Description

Technical field

[0001] The utility model relates to the technical field of electronic atomization devices, and in particular to an electronic atomization device. [Background Technology]

[0002] The structure of a traditional electronic atomization device usually includes several main components such as a battery, a shell, an atomization core assembly, an isolator and an atomization liquid storage chamber. The atomization core assembly is provided with a liquid inlet hole, and the isolator isolates the atomization liquid storage chamber from the liquid inlet hole to ensure that the atomization liquid will not accidentally flow into the atomization core assembly when the electronic atomization device is not activated, thereby effectively avoiding leakage problems.

[0003] However, it also has disadvantages, the most prominent of which is that when using the electronic atomization device, the user needs to pull out the isolation piece that isolates the atomization liquid storage chamber and the atomization core assembly to perform atomization. However, due to the complexity of the design, the user needs to spend a lot of effort to pull out the isolation piece fixed in the liquid storage chamber, which affects the user experience. [Utility Model Content]

[0016] The electronic atomization device provided in the embodiment of the present invention has an air guide column that can ensure that the mouthpiece hole remains dry during the user's sucking process, reducing the risk of backflow of atomized liquid and leakage from the mouthpiece hole in various postures. The tip on the air guide column acts as a mechanical puncture site. When the user pulls the lifting rod upward, the tip can easily puncture the fragile part connecting the lifting rod and the isolation piece, so that the lifting rod and the isolation piece are smoothly separated.

[0036] Please combine Figure 1 - Figure 4An embodiment of the present invention provides an electronic atomization device 100, comprising a shell 1 and an isolation assembly 2 arranged in the shell 1, the isolation assembly 2 comprising an isolation member 21 and a lifting rod 23 connected to the isolation member 21 via a breakable portion 22, a nozzle hole 11 is provided on the shell 1, at least part of the lifting rod 23 extends from the nozzle hole 11; an air guide column 12 is provided on the inner wall of the shell 1 corresponding to the nozzle hole 11, and a tip 121 is provided at one end of the air guide column 12 away from the nozzle hole 11 corresponding to the breakable portion 22.

[0037] It can be understood that the air guide column 12 can ensure that the nozzle hole 11 remains dry during the user's sucking process, reducing the risk of the atomized liquid flowing back and leaking from the nozzle hole 11 in various postures. The tip 121 on the air guide column 12 acts as a mechanical puncture site. When the user pulls the lifting rod 23 upward, the tip 121 can easily puncture the connection between the lifting rod 23 and the isolation member 21, so that the lifting rod 23 and the isolation member 21 are smoothly separated to achieve airway connectivity. The tip 121 can also serve as a positioning structure to ensure that the lifting rod 23 and the isolation member 21 are accurately docked and disconnected at a specific position to reduce the risk of misoperation. After the lifting rod 23 is disconnected from the isolation member 21, the lifting rod 23 can be detached from the nozzle hole 11, and the airway connecting the electronic atomization device 100 to the external environment is opened, and the user can inhale.

[0038] Specifically, see Figure 5 The tip 121 is set toward the side away from the nozzle hole 11 and at the distal end of the air guide column 12, and is precisely aligned with the fragile portion 22. It has sufficient hardness to ensure that it can effectively puncture the fragile portion 22, while also having a certain toughness to prevent breakage during operation. The length and diameter of the tip 121 are adapted to the setting of the fragile portion 22 to achieve the effect of completely penetrating the fragile portion 22.

[0039] Optionally, the tip 121 can be configured to be in the shape of a blade, a cone, or a hooked spike to improve the efficiency of puncture and reduce the force required for puncture, and the outer surface of the tip 121 can be processed to be smooth to reduce friction.

[0040] The air guide column 12 is connected to the nozzle hole 11. When the user operates the lifting rod 23 to move upward, the isolation piece 21 is driven to move upward, and the fragile part 22 between the lifting rod 23 and the isolation piece 21 also moves upward. The tip 121 then pierces the fragile part 22 to activate the conduction of the airway; after the tip 121 is pierced, the air guide column 12 is hollow and provided with an air flow channel to ensure that air from the external environment can enter the interior of the electronic atomization device 100, and also to ensure that the atomized steam that has been atomized in the atomization core assembly 3 can flow smoothly out to the external environment to avoid blockage.

[0041] Furthermore, the isolation member 21 is movably mounted on the air guide column 12 , and the end of the isolation member 21 facing the nozzle hole 11 is tightly connected to the end of the air guide column 12 away from the nozzle hole 11 , and the isolation member 21 can move on the air guide column 12 .

[0042] Specifically, the isolator 21 is arranged in a hollow tubular shape, and the tubular isolator 21 is movably mounted on the air guide column 12. The lifting rod 23 is also arranged in a tubular shape. One end of the lifting rod 23 extends out of the electronic atomization device 100 through the nozzle hole 11, and the other end is sequentially inserted into the air guide column 12 and the isolator 21 and connected to the breakable part 22.

[0043] Furthermore, a step 16 is provided on the outer wall of the air guide column 12 near the nozzle hole 11. The length L1 of the step 16 from the tip 121 is as follows: Figure 2 The length L1 shown in FIG. 1 is equal to or greater than the length L2 of the breakable portion 22 from the end face of the isolating member 21 facing the nozzle hole 11 (as shown in FIG. Figure 2 L2 shown).

[0044] It can be understood that the step 16 is located on the outer wall of the air guide column 12 and has a stepped shape, ensuring that the isolation member 21 can be effectively blocked when the lifting rod 23 moves upward, ensuring that the lifting rod 23 and the isolation member 21 are completely separated.

[0045] The distance L1 between the step 16 and the tip 121 (e.g. Figure 2 L1 shown in FIG) is greater than or equal to the length L2 between the breakable portion 22 and the end face of the spacer 21 (as shown in FIG). Figure 2 L2) as shown, ensure that the movement range of the isolation member 21 is sufficient for the fragile portion 22 to move toward the tip 121, and ensure that the fragile portion 22 has been punctured by the tip 121 before the step 16 blocks it.

[0046] Specifically, the tip 121 is arranged below the step 16, and the tip 121 is arranged at the end of the air guide column 12 away from the nozzle hole 11, and the tip 121 has a certain length L3 (such as Figure 3 As shown in L3), when the lifting rod 23 is not pulled, the tip 121 has already extended into the interior of the isolation member 21, and the isolation member 21 is movably mounted on the air guide column 12. The length L1 (as shown in FIG. Figure 2 The length L1 shown in FIG. 1 is greater than or equal to the length L2 between the breakable portion 22 and the end face of the isolating member 21 facing the nozzle hole 11 (as shown in FIG. Figure 2 L2) as shown, ensure that when the lifting rod 23 moves, the tip 121 can contact the isolation member 21 before the step 16, and the fragile portion 22 has been punctured before the step 16 blocks it. The fragile portion 22 is set at a position opposite to the tip 121.

[0047] Further, see Figure 1The outer surface of the lifting rod 23 is provided with an annular groove 231 .

[0048] It can be understood that the annular groove 231 provided on the outer surface of the lifting rod 23 makes the outer surface of the lifting rod 23 uneven, which increases the friction of the user's hand when pulling out the lifting rod 23 and reduces the risk of slipping. Especially in a humid or greasy environment, it can provide a more reliable grip and help the user better position the fingers when touching the lifting rod 23, serving as a visual and tactile guide for operation, making the use of the lifting rod 23 more intuitive.

[0049] Furthermore, when the user pulls the lifting rod 23, the annular groove 231 can make the force transmission more effective, ensuring that the tip 121 can smoothly pierce the fragile part 22 and start the air flow channel in the air guide column 12. The annular groove 231 is arranged in a circular ring shape and can be arranged at the end of the lifting rod 23, or it can be arranged throughout the outer surface of the lifting rod 23. The annular grooves 231 of different widths and depths can also be designed to adapt to different functions.

[0050] Furthermore, the electronic atomization device 100 also includes an atomization core assembly 3, and the isolation member 21 is movably mounted on the outside of the atomization core assembly 3. A liquid inlet hole 31 is provided on the side of the atomization core assembly 3 away from the nozzle hole 11. A liquid storage chamber 4 is formed between the isolation assembly 2 and the shell 1, and the isolation assembly 2 separates the liquid inlet hole 31 and the liquid storage chamber 4.

[0051] It can be understood that the isolation member 21 is movably mounted outside the atomizer core assembly 3, allowing the isolation member 21 to move within a specific range according to the operation of the lifting rod 23, thereby changing the opening state of the liquid inlet hole 31 and flexibly adjusting the inflow of liquid. When the isolation member 21 is subjected to force, it controls the flow of the atomized liquid to the liquid inlet hole 31, and adjusts the connection relationship between the atomized liquid and the atomizer core assembly 3 as needed, thereby enhancing the user's sense of control over the device. When no force is applied, the isolation member 21 isolates the atomized liquid and the atomizer core assembly 3, thereby preventing the atomizer core assembly 3 from being immersed in the atomized liquid before use, which may cause malfunctions or liquid from penetrating into electronic components.

[0052] Specifically, the isolation component 2 forms an independent space between the liquid inlet hole 31 and the liquid storage chamber 4 to prevent the atomized liquid from flowing directly from the liquid storage chamber 4 into the atomizer core. It also effectively isolates the atomized liquid from the electrical part to prevent short circuit problems caused by liquid leakage. The liquid storage chamber 4 can store a certain amount of atomized liquid.

[0053] The liquid inlet hole 31 is arranged below the liquid storage chamber 4, away from the side of the suction nozzle hole 11, and is linked to the moving mechanism of the isolation component 2. When the user pulls the lifting rod 23, the isolation component 2 moves upward, opening the liquid inlet hole 31, so that the atomized liquid can flow into the atomizer core component 3; when not in use, the isolation component 21 separates the liquid inlet hole 31 and the liquid storage chamber 4 to prevent the atomized liquid from entering the atomizer core component 3.

[0054] Further, see Figure 2 The electronic atomization device 100 further includes a movable bottom seal 5 , which is arranged on a side of the atomization core assembly 3 away from the nozzle hole 11 . A through hole 13 is formed on a side of the shell 1 away from the nozzle hole 11 , and the bottom seal 5 seals the through hole 13 .

[0055] It can be understood that the bottom seal 5 effectively closes the through hole 13 of the shell 1 away from the nozzle hole 11, and fits tightly with the through hole 13 to keep the electronic atomization device 100 dry and tidy, reducing the risk of short circuit. The bottom seal 5 is a movable bottom seal 5, which can be moved according to usage needs to adapt to different working conditions.

[0056] Specifically, the bottom seal 5 uses high-temperature resistant and corrosion-resistant materials, such as silicone or rubber, to ensure good sealing during long-term use; the bottom seal 5 can be annular or disc-shaped, and a multi-layer sealing structure can be set to enhance the mobility and airtightness of the bottom seal 5.

[0057] Furthermore, a connecting portion 51 is provided on the bottom seal 5, and a connecting hole 14 is provided on the side of the shell 1 away from the suction nozzle hole 11. When the bottom seal 5 is pushed toward the side close to the suction nozzle hole 11, the connecting portion 51 is locked into the connecting hole 14 to limit the position.

[0058] It can be understood that the mating connection between the connecting hole 14 and the connecting part 51 limits the range of movement of the bottom seal 5, avoiding excessive movement of the bottom seal 5, and the connection between the connecting hole 14 and the connecting part 51 enhances the structural stability; by limiting the movement of the bottom seal 5, the user can intuitively feel the working status of the bottom seal 5, and after pushing the bottom seal 5 to the connecting hole 14, there will be obvious feedback, letting the user know that the set operating limit has been reached.

[0059] Optionally, the connecting portion 51 can be a protruding buckle or pin, and the connecting hole 14 can be a corresponding groove, ensuring that the connecting portion 51 can be firmly inserted into the connecting hole 14 to form a stable connection; the bottom seal 5 and the shell 1 can also be connected in a pushable manner through a threaded, plug-in, sliding rail or magnetic connection design. In this embodiment, no specific limitation is made, as long as a movable connection between the bottom seal 5 and the shell 1 can be achieved.

[0060] Specifically, the connecting hole 14 is provided at a position at the bottom of the housing 1 away from the nozzle hole 11 , so that when the bottom sealing member 5 is pushed, the connecting portion 51 can dock smoothly and restrict its movement.

[0061] It can be understood that a spring mechanism can be added between the bottom seal 5 and the connecting part 51 to enhance the stability of the connection, while allowing the connecting part 51 to have a certain degree of flexibility when subjected to force, ensuring that the bottom seal 5 does not deviate excessively from the predetermined position during movement, forming a good seal and preventing liquid leakage.

[0062] For further information, see Figure 7 A residual liquid chamber 41 is formed between the shell 1 and the lowest point of the liquid inlet hole 31 on the side facing the bottom sealing member 5 .

[0063] Specifically, if Figure 7 The liquid inlet hole 31 is arranged on the outer wall surface of the atomizer core assembly 3. The lowest point of the liquid inlet hole 31 forms a step with a height difference with the atomizer core assembly 3. Figure 7 In the enlarged schematic diagram shown, the auxiliary line AA represents the extension line of the lowest point of the liquid inlet hole 31. The residual liquid chamber 41 is the space on the side of the extension line AA toward the bottom seal 5. The residual liquid chamber 41 is part of the liquid storage chamber 4. The atomized liquid in the residual liquid chamber 41 below the lowest point of the liquid inlet hole 31 will always be below the lowest point of the liquid inlet hole 31, and thus cannot enter the liquid inlet hole 31, and is difficult to be fully utilized.

[0064] Further, see Figure 3 - Figure 6 The electronic atomization device 100 further includes an annular seal 6 , which is disposed corresponding to the liquid inlet 31 and is disposed between the inner wall of the housing 1 and the atomization core assembly 3 .

[0065] Specifically, a residual liquid cavity 41 is formed between the lowest point of the liquid inlet hole 31 and the housing 1 on the side facing the bottom sealing member 5 .

[0066] Understandably, the atomized liquid in the residual liquid chamber 41 will always be below the lowest point of the liquid inlet hole 31, unable to enter the liquid inlet hole 31, and difficult to be utilized. One end of the annular seal 6 is located in the residual liquid chamber 41, which will occupy a portion of the space of the residual liquid chamber 41. The volume of the atomized liquid stored in the residual liquid chamber 41 is greatly reduced, and only a small portion of the atomized liquid is still stored in the residual liquid chamber 41 and cannot be utilized, thereby improving the utilization efficiency of the atomized liquid; and in the process of pushing the bottom seal 5 to drive the annular seal 6 to move, a certain compression force can also be given to part of the atomized liquid in the residual liquid chamber 41, which may promote the redistribution of the atomized liquid originally retained below the lowest point of the liquid inlet hole 31, thereby further improving the utilization efficiency of the atomized liquid.

[0067] Specifically, the annular seal 6 is set in a circular ring shape, which can fit tightly with the structure around the liquid inlet hole 31 and the atomizer core assembly 3, ensuring that the liquid in the liquid storage chamber 4 does not leak to other areas. It is made of high-temperature resistant and corrosion-resistant materials, such as silicone or rubber materials, to ensure that it maintains stable performance when immersed in the atomized liquid for a long time.

[0068] Furthermore, the annular seal 6 is fixedly connected to the atomizer core assembly 3, either by gluing or threading, to ensure a sealing effect; the annular seal 6 is movably connected to the housing 1 to push the bottom seal 5 to drive the annular seal 6 to move upward.

[0069] Specifically, when the bottom seal 5 is pushed, it drives the atomizer core assembly 3 and the annular seal 6 and other components to move inside the shell 1, further compressing the space of the liquid storage chamber 4. Therefore, the atomizer core assembly 3 can be designed as an integrated modular assembly, or the various components can be tightly connected to facilitate movement with the bottom seal 5 and the annular seal 6. The structural shape of the atomizer core assembly 3 should match the accommodating space formed inside the shell 1, and it should be set at the center of the electronic atomization device 100, tightly connected to the bottom seal 5 and the annular seal 6, to facilitate the inflow of liquid and the outflow of gas.

[0070] Furthermore, a liquid injection hole 15 is opened on the shell 1. When the bottom seal 5 is pushed to move, the bottom seal 5 drives the annular seal 6 to move toward the side close to the suction nozzle hole 11. When the connecting part 51 is locked into the connecting hole 14 to limit the position, the annular seal 6 seals the liquid injection hole 15.

[0071] It can be understood that by pushing the bottom seal 5, the annular seal 6 can be driven to move and seal the liquid injection hole 15: after the user completes adding liquid through the liquid injection hole 15, the bottom seal 5 is pushed to drive the annular seal 6 to move toward the side close to the suction nozzle hole 11. When the connecting part 51 is locked into the connecting hole 14 to limit the position, the liquid injection hole 15 originally connected to the liquid storage chamber 4 is blocked by the outer wall of the annular seal 6. The annular seal 6 seals the liquid injection hole 15, effectively preventing liquid leakage, simplifying operation, providing a good compression sealing effect, and helping to improve the stability of the overall equipment.

[0072] Specifically, if Figure 2 Cross-sectional view of the electronic atomization device 100 Figure 1 As well as Figure 5 The cross-sectional view of the electronic atomization device 100 is shown Figure 3 In the non-liquid-injected state, the bottom seal 5 partially extends out of the housing 1, the connecting portion 51 on the bottom seal 5 is not pushed into the connecting hole 14, the liquid inlet hole 31 and the liquid storage chamber 4 are separated by the isolation member 21, and the liquid injection hole 15 is connected to the liquid storage chamber 4; and as Figure 3 The cross-sectional view of the electronic atomization device 100 is shown Figure 2The injection is completed, and the lifting rod 23 in the isolation component 2 has been forced to drive the isolation member 21 to move a certain distance to the side of the suction nozzle hole 11. It can be seen that the injection hole 15 has been sealed and blocked by the annular seal 6, and the bottom seal 5 has completed the movement. The connecting part 51 on the bottom seal 5 has been pushed into the connecting hole 14, and the isolation member 21 exposes the liquid inlet hole 31, and the liquid inlet hole 31 is connected to the liquid storage chamber 4.

[0073] Specifically, the injection hole 15 cooperates with the moving mechanism of the annular seal 6. As an anti-backflow design of the injection hole 15, compared with sealing the injection hole 15 through an external component sealing plug, pushing the annular seal 6 to seal the injection hole 15 from the internal sealing plug can reduce the setting of components, facilitate operation and form an effective seal.

[0074] Further, see Figure 7 A guiding slope 61 is provided on one side of the annular seal 6 close to the liquid inlet hole 31 .

[0075] It can be understood that the guide slope 61 is provided on one side of the annular seal 6 close to the liquid inlet hole 31. The atomized liquid in the liquid storage chamber 4 can enter the liquid inlet hole 31 along the guide slope 61, and the guide slope 61 plays a guiding role; the guide slope 61 also helps the annular seal 6 to better fit the edge of the atomizer core assembly 3, enhance the sealing effect, prevent liquid leakage, and make it easier for the user to align the annular seal 6 during installation.

[0076] See also Figure 8 In an embodiment of the present invention, an electronic atomization device 100 further includes a power supply 7 , which is electrically connected to the atomization core assembly 3 to supply power to the atomization core assembly 3 .

[0077] Furthermore, the bottom seal 5 is located at the bottom of the electronic atomization device 100, close to the power supply 7. The bottom seal 5 is provided with a wire post 52 for accommodating the passage of a wire, and the power supply 7 is electrically connected to the atomization core assembly 3 through the wire.

[0078] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the principles of the present invention should be included in the scope of protection of the present invention.
