  • the liquid guide part 13 may be a ceramic, for example, the liquid guide part 13 includes one or more porous ceramic parts.
  • the liquid guide part 13 and the liquid storage part 14 may be an integral porous ceramic body integrally molded.

  • one of the liquid guide part 13 and the liquid storage part 14 is a ceramic and the other is e-liquid absorbing cotton, and the e-liquid absorbing cotton may be bonded to the ceramic, for example, the liquid guide part 13 includes one or more porous ceramic parts and one or more pieces of e-liquid absorbing cotton, and the liquid guide part 14 includes one or more porous ceramic parts and one or more pieces of e-liquid absorbing cotton. In this way, the cost, the mounting space, and the efficiency of absorbing and penetrating e-liquid are taken into account.
  • the liquid guide body 1 further includes a liquid guide part 13, where the liquid guide part 13 is a part of the liquid guide body 1 that is between the liquid guide side surface 11 and a part that is obtained through translating the liquid storage side surface 12 to the liquid guide side surface 11 by 0.5 mm to 1.5 mm.
  • an orthographic projection area of the liquid guide part 13 is smaller than or equal to an orthographic projection area of the liquid storage part 14.
  • the liquid guide part 13 and the liquid storage part 14 can be made of different materials, and the liquid guide part 13 may be made of a material having high liquid absorption capacity, while the liquid storage part 14 may be made of a material having high temperature resistance.
  • the liquid guide part 13 can lengthen a path of the absorption and the permeation of the e-liquid by the liquid guide body 1 and increase e-liquid capacity for the vaporization, and the liquid guide part 13 may be a part of the liquid guide body 1 that is between the liquid guide side surface 11 and a part that is obtained through translating the liquid storage side surface 12 to the liquid guide side surface 11 by 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, or 1.5 mm.
  • a step surface 15 located in a circumferential direction of the liquid guide part 13 may be formed between the liquid guide part 13 and the liquid storage part 14, thereby improving the liquid absorption efficiency of the liquid guide part 13 and ensuring the vaporization effect and stability of the e-liquid by the heating body 2 on the liquid storage part 14.
  • the liquid storage part is 14 configured as a cuboid shape
  • the liquid guide part is 13 configured as a cuboid shape, a frustum of trapezoid prim shape, or a frustum of triangular prim shape.
  • the liquid guide part 13 is arranged in a more diverse way, which can be applied to different use scenarios.
  • a surface of the liquid guide part 13 connected to the liquid storage part 14 is a flat surface, which facilitates the connection between the liquid storage part 14 and the liquid guide part 13.
  • an area of the liquid absorbing region is smaller than or equal to an area of the vaporization region. That is, the e-liquid absorbed by the liquid absorbing region may fully penetrate to at least part of the surface of the vaporization region, so that the e-liquid absorbed by the liquid absorbing region may be prevented from accumulating in a low temperature area outside the vaporization region due to excessive penetration, resulting in "e-liquid frying", thereby preventing liquid leakage, improving the utilization efficiency of the e-liquid absorbed by the liquid absorbing region, ensuring the vaporization purity of the smoke in the vaporization cavity 42, and improving the inhalation experience of the user.
  • the area of the liquid absorbing region is 9% to 95% of the area of the vaporization region, for example, the area of the liquid absorbing region may be 9%, 20%, 30%, 40%, or 50% of the area of the vaporization region, to ensure the utilization efficiency of the e-liquid absorbed by the liquid absorbing region.
  • the area of the liquid absorbing region may be set to be close to the area of the vaporization region, for example, the area of the liquid absorbing region may be 60%, 70%, 80%, 90%, or 95% of the area of the vaporization region.
  • the liquid guide side surface 11 is configured as a flat surface, a polyline curved surface, an arc-shaped curved surface, or a spherical surface.
  • the shape of the liquid guide side surface 11 is more regular, which is convenient for processing and manufacturing.
  • the absorbing area of the liquid absorbing region on the liquid storage part 14 may be increased to improve the liquid absorption efficiency.
  • the liquid storage side surface 12 is configured as a flat surface, a polyline curved surface, an arc-shaped curved surface, or a spherical surface.
  • the shape of the liquid storage side surface 12 is more regular, which is convenient for processing and manufacturing.
  • a heating area of the vaporization region on the liquid storage part 14 may be increased to improve the vaporization efficiency, so that a vaporization volume of the e-liquid on the vaporization region may reach 95% to 98% of a volume of the e-liquid on the liquid storage side surface 12, which effectively avoids generation of vaporization condensate.
  • FIG. 4 to FIG. 5 schematic diagrams of a two-dimensional arc-shaped curved surface of a liquid storage side surface 12 are given.
  • the vaporization core 200 for the electronic cigarette further includes a vaporization core sealing member 3, where the vaporization core sealing member 3 is sleeved on the liquid guide body 1, the vaporization core sealing member 3 has a liquid flowing opening 31, and the at least a part of the liquid guide side surface 11 is exposed from the liquid flowing opening 31 to form a liquid absorbing region.
  • the vaporization core sealing member 3 may seal a circumferential gap of the liquid guide body 1, so that the e-liquid in the liquid storage cavity 41 is prevented from leaking directly into the vaporization cavity 42 through the circumferential gap of the liquid guide body 1 without passing through the liquid guide body 1, thereby ensuring the vaporization rate of the e-liquid and thus ensuring the utilization rate of the e-liquid.
  • the liquid flowing opening 31 is arranged to enable the e-liquid in the liquid storage cavity 41 to be in contact with the liquid guide body 1, so that the e-liquid easily flows to the liquid absorbing region through the liquid flowing opening 31.
  • an electronic cigarette according to an embodiment of the present invention is described with reference to accompanying drawings, and the electronic cigarette includes the cartridge 100 according to the foregoing embodiments of the present invention and a cigarette rod.
  • liquid capacity required for single-inhalation vaporization can be matched, thereby ensuring both the amount of vapor output and the sufficient vaporization of the e-liquid.
