DETAILED DESCRIPTION

[0077] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0078] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0079] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0080] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0081] 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.

[0082] Reference Figures 1 to 3 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:

[0083] A housing 1, wherein an air outlet passage 11 is provided in the housing 1, and a receiving cavity is formed in the housing 1;

[0084] An atomizer assembly 2 is disposed in the accommodating chamber, wherein the atomizer assembly 2 separates the accommodating chamber into an oil storage chamber 12 and an atomization chamber 13 in the accommodating chamber, wherein the oil storage chamber is used to store an aerosol matrix, and wherein the atomizer assembly 2 comprises an atomizer core 24, wherein the atomizer core 24 is used to atomize the aerosol matrix to release the aerosol toward the atomization chamber, and wherein the atomizer core 24 is clamped between the air outlet channel 11 and the shell 1.

[0085] Specifically, the size of the housing 1 in the length direction is greater than the size of the housing 1 in the width direction and the thickness direction. The length direction (first direction), the width direction (second direction) and the thickness direction (third direction) may be the X direction, the Y direction and the Z direction in the figure, respectively. The air outlet channel 11 may be provided in the housing 1 along the length direction of the housing 1 to form an air outlet path of the housing 1 in the length direction.

[0086] The air outlet channel 11 can be suspended in the shell 1, so that an assembly space is formed between the air outlet channel 11 and the shell 1, and the atomizer core 24 is clamped between the air outlet channel 11 and the shell 1, for example, the atomizer core 24 is clamped between the air outlet channel 11 and the shell 1, or the atomizer core 24 is clamped between the air outlet channel 11 and the shell 1 through an interference fit of a seal.

[0087] When the atomizer core 24 is arranged between the air outlet channel 11 and the shell 1, it is possible to avoid providing an atomizer core bracket in the shell 1. On the basis of ensuring the stability of the arrangement of the atomizer core 24, the structure of the atomizer device is simplified, and the atomizer device is miniaturized and thinned.

[0088] The atomizer device provided in the embodiment of the present application includes a shell 1, in which an air outlet channel 11 is provided, and a accommodating cavity is formed in the shell 1; an atomizer assembly 2, which is arranged in the accommodating cavity, and the atomizer assembly 2 includes an atomizer core 24, and the atomizer core 24 is arranged between the air outlet channel 11 and the shell 1. On the basis of ensuring the stability of the arrangement of the atomizer core 24, the structure of the atomizer device is simplified.

[0089] Alternatively, see Figure 1 , the atomizing assembly 2 has at least a portion of the ventilation channel 22;

[0090] 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 ventilation channel 22 is configured to communicate with the atomizing chamber 13 and the oil storage chamber 12 .

[0091] Specifically, the ventilation channel 22 is used to balance the air pressure between the oil storage chamber 12 and the atomization chamber 13 , and an air inlet hole is provided on the housing 1 .

[0092] Under normal conditions, that is, when the gas phase pressure difference between the atomization chamber 13 and the oil storage chamber 12 is less than a set threshold value, since the atomization chamber 13 is connected to the outside through the air inlet hole, 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 component 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 its surface tension, 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.

[0093] When the gas phase 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.

[0094] Optionally, the ventilation channel 22 is located between the atomizer core 24 and the housing 1 .

[0095] Specifically, when the atomizer core 24 is arranged between the air outlet channel 11 and the shell 1, the atomizer core 24 can be isolated from at least part of the space between the atomizer chamber 13 and the oil storage chamber 12; when the ventilation channel 22 is located between the atomizer core 24 and the shell 1, it is convenient to open the ventilation channel 22 to allow the air in the atomizer chamber 13 to flow into the oil storage chamber 12 when the gas phase pressure difference between the atomizer chamber 13 and the oil storage chamber 12 is greater than or equal to the set pressure, thereby achieving rapid balance of the air pressure between the oil storage chamber 12 and the atomizer chamber 13.

[0096] Alternatively, see Figures 15 to 17 The atomizer assembly 2 includes a first seal 23, at least a portion of which is sandwiched between the atomizer core 24 and the housing 1;

[0097] The first sealing member 23 is provided with a first ventilation groove, and at least a portion of the ventilation channel 22 is formed in the first ventilation groove.

[0098] Specifically, when at least a portion of the first sealing member 23 is sandwiched between the atomizer core 24 and the housing 1 , the first sealing member 23 can be used to seal the gap between the atomizer core 24 and the housing 1 , thereby ensuring the relative independence of the oil storage chamber 12 and the atomization chamber 13 .

[0099] When the gas phase pressure difference between the atomization chamber 13 and the oil storage chamber 12 is greater than or equal to the set pressure, the first ventilation groove provided on the first sealing member 23 can connect the oil storage chamber 12 and the atomization chamber 13, and at least a part of the ventilation channel 22 is formed in the first ventilation groove, so that the air in the atomization chamber 13 can supplement the air pressure in the oil storage chamber 12 through the ventilation channel 22.

[0100] Optionally, the first ventilation groove is provided on one side of the first sealing member 23 close to the housing 1, and the housing 1 and the first ventilation groove form the ventilation channel 22;

[0101] Alternatively, the first ventilation groove is disposed on one side of the first sealing member 23 close to the atomizer core 24 , and the atomizer core 24 and the first ventilation groove form the ventilation channel 22 .

[0102] Specifically, since the first sealing member 23 is sandwiched between the atomizer core 24 and the shell 1, when the ventilation channel 22 is located between the atomizer core 24 and the shell 1, the ventilation channel 22 can be formed by cutting a groove on the first sealing member 23. For example, the first ventilation groove is obtained integrally when the first sealing member 23 is molded, thereby simplifying the preparation process of the atomizer device.

[0103] In one embodiment, a first ventilation groove is provided on the side of the first sealing member 23 close to the shell 1, and the first ventilation groove has an opening toward the shell 1. When the shell 1 abuts against the first sealing member 23, a ventilation channel 22 can be formed between the shell 1 and the inner wall of the first ventilation groove.

[0104] In another embodiment, a first ventilation groove is provided on one side of the first sealing member 23 close to the atomizer core 24. The first ventilation groove has an opening toward the atomizer core 24. When the atomizer core 24 abuts against the first sealing member 23, a ventilation channel 22 can be formed between the atomizer core 24 and the inner wall of the first ventilation groove.

[0105] Optionally, a second ventilation groove is provided on one side of the housing 1 close to the atomizer core 24 , and the atomizer core 24 and the second ventilation groove form the ventilation channel 22 .

[0106] Specifically, the shell 1 can be a shell formed of hard plastic or hard resin to ensure the structural stability of the shell 1; when a second ventilation groove is provided on a side of the shell 1 close to the atomizer core 24, structural deformation of the second ventilation groove can be avoided; the atomizer core 24 and the second ventilation groove surround the ventilation channel 22, ensuring the dimensional accuracy of the ventilation channel 22.

[0107] It is worth noting that when the atomizer core 24 and the second ventilation groove form the ventilation channel 22, that is, a side wall of the ventilation channel 22 is formed on the atomizer core 24, and the atomizer assembly 2 includes the atomizer core 24, so that at least a part of the ventilation channel 22 is provided on the atomizer assembly 2.

[0108] Optionally, a third ventilation groove is provided on a side of the atomizer core 24 close to the shell 1 , and the shell 1 and the third ventilation groove form the ventilation channel 22 .

[0109] Specifically, the atomizer core 24 can be an atomizer core formed of hard ceramics to ensure the structural stability of the atomizer core 24. At the same time, the channels in the ceramic structure can be used to facilitate the penetration of the e-liquid. When a third ventilation groove is provided on the side of the atomizer core 24 close to the shell 1, structural deformation of the third ventilation groove can be avoided. The shell 1 and the third ventilation groove form the ventilation channel 22, which can also ensure the dimensional accuracy of the ventilation channel 22.

[0110] Optionally, the ventilation channel 22 is located between the atomization core 24 and the air outlet channel 11 .

[0112] Optionally, the atomizer assembly 2 includes a second sealing member, at least a portion of which is sandwiched between the atomizer core 24 and the air outlet channel 11;

[0113] The second sealing member is provided with a fourth ventilation groove, and at least a portion of the ventilation channel 22 is formed in the fourth ventilation groove.

[0114] Specifically, when at least a portion of the second sealing member is sandwiched between the atomizer core 24 and the air outlet channel 11 , the second sealing member can be used to seal the gap between the atomizer core 24 and the air outlet channel 11 , thereby ensuring the relative independence of the oil storage chamber 12 and the atomization chamber 13 .

[0115] When the gas phase pressure difference between the atomization chamber 13 and the oil storage chamber 12 is greater than or equal to the set pressure, the fourth ventilation groove provided on the second sealing member can connect the oil storage chamber 12 and the atomization chamber 13, and at least a part of the ventilation channel 22 is formed in the fourth ventilation groove, so that the air in the atomization chamber 13 can supplement the air pressure in the oil storage chamber 12 through the ventilation channel 22.

[0116] Optionally, the fourth ventilation groove is provided on one side of the second sealing member close to the air outlet channel 11, and the air outlet channel 11 and the fourth ventilation groove form the ventilation channel 22;

[0117] Alternatively, the fourth ventilation groove is disposed on a side of the second sealing member close to the atomizer core 24 , and the atomizer core 24 and the fourth ventilation groove form the ventilation channel 22 .

[0118] Specifically, since the second sealing member is sandwiched between the atomizer core 24 and the air outlet channel 11, when the ventilation channel 22 is located between the atomizer core 24 and the air outlet channel 11, the ventilation channel 22 can be formed by cutting a groove on the second sealing member. For example, a fourth ventilation groove can be obtained integrally when the second sealing member is molded, thereby simplifying the preparation process of the atomizer device.

[0119] In one embodiment, a fourth ventilation groove is provided on the side of the second sealing member close to the air outlet channel 11, and the fourth ventilation groove has an opening toward the air outlet channel 11.

[0121] Optionally, a fifth ventilation groove is provided on one side of the air outlet channel 11 close to the atomizer core 24 , and the atomizer core 24 and the fifth ventilation groove form the ventilation channel 22 .

[0124] Specifically, the atomizer core 24 can be an atomizer core formed of hard ceramics to ensure the structural stability of the atomizer core 24. At the same time, the channels in the ceramic structure can be used to facilitate the penetration of the e-liquid. When the sixth ventilation groove is provided on the side of the atomizer core 24 close to the air outlet channel 11, structural deformation of the sixth ventilation groove can be avoided. The air outlet channel 11 and the sixth ventilation groove surround the ventilation channel 22, which can also ensure the dimensional accuracy of the ventilation channel 22.

[0125] Alternatively, see Figures 1 to 3 , the air outlet channel 11 is arranged in the shell 1 along the length direction of the shell 1;

[0126] The dimension of the shell 1 in the length direction is greater than the dimension of the shell 1 in the width direction, and the dimension of the shell 1 in the width direction is greater than the dimension of the shell 1 in the thickness direction.

[0132] In one embodiment, the shell 1, the ventilation structure 21 and the atomizer core 24 can be hard structures, and the sealing member can be a soft structure; when the atomizer core 24 is sandwiched between the air outlet channel 11 and the shell 1 by the interference fit of the sealing member, the gap between the atomizer core 24 and the air outlet channel 11, and the gap between the atomizer core 24 and the shell 1 can be sealed by the deformation of the sealing member.

On the basis of increasing the space of the atomization cavity 13, the weight of the ventilation structure 21 can be reduced, thereby achieving the purpose of lightweight setting of the atomization component 2.

[0135] Optionally, at least a portion of the first sealing member 23 is disposed on the ventilation structure 21 , and the first sealing member 23 and the ventilation groove 211 are combined to form the ventilation channel 22 .

[0136] Specifically, the first seal 23 is sandwiched between the shell 1 and the ventilation structure 21. On the basis of sealing the assembly gap between the shell 1 and the ventilation structure 21 by the first seal 23, the first seal 23 and the ventilation groove 211 are enclosed to form the ventilation channel 22, thereby ensuring the stability of ventilation between the atomization chamber 13 and the oil storage chamber 12.

[0138] 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;

[0139] 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.

[0140] 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.

[0141] 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.

[0142] Furthermore, a sealing rib 232 is provided on the outer periphery of the first sealing member 23 , and the first sealing member 23 can seal the assembly gap between the housing 1 and the atomizer core 24 through the sealing rib 232 .

[0143] Optionally, the atomizer assembly 2 includes a third sealing member and a fourth sealing member, wherein the third sealing member is located in the first space and is sandwiched between the atomizer core 24 and the air outlet channel 11, and between the atomizer core 24 and the housing 1;

[0144] The fourth sealing member is located in the second space and is sandwiched between the air outlet channel 11 and the housing 1 .

[0145] Specifically, through the cooperation of the third sealing member and the fourth sealing member, the accommodating chamber can be divided into two independent oil storage chambers 12 and atomization chamber 13 , thereby preventing the smoke oil in the oil storage chamber 12 from leaking into the atomization chamber 13 .

[0146] Alternatively, see Figures 1 to 3 The atomizer core 24 has a liquid suction surface 241 facing the oil storage chamber 12 and an atomization surface 242 facing the atomization chamber 13, and both the liquid suction surface and the atomization surface are exposed from the first sealing member 23, so that the smoke oil in the oil storage chamber 12 can penetrate into the atomization surface 242 through the liquid suction surface 241.

[0147] Optionally, the shell 1 includes an upper shell 14 and a lower cover 15, the lower cover 15 is provided with an air inlet hole 151, and a conductive nail 16 is provided in the lower cover 15. One end of the conductive nail 16 extending into the atomization chamber 13 can directly abut against the heating wire 243 on the atomization core 24, or be connected to the heating wire 243 on the atomization core 24 through a conductive spring sheet 17.

[0148] Optionally, a lower cover seal 18 is provided on the outer 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; a liquid suction 19 and a diverter plate 20 are provided on the side of the atomization chamber 13 close to the lower cover 15; the air outlet channel 11 is provided in the upper shell 14, and a support rib 141 is provided in the upper shell 14, and the support rib 141 is used to support the atomization assembly 2, and a buckle 142 is provided in the upper shell 14, and the setting of the buckle 142 can facilitate the buckle connection with the hook on the lower cover 15, thereby ensuring the stability of the detachable connection between the upper shell 14 and the lower cover 15.

[0149] Optionally, the atomization assembly 2 includes a ventilation structure 21 , and at least a portion of the ventilation channel 22 is formed on the ventilation structure 21 .

[0150] Specifically, the ventilation channel 22 can balance the air pressure between the oil storage chamber 12 and the atomization chamber 13, and the ventilation structure 21 can be located between the oil storage chamber 12 and the atomization chamber 13; when at least part of the ventilation channel 22 is formed on the ventilation structure 21, the oil storage chamber 12 and the atomization chamber 13 can be isolated when the gas phase pressure difference between the atomization chamber 13 and the oil storage chamber 12 is less than a set threshold value, thereby preventing the liquid in the oil storage chamber 12 from entering the atomization chamber 13.

[0151] When the gas phase pressure difference between the atomizing chamber 13 and the oil storage chamber 12 is greater than or equal to the set pressure, the ventilation channel 22 is opened to directly connect the atomizing chamber 13 and the oil storage chamber 12, so that the air in the atomizing chamber 13 flows into the oil storage chamber 12, thereby ensuring the air pressure balance between the atomizing chamber 13 and the oil storage chamber 12.

[0152] Optionally, a ventilation groove 211 embedded in the ventilation structure 21 is provided on the periphery of the ventilation structure 21 , and at least a portion of the ventilation channel 22 is formed in the ventilation groove 211 .

[0153] Specifically, when the ventilation structure 21 is arranged between the air outlet channel 11 and the shell 1, a ventilation groove 211 is provided on the side of the ventilation structure 21 facing the air outlet channel 11 to form at least a partial ventilation channel 22 between the ventilation structure 21 and the air outlet channel 11; or a ventilation groove 211 is provided on the side of the ventilation structure 21 facing the shell 1 to form at least a partial ventilation channel 22 between the ventilation structure 21 and the shell 1 to ensure the gas phase balance between the atomization chamber 13 and the oil storage chamber 12.

[0154] Alternatively, see Figure 1 and Fig.15 The atomizer assembly 2 includes a first seal 23 , at least a portion of which is disposed around the ventilation structure 21 , and the first seal 23 and the ventilation groove 211 are combined to form the ventilation channel 22 .

[0155] Specifically, the first seal 23 is sandwiched between the shell 1 and the ventilation structure 21. On the basis of sealing the assembly gap between the shell 1 and the ventilation structure 21 by the first seal 23, the first seal 23 and the ventilation groove 211 are enclosed to form the ventilation channel 22, thereby ensuring the stability of ventilation between the atomization chamber 13 and the oil storage chamber 12.

[0156] Optionally, the cross-section of the ventilation channel 22 is rectangular, square, semicircular or trapezoidal.

[0157] Specifically, the cross-sectional shape, cross-sectional area and effective length of the ventilation channel 22 are also directly related to the pressure of the set threshold. For example, when the cross-sectional area of ​​the ventilation channel 22 is small, the pressure of the set threshold can be increased accordingly; and when the effective length of the ventilation channel 22 increases, the pressure of the set threshold will increase accordingly. In other words, the pressure of the set threshold can also be adjusted by changing the cross-sectional shape, cross-sectional area and effective length of the ventilation channel 22.

[0158] Alternatively, see Figures 15 to 17 , the first 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;

[0159] 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;

[0160] 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.

[0161] 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.

[0162] 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 to block the ventilation channel 22 through a pressure difference greater than or equal to the set threshold, 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, and ensuring the air pressure balance between the atomization chamber 13 and the oil storage chamber 12.

[0163] Optionally, the ventilation channel 22 is a ventilation through hole provided in the ventilation structure 21 .

[0164] Specifically, the ventilation channel 22 is a ventilation through hole arranged in the ventilation structure 21 and passing through the ventilation structure 21. One end of the ventilation through hole is opened to connect to the atomization chamber 13, and the other end of the ventilation through hole is opened to connect to the oil storage chamber 12. When the pressure difference between the atomization chamber 13 and the oil storage chamber 12 is greater than or equal to a set threshold, the air in the atomization chamber 13 can flow into the oil storage chamber 12 through the ventilation through hole, thereby simplifying the structure of the ventilation channel 22.

[0165] Optionally, a splitter plate 20 is further included, the shell 1 is provided with an air inlet hole 151 and an air inlet channel 152, the splitter plate 20 is arranged in the shell 1 and is located between the atomizing core 24 and the air inlet hole 151, the splitter plate 20 is provided with a splitter hole 202, and the splitter hole 202 is opposite to the atomizing core 24;

[0166] A flow cavity is provided between the diverter plate 20 and the shell 1 , and the other end of the air inlet channel 152 has a notch 153 facing the diverter plate 20 . The air inlet channel 152 is connected to the flow cavity through the notch 153 , and the diverter hole 202 connects the flow cavity and the atomization cavity 13 .

[0167] Specifically, since the diverter hole 202 is opposite to the atomizer core 24, the airflow entering from the air inlet 151 flows through the diverter hole 202 to the atomization area corresponding to the atomizer core 24, and finally the air intake airflow and the atomized smoke are fully mixed to form a mixed airflow, and the mixed airflow carries the atomized smoke to the air outlet channel 11, thereby increasing the content of the atomized smoke in the mixed airflow and ensuring the smoking taste of the electronic cigarette equipped with the atomizer device.

[0168] 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.

[0169] 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.

[0170] 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.

[0171] Optionally, a conductive nail 16 is further included. A avoidance hole 203 is provided on the diverter plate 20 . The conductive nail 16 passes through the avoidance hole 203 and is electrically connected to the conductive sheet on the atomization core 24 .

[0172] 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.

[0173] 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 conductive nail 16 and the inner wall of the avoidance hole 203 can prevent the diverter plate 20 from short-circuiting the conductive nail 16.

[0174] 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.

[0175] Optionally, the diverter plate 20 includes a diverter body 201 and a plurality of diverter holes 202 , the diverter body 201 is opposite to the air inlet hole 151 , and the plurality of diverter holes 202 are arranged in an array on the diverter body 201 and are all opposite to the atomizer core 24 .

[0176] Specifically, 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 to 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.

[0177] 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 greater 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.

[0178] Optionally, the air outlet channel 11 includes a channel body and a flange located on a peripheral side of the channel body, and the flange abuts against the atomization assembly 2 .

[0179] Specifically, when the air outlet channel 11 is connected to the atomization chamber and the external space of the atomization device, the flange can be abutted against the atomization assembly 2 to achieve positioning of the air outlet channel 11, thereby ensuring the stability of the arrangement of the air outlet channel 11.

[0180] Optionally, the flange has at least a portion of a ventilation channel 22;

[0181] 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 ventilation channel 22 is configured to communicate with the atomizing chamber 13 and the oil storage chamber 12 .

[0182] 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.

[0183] 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.

[0184] Optionally, the channel body comprises a straight airway segment 212 and an oblique airway segment 213 connected to each other, the straight airway segment 212 extends along the first direction, and the oblique airway segment 213 extends obliquely relative to the first direction;

[0185] The straight air passage section 212 is connected to the air outlet hole on the housing through the air outlet section, and the oblique air passage section 213 is connected to the atomization chamber 13 .

[0186] 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.

[0187] 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.

[0188] Optionally, the straight airway section 212 and the air outlet section are plug-fitted.

[0189] Specifically, the air outlet channel 11 can be integrally formed in the shell to simplify the assembly process of the atomization device; and when assembling the atomization component 2, the straight air channel section 212 can be plugged into the air outlet section to facilitate the assembly of the components in the air outlet channel 11.

[0190] Optionally, an airway structural seal 25 is further included, and the airway structural seal 25 is at least partially sandwiched between the straight airway section 212 and the air outlet section.

[0191] Specifically, the airway structural seal 25 is sleeved on the straight airway section 212, and the air outlet section can be inserted into the straight airway section 212 and clamped between the straight airway section 212 and the air outlet section through the airway structural seal 25, so as to seal the gap in the air outlet channel 11 through the airway structural seal 25 to ensure the sealing of the airflow channel.

[0192] The embodiment of the present application further provides an electronic cigarette, which includes the atomization device.

[0193] 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.
