Description

Technical Field

[0001] This invention belongs to the field of novel heated tobacco products, specifically relating to an electric heated non-combustible cigarette without a smoke-emitting device. Background Technology

[0002] Most current heated tobacco products consist of a device and a cigarette, with a few also including a charging case. To use, first remove the cigarette from the storage box, place it in the device, and then activate the device to heat it. Once preheating is complete, the user can smoke normally. Used cigarettes can be discarded or placed in a temporary storage container.

[0003] Consumers using cigarettes need to carry more items, and the operation process is somewhat complicated. Furthermore, after multiple uses, the heated tobacco device easily accumulates tar and other residues, requiring cleaning and further complicating the process. Additionally, because cigarettes require separate devices, they cannot be shared like traditional cigarettes, significantly diminishing the social function that tobacco originally possessed.

The total power of the energy storage element in the cigarette is controlled within 400mWh, the total weight is controlled within 4g, and the total volume is controlled within 4cm. 3 The design should be lightweight and portable. Ideally, the total weight and volume of the energy storage element should be as small as possible, but the total capacity of the energy storage element needs to be 80mWh or more to meet the basic needs of smoking the entire cigarette. The higher the total capacity of the energy storage element, the longer it can provide power to the heating element, resulting in more volatile smoke-producing substances and providing consumers with greater satisfaction and a more comfortable smoking experience. At the same time, the cigarette should be lightweight and easy to carry, allowing it to be shared like traditional cigarettes, restoring the social aspect of tobacco. Furthermore, the rolling and packaging process can be applied to traditional production lines.

[0053] The detailed features and advantages of this patent are described below in the specific embodiments. The content is sufficient to enable any person skilled in the art to understand the technical content of this patent and implement it accordingly. Based on the specification, claims and drawings disclosed in this specification, a person skilled in the art can easily understand the related objectives and advantages of this patent.

[0054] It should be noted that in this specification, similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. It should also be understood that the term "and / or" as used herein refers to and includes any and all possible combinations of one or more associated listed items.

[0055] It should be understood that although the terms "first," "second," etc., may be used in this patent to describe various types of information, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this patent, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this patent, "a plurality of" means two or more, unless otherwise explicitly specified.

[0056] To make the objectives, technical solutions, and advantages of this patent clearer, the embodiments of this patent will be described in further detail below with reference to the accompanying drawings.

[0057] In the first embodiment, see specific reference. Figures 1-6 This patent describes a smokeless, electrically heated, non-combustible cigarette. The cigarette comprises: a filter section 1, a bituminous coal section 2, a heating element 35, a controller 36, and a power source (not shown in the figure). The filter section 1 is composed of cellulose acetate material and is used to filter and / or cool the smoke. The bituminous coal section 2 is a solid aerosol-generating matrix containing natural or reconstituted tobacco, specifically including but not limited to tobacco shreds, flakes, and other smoke-generating substances. The controller 36 controls the power source to supply electrical energy to the heating element 35, causing the heating element 35 to heat the bituminous coal section 2 near it, thereby generating smoke. This invention achieves the functionality of an integrally molded electrically heated, non-combustible cigarette that can be used independently without the need for a separate heating device.

[0058] Specifically, the smokeless electrically heated non-combustible cigarette includes a wrapping component (not shown in the figure). This wrapping component rolls and connects the filter section 1, the bituminous coal section 2, the controller 36, the heating element 35, and the power supply into a single, cigarette-shaped cylinder. Specifically, the wrapping component is cigarette paper; the heating element 35, controller 36, and power supply form a recyclable device assembly. The heating element 35 is a resistance heating element with a needle-like or plate-like internal heating structure. The resistance heating element protrudes from the recyclable device assembly and is inserted into the bituminous coal section 2. The resistance heating element is located parallel to the cigarette axis, preferably between the axis and the outer periphery of the cigarette paper. When the resistance heating element heats, it increases the contact area, increases the bituminous coal utilization rate, and lowers the heating temperature. The filter section 1, the bituminous coal section 2, and the main body of the recyclable device assembly are all cylindrical and are connected by a rolled-up cigarette paper to form a cigarette-shaped cylinder. Its rolling and packaging process can be used in traditional production lines, following standard process standards and operating procedures, improving the stability and consistency of cigarette products, and also significantly increasing production efficiency and reducing production costs. Meanwhile, to protect the environment and promote environmentally friendly behavior, consumers are advised to keep used cigarettes, and cigarette retailers should recycle used cigarettes, primarily focusing on the recycling and reuse of recyclable components.

[0059] Specifically, the package features a smoking indicator area (not shown in the diagram). This area includes temperature-sensitive materials. The first type of temperature-sensitive material changes color when the cigarette starts heating and the outer surface of the bituminous segment 2 reaches the smoking threshold temperature, indicating to the consumer that smoking has begun. When the cigarette stops heating, the temperature of the outer surface of the bituminous segment 2 decreases, and the temperature-sensitive material returns to its original color, indicating to the consumer that smoking has ended. The second type of temperature-sensitive material changes color when the cigarette starts heating and the outer surface of the bituminous segment 2 reaches the smoking threshold temperature, indicating to the consumer that smoking has begun. When the cigarette stops heating, the temperature of the outer surface of the bituminous segment 2 decreases, but the temperature-sensitive material retains the color it had when the outer surface of the bituminous segment 2 reached the smoking threshold temperature and cannot return to its original color. This allows the consumer to easily retain and identify the cigarette, thus contributing to environmental protection.

[0060] Specifically, power supply segment 4 includes a power supply and protection circuit 47. The power supply includes energy storage elements 46, which include, but are not limited to, batteries and / or capacitors. The total capacity of the energy storage elements 46 is less than or equal to 80mWh, 80-120mWh, 120-160mWh, 160-240mWh, 240-320mWh, 320-360mWh, 360-380mWh, or 380-400mWh; the total weight of the energy storage elements 46 is less than or equal to 0.8g, 0.8-1.2g, 1.2-1.6g, 1.6-2.0g, 2.0-2.4g, 2.4-2.8g, 2.8-3.2g, 3.2-3.6g, or 3.6-4.0g; and the total volume of the energy storage elements 46 is less than or equal to 0.8cm³. 3 0.8-1.2cm 3 1.2-1.6cm 3 1.6-2.0cm 3 2.0-2.4cm 3 2.4-2.8cm 3 2.8-3.2cm 3 3.2-3.6cm 3 Or 3.6-4.0cm 3 The energy storage element 46 is small in size and light in weight, making it suitable for rolling cigarette paper.

[0061] Specifically, the recyclable device segment group includes a heating circuit segment 3 and a power supply segment 4; the heating circuit segment 3 includes a heating element 35 and a controller 36, used to capture the temperature of the bituminous coal and perform switching control. To simplify the controller 36 as much as possible, since the high-temperature resistance of semiconductor materials is not suitable for this environment, the use of semiconductor components is minimized. Therefore, the controller 36 adopts an integrated design and uses a mechanical temperature acquisition and control method. Specifically, the controller 36 is a temperature sensor, which is a thermal circuit breaker, and the thermal circuit breaker is a thermal expansion circuit breaker, which includes an airbag structure and / or a bimetallic structure.

[0062] Specifically, the temperature sensor 36 includes a housing 361, an air bladder 362, an elastic arm 363, a first contact 364, a second contact 365, and a circuit breaker element. The housing 361 is made of engineering plastic, metal, ceramic, or other materials with a specific heat capacity of less than or equal to 2000 J / (kg·K). The air bladder 362 is located inside the housing and contains gas, which is air or other non-flammable gas that expands with increasing temperature. The air bladder 362 is composed of elastic materials, including PP, TEP, and TPR. The elastic arm 363 is an elastic structure or material, including springs and silicone. The first contact 364 and the second contact 365 are conductive materials. The first contact 364 is connected to the battery output terminal, and the second contact 365 is connected to the heating element 35. A circuit breaker element, an insulating sheet 37, is provided between the heating element 35, the controller 36, and the power supply. The consumer connects the circuit by removing the insulating sheet 37.

[0063] Specifically, when the cigarette is not in use, the insulating sheet 37 is not removed by the consumer, and the circuit formed by the heating element 35, the controller 36, and the power supply is open. The energy storage element 46 cannot provide energy to the heating element 35, and the heating element 35 does not heat. 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 open, i.e., the first contact 364 and the second contact 365 are disconnected. The temperature sensor 36 is closed, and the energy storage element 46 provides energy to the heating element 35 through the protection of the controller 36. The heating element 35 begins to heat the bituminous coal, and the temperature of the bituminous coal rises and is transferred to the air bladder 362 through the outer shell 361. The gas inside the air bladder 362 expands due to heat. 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 disconnect, the temperature sensor 36 is in the open state, the heating element 35 stops heating the bituminous coal, and the temperature of the bituminous coal drops. This causes the gas temperature inside the airbag 362 to drop, causing the airbag 362 to contract. The elastic arm 363 expands and squeezes the first contact 364, causing the first contact 364 and the second contact 365 to disconnect again. This process repeats to form a constant temperature control, which is more conducive to the heating of the bituminous coal. During this period, consumers can smoke cigarettes. When the voltage of the energy storage element 46 drops to 2.5V, the protection circuit 47 cuts off the circuit composed of the heating element 35, the controller 36, and the power supply, and the use process ends.

[0064] Specifically, the heating circuit segment 3 also includes a heat insulation component (not shown in the figure) for isolating the heat transfer from the heating element 35 to the power supply segment. The heat insulation component includes cellulose acetate, and the temperature sensor 36 is located at the end of the heat insulation component near the heating element 35.

[0065] Specifically, the packaging method of the smokeless electric heating non-combustible cigarette is as follows: the bituminous 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 then connected to the filter section 1 to form a composite section 63. The composite section 63 is the smokeless electric heating non-combustible cigarette.

[0066] Specifically, the heating circuit section 31 and the power supply section 42 are sealed together. The heating circuit section 31 of the cigarette paper is provided with air inlets 51a, 51b, 51c and 51d. The air inlets are perforated and the shape of the holes includes, but is not limited to, circles and squares. Air can enter through the air inlets 51a, 51b, 51c and 51d and pass through the bituminous coal section 21 and the filter section 11 in sequence before entering the consumer's mouth.

[0067] In another specific embodiment, reference can be made to Figure 7 The air intake path in Embodiment 1 is modified. The heating circuit section 32 and the power supply section 42 are sealed together. An air intake hole 52 is provided on the heating circuit section 32 of the cigarette paper. The air intake hole is cut in a slit manner, so that air can enter through the air intake hole 52 and pass through the bituminous coal section 22 and the filter section 12 in sequence before entering the consumer's mouth.

[0068] In another specific embodiment, reference can be made to Figure 8 , Figure 9 The air intake path in Embodiment 1 is modified. A sealed arrangement is adopted between the heating circuit section 33 and the power supply section 43, preventing air from flowing through the power supply section 43. Air intake holes 53a, 53b, 53c, and 53d are provided on the bituminous coal section 23 of the tobacco paper. The air intake holes are perforated, and the shapes of the holes include, but are not limited to, circles and squares. The bituminous coal section has a double-layer tobacco paper structure, including an outer layer of tobacco paper 55 and an inner layer of tobacco paper 56. A support member 57 is provided between the outer layer of tobacco paper 55 and the inner layer of tobacco paper 56, allowing air to enter through the air intake holes 53a, 53b, 53c, and 53d and flow along the gap 58 between the tobacco paper and the bituminous coal section 23 from the end closer to the filter section 13 (proximal end) to the end farther from the filter section 13 (distal end), entering the recovery device group. Then, it flows from the distal end to the proximal end and sequentially passes through the bituminous coal section 23 and the filter section 13 before entering the consumer's mouth.

[0069] In another specific embodiment, reference can be made to Figure 10aThe air intake path in Embodiment 1 is modified. The power supply section 44 has a double-layer cigarette paper structure, including an outer cigarette paper 155 and an inner cigarette paper 156. The power supply section 44 is disposed within the inner cigarette paper 156, which is centered and parallel to the outer cigarette paper 155, so that the power supply section 44 does not directly contact the air. There are multiple support members 157 between the outer cigarette paper 155 and the inner cigarette paper 156. The support members 157 are used to fix the power supply section 44. There are gaps 158 between the multiple support members 157, so that air can enter from the far end of the recyclable device group and pass through the recyclable device group and the bituminous coal section sequentially along the gaps 158. Figure 10a (not marked in the text) and filter section ( Figure 10a (Not labeled) enters the consumer's mouth.

[0070] In another specific embodiment, reference can be made to Figure 10b The air intake path in Embodiment 1 is modified.

The power supply section 45 is disposed inside the inner cigarette paper 256, with one side of the inner cigarette paper 256 abutting against the outer cigarette paper 255, so that the power supply section 45 does not directly contact the air. There are multiple support members 257 between the outer cigarette paper 255 and the inner cigarette paper 256. The support members 257 are used to fix the power supply section 45. There are gaps 258 between the multiple support members 257, allowing air to enter from the far end of the recyclable device group and pass sequentially through the recyclable device group and the bituminous coal section along the gaps 258.

The inner smoke paper 356 is a closed, but not limited to, regular shapes such as perfect circles; it can be an ellipse, a fan shape, or even a pleated, spiky shape formed by the stacking of the inner smoke paper 356, so that the power supply section 48 does not directly contact the air. There are no supporting members between the outer smoke paper 355 and the inner smoke paper 356; the power supply section 48 is only supported and fixed by the inner smoke paper 356. There are gaps 358 between the pleats and spiky shapes formed by the stacking of the inner smoke paper 356, allowing air to enter from the far end of the recyclable device group and pass sequentially through the recyclable device group and the bituminous coal section (…) along the gaps 358. Figure 10c (not marked in the text) and filter section ( Figure 10c (Not labeled) enters the consumer's mouth.

[0072] Therefore, it can be concluded that the smokeless, heated, non-combustible cigarette provided by this invention has the following advantages over the prior art:

[0073] 1. The smokeless, electrically heated, non-combustible cigarette of this patent is integrally molded, can be used independently, is simple to operate, easy to store, requires no cleaning, and does not require a special smoking accessory. The total power of the energy storage element 46 in the cigarette is controlled within 400mWh, the total weight is controlled within 4g, and the total volume is controlled within 4cm. 3 The design prioritizes portability, and ideally, the total weight and volume of the energy storage element 46 should be as small as possible. However, the total capacity of the energy storage element 46 needs to be 80mWh or higher to meet the basic requirements for smoking the entire cigarette. The higher the total capacity of the energy storage element 46, the longer it can provide power to the heating element 35, resulting in more volatile smoke-producing substances and providing consumers with greater satisfaction and a more comfortable smoking experience. Simultaneously, the cigarette's overall weight is relatively light, making it easy to carry. It can be shared like traditional cigarettes, restoring the social aspect of tobacco, and the rolling process can be applied to traditional production lines.

[0074] 2. The smoke-free electric heating non-combustible cigarette of this patent still uses electric heating to generate smoke. The heating temperature is lower than the combustion temperature of the tobacco medium, and constant temperature control can be performed.

[0075] 3. The smokeless electric heating non-combustible cigarette of this patent has a smoking indicator. The smoking indicator area includes a temperature-sensitive material, which can indicate to the consumer whether smoking has started, smoking has ended, and / or whether the cigarette has been smoked.
