Description

Technical Field

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

[0002] Many electronic atomizing devices on the market currently suffer from leakage problems, especially those with a capacity of 10ml or more. Leakage occurs to varying degrees during both transportation and use.

[0003] The main reason is that there is a certain pressure difference between the oil reservoir in the atomizer and the outside air. Therefore, when the outside air enters the oil reservoir, e-liquid will leak out. It will not be easy to leak oil until the internal and external air pressures are balanced, or the air pressure in the oil reservoir is slightly less than the outside air pressure. Therefore, there is an urgent need in the market for a design solution that can solve the problem of atomizer leakage. Utility Model Content

[0009] In some embodiments, the distance between the outer tube and the middle tube is greater than the distance between the middle tube and the inner tube, and the lengths of the outer tube, the middle tube, and the inner tube decrease sequentially in the axial direction.

[0010] In some embodiments, the length of the first liquid-absorbing element is greater than the length of the middle layer tube, and the length of the second liquid-absorbing element is less than the length of the middle layer tube;

[0011] The atomizing core also includes a glass fiber tube, which is sleeved inside the middle tube and connected to the second liquid-absorbing element. The top end of the glass fiber tube is not lower than the top end of the first liquid-absorbing element.

[0013] In some embodiments, the first seal includes a first shaft segment and a first tapered segment coaxially arranged. The first tapered segment is provided with a first outer guide surface and a first inner guide surface facing away from each other. The first outer guide surface is used to guide the outer tube to be sleeved on the outer wall surface of the first shaft segment, and the first inner guide surface is used to guide the middle tube to be sleeved on the inner wall surface of the first shaft segment.

[0014] The second seal includes a second shaft section and a second tapered section arranged coaxially. The second tapered section is provided with a second outer guide surface and a second inner guide surface facing away from each other. The second outer guide surface guides the middle layer tube to be sleeved on the outer wall surface of the second shaft section, and the second inner guide surface is used to guide the atomizing component to be sleeved on the inner wall surface of the second shaft section.

A first gap and a second gap are formed in the atomizing core for secondary liquid storage, rationally allocating the progressively larger storage space for the aerosol matrix supplied to the atomizing component. Furthermore, a first liquid-absorbing element is filled in the first gap, and a second liquid-absorbing element is filled in the second gap. This synergistically reduces liquid supply fluctuations, ensuring the continuity and stability of the atomization process. It also mitigates, to some extent, the impact of air pressure and hydraulic pressure within the liquid storage chamber on the atomizing component, significantly improving the atomizing core's resistance to air pressure and hydraulic pressure fluctuations. This effectively reduces the risk of leakage in the atomizing component caused by liquid fluctuations and significant changes in air and hydraulic pressure, thus lowering the overall leakage rate of the atomizer.

[0029] This application provides an electronic atomizing device 300, see reference. Figure 1 , Figure 1 This is a schematic diagram of an embodiment of the electronic atomizing device provided in this application.

[0030] The electronic atomizing device 300 includes a main unit 200 and an atomizer 100. The main unit 200 is connected to the atomizer 100 and supplies power to the atomizer 100.

[0031] The electronic atomizing device 300 can be used to atomize aerosol matrices such as e-liquid, medicinal liquid, or nutrient solution, that is, to atomize liquid aerosol matrices into aerosols for users to inhale. The main unit 200 can be detachably connected to the atomizer 100 and supply power to the atomizer 100, thus allowing the atomizer 100 to be replaced; alternatively, the main unit 200 and the atomizer 100 can be integrated into one unit and supply power to the atomizer 100. The atomizer 100 stores and atomizes the aerosol matrix to form an aerosol for the user to inhale.

[0032] The main unit 200 includes an electrically connected control element and a battery. The control element is also used to electrically connect to the atomizer 100 to identify the status information of the atomizer 100 and control the power supply to the atomizer 100 based on the identified status information.

[0033] See Figures 2 to 4 , Figure 2 yes Figure 1 The diagram shows a structural schematic of one embodiment of the atomizer in the electronic atomizing device. Figure 3 yes Figure 2 The diagram shows the structure of the atomizing core in the atomizer. Figure 4 Is it like this? Figure 3 The diagram shows the exploded structure of the atomizer core.

[0034] like Figures 2 to 4 As shown, the atomizer 100 includes a housing assembly 10 and an atomizing core 20. The atomizing core 20 is connected to the housing assembly 10 and together they define a liquid storage chamber 101, which is used to store the aerosol matrix to be atomized. The atomizing core 20 is located inside the housing assembly 10 and atomizes the aerosol matrix by heating it. The housing assembly 10 is provided with an air inlet 102 and a mouthpiece 103. The air inlet 102 is used to introduce air into the atomizer 20, and the mouthpiece 103 is used to discharge the atomized aerosol.

[0035] Specifically, the housing assembly 10 includes a housing 12 and a base 14. One end of the housing 12 has a nozzle 103, and the other end is an open end. The base 14 is sealed to the open end of the housing 12. The two ends of the atomizing core 20 are respectively connected to the base 14 and the nozzle 103 and are sealed together. The base 14 is provided with an air inlet 102, and the atomizing core 20 is connected to the air inlet 102 and the nozzle 103. The base 14, the housing 12 and the atomizing core 20 together define a liquid storage chamber 101. The atomizing core 20 draws liquid from the liquid storage chamber 101 and heats and atomizes it to generate an aerosol for user use.

[0036] In this embodiment, the atomizing core 20 includes an outer tube 21, a middle tube 22, and an atomizing component 23. The outer tube 21 is provided with a first liquid inlet 201. The middle tube 22 is sleeved inside the outer tube 21 and spaced apart from the outer tube 21. A first gap 211 is formed between the middle tube 22 and the outer tube 21. The middle tube 22 is provided with a second liquid inlet 202. The atomizing component 23 is sleeved inside the middle tube 22 and spaced apart from the middle tube 22. A second gap 222 is formed between the outer wall of the atomizing component 23 and the middle tube 22. The first gap 211 and the second gap 222 both constitute a space for storing aerosol matrix. The first liquid inlet 201 connects to the first gap 211, and the second liquid inlet 202 connects the first gap 211 and the second gap 222. Liquid is supplied to the atomizing component 23 from the aerosol matrix stored in the second gap 222.

[0037] The atomizing component 23 includes an inner tube 231 and an atomizing element 232 disposed inside the inner tube 231. The inner tube 231 is provided with a third liquid inlet 203. The atomizing element 232 covers the third liquid inlet 203. The third liquid inlet 203 is connected to the second gap 222 so that the aerosol matrix can be introduced into the atomizing element 232 through the third liquid inlet 203. After the atomizing element 232 is heated, it is atomized. The atomized aerosol is discharged through the inner tube 231 to the mouthpiece 103 for the user to inhale.

[0038] Optionally, the atomizing element 232 includes a porous substrate and a heating element. The porous substrate is also cylindrical and matches the inner wall of the inner tube 231. The porous substrate can be porous ceramic or porous glass, and the heating element can be an electrothermal film or a heating coating, etc. The porous structure of the porous substrate is conducive to the uniform distribution and rapid evaporation of the aerosol matrix, and the heating element can uniformly atomize the aerosol matrix conducted by the porous substrate. During operation, the synergistic effect of the porous substrate and the heating element ensures that the aerosol matrix achieves the ideal atomization effect in a very short time, thereby providing users with a smooth and comfortable inhalation experience.

[0039] In this embodiment, the atomizing element 232 includes a liquid guiding element and a heating element. The liquid guiding element is liquid guiding cotton or non-woven fabric, etc., and the liquid guiding element is cylindrical inside the inner tube. The heating element can be a resistance wire or a heating mesh, etc. The heating element is wrapped by the liquid guiding element to ensure uniform heating of the aerosol matrix.

[0040] In other words, the outer tube 21, the middle tube 22, and the inner tube 231 are nested together and spaced apart, forming a first gap 211 and a second gap 222 between adjacent tubes for liquid storage. The aerosol matrix in the liquid storage chamber 101 enters the first gap 211 through the first inlet hole 201, and the aerosol matrix in the first gap 211 enters the second gap 222 through the second inlet hole 202. Finally, it is introduced into the atomizing element 232 through the third inlet hole 203 to achieve efficient atomization.

[0041] In addition to the liquid storage in the liquid storage chamber 101, a first gap 211 and a second gap 222 are further formed in the atomizing core 20 for secondary liquid storage. This rationally allocates the storage space of the aerosol matrix supplied to the atomizing component 232 in stages, thereby reducing liquid supply fluctuations, ensuring the continuity and stability of the atomization process, and mitigating the impact of air pressure and hydraulic pressure in the liquid storage chamber 101 on the atomizing component 23 to a certain extent. This significantly improves the atomizing core 20's resistance to air pressure and hydraulic pressure fluctuations, effectively reducing the risk of leakage in the atomizing component 23 caused by liquid fluctuations and significant changes in air and hydraulic pressure, and reducing the overall leakage rate of the atomizer 100.

[0042] Meanwhile, the two-stage liquid storage design optimizes the flow path of the aerosol matrix, reduces liquid backflow and retention, improves atomization efficiency, ensures a stable aerosol concentration for each user's inhalation, and further enhances the continuity and comfort of the user experience.

[0043] Furthermore, the outer tube 21, the middle tube 22, and the inner tube 231 are all rigid tubes. Rigid tubes are not easily deformed and are easy to assemble. At the same time, they can stabilize the gap between adjacent tubes, that is, stabilize the liquid storage between adjacent tubes, which can further improve the stability of aerosol formation.

[0044] In this embodiment, the outer tube 21, the middle tube 22, and the inner tube 231 are all steel tubes. Steel tubes have a low cost and good corrosion resistance, mechanical strength, and property stability, which ensures the stability and reliability of the atomizing core 20 in long-term use. They can also avoid changes in the composition of the aerosol matrix caused by long-term immersion in the aerosol matrix, thereby maintaining the consistency of aerosol quality.

[0045] The high strength of the steel pipe facilitates the thinning of the walls of the outer tube 21, the middle tube 22 and the inner tube 231, reducing the overall weight and volume, which is beneficial for miniaturization and improving the portability of the atomizer 100.

[0046] Alternatively, the outer tube 21, the middle tube 22, and the inner tube 231 may be made of different materials, such as stainless steel for the inner tube 231, aluminum alloy for the middle tube 22, and plastic for the outer tube 21; or, the outer tube 21, the middle tube 22, and the inner tube 231 may all be made of plastic.

[0047] Furthermore, the distance between the outer tube 21 and the middle tube 22 is greater than the distance between the middle tube 22 and the outer wall of the atomizing component 23, and the lengths of the outer tube 21, the middle tube 22 and the outer wall of the atomizing component 23 decrease sequentially in the axial direction of the outer tube 21.

[0048] In other words, the distance between the outer tube 21 and the middle tube 22 is greater than the distance between the middle tube 22 and the inner tube 231. The lengths of the outer tube 21, the middle tube 22 and the inner tube 231 decrease sequentially along the axial direction of the outer tube 21, so that the first gap 211 has a relatively large liquid storage space, while the second gap 222 has a relatively small liquid storage space. When the aerosol matrix of the liquid storage chamber 101 is supplied to the atomizing component 23, it passes through the first gap 211 and the second gap 222 in sequence, forming a two-stage liquid storage and gradient liquid supply mode. The larger space of the first gap 211 can accommodate more aerosol matrix, ensuring sufficient and continuous liquid supply to the second gap 222, and initially reducing the additional pressure caused by liquid fluctuations in the liquid storage chamber 101. The smaller space of the second gap 222 is set around the atomizing component 23, which can precisely control the amount of aerosol matrix supplied to the atomizing component 23, and further reduce the impact of liquid fluctuations by utilizing its small space characteristics, reducing the risk of leakage in scenarios such as transportation or falling.

[0049] In this embodiment, the inlet area of ​​the second liquid inlet 202 is larger than that of the first liquid inlet 201. This is to reduce the impact of liquid fluctuations in the storage chamber 101 on the aerosol matrix stored in the first gap 211 by using the smaller area of ​​the first liquid inlet 201, thereby reducing the direct effect of pressure changes caused by liquid fluctuations on the atomizing component 23. Meanwhile, the larger area of ​​the second liquid inlet 202 can quickly replenish the aerosol matrix in the second gap 222, ensuring stable liquid supply, and can also appropriately further reduce the impact of liquid fluctuations in the first gap 211 on the aerosol matrix in the second gap 222.

[0050] In one embodiment, such as Figure 4 As shown, the first liquid inlet 201 is a circular hole, and the second liquid inlet 202 is a connecting groove. The diameter of the circular hole is smaller than the width of the connecting groove along the circumference of the middle layer tube 22, and the length of the connecting groove is greater than its width. The length of the connecting groove extends parallel to the axial direction of the middle layer tube 22 to form the first anti-leakage barrier. The structural dimensions and position of the first liquid inlet 201 effectively intercept liquid fluctuations and prevent leakage. The second liquid inlet 202 ensures that the aerosol matrix flows smoothly into the second gap 222 to maintain the stability of the liquid supply. At the same time, it can also intercept liquid fluctuations in the first gap 211.

[0051] In another embodiment, in conjunction with reference to Figure 4 and Figure 5 The first liquid inlet hole 201 is a strip-shaped hole distributed parallel to the axial direction of the outer tube 21, and the second liquid inlet hole 202 is a connecting groove. The length of the strip-shaped hole along the axial direction is greater than the length of the connecting groove, and the width of the strip-shaped hole along the circumference of the outer tube 21 is less than the width of the connecting groove along the circumference of the middle tube 22.

[0052] In other words, the strip-shaped orifice is relatively long and narrow, while the connecting groove is relatively short and wide. The strip-shaped orifice effectively disperses liquid fluctuations and reduces the risk of leakage, while the connecting groove accelerates the flow of the aerosol matrix and ensures precise liquid supply. The ingenious combination of the strip-shaped orifice and the connecting groove optimizes liquid fluctuation control and improves liquid supply efficiency, achieving a balance between leak prevention and stable liquid supply, and ensuring high efficiency and safety in the atomization process.

[0053] Among them, there are multiple first liquid inlet holes 201 evenly distributed around the outer tube 21, and the diameter or groove width of the first liquid inlet holes 201 is 0.6-1.2mm; there are multiple second liquid inlet holes 202 evenly distributed around the middle tube 22, and the groove width of the second liquid inlet holes 202 is 2-10mm.

[0054] Specifically, the diameter or groove width of the first liquid inlet 201 can be 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.1mm or 1.2mm, etc., and the groove width of the second liquid inlet 202 can be 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, etc. These dimensional designs not only ensure that liquid fluctuations are effectively controlled, but also avoid reducing the flow efficiency of the aerosol matrix.

[0055] Optionally, the ends of the outer tube 21, the middle tube 22 and the inner tube 231 can be installed on the same base to form a stable three-layer sleeve structure.

[0056] In this embodiment, the atomizing core 20 further includes a first sealing element 24 and a second sealing element 25. The first sealing element 24 is sealed between the outer tube 21 and the middle tube 22, and the second sealing element 25 is sealed between the middle tube 22 and the outer wall of the atomizing component 23. The double sealing structure enables the outer tube 21, the middle tube 22 and the inner tube 231 to form a stable three-layer sleeve structure, so as to maintain the stability of the first gap 211 and the second gap 222 and prevent the aerosol matrix stored in the first gap 211 and the second gap 222 from leaking.

[0057] The first sealing element 24 is disposed between the end of the outer tube 21 and the end of the middle tube 22, and the second sealing element 25 is disposed between the end of the middle tube 22 and the end of the atomizing component 23.

[0058] There can be two first sealing elements 24, which are respectively disposed between the two ends of the middle layer tube 22 and the outer layer tube 21 to prevent the aerosol matrix in the first gap 211 from leaking out. There can also be two second sealing elements 25, which are respectively disposed between the two ends of the middle layer tube 22 and the inner layer tube 231 to ensure that the aerosol matrix in the second gap 222 does not leak.

[0059] In this embodiment, there is one first sealing element 24 and one second sealing element 25. The first sealing element 24 is disposed between the bottom end of the outer tube 21 and the bottom end of the middle tube 22. The top ends of the outer tube 21 and the middle tube 22 can be sealed by the structure at the nozzle 103, or the top of the first gap 211 can be sealed with cotton or non-woven fabric. The probability of the aerosol matrix in the first gap 211 flowing to the top due to gravity is small. Sealing with cotton or non-woven fabric can also effectively prevent the aerosol matrix in the first gap 211 from leaking out. The second sealing element 25 is disposed between the bottom end of the middle tube 22 and the bottom end of the atomizing component 23. The top of the second gap 222 can also be sealed with tube body or cotton, non-woven fabric, etc., to ensure that the aerosol matrix in the second gap 222 does not leak out, while maintaining the sealing and stability of the overall structure.

[0060] Both the first seal 24 and the second seal 25 are made of elastic material to ensure good sealing performance under different temperatures and pressures, thereby effectively preventing leakage of the aerosol matrix under different environmental conditions.

[0061] Specifically, the first sealing element 24 includes a first shaft section 241 and a first tapered section 242 coaxially arranged. The first tapered section 242 is provided with a first outer guide surface and a first inner guide surface facing away from each other. The first outer guide surface is used to guide the outer layer tube 21 to be sleeved on the outer wall surface of the first shaft section 241, and the first inner guide surface is used to guide the middle layer tube 22 to be sleeved on the inner wall surface of the first shaft section 241. The second sealing element 25 includes a second shaft section 251 and a second tapered section 252 coaxially arranged. The second tapered section 252 is provided with a second outer guide surface and a second inner guide surface facing away from each other. The second outer guide surface guides the middle layer tube 22 to be sleeved on the outer wall surface of the second shaft section 251, and the second inner guide surface is used to guide the inner layer tube 231 of the atomizing component 23 to be sleeved on the inner wall surface of the second shaft section 251.

[0062] The first sealing element 24 and the second sealing element 25 have the same structural features but different dimensions. Both the outer guide surface and the inner guide surface are tapered slopes. By utilizing the guiding and centering effect of the tapered slopes, the outer tube 21, the middle tube 22 and the inner tube 231 are coaxially arranged, and the first gap 211 and the second gap 222 are kept stable. This effectively prevents leakage of the aerosol matrix in different environments and improves the overall sealing effect.

[0063] Furthermore, the atomizing core 20 also includes a first liquid-absorbing element 26 and a second liquid-absorbing element 27. The first liquid-absorbing element 26 is filled in the first gap 211 and is used to absorb the aerosol matrix in the first gap 211. The second liquid-absorbing element 27 is filled in the second gap 222 and is used to absorb the aerosol matrix in the second gap 222. The second liquid-absorbing element 27 includes an inner tube 231 and supplies liquid to the atomizing assembly 23 from the aerosol matrix stored in the second liquid-absorbing element 27.

[0064] Both the first liquid-absorbing element 26 and the second liquid-absorbing element 27 can be made of materials such as absorbent cotton or non-woven fabric. Their excellent liquid absorption performance ensures the effective storage of the aerosol matrix and can stably supply liquid to the atomizing component 23.

[0065] The first liquid suction element 26 and the second liquid suction element 27, through the aerosol matrix stored in the suction gap, can further weaken the liquid supply fluctuation, ensure the continuity and stability of the atomization process, and further resist the influence of air pressure and hydraulic pressure in the liquid storage chamber 101 on the atomizing component 23. This significantly improves the atomizing core 20's resistance to air pressure and hydraulic pressure fluctuations, effectively reducing the risk of leakage of the atomizing component 23 caused by liquid fluctuations and significant changes in air and hydraulic pressure, and reducing the overall leakage rate of the atomizer 100.

[0066] Along the axial direction of the middle layer tube 22, the length of the first liquid-absorbing element 26 is greater than the length of the second liquid-absorbing element 27. The first liquid-absorbing element 26 can store more aerosol matrix, so that the first gap 211 has enough aerosol matrix to supply liquid to the second gap 222, thereby maintaining a stable liquid supply capacity to the second gap 222 during long-term use. At the same time, the aerosol matrix in the liquid storage chamber 101 flows into the first gap 211 from the first liquid inlet 201. After the first liquid-absorbing element 26 is saturated, it conducts the aerosol matrix to the second liquid-absorbing element 27 in the second gap 222. When the first liquid-absorbing element 26 is saturated, a liquid film is formed on its surface, which can block or increase the aerosol flow resistance, thus improving the anti-leakage effect.

[0067] In addition, both the first liquid suction component 26 and the second liquid suction component 27 are tubular, so they are easy and quick to assemble and have low cost.

[0068] In this embodiment, the distance between the outer tube 21 and the middle tube 22 is greater than the distance between the middle tube 22 and the inner tube 231, and the lengths of the outer tube 21, the middle tube 22 and the inner tube 231 decrease sequentially in the axial direction.

[0069] The first liquid-absorbing element 26 wraps around the middle layer tube 22 and covers the first liquid inlet hole 201 and the second liquid inlet hole 202. In the axial direction, the length of the first liquid-absorbing element 26 is greater than the length of the inner layer tube 231. The second liquid-absorbing element 27 wraps around the inner layer tube 231 and covers the second liquid inlet hole 202 and the third liquid inlet hole 203. In the axial direction, the second liquid-absorbing element 27 does not exceed the top end of the inner layer tube 231.

[0070] The length of the first liquid-absorbing element 26 is greater than the length of the middle layer tube 22, and the length of the second liquid-absorbing element 27 is less than the length of the middle layer tube 22; the atomizing core 20 also includes a glass fiber tube 28, which is sleeved inside the middle layer tube 22 and connected to the second liquid-absorbing element 27, and the top end of the glass fiber tube 28 is not lower than the top end of the first liquid-absorbing element 26.

[0071] Unlike existing technologies, this application discloses an electronic atomizing device, an atomizer, and its atomizing core. A first gap and a second gap are formed in the atomizing core for secondary liquid storage, rationally allocating the progressively larger storage space for the aerosol matrix supplied to the atomizing component. Furthermore, a first liquid-absorbing element is filled in the first gap, and a second liquid-absorbing element is filled in the second gap. This synergistically reduces liquid supply fluctuations, ensuring the continuity and stability of the atomization process. It also mitigates, to some extent, the impact of air pressure and hydraulic pressure within the liquid storage chamber on the atomizing component, significantly improving the atomizing core's resistance to air pressure and hydraulic pressure fluctuations. This effectively reduces the risk of leakage in the atomizing component caused by liquid fluctuations and significant changes in air and hydraulic pressure, thus lowering the overall leakage rate of the atomizer.

Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
