 and flange 12, reducing the complex process issues caused by the complex structure. At the same time, when the ceramic core 10 is assembled to form an electronic atomizer, the flush first surface 111 and third surface 125 are more likely to be tightly connected with the silicone part. When the silicone part is squeezed, it is also easier to keep it in close contact with each section of the flange 12. When the silicone part is squeezed on the third surface 125, it will not be blocked by the side peripheral surface 113 and deformed. If the third surface 125 is connected to the side peripheral surface 113 but has a gap with the first surface 111, some areas of the silicone part may be too close to the side peripheral surface 113 and deformed during compression, while other areas may be subjected to less or no compression, which will affect the sealing effect.

[0051] Optionally, the distance between the first surface 111 and the second surface 112 is H1, and the distance between the third surface 125 and the fourth surface 126 is H2, satisfying: 0.1≤H2 / H1≤0.5.

[0052] The value of H2 / H1 can be 0.1, 0.2, 0.3, 0.4, 0.5, etc., without restriction. Satisfying 0.1≤H2 / H1≤0.5 ensures that the height dimension (H2) of the flange 12 is moderate. It is neither too small, which would make it easy to damage, and it can meet the function of serving as the base for assembling silicone parts and can play a role in strengthening the structure of the main body 11. It is also not too large, which would make it difficult to assemble silicone parts and avoid the silicone parts being too close to the heating element 20, which would cause high temperature deformation of the silicone parts or produce odor. It can also reduce the space occupied and facilitate the miniaturization of electronic atomizers.

[0053] Based on the atomizing core 100 of the above-described embodiments of the present invention, the present invention also provides an electronic atomizer, including the atomizing core 100 of any of the foregoing embodiments.

[0054] The electronic atomizer of this embodiment employs a special atomizing core 100 structure. The atomizing core 100 has a flange 12 provided on the side circumferential surface 113 of the main body 11. A silicone component can be fitted onto the flange 12 and tightly adhered to the side circumferential surface 113 of the main body 11. The silicone component and the main body 11 are sealed by compression. Even if there are gaps between the silicone component and the main body 11 due to assembly tolerances, the silicone component still ensures tight contact with the flange 12, preventing oil leakage due to gaps between the ceramic core 10 and the silicone component. Furthermore, the atomizing core 100 has good structural strength and is not easily damaged.
