Atomizer and atomization device

Abstract

The application is suitable for the technical field of aerosol generating equipment, and provides an atomizer and an atomization device. The atomizer comprises: a liquid storage bin having a liquid injection hole; a blocking piece movably arranged in the liquid storage bin and blocking the liquid injection hole; and a force applying piece arranged in the liquid storage bin and applying a pushing force to the blocking piece in a direction towards the liquid injection hole. The blocking piece is designed in a built-in manner and is accommodated in the interior of the liquid storage bin instead of an exposed structure. A special tool (such as a liquid injection needle) needs to be used to overcome the pushing force applied by the force applying piece during a liquid injection operation, so as to open the liquid injection hole. This structural design not only increases the force threshold, so that children cannot apply sufficient force to push the blocking piece, but also hides the exposed operation structure, so that children cannot easily find the operation path, effectively preventing accidental touch and improving the safety of use. In addition, the liquid injection plug is avoided to be arranged on the outer surface of the liquid storage bin, and the appearance of the atomizer is improved.

Description

Technical Field

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

[0002] In related technologies, an atomizer includes a reservoir and an injection plug, with the reservoir having an injection port for injecting an aerosol matrix. When the atomizer is in use, the injection plug seals the injection port of the reservoir; when the atomizer needs to inject an aerosol matrix, the injection plug is opened, and liquid is injected into the reservoir through the injection port.

[0003] However, when children come into contact with the nebulizer, they can easily pry open the liquid filling plug with their hands, thus coming into contact with the aerosol in the liquid reservoir, which poses a certain safety hazard to the nebulizer. Utility Model Content

[0004] The purpose of this application is to provide an atomizer and atomizing device, which aims to solve the technical problem that the liquid filling plug of the atomizer is easily pried open in the related art.

[0005] To achieve the above objectives, according to one aspect of this application, an atomizer is provided, comprising: a liquid reservoir having an injection port; a sealing member movably disposed within the liquid reservoir and sealing the injection port; and a force-applying member disposed within the liquid reservoir for applying a thrust toward the injection port to the sealing member.

[0006] Optionally, the sealing component includes a sealing body and a guide body. The sealing body seals the injection hole, and the guide body is located on the side of the sealing body away from the injection hole. A guide structure is provided inside the liquid storage tank, and a guide hole is provided on the guide structure. The guide body slides through the guide hole.

[0007] Optionally, the force-applying component is fitted onto the guide body, with both ends of the force-applying component contacting the sealing body and the guide structure, respectively.

[0008] Optionally, a positioning element is provided on the surface of the sealing element near the injection hole, and the positioning element has a positioning groove for the injection structure to be inserted.

[0009] Optionally, the positioning element includes multiple positioning blocks, which are spaced apart circumferentially along the sealing element and surround a positioning groove; there is a liquid guiding gap between two positioning blocks spaced apart circumferentially along the sealing element, and the liquid guiding gap communicates with the positioning groove.

[0010] Optionally, the surface of the positioning block near the positioning groove is a guide slope, the end of the positioning block away from the sealing member is the first end, the end of the positioning block near the sealing member is the second end, and the guide slope is inclined from the first end to the second end towards the positioning groove.

[0011] Optionally, the atomizer also includes a sealing tube that is interference-fitted into the injection port and a portion of the sealing tube extends into the reservoir; a sealing body covers the sealing tube and abuts against it.

[0012] Optionally, a sealing gasket is provided on the surface of the sealing body away from the guide body, the sealing gasket covering the sealing tube and abutting against the sealing tube.

[0013] Optionally, the surface of the sealing body near the injection hole is provided with an installation groove, and the sealing gasket is embedded in the installation groove.

[0014] Optionally, the liquid storage tank has a suction nozzle surface, and the injection hole is disposed on the surface of the liquid storage tank that is adjacent to or opposite to the suction nozzle surface.

[0015] According to another aspect of this application, an atomizing device is provided, including a power supply component and the aforementioned atomizer, wherein the power supply component is electrically connected to the atomizer.

[0016] The beneficial effects of the nebulizer provided in this application are as follows: the sealing component adopts a built-in design, housed inside the liquid reservoir rather than being an exposed structure; during liquid injection, a special tool (such as an injection needle) is required to overcome the pushing force applied by the force-applying component in order to open the injection port. This structural design not only increases the force threshold, making it difficult for children to apply sufficient force to push the sealing component, but also conceals the exposed operating structure, making it difficult for children to easily find the operating path, effectively preventing accidental activation and improving safety during use. Furthermore, it avoids the need for an injection plug on the outer surface of the liquid reservoir, improving the nebulizer's aesthetics.

[0017] Meanwhile, the force-applying component continuously applies a restoring force to the sealing component, so that even if the atomizer is tilted or shaken, the sealing component can stably seal the injection hole, thereby reducing the risk of leakage.

[0018] In addition, the force-applying components are located inside the liquid storage tank, which not only makes them less susceptible to external impacts, dust, or liquid corrosion, effectively extending their service life, but also ensures the purity of the aerosol matrix inside the liquid storage tank.

[0033] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0034] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly or indirectly on that other element. When an element is referred to as being "connected to" another element, it can be directly or indirectly connected to that other element. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0036] In the description of this application, unless otherwise stated, " / " indicates that the objects before and after are in an "or" relationship. For example, A / B can mean A or B. "And / or" in this application is merely a description of the relationship between the related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone. A and B can be singular or plural.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0038] As described in the background section, in related technologies, an atomizer includes a reservoir and a plug, with the reservoir having an injection port for injecting an aerosol matrix. When the atomizer is in use, the plug seals the injection port of the reservoir; when the atomizer needs to inject the aerosol matrix, the plug is opened, and the aerosol is injected into the reservoir through the injection port. However, when children come into contact with the atomizer, they can easily pry open the plug with their hands, thus coming into contact with the aerosol inside the reservoir, posing a certain safety hazard.

[0039] Reference Figures 1 to 6To address the aforementioned problems, according to one aspect of this application, an embodiment of this application provides an atomizer. The atomizer includes a liquid storage chamber 100, a sealing member 200, and a force-applying member 300. The liquid storage chamber 100 has an injection hole 110. The sealing member 200 is movably disposed within the liquid storage chamber 100 and seals the injection hole 110. The force-applying member 300 is disposed within the liquid storage chamber 100 and is used to apply a thrust toward the injection hole 110 to the sealing member 200.

[0040] In this embodiment, the injection hole 110 is disposed on the outer surface of the storage tank 100 and extends into the interior of the storage tank 100. The sealing member 200 is a sealing plug or a sealing column, and has a sealing position and an injection position. When the sealing member 200 is in the sealing position, the sealing member 200 completely seals the injection hole 110 to prevent the aerosol matrix in the storage tank 100 from leaking outward. When the sealing member 200 is in the injection position, there is an injection gap between the surface of the sealing member 200 near the injection hole 110 and the inner wall surface of the storage tank 100 where the injection hole 110 is provided, allowing the external aerosol matrix to flow into the storage tank 100. The sealing member 200 switches from the sealing position to the injection position by applying a thrust toward the storage tank 100 through the injection needle of the injection bottle. In addition, the sealing component 200 can switch between the sealing position and the liquid injection position by providing two mutually magnetically attracted structures on its own surface and the inner wall of the liquid storage tank 100.

[0041] The force-applying component 300 can be a helical spring, an elastic sheet, elastic silicone, a magnetic structure, or a shape memory alloy spring. The force-applying component 300 is located inside the liquid storage chamber 100, which means that the force-applying component 300 is in direct contact with the aerosol matrix inside the liquid storage chamber 100. That is, the force-applying component 300 is immersed in the aerosol matrix inside the liquid storage chamber 100. The force-applying component 300 is used to push the sealing component 200 from the liquid injection position to the sealing position.

[0042] The sealing element 200 is a built-in design, housed inside the liquid reservoir 100 rather than being exposed. During injection, a special tool (such as an injection needle) must be used to overcome the thrust applied by the force-applying element 300 to open the injection port 110. This design not only increases the force threshold, making it difficult for children to apply sufficient force to push the sealing element 200, but also conceals the exposed operating structure, preventing children from easily finding the operating path, effectively preventing accidental activation, and improving safety. Furthermore, it avoids the need for an injection plug on the outer surface of the liquid reservoir 100, improving the atomizer's aesthetics.

[0043] Meanwhile, the force-applying component 300 continuously applies a restoring force to the sealing component 200, so that even if the atomizer is tilted or shaken, the sealing component 200 can stably seal the injection hole 110, thereby reducing the risk of leakage.

[0044] In addition, the force-applying component 300 is installed inside the liquid storage tank 100, which not only makes it less susceptible to external impacts, dust or liquid corrosion, effectively extending its service life, but also ensures the purity of the aerosol matrix inside the liquid storage tank 100.

[0045] Reference Figure 2 as well as Figures 4 to 6 In one embodiment, the sealing component 200 includes a sealing body 210 and a guide body 220. The sealing body 210 seals the injection hole 110, and the guide body 220 is disposed on the side of the sealing body 210 away from the injection hole 110. A guide structure 120 is provided in the liquid storage tank 100, and a guide hole 121 is provided on the guide structure 120. The guide body 220 slides through the guide hole 121.

[0046] In this embodiment, the sealing body 210 can be inserted into the injection hole 110 by interference fit to seal the injection hole 110, or it can be completely covered and fitted to the inner wall surface of the storage tank 100 where the injection hole 110 is provided. The guide body 220 is a guide post, and the guide body 220 is coaxially arranged with the sealing body 210. The guide structure 120 is a guide bracket or guide rod, and the entire structure of the guide structure 120 is located inside the storage tank 100. The extension direction of the guide hole 121 is parallel to the extension direction of the injection hole 110, and the guide body 220 is slidably disposed in the guide hole 121 along the extension direction of the guide hole 121.

[0047] The guide body 220 slides through the guide hole 121, forming a guiding constraint and limiting the displacement of the sealing body 210 within the liquid storage tank 100 (such as swaying left and right or tilting). Regardless of whether the thrust direction of the force-applying component 300 is completely centered (such as slightly tilted), or whether the atomizer is tilted or vibrating, the guide structure 120 can forcibly constrain the movement trajectory of the sealing body 210 through the guide body 220, ensuring that it is always aligned with the injection hole 110, thus avoiding sealing failure due to misalignment.

[0048] Meanwhile, during injection, a special tool (such as an injection needle) pushes the sealing body 210, and the guide body 220 slides in the guide hole 121, providing a linear trajectory constraint for the retraction movement of the sealing component 200, thus preventing the sealing component 200 from getting stuck or shifting.

[0049] Reference Figure 5 In one embodiment, the force-applying element 300 is sleeved on the guide body 220, and both ends of the force-applying element 300 contact the sealing body 210 and the guide structure 120, respectively. In this embodiment, the force-applying element 300 is a force-applying spring.

[0050] The guide body 220 not only provides an installation reference for the force-applying component 300, but also allows the force-applying component 300 to automatically position itself between the sealing body 210 and the guide structure 120 during assembly, simply by inserting the guide body 220 into the guide hole 121, thus determining its axial position without the need for additional positioning structures. Furthermore, the force-applying component 300 can actively push the sealing body 210 towards the injection hole 110 after injection, thereby sealing the injection hole 110 and achieving automatic reset.

[0051] Reference Figure 2 as well as Figures 4 to 8 In one embodiment, a positioning element 400 is provided on the surface of the sealing element 200 near the injection hole 110, and the positioning element 400 has a positioning groove 420 for the injection structure to be inserted.

[0052] In this embodiment, the positioning element 400 is disposed on the surface of the sealing body 210 away from the guide body 220, and the liquid injection structure refers to the liquid injection needle or other tip structure of the liquid injection bottle. The positioning groove 420 is disposed along the axial direction of the positioning element 400.

[0053] When injecting liquid into the storage tank 100, the injection structure is aligned and inserted into the positioning groove 420, and then the sealing member 200 is pushed to move into the storage tank 100, so that an injection gap is generated between the sealing member 200 and the inner wall surface of the storage tank 100 where the injection hole 110 is provided, thereby completing the injection operation.

[0054] The positioning groove 420 provides a precise insertion guide for the injection structure (such as the injection needle), enabling the injection structure to quickly align with the force center of the sealing component 200, thus improving the convenience and stability of the injection operation.

[0055] Reference Figure 2 as well as Figures 5 to 8 In one embodiment, the positioning member 400 includes a plurality of positioning blocks 410, which are spaced apart circumferentially along the sealing member 200 and surround a positioning groove 420; there is a liquid guiding gap 430 between two positioning blocks 410 spaced apart circumferentially along the sealing member 200, and the liquid guiding gap 430 communicates with the positioning groove 420.

[0056] In this embodiment, multiple positioning blocks 410 are evenly spaced along the circumference of the sealing body 210, and the bottom of the positioning groove 420 is the surface of the sealing body 210 away from the guide body 220. The bottom wall of the liquid guiding gap 430 is the surface of the sealing body 210 away from the guide body 220; it can be understood that the width, depth or length of each liquid guiding gap 430 may also be different.

[0057] The injection structure pushes the sealing component 200 toward the liquid storage tank 100. When an injection gap is formed between the sealing component 200 and the inner wall surface of the liquid storage tank 100 with the injection hole 110, the aerosol matrix in the injection bottle will first flow into the positioning groove 420 and the liquid guiding gap 430 connected to it through the injection structure. With the diversion effect of the liquid guiding gap 430, the risk of local liquid accumulation caused by the blocking of the positioning block 410 is effectively reduced. Then, it is injected into the liquid storage tank 100 through the injection gap.

[0058] Meanwhile, after the injection structure (such as the injection needle) is inserted into the positioning groove 420, the surrounding positioning blocks 410 can form a circumferential constraint, preventing the injection structure from deflecting or tilting, ensuring that it is always aligned with the force center of the sealing component 200, and ensuring that the pushing and injection process is stable and reliable.

[0059] In addition, the positioning component 400 adopts a split design with multiple positioning blocks 410, which can reduce the amount of material used and reduce production costs while ensuring structural strength.

[0060] Reference Figure 2 as well as Figures 5 to 8 In one embodiment, the surface of the positioning block 410 near the positioning groove 420 is a guide slope 411, the end of the positioning block 410 away from the sealing member 200 is the first end, and the end of the positioning block 410 near the sealing member 200 is the second end. The guide slope 411 is inclined from the first end to the second end towards the positioning groove 420.

[0061] In this embodiment, the guide slope 411 is a smoothly transitioned arc surface. It can be understood that the guide slope 411 can also be a flat straight surface.

[0062] The guide slope 411 forms a tapered positioning channel that is wider on the outside and narrower on the inside, which serves as a guide and can guide the liquid injection structure to quickly align and slide into the positioning groove 420. This effectively reduces insertion jamming caused by initial alignment deviation and significantly improves the convenience and smoothness of operation.

[0063] Reference Figure 2 as well as Figures 5 to 8 In one embodiment, the positioning element 400 and the sealing element 200 are integrally molded. In this embodiment, the positioning element 400 and the sealing element 200 can be molded by integral injection molding, 3D printing or other integral molding methods.

[0064] The above structural design not only helps to enhance the structural strength and durability of the positioning component 400 and the sealing component 200, but also simplifies the production process and reduces costs.

[0065] Reference Figure 5 as well as Figure 6In one embodiment, the atomizer further includes a sealing tube 500, which is inserted into the injection hole 110 with an interference fit, and a portion of the structure of the sealing tube 500 extends into the liquid storage chamber 100; the sealing body 210 covers the sealing tube 500 and abuts against the sealing tube 500.

[0066] In this embodiment, the sealing tube 500 is a capillary stainless steel tube. It is understood that the sealing tube 500 can also be other metal tubes or rigid plastic tubes. The sealing body 210 completely covers the sealing tube 500 and keeps it in contact with the sealing tube 500. In addition, the guide body 220 is coaxially arranged with the sealing body 210, and the diameter of the guide body 220 is smaller than the diameter of the sealing body 210.

[0067] The sealing tube 500 is inserted into the injection hole 110 with an interference fit. It can fill any tiny gaps that may exist in the processing of the injection hole 110 through its own deformation, forming the first sealing barrier to prevent the aerosol matrix in the liquid storage tank 100 from flowing out through the gap between the sealing tube 500 and the wall of the injection hole 110.

[0068] Meanwhile, the portion of the sealing tube 500 extending into the liquid storage tank 100 forms a protruding sealing platform. When the sealing body 210 covers and presses against this structure, the contact position is more defined and the outline is more regular, avoiding edge misalignment that may occur when the sealing component 200 directly contacts the inner wall of the liquid storage tank 100. This provides a stable sealing reference for the sealing component 200 and ensures reliable sealing.

[0069] In addition, during liquid injection, the sealing component 200 moves with the liquid injection structure and will rub against the sealing tube 500, rather than directly wearing down the wall of the injection hole 110. As a vulnerable part, the sealing tube 500 can be replaced separately, which reduces the risk of having to replace the entire liquid storage tank 100 due to wear of the wall of the injection hole 110, and reduces maintenance costs.

[0070] Reference Figure 5 In one embodiment, a sealing gasket 230 is provided on the surface of the sealing body 210 away from the guide body 220, the sealing gasket 230 covers the sealing tube 500 and abuts against the sealing tube 500.

[0071] In this embodiment, the sealing gasket 230 is a silicone gasket. It is understood that the sealing gasket 230 can also be a rubber gasket; the sealing gasket 230 completely covers the sealing tube 500.

[0072] The sealing gasket 230 not only deforms slightly according to the contour of the sealing tube 500, filling the gap between the sealing body 210 and the end of the sealing tube 500, thus enhancing the sealing performance and reducing the risk of leakage, but also, as an intermediate buffer layer, prevents the sealing body 210 from directly contacting the sealing tube 500, thereby avoiding rigid friction or collision and extending the service life of both the sealing tube 500 and the sealing body 210.

[0073] Reference Figure 5 as well as Figure 6 In one embodiment, the sealing body 210 has an installation groove 211 on its surface near the injection hole 110, and the sealing gasket 230 is embedded in the installation groove 211.

[0074] In this embodiment, the surface of the sealing gasket 230 away from the guide body 220 is flush with the surface of the sealing body 210 away from the guide body 220, or the surface of the sealing gasket 230 away from the guide body 220 is located on the side of the surface of the sealing body 210 away from the guide body 220. The peripheral surface of the sealing gasket 230 is flush with the peripheral surface of the sealing body 210, or the peripheral surface of the sealing gasket 230 is located on the side of the peripheral surface of the sealing body 210 away from the axis of the sealing body 210. Furthermore, the sealing gasket 230 and the sealing body 210 are integrally formed or connected by adhesive bonding, nesting, or other methods.

[0075] After the injection is completed, the sealing body 210 moves towards the injection hole 110 under the action of the force-applying component 300 until the sealing gasket 230 and the sealing tube 500 are tightly pressed together. Only then is the entire injection operation considered complete. The mounting groove 211 not only provides a clear circumferential and axial positioning boundary for the sealing gasket 230, reducing the risk of the sealing gasket 230 shifting during assembly or use, but also ensures the reliable performance of its sealing function. At the same time, the nesting method enhances the connection strength between the sealing gasket 230 and the sealing body 210, reducing the risk of the sealing gasket 230 falling off due to long-term compression and friction. In addition, it reduces the overall axial dimension of the sealing component 200, contributing to a compact layout.

[0076] Reference Figure 5 In one embodiment, a weight-reducing groove 212 is provided on the surface of the sealing body 210 near the guide body 220.

[0077] The weight-reducing groove 212 not only reduces the weight of the sealing component 200 itself and reduces the external force required to move the sealing component 200 during liquid injection, making the liquid injection operation easier and smoother; at the same time, it can also reduce the amount of material used in the sealing component 200, reducing manufacturing costs while ensuring structural strength.

[0078] Reference Figures 1 to 4 In one embodiment, the liquid storage tank 100 has a suction nozzle surface 130, and an injection hole 110 is disposed on the surface of the liquid storage tank 100 that is adjacent to or opposite to the suction nozzle surface 130.

[0079] In this embodiment, a suction nozzle hole 131 is provided on the suction nozzle surface 130, and a liquid injection hole 110 is provided on the side of the liquid storage tank adjacent to the suction nozzle surface 130, so as to facilitate visual inspection by the user and improve the convenience of liquid injection operation. It can be understood that the liquid injection hole 110 can also be provided on the bottom surface of the liquid storage tank 100 opposite to the suction nozzle surface 130.

[0080] The mouthpiece surface 130 is the contact area for the user when sucking. The liquid injection hole 110 is positioned away from the mouthpiece surface 130 to prevent accidental liquid splashing onto the mouthpiece surface 130 during injection, reducing the risk of the user coming into contact with residual liquid and improving hygiene. At the same time, the positioning of the liquid injection hole 110 away from the mouthpiece surface 130 reduces the probability of children or non-users accidentally touching the liquid injection hole 110.

[0081] Reference Figures 1 to 4 In one embodiment, the atomizer further includes an atomizing core 600, a bottom cover 700, a mounting bracket 800 covered with sealing silicone, and two electrodes 900. The atomizing core 600 is disposed within the liquid storage chamber 100 and communicates with the mouthpiece opening 131. A portion of the bottom cover 700 is fixedly inserted into the liquid storage chamber 100 to seal the opening on the bottom surface of the liquid storage chamber 100 opposite to the mouthpiece surface 130. The mounting bracket 800 is disposed on the side of the bottom cover 700 near the mouthpiece surface 130 and abuts against the inner wall of the liquid storage chamber 100. The atomizing core 600 and the guide structure 120 are both disposed on the mounting bracket 800. The two electrodes 900 are spaced apart, with a portion of the electrode 900 disposed on the bottom cover 700 and the other portion disposed on the mounting bracket 800, and electrically connected to the atomizing core 600.

[0082] Reference Figures 1 to 8 According to another aspect of this application, embodiments of this application also provide an atomizing device, which includes a power supply component and the aforementioned atomizer, wherein the power supply component is electrically connected to the atomizer.

[0083] In this embodiment of the application, the power supply component is a power supply battery, which is electrically connected to the atomizing core 600 in the atomizer to supply power to the atomizing core 600.

[0084] The sealing element 200 is a built-in design, housed inside the liquid reservoir 100 rather than being exposed. During injection, a special tool (such as an injection needle) must be used to overcome the thrust applied by the force-applying element 300 to open the injection port 110. This design not only increases the force threshold, making it difficult for children to apply sufficient force to push the sealing element 200, but also conceals the exposed operating structure, preventing children from easily finding the operating path, effectively preventing accidental activation, and improving safety. Furthermore, it avoids the need for an injection plug on the outer surface of the liquid reservoir 100, improving the atomizer's aesthetics.

[0085] In summary, implementing the nebulizer and nebulizing device provided in this embodiment has at least the following beneficial technical effects: the sealing element 200 adopts a built-in design, housed inside the liquid storage chamber 100 rather than being an exposed structure; during liquid injection, a special tool (such as an injection needle) is required to overcome the pushing force applied by the force-applying element 300 in order to open the injection hole 110. This structural design not only increases the force threshold, making it difficult for children to apply sufficient force to push the sealing element 200; it also hides the exposed operating structure, making it difficult for children to easily find the operating path, effectively preventing accidental contact and improving safety during use; and it also avoids the need for an injection plug on the outer surface of the liquid storage chamber 100, improving the aesthetics of the nebulizer.

[0086] Meanwhile, the force-applying component 300 continuously applies a restoring force to the sealing component 200, so that even if the atomizer is tilted or shaken, the sealing component 200 can stably seal the injection hole 110, thereby reducing the risk of leakage.

[0087] In addition, the force-applying component 300 is installed inside the liquid storage tank 100, which not only makes it less susceptible to external impacts, dust or liquid corrosion, effectively extending its service life, but also ensures the purity of the aerosol matrix inside the liquid storage tank 100.

[0088] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
