Description

Technical Field

[0001] This disclosure relates to the technical field of atomizing devices, and in particular to an inlet partition structure and an aerosol generating device. Background Technology

[0002] The removable oil bottle and atomizing component of the aerosol generator provide users with convenient oil replenishment. Oil enters through the feed port on the aerosol generator and comes into contact with the internal structure of the atomizing component to achieve the atomization process.

[0003] The oil itself has a certain degree of surface tension, which makes it easy for the oil to form a laminar flow state during the flow process. In the laminar flow state, the relative movement between oil molecules is more orderly, the flow resistance increases significantly, and the oil is difficult to fill the oil tank in the atomizing component quickly and fully. The slow filling of oil will seriously restrict the atomization response speed, thereby reducing the working efficiency of the entire aerosol generator.

[0004] When the oil flows directly into the aerosol generator from the oil inlet and comes into contact with the atomizing components, the lack of an effective flow guidance and buffering mechanism causes the oil to directly and rapidly impact the oil inlet, making the oil flow extremely unstable. This leads to significant oil supply fluctuations, which not only interfere with the normal operation of the atomizing components and cause unstable oil intake, but may also damage the internal components of the aerosol generator over a long period of time.

[0005] For example, an atomizer disclosed in prior art CN202420953565.0 uses an interconnected oil passage and mounting hole on the mounting base, with the oil bottle inverted and installed in the mounting hole. The first oil inlet of the cartridge shell is connected to the oil outlet of the oil passage, allowing the e-liquid in the bottle to flow directly out of the bottle under gravity. The e-liquid then flows through the oil passage and then from the first oil inlet to the oil reservoir. The e-liquid in the reservoir then enters the atomizing assembly and is heated and atomized. While this design connects the first oil inlet of the cartridge shell to the oil outlet of the oil passage, allowing the e-liquid to flow directly out of the bottle under gravity, the surface tension of the e-liquid causes significant flow resistance, resulting in a slow entry speed into the first oil inlet. This restricts the atomization response speed and reduces the overall efficiency of the aerosol generator.

[0006] For example, prior art document CN202420113884.0 discloses a pressable e-cigarette cartridge structure and an electronic cigarette, including a cartridge body and an e-cigarette bottle. The cartridge body has an e-cigarette chamber inside that communicates with the e-cigarette bottle connection port. The upper part of the other end of the cartridge body is also provided with a press-sealing mechanism that can close the e-cigarette bottle connection port. The press-sealing mechanism includes a sealing sheet, a return spring and a button. The sealing sheet is placed inside the e-cigarette chamber and covers the upper end of the e-cigarette bottle connection port. The upper end of the sealing sheet is provided with a lifting rod that can pass through the upper end of the cartridge body. The return spring is sleeved on the lifting rod and placed between the sealing sheet and the upper wall of the e-cigarette chamber. The e-cigarette bottle has a bottle mouth that is detachably connected to the e-cigarette bottle connection port. This solution uses a press-to-seal mechanism at the oil bottle connection port on the cartridge body to control the connection between the oil storage bottle and the oil tank. The oil storage bottle and the oil bottle connection port are detachable. However, the oil enters the oil tank directly through the circular connection port. Due to the lack of an effective flow guidance and buffering mechanism, the oil flow is extremely unstable, which leads to large fluctuations in oil supply. The oil tank is easily filled directly, and the amount of oil entering the tank cannot be effectively controlled. Utility Model Content

[0007] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide an inlet partition structure and aerosol generator that improves flow efficiency and buffers oil.

[0008] The purpose of this disclosure is achieved through the following technical solution:

[0009] A feed inlet partition structure includes an atomizing component and an atomizing chamber assembly. The atomizing component is used to atomize oil. The atomizing chamber assembly includes an atomizing shell, a first support, a second support, and an oil sealing element. An atomizing oil chamber is formed between the atomizing shell and the first support. The atomizing component is installed in the atomizing oil chamber. The first support has a connecting hole. A pre-inlet oil chamber is formed between the first support and the second support, communicating with the connecting hole. The connecting hole communicates with the atomizing oil chamber. The oil sealing element passes through the atomizing shell, and one end of the oil sealing element is movably installed in the connecting hole.

[0010] The second bracket has a connecting part protruding from one end opposite to the first bracket. The connecting part has a connecting groove, and an oil inlet column protrudes from the connecting groove. The oil inlet column has an oil inlet hole, which is connected to the pre-oil inlet chamber. At least two partition plates protrude from the inner wall of the oil inlet hole. The two partition plates are arranged opposite to each other and divide the oil inlet hole into two connected oil inlet channels. The two oil inlet channels are connected along the extension direction of the partition plates.

[0011] In one embodiment, wedge-shaped grooves are respectively formed on both sides of the oil inlet column in the circumferential direction, and the wedge-shaped grooves are connected to the oil inlet hole.

[0012] In one embodiment, each of the wedge-shaped grooves is formed with a first inclined surface and a second inclined surface, the first inclined surface and the second inclined surface forming a first included angle.

[0013] In one embodiment, each of the partition pieces is formed with a third inclined surface and a fourth inclined surface, the third inclined surface and the fourth inclined surface together forming a second included angle.

[0014] In one embodiment, the first included angle is set to correspond to the second included angle.

[0015] In one embodiment, the cross-section of the connecting hole is an elongated elliptical structure with semicircles at both ends, and the outer edge of the sealing element corresponds to the connecting hole.

[0016] In one embodiment, the oil inlet hole and the connecting hole are eccentrically positioned.

[0017] In one embodiment, the end of the oil inlet column opposite to the second bracket is flush with the connecting portion.

[0018] In one embodiment, the first support has a first pre-storage slot on the side away from the atomizing housing, and the second support has a second pre-storage slot on the side away from the connecting slot. The first pre-storage slot and the second pre-storage slot together form the pre-oil inlet chamber.

[0019] An aerosol generating device includes an oil bottle, an atomizing base, and an inlet partition structure as described in any of the above embodiments. The oil bottle is connected to the oil inlet, the atomizing base has a receiving groove, and the oil bottle is installed in the receiving groove.

[0020] Compared with the prior art, this disclosure has at least the following advantages:

[0021] The aforementioned feed inlet partition structure divides the oil inlet into two parallel inlet channels when the oil enters the inlet hole under gravity. The partition breaks the surface tension of the oil, allowing the oil to quickly fill the pre-inlet tank. The two partitions are connected to form a bubble confluence channel, allowing bubbles to pass through quickly, reducing bubble escape resistance, and further accelerating the rapid filling of the pre-inlet tank, thus improving the oil's flow efficiency. The oil first enters the pre-inlet tank and then flows into the atomizing tank through the connecting hole, suppressing oil supply fluctuations, reducing the impact of oil on the atomizing tank, and effectively buffering the oil flow rate entering the atomizing tank. This ensures that the oil temperature and quantity entering the atomizing tank through the connecting hole are consistent, guaranteeing the continuous stability and consistency of the oil supply.

[0031] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0032] This disclosure relates to an inlet partition structure, including an atomizing component and an atomizing chamber assembly. The atomizing component is used to atomize liquid oil. The atomizing chamber assembly includes an atomizing shell, a first support, a second support, and an oil sealing element. An atomizing oil chamber is formed between the atomizing shell and the first support. The atomizing component is installed in the atomizing oil chamber. The first support has a connecting hole. A pre-inlet oil chamber is formed between the first support and the second support, communicating with the connecting hole. The connecting hole communicates with the atomizing oil chamber. The oil sealing element passes through the... Inside the atomizing housing, one end of the oil sealing element is movably installed in the connecting hole; the second bracket has a connecting part protruding from one end opposite to the first bracket, and an oil inlet column protruding in the connecting groove of the connecting part, the oil inlet column having an oil inlet hole, the oil inlet hole communicating with the pre-oil inlet chamber; at least two partition plates protruding from the inner wall of the oil inlet hole, the two partition plates being arranged opposite to each other, the two partition plates dividing the oil inlet hole into two connected oil inlet channels, the two oil inlet channels communicating along the extension direction of the partition plates. When the oil enters the oil inlet 2302 under the action of gravity, the oil inlet 2302 is divided into two parallel oil inlet channels 2303 by the partition plate 232. The partition plate 232 breaks the surface tension of the oil, so that the oil quickly fills the pre-inlet oil chamber 202. The two partition plates 232 are connected to form a bubble confluence channel, which allows bubbles to pass through quickly, reduces the escape resistance of bubbles, and further accelerates the rapid filling of the pre-inlet oil chamber 202, thus improving the oil guiding efficiency. The oil first enters the pre-inlet oil chamber 202, and then flows into the atomizing oil chamber 201 through the connecting hole 2201, which suppresses the oil supply fluctuation, reduces the impact of the oil on the atomizing oil chamber 201, and ensures the stability of the oil supply entering the atomizing oil chamber 201.

[0033] like Figures 1 to 3 As shown, this is an embodiment of the feed inlet partition structure 10 of this disclosure, including an atomizing component 100 and an atomizing chamber assembly 200. The atomizing component 100 is used to atomize oil. The atomizing chamber assembly 200 includes an atomizing shell 210, a first support 220, a second support 230, and an oil sealing element 240. An atomizing oil chamber 201 is formed between the atomizing shell 210 and the first support 220. The atomizing component 100 is installed in the atomizing oil chamber 201. The first support 220 has a connecting hole 2201. A pre-filling oil chamber 202 is formed between the first support 220 and the second support 230, communicating with the connecting hole 2201. The connecting hole 2201 communicates with the atomizing oil chamber 201. The oil sealing element 240 passes through the atomizing shell 210, and one end of the oil sealing element 240 is movably installed in the connecting hole 2201.

[0034] Furthermore, the second bracket 230 has a connecting portion 221 protruding from one end opposite to the first bracket 220. The connecting portion 221 has a connecting groove 2301, and an oil inlet column 231 protrudes from the connecting groove 2301. The oil inlet column 231 has an oil inlet hole 2302, which is used to communicate with the oil bottle. The oil inlet hole 2302 is connected to the pre-oil inlet chamber 202. A partition plate 232 is provided inside the oil inlet hole 2302. One end of the partition plate 232 is fixedly connected to the inner wall of the oil inlet hole 2302. The partition plate 232 protrudes from the inner wall of the oil inlet hole 2302, and the partition plate 232 divides the oil inlet hole 2302 into two connected oil inlet channels 2303. The two oil inlet channels 2303 are connected along the extension direction of the partition plate 232.

[0035] In this embodiment, after the atomizing shell 210 is inverted, the oil sealing component 240 is controlled to open the connecting hole 2201. The oil in the oil bottle enters the oil inlet 2302 under the action of gravity. The partition plate 232 forms two parallel oil inlet channels 2303. The oil is sheared by the partition plate 232 to form turbulence, which breaks the surface tension of the oil and reduces the flow resistance, so that the oil can smoothly enter the pre-oil inlet chamber 202. At the same time, the bubbles rise to the top of the pre-oil inlet chamber 202. The through area of ​​the partition plate 232 forms a bubble confluence channel, which allows larger bubbles to pass through quickly, reducing the escape resistance of the bubbles, so that the bubbles can quickly pass through the oil inlet 2302 along the dual channels. The oil needs to enter the pre-oil inlet chamber 202 first. The pre-oil inlet chamber 202 buffers the impact of the oil, and then slowly releases it into the atomizing oil chamber 201 through the pre-oil inlet chamber 202 and the connecting hole 2201.

[0036] The aforementioned feed inlet partition structure 10, when the oil enters the oil inlet hole 2302 under the action of gravity, divides the oil inlet hole 2302 into two parallel oil inlet channels 2303 by the partition plate 232. The partition plate 232 breaks the surface tension of the oil, allowing the oil to quickly fill the pre-inlet oil chamber 202. The two partition plates 232 are connected to form a bubble confluence channel, allowing bubbles to pass through quickly, reducing the bubble escape resistance, further accelerating the rapid filling of the pre-inlet oil chamber 202, and improving the oil guiding efficiency. The oil first enters the pre-inlet oil chamber 202, and then flows into the atomizing oil chamber 201 through the connecting hole 2201, suppressing the oil supply fluctuation, reducing the impact of the oil on the atomizing oil chamber 201, effectively buffering the oil flow rate entering the atomizing oil chamber, and ensuring the oil supply temperature and quantity entering the atomizing oil chamber 201 through the connecting hole 2201, thus ensuring the continuous stability and consistency of the oil supply.

[0037] like Figure 3As shown, in one embodiment, wedge-shaped grooves 2304 are respectively formed on both sides of the circumference of the oil inlet column 231, and the wedge-shaped grooves 2304 are connected to the oil inlet hole 2302. In this embodiment, the wedge-shaped grooves 2304 guide the oil into the oil inlet hole 2302 along a specific path, reducing the flow resistance of the oil in the circumference of the oil inlet column 231 and reducing energy loss. The geometric structure of the wedge-shaped grooves 2304 changes the oil flow path, triggers local turbulence, effectively breaks the surface tension of the oil, accelerates the process of oil filling the pre-inlet tank 202, and disperses the impact force of the oil, reducing the risk of deformation of the oil inlet column 231 due to fluid pressure.

[0038] like Figure 3 As shown, in one embodiment, each of the wedge-shaped grooves 2304 is formed with a first inclined surface 2311 and a second inclined surface 2312, with the first inclined surface 2311 and the second inclined surface 2312 forming a first angle. In this embodiment, the double-inclined structure triggers local turbulence by changing the oil flow path, and the shear force generated by the turbulence further increases the surface tension of the oil. The wedge-shaped grooves 2304 guide bubbles to rise along the first inclined surface 2311 and the second inclined surface 2312 of the wedge-shaped grooves 2304, preventing bubbles from accumulating at the inlet of the oil inlet 2302. The first inclined surface 2311 and the second inclined surface 2312 of the wedge-shaped grooves 2304, together with the dual-channel structure of the partition plate 232, achieve efficient oil flow and stable oil supply, further enhancing the flow efficiency and oil supply stability of the inlet partition structure 10.

[0039] like Figure 3 As shown, in one embodiment, each of the partition plates 232 is formed with a third inclined surface 2321 and a fourth inclined surface 2322, and the third inclined surface 2321 and the fourth inclined surface 2322 form a second included angle. In this embodiment, the third inclined surface 2321 and the fourth inclined surface 2322 change the oil flow path, triggering local turbulence to disrupt the surface tension of the oil, so that the oil forms a more uniform flow distribution when entering the oil inlet 2302, reducing flow resistance and accelerating the filling process. The inclined surface of the partition plate 232 and the wedge-shaped groove 2304 work together to achieve efficient oil guidance and stable oil supply.

[0040] like Figure 3As shown, in one embodiment, the first included angle and the second included angle are set correspondingly. In this embodiment, when the oil flows into the oil inlet column 231 area, the first included angle of the wedge-shaped groove 2304 affects the circumferential and radial diversion and acceleration effect of the oil. The second included angle on the partition plate 232 corresponds to the first included angle, which can further precisely control the flow direction and speed of the oil after it enters the oil inlet hole 2302, forming a continuous and optimized flow path. At the wedge-shaped groove 2304, the oil generates turbulence in a specific direction due to the effect of the first included angle. When the oil enters the oil inlet hole 2302, the second included angle of the partition plate 232 can continue and enhance this turbulence effect, so that the oil always maintains an efficient and stable flow state throughout the oil inlet process. At the same time, it coordinates the movement of air bubbles and avoids the accumulation or turbulent flow of air bubbles in the oil inlet hole 2302, further ensuring the smoothness of oil guidance and the stability of oil supply.

[0041] like Figure 4 As shown, in one embodiment, the cross-section of the connecting hole 2201 is an elongated elliptical structure with semicircular ends, and the outer edge of the sealing element 240 corresponds to the connecting hole 2201. In this embodiment, the connecting hole 2201 transitions through a smooth curve, which reduces the collision and friction between the oil and the hole wall during flow, thereby effectively reducing the flow resistance of the oil. The cross-section of the connecting hole 2201 is larger than that of a circular hole. Under the same pressure conditions, the larger cross-section allows more oil to pass through, significantly increasing the amount of oil entering the atomizing oil chamber 201 from the pre-inlet oil chamber 202, thus better meeting the oil supply demand. Due to the larger cross-section of the connecting hole 2201, the resistance encountered by bubbles rising in the oil is correspondingly reduced. Bubbles can pass through the connecting hole 2201 more easily, reducing the accumulation and residence time of bubbles in the hole, improving the bubble discharge efficiency, thereby shortening the oil filling time and improving the continuity of oil supply.

[0042] like Figure 3 As shown, in one embodiment, the oil inlet 2302 and the connecting hole 2201 are eccentrically positioned. In this embodiment, the eccentric positioning of the oil inlet 2302 and the connecting hole 2201 reduces sudden changes in local pressure, alters the oil path, and reduces the velocity difference at various points entering the pre-oil chamber 202. This improves the laminar flow stability of the oil through the connecting hole 2201. When the oil flows from the oil inlet 2302 to the connecting hole 2201, the eccentric positioning causes a certain change in the flow direction of the oil, avoiding excessive pressure differences in local areas. This reduces oil turbulence, allowing the oil to enter the atomizing oil chamber 201 through the connecting hole 2201 in a more stable state, thus improving the stability and uniformity of oil supply.

[0043] like Figure 3 and Figure 5As shown, the second bracket 230 is made of silicone. The oil sealing component 240 includes a movable rod 241 and a sealing plate 242. The movable rod 241 passes through the atomizing oil chamber 201. The sealing plate 242 is connected to one end of the movable rod 241. An annular inclined surface is formed on the side of the sealing plate 242 adjacent to the connecting hole 2201. The annular inclined surface abuts against the inner wall of the connecting hole 2201. In this embodiment, the movement of the sealing plate 242 is achieved by operating the movable rod 241, thereby controlling the opening and closing of the connecting hole 2201. The movable rod 241 is made of a material with certain strength and corrosion resistance to ensure stable operation in an oily environment. When the sealing component 240 closes the connecting hole 2201, an annular inclined surface is formed on the side of the sealing plate 242 adjacent to the connecting hole 2201. The annular inclined surface abuts against the inner wall of the connecting hole 2201, so that the annular inclined surface and the inner wall of the connecting hole 2201 fit tightly to form a good sealing effect, which can effectively prevent oil from flowing back from the atomizing oil chamber 201 to the pre-inlet oil chamber 202. The presence of the annular bevel allows the sealing plate 242 to better disperse pressure when in contact with the inner wall of the connecting hole 2201, reducing local stress concentration, reducing wear on the sealing plate 242 and the inner wall of the connecting hole 2201, and extending its service life. The sealing plate 242 is made of metal, which has high strength and hardness, making it less prone to deformation when subjected to oil pressure and the tension of the moving rod 241, thus maintaining a stable shape and structure. The metal material has good wear resistance, which can reduce frictional wear with the inner wall of the connecting hole 2201 during frequent opening and closing, ensuring the sealing performance and service life of the oil sealing component 240.

[0044] like Figure 5 As shown, further, a portion of the sealing plate 242 is located above the two oil inlet channels 2303. In this embodiment, when it is necessary to return the oil from the atomizing oil chamber 201 to the oil bottle, the oil flows from the connecting hole 2201 through the pre-inlet chamber 202 and then into the oil bottle through the oil inlet hole 2302. By moving the movable rod 241, the sealing plate 242 opens and closes the connecting hole 2201. During the movement of the sealing plate 242, a portion of the sealing plate 242 can push the oil in the two oil inlet channels 2303 of the connecting hole, thereby accelerating the return of the oil to the oil bottle.

[0045] like Figure 3As shown, further, in one embodiment, the two sides of each of the partition plates 232 form an arc transition surface with the inner wall of the oil inlet hole 2302. In this embodiment, the arc transition surface is a smooth curve transition, making the inner walls of the two oil inlet channels 2303 smooth, eliminating right angles or sharp turns between the partition plates 232 and the inner walls of the oil inlet hole 2302, reducing boundary layer separation of oil on both sides of the partition plates 232, thereby significantly reducing pressure drop, allowing oil to enter the pre-oil inlet chamber 202 through the smooth flow channel, while air bubbles are discharged along the smooth flow channels on both sides, avoiding oil supply fluctuations and ensuring the stability of oil supply.

[0046] like Figure 5 As shown, further, in one embodiment, a confluence channel 2101 communicating with the atomizing oil chamber 201 is provided on one side of the atomizing housing 210. The end of the connecting hole 2201 opposite to the pre-inlet oil chamber 202 is connected to the confluence channel 2101 and the atomizing oil chamber 201. It can be understood that the confluence channel 2101 provides a space for concentrated oil collection. When it is necessary to release the oil from the atomizing oil chamber 201, the atomizing housing 210 can be tilted, and gravity will cause the oil to naturally collect in the confluence channel 2101. The connecting hole 2201 is then opened, allowing the oil to enter the pre-inlet oil chamber 202 from the connecting hole 2201, and then flow back into the oil bottle through the oil inlet hole 2302. This makes the oil collection more concentrated and convenient, avoiding oil residue or dispersion in the atomizing oil chamber 201 and improving the oil release efficiency.

[0047] like Figure 5 As shown, in one embodiment, the manifold 2101 has a transition surface on the side opposite to the connecting hole 2201, and the transition surface is connected to the inner wall of the atomizing oil tank 201. In this embodiment, when oil flows from the connecting hole 2201 into the manifold 2101, the transition surface can guide the oil to smoothly change its flow direction along its surface, allowing the oil to more naturally converge and flow into the atomizing oil tank 201. This design avoids collisions and disturbances caused by sudden changes in direction at the connection between the manifold 2101 and the atomizing oil chamber 201, reducing energy loss and improving oil flow efficiency. When it is necessary to release the oil from the atomizing oil chamber 201, the tilting of the atomizing shell 210 causes the oil to converge in the manifold 2101. The transition surface guides the oil to flow more smoothly from the manifold 2101 through the connecting hole 2201 into the pre-inlet oil chamber 202, and then back into the oil bottle through the inlet hole 2302. Its smooth shape reduces the resistance of the oil during the return flow process, avoids oil residue in the structure, and improves the efficiency and thoroughness of oil discharge.

[0048] like Figure 5As shown, further, the second bracket 230 has an oil guide groove 2306 on the side opposite to the first bracket 220. The atomizing component 100 is installed in the oil guide groove 2306, and the oil guide groove 2306 is connected to the connecting hole 2201. In this embodiment, the oil first enters the pre-oil inlet chamber 202, where it undergoes pressure buffering and initial stabilization. It then flows into the oil guide groove 2306 through the connecting hole 2201. The oil guide groove 2306 precisely guides the oil to the atomizing component 100, ensuring a stable and uniform supply of oil to the atomizing component 100. When oil needs to be drained, the atomizing shell 210 is tilted to allow the oil to collect in the confluence groove 2101. The oil guide groove 2306 and the connecting hole 2201 ensure smooth flow of oil between the pre-oil inlet chamber 202 and the atomizing component 100, preventing oil residue within the structure.

[0049] like Figure 1 As shown, in one embodiment, the end of the oil inlet column 231 facing away from the second bracket 230 is flush with the connecting portion 221. In this embodiment, the oil inlet column 231 is protected within the connecting portion, which provides effective buffering and protection for the oil inlet column 231, reducing the direct impact of external forces on the oil inlet column 231 and lowering the probability of the oil inlet column 231 breaking or deforming due to collision.

[0050] like Figure 1 As shown, in one embodiment, the first support 220 has a first pre-storage slot 2202 on the side opposite to the atomizing housing 210, and the second support 230 has a second pre-storage slot 2305 on the side opposite to the connecting slot 2301. The first pre-storage slot 2202 and the second pre-storage slot 2305 together form the pre-oil inlet chamber 202. In this embodiment, when the first support 220 and the second support 230 are assembled, the first pre-storage slot 2202 and the second pre-storage slot 2305 are relatively close and tightly fitted, so that the first pre-storage slot 2202 and the second pre-storage slot 2305 cooperate to form a relatively independent and sealed pre-oil inlet chamber 202, thereby making the pre-oil inlet chamber 202 structurally stable.

[0051] like Figure 1 and Figure 5As shown, further, in one embodiment, the bottom of the second pre-storage slot 2305 is formed with a guide plane 233 and a guide curved surface 234, the oil inlet 2302 is opened at the bottom of the guide plane 233, and the outer edge of the guide plane 233 is connected to the guide curved surface 234. In this embodiment, the guide surface 234 forms an inclined surface relative to the guide plane 233. Utilizing gravity, the oil naturally converges towards the guide surface 234. The oil inlet 2302 is located at or near the end of the guide surface 234, allowing the oil to smoothly flow into the guide plane 233 after being converged and guided by the guide surface 234. This allows the oil in the second pre-storage tank 2305 to flow back into the oil bottle smoothly under gravity, avoiding oil residue in the second pre-storage tank 2305. When the atomizing shell 210 is inverted, air bubbles are generated during the process of the oil entering the connecting hole 2201 through the first pre-storage tank 2202. The guide surface 234 guides the air bubbles to move towards the oil inlet 2302 in the guide plane 233, allowing the oil to quickly and smoothly enter the second pre-storage tank 2305 through the oil inlet 2302, preventing the accumulation of air bubbles in the device and ensuring normal oil flow.

[0052] This application also provides an aerosol generating device, including an oil bottle, an atomizing base, and the feed inlet partition structure 10 described in any of the above embodiments. The oil bottle is connected to the oil inlet 2302, the atomizing base has a receiving groove, and the oil bottle is installed in the receiving groove. In this embodiment, the aerosol generator is equipped with a power supply component, which is installed inside the atomizing base and electrically connected to the atomizing component. The power supply component and the oil bottle are respectively located on both sides of the atomizing base, and the oil inlet corresponds to the position of the oil bottle. The atomizing base and the feed inlet partition structure of the aerosol generator adopt a layered structure, and the physical isolation and functional integration of the oil bottle and the power supply component are achieved through the atomizing base. The oil bottle is embedded in the receiving groove of the atomizing base and is arranged on both sides of the power supply component to form a thermal isolation protection system, which optimizes the spatial layout of the aerosol generator. Through the feed inlet partition structure 10, a buffer oil storage area is formed by the pre-filled oil tank, which effectively balances the oil supply pressure fluctuation of the oil bottle, thereby reducing impact and extending the service life of the aerosol generator. The partition plate of the oil inlet breaks the surface tension of the oil, accelerates the oil flow efficiency, achieves stable oil supply control, accelerates the filling effect of the atomizing oil tank, thereby improving the atomization response speed and improving the user experience.

[0053] Compared with the prior art, this disclosure has at least the following advantages:

[0054] The aforementioned feed inlet partition structure 10, when the oil enters the oil inlet hole 2302 under the action of gravity, divides the oil inlet hole 2302 into two parallel oil inlet channels 2303 by the partition plate 232. The partition plate 232 breaks the surface tension of the oil, allowing the oil to quickly fill the pre-inlet oil chamber 202. The two partition plates 232 are connected to form a bubble confluence channel, allowing bubbles to pass through quickly, reducing the bubble escape resistance, further accelerating the rapid filling of the pre-inlet oil chamber 202, and improving the oil guiding efficiency. The oil first enters the pre-inlet oil chamber 202, and then flows into the atomizing oil chamber 201 through the connecting hole 2201, suppressing the oil supply fluctuation, reducing the impact of the oil on the atomizing oil chamber 201, effectively buffering the oil flow rate entering the atomizing oil chamber, and ensuring the oil supply temperature and quantity entering the atomizing oil chamber 201 through the connecting hole 2201, thus ensuring the continuous stability and consistency of the oil supply.

[0055] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
