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] The atomizer in an atomizing device is the component that generates aerosols. An atomizer generally includes a mouthpiece, a fuel tank housing, an atomizing coil, and a base. The fuel tank housing stores the atomizing matrix, and the atomizing coil heats and atomizes the atomizing matrix. The fuel tank housing has a filling hole for adding the atomizing matrix into the fuel tank housing.

[0003] In related technologies, when the nozzle and the oil tank housing are integrally formed, the injection hole is generally located on the side or bottom of the oil tank housing. In practical applications, the injection hole is sealed with an injection plug, but this simple sealing method is easily opened by accident, causing the atomizing matrix to flow out. Furthermore, after filling the oil tank through the injection hole and before closing the injection plug, there is a high probability that the atomizing matrix will flow out from the injection hole, affecting the user experience.

[0004] To address these issues, prior art typically involves adding a silicone film at the injection hole. However, after multiple injections, the silicone film is prone to breakage and failure. Additionally, other components are required, resulting in a complex structure and higher costs. Utility Model Content

[0005] The purpose of this application is to provide an atomizer and atomizing device that can solve at least some of the above-mentioned problems.

[0006] To solve the above-mentioned technical problems, this application is implemented as follows:

[0007] In a first aspect, embodiments of this application provide an atomizer, including a housing assembly, a base assembly, and a sealing element. The housing assembly and the base assembly are configured to form a receiving cavity. The housing assembly has an injection hole that communicates with the receiving cavity. The sealing element includes a plugging portion that is flexible and deformable. The plugging portion is configured to abut against the inner wall of the housing assembly and block the injection hole, and can unseal the injection hole under stress.

[0008] In this embodiment, the sealing portion of the sealant, in its natural state, flexibly deforms to adhere tightly to the inner wall of the housing assembly, forming an initial seal on the injection hole. This pre-pressurized contact immediately prevents the spontaneous outflow of the atomized matrix after injection. During injection, if the external injection pressure (e.g., syringe thrust) exceeds the critical deformation force of the sealant, the sealing portion undergoes elastic deformation, temporarily detaching from the inner wall and opening the injection hole. After the injection is completed and the pressure is removed, the sealant automatically resets due to material rebound force, resealing the injection hole. This embodiment automatically seals the injection hole immediately after injection, eliminating the need for the physical operation time of installing the injection plug, completely eliminating the time window of "leakage before injection plug installation" in traditional designs. It also reduces the need for components such as silicone membranes, resulting in improved user experience and reduced product costs.

[0009] Optionally, in this embodiment, the seal further includes a body portion, which is sealed between the housing assembly and the base assembly, and the body portion is connected to the sealing portion.

[0013] Optionally, in this embodiment of the application, the size of the blocking portion gradually decreases along the second direction from the first end to the second end.

[0017] Secondly, in this application embodiment, an atomizing device is also provided, including: an atomizer as described above; a power supply component; the power supply component is electrically connected to the atomizer to provide an operating voltage for the atomizer.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. 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.

[0025] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. 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 Figs. 1 to 4The embodiments of this application provide an atomizer, including a housing assembly 10, a base assembly 20, and a sealing member 30. The housing assembly 10 and the base assembly 20 are enclosed to form a receiving cavity 40. The housing assembly 10 has an injection hole 111, which communicates with the receiving cavity 40. The sealing member 30 includes a blocking part 31, which is flexible and deformable. The blocking part 31 is configured to abut against the inner wall of the assembly 10 and block the injection hole 111, and can be unsealed under stress.

[0028] In this embodiment, the sealing portion 31 of the seal 30, in its natural state, flexibly deforms to adhere tightly to the inner wall of the housing assembly 10, forming an initial seal on the injection hole 111. This pre-pressurized contact can immediately prevent the spontaneous outflow of the atomized matrix after injection. During injection, if the external injection pressure (such as syringe thrust) > the critical deformation force of the seal 30, the sealing portion 31 undergoes elastic deformation and temporarily detaches from the inner wall, opening the injection hole 111. After the injection ends and the pressure is removed, the seal 30 automatically resets due to the material's rebound force, resealing the injection hole 111. This embodiment automatically seals the injection hole 111 immediately after injection, eliminating the need for the physical operation time of installing the injection plug 12, completely eliminating the time window of "leakage before installation of the injection plug 12" in traditional designs. It also reduces the need for components such as silicone films, resulting in improved user experience and reduced product costs.

[0029] Optionally, in this embodiment, the seal 30 further includes a body portion 32, which is sealed between the housing assembly 10 and the base assembly 20, and the body portion 32 is connected to the sealing portion 31.

[0030] In this embodiment, the body part 32 is fixed between the housing assembly 10 and the base by an interference fit or a hot-melt process, forming a permanent leak-proof barrier that isolates the receiving cavity 40 from the outside. The sealing part 31, as a movable component, controls the opening and closing of the injection hole 111 through flexible deformation, responding to changes in injection pressure. The connection between the body part 32 and the sealing part 31 provides elastic restoring force when the sealing part 31 is displaced, while preventing seal failure due to stress concentration. This embodiment is applicable to atomizing devices requiring frequent injection, achieving near-closed leak-proof performance of a liquid storage assembly while ensuring user operability.

[0031] Optionally, in this embodiment, the body portion 32 and the sealing portion 31 are integrally formed.

[0032] In this embodiment, the integrated design of the body part 32 and the sealing part 31 eliminates the assembly gap, further improving the sealing effect. Meanwhile, because the sealing part 31 needs to deform frequently (opening under pressure during liquid injection and closing upon rebound afterward), the split structure is prone to stress concentration at the connection points, leading to cracks. Integrated molding avoids these problems and has the beneficial effect of improving the service life of the seal 30.

[0033] Furthermore, the one-piece molding structure ensures that when the sealing part 31 deforms, the main body 32 acts as a stable base, which has the beneficial effect of avoiding the delay effect of the split structure.

[0034] Furthermore, the one-piece molded structure ensures consistent opening / closing stroke of the sealing part 31, eliminating the need for users to adjust the injection angle and thus improving the user experience.

[0035] Optionally, in this embodiment of the application, the blocking part 31 has a first end 311 and a second end 312, the first end 311 is connected to the body part 32, and the second end 312 extends in a direction away from the body part 32.

[0036] In this embodiment, the first end 311 is fixedly connected to the body part 32, providing structural support and ensuring that the sealing part 31 can elastically deform rather than detach under force. The second end 312 extends away from the body part 32, forming a free end, which can be designed as a conical, hemispherical, or flexible lip structure to fit against the inner wall of the injection hole 111 to achieve a seal. In its natural state, the second end 312 tightly fits against the inner wall of the injection hole 111, forming a seal to prevent leakage or external contamination. When the injection needle (or external pressing tool) applies force from outside the atomizer: the force acts on the second end 312, causing it to elastically deform (such as compress, bend, or fold) away from the injection hole 111. The deformation causes the second end 312 to separate from the inner wall of the injection hole 111, forming a channel for liquid injection. When the injection needle is pulled out or the external force disappears, the sealing part 31 returns to its original shape due to the elasticity of the material, and the second end 312 automatically seals again against the injection hole.

[0037] Optionally, in this embodiment of the application, the size of the sealing part 31 gradually decreases along the first direction X from the first end 311 to the second end 312; wherein, the first direction X is the axial direction of the injection hole 111.

[0038] In this embodiment, a uniform stress distribution is achieved through a gradual thickness design. Specifically, the thickness of the sealing part 31 gradually decreases from the first end 311 to the second end 312. In practical applications, the first end 311 is the location where the sealing part 31 is frequently deformed, and frequent deformation can easily lead to cracks. The aforementioned thickening of the first end 311 has the beneficial effect of avoiding repeated deformation that could cause the first end 311 to break and separate from the main body 31, thereby improving the service life of the sealing part 31.

[0039] Optionally, in this embodiment of the application, the size of the sealing part 31 gradually decreases along the second direction Y from the first end 311 to the second end 312; wherein, the second direction Y is the radial direction of the injection hole 111.

[0040] In this embodiment, the radial dimension of the sealing portion 31 decreases from the first end 311 to the second end 312 (free end), forming a truncated cone structure. This design causes the sealing contact pressure to decrease exponentially from the first end 311 to the second end 312, enabling low-pressure opening. Specifically, the second end 312 preferentially detaches from the wall of the injection hole 111, requiring only a small amount of hydraulic pressure for initial opening. It also enables step-like closure; at the moment the injection ends, the high elasticity of the first end 311 drives the sealing element 30 to sequentially adhere from the end to the root, effectively improving the closing speed and preventing leakage of the atomized matrix.

[0041] Optionally, in this embodiment, the side of the sealing part 31 near the injection hole 111 is fitted with the inner wall surface of the housing assembly 10.

[0042] In this embodiment, the arrangement of the side of the sealing part 31 near the injection hole 111 fitting the inner wall surface of the housing assembly 10 can achieve precise surface matching when the sealing part 31 seals the injection hole 111, thus achieving adaptive sealing and improving the sealing effect.

[0043] Furthermore, the smooth connection between the sealing part 31 and the body part 32 near the injection hole 111, which fits into the housing assembly 10, plays a crucial role in the liquid injection and sealing process of the atomizer. The smooth connection surface effectively reduces the resistance to the flow of the atomizing matrix, allowing it to flow more smoothly through the injection hole 111 into the receiving cavity 40 during injection, reducing the retention of the atomizing matrix at the sealing part 31. After injection, the sealing part 31 returns to its original shape and reseals the injection hole 111. Because the smooth surface lacks grooves, gaps, or other structures, it minimizes the risk of dead zones caused by residual medication. Once the residual medication dries and hardens, it may compromise the sealing fit between the sealing part 31 and the injection hole 111, leading to seal failure. The smooth connection design effectively avoids this risk, continuously ensuring the reliability of the sealing structure.

[0044] Furthermore, this smooth connection facilitates cleaning and maintenance, reducing the risk of bacterial growth and hygiene issues caused by residual atomizing matrix during long-term atomizer use. From a product quality perspective, it helps improve the overall quality and lifespan of the product, avoids product malfunctions and user complaints due to seal failure, enhances the product's competitiveness in the market, and provides users with a more stable, hygienic, and reliable user experience.

[0045] Furthermore, the side of the sealing part 31 facing away from the injection hole 111 is an arc surface. The arc surface structure can evenly distribute the external injection pressure to the entire sealing part 31, avoiding deformation and failure of the sealing part 31 caused by local stress concentration. During injection, the pressure is transmitted to the edge of the sealing part 31 along the tangential direction through the arc surface, making it deform more smoothly away from the injection hole 111, thus achieving smooth unsealing of the injection hole 111; after the injection is completed, the arc surface, with its curved elastic potential energy, causes the sealing part 31 to quickly and evenly reset, tightly fitting the edge of the injection hole 111.

[0046] Optionally, in this embodiment of the application, the injection hole 111 is an elongated hole, and the dimension of the injection hole 111 along the third direction Z is greater than the dimension of the injection hole 111 along the second direction Y.

[0047] In this embodiment, the third direction Z is the longitudinal direction of the atomizer. Compared to round orifices, elongated orifices provide a larger cross-sectional area under the same orifice diameter constraints, accelerating the flow rate of the atomizing matrix and reducing injection time. This is particularly suitable for high-viscosity liquids, reducing flow resistance. Simultaneously, the structure of elongated orifices is less likely to be completely blocked by air bubbles, facilitating continuous inflow of the atomizing matrix. Rapid air bubble removal reduces the risk of "dry burning" during atomization (liquid failing to wet the heating element in time). Arranging elongated orifices along the third direction Z guides the atomizing matrix to more evenly wet the atomizing core (such as ceramic or cotton cores), avoiding localized drying or oversaturation. With the trend towards miniaturization in atomizer development, elongated orifices can more flexibly adapt to the internal layout of the atomizer, avoiding interference with components such as electrodes and seals.

[0048] It should be noted that the elongated hole can be an elliptical hole, a strip-shaped hole, or a rectangular hole. This embodiment does not impose any limitations on this and can be determined according to the actual situation.

[0049] Optionally, in this embodiment of the application, the housing includes an outer shell 11 and an injection plug 12, with an injection hole 111 formed in the outer shell 11 and the injection plug 12 detachably connected to the injection hole 111.

[0050] In this embodiment, the injection plug 12 is used to seal the injection hole 111. In practical applications, the injection plug 12 is generally inserted into the injection hole 111 to seal the outer shell 11. When it is necessary to inject liquid into the atomizer, the injection plug 12 and the injection hole 111 are separated, the injection bottle is inserted through the injection hole 111 and pushes open the sealing part 31 to inject liquid into the atomizer. After the injection bottle leaves the injection hole 111, the sealing part 31 returns to its original fit against the inner wall of the outer shell 11, preventing the atomizing matrix inside the atomizer from flowing out.

[0051] Secondly, in this application embodiment, an atomizing device is also provided, including: an atomizer as described above; a power supply component; the power supply component and the atomizer are electrically connected to provide a working voltage for the atomizer.

[0052] In this embodiment, the atomizing device includes a power supply component and an atomizer, with the atomizer connected to one end of the power supply component. Specifically, the structure of the atomizer can be referred to in the above embodiments. The power supply component also includes a power source, such as a battery, which is configured to supply power to the atomizer to enable the atomizing device to function. Since the atomizing device adopts all the technical solutions of all the above embodiments of the atomizer, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated further here.

[0053] Furthermore, the atomizer may contain an atomizing airflow channel, and the atomizer is connected to one end of the housing assembly 10 of the power supply component. Specifically, the atomizer can be detachably connected to one end of the power supply component, or it can be integrated with the power supply component. By detachably connecting the atomizer to the power supply component, users can easily replace the atomizer according to their needs, which can extend the lifespan of the electronic atomizing device and improve the user experience.

[0054] Furthermore, the atomizing device in this application can be applied to various atomization scenarios. For example, it can be used in medical aesthetics, nicotine delivery, and daily life atomization scenarios. The aerosol atomization matrix can be pharmaceutical powder, fragrance, nicotine preparations, or aerosol matrices that can produce special odors.
