Description

Technical Field

[0001] This application belongs to the technical field of atomizing devices, specifically relating to an atomizer and an atomizing device. Background Technology

[0002] Currently, most atomizers on the market use a cotton reservoir, where the cotton reservoir is located inside the liquid reservoir (also known as the oil cup). The cotton reservoir is usually made of a single piece of cotton, which is used to store the atomizing medium and has advantages such as easy assembly, high oil retention, and stable oil conduction.

[0003] However, during use, the atomizer is in a negative pressure environment. Under this negative pressure, the atomizer may leak e-liquid from some points, thus affecting the user experience. Utility Model Content

[0004] The purpose of this application is to provide an atomizer and atomizing device that can solve at least some of the above-mentioned problems.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] In a first aspect, embodiments of this application provide an atomizer, comprising: a housing having a mouthpiece and a receiving cavity, the mouthpiece having an inhalation channel communicating with the receiving cavity; a support being disposed within the receiving cavity, the support being connected to the housing, and the support and the housing enclosing a receiving space, the receiving space being close to the mouthpiece; and a liquid suction member being disposed on the side of the support close to the mouthpiece, and the liquid suction member at least partially filling the receiving space; wherein, the receiving cavity includes a liquid storage cavity, the liquid storage cavity being formed by the housing and the support together, the liquid storage cavity being located on the side of the support away from the mouthpiece, and the support having at least one reflux hole along the length direction of the atomizer, the reflux hole communicating with the liquid storage cavity and the receiving space.

[0007] In this embodiment, the shell serves as the main frame of the atomizer, supporting the mouthpiece and the receiving cavity. The airflow channel within the mouthpiece is connected to the receiving cavity, which is further divided into a liquid storage cavity and a receiving space. A support is positioned within the receiving cavity and tightly connected to the shell, together forming the receiving space near the mouthpiece. The liquid storage cavity is formed by the shell and support, located on the side of the support away from the mouthpiece. This spatial arrangement separates the atomizing matrix in the liquid storage cavity from the mouthpiece through the support and the receiving space. When negative pressure is generated, it cannot directly act on the atomizing matrix in the liquid storage cavity, reducing the driving force for the atomizing matrix to flow towards the mouthpiece due to negative pressure. The suction element, as the core component of the entire atomizer, plays a crucial dual role in addressing negative pressure leakage. On one hand, the suction element, positioned on the side of the support near the mouthpiece and filling at least part of the receiving space, acts as a physical barrier layer. When negative pressure forces the atomized matrix in the reservoir to flow towards the nozzle, the suction element, by filling the space, significantly obstructs the flow path of the atomized matrix, acting like a barrier in the flow channel to absorb it. This weakens the direct effect of negative pressure on the atomized matrix and reduces its surging towards the nozzle. Furthermore, the suction element possesses strong adsorption capacity, which is crucial for achieving precise atomized matrix delivery. It can selectively absorb the atomized matrix flowing out of the reservoir using capillary action or the properties of special adsorbent materials.

[0008] The embodiments of this application not only avoid waste and equipment contamination caused by leakage of the atomizing matrix, but also improve the reliability and stability of the product, providing users with a cleaner and safer operating environment, and have the beneficial effect of improving user experience.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0026] The atomizer and atomizing device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0027] See Figures 1 to 3 An embodiment of this application provides an atomizer, comprising: a housing 10 having a mouthpiece 11 and a receiving cavity 12, the mouthpiece 11 having an air intake channel 111 communicating with the receiving cavity 12; a support 20 disposed within the receiving cavity 12, the support 20 being connected to the housing 10, and the support 20 and the housing 10 enclosing a receiving space 121 near the mouthpiece 11; and a liquid suction member 30 disposed on the side of the support 20 near the mouthpiece 11, and the liquid suction member 30 at least partially filling the receiving space 121; wherein, the receiving cavity 12 includes a liquid storage cavity 122, the liquid storage cavity 122 being formed by the housing 10 and the support 20, the liquid storage cavity 122 being located on the side of the support 20 away from the mouthpiece 11, and the support 20 having at least one reflux hole 22 along the length direction of the atomizer, the reflux hole 22 communicating with the liquid storage cavity 122 and the receiving space 121.

[0028] In this embodiment, the housing 10 serves as the main frame of the atomizer, supporting the mouthpiece 11 and the receiving cavity 12. The air intake channel 111 within the mouthpiece 11 is connected to the receiving cavity 12, which is further divided into a liquid storage cavity 122 and a receiving space 121. A support 20 is disposed within the receiving cavity 12 and tightly connected to the housing 10, together forming the receiving space 121 near the mouthpiece 11. The liquid storage cavity 122 is formed by the housing 10 and the support 20, located on the side of the support 20 furthest from the mouthpiece 11. This spatial arrangement separates the atomizing matrix in the liquid storage cavity 122 from the mouthpiece 11 through the support 20 and the receiving space 121. When negative pressure is generated, it cannot directly act on the atomizing matrix in the liquid storage cavity 122, thus reducing the driving force for the atomizing matrix to flow towards the mouthpiece 11 due to negative pressure. The suction element 30, as the core component of the entire atomizer, plays a crucial dual role in addressing negative pressure leakage. On the one hand, the suction element 30 is disposed on the side of the support 20 near the nozzle 11 and fills at least part of the receiving space 121, acting as a physical barrier layer. When negative pressure causes the atomized matrix in the storage chamber 122 to flow towards the nozzle 11, the suction element 30, by filling the receiving space 121, greatly hinders the flow path of the atomized matrix, as if setting up a barrier to absorb the atomized matrix in the flow channel, weakening the direct effect of negative pressure on the atomized matrix and reducing the surge of the atomized matrix towards the nozzle 11. On the other hand, the suction element 30 has a strong adsorption capacity, which is the key to its precise atomized matrix delivery. It can selectively absorb the atomized matrix flowing out of the storage chamber 122 by utilizing capillary action or special adsorption material properties.

[0029] Furthermore, during normal inhalation and the generation of negative pressure, the atomized matrix absorbed by the suction element 30 is orderly drawn into the inhalation channel 111, realizing the atomization inhalation process. However, when an abnormal negative pressure is generated in the external environment, potentially causing a large amount of atomized matrix in the reservoir 122 to flow towards the mouthpiece 11, the suction element 30 can quickly adsorb the excess atomized matrix, locking it firmly within its own structure to prevent overflow from the mouthpiece 11. This "on-demand adsorption, on-demand release" mechanism ensures that the atomizer maintains a stable atomized matrix transport state under various negative pressure environments. In a negative pressure environment, a dynamic balance system is formed among the various components inside the atomizer. When external negative pressure acts on the atomizer, although the atomized matrix in the reservoir 122 tends to flow towards the mouthpiece 11, the adsorption effect of the suction element 30 and the physical barrier formed by the support 20 and the shell 10 jointly restrict the flow of the atomized matrix. Meanwhile, the liquid suction component 30 automatically adjusts the amount of atomized matrix adsorbed and released according to the changes in negative pressure within the inhalation channel 111. When the user inhales normally, the negative pressure within the inhalation channel 111 increases, and the liquid suction component 30 releases an appropriate amount of atomized matrix into the inhalation channel 111 for atomization. When the external environment generates interfering negative pressure, the liquid suction component 30 enhances its adsorption capacity, stores excess atomized matrix, and prevents it from overflowing.

[0030] In practical applications, when the atomizer is under negative pressure, the reflux orifice 22 becomes the key channel for the atomized matrix to flow from the first liquid storage chamber 40 to the suction element 30. The suction force generated by the negative pressure causes the atomized matrix in the first liquid storage chamber 40 to flow into the receiving space 121 through the reflux orifice 22 and be adsorbed by the suction element 30. When the atomizer is not under negative pressure, the reflux orifice 22 plays a reverse transmission role. The atomized matrix in the suction element 30 can flow back to the first liquid storage chamber 40 through the reflux orifice 22. This mechanism effectively avoids the accumulation of atomized matrix at the suction element 30 and prevents the atomized matrix from overflowing from the nozzle 11 due to gravity or vibration, reducing the waste of atomized matrix. The setting of the reflux orifice 22 gives the atomizer's atomized matrix transmission system bidirectional adjustment capability, enabling efficient circulation and precise control of the atomized matrix under both negative and normal conditions, significantly improving the performance and reliability of the product.

[0031] The embodiments of this application not only avoid waste and equipment contamination caused by leakage of the atomizing matrix, but also improve the reliability and stability of the product, providing users with a cleaner and safer operating environment, and have the beneficial effect of improving user experience.

[0032] Optionally, in this embodiment of the application, a plurality of reflux holes 22 are evenly distributed on a plane perpendicular to the length direction of the atomizer.

[0033] In this embodiment, with the central axis of the atomizer as the center, multiple return holes 22 are distributed in a ring, radial, or equiangular pattern on the same cross-section of the support 20, with the distance or central angle between adjacent return holes 22 being approximately equal. The uniform distribution of the multiple return holes 22 allows the atomizing matrix in the liquid storage chamber 122 to flow evenly into the receiving space 121 under negative pressure, and to be evenly adsorbed by various areas of the suction element 30, avoiding overflow that might occur due to excessive local atomizing matrix caused by the concentrated distribution of the return holes 22. If the return holes 22 are concentrated on one side of the support 20, the atomizing matrix will preferentially flow into the receiving space 121 from that side under negative pressure, causing unilateral overload and oil leakage in the suction element 30; a uniform distribution, on the other hand, can balance the distribution of the atomizing matrix through the overall adsorption capacity of the suction element 30.

[0034] Furthermore, the uniform distribution perpendicular to the length direction ensures a more balanced transmission of negative pressure across the cross-section of the support 20, preventing excessive local negative pressure from causing the atomizing matrix to breach the adsorption range of the liquid suction component 30. When fluctuating negative pressure occurs in the external environment, the uniformly distributed reflux holes 22 can disperse the driving force of the negative pressure on the atomizing matrix, and in conjunction with the overall adsorption effect of the liquid suction component 30, reduce the risk of oil leakage caused by local pressure concentration.

[0035] The liquid suction component 30 is filled into the receiving space 121. The evenly distributed return holes 22 can make each part of it efficiently contact the atomized matrix flowing in from the liquid storage chamber 122, avoiding local saturation of the liquid suction component 30 while other areas are idle.

[0036] Under non-negative pressure conditions, excess atomized matrix in the suction element 30 can flow back to the storage chamber 122 evenly through each return hole 22, reducing the backflow lag caused by the concentrated return path, i.e., the atomized matrix may overflow due to gravity if it stays in the suction element 30 for too long.

[0037] The even distribution of multiple return holes 22 can reduce local stress concentration in the support 20. If the return holes 22 are concentrated, the structural strength of the corresponding area of ​​the support 20 will be weakened, and long-term use may lead to cracking due to vibration and temperature changes; the even distribution makes the support 20 more evenly stressed, improving the overall structural reliability.

[0038] In this embodiment, multiple reflux holes 22 are evenly distributed on a plane perpendicular to the length direction. This is a refined design around the atomizer's air intake channel 111. By optimizing the uniformity of the atomizing matrix flow, pressure balance, and component synergy efficiency, it forms triple protection with the spatial isolation of the housing 10 and the adsorption adjustment of the liquid suction component 30. This further solves the oil leakage problem under negative pressure environment, while ensuring the stability of the atomization effect and the durability of the product, ultimately improving the user's safety and comfort.

[0039] Optionally, in this embodiment of the application, the atomizer further has an atomizing airway 70, which is connected to the inhalation airway 111, and a plurality of return holes 22 are distributed around the axis of the atomizing airway 70.

[0040] In this embodiment, the atomizing airway 70 is the channel through which the atomizing matrix is ​​heated and atomized to form an aerosol. One end connects to the atomizing core (such as a heating component), and the other end connects to the inhalation airway 111, ultimately being inhaled by the user through the mouthpiece 11. It is the "core transmission path" of the atomization process. Multiple return holes 22 are formed on the support 20, evenly distributed in a ring or radial pattern around the axis of the atomizing airway 70. Each return hole 22 still maintains the basic function of connecting the liquid storage chamber 122 and the receiving space 121, but its distribution position forms a direct spatial relationship with the atomizing airway 70. The above design, through the spatial binding of the return holes 22 and the atomizing airway 70, further optimizes the transmission efficiency, leak-proof performance, and atomization stability of the atomizing matrix.

[0041] During inhalation, negative pressure is generated within the atomizing airway 70 due to airflow, and this negative pressure is radially distributed around the airway (the closer to the airway axis, the more significant the negative pressure effect). Return holes 22 are distributed around the axis of the atomizing airway 70, directly corresponding to the radiation range of the negative pressure. Through the synergistic effect of multiple holes, the negative pressure's influence on the liquid storage chamber 122 is dispersed. When the negative pressure is concentrated around the atomizing airway 70, the surrounding return holes 22 can evenly receive the negative pressure driving force, allowing the atomized matrix in the liquid storage chamber 122 to flow evenly into the receiving space 121 through each hole, where it is uniformly adsorbed by the suction element 30, avoiding impact-like flow of the atomized matrix caused by excessive unidirectional or localized negative pressure.

[0042] In non-inhalation mode, excess un-atomized atomized matrix in the suction element 30 needs to flow back to the storage chamber 122 through the return holes 22. Since the area near the atomizing air passage 70 in the suction element 30 is the main area of ​​atomized matrix consumption and residue, the surrounding return holes 22 can receive this residual atomized matrix at close range, shortening the return path and improving return efficiency. This avoids atomized matrix stagnation caused by the return holes 22 being far from the atomization core (residual atomized matrix accumulating at the edge of the suction element 30 and overflowing from the nozzle 11 due to gravity or vibration), reducing waste and lowering the risk of oil leakage.

[0043] In this embodiment, the above-mentioned arrangement represents a precise match between the atomizer's functional core (atomizing airway 70) and the return port 22. Through this coordinated spatial layout, efficient and directional supply of the atomizing matrix to the atomizing core is ensured, while pressure balancing and path optimization enhance leak-proof performance. Ultimately, this improves the atomizer's stability, safety, and user experience, reflecting a deep integration of structural design and functional requirements.

[0044] Optionally, in this embodiment of the application, the number of reflux holes 22 is three, and the interval between any two adjacent reflux holes 22 is the same.

[0045] In this embodiment, three return holes 22 on the support 20 are distributed on a plane perpendicular to the length of the atomizer, with the axis of the atomizing airway 70 as the center, and the central angle between any two adjacent return holes 22 is equal. The design of three equally spaced return holes 22 ensures both functional efficiency and structural stability. The equally spaced distribution of the three return holes 22 evenly distributes the atomizing matrix flowing from the liquid storage chamber 122 to the receiving space 121 into three flow channels. Compared to a single hole (which easily leads to concentrated liquid supply) or two holes (which may result in polarization), the three-hole design can more comprehensively cover the area of ​​the liquid suction component 30 around the atomizing airway 70, ensuring a balanced supply of atomizing matrix to each part of the liquid suction component 30. Under negative pressure, the atomizing matrix flows in synchronously through the three holes, preventing saturation and oil leakage in one direction of the liquid suction component 30 due to excessive liquid supply, or interruption of atomization due to insufficient liquid supply in one direction. This is particularly suitable for the uniform heating requirements of circular or annular atomizing cores.

[0046] During inhalation, the negative pressure around the atomizing airway 70 is distributed in a ring shape, and the three equally spaced return holes 22 can precisely correspond to the equilibrium dispersion point of the negative pressure field. The uniform spacing ensures that the negative pressure driving force borne by each hole is approximately equal, avoiding local pressure overload caused by hole concentration. When encountering abnormal negative pressure (such as violent inhalation or external environmental pressure fluctuations), the three holes work together to disperse the flow impact force of the atomizing matrix. Combined with the adsorption capacity of the liquid suction element 30, it can more efficiently buffer pressure pulses and reduce the risk of the atomizing matrix breaking through the barrier of the liquid suction element 30 due to excessive instantaneous pressure.

[0047] Under non-negative pressure conditions, un-atomized atomized matrix in the suction element 30 needs to flow back to the storage chamber 122 through the return hole 22. The layout of three equally spaced holes can cover the main residual area of ​​the suction element 30 (especially the annular area near the atomizing air channel 70), shortening the path length of the atomized matrix return. Compared to a larger number of holes (which may increase structural complexity), the three-hole design ensures return coverage while reducing the weakening of the support 20 by the channels; and compared to a smaller number of holes, the three holes can more comprehensively capture residual atomized matrix, avoiding atomized matrix retention due to insufficient return path.

[0048] It should be noted that the design of the three return holes 22 achieves an optimal balance between function and structure: fewer than three (e.g., 1-2) would result in insufficient functional coverage, while more than three (e.g., 4 or more) would increase the opening density of the bracket 20, potentially weakening its structural strength (especially when the thickness of the bracket 20 is limited). The symmetrical arrangement of the holes allows for more even stress distribution on the bracket 20, avoiding localized stress concentration caused by asymmetrical hole positions (e.g., cracks appearing around a particular hole after long-term use), thus extending the atomizer's lifespan.

[0049] In this embodiment, the arrangement of three equally spaced reflux holes 22 achieves balanced flow of the atomizing matrix, efficient pressure dispersion, and comprehensive reflux path, while also considering the structural strength and mass production feasibility of the support 20. This design, in conjunction with the surrounding layout of the atomizing airway 70 and the adsorption function of the liquid suction element 30, deeply synergizes to further enhance the leak-proof performance, atomization stability, and reliability of the atomizer, ultimately providing users with a superior experience.

[0050] Optionally, in this embodiment of the application, the liquid storage chamber 122 includes a first liquid storage chamber 40 and a second liquid storage chamber 50. Along the length direction of the atomizer, the first liquid storage chamber 40 is close to the nozzle 11, and the second liquid storage chamber 50 is disposed on the side of the first liquid storage chamber 40 away from the nozzle 11. The reflux hole 22 connects the first liquid storage chamber 40 and the accommodating space 121.

[0051] In this embodiment, the first liquid storage chamber 40 and the second liquid storage chamber 50 form a layered atomization matrix transport system. The first liquid storage chamber 40, located near the nozzle 11, serves as the "front-end chamber" for atomization matrix transport. It can quickly respond to inhalation negative pressure and promptly replenish the atomization matrix to the suction element 30, ensuring stable atomization output for the user upon inhalation. The second liquid storage chamber 50, acting as the "back-end chamber," stores the atomization matrix and is connected to the first liquid storage chamber 40 via a specific channel, continuously replenishing it with atomization matrix. This layered design achieves orderly transport of the atomization matrix, avoiding atomization interruptions due to insufficient atomization matrix in a single liquid storage chamber 122. Furthermore, by controlling the flow rate and pressure of the atomization matrix between the two chambers, the accuracy of atomization matrix transport is improved.

[0052] Furthermore, the structure of the first liquid storage chamber 40 and the second liquid storage chamber 50 can effectively buffer the impact of external negative pressure on the atomizing matrix. When the atomizer is in a negative pressure environment, the second liquid storage chamber 50, being far from the nozzle 11, experiences relatively weaker negative pressure and can act as a pressure buffer. The first liquid storage chamber 40, under the synergistic effect of the suction element 30 and the support 20, further weakens the negative pressure. The connecting structure between the two chambers can also dynamically adjust the internal pressure. When the pressure in the first liquid storage chamber 40 decreases due to suction negative pressure, the atomizing matrix in the second liquid storage chamber 50 is automatically replenished under the pressure difference, maintaining pressure balance between the two chambers and reducing the risk of atomizing matrix leakage caused by pressure fluctuations. Furthermore, the first liquid storage chamber 40 and the second liquid storage chamber 50 can store atomizing matrices of different compositions respectively, meeting diverse usage needs. For example, in medical nebulization scenarios, the first reservoir 40 can hold a drug solution, while the second reservoir 50 stores a diluent or auxiliary agent. Precise mixing can be achieved by controlling the release ratio of the two nebulizing substrates. In electronic nebulizers, nebulizing substrates with different flavors or ingredients can be stored, allowing users to switch between different reservoirs 122 for a diverse experience. Furthermore, the two nebulizing substrates can be mixed under specific conditions to achieve new nebulization effects.

[0053] In this embodiment, the arrangement of the first liquid storage chamber 40 and the second liquid storage chamber 50, combined with the physical barrier of the suction element 30 and the support 20, forms a more complete leak-proof system. The second liquid storage chamber 50, acting as a pressure buffer layer, effectively reduces the impact of negative pressure on the first liquid storage chamber 40 near the nozzle 11, reducing the driving force for the atomizing matrix to flow towards the nozzle 11. Under the adsorption effect of the suction element 30, the first liquid storage chamber 40 further prevents the atomizing matrix from overflowing. This allows the atomizer to maintain good sealing performance even in extreme negative pressure environments (such as high-altitude transportation or high-altitude use), preventing leakage and improving the user experience.

[0054] Optionally, in this embodiment of the application, the atomizer further includes a liquid guiding component 60, which is disposed between the first liquid storage chamber 40 and the second liquid storage chamber 50. The liquid guiding component 60 can guide the atomizing matrix from the first liquid storage chamber 40 to the second liquid storage chamber 50.

[0055] In this embodiment, the liquid guide 60, as a key component penetrating the first liquid storage chamber 40 and the second liquid storage chamber 50, acts as a channel for the flow of atomized matrix between the two chambers. Through its internal porous structure or special flow channel, it enables rapid and stable delivery of atomized matrix from the second liquid storage chamber 50 to the first liquid storage chamber 40. When the atomized matrix in the first liquid storage chamber 40 is consumed due to user inhalation, the liquid guide 60 can respond quickly, guiding the atomized matrix from the second liquid storage chamber 50 to the first liquid storage chamber 40, preventing the liquid level in the first liquid storage chamber 40 from becoming too low and ensuring the continuity of atomized matrix supply. Compared to relying solely on the connection structure between the two chambers, the intervention of the liquid guide 60 significantly improves the atomized matrix transmission efficiency and reduces resistance and delay during the atomized matrix transmission process.

[0056] Furthermore, the material and structural design of the liquid guide 60 endow it with the ability to control the flow of the atomizing matrix. By selecting materials with specific adsorption and permeability, the liquid guide 60 can adjust the transmission volume and speed of the atomizing matrix according to the pressure difference between the two chambers and the atomizing matrix requirements. For example, when the external negative pressure increases, the liquid guide 60 can automatically slow down the flow speed of the atomizing matrix to prevent the risk of overflow caused by the atomizing matrix flowing into the first liquid storage chamber 40 too quickly; while under normal use, it can ensure that an appropriate amount of atomizing matrix is ​​replenished in a timely manner. In addition, the liquid guide 60 can also achieve the mixing ratio control of atomizing matrices with different components (if the two chambers store different matrices) through its structural design, ensuring that the atomizing matrix enters the suction component 30 in a precise ratio, providing users with a stable atomization experience.

[0057] Furthermore, the liquid guide 60 is tightly disposed within the first liquid storage chamber 40 and the second liquid storage chamber 50, further enhancing the sealing performance of the atomizer. Its tight fit with the chambers reduces gaps that could lead to leakage of the atomizing matrix, forming an additional physical barrier layer between the two chambers. When the atomizer is in a negative pressure environment, the liquid guide 60 can help share some of the negative pressure. Through its own adsorption and buffering effect on the atomizing matrix, it reduces the direct impact of negative pressure on the atomizing matrix in the first and second liquid storage chambers 40 and 50. Together with the liquid suction component 30 in the first and second liquid storage chambers 40 and 50, it constructs a more comprehensive leak-proof system, effectively preventing the atomizing matrix from overflowing from the nozzle 11 or the chamber connection due to negative pressure.

[0058] In practical applications, the maximum liquid absorption capacity of the suction element 30 can be limited to within 40% of the volume of the first liquid storage chamber 40, providing a sufficient safety margin against leakage for the atomizer. When the atomizer is in a negative pressure environment or affected by external forces such as shaking or tilting, even if the suction element 30 is fully saturated with liquid, the amount of liquid it holds is still far less than the total capacity of the first liquid storage chamber 40. This means that most of the liquid is always retained in the first liquid storage chamber 40, preventing liquid from overflowing into the inhalation channel 111 or the mouthpiece 11 due to overload of the suction element 30.

[0059] The above parameter settings ensure a stable liquid transfer relationship between the suction element 30 and the first liquid storage chamber 40. Since the suction element 30 has a limited suction capacity, the liquid in the first liquid storage chamber 40 needs to be continuously and gradually replenished to the suction element 30 through structures such as the return hole 22, forming a dynamic balance of "on-demand supply." This mechanism avoids a large accumulation of liquid at the suction element 30 while ensuring that the suction element 30 has sufficient liquid for atomization when the user inhales. For example, during normal use, after the liquid adsorbed by the suction element 30 is consumed, the first liquid storage chamber 40 is slowly replenished through the return hole 22, maintaining the suction element 30 in an unsaturated state, ensuring continuous atomization while reducing the risk of liquid spillage.

[0060] Optionally, in this embodiment, the bracket 20 has a groove 21 on the side facing the suction nozzle 11, and the groove 21 engages at least part of the liquid suction member 30.

[0061] In this embodiment, the groove 21 provides a dedicated installation space for the liquid suction component 30, and securely fixes the liquid suction component 30 to the bracket 20 through a snap-fit ​​mechanism, effectively preventing displacement of the liquid suction component 30 due to vibration, external impact, or internal pressure changes during atomizer use. This precise positioning ensures that the liquid suction component 30 is always in the optimal working position, enabling it to stably perform its functions of adsorbing and transporting the atomized matrix. For example, during atomizer transportation or daily carrying by the user, even if it encounters bumps, the groove 21 can firmly hold the liquid suction component 30, maintaining its relative position with the liquid storage chamber 122 and the air intake channel 111, ensuring the stability of the atomized matrix transport path.

[0062] It should be noted that the shape and size of the groove 21 are closely matched with the liquid suction element 30, which can guide the atomized matrix to be evenly distributed between the liquid suction element 30 and the support 20, reducing the resistance to the flow of the atomized matrix. When the atomized matrix in the first liquid storage chamber 40 flows to the liquid suction element 30, the groove 21 can help the atomized matrix to more smoothly wet the surface of the liquid suction element 30, so that the liquid suction element 30 can quickly and fully absorb the atomized matrix. At the same time, the presence of the groove 21 limits the diffusion range of the atomized matrix, avoiding disordered flow or accumulation of the atomized matrix at the connection between the support 20 and the liquid suction element 30, ensuring that the atomized matrix can be efficiently and orderly adsorbed by the liquid suction element 30 and transported to the intake airway 111, thereby improving the overall atomization efficiency.

[0063] Furthermore, the snap-fit ​​between the groove 21 and the suction element 30 forms an additional sealing barrier. After the suction element 30 is embedded in the groove 21, the two fit tightly together, effectively reducing gaps that could lead to leakage of the atomizing matrix and preventing the atomizing matrix in the storage chamber 122 from seeping out from the connection between the support 20 and the suction element 30. Under negative pressure, the groove 21 further enhances the buffering effect of the suction element 30 against negative pressure, preventing negative pressure from directly acting on the connection between the storage chamber 122 and the suction element 30, reducing the risk of the atomizing matrix overflowing from this location due to pressure difference. Working in conjunction with the suction element 30, the liquid guide 60, and other components, the groove 21 collectively constructs a more robust leak-proof system, improving the sealing performance of the atomizer in complex environments.

[0064] Optionally, in this embodiment of the application, the liquid suction member 30 includes a first liquid suction part 31 and a second liquid suction part 32. At least a portion of the first liquid suction part 31 is connected to the groove 21, and the second liquid suction part 32 is disposed on the side of the first liquid suction part 31 near the suction nozzle 11. The first liquid suction part 31 has at least one through hole 311, and the through hole 311 and the return hole 22 are correspondingly disposed.

[0065] In this embodiment, the through-hole 311 of the first liquid absorption section 31 is correspondingly arranged with the return hole 22 of the support 20, forming a highly efficient atomized matrix transmission channel under negative pressure. When the user inhales and generates negative pressure, the atomized matrix in the first liquid storage chamber 40 flows rapidly into the first liquid absorption section 31 through the return hole 22 and the through-hole 311; while the second liquid absorption section 32, due to the absence of the through-hole 311, only adsorbs the atomized matrix transferred by the first liquid absorption section 31 through contact, forming a "first introduce, then distribute" layered transmission mechanism. This design avoids the atomized matrix directly impacting the inhalation airway 111, ensuring that the atomized matrix enters the receiving space 121 at a stable flow rate.

[0066] Furthermore, the structural differences between the first liquid absorption section 31 and the second liquid absorption section 32 endow the liquid absorption component 30 with a gradient atomized matrix adsorption capacity. The first liquid absorption section 31, connected to the return hole 22 via the through hole 311, can quickly absorb a large amount of atomized matrix, acting as a "buffer layer" for atomized matrix transport. The second liquid absorption section 32, lacking the through hole 311, requires the atomized matrix to be slowly absorbed through the permeation of the first liquid absorption section 31. Its adsorption rate and capacity are both lower than those of the first liquid absorption section 31, thus becoming a "safety layer" to prevent atomized matrix overflow. Under normal conditions, the second liquid absorption section 32 can intercept excess atomized matrix from the first liquid absorption section 31, preventing it from flowing directly to the nozzle 11. During sudden changes in negative pressure, the low permeability of the second liquid absorption section 32 can slow down the flow rate of the atomized matrix. Combined with the atomized matrix return mechanism of the return hole 22, this provides double protection against leakage of the atomized matrix from the nozzle 11.

[0067] In this embodiment, the first suction section 31 and the second suction section 32, in conjunction with the return hole 22, construct a multi-layered leak-proof system. The second suction section 32, acting as the last line of defense, intercepts excess atomized matrix caused by pressure fluctuations or excessive absorption of the atomizing matrix by the first suction section 31, preventing it from flowing to the nozzle 11. Simultaneously, the cooperation between the through hole 311 and the return hole 22 enables bidirectional flow of the atomized matrix, allowing for timely recovery of residual atomized matrix when not in use, further reducing the risk of leakage. This design ensures the atomizer maintains good sealing even during transportation, tilting, or extreme negative pressure environments, reducing equipment damage and cleaning / maintenance costs due to leakage.

[0068] In practical applications, the opening area of ​​the through hole 311 can be greater than or equal to the opening area of ​​the return hole 22, ensuring that the atomized matrix flows unobstructed from the first liquid storage chamber 40 to the suction element 30. When the atomizer is under negative pressure, the atomized matrix in the first liquid storage chamber 40 enters the receiving space 121 through the return hole 22. Because the through hole 311 has a larger area, it can quickly receive and guide the atomized matrix into the first suction part 31. This design avoids the accumulation of atomized matrix at the suction element 30 due to the excessively large area of ​​the return hole 22 and the excessively fast flow rate of the atomized matrix, while also preventing the formation of a bottleneck in the transmission of atomized matrix due to the excessively small area of ​​the through hole 311.

[0069] Furthermore, the parameter settings for the opening areas of the through hole 311 and the return hole 22 help maintain the pressure balance between the first liquid storage chamber 40 and the receiving space 121, while enhancing the leak-proof performance. Under negative pressure, the return hole 22 serves as the inflow channel for the atomized matrix. The smaller opening area limits the amount of atomized matrix that rushes in instantly, preventing a sudden drop in pressure within the first liquid storage chamber 40. Meanwhile, the through hole 311, while receiving the atomized matrix, allows gas to flow in reverse to balance the pressure, preventing abnormal flow of the atomized matrix due to excessive internal and external pressure differences. Under normal conditions, when the atomized matrix in the suction element 30 needs to flow back to the first liquid storage chamber 40 through the return hole 22, the smaller area of ​​the return hole 22 slows down the return speed of the atomized matrix, preventing the rapid backflow of the atomized matrix from impacting the first liquid storage chamber 40 and causing splashing. Combined with the adsorption characteristics of the suction element 30, this parameter setting further reduces the risk of the atomized matrix overflowing from the nozzle 11.

[0070] Furthermore, the aforementioned parameter relationships are closely coordinated with the layered structure of the liquid suction component 30 (first liquid suction section 31 and second liquid suction section 32) to achieve precise control of the atomized matrix flow rate. The through holes 311 of the first liquid suction section 31 correspond to the return holes 22. The larger area of ​​the through holes 311 ensures efficient introduction of the atomized matrix, while the relatively small area of ​​the return holes 22 limits the amount of atomized matrix transported in a single flow, resulting in a uniform distribution of the atomized matrix in the first liquid suction section 31. The second liquid suction section 32 further refines the atomized matrix transport path by contacting and adsorbing the atomized matrix of the first liquid suction section 31.

[0071] Optionally, in this embodiment, the projection of the reflux hole 22 is within the projection range of the through hole 311 along the length direction of the atomizer.

[0072] In this embodiment, the projection of the return hole 22 falls within the projection range of the through hole 311, ensuring that the atomized matrix, after flowing out of the first liquid storage chamber 40 through the return hole 22, can accurately and efficiently enter the through hole 311 and be absorbed by the suction element 30. This precise spatial correspondence avoids leakage or waste of the atomized matrix due to path deviation during transmission. When the atomizer is under negative pressure, the atomized matrix in the first liquid storage chamber 40 flows vertically to the through hole 311 through the return hole 22, reducing the diffusion and loss of the atomized matrix in the gap between the support 20 and the suction element 30, allowing the atomized matrix to be directly and quickly captured by the first suction part 31, thus preventing leakage of the atomized matrix.
