For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0036] The first embodiment of the utility model discloses a liquid storage cotton, see Figures 1-2 This embodiment provides a liquid storage cotton, including:

[0037] A first liquid storage layer 1 and a second liquid storage layer 2 are arranged axially;

[0038] The density of the first liquid storage layer 1 is lower than the density of the second liquid storage layer 2;

[0039] A first unit 201 and a second unit 202 are arranged on the radial cross section of the second liquid storage layer 2, wherein the density of the first unit 201 is lower than the density of the second unit 202;

[0040] The first liquid storage layer 1 and the second unit 202 are provided with a communicating through hole 3 .

[0041] It should be noted that in a specific implementation structure of this embodiment, the liquid storage cotton as a whole forms a first liquid storage layer 1 and a second liquid storage layer 2 which are axially distributed up and down, and the first liquid storage layer 1 is a uniform low-density material with a density of ρ1;

[0042] The structure of the second liquid storage layer 2 in this embodiment can be seen in Figure 2 , the material density of the second liquid storage layer 2 has a gradient distribution along the radial cross-section direction. In this embodiment, at least two regions with different material densities are provided on the radial cross-section of the second liquid storage layer 2, including a first unit 201 with a material density of ρ2 and a second unit 202 with a material density of ρ3, wherein the overall density distribution of the liquid storage cotton is set to ρ1<ρ2<ρ3;

[0043] Based on the structural setting in this embodiment, the first liquid storage layer 1 and the second unit 202 of the second liquid storage layer 2 are both provided with a through hole 3, the two through holes 3 are connected, and the through hole 3 of the second liquid storage layer 2 is used to connect with the heating element;

[0044] In this embodiment, see Figure 5 and Figure 6 Due to the difference in density, the first liquid storage layer 1, the first unit 201 and the second unit 202 will form pores of different sizes, porosities and surface energies, and there are different density combinations between the density ρ1 of the first liquid storage layer 1 and the densities ρ2 and ρ3 of the second liquid storage layer 2, thereby forming multiple density layered structures, and generating a surface energy gradient and Laplace pressure difference in each density layered structure, thereby optimizing the capillary effect in the transport direction, so that the atomized liquid in the first liquid storage layer 1 at the upper part is continuously transported to the second liquid storage layer 2 at the lower part under the dual effects of gravity and the enhanced capillary effect, thereby increasing the utilization rate of the atomized liquid in the first liquid storage layer 1;

[0045] Based on this embodiment, refer to Figure 7 , the high and low densities in the second liquid storage layer 2 are evenly distributed, and a Laplace pressure difference is also generated in the radial cross-sectional direction, so that the atomized liquid in the first unit 201 is continuously transported to the second unit 202 inside the liquid storage cotton;

[0046] In this embodiment, when the atomizing device is used, the atomized liquid is heated and atomized by the heating element on the side of the second unit 202 of the second liquid storage layer 2 close to the through hole 3. Based on the density gradient between the first liquid storage layer 1 and the second liquid storage layer 2 and the density gradient inside the second liquid storage layer 2, the liquid storage cotton as a whole forms a structural design of multiple Laplace pressure differences, which optimizes the longitudinal and lateral transport capacity of the atomized liquid in the liquid storage cotton, so that the atomized liquid is concentratedly transported to the heating element, thereby improving the utilization rate of the atomized liquid of the liquid storage cotton and increasing the service life of the atomizing device.

[0047] In a specific implementation of this embodiment, refer to Figure 2 and Figure 3 As shown, the first unit 201 wraps the second unit 202 .

[0048] In a more specific implementation of this embodiment, the through hole 3 is a central through hole between the first liquid storage layer 1 and the second liquid storage layer 2 .

[0049] In another more specific implementation of this embodiment, the through hole 3 is an eccentric through hole between the first liquid storage layer 1 and the second liquid storage layer 2 .

[0050] It should be noted that when a structure in which the first unit 201 wraps the second unit 202 is formed in the second liquid storage layer 2, the through hole 3 can be set at multiple locations in the liquid storage cotton. For example, when the through hole 3 is at the axial position of the first liquid storage layer 1 and the second liquid storage layer 2, a central through hole is formed, and when the through hole 3 is not set at the axial position of the first liquid storage layer 1 and the second liquid storage layer 2, it appears as an eccentric through hole. In a specific implementation, the through hole 3 is a central through hole or an eccentric through hole. On the radial cross-section of the second liquid storage layer 2, a second unit 202 and a first unit 201 arranged sequentially around the through hole 3 can be formed. Due to the difference in density between the inner and outer peripheries of the second liquid storage layer 2, the atomized liquid of the first unit 201 is promoted to continuously flow to the second unit 202, and then flow into the through hole 3 to be atomized by the heating element, thereby reducing the residual amount of the atomized liquid and improving the overall utilization rate of the atomized liquid around the liquid storage cotton.

[0051] In another specific implementation of this embodiment, refer to Figure 4 , the through hole 3 is an eccentric through hole between the first liquid storage layer 1 and the second liquid storage layer 2;

[0052] The distance between the proximal end of the second liquid storage layer 2 and the eccentric through hole is a first distance, the distance between the distal end of the second liquid storage layer 2 and the eccentric through hole is a second distance, and the difference between the second distance and the first distance is within a preset length range;

[0053] The first unit 201 and the second unit 202 are arranged in parallel.

[0054] It should be noted that, in the present embodiment, when the through hole 3 is an eccentric through hole, a distal hole end and a proximal hole end are formed on the radial cross section of the second liquid storage layer 2, and the distal hole end can be understood as the position of the second liquid storage layer 2 farthest from the through hole 3 on the radial cross section, and the proximal hole end can be understood as the position of the second liquid storage layer 2 closest to the through hole 3 on the radial cross section; further, the eccentric through hole can also be specifically arranged at the axial position or eccentric position of the second unit 202, and on the radial cross section of the second liquid storage layer 2, the distance between the proximal hole end and the eccentric through hole is the first distance A, and the distance between the distal hole end and the eccentric through hole is the second distance B. Through the matching relationship between the first distance A and the second distance B, the position of the eccentric through hole on the second unit 202 is further set, which can adapt to different transmission efficiency designs of the liquid storage cotton transmitting the atomized liquid to the heating element;

[0055] In a specific implementation, there may be various matching relationships between the first distance A and the second distance B. For example, the distance difference |AB| between the first distance A and the second distance B may be within a preset length range, or the ratio of the first distance A to the second distance B may satisfy a preset distance ratio.

[0056] In a preferred embodiment of the present structural design, the absolute value of the distance difference between the first distance A and the second distance B is greater than or equal to 3 mm. At this time, the first unit 201 and the second unit 202 are arranged in parallel, which can effectively reduce the residual amount of the atomized liquid.

[0057] In a more specific embodiment, see Figure 1 The radial cross-section of the first liquid storage layer 1 and the radial cross-section of the second liquid storage layer 2 are both circular, and the radial cross-sections of the two are of the same shape and tightly connected. In this case, the liquid storage cotton can be cylindrical. Of course, other shapes and structural designs are also possible, such as elliptical shapes. When designing, the radial cross-section of the connection between the first liquid storage layer 1 and the second liquid storage layer 2 can be tightly connected, without limitation.

[0058] In specific implementation, if the radial cross-sections of the first liquid storage layer 1 and the second liquid storage layer 2 are both circular, the central through hole can be understood as the through hole at the center of the circle, and the eccentric through hole is the through hole at a certain distance away from the center of the circle.

[0059] In a specific implementation, although the radial cross-section of the second liquid storage layer 2 is a circular or elliptical structure, the radial cross-section of the first unit 201 or the second unit 202 can be adjusted according to the limitations of the specific process. For example, when the radial cross-section of the second liquid storage layer 2 is an elliptical shape, the radial cross-section of the second unit 202 can adopt a circular, equilateral triangle, square or other structure. The first unit 201 surrounds the second unit 202 to form an elliptical shape, and the first unit 201 and the second unit 202 are wrapped in a structure; for example, when the radial cross-section of the second liquid storage layer 2 is a circle, the radial cross-sections of the first unit 201 and the second unit 202 are matching semicircular structures, and the first unit 201 and the second unit 202 are adjacent to each other.

[0060] In another specific embodiment, based on the solution of the first embodiment above:

[0061] In a specific embodiment, there are multiple first liquid storage layers 1, and the density of the multiple first liquid storage layers 1 gradually increases along the direction approaching the second liquid storage layer.

[0062] In a specific implementation of the present embodiment, the liquid storage cotton may include more than two liquid storage layers, for example, including axially arranged three-layer, four-layer, five-layer and other liquid storage layer designs. In specific implementation, for example, the first liquid storage layer 1 can be set to multiple. At this time, the density of the multiple first liquid storage layers 1 connected in sequence gradually increases in the direction close to the second liquid storage layer. For example, the density of the multiple first liquid storage layers 1 is ρ1, ρ4 and ρ5 respectively, then the overall density distribution in the liquid storage cotton is ρ1<ρ4<ρ5<ρ2<ρ3. Through the multiple density differences between the axially adjacent liquid storage layers, the atomized liquid in the low-density part of the liquid storage cotton is smoothly transported to the high-density part.

[0063] In another specific embodiment, there are multiple first units 201, and the density of the multiple first units 201 gradually increases along the direction close to the through hole; and / or there are multiple second units 202, and the density of the multiple second units 202 gradually increases along the direction close to the through hole.

[0064] In this embodiment, more than two density areas can be distributed along the radial direction on the radial cross-section of the second liquid storage layer 2, for example, including three, four or other areas with different material densities. In specific implementation, there can be multiple first units 201 and / or multiple second units 202, and the density of the multiple first units 201 and / or the density of the multiple second units 202 gradually increases in the direction close to the through hole. It can be understood that when multiple second units 202 are provided, the through hole 3 is arranged at the second unit 202 with the largest density, and the multiple density differences between adjacent density areas in the radial cross-section direction enable the interior of the second liquid storage layer 2 to have good liquid conduction ability, which helps to ensure the supply of atomized liquid.

[0065] It should be noted that, in some embodiments, the number, cross-sectional shape and connection relationship of the first unit and the second unit of the second liquid storage layer 2 of the liquid storage cotton in the above-mentioned embodiment can be set according to the application requirements of the liquid storage cotton, as long as the low-density part is transported to the high-density part between the first liquid storage layer 1 and the second liquid storage layer 2 and between the first unit and the second unit in the second liquid storage layer 2, so as to realize the longitudinal and transverse transportation of the atomized liquid in the liquid storage cotton to centrally transport the atomized liquid to the heating element for heating and atomization, there is no limitation.

[0066] The utility model also discloses an atomizer core, including a heating element (not shown) and the above-mentioned liquid storage cotton. The heating element is arranged on a side of the second unit of the second liquid storage layer close to the through hole. The heating element is used to heat and atomize the atomized liquid in the liquid storage cotton.

[0067] The utility model also discloses an atomization device, comprising the atomization core mentioned above.

[0068] The above is a detailed introduction to a liquid storage cotton, an atomizer core and an atomizer device provided by the utility model. For a person skilled in the art, according to the idea of ​​the embodiments of the utility model, there may be changes in the specific implementation method and the scope of application. In summary, the content of this specification should not be understood as a limitation on the utility model.
