Description

Technical Field

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

[0002] An electronic atomizing device is an electronic product that mimics 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. The e-liquid in the tank is transferred to the heating element via absorbent cotton. When the user inhales, the internal heating element heats the e-liquid, causing it to evaporate into an aerosol. This aerosol, along with air, enters the airway and is inhaled into the user's mouth. The e-liquid outlet is usually sealed by absorbent cotton, which absorbs and stores the e-liquid before transferring it to the heating element within its own cavity. The force used by the absorbent cotton to seal the outlet comes solely from the pressure of the heating element. However, during manufacturing, due to processing and manufacturing errors, the absorbent cotton often fails to effectively seal the outlet, leading to e-liquid leakage. This results in lower product yield and inconsistent reliability. Utility Model Content

[0003] In view of this, this application aims to provide an atomizing component that improves the effectiveness of the absorbent cotton in sealing the oil outlet by optimizing the structure, thereby preventing e-liquid leakage and improving the production yield and reliability of the product.

[0004] This application provides an atomizing component, including:

[0005] The air pipe is used to separate the oil tank and the air passage, and an oil outlet is opened on the pipe wall;

[0006] The inner tube is used to be installed in the air passage and to house the heating element in the lumen. An oil outlet is provided on the tube wall.

[0007] The oil-absorbing cotton is sleeve-shaped and is used to be placed between the air tube and the inner tube. In its original state, the inner diameter of the oil-absorbing cotton is smaller than the outer diameter of the inner tube and the outer diameter is larger than the inner diameter of the air tube, so that after the oil-absorbing cotton is assembled between the air tube and the inner tube, it is interference-fitted with both the air tube and the inner tube.

[0008] In one possible implementation, the difference between the outer diameter of the oil-absorbing cotton and the inner diameter of the air tube is R1, and 0.5mm≤R1≤2mm; and / or, the difference between the inner diameter of the oil-absorbing cotton and the outer diameter of the inner tube is R2, and 0.5mm≤R2≤2mm.

[0009] In one possible implementation, the heating component includes an oil-guiding cotton and a heating element, the oil-guiding cotton wrapping around the heating element and positioned relative to the oil outlet to block the oil outlet.

[0010] In one possible implementation, the oil-absorbing cotton includes a first cotton body and a second cotton body nested inside and outside, the first cotton body and the second cotton body having different densities, so that the oil-absorbing cotton has a high-density cotton area and a low-density cotton area in the radial direction.

[0011] In one possible implementation, the oil-absorbing cotton includes a first cotton body, a second cotton body, and a third cotton body nested inside and outside in sequence. The density of the first cotton body and the third cotton body is higher than the density of the second cotton body, so that the region of the oil-absorbing cotton near the inner tube and the air tube in the radial direction is a high-density cotton area and the central region is a low-density cotton area.

[0012] In one possible implementation, a connecting plug is inserted into the top of the trachea, the bottom surface of the connecting plug having a protrusion, and the top of the oil-absorbing cotton abutting against the protrusion, so that the top of the oil-absorbing cotton is partially in contact with the connecting plug and partially spaced from the connecting plug.

[0013] In one possible implementation, the protrusion is annular, or at least two protrusions are distributed circumferentially along the connecting plug.

[0014] In one possible implementation, the end of the protrusion has a flat end face that abuts against the oil-absorbing cotton, and the diameter of the protrusion gradually decreases in the direction away from the connecting plug.

[0015] In one possible implementation, a connecting plug is inserted into the top of the trachea, and a liquid-absorbing cotton is disposed between the oil-absorbing cotton and the connecting plug, with the liquid-absorbing cotton separated from the oil-absorbing cotton by a separating ring.

[0016] This application also provides an electronic atomizing device, which includes a housing, a nozzle disposed at one end of the housing, and the atomizing assembly as described above, wherein:

[0017] The atomizing component is disposed inside the housing, and the housing and the air pipe form an oil reservoir, with the air pipe forming one side wall of the oil reservoir.

[0018] The atomizing component provided in this application has an oil-absorbing cotton placed between the air tube and the inner tube. After being assembled between the air tube and the inner tube, the oil-absorbing cotton is clamped and squeezed by the air tube and the inner tube, which can effectively fit the air tube and the inner tube, effectively blocking the oil outlet on the air tube and the oil passage on the inner tube. At the same time, after the oil-absorbing cotton is squeezed, the area of ​​the oil-absorbing cotton near the air tube and the inner tube will increase in density, thereby enhancing the oil-locking ability and further preventing oil from flowing along the tube wall into the airway and causing leakage. Since the oil-locking ability of the oil-absorbing cotton is increased only near the air tube and the inner tube, while the main body area in the middle remains basically unchanged, it can also ensure the effective delivery and transfer of e-liquid without affecting the delivery of e-liquid to the heating element.

[0019] As can be seen, the atomizing component provided in this application can effectively ensure that the oil-absorbing cotton can effectively seal the oil outlet and the oil passage after assembly, with strong oil-locking ability, solving the problem of e-liquid leakage, while not affecting the transmission of e-liquid to the heating component.

[0029] 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.

[0030] An electronic atomizing device is an electronic product that mimics the function of a cigarette. It operates using a chip and an airflow sensor. Specifically, when a user inhales, airflow is generated within the device's internal airway. The airflow sensor detects this airflow, or pressure change, and sends a signal to the control system. The control system then powers the battery to supply power to the heating element (usually a heating coil). The heating element heats the e-liquid, atomizing it into an aerosol. This aerosol is carried by the airflow within the airway and inhaled into the user's mouth, producing a sensation similar to smoking. The e-liquid is stored in a tank, which is typically separated from the airway by an air tube. The air tube has an outlet, and an absorbent pad is located inside the air tube, while the heating element is housed within the absorbent pad. The absorbent pad absorbs and stores the e-liquid from the outlet. Because the absorbent pad is in contact with the heating element, it transports the e-liquid to the heating element. When the heating element heats up, it heats the e-liquid transported from the absorbent pad, thus generating an aerosol. Because the absorbent cotton constantly needs to absorb e-liquid, the e-liquid outlet is usually sealed with it. The force with which the absorbent cotton seals the outlet typically relies on the squeezing force of the heating element (usually an elastic heating mesh placed inside the absorbent cotton, creating an outward-expanding effect). However, this force is relatively small. Furthermore, during manufacturing, significant processing errors or unstable assembly of the absorbent cotton can prevent a tight seal, allowing e-liquid to leak into the air tube and even down to the mouthpiece, resulting in leakage and negatively impacting the user experience.

[0031] Please refer to the attached document. Figures 1-7 The embodiments of this application provide an atomizing component that improves the effectiveness of the absorbent cotton 2 in sealing the oil outlet 101 by optimizing the structure, thereby preventing e-liquid leakage and improving the production yield and reliability of the product.

[0032] The atomizing assembly includes an air tube 1, an oil-absorbing cotton 2, and an inner tube 3. The air tube 1 separates the oil reservoir 6 from the air passage; that is, the air tube 1 forms the wall of the oil reservoir 6, and an oil outlet 101 communicating with the oil reservoir 6 is opened on the wall of the air tube 1. The cavity of the air tube 1 forms the air passage. The inner tube 3 is placed within the air passage and accommodates the heating element within its own cavity; that is, the inner tube 3 is placed within the cavity of the air tube 1, and the heating element is placed within the cavity of the inner tube 3. An oil outlet 301 is opened on the wall of the inner tube 3. The oil-absorbing cotton 2 is sleeve-shaped and is placed between the air tube 1 and the inner tube 3. In its initial state, the inner diameter of the oil-absorbing cotton 2 is smaller than the outer diameter of the inner tube 3, and its outer diameter is larger than the inner tube 3 diameter of the air tube 1. When the oil-absorbing cotton 2 is assembled between the air tube 1 and the inner tube 3, the oil-absorbing cotton 2 is press-fitted to both the air tube 1 and the inner tube 3, meaning the oil-absorbing cotton 2 will tightly adhere to the inner wall of the air tube 1 and the outer wall of the inner tube 3.

[0033] Due to the interference fit structure, after the absorbent cotton 2 is assembled between the air tube 1 and the inner tube 3, it will be clamped and squeezed by the air tube 1 and the inner tube 3, maintaining precise coaxiality with the air tube 1 and the inner tube 3, and tightly fitting the inner wall of the air tube 1 and the outer wall of the inner tube 3. It will not have gaps with the air tube 1 or the inner tube 3 due to processing errors or assembly errors, effectively sealing the oil outlet 101 on the air tube 1 and the oil passage 301 on the inner tube 3. At the same time, after the absorbent cotton 2 is squeezed, the areas of the absorbent cotton 2 near the air tube 1 and near the inner tube 3 will be more compact, with higher density and stronger capillary action, thereby enhancing the oil-locking ability, that is, the strong adsorption force of e-liquid, preventing e-liquid from flowing from the absorbent cotton 2 to other parts, and further preventing the oil from flowing along the tube wall into the airway and causing leakage. Meanwhile, since the oil-absorbing cotton 2 only increases its oil-locking ability near the air tube 1 and inner tube 3, while the main body area in the middle remains basically unchanged, it can ensure the effective delivery and transfer of e-liquid without affecting the delivery of e-liquid to the heating element.

[0034] As can be seen, the atomizing component provided in this application can effectively ensure that the oil-absorbing cotton 2 can effectively seal the oil outlet 101 and the oil passage 301 after assembly, with strong oil-locking ability, solving the problem of e-liquid leakage, while not affecting the transmission of e-liquid to the heating component.

[0035] The absorbent cotton 2 absorbs e-liquid from the outlet 101 and then transfers it to the heating element through the outlet 301. Specifically, the heating element includes an absorbent cotton 4 and a heating element 5. The absorbent cotton 4 is positioned between the heating element 5 and the inner tube 3, wrapping around the heating element 5 and sealing the outlet 301 from the cavity of the inner tube 3. The absorbent cotton 4 absorbs e-liquid from the absorbent cotton 2 through the outlet 301 and then transfers it to the heating element 5, allowing the heating element 5 to have a large contact area with the e-liquid and increasing the amount of aerosol formed.

[0036] Specifically, such as Figure 3 As shown, the difference between the outer diameter of the oil-absorbing cotton 2 and the inner diameter of the air tube 3 of the air tube 1 is R1, where 0.5mm ≤ R1 ≤ 2mm. Verification shows that when the interference fit between the oil-absorbing cotton 2 and the outer tube is between 0.5-2mm, the effects of processing and assembly errors can be avoided, effectively ensuring a close fit between the oil-absorbing cotton 2 and the inner tube 3, while not excessively affecting the efficiency of the oil-absorbing cotton 2 in delivering e-liquid.

[0037] Similarly, such as Figure 3 As shown, the difference between the inner diameter of the oil-absorbing cotton 2 and the outer diameter of the inner tube 3 is R2, and 0.5mm≤R2≤2mm. When the interference fit or amount between the oil-absorbing cotton 2 and the inner tube 3 is 0.5-2mm, the influence of processing errors and assembly errors can be avoided, effectively ensuring the close fit between the oil-absorbing cotton 2 and the inner tube 3, while not excessively affecting the efficiency of the oil-absorbing cotton 2 in transporting e-liquid.

[0038] Preferably, the difference between the outer diameter of the oil-absorbing cotton 2 and the inner diameter of the air tube 3 of the air tube 1 is R1, and 0.8mm≤R1≤1.2mm; for example, R1 is 0.9mm, 1mm, 1.1mm, etc.

[0039] Preferably, the difference between the inner diameter of the oil-absorbing cotton 2 and the outer diameter of the inner tube 3 is R2, and 0.8mm≤R2≤1.2mm; for example, R2 is 0.9mm, 1mm, 1.1mm, etc.

[0040] Oil-absorbing cotton 2 can specifically be a one-piece cotton.

[0041] The oil-absorbing cotton 2 can be a single integral component, or the oil-absorbing cotton 2 can include at least two nested cotton bodies.

[0042] For example, the oil-absorbing cotton 2 includes a first cotton body 21 and a second cotton body 22 nested inside and outside. The first cotton body 21 and the second cotton body 22 have different densities, so that the oil-absorbing cotton 2 has high-density cotton areas and low-density cotton areas in the radial direction. In this way, the area where the oil-absorbing cotton 2 contacts the air tube 1, or the area where it contacts the inner tube 3, will not only fit snugly against the air tube 1 or the outer tube, but also has a relatively high density and strong oil-locking ability, which can further and thoroughly eliminate the problem of e-liquid leakage at the oil-absorbing cotton 2 caused by the production and assembly problems of the oil-absorbing cotton 2, air tube 1, and inner tube 3.

[0043] Preferably, such as Figure 5 As shown, the oil-absorbing cotton 2 includes a first cotton body 21, a second cotton body 22, and a third cotton body 23 nested sequentially. The density of the first cotton body 21 and the third cotton body 23 is higher than that of the second cotton body 22, so that the area of ​​the oil-absorbing cotton 2 near the inner tube 3 and the air tube 1 in the radial direction is a high-density cotton area, while the central area is a low-density cotton area. With this arrangement, the oil-absorbing cotton 2, composed of three cotton bodies with different densities nested together, has a strong oil-locking ability while maintaining a suitable e-liquid transmission capacity, without affecting the heating element 5's heating of the e-liquid or the formation of aerosol.

[0044] like Figure 6 As shown, a connecting plug 7 is inserted into the top of the air tube 1. The connecting plug 7 is cylindrical and is used to connect the nozzle and the airway. Inside the lumen of the air tube 1, the tip of the oil-absorbing cotton 2 can be spaced apart from the connecting plug 7. However, in some embodiments, to enhance the oil-absorbing cotton 2's oil-holding capacity and oil storage capacity, the oil-absorbing cotton 2 is positioned closer to the connecting plug 7. In some embodiments, the tip of the oil-absorbing cotton 2 can be connected to the connecting plug 7; this also enhances the fixation of the oil-absorbing cotton 2.

[0045] However, when the tip of the absorbent cotton 2 can connect with the connecting plug 7, gaps can easily form between the tip of the absorbent cotton 2 and the connecting plug 7 due to processing and assembly errors. These small gaps act like capillary channels, attracting e-liquid and causing it to accumulate. Excessive e-liquid accumulation may lead to leakage. Therefore, if... Figure 6 and Figure 7 As shown in the embodiment of this application, the bottom surface of the connecting plug 7 has a protrusion 71, and the top end of the oil-absorbing cotton 2 abuts against the protrusion 71, so that the top end of the oil-absorbing cotton 2 is partially in contact with the connecting plug 7 and partially spaced from the connecting plug 7. This arrangement can increase the length of the oil-absorbing cotton 2, thereby increasing the oil storage capacity, and at the same time, it can increase the gap between the oil-absorbing cotton 2 and the connecting plug 7, avoiding the storage of e-liquid between them.

[0046] Specifically, the protrusion 71 may be annular, or at least two protrusions 71 may be distributed circumferentially along the connecting plug 7.

[0047] like Figure 7 As shown, the end of the protrusion 71 has a flat end face 701 that abuts against the oil-absorbing cotton 2, and the diameter of the protrusion 71 gradually decreases in the direction away from the connecting plug 7. This arrangement can stably abut against the oil-absorbing cotton 2, stabilize the oil-absorbing cotton 2 and maintain the gap between the connecting plug 7 and the oil-absorbing cotton 2, and maximize the gap space between the connecting plug 7 and the oil-absorbing cotton 2.

[0048] When a user stops vaping after using the electronic atomizer, a small amount of aerosol remains in the airway. The condensate formed after the aerosol condenses will adhere to the inner wall of the airway. When the user vapes again, it is easy to be inhaled into the mouth, affecting the user's vaping taste and user experience. With the increase of use, the amount of condensate increases. When the amount is too large, the condensate can also flow back into the circuit system through the airway, causing a short circuit in the electronic control system, resulting in safety issues such as self-starting or spontaneous combustion. The condensate may also flow from the mouthpiece to the outside of the shell through the airway, causing e-liquid to leak out and contaminate the storage area or leave the user's hands oily when handling it.

[0049] To address this issue, in some embodiments, the absorbent cotton 2 is not connected to the connecting plug 7. Instead, a liquid-absorbing cotton is positioned between the absorbent cotton 2 and the connecting plug 7, and this liquid-absorbing cotton is separated from the absorbent cotton 2 by a separator ring. This arrangement places the liquid-absorbing cotton close to the mouthpiece, effectively absorbing condensate within the airway and preventing condensate from being inhaled into the user's mouth. It also prevents condensate from flowing out of the mouthpiece or accumulating excessively and flowing back into the electrical system. Simultaneously, the separator ring prevents the absorbent cotton 2 from absorbing e-liquid, thus avoiding interference with the absorption and storage of condensate. Furthermore, the separator ring's cavity does not block the airway, allowing the aerosol generated at the heating element 5 to flow smoothly through the separator ring's cavity to the mouthpiece for inhalation.

[0050] This application also provides an electronic atomizing device, which includes a housing, a mouthpiece disposed at one end of the housing, and the atomizing component described in any of the above embodiments; wherein the atomizing component is disposed within the housing, and the housing and the air pipe 1 enclose an oil reservoir 6, with the air pipe 1 forming one side wall of the oil reservoir 6. Thus, this electronic atomizing device possesses the structure and beneficial effects described in any of the above embodiments, solving the problem of e-liquid leakage while ensuring normal delivery of e-liquid to the heating element 5, which will not be elaborated further here.
