[0002] At present, porous ceramic thick film printed heating elements have been widely used in existing electronic cigarette products due to their high atomization efficiency, excellent taste experience and high degree of automated production. In order to obtain a larger amount of smoke, ordinary electronic cigarette products usually use low thermal conductivity ceramic raw materials, coupled with the heating principle of thick film printing technology, to concentrate the heat in a smaller area, mostly in the shape of Ω, to obtain a higher atomization efficiency. Therefore, during the atomization process of the electronic cigarette oil, especially the first few puffs, the temperature of the ceramic heating element away from the heating area is relatively low, which does not have much effect on ordinary electronic cigarette oil, but this is not conducive to the oil conduction of high-viscosity atomized liquid, which can easily lead to insufficient oil supply, produce a burnt taste, and reduce the taste.

[0022] See also Figure 1As shown, the technical solution adopted in this specific embodiment is: it comprises a porous ceramic mesh 1 and a ceramic core body 2, wherein the porous ceramic mesh 1 is buried in the ceramic core body 2 and the porous ceramic mesh 1 protrudes from the ceramic core body 2, and a heating mesh 3 is arranged at the bottom of the ceramic core body 2, wherein the heating mesh 3 comprises a symmetrically arranged heating circuit 3-1, and a conventional ceramic core is usually large in size and has a long oil conduction heating stroke, resulting in a slow heating speed, and its printed circuit is arranged in a manner in which the heat surface is relatively concentrated, such as an Ω shape, and thus will appear in a high-viscosity atomized liquid. During use, the atomized liquid is easy to adhere to the low temperature area, which affects the overall oil supply speed, and the appearance of a scorched taste affects the taste. Therefore, in this embodiment, a large-area porous ceramic mesh is provided as an oil guide surface. The porous ceramic mesh 1 has a rectangular cross section with a side length of 5 mm, and the ceramic core body 2 has a rectangular cross section with a side length of 7 mm. The porous ceramic mesh and the ceramic core body have a small margin, thereby increasing the oil guide area. The high-viscosity atomized liquid will also be affected by the high-temperature area in the low-temperature area, thereby reducing the viscosity, which is helpful for the flow of the atomized liquid, ensuring the oil supply speed, and improving the taste;
[0023] At the same time, in this embodiment, the heating circuit adopts a symmetrical structural design, which is a double heating structure, which is conducive to rapid heating of the whole, and can better heat quickly under high-viscosity atomized liquid conditions to prevent the atomized liquid from sticking. The traditional single heating circuit structure has a relatively concentrated coverage area on the ceramic core body and a low overall temperature, so it is not well suited for heating high-viscosity atomized liquid.
[0024] More specifically, the porous ceramic mesh 1 and the ceramic core body 2 are an integral sintered structure, and sealant 4 is arranged around the connection between the porous ceramic mesh 1 and the ceramic core body 2. The surrounding isolation silicone seal isolates the smoke oil from leaking from the ceramics on both sides. The porous ceramic raw material can be selected from one or a mixture of alumina, zirconium oxide, silicon carbide, and titanium carbide. The thermal conductivity of the heating element is controlled within the range of 1-50w / (m·k), and the integrated structure is conducive to overall heat conduction.
[0025] To be more specific, the heating circuit 3-1 is set up with a multiple waveform structure, and the symmetrical parallel structure will not cause interference. When a problem occurs on one side, the other side can still continue to work, so that the user can still use it for a period of time after discovering the problem, and then repair or replace it. The raw materials of the heating circuit are stainless steel alloy sheets, iron-chromium-aluminum alloy sheets, and nickel-chromium alloy sheets. The resistor slurry formula can be adjusted as needed, and the resistance value can be adjusted to ensure stable operation of the heating circuit.
[0026] More specifically, a positive electrode sheet 3-2 and a negative electrode sheet 3-3 are respectively provided at both ends of the heating circuit 3-1.
[0027] To be more specific, a connecting sheet 3-4 is provided at the bottom of the heating circuit 3-1, the positive electrode sheet 3-2 and the negative electrode sheet 3-3. The connecting sheet 3-4 is buried in the ceramic core body 2, and the heating mesh circuit is buried as a whole in the ceramic core body, which is convenient for the overall installation of the heating element, not easy to contact with oil, and makes the taste better.
[0028] More specifically, the porous ceramic mesh 1 protrudes from the ceramic core body 2 with a thickness of 0.5 mm. The porous ceramic mesh protrudes from the ceramic core body with a thickness controlled at 0.5 mm, which can ensure the contact surface without affecting the oil guide stroke.
[0029] More specifically, the heating mesh 3 has a thickness of 0.05 mm, and the ultra-thin thickness of the heating mesh is more conducive to the miniaturized design of the heating element.
[0030] The working principle of the utility model is as follows: the porous ceramic mesh 1 is buried in the top of the ceramic core body 2, and a 0.05mm protruding part is left to increase the contact area with the atomized liquid, and the cross-sections of the porous ceramic mesh 1 and the ceramic core body 2 are both rectangular, and only a small distance is left between the edges of the porous ceramic mesh 1 and the ceramic core body 2. When heated in a high-viscosity atomized liquid environment, it can effectively prevent the higher viscosity atomized liquid from accumulating in the interval of lower temperature areas, so that the atomized liquid can be maintained within a viscosity range that can flow smoothly, so that it is not easy to produce a burnt taste and the taste is improved. At the same time, a symmetrical structure multi-corrugated heating mesh 3 is also arranged at the bottom of the ceramic core body 2, which cooperates with the large-area porous ceramic mesh 1 to effectively improve the heating efficiency.
[0031] The above description is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
