At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

Unless otherwise specified, the terms "connection" and "linkage" used in this application include both direct and indirect connections.

[0028] In related technologies, the heating element is a hollow cylinder with heating metal plates on its inner wall to provide heat for atomization. The liquid guide 10 of the heating element uses a type of ceramic material. If the ceramic material is highly liquid-conductive, the heating element may experience insufficient liquid storage and leakage; if the ceramic material is highly liquid-storing, the heating element may experience insufficient liquid conduction. Both of these situations can lead to dry burning, burnt coils, or off-flavors in e-cigarette use due to insufficient liquid supply or storage, thus affecting the consumer's experience.

[0029] This application provides a heating element suitable for use in an atomizer, which can solve the above-mentioned problems.

[0030] Please refer to Figures 1 to 3 As shown, the heating assembly has a first direction Z. The heating assembly includes a liquid guide 10 and a heating element 20. The liquid guide 10 includes a first liquid guide section 11, a liquid storage section 12, and a second liquid guide section 13. The first liquid guide section 11, the liquid storage section 12, and the second liquid guide section 13 are arranged sequentially along the first direction Z. The first liquid guide section 11, the liquid storage section 12, and the second liquid guide section 13 are all porous material components. The average pore diameter of the first liquid guide section 11 and the average pore diameter of the second liquid guide section 13 are greater than the average pore diameter of the liquid storage section 12. The heating element 20 is connected to the liquid storage section 12.

[0031] In this embodiment, the first direction Z is the height direction of the heating element and also the height direction of the atomizer on which the heating element is provided. Along the first direction Z, the first liquid guiding part 11, the liquid storage part 12, and the second liquid guiding part 13 are arranged sequentially, that is, the first liquid guiding part 11 and the second liquid guiding part 13 are arranged on opposite sides of the liquid storage part 12.

[0032] In the heating component of this application embodiment, the first liquid guiding part 11, the liquid storage part 12, and the second liquid guiding part 13 are all porous material parts. The average pore diameter of the first liquid guiding part 11 and the average pore diameter of the second liquid guiding part 13 are greater than the average pore diameter of the liquid storage part 12. Therefore, the first liquid guiding part 11 and the second liquid guiding part 13 have stronger liquid guiding ability than the liquid storage part 12, and the liquid storage part 12 has stronger liquid storage ability than the first liquid guiding part 11 and the second liquid guiding part 13. The heating element 20 is connected to the liquid storage part 12, and the heating element 20 heats the liquid storage part 12.

[0033] When the heating element is in use, the first liquid guiding section 11 and the second liquid guiding section 13 can quickly provide and replenish the aerosol generating matrix to the intermediate liquid storage section 12, ensuring atomization. Furthermore, the liquid storage section 12 has a strong liquid storage capacity; the aerosol generating matrix guided by the first liquid guiding section 11 and the second liquid guiding section 13 can be stored within the liquid storage section 12, ensuring atomization while also helping to reduce the risk of leakage. Therefore, the heating element possesses both high liquid conductivity and high liquid storage capacity. During atomization, the heating element can avoid abnormal e-cigarette inhalation caused by insufficient liquid supply or storage, such as dry burning, burnt coil, or off-flavor, which negatively impact the consumer's experience.

[0034] It is understandable that when the heating component is in use, the aerosol generating matrix guided by the first liquid guiding section 11 and the second liquid guiding section 13 can be stored in the liquid storage section 12, and the aerosol generating matrix in contact with the outer periphery of the liquid storage section 12 can also be stored in the liquid storage section 12.

[0035] In some embodiments, the first liquid guiding portion 11 has a first end connected to the liquid storage portion 12 and a second end away from the liquid storage portion 12. The cross-sectional area of ​​the first end of the first liquid guiding portion 11 in the direction perpendicular to the first direction Z is greater than the cross-sectional area of ​​the second end of the first liquid guiding portion 11 in the direction perpendicular to the first direction Z. The cross-sectional area of ​​the first end of the first liquid guiding portion 11 in the direction perpendicular to the first direction Z refers to the cross-sectional area of ​​the first end of the first liquid guiding portion 11 on the section passing through the first end of the first liquid guiding portion 11 and perpendicular to the first direction Z. Similarly, the cross-sectional area of ​​the second end of the first liquid guiding portion 11 in the direction perpendicular to the first direction Z refers to the cross-sectional area of ​​the second end of the first liquid guiding portion 11 on the section passing through the second end of the first liquid guiding portion 11 and perpendicular to the first direction Z.

[0036] In this embodiment, the direction from the first end to the second end of the first liquid guiding part 11 is parallel to the first direction Z. A cross-section perpendicular to the first direction Z is taken, and the cross-sectional area of ​​the first end of the first liquid guiding part 11 is larger than the cross-sectional area of ​​the second end. The first liquid guiding part 11 has a variable cross-section structure, and the average distance from the outer wall of the first liquid guiding part 11 to the liquid storage part 12 is relatively short. The first liquid guiding part 11 can quickly provide the aerosol generation matrix to the liquid storage part 12, ensuring atomization.

[0037] In some embodiments, the surface of the first liquid guiding portion 11 facing away from the liquid storage portion 12 is a first arc surface 14, which protrudes in the direction away from the heating element 20. In this embodiment, the first arc surface 14 is an arc surface that protrudes in the direction away from the heating element 20, which is convenient to process; moreover, the average distance from the first arc surface 14 to the liquid storage portion 12 is relatively short, and the first liquid guiding portion 11 can quickly provide the aerosol generation matrix to the liquid storage portion 12 to ensure atomization.

[0038] In some embodiments, the second liquid guiding portion 13 has a first end connected to the liquid storage portion 12 and a second end away from the liquid storage portion 12. The cross-sectional area of ​​the first end of the second liquid guiding portion 13 in the direction perpendicular to the first direction Z is larger than the cross-sectional area of ​​the second end of the second liquid guiding portion 13 in the direction perpendicular to the first direction Z. The cross-sectional area of ​​the first end of the second liquid guiding portion 13 in the direction perpendicular to the first direction Z refers to the cross-sectional area of ​​the first end of the second liquid guiding portion 13 on the section passing through the first end of the second liquid guiding portion 13 and perpendicular to the first direction Z. Similarly, the cross-sectional area of ​​the second end of the second liquid guiding portion 13 in the direction perpendicular to the first direction Z refers to the cross-sectional area of ​​the second end of the second liquid guiding portion 13 on the section passing through the second end of the second liquid guiding portion 13 and perpendicular to the first direction Z.

[0039] In this embodiment, the direction from the first end to the second end of the second liquid guiding part 13 is parallel to the first direction Z, and a cross-section is made perpendicular to the first direction Z. The cross-sectional area of ​​the first end of the second liquid guiding part 13 is larger than the cross-sectional area of ​​the second end of the second liquid guiding part 13. The second liquid guiding part 13 has a variable cross-section structure. The average distance from the outer wall of the second liquid guiding part 13 to the liquid storage part 12 is relatively short. The second liquid guiding part 13 can quickly provide the aerosol generation matrix to the liquid storage part 12 to ensure atomization.

[0040] In some embodiments, the surface facing away from the liquid storage section 12 is a second arc surface 15, which protrudes in the direction away from the heating element 20. In this embodiment, the second arc surface 15 is an arc surface that protrudes in the direction away from the heating element 20, which is convenient to process; moreover, the average distance between the second arc surface 15 and the liquid storage section 12 is relatively short, and the second liquid guiding section 13 can quickly provide the aerosol generation matrix to the liquid storage section 12 to ensure atomization.

[0041] In some embodiments, the sidewall of the liquid storage portion 12 is parallel to the first direction Z; or, the sidewall of the liquid storage portion 12 is a third arc surface protruding in a direction away from the heating element 20.

[0042] In this embodiment of the application, the liquid storage section 12 has a hollow columnar structure, with its sidewall parallel to the first direction Z. This can be referred to... Figure 4 As shown, in the cross-section through the axis of the liquid-conducting 10, the side wall of the liquid storage section 12 is a straight segment. Along the first direction Z, the side wall of the liquid storage section 12 is a third arc surface protruding away from the heating element 20, so in the cross-section through the axis of the liquid-conducting 10, the side wall of the liquid storage section 12 is an arc segment.

[0043] In some embodiments, the liquid guide 10 is spherical. Spheres have the advantages of being easy to process and having high structural strength.

[0044] In some embodiments, in the first direction Z, the height of the liquid guide 10 is H1, and the height of the liquid storage section 12 is H2, satisfying that H1 / 2 ≤ H2 < H1. When the height H2 of the liquid storage section 12 satisfies the above range, the heating component has better liquid storage performance to ensure atomization.

[0045] In practical applications, the height H2 of the liquid storage section 12 can be set according to usage requirements. For example, the height H2 of the liquid storage section 12 can be 1 / 2, 9 / 16, 5 / 8, 11 / 16, 3 / 4, 13 / 16, 7 / 8, 15 / 16 of H1, as well as several other ratios between the above ratios.

[0046] In some embodiments, in the first direction Z, the height of the liquid guiding 10 is H1, and the height of the first liquid guiding part 11 is H3, satisfying H1 / 8 ≤ H3 ≤ H1 / 4. When the height H3 of the first liquid guiding part 11 satisfies the above range, the heating component has better liquid guiding performance to ensure atomization.

[0047] In practical applications, the height H3 of the first liquid guiding part 11 can be set according to the usage requirements. For example, the height H3 of the first liquid guiding part 11 can be 1 / 8, 5 / 32, 3 / 16, 7 / 32, 1 / 4 of H1, as well as several other ratios between the above ratios.

[0048] In some embodiments, the height of the second liquid guiding section 13 is H4, satisfying H1 / 8 ≤ H4 ≤ H1 / 4. When the height H4 of the second liquid guiding section 13 satisfies the above range, the heating component has better liquid guiding performance to ensure atomization.

[0049] In practical applications, the height H4 of the second liquid guiding section 13 can be set according to the usage requirements. For example, the height H4 of the second liquid guiding section 13 can be 1 / 8, 5 / 32, 3 / 16, 7 / 32, 1 / 4 of H1, as well as several other ratios between the above ratios.

[0050] In some embodiments, the liquid guide 10 is provided with a gas channel 16 that extends through the liquid guide 10, and the gas channel 16 is arranged along a first direction Z; the heating element 20 is disposed in the gas channel 16 and connected to the liquid storage section 12. Thus, the heating element 20 can be used to heat the aerosol generation matrix at the liquid storage section 12, and the gas channel 16 allows gas and aerosol to pass through.

[0051] In some embodiments, the first liquid guiding part 11, the liquid storage part 12, and the second liquid guiding part 13 are all porous material components. The porous material can be configured according to usage requirements. For example, the first liquid guiding part 11, the liquid storage part 12, and the second liquid guiding part 13 are porous ceramic material components. Alternatively, the first liquid guiding part 11, the liquid storage part 12, and the second liquid guiding part 13 are porous polymer components.

[0052] It is understandable that in actual use, when the first liquid guiding part 11, the liquid storage part 12, and the second liquid guiding part 13 are porous ceramic material parts, the first liquid guiding part 11, the liquid storage part 12, and the second liquid guiding part 13 can be either silicon-based porous ceramic parts or aluminum-based porous ceramic parts.

[0053] The first liquid guiding part 11 and the second liquid guiding part 13 can be made of the same material, or they can be made of different materials, depending on the specific application requirements.

[0054] In some embodiments, the heating element 20 is a metal heating element, for example, the heating element 20 is a mesh heating element with iron-chromium-aluminum or nickel-chromium-aluminum as the base material.

[0055] Reference Figure 2 As shown, the heating element 20 is connected to the connecting line 21 to connect to other components in the atomizer via the connecting line 21.

[0056] The material of the connecting wire 21 is also set according to the usage requirements. For example, the connecting wire 21 is nickel wire.

[0057] In some embodiments, refer to Figure 2 As shown, the liquid-conducting part 10 is spherical. In the first direction Z, the liquid-conducting part 10 is composed of three parts: the upper layer is the first liquid-conducting part 11, the middle layer is the liquid-storing part 12, and the upper layer is the second liquid-conducting part 13. The first liquid-conducting part 11 and the second liquid-conducting part 13 are porous materials with high liquid conductivity, and the liquid-storing part 12 is a porous material with high liquid storage capacity.

[0058] Regarding the first liquid guiding section 11, in the first direction Z, the height of the first liquid guiding section 11 from the surface of the liquid storage section 12 to the liquid storage section 12 gradually increases from the outer periphery to the middle. This structure ensures that the aerosol generating matrix on both the upper and lower sides can be quickly replenished to the airway wall and the liquid storage section 12, ensuring atomization. Moreover, the liquid storage section 12 has a strong liquid storage capacity, and the aerosol generating matrix guided from the first liquid guiding section 11 and the second liquid guiding section 13 can be stored in the liquid storage section 12, further ensuring atomization. Therefore, the heating element has both high liquid conductivity and high liquid storage capacity. During the atomization process, the heating element can avoid abnormal e-cigarette inhalation such as dry burning or off-flavor due to insufficient liquid supply or storage, which would affect the consumer's experience.

[0059] In one embodiment, an atomizer 100 is provided, which includes the heating element as described above. Because the heating element prevents abnormal e-cigarette inhalation due to insufficient liquid supply or storage, such as dry burning, burnt coil, or off-flavor, the atomizer 100 offers a superior user experience.

[0060] In related technologies, the heating element is a hollow cylinder with heating metal plates on the inner wall to provide heat for atomization. However, the heating element may experience insufficient liquid storage or insufficient liquid delivery. Both of these issues can lead to problems such as dry burning, burnt coils, or off-flavors in e-cigarettes. To address these problems, related technologies use a solution of wrapping the heating element with a liquid storage cotton layer to improve liquid delivery and storage. However, this solution increases the size of the storage chamber and makes it impossible to monitor the usage of the aerosol generation matrix. This also makes it prone to problems such as burnt coils and dry burning when the liquid is depleted, negatively impacting the consumer experience.

[0061] In some embodiments, the atomizer 100 includes a liquid storage chamber and a heating component as described above. The heating component is disposed inside the liquid storage chamber, and the space between the wall of the liquid storage chamber and the heating component is used only for distributing an aerosol generation matrix.

[0062] When using the heating element described above, the atomizer 100 of this embodiment avoids e-cigarette inhalation abnormalities such as burnt coils or off-flavors due to insufficient liquid supply or storage, because the heating element simultaneously possesses high liquid conductivity and high liquid storage capacity. Furthermore, the heating element does not need to be wrapped with a storage cotton; the space between the heating element and the wall of the storage chamber is solely used for the aerosol generation matrix, saving space occupied by the storage cotton. With the same storage capacity of the aerosol generation matrix, the storage chamber has a smaller volume. Without the obstruction of the storage cotton, the usage of the aerosol generation matrix can be observed, preventing problems such as burnt coils or dry burning when the aerosol generation matrix is ​​depleted. Therefore, the atomizer 100 of this embodiment does not produce e-cigarette inhalation abnormalities such as burnt coils or off-flavors, and has the advantage of a more compact structure, effectively improving the consumer experience.

[0063] In another embodiment, the atomizer 100 includes a liquid storage chamber and a liquid storage cotton, the liquid storage cotton wrapping the heating element, and the liquid storage cotton and the heating element are disposed inside the liquid storage chamber.

[0064] In one embodiment, an atomizing device is also provided, which includes an atomizer 100 as described above and a power supply 200, wherein the power supply 200 is used to provide electrical energy to the atomizer 100.

[0065] In this embodiment, the atomizer 100 may include a power supply component or may not include a power supply component; the atomizer 100 and the power supply 200 may be fixedly connected or detachably connected.

[0066] The atomizing device can be either a disposable or refillable product. For disposable atomizing devices, the atomizer 100 may not contain a power supply component, and the atomizer 100 and power supply 200 are fixedly connected. For refillable atomizing devices, the atomizer 100 may not contain a power supply component, and the atomizer 100 and power supply 200 are detachably connected, allowing them to be replaced as needed. The atomizing device can also be an external power bank-type atomizing device, in which the atomizer 100 includes a power supply component, and the atomizer 100 and power supply 200 are detachably connected.

[0067] The above-described atomizing device is only one embodiment of this application. Other atomizing devices with atomizers are also within the protection scope of this application. The specific internal structure of the atomizing device will not be described in detail.

[0068] In one specific embodiment, the liquid guide 10 is made of porous ceramic material, and the first liquid guide part 11, the liquid storage part 12 and the second liquid guide part 13 are made of the same material, as an example for illustration.

[0072] Weigh 45 parts of 300-200 mesh aggregate material, 15 parts of 300-400 mesh aggregate material, 40 parts of pore-forming material, and 50 parts of binder, and add them sequentially to the molten flow agent and stir evenly. This mixture is labeled as the second feed.

Then, use hot pressing molding to make the liquid storage part 12 in the mold. Finally, use hot pressing molding to make the other one of the first liquid guiding part 11 and the second liquid guiding part 13 in the mold. Demold and take the first blank out of the mold.

[0075] 3. Sintering: The first preform was placed in a sintering furnace for sintering. The sintering curve was as follows: the temperature was increased to 700℃-800℃ at a heating rate of 2℃ / min, and then held at 700℃-800℃ for 2 hours before cooling to obtain the first sample. The third sample had a spherical structure.

[0076] 4. Cleaning and testing: The first sample after sintering is cleaned and tested.

The second sample is a hollow cylindrical structure.

[0081] 4. Cleaning and testing: The second sample after sintering is cleaned and tested.

The third sample was a hollow cylindrical structure.

[0086] 4. Cleaning and testing: The third sample after sintering is cleaned and tested.

[0087] The performance of the first, second, and third samples is compared as shown in Table 1 below:

[0088] Table 1

[0089] project Liquid conduction rate Liquid storage capacity First sample 1.36 0.268 Second sample 1.26 0.156 Third sample 0.89 0.235

[0090] As can be seen from the data results in Table 1, the liquid conduction rate of the first sample is greater than that of the second sample and the third sample, and the liquid storage capacity of the first sample is greater than that of the second sample and the third sample. That is, the first sample in this application embodiment has both high liquid conduction and high liquid storage capacity.

[0091] Meanwhile, the liquid conductivity of the second sample is greater than that of the third sample, indicating that the second sample is a high-liquid-conductivity material.
