Description

Aerosol generating product with cooling and plugging functions and cigarette

Technical Field

The invention belongs to the field of heating cigarettes, and particularly relates to an aerosol generating product with cooling and plugging functions and a cigarette.

Background

With the improvement of living standard, people pay more attention to health problems of themselves, and in recent years, attention to smoking health problems is high. In order to meet the changing consumption demands, various heating nonflammable cigarettes for replacing the traditional cigarettes are developed in various enterprises at home and abroad. The heating non-burning cigarette is smoke generated by a smoke generation section of the heating cigarette, the acceptance of the taste of the generated smoke is good, and the heating non-burning cigarette currently marketed mainly comprises the smoke generation section, a hollow support section, a cooling section and a filter tip section. The tobacco in the smoke section is in the form of orderly or unordered filled reconstituted tobacco sheets, cut tobacco, granular tobacco materials, blocky tobacco materials and the like. When the tobacco in the smoke generating section is heated, the essence and the spice loaded on the tobacco and the smoke generating agent are evaporated to generate smoke.

When the smoke section is filled with tobacco particles, the smoke particle section in the cigarette or the cigarette bullet is filled with the tobacco particles, the far lip end of the smoke particle section is sealed by a sealing film, and the near lip end of the smoke particle section is sealed by a sealing piece with holes. The foraminiferous shutoff piece is used for shutoff fuming particle to prevent leaking, allows the flue gas circulation simultaneously.

In the particle heating type cigarette, the average diameter of fuming particles is generally controlled to be about 1.5-0.8 mm, and the plugging piece plays a role in plugging, and the vent hole at the front end of the structure of the particle heating type cigarette is required to be smaller than 0.8mm, and is generally about 0.3-0.6 mm. Therefore, the small holes distributed in the array of the size of the level are machined and manufactured at the front end of the plugging piece, so that the design and manufacturing process difficulty and the manufacturing cost are increased. Although the method of prefabricating the mould can be used to increase the working efficiency and reduce the manufacturing cost, it may not necessarily be an optimal implementation. On the other hand, to increase the smoke volume of a cigarette, even with an array of ventilation apertures, there is a potential for some of the smaller particles to clog, which can affect the overall smoke volume and the consumer's smoking experience.

In addition, to change the smoke amount of the cigarette or increase the smoke amount, the smoke amount is generally realized by punching holes in a hollow supporting section or a cooling section of the cigarette, and a plurality of small holes are added on the diameter of the small-size cigarette, so that the manufacturing difficulty and the manufacturing cost are increased, and meanwhile, the difficulty of adjusting the ventilation degree of the cigarette is brought.

The present invention has been made to solve the above problems.

From "distal" to "proximal" is noted as going from upstream to downstream.

The technical proposal can be freely combined on the premise of no contradiction.

Compared with the prior art, the invention has the following beneficial effects:

1. The distal lip end plugging piece of the aerosol generating product is provided with the open elastic valve 02, the open elastic valve 02 is provided with at least one membrane flap, the center of the open elastic valve 02 is provided with the heating element insertion port 01, and the thickness of the open elastic valve 02 is 1/20-1/2 of the thickness of the distal lip end plugging piece, so that the open elastic valve 02 can ensure the self-adaption to the existing sheet-shaped, cross-shaped or needle-shaped heating element by utilizing the elasticity of the open elastic valve 02, and the flexible insertion of the heating element is facilitated. The open elastic valve 02 is able to enclose the stored particulate smoking material and penetrate into the air when no heating body is inserted. When the heating body is inserted, the open elastic valve 02 can well receive the heating body into the tube body 0 for normal heating.

In addition, the near-lip end plugging device of the aerosol-generating article of the invention has a hollow cavity 6, and two ends realize smoke circulation through the input hole 21 and the output hole 11. The gas flowing in from the input hole 21 at high speed in the near-lip end plugging device II drives the surrounding relatively static gas to generate various complex microcirculation such as vortex, turbulence and the like, so that the gas flow in the near-lip end plugging device II after entering more fully exchanges heat in the near-lip end plugging device II to achieve new balance of heat, pressure and flow velocity, and then the gas is output from the output hole 11, thereby reducing heat in a certain range, balancing pressure and flow velocity. In addition, the inner surface of the near-lip end plugging device II is larger, and the heat radiation of part to the flowing high smoke gas can be properly absorbed to a certain extent, so that a certain cooling effect is achieved, and therefore the structural requirement of a hollow cooling section III matched with cigarettes or cartridges is further reduced, and the length of the hollow cooling section III can be shortened.

2. In the preferred technical scheme, the near-lip end plugging device II is additionally provided with the front air duct 23 and/or the rear air duct 13, so that the path length of the smoke flowing through the near-lip end plugging device II is prolonged, the residence time of the smoke in the near-lip end plugging device II can be prolonged, the effects of absorbing heat, reducing temperature and homogenizing air flow pressure are achieved on the smoke, and the comfort of a user when sucking the smoke is improved.

3. In the preferred technical scheme, can be convenient in the near-lip end plugging device II pack the fragrant cotton that stores up, store up fragrant cotton not only can be to the gas flavoring, the fragrant substance that stores up in the fragrant cotton absorbs the heat of gas and volatilizes, also plays the cooling effect to the gas, has increased the comfort when the user smokes the gas.

4. In the preferred technical scheme, the side wall of the near-lip end plugging device (II) is provided with a vent hole 51, and the outer wall of the cigarette bullet or the cigarette is also provided with a vent hole communicated with the vent hole 51, so that external air can enter the near-lip end plugging device II to cool the flue gas in the hollow cavity 6 of the near-lip end plugging device II.

5. In a preferred embodiment, each flap of the open elastic valve 02 transitions smoothly from thin to thick from the center to the edge near the insertion hole of the heating element. The self-adaptive capacity of the membrane flap and the inserted heating element can be further enhanced, and the self-adaptive capacity of the membrane flap and the inserted heating element has excellent containing and plugging functions on the stored granular fuming material. Meanwhile, the edge of the open elastic valve 02 is thicker, is not easy to tear, and is easy to form and fill.

6. The aerosol generating product combines the functions of the existing particle type product on the storage and the isolation plug of the particle smoke material, can be directly used on a paper tube or a corresponding device with the functions of cooling and filtering, and changes the structure of the existing particle type smoke product. Of course, the aerosol-generating article of the invention may also be used as a cartridge, directly in a mouthpiece-containing smoking article.

7. The independently formed aerosol generating product capable of being heated and atomized to form aerosol can contain different tastes of fuming particles, and the fuming particles and the empty smoke tubes with different colors and or paper designs are matched with a specially designed heating device, so that consumers can have various flexible and changeable use modes, the fixed use mode of the existing particle type product is changed, and the product possibly gains the favor of more consumers.

8. At the same time, the empty smoke pipe part can be reused, and when the empty smoke pipe is used each time, only the aerosol generating product needs to be disassembled to replace the aerosol generating product part. Therefore, the invention transfers the adverse factors of long production process and long processing period of the granular heating fuming product formed by the existing one complete paper tube into the manual experience of DIY of consumers. The method not only mobilizes the enthusiasm of the consumer which can play and suck, has brand new consumption experience, but also can properly shorten the processing period of single cigarette of the producer, thereby realizing the win-win effect of 'producing and eliminating'. Of course, the novel granular cigarette with a new structure used with the fixed smoke tube can also be produced, and the product series of granular heating atomized products are enriched.

Example 1

Referring to fig. 1, an aerosol-generating article comprises a tube 0;

wherein the tube body 0 accommodates therein a particulate aerosol-generating substance;

the proximal lip end of the pipe body 0 is connected with a proximal lip end plugging device II, and the distal lip end of the pipe body 0 is provided with a distal lip end plugging piece;

in this embodiment, the proximal lip occlusion device II is designed as follows:

the near lip end plugging device II comprises a cup-shaped front plugging piece 2 and a cup-shaped rear plugging piece 1;

Wherein, the cup bottom of the cup-shaped front plug 2 is provided with two input holes 21;

The center of the cup bottom of the cup-shaped rear plug 1 is provided with an output hole 11;

The cup openings of the cup-shaped front blocking piece 2 and the cup-shaped rear blocking piece 1 are opposite and detachably connected, and a hollow cavity 6 is formed in the near-lip end blocking device.

The pipe body 0 and the near-lip end plugging device II are made of high-temperature resistant silica gel and are integrally formed through an injection molding process.

The cup-shaped front plug 2 and the cup-shaped rear plug 1 are detachably connected through the side walls of the respective cup-shaped structures. Specifically, the side wall end of the cup-shaped structure of the cup-shaped front plug 2 has a front cylindrical extension 22 extending axially. The front cylindrical extension 22 forms an annular recess a inside the cup-shaped front plug 2. The cup-shaped back plug 1 has an axially extending back cylindrical extension 12 at the end of the cup-shaped side wall, the back cylindrical extension 12 forming an annular recess B outside the cup-shaped back plug 1.

The front and rear cylindrical extensions 22, 12 transition or interference fit to achieve the coupling of the cup-shaped front and rear plugs 2, 1 into the proximal lip occlusion device II of fig. 2. The whole length L of the near-lip end plugging device II is larger than the maximum outer diameter D (namely the length-diameter ratio L/D is larger than 1) of the near-lip end plugging device II so as to prevent the near-lip end plugging device II from side turning and blocking when being put into a smoke tube, and the production efficiency is influenced.

The cup-shaped front plug 2 is internally provided with a front air duct 23 which is integrated with the cup-shaped front plug, and the front air duct 23 is coaxially arranged with the outer tube wall of the cup-shaped front plug 2. The front air duct 23 is a hollow column. The axial length of the leading air tube 23 is smaller than the length of the hollow cavity 6 of the proximal lip end plugging device II so as to reserve the space for the outflow of air.

A rear air duct 13 integrally connected with the cup-shaped rear plug 1 is also added in the cup-shaped rear plug. The rear air duct 13 is also arranged coaxially with the outer tube wall of the cup-shaped rear plug 1. The axial length of the rear air duct 13 is smaller than that of the hollow cavity 6 of the proximal lip end plugging device II so as to reserve a space for the outflow of air.

The outer diameter of the rear air duct 13 is smaller than the inner diameter of the front air duct 23, so that a part of the rear air duct 13 is positioned in the front air duct 23 with a sufficient ventilation gap left therebetween.

In this embodiment, as can be seen in fig. 1b, the distal lip closure is designed as follows:

The distal lip end of the tube body 0 is a layer of integrally molded end face 03. The end face 03 acts as the distal lip closure. The central part of the end face 03 is provided with a "+" shaped slit. The "+" shaped slit serves as a through hole. The distal lip end of the end face 03 is provided with a layer of thinner silicone open elastic valve 02 around the "+" shaped slit. The open elastomeric valve 02 is also integrally molded with the end face 03.

The open elastic valve 02 is the extension of the transition area between the end face 03 and the "+" shaped gap, is different from the thickness of the end face 03 in thickness, and is connected with the end face 03 by an arc, so that the open elastic valve can adapt to heating elements with different shapes and can well block granular fuming materials stored in the pipe body 0 from leaking out of the pipe body 0. The end face 03 has a recess that matches the shape of the open elastomeric valve 02 to accommodate the open elastomeric valve 02 such that the open elastomeric valve 02 is substantially planar with the remainder of the end face 03.

The open elastic valve 02 is provided with four membrane flaps which are combined together to form a cross shape, and a cross-shaped heating element insertion port 01 is arranged in the center of each of the four membrane flaps. The through hole in the central portion of the end face 03 is located opposite to and penetrates the heating element insertion port 01, so that the heating element is inserted.

The thickness of the end face 03 is m and 0.4 to 1.5mm. In the open elastic valve 02, the thickness n of the valve is preferably 0.1-0.3 mm, at most not more than 0.5mm, at the edge of the center of the thinnest valve. The width p of the "+" shaped heating element insertion opening 01 is recommended to be 0.01-0.2 mm. The width of each flap is q, preferably 1.5-5 mm. The open elastic valve 02 is uniform in thickness or increasing in thickness from the center to the edge of the "cross" shaped heating element insertion port 01.

The purpose of arranging the open elastic valve 02 is that the open elastic valve 02 can ensure the self-adaption of the existing sheet-shaped, cross-shaped or needle-shaped heating element by utilizing the elasticity of the silica gel, and the heating element can be conveniently and flexibly inserted. The open elastic valve 02 is able to enclose the stored granular material and penetrate into the air without the insertion of a heating body. When the heating body is inserted, the open elastic valve 02 can well receive the heating body to enter the pipe body 0 for normal heating.

Of course, the choice of heating body type for heating the particle storage device of the invention can be flexibly selected depending on the diameter of the cigarette. When heating bodies of other geometric shapes are to be inserted, the intermediate heating element insertion opening 01 and the open elastic valve 02 can also be correspondingly changed in a targeted manner, and are also in the protection of the invention.

The two ends of the tube body 0 are provided with chamfer or arc transition which is easy to be installed (or inserted) so as to ensure better delivery or installation and use. The inner wall of the tube body 0 is provided with an inner flange 04 to limit the proximal lip end blocking device. After the proximal lip blocking device is inserted into the tube body 0, the cup-shaped front blocking member 2 abuts against the inner flange 04. The cup-shaped rear plug 1 of the plug II is exposed with respect to the pipe body 0.

Fig. 2 is a cigarette comprising the aerosol-generating article of fig. 1 described above and a tube of smoke inserted into the aerosol-generating article. The aerosol generating product is provided with a plug-in connection part which is plugged with the smoke tube. Specifically, in fig. 1, the cup-shaped rear plug 1 is exposed with respect to the pipe 0, thereby forming an inward concave table as an insertion portion.

The smoke tube comprises a cooling section III which is abutted with the aerosol generating product and a filtering section IV which is arranged at the downstream of the cooling section.

Example 2

An aerosol-generating article differs from example 1 in that the front air duct 23 and the rear air duct 13 are replaced by a coaxial core 3 arranged within the hollow cavity 6 of the closure, as shown in figure 3. The cup-shaped front plug 2 has a front cylindrical extension extending from the upper end of the side wall of the cup-shaped structure. The front cylindrical extension forms an annular recess a inside the cup-shaped front plug 2. The lower end of the side wall of the cup-shaped structure of the cup-shaped rear plug 1 is provided with a rear cylindrical extension part which extends out, and the rear cylindrical extension part forms an annular concave table C inside the cup-shaped rear plug 1. The coaxial core 3 is in interference fit connection with the cup-shaped rear plug 1 and the cup-shaped front plug 2 at the middle annular concave station A and the annular concave station C.

The coaxial core 3 is composed of a hollow inner cylinder 32 and a hollow outer cylinder 34 which are coaxially arranged. The upper end face of the coaxial core 3 is open, and the lower end face has 2 or more outer through holes 31. The 2 outer through holes 31 are radially positioned between the side wall of the hollow inner cylinder 32 and the side wall of the hollow outer cylinder 34. The coaxial core 3 is arranged in the middle of the hollow cavity 6 of the proximal lip end plugging device II so that the outer through hole 31 communicates an annular space 35 between the side wall of the hollow inner cylinder 32 and the side wall of the hollow outer cylinder 34 with the interior of the cup-shaped front plugging member 2. The hollow inner cylinder 32 is provided with 2 inner through holes 33 on the side wall thereof to communicate the annular space 35 with the space inside the hollow inner cylinder 32. The hollow inner cylinder 32 communicates internally with the outlet aperture 11.

Specifically, the annular space 35 between the side wall of the hollow inner cylinder 32 and the side wall of the hollow outer cylinder 34 communicates with the input hole 21 only through the outer through hole 31.

When the lip-end closing device II works, smoke enters from the input hole 21 of the cup-shaped front closing piece 2, and under the suction pressure of a smoker, the smoke enters the annular space 35 between the side wall of the hollow inner cylinder 32 and the side wall of the hollow outer cylinder 34 through the outer through hole 31, then the smoke enters the space inside the hollow inner cylinder 32 through the inner through hole 33, and is output to the next cavity of a cigarette or a cigarette cartridge from the output hole 11. In the process, the flue gas moves axially and radially for a plurality of times in the whole baffling blocking piece II, so that baffling movement is realized. In the process, the residence time of the smoke in the whole near-lip end plugging device II is prolonged, and the smoke is cooled.

In addition, in the above process, when the flue gas flows in the near-lip end plugging device II, through a plurality of small holes, the space with a plurality of volume changes is passed through, the volume changes cause the pressure changes, and then the pressure difference is generated, and under the action of the pressure difference, the inside of the near-lip end plugging device II generates multi-area micro-flow, and the heat and the pressure difference are homogenized. In addition, the design also increases the mixing degree of the smoke, homogenizes the temperature, the concentration and the like of the smoke, and increases the comfort of the user when the user sucks the smoke.

Fig. 4 is a particulate cigarette comprising the aerosol-generating article of fig. 3 described above and a tube of smoke inserted into the aerosol-generating article. The aerosol generating product is provided with a plug-in connection part which is plugged with the smoke tube. Specifically, in fig. 3, the cup-shaped rear plug 1 is exposed with respect to the pipe 0, thereby forming an inward concave table as an insertion portion. The smoke tube comprises a cooling section III which is abutted with the aerosol generating product and a filtering section IV which is arranged at the downstream of the cooling section.

The cup-shaped front plug 2 is provided with 8 circumferentially distributed input holes 21. The cup-shaped back plug 1 is provided with 8 output holes 11 which are distributed circumferentially. The cup-shaped front plug 2 has a front cylindrical extension extending from the upper end of the side wall of the cup-shaped structure. The front cylindrical extension forms an annular recess a inside the cup-shaped front plug 2. The lower end of the side wall of the cup-shaped structure of the cup-shaped rear plug 1 is provided with a rear cylindrical extension part which extends out, and the rear cylindrical extension part forms an annular concave table C inside the cup-shaped rear plug 1.

And a petal core 4 is respectively arranged at the upstream of the cup-shaped front sealing piece 2 and the downstream of the cup-shaped rear sealing piece 1. Therefore, the side of the sealing piece II is not required to be preferentially oriented to fuming particles during assembly, so that the device is more convenient to use for automatic production, the investment of technological equipment such as a mould in the initial research and development stage of the device can be reduced, the automatic production can be facilitated, and the device is a more optimized, feasible and innovative technical scheme.

The specific structure of the petal core 4 is as follows:

As shown in fig. 5a and 5c, a positioning core 43 is provided at the center of the petal core 4. The center of the cup bottom of the cup-shaped front plug 2 is provided with a front positioning hole 22. The front locating hole 22 coincides with the outer contour of the locating core 43 and both are interference fit.

The petal core 4 further comprises four rib plates 42 which are arranged in a cross mode in a shape of a Chinese character 'mi', and the positioning cores 43 are fixedly connected to the cross parts of the rib plates 42. The tail end of each rib plate 42 is respectively connected with 2 cylindrical sealing heads 41. The front end of the cup-shaped front plug 2 is provided with a "rice" -shaped recess, not shown in fig. 5, which cooperates with the rib plate 42. Four rib plates 42 which are arranged in a cross manner in a shape like a Chinese character 'mi' are arranged in the grooves in a shape like a Chinese character 'mi' to ensure that after the petal cores 4 are axially positioned by the positioning cores 43 in the center, each cylindrical seal head 41 is ensured to be at the correct circumferential position in the middle of the input hole 21 or the output hole 11 so as to obtain balance, and an annular gap with the interval smaller than the average particle size of the granular fuming materials is formed between the outer wall of the seal head 41 and the inner wall of the input hole 21 or the output hole 11. The annular gap serves as an air flow passage.

Likewise, in example 1, the front air duct 23 and the rear air duct 13 were replaced with the central transverse partition column 5 provided in the hollow cavity 6 of the proximal lip occlusion device II. The central transverse partition column 5 is a hollow cylinder, and a transverse partition plate is arranged inside the central transverse partition column. The diaphragm divides the entire proximal lip occlusion device II from the middle into two parts, a front cavity 61 and a rear cavity 62. The diaphragm has a vent 51. The central transverse partition column 5 is in interference fit connection with the cup-shaped rear plug 1 and the cup-shaped front plug 2 at the middle annular concave platform A and the annular concave platform C, and the central transverse partition column, the cup-shaped rear plug 1 and the cup-shaped front plug 2 are assembled together to form a complete near-lip end plugging device II.

The cigarette structure provided by the embodiment is shown in fig. 6, and comprises the aerosol-generating product and a cigarette tube spliced with the aerosol-generating product. The aerosol generating product is provided with a plug-in connection part which is plugged with the smoke tube. The smoke tube comprises a cooling section III and a filtering section IV.

Example 4

In the aerosol-generating article shown in fig. 7, the difference from example 3 is that the specific structure of the petal core 4 is as follows:

the petal core 4 comprises 8 rib plates 42 and 8 cylindrical sealing heads 41 which are arranged at intervals. Two ends of each rib plate 42 are respectively connected with one sealing head 41. Two webs 42 are also attached to each head 41. The 8 rib plates 42 and the 8 seal heads 41 are mutually connected to form a circular or polygonal perimeter part.

Each cylindrical closure 41 is received in the correct position in the middle of the inlet aperture 21 or outlet aperture 11 to achieve a balance in which an annular gap is formed between the outer wall of the closure 41 and the inner wall of the inlet aperture 21 or outlet aperture 11 at a distance less than the average particle size of the particulate smoking material. The annular gap serves as an air flow passage.
