[0016] In order to make the purpose, technical scheme and advantage of the embodiment of the present utility model more clear, the following will combine the drawings in the embodiment of the present utility model, and the technical scheme in the embodiment of the present utility model is clearly and completely described, obviously, the described embodiment is a part of the embodiment of the present disclosure, rather than all the embodiments. Based on the embodiment in the present utility model, all other embodiments obtained by ordinary skilled in the art without making the creative labor belong to the scope of the present utility model protection.
[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application.
[0018] The present disclosure provides an electronic cigarette. The electronic cigarette comprises a shell (not shown in the figure), a power supply assembly (not shown in the figure) and a porous ceramic atomization core 100. The porous ceramic atomization core 100 and the power supply assembly are installed in the shell, and the power supply assembly is electrically connected with the porous ceramic atomization core 100. The power supply assembly is used to supply power to the porous ceramic atomization core 100, so that the porous ceramic atomization core 100 in the porous ceramic atomization core 100 generates heat to atomize the tobacco tar.
[0019] In one embodiment, the porous ceramic atomization core 100 comprises a porous ceramic 1, a heating body 2 and a liquid guide body 3. The porous ceramic 1 is provided with a hollow through atomization channel 11 along its axial direction. The heating body 2 is a mesh-shaped body and is attached to the inner side wall of the atomization channel 11. The outer peripheral side of the porous ceramic 1 is provided with a groove 12, which is flush with the heating body 2. The liquid guide body 3 is wrapped around the groove 12. The oil guiding speed of the porous ceramic 1 is less than that of the liquid guide body 3. The oil guiding speed of the liquid guide body 3 is relatively fast, which can make the tobacco tar quickly enter the bottom surface of the groove 12, improve the oil guiding speed, and the oil guiding speed of the porous ceramic 1 is relatively slow compared with that of the liquid guide body 3, which can make the tobacco tar fully dispersed into multiple fine streams and seep into the micropores of the porous ceramic 1, thereby avoiding the paste core.
[0020] In the present embodiment, the porous ceramic atomization core 100 reduces the single-side wall thickness of the porous ceramic 1 in the effective heating area of the heating body 2. The part with reduced ceramic wall thickness can be matched with a cotton material with faster oil guiding speed. Specifically, one or more layers of cotton (cotton layer) of the same material or different materials are wrapped or wrapped around the reduced / thinned ceramic wall, and the best atomization effect can be achieved by matching the cotton material with different gradient liquid guiding speeds without changing the ceramic base material according to the required effect and scheme of the electronic cigarette.
[0021] The porous ceramic atomizing core 100 provided by the embodiment, the wall thickness of the porous ceramic 1 is too thin to cause sintering not to be shaped or the ceramic strength after shaping to be insufficient, and the wall thickness is too thick to cause slow oil guiding speed; the outer peripheral side of the porous ceramic 1 located in the heating area is designed to be thinned and grooved in combination with the structural strength and the oil guiding speed. In the embodiment, the single-side total wall thickness L1 of the porous ceramic 1 is 20 mm-25 mm, for example, can be 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, etc.; the depth D1 of the groove 12 can be 1 mm, 2.5 mm, 3 mm, 5 mm, etc. The thickness L2 of the liquid guide body 3 is 5 mm-20 mm, for example, can be 15 mm, 16 mm, 18 mm, 20 mm, etc. Since the thickness L2 of the liquid guide body 3 is greater than the depth D1 of the groove 12, part of the liquid guide body 3 is accommodated in the groove 12 after assembly, and the two ends of the groove 12 can limit the displacement of the liquid guide body 3, so as to fix the liquid guide body 3 on the outer side wall of the porous ceramic 1.
[0022] In one embodiment, the liquid guide body 3 is formed by laminating and curling several layers of sheet cotton. The cotton has good liquid guiding speed due to its large porosity, and the two ends of the liquid guide body 3 are overlapped to form side ears. The liquid guide body 3 is flax and / or non-woven fabric. Flax has better high-temperature resistance than non-woven fabric, and non-woven fabric has better liquid guiding speed than flax. The liquid guide body 3 combines flax and non-woven fabric to have the characteristics of fast liquid guiding and high-temperature resistance.
[0023] Specifically, the inner layer 31 of the liquid guide body 3 is two layers of flax with different densities, and the outer layer 32 is non-woven fabric. Specifically, the inner layer 31 needs to have good heat resistance when contacting the porous ceramic 1, and the outer layer 32 needs to have good liquid guiding speed when contacting the atomizing substrate; the liquid guide body 3 adopts the distribution mode of the inner layer 31 of flax and the outer layer 32 of non-woven fabric, which on the one hand makes the liquid guiding speed of the liquid guide body 3 gradually decrease from outside to inside, avoiding liquid leakage caused by too fast oil guiding speed of the liquid guide body 3, and on the other hand enables the liquid guide body 3 to withstand the high temperature of the porous ceramic 1 heating to avoid the paste core.
[0024] In one embodiment, as shown in Figure 1 The porous ceramic 1 is in a cylindrical shape, and correspondingly, the atomizing channel 11 is a through hole in a cylindrical shape. Here, the cylindrical shape of the porous ceramic 1 enables the porous ceramic 1 to be closely attached to the inner wall of the oil cup, avoiding the leakage of e-liquid in the oil cup from the connection between the porous ceramic 1 and the oil cup, and enabling the atomizing channel 11 to be in a cylindrical shape, so that the heating body 2 can be closely attached to the inner side wall of the atomizing channel 11, avoiding the problem of the heating body 2 being warped and poorly attached.
[0025] The above is only the specific implementation manner of the present application, so that those skilled in the art can understand or implement the present disclosure. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Accordingly, the present application is not to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
