[0002] At present, ceramic materials have gradually become an ideal choice for heating elements due to their excellent high temperature resistance, corrosion resistance, and electrical insulation properties. The metal heating part is embedded in the ceramic material, and an atomization hole is set in the ceramic material. The heating part is heated by powering on, and then the liquid flowing through the inner wall of the atomization hole is atomized through the microporous structure on the ceramic surface. However, the existing ceramic heating atomizer has only a single hole, a small atomization area, and is prone to hole clogging and burning (core sticking), and the atomized gas is difficult to evaporate and discharge quickly. When it is used in electronic cigarettes, it is difficult to restore the taste of the smoke oil.

[0026] 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.

[0027] 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.

[0028] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0029] In an embodiment of the present invention, a double-hole ceramic heating element 100 is provided, which is used to generate heat when powered on, thereby atomizing liquid such as tobacco oil at high temperature, and then generating gases such as smoke.

[0030] Combination Figure 1-Figure 6 As shown, the double-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 .

[0031] Wherein, the ceramic part 10 is made of ceramic material. Figure 1 or Figure 2 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. In this embodiment, the ceramic part 10 is roughly in a runway shape (flat shape), that is, the cross-section of the ceramic part 10 is elliptical or oblong (semicircular on both sides and rectangular in the middle), thereby reducing the overall front and rear space requirements of the product (such as an electronic cigarette) and making the product thinner.

[0032] The ceramic part 10 is provided with two atomization holes 101 spaced apart from each other. The two atomization holes 101 can be symmetrically arranged on the left and right sides of the central axis of the ceramic part 10, that is, the central axis of the atomization hole 101 is parallel to the central axis of the ceramic part 10. The atomization hole 101 is one of a circular hole, a regular polygonal hole, and an irregular hole. For example, Figure 1 and Figure 5 As shown, the cross section of the atomization hole 101 is circular; Figure 2 and Figure 6 As shown, the cross section of the atomizing hole 101 is arc-shaped on one side and square-shaped on the other side. Of course, the shape of the atomizing hole 101 is not limited to the two shown in the exemplary drawings, and other shapes are also within the protection scope of the present invention.

[0033] Specifically, the inner wall surface of the atomization 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 smoke and other gases, and then evaporate and discharge from the atomization hole 101 to the outside. Since the two atomization holes 101 are arranged at intervals, a convection loop can be formed and the convection area can be increased, so that the convection dead corners can be effectively eliminated, the air convection is enhanced, and the discharge of gases such as smoke is promoted. In addition, compared with a single hole, the two atomization holes 101 directly increase the atomization area, thereby improving the atomization efficiency, and can also effectively reduce the occurrence of hole blockage. If one atomization hole 101 is blocked, the other atomization hole 101 can be used, which reduces the probability of failure.

[0034] In an embodiment of the present invention, the heating part 20 is embedded in the ceramic part 10 and is arranged around the two atomization holes 101. The heating part 20 is made of nickel-chromium wire, nickel-chromium mesh, or nickel-chromium sheet, which 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 scope of protection of the present invention.

[0035] 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 atomization hole 101. Furthermore, the number of the coils can be multiple, which are arranged at intervals up and down along the ceramic part 10, so that the ceramic part 10 heats more evenly and the cost is lower.

[0036] In another embodiment, 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 e-liquid. 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 burning), so that the taste of the e-liquid can be better restored.

[0037] In an exemplary embodiment, Figure 4 and Figure 6As shown, the heating part 20 passes around the periphery of the first atomization hole 101 and then passes around the periphery of the second atomization hole 101 in the same direction. That is, the heating part 20 is embedded in the ceramic part 10 in an "O" shape, so that the ceramic part 10 is heated more evenly. At this time, the heating part 20 does not pass between the two atomization holes 101.

[0038] In another exemplary embodiment, Figure 3 and Figure 5 As shown, the heating part 20 bypasses the periphery of the first atomization hole 101, passes through the area between the two atomization holes 101, and then reversely bypasses the periphery of the second atomization hole 101. That is, the heating part 20 is embedded in the ceramic part 10 in an "S" shape. Compared with the traditional heating wire structure and the above-mentioned embodiment, the circumferential length of the heating part 20 around the atomization hole 101 is longer, which increases the contact area of ​​the heating part 20 in the ceramic part 10, and further makes the ceramic part 10 heat more evenly, avoiding the situation of local burning.

[0039] It should be noted that when the heating portion 20 surrounds the atomization hole 101, its cross section does not form a 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.

[0040] 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.

[0041] The present invention further provides an electronic cigarette, comprising the double-hole ceramic heating element 100 as described in any one of the above embodiments.

[0042] In summary, the double-hole ceramic heating element 100 and the electronic cigarette provided by the present invention, by setting two atomization holes 101 in the ceramic part 10, increase the atomization area, increase the smoke volume, and are less likely to be blocked (one atomization hole 101 is blocked and the other atomization hole 101 is still available), and at the same time, the air convection in the hole can be enhanced between the two atomization holes 101, so that the smoke gas in the atomization hole 101 can be quickly volatilized and discharged. In addition, the heating part 20 is set around the two atomization holes 101, so that the two atomization holes 101 can be evenly heated, completely atomized and not easy to burn, and can better restore the taste of the smoke oil when used in electronic cigarettes.

[0043] 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.
