Description

Technical Field

[0001] This invention relates to the field of atomizer technology, and more specifically to an electronic atomizing device. Background Technology

[0002] With technological advancements and evolving market demands in the electronic atomization device industry, major products have gradually shifted from traditional oil-retaining cotton products to clear oil-based products. However, existing clear oil-based electronic atomization products generally suffer from significant leakage issues. This problem occurs frequently during environmental changes, product transportation, and actual consumer use, severely impacting the user experience, reducing product satisfaction, and directly negatively affecting brand reputation and overall market sales.

[0003] The leakage problem of the aerosol generation matrix in electronic atomizing devices is mainly driven by environmental factors. For example, in high-temperature environments, the air and aerosol generation matrix inside the fuel tank expand synchronously, causing a sharp increase in internal pressure. Excessive pressure can force the aerosol generation matrix out of the fuel tank, leading to leakage. Similarly, in high-altitude or high-flying environments, the significantly reduced external air pressure creates a substantial pressure difference between the inside and outside of the fuel tank. The relatively high air pressure inside the fuel tank pushes the aerosol generation matrix out of the tank, causing leakage. Therefore, the core cause of leakage in open-oil products is the expansion of the aerosol generation matrix and air inside the fuel tank. The pressure imbalance caused by air expansion is the primary factor leading to the overflow of the aerosol generation matrix. To address this leakage problem, existing electronic atomizing devices lack a pressure balancing mechanism adapted to the structural characteristics of open-oil products. They cannot quickly respond to pressure changes caused by air expansion within the fuel tank and struggle to achieve comprehensive leak prevention under different placement conditions (upright, upside down, and flat).

[0004] Therefore, there is an urgent need for an electronic atomization device that can optimize the pressure balance inside and outside the oil tank and improve the leakage problem of Mingyou series products. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an electronic atomizing device to solve the technical problem of easy leakage in existing open-oil electronic atomizing devices.

In the inverted position, the gas expanded in the main oil chamber enters the auxiliary oil chamber and the connecting chamber through the liquid guiding channel. In the horizontal position, the gas expanded in the main oil chamber enters the auxiliary oil chamber and the connecting chamber through the exhaust channel and the liquid guiding channel. The expanded gas entering the auxiliary oil chamber is discharged outside the reaction zone through the gas guiding channel and / or the gas outlet channel, and the expanded gas entering the connecting chamber is discharged outside the reaction zone through the gas guiding channel and / or the gas outlet channel.

[0007] In one embodiment, the connecting cavity is disposed on the bottom cover; or, the connecting cavity is disposed on the air outlet; or, the bottom cover is provided with a first cavity, the base protrudes a connecting cylinder toward the first cavity, the connecting cylinder is provided with a second cavity, and the first cavity and the second cavity communicate to form the connecting cavity.

[0008] In one embodiment, the bottom cover is provided with a first through hole, one end of which is connected to the exhaust channel and the other end is connected to the communicating cavity.

[0009] In one embodiment, the liquid guiding channel includes a second through hole and a third through hole; both the second through hole and the third through hole are disposed on the bottom cover and extend inward from the bottom cover; the inner end of the second through hole is connected to the communicating cavity, and the other end is connected to the main oil cavity; the inner end of the third through hole is connected to the auxiliary oil cavity, and the other end is connected to the main oil cavity.

[0010] In one embodiment, the liquid guiding channel includes: a liquid lowering channel; there is a gap between the third through hole and the inlet section of the liquid lowering channel, one end of the liquid lowering channel is connected to the main oil chamber, and the other end extends in a roundabout manner to the third through hole and / or the second through hole.

[0011] In one embodiment, the liquid guiding channel includes a through groove; the two ends of the through groove are respectively connected to the main oil cavity and the third through hole, and the cross-sectional area of ​​the through groove is smaller than the cross-sectional area of ​​the liquid lowering channel.

[0012] In one embodiment, the two ends of the through groove are respectively connected to the inlet section of the liquid discharge channel and the third through hole.

[0013] In one embodiment, an oil collecting chamber is formed between the bottom cover and the base, and the oil collecting chamber is sequentially connected to the auxiliary oil chamber, the atomizing core assembly, and the air outlet; the connecting chamber is connected to the oil collecting chamber, and the connecting chamber is connected to the auxiliary oil chamber through the oil collecting chamber; the oil collecting chamber is connected to the air guiding channel, and the expanding gas entering the connecting chamber is discharged through the oil collecting chamber and / or the air guiding channel and / or the air outlet channel.

[0016] The beneficial effects of this invention compared to existing technologies are as follows: By setting up exhaust channels and liquid guiding channels, the expansion gas in the main oil chamber, due to the high viscosity of the aerosol matrix, will be discharged preferentially over the matrix. The gas duct seal at the end of the exhaust channel can always maintain a negative pressure state in the main oil chamber, further preventing matrix leakage. Therefore, when placed upright, the expansion gas enters the connecting chamber through the exhaust channel of the outlet cylinder, and is then discharged through the gap between the gas duct seal and the inner wall of the connecting chamber. When placed upside down, the liquid guiding channel switches to a pressure relief channel, and the gas enters the connecting chamber and the auxiliary oil chamber through the liquid guiding channel before being discharged to the outside. When placed horizontally, the exhaust channel and the liquid lowering channel work together to rapidly depressurize through dual paths, ensuring that the pressure inside and outside the oil tank remains balanced. Therefore, this invention improves the leakage problem in the process of environmental changes, product transportation, and use of the Mingyou series, achieving leak prevention in all scenarios of upright, upside down, and horizontal placement, significantly improving the user experience and strengthening product competitiveness.

[0023] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0024] Example 1 See Figures 1-9 As shown, this embodiment discloses an electronic atomizing device, which includes a housing 1 with a mouthpiece 11 at the upper end. The housing 1 contains an exhaust support 2, an atomizing core assembly 3, and a base 4. The base 4 is connected to the inner wall of the housing 1, and a reaction zone is formed between the base 4 and the mouthpiece 11. The exhaust support 2 has a bottom cover 222 and an air outlet 221. The bottom cover 222 covers the side of the base 4 near the mouthpiece 11, and the air outlet 221 extends from the bottom cover 222 to communicate with the mouthpiece 11. An air outlet is provided through the bottom cover 222 and the air outlet 221. Channel 23; Atomizing core assembly 3 is disposed within air outlet channel 23; A main oil chamber 5a is provided between the bottom cover 222, air outlet 221 and housing 1, and a secondary oil chamber 5c is provided within the bottom cover 222, the secondary oil chamber 5c being connected to the air outlet channel 23 and atomizing core assembly 3; The air outlet 221 is provided with an exhaust channel 2211, and a connecting cavity 2221 is provided between the exhaust bracket 2 and the base 4, one end of the exhaust channel 2211 being connected to the main oil chamber 5a, and the other end extending to be connected to the connecting cavity 2221, the secondary oil chamber 5c being connected to the connecting cavity 2221. The connecting cavity 2221 is equipped with a gas passage seal 2222; the connecting cavity 2221 is connected to the gas outlet channel 23, and / or, the base 4 is equipped with a gas guide channel 41 extending outside the reaction zone, and the connecting cavity 2221 is connected to the gas guide channel 41; the bottom cover 222 is equipped with a liquid guide channel 2223, one end of the liquid guide channel 2223 is connected to the main oil chamber 5a, and the other end is connected to the auxiliary oil chamber 5c and the connecting cavity 2221 respectively; wherein, in the upright position, the gas after expansion in the main oil chamber 5a enters the connecting cavity 2221 through the exhaust channel 2211. In the inverted state, the gas expanded in the main oil chamber 5a enters the auxiliary oil chamber 5c and the connecting chamber 2221 through the liquid guiding channel 2223. In the horizontal state, the gas expanded in the main oil chamber 5a enters the auxiliary oil chamber 5c and the connecting chamber 2221 through the exhaust channel 2211 and the liquid guiding channel 2223. The expanded gas entering the auxiliary oil chamber 5c is discharged from the reaction zone through the gas guiding channel 41 and / or the gas outlet channel 23. The expanded gas entering the connecting chamber 2221 is discharged from the reaction zone through the gas guiding channel 41 and / or the gas outlet channel 23.

[0025] Understandably, the secondary oil chamber 5c can directly provide the aerosol generation matrix to the atomizing core assembly 3 for atomization. The aerosol generated by atomization is discharged through the air outlet channel 23 for the user to inhale. In specific implementation, the secondary oil chamber 5c is filled with an oil storage component, which is the medium for adsorbing the aerosol generation matrix, such as oil storage cotton. The expanding gas can leave the secondary oil chamber 5c through the gap between the oil storage component and the bottom cover 221 or the pores of the oil storage component itself, and enter the air outlet channel 23 and / or the air guide channel 41. After the aerosol generation matrix enters the secondary oil chamber 5c, it is quickly adsorbed and evenly distributed by the oil storage component through capillary action, and then continuously and stably conducted to the atomizing core assembly 3 in close contact with it.

[0026] When environmental factors, such as high temperature and high altitude, cause the air and aerosol-generating matrix inside the main oil chamber 5a to expand, the expanded gas will preferentially enter the preset channel because the aerosol-generating matrix has high viscosity and much lower fluidity than gas. Specifically, see... Figures 4-6 As shown, when the device is placed upright, i.e., with the suction nozzle 11 facing upwards or during use, the liquid guiding channel 2223 extends downwards from the upper end of the base cover 222. The aerosol generating matrix in the main oil chamber 5a flows naturally downwards through the liquid guiding channel 2223 to enter the connecting chamber 2221, allowing the airway seal 2222 to contact the aerosol generating matrix and remain constantly wetted. This wets the airway seal 2222 to seal the exhaust channel 2211 and maintains a certain negative pressure in the main oil chamber 5a, preventing the aerosol generating matrix from overflowing to the outside. The exhaust channel 2211 is connected to the exhaust pipe 2. The upper part of 21 extends downwards, and the upper end of the exhaust channel 2211 is located above the liquid level in the main oil chamber 5a. The expanded gas enters the exhaust channel 2211 of the exhaust cylinder 221 from the main oil chamber 5a, and is discharged downwards along the channel to the connecting chamber 2221. Then, it flows through the gap between the connecting chamber 2221 and the air passage seal 2222 into the guide air channel 41 and / or into the exhaust channel 23. The expanded gas flowing into the guide air channel 41 is directly discharged from the guide air channel 41 to below the base 4, and the expanded gas flowing into the exhaust channel 23 is directly discharged from the exhaust cylinder 221 and the suction nozzle 11. See also Figures 7-8 As shown, when the device is inverted, i.e., when the nozzle 11 is placed downwards or during use, the liquid guiding channel 2223 is located above the liquid surface of the main oil chamber 5a. The expanding gas enters the liquid guiding channel 2223 of the base cover 222 from the main oil chamber 5a and is diverted. Part of it flows through the gap between the connecting cavity 2221 and the airway seal 2222 and is discharged through the air guiding channel 41 and / or the air outlet channel 23. The other part flows to the auxiliary oil chamber 5c. The expanding gas entering the auxiliary oil chamber 5c can be discharged through the atomizing core assembly 3 and the air outlet cylinder 221 (i.e., the air outlet channel 23), or it can be discharged through the air guiding channel 41. Multiple paths ensure rapid gas extraction; see also... Figure 9 As shown, when the device is laid flat, that is, when the shell 1 is placed horizontally or nearly horizontally, the expanding gas enters the connecting cavity 2221 through the exhaust channel 2211, and then enters the auxiliary oil cavity 5c and the connecting cavity 2221 through the liquid guiding channel 2223, and is then discharged outside the reaction zone through the gas guiding channel 41 and the gas outlet channel 23.

[0027] See Figure 3 As shown, the connecting cavity 2221 is disposed on the bottom cover 222. The expanded gas flowing along the exhaust channel 2211 can directly enter the connecting cavity 2221 through the exhaust channel 2211, which reduces the processing difficulty of the connecting cavity 2221 and ensures the exhaust efficiency of the expanded gas. It is understood that in other embodiments, the connecting cavity 2221 can also be disposed on the exhaust pipe 221 to shorten the path length of the expanded gas entering the connecting cavity 2221.

[0028] See Figure 2 As shown, in a further embodiment, the exhaust bracket 2 includes: an outer bracket 21 and an inner bracket 22; the inner bracket 22 is fitted over the base 4, and the outer bracket 21 is sleeved over the inner bracket 22; the main oil chamber 5a is located between the outer bracket 21 and the housing 1; the shape of the outer bracket 21 is adapted to the shape of the inner bracket 22, and the outer bracket 21 and the outer side wall of the inner bracket 22 are tightly connected; the exhaust cylinder 221 and the bottom cover 222 are provided on the inner bracket 22; the exhaust channel 2211 and the liquid guiding channel 2223 are provided on the inner bracket 22, and the outer bracket 21 has an exhaust port 211 and a liquid guiding port 212 that correspond to and communicate with the exhaust channel 2211 and the liquid guiding channel 2223, respectively. When the device is placed upright, see [reference needed]. Figure 5 As shown, the exhaust port 211 is located above the liquid level in the main oil chamber 5a. The expanded gas enters the exhaust channel 2211 through this exhaust port 211 and is exhausted according to a predetermined path; see also Figure 7 As shown, when the device is inverted, the liquid guide port 212 is located above the liquid level in the main oil chamber 5a. The expanded gas enters the liquid guide channel 2223 through the liquid guide port 212 and is exhausted along a predetermined path. The sleeve structure of the inner and outer supports forms a directional channel, allowing the gas to be quickly discharged from the main oil chamber 5a through the exhaust port 211 and the liquid guide port 212, effectively maintaining the pressure balance inside and outside the main oil chamber 5a. Furthermore, the exhaust support 2 adopts a split design, which is convenient for processing and assembly. At the same time, the tight connection between the outer support 21 and the inner support 22 ensures that there is no gas leakage and improves the stability of the pressure relief path.

[0029] See Figure 2 and Figure 4 As shown, in a further embodiment, the outer support 21 is fitted to the outer wall of the inner support 22; the exhaust channel 2211 is groove-shaped and located on the outer wall of the air outlet 221 of the inner support 22. The groove-shaped exhaust channel 2211 is located on the outer wall of the air outlet 221 of the inner support 22. After the expanding gas from the main oil chamber 5a enters the groove-shaped exhaust channel 2211, because the groove-shaped exhaust channel 2211 is fitted to the inner wall of the outer support 21, the gas flows smoothly downwards along this trajectory to the connecting cavity 2221. The matching shape of the outer support 21 and the inner support 22 ensures a compact structure, the groove-shaped exhaust channel 2211 is simple and efficient to manufacture, and it also facilitates the layout of other components inside the inner support 22. It is understood that in other embodiments, the outer support 21 and the inner support 22 are an integral structure, which can be made by casting / injection molding process with core mold, or by additive manufacturing process. The air outlet 221 is the part of the integral structure connected to the suction nozzle 11, the bottom cover 222 is the part of the air outlet 221 away from the suction nozzle 11, and the exhaust channel 2211 and the liquid guiding channel 2223 are perforated channels on the integral structure.

[0030] See Figure 2As shown, in a further embodiment, a sealing ring 6a is also provided inside the housing 1. The sealing ring 6a is sealed to the outer wall of the bottom cover 222 of the inner support 22 and the inner wall of the housing 1, and is located at the lower end of the outer support 21. Preferably, the sealing ring 6a is an oil-resistant silicone ring. The sealing ring 6a fills the gap between the bottom cover 222 and the inner wall of the housing 1, forming a sealing barrier. The aerosol generation matrix cannot leak from this gap, further enhancing the leak-proof effect and avoiding secondary leakage problems caused by poor sealing.

[0031] See Figure 4 As shown, in a further embodiment, the bottom cover 222 is provided with a first through hole 2226, which extends downward from the top wall of the bottom cover 222. The upper end of the first through hole 2226 is connected to the exhaust channel 2211, and the other end is connected to the connecting cavity 2221. The expanding gas in the main oil chamber 5a flows downward through the exhaust channel 2211. The first through hole 2226 enables precise docking between the exhaust channel 2211 and the connecting cavity 2221, ensuring smooth communication between the exhaust channel 2211 and the connecting cavity 2221, reducing gas flow resistance, and improving pressure relief efficiency. At the same time, the directional design of the first through hole 2226 prevents gas leakage to other areas. In other embodiments, other flow channel structures or pipe structures can be used to replace the first through hole 2226 according to actual needs to achieve communication between the connecting cavity 2221 and the exhaust channel 2211.

[0032] See Figure 4As shown, in a further embodiment, the liquid guiding channel 2223 includes a second through hole 2227, a third through hole 2228, and a liquid lowering channel 2224 disposed on the bottom cover 222; the second through hole 2227 and the third through hole 2228 both extend inward from the bottom cover 222, the inner end of the second through hole 2227 is connected to the communicating cavity 2221, and the inner end of the third through hole 2228 is connected to the auxiliary oil cavity 5c; there is a gap between the third through hole 2228 and the inlet section of the liquid lowering channel 2224, one end of the liquid lowering channel 2224 is connected to the main oil cavity 5a, and the other end extends in a roundabout manner to the third through hole 2228 and the second through hole 2227. It is understandable that the second through hole 2227 connects the connecting cavity 2221 and the main oil cavity 5a through the liquid lowering channel 2224, so that the aerosol generation matrix in the main oil cavity 5a can be transported to the connecting cavity 2221 through this channel, so that the gas passage seal 2222 is always kept wet, thereby achieving the sealing of the exhaust channel 2211; and it can also assist in pressure relief. The gas after expansion in the main oil cavity 5a flows into the connecting cavity 2221 through the second through hole 2227. The expanded gas entering the connecting cavity 2221 flows directly to the gas outlet channel 23 / gas guide channel 41 through the gap between the gas passage seal 2222 and the inner wall of the connecting cavity 2221, and is then discharged outside the reaction zone through the gas outlet channel 23 / gas guide channel 41. It is also understandable that the third through hole 2228 connects the main oil chamber 5a and the auxiliary oil chamber 5c, which can supply oil to the auxiliary oil chamber 5c to ensure the smooth operation of atomization. It can also serve as a pressure relief channel when the device is placed upside down or flat, ensuring that the device achieves the preset pressure relief effect.

[0033] When the device is upright, the aerosol generation matrix in the main oil chamber 5a first enters the liquid-feeding channel 2224, which is connected to the main oil chamber 5a. It is then transported via the extended path of the liquid-feeding channel 2224 to the second through-hole 2227 and the third through-hole 2228. From there, it flows into the auxiliary oil chamber 5b through the third through-hole 2228, supplying the aerosol generation matrix to the atomizing core assembly 3. Finally, it flows into the connecting chamber 2221 through the second through-hole 2227, wetting the airway seal 2222 and thus blocking the main oil chamber 5a, maintaining a certain negative pressure in the main oil chamber 5a. The extended liquid-feeding channel 2224, with its meandering liquid-guiding structure, prolongs the flow path of the aerosol generation matrix, reduces its flow velocity, and avoids problems such as excessively rapid liquid supply and leakage caused by device shaking or sudden pressure changes. In other embodiments, other flow channel structures or pipe structures can be used to replace the liquid lowering channel 2224 as needed to achieve communication between the third through hole 2228, the second through hole 2227 and the main oil chamber 5a. The alternative design of the liquid lowering channel 2224 greatly improves the design flexibility and scenario adaptability of the liquid guiding channel 2223 structure. A suitable flow channel or pipe structure can be selected according to the actual working conditions such as the internal space of the device, atomization power, and leakage prevention requirements.

[0034] In this embodiment, the second through hole 2227 is provided through the outer wall of the base cover 222. In other embodiments, the second through hole 2227 may be provided through the end face of the base cover 222 facing the main oil chamber 5a. Regardless of whether the second through hole 2227 penetrates from the side wall or the end face of the base cover 222, it constitutes a physical channel connecting the main oil chamber 5a and the connecting cavity 2221, providing a liquid-guiding basis for the humidified gas passage seal 2222, thus keeping the gas passage seal 2222 moist, thereby maintaining the negative pressure state of the main oil chamber 5a, and also ensuring the smooth exhaust of the expanded gas.

[0035] It is understood that, in other embodiments, the channel for conveying the aerosol-generating matrix from the main oil chamber 5a to the connecting chamber 2221 is not limited to the lower liquid channel 2224, but can also be through other flow channel structures (such as... Figure 10 (As shown) Independent of the lower liquid channel 2224, it completes the direct connection between the main oil chamber 5a and the second through hole 2227. Its main function is to ensure that the air passage seal 2222 in the connecting chamber 2221 is always kept moist, ensuring that the exhaust channel 2211 can be sealed, and ensuring that the main oil chamber 5a always maintains a certain negative pressure. Other flow channel structures include, but are not limited to, other channels and pipes provided on the bottom cover 222 or the outer support 21.

[0036] In this embodiment, the third through hole 2228 extends inward from the outer wall of the bottom cover 222. In other embodiments, the third through hole 2228 may extend inward from the end face of the bottom cover 222 toward the main oil chamber 5a. Regardless of whether the third through hole 2228 extends from the side wall or the end face of the bottom cover 222, it constitutes a physical channel connecting the main oil chamber 5a and the auxiliary oil chamber 5b, ensuring both smooth oil supply to the atomizing core assembly 3 and efficient exhaust of the expansion gas.

[0037] In a further embodiment, the liquid discharge channel 2224 is arranged in a circuitous manner, with two liquid discharge branches forming at its end. These two branches connect to the second through-hole 2227 and the third through-hole 2228, respectively. When the device is placed upside down or flat, the expanding gas in the main oil chamber 5a enters the circuitous liquid discharge channel 2224. Due to its high fluidity, the gas quickly splits at the end into the two liquid discharge branches, entering the connecting chamber 2221 through the second through-hole 2227 and being guided to the auxiliary oil chamber 5c through the third through-hole 2228. The two gas paths are discharged synchronously, avoiding congestion in a single branch. The circuitous structure extends the matrix flow path, reducing the risk of matrix leakage when the device is upright. Simultaneously, the dual-branch design improves the gas discharge efficiency when the device is placed upside down or flat, balancing leak prevention and pressure relief performance.

[0038] In a further embodiment, the liquid guiding channel 2223 includes a through groove 2229; the cross-sectional area of ​​the through groove 2229 is smaller than the cross-sectional area of ​​the liquid discharge channel 2224, and the two ends of the through groove 2229 are respectively connected to the inlet section of the liquid discharge channel 2224 and the third through hole 2228. See also Figure 4 As shown, since the cross-sectional area of ​​the through-slot 2229, i.e., its cross-sectional dimensions, is much smaller than that of the liquid-lowering channel 2224, when the device is placed upright, the aerosol generating matrix, due to its high viscosity and extremely high flow resistance, is difficult to pass through the through-slot 2229. At this time, the aerosol generating matrix in the main oil chamber 5a is mainly transported to the auxiliary oil chamber 5c through the liquid-lowering channel 2224 to meet the atomization requirements. When the device is placed upside down or flat, the gas, due to its strong fluidity, can quickly pass through the through-slot 2229 and enter the third through-hole 2228, and then be discharged through the auxiliary oil chamber 5c and the gas outlet channel 23 / gas guide channel 41 connected to the auxiliary oil chamber 5c, achieving rapid exhaust and pressure relief. At the same time, some gas enters the second through-hole 2227 through the liquid-lowering channel 2224, and is introduced into the gas outlet channel 23 / gas guide channel 41 through the gap between the gas passage seal 2222 and the inner wall of the connecting cavity 2221 before being discharged, forming a secondary pressure relief channel. The two branches work together to complete the pressure relief. Highly efficient gas-liquid separation is achieved through channel 2229, ensuring that gas is preferentially discharged and the matrix cannot leak when the device is inverted. This, in conjunction with the secondary pressure relief channel, improves the reliability and speed of pressure relief when the device is inverted. It is understandable that... Figure 10 As shown, in other embodiments, the through groove 2229 can be configured as an independent flow channel or other gap structure that is directly connected to the main oil chamber 5a, depending on actual needs, to replace the scheme in this embodiment where the two ends of the through groove 2229 are respectively connected to the third through hole 2228 and the inlet section of the liquid channel 2224.

[0039] In this embodiment, there are four exhaust channels 2211, which are evenly distributed in the exhaust cylinder 221. The lower ends of every two exhaust channels 2211 converge and connect to the connecting cavity 2221. Specifically, every two exhaust channels 2211 share a first through hole 2226. When the gas in the main oil chamber 5a expands upright, it simultaneously enters the four evenly distributed exhaust channels 2211. Due to the even layout of the exhaust channels 2211, the gas flow distribution is balanced. After every two channels converge, the gas is introduced into the connecting cavity 2221 through a first through hole 2226, avoiding congestion caused by excessive flow in a single channel. The even distribution of multiple exhaust channels 2211 improves gas emission efficiency. The converging design of the exhaust channels 2211 reduces the number of first through holes 2226, simplifying the structure. Simultaneously, the symmetrical layout ensures even force distribution on the exhaust cylinder 221, enhancing structural stability. It is understood that in other embodiments, the number of exhaust channels 2211 can be adjusted to six, eight, etc., according to actual needs, and the convergence method can be changed to each exhaust channel 2211 corresponding to a first through hole 2226, further improving gas flow efficiency.

[0040] In this embodiment, there are four liquid discharge channels 2224, which are evenly distributed on the bottom cover 222. Every two liquid discharge channels 2224 converge and share a second through hole 2227. When the main oil chamber 5a is inverted, the expanding gas enters the four symmetrically distributed liquid discharge channels 2224 evenly. After every two channels converge, the gas is introduced into the connecting cavity 2221 through a second through hole 2227. The uniform layout of the channels ensures that the gas can be quickly accessed from all areas of the main oil chamber 5a, avoiding local gas stagnation, improving the gas discharge efficiency of the liquid discharge channels 2224, and adapting to the gas flow requirements under different placement conditions. The converging design of the liquid discharge channels 2224 simplifies the structure and reduces the processing difficulty. It is understood that in specific implementations, the number of liquid discharge channels 2224 can be changed to two, six, etc., according to actual needs, and the converging method can be changed to each liquid discharge channel 2224 being connected to a separate second through hole 2227 to further optimize the gas flow path.

[0041] See Figure 3 As shown, in a further embodiment, an oil collecting cavity 5b is formed between the bottom cover 222 and the base 4, and the oil collecting cavity 5b is connected to the auxiliary oil cavity 5c. In specific implementation, the oil collecting cavity 5b is filled with oil-absorbing cotton or is a cavity, and the oil-absorbing cotton is a medium for adsorbing the aerosol generating matrix. As an extension or auxiliary cavity of the auxiliary oil cavity 5c, if the aerosol generating matrix accidentally overflows from the auxiliary oil cavity 5c, it can flow into the oil collecting cavity 5b and be absorbed by the oil-absorbing cotton. The oil collecting cavity 5b provides additional containment space for fluid, collects and stores a small amount of aerosol generating matrix that may leak from the auxiliary oil cavity 5c, and prevents it from further leaking to the outside of the device or critical electrical components, thereby improving the leak-proof reliability of the product.

[0042] See Figure 2 and Figure 5 As shown, in a further embodiment, the housing 1 is further provided with a top seal 6b and a top bracket 7; the top seal 6b is located at the upper end of the inner bracket 22 and is sealed to the inner side wall of the housing 1 and the outer side wall of the inner bracket 22; the top bracket 7 is connected to the upper end of the outer bracket 21 and is located at the lower end of the top seal 6b. The top bracket 7, the outer bracket 21, and the housing 1 enclose and form the main oil chamber 5a; the top bracket 7 is provided with a gas delivery channel 71, one end of which is connected to the main oil chamber 5a, and the other end extends to connect with the upper end of the exhaust channel 2211. Preferably, the top seal 6b can be an oil-resistant seal. When the device is inverted, the top seal 6b prevents the aerosol generation matrix from permeating outward, thus strengthening the sealing performance of the top of the main oil chamber 5a; see again Figure 5As shown, when the device is placed upright, the top seal 6b can effectively seal the main oil chamber 5a. On the one hand, it prevents the aerosol matrix in the main oil chamber 5a from leaking out, and on the other hand, it maintains the negative pressure state inside the main oil chamber 5a, ensuring that the matrix in the main oil chamber 5a can be stably transported downwards. At the same time, it ensures that the expanding gas can only flow into the exhaust channel 2211 through the gas delivery channel 71 of the top support 7 and complete the depressurization along the preset path.

[0043] See Figure 2 As shown, in a further embodiment, the base 4 is also provided with a mounting hole 42 communicating with the air outlet channel 23, and the atomizing core assembly 3 is connected to the mounting hole 42. It can be understood that the atomizing core assembly 3 includes: an atomizing core support 31, a heating wire 32, an oil-wicking cotton 33, and a pin fixing member 34; the atomizing core support 31 is hollowed out and passes through the mounting hole 42 and the air outlet channel 23; the heating wire 32 passes through the atomizing core support 31; the oil-wicking cotton 33 is located between the inner sidewall of the atomizing core support 31 and the heating wire 32; and the pin fixing member 34 is connected to the heating wire 32. In a specific implementation, the mounting hole 42 can also allow the atomizing core support 31 to extend below the base 4. Mounting hole 42 provides mounting positioning for atomizing core assembly 3 without changing or affecting the original gas pressure relief path. The gas after expansion in main oil chamber 5a still flows along the preset exhaust channel 2211 and liquid guiding channel 2223, without interfering with the normal operation of the pressure relief structure, ensuring that leak prevention and atomization functions do not conflict with each other.

[0044] See Figure 1 As shown, in a further embodiment, the housing 1 includes an oil cup 12, a grip shell 13, and a bottom cover 14 connected sequentially from top to bottom; the grip shell 13 is open at both ends and has a hollow structure, and the oil cup 12 and the bottom cover 14 are respectively connected to the two ends of the grip shell 13; the suction nozzle 11 is located at the top of the oil cup 12, and the top seal 6b, top bracket 7, exhaust bracket 2, sealing ring 6a, and base 4 are disposed inside the oil cup 12; the oil cup 12, grip shell 13, and bottom cover 14 are sequentially and detachably connected. Preferably, the oil cup 12, grip shell 13, and bottom cover 14 are connected by snap-fit ​​or tightly fitted. The segmented structure of the housing 1 is an internal pressure relief structure, such as an exhaust channel 2211, which provides an independent installation space. When the gas flows in the preset channel, it is not affected by the segmented connection of the housing 1. After being discharged through the pressure relief structure inside the oil cup 12, it can be discharged to the outside through the reserved space of the grip shell 13 and the bottom cover 14 or the suction nozzle 11. Furthermore, the segmented design of the housing 1 enables modular assembly, facilitating the installation and maintenance of internal components. It is understood that in other embodiments, the oil cup 12 and the grip shell 13 may be integrally molded, and / or the grip shell 13 and the bottom cover 14 may be integrally molded to reduce connection gaps.

[0045] See Figures 1-2As shown, in a further embodiment, the housing 1 is further provided with an oil cup seal 6c, which is sealed to the upper end of the base 4 and the inner wall of the oil cup 12. The oil cup seal 6c fills the gap between the upper end of the base 4 and the bottom cover 222, forming a bottom sealing barrier. This allows the small amount of aerosol generation matrix that may be carried out during the depressurization process to be retained in the oil collection chamber 5b as much as possible, preventing the aerosol generation matrix from leaking into other internal areas of the device and protecting the internal components of the device from contamination.

[0046] In a further embodiment, an oil-absorbing element 8 is provided inside the grip shell 13, and the oil-absorbing element 8 is located at the lower end of the base 4. In specific implementation, oil-absorbing cotton can be selected as the oil-absorbing element 8. The oil-absorbing cotton can absorb the small amount of aerosol that may leak and generate a matrix, without hindering the gas discharge. After the gas is discharged through the gas guide channel 41, the oil-absorbing cotton prevents the matrix from flowing into the interior of the grip shell 13 through adsorption, and does not affect the gas flow efficiency.

[0047] In a further embodiment, a battery cell 9 is also provided inside the grip shell 13; the battery cell 9 is electrically connected to the atomizing core assembly 3; a main board 141 is provided on the bottom cover 14, and a bottom seal 6d is sealingly connected between the bottom cover 14 and the grip shell 13; the main board 141 is located below the battery cell 9 and is electrically connected to the battery cell 9. The battery cell 9 is installed inside the grip shell 13, avoiding the core area of ​​the main oil chamber 5a and the pressure relief structure, and the pressure relief path does not interfere with the power supply components. The bottom seal 6d seals the connection gap between the bottom cover 14 and the main board 141, ensuring that a certain pressure difference is formed between the inside of the grip shell 13 and the outside during the inhalation process, thereby enabling the pressure sensor inside the device to start normally and ensuring the stable implementation of the inhalation function of the electronic atomizing device.

[0048] As described above, the electronic atomizing device of this embodiment, by setting an exhaust channel 2211 and a liquid guiding channel 2223, ensures that the expanding gas in the main oil chamber 5a, due to the high viscosity of the aerosol-generated matrix, will be discharged preferentially over the matrix. The air passage seal 2222 at the end of the exhaust channel 2211 can always maintain the negative pressure state of the main oil chamber 5a, further preventing matrix leakage. Thus, when placed upright, the expanding gas enters the connecting chamber 2221 through the exhaust channel 2211 of the air outlet 221, and is then discharged through the gap between the air passage seal 2222 and the inner wall of the connecting chamber 2221. When placed upside down, the liquid guiding channel 2223 switches to a pressure relief air passage, and the gas enters the connecting chamber 2221 and the auxiliary oil chamber 5c through the liquid guiding channel 2223 and is then discharged to the outside. When placed flat, the exhaust channel 2211 and the liquid guiding channel 2223 work together to quickly depressurize through dual paths, ensuring that the pressure inside and outside the oil tank is always balanced. Therefore, this embodiment improves the leakage problem of the Mingyou series during environmental changes, product transportation and use, and achieves leakage prevention in all scenarios such as upright, upside down and flat placement, which significantly improves the user experience and strengthens the product competitiveness.

[0049] Example 2 See Figures 10-13 As shown, this embodiment discloses an electronic atomizing device, which is an improvement on the electronic atomizing device of Embodiment 1. The difference between this embodiment and Embodiment 1 lies in the different liquid guiding channel 2223.

[0050] In this embodiment, the inner end of the second through hole 2227 is connected to the connecting cavity 2221, and the other end is directly connected to the main oil cavity 5a. The humidification of the gas passage seal 2222 and the exhaust of the expanding gas are achieved through a passage independent of the lower liquid passage 2224, which further improves the leakage prevention function of the device.

[0051] Preferably, the third through hole 2228 is directly connected to the main oil chamber 5a through a through groove 2229, that is, the two ends of the through groove 2229 are connected to the main oil chamber 5a and the third through hole 2228 respectively. The through groove 2229 connecting the third through hole 2228 is an independent flow channel or other gap structure, which is directly connected to the main oil chamber 5a. It can also exhaust the expanding gas without passing through the inlet of the liquid discharge channel 2224, thus ensuring the pressure relief effect.

[0052] Example 3 See Figures 11-13 As shown, this embodiment discloses an electronic atomizing device, which is an improvement on the electronic atomizing device of Embodiment 1 or Embodiment 2. The difference between this embodiment and Embodiment 1 or Embodiment 2 is that: the connecting cavity 2221 is formed by the bottom cover 222 and the base 4; while the flow path of the aerosol generation matrix and the exhaust path of the expanding gas are the same as those of Embodiment 1 / Embodiment 2.

[0053] Specifically, the bottom cover 222 is provided with a first cavity 22211, the base 4 is provided with a connecting cylinder 43 protruding towards the first cavity 22211, the connecting cylinder 43 is provided with a second cavity 431, the first cavity 22211 and the second cavity 431 are connected to form a connecting cavity 2221; the exhaust channel 2211 is connected to the first cavity 22211 through the first through hole 2226, the air passage seal 2222 is filled in the second cavity 431, and the air guide channel 41 is connected to the second cavity 431.

[0054] Understandably, in other alternative embodiments, the air passage seal 2222 can be placed in other structures independent of the bottom cover 222 or the base 4, and it is ensured that it is located at the lower end of the exhaust channel 2211 and connected to the main oil chamber 5a, so that the aerosol generation matrix wets the air passage seal 2222, instead of the air passage seal 2222 being located on the bottom cover 222 and the base 4 in this embodiment, thereby achieving the effect of both sealing the exhaust channel 2211 and realizing the pressure relief function.

[0055] In this embodiment, the electronic atomizing device is formed by docking the first cavity 22211 of the bottom cover 222 with the second cavity 431 of the connecting cylinder 43 of the base 4. While fully retaining the original pressure relief and leak-proof effects in all postures (upright, upside down, and flat), the assembly process of the airway seal 2222 is simplified.

[0056] Example 4 See Figures 14-22 As shown, this embodiment discloses an electronic atomizing device, which is an improvement on the electronic atomizing devices of Embodiment 1, Embodiment 2, or Embodiment 3. The difference between this embodiment and the above embodiments is that the expanded gas entering the connecting cavity 2221 is indirectly discharged through the gas guide channel 41 via the oil collecting cavity 5b.

[0057] Specifically, in this embodiment, the oil collecting cavity 5b is formed by the inner support 22 and the base 4, and the oil collecting cavity 5b is connected to the secondary oil cavity 5c. See also Figure 16 and Figure 21 As shown, the side wall of the auxiliary oil chamber 5c is provided with a perforation 2225, and the auxiliary oil chamber 5c is connected to the oil collecting chamber 5b through the perforation 2225. The expanding gas entering the auxiliary oil chamber 5c can enter the oil collecting chamber 5b through the gap between the oil storage component in the auxiliary oil chamber 5c and the inner wall of the auxiliary oil chamber 5c, and be buffered or temporarily stored there. At the same time, the oil collecting chamber 5b can also collect and store the aerosol generation matrix overflowing from the auxiliary oil chamber 5b, further improving the leak-proof effect of the device.

[0058] See Figure 19 As shown, in this embodiment, the oil collecting chamber 5b is connected to the gas outlet channel 23 and the gas guide channel 41, respectively. The upper part of the oil collecting chamber 5b is connected to the gas guide channel 41 and the gas outlet channel 23, so that the gas entering the oil collecting chamber 5b is discharged through the gas guide channel 41 and the gas outlet channel 23. The expanding gas entering the oil collecting chamber 5b gathers upward and flows into the gas guide channel 41, and is directly discharged outside the reaction zone through the gas guide channel 41. This increases the exhaust outlet of the oil collecting chamber 5b, forming an independent and rapid exhaust path, avoiding pressure relief failure due to blockage of a single outlet, and preventing gas from accumulating in the oil collecting chamber 5b and causing pressure rebound, thus improving exhaust efficiency.

[0059] In a further embodiment, the connecting cavity 2221 is connected to the oil collecting cavity 5b, that is, the connecting cavity 2221 is connected to the auxiliary oil cavity 5c through the oil collecting cavity 5b. See also Figures 17-19As shown, when the device is upright, the aerosol generating matrix in the main oil chamber 5a flows naturally down through the liquid guiding channel 2223 into the connecting chamber 2221, causing the gas passage seal 2222 to contact the aerosol generating matrix and remain wet. This wets the gas passage seal 2222 to seal the exhaust channel 2211. The expanded gas enters the exhaust channel 2211 of the outlet cylinder 221 from the main oil chamber 5a, and is discharged downwards along the channel into the connecting chamber 2221, then passes through the connecting chamber 2221. The gas flowing through the gap between 221 and the air passage seal 2222 flows to the oil collecting chamber 5b, and then from the oil collecting chamber 5b to the auxiliary oil chamber 5c. The expanding gas flowing to the auxiliary oil chamber 5c is discharged to the outside through the air outlet passage 23. In addition, the expanding gas entering the connecting chamber 2221 can also pass through the gap between the connecting chamber 2221 and the air passage seal 2222 to the oil collecting chamber 5b, and then from the oil collecting chamber 5b to the air guide passage 41, and is discharged to the bottom of the base 4 through the air guide passage 41; see below. Figures 20-21 As shown, when the device is inverted, the expanding gas enters the liquid guiding channel 2223 of the bottom cover 222 from the main oil chamber 5a and is split. Part of it flows into the oil collecting chamber 5b through the gap between the connecting chamber 2221 and the gas passage seal 2222, and then exits. The other part flows to the auxiliary oil chamber 5c, and enters the oil collecting chamber 5b through the gap between the oil storage component in the auxiliary oil chamber 5c and the inner wall of the auxiliary oil chamber 5c, and then exits. This dual path ensures rapid gas extraction. See also... Figure 22 As shown, when the device is laid flat, the expanded gas is discharged through the exhaust channel 2211, the connecting chamber 2221, and the oil collecting chamber 5b, and then through the liquid guiding channel 2223, the connecting chamber 2221 / auxiliary oil chamber 5c, and the oil collecting chamber 5b.

[0060] As described above, the expanding gas entering the oil collecting chamber 5b can either quickly flow into the exhaust channel 23 and then be discharged towards the suction nozzle 11, or it can flow into the guide channel 41 and then be discharged downwards towards the base 4, preventing gas from accumulating in the oil collecting chamber 5b and causing a pressure rise. The connection design between the exhaust channel 23, the guide channel 41, and the oil collecting chamber 5b provides a rapid discharge path for the gas in the oil collecting chamber 5b, preventing gas stagnation and pressure rise in the oil collecting chamber 5b, and further ensuring the pressure balance inside and outside the oil tank.

[0061] The above examples are merely illustrative of the technical content of the present invention to facilitate easier understanding by the reader, but do not imply that the implementation of the present invention is limited to these examples.
