Description

Technical Field

[0001] This invention relates to the field of atomization device technology, and particularly to an atomization chamber and atomization device. Background Technology

[0002] In the field of atomizing devices, leakage from the atomizing chamber has long been a critical technical challenge. The core cause lies in the pressure imbalance between the sealed chamber storing the atomizing liquid and the outside atmosphere. Changes in ambient temperature cause the air inside the chamber to expand; changes in altitude alter the pressure difference; atomizing liquid consumption increases the chamber's space, creating negative pressure; and tilting or shaking during use also affects the internal pressure. All these factors contribute to a pressure difference between the chamber and the outside atmosphere. This pressure difference directly affects the liquid atomizing liquid, causing it to leak from the atomizing components, nozzle, or the bottom of the chamber, severely impacting the user experience. Currently, the mainstream solution in the industry is a "completely sealed" approach. This solution attempts to prevent leakage by designing a completely sealed chamber structure, attempting to isolate the chamber from the outside atmosphere through structural tightness. However, this approach has significant drawbacks in practical applications. As the atomizing fluid is continuously consumed, a negative pressure gradually forms inside the chamber, leading to increased suction resistance for the user. In severe cases, it may even prevent the atomized aerosol from being drawn out properly. Furthermore, in scenarios with rising ambient temperatures or decreasing altitude, the residual air inside the chamber may expand due to heat or create positive pressure due to a decrease in external air pressure. This pressure forces the atomizing fluid to leak from the atomizing components, ultimately causing leakage and resulting in unstable leak-proof performance and low reliability. Therefore, achieving a balance between internal and external air pressure and reliable leak-proof performance has become a pressing technical challenge. Summary of the Invention

[0003] The embodiments of the present invention provide an atomizing chamber and an atomizing device, which solves the technical problem of leakage of atomizing liquid caused by the imbalance of air pressure inside and outside the chamber in the prior art.

[0004] To address the aforementioned problems, according to one aspect of this application, an embodiment of the present invention provides an atomizing chamber, the atomizing chamber comprising a chamber for containing atomizing liquid, a bottom cover, and a sealing element, the bottom cover being disposed at the bottom of the chamber, the sealing element being disposed at the top of the bottom cover, the bottom cover having a labyrinth groove, and the sealing element having a communicating groove, the labyrinth groove communicating with the communicating groove to form a pressure balance channel connecting the external atmosphere with the interior of the chamber.

[0005] In some embodiments, the labyrinth groove is a loop-type structure, which includes two laterally extending transverse grooves and a transition section connecting the two transverse grooves. The two transverse grooves are distributed in parallel, and the transition section connects the ends of the two transverse grooves.

[0006] In some embodiments, the labyrinth groove is formed on the side surface of the bottom cover facing the seal, and the seal fits against the bottom cover so that one end opening of the labyrinth groove aligns with one end opening of the connecting groove.

[0007] In some embodiments, there are two transition sections, which respectively connect the two ends of the two transverse grooves, and the extension direction of each transition section is perpendicular to the extension direction of the transverse groove. The two transverse grooves are symmetrically distributed laterally along the surface of the bottom cover, and together they enclose a closed loop.

[0008] In some embodiments, the seal is made of silicone, and the connecting groove is a through groove formed in the thickness direction of the seal. One end of the through groove is adapted to connect with the opening of the labyrinth groove, and the other end extends into the internal space of the compartment.

[0009] In some embodiments, the inner wall of the connecting groove is a smooth curved surface, which is used to reduce resistance during gas flow.

[0010] In some embodiments, the bottom cover is provided with a vent that extends through itself, and the vent is connected to the end of the labyrinth groove away from the connecting groove.

[0011] In some embodiments, the bottom cover is an injection-molded part, and the labyrinth groove is integrally injection-molded with the bottom cover; the sealing element, the bottom of the compartment, and the bottom cover are all interference fit.

[0012] In some embodiments, the side wall of the compartment is provided with oil-injecting silicone, which is embedded in the oil injection port of the compartment.

[0013] According to another aspect of this application, an embodiment of the present invention provides an atomizing device, including the aforementioned atomizing chamber, atomizing component, and electrode assembly. The atomizing component is disposed inside the lower part of the chamber; the electrode assembly is disposed below the bottom cover, and the electrode assembly includes an electrode base, an electrode pin, and electrode silicone. The electrode pin passes through the electrode base, and the electrode silicone is sleeved on the outside of the electrode pin; a magnet is also provided below the bottom cover, and the magnet is disposed adjacent to the electrode base.

[0014] Compared with the prior art, the atomizing chamber of the present invention has at least the following beneficial effects: The atomizing chamber provided by the present invention includes a chamber for containing atomizing liquid, a bottom cover, and a sealing element. The bottom cover is disposed at the bottom of the chamber, and the sealing element is disposed at the top of the bottom cover. The bottom cover is provided with a labyrinth groove, and the sealing element is provided with a connecting groove. The labyrinth groove and the connecting groove communicate with each other to form a pressure balance channel connecting the outside atmosphere and the interior of the chamber.

[0015] As the storage component for the atomizing liquid, the chamber is sealed at its bottom by a bottom cover and a sealing element, ensuring the airtightness of the atomizing liquid storage and preventing unexpected leakage. Simultaneously, the labyrinth groove on the bottom cover and the connecting groove on the sealing element form a pressure balance channel. This channel allows for gas exchange between the interior of the chamber and the outside atmosphere. Furthermore, when negative pressure forms inside the chamber due to atomizing liquid consumption, outside air enters through the channel formed by the labyrinth groove and the connecting groove, filling the space gap and balancing the negative pressure, thus avoiding increased suction resistance. When positive pressure forms inside the chamber due to increased temperature or decreased altitude, the expanding gas inside is discharged to the outside through this channel, releasing pressure and preventing the atomizing liquid from being squeezed. This method of achieving pressure balance through a dedicated gas channel not only overcomes the shortcomings of existing "completely sealed" technologies but also prevents atomizing liquid leakage through the sealing effect of the sealing element and the bottom cover, achieving a balance between internal and external pressure and reliable leak prevention, precisely solving the technical problems existing in traditional atomizing chambers.

[0016] The atomizing device provided by the present invention is designed based on the above-mentioned atomizing chamber. Its beneficial effects are the same as those of the atomizing chamber, and will not be repeated here.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0024] Example 1 This embodiment provides an atomizing chamber, such as Figures 1-5 As shown, the atomizing chamber includes a chamber 1 for containing atomizing liquid, a bottom cover 2, and a sealing element 3. The bottom cover 2 is placed on the bottom of the chamber 1, and the sealing element 3 is placed on the top of the bottom cover 2. The bottom cover 2 is provided with a labyrinth groove 21, and the sealing element 3 is provided with a connecting groove 31. The labyrinth groove 21 and the connecting groove 31 are connected to form a pressure balance channel connecting the outside atmosphere and the interior of the chamber 1.

[0025] The chamber 1, as the core component for containing the atomizing liquid, provides the basic installation space for the entire atomizing chamber. Its bottom mates with the bottom cover 2, sealing the bottom of chamber 1 and preventing the atomizing liquid from overflowing. Simultaneously, a labyrinth groove 21 is directly provided on the bottom cover 2. The labyrinth groove 21, as a key component of the air pressure balance channel, provides a specific path for gas flow. A sealing element 3 is fixedly installed at the bottom of chamber 1, i.e., the top of the bottom cover 2. The sealing element 3 serves two purposes: firstly, it seals the bottom of chamber 1 to prevent atomizing liquid leakage; secondly, it ensures a tight seal. The seal 3 has a connecting groove 31, which is connected to the labyrinth groove 21 on the bottom cover 2. More specifically, the seal 3 and the bottom cover 2 fit together so that one end of the connecting groove 31 is precisely connected to one end of the labyrinth groove 21, ensuring that the gas can pass smoothly through the continuous channel formed by the two. The chamber 1 forms a relatively closed storage space through the cooperation of the bottom cover 2 and the seal 3. The labyrinth groove 21 and the connecting groove 31 construct a dedicated gas passage in this closed space, which does not affect the storage of the atomizing liquid and can achieve communication with the outside atmosphere.

[0026] Because the sealing element 3 and the bottom cover 2 fit together, the labyrinth groove 21 and the connecting groove 31 form an uninterrupted channel. One end of this channel leads to the outside atmosphere, and the other end extends directly into the interior of the compartment 1. When the air pressure inside the compartment 1 changes due to various factors, the gas can enter the connecting groove 31 along the labyrinth groove 21, and then enter the interior of the compartment 1 from the connecting groove 31, or flow from the interior of the compartment 1 through the connecting groove 31 to the labyrinth groove 21, and finally be discharged to the outside. While ensuring the sealing performance of the compartment 1, the bottom cover 2 and the sealing element 3 provide a dedicated path for gas circulation through the groove structure on them, realizing the coordinated work of sealed storage and gas circulation.

[0027] The problem with existing technologies is leakage of the atomizing liquid caused by the pressure imbalance between the sealed chamber and the outside atmosphere. This embodiment solves this problem fundamentally through the ingenious combination of chamber 1, bottom cover 2, sealing element 3, labyrinth groove 21, and connecting groove 31. Chamber 1, as the atomizing liquid storage component, has its bottom sealed by the bottom cover 2 and sealing element 3, ensuring the airtightness of the atomizing liquid storage and preventing unexpected leakage. Simultaneously, the labyrinth groove 21 on the bottom cover 2 and the connecting groove 31 on the sealing element 3 form a pressure balance channel, allowing gas exchange between the interior of chamber 1 and the outside atmosphere. Furthermore, when a negative pressure forms inside chamber 1 due to atomizing liquid consumption... At this time, the outside atmosphere enters the interior of chamber 1 through the channel formed by the labyrinth groove 21 and the connecting groove 31, filling the space gap to balance the negative pressure and avoiding the problem of increased suction resistance. When positive pressure is formed in chamber 1 due to temperature rise or altitude decrease, the internal expanding gas will be discharged to the outside through the channel in the opposite direction to release pressure and avoid squeezing the atomizing liquid. This method of achieving air pressure balance through a dedicated gas channel not only eliminates the defects of the existing technology of "complete sealing", but also prevents the atomizing liquid from leaking through the sealing effect of the sealing element 3 and the bottom cover 2. It achieves the unity of air pressure balance inside and outside the chamber and reliable liquid prevention, and accurately solves the technical problems existing in traditional atomizing chambers.

[0028] In addition, in a specific embodiment, four annular elastic protrusions are integrally formed on the side surface of the sealing member 3 facing the bottom cover 2 at the opening edge of the connecting groove 31. The height of the elastic protrusions is 0.2mm higher than the contact surface between the sealing member 3 and the bottom cover 2. Correspondingly, the labyrinth groove 21 has an annular shallow groove adapted to the elastic protrusions at the opening edge of the sealing member 3, and the depth of the shallow groove is 0.15mm. When the air pressure inside and outside the chamber 1 is stable, the elastic protrusions naturally fit into the shallow grooves, without affecting the smooth flow of gas between the labyrinth groove 21 and the connecting groove 31. When the pressure inside the chamber 1 changes suddenly due to violent shaking or a sudden change in altitude, the air pressure will push the sealing member 3 slightly towards the bottom cover 2, causing the elastic protrusions to be further embedded into the shallow grooves. By deforming, the gap between the two is reduced, forming a dynamically enhanced seal, preventing the atomized liquid from leaking from the joint under pressure impact. This adaptive sealing structure design links the sealing effect with changes in air pressure, ensuring air pressure balance efficiency under normal conditions and solving the sealing failure problem under extreme conditions, further improving the reliability of the atomizing chamber. At the same time, the elastic protrusion and the sealing element 3 are integrally molded, and the shallow groove and the labyrinth groove 21 are integrally injection molded, eliminating the need for additional assembly processes and ensuring compatibility with existing production processes.

[0029] In a specific embodiment, the maze groove 21 is a loop-type structure, which includes two horizontally extending transverse grooves 211 and a transition section 212 connecting the two transverse grooves 211. The two transverse grooves 211 are distributed in parallel, and the transition section 212 connects the ends of the two transverse grooves 211.

[0030] The loop-type structure of the labyrinth groove 21 is a key design for achieving leak prevention and air pressure balance. The two transverse grooves 211 extend laterally along the surface of the bottom cover 2 and are distributed in parallel with a uniform spacing. This distribution allows the gas to form a stable flow trajectory when flowing in the groove, and there will be no local airflow congestion. More specifically, the transition section 212 is connected to the same end of the two transverse grooves 211, and its two ends are seamlessly connected to the ends of the two transverse grooves 211, connecting the two originally independent transverse channels into a complete closed loop. This makes the overall path of the labyrinth groove 21 no longer a simple straight line, but a winding and turning structure.

[0031] The beneficial effects of this embodiment are significant. First, the loop structure greatly extends the actual path length of gas flow. At the same time, the tortuous path shape naturally obstructs the liquid atomizing liquid. The liquid atomizing liquid itself has a certain viscosity and volume, and it will encounter greater resistance when trying to pass through the turning path, making it difficult to flow forward smoothly. However, gas molecules are small in size and highly fluid, and can easily pass through these turning parts, thus achieving the core effect of "gas passing through but oil not". This ensures the gas exchange required for pressure balance and effectively prevents the atomizing liquid from leaking through the labyrinth groove 21. Furthermore, the two parallel transverse grooves 211 can provide bidirectional gas flow channels, making the gas flow in the groove smoother and avoiding the airflow obstruction problem that may occur with a single channel. The stable connection of the transition section 212 ensures the integrity and stability of the loop structure, making the labyrinth groove 21 less prone to damage or deformation during production assembly and long-term use. This improves the leak-proof reliability and structural durability of the entire atomizing chamber. At the same time, this structural design is simple, requiring no additional complex processing steps and not significantly increasing the production difficulty, which meets the need for simplified processes.

[0032] In a specific embodiment, the labyrinth groove 21 is formed on the side surface of the bottom cover 2 facing the sealing member 3, and the sealing member 3 is fitted to the bottom cover 2, so that one end opening of the labyrinth groove 21 is connected to one end opening of the connecting groove 31.

[0033] The labyrinth groove 21 is located on the surface of the bottom cover 2 facing the seal 3. This design allows the labyrinth groove 21 to directly engage with the seal 3. More specifically, the surface of the bottom cover 2 facing the seal 3 is flattened to ensure full and tight contact when the seal 3 is in place, leaving no gaps. The labyrinth groove 21 is formed in a recessed form on this flat surface, ensuring its own structural integrity without compromising the bonding foundation between the bottom cover 2 and the seal 3. When the seal 3 is in contact with the bottom cover 2, it is not a simple surface contact, but a tight fit achieved through its own structural adaptation. This fit provides lateral closure to the labyrinth groove 21, preventing gas or atomized liquid from leaking out of the side gaps of the labyrinth groove 21. Furthermore, it aligns one end of the labyrinth groove 21 with one end of the connecting groove 31 on the seal 3, achieving a seamless connection. This allows gas to flow directly from the labyrinth groove 21 into the connecting groove 31 without the need for an additional transition structure.

[0034] In this embodiment, the tight fit and precise docking ensure the air pressure balance channel's sealing performance. This prevents gas leakage from the mating surface during flow, thus avoiding impact on the efficiency of air pressure balance, and also prevents the atomizing liquid from seeping into the labyrinth groove 21 through gaps, improving leak-proof reliability. This direct docking method simplifies the gas flow path, reduces obstruction during gas flow, and allows the air pressure inside and outside the chamber 1 to quickly reach equilibrium, effectively addressing air pressure changes caused by various factors. At the same time, the labyrinth groove 21 is hidden between the mating surfaces of the bottom cover 2 and the sealing element 3, and is not exposed to the external environment. This prevents external impurities from entering the labyrinth groove 21 and causing blockage, and also makes the overall external structure of the atomizing chamber simpler, eliminating the need for additional protective components. Furthermore, this design does not require complex positioning or connection structures; during assembly, simply aligning and fitting the sealing element 3 with the bottom cover 2 is sufficient to complete the channel docking, reducing assembly difficulty.

[0035] In a specific embodiment, there are two transition sections 212, which respectively connect the two ends of the two transverse grooves 211. The extension direction of each transition section 212 is perpendicular to the extension direction of the transverse groove 211. The two transverse grooves 211 are symmetrically distributed laterally along the surface of the bottom cover 2, and together they enclose a closed loop.

[0036] Two transverse grooves 211 are arranged symmetrically along the transverse direction of the bottom cover 2, maintaining a uniform and fixed distance from each other. This symmetrical distribution enables the positions of the two transverse grooves 211 to be accurately corresponding, laying a stable foundation for the subsequent connection with the transition section 212. The number of the transition sections 212 is set to two, and these two transition sections 212 are respectively connected to the two ends of the two transverse grooves 211. One end of each transition section 212 is tightly docked with the end of one of the transverse grooves 211, and the other end is seamlessly fitted with the corresponding end of the other transverse groove 211. At the same time, the extending direction of each transition section 212 is perpendicular to the transverse extending direction of the transverse groove 211, enabling the transition section 212 and the two transverse grooves 211 to jointly enclose a complete and regular closed loop, making the path of the labyrinth groove 21 present a clear "return" - shaped structure.

[0037] The two symmetrically distributed transverse grooves 211 and the two perpendicularly - connected transition sections 212 further extend the path length of the closed loop and make the angles at the turning points more regular, which can form multiple barriers to the liquid atomized liquid. The atomized liquid needs to change its direction multiple times during the flow process to pass through, and its own viscosity and volume will make these turns become difficult - to - cross obstacles. On the contrary, the gas can easily pass through, thus more efficiently achieving the effect of "allowing gas to pass through but not liquid", greatly enhancing the leak - proof reliability; furthermore, this symmetric and closed structure makes the force on the labyrinth groove 21 on the bottom cover 2 more uniform, and it is not easy to deform or have uneven wall thickness during the injection molding process, improving the structural stability and production qualification rate of the bottom cover 2. At the same time, the two transition sections 212 are respectively connected to the two ends of the transverse groove 211, enabling the gas to have the possibility of two - way circulation in the loop, avoiding the problem of air flow blockage that may occur in single - direction circulation, and ensuring that the air pressure inside and outside the chamber 1 can quickly respond and reach equilibrium; in addition, this structural design does not require additional complex processing steps. When the bottom cover 2 is fitted with the seal 3, the opening of the closed loop can also be more accurately docked with the communication groove 31, without affecting the assembly accuracy due to complex structure.

[0038] In addition, the loop structure of the labyrinth groove 21 further includes two branch grooves, which respectively extend from the same side of the transverse groove 211, and the ends of the two branch grooves converge in the upper region of the bottom cover 2.

[0039] In a specific embodiment, the seal 3 is made of silica gel material, the communication groove 31 is a through - groove opened in the thickness direction of the seal 3, one end of the through - groove is adaptively docked with the opening of the labyrinth groove 21, and the other end extends into the internal space of the chamber 1.

[0040] The seal 3 is made of silicone, which has good softness and elasticity, and can better adapt to the surface shape of the bottom cover 2. It will not affect the fit due to the slight unevenness of the bottom cover 2 surface. The connecting groove 31 is formed through the thickness of the seal 3, extending from the side of the seal 3 facing the bottom cover 2 to the side facing the compartment 1, forming a complete through channel. The opening size and shape of the connecting groove 31 are perfectly matched with the opening of the labyrinth groove 21, achieving precise fitting and connection, so that there will be no gaps or misalignment when the two are connected. The other end of the connecting groove 31 extends directly into the internal space of the compartment 1, achieving connection with the interior of the compartment 1 without the need for other transfer structures. In this embodiment, the softness and elasticity of the silicone material allow the seal 3 to undergo slight compression deformation when it is fitted to the bottom cover 2, tightly filling the tiny gap between them. This not only enhances the overall sealing performance but also makes the connection between the connecting groove 31 and the labyrinth groove 21 more secure, preventing gas leakage from the connection point and effectively blocking the atomizing liquid from seeping into the connection gap. Furthermore, the through groove opened along the thickness direction makes the gas flow path more direct, eliminating the need for detours and reducing obstruction during gas flow. This allows the pressure changes inside and outside the chamber 1 to be quickly transmitted and balanced through the channel, while the matching connection design avoids airflow obstruction or local stagnation caused by mismatched openings. In addition, silicone material itself is easy to process, and the process of opening the through groove is simple, which does not significantly increase production costs. Moreover, silicone has a certain degree of corrosion resistance and will not deteriorate or be damaged after contact with the atomizing liquid, ensuring long-term reliability. At the same time, this structural design does not require additional sealing gaskets or connecting parts, simplifying the overall structure.

[0041] In a specific embodiment, the inner wall of the connecting groove 31 is a smooth curved surface, which is used to reduce the resistance during gas flow.

[0042] The inner wall of the connecting channel 31 is a smooth curved surface without any sharp edges or corners, with a natural and smooth transition. From the opening at one end of the connecting channel 31 that connects to the labyrinth channel 21, it extends to the other end leading to the interior of the chamber 1. The entire inner wall has no uneven textures or sudden turns, allowing gas to move along a smooth path as it flows. More specifically, this smooth curved surface design is perfectly suited to the needs of gas flow. When gas enters the connecting channel 31 from the labyrinth channel 21, it will not be obstructed by the protrusions or sharp corners of the inner wall, nor will it form local airflow vortices or stagnant areas. Instead, it can flow smoothly along the curved surface into the interior of the chamber 1. Conversely, the gas in the chamber 1 can also have the same smooth flow experience when it is discharged. This embodiment effectively reduces the resistance to gas flow, allowing pressure changes inside and outside chamber 1 to be quickly transmitted through the channel. Whether it is the entry of outside air when the atomizing liquid is consumed and negative pressure is formed, or the expulsion of internal gas when the temperature rises or altitude changes and positive pressure is formed, it can be completed more promptly, avoiding the situation where pressure balance is delayed due to excessive resistance, which could lead to atomizing liquid leakage. In addition, the smooth inner wall is not easy for atomizing liquid residue to adhere to. Liquid atomizing liquid itself has a certain viscosity. If the inner wall has rough textures or edges, it is easy to be absorbed and gradually accumulate. Long-term use may lead to narrowing or even blockage of the channel. However, the smooth curved surface makes it difficult for atomizing liquid to adhere. Even if a small amount of atomizing liquid comes into contact with the inner wall, it will flow back into the chamber 1 along the curved surface, ensuring the smoothness of the connecting channel 31 for long-term use.

[0043] In a specific embodiment, the bottom cover 2 is provided with a vent 22 that penetrates through it, and the vent 22 is connected to the end of the labyrinth groove 21 away from the connecting groove 31.

[0044] A vent 22 is located on the bottom cover 2 and extends through the entire thickness of the bottom cover 2, from the outer surface of the bottom cover 2 away from the seal 3 to the inner surface facing the seal 3, forming an independent channel that is open to both the inside and outside. The inner port of the vent 22 is aligned with the end of the labyrinth groove 21 away from the connecting groove 31, and the two fit together seamlessly at the joint, without gaps or misalignment. This allows outside air to directly enter the labyrinth groove 21 through the vent 22, while the gas inside the labyrinth groove 21 can also be discharged to the outside through the vent 22 along the same path, forming a dedicated port for the air pressure balance channel to connect with the outside atmosphere. This design brings several beneficial effects. First, the vent 22 provides a direct path for the labyrinth trough 21 to connect with the outside atmosphere, eliminating the need for other complex transition structures. This makes the overall gas flow path simpler and smoother. Whether the pressure inside the chamber 1 is negative due to the consumption of atomizing liquid or positive due to temperature rise or altitude changes, the gas can quickly enter and exit the labyrinth trough 21 through the vent 22, significantly improving the response speed of pressure balance and effectively avoiding atomizing liquid leakage caused by untimely pressure balance. In addition, the vent 22 is connected to the end of the labyrinth trough 21 away from the connecting groove 31, so that the gas inlet and outlet ends are staggered from the connection ends of the labyrinth trough 21 and the connecting groove 31, forming an orderly flow path of "outside - vent - labyrinth trough - connecting groove - chamber". This avoids mutual interference during gas flow and reduces the probability that the atomizing liquid in the chamber 1 will enter the labyrinth trough 21 through the connecting groove 31 and then come into contact with the vent 22, further enhancing the leak-proof effect.

[0045] In a specific embodiment, the bottom cover 2 is an injection molded part, and the labyrinth groove 21 is integrally injection molded with the bottom cover 2; the sealing element 3 is interference-fitted with the bottom of the chamber 1 and the top of the bottom cover 2.

[0046] The bottom cover 2 is manufactured using injection molding. During production, the entire structure is shaped in one go using a custom mold. The labyrinth groove 21 is not processed through subsequent cutting or carving; instead, its shape is pre-designed during the mold design phase. Therefore, the labyrinth groove 21 and the bottom cover 2 are injection molded simultaneously, forming a completely inseparable integrated structure with no seams or assembly interfaces between them. More specifically, the sealing element 3 is precisely sized. The parts that assemble with the bottom of the chamber 1 and those that fit against the top of the bottom cover 2 are slightly larger than their corresponding mounting surfaces. This design ensures a tight interference fit when the sealing element 3 is assembled to the bottom of the chamber 1 and fits against the bottom cover 2, preventing loosening, displacement, or gaps. The one-piece injection molding significantly simplifies the production process of the bottom cover 2 and the labyrinth groove 21, eliminating the need for additional processing steps. This not only improves production efficiency but also avoids dimensional deviations that may result from multi-process manufacturing, ensuring the precise shape and position of the labyrinth groove 21. Furthermore, the integrated structure enhances the overall strength of the bottom cover 2, making the labyrinth groove 21 less prone to deformation or damage during long-term use, thus extending the service life of the entire atomizing chamber. Moreover, the interference fit allows for a seamless fit between the seal 3 and the chamber 1 and bottom cover 2, completely blocking any leakage path of the atomizing liquid from these mating surfaces. This tight fit also makes the connection between the labyrinth groove 21 and the connecting groove 31 more stable, preventing gas leakage at the connection point and ensuring the sealing and flow efficiency of the air pressure balance channel.

[0047] In a specific embodiment, the side wall of the chamber 1 is provided with an oil-injecting silicone 11, which is embedded in the oil injection port of the chamber 1.

[0048] The side wall of chamber 1 has a pre-drilled filling port for refilling. The refill silicone 11 is embedded in this port, with its outer surface completely fitting the inner wall of the port. The silicone 11 is soft and elastic, allowing it to better fill the tiny gaps in the filling port after embedding, further improving the sealing effect. When refilling is needed, the filling needle can easily pierce the silicone 11 and enter the chamber 1. After refilling, the silicone 11 automatically rebounds and closes, restoring the seal. This embodiment achieves a reliable seal at the filling port, preventing leakage of the atomizing liquid from chamber 1. This aligns with the overall leak-proof requirements of the atomizing chamber, ensuring a superior user experience. Furthermore, the embedded design of the silicone 11 eliminates the need for an additional sealing cap or locking structure, simplifying the overall structure and making refilling more convenient. It can be completed without disassembling any parts, reducing the difficulty of use for the user.

[0049] After the atomizing chamber provided in Example 1 is assembled, the bottom cover 2 is integrally injection molded with a labyrinth groove 21. The sealing element 3 is interference-fitted with the bottom of the chamber 1 and the bottom cover 2. The oil-filling silicone 11 is embedded in the oil filling port of the chamber 1. The labyrinth groove 21 forms a closed loop through two transverse grooves 211 and two transition sections 212, which precisely connects with the connecting groove 31 on the sealing element 3. The vent 22 of the bottom cover 2 connects the labyrinth groove 21 with the outside, forming a complete air pressure balance channel. When filling with oil, the oil filling needle punctures the oil-filling silicone 11, and after filling, the silicone springs back to seal. During use, when a negative pressure is formed in the chamber 1 due to the consumption of atomizing liquid, the outside atmosphere enters the chamber 1 through the vent 22, the labyrinth groove 21, and the smooth inner wall of the connecting groove 31; when a positive pressure is formed due to the increase in temperature or the decrease in altitude, the internal gas is discharged in the opposite direction through the connecting groove 31, the labyrinth groove 21, and the vent 22, thus achieving air pressure balance. During the process, the closed loop of the labyrinth groove 21 blocks the atomizing liquid, the interference fit of the seal 3 and the silicone material prevent leakage, and the oil injection silicone 11 seals the oil injection port. All components work together to achieve air pressure balance and leak prevention.

[0050] Example 2 This embodiment provides an atomizing device, including the atomizing chamber, atomizing component 4, and electrode component 5 as described in Embodiment 1. The atomizing component 4 is disposed inside the lower part of the chamber 1. The electrode component 5 is disposed below the bottom cover 2. The electrode component 5 includes an electrode base 51, an electrode pin 52, and an electrode silicone 53. The electrode pin 52 passes through the electrode base 51, and the electrode silicone 53 is sleeved on the outside of the electrode pin 52. A magnet 23 is also provided below the bottom cover 2, and the magnet 23 is disposed adjacent to the electrode base 51.

[0051] The atomizing device in this embodiment uses the atomizing chamber described in Embodiment 1 as the core atomizing liquid storage unit. Based on this, the atomizing component 4 and the electrode component 5 are integrated to form a complete atomizing functional system. The atomizing component 4 is precisely positioned inside the lower part of the chamber 1. This position allows the atomizing component 4 to directly contact the atomizing liquid stored in the chamber 1, providing a continuous supply of raw materials for the atomizing operation. The electrode component 5 is assembled under the bottom cover 2, and is distributed vertically and vertically with the atomizing component 4 inside the chamber 1. The electrode component 5 includes an electrode base 51, an electrode nail 52, and an electrode silicone 53. The electrode base 51 serves as the mounting base for the electrode component 5, providing a stable support for the electrode nail 52. The electrode nail 52 passes through the electrode base 51 to achieve its fixed positioning. The electrode silicone 53 is sleeved on the outside of the electrode nail 52, covering the mating part between the electrode nail 52 and the electrode base 51. At the same time, a magnet 23 is also provided under the bottom cover 2. The magnet 23 is arranged adjacent to the electrode base 51, and the two maintain a compact and non-interfering distance. More specifically, after the electrode nail 52 passes through the electrode base 51, its end near the chamber 1 can be electrically connected to the atomizing component 4 to provide the power required for the atomizing component 4 to work. The electrode silicone 53 can fill the gap between the electrode nail 52 and the electrode base 51, and the magnet 23 can form an adsorption fit with the external device by means of magnetic force.

[0052] In addition, the atomizing component 4 is located inside the atomizing tube 7, and there is an oil storage cotton 6 between the atomizing component 4 and the inner wall of the atomizing tube 7.

[0053] This embodiment integrates the atomizing chamber, atomizing component 4, and electrode component 5, forming a complete functional chain from atomizing liquid storage to atomization operation and power supply, eliminating the need for additional components and improving the device's integration and ease of use. The atomizing component 4 is located inside the lower part of the chamber 1, allowing direct contact with the atomizing liquid and preventing insufficient atomization due to liquid position deviation, thus ensuring stable atomization effects. The electrode component 5 is located below the bottom cover 2, corresponding vertically to the atomizing component 4, shortening the electrical connection distance between the electrode pin 52 and the atomizing component 4, reducing power transmission loss. The electrode pin 52 passes through the electrode base 51, ensuring structural stability and preventing loosening or displacement during use. The electrode silicone 53 is sleeved on the outside of the electrode pin 52, achieving sealing and insulation between the electrode pin 52 and the electrode base 51, preventing external impurities from entering and causing short circuits, and also preventing leakage at the electrode area, thus improving the device's safety. Furthermore, the magnet 23 below the bottom cover 2 is arranged adjacent to the electrode base 51, which can use magnetic force to achieve quick adsorption and positioning of the atomizing device and external equipment, making it convenient for users to install and disassemble. At the same time, magnetic positioning can ensure accurate docking between the electrode assembly 5 and the external power supply equipment, avoiding power instability caused by docking deviation.
