Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to an electronic atomizer. Background Technology

[0002] In some open-oil e-cigarettes, the atomizer includes a reservoir and an atomizing component housed within it. The atomizing medium in the reservoir flows directly into the inlet of the atomizing component. Compared to a method where the medium is introduced into the inlet via a guiding medium, this direct inflow of the atomizing medium makes the atomizing component more prone to oversaturation, leading to increased leakage. Therefore, to reduce leakage, some open-oil e-cigarettes incorporate a sealing component at the inlet. By moving this sealing component, the opening and closing of the inlet is controlled, thereby minimizing leakage.

[0003] However, because electronic atomizer users are located all over the world, there are significant differences in ambient temperature across different countries and regions. Looking at the atomizing matrix itself, its main component, propylene glycol, has a volume expansion coefficient of approximately 0.0006 / ℃, while glycerin reaches 0.0005 / ℃. When the ambient temperature fluctuates by 30℃—for example, from -10℃ in frigid regions to 20℃ in tropical regions—the volume of the matrix in a 10ml reservoir may change by 0.15 to 0.18ml. For reservoirs with a volume typically ranging from 2 to 50ml, this volume change is sufficient to cause significant internal pressure fluctuations.

[0004] The rigid structure of the liquid storage tank further amplifies the impact of pressure. When the temperature rises sharply, the substrate expands rapidly while the tank body remains almost unchanged, causing the internal pressure to surge instantly. At this time, the sealing connection between the sealing component and the inlet port, due to its tight fit (usually using an interference fit), will be further compressed by the expanding liquid. The silicone sealing component may be squeezed into the fine grooves of the inlet port, forming a temporary reinforced seal, which in turn prevents the liquid from overflowing from the inlet port.

[0005] However, the sealing system of an electronic atomizer is not a single, integrated unit. Potential gaps exist at the joint between the liquid reservoir and the atomizer base, the gaps where the electrodes penetrate the reservoir, and even the edge of the silicone plug at the filling port. The sealing of these parts often relies on static sealing rings or pressure-fitting structures. For example, the connection between the base and the reservoir may only be sealed with an O-ring. When the pressure inside the reservoir increases, liquid molecules can seep through the tiny gaps between the O-ring and the reservoir wall. Especially when the O-ring shows slight aging due to long-term use, or when there is a micron-level misalignment during assembly, the gaps can become a breakthrough point for pressure release.

[0006] More complex is the "fatigue effect" caused by temperature cycling. When equipment expands and leaks under high temperature conditions, if it is transferred to a low temperature environment, the shrinkage of the substrate will create negative pressure inside the chamber. At this time, external air may seep in through the same gap, carrying moisture or impurities into the chamber. When the temperature is raised again, the seeping air and the expanding substrate work together to cause more drastic fluctuations in internal pressure. The originally tiny gaps gradually widen under repeated compression and suction, eventually causing leakage to become a regular occurrence instead of an occasional phenomenon. Utility Model Content

[0007] The main objective of this application is to provide an electronic atomizer that solves the technical problem of leakage caused by changes in ambient temperature.

[0008] To achieve the above objectives, this application proposes an electronic atomizer, the electronic atomizer comprising: Rigid liquid storage chamber, with the chamber wall made of rigid material; An elastic liquid storage cavity is connected to the rigid liquid storage cavity, and the cavity wall of the elastic liquid storage cavity is made of an elastic material; An atomizing component is disposed within the rigid liquid storage chamber, and the atomizing component has a liquid inlet; and A sealing assembly is disposed within the rigid liquid storage cavity and located at the liquid inlet. The sealing assembly is movable toward the liquid inlet to close the liquid inlet and movable away from the liquid inlet to open the liquid inlet.

[0009] Optionally, the volume of the elastic reservoir is less than or equal to 0.1 ml before the electronic atomizer is used for the first time.

[0010] Optionally, the volume ratio of the rigid liquid storage chamber to the elastic liquid storage chamber is 50:1 to 80:1.

[0011] Optionally, the electronic atomizer includes: The outer casing assembly forms the rigid liquid storage cavity; An elastic bladder forms the elastic fluid reservoir; and A connecting pipe is connected at both ends to and in communication with the rigid liquid storage chamber and the elastic liquid storage chamber, respectively.

[0012] Optionally, the wall thickness of the elastic bladder is 0.3~0.5mm, and the cavity wall of the elastic bladder has an elastic deformation capacity of 30~50%.

[0013] Optionally, the inner diameter of the connecting pipe is 2~3mm.

[0014] Optionally, the outer wall of the outer shell assembly is recessed inward to form a clearance groove, the elastic bladder and the connecting tube are disposed in the clearance groove, and the end of the connecting tube away from the elastic bladder is connected to the outer shell assembly.

[0015] Optionally, the clearance groove is formed on the bottom outer wall of the housing assembly.

[0016] Optionally, the elastic bladder, after expansion, takes a cylindrical shape.

[0017] Optionally, the elastic capsule is made of materials such as natural latex, synthetic rubber, and / or silicone.

[0018] Optionally, the sealing assembly includes a sealing member and an elastic member. The sealing member faces the liquid inlet, and the two ends of the elastic member are respectively connected to the cavity wall of the rigid liquid storage chamber and the sealing member. The elastic member is in a compressed state and is used to drive the sealing member to move toward the liquid inlet to close the liquid inlet. The electronic atomizer includes: A driving component is used to drive the sealing component to move away from the inlet hole to open the inlet hole.

[0019] In this electronic atomizer, the combined structure of a rigid and an elastic reservoir effectively addresses the leakage problem caused by environmental temperature differences at the source of pressure regulation. The rigid reservoir, as the primary reservoir space, retains the advantages of a rigid structure in resisting external forces and connecting the atomizing and sealing components. The elastic reservoir's walls are elastic; when the ambient temperature rises, the atomizing matrix expands, and the elastic reservoir expands accordingly, absorbing excess atomizing matrix from the rigid reservoir. When the ambient temperature drops, the atomizing matrix contracts, and the elastic reservoir automatically contracts due to the decrease in internal pressure, pushing the remaining atomizing matrix back into the rigid reservoir, preventing negative pressure from forming in the rigid reservoir. Therefore, this electronic atomizer is less prone to leakage in a wide temperature range, significantly improving its adaptability to different climates. Attached Figure Description

[0026] This application discloses an electronic atomizer, comprising a rigid liquid reservoir, an elastic liquid reservoir, an atomizing component, and a sealing component. The rigid liquid reservoir has a wall made of a rigid material. An elastic liquid reservoir is connected to the rigid liquid reservoir, and its wall is also made of an elastic material. The atomizing component is disposed within the rigid liquid reservoir and has an inlet port. The sealing component is disposed within the rigid liquid reservoir and located at the inlet port; the sealing component is movable toward the inlet port to close it and movable away from it to open it.

[0027] In this electronic atomizer, the combined structure of a rigid and an elastic reservoir effectively addresses the leakage problem caused by environmental temperature differences at the source of pressure regulation. The rigid reservoir, as the primary reservoir space, retains the advantages of a rigid structure in resisting external forces and connecting the atomizing and sealing components. The elastic reservoir's walls are elastic; when the ambient temperature rises, the atomizing matrix expands, and the elastic reservoir expands accordingly, absorbing excess atomizing matrix from the rigid reservoir. When the ambient temperature drops, the atomizing matrix contracts, and the elastic reservoir automatically contracts due to the decrease in internal pressure, pushing the remaining atomizing matrix back into the rigid reservoir, preventing negative pressure from forming in the rigid reservoir. Therefore, this electronic atomizer is less prone to leakage in a wide temperature range, significantly improving its adaptability to different climates.

[0028] Please see Figures 1 to 5 The following will mainly describe the specific structure of the electronic atomizer 100.

[0029] The electronic atomizer 100 of this application includes a housing assembly 110, which forms a rigid liquid reservoir 113. The wall of the rigid liquid reservoir 113, i.e., the housing assembly 110, is made of a rigid material (such as plastic or glass). The rigid liquid reservoir 113 is used to store the atomizing matrix. The housing assembly 110 includes an upper shell 111 and a mounting base 112, with the mounting base 112 inserted into the bottom end of the upper shell 111.

[0030] The electronic atomizer 100 of this application includes an elastic capsule 140, which forms an elastic liquid reservoir 141. The elastic liquid reservoir 141 is connected to a rigid liquid reservoir 113, and the wall of the elastic liquid reservoir 141, i.e., the elastic capsule 140, is made of an elastic material. The elastic capsule 140 can be made of materials such as natural latex, synthetic rubber, and / or silicone. All of the above materials are food-grade.

[0031] The electronic atomizer 100 of this application includes a connecting tube 150, the two ends of which are respectively connected to and communicate with a rigid liquid storage chamber 113 and an elastic liquid storage chamber 141. The inner diameter of the connecting tube 150 is 2~3mm, thereby adapting the inner diameter of the connecting tube 150 to the expansion characteristics of the atomizing matrix.

[0032] Specifically, considering the expansion requirements of the atomized matrix, when fluctuations in ambient temperature cause volume changes, the flow transfer between the rigid reservoir 113 and the elastic reservoir 141, or vice versa, needs to be completed quickly through the connecting tube 150. Taking the expansion of 0.15-0.18 ml of 10 ml matrix at a 30°C temperature difference as an example, this volume change needs to be completed within a short time (typically, the response window for temperature changes is 1-2 minutes). If the connecting tube 150 is too thin, for example, with a diameter of only 1 mm, its cross-sectional area is only about 0.785 mm², limiting the flow rate per unit time. Based on the matrix viscosity (the viscosity of a propylene glycol and glycerol mixture at room temperature is approximately 15-20),... Calculations show that it takes about 30 seconds for 0.15ml of matrix to completely flow into the elastic reservoir, which may cause the pressure in the rigid reservoir 113 to temporarily exceed the limit. However, the cross-sectional area of ​​the 2mm diameter connecting tube 150 is 3.14mm², and that of the 3mm diameter tube is about 7.07mm², which corresponds to a flow rate that can be increased by 3 to 8 times. 0.18ml of matrix can be transferred in only 3 to 8 seconds, which can respond in real time to the pressure changes caused by matrix expansion and avoid pressure accumulation.

[0033] This inner diameter also balances the resistance and efficiency of matrix flow. Although the atomized matrix has good flowability, its viscosity increases slightly at low temperatures (it may increase to 30-40 at -10℃). If the inner diameter is less than 2 mm, the flow resistance will increase quadratically as the inner diameter decreases (according to Poiseuille's law, the resistance is inversely proportional to the fourth power of the inner diameter). This may result in slow matrix flow. For example, when the matrix shrinks at low temperatures, the elastic reservoir 141 needs to push the matrix back to the rigid reservoir 113. If the pipeline is too thin, the return flow will be slow, and the rigid reservoir 113 is prone to forming a temporary negative pressure. However, when the inner diameter is 2-3 mm, even if the viscosity increases at low temperatures, the flow resistance can still be controlled within 0.005 MPa. The contraction force of the elastic reservoir 141 is sufficient to easily push the matrix back, ensuring smooth bidirectional flow.

[0034] If the inner diameter of the connecting tube 150 deviates from this range, it may trigger a chain of problems. An excessively large inner diameter can lead to space constraints, as the internal space for the connecting tube 150 within the electronic atomizer 100 is limited (typically only a 5-8mm gap). An inner diameter of 4mm or more will compress the space available for the elastic bladder 140 or the rigid liquid reservoir 113. An excessively small inner diameter can easily cause localized blockages due to tiny impurities; once blocked, the pressure regulation system will directly fail. An inner diameter of 2-3mm avoids these potential problems while precisely matching the "small volume, fast response" expansion and flow requirements of the atomizing matrix, allowing the liquid flow effect and pressure regulation efficiency to be linked.

[0035] The electronic atomizer 100 of this application includes a sealing component 130, which is disposed in a rigid liquid storage chamber 113 and located at the liquid inlet 121. The sealing component 130 is capable of moving toward the liquid inlet 121 to close the liquid inlet 121 and moving away from the liquid inlet 121 to open the liquid inlet 121.

[0036] In the electronic atomizer 100 of this application, the combined structure of a rigid liquid storage chamber 113 and an elastic liquid storage chamber 141 solves the technical problem of leakage caused by environmental temperature differences from the source of pressure regulation. The rigid liquid storage chamber 113, as the main liquid storage space, retains the advantages of a rigid structure in resisting external forces and connecting the atomizing assembly 120 and the sealing assembly 130. The elastic liquid storage chamber 141 has elastic walls. When the ambient temperature rises, the atomizing matrix expands, and the chamber of the elastic liquid storage chamber 141 expands accordingly, absorbing excess atomizing matrix from the rigid liquid storage chamber 113. When the ambient temperature drops, the atomizing matrix contracts, and the elastic liquid storage chamber 141 automatically contracts due to the decrease in internal pressure, pushing the remaining atomizing matrix back into the rigid liquid storage chamber 113, preventing negative pressure from forming in the rigid liquid storage chamber 113. Therefore, the electronic atomizer 100 of this application is less prone to leakage in a wide temperature range, significantly improving its adaptability to different climate regions.

[0037] Before the electronic atomizer 100 is used for the first time, the volume of the elastic reservoir 141 is less than or equal to 0.1 ml. This volume refers to the volume of the elastic bladder 140 after it has been flattened (in products made of materials with extremely high elastic deformation capacity, this volume can refer to the volume of the elastic bladder 140 before it expands). Ideally, the elastic bladder 140 is completely flattened, meaning the volume of the elastic reservoir 141 is 0. This setting of a volume less than or equal to 0.1 ml eliminates invalid space interference in the initial state, ensuring that the pressure regulation of the elastic reservoir 141 is precisely controllable from the first use. If the elastic reservoir 141 has a large volume when not in use, air will remain inside, and the volume compressibility of air is thousands of times that of liquid. After the initial injection, the air is trapped within the elastic reservoir 141. When the temperature changes, the air expands or contracts dramatically before the atomizing matrix, far exceeding the expansion of the atomizing matrix at the same temperature. This causes the elastic bladder 140 to prematurely expand due to the air, losing its buffering capacity against changes in the volume of the atomizing matrix. If the environment cools down, the air contraction will cause the elastic bladder 140 to prematurely contract, triggering negative pressure in the rigid reservoir 113, which may draw in external air and compromise the sealing stability. However, when the volume of the elastic reservoir 141 is ≤0.1ml, the residual air volume is ≤0.1ml, and its volume change due to temperature fluctuations can be controlled within 0.003ml, making its interference with overall pressure regulation negligible.

[0038] Meanwhile, the above settings are also to ensure the initial deformation margin of the elastic reservoir 141. Before the first use, the elastic bladder 140 needs to be in a naturally contracted, inactive state so that it can expand freely with the volume change of the atomizing matrix. If the initial volume of the elastic reservoir 141 is too large (more than 0.1 ml), the cavity wall of the elastic reservoir 141 may have slight stretching, which will cause the subsequent expandable deformation space to be compressed. When encountering extreme temperature differences (such as 50°C), it may not be able to support the expanding atomizing matrix due to insufficient deformation, resulting in the pressure of the rigid reservoir 113 exceeding the standard. When the initial volume of the elastic reservoir 141 is ≤0.1 ml, its cavity wall has almost no stretching, which can fully release the designed deformation capacity and ensure the buffering effect under extreme conditions.

[0039] Furthermore, the above settings are also related to the liquid filling efficiency during injection. The first injection of the electronic atomizer 100 typically involves injecting the atomizing matrix into the rigid reservoir 113. If the initial volume of the elastic reservoir 141 is large, some of the atomizing matrix will naturally flow into the elastic reservoir 141 during injection, making it difficult for the rigid reservoir 113 to fill quickly. Users would then need to refill multiple times to reach the nominal capacity, affecting the user experience. However, when the volume of the elastic reservoir 141 is ≤0.1ml, the amount of atomizing matrix flowing into the elastic reservoir 141 is negligible and has almost no impact on the filling volume of the rigid reservoir 113. This allows users to meet their needs with a single injection, while also avoiding initial pressure fluctuations caused by premature liquid buildup in the elastic reservoir 141.

[0040] The wall thickness of the elastic bladder 140 can be 0.3~0.5mm, and the cavity wall of the elastic bladder 140 can have an elastic deformation capacity of 30~50%. The above parameters are only based on conventional elastic materials, and this application is not limited to them. When the internal pressure increases, the elastic bladder 140 expands outward, up to a maximum of 1.5 times its original volume; when the pressure decreases, it contracts inward, with a minimum volume that can be compressed to 60% of its original volume. This deformation range precisely matches the volume change of the atomizing matrix under a temperature difference of ±40℃. Taking the combination of a 10ml rigid reservoir 113 and a 3ml elastic reservoir 141 as an example, when a 30℃ temperature difference causes a volume expansion of 0.15~0.18ml, the elastic reservoir 141 only needs to expand by 5%~6% of its original volume to accommodate the excess matrix, keeping the pressure inside the rigid reservoir 113 within a stable range of less than 0.02MPa, which is far below the critical pressure bearing value of the O-ring seal structure (usually 0.1MPa).

[0041] In some embodiments, the expanded elastic bladder 140 takes a cylindrical shape. This shape design ensures that the elastic bladder 140 maintains a controllable morphological characteristic during deformation. From a structural design perspective, the cylindrical shape of the elastic bladder 140 is well-suited to the elongated spatial layout inside the electronic atomizer 100. This avoids the irregular shape from encroaching on the installation space of core components such as the atomizing core and electrodes, and also reduces the difficulty of positioning during assembly due to the regular shape. The cylindrical shape also gives the elastic bladder 140 uniform deformation characteristics. Since the circumferential cavity wall of the cylindrical elastic bladder 140 experiences uniform stress, when the atomizing matrix expands and flows in due to temperature rise, the deformation of the elastic bladder 140 along the axial and radial directions will exhibit linear changes, avoiding the local bulging phenomenon that may occur with irregular shapes (such as spheres or ellipsoids). This uniform deformation allows the stretching of the cavity wall to be controlled within 20% at all points, effectively reducing the risk of aging and cracking of the cavity wall due to localized excessive stretching after long-term use, and further improving the fatigue resistance of the elastic bladder 140. Meanwhile, the fixed columnar shape also ensures the stability of pressure regulation. Compared to the irregularly shaped elastic bladder 140, the correspondence between volume changes and pressure changes in the columnar elastic bladder 140 is easier to control. By pre-calculating the volume data of the columnar elastic bladder 140 under different expansion amounts, its volume ratio with the rigid liquid storage chamber 113 can be accurately set. When the temperature changes, the predictable deformation of the columnar elastic bladder 140 can stably control the pressure fluctuations in the rigid liquid storage chamber 113 within the target range, making the pressure buffering function of the elastic bladder 140 more reliable, and thus more effectively preventing leakage.

[0042] In some embodiments, the volume ratio of the rigid fluid reservoir 113 to the elastic fluid reservoir 141 is 50:1 to 80:1. The volume of the elastic fluid reservoir 141 is the volume of the elastic bladder 140 when it has not undergone elastic deformation (basic volume). The above parameters are only based on conventional elastic materials and the volume of the rigid fluid reservoir 113, and this application is not limited thereto.

[0043] In terms of the actual expansion of the atomizing matrix, a volume ratio of 50:1 to 80:1 precisely covers the volume change requirements under normal temperature differences. The volume expansion rate of the atomizing matrix (a mixture of propylene glycol and glycerol) is usually stable at 0.0005 to 0.0006 / ℃. Even when encountering extreme temperature differences (such as -20℃ to 50℃, or a temperature difference of 70℃), the maximum expansion of 100ml of atomizing matrix is ​​only 0.35 to 0.42ml. At a ratio of 50:1, if the rigid reservoir 113 has a volume of 10ml (a common volume for electronic atomizers 100), then the basic volume of the elastic bladder 140 is 0.2ml. The elastic bladder 140 itself has a maximum expansion capacity of 1.5 times (i.e., an expanded volume of 0.3ml), which is sufficient to accommodate the expansion of 10ml of matrix under a temperature difference of 50℃ (0.25~0.3ml). At a ratio of 80:1, the basic volume of the elastic bladder 140 corresponding to the 10ml rigid reservoir 113 is 0.125ml, which expands to 0.1875ml. The elastic bladder 140 can also match the expansion under a normal temperature difference of 30℃ (0.15~0.18ml), which falls precisely in the daily usage scenarios of most users.

[0044] This ratio better highlights the design logic of "rigid liquid storage as the main component and elastic buffer as the secondary component". The core requirement of the electronic atomizer 100 is "battery life", that is, to reduce the frequency of users refilling liquid. Therefore, the rigid liquid storage chamber 113 needs to occupy the absolute dominant volume. With a ratio of 50:1 to 80:1, the basic volume of the elastic bladder 140 only accounts for 1.25% to 2% of the total liquid storage space, which hardly affects the liquid storage capacity of the whole device.

[0045] Furthermore, this also accommodates the miniaturized structural constraints of the electronic atomizer 100. Most devices have a body thickness of only 8-12mm, leaving limited installation space for the elastic bladder 140. If the basic volume of the elastic bladder 140 is too large (e.g., at a ratio of 20:1, a 10ml rigid reservoir 113 corresponds to a 0.5ml elastic reservoir 141, requiring a cylindrical space with a diameter of 8mm and a length of 10mm), it may encroach on the layout of the atomizer core and electrodes. However, at ratios of 50:1 to 80:1, the basic volume of the elastic bladder 140 is only 0.1-0.2ml, which can be easily embedded in the anti-cavity groove 114, forming a compact fit with the connecting tube (diameter 2-3mm) without affecting the overall size of the device.

[0046] In extreme scenarios, this ratio also has redundancy: if an unusual temperature difference (such as 70℃) is encountered, although the basic volume of the elastic bladder 140 is insufficient, the pressure of the rigid liquid storage chamber 113 will push it to deform to the limit (even slightly exceeding the design deformation rate by 10%). The short-term super-deformation of the silicone material (stretch rate ≤60%) will not cause permanent damage, and it can return to its original shape after cooling, which is reliable.

[0047] In the electronic atomizer 100 of this application, the outer wall of the outer shell assembly 110 is recessed inward to form a relief groove 114. The elastic bladder 140 and the connecting tube 150 are disposed in the relief groove 114, and the end of the connecting tube 150 away from the elastic bladder 140 is connected to the outer shell assembly 110. Thus, the outer shell assembly 110 can protect the elastic bladder 140. The relief groove 114 not only provides sufficient deformation space for the elastic bladder 140, but also limits the excessive outward expansion of the elastic bladder 140 through the inner side wall of the groove, so that the elastic bladder 140 always operates within the safe deformation range.

[0048] In some embodiments, the recess 114 is formed on the bottom outer wall of the housing assembly 110 (i.e., the bottom outer wall of the mounting base 112). Inside the body of the electronic atomizer 100, the middle section is typically occupied by a rigid liquid reservoir 113 and the atomizing coil, while the top requires space for a mouthpiece installation, leaving only the bottom mounting base 112 area relatively empty. The mounting base 112 itself needs to integrate basic structures such as electrodes and air intake channels, and its bottom outer wall is originally a flat or simple curved surface. Forming the recess 114 in this recess effectively utilizes the unused outer wall space of the mounting base 112, eliminating the need for additional accommodating cavities on the side or top of the body, thus avoiding an increase in the overall thickness or length of the device. This layout also allows for a more organized arrangement of internal components. Mounting base 112 is the basic support structure of the whole machine. The elastic bladder 140 and the connecting pipe 150 are attached to its bottom outer wall and can form a spatial relationship of upper and lower layers with the rigid liquid storage chamber 113, avoiding the cross stacking of components on the same plane. At the same time, from the assembly perspective, the clearance groove 114 on the bottom outer wall can be installed from the bottom of the equipment without disassembling the core components in the middle of the machine body, which can simplify the assembly process and reduce the probability of abnormal function of elastic bladder 140 due to assembly deviation.

[0049] In some embodiments, the sealing assembly 130 includes a sealing member 131 and an elastic member 132. The sealing member 131 faces the liquid inlet 121. The two ends of the elastic member 132 are respectively connected to the cavity wall of the rigid liquid storage chamber 113 and the sealing member 131. The elastic member 132 is in a compressed state and is used to drive the sealing member 131 to move toward the liquid inlet 121 to close the liquid inlet 121. The electronic atomizer 100 includes a driving member 160, which is used to drive the sealing member 131 away from the liquid inlet 121 to open the liquid inlet 121.

[0050] In the above embodiments, the sealing component 130 may include a magnet 133, and the driving element 160 may be an electromagnet. When the driving element 160 is energized, it can generate a magnetic force with the magnet 133. The magnetic force drives the sealing component 131 to move away from the liquid inlet 121 through the magnet 133. There may be two magnets 133. The polarities of the two magnets 133 facing the driving element 160 may be the same, that is, the two magnets 133 jointly drive the sealing component 131 to move away from the liquid inlet 121. The polarities of the two magnets 133 facing the driving element 160 may be different. The electronic control device (not shown) of the electronic atomizer 100 energizes the driving element 160 with current in different directions, so that one magnet 133 drives the sealing component 131 to move away from the liquid inlet 121, and the other magnet 133, together with the elastic element 132, jointly drives the sealing component 131 to move closer to the liquid inlet 121.

[0051] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
