Description

Technical Field

[0001] This invention relates to the field of tobacco product technology, specifically to an atomizing device and a tobacco product. Background Technology

[0002] Low-temperature cigarettes are a new type of tobacco product that is heated but not burned. The heating source heats the tobacco, and during the heating process, the nicotine and flavoring substances in the tobacco volatilize to produce smoke. Because the tobacco is in a non-combustible state, the smoke does not contain carcinogenic chemicals such as tar and solid particles produced by high-temperature combustion. The harmful chemical components in the smoke are significantly reduced, mitigating the harm to health and making it popular with consumers.

[0003] However, in existing technologies, the heating temperature of cigarette products is low, resulting in a limited maximum amount of smoke produced by the tobacco. The overall amount of smoke produced needs to be improved, and the tobacco smoke is diluted by the air, resulting in a limited concentration and affecting the user experience. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect of limited smoke volume in existing cigarette products, thereby providing an atomizing device and tobacco product that can increase smoke volume.

[0005] To solve the above-mentioned technical problems, the present invention provides an atomizing device, comprising:

[0006] The main body has a sleeve extending from one end;

[0007] The atomizing cylinder is coaxially disposed inside the sleeve, and has an internal cavity to accommodate the vapor cartridge; the outer wall of the atomizing cylinder and the inner wall of the sleeve are kept in contact.

[0008] A porous atomizing tube is disposed on the outer wall of the atomizing cylinder;

[0009] The oil supply device is located inside the main body and is connected to the porous atomizing tube through a pipeline;

[0010] The e-liquid in the oil dispenser is introduced into the porous atomizing tube, heated and atomized, and passes through the porous atomizing tube to form a first smoke stream. The e-liquid cartridge is heated and atomized in the atomizing cylinder to form a second smoke stream.

[0011] Optionally, an annular smoke chamber is provided between the outer peripheral wall of the atomizing cylinder and the inner peripheral wall of the sleeve;

[0012] The first and second smoke streams cannot penetrate the outer peripheral wall of the atomizing cylinder, and the smoke chamber and the cavity are independent of each other.

[0013] Optionally, the end of the smoke chamber away from the main body is closed, and the end of the smoke chamber near the main body is connected to the atomizing cylinder;

[0014] The end of the atomizing cylinder away from the main body is open, allowing the cavity to communicate with the outside. A filter tip is held inside the cavity.

[0015] Optionally, a plurality of the porous atomizing tubes are disposed on the outer peripheral wall of the atomizing cylinder;

[0016] The amount of smoke in the first smoke stream can be increased or decreased by adding or reducing the number of porous atomizing tubes.

[0017] Optionally, it also includes: a heating element, which is respectively coupled to the outer peripheral wall of the atomizing cylinder and the porous atomizing tube;

[0018] The amount of smoke in the second smoke stream can be increased or decreased by adding or reducing the number of heating elements on the atomizing cylinder.

[0019] The amount of smoke from the first smoke stream can be increased or decreased by adding or reducing the number of heating elements on the porous atomizing tube.

[0020] Optionally, the end wall of the atomizing cylinder is a porous end wall, allowing the first smoke stream to pass through the porous end wall and converge with the second smoke stream.

[0021] Optionally, the wall of the porous atomizing tube is made of a porous material;

[0022] Specifically, the amount of smoke emitted from the first smoke stream is changed by adjusting the porosity of the porous atomizing tube.

[0023] Optionally, it also includes: a snap-fit ​​protrusion, which extends outward from the inner wall of one end portion of the atomizing tube and is suitable for snapping the e-cigarette cartridge.

[0024] Optionally, it may also include: a power supply element disposed at one end of the main body and electrically connected to the heating element.

[0025] The present invention provides a tobacco product comprising:

[0026] Atomizing device as described in any of the above;

[0027] The smoke cartridge is embedded in the cavity.

[0028] The technical solution of this invention has the following advantages:

[0029] 1. The atomizing device and tobacco product provided by this invention rationally and efficiently integrate two technologies: e-liquid vaporization and tobacco substance volatilization. This dual-pathway approach yields a composite smoke stream, effectively increasing the amount of smoke inhaled per puff while combining the superior characteristics of both streams and compensating for their respective shortcomings. The smoke stream generated by tobacco substance volatilization results in a high degree of tobacco reduction and an ideal aroma. The smoke stream generated by e-liquid vaporization reduces the irritation of tobacco substances, lowers the impact on the throat, and provides good buffering. E-liquid vaporization produces a high concentration of smoke, increasing the overall smoke concentration and improving the smoking experience. The porous atomizing tube is attached to the outer surface of the atomizing cylinder, saving structural space and improving space utilization.

[0030] 2. The atomizing device and tobacco product provided by the present invention, by setting up mutually independent smoke chambers and cavities, and the atomizing cylinder wall that cannot penetrate the smoke, isolates the first smoke stream and the second smoke stream from each other, so that the generation of the first smoke stream and the second smoke stream do not interfere with each other, ensuring the smooth progress of the atomization process and improving the rationality of the device.

[0031] 3. The atomizing device and tobacco product provided by the present invention can change the amount of smoke produced by the first smoke stream by changing the number or coverage area of ​​the porous atomizing tubes, or by changing the porosity of the porous atomizing tubes, thereby changing the total amount of smoke in a single inhalation, and providing an atomizing device with different smoke volumes at varying heights; by changing the proportion of the first smoke stream in the total smoke stream, the smoke concentration can be changed, thus changing the smoking experience, providing atomizing devices with a variety of different levels of taste, meeting consumer needs, and having a broad market prospect.

[0032] 4. The atomizing device and tobacco products provided by the present invention change the distribution ratio of the heating element on the atomizing cylinder and the porous atomizing tube to change the ratio of the smoke volume of the first smoke stream to the second smoke stream, thereby changing the size and proportion of the smoke volume. This provides consumers with a variety of atomizing devices with different smoke volumes or different proportions of components to choose from, greatly improving the product range, enriching and layering the products, and offering good practicality.

[0042] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0043] Example 1

[0044] Combination Figures 1-3 As shown, the atomizing device provided in this embodiment includes:

[0045] The main body 10 has a sleeve 7 extending from one end;

[0046] The atomizing cylinder 6 is coaxially disposed inside the sleeve 7, and has an internal cavity 61 to accommodate the cigarette cartridge 9; the outer wall of the atomizing cylinder 6 and the inner wall of the sleeve 7 are kept in contact.

[0047] A porous atomizing tube 4 is disposed on the outer wall of the atomizing cylinder 6;

[0048] The oil supply device 2 is located inside the main body 10 and is connected to the porous atomizing tube 4 through the pipeline 3;

[0049] The e-liquid in the oil supply device 2 is introduced into the porous atomizing tube 4, heated, and passes through the porous atomizing tube 4 to form a first smoke stream 11. The e-liquid cartridge 9 is heated in the atomizing cylinder 6 to form a second smoke stream 12.

[0050] It should be noted that the sleeve 7 extends outward along the axial direction of the edge of the main body 10, and the atomizing cylinder 6 is coaxially fixed inside the sleeve 7. The cavity 61 is opened inside the atomizing cylinder 6, and the end of the atomizing cylinder 6 away from the main body 10 is open, and the cavity 61 communicates with the outside. The outer wall of the porous atomizing tube 4 is tightly fixed to the outer wall of the atomizing cylinder 6. The pipeline 3 extends outward from the oil supply device 2 and connects to the end of the porous atomizing tube 4 that is close to or away from the main body 10, so that the inner cavity of the porous atomizing tube 4 is connected to the oil supply device 2. When the pipeline 3 is connected to the end of the porous atomizing tube 4 that is away from the main body 10, the pipeline 3 is tightly attached to the inner wall of the sleeve 7 to prevent obstruction of the smoke flow. The oil supply method of the oil supply device 2 can be oil storage type or oil drip type. The structure of the oil supply device 2 can be a built-in oil storage tank or an external oil supply mechanism.

[0051] In the specific implementation process, the cartridge 9 is introduced into the interior through the open opening of the atomizing cylinder 6, and the outer periphery of the cartridge 9 is in close contact with the inner wall of the atomizing cylinder 6; the e-liquid in the oil supply device 2 is introduced into the inner cavity of the porous atomizing tube 4; the atomizing cylinder 6 and the porous atomizing tube 4 are opened in a controlled manner to heat the cartridge 9 and the e-liquid respectively; the tobacco material in the cartridge 9 is heated and volatilizes to form smoke, and the smoke gathers and flows towards the open end of the atomizing cylinder 6 to form a second smoke stream 12; the porous atomizing tube 4 heats the e-liquid to vaporize it to form smoke, and the smoke gathers and flows towards the open end of the atomizing cylinder 6 to form a first smoke stream 11. The first smoke stream 11 and the second smoke stream 12 converge to form a total smoke stream that flows outward; the smoke stream inhaled by the user in a single inhale is the total smoke stream, which not only greatly increases the amount of smoke contained but also has a high smoke concentration, thus improving the inhalation effect.

[0052] Optionally, the shape of the porous atomizing tube 4 can be, but is not limited to, a cylinder, cone, prism, pyramid, frustum, prism, and sphere; the wall thickness of the porous atomizing tube 4 can be between 0.5mm and 2mm; the material of the porous atomizing tube 4 can be a high-temperature resistant porous material such as porous ceramic, porous calcium carbonate, or porous silicate, so that the vapor obtained from the vaporization of e-liquid can smoothly penetrate the wall of the porous atomizing tube 4 and flow outward; by changing the volume of the inner cavity of the porous atomizing tube 4, the amount of smoke produced in a single inhalation of the first smoke stream can be changed, and the proportion of the first smoke stream 11 in the total smoke stream can be changed, providing a rich and layered smoking experience, with broad market prospects.

[0053] Optionally, the shape of the atomizing cylinder 6 can be cylindrical, with a diameter between 17mm and 30mm and an axial length between 15mm and 65mm. By changing the size of the atomizing cylinder 6, the amount of smoke produced by the second smoke stream 12 can be changed, providing atomizing devices with multiple smoke volume gradients to meet consumer needs.

[0054] Optionally, the outer peripheral wall of the sleeve 7 is coated with a heat-insulating coating to prevent burns to the user; the outer wall of the pipe 3 is coated with a heat-insulating and moisture-absorbing coating to prevent the pipe 3 from being damaged by heat and moisture.

[0055] The atomizing device provided in this embodiment combines e-liquid vaporization and tobacco substance volatilization technologies in a reasonable and efficient manner, resulting in a composite smoke stream through dual pathways. This effectively increases the amount of smoke inhaled per puff while integrating the superior characteristics of both smoke streams and compensating for their respective shortcomings. The smoke stream generated by tobacco substance volatilization gives the total smoke stream a high degree of tobacco reduction and an ideal aroma. The smoke stream generated by e-liquid vaporization reduces the irritation of tobacco substances, lowers the impact on the throat, and provides good buffering. The e-liquid vaporization produces a high concentration of smoke, increasing the concentration of the total smoke stream and improving the inhalation effect. The porous atomizing tube 4 is attached to the outer surface of the atomizing cylinder 6, saving structural space and improving space utilization.

[0056] Specifically, an annular smoke chamber 8 is provided between the outer peripheral wall of the atomizing cylinder 6 and the inner peripheral wall of the sleeve 7;

[0057] The first smoke stream 11 and the second smoke stream 12 cannot penetrate the outer peripheral wall of the atomizing cylinder 6, and the smoke chamber 8 and the cavity 61 are independent of each other.

[0058] In the specific implementation process, the end of the atomizing cylinder 6 away from the main body 10 is suspended and fixed inside the sleeve 7, and the smoke chamber 8 is the annular remaining space inside the sleeve 7; the outer peripheral wall of the atomizing cylinder 6 is made of a material that the smoke stream cannot penetrate; the second smoke stream 12 contains tobacco particles, which will interfere with the formation of the first smoke stream 11; therefore, the second smoke stream 12 is constrained inside the atomizing cylinder 6, and the smoke generated by the e-liquid smoothly passes through the wall of the porous atomizing tube 4 and enters the smoke chamber 8; the generation of the first smoke stream 11 and the second smoke stream 12 do not interfere with each other and are carried out in independent spaces, ensuring the smooth progress of the atomization process and improving the rationality of the device.

[0059] The atomizing device provided in this embodiment isolates the first smoke stream 11 and the second smoke stream 12 by setting up independent smoke chambers 8 and cavities 61, and the atomizing cylinder 6 wall that cannot penetrate the smoke. This ensures that the generation of the first smoke stream 11 and the second smoke stream 12 does not interfere with each other, thus guaranteeing the smooth progress of the atomization process and improving the rationality of the device.

[0060] Specifically, the end of the smoke chamber 8 away from the main body 10 is closed, and the end of the smoke chamber 8 near the main body 10 is connected to the atomizing cylinder 6;

[0061] The atomizing device also includes a filter section 91, which is connected to the other end of the atomizing cylinder 6. The other end of the atomizing cylinder 6 is the end that is away from the smoke chamber 8 and connected to the atomizing cylinder 6.

[0062] In the specific implementation process, the edge of the open end of the atomizing cylinder 6 extends radially until it connects with the sleeve 7, thereby closing the smoke chamber 8; the smoke chamber 8 is connected to the atomizing cylinder 6, and a gap is left between the end face of the atomizing cylinder 6 near the main body 10 and the main body 10; the first smoke flow 11 flows axially in the smoke chamber 8 to the space between the atomizing cylinder 6 and the main body 10, and then enters the atomizing cylinder 6 to converge with the second smoke flow 12 to form a total smoke flow; the filter section 91 is engaged with the open port of the atomizing cylinder 6, and the total smoke flow flows outward through the filter section 91.

[0063] Specifically, multiple porous atomizing tubes 4 are evenly distributed around the outer peripheral wall of the atomizing cylinder 6;

[0064] The number of porous atomizing tubes 4 is proportional to the amount of smoke from the first smoke stream 11.

[0065] It should be noted that the porous atomizing tubes 4 can be distributed independently on the outer peripheral surface of the atomizing cylinder 6, or adjacent porous atomizing tubes 4 can be bonded together to form a porous atomizing covering layer on the outer peripheral surface of the atomizing cylinder 6. The coverage area of ​​the porous atomizing covering layer can be between 10% and 100% of the area of ​​the outer peripheral surface of the atomizing cylinder 6.

[0066] In the specific implementation process, multiple porous atomizing tubes 4 are evenly spaced around the axis of the atomizing cylinder 6 and fixed to the outer peripheral surface of the atomizing cylinder 6. Multiple pipes 3 extend outward from the oil supply unit 2 and are respectively connected to the porous atomizing tubes 4 one-to-one. By changing the number or coverage area of ​​the porous atomizing tubes 4, the amount of smoke produced by the first smoke stream 11 is changed, and the total amount of smoke inhaled in a single session is changed, providing an atomizing device with different smoke volumes at varying heights. By changing the proportion of the first smoke stream 11 in the total smoke stream, the smoke concentration is changed, and the inhalation taste is changed, providing atomizing devices with multiple levels of taste to meet consumer needs and have broad market prospects.

[0067] Specifically, it also includes: heating element 5, which is respectively connected to the outer peripheral wall of the atomizing cylinder 6 and the porous atomizing tube 4;

[0068] The number of heating elements 5 on the atomizing cylinder 6 is proportional to the amount of smoke from the second smoke stream 12;

[0069] The number of heating elements 5 on the porous atomizing tube 4 is proportional to the amount of smoke from the first smoke stream 11.

[0070] In the specific implementation process, the heating element 5 is disposed on the outer peripheral wall of the atomizing cylinder 6 and the porous atomizing tube 4; different composite connection methods are selected according to the different types of heating element 5. The heating element 5 can be a heating wire, and the composite method is that the heating wire is embedded in the wall; the heating element 5 can be a thin film, and the composite method is thin film printed circuit; the heating element 5 can also be a low temperature ceramic, and the composite method is cast film co-fired.

[0071] By changing the distribution ratio of the heating element 5 on the atomizing cylinder 6 and the porous atomizing tube 4, the smoke volume ratio of the first smoke stream 11 to the second smoke stream 12 is changed, with the smoke volume ratio ranging from 30:70 to 70:30; thereby changing the amount and proportion of smoke, providing consumers with a variety of atomizing devices with different smoke volumes or different proportions of smoke, greatly improving product variety, enriching and layering products, and offering good practicality.

[0072] Optionally, the heating element 5 is made of a thermally conductive material, which can be one or more of the following materials in combination: metal, polymer, inorganic oxide, or carbon.

[0073] Specifically, the end wall of the atomizing cylinder 6 is a porous end wall 62, so that the first smoke stream 11 passes through the porous end wall 62 and converges with the second smoke stream 12.

[0074] In the specific implementation process, the end wall of the atomizing cylinder 6 near the main body 10 is the porous end wall 62. The porous end wall 62 is made of porous material, and the pore size is only enough to allow smoke to pass through, preventing the leakage of tobacco raw materials. The first smoke stream 11 can pass through the porous end wall 62 and enter the interior of the atomizing cylinder 6, and merge with the second smoke stream 12 to form the total smoke stream.

[0075] Specifically, the wall of the porous atomizing tube 4 is made of a porous material;

[0076] Specifically, the amount of smoke emitted from the first smoke stream 11 is changed by adjusting the porosity of the porous atomizing tube 4.

[0077] In the specific implementation process, the wall of the porous atomizing tube 4 is made of porous material, which ensures that the e-liquid does not leak while allowing the smoke to pass through the porous wall and enter the smoke chamber 8; the porosity of the porous atomizing tube 4 can be changed by changing the porosity, and the porosity adjustment range can be from 20% to 80%; the porosity of the porous atomizing tube 4 is directly proportional to the amount of smoke in the first smoke stream 11, and the amount of smoke can be changed by changing the porosity of the porous atomizing tube 4, which is highly practical.

[0078] Specifically, it also includes: a snap-fit ​​protrusion 63, which extends outward from the inner wall of one end of the atomizing tube 6 and is suitable for snapping the e-cigarette cartridge.

[0079] In the specific implementation process, at least two of the snap-fit ​​protrusions 63 are evenly spaced around the axis of the atomizing cylinder 6 on the inner wall of the atomizing cylinder 6; after the cartridge 9 is inserted into the cavity 61, the snap-fit ​​protrusions 63 abut against the outer peripheral surface of the cartridge 9, restricting the outward sliding of the cartridge 9, which is highly practical.

[0080] Specifically, it also includes: a power supply element 1, which is located at one end of the main body 10 and electrically connected to the heating element 5.

[0081] In the specific implementation process, the power supply element 1 is connected to the end of the main body 10 away from the sleeve 7; the power supply element 1 can control the working state of the heating element 5; the power supply element 1 can be an external power supply device or a built-in energy storage device, and the energy storage device can be a primary battery or a rechargeable battery.

[0082] The tobacco product provided in this embodiment includes:

[0083] Atomizing device as described in any of the above;

[0084] The smoke cartridge 9 is built into the cavity 61.

[0085] In the specific implementation process, the tobacco segment of the cartridge 9 is introduced into the atomizing cylinder 6, and the e-liquid in the oil supply device 2 is introduced into the porous atomizing tube 4; the heating element 5 located on the porous atomizing tube 4 and the atomizing cylinder 6 is controlled to heat the cartridge 9 and the e-liquid simultaneously, generating the first smoke stream 11 and the second smoke stream 12 respectively. The first smoke stream 11 and the second smoke stream 12 converge in the atomizing cylinder 6 to form a total smoke stream, which is filtered through the filter section 91 and then inhaled by the user.

[0086] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
