Description

[Technical field]

[0001] The present invention relates to the technical field of atomization, and in particular to a porous ceramic atomization core and its electronic atomization device. [Background technology]

[0002] At present, in the atomization modules applied in the field, porous ceramics are a relatively mainstream liquid-guiding material in the atomization core. Porous ceramics are widely used due to their advantages such as excellent structural strength, uniform temperature due to the micro-pore structure, and heat resistance. The porous ceramic atomization core generally includes a heat generating module and a porous ceramic liquid-guiding module. During use, the heat generating module generates heat, and under the high temperature of the heat generating module, the porous ceramic liquid-guiding module generates a certain amount of smoke through atomization. When the user inhales, an airflow is generated to move the smoke and cause the vapor to flow out, thereby achieving the smoking effect.

[0003] However, the conventional porous ceramic atomizing core has the following disadvantages. In most conventional porous ceramic liquid-guiding atomizing cores, one liquid-guiding groove is opened in one porous ceramic, and a heating module is attached to the bottom of the porous ceramic. In this case, the liquid supply and liquid guide are concentrated in one liquid-guiding groove, so the liquid guide speed is slowed down, which affects the atomization effect of the porous ceramic atomizing core. In addition, since the heating module generally becomes very hot, if the porous ceramic atomizing core is used for a long period of time, cracks will occur on the surface of the porous ceramic in contact with the heating module, which may affect the use of the porous ceramic atomizing core. In addition, condensation is easily formed at the airflow supply port part below the porous ceramic atomizing core due to cooling. The generation of condensation not only leads to waste of the liquid for atomization, but also to damage electronic components. Summary of the Invention [Problem to be solved by the invention]

[0025] In order to make the technical features, objects and effects of the present invention more clearly understandable, specific embodiments of the present invention will be described in detail with reference to the drawings.

[0026] When an element is described as being "fixed" or "mounted" on another element, it may be located directly or indirectly on the other element, and when an element is described as being "connected" to another element, it may be connected directly or indirectly to the other element.

[0027] The directions or positions indicated by the terms "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "ceiling", "bottom", "inside", "outside", etc. are based on the directions or positions shown in the drawings, and are merely for convenience of description, and should not be construed as limiting the technical solution. Furthermore, the terms "first", "second", etc. are merely for convenience of description, and should not be construed as expressing or implying relative importance, or as suggesting the number of technical features. Furthermore, "plurality" means two or more than two, unless otherwise clearly and specifically limited.

[0028] In the first embodiment, as shown in FIG. 1 to FIG. 3, the porous ceramic atomizing core 20 includes a heating element 3 and a porous ceramic liquid guide 2. The porous ceramic liquid guide 2 includes a ceramic body 21 and a support part 22 extending downward from the ceramic body 21. The ceramic body 21 includes at least two protrusions 211. The number of the protrusions 211 is not specifically limited and is provided according to actual needs, but it is preferable to provide 2 to 4 protrusions. The arrangement of the protrusions 211 may be in a straight line shape, a triangular shape, or a rectangular shape. The multiple protrusions 211 are integrally connected via the connection part 23. A liquid guide groove 2111 is provided in each protrusion 211, and the heating element 3 is attached to the bottom of the liquid guide groove 2111. By providing multiple protrusions 211 on the porous ceramic atomizing core 20, multiple liquid supply points and liquid guide grooves 2111 are provided. As a result, the porous ceramic exhibits the effect of rapid liquid supply, and the liquid guide efficiency is improved, resulting in an optimized atomization effect. In addition, the support part 22 extends from the bottom surface of the ceramic body 21, and serves to support the porous ceramic body 21 and prevent the ceramic body 21 from cracking. In addition, since the support part 22 is also made of a porous ceramic body, it is possible to absorb the condensed liquid formed in the support part 22 and recover and reuse the condensed liquid. When the porous ceramic atomization core 20 is in operation, the atomization liquid enters the multiple protrusions 211. Each protrusion 211 is provided with a liquid guide groove 2111, and the atomization liquid passes through the liquid guide groove 2111 and is quickly guided to the bottom of the liquid guide groove 2111 that contacts the heating element 3. The heating element 3 generates heat to atomize the atomization liquid and form atomized vapor. In addition, the support 22 also absorbs the condensed liquid formed on the support 22, so that the condensed liquid is again atomized by the heating element 3 to form atomized vapor.

[0029] A notch 25 is provided on the surface of the side of the connecting part 23 and / or the side wall of the protruding part 211 to form an airflow path. One notch 25 may be provided, or two notches 25 may be provided. That is, one airflow path may be formed, or two airflow paths may be formed. The size and shape of the notch 25 are not limited. In addition to the notch 25 being provided on the surface of the side of the connecting part 23 and / or the side wall of the protruding part 211 described above, the notch in the present invention may be a notch formed by a difference in shape between the side of the connecting part 23 and / or the side wall of the protruding part 211 and the inner wall of the base. Alternatively, the connecting part 23 is provided with a return hole penetrating therethrough to form an airflow path. The shape and size of the return hole are not limited. The atomized steam can form an aerosol together with air in the airflow path, which is ultimately inhaled by the user.

[0030] The shape of the connection part 23 can be varied as follows. That is, when the ceramic body 21 includes two protrusions 211, the connection part 23 has an inclined structure inclined from one protrusion 211 to the other protrusion 211. Alternatively, the connection part 23 is formed so that two inclined surfaces converge to the center to form a roof structure. Also, or, when the ceramic body 21 includes a plurality of protrusions 211, the connection part 23 has an umbrella-shaped structure, and the umbrella-shaped connection part 23 connects the plurality of protrusions 211. The heating element 3 generates heat to atomize the atomization liquid and form atomized vapor. The atomized vapor flows upward. Also, when the atomized vapor is cooled, it forms condensed liquid. There is also an airflow path near the connection part 23, and since the airflow passes through, condensed liquid is very likely to form in the connection part 23. When the condensate accumulates to a certain degree, not only will the atomization liquid not be used effectively, resulting in waste of the atomization liquid, but the condensate may also fall downward and damage electronic components. In contrast, if the connection part 23 has an inclined surface structure inclined from one protruding part 211 to the other protruding part 211, the condensate can flow from one protruding part 211 to the other protruding part 211, and be collected in the liquid guide groove 2111 by the other protruding part 211, thereby realizing collection and use of the condensate. Alternatively, by making the connection part 23 a roof structure or an umbrella structure, the condensate is less likely to accumulate in the connection part 23. When the condensate flows directly to the bottom of the porous ceramic along the inclined surface of the roof structure or the inclined surface of the umbrella structure, it is heated again by the heating element 3 and atomized.

[0031] As shown in Fig. 3, a flange 24 extends outward from the top surface of the protruding portion 211 of the porous ceramic liquid guide 2. When the porous ceramic atomizing core is assembled, the porous ceramic liquid guide 2 is accommodated in the base with the rest of the top surface of the protruding portion 211 except for the flange 24, and the bottom surface of the flange 24 abuts against the top surface of the side wall of the base. This improves the sealing effect of the porous ceramic liquid guide 2. In addition, the flange 24 is provided and can be used as a pressure point, which is convenient for repair and removal.

[0032] The shape and structure of the support part 22 can be various. The support part 22 may have a hollow structure. When the support part 22 has a hollow structure, holes are provided at the corresponding positions of the connection part 23 to form an airflow path. This allows the completely atomized vapor to form an aerosol together with air in the airflow path, which is ultimately inhaled by the user. However, the atomization liquid that is not completely atomized may be mixed into the atomized gas, and may be cooled in the airflow path to form condensate. Therefore, the support part 22 is also made of porous ceramic. In this case, the inner wall of the support part 22 can absorb the condensate, which is guided to the bottom of the ceramic body 21 to be atomized again. Alternatively, the support part 22 has a solid structure. Such a support part 22 has a better structural strength and can better support the ceramic body 21, thereby preventing the ceramic body 21 from cracking. Alternatively, the support part 22 has a cylindrical structure with a closed lower end. A cavity is formed inside such support part 22, and the condensate absorbed by the outer wall of support part 22 can be stored in the internal cavity. In addition, the condensate in the internal cavity is transported to ceramic body 21. This makes it possible to more effectively absorb the condensate, and therefore makes it possible to more effectively recover and utilize the condensate.

[0033] Grooves are provided on the outer surface of the support part 22. Alternatively, holes are provided on the side wall of the support part 22. Alternatively, the outer surface of the support part 22 has an uneven, rough structure. The reason for providing such grooves is to increase the surface area of ​​the support part 22, that is, to increase the contact area with the condensate and to better realize the recovery and utilization of the condensate.

[0034] Grooves are formed on the outer surface of the ceramic body 21. Alternatively, holes are formed on the side wall of the ceramic body 21. Alternatively, the outer surface of the ceramic body 21 has an uneven, rough structure. All of these are provided in order to increase the surface area of ​​the ceramic body 21. Condensate may be formed in the area where the airflow passes. That is, condensate may also be formed on the outer surface of the ceramic body 21. Therefore, if the contact area with the condensate can be increased, the condensate can be better recovered and utilized, and waste of the atomization liquid can be avoided as much as possible.

[0035] The heating element 3 includes a heating circuit provided in the center and electrodes on both ends of the heating circuit. The heating element 3 may be a metal heating sheet, and the heating circuit of the heating element 3 is attached to the bottom of the ceramic body 21. In general, it is made of an alloy with high electrical resistivity, such as stainless steel, nickel-chromium, iron-chromium-aluminum, or nickel-iron, and the thickness may be between 0.03 and 0.2 mm, but there is no specific limit to the thickness. In addition, the heating circuit and electrodes can be formed by cutting or etching techniques. In addition, the electrodes are welded to contact with external electrodes.

[0036] In the second embodiment, as shown in FIG. 4 to FIG. 9, the electronic atomizer includes an atomizer casing 10. The porous ceramic atomizing core 20 in the first embodiment is provided in the atomizer casing 10. The porous ceramic atomizing core 20 is sandwiched between the upper and lower ends of the sealing member 30 and the base 40. A liquid storage space 50 is provided between the atomizer casing 10 and the porous ceramic atomizing core 20. The sealing member 30 is provided with a fitting port, and the porous ceramic atomizing core 20 is fitted and fixed in the fitting port. The sealing member 30 is provided with a liquid guide port 31 communicating with the liquid guide groove 2111 and an air vent 32 communicating with the air flow path. The base 40 is provided with a storage chamber, and the porous ceramic atomizing core 20 is attached to the storage chamber of the base 40. The base 40 is provided with an air flow supply hole 401. The air flow supply hole 401 of the base 40 is provided to allow the porous ceramic atomizing core 20 to flow through the fitting port 40 to form an air flow path. 20The notch 25 corresponds to and communicates with the notch 2111 of the porous ceramic atomizing core 20. The design of the sealing member 30 and the base 40 makes the assembly of the atomizing core simple and convenient. It also increases the reliability and makes it easier to assemble. When the electronic atomizing device is in operation, the liquid in the liquid storage space enters the liquid guide groove 2111 of the porous ceramic atomizing core 20 through the liquid guide port 31 of the sealing member 30. Airflow also enters through the airflow supply hole 401 of the base 40. The heating element 3 of the porous ceramic atomizing core 20 atomizes the atomizing liquid by heating it to form atomized vapor. The atomized vapor is mixed with the air entering through the airflow supply hole 401 to generate aerosol, which flows out through the air vent 32 of the sealing member 30 and is finally inhaled by the user.

[0037] As shown in FIG. 7, the protruding edge 24 extends outward from the ceiling surface of the protruding portion of the porous ceramic atomizing core 20. The porous ceramic atomizing core 20 is entirely housed in the housing chamber of the base 40, with the protruding edge 24 abutting against the ceiling surface of the side wall of the base 40. This improves the sealing effect of the porous ceramic atomizing core. Due to the limitations of the production technology of porous ceramics, it is difficult to control the dimensional tolerance very accurately. Therefore, after the porous ceramic atomizing core 20 is assembled in the base 40, there will be many gap spaces between the porous ceramic atomizing core 20 and the base 40. The protruding edge 24 is provided on the ceiling surface of the porous ceramic atomizing core to be higher than the ceiling surface of the base 40 in order to form a seal between the seal member 30 and the porous ceramic atomizing core 20. In addition, when the air pressure in the electronic atomizing device becomes excessively low due to consumption of liquid, the sealing silicone can be pushed open by the gas pressure, allowing gas to enter the liquid storage space, thereby achieving the effect of ventilation.

[0038] The porous ceramic atomizing core 20 is slightly smaller than the accommodation chamber of the base 40, and can be entirely accommodated within the accommodation chamber of the base 40. The sealing member 30 seals the base 40, thereby realizing the sealing of the porous ceramic atomizing core 20 and preventing liquid leakage from the porous ceramic atomizing core 20.
