[0039] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0040] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0041] An atomizer is provided in one embodiment of the present application. 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 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 Figure 1-Figure 11 The atomizer provided in the present application includes: a liquid storage tank 10, a first sealing cover 20, a second sealing cover 30, a first atomization core 40 and a second atomization core 50.

[0043] The liquid storage bin 10 has a bin opening 11 and a bin bottom 12, and an air inlet 13 is provided on the bin bottom 12. The liquid storage bin 10 is similar to a cylindrical structure, and the bin opening 11 of the liquid storage bin 10 corresponds to the barrel opening of the cylindrical structure, and the bin bottom 12 of the liquid storage bin 10 corresponds to the barrel 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 axially into a first liquid storage chamber and a second liquid storage chamber. 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 formed on 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 respectively connected to the air inlet 13 and the first ventilation hole 21. 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 ventilation hole 21 and the second ventilation hole 31. The second atomizer core 50 is used for heating and atomizing 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 in the above embodiment is used, by fixing the first sealing cover 20 in the liquid storage tank 10, the space in the liquid storage tank 10 is axially divided into a first liquid storage chamber and a second liquid storage chamber, and the second sealing cover 30 is fixed at the chamber opening 11, so that the liquid storage tank 10 and the first sealing cover 20 enclose a relatively sealed first liquid storage chamber, and the liquid storage tank 10, the first sealing cover 20 and the second sealing cover 30 enclose a relatively sealed second liquid storage chamber. Different flavors of liquid to be atomized can be stored in the first liquid storage chamber and the second liquid storage chamber, and the first atomization core 40 in the first liquid storage chamber and the second atomization core 50 in the second liquid storage chamber can be combined to heat and atomize the corresponding flavor of liquid to be atomized as needed. When switching to heat the liquid to be atomized of different flavors, the corresponding atomization core can be switched, and there is no need to design other switching structures, which effectively simplifies the structure of providing a multi-flavor atomizer, thereby simplifying the assembly process of the atomizer and reducing the manufacturing cost of the atomizer. Correspondingly, the assembly process of the atomizer device containing the atomizer can also be simplified, and the manufacturing cost of the atomizer device can be reduced. 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 wall of the liquid storage bin 10, the bottom 12 of the liquid storage bin 10 and the first sealing cover 20, and the second liquid storage chamber is formed by the side wall of the liquid storage bin 10, the first sealing cover 20 and the second sealing cover 30. The air inlet 13, the first atomizing core 40, the first ventilation hole 21, the second atomizing core 50 and the second ventilation hole 31 are connected in sequence to form a complete air flow channel. The first liquid storage chamber and the second liquid storage chamber share a liquid storage bin 10. When using the atomizer to inhale liquids to be atomized of different flavors, the external air flow can share an air flow channel. There is no need to set up multiple liquid storage bins 10 and multiple air flow channels based on the setting of multiple flavors of liquids to be atomized, and there is no need to set up a switching structure based on the setting of multiple flavors of liquids to be atomized, such as a rotating structure, to align the liquid storage chamber and the suction nozzle corresponding to the liquid to be atomized of the flavor to be inhaled. The atomizer designed in this application effectively simplifies the structural design, simplifies the material cost and the assembly cost.

[0051] To ensure the sealing effect and the convenience of installation, the first sealing cover 20 and the second sealing cover 30 can be made of elastic plastic or rubber, for example, the first sealing cover 20 and the second sealing cover 30 are made of silicone. The first sealing cover 20 not only separates the liquid storage chamber, but also separates the liquid to be atomized in the first liquid storage chamber and the liquid to be atomized in the second liquid storage chamber, so as to prevent the liquid to be atomized in different liquid storage chambers from mixing and causing the liquid to have a different taste, thereby better ensuring the user's inhalation taste when using the atomizer or the atomizing device containing the 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 cavity, 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, and 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 cavity, 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, and 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 close to 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 through a first sealing cover 20, and 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 component 60 or liquid storage cotton in the first liquid storage chamber is shortened, and the length of the second liquid storage component 70 or liquid storage cotton in the second liquid storage chamber is shortened, which reduces the risk of leakage caused by 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 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, when the user prefers the taste of the liquid to be atomized in the second liquid storage chamber, the length of the second liquid storage chamber can be set 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. Correspondingly, the number of the first sealing covers 20 is increased, the liquid storage bin 10 is axially divided into three liquid storage chambers, and liquids to be atomized of different flavors are stored in the three liquid storage chambers, and three corresponding atomization cores are set at the same time. 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 bin 10 is effectively shortened by the first sealing cover 20, thereby avoiding the problem of leakage caused by excessive length of the liquid storage part or liquid storage cotton.

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

[0059] In order to facilitate the fixing of the adapter tube 80, the side wall of the adapter tube 80 abuts against the first vent hole 21. In order to ensure the sealing of the first vent hole 21, a plurality of sealing convex rings are arranged on the side wall of the first vent hole 21. The sealing convex rings 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. Through the adapter tube 80, the first atomization tube 41 and the second atomization tube 51 can be indirectly connected, which is convenient for the assembly of the atomizer. At the same time, it is also convenient to conduct the first atomization tube 41 and the second atomization tube 51, that is, the first atomization tube 41 and the second atomization tube 51 can be connected through the space in 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 integral 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 atomization core 40 further includes a first liquid guide member 42 and a first heating member 43, the first liquid guide member 42 is annular columnar, the outer wall of the first liquid guide member 42 is fixed to the inner wall of the first atomization tube 41, the first heating member 43 is fixed to the inner wall of the first liquid guide member 42, and the two ends of the internal channel of the first liquid guide member 42 are respectively connected with the channel of the first atomization tube 41 near the air inlet 13 and the channel of the first atomization tube 41 near the transfer tube 80. The second atomization 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 columnar, the outer wall of the second liquid guide member 52 is fixed to the inner wall of the second atomization tube 51, the second heating member 53 is fixed to the inner wall of the second liquid guide member 52, and the two ends of the internal channel of the second liquid guide member 52 are respectively connected with the channel of the second atomization tube 51 near the transfer tube 80 and the channel of the second atomization tube 51 near 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 provided 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, the second atomizing tube 51 is also provided with a corresponding liquid guide hole 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 guide 52, and convert the liquid to be atomized on the second liquid guide 52 into an aerosol that can be inhaled. The first heating element 43 and the second heating element 53 can be a mesh, wire, or sheet-like resistor structure, and this application does not impose any specific restrictions.

[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 provided on the outer wall of the adapter tube 80, and the lead position 81 is plugged with a part of the second lead 54.

[0064] The lead position 81 is, for example, a groove or hole opened on the outer wall of the transfer tube 80. The lead position 81 can fix part of the second lead 54 to avoid the problem of poor contact caused by the heating and shaking of the second lead 54 and deformation of the second heating element 53. The setting of the lead position 81 can better ensure the working state of the second atomizer core 50.

[0065] See also Fig. 9, a protrusion 82 is provided on the side wall of the transfer tube 80, and the two ends of the protrusion 82 are respectively in contact with the first atomization tube 41 and the second atomization tube 51. The protrusion 82 can be specifically a protruding ring structure or a convex block structure. When the protrusion 82 is a convex block structure, the protrusion 82 can be provided in plurality. On the one hand, it can be in contact with the first atomization tube 41 and the second atomization tube 51 on both sides to play a limiting role. On the other hand, the plurality of protrusions 82 can provide sufficient support for the first atomization tube 41 and the second atomization tube 51. In order to facilitate the sleeve connection between the transfer tube 80 and the first atomization tube 41 and the second atomization tube 51, guide surfaces are respectively provided at the two ends of the transfer tube 80, and the guide surfaces are, for example, conical annular surfaces.

[0066] See also Fig. 9 A plurality of lead positions 81 are provided on the outer wall of the transfer tube 80, and the plurality of lead positions 81 are arranged at intervals around the axis of the transfer tube 80. Specifically, the lead positions 81 are lead grooves, for example. The plurality of lead positions 81 are arranged at intervals in the circumferential direction, and the alignment problem between the second lead 54 and the lead positions 81 does not need to be considered, that is, the second lead 54 can be inserted through any lead position 81, which facilitates the assembly of the atomizer. More preferably, the plurality of lead positions 81 are arranged at equal intervals around the axis of the transfer tube 80.

[0067] See also Figure 5-Figure 6 as well as Figure 8 The first atomizing tube 41 is provided with a notch 411 at one end thereof facing the second atomizing tube 51, and part of the second lead wire 54 passes over the notch 411 and is placed on the outer wall of the first atomizing tube 41. The notch 411, on the one hand, can play a role in positioning and limiting the assembly of the second lead wire 54, and on the other hand, the second lead wire 54 is placed on the outer side of the first atomizing tube 41 to prevent the second lead wire 54 from passing through the first liquid guide 42. Based on the function or setting purpose of the notch 411, in other embodiments, the notch 411 can also be replaced by a hole-shaped structure.

[0068] See also Figure 5-Figure 8 In the embodiment of the present application, part of the first lead 44 is placed on the outer side wall of the first atomizing tube 41, and the first lead 44 and the second lead 54 placed on the outer side wall of the first atomizing tube 41 merge, 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 centralized distribution of the leads is convenient for fixing the leads (abbreviation of the first lead 44 and the second lead 54), and for shortening the length of the leads. When the length of the leads 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.

[0069] Specifically, a lead hole 15 is provided on the bottom 12 of the tank, and the first lead 44 and the second lead 54 after merging pass through the lead hole 15 to 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 tank, and the lead hole 15 is placed in the slot or the fence-like structure, so that the lead 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, and the first lead 44 and the second lead 54 are configured as two, and the first lead 44 and the second lead 54 both have a positive pin and a negative pin, and 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 lead corresponding to the positive pin and the lead corresponding to the negative pin are placed separately through the two lead holes 15 to avoid the cross-over of the leads of different polarity pins in the same lead hole 15 to generate eddy currents, which may cause local overheating of the leads and affect the normal operation of the atomizer core. At the same time, the classification of the leads through the two lead holes 15 can also simplify the production and assembly method of the atomizer, for example, the assembly worker only needs to pass the leads through the corresponding lead holes 15.

[0071] Three wiring blind holes 16 are provided at one end of the bottom 12 of the warehouse away from the warehouse opening 11, and an electrode is arranged in each wiring blind hole 16. The electrode in each wiring blind hole 16 is electrically connected to at least one lead wire, and the lead wire refers to the first lead wire 44 or the second lead wire 54. For example, the positive electrode pin of the first lead wire 44 and the positive electrode pin of the second lead wire 54 are electrically connected to the electrode in the same wiring blind hole 16, and the negative electrode pin of the first lead wire 44 and the negative electrode pin of the second lead wire 54 are electrically connected to the electrodes in different wiring blind holes 16, or the negative electrode pin of the first lead wire 44 and the negative electrode pin of the second lead wire 54 are electrically connected to the electrode in the same wiring blind hole 16, and the positive electrode pin of the first lead wire 44 and the positive electrode pin of the second lead wire 54 are electrically connected to the electrodes in different wiring blind holes 16. 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 continuously. 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] The first lead 44 and the second lead 54 share a positive electrode or a negative electrode, and the first atomizer core 40 and the second atomizer core 50 are connected in parallel, which effectively simplifies the atomizer structure and reduces the difficulty of production and assembly. After the first atomizer core 40 and the second atomizer core 50 are connected in parallel, more working modes can be provided, for example, only the first atomizer core 40 works, only the second atomizer core 50 works, or the first atomizer core 40 and the second atomizer core 50 work synchronously, giving users a richer taste experience.

[0073] See also Figure 5 Specifically, the first lead 44 is provided with a first bent portion 441 and a second bent portion 442 along the axial direction, the first bent portion 441 is disposed at one end of the first liquid guide 42 away from the port 11, and the second bent portion 442 is disposed at one end of the first atomizing tube 41 away from the port 11. The second lead 54 is provided with a third bent portion 541, the third bent portion 541 is disposed at one end of the second liquid guide 52 away from the port 11, and the third bent portion 541 is located between the second liquid guide 52 and the transfer tube 80.

[0074] The first bending portion 441, the second bending portion 442 and the third bending portion 541 are all right-angle bending portions. The first bending portion 441 allows the first lead 44 to be assembled more closely 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 bending portion 442 allows the first lead 44 to be assembled more closely when it passes through the inner wall of the first atomizing tube 41. The third bending portion 541 allows the second lead 54 to be assembled more closely when it switches from the inner wall of the second liquid guide 52 to the outer side of the first atomizing tube 41. Through the preset bending portions, multiple leads can be assembled more compactly and neatly in the atomizer, reducing the impact on the air flow channel.

[0075] See also Fig.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 bin 10 and at a position corresponding to the air inlet 13. When assembling the atomizer, the first atomization core 40 and the second atomization core 50 are connected in advance through the adapter tube 80, and the end of the first atomization 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 cavity, 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 eye 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 cavity is completed, the second liquid storage component 70 is assembled in the second liquid storage cavity, and then the second liquid storage cavity is injected. After the injection is completed, the second sealing cover 30 is assembled. The blind injection holes 24 are used not only for injection but also for positioning when assembling the atomizer. For example, two blind injection holes 24 are provided. The actual number of blind injection holes 24 is determined according to needs and is not specifically limited in this application.

[0077] Preferably, the atomizer can also realize a ventilation function. A first space is formed between the side wall of the liquid storage bin 10 and the first liquid storage member 60, a second space is formed between the first sealing cover 20 and the first liquid storage member 60, and the first space, the second space, and the space in the first atomization tube 41 are interconnected. A third space is formed between the side wall of the liquid storage bin 10 and the second liquid storage member 70, a fourth space is formed between the second sealing cover 30 and the second liquid storage member 70, and the third space, the fourth space, and the space in the second atomization tube 51 are interconnected.

[0078] See also Figure 1 and Fig.11 A first air guide groove 62 is provided on the side wall of the first liquid storage member 60, and a first space is formed in the first air guide groove 62. A first protrusion 22 is provided on the end of the first sealing cover 20 facing the first liquid storage member 60, and a first ventilation position 23 is provided 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 through the first ventilation position 23. A second air guide groove 72 is provided on the side wall of the second liquid storage member 70, and a third space is formed in the second air guide groove 72. A second protrusion 32 is provided on the end of the second sealing cover 30 facing the second liquid storage member 70, and a second ventilation position 33 is provided 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 through the second ventilation position 33.

[0079] The first protrusion 22 may be an annular structure or a plurality of block structures spaced apart circumferentially, and the first ventilation position 23 may be a hole or a groove. The second protrusion 32 may also be an annular structure or a plurality of block structures spaced apart circumferentially, and the second ventilation position 33 may be a hole or a groove. The number of the first air guide groove 62 and the second air guide groove 72 may be one or more, and is not specifically limited. For example, a first air guide groove 62 is respectively provided on the four side walls of the first liquid storage member 60, and a second air guide groove 72 is respectively provided on the four side walls of the second liquid storage member 70.

[0080] like Figure 1 , Figure 5 and Fig.11 As shown, a ventilation hole 412 is provided on the tube wall of the first atomizing tube 41, and the ventilation hole 412 is communicated with the first ventilation position 23 and the first air guide groove 62, and the ventilation hole 412 is used to balance the internal air pressure of the first liquid storage cavity and the first liquid storage member 60 and the first atomizing tube 41. The second liquid storage member 70 and the second atomizing tube 51 are both in contact with the second protrusion 32, and the second ventilation position 33 and the second air guide groove 72 are communicated with the second atomizing tube 51, and the second ventilation position 33 is used to balance the internal air pressure of the second liquid storage cavity and the second liquid storage member 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, and 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 atomization 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 atomization 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 setting corresponding ventilation structures in the first space, the second space, the third space and the fourth space, the atomizer has a ventilation function. When the atomizer has a ventilation function, the gas in the liquid storage chamber and the liquid storage part are connected to the outside. In this way, when the atomizer is used, in a high or low temperature environment, the liquid to be atomized in the liquid storage part 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 is also convenient for the atomized liquid to be transmitted more smoothly, ensuring the use effect of the atomizer.

[0083] 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 Fig.10 , a plurality of exhaust ports 25 are provided on one end surface of the first sealing cover 20 facing the second liquid storage member 70, for example, a convex ridge is provided on the outer periphery of one end of the first sealing cover 20 facing the second liquid storage member 70, and four exhaust ports 25 are provided on the convex ridge, and the second liquid storage member 70 abuts against the convex ridge, and the convex ridge makes a sixth space between the second liquid storage member 70 and the first sealing cover 20, and the sixth space is connected to the third space (i.e., the second air guide groove 72) through the exhaust port 25. In this way, the inside of the atomizer can be more fully exhausted, and the gas is finally discharged through the suction nozzle on one side of the second vent hole 31, otherwise if the gas cannot be discharged in time, it is easy to cause leakage.

[0084] See also Figure 1-Figure 4 The atomizer also includes an airflow switch cover 90. A mounting groove 17 is provided at the outer side of the bottom 12 of the liquid storage bin 10 and at a position corresponding to 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 atomizer 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 atomization tube 41, the first ventilation hole 21, the second atomization tube 51 and the second ventilation hole 31 in sequence. At this time, the airflow switch senses the airflow flow and supplies power to the required atomization 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 and used according to user needs.

[0086] An atomization device comprises 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, and the atomizer is connected to the power supply through the mounting portions 18, for example, the mounting portions 18 are buckles, and corresponding buckle positions are provided on the power supply, and the atomizer and the power supply are detachably connected in a buckle manner, so as to facilitate the replacement of different atomizers, for example, replacing atomizers containing different flavors of liquid to be atomized, so that the designed atomizing device has a wider range of uses or flexibility of use, 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, for example, when the atomizing device is a disposable product.
