Description

Technical Field

[0001] This utility model relates to the field of atomizing device technology, and in particular to an atomizing structure and atomizing device. Background Technology

[0002] In the development of the e-cigarette industry, product form is gradually shifting from traditional e-liquid reservoirs to clear e-liquid displays. Clear e-liquid products, due to their ability to visually display the e-liquid's state, have attracted considerable attention from the market and consumers, becoming one of the mainstream development directions in the industry.

[0003] However, current e-cigarette products commonly face the pressing technical challenge of leakage, a problem that can occur during transportation and actual use. Leakage not only severely impacts the user experience, leading to decreased customer satisfaction, but also directly negatively affects the overall sales of brands, hindering the market promotion and development of e-cigarette products with clear liquid coatings. Furthermore, leak-proof functionality is a crucial performance indicator for e-cigarette products and a key selling point for attracting consumers and enhancing product competitiveness. Therefore, resolving the leakage problem in e-cigarette products is of significant practical importance to the e-cigarette industry.

[0004] Analysis shows that e-liquid leakage in e-cigarettes is mainly affected by environmental factors, specifically in two ways: First, in high-temperature environments, the air and e-liquid inside the tank expand, causing a sharp increase in pressure. When the pressure exceeds a certain threshold, the e-liquid is forced out of the tank, resulting in leakage. Second, in high-altitude or high-flying environments, the external air pressure is significantly lower, leading to relatively high air pressure inside the tank, which also forces the e-liquid out, causing leakage. Ultimately, both of these leakage scenarios are primarily caused by the expansion of e-liquid and air within the tank. The problem of air expansion causing e-liquid overflow is particularly serious and is the main cause of leakage in e-liquid products. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an atomizing structure and atomizing device.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: In a first aspect, this utility model provides an atomizing structure, including: an oil cup, a sealing element, an outer support, an inner support, a top support, an oil storage element, and an atomizing core assembly. The sealing element is connected to the lower end of the inner support, the top support is disposed on the upper inner side of the oil cup, the lower end of the outer support is connected to the lower end of the inner support, and the upper end is connected to the top support. The oil cup, the top support, and the outer support enclose an oil storage cavity for holding e-liquid. The inner support is disposed on the inner side of the outer support, the oil storage element is disposed on the inner side of the inner support, and the atomizing core assembly is disposed on the inner side of the oil storage element. The outer side of the inner support is provided with a liquid passage communicating with the inner side of the inner support, the outer support is provided with a liquid passage hole communicating with the liquid passage, and the outer side of the inner support is also provided with an exhaust channel, the top end of which is connected to the oil storage cavity, and the lower end of which is connected to the inner side of the inner support. When the air inside the oil storage chamber expands, the expanded gas overflows along the vent gap between the top support and the oil cup and enters the exhaust channel until it enters the inner side of the inner support; and / or the expanded gas sequentially enters the inner side of the inner support along the liquid passage and the liquid channel.

[0007] In one specific embodiment, a top seal is provided above the top bracket, the top seal is sleeved on the inner bracket, and the top bracket is also provided with an air passage groove communicating with the air outlet gap, the air passage groove communicating with the exhaust channel.

[0008] In one specific embodiment, the liquid passage includes a U-shaped channel with an oil inlet end and an oil outlet end. The oil inlet end is connected to the liquid passage hole, and the oil outlet end is provided with a through hole connected to the inner side of the inner support. A micro groove is also provided between the oil inlet end and the oil outlet end, and the micro groove is connected to the through hole.

[0009] In one specific embodiment, the bottom of the exhaust channel is provided with a rectangular opening communicating with the inner side of the inner bracket, and the side of the exhaust channel away from the rectangular opening is provided with an opening groove communicating with the U-shaped channel.

[0010] In one specific embodiment, the cross-sectional area of ​​the micro-groove is smaller than the cross-sectional area of ​​the U-shaped channel.

[0011] In one specific embodiment, the inner support has a through cavity, the oil storage component is vertically disposed in the through cavity, and the top of the through cavity is connected to the top of the oil cup.

[0012] In one specific embodiment, the oil storage component and the inner wall of the passage cavity form an exhaust gap; when the expanded gas enters the inner side of the inner support, it flows from bottom to top along the exhaust gap until it enters the top of the oil cup and is discharged.

[0013] In one specific embodiment, the atomizing core assembly includes an atomizing tube, an air guide tube, an oil guide component, and a heating wire. The atomizing tube is located inside the oil storage component and its top is connected to the air guide tube. The air guide tube is connected to the passage cavity. The oil guide component is located inside the atomizing tube and has an oil guide port. The oil guide port is used to connect the oil storage component and the oil guide component. The heating wire is located inside the oil guide component.

[0014] The beneficial effects of the atomizing structure of this utility model compared with the prior art are as follows: When the atomizing device is placed vertically, the expanded gas overflows along the gas outlet gap between the top support and the oil cup and enters the exhaust channel until it enters the inner side of the inner support, and finally enters the top of the oil cup and is discharged; when the atomizing device is placed vertically upside down, the expanded gas sequentially enters the inner side of the inner support through the liquid passage and the liquid channel, and finally enters the top of the oil cup and is discharged; when the atomizing device is placed horizontally, a portion of the expanded gas overflows along the gas outlet gap between the top support and the oil cup and enters the exhaust channel until it enters the inner side of the inner support, while another portion of the expanded gas sequentially enters the inner side of the inner support through the liquid passage and the liquid channel. The gas finally enters the top of the oil cup and is then discharged. In other words, the e-liquid in the oil storage chamber can naturally permeate into the oil storage component through the liquid passage and liquid channel, and then the oil storage component continuously supplies e-liquid to the atomizing core component inside, ensuring sufficient and even e-liquid supply during atomization. At the same time, by constructing a gas flow path of "oil storage chamber - exhaust channel / liquid channel - inner side of the inner support - top of the oil cup", the air that expands in the oil storage chamber due to environmental factors such as high temperature and high altitude can be discharged in an orderly manner along the preset channel, rather than squeezing the e-liquid and causing leakage. No matter whether the atomizing device is placed vertically, vertically upside down or horizontally, the expanded gas can be depressurized through the corresponding path, solving the core problem of oil overflow caused by air expansion.

[0015] Secondly, this utility model provides an atomizing device, including a main unit and an atomizing structure as described above, wherein the main unit is used to provide electrical energy to the atomizing structure.

[0016] The advantages of this atomizing device compared to existing technologies are as follows: The main unit provides electrical energy to the atomizing structure. When the atomizing device is placed vertically, the expanded gas overflows along the gas outlet gap between the top support and the oil cup and enters the exhaust channel, until it enters the inner side of the inner support, and finally enters the top of the oil cup and is discharged. When the atomizing device is placed vertically upside down, the expanded gas sequentially enters the inner side of the inner support through the liquid inlet and liquid channel, and finally enters the top of the oil cup and is discharged. When the atomizing device is placed horizontally, a portion of the expanded gas overflows along the gas outlet gap between the top support and the oil cup and enters the exhaust channel, until it enters the inner side of the inner support; another portion of the expanded gas sequentially enters the inner support through the liquid inlet and liquid channel. Inside the support, the two gas paths finally enter the top of the oil cup and exit. In other words, the e-liquid in the oil storage chamber can naturally permeate into the oil storage component through the liquid passage and liquid channel, and then the oil storage component continuously supplies e-liquid to the atomizing core assembly inside, ensuring sufficient and even e-liquid supply during atomization. At the same time, by constructing a gas flow path of "oil storage chamber - exhaust channel / liquid channel - inside of the inner support - top of the oil cup", the air that expands in the oil storage chamber due to environmental factors such as high temperature and high altitude can be discharged in an orderly manner along the preset channel, rather than squeezing the e-liquid and causing leakage. No matter whether the atomizing device is placed vertically, vertically upside down or horizontally, the expanded gas can be depressurized through the corresponding path, solving the core problem of oil overflow caused by air expansion.

[0027] See Figures 1 to 9As shown, this utility model discloses a specific embodiment of an atomizing structure, including: an oil cup 10, a sealing element 20, an outer support 30, an inner support 40, a top support 50, an oil storage container 60, and an atomizing core assembly 70. The sealing element 20 is connected to the lower end of the inner support 40. The top support 50 is disposed on the upper inner side of the oil cup 10. The lower end of the outer support 30 is connected to the lower end of the inner support 40, and the upper end is connected to the top support 50. The oil cup 10, the top support 50, and the outer support 30 together form an oil storage cavity 80. 80 is used to hold e-liquid. The inner support 40 is disposed inside the outer support 30. The oil storage component 60 is disposed inside the inner support 40. The atomizing core assembly 70 is disposed inside the oil storage component 60. The outer side of the inner support 40 is provided with a liquid passage 41 communicating with the inner side of the inner support 40. The outer support 30 is provided with a liquid passage hole communicating with the liquid passage 41. The outer side of the inner support 40 is also provided with an exhaust channel 42, and the top end of the exhaust channel 42 is connected to the oil storage chamber 80, and the lower end is connected to the inner side of the inner support 40. When the air inside the oil storage chamber 80 expands, the expanded gas overflows through the air outlet gap between the top support 50 and the oil cup 10 and enters the exhaust channel 42 until it enters the inner side of the inner support 40; and / or the expanded gas sequentially enters the inner side of the inner support 40 through the liquid passage hole and the liquid passage 41.

[0028] Specifically, the oil cup 10 is made of transparent quartz glass or transparent plastic and has a cylindrical hollow structure. The transparent material allows for a direct view of the e-liquid state inside the oil storage chamber 80, meeting the core requirements of open-oil products. The sealing element 20 is fitted onto the lower end of the inner bracket 40 and abuts against the inner wall of the oil cup 10, serving to seal the oil storage chamber 80. The outer bracket 30 is fixed to the inner bracket 40 with an interference fit. The inner bracket 40 is coaxially positioned inside the outer bracket 30. Several evenly distributed exhaust channels 42 are opened along the axial direction on the outer side of the inner bracket 40. The top end of each exhaust channel 42 connects to the oil storage chamber 80, and the bottom end connects to the inner side of the inner bracket 40. At the same time, four symmetrically distributed liquid passages 41 are also opened on the side wall of the inner bracket 40, which are connected to the corresponding liquid passage holes on the side wall of the outer bracket 30. The top bracket 50 is fixed to the upper end of the outer bracket 30 using a tight fit. A pre-reserved air outlet gap is provided between the top bracket 50 and the inner wall of the oil cup 10, which serves as a transitional connection structure between the oil storage chamber 80 and the exhaust channel 42. The oil storage component 60 is made of polymer absorbent cotton, which fills the inner side of the inner bracket 40, and its outer side is tightly fitted to the inner wall of the inner bracket 40. The atomizing core assembly 70 includes wicking cotton and a heating wire. The wicking cotton wraps around the heating wire and is embedded inside the oil storage component 60. The wicking cotton contacts the oil storage component 60 to achieve the adsorption and delivery of e-liquid.

[0029] See Figure 5 and Figure 6 As shown, when the atomizer is placed vertically, the e-liquid in the oil reservoir 80 concentrates at the bottom due to gravity, while air remains at the top. In high-temperature or high-altitude environments, the air at the top expands due to heat or low pressure. The expanding gas first overflows through the air outlet gap between the top support 50 and the oil cup 10, then enters the exhaust channel 42 on the outside of the inner support 40, and then flows downward along the exhaust channel 42 to the inside of the inner support 40. The gas entering the inside of the inner support 40 has a lower density than the e-liquid, so it will rise and converge to the top of the oil cup 10 (i.e., the mouthpiece), and finally be discharged outside the atomizer, completing the pressure release.

[0030] See Figure 7 and Figure 8 As shown, when the atomizing device is placed vertically upside down, the e-liquid in the oil storage chamber 80 covers the air outlet gap between the top bracket 50 and the oil cup 10, preventing the gas from escaping through this path. At this time, the expanding gas turns to the liquid passage hole of the outer bracket 30 and passes through the liquid passage hole and the liquid passage channel 41 in sequence to enter the inner side of the inner bracket 40. After entering the inner side of the inner bracket 40, the gas breaks through the gap of the oil storage component 60 and flows upward, also converging at the top of the oil cup 10 and being discharged, thus preventing pressure buildup in the oil storage chamber 80.

[0031] See Figure 9 As shown, when the atomizing device is placed horizontally, the e-liquid in the oil storage chamber 80 is evenly distributed on both sides, and air exists simultaneously in the top and middle areas. The expanding gas is discharged in two paths. One path enters the exhaust channel 42 through the air outlet gap at the top that is not covered by e-liquid, and finally reaches the inner side of the inner bracket 40. The other path enters the liquid passage channel 41 through the liquid passage hole in the lower half of the outer bracket 30, and is also introduced into the inner side of the inner bracket 40. After the two gas paths merge on the inner side of the inner bracket 40, they are discharged together through the top of the oil cup 10, realizing pressure distribution in all postures.

[0032] In other words, the e-liquid in the oil storage chamber 80 can naturally permeate into the oil storage component 60 through the liquid passage hole and liquid passage 41, and then the oil storage component 60 continuously supplies e-liquid to the atomizing core assembly 70 inside. The oil-guiding cotton continuously absorbs e-liquid from the oil storage component 60 to supply the heating wire, avoiding dry burning and ensuring sufficient and even e-liquid supply during atomization. At the same time, by constructing a gas flow path of "oil storage chamber 80 - exhaust channel 42 / liquid passage 41 - inner side of inner support 40 - top of oil cup 10", the air that expands in the oil storage chamber 80 due to environmental factors such as high temperature and high altitude can be discharged in an orderly manner along the preset channel, rather than squeezing the e-liquid and causing leakage. No matter whether the atomizing device is placed vertically, vertically upside down or horizontally, the expanded gas can be depressurized through the corresponding path, solving the core problem of oil overflow caused by air expansion.

[0033] See Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, in one embodiment, a top seal 90 is provided above the top bracket 50, the top seal 90 is sleeved on the inner bracket 40, and the top bracket 50 is also provided with an air passage groove 51 communicating with the air outlet gap, the air passage groove 51 communicating with the exhaust channel 42.

[0034] Specifically, the top seal 90 is supported by the top bracket 50 and is fixedly attached to the top of the oil cup 10; at the same time, the top seal 90 is fixed to the upper end of the inner bracket 40 by a tight fit, realizing a detachable fixed connection with the inner bracket 40. The top bracket 50 has four air passage grooves 51 evenly distributed around its circumference. One end of each air passage groove 51 is connected to the air outlet gap. The outer bracket 30 has a notch corresponding to the air passage groove 51. The other end of the air passage groove 51 is connected to the top opening of the exhaust channel 42 on the outer side of the inner bracket 40 through the notch, forming a continuous gas flow channel of "air outlet gap → air passage groove 51 → exhaust channel 42".

[0035] When the atomizing device is placed vertically, as the air in the oil reservoir 80 expands, the expanded gas first enters the air outlet gap between the top support 50 and the oil cup 10. Since the air outlet gap is directly connected to the air passage 51, the gas is then guided through the air passage 51 to the exhaust channel 42 of the inner support 40, and then flows downwards along the exhaust channel 42 into the inner side of the inner support 40, finally exiting from the top of the oil cup 10. The air passage 51 guides the gas, preventing it from stagnating in the air outlet gap. The top seal 90 acts as a seal, preventing e-liquid from overflowing, and simultaneously seals the oil reservoir 80, ensuring that the inside of the oil reservoir 80 is a sealed space, thus creating negative pressure.

[0036] When the atomizing device is placed horizontally, the e-liquid is evenly distributed in the oil storage chamber 80. Part of the air outlet gap is covered. One path of expanding gas enters the air passage 51 through the uncovered air outlet gap, and then enters the exhaust channel 42 through the air passage 51. At the same time, another path of gas is discharged through the liquid passage 41. The circumferential distribution design of the air passage 51 ensures that gas can quickly enter any one of the exhaust channels 42 in a horizontal state, improving the channeling efficiency.

[0037] See Figures 2 to 9 As shown, in one embodiment, the liquid passage 41 includes a U-shaped channel 411 having an oil inlet end 412 and an oil outlet end 413. The oil inlet end 412 is connected to the liquid passage hole, and the oil outlet end 413 is provided with a through hole 414 connected to the inner side of the inner support 40. A micro groove 415 is also provided between the oil inlet end 412 and the oil outlet end 413, and the micro groove 415 is connected to the through hole 414.

[0038] Specifically, the U-shaped channel 411 is a rectangular cross-section channel that extends horizontally along the side wall of the inner support 40 and meanders in a U-shape. The meandering design increases the length of the e-liquid flow path. The e-liquid outlet 413 is connected to the circular through hole 414, which penetrates the inner side wall of the inner support 40 and leads directly to the inner side of the inner support 40. The micro-slot 415 is an arc-shaped narrow slot located between the e-liquid inlet 412 and the e-liquid outlet 413. One end of the micro-slot 415 is connected to the e-liquid inlet 412, and the other end is directly connected to the through hole 414, forming a shortcut flow channel of "e-liquid inlet 412 → micro-slot 415 → through hole 414". The total length of the micro-slot 415 is much shorter than the length of the U-shaped channel 411.

[0039] During normal use, the e-liquid in the oil storage chamber 80, under the influence of gravity and concentration difference, enters the oil inlet end 412 of the inner support 40 through the liquid passage of the outer support 30. After entering the oil inlet end 412, the narrow cross-section of the micro groove 415 creates significant resistance to the flow of e-liquid, while the groove width and depth of the U-shaped channel 411 are larger and the flow resistance is smaller. Therefore, the e-liquid flows slowly along the U-shaped channel 411, making full contact with the channel wall during the process to ensure stable flow. Finally, the e-liquid permeates through the through hole 414 at the end of the oil outlet end 413 into the oil storage component 60 inside the inner support 40. After absorbing the e-liquid, the oil storage component 60 continuously supplies oil to the atomizing core assembly 70, achieving uniform oil guidance.

[0040] When the atomizing device is placed vertically upside down, and the expanding gas cannot be discharged through the top air outlet gap, the gas enters the oil inlet 412 through the liquid passage. Since the gas flow is much better than that of e-liquid, and the flow channel of the micro groove 415 is short and has low resistance, most of the expanding gas flows directly through the micro groove 415 to the through hole 414 and enters the inner side of the inner support 40. A small amount of gas enters the U-shaped channel 411 due to diffusion, and after meandering along the U-shaped channel 411, it also enters the inner side of the inner support 40 through the through hole 414. After the two gas paths converge on the inner side of the inner support 40, they are discharged through the top of the oil cup 10, completing the pressure relief.

[0041] In other words, the liquid passage 41 achieves precise diversion of e-liquid delivery and gas depressurization through the differentiated design of "U-shaped channel 411 + micro-groove 415". The meandering structure of the U-shaped channel 411 extends the e-liquid flow path and slows down the e-liquid flow rate, ensuring that the oil storage component 60 absorbs oil evenly and avoiding oil overflow caused by the e-liquid rushing into the inner side of the inner support 40 too quickly. The micro-groove 415 provides a shortcut for gas flow, allowing the expanded gas to be discharged quickly and improving the pressure release efficiency. The two have clear division of labor and are compatible with each other, solving the problem of "mutual interference between e-liquid delivery and gas depressurization" in traditional single channels, and achieving the dual effect of "stable oil delivery and fast pressure depressurization".

[0042] See Figure 4 and Figure 7As shown, in one embodiment, the cross-sectional area of ​​the micro-groove 415 is smaller than the cross-sectional area of ​​the U-shaped channel 411.

[0043] Specifically, the U-shaped channel 411 is designed as a rectangular cross-section channel with a width of 1.0 mm and a depth of 0.8 mm. The overall meandering extension length is about 20 mm. The inner wall of the channel is polished to reduce the resistance to e-liquid flow. The micro-channel 415 is also rectangular in cross-section, with a width of only 0.3 mm, a depth of 0.2 mm, and a length controlled within 2 mm. Its width and depth are only 30% and 25% of the U-shaped channel 411, respectively. Furthermore, the connection between the micro-channel 415 and the oil inlet 412 and the through hole 414 is rounded to reduce gas flow obstruction.

[0044] When the atomizing structure is placed upright or horizontally, after the e-liquid in the oil storage chamber 80 enters the oil inlet 412 through the liquid passage, due to the certain viscosity of the e-liquid (the viscosity of e-liquid at room temperature is about 50-100 mPa·s), the narrow cross-section of the micro-groove 415 generates a large flow resistance. Under the action of pressure difference, the e-liquid tends to flow through the U-shaped channel 411, which has a wider and deeper groove, and slowly permeates through the U-shaped channel 411 to the through hole 414, and finally enters the oil storage component 60 inside the inner support 40. The e-liquid passing through the micro-groove 415 has a large flow resistance and a very small flow rate, which can be almost ignored, ensuring that the e-liquid is mainly transported through the U-shaped channel 411.

[0045] When the atomizing structure is inverted, the expanding gas enters the oil inlet 412. Due to the extremely low viscosity of the gas (air viscosity is about 0.018 mPa·s), its sensitivity to channel size is much lower than that of e-liquid. The gas can quickly break through the narrow cross-section of the micro-groove 415 and flow directly to the through hole 414 with low flow resistance, entering the inner side of the inner support 40. At this time, the micro-groove 415 becomes the main path for gas pressure relief, and the remaining small amount of gas is discharged along the U-shaped channel 411. The dual paths work together to achieve rapid pressure relief.

[0046] In other words, through differentiated size design, the viscosity difference between e-liquid and gas is utilized to achieve "adaptive flow separation." E-liquid, due to its high viscosity, naturally flows through the low-resistance U-shaped channel 411, ensuring stable wicking. Gas, with its low viscosity, can be quickly discharged through the higher-resistance micro-groove 415, achieving efficient pressure relief. Both flow through the same channel structure without interference, resolving the contradiction of traditional channels where "e-liquid easily clogs the airflow, and gas easily carries oil." Simultaneously, the main pressure relief function of the micro-groove 415 when the device is inverted allows expanding gas to be quickly discharged without accumulating in the oil reservoir 80, far below the pressure threshold for e-liquid leakage. This enhances the reliability of all-position leak prevention, allowing users to store the device in their pockets or upside down without worrying about leakage.

[0047] See Figure 4As shown, in one embodiment, the bottom of the exhaust channel 42 is provided with a rectangular opening 421 communicating with the inner side of the inner support 40, and the side of the exhaust channel 42 away from the rectangular opening 421 is provided with an opening groove 422 communicating with the U-shaped channel 411.

[0048] Specifically, a rectangular opening 421 is located at the bottom end of the exhaust channel 42. It has a rectangular structure and directly penetrates the side wall of the inner support 40, connecting to the inner side of the inner support 40. The edges of the rectangular opening 421 are rounded to avoid turbulent resistance during gas flow. An opening groove 422 is located on the side of the exhaust channel 42 away from the rectangular opening 421. It has a U-shaped groove structure, with a width of 0.8 mm and a depth of 0.5 mm. One end connects to the exhaust channel 42, and the other end extends to the side wall of the U-shaped channel 411, connecting with the U-shaped channel 411 to form an auxiliary flow channel: "exhaust channel 42 → opening groove 422 → U-shaped channel 411 → inner side of inner support 40".

[0049] When a user inhales from the atomizing device, the heating wire of the atomizing core assembly 70 heats the e-liquid to produce vapor. The e-liquid inside the inner support 40 is continuously consumed, and the e-liquid in the oil reservoir 80 is replenished to the inner support 40 through the liquid passage 41. At this time, a slight negative pressure is formed in the oil reservoir 80 due to the reduction of e-liquid. Under the action of pressure difference, outside air enters the inner support 40 through the top of the oil cup 10, and then enters the exhaust passage 42 through the rectangular opening 421 at the bottom of the exhaust passage 42. It flows upward along the exhaust passage 42 to the oil reservoir 80, filling the space created by the consumption of e-liquid, so that the pressure in the oil reservoir 80 always maintains a dynamic balance with the outside.

[0050] When outside air enters the oil storage chamber 80 through the exhaust channel 42, since the opening groove 422 of the exhaust channel 42 is connected to the U-shaped channel 411, the e-liquid can flow into the exhaust channel 42 through the U-shaped channel 411 and the opening groove 422. The e-liquid forms a liquid seal layer in the exhaust channel 42, which prevents the oil storage chamber 80 from directly forming a through channel with the outside, ensuring that the oil storage chamber 80 maintains the required negative pressure state and preventing a large amount of air from seeping in and disrupting the negative pressure balance.

[0051] In other embodiments, the opening groove 422 can also be directly connected to the oil storage chamber 80 through a preset oil guiding structure, so that the e-liquid flows into the exhaust channel 42 through the oil guiding structure, thereby forming a liquid seal layer in the exhaust channel 42.

[0052] See Figure 2 and Figure 3 As shown, in one embodiment, the inner support 40 is provided with a through cavity, the oil storage component 60 is vertically disposed in the through cavity, and the top of the through cavity is connected to the top of the oil cup 10.

[0053] Specifically, the inner support 40 has a cylindrical cavity along the axial direction, and the inner wall is smoothed to reduce airflow resistance. The oil reservoir 60 is vertically positioned in the cavity, which can quickly absorb the e-liquid flowing in through the through hole 414.

[0054] The top of the cavity extends to the upper end face of the inner support 40 and communicates with the inner space of the top of the oil cup 10. Finally, it connects with the outside through the top of the oil cup 10, forming a longitudinal airflow channel of "through hole 414 → cavity → top of oil cup 10 → outside".

[0055] In other words, the gas entering the inner side of the inner support 40 through the exhaust channel 42 and the gas entering through the liquid passage 41 move vertically upward along the passage and are finally discharged from the top of the oil cup 10. In addition, the balance air supplied to the inner side of the inner support 40 during the suction process can also be discharged through the passage after the pressure of the oil storage chamber 80 is replenished, ensuring dynamic pressure stability.

[0056] See Figure 6 and Figure 8 As shown, in one embodiment, the oil storage component 60 forms an exhaust gap with the inner wall of the cavity; when the expanded gas enters the inner side of the inner support 40, it flows from bottom to top along the exhaust gap until it enters the top of the oil cup 10 and is discharged.

[0057] Specifically, in the assembly structure of the oil reservoir 60 and the inner support 40, the oil reservoir 60 adopts a design in which the outer peripheral wall and the inner wall of the cavity are not tightly fitted, so that an annular exhaust gap is formed between the two. This gap extends through the inner support 40 axially, with its lower end communicating with the through hole 414 and its upper end extending to the top of the inner support 40 and connecting with the exhaust channel at the top of the oil cup 10.

[0058] After the expanded gas enters the inner side of the inner support 40, it flows from bottom to top along the exhaust gap formed between the oil reservoir 60 and the inner wall of the inner support 40. Since the exhaust gap is set around the outer periphery of the oil reservoir 60, the gas is not hindered by the oil adsorbed by the oil reservoir 60 during the flow process, and can rise smoothly along the gap. Finally, it is discharged to the outside through the connecting structure between the top of the inner support 40 and the top of the oil cup 10, completing the entire pressure relief process.

[0059] In one embodiment, the atomizing core assembly 70 includes an atomizing tube, an air guide tube, an oil guide element, and a heating wire. The atomizing tube is located inside the oil storage component 60 and its top is connected to the air guide tube. The air guide tube is connected to the passage cavity. The oil guide element is located inside the atomizing tube and has an oil guide port. The oil guide port is used to connect the oil storage component 60 and the oil guide element. The heating wire is located inside the oil guide element.

[0060] Specifically, the atomizing tube is made of 304 stainless steel, and the air guide tube is made of plastic or fiber optic tubing. Both the atomizing tube and the air guide tube have a cylindrical hollow structure, and their outer diameter matches the inner dimensions of the oil reservoir 60. They are fitted into the center of the oil reservoir 60 by an interference fit. The top opening of the atomizing tube is aligned with the bottom of the air guide tube, forming a smoke flow path of "atomizing tube → air guide tube → top of oil cup 10". The side wall of the atomizing tube is evenly provided with 4 sets of oil guide ports along the circumference, and each set of oil guide ports has 2 circular holes (or square holes). The oil guide component is made of high-polymer composite oil-guiding cotton, and is cylindrical in shape. It fills the inside of the atomizing tube, and its outer wall is tightly attached to the inner wall of the atomizing tube. The height of the oil guide component covers the oil guide port area of ​​the atomizing tube. The heating wire is made of nickel-chromium alloy and is spirally wound around the center of the oil guide component. The two ends of the heating wire extend through the insulating base (made of ceramic material) at the bottom of the atomizing tube to the external circuit. It is connected to the power supply through the pins to achieve power heating.

[0061] When the atomizing structure is powered on, the e-liquid absorbed by the oil reservoir 60 permeates through the oil guide port on the side wall of the atomizing tube into the oil guide inside the atomizing tube. The oil guide uses its own capillary action to evenly absorb and transport the e-liquid to the heating wire area. After the heating wire is powered on, it quickly heats up to 180-220℃. The area of ​​the oil guide in contact with the heating wire is heated, and the e-liquid is heated and atomized to form smoke. Under the negative pressure of the user's inhalation, the smoke rises into the air guide tube connected to the top of the atomizing tube, and then flows along the air guide tube to the mouthpiece at the top of the oil cup 10, and is finally inhaled by the user.

[0062] This utility model also discloses an atomizing device, including a host 100 and an atomizing structure as described above, wherein the host 100 is used to provide electrical energy to the atomizing structure.

[0063] Specifically, the main unit 100 provides electrical power to the atomizing structure. When the atomizing device is placed vertically, the expanded gas overflows along the air outlet gap between the top support 50 and the oil cup 10 and enters the exhaust channel 42, until it enters the inner side of the inner support 40, and finally enters the top of the oil cup 10 and is discharged. When the atomizing device is placed vertically upside down, the expanded gas passes through the liquid hole and the liquid passage 41 in sequence, enters the inner side of the inner support 40, and finally enters the top of the oil cup 10 and is discharged. When the atomizing device is placed horizontally, part of the expanded gas overflows along the air outlet gap between the top support 50 and the oil cup 10 and enters the exhaust channel 42, until it enters the inner side of the inner support 40, while another part of the expanded gas passes through the liquid hole and the liquid passage 41 in sequence, entering the inner side of the inner support 40. The gas finally enters the top of the oil cup 10 and is discharged; that is, the e-liquid in the oil storage chamber 80 can naturally permeate into the oil storage component 60 through the liquid passage hole and the liquid passage 41, and then the oil storage component 60 continuously supplies oil to the atomizing core component 70 inside, ensuring that the e-liquid supply is sufficient and uniform during the atomization process; at the same time, by constructing a gas flow path of "oil storage chamber 80 - exhaust channel 42 / liquid passage 41 - inner side of inner support 40 - top of oil cup 10", the air that expands in the oil storage chamber 80 due to environmental factors such as high temperature and high altitude can be discharged in an orderly manner along the preset channel, rather than squeezing the e-liquid and causing leakage; regardless of whether the atomizing device is placed vertically, vertically upside down or horizontally, the expanded gas can be depressurized through the corresponding path, solving the core problem of oil overflow caused by air expansion.

[0064] The host 100 uses existing publicly available technology, which will not be elaborated on here.

[0065] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
