[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0033] Please refer to the following: Figures 1 to 3 The atomizing device provided in the embodiments of this application will now be described.

[0034] The atomizing device includes at least two heating elements 500. Each heating element 500 is provided with a liquid storage chamber 101, an atomizing chamber 1021, and an air inlet channel 1022. The liquid inlet surface of the heating element 500 faces the liquid storage chamber 101, and the atomizing surface of the heating element 500 faces the atomizing chamber 1021. Each air inlet channel 1022 is connected to the corresponding atomizing chamber 1021. The atomizing device also includes an air outlet channel 1023, and each atomizing chamber 1021 is connected to the air outlet channel 1023.

[0035] The number of heating elements 500 can be two, three, four, or more. Each heating element 500 is provided with a liquid storage chamber 101, an atomizing chamber 1021, and an air inlet channel 1022; that is, the number of liquid storage chambers 101, atomizing chambers 1021, and air inlet channels 1022 is the same as the number of heating elements 500. For ease of description, the heating element 500 and its corresponding liquid storage chamber 101, atomizing chamber 1021, and air inlet channel 1022 can be collectively referred to as an atomizing unit. Therefore, the atomizing device includes at least two atomizing units, each of which operates independently. The aerosol generated by each atomizing unit is guided by its respective atomizing chamber 1021 to the air outlet channel 1023, where it mixes and is finally inhaled by the user through the air outlet channel 1023. For a single atomizing unit, the atomizing medium in the storage chamber 101 enters the heating element 500 through the liquid inlet surface of the heating element 500. After the heating element 500 is energized, it heats up to atomize the atomizing medium and form an aerosol at the atomizing surface. The aerosol is formed in the atomizing chamber 1021. External air enters the atomizing chamber 1021 through the air inlet channel 1022 to carry away the aerosol in the atomizing chamber 1021 and flow to the air outlet channel 1023. The aerosols generated in each atomizing chamber 1021 are mixed in the air outlet channel 1023 and then inhaled by the user.

[0036] The atomizing device in this embodiment of the application is provided with at least two heating elements 500. Each heating element 500 is provided with a liquid storage chamber 101, an atomizing chamber 1021, and an air inlet channel 1022. The atomizing device also includes an air outlet channel 1023. Each atomizing chamber 1021 is connected to the air outlet channel 1023, so that the aerosol generated in each atomizing chamber 1021 can be mixed in the air outlet channel 1023 and then inhaled by the user. When an atomizing medium that can be heated to produce aerosols with different flavors is injected into each liquid storage chamber 101, at least two mixed flavors of aerosol can be obtained in the air outlet channel 1023. When an atomizing medium that can be heated to produce aerosols with different effects is injected into each liquid storage chamber 101, at least two effects of aerosol can be obtained in the air outlet channel 1023, so as to meet the user's needs.

[0037] In some embodiments, each atomizing chamber 1021 is arranged around the centerline of the air outlet channel 1023 or around an extension of the centerline. Specifically, when the atomizing chamber 1021 and the air outlet channel 1023 at least partially overlap along the longitudinal direction of the atomizing device, each atomizing chamber 1021 is arranged around the centerline of the air outlet channel 1023. When the atomizing chamber 1021 and the air outlet channel 1023 do not overlap along the longitudinal direction of the atomizing device, each atomizing chamber 1021 is arranged around an extension of the centerline of the air outlet channel 1023. The longitudinal direction of the atomizing device refers to the direction extending vertically from one end of the atomizing device to the other, that is, the height direction of the atomizing device when it is placed vertically. The above arrangement in this embodiment ensures that the path length from the aerosol generated in each atomizing chamber 1021 to the air outlet channel 1023 is the same, allowing the aerosol generated in each atomizing chamber 1021 to mix uniformly in the air outlet channel 1023. It is understood that in other embodiments of this application, the atomizing chambers 1021 may be distributed sequentially along one direction, and the air outlet channel 1023 may be located on the same side of each atomizing chamber 1021. This is not a unique limitation.

[0038] In some embodiments, please refer to Figure 2 The corresponding liquid storage chamber 101, heating element 500, atomizing chamber 1021 and air intake channel 1022 are distributed along the longitudinal direction of the atomizing device; each liquid storage chamber 101 is distributed along the transverse direction of the atomizing device.

[0039] The corresponding liquid storage chamber 101, heating element 500, atomizing chamber 1021 and air intake channel 1022 are distributed along the longitudinal direction of the atomizing device, which means that the liquid storage chamber 101, heating element 500, atomizing chamber 1021 and air intake channel 1022 in the same atomizing unit are distributed along the longitudinal direction of the atomizing device.

[0040] Each liquid storage chamber 101 is distributed laterally along the atomizing device, where "lateral" refers to the direction perpendicular to the longitudinal direction of the atomizing device. When each liquid storage chamber 101 is distributed laterally along the atomizing device, each heating element 500, each atomizing chamber 1021, and each air intake channel 1022 are also distributed laterally along the atomizing device. This arrangement not only makes the structural layout of each atomizing unit compact and neat, but also prevents mutual interference.

[0041] In some embodiments, please refer to Figure 2The liquid storage chamber 101, heating element 500, atomizing chamber 1021 and air inlet channel 1022 in the same atomizing unit are distributed in sequence along the longitudinal direction of the atomizing device. The atomizing medium in the liquid storage chamber 101 can be guided to the heating element 500 under the action of gravity. The external atmosphere in the air inlet channel 1022 can enter the atomizing chamber 1021 upward to carry the aerosol in the atomizing chamber 1021, and carry the aerosol upward into the air outlet channel 1023 for the user to inhale.

[0042] In some embodiments, please refer to Figure 2 Each atomizing unit is arranged around the air outlet channel 1023. That is, the atomizing units are distributed along the circumference of the atomizing device. It can be understood that in other embodiments of this application, the atomizing units may also be distributed sequentially at intervals along the transverse direction of the atomizing device, with the air outlet channel 1023 located on the same side of each atomizing unit; this is not a unique limitation.

[0043] For some specific embodiments, please refer to Figures 2 to 5 The atomizing device includes two atomizing units, which are spaced laterally along the atomizing device. Specifically, the two atomizing units are spaced laterally with a relatively large dimension of the atomizing device; for example, the dimension of the atomizing device along the first direction X is larger than the dimension along the second direction Y. The two atomizing units are distributed along the first direction X. In each atomizing unit, the liquid storage chamber 101, the heating element 500, the atomizing chamber 1021, and the air inlet channel 1022 are sequentially distributed along the longitudinal direction of the atomizing device. The air outlet channel 1023 extends along the longitudinal direction of the atomizing device and is located at the center of the two atomizing units. The air outlet channel 1023 corresponds to the liquid storage chamber 101 and the heating element 500 along the longitudinal direction of the atomizing device.

[0044] Specifically, the liquid inlet surface and atomizing surface of the heating element 500 are both perpendicular to the longitudinal direction of the atomizing device, that is, the heating element 500 is arranged laterally to reduce the space occupied by the heating element 500 along the longitudinal direction of the atomizing device.

[0045] In some embodiments, please refer to Figures 2 to 4 An isolation section 210 is provided between each atomizing chamber 1021 to isolate them from each other. The isolation section 210 is provided to prevent eddies from being generated when the aerosols in each atomizing chamber 1021 are mixed, which would affect the airflow stability.

[0046] In some embodiments, please refer to Figure 2The isolation section 210 extends at least partially into the air outlet channel 1023, dividing the inlet of the air outlet channel 1023 to connect the corresponding atomizing chambers 1021. Specifically, the isolation section 210 divides the inlet of the air outlet channel 1023 into multiple inlet sections 10231, each inlet section 10231 being used to guide the aerosol in each atomizing chamber 1021 into the air outlet channel 1023. In this embodiment, by extending the isolation section 210 into the air outlet channel 1023, the aerosols in each atomizing chamber 1021 will not meet before entering the air outlet channel 1023, thus preventing the generation of eddies and ensuring airflow stability.

[0047] In some embodiments, please refer to Figures 2 to 4 The bottom of the isolation section 210 has a first arc-shaped surface 211 for guiding the airflow in the atomizing chamber 1021 to each inlet section 10231, so as to ensure that the airflow in the atomizing chamber 1021 smoothly changes from the lateral direction to the longitudinal direction.

[0048] In some embodiments, please refer to Figure 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 surface or a curved surface, so that the airflow in the atomizing chamber 1021 can smoothly enter the air outlet channel 1023, which can ensure smooth airflow, stable function during use, and avoid adverse phenomena such as suction and leakage.

[0049] In some embodiments, the atomizing device includes a nozzle 400, a liquid storage tank 100, an internal support 200, and a housing 300. The internal support 200 and the liquid storage tank 100 together enclose atomizing chamber 1021. The housing 300 is fitted outside the internal support 200, and the nozzle 400 is fitted outside the liquid storage tank 100. The nozzle 400 and the housing 300 are interconnected. A liquid storage chamber 101 is formed in the liquid storage tank 100. An air outlet channel 1023 passes through the liquid storage tank 100 and the nozzle 400, respectively. An air inlet channel 1022 is formed on the side of the internal support 200 facing the housing 300. By forming the air inlet channel 1022 on the side of the internal support 200 facing the housing 300, it is convenient to control the gas flow rate and also leave space for other structures. For example, the air inlet channel 1022 can be separated from the control unit 600, thereby facilitating air intake control, controlling airflow noise, and preventing liquid leakage to the control unit 600.

[0050] In some embodiments, please refer to Figure 5An intake passage 1022 is formed on one side of the internal bracket 200 along the second direction Y, and the intake passages 1022 are spaced apart along the first direction X. A mounting cavity is formed on the other side of the internal bracket 200 along the second direction Y. The mounting cavity is used to mount the control unit 600, thereby isolating the intake passages 1022 from the control unit 600.

[0051] In some embodiments, please refer to Figure 5 and Figure 9 The atomizing device also includes an air inlet 1026, which communicates with the outside atmosphere. One end of each air inlet channel 1022 is connected to the air inlet 1026, and the other end of each air inlet channel 1022 is connected to the atomizing chamber 1021. After entering the atomizing device through the air inlet 1026, the outside atmosphere enters the corresponding atomizing chamber 1021 through each air inlet channel 1022, carrying aerosols into the outlet channels 1023, where they are mixed and then inhaled by the user.

[0052] In some embodiments, the air inlet 1026 is formed at the center of the side of the housing 300 opposite to the nozzle 400, and each air inlet channel 1022 is symmetrically distributed relative to the centerline of the air inlet 1026. It can be understood that in other embodiments of this application, the atomizing device may also include multiple air inlets 1026, each air inlet 1026 communicating with the external atmosphere, one end of each air inlet channel 1022 communicating with each air inlet 1026, and the other end of each air inlet channel 1022 communicating with the atomizing chamber 1021. That is, the air intake of each atomizing unit is independently configured, which is not limited to a single configuration here.

[0053] In some embodiments, please refer to Figure 5 Each air intake channel 1022 is formed within the internal support 200. Specifically, the internal support 200 is recessed along one of the second directions Y to form each air intake channel 1022. The air intake channels 1022 converge at the center of the side of the internal support 200 away from the liquid storage tank 100 to form a converging port 1027, which communicates with the air intake hole 1026 of the outer shell 300. The second direction Y is perpendicular to the first direction X. The first direction X can be referred to as the left-right direction or width direction of the atomizing device, and the second direction Y can be referred to as the front-back direction or thickness direction of the atomizing device.

[0054] In some embodiments, the liquid storage chamber 100 and the internal support 200 are distributed along the longitudinal direction of the atomizing device and are connected to each other by insertion. The internal support 200 is snapped into the outer shell 300, and the nozzle 400 and the outer shell 300 abut against each other along the longitudinal direction of the atomizing device and are snapped into each other.

[0055] In some embodiments, please refer to Figure 2 and Figure 4The internal support 200 has a recessed groove on the side facing the liquid storage tank 100. The center of the groove is directly opposite the air outlet channel 1023 in the longitudinal direction. The isolation part 210 extends longitudinally from the bottom of the center of the groove into the air outlet channel 1023. The bottom cross-sectional area of ​​the isolation part 210 gradually decreases from bottom to top to form first arc-shaped surfaces 211 on its surface.

[0056] In some embodiments, please refer to Figure 3 The bottom of the atomizing chamber 1021 is provided with a throttle hole 1024, which connects the atomizing chamber 1021 with the air inlet channel 1022. The throttle hole 1024 can be used to adjust the airflow, thereby controlling the suction resistance of the atomizing unit to meet the user's inhalation needs.

[0057] In some embodiments, please refer to Figure 3 and Figure 4 An air intake column 220 is provided in the atomizing chamber 1021. The air intake column 220 protrudes from the bottom of the atomizing chamber 1021 at a preset height, and the bottom end of the air intake column 220 is connected to the throttle orifice 1024. The airflow enters the air intake column 220 after passing through the throttle orifice 1024, ensuring the airflow direction. Simultaneously, the air intake column 220 delivers the intake air to the preset height within the atomizing chamber 1021, thereby reducing the problem of condensate flowing into the intake channel 1022 and thus reducing the problem of blockage in the intake channel 1022.

[0058] In some embodiments, please refer to Figure 3 That is, the intake column 220 is roughly funnel-shaped, so that the gas at the outlet of the intake column 220 can quickly disperse to the surroundings and prevent the gas from condensing at the top.

[0059] In some embodiments, the longitudinal distance from the top surface of the air intake column 220 to the heating element 500 is greater than or equal to 0.5 mm, for example, it can 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, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, or 2.0 mm. In this embodiment, the longitudinal distance from the top surface of the air intake column 220 to the heating element 500 is limited to prevent the gas entering from the air intake column 220 from not being able to disperse quickly due to the distance between the air intake column 220 and the heating element 500 being too small, thereby causing gas condensation.

[0060] In some embodiments, the dimensions of the air intake column 220 and the heating element 500 in the lateral direction of the atomizing device are greater than 0.5 mm, for example, they can 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, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, or 2.0 mm. This arrangement allows the gas in the air intake column 220 to fully contact the aerosol to carry it away.

[0061] In some embodiments, please refer to Figure 3 An arc-shaped guide surface 110 is formed on the top inner wall of the atomizing chamber 1021 at the position corresponding to the outlet of the air intake column 220. The arc-shaped guide surface 110 guides the gas entering from the air intake column 220 towards the heating element 500, so that the air flows more smoothly over the atomizing surface of the heating element 500 after entering the atomizing chamber 1021, preventing the generation of eddies. Specifically, the arc-shaped guide surface 110 is formed on the side of the liquid storage tank 100 facing the internal support 200.

[0062] Optionally, the arc-shaped guide surface 110 is arc-shaped, and the arc-shaped guide surface 110 faces the air intake column 220 and the heating element 500, thereby guiding the gas.

[0063] In some embodiments, please refer to Figure 3 and Figure 5 A connecting channel 1025 is provided between the intake channel 1022 and the throttle orifice 1024. The cross-sectional dimension of the connecting channel 1025 is larger than that of the throttle orifice 1024, and the cross-sectional dimension of the connecting channel 1025 is larger than that of the intake channel 1022. The connecting channel 1025 extends from the intake channel 1022 along the second direction Y to the bottom of the throttle orifice 1024 to communicate with the throttle orifice 1024.

[0064] In some embodiments, please refer to Figure 4 The atomizing device also includes a battery 640 and a control board 610. The battery 640 is electrically connected to the control board 610, and the control board 610 is electrically connected to each heating element 500. The control board 610 is electrically connected to a signal input module, which inputs control signals to the control board 610. The control board 610 controls the on / off connection of the battery 640 and each heating element 500 according to the control signals.

[0065] The signal input module can be a button 620, a touch screen, or a voice input module. The control signals input to the signal input module include control signals that control the battery 640 to simultaneously power all heating elements 500, or control signals that control the battery 640 to power only some of the heating elements 500. For example, when there are two heating elements 500, the control signal can be a control signal that controls the battery 640 to power both heating elements 500 simultaneously, so that each heating element 500 heats and atomizes its corresponding atomizing medium to form an aerosol, thereby achieving an aerosol mixing effect; or, the control signal can also be a control signal that controls the battery 640 to power only one heating element 500. When there are three or more heating elements 500, the control signal can be a control signal that controls the battery 640 to power all heating elements 500 simultaneously, or a control signal that controls the battery 640 to power one or two heating elements 500, etc., without being limited to a single signal. The above settings allow users to select the operating mode of each heating element 500 according to their preferences and needs, meeting the usage requirements of different users.

[0066] In some embodiments, please refer to Figure 2 The signal input module includes a switch device 611, which is mounted on the control board 610 and communicates with the control board 610. The atomizing device also includes a button 620, which is mounted on the internal bracket 200 and / or the housing 300 and exposed in the housing 300. The user can press or toggle the button 620 to drive the switch device 611, thereby realizing the input of control signals.

[0067] In some embodiments, the atomizing device provides a set of electrodes 630 for each heating element 500. Each set of electrodes 630 includes two electrodes 630, which are respectively mounted on the internal bracket 200 and electrically connected to the heating element 500. The two electrodes 630 are also electrically connected to the control board 610, thereby achieving electrical connection between the control board 610 and the heating element 500. The control board 610, button 620, electrodes 630, and battery 640 constitute the control unit 600 of the atomizing device.

[0068] In some of these embodiments, please refer to Figure 6 Electrode 630 is a pin electrode 630, which is riveted and fixed to the internal support 200. The top ends of the two pin electrodes 630 elastically abut against the two ends of the heating element 500, and the bottom ends of the two pin electrodes 630 are electrically connected to the control board 610 through wires. The pin electrodes 630 and the internal support 200 can be riveted and sealed, eliminating the need for sealing with glue or other methods, thus allowing for more flexible assembly.

[0069] For details, please refer to Figure 3 and Figure 6 An annular groove 230 is recessed on the side of the internal support 200 facing the liquid storage tank 100. A sealing ring 700 is installed in the annular groove 230. The annular groove 230 surrounds the outside of each atomizing chamber 1021. The bottom periphery of the liquid storage tank 100 is inserted into the annular groove 230 and abuts against the sealing ring 700 to achieve a seal between the internal support 200 and the liquid storage tank 100 and ensure normal suction resistance.

[0070] Specifically, the bottom of the liquid storage tank 100 has an installation groove that communicates with the liquid storage cavity 101. The heating element 500 is sealed and installed in the installation groove by a silicone sleeve 800. The silicone sleeve 800 is press-fitted with the inner wall of the installation groove. The ejector electrode 630 abuts against the heating element 500, thereby ensuring the stability of the contact resistance between the ejector electrode 630 and the heating element 500.

[0071] In other embodiments of this application, please refer to Figure 7 Electrode 630 can also be a spring sheet, which is riveted to the internal support 200 and sealed with glue at the opening of the internal support 200. One end of the spring sheet abuts against the heating element 500, and the other end of the spring sheet is directly welded to the control board 610. The spring sheet method eliminates the need for wire bonding, and the larger area of ​​the spring sheet is beneficial for heating, reduces liquid accumulation, and improves the utilization rate of the atomizing medium.

[0072] In some embodiments, please refer to Figure 3 and Figure 8 The liquid storage chamber 100 also has a liquid outlet 120, a ventilation channel 103, and a blocking member 130; the liquid outlet 120 is connected to the bottom of the liquid storage chamber 101; the ventilation channel 103 has a first port 1031 and a second port, the first port 1031 is connected to the liquid storage chamber 101, and the second port is connected to the external atmosphere; the blocking member 130 is disposed in the liquid storage chamber 101, and the blocking member 130 is located on the side of the first port 1031 facing the liquid outlet 120, so as to block the air bubbles flowing from the first port 1031 to the liquid outlet 120.

[0073] The lower liquid outlet 120 is connected to the bottom of the liquid storage chamber 101, meaning that the lower liquid outlet 120 extends outward from the bottom of the liquid storage chamber 101 and is connected to the liquid storage chamber 101, so that the atomizing medium in the liquid storage chamber 101 can flow to the heating element 500 through the lower liquid outlet 120.

[0074] The first port 1031 of the ventilation channel 103 is connected to the liquid storage chamber 101, and the second port of the ventilation channel 103 is connected to the external atmosphere. The ventilation channel 103 extends from the first port 1031 to the second port. The first port 1031 of the ventilation channel 103 can be located on the bottom or peripheral sidewall of the liquid storage chamber 101. The second port of the ventilation channel 103 can be directly connected to the external atmosphere, or it can be connected to the external atmosphere through the atomizing chamber 1021.

[0075] The blocking member 130 is located on the side of the first port 1031 facing the lower liquid outlet 120. This means the blocking member 130 is positioned on the side of the first port 1031 facing the lower liquid outlet 120, and is spaced apart from the first port 1031. The blocking member 130 blocks the first port 1031 so that the first port 1031 does not face directly towards the lower liquid outlet 120. In other words, air bubbles generated when entering the liquid storage chamber 101 from the first port 1031 will not flow directly towards the lower liquid outlet 120, but will be blocked by the blocking member 130 and then slowly rise and disappear.

[0076] In some embodiments, please refer to Figure 8 The first port 1031, the blocking member 130 and the liquid outlet 120 are distributed sequentially along the first direction X; along the first direction X, the first projection of the blocking member 130 covers the second projection of the first port 1031.

[0077] Wherein, the first direction X can be the front-back direction of the atomizing device, the left-right direction of the atomizing device, or even a direction that forms an angle with the front-back direction of the atomizing device. This embodiment will be described using the left-right direction of the atomizing device as an example.

[0078] The first port 1031, the blocking member 130, and the liquid outlet 120 are distributed sequentially along the first direction X. This means that the blocking member 130 is positioned between the distribution directions of the first port 1031 and the liquid outlet 120, that is, the blocking member 130 is positioned on the side of the first port 1031 facing the liquid outlet 120, thereby effectively blocking the gas bubbles formed by the gas entering the liquid storage chamber 101 from the first port 1031.

[0079] The shape of the second projection of the first port 1031 along the first direction X can vary depending on the formation position of the first port 1031. For example, when the bottom surface of the liquid storage cavity 101 is a plane, the second projection of the first port 1031 along the first direction X is a line; or when the bottom surface of the liquid storage cavity 101 is a surface inclined downwards towards the liquid outlet 120, the second projection of the first port 1031 along the first direction X is an ellipse or a flattened circle. However, regardless of whether the bottom surface of the liquid storage cavity 101 is a plane or an inclined surface, the first projection of the blocking member 130 along the first direction X can cover the second projection of the first port 1031, that is, the blocking member 130 can completely block the first port 1031, thereby effectively blocking the gas bubbles formed by the gas entering the liquid storage cavity 101 from the first port 1031.

[0080] In this application, because bubbles have a certain degree of fluidity, measures are taken to prevent bubbles from bypassing the blocking member 130 and flowing down to the liquid outlet 120. In some embodiments, please refer to... Figure 8 The blocking member 130 extends at least 0.5 mm from the opposite ends of the first port 1031 along the second direction Y; the second direction Y, the first direction X, and the longitudinal direction of the atomizing device are perpendicular to each other.

[0081] Please see Figure 8 Let d1 be the distance between one end of the blocking member 130 along the second direction Y and the corresponding end of the first port 1031 along the second direction Y, and let d2 be the distance between the other end of the blocking member 130 along the second direction Y and the corresponding end of the first port 1031 along the second direction Y. Then d1 is greater than or equal to 0.5 mm, and d2 is greater than or equal to 0.5 mm. Specifically, the dimensions of d1 and d2 can 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, and 1.3 mm, or even more, as long as the design of the blocking member 130 does not affect the fluidity of the liquid. With this setting, the blocking member 130 can block the air bubbles entering from the first port 1031 along the second direction Y to a certain extent, preventing the air bubbles from bypassing the blocking member 130 and flowing down to the liquid outlet 120 along the second direction Y.

[0082] In this application, the positional relationship between the first port 1031 and the liquid outlet 120 can be set according to the actual situation. The first port 1031 can be located on any side of the liquid outlet 120, for example, the first port 1031 can be located in front of, behind, to the left or right of the liquid outlet 120. In addition, the first port 1031 can be located at the center of the liquid outlet 120 along the second direction Y, or the first port 1031 can be located near the edge of the liquid outlet 120 along the second direction Y.

[0083] As an example, please see Figure 8The first port 1031 is located near the edge of the liquid outlet 120 along the second direction Y, and the size of the liquid outlet 120 along the second direction Y is much larger than the size of the first port 1031 along the second direction Y. In this case, d2 can be designed to be larger than d1 so that the blocking member 130 can effectively block air bubbles, while the size of d1 can be designed to be relatively small to reduce the overall size of the blocking member 130 along the second direction Y, thereby reducing the impact of the blocking member 130 on the liquid flow.

[0084] As another example, the first port 1031 is located near the center of the lower liquid outlet 120 along the second direction Y. At this time, the center surface of the blocking member 130 along the second direction Y can coincide with the center surface of the first port 1031 along the second direction Y. That is, the opposite ends of the blocking member 130 along the second direction Y extend by the same amount relative to the opposite ends of the first port 1031 along the second direction Y.

[0085] In some embodiments, please refer to Figure 8 The liquid outlet 120 has a rectangular cross-section to ensure that the atomizing medium in the liquid storage chamber 101 flows evenly to the liquid outlet 120 for liquid discharge. It is understood that in other embodiments of this application, the cross-section of the liquid outlet 120 may also be square, circular, elliptical or other combined shapes, wherein a combined shape refers to a closed shape formed by connecting the beginning and end of straight lines and / or curves in sequence.

[0086] In one embodiment, see Figure 8 The first port 1031 has a circular cross-section and an inner diameter of 0.6mm-0.7mm to allow gas to enter the liquid storage chamber 101 at a uniform speed. It is understood that in other embodiments of this application, the cross-section of the first port 1031 may also be square, elliptical, or other combined shapes, wherein a combined shape refers to a closed shape formed by the sequential connection of straight lines and / or curves.

[0087] In this application, the number of ventilation channels 103 can be one or more. When there are multiple ventilation channels 103, the first port 1031 of each ventilation channel 103 is evenly distributed around the liquid outlet 120, so that the ventilation effect of the ventilation channels 103 is evenly distributed.

[0088] As an example, please refer to Figure 8. The number of ventilation channels 103 is two, with the first ports 1031 of the two ventilation channels 103 located at two opposite corners of the liquid outlet 120. The first ports 1031 of the two ventilation channels 103 are symmetrically arranged with respect to the centerline of the liquid outlet 120. In other embodiments, the number of ventilation channels 103 may also be three, four, or more.

[0089] In some embodiments, the blocking member 130 extends at least 0.5 mm above the first port along the longitudinal direction of the atomizing device. Specifically, the blocking member 130 may extend 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, or 1.6 mm above the first port. Theoretically, the higher the height of the blocking member 130, the better. Of course, the processing difficulty of the blocking member 130 should also be considered. Therefore, the height of the blocking member 130 is preferably not more than 3.0 mm.

[0090] In some embodiments, the blocking member 130 is integrally formed on the inner wall of the liquid storage cavity 101, that is, the blocking member 130 is integrally connected with the liquid storage tank 100 formed in the liquid storage cavity 101. The blocking member 130 and the liquid storage tank 100 are integrally formed, which not only reduces the processing technology of the blocking member 130, but also reduces the assembly technology of the blocking member 130, while ensuring the blocking effect of the blocking member 130. It can be understood that in other embodiments of the application, the blocking member 130 can also be fixed to the inner wall of the liquid storage cavity 101. Specifically, the blocking member 130 is independently processed and set, and then the blocking member 130 is fixed to the inner wall of the liquid storage cavity 101 by means of interference fit, bonding, screw tightening, secondary injection molding, etc.

[0091] In some embodiments, the blocking member 130 has a long and flat structure, and the size of the blocking member 130 along the second direction Y is much larger than the size of the blocking member 130 along the first direction X. This arrangement makes the blocking ability of the blocking member 130 along the second direction Y sufficiently large, and the volume of the blocking member 130 in the liquid storage cavity 101 as small as possible.

[0092] In some embodiments, the second port of the ventilation channel 103 is formed in the silicone sleeve 800, that is, the ventilation channel 103 is formed in the liquid storage tank 100 and the silicone sleeve 800.

[0093] In some embodiments, please refer to Figure 9The atomizing device also includes an airflow sensor 900 and a sealing sleeve 1000. The airflow sensor 900 is electrically connected to the control board 610, and the sealing sleeve 1000 is fitted over the airflow sensor 900. The atomizing device also has a starting airway 104, which is spaced apart from the main airway 102. The main airway 102 includes an air inlet channel 1022, an atomizing chamber 1021, and an air outlet channel 1023. The starting airway 104 is connected to the sealing sleeve 1000, and the top end of the starting airway 104 is connected to the top end of the main airway 102. When the user inhales through the nozzle 400, because the starting airway 104 is connected to the main airway 102, the air in the starting airway 104 can be simultaneously driven. The airflow passes through the starting airway 104 and transmits negative pressure to the airflow sensor 900, which then starts working under the action of negative pressure. In this embodiment, by designing the starting airway 104 and the main airway 102 as independent separate entities, and connecting them at the top, the problem of simultaneous blockage of the main airway 102 and the starting airway 104 can be effectively avoided. Furthermore, even if the main airway 102 is blocked, the independent design of the starting airway 104 allows the airflow sensor 900 to be activated smoothly during suction. When the heating element 500 starts heating, it can reduce the viscosity of the atomizing medium and clear the blockage in the device.

[0094] Specifically, the liquid storage chamber 100 is provided with a connection port at the top of the start-up air passage 104, and the connection port enables the air outlet passage 1023 to be connected to the start-up air passage 104.

[0095] In some embodiments, please refer to Figure 9 The sealing sleeve 1000 has a receiving groove 1001 and a negative pressure groove 1002. The airflow sensor 900 is received in the receiving groove 1001. The negative pressure groove 1002 is connected to the receiving groove 1001 and is connected to the starting air passage 104, so that the negative pressure can be transmitted to the airflow sensor 900 through the negative pressure groove 1002.

[0096] In some embodiments, please refer to Figure 2 A suction nozzle seal 1100 abuts against the liquid storage chamber 100, ensuring a sealed connection between the main air passage 102 and the start-up air passage 104. The suction nozzle seal 1100 also ensures a sealed top of the liquid storage chamber 101.

[0097] In some embodiments, please refer to Figure 1 A display screen 1200 is mounted on the surface of the housing 300. The display screen 1200 is electrically connected to the control board 610. The display screen 1200 is used to display the working status and battery level of the atomizing device, including which heating element 500 is in operation. In other embodiments of this application, the housing 300 may not have the display screen 1200 installed. Please refer to [link to relevant documentation]. Figure 10Instead, indicator lights are installed on the control board 610, and through holes 310 are provided on the housing 300 corresponding to the position of the indicator lights. The indicator lights are used to display the usage status of each heating element 500 and the power level.

[0098] In this application, the capacity of each liquid storage chamber 101 can be set according to the implementation requirements. For example, the capacity of the liquid storage chamber 101 can be 0.5ml or 1ml.

[0099] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
