Description

[0002] Electronic cigarettes are powered by batteries, which use heating wires to heat the oil into atomized form, and then draw the atomized oil out through a mouthpiece to achieve an effect similar to smoking.

[0003] The atomizer is the core component of the electronic cigarette. The current atomizer atomizes the e-liquid during the heating process of the ceramic heating wire, and the airflow entering through the air inlet brings the atomized e-liquid to the air outlet for the user to inhale. However, as traditional atomizers become thinner and thinner, the space of the airflow channel is compressed, resulting in a larger airflow resistance in the atomizer; when the user inhales, a fast airflow is generated, and the atomized e-liquid in the fast airflow is easy to condense after collision, which increases the content of condensed e-liquid in the mixed airflow and affects the taste of the electronic cigarette.

[0077] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0078] Reference Figures 1 to 10 The embodiment of the present application provides an atomization device, which is used for atomizing the e-liquid in an electronic cigarette, and the atomization device comprises:

[0079] A housing 1, wherein an air outlet channel 11, an air inlet hole 151, an oil storage chamber 12 and an atomization chamber 13 are provided in the housing 1, wherein the oil storage chamber 12 and the atomization chamber 13 are arranged along a first direction, the oil storage chamber 12 is used to store a medium to be atomized, and the air inlet hole is communicated with the atomization chamber;

[0080] An atomizer assembly 2, the atomizer assembly 2 is disposed in the housing 1 and located between the oil storage chamber 12 and the atomizer chamber 13, and the atomizer assembly 2 includes an airway structure 21 and an atomizer core 24;

[0081] The airway structure 21 is provided with a communication channel connecting the atomizing chamber and the air outlet channel 11, and the communication channel is at least partially inclined relative to the first direction. The atomizing core is used to atomize the medium to be atomized and release the aerosol toward the atomizing chamber;

[0082] In a second direction, the atomizer core 24 is disposed between the airway structure 21 and the housing 1 , and the second direction is orthogonal to the first direction.

[0083] Specifically, the size of the shell 1 in the length direction is greater than the size of the shell 1 in the width direction, and the size of the shell 1 in the width direction is greater than the size of the shell 1 in the thickness direction. The length direction, the width direction, and the thickness direction may be the X direction, the Y direction, and the Z direction in the figure, respectively. The first direction may be the length direction of the shell 1, and the second direction may be the width direction of the shell 1.

[0084] In one embodiment, the air outlet channel 11 may be disposed in the shell 1 along the length direction of the shell 1 to form an air outlet path of the shell 1 in the length direction.

[0085] Specifically, at least part of the connecting channel is inclined relative to the first direction. The connecting channel may be completely inclined relative to the first direction, or part of the connecting channel may be inclined relative to the first direction, while the remaining part of the connecting channel extends along the first direction.

[0086] The airflow entering from the air inlet 151 can be fully mixed with the smoke atomized by the atomizer core 24 in the atomizer chamber 13, and the atomized smoke can be effectively carried to the air outlet channel 11 through the airway structure 21; and when the connecting channel is at least partially inclined relative to the first direction, and the atomizer core 24 is arranged between the oil storage chamber 12 and the atomizer chamber 13, the atomizer core 24 and the airway structure 21 can form a large-space atomizer chamber, and at the same time, the inclined connecting channel can extend the stroke of the airflow inside the atomizer device and reduce the suction resistance of the airflow inside the atomizer device when it flows; the user can generate a smooth airflow when inhaling, avoiding the condensation of the atomized smoke in the fast airflow after the collision, reducing the content of condensed smoke oil in the mixed airflow, and ensuring the smoking taste of the electronic cigarette equipped with the atomizer device.

[0087] The atomizer device provided in the embodiment of the present application includes a shell 1, in which an air outlet channel 11, an air inlet hole 151, an oil storage chamber and an atomizer chamber are provided; an atomizer assembly 2, which is arranged in the shell 1, and the atomizer assembly 2 includes an airway structure 21 and an atomizer core 24; the connecting channel is at least partially inclined relative to the first direction; in the second direction, the atomizer core 24 is arranged between the oil storage chamber 12 and the atomizer chamber 13, and the atomizer core 24 and the airway structure 21 can form a large-space atomizer chamber, and at the same time, the inclined connecting channel can extend the stroke of the airflow inside the atomizer device, reduce the suction resistance of the airflow inside the atomizer device when flowing, and ensure the smoking taste of the electronic cigarette equipped with the atomizer device.

[0088] Alternatively, see Figures 1 to 6 , the communication passage includes a straight airway section 212 and an oblique airway section 213 connected to each other;

[0089] The straight air passage section 212 is in communication with the air outlet channel 11 , and the oblique air passage section 213 is in communication with the atomization chamber 13 .

[0090] Specifically, in the length direction of the shell 1, the straight airway section 212 extends in a straight line and has a vertical airflow channel inside. At the same time, the air outlet channel 11 can be arranged in the shell 1 along the length direction of the shell 1, that is, the straight airway section 212 and the air outlet channel 11 extend in the same direction, which can facilitate the connection and conduction of the straight airway section 212 and the air outlet channel 11.

[0091] The oblique airway section 213 is obliquely arranged in the shell 1 and connects the straight airway section 212 and the atomization chamber 13. At the same time, there is an oblique airflow channel inside the oblique airway section 213, which can extend the stroke of the airflow inside the atomization device and reduce the suction resistance of the airflow inside the atomization device when flowing.

[0092] Optionally, in the width direction of the housing 1 , a distance between an end of the communication channel away from the airway structure 21 and the atomizer core 24 is smaller than a distance between the airway structure 21 and the atomizer core 24 .

[0093] Specifically, the atomizer core 24 and the airway structure 21 can be arranged along Figure 1 For example, the atomizer core 24 is offset to one side of the shell 1, and the airway structure 21 is offset to the other side of the shell 1. The atomizer core 24 and the airway structure 21 can form a large atomization chamber on the atomization side of the atomizer core 24.

[0094] The distance between the end of the connecting passage away from the airway structure 21 and the atomizer core 24 is smaller than the distance between the airway structure 21 and the atomizer core 24, that is, in the flow direction of the airflow, the oblique airway section 213 forms an airway structure obliquely extending from the side of the shell 1 to the center of the shell 1, which can make the intake airflow and the atomized smoke in the atomization chamber fully mixed, while extending the stroke of the airflow inside the atomizer, thereby ensuring the stability of the airflow in the atomizer.

[0095] Optionally, an inclined angle is formed between the inclined air channel section 213 and the first direction of the shell 1, and the range of the inclined angle is 30°-80°.

[0096] Specifically, the angle between the oblique airway section 213 and the first direction of the housing 1 can be 35°, 45°, 60° or 70°, and the oblique airway section 213 has a lateral projection on the atomizer assembly 2, that is, the oblique airway section 213 not only provides airflow in Figure 1 The vertical flow path in the Figure 1 The flow path in the middle and transverse direction prolongs the travel of the air flow inside the atomizing device.

[0097] Specifically, the cross-sections of the straight airway segment 212 and the oblique airway segment 213 may be in the shape of a circular ring, a square ring, a rectangular ring, or other polygonal ring structures to match the suction resistance of the airflow during its flow.

[0098] Alternatively, see Figure 1 , Figures 17 to 19 The air outlet channel 11 is plugged into and matched with the connecting channel.

[0099] Specifically, the air outlet channel 11 can be integrally formed in the shell to simplify the assembly process of the atomizer device; and when assembling the atomizer assembly 2, the connecting channel provided on the airway structure 21 can be plugged into the air outlet channel 11, which facilitates the assembly between the connecting channel and the air outlet channel 11 while ensuring that the connecting channel and the air outlet channel 11 are connected.

[0100] Alternatively, see Figures 17 to 19 The atomizing assembly 2 includes an airway structural seal 25,

[0101] The airway structural seal 25 is at least partially sandwiched between the air outlet channel 11 and the communication channel.

[0102] Specifically, the airway structural seal 25 includes an annular groove 251 and an annular rib 252. The airway structural seal 25 is sleeved on the connecting channel through the annular groove 251. The air outlet channel 11 can be inserted into the connecting channel and clamped between the air outlet channel 11 and the connecting channel through the annular rib 252, so as to seal the gap between the air outlet channel 11 and the connecting channel through the airway structural seal 25 to ensure the sealing of the airflow channel.

[0103] Alternatively, see Figures 1 to 6 The atomizing assembly 2 includes a ventilation channel 22. When the pressure difference between the atomizing chamber and the oil storage chamber reaches a set threshold, the atomizing chamber and the oil storage chamber are connected through the ventilation channel.

[0104] Specifically, under normal conditions, that is, when the pressure difference between the atomization chamber 13 and the oil storage chamber 12 is less than a set threshold, since the atomization chamber 13 is connected to the outside through the air inlet, that is, the pressure in the atomization chamber 13 is close to or equal to the atmospheric pressure, the air pressure in the oil storage chamber 12 is maintained in a state where liquid can flow smoothly, so that the atomization assembly 2 can smoothly conduct the liquid in the oil storage chamber 12. At this time, the ventilation channel 22 is in a closed state. Specifically, the ventilation channel 22 can be closed by means of the surface tension of the ventilation channel 22, or the ventilation channel 22 can be blocked by a sealing member, and at the same time, the liquid in the oil storage chamber 12 can be prevented from entering the atomization chamber 13.

[0105] When the pressure difference between the atomization chamber 13 and the oil storage chamber 12 is greater than or equal to the set pressure, due to the large pressure difference between the atomization chamber 13 and the oil storage chamber 12, the surface tension in the ventilation channel 22 or the blockage of the ventilation channel 22 by the sealing member can be broken through the pressure difference greater than or equal to the set threshold. At this time, the ventilation channel 22 will be opened, allowing the air in the atomization chamber 13 to flow into the oil storage chamber 12, thereby ensuring the air pressure balance between the atomization chamber 13 and the oil storage chamber 12.

[0106] Optionally, the ventilation channel is formed between the airway structure and the atomizer core.

[0107] Specifically, since the atomizer core 24 is arranged between the airway structure 21 and the shell 1, the accommodating cavity in the shell 1 is divided into the oil storage cavity 12 and the atomization cavity 13; in order to facilitate the air pressure balance between the atomization cavity 13 and the oil storage cavity 12, the ventilation channel can be set between the airway structure and the atomizer core, while ensuring smooth ventilation between the oil storage cavity 12 and the atomization cavity 13, the structural integrity of the atomizer core 24 and the airway structure 21 is maintained.

[0108] Optionally, the airway structure 21 is provided with a ventilation groove 211 , and at least a portion of the ventilation channel 22 is formed in the ventilation groove 211 .

[0109] Specifically, when the airway structure 21 is arranged between the air outlet channel 11 and the shell 1, a ventilation groove 211 may be provided on the side of the second connecting end of the airway structure 21 facing the air outlet channel 11 to form at least a partial ventilation channel 22 between the airway structure 21 and the air outlet channel 11; or a ventilation groove 211 is provided on the side of the second connecting end of the airway structure 21 facing the shell 1 to form at least a partial ventilation channel 22 between the airway structure 21 and the shell 1 to ensure the gas phase balance between the atomization chamber 13 and the oil storage chamber 12.

[0110] Alternatively, see Figure 1 , Figures 11 to 16 The atomizer assembly 2 includes a seal 23 , and the seal 23 is sleeved on the airway structure 21 and the atomizer core 24 and abuts against the inner wall of the housing 1 .

[0111] Specifically, the sealing member 23 has a first assembly cavity 234 and a second assembly cavity 235, the second connection end of the airway structure 21 is assembled in the first assembly cavity 234, and the atomizer core 24 is assembled in the second assembly cavity 235. The second connection end of the airway structure 21 and the atomizer core 24 share a sealing member 23, and the sealing member 23 can seal the gap between the inner wall of the housing 1 and the airway structure 21 and the atomizer core 24, thereby preventing the smoke oil in the oil storage cavity 12 from leaking into the atomizer cavity 13.

[0112] In one embodiment, see Fig.11 and Fig.12 One or more annular sealing ribs 232 are arranged on the outer periphery of the sealing member 23. The sealing member 23 can seal the assembly gap between the housing 1 and the atomizing core 24 through the sealing ribs 232. The atomizing core 24 has a liquid suction surface 241 facing the oil storage cavity 12 and an atomizing surface 242 facing the atomizing cavity 13. Both the liquid suction surface and the atomizing surface are exposed from the sealing member 23.

[0113] Further, see Fig.11 , the sealing member 23 is provided with an elastic portion 231 , and the ventilation channel 22 has a channel port close to the oil storage chamber 12 ;

[0114] When the pressure difference between the atomizing chamber 13 and the oil storage chamber 12 is less than a set threshold, the elastic portion 231 covers the channel port;

[0115] When the pressure difference between the atomizing chamber 13 and the oil storage chamber 12 is greater than or equal to a set threshold, the elastic portion 231 is separated from the channel port under the action of the pressure difference.

[0116] Specifically, when the pressure difference between the pressure in the atomization chamber 13 and the pressure in the oil storage chamber 12 is less than a set threshold, the elastic portion 231 is covered on the channel port, and the elastic portion 231 can be used to cut off the connection between the ventilation channel 22 and the oil storage chamber 12. At this time, the ventilation channel 22 is in a closed state, which can prevent the liquid in the oil storage chamber 12 from entering the atomization chamber 13.

[0117] When the pressure difference between the pressure in the atomization chamber 13 and the pressure in the oil storage chamber 12 is greater than or equal to a set threshold, the elastic portion 231 is deformed under the action of the pressure difference, and the elastic portion 231 is separated from the channel port, that is, the elastic portion 231 can be opened by a pressure difference greater than or equal to the set threshold to block the ventilation channel 22, thereby maintaining the connection between the ventilation channel 22 and the oil storage chamber 12, allowing the air in the atomization chamber 13 to flow into the oil storage chamber 12, thereby ensuring the air pressure balance between the atomization chamber 13 and the oil storage chamber 12.

[0118] Optionally, a first ventilation groove is provided on the airway structure 21, and the sealing member 23 and the first ventilation groove are enclosed to form a first ventilation channel.

[0119] Specifically, since the seal 23 is sleeved on the airway structure 21 and can separate the oil storage chamber 12 and the atomization chamber 13 in the shell 1, in order to facilitate the connection between the ventilation channel 22 and the oil storage chamber 12 when the pressure difference between the pressure in the atomization chamber 13 and the oil storage chamber 12 is greater than or equal to a set threshold, so that the air in the atomization chamber 13 flows into the oil storage chamber 12, a first ventilation groove can be set on the airway structure 21, and the seal 23 and the first ventilation groove are enclosed to form a first ventilation channel. The air in the atomization chamber 13 can flow into the oil storage chamber 12 through the first ventilation channel, thereby ensuring the air pressure balance between the oil storage chamber 12 and the atomization chamber 13.

[0120] Optionally, a second ventilation groove is provided on the atomizer core 24, and the sealing member 23 and the second ventilation groove are enclosed to form a second ventilation channel.

[0121] Specifically, since the sealing member 23 is sleeved on the atomizing core 24 and can separate the oil storage chamber 12 and the atomizing chamber 13 in the shell 1, in order to facilitate maintaining the connection between the ventilation channel 22 and the oil storage chamber 12 when the pressure difference between the pressure in the atomizing chamber 13 and the oil storage chamber 12 is greater than or equal to a set threshold, so that the air in the atomizing chamber 13 flows into the oil storage chamber 12, a second ventilation groove can be provided on the atomizing core 24, and the sealing member 23 and the second ventilation groove are enclosed to form a second ventilation channel, and the air in the atomizing chamber 13 can flow into the oil storage chamber 12 through the second ventilation channel, thereby ensuring the air pressure balance between the oil storage chamber 12 and the atomizing chamber 13.

[0122] Optionally, a third ventilation groove is provided on the inner wall of the housing 1 , and the sealing member 23 and the third ventilation groove are enclosed to form a third ventilation channel.

[0123] Specifically, since the seal 23 is sleeved on the airway structure 21 and the atomizer core 24 and abuts against the inner wall of the shell 1 to separate the internal space of the shell 1 into the oil storage chamber 12 and the atomization chamber 13, in order to facilitate the connection between the ventilation channel 22 and the oil storage chamber 12 when the pressure difference between the pressure in the atomization chamber 13 and the oil storage chamber 12 is greater than or equal to a set threshold, so that the air in the atomization chamber 13 flows into the oil storage chamber 12, a third ventilation groove can be provided on the inner wall of the shell 1, and the seal 23 and the third ventilation groove are enclosed to form a third ventilation channel, and the air in the atomization chamber 13 can flow into the oil storage chamber 12 through the third ventilation channel, thereby ensuring the air pressure balance between the oil storage chamber 12 and the atomization chamber 13.

[0124] Furthermore, the above-mentioned first ventilation channel, second ventilation channel and third ventilation channel are respectively ventilation channels arranged on the atomization device in different embodiments of the present application. In other embodiments, it may only include one of the first ventilation channel, the second ventilation channel and the third ventilation channel, or it may include any two or three of the first ventilation channel, the second ventilation channel and the third ventilation channel.

[0125] Alternatively, see Fig.15 and Fig.16 The sealing member 23 includes a sealing baffle 233 , and the sealing baffle 233 is sandwiched between the airway structure 21 and the atomization core 24 .

[0126] Specifically, since the airway structure 21 and the atomizer core 24 are both hard structures, and the sealing member 23 is a soft structure, when the sealing partition 233 is sandwiched between the airway structure 21 and the atomizer core 24, the airway structure 21 and the atomizer core 24 can be separated by the sealing partition 233 while forming an interference fit with the airway structure 21 and the atomizer core 24, thereby preventing the smoke oil in the oil storage chamber 12 from leaking from between the airway structure 21 and the atomizer core 24.

[0127] Alternatively, see Figures 1 to 26 The atomizing device further comprises a splitter plate 20, which is disposed in the housing 1 and located between the atomizing assembly 2 and the air inlet 151;

[0128] The diverter plate 20 includes a diverter body 201 and a diverter hole 202 . The diverter hole 202 is disposed on the diverter body 201 . The diverter body 201 is opposite to the air inlet hole 151 , and the diverter hole 202 is opposite to the atomizer core 24 .

[0129] Specifically, since at least part of the atomizer core 24 is offset from the air inlet 151, in order to facilitate the airflow entering from the air inlet 151 to be fully mixed with the smoke atomized by the atomizer core 24 and effectively carry the atomized smoke to the air outlet channel 11, the diverter body 201 can be opposite to the air inlet 151, and the diverter hole 202 can be opposite to the atomizer core 24, so that the airflow entering from the air inlet 151 is blocked by the diverter body 201 and then flows to the diverter hole 202, and then flows to the atomization area corresponding to the atomizer core 24 through the diverter hole 202, and finally, after the air intake airflow and the atomized smoke are fully mixed, a mixed airflow is formed, and the mixed airflow carries the atomized smoke to the air outlet channel 11, thereby increasing the content of atomized smoke in the mixed airflow and ensuring the smoking taste of the electronic cigarette equipped with the atomizer device.

[0130] Alternatively, see Figures 1 to 3 The housing 1 includes an upper shell 14 and a lower cover 15 that are relatively connected, the air outlet channel 11 is connected to the upper shell 14, and the air inlet hole 151 is provided on the lower cover 15;

[0131] The diverter plate 20 is fixedly connected to the lower cover 15 .

[0132] Specifically, the upper shell 14 and the lower cover can be detachably connected by snap-fitting or threaded connection, so as to facilitate the assembly of the atomizer assembly 2 and the splitter plate 20 and other components in the housing 1. When the air outlet channel 11 is connected to the upper shell 14 and the air inlet hole 151 is provided on the lower cover 15, the air outlet channel 11 and the air inlet hole 151 can be kept away from each other in the housing 1, thereby increasing the space for airflow to flow in the housing 1.

[0133] Alternatively, see Figures 4 to 9 The lower cover 15 is provided with an air inlet channel 152 , one end of the air inlet channel 152 is connected to the air inlet hole 151 , and at least a portion of the other end of the air inlet channel 152 abuts against the diverter plate 20 .

[0134] Specifically, after the external airflow flows into the air intake channel 152 from the air intake hole 151, it can flow to one side surface of the diverter plate 20 through the notch or through hole at the other end of the air intake channel 152, so that the intake airflow flows through the diverter hole 202 to the atomization area corresponding to the atomization core 24.

[0135] Furthermore, the cavity inside the lower cover 15 can be provided with a liquid absorption liquid 19. Specifically, the air inlet channel 152 can have two cavities in the lower cover 15, one cavity is provided with a first liquid absorption liquid 191, and the other cavity is provided with a second liquid absorption liquid 192. Both the first liquid absorption liquid 191 and the second liquid absorption liquid 192 have a liquid absorption surface facing the atomization chamber 13, so as to absorb the condensed smoke oil in the atomization chamber 13 and prevent the condensed smoke oil in the atomization chamber 13 from flowing out of the air inlet channel 152.

[0136] Alternatively, see Figures 1 to 5 The atomization assembly 2 is separated into an oil storage chamber 12 and an atomization chamber 13 in the shell 1, a flow chamber is provided between the diverter plate 20 and the lower cover 15, the other end of the air inlet channel 152 has a notch 153, the air inlet channel 152 is connected to the flow chamber through the notch 153, and the diverter hole 202 connects the flow chamber and the atomization chamber 13.

[0137] Specifically, when the other end of the air inlet channel 152 has a notch 153, part of the end surface of the other end of the air inlet channel 152 abuts against the diverter plate 20, and the remaining part of the end surface of the other end of the air inlet channel 152 forms the notch 153, so that the airflow in the air inlet channel 152 can flow unidirectionally to the flow cavity through the notch 153, thereby avoiding the multi-directional dispersion of the airflow in the air inlet channel 152 at the other end of the air inlet channel 152, thereby ensuring the stability of the airflow direction in the atomization device.

[0138] In one embodiment, an air flow hole may be formed at the other end of the air inlet channel 152. In this case, the other end of the air inlet channel 152 may be completely abutted against the diverter plate 20, and the air flow in the air inlet channel 152 flows to the flow cavity through the air flow hole.

[0139] In another embodiment, a guide groove is provided on one side of the diverter plate 20 close to the lower cover 15 so that the airflow of the air inlet channel 152 is transmitted to the diverter hole 202 through the guide groove, thereby avoiding the provision of a flow cavity and achieving the compactness and miniaturization of the atomization device.

[0140] Alternatively, see Fig. 22 The air inlet passage 152 is located at the center of the lower cover 15 .

[0141] Specifically, the air inlet channel 152 can be located at the center of the lower cover 15 in both the width direction and the thickness direction of the housing 1, so that the airflow outside the housing 1 flows evenly from the air inlet hole 151 into the air inlet channel 152. In addition, since the atomizer core 24 is offset in the housing 1, a tortuous path of the airflow can be formed in the process of the airflow in the air inlet channel 152 flowing to the flow cavity and the diverter hole 202, so as to flexibly adjust the suction resistance of the airflow.

[0142] Alternatively, see Figures 1 to 4 The atomization device further includes a conductive nail 16 . The lower cover 15 is provided with an assembly hole. The conductive nail 16 passes through the assembly hole and is electrically connected to the conductive sheet on the atomization core 24 .

[0143] Specifically, one end of the conductive nail 16 extending into the atomization chamber 13 can directly abut against the heating wire on the atomization core 24, or the conductive nail 16 can be connected to the heating wire on the atomization core 24 through a conductive spring sheet 17, so that the cigarette rod of the electronic cigarette can energize the heating wire through the conductive nail 16, thereby achieving rapid heating of the heating wire and ensuring the atomization effect of the heating wire on the tobacco oil.

[0144] Alternatively, see Figure 4 The conductive nail 16 includes a first conductive nail 161 , and the first conductive nail 161 is arranged opposite to the atomization core 24 .

[0145] Specifically, the first conductive nail 161 may include a first nail cap and a first nail body. When the first conductive nail 161 is assembled to the lower cover 15, the first nail cap is exposed to the outside of the lower cover 15 to facilitate electrical connection with the cigarette rod; and the first nail body is vertically connected to the first nail cap and extends in a straight line. When the first conductive nail 161 is arranged opposite to the atomizer core 24, the first conductive nail 161 can be directly connected to the heating wire on the atomizer core 24, thereby simplifying the structure and conductive path of the first conductive nail 161.

[0146] Alternatively, see Figures 4 to 9 The diverter plate 20 is provided with an avoidance hole 203 , and the first conductive nail 161 penetrates through the avoidance hole 203 and forms an airflow gap with the inner wall of the avoidance hole 203 .

[0147] Specifically, since the thickness of the diverter plate 20 is very small, in order to ensure the structural strength of the diverter plate 20 and simplify the molding process of the diverter plate 20, the diverter plate 20 can be set as a metal plate, and the air flow gap between the first conductive nail 161 and the inner wall of the avoidance hole 203 can prevent the diverter plate 20 from short-circuiting the first conductive nail 161.

[0148] Furthermore, the airflow gap cooperates with the diverter hole 202 to be used together to connect the flow cavity and the atomization cavity 13, thereby increasing the path for the airflow in the atomization device.

[0149] Alternatively, see Figure 4 , Figures 12 to 15 The atomization device further includes a conductive spring sheet 17 , and the conductive nail 16 includes a second conductive nail 162 . The second conductive nail 162 is staggered with the atomization core 24 and is electrically connected to the conductive sheet on the atomization core 24 through the conductive spring sheet 17 .

[0150] Specifically, the second conductive nail 162 may include a second nail cap and a second nail body. When the second conductive nail 162 is assembled to the lower cover 15, the second nail cap is exposed to the outside of the lower cover 15 to facilitate electrical connection with the cigarette rod; and the second nail body is vertically connected to the second nail cap and extends in a straight line. When the second conductive nail 162 and the atomization core 24 are staggered, the second conductive nail 162 can be connected by the conductive spring sheet 17 while abutting against the heating wire on the atomization core 24, thereby ensuring the stability of conduction between the second conductive nail 162 and the heating wire on the atomization core 24.

[0151] In addition, one of the first conductive nail 161 and the second conductive nail 162 is a positive conductive nail, and the other is a negative conductive nail.

[0152] Alternatively, see Figures 4 to 9 The lower cover 15 is provided with a positioning post 154 , the conductive spring sheet 17 is sleeved on the positioning post 154 , and at least a portion of the diverter plate 20 is sandwiched between the conductive spring sheet 17 and the lower cover 15 .

[0153] Specifically, a first positioning hole 204 is provided on the diverter plate 20, the conductive spring sheet 17 includes a substrate 173 and an elastic sheet 174, a second positioning hole 171 and an abutment groove 172 are provided on the substrate 173, the elastic sheet 174 is electrically connected to the conductive sheet on the atomization core 24, and the conductive spring sheet 17 is fixed to the lower cover 15 by riveting through the substrate 173; at least part of the diverter plate 20 is assembled between the conductive spring sheet 17 and the lower cover 15, for example, at least part of the diverter plate 20 is clamped and fixed between the conductive spring sheet 17 and the lower cover 15, so as to achieve a seal between at least part of the diverter plate 20 and the lower cover 15, and prevent condensate from leaking from the mating surface of the diverter plate and the lower cover into the air inlet 151.

[0154] Alternatively, see Fig.10 and Fig.11 The diverter plate 20 includes a plurality of diverter holes 202 , and the plurality of diverter holes 202 are arranged in an array on the diverter body 201 .

[0155] Specifically, the opening size and the number of the diverter holes 202 are directly related to the suction resistance formed by the diverter plate 20. For example, the more the number of the diverter holes 202 is, the smaller the suction resistance formed by the diverter plate 20 is, and the fewer the number of the diverter holes 202 is, the larger the suction resistance formed by the diverter plate 20 is. That is, the suction resistance formed by the diverter plate 20 can be flexibly adjusted by adjusting the number of the diverter holes 202 on the diverter body 201 to ensure that the intake airflow and the atomized smoke are fully mixed.

[0156] Specifically, see Figures 1 to 4 The atomizer assembly 2 includes a ventilation channel 22, and a lower cover seal 18 is arranged on the periphery of the lower cover 15, and the lower cover seal 18 is used to seal the gap between the upper shell 14 and the lower cover 15; the periphery of the airway structure 21 is provided with a ventilation groove 211 embedded in the airway structure 21, and at least part of the ventilation channel 22 is formed in the ventilation groove 211.

[0157] Specifically, when the airway structure 21 is arranged between the air outlet channel 11 and the shell 1, a ventilation groove 211 may be provided on the side of the airway structure 21 facing the air outlet channel 11 to form at least a partial ventilation channel 22 between the airway structure 21 and the air outlet channel 11; or a ventilation groove 211 is provided on the side of the airway structure 21 facing the shell 1 to form at least a partial ventilation channel 22 between the airway structure 21 and the shell 1 to ensure the gas phase balance between the atomization chamber 13 and the oil storage chamber 12.

[0158] The embodiment of the present application further provides an electronic cigarette, which includes the atomization device.

[0159] Specifically, the electronic cigarette includes a cigarette rod, and the atomizer is electrically connected to an electrical component of the cigarette rod through a conductive nail. The electrical component can supply power to the heating wire of the atomizer through the conductive nail to achieve conversion of electrical energy and thermal energy in the heating wire.
