[0002] With the continuous development of tobacco industry, the demand of consumers for tobacco products is increasingly diversified, and heating not burning cigarette is one of the development directions. The heating not burning cigarette is prepared by crushing and reconstituting tobacco raw materials to prepare suitable smoke releasing materials. Tobacco particles are one of the smoke releasing materials, which have the advantages of clean smoke and simple production. However, the tobacco particles will inevitably flow downstream under the disturbance of airflow during the smoking process. Therefore, a fixing part must be arranged downstream of the tobacco particles in the traditional particle type heating cigarette rod structure to limit the particles and achieve the effect of separating the particles from the smoke. At present, the fixing part is usually arranged as a gear-shaped hard plastic, which not only increases the production cost, but also is not conducive to the release of smoke.

[0051] Figure 2 The axial side view of the smoking set of the first embodiment.

[0052] As Figures 1-2 The first embodiment of the present application provides a heating smoking set, which comprises an upper constant-diameter cylinder 4 and a lower inner-diameter-gradually-changing cylinder 5.

[0053] The inner diameter of the inner-diameter-gradually-changing cylinder 5 gradually increases from bottom to top.

[0054] The upper end inner diameter of the inner-diameter-gradually-changing cylinder 5 is equal to the inner diameter of the constant-diameter cylinder 4, and the bottom of the inner-diameter-gradually-changing cylinder 5 is sealed.

[0055] The top surface of the constant-diameter cylinder 4 has a cigarette insertion port, and the area of the top surface of the constant-diameter cylinder 4 other than the cigarette insertion port is sealed.

[0056] The side wall of the constant-diameter cylinder 4 has an air inlet 9.

[0057] The constant-diameter cylinder 4 and the inner-diameter-gradually-changing cylinder 5 are in airflow communication.

[0058] The heating element is a circumferential heating element 3 arranged around the inner-diameter-gradually-changing cylinder and a bottom heating element 6 arranged at the bottom of the inner-diameter-gradually-changing cylinder.

[0059] The heating smoking set further comprises a detachable baffle 1 arranged at the bottom of the inner-diameter-gradually-changing cylinder, which is used to seal the bottom of the inner-diameter-gradually-changing cylinder 5 and prevent tobacco particles from falling out during use. Of course, the sealing can also be achieved by arranging the bottom heating element 6 at the bottom of the inner-diameter-gradually-changing cylinder 5.

[0060] The constant-diameter cylinder 4 and the inner-diameter-gradually-changing cylinder 5 are fixedly connected or detachably connected.

[0061] The design of the cigarette insertion port facilitates the user to easily insert a cigarette or a filter segment 8.

[0062] The constant-diameter cylinder 4 is preferably a hollow cylinder. The inner-diameter-gradually-changing cylinder 4-1 is preferably a circular truncated cone.

[0063] The second embodiment of the present application provides a heating cigarette system, which comprises a cigarette and a heating smoking set; the cigarette comprises a filter segment 8, and the filter segment 8 is inserted into the cigarette insertion port.

[0064] The cigarette further comprises a cooling segment 7 connected to the filter segment 8.

[0065] The cigarette further comprises a smoking particle segment directly or indirectly connected to the filter segment 8, and the bottom of the smoking particle segment is sealed by a heat-shrinkable sealing film.

[0066] The third embodiment of the present application provides another heating cigarette system, which comprises a cigarette and a heating smoking set; the cigarette comprises a filter segment 8, and the filter segment 8 is inserted into the cigarette insertion port.

[0067] The cigarette further comprises a temperature-reducing section 7 connected with the filter section 8. The smoking section can not be designed in the cigarette.

[0068] The fourth aspect of the present application provides a working method of the heating cigarette system of the second aspect, and the working method is as follows:

[0069] The heating device is started, the heating element heats the air in the inner diameter tapered cylinder 5, and performs thermal radiation on the heat-shrinkable blocking film at the bottom of the smoking particle section;

[0070] The heat-shrinkable blocking film is broken after being heated, so that the smoking particles in the smoking particle section fall into the inner diameter tapered cylinder 5, and the smoking particles generate aerosol after being heated;

[0071] After the user starts to smoke through the filter section 8, the air entering through the air inlet 9 generates a spiral airflow in the inner diameter tapered cylinder 5 and mixes with the aerosol, and then changes into an airflow along the central axis of the inner diameter tapered cylinder 5 upwards and is discharged from the filter section 8.

[0072] In the above working method, the traditional granular heating cigarette is still used, but the bottom sealing film of the cigarette is designed as a heat-shrinkable film which can be broken after being heated. At this time, after the cigarette is inserted, the heat-shrinkable film is broken under the heating of the heating element, and the smoking particles 2 fall from the cigarette and are stacked at the lower part of the inner diameter tapered cylinder 5.

[0073] The fourth aspect of the present application provides a working method of the heating cigarette system of the third aspect, and the working method comprises the following steps:

[0074] The heating device is started, and the heating element heats the air in the inner diameter tapered cylinder 5;

[0075] Meanwhile, the smoking particles 2 generate aerosol after being heated;

[0076] After the user starts to smoke through the filter section 8, the air entering through the air inlet 9 generates a spiral airflow in the inner diameter tapered cylinder 5 and mixes with the aerosol, and then changes into an airflow along the central axis of the inner diameter tapered cylinder 5 upwards and is discharged from the filter section 8.

[0077] In the above working method, the traditional granular heating cigarette is not used. The smoking particles 2 are added into the inner diameter tapered cylinder 5 through the detachable baffle 1 or the cigarette insertion port. The bottom heating element 6 can be arranged on the upper part of the detachable baffle 1, and the heating of the smoking particles 2 is realized by heating the air.

[0078] In the present application, the inner diameter of the constant-diameter cylinder 4 remains unchanged, and the airflow rotates at high speed in this space. The cigarette insertion port is located on the upper surface of the constant-diameter cylinder 4, and relative sealing can be realized between the cigarette insertion port and the cigarette.

[0079] The inner diameter of the tapered cylinder 5 gradually increases from the bottom, so that the particles are thrown to the wall by centrifugal force and fall down due to gravity.

[0080] Preferably, the air inlet 9 is flush with the top surface of the constant diameter cylinder 4. Of course, the air inlet can also be lower than the top surface of the constant diameter cylinder 4, but it is preferable that the air inlet 9 is above the lower end surface of the cigarette, so that the mixed gas flow containing aerosol can be discharged from the cigarette.

[0081] Preferably, the air inlet 9 of the constant diameter cylinder 4 is connected with an air inlet pipe. The air inlet pipe extends in a tangential direction of the constant diameter cylinder 4.

[0082] The smoking particle circulation mechanism of the present application is as follows:

[0083] During the smoking process, the airflow enters from the air inlet 9 and forms a circular flow inside the structure of the constant diameter cylinder 4 and the tapered cylinder 5, driving the smoking particles 2 to produce spiral motion, similar to the principle of a cyclone separator, achieving sufficient contact between the smoking particles 2 and the airflow to effectively extract the smoke. However, due to the gravity of the smoking particles 2, the lifting force of the airflow is not enough to completely carry the smoking particles 2 out of the smoking device. This design ensures that the smoking particles 2 fall again after being carried up by the airflow, forming a reciprocating motion. During the smoking process, the movement of the smoking particles 2 in the heating area can maximize the release of smoke generated in the heating state, improving the utilization efficiency of tobacco. In the heating state, the smoking particles 2 remain stationary in the heating area, which is the smoke generation stage.

[0084] Preferably, the diameter of the cigarette insertion port is adapted to the common particle type heated cigarette. A rubber sealing ring is provided around the cigarette insertion port to achieve sealing between the cigarette and the cigarette insertion port.

[0085] In the present application, the detachable baffle 1 is provided at the lower part of the smoking device, which is convenient for cleaning and maintenance, and effectively prevents the smoking particles 2 from falling.

[0086] Preferably, the inner diameter of the tapered cylinder 5 gradually increases from 5 mm at the bottom to 10 mm, forming a heating area suitable for particle settling. The height of this area is 5 cm, ensuring sufficient heating space.

[0087] Preferably, the inner diameter of the constant diameter cylinder 4 is 10 mm, and the length is 5 cm, ensuring good connection between the cigarette and the heating area.

[0088] The heating method of the present application has two types:

[0089] The circumferential heating element: a circumferential heating element 3 is provided inside the heating device, which adopts resistance heating method and can quickly heat to above 200°C. The circumferential heating element is connected to the rechargeable battery through the current control module, and the user can adjust the temperature through the button.

[0090] Hot air heating: bottom heating element 6 is set before the lower baffle of the smoking device, which is resistance heating. During the smoking process, the gas flows through the heating sheet and is fully heated and contacted with the particles, realizing the heating of the tobacco material.

[0091] Particle distribution: when the cigarette is inserted, the tobacco particles will randomly fall into the heating area, i.e. the inner diameter gradually changing cylinder.

[0092] Suction stage:

[0093] When the user starts to smoke, the lift of the main airflow makes the particles spiral in the heating area with the airflow. Due to the gravity of the particles, the lift is not enough to take the particles out of the smoking device completely, and the particles are taken up by the airflow again after falling, forming a circulating motion.

[0094] The above is only to further illustrate the technical content of the present application by way of examples, so that the reader can more easily understand, but not represent the implementation of the present application is limited to this, any technical extension or re-creation made according to the present application, are protected by the present application. The scope of protection of the present application is subject to the claims.
