Abstract
Description
Technical Field
[0001] This invention relates to the field of electronic atomizer technology, and particularly to a heating element, atomizing core, atomizing assembly, and atomizing device. Background Technology
[0002] Existing atomizing coils in atomizing devices fall into two main categories: ceramic coils and cotton coils. While the heating elements of these two types differ in shape, they are both made of metal electrodes combined with ceramic or wicking components as the base material. Ceramic atomizing coils are limited by the material molding process; the consistency of the pore size and porosity of the ceramic wicking component is often difficult to control consistently, resulting in variations in the wicking rate across different parts of the ceramic wicking component. This leads to inconsistent flavor profiles in the atomized aerosol. For atomizing coils using wicking components as the base material, assembling the rigid mesh electrode with the flexible wicking component is difficult and often requires manual work. This results in poor assembly precision and, similarly, inconsistent flavor profiles in the atomized aerosol. Summary of the Invention
[0003] This application provides a heating element that can solve the technical problem of poor taste consistency of aerosol generated by atomizing core.
[0004] To solve the above-mentioned technical problems, this application provides a heating element for the atomizing core of an atomizing device. The heating element is made of silicon-based material and is used to heat the atomizing matrix to generate an aerosol. The heating element includes a heating part, an electrode part, and a first reinforcing body. The electrode part is connected to the opposite ends of the first reinforcing body. The electrode part and the first reinforcing body surround a heating part mounting space. The heating part is installed in the heating part mounting space. The opposite ends of the heating part are electrically connected to the electrode part. A hollow area is provided between the heating part, the electrode part, and the first reinforcing body.
[0005] This application provides an atomizing core, including a heating element, an oil guide, and a base as described above. The base has openings at both ends, the oil guide is installed inside the base, and the heating element and the oil guide are spaced apart and opposite each other.
[0006] This application provides an atomizing component, including an atomizing core, an oil cup, a base, a bottom cover, and a conductive component as described above. The atomizing core is installed in the base, the base is housed in the oil cup, the bottom cover is placed on one end of the oil cup, and a conductive component is inserted into the bottom cover. The conductive component is electrically connected to the atomizing core.
[0007] This application also provides an atomizing device, including the atomizing components described above.
[0008] The heating element provided in this application is used as the atomizing core of an atomizing device. The heating element is made of silicon-based material and is suitable for processing using etching and physical vapor deposition processes. This ensures the precision of the atomizing core and is suitable for automated assembly of the atomizing core, resulting in high precision and stable quality of the atomizing core, which can improve the consistency of the taste of the aerosol generated by the atomizing core. In addition, hollow areas are provided between the heating part, the electrode part, and the first reinforcement, which reduces the area of the heating element and the contact area between the heating part and the electrode part. This reduces the heat conduction area of the heating part, which can improve the heat utilization rate of the heating element and improve the atomization effect. Attached Figure Description

[0026] This application provides a heating element for the atomizing core of an atomizing device. Please refer to [link / reference]. Figure 1 The heating element 10 is made of silicon-based material and is used to heat the atomizing matrix to generate an aerosol. The silicon-based material can be monocrystalline silicon or polycrystalline silicon. Silicon-based materials are suitable for processing using etching (plasma or solvent etching) and physical vapor deposition (PVD) processes. These processes allow for precise control of processing accuracy, resulting in high precision for the heating element 10. On one hand, the high-precision heating element 10 ensures the accuracy of the atomizing core; on the other hand, the silicon-based heating element 10 has sufficient rigidity, making it suitable for automated assembly of the atomizing core. Compared to manual assembly, the atomizing core exhibits better assembly consistency and higher quality stability. Therefore, using the silicon-based heating element 10 for the atomizing core ensures the precision and quality stability of the atomizing core, thereby improving the consistency of the taste of the aerosol generated by the atomizing core.
[0027] The heating element 10 may include a heating part 11, an electrode part 12, and a first reinforcing body 13. In operation, the heating part 11 has a high temperature and can heat the atomizing matrix to generate an aerosol. The electrode part 12 has contacts for connecting to conductive components, thereby providing electrical energy to the heating part 11. The electrode part 12 is connected to the opposite ends of the first reinforcing body 13, and the electrode part 12 and the first reinforcing body 13 enclose a heating part mounting space 14, within which the heating part 11 is installed. The heating part 11, made of silicon-based material, is typically thin, has low bending strength, and is brittle, making it prone to breakage during assembly. By setting the first reinforcing body 13 and the electrode part 12 to enclose the heating part mounting space 14, the overall integrity of the heating element 10 can be improved, its bending strength increased, and the heating part 11 prevented from breaking during assembly. The opposite ends of the heating part 11 are electrically connected to the electrode part 12, and hollow areas 15 are provided between the heating part 11, the electrode part 12, and the first reinforcing body 13. By providing a hollow area 15 between the heating part 11, the electrode part 12, and the first reinforcement 13, the area of the heating element 10 is reduced, and the contact area between the heating part 11 and the electrode part 12 is reduced. The hollow area 15 is filled with air, which is a poor conductor of heat, thus reducing the heat conduction area of the heating part 11 and improving the heat utilization rate of the heating element 10, thereby enhancing the atomization effect.
[0028] Please continue reading. Figure 1In one embodiment, the heating element 11 is an elongated strip shape, and the heating element 11 is distributed in a curved manner within the heating element mounting space 14. Setting the heating element 11 as an elongated strip shape reduces its area, making the heat more concentrated and improving the heat utilization rate of the heating element 10. The curved distribution of the heating element 11 results in a longer length compared to a straight line, and a larger and more uniform distribution range within the heating element mounting space 14. This allows for heating the atomizing matrix to generate aerosols in multiple areas of the heating element mounting space 14, making the atomizing matrix supply points more dispersed and ensuring the supply rate of the atomizing matrix.
[0029] To further enhance the overall integrity of the heating element 10, in one embodiment, such as Figure 2 As shown, the heating element 10 includes a second reinforcing body 16, which is spaced apart in the heating element mounting space 14. The second reinforcing body 16 is connected to the heating element 11 or between the heating element 11 and the first reinforcing body 13. That is, both ends of the second reinforcing body 16 are connected to the heating element 11 and the first reinforcing body 13 respectively, or both ends of the second reinforcing body 16 are connected to different positions of the heating element 11. By providing the second reinforcing body 16, the area of a single hollow area 15 is reduced. The second reinforcing body 16 provides support for the heating element 11, correspondingly reducing the free length of the heating element 11 and increasing the bending stiffness of the heating element 11, making the heating element 11 less prone to breakage.
[0030] The heating element 11 and electrode 12 can be formed by depositing a conductive coating on a silicon substrate using a PVD process, or they can be arranged in other ways, as long as the heating element 11 can heat the atomized matrix when energized. In one embodiment, at least the heating element 11 is made of conductive silicon. Understandably, other parts of the heating element 10, such as the electrode 12, the first reinforcement 13, and the second reinforcement 16, can also be made of conductive silicon, meaning the heating element 10 is integrally formed from a conductive material. Specifically, the conductive silicon material can be prepared by doping a single-crystal silicon or polycrystalline silicon substrate with metal atoms. The doped metal atoms can be one or more of copper, zinc, and manganese atoms. When the heating element 10 is integrally formed from a conductive silicon material, it is not necessary to deposit a conductive coating on the silicon substrate, simplifying the manufacturing process. It should be noted that the heating element 10 is made of conductive silicon, which makes the heating part 11, the electrode part 12 and the first reinforcement 13 all conductive. By adjusting the cross-sectional area of the three, the resistance of the heating part 11 is significantly greater than that of the electrode part 12 and the first reinforcement 13, so that the heat is still concentrated on the heating part 11.
[0031] When the atomizer core is in operation, the heating element 10 and the oil guide 20 are positioned opposite each other at an interval, such as... Figure 3As shown. The oil guide 20 adsorbs the atomizing matrix onto the heating element 10, and the atomizing matrix forms an oil film on the surface of the oil guide 20. In one embodiment, as... Figure 4 As shown, the thickness of the heating element 11 is less than the thickness of the first reinforcing body 13. The first reinforcing body 13 has a larger thickness, which can increase the overall strength of the heating element 10. If the thickness of the heating element 11 increases with the thickness of the first reinforcing body 13, the thickness of the heating element 11 may be too large, and the oil film may not be able to rise to the side of the heating element 11 away from the oil guide member 20, causing the heating element 11 to dry-burn on the side away from the oil guide member 20. By setting the thickness of the heating element 11 to be less than the thickness of the first reinforcing body 13, dry-burning of the heating element 11 on the side away from the oil guide member 20 can be prevented.
[0032] In some embodiments, the thickness of the heating element 11 is 0.01-0.1 mm, and the thickness of the first reinforcing body 13 is greater than 0.2 mm. If the thickness of the heating element 11 is less than 0.01 mm, the heating element 11 has low bending stiffness and is easily broken; if the thickness of the heating element 11 is too large, dry burning is likely to occur. Specifically, the thickness of the heating element 11 can be 0.01 mm, 0.02 mm, 0.03 mm, 0.04 mm, 0.05 mm, 0.06 mm, 0.07 mm, 0.08 mm, 0.09 mm, 0.1 mm, etc., and is not specifically limited here. Setting the thickness of the first reinforcing body 13 to be greater than 0.2 mm can enhance the overall bending stiffness of the heating element 10 and prevent the heating element 10 from breaking. Specifically, the thickness of the first reinforcing body 13 can be 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, etc.
[0033] Please continue reading. Figure 4In one embodiment, the heating element 11 is located at the middle position in the thickness direction of the first reinforcement 13. Since the thickness difference between the heating element 11 and the first reinforcement 13 is significant, if the heating element 11 and the side of the first reinforcement 13 away from the oil guide 20 are flush, the distance between the heating element 11 and the oil guide 20 will be too large, and the side of the heating element 11 away from the oil guide 20 may experience dry burning. If the heating element 11 and the side of the first reinforcement 13 close to the oil guide 20 are flush, it is inconvenient to control the distance between the heating element 11 and the oil guide 20, which may result in the distance between the heating element 11 and the oil guide 20 being too small. This could cause the heating element 11 to be encased in the oil film, leading to oil splattering and preventing the atomizing matrix from being fully atomized, thus generating bubbles. The heating element 11 is positioned at the center of the first reinforcing body 13 in the thickness direction, such that the first reinforcing body 13 protrudes from the heating element 11. When assembling the oil guide 20, the protruding first reinforcing body 13 can limit the distance between the heating element 11 and the oil guide 20 to prevent oil splattering or dry burning. For example, the distance between the heating element 11 and the oil guide 20 is 0.01-0.50 mm, such as 0.01 mm, 0.05 mm, 0.10 mm, 0.15 mm, 0.20 mm, 0.25 mm, 0.30 mm, 0.35 mm, 0.40 mm, 0.45 mm, or 0.50 mm.
[0034] This application provides an atomizing coil. Please refer to [link / reference]. Figure 5 , Figure 6 The atomizer core 100 may include a heating element 10, an oil guide 20, and a base 30. The base 30 has openings at both ends, and the oil guide 20 is installed within the base 30. The heating element 10 and the oil guide 20 are spaced apart and opposite each other. Understandably, the heating element 10 may be connected to the base 30, or the heating element 10 may be assembled within the base 30, making the atomizer core 100 a standalone module. This facilitates the overall assembly of the atomizer core 100 into an atomization assembly, thereby enhancing the versatility and applicability of the atomizer core 100.
[0035] The oil guide 20 is a porous medium used to transfer the atomizing matrix to the heating element 10. The oil guide 20 can be cotton fiber or porous ceramic.
[0036] In one embodiment, the base 30 has a protrusion 31 at one end near the heating element 10, such as... Figure 6 As shown, one side of the heating element 10 abuts against the protrusion 31. The protrusion 31 protrudes from the base 30, reducing the contact area between the heating element 10 and the base 30, thereby reducing the heat conduction area of the heating element 10 and improving the heat utilization rate of the atomizing core 100. In addition, by providing the protrusion 31 protruding from the base 30, the protrusion 31 can be used for the installation and positioning of the heating element 10 when assembling the oil guide 20, so as to limit the distance between the heating part 11 and the oil guide 20 and prevent oil splattering or dry burning.
[0037] This application provides an atomizing component. Please refer to [link / reference]. Figures 7-10 The atomizing assembly 300 may include the atomizing core 100, oil cup 310, base 320, bottom cover 330, and conductive element 340 as described above. The atomizing core 100 is installed in the base 320, which is housed in the oil cup 310. The bottom cover 330 is placed over one end of the oil cup 310, and the conductive element 340 is inserted into the bottom cover 330, electrically connected to the atomizing core 100. The oil cup 310 stores an atomizing matrix, which can be adsorbed into the atomizing core 100. The atomizing core 100 heats the atomizing matrix to generate an aerosol.
[0038] The oil cup 310 includes a suction nozzle 311 and an air passage tube 312. The suction nozzle 311 is connected to the end of the oil cup 310 away from the bottom cover 330, and one end of the air passage tube 312 is connected to the suction nozzle 311. The opposite end of the air passage tube 312 is mounted on the base 320.
[0039] Please see Figures 9-12 The base 320 has a mounting cavity 321 with an opening at one end facing the base 320. The atomizing core 100 is installed inside the mounting cavity 321, and there is a gap between the mounting cavity 321 and the inner wall of the oil cup 310. The base 320 has an oil inlet 322 and an air inlet 323, with the oil inlet 322 communicating with the mounting cavity 321. The atomizing matrix can be transferred to the atomizing core 100 through the oil inlet 322. The air inlet 323 extends through both opposite sides of the base 320 and is located between the mounting cavity 321 and the end of the air passage 312, communicating with the air passage 312. In operation, the aerosol generated by the atomizing core 100 heating the atomizing matrix flows through the gap between the mounting cavity 321 and the inner wall of the oil cup 310 towards the mouthpiece 311. The aerosol enters the air passage 312 through the air inlet 323 and reaches the mouthpiece 311.
[0040] The atomizing assembly 300 may further include an oil-absorbing cotton 350, a first seal 360, and a second seal 370. The first seal 360 seals between the oil cup 310, the base 320, and the air passage 312. The oil-absorbing cotton 350 is housed within the bottom cover 330, and the second seal 370 is installed between the oil cup 310 and the bottom cover 330. The oil-absorbing cotton 350 can absorb the atomizing matrix, thereby preventing leakage. The first seal 360 and the second seal 370 may be made of silicone. Silicone has good compressibility, allowing the first seal 360 and the second seal 370 to undergo elastic deformation after assembly, thereby improving the airtightness of the atomizing assembly 300.
[0041] This application provides an atomizing device. Please refer to [link / reference]. Figure 13The atomizing device 500 may include the atomizing component 300, the control component 510, and the power supply component 520 as described above. The control component 510 can control the connection or disconnection of the atomizing component 300 and the power supply component 520 according to the inhalation action, so as to control the atomizing component 300 to heat the atomizing substrate to generate an aerosol or stop heating. Specifically, when inhaling through the mouthpiece 311, the control component 510 senses the negative pressure in the atomizing device 500, and the control component 510 controls the atomizing component 300 to connect with the power supply component 520, and the atomizing core 100 heats the atomizing substrate to generate an aerosol; when inhalation stops, the control component 510 controls the atomizing component 300 to disconnect from the power supply component 520, and the atomizing core 100 stops heating the atomizing substrate.
[0042] The heating element, atomizing core, atomizing assembly, and atomizing device provided in this application have at least the following beneficial effects:
[0043] 1. The heating element 10 is made of silicon-based material, which can ensure the precision of the atomizing core and is suitable for the automated assembly of the atomizing core. This results in high precision and stable quality of the atomizing core, which can improve the consistency of the taste of the aerosol generated by the atomizing core. In addition, a hollow area 15 is provided between the heating part 11, the electrode part 12 and the first reinforcement 13, which reduces the area of the heating element 10 and the contact area between the heating part 11 and the electrode part 12. This can improve the heat utilization rate of the heating element 10, thereby improving the atomization effect.
[0044] 2. The first reinforcing body 13 and the electrode part 12 surround to form a heating part mounting space 14, which can improve the overall integrity of the heating element 10, improve the bending strength of the heating element 10, and prevent the heating part 11 from being broken during assembly.
[0045] 3. The heating element 10 includes a second reinforcing body 16, which reduces the area of a single hollow area 15 and increases the bending stiffness of the heating part 11, making the heating part 11 less likely to be broken.
[0046] 4. At least the heating element 11 is made of conductive silicon-based material, which eliminates the need to deposit a conductive coating on the silicon substrate, thus simplifying the processing technology.
[0047] 5. The thickness of the heating element 11 is less than the thickness of the first reinforcing body 13, which can prevent the heating element 11 from dry burning on the side away from the oil guide 20.
[0048] 6. The thickness of the heating element 11 is 0.01-0.1mm, which can prevent the heating element 11 from being broken and also prevent the heating element 11 from dry burning on the side away from the oil guide 20.
[0049] 7. The heating element 11 is located at the middle position in the thickness direction of the first reinforcing body 13, so that the first reinforcing body 13 protrudes from the heating element 11. The first reinforcing body 13 protruding from the heating element 11 can limit the distance between the heating element 11 and the oil guide 20 to prevent oil splattering or dry burning.
[0050] 8. A protrusion 31 is provided at one end of the base 30 near the heating element 10, which reduces the contact area between the heating element 10 and the base 30 and can improve the heat utilization rate of the atomizing core 100. In addition, the protrusion 31 can be used for the installation and positioning of the heating element 10 and control the distance between the heating part 11 and the oil guide 20 to prevent oil splattering or dry burning.
