[0026] In order to make the purpose, technical scheme and beneficial technical effects of the utility model clearer and more understandable, the utility model will be further described in detail below in combination with the drawings and specific embodiments. It should be understood that the specific embodiments described in the specification are only for the purpose of explaining the utility model and are not intended to limit the utility model.

[0027] It should also be understood that the terms used in this utility model specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model. As used in the utility model specification and the appended claims, the singular forms "a", "an" and "the" are intended to include the plural forms unless the context clearly indicates otherwise.

[0028] It should be further understood that the term "and / or" used in the utility model specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes these combinations.

[0029] In the embodiments of the utility model, a double-hole ceramic heating body 100 is provided for heating when powered on, thereby atomizing liquid such as tobacco tar at high temperature, and further generating gas such as smoke.

[0030] As shown in Figures 1-6 The double-hole ceramic heating body 100 includes a ceramic part 10, a heating part 20, and a positive electrode terminal 31 and a negative electrode terminal 32.

[0031] The ceramic part 10 is made of ceramic material. Further, as shown in Figure 1 Or Figure 2 The ceramic part 10 is columnar, such as cylindrical, prismatic or other columnar with irregular cross-section. In the present embodiment, the ceramic part 10 is generally racetrack-shaped (flat), i.e., the cross-section of the ceramic part 10 is elliptical or oblong (both sides are semicircular and the middle is rectangular), so as to reduce the front and back space requirements of the product (such as an electronic cigarette) as a whole, making the product thinner.

[0032] The ceramic part 10 is provided with two atomizing holes 101 arranged at intervals, which 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 atomizing hole 101 is parallel to the central axis of the ceramic part 10. Among them, the atomizing hole 101 is one of a circular hole, a regular polygon hole and an irregular hole. For example, as shown in Figure 1 As shown in Figure 5 , the cross section of the atomizing hole 101 is circular; as shown in Figure 2 As shown in Figure 6 , the cross section of the atomizing hole 101 is arc-shaped on one side and square 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 application.

[0033] Specifically, the inner wall surface of the atomizing hole 101 is the rough surface of the ceramic part 10, and when the liquid such as tobacco tar is heated on its surface, it will be atomized to form smoke and other gases, and then volatilize and discharge outward from the atomizing hole 101. Since the two atomizing holes 101 are arranged at intervals, a convection loop can be formed and the convection area can be increased, so that the convection dead angle can be effectively eliminated, the air convection can be enhanced, and the smoke and other gas discharge can be promoted. In addition, compared with a single hole, the atomizing area is directly increased, so that the atomizing efficiency can be improved, and the occurrence of hole blockage can be effectively reduced. If one atomizing hole 101 is blocked, the other atomizing hole 101 can still be used, reducing the probability of failure.

[0034] In an embodiment of the present application, the heating part 20 is embedded in the ceramic part 10 and surrounds the two atomizing holes 101. The material of the heating part 20 is nickel-chromium wire, or nickel-chromium mesh, or nickel-chromium sheet, which has high heating efficiency, good heat conduction performance and long service life. Of course, the heating part 20 can also be other materials that can be electrified to heat, which are all within the protection scope of the present application.

[0035] In one embodiment, the heating part 20 is a coil embedded in the ceramic part 10 at a middle position along the length direction of the atomizing hole 101. Further, the number of the coil can be multiple, which are arranged at intervals up and down along the ceramic part 10, so that the ceramic part 10 heats more uniformly, and the cost is lower.

[0036] In another embodiment, the heating part 20 is a mesh. Compared with the coil, the mesh has higher heating efficiency and can quickly heat up, thereby improving the atomizing efficiency of the liquid such as tobacco tar. At the same time, the mesh can cover more parts in the ceramic part 10, so that the ceramic part 10 heats more uniformly, the atomization is more complete, and it is not easy to burn (also called burnt core), thereby better restoring the taste of tobacco tar.

[0037] In one exemplary embodiment, as shown in Figure 4 As shown in Figure 6As shown, the heating portion 20 passes around the periphery of the first atomization hole 101 and then passes between the two atomization holes 101, and then reversely passes around the periphery of the second atomization hole 101. That is, the heating portion 20 is embedded in the ceramic portion 10 in an "S" shape. Compared with the conventional heating wire structure and the above-mentioned embodiments, the heating portion 20 has a longer circumferential length around the atomization hole 101, increases the contact area of the heating portion 20 in the ceramic portion 10, and further makes the ceramic portion 10 heat more uniformly, avoiding local burning.

[0038] In another exemplary embodiment, as shown in FIG. 4, the heating portion 20 passes around the periphery of the first atomization hole 101 and then reversely passes between the two atomization holes 101, and then reversely passes around the periphery of the second atomization hole 101. That is, the heating portion 20 is embedded in the ceramic portion 10 in a "Z" shape. Figure 3 With Figure 5 As shown, the heating portion 20 passes around the periphery of the first atomization hole 101 and then passes between the two atomization holes 101, and then reversely passes around the periphery of the second atomization hole 101. That is, the heating portion 20 is embedded in the ceramic portion 10 in an "S" shape. Compared with the conventional heating wire structure and the above-mentioned embodiments, the heating portion 20 has a longer circumferential length around the atomization hole 101, increases the contact area of the heating portion 20 in the ceramic portion 10, and further makes the ceramic portion 10 heat more uniformly, avoiding local burning.

[0039] It should be noted that when the heating portion 20 passes around the atomization hole 101, the cross section does not form a ring loop, but has two end points, which are the connection points of the positive and negative electrodes of the power supply.

[0040] In the embodiment of the present application, one end of the positive terminal 31 and one end of the negative terminal 32 are both fixed to the ceramic portion 10 and are respectively electrically connected to the preset positions (i.e. the two end points in the cross section) of the heating portion 20, thereby supplying power to the heating portion 20. The positive terminal 31 and the negative terminal 32 are respectively used for connecting the positive and negative electrodes of the external power supply.

[0041] The utility model also provides an electronic cigarette, including the double hole ceramic heating body 100 of any one of the above-mentioned embodiments.

[0042] In summary, the double hole ceramic heating body 100 and the electronic cigarette provided by the present application increase the atomization area relative to the conventional single hole heating structure, have larger smoke, are less likely to be blocked (if one atomization hole 101 is blocked, the other atomization hole 101 can still be used), and can enhance the air convection 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 portion 20 is arranged around the two atomization holes 101, so that the two atomization holes 101 can be uniformly heated, the atomization is complete and is less likely to be burned, and the electronic cigarette can better restore the taste of tobacco oil.

[0043] The present application is not limited to the details of the foregoing description, and modifications and variations can be made by those skilled in the art without departing from the spirit and scope of the application as defined in the claims and equivalents thereof.
