Description

Technical Field

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

[0002] An electronic atomizing device is a device that uses heating to act on an aerosol-generating product, thereby producing an aerosol for the user to inhale. Most electronic atomizing devices consist of an atomizing coil and a liquid reservoir. The liquid reservoir is used to store the aerosol-generating product, and the atomizing coil is connected to the liquid reservoir.

[0003] However, in existing electronic atomizing devices, the aerosol generated product in the liquid storage tank flows directly onto the atomizing core. When the electronic atomizing device is left for too long or is in a low-pressure environment, the aerosol generated product is prone to seeping out from the atomizing core. The seeping aerosol generated product leaks onto the PCBA, battery and other components inside the electronic atomizing device, causing the components to fail and thus adversely affecting the function of the electronic atomizing device. Utility Model Content

[0004] Therefore, it is necessary to provide an electronic atomization device that can prevent aerosol-generated products from leaking from the atomizing core, in order to address the above problems.

[0005] An electronic atomizing device, the electronic atomizing device comprising:

[0006] The housing has a receiving cavity, and the receiving cavity is provided with a liquid storage tank for storing aerosol-generated products;

[0007] An atomizing mechanism is disposed in the accommodating cavity and communicates with the liquid storage tank. The atomizing mechanism includes an atomizing component and a buffer component. The buffer component is disposed between the liquid storage tank and the atomizing component, and the buffer component is at least used to allow the aerosol generating product to pass through and reduce the flow rate of the aerosol generating product.

[0008] Furthermore, the buffer assembly includes a buffer member and a stop member. The buffer member is disposed on the side of the atomizing assembly near the liquid storage chamber to allow the aerosol generating article to pass through and reduce the flow velocity of the aerosol generating article. The stop member surrounds at least a portion of the outer peripheral side of the buffer member and extends toward the liquid storage chamber.

[0009] Furthermore, the buffer includes a buffer sheet with a through hole that communicates with the atomizing component.

[0010] Furthermore, the buffer sheet comprises multiple sheets, which are stacked sequentially along the height direction of the housing, and the projections of the through holes on two adjacent buffer sheets at least partially overlap within the projection along the height direction of the housing.

[0011] Furthermore, the through holes include at least one row. When the through holes include multiple rows, the multiple rows of through holes are spaced apart along the width direction of the buffer sheet, and each row of through holes includes at least one through hole.

[0012] Furthermore, the diameter D of the through hole satisfies the relationship: 1mm ≤ D ≤ 3mm; and / or,

[0013] The buffer sheet is selected from steel sheet, plastic sheet, gold sheet, silver sheet, copper sheet, iron sheet or tin sheet.

[0014] Furthermore, the atomizing mechanism includes a bracket with a mounting cavity. The atomizing component and the buffer component are both disposed within the mounting cavity. The atomizing component includes an atomizing core and a heating element. The buffer component is disposed on the side of the atomizing core near the liquid storage chamber. The heating element contacts the atomizing core to transfer the generated heat to the atomizing core.

[0015] Furthermore, a power source is provided within the accommodating cavity, and the heating element is located on the side of the atomizing core away from the liquid storage chamber. The heating element includes a contact plate, a contact pin, and a heating wire. The contact plate is connected to the heating wire, and both the contact plate and the heating wire are in contact with the atomizing core. The contact pin extends away from the atomizing core and connects between the power source and the contact plate. The support has a first clearance channel for the contact pin to pass through; and / or,

[0016] The atomizing core includes a ceramic atomizing core or a mesh cotton atomizing core.

[0017] Furthermore, a connection is provided between the buffer assembly and the liquid storage tank, and the connection is provided with at least one liquid flow channel and at least one gas flow channel. One end of the liquid flow channel is connected to the liquid storage tank, and the other end of the liquid flow channel is connected to the atomizing assembly.

[0018] The housing is provided with a suction nozzle, and the gas flow channel is connected between the atomizing component and the suction nozzle.

[0019] Furthermore, a sealing element is provided between the connecting part and the liquid storage tank, and a second clearance channel is provided on the sealing element, which is correspondingly provided with the liquid flow channel.

[0020] In the aforementioned electronic atomizing device, the atomizing component is the core part, primarily converting the aerosol-generating product into an aerosol for easy inhalation. Because the buffer component in this application is located between the liquid storage chamber and the atomizing component, and the atomizing mechanism is connected to the liquid storage chamber, when the aerosol-generating product in the liquid storage chamber enters the atomizing mechanism, the buffer component prevents the rapidly flowing aerosol-generating product from directly impacting the atomizing component, thus extending its service life and alleviating the liquid pressure at the atomizing component. Meanwhile, because the buffer component has the function of reducing the flow rate of the aerosol product, when the aerosol product flows onto the buffer component, the buffer component can slow down the flow rate of the aerosol product, so that the aerosol product flows slowly onto the atomizing component. The atomizing component can more fully convert the aerosol product into an aerosol for the user to inhale, effectively preventing the aerosol product from leaking from the atomizing component due to prolonged placement or being in a low-pressure environment. This prevents damage to other components inside the housing due to leakage and effectively ensures the normal use of the electronic atomizing device. Attached Figure Description

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0037] As mentioned in the background section, in existing electronic atomizing devices, the aerosol-generated product in the reservoir flows directly onto the atomizing core. When the electronic atomizing device is left unused for an extended period or in a low-pressure environment, the aerosol-generated product can easily leak from the atomizing core, damaging the internal components and adversely affecting its function, thus reducing its lifespan. To address this, the inventors of this application have designed a novel electronic atomizing device that prevents aerosol leakage from the atomizing core. The electronic atomizing device of this application will be described in detail below with reference to the accompanying drawings.

[0038] See Figures 1 to 7 As shown, this application provides an electronic atomizing device, which includes a housing 10 and an atomizing mechanism 30.

[0039] The housing 10 has a receiving cavity 101, within which a storage tank 20 for storing the aerosol-generated product is disposed. An atomizing mechanism 30 is disposed in the receiving cavity 101 and communicates with the storage tank 20. The atomizing mechanism 30 includes an atomizing component 31 and a buffer component 32. The buffer component 32 is disposed between the storage tank 20 and the atomizing component 31, and the buffer component 32 is at least used to allow the aerosol-generated product to pass through and reduce the flow velocity of the aerosol-generated product. It should be noted that the aerosol-generated product in this application is a liquid.

[0040] In this embodiment, the atomizing component 31 is the core part of the electronic atomizing device. It mainly converts the aerosol-generating product into an aerosol, making it easier for the user to inhale. Since the buffer component 32 is located between the liquid storage tank 20 and the atomizing component 31, and the atomizing mechanism 30 is connected to the liquid storage tank 20, when the aerosol-generating product in the liquid storage tank 20 enters the atomizing mechanism 30, the buffer component 32 can prevent the rapidly flowing aerosol-generating product from directly impacting the atomizing component 31, thus extending its service life and alleviating the liquid pressure at the atomizing component 31. Meanwhile, since the buffer component 32 has the function of reducing the flow rate of the aerosol-generated product, when the aerosol-generated product flows onto the buffer component 32, the buffer component 32 can slow down the flow rate of the aerosol-generated product, so that the aerosol-generated product slowly flows onto the atomizing component 31. The atomizing component 31 can more fully convert the aerosol-generated product into an aerosol for the user to inhale, effectively preventing the aerosol-generated product from leaking from the atomizing component 31 due to prolonged placement or being in a low-pressure environment. This prevents damage to other components inside the housing 10 due to leakage and effectively ensures the normal use of the electronic atomizing device.

[0041] Further, see Figure 1 as well as Figure 3 As shown, the buffer assembly 32 in this embodiment includes a buffer member 321 and a stop member 322. The buffer member 321 is disposed on the side of the atomizing assembly 31 near the liquid storage tank 20 to at least allow the aerosol-generated product to pass through and reduce the flow velocity of the aerosol-generated product. The stop member 322 surrounds at least a portion of the outer peripheral side of the buffer member 321 and extends toward the liquid storage tank 20. Exemplarily, the "stop member 322" in this embodiment includes silicone or soft rubber, etc.

[0042] Specifically, since the buffer 321 is located on the side of the atomizing component 31 near the liquid storage tank 20, the buffer 321 can directly buffer the aerosol generating product flowing out of the liquid storage tank 20, effectively reducing the flow rate of the aerosol generating product. This allows the aerosol generating product to flow more smoothly and evenly to the atomizing component 31, avoiding uneven supply caused by excessive flow rate. This ensures the stability and continuity of the atomizing component 31 during the atomization process. Furthermore, by reducing the flow rate of the aerosol generating product through the buffer 321, the impact and wear of the aerosol generating product on the atomizing component 31 can be reduced, extending the service life of the atomizing component 31 and reducing the operating costs caused by frequent replacement of the atomizing component 31.

[0043] Combination Figure 1 as well as Figure 3 As shown, in this embodiment, the stop 322 surrounds at least part of the outer periphery of the buffer 321 and extends towards the liquid storage chamber 20. This guides and constrains the aerosol-generated product, allowing it to flow more concentratedly through the buffer 321 to the atomizing assembly 31. This prevents splashing or leakage of liquid during flow, effectively ensuring the accuracy and stability of the liquid flow path. Simultaneously, the cooperation between the stop 322 and the buffer 321 further optimizes the buffering process. The stop 322 can block some of the rapidly flowing aerosol-generated product, causing it to accumulate or slow down within the space formed by the stop 322 and the buffer 321 before slowly flowing to the atomizing assembly 31 through the buffer 321. This enhances the overall buffering effect and improves the control accuracy of the liquid flow rate. Furthermore, since the stop member 322 in this embodiment is disposed around at least part of the outer peripheral side of the buffer member 321, the stop member 322 can effectively prevent the aerosol generation product from leaking out from the buffer member 321, avoid leakage from damaging other components inside the electronic atomizing device, reduce safety risks such as short circuits and corrosion caused by leakage, and effectively improve the reliability and safety of the electronic atomizing device.

[0044] Further, see Figures 4 to 5 As shown, the buffer 321 in this embodiment includes a buffer sheet 323, and the buffer sheet 323 is provided with a through hole 324, which is connected to the atomizing component 31.

[0045] Specifically, the size and number of through holes 324 can precisely control the flow rate of the aerosol-generated product to the atomizing component 31, thereby ensuring that an appropriate amount of liquid enters the atomizing component 31 under different operating conditions. This avoids both insufficient atomization due to excessive flow and leakage at the atomizing component 31 caused by excessive liquid flow, while also preventing insufficient flow from affecting the atomization effect, thus ensuring the stability and consistency of the atomization process. In addition, the buffer sheet 323 in this embodiment serves as an isolation layer, preventing the aerosol-generated product from directly flowing onto the atomizing component 31 and impacting it, extending the service life of the atomizing component 31, and alleviating the liquid pressure at the atomizing component 31.

[0046] Further, see Figures 6 to 7 As shown, the buffer sheet 323 in this embodiment includes multiple sheets, which are stacked sequentially along the height direction of the housing 10. Furthermore, within the projection along the height direction of the housing 10, the projections of the through holes 324 on two adjacent buffer sheets 323 at least partially overlap. It should be noted that the "height direction of the housing 10" in this application refers to the attached... Figure 1 The direction indicated by the letter X in the middle.

[0047] It is worth noting that in this embodiment, "the projections of the through holes 324 on two adjacent buffer sheets 323 at least partially overlap" includes at least two of the following cases:

[0048] (1) The projections of the through holes 324 on the two buffer sheets 323 only partially overlap;

[0049] (2) The projections of the through holes 324 on the two buffer sheets 323 completely overlap.

[0050] Specifically, multiple buffer sheets 323 form a multi-stage buffering structure. As the aerosol-generated product flows from the storage chamber 20 to the atomizing component 31, it experiences a buffering effect each time it passes through a buffer sheet 323. Compared to a single-stage buffering formed by a single buffer sheet 323, multi-stage buffering can more effectively reduce the flow velocity of the aerosol-generated product, making the liquid flow smoother and reducing fluctuations and impacts. Simultaneously, since the projections of the through holes 324 on adjacent buffer sheets 323 in this embodiment at least partially overlap, the through holes 324 on adjacent buffer sheets 323 can form a smaller micro-hole 325, further reducing the liquid flow velocity when the liquid passes through this micro-hole 325. It is worth noting that since the through hole 324 on the buffer sheet 323 has a small diameter, the processing difficulty will increase when it is necessary to process through holes 324 with even smaller diameters. Therefore, in this embodiment, by making the projections of the through holes 324 on two adjacent buffer sheets 323 at least partially overlap, the overlapping part of the two through holes 324 can form a fine hole 325 with a smaller diameter, thereby reducing the processing difficulty of the through hole 324.

[0051] Optionally, the buffer sheet 323 in this embodiment can be set to two sheets, or to three or more sheets.

[0052] Further, see Figure 6 As shown, the through holes 324 in this embodiment include at least one row. When the through holes 324 include multiple rows, the multiple rows of through holes 324 are spaced apart along the width direction of the buffer sheet 323, and each row of through holes 324 includes at least one through hole 324. It should be noted that the "width direction of the buffer sheet 323" in this application refers to the attached... Figure 5 The direction indicated by the letter Y.

[0053] Specifically, when the through holes 324 are arranged in multiple rows at intervals along the width of the buffer sheet 323, the flow rate of the aerosol-generated product can be flexibly controlled by adjusting the number and size of each row of through holes 324 and the spacing between rows. The arrangement of multiple rows of through holes 324 also helps to make the flow rate of the aerosol-generated product on the buffer sheet 323 more uniform, avoiding the problem of uneven flow rate caused by liquid concentrating in a certain area. Meanwhile, in this embodiment, each row of through holes 324 includes at least one through hole 324. Even if one or more through holes 324 become blocked, the other through holes 324 can still ensure normal liquid flow, reducing the risk of the entire buffer assembly 32 or the atomizing device failing due to blockage of individual through holes 324. This redundant design improves the fault tolerance of the electronic atomizing device and enhances its stability and durability under different usage environments and conditions.

[0054] Optionally, in this embodiment, the through holes 324 can be configured as one row, or as two or more rows, wherein each row of through holes 324 may include one through hole 324, or may include two or more through holes 324. (Appendix to this application) Figure 6 The diagram shows the case where the through holes 324 are configured in three rows, with each row containing five or six through holes 324.

[0055] Furthermore, referring to the figure, the diameter D of the through hole 324 in this embodiment satisfies the relationship: 1mm≤D≤3mm. For example, D can be set to 1mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm, 2mm, 2.2mm, 2.4mm, 2.6mm, 2.8mm, 3mm, etc.

[0056] Specifically, when D is less than 1 mm, the diameter of the through hole 324 is small, and tiny impurities, particles, or flocculent matter caused by liquid quality changes in the aerosol-generated product can easily clog the through hole 324, preventing the liquid from flowing through the through hole 324 normally. In addition, the through hole 324 with an excessively small diameter will severely restrict the flow rate of the aerosol-generated product, resulting in insufficient liquid reaching the atomizing component 31 per unit time and reducing the atomization efficiency of the atomizing component 31. When D is greater than 3 mm, the aperture of the through hole 324 is large, resulting in less resistance to the aerosol-generated product when passing through the buffer sheet 323, making it difficult to effectively reduce the flow rate of the liquid.

[0057] Furthermore, in this embodiment, the buffer sheet 323 is selected from steel sheet, plastic sheet, gold sheet, silver sheet, copper sheet, iron sheet or tin sheet.

[0058] Specifically, because steel, gold, silver, copper, iron, and tin sheets possess excellent strength and hardness, as well as good thermal conductivity, when placed as buffer sheets 323 on the atomizing component 31, they can withstand significant liquid pressure and impact forces. Furthermore, they can rapidly dissipate heat during atomization, preventing localized overheating and effectively improving the stability and lifespan of the atomizing component 31. Plastic sheets, with their good flexibility and elasticity, can better adapt to the internal space and shape of the atomizing device. They can deform to a certain extent without breaking under external force, providing excellent cushioning and effectively reducing the risk of damage to the electronic atomizing device due to vibration or impact.

[0059] Further, see Figure 1 as well as Figure 3As shown, the atomizing mechanism 30 in this embodiment includes a bracket 33, which has a mounting cavity 331. The atomizing component 31 and the buffer component 32 are both disposed in the mounting cavity 331. The atomizing component 31 includes an atomizing core 311 and a heating element 312. The buffer component 32 is disposed on the side of the atomizing core 311 near the liquid storage chamber 20. The heating element 312 contacts the atomizing core 311 to transfer the generated heat to the atomizing core 311.

[0060] Specifically, the mounting cavity 331 provides a fixed space for the atomizing component 31 and the buffer component 32, protecting the internal components from external physical impacts and damage. It also precisely positions each component, ensuring accurate relative positioning and making the overall structure of the atomizing mechanism 30 compact and stable, guaranteeing the normal collaborative operation of all components. The buffer component 32 acts as a transition between the liquid storage chamber 20 and the atomizing core 311, allowing for a more stable and uniform supply of liquid to the atomizing core 311. The direct contact between the heating element 312 and the atomizing core 311 enables efficient heat transfer, allowing the atomizing core 311 to be heated quickly and evenly. This ensures that the liquid on the atomizing core 311 is rapidly heated and atomized, improving atomization efficiency and generating a large amount of fine aerosol in a short time to meet user needs.

[0061] Further, see Figure 1 as well as Figure 4 As shown, in this embodiment, a power supply 70 is provided in the accommodating cavity 101, and a heating element 312 is provided on the side of the atomizing core 311 away from the liquid storage chamber 20. The heating element 312 includes a contact plate 313, a contact pin 314, and a heating wire 315. The contact plate 313 is connected to the heating wire 315, and both the contact plate 313 and the heating wire 315 are attached to the atomizing core 311. The contact pin 314 extends in a direction away from the atomizing core 311 and connects between the power supply 70 and the contact plate 313. A first clearance channel 332 is provided on the bracket 33 for the contact pin 314 to pass through.

[0062] Specifically, the power supply 70 provides stable power to the heating element 312 to ensure that the heating wire 315 can generate heat. The placement of the heating wire 315 against the atomizing core 311 allows the heat generated by the heating wire 315 to be transferred more directly and efficiently to the atomizing core 311, ensuring uniform heating and improving atomization efficiency and user experience. Simultaneously, the connecting piece 313 connects to the heating wire 315 and is attached to the atomizing core 311. This provides a stable power connection to the heating wire 315, ensuring it can generate heat normally. Furthermore, the attachment method aids in heat dissipation, preventing damage to the atomizing core 311 due to localized overheating. The placement of the connecting pin 314 forms a stable electrical connection path, ensuring that current can be smoothly transmitted from the power supply 70 to the heating wire 315, providing the necessary energy and ensuring the stable operation of the heating element 312. In addition, the bracket 33 in this embodiment is provided with a first clearance channel 332, which provides an accurate positioning and passage path for the power connection pin 314, ensuring that the power connection pin 314 can be accurately connected between the power supply 70 and the power connection piece 313, avoiding misalignment, bending and other problems of the power connection pin 314 during installation, and effectively ensuring the stability of the electrical connection.

[0063] Optionally, the power-connecting pin 314 in this embodiment may include a plate-shaped pin or a column-shaped pin, etc. Any other variation of the concept under this application is within the protection scope of this application.

[0064] Furthermore, the atomizing core 311 in this embodiment includes a ceramic atomizing core or a mesh cotton core atomizing core.

[0065] Specifically, ceramic atomizing coils have a porous structure that allows for rapid absorption and storage of liquids. Simultaneously, the microporous structure of the ceramic atomizing coil enables the liquid to evaporate evenly when heated, producing finer aerosol particles and enhancing the user experience. Mesh-type cotton atomizing coils are typically made by combining a metal mesh (such as stainless steel) with cotton materials. The high thermal conductivity of the metal mesh quickly transfers heat to the cotton wick, while the cotton wick efficiently absorbs and transports the liquid, achieving rapid atomization.

[0066] Further, see Figure 3 As shown, in this embodiment, a connecting part 40 is provided between the buffer component 32 and the liquid storage tank 20. The connecting part 40 is provided with at least one liquid flow channel 41 and at least one gas flow channel 42. One end of the liquid flow channel 41 is connected to the liquid storage tank 20, and the other end of the liquid flow channel 41 is connected to the atomizing component 31. A suction nozzle 50 is provided on the housing 10, and the gas flow channel 42 is connected between the atomizing component 31 and the suction nozzle 50.

[0067] Specifically, in this embodiment, the liquid channel 41 and the gas channel 42 are integrated into the connecting part 40, achieving physical isolation between the liquid and gas paths to avoid mutual interference. At the same time, the compact layout helps to reduce the size of the electronic atomization device and improve portability. The liquid channel 41 delivers the aerosol-generated product in the liquid storage chamber 20 to the buffer plate 323. The liquid then flows through the through holes 324 or micro holes 325 on the buffer plate 323 to the atomizing core 311. The liquid channel 41 ensures a stable liquid supply and avoids uneven liquid supply caused by gravity or tilting, thereby reducing the risk of dry burning and improving atomization efficiency. After the atomizing core 311 atomizes the liquid inside itself to generate aerosol through the heating element 312, the aerosol is quickly delivered from the gas channel 42 to the mouthpiece 50, preventing the aerosol from stagnating or condensing in the mounting cavity 331.

[0068] Optionally, the liquid flow channel 41 in this embodiment can be one, two or more; the gas flow channel 42 in this embodiment can be one, two or more, and this application does not make specific limitations.

[0069] Further, see Figure 3 As shown, in this embodiment, a sealing element 60 is also provided between the connecting part 40 and the liquid storage tank 20. The sealing element 60 is provided with a second clearance channel 61, which is correspondingly provided with the liquid flow channel 41. Exemplarily, the sealing element 60 in this embodiment includes a structure such as silicone or soft rubber.

[0070] Specifically, in this embodiment, the sealing element 60 is tightly fitted between the connecting part 40 and the liquid storage tank 20, thereby forming a physical barrier between the two and preventing the liquid in the liquid storage tank 20 from seeping into the receiving cavity 101, thus avoiding pollution or safety hazards; the setting of the second avoidance channel 61 can ensure that the liquid is only transported to the atomizing component 31 through the preset flow channel, avoiding the liquid flow being blocked due to the complete sealing of the sealing element 60, and maintaining the liquid guiding efficiency.

[0071] As can be seen from the above embodiments, since the liquid storage tank 20 of this application is always connected to the atomizing mechanism 30, if no other components are provided between the atomizing core 311 in the atomizing component 31 and the liquid storage tank 20, the liquid in the liquid storage tank 20 will be in constant contact with the atomizing core 311. Over a long period of time, the liquid will seep out from the atomizing core 311 and affect the use of other components inside the device. Therefore, in this application, a buffer sheet 323 is provided between the atomizing component 31 and the liquid storage tank 20, which can prevent the liquid from directly impacting the atomizing core 311. At the same time, since the buffer sheet 323 is provided with a through hole 324, the liquid can slowly flow from the through hole 324 to the atomizing core 311, and the atomizing core 311 can fully convert the liquid into gas, effectively preventing liquid leakage. When the electronic atomizing device is actually used, the power supply 70 in the accommodating cavity 101 provides power to the heating element 312. The heating element 312 can transfer the generated heat to the atomizing core 311. The liquid on the atomizing core 311 will be atomized under the action of heat and flow from the gas flow channel 42 to the mouthpiece 50 so that the user can inhale.
