Description

Aerosol generating product with cooling and blocking functions and cigarette

Technical Field

The utility model belongs to heating cigarette field, concretely relates to aerosol generates goods and cigarette with cooling and shutoff function.

Background

With the improvement of living standard, people pay more and more attention to their health problems, and in recent years, the attention on the health problems of smoking is high. In order to meet the changing consumption requirements of various large enterprises at home and abroad, various heating non-burning cigarettes replacing the traditional cigarettes are developed in a dispute. The heating non-combustion cigarette is characterized in that a smoking section of the heating cigarette generates smoke, the acceptance of the smoke taste generated by the heating cigarette is good, and the current market-oriented heating non-combustion cigarette mainly comprises a smoking section, a hollow supporting section, a cooling section and a filter tip section. The form of the tobacco in the smoking segment is: reconstituted tobacco sheets, tobacco shreds, granular tobacco substances, blocky tobacco substances and the like which are filled orderly or disorderly. When the tobacco in the smoking section is heated, the essence, the spice and the smoke agent loaded on the tobacco are evaporated to generate smoke.

When the smoking section is filled with tobacco particles, the smoking particle section in a cigarette or a smoke cartridge is usually filled with the tobacco particles, the far lip end of the smoking particle section is sealed by a sealing film, and the near lip end of the smoking particle section is sealed by a plugging piece with a hole. The plugging piece with the holes is used for plugging the fuming particles to prevent leakage and simultaneously allows smoke to circulate.

Because the average diameter of fuming particles in the particle heating type cigarette is generally controlled to be about 1.5-0.8 mm, and the plugging piece plays a plugging role, the air vent at the front end of the structure of the particle heating type cigarette is required to be smaller than 0.8mm, and is usually about 0.3-0.6 mm. Therefore, the small holes distributed in the array with the size of the same level are processed and manufactured at the front end of the plugging piece, so that the process difficulty and the manufacturing cost of design and manufacture are increased. Although the method of prefabricating the mold can be used to improve work efficiency and reduce manufacturing cost, it may not be an optimal implementation. On the other hand, to increase the amount of smoke in a cigarette, even if the ventilation holes are distributed in an array, there is a possibility that a part of the smoke will be blocked by smaller particles, which will affect the overall amount of smoke and the smoking experience of the consumer.

In addition, to change the amount of smoke or increase the amount of smoke, the cigarette is generally perforated 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 cost are increased, and the difficulty of adjusting the ventilation degree of the cigarette is brought.

In order to solve the above problems, the utility model is provided.

Example 1

As figure 1, an aerosol-generating article comprising: a pipe body 0;

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

a near lip end plugging device II is connected to the near lip end of the tube body 0, and a far lip end plugging piece is arranged at the far lip end of the tube body 0;

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

the near-labial-end occlusion device II comprises: a cup-shaped front plug piece 2 and a cup-shaped rear plug piece 1;

wherein, the cup-shaped front plug 2 has two input holes 21 at the bottom;

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

the cup-shaped front plug 2 and the cup-shaped rear plug 1 are oppositely and detachably connected with each other, and a hollow cavity 6 is formed inside the near lip end plugging 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 front and rear cup-shaped plugs 2, 1 are detachably coupled by the side walls of the respective cup-shaped structures. In particular, the end of the side wall of the cup-shaped front closure 2 has a front cylindrical extension 22 extending axially. The front cylindrical extension 22 forms an annular recess a inside the cup-shaped front closure 2. The end of the side wall of the cup-shaped structure of the cup-shaped rear plug 1 is provided with a rear cylindrical extension portion 12 extending axially, and the rear cylindrical extension portion 12 forms an annular concave B outside the cup-shaped rear plug 1.

The front cylindrical extension 22 and the rear cylindrical extension 12 are in a transition or interference fit to achieve the coupling of the cup-shaped front closure 2 and the cup-shaped rear closure 1 as the proximal labial end closure device II in 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 that the phenomenon that the side turning and the shell clamping occur when the near lip end plugging device II is installed into a smoke tube and the production efficiency is influenced is prevented.

A front air guide pipe 23 connected with the cup-shaped front plugging piece 2 into a whole is arranged in the cup-shaped front plugging piece 2, and the front air guide pipe 23 is coaxially arranged with the outer pipe wall of the cup-shaped front plugging piece 2. The front air guide tube 23 is a hollow column. The axial length of the front air guide pipe 23 is smaller than the length of the hollow cavity 6 of the near lip end blocking device II, so that a space for gas to flow out is reserved.

The cup-shaped rear plug 1 is also internally provided with a rear air duct 13 which is connected with the cup-shaped rear plug into a whole. The rear gas duct 13 is also arranged coaxially with the outer tube wall of the cup-shaped rear closure 1. The axial length of the rear air duct 13 is smaller than that of the hollow cavity 6 of the near lip end plugging device II, so that a space for gas to flow out is reserved.

The outer diameter of the rear airway tube 13 is smaller than the inner diameter of the front airway tube 23, so that a part of the rear airway tube 13 is positioned in the front airway tube 23, and a gap enough for ventilation is left between the two.

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

the distal lip end of the tube body 0 is an integrally cast end face 03. The end face 03 acts as the distal lip closure. The central portion of the end face 03 is provided with a "+" shaped slit. The "+" shaped slit serves as a through hole. A layer of thinner silica gel open type elastic valve 02 is arranged at the far lip end of the end face 03 around the '+' shaped gap. The open elastic valve 02 is also integrally molded with the end face 03.

The open elastic valve 02 is an extension of a transition area between the end face 03 and a cross-shaped gap, is different from the end face 03 in thickness, is connected with the end face 03 by an arc, can be adaptive to heating elements with different shapes, and can well prevent granular smoking materials stored in the tube body 0 from leaking out of the tube body 0. The end face 03 has a recess matching the shape of the open elastic valve 02 to accommodate the open elastic valve 02 such that the open elastic valve 02 is substantially in the same plane as the rest of the end face 03.

The open type elastic valve 02 is provided with four valve flaps which are combined into a cross shape together, and the center of each of the four valve flaps is provided with a cross-shaped heating element insertion opening 01. The through hole in the central portion of the end face 03 is opposite to and penetrates through the heating element insertion port 01 to insert the heating element.

The thickness of the end face 03 is 0.4-1.5 mm. In the open type elastic valve 02, the thickness n of the valve is preferably 0.1-0.3 mm and at most not more than 0.5mm at the edge of the thinnest valve center. The width p of the insertion opening 01 of the heating element shaped like a plus sign is preferably 0.01 to 0.2 mm. The width of each valve is q, and the recommended width is 1.5-5 mm. The thickness of the open elastic valve 02 is uniform or gradually increased from the center to the edge of the insertion port 01 of the heating element shaped like a cross.

The purpose of the open elastic valve 02 is: so that the open type elastic valve 02 can ensure the self-adaptation to the existing sheet, cross or needle type heating element by utilizing the elasticity of the silica gel, and is convenient for the flexible insertion of the heating element. The open elastic valve 02 can seal the inner storage granular material and penetrate air when the heating body is not inserted. When the heating body is inserted, the open elastic valve 02 can well receive the heating body to enter the tube body 0 for normal heating.

Of course, the heating member type of the particle storage device can be flexibly selected according to the diameter of the cigarette and the heating of the utility model. When a heating body with other geometric shapes needs to be inserted, the middle heating element insertion hole 01 and the open elastic valve 02 can be correspondingly changed in a targeted manner, and the invention is also protected.

Both ends of the pipe body 0 are provided with chamfers or arc transitions which are 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 near lip end plugging device. After the near lip end plugging device is inserted into the pipe body 0, the cup-shaped front plugging piece 2 abuts against the inner flange 04. The cup-shaped rear plug 1 of the plug II is exposed relative to the pipe body 0.

Figure 2 is a tobacco rod comprising the aerosol-generating article of figure 1 above and a tobacco tube to which the aerosol-generating article is attached. The aerosol generating product is provided with a plug-in part which is plugged with the smoke tube. In particular, the cup-shaped rear closure 1 is exposed with respect to the tubular body 0 in fig. 1, thus forming an inwardly concave platform as a plug-in part.

The inside of the smoke tube comprises: a cooling section III in abutment with the aerosol-generating article, a filtration section IV downstream of the cooling section.

The upper end part of the side wall of the cup-shaped structure of the cup-shaped front plug piece 2 is provided with a front cylindrical extension part extending out. The front cylindrical extension forms an annular recess a inside the cup-shaped front closure 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 extending out, and the rear cylindrical extension part forms an annular concave platform C inside the cup-shaped rear plug 1. The coaxial core 3 is connected with the cup-shaped rear plugging piece 1 and the cup-shaped front plugging piece 2 in an interference fit mode at the middle annular concave platform A and the annular concave platform 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 disposed radially between the side walls of the hollow inner cylinder 32 and the hollow outer cylinder 34. The coaxial core 3 is arranged in the middle of the hollow cavity 6 of the near lip end blocking device II so that the outer through hole 31 communicates the 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 inside of the cup-shaped front blocking piece 2. The side wall of the hollow inner cylinder 32 is provided with 2 inner through holes 33 to communicate the annular space 35 with the space inside the hollow inner cylinder 32.
