Description

Technical Field

[0001] The present invention belongs to the field of heat-not-burn tobacco products, and in particular relates to a heating smoking device, a heating cigarette system and a working method thereof. Background Art

[0002] With the continuous development of the tobacco industry, consumers' demands for tobacco products are becoming increasingly diversified, and heat-not-burn cigarettes are one of the development directions. Heat-not-burn cigarettes are made by crushing and regenerating 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, tobacco particles will inevitably flow downstream due to airflow disturbances during the inhalation process. Therefore, in the traditional particle-type heated cigarette cigarette structure, a fixing must be set downstream of the tobacco particles to limit the particles and achieve the effect of separating the particles from the smoke. At present, the fixing is usually set as a gear-shaped hard plastic, which not only increases the production cost, but also is not conducive to the release of smoke.

[0003] In order to solve the above problems, the present invention is proposed. Summary of the invention

[0017] Preferably, the cigarette further comprises: a smoke-generating particle segment directly or indirectly connected to the filter segment, and the bottom of the smoke-generating particle segment is sealed by a heat-shrinkable sealing film.

[0018] Preferably, the inner diameter gradually changing cylinder contains smoke-generating particles.

[0019] A third aspect of the present application provides a working method of a heated cigarette system, the heated cigarette system comprising: a cigarette and the heated smoking device according to any one of the first aspects;

[0022] The working method comprises the following steps:

[0023] The heating smoking device is started, and the heating element heats the air in the gradually changing inner diameter cylinder and radiates heat to the heat-shrinkable sealing film at the bottom of the smoke-generating particle segment;

[0024] The heat-shrinkable sealing film ruptures after being heated, so that the smoke particles in the smoke particle section fall into the inner diameter gradient cylinder, and the smoke particles generate aerosols when heated;

[0025] After the user starts to inhale through the filter segment, the air entering from the air inlet generates a spiral airflow in the inner diameter gradient cylinder and mixes with the aerosol, and then turns into an upward airflow along the central axis of the inner diameter gradient cylinder and is discharged from the filter segment.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] Traditional particle-type heated cigarettes often use gear-shaped fixings to prevent particle flow, which not only prevents the effective extraction and transmission of smoke, but also increases the difficulty and cost of production. The design of the smoking device of the present invention uses aerodynamics to limit the position of particles, while cleverly avoiding the need for physical fixings. This not only helps to simplify the production process and save production costs, but also enables the airflow to contact the particles more completely during the suction process, thereby improving the efficiency of smoke release.

The core of this application design is to optimize the structure, heating method and particle movement mechanism of the smoking device.

[0050] Figure 1 This is a schematic diagram of the smoking device structure of the first embodiment.

[0051] Figure 2 This is an axial side view of the smoking device of the first embodiment.

[0052] like Figure 1-2 The first embodiment of the present application provides a heating smoking device, the heating smoking device comprising: an upper constant diameter cylinder 4 and a lower inner diameter gradual cylinder 5;

[0053] Wherein, the inner diameter of the inner diameter gradual change cylinder 5 gradually increases from bottom to top;

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

[0055] The top surface of the equal-diameter cylinder 4 is provided with a cigarette insertion opening, and the area of ​​the top surface of the equal-diameter cylinder 4 other than the cigarette insertion opening is sealed;

[0056] The side wall of the equal diameter cylinder 4 has an air inlet 9;

[0057] The constant diameter cylinder 4 and the inner diameter gradual change cylinder 5 are connected by airflow.

[0058] The heating elements are circumferential heating elements 3 arranged around the inner diameter gradual change cylinder and bottom heating elements 6 arranged at the bottom of the inner diameter gradual change cylinder.

[0059] The heating smoking device further comprises: a detachable baffle 1 located at the bottom of the inner diameter gradient tube, which is used to seal the bottom of the inner diameter gradient tube 5 to prevent tobacco particles from falling out during use. Of course, sealing can also be achieved by setting a bottom heating element 6 at the bottom of the inner diameter gradient tube 5.

[0060] The constant diameter cylinder 4 and the inner diameter gradual change cylinder 5 are fixedly connected or detachably connected.

[0061] The design of the cigarette insertion port allows the user to easily insert the cigarette or 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 truncated cone.

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

[0064] The cigarette also includes a cooling section 7 connected to the filter section 8 .

[0065] The cigarette also includes: a smoke-generating particle segment directly or indirectly connected to the filter segment 8, and the bottom of the smoke-generating particle segment is blocked by a heat-shrinkable blocking film.

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

[0067] The cigarette also includes: a cooling section 7 connected to the filter section 8. The cigarette may not be designed with a smoking section.

[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 smoking device is started, and the heating element heats the air in the inner diameter gradient tube 5 and radiates heat to the heat shrinkable sealing film at the bottom of the smoke-generating particle segment;

[0070] The heat-shrinkable sealing film ruptures after being heated, so that the smoke particles in the smoke particle section fall into the inner diameter gradient tube 5, and the smoke particles are heated to generate aerosols;

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

[0072] In the above working method, the conventional particle-type heated cigarette is still used, but the sealing film at the bottom of the cigarette is designed as a heat shrink film, which can be destroyed after heating. At this time, after the cigarette is inserted, the heat shrink film is destroyed under the heating of the heating element, and the smoke particles 2 fall from the cigarette and accumulate at the lower part of the inner diameter gradual tube 5.

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

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

[0075] At the same time, the smoke particles 2 are heated to generate aerosol;

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

[0077] In the above working method, the conventional particle-type heated cigarette is not used. The smoke particles 2 are added into the inner diameter gradient 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 to heat the smoke particles 2 by heating the air.

[0078] In the present application, the inner diameter of the equal diameter cylinder 4 remains unchanged, and the airflow performs high-speed rotation in this space. The cigarette insertion port is located on the upper surface of the equal diameter cylinder 4, and can be relatively sealed with the cigarette.

[0079] In the inner diameter gradient cylinder 5, the particles are thrown toward the side wall due to the centrifugal force and fall down due to the gravity.

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

[0081] Preferably, the air inlet 9 of the equal-diameter cylinder 4 is connected with an air inlet pipe. The extension direction of the air inlet pipe is the tangent direction of the equal-diameter cylinder 4.

[0082] The smoke particle circulation mechanism of this application is as follows:

[0083] During the suction process, the airflow enters from the air inlet 9, and forms a circulation inside the structure of the equal-diameter cylinder 4 and the inner diameter gradient cylinder 5, driving the smoke particles 2 to produce a spiral motion, similar to the principle of a cyclone separator, to achieve full contact between the smoke particles 2 and the airflow, thereby achieving effective extraction of smoke. However, due to the gravity of the smoke particles 2 themselves, the lift of the airflow is not enough to completely carry the smoke particles 2 out of the smoking device. This design ensures that the smoke particles 2 are picked up again by the airflow after falling in the smoking device, forming a reciprocating motion. During the suction process, the movement of the smoke particles 2 in the heating zone can maximize the release of the smoke generated in the heating state, thereby improving the utilization efficiency of tobacco. In the heating state, the smoke particles 2 remain stationary in the heating zone, and this is the smoke generation stage.

[0084] Preferably, the diameter of the cigarette insertion port is adapted to common granular heated cigarettes. 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 arranged at the lower part of the smoking device, which is convenient for cleaning and maintenance, and effectively prevents the smoke particles 2 from falling.

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

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

[0088] There are two heating methods for this application:

[0089] Circumferential heating element: A circumferential heating element 3 is provided inside the heating device, which adopts resistance heating 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 flow heating: A bottom heating element 6 is provided in front of the lower baffle of the smoking device, and its heating type is resistance heating. During the smoking process, the gas flows through the heating plate and is fully heated and in full contact with the particles, thereby heating the tobacco material.

[0091] Particle distribution: When the cigarette is inserted, tobacco particles will randomly fall into the heating zone, that is, the inner diameter gradient cylinder.

[0092] Suction phase:

[0093] When the user starts to smoke, the lift force generated by the main airflow causes the particles to move in a spiral motion in the heating area. Due to the gravity of the particles, the lift force is not enough to completely carry the particles out of the smoking device. After falling, the particles are picked up again by the airflow, forming a circular motion.

[0094] The above examples are only used to further illustrate the technical content of the present invention, so that readers can understand it more easily, but they do not mean that the implementation of the present invention is limited to this. Any technical extension or re-creation made according to the present invention is protected by the present invention. The protection scope of the present invention shall be subject to the claims.
