[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese Invention Patent Application No. CN202411578583.6, filed on November 6, 2024, entitled "An Atomizer and Atomizing Device", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of atomization technology, specifically to an atomizer and atomization device. Background Technology

[0004] Atomizing devices, as products used for atomization, consist of a power supply and an atomizer. The power supply provides electrical energy to the atomizer and controls its operation, while the atomizer heats and atomizes the substance to be atomized. Different substances have different flavors, and traditional atomizing devices that only offer a single flavor can no longer meet user needs. Therefore, atomizing devices need to store multiple flavors of substances to provide users with a variety of vaping options. However, currently, atomizing devices that can provide multiple flavors are generally composed of two or more stacked e-liquid tank components, resulting in a complex structure, complicated assembly process, and high cost.

[0040] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods.

This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0041] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0042] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0043] One embodiment of this application provides an atomizer, which is part of an atomizing device and is used to heat and atomize a stored liquid to be atomized, so that the liquid liquid to be atomized becomes a state that can be inhaled by the user, for example, turning the liquid liquid to be atomized into an aerosol.

[0044] Please refer to Figures 1-11. The atomizer provided in this application includes: a liquid storage chamber 10, a first sealing cap 20, a second sealing cap 30, a first atomizing core 40, and a second atomizing core 50.

[0045] The liquid storage tank 10 has an opening 11 and a bottom 12, with an air inlet 13 on the bottom 12. The liquid storage tank 10 is similar to a cylindrical structure, with the opening 11 of the liquid storage tank 10 corresponding to the opening of the cylindrical structure and the bottom 12 of the liquid storage tank 10 corresponding to the bottom of the cylindrical structure.

[0046] The first sealing cover 20 is fixed inside the liquid storage chamber 10, and the liquid storage chamber 10 is axially divided into a first liquid storage chamber and a second liquid storage chamber. The first liquid storage chamber is located on the side near the bottom 12 of the chamber, and the second liquid storage chamber is located on the side near the opening 11 of the chamber. A first vent hole 21 is opened on the first sealing cover 20.

[0047] The second sealing cover 30 is fixed to the opening 11. The second sealing cover 30 has a second vent hole 31, which is also the air outlet of the atomizer.

[0048] The first atomizing core 40 is disposed in the first liquid storage chamber. The two ends of the first atomizing core 40 are connected to the air inlet 13 and the first vent 21, respectively. The first atomizing core 40 is used to heat and atomize the liquid to be atomized stored in the first liquid storage chamber.

[0049] The second atomizing core 50 is disposed in the second liquid storage chamber. The two ends of the second atomizing core 50 are respectively connected to the first vent 21 and the second vent 31. The second atomizing core 50 is used to heat and atomize the liquid to be atomized stored in the second liquid storage chamber.

[0050] The first atomizing core 40 includes a first lead 44, and the second atomizing core 50 includes a second lead 54. The first lead 44 and the second lead 54 are located on the same side of the air intake 13.

[0051] Using the atomizer in the above embodiment, by fixing a first sealing cap 20 inside the liquid storage chamber 10, the space inside the liquid storage chamber 10 is axially divided into a first liquid storage chamber and a second liquid storage chamber. A second sealing cap 30 is fixed at the opening 11, so that the liquid storage chamber 10 and the first sealing cap 20 enclose a relatively sealed first liquid storage chamber, and the liquid storage chamber 10, the first sealing cap 20, and the second sealing cap 30 enclose a relatively sealed second liquid storage chamber. Different flavored liquids can be stored in the first and second liquid storage chambers. Combined with the first atomizing core 40 in the first liquid storage chamber and the second atomizing core 50 in the second liquid storage chamber, the corresponding flavored liquid can be heated and atomized as needed. When switching to heat different flavored liquids, only the corresponding atomizing core needs to be switched, eliminating the need for other switching structures. This effectively simplifies the structure of a multi-flavor atomizer, thereby simplifying the atomizer assembly process and reducing the manufacturing cost. Correspondingly, it also simplifies the assembly process of atomizing devices containing atomizers and reduces the manufacturing cost of atomizing devices. The first lead wire 44 and the second lead wire 54 are located on the same side of the air inlet 13, which facilitates assembly and simplifies the atomizer structure.

[0052] In some embodiments, referring to Figures 1-2, the first liquid storage chamber is formed by the side wall of the liquid storage tank 10, the bottom 12 of the liquid storage tank 10, and the first sealing cap 20. The second liquid storage chamber is formed by the side wall of the liquid storage tank 10, the first sealing cap 20, and the second sealing cap 30. The air inlet 13, the first atomizing core 40, the first vent 21, the second atomizing core 50, and the second vent 31 are sequentially connected to form a complete airflow channel. The first and second liquid storage chambers share a single liquid storage tank 10. When using the atomizer to inhale different flavors of liquids, the external airflow can share a single airflow channel. This eliminates the need for multiple liquid storage tanks 10 and multiple airflow channels based on the variety of liquid flavors, and also eliminates the need for corresponding switching structures, such as a rotating structure, to align the liquid storage chamber and mouthpiece corresponding to the desired flavor of liquid. The atomizer designed in this application effectively simplifies the structural design, material costs, and assembly costs.

[0053] To ensure a good seal and ease of installation, the first sealing cap 20 and the second sealing cap 30 can be made of elastic plastic or rubber, such as silicone. The first sealing cap 20 not only separates the liquid storage chambers but also separates the liquid to be atomized in the first and second liquid storage chambers, preventing cross-contamination of flavors and better ensuring the user's inhalation experience when using the atomizer or atomizing device containing an atomizer.

[0054] Please refer to Figures 1-2. The atomizer also includes a first liquid reservoir 60 and a second liquid reservoir 70. The first liquid reservoir 60 is disposed within a first liquid reservoir chamber, and a first atomization channel 61 is formed within the first liquid reservoir 60. The two ends of the first atomization channel 61 are respectively connected to the air inlet 13 and the first vent 21. The first atomizing core 40 is disposed within the first atomization channel 61. The second liquid reservoir 70 is disposed within a second liquid reservoir chamber, and a second atomization channel 71 is formed within the second liquid reservoir 70. The two ends of the second atomization channel 71 are respectively connected to the first vent 21 and the second vent 31. The second atomizing core 50 is disposed within the second atomization channel 71.

[0055] The first liquid storage component 60 is used to absorb and store the liquid to be atomized in the first liquid storage chamber, and the second liquid storage component 70 is used to absorb and store the liquid to be atomized in the second liquid storage chamber. For example, both the first liquid storage component 60 and the second liquid storage component 70 are liquid storage cotton, which absorbs and stores the liquid to be atomized through the porous structure on the liquid storage cotton.

[0056] When the length of the liquid storage cotton in the liquid storage chamber 10 of the atomizer is too long, the liquid to be atomized will accumulate at the bottom of the liquid storage cotton due to gravity, that is, at the end of the liquid storage cotton near the bottom 12 of the chamber. After the liquid accumulates, leakage is likely to occur.

[0057] Correspondingly, this application uses the first sealing cap 20 to axially divide the liquid storage chamber 10 into a first liquid storage cavity and a second liquid storage cavity. The first and second liquid storage cavities are shorter in length relative to the axial direction of the liquid storage chamber 10. For example, the length of the first liquid storage cavity is approximately half the length of the liquid storage chamber 10, and the length of the second liquid storage cavity is also approximately half the length of the liquid storage chamber 10. Correspondingly, the length of the first liquid storage component 60 or liquid storage cotton in the first liquid storage cavity is shortened, and the length of the second liquid storage component 70 or liquid storage cotton in the second liquid storage cavity is shortened, reducing the risk of leakage caused by the accumulation of atomized liquid at the bottom of the liquid storage cotton when the length of the liquid storage cotton is too long. It should be noted that the lengths mentioned refer to the length along the axial direction of the liquid storage chamber 10.

[0058] The length ratio of the first and second liquid storage chambers relative to the liquid storage tank 10 can be set according to actual conditions. For example, if the user prefers the flavor of the liquid to be atomized in the second liquid storage chamber, the length of the second liquid storage chamber can be set to be larger. This application does not impose specific limitations on the lengths of the first and second liquid storage chambers; they can be set according to actual conditions.

[0059] In addition to designs containing two flavors of liquid to be atomized, the atomizer designed in this application can also include three or four flavors of liquid to be atomized. For example, if the atomizer contains three flavors of liquid to be atomized, the number of first sealing caps 20 is increased, dividing the liquid storage chamber 10 axially into three liquid storage cavities, and storing different flavors of liquid to be atomized in the three liquid storage cavities, while simultaneously setting three corresponding atomizing coils. In other embodiments, the atomizer designed in this application can also include one flavor of liquid to be atomized, that is, storing the same flavor of liquid to be atomized in the first liquid storage cavity and the second liquid storage cavity. In this case, the length of the liquid storage element or liquid storage cotton in the liquid storage chamber 10 is effectively shortened by the first sealing cap 20, thereby avoiding leakage problems caused by excessive length of the liquid storage element or liquid storage cotton.

[0060] Please refer to Figures 1-2. In this embodiment, the atomizer further includes an adapter tube 80, the first atomizing core 40 includes a first atomizing tube 41, and the second atomizing core 50 includes a second atomizing tube 51. The two ends of the adapter tube 80 are respectively sleeved onto the first atomizing tube 41 and the second atomizing tube 51. Taking the connection between the adapter tube 80 and the first atomizing tube 41 as an example, the adapter tube 80 can be sleeved onto the outside of the first atomizing tube 41, or the adapter tube 80 can be sleeved onto the inside of the first atomizing tube 41. The connection between the adapter tube 80 and the second atomizing tube 51 is similar and will not be described further here.

[0061] To facilitate the fixing of the adapter tube 80, the side wall of the adapter tube 80 abuts against the first vent hole 21. To ensure the sealing of the first vent hole 21, multiple sealing protrusions are provided on the side wall of the first vent hole 21. The sealing protrusions abut against the side wall of the adapter tube 80 to ensure the sealing of the connection between the adapter tube 80 and the first vent hole 21. The adapter tube 80 allows for the indirect connection of the first atomizing tube 41 and the second atomizing tube 51, facilitating the assembly of the atomizer. At the same time, it also facilitates the connection between the first atomizing tube 41 and the second atomizing tube 51, meaning that the first atomizing tube 41 and the second atomizing tube 51 can be connected through the space inside the adapter tube 80.

[0062] In other embodiments, the adapter tube 80 may not be required, and the first atomizing tube 41 and the second atomizing tube 51 may be an integral structure, or the first atomizing tube 41 and the second atomizing tube 51 may be two independent parts that abut against each other.

[0063] Please refer to Figure 5. In some embodiments of this application, the first atomizing core 40 further includes a first liquid guiding element 42 and a first heating element 43. The first liquid guiding element 42 is annular columnar, and its outer wall is fixed to the inner wall of the first atomizing tube 41. The first heating element 43 is fixed to the inner wall of the first liquid guiding element 42. The two ends of the internal channel of the first liquid guiding element 42 are respectively connected to the channel of the first atomizing tube 41 near the air inlet 13 and the channel of the first atomizing tube 41 near the adapter pipe 80. The second atomizing core 50 further includes a second liquid guiding element 52 and a second heating element 53. The second liquid guiding element 52 is also annular columnar, and its outer wall is fixed to the inner wall of the second atomizing tube 51. The second heating element 53 is fixed to the inner wall of the second liquid guiding element 52. The two ends of the internal channel of the second liquid guiding element 52 are respectively connected to the channel of the second atomizing tube 51 near the adapter pipe 80 and the channel of the second atomizing tube 51 near the second vent 31.

[0064] The first liquid guiding element 42 and the second liquid guiding element 52 are used to absorb and transfer the liquid to be atomized. For example, both the first liquid guiding element 42 and the second liquid guiding element 52 are made of liquid guiding cotton or porous ceramic. Taking the first liquid guiding element 42 as an example, corresponding liquid guiding holes are opened on the first atomizing tube 41 so that the adjacent first liquid storage element 60 and the first liquid guiding element 42 can contact each other. The first liquid guiding element 42 in contact with the first liquid storage element 60 can absorb the liquid to be atomized on the first liquid storage element 60 and transfer the absorbed liquid to be atomized to the inner wall of the first liquid guiding element 42. Similarly, corresponding liquid guiding holes are also opened on the second atomizing tube 51 so that the adjacent second liquid storage element 70 and the second liquid guiding element 52 can contact each other. The first heating element 43 is used to heat and atomize the liquid to be atomized on the inner wall of the first liquid guiding element 42 and turn the liquid to be atomized on the first liquid guiding element 42 into an inhalable aerosol. The second heating element 53 is used to heat and atomize the liquid to be atomized on the inner wall of the second liquid guiding element 52, and to turn the liquid to be atomized on the second liquid guiding element 52 into an inhalable aerosol. The first heating element 43 and the second heating element 53 can be mesh, filament, or sheet-like resistive structures, and this application does not impose specific limitations.

[0065] Please refer to Figures 5-9. The two ends of the adapter tube 80 are respectively fitted into the first atomizing tube 41 and the second atomizing tube 51. A lead wire position 81 is provided on the outer wall of the adapter tube 80, and the lead wire position 81 and part of the second lead wire 54 are inserted into it.

[0066] The lead wire position 81 is, for example, a groove or hole opened on the outer wall of the adapter tube 80. The lead wire position 81 can fix part of the second lead wire 54, avoiding problems such as poor contact and deformation of the second heating element 53 caused by the second lead wire 54 shaking due to heat. The setting of the lead wire position 81 better ensures the working state of the second atomizing core 50.

[0067] Referring to Figure 9, the side wall of the adapter tube 80 is provided with a protrusion 82, the two ends of which abut against the first atomizing tube 41 and the second atomizing tube 51, respectively. In some embodiments, the protrusion 82 can be a ring structure or a block structure. When the protrusion 82 is a block structure, multiple protrusions 82 can be provided. On the one hand, they can abut against the first atomizing tube 41 and the second atomizing tube 51 on both sides to provide a limiting function; on the other hand, multiple protrusions 82 can provide sufficient support for the first atomizing tube 41 and the second atomizing tube 51. To facilitate the connection between the adapter tube 80 and the first atomizing tube 41 and the second atomizing tube 51, guide surfaces are provided at both ends of the adapter tube 80, such as conical annular surfaces.

[0068] Referring to Figure 9, multiple lead positions 81 are provided on the outer wall of the adapter tube 80, and the multiple lead positions 81 are spaced apart around the axis of the adapter tube 80. In some embodiments, the lead positions 81 are, for example, lead grooves. With multiple circumferentially spaced lead positions 81, the alignment of the second lead 54 with the lead position 81 does not need to be considered; that is, the second lead 54 can be inserted through any one of the lead positions 81, facilitating atomizer assembly. In some embodiments, the multiple lead positions 81 are equally spaced around the axis of the adapter tube 80.

[0069] Please refer to Figures 5-6 and 8. A notch 411 is provided at the end of the first atomizing tube 41 facing the second atomizing tube 51. A portion of the second lead 54 extends beyond the notch 411 and is positioned on the outer wall of the first atomizing tube 41. The notch 411 serves two purposes: firstly, it positions and limits the assembly of the second lead 54; secondly, it places the second lead 54 outside the first atomizing tube 41, preventing it from passing through the first liquid guide 42. Based on the function or purpose of the notch 411, in other embodiments, the notch 411 can be replaced with a perforated structure.

[0070] Please refer to Figures 5-8. In this embodiment, a portion of the first lead 44 is placed on the outer wall of the first atomizing tube 41. The first lead 44 and the second lead 54 placed on the outer wall of the first atomizing tube 41 converge, so that the first lead 44 and the second lead 54 are distributed on the same side of the first atomizing tube 41. In this way, the distribution of the first lead 44 and the second lead 54 can be relatively concentrated, which is convenient for assembly. At the same time, the concentrated distribution of the leads facilitates fixing the leads (the abbreviations for the first lead 44 and the second lead 54) and makes it easier to shorten the length of the leads. When the lead length is shortened, it is also beneficial to reduce the line resistance, thereby reducing energy loss and improving the energy utilization rate of the atomizer and the atomizing device containing the atomizer.

[0071] In some embodiments, a lead wire hole 15 is provided on the bottom 12 of the storage tank, through which the first lead wire 44 and the second lead wire 54, after converging, pass out of the storage tank 10. In some embodiments, a slot or fence-like structure can also be provided on the bottom 12 of the storage tank, and the lead wire hole 15 is placed in the slot or fence-like structure, so as to guide and protect the lead wire structure passing out of the lead wire hole 15.

[0072] Two lead holes 15 are provided on the bottom of the chamber 12. The first lead 44 and the second lead 54 are each configured as two separate wires. Both the first lead 44 and the second lead 54 have positive and negative leads. The positive leads of the first lead 44 and the second lead 54 exit through the same lead hole 15, and the negative leads of the first lead 44 and the second lead 54 also exit through the same lead hole 15, but the positive and negative leads exit through different lead holes 15. Separating the leads corresponding to the positive and negative leads through the two lead holes 15 prevents eddy currents caused by different leads crossing within the same lead hole 15, which could lead to localized overheating and affect the normal operation of the atomizer coil. Furthermore, the classification of leads through the two lead holes 15 simplifies the atomizer manufacturing and assembly process; for example, assembly workers can simply thread the leads through the corresponding lead holes 15.

[0073] Three blind wiring holes 16 are provided at the end of the chamber bottom 12 opposite to the chamber opening 11, and each blind wiring hole 16 contains an electrode. Each electrode in each blind wiring hole 16 is electrically connected to at least one lead, which refers to either the first lead 44 or the second lead 54. For example, the positive pin of the first lead 44 and the positive pin of the second lead 54 are electrically connected to the electrode in the same blind wiring hole 16, while the negative pins of the first lead 44 and the second lead 54 are electrically connected to electrodes in different blind wiring holes 16. Alternatively, the negative pins of the first lead 44 and the second lead 54 are electrically connected to the electrode in the same blind wiring hole 16, while the positive pins of the first lead 44 and the second lead 54 are electrically connected to electrodes in different blind wiring holes 16. After the electrodes in the blind wiring holes 16 are connected to the corresponding lead pins, the connection can be checked using a fixture. If the assembly is satisfactory, the atomizer can be assembled; if the assembly is unsatisfactory, it can be corrected promptly. If the pins of the leads are directly soldered to the control board, problems such as cold solder joints and false solder joints are likely to occur. Since the connection between the pins and the control board is a one-time soldering, problems cannot be inspected or modified, resulting in higher production costs.

[0074] By sharing a positive or negative electrode, the first lead 44 and the second lead 54 connect the first atomizing coil 40 and the second atomizing coil 50 in parallel, effectively simplifying the atomizer structure and reducing manufacturing and assembly difficulties. The parallel connection of the first atomizing coil 40 and the second atomizing coil 50 provides more operating modes, such as only the first atomizing coil 40 working, only the second atomizing coil 50 working, or both working simultaneously, offering users a richer flavor experience.

[0075] Referring to Figure 5, in some embodiments, the first lead wire 44 is provided with a first bend 441 and a second bend 442 along the axial direction. The first bend 441 is located at the end of the first liquid guide 42 away from the opening 11, and the second bend 442 is located at the end of the first atomizing tube 41 away from the opening 11. The second lead wire 54 is provided with a third bend 541, which is located at the end of the second liquid guide 52 away from the opening 11, and is situated between the second liquid guide 52 and the adapter tube 80.

[0076] The first bend 441, the second bend 442, and the third bend 541 are all right-angle bends. The first bend 441 ensures a closer fit for the first lead 44 when it switches from the inner wall of the first liquid guide 42 to the inner wall of the first atomizing tube 41. Similarly, the second bend 442 ensures a closer fit for the first lead 44 when it exits from the inner wall of the first atomizing tube 41. The third bend 541 ensures a closer fit for the second lead 54 when it switches from the inner wall of the second liquid guide 52 to the outer side of the first atomizing tube 41. These pre-designed bends allow for a more compact and neat assembly of multiple leads within the atomizer, reducing the impact on the airflow channel.

[0077] Please refer to Figure 10. The first sealing cover 20 has a liquid injection blind hole 24. The first sealing cover 20 has a liquid injection blind hole 24 on the side facing the opening 11.

[0078] Please refer to Figure 2. A support ring 14 is provided at the bottom 12 of the liquid storage chamber 10, corresponding to the position of the air inlet 13. During atomizer assembly, the first atomizing core 40 and the second atomizing core 50 are pre-connected via an adapter 80. The end of the first atomizing tube 41 furthest from the adapter 80 is sleeved and fixed to the support ring 14. The first liquid storage component 60 is installed in the first liquid storage chamber, followed by the first sealing cap 20. Liquid is then injected through the injection blind hole 24 on the first sealing cap 20. During injection, an injection needle containing the liquid to be atomized is inserted through the injection blind hole 24. After injection, the injection needle is removed. Due to the small needle hole and the elasticity of the first sealing cap 20, there will be no leakage or odor issues later. After the first liquid storage chamber is filled, the second liquid storage component 70 is installed in the second liquid storage chamber, followed by liquid injection. After injection, the second sealing cap 30 is installed. In addition to being used for liquid injection, the liquid injection blind holes 24 can also play a positioning role when assembling the nebulizer. For example, two liquid injection blind holes 24 can be opened. The actual number of liquid injection blind holes 24 can be opened as needed, and this application does not impose a specific limit.

[0079] In some embodiments, the atomizer can also perform a ventilation function. A first space is formed between the side wall of the liquid storage chamber 10 and the first liquid storage component 60, and a second space is formed between the first sealing cap 20 and the first liquid storage component 60. The first space, the second space, and the space inside the first atomizing tube 41 are interconnected. A third space is formed between the side wall of the liquid storage chamber 10 and the second liquid storage component 70, and a fourth space is formed between the second sealing cap 30 and the second liquid storage component 70. The third space, the fourth space, and the space inside the second atomizing tube 51 are interconnected.

[0080] Please refer to Figures 1 and 11. A first air guide groove 62 is formed on the side wall of the first liquid storage component 60, forming a first space. A first protrusion 22 is provided on the end of the first sealing cap 20 facing the first liquid storage component 60, and a first vent 23 is provided on the first protrusion 22. The first protrusion 22 is used to form a second space between the first sealing cap 20 and the first liquid storage component 60. The second space is connected to the first atomizing tube 41 through the first vent 23. A second air guide groove 72 is formed on the side wall of the second liquid storage component 70, forming a third space. A second protrusion 32 is provided on the end of the second sealing cap 30 facing the second liquid storage component 70, and a second vent 33 is provided on the second protrusion 32. The second protrusion 32 is used to form a fourth space between the second sealing cap 30 and the second liquid storage component 70. The fourth space is connected to the second atomizing tube 51 through the second vent 33.

[0081] The first protrusion 22 can be a ring-shaped structure or multiple circumferentially spaced block structures, and the first vent 23 can be a hole or a groove. The second protrusion 32 can also be a ring-shaped structure or multiple circumferentially spaced block structures, and the second vent 33 can be a hole or a groove. The number of the first venting groove 62 and the second venting groove 72 can be one or more, and there is no specific limitation. For example, a first venting groove 62 can be formed on each of the four sides of the first liquid storage component 60, and a second venting groove 72 can be formed on each of the four sides of the second liquid storage component 70.

[0082] As shown in Figures 1, 5, and 11, a ventilation hole 412 is formed on the wall of the first atomizing tube 41. The ventilation hole 412 is connected to the first vent position 23 and the first air guide groove 62. The ventilation hole 412 is used to balance the internal air pressure of the first liquid storage chamber and the first liquid storage component 60 with that of the first atomizing tube 41. The second liquid storage component 70 and the second atomizing tube 51 both abut against the second protrusion 32. The second vent position 33 is connected to the second air guide groove 72 and the second atomizing tube 51. The second vent position 33 is used to balance the internal air pressure of the second liquid storage chamber and the second liquid storage component 70 with that of the second atomizing tube 51.

[0083] When the first atomizing core 40 heats the liquid to be atomized stored in the first liquid storage chamber, the air in the first liquid storage chamber and the first liquid storage component 60 expands due to the heat. The expanded air compresses the first liquid storage component 60, causing leakage of the liquid to be atomized in the first liquid storage chamber. Correspondingly, this application provides a ventilation hole 412 on the first atomizing tube 41, allowing air exchange between the first liquid storage chamber and the first liquid storage component 60 and the inside of the first atomizing tube 41. The ventilation channel in the first liquid storage chamber is shown by the dotted line in Figure 2 (below the first sealing cap 20), thereby reducing the risk of leakage in the first liquid storage chamber under high and low temperature environments. Similarly, when the second atomizing core 50 heats the liquid to be atomized stored in the second liquid storage chamber, the air in the second liquid storage chamber and the second liquid storage component 70 expands due to the heat. The expanded air compresses the second liquid storage component 70, causing leakage of the liquid to be atomized in the second liquid storage chamber. Correspondingly, this application uses the second vent position 33 to exchange air between the second liquid storage chamber and the second liquid storage component 70 and the inside of the second atomizing tube 51. The air exchange channel in the second liquid storage chamber is shown by the dotted line in Figure 2 (above the first sealing cover 20), thereby reducing the risk of leakage in the second liquid storage chamber under high and low temperature environments.

[0084] By setting up corresponding ventilation structures in the first, second, third, and fourth spaces, the atomizer gains a ventilation function. When the atomizer has this function, the gas inside the liquid reservoir and the liquid storage component is connected to the outside. This prevents the liquid from being squeezed out of the reservoir due to gas expansion during use, especially in high and low temperature environments, thus avoiding leakage. Furthermore, ventilation facilitates smoother liquid delivery, ensuring optimal atomizer performance.

[0085] In some embodiments, a fifth space is formed between the first liquid reservoir 60 and the bottom 12, and the fifth space is connected to the first space. A sixth space is formed between the first sealing cap 20 and the second liquid reservoir 70, and the sixth space is connected to the third space. For example, corresponding ribs are provided on the bottom 12 to form the fifth space. Referring to Figure 10, multiple exhaust ports 25 are provided on the end face of the first sealing cap 20 facing the second liquid reservoir 70. For example, a ridge is provided on the outer periphery of the end of the first sealing cap 20 facing the second liquid reservoir 70, and four spaced exhaust ports 25 are provided on the ridge. The second liquid reservoir 70 abuts against the ridge, and the ridge creates a sixth space between the second liquid reservoir 70 and the first sealing cap 20. The sixth space is connected to the third space (i.e., the second air guide groove 72) through the exhaust ports 25. In this way, the atomizer can achieve more complete exhaust, and the gas is finally discharged through the mouthpiece on the side of the second vent 31. Otherwise, if the gas cannot be discharged in time, it is easy to cause leakage problems.

[0086] Please refer to Figures 1-4. The atomizer also includes an airflow switch sleeve 90. A mounting groove 17 is provided on the outer side of the bottom 12 of the liquid reservoir 10, corresponding to the position of the air inlet 13. The airflow switch sleeve 90 and the mounting groove 17 are connected; for example, the airflow switch sleeve 90 and the mounting groove 17 can be detachably sleeved together. The airflow switch sleeve 90 is used to install an airflow switch (not shown), which is used to connect to the control board. The airflow switch sleeve 90 can be a silicone sleeve, and the airflow switch can be a microphone, a pressure sensor, or a pneumatic flow rate sensor, etc. The airflow switch is used to detect the airflow status of the atomizer to determine whether the atomizer is in use, so as to supply power to the atomizing coil in the atomizer in a timely manner. For example, as shown in Figure 2, when the user uses the atomizer, under the user's inhalation action, the external airflow passes sequentially through the air inlet 13, the first atomizing tube 41, the first vent 21, the second atomizing tube 51, and the second vent 31. At this time, the airflow switch senses the airflow and supplies power to the required atomizing coil.

[0087] In this embodiment, the number of atomizing cores is set to two, namely the first atomizing core 40 and the second atomizing core 50. Different atomizing cores are used to correspond to different flavors of liquid to be atomized, and users can choose to use them according to their needs.

[0088] An atomizing device includes a power supply and an atomizer, wherein the atomizer is the atomizer in the above embodiment, and the power supply and the atomizer are electrically connected.

[0089] The power supply includes a power source and a control board. The power source supplies power to the required atomizing coils, and the control board controls the operating status of the corresponding atomizing coils.

[0090] Please refer to Figures 3 and 4. The bottom 12 of the liquid storage tank 10 is provided with multiple mounting parts 18. The atomizer is connected to the power supply through the mounting parts 18. For example, the mounting parts 18 are snap-fit, and the power supply is provided with corresponding fasteners. The atomizer and the power supply are detachably connected by snap-fit, so as to facilitate the replacement of different atomizers, such as replacing atomizers containing different flavored liquids to be atomized. This makes the designed atomizing device more versatile and flexible in use, realizing the multi-purpose nature of the atomizing device. In other embodiments, the atomizer and the power supply can also be connected in a non-detachable manner, for example, when the atomizing device is a disposable product.

[0091] The atomizing device in this application embodiment includes the atomizer in the above embodiment, and therefore also has the advantages of the atomizer in the above embodiment, so it will not be described again here.
