Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to atomizers and electronic atomization devices. Background Technology

[0002] Aerosols are colloidal dispersion systems formed by the dispersion and suspension of solid or liquid particles in a gaseous medium. Because aerosols can be absorbed by the human body through the respiratory system, they provide users with a novel alternative absorption method. For example, electronic atomization devices that generate aerosols by heating liquid or solid aerosol-generating matrices are applied in various fields to deliver inhalable aerosols to users, replacing conventional product forms and absorption methods.

[0003] Generally, electronic atomizing devices atomize an aerosol-generating matrix, which is a matrix material that can produce aerosols after atomization. Traditional electronic atomizing devices with a multi-core, multi-chamber structure usually have multiple cartridges, resulting in insufficient flavor mixing, poor reproduction, and a lack of flavor complexity. Summary of the Invention

[0004] Therefore, it is necessary to provide an atomizer and electronic atomization device to address the problem of insufficient flavor mixing when using multi-core, multi-chamber setups in traditional electronic atomization devices.

[0005] An atomizer, comprising:

[0006] The base has a central axis;

[0007] Multiple atomizing components are disposed on the base. Each atomizing component has an atomizing surface. Each atomizing component heats and atomizes the atomized aerosol to generate an aerosol matrix through its own atomizing surface. The multiple atomizing surfaces of the multiple atomizing components are all facing the central axis and are spaced apart from each other around the central axis.

[0008] Multiple conductive elements are provided, and each of the atomizing surfaces is provided with a heating film and an electrode that are electrically connected to each other. A conductive element is provided between each pair of adjacent atomizing components, and the opposite ends of the conductive element abut against two adjacent electrodes on the two adjacent atomizing surfaces, respectively.

[0009] The atomizing components and the conductive elements together form an atomizing cavity, and at least a portion of the conductive elements are used for an external power supply assembly.

[0010] In the aforementioned atomizer, the two opposite ends of the conductive element are respectively abutted against two adjacent electrodes on two adjacent atomizing surfaces. Multiple atomizing components and multiple conductive elements are arranged alternately around the central axis. The multiple atomizing components are electrically connected through the multiple conductive elements. At least some of the multiple conductive elements are used to connect to an external power supply component. In this way, the multiple electrically connected atomizing components can be connected to the power supply component through at least some of the conductive elements, thereby realizing the power supply to the multiple atomizing components.

[0011] Furthermore, multiple atomizing components and multiple conductive elements enclose an atomizing chamber, which is circumferentially sealed by the staggered atomizing components and conductive elements. Simultaneously, the atomizing surfaces of the atomizing components facing the central axis confront the atomizing chamber. The aerosols generated by the multiple atomizing components during operation all enter the same atomizing chamber, where they are thoroughly mixed before flowing out for the user to inhale. The various flavor aerosols generated by the multiple atomizing components are thoroughly mixed, resulting in excellent flavor reproduction and a layered taste. Additionally, by electrically connecting multiple atomizing components together through multiple conductive elements to form only one atomizing chamber, multiple cartridges are eliminated, resulting in a more compact overall structure and a smaller atomizer size, making it easy to carry and use.

[0012] In some embodiments, the number of atomizing components and the number of conductive elements are both even numbers. The even number of atomizing components are arranged in pairs around the central axis, and the even number of conductive elements and the even number of atomizing components are staggered and abutted against each other around the central axis to form the atomizing cavity.

[0013] In some embodiments, each electrode on the atomizing surface includes a first electrode and a second electrode, and the heating film on each atomizing surface is connected between the first electrode and the second electrode on the atomizing surface;

[0014] The number of atomizing components and conductive elements are both two. The two atomizing surfaces of the two atomizing components are arranged at intervals relative to each other. One of the two conductive elements abuts between the two first electrodes on one side of the two atomizing surfaces, and the other of the two conductive elements abuts between the two second electrodes on the other side of the two atomizing surfaces.

[0015] In some embodiments, the base has a plurality of air inlets, each of which corresponds to a plurality of atomizing surfaces. Each air inlet connects the atomizing chamber to the outside, and each air inlet has an outer side wall away from the central axis. The two adjacent ends of each outer side wall and its corresponding atomizing surface are flush with each other.

[0016] In some embodiments, the atomizer further includes a housing, the base is disposed within the housing, the housing has an air outlet channel communicating with the atomizing chamber, and the atomizing surface is parallel to the axial direction of the air outlet channel.

[0017] In some embodiments, the number of atomizing components is even, and the even number of atomizing components are arranged in pairs around the central axis with intervals between them. The distance between the two atomizing surfaces of the two atomizing components in each pair of oppositely arranged atomizing components is the same as the diameter of the air outlet channel.

[0018] In some embodiments, the housing has multiple independent liquid storage chambers, the base includes a first seat and multiple second seats, each of the second seats and the first seat are engaged with each other radially intersecting the direction of the central axis, and each atomizing component is assembled between a second seat and the first seat.

[0019] Each of the second housings has a liquid inlet channel, and the multiple atomizing components are connected to the multiple liquid storage chambers through the liquid inlet channels on their respective second housings.

[0020] In some embodiments, the first base includes a first base body and a plurality of mounting posts protruding from the first base body, the plurality of mounting posts being spaced apart from each other around the central axis, and each mounting post having a conductive element disposed on its inner side facing the central axis;

[0021] Each of the second housings engages with two adjacent mounting posts among the plurality of mounting posts, the atomizing component having the atomizing surface on one side abutting against two conductive elements on the two adjacent mounting posts, and the atomizing component having the side opposite to the atomizing surface abutting against the second housing.

[0022] In some embodiments, the atomizing surface protrudes from the inner surface of the second base facing the mounting post, a first gap is formed between the mounting post and the inner surface of the second base, a second gap is formed between the conductive element and the inner surface of the second base, the first gap and the second gap communicate to form an air passage gap, the air passage gap is located on the side of the atomizing cavity opposite to the air outlet channel and communicates with the outside.

[0023] Each of the second seats has an air exchange groove on its outer surface facing away from the mounting post. The air exchange groove on each of the second seats is connected to the liquid inlet channel on the second seat and the air passage defined by the second seat.

[0024] An electronic atomizing device includes a power supply assembly and the aforementioned atomizer, wherein the power supply assembly is used to supply power to the atomizer. Attached Figure Description

[0039] See Figures 1-2 , Figure 1 This is a cross-sectional schematic diagram of the atomizer 100 in some embodiments of this application. Figure 2 This is an exploded view of the atomizer 100 in some embodiments of this application. This application provides an atomizer 100, including a base 10, multiple atomizing components 30, and multiple conductive elements 50. The base 10 has a central axis, and the multiple atomizing components 30 are disposed on the base 10. Each atomizing component 30 has an atomizing surface 31, which is used to heat the aerosol-generating matrix adsorbed within the atomizing component 30 to atomize and form an aerosol. That is, each atomizing component 30 heats and atomizes the aerosol-generating matrix through its own atomizing surface 31 to generate an aerosol.

[0040] Multiple atomizing surfaces 31 of multiple atomizing components 30 all face the central axis and are spaced apart around the central axis. Each atomizing surface 31 is provided with a heating film and an electrode that are electrically connected to each other. A conductive element 50 is provided between each pair of adjacent atomizing components 30, and the opposite ends of the conductive element 50 abut against two adjacent electrodes on the two adjacent atomizing surfaces 31, respectively. Multiple atomizing components 30 and multiple conductive elements 50 are arranged alternately around the central axis, and the multiple atomizing components 30 are electrically connected through the multiple conductive elements 50. At least some of the multiple conductive elements 50 are used to connect to an external power supply component 201. In this way, the multiple electrically connected atomizing components 30 can be connected to the power supply component 201 through at least some of the conductive elements 50, so as to realize the power supply to the multiple atomizing components 30. The power supply component 201 includes a battery for supplying power to the multiple atomizing components 30.

[0041] Optionally, at least some of the conductive elements 50 extend out of the base 10 and can directly contact the power supply assembly 201 to supply power. The electrical connection method is simple and reliable. For example, the conductive element 50 is a metal plate, one end of which abuts against two adjacent atomizing surfaces 31, and the other end of which is exposed relative to the base 10 and can contact and conduct with the power supply assembly 201. Specifically, the conductive element 50 can be set as an L-shaped metal plate with a large bottom area, which can reliably and effectively contact and conduct with the power supply assembly 201 through the large bottom area. Alternatively, at least some of the conductive elements 50 can achieve electrical connection and conduction with the power supply assembly 201 through an intermediate component. The intermediate component can be an electrical connection structure such as a conductive terminal. This is equivalent to the conductive element 50 being located inside the base 10 and conducting with the conductive terminal, with the conductive terminal exposed relative to the base 10 to contact and conduct with the power supply assembly 201.

[0042] Furthermore, multiple atomizing components 30 and multiple conductive elements 50 enclose an atomizing chamber 60, which is circumferentially sealed by the staggered contact of the atomizing components 30 and conductive elements 50. Simultaneously, the atomizing surfaces 31 of the atomizing components 30 facing the central axis confront the atomizing chamber 60. The aerosols generated by the multiple atomizing components 30 during operation all enter the same atomizing chamber 60, where they are thoroughly mixed before flowing out for the user to inhale. The various flavor aerosols formed by the multiple atomizing components 30 are thoroughly mixed, resulting in excellent flavor reproduction and a layered taste. Additionally, by electrically connecting and assembling multiple atomizing components 30 together via multiple conductive elements 50, only one atomizing chamber 60 is formed, eliminating the need for multiple cartridges. This results in a more compact overall structure, a smaller atomizer 100, and easier portability and use.

[0043] According to some embodiments of this application, the atomizing component 30 includes an atomizing element 32, which can be a porous structure or a straight-hole structure, capable of absorbing and storing the aerosol generation matrix. For example, the atomizing element 32 is ceramic or a glass component with straight holes.

[0044] The atomizing assembly 30 also includes a sealing element 34. The atomizing element 32 has an atomizing surface 31. One end of the atomizing element 32 facing away from the atomizing surface 31 is fitted into the sealing element 34 to seal the atomizing element 32 and prevent leakage of the aerosol generation matrix stored in the atomizing element 32. One end of the atomizing element 32 with the atomizing surface 31 is exposed relative to the sealing element 34 and faces the atomizing cavity 60. A heating film and an electrode electrically connected to each other are disposed on the atomizing surface 31. When the heating film is energized, it heats the aerosol generation matrix stored in the atomizing element 32 and atomizes it to form an aerosol flowing into the atomizing cavity 60. Optionally, the thickness of the atomizing element 32 in the direction perpendicular to the atomizing surface 31 is 0.5mm-0.7mm.

[0045] According to some embodiments of this application, the number of atomizing components 30 and the number of conductive elements 50 are both even numbers. An even number of atomizing components 30 are arranged in pairs, spaced apart from each other, around a central axis. An even number of conductive elements 50 and an even number of atomizing components 30 are staggered and abutted against each other around the central axis, forming an atomizing cavity 60. In this way, by setting an even number of atomizing components 30 and arranging them in pairs, the atomizing surfaces 31 of two opposing atomizing components 30 face each other. The large aerosol particles formed on the two atomizing surfaces 31 can mix with each other, facilitating the thorough mixing of aerosols of various flavors formed by atomization.

[0046] For example, there are four atomizing components 30 and four conductive elements 50. The four atomizing components 30 and four conductive elements 50 are staggered around the central axis. Two pairs of atomizing components 30 are arranged relatively spaced apart, and the four conductive elements 50 connect the two pairs of atomizing components 30 together to connect and energize the power supply component 201. In this case, the four conductive elements 50 also form two relatively spaced pairs. One pair of the two pairs of conductive elements 50 is connected to the positive second electrode of the power supply component 201. In this way, two of the four atomizing components 30 and the remaining two atomizing components 30 can be connected in parallel to realize the power supply of each atomizing component 30.

[0047] For example, there are two atomizing components 30 and two conductive elements 50. The two atomizing components 30 are arranged at intervals relative to each other, and the two conductive elements 50 and the two atomizing components 30 are staggered and abutted around the central axis. The two conductive elements 50 electrically connect the two atomizing components 30 together to connect and energize the power supply component 201. Specifically, the two conductive elements 50 connect the two atomizing components 30 in parallel, and the two conductive elements 50 extend out of the base 10 to contact the power supply component 201. In this way, when the two conductive elements 50 contact the power supply component 201, power can be supplied to the two parallel atomizing components 30.

[0048] Understandably, in some other embodiments, the number of atomizing components 30 and conductive elements 50 is odd, for example, three in each case. The three atomizing components 30 and the three conductive elements 50 are staggered around the central axis. Two of the three conductive elements 50 extend out of the base 10 and can contact the power supply component 201 to conduct electricity. In this way, two of the three atomizing components 30 and the remaining one atomizing component 30 are connected in parallel to achieve electrical connection and power conduction of the three atomizing components 30. At the same time, the three atomizing surfaces 31 of the three atomizing components 30 all face the central axis and the atomizing cavity 60, which can fully mix the different flavored aerosols atomized on each atomizing surface 31 within the same atomizing cavity 60.

[0049] According to some embodiments of this application, the electrodes on the atomizing surface 31 of each atomizing component 30 include a first electrode and a second electrode, and the heating film on each atomizing surface 31 is connected between the first electrode and the second electrode on the atomizing surface 31 so that the heating film is connected to the circuit for power supply through the first electrode and the second electrode.

[0050] Furthermore, when multiple atomizing components 30 are electrically connected through multiple conductive elements 50, the conductive elements 50 connect adjacent first electrodes and second electrodes of two adjacent atomizing components 30 to connect the two adjacent atomizing components 30 in series, or the conductive elements 50 connect two adjacent first electrodes or two adjacent second electrodes of two adjacent atomizing components 30 to connect the adjacent atomizing components 30 in parallel.

[0051] In some specific embodiments, there are two atomizing components 30 and two conductive elements 50. The two atomizing surfaces 31 of the two atomizing components 30 are arranged at a distance from each other. One of the two conductive elements 50 abuts between two first electrodes on one side of the two atomizing surfaces 31, and the other of the two conductive elements 50 abuts between two second electrodes on the other side of the two atomizing surfaces 31. That is, one conductive element 50 connects the first electrodes of the two atomizing components 30, and the other conductive element 50 connects the second electrodes of the two atomizing components 30, thus connecting the two atomizing components 30 in parallel through the two conductive elements 50. Subsequently, the two conductive elements 50 are connected to the power supply component 201 to supply power to the two atomizing components 30.

[0052] According to some embodiments of this application, the base 10 is provided with a plurality of air inlets 11, each corresponding to a plurality of atomizing surfaces 31, and each air inlet 11 connects the atomizing chamber 60 to the outside. In this way, an air inlet 11 is provided on the base 10 for each atomizing surface 31. After passing through the air inlet 11, the external airflow flows to the atomizing surface 31 corresponding to the air inlet 11. This allows the external airflow to flow through the plurality of air inlets 11 and through the plurality of corresponding atomizing surfaces 31, which can carry and mix the aerosol formed at each atomizing surface 31, and prevent the air inlet 11 from deviating from a certain atomizing surface 31, thus affecting the aerosol carrying and mixing effect.

[0053] Furthermore, each air inlet 11 has an outer wall 112 away from the central axis, and the two adjacent ends of each outer wall 112 and its corresponding atomizing surface 31 are flush with each other. That is, part of the sidewall of the air inlet 11 is close to the central axis, and another part of the sidewall of the air inlet 11 is away from the central axis and close to the outer periphery of the base 10. The part of the sidewall away from the central axis is defined as the outer wall 112 of the air inlet 11. The external airflow flows along the air inlet 11 to the atomizing surface 31 corresponding to the air inlet 11, carrying aerosol. By setting the two adjacent ends of the outer wall 112 of each air inlet 11 and its corresponding atomizing surface 31 to be flush with each other, there is no step between the outer wall 112 and the atomizing surface 31. The external airflow can flow smoothly along the air inlet 11 to the corresponding atomizing surface 31, and the airflow path is smooth.

[0054] Understandably, in the axial direction of the air inlet 11, the outer sidewall 112 of the air inlet 11 includes a first sidewall 113 and a second sidewall 115. The first sidewall 113 is located between the atomizing surface 31 and the second sidewall 115. The first sidewall 113 is flush with the atomizing surface 31. The second sidewall 115 can be inclined outward relative to the first sidewall 113, or the second sidewall 115 can be flush with the first sidewall 113. The arrangement of the second sidewall 115 is not limited here.

[0055] Furthermore, the air inlet 11 extends longitudinally along its own axis, and the extension of the air inlet 11 to a certain length can guide and enhance the airflow gathering effect.

[0056] According to some embodiments of this application, the atomizer 100 further includes a housing 70, with a base 10 disposed within the housing 70. The housing 70 has an air outlet channel 71 communicating with the atomizing chamber 60. Thus, external airflow, carrying the atomized aerosol through the atomizing chamber 60, flows out through the air outlet channel 71 communicating with the atomizing chamber 60 for the user to inhale. Furthermore, the atomizing surface 31 is parallel to the axial direction of the air outlet channel 71, with the atomizing surface 31 of the atomizing component 30 arranged laterally, and there is no tilt angle between the atomizing surface 31 and the axial direction of the air outlet channel 71. This facilitates the smooth flow of the aerosol generated on the atomizing surface 31 to the air outlet channel 71 by the airflow, improving the aerosol outflow rate.

[0057] Furthermore, the number of atomizing components 30 is even, and the even number of atomizing components 30 are arranged in pairs around the central axis. With an even number of atomizing components 30 arranged in pairs and spaced apart, the atomizing surfaces 31 of the two opposing atomizing components 30 face each other. The large aerosol particles formed on the two atomizing surfaces 31 can face each other and mix, which facilitates the full mixing of aerosols of various flavors formed by atomization.

[0058] Furthermore, the distance between the two atomizing surfaces 31 of each pair of oppositely arranged atomizing components 30 is the same as the diameter of the air outlet channel 71, which is equivalent to setting several pairs of atomizing components 30. The atomizing surfaces 31 of each pair of atomizing components 30 are arranged relatively at intervals, and the distance between the two atomizing surfaces 31 of each pair of atomizing components 30 is the same as the diameter of the air outlet channel 71. In this way, the width of the atomizing chamber 60 is consistent with the diameter of the air outlet channel 71.

[0059] If the distance between the two atomizing surfaces 31 is too far, the volume of the atomizing chamber 60 increases, and the gas velocity at the atomizing surface 31 decreases, which is not conducive to carrying large droplets. If the distance between the two atomizing surfaces 31 is too close, the increase in airflow velocity in the atomizing chamber 60 does not significantly improve droplet carrying capacity. On the contrary, the narrow width of the atomizing chamber 60 increases the risk of droplets hitting the inner wall of the atomizing chamber 60, which is not conducive to droplets flowing out of the atomizing chamber 60. Therefore, making the width of the atomizing chamber 60 the same as the diameter of the air outlet channel 71 can improve the carrying rate of large droplets and improve the vaping experience. Optionally, the distance between the two atomizing surfaces 31 in each pair of atomizing components 30 is 3mm-4mm.

[0060] In addition, an air outlet 13 is provided on the side of the base 10 near the air outlet channel 71. The air outlet 13 connects the atomizing chamber 60 and the air outlet channel 71. The diameter of the air outlet 13, the diameter of the air outlet channel 71, and the spacing between the two atomizing surfaces 31 of each pair of atomizing components 30 are the same. There are no steps between the atomizing surface 31, the air outlet 13, and the air outlet channel 71. The airflow at the atomizing surface 31 can smoothly flow through the air outlet 13 to the air outlet channel 71, improving the smoothness of airflow.

[0061] See Figure 1 and Figure 6 According to some embodiments of this application, a plurality of independent liquid storage chambers 77 are formed within the outer casing 70 to store aerosol generating matrices of different flavors through the plurality of independent liquid storage chambers 77. Further, the outer casing 70 includes a shell 72, a central tube 74 and a partition 76. The central tube 74 is disposed within the shell 72 and has an air outlet channel 71. The partition 76 is disposed between the central tube 74 and the shell 72 to divide the space between the shell 72 and the central tube 74 into a plurality of independent liquid storage chambers 77.

[0062] See Figures 2-4The base 10 includes a first seat 12 and a plurality of second seats 14. Each second seat 14 and the first seat 12 are engaged with each other radially intersecting the central axis. Each atomizing component 30 is assembled between the second seat 14 and the first seat 12. Thus, the atomizing component 30 is fixed within the base 10 by the cooperation of the first seat 12 and the second seat 14. Furthermore, each atomizing component 30 is mounted via a second seat 14, and the installation and removal of the atomizing component 30 only requires radial installation or removal of the second seat 14.

[0063] Furthermore, each second base 14 is provided with a liquid inlet channel 15, and the atomizing component 30 is connected to a liquid storage chamber 77 through the liquid inlet channel 15 on the second base 14 to which it is assembled. In other words, each liquid storage chamber 77 is fluidly connected to an atomizing component 30 through a liquid inlet channel 15, supplying liquid to that atomizing component 30. For multiple atomizing components 30, each atomizing component 30 is connected to multiple liquid storage chambers 77 through its corresponding second base 14's liquid inlet channel 15, and the multiple liquid storage chambers 77 supply liquid to the multiple atomizing components 30 through the multiple liquid inlet channels 15 on the multiple second bases 14. Thus, different aerosol generating matrices within the multiple liquid storage chambers 77 can flow to different atomizing components 30 through different liquid inlet channels 15, supplying liquid to multiple different atomizing components 30.

[0064] Understandably, the liquid inlet channel 15 is formed by opening a through hole in the second seat 14, or by opening a groove with a notch in the second seat 14. The second seat 14 and the outer shell 70 together enclose the liquid inlet channel 15. The method of forming the liquid inlet channel 15 is not limited here.

[0065] Optionally, the inner wall of the liquid inlet channel 15 is provided with a liquid inlet 151 communicating with the atomizing component 30, and multiple guide grooves 153 extending along the extension direction of the liquid inlet channel 15, so as to guide the aerosol generation matrix in the liquid inlet channel 15 to flow more smoothly to the liquid inlet 151 through the multiple guide grooves 153, so as to facilitate liquid supply.

[0066] Specifically, the first seat 12 has an air inlet 11 at the end away from the liquid storage chamber 77, and a plurality of second seats 14 are arranged around the first seat 12 and enclosed to form an air outlet 13. External airflow flows through the air inlet 11 on the first seat 12 to the atomizing chamber 60, and finally flows through the air outlet 13 formed by the enclosed space between the plurality of second seats 14 to the air outlet channel 7171.

[0067] The first base 12 includes a first base body 121121 and a plurality of mounting posts 123 protruding from the first base body 121121. The plurality of mounting posts 123 are spaced apart from each other around a central axis. Each mounting post 123 has a conductive element 50 disposed on its inner side facing the central axis, so that the plurality of conductive elements 50 can be mounted through the plurality of mounting posts 123 on the first base body 121121. Each second base 14 is engaged with two adjacent mounting posts 123. The side of the atomizing component 30 with the atomizing surface 31 abuts against two conductive elements 50 on the two adjacent mounting posts 123, and the side of the atomizing component 30 facing away from the atomizing surface 31 abuts against the second base 14. In this way, the atomizing component 30 is installed between the first base 12 and the second base 14, and the atomizing surface 31 of the atomizing component 30 contacts the two adjacent conductive elements 50, thereby realizing the electrical connection between the plurality of atomizing components 30.

[0068] Each second seat 14 has an air exchange groove 16 on its outer surface 143 facing away from the mounting column 123. The air exchange groove 16 on each second seat 14 is connected to the liquid inlet channel 15 on the second seat 14 and the outside, so as to keep the air pressure in the liquid storage chamber 77 connected to the liquid inlet channel 15 balanced with the outside air pressure, and prevent the internal pressure from decreasing after the aerosol matrix in the liquid storage chamber 77 gradually enters the liquid, thus affecting the smoothness of liquid inlet.

[0069] See Figures 3-5 Specifically, the atomizing surface 31 protrudes from the inner surface 141 of the second seat 14 facing the mounting post 123. That is, when the atomizing component 30 is fitted inside the second seat 14, the atomizing surface 31 of the atomizing component 30 protrudes from the inner surface 141 of the second seat 14. After the second seat 14 and the first seat 12 are subsequently engaged radially, the conductive element 50 on the mounting post 123 abuts against the atomizing surface 31 protruding from the inner surface 141 of the second seat 14. Thus, a first gap is formed between the mounting post 123 and the inner surface 141 of the second seat 14, and a second gap is formed between the conductive element 50 and the inner surface 141 of the second seat 14. The first gap and the second gap communicate to form an air passage gap 20. The air passage gap 20 is located on the side of the atomizing chamber 60 facing away from the air outlet channel 7171 and communicates with the outside. That is, the side of the outside airflow flowing into the atomizing chamber 60 communicates with the air passage gap 20, thereby making the air passage gap 20 communicate with the outside.

[0070] Furthermore, the ventilation groove 16 on each second seat 14 connects the liquid inlet channel 15 on the second seat 14 and the air passage 20 defined by the second seat 14. This is equivalent to having a ventilation groove 16 on the outer surface 143 of the second seat 14 connecting the liquid inlet channel 15, and the ventilation groove 16 extending to the position of the air passage 20 defined by the second seat 14, thereby connecting the liquid inlet channel 15 and the air passage 20 on the second seat 14. This ensures that the liquid storage chamber 77 connected to the liquid inlet channel 15 maintains pressure balance with the outside environment, ensuring smooth liquid intake. Specifically, one end of the ventilation groove 16 is connected to the liquid inlet channel 15, and the other end of the ventilation groove 16 is connected to the first gap, thus connecting the liquid storage chamber 77 and the air passage 20.

[0071] According to some embodiments of this application, this application also provides an electronic atomizing device 200, including a power supply component 201 and an atomizer 100 as described in any of the above embodiments. The power supply component 201 supplies power to the atomizer 100. The atomizer 100 has multiple atomizing surfaces 31, and the multiple atomizing surfaces 31 face the same atomizing cavity 60, which can fully mix the aerosols formed by atomization at the multiple atomizing surfaces 31 within the same atomizing cavity 60, improving the thoroughness of mixing multiple aerosols and enhancing the layering of the inhalation flavor. Furthermore, the atomizer 100 internally integrates multiple atomizing components 30 and multiple conductive components 50 in an alternating manner around a central axis, resulting in a simple overall structure that eliminates the need for multiple cartridges. The atomizer 100 is small in size and easy to carry and use.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
