For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0028] See also Figures 1 to 4The present application provides an atomizer assembly 100, comprising an atomizer bracket 10, an atomizer core and a base 20. The atomizer bracket 10 has an atomizer chamber 11, and the bottom of the atomizer bracket 10 is provided with an installation opening connected to the atomizer chamber 11, and the atomizer core is arranged on the atomizer bracket 10 and is connected to the atomizer chamber 11. The base 20 includes a base 21 and a guide column 22, the base 21 covers the installation opening, and the base 21 is provided with a swirl forming structure for introducing external gas into the atomizer assembly 100 and forming a spiral airflow, and the guide column 22 is arranged on the side of the base 21 facing the atomizer chamber 11, and the guide column 22 is used to guide the airflow to flow around the periphery of the guide column 22 and flow to the atomizer chamber 11. By providing a swirl forming structure, a spiral airflow can be formed in the atomizer assembly 100, and the guide column 22 arranged in the atomizer chamber 11 can be used to guide the spiral airflow entering from the base 21 to continue to rotate around the guide column 22, thereby further improving the degree of aggregation of the spiral airflow. On the one hand, the surface of the guide column 22 can be set to a smooth surface, that is, there is no need to set an additional spiral structure (such as a thread groove or a thread protrusion, etc.) on the surface of the guide column 22 or the inner wall surface of the atomizer bracket 10, but the guide column 22 is set in the atomizer chamber 11 to achieve the effect of guiding the airflow to flow in a spiral form, thereby simplifying the arrangement of the atomizer chamber 11 and the base 20, and reducing the space occupied by the guide column 22 in the atomizer chamber 11 without increasing the volume of the atomizer assembly 100, ensuring that the atomizer chamber 11 has enough space, thereby avoiding the problem of the atomizer chamber 11 space becoming narrower and causing the smoke to easily form condensate and cause blockage, thereby improving the reliability of the use of the atomizer assembly 100. On the other hand, the guide column 22 can guide the airflow to flow in the atomizer chamber 11 at a suitable speed, so that the airflow entering from the outside and the heated and atomized aerosol can be fully and evenly mixed, thereby improving the taste of the smoke.

[0029] Optionally, the guide post 22 is integrally formed with the base 21. This can simplify the design and manufacturing process of the base 20, thereby omitting the installation steps of the guide post 22 and the base 21, and improving the assembly efficiency and accuracy of the electronic atomization assembly 100.

[0030] In some embodiments, the swirl formation structure includes at least two air inlets 211 arranged on the base 21 and arranged circumferentially offset relative to the guide column 22, so that when the external gas enters from the air inlet 211, a spiral airflow surrounding the guide column 22 is formed. In this way, when the airflow enters along the air inlet 211, due to the misalignment of the flow direction of the airflow with the guide column 22, the two sides of the airflow will be subjected to asymmetric resistance and driving force after the airflow enters, so that the airflow produces a rotational motion around the guide column 22, and rises from the bottom to the top along the axial direction of the guide column 22, forming a spiral airflow, and then under the guidance of the guide column 22, it further flows along the periphery of the guide column 22 to improve the degree of aggregation, so that the flow speed and circulation effect of the smoke can be increased first, because after the smoke spirally rises along the rotating path, a larger airflow ring will be formed, so that the amount and concentration of the smoke are increased, so that the user can get more smoke experience. Secondly, it can also make the smoke enter the mouth more softly and evenly, avoid the airflow rushing straight, thereby reducing the stimulation of the smoke to the throat and improving the user experience. Furthermore, the spiral rising airflow design can effectively prevent the incompletely atomized atomized medium from flowing back or leaking out of the atomizing chamber 11, making it difficult for the atomized medium to flow back into the mouth or leak out to the air inlet, thereby avoiding the waste of smoke liquid and uncomfortable user experience. Finally, the spiral rising airflow can also increase the mixing degree of smoke and air, so that the temperature of the smoke can be better dissipated, thereby effectively reducing the combustion temperature of the smoke and reducing the irritation to the mouth and throat.

[0031] In some embodiments, the base 21 is provided with a swirl chamber 212, the swirl chamber 212 is connected to the atomizing chamber 11, the air inlet 211 is connected to the atomizing chamber 11 through the swirl chamber 212, and the guide column 22 is arranged in the swirl chamber 212. By using the swirl chamber 212, a space can be provided outside the atomizing chamber 11, and the airflow entering through the air inlet 211 can first form a swirl in the swirl chamber 212 and have a certain speed, and then continue to further gather under the guidance of the guide column 22 to form a spiral airflow with a higher speed. In this way, without increasing the volume of the atomizing bracket 10, the space formed by a part of the base 21 can be used to expand the space of the atomizing chamber 11, thereby improving the mixing effect of the airflow and the aerosol, thereby improving the atomization effect and the taste of the smoke.

[0032] In some embodiments, a groove is provided on the surface of the base 21 facing the atomizing chamber 11, and the groove is arranged around the outer periphery of the guide column 22 to form a cyclone chamber 212, and the air inlet 211 is arranged on the side wall or bottom wall of the groove. By providing the groove on the surface of the base 21, the space of the base 21 is saved.

[0033] In some examples, the air inlet 211 is arranged on the side wall of the groove, and the swirl forming structure also includes at least two air inlet channels 213 arranged on the base 21 and staggered relative to the circumference of the guide column 22, the air inlet channel 212 runs through the side wall of the groove, and the air inlet channel 213 is connected to one end of the swirl chamber 212 to form the air inlet 211, and the inner wall surface of the air inlet channel 213 is tangent to the inner wall surface of the groove. By using the design that the air inlet channel 213 is tangent to the inner wall of the groove, when the airflow enters the swirl chamber 212 along the air inlet channel 213, since the flow direction of the airflow has a certain angle with the radial direction of the swirl chamber 212, after entering the swirl chamber 212, the airflow will be subjected to asymmetric resistance and driving force on both sides of the airflow in the swirl chamber 212, so that the airflow generates a rotational motion around the guide column 22. Furthermore, along the axial direction of the guide column 22, the air inlet 211 is flush with the bottom surface of the groove, so that the space in the height direction of the swirl chamber 212 (i.e., the axial direction of the guide column 22) can be fully utilized, so that the airflow can pass through a sufficiently long path during the spiral ascent to increase the speed and concentration of the airflow to the desired level.

[0034] In other examples, the air inlet 211 is arranged on the bottom wall of the groove, the air inlet channel 213 penetrates the bottom wall of the groove, the air inlet channel 213 is connected to one end of the swirl chamber 212 to form the air inlet 211, and the air inlet channel 213 is axially inclined or spirally shaped relative to the guide column 22. In this way, the angle between the air inlet channel 213 and the axial direction of the guide column 22 can be utilized so that the gas has an initial velocity and direction of spiral flow when entering the swirl chamber 212, so as to further form a spiral airflow under the guidance of the guide column 22.

[0035] Of course, in other examples, the design of the air inlet channel 213 may not be adopted, but the airflow may be introduced through the base 20 with a spiral groove structure, so that the airflow has a certain initial velocity and angle of spiral motion after entering the swirl chamber 212.

[0036] In some embodiments, the guide post 22 is spaced apart from the air inlet 211. By spacing the air inlet 211 and the guide post 22 apart, after the airflow enters the atomizing chamber 11 through the air inlet 211, there is enough space to form a swirl. Compared with the solution of setting a threaded groove on the surface of the guide post 22 and making the outer wall of the guide post 22 fit the inner wall of the swirl chamber 212, the present application sets the air inlet 211 and the guide post 22 apart, and sets the guide post 22 and the inner wall surface of the atomizing chamber 11 apart, which can provide a larger space for the airflow to form a spiral state, ensuring sufficient air intake and air intake stability.

[0037] In some embodiments, along the radial direction of the base 21, the inner wall of the groove is flush with the inner wall of the atomizing chamber 11. In this way, the airflow can flow smoothly in the process of entering the atomizing chamber 11 from the cyclone chamber 212, avoiding the step formed by the inconsistent inner diameter of the cyclone chamber 212 and the atomizing chamber 11 to disturb the airflow and cause the airflow velocity or the degree of aggregation to decrease. It is understandable that the cross-sectional shape and size of the inner wall surface of the cyclone chamber 212 are adapted to the cross-sectional shape and size of the inner wall of the atomizing chamber 11. For example, if the cross-sectional shape of the inner wall surface of the atomizing chamber 11 is circular or elliptical, the cyclone chamber 212 is also correspondingly set to a circular or elliptical shape. In addition, this can also ensure the sealing performance between the base 21 and the atomizing bracket 10, and avoid leakage of the airflow from the connection position between the two.

[0038] It should be emphasized that, compared with the atomizing chamber 11 with a square or other polygonal cross-section, the atomizing chamber 11 with a circular or elliptical cross-section has a better convergence effect on the airflow, so that the airflow can reach the required speed faster to meet the atomization requirements of the atomizing assembly 100.

[0039] In some embodiments, one end of the guide column 22 is connected to the base 21, and the other end extends into the atomizing chamber 11. In this way, the guiding and converging effect of the guide column 22 on the spiral airflow can continue from the air inlet 211 to the atomizing chamber 11, so as to achieve a good airflow acceleration effect.

[0040] In some embodiments, along the axial direction of the atomizing chamber 11, the atomizing chamber 11 includes an air intake section and an atomizing section, the inner diameter of the air intake section is smaller than the inner diameter of the atomizing section, the air intake section is connected to the cyclone chamber 212, and at least part of the guide column 22 extends into the atomizing section. By using the air intake section with a smaller inner diameter, the speed of the spiral airflow can be quickly increased, and then, after entering the atomizing section, the inner diameter of the atomizing section increases, so that the airflow diffuses and the airflow speed is reduced, so that the airflow and the aerosol can be fully mixed to form smoke.

[0041] In some embodiments, the height of the guide post 22 is 6.5mm to 12mm, for example, it can be 6.5mm, 7.0mm, 8.0mm, 10.0mm, 11.0mm, 12.0mm, etc. By setting the height of the guide post 22 within the above range, it can be ensured that the guide post 22 can play a good guiding role on the airflow to form a spiral airflow of sufficient speed, and at the same time, it can also avoid the problem that the guide post 22 is set too high, causing the atomization chamber 11 to narrow and making the smoke easily form condensate. In other words, when the height of the guide post 22 is set lower than 6.5mm, the guide post 22 is difficult to play a good guiding role on the airflow, and the acceleration and spiral flow effects of the airflow are not good, and it is difficult to achieve the goal of increasing the airflow speed and improving the mixing effect. When the height of the guide post 22 is set higher than 12mm, there will be a blocking effect on the airflow, resulting in an excessively fast airflow speed and difficulty in fully mixing with the aerosol, and there will be a problem that the smoke is easy to form condensate when it hits the guide post 22.

[0042] In some embodiments, see Figure 5 The side wall of the atomizing bracket 10 is also provided with a hollow portion 13, which is connected to the atomizing chamber 11, and is not connected to the installation opening. The atomizing core includes a heating element 30 and an oil guide body 40, the heating element 30 is arranged in the hollow portion 13, and the oil guide body 40 is arranged on the side of the heating element 30 away from the atomizing chamber 11. The oil guide body 40 can conduct the adsorbed atomizing medium to the heating element 30, and the heating element 30 can heat the atomizing medium to form an aerosol after being electrically heated. The aerosol can enter the atomizing chamber 11 through the hollow portion 13, and then mix with the spiral airflow to form smoke for the user to inhale. The hollow portion 13 is not connected to the mounting opening, which means that after the spiral airflow enters the mounting opening of the atomizer bracket 10, it flows at least a certain distance before reaching the bottom of the hollow portion 13. In this way, the airflow has enough space to be accelerated and gathered, so that when mixing with the aerosol, the airflow can reach a sufficient speed, so that it can be fully mixed with the aerosol to form smoke and leave the atomizer chamber 11 at a sufficient speed.

[0043] In some embodiments, along the axial direction of the guide column 22, the top of the guide column 22 does not exceed 1 / 4 of the height of the hollow portion 13. In this way, the risk of smoke hitting the outer surface of the guide column 22 to form condensate can be reduced. This is because when the top of the guide column 22 exceeds 1 / 4 of the height of the hollow portion 13, that is, a larger portion of the guide column 22 extends into the position of the corresponding heating element 30 of the atomization chamber 11, at this time, the aerosol formed by atomization of the heating element 30 has a higher temperature, and the aerosol is easy to form condensate on the surface of the guide column 22 when it contacts the guide column 22. Therefore, by controlling the height of the guide column 22, the performance and reliability of the atomization assembly 100 can be improved.

[0044] In the second aspect, the present application further provides an electronic atomization device (not shown), which includes the atomization assembly 100 provided in the first aspect. Of course, the electronic atomization device may also include a housing, a nozzle and other structures.
