[0003] In the related art, the heating element of the atomization module is wound and accommodated in the liquid guide, and is attached to the liquid guide by the tension of the heating element itself.

DETAILED DESCRIPTION

[0029] The technical solutions of the present application will be described in further detail below with specific embodiments in conjunction with the drawings. In the following embodiments, many details are described in order to make the present application better understood. However, those skilled in the art can easily recognize that some features can be omitted in different cases, or can be replaced by ingredients, materials, methods. In some cases, some operations related to the present application are not shown or described in the specification in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail according to the description in the specification and general technical knowledge in the art.

[0030] Please refer to Figure 1 In some embodiments of the present application, an atomization module 10 is provided, which is used in an atomizer 100 (as shown in Figure 5 , Figure 7 ).

[0031] The atomization module 10 comprises a flexible piece 1, a liquid guide piece 2, a heating piece 3, and a support 4. The flexible piece 1 is provided with opposite first and second surfaces, and a plurality of through hole regions penetrating the first and second surfaces, the through hole regions comprising at least one through hole 11, and the through hole regions are configured to allow the atomization substrate to pass.

[0032] The liquid guide 2 abuts against the second surface of the flexible member 1, and at least part of the liquid guide 2 encloses the via region, and the liquid guide 2 is configured to adsorb the atomized substrate.

[0033] The heating member 3 abuts against the side of the liquid guide 2 away from the flexible member 1, and the heating member 3 is used to heat the atomized substrate and generate aerosol.

[0034] The side of the liquid guide 2 abutting against the flexible member 1 is configured as a liquid inlet surface 21, and the side of the liquid guide 2 abutting against the heating member 3 is configured as an atomization surface 22, the atomized substrate enters the liquid guide 2 through the liquid inlet surface 21 and is transmitted to the atomization surface 22 by the liquid guide 2, and then is heated and atomized by the heating member 3.

[0035] The support 4 at least partially abuts against the periphery of the side of the heating member 3 away from the liquid guide 2, and the support 4 is configured to allow the aerosol to be discharged.

[0036] The flexible member 1 can be provided as a planar structure with elasticity, and the liquid guide 2 and the heating member 3 can be provided as planar structures that fit the planar structure of the flexible member 1. After the atomization module 10 is assembled, the heating member 3, the liquid guide 2, and the flexible member 1 are pressed and combined by the support 4.

[0037] In use, the atomized substrate flows to the liquid guide 2 through each via 11 in the via region of the flexible member 1, is adsorbed and transmitted by the liquid guide 2 to the atomization surface 22 and contacts the heating member 3, and then is heated to atomization and generates aerosol by the heating member 3, and the generated aerosol is discharged through the support 4.

[0038] The atomization module 10 provided by the present application can press and combine the planar structure of the heating member 3, the liquid guide 2, and the flexible member 1 by the support 4, and provide support for the periphery of the planar structure of the heating member 3, thereby avoiding the problems of local deformation, collapse, and warping of the heating member 3, improving the support strength of the heating member 3 and the stability and reliability of the planar contact between the heating member 3 and the liquid guide 2, avoiding the problems of local excessive heating of the atomized substrate by the heating member 3 and insufficient heating of the atomized substrate by the heating member 3, significantly reducing the risk of carbon deposition, paste core, flying liquid, and liquid leakage, reducing the suction resistance, improving the quality of the aerosol generated by atomization, and improving the user experience.

[0039] At the same time, the support 4 presses and combines the heating member 3, the liquid guide 2, and the flexible member 1, significantly improves the structural strength of the heating member 3, and is conducive to reducing the thickness of the heating member 3 and improving the atomization efficiency.

[0040] In addition, the atomization module 10 provided by the present application limits the ends of the liquid guide 2, the heating element 3 and the support 4 through the flexible piece 1. The flexible piece 1 itself has a certain elasticity and can elastically deform to a certain extent when subjected to a pressing force from the support 4, so that the heating element 3 can abut against the liquid guide 2 to the greatest extent, thereby ensuring that the heating element 3 and the liquid guide 2 form good contact during assembly. Moreover, the flexible piece 1 can also play a certain buffering role to significantly reduce the risk of deformation and loosening of the liquid guide 2, the heating element 3 and the support 4 due to accidental conditions such as bumps and drops during use.

[0041] In some embodiments, the flexible piece 1 is made of a flexible material, which can be selected from a silica gel material, a rubber material, a soft plastic material and the like, and the present application does not make any limitation thereon. The specific shape, size and thickness of the flexible piece 1 can be set according to the actual use requirements of the atomization module 10.

[0042] The via region is provided corresponding to the heating element 3, and the opening shape of the via 11 in the via region can be any one or more of a circular shape, an elliptical shape, a polygonal shape, a special shape and the like. The vias 11 can be uniformly arranged in the via region or non-uniformly arranged in the via region, and the present application does not make any limitation thereon, as long as the liquid inlet requirement of the liquid guide 2 can be met.

[0043] The support 4 can be a frame structure or a ring structure, and the present application does not make any limitation thereon, as long as it can abut against the periphery of the heating element 3 to press and combine the heating element 3, the liquid guide 2 and the flexible piece 1, and can make the generated aerosol exhaust.

[0044] In order to facilitate the understanding of the technical scheme of the present application, the length direction of the heating element 3 is defined as the X-axis direction, the width direction of the heating element 3 is defined as the Y-axis direction, and the thickness direction of the heating element 3 is defined as the Z-axis direction, wherein the Z-axis direction is consistent with the direction of gravity.

[0045] Please refer to Figure 1 In a specific embodiment, the flexible piece 1, the liquid guide 2 and the heating element 3 are all provided as rectangular planar structures with consistent outer peripheral contours, and the support 4 is provided as a rectangular ring structure capable of abutting against the periphery of the heating element 3.

[0046] In other embodiments, the flexible piece, the liquid guide and the heating element can also be provided as circular planar structures, elliptical planar structures, polygonal planar structures, special planar structures and the like with consistent outer peripheral contours, and the specific structure of the support can be set according to the structure of the flexible piece, the liquid guide and the heating element, and the present application does not make any limitation thereon, as long as the actual use requirements of the atomization module can be met.

[0047] Please refer to Figure 1In some embodiments, the heating element 3 includes at least two heating lines 311, and the heating lines 311 are connected by a plurality of connection portions 312 to form a grid-shaped grid area 31. At least part of the via area corresponds to the grid area 31, and at least part of the support 4 corresponding to the grid area 31 is a hollow structure 41 for discharging the generated aerosol.

[0048] The heating lines 311 are connected by a plurality of connection portions 312 to form a grid-shaped grid area 31, and the grid area 31 has higher strength, which ensures the consistency of the plane of the heating element 3 and guarantees the stability and reliability of the plane contact between the heating element 3 and the liquid guide 2 and the support 4. The plurality of heating lines 311 can be arranged side by side, which increases the number of heating lines 311 in the grid area 31 and is conducive to improving the heating efficiency of the heating element 3.

[0049] The shapes, sizes, and other characteristics of the heating lines 311 can be the same or different; the heating lines 311 on the heating element 3 can be arranged in two or more. The present application does not limit this, and it can meet the actual use requirements of the atomization module 10.

[0050] Please refer to Figure 1 In some embodiments, the heating lines 311 extend along a first direction, and at least two heat dissipation portions 32 are arranged on both sides of the grid area 31 and extend along a second direction. The first direction is perpendicular to the second direction.

[0051] In the present embodiment, the first direction is taken as the X-axis direction, and the second direction is taken as the Y-axis direction. The heating lines 311 extend along the first direction, i.e., the X-axis direction, and the heat dissipation portions 32 extend along the second direction, i.e., the Y-axis direction, so that the overall extension direction of the heating lines 311 is perpendicular to the overall extension direction of the heat dissipation portions 32. On the one hand, the grid area 31 of the heating element 3 can be further strengthened by the heat dissipation portions 32, the contact points between the support 4 and the peripheral edge of the heating element 3 are increased, and the stability and reliability of the plane contact between the heating element 3 and the liquid guide 2 and the support 4 are further improved. On the other hand, the heat of the grid-shaped grid area 31 can be transmitted to both sides through the heat dissipation portions 32, so as to avoid the excessive concentration of temperature in the local part of the heating element 3, which may cause local deformation, collapse, and warping, and further reduce the risk of carbon deposition, core paste, flying liquid, and liquid leakage of the atomization module 10.

[0052] In some embodiments, the grid area 31 includes at least one of a regular polygonal element, an irregular polygonal element, an arc element, and a heterogeneous element. That is, the grid area 31 can include only a regular or irregular polygonal element, only a regular or irregular arc element, or only a regular or irregular heterogeneous element. Alternatively, the grid area 31 can simultaneously include at least two of the above-mentioned polygonal element, arc element, and heterogeneous element.

[0053] In some embodiments, the heating lines 311 can be arranged to extend in a straight line form, the heating lines 311 extending in the straight line form have a relatively shorter extension path, and the heating efficiency is higher. The adjacent heating lines 311 are combined by the plurality of connecting portions 312 extending in the straight line form along the second direction to form a grid region 31 in a grid shape, and at this time, the grid region 31 has regular or irregular polygonal cells. The connecting portions 312 can be arranged to be uniformly distributed at equal intervals along the extension path of the heating line 311. The uniformly distributed connecting portions 312 enable the grid region 31 formed to have a plurality of uniformly distributed quadrilateral cells, and the uniformly distributed quadrilateral cells can ensure the heating uniformity of each part of the grid region 31.

[0054] The connecting portions 312 can also be arranged to be distributed at unequal intervals along the extension path of the heating line 311, for example, the interval between the connecting portions 312 close to the middle of the grid region 31 is relatively smaller, and the interval between the connecting portions 312 away from the middle of the grid region 31 is relatively larger. The smaller the interval between the connecting portions 312 close to the middle of the grid region 31, the smaller the length of the quadrilateral cell constituting the grid region 31 in the X-axis direction, and the greater the arrangement density, and the heat of the middle region of the heating element 3 can be quickly transferred to the adjacent heating lines 311 and the heat dissipation portion 32 through the quadrilateral cell with greater density, thereby improving the heat dissipation efficiency of the middle region of the heating element 3, and reducing the risk of excessive concentration of temperature in the middle region of the heating element 3, which leads to local deformation, collapse, and warping of the heating element 3.

[0055] In some embodiments, the heating lines 311 can also be arranged to extend in a curved line form, the heating lines 311 extending in the curved line form have a relatively longer extension path, and the heating area and the heating amount are larger. The adjacent heating lines 311 are combined by the plurality of connecting portions 312 to form a grid region 31 in a grid shape. The heating lines 311 extending in the curved line form can include one or more curved line units.

[0056] Please refer to Figure 1In a specific embodiment, the heat-generating circuit 311 extending in a curved form can include a plurality of "V"-shaped curved units connected head to tail to form the heat-generating circuit 311 extending continuously in a wave shape along the first direction. The connecting portions 312 are symmetrically arranged between the two adjacent heat-generating circuits 311 and connected to the wave crests or wave troughs between the two adjacent heat-generating circuits 311 extending continuously in a wave shape along the second direction. In this way, all the heat-generating circuits 311 of the heat-generating member 3 and all the connecting portions 312 form a grid area 31 with regular hexagonal units. When the hexagonal units are regular hexagons, the grid area 31 formed is a honeycomb grid structure, which has relatively better structural strength and heating uniformity in the plane, further improves the stability and reliability of the heat-generating member 3 abutting against the liquid guide member 2 and the support 4, further improves the heating uniformity of the heat-generating member 3, and reduces the risk of local deformation, collapse, and warping of the heat-generating member 3.

[0057] For reference Figure 2 In a specific embodiment, the heat-generating circuit 311 extending in a curved form can also include a plurality of "U"-shaped curved units connected head to tail to form the heat-generating circuit 311 extending continuously in a wave shape along the first direction. The connecting portions 312 are symmetrically arranged between the two adjacent heat-generating circuits 311 and connected to the wave crests or wave troughs between the two adjacent heat-generating circuits 311 extending continuously in a wave shape along the second direction. In this way, all the heat-generating circuits 311 of the heat-generating member 3 and all the connecting portions 312 form a grid area 31 with regular irregular units. These irregular units have winding curved extension parts, which significantly increase the extension path length of the heat-generating circuit 311 and the surface contact area of the grid area 31 with the liquid guide member 2, and are beneficial to improve the heating power of the heat-generating member 3.

[0058] In other embodiments, the heat-generating circuit 311 extending in a curved form can also include other regular or irregular polygonal units, curved units, or irregular units, which are not limited in the present application and can meet the actual use requirements of the heat-generating member 3.

[0059] In some embodiments, the polygonal units, curved units, or irregular units of the grid area 31 are uniformly arranged on the heat-generating member 3, so that the heating area of the grid area 31 is more uniform, ensuring that the heat-generating member 3 fully and uniformly heats the atomized substrate on the liquid guide member 2, so that the particle size of the generated aerosol particles is more uniform and smaller, and the quality of the aerosol is improved.

[0060] For reference Figure 1In some embodiments, the heating element 3 further comprises two electrode portions 33, which are respectively arranged at two ends of the grid region 31, and the support 4 at least partially abuts on the two electrode portions 33.

[0061] In the present embodiment, the through hole 42 penetrates the support 4 along the Z-axis.

[0062] The grid region 31 in a grid shape is connected between the two electrode portions 33, and the through holes 42 on the support 4 are respectively arranged corresponding to the two electrode portions 33, so that the external power supply can be electrically connected to the grid region 31 in a grid shape through the two through holes 42 and the two electrode portions 33, so that the heating element 3 can drive each heating circuit 311 to work and heat under the driving of electricity, thereby heating and atomizing the atomization substrate transmitted by the liquid guide 2 to the atomization surface 22 and generating aerosol.

[0063] Please refer to Figure 1 In some embodiments, the atomization module 10 further comprises two conductive connecting pieces 5, one end of each of the conductive connecting pieces 5 is electrically connected to the corresponding electrode portion 33 through the corresponding through hole 42, and the other end of each of the conductive connecting pieces 5 is configured to be electrically connected to the corresponding electrode of the external power supply.

[0064] In a specific implementation, the conductive connecting piece 5 comprises a connecting nail head 51 and a connecting nail portion 52, the connecting nail portion 52 is a columnar structure matched with the through hole 42 for plug-in connection, and the length of the connecting nail portion 52 in the Z-axis direction is not less than the depth of the through hole 42 in the Z-axis direction. The connecting nail head 51 is designed as a flat cylindrical structure, coaxially fixedly connected to one end of the connecting nail portion 52, and the diameter of the connecting nail head 51 is greater than the diameter of the connecting nail portion 52.

[0065] When assembled, the conductive connecting piece 5 can be pre-assembled on the support 4, so that the connecting nail portion 52 is respectively plug-in fixed in the corresponding through hole 42, and the connecting nail head 51 is stopped on the side of the support 4 away from the heating element 3. When the support 4 abuts on the periphery of the heating element 3, the end of the connecting nail portion 52 away from the connecting nail head 51 abuts on the corresponding electrode portion 33 of the heating element 3, and the connecting nail head 51 is electrically connected to the corresponding electrode of the external power supply, so as to electrically connect the electrode portion 33 of the heating element 3 to the external power supply through the conductive connecting piece 5.

[0066] In the related design, at least one electrode pin is welded and fixed on each electrode part 33 of the heating element 3, and the heating element 3 is electrically connected to the corresponding electrode of the external power supply through the electrode pins. Since one end of the electrode pin is welded and fixed on the corresponding electrode part 33, the structural complexity, production difficulty and production cost of the heating element 3 are increased to a certain extent, and the automatic assembly of the atomization module 10 is not conducive. The atomization module 10 provided by the present application does not need to weld and fix electrode pins on the two electrode parts 33 of the heating element 3, and the corresponding electrodes of the external power supply can be electrically connected to the corresponding electrode parts 33 of the heating element 3 through the two conductive connecting pieces 5 and the corresponding through holes 42. On the one hand, the structural complexity of the heating element 3 is reduced, and the production difficulty and production cost of the heating element 3 are reduced. On the other hand, the conductive connecting piece 5 can be fixed on the bracket 4 in advance, which significantly improves the convenience of the overall assembly of the atomization module 10, and is conducive to the automatic assembly of the atomization module 10.

[0067] In some embodiments, the bracket 4 is an insulating heat-resistant bracket with a heat-resistant temperature of 180°C or higher.

[0068] The bracket 4 is made of an insulating heat-resistant material to ensure that the bracket 4 can always support and limit the heating element 3 during use and will not deform due to high-temperature baking or direct heating of the heating element 3.

[0069] In a specific embodiment, the bracket 4 is made of an insulating plastic material and is molded. The heat-resistant temperature of the plastic material is 180°C or higher. Compared with the bracket 4 made of ceramic material, the bracket 4 made of plastic material has lower process difficulty, relatively easy shaping, lower material and manufacturing cost, and is conducive to reducing the production cost of the atomization module 10.

[0070] In other embodiments, the bracket 4 can also be made of a ceramic material and sintered. The heat-resistant temperature of the ceramic material is 180°C or higher. Compared with the bracket 4 made of plastic material, the bracket 4 made of ceramic material has higher heat-resistant temperature and better structural strength, can withstand long-time operation of the heating element 3 at higher power, and is conducive to improving the maximum use power and service life of the heating element 3.

[0071] In actual production and manufacturing, appropriate bracket 4 manufacturing materials and manufacturing processes can be selected based on the actual use requirements and cost control of the atomization module 10, which is not limited in the present application, as long as the insulating property and heat-resistant property of the bracket 4 and the support and limiting effect of the bracket 4 on the heating element 3, the liquid guide 2 and the flexible element 1 can be ensured.

[0072] Please refer to Figures 3 to 8In some embodiments of the present application, an atomizer 100 is provided, which comprises a housing 6, and an atomization module 10 as any of the above, which is arranged in the housing 6.

[0073] One end of the housing 6 is provided with an air inlet 621, and the other end is provided with an air outlet 611. The housing 6 is internally provided with a liquid storage cavity 60 for storing an atomization substrate. The housing 6 is arranged along the Z-axis direction, i.e. the direction of gravity. The air inlet 621 is located at the lower end of the housing 6 in the direction of gravity, and the air outlet 611 is located at the upper end of the housing 6 in the direction of gravity.

[0074] The liquid guide 2 is in liquid communication with the liquid storage cavity 60 through the via area, so that the atomization substrate in the liquid storage cavity 60 can flow to the liquid guide 2 through each via 11 in the via area. The heating element 3 is in gas communication with the air inlet 621 and the air outlet 611 through the support 4, so that the air outside the housing 6 can enter the atomization module 10 through the air inlet 621 and carry the generated aerosol out of the air outlet 611.

[0075] The first surface of the flexible member 1 facing away from the liquid guide 2 is arranged towards the air outlet 611, and the side of the heating element 3 facing away from the liquid guide 2 is arranged towards the air inlet 621, so that the atomization module 10 as a whole can be placed horizontally between the air inlet 621 and the air outlet 611 in a plane posture along the X-axis and Y-axis directions, and the atomization surface 22 of the liquid guide 2 is arranged towards the air inlet 621.

[0076] During use, the user sucks the air outlet 611 to generate negative pressure inside the housing 6 of the atomizer 100, and the air outside the housing 6 enters the inside of the housing 6 through the air inlet 621 and flows to the atomization module 10. The atomization substrate in the liquid storage cavity 60 flows to the liquid guide 2 through each via 11 in the via area of the flexible member 1, and is transmitted to the atomization surface 22 by the liquid guide 2, and is then heated, atomized and aerosol is generated by the heating element 3. The generated aerosol is mixed with the incoming external air through the support 4, and is discharged through the air outlet 611 under the action of the airflow, for the user to inhale.

[0077] In the related art, the heating element of the atomization module is wound and accommodated in the liquid guide, and relies on the tension of the heating element itself to adhere to the liquid guide. In order to reduce the resistance, no other supporting structure is provided. The supporting strength of the heating element is low, and the stability and reliability of the adhesion to the liquid guide are poor. After a period of use, the heating element 3 is prone to local deformation, collapse or warping due to alternating cold and hot changes, resulting in insufficient and uneven adhesion of the heating element to the liquid guide, and insufficient and uneven heating of the atomization substrate. Not only does it seriously affect the quality of the generated aerosol, but it also causes the atomization substrate to be over-heated, the atomization substrate to be not fully heated, and the risk of paste core, flying liquid and leakage to be higher. It also increases the resistance due to the paste core problem.

[0078] The atomizer 100 provided in the application places the atomization module 10 horizontally between the air inlet 621 and the air outlet 611 in a plane posture, and presses and combines the heating element 3, the liquid guide 2 and the flexible element 1 through the support 4, thereby improving the support strength of the heating element 3 and the stability and reliability of the plane contact between the heating element 3 and the liquid guide 2, avoiding the problems of local excessive heating of the atomization substrate by the heating element 3 and insufficient heating of the atomization substrate in some areas, significantly reducing the risks of carbon deposition, paste core, flying liquid and liquid leakage, reducing the suction resistance, improving the quality of the aerosol generated by atomization, and improving the user experience.

[0079] Meanwhile, the support 4 presses and combines the heating element 3, the liquid guide 2 and the flexible element 1, thereby significantly improving the structural strength of the heating element 3, which is conducive to reducing the thickness of the heating element 3 and improving the atomization efficiency.

[0080] In addition, the atomization module 10 provided in the application limits the end of the liquid guide 2, the heating element 3 and the support 4 through the flexible element 1. The flexible element 1 itself has a certain elasticity and can deform elastically to a certain extent when subjected to the extrusion force from the support 4, so as to make the heating element 3 abut against the liquid guide 2 to the greatest extent and ensure that the heating element 3 and the liquid guide 2 form good contact during assembly. Moreover, the flexible element 1 can also play a certain degree of buffering and unloading role, thereby significantly reducing the risk of deformation and loosening of the liquid guide 2, the heating element 3 and the support 4 caused by accidental conditions such as bumping and falling during use. In addition, the flexible element 1 can form good sealing with the liquid storage cavity 60 of the atomizer 100 based on its elasticity, thereby further reducing the risk of liquid leakage.

[0081] In the related art, the heating element of the atomization module is wound and arranged in a vertical posture and longitudinally arranged between the air inlet and the air outlet of the atomizer. During use, the air outside the shell directly flows to the atomization module through the air inlet, the aerosol is generated on the side conforming to the airflow direction, and is directly discharged from the air outlet under the driving of the airflow. The spacing between the atomization module and the air outlet is relatively small, the cooling time of the aerosol is relatively short, and the user's mouth is easily scalded due to high temperature of the aerosol.

[0082] The atomizer 100 provided in the application places the atomization module 10 horizontally between the air inlet 621 and the air outlet 611 in a plane posture, and the atomization surface 22 of the liquid guide 2 is arranged towards the air inlet 621. The aerosol is generated at one end towards the air inlet 621 and opposite to the airflow direction, so that the generated aerosol can flow to the air outlet 611 in a detour under the driving of the airflow and be discharged. Compared with the direct discharge mode of the aerosol under the driving of the airflow, the path length of the aerosol flowing in a detour inside the shell 6 is prolonged, which can further reduce the temperature of the aerosol and avoid the problem of scalding of the user's mouth caused by high temperature of the aerosol.

[0083] Please refer to Figure 5 andFigure 7 In some embodiments, the shell 6 is arranged along the Z-axis direction, i.e. the direction of gravity, the air inlet 621 is at the lower end of the shell 6 in the direction of gravity, the air outlet 611 is at the upper end of the shell 6 in the direction of gravity, and the atomization module 10 is arranged close to the air outlet 611. This can increase the distance between the atomization module 10 and the air outlet 611, further lengthen the path length of the aerosol flowing inside the shell 6, and be conducive to reducing the temperature of the aerosol, thereby avoiding the user from being scalded by high-temperature aerosol.

[0084] Please refer to Figures 5 to 8 In some embodiments, the shell 6 is arranged along the Z-axis direction, i.e. the direction of gravity, the air inlet 621 is at the lower end of the shell 6 in the direction of gravity, the air outlet 611 is at the upper end of the shell 6 in the direction of gravity, and the atomization module 10 is arranged close to the air outlet 611. This can increase the distance between the atomization module 10 and the air outlet 611, further lengthen the path length of the aerosol flowing inside the shell 6, and be conducive to reducing the temperature of the aerosol, thereby avoiding the user from being scalded by high-temperature aerosol.

[0085] The seat 7 further comprises an atomization cavity 71, an air outlet hole 72, at least one liquid inlet channel 73, and at least one air outlet channel 74. The atomization cavity 71 is arranged at the lower end of the seat 7 facing the air inlet 621 and is in communication with the air inlet 621. The atomization module 10 is accommodated in the atomization cavity 71.

[0086] The air outlet hole 72 is arranged at the upper end of the seat 7 facing the air outlet 611 and is in communication with the air guide pipe 612.

[0087] The upper end of the liquid inlet channel 73 is in communication with the liquid storage cavity 60, and the lower end of the liquid inlet channel 73 is in communication with the hole region, so that the atomization substrate in the liquid storage cavity 60 flows to the liquid guide 2 through each through hole 11.

[0088] The lower end of the air outlet channel 74 is in communication with the atomization cavity 71, and the upper end of the air outlet channel 74 is in communication with the air outlet hole 72, so that the generated aerosol flows to the air guide pipe 612.

[0089] In use, the atomization substrate in the liquid storage cavity 60 automatically flows to the liquid inlet channel 73 under the action of gravity, and then flows to the liquid inlet surface 21 of the liquid guide 2 through each through hole 11 of the hole region under the transport of the liquid inlet channel 73, and then is transmitted to the atomization surface 22 of the liquid guide 2 by the liquid guide 2; the grid region 31 of the heating element 3 generates heat under the action of electricity to heat and atomize the atomization substrate transmitted to the atomization surface 22 of the liquid guide 2 and generate aerosol, and the generated aerosol is collected in the atomization cavity 71; the airflow entering the atomization cavity 71 through the air inlet 621 drives the generated aerosol to enter the air outlet channel 74, and then flows to the air outlet hole 72 and the air guide pipe 612 under the transport of the air outlet channel 74, and finally is discharged from the air outlet 611 for the user to smoke.

[0090] Please refer to Figures 5 to 6In some embodiments, the first surface of the flexible member 1, which faces away from the liquid guide member 2, abuts against the top surface of the atomization cavity 71 towards the air outlet 611. The upper end of the liquid inlet channel 73 penetrates the upper end surface of the seat body 7 towards the air outlet 611 and communicates with the liquid storage cavity 60, and the lower end of the liquid inlet channel 73 penetrates the top surface of the atomization cavity 71 towards the air outlet 611 and communicates with the via region, so that the atomization substrate in the liquid storage cavity 60 can flow to the liquid guide member 2 through the liquid inlet channel 73 and each via 11 in the via region.

[0091] The flexible member 1 is tightly abutted against the top surface of the atomization cavity 71 under the extrusion of the support 4, and can seal the gap between the top surface of the atomization cavity 71 and the atomization module 10 based on its own elasticity and deformation characteristics, preventing the atomization substrate from leaking from the gap between the top surface of the atomization cavity 71 and the atomization module 10 into the atomization cavity 71, achieving good sealing effect and significantly reducing the risk of liquid leakage.

[0092] Please refer to Figures 4 to 6 In an embodiment, two liquid inlet channels 73 are provided, which are symmetrically distributed. The upper end of each liquid inlet channel 73 penetrates the upper end surface of the seat body 7 towards the air outlet 611 and forms a liquid inlet port 731, and the two liquid inlet ports 731 of the two liquid inlet channels 73 are uniformly distributed around the air outlet hole 72. The lower ends of the two liquid inlet channels 73 converge above the top surface of the atomization cavity 71 to form a liquid inlet cavity 732, and the top surface of the atomization cavity 71 is provided with a liquid outlet port 733 penetratingly, which communicates the liquid inlet cavity 732 with the atomization cavity 71.

[0093] The side of the flexible member 1, which faces away from the liquid guide member 2, is tightly abutted against the top surface of the atomization cavity 71 and closes the liquid outlet port 733, and the via region is within the opening range of the liquid outlet port 733 and makes each via 11 communicate with the liquid outlet port 733.

[0094] In use, the atomization substrate in the liquid storage cavity 60 enters the two liquid inlet channels 73 through the two liquid inlet ports 731 under the action of gravity, and converges in the liquid inlet cavity 732 under the transmission of the two liquid inlet channels 73, and the atomization substrate converged in the liquid inlet cavity 732 flows to the liquid guide member 2 through the liquid outlet port 733 and the via 11, which can avoid the problem of uneven liquid inlet of the liquid guide member 2 caused by the distribution of the liquid inlet channel 73, and ensure the uniformity of the aerosol generated by the heating of the atomization substrate by the heating member 3.

[0095] Please refer to Figures 7 to 8 In an embodiment, two air outlet channels 74 are provided, which are symmetrically distributed, and the two air outlet channels 74 are isolated from and staggered with the two liquid inlet channels 73. The lower end of each air outlet channel 74 extends to the top surface of the atomization cavity 71 and the side wall of the atomization cavity 71, and the upper end of each air outlet channel 74 extends to communicate with the air outlet hole 72.

[0096] The air outlet hole 72 and the two air outlet channels 74 form a three-way structure connecting the air guide pipe 612 and the atomization cavity 71. In use, the aerosol generated in the atomization cavity 71 flows to the two air outlet channels 74, converges in the air outlet hole 72 under the transmission of the two air outlet channels 74, and flows to the air outlet 611 under the transmission of the air outlet hole 72 and the air guide pipe 612, thereby prolonging the path length of the aerosol flowing in the shell 6, and facilitating the cooling of the aerosol.

[0097] Referring to Figures 7 to 8 In some embodiments, the air outlet hole 72 is coaxial with the atomization cavity 71, the aperture of the air outlet hole 72 in the radial direction of the seat body 7 is smaller than the inner cavity size of the atomization cavity 71 in the radial direction of the seat body 7, and the air outlet channel 74 extends obliquely from one side of the atomization cavity 71 to the air outlet hole 72.

[0098] The air outlet channel 74 extends obliquely from one side of the atomization cavity 71 to the air outlet hole 72, and the obliquely extending air outlet channel 74 has a relatively longer extension path, further increasing the path length of the aerosol flowing in the shell 6, and further reducing the temperature of the aerosol. Moreover, the inner wall surface of the obliquely extending air outlet channel 74 can form a certain degree of stop for large droplets in the aerosol, facilitating the attachment of large droplets in the aerosol on the inner wall surface of the obliquely extending air outlet channel 74, preventing large droplets that are not fully atomized from being discharged with the airflow, ensuring the suction taste and quality of the aerosol, and improving the user experience.

[0099] Referring to Figures 4 to 6 In some embodiments, the atomizer 100 further includes a sealing member 8 fixedly clamped between the air guide pipe 612, the shell 6, and the seat body 7 to seal the liquid storage cavity 60 through the sealing member 8, thereby preventing liquid leakage.

In use, the atomization substrate in the liquid storage cavity 60 enters the corresponding liquid inlet channel 73 through the second opening 82, and the aerosol in the air outlet hole 72 enters the air guide pipe 612 under the driving of the airflow through the first opening 81.

[0101] The sealing member 8 is made of a flexible material, which can be selected from a silica gel material, a rubber material, a soft plastic material, etc., and the present application does not limit the same.

[0102] The sealing member 8 can be provided in a cover type structure and detachably sleeved on the upper end of the seat body 7 facing the air outlet 611. After installation, the sealing member 8 is at least partially sealed and clamped between the inner wall of the shell 6 and the outer wall of the seat body 7 and at least partially sealed and clamped between the seat body 7 and the air guide pipe 612 to form an effective seal for the liquid storage cavity 60, preventing the atomized substrate in the liquid storage cavity 60 from leaking out through the gap between the seat body 7 and the inner wall of the shell 6 or the gap between the air guide pipe 612 and the seat body 7, significantly reducing the risk of liquid leakage of the atomizer 100 and improving the user experience.

[0103] Referring to Figure 5 and Figure 7 In some embodiments, the shell 6 includes a shell 61 and a bottom shell 62. One end of the shell 61 is provided with an air outlet 611 communicating with the inner cavity thereof, and the other end of the shell 61 is provided with a mounting opening 613 communicating with the inner cavity thereof.

[0105] The air guide pipe 612 is arranged in the shell 61 in the axial direction, and the air inlet 621 is arranged on the bottom shell 62 and penetrates the bottom shell 62.

[0106] After the bottom shell 62 is fixedly connected to the shell 61 through the mounting opening 613, the bottom shell 62 can cooperate with the air guide pipe 612 to position and fix the seat body 7 in the shell 6, which is simple in structure, has few components and is convenient for combined assembly of the atomizer 100.

[0107] Referring to Figure 6 In some embodiments, the atomization module 10 further includes two conductive connecting members 5. The upper ends of the conductive connecting members 5 are respectively electrically connected to the corresponding electrode portions 33 of the heating element 3 through the corresponding through holes 42 in the bracket 4. The lower ends of the conductive connecting members 5 respectively extend out of the corresponding through holes 42 and are exposed to the bottom surface of the bracket 4 away from the heating element 3.

[0108] The atomizer 100 further includes two power connection terminals 9 fixedly connected to the bottom shell 62. After the bottom shell 62 is fixedly installed on the shell 61, the upper ends of the power connection terminals 9 extend into the atomization cavity 71 and are respectively electrically connected to the corresponding conductive connecting members 5. The lower ends of the power connection terminals 9 are exposed to the bottom shell 62 and are respectively electrically connected to the corresponding electrodes of an external power source, which is convenient for electrical connection of the external power source and the heating element 3 and driving the heating element 3 to work under electrical power, is convenient for combined assembly of the atomizer 100 and is conducive to automatic assembly.

After the bottom shell 62 is assembled on the outer shell 61, the elastic end of the pogo pin connector elastically abuts against the corresponding connecting pin head 51 of the conductive connecting piece, and the fixed end of the pogo pin connector is exposed to the bottom surface of the bottom shell 62 away from the air outlet 611, so as to facilitate electrical connection with the corresponding electrode of the external power supply.

[0110] The pogo pin connector can adapt to different connecting surfaces and slight positional deviations, thereby ensuring that the corresponding electrode of the external power supply can be reliably electrically connected with the corresponding electrode portion 33 on the heating element 3 through the corresponding electrical terminal 9 and the conductive connecting piece 5, and facilitating the assembly of the atomizer 100.

[0111] Please refer to Figure 6 and Figure 8 In some embodiments, the bottom shell 62 further comprises an air inlet pipe portion 622, which is arranged corresponding to the atomization cavity 71 and penetrates through the bottom shell 62 to form an air inlet 621. The air inlet pipe portion 622 is in the form of a boss structure, which defines a receiving groove 623 (as shown in Figure 4 ) between the inner wall of the bottom shell 62 and the air inlet pipe portion 622. The receiving groove 623 is in communication with the atomization cavity 71.

[0112] The air inlet pipe portion 622 is in the form of a boss structure and extends towards the bottom of the atomization cavity 71. During use, the air outside the shell enters the air inlet pipe portion 622 through the air inlet 621 and directly flows to the atomization cavity 71 under the guidance of the air inlet pipe portion 622.

[0113] The atomizer 100 further comprises a liquid absorbing member 20, which is accommodated in the receiving groove 623.

[0114] The atomizer 100 provided in the present application can receive the leaked atomization substrate or the condensate generated by the aerosol in the atomization cavity 71 through the liquid absorbing member 20 and the receiving groove 623, thereby avoiding the direct leakage of the leaked atomization substrate or the condensate generated by the aerosol from the air inlet 621, reducing the risk of liquid leakage of the atomizer 100, and improving the user experience.

The diameter of the air inlet hole 6221 is significantly smaller than the inner diameter of the air inlet pipe portion 622, so as to prevent the leaked atomization substrate or the condensate generated by the aerosol from directly falling into the air inlet pipe portion 622, thereby further reducing the risk of liquid leakage of the atomizer 100.

[0116] In assembly, the conductive connecting piece can be assembled to the support 4 first, and the connecting nail portions 52 are inserted and fixed in the corresponding through holes 42 respectively, and the connecting nail heads 51 are stopped on the bottom surface of the support 4 away from the heating element 3.
