[0036] The electronic atomizer provided by this utility model adopts a liquid storage chamber and an atomizing component 1000 in the embodiment of this utility model. The liquid storage chamber is connected to the outer surface of the atomizing core 200. The liquid storage chamber is used to contain oil, thereby realizing the atomization of the oil. At the same time, the atomizing component 1000 has a large heating area and uniform heating.

[0037] Please refer to Figure 1 and Figure 2This utility model provides an atomizing component 1000 for use in an electronic atomizer. The atomizing component 1000 includes an atomizing core 200 and a heating structure 100. The atomizing core 200 has a through hole 201. The heating structure 100 includes a plurality of heating elements 10, which are spaced apart from each other on the atomizing core 200 and are all adjacent to the inner wall of the through hole 201. The outer surface of the atomizing core 200 is used to receive oil, and the atomizing core 200 is used to transfer oil from the outer surface of the atomizing core 200 to the inner wall of the through hole 201. The heating elements 10 are used to generate heat to atomize the oil at the inner wall of the through hole 201.

[0038] Optionally, the atomizing core 200 has a porous structure. After the oil enters the atomizing core 200 from its outer surface, it disperses into smaller droplets. When these droplets approach the inner wall of the through-hole 201, they are heated and evaporated by the heating element 10, forming even smaller aerogel particles. For example, the atomizing core 200 is a ceramic atomizing core 200. Optionally, the heating structure 100 can be made of a material that meets structural strength, high temperature resistance, and ease of processing, specifically such as iron-chromium-aluminum alloy, nickel-chromium alloy, nickel, titanium, and stainless steel, without limitation.

[0039] Optionally, the shapes of the multiple heating elements 10 correspond to the shape of the inner wall surface of the through hole 201. Specifically, in one embodiment, a portion of the inner wall surface of the through hole 201 where the heating elements 10 are located is curved, and the multiple heating elements 10 extend and bend to match the curvature of the inner wall surface of the through hole 201. In another embodiment, a portion of the inner wall surface of the through hole 201 where the heating elements 10 are located is flat, and the multiple heating elements 10 are flat. Optionally, the heating elements 10 and the atomizing core 200 can be an integral structure, or they can be detachably connected by means of snap-fit, screw-fit, or riveting, without limitation.

[0040] By configuring the atomizing assembly 1000, which includes an atomizing core 200 and a heating structure, the atomizing core 200 has a through hole 201. The heating structure 100 includes multiple heating elements 10, which are spaced apart on the atomizing core 200 and adjacent to the inner wall of the through hole 201. The outer surface of the atomizing core 200 is used to receive oil, and the atomizing core 200 is used to transfer oil from the outer surface of the atomizing core 200 to the inner wall of the through hole 201. The heating elements 10 are used to generate heat so that the oil is atomized at the inner wall of the through hole 201. This allows the oil to penetrate through the outer surface of the atomizing core 200 to the inner wall of the through hole 201 and be atomized by the multiple heating elements 10, thereby improving the heating area and heating uniformity of the atomizing assembly 1000.

[0041] Please refer to Figure 1 and Figure 2 The through hole 201 extends along the first direction Z. In the orthographic projection of the first direction Z, the outer contour of the atomizing core 200 is circular, and the contour of the through hole 201 is rectangular.

[0042] Optionally, the atomizing core 200 can be a cylindrical component, a spherical component, or an elliptical component, etc., without limitation. Optionally, the outline shape of the through hole 201 in the orthographic projection of the first direction Z can be a square, a rectangle, or a hexagon, an octagon, a triangle, an ellipse, or a circle, etc., without limitation. Optionally, multiple heating elements 10 extend along the first direction Z to increase the heating area of ​​the inner wall of the through hole 201. Optionally, the atomizing core 200 can be provided with multiple heating elements 10 in the first direction Z. Optionally, when the inner wall surface of the through hole 201 is composed of multiple planes, the heating element 10 can be set as a flat plate structure to facilitate the assembly and processing of the heating element 10.

[0043] In one specific embodiment, the atomizing core 200 is a cylindrical component, and the through hole 201 has a rectangular outline in the orthographic projection of the first direction Z. The atomizing core 200 includes an outer peripheral surface 202, a first end face 203 and a second end face 204 facing away from each other in the first direction Z, and the through hole 201 penetrates the first end face 203 and the second end face 204. In the orthographic projection of the first direction Z, the center point of the through hole 201 coincides with the center point of the atomizing core 200. At least one of the first end face 203, the second end face 204, and the outer peripheral surface 202 is used to communicate with a liquid storage tank to receive oil.

[0044] By setting the through hole 201 to extend along the first direction Z, the outer contour shape of the atomizing core 200 is circular in the orthogonal projection of the first direction Z. This allows the shape of the atomizing core 200 to be adapted to the cylindrical structure of the electronic atomizer, thereby increasing the effective atomization area of ​​the atomizing core 200 and reducing the assembly and processing difficulty of the atomizing core 200. At the same time, setting the contour shape of the through hole 201 to be rectangular allows the heating element 10 to be set as a flat structure, which facilitates the assembly and processing of the heating element 10 and is beneficial to improving the heating area and heating uniformity of the atomizing assembly 1000.

[0045] Please refer to Figure 1 and Figure 2 All heating elements 10 are embedded in the atomizing core 200, or the atomizing core 200 has an installation groove 205 on the inner wall of the through hole 201, and all heating elements 10 are at least partially housed in the installation groove 205, or all heating elements 10 are connected to the inner wall of the through hole 201.

[0046] In one specific embodiment, the atomizing core 200 has an installation groove 205 formed on the inner wall surface of the through hole 201. Multiple heating elements 10 are housed within the installation groove 205, and the multiple heating elements 10 are flush with the inner wall surface of the through hole 201. This results in a high connection strength between the multiple heating elements 10 and the atomizing core 200, making them less prone to detachment due to external impacts and material degradation / aging. Simultaneously, it improves the movement path of the oil within the atomizing core 200, thereby enhancing the oil dispersion effect and resulting in better atomization performance from the heating elements 10. Optionally, the heating elements 10 can be connected and fixed to the atomizing core 200 by snap-fit, screw-fit, or riveting, or they can be connected and fixed to the atomizing core 200 by an integral molding process; there are no limitations.

[0047] In another specific embodiment, all of the multiple heating elements 10 are embedded within the atomizing core 200, resulting in a high connection strength between the multiple heating elements 10 and the atomizing core 200, making them less prone to detachment due to external impacts and material degradation and aging. Optionally, the heating elements 10 and the atomizing core 200 can be connected and fixed through an integrated molding process such as co-sintering, 3D printing, or ceramic fiber composite process, without limitation.

[0048] In another specific embodiment, multiple heating elements 10 are connected to the inner wall surface of the through hole 201, which reduces the assembly difficulty and process requirements of the heating elements 10 and the atomizing core 200, and is beneficial to reducing production and maintenance costs. Optionally, the heating elements 10 can be connected and fixed to the atomizing core 200 by snap-fitting, screwing, riveting, welding, or by directly printing conductive paste containing metal particles (such as platinum or nickel-chromium alloy) onto the inner wall surface of the through hole 201 through a thick film printing process to form a preset heating circuit pattern, and then sintering at high temperature to form the heating elements 10 and achieve a firm bond between the heating elements 10 and the atomizing core 200, without limitation.

[0049] Please refer to Figure 1 and Figure 2 The through hole 201 extends along the first direction Z. The inner wall of the through hole 201 includes a first side wall 206 and a second side wall 207 that are opposite each other in the second direction Y. Both the first side wall 206 and the second side wall 207 are provided with heating elements 10. The second direction Y intersects with the first direction Z.

[0050] In one specific embodiment, the outline shape of the through hole 201 in the orthographic projection of the first direction Z is rectangular. Therefore, the through hole 201 has a first sidewall 206 and a second sidewall 207 opposite to each other in the second direction Y. Optionally, the length direction of the first sidewall 206 and the second sidewall 207 is both the first direction Z. A heating element 10 can be provided on both the first sidewall 206 and the second sidewall 207, or multiple heating elements 10 can be provided sequentially along the first direction Z, without limitation.

[0051] Optionally, when the outline shape of the through hole 201 in the orthographic projection of the first direction Z is a polygon with more than 4 sides and an odd number of sides, the first sidewall 206 and the second sidewall 207 can be any two non-adjacent surfaces without restriction. Optionally, when the outline shape of the through hole 201 in the orthographic projection of the first direction Z is a polygon with more than 4 sides and an even number of sides, the first sidewall 206 and the second sidewall 207 can be any two surfaces facing each other without restriction.

[0052] By setting a through hole 201 extending along the first direction Z, the inner wall of the through hole 201 includes a first side wall 206 and a second side wall 207 opposite to each other in the second direction Y. Both the first side wall 206 and the second side wall 207 are provided with heating elements 10. The second direction Y intersects with the first direction Z, so that when the oil moves from the outer surface of the through hole 201 to the inner wall surface near the through hole 201, it can be heated and atomized by the heating elements 10 on the opposite first side wall 206 and the second side wall 207. This prevents the oil at the connection of different side walls from being heated by the heating elements 10 on different side walls at the same time, which would cause scorching. This is beneficial to improving the heating area and heating uniformity of the atomizing component 1000.

[0053] Please refer to Figure 1 and Figure 2 The through hole 201 also includes a third sidewall 208 and a fourth sidewall 209 opposite each other in the third direction X. Both the third sidewall 208 and the fourth sidewall 209 are provided with heating elements 10. The third direction X intersects with the first direction Z and the second direction Y.

[0054] In one specific embodiment, the through hole 201 has a rectangular outline in the orthographic projection of the first direction Z. Therefore, the through hole 201 has a first sidewall 206 and a second sidewall 207 opposite to each other in the second direction Y, and a third sidewall 208 and a fourth sidewall 209 opposite to each other in the third direction X. The third sidewall 208 and the fourth sidewall 209 are both connected to the first sidewall 206 and the second sidewall 207. Optionally, the length direction of the third sidewall 208 and the fourth sidewall 209 is both in the first direction Z. Each of the third sidewall 208 and the fourth sidewall 209 can be provided with a heating element 10, or multiple heating elements 10 can be provided sequentially along the first direction Z, without limitation. Optionally, the heating elements 10 on any two adjacent inner wall surfaces have a spacing distance in the second direction Y and / or the third direction X, so as to reduce the phenomenon of oil at the connection of different inner wall surfaces being heated by heating elements 10 on different inner wall surfaces at the same time, which is beneficial to improving the heating area and heating uniformity of the atomizing component 1000.

[0055] Optionally, when the outline shape of the through hole 201 in the orthographic projection of the first direction Z is a polygon with more than 4 sides and an odd number of sides, the first sidewall 206, the second sidewall 207, the third sidewall 208, and the fourth sidewall 209 can be any one of the inner wall surfaces, without restriction. Optionally, the heating elements 10 on any two adjacent inner wall surfaces have a spacing distance in the second direction Y and / or the third direction X, so as to reduce the phenomenon of oil at the connection of different inner wall surfaces being heated by the heating elements 10 on different inner wall surfaces at the same time, which would cause scorching. This is beneficial to improving the heating area and heating uniformity of the atomizing assembly 1000.

[0056] Optionally, when the outline shape of the through hole 201 in the orthographic projection of the first direction Z is a polygon with more than 4 sides and an even number of sides, the first sidewall 206 and the second sidewall 207 can be any two surfaces facing each other, and the third sidewall 208 and the fourth sidewall 209 can be any other two surfaces facing each other. The first sidewall 206, the second sidewall 207, the third sidewall 208, and the fourth sidewall 209 are all spaced apart to reduce the phenomenon of oil at the connection of different inner wall surfaces being heated by the heating element 10 on different inner wall surfaces at the same time, which is beneficial to improving the heating area and heating uniformity of the atomizing component 1000.

[0057] The through hole 201 also includes a third sidewall 208 and a fourth sidewall 209 opposite each other in the third direction X. Both the third sidewall 208 and the fourth sidewall 209 are provided with heating elements 10. The third direction X intersects with the first direction Z and the second direction Y, which further increases the heating area of ​​the atomizing component 1000 and further improves the heating uniformity of the atomizing component 1000.

The positive electrode post 21 and the negative electrode post 31 are also spaced apart in the second direction Y or the third direction X. The positive electrode connector 20 and the negative electrode connector 30 are both located on the outer side of the through hole 201 to prevent the positive electrode connector 20 and the negative electrode connector 30 from obstructing the gas flow of the through hole 201.

[0062] Optionally, the connection method between the positive electrode connector 20 and the negative electrode connector 30 and the atomizing core 200 is similar to the connection method between the heating element 10 and the atomizing core 200, which can be referred to for reference only and will not be described in detail. Optionally, the positive electrode connector 20, the negative electrode connector 30 and the multiple heating structures 100 can be an integral structure, or they can be detachably connected by means of snap-fit, screw-fit and riveting, etc., without restriction.

A positive electrode connector 20 is connected to the same end of both heating elements 10, and a negative electrode connector 30 is connected to the end of both heating elements 10 away from the positive electrode connector 20, so that the two heating elements 10 are connected in parallel. In other embodiments, the number of heating elements 10 can also be any positive integer greater than 2, and the parallel connection method is similar to the aforementioned embodiments, which can be referred to for further details.

[0064] By setting a positive electrode connector 20 and a negative electrode connector 30, the positive electrode connector 20 is connected to the same end of multiple heating elements 10, and the negative electrode connector 30 is connected to the end of multiple heating elements 10 away from the positive electrode connector 20, so that multiple heating elements 10 can be connected in parallel through the positive electrode connector 20 and the negative electrode connector 30, while improving the structural stability of the heating structure 100.

[0065] Please refer to Figure 2 and Figure 3 The heating element 10 includes multiple heating units 11 connected in series, and the heating unit 11 is a ring structure connected end to end.

[0066] Optionally, the through hole 201 extends along the first direction Z, and multiple heating units 11 of a heating element 10 are connected in series along the first direction Z.

[0067] Optionally, each of the multiple heating elements 10 may include multiple heating units 11, or only one or a few heating elements 10 may include multiple heating units 11, without limitation.

[0070] Optionally, in order to increase the number of heating units 11 on each heating element 10 and reduce the contact area between adjacent heating units 11, the outer contour shape and inner contour shape of each heating unit 11 in the through direction of its structural hole 111 are both spindle-shaped. Optionally, the outer contour shape and inner contour shape of each heating unit 11 in the through direction of its structural hole 111 can also be triangular, circular, elliptical, etc., without limitation.

[0071] By setting the heating element 10 to include multiple heating units 11 connected in series, and the heating unit 11 is a ring structure connected end to end, the heating area of ​​the heating element 10 is large.
