Description

The present invention relates to the technical field of electronic atomizers, and in particular to a heating element, an atomizing core, an atomizing assembly and an atomizing device.

[Background technology]

The atomizer cores of existing atomizer devices include two categories: ceramic cores and cotton cores. Although the heating elements of the two types of atomizer cores have different shapes, they are all made of metal electrodes combined with ceramic or oil-conducting parts and other base materials to form the atomizer core. The ceramic atomizer core is subject to the material molding process. The consistency of the pore size and porosity of the ceramic oil-conducting element itself is often difficult to stably control, resulting in differences in the oil conduction rates of various parts of the ceramic oil-conducting element, resulting in a poor taste of the aerosol generated by the atomization of the atomizer core. For atomizer cores with oil-conducting parts as the base material, it is more difficult to assemble the rigid mesh core electrode and the flexible oil-conducting part, and it can only be done manually. The assembly accuracy is poor and the consistency is also poor, which will also result in a poor taste of the aerosol generated by the atomization of the atomizer core.

The present application provides a heating element for an atomizing core of an atomizing device. Referring to FIG. 1 , the heating element 10 is made of a silicon-based material, and the heating element 10 is used to heat the atomizing matrix to generate an aerosol. The silicon-based material may be monocrystalline silicon or polycrystalline silicon. The silicon-based material is suitable for processing by etching (plasma or solvent etching) and physical vapor deposition (PVD) and other processes, and the above processes can accurately control the processing accuracy, so that the processing accuracy of the heating element 10 is high. On the one hand, the high-precision heating element 10 is used for the atomizing core, which can ensure the accuracy of the atomizing core; on the other hand, the heating element 10 processed by the silicon-based material has sufficient rigidity and is suitable for the automated assembly of the atomizing core. Compared with manual operation, the assembly consistency of the atomizing core is good and the quality stability is high. Therefore, the heating element 10 processed by the silicon-based material is used for the atomizing core, which can ensure the accuracy and quality stability of the atomizing core, thereby improving the taste of the aerosol generated by the atomization of the atomizing core.

The heating element 10 may include a heating part 11, an electrode part 12 and a first reinforcement 13. In the working state, the heating part 11 has a relatively high temperature, and the heating part 11 can heat the atomized matrix to generate an aerosol. The electrode part 12 is provided with contacts for connecting to a conductive member, thereby providing electrical energy to the heating part 11. The electrode part 12 is connected to the opposite ends of the first reinforcement 13, and the electrode part 12 and the first reinforcement 13 are surrounded to form a heating part installation space 14, and the heating part 11 is installed in the heating part installation space 14. The heating part 11 made of silicon-based material is usually thin, has low flexural and bending strength, is brittle, and is easy to break during the assembly process. By providing the first reinforcement 13 and the electrode part 12 to surround the heating part installation space 14, the integrity of the heating element 10 can be improved, the bending strength of the heating element 10 can be improved, and the heating part 11 can be prevented from being broken during the assembly process. 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 reinforcement 13. By providing the hollow areas 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 areas 15 are filled with air, which is a poor conductor of heat, so that the heat conduction area of the heating part 11 becomes smaller, which can improve the heat utilization rate of the heating element 10, thereby improving the atomization effect.

Please continue to refer to FIG. 1. In one embodiment, the heating portion 11 is in the shape of an elongated strip, and the heating portion 11 is distributed in a curve in the heating portion installation space 14. The heating portion 11 is set in the shape of an elongated strip, which can reduce the area of the heating portion 11, so that the heat is more concentrated, and the heat utilization rate of the heating element 10 can be improved. The heating portion 11 distributed in a curve has a longer length than a straight line, and the distribution range in the heating portion installation space 14 is larger and more uniform. The atomized substrate can be heated in multiple areas of the heating portion installation space 14 to generate aerosol, so that the atomized substrate supply points are more dispersed to ensure the supply rate of the atomized substrate.

To further enhance the integrity of the heating element 10, in one embodiment, as shown in FIG. 2, the heating element 10 includes a second reinforcement 16, which is arranged at intervals in the heating portion installation space 14, and is connected to the heating portion 11 or between the heating portion 11 and the first reinforcement 13, that is, the two ends of the second reinforcement 16 are respectively connected to the heating portion 11 and the first reinforcement 13, or the two ends of the second reinforcement 16 are respectively connected to different positions of the heating portion 11. By providing the second reinforcement 16, the area of a single hollow area 15 is reduced, and the second reinforcement 16 provides support for the heating portion 11, correspondingly reducing the free length of the heating portion 11, increasing the bending rigidity of the heating portion 11, and making the heating portion 11 not easily broken.

The heating portion 11 and the electrode portion 12 may be deposited on a silicon-based substrate to form a conductive coating by a PVD process, or may be arranged in other ways, as long as the heating portion 11 can heat the atomized substrate when powered on. In one embodiment, at least the heating portion 11 is a conductive silicon-based material. It is understandable that other parts of the heating element 10, such as the electrode portion 12, the first reinforcement 13, and the second reinforcement 16 may also be conductive silicon-based materials, that is, the heating element 10 is integrally formed as a whole conductive material. Specifically, the conductive silicon-based material may be prepared by doping metal atoms with a monocrystalline silicon or polycrystalline silicon substrate. Among them, the doped metal atoms may be one or more of copper atoms, zinc atoms, and manganese atoms. When the heating element 10 is integrally formed as a conductive silicon-based material, it is not necessary to deposit a conductive coating on the silicon-based substrate, thereby simplifying the processing technology. It should be noted that the heating element 10 is made of a conductive silicon-based material, so that the heating part 11, the electrode part 12 and the first reinforcement 13 are all conductive. By adjusting the cross-sectional area between the three, the resistance value 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.

When the atomizer core is in working state, the heating element 10 and the oil guide member 20 are spaced apart and opposite to each other, as shown in FIG3 . The oil guide member 20 adsorbs the atomized matrix to the heating element 10, and the atomized matrix forms an oil film on the surface of the oil guide member 20 . In one embodiment, as shown in FIG4 , the thickness of the heating portion 11 is less than the thickness of the first reinforcement 13 . The first reinforcement 13 has a larger thickness, which can increase the overall strength of the heating element 10 . If the thickness of the heating portion 11 increases with the thickness of the first reinforcement 13 , the thickness of the heating portion 11 may be too large, and the oil film cannot climb to the side of the heating portion 11 away from the oil guide member 20 , resulting in dry burning of the heating portion 11 on the side away from the oil guide member 20 . By setting the thickness of the heating portion 11 to be less than the thickness of the first reinforcement 13 , the heating portion 11 can be prevented from being dry burned on the side away from the oil guide member 20 .

In some embodiments, the thickness of the heat generating portion 11 is 0.01-0.1 mm, and the thickness of the first reinforcement 13 is greater than 0.2 mm. If the thickness of the heating part 11 is less than 0.01mm, the thickness of the heating part 11 is small, the bending rigidity is low, and the heating part 11 is easy to be broken; if the thickness of the heating part 11 is too large, dry burning is easy to occur. Specifically, the thickness of the heating part 11 can be 0.01mm, 0.02mm, 0.03mm, 0.04mm, 0.05mm, 0.06mm, 0.07mm, 0.08mm, 0.09mm, 0.1mm, etc., which are not specifically limited here. Setting the thickness of the first reinforcement 13 to be greater than 0.2mm can enhance the overall bending rigidity of the heating element 10 and prevent the heating element 10 from being broken. Specifically, the thickness of the first reinforcement 13 can be 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, etc.

Please continue to refer to FIG. 4. In one embodiment, the heating part 11 is arranged in the middle position in the thickness direction of the first reinforcement 13. Since the thickness difference between the heating part 11 and the first reinforcement 13 is relatively large, if the heating part 11 is flush with the side of the first reinforcement 13 away from the oil guide 20, the distance between the heating part 11 and the oil guide 20 will be too large, and the heating part 11 may dry burn on the side away from the oil guide 20; if the heating part 11 is flush with the side of the first reinforcement 13 close to the oil guide 20, it is inconvenient to control the distance between the heating part 11 and the oil guide 20, and the distance between the heating part 11 and the oil guide 20 may be too small, and the heating part 11 is wrapped in the oil film, which will cause oil frying, resulting in the atomization matrix being unable to be fully atomized and generating bubbles. The heating part 11 is arranged at the middle position in the thickness direction of the first reinforcement 13, so that the first reinforcement 13 protrudes from the heating part 11. When the oil guide 20 is assembled, the first reinforcement 13 protruding from the heating part 11 can limit the distance between the heating part 11 and the oil guide 20 to prevent oil frying or dry burning. Exemplarily, the distance between the heating part 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.

The present application provides an atomizer core. Referring to Figures 5 and 6, the atomizer core 100 may include a heating element 10, an oil guide member 20, and a base 30. The base 30 is provided with openings at both ends, the oil guide member 20 is installed in the base 30, and the heating element 10 and the oil guide member 20 are spaced and opposite to each other. It can be understood that the heating element 10 can be connected to the base 30, or the heating element 10 can be assembled in the base 30, so that the atomizer core 100 becomes an independent module, which is convenient for assembling the atomizer core 100 as a whole into the atomizer assembly to enhance the versatility and applicability of the atomizer core 100.

The oil guide 20 is a porous medium, which is used to transfer the atomized matrix to the heating element 10. The oil guide 20 can be cotton fiber or porous ceramic.

In one embodiment, a protrusion 31 is provided at one end of the base 30 close to the heating element 10, as shown in FIG6 , and 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 atomizer core 100. In addition, by providing the protrusion 31 protruding from the base 30, when assembling the oil guide member 20, the protrusion 31 can be used for the installation and positioning of the heating element 10, so as to limit the distance between the heating portion 11 and the oil guide member 20, so as to prevent oil frying or dry burning.

The present application provides an atomizer assembly. Referring to FIGS. 7 to 10 , the atomizer assembly 300 may include the atomizer core 100, the oil cup 310, the base 320, the bottom cover 330, and the conductive member 340 as described above. The atomizer core 100 is installed in the base 320, the base 320 is accommodated in the oil cup 310, the bottom cover 330 is covered at one end of the oil cup 310, and the conductive member 340 is inserted on the bottom cover 330, and the conductive member 340 is electrically connected to the atomizer core 100. The oil cup 310 stores an atomization matrix, which can be adsorbed to the atomizer core 100, and the atomizer core 100 heats the atomization matrix to generate an aerosol.

The oil cup 310 includes a suction nozzle 311 and an airway pipe 312 . The suction nozzle 311 is connected to one end of the oil cup 310 away from the bottom cover 330 . One end of the airway pipe 312 is connected to the suction nozzle 311 . The opposite end of the airway pipe 312 is installed on the base 320 .

Please refer to Figures 9 to 12. The base 320 is provided with a mounting cavity 321. The mounting cavity 321 is provided with an opening at one end facing the base 320. The atomizer core 100 is installed in the mounting cavity 321. There is a gap between the mounting cavity 321 and the inner wall of the oil cup 310. The base 320 is provided with an oil inlet hole 322 and an air inlet hole 323. The oil inlet hole 322 is connected to the mounting cavity 321. The atomized matrix can be transferred to the atomizer core 100 from the oil inlet hole 322. The air inlet hole 323 runs through the two opposite sides of the base 320. The air inlet hole 323 is located between the mounting cavity 321 and the end of the airway tube 312. The air inlet hole 323 is connected to the airway tube 312. In the working state, the aerosol generated by the atomizing core 100 heating the atomizing matrix flows toward one end of the suction nozzle 311 through the gap between the mounting cavity 321 and the inner wall of the oil cup 310 , and the aerosol enters the airway tube 312 through the air inlet hole 323 and reaches the suction nozzle 311 .

The oil-absorbing cotton 350 can absorb the atomized matrix to prevent the atomized matrix from leaking. The first sealing member 360 and the second sealing member 370 can be made of silicone, which has good compressibility, so that the first sealing member 360 and the second sealing member 370 can be elastically deformed after assembly to improve the airtightness of the atomizing assembly 300.

The present application provides an atomization device. Referring to FIG. 13 , the atomization device 500 may include the atomization assembly 300, the control assembly 510, and the power assembly 520 as described above. The control assembly 510 may control the atomization assembly 300 to be connected or disconnected with the power assembly 520 according to the suction action, so as to control the atomization assembly 300 to heat the atomization matrix to generate an aerosol or stop heating. Specifically, when inhaling through the suction nozzle 311, the control assembly 510 senses the negative pressure in the atomization device 500, and the control assembly 510 controls the atomization assembly 300 to be connected with the power assembly 520, and the atomization core 100 heats the atomization matrix to generate an aerosol; when the inhalation stops, the control assembly 510 controls the atomization assembly 300 to be disconnected from the power assembly 520, and the atomization core 100 stops heating the atomization matrix.
