Description

Technical Field

[0001] This utility model relates to the field of atomizing device technology, and in particular to an atomizer 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 utility model is to overcome the shortcomings of the prior art and provide an atomizer 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 atomizer, comprising: an oil cup, a bottom seal, an outer bracket, an inner bracket, a top bracket, an oil storage component, and an atomizing core assembly. The bottom seal is connected to the lower end of the oil cup, the top bracket is disposed on the upper inner side of the oil cup, the lower end of the outer bracket is connected to the lower end of the inner bracket, and the upper end is connected to the top bracket. The oil cup, the top bracket, and the outer bracket together form a main oil storage chamber for holding e-liquid. The inner bracket and the bottom seal together form a secondary oil storage chamber. The inner bracket is disposed on the inner side of the outer bracket, the oil storage component is disposed in the secondary oil storage chamber, and the atomizing core assembly is disposed on the inner side of the oil storage component. The inner bracket has a liquid passage communicating with the secondary oil storage chamber, the outer bracket has a liquid passage hole communicating with the liquid passage, and the outer side of the inner bracket also has an exhaust channel, the top end of which is connected to the main oil storage chamber, and the bottom end of which is connected to the secondary oil storage chamber. When the air inside the main oil storage chamber expands, the expanded gas overflows through the vent gap between the top support and the oil cup and enters the exhaust channel until it enters the secondary oil storage chamber; and / or the expanded gas sequentially enters the secondary oil storage chamber through 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 vertical channel and a U-shaped channel. The top of the vertical channel is connected to the liquid passage hole, and the bottom is connected to the U-shaped channel. The end point of the U-shaped channel is provided with a through hole connected to the secondary oil storage chamber. Furthermore, a micro groove is provided at the connection between the vertical channel and the U-shaped channel, 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 that communicates with the secondary oil storage chamber, and the side of the exhaust channel away from the rectangular opening is provided with an opening groove that communicates 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 is further provided with an annular retaining sleeve in the area of ​​the secondary oil storage cavity. The annular retaining sleeve, together with the bottom seal and the inner wall of the inner support, forms an isolation cavity. The isolation cavity is connected to the through hole and the secondary oil storage cavity.

[0012] In one specific embodiment, the inner support is provided with a through cavity, the bottom of which is connected to the secondary oil storage cavity and the top of which is connected to the top of the oil cup.

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

[0014] In one specific embodiment, a bottom cover is also provided between the bottom seal and the oil cup.

[0015] The beneficial effects of this atomizer compared to existing technologies are as follows: When the atomizing device is placed vertically, the expanded gas overflows along the air outlet gap between the top support and the oil cup and enters the exhaust channel until it enters the secondary oil storage chamber, 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 secondary oil storage chamber 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, part of the expanded gas overflows along the air outlet gap between the top support and the oil cup and enters the exhaust channel until it enters the secondary oil storage chamber, while another part of the expanded gas sequentially enters the secondary oil storage chamber through the liquid inlet and liquid channel, and both gas streams finally enter the top of the oil cup and are discharged; that is... In other words, an oil reservoir is installed in the secondary oil reservoir formed by the inner support and the bottom seal. The e-liquid in the main oil reservoir can naturally permeate into the oil reservoir through the liquid passage and liquid channel, and then the oil reservoir 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 "main oil reservoir - exhaust channel / liquid channel - secondary oil reservoir - top of oil cup", the air that expands in the main oil reservoir 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.

[0016] Secondly, this utility model provides an atomizing device, including a main unit and an atomizer as described above, wherein the main unit is used to provide electrical energy to the atomizer.

[0017] The advantages of this atomizing device compared to existing technologies are as follows: The main unit provides power to the atomizer. When the atomizing device is placed vertically, the expanded gas overflows through the air outlet gap between the top support and the oil cup and enters the exhaust channel, eventually entering the secondary oil storage chamber, and finally exiting from the top of the oil cup. When the atomizing device is placed vertically upside down, the expanded gas sequentially enters the secondary oil storage chamber through the liquid inlet and liquid channel, and finally exits from the top of the oil cup. When the atomizing device is placed horizontally, part of the expanded gas overflows through the air outlet gap between the top support and the oil cup and enters the exhaust channel, eventually entering the secondary oil storage chamber; another part of the expanded gas sequentially enters the secondary oil storage chamber through the liquid inlet and liquid channel, and both gas streams finally enter the top of the oil cup. The system features a dual-exhaust system; that is, an oil reservoir is installed within the secondary oil reservoir formed by the inner support and the bottom seal. E-liquid in the main oil reservoir can naturally permeate into the oil reservoir through the liquid passage and liquid channel, and then the oil reservoir continuously supplies oil 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 "main oil reservoir - exhaust channel / liquid channel - secondary oil reservoir - top of oil cup", the air that expands in the main oil reservoir 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.

[0028] See Figures 1 to 8As shown, this utility model discloses a specific embodiment of an atomizer, including: an oil cup 10, a bottom seal 20, an outer bracket 30, an inner bracket 40, a top bracket 50, an oil storage container 60, and an atomizing core assembly 70. The bottom seal 20 is connected to the lower end of the oil cup 10. The top bracket 50 is disposed on the upper inner side of the oil cup 10. The lower end of the outer bracket 30 is connected to the lower end of the inner bracket 40, and the upper end is connected to the top bracket 50. The oil cup 10, the top bracket 50, and the outer bracket 30 enclose a main oil storage chamber 80, which is used to hold e-liquid. The inner support 40 and the bottom seal 20 enclose each other to form a secondary oil storage chamber 90. The inner support 40 is disposed inside the outer support 30. The oil storage component 60 is disposed in the secondary oil storage chamber 90. The atomizing core assembly 70 is disposed inside the oil storage component 60. The inner support 40 is provided with a liquid passage 41 communicating with the secondary oil storage chamber 90. 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 main oil storage chamber 80, and the bottom end is connected to the secondary oil storage chamber 90. When the air inside the main 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 secondary oil storage chamber 90; and / or the expanded gas enters the secondary oil storage chamber 90 sequentially through the liquid passage hole and the liquid passage 41.

[0029] 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 main oil storage chamber 80, meeting the core requirements of open-oil products. The bottom seal 20 is fixed by the bottom cover 120, which is secured to the oil cup 10 by a snap-fit. The bottom seal 20 has a pre-drilled circular mounting hole for positioning and assembling the inner bracket 40. 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, and its lower end is interference-fitted with the bottom seal 20. Together, they form an annular secondary oil storage chamber 90. Several evenly distributed exhaust channels 42 are opened axially on the outer side of the inner bracket 40. The top of each exhaust channel 42 connects to the main oil storage chamber 80, and the lower end connects to the secondary oil storage chamber 90. 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. This gap serves as a transitional connection structure between the main oil storage chamber 80 and the exhaust channel 42. The oil storage component 60 is made of polymer absorbent cotton and is filled in the secondary oil storage chamber 90. 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 is in contact with the oil storage component 60 to achieve the adsorption and delivery of e-liquid.

[0030] When the atomizer is placed vertically, the e-liquid in the main 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 e-liquid cup 10, then enters the exhaust channel 42 on the outside of the inner support 40, and flows downward along the exhaust channel 42 to the secondary reservoir 90. The gas entering the secondary reservoir 90, being less dense than the e-liquid, will rise and converge to the top of the e-liquid cup 10 (i.e., the mouthpiece), and finally be discharged outside the atomizer, completing the pressure release.

[0031] When the atomizing device is placed vertically upside down, the e-liquid in the main 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 liquid passage 41 in sequence to enter the secondary oil storage chamber 90. After entering the secondary oil storage chamber 90, 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 main oil storage chamber 80.

[0032] When the atomizing device is placed horizontally, the e-liquid in the main oil reservoir 80 is evenly distributed on both sides, and air exists in the top and middle areas at the same time. The expanding gas is discharged in two ways. One way enters the exhaust channel 42 through the air outlet gap at the top that is not covered by e-liquid, and finally reaches the secondary oil reservoir 90. The other way 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 secondary oil reservoir 90. After the two gas paths merge in the secondary oil reservoir 90, they are discharged together through the top of the oil cup 10, realizing pressure distribution in all postures.

[0033] In other words, an oil storage component 60 is installed inside the secondary oil storage chamber 90 formed by the inner support 40 and the bottom seal 20. The e-liquid in the main oil storage chamber 80 can naturally permeate into the oil storage component 60 through the liquid passage hole and the liquid passage 41. 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 "main oil storage chamber 80 - exhaust channel 42 / liquid passage 41 - secondary oil storage chamber 90 - top of oil cup 10", the air that expands in the main 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.

[0034] See Figure 2 , Figure 5 and Figure 6 As shown, in one embodiment, a top seal 100 is provided above the top bracket 50. The top seal 100 is sleeved on the inner bracket 40. The top bracket 50 is also provided with an air passage groove 51 that communicates with the air outlet gap and the air passage groove 51 communicates with the exhaust channel 42.

[0035] Specifically, the top seal 100 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 100 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".

[0036] When the atomizing device is placed vertically, as the air in the main 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 downwards along the exhaust channel 42 into the secondary oil reservoir 90, 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 100 provides a seal, preventing e-liquid from overflowing, and simultaneously seals the main oil reservoir 80, ensuring that the interior of the main oil reservoir 80 is a sealed space, thus creating negative pressure.

[0037] When the atomizing device is placed horizontally, the e-liquid is evenly distributed in the main 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 the gas can quickly enter any one of the exhaust channels 42 in a horizontal state, improving the channeling efficiency.

[0038] See Figures 2 to 8 As shown, in one embodiment, the liquid passage 41 includes a vertical passage 411 and a U-shaped passage 412. The top of the vertical passage 411 is connected to the liquid passage hole, and the bottom is connected to the U-shaped passage 412. The end point of the U-shaped passage 412 is provided with a through hole 413 connected to the auxiliary oil storage chamber 90. A micro groove 43 is also provided at the connection between the vertical passage 411 and the U-shaped passage 412, and the micro groove 43 is connected to the through hole 413.

[0039] Specifically, the vertical channel 411 is a cylindrical, rectangular, triangular, or semi-circular channel, etc., opened along the axial direction of the inner support 40. Its top opening is precisely aligned with the liquid passage hole of the outer support 30, and the two are connected by a transition rounded corner to ensure smooth flow. The bottom is vertically connected to the starting end of the U-shaped channel 412. The U-shaped channel 412 is a rectangular cross-section channel that extends horizontally along the side wall of the inner support 40 and is distributed in a U-shape. The meandering design increases the length of the e-liquid flow path. Its end point is connected to the circular through hole 413, which penetrates the inner side wall of the inner support 40 and leads directly to the secondary oil storage chamber 90. The micro-groove 43 is an arc-shaped narrow groove, which is opened at the corner where the vertical channel 411 and the U-shaped channel 412 meet. One end is connected to the bottom of the vertical channel 411, and the other end is directly connected to the through hole 413 at the end of the U-shaped channel 412, forming a shortcut flow channel of "vertical channel 411 → micro-groove 43 → through hole 413". The total length of the micro-groove 43 is much shorter than the length of the U-shaped channel 412.

[0040] During normal use, the e-liquid in the main oil storage chamber 80, under the influence of gravity and concentration difference, enters the vertical channel 411 of the inner support 40 through the liquid passage of the outer support 30. After entering the vertical channel 411, the narrow cross-section of the micro groove 43 creates significant resistance to the flow of e-liquid, while the wider and deeper groove of the U-shaped channel 412 results in less flow resistance. Therefore, the e-liquid flows slowly along the U-shaped channel 412, making full contact with the channel wall to ensure stable flow. Finally, the e-liquid permeates through the through hole 413 at the end of the U-shaped channel 412 into the oil storage component 60 of the secondary oil storage chamber 90. After absorbing the e-liquid, the oil storage component 60 continuously supplies oil to the atomizing core assembly 70, achieving uniform oil guidance.

[0041] 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 vertical channel 411 through the liquid passage. Since the gas flow is much better than that of e-liquid, and the flow channel of the micro-groove 43 is short and has low resistance, most of the expanding gas flows directly through the micro-groove 43 to the through hole 413 and enters the secondary oil storage chamber 90. A small amount of gas enters the U-shaped channel 412 due to diffusion, and after meandering along the U-shaped channel 412, it also enters the secondary oil storage chamber 90 through the through hole 413. After the two gas paths converge in the secondary oil storage chamber 90, they are discharged through the top of the oil cup 10, completing the pressure relief.

[0042] 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 412 + micro-groove 43". The meandering structure of the U-shaped channel 412 extends the e-liquid flow path, slows down the e-liquid flow rate, ensures that the oil storage component 60 absorbs oil evenly, and avoids e-liquid from rushing into the secondary oil storage chamber 90 too quickly, which would cause oil overflow. The micro-groove 43 provides a shortcut for gas, 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, which solves the problem of "mutual interference between e-liquid delivery and gas depressurization" in traditional single channels, and achieves the dual effect of "stable oil delivery and fast pressure depressurization".

[0043] See Figure 4 and Figure 7 As shown, in one embodiment, the cross-sectional area of ​​the micro-groove 43 is smaller than the cross-sectional area of ​​the U-shaped channel 412.

[0044] Specifically, the U-shaped channel 412 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 43 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 412, respectively. Furthermore, the connection between the micro-channel 43 and the vertical channel 411 and the through hole 413 is rounded to reduce gas flow obstruction.

[0045] When the atomizer is placed upright or horizontally, after the e-liquid in the main reservoir 80 enters the vertical channel 411 through the liquid passage, due to the 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 43 generates a large flow resistance. Under the action of pressure difference, the e-liquid tends to flow through the U-shaped channel 412, which has a wider and deeper groove, and slowly permeates through the U-shaped channel 412 to the through hole 413, and finally enters the oil storage component 60 of the secondary reservoir 90. The e-liquid passing through the micro-groove 43 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 412.

[0046] When the atomizer is inverted, the expanding gas enters the vertical channel 411. 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 43 and flow directly to the through hole 413 with low flow resistance, entering the secondary oil storage chamber 90. At this time, the micro-groove 43 becomes the main path for gas depressurization, and the remaining small amount of gas is discharged along the U-shaped channel 412. The dual paths work together to achieve rapid depressurization.

[0047] In other words, through differentiated size design, the viscosity difference between e-liquid and gas is utilized to achieve "adaptive flow distribution." E-liquid, due to its high viscosity, naturally flows through the low-resistance U-shaped channel 412, ensuring stable wicking. Gas, with its low viscosity, can be quickly discharged through the high-resistance micro-groove 43, 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 43 when the device is inverted allows expanding gas to be quickly discharged without accumulating in the main oil reservoir 80, far below the pressure threshold for e-liquid leakage. This enhances the reliability of all-position leak prevention, eliminating concerns about leakage when the device is in a pocket or stored upside down.

[0048] See Figure 4 As shown, in one embodiment, the bottom of the exhaust channel 42 is provided with a rectangular opening 421 communicating with the secondary oil storage chamber 90, 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 412.

[0049] 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 auxiliary oil storage chamber 90. 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 412, connecting with it to form an auxiliary flow channel of "exhaust channel 42 → opening groove 422 → U-shaped channel 412 → auxiliary oil storage chamber 90".

[0050] When a user inhales from the atomizer, the heating wire of the atomizer core assembly 70 heats the e-liquid to produce vapor. The e-liquid in the secondary reservoir 90 is continuously consumed, and the e-liquid in the main reservoir 80 is replenished to the secondary reservoir 90 through the liquid passage 41. At this time, a slight negative pressure is formed in the main reservoir 80 due to the reduction of e-liquid. Under the action of pressure difference, outside air enters the secondary reservoir 90 through the top of the e-liquid 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 main reservoir 80, filling the space created by the consumption of e-liquid, so that the pressure in the main reservoir 80 always maintains a dynamic balance with the outside.

[0051] When outside air enters the main oil storage chamber 80 through the exhaust channel 42, the e-liquid can flow into the exhaust channel 42 through the open groove 422 and the U-shaped channel 412 since the open groove 422 of the exhaust channel 42 is connected to the open groove 422. The e-liquid forms a liquid seal layer in the exhaust channel 42, which prevents the main oil storage chamber 80 from directly forming a through channel with the outside, ensuring that the main 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.

[0052] In other embodiments, the opening groove 422 can also be directly connected to the main oil storage chamber 80 through the oil guiding structure, so that the e-liquid can flow into the exhaust channel 42 through the oil guiding structure, and the e-liquid forms a liquid seal layer in the exhaust channel 42.

[0053] See Figure 2 and Figure 3 As shown, in one embodiment, the inner support 40 is further provided with an annular retaining sleeve 44 in the area of ​​the secondary oil storage chamber 90. The annular retaining sleeve 44, together with the bottom seal 20 and the inner wall of the inner support 40, forms an isolation chamber 110. The isolation chamber 110 is connected to the through hole 413 and the secondary oil storage chamber 90.

[0054] Specifically, the isolation chamber 110 is directly connected to the liquid passage 41 (the end point of the U-shaped channel 412) through the through hole 413 on the side wall of the inner support 40; on the other hand, four evenly distributed notches (notch width 1mm) are opened at the upper end of the side wall of the annular sleeve 44, so that the isolation chamber 110 is connected to the auxiliary oil storage chamber 90, forming a liquid passage 41 → through hole 413 → isolation chamber 110 → notch → auxiliary oil storage chamber 90.

[0055] During the depressurization process (such as high temperature, high altitude, or inverted operation), when the expanding gas enters the secondary oil storage chamber 90 through the liquid passage 41 or the exhaust passage 42, it may carry a small amount of e-liquid with it and be squeezed out. This e-liquid carried by the gas first enters the isolation chamber 110. Since the isolation chamber 110 is separated from the main body area of ​​the secondary oil storage chamber 90 by the annular baffle 44, the e-liquid settles and accumulates in the isolation chamber 110 due to gravity, while the gas enters the upper part of the secondary oil storage chamber 90 through the notch at the upper end of the annular baffle 44 and is then discharged outside the atomizing device. The e-liquid accumulated in the isolation chamber 110 will slowly permeate through the gap between the annular baffle 44 and the inner support 40 under the action of its own gravity and concentration difference, or gradually flow back to the main body area of ​​the secondary oil storage chamber 90 through the notch, and be absorbed by the oil storage component 60 and re-participate in the e-liquid supply.

[0056] See Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, in one embodiment, the inner support 40 is provided with a through cavity 45, the bottom of which is connected to the secondary oil storage cavity 90 and the top of which is connected to the top of the oil cup 10.

[0057] Specifically, the inner support 40 has a cylindrical cavity 45 opened along the axial direction, and the inner wall is smoothed to reduce airflow resistance. The bottom of the cavity 45 directly penetrates the lower end face of the inner support 40 and is connected to the central area of ​​the secondary oil storage cavity 90; the top extends to the upper end face of the inner support 40 and is connected to the inner space of the top of the oil cup 10, and finally connects to the outside through the top of the oil cup 10, forming a longitudinal airflow channel of "secondary oil storage cavity 90 → cavity 45 → top of oil cup 10 → outside".

[0058] In other words, the gas entering the secondary oil storage chamber 90 through the exhaust channel 42 and the gas entering through the liquid passage 41, because their density is lower than that of e-liquid, will naturally flow upward to the secondary oil storage chamber 90, enter the through cavity 45, move vertically upward along the through cavity 45, and finally be discharged from the top of the oil cup 10; in addition, the balance air supplied to the secondary oil storage chamber 90 during the vaping process, after completing the pressure replenishment of the main oil storage chamber 80, the excess air can also be discharged through the through cavity 45 to ensure dynamic pressure stability.

[0059] In one embodiment, the atomizing core assembly 70 includes an atomizing tube, an oil guide, and a heating wire. The atomizing tube is located inside the oil reservoir 60 and its top is connected to the through cavity 45. The oil guide is located inside the atomizing tube and has an oil guide port. The oil guide port is used to connect the oil reservoir 60 and the oil guide. The heating wire is located inside the oil guide.

[0060] Specifically, the atomizing tube is made of 304 stainless steel and has a cylindrical hollow structure. Its outer diameter matches the inner size of the oil reservoir 60, and it is embedded in the center of the oil reservoir 60 by interference fit. The top opening of the atomizing tube is aligned and connected with the bottom of the cavity 45 of the inner support 40, forming a smoke flow path of "atomizing tube → cavity 45 → 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. Each set of oil guide ports consists of 2 circular holes (or square holes), and the height of the holes corresponds to the middle area of ​​the oil reservoir 60. 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 atomizer is powered on, the e-liquid absorbed by the e-liquid in the e-liquid storage chamber 90 and the e-liquid in the e-liquid guide on the side wall of the atomizing tube permeates into the e-liquid guide inside the atomizing tube. The e-liquid guide uses its own capillary action to evenly absorb and transport the e-liquid to the heating coil area. After the heating coil is powered on, it quickly heats up to 180-220℃. The area of ​​the e-liquid guide in contact with the heating coil 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 through-cavity 45 connected to the top of the atomizing tube, and then flows along the through-cavity 45 to the mouthpiece at the top of the e-liquid cup 10, and is finally inhaled by the user.

[0062] In one embodiment, a bottom cover 120 is further provided between the bottom seal 20 and the oil cup 10.

[0063] Specifically, the bottom cover 120 is fixed to the lower end of the oil cup 10 using a snap-fit ​​method, which not only supports the bottom seal 20 but also enhances the assembly and sealing performance between the bottom seal 20 and the oil cup 10. During atomizer use, the e-liquid in the secondary oil reservoir 90 and the gas during depressurization may permeate into the connection gap between the inner support 40 and the bottom seal 20. The bottom seal 20, through its own elastic deformation, fills the tiny gap at the connection point, forming a reliable sealing barrier. In addition, the bottom seal 20 also seals the gap between the inner side of the oil cup 10 and the outer side of the inner support 40, preventing e-liquid from overflowing from the main oil reservoir 80, and also seals the isolation chamber 110 and the secondary oil reservoir 90.

[0064] This utility model also discloses an atomizing device, including a main unit 130 and an atomizer as described above, wherein the main unit 130 is used to provide electrical energy to the atomizer.

[0065] Specifically, the atomizer is powered by the main unit 130. When the atomizer is placed vertically, 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 secondary oil storage chamber 90, and finally enters the top of the oil cup 10 and is discharged. When the atomizer is placed vertically upside down, the expanded gas passes through the liquid inlet and liquid channel 41 in sequence into the secondary oil storage chamber 90, and finally enters the top of the oil cup 10 and is discharged. When the atomizer is placed horizontally, part of 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 secondary oil storage chamber 90. The other part of the expanded gas passes through the liquid inlet and liquid channel 41 in sequence into the secondary oil storage chamber 90. Both gas streams finally enter the top of the oil cup 10 and are discharged. In other words... An oil storage component 60 is installed inside the secondary oil storage chamber 90 formed by the inner support 40 and the bottom seal 20. The e-liquid in the main 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 assembly 70 inside, ensuring sufficient and uniform e-liquid supply during atomization. At the same time, by constructing a gas flow path of "main oil storage chamber 80 - exhaust channel 42 / liquid passage 41 - secondary oil storage chamber 90 - top of oil cup 10", the air that expands in the main 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.

[0066] The host 130 uses existing publicly available technology, which will not be elaborated on here.

[0067] 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.
