The content is sufficient for any person skilled in the art to understand the technical content of this patent and implement it accordingly. And according to the specification, claims and drawings disclosed in this specification, those skilled in the art can easily understand the related purposes and advantages of this patent.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this patent, "a plurality" means two or more unless otherwise specifically defined.

[0056] To make the purposes, technical solutions and advantages of this patent clearer, the following will further describe the implementation manners of this patent in detail with reference to the drawings.

[0057] In the first embodiment, specifically refer to Figures 1-6This patent is a non-smoking device that electrically heats non-burning cigarettes. The non-smoking device electrically heats non-burning cigarettes, which include: a filter section 1, a bituminous coal section 2, a heating element 35, a controller 36 and a power source (not marked in the figure). The filter section 1 is composed of cellulose acetate material, which is used to filter and / or cool the smoke; the bituminous coal section 2 is a solid aerosol generating matrix containing natural tobacco or reconstituted tobacco, specifically, including but not limited to tobacco shreds, flakes and other smoking substances; the controller 36 controls the power supply to transmit electrical energy to the heating element 35, so that the heating element 35 heats the bituminous coal section 2 close to the heating element 35, thereby generating smoke. The function of electrically heating non-burning cigarettes being formed in one piece and being able to be used independently without the need for heating in a smoking device is realized.

[0058] Specifically, the smokeless electric heating non-combustion cigarette includes a wrapper (not marked in the figure), which connects the filter section 1, the coal section 2, the controller 36, the heating element 35 and the power supply into a whole and forms a cigarette-shaped cylinder. Specifically, the wrapper is cigarette paper; the heating element 35 forms an integrated recyclable device group with the controller 36 and the power supply. Among them, the heating element 35 is a resistive heating element, which is in the shape of a needle-type or sheet-type internal heating structure. The resistive heating element protrudes from the recyclable device group and is inserted into the coal section 2. The resistive heating element is located in a parallel position to the axis of the cigarette, preferably between the axis and the periphery of the cigarette paper. When the resistive heating element is heated, the contact area can be increased, the utilization rate of coal can be increased, and the heating temperature can be reduced. The filter section 1, the coal section 2 and the main body of the recyclable device group are all cylindrical, and are connected into a whole by cigarette paper wrapping to form a cigarette-shaped cylinder. Its wrapping process can be used for traditional production line manufacturing, following standard process standards and operating procedures, improving the stability and consistency of cigarette products, and can also significantly improve production efficiency and reduce production costs. At the same time, in order to protect the environment and promote environmentally friendly behavior, consumers are advised to keep used cigarettes, and cigarette sales units should recycle used cigarettes, mainly recycling and reusing recyclable component groups.

[0059] Specifically, a puff indication area (not marked in the figure) is provided on the package, and the puff indication area includes temperature-sensitive materials. The first type of temperature-sensitive materials: when the cigarette starts to be heated and the outer surface of the bituminous coal segment 2 reaches the puff threshold temperature, the temperature-sensitive material changes color to indicate to the consumer that puffing has started. When the cigarette stops being heated, the temperature of the outer surface of the bituminous coal segment 2 drops, and the temperature-sensitive material returns to its original color to indicate to the consumer that puffing has ended. The second type of temperature-sensitive materials: when the cigarette starts to be heated and the outer surface of the bituminous coal segment 2 reaches the puff threshold temperature, the temperature-sensitive material changes color to indicate to the consumer that puffing has started. When the cigarette stops being heated, the temperature of the outer surface of the bituminous coal segment 2 drops, but the temperature-sensitive material still maintains the color of the outer surface of the bituminous coal segment 2 when it reaches the puff threshold temperature, and cannot return to its original color. It can be used to indicate to consumers that the cigarette has been puffed, making it easier for consumers to retain and identify cigarettes, playing an environmental protection role.

[0060] Specifically, the power supply section 4 includes a power supply and a protection circuit 47. The power supply includes an energy storage element 46, and the energy storage element 46 includes, but is not limited to, a battery and / or a capacitor. The total power of the energy storage element 46 is less than or equal to 80 mWh, 80 - 120 mWh, 120 - 160 mWh, 160 - 240 mWh, 240 - 320 mWh, 320 - 360 mWh, 360 - 380 mWh, or 380 - 400 mWh; the total weight of the energy storage element 46 is less than or equal to 0.8 g, 0.8 - 1.2 g, 1.2 - 1.6 g, 1.6 - 2.0 g, 2.0 - 2.4 g, 2.4 - 2.8 g, 2.8 - 3.2 g, 3.2 - 3.6 g, or 3.6 - 4.0 g; the total volume of the energy storage element 46 is less than or equal to 0.8 cm 3 、0.8 - 1.2 cm 3 、1.2 - 1.6 cm 3 、1.6 - 2.0 cm 3 、2.0 - 2.4 cm 3 、2.4 - 2.8 cm 3 、2.8 - 3.2 cm 3 、3.2 - 3.6 cm 3 or 3.6 - 4.0 cm 3 。The energy storage element 46 is small in volume and light in weight, and is suitable for being wrapped by cigarette paper.

[0061] Specifically, the recyclable device group includes a heating circuit section 3 and a power supply section 4; the heating circuit section 3 includes a heating element 35 and a controller 36, which is used to capture the temperature of bituminous coal and perform on-off control. In order to simplify the above-mentioned controller 36 as much as possible, since the high-temperature resistance characteristics of semiconductor materials are not applicable to this environment, the use of semiconductor components is minimized. Therefore, the controller 36 adopts an integrated design and a mechanical temperature acquisition and control method. Specifically, the controller 36 is a temperature sensor, the temperature sensor is a thermal breaker, the thermal breaker is a thermal expansion breaker, and the thermal expansion breaker includes an airbag structure and / or a bimetal structure.

[0062] Specifically, the temperature sensor 36 includes a housing 361, an airbag 362, an elastic arm 363, a first contact 364, a second contact 365, and a breaking element. The housing 361 is made of engineering plastic, metal, ceramic, or other materials with a specific heat capacity less than or equal to 2000 j / (kg·K); the airbag 362 is located inside the housing, and the airbag 362 is filled with gas, which is air or other non-flammable gas that can expand as the temperature rises; the airbag 362 is composed of elastic materials, and the elastic materials include PP, TEP, and TPR; the elastic arm 363 is a structure or material with elasticity, and the elastic structure or material includes springs and silica gel; the first contact 364 and the second contact 365 are made of conductor materials. Among them, the first contact 364 is connected to the battery output terminal, and the second contact 365 is connected to the heating element 35; a breaking element is provided between the circuits formed by the heating element 35, the controller 36, and the power supply. The breaking element is an insulating sheet 37, and the consumer can achieve the connection of the circuit by removing the insulating sheet 37.

[0063] Specifically, when the cigarette is not in use, the insulating sheet 37 has not been removed by the consumer, and the circuit formed by the heating element 35, the controller 36, and the power supply is in an open state. The energy storage element 46 cannot provide energy to the heating element 35, and the heating element 35 does not heat up; when the cigarette is in use, the insulating sheet 37 is removed by the consumer, and the circuit formed by the heating element 35, the controller 36, and the power supply is in a broken state, that is, the circuit between the first contact 364 and the second contact 365 is broken, and the temperature sensor 36 is in a closed state. The energy storage element 46 provides energy to the heating element 35 through protecting the controller 36, and the heating element 35 starts to heat the tobacco. The temperature of the tobacco rises and is transmitted to the airbag 362 through the housing 361. The gas in the airbag 362 expands when heated. When the gas expands to a certain threshold, the airbag 362 pushes the elastic arm 363 to a contracted state. At this time, the first contact 364 and the second contact 365 are disconnected, and the temperature sensor 36 is in an open state. The heating element 35 stops heating the tobacco, and the temperature of the tobacco drops; this drives the temperature of the gas in the airbag 362 to drop, causing the airbag 362 to contract, and the elastic arm 363 expands and presses the first contact 364, causing the first contact 364 and the second contact 365 to be broken again. This process repeats to form a constant temperature control, which is more beneficial for heating the tobacco. During this period, the consumer can smoke the cigarette. When the voltage of the energy storage element 46 drops to 2.5V, the protection circuit 47 cuts off the circuit formed by the heating element 35, the controller 36, and the power supply, and the usage process ends.

[0064] Specifically, the heating circuit section 3 further includes a heat insulation member (not marked in the figure) for isolating the heat transfer from the heating element 35 to the power supply section. The heat insulation member includes acetate fiber, and the temperature sensor 36 is arranged at one end of the heat insulation member close to the heating element 35.

[0065] Specifically, the wrapping method of the smokeless electric heated non-combustible cigarette is that the tobacco coal section 2 is connected to the heating circuit section 3 to form a composite section 61, the composite section 61 is connected to the power supply section 4 to form a composite section 62, and the composite section 62 is further connected to the filter section 1 to form a composite section 63, and the composite section 63 is the smokeless electric heated non-combustible cigarette.
