Therefore, the features limited by “first”, “second” can explicitly or implicitly include at least one of the features. In addition, the technical solutions of various embodiments can be combined with each other, but it must be based on the fact that the technical solutions can be realized by those skilled in the art. When the combination of technical solutions appears to be contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the scope of protection claimed by the present application.

[0032] The application provides an atomization assembly applied to an electronic atomization device, which has high heating efficiency, high atomization efficiency and good atomization effect, and can always heat the air flow during use, so that the temperature of the air flow is not easily attenuated, the taste of smoke is better, and the product use experience is better.

[0033] Referring to FIGS. 1-4, the atomization assembly comprises a bracket assembly 1, a heating body 2, a first electrode 3 and a second electrode 4, wherein the bracket assembly 1 is provided with an air inlet 131, an air outlet 111 and an atomization air duct 141, the air inlet 131 and the air outlet 111 are communicated with the atomization air duct 141, and an air inlet channel 15 is formed between the air inlet 131 and the atomization air duct 141. The heating region of the heating body 2 is arranged in the atomization channel, the first electrode 3 and the second electrode 4 are arranged in the bracket assembly 1, parts of the first electrode 3 and the second electrode 4 extend into the atomization air duct 141, and are fixedly connected with and electrically connected with the heating body 2, the first electrode 3 and the second electrode 4 are sequentially distributed along the air flow direction of the atomization air duct 141, and the first electrode 3 is located in the air inlet channel 15.

[0034] Based on the above scheme, by arranging the first electrode 3 and the second electrode 4 in the atomization air duct 141, and arranging the first electrode 3 in the air inlet channel 15, compared with the prior art in which the electrodes are arranged on both sides of the atomization air duct 141, the connection point position of the electrodes and the heating body 2 is changed, the first electrode 3 and the second electrode 4 are closer to the heating region of the heating body 2, the circuit distance of the first electrode 3 and the second electrode 4 to the heating region of the heating body 2 is shorter, that is, the current path to the heating region of the heating body 2 is shorter, heat loss is reduced, the heating power of the heating region of the heating body 2 is improved, and the atomization efficiency and effect are improved.

[0035] The first electrode 3 and the second electrode 4 can absorb the heat transferred by the heating body 2, and in the smoking process, since the first electrode 3 is arranged in the air inlet channel 15, the first electrode 3 heats the air flow for the first time when the air flow passes through the air inlet channel 15, then the heating region of the heating body 2 heats the air flow for the second time, and the second electrode 4 heats the air flow for the third time, so that the temperature of the air flow is not easily attenuated, the taste of smoke is better, the user's smoking experience is greatly improved, and the use performance of the atomization assembly is improved.

[0036] In addition, the structure of the heating element 2 is optimized, and the structure of the heating element 2 across the atomization air channel 141 is reduced, so that the structure of the heating element 2 is simpler, which helps to reduce the cost; the first electrode 3 and the second electrode 4 are partially across the atomization air channel 141, and also play a role in piercing the oil bubble, have a double piercing oil bubble function, and are more conducive to the flow of the airflow. The first electrode 3 and the second electrode 4 also hinder the flow of the fluid, so that the fluid forms a vortex, and the aerosol in the atomization air channel 141 can re-aggregate, and it is easy to produce large-particle smoke after collision and aggregation, which helps to improve the smoke taste and improve the smoking experience of the user.

[0037] The first electrode 3 and the second electrode 4 can absorb part of the heat transferred by the heating area of the heating element 2, and the distance between the first electrode 3 and the second electrode 4 and the heating area is close. The first electrode 3 and the second electrode 4 can quickly absorb the heat of the heating area, and the first electrode 3 and the second electrode 4 can conduct heat and cool down, which plays a role in rapid heat dissipation, effectively reduces the possibility that the heat of the heating wire cannot be dissipated when the user continuously smokes, and prevents the temperature of the heating area from being too high.

[0038] Referring to FIGS. 1-6, in some embodiments, the first electrode 3 and the second electrode 4 are both across the atomization air channel 141, and at least one of the first electrode 3 and the second electrode 4 is located at the middle position of the cross section of the atomization air channel 141, and the heating area of the heating element 2 is located between the first electrode 3 and the second electrode 4.

[0039] When at least one of the first electrode 3 and the second electrode 4 is located at the middle position of the cross section of the atomization air channel 141, the projection view of the first electrode 3 and the second electrode 4 is arranged in a staggered manner, for example, the projection view of the first electrode 3 can fall on the middle position of the cross section of the atomization air channel 141; the first electrode 3 can divide the cross section of the atomization air channel 141 into two parts, or the projection view of the second electrode 4 can fall on the middle position of the cross section of the atomization air channel 141, and the second electrode 4 can divide the cross section of the atomization air channel 141 into two parts; to ensure that the projection view of at least one electrode can fall on the middle position of the cross section of the atomization air channel 141.

[0040] In the above embodiments, the first electrode 3 and the second electrode 4 can be distributed along the specific extension direction of the atomization air channel 141, which helps to improve the uniformity of heat conduction to the airflow, improve the smoke taste, and also fully pierce the oil bubble, improve the piercing oil bubble effect, and facilitate the flow of the airflow.

[0041] In addition, the first electrode 3 and the second electrode 4 are arranged in a staggered manner, which can further strengthen the strength of the airflow vortex and improve the taste of the smoke.

[0042] In some embodiments, the first electrode 3 and the second electrode 4 can also be located at the middle position of the cross section of the atomization air channel 141, the projection view of the first electrode 3 and the second electrode 4 coincide with each other, and the projection view of the first electrode 3 and the second electrode 4 falls on the middle position of the cross section of the atomization air channel 141, that is, the projection view of the first electrode 3 and the second electrode 4 can divide the cross section of the atomization air channel 141 into two parts. In this way, the first electrode 3 and the second electrode 4 can ensure the stability of the airflow, and also provide stable support for the heating body 2. When the heating body 2 is in close contact with the oil guiding cotton and other structures, the overall force of the heating body 2 is uniform, which can effectively prevent the heating body 2 from being deformed, improve the stability of the structure connection between the first electrode 3 and the second electrode 4 and the heating body 2, and improve the atomization effect and efficiency of the heating body 2 on the atomized liquid.

[0043] In the embodiments of the present application, the first electrode 3 and the second electrode 4 are located at the middle position of the cross section of the atomization air channel 141, which is only an example and does not limit the position of the first electrode 3 and the second electrode 4 in the atomization air channel 141.

[0044] In some embodiments of the present application, the first electrode 3 is arranged close to the air inlet 131, and the second electrode 4 is arranged close to the air outlet 111. In this way, when smoking, the first electrode 3 can quickly heat the airflow, so that the airflow entering the atomization air channel 141 will not affect the temperature in the atomization air channel 141, ensuring the stability of the airflow temperature, and the second electrode 4 further heats the airflow, so that the taste of the smoke discharged from the air outlet 111 is better, so as to improve the taste of the smoke and improve the user experience.

[0045] In work, the heating area of the heating body 2 has a first temperature, the first electrode 3 has a second temperature, and the second electrode 4 has a third temperature. The second temperature and the third temperature are both less than the first temperature, and the second temperature is less than the third temperature. The first temperature, the second temperature and the third temperature are all greater than room temperature.

[0046] When the external cold air enters the air inlet channel 15, it will reduce the temperature of the first electrode 3 to a certain extent. The first electrode 3 uses its own temperature to maintain the heating of the cold airflow, avoiding the temperature of the cold airflow entering the atomization air channel 141 being too low. In this way, by setting the temperature difference between the first electrode 3 and the second electrode 4, the temperature is reasonably distributed, and the design is reasonable. Even in cold environments, the atomization assembly can still maintain stable heating of the cold airflow, ensure the atomization effect and efficiency, and thus better improve the applicability of the atomization assembly.

[0047] Referring to FIGS. 2-6, in some embodiments, the heating body 2 includes a first support section 21, a second support section 22, and a heating section 23, the first support section 21 and the second support section 22 are arranged in a spaced manner, one end of the heating section 23 is connected with the first support section 21, and the other end is connected with the second support section 22, the first electrode 3 is fixedly connected with the first support section 21, and the second electrode 4 is fixedly connected with the second support section 22.

[0048] In the prior art, only the electric poles arranged on both sides of the air passage can support the heating wire structure, and the support force on the heating area is low. In the embodiments of the present application, the first electrode 3 and the second electrode 4 are arranged in the atomization air passage 141, the distance between the first electrode 3 and the second electrode 4 and the heating area is short, and the first electrode 3 and the second electrode 4 can provide stable support force for the heating body 2 and the heating area, effectively enhance the strength of the heating body 2, and make the structure of the heating area of the heating body 2 not easy to be concave and deformed. On the one hand, it can ensure that the heating area can more stably heat the atomized liquid, which is helpful to improve the atomization effect. On the other hand, it can also protect the heating body 2, which is helpful to prolong the service life of the heating body 2 and improve the use performance of the atomization assembly.

[0049] Through the first support section 21 and the second support section 22, not only the stability of the overall structure of the heating body 2 can be enhanced, but also the connection with the first electrode 3 and the second electrode 4 is facilitated. The structure design is reasonable, the structure space is effectively utilized, and the compactness of the structure of the atomization assembly is improved.

[0050] In the above embodiments, the heating section 23 is distributed along the extension direction of the atomization air passage 141. In order to ensure the stable connection with the first electrode 3 and the second electrode 4, further, the width size of the first support section 21 can be equal to or greater than the shaft diameter size of the part of the first electrode 3 extending into the atomization air passage 141, and the width size of the second support section 22 can be equal to or greater than the shaft diameter size of the part of the second electrode 4 extending into the atomization air passage 141. In this way, sufficient connection area can be provided for the first electrode 3 and the second electrode 4 to further enhance the connection strength between the first electrode 3 and the second electrode 4 and the heating body 2.

[0051] The connection mode of the first electrode 3 and the first support section 21 can be welding connection, clamping connection, or other fixed connection mode, as long as the stable connection between the first electrode 3 and the heating body 2 can be ensured, which is not limited here.

[0052] The connection mode of the second electrode 4 and the second support section 22 can be welding connection, clamping connection, or other fixed connection mode, as long as the stable connection between the second electrode 4 and the heating body 2 can be ensured, which is not limited here.

[0053] Continuing to refer to FIGS. 2-6, in some embodiments, the heating section 23 has two conductive portions 231 and a heating portion 232, the two conductive portions 231 are respectively formed at two ends of the heating section 23, one of the two conductive portions 231 is arranged adjacent to the first electrode 3, and the other is arranged adjacent to the second electrode 4, and the heating region is formed in the heating portion 232.

[0054] In this way, the circuit path between the heating portion 232 and the first electrode 3 and the second electrode 4 can be reduced, so that the path of the current reaching the heating portion 232 is shorter, thereby improving the heating power of the heating portion 232 and improving the thermal efficiency, thereby improving the atomization efficiency and effect of the atomization assembly.

[0055] The shape of the conductive portion 231 can be triangular, which can provide stable connection for the heating portion 232 and further improve the structural performance of the heating section 23, effectively preventing the heating section 23 from deforming, so that the heating body 2 can be normally used when the heating body 2 is in close contact with the oil guiding cotton and the like.

[0056] In other embodiments, the conductive portion 231 can also be connected to a sheet or the like, or the conductive portion 231 can also be arranged in other shapes, which are not limited herein.

[0057] In some embodiments, the heating portion 232 is provided with a plurality of support portions 233 on both sides, the plurality of support portions 233 are distributed along the airflow direction defined by the atomization air passage 141, and the plurality of support portions 233 are used to provide support force for the heating portion 232.

[0058] Through the plurality of support portions 233, on the one hand, the heating portion 232 is prevented from deforming when it is in close contact with the oil guiding cotton and the like, which helps to improve the atomization efficiency and effect of the heating portion 232 on the atomized liquid, and on the other hand, the structural stability of the heating body 2 can be further improved.

[0060] In this way, the atomization assembly can be conveniently assembled, and the air passage piece 14, the heating body 2 and the oil guide body 12 can be firmly mounted in the accommodating cavity 112, and the possibility of loosening of the air passage piece 14 can be effectively avoided.

[0061] The sealing seat 13 blocks the opening of the accommodating cavity 112, so that a closed cavity is formed in the accommodating cavity 112, the stability of airflow flowing in the atomization air passage 141 is ensured, and airflow turbulence is avoided. The oil guide body 12 can be an oil guide cotton, a liquid storage cotton, an oil guide rope or an integrated cotton.

[0062] Alternatively, the connection between the sealing seat 13 and the support 11 can be a clamping connection or a fixed connection through a screw, as long as the sealing seat 13 can be stably fixed on the support 11. The support assembly 1 can further include an oil absorbing cotton, which is arranged between the air passage piece 14 and the sealing seat 13. The oil absorbing cotton can absorb tobacco tar, thereby effectively reducing the phenomenon of oil leakage.

[0063] In the embodiment, the air passage piece 14 is a silica gel structure, and a long strip gap is formed in the side of the air passage piece 14 facing the oil guide body 12. The long strip gap is in communication with the atomization air passage 141, and the heating portion 232 of the heating body 2 is located at the long strip gap. The heated atomized smoke flows into the atomization air passage 141 through the long strip gap.

[0064] The first electrode 3 includes a first mounting portion 31 and a first connecting portion 32, and the sealing seat 13 is provided with a first mounting hole 132.

[0066] In the embodiments of the present application, the hole walls of the first mounting hole 132 and the second mounting hole 133 are each provided with a limiting plane, and the outer peripheral wall of the first mounting portion 31 and the second mounting portion 41 is formed with a stop plane, which is in plane contact with the limiting plane. In this way, the rotation of the first electrode 3 and the second electrode 4 can be prevented, so as to ensure the stability of the installation of the first electrode 3 and the second electrode 4 on the support assembly 1, and also avoid the rotation of the heating body 2 when the first electrode 3 and the second electrode 4 rotate, so as to prevent the heating body 2 from being twisted and deformed, which is very helpful for the transportation of the atomization assembly and ensures the safety during transportation.
