[0002] An electronic atomization structure is a device that atomizes atomized liquid (such as tobacco oil) into gas or tiny particles. It is widely used in medical equipment, electronic cigarettes and other devices.

[0003] Currently, electronic atomizers typically consist of a liquid reservoir, a liquid guide, a liquid storage structure, and an atomizer assembly. Liquid in the reservoir flows through the liquid guide to the liquid reservoir, a process that requires precise control to prevent leakage and ensure rapid and even delivery of liquid during heating.

[0004] However, to achieve a sealed liquid storage structure and prevent leakage, related technologies often require additional air intake holes in other components of the electronic atomizer structure to provide the necessary air circulation during the heating process, allowing the e-liquid to be fully atomized. This approach complicates the electronic atomizer structure, not only increasing the number of components and manufacturing costs, but also potentially leading to sealing issues due to assembly gaps between components, further increasing the risk of leakage.

Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that meet both A and B.

[0046] This utility model provides an electronic atomization structure. An electronic atomization structure is a device that uses electrical energy to heat a specific substance (such as tobacco oil) and atomize it. This type of device is widely used in various fields, including but not limited to electronic cigarettes, medical atomizers, and fragrance diffusers. In the field of electronic cigarettes, the electronic atomization structure 100, as a special form of electrically heated atomizer, achieves efficient atomization and safe use of electronic cigarette oil.

[0047] In the embodiment of this utility model, please refer to Figures 1 to 3The electronic atomization structure 100 includes a liquid storage component 10 and an atomization component 20. The liquid storage component 10 is the main storage space, responsible for providing a stable supply of liquid to the atomization component 20 during the atomization process. The atomization component 20 is responsible for atomizing the atomized liquid (such as e-liquid) into gas or small particles for the user.

[0048] Reference Figure 5 、 Figures 11 to 15 The liquid storage component 10 is provided with a receiving groove 111, a liquid storage cavity 112 arranged around the receiving groove 111, an exhaust channel 113 connecting the outside of the liquid storage component 10 and the receiving groove 111, and a liquid outlet 121 connecting the liquid storage cavity 112.

[0049] The accommodating tank 111 is a space specifically designed for the porous matrix 23 or other key components in the atomizer assembly 20. It serves to secure and support these components. The liquid storage chamber 112 is the primary area for storing e-cigarette liquid. It is typically designed to hold a certain amount of atomized liquid and is connected to the atomizer assembly 20 via specific structures (such as the liquid outlet 121 and the liquid guide structure 21).

[0050] The exhaust channel 113 connects the exterior of the liquid reservoir 10 to the accommodating tank 111 (or atomization area). Its primary function is to allow outside air to enter the liquid reservoir 10, mixing with the aerosol after atomization, thereby adjusting the concentration, taste, and temperature of the smoke. The liquid outlet 121 connects the liquid reservoir 112 to the atomization assembly 20, responsible for transporting the e-cigarette liquid in the liquid reservoir 112 to the atomization area for atomization.

[0051] Reference Figure 7 The atomizing assembly 20 includes a liquid guiding structure 21, a heating element 22 and a porous matrix 23. The liquid guiding structure 21 includes a liquid guiding seat 211 connected to the liquid outlet 121. A liquid storage tank 212 is provided on the liquid guiding seat 211. An air inlet 2122 is provided at the bottom of the liquid storage tank 212.

[0052] The main function of the liquid guiding structure 21 is to guide the electronic cigarette oil flowing out of the liquid storage component 10 through the liquid outlet 121 to the atomization area, and to perform preliminary storage and distribution. Among them, the liquid guiding seat 211, as the core component of the liquid guiding structure 21, is closely connected with the liquid outlet 121 to ensure that the atomized liquid can flow smoothly into the liquid storage tank 212. The liquid storage tank 212 is a groove opened on the liquid guiding seat 211 for temporarily storing electronic cigarette oil. It can store a certain amount of oil so as to provide a continuous supply of oil when the heating element 22 is heated. The air inlet 2122 is a small hole opened at the bottom of the liquid storage tank 212. Its function is to allow external air to enter the liquid storage tank 212 and work together with the heat generated by the heating element 22 to promote the rapid atomization of the electronic cigarette oil.

[0053] The heating element 22 is a key component in the atomization assembly 20. When powered, it generates heat, heating the atomized liquid in the porous matrix 23 to above its boiling point, causing it to rapidly evaporate and atomize into tiny particles. The heating element 22 includes, but is not limited to, a resistance wire heating element 22, a silicone heating sheet, a PTC heating element, a thin film heating element, and a ceramic heating element. The specific shape of the heating element 22 is not limited herein.

[0054] The porous matrix 23 usually has a porous structure, which can increase the contact area between the electronic cigarette oil and the heating element 22 and improve the atomization efficiency. The porous matrix 23 also has a certain adsorption capacity and can store part of the atomized liquid to ensure that the oil can be continuously and stably provided when the heating element 22 is heated. In addition, the porous structure of the porous matrix 23 also helps to promote the mixing of the atomized aerosol and the external air, making the smoke more uniform and delicate. The porous matrix 23 includes but is not limited to a porous ceramic matrix, a porous metal matrix, a porous polymer matrix (polyurethane or polyvinyl alcohol (PVA)), etc.), and a porous fiber matrix.

[0055] The porous matrix 23 is placed in the accommodating groove 111, and is provided with an air flow channel 231 connecting the air inlet hole 2122 and the exhaust channel 113; a part of the heating element 22 is attached to the porous matrix 23, and the other part is placed in the liquid storage tank 212. The heating element 22 is arranged around the outer periphery of the air inlet hole 2122 and is surrounded by the peripheral wall of the liquid storage tank 212 to form a liquid storage space 2121 for supplying liquid to the porous matrix 23.

[0056] The porous matrix 23 is placed in the receiving groove 111 and fits with the heating element 22. Its porous structure increases the contact area with the atomized liquid and improves the atomization efficiency. At the same time, it can also store a certain amount of atomized liquid to ensure continuous liquid supply during the atomization process. The air flow channel 231 is responsible for connecting the air inlet 2122 and the exhaust channel 113. This means that external air can enter the porous matrix 23 through the air inlet 2122, mix with the atomized aerosol, and be discharged through the exhaust channel 113. This design helps to adjust the concentration and taste of the smoke while ensuring the smooth discharge of the smoke.

[0057] Part of the heating element 22 is attached to the porous matrix 23, and the other part is placed in the liquid storage tank 212. This layout ensures that the heating element 22 can heat the porous matrix 23 and the atomized liquid in the liquid storage tank 212 at the same time, thereby improving the atomization efficiency. In addition, the heating element 22 is also arranged around the periphery of the air inlet 2122. On the one hand, this helps to further promote the atomization of the electronic cigarette oil and its mixing with the external air; on the other hand, it can isolate the air inlet 2122 and the liquid storage space 2121, preventing the atomized liquid from flowing into the air inlet 2122, resulting in a reduction in the effectively usable atomized liquid and a poor atomization effect.

[0058] The air inlet 2122 and the liquid storage space 2121 are both provided in the liquid storage tank 212, realizing an integrated structural design, reducing the number and complexity of parts. This design makes the entire electronic atomization structure more compact and reduces errors and inconveniences that may occur during assembly.

[0059] The liquid storage space 2121 is formed by the heating element 22 and the surrounding wall of the liquid storage tank 212. This space not only stores the atomized liquid, providing a stable supply of oil to the porous matrix 23, but also maintains the atomized liquid in the liquid storage space 2121 at a certain temperature through the heating effect of the heating element 22, thereby improving the atomization efficiency.

[0060] The present invention provides a liquid storage tank 212 on the liquid guide structure 21, and an air inlet hole 2122 is provided at the bottom of the liquid storage tank 212; and the heating element 22 is arranged around the periphery of the air inlet hole 2122, and is enclosed with the peripheral wall of the liquid storage tank 212 on the liquid guide structure 21 to form a liquid storage space 2121. In this way, the electronic atomization structure 100 can achieve air circulation inside the electronic atomization structure 100 only through the liquid guide structure 21, and can also achieve the closedness of the liquid storage space 2121 to prevent liquid leakage. This reduces the number of parts in the electronic atomization structure 100, reduces the difficulty of assembly and manufacturing costs. At the same time, the heating element 22 is in direct contact with the atomized liquid (smoke oil) in the liquid storage space 2121, reducing heat loss and improving atomization efficiency.

[0061] Furthermore, Figures 11 to 15 The liquid guiding structure 21 also includes a slow flow member 213 protruding from the liquid guiding seat 211, and the slow flow member 213 is arranged on the same side as the liquid storage tank 212; the slow flow member 213 is inserted into the liquid outlet 121 to guide the liquid in the liquid storage cavity 112 to the liquid storage tank 212.

[0062] In this embodiment, the flow retarder 213 is a component that reduces the velocity of the oil entering the liquid reservoir 212. It guides the atomized liquid into the liquid reservoir 212 at a predetermined velocity and direction, preventing the atomized liquid from directly impacting or splashing out of the liquid reservoir 212, thereby improving the efficiency of oil utilization. The flow retarder 213 can be located at the bottom of the liquid reservoir 212 or around the liquid reservoir 212, without limitation.

[0063] The slow-flow member 213 protrudes from the liquid guide seat 211 and is arranged on the same side as the liquid storage tank 212. This allows the slow-flow member 213 to be directly inserted into the liquid outlet 121 of the liquid storage assembly 10, thereby achieving accurate diversion of the electronic cigarette liquid flowing out of the liquid storage chamber 112.

[0064] By precisely guiding and slowing down the flow, the slowing down member 213 can ensure that the atomized liquid enters the liquid storage tank 212 in an optimal state and is atomized. This helps to improve the atomization efficiency, making the smoke richer and more flavorful.

[0065] Further, refer to Figure 8 、 Figure 9 A first liquid guiding groove 2131 is provided on the slow flow member 213, and the first liquid guiding groove 2131 extends from one end of the slow flow member 213 close to the liquid outlet 121 toward the liquid guiding seat, and the first liquid guiding groove 2131 is connected to the liquid storage tank 212; the bottom wall of the first liquid guiding groove 2131 is set at an angle to the liquid outlet direction of the liquid outlet 121.

[0066] The opening of the first liquid guide groove 2131 provides a clear flow path for the electronic cigarette oil, ensuring that the oil can enter the liquid storage tank 212 smoothly and stably. The first liquid guide groove 2131 can be set on any side surface of the slow-flow component 213, and the notch of the first liquid guide groove 2131 can face any direction as long as it can absorb and store the leaked liquid. The cross-section of the first liquid guide groove 2131 in the direction of gravity can be U-shaped, or V-shaped, semi-circular, or semi-elliptical. The shape of its cross-section is not limited here, as long as it can facilitate drainage and collection. The number of first liquid guide grooves 2131 can be one or more, and is not limited here.

[0067] The bottom wall of the first liquid-conducting groove 2131 is arranged at an angle to the liquid outlet direction of the liquid outlet 121. Thus, the bottom wall of the first liquid-conducting groove 2131 is arranged in a sloped shape, which lengthens the path of the atomized liquid from the liquid outlet 121 to the oil storage space, thereby slowing down the flow rate of the atomized liquid and preventing the atomized liquid from directly impacting or splashing out of the liquid storage tank 212.

[0068] Further, refer to Figure 8 、 Figure 9 The slow-flow member 213 and the liquid storage tank 212 are spaced apart on the side of the liquid guide seat 211 facing the liquid storage component 10; a plurality of second liquid guide grooves 2132 are provided on the side of the liquid guide seat 211 facing the liquid storage component 10; a plurality of first liquid guide grooves 2131 are provided on the slow-flow member 213, and each second liquid guide groove 2132 corresponds to connecting a first liquid guide groove 2131 and the liquid storage tank 212.

[0069] In this embodiment, the flow slowing member 213 is spaced apart from the liquid storage tank 212 and connected to the second liquid guiding groove 2132. Thus, the second liquid guiding groove 2132 increases the path of the atomized liquid from the liquid outlet 121 to the oil storage space, thereby slowing down the flow rate of the atomized liquid.

[0070] Each second liquid guide groove 2132 and the corresponding first liquid guide groove 2131 form an independent diversion channel, ensuring that the electronic cigarette liquid can flow into the liquid storage tank 212 according to the predetermined path and speed. This precise diversion effect helps improve the atomization efficiency and make the smoke more uniform and delicate.

[0071] By providing multiple second liquid guiding grooves 2132 and corresponding first liquid guiding grooves 2131, a diversion is achieved from the liquid storage assembly 10 to the liquid storage tank 212. This diversion effect helps to slow down the flow rate of the atomized liquid, reduce congestion and waste of the atomized liquid during the flow process, and improve the utilization efficiency of the oil.

[0072] In one embodiment, referring to Figures 11 to 15 The heating element 22 is cylindrical and is embedded in the porous matrix 23; a first assembly groove 2123 corresponding to the air flow channel 231 is opened on the bottom wall of the liquid storage tank 212, and an air inlet 2122 is opened on the bottom wall of the first assembly groove 2123; at least a portion of the heating element 22 is placed in the first assembly groove 2123.

[0073] In this embodiment, the heating element 22 is embedded in the porous matrix 23, ensuring close contact between the heating element 22 and the porous matrix 23. This allows heat to be more effectively transferred to the interior of the porous matrix 23, promoting the atomization of the electronic cigarette liquid. The heating element 22 is designed in a cylindrical shape, so that the space formed within the cylindrical wall of the heating element 22 is connected to the airflow channel 231, ensuring that the atomized gas can flow smoothly out of the airflow channel 231.

[0074] In some embodiments, the inner and outer walls of the heating element 22 are provided with a porous matrix 23 , which can increase the contact area with the porous matrix 23 and thus improve the atomization efficiency.

[0075] The air inlet 2122 serves as the entrance for external air to enter the airflow channel 231, ensuring sufficient air participation during the atomization process, which helps to form a fine, uniform vapor. Because the heating element 22 is partially placed in the first assembly groove 2123, its heat can also be dissipated to a certain extent through the wall surface of the liquid reservoir 212, reducing the operating temperature of the heating element 22 and extending its service life.

[0076] The first assembly groove 2123 provides space for the installation of the heating element 22 and ensures isolation between the airflow channel 231 and the liquid reservoir 212, preventing oil from entering the airflow channel 231 and causing blockage or affecting the atomization effect. At the same time, the wall of the first assembly groove 2123 provides a certain degree of support and protection for the heating element 22, preventing it from shaking or being damaged during operation.

[0077] In one embodiment, please refer to Figure 9 A second assembly groove 2124 is provided on the side of the liquid guide seat 211 facing away from the liquid storage component 10; the atomization component 20 also includes a liquid absorption component 25 placed in the second assembly groove 2124; the liquid guide structure 21 also includes a sealing cover 214, which covers the notch of the second assembly groove 2124.

[0078] After the atomized liquid is atomized, it forms gas or small particles. When these gas or small particles come into contact with a cooler surface (such as a cigarette holder or the inside of the device), the temperature drops, causing the vapor to condense and form liquid atomized liquid. In this embodiment, the liquid absorbing member 25 placed in the second assembly groove 2124 can absorb the condensed atomized liquid, preventing the atomized liquid from accumulating inside the electronic atomization structure 100 and clogging the airflow channel 231.

[0079] The sealing cover 214 covers the notch of the second assembly groove 2124, ensuring the sealing during the flow process and preventing the leakage of the atomized liquid.

[0080] In some embodiments, the second assembly groove 2124 is arranged around the first assembly groove 2123, and a wiring bracket can be provided on the side of the liquid guide seat 211 facing away from the liquid storage assembly 10 at a position corresponding to the first assembly groove 2123 to facilitate wiring connection to the heating element 22. In this way, the electronic atomization structure 100 can be made compact.

[0081] Further, refer to Figure 6 、 Figure 7 as well as Figures 11 to 15 The atomizer assembly 20 further includes a mounting bracket 24 that is detachably connected to the liquid storage assembly 10 and / or the cover 214; the liquid guide structure 21, the heating element 22, and the porous substrate 23 are disposed within the mounting bracket 24. In this embodiment, the mounting bracket 24 serves as a support and fixing structure for the atomizer assembly 20, allowing the atomizer assembly 20 to be quickly connected and disconnected from the liquid storage assembly 10 or the cover 214. This facilitates cleaning and maintenance by the user, such as replacing the atomizer assembly 20 or the liquid absorbing element 25, thereby extending the product's service life.

[0082] Furthermore, the mounting frame 24 includes a first bracket 241 for accommodating the porous matrix 23 and a second bracket 242 for accommodating the liquid-conducting structure 21; a vent hole 2412 connecting the exhaust channel 113 and the air flow channel 231 is provided on the top of the first bracket 241; and an avoidance hole 2421 is provided on the second bracket 242 so that the liquid-conducting structure 21 can guide the liquid in the liquid storage chamber 112 to the porous matrix 23.

[0083] In this embodiment, the first bracket 241 is a supporting and fixing structure for the porous matrix 23, and the second bracket 242 is a supporting and fixing structure for the liquid guide structure 21. The vent 2412 ensures a smooth connection between the exhaust channel 113 and the air flow channel 231, thereby improving the atomization effect. This embodiment realizes a modular design of the atomization assembly 20 by subdividing the mounting frame 24 into the first bracket 241 and the second bracket 242. This not only improves the maintainability of the product, but also facilitates replacement and cleaning by the user.

[0084] In some embodiments, the second bracket 242 surrounds the first bracket 241, with the cross-sectional area of ​​the first bracket 241 being smaller than that of the second bracket 242. This wraparound arrangement allows the second bracket 242 to more efficiently utilize the space surrounding the first bracket 241. Furthermore, during disassembly, the user can easily grasp the second bracket 242 to separate the mounting frame 24 from the cover 214 / liquid storage device.

[0085] In some embodiments, the top of the first bracket 241 is provided with an exhaust hole 2411, which is arranged away from the vent hole 2412. The exhaust hole 2411 is used to prevent a negative pressure environment from forming in the first bracket 241, which may result in the porous matrix 23 being unable to fully absorb the atomized liquid.

[0086] In some embodiments, a fourth assembly groove 2422 is defined on the second bracket 242. The fourth assembly groove 2422 is disposed around the avoidance hole 2421. A portion of the sealing ring 124 is positioned within the third assembly groove 1221, and another portion is positioned within the fourth assembly groove 2422. The fourth assembly groove 2422 serves to both indicate the installation position of the sealing ring 124 and to accommodate a portion of the sealing ring 124, thereby preventing misalignment of the sealing ring 124 during assembly of the liquid storage assembly 10 and the atomizer assembly 20.

[0087] In one embodiment, referring to Figures 11 to 15 One end of the porous substrate 23 is placed in the receiving groove 111, and the other end of the porous substrate 23 is arranged adjacent to or within the liquid storage space 2121. In this embodiment, the distance between the porous substrate 23 and the liquid storage space 2121 is short. This helps to reduce the waste of atomized liquid during the transmission process. When the surface of the porous substrate 23 is heated and steam is generated, the atomized liquid in the liquid storage space 2121 can be quickly replenished to the surface of the porous substrate 23, thereby avoiding the situation where the atomization efficiency is reduced or the atomization is interrupted due to insufficient atomized liquid.

[0088] In one embodiment, referring to Figure 10 The porous matrix 23 is further provided with at least two air channels 232 . The air channels 232 are provided at the periphery of the heating element 22 and are connected to the exhaust channel 113 and the liquid storage space 2121 .

[0089] In this embodiment, the air channel 232 is arranged on the periphery of the heating element 22 to enhance the heat dissipation effect and reduce condensation. The heating element 22 generates a large amount of heat during the atomization process, and the air channel 232 helps to reduce the operating temperature of the heating element 22 and improve the stability and service life of the atomization assembly 20. At the same time, during the atomization process, condensation may occur when the steam encounters colder components. The design of the air channel 232 can reduce the possibility of condensation of steam when it flows through the area between the heating element 22 and the liquid storage space 2121, because the air flow can take away some of the heat and reduce the temperature gradient in the area.

[0090] In certain embodiments, the air channel 232 is arranged adjacent to the air channel 231 and communicates with the air channel 231, and the heating element 22 is arranged between the air channel 231 and the air channel 232. In this way, it can be ensured that the gas is reasonably distributed and utilized inside the device, avoiding blockage or waste of gas flow. If the heating element 22 is located between the air channel 232 and the air channel 231, the heating element 22 can directly heat the air in the air channel 231, and at the same time, the hot air can quickly mix with the external cold air from the air channel 232 to form a suitable temperature gradient, which is conducive to the rapid atomization of the liquid and the uniform distribution of the steam. At the same time, the heating element 22 is located between the two channels, making the structure of the entire device more compact and reasonable, which is conducive to reducing the volume and weight of the device.

[0091] At the same time, when the porous matrix 23 absorbs the atomized liquid, the air channel 232 can also perform its exhaust function to avoid the formation of a negative pressure state inside the porous matrix 23, which would prevent the porous matrix 23 from being able to absorb the atomized liquid smoothly. The exhausted gas finally flows to the exhaust channel 113 through the exhaust hole 2411.

[0092] In one embodiment, referring to Figures 11 to 13 The liquid storage assembly 10 includes a shell 11, a liquid blocking plug 12 and a sealing ring 124; the shell 11 and the liquid blocking plug 12 enclose a liquid storage chamber 112; the shell 11 is provided with a accommodating groove 111 and an exhaust channel 113; the liquid blocking plug 12 is provided with a liquid outlet 121; the liquid blocking plug 12 is provided with a third assembly groove 1221 on the side facing the atomizer assembly 20, and the third assembly groove 1221 is arranged around the liquid outlet 121; the sealing ring 124 is placed in the third assembly groove 1221, and the sealing ring 124 is sealed with the atomizer assembly 20.

[0093] In this embodiment, the housing 11 is the main structure of the liquid storage assembly 10 and has a certain strength and rigidity to withstand the pressure of the internal liquid and the impact of the external environment. The liquid blocking plug 12 is tightly matched with the housing 11 to enclose a liquid storage cavity 112.

[0094] When the liquid storage assembly 10 and the atomizer assembly 20 are assembled, the sealing ring 124 is compressed within the third assembly groove 1221 and comes into close contact with the corresponding portion of the atomizer assembly 20. Because the sealing ring 124 is made of an elastic material, it deforms under pressure, thereby filling the tiny gap between the liquid blocking plug 12 and the atomizer assembly 20 and achieving a sealing effect. This sealing structure effectively prevents leakage of the atomized liquid and ensures a smooth atomization process.

[0095] Furthermore, the liquid blocking plug 12 includes a sealing member 123 and a support member 122 that are connected to each other, and the liquid outlet 121 passes through the sealing member 123 and the support member 122; the sealing member 123 is sealed with the inner wall surface of the liquid storage chamber 112 and is detachably connected to the liquid storage chamber 112; a third assembly groove 1221 is provided on the side of the support member 122 facing the atomization assembly 20, and the support member 122 is detachably connected to the shell 11.

[0096] In this embodiment, seal 123 tightly fits the inner wall of liquid storage chamber 112, forming a reliable sealing barrier. Seal 123 and liquid storage chamber 112 are also detachably connected, facilitating quick refilling, cleaning, or replacement when needed. Support member 122 provides support for seal 123 and sealing ring 124.

[0097] In some embodiments, the seal 123 and support member 122 are integrally formed, which reduces the assembly gap between the seal 123 and support member 122, thereby reducing the risk of leakage and improving the sealing performance. Furthermore, the integrally formed design makes the seal 123 and support member 122 a single unit, simplifying the installation process and ensuring the correct installation position and fit of the seal 123 and support member 122.

[0098] The utility model also provides an electronic smoking device, referring to Figures 1 to 4 The electronic smoking device includes a main unit 200 and an electronic atomization structure 100.

The electronic atomization structure 100 is the actual smoke generator and includes key components such as the liquid storage assembly 10 and the atomization assembly 20. Because the main unit 200 and the electronic atomization structure 100 utilize a detachable connection, users can easily separate or combine the two, facilitating portability, oil replacement, and cleaning and maintenance.

[0100] In some embodiments, the atomization assembly 20 further includes a filter 26. The filter 26 is placed in the receiving groove 111 and is located between the exhaust channel 113 and the porous matrix 23. The filter 26 is also provided with a through hole connecting the exhaust channel 113 and the air flow channel 231. The filter 26 absorbs and filters out oil stains and impurities in the tobacco oil and harmful substances in the smoke, such as tobacco tar, heavy metals, etc. Through physical filtration, it can significantly reduce the content of harmful substances inhaled by smokers, thereby reducing damage to the body. The material of the filter 26 includes but is not limited to sponge, knitted cotton, activated carbon and fiber factor, which are not limited here.

[0101] During use, first remove the anti-leakage plug 13 at the liquid outlet 121 on the liquid storage device, then align the first bracket 241 or the porous matrix 23 on the atomizer assembly 20 with the position of the receiving groove 111, and align the liquid guide on the atomizer assembly 20 with the position of the liquid outlet 121 to complete the installation between the liquid storage assembly 10 and the atomizer assembly 20. Next, complete the installation between the host 200 and the electronic atomizer structure 100.
