Abstract
Description
Technical Field
[0001] This application relates to the field of electronic atomization device technology, and in particular to a low-pressure leak-proof atomization device and its electronic cigarette. Background Technology
[0002] Electronic cigarettes (also known as "electronic cigarettes") are electronic delivery systems that use an atomizing core to generate an aerosol from an atomizing matrix for the user to inhale. The atomizing matrix can be a liquid (e.g., e-liquid, e-oil, etc.) or a solid or gel (e.g., e-cream paste).
[0003] To extend usage time, many e-cigarettes on the market now feature large e-liquid tanks. However, excessive e-liquid capacity leads to high pressure and rapid e-liquid delivery when the tank is full. This causes unvaporized e-liquid to leak, contaminating internal components and clogging airways, resulting in gurgling sounds when inhaled. Conversely, reducing the e-liquid inlet to slow delivery results in a slow supply as e-liquid levels decrease, posing a risk of dry burning. Therefore, there is an urgent need for an e-cigarette with a large tank, low leakage rate, and delivery speed less affected by e-liquid capacity. Summary of the Invention

[0017] This application also provides an electronic cigarette, including the aforementioned low-pressure leak-proof atomizing device and a power supply device for supplying power to the low-pressure leak-proof atomizing device.
[0018] In summary, the beneficial effects of this application are: 1. This application adopts a large oil tank with a large oil storage capacity; 2. The oil storage chamber is divided into upper and lower chambers by a partition and connected by an oil passage hole.

Therefore, unless indicated to the contrary, the numerical parameters listed in the following specification and appended claims are approximate values. They will vary for those skilled in the art depending on the desired properties and effects sought to be obtained through this disclosure, and each numerical parameter should be interpreted according to the number of significant figures and conventional rounding methods or in a manner understood by those skilled in the art.
[0040] In this disclosure, the terminology used in the description of the various examples is for the purpose of describing particular examples only and is not intended to be limiting. Unless the context explicitly indicates otherwise, an element may be one or more unless the number of elements is specifically limited. Furthermore, the term "and / or" as used in this disclosure covers any one of the listed items and all possible combinations thereof.
[0041] "Atomizing matrix" refers to a mixture or auxiliary substance that can be wholly or partially atomized into an aerosol by an electronic device or similar device. Atomizing matrix can be liquid forms such as e-cigarette liquids, e-liquids, e-creams, medical drugs, and skin lotions. By atomizing these media, an aerosol that can be inhaled or absorbed can be delivered to the user.
[0042] "Aerosol" refers to a colloidal dispersion system formed by small solid or liquid particles dispersed and suspended in a gaseous medium.
[0043] A "nebulizer" is a device that uses heat or ultrasound to form an aerosol from a stored atomizable substrate. The atomizing core is one of the main components of an atomizer.

In some examples, an e-cigarette may include an e-liquid reservoir for storing the atomizing substrate and an atomizing core for adsorbing and atomizing the atomizing substrate to form smoke.
[0045] In electronic cigarette technology, the atomizer core includes a heating element and an wicking component. The heating element heats the e-liquid to form vapor, while the wicking component guides the e-liquid from the reservoir surrounding the atomizer core to the heating element. The heating element can be made of a conductive, heated metal wire, and the wicking component can be made of cotton or fiber materials, with the heating element encased within it. Alternatively, the heating element can be made of a conductive, heated metal sheet, and the wicking component can be made of materials such as ceramic and can be formed as a hollow, sheet-like wicking component, with the heating element partially embedded in the inner wall of the wicking component.
[0046] The following description, in conjunction with the accompanying drawings, further illustrates this application:
[0047] See Figure 1-7 This embodiment provides an electronic cigarette, including a low-pressure leak-proof atomizing device 100 and a power supply device 200 for supplying power to the low-pressure leak-proof atomizing device 100. The low-pressure leak-proof atomizing device 100 includes an oil tank 10 and an atomizing coil 20. The power supply device 200 includes a battery cell for supplying power. The atomizing device 100 and the power supply device 200 can be detachably connected or fixedly connected.
[0048] like Figure 4 In some embodiments, one end of the oil tank body 10 is provided with a mouthpiece portion 14. The oil tank body 10 is provided with an oil storage chamber 15 for holding the atomizing matrix and an atomizing core 20 for absorbing and heating the atomizing matrix. The oil storage chamber 15 is provided with a partition 16 arranged laterally along the oil tank body 10. The partition 16 divides the oil storage chamber 15 into a first chamber 151 and a second chamber 152. The first chamber 151 and the second chamber 152 are arranged sequentially along the longitudinal direction of the oil tank body 10 from the end of the oil tank body 10 where the mouthpiece portion 14 is provided to the other end. The partition 16 is provided with an oil passage hole 17 that connects the first chamber 151 and the second chamber 152. The oil storage chamber 15 is divided into upper and lower chambers by the partition 16. The first chamber 151 and the second chamber 152 are connected by the oil passage 17. Moreover, the oil storage chamber 15 is only connected to the outside world through the atomizer core 20, so the sealing is relatively good. At the same time, since e-liquid is generally viscous, its surface tension is relatively high, which causes the e-liquid in the first chamber 151 to flow into the second chamber 152 through the oil passage 17 at a slow speed. When using some high-density e-liquid, the e-liquid in the first chamber 151 may not even flow into the second chamber 152 naturally under the action of gravity through the oil passage 17. It is necessary to shake it to make the e-liquid flow into the second chamber 152 through the oil passage 17. This greatly reduces the e-liquid pressure inside the second chamber 152 and avoids oil leakage from the atomizer core 20.
[0049] In some embodiments, the partition 16 is inclined, and the oil passage 17 is located at the lowest point of the partition 16; the inclined arrangement of the partition 16 facilitates the flow of e-liquid to the oil passage 17, which helps to make the e-liquid in the first chamber 151 fully utilized and avoids waste.
[0050] like Figure 4 In some embodiments, the distance L between the end wall of the second chamber 152 away from the oil passage 17 and the oil passage 17 is 4mm-6mm. Specifically, the distance L between the end wall of the second chamber 152 away from the oil passage 17 and the oil passage 17 can be 4mm, 4.1mm, 4.2mm, 4.3mm, 4.4mm, 4.5mm, 4.6mm, 4.7mm, 4.8mm, 4.9mm, 5mm, 5.1mm, 5.2mm, 5.3mm, 5.4mm, 5.5mm, 5.6mm, 5.7mm, 5.8mm, 5.9mm, or 6mm.
[0051] like Figure 4In some embodiments, the diameter R of the oil passage 17 is 4mm-6mm. Specifically, the diameter R of the oil passage 17 can be 4mm, 4.1mm, 4.2mm, 4.3mm, 4.4mm, 4.5mm, 4.6mm, 4.7mm, 4.8mm, 4.9mm, 5mm, 5.1mm, 5.2mm, 5.3mm, 5.4mm, 5.5mm, 5.6mm, 5.7mm, 5.8mm, 5.9mm, or 6mm.
[0052] By designing the diameter R and height L of the oil passage 17 as described above, the speed at which e-liquid flows through the oil passage 17 into the second chamber 152 is controlled, thus preventing excessive liquid pressure in the second chamber 152 from causing the atomizer core 20 to leak.
[0053] In some embodiments, the oil tank body 10 includes a shell 11, a top cover 12, and a base 13. The top cover 12 is disposed at one end of the shell 11, and the base 13 is disposed at the other end of the shell 11. The partition 16 is disposed inside the shell 11. The space formed between the top cover 12 and the partition 16 serves as a first chamber 151, and the space formed between the base 13 and the partition 16 serves as a second chamber 152. The mouthpiece 14 is disposed on the top cover 12 and has a smoking port 141. The base 13 has an air inlet 131. An atomizing channel 211 is formed inside the atomizing core 20, and the two ends of the atomizing channel 211 are respectively connected to the smoking port 141 and the air inlet 131. The atomizing core 20 is interconnected with the mouthpiece 14 through a smoke guide tube 40, and a smoke guide channel 41 is formed inside the smoke guide tube 40. The smoke guide channel 41 is respectively connected to the atomizing channel 211 and the smoking port 141. Air enters through the air inlet, passing sequentially through the atomizing channel 211, the smoke guiding channel 41, and the smoke inlet 141, forming the internal airway of the electronic cigarette in this embodiment. (See also...) Figure 5 .
[0054] See Figure 6 and Figure 7In some embodiments, the atomizing core 20 includes an atomizing tube 21, within which a heating core 22 is disposed. The heating core 22 includes an oil guide body 221 and a heating element 222. The heating element 222 is disposed on the oil guide body 221. An oil inlet 212 is provided on the atomizing tube 21, corresponding to the oil guide body 221, so that the oil guide body 221 is exposed through the oil inlet 212. In use, the e-liquid in the oil storage chamber 15 is transferred to the oil guide body 221 through the oil inlet 212. The heating element 222 heats up, atomizing the e-liquid on the oil guide body 221. The generated vapor is discharged through the internal airway for the user to inhale. The heating element 222 is electrically connected to the battery core. The heating element 222 is made of conductive metal, or it can be made of graphene or carbon nanotubes. The oil guide body 221 can be made of ceramic, quartz, mica, or glass, or it can be made of cotton or fiber.
[0055] In some embodiments, the base 13 has a sealing member 30 for sealing the second chamber 152 on the side facing the second chamber 152. The sealing member 30 has a groove 31 on the side facing the second chamber 152, and the groove 31 communicates with the second chamber 152. The atomizing core 20 is at least partially inserted into the groove 31, and the oil inlet 212 is located in the groove 31. The groove 31 is designed to collect the e-liquid in the second chamber 152, preventing insufficient e-liquid level from causing dry burning and damaging the atomizer.
[0056] In some embodiments, the oil inlet 212 is located near the bottom wall of the groove 31 to ensure that the e-liquid is fully utilized.
[0057] In other embodiments, the oil inlet 212 may also be located within the second chamber 152, without the groove 31.
[0058] In some embodiments, a lower oil-absorbing cotton 60 is provided between the seal 30 and the base 13 to further absorb e-liquid that has not been atomized in time and to prevent oil leakage.
[0059] In some embodiments, an upper oil-absorbing cotton 50 is provided between the smoke guide tube 40 and the smoking port 141 to absorb the e-liquid condensed at the mouthpiece.
[0060] In some embodiments, the top cover 12 is provided with an oil filling hole 121 and an oil filling plug 122 is provided on the oil filling hole 121. The oil filling plug 122 not only serves as a seal, but also allows the oil filling plug 122 to be opened after the e-liquid in the second chamber 152 is consumed, thereby balancing the air pressure and accelerating the flow of e-liquid in the first chamber 151 into the second chamber 152, thus achieving secondary oil filling.
[0061] Working principle: Since e-liquid is generally quite viscous, its surface tension is relatively high, resulting in a slow flow of e-liquid from the first chamber 151 into the second chamber 152 through the wicking hole 17. When using e-liquid with higher density, the e-liquid in the first chamber 151 may not even flow into the second chamber 152 through the wicking hole 17. This greatly reduces the e-liquid pressure inside the second chamber 152, preventing leakage from the atomizer coil 20. During use, the e-liquid in the first chamber 151 slowly flows into the second chamber 152 through the wicking hole 17. When the e-liquid in the second chamber 152 is almost used up, the filling plug 122 is opened to balance the air pressure inside and outside the reservoir 15, allowing all the e-liquid in the first chamber 151 to flow into the second chamber 152.
[0062] The above are merely embodiments or examples of this disclosure and do not limit the patent scope of this disclosure. Any equivalent structural transformations made based on the concept of this disclosure and the content of this specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this disclosure.
