Description

Technical Field

[0001] The present application relates to the field of electronic cigarettes, and in particular to an anti-leakage oil atomization core for electronic cigarettes. Background Art

[0002] The electronic cigarette atomizer core is the core component of the electronic cigarette, responsible for transferring the e-liquid to the heating element, heating it and atomizing it, forming the smoke that the user inhales. As the e-cigarette market matures, the taste and mouthfeel of the e-cigarette have gradually become the core competitiveness of the product. After the safety assessment of the e-liquid components has been gradually improved, the use of a considerable part of the chemicals has been restricted. The adjustment of the atomizer core can make up for the taste and mouthfeel defects caused by the control of the e-liquid components to a certain extent, and determines the service life of the finished e-cigarette or the cartridge.

[0003] At present, the electronic cigarette atomization core on the market is usually composed of an alloy heating element, a porous oil-conducting material, a round tube bracket, and a heating element fixing seat. It is usually divided into two types according to the porous oil-conducting material: a cotton core and a ceramic core. After rapid development and verification in the market, the cotton core with multiple layers of spunlace non-woven fabrics and laminated die-cutting has gradually become the mainstream and trend of the market with its advantages of flexible adjustment, full taste, high degree of sweet taste restoration, and large amount of smoke. The spunlace non-woven fabric used in the cotton core has a fiber diameter ranging from 5um to 25um, and the capillary diameter constructed by it ranges from 10um to 700um. Through multi-layer superposition, when the oil is wetted, the pressure difference between the inside and outside of the oil tank generally reaches 150Pa, and then the air begins to slowly penetrate into the oil tank from the center hole. The heating mesh can usually only cover 2 / 3 of the area along the circumference at the center hole, and the remaining 1 / 3 of the area is generally the oil-conducting cotton seam area. The seam area is not supported by the heating mesh and is very easy to expand and deform, which will further reduce the air permeability pressure difference of the oil tank.

[0004] However, compared with the hard ceramic core, the cotton core also has disadvantages such as poor assembly stability, easy oil leakage, and easy burning. Especially in the oil-filled cigarette cartridges, there is a lack of oil storage cotton to restrain the fluidity of the oil. When the negative pressure in the oil tank is not enough and the airflow can easily penetrate from the atomization core, the oil can easily leak from the seams and edges of the oil-conducting cotton and even through the thorny pores of the oil-conducting cotton, which has caused great restrictions on the oil filling amount and user experience of the cigarette cartridges.

[0005] Therefore, without affecting the taste and oil conduction, it is an urgent need in the market technology to develop a strong sealing atomizer core that prevents oil leakage, increases the oil filling amount of the cartridge and the consumer experience. And with the increase of oil filling amount, it can also reduce the waste of whole cigarettes and cartridges, as well as the pressure on environmental emissions. Summary of the invention

[0013] A second gap is formed between the two ends of the heat-generating mesh, and the first gap is directly opposite to the second gap.

[0014] In at least one embodiment of the present application, the first oil-conducting cotton layer includes a plurality of guide layers arranged in parallel, and each of the guide layers is connected by pressing;

[0015] The second oil-conducting cotton layer comprises a transition layer and an atomizing layer which are arranged in sequence, the lipophilic and hydrophilic semipermeable membrane is arranged between the guide layer and the transition layer, and the heating mesh abuts against the inner surface of the atomizing layer.

[0016] In at least one embodiment of the present application, the heating mesh comprises a positive electrode pin, a negative electrode pin and a metal mesh, the positive electrode pin and the negative electrode pin are respectively arranged at the annular butt ends of the metal mesh, and a second gap is formed between the positive electrode pin and the negative electrode pin;

[0017] The atomizer core also includes a power supply component, and the output end of the power supply component is respectively connected to the positive electrode pin and the negative electrode pin, so as to make the metal mesh heat up.

[0018] In at least one embodiment of the present application, the atomizer core further comprises a sealing fixing seat, and the sealing fixing seat is attached to a side of the second oil-conducting cotton layer away from the lipophilic and hydrophilic semipermeable membrane;

[0019] The sealing fixing seat is located between the positive electrode pin and the negative electrode pin and blocks the first gap, and is used for supporting the second oil-conducting cotton layer when the second oil-conducting cotton layer expands along the side away from the lipophilic and hydrophilic semipermeable membrane.

[0020] In at least one embodiment of the present application, the sealing fixing seat includes an integrally formed fixing portion and a supporting portion, and opposite ends of the fixing portion abut against the positive electrode pin and the negative electrode pin respectively to support the heating mesh;

Even if the pressure in the oil tank is reduced, the micropores of the lipophilic and hydrophilic semipermeable membrane can block the entry of air, maintain the relative vacuum state in the oil tank, and prevent the oil in the oil tank from flowing out. The lipophilic and hydrophilic semipermeable membrane has selective permeability. Within the set negative pressure range of the oil tank, it only allows the oil to flow to the atomization area in one direction and does not allow the air to enter the oil tank in the opposite direction through the oil-conducting cotton.

[0030] Through the accurate matching of the atomizer tube opening and the sealing fixing seat, the direct oil leakage and oil leakage caused by the uncontrolled pressure difference caused by the sealing failure of the oil-conducting cotton and the first gap and the second gap of the heating element due to the collapse and deformation of the oil-conducting cotton are solved, thereby improving the reliability and consistency of the product; effectively simplifying the assembly process and materials of the atomizer core, reducing costs, compared with the existing atomizer cores of open oil filling, transparent oil tank, and oil core separation type cigarette cartridges, which usually require the structure of inner and outer atomizer tubes and multiple cotton wrapping, the present invention reduces one metal tube and one cotton wrapping process, and the comprehensive processing and material costs can be reduced by more than 40%.

[0045] The embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0046] It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a central component at the same time. When a component is considered to be "located on" another component, it may be directly located on the other component or there may be a central component at the same time.

[0047] The embodiment of the present application provides an anti-leakage electronic atomization core, which is placed in a smoke oil bin and is used to atomize smoke oil for a user to absorb, including:

[0048] The atomizing tube has an atomizing cavity and a smoke outlet connected to the atomizing cavity along its length, and an oil inlet hole connected to the smoke oil bin is formed on its side wall;

[0049] The oil-conducting cotton comprises a first oil-conducting cotton layer, a lipophilic and hydrophilic semipermeable membrane, and a second oil-conducting cotton layer which are sequentially arranged inward from the inner wall of the atomizing tube, the lipophilic and hydrophilic semipermeable membrane is provided with a first micropore, the pore size of the first micropore is a, wherein 10 μm≤a≤30 μm, and is used to fill the first micropore with the smoke oil when the smoke oil penetrates into the atomizing chamber through the first flow-conducting cotton;

[0050] The heating mesh is annularly arranged on the inner surface of the second oil-conducting cotton layer and is used for atomizing the e-liquid.

[0051] The above-mentioned anti-leakage electronic atomization core is provided with a lipophilic and hydrophilic semipermeable membrane and a first microporous structure in the oil-conducting cotton, so that it is difficult for external air to enter the oil tank through the lipophilic and hydrophilic semipermeable membrane, thereby avoiding the problem of oil leakage caused by the balance of air pressure in the oil tank and the external environment. Even if the pressure in the oil tank is reduced, the micropores of the lipophilic and hydrophilic semipermeable membrane can block the entry of air, maintain the relative sealing state in the oil tank, and prevent the oil in the oil tank from flowing out. The lipophilic and hydrophilic semipermeable membrane has selective permeability, allowing only oil to pass through but not air. In the process of oil penetrating into the atomization chamber through the first oil-conducting cotton layer, the micropores of the lipophilic and hydrophilic semipermeable membrane can effectively fill the oil, further improve the overall sealing effect of the atomization core, and prevent the oil from leaking in the non-atomized state. The multilayer structure design of the first oil-conducting cotton layer, the lipophilic and hydrophilic semipermeable membrane and the second oil-conducting cotton layer enables the oil to be effectively guided and controlled before entering the atomization chamber, reducing the risk of leakage due to the fluidity of the oil. Even during continuous use, the e-liquid in the tank can remain stable and will not flow out easily.

[0052] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0053] See also Figure 1-Figure 12 The embodiment of the present application provides an anti-leakage electronic atomization core 100, which is placed in a smoke oil bin and is used to atomize smoke oil for a user to absorb, including:

[0054] The atomizing tube 10 has an atomizing chamber 11 and a smoke outlet 12 and an air inlet 14 connected to the atomizing chamber 11 along its length, and an oil inlet hole 13 connected to the oil tank is formed on its side wall;

[0055] The oil-conducting cotton 20 comprises a second oil-conducting cotton layer 21, a lipophilic and hydrophilic semipermeable membrane 22 and a first oil-conducting cotton layer 23 which are sequentially arranged inward from the inner wall of the atomizing tube 10. The lipophilic and hydrophilic semipermeable membrane 22 is provided with a first micropore, and the pore size of the first micropore is a, wherein 10 μm≤a≤30 μm, and is used to fill the first micropore with the smoke oil when the smoke oil penetrates into the atomizing chamber 11 through the first flow-conducting cotton;

[0056] The heating mesh 30 is annularly arranged on the inner surface of the first oil-conducting cotton layer 23 and is used for atomizing the tobacco oil.

[0057] Specifically, the atomizer tube 10 is the main structure of the entire atomizer core, providing a sealed cavity for atomization of the smoke oil. The air inlet 14 is connected to the external environment, and the smoke outlet 12 is used to guide the atomized smoke for the user to inhale. The oil inlet hole 13 is used to connect the smoke oil tank to guide the smoke oil into the atomization cavity 11. The second oil guide cotton layer 21 serves as the primary structure of the oil guide cotton 20, absorbing and guiding the smoke oil from the oil inlet hole 13 into the atomization cavity 11. Ensure that the smoke oil can be evenly distributed and transferred to the inner layer, thereby improving the oil guide efficiency.

[0058] Furthermore, the lipophilic and hydrophilic semipermeable membrane 22 has a microporous structure, which only allows the smoke oil to pass through and blocks the air. The flow of the smoke oil is controlled to prevent the air from passing through and maintain the internal pressure stable. Through the design of the micropores, the smoke oil can be effectively filled to prevent oil leakage, while preventing the outside air from entering, maintaining the sealed state in the atomization chamber 11, and preventing the oil leakage caused by the pressure difference. The first oil-conducting cotton layer 23 further guides the oil and contacts the heating mesh 30 to ensure that the smoke oil can be fully atomized. Finally, the smoke oil is guided to the heating mesh 30. Providing a stable supply of smoke oil enables the heating mesh 30 to work efficiently and ensure that the smoke oil is fully atomized.

[0059] Furthermore, by setting the micropores to a size of 10 μm to 30 μm, it can be ensured that after the e-liquid penetrates into the lipophilic and hydrophilic semipermeable membrane 22, the e-liquid fills the micropores of the lipophilic and hydrophilic semipermeable membrane 22. The molecular tension between the e-liquids and the small pore size can effectively prevent air from entering, preventing external air from entering the atomization chamber 11 through the lipophilic and hydrophilic semipermeable membrane 22.

[0060] The smoke oil enters the atomizing tube 10 through the oil inlet hole 13 and is absorbed by the second oil-conducting cotton layer 21. The second oil-conducting cotton layer 21 guides the smoke oil to the lipophilic and hydrophilic semipermeable membrane 22, and the smoke oil passes through the micropores on the lipophilic and hydrophilic semipermeable membrane 22 and is further absorbed by the first oil-conducting cotton layer 23. The first oil-conducting cotton layer 23 guides the smoke oil to the heating mesh 30, and the heating mesh 30 heats the smoke oil and atomizes it into smoke. The atomized smoke is discharged through the smoke outlet 12 for the user to inhale.

[0061] In a specific embodiment, the second oil-conducting cotton layer 21, the lipophilic and hydrophilic semipermeable membrane 22 and the first oil-conducting cotton layer 23 are all annularly arranged in the atomizing chamber 11, and the side of the second oil-conducting cotton layer 21 away from the lipophilic and hydrophilic semipermeable membrane 22 is attached to the atomizing tube 10;

[0062] The second oil-conducting cotton layer 21, the lipophilic and hydrophilic semipermeable membrane 22 and the first oil-conducting cotton layer 23 are all provided with a first end and a second end butted in an annular manner, and a first gap 24 is formed between the first end and the second end;

[0063] A second gap 34 is formed between the two ends of the heat generating mesh 30 , and the first gap 24 is directly opposite to the second gap 34 .

[0064] Specifically, the annular oil-conducting cotton 20 structure can be evenly distributed in the atomization chamber 11, ensuring that the smoke oil can be evenly absorbed and guided to the atomization area. The annular oil-conducting cotton 20 is a whole layer of oil-conducting cotton 20 that is bent and tightly fitted with the atomization tube, and the two ends of the oil-conducting cotton 20 abut against each other to form a ring. The second oil-conducting cotton layer 21 fits the inner wall of the atomization tube 10, increasing the stability and sealing of the oil-conducting cotton 20. The annular design enables the oil-conducting cotton 20 to fully contact the smoke oil, and the annular structure helps to improve the oil-conducting efficiency, ensuring that the atomization core can work effectively at different angles. In addition, the fit between the second oil-conducting cotton layer 21 and the inner wall of the atomization tube 10 enhances the stability of the oil-conducting cotton 20.

[0065] Furthermore, since the heating mesh 30 needs to generate heat to connect to the power supply, the two poles cannot be connected and there is a gap. In addition to generating heat, the heating mesh 30 also has the function of supporting the oil-conducting cotton 20. In order to prevent the oil-conducting cotton 20 from having parts that cannot be supported and the phenomenon that the oil-conducting cotton 20 cannot be heated and atomized after being infiltrated by the e-liquid, the oil-conducting cotton 20 is also arranged to have a first gap 24 corresponding to the second gap 34.

[0066] Furthermore, the first gap 24 is directly opposite to the second gap 34, which can prevent the heating mesh 30 from maximally increasing the supporting effect on the oil-conducting cotton 20, and can heat and atomize the smoke oil that penetrates from the oil-conducting cotton 20 to the maximum extent, preventing oil leakage caused by incomplete atomization.

[0067] In a specific embodiment, the heating mesh 30 includes a positive electrode pin 31, a negative electrode pin 32 and a metal mesh 33, the positive electrode pin 31 and the negative electrode pin 32 are respectively arranged at the annular butt ends of the metal mesh 33, and a second gap 34 is formed between the positive electrode pin 31 and the negative electrode pin 32.

[0068] Specifically, the positive electrode pin 31 and the negative electrode pin 32 are connected to the positive electrode and the negative electrode of the power supply respectively, and the metal mesh 33 generates heat after power is supplied between the two electrodes, and is used to heat and atomize the e-liquid. By designing the heating mesh 30 to be composed of the positive electrode pin 31, the negative electrode pin 32 and the metal mesh 33, the structure is simple and the function is clear, and the electrical energy can be effectively converted into thermal energy, and the e-liquid can be heated for atomization, thereby ensuring the normal operation of the electronic cigarette.

[0069] Furthermore, the positive electrode pin 31 and the negative electrode pin 32 are arranged at the annular butt end of the metal mesh 33 to ensure that the current passes through the entire mesh and uniformly heats the metal mesh 33. The arrangement positions of the positive electrode pin 31 and the negative electrode pin 32 ensure that the current can pass through the entire metal mesh 33 uniformly, thereby achieving uniform heating. This design avoids the problem of local overheating or uneven temperature, ensures that the e-liquid is uniformly atomized on the entire heating mesh, and improves the atomization effect and user experience.

[0070] Furthermore, the gap design makes the installation and power connection of the heating mesh 30 more convenient, and also avoids the short circuit problem between the electrodes. The existence of the gap also ensures that the heating mesh 30 can work stably after power is turned on, and will not cause local overheating or burning due to the small distance between the electrodes.

[0071] In summary, this design ensures uniform heating and stable operation of the heating mesh 30 by setting the positive electrode pin 31 and the negative electrode pin 32 at the annular butt end of the metal mesh 33 and forming a gap between the two poles. Combined with the design of the oil guide cotton 20, the smoke oil can be effectively guided to the heating mesh 30 to ensure sufficient atomization of the smoke oil. This structure not only improves the atomization effect, but also reduces the oil leakage problem.

[0072] In a specific embodiment, the atomizer core further includes a power supply assembly (not shown), and the output end of the power supply assembly is respectively connected to the positive electrode pin 31 and the negative electrode pin 32 for heating the metal mesh 33 .

[0073] Specifically, the power supply component is the power source of the entire atomizer core, providing power to the positive pin 31 and the negative pin 32 to heat the metal mesh 33. By setting up the power supply component, stable power can be provided to the atomizer core to ensure that the metal mesh 33 can continue to heat up, thereby realizing the function of continuous atomization. At the same time, the independent power supply component design is easy to maintain and replace, which improves the service life and reliability of the atomizer core. The metal mesh 33 can be quickly heated when the current passes through it, and the heat is evenly distributed, so that the smoke oil can be quickly atomized on the metal mesh 33. This design improves the efficiency and effect of atomization, ensuring that users can get a good smoking experience.

[0074] In a specific embodiment, the atomizer core further includes a first sealing fixing seat 50, and the first sealing fixing seat 50 is attached to a side of the first oil-conducting cotton layer 23 away from the lipophilic and hydrophilic semipermeable membrane 22;

[0075] The first sealing fixing seat 50 is located between the positive electrode pin 31 and the negative electrode pin 32 and blocks the first gap 24 , and is used to support the first oil-conducting cotton layer 23 when the first oil-conducting cotton layer 23 expands along the side away from the lipophilic and hydrophilic semipermeable membrane 22 .

[0076] Specifically, the first sealing fixing seat 50 is used to provide structural support while ensuring electrical insulation between circuits to avoid short circuits. While providing mechanical support, the first sealing fixing seat 50 also plays a role in electrical isolation, preventing the current short circuit between the positive pin 31 and the negative pin 32, thereby improving the safety and reliability of the atomizer core. The first sealing fixing seat 50 is attached to the back of the first oil-conducting cotton layer 23 to provide additional support to prevent the first oil-conducting cotton layer 23 from collapsing inward when it expands. It ensures that the oil-conducting cotton layer can maintain its shape and position when it expands after absorbing the smoke oil, thereby maintaining a stable oil-conducting and atomization effect. The influence of the deformation of the oil-conducting cotton layer on the atomization effect is avoided.

[0077] Furthermore, the first sealing fixing seat 50 is located between the positive electrode pin 31 and the negative electrode pin 32, and blocks the first gap 24 to prevent leakage and collapse of the oil-conducting cotton layer at the gap. The first sealing fixing seat 50 can not only provide mechanical support, but also effectively block the first gap 24 of the oil-conducting cotton layer to prevent the smoke oil from leaking through the gap. The overall sealing and atomization effect of the atomizer core are ensured. When the first oil-conducting cotton layer 23 absorbs the smoke oil and expands, the first sealing fixing seat 50 provides the necessary support to prevent the oil-conducting cotton layer from deforming due to expansion. This support structure ensures the stability of the oil-conducting cotton layer after absorbing the smoke oil, and avoids the expansion affecting the atomization effect. At the same time, the setting of the first sealing fixing seat 50 improves the service life and performance stability of the atomizer core.

[0078] In a specific embodiment, both ends of the first sealing fixing seat 50 are respectively interference fit with the positive electrode pin 31 and the negative electrode pin 32, so as to prevent the heating mesh 30 from deforming when the first oil-conducting cotton layer 23 expands along the side away from the lipophilic and hydrophilic semipermeable membrane 22.

[0079] Specifically, the interference fit ensures a tight connection between the first sealing fixing seat 50 and the positive and negative electrode pins 32, preventing the support from loosening or falling off due to vibration during the use of the device. The long-term stability and reliability of the electronic cigarette atomizer core is ensured, and the performance degradation or failure of the electronic cigarette caused by loose connection is avoided.

[0080] Furthermore, the first sealing fixing seat 50 is fastened to the positive and negative electrode pins 32 by an interference fit. When the first oil-conducting cotton layer 23 expands, the support member provides a stable support structure to prevent the oil-conducting cotton layer from collapsing inward, thereby preventing the heating mesh 30 from being distorted or deformed due to the deformation of the oil-conducting cotton layer. This design ensures that the heating mesh 30 can maintain a stable shape and position during the heating process, thereby ensuring the effective atomization and uniform heating of the smoke oil. At the same time, it avoids the reduction of atomization effect or equipment performance caused by the deformation of the heating mesh 30. When the oil-conducting cotton 20 has a tendency to expand after absorbing oil, the heating mesh 30 will also have a tendency to deform inward. The support layer fits the oil absorption layer and can abut the positive electrode pin 31 and the negative electrode pin 32, and the heating mesh 30 will support the engagement more tightly.

[0081] In a specific embodiment, the insulating support layer is plastic or ceramic.

[0082] Specifically, the plastic or ceramic material has good electrical insulation properties, can effectively isolate and protect the circuits and electronic components in the electronic cigarette atomizer core, and prevent short circuits or damage to electronic components. The plastic or ceramic material has a certain mechanical strength and hardness, can stably support the first oil-conducting cotton layer 23, maintain stability when it expands, and prevent deformation or collapse of the oil-conducting cotton layer. Plastic or ceramic materials usually have good corrosion resistance and can maintain stable physical and electrical properties under various environmental conditions.

[0083] In summary, the electronic cigarette power supply component provides power to the heating mesh 30 through the positive and negative pins 32 and starts heating. The smoke oil penetrates into the first oil-conducting cotton layer 23 through the second oil-conducting cotton layer 21 and the lipophilic and hydrophilic semipermeable membrane 22. The first oil-conducting cotton layer 23 begins to expand after absorbing the smoke oil, and the insulating support layer, as a plastic or ceramic material, stably supports the oil-conducting cotton layer. The heating mesh 30 is heated by the current to atomize the smoke oil. The plastic or ceramic insulating support layer ensures the safe operation of the internal circuit of the electronic cigarette and avoids safety risks caused by electrical failures.

[0084] In a specific embodiment, the direction from the first gap 24 and the second gap 34 facing the atomizer tube 10 is defined as a first direction, the projection of the first gap 24 and the second gap 34 on the atomizer tube 10 along the first direction is a first area 60, and the oil inlet hole 13 is staggered from the first area 60.

[0085] Specifically, the projection of the first gap 24 and the second gap 34 on the atomizer tube 10 is divided into the first area 60, which helps to optimize the design and layout, and ensure that the space around the atomizer tube 10 of each component is reasonably utilized and does not overlap. By staggering the oil inlet holes 13, it is ensured that the oil inlet holes 13 will not be located in the first area 60, avoiding any interference or obstruction in the flow and atomization process of the smoke oil. The staggered setting of the oil inlet holes 13 helps to optimize the flow path and speed of the smoke oil, and ensure that the smoke oil can effectively and evenly enter the oil guide cotton 20. By preventing the oil inlet holes 13 from being directly located in the first area 60, the smoke oil in the oil tank directly enters the gap and causes leakage.

[0086] In a specific embodiment, the oil inlet hole 13 has at least one;

[0087] When there are two or more oil inlet holes 13 , the central axes of the oil inlet holes 13 intersect on the same plane.

[0088] Specifically, the oil inlet 13 serves as a passage for the smoke oil to enter the atomizer core, ensuring a continuous supply of smoke oil during the atomization process. Through a single oil inlet 13, the flow rate and speed of the smoke oil can be more accurately controlled to meet different usage requirements and atomization effects.

[0089] Furthermore, the central axes of the multiple oil inlet holes 13 intersect in the same plane, which helps to ensure that the smoke oil can flow into the atomization chamber 11 evenly, avoid the situation where there is too much or too little oil in some parts, and improve the uniformity and stability of atomization. Through multiple oil inlet holes 13, the fluidity of the smoke oil can be enhanced, so that it can be transmitted to the atomization chamber 11 more quickly and evenly, and the response speed and efficiency of the electronic cigarette can be improved.

[0090] In a specific embodiment, the second oil-conducting cotton layer 21 includes a plurality of guide layers 211 arranged in parallel, and each of the guide layers 211 is connected by pressing;

[0091] The first oil-conducting cotton layer 23 includes a transition layer 232 and an atomizing layer 231 which are sequentially arranged. The lipophilic and hydrophilic semipermeable membrane is arranged between the guide layer 211 and the transition layer 232 . The heating mesh 30 abuts against the inner surface of the atomizing layer 231 .

[0092] Specifically, the multi-layer flow-guiding structure can more effectively absorb and conduct the smoke oil, ensuring that the smoke oil can evenly penetrate into the atomization core, avoiding uneven supply or excessive penetration of the smoke oil. The transition layer 232 is located between the lipophilic and hydrophilic semipermeable membrane and the atomization layer 231, and its main function is to adjust the fluidity and stability of the smoke oil. The transition layer 232 provides a buffer for the smoke oil to enter the atomization layer 231, ensuring that the smoke oil can be evenly distributed on the surface of the atomization layer 231, avoiding the oil from entering the atomization area too quickly or too slowly, and ensuring the stability of the atomization process. The atomization layer 231 is close to the heating mesh 30 and directly contacts the heating element, so that the smoke oil is fully atomized at an appropriate temperature.

[0093] Furthermore, the guide area is equipped with two to five layers according to the thickness requirements, and the e-liquid is conducted through the capillary structure and fiber affinity of the lipophilic and hydrophilic semipermeable membrane and the oil-conducting cotton 20, and a higher airflow barrier is established when the first micropore is wetted, preventing the gas in the atomization chamber 11 from entering the oil tank through the atomization chamber 11, and the lipophilic and hydrophilic semipermeable membrane makes the air permeability pressure difference of the guide layer 211 after the e-liquid is wetted increase by more than 1 times compared with the transition layer 232, thereby avoiding the problem of insufficient negative pressure and oil leakage caused by airflow passing through the atomization core into the oil tank.

[0094] In a specific embodiment, the first sealing fixing seat 50 includes an integrally formed fixing portion 51 and a supporting portion 52, and opposite ends of the fixing portion 51 respectively abut against the positive electrode pin 31 and the negative electrode pin 32 to support the heating mesh 30;

[0095] The support portion 52 is annularly disposed at one end of the oil-conducting cotton 20 close to the power supply assembly 40 to support the oil-conducting cotton 20 .

[0096] Specifically, by fixing the positive electrode pin 31 and the negative electrode pin 32 of the heating mesh 30, the fixing part 51 can ensure that the heating mesh 30 does not move or have poor contact during operation. When the oil-conducting cotton expands after absorbing the e-liquid, the fixing part 51 can support the heating mesh 30, prevent the expansion of the oil-conducting cotton absorbing the e-liquid from affecting the deformation of the heating mesh 30, and can support the gap area between the positive and negative metal rods.

[0097] Furthermore, by fixing the oil-conducting cotton 20, the support portion 52 can avoid oil leakage caused by the position offset of the oil-conducting cotton 20. The offset of the oil-conducting cotton 20 may prevent the smoke oil from being normally transferred to the heating mesh 30, resulting in uneven oil supply or interrupted oil supply. The fixing effect ensures that the smoke oil is continuously and stably transferred to the atomization chamber 11, avoiding the oil supply problem from affecting the atomization effect. The stable position of the oil-conducting cotton 20 can ensure that the penetration rate of the smoke oil through the oil-conducting cotton layer remains consistent, thereby improving the working efficiency of the atomization core. Especially when used for a long time or working at high power, the stability of the oil-conducting cotton 20 is directly related to the uniformity and durability of the atomization effect. During the assembly process of the atomization core, the design of the support portion 52 also helps to avoid misalignment or tilting of the oil-conducting cotton 20, thereby reducing assembly errors.

[0098] The first sealing fixing seat 50 is made of a material with a softening point higher than 120°C and has good insulation performance. The softening point is above 120°C to ensure that the first sealing fixing seat 50 will not deform or fail in a high temperature environment, and is particularly suitable for applications near heating components; and the material has insulation properties to prevent safety hazards caused by electrical short circuits or leakage; the high strength characteristics of materials such as ceramics or glass further enhance the compression resistance of the sealing fixing seat, especially providing reliable support when the oil-conducting cotton 20 expands and generates pressure.

[0099] In a specific embodiment, the first sealing fixing seat 50 further includes a protrusion 53, and the fast fixing portion 51 extends outwardly from a side facing the oil-conducting cotton to form the protrusion 53, and the protrusion 53 extends into the first gap 24 to abut the first end and the second end.

[0100] Specifically, the first gap 24 is formed between the first end and the second end of the oil-conducting cotton layer, and the protrusion 53 extends into the gap to play a contact role. Its main function is to limit the end of the oil-conducting cotton layer so that it will not be dislocated or shifted due to expansion or external force during use. This structural design effectively ensures the relative stability of the oil-conducting cotton layer.

[0101] Furthermore, the protrusion 53 abuts against both ends of the oil-conducting cotton layer, which is equivalent to a structural limit to prevent the oil-conducting cotton layer from being displaced laterally or longitudinally due to expansion, contraction or external stress. During the expansion of the oil-conducting cotton layer due to the penetration of tobacco oil, the support of the protrusion 53 can effectively suppress excessive expansion and ensure the stability of the entire oil-conducting system.

[0102] In a specific embodiment, the atomizer core further includes a second sealing fixing seat 70, which is disposed at one end of the atomizer tube 10 and is disposed opposite to the first sealing fixing seat 50;

[0103] The second sealing fixing seat 70 has an inclined surface on one side close to the first sealing ring 50 . The inclined surface abuts against the supporting portion 52 to support the first sealing seat 50 .

[0104] Specifically, a first sealing fixing seat 50 and a second sealing fixing seat 70 are respectively provided at both ends of the atomizer tube 10. When the first sealing fixing seat 50 is set at a position away from the pins of the heating mesh 30, the second sealing fixing seat 70 is installed. The second fixing groove annularly opened on the second sealing fixing seat can fix the positive and negative pins of the heating mesh 30. The first sealing fixing seat supports the oil-conducting cotton, and the second sealing fixing seat 70 is bidirectionally fixed to be arranged opposite to the first sealing fixing seat 50.

[0105] Furthermore, the inclined surface provided on the second sealing fixing seat 70 abuts against the supporting portion 52 of the first sealing fixing seat 50, forming a complete fixing system at both ends of the atomizer core, which can better maintain the stability of the atomizer core. The first sealing fixing seat 50 and the second sealing fixing seat 70 can be assembled in reverse directions, which simplifies the assembly process and enables easier and more efficient assembly.
