Description

Technical Field

[0002] An atomizer is a device that heats and atomizes an aerosol generating matrix into an aerosol, including an atomizing core for heating and atomizing the atomizing liquid.

[0003] In related technologies, when the atomizing core heats and atomizes the introduced atomizing liquid, in addition to generating aerosols, it also generates salt spray and / or small droplets. When the salt spray and / or small droplets are sprayed and / or diffused around, some of the salt spray and / or small droplets will directly impact the connection port of the air intake channel, causing the air intake channel to be blocked.

[0016] In some implementations, the virtual plane containing the first connection port is inclined relative to the first direction toward the atomizing core, and the angle between the virtual plane and the first direction is not greater than 60° and not less than 15°.

[0017] In some embodiments, the maximum distance between the first communication port and the atomizing core along the second direction is not greater than 3 mm and not less than 1 mm.

[0018] In some embodiments, the housing has an air-blocking channel located upstream of the air intake channel in the airflow direction, the cross-sectional area of ​​the air-blocking channel being smaller than the cross-sectional area of ​​the air intake channel; and / or,

[0020] The housing has an air outlet communicating with the air outlet channel. The air outlet is located on the side of the atomizing core away from the atomizing chamber along the second direction. The air inlet channel extends between the two opposite sides of the housing along the second direction. The housing also has a liquid storage tank communicating with the air inlet channel. The liquid storage tank and the first communication port are located at opposite ends of the air inlet channel along the extension direction.

[0021] In some embodiments, the air outlet channel has a second communication port communicating with the atomizing chamber, and the second communication port and the first communication port are respectively located on opposite sides of the atomizing core along the first direction.

Detailed Implementation

[0035] In the description of the embodiments in this application, it should be noted that the terms "first direction" and "second direction" are based on the appended... Figure 1 The orientation or positional relationship shown, "third direction" is based on the attached Figure 3 The orientation or positional relationship shown is merely for the convenience of describing the embodiments of this application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the embodiments of this application.

[0036] This application provides an aerosol generating device; please refer to [link / reference]. Figure 1 and Figure 3 The aerosol generating device includes an atomizer 10 and a power supply component 20, which is electrically connected to the atomizer 10.

[0037] The aerosol generating device is used to produce aerosols for users to inhale or for medical, cosmetic, and other applications. The power supply unit 20 works in conjunction with the nebulizer 10 to supply power to the nebulizer 10 and control its operating status. The power supply unit typically includes a battery 22 for supplying power to the nebulizer 10 and an electronic control board 21 for controlling the heating of the nebulizer 10. The nebulizer 10 is used to heat and atomize the aerosol liquid after being powered on to generate an aerosol.

[0038] Please see Figures 1 to 4 The atomizer 10 in this embodiment includes a housing 11 and an atomizing core 12.

[0039] The housing 11 has an atomizing chamber 11a and an air inlet channel 11b and an air outlet channel 11c respectively communicating with the atomizing chamber 11a. The air inlet channel 11b has a first connecting port 11b1 communicating with the atomizing chamber 11a, and the first connecting port 11b1 is located on one side of the atomizing chamber 11a along a first direction of the housing 11. The atomizing core 12 is in fluid communication with the atomizing chamber 11a, and the atomizing core 12 is located on one side of the atomizing chamber 11a along a second direction of the housing 11. The second direction intersects the first direction, and on a projection plane perpendicular to the second direction, the projection of the atomizing core 12 and the projection of the first connecting port 11b1 are offset.

[0040] The atomizing core 12 is used to heat and atomize the atomizing liquid. The atomizing core 12 is in fluid communication with the atomizing chamber 11a, that is, the atomizing surface of the atomizing core 12 faces the atomizing chamber 11a, so that the aerosol, salt spray, and small droplets generated by the heating and atomization of the atomizing liquid are released into the atomizing chamber 11a. Since the atomizing core 12 is located on one side of the atomizing chamber 11a along the second direction of the housing 11, the aerosol, salt spray, and small droplets generated by the atomization of the atomizing core 12 are released from one side of the atomizing chamber 11a along the second direction into the atomizing chamber 11a.

[0041] Please see Figure 1 When a user inhales from the atomizer 10, external airflow enters the atomization chamber 11a through the air inlet channel 11b and carries the aerosol generated by the atomizing core 12 to the air outlet channel 11c to reach the user's mouth. Thus, the external airflow can smoothly carry the aerosol out of the atomization chamber 11a.

[0042] In other words, the air intake channel 11b refers to the channel through which external airflow flows into the atomizing chamber 11a, and the air outlet channel 11c refers to the channel through which external airflow and aerosol flow from the atomizing chamber 11a to the user's mouth.

[0043] On the projection plane perpendicular to the second direction, the projection of the atomizing core 12 and the projection of the first connecting port 11b1 are offset. That is, in the second direction, the first connecting port 11b1 avoids the atomizing surface of the atomizing core 12. In the first direction, the projection of the first connecting port 11b1 and the projection of the atomizing core 12 do not coincide. This can prevent the salt mist and / or small droplets generated by the atomization of the atomizing core 12 from directly rushing towards the first connecting port 11b1 along the second direction, causing blockage of the air intake channel 11b.

[0044] For example, please refer to Figure 2 The minimum distance H1 between the first connecting port 11b1 and the atomizing core 12 along the first direction is not greater than 3mm and not less than 1mm. This not only reduces the possibility of salt spray and / or small droplets directly hitting the first connecting port 11b1 and causing blockage of the air intake channel 11b, but also allows the external airflow flowing into the atomizing chamber 11a from the first connecting port 11b1 to fully flow through the central atomizing area of ​​the atomizing core 12. While removing heat from the atomizing core 12, it also improves the mixing effect between the external airflow and the aerosol, thereby better carrying the aerosol out of the atomizing chamber 11a and preventing the generation of a burnt smell. More preferably, the minimum distance H1 between the first connecting port 11b1 and the atomizing core 12 along the first direction can be 1.5mm.

[0045] The cross-sectional shape of the first connecting port 11b1 is not limited. For example, the cross-sectional shape of the first connecting port 11b1 includes, but is not limited to, square, racetrack, circular or elliptical shapes, so that the airflow flowing out of the first connecting port 11b1 is more dispersed and the mixing effect of external airflow and aerosol is improved.

[0046] The cross-sectional area of ​​the first connecting port 11b1 is not limited; for example, the cross-sectional area of ​​the first connecting port 11b1 is not greater than 5 mm². 2 And not less than 1.5mm 2 This is to disperse the airflow exiting from the first connecting port 11b1, thereby improving the mixing effect between the external airflow and the aerosol. More preferably, the cross-sectional area of ​​the first connecting port 11b1 can be 3 mm². 2 .

[0047] In related technologies, the first connecting port is located directly below along the second direction, and the atomizing surface of the atomizing core is opposite to the first connecting port. As a result, the generated salt spray and / or small droplets directly impact the first connecting port of the air intake channel, causing the air intake channel to become blocked.

[0048] In this embodiment, the atomizing core 12 is located on one side of the atomizing chamber 11a along the second direction of the housing 11, and the first connecting port 11b1 is located on one side of the atomizing chamber 11a along the first direction of the housing 11. On the projection plane perpendicular to the second direction, the projection of the atomizing core 12 and the projection of the first connecting port 11b1 are misaligned. That is, the first connecting port 11b1 is not located directly below the atomizing core 12 along the second direction. When the atomizing core 12 heats and atomizes the atomizing liquid, the first connecting port 11b1 can avoid the salt mist and / or small droplets sprayed and dispersed along the second direction, thereby reducing the entry of salt mist and / or small droplets into the air intake channel 11b and effectively alleviating the blockage problem of the air intake channel 11b.

[0049] In some embodiments, please refer to Figure 1 The atomizing chamber 11a has a first side X1 and a second side X2 that are opposite each other along the second direction. The atomizing core 12 is located on the first side X1. The first connecting port 11b1 can be located inside the atomizing chamber 11a and faces the first side X1.

[0050] In other words, a portion of the air intake channel 11b extends into the atomizing chamber 11a, so that the first connecting port 11b1 is located between the first side X1 and the second side X2. This reduces the distance between the first connecting port 11b1 and the atomizing core 12 along the second direction, allowing the external airflow to carry the aerosol out of the atomizing chamber 11a more quickly.

[0051] For example, please refer to Figures 2 to 4 The housing 11 may include a protrusion 111 located in the atomizing chamber 11a and with one end facing the first side X1. At least a portion of the air intake channel 11b is located in the protrusion 111, and the first connecting port 11b1 is provided at the end of the protrusion 111 facing the first side X1.

[0052] In other words, the protrusion 111 is spaced apart from the inner wall of the atomizing chamber 11a on the first side X1 along the second direction, and the first connecting port 11b1 is located on the side of the protrusion 111 along the second direction close to the first side X1, so as to further reduce the salt spray and / or small droplets that are sprayed and dispersed from entering the air intake channel 11b.

[0053] Please see Figures 1 to 4 The housing 11 has an air outlet 11d communicating with the air outlet channel 11c. The air outlet 11d is located on the side of the atomizing core 12 away from the atomizing cavity 11a along the second direction. The protrusion 111 can extend from the second side X2 of the atomizing cavity 11a to the first side X1, and the protrusion 111 and the atomizing cavity 11a are spaced apart on the inner wall surface of the protrusion 111.

[0054] The air outlet 11d refers to the outlet from which aerosols flow from the air outlet channel 11c into the user's oral cavity.

[0055] The first side X1 of the atomizing chamber 11a refers to the side of the atomizing chamber 11a closest to the air outlet 11d along the second direction, and the second side refers to the side of the atomizing chamber 11a away from the air outlet 11d along the second direction. It is understood that the aerosol generated by the atomizing core 12 heating and atomizing the atomizing liquid generally has a high temperature. High-temperature aerosols are prone to condensation when cooled, and under the influence of gravity, the condensate tends to flow along the inner wall of the atomizing chamber 11a from the first side to the second side.

[0056] The protrusion 111 extends from the second side X2 of the atomizing chamber 11a towards the first side X1. That is, the protrusion 111 protrudes from the inner wall surface of the atomizing chamber 11a located on the second side X2, preventing condensate from accumulating on the second side X2 and flowing into the air intake channel 11b from the first connecting port 11b1. The protrusion 111 is spaced apart from the inner wall surface of the atomizing chamber 11a located around its periphery; that is, the outer wall surface of the protrusion 111 does not contact the inner wall surface of the atomizing chamber 11a, preventing condensate from flowing into the air intake channel 11b along the inner wall surface of the atomizing chamber 11a.

[0057] Please see Figure 1 and Figure 2 The atomizing chamber 11a has a first inner wall surface 11a1, a second inner wall surface 11a2 and a third inner wall surface 11a3. The first inner wall surface 11a1 is located on the first side X1 of the atomizing chamber 11a. The second inner wall surface 11a2 and the first connecting port 11b1 are located on the same side of the atomizing chamber 11a along the first direction. The first inner wall surface 11a1 and the second inner wall surface 11a2 can be transitioned by the chamfer or rounded corner of the third inner wall surface 11a3.

[0058] In other words, the third inner wall surface 11a3 is located between the first inner wall surface 11a1 and the second inner wall surface 11a2, and is in contact with both the first inner wall surface 11a1 and the second inner wall surface 11a2. The third inner wall surface 11a3 can be a slope or a concave arc surface. If the first inner wall surface 11a1 and the second inner wall surface 11a2 are directly in contact to form an angle, the condensate formed by the aerosol when it cools is likely to accumulate at the angle. When the gravity of the condensate is greater than the surface tension, the condensate drips onto the second side of the atomizing chamber 11a, and the condensate is likely to drip into the air intake channel 11b from the first connecting port 11b1. The transition between the first inner wall surface 11a1 and the second inner wall surface 11a2 through the chamfer or rounded corner of the third inner wall surface 11a3 can effectively prevent the condensate from accumulating on the first side of the atomizing chamber 11a, thereby further reducing the probability of the air intake channel 11b being blocked.

[0059] In other embodiments, the atomizing chamber 11a may also have only a first inner wall surface 11a1 and a second inner wall surface 11a2, with the first inner wall surface 11a1 and the second inner wall surface 11a2 in contact. The first inner wall surface 11a1 is inclined relative to the second inner wall surface 11a2 towards the atomizing core 12, or the first inner wall surface 11a1 is a concave arc surface.

[0060] For an embodiment where the protruding post 111 and the atomizing chamber 11a are spaced apart on the inner wall surface around the protruding post 111, please refer to [the original text]. Figure 2 The protruding post 111 and the second inner wall surface 11a2 form a liquid storage space 11a5 within the atomizing chamber 11a. On the projection plane perpendicular to the second direction, the projection of the third inner wall surface 11a3 coincides with at least a portion of the liquid storage space 11a5. That is, the liquid storage space 11a5 faces the second inner wall surface 11a2, thereby allowing the condensate to flow smoothly into the liquid storage space 11a5 along the second inner wall surface 11a2 and preventing the condensate from flowing directly into the first connecting port 11b1.

[0061] In some embodiments, please refer to Figures 1 to 4 The virtual plane where the first connecting port 11b1 is located can be tilted relative to the first direction towards the atomizing core 12. That is, the virtual plane where the first connecting port 11b1 is located has a certain angle with the first direction. The first connecting port 11b1 is set towards the atomizing core 12. Along the second direction from the side close to the atomizing core 12 to the side away from the atomizing core 12, the distance between the first connecting port 11b1 and the first inner wall surface 11a1 gradually decreases. When the external airflow enters the atomizing chamber 11a from the air intake channel 11b, the virtual plane where the first connecting port 11b1 is located can better guide the external airflow to the atomizing core 12 by tilting relative to the first direction towards the atomizing core 12, so that the external airflow can carry the aerosol out of the atomizing chamber 11a more quickly.

[0062] The angle between the virtual plane and the first direction is not limited in size; for example, please refer to [reference needed]. Figure 1 and Figure 2 The angle θ between the virtual plane and the first direction is not greater than 60° and not less than 15°, so that the first liquid outlet has a better guiding effect.

[0063] For example, please refer to Figure 1 and Figure 2 The maximum distance between the first connecting port 11b1 and the atomizing core 12 along the second direction is not greater than 3mm and not less than 1mm, preferably 2mm, so that the first connecting port 11b1 is closer to the atomizing core 12, and the external airflow can carry the aerosol to the air outlet channel 11c more quickly.

[0064] In some embodiments, please refer to Figure 1 and Figure 2The housing 11 may have an air-blocking channel 11e located upstream of the air intake channel 11b along the airflow direction, and the cross-sectional area of ​​the air-blocking channel 11e is smaller than the cross-sectional area of ​​the air intake channel 11b.

[0065] The air-blocking channel 11e is used to control the air intake resistance. In other words, by controlling the cross-sectional area of ​​the air-blocking channel 11e, the flow rate and velocity of the external airflow can be controlled, thereby enabling the atomized liquid to be fully atomized and improving the vaping experience.

[0066] In some embodiments, please refer to Figure 2 The air intake passage 11b may include at least two connecting sections 11b2. Among the two adjacent connecting sections 11b2, the cross-sectional area of ​​the connecting section 11b2 located upstream in the airflow direction is larger than the cross-sectional area of ​​the connecting section 11b2 located downstream in the airflow direction, so that an air-blocking hole 11b3 is formed at the junction of the two adjacent connecting sections 11b2.

[0067] The air choke 11b3 is used to control the intake resistance. The air choke 11b3 is located between two adjacent connecting sections 11b2, that is, the air choke 11b3 is located inside the intake channel 11b, thereby reducing the airflow velocity inside the intake channel 11b.

[0068] Figure 2 In the atomizer 10 shown, the air intake channel 11b includes three connecting sections 11b2. The cross-sectional area of ​​the three connecting sections 11b2 decreases sequentially along the airflow direction, thereby forming two air-blocking holes 11b3 to further reduce the airflow velocity inside the air intake channel 11b.

[0069] In some embodiments, please refer to Figure 1 and Figure 2 The housing 11 has an air outlet 11d that communicates with the air outlet channel 11c. The air outlet 11d is located on the side of the atomizing core 12 away from the atomizing chamber 11a along the second direction. The air inlet channel 11b can extend between the two opposite sides of the housing 11 along the second direction. The housing 11 also has a liquid storage tank 11f that communicates with the air inlet channel 11b. The liquid storage tank 11f and the first communication port 11b1 are located at opposite ends of the air inlet channel 11b along the extension direction.

[0070] The liquid storage tank 11f is used to contain the condensate in the air intake channel 11b. That is, the condensate in the air intake channel 11b flows along the side wall of the air intake channel 11b towards the side where the liquid storage tank 11f is located under the action of gravity.

[0071] For the air-blocking channel 11e located upstream of the airflow path of the intake channel 11b, the air-blocking channel 11e can extend in a first direction. That is, the extension direction of the intake channel 11b intersects the extension direction of the air-blocking channel 11e, preventing condensate in the intake channel 11b from directly flowing into the air-blocking channel 11e and causing blockage of the air-blocking channel 11e. More preferably, please refer to... Figure 2 The gas blocking channel 11e can be located on one side of the liquid storage tank 11f along the first direction, so that the condensate flows directly into the liquid storage tank 11f without causing the gas blocking channel 11e to be blocked.

[0072] In some embodiments, please refer to Figure 1 and Figure 2 The air outlet channel 11c has a second communication port 11c1 that communicates with the atomizing chamber 11a. The second communication port 11c1 and the first communication port 11b1 can be located on opposite sides of the atomizing core 12 along the first direction.

[0073] In other words, in the first direction, the airflow path in the atomizing chamber 11a can cross the atomizing surface of the atomizing core 12, and the airflow can flow through the central atomizing area of ​​the atomizing core 12, so that the aerosol can quickly flow out of the atomizing chamber 11a along the airflow path, preventing the aerosol from entering the air intake channel 11b from the first connecting port 11b1. Thus, it can both prevent the aerosol from blocking the air intake channel 11b and increase the aerosol output.

[0074] For example, please refer to Figure 1 and Figure 2 The second connecting port 11c1 and the atomizing core 12 can be located on the same side of the atomizing chamber 11a along the second direction. That is, the second connecting port 11c1 is located diagonally above the first connecting port 11b1. In other words, the second connecting port 11c1 is located diagonally opposite the first connecting port 11b1 within the atomizing chamber 11a. The airflow can pass through the central atomizing area of ​​the atomizing core 12 along the diagonal of the atomizing chamber 11a, making the airflow smooth and fast. External airflow can pass better through the atomizing area of ​​the atomizing core 12, and can quickly carry the atomized gas to the air outlet 11d. In addition, when the second connecting port 11c1 is located on the first side of the atomizing chamber 11a near the air outlet 11d, it can also prevent condensate in the atomizing chamber 11a from entering the air outlet channel 11c.

[0075] Please see Figure 1 The air outlet channel 11c includes a transition section 11c2 with a second communication port 11c1 and an extension section 11c3 communicating with the transition section 11c2. The cross-sectional area of ​​the transition section 11c2 gradually increases from the end of the transition section 11c2 away from the atomizing chamber 11a to the end near the atomizing chamber 11a.

[0076] The transition section 11c2 has a larger cross-sectional area at the end near the atomizing chamber 11a and a smaller cross-sectional area at the end away from the atomizing chamber 11a. This can alleviate the flow separation and eddies caused by the abrupt right-angle change, reduce the local resistance loss of the airflow, and at the same time allow the airflow to flow more smoothly from the atomizing chamber 11a into the outlet channel 11c, thereby reducing the formation of condensate.

[0077] Preferably, the sidewall of the transition section 11c2 is inclined towards the atomizing core 12 along the first direction to achieve better airflow.

[0078] Please see Figure 1 The air inlet channel 11b and the air outlet channel 11c can be located on opposite sides of the atomizing chamber 11a along the second direction, respectively, to improve the smoothness of airflow and reduce the formation of condensate.

[0079] In some embodiments, please refer to Figure 2 and Figure 4 The atomizing chamber 11a has a fourth inner wall surface 11a4 on the side opposite to the first connecting port 11b1 along the first direction. The fourth inner wall surface 11a4 can be inclined relative to the first direction toward the atomizing core 12 to form a guide surface that guides the airflow toward the second connecting port 11c1.

[0080] The guide surface can smooth the curvature change of the airflow along the fourth inner wall surface 11a4, reducing centrifugal force disturbance caused by sudden changes in direction. The guide surface can push the airflow towards the first connecting port 11b1, improving the flow efficiency of the airflow and reducing the formation of eddies and condensate.

[0081] In some embodiments, please refer to Figures 1 to 3 The atomizer 10 may also include a liquid suction member 13 disposed in the housing 11. The liquid suction member 13 is located on the side of the atomizing chamber 11a opposite to the atomizing core 12 along the second direction and is in fluid communication with the atomizing chamber 11a.

[0082] The liquid absorption element 13 is used to absorb the condensate formed when the stored aerosol is cooled.

[0083] When the atomizer 10 is powered on and the atomizing core 12 heats and atomizes to generate an aerosol, the condensate generated by the high-temperature aerosol cooling in the atomization chamber 11a can flow along the inner wall of the atomization chamber 11a to the liquid suction element 13, where it is absorbed and stored. Similarly, the condensate generated by the high-temperature aerosol cooling in the air outlet channel 11c can also flow from the air outlet channel 11c into the atomization chamber 11a, where it is absorbed and stored by the liquid suction element 13. Thus, the condensate in the atomization chamber 11a will not easily flow into the air inlet channel 11b, causing air inlet blockage, and the problem of condensate blockage in the air outlet channel 11c can also be alleviated.

[0084] For example, please refer to Figure 4The housing 11 has a mounting post 112 located in the atomizing chamber 11a. The liquid guiding component can work together with the mounting post 112 to form a capillary channel 11b6. The capillary channel 11b6 is in fluid communication with the atomizing core 12 and the liquid suction component 13, respectively.

[0085] Capillary channels 11b6 refer to channels that allow the atomizing liquid to flow spontaneously within the channel under the action of capillary effect.

[0086] During the heating and atomization process of the atomizing core 12, the condensate stored in the liquid suction member 13 can flow to the atomizing core 12 along the capillary channel 11b6 under the action of capillary effect, so as to be heated and atomized by the atomizing core 12. This can avoid the problem of condensate accumulation caused by the liquid suction member 13 being unable to absorb condensate due to saturation of the liquid suction volume. In addition, the atomized liquid in the liquid storage chamber can also flow to the liquid suction member 13 through the atomizing core 12 along the capillary channel 11b6 and be stored in the liquid suction member 13. During the heating and atomization process of the atomizing core 12, the atomized liquid flows back to the atomizing core 12 along the capillary channel 11b6, thereby improving the utilization rate of the atomized liquid.

[0087] In some embodiments, please refer to Figure 4 The housing 11 has a liquid storage chamber 11g that is in fluid communication with the atomizing core 12, and the liquid storage chamber 11g is located on the side of the atomizing core 12 near the air outlet 11d.

[0088] The 11g storage chamber is used to store the atomizing liquid.

[0089] The fluid communication between the liquid storage chamber 11g and the atomizing core 12 means that the atomizing liquid in the liquid storage chamber 11g can flow to the atomizing core 12, so that the atomizing core 12 can heat and atomize the atomizing liquid. Since the liquid storage chamber 11g is located on the side of the atomizing core 12 closer to the air outlet 11d, the atomizing liquid in the liquid storage chamber 11g can flow to the atomizing core 12 under the action of gravity, thereby ensuring the atomization effect of the atomizing core 12 on the atomizing liquid.

[0090] Please see Figure 3 The housing 11 includes a support 113 and an oil tank 114. The support 113 has an atomizing chamber 11a and an air inlet channel 11b, with the opening of the atomizing chamber 11a facing the oil tank 114. The oil tank 114 has an air outlet channel 11c and a liquid storage chamber 11g. The atomizing core 12 is disposed at the liquid outlet of the liquid storage chamber 11g, with the atomizing surface of the atomizing core 12 facing the opening of the atomizing chamber 11a, so as to be in fluid communication with the atomizing chamber 11a. The support 113 and the oil tank 114 are detachably connected, thereby facilitating the assembly and maintenance of the atomizer 10.

[0091] In some embodiments, please refer to Figure 3 and Figure 4The atomizer 10 includes two electrodes 14 electrically connected to the atomizing core 12. The two electrodes 14 pass through the atomizing chamber 11a and are spaced apart along a third direction, wherein the third direction intersects with the first direction and the second direction respectively.

[0092] In other words, the atomizing core 12 is electrically connected to the power supply assembly 20 through two electrodes 14.

[0093] Please see Figure 1 and Figure 3 The power supply assembly 20 includes an electronic control board 21 and a battery 22 electrically connected to the electronic control board 21. The housing 11 has a mounting cavity (not shown in the figure), the electronic control board 21 is located in the mounting cavity, and part of the structure of the electrode 14 extends into the mounting cavity and is electrically connected to the electronic control board 21, thereby enabling the power supply assembly 20 to supply power to the atomizing core 12.
