Description

Technical Field

[0001] This application belongs to the field of aerosol generation technology, and more specifically, relates to an atomizer and atomizing device. Background Technology

[0002] Atomizers typically store the atomizing medium in a reservoir and atomize it using a coil to generate an aerosol. The porous structure of the coil is generally used to lock in the atomizing medium and prevent leakage. However, when the reservoir is large, the coil's ability to retain liquid may be insufficient, leading to leakage and negatively impacting the user's experience. Utility Model Content

[0003] The purpose of this application is to provide an atomizer and atomizing device to solve the technical problem of easy leakage in existing atomizers.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: an atomizer is provided, the atomizer including an atomizing core, the atomizer also having a liquid storage chamber and a ventilation channel, the liquid storage chamber including at least a first liquid chamber and a second liquid chamber that are interconnected, the liquid inlet surface of the atomizing core being in liquid communication with the first liquid chamber, the air inlet end of the ventilation channel being in communication with the external atmosphere, and the air outlet end of the ventilation channel being in communication with the second liquid chamber.

[0005] In some embodiments, the first liquid chamber and the second liquid chamber are connected by a connecting channel, and the connecting channel is filled with a first liquid suction element.

[0006] In some embodiments, the first liquid-absorbing member extends toward the second liquid cavity to cover the bottom wall of the second liquid cavity;

[0007] And / or, the first liquid suction element extends toward the first liquid cavity to cover the bottom wall of the first liquid cavity.

[0008] In some embodiments, the atomizer further includes a suction airway, and the air inlet of the ventilation channel is connected to the suction airway.

[0009] In some embodiments, the atomizer further includes a second liquid suction element, which is connected to the air exchange channel and the second liquid chamber.

[0010] In some embodiments, the atomizing core includes a liquid guiding element, the density of which is greater than the density of the second liquid-absorbing element.

[0011] In some embodiments, the atomizer further includes a one-way ventilation valve, wherein the ventilation channel is formed in the one-way ventilation valve.

[0012] In some embodiments, the atomizer has a liquid inlet communicating with the first liquid chamber and the atomizing core, the first liquid chamber being provided with a third liquid suction member, the third liquid suction member at least partially covering the liquid inlet.

[0013] In some embodiments, the first liquid chamber and the second liquid chamber are connected by a connecting channel, and the atomizer has a liquid inlet connecting the first liquid chamber and the atomizing core; the connecting channel is filled with a liquid-absorbing structure, the liquid-absorbing structure extends toward the second liquid chamber to cover the bottom wall of the second liquid chamber, and the liquid-absorbing structure connects the ventilation channel and the second liquid chamber; the liquid-absorbing structure extends toward the first liquid chamber to cover the bottom wall of the first liquid chamber, and the liquid-absorbing structure at least covers part of the liquid inlet.

[0015] The beneficial effects of the atomizer and atomizing device provided in this application are as follows: By dividing the liquid storage chamber into a first liquid chamber and a second liquid chamber, connecting the atomizing core to the liquid in the first liquid chamber, and connecting the ventilation channel to the second liquid chamber, ventilation is primarily carried out through the ventilation channel. This configuration ensures that during atomization, the first liquid chamber remains full until the atomizing medium in the second liquid chamber is consumed. In other words, the atomizing core remains fully immersed in the atomizing medium until the atomizing medium in the second liquid chamber is completely consumed. This allows the surface tension of the atomizing medium after filling the atomizing core to lock in the atomizing medium, thereby preventing leakage. Attached Figure Description

Therefore, they should not be construed as limitations on this application.

[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] First, please refer to Figure 1 This application provides an atomizing device, including a power supply structure 2 and an atomizer 1. The atomizer 1 stores an atomizing medium. The power supply structure 2 is used to supply power to the atomizer 1. The atomizer 1 is used to atomize the atomizing medium to form an aerosol after being powered on, and deliver it out for the user to inhale.

[0034] Please see Figures 2 to 4 The atomizer 1 provided in the embodiments of this application will now be described.

[0035] The atomizer 1 includes an atomizing core 100 and a liquid storage chamber 101 and a ventilation channel 102. The liquid storage chamber 101 includes at least a first liquid chamber 1011 and a second liquid chamber 1012 that are interconnected. The liquid inlet surface of the atomizing core 100 is in liquid communication with the first liquid chamber 1011. The air inlet end 1021 of the ventilation channel 102 is in communication with the outside atmosphere, and the air outlet end 1022 of the ventilation channel 102 is in communication with the second liquid chamber 1012.

[0036] Initially, both the first liquid chamber 1011 and the second liquid chamber 1012 are filled with atomizing medium. When the user inhales, the atomizing core 100 atomizes the atomizing medium to generate an aerosol. The amount of atomizing medium in the first liquid chamber 1011 decreases, and the second liquid chamber 1012 replenishes the atomizing medium in the first liquid chamber 1011. The decrease in the atomizing medium in the second liquid chamber 1012 creates negative pressure, requiring the addition of outside air.

[0037] During ventilation, since the atomizing core 100 is filled with atomizing medium, the negative pressure required for gas to pass through the atomizing core 100 is greater than the negative pressure required for gas to pass through the ventilation channel 102. Therefore, the atomizer 1 generally ventilates through the ventilation channel 102.

[0038] Meanwhile, the atomizer 1 is ventilated through the ventilation channel 102. During ventilation, outside air enters the top of the second liquid chamber 1012 to squeeze the atomizing medium in the second liquid chamber 1012 into the first liquid chamber 1011. Therefore, the atomizing medium consumed by the suction in the first liquid chamber 1011 is replenished through the second liquid chamber 1012, so that the atomizing core 100 remains fully immersed in the atomizing medium until the atomizing medium in the second liquid chamber 1012 is consumed. The surface tension of the atomizing medium after filling the atomizing core 100 is used to lock in the atomizing medium and prevent leakage.

[0039] In this embodiment, the atomizer 1 divides the liquid storage chamber 101 into a first liquid chamber 1011 and a second liquid chamber 1012. The atomizing core 100 is connected to the first liquid chamber 1011, and the ventilation channel 102 is connected to the second liquid chamber 1012. This allows ventilation to primarily occur through the ventilation channel 102. This configuration ensures that during atomization, the first liquid chamber 1011 remains full until the atomizing medium in the second liquid chamber 1012 is consumed. In other words, the atomizing core 100 remains fully immersed in the atomizing medium until it is completely consumed in the second liquid chamber 1012. This surface tension after the atomizing medium fills the atomizing core 100 helps to retain the atomizing medium, thus preventing leakage.

[0040] In other embodiments of this application, please refer to Figure 5 The liquid storage chamber 101 may also include at least one third liquid chamber 1013. The third liquid chamber 1013 may be directly connected to the first liquid chamber 1011. The third liquid chamber 1013 may also be connected to the first liquid chamber 1011 through the second liquid chamber 1012. The atomizer 1 may be provided with a ventilation channel 102 corresponding to the third liquid chamber 1013. Alternatively, the atomizer 1 may not be provided with a ventilation channel 102 at the position corresponding to the third liquid chamber 1013.

[0041] In some embodiments, please refer to Figure 4The first liquid chamber 1011 and the second liquid chamber 1012 are connected by a connecting channel 1014. The connecting channel 1014 is located at the bottom of the liquid storage chamber 101, that is, the bottom of the first liquid chamber 1011 is connected to the bottom of the second liquid chamber 1012. This allows the atomizing medium in the second liquid chamber 1012 to flow to the first liquid chamber 1011 under the action of gravity without the need for external driving force.

[0042] In some embodiments, please refer to Figure 2 and Figure 4 A partition 250 is provided in the liquid storage chamber 101. The partition 250 extends from the top wall of the liquid storage chamber 101 to near the bottom wall of the liquid storage chamber 101, and the partition 250 and the bottom wall of the liquid storage chamber 101 form a connecting channel 1014. Specifically, when the first liquid chamber 1011 and the second liquid chamber 1012 are spaced apart along the first direction X, the width of the connecting channel 1014 along the second direction Y is the same as the width of the partition 250 along the second direction Y. The first direction X and the second direction Y are both transverse directions perpendicular to the longitudinal direction Z of the atomizer 1. This arrangement can improve the uniformity of communication between the first liquid chamber 1011 and the second liquid chamber 1012, and improve the efficiency and uniformity of the atomizing medium entering the first liquid chamber 1011 from the second liquid chamber 1012. Understandably, in other embodiments of this application, the partition 250 may be extended directly to the bottom wall of the liquid storage cavity 101, and then a hole may be made in the partition 250 to form a connecting channel 1014, wherein the shape of the connecting channel 1014 may be circular, elliptical, square or other shapes.

[0043] In some embodiments, please refer to Figure 4 and Figure 6 The first liquid chamber 1011 and the second liquid chamber 1012 are connected by a connecting channel 1014, which is filled with a first liquid-absorbing element 510. The first liquid-absorbing element 510 ensures that the first liquid chamber 1011 and the second liquid chamber 1012 are not directly connected. The atomizing medium in the second liquid chamber 1012 is absorbed by the first liquid-absorbing element 510 and then guided to the first liquid chamber 1011. Conversely, the atomizing medium in the first liquid chamber 1011 is absorbed by the first liquid-absorbing element 510 and then guided to the second liquid chamber 1012. This prevents the atomizer 1 from being tilted at different angles, thus preventing the atomizing medium in the first liquid chamber 1011 from completely flowing into the second liquid chamber 1012 and causing leakage due to air exchange with the atomizing core 100.

[0044] Preferably, the first liquid-absorbing element 510 fills the connecting channel 1014, thereby achieving a better leak-proof effect.

[0045] In some embodiments, please refer to Figure 6The first liquid suction member 510 extends towards the second liquid cavity 1012 to cover the bottom wall of the second liquid cavity 1012. That is, the first liquid suction member 510 can absorb the atomizing medium at each position at the bottom of the second liquid cavity 1012 and guide it to the first liquid cavity 1011. This ensures that even if the atomizer 1 is tilted at different angles, the atomizing medium at each position at the bottom of the second liquid cavity 1012 can be guided into the first liquid cavity 1011, avoiding the situation where the second liquid cavity 1012 cannot supply liquid to the first liquid cavity 1011 due to the tilt of the atomizer 1.

[0046] In some other embodiments of this application, the first liquid suction member 510 extends toward the first liquid cavity 1011 to cover the bottom wall of the first liquid cavity 1011. This arrangement ensures that when the atomizer 1 is tilted at different angles, the first liquid suction member 510 can guide the atomizing medium at each position at the bottom of the second liquid cavity 1012 to each position at the bottom of the first liquid cavity 1011, so that the atomizing medium is evenly distributed at the bottom of the second liquid cavity 1012, thereby ensuring that the atomizing medium can cover the atomizing core 100.

[0047] In other embodiments of this application, please refer to Figure 9 The first liquid suction member 510 extends toward the second liquid cavity 1012 to cover the bottom wall of the second liquid cavity 1012, and the first liquid suction member 510 extends toward the first liquid cavity 1011 to cover the bottom wall of the first liquid cavity 1011.

[0048] In some embodiments, the first liquid-absorbing element 510 includes a first liquid-absorbing cotton, which absorbs and guides the atomizing medium. This not only has a simple structure and low cost but also provides good liquid guiding effect. It is understood that in other embodiments of this application, the first liquid-absorbing element 510 may also include a porous structure made of porous ceramic or other materials; this is not a limiting factor.

[0049] In some embodiments, please refer to Figure 4 and Figure 6 The atomizer 1 includes an upper seat 200 and a bottom cover 300. A liquid storage chamber 101 is formed in the upper seat 200, and a partition 250 is formed in the upper seat 200. The opening of the liquid storage chamber 101 faces the upper seat 200. The bottom cover 300 is placed on the bottom opening of the liquid storage chamber 101 and is snapped into the upper seat 200. The first absorbent cotton is pressed between the partition 250 and the bottom cover 300, thereby ensuring that the first liquid chamber 1011 and the second liquid chamber 1012 are not directly connected.

[0050] For details, please refer to Figure 4 The atomizer 1 also includes a sealing element 400, which is installed on the bottom cover 300 and abuts between the outer peripheral surface of the bottom cover 300 and the inner peripheral surface of the upper seat 200 to form a sealed connection between the bottom cover 300 and the upper seat 200. The first absorbent cotton abuts between the sealing element 400 and the partition 250.

[0051] Optionally, the seal 400 is made of silicone material to give it good elasticity and sealing performance. It is understood that in other embodiments of this application, the seal 400 may also be made of materials such as rubber, plastic, or ceramic; this is not a limiting factor.

[0052] In some embodiments, please refer to Figure 4 The atomizer 1 also has a suction airway 103, and the air inlet 1021 of the ventilation channel 102 is connected to the suction airway 103. It should be noted that the suction airway 103 is the channel through which the atomizer 1 achieves airflow through inhalation, causing the airflow to carry the atomized medium to the user's mouth. The atomizing surface of the atomizing core 100 is connected to the gas in the suction airway 103. When the user inhales from the atomizer 1, external air enters the suction airway 103 to carry away the atomized medium generated by the atomizing core 100 and delivers the atomized medium to the user's mouth.

[0053] Since the air inlet 1021 of the ventilation channel 102 is connected to the suction airway 103, when the user inhales the atomizer 1, the air inlet 1021 of the ventilation channel 102 is kept under negative pressure during the inhalation process. This ensures that the ventilation channel 102 does not exchange air during inhalation and only does so after the inhalation process is completed. Simultaneously, the negative pressure in the second liquid chamber 1012 continuously increases during inhalation, allowing the second liquid chamber 1012 to retain the atomizing medium and preventing leakage during inhalation.

[0054] In some embodiments, please refer to Figure 4 The atomizer 1 also has an atomizing chamber 1034 and an air guide channel 1035. The atomizing surface of the atomizing core 100 is in gas communication with the atomizing chamber 1034, and the air guide channel 1035 is in communication with the atomizing chamber 1034. The bottom cover 300 and the sealing member 400 are fastened together to form an airflow chamber 1032. The bottom cover 300 has an air inlet 1031 that communicates with the airflow chamber 1032. The air inlet 1031 is used to introduce external airflow into the airflow chamber 1032. The sealing member 400 has a connection port 1033 that connects the airflow chamber 1032 and the atomizing chamber 1034. The air inlet 1031, the airflow chamber 1032, the connection port 1033, the atomizing chamber 1034, and the air guide channel 1035 together form a suction airway 103. The air inlet end 1021 of the ventilation channel 102 is in communication with the airflow chamber 1032. The airflow cavity 1032 not only connects the air exchange channel 102 with the suction air channel 103, but also receives the liquid leakage generated from the atomizing core 100.

[0055] In some embodiments, please refer to Figure 4The air inlet 1031 and the connector 1033 are offset laterally along the atomizer 1 to prevent the atomizing medium leaking from the atomizing core 100 from dripping into the air inlet 1031.

[0056] In some embodiments, please refer to Figure 7 The atomizer also includes a second liquid suction element 520, which connects the ventilation channel 102 and the second liquid chamber 1012. By connecting the ventilation channel 102 and the second liquid chamber 1012 through the second liquid suction element 520, when ventilation occurs through the ventilation channel 102, the gas entering the second liquid chamber 1012 from the outlet 1022 of the ventilation channel 102 must pass through the second liquid suction element 520. This increases the resistance to airflow into the second liquid chamber 1012 and also increases the resistance to leakage of the atomizing medium from the second liquid chamber 1012 to the ventilation channel 102. This improves the negative pressure value that the second liquid chamber 1012 can withstand and reduces the possibility of leakage through the ventilation channel 102. In addition, by placing a second liquid suction element 520 at the air outlet 1022 of the ventilation channel 102, ventilation will stop when the negative pressure in the second liquid chamber 1012 is balanced with the surface tension of the atomized medium on the second liquid suction element 520, so as to ensure that the liquid storage chamber 101 is kept under negative pressure to suck up the atomized medium in the liquid storage chamber 101 and avoid leakage.

[0057] For details, please refer to Figure 7 The bottom of the second liquid chamber 1012 has a connecting hole 420, which communicates with the air outlet 1022 of the ventilation channel 102. The second liquid suction member 520 is disposed on the bottom wall of the second liquid chamber 1012 and covers the connecting hole 420, thereby enabling the second liquid suction member 520 to communicate with the air outlet 1022 of the ventilation channel 102. It can be understood that in other embodiments of this application, the second liquid suction member 520 can also be housed in the connecting hole 420, which can also form a connection between the second liquid chamber 1012 and the ventilation channel 102.

[0058] Optionally, the second liquid-absorbing element 520 includes a second liquid-absorbing cotton. The porous structure of the second liquid-absorbing cotton forms gas communication between the second liquid chamber 1012 and the ventilation channel 102, and increases the airflow resistance between the second liquid chamber 1012 and the ventilation channel 102. It is understood that in other embodiments of this application, the second liquid-absorbing element 520 may also include a porous structure of porous ceramic or other materials, and is not limited here.

[0059] In some embodiments, please refer to Figure 7The atomizing core 100 includes a liquid guiding component 110, the density of which is greater than that of the second liquid absorption component 520. It should be noted that both the liquid guiding component 110 and the second liquid absorption component 520 are porous structures, each serving the functions of liquid absorption, liquid guiding, and liquid storage. Generally, whether the liquid guiding component 110 can retain the atomizing medium depends on its material, density, and liquid storage capacity. Within a certain range, the density of the liquid guiding component 110 is greater than that of the second liquid absorption component 520, indicating that the liquid-locking capacity of the liquid guiding component 110 is greater than that of the second liquid absorption component 520. This results in a greater negative pressure required for gas exchange through the atomizing core 100 than the negative pressure required for gas exchange through the second liquid absorption component 520 from the ventilation channel 102. Therefore, the atomizer 1 always exchanges gas through the ventilation channel 102. Understandably, in other embodiments of this application, the density of the liquid guide 110 may be set to be less than or equal to the density of the second liquid absorber 520, and the structure, shape and size of the ventilation channel 102 may be designed so that the negative pressure required for gas to pass through the atomizing core 100 is greater than the negative pressure required for gas to pass through the second liquid absorber 520 from the ventilation channel 102.

[0060] In some embodiments, please refer to Figure 9 The atomizer 1 also includes a one-way ventilation valve 600, with a ventilation channel 102 formed within it. The one-way ventilation valve 600 controls the unidirectional flow of air, allowing gas to pass freely in one direction while blocking its flow in the opposite direction. Specifically, the one-way ventilation valve 600 allows external airflow to enter the second liquid chamber 1012 for ventilation, but prevents the gas or liquid in the second liquid chamber 1012 from flowing out through it, thus preventing leakage of liquid from the second liquid chamber 1012. Understandably, in other embodiments of this application, the ventilation channel 102 may not be formed through the one-way ventilation valve 600. Instead, the flow resistance of the airflow in the ventilation channel 102 may be increased by other means, such as increasing the length of the ventilation channel 102 and decreasing the cross-sectional area of ​​the ventilation channel 102, thereby reducing the risk of leakage of the atomizing medium from the ventilation channel 102. In some other embodiments of this application, the ventilation channel 102 may also include capillary grooves formed between the one-way ventilation valve 600 and the inner wall of the atomizer, or capillary grooves formed on the inner wall of the atomizer. The capillary grooves may extend in a straight line, curve, or ring shape, and external air enters the second liquid chamber 1012 through the capillary grooves. At the same time, when the external air pressure changes, the atomizing medium may also flow into the ventilation channel 102 to balance the air pressure; when the external air pressure returns to normal, the atomizing medium in the ventilation channel 102 may be re-injected into the second liquid chamber 1012.

[0061] Specifically, the one-way valve 600 typically includes a valve body, a valve core, and a spring. When gas enters through the inlet 1021 of the one-way valve 600, the gas pressure overcomes the spring's resistance, pushing the valve core away from the valve seat, allowing gas to pass through the valve and enter the second liquid chamber 1012 from the outlet 1022. When gas attempts to enter from the outlet 1022 of the one-way valve 600, the valve core is pressed against the valve seat due to the spring's resistance and the gas's own pressure, thus preventing backflow of gas.

[0062] In some embodiments, please refer to Figure 8 The atomizer 1 has a liquid inlet 710 connecting the first liquid chamber 1011 and the atomizing core 100. The first liquid chamber 1011 is provided with a third liquid suction member 530, which at least partially covers the liquid inlet 710. This arrangement allows the third liquid suction member 530 to continuously and stably provide the atomizing medium to the liquid inlet 710, thereby continuously and stably providing the atomizing medium to the atomizing core 100. This ensures that the atomizing core 100 is always immersed in the atomizing medium, allowing the atomizer 1 to constantly exchange air through the ventilation channel 102, and also preventing the atomizing core 100 from dry-burning.

[0063] Optionally, the third liquid suction member 530 is located at the bottom of the first liquid chamber 1011.

[0064] For details, please refer to Figure 8 The atomizer 1 includes an inlet pipe 700, in which an atomizing core 100 is installed, forming the aforementioned atomizing chamber 1034. A first liquid chamber 1011 surrounds the inlet pipe 700, meaning the atomizing core 100 is located within the first liquid chamber 1011. Multiple liquid inlets 710 are formed on the circumferential sidewall of the inlet pipe 700. A third suction member 530 is located at the bottom of the first liquid chamber 1011 and sleeved outside the inlet pipe 700, with its top surface higher than the bottom surface of the liquid inlet 710, allowing the atomizing medium in the third suction member 530 to be guided into the atomizing core 100 through the liquid inlet 710.

[0065] In some embodiments, please refer to Figure 9The first liquid-absorbing element 510, the second liquid-absorbing element 520, and the third liquid-absorbing element 530 are integrally connected to form a liquid-absorbing structure 500. This liquid-absorbing structure 500 fills the connecting channel 1014 and extends towards the second liquid cavity 1012, covering its bottom wall. It is also located at the air outlet 1022 of the ventilation channel 102 to connect the second liquid cavity 1012 and the ventilation channel 102. The liquid-absorbing structure 500 extends towards the first liquid cavity 1011, covering its bottom wall and at least partially covering the liquid inlet 710. By integrating the first liquid-absorbing element 510, the second liquid-absorbing element 520, and the third liquid-absorbing element 530 into a single unit, the liquid-absorbing structure 500 achieves a simple structure, easy assembly, and diverse functions. It is understood that in other embodiments of this application, the first liquid suction member 510, the second liquid suction member 520 and the third liquid suction member 530 may also be separately arranged and assembled to form their respective functions, and this is not a unique limitation.

[0066] In some embodiments, please refer to Figure 9 The atomizer 1 has a liquid inlet 710 that connects the first liquid chamber 1011 and the atomizing core 100. The first liquid chamber 1011 and the second liquid chamber 1012 are connected by a connecting channel 1014. The connecting channel 1014 is filled with a liquid suction structure 500. The liquid suction structure 500 extends toward the second liquid chamber 1012 to cover the bottom wall of the second liquid chamber 1012. The liquid suction structure 500 connects the ventilation channel 102 and the second liquid chamber 1012. The liquid suction structure 500 extends toward the first liquid chamber 1011 to cover the bottom wall of the first liquid chamber 1011. The liquid suction structure 500 at least partially covers the liquid inlet 710. In this embodiment, the liquid suction structure 500 not only prevents leakage of the atomizing core 100 due to direct communication between the first liquid chamber 1011 and the second liquid chamber 1012, but also ensures that the atomizing medium in the second liquid chamber 1012 can be guided into the first liquid chamber 1011 regardless of the tilt angle of the atomizer 1. It also increases the resistance of the ventilation channel 102 to reduce leakage through the ventilation channel 102, and continuously supplies liquid to the atomizing core 100.

[0067] Optionally, the absorbent structure 500 is made of absorbent cotton material.

[0068] Optionally, the liquid absorption structure 500 is sheet-shaped and attached to the top side of the bottom cover 300. The liquid absorption structure 500 is wrapped around the liquid inlet pipe 700 and abuts against the partition 250 and the bottom cover 300.

[0069] In some embodiments, please refer to Figure 9The upper seat 200 has an installation channel 260. The upper seat 200 includes a top plate 210, a side plate 220, a first flange 230 and a second flange 240. The side plate 220 is integrally connected to the bottom periphery of the top plate 210. The first flange 230 protrudes from the bottom side of the top plate 210 and is connected to the liquid inlet pipe 700. The second flange 240 protrudes from the top side of the top plate 210 to form a mouthpiece for the user to inhale. The first flange 230 and the second flange 240 are arranged vertically and vertically respectively. The installation channel 260 passes through the first flange 230, the top plate 210 and the second flange 240 respectively.

[0070] Specifically, the partition 250 extends from the top plate 210 toward the bottom cover 300.

[0071] In some embodiments, please refer to Figure 9 The atomizer 1 also includes a connecting tube 800, with its two ends inserted into the liquid inlet tube 700 and the mounting channel 260, respectively, to establish communication between the liquid inlet tube 700 and the mounting channel 260. An air guide channel 1035 passes through both the connecting tube 800 and the upper seat 200. The connecting tube 800 improves the airflow smoothness between the liquid inlet tube 700 and the upper seat 200.

[0072] For details, please refer to Figure 9 The atomizer 1 also includes a sealing sleeve 900, which is sleeved between the connecting pipe 800 and the liquid inlet pipe 700, and the sealing sleeve 900 abuts against the first flange 230 and the liquid inlet pipe 700 in the axial direction, thereby forming a seal between the first flange 230, the liquid inlet pipe 700 and the connecting pipe 800.

[0073] Specifically, the sealing sleeve 900 includes a sleeve portion 910 and an abutment portion 920. The sleeve portion 910 is cylindrical and is fitted between the connecting pipe 800 and the inlet pipe 700. The abutment portion 920 is formed on the outer periphery of the top end of the sleeve portion 910 and abuts axially between the first flange 230 and the inlet pipe 700. For details, please refer to [link / reference]. Figure 7 A slot 921 is formed on the side of the contact portion 920 facing the liquid inlet tube 700, and the top end of the liquid inlet tube 700 is inserted into the slot 921.

[0074] In addition, please refer to Figure 9 The inner wall of the installation channel 260 is formed with a stepped surface 261, and the top surface of the connecting pipe 800 abuts against the stepped surface 261. The inner wall of the sleeve part 910 is provided with a protruding strip 930, which abuts against the outer peripheral surface of the bottom end of the connecting pipe 800, thereby forming an axial limit for the connecting pipe 800 through the stepped surface 261 and the protruding strip 930.

[0075] In some embodiments, please refer to Figure 9A mounting groove 410 is formed on the side of the seal 400 facing the bottom cover 300. The mounting groove 410 communicates with the airflow chamber 1032. A one-way ventilation valve 600 is installed in the mounting groove 410, thereby forming a communication between the ventilation channel 102 and the airflow chamber 1032. Furthermore, a connecting hole 420 is formed on the side of the seal 400 away from the bottom cover 300. The connecting hole 420 communicates with the mounting groove 410, thereby forming a communication between the ventilation channel 102 and the second liquid chamber 1012. It is understood that in other embodiments of this application, the ventilation channel 102 can also be formed on the seal 400, that is, by forming a curved and extending groove in or around the seal 400 to form the ventilation channel 102.

[0076] In one embodiment, the sealing member 400 has a protruding ring 430 facing the first liquid chamber 1011, and the bottom end of the liquid guide tube is inserted into the protruding ring 430 to form a sealed connection between the liquid guide tube and the connection port 1033.

[0077] In some embodiments, please refer to Figure 4 and Figure 9 The atomizer 1 also includes a liquid injection mechanism 1000. The side wall of the second liquid chamber 1012 has a mounting port 221, and the liquid injection mechanism 1000 is installed at the mounting port 221. During liquid injection, the liquid injection mechanism 1000 is connected to an external liquid storage container so that the atomizing medium is injected into the second liquid chamber 1012 through the liquid injection mechanism 1000 until the first liquid chamber 1011 and the second liquid chamber 1012 are filled with the atomizing medium.

[0078] For details, please refer to Figure 10An installation port 221 is formed in the side plate 220. The liquid injection mechanism 1000 includes a fixing member 1100, a liquid injection tube 1200, and an elastic member 1300. The fixing member 1100 is installed in the installation port 221. The liquid injection tube 1200 is movably installed in the inner cavity of the fixing member 1100, and the liquid injection tube 1200 extends at least partially into the second liquid chamber 1012. An injection port 1201 is formed on the side wall of the liquid injection tube 1200. The elastic member 1300 is sleeved on the outside of the liquid injection tube 1200 and abuts against the liquid injection tube 1200 and the fixing member 1100. When the elastic element 1300 is in its natural extension / retraction state, the injection port 1201 is located within the fixing element 1100, and the injection port 1201 is not connected to the second liquid chamber 1012. When the injection pipe 1200 is connected to the external liquid storage container, the injection pipe 1200 is pushed towards the second liquid chamber 1012, causing the injection port 1201 to be pushed out from the fixing element 1100 and connected to the second liquid chamber 1012. This allows the injection of atomized medium into the second liquid chamber 1012 through the injection pipe 1200 and the injection port 1201, while the elastic element 1300 is in a compressed state. After injection is complete, the external force acting on the injection pipe 1200 disappears, and the injection pipe 1200 resets under the action of the elastic element 1300, thereby causing the injection port 1201 to retract into the fixing element 1100.

[0079] In addition, please see Figure 10 A sealing ring 1400 is abutted between the inner end of the injection tube 1200 and the fixing member 1100. The sealing ring 1400 forms a sealed connection between the injection tube 1200 and the fixing member 1100, thereby preventing the atomizing medium in the second liquid chamber 1012 from leaking from the gap between the fixing member 1100 and the injection tube 1200.

[0080] 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.
