[0001] This application relates to the field of electronic atomization device technology, specifically to an atomization component and its electronic atomization device. Background Technology

[0002] An electronic atomizing device is an electronic product that mimics the function of a cigarette. It typically includes e-liquid stored in a tank, a heating element for heating the e-liquid, a circuit board, a battery, and an airway. When a user inhales from an electronic atomizing device, the internal heating element heats the e-liquid, causing it to evaporate into an aerosol. This aerosol is carried by air into the airway and inhaled by the user. However, when the user stops inhaling, some aerosol remains in the airway. This aerosol condenses and forms a condensate that adheres to the airway. With repeated inhalations, a significant amount of condensate accumulates in the airway. Some of this condensate is inhaled during the next inhalation, affecting the vaping experience. Furthermore, as this condensate accumulates, in severe cases, it can flow back onto the circuit board, causing a short circuit in the electronic control system, leading to automatic restart or spontaneous combustion. It may also flow out of the device, leaving the user's hands covered in e-liquid, further impacting the user experience. Summary of the Invention

[0014] In one possible implementation, a local section of the air pipe is provided with an oil-guiding sleeve that is fitted over the first oil-absorbing cotton. The oil-guiding sleeve is provided with a capillary oil passage extending along the axial direction.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] An electronic atomizing device is an electronic product that mimics the function of a cigarette. It operates by controlling its function through a chip and an airflow sensor. Specifically, the working principle of an electronic atomizing device is as follows: when the user inhales, airflow is generated within the air passage of the housing 1. The airflow sensor detects this airflow, or rather, the change in air pressure, and sends a signal to the control system. The control system then increases the power supply from the battery to the atomizing coil (usually including a heating wire). The atomizing coil heats the e-liquid (the wicking component draws e-liquid from the e-liquid tank 12 and delivers it to the atomizing coil), causing the e-liquid to atomize into an aerosol. This aerosol flows with the airflow within the air passage and is inhaled into the user's mouth, producing a sensation similar to smoking.

[0026] When the user stops inhaling, a small amount of aerosol matrix will remain in the airway inside the shell 1. The condensate formed after the aerosol condenses will adhere to the inner wall of the airway. When the user inhales again, it will be easily drawn into the mouth, affecting the user's inhalation taste and user experience. As the number of uses increases, the amount of condensate will increase. When the amount is too large, the condensate can easily flow back into the circuit system through the airway, causing a short circuit in the electronic control system, which may lead to safety issues such as self-starting or spontaneous combustion. The condensate may also flow from the mouthpiece 2 through the airway to the outside of the shell 1, causing e-liquid to leak out and contaminate the storage area or leave the user's hands oily when handling it.

[0027] In view of this, please refer to Figures 1-4. Embodiments of this application provide an atomizing component designed to solve the problem of condensation. This component can effectively absorb condensation without affecting airflow, improving the user's vaping experience, preventing condensation from flowing back into the circuit system or outside the electronic atomizing device, and solving many problems caused by excessive condensation buildup and spillage.

[0028] The atomizing assembly includes an air tube 5, a heating element 3, a first absorbent cotton 4, and a second absorbent cotton 6. The air tube 5 forms an airway, with its lower end connected to the air intake path that supplies air into the housing 1, and its upper end connected to the air path on the mouthpiece 2 (directional terms used in this application are based on the accompanying drawings; if the drawings are rotated, the directions will be adjusted accordingly), to deliver aerosol to the mouthpiece 2. The first absorbent cotton 4 is positioned between the oil tank 12 and the heating element 3, absorbing e-liquid from the outlet of the oil tank 12 and delivering it to the heating element 3. The heating element 3 is positioned within the airway (entirely or partially within the airway) and is used to heat the e-liquid to form an aerosol. The aerosol flows towards the mouthpiece 2 with the airflow within the airway. The second absorbent cotton 6 is positioned within the airway and between the heating element 3 and the airway outlet, with the second absorbent cotton 6 located on the side of the heating element 3 closer to the mouthpiece 2. Thus, the second absorbent cotton 6 is positioned close to the mouthpiece 2, effectively absorbing condensate and preventing it from being inhaled into the user's mouth. It also prevents excessive condensate from flowing out of the mouthpiece 2 or accumulating and flowing back into the electrical system. Simultaneously, the second absorbent cotton 6 is separated from the first absorbent cotton 4, preventing the second absorbent cotton 6 from absorbing e-liquid from the first absorbent cotton 4 and thus affecting its absorption and storage of condensate. Furthermore, the second absorbent cotton 6 has a first air passage 601, allowing aerosol to flow smoothly to the mouthpiece 2 during normal vaping, rather than being filtered by the second absorbent cotton 6 before reaching the mouthpiece 2. This avoids aerosol absorption affecting the taste, ensuring a superior vaping experience and flavor for the user.

[0029] As can be seen, the atomizing component provided in this application can effectively solve the problem of condensation and will not obstruct or filter the airflow during normal inhalation, thereby improving the inhalation experience; and avoids the problem of condensation backflow, improving safety and user experience.

[0030] Specifically, the second oil-absorbing cotton 6 can be sleeve-shaped with a central cavity; the outer wall of the second oil-absorbing cotton 6 is attached to the inner wall of the air tube 5, and the central cavity forms the first air passage 601. In this way, the second oil-absorbing cotton 6 is attached to the inner wall of the air passage, which can effectively absorb condensate, and the contact area with the inner wall of the air passage is large, which effectively avoids condensate residue.

[0031] Of course, the second absorbent cotton 6 can also be in other structural forms, such as including multiple cotton pads or cotton blocks, which are attached to the inner wall of the airway.

[0032] As shown in Figure 1, preferably, the first oil-absorbing cotton 4 is disposed inside the air tube 5. This allows the first oil-absorbing cotton 4 and the second oil-absorbing cotton 6 to completely cover the remaining inner wall of the air tube 5 (the area excluding the area occupied by necessary components such as seals or connectors), avoiding areas where condensate accumulates and facilitating complete absorption of condensate. The first oil-absorbing cotton 4 is also sleeve-shaped with a central cavity, forming a second air passage 401. The second oil-absorbing cotton 6 is located on the side of the first oil-absorbing cotton 4 closer to the nozzle 2 (i.e., above the first oil-absorbing cotton 4 in the attached figure). A partition 7 is provided between the second oil-absorbing cotton 6 and the first oil-absorbing cotton 4. The partition 7 separates the second oil-absorbing cotton 6 and the first oil-absorbing cotton 4 and provides a third air passage 701 that communicates with both the first air passage 601 and the second air passage 401. In this way, the first air passage 601, the third air passage 701, and the second air passage 401 are connected in sequence to form an actual suction air passage that is connected to the nozzle 2, allowing the supply air to flow quickly to the nozzle 2, thus ensuring the flow of aerosol during suction.

[0033] When the airflow carrying aerosol flows from the heating element 3 to the nozzle 2, it first passes through the first oil-absorbing cotton 4 and then the second oil-absorbing cotton 6. The location of the second oil-absorbing cotton 6 is also where condensate is more likely to form.

[0034] Meanwhile, the second absorbent cotton 6 and the first absorbent cotton 4 are separated by a partition 7, which prevents the second absorbent cotton 6 from absorbing the e-liquid on the first absorbent cotton 4. The independently designed partition 7 is also easy to process and assemble. Of course, in other embodiments, the second absorbent cotton 6 and the first absorbent cotton 4 can also be separated by a ring-shaped partition or partition protrusion integrally formed on the inner wall of the air tube 5.

[0035] As shown in Figure 1, further, the diameter of the third air passage 701 on the partition 7 is smaller than the diameter of the first air passage 601 and the diameter of the second air passage 401. This improves the separation effect of the partition 7 on the first absorbent cotton 4 and the second absorbent cotton 6; simultaneously, it prevents the airflow carrying aerosol from directly impacting the second absorbent cotton 6, avoiding the direct adsorption and retention of a large amount of aerosol in the vapor airflow on the second absorbent cotton 6, which would affect the taste; moreover, the narrowed third air passage 701 can constrict the airflow, forming a Venturi tube structure, where the airflow enters a wider section after passing through the narrow section, increasing the airflow speed, thereby further weakening the obstruction and adsorption effect of the second absorbent cotton 6 on the airflow, ensuring the density of aerosol in the airflow entering the user's mouth, and guaranteeing the user's inhalation experience.

[0036] Specifically, the partition 7 can be made of silicone or plastic, and it has a sealing plug structure with a central through hole. The outer wall of the partition 7 abuts against the inner wall of the air pipe 5, and the central through hole forms a third air passage 701. This not only facilitates the assembly of the partition 7, but also ensures a tight connection between the partition 7 and the inner wall of the air pipe 5, preventing gaps between the partition 7 and the inner wall of the air pipe 5 from causing the second absorbent cotton 6 to absorb the e-liquid from the first absorbent cotton 4 through the gaps.

[0037] As shown in Figure 3, in some embodiments, a convex ring 71 is provided on the outer wall of the partition 7, which protrudes radially and extends circumferentially; the convex ring 71 is provided as one or multiple rings spaced apart axially. By providing the convex ring 71, the tight contact between the partition 7 and the inner wall of the air pipe 5 can be enhanced, the sealing performance can be improved, and the e-liquid can be prevented from flowing from the gaps to the second oil-absorbing cotton 6.

[0038] A sealing sleeve 11 is provided at the outlet end of the air tube 5. The sealing sleeve 11 is used to fix the air outlet tube 21 on the nozzle 2, which is used to connect with the air passage. That is, after the nozzle 2 is connected to the housing 1, the air outlet tube 21 on the nozzle 2 will be inserted into the sealing sleeve 11 to achieve fixation with the housing 1 and communication with the air tube 5. One end of the second oil-absorbing cotton 6 abuts against the partition 7 and the other end abuts against the sealing sleeve 11. One end of the first oil-absorbing cotton 4 abuts against the partition 7 and the other end abuts against the base 10 of the atomizing core used to fix the heating element 3. In this way, not only are the components assembled stably, and there will be no shaking or misalignment during transportation or use that would affect adsorption, but the first oil-absorbing cotton 4, the partition 7, the second oil-absorbing cotton 6 and the sealing sleeve 11 can cover the entire inner wall of the air tube 5, avoiding leaving any empty areas, thereby effectively adsorbing all the condensate.

[0039] As shown in Figures 1 and 2, the air pipe 5 is provided with an oil inlet 501 for connecting with the oil tank 12. The first oil-absorbing cotton 4 covers all the oil inlets 501 to absorb the e-liquid and prevent the e-liquid from flowing to other areas and affecting normal use.

[0040] The heating element 3 is wrapped with oil-guiding cotton 9. A support tube 8 is provided between the oil-guiding cotton 9 and the first oil-absorbing cotton 4. The support tube 8 has multiple oil-permeable ports 801. The outer side of the oil-guiding cotton 9 contacts the first oil-absorbing cotton 4 through the oil-permeable ports 801 to transfer e-liquid to the heating element 3. The axial length of the first oil-absorbing cotton 4 is greater than the axial length of the oil-guiding cotton 9. The support tube 8 is provided inside the first oil-absorbing cotton 4 to enhance the support and compression of the first oil-absorbing cotton 4, thereby enhancing the oil absorption and locking capacity of the first oil-absorbing cotton 4 and preventing e-liquid from spreading. The heating element 3 and the support tube 8 can support and compress the oil-guiding cotton 9, ensuring the oil-locking capacity of the oil-guiding cotton 9 and preventing e-liquid from spreading. The first oil-absorbing cotton 4 covering the oil-guiding cotton 9 ensures that the e-liquid is transferred to the oil-guiding cotton 9 and then to the heating element 3.

[0041] When there is a lot of e-liquid in the oil tank 12, the pressure inside the oil tank 12 is less than the atmospheric pressure. The e-liquid can be normally absorbed by the first absorbent cotton 4 and flow out of the oil tank 12 without any leakage. When the amount of e-liquid in the oil tank 12 decreases to only a small amount, the pressure inside the oil tank 12 is relatively high, which can easily cause the e-liquid to flow out quickly, exceeding the oil-locking capacity of the first absorbent cotton 4 and spreading to other places, causing leakage.

[0042] To address this issue, in some embodiments, as shown in Figure 4, a local section of the air pipe 5 is provided with an oil-guiding sleeve 51. In other words, the air pipe 5 includes an axially arranged pipe body and an oil-guiding sleeve 51. The oil-guiding sleeve 51 is located outside the first oil-absorbing cotton 4, and the oil-guiding sleeve 51 has axially extending capillary oil passages 511. The capillary oil passages 511 have a capillary structure and are small tubes. The capillary oil passages 511 have a first oil inlet 512 and a second oil inlet 513, both of which are connected to the oil outlet of the oil tank 12 to absorb oil. And to transport e-liquid; in the axial direction of the oil inlet sleeve 51, the second oil inlet 513 is located on the side of the first oil inlet 512 near the mouthpiece 2 (in the attached figure, the second oil inlet 513 is located above the first oil inlet 512), and the second oil inlet 513 is close to and connected to the oil inlet hole 501 on the air pipe 5, that is, the distance between the second oil inlet 513 and the oil inlet hole 501 is less than the distance between the first oil inlet 512 and the oil inlet hole 501; for example, in the direction shown in the attached figure, the second oil inlet 513 can be basically flush with the oil inlet hole 501, while the first oil inlet 512 is located below both of them.

[0043] With this configuration, when there is a lot of e-liquid in the oil tank 12, for example, when the liquid level is higher than the second oil inlet 513, the e-liquid will enter the capillary oil path 511 simultaneously from the second oil inlet 513 and the first oil inlet 512, and flow to the oil inlet hole 501 where it will be absorbed by the first absorbent cotton 4, ensuring a normal e-liquid supply. When there is a little e-liquid in the oil tank 12, for example, when the liquid level is lower than the second oil inlet 513, the e-liquid can only enter the capillary oil path 511 from the first oil inlet 512, and then flow upwards against gravity towards the oil inlet hole 501, and then be absorbed by the first absorbent cotton 4 through the oil inlet hole 501. This structure of the capillary oil path 511 can slow down the e-liquid outflow speed and outflow pressure, making the outflow pressure of the e-liquid less than the oil-locking capacity of the first absorbent cotton 4, thereby preventing e-liquid leakage, while maintaining a continuous and normal e-liquid supply, and avoiding affecting normal use.

This electronic atomizing device possesses the structure and beneficial effects described in any of the above embodiments, solving the problem of condensation accumulation in the airway and further resolving the problem of e-liquid leakage when the e-liquid volume is low; further details will not be elaborated here.

[0045] Specifically, the electronic atomizing device includes a housing 1, a mouthpiece 2 disposed at one end of the housing 1, and an atomizing component as described above, wherein:

[0046] The housing 1 is also provided with an oil tank 12. The atomizing component is set in the oil tank 12, or rather inserted into the inner cavity of the oil tank 12.
