[0023] The general idea of the utility model is: the shell of the atomizer core is directly placed in the liquid storage chamber of the atomizer and is in direct contact with the atomized liquid to be atomized in the liquid storage chamber, and a heat transfer structure is formed on the outer surface of the shell to increase the contact area between the outer surface of the shell and the atomized liquid in the liquid storage chamber, so that the contact area between the shell and the atomized liquid in the liquid storage chamber is not the minimum contact surface. Because the outer surface of the shell in the traditional atomizer core is smooth and continuous (ignoring the oil inlet hole), the outer surface is in contact with the atomized liquid in the liquid storage chamber with the minimum contact surface when the shell meets a specific shape. For example, if the shell is required to be cylindrical, the outer surface is a cylindrical surface, if the shell is required to be an elliptical cylinder, the outer surface is an elliptical cylinder, and so on; and the heat transfer structure added in the utility model breaks the smoothness and continuity of the outer surface of the shell in the traditional atomizer core, changes the contact area between the outer surface and the atomized liquid in the liquid storage chamber, so that it is no longer the minimum contact surface. For example, the heat transfer structure can increase the contact area by convex or / and concave relative to the outer surface of the shell.
[0024] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the relevant drawings below. Typical embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solutions of the present application, rather than limitations on the technical solutions of the present application. In the absence of conflict, the embodiments of the present invention and the technical features in the embodiments can be combined with each other.
[0025] Embodiment 1
[0026] refer to Figure 1-3 In this embodiment, the atomizer core includes a shell 1 for assembling on the atomizer seat of the atomizer, an oil guide 2, and a heating core 3. After being assembled on the atomizer, the shell 1 is directly placed in the liquid storage chamber of the atomizer and directly contacts the atomized liquid to be atomized in the liquid storage chamber. The shell 1 is made of heat-resistant metal material or heat-resistant dense ceramic material, and the oil guide 2 is made of porous ceramic material.
[0027] The shell 1 is hollow inside and connected from top to bottom, and the outer surface of the shell 1 is provided with an oil inlet hole 101 connecting the inside and outside of the shell 1. Specifically, the shell 1 is cylindrical, and its top and bottom are both circular openings. The outer cylindrical surface of the shell 1 is evenly spaced along its circumferential direction to distribute a plurality of the oil inlet holes 101, which connect the inside and outside of the shell 1. In this embodiment, four oil inlet holes 101 are provided at equal heights. Of course, this number is only an example and is not intended to limit the present invention.
[0028] The oil guide 2 is mounted inside the housing 1 and obtains the atomized liquid from the liquid storage chamber through the oil inlet hole 101. Specifically, the oil guide 2 is also cylindrical and is unobstructed from top to bottom. The oil guide 2 is mounted inside the housing 1 and blocks all the oil inlet holes 101. More specifically, the inner diameter of the housing 1 is slightly larger than the outer diameter of the oil guide 2. Figure 2 Therefore, the area inside the shell 1 where the oil guide member 2 is mounted is slightly raised in the radial direction to form an annular structure 11 adapted to the outer diameter of the oil guide member 2. The oil guide member 2 is tightly mounted in the annular structure 11, and the oil inlet hole 101 passes through the annular structure 11 and is blocked by the outer wall of the oil guide member 2. The section inside the shell 1 between the top opening of the oil guide member 2 and the top opening of the shell 1 forms a mist outlet channel. The section inside the shell 1 between the bottom opening of the oil guide member 2 and the bottom opening of the shell 1 forms an air inlet cavity. The inside of the oil guide member 2 serves as an atomization cavity.
[0029] Among them, the heating core 3 is arranged in the oil guide part 2 to obtain the atomized liquid from the oil guide part 2 for heating and atomization. In this embodiment, the heating core 3 is inserted into the inner hole of the oil guide part 2 and is close to the inner hole side wall of the oil guide part 2. The heating core 3 is specifically a heating wire made of nickel-chromium, or tungsten wire, or silver alloy, or iron-chromium-aluminum and other materials, which is coiled in a spiral shape and close to the inner hole side wall of the oil guide part 2, and its two ends are axially led out from the atomization chamber and the air inlet chamber and connected to the electrodes on the atomization seat. It can be understood that in other embodiments, the assembly method of the heating core 3 can also be adjusted. This embodiment is only a schematic and is not used to limit the utility model.
[0030] For a conventional atomizer core, the outer surface of the shell 1 is a cylindrical surface, on which only the oil inlet hole 101 is opened. In this example, a heat transfer structure is formed integrally on the outer surface of the shell 1 to destroy the continuity of the outer surface of the shell 1 and increase the contact area between the outer surface of the shell 1 and the atomized liquid in the liquid storage chamber, so that the contact area between the shell 1 and the atomized liquid in the liquid storage chamber is not the minimum contact surface. Because the heating core 3 is inserted into the oil guide member 2, the heat is mainly concentrated within the length range of the oil guide member 2. For this reason, preferably, the heat transfer structure is located in the area of the outer surface of the shell 1 corresponding to the length range of the oil guide member 2. This area can also be understood as an annular area on the outer surface of the shell 1 that is flush with the oil guide member 2 above and below.
[0031] In this embodiment, the heat transfer structure is concave relative to the outer cylindrical surface of the housing 1. Figure 2-3 , the heat transfer structure is specifically formed by a plurality of blind grooves 1a recessed from the outer cylindrical surface of the shell 1, and the blind grooves 1a avoid all the oil inlet holes 101. For example, blind grooves 1a can be avoided above and below the oil inlet holes 101, or the lengths of some blind grooves 1a can be changed to interrupt / terminate at the position of the oil inlet holes 101. In this embodiment, the oil inlet holes 101 are located relatively high on the shell 1, and the bottoms of all the blind grooves 1a are flush, and the tops of the blind grooves 1a located between adjacent oil inlet holes 101 are also flush. There are two oil inlet holes 101 without blind grooves 1a above and below, and there are two oil inlet holes 101 with shorter blind grooves 1a below, and the tops of the blind grooves 1a located below the oil inlet holes 101 are distributed close to the circular edges of the oil inlet holes 101.
[0032] refer to Figure 3 The cross-sectional shape of each blind groove 1a may be consistent or inconsistent, and may be regular or irregular. The larger the cross-sectional area, the better the heat conduction effect.
[0033] Each blind groove 1a in this embodiment extends along the axial direction of the outer cylindrical surface of the housing 1, and a plurality of the blind grooves 1a are arranged along the circumferential direction of the outer cylindrical surface of the housing 1. Of course, in other embodiments, the extension direction of the blind groove 1a can also be changed, for example, it can be a curved trend such as an S-shape, a sawtooth shape, a rectangular wave shape, etc., it can also be a trend that is inclined relative to the axial direction of the outer cylindrical surface, and it can also be other irregular trends.
[0034] The working principle of this embodiment is: the heating core 3 generates heat, and transfers the heat to the oil guide member 2 and the shell 1 covering it through contact and radiation. The outer surface of the shell 1, especially the blind groove 1a serving as a heat transfer structure, transfers the heat to the atomized liquid to be atomized in the liquid storage chamber. Because the blind groove 1a is integrated with the outer surface of the shell 1, it can ensure that the heat source of the atomized liquid is the same as the heat source of the atomizer core body, which is provided by the internal heating core 3, thereby ensuring the consistency of heat distribution and atomization efficiency. This heat transfer mechanism regulates the molecular motion state and fluidity of the atomized liquid, so that the entire shell 1 is no longer in contact with the atomized liquid with the minimum contact surface (cylindrical surface), and the contact area with the atomized liquid can be increased. While increasing the contact surface, the mass of the entire shell can be reduced. The smaller the mass, the easier it is to increase heat. The design of this heat transfer structure not only improves the heat transfer efficiency, but also enables the fluidity of the atomized liquid to be precisely controlled. This is because for atomized liquids of different viscosities, the number of blind grooves 1a, or / and the extension trend, or / and the cross-sectional shape can be changed so that the shell and the external atomized liquid have different contact surfaces to adapt to atomized substances of different viscosities and provide more precise atomization control.
[0035] Embodiment 2
[0036] Except for the housing 1, the other structures of this embodiment are the same as those of the first embodiment, so only the structure of the housing 1 is shown. Figure 4 The difference between this embodiment and the first embodiment is that the heat transfer structure is a plurality of blind holes 1b formed by concavely forming the outer cylindrical surface of the housing 1, the cross section of the blind hole 1b perpendicular to its depth direction is gradually reduced toward the bottom of the blind hole 1b, and the cross section of the blind hole 1b is circular, that is, the blind hole 1b is a spherical arc hole. In this embodiment, the blind holes 1b are evenly distributed in the area corresponding to the length range of the oil guide member 2 on the outer surface of the housing 1.
[0037] Embodiment 3
[0038] refer to Figure 5 The only difference between this embodiment and the second embodiment is that the cross section of the blind hole 1b is polygonal, specifically hexagonal in this embodiment.
[0039] Of course, it is understandable that, in fact, the shape of the blind hole 1b is not limited to that shown in the second and third embodiments, and may also be other regular or irregular shapes.
[0040] Embodiment 4
[0041] The difference between this embodiment and the above three embodiments is that the heat transfer structure is no longer in a concave manner, but in a convex manner. Figure 6The heat transfer structure in this embodiment is formed by a plurality of convex points 1c protruding from the outer cylindrical surface of the housing 1. The cross section of the convex point 1c perpendicular to its height direction gradually decreases toward the top of the convex point 1c. The cross section of the convex point 1c is circular, that is, the convex point 1c is a spherical arc convex. Of course, the cross section of the convex point 1c can also be a polygon. Similarly, the cross section of the convex point 1c can be various regular or irregular shapes.
[0042] In addition, in this embodiment, in order to ensure the assembly of the atomizer core, the outer surface of the housing 1 is divided into three annular areas S1, S2, and S3, namely, upper, middle, and lower. The upper annular area S1 and the lower annular area S3 are used for assembly with other structures of the atomizer. The radial dimensions of the upper annular area S1 and the lower annular area S3 are consistent and slightly larger than the radial dimensions of the middle annular area S2, that is, the upper annular area S1 and the lower annular area S3 are protruding relative to the middle annular area S2. The middle annular area S2 corresponds to the length range of the oil guide 2. The convex point 1c of this embodiment is only set in the middle annular area S2, and the protruding height of the convex point 1c does not exceed the protruding height of the upper annular area S1 and the lower annular area S3 relative to the middle annular area S2.
[0043] It can be understood that the shell in the above embodiment is cylindrical, which is not used to limit the present invention, but is only an example. In fact, the shell can also be waist drum-shaped, elliptical cylindrical, polygonal cylindrical, etc. These are simple deformations of the present embodiment. As long as a heat transfer structure that increases the contact area between the outer surface and the atomized liquid in the liquid storage chamber is integrally formed on the outer surface of the shell of these shapes, so that the contact area between the shell and the atomized liquid in the liquid storage chamber is not the minimum contact surface, it is within the protection scope of the present invention.
[0044] It should be noted that the above embodiments can also be combined, for example, the blind groove 1a of the first embodiment can be combined with the blind hole 1b of the second or third embodiment, for example, a blind groove 1a is provided in the area corresponding to the length range of the oil guide member 2 on the outer surface of the housing 1, and the blind hole 1b is filled in the gap area between the blind grooves 1a. The concave formation method of the first, second and third embodiments can also be combined with the convex formation method of the fourth embodiment, which are all simple variations of the present embodiment and are within the protection scope of the present utility model.
[0045] In summary, the multi-viscosity oil precision flow control atomization core of the utility model has the following beneficial effects: the shell of the utility model is directly placed in the liquid storage chamber of the atomizer and is in direct contact with the atomized liquid to be atomized in the liquid storage chamber, and a heat transfer structure is formed integrally on the outer surface of the shell. The heat transfer structure increases the contact area between the outer surface of the shell and the atomized liquid in the liquid storage chamber, so that the contact area between the shell and the atomized liquid in the liquid storage chamber is not the minimum contact surface. Therefore, the structure can absorb the heat of the atomization core itself and effectively transfer it to the atomized liquid in the external liquid storage chamber. This design not only improves the heat transfer efficiency, but also the heat transfer mechanism regulates the molecular motion state and fluidity of the atomized liquid, thereby achieving more precise atomization control.
