Description

Technical Field

[0001] The present application relates to the field of atomization technology, and in particular to an atomizer and an atomization device. Background Art

[0002] An atomizer, as a product for atomization, includes a power supply and an atomizer. The power supply provides electrical energy and control to the atomizer, while the atomizer heats and atomizes the atomized substance. Different atomized substances have different flavors, and traditional atomizers that only offer a single flavor are no longer sufficient to meet user needs. Therefore, atomizers need to store a variety of atomized substances to provide users with a variety of inhalable flavors. However, current atomizers that can provide multiple flavors are generally constructed by stacking two or more oil tank assemblies, resulting in complex structures, complicated assembly processes, and high costs.

[0038] The present application is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0039] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0040] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0041] In one embodiment of the present application, an atomizer is provided. The atomizer is a part of the structure of the atomizing device, and is used to heat and atomize the 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, the liquid to be atomized is converted into an aerosol.

[0042] See also Figures 1-11 The atomizer provided in this application includes: a liquid storage tank 10, a first sealing cover 20, a second sealing cover 30, a first atomizing core 40 and a second atomizing core 50.

[0043] The liquid storage tank 10 has a tank opening 11 and a tank bottom 12, with an air inlet 13 formed on the tank bottom 12. The liquid storage tank 10 is similar to a cylindrical structure, with the tank opening 11 of the liquid storage tank 10 corresponding to the cylinder opening of the cylindrical structure, and the tank bottom 12 of the liquid storage tank 10 corresponding to the cylinder bottom of the cylindrical structure.

[0044] The first sealing cover 20 is fixed in the liquid storage bin 10 and divides the liquid storage bin 10 into a first liquid storage chamber and a second liquid storage chamber in the axial direction. The first liquid storage chamber is located near the bin bottom 12 and the second liquid storage chamber is located near the bin opening 11. A first vent hole 21 is provided on the first sealing cover 20.

[0045] The second sealing cover 30 is fixed to the port 11 . A second vent hole 31 is defined in the second sealing cover 30 . The second vent hole 31 is also the air outlet of the atomizer.

[0046] The first atomizer core 40 is disposed in the first liquid storage chamber. Two ends of the first atomizer core 40 are connected to the air inlet 13 and the first air vent 21 respectively. The first atomizer core 40 is used to heat and atomize the liquid to be atomized stored in the first liquid storage chamber.

[0047] The second atomizer core 50 is disposed in the second liquid storage chamber. Two ends of the second atomizer core 50 are respectively connected to the first vent 21 and the second vent 31. The second atomizer core 50 is used to heat and atomize the liquid to be atomized stored in the second liquid storage chamber.

[0048] The first atomizing core 40 includes a first lead wire 44 , and the second atomizing core 50 includes a second lead wire 54 . The first lead wire 44 and the second lead wire 54 are located on the same side of the air inlet 13 .

[0049] The atomizer of the above embodiment is configured by securing a first sealing cap 20 within the liquid reservoir 10, dividing the space within the reservoir 10 axially into a first liquid storage chamber and a second liquid storage chamber. A second sealing cap 30 is secured to the reservoir opening 11, thereby forming a relatively sealed first liquid storage chamber enclosed by the liquid reservoir 10 and the first sealing cap 20, and a relatively sealed second liquid storage chamber enclosed by the liquid reservoir 10, the first sealing cap 20, and the second sealing cap 30. The first and second liquid storage chambers can store liquids of different flavors to be atomized. Combined with the first atomizer core 40 within the first liquid storage chamber and the second atomizer core 50 within the second liquid storage chamber, the corresponding flavor of liquid can be heated and atomized as needed. When switching between heating different flavors of liquid to be atomized, the corresponding atomizer core is simply switched, eliminating the need for designing additional switching mechanisms. This effectively simplifies the structure of the multi-flavor atomizer, thereby simplifying the assembly process of the atomizer and reducing the manufacturing cost of the atomizer. This also simplifies the assembly process of an atomizer device containing the atomizer and reduces the manufacturing cost of the atomizer device. The first lead 44 and the second lead 54 are located on the same side of the air inlet 13, which facilitates assembly and simplifies the atomizer structure.

[0050] For details, please refer to Figure 1-Figure 2 The first liquid storage chamber is formed by the side walls of the liquid storage tank 10, the bottom 12 of the liquid storage tank 10, and the first sealing cover 20, and the second liquid storage chamber is formed by the side walls of the liquid storage tank 10, the first sealing cover 20, and the second sealing cover 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 connected in sequence to form a complete airflow channel. The first liquid storage chamber and the second liquid storage chamber share the same liquid storage tank 10. When using the atomizer to inhale liquids to be atomized of different flavors, the external airflow can share the same airflow channel. There is no need to set up multiple liquid storage tanks 10 and multiple airflow channels based on the settings of multiple flavors of liquids to be atomized, let alone set up a switching structure based on the settings of multiple flavors of liquids to be atomized, such as a rotating structure, to align the liquid storage chamber and the mouthpiece corresponding to the flavor of liquid to be atomized to be inhaled. The atomizer designed in this application effectively simplifies the structural design, reduces material costs and assembly costs.

[0051] To ensure a good seal and facilitate installation, the first and second sealing covers 20 and 30 can be made of elastic plastic or rubber. For example, both the first and second sealing covers 20 and 30 can be made of silicone. The first sealing cover 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 the liquids to be atomized from mixing and causing flavor contamination, thereby better ensuring the user's inhalation experience when using the atomizer or an atomizing device containing an atomizer.

[0052] See also Figure 1-Figure 2The atomizer further includes a first liquid storage member 60 and a second liquid storage member 70. The first liquid storage member 60 is disposed in the first liquid storage chamber, and a first atomization channel 61 is formed in the first liquid storage member 60. The two ends of the first atomization channel 61 are respectively connected to the air inlet 13 and the first ventilation hole 21. The first atomization core 40 is disposed in the first atomization channel 61. The second liquid storage member 70 is disposed in the second liquid storage chamber, and a second atomization channel 71 is formed in the second liquid storage member 70. The two ends of the second atomization channel 71 are respectively connected to the first ventilation hole 21 and the second ventilation hole 31. The second atomization core 50 is disposed in the second atomization channel 71.

[0053] Among them, the first liquid storage component 60 is used to absorb and store the liquid to be atomized in the first liquid storage cavity, and the second liquid storage component 70 is used to absorb and store the liquid to be atomized in the second liquid storage cavity. For example, the first liquid storage component 60 and the second liquid storage component 70 are both liquid storage cotton, and the liquid to be atomized is absorbed and stored through the porous structure on the liquid storage cotton.

[0054] When the liquid storage cotton in the liquid storage bin 10 of the atomizer is too long, due to gravity, the atomized liquid will accumulate at the bottom of the liquid storage cotton, that is, accumulate at one end of the liquid storage cotton near the bin bottom 12. After the atomized liquid accumulates, leakage is likely to occur.

[0055] Correspondingly, the present application divides the liquid storage tank 10 axially into a first liquid storage chamber and a second liquid storage chamber by the first sealing cover 20. The first liquid storage chamber and the second liquid storage chamber are shorter in length relative to the liquid storage tank 10 in the axial direction. For example, the length of the first liquid storage chamber is approximately half of the length of the liquid storage tank 10, and the length of the second liquid storage chamber is also approximately half of the length of the liquid storage tank 10. Correspondingly, the length of the first liquid storage member 60 or liquid storage cotton in the first liquid storage chamber is shortened, and the length of the second liquid storage member 70 or liquid storage cotton in the second liquid storage chamber is shortened, thereby reducing the risk of leakage caused by accumulation of atomized liquid at the bottom of the liquid storage cotton when the liquid storage cotton is too long. It should be noted that the length mentioned here refers to the length along the axial direction of the liquid storage tank 10.

[0056] The length ratio of the first liquid storage chamber and the second liquid storage chamber 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. The length of the first liquid storage chamber and the second liquid storage chamber is not specifically limited in this application and can be set according to actual conditions.

[0057] In addition to the design method of containing two flavors of liquid to be atomized, the atomizer designed in the present application can also include three or four flavors of liquid to be atomized. For example, the atomizer contains three flavors of liquid to be atomized. Accordingly, the number of the first sealing covers 20 is increased, the liquid storage tank 10 is axially divided into three liquid storage chambers, and the liquids to be atomized of different flavors are stored in the three liquid storage chambers, and three corresponding atomizing cores are provided. In other embodiments, the atomizer designed in the present application can also include only one flavor of liquid to be atomized, that is, the same flavor of liquid to be atomized is stored in the first liquid storage chamber and the second liquid storage chamber. At this time, the length of the liquid storage part or liquid storage cotton in the liquid storage tank 10 is effectively shortened by the first sealing cover 20, thereby avoiding the problem of leakage caused by the liquid storage part or liquid storage cotton being too long.

[0058] See also Figure 1-Figure 2 In the embodiment of the present application, the atomizer further includes an adapter tube 80, the first atomizer core 40 further includes a first atomizer tube 41, and the second atomizer core 50 further includes a second atomizer tube 51. The two ends of the adapter tube 80 are respectively connected to the first atomizer tube 41 and the second atomizer tube 51. Taking the connection between the adapter tube 80 and the first atomizer tube 41 as an example, the adapter tube 80 can be connected to the outside of the first atomizer tube 41, or the adapter tube 80 can be connected to the inside of the first atomizer tube 41. The connection between the adapter tube 80 and the second atomizer tube 51 is similar and will not be described here.

[0059] To facilitate the securing of the adapter tube 80, the sidewall of the adapter tube 80 abuts the first vent hole 21. To ensure the sealing of the first vent hole 21, multiple rings are provided on the sidewalls of the first vent hole 21. The rings abut the sidewalls 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 enables an indirect connection between the first atomizing tube 41 and the second atomizing tube 51, facilitating assembly of the atomizer. It also facilitates the communication between the first atomizing tube 41 and the second atomizing tube 51, that is, the first atomizing tube 41 and the second atomizing tube 51 can be connected through the space within the adapter tube 80.

[0060] In other embodiments, the adapter tube 80 may not be provided, and the first atomization tube 41 and the second atomization tube 51 may be an integrated structure, or the first atomization tube 41 and the second atomization tube 51 may be two independent parts that abut against each other.

[0061] See also Figure 5As shown, in the embodiment of the present application, specifically, the first atomizer core 40 further includes a first liquid guide member 42 and a first heating member 43. The first liquid guide member 42 is annular and cylindrical, and the outer wall of the first liquid guide member 42 is fixed to the inner wall of the first atomizer tube 41. The first heating member 43 is fixed to the inner wall of the first liquid guide member 42. The two ends of the internal channel of the first liquid guide member 42 are respectively connected to the channel of the first atomizer tube 41 on the side close to the air inlet 13 and the channel of the first atomizer tube 41 on the side close to the transfer tube 80. The second atomizer core 50 further includes a second liquid guide member 52 and a second heating member 53. The second liquid guide member 52 is also annular and cylindrical, and the outer wall of the second liquid guide member 52 is fixed to the inner wall of the second atomizer tube 51. The second heating member 53 is fixed to the inner wall of the second liquid guide member 52. The two ends of the internal channel of the second liquid guide member 52 are respectively connected to the channel of the second atomizer tube 51 on the side close to the transfer tube 80 and the channel of the second atomizer tube 51 on the side close to the second vent 31.

[0062] Among them, the first liquid guide member 42 and the second liquid guide member 52 are used to absorb and transfer the liquid to be atomized. For example, the first liquid guide member 42 and the second liquid guide member 52 are both liquid guide members made of liquid guide cotton or porous ceramics. Taking the first liquid guide member 42 as an example, a corresponding liquid guide hole is opened on the first atomizing tube 41 to allow the adjacent first liquid storage member 60 and the first liquid guide member 42 to contact each other. The first liquid guide member 42 in contact with the first liquid storage member 60 can absorb the liquid to be atomized on the first liquid storage member 60 and transfer the absorbed liquid to be atomized to the inner wall of the first liquid guide member 42. Similarly, a corresponding liquid guide hole is also opened on the second atomizing tube 51 to allow the adjacent second liquid storage member 70 and the second liquid guide member 52 to 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 guide member 42, and convert the liquid to be atomized on the first liquid guide member 42 into an aerosol that can be inhaled. 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 convert the atomized liquid on the second liquid-guiding element 52 into an aerosol that can be inhaled. The first heating element 43 and the second heating element 53 can be a mesh, filament, or sheet-like resistor structure, and this application does not specifically limit this.

[0063] See also Figure 5-Figure 9 The two ends of the adapter tube 80 are respectively sleeved in the first atomizing tube 41 and the second atomizing tube 51. A lead position 81 is opened on the outer wall of the adapter tube 80, and the lead position 81 is plugged into a part of the second lead 54.

[0064] The lead-in slot 81 is, for example, a slot or hole formed on the outer wall of the adapter tube 80. This slot 81 secures a portion of the second lead 54, preventing heat and vibration of the second lead 54, which could lead to poor contact and deformation of the second heating element 53. The provision of the lead-in slot 81 further ensures the working condition of the second atomizer core 50.

[0065] See also Figure 9The side wall of the adapter tube 80 is provided with a raised portion 82, and the two ends of the raised portion 82 respectively abut against the first atomizing tube 41 and the second atomizing tube 51. The raised portion 82 can specifically be a raised ring structure or a bump structure. When the raised portion 82 is a bump structure, the raised portion 82 can be provided in plurality. On the one hand, it can abut against the first atomizing tube 41 and the second atomizing tube 51 on both sides to play a limiting role. On the other hand, the multiple raised portions 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. The guide surfaces are, for example, conical annular surfaces.

[0066] See also Figure 9 The outer wall of the adapter tube 80 defines a plurality of lead positions 81, spaced apart around the axis of the adapter tube 80. Specifically, the lead positions 81 may be, for example, lead grooves. The plurality of circumferentially spaced lead positions 81 eliminates the need to align the second lead 54 with the lead positions 81; the second lead 54 can be inserted through any lead position 81, facilitating assembly of the atomizer. More preferably, the plurality of lead positions 81 are spaced apart at equal intervals around the axis of the adapter tube 80.

[0067] See also Figure 5-Figure 6 as well as Figure 8 A notch 411 is defined at one end of the first atomizing tube 41 facing the second atomizing tube 51. A portion of the second lead wire 54 passes through the notch 411 and is positioned on the outer wall of the first atomizing tube 41. The notch 411 notches both position and limit the second lead wire 54 during assembly. Furthermore, by positioning the second lead wire 54 outside the first atomizing tube 41, it prevents the second lead wire 54 from passing through the first liquid-guiding member 42. In other embodiments, the notch 411 can be replaced with a hole-like structure, depending on its function or purpose.

[0068] See also Figure 5-Figure 8 In the embodiment of the present application, a portion of the first lead 44 is placed on the outer wall of the first atomizing tube 41, where the first lead 44 and the second lead 54 located on the outer wall of the first atomizing tube 41 converge, such that the first lead 44 and the second lead 54 are located on the same side of the first atomizing tube 41. This allows the first and second leads 44, 54 to be relatively concentrated, facilitating assembly. Furthermore, the centralized distribution of the leads facilitates securing the leads (referred to as the first and second leads 44, 54) and shortening their length. Shortening the lead length also helps reduce line resistance, thereby reducing energy loss and improving the energy efficiency of the atomizer and atomizing device containing the atomizer.

[0069] Specifically, a lead hole 15 is provided on the bottom 12 of the liquid storage tank, through which the first lead wire 44 and the second lead wire 54, after being combined, pass out of the liquid storage tank 10. More preferably, a slot or a fence-like structure can be provided on the bottom 12 of the liquid storage tank, and the lead hole 15 is placed within the slot or fence-like structure. In this way, the lead wire structure passing through the lead hole 15 can be guided and protected.

[0070] Two lead holes 15 are provided on the bottom 12 of the bin. The first lead 44 and the second lead 54 are each configured as two leads. The first lead 44 and the second lead 54 both have a positive pin and a negative pin. The positive pin of the first lead 44 and the positive pin of the second lead 54 pass through the same lead hole 15, and the negative pin of the first lead 44 and the negative pin of the second lead 54 pass through the same lead hole 15, but the positive pin and the negative pin pass through different lead holes 15. The two lead holes 15 separate the lead corresponding to the positive pin and the lead corresponding to the negative pin to avoid eddy currents when the leads of different polarity pins cross in the same lead hole 15, causing local overheating of the leads and affecting the normal operation of the atomizer core. At the same time, the classification of the leads by the two lead holes 15 can also simplify the production and assembly of the atomizer. For example, the assembly worker only needs to pass the lead through the corresponding lead hole 15.

[0071] Three wiring blind holes 16 are provided at one end of the bottom 12 of the bin facing away from the bin opening 11, and an electrode is provided in each wiring blind hole 16. The electrode in each wiring blind hole 16 is electrically connected to at least one lead, which refers to 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 wiring blind hole 16, and the negative pin of the first lead 44 and the negative pin of the second lead 54 are electrically connected to the electrodes in different wiring blind holes 16, respectively. Alternatively, the negative pin of the first lead 44 and the negative pin of the second lead 54 are electrically connected to the electrode in the same wiring blind hole 16, and the positive pin of the first lead 44 and the positive pin of the second lead 54 are electrically connected to the electrodes in different wiring blind holes 16, respectively. After the electrodes in the wiring blind holes 16 are connected to the pins of the corresponding leads, and the pins are connected to the corresponding electrodes, they can be inspected by a jig. If the assembly is qualified, the atomizer can be assembled. If the assembly is unqualified, it can be modified in time. If the lead pins and the control board are directly welded, problems such as cold welding and false welding are likely to occur. Since the pins and the control board are welded once, problems cannot be checked or corrected, which will result in higher production costs.

[0072] By sharing a common positive or negative electrode, the first and second leads 44, 54 connect the first and second atomizer cores 40, 50 in parallel, effectively simplifying the atomizer structure and reducing the difficulty of production and assembly. Connecting the first and second atomizer cores 40, 50 in parallel allows for more operating modes, such as operating only the first atomizer core 40, only the second atomizer core 50, or both simultaneously, providing users with a richer flavor experience.

[0073] See also Figure 5 Specifically, the first lead wire 44 is axially provided with a first bend 441 and a second bend 442. The first bend 441 is positioned at the end of the first liquid guide 42 facing away from the port 11, and the second bend 442 is positioned at the end of the first atomizing tube 41 facing away from the port 11. The second lead wire 54 is provided with a third bend 541. The third bend 541 is positioned at the end of the second liquid guide 52 facing away from the port 11 and is located between the second liquid guide 52 and the transfer tube 80.

[0074] The first bend 441, the second bend 442, and the third bend 541 are all right-angled bends. The first bend 441 allows the first lead 44 to fit more snugly when it switches from the inner wall of the first liquid-guiding member 42 to the inner wall of the first atomizing tube 41. Similarly, the second bend 442 allows the first lead 44 to fit more snugly when it passes through the inner wall of the first atomizing tube 41. The third bend 541 allows the second lead 54 to fit more snugly when it switches from the inner wall of the second liquid-guiding member 52 to the outside of the first atomizing tube 41. The pre-set bends make the assembly of multiple leads within the atomizer more compact and neat, reducing the impact on the airflow channel.

[0075] See also Figure 10 A liquid injection blind hole 24 is provided on the first sealing cover 20 , and a liquid injection blind hole 24 is provided on a side of the first sealing cover 20 facing the port 11 .

[0076] See also Figure 2A support ring 14 is provided in the bottom 12 of the liquid storage tank 10 and at a position corresponding to the air inlet 13. When assembling the atomizer, the first atomizing core 40 and the second atomizing core 50 are connected in advance through the adapter tube 80, and the end of the first atomizing tube 41 away from the adapter tube 80 is fixedly sleeved with the support ring 14. The first liquid storage component 60 is assembled in the first liquid storage chamber, and then the first sealing cover 20 is assembled, and then the liquid is injected through the injection blind hole 24 on the first sealing cover 20. When injecting liquid, an injection needle containing the liquid to be atomized is used to inject liquid through the injection blind hole 24. After the injection is completed, the injection needle is pulled out. Due to the small needle hole and the elasticity of the first sealing cover 20, there will be no leakage and odor problems in the later stage. After the injection of the first liquid storage chamber is completed, the second liquid storage component 70 is assembled in the second liquid storage chamber, and then the second liquid storage chamber is injected. After the injection is completed, the second sealing cover 30 is assembled. In addition to being used for liquid injection, the liquid injection blind holes 24 can also play a positioning role when assembling the atomizer. For example, the number of liquid injection blind holes 24 is two. The actual number of liquid injection blind holes 24 is opened as needed, and this application does not impose any specific restrictions.

[0077] Preferably, the atomizer can also implement a ventilation function. A first space is formed between the sidewall of the liquid reservoir 10 and the first liquid reservoir 60, and a second space is formed between the first sealing cover 20 and the first liquid reservoir 60. The first and second spaces are interconnected with the space within the first atomizing tube 41. A third space is formed between the sidewall of the liquid reservoir 10 and the second liquid reservoir 70, and a fourth space is formed between the second sealing cover 30 and the second liquid reservoir 70. The third and fourth spaces are interconnected with the space within the second atomizing tube 51.

[0078] See also Figure 1 and Figure 11 A first air guide groove 62 is defined on the sidewall of the first liquid storage member 60, forming a first space within the first air guide groove 62. A first protrusion 22 is defined on the end of the first sealing cover 20 facing the first liquid storage member 60, and a first vent position 23 is defined on the first protrusion 22. The first protrusion 22 is used to form a second space between the first sealing cover 20 and the first liquid storage member 60, and the second space is connected to the first atomization tube 41 via the first vent position 23. A second air guide groove 72 is defined on the sidewall of the second liquid storage member 70, and a third space is formed within the second air guide groove 72. A second protrusion 32 is defined on the end of the second sealing cover 30 facing the second liquid storage member 70, and a second vent position 33 is defined on the second protrusion 32. The second protrusion 32 is used to form a fourth space between the second sealing cover 30 and the second liquid storage member 70, and the fourth space is connected to the second atomization tube 51 via the second vent position 33.

[0079] The first raised portion 22 may be an annular structure or a plurality of circumferentially spaced block structures, and the first ventilation position 23 may be hole-shaped or groove-shaped. The second raised portion 32 may also be an annular structure or a plurality of circumferentially spaced block structures, and the second ventilation position 33 may be hole-shaped or groove-shaped. The number of the first air guide grooves 62 and the second air guide grooves 72 may be one or more, and is not specifically limited. For example, a first air guide groove 62 may be defined on each of the four sidewalls of the first liquid storage member 60, and a second air guide groove 72 may be defined on each of the four sidewalls of the second liquid storage member 70.

[0080] like Figure 1 、 Figure 5 and Figure 11 As shown, a ventilation hole 412 is defined in the wall of the first atomizing tube 41. The ventilation hole 412 communicates with the first ventilation 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, the first liquid storage element 60, and the first atomizing tube 41. The second liquid storage element 70 and the second atomizing tube 51 are both in contact with the second protrusion 32. The second ventilation position 33 communicates with the second air guide groove 72 and the second atomizing tube 51. The second ventilation position 33 is used to balance the internal air pressure of the second liquid storage chamber, the second liquid storage element 70, and the second atomizing tube 52.

[0081] When the first atomizer 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 member 60 will expand due to the heat. The expanded air will squeeze the first liquid storage member 60, causing the liquid to be atomized in the first liquid storage chamber to leak. Correspondingly, the present application provides a ventilation hole 412 on the first atomizer tube, so that the air in the first liquid storage chamber and the first liquid storage member 60 can be exchanged with the air inside the first atomizer tube. The ventilation channel in the first liquid storage chamber is as follows: Figure 2 As shown by the dotted line in the middle (below the first sealing cover 20), the risk of leakage in the high and low temperature environment of the first liquid storage chamber is reduced. 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 member 70 will expand due to the heat, and the expanded air will squeeze the second liquid storage member 70, causing the liquid to be atomized in the second liquid storage chamber to leak. Correspondingly, the present application exchanges the air in the second liquid storage chamber and the second liquid storage member 70 with the air inside the second atomizing tube 51 through the second ventilation position 33. The ventilation channel in the second liquid storage chamber is as shown in FIG. Figure 2 As shown by the dotted line in the middle (above the first sealing cover 20), the risk of leakage in the second liquid storage chamber under high and low temperature environments is reduced.

[0082] By providing corresponding ventilation structures in the first, second, third, and fourth spaces, the atomizer is endowed with a ventilation function. When the atomizer has a ventilation function, the gas in the liquid storage chamber and the liquid storage element is connected to the outside. In this way, when the atomizer is used, in high or low temperature environments, the liquid to be atomized in the liquid storage element will not be squeezed out due to gas expansion inside the atomizer, thereby avoiding leakage. At the same time, after the atomizer is ventilated, it also facilitates smoother transmission of the atomized liquid, ensuring the effectiveness of the atomizer.

[0083] More preferably, a fifth space is formed between the first liquid storage member 60 and the bottom 12, and the fifth space is connected to the first space. A sixth space is formed between the first sealing cover 20 and the second liquid storage member 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, see Figure 10 The first sealing cover 20 has a plurality of exhaust ports 25 formed on one end thereof facing the second liquid reservoir 70. For example, a ridge is provided on the outer periphery of the end of the first sealing cover 20 facing the second liquid reservoir 70, with four exhaust ports 25 spaced apart on the ridge. The second liquid reservoir 70 abuts against the ridge, creating a sixth space between the second liquid reservoir 70 and the first sealing cover 20. The sixth space is connected to the third space (i.e., the second air guide groove 72) via the exhaust ports 25. This allows for more complete exhaust within the atomizer, with the gas ultimately discharged through the nozzle on the side of the second vent 31. Otherwise, if the gas cannot be discharged in a timely manner, leakage may occur.

[0084] See also Figure 1-Figure 4 , the atomizer also includes an airflow switch cover 90, and a mounting groove 17 is provided at the outer side of the bottom 12 of the liquid storage tank 10 and the corresponding position of the air inlet 13. The airflow switch cover 90 is connected to the mounting groove 17, for example, the airflow switch cover 90 and the mounting groove 17 are detachably connected. The airflow switch cover 90 is used to install an airflow switch (not shown), and the airflow switch is used to connect to the control panel. The airflow switch cover 90 can be a silicone cover, and the airflow switch can be a microphone, an air pressure sensor, or a pneumatic flow rate sensor, etc. The airflow switch is used to detect the airflow state of the atomizer to determine whether the atomizer is in use, so as to power the atomizing core in the atomizer in time. For example, Figure 2 As shown, when the user uses the atomizer, under the user's inhalation action, the external air flow passes through the air inlet 13, the first atomizing tube 41, the first ventilation hole 21, the second atomizing tube 51 and the second ventilation hole 31 in sequence. At this time, the air flow switch senses the air flow and supplies power to the required atomizing core.

[0085] In the embodiment of the present application, the number of atomizer cores is set to two, namely the first atomizer core 40 and the second atomizer core 50. Different atomizer cores work corresponding to different flavors of liquid to be atomized, and can be selected according to user needs.

[0086] An atomization 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.

[0087] The power supply includes a power supply and a control board. The power supply is used to supply power to the required atomizer core, and the control board is used to control the working state of the corresponding atomizer core.

[0088] See also Figure 3-Figure 4 The bottom 12 of the liquid storage tank 10 is provided with a plurality of mounting portions 18, through which the atomizer is connected to the power supply. For example, the mounting portion 18 is a buckle, and a corresponding buckle position is provided on the power supply. The atomizer and the power supply are detachably connected by a buckle, so as to facilitate the replacement of different atomizers, such as replacing atomizers containing different flavors of liquid to be atomized. This makes the designed atomizing device have a wider range of uses or flexibility, and realizes the multi-purpose use of the atomizing device. In other embodiments, the atomizer and the power supply can also be connected in a non-detachable manner, such as when the atomizing device is a disposable product.

[0089] The atomizing device in the embodiment of the present application 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 in detail here.

[0090] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For those skilled in the art of the present application, based on the concept of the present application, they can also make some simple deductions, modifications or substitutions.
