Description

Technical Field

[0001] The present invention belongs to the technical field of heating devices, and in particular relates to a flexible sealed heating smoking device and a use method thereof. Background Art

[0002] Existing heat-not-burn cigarettes heat the cigarette directly or indirectly, and use the airflow passing through the cigarette as a carrier to inhale the aerosol produced by the heated cigarette into the smoker's mouth to form smoke. In order to ensure that the tobacco segment does not burn, the heating temperature of the cigarette generally does not exceed 300°C. Compared with traditional cigarettes, although heat-not-burn cigarettes do not have harmful components such as tar produced during combustion, it is difficult to fully release the aroma components of tobacco, so this type of cigarette is less accepted by traditional smokers.

[0003] If the smoking device adopts a closed cigarette heating structure with no air intake at the end (i.e., there is no gap for air intake between the cigarette and the cigarette holding cavity), when a normal ventilated cigarette (normal ventilation at both ends of the cigarette) is inserted into it, the oxygen content of the tobacco segment will decrease during the heating process. This is due to the replacement effect of the newly formed fresh smoke on the internal gas of the cigarette. When the heating temperature gradually increases, the cigarette will not burn. At the same time, the tobacco in the cigarette and the air inside it are quickly heated from the ambient temperature to the working temperature of the smoking device. At this time, the internal gas pressure increases, and the tobacco aroma components of the tobacco are also discharged from the smoking device together with the high-pressure gas to form a smoke aerosol.

[0004] However, as the central heating element continues to heat the cigarette, the heat increases rapidly during the continuous heating stage from room temperature to the beginning of smoking. When the central heating element reaches the operating temperature, the temperature no longer increases, and the increment of smoke aerosol overflow in the cigarette holding cavity is not as high as that in the heating stage. Since there is no continuous airflow through the tobacco section, the natural overflow of smoke aerosol will be significantly insufficient only by the pressure difference or the effect of the filter part of the cigarette, resulting in insufficient smoke after about 1 / 5 of a cigarette is smoked.

[0005] In order to solve the above-mentioned problems, the present invention is proposed. Summary of the invention

[0006] A first aspect of the present invention provides a flexible sealed heating smoking device, the heating smoking device comprising a sealing heating component and a vibrating smoke outlet component;

[0007] A flexible sealing sleeve 3, the interior of which is a sealing cavity, a rigid sealing ring 5 having a rigid ridge 51 on the outer surface is arranged inside the upper end of the sealing sleeve 3, and the rigid ridge 51 on the sealing ring 5 is arranged toward the side wall of the sealing sleeve 3, so that the inner wall of the sealing cavity has a raised clamping ridge 34;

[0008] A central heating element 1, which is arranged inside the sealed cavity;

[0009] The vibration smoke outlet assembly comprises:

[0010] A vibration block 4 disposed on the periphery of the sealed cavity;

[0011] The power supply device provides power to the vibration block 4 to press the side wall of the flexible sealing sleeve 3 inwardly.

[0012] Preferably, the upper end of the sealing sleeve 3 is a semi-closed "C"-shaped sealing cavity port 33, and the opening of the "C"-shaped sealing cavity port 33 is away from the sealing cavity or downward, and a rigid sealing ring 5 with a rigid ridge 51 on the outer wall surface is arranged inside the cavity of the "C"-shaped sealing cavity port 33. The rigid ridge 51 on the sealing ring 5 is arranged toward the side wall of the sealing sleeve 3, so that the inner wall of the sealing cavity has a raised clamping ridge 34.

[0013] Preferably, the rigid ridge 51 and the clamping ridge 34 are both annular.

[0014] Preferably, the clamping ridge 34 protrudes from the inner wall of the sealing cavity by 0.03 to 0.25 mm.

[0015] The inner diameter of the clamping ridge 34 is smaller than the outer diameter of the cigarette.

[0016] The central heating element 1 is a heating needle or a heating sheet, and has good sealing performance with the sealing sleeve 3 .

[0017] Preferably, the outer diameter of the sealing cavity port 33 is larger than the outer diameter of the sealing sleeve 3 body, so as to provide better support and clamping for the inserted cigarette.

[0018] The sealing sleeve 3 is molded from high temperature resistant non-toxic and odorless silicone rubber or other materials.

[0019] The materials used in the flexible sealing sleeve 3 herein are both flexible and elastic, that is, these materials deform after being subjected to force, and can restore their original shapes after the force is lost.

[0020] The rigid sealing ring 5 is preferably a circular ring made of aluminum alloy or steel. During installation, the elasticity and flexibility of the sealing sleeve 3 can be used to embed the sealing ring 5 into the "C"-shaped cavity of the sealing cavity port 33. After the sealing ring 5 is embedded, the rigid ridge 51 on the sealing ring 5 squeezes the flexible sealing sleeve 3, so that the inner wall of the sealing cavity has a raised clamping ridge 34.

[0021] Preferably, the surface of the vibration block 4 facing the sealing cavity has linear or dot-shaped protrusions 41. This reduces the area of ​​direct contact between the vibration block 4 and the sealing sleeve 3, and improves the effect of "hitting" or "squeezing" the cigarette.

[0022] Preferably, the main body of the flexible sealing sleeve 3 is a hollow cylinder, the vibration block 4 is a ferromagnetic block, and the shape of the vibration block 4 is an arc-shaped, and the circle where the arc is located and the sealing cavity are concentric circles, and the vibration block 4 surrounds a semicircular part on one side of the sealing cavity and can be movably fixed by a vibration block limiting device;

[0023] The power supply device comprises: a U-shaped iron core 7, a coil 8, and an iron core fixing device;

[0024] The coil 8 is wound around the U-shaped iron core 7 to form an electromagnet together with the U-shaped iron core 7. The iron core fixing device enables the U-shaped iron core 7 to surround the other semicircular part of the sealed cavity, and the distance between the two ends of the U-shaped iron core 7 and the two ends of the vibration block 4 is L;

[0025] The positions of the U-shaped core 7 and the vibration block 4 are designed as follows:

[0026] When the coil 8 is energized, the two ends of the U-shaped iron core 7 attract the two ends of the vibration block 4 , L becomes smaller, and the flexible sealing sleeve 3 is squeezed.

[0027] When the coil 8 is not energized, the flexible sealing sleeve 3 rebounds, causing the vibration block 4 to reset. Therefore, when the coil 8 is turned on at a certain frequency, the vibration block 4 can reciprocate and squeeze the flexible sealing sleeve 3 to discharge the smoke therein.

[0028] Preferably, the coil 8 includes a first coil and a second coil, and the two coils are respectively wound around two ends of the U-shaped iron core, and the winding method is such that when the two coils are energized, the two ends of the U-shaped iron core are S and N poles respectively.

[0029] Preferably, the vibration block limiting device is designed as follows: at least three positioning pins 31 are fixed on the outside of the flexible sealing sleeve 3, the vibration block 4 is limited on the periphery of the flexible sealing sleeve 3 by several positioning pins 31, and the positioning pins 31 and the vibration block 4 are loosely matched, and a small amount of graphite powder is coated between them, which is lubricating, high temperature resistant, non-toxic, and tasteless, and is convenient for the radial vibration of the vibration block in the sealing sleeve 3, and each positioning pin 31 has a stop cap 32 at the end. The stop cap 32 can facilitate connection during installation and prevent the vibration block 4 from slipping during normal use.

[0030] Preferably, the core fixing device is designed as follows:

[0031] A sealed cavity pad 22 is arranged on the periphery of the other semicircular part of the sealed cavity, and the middle of the upper part of the sealed cavity pad 22 has an iron core groove 21 for fixing the iron core 7. The sealed cavity pad 22 has a hole 23 and a clamping device on both sides of the left and right symmetric sides. The two ends of the iron core 7 are inserted into the two holes 23 and clamped and fixed by the clamping device at a position where the distance between the two ends of the iron core 7 and the two ends of the vibration block 4 is L. The function of the sealed cavity pad 22 is heat insulation and side wall support.

[0032] Preferably, a supporting base 2 is provided at the lower portion of the sealed cavity, and the sealed cavity gasket 22 is fixedly connected to the base 2 .

[0033] Preferably, L is 0.05-1.00 mm.

[0034] The second aspect of the present invention provides a method for using the heating tobacco device described in the first aspect, wherein a cigarette is inserted into the sealed cavity, the clamping ridge 34 squeezes and tightens the cigarette, the central heating element 1 is started, and then the power supply device is started, the vibration block 4 begins to reciprocately squeeze the side wall of the sealing sleeve 3, and the smoke in the sealed cavity is squeezed out.

[0035] Preferably, the power supply device can be started manually or automatically by a control device according to the detection of the smoking behavior of the smoker.

[0036] Preferably, during the smoking cycle of a cigarette, the conduction frequency of the coil 8 can be adjusted.

[0037] Preferably, during the smoking cycle of a cigarette, the current and / or voltage of the coil 8 when it is turned on can be adjusted so that the magnetic force generated by the electromagnet changes from weak to strong, so as to apply a squeezing force from weak to strong to the sealing sleeve 3. This changing force is more in line with the needs of the smoking process. Because when the cigarette is just started to be smoked, the amount of smoke is sufficient and it is easy to be squeezed out. When the cigarette is about to be finished, the amount of smoke is insufficient and a stronger squeezing force is required.

[0038] The conduction frequency of the electromagnet is adjustable from 0.033 to 0.5 Hz.

[0039] The above technical solutions can be freely combined under the premise of no contradiction.

[0040] The principle of the present invention is as follows:

[0041] When the central heating element 1 of the present invention is powered on and operates at the highest temperature, the system temperature no longer rises, the existing smoke pressure in the sealed cavity no longer rises, the aerosol is "confined" or "sealed" in the sealed cavity, and the vibrating smoke outlet component starts to work.

[0042] When the system detects that the smoker starts to inhale, the electromagnet is energized, and under the action of the electromagnetic force, the vibration block 4 starts to reciprocately squeeze the side wall of the sealing sleeve 3, so that the aerosol temporarily "sealed" in the sealing cavity is squeezed and oscillated by the vibration block 4, and a larger dose is squeezed out of the sealing cavity, thereby generating an aerosol of sufficient concentration that can be used for inhalation, which is mixed with air in the filter section of the cigarette to form the smoke that the smoker finally obtains.

[0043] The present invention has the following beneficial effects:

[0044] 1. The general heating method of sealing the gap between the sealed cavity and the cigarette can increase the heating temperature of the cigarette, but because there is no fresh airflow flowing through the tobacco section, the smoke will be "confined" in the sealed cavity. The heating tobacco device of the present invention adopts the method of circumferentially extruding the flexible sealed cavity for the first time to achieve oscillating smoke discharge. At the same time, the upper end of the flexible sealed cavity has a clamping ridge that can clamp and circumferentially seal the cigarette. Therefore, the present invention solves the above problems and simultaneously achieves sealed heating of the cigarette and smooth flow of smoke.

[0045] 2. The present invention uses a flexible sealing cavity and cooperates with circumferential extrusion, a non-insertion sealing cavity method, to disturb the airflow without destroying the sealing performance of the sealing cavity.

[0046] 3. When the heating tobacco device of the present invention is used in conjunction with a general cigarette, it can play the role of clamping and fixing the cigarette to prevent the cigarette from falling from the sealed accommodating cavity. When the heating tobacco device of the present invention is used in conjunction with an oxygen-deficient heating cigarette, the flexible clamping ridges will seal the sealed cavity and clamp the cigarette, and external oxygen will not enter the sealed accommodating cavity. The oxygen content of the tobacco segment will be reduced during inhalation, and the heating temperature of the cigarette can be increased without worrying about the cigarette burning, which can increase the release of tobacco aroma components.

[0047] 4. Since the main clamping parts are the clamping ridges and the sealing ring, the inner diameter after clamping can adapt to the outer diameter of the cigarette. Therefore, one type of smoking device can be adapted to cigarettes of various diameters and can achieve the best clamping and sealing effects.

[0048] 5. The present invention uses a rigid sealing ring with ridges for the first time to make the inner wall of the sealing sleeve have clamping ridges, and the clamping ridges are used to seal the cigarette. The sealing ring also has the function of supporting the sealing sleeve to ensure that the embedded flexible sealing sleeve 3 has a relatively certain geometric size and can be positioned and installed in the smoking device. Compared with the sealing method of setting a separate sealing ring on the sealing sleeve, the present invention is simpler and more practical, and there is no need to worry about the sealing ring falling off.

[0049] 6. When the present invention is actually used, the clamping ridges on the inner wall of the sealing sleeve can only provide compression deformation, and the clamping support of the cigarette mainly depends on the sealing ring. Therefore, there is no requirement for the support strength of the sealing sleeve, and the sealing sleeve can be made of a wider range of materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] The content of the present invention is further explained below through specific implementation examples.

[0057] Example 1

[0058] like Figure 1 As shown, a flexible sealed heating smoking device comprises a sealing heating component and a vibrating smoke outlet component;

[0059] The sealed heating assembly comprises:

[0060] A flexible sealing sleeve 3, the interior of which is a sealing cavity, the upper end of the sealing sleeve 3 is a semi-enclosed "C"-shaped sealing cavity port 33, the opening of the "C"-shaped sealing cavity port 33 is away from the sealing cavity, and a rigid sealing ring 5 with a rigid ridge 51 on the outer surface is arranged inside the cavity of the "C"-shaped sealing cavity port 33, and the rigid ridge 51 on the sealing ring 5 is arranged toward the side wall of the sealing sleeve 3, so that the inner wall of the sealing cavity has a raised clamping ridge 34;

[0061] A central heating element 1, which is arranged inside the sealed cavity;

[0062] The main body of the flexible sealing sleeve 3 is a hollow cylinder with a sealed cavity inside. The sealing sleeve 3 is molded from high temperature resistant non-toxic and tasteless silicone rubber. At the upper end with a larger outer diameter, the inner circular cavity contains a semi-closed "C"-shaped sealed cavity port 33, inside which a metal sealing ring 5 of the same size as the "C" shape can be embedded. During installation, the elasticity and flexibility of the sealing sleeve 3 can be used to embed the sealing ring 5 into the "C"-shaped cavity of the sealed cavity port 33, so as to ensure that the rubber sealing sleeve 3 has a relatively certain geometric size after embedding, and can be positioned and installed in the smoking device.

[0063] The base 2 is arranged at the lower part of the flexible sealing sleeve 3 to support the central heating element 1. There is relative airtightness between the heating needle and the base 2. There is also good relative airtightness between the base 2 and the sealing cavity.

[0064] The inner diameter of the sealed cavity port 33 is D1. The clamping ridge 34 protrudes relative to the side wall of the sealed cavity and has an inner diameter of D2. The size of D2 is approximately (D1-0.25) to (D1-0.03). D1 is the nominal diameter of the smokeable cigarette of the smoking device of the present invention, and the dimensional tolerance is a positive tolerance of 0 to 0.10, so that the cigarette can be easily inserted into the sealed cavity. The cigarette head reaches Figure 1 When the clamping ridge 34 has an inner diameter of D2, since the clamping ridge 34 and the sealing sleeve 3 are made of the same material, which is softer than the sealing ring 5, when the cigarette is further inserted, the clamping ridge 34 is deformed, and the actual aperture of D2 will be slightly larger, just to achieve the purpose of further clamping the filter part of the cigarette. Combined with the sealing of the sealing cavity and the heating effect of the central heating element 1, the purpose of heating the cigarette with less oxygen or less oxygen can be achieved.

[0065] like Figure 2 and Figure 3 As shown, the vibration smoke outlet assembly includes a vibration block 4, an iron core 7, a coil 8, a sealing cavity gasket 22, etc., and the specific design is as follows:

[0066] The middle part of the outer circle of the sealed cavity is a vibration smoke outlet assembly. One side of the outer circle of the sealed cavity is composed of a "C"-shaped ring-shaped, steel, ferromagnetic vibration block 4 to form a striking part.

[0067] The vibration block 4 is positioned between the sealing sleeve 3 and the vibration block 4 by 2 to 3 positioning pins 31 fixedly connected to the sealing sleeve 3, wherein the positioning pins 31 and the vibration block 4 are loosely matched, and a small amount of graphite powder is coated between them, which is lubricating, high temperature resistant, non-toxic and odorless, and convenient for the radial vibration of the vibration block in the sealing sleeve 3. The positioning pins 31 are provided with anti-slip caps 32, which can facilitate connection during installation and prevent slipping during normal use.

[0068] The other side of the outer circle of the sealed cavity is composed of a sealed cavity pad 22 which is fixedly connected to the base 2 and has the functions of heat insulation and side wall support. The middle of the upper part of the sealed cavity pad 22 also has an iron core groove 21 for limiting the position of the iron core 7. There is a symmetrical hole 23 on the left and right sides of the sealed cavity pad 22. The size and shape of the hole 23 are the same as the two ends of the iron core 7. The two ends of the iron core 7 are inserted into the hole 23. The outside of the hole 23 is provided with a screw for fastening the iron core 7 (only the center line is shown in the figure), or other clamping devices, etc., the purpose is to clamp and fix the two ends of the iron core 7 inserted therein at a position where the distance between the end of the iron core and the two ends of the end of the vibration block 4 is L. Wherein L can be adjusted between 0.05-1.00mm, so that the vibration block 4 can cooperate with the cigarette in the rubber sealing sleeve 3. When the heating cavity works to the stable heating range, it can "hit" or "squeeze" the cigarette in the sealed cavity, which has a significant effect on promoting the discharge of the heated smoke aerosol in the sealed cavity.

[0069] In view of the fact that the maximum electromagnetic force of the electromagnet is limited when the power supply of the smoking device is determined, the surface of the vibration block 4 facing the sealing cavity has a plurality of dot-shaped and line-shaped protrusions 41. This reduces the area of ​​direct contact between the vibration block 4 and the sealing sleeve 3, and improves the effect of "hitting" or "squeezing" the cigarette.

[0070] Example 2

[0071] The method of using the flexible sealed heating smoking device of Example 1 is as follows:

[0072] 1. Cigarette insertion stage: When the cigarette to be smoked is inserted into the smoking device from the sealed cavity port 33, the clamping ridge 34 is deformed to clamp the cigarette and circumferentially seal the sealed cavity.

[0073] 2. Suction stage: start the central heating element 1, then start the power supply device, the vibration block 4 starts to reciprocate and squeeze the side wall of the sealing sleeve 3, and the smoke in the sealing cavity is squeezed out.

[0074] When the cigarette is heated from the ambient temperature to the highest temperature at the beginning of the heating period, the air carried by the tobacco in the cigarette is quickly heated, the pressure increases rapidly, and together with the smoke aerosol generated by the high temperature, it is transferred to the filter part of the cigarette to form smoke. When the tobacco is slightly cooled from the highest temperature to the stable constant temperature working section, the remaining air in the tobacco of the cigarette is less, and coupled with the "tightening" effect of the clamping ridge 34, there is no advantage of high pressure to form overflowing smoke. At this time, the electromagnet mainly composed of the iron core 7 and the coil 8, the vibration block 4, and the sealing cavity pad 22 with both heat insulation and lining functions together form the vibration smoke outlet component of the middle and lower sections of the cigarette smoking.

[0075] In addition, the device timely detects the smoker's puffing, and when the heating temperature of the smoking device reaches the stable heating stage, the electromagnet is timely turned on, and the voltage or current of the conduction is controlled by the circuit, and the electromagnetic force is also increased from weak to strong according to the principle of first slightly weak and then slightly strong, so as to give the sealed cavity a continuous squeezing force that matches the puffing. During the stable heating puffing time of a cigarette, the squeezing force gradually increases from weak to strong, so that the smoke squeezed out continuously can ensure the whole process of smoking a cigarette, so that consumers who use the present invention have a very good experience.

[0076] Example 3

[0077] like Figure 4 , Example 3 is another implementation scheme in which the sealing ring 5 is installed from the outside. The upper end of the sealing sleeve 3 is a semi-enclosed "C"-shaped sealing cavity port 33, and the opening of the "C"-shaped sealing cavity port 33 faces downward. Its actual effect on the cigarette is consistent with that described in Example 1, but the appearance is neater, and it is easy to keep the appearance of the smoking device in a better state.

[0078] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
