Detailed implementation manners

[0028] It should be understood that the terms, specific structures and functional details disclosed here are only for describing specific embodiments and are representative. However, the present invention can be specifically implemented in many alternative forms and should not be construed as being limited only to the embodiments described herein.

[0029] The present invention will be further described below with reference to the accompanying drawings and optional embodiments.

[0030] As Figures 1 to 7As shown in the figure, an embodiment of the present invention discloses an oil core separation structure, which includes a mouthpiece 100, an oil cup 200, a sealing assembly 300, an air duct 400, an atomizing core 500, and a base 600. The oil cup 200 is connected to the mouthpiece 100 to form a first oil reservoir 210 for containing e-liquid. Of course, the mouthpiece 100 and the oil cup 200 can also be integrally formed as the outer shell of the cartridge. A receiving hole 211 is provided at the bottom of the first oil reservoir 210. A first oil inlet hole 310 is provided on the outer peripheral side of the sealing assembly 300. The sealing assembly 300 is embedded in the receiving hole 211 and can slide, so that the first oil inlet hole 310 communicates with the first oil reservoir 210 after being exposed from the receiving hole 211. One end of the air duct 400 is inserted into the sealing assembly 300 and the sealing assembly 300 can slide on the air duct 400, and the other end is inserted and communicated with the mouthpiece 100. The atomizing core 500 is connected to the air duct 400 and is arranged in the sealing assembly 300. The first oil inlet hole 310 communicates with the atomizing core 500. The base 600 is connected to the bottom of the sealing assembly 300 and is slidably arranged on the oil cup 200. Wherein, an external force acts on the base 600 to drive the sealing assembly 300 to slide in the receiving hole 211 to close or expose the first oil inlet hole 310.

[0031] In the oil core separation structure of the embodiment of the present invention, by providing the first oil inlet hole 310 on the sealing assembly 300, the sealing assembly 300 is slidably connected relative to the air duct 400 and the receiving hole 211, and the base 600 and the sealing assembly 300 are linked. An external force acting on the base 600 can drive the sealing assembly 300 to slide relative to the air duct 400 and the receiving hole 211, and the air duct 400 remains stationary, so that the first oil inlet hole 310 is exposed or closed, and the atomizing core 500 and the oil core can be separated and controlled according to the needs of the user, avoiding the problem of e-liquid leakage caused by the long-term contact between the e-liquid and the atomizing core 500. At the same time, by pushing the base 600 to open the oil inlet of the atomizing core 500, it is avoided that during the transportation or sale of the product when it is not in use, the e-liquid accidentally enters the atomizing core 500 due to the extrusion and collision of objects, further improving the stability of e-liquid sealing.

[0032] As Figure 3 shown, before use, the base 600 is in the first position, the corresponding sealing assembly 300 is at the lower position of the receiving hole 211, and the first oil inlet hole 310 is located in the receiving hole 211, so that the first oil inlet hole 310 is blocked by the side wall of the receiving hole 211. When the user needs to use it, push the base 600 in the direction of the oil cup 200, so that the sealing assembly 300 synchronously rises in the receiving hole 211 to expose the first oil inlet hole 310 of the sealing assembly 300. The e-liquid can pass through the first oil inlet hole 310 from the first oil reservoir 210 and then enter the atomizing core 500 in the air duct 400. AsFigure 4 As shown, at this time, the base 600 is in the second position, and the atomization core 500 can work normally, so that aerosol can be generated by atomization.

[0033] It should be noted that in the above solution, the base 600 can only be pushed from the first position to the second position and cannot be pulled back from the second position to the first position; it can also be repeatedly moved and switched between the first position and the second position, and no specific limitation is made.

[0034] In the solution of repeatedly moving and switching between the first position and the second position, when it is necessary to block the e-liquid in the first oil chamber 210 from entering the atomization core 500, by pulling the base 600 in the opposite direction, the base 600 is pulled from the second position to the first position, so that the sealing component 300 moves downward synchronously in the receiving hole 211, so that the first oil inlet hole 310 is moved to abut against the side wall of the receiving hole 211 and is blocked by the side wall of the receiving hole 211 again, thereby closing the first oil inlet hole 310, and the e-liquid cannot enter the atomization core 500, so it does not work and cannot generate aerosol, isolating the long-term contact between the e-liquid and the atomization core 500 and preventing oil leakage.

[0035] Of course, one or more first oil inlet holes 310 and second oil inlet holes 410 can be provided.

[0036] As Figures 2 to 7 shown, the sealing component 300 includes a first seal 320 and a first bracket 330. One end of the first seal 320 is slidably connected to the air duct 400, and the other end is connected to the base 600. The first bracket 330 is arranged in the first seal 320 and is located between the first seal 320 and the air duct 400. Both ends of the first bracket 330 respectively abut against both ends in the sliding direction of the first seal 320.

[0037] When an external force acts on the base 600 to move, it drives the first seal 320 and the first bracket 330 to move synchronously. In this embodiment, a receiving cavity (not shown) is provided in the first seal 320, and the first bracket 330 can provide a force fulcrum for the first seal 320 based on the abutting action at both ends of the receiving cavity. The base 600 drives the first seal 320 to move upward or downward in the receiving hole 211. The first seal 320 slides relative to the receiving hole 211 and the air duct 400. The first seal 320 can be made of silica gel or rubber material, preferably silica gel material. The first seal 320 has good sealing performance but large friction. The first bracket 330 can play a role of supporting and transmitting force in the receiving cavity, making the first seal 320 slide smoothly without deformation, that is, it is convenient for the user to drive the first seal 320 through the base 600 to open or close the first oil inlet.

[0038] Specifically, as Figure 2 and Figure 3 shown, the first oil inlet hole 310 includes a first main oil inlet hole 311 and a first secondary oil inlet hole 312. The first main oil inlet hole 311 is provided on the first seal 320, and the first secondary oil inlet hole 312 is provided on the first bracket 330. A second oil chamber 340 for containing e-liquid is formed between the first bracket 330 and the outer wall of the air duct 400. The second oil chamber 340 is respectively communicated with the first secondary oil inlet hole 312 and the second oil inlet hole 410. By forming the second oil chamber 340 between the first bracket 330 and the air duct 400, the e-liquid in the first oil chamber 210 enters the second oil chamber 340 through the first main oil inlet hole 311 and the first secondary oil inlet hole 312 respectively, and then enters the second oil inlet hole 410 and then enters the atomization core 500, realizing the function of the oil core. Moreover, the second oil chamber 340 has an oil storage function to keep the e-liquid in the atomization core 500 sufficient.

[0039] More specifically, as Figure 2 、 Figures 5 to 7 shown, the first main oil inlet hole 311 and the first secondary oil inlet hole 312 are on the same horizontal plane. A transition groove 350 is provided around the inner wall of the first seal 320, and the first main oil inlet hole 311 and the first secondary oil inlet hole 312 are provided in the area corresponding to the transition groove 350. The first bracket 330 is inserted into the first seal 320. A transition groove 350 is provided on the inner wall of the first seal 320, which is recessed outward. The transition groove 350 is arranged around the horizontal plane of the first main oil inlet hole 311 and also has a certain oil storage function and is communicated with the first secondary oil inlet hole 312. In this way, even if the first bracket 330 can rotate at any angle in the first seal 320, the e-liquid in the transition groove 350 can enter the first secondary oil inlet hole 312 and then enter the second oil chamber 340 to supply e-liquid to the atomization core 500. Not only that, a recessed transition groove 350 is also provided on the outer wall of the first seal 320, and this transition groove 350 has a function of receiving and guiding the e-liquid, facilitating the entry of the e-liquid.

[0040] At the same time, on the outer wall of the first seal 320, corresponding to the upper and lower sides of the first main oil inlet hole 311, a sealing ring structure (not shown) protruding outward is provided, and at the upper and lower ends where the first seal 320 is inserted into the air duct 400, a sealing ring structure (not shown) protruding outward toward the outer wall of the air duct 400 is also provided to improve the sealing performance.

[0041] In another embodiment, as Figures 8 to 10As shown, the sealing assembly 300 includes a second bracket 360, a second seal 370, a third seal 380, and two sealing rings 390. The first oil inlet hole 310 is provided on the second bracket 360. One end of the second bracket 360 is slidably connected to the air duct 400, and the other end is connected to the base 600. The second seal 370 and the third seal 380 are respectively provided at both ends of the second bracket 360 and abut against the air duct 400. The sealing rings 390 are sleeved on the outer wall of the second bracket 360, above the first oil inlet hole 310. The sealing assembly 300 is of a split structure and is easy to install. The second bracket 360 serves as the main force-bearing body and is made of a hard material that is not easily deformed and will not deform when stressed, ensuring good sealing performance.

[0042] Specifically, the air duct 400 is inserted into the second bracket 360 and passes through both ends of the second bracket 360. The second seal 370 and the third seal 380 are respectively provided at the openings at both ends of the second bracket 360 and abut against the air duct 400 to seal the openings. The second seal 370 and the third seal 380 can be made of silicone or rubber, preferably silicone. The second seal 370 prevents the e-liquid in the first oil chamber 210 from entering the second oil chamber 340 from the top, and the third seal 380 prevents the e-liquid in the first oil chamber 210 and the second oil chamber 340 from leaking out. At the same time, the lower end of the second bracket 360 abuts against the air duct 400, and the third seal 380 also abuts against the lower end, the side wall of the second bracket 360, and the outer wall of the air duct 400, which restricts the third seal 380 and prevents it from being misaligned when pushed upward, ensuring synchronous movement with the second bracket 360.

[0043] More specifically, the sealing ring 390 is sleeved above the first oil inlet hole 310 and is correspondingly embedded and positioned through the installation groove. When the first oil inlet hole 310 is closed, the sealing ring 390 isolates the first oil inlet hole 310 from the first oil chamber 210, preventing e-liquid from leaking into the first oil inlet hole 310 in the closed state. Additionally, a sealing ring 390 can also be provided at the lower end of the first oil inlet hole 310. When the base is pushed to expose the first oil inlet hole 310, the e-liquid in the first oil chamber 210 enters the second oil chamber 340 through the first oil inlet hole 310. The sealing ring 390 and the third seal 380 prevent the e-liquid in the first oil chamber 210 and the second oil chamber 340 from leaking out. The sealing ring can be made of silicone or rubber, preferably silicone.

[0044] As Figure 3 and Figure 4As shown, an electrode assembly 230 is provided at the bottom of the oil cup 200. The electrode assembly 230 is electrically connected to the atomization core 500. An avoidance hole 610 for avoiding the electrode assembly 230 is provided on the base 600. When the base 600 slides to close the first oil inlet hole 310, the electrode assembly 230 is placed inside the avoidance hole 610. When the base 600 slides to expose the first oil inlet hole 310, the electrode assembly 230 is flush with or exposed outside the opening of the avoidance hole 610.

[0045] The electrode assembly 230 is provided at the bottom of the oil cup 200. The electrode assembly 230 includes two symmetrically arranged power-consuming electrodes. The electrode assembly 230 is inserted and fixed into a through groove (not shown) at the bottom of the oil cup 200 and is flush with the bottom of the oil cup 200. The top is sealed by a silica gel plug 260 to block the through groove of the oil cup 200. The electrode assembly 230 is arranged within the moving path of the avoidance hole 610 of the base 600. In the initial state, the base 600 is in the first position and is at a low position relative to the bottom of the oil cup 200. In this state, the first oil inlet hole 310 is closed, and the electrode assembly 230 is placed inside the base 600 and cannot be energized to work with the main unit. While ensuring the separation of the oil and the core, it also has the advantage of preventing dry burning when the cartridge is used for the first time. During use, the base 600 needs to be fully pushed up to make the electrode move downward relative to the avoidance hole 610 to expose the electrode assembly 230 so that it can be installed on the main unit to complete the electrical connection between the electrode assembly 230 and the main unit.

[0046] Further, a buckle 620 is provided on the base 600, and a first card slot 240 and a second card slot 250 are provided on the oil cup 200. When the buckle 620 is engaged with the first card slot 240, the first oil inlet hole 310 is exposed. When the buckle 620 is engaged with the second card slot 250, the first oil inlet hole 310 is closed, which enables better positioning of the exposed and closed states of the first oil inlet hole 310, avoids accidental triggering under external force, and also improves the positioning effect of the electrode assembly 230 from the hidden state to the exposed state.

[0047] Specifically, the buckle 620 is arranged on the outer arm of the base 600, the first slot 240 and the second slot 250 are arranged on the inner side wall of the bottom of the oil cup 200, and are at different horizontal planes. In the initial state, when the base 600 is in the first position, the buckle 620 is engaged with the second slot 250, and at this time, the first oil inlet hole 310 is closed in the receiving hole 211, and the smokeless oil enters the atomizer core 500. The electrode assembly 230 is also hidden in the deep avoidance hole 610 of the base 600 and cannot be electrically connected to the outside to prevent the smokeless oil from being discharged. In the case of oil, the user mistakenly operates the power-on and causes dry burning. When in use, the base 600 is pushed upward to disengage the buckle 620 from the second slot 250, and further moved upward until the buckle 620 is engaged with the first slot 240. At this time, the base 600 drives the sealing assembly 300 to move, so that the first oil inlet hole 310 is separated from the receiving hole 211 and exposed in the first oil tank 210. The oil channel is connected and the oil can be smoothly fed, and the electrode assembly 230 is also exposed from the avoidance hole 610 to the base 600, and is connected to the main body of the aerosol generating device. Preferably, the electrode assembly 230 is flush with the bottom of the base 600, and can only be energized with the main body when the base 600 is pushed up (at this time, the oil is supplied to the atomizer core 500), so as to achieve the purpose of preventing dry burning when used for the first time.

[0048] It should be noted that the buckle 620 can only be switched once between the second slot 250 and the first slot 240, that is, after pushing the base 600 to make the buckle 620 snap into the first slot 240 from the second slot 250, it cannot be withdrawn from the second slot 250 to the first slot 240. In other embodiments, the buckle 620 can be switched arbitrarily between the second slot 250 and the second slot 250, and can repeatedly realize the switching of the oil core separation function and the switching of the electrode assembly 230 from hidden to exposed. It works normally when in use and will not leak oil or dry burn when not in use.

[0049] In this embodiment, the buckle 620 can only switch between the second slot 250 and the first slot 240 once. Specifically, the surface in the moving direction of the buckle 620 is set to an arc surface, and the surface in the opposite direction is a plane. When the base 600 is pushed upward, the buckle 620 can pass from the second slot 250 to the first slot 240 through the arc surface contact, and the opposite direction is a plane contact and cannot be returned. In actual use, in the production state, that is, the state where the buckle 620 is engaged with the second slot 250, the first oil inlet 310 is closed, and the electrode assembly 230 is also hidden, realizing the oil core separation function in the unused state such as transportation or sale and the function of preventing accidental touch and dry burning after assembly.

[0050] Furthermore, when the buckle 620 is engaged with the first slot 240 , the first oil inlet hole 310 and the second oil inlet hole 410 are located at the same horizontal plane, so that the smoke oil can enter the atomizer core 500 of the air guide tube 400 faster and more fully.

[0051] In this embodiment, when the buckle 620 is clamped with the second card slot 250, the first oil inlet hole 310 is lower than the second oil inlet hole 410. That is, when there is a small amount of oil leakage in the sealing assembly 300, the e-liquid in the first oil inlet hole 310 will first enter the second oil chamber 340 and will not directly enter the second oil inlet hole 410. When the buckle 620 is clamped with the first card slot 240, the first oil inlet hole 310 and the second oil inlet hole 410 are at the same horizontal plane. The e-liquid in the first oil inlet hole 310 can enter the second oil chamber 340 from the first oil chamber 210 and smoothly enter the second oil inlet hole 410.

[0052] As Figure 2 and Figure 3 shown, the atomization core 500 includes an oil-absorbing cotton 510 and a heating wire 520. The oil-absorbing cotton 510 is sleeved on the heating wire 520. The oil-absorbing cotton 510 is arranged at a position corresponding to the second oil inlet hole 410 in the air guide tube 400. Since a second oil chamber 340 is formed between the first bracket 330 and the air guide tube 400, it can ensure sufficient oil supply to the oil-absorbing cotton 510 and can save the traditional cotton wrapped outside the heating core, thus saving costs.

[0053] It should be noted that in other embodiments, the atomization core 500 can also be a ceramic atomization core. The porous ceramic matrix is cylindrical, and the heating wire 520 or the heating film is arranged on the surface of the ceramic matrix.

[0054] More specifically, an isolation member 420 is arranged at the bottom end of the air guide tube 400. One end of the heating wire 520 is electrically connected to the electrode assembly 230, and the other end passes through the isolation member 420 and is connected to the oil-absorbing cotton 510. The isolation member 420 seals the heating wire 520 and the oil-absorbing cotton 510 in the air guide tube 400. By fixedly connecting the isolation member 420 with the air guide tube 400, the heating wire 520 and the oil-absorbing cotton 510 are also fixed in the air guide tube to prevent them from falling out. A through hole is arranged at the center of the isolation member 420 to form a part of the air passage to communicate with the outside atmosphere, so as to facilitate the user to suck out the aerosol generated by burning the e-liquid from the mouthpiece.

[0055] As another embodiment of the present invention, an aerosol generating device is disclosed, which includes a main body and the oil-core separation structure described in the above embodiment, and the oil-core separation structure is installed on the main body.

[0056] Specifically, a power supply and a power supply electrode electrically connected to the power supply are arranged on the main body. When the oil-core separation structure is installed on the main body, the electrode assembly is in contact conduction with the power supply electrode, so that the power supply supplies power to the heating wire to make it heat, heats the e-liquid in the oil-absorbing cotton, thereby generating aerosol, and discharges it from the air guide tube to the mouthpiece for the user to inhale.
