[0028] The embodiments of the utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the utility model, and cannot be understood as limiting the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.

[0030] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0031] See also Figure 1-6The embodiment of the utility model provides an electronic atomization device, comprising 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 201 connected to the first oil tank 10 and a second main body 202 connected to the second oil tank 30, the first main body 201 and the second main body 202 are connected, and a first blocking member 4 is movably provided in the first main body 201, and a second blocking member 5 is movably provided in the second main body 202, the first blocking member 4 and the second blocking member 5 have a blocking state for blocking the fluid channel 20 and an opening state for opening the fluid channel 20; there is at least one blocking state, the first blocking member 4 blocks the connection between the first oil tank 10 and the second main body 202, and the second blocking member 5 blocks the connection between the second oil tank 30 and the first main body 201.

[0032] In the embodiment of the utility model, taking the injection of atomized liquid into the first oil tank 10 through the second oil tank 30 as an example, during the injection of atomized liquid, the first blocking member 4 and the second blocking member 5 in the fluid channel 20 are both in an open state, and the atomized liquid in the second oil tank 30 will flow to the first oil tank 10 through the fluid channel 20. When the electronic atomization device is in a working state, the atomized liquid in the first oil tank 10 is used for atomization heating. The first blocking member 4 and the second blocking member 5 in the fluid channel 20 are in a blocking state, so that the atomized liquid in the second oil tank 30 cannot flow to the first oil tank 10 through the fluid channel 20, and the atomized liquid in the first oil tank 10 cannot flow back to the second oil tank 30 through the fluid channel 20, so that a sealing effect can be achieved, and leakage of the first oil tank 10 can be prevented. In addition, in practical applications, the sealing of the device can be achieved by having one of the first blocking member 4 and the second blocking member 5 in a blocking state, thereby enhancing the practicality of the device. When the first blocking member 4 in the first main body 201 and the second blocking member 5 in the second main body 202 of the fluid channel 20 are both in the blocking state, they can play a double sealing role, further improving the air tightness in the blocking state and improving the leakage prevention effect.

[0033] It is understandable that the circulation of the atomized liquid between the first oil tank 10 and the second oil tank 30 is achieved by gravity potential energy. In the case where the first oil tank 10 is not limited to be formed inside the oil cup 1 of the electronic atomization device and the second oil tank 30 is used as an external oil tank, the first oil tank 10 can also be used to inject atomized liquid into the second oil tank 30 in the embodiment of the utility model. Specifically, it can be judged according to the relative height position 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, the second oil tank 30 is located above the first oil tank 10 along the axial direction of the electronic atomization device, and the second oil tank 30 injects atomized liquid into the first oil tank 10. On the contrary, the first oil tank 10 injects atomized liquid into the second oil tank 30.

[0034] Understandably, Figure 1 The Z-axis direction shown is the axial direction.

[0035] For example, the first main body 201 and the second main body 202 may be nearly spindle-shaped, and the first blocking member 4 and the second blocking member 5 may be round balls. The round balls may be made of dense glass, dense ceramics, or stainless steel, etc., which have a density greater than that of the atomized liquid. These materials are not easy to react with the e-liquid, and can avoid the generation of substances that pollute the e-liquid.

[0036] For further information, see Figure 3-5 The fluid channel 20 also has a connecting portion 203 connecting the first main body 201 and the second main body 202. The connecting portion 203 is straight or curved. Specifically, a connecting portion 203 is provided between the first main body 201 and the second main body 202. When the atomized liquid is injected, the atomized liquid flows from the second oil tank 30 to the second main body 202, passes through the connecting portion 203, and then flows to the first main body 201, and finally flows to the first oil tank 10.

[0037] In some embodiments, the connecting portion 203 may be straight-through. It is understandable that the circulation of the atomized liquid between the first oil tank 10 and the second oil tank 30 is achieved by gravity potential energy. By setting the connecting portion 203 to be straight-through, the bending of the connecting portion 203 can be reduced, the unidirectional change of gravity potential energy can be ensured, and the smooth circulation of the atomized liquid can be ensured. At the same time, the difficulty of preparation can also be reduced.

[0038] In some embodiments, the connecting portion 203 may be curved, thereby appropriately slowing down the flow rate of the atomized liquid in the connecting portion 203 and preventing the atomized liquid from having a strong impact on the first blocking member 4 and the second blocking member 5 and damaging the first blocking member 4 and the second blocking member 5 or other structures.

[0039] For further information, see Figure 3-5The first main body 201 has a first opening 2011 connected to the connecting part 203. When the first blocking member 4 is a round ball, the radial size of the round ball is greater than the size of the first opening 2011. The second main body 202 has a second opening 2021 connected to the second oil tank 30. When the second blocking member 5 is a round ball, the radial size of the round ball is greater than the size of the second opening 2021. In the blocking state, the first blocking member 4 blocks the first opening 2011, and / or the second blocking member 5 blocks the second opening 2021.

[0040] In some specific embodiments, there are at least the following three blocking states between the first oil tank 10 and the second oil tank 20, as described below:

[0041] like Figure 3 As shown, in the first blocking state, the second blocking member 5 blocks the second opening 2021, and the atomized liquid in the second oil tank 30 cannot flow to the second main body 202 through the second opening 2021, and thus cannot flow to the connecting portion 203, and further cannot flow to the first main body 201 and the first oil tank 10; further, when the first blocking member 4 blocks the first opening 2011, the atomized liquid cannot flow from the connecting portion 203 to the first main body 201 through the first opening 2011, and thus cannot flow to the first oil tank 10. By blocking the first opening 2011 with the first blocking member 4 and the second opening 2021 with the second blocking member 5, a double sealing effect can be achieved, which further improves the air tightness in the blocking state and improves the anti-leakage effect;

[0042] like Figure 5 As shown, in the second blocking state, the first blocking member 4 blocks the first opening 2011, and the second blocking member 5 does not block the second opening 2021. Although the atomized liquid can flow from the second oil tank 30 to the first main body 201 and the connecting portion 203 through the second opening 2021, the first blocking member 4 blocks the first opening 2011, so that the atomized liquid cannot flow to the first oil tank 10 through the first opening 2011, and the sealing effect can also be achieved;

[0043] In the third blocking state, the first blocking member 4 does not block the first opening 2011, and the second blocking member 5 blocks the second opening 2021. The second blocking member 5 blocks the second opening 2021, so that the atomized liquid in the second oil tank 30 cannot flow to the second main body 202 through the second opening 2021. Therefore, although the first blocking member 4 does not block the first opening 2011, the atomized liquid still cannot flow to the first oil tank 10 in the end, and the sealing effect can also be achieved.

[0044] For further information, see Figure 3-5The first main body 201 has a first space 2012 at one end opposite to the first opening 2011, and the second main body 202 has a second space 2022 at one end opposite to the second opening 2021; in the open state, the first blocking member 4 is located in the first space 2012, and the second blocking member 5 is located in the second space 2022.

[0045] Specifically, Figure 4 As shown, in the process of changing from the blocking state to the open state, the atomized liquid flowing out of the second oil tank 30 pushes the second blocking member 5 at the second opening 2021 to the second space 2022 by gravity, thereby realizing the open state of the second blocking member 5 at the second opening 2021; the atomized liquid flows to the connecting portion 203 through the second opening 2021, and also by gravity, the atomized liquid in the connecting portion 203 pushes the first blocking member 4 at the first opening 2011 to the first space 2012, so that the first blocking member 4 realizes the open state at the first opening 2011. In addition, the first main body 201 is provided with a third opening 2013 connected to 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 be connected to the connecting portion 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, flow to the connecting part 203 through the fourth opening 2023, flow to the first main body 201 through the first opening 2011, and finally flow to the first oil tank 10 through the third opening 2013.

[0046] It can be understood that during the transition from the open state to the blocked state, the first blocking member 4 moves from the first space 2012 to the first opening 2011 by its own gravity; the second blocking member 5 moves from the second space 2022 to the second opening 2021 by its own gravity.

[0047] For further information, see Figure 3-5 The first main body 201 is provided with an anti-stuck structure at the position of the first space 2012 , and / or the second main body 202 is provided with a confluence portion 200 at the position of the second space 2022 and the connecting portion 203 .

[0048] In some embodiments, the first main body 201 may be provided with an anti-stuck structure at the position of the first space 2012, and specifically, the anti-stuck structure may be a protrusion protruding from the inner wall of the first main body 201. When the first blocking member 4 is pushed into the first space 2012, the protrusion may effectively prevent the first blocking member 4 from being stuck in the first space 2012, so that when the first blocking member 4 is transformed from the open state to the blocked state, the gravity of the first blocking member 4 may be prevented from being less than the clamping force and unable to be moved out of the first space 2012, thereby preventing the subsequent operation of the device from being affected.

[0049] In some embodiments, the anti-stuck structure may be an inclined surface disposed on the inner side of the first main body portion 201 , which may also prevent the first blocking member 4 from being stuck in the first space 2012 .

[0050] In some embodiments, a confluence portion 200 may be provided between the second main body 202 and the connecting portion 203, and the confluence portion 200 is provided at the position of the second space 2022 of the second main body 202. When the second blocking member 5 moves back and forth between the second opening 2021 and the second space 2022 to switch between the blocking state and the opening state, the fluid such as liquid or gas on the inner wall of the second main body 202 may squeeze the second blocking member 5, resulting in obstruction to the movement of the second blocking member 5. By providing the confluence portion 200 to connect the second main body 202 and the connecting portion 203, a circulating fluid circuit can be formed between the second main body 202 and the connecting portion 203, thereby reducing the obstruction of the fluid to the second blocking member 5.

[0051] In some embodiments, the first main body 201 is provided with a first air return groove connected to the connecting portion 203 at the position of the first space 2012, and the second main body 202 is provided with an anti-stuck structure at the position of the second space 2022, which can also prevent the first blocking member 4 from being stuck in the first space 2012 and the second blocking member 5 from being stuck in the second space 2022.

[0052] For further information, see Figure 3-5 The first main body 201, the connecting portion 203 and the second main body 202 are arranged in sequence along the axial direction of the electronic atomization device, and the extension direction of the first main body 201 and the extension direction of the second main body 202 are both at an angle to the axial direction.

[0053] In some specific embodiments, the first main body 201, the connecting portion 203 and the second main body 202 are arranged in sequence along the axial direction of the electronic atomization device. Figure 3 As shown, when the electronic atomization device is placed forward, the first main body 201 is located at the top, the second main body 202 is located at the bottom; the first oil tank 10 is located on the top of the second oil tank 30. Figure 4As shown, when the electronic atomization device is placed inverted, 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, if Figure 3 As shown, the first blocking state is the state when the electronic atomization device is placed forward, at this time, the first blocking member 4 relies on its own gravity to block the first opening 2011, and the second blocking member 5 relies on its own gravity to block the second opening 2021. It can be understood that at this time, the second oil tank 30 is located at the bottom of the first oil tank 10, so that the atomized liquid in the second oil tank 30 cannot flow to the first oil tank 10. Therefore, by setting the first blocking member 4 and the second blocking member 5, it is actually to prevent the atomized liquid in the first oil tank 10 from leaking to the second oil tank 30. The second blocking state and the third blocking state are the states when the electronic atomization device is placed flat, in which Figure 5 The flat state shown is the second blocking state, at which the first blocking member 4 blocks the first opening 2011 by its own gravity, and the second blocking member 5 does not block the second opening 2021; and the third blocking state can be Figure 5 The electronic atomization device is in a flat state after being rotated 180°. At this time, the first blocking member 4 does not block the first opening 2011, and the second blocking member 5 blocks the second opening 2021 by its own gravity.

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

[0056] It can be understood that to switch from the blocked state to the open state, it is only necessary to change the placement direction of the electronic atomizer device, and the electronic atomizer device is in the open state only when it is placed in reverse, that is, in an upside-down state. Therefore, when the electronic atomizer device is placed upright or flat for use, the electronic atomizer device is in the blocked state, which can ensure the sealing during use.

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

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

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

[0060] It should be noted that the embodiment of the utility model does not limit the number of sealing members and the structure of the fluid channel 20. In practical applications, the number of sealing members and the fluid channel 20 can be adjusted according to the settings of the first oil tank 10 and the second oil tank 30 to achieve a sealing effect.

[0061] For further information, see Figure 1 , Figure 2 and Figure 6 The electronic atomization device includes an oil cup 1, a connecting piece 2 and a liquid storage bottle 3. The oil cup 1 is provided with a first oil tank 10 and an atomization core 7. A fluid channel 20 is formed inside the connecting piece 2. The liquid storage bottle 3 forms a second oil tank 30. The oil cup 1 and the connecting piece 2 are fixedly assembled, and the liquid storage bottle 3 and the connecting piece 2 are detachably connected.

[0062] Specifically, the first oil tank 10 and the atomizing core 7 are arranged inside the oil cup 1, and the atomized liquid in the first oil tank 10 flows to the atomizing core 7, so that the atomized liquid is heated by the atomizing core 7 to form an aerosol for the user to inhale or use. The second oil tank 30 can be used as an external oil tank, formed on the liquid storage bottle 3. Therefore, in the actual process, the electronic atomizing device can be reused by replacing the liquid storage bottle 3. Compared with disposable products and cartridge-changing products, the replacement cost of the electronic atomizing device of the embodiment of the utility model is low, which is more in line with the concept of green environmental protection and can extend the service life of the device. In addition, the liquid storage bottle 3 can be in a conventional bottled form. During transportation, the liquid storage bottle 3 can be transported alone, and the first oil tank 10 can be transported empty, so as to effectively prevent the atomized liquid in the first oil tank 10 from leaking to other components of the electronic atomizing device, and avoid leakage problems during transportation.

[0063] For further information, see Figure 2The first main body 201 has a third opening 2013 connected to the first oil tank 10. Along the axial direction of the electronic atomization device, the third opening 2013 is located on one side of the atomization core 7, and the direction from the third opening 2013 to the atomization core 7 is the same as the direction from the first oil tank 10 to the second oil tank 30.

[0064] Specifically, the atomized liquid can flow between the first oil tank 10 and the first main body 201 through the third opening 2013. When the electronic atomization device is placed forward, the first oil tank 10 is located above the second oil tank 30, so that the third opening 2013 is located above the atomization core 7. By arranging the third opening 2013 above the bottom of the first oil tank 10, when the electronic atomization device is placed forward, even if the first oil tank 10 flows back, it can be ensured that a certain amount of atomized liquid is stored in the first oil tank 10, thereby preventing the atomization core 7 from drying out.

[0065] Furthermore, the connector 2 includes a first portion 21 and a second portion 22, wherein the first portion 21 is close to the oil cup 1 and is integrally formed with the oil cup 1, and the first portion 21 and the second portion 22 can be sealed by ultrasonic welding. A portion of the fluid channel 20 is disposed in the first portion 21, and another portion of the fluid channel 20 is disposed in the second portion 22, that is, the first portion 21 and the second portion 22 together form the fluid channel 20, which facilitates the processing of the fluid channel 20.

[0066] It should be noted that the first main body 201 , the second main body 202 , the connecting portion 203 , the confluence portion 200 and the like in the fluid channel 20 are partially disposed in the first portion 21 , and the other part is disposed in the second portion 22 .

[0067] Furthermore, one of the first part 21 and the second part 22 is made of a hard material, and the other can be made of a soft rubber material, so that the two can be sealed in a detachable socket-fitting manner. When the sealing part in the fluid channel 20 is aged, it can be disassembled for maintenance or replacement.

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

[0069] For further information, see Figure 6The electronic atomization device also includes 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 wall of the first interface end and the inner wall of the second interface end, and at least one of the sealing member 6, the first interface end and the second interface end is provided with a first return air groove 300 connecting the outside and the second oil tank 30.

[0070] Specifically, the seal 6 can be a silicone member. The seal 6 can realize the sealing connection between the first interface end and the second interface end, so as to realize the sealing of the connection between the connector 2 and the liquid storage bottle 3. Therefore, when the electronic atomization device is placed forward, flat or reversely, the leakage problem can be avoided. In addition, the assembly connection of the connector 2 and the liquid storage bottle 3 can be realized through the first interface end, the seal and the second interface end, which has the effect of convenient operation. In addition, by opening the first return air groove 300, when the electronic atomization device is placed reversely, the atomized liquid is filled from the second oil tank 30 to the first oil tank 10, as the atomized liquid in the second oil tank 30 decreases, the pressure in the second oil tank 30 will become smaller, and due to the internal and external pressure difference, the external gas will be prompted to enter the second oil tank 30 through the first return air groove 300 to balance the air pressure.

[0071] As an example, a first air return groove 300 is formed between the seal 6 and the outer side wall of the first interface end; and / or a first air return groove 300 is formed between the seal 6 and the inner side wall of the second interface end.

[0072] For further information, see Figure 6 An inwardly folded flange 61 is provided at one end of the sealing member 6 close to the liquid storage bottle 3 .

[0073] Specifically, the sealing member 6 may be an annular columnar structure, and an inwardly folded edge is provided at one end of the sealing member 6 close to the liquid storage bottle 3, thereby ensuring that the atomized liquid cannot flow out through the first air return groove 300, thereby avoiding liquid leakage.

[0074] Furthermore, the oil cup 1 is provided with a bracket for assembling the atomizer core 7, and the bracket is provided with a second air return groove, and the second air return groove is used for ventilation when the electronic atomization device is working. At the same time, when the electronic atomization device is placed in reverse and oil is filled into the first oil tank 10, the gas in the first oil tank 10 can be discharged to the outside through the second air return groove.
