Description

Technical Field

[0001] The present invention relates to the technical field of electronic atomization, and in particular to an atomization core and an electronic atomization device thereof. Background Art

[0002] The atomizer core currently used in the field of electronic atomization generally includes a heating element and a liquid guide. The liquid guide is generally a flat liquid guide, a grooved liquid guide and a cylindrical liquid guide, and a corresponding heating element is arranged to match it. The arrangement of the flat liquid guide and the grooved liquid guide makes the atomized gas generally flow upward from the bottom of the liquid guide along the side wall of the liquid guide. The arrangement of the cylindrical liquid guide generally makes the atomized gas flow straight upward along the cylindrical inner wall, which easily leads to oil explosion when the smoke oil is heated. The straight-through airflow channel can easily inhale the oil explosion or the larger aerosol particles of the atomization into the mouth through the airflow during suction, resulting in a bad experience. Moreover, such an arrangement makes it impossible to form a relatively closed atomization bin, so that the space around the atomization surface is relatively wide, and the formed atomized gas cannot gather and become thick. In addition, the straight-through arrangement between the air inlet and the atomization area causes the air outlet to be generally at a lower position, which easily leads to oil leakage at the air inlet end.

[0040] The terms "first", "second", etc. are used only for descriptive purposes and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features. "Multiple" means two or more, unless otherwise clearly and specifically defined.

[0041] The above terms are only for the convenience of description and should not be construed as limitations on the present technical solution.

[0042] Embodiment 1, as Figure 1-Figure 9As shown, an atomizer core includes an upper cover 100 and a base 300. A heating atomizer assembly 200 and an electrode 400 are arranged between the upper cover 100 and the base 300. The heating atomizer assembly 200 includes a heating element 21 and a liquid-conducting body 22. The heating element 21 is attached to or embedded in the outer wall of the liquid-conducting body 22. The heating element 21 includes a heating circuit 212 and an electrode connector 211. The electrode 400 is connected to the electrode connector 211 of the heating element 21. The electrode 400 supplies power to the heating element 21. The shape of the heating circuit 212 of the heating element 21 matches the shape of the outer wall of the liquid-conducting body 22, so that the heating element 21 can be attached to or embedded in the outer wall of the liquid-conducting body 22. Further, a fixing piece can be further provided on the heating circuit 212 of the heating element 21, and the fixing piece is embedded in The guide liquid 22 is provided with an atomizing channel 221 which passes through the bottom and the top of the guide liquid 22, which means that the atomizing area of ​​the guide liquid 22 is on the outer wall of the guide liquid 22, and the atomizing channel 221 is in the guide liquid 22, so that the airflow direction of the atomized gas formed on the atomizing surface 225 is first downwardly converged to the air inlet end at the bottom of the atomizing channel 221. At this time, the atomized gas at the air inlet end of the atomizing channel 221 is relatively rich, and the taste will be richer. The atomized gas then flows from the air inlet end of the atomizing channel 221 to the air outlet end above the atomizing channel 221. The entire airflow direction of the atomized gas is circuitous. In this way, it is avoided that fried oil or large atomized particles are sucked into the mouth; a mounting groove 31 for accommodating the heating atomization component 200 is provided in the base 300, and the heating atomization component 200 can be completely accommodated in the mounting groove 31, and can also be partially accommodated in the mounting groove 31, and a closed atomization bin 500 is formed by the cooperation between the upper cover 100, the mounting groove 31 and the heating atomization component 200. Because of the close cooperation between the upper cover 100, the mounting groove 31 and the heating atomizer, the atomization bin 500 formed at this time has a smaller volume, so that the atomized gas is gathered in the atomization bin 500, and the atomized gas in the atomization bin 500 becomes more and more dense, and the atomization bin 500 is connected to the atomization channel 221, so that the atomized gas discharged into the atomization channel 221 is more dense and has a better taste. Better; an air inlet channel 32 is provided between the mounting groove 31 and the wall of the base 300, and the air inlet channel 32 is connected with a first air inlet port 33 provided on the upper part of the mounting groove 31 and a second air inlet port 34 provided on the base 300. It can be understood that air enters the air inlet channel 32 between the mounting groove 31 and the wall of the base 300 from the second air inlet port 34 on the base 300, and then enters the atomization bin 500 in the mounting groove 31 through the first air inlet port 33 on the upper part of the mounting groove 31. Such a design makes the air intake airflow direction of the gas not directly through the atomization channel 221, but first passes through a radial-axial-radial process, and then has a radial flow process. Such a setting raises the position of the air intake to prevent condensate or smoke liquid from flowing into the first air inlet port 33.

[0043] Working process of the atomizer core: When the atomizer core is working, air enters the air flow channel from the second air inlet 34, flows to the atomizer bin 500 through the second air inlet 34, and the heating element 21 generates heat to atomize the smoke liquid in the liquid guide 22, and the atomization forms atomized gas. The atomized gas and the air in the atomizer bin 500 form an aerosol, and the aerosol gathers in the atomization channel 221, flows out of the atomizer core through the atomization channel 221, and is finally inhaled by the smoker.

[0044] The liquid-guiding body 22 is a truncated cone structure that is larger at the top and smaller at the bottom. The truncated cone structure can be a curved truncated cone, for example, an inverted circular truncated cone or an elliptical truncated cone structure, whose bottom surface is circular or elliptical, and whose outer wall surface is a curved surface shape, that is, the atomizing surface 225 is a curved surface. The liquid-guiding body 22 can also be an inverted prism structure, and the bottom surface of the prism can be a polygon such as a triangle, a quadrilateral, or a pentagon, and its side surface is a structure surrounded by multiple quadrilaterals, that is, the atomizing surface 225 is a prism structure surrounded by multiple quadrilaterals, and the specific shape is not limited. The heating element 21 is arranged around the outer surface of the liquid-guiding body 22, and is a cylindrical structure that is larger at the top and smaller at the bottom and can be fitted or embedded with the liquid-guiding body 22. The shape of the heating element 21 is consistent with the corresponding liquid-guiding body 22. The shape of the outer wall of the liquid guide 22 is consistent with that of the outer wall, which means that the atomizing surface 225 of the liquid guide 22 is also a cone-shaped shape with a larger top and a smaller bottom. The area of ​​the atomizing surface 225 toward the atomizing channel 221 becomes smaller and smaller. The heating element 21 can be attached to or embedded in the outer wall of the liquid guide 22. The first air inlet 33 is arranged at the upper part of the mounting groove 31, that is, the airflow first flows through the end of the liquid guide 22 with a larger diameter, and the airflow flows downward along the cone-shaped atomizing surface 225 with a larger top and a smaller bottom, and flows to the atomizing channel 221. The area of ​​the atomizing surface 225 gradually decreases with the direction of the airflow, and the airflow channel in the atomizing area gradually decreases with the direction of the airflow, so that the atomized gas is more concentrated and richer, and the taste is richer, and it can also ensure that the smoke oil at various places on the atomizing surface 225 is fully utilized.

[0045] Of course, the liquid guide 22 can also be a cylindrical structure, such as Figure 5-Figure 6As shown, the heating element 21 is attached or embedded around the outer surface of the liquid-conducting body 22, and is also a cylindrical structure, that is, the atomizing surface 225 is also a curved surface. The heating element 21 heats the atomized liquid on the atomizing surface 225. In addition, a liquid inlet hole 229 is also provided on the top surface of the cylindrical liquid-conducting body 22. One or more liquid inlet holes 229 can be provided. The multiple liquid inlet holes 229 can also be connected to form a ring shape. The liquid inlet hole 229 is connected to the liquid inlet port 14 opened on the upper cover 100. The atomized liquid flows into the liquid guiding body 22 from the liquid inlet hole 229, and the area of ​​each point of the atomizing surface 225 toward the air inlet end of the atomizing channel 221 remains consistent. The airflow first flows through the upper end of the cylindrical liquid guiding body 22, and then flows downward along the cylindrical atomizing surface 225 to the atomizing channel 221, so that each point on the atomizing surface can be evenly atomized, and the taste is more delicate. In addition, in the actual production process, the cylindrical structure is easier to implement, and the uniformity and consistency of the finished product of the liquid guiding body 22 can also be better.

[0046] The atomization channel 221 can be arranged at the axial center of the liquid guiding body 22, or can be arranged off the center, can be parallel to the central axis, or can be arranged at an angle. This also means that the air inlet end of the atomization channel 221 is arranged at the bottom of the liquid guiding body 22, and the atomized gas needs to flow downward along the atomization surface 225 and then flow upward along the atomization channel 221. After the atomized gas passes through the circuitous path, it is not easy for the atomized large particles and the splashed smoke oil particles generated during the oil frying to be inhaled into the user's mouth. In addition, this design makes the middle atomization air guide pipe longer than the existing atomization air guide pipe, and the condensed liquid is not easy to climb into the user's mouth along the atomization air guide pipe.

[0047] like Figure 1-Figure 2 As shown, the top surface of the liquid-guiding liquid 22 is provided with a groove body 222, and the liquid inlet surface 224 of the liquid-guiding liquid 22 is the inner wall of the groove body 222. The groove body 222 can be a polygonal groove or a curved groove. The liquid-guiding liquid 22 of the groove body structure can increase the area of ​​the liquid inlet surface 224 of the liquid-guiding liquid 22. The liquid inlet surface 224 is connected to the liquid inlet port 14 provided by the upper cover 100. A portion of the atomized liquid can also be stored in the groove body 222, shortening the distance from the liquid inlet surface 224 to the atomizing surface 225 of the liquid-guiding liquid 22, and accelerating the liquid guiding speed of the liquid-guiding liquid 22. The distance from the inner wall of the groove body 222 to the corresponding atomizing surface 225 can be designed to be consistent or similar, so that the liquid inlet rate of the liquid-guiding liquid 22 at each location is not much different, and the atomized taste can be further improved. In addition to the above-mentioned groove body 222 structure, the top surface of the liquid-guiding liquid 22 can also be a plane structure, a convex structure, and a concave structure.

[0048] like Figure 1-Figure 2As shown, a connecting tube 23 for connecting the atomizing channel 221 and the atomizing air guide tube is provided above the atomizing channel 221 of the liquid-guiding body 22; the position of the connecting tube 23 is different according to the different structures of the top surface of the liquid-guiding body 22. When the top surface of the liquid-guiding body 22 is a groove body 222, the atomizing channel 221 is located at the bottom of the groove body 222, and the connecting tube 23 is pressed against the wall surface of the groove body 222 above the atomizing channel 221 to form a seal. The connecting tube 23 and the liquid-guiding body 22 can be separate structures, and the bottom of the groove body 222 of the liquid-guiding body 22 can be a planar structure or other structures. It is only necessary to provide a position around the outlet of the atomizing channel 221 at the bottom of the groove body 222 that can be abutted and sealed with the connecting tube 23. In this embodiment, the connecting tube 23 is pressed against the bottom surface of the planar groove body 222 and forms a seal. The bottom of the groove body 222 is designed to be flat in order to better achieve the sealing of the connecting tube 23 and the liquid guide 22. A liquid storage space is formed between the side wall of the groove body 222 and the connecting tube 23, and the liquid guide 22 stores the e-cigarette in the liquid storage space. Of course, the top surface of the liquid guide 22 can also be a non-groove body 222, such as a flat structure or a curved structure, forming a liquid inlet surface 224 of a flat structure or a curved structure. The connecting tube 23 is pressed against the flat or curved liquid inlet surface 224 above the atomization channel 221 and forms a Sealing; the connecting tube 23 abuts against the liquid guiding liquid 22 and forms a seal, preventing the smoke liquid from entering the atomization channel 221 from the connecting tube 23, preventing the un-atomized smoke liquid from being inhaled by the user, and the atomized gas in the atomization channel 221 is finally discharged through the atomization air guide tube; the connecting tube 23 and the liquid guiding liquid 22 can also be integrally formed, firstly, the slurry is cast on the mold to form the liquid guiding liquid 22, and a model of the connecting tube 23 is left on the mold, and the slurry is continued to be cast on the model to form the connecting tube 23. The setting of the integrated structure reduces the number of mold openings and also saves assembly steps.

[0049] The first air inlet 33 is at least one air inlet groove or air inlet hole arranged on the upper part of the mounting groove 31, and the air enters the atomization bin 500 through the first air inlet hole, and forms an aerosol with the atomized gas in the atomization bin 500; one air inlet groove or air inlet hole can be arranged, or multiple air inlet grooves or air inlet holes can be arranged, and the multiple air inlet grooves or air inlets can be arranged regularly or irregularly. Since the first air inlet 33 is arranged on the upper part of the mounting groove 31, and the heating atomization device is accommodated in the mounting groove 31, the air enters the atomization bin 500 from the upper part of the mounting groove 31, which is equivalent to being lifted to the air inlet end of the atomization bin 500, so that during use, condensation or oil leakage is not easy to occur at the first air inlet 33.

[0050] The second air inlet 34 is at least one air inlet hole arranged on the bottom surface of the base 300 outside the installation groove 31 or on the side wall of the base 300. Multiple air inlet holes can be arranged, and the multiple air inlet holes can be arranged discontinuously on the bottom surface of the base 300 or on the side wall of the base 300. Multiple air inlet holes can be arranged continuously on the bottom surface of the base 300 or on the side wall of the base 300. Air enters the air inlet channel 32 between the installation groove 31 and the wall of the base 300 from the second air inlet 34 to supply air to the first air inlet 33.

[0051] A convex edge 223 extends outward from the top of the liquid-guiding body 22, and the shape and size of the convex edge 223 match the shape and size of the notch of the mounting groove 31, so that the top surface of the convex edge 223 is flush with the top surface of the mounting groove 31, and the side wall of the convex edge 223 abuts the side wall of the mounting groove 31, and part of the upper cover 100 abuts against the mounting groove 31. This arrangement can better form a sealed atomization bin 500; of course, the top of the convex edge 223 can be slightly lower than the top of the mounting groove 31, so that the entire liquid-guiding body 22 is accommodated in the mounting groove 31; it can also be that the top of the convex edge 223 is higher than the top of the mounting groove 31. At this time, the side wall of the convex edge 223 abuts the upper cover 100, and the top of the mounting groove 31 abuts below the convex edge 223, so that the upper cover 100, the mounting groove 31, and the heating atomization assembly 200 form the atomization bin 500.

[0052] like Figure 7-Figure 8As shown, a plurality of grooves 222 are provided on the liquid inlet surface 224 of the liquid-guiding body 22. The arrangement of the grooves 222 can make the liquid inlet more uniform and sufficient. The convex edge 223 of the liquid-guiding body 22 can extend downward to form a circle of fixing parts 228. The fixing parts 228 abut against the bottom of the mounting groove 31. The fixing parts 228 can be made of a porous material. The arrangement of the fixing parts is to fix and limit the heating atomization component 200 to prevent the heating atomization component 200 from being skewed when being assembled to the mounting groove 31 of the base 300. The outer wall surface of the fixing part 228 is in sealing contact with the inner wall surface of the mounting groove 31, so that the heating atomization component is closer to the mounting groove 31. The fixing part 228 is provided with an air flow port 2280 connected to the first air inlet 33 on the mounting groove 31, so that the air flow in the atomization core is kept unobstructed. The arrangement of the fixing part 228 can also provide support strength for the liquid-guiding body 22, and at the same time have a heat insulation effect, effectively reducing the amount of air in the atomization bin 500. Heat overflows, and its porous material can also absorb condensate, playing a role in recycling condensate; and the electrode connector 211 of the heating element 21 is attached to the convex edge 223 of the liquid conductor 22, extends from the mounting groove 31 and is connected to the electrode 400. At this time, the upper cover 100 is sealed with the base 300, and an air inlet channel 32 is left between the side wall of the base 300 and the mounting groove 31, that is, the electrode connector 211 extends into the air inlet channel 32, and the electrode 400 is inserted into the air inlet channel 32 from the bottom of the base 300. The upper cover 100 is provided with an electrode mounting hole 11, and the electrode 400 is electrically connected to the electrode connector 211 of the heating element 21, and the top end of the electrode 400 is inserted into the electrode mounting hole 11. The electrode 400 connects the electrode connector 211 and inserts the electrode 400 into the electrode mounting hole 11 of the upper cover 100, so as to realize the connection between the electrode 400 and the electrode connector 211 and fix the upper cover 100, thereby supplying power to the heating element 21.

[0053] A support member 24 for supporting the heating atomization assembly 200 is provided at the bottom of the liquid-conducting body 22. At least one support member 24 is provided at intervals, that is, one support member 24 can be provided, or multiple support members 24 can be provided at intervals. The support member 24 can also be provided in a circle. The support member 24 is a porous structure. The liquid-conducting body 22 and the support member 24 can be an integrally formed structure. The support member 24 has a relatively high strength structure, which can provide structural support for the heating atomization assembly 200 and prevent the liquid-conducting body 22 from being affected by the continuous high temperature of the heating element 21. Its porous structure can also absorb condensed liquid. The support member 24 partially abuts against the bottom of the mounting groove 31, and the condensed liquid formed in the atomization bin 500, especially the condensed liquid formed at the bottom of the mounting groove 31, is recovered to the liquid-conducting body 22. A gap between the atomization bin 500 and the atomization channel 2 is left between the support member 24. 21 is connected to the air flow channel, so that the atomized gas formed in the atomizing surface 225 can reach the atomizing channel 221 through the air flow channel; or the support member 24 is arranged in a circle, and an air flow channel connecting the atomizing bin 500 and the atomizing channel 221 is left on the support member 24. Part of the support member 24 in a circle can abut against the bottom of the mounting groove 31, and part of it does not abut against the bottom of the mounting groove 31 to form an air flow channel connecting the atomizing bin 500 and the atomizing channel 221. In this way, the support member 24 plays a role in recovering the condensed liquid to the guiding liquid 22, and also plays a role in providing strength support to the guiding liquid 22.

[0054] The upper cover 100 is preferably a soft structure, preferably a soft silicone structure. The upper cover 100 cooperates with the base 300 to seal the heating atomization assembly 200 to prevent oil leakage. At least one circle of sealing ridges 12 is provided on the outer side thereof. One circle of sealing ridges 12 can be provided, or multiple circles of sealing ridges 12 can be provided. The sealing ridges 12 are provided to make the upper cover 100 fit tightly with the atomization shell to prevent the liquid in the liquid storage tank in the shell from leaking through the side wall of the upper cover 100.

[0055] A positioning piece 13 is provided on the inner wall of the upper cover 100. The positioning piece 13 can be a circle of protrusions arranged circumferentially along the inner wall of the upper cover 100. A positioning groove 35 is provided on the top of the mounting groove 31. The positioning groove 35 is a circle of grooves arranged circumferentially along the top of the mounting groove 31. The groove matches the protrusion so that the positioning piece 13 and the positioning groove 35 are plugged and fixed, so as to realize the positioning and fixing of the base 300 and the upper cover 100, and prevent the base 300 from shaking left and right in the upper cover 100, thereby affecting the sealing effect and avoiding affecting the atomization effect of the heating atomization assembly 200; the length of the positioning groove 35 can be designed to be longer than the length of the positioning piece 13, so that after the positioning groove 35 and the positioning piece 13 are plugged and fixed, a gap is left in the positioning groove 35. At this time, the gap will become the first air inlet 33, so that the first air inlet 33 does not need to be designed separately, making the structure simpler. Of course, the first air inlet 33 can also be set on the mounting groove 31 separately.
