[0003] However, during transportation and storage, factors such as changes in air pressure, temperature, and mechanical vibration can cause the atomizing liquid to leak out of the atomizing chamber, leading to leakage problems in the atomizer. Utility Model Content

[0004] In view of this, embodiments of this application aim to provide a liquid storage component, atomizer, atomizing component, and aerosol generating device that can effectively alleviate the problem of liquid leakage.

[0005] To achieve the above objectives, a first aspect of this application provides a liquid storage assembly for use in conjunction with an atomizer having a second liquid storage chamber, the liquid storage assembly comprising:

[0015] The second housing has a liquid outlet communicating with the second liquid storage chamber. The atomizer also includes a seal disposed at the liquid outlet. The seal is punctured by the liquid storage assembly to communicate the second liquid storage chamber with the first liquid storage chamber.

[0016] A third aspect of this application provides an atomizing component, including:

[0017] A liquid storage assembly, the liquid storage assembly including a first housing having a first liquid storage chamber;

[0018] An atomizer includes an atomizing core and a second housing having a second liquid storage chamber. The atomizer is assembled with the liquid storage assembly so that the second liquid storage chamber is in communication with the first liquid storage chamber. The atomizing core is disposed in the second housing and is in fluid communication with the second liquid storage chamber to heat and atomize the atomized liquid from the first liquid storage chamber.

[0019] The liquid storage assembly further includes a first vent valve having a first connection port. The first vent valve is located at the first liquid storage chamber. When the pressure inside the first liquid storage chamber is greater than the external pressure, the first vent valve, under the action of the pressure inside the first liquid storage chamber, opens the first connection port to connect the first liquid storage chamber with the outside; and / or,

[0020] The atomizer also includes a second ventilation valve, which has a second connection port. The second ventilation valve is located at the second liquid storage chamber. When the external pressure is greater than the pressure inside the second liquid storage chamber, the second ventilation valve opens the second connection port under the action of the external pressure, so that the second liquid storage chamber is connected to the outside.

[0021] In some embodiments, the first housing has an air outlet in fluid communication with the atomizing core, and the air outlet and the second liquid storage chamber are located on opposite sides of the first liquid storage chamber along a first direction of the atomizing assembly.

[0022] In some embodiments, the portion of the second ventilation valve having at least the second communication port is located within the second liquid storage chamber; the second communication port and the air outlet have a first distance along the first direction; the atomizing core and the air outlet have a second distance along the first direction; and / or,

[0023] The second communication port faces the first liquid storage cavity and avoids the communication position between the first liquid storage cavity and the second liquid storage cavity; and / or,

[0024] One of the liquid storage assembly and the atomizer communicates with the first liquid storage chamber by piercing the other.

[0025] In some embodiments, the second liquid storage cavity has a first end and a second end opposite to each other along a second direction, wherein the second direction is orthogonal to the first direction;

[0026] The first end is connected to the first liquid storage cavity, and the connection point between the first end and the first liquid storage cavity is located on the side of the second end closer to the first liquid storage cavity along the first direction; and / or,

[0027] The second end is in fluid communication with the atomizing core.

[0028] In some embodiments, the first housing has a mounting groove, and the first ventilation valve is disposed within the mounting groove; and / or,

[0029] The liquid storage assembly further includes a protective cover over the first ventilation valve, the protective cover having a clearance opening that avoids the first communication port, the clearance opening being connected to the outside through the first communication port; and / or,

[0030] The atomizing assembly includes a first ventilation valve and a second ventilation valve, wherein the external pressure connected to the second connection port of the second ventilation valve is not less than the pressure inside the first liquid storage chamber connected to the first connection port of the first ventilation valve; and / or,

[0031] The liquid storage assembly and the atomizer are detachably connected; and / or, the first ventilation valve has a first flow channel communicating with the first communication port, wherein when the pressure on the outer surface of the first ventilation valve is less than the pressure in the first flow channel, the first ventilation valve opens the first communication port by elastic deformation; and when the pressure on the outer surface of the first ventilation valve is not less than the pressure in the first flow channel, the first ventilation valve closes the first communication port by restoring its elastic deformation; and / or

[0032] The second air exchange valve has a second flow channel communicating with the second communication port. When the pressure on the outer surface of the second air exchange valve is less than the pressure in the second flow channel, the second air exchange valve opens the second communication port by elastic deformation; when the pressure on the outer surface of the second air exchange valve is not less than the pressure in the second flow channel, the second air exchange valve closes the second communication port by restoring elastic deformation.

[0033] A fourth aspect of this application provides an aerosol generating apparatus, including a power supply component and the aforementioned atomizing component, wherein the power supply component is electrically connected to the atomizer.

[0034] This application provides a liquid storage component, an atomizer, an atomizing component, and an aerosol generating device. The atomizing component of this application includes a liquid storage component and an atomizer. These are two independent components that need to be assembled for use. Assembly is only required when needed, thus preventing leakage of the atomized liquid from the liquid storage component during transportation and / or storage. Furthermore, taking the liquid storage component of the atomizing component as an example, if the pressure inside the first liquid storage chamber is greater than the external pressure, the first venting valve opens the first connection port under the pressure inside the first liquid storage chamber, connecting the first liquid storage chamber to the outside and discharging some air from the first liquid storage chamber to the outside. This reduces the pressure in the first liquid storage chamber, preventing a large amount of atomized liquid from flowing into the second liquid storage chamber and leaking from the atomizing core. Conversely, if the pressure inside the first liquid storage chamber is less than the external pressure, the first venting valve closes the first connection port to isolate the first liquid storage chamber from the outside, preventing leakage of the atomized liquid from the first liquid storage chamber. Taking the atomizer of the atomizing component, which also includes a second ventilation valve 22, as an example, when the external pressure is greater than the pressure inside the second liquid storage chamber, the second ventilation valve opens the second connecting port under the action of the external pressure, so that the second liquid storage chamber is connected to the outside. Outside air can enter the first liquid storage chamber through the second liquid storage chamber, thereby realizing air intake of the first liquid storage chamber. In this process, the atomized liquid cannot overcome the pressure difference to flow out from the second connecting port. Therefore, even if the second connecting port connects the second liquid storage chamber to the outside, the atomized liquid cannot flow out from the second connecting port. When the pressure in the second liquid storage chamber is greater than the external pressure, the atomized liquid cannot flow out from the second connecting port because the second connecting port is closed. When the atomizing component is equipped with both a first venting valve and a second venting valve, when the pressure inside the first liquid storage chamber is greater than the external pressure, the second venting valve closes the second connection port to isolate the second liquid storage chamber from the outside, preventing leakage of the atomized liquid. Meanwhile, the first venting valve connects to the first connection port, allowing some air in the first liquid storage chamber to escape through the first connection port, thereby reducing the pressure inside the first liquid storage chamber and bringing it closer to the external pressure, further reducing the possibility of atomized liquid leakage. Thus, the first and second venting valves work together to further improve the leak-proof effect of the atomizing component. Therefore, the atomizing component in this embodiment can effectively alleviate the leakage problem. Attached Figure Description

[0044] In the description of the embodiments in this application, it should be noted that the terms "first direction" and "second direction" are based on the appended... Figure 3 The orientation or positional relationship shown is merely for the convenience of describing the embodiments of this application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the embodiments of this application.

[0045] This application provides an atomizing component 100. Please refer to [link / reference]. Figures 1 to 7 The atomizing assembly 100 includes a liquid storage assembly 10 and an atomizer 20.

[0046] The liquid storage assembly 10 includes a first housing 11 having a first liquid storage chamber 11a. The atomizer 20 includes an atomizing core 23 and a second housing 21 having a second liquid storage chamber 21a. The atomizer 20 is assembled with the liquid storage assembly 10 such that the second liquid storage chamber 21a communicates with the first liquid storage chamber 11a. The atomizing core 23 is disposed within the second housing 21 and is in fluid communication with the second liquid storage chamber 21a to heat and atomize the atomized liquid from the first liquid storage chamber 11a.

[0047] The first liquid storage chamber 11a is used to store the atomizing liquid. A certain cavity (i.e., a space not filled by the atomizing liquid) is formed above the atomizing liquid in the first liquid storage chamber 11a. The gas pressure in this cavity is the pressure in the first liquid storage chamber 11a. As the atomizing liquid gradually flows out of the first liquid storage chamber 11a, the volume of the cavity in the first liquid storage chamber 11a gradually increases.

[0048] The second liquid storage chamber 21a is used to connect the first liquid storage chamber 11a and the atomizing core 23 in fluid communication, guiding the atomized liquid in the first liquid storage chamber 11a to flow to the atomizing core 23, so that the atomizing core 23 heats and atomizes the atomized liquid to generate an aerosol. In some embodiments, the atomized liquid does not completely fill the second liquid storage chamber 21a, that is, a certain cavity is also formed above the atomized liquid in the second liquid storage chamber 21a, and the gas pressure in this cavity is the pressure in the second liquid storage chamber 21a. In other embodiments, the atomized liquid can completely fill the second liquid storage chamber 21a. In this case, the pressure in the second liquid storage chamber 21a is the hydraulic pressure of the atomized liquid.

[0049] It should be noted that the liquid reservoir 10 and the atomizer 20 need to be assembled for use. That is, the liquid reservoir 10 and the atomizer 20 are two separate, independent components. Before they are assembled, the first liquid reservoir 11a and the second liquid reservoir 21a are not connected, and the atomized liquid in the first liquid reservoir 11a cannot flow into the second liquid reservoir 21a. The liquid reservoir 10 and the atomizer 20 can be assembled before sale, or the user can purchase them separately and assemble them themselves. In the embodiment where the liquid reservoir 10 and the atomizer 20 are assembled before sale, the liquid reservoir 10 and the atomizer 20 can be non-detachably connected after assembly; that is, the user cannot separate the liquid reservoir 10 and the atomizer 20. In the embodiment where the user purchases the reservoir component 10 and the atomizer 20 separately and then assembles them themselves, after the atomizing liquid in the reservoir component 10 is consumed, the user can separate the reservoir component 10 from the atomizer 20 (i.e., the reservoir component 10 and the atomizer 20 are detachably connected), and then assemble the newly purchased reservoir component 10 with the original atomizer 20. Whether the atomizer component 100 is assembled and then sold, or purchased separately and assembled by the user, since the reservoir component 10 and the atomizer 20 are two separate and independent components during transportation and / or storage, the leakage of atomizing liquid from the atomizer in the reservoir component 10 due to factors such as changes in air pressure, temperature, and mechanical vibration during transportation and / or storage can be effectively avoided.

[0050] The assembly method of the liquid storage component 10 and the atomizer 20 of the atomizing component 100 is not limited. For example, one of the liquid storage component 10 and the atomizer 20 is punctured to make the second liquid storage chamber 21a communicate with the first liquid storage chamber 11a.

[0051] This application provides a liquid storage component 10. Please refer to [link / reference]. Figure 2 , Figure 3 , Figure 5 and Figure 6 The liquid storage assembly 10 also includes a first ventilation valve 12, which is disposed at the first liquid storage chamber 11a. The first ventilation valve 12 has a first communication port 12a. When the pressure in the first liquid storage chamber 11a is greater than the external pressure, the first ventilation valve 12 opens the first communication port 12a under the action of the pressure in the first liquid storage chamber 11a, so that the first liquid storage chamber 11a is connected to the outside.

[0052] The first venting valve 12 balances the pressure between the first liquid storage chamber 11a and the outside environment, thereby reducing the pressure difference between the first liquid storage chamber 11a and the outside environment and preventing leakage of the atomized liquid. Whether before or after assembly of the liquid storage assembly 10 and the atomizer 20, when the pressure inside the first liquid storage chamber 11a is greater than the external pressure, the first venting valve 12 can open the first connecting port 12a to allow some air in the first liquid storage chamber 11a to be discharged to the outside environment, thus reducing the pressure in the first liquid storage chamber 11a. Conversely, when the pressure inside the first liquid storage chamber 11a is less than the external pressure, the first venting valve 12 closes the first connecting port 12a to isolate the first liquid storage chamber 11a from the outside environment, preventing leakage of the atomized liquid in the first liquid storage chamber 11a. Therefore, the first venting valve 12 has a good anti-leakage effect.

[0053] This application also provides an atomizer 20, please refer to... Figures 2 to 4 The atomizer 20 also includes a second ventilation valve 22, which is located at the second liquid storage chamber 21a. The second ventilation valve 22 has a second connection port 22a. When the external pressure is greater than the pressure in the second liquid storage chamber 21a, the second ventilation valve 22 opens the second connection port 22a under the action of the external pressure, so that the second liquid storage chamber 21a is connected to the outside.

[0054] The second vent valve 22 is used to balance the pressure difference between the second liquid storage chamber 21a and the outside environment, while preventing the atomized liquid in the second liquid storage chamber 21a from leaking out of the second housing 21. When the external pressure is greater than the pressure inside the second liquid storage chamber 21a, the second vent valve 22 opens the second connecting port 22a, allowing outside air to enter the second liquid storage chamber 21a. When the external pressure is less than the pressure inside the second liquid storage chamber 21a, the second vent valve 22 closes the second connecting port 22a, isolating the second liquid storage chamber 21a from the outside environment, thereby preventing atomized liquid leakage.

[0055] Taking the assembly of the liquid storage component 10 and the atomizer 20 as an example, in the initial state, the pressure of the first liquid storage chamber 11a, the second liquid storage chamber 21a, and the external environment is roughly balanced. Simultaneously, the second liquid storage chamber 21a contains a certain amount of atomized liquid, forming a stable "liquid storage-liquid guiding" preparatory state. When the user inhales, the pressure on one side of the atomizing core 23 decreases rapidly (forming a negative pressure, i.e., lower than the external atmospheric pressure), causing the pressure in the second liquid storage chamber 21a to decrease accordingly, falling below the pressure in the first liquid storage chamber 11a. Under the pressure difference, the atomized liquid in the first liquid storage chamber 11a flows through the second liquid storage chamber 21a to the atomizing core 23 to replenish the atomized liquid consumed by the heating of the atomizing core 23. At this time, the amount of atomized liquid in the first liquid storage chamber 11a decreases due to the inflow into the second liquid storage chamber 21a, resulting in an increase in the cavity volume within the first liquid storage chamber 11a. The pressure in the first liquid storage chamber 11a decreases and approaches the pressure in the second liquid storage chamber. When the pressure in chamber 21a reaches equilibrium, meaning the external pressure is greater than the pressure in both the second and first liquid storage chambers 21a, the second ventilation valve 22 opens the second connection port 22a under the pressure difference. Outside air enters the second liquid storage chamber 21a through the second connection port 22a, causing the pressure in the second liquid storage chamber 21a to rise. The pressure in the second liquid storage chamber 21a is slightly higher than the pressure in the first liquid storage chamber 11a. Some of the air in the second liquid storage chamber 21a enters the cavity within the first liquid storage chamber 11a, further increasing the pressure in the first liquid storage chamber 11a. The pressure in the second liquid storage chamber 21a then decreases again as the user inhales. This pressure change process continues cyclically during the user's inhalation.

[0056] Since the pressure on the atomizing liquid in the second storage chamber 21a is the same as the pressure inside the second storage chamber 21a, when the pressure inside the second storage chamber 21a is lower than the external pressure, the atomizing liquid cannot overcome the pressure difference to flow out from the second connecting port 22a. Therefore, even if the second connecting port 22a connects the second storage chamber 21a to the outside to allow air to enter the second storage chamber 21a, the atomizing liquid cannot flow out from the second connecting port 22a. Conversely, when the pressure in the second storage chamber 21a is greater than the external pressure, the atomizing liquid cannot flow out from the second connecting port 22a because it is closed. Thus, the second vent valve 22 has a good leak-proof effect.

[0057] It should be noted that the atomizing component 100 in this application embodiment may only have the first air exchange valve 12 and not the second air exchange valve 22, or it may only have the second air exchange valve 22 and not the first air exchange valve 12, or it may have both the first air exchange valve 12 and the second air exchange valve 22.

[0058] Please see Figure 3In an embodiment where the atomizing component 100 is provided with both a first ventilation valve 12 and a second ventilation valve 22, the external pressure connected to the second communication port 22a of the second ventilation valve 22 is not less than the pressure in the first liquid storage chamber 11a connected to the first communication port 12a of the first ventilation valve 12.

[0059] The first ventilation valve 12 is used for exhaust, and the second ventilation valve 22 is used for intake. When the external pressure is greater than the pressure in the second liquid storage chamber 21a, the second ventilation valve 22 allows outside air to enter the second liquid storage chamber 21a by opening its second connection port 22a, thereby further increasing the pressure in the first liquid storage chamber 11a and achieving air intake during the suction process. During this process, the first ventilation valve 12 closes its first connection port 12a because the external pressure is greater than the pressure in the first liquid storage chamber 11a. When the pressure in the first liquid storage chamber 11a is greater than the external pressure, the first ventilation valve 12 allows some of the air in the first liquid storage chamber 11a to be discharged to the outside by opening its first connection port 12a. During this process, the second ventilation valve 22 closes its second connection port 22a because the pressure in the second liquid storage chamber 21a is greater than the external pressure.

[0060] For ease of description, the external pressure that allows the second connection port 22a of the second ventilation valve 22 to be open is called the second pressure value, and the pressure in the first liquid storage chamber 11a that allows the first connection port 12a of the first ventilation valve 12 to be open is called the first pressure value. The second pressure value can be equal to or greater than the first pressure value.

[0061] When the pressure inside the first liquid storage chamber 11a is greater than the external pressure, the second vent valve 22 closes the second connecting port 22a to isolate the second liquid storage chamber 21a from the outside, preventing leakage of the atomized liquid. Meanwhile, the first vent valve 12 connects to the first connecting port 12a, allowing some air inside the first liquid storage chamber 11a to escape through the first connecting port 12a, thereby reducing the pressure inside the first liquid storage chamber 11a and bringing it closer to the external pressure, further reducing the possibility of atomized liquid leakage. Since the second pressure value is not less than the first pressure value, some air inside the first liquid storage chamber 11a can be discharged more smoothly, further improving the leak-proof effect.

[0062] This application also provides an aerosol generating device; please refer to [link / reference]. Figures 1 to 7 The aerosol generating device includes a power supply component 200 and an atomizing component 100 provided in any embodiment of this application. The power supply component 200 is electrically connected to the atomizer 20.

[0063] Aerosol generating devices are used to produce aerosols for users to inhale or for medical, cosmetic, and other applications. The power supply assembly 200 works in conjunction with the atomizing assembly 100 to power the atomizer 20 and control its operating status. The power supply assembly 200 typically includes a battery for powering the atomizer 20 and control components for controlling the atomizer's heating.

[0064] In related technologies, the atomizing fluid is stored in the reservoir of the atomizer. During transportation and storage, factors such as changes in air pressure, temperature, and mechanical vibration can easily cause the atomizing fluid to leak from the atomizer core. For example, when the atomizer moves from a high-pressure environment to a low-pressure environment, the external pressure drops while the pressure in the reservoir remains relatively constant. This results in the pressure in the reservoir being greater than the external pressure, causing a large amount of atomizing fluid to rush towards the atomizer core under the influence of the pressure difference, leading to leakage.

[0065] The atomizing component 100 in this application embodiment includes a liquid storage component 10 and an atomizer 20. The liquid storage component 10 and the atomizer 20 are two independent components that need to be assembled for use. They can be assembled when needed, thereby preventing leakage of the atomizing liquid in the liquid storage component 10 during transportation and / or storage. In addition, taking the liquid storage component 10 of the atomizing component 100 as an example, which also includes a first ventilation valve 12, when the pressure inside the first liquid storage chamber 11a is greater than the external pressure, the first ventilation valve 12 opens the first connecting port 12a under the action of the pressure inside the first liquid storage chamber 11a, so that the first liquid storage chamber 11a is connected to the outside, and some of the air inside the first liquid storage chamber 11a is discharged to the outside, thereby reducing the pressure inside the first liquid storage chamber 11a and preventing a large amount of atomized liquid from flowing into the second liquid storage chamber 21a and leaking out from the atomizing core 23. When the pressure inside the first liquid storage chamber 11a is less than the external pressure, the first ventilation valve 12 closes the first connecting port 12a to isolate the first liquid storage chamber 11a from the outside and prevent the atomized liquid inside the first liquid storage chamber 11a from leaking out. Taking the atomizer 20 of the atomizing assembly 100, which also includes a second ventilation valve 22, as an example, when the external pressure is greater than the pressure inside the second liquid storage chamber 21a, the second ventilation valve 22 opens the second connecting port 22a under the action of the external pressure, so that the second liquid storage chamber 21a is connected to the outside. Outside air can enter the first liquid storage chamber 11a through the second liquid storage chamber 21a, thereby realizing air intake of the first liquid storage chamber 11a. In this process, the atomized liquid cannot overcome the pressure difference to flow out from the second connecting port 22a. Therefore, even if the second connecting port 22a connects the second liquid storage chamber 21a to the outside, the atomized liquid cannot flow out from the second connecting port 22a. When the pressure in the second liquid storage chamber 21a is greater than the external pressure, the atomized liquid cannot flow out from the second connecting port 22a because the second connecting port 22a is closed. When the atomizing assembly 100 is equipped with both a first ventilation valve 12 and a second ventilation valve 22, when the pressure inside the first liquid storage chamber 11a is greater than the external pressure, the second ventilation valve 22 closes the second connecting port 22a to isolate the second liquid storage chamber 21a from the outside, preventing leakage of the atomized liquid. Meanwhile, the first ventilation valve 12 connects to the first connecting port 12a, allowing some air inside the first liquid storage chamber 11a to be discharged through the first connecting port 12a, thereby reducing the pressure inside the first liquid storage chamber 11a and bringing it closer to the external pressure, further reducing the possibility of atomized liquid leakage. Thus, the first ventilation valve 12 and the second ventilation valve 22 work together to further improve the leak-proof effect of the atomizing assembly 100. Therefore, the atomizing assembly 100 in this embodiment can effectively alleviate the leakage problem.

[0066] In some embodiments, please refer to Figure 3 and Figure 4The first housing 11 has a liquid outlet 11b that communicates with the first liquid storage chamber 11a. The liquid storage assembly 10 may also include a seal 13 disposed at the liquid outlet 11b. The seal 13 is pierced by the atomizer 20 to communicate with the first liquid storage chamber 11a and the second liquid storage chamber 21a.

[0067] The outlet 11b is the outlet from which the atomized liquid flows out of the first liquid storage chamber 11a. The seal 13 is used to seal the outlet 11b to prevent the atomized liquid in the first liquid storage chamber 11a from leaking out of the outlet 11b before assembly.

[0068] The seal 13 being punctured by the atomizer 20 means that during the assembly of the liquid storage assembly 10 and the atomizer 20, the seal 13 is damaged by the structure of the atomizer 20, thereby allowing the atomized liquid to enter the second liquid storage chamber 21a through the liquid outlet 11b, which can improve the assembly efficiency of the liquid storage assembly 10 and the atomizer 20.

[0069] In other embodiments, the first housing 11 includes a piercing member with a communicating channel, which pierces the atomizer 20 to communicate the first liquid storage chamber 11a with the second liquid storage chamber 21a. That is, the liquid storage assembly 10 pierces the atomizer 20, thereby allowing the atomized liquid to enter the second liquid storage chamber 21a.

[0070] In some embodiments, please refer to Figure 3 and Figure 4 The second housing 21 includes a piercing member 211 having a communicating channel 211a. The piercing member 211 pierces the liquid storage assembly 10 so that the second liquid storage chamber 21a communicates with the first liquid storage chamber 11a through the communicating channel 211a.

[0071] The piercing element 211 is used to pierce the liquid storage assembly 10 and introduce the atomized liquid into the second liquid storage chamber 21a.

[0072] In an embodiment where the liquid storage assembly 10 has a seal 13 and an outlet 11b, the piercing member 211 pierces the seal 13 so that a portion of the structure extends into the first liquid storage chamber 11a through the outlet 11b, thereby introducing the atomizing liquid into the second liquid storage chamber 21a, which can improve the assembly stability of the liquid storage assembly 10 and the atomizer 20.

[0073] In other embodiments, the second housing 21 has a liquid outlet communicating with the second liquid storage chamber, and the atomizer 20 further includes a seal disposed at the liquid outlet. The seal is pierced by the liquid storage assembly 10 to communicate the second liquid storage chamber 21a with the first liquid storage chamber 11a. That is, the liquid storage assembly 10 pierces the atomizer 20, thereby allowing the atomized liquid to enter the second liquid storage chamber 21a.

[0074] In some embodiments, please refer to Figures 1 to 4The first housing 11 has an air outlet 11c that is in fluid communication with the atomizing core 23. The air outlet 11c and the second liquid storage chamber 21a are located on opposite sides of the first liquid storage chamber 11a along the first direction of the atomizing assembly 100.

[0075] The air outlet 11c refers to the outlet on the first housing 11 from which the aerosol flows into the user's mouth. In other words, when the user inhales the aerosol, the second liquid storage chamber 21a is located below the first liquid storage chamber 11a. This allows gravity to enhance the delivery of the atomizing liquid to the atomizing core 23, which, together with the pressure difference between the first and second liquid storage chambers 11a, improves the stability and efficiency of the liquid delivery, ensuring that the atomizing core 23 can continuously receive atomizing liquid.

[0076] In some embodiments, please refer to Figures 1 to 4 The second vent valve 22 has at least one portion with a second connecting port 22a located inside the second liquid storage chamber 21a. That is, a portion of the structure of the second vent valve 22 extends into the second liquid storage chamber 21a, and the second connecting port 22a is located inside the second liquid storage chamber 21a. This allows outside air to directly enter the second liquid storage chamber 21a and then the first liquid storage chamber 11a when the external pressure is greater than the pressure inside the lower first liquid storage chamber 11a. At the same time, when the external pressure is less than the pressure inside the first liquid storage chamber 11a, the pressure difference can be used to keep the second connecting port 22a closed, preventing the atomized liquid in the first liquid storage chamber 11a from leaking through the second connecting port 22a.

[0077] Further, please refer to Figure 3 The second connecting port 22a and the air outlet 11c have a first spacing H1 along the first direction, and the atomizing core 23 and the air outlet 11c have a second spacing H2 along the first direction. The first spacing H1 may be smaller than the second spacing H2.

[0078] In other words, during use, the height of the second connecting port 22a is higher than the height of the atomizing core 23. When the atomized liquid flows from the first liquid storage chamber 11a to the atomizing core 23, the higher height of the second connecting port 22a prevents the atomized liquid from overflowing from the second connecting port 22a under the combined effects of gravity and pressure, thereby reducing leakage. Simultaneously, it also reduces the possibility of the second connecting port 22a being blocked by the atomized liquid, ensuring smooth air exchange.

[0079] Please see Figures 1 to 4 The distances between the first connecting port 12a and the second connecting port 22a and the air outlet 11c are both less than the distances between the atomizing core 23 and the air outlet 11c along the first direction.

[0080] For example, please refer to Figure 3 and Figure 4The second connecting port 22a can face the first liquid storage chamber 11a, avoiding the connection between the first liquid storage chamber 11a and the second liquid storage chamber 21a. In other words, when the atomized liquid in the first liquid storage chamber 11a flows into the second liquid storage chamber 21a, it will not flow directly to the second connecting port 22a. This can prevent the atomized liquid from leaking out of the second connecting port 22a and further improve the anti-leakage effect.

[0081] In some embodiments, please refer to Figure 3 and Figure 4 The second liquid storage cavity 21a has a first end 21a1 and a second end 21a2 that are opposite each other along a second direction, wherein the second direction is orthogonal to the first direction.

[0082] The first end 21a1 is connected to the first liquid storage chamber 11a, and the connection position between the first end 21a1 and the first liquid storage chamber 11a is located on the side of the second liquid storage chamber 21a close to the first liquid storage chamber 11a along the first direction. This simplifies the flow path of the atomizing liquid, allowing the atomizing liquid to flow more smoothly to the atomizing core 23 under the action of pressure and gravity.

[0083] For example, please refer to Figure 3 and Figure 4 The second end 21a2 can be in fluid communication with the atomizing core 23. That is, the atomizing core 23 is located on one side of the second liquid storage chamber 21a along the second direction. The atomized liquid in the first liquid storage chamber 11a enters the second end 21a2 along the first end 21a1 of the second liquid storage chamber 21a, and can flow directly to the atomizing core 23 to ensure stable liquid supply.

[0084] For example, please refer to Figure 3 and Figure 4 The first housing 11 also has an air passage 11d that communicates with the air outlet 11c. The air passage 11d is in fluid communication with the atomizing core 23 so that the aerosol generated by the atomizing core 23 heating and atomizing the atomizing liquid flows into the air passage 11d. When the external airflow flows along the air passage 11d, it carries the aerosol to the air outlet 11c so that it reaches the user's mouth.

[0085] Please continue reading. Figure 3 and Figure 4 The second liquid storage chamber 21a and the air passage 11d are located on opposite sides of the atomizing core 23 along the second direction, which allows the aerosol generated by the atomizing core 23 to be directly released into the air passage 11d, thereby reducing the airflow resistance in the air passage 11d, reducing the generation of condensate in the air passage 11d, and reducing aerosol loss.

[0086] More preferably, please refer to Figure 3 and Figure 4The first liquid storage chambers 11a are all surrounding the outer periphery of the air passage 11d and are separated from the air passage 11d, thereby improving the compactness of the internal space of the first housing 11 and increasing the size of the first liquid storage chambers 11a.

[0087] In some embodiments, please refer to Figure 3 and Figure 5 The first housing 11 may have a mounting groove (not shown in the figure), and the first ventilation valve 12 is disposed in the mounting groove.

[0088] The mounting slots are connected to the outside and the first liquid storage chamber 11a, respectively, and are used to install the first ventilation valve 12 to protect and fix the first ventilation valve 12.

[0089] Please see Figure 3 and Figure 5 The mounting slot is located on the side of the first liquid storage chamber 11a away from the second liquid storage chamber 21a along the first direction. That is, the first air exchange valve 12 can be set on the side of the first liquid storage chamber 11a away from the second liquid storage chamber 21a along the first direction. In other words, the setting height of the first air exchange valve 12 is higher than the setting height of the second air exchange valve 22, so as to ensure that when the atomizer is used, the area below the first air exchange valve 12 is the cavity in the first liquid storage chamber 11a, and not the atomized liquid. This can prevent the atomized liquid from being sprayed out from the first connecting port 12a under pressure when the first air exchange valve 12 is venting.

[0090] Please see Figure 3 , Figure 5 and Figure 7 The atomizer also includes a protective cover 30 covering the first ventilation valve 12. The protective cover 30 has a clearance opening 30a that avoids the first communication port 12a. The clearance opening 30a is connected to the outside through the first communication port 12a.

[0091] In other words, the protective cover 30 is at least positioned above the first connecting port 12a to prevent foreign objects from entering the first liquid storage chamber 11a through the first connecting port 12a and affecting the normal operation of the atomizer, while also preventing leakage.

[0092] For the embodiment where the first ventilation valve 12 is located in the mounting slot, please refer to [link to embodiment]. Figure 3 , Figure 5 and Figure 7 The protective cover 30 is also installed in the mounting groove to further improve the protection effect of the first ventilation valve 12.

[0093] More preferably, please refer to Figure 3 , Figure 5 and Figure 7The protective cover 30 includes a cover body 31 and a plurality of protrusions 32 extending from the cover body 31. The plurality of protrusions 32 are spaced apart along the periphery of the cover body 31. The cover body 31 also has a receiving cavity 30b and a clearance opening 30a communicating with the receiving cavity 30b. When the protective cover 30 is placed in the mounting groove, at least a portion of the structure of the first vent valve 12 is located within the receiving cavity 30b of the protective cover 30. The plurality of protrusions 32 are in interference contact with the sidewall of the mounting groove to fix the protective cover 30 in the mounting groove, while the cover body 31 is spaced apart from the groove wall of the mounting groove. When the first vent valve 12 is venting, air enters the receiving cavity 30b from the first communication opening 12a, and enters the gap between the cover body 31 and the sidewall of the mounting groove through the clearance opening 30a, and finally enters the outside.

[0094] In other embodiments, the protective cover 30 may also be partially located within the mounting groove.

[0095] In some embodiments, please refer to Figure 3 and Figure 4 The first ventilation valve 12 may have a first flow channel 12b communicating with the first connection port 12a. When the pressure on the outer surface of the first ventilation valve 12 is less than the pressure inside the first flow channel 12b, the first ventilation valve 12 opens the first connection port 12a by generating elastic deformation. When the pressure on the outer surface of the first ventilation valve 12 is not less than the pressure inside the first flow channel 12b, the first ventilation valve 12 closes the first connection port 12a by restoring its elastic deformation.

[0096] In other words, in the initial state (when the first ventilation valve 12 is not under force), the first connection port 12a is closed. When a pressure difference occurs between the first flow channel 12b and the outer surface of the first ventilation valve 12, the first ventilation valve 12 opens the first connection port 12a under the action of the pressure difference. In other embodiments, in the initial state, the first connection port 12a may also be open. When a pressure difference occurs between the first flow channel 12b and the outer surface of the first ventilation valve 12, the first ventilation valve 12 closes the first connection port 12a under the action of the pressure difference.

[0097] For the first venting valve 12, since the first flow channel 12b is connected to the first liquid storage chamber 11a, and the outer surface of the first venting valve 12 is connected to the outside atmosphere, the pressure inside the first flow channel 12b is the pressure inside the first liquid storage chamber 11a, and the pressure on the outer surface of the first venting valve 12 is the outside atmospheric pressure. When the pressure of the outside atmosphere is less than the pressure inside the first liquid storage chamber 11a, the first venting valve 12 undergoes elastic deformation under the action of the pressure difference to open the first connecting port 12a, thereby connecting the first liquid storage chamber 11a and the outside atmosphere, allowing some air to be discharged from the first liquid storage chamber 11a and reducing the pressure inside the first liquid storage chamber 11a. Conversely, when the pressure of the outside atmosphere is not less than the pressure inside the first liquid storage chamber 11a, the first venting valve 12 restores its elastic deformation to close the first connecting port 12a, thereby isolating the first liquid storage chamber 11a from the outside atmosphere.

[0098] It can be seen that, through the above-mentioned opening and closing mechanism, the first vent valve 12 can dynamically balance the pressure of the first liquid storage chamber 11a, reduce the pressure of the first liquid storage chamber 11a in time by venting, and prevent leakage by sealing the first connecting port 12a when the pressure of the first liquid storage chamber 11a is normal.

[0099] The opening and closing mechanism of the second ventilation valve 22 is similar to that of the first ventilation valve. For example, please refer to [link to relevant documentation]. Figure 3 The second ventilation valve 22 has a second flow channel 22b communicating with the second connection port 22a. When the pressure on the outer surface of the second ventilation valve 22 is less than the pressure inside the second flow channel 22b, the second ventilation valve 22 opens the second connection port 22a by elastic deformation. When the pressure on the outer surface of the second ventilation valve 22 is not less than the pressure inside the second flow channel 22b, the second ventilation valve 22 closes the second connection port 22a by restoring its elastic deformation.

[0100] Since the second flow channel 22b is connected to the outside atmosphere, and the outer surface of the second vent valve 22 is connected to the second liquid storage chamber 21a, the pressure inside the second flow channel 22b is the same as the pressure of the outside atmosphere, and the pressure on the outer surface of the second vent valve 22 is the same as the pressure inside the second liquid storage chamber 21a. When the pressure inside the second liquid storage chamber 21a is less than the pressure of the outside atmosphere, the second vent valve 22 undergoes elastic deformation under the action of the pressure difference to open the second connection port 22a, thereby allowing outside air to enter the second liquid storage chamber 21a. When the pressure inside the second liquid storage chamber 21a is not less than the pressure of the outside atmosphere, the second vent valve 22 returns to its elastic deformation to close the second connection port 22a, thereby isolating the second liquid storage chamber 21a from the outside atmosphere.

[0101] Therefore, through the aforementioned opening and closing mechanism, the second air exchange valve 22 can dynamically balance the pressure of the second liquid storage chamber 21a. When the pressure of the second liquid storage chamber 21a is insufficient, air is promptly added to prevent the atomizing liquid from being unable to flow from the first liquid storage chamber 11a to the second liquid storage chamber 21a and the atomizing core 23 due to negative pressure, thus ensuring smooth liquid flow. When the pressure of the second liquid storage chamber 21a is normal, the second connecting port 22a is sealed to prevent leakage.

[0102] For example, please refer to Figures 3 to 6 The first ventilation valve 12 includes a mounting portion 121 and a deformable portion 122 capable of elastic deformation. The deformable portion 122 is disposed on one side of the mounting portion 121, and the shape of the deformable portion 122 gradually shrinks in the direction away from the mounting portion 121. A portion of the first flow channel 12b is located inside the mounting portion 121, and another portion of the first flow channel 12b is located in the deformable portion 122. The first connecting port 12a is disposed in the deformable portion 122 and is located at one end of the deformable portion 122 away from the mounting portion 121.

[0103] The mounting part 121 is the basic support structure for the deformable part 122, used to fix the deformable part 122. The deformable part 122 is provided with a first communication port 12a, and the deformable part 122 closes the first communication port 12a through elastic deformation. By providing the mounting part 121 and the deformable part 122, the installation stability of the first ventilation valve 12 can be ensured, and the first ventilation valve 12 can have a better anti-leakage and ventilation effect.

[0104] Please see Figure 3 and Figure 4 The structure of the second ventilation valve 22 can be similar to that of the first ventilation valve 12, and will not be described in detail here.
