[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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:

[0052] 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;

[0053] an atomizer assembly 2, wherein the atomizer assembly 2 is disposed in the accommodating chamber and divides the accommodating chamber into an oil storage chamber 12 and an atomizing chamber 13, wherein the oil storage chamber is used to store an aerosol matrix, the atomizer assembly 2 comprises an atomizer core 24 and a ventilation structure 21, wherein the atomizer core 24 is used to atomize the aerosol matrix to release the aerosol toward the atomizing chamber, the ventilation structure 21 is disposed between the air outlet channel 11 and the housing 1, and the ventilation structure 21 has at least a portion of a ventilation channel 22;

[0054] 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 .

[0055] 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 size of the housing 1 in the width direction is greater than the size of the housing 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 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 in the length direction of the housing 1.

[0056] 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 is provided on the housing 1 .

[0057] 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, 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 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.

[0058] 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.

[0059] When the ventilation structure 21 is arranged between the air outlet channel 11 and the shell 1, for example, the ventilation structure 21 can be clamped between the outer wall of the air outlet channel 11 and the inner wall of the shell 1, or the ventilation structure 21 is bonded between the outer wall of the air outlet channel 11 and the inner wall of the shell 1. While ensuring that the tobacco oil in the oil storage chamber 12 flows smoothly to the atomization component 2 to avoid the problem of tobacco oil burning, it can also prevent the influence of ventilation on the air outlet, thereby improving the atomization stability and efficiency of the electronic cigarette and ensuring the user experience.

[0060] The atomization device provided in the embodiment of the present application includes a shell 1, an air outlet channel 11 is provided in the shell 1, and a accommodating chamber is formed in the shell 1; an atomization component 2, the atomization component 2 includes a ventilation structure 21, the atomization component 2 is arranged in the accommodating chamber and divides the accommodating chamber into an oil storage chamber 12 and an atomization chamber 13, the ventilation structure 21 is arranged between the air outlet channel 11 and the shell 1, and the ventilation structure 21 has at least a part of the ventilation channel 22; 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 ventilation channel 22 is configured to connect the atomization chamber 13 and the oil storage chamber 12, so as to ensure that the tobacco oil in the oil storage chamber 12 flows smoothly to the atomization component 2, avoid the problem of tobacco oil burning, and prevent the influence of ventilation on the air outlet, thereby improving the atomization stability and atomization efficiency of the electronic cigarette.

[0061] Alternatively, see Figures 10 to 14The outer periphery of the ventilation structure 21 is provided with a ventilation groove 211 embedded in the ventilation structure 21 , and at least a part of the ventilation channel 22 is formed in the ventilation groove 211 .

[0062] 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.

[0063] Alternatively, see Fig.10 and Fig.11 The ventilation groove 211 includes a first ventilation groove and a second ventilation groove. The first ventilation groove is located on a side of the ventilation structure 21 close to the shell 1 , and the second ventilation groove is located on a side of the ventilation groove 211 close to the oil storage chamber 12 .

[0064] Specifically, the first section of the ventilation groove is located on the side of the ventilation structure 21 close to the housing 1 and can extend along the length direction of the housing 1. Since the oil storage chamber 12 and the atomization chamber 13 are arranged along the length direction of the atomization device, that is, Figure 1 When the first section of the ventilation groove extends along the length direction, the second section of the ventilation groove may include an extension along a plane perpendicular to the length direction, so that the ventilation channel 22 may extend in a fold line in the plane along the length direction, or may extend in a fold line in the plane perpendicular to the length direction, and the pressure of the set threshold value is adjusted by the bending position formed by the ventilation channel 22 in the fold line extension process to ensure the atomization effect of the atomization device.

[0065] The bending position formed by the ventilation channel 22 extending in a folded line can be a right angle, or an acute angle or an obtuse angle close to a right angle. The bending position formed by the ventilation channel 22 extending in a folded line can effectively collide with the airflow flowing from the atomization chamber 13 to the oil storage chamber 12, and while changing the direction of the airflow, flexibly adjust the air pressure difference between the atomization chamber 13 and the oil storage chamber 12 to open the set threshold of the ventilation channel 22.

[0066] Optionally, the first section of the ventilation groove has at least one bending position.

[0067] Specifically, when the first section of the ventilation groove only extends along the length direction of the atomization device, in order to avoid forming a straight ventilation channel 22, the ventilation channel 22 can be bent once or multiple times in the plane along the length direction to achieve flexible adjustment of the set threshold value. When the first section of the ventilation groove extends along both the length direction and the plane perpendicular to the length direction, that is, the first section of the ventilation groove has been bent once to form a bending position when it turns from the length direction to the plane perpendicular to the length direction. The first section of the ventilation groove can extend in a straight line in the length direction and in the plane perpendicular to the length direction, or it can be bent separately to form a bending position. In the case where the first section of the ventilation groove has multiple bending positions, the size of the set threshold can be further adjusted.

[0068] Optionally, the ventilation groove 211 has a first opening and a second opening, the first opening is located on a side of the ventilation structure 21 close to the atomization chamber 13 , and the second opening is located on a side of the ventilation structure 21 close to the oil storage chamber 12 .

[0069] Specifically, the ventilation groove 211 can extend from the first opening to the second opening. When the first opening is located on the side of the ventilation structure 21 close to the atomization chamber 13 and the second opening is located on the side of the ventilation structure 21 close to the oil storage chamber 12, the atomization chamber 13 and the oil storage chamber 12 can be connected through the ventilation channel 22 formed by the ventilation groove 211, so that the air in the atomization chamber 13 can flow into the oil storage chamber 12, thereby ensuring the air pressure balance between the atomization chamber 13 and the oil storage chamber 12.

[0070] Alternatively, see Figures 10 to 14 The ventilation structure 21 has a hollow cavity 212 therein, and the hollow cavity 212 is connected to the atomization cavity 13 .

[0071] Specifically, the hollow cavity 212 may have an opening toward the atomization cavity 13, and the hollow cavity 212 is connected to the atomization cavity 13 through the opening. 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.

[0072] Optionally, a communication hole is provided on the ventilation structure 21 , and the hollow cavity 212 is connected with the ventilation groove 211 through the communication hole.

[0073] Specifically, when the hollow cavity 212 is connected to the ventilation groove 211 through the connecting hole, the gas replenished by the atomizer chamber 13 to the oil storage chamber 12 can first be gathered through the hollow cavity 212, and then the gas is replenished to the oil storage chamber 12 through the ventilation channel 22 formed by the ventilation groove 211, thereby ensuring that the smoke oil in the oil storage chamber 12 flows smoothly to the atomizer assembly 2.

[0074] In another embodiment, the hollow cavity 212 can be arranged inside the ventilation structure 21 and surrounded by the physical structure of the ventilation structure 21, and the ventilation groove 211 includes an air inlet section and an air outlet section, the air inlet section connects the atomization chamber 13 and the hollow cavity 212, and the air outlet section connects the hollow cavity 212 and the oil storage chamber 12, that is, a ventilation channel 22 consisting of the air inlet section, the hollow cavity 212 and the air outlet section is formed, and the ventilation can also be adjusted through the hollow cavity 212.

[0075] Alternatively, see Figure 1 and Fig.15 The atomization assembly 2 includes a sealing member 23 , at least a portion of which is disposed around the ventilation structure 21 , and the sealing member 23 and the ventilation groove 211 are combined to form the ventilation channel 22 .

[0076] Specifically, the 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 seal 23, the 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.

[0077] Optionally, the cross-section of the ventilation channel 22 is rectangular, square, semicircular or trapezoidal.

[0078] 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.

[0079] Alternatively, see Figures 15 to 17 , 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 ;

[0080] 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;

[0081] 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.

[0082] 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.

[0083] 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.

[0084] Optionally, the ventilation channel 22 is a ventilation through hole provided in the ventilation structure 21 .

[0085] 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.

[0086] Optionally, the ventilation structure 21 is sandwiched between the air outlet channel 11 and the shell 1 .

[0087] Specifically, when the ventilation structure 21 is sandwiched between the outer wall of the air outlet channel 11 and the inner wall of the shell 1, the detachable ventilation structure 21 can separate at least part of the oil storage chamber 12 and the atomization chamber 13, thereby ensuring that the oil in the oil storage chamber 12 flows smoothly to the atomization assembly 2 to avoid the problem of oil burning, and preventing the influence of ventilation on the air outlet, thereby improving the atomization stability and efficiency of the electronic cigarette and ensuring the user experience.

[0088] Alternatively, see Figure 1 and Figure 2 The atomizer assembly 2 further includes a sealing member 23 . The atomizer core 24 is disposed between the air outlet channel 11 and the housing 1 , and at least a portion of the sealing member 23 is disposed around the atomizer core 24 .

[0089] Specifically, a sealing rib 232 is provided on the outer periphery of the sealing member 23, and the sealing member 23 can seal the assembly gap between the housing 1 and the atomization core 24 through the sealing rib 232, and the atomization 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 sealing member 23.

[0090] Optionally, the atomization device further includes a first conductive nail 161 and a second conductive nail 162, wherein the first conductive nail 161 is arranged opposite to the atomization core 24 and is electrically connected to a first conductive sheet on the atomization core 24, and the second conductive nail 162 is arranged offset from the atomization core 24 and is electrically connected to a second conductive sheet on the atomization core 24 through a conductive spring sheet 17.

[0091] See also Figure 1 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 the lower cover 15 is provided with a conductive nail 16, the conductive nail 16 includes a first conductive nail 161 and a second conductive nail 162, and one end of the first conductive nail 161 extending into the atomization chamber 13 can directly abut against the first conductive sheet 244 at both ends of the heating wire 243 on the atomization core 24, and the second conductive nail 162 is connected to the second conductive sheet 244 at both ends of the heating wire 243 on the atomization core 24 through a conductive spring sheet 17; so as to energize the heating wire 243 and realize rapid heating of the heating wire 243.
