[0034] In order to make the purpose, technical solution and beneficial technical effect of the present invention clearer, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described in this specification are only for explaining the present invention, not for limiting the present invention.

[0035] It should also be understood that the terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0036] It should be further understood that the term "and / or" used in the present description and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0037] In an embodiment of the present invention, a spiral hole ceramic heating element 100 is provided, which is used to generate heat when powered on, so as to atomize liquid such as tobacco oil at high temperature, thereby generating gas such as smoke. When inhaled, spiral smoke can be formed, reducing the dead angle of gas flow, and finally making the smoke larger and fuller, so as to better restore the taste of tobacco oil.

[0038] like Figure 1-Figure 4 As shown, the spiral hole ceramic heating element 100 includes: a ceramic portion 10 , a heating portion 20 , and a positive electrode terminal 31 and a negative electrode terminal 32 .

[0039] Wherein, the ceramic part 10 is made of ceramic material. Figure 1-Figure 4 As shown, the ceramic part 10 is in a columnar shape, such as a cylindrical shape, a prism shape, or other columnar shapes with irregular cross-sections. Figure 1 and Figure 2 For example, a rectangular parallelepiped, such as Figure 3 and Figure 4 An exemplary cylindrical shape is shown.

[0040] The ceramic part 10 is provided with a spiral hole 101 for atomization. Furthermore, the central axis of the spiral hole 101 is in the same straight line as the central axis of the ceramic part 10. The spiral hole 101 is one of a circular hole, a regular polygonal hole, and an irregular hole. Preferably, the spiral hole 101 is a cylindrical hole. The inner wall surface of the spiral hole 101 is the rough surface of the ceramic part 10. When the liquid such as the smoke oil is heated on its surface, it will be atomized to form a gas such as smoke, and then evaporate from the spiral hole 101 to the outside.

[0041] In an embodiment of the present invention, Figure 7-Figure 9 As shown, the heating part 20 is embedded in the ceramic part 10 and arranged around the spiral hole 101. The heating part 20 is a nickel-chromium wire (such as Figure 8 as shown), or nickel-chromium mesh (as Fig. 9 As shown), or nickel-chromium sheet (as Figure 7 As shown), it has high heating efficiency, good thermal conductivity and long service life. Of course, the heating part 20 can also be made of other materials that can generate heat through electricity, all of which are within the protection scope of the present invention.

[0042] In one embodiment, the heating part 20 is a coil, which is embedded in the middle of the ceramic part 10 along the length direction of the threaded hole 101. Furthermore, the number of the coils can be multiple, which are arranged at intervals along the upper and lower sides of the ceramic part 10, so that the ceramic part 10 heats more evenly and the cost is lower. Figure 8 As shown, the middle portion of the heating wire can also be wound in a spiral shape to increase the contact area embedded in the ceramic body 10 .

[0043] In another embodiment, Fig. 9As shown, the heating part 20 is a mesh. Compared with the coil, the mesh has a higher heating efficiency and can quickly heat up, thereby improving the atomization efficiency of liquids such as smoke oil. At the same time, the mesh can cover more parts of the ceramic part 10, so that the heating of the ceramic part 10 is more uniform, the atomization is more complete, and it is not easy to burn (also called core sticking), so that the taste of the smoke oil can be better restored. Among them, the heating part 20 is embedded in the ceramic part 10 in an "O" shape, and surrounds the circumference of the spiral hole, so that the heating of the ceramic part 10 is more uniform.

[0044] It should be noted that when the heating portion 20 surrounds the spiral hole 101, its cross section does not form a closed ring loop, but has two end points, and these two end points are the connection points of the positive and negative poles of the power supply.

[0045] In addition, the heating part, no matter it is a heating wire, a heating net or a heating sheet, can be combined with the above-mentioned ceramic parts 10 of different shapes respectively, so as to obtain different combination structures of ceramic parts of various shapes and heating parts of various shapes, which are all within the protection scope of the present invention.

[0046] In the embodiment of the present invention, one end of the positive terminal 31 and one end of the negative terminal 32 are both fixed to the ceramic part 10, and are respectively electrically connected to the preset positions of the heating part 20 (i.e., the two end points in the above cross section), so as to supply power to the heating part 20. The positive terminal 31 and the negative terminal 32 are respectively used to connect the positive and negative electrodes of the external power supply.

[0047] In the embodiment of the present invention, the inner wall of the spiral hole 101 is provided with a threaded portion 102 . The threaded portion 102 has a convex or concave shape relative to the inner wall surface of the spiral hole 101 .

[0048] In the first embodiment, if Figure 1 , Figure 2 , Figure 5 As shown, the threaded portion 102 is a spiral strip groove, wherein the cross section of the strip groove is rectangular, semicircular, or trapezoidal, and of course, the cross section can also be other irregular shapes.

[0049] In the second embodiment, if Figure 3 , Figure 4 , Figure 6 As shown, the threaded portion 102 is a spiral strip-shaped protrusion, wherein the cross section of the strip-shaped protrusion is one of a rectangle, a semicircle, and a trapezoid. Of course, the cross section can also be other irregular shapes.

[0050] Therefore, by providing the inner wall of the spiral hole 101 with a concave or convex threaded portion 102, the area inside the spiral hole 101 is increased, and spiral smoke can be formed during inhalation. At the same time, the condensed liquid formed when the smoke condenses will be blocked by the threaded portion 102. The slope of the threaded portion 102 makes it more difficult for the condensed liquid to flow downward, thereby reducing the possibility of leakage. When the heating portion 20 is heated, the condensed liquid can be atomized again.

[0051] The present invention further provides an electronic cigarette, comprising the spiral hole ceramic heating element 100 as described in any one of the above embodiments.

[0052] In summary, the spiral hole ceramic heating element 100 and the electronic cigarette provided by the present invention have the following beneficial effects:

[0053] (1) By providing a threaded portion 102 on the inner wall of the spiral hole 101, the atomization area and the heating area are increased compared to the conventional smooth inner wall, and a larger amount of e-liquid can be atomized;

[0054] (2) By providing the threaded portion 102, the smoke flowing through the spiral hole 101 can form spiral smoke during inhalation, thereby enhancing air convection, thereby increasing the amount of smoke, making the smoke fuller, and restoring the flavor more completely;

[0055] (3) The threaded portion 102 can contain or block the condensed liquid, which prevents it from flowing downward, thereby reducing oil leakage. At the same time, the smoke oil condensed on the threaded portion 102 can also be atomized and reused;

[0056] (4) By embedding the heating part 20 in the ceramic part 10, the ceramic part 10 can heat more evenly, so that the smoke oil can be atomized more completely and is not easy to burn or stick to the core.

[0057] The present invention is not limited to what is described in the specification and implementation modes, and therefore additional advantages and modifications can be easily realized by those skilled in the art. Therefore, without departing from the spirit and scope of the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details, representative devices, and illustrative examples shown and described herein.
