[0030] In addition, the terms "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly specified.

[0031] Please refer to Figures 1-6The electronic atomization device provided by the embodiment of the present application comprises a first oil tank 10, a second oil tank 30, and a fluid channel 20 connecting the first oil tank 10 and the second oil tank 30, wherein the fluid channel 20 has a first main body part 201 connected with the first oil tank 10 and a second main body part 202 connected with the second oil tank 30, the first main body part 201 and the second main body part 202 are connected, a first blocking piece 4 is movably arranged in the first main body part 201, a second blocking piece 5 is movably arranged in the second main body part 202, the first blocking piece 4 and the second blocking piece 5 have a blocking state for blocking the fluid channel 20 and an opening state for opening the fluid channel 20, and there is at least one blocking state, the first blocking piece 4 blocks the connection between the first oil tank 10 and the second main body part 202, and the second blocking piece 5 blocks the connection between the second oil tank 30 and the first main body part 201.

[0032] In the embodiment of the present application, taking the injection of atomization liquid into the first oil tank 10 through the second oil tank 30 as an example, during the injection of atomization liquid, the first blocking piece 4 and the second blocking piece 5 in the fluid channel 20 are in the opening state, and the atomization liquid in the second oil tank 30 flows to the first oil tank 10 through the fluid channel 20. When the electronic atomization device is in the working state, the atomization liquid in the first oil tank 10 is used for atomization and heating. The first blocking piece 4 and the second blocking piece 5 in the fluid channel 20 are in the blocking state, so that the atomization liquid in the second oil tank 30 cannot flow to the first oil tank 10 through the fluid channel 20, and the atomization liquid in the first oil tank 10 cannot flow back to the second oil tank 30 through the fluid channel 20, thereby achieving the sealing effect and preventing the first oil tank 10 from leaking. In addition, in actual application, one of the first blocking piece 4 and the second blocking piece 5 can be in the blocking state to achieve the sealing property of the device, thereby enhancing the practicability of the device. When the first blocking piece 4 in the first main body part 201 and the second blocking piece 5 in the second main body part 202 are both in the blocking state, the double sealing effect can be achieved, thereby further improving the air tightness in the blocking state and improving the leakage prevention effect.

[0033] It can be understood that the flow of the atomized liquid between the first oil tank 10 and the second oil tank 30 relies on the gravitational potential energy. In the case where the first oil tank 10 is formed inside the oil cup 1 of the electronic atomization device and the second oil tank 30 is an external oil tank, the first oil tank 10 can also inject the atomized liquid into the second oil tank 30 in the embodiment of the present application. Specifically, it can be determined according to the relative height positions of the first oil tank 10 and the second oil tank 30 in the axial direction of the electronic atomization device when the first blocking member 4 and the second blocking member 5 are in the open state. For example, when the first blocking member 4 and the second blocking member 5 are in the open state, along the axial direction of the electronic atomization device, the second oil tank 30 is located above the first oil tank 10, and then the second oil tank 30 injects the atomized liquid into the first oil tank 10. Conversely, the first oil tank 10 injects the atomized liquid into the second oil tank 30.

[0034] It can be understood that, Figure 1 The Z-axis direction shown is the axial direction.

[0035] For example, the first body part 201 and the second body part 202 can be near-fusiform, and the first blocking member 4 and the second blocking member 5 can be circular beads. The material of the circular beads can be dense glass, dense ceramic or stainless steel with a density greater than that of the atomized liquid, which is not easy to react with the tobacco tar and can avoid generating substances that pollute the tobacco tar.

[0036] Further, referring to Figures 3-5 The fluid channel 20 also has a communication part 203 that communicates between the first body part 201 and the second body part 202, and the communication part 203 is in a straight-through type or a curved type. Specifically, the communication part 203 is also arranged between the first body part 201 and the second body part 202. When the atomized liquid is injected, the atomized liquid flows from the second oil tank 30 to the second body part 202, then flows to the first body part 201 through the communication part 203, and finally flows to the first oil tank 10.

[0037] In some embodiments, the communication part 203 can be in a straight-through type. It can be understood that the flow of the atomized liquid between the first oil tank 10 and the second oil tank 30 relies on the gravitational potential energy. By setting the communication part 203 in a straight-through type, the bending part of the communication part 203 can be reduced, the unidirectionality of the change of the gravitational potential energy can be ensured, and the smooth flow of the atomized liquid can be ensured. At the same time, the difficulty of preparation can also be reduced.

[0038] In some embodiments, the communication part 203 can be in a curved type, so that the flow rate of the atomized liquid in the communication part 203 can be appropriately slowed down, and the first blocking member 4 and the second blocking member 5 or other structures can be prevented from being damaged by the strong impact force of the atomized liquid.

[0039] Further, referring to Figures 3-5, the first main body part 201 has a first opening 2011 communicating with the communicating part 203, when the first blocking piece 4 is a circular ball, the radial dimension of the circular ball is greater than the dimension of the first opening 2011; the second main body part 202 has a second opening 2021 communicating with the second oil reservoir 30, when the second blocking piece 5 is a circular ball, the radial dimension of the circular ball is greater than the dimension of the second opening 2021; in the blocking state, the first blocking piece 4 blocks the first opening 2011, and / or, the second blocking piece 5 blocks the second opening 2021.

[0040] In some specific embodiments, there are at least three blocking states between the first oil reservoir 10 and the second oil reservoir 20, which are specifically described as follows:

[0041] As shown in Figure 3 , in the first blocking state, the second blocking piece 5 blocks the second opening 2021, so that the atomized liquid in the second oil reservoir 30 cannot flow to the second main body part 202 through the second opening 2021, and thus cannot flow to the communicating part 203, and further cannot flow to the first main body part 201 and the first oil reservoir 10; further, when the first blocking piece 4 blocks the first opening 2011, the atomized liquid cannot flow to the first main body part 201 from the communicating part 203 through the first opening 2011, and thus cannot flow to the first oil reservoir 10. By blocking the first opening 2011 with the first blocking piece 4 and blocking the second opening 2021 with the second blocking piece 5, a double sealing effect can be achieved, further improving the air tightness in the blocking state and improving the leakage prevention effect;

[0042] As shown in Figure 5 , in the second blocking state, the first blocking piece 4 blocks the first opening 2011, and the second blocking piece 5 does not block the second opening 2021. Although the atomized liquid can flow from the second oil reservoir 30 to the first main body part 201 and the communicating part 203 through the second opening 2021, the atomized liquid cannot flow to the first oil reservoir 10 through the first opening 2011 by blocking the first opening 2011 with the first blocking piece 4, and thus the sealing effect can be achieved;

[0043] In the third blocking state, the first blocking piece 4 does not block the first opening 2011, and the second blocking piece 5 blocks the second opening 2021. By blocking the second opening 2021 with the second blocking piece 5, the atomized liquid in the second oil reservoir 30 cannot flow to the second main body part 202 through the second opening 2021. Therefore, although the first blocking piece 4 does not block the first opening 2011, the atomized liquid still cannot flow to the first oil reservoir 10, and thus the sealing effect can be achieved.

[0044] Further, please refer to Figures 3-5, one end of the first main body 201 opposite to the first opening 2011 has a first space 2012, one end of the second main body 202 opposite to the second opening 2021 has a second space 2022; in the open state, the first blocking piece 4 is located in the first space 2012, and the second blocking piece 5 is located in the second space 2022.

[0045] Specifically, as shown in Figure 4 , in the process of changing from the blocking state to the open state, the atomized liquid flowing from the second oil tank 30 pushes the second blocking piece 5 at the second opening 2021 to the second space 2022 by gravity, so as to realize the open state of the second blocking piece 5 at the second opening 2021; the atomized liquid flows to the communication part 203 through the second opening 2021, and also relies on gravity, the atomized liquid in the communication part 203 pushes the first blocking piece 4 at the first opening 2011 to the first space 2012, so that the first blocking piece 4 realizes the open state at the first opening 2011. In addition, the first main body 201 is provided with a third opening 2013 communicating with the first oil tank 10, and the second main body 202 is provided with a fourth opening 2023 between the second opening 2021 and the second space 2022, and the fourth opening 2023 can communicate with the communication part 203. Therefore, when the first blocking piece 4 and the second blocking piece 5 are both in the open state, the atomized liquid can flow from the second oil tank 30 to the second main body 202 through the second opening 2021, to the communication part 203 through the fourth opening 2023, to the first main body 201 through the first opening 2011, and finally to the first oil tank 10 through the third opening 2013.

[0046] It can be understood that, in the process of changing from the open state to the blocking state, the first blocking piece 4 moves from the first space 2012 to the first opening 2011 by relying on its own gravity; the second blocking piece 5 moves from the second space 2022 to the second opening 2021 by relying on its own gravity.

[0047] Further, please refer to Figures 3-5 , the first main body 201 is provided with an anti-blocking structure at the position of the first space 2012, and / or the second main body 202 is provided with a confluence part 200 at the position of the second space 2022 and the communication part 203.

[0048] In some embodiments, the first main body part 201 can be provided with an anti-sticking structure at the position of the first space 2012. Specifically, the anti-sticking structure can be a protrusion protruding from the inner wall of the first main body part 201. When the first blocking piece 4 is pushed into the first space 2012, the protrusion can effectively prevent the first blocking piece 4 from being stuck in the first space 2012. Therefore, when the first blocking piece 4 is in the process of changing from the open state to the blocking state, the gravity of the first blocking piece 4 can be prevented from being less than the sticking force so that the first blocking piece 4 cannot move out of the first space 2012, thereby preventing the subsequent work of the device from being affected.

[0049] In some embodiments, the anti-sticking structure can be a slope provided on the inner side of the first main body part 201, which can also prevent the first blocking piece 4 from being stuck in the first space 2012.

[0050] In some embodiments, a flow converging part 200 can be provided between the second main body part 202 and the communication part 203, and the flow converging part 200 is provided at the position of the second space 2022 of the second main body part 202. When the second blocking piece 5 moves back and forth between the second opening 2021 and the second space 2022 to switch between the blocking state and the open state, the fluid such as liquid or gas in the inner wall of the second main body part 202 can cause extrusion to the second blocking piece 5, which can hinder the movement of the second blocking piece 5. By providing the flow converging part 200 to communicate the second main body part 202 and the communication part 203, a circulating fluid circuit can be formed between the second main body part 202 and the communication part 203, thereby reducing the hindrance of the fluid to the second blocking piece 5.

[0051] In some embodiments, the first main body part 201 is provided with a first gas return groove communicated with the communication part 203 at the position of the first space 2012, and the second main body part 202 is provided with an anti-sticking structure at the position of the second space 2022, which can also prevent the first blocking piece 4 from being stuck in the first space 2012 and the second blocking piece 5 from being stuck in the second space 2022.

[0052] Further, as shown in Figures 3-5 , the first main body part 201, the communication part 203 and the second main body part 202 are sequentially arranged along the axial direction of the electronic atomization device, and the extension direction of the first main body part 201 and the extension direction of the second main body part 202 are both in an angular relationship with the axial direction.

[0053] In some specific embodiments, the first main body part 201, the communication part 203 and the second main body part 202 are sequentially arranged along the axial direction of the electronic atomization device. As shown in Figure 3 , when the electronic atomization device is placed in the normal direction, the first main body part 201 is located at the top, the second main body part 202 is located at the bottom, and the first oil reservoir 10 is located at the top of the second oil reservoir 30. As shown in Figure 4As shown, when the electronic atomizing device is placed in reverse, the first main body 201 is located at the bottom and the second main body 202 is located at the top; the first oil tank 10 is located at the bottom of the second oil tank 30.

[0054] Therefore, as Figure 3 As shown, the first blocking state is when the electronic atomizing device is placed upright. In this state, the first sealing member 4 seals the first opening 2011 by its own weight, and the second sealing member 5 seals the second opening 2021 by its own weight. It can be understood that at this time, the second oil tank 30 is located at the bottom of the first oil tank 10, thus the atomized liquid in the second oil tank 30 cannot flow to the first oil tank 10. Therefore, by setting the first sealing member 4 and the second sealing member 5, the purpose is essentially to prevent the atomized liquid in the first oil tank 10 from leaking into the second oil tank 30. The second and third blocking states are when the electronic atomizing device is placed horizontally. Figure 5 The flat position shown is the second blocking state. In this state, the first sealing component 4 blocks the first opening 2011 by its own weight, while the second sealing component 5 does not block the second opening 2021. The third blocking state can be... Figure 5 When the electronic atomizing device is rotated 180° and placed flat, the first sealing component 4 does not block the first opening 2011, and the second sealing component 5 blocks the second opening 2021 by its own weight.

[0055] like Figure 4 As shown, the open state is the state when the electronic atomizing device is placed in reverse. The atomizing liquid flows out of the second oil tank 30 at the top, pushing the second sealing member 5 from the second opening 2021 to the second space 2022. The atomizing liquid flows along the fluid channel 20, and the atomizing liquid pushes the first sealing member 4 from the first opening 2011 to the first space 2012.

[0056] Understandably, switching from the blocked state to the open state only requires changing the orientation of the e-cigarette device. Furthermore, the e-cigarette device is only in the open state when placed upside down. Therefore, when the e-cigarette device is used upright or flat, it remains in the blocked state, ensuring a tight seal during use.

[0057] Furthermore, the angle between the extension direction and the axial direction of the first main body 201 is between 5° and 80°, and / or the angle between the extension direction and the axial direction of the second main body 202 is between 5° and 80°.

[0058] Specifically, the angle between the extension direction of the first body part 201 and the axial direction can be 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, and the like. The angle between the extension direction of the second body part 202 and the axial direction can be 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, and the like. By changing the angle between the extension direction of each body part and the axial direction, the sliding track of the ball in the body part and the smoothness of movement can be changed.

[0059] In addition, the angle between the extension direction of the first body part 201 and the axial direction, and the angle between the extension direction of the second body part 202 and the axial direction, can be the same or different, and the first body part 201 and the second body part 202 can be on the same side in the axial direction or on opposite sides in the axial direction.

[0060] It should be noted that the number of sealing members and the structure of the fluid channel 20 are not limited in the embodiments of the present application. In actual application, the number of sealing members and the fluid channel 20 can be adjusted according to the arrangement of the first oil reservoir 10 and the second oil reservoir 30, so as to achieve the sealing effect.

[0061] Further, please refer to Figure 1 , Figure 2 and Figure 6 , the electronic atomization device comprises an oil cup 1, a connecting member 2, and a liquid storage bottle 3. The oil cup 1 is internally provided with a first oil reservoir 10 and an atomization core 7. The connecting member 2 is internally formed with a fluid channel 20. The liquid storage bottle 3 forms a second oil reservoir 30. The oil cup 1 and the connecting member 2 are fixedly assembled. The liquid storage bottle 3 and the connecting member 2 are detachably connected.

[0062] Specifically, the first oil reservoir 10 and the atomization core 7 are arranged inside the oil cup 1. The atomized liquid of the first oil reservoir 10 flows to the atomization core 7, so as to be heated and atomized by the atomization core 7 to form aerosol, which is provided for a user to smoke or use. The second oil reservoir 30 can serve as an external oil reservoir and is formed in the liquid storage bottle 3. Therefore, in the actual process, the electronic atomization device can be repeatedly used by replacing the liquid storage bottle 3. Compared with disposable products and reload products, the replacement cost of the electronic atomization device of the embodiments of the present application is low, which is more in line with the concept of green environmental protection, and can prolong the service life of the device. In addition, the liquid storage bottle 3 can be in a conventional bottle form. During transportation, the liquid storage bottle 3 can be transported separately, and the first oil reservoir 10 can be transported empty, so as to effectively prevent the atomized liquid in the first oil reservoir 10 from leaking onto other components of the electronic atomization device, and the problem of liquid leakage during transportation can be avoided.

[0063] Further, please refer to Figure 2The first body part 201 has a third opening 2013 communicating with the first oil reservoir 10, and the third opening 2013 is located at one side of the atomizing core 7 along the axial direction of the electronic atomizing device, and the direction of the third opening 2013 to the atomizing core 7 is the same as the direction of the first oil reservoir 10 to the second oil reservoir 30.

[0064] Specifically, the atomizing liquid can flow between the first oil reservoir 10 and the first body part 201 through the third opening 2013. When the electronic atomizing device is placed in the normal direction, the first oil reservoir 10 is located above the second oil reservoir 30, so that the third opening 2013 is located above the atomizing core 7. By arranging the third opening 2013 above the bottom of the first oil reservoir 10, when the electronic atomizing device is placed in the normal direction, even if the first oil reservoir 10 backflows, a certain amount of atomizing liquid can be ensured to be stored in the first oil reservoir 10, so that dry burning of the atomizing core 7 can be avoided.

[0065] Further, the connecting piece 2 includes a first part 21 and a second part 22, wherein the first part 21 is close to the oil cup 1 and is integrally formed with the oil cup 1, and the first part 21 and the second part 22 can be sealed by ultrasonic welding. Part of the fluid channel 20 is arranged in the first part 21, and another part of the fluid channel 20 is arranged in the second part 22, that is, the first part 21 and the second part 22 jointly form the fluid channel 20, facilitating the processing of the fluid channel 20.

[0066] It should be noted that the first body part 201, the second body part 202, the communication part 203, and the confluence part 200 in the fluid channel 20 are all partially arranged in the first part 21 and the other part is arranged in the second part 22.

[0067] Further, one of the first part 21 and the second part 22 is made of hard material, and the other can be made of soft rubber material, so that they can be sealed in a detachable sleeve joint manner, and when the sealing piece in the fluid channel 20 is aged, it can be disassembled and maintained or replaced.

[0068] Further, in some embodiments, the second part 22 is made of hard transparent material, the first part 21 is made of soft rubber material, and the second part 22 is sleeved outside the first part 21. By arranging the second part 22 as a transparent part, the user can directly observe the position state of the sealing piece in the fluid channel 20, and at the same time, laser welding can be used to seal and fix the two.

[0069] Further, please refer to Figure 6The electronic atomization device further comprises a sealing member 6, the connecting member 2 has a first interface end, the liquid storage bottle 3 has a second interface end, the first interface end and the second interface end are connected, and the sealing member 6 is clamped between the outer side wall of the first interface end and the inner side wall of the second interface end, at least one of the sealing member 6, the first interface end and the second interface end is provided with a first gas return groove 300 which communicates with the outside and the second oil reservoir 30.

[0070] Specifically, the sealing member 6 can be a silica gel member. The sealing member 6 can realize the sealed connection of the first interface end and the second interface end, so as to realize the sealing of the connecting position of the connecting member 2 and the liquid storage bottle 3. Therefore, when the electronic atomization device is placed in a normal direction, placed horizontally or placed in a reverse direction, the liquid leakage problem can be avoided. In addition, through the first interface end, the sealing member and the second interface end, the assembly connection of the connecting member 2 and the liquid storage bottle 3 can be realized, which has the effect of convenient operation. In addition, by opening the first gas return groove 300, when the electronic atomization device is placed in a reverse direction and the atomization liquid is injected from the second oil reservoir 30 to the first oil reservoir 10, as the atomization liquid in the second oil reservoir 30 decreases, the pressure in the second oil reservoir 30 will become smaller. Due to the pressure difference between the inside and the outside, the outside gas will enter the second oil reservoir 30 through the first gas return groove 300, so as to balance the gas pressure.

[0071] For example, the sealing member 6 and the outer side wall of the first interface end form the first gas return groove 300; and / or, the sealing member 6 and the inner side wall of the second interface end form the first gas return groove 300.

[0072] Further, referring to Figure 6 The end of the sealing member 6 close to the liquid storage bottle 3 is provided with an inner folded flange 61.

[0073] Specifically, the sealing member 6 can be an annular columnar structure, and the end of the sealing member 6 close to the liquid storage bottle 3 is provided with an inner folded flange, so as to ensure that the atomization liquid cannot flow out through the first gas return groove 300, and the liquid leakage problem can be avoided.

[0074] Further, the oil cup 1 is provided with a support which assembles the atomization core 7, and the support is provided with a second gas return groove. The second gas return groove is used for gas exchange when the electronic atomization device works, and when the electronic atomization device is placed in a reverse direction and the atomization liquid is injected into the first oil reservoir 10, the gas in the first oil reservoir 10 can be discharged to the outside through the second gas return groove.

[0075] In the above embodiments, the description of each embodiment has its own emphasis, and the part which is not described in detail in a certain embodiment can be referred to the related description of other embodiments.

[0076] The above is the description of the technical solutions provided by the present application.
