[0034] Referring to FIG. 1 to FIG. 3 together, an atomization device provided in this embodiment of this application is explained now.

[0035] The atomization device includes at least two heating elements 500. Corresponding to each heating element 500, a liquid storage cavity 101, an atomization cavity 1021, and an air inlet channel 1022 are provided. The liquid inlet surface of each heating element 500 faces toward the liquid storage cavity 101, and the atomization surface of the heating element 500 faces toward the atomization cavity 1021. The air inlet channels 1022 are respectively communicated to corresponding atomization cavities 1021. The atomization device further includes an air outlet channel 1023. The atomization cavities 1021 are communicated to the air outlet channel 1023.

[0036] Two, three, four, or more heating elements 500 are provided. Corresponding to each heating element 500, the liquid storage cavity 101, the atomization cavity 1021, and the air inlet channel 1022 are provided, meaning that a quantity of liquid storage cavities 101, a quantity of atomization cavities 1021, and a quantity of air inlet channels 1022 are the same as a quantity of heating elements 500. For ease of description, the heating elements 500 and their corresponding liquid storage cavities 101, atomization cavities 1021, and air inlet channels 1022 can collectively be referred to as atomization units. Thus, the atomization device includes at least two atomization units which operate independently. Aerosols generated by the atomization units are directed from the atomization cavities 1021 to the air outlet channel 1023, are mixed at the air outlet channel 1023, and are finally inhaled by a user via the air outlet channel 1023. For a single atomization unit, an atomization substrate in the liquid storage cavity 101 enters the heating element 500 via the liquid inlet surface of the heating element 500. After being electrified, the heating element 500 generates heat to heat and atomize the atomization substrate to generate aerosols at the atomization surface. The aerosols are generated in the atomization cavity 1021. External air enters the atomization cavity 1021 through the air inlet channel 1022, carries away the aerosols in the atomization cavity 1021, and flows toward the air outlet channel 1023. The aerosols generated in the atomization cavities 1021 are inhaled by the user after being mixed at the air outlet channel 1023.

[0037] According to the atomization device in this embodiment of this application, through the arrangement of the at least two heating elements 500, corresponding to each heating element 500, the liquid storage cavity 101, the atomization cavity 1021, and the air inlet channel 1022 are provided, and the atomization device further includes the air outlet channel 1023. The atomization cavities 1021 are communicated to the air outlet channel 1023, so that aerosols generated in the atomization cavities 1021 can be inhaled by a user after being mixed in the air outlet channel 1023. When an atomization substrate capable of being heated to generate aerosols with different flavors is injected into the liquid storage cavities 101, aerosols with at least two mixed flavors can be obtained in the air outlet channel 1023. When an atomization substrate capable of being heated to generate aerosols with different effects is injected into the liquid storage cavities 101, aerosols with at least two effects can be obtained in the air outlet channel 1023, to meet usage needs of users.

[0038] In some embodiments, the atomization cavities 1021 are arranged around the center line of the air outlet channel 1023 or around an extension line of the center line. Specifically, when the atomization cavities 1021 and the air outlet channel 1023 at least partially overlap in the longitudinal direction of the atomization device, the atomization cavities 1021 are arranged around the center line of the air outlet channel 1023. When the atomization cavities 1021 and the air outlet channel 1023 do not overlap in the longitudinal direction of the atomization device, the atomization cavities 1021 are arranged around the extension line of the center line of the air outlet channel 1023. The longitudinal direction of the atomization device refers to an extension direction perpendicularly extending from one end of the atomization device to another end, namely a height direction of the atomization device when the atomization device is placed vertically. Due to the above configuration of this embodiment, the lengths of paths from the aerosols generated in the atomization cavities 1021 to the air outlet channel 1023 are the same, so that the aerosols generated in the air outlet channel 1021 can be mixed uniformly in the air outlet channel 1023. It can be understood that in other embodiments of this application, the atomization cavities 1021 may be arranged sequentially in a direction, and the air outlet channel 1023 is arranged on the same sides of the atomization cavities 1021, without imposing a unique limitation herein.

[0039] In some embodiments, referring to FIG. 2, corresponding liquid storage cavities 101, heating elements 500, atomization cavities 1021, and air inlet channels 1022 are distributed in the longitudinal direction of the atomization device. The liquid storage cavities 101 are distributed in the transverse direction of the atomization device.

[0040] The corresponding liquid storage cavities 101, heating elements 500, atomization cavities 1021, and air inlet channels 1022 are distributed in the longitudinal direction of the atomization device. This means that the liquid storage cavities 101, the heating elements 500, the atomization cavities 1021, and the air inlet channels 1022 are distributed in the longitudinal direction of the atomization device.

[0041] The liquid storage cavities 101 are distributed in the transverse direction of the atomization device. The transverse direction of the atomization device refers to a direction perpendicular to the longitudinal direction of the atomization device. When the liquid storage cavities 101 are distributed in the transverse direction of the atomization device, the heating elements 500 are also distributed in the transverse direction of the atomization device, the atomization cavities 1021 are also distributed in the transverse direction of the atomization device, and the air inlet channels 1022 are also distributed in the transverse direction of the atomization device. The above configuration implements a compact and orderly structural layout of the atomization units and ensures no mutual interference.

[0042] In some embodiments, referring to FIG. 2, the liquid storage cavity 101, the heating element 500, the atomization cavity 1021, and the air inlet channel 1022 in the same atomization unit are arranged sequentially in the longitudinal direction of the atomization device. The atomization substrate in the liquid storage cavity 101 can be directed to the heating element 500 under action of gravity. External atmosphere in the air inlet channel 1022 can upward enter the atomization cavity 1021 to carry the aerosols inside the atomization cavity 1021, and the external atmosphere carrying the aerosols upward enter the air outlet channel 1023 for user inhalation.

[0043] In some embodiments, as shown in FIG. 2, the atomization units are arranged around the air outlet channel 1023. That is, the atomization units are distributed in the circumferential direction of the atomization device. It can be understood that in other embodiments of this application, the atomization units may be arranged sequentially in the transverse direction of the atomization device. The air outlet channel 1023 is arranged on the same sides of the atomization units, without imposing a unique limitation herein.

[0044] In some specific embodiments, referring to FIG. 2 to FIG. 5, the atomization device includes two atomization units that are spaced apart from each other in the transverse direction of the atomization device. Specifically, the two atomization units are spaced apart from each other in the transverse direction in which the atomization device has a larger size. For example, the size of the atomization device in a first direction X is greater than the size of the atomization device in a second direction Y. The two atomization units are distributed in the first direction X. In each atomization unit, the liquid storage cavity 101, the heating element 500, the atomization cavity 1021, and the air inlet channel 1022 are arranged sequentially in the longitudinal direction of the atomization device. The air outlet channel 1023 extends in the longitudinal direction of the atomization device and is located at the center position between the two atomization units. The air outlet channel 1023 corresponds to the liquid storage cavity 101 and the heating element 500 in the longitudinal direction of the atomization device.

[0045] Specifically, both the liquid inlet surface and the atomization surface of the heating element 500 are perpendicular to the longitudinal direction of the atomization device. This means that the heating element 500 is arranged transversely to reduce a longitudinal space occupied by the heating element 500 in the atomization device.

[0046] In some embodiments, referring to FIG. 2 to FIG. 4, an isolation portion 210 for isolating the atomization cavities 1021 from each other is arranged between the atomization cavities 1021. The arrangement of the isolation portion 210 can prevent formation of vortexes when the aerosols in the atomization cavities 1021 are mixed from affecting the stability of an airflow.

[0047] In some embodiments, referring to FIG. 2, the isolation portion 210 at least partially extends into the air outlet channel 1023, and partitions an inlet of the air outlet channel 1023 for corresponding communication with the atomization cavities 1021. Specifically, the isolation portion 210 partitions the inlet of the air outlet channel 1023 into a plurality of inlet portions 10231 which are respectively configured to respectively introduce the aerosols in the atomization cavities 1021 into the air outlet channel 1023. In this embodiment, through the design in which the isolation portion 210 extends into the air outlet channel 1023, the aerosols in the atomization cavities 1021 will not be mixed before entering the air outlet channel 1023, thus avoiding the formation of the vortex and ensuring the stability of the airflow.

[0048] In some embodiments, referring to FIG. 2 to FIG. 4, the bottom of the isolation portion 210 has a first arc-shaped surface 211 configured to guide airflows in the atomization cavities 1021 to the inlet portions 10231, to ensure smooth switching of the airflows in the atomization cavities 1021 from the transverse direction to the longitudinal direction.

[0049] In some embodiments, referring to FIG. 2, the cross-sectional area of the inlet of the air outlet channel 1023 gradually decreases from bottom to top. The inner circumferential surface of the inlet of the air outlet channel 1023 is an arc-shaped surface or a curved surface, so that the airflows in the atomization cavities 1021 smoothly enter the air outlet channel 1023. This can ensure that the airflows are smooth, functions are stable in a use process, and negative phenomena such as blocked inhalation are avoided.

[0050] In some embodiments, the atomization device includes a suction nozzle 400, a liquid storage tank 100, an internal bracket 200, and a shell 300. The internal bracket 200 and the liquid storage tank 100 jointly enclose the atomization cavities 1021. The shell 300 is sleeved outside the internal bracket 200. The suction nozzle 400 is sleeved outside the liquid storage tank 100. The suction nozzle 400 is connected to the shell 300. The liquid storage cavities 101 are formed in the liquid storage tank 100. The air outlet channel 1023 penetrates through the liquid storage tank 100 and the suction nozzle 400. The air inlet channels 1022 are formed in the side surface of the internal bracket 200 facing toward the shell 300. By forming the air inlet channels 1022 on the side surface of the internal bracket 200 facing toward the shell 300, it is convenient to control a flow velocity of air and leave space for other structures. For example, the air inlet channels 1022 can be separated from a control unit 600, to facilitate air intake control, facilitate control of airflow noises, and also prevent liquid leakage to the control unit 600.

[0051] In some embodiments, referring to FIG. 5, the air inlet channels 1022 are formed on the side surface of the internal bracket 200 in the second direction Y. The air inlet channels 1022 are distributed in a spacing manner in the first direction X. A mounting cavity is formed on the other side surface of the internal bracket 200 in the second direction Y and is configured to mount the control unit 600, thereby isolating the air inlet channels 1022 from the control unit 600.

[0052] In some embodiments, referring to FIG. 5 and FIG. 9, the atomization device further includes one air inlet hole 1026 communicated to external atmosphere. One end of each air inlet channel 1022 is communicated to the air inlet hole 1026, and another end of each air inlet channel 1022 is communicated to each atomization cavity 1021. After the external atmosphere enters the atomization device via the air inlet hole 1026, the external atmosphere enters the corresponding atomization cavities 1021 from the air inlet channels 1022 to carry the aerosols into the air outlet channel 1023, and is inhaled by a user after being mixed in the air outlet channel 1023.

[0053] In some embodiments, the air inlet hole 1026 is formed in the center position of the side, facing away from the suction nozzle 400, of the shell 300. The air inlet channels 1022 are symmetrically distributed relative to the center line of the air inlet hole 1026. It can be understood that in other embodiments of this application, the atomization device may further include a plurality of air inlet holes 1026 communicated to the external atmosphere. One end of each air inlet channel 1022 is communicated to each air inlet hole 1026, and another end of each air inlet channel 1022 is communicated to each atomization cavity 1021. This means that the air intake of each atomization unit is independently set, and no unique limitation is imposed here.

[0054] In some embodiments, referring to FIG. 5, the air inlet channels 1022 are formed in the internal bracket 200. Specifically, the internal bracket 200 is inwards recessed in the second direction Y to form the air inlet channels 1022. The air inlet channels 1022 converge in the middle portion of the side, facing away from the liquid storage tank 100, of the internal bracket 200 to form a convergence port 1027, and are communicated to the air inlet holes 1026 of the shell 300. The second direction Y is perpendicular to the first direction X. The first direction X can be referred to as a left-right direction or width direction of the atomization device, and the second direction Y can be referred to as a front-back direction or thickness direction of the atomization device.

[0055] In some embodiments, the liquid storage tank 100 and the internal bracket 200 are distributed in the longitudinal direction of the atomization device and are connected to each other in a plugging manner. The internal bracket 200 is clamped to the shell 300, and the suction nozzle 400 and the shell 300 abut against each other in the longitudinal direction of the atomization device and are clamped to each other.

[0056] In some embodiments, referring to FIG. 2 and FIG. 4, one side of the internal bracket 200 facing toward the liquid storage tank 100 is recessed inward to form a groove. The middle position of the groove is directly opposite to the air outlet channel 1023 in the longitudinal direction, and the isolation portion 210 extends in the longitudinal direction from the bottom of the middle position of the groove into the air outlet channel 1023. The cross-sectional area of the bottom of the isolation portion 210 gradually decreases from bottom to top to form each first arc-shaped surface 211 on the surface.

[0057] In some embodiments, referring to FIG. 3, a throttle hole 1024 is formed in the bottom of each atomization cavity 1021, and communicates the atomization cavity 1021 to each air inlet channel 1022. Through the arrangement of the throttle hole 1024, an air flow rate can be adjusted to implement suction resistance control on the atomization unit, to meet inhalation needs of users.

[0058] In some embodiments, referring to FIG. 3 and FIG. 4, an air inlet column 220 is arranged in the atomization cavity 1021 and protrudes a preset height from the bottom of the atomization cavity 220. The bottom end of the air inlet column 220 is communicated to the throttle hole 1024. An airflow enters the air inlet column 220 after passing through the throttle hole 1024, which can ensure the direction of the airflow. Meanwhile, intake air is conveyed into the atomization cavity 1021 at the preset height through the air inlet column 220, thereby mitigating the problem that condensate in the atomization cavity 1021 flows into the air inlet channel 1022 and the mitigating the problem that the air inlet channel 1022 is blocked.

[0059] In some embodiments, referring to FIG. 3, the air inlet column 220 is roughly in a horn shape, so that the air at the outlet of the air inlet column 220 can be quickly dispersed to the surrounding region, to prevent the air from being condensed at the top.

[0060] In some embodiments, the longitudinal distance from the top end surface of the air inlet column 220 to the heating element 500 is greater than or equal to 0.5 mm, for example, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2.0 mm, or the like. In this embodiment, the longitudinal distance from the top end surface of the air inlet column 220 to the heating element 500 is limited to prevent air condensation of the air entering from the air inlet column 220 due to insufficient dispersion caused by the small distance between the air inlet column 220 and the heating element 500.

[0061] In some embodiments, the size of the air inlet column 220 and the size of the heating element 500 in the transverse direction of the atomization device are greater than 0.5 mm, for example, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, or 2.0 mm. In this way, the air in the air inlet column 220 can be in full contact with the aerosols to bring away the aerosols.

[0062] In some embodiments, referring to FIG. 3, an arc-shaped guide surface 110 is formed at a position, corresponding to the position of the outlet of the air inlet column 220, on the inner wall of the top side of the atomization cavity 1021. The air entering from the air inlet column 220 is guided toward the heating element 500 through the arc-shaped guide surface 110, so that the air flows more smoothly through the atomization surface of the heating element 500 after entering the atomization cavity 1021, to prevent formation of vortexes. Specifically, the arc-shaped guide surface 110 is formed in the side of the liquid storage tank 100 facing toward the internal bracket 200.

[0063] Optionally, the arc-shaped guide surface 110 in a circular arc shape. The arc-shaped guide surface 110 faces toward the air inlet column 220 and the heating element 500, so as to guide the air.

[0064] In some embodiments, referring to FIG. 3 and FIG. 5, a connecting channel 1025 is connected between each air inlet channel 1022 and each throttle hole 1024. The cross-sectional size of the connecting channel 1025 is greater than the cross-sectional size of the throttle hole 1024, and the cross-sectional size of the connecting channel 1025 is greater than the cross-sectional size of the air inlet channel 1022. The connecting channel 1025 extends from the air inlet channel 1022 in the second direction Y to a position below the throttle hole 1024, so as to be communicated with the throttle hole 1024.

[0065] In some embodiments, referring to FIG. 4, the atomization device further includes a battery 640 and a control panel610. The battery 640 is electrically connected to the control panel 610. The control panel 610 is separately electrically connected to the heating elements 500 and is electrically connected to a signal input module. The signal input module inputs a control signal to the control panel 610. The control panel 610 controls on or off of electrical connection between the battery 640 and the heating elements 500 based on the control signal.

[0066] The signal input module can be a button 620, a touch display screen, or a voice input module. The control signal inputted through the signal input module includes a control signal for controlling the battery 640 to simultaneously supply power to the heating elements 500, or a control signal for controlling the battery 640 to supply power to some of the heating elements 500. For example, when two heating elements 500 are provided, the control signal may be a control signal for controlling the battery 640 to simultaneously supply power to the two heating elements 500, so that the two heating elements 500 respectively heat and atomize corresponding atomization substrates to generate aerosols, thereby achieving a mixing effect on the aerosols. Or, the control signal may be a control signal for controlling the battery 640 to supply power to one of the heating elements 500. When three or more heating elements 500 are provided, the control signal may be a control signal for controlling the battery 640 to simultaneously supply power to all the heating elements 500, or a control signal for controlling the battery 640 to supply power to one, two, or the like of the heating elements 500. No unique limitation will be imposed here. In this way, a user can select working conditions of the heating elements 500 based on a preference and need of the user, thus meeting usage needs of different users.

[0067] In some embodiments, referring to FIG. 2, the signal input module includes a switching device 611. The switching device 611 is mounted on the control panel 610 and is in communicative connection to the control panel 610. The atomization device further includes a button 620. The button 620 is mounted on the internal bracket 200 and / or the shell 300. The button 620 is exposed from the shell 300. A user can drive the switching device 611 by pressing or toggling the button 620, thereby inputting the control signal.

[0068] In some embodiments, the atomization device is provided with a set of electrodes 630 corresponding to each heating element 500. Each set of electrodes 630 includes two electrodes 630. The two electrodes 630 are mounted on the internal bracket 200. The two electrodes 630 are respectively electrically connected to both the heating element 500 and the control panel 610, thus implementing electrical connection between the control panel 610 and the heating element 500. The control panel 610, the button 620, the electrodes 630, and the battery 640 constitute each control unit 600 of the atomization device.

[0069] In some embodiments, referring to FIG. 6, each electrode 630 is a thimble electrode 630. The thimble electrode 630 is riveted and fixed on the internal bracket 200. The top ends of the two thimble electrodes 630 respectively elastically abut against the two ends of the heating element 500, and the bottom ends of the two thimble electrodes 630 are respectively electrically connected to the control panel 610 through wires. The thimble electrodes 630 and the internal bracket 200 can be riveted for sealing, without gluing or the like, so that the assembling is more flexible.

[0070] Specifically, referring to FIG. 3 and FIG. 6, an annular slot 230 is formed in the side of the internal bracket 200 facing toward the liquid storage tank 100. A seal ring 700 is mounted in the annular slot 230. The annular slot 230 surrounds the outsides of the atomization cavities 1021. The peripheral edge of the bottom of the liquid storage tank 100 is inserted into the annular slot 230 and abuts against the seal ring 700 to achieve sealing between the internal bracket 200 and the liquid storage tank 100 and ensure normal inhalation resistance.

[0071] Specifically, mounting slots communicated to the liquid storage cavities 101 are formed in the bottom of the liquid storage tank 100. The heating elements 500 are sealed and mounted in the mounting slots through silicone sleeves 800. The silicone sleeves 800 are in interference abutment with the inner walls of the mounting slots, and the thimble electrodes 630 abut against the heating elements 500, thereby ensuring the stability of the contact resistance between the thimble electrodes 630 and the heating elements 500.

[0072] In some other embodiments of this application, referring to FIG. 7, each electrode 630 may be a spring contact which is riveted on the internal bracket 200 and is sealed with glue at an opening of the internal bracket 200. One end of the spring contact abuts against the heating element 500, and another end of the spring contact is directly welded to the control panel 610. By using the spring contacts, welding wires can be omitted, and the areas of the spring contacts are relatively large, which is conducive for performing heating, reducing liquid accumulation, and improving the utilization rate of the atomization substrates.

[0073] In some embodiments, referring to FIG. 3 and FIG. 8, the liquid storage tank 100 further has liquid feeding openings 120, vent channels 103, and barrier pieces 130. The liquid feeding openings 120 are communicated to the bottoms of the liquid storage cavities 101. The vent channels 103 have first ports 1031 and second ports. The first ports 1031 are communicated to the liquid storage cavities 101, and the second ports are communicated to the external atmosphere. The barrier pieces 130 are arranged within the liquid storage cavities 101. The barrier pieces 130 are located on the sides of the first ports 1031 facing toward the liquid feeding openings 120, to block air bubbles that flow from the first ports 1031 to the liquid feeding openings 120.

[0074] The liquid feeding openings 120 are communicated to the bottoms of the liquid storage cavities 101. This means that the liquid feeding openings 120 extend outward from the bottoms of the liquid storage cavities 101 and are communicated to the liquid storage cavities 101, so that the atomization substrates in the liquid storage cavities 101 can flow toward the heating elements 500 via the liquid feeding openings 120.

[0075] The first ports 1031 of the vent channels 103 are communicated to the liquid storage cavities 101, and the second ports of the vent channels 103 are communicated to the external atmosphere. The vent channels 103 extend from the first ports 1031 to the second ports. The first ports 1031 of the vent channels103 may be located on the bottom side walls or the circumferential side walls of the liquid storage cavities 101, and the second ports of the vent channels 103 may be directly communicated to the external atmosphere. The second ports of the vent channels 103 may be communicated to the external atmosphere through the atomization cavities 1021.

[0076] The barrier pieces 130 are arranged on the sides of the first ports 1031 facing toward the liquid feeding openings 120. This means that the barrier pieces 130 are arranged on the sides of the first ports 1031 facing toward the liquid feeding openings 120 and are spaced apart from the first ports 1031. The barrier pieces 130 block the first ports 1031, so that the first ports 1031 do not directly face toward the liquid feeding openings 120. That is, the air bubbles generated when external air enters the liquid storage cavities 101 from the first ports 1031 will not flow directly toward the liquid feeding openings 120, but will be blocked by the barrier pieces 130, and slowly float up and disappear.

[0077] In some embodiments, referring to FIG. 8, the first ports 1031, the barrier pieces 130, and the liquid feeding openings 120 are distributed sequentially in the first direction X. In the first direction X, the first projections of the barrier pieces 130 cover the second projections of the first ports 1031.

[0078] The first direction X may be a front-back direction of the atomization device or a left-right direction of the atomization device, or even a direction that forms an angle with the front-back direction of the atomization device. This embodiment uses an example in which the first direction X is the left-right direction of the atomization device for explanation.

[0079] The first ports 1031, the barrier pieces 130, and the liquid feeding openings 120 are distributed sequentially in the first direction X. This means that the barrier pieces 130 are arranged at a position between the distribution directions of the first ports 1031 and the distribution directions of the liquid feeding openings 120, that is, the barrier pieces 130 are arranged on the sides of the first ports 1031 facing toward the liquid feeding openings 120, so as to effectively block the air bubbles formed by the air entering the liquid storage cavities 101 from the first ports 1031.

[0080] The shapes of the second projections of the first ports 1031 in the first direction X may vary depending on the formation positions of the first ports 1031. For example, when the bottom surfaces of the liquid storage cavities 101 are planes, the second projections of the first ports 1031 in the first direction X are lines. For another example, when the bottom surfaces of the liquid storage cavities 101 are surfaces tilting toward the liquid feeding openings 120, the second projections of the first ports 1031 in the first direction X are elliptical or flatly circular. However, regardless of whether the bottom surfaces of the liquid storage cavities 101 are the planes or the tilting surfaces, the first projections of the barrier pieces 130 in the first direction X can cover the second projections of the first ports 1031. This means that the barrier pieces 130 can completely block the first ports 1031 and effectively block the air bubbles formed by the air entering the liquid storage cavities 101 from the first ports 1031.

[0081] In this application, due to the fluidity of the air bubbles, to avoid the air bubbles from bypassing the barrier pieces 130 and flowing toward the liquid feeding ports 120, in some embodiments, referring to FIG. 8, the two opposite ends of each barrier piece 130 in the second direction Y extend at least 0.5 mm relative to the two opposite ends of the first port 1031 in the second direction Y. Every two of the second direction Y, the first direction X, and the longitudinal direction of the atomization device are perpendicular to each other.

[0082] Referring to FIG. 8, assuming that the distance between one end of each barrier piece 130 in the second direction Y and the corresponding end of each first port 1031 in the second direction Y is d1, and the distance between the other end of the barrier piece 130 in the second direction Y and the corresponding end of the first port 1031 in the second direction Y is d2, d1 is greater than or equal to 0.5 mm, and d2 is greater than or equal to 0.5 mm. Specifically, values of d1 and d2 may be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, or even more, as long as the design of the barrier piece 130 does not affect the fluidity of liquid. In this way, the barrier piece 130 can block the air bubbles entering from the first port 1031 in the second direction Y to an extent, to prevent the air bubbles from bypassing the barrier piece 130 in the second direction Y and flowing toward the liquid feeding opening 120.

[0083] In this application, a positional relationship between the first port 1031 and the liquid feeding opening 120 may be set based on an actual situation. The first port 1031 may be located on any side of the liquid feeding opening 120. For example, the first port 1031 may be arranged in front of, behind, to the left, or to the right of the liquid feeding opening 120. In addition, the first port 1031 may be located at the center position of the liquid feeding opening 120 in the second direction Y, and the first port 1031 may alternatively be located at a position, close to the edge in the second direction Y, of the liquid feeding opening 120.

[0084] In an example, referring to FIG. 8, the first port 1031 is located at the position, close to the edge in the second direction Y, of the liquid feeding opening 120, and the size of the liquid feeding opening 120 in the second direction Y is much greater than the size of the first port 1031 in the second direction Y. In this case, d2 may be designed to be greater than d1, so that the barrier piece 130 can effectively block the air bubbles. Meanwhile, the size of d1 is designed to be relatively small to reduce the size of the entire barrier piece 130 in the second direction Y and mitigate the impact of the barrier piece 130 on the fluidity of liquid.

[0085] In another example, the first port 1031 is located at a position, close to the center in the second direction Y, of the liquid feeding opening 120. In this case, the central plane of the barrier piece 130 in the second direction Y may overlap the central plane of the first port 1031 in the second direction Y. That is, the sizes of extension, relative to the two opposite ends of the first port 1031 in the second direction, of the two opposite ends of the barrier piece 130 in the second direction Y are the same.

[0086] In some embodiments, referring to FIG. 8, the cross section of the liquid feeding opening 120 is rectangular, so that the atomization substrates in all directions in the liquid storage cavity 101 can flow uniformly toward the liquid feeding opening 120 for liquid feeding. It can be understood that in other embodiments of this application, the cross section of the liquid feeding opening 120 may be square, circular, elliptical, or in other combined shapes. The combined shape refers to a closed shape formed by sequentially connecting a straight line and / or a curve end to end.

[0087] In one embodiment, referring to FIG. 8, the cross section of the first port 1031 is circular. The inner diameter of the first port 1031 is 0.6 mm to 0.7 mm, so that the air can enter the liquid storage cavity 101 at a uniform speed. It can be understood that in other embodiments of this application, the cross section of the first port 1031 may be square, elliptical, or in other combined shapes. The combined shape refers to a closed shape formed by sequentially connecting a straight line and / or a curve end to end.

[0088] In this application, one or a plurality of vent channels 103 may be provided. When a plurality of vent channels 103 are provided, the first ports 1031 of the vent channels 103 are uniformly distributed around the liquid feeding openings 120, so that the ventilation provided by the vent channels 103 is distributed uniformly.

[0089] In an example, referring to FIG. 8, two vent channels 103 are provided. The first ports 1031 of the two vent channels 103 are located at the two diagonal positions of the liquid feeding opening 120. The first ports 1031 of the two vent channels 103 are in centrosymmetry relative to the center line of the liquid feeding opening 120. In other embodiments, three, four, or more vent channels 103 may be provided.

[0090] In some embodiments, each barrier piece 130 is higher than each first port by at least 0.5 mm in the longitudinal direction of the atomization device. Specifically, the barrier piece 130 may be higher than the first port by 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, or more. Theoretically, it is better if the barrier piece 130 is higher. Certainly, the processing difficulty of the barrier piece 130 needs to be considered. Therefore, it is preferred that the height of the barrier piece 130 is not greater than 3.0 mm.

[0091] In some embodiments, each barrier piece 130 is integrally formed on the inner wall of each liquid storage cavity 101, that is, the barrier piece 130 is integrally connected to the liquid storage tank 100 formed in the liquid storage cavity 101. The barrier piece 130 is integrally formed with the liquid storage tank 100. This not only lowers the processing technology of the barrier piece 130, but also reduces the assembling process of the barrier piece 130, while ensuring the blocking effect of the barrier piece 130. It can be understood that in other embodiments of this application, the barrier piece 130 may be fixed to the inner wall of the liquid storage cavity 101. Specifically, the barrier piece 130 is independently processed and is then fixed to the inner wall of the liquid storage cavity 101 by interference fit, bonding, screw locking, secondary injection molding, or the like.

[0092] In some embodiments, each barrier piece 130 is of a long flat structure, and the size of the barrier piece 130 in the second direction Y is much greater than the size of the barrier piece 130 in the first direction X. This configuration ensures that the blocking ability of the barrier piece 130 in the second direction Y is sufficiently high, and the volume of the barrier piece 130 in the liquid storage cavity 101 is as small as possible.

[0093] In some embodiments, the second port of the vent channel 103 is formed on the silicone sleeve 800, that is, the vent channel 103 is formed on the liquid storage tank 100 and the silicone sleeve 800.

[0094] In some embodiments, referring to FIG. 9, the atomization device further includes an airflow sensor 900 and a seal sleeve 1000. The airflow sensor 900 is electrically connected to the control panel 610, and the seal sleeve 1000 is sleeved outside the airflow sensor 900. The atomization device further has a start airway 104. The start airway 104 is spaced apart from a main airway 102. The main airway 102 includes an air inlet channel 1022, an atomization cavity 1021, and an air outlet channel 1023. The start airway 104 is communicated to the seal sleeve 1000, and the top end of the start airway 104 is communicated to the top end of the main airway 102. When a user inhales the suction nozzle 400, since the start airway 104 is communicated to the main airway 102, the air inside the start airway 104 can be simultaneously driven. The airflow transmits a negative pressure to the airflow sensor 900 through the start airway 104. Under the action of the negative pressure, the airflow sensor 900 starts to work. In this embodiment, the start airway 104 and the main airway 102 are independently separated, and the top end of the start airway 104 and the top end of the main airway 102 are communicated. This can effectively avoid the problem of simultaneous blockage of the main airway 102 and the start airway 104. In addition, even in a case of blockage of the main airway 102, due to the independent arrangement of the start airway 104, the airflow sensor 900 can be smoothly started during inhalation. When the heating elements 500 start heating, the viscosity of the atomization substrates can be reduced to unblock a blocked device.

[0095] Specifically, the liquid storage tank 100 is provided with a connecting port corresponding to the top of the start airway 104. The connecting port achieves communication between the air outlet channel 1023 and the start airway 104.

[0096] In some embodiments, referring to FIG. 9, the seal sleeve 1000 has an accommodating slot 1001 and a negative pressure slot 1002. The airflow sensor 900 is accommodated within the accommodating slot 1001, and the negative pressure slot 1002 is communicated to the accommodating slot 1001. The negative pressure slot 1002 is communicated to the start airway 104, so that the negative pressure can be transmitted to the airflow sensor 900 via the negative pressure slot 1002.

[0097] In some embodiments, referring to FIG. 2, a suction nozzle seal member 1100 is abutted between the suction nozzle 400 and the liquid storage tank 100. The suction nozzle seal member 1100 ensures hermetical communication between the main airway 102 and the start airway 104. Furthermore, the suction nozzle seal member 1100 can ensure that the top of the liquid storage cavity 101 is sealed.

[0098] In some embodiments, referring to FIG. 1, a display screen 1200 is mounted on the surface of the shell 300. The display screen 1200 is electrically connected to the control panel 610. The display screen 1200 is configured to display a working state, a battery level, and the like of the atomization device. The working state of the atomization device includes which heating element 500 being in a working state. In other embodiments of this application, the shell 300 may not be provided with the display screen 1200. Referring to FIG. 10, a display lamp is mounted on the control panel 610. The shell 300 is provided with a through hole 310 in a position corresponding to the display lamp. A usage state of each heating element 500 and a battery level are displayed through the display lamp.

[0099] In this application, the capacity of each liquid storage cavity 101 may be set based on an implementation requirement. For example, the capacity of the liquid storage cavity 101 may be 0.5 ml, 1 ml, or the like.

[0100] While the invention has been illustrated and described in detail in the drawings and foregoing description, such illustration and description are to be considered illustrative or exemplary and not restrictive.

In particular, the present invention covers further embodiments with any combination of features from different embodiments described above and below.

[0033] In addition, the terms “first” and “second” are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or to implicitly indicate the number of technical features indicated. Therefore, a feature limited by “first” or “second” may explicitly or implicitly include one or more of the features. In the descriptions of this application, “a plurality of” means two or more, unless otherwise definitely and specifically limited.

[0034] Referring to FIG. 1 to FIG. 3 together, an atomization device provided in this embodiment of this application is explained now.

[0035] The atomization device includes at least two heating elements 500. Corresponding to each heating element 500, a liquid storage cavity 101, an atomization cavity 1021, and an air inlet channel 1022 are provided. The liquid inlet surface of each heating element 500 faces toward the liquid storage cavity 101, and the atomization surface of the heating element 500 faces toward the atomization cavity 1021. The air inlet channels 1022 are respectively communicated to corresponding atomization cavities 1021. The atomization device further includes an air outlet channel 1023. The atomization cavities 1021 are communicated to the air outlet channel 1023.

[0036] Two, three, four, or more heating elements 500 are provided. Corresponding to each heating element 500, the liquid storage cavity 101, the atomization cavity 1021, and the air inlet channel 1022 are provided, meaning that a quantity of liquid storage cavities 101, a quantity of atomization cavities 1021, and a quantity of air inlet channels 1022 are the same as a quantity of heating elements 500. For ease of description, the heating elements 500 and their corresponding liquid storage cavities 101, atomization cavities 1021, and air inlet channels 1022 can collectively be referred to as atomization units. Thus, the atomization device includes at least two atomization units which operate independently. Aerosols generated by the atomization units are directed from the atomization cavities 1021 to the air outlet channel 1023, are mixed at the air outlet channel 1023, and are finally inhaled by a user via the air outlet channel 1023. For a single atomization unit, an atomization substrate in the liquid storage cavity 101 enters the heating element 500 via the liquid inlet surface of the heating element 500. After being electrified, the heating element 500 generates heat to heat and atomize the atomization substrate to generate aerosols at the atomization surface. The aerosols are generated in the atomization cavity 1021. External air enters the atomization cavity 1021 through the air inlet channel 1022, carries away the aerosols in the atomization cavity 1021, and flows toward the air outlet channel 1023. The aerosols generated in the atomization cavities 1021 are inhaled by the user after being mixed at the air outlet channel 1023.

[0037] According to the atomization device in this embodiment of this application, through the arrangement of the at least two heating elements 500, corresponding to each heating element 500, the liquid storage cavity 101, the atomization cavity 1021, and the air inlet channel 1022 are provided, and the atomization device further includes the air outlet channel 1023. The atomization cavities 1021 are communicated to the air outlet channel 1023, so that aerosols generated in the atomization cavities 1021 can be inhaled by a user after being mixed in the air outlet channel 1023. When an atomization substrate capable of being heated to generate aerosols with different flavors is injected into the liquid storage cavities 101, aerosols with at least two mixed flavors can be obtained in the air outlet channel 1023. When an atomization substrate capable of being heated to generate aerosols with different effects is injected into the liquid storage cavities 101, aerosols with at least two effects can be obtained in the air outlet channel 1023, to meet usage needs of users.

[0038] In some embodiments, the atomization cavities 1021 are arranged around the center line of the air outlet channel 1023 or around an extension line of the center line. Specifically, when the atomization cavities 1021 and the air outlet channel 1023 at least partially overlap in the longitudinal direction of the atomization device, the atomization cavities 1021 are arranged around the center line of the air outlet channel 1023. When the atomization cavities 1021 and the air outlet channel 1023 do not overlap in the longitudinal direction of the atomization device, the atomization cavities 1021 are arranged around the extension line of the center line of the air outlet channel 1023. The longitudinal direction of the atomization device refers to an extension direction perpendicularly extending from one end of the atomization device to another end, namely a height direction of the atomization device when the atomization device is placed vertically. Due to the above configuration of this embodiment, the lengths of paths from the aerosols generated in the atomization cavities 1021 to the air outlet channel 1023 are the same, so that the aerosols generated in the air outlet channel 1021 can be mixed uniformly in the air outlet channel 1023. It can be understood that in other embodiments of this application, the atomization cavities 1021 may be arranged sequentially in a direction, and the air outlet channel 1023 is arranged on the same sides of the atomization cavities 1021, without imposing a unique limitation herein.

[0039] In some embodiments, referring to FIG. 2, corresponding liquid storage cavities 101, heating elements 500, atomization cavities 1021, and air inlet channels 1022 are distributed in the longitudinal direction of the atomization device. The liquid storage cavities 101 are distributed in the transverse direction of the atomization device.

[0040] The corresponding liquid storage cavities 101, heating elements 500, atomization cavities 1021, and air inlet channels 1022 are distributed in the longitudinal direction of the atomization device. This means that the liquid storage cavities 101, the heating elements 500, the atomization cavities 1021, and the air inlet channels 1022 are distributed in the longitudinal direction of the atomization device.

[0041] The liquid storage cavities 101 are distributed in the transverse direction of the atomization device. The transverse direction of the atomization device refers to a direction perpendicular to the longitudinal direction of the atomization device. When the liquid storage cavities 101 are distributed in the transverse direction of the atomization device, the heating elements 500 are also distributed in the transverse direction of the atomization device, the atomization cavities 1021 are also distributed in the transverse direction of the atomization device, and the air inlet channels 1022 are also distributed in the transverse direction of the atomization device. The above configuration implements a compact and orderly structural layout of the atomization units and ensures no mutual interference.

[0042] In some embodiments, referring to FIG. 2, the liquid storage cavity 101, the heating element 500, the atomization cavity 1021, and the air inlet channel 1022 in the same atomization unit are arranged sequentially in the longitudinal direction of the atomization device. The atomization substrate in the liquid storage cavity 101 can be directed to the heating element 500 under action of gravity. External atmosphere in the air inlet channel 1022 can upward enter the atomization cavity 1021 to carry the aerosols inside the atomization cavity 1021, and the external atmosphere carrying the aerosols upward enter the air outlet channel 1023 for user inhalation.

[0043] In some embodiments, as shown in FIG. 2, the atomization units are arranged around the air outlet channel 1023. That is, the atomization units are distributed in the circumferential direction of the atomization device. It can be understood that in other embodiments of this application, the atomization units may be arranged sequentially in the transverse direction of the atomization device. The air outlet channel 1023 is arranged on the same sides of the atomization units, without imposing a unique limitation herein.

[0044] In some specific embodiments, referring to FIG. 2 to FIG. 5, the atomization device includes two atomization units that are spaced apart from each other in the transverse direction of the atomization device. Specifically, the two atomization units are spaced apart from each other in the transverse direction in which the atomization device has a larger size. For example, the size of the atomization device in a first direction X is greater than the size of the atomization device in a second direction Y. The two atomization units are distributed in the first direction X. In each atomization unit, the liquid storage cavity 101, the heating element 500, the atomization cavity 1021, and the air inlet channel 1022 are arranged sequentially in the longitudinal direction of the atomization device. The air outlet channel 1023 extends in the longitudinal direction of the atomization device and is located at the center position between the two atomization units. The air outlet channel 1023 corresponds to the liquid storage cavity 101 and the heating element 500 in the longitudinal direction of the atomization device.

[0045] Specifically, both the liquid inlet surface and the atomization surface of the heating element 500 are perpendicular to the longitudinal direction of the atomization device. This means that the heating element 500 is arranged transversely to reduce a longitudinal space occupied by the heating element 500 in the atomization device.

[0046] In some embodiments, referring to FIG. 2 to FIG. 4, an isolation portion 210 for isolating the atomization cavities 1021 from each other is arranged between the atomization cavities 1021. The arrangement of the isolation portion 210 can prevent formation of vortexes when the aerosols in the atomization cavities 1021 are mixed from affecting the stability of an airflow.

[0047] In some embodiments, referring to FIG. 2, the isolation portion 210 at least partially extends into the air outlet channel 1023, and partitions an inlet of the air outlet channel 1023 for corresponding communication with the atomization cavities 1021. Specifically, the isolation portion 210 partitions the inlet of the air outlet channel 1023 into a plurality of inlet portions 10231 which are respectively configured to respectively introduce the aerosols in the atomization cavities 1021 into the air outlet channel 1023. In this embodiment, through the design in which the isolation portion 210 extends into the air outlet channel 1023, the aerosols in the atomization cavities 1021 will not be mixed before entering the air outlet channel 1023, thus avoiding the formation of the vortex and ensuring the stability of the airflow.

[0048] In some embodiments, referring to FIG. 2 to FIG. 4, the bottom of the isolation portion 210 has a first arc-shaped surface 211 configured to guide airflows in the atomization cavities 1021 to the inlet portions 10231, to ensure smooth switching of the airflows in the atomization cavities 1021 from the transverse direction to the longitudinal direction.

[0049] In some embodiments, referring to FIG. 2, the cross-sectional area of the inlet of the air outlet channel 1023 gradually decreases from bottom to top. The inner circumferential surface of the inlet of the air outlet channel 1023 is an arc-shaped surface or a curved surface, so that the airflows in the atomization cavities 1021 smoothly enter the air outlet channel 1023. This can ensure that the airflows are smooth, functions are stable in a use process, and negative phenomena such as blocked inhalation are avoided.

[0050] In some embodiments, the atomization device includes a suction nozzle 400, a liquid storage tank 100, an internal bracket 200, and a shell 300. The internal bracket 200 and the liquid storage tank 100 jointly enclose the atomization cavities 1021. The shell 300 is sleeved outside the internal bracket 200. The suction nozzle 400 is sleeved outside the liquid storage tank 100. The suction nozzle 400 is connected to the shell 300. The liquid storage cavities 101 are formed in the liquid storage tank 100. The air outlet channel 1023 penetrates through the liquid storage tank 100 and the suction nozzle 400. The air inlet channels 1022 are formed in the side surface of the internal bracket 200 facing toward the shell 300. By forming the air inlet channels 1022 on the side surface of the internal bracket 200 facing toward the shell 300, it is convenient to control a flow velocity of air and leave space for other structures. For example, the air inlet channels 1022 can be separated from a control unit 600, to facilitate air intake control, facilitate control of airflow noises, and also prevent liquid leakage to the control unit 600.

[0051] In some embodiments, referring to FIG. 5, the air inlet channels 1022 are formed on the side surface of the internal bracket 200 in the second direction Y. The air inlet channels 1022 are distributed in a spacing manner in the first direction X. A mounting cavity is formed on the other side surface of the internal bracket 200 in the second direction Y and is configured to mount the control unit 600, thereby isolating the air inlet channels 1022 from the control unit 600.

[0052] In some embodiments, referring to FIG. 5 and FIG. 9, the atomization device further includes one air inlet hole 1026 communicated to external atmosphere. One end of each air inlet channel 1022 is communicated to the air inlet hole 1026, and another end of each air inlet channel 1022 is communicated to each atomization cavity 1021. After the external atmosphere enters the atomization device via the air inlet hole 1026, the external atmosphere enters the corresponding atomization cavities 1021 from the air inlet channels 1022 to carry the aerosols into the air outlet channel 1023, and is inhaled by a user after being mixed in the air outlet channel 1023.

[0053] In some embodiments, the air inlet hole 1026 is formed in the center position of the side, facing away from the suction nozzle 400, of the shell 300. The air inlet channels 1022 are symmetrically distributed relative to the center line of the air inlet hole 1026. It can be understood that in other embodiments of this application, the atomization device may further include a plurality of air inlet holes 1026 communicated to the external atmosphere. One end of each air inlet channel 1022 is communicated to each air inlet hole 1026, and another end of each air inlet channel 1022 is communicated to each atomization cavity 1021. This means that the air intake of each atomization unit is independently set, and no unique limitation is imposed here.

[0054] In some embodiments, referring to FIG. 5, the air inlet channels 1022 are formed in the internal bracket 200. Specifically, the internal bracket 200 is inwards recessed in the second direction Y to form the air inlet channels 1022. The air inlet channels 1022 converge in the middle portion of the side, facing away from the liquid storage tank 100, of the internal bracket 200 to form a convergence port 1027, and are communicated to the air inlet holes 1026 of the shell 300. The second direction Y is perpendicular to the first direction X. The first direction X can be referred to as a left-right direction or width direction of the atomization device, and the second direction Y can be referred to as a front-back direction or thickness direction of the atomization device.

[0055] In some embodiments, the liquid storage tank 100 and the internal bracket 200 are distributed in the longitudinal direction of the atomization device and are connected to each other in a plugging manner. The internal bracket 200 is clamped to the shell 300, and the suction nozzle 400 and the shell 300 abut against each other in the longitudinal direction of the atomization device and are clamped to each other.

[0056] In some embodiments, referring to FIG. 2 and FIG. 4, one side of the internal bracket 200 facing toward the liquid storage tank 100 is recessed inward to form a groove. The middle position of the groove is directly opposite to the air outlet channel 1023 in the longitudinal direction, and the isolation portion 210 extends in the longitudinal direction from the bottom of the middle position of the groove into the air outlet channel 1023. The cross-sectional area of the bottom of the isolation portion 210 gradually decreases from bottom to top to form each first arc-shaped surface 211 on the surface.

[0057] In some embodiments, referring to FIG. 3, a throttle hole 1024 is formed in the bottom of each atomization cavity 1021, and communicates the atomization cavity 1021 to each air inlet channel 1022. Through the arrangement of the throttle hole 1024, an air flow rate can be adjusted to implement suction resistance control on the atomization unit, to meet inhalation needs of users.

[0058] In some embodiments, referring to FIG. 3 and FIG. 4, an air inlet column 220 is arranged in the atomization cavity 1021 and protrudes a preset height from the bottom of the atomization cavity 220. The bottom end of the air inlet column 220 is communicated to the throttle hole 1024. An airflow enters the air inlet column 220 after passing through the throttle hole 1024, which can ensure the direction of the airflow. Meanwhile, intake air is conveyed into the atomization cavity 1021 at the preset height through the air inlet column 220, thereby mitigating the problem that condensate in the atomization cavity 1021 flows into the air inlet channel 1022 and the mitigating the problem that the air inlet channel 1022 is blocked.

[0059] In some embodiments, referring to FIG. 3, the air inlet column 220 is roughly in a horn shape, so that the air at the outlet of the air inlet column 220 can be quickly dispersed to the surrounding region, to prevent the air from being condensed at the top.

[0060] In some embodiments, the longitudinal distance from the top end surface of the air inlet column 220 to the heating element 500 is greater than or equal to 0.5 mm, for example, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2.0 mm, or the like. In this embodiment, the longitudinal distance from the top end surface of the air inlet column 220 to the heating element 500 is limited to prevent air condensation of the air entering from the air inlet column 220 due to insufficient dispersion caused by the small distance between the air inlet column 220 and the heating element 500.

[0061] In some embodiments, the size of the air inlet column 220 and the size of the heating element 500 in the transverse direction of the atomization device are greater than 0.5 mm, for example, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, or 2.0 mm. In this way, the air in the air inlet column 220 can be in full contact with the aerosols to bring away the aerosols.

[0062] In some embodiments, referring to FIG. 3, an arc-shaped guide surface 110 is formed at a position, corresponding to the position of the outlet of the air inlet column 220, on the inner wall of the top side of the atomization cavity 1021. The air entering from the air inlet column 220 is guided toward the heating element 500 through the arc-shaped guide surface 110, so that the air flows more smoothly through the atomization surface of the heating element 500 after entering the atomization cavity 1021, to prevent formation of vortexes. Specifically, the arc-shaped guide surface 110 is formed in the side of the liquid storage tank 100 facing toward the internal bracket 200.

[0063] Optionally, the arc-shaped guide surface 110 in a circular arc shape. The arc-shaped guide surface 110 faces toward the air inlet column 220 and the heating element 500, so as to guide the air.

[0064] In some embodiments, referring to FIG. 3 and FIG. 5, a connecting channel 1025 is connected between each air inlet channel 1022 and each throttle hole 1024. The cross-sectional size of the connecting channel 1025 is greater than the cross-sectional size of the throttle hole 1024, and the cross-sectional size of the connecting channel 1025 is greater than the cross-sectional size of the air inlet channel 1022. The connecting channel 1025 extends from the air inlet channel 1022 in the second direction Y to a position below the throttle hole 1024, so as to be communicated with the throttle hole 1024.

[0065] In some embodiments, referring to FIG. 4, the atomization device further includes a battery 640 and a control panel610. The battery 640 is electrically connected to the control panel 610. The control panel 610 is separately electrically connected to the heating elements 500 and is electrically connected to a signal input module. The signal input module inputs a control signal to the control panel 610. The control panel 610 controls on or off of electrical connection between the battery 640 and the heating elements 500 based on the control signal.

[0066] The signal input module can be a button 620, a touch display screen, or a voice input module. The control signal inputted through the signal input module includes a control signal for controlling the battery 640 to simultaneously supply power to the heating elements 500, or a control signal for controlling the battery 640 to supply power to some of the heating elements 500. For example, when two heating elements 500 are provided, the control signal may be a control signal for controlling the battery 640 to simultaneously supply power to the two heating elements 500, so that the two heating elements 500 respectively heat and atomize corresponding atomization substrates to generate aerosols, thereby achieving a mixing effect on the aerosols. Or, the control signal may be a control signal for controlling the battery 640 to supply power to one of the heating elements 500. When three or more heating elements 500 are provided, the control signal may be a control signal for controlling the battery 640 to simultaneously supply power to all the heating elements 500, or a control signal for controlling the battery 640 to supply power to one, two, or the like of the heating elements 500. No unique limitation will be imposed here. In this way, a user can select working conditions of the heating elements 500 based on a preference and need of the user, thus meeting usage needs of different users.

[0067] In some embodiments, referring to FIG. 2, the signal input module includes a switching device 611. The switching device 611 is mounted on the control panel 610 and is in communicative connection to the control panel 610. The atomization device further includes a button 620. The button 620 is mounted on the internal bracket 200 and / or the shell 300. The button 620 is exposed from the shell 300. A user can drive the switching device 611 by pressing or toggling the button 620, thereby inputting the control signal.

[0068] In some embodiments, the atomization device is provided with a set of electrodes 630 corresponding to each heating element 500. Each set of electrodes 630 includes two electrodes 630. The two electrodes 630 are mounted on the internal bracket 200. The two electrodes 630 are respectively electrically connected to both the heating element 500 and the control panel 610, thus implementing electrical connection between the control panel 610 and the heating element 500. The control panel 610, the button 620, the electrodes 630, and the battery 640 constitute each control unit 600 of the atomization device.

[0069] In some embodiments, referring to FIG. 6, each electrode 630 is a thimble electrode 630. The thimble electrode 630 is riveted and fixed on the internal bracket 200. The top ends of the two thimble electrodes 630 respectively elastically abut against the two ends of the heating element 500, and the bottom ends of the two thimble electrodes 630 are respectively electrically connected to the control panel 610 through wires. The thimble electrodes 630 and the internal bracket 200 can be riveted for sealing, without gluing or the like, so that the assembling is more flexible.

[0070] Specifically, referring to FIG. 3 and FIG. 6, an annular slot 230 is formed in the side of the internal bracket 200 facing toward the liquid storage tank 100. A seal ring 700 is mounted in the annular slot 230. The annular slot 230 surrounds the outsides of the atomization cavities 1021. The peripheral edge of the bottom of the liquid storage tank 100 is inserted into the annular slot 230 and abuts against the seal ring 700 to achieve sealing between the internal bracket 200 and the liquid storage tank 100 and ensure normal inhalation resistance.

[0071] Specifically, mounting slots communicated to the liquid storage cavities 101 are formed in the bottom of the liquid storage tank 100. The heating elements 500 are sealed and mounted in the mounting slots through silicone sleeves 800. The silicone sleeves 800 are in interference abutment with the inner walls of the mounting slots, and the thimble electrodes 630 abut against the heating elements 500, thereby ensuring the stability of the contact resistance between the thimble electrodes 630 and the heating elements 500.

[0072] In some other embodiments of this application, referring to FIG. 7, each electrode 630 may be a spring contact which is riveted on the internal bracket 200 and is sealed with glue at an opening of the internal bracket 200. One end of the spring contact abuts against the heating element 500, and another end of the spring contact is directly welded to the control panel 610. By using the spring contacts, welding wires can be omitted, and the areas of the spring contacts are relatively large, which is conducive for performing heating, reducing liquid accumulation, and improving the utilization rate of the atomization substrates.

[0073] In some embodiments, referring to FIG. 3 and FIG. 8, the liquid storage tank 100 further has liquid feeding openings 120, vent channels 103, and barrier pieces 130. The liquid feeding openings 120 are communicated to the bottoms of the liquid storage cavities 101. The vent channels 103 have first ports 1031 and second ports. The first ports 1031 are communicated to the liquid storage cavities 101, and the second ports are communicated to the external atmosphere. The barrier pieces 130 are arranged within the liquid storage cavities 101. The barrier pieces 130 are located on the sides of the first ports 1031 facing toward the liquid feeding openings 120, to block air bubbles that flow from the first ports 1031 to the liquid feeding openings 120.

[0074] The liquid feeding openings 120 are communicated to the bottoms of the liquid storage cavities 101. This means that the liquid feeding openings 120 extend outward from the bottoms of the liquid storage cavities 101 and are communicated to the liquid storage cavities 101, so that the atomization substrates in the liquid storage cavities 101 can flow toward the heating elements 500 via the liquid feeding openings 120.

[0075] The first ports 1031 of the vent channels 103 are communicated to the liquid storage cavities 101, and the second ports of the vent channels 103 are communicated to the external atmosphere. The vent channels 103 extend from the first ports 1031 to the second ports. The first ports 1031 of the vent channels103 may be located on the bottom side walls or the circumferential side walls of the liquid storage cavities 101, and the second ports of the vent channels 103 may be directly communicated to the external atmosphere. The second ports of the vent channels 103 may be communicated to the external atmosphere through the atomization cavities 1021.

[0076] The barrier pieces 130 are arranged on the sides of the first ports 1031 facing toward the liquid feeding openings 120. This means that the barrier pieces 130 are arranged on the sides of the first ports 1031 facing toward the liquid feeding openings 120 and are spaced apart from the first ports 1031. The barrier pieces 130 block the first ports 1031, so that the first ports 1031 do not directly face toward the liquid feeding openings 120. That is, the air bubbles generated when external air enters the liquid storage cavities 101 from the first ports 1031 will not flow directly toward the liquid feeding openings 120, but will be blocked by the barrier pieces 130, and slowly float up and disappear.

[0077] In some embodiments, referring to FIG. 8, the first ports 1031, the barrier pieces 130, and the liquid feeding openings 120 are distributed sequentially in the first direction X. In the first direction X, the first projections of the barrier pieces 130 cover the second projections of the first ports 1031.

[0078] The first direction X may be a front-back direction of the atomization device or a left-right direction of the atomization device, or even a direction that forms an angle with the front-back direction of the atomization device. This embodiment uses an example in which the first direction X is the left-right direction of the atomization device for explanation.

[0079] The first ports 1031, the barrier pieces 130, and the liquid feeding openings 120 are distributed sequentially in the first direction X. This means that the barrier pieces 130 are arranged at a position between the distribution directions of the first ports 1031 and the distribution directions of the liquid feeding openings 120, that is, the barrier pieces 130 are arranged on the sides of the first ports 1031 facing toward the liquid feeding openings 120, so as to effectively block the air bubbles formed by the air entering the liquid storage cavities 101 from the first ports 1031.

[0080] The shapes of the second projections of the first ports 1031 in the first direction X may vary depending on the formation positions of the first ports 1031. For example, when the bottom surfaces of the liquid storage cavities 101 are planes, the second projections of the first ports 1031 in the first direction X are lines. For another example, when the bottom surfaces of the liquid storage cavities 101 are surfaces tilting toward the liquid feeding openings 120, the second projections of the first ports 1031 in the first direction X are elliptical or flatly circular. However, regardless of whether the bottom surfaces of the liquid storage cavities 101 are the planes or the tilting surfaces, the first projections of the barrier pieces 130 in the first direction X can cover the second projections of the first ports 1031. This means that the barrier pieces 130 can completely block the first ports 1031 and effectively block the air bubbles formed by the air entering the liquid storage cavities 101 from the first ports 1031.

[0081] In this application, due to the fluidity of the air bubbles, to avoid the air bubbles from bypassing the barrier pieces 130 and flowing toward the liquid feeding ports 120, in some embodiments, referring to FIG. 8, the two opposite ends of each barrier piece 130 in the second direction Y extend at least 0.5 mm relative to the two opposite ends of the first port 1031 in the second direction Y. Every two of the second direction Y, the first direction X, and the longitudinal direction of the atomization device are perpendicular to each other.

[0082] Referring to FIG. 8, assuming that the distance between one end of each barrier piece 130 in the second direction Y and the corresponding end of each first port 1031 in the second direction Y is d1, and the distance between the other end of the barrier piece 130 in the second direction Y and the corresponding end of the first port 1031 in the second direction Y is d2, d1 is greater than or equal to 0.5 mm, and d2 is greater than or equal to 0.5 mm. Specifically, values of d1 and d2 may be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, or even more, as long as the design of the barrier piece 130 does not affect the fluidity of liquid. In this way, the barrier piece 130 can block the air bubbles entering from the first port 1031 in the second direction Y to an extent, to prevent the air bubbles from bypassing the barrier piece 130 in the second direction Y and flowing toward the liquid feeding opening 120.

[0083] In this application, a positional relationship between the first port 1031 and the liquid feeding opening 120 may be set based on an actual situation. The first port 1031 may be located on any side of the liquid feeding opening 120. For example, the first port 1031 may be arranged in front of, behind, to the left, or to the right of the liquid feeding opening 120. In addition, the first port 1031 may be located at the center position of the liquid feeding opening 120 in the second direction Y, and the first port 1031 may alternatively be located at a position, close to the edge in the second direction Y, of the liquid feeding opening 120.

[0084] In an example, referring to FIG. 8, the first port 1031 is located at the position, close to the edge in the second direction Y, of the liquid feeding opening 120, and the size of the liquid feeding opening 120 in the second direction Y is much greater than the size of the first port 1031 in the second direction Y. In this case, d2 may be designed to be greater than d1, so that the barrier piece 130 can effectively block the air bubbles. Meanwhile, the size of d1 is designed to be relatively small to reduce the size of the entire barrier piece 130 in the second direction Y and mitigate the impact of the barrier piece 130 on the fluidity of liquid.

[0085] In another example, the first port 1031 is located at a position, close to the center in the second direction Y, of the liquid feeding opening 120. In this case, the central plane of the barrier piece 130 in the second direction Y may overlap the central plane of the first port 1031 in the second direction Y. That is, the sizes of extension, relative to the two opposite ends of the first port 1031 in the second direction, of the two opposite ends of the barrier piece 130 in the second direction Y are the same.

[0086] In some embodiments, referring to FIG. 8, the cross section of the liquid feeding opening 120 is rectangular, so that the atomization substrates in all directions in the liquid storage cavity 101 can flow uniformly toward the liquid feeding opening 120 for liquid feeding. It can be understood that in other embodiments of this application, the cross section of the liquid feeding opening 120 may be square, circular, elliptical, or in other combined shapes. The combined shape refers to a closed shape formed by sequentially connecting a straight line and / or a curve end to end.

[0087] In one embodiment, referring to FIG. 8, the cross section of the first port 1031 is circular. The inner diameter of the first port 1031 is 0.6 mm to 0.7 mm, so that the air can enter the liquid storage cavity 101 at a uniform speed. It can be understood that in other embodiments of this application, the cross section of the first port 1031 may be square, elliptical, or in other combined shapes. The combined shape refers to a closed shape formed by sequentially connecting a straight line and / or a curve end to end.

[0088] In this application, one or a plurality of vent channels 103 may be provided. When a plurality of vent channels 103 are provided, the first ports 1031 of the vent channels 103 are uniformly distributed around the liquid feeding openings 120, so that the ventilation provided by the vent channels 103 is distributed uniformly.

[0089] In an example, referring to FIG. 8, two vent channels 103 are provided. The first ports 1031 of the two vent channels 103 are located at the two diagonal positions of the liquid feeding opening 120. The first ports 1031 of the two vent channels 103 are in centrosymmetry relative to the center line of the liquid feeding opening 120. In other embodiments, three, four, or more vent channels 103 may be provided.

[0090] In some embodiments, each barrier piece 130 is higher than each first port by at least 0.5 mm in the longitudinal direction of the atomization device. Specifically, the barrier piece 130 may be higher than the first port by 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, or more. Theoretically, it is better if the barrier piece 130 is higher. Certainly, the processing difficulty of the barrier piece 130 needs to be considered. Therefore, it is preferred that the height of the barrier piece 130 is not greater than 3.0 mm.

[0091] In some embodiments, each barrier piece 130 is integrally formed on the inner wall of each liquid storage cavity 101, that is, the barrier piece 130 is integrally connected to the liquid storage tank 100 formed in the liquid storage cavity 101. The barrier piece 130 is integrally formed with the liquid storage tank 100. This not only lowers the processing technology of the barrier piece 130, but also reduces the assembling process of the barrier piece 130, while ensuring the blocking effect of the barrier piece 130. It can be understood that in other embodiments of this application, the barrier piece 130 may be fixed to the inner wall of the liquid storage cavity 101. Specifically, the barrier piece 130 is independently processed and is then fixed to the inner wall of the liquid storage cavity 101 by interference fit, bonding, screw locking, secondary injection molding, or the like.

[0092] In some embodiments, each barrier piece 130 is of a long flat structure, and the size of the barrier piece 130 in the second direction Y is much greater than the size of the barrier piece 130 in the first direction X. This configuration ensures that the blocking ability of the barrier piece 130 in the second direction Y is sufficiently high, and the volume of the barrier piece 130 in the liquid storage cavity 101 is as small as possible.

[0093] In some embodiments, the second port of the vent channel 103 is formed on the silicone sleeve 800, that is, the vent channel 103 is formed on the liquid storage tank 100 and the silicone sleeve 800.

[0094] In some embodiments, referring to FIG. 9, the atomization device further includes an airflow sensor 900 and a seal sleeve 1000. The airflow sensor 900 is electrically connected to the control panel 610, and the seal sleeve 1000 is sleeved outside the airflow sensor 900. The atomization device further has a start airway 104. The start airway 104 is spaced apart from a main airway 102. The main airway 102 includes an air inlet channel 1022, an atomization cavity 1021, and an air outlet channel 1023. The start airway 104 is communicated to the seal sleeve 1000, and the top end of the start airway 104 is communicated to the top end of the main airway 102. When a user inhales the suction nozzle 400, since the start airway 104 is communicated to the main airway 102, the air inside the start airway 104 can be simultaneously driven. The airflow transmits a negative pressure to the airflow sensor 900 through the start airway 104. Under the action of the negative pressure, the airflow sensor 900 starts to work. In this embodiment, the start airway 104 and the main airway 102 are independently separated, and the top end of the start airway 104 and the top end of the main airway 102 are communicated. This can effectively avoid the problem of simultaneous blockage of the main airway 102 and the start airway 104. In addition, even in a case of blockage of the main airway 102, due to the independent arrangement of the start airway 104, the airflow sensor 900 can be smoothly started during inhalation. When the heating elements 500 start heating, the viscosity of the atomization substrates can be reduced to unblock a blocked device.

[0095] Specifically, the liquid storage tank 100 is provided with a connecting port corresponding to the top of the start airway 104. The connecting port achieves communication between the air outlet channel 1023 and the start airway 104.

[0096] In some embodiments, referring to FIG. 9, the seal sleeve 1000 has an accommodating slot 1001 and a negative pressure slot 1002. The airflow sensor 900 is accommodated within the accommodating slot 1001, and the negative pressure slot 1002 is communicated to the accommodating slot 1001. The negative pressure slot 1002 is communicated to the start airway 104, so that the negative pressure can be transmitted to the airflow sensor 900 via the negative pressure slot 1002.

[0097] In some embodiments, referring to FIG. 2, a suction nozzle seal member 1100 is abutted between the suction nozzle 400 and the liquid storage tank 100. The suction nozzle seal member 1100 ensures hermetical communication between the main airway 102 and the start airway 104. Furthermore, the suction nozzle seal member 1100 can ensure that the top of the liquid storage cavity 101 is sealed.

[0098] In some embodiments, referring to FIG. 1, a display screen 1200 is mounted on the surface of the shell 300. The display screen 1200 is electrically connected to the control panel 610. The display screen 1200 is configured to display a working state, a battery level, and the like of the atomization device. The working state of the atomization device includes which heating element 500 being in a working state. In other embodiments of this application, the shell 300 may not be provided with the display screen 1200. Referring to FIG. 10, a display lamp is mounted on the control panel 610. The shell 300 is provided with a through hole 310 in a position corresponding to the display lamp. A usage state of each heating element 500 and a battery level are displayed through the display lamp.

[0099] In this application, the capacity of each liquid storage cavity 101 may be set based on an implementation requirement. For example, the capacity of the liquid storage cavity 101 may be 0.5 ml, 1 ml, or the like.
