Description

Technical Field

[0001] This invention relates to the field of atomizing device technology, and more particularly 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. Summary of the Invention

[0005] The purpose of this invention 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:

[0007] In a first aspect, embodiments of the present invention provide an atomizer, comprising: an oil cup, an oil tank bottom cover, an outer support, an inner support, a top seal, an oil storage component, and an atomizing coil assembly. The oil tank bottom cover is connected to the lower inner side of the oil cup, the top seal is disposed on the upper inner side of the oil cup, the lower end of the outer support is connected to the oil tank bottom cover, and the upper end is connected to the top seal. The oil cup, the oil tank bottom cover, the top seal, and the outer support together form an oil storage cavity, which is used to hold e-liquid. The inner support is disposed inside the outer support, the oil storage component is disposed inside the inner support, the atomizing core assembly is disposed inside the oil storage component, the oil tank bottom cover is provided with a liquid passage communicating with the oil storage cavity, the outer support is provided with a liquid passage hole communicating with the liquid passage, the inner support is provided with a liquid inlet channel communicating with the liquid passage hole, and the outer side of the inner support is also provided with an exhaust channel, the top end of the exhaust channel communicating with the top of the top seal and the bottom end communicating with the inner side of the inner support;

[0008] When the air inside the oil storage chamber expands, the expanded gas overflows along the gap between the top seal 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, the liquid passage hole and the liquid inlet channel.

[0009] In one specific embodiment, the oil storage component and the inner wall of the inner support 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.

[0010] In one specific embodiment, the bottom of the top seal abuts against the oil reservoir, and the top seal is provided with an exhaust hole; the expanded gas flows from bottom to top along the exhaust gap, passes through the exhaust hole, enters the top of the oil cup, and is discharged.

[0011] In one specific embodiment, the exhaust channel is Y-shaped, and there are two exhaust channels, which are symmetrically distributed on the outer side wall of the inner support.

[0012] In one specific embodiment, the top end of the inner support has a protrusion extending outward, and the top seal has a corresponding insertion hole for the protrusion.

[0013] In one specific embodiment, the number of liquid passages is four, and they are evenly distributed on the bottom cover of the oil tank.

[0014] In one specific embodiment, a sealing silicone component is further provided between the outer support and the bottom cover of the oil tank, and the sealing silicone component is provided with a liquid guide hole communicating with the liquid passage and the liquid passage hole.

[0015] In one specific embodiment, a sealing ring is also provided between the oil tank bottom cover and the oil cup.

[0016] 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 top of the oil cup. 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.

[0017] The atomizer of this invention has the following advantages compared to the prior art: When the atomizing device is placed vertically, the expanded gas overflows along the gap between the top seal 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 along the liquid passage, liquid passage hole, and liquid inlet 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 gap between the top seal 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 support along the liquid passage, liquid passage hole, and liquid inlet channel. Inside, the two gas paths finally enter the top of the oil cup and exit. In other words, by setting an exhaust channel on the outside of the inner support and constructing a gas flow path of "oil storage chamber - exhaust channel / liquid passage - 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. Regardless of whether the atomizing device is placed vertically, vertically upside down, or horizontally, the expanding gas can be depressurized through the corresponding path (when placed vertically, it enters the exhaust channel through the gap between the top seal and the oil cup; when placed upside down, it passes through the liquid channel - liquid passage hole - liquid inlet channel; when placed horizontally, the two paths run in parallel) to solve the core problem of oil overflow caused by air expansion.

[0018] Secondly, embodiments of the present invention provide an atomizing device, including an atomizer and a main unit as described above, wherein the main unit is used to provide electrical energy to the atomizer.

[0019] The beneficial effects of the atomizing device of the present invention compared with the prior art are as follows: The atomizer is powered by the main unit. When the atomizing device is placed vertically, the expanded gas overflows along the gap between the top seal 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 along the liquid passage, liquid passage hole, and liquid inlet 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 gap between the top seal 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 side of the inner support along the liquid passage, liquid passage hole, and liquid inlet channel. The gas enters the inner side of the inner support through two channels, and finally enters the top of the oil cup and is discharged. In other words, by setting an exhaust channel on the outside of the inner support and constructing a gas flow path of "oil storage chamber - exhaust channel / liquid passage - inner side of inner support - top of 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. Regardless of whether the atomizing device is placed vertically, vertically upside down, or horizontally, the expanded gas can be depressurized through the corresponding path (when placed vertically, it enters the exhaust channel through the gap between the top seal and the oil cup; when placed upside down, it passes through the liquid channel - liquid passage hole - liquid inlet channel; when placed horizontally, the two paths run in parallel) to solve the core problem of oil overflow caused by air expansion.

[0041] See Figures 1 to 12As shown, this invention discloses a specific embodiment of an atomizer, including: an oil cup 10, an oil tank bottom cover 20, an outer support 30, an inner support 40, a top seal 50, an oil storage component 60, and an atomizing core assembly 70. The oil tank bottom cover 20 is connected to the lower inner side of the oil cup 10, and the top seal 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 oil tank bottom cover 20, and the upper end is connected to the top seal 50. The oil cup 10, the oil tank bottom cover 20, the top seal 50, and the outer support 30 enclose an oil storage cavity 80, which is used to hold smoke. 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 oil tank bottom cover 20 is provided with a liquid passage 21 communicating with the oil storage chamber 80, the outer support 30 is provided with a liquid passage hole communicating with the liquid passage 21, the inner support 40 is provided with a liquid inlet channel 41 communicating with the liquid passage hole, and 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 top of the top seal 50, and the lower end is connected to the inner side of the inner support 40;

[0042] When the air inside the oil storage chamber 80 expands, the expanded gas overflows along the gap between the top seal 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 along the liquid passage 21, the liquid passage hole and the liquid inlet channel 41.

[0043] Specifically, the oil cup 10 serves as the outer shell of the atomizer. Its lower inner end is fixed to the oil tank bottom cover 20 via a threaded connection or snap-fit, forming a bottom seal of the oil storage chamber 80. A top seal 50 is embedded in the upper inner side of the oil cup 10. The top seal 50 is made of food-grade silicone, ensuring sealing performance while allowing a small gap between it and the inner wall of the oil cup 10 for gas flow. The outer bracket 30 has a cylindrical structure. Its lower end is sealed to the central protrusion of the oil tank bottom cover 20, and its upper end engages with the inner groove of the top seal 50. The oil cup 10, oil tank bottom cover 20, top seal 50, and outer bracket 30 together form an annular oil storage chamber 80, in which e-liquid is directly filled, achieving a visually appealing display of the e-liquid product. In addition, the inner support 40 is coaxially disposed inside the outer support 30. An exhaust channel 42 is axially formed on the outer wall of the inner support 40. The top end of the exhaust channel 42 is connected to the top of the top seal 50 and communicates with the gap between the top seal 50 and the oil cup 10. The lower end extends through to the inner side of the inner support 40. The oil storage component 60 is made of porous ceramic or oil storage cotton and is sleeved inside the inner support 40 to absorb the e-liquid entering from the liquid inlet channel 41. The atomizing core assembly 70 includes a heating wire and an oil-guiding cotton and is installed inside the oil storage component 60. When the heating wire is energized, it can heat the e-liquid absorbed by the oil-guiding cotton to produce vapor. In addition, the bottom cover 20 of the oil tank has a liquid passage 21. One end of the liquid passage 21 is connected to the oil storage chamber 80, and the other end extends to the outer support 30. The side wall of the outer support 30 has a liquid passage hole corresponding to the position of the liquid passage 21, and the side wall of the inner support 40 has a liquid inlet channel 41 corresponding to the liquid passage hole. The three are connected in sequence to form an e-liquid supply path, ensuring that the e-liquid in the oil storage chamber 80 can enter the oil storage component 60 through this path.

[0044] When the atomizer is placed vertically, the e-liquid in the reservoir 80 concentrates at the bottom due to gravity, creating an air zone at the top. When the ambient temperature rises or the air expands due to high altitude, the expanded gas flows upward, enters the exhaust channel 42 on the outside of the inner support 40 through the reserved gap between the top seal 50 and the oil cup 10, and flows downward along the exhaust channel 42 to the inside of the inner support 40, finally being discharged through the air outlet at the top of the oil cup 10, completing the pressure release.

[0045] When the atomizer is placed vertically upside down, the e-liquid concentrates in the upper part of the reservoir 80, blocking the gap between the top seal 50 and the e-liquid cup 10. At this time, the expanded gas flows downward, passing through the liquid passage 21 of the bottom cover 20, the liquid passage hole of the outer bracket 30, and the liquid inlet channel 41 of the inner bracket 40 into the inner side of the inner bracket 40, and then is discharged through the gas outlet at the top of the e-liquid cup 10, preventing the gas from forcing the e-liquid to leak out from the sealing gap.

[0046] When the atomizer is placed horizontally, the e-liquid is evenly distributed within the reservoir 80, partially obstructing the top gap and the liquid passage 21. Part of the expanded gas enters the exhaust passage 42 through the unobstructed gap between the top seal 50 and the oil cup 10, while the other part enters the inner support 40 via the liquid passage 21-liquid hole-inlet passage 41 path and is discharged through the outlet at the top of the oil cup 10, ensuring pressure relief at any horizontal angle.

[0047] In other words, due to the viscosity of e-liquid, there is strong flow resistance within the microchannel. Air flows much more smoothly than e-liquid through the same microchannel, so the expanded gas will be expelled preferentially. Specifically, by setting an exhaust channel 42 on the outside of the inner support 40 and constructing a gas flow path of "oil reservoir 80 - exhaust channel 42 / liquid passage 21 - inner side of inner support 40 - top of oil cup 10," the air expanding in the oil reservoir 80 due to environmental factors such as high temperature and high altitude can be orderly discharged 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 (when placed vertically, it enters the exhaust channel 42 through the gap between the top seal 50 and the oil cup 10; when placed upside down, it passes through the liquid passage 21 - liquid passage hole - liquid inlet channel 41; when placed horizontally, the two paths run in parallel), thus solving the core problem of oil overflow caused by air expansion. Furthermore, traditional e-liquid products are prone to leakage during transportation (such as high-altitude transport and high-temperature storage) and use (such as in high-temperature summer environments and environmental changes when carried around). This atomizer, however, utilizes a directional pressure relief structure to ensure leakage is prevented under various operating conditions, reducing product contamination from e-liquid leakage and limiting user scenarios, thus increasing consumer satisfaction and trust. Moreover, as a key selling point of e-cigarettes, the leak-proof function of this atomizer, through its reliable leak-proof technology, differentiates it from similar e-liquid products, effectively attracting consumers who value user experience. This, in turn, helps brands increase market share and promotes the large-scale promotion of e-liquid products.

[0048] See Figures 9 to 12 As shown, in one embodiment, the oil storage component 60 and the inner wall of the inner support 40 form an exhaust gap; 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.

[0049] Specifically, in the assembly structure of the oil reservoir 60 and the inner support 40, the oil reservoir 60 adopts a design where the outer peripheral wall of the oil reservoir 60 is not tightly fitted to the inner wall of the inner support 40 (i.e., the currently used tight-fitting design, i.e., zero-gap design; when the oil reservoir 60 is made of a loose material (such as oil-absorbing cotton), due to the loose nature of the material, gas can still easily pass through the contact surface between the oil reservoir 60 and the inner support 40 after expansion. The interference fit design between the oil reservoir 60 and the inner wall of the inner support 40 also satisfies the venting function, and the range can be given to -1 to 1 mm), so that an annular venting gap is formed between the two. The oil reservoir 60 is made of cylindrical porous ceramic material, and its outer diameter is smaller than that of the inner support 40. During assembly, the oil reservoir 60 is coaxially sleeved on the inner side of the inner support 40. It is fixed by the positioning protrusions at the upper and lower ends cooperating with the limiting grooves of the inner support 40, ensuring that a uniform exhaust gap with a width of -0.2 to 1 mm is formed between the oil reservoir 60 and the inner wall of the inner support 40 (for example, for ceramic oil reservoirs 60, due to the irregular arrangement of particles, the ceramic oil reservoir 60 and the inner side of the inner support 40 are not completely sealed when there is no gap, and gas can also be discharged normally). This gap runs through the inner support 40 axially, with the lower end connected to the liquid inlet channel 41 of the inner support 40, and the upper end extending to the top of the inner support 40 and connecting with the venting channel at the top of the oil cup 10.

[0050] When the expanded gas enters the inner side of the inner support 40 through the exhaust channel 42 or the liquid inlet channel 21-liquid outlet channel 41, it first enters the space between the bottom of the inner support 40 and the lower end of the oil reservoir 60, and then flows upward along the exhaust gap formed by 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, and finally be 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.

[0051] In other words, the exhaust gap design provides a dedicated upward channel for the expanding gas inside the inner support 40, resulting in low resistance and a direct path for gas flow along the annular gap. Compared to the undirected space inside the inner support 40, the annular exhaust gap guides the gas to flow quickly from bottom to top and be discharged, significantly improving the efficiency of pressure release in the oil storage chamber 80 and further reducing the risk of leakage due to untimely pressure release. Furthermore, the exhaust gap is clearly separated from the e-liquid adsorption area of ​​the oil storage component 60. When the expanding gas flows within the gap, it will not impact or disturb the e-liquid adsorbed in the oil storage component 60, preventing e-liquid from being carried into the exhaust path by the airflow, thus avoiding fluctuations in vapor production or waste. Simultaneously, the annular gap design evenly distributes the gas flow pressure, preventing excessive local airflow from damaging the oil storage component 60 and ensuring the stable operation of its oil guiding and storage functions.

[0052] See Figure 2 , Figures 9 to 12 As shown, in one embodiment, the bottom of the top seal 50 abuts against the oil reservoir 60, and the top seal 50 is provided with an exhaust hole; the expanded gas flows from bottom to top along the exhaust gap, passes through the exhaust hole and enters the top of the oil cup 10 and is discharged.

[0053] Specifically, in the assembly structure of the top seal 50 and the oil reservoir 60, the top seal 50 is made of silicone material in the shape of a disc. Its lower surface is designed as a flat abutment surface, which completely fits against the top surface of the oil reservoir 60, forming an axial limit while blocking the direct communication between the top of the oil reservoir 60 and the top of the inner support 40. The central area of ​​the top seal 50 has an axially extending vent hole that penetrates the upper and lower surfaces, or a notch is opened near the central area at the bottom of the top seal 50 to form a vent hole. The number of vent holes is 1-10 and they are evenly distributed in a ring. The vent holes communicate with the vent gap formed by the inner walls of the oil reservoir 60 and the inner support 40, and the upper end communicates with the vent chamber at the top of the oil cup 10.

[0054] When the expanded gas flows upward along the exhaust gap to the top of the oil reservoir 60, the top of the oil reservoir 60 is sealed by the top seal 50, preventing the gas from diffusing radially. Instead, the gas gathers at the junction of the exhaust gap and the top seal 50, then passes through the exhaust hole on the top seal 50 and enters the exhaust chamber at the top of the oil cup 10. Finally, it is discharged to the outside through the mouthpiece or exhaust port at the top of the oil cup 10, completing the pressure release process. Simultaneously, the tight contact between the top seal 50 and the oil reservoir 60 prevents the e-liquid in the oil reservoir 60 from overflowing upwards into the exhaust hole, avoiding waste or affecting the taste due to the e-liquid being discharged with the airflow.

[0055] In other words, by abutting the top seal 50 against the oil reservoir 60 and opening an exhaust port, a unique outlet channel is provided for the rising gas within the exhaust gap, preventing gas from stagnating or spreading disorderly at the top of the oil reservoir 60. After rising along the exhaust gap, the gas can directly enter the top of the oil cup 10 through the exhaust port, resulting in a shorter path and less resistance, further improving the efficiency and accuracy of pressure release. This process eliminates the problem of pressure accumulation in the oil reservoir 80 caused by an unclear exhaust path. Furthermore, the top seal 50 effectively isolates the oil reservoir area from the exhaust area by abutting the oil reservoir 60, preventing e-liquid from entering the exhaust path, while also ensuring smooth gas discharge through the exhaust port, achieving a synergistic function of "sealing and leak prevention" and "exhausting and pressure relief." Compared to structures without a dedicated exhaust port, this design ensures leak prevention while avoiding interference with the e-liquid storage state caused by gas discharge, thus guaranteeing the normal oil guiding and atomization effects of the e-cigarette. Furthermore, the abutment structure of the top seal 50 not only serves to seal and guide exhaust, but also provides axial fixation for the oil reservoir 60, preventing displacement of the oil reservoir 60 due to vibration or changes in posture during atomizer use, thus improving the overall structural stability. Simultaneously, the exhaust port is directly located on the top seal 50, eliminating the need for an additional independent exhaust component. This simplifies the number of parts and assembly processes, reduces production and assembly costs, and facilitates mass production.

[0056] See Figures 5 to 8 As shown, in one embodiment, the exhaust channel 42 is Y-shaped, and there are two exhaust channels 42, which are symmetrically distributed on the outer side wall of the inner support 40.

[0057] Specifically, in the design of the outer wall of the inner support 40, two Y-shaped exhaust channels 42 are centrally symmetrically distributed, located on both sides of the outer wall with the central axis of the inner support 40 as the symmetry reference. Each Y-shaped exhaust channel 42 consists of one vertical main channel and two oblique branch channels. The vertical main channel is opened along the axial direction of the inner support 40, with its bottom end penetrating to the inner side of the inner support 40 and communicating with the exhaust gap formed by the oil reservoir 60 and the inner wall of the inner support 40. Its top end branches out to both sides of the outer wall of the inner support 40 to form two oblique branch channels. The angle between the oblique branch channels and the vertical main channel is 45 degrees to 60 degrees, and the end of the oblique branch channels extends to communicate with the top of the top seal 50.

[0058] When the air in the oil storage chamber 80 expands, the gas enters the oblique branch channel of the Y-shaped exhaust channel 42 through the gap between the top seal 50 and the oil cup 10, then merges into the vertical main channel, and quickly enters the exhaust gap inside the inner support 40 along the vertical main channel, and finally exits through the exhaust hole of the top seal 50.

[0059] See Figures 5 to 6As shown, in one embodiment, the top end of the inner support 40 extends outward with a protrusion 43, and the top seal 50 is provided with a insertion hole corresponding to the protrusion 43.

[0060] Specifically, in the top structure design of the inner support 40, 2-4 protrusions 43 extend evenly outward along its outer peripheral wall. Each protrusion 43 has a rectangular block structure, and its outer side wall is curved, maintaining the same curvature as the outer peripheral wall of the inner support 40. The top seal 50 is made of silicone, and its inner sidewall has insertion holes corresponding to the positions of the protrusions 43. These insertion holes are rectangular and match the shape of the protrusions 43, with the depth matching the height of the protrusions 43 to ensure an interference fit after insertion. During assembly, the protrusions 43 at the top of the inner support 40 are aligned with the insertion holes of the top seal 50, and axial pressure is applied to insert the protrusions 43 into the insertion holes. The interference fit achieves a fixed connection between the inner support 40 and the top seal 50, while the protrusions 43 fit tightly against the sidewall of the insertion hole, forming a radial seal.

[0061] See Figures 3 to 4 As shown, in one embodiment, there are four liquid passages 21, which are evenly distributed on the bottom cover 20 of the oil tank.

[0062] Specifically, in the structural design of the oil tank bottom cover 20, four liquid passages 21 are evenly distributed in a ring around the central axis of the oil tank bottom cover 20. One end of the liquid passage 21 opens on the upper surface of the oil tank bottom cover 20 facing the oil storage chamber 80, and the edge of the opening is chamfered. The main purpose is to seal the liquid passage 21 of the oil tank bottom cover 20. A sealing element is designed on the outside of this position. The material of the sealing element can be metal, plastic, silicone, or other sealing materials. The chamfer facilitates the assembly of the sealing element. The other end opens through to the lower surface of the oil tank bottom cover 20 facing the outer support 30 and corresponds to the liquid passage hole opened on the side wall of the outer support 30. To ensure smooth flow of e-liquid and avoid leakage, the inner wall of the liquid passage 21 is smoothed. During the e-liquid supply process, the e-liquid in the oil storage chamber 80 flows synchronously into the liquid passage hole of the outer bracket 30 through four evenly distributed liquid passages 21, and then enters the oil storage component 60 through the liquid inlet channel 41 of the inner bracket 40; when the atomizer is placed vertically upside down and the expanding gas needs to be depressurized through the liquid passage 21, the gas can also be quickly diverted through these four liquid passages into the subsequent path.

[0063] See Figures 2 to 3 As shown, in one embodiment, a sealing silicone component 90 is provided between the outer support 30 and the oil tank bottom cover 20. The sealing silicone component 90 is provided with a liquid guide hole that communicates with the liquid passage 21 and the liquid passage hole.

[0064] Specifically, an annular sealing silicone element 90 is added between the assembly interface of the oil tank bottom cover 20 and the outer bracket 30. This sealing silicone element 90 is made of food-grade silicone, and its shape matches the contour of the end face of the oil tank bottom cover 20 facing the upper bracket. Corresponding to the four evenly distributed liquid passages 21 on the oil tank bottom cover 20, the sealing silicone element 90 has four circular liquid guiding holes. The diameter of the liquid guiding holes is the same as the diameter of the liquid passage holes, and the axis of the liquid guiding holes is completely coincident with the axis of the liquid passage holes, ensuring precise alignment to form a continuous e-liquid / gas flow path. Furthermore, both the upper and lower surfaces of the sealing silicone element 90 are designed as flat sealing surfaces, and a raised sealing ring is provided around the outer periphery of the liquid guiding holes.

[0065] In other words, the sealing silicone component 90 forms a surface seal with the oil tank bottom cover 20 and the outer bracket 30 through the sealing rings on its upper and lower surfaces. At the same time, the liquid guide hole forms an orifice seal with the liquid passage 21 and the port of the liquid passage hole, thus constructing a "surface + orifice" dual sealing structure. Compared with the method of sealing only through the gap between the mating parts, this design greatly improves the sealing reliability at the connection between the liquid passage 21 and the liquid passage hole. It can effectively prevent the e-liquid in the oil storage chamber 80 from leaking through the assembly gap between the oil tank bottom cover 20 and the outer bracket 30, and also prevent the expansion gas from escaping from the interface gap during the pressure relief process, which would cause the pressure relief path to fail. In addition, since the sealing silicone part 90 has a certain elastic deformation capability, it can compensate for the machining size error or assembly alignment deviation of the oil tank bottom cover 20 and the outer bracket 30 through its own deformation during the assembly process. This ensures that the liquid guide hole is always precisely aligned with the liquid passage 21 and the liquid passage hole, avoiding narrowing or blockage of the flow channel due to deviation. This not only ensures the smooth supply of e-liquid, but also ensures that the expanding gas can quickly enter the liquid passage hole through the liquid guide hole under the inverted working condition, maintaining the stability of the pressure relief efficiency.

[0066] See Figures 2 to 3 As shown, in one embodiment, a sealing ring is also provided between the oil tank bottom cover 20 and the oil cup 10.

[0067] Specifically, in the assembly structure of the oil tank bottom cover 20 and the oil cup 10, an annular sealing groove is radially formed on the outer peripheral wall of the oil tank bottom cover 20. A nitrile rubber sealing ring is selected, with a circular cross-section and a cross-sectional diameter 0.3-0.5 mm larger than the width of the sealing groove, to ensure that the sealing ring can form an effective pre-compression after installation, thereby improving the sealing effect.

[0068] In other words, the sealing ring fills the assembly gap between the oil tank bottom cover 20 and the oil cup 10 through compression deformation, forming a reliable radial sealing barrier that effectively prevents e-liquid in the oil storage chamber 80 from leaking from the mating point between the oil tank bottom cover 20 and the oil cup 10. Especially when the oil storage chamber 80 generates pressure due to air expansion, the sealing ring can withstand the squeezing of e-liquid under pressure, preventing e-liquid from breaking through the bottom sealing interface and fundamentally eliminating the possibility of bottom leakage.

[0069] See Figures 2 to 3 As shown, 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 storage component 60 and its top is connected to the top of the oil cup 10. 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 storage component 60 and the oil guide. The heating wire is located inside the oil guide.

[0070] Specifically, the atomizing tube is made of food-grade 304 stainless steel and has a cylindrical structure with open ends. Its outer diameter is slightly smaller than the inner diameter of the oil reservoir 60. It is coaxially fitted and fixed inside the oil reservoir 60. Its top end is connected to the air outlet seat at the top of the oil cup 10 via a threaded connection or interference fit, forming the main channel for vapor discharge. Four to six elliptical oil guide ports are evenly distributed axially on the side wall of the atomizing tube to ensure that the e-liquid absorbed by the oil reservoir 60 can enter the interior of the atomizing tube through these ports. The oil guide is made of high-polymer absorbent cotton, cut into a cylindrical shape that fits snugly against the inner wall of the atomizing tube. It is tightly filled inside the atomizing tube, and its outer peripheral wall fits seamlessly against the inner wall of the atomizing tube. When the e-liquid in the oil reservoir 60 comes into contact with the oil guide through the oil guide port, it is quickly absorbed and evenly distributed by the oil guide through capillary action. The heating wire is made of nickel-chromium alloy wire, wound into a spiral structure, and horizontally inserted into the central area of ​​the oil guide. The two ends of the heating wire extend through the insulating fixing base at the bottom of the atomizing tube to the external circuit, and are connected to the power supply through the pins to achieve power heating.

[0071] The present invention also discloses an atomizing device, including an atomizer and a host 100 as described above, wherein the host 100 is used to provide electrical energy to the atomizer.

[0072] Specifically, the main unit 100 provides electrical power to the atomizer. When the atomizer is placed vertically, the expanded gas overflows along the gap between the top seal 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 atomizer is placed vertically upside down, the expanded gas sequentially enters the inner side of the inner support 40 along the liquid passage 21, the liquid passage hole, and the liquid inlet channel 41, 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 along the gap between the top seal 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 sequentially enters the inner support 40 along the liquid passage 21, the liquid passage hole, and the liquid inlet channel 41. Inside the inner side, the two gas paths finally enter the top of the oil cup 10 and are discharged. In other words, by setting an exhaust channel 42 on the outside of the inner support 40 and constructing a gas flow path of "oil storage chamber 80 - exhaust channel 42 / liquid passage 21 - 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 (when placed vertically, it enters the exhaust channel 42 through the gap between the top seal 50 and the oil cup 10; when placed upside down, it passes through the liquid passage 21 - liquid passage hole - liquid inlet channel 41; when placed horizontally, the two paths run in parallel) to solve the core problem of oil overflow caused by air expansion.

[0073] The host 100 uses existing publicly available technology, which will not be elaborated on here.

[0074] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present technical solution are within the protection scope of the present invention.
