[0038] An aerosol generator is a device that uses heat-not-burning (HNB) technology to heat an aerosol-generating matrix and produce aerosols. Generally, an aerosol generator includes an atomizer, which in turn includes a heating element used to heat the aerosol-generating matrix to produce aerosols. However, atomizers typically contain only one heating element, which can easily result in a low aerosol production rate, failing to meet user needs. To address this issue, please refer to [link to relevant documentation]. Figure 1 This application provides an atomizer 100 and an aerosol generating device 1000.

[0039] Please see Figure 1 The aerosol generating device 1000 of the present application includes an atomizer 100 and an electronic control component 300, wherein the atomizer 100 and the electronic control component 300 are electrically connected.

[0040] It is understood that the atomizer 100 is a structure in the aerosol generating device 1000 capable of heating the aerosol generating matrix to generate aerosols. The aerosol generating matrix is ​​a processed product capable of generating aerosols under heating, ultrasonication, or mechanical vibration. The aerosol generating matrix can be in liquid, fully solid, or semi-solid state. The aerosols can be visible or invisible and may include vapors (e.g., fine particulate matter in a gaseous state, which is typically liquid or solid at room temperature) as well as liquid droplets of gas and condensed vapor.

[0041] The electronic control component 300 is a structure in the aerosol generating device 1000 used to control the operation of the atomizer 100. In some embodiments of this application, the electronic control component 300 includes a power supply and a controller. The power supply provides electrical energy to the atomizer 100. The controller is electrically connected to the power supply and is used to regulate the voltage of the electrical energy. Exemplarily, when the aerosol generating device 1000 is being aspirated, the controller can control the power supply to output electrical energy to the atomizer 100 and regulate the voltage of the output electrical energy so that the adjusted voltage is suitable for the atomizer 100. In this case, the atomizer 100 can heat and atomize the aerosol generating matrix to generate aerosol. When the aerosol generating device 1000 is not being aspirated, the controller can control the power supply to stop providing electrical energy to the atomizer 100. In this case, the atomizer 100 will not heat the aerosol generating matrix. It should be noted that, in some embodiments, the power source can be a dry cell battery or a rechargeable battery, including but not limited to lithium-ion batteries, nickel-metal hydride batteries, and nickel-cadmium batteries.

[0042] Furthermore, in some embodiments, the aerosol generating device 1000 also includes a housing, in which the atomizer 100 and the electronic control assembly 300 are all housed. Specifically, the housing is a structure in the aerosol generating device 1000 that can accommodate and protect the atomizer 100 and other devices. The materials of the housing include, but are not limited to, plastics, aluminum alloys, copper, iron, steel, and carbon fiber composite materials. In one example, the housing may be made of plastic, which makes the housing lighter and facilitates the portability of the aerosol generating device 1000. In another example, the housing may be made of a high-temperature resistant material, which prevents the housing from being damaged by heat (e.g., deformation) and ensures the stability and reliability of the aerosol generating device 1000. High-temperature resistant materials include, but are not limited to, polyetheretherketone (PEEK), high-melting-point metals, and high-temperature ceramics.

[0043] Since the aerosol generating device 1000 in this embodiment includes an atomizer 100, it is understood that the aerosol generating device 1000 has at least the same beneficial effects as the atomizer 100. Therefore, for the beneficial effects of the aerosol generating device 1000, please refer to the beneficial effects of the atomizer 100 described below.

[0044] Please see Figures 1 to 4The atomizer 100 of this application includes an atomizing base 10, a liquid storage component 30, and a heating component 50. The atomizing base 10 includes a first side 11 and a second side 12 facing away from each other; the liquid storage component 30 is connected to the atomizing base 10 and has a liquid storage chamber 31 for storing an aerosol generation matrix, the liquid storage chamber 31 being located on the first side 11; the heating component 50 is disposed on the atomizing base 10 and includes two heating elements 501, each heating element 501 used to heat the aerosol generation matrix to generate aerosol, and includes a heating surface 503. The heating surface 503 of one heating element 501 is parallel to the direction from the first side 11 to the second side 12, and the heating surface 503 of the other heating element 501 is perpendicular to the direction from the first side 11 to the second side 12. It should be noted that, in some embodiments, the heating surface 503 of the other heating element 501 is not only perpendicular to the direction from the first side 11 to the second side 12, but also faces the first side 11.

[0045] It is understood that the atomizer base 10 is a structure in the atomizer 100 used to house components other than the atomizer base 10. Components other than the atomizer base 10, as described herein, include, but are not limited to, the heating element 501. The outer contour shape of the atomizer base 10 may include, but is not limited to, cylinders, cubes, cuboids, triangular prisms, and hexagonal prisms. The material of the atomizer base 10 includes, but is not limited to, plastic, glass, ceramic, and metal.

[0046] The liquid reservoir 30 is a structure in the atomizer 100 used to store the aerosol generation matrix. The liquid reservoir 30 is made of materials including, but not limited to, polyester (PET), polypropylene (PP), ABS plastic, aluminum alloy, or glass. The liquid reservoir 31 can be a regular shape such as a cylinder or cone, or an irregular shape. In this embodiment, the liquid reservoir 30 is also provided with a suction channel 33, which allows aerosol to flow out of the atomizer 100; that is, the user can draw aerosol from the atomizer 100 through the suction channel 33. Furthermore, the liquid reservoir 31 is located on the first side 11, so that the aerosol generation matrix in the liquid reservoir 31 can flow into the atomizing base 10 from the first side 11.

[0047] The heating element 50 is a structure in the atomizer 100 used to heat the aerosol generation matrix. In some embodiments of this application, the heating element 50 includes two heating elements 501, each of which is a device or material capable of generating heat energy and transferring it to the surrounding environment. Of course, in other embodiments, the heating element 50 may also include at least three heating elements 501. For ease of understanding, the following embodiments will use two heating elements 501 as an example.

[0048] For example, the heating element 501 may include porous ceramic, a heating layer, and a conductive element. The heating layer is disposed on one side of the porous ceramic and located on the heating surface 503 of the heating element 501. The conductive element is electrically connected to the heating layer, thereby, when power is supplied to the conductive element, the heating layer can heat and atomize the aerosol-generating matrix in the porous ceramic to generate aerosols on the heating surface 503. It should be noted that, in some embodiments, the porous ceramic is typically prepared by mixing ceramic slurry with a pore-forming agent and then sintering it, resulting in a large number of micropores (not shown in the figure) within the sintered ceramic body. The heating layer includes, but is not limited to, heating circuits, heating elements, heating sheets, heating wires, and heating meshes. The conductive element includes, but is not limited to, electrodes, which may be sheet-like, columnar, or porous powder, etc., without limitation.

[0049] If the heating surface 503 of the heating element 501 faces the second side 12, that is, when the aerosol generating device 1000 is in use, the heating surface 503 of the heating element 501 faces downwards, then the aerosol generated at the heating surface 503 needs to go upwards around the porous ceramic before it can be inhaled by the user. The flow path of the aerosol is relatively complex, resulting in the loss of large-diameter aerosol particles during the flow process, which affects the inhalation taste. In addition, the complex flow path of the aerosol will also cause the temperature of the aerosol to drop. Furthermore, since the characteristic aroma of the aerosol (such as fruity aroma) is easily affected by the temperature of the aerosol, the temperature of the aerosol will also drop, which will also affect the inhalation taste.

[0050] In some embodiments of this application, the heating surface 503 of one heating element 501 is parallel to the direction from the first side 11 to the second side 12, and the heating surface 503 of the other heating element 501 faces the first side 11 and is perpendicular to the direction from the first side 11 to the second side 12. That is, one heating element 501 can perform lateral atomization, and the other heating element 501 can perform upward atomization. As a result, the generated aerosol does not need to bypass the porous ceramic before it can be inhaled by the user, and the flow path of the aerosol is simpler. This reduces the loss of large-particle aerosol and prevents the temperature of the aerosol from dropping, thereby improving the user's inhalation experience. It should be noted that in some embodiments, the direction from the first side 11 to the second side 12 is parallel to the centerline of the suction channel 33.

[0051] In the atomizer 100 of this application embodiment, the atomizer 100 includes a heating component 50, which includes two heating elements 501. The heating elements 501 are used to heat the aerosol generating matrix to generate aerosol. Therefore, compared with the atomizer 100 having only one heating element 501, the amount of aerosol generated is greater, which is beneficial to improving the user's inhalation experience and effectively meeting the user's usage needs.

[0052] In addition, the heating component 50 includes two heating elements 501. Thus, when the atomizer 100 is working, at least one of the two heating elements 501 can be energized to heat the aerosol generating matrix. That is, the two heating elements 501 can heat the aerosol generating matrix by working independently, alternately, or in combination, thereby increasing the number of power levels of the atomizer 100 and effectively meeting the user's needs.

[0053] The atomizer 100 will be further explained below with reference to the accompanying drawings.

[0054] Please see Figures 2 to 4 In some embodiments, the liquid storage tank 31 includes two tanks, which are spaced apart, and two heating elements 501 are used to heat the aerosol generation matrix in the two liquid storage tanks 31 respectively.

[0055] Specifically, in some embodiments, the liquid storage component 30 may have a receiving cavity and a through hole communicating with the receiving cavity. The receiving cavity is used to store the aerosol generation matrix, and the through hole is used to allow the aerosol generation matrix in the receiving cavity to flow out of the receiving cavity. The receiving cavity is provided with a partition that divides the receiving cavity into two non-communicating liquid storage chambers 31, and the through hole is divided into two openings, each of which communicates with one of the two liquid storage chambers 31. In other words, the liquid storage component 30 also has an opening communicating with the liquid storage chamber 31, which allows the aerosol generation matrix in the corresponding liquid storage chamber 31 to flow out to the outside of the liquid storage chamber 31.

[0056] More specifically, in some embodiments, the aerosol generating matrix stored in the two reservoirs 31 may have the same flavor. In this case, when the two heating elements 501 heat the aerosol generating matrix in the two reservoirs 31 respectively, more aerosol is generated compared to when the atomizer 100 includes only one heating element 501, which helps to improve the user's inhalation experience and effectively meet the user's usage needs.

[0057] In other embodiments, the aerosol generating matrix stored in the two liquid storage chambers 31 may have different flavors. In this case, when the two heating elements 501 heat the aerosol generating matrix in the two liquid storage chambers 31 respectively, the generated aerosols can mix flavors, thereby improving the richness of flavors, effectively meeting the user's sucking taste and usage needs, and enhancing product competitiveness.

[0058] Please see Figure 2 and Figure 4 In some embodiments, the atomizing seat 10 is provided with an atomizing channel 13 and a liquid guiding channel 14.

[0059] Specifically, in some embodiments, the heating surface 503 is opposite to the atomizing channel 13, and at least a portion of the heating element 501 is disposed within the liquid guiding channel 14, which is used to supply the aerosol generating matrix in the liquid storage tank 31 to the heating element 501. In the aerosol generating device 1000 ( Figure 1 When the liquid is drawn in, the aerosol generating matrix in the storage chamber 31 can flow to the heating element 501 through the liquid guiding channel 14. In this case, the heating element 501 can heat and atomize the aerosol generating matrix and generate aerosol in the atomization channel 13.

[0060] Furthermore, please combine Figure 4 In some embodiments, the atomizing channel 13 includes two atomizing channels, and the atomizing base 10 is also provided with two air inlets 15. The two air inlets 15 are respectively connected to the two atomizing channels 13 and are used to allow outside air to flow into the corresponding atomizing channel 13. The cross-sectional dimensions of the two air inlets 15 are the same. This ensures that the amount of outside air flowing into the two atomizing channels 13 is the same, so that the amount of aerosol generated by the two heating elements 501 heating the aerosol generating matrix is ​​approximately the same, thereby ensuring the uniformity of aerosol mixing and improving the user's inhalation experience.

[0061] Please see Figure 2 , Figure 4 , Figure 5 and Figure 6 In some embodiments, both the atomizing channel 13 and the liquid guiding channel 14 include two atomizing channels 13 and two liquid guiding channels 14. The two atomizing channels 13 include a first atomizing channel 131 and a second atomizing channel 133, and the two liquid guiding channels 14 include a first liquid guiding channel 141 and a second liquid guiding channel 143. The two heating elements 501 include a first heating element 51 and a second heating element 53. The first heating element 51 includes a first heating surface 511, which is parallel to the direction from the first side 11 to the second side 12 and is opposite to the first atomizing channel 131. The first heating element 51 is disposed in the first liquid guiding channel 141. The second heating element 53 includes a second heating surface 531, which is perpendicular to the direction from the first side 11 to the second side 12 and is opposite to the second atomizing channel 133. The second heating element 53 is disposed in the second liquid guiding channel 143.

[0062] Specifically, in some embodiments, at least a portion of the first heating element 51 is disposed within the first liquid guiding channel 141, and the first liquid guiding channel 141 is used to allow the aerosol generating matrix in a liquid storage tank 31 to flow to the first heating element 51, thereby enabling the first heating element 51 to heat and atomize the aerosol generating matrix to generate aerosol in the first atomization channel 131; at least a portion of the second heating element 53 is disposed within the second liquid guiding channel 143, and the second liquid guiding channel 143 is used to allow the aerosol generating matrix in another liquid storage tank 31 to flow to the second heating element 53, thereby enabling the second heating element 53 to heat and atomize the aerosol generating matrix to generate aerosol in the second atomization channel 133. It should be noted that the suction channel 33 is connected to both the first atomization channel 131 and the second atomization channel 133, thus allowing the aerosol in both the first atomization channel 131 and the second atomization channel 133 to be drawn in by the user through the suction channel 33.

[0063] Please combine Figure 4 In some embodiments, the first heating element 51 further includes a first liquid guiding surface 513 opposite to the first heating surface 511, and the inner wall of the first liquid guiding channel 141 is provided with an abutment surface that abuts against the first liquid guiding surface 513. The abutment surface facilitates the installation and positioning of the first heating element 51 in the first liquid guiding channel 141, thereby improving the assembly efficiency of the first heating element 51. Furthermore, it increases the contact area between the first heating element 51 and the inner wall of the first liquid guiding channel 141. That is, in addition to the peripheral wall of the first heating element 51 (connecting the first heating surface 511 and the first liquid guiding surface 513) abutting against the inner wall (side wall) of the first liquid guiding channel 141, the first liquid guiding surface 513 also abuts against the inner wall (abutment surface) of the first liquid guiding channel 141, thereby improving the sealing performance between the first heating element 51 and the inner wall of the first liquid guiding channel 141.

[0064] Furthermore, in some embodiments, a first sealing element 61 is provided between the contact surface and the first liquid guiding surface 513. The first sealing element 61 is used to seal the gap between the contact surface and the first liquid guiding surface 513. The provision of the first sealing element 61 can further improve the sealing performance between the inner wall of the first heating element 51 and the first liquid guiding channel 141, preventing the aerosol generating matrix from leaking into the first atomization channel 131 through the gap between the inner wall of the first heating element 51 and the first liquid guiding channel 141. This reduces waste of the aerosol generating matrix and prevents it from entering the first atomization channel 131 and clogging the air inlet 15 connected to the first atomization channel 131, thereby improving the stability and reliability of the aerosol generating device 1000. It should be noted that in some embodiments, the first sealing element 61 can be made of materials such as rubber, silicone, plastic, or synthetic fibers. Rubber materials include, but are not limited to, natural rubber, nitrile rubber, fluororubber, polyurethane rubber, EPDM rubber, or silicone rubber.

[0065] Please combine Figure 6 In some embodiments, the second heating element 53 further includes a second liquid guiding surface 533 and a peripheral side surface 535. The second liquid guiding surface 533 is opposite to the second heating surface 531, and the peripheral side surface 535 is connected between the second heating surface 531 and the second liquid guiding surface 533. A second sealing member 63 is provided between the peripheral side surface 535 and the inner wall of the second liquid guiding channel 143, and the second sealing member 63 is used to seal the gap between the peripheral side surface 535 and the inner wall of the second liquid guiding channel 143.

[0066] The second sealing element 63 improves the sealing between the inner walls of the second heating element 53 and the second liquid guiding channel 143, preventing the aerosol generating matrix from leaking into the second atomizing channel 133 through the gap between the inner walls of the second heating element 53 and the second liquid guiding channel 143. This reduces waste of the aerosol generating matrix and prevents it from entering the second atomizing channel 133 and clogging the air inlet 15 connected to the second atomizing channel 133, thus improving the stability and reliability of the aerosol generating device 1000. It should be noted that in some embodiments, the second sealing element 63 may be made of materials such as rubber, silicone, plastic, or synthetic fibers. Rubber materials include, but are not limited to, natural rubber, nitrile rubber, fluororubber, polyurethane rubber, EPDM rubber, or silicone rubber.

[0067] Please see Figures 2 to 4In some embodiments, the atomizing base 10 includes a base 16, a first liquid guiding member 17, and a second liquid guiding member 18. The base 16 is connected to the liquid storage member 30; the first liquid guiding member 17 is disposed on the side of the base 16 facing the liquid storage chamber 31 and has a first liquid guiding channel 141; the second liquid guiding member 18 is disposed on the side of the base 16 facing the liquid storage chamber 31 and has a second liquid guiding channel 143 and a first sub-channel 1331. The second liquid guiding member 18 and the first liquid guiding member 17 together form the first atomizing channel 131, and together with the base 16, form the second sub-channel 1333. The first sub-channel 1331 and the second sub-channel 1333 are connected to form the second atomizing channel 133.

[0068] Specifically, in some embodiments, the first atomizing channel 131 includes a gap between the first liquid guiding element 17 and the second liquid guiding element 18, and one end of the first atomizing channel 131 is connected to the air inlet 15 ( Figure 4 The air inlet 15 on the left side is connected to the air outlet 15, and the other end is connected to the suction channel 33. When the aerosol generating device 1000 is being suctioned, outside air flows into the first atomizing channel 131 through the air inlet 15, so that the first heating element 51 can generate aerosol when heating the aerosol generating matrix, and the aerosol generated in the first atomizing channel 131 can be suctioned by the user through the suction channel 33 (e.g., Figure 4 (As shown by the dashed arrow on the left). The second liquid guide 18 faces the base 16, and / or, the base 16 has a groove on the side facing the second liquid guide 18, and this groove is the second sub-channel 1333. One end of the first sub-channel 1331 communicates with the suction channel 33, the other end of the first sub-channel 1331 communicates with one end of the second sub-channel 1333, and the other end of the second sub-channel 1333 communicates with the air inlet 15 (…). Figure 4 The air inlet 15 on the right side is connected, so that when the aerosol generating device 1000 is being drawn in, outside air can flow into the second sub-channel 1333 through the air inlet 15, and then into the first sub-channel 1331 through the second sub-channel 1333, so that when the second heating element 53 heats the aerosol generating matrix, it can generate aerosol, and the aerosol generated in the second atomization channel 133 can be drawn in by the user through the suction channel 33 (e.g., Figure 4 (As shown by the dashed arrow on the right). It should be noted that in some embodiments, the second atomizing channel 133 can be roughly in the form of a semi-closed U-shaped structure, and the second heating surface 531 is opposite to the first sub-channel 1331.

[0069] Further, please refer to Figure 2 , Figure 4 and Figure 6In some embodiments, the second liquid guiding member 18 includes a first sub-member 181 and a second sub-member 183. The first sub-member 181 is disposed on the base 16 and has a portion of a first sub-path 1431 and a first sub-channel 1331, which together with the base 16 form a second sub-channel 1333. The second sub-member 183 is connected to the side of the first sub-member 181 away from the base 16 and has another portion of the second sub-path 1433 and the first sub-channel 1331. The first sub-path 1431 and the second sub-path 1433 communicate with each other and together form a second liquid guiding channel 143.

[0070] Specifically, in some embodiments, the first sub-component 181 includes a first sidewall and a second sidewall facing away from each other. The first sidewall is opposite to the base 16. The second sub-channel 1333 can be a groove provided on the first sidewall, and the first sub-path 1431 can be a groove provided on the second sidewall. Wherein, when the second heating element 53 is disposed in the second liquid guiding component 18, the second liquid guiding surface 533 is opposite to the first sub-path 1431.

[0071] In some embodiments, the first sub-component 181 and the second sub-component 183 are an integral structure, that is, the first sub-component 181 and the second sub-component 183 are integrally molded into a single structure. This can improve the structural strength of the second liquid guiding component 18 and prevent the first sub-component 181 and the second sub-component 183 from separating during the use of the aerosol generating device 1000, thereby improving the stability and reliability of the aerosol generating device 1000. In other embodiments, the first sub-component 181 and the second sub-component 183 are separate structures, that is, the first sub-component 181 and the second sub-component 183 are two different structures. The first sub-component 181 and the second sub-component 183 can be combined by a detachable connection method or a non-detachable connection method. The detachable connection method includes, but is not limited to, snap-fit ​​connection and bolt connection; the non-detachable connection method includes, but is not limited to, bonding or welding.

[0072] Please see Figure 2 and Figure 6In some embodiments, a third sealing element 65 is provided between the first sub-component 181 and the second sub-component 183. The third sealing element 65 is used to seal the gap between the first sub-component 181 and the second sub-component 183. This prevents leakage of the second liquid guiding channel 143 through the gap between the first sub-component 181 and the second sub-component 183, thereby reducing waste of the aerosol generation matrix. It also prevents leakage of the second atomizing channel 133 through the gap between the first sub-component 181 and the second sub-component 183, thereby preventing aerosol leakage from the second atomizing channel 133 and ensuring the user's inhalation experience. It should be noted that in some embodiments, the third sealing element 65 may be made of materials such as rubber, silicone, plastic, or synthetic fibers. Among these, rubber materials include, but are not limited to, natural rubber, nitrile rubber, fluororubber, polyurethane rubber, EPDM rubber, or silicone rubber.

[0073] In some embodiments of this application, the third seal 65 and the second seal 63 are an integral structure, that is, the third seal 65 and the second seal 63 are an integral structure made by integral molding, which can reduce the number of parts of the atomizer 100, facilitate the installation of the third seal 65 and the second seal 63, and help improve the assembly efficiency of the atomizer 100.

[0074] Please see Figure 2 , Figure 3 , Figure 4 and Figure 7 In some embodiments, the first liquid guiding member 17 is provided with a first ventilation channel 171, which is connected to both the outside air and the first liquid guiding channel 141, so as to allow outside air to flow into the liquid storage tank 31 through the first liquid guiding channel 141. Specifically, in some embodiments, the first ventilation channel 171 may be provided on the outer side of the peripheral wall of the first liquid guiding member 17, and one end of the first ventilation channel 171 is connected to the air inlet 15 (the air inlet 15 connected to the first atomizing channel 131), and the other end of the first ventilation channel 171 is connected to the first liquid guiding channel 141.

[0075] Among them, in the aerosol generating device 1000 ( Figure 1When the aerosol generating device 1000 is aspirated, the aerosol generating matrix in the storage chamber 31 (which is connected to the first liquid guiding channel 141) can be consumed, causing a negative pressure to form in the storage chamber 31. In this case, if the storage chamber 31 is not connected to the outside air, the aerosol generating matrix in the storage chamber 31 will have difficulty entering the first liquid guiding channel 141 quickly, or even be unable to enter the first liquid guiding channel 141, thereby affecting the amount of aerosol generated and worsening the user's suction experience. In this application, the first ventilation channel 171 is connected to both the outside air and the first liquid guiding channel 141 to allow outside air to flow into the storage chamber 31 through the first liquid guiding channel 141. Therefore, when the aerosol generating device 1000 is aspirated, the first ventilation channel 171 can regulate the air pressure in the storage chamber 31, thereby ensuring that the aerosol generating matrix in the storage chamber 31 can flow into the first liquid guiding channel 141, thus ensuring the amount of aerosol generated and improving the user's suction experience.

[0076] Please see Figure 2 , Figure 3 , Figure 6 and Figure 8 In some embodiments, the second liquid guiding member 18 is provided with a second ventilation channel 185, which is connected to both the outside air and the second liquid guiding channel 143, so as to allow outside air to flow into the liquid storage tank 31 through the second liquid guiding channel 143. Specifically, in some embodiments, the second ventilation channel 185 may be provided on the outer side of the peripheral wall of the second liquid guiding member 18, and one end of the second ventilation channel 185 is connected to the air inlet 15 (the air inlet 15 connected to the second atomizing channel 133), and the other end of the second ventilation channel 185 is connected to the second liquid guiding channel 143.

[0077] Among them, in the aerosol generating device 1000 ( Figure 1 When the aerosol generating device 1000 is aspirated, the aerosol generating matrix in the storage chamber 31 (which is connected to the second liquid guiding channel 143) can be consumed, causing a negative pressure to form in the storage chamber 31. In this case, if the storage chamber 31 is not connected to the outside air, the aerosol generating matrix in the storage chamber 31 will have difficulty entering the second liquid guiding channel 143 quickly, or even be unable to enter the second liquid guiding channel 143, thereby affecting the amount of aerosol generated and worsening the user's suction experience. In this application, the second ventilation channel 185 is connected to both the outside air and the second liquid guiding channel 143 to allow outside air to flow into the storage chamber 31 through the second liquid guiding channel 143. Thus, when the aerosol generating device 1000 is aspirated, the second ventilation channel 185 can regulate the air pressure in the storage chamber 31, thereby ensuring that the aerosol generating matrix in the storage chamber 31 can flow into the second liquid guiding channel 143, thus ensuring the amount of aerosol generated and improving the user's suction experience.

[0078] Please see Figures 2 to 4 In some embodiments, the atomizing base 10 further includes a top cover 19, which is connected to the base 16, the first liquid guide 17 and / or the second liquid guide 18. The top cover 19 is provided with a first through hole 191 and a second through hole 193. The first through hole 191 is used to connect the first liquid guide channel 141 and a liquid storage tank 31, and the second through hole 193 is used to connect the second liquid guide channel 143 and another liquid storage tank 31.

[0079] Specifically, please combine Figure 1 In some embodiments, in the direction from the first side 11 to the second side 12, the first liquid guiding element 17 and the second liquid guiding element 18 are disposed between the top cover 19 and the base 16. Exemplarily, the top cover 19 may be connected to the base 16, the first liquid guiding element 17, and the second liquid guiding element 18, and the second liquid guiding element 18 may be connected to the base 16, thereby forming a single integral structure (i.e., the atomizing seat 10) from the top cover 19, the base 16, the first liquid guiding element 17, and the second liquid guiding element 18. When the aerosol generating device 1000 is aspirated, the aerosol generating matrix in one storage chamber 31 can flow into the first liquid guiding channel 141 through the first perforation 191; the aerosol generating matrix in the other storage chamber 31 can flow into the second liquid guiding channel 143 through the second perforation 193, thereby enabling the atomizer 100 to generate aerosol for the user to inhale.

[0080] Furthermore, in some embodiments, a fourth sealing element 67 is provided between the top cover 19 and the first liquid guiding element 17. The fourth sealing element 67 surrounds the first through hole 191 and is used to seal the gap between the top cover 19 and the first liquid guiding element 17. The fourth sealing element 67 prevents leakage of the aerosol generating matrix through the gap between the top cover 19 and the first liquid guiding element 17, thereby reducing waste of the aerosol generating matrix and lowering the possibility of damage to the electronic control component 300 due to contact between the aerosol generating matrix and the electronic control component 300, thus improving the stability and reliability of the aerosol generating device 1000. It should be noted that in some embodiments, the fourth sealing element 67 may be made of materials such as rubber, silicone, plastic, or synthetic fibers.

[0081] In some embodiments, a fifth sealing element 69 is provided between the top cover 19 and the second liquid guiding element 18. The fifth sealing element 69 surrounds the second through hole 193 and is used to seal the gap between the top cover 19 and the second liquid guiding element 18. The fifth sealing element 69 prevents leakage of the aerosol generating matrix through the gap between the top cover 19 and the second liquid guiding element 18, thereby reducing waste of the aerosol generating matrix and lowering the possibility of damage to the electronic control component 300 due to contact between the aerosol generating matrix and the electronic control component 300, thus improving the stability and reliability of the aerosol generating device 1000. It should be noted that in some embodiments, the fifth sealing element 69 may be made of materials such as rubber, silicone, plastic, or synthetic fibers.

[0082] In some embodiments of this application, the fourth seal 67 and the fifth seal 69 may be an integral structure, that is, the fourth seal 67 and the fifth seal 69 are an integral structure made by integral molding, which can reduce the number of parts of the atomizer 100, facilitate the installation of the fourth seal 67 and the fifth seal 69, and help improve the assembly efficiency of the atomizer 100.

[0083] Please see Figures 1 to 4 In some embodiments, the atomizer 100 further includes a barrier 70 that covers the opening. The atomizing seat 10 is installed on the side of the barrier 70 away from the liquid storage chamber 31 and connected to the liquid storage chamber 30. The barrier 70 has at least two through holes 71, which are respectively connected to the two liquid storage chambers 31. The through holes 71 are used to allow the aerosol generating matrix in the corresponding liquid storage chamber 31 to flow into the atomizing seat 10. The barrier 70 can seal the gap between the liquid storage chamber 30 and the atomizing seat 10, preventing the aerosol generating matrix in the liquid storage chamber 31 from leaking through the gap. This not only reduces the waste of aerosol generating matrix but also reduces the possibility of the aerosol generating matrix coming into contact with the electronic control component 300 and causing damage to the electronic control component 300. On the other hand, it can isolate the two liquid storage chambers 31, ensuring that the two liquid storage chambers 31 are not connected to each other.

[0084] Specifically, in some embodiments, when the aerosol generating device 1000 is aspirated, the aerosol generating matrix in one storage tank 31 can flow into the first liquid guiding channel 141 sequentially through the through hole 71 and the first perforation 191; the aerosol generating matrix in the other storage tank 31 can flow into the second liquid guiding channel 143 sequentially through the through hole 71 and the second perforation 193, thereby enabling the atomizer 100 to generate aerosol for the user to inhale. It should be noted that in some embodiments, the barrier 70 can be made of materials such as rubber, silicone, plastic, or synthetic fibers. Among these, rubber materials include, but are not limited to, natural rubber, nitrile rubber, fluororubber, polyurethane rubber, EPDM rubber, or silicone rubber.
