Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of the present invention should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0031] Traditional atomizers often use resistance heating to atomize the liquid. This heating method requires the resistance heating element to be connected to a power supply circuit and then in direct contact with the liquid. However, resistance heating elements typically have the heating circuit located outside the liquid-containing cavity, and the liquid is transported to the resistance heating element through a liquid guiding channel. This design is prone to liquid leakage and has a complex structure, affecting assembly efficiency.

[0032] This invention provides an atomizer; please refer to [link / reference]. Figures 1-6 ,include: The housing 1 has an air inlet 131 at one end and an air outlet 121 at the other end. Liquid storage component 21 is installed inside the housing 1. The liquid storage component 21 has a porous structure and allows gas to flow while adsorbing and storing the atomized liquid. Electromagnetic heating element 22 is disposed inside liquid storage component 21; The suction nozzle 3 is connected to the housing 1. A suction channel 30 is provided through the suction nozzle 3. The suction channel 30 is connected to the air inlet 131 through the air outlet 121. The liquid storage component 21 is defined on the communication path between the air inlet 131 and the air outlet 121.

[0033] In the atomizer structure of this application, the housing 1 serves as the overall mounting carrier, with an air inlet 131 at one end for airflow to provide the basis for the atomization process. The liquid storage component 21 is fitted and installed within the cavity of the housing 1. The liquid storage component 21 employs a porous adsorption structure design, which on the one hand stably adsorbs and stores the atomized liquid, and on the other hand allows gas to pass through smoothly, achieving integration of liquid storage and gas delivery. An electromagnetic heating element 22 is installed inside the liquid storage component 21 and can directly act on the adsorbed liquid within the liquid storage component 21. The atomizing liquid enables efficient heating and atomization. An air outlet 121 is provided at the other end of the housing 1, and the nozzle 3 is located on the side where the air outlet 121 is located. The nozzle 3 has a suction channel 30 that allows the user to draw in the mist. The suction channel 30 forms a complete communication path with the air inlet 131 through the air outlet 121 of the housing 1. The liquid storage component 21 is precisely defined on the airflow channel between the air inlet 131 and the air outlet 121 to ensure that the airflow can fully carry the atomized mist when it flows through the liquid storage component 21.

[0034] Compared to traditional resistance heating atomizers that require complex liquid guiding channels, the liquid storage component 21 in this application adopts a porous structure, which can directly absorb and store the atomizing liquid. Structurally, this eliminates the risk of leakage caused by the complex sealing channel structure during the delivery of the atomizing liquid, improves the reliability of the atomizer, and avoids atomizing liquid waste and safety hazards. This application integrates the liquid storage and guiding functions into the liquid storage component 21, and the electromagnetic heating element 22 is directly set inside the liquid storage component 21. There is no need for an external heating circuit to connect to the atomizing liquid. The overall number of parts is reduced, the assembly process is simplified, and the assembly efficiency of the atomizer is effectively improved, while the production and manufacturing costs are reduced. The electromagnetic heating element 22 is located inside the liquid storage unit 21, allowing direct heating of the atomizing liquid stored in the unit. This results in more uniform heating and a faster response, avoiding problems such as uneven atomization and scorching caused by the delayed transmission of heat through the beam in traditional resistance heating. Simultaneously, the liquid storage unit 21 allows for gas flow, with the air inlet 131, liquid storage unit 21, air outlet 121, and suction channel 30 forming a complete and smooth airflow channel. During suction, the airflow can fully contact the atomized mist, improving the atomization volume and suction experience. Furthermore, electromagnetic heating eliminates the need for direct contact between the heating circuit and the atomizing liquid, avoiding risks such as circuit breaks and leakage compared to traditional resistance heating, while also reducing the generation of harmful substances during heating, making it safer to use.

[0035] In some embodiments, please refer to Figures 1-6 , Figure 8 and Figure 9A groove 23 is provided at the position of the liquid storage component 21 facing the air outlet 121. The groove 23 communicates with the air outlet 121. The electromagnetic heating element 22 is disposed in the groove 23 and abuts against the side wall of the groove 23. By providing the groove 23 at the position of the liquid storage component 21 facing the air outlet 121, the electromagnetic heating element 22 is embedded in the groove 23 and abuts against the side wall of the groove 23, achieving precise positioning of the heating element and preventing the electromagnetic heating element 22 from shifting due to shaking during use. This ensures a constant heating position and a stable atomization effect. The electromagnetic heating element 22 is tightly fitted to the wall of the groove 23, eliminating the air gap between the electromagnetic heating element 22 and the liquid storage component 21, preventing heat loss. Heat energy is directly conducted to the atomized liquid in the liquid storage component 21 through the contact surface, resulting in a faster heating response speed and immediate mist output upon inhalation without any delay. The groove 23 is connected to the air outlet 121. The mist generated by atomization can quickly enter the suction channel 30 through the air outlet 121, so that there is no suction on the back. This reduces the residence time of the mist in the shell 1, avoids the condensation and backflow of the mist and the residue of odor, and ensures a clear and pure suction taste.

[0036] Understandably, the groove 23 serves a guiding function, allowing the atomized mist in the liquid reservoir 21 to better converge through the groove 23 and enter the air outlet 121, thus improving suction efficiency. Furthermore, the groove 23 can be a rectangular groove, and the electromagnetic heating element 22 can be adapted to be sheet-like, installed in the groove 23 and abutting at least one side wall of the groove 23; for example... Figure 8 As shown, the groove 23 can be vertically positioned in the middle of the liquid storage component 21, and the periphery of the groove 23 is completely closed; Figure 9 As shown, the groove 23 can be vertically positioned in the middle of the liquid storage component 21, and one side of the groove 23 extends to the edge of the liquid storage component 21 in the circumferential direction, forming a notch on the circumference of the liquid storage component 21, which facilitates faster installation of the electromagnetic heating element 22 during the processing of the liquid storage component 21. Of course, as... Figure 7 As shown, the electromagnetic heating element 22 can also be directly installed inside the liquid storage component 21 during the processing, that is, the liquid storage component 21 does not have a groove 23.

[0037] In some embodiments, the liquid storage component 21 is a cotton-like body or a porous ceramic body, the bottom of the groove 23 is located in the liquid storage component 21 and extends towards the air inlet 131 and extends to a position that does not penetrate the liquid storage component 21, and the positions of the air inlet 131, the electromagnetic heating element 22 and the air outlet 121 form a straight line.

[0038] Specifically, when the liquid storage component 21 is a porous ceramic body, the electromagnetic heating element 22 can be implanted inside it during the processing and molding of the porous ceramic body; when the liquid storage component 21 is a cotton body, the electromagnetic heating element 22 can be implanted inside it during the processing and molding of the cotton body, or it can be inserted into the cotton body after the cotton body is molded. The electromagnetic heating element 22 can be strip-shaped, spiral spring-shaped, granular, ring-shaped, or other structural shapes, and there are no restrictions on it. The bottom of the groove 23 extends towards the air inlet 131 but does not penetrate the bottom of the liquid storage component 21. This ensures that the atomizing liquid exists only in a porous adsorbed state, preventing the formation of a liquid leakage channel along the groove 23, thus structurally eliminating leakage. Furthermore, the bottom of the groove 23 provides support for the electromagnetic heating element 22, allowing it to fit tightly against the liquid storage component 21 when embedded within the groove 23, ensuring full contact with the atomizing liquid adsorbed inside the liquid storage component 21. This prevents the electromagnetic heating element 22 from detaching from the atomizing liquid and burning dry. Simultaneously, the liquid storage component 21 has a porous and breathable structure, allowing airflow to pass through normally without affecting air intake atomization. In addition, the air inlet 131, the air outlet 121 of the electromagnetic heating element 22, and the air outlet are arranged in a straight line, allowing the airflow to directly reach the core heating area. The mist can then be quickly discharged in a straight line, with no detours or resistance losses, further improving the smoothness and uniformity of the mist output and ensuring a stable suction feel. Figure 7 The liquid storage component shown is a porous ceramic body or a cotton body, and the electromagnetic heating element 22 is implanted inside the liquid storage component 21 during the molding process. Figure 8 and Figure 9 The body is made of cotton, and the electromagnetic heating element 22 is inserted into the liquid storage component 21 after it is formed.

[0039] Understandably, both the cotton-like body and the porous ceramic body are porous structures adapted to the core function of the liquid storage component 21, possessing excellent atomizing liquid adsorption capacity and gas flow performance, and can stably achieve integrated liquid storage and gas conduction, perfectly matching the built-in installation method of the electromagnetic heating element 22; at the same time, both are non-toxic, high temperature resistant, and chemically stable, ensuring user safety; and both can be adapted to the modular assembly structure of the atomizer, reducing production adaptation costs and improving assembly versatility; the cotton-like body and the porous ceramic body can be flexibly selected as the liquid storage component 21 according to usage requirements, both of which can achieve stable storage of atomizing liquid and smooth gas flow.

[0040] Specifically, the cotton-like body, a porous material composed of natural cotton fibers, possesses an ultra-high atomizing liquid adsorption rate and capacity, capable of quickly adsorbing sufficient atomizing liquid to meet the needs of short-duration, high-frequency atomization. Its soft and highly malleable material can adapt to different shaped shell cavities, resulting in a better fit during assembly and minimizing gaps. Its low cost allows for mass production, making it suitable for mass-market, disposable, or low-cost atomizer applications, offering outstanding value. The porous ceramic body exhibits superior high-temperature resistance, capable of withstanding the long-term high-temperature operation of the electromagnetic heating element 22. It is less prone to aging, deformation, or carbonization, resulting in a lifespan far exceeding that of the cotton-like body. Its strong adsorption stability prevents atomizing liquid from precipitating out after adsorption, avoiding waste and ensuring uniform and stable atomization output. Its high material hardness reduces debris generation, minimizing impurities in the mist and further enhancing the vaping experience, making it suitable for high-end, long-term atomization applications.

[0041] In some embodiments, please refer to Figures 1-6 The housing 1 includes an outer shell 11, a top cover 12, and a base 13. The outer shell 11 has openings at both ends, and the top cover 12 and base 13 are respectively encapsulated at the openings at both ends of the outer shell 11. An air inlet 131 is located on the base 13, and an air outlet 121 is located on the top cover 12. The top cover 12 and base 13 cooperate to define the position of the liquid storage component 21 within the outer shell 11. The outer shell 11 is tubular. The upper end of the base 13 extends into the lower opening of the outer shell 11. The periphery of the base 13 is sleeved with the inner wall of the outer shell 11, and the lower end of the base 13 abuts against the lower end of the outer shell 11 to define the installation position of the base 13 on the outer shell 11. The air inlet 131 is axially penetrating the middle of the base 13. The liquid storage component 21 is located between the top cover 12 and the base 13, and a suction nozzle 3 is located at the upper end of the outer shell 11.

[0042] Understandably, the housing 1 adopts a modular structure consisting of an outer shell 11, a top cover 12, and a base 13. Each component can be processed individually and mass-produced. During assembly, it is only necessary to place the liquid storage component 21 into the outer shell 11, and then use the cooperation between the top cover 12 and the base 13 to limit the axial position of the liquid storage component 21. The assembly process is simple, requiring no complex assembly tools, further improving assembly efficiency and reducing production difficulty. The cooperation between the top cover 12 and the base 13 limits the position of the liquid storage component 21 within the chamber of the housing 1, preventing the liquid storage component 21 from shifting during the use of the atomizer, ensuring the relative stability of the electromagnetic heating element 22 and the liquid storage component 21. At the same time, the air outlet 121 is located on the top cover 12, which can be precisely aligned above the liquid storage component 21, ensuring the consistency of heating and atomization effect and the smoothness of airflow. The air inlet 131 is located on the base 13, and the air outlet 121 is located on the top cover 12, forming a symmetrical and smooth airflow channel with the suction nozzle 3 at the top of the outer shell 11. The cooperation between the top cover 12 and the base 13 can further regulate the airflow direction, ensuring that after the airflow enters from the air inlet 131, it can pass evenly through the liquid storage component 21, and be sucked by the user after passing through the air outlet 121 and the suction channel 30 on the top cover 12, thus improving the suction experience.

[0043] In some embodiments, please refer to Figures 1-3 The outer casing 11 has a receiving tube 114 at one end of the air outlet 121, which is connected to the air outlet 121. The suction nozzle 3 is connected to the opening of the receiving tube 114. The receiving tube 114 at the air outlet 121 end of the outer casing 11 is connected to the air outlet 121. The suction nozzle 3 is directly fitted onto the opening of the receiving tube 114, achieving precise alignment and assembly between the suction nozzle 3 and the outer casing 11. This ensures complete connection between the suction channel 30 and the air outlet 121, preventing air leakage at the connection gap and ensuring stable airflow during suction. The receiving tube 114 also acts as a buffer and guide for the mist, smoothly guiding the high-speed mist discharged from the air outlet 121 into the suction channel 30 of the suction nozzle 3. This prevents sudden changes in mist flow rate that could cause choking, and also prevents excessively slow flow rate that could cause mist lag, resulting in gentler mist output and more comfortable suction.

[0044] For example, the receiving tube 114 can be formed directly from the outer shell 11 extending in the direction of the user's suction of mist, that is, the receiving tube 114 and the outer shell 11 are integrally formed. The advantage of this is that it reduces the installation of parts and improves the efficiency of parts processing and assembly. Figures 1-3 The receiving tube 114 shown is formed by extending from the outer shell. Of course, in other embodiments, the receiving tube 114 and the outer shell 11 are also configured as separate structures, that is, the two are structurally independent and are connected by a socket joint through an inner and outer sleeve. This is prior art and will not be described in detail here.

[0045] In some embodiments, please refer to Figures 1-3A filter element 4 with a porous structure is installed inside the receiving tube 114. Taking the integrated structure of the receiving tube 114 and the outer shell 11 as an example, the position and function of the filter element 4 are explained. The receiving tube 114 is formed by extending the outer shell 11 towards the air outlet 121. The suction nozzle 3 is located at the end of the receiving tube 114. The filter element 4 is located between the suction nozzle 3 and the upper cover 12. After the electromagnetic heating element 22 heats the atomized liquid below, the mist enters the filter element 4 through the air outlet 121 and is then drawn into the suction channel 30 of the suction nozzle 3 by the user. The filter element 4 can effectively intercept impurities such as debris from the liquid storage component 21 and small amounts of incompletely atomized liquid that may be present in the mist. It can balance the filtration effect and airflow, and can complete the filtration before the mist enters the suction channel 30, making the mist entering the suction channel 30 purer, avoiding impurities from affecting the taste, and improving the user experience. Figures 1-3 The middle receiving tube 114 is formed by extending from the outer shell, and the filter element is installed in the part inside the receiving tube 114.

[0046] Understandably, the filter element 4 has a porous structure, and its core function is to intercept tiny particles generated during atomization, filter impurities in the atomized liquid, guide airflow, and balance suction resistance and taste. When the electromagnetic heating element 22 is working, the mist enters the porous structure of the filter element 4 directly from the air outlet 121, completes filtration, and reaches the mouthpiece 3. Of course, the filter element 4 can be made of materials such as polypropylene needle-punched cotton or polyester fiber cotton. The specific material selection for the filter element 4 can be chosen according to actual needs to meet the user's requirements.

[0047] In some embodiments, a filter element 4 is disposed inside the receiving tube 114, and an air outlet channel 41 is disposed on the filter element 4. The air outlet channel 41 is formed by opening downward from the upper end face of the filter element 4, and the air outlet channel 41 does not penetrate the lower end face of the filter element 4. The air outlet channel 41 is essentially a hollow cylinder disposed on the filter element 4. The position of the air outlet channel 41 corresponds to the position of the suction channel 30, that is, the two are on the same axis. The arrangement of the air outlet channel 41 provides a concentrated flow path for the airflow, avoids the disorderly diffusion of the airflow inside the filter element 4, effectively reduces the suction resistance caused by the pore resistance of the porous structure, reduces the airflow dispersion loss, and makes the user suction smoother without the phenomenon of "air blockage". At the same time, the concentrated airflow can fully carry the atomized mist, reduce the loss of atomization, ensure the amount of mist during suction, and greatly improve the user experience. The porous structure works in conjunction with the air outlet channel 41. The porous structure is responsible for filtration, while the air outlet channel 41 is specifically designed to guide the mist. This ensures that the mist can smoothly enter the suction channel 30 and also allows the mist to fully contact the liquid storage component 21, thus completing the interception of impurities.

[0048] Of course, since the filter element 4 itself has a porous structure, the air outlet channel 41 on the filter element 4 is not necessary. In addition, in order to simulate the style of a cigarette, the mouthpiece 3 can be omitted, and the filter element 4 without the air outlet channel 41 can be used as the mouthpiece 3. The filter element 4 can adsorb large particles of atomized liquid, condensate and other impurities during the use of the atomizer, thereby improving the user's vaping experience.

[0049] In some embodiments, please refer to Figures 4-6 The nozzle 3 includes a nozzle shell 31 and an inner tube 32. The nozzle shell 31 is located on the outer periphery of the inner tube 32. The nozzle shell 31, the inner tube 32, and the outer shell 11 define and form a liquid storage cavity. The outer shell 11 is provided with a liquid inlet 113, and the upper cover 12 is provided with a flow channel to guide the atomized liquid in the liquid storage cavity to flow through the liquid inlet 113 to the liquid storage component 21 and be absorbed by the liquid storage component 21. By utilizing the space enclosed by the nozzle shell 31, the inner tube 32, and the outer periphery of the outer shell 11 to form a liquid storage cavity, the problem of the limited storage capacity of the liquid storage component 21 is improved, the frequency of atomized liquid filling is reduced, and the service life of the atomizer is extended.

[0050] For example, the inner tube 32 is a hollow tubular structure. A suction channel 30 is provided in the middle of the inner tube 32 in the axial direction, which penetrates the inner tube 32. The nozzle shell 31 is a cover structure in which the side wall of the inner tube 32 extends in the circumferential direction and partially wraps around the outer periphery of the inner tube 32. The lower end of the inner tube 32 is tightly fitted into the space defined by the end of the upper cover 12. The upper cover 12 is installed in the upper opening of the outer shell 11 and the end of the upper cover 12 is supported by the end of the outer shell 11. The nozzle shell 31 is supported on the outer shell 11. The outer side of the inner tube 32, the inner side of the nozzle shell 31 and the upper end of the shell 1 define a liquid storage chamber, which can store a certain amount of atomized liquid as a spare liquid storage space. When the atomized liquid adsorbed by the liquid storage component 21 is gradually consumed, the atomized liquid in the liquid storage chamber can be continuously replenished to the liquid storage component 21 through the liquid inlet 113 and the flow channel of the upper cover 12, without the need to frequently disassemble the atomizer to add atomized liquid, thus improving the atomizer's endurance. One end of the flow channel of the upper cover 12 is positioned corresponding to the position of the liquid inlet 113, ensuring that the atomized liquid in the liquid storage chamber can enter the flow channel through the liquid inlet 113. The other end of the flow channel of the upper cover 12 is positioned towards the side where the liquid storage component 21 is located, so that the atomized liquid can be absorbed and stored by the liquid storage component 21 after passing through the flow channel.

[0051] In some embodiments, please refer again Figures 4-6 The outer shell 11 is provided with an annular protrusion 111 around the outer periphery of the air outlet 121. An extension tube 112 extends from the end face of the annular protrusion 111 toward the mouthpiece 3. The upper cover 12 extends into the cavity of the outer shell 11 along the extension tube 112 and is supported on the end of the extension tube 112. The mouthpiece shell 31 is supported on the annular protrusion 111.

[0052] For example, the upper end of the top cover 12 is provided with an annular step 122, and the lower end of the top cover 12 extends into the cavity of the outer shell 11 along the extension tube 112. The annular step 122 is supported on the end of the extension tube 112 to achieve stable installation of the top cover 12. The lower end of the inner tube 32 is provided with a first step portion 321 on its outer periphery, and the lower end portion of the inner tube 32 is fitted into the space of the top cover 12 (essentially a blind groove provided on the upper end of the top cover 12 for the lower end of the inner tube 32 to be inserted and fitted). The first step portion 321 contacts the end face of the annular boss 111. The end of the opening end of the suction nozzle shell 31 is provided with a second step portion 311, and the second step portion 311 is supported on the annular boss 111.

[0053] Understandably, the annular protrusion 111 on the outer periphery of the outer shell 11 provides a stable support reference for the nozzle shell 31, ensuring that the nozzle 3 can be accurately assembled with the outer shell 11, avoiding the displacement of the nozzle 3 that would cause misalignment between the suction channel 30 and the air outlet 121, and ensuring smooth airflow. The extension tube 112 formed by extending from the end face of the annular protrusion 111 provides an installation carrier for the upper cover 12 and allows the upper cover 12 to extend into the cavity of the outer shell 11 along the extension tube 112, achieving a deep nesting fit between the upper cover 12 and the outer shell 11. Combined with the structure of the upper cover 12 being supported at the end of the extension tube 112, the positioning accuracy of the upper cover 12 is further improved. This dual positioning structure ensures that the upper cover 12 and the base 13 are precisely matched, firmly limiting the position of the liquid storage component 21 on the outer shell 11, preventing the liquid storage component 21 from shifting due to vibration, suction, or other actions, and ensuring the stability of liquid supply and atomization from a greater distance. Furthermore, the upper cover 12 extends into the cavity of the outer shell 11 along the extension tube 112, forming a nested sealing surface between the upper cover 12 and the extension tube 112. The lower end of the inner tube 32 is fitted into the space of the upper cover 12, squeezing the annular step 122, effectively blocking the leakage of atomized liquid from the mating gap between the extension tube 112 and the upper cover 12, and the mating gap between the inner tube 32 and the upper cover 12. On this basis, the nozzle shell 31 is supported on the annular boss 111, forming a tight seal between the nozzle 3 and the outer shell 11, preventing air from entering the interior of the outer shell 11 from the gap between the nozzle 3 and the outer shell 11, and preventing leakage of atomized mist. The synergistic effect of the multiple sealing structures not only eliminates the waste of resources and pollution caused by leakage of atomized liquid, but also avoids airflow turbulence affecting the suction experience, greatly improving the reliability of product use. Of course, in order to ensure the sealing effect between the nozzle shell 31 and the annular boss 111, glue or other methods can be applied to further seal the contact area between the two to improve the sealing effect, which is a conventional technical means.

[0054] In some embodiments, the liquid inlet 113 is disposed on the wall of the extension tube 112, and the flow channel is disposed on the outer periphery of the upper cover 12. The flow channel includes a circumferential flow channel 123 disposed on the upper cover 12 circumferentially and a guide channel 124 disposed on the upper cover 12 axially. The positions of the liquid inlet 113 and the circumferential flow channel 123 are adapted to each other. One end of the guide channel 124 is connected to the circumferential flow channel 123, and the other end of the guide channel 124 is connected to the liquid storage device 21. The circumferential flow channel 123 and the axial guide channel 124 are disposed on the outer periphery of the upper cover 12. The liquid inlet 113 is aligned and adapted to the circumferential flow channel 123. The atomized liquid is first axially and uniformly dispersed through the circumferential flow channel 123, and then axially transported to the entire area of ​​the liquid storage device 21 through the guide channel 124, so as to achieve uniform liquid absorption of the liquid storage device 21, avoid local dry burning due to lack of liquid, and ensure consistent atomization effect.

[0055] For example, the liquid inlet 113 is disposed on the wall of the extension tube 112 and is adapted to the position of the circulation channel 123 on the outer periphery of the upper cover 12 (that is, when the upper cover 12 is installed on the extension tube 112, the vertical height position of the liquid inlet 113 is the same as the vertical height position of the circulation channel 123). The liquid inlet 113 connects the liquid storage chamber and the flow channel, so that the atomized liquid in the liquid storage chamber can flow into the liquid storage component 21 along the flow channel. The circulation channel 123 is disposed circumferentially on the outer wall of the upper cover 12, and the guide channel 124 is disposed axially on the outer wall of the upper cover 12. The upper end of the guide channel 124 is connected to the circulation channel 123, and the lower end of the guide channel 124 faces the liquid storage component 21. The coordinated design of the circulation channel 123 and the flow channel 124 can buffer the flow rate of the atomizing liquid, avoiding situations where the liquid supply is too fast or interrupted due to tilting or vibration of the atomizer. At the same time, the circulation channel 123 can temporarily store a small amount of atomizing liquid. When the atomizing liquid adsorbed by the liquid storage component 21 is consumed, the flow channel 124 can continuously and stably supply liquid, ensuring the continuity of the atomization process, which is suitable for daily carrying and mobile use scenarios. In this embodiment, the extension tube 112 has two oppositely arranged liquid inlets 113 on its tube wall, and the outer periphery of the top cover 12 has two oppositely arranged flow channels 124 arranged axially. The upper ends of the two flow channels 124 are connected to the circulation channel 123, and the lower ends of the two flow channels 124 are facing the liquid storage device 21. The two liquid inlets 113 can quickly and continuously supply atomizing liquid, and the circulation channel 123 can axially and evenly distribute the atomizing liquid flowing into the liquid inlets 113 to the two flow channels, ensuring that the liquid storage device 21 uniformly absorbs the atomizing liquid, avoiding local insufficient liquid supply that causes dry burning and uneven atomization, and improving atomization consistency.

[0056] Understandably, if the top cover 12 does not have a circulation channel 123, it is essential to ensure that the positions of the guide channel 124 and the liquid inlet 113 are precisely aligned; otherwise, the atomizing liquid will not flow smoothly into the liquid storage unit 21, leading to a liquid supply failure. In this application, the circulation channel 123 can be adapted to have the liquid inlet 113 located anywhere on the entire circumference of the extension tube 112. As long as the height of the circulation channel 123 is the same as the height of the liquid inlet 113, the liquid inlet 113 and the guide channel can be connected, reducing the precision requirements for parts processing and assembly difficulty, and decreasing the product defect rate due to assembly errors. Of course, other numbers of liquid inlets 113 and guide channels 124 can also be provided; this application does not impose any restrictions on this.

[0057] The present invention also provides an electromagnetic heating atomizing device, including a main unit and an atomizer as described in any of the preceding embodiments. The main unit is used to provide electromagnetic induction energy to the atomizer. The main unit is provided with a mounting cavity for accommodating the atomizer. The bottom of the mounting cavity is provided with an airflow channel connecting to the outside. Outside air enters the atomizer through the airflow channel and the air inlet 131.

[0058] Specifically, the main unit has a tubular structure, and the atomizer is installed inside the mounting cavity of the main unit. A coil is wound on the inner wall of the mounting cavity. When energized, electromagnetic induction energy is applied to the electromagnetic heating element 22 of the atomizer inside the mounting cavity, thereby causing the electromagnetic heating element 22 to heat up and atomize the atomized liquid in the liquid storage container 21. The generated mist enters the suction channel 30 through the air outlet 121 for the user to inhale. The airflow channel is adapted to the position of the air inlet 131 to ensure smooth airflow into the atomizer. Of course, in order to realize the basic functions of the electromagnetic heating atomizing device, the mounting cavity is also equipped with basic components such as a power supply, control module, and circuit board. These will not be further described here. The connection method, installation structure, and control principle of the basic components are existing technologies and are not within the scope of protection of this application.

[0059] In summary, this invention discloses an atomizer and an electromagnetically heated atomizing device, relating to the field of atomization technology. The atomizer includes: a housing with an air inlet at one end and an air outlet at the other end; a liquid storage component housed within the housing, the liquid storage component having a porous structure that allows gas flow while absorbing and storing the atomized liquid; an electromagnetic heating element disposed within the liquid storage component; and a suction nozzle connected to the housing, through which a suction channel is provided, communicating with the air inlet via the air outlet. The liquid storage component is defined on the communication path between the air inlet and the air outlet. The atomizer of this application utilizes a porous structure in its liquid storage component, allowing direct absorption and storage of the atomized liquid, structurally eliminating the risk of leakage during liquid transport due to complex sealing channel structures. By integrating liquid storage and guiding functions into the liquid storage component and directly placing the electromagnetic heating element within it, the overall number of components is reduced, and the assembly process is simplified.
