Description

Technical Field

[0001] The present invention relates to the technical field of nicotine oral products, in particular to a buccal cigarette. Background Art

[0002] Currently, snus is gradually becoming an alternative to traditional cigarettes due to its features such as no secondhand smoke and ease of use. Snus mainly relies on passive penetration or pre-packaged sustained-release technology to promote direct nicotine absorption by the oral mucosa, avoiding harmful substances produced by combustion, but it still has many problems. Specifically, nicotine bags currently on the market mostly use porous carriers to adsorb nicotine, and then rely on saliva to dissolve or penetrate to release nicotine. However, since the pore structure of the carrier material is difficult to precisely control, users cannot adjust the release speed and dosage according to their needs. The nicotine release rate is uneven, the initial release is too fast, which can easily cause oral irritation, and the later release is insufficient, affecting the user experience.

[0003] Current research has attempted to optimize nicotine release and product experience. For example, controlling release by adjusting the pore size (1μm-40μm) of microporous ceramic / silica gel carriers, but achieving a precise sustained-release effect is difficult.

[0010] In some embodiments, a side of the first end facing away from the second end is a hemispherical structure.

[0011] In some embodiments, a first sealing layer is provided on the inner side wall of the sliding groove; and / or a second sealing layer is provided on the outer side wall of the pressing member.

[0017] Beneficial effects of the present invention:

[0018] The present invention provides a buccal cigarette, which is provided with a accommodating chamber inside a shell, and a barrier member is provided in the accommodating chamber to divide the accommodating chamber into a first sub-chamber and a second sub-chamber, and an outflow hole is provided on the lower surface of the shell so that the tobacco liquid contained in the second sub-chamber can flow out from the outflow hole when subjected to pressure; in addition, a sliding groove is provided, and a first one-way valve capable of one-way communication between the sliding groove and the external environment is provided at the bottom of the sliding groove; and a pressing member at least partially located inside the sliding groove is provided, and a second one-way valve capable of communicating between the inside of the sliding groove and the external environment is provided on the pressing member. In this way, when the pressing member moves toward the bottom of the sliding groove, the pressing member compresses the space inside the sliding groove, increasing the gas pressure inside the sliding groove. At this time, the gas inside the sliding groove can flow into the first sub-chamber through the first one-way valve, increasing the gas pressure in the first sub-chamber, thereby pushing the blocking member to move toward the second sub-chamber. The blocking member compresses the space inside the second sub-chamber, increasing the pressure in the second sub-chamber, and then forcing the tobacco liquid in the second sub-chamber to flow out from the outflow hole for user use. As the tobacco liquid in the second sub-chamber flows out, the pressure in the second sub-chamber is balanced with the pressure of the external environment, so that the tobacco liquid in the second sub-chamber stops flowing out.

It is simple and convenient, and improves the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] like Figures 1 to 4As shown, this embodiment provides a buccal cigarette, which includes a shell 1, a sliding groove 4 and a pressing member 5.

[0031] The material of the housing 1 can be food grade hard plastic, such as polypropylene, high density polyethylene, polyethylene terephthalate, polycarbonate, etc. Figure 1 As shown, a housing 1 is provided with a housing chamber 11. A barrier 2 is provided inside the housing chamber 11, such as a piston or a rubber baffle. The outer wall of the barrier 2 is fitted with the inner wall of the housing chamber 11 to separate the housing chamber 11 into a first sub-chamber 111 and a second sub-chamber 112. The second sub-chamber 112 contains smoke oil 3, and an outflow hole 12 is provided on the lower surface of the housing 1. The second sub-chamber 112 is connected to the external environment through the outflow hole 12, so that the smoke oil 3 inside the second sub-chamber 112 can flow out from the outflow hole 12 when subjected to pressure.

[0032] Specifically, the volume of the second sub-chamber 112 is, for example, 1 ml to 2 ml. The tobacco oil 3 disposed inside the second sub-chamber 112 is a liquid containing active ingredients such as nicotine, and has low fluidity at room temperature. Its ingredients include: solvent (propylene glycol / glycerin mixture to ensure low viscosity); nicotine salt and / or tobacco extract; flavoring; fragrance; preservative; pH adjuster, etc. The shape of the above-mentioned accommodating chamber 11 can be circular or elliptical, so that the inner side wall of the accommodating chamber 11 can form a smooth transition, that is, the inner side wall of the second sub-chamber 112 can form a smooth transition, which facilitates the outflow of the tobacco oil 3 inside the second sub-chamber 112.

[0033] It is easy to understand that whether the smoke liquid 3 can flow out of the outlet 12 when there is no pressure is related to the balance between the surface tension pressure difference and the hydrostatic pressure. (where γ is the surface tension of the liquid, θ is the contact angle, and r is the radius of the pore) and the hydrostatic pressure formula ΔP 静水 =ρgh, (where ρ is the liquid density, g = 9.81m / s 2 , h is the liquid level height) is calculated, that is, ΔP should be 表面 ≥ΔP 静水 .

[0034] Specifically, taking water as an example, the surface tension of water at 20°C is γ = 0.072 N / m, and the density of water is ρ = 1000 kg / m 3Since the outflow hole 12 is located on the lower surface of the housing 1, and the housing 1 is made of food-grade hard plastic, which is hydrophobic, and the contact angle θ is 120°, and the volume of the second sub-chamber 112 is 2 ml, and the liquid level height h is 10 mm, a simple calculation shows that the diameter r of the outflow hole 12 is approximately 1.47 mm or less. That is, after 2 ml of water is placed in the second sub-chamber 112, setting the diameter of the outflow hole 12 on the lower surface of the housing to less than 1.47 mm will ensure that the water in the second sub-chamber 112 does not flow out of the outflow hole 12 under the action of gravity. Furthermore, the e-liquid 3 in this embodiment is not pure water; it has low fluidity and low viscosity. Once the e-liquid 3 is placed in the second sub-chamber 112, due to its low fluidity and low viscosity, it is less likely to flow out of the outflow hole 12 under the action of gravity than pure water. Those skilled in the art may even increase the diameter of the outflow hole 12. This shows that the structural design of the buccal cigarette in this embodiment is feasible.

[0035] like Figure 1 As shown, the sliding groove 4 is set through the lower surface of the housing 1 and extends along the first direction X1, where the first direction X1 is the vertical direction. The sliding groove 4 is, for example, a cylindrical groove structure. Figure 1 Taking the perspective shown as an example, the sliding groove 4 passes through the lower surface of the shell 1 in the vertical direction, but does not pass through the upper surface of the shell 1. The inner wall of the sliding groove 4 is provided with a first one-way valve 41, and the sliding groove 4 is connected to the first sub-chamber 111 of the accommodating chamber 11 in one direction through the first one-way valve 41. Specifically, the first one-way valve 41 is, for example, a ball valve one-way valve, or a diaphragm one-way valve. By setting the first one-way valve 41, the gas in the sliding groove 4 can only flow in one direction to the first sub-chamber 111, and the gas in the first sub-chamber 111 cannot flow back to the sliding groove 4. The above-mentioned first one-way valve 41 is provided at the bottom of the sliding groove 4, that is, with Figure 1 Taking the perspective shown as an example, the first one-way valve 41 is arranged at the upper end of the sliding groove 4.

[0036] Combine Figure 1 、 Figure 2 shown or combined Figure 3 、 Figure 4 As shown, it is easy to understand that the aforementioned accommodating chamber 11 can be an annular accommodating chamber 11, and the sliding groove 4 can be provided at the center of the annular accommodating chamber 11. In this case, the outer peripheral wall of the sliding groove 4 is surrounded by the accommodating chamber 11. To improve the flow efficiency of the airflow, multiple first one-way valves 41 can be provided on the sliding groove 4. The sliding groove 4 communicates with the first sub-chamber 111 of the accommodating chamber 11 through the multiple first one-way valves 41. Similarly, to improve the outflow efficiency of the smoke liquid 3 in the second sub-chamber 112, the aforementioned outflow port can also be provided in multiple locations.

[0037] The pressing portion is at least partially located within the sliding groove 4. The pressing member 5 is movable in a first direction X1. A second one-way valve 51 is provided on the pressing member 5, and the sliding groove 4 is in one-way communication with the outside environment through the second one-way valve 51. Specifically, air from the outside environment can only flow into the sliding groove 4 in one direction, while air within the sliding groove 4 cannot flow back to the outside environment.

[0038] The movement of the pressing member 5 along the first direction X1 can increase or decrease the air pressure inside the sliding groove 4. Specifically, when the pressing member 5 moves toward the bottom of the sliding groove 4, the pressing member 5 compresses the space inside the sliding groove 4, thereby increasing the air pressure inside the sliding groove 4; when the pressing member 5 moves away from the bottom of the sliding groove 4, the space inside the sliding groove 4 expands, thereby decreasing the air pressure inside the sliding groove 4. Figure 1 Taking the perspective shown as an example, when the pressing member 5 moves upward, the pressure inside the sliding groove 4 increases, and when the pressing member 5 moves downward, the pressure inside the sliding groove 4 decreases.

[0039] Thus, the present embodiment provides a buccal cigarette, which has a housing 1, a housing 1, and a barrier 2 provided in the housing 11 to divide the housing 11 into a first sub-chamber 111 and a second sub-chamber 112, and an outflow hole 12 provided on the lower surface of the housing 1, so that the tobacco liquid 3 provided in the second sub-chamber 112 can flow out from the outflow hole 12 when subjected to pressure; in addition, a sliding groove 4 is provided, and a first one-way valve 41 capable of one-way communication between the sliding groove 4 and the external environment is provided at the bottom of the sliding groove 4, and a pressing member 5 is provided, which is at least partially located in the sliding groove 4, and a second one-way valve 51 capable of communicating between the interior of the sliding groove 4 and the external environment is provided on the pressing member 5. In this way, when the pressing member 5 moves toward the bottom of the sliding groove 4, the pressing member 5 compresses the space inside the sliding groove 4, increasing the gas pressure inside the sliding groove 4. At this time, the gas inside the sliding groove 4 can flow from the first one-way valve 41 to the first sub-chamber 111, increasing the gas pressure in the first sub-chamber 111, thereby pushing the blocking member 2 to move toward the second sub-chamber 112. The blocking member 2 compresses the space inside the second sub-chamber 112, increasing the pressure in the second sub-chamber 112, and then forcing the smoke oil 3 in the second sub-chamber 112 to flow out from the outflow hole 12 so that the user can use it. As the e-liquid 3 in the second sub-chamber 112 flows out, the pressure in the second sub-chamber 112 balances with the ambient pressure, stopping the e-liquid 3 from flowing out. As the pressing member 5 moves away from the bottom of the sliding groove 4, the space inside the sliding groove 4 expands, reducing the gas pressure therein (forming a negative pressure). Due to the first one-way valve 41, the gas in the first sub-chamber 111 cannot flow back into the sliding groove 4. Gas from the ambient environment can flow through the second one-way valve 51 into the sliding groove 4, refilling the sliding groove 4 for the next use. Through simple physical manipulation, namely, controlling the movement of the pressing member 5 in the first direction X1, on-demand release of e-liquid 3 can be achieved (the longer the pressing member 5 moves toward the bottom of the sliding groove 4, the more e-liquid 3 flows out; the shorter the pressing member 5 moves toward the bottom of the sliding groove 4, the less e-liquid 3 flows out). This is simple and convenient, improving the user experience.

[0040] In some embodiments, as Figure 1 As shown, the pressing member 5 is a columnar structure, such as a cylindrical structure. The pressing member 5 extends along the first direction X1 and can slide in the sliding groove 4 along the first direction X1. The outer wall of the pressing member 5 is arranged to fit the inner wall of the sliding groove 4. In other words, there is always a contact constraint between the outer wall of the pressing member 5 and the inner wall of the sliding groove 4. An air flow channel 52 is provided on the pressing member 5. The air flow channel 52 passes through the pressing member 5 along the first direction X1, that is, Figure 2Taking the perspective shown as an example, one end (upper end) of the airflow channel 52 is connected to the interior of the sliding groove 4, and the other end (lower end) of the airflow channel 52 is connected to the external environment. The second one-way valve 51 is disposed inside the airflow channel 52.

[0041] like Figure 1 As shown, the snus further includes a restoring member 6. The restoring member 6 is disposed between the bottom of the sliding groove 4 and the pressing member 5. The restoring member 6 is capable of constantly pushing against the pressing member 5 in the first direction X1, that is, providing a stable elastic restoring force when the pressing member 5 moves in the first direction X1. Specifically, one end of the restoring member 6 is in close contact with or fixedly connected to the bottom of the sliding groove 4, while the other end maintains contact with or is connected to the bottom end of the pressing member 5, thereby ensuring that the pressing member 5 is constantly elastically resisted by the restoring member 6.

[0042] From a structural design perspective, the reset element 6 can be implemented in a variety of ways. For example, a coil spring can be used as the reset element 6, which provides a stable and linear elastic force; or a rubber elastic column can be used, which provides a gentle elastic restoring force. In addition, an elastic diaphragm or other types of elastic elements can be considered to meet different design needs and performance requirements.

[0043] The core function of the reset member 6 is that when the pressing member 5 is pressed downward, the reset member 6 is compressed to store elastic potential energy; and when the external force is removed, the reset member 6 quickly releases the elastic potential energy, pushing the pressing member 5 smoothly back to its initial position. This design not only ensures that the pressing member 5 can achieve a reliable reset operation, but also maintains the dynamic balance of the air pressure inside the sliding groove 4, thereby ensuring the working stability of the entire device. By adopting this design with a reset member 6, the oral cigarette device can achieve easy operation and precise reset of the pressing member 5, providing users with a more convenient and comfortable user experience.

[0044] The above arrangement allows the pressing member 5 to move along the extension direction of the sliding groove 4 when it is pushed in the direction close to the bottom of the sliding groove 4, thereby compressing the volume inside the sliding groove 4, increasing the gas pressure inside the sliding groove 4, and compressing the elastic member at the same time. When the pushing of the pressing member 5 stops, the elastic member resets and pushes the pressing member 5 in the direction away from the bottom of the sliding groove 4, causing the pressing member 5 to move in the direction away from the bottom of the sliding groove 4. In this way, the volume inside the sliding groove 4 can be restored and the gas pressure inside the sliding groove 4 can be reduced. The above arrangement allows the pressing member 5 to increase or decrease the gas pressure inside the sliding groove 4 when it moves in the first direction X1, resulting in a simple structure and convenient use.

[0045] In some embodiments, as Figure 1As shown, the pressing member 5 has one end facing away from the bottom of the sliding groove 4 as a first end 53, and the other end as a second end 54. The first end 53 of the pressing member 5 is at least partially located outside the sliding groove 4. The end surface of the second end 54, the bottom of the sliding groove 4, and the inner sidewall of the sliding groove 4 form a first sealed cavity 42. The first one-way valve 41 is disposed on the inner sidewall of the first sealed cavity 42. Movement of the pressing member 5 in the first direction X1 can increase or decrease the air pressure within the first sealed cavity 42. This arrangement facilitates installation of the pressing member 5.

[0046] In some embodiments, as Figure 1 As shown in FIG. 1 , the first end 53 of the pressing member 5 is in a hemispherical structure on the side away from the bottom of the sliding groove 4. Figure 4 Taking the perspective shown as an example, the lower end of the pressing member 5 is hemispherical. This configuration allows the surface of the first end 53 of the pressing member 5 to be smoothly rounded, avoiding the formation of angular structures, making it easier to apply force to the pressing member 5 and improving the user experience when using the snus.

[0047] In some embodiments, a first sealing layer is provided on the inner sidewall of the sliding groove 4; and / or a second sealing layer is provided on the outer sidewall of the pressing member 5. The first and second sealing layers are made of flexible materials, such as rubber. This arrangement improves the fit between the inner sidewall of the sliding groove 4 and the outer sidewall of the pressing member 5, thereby enhancing the seal between them. This prevents gas within the sliding groove 4 from leaking into the external environment and affecting the outflow of the e-liquid 3, thereby ensuring the reliability of the snus during use.

[0048] In some embodiments, as Figure 3 As shown, the pressing member 5 is in a sheet-like structure. The pressing member 5 includes a connecting portion 55 and an elastic pressing portion 56. The connecting portion 55 is connected to the inner side wall of the sliding groove 4, and the connection method between the two here is, for example, bonding. The second one-way valve 51 is arranged on the connecting portion 55. The elastic pressing portion 56 can move in the first direction X1 (that is, deform along the first direction X1), and the elastic pressing portion 56 is, for example, a silicone sheet, a fluorosilicone rubber sheet, etc. In the first direction X1, the distance between the elastic pressing portion 56 and the bottom of the sliding groove 4 is greater than the distance between the connecting portion 55 and the bottom of the sliding groove 4, so that sufficient movement distance (deformation distance) can be reserved for the elastic pressing portion 56.

[0049] At this time, the side of the pressing member 5 (i.e., the sheet-like pressing member 5) near the bottom of the sliding groove 4, the bottom of the sliding groove 4, and the inner sidewall of the sliding groove 4 form a second sealed cavity 43. The first one-way valve 41 is disposed on the inner sidewall of the second sealed cavity 43. Movement of the elastic pressing portion 56 along the first direction X1 can increase or decrease the air pressure within the second sealed cavity 43. This arrangement allows the pressing member 5 to increase or decrease the air pressure within the sliding groove 4 by moving along the first direction X1, resulting in a simple structure, easy installation, and low manufacturing cost.

[0050] In some embodiments, as Figure 3 As shown, the elastic pressing portion 56 has a hemispherical structure and at least partially protrudes from the lower surface of the housing 1. This arrangement allows for sufficient movement distance (deformation distance) for the elastic pressing portion 56, while also providing a smooth transition on the surface of the pressing portion, avoiding the formation of angular structures. This facilitates the application of force to the pressing member 5 and enhances the user experience when using the snus.

[0051] In some embodiments, as Figure 1 、 Figure 3 As shown, the shape of the cross section of the shell 1 is an ellipse. The direction of the cross section is perpendicular to the second direction X2 and parallel to the first direction X1. Here, the first direction X1 and the second direction X2 are set at an angle, and the angle is, for example, 90°. Specifically, the short axis of the ellipse is set parallel to the first direction X1, and the long axis of the ellipse is set parallel to the second direction X2. By adopting the design of an elliptical cross section, the outer surface of the shell 1 presents a smooth transition shape. This design avoids the discomfort that may be caused by the angular structure. In addition, after the ratio of the major axis and the minor axis of the ellipse is appropriately designed, it can not only ensure the structural strength of the product, but also take into account the ergonomic requirements. This smooth appearance design not only improves the aesthetics of the product, but more importantly, it can better fit the oral structure in actual use, thereby significantly improving the wearing comfort of the user.

[0052] In some embodiments, as Figure 1 and Figure 3As shown, a flexible layer 8 is provided on the upper surface of the shell 1. The flexible layer 8 is made of an elastomeric material, and specifically, materials with excellent elasticity and resilience properties such as thermoplastic elastomer, silicone, and rubber can be selected. After the thickness of the flexible layer 8 is appropriately designed, it can provide sufficient cushioning performance without affecting the overall structural strength of the shell 1. By providing a flexible layer 8 on the upper surface of the shell 1, the pressure generated during use can be effectively buffered, and direct hard contact between the upper surface of the shell 1 and the user's mouth can be avoided. This design can significantly improve the user's comfort, especially when used for a long time, it can effectively reduce the fatigue and discomfort in the user's oral area. In addition, the surface of the flexible layer 8 has good touch and anti-slip properties, which further enhances the user experience of the product.

[0053] In some embodiments, the shell 1 is further provided with an observation window, which is opposite to the second sub-chamber 112. The capacity of the e-liquid 3 inside the second sub-chamber 112 can be visually observed through the observation window. It is easy to understand that the observation window should be made of a transparent material, such as a polyester material, which has good light transmittance and durability. The shape of the observation window can be specifically set according to the overall design of the shell 1, such as an oval or rectangular shape, and its size is optimized to provide a sufficient field of view without affecting the structural strength of the shell 1. The installation position of the observation window is usually located on the side of the shell 1, so that the user can check the remaining amount of the e-liquid 3 at any time during use. Through the above design, the observation window can not only help the user to grasp the capacity of the e-liquid 3 in real time, avoid affecting the user experience due to insufficient e-liquid, but also enhance the overall aesthetics and practicality of the product.

[0054] In some embodiments, as Figure 1 、 Figure 3 As shown, the lower surface of the housing 1 is provided with a cover 7, which is compatible with the lower surface of the housing 1 and can be removably connected to the lower surface of the housing 1. The removable connection between the two can be achieved by, for example, snap-fitting or threading. Specifically, the lower surface of the housing 1 is provided with a groove structure, and the edge of the cover 7 is designed with a protrusion structure that matches the groove structure on the lower surface of the housing 1. The groove structure and the protrusion structure can be directly snap-fitted, or the groove structure can be provided with internal threads and the protrusion structure with external threads, so that the groove structure and the protrusion structure can be connected by threading. A sealing ring can also be provided on the inside of the cover 7 to further enhance the sealing performance and prevent the leakage or volatilization of the tobacco liquid. The cover 7 can cover the pressing member 5, forming an effective protective barrier. When the snus is not in use, the cover 7 prevents external dust and stains from adhering to the surface of the pressing member 5. It also prevents misoperation caused by accidentally touching the pressing member 5, effectively improving the safety of the product and the user experience.
