Description

Technical Field

[0001] This patent relates to the field of heated cigarette devices, specifically to a playful heated cigarette device and a playful heated cigarette system. Background Technology

[0002] Heated cigarettes, as a novel tobacco product, deliver nicotine and flavor compounds to users through heating rather than combustion, and have gained widespread acceptance and application in the market in recent years. The core function of the heated cigarette device used in conjunction with it is to provide precise and controllable heat energy to the inserted heated cigarette, allowing the aerosol-forming matrix in the heated cigarette to release inhalable aerosols at a suitable temperature, while simultaneously preventing actual combustion of the tobacco, thereby significantly reducing the harmful components produced by high-temperature decomposition.

[0003] Currently, mainstream heated cigarette devices on the market typically consist of a casing, a power supply unit, a control circuit, a heating element, and a heating chamber to hold the heated cigarette. Their basic operating procedure is roughly as follows: The user inserts the heated cigarette into the heating chamber and activates the heating program by pressing a button or using a sensor. The heating element then powers on and heats the cigarette. After a preheating period of several tens of seconds, the heated cigarette reaches a suitable operating temperature, and the user can then smoke it. After smoking, the user removes the heated cigarette from the heating chamber, and the device enters standby or cooling mode.

[0004] A common technical problem in existing heated cigarette devices is that the heated cigarette typically remains stationary within the heating chamber. Whether a needle-type heating element penetrates the cigarette from the inside, a cylindrical heating element surrounds the cigarette from the outside, or electromagnetic induction heating is used to heat a sensor, the relative position between the heated cigarette and the heating element remains constant throughout the heating and inhalation process. This "static heating" mode leads to a series of interconnected drawbacks.

[0005] First, ensuring uniform heating is difficult. For non-contact heating methods, such as electromagnetic induction heating or infrared radiation heating, the heating element or heat source is often concentrated in a specific location or area of ​​the heating chamber. A stationary heated cigarette will receive stronger and more concentrated heat radiation or conduction on the side closer to the heat source, while the side away from the heat source will receive relatively weaker heating. This uneven heating results in an uneven temperature distribution within the heated cigarette; some areas may be too hot, potentially producing a burnt taste or releasing undesirable components, while other areas may be too cold, resulting in insufficient aerosol release and affecting the consistency of the smoking experience.

[0006] For contact-type needle heating, although the heating needle is directly inserted into the cigarette, the heat of the outer part of the cigarette mainly relies on heat conduction from the center outward. There is also a radial temperature gradient, and the heat dissipation conditions may vary in different circumferential directions of the cigarette.

[0007] Secondly, the cigarette stick and the heating element are prone to sticking together. Due to uneven heating, the smoking agent, flavoring, and tobacco matrix in the heated cigarette, which are close to the heat source or in areas with excessively high temperatures, are prone to over-reaction, charring, or even carbonization, producing viscous tar-like residue.

[0008] These residues act like adhesive, bonding the outer surface of the heated cigarette to the inner wall of the heating chamber, or the inner surface of the heated cigarette to the needle heating element. This adhesion becomes particularly pronounced after smoking, often requiring considerable force to pull the cigarette out of the heating device.

[0009] Furthermore, the user experience is negatively impacted. The difficulty in removing the cigarette not only increases the user's operational challenge but can also cause the cigarette tube to break, tobacco to scatter, or even the cigarette to break off inside the heating chamber, requiring tools for removal. This severely affects the smoothness and enjoyment of smoking. Simultaneously, tar and soot residue remaining on the heating chamber or heating element are difficult to clean. Long-term accumulation reduces heating efficiency, produces odors, and increases the frequency and difficulty of cleaning and maintenance.

[0010] To address the aforementioned issues, existing technologies have proposed designs that improve heating uniformity or assist in smoke extraction by driving the heating chamber to rotate. For example, one solution uses a micro-motor as a power source, with button control to rotate the motor and drive the heating chamber. However, this electric rotation solution reveals new problems in practical applications: the motor's rotation generates perceptible noise, disrupting the quietness of the heating and suction process; button operation suffers from response delays and lacks directness; furthermore, the motor and its drive circuitry increase product cost, power consumption, and structural complexity, reducing overall reliability; and this program-controlled operation mode lacks direct interaction between the user and the product, failing to provide additional user enjoyment, its functional purpose primarily limited to solving technical problems.

[0011] Therefore, how to design a heated cigarette appliance that can effectively solve the problems of uneven heating and cigarette sticking, while also improving the user experience and product appeal, remains a technical challenge that needs to be addressed by those skilled in the art. Summary of the Invention

[0012] This patent aims to solve the technical problems of existing heated cigarette devices during use, such as uneven heating, cigarette sticking and difficulty in removal, and lack of interactive experience due to the inability of the heating chamber or heated cigarette to rotate. This patent provides the following technical solutions: In a first aspect, a playable heated cigarette device is provided, comprising: a device body; a toggle mechanism; and a heating mechanism; the toggle mechanism is disposed inside the device body and partially exposed on the outer surface of the device body, the heating mechanism is disposed entirely inside the device body, the rotation of the toggle mechanism can drive the heating mechanism to rotate, and the transmission ratio between the toggle mechanism and the heating mechanism is 1:1 to 12:1.

[0013] Furthermore, the transmission method between the actuating mechanism and the heating mechanism is one of gear transmission, chain transmission, or belt transmission.

[0014] Furthermore, the actuation mechanism and heating mechanism are gear-driven, and the play-type heated cigarette device also includes a transmission mechanism, which has a multi-stage transmission pair formed by a single gear or multiple gears.

[0015] Furthermore, the actuating mechanism and the heating mechanism form a parallel shaft gear structure, so that after the actuating mechanism is turned by hand, the actuating mechanism drives the heating mechanism to rotate through gear transmission. The playful heated cigarette device also includes a transmission mechanism, which is set between the actuating mechanism and the heating mechanism and is used to transmit the force of the actuating mechanism to the heating mechanism. The actuating mechanism, the transmission mechanism and the heating mechanism form a parallel shaft gear structure.

[0016] Furthermore, the actuating mechanism has a first gear and the heating mechanism has a second gear, with the first and second gears meshing externally; or the actuating mechanism has a first gear and the heating mechanism has a second gear, with the first gear meshing externally with the transmission mechanism, and the transmission mechanism meshing externally with the second gear; the first gear is the driving gear and the second gear is the driven gear.

[0017] Furthermore, the tooth surface shape of the first gear, the second gear, and the transmission mechanism is one of straight teeth, helical teeth, or herringbone teeth.

[0018] Furthermore, the actuating mechanism also includes an actuating component, which is connected to the first gear and disposed below the first gear; the actuating component is an integrally formed structure or an assembled structure; if the actuating component is an assembled structure, the actuating component includes an actuating bearing and a dial wheel, the dial wheel being disposed below the first gear, and the actuating bearing being disposed below the dial wheel.

[0019] Furthermore, the axle of the dial is one of a cylinder, triangular prism, cuboid, pentagonal prism, hexagonal prism, or octagonal prism; the outer diameter of the dial's circumscribed circle is 7~10mm, 10~13mm, or 13~16mm; the height of the dial's axle is 7~13mm, 13~19mm, or 19~25mm; the outer diameter of the actuating bearing is less than 15mm; the height of the actuating bearing is less than 4mm; and the frictional torque of the actuating bearing is less than 0.5N·m.

[0020] Furthermore, the heating mechanism also has a heating chamber, which is located inside the device body, and the second gear is located on the outer wall of the heating chamber or on the extension line of the outer wall; the heating method of the play-type heated cigarette device can be contact heating or non-contact heating; contact heating includes needle heating; non-contact heating includes one or more of electromagnetic induction heating, infrared radiation heating or hot air heating.

[0021] Secondly, a playable heated cigarette system is provided, including heated cigarette and the aforementioned playable heated cigarette device.

[0022] This patent has the following beneficial effects: 1. A playable heated cigarette device and a playable heated cigarette system are provided. The playable heated cigarette device in the playable heated cigarette system includes a device body, a tossing mechanism, a heating mechanism, and a transmission mechanism. The transmission mechanism is located between the tossing mechanism and the heating mechanism and is used to transmit the force of the tossing mechanism to the heating mechanism. The tossing mechanism, the transmission mechanism, and the heating mechanism form a parallel shaft gear structure. The transmission ratio between the tossing mechanism and the heating mechanism is 1:1 to 12:1, which allows the heated cigarette to be manually played with during the heating process to ensure uniform heating, thereby solving the problems of uneven heating and cigarette sticking, and improving the user experience and product fun.

[0023] 2. In this patent, a purely mechanical gear transmission structure enables the user to manually drive the heated cigarette to rotate within the heating chamber, significantly improving the uniformity of heating. Specifically, the user only needs to turn the first gear exposed on the outer surface of the device. Its rotational motion is then transmitted via a transmission mechanism, reducing speed and increasing torque, to the second gear connected to the heating chamber, thereby causing the entire heating chamber and the heated cigarette within it to rotate synchronously. During the heating process, especially in non-contact heating, the rotating heated cigarette allows each part of its circumference to sequentially pass through the heat source or the area with the strongest heat radiation. This is equivalent to dynamically and cyclically heating the entire outer surface of the cigarette, effectively eliminating hot and cold spots caused by a fixed heat source. This results in a more uniform temperature distribution within the heated cigarette and a more complete and consistent release of aerosols, ensuring a stable and mellow taste with every puff. It avoids burnt flavors or harmful substances caused by localized overheating, and also prevents waste caused by insufficient localized heating. This uniform heating effect is crucial for improving the overall smoking quality of heated cigarettes.

[0024] 3. This patent effectively prevents or reduces the adhesion problem between heated cigarettes and the heating element, making it easier and less strenuous to remove the cigarette after smoking. In contact heating methods such as needle heating, since the cigarette rotates with the heating chamber, the contact point between the inner surface of the hole and the heating needle is no longer fixed. The slow rotation of the cigarette creates a dynamic, relative motion relationship between the heating needle and the inner wall of the cigarette, which effectively breaks down or inhibits the continuous accumulation and solidification of local tar residues. Even if a small amount of tar is still generated, the rotation will distribute it more dispersedly and thinly, rather than forming a strong adhesion point in a single location. Therefore, when the user needs to remove the cigarette after smoking, the required pulling force is significantly reduced, and the cigarette can easily slide off the heating needle, greatly improving the user experience and avoiding cigarette breakage or tobacco falling off due to forced removal. For non-contact methods such as electromagnetic heating, uniform heating reduces local over-charring, which also reduces the amount of sticky residue generated at the source, keeping both the inside of the heating chamber and the surface of the cigarette relatively clean.

[0025] 4. This patent creatively integrates a playful element into the design of a heated cigarette appliance, significantly enhancing the product's fun and user interaction experience. This is thanks to the ingenious use of a one-way bearing in the actuation mechanism. When the user moves the first gear in one direction, the one-way bearing is locked, reliably transmitting torque to the transmission mechanism and heating chamber, driving their rotation and achieving uniform heating and anti-sticking functions. When the user quickly moves the first gear in the opposite direction, the one-way bearing is overrunning, the transmission path is cut off, and the first gear will smoothly and continuously spin freely due to the low-friction bearing on its shaft, similar to the playful effect of a fidget spinner or a lighter dial. This feature allows users to freely reverse the first gear for play even when heating is not activated or during the heating waiting process, obtaining the pleasant tactile and auditory feedback from the mechanical rotation. This design transforms the tedious waiting time for traditional heating devices into a fun and interactive process, satisfying users' potential playful needs. It makes the product more than just a functional electronic cigarette device; it's an exquisite toy with mechanical beauty and entertainment attributes, greatly enhancing the product's market appeal and user stickiness.

[0026] 5. This patent employs a purely mechanical transmission structure, eliminating the need for motors, complex drive circuits, and program control. This results in multiple advantages, including structural reliability, controllable cost, noiselessness, and zero delay. The gear transmission pair is compact, highly efficient, and has an extremely low failure rate. Furthermore, it does not require battery power to drive rotation, which is particularly important for portable heating devices that rely on battery power. Compared to electric rotation solutions, the manual mechanical structure of this invention operates silently, ensuring a quiet environment for the user during suction. Simultaneously, the user's operation and the rotation of the heating chamber are directly and instantly mechanically coupled, with no electronic response delay, providing an extremely direct and pure user experience. Moreover, components such as gears and the housing can be made of high-strength, wear-resistant, and self-lubricating engineering plastics, which are not only cost-effective but also ensure long-term stability and durability.

[0027] 6. In this patent, the invention achieves a balance between effortless operation and a good tactile feel through a reasonable transmission ratio design and component selection. The transmission ratio between the actuating mechanism and the heating mechanism is set within the range of 1:1 to 12:1, a carefully considered design. The higher transmission ratio acts as a speed reducer and torque increaser, allowing the user to easily actuate the first gear with minimal force. The heating chamber achieves a smooth, slow, yet sufficiently powerful rotation, ensuring the stability of the cigarette's rotation and uniform heating. Simultaneously, with the low-friction bearing, the first gear can maintain rotation for a longer period during reverse free spin; this free spin characteristic is key to achieving a superior tactile feel. The dimensions of the first gear are also ergonomically optimized, making it ideal for single-finger operation using the thumb or forefinger, resulting in natural and comfortable operation.

[0035] 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.

[0036] A playable heated cigarette device includes a generally rectangular body 100. The outer surface of the body 100 is covered with a shell, which is typically made of metal, plastic, or a combination of both, to protect the internal components and provide a good grip.

[0037] Inside the appliance body 100, cavities are formed for accommodating and installing various functional components. A cigarette insert 120 is provided on one end face of the appliance body 100, and the cigarette insert 120 communicates with an axially extending accommodating space inside the play-type heated cigarette appliance. On one side of the appliance body 100, a sliding window 110 is provided, allowing some components inside the appliance to be partially exposed.

[0038] The core of this invention is that the playable heated cigarette device includes a toggle mechanism 200, a heating mechanism 300 and a transmission mechanism 400 disposed inside the device body 100. The rotation of the toggle mechanism 200 can drive the heating mechanism 300 to rotate.

[0039] The transmission method between the actuating mechanism 200 and the heating mechanism 300 is one of gear transmission, chain transmission, or belt transmission. In one embodiment, the actuating mechanism 200 and the heating mechanism 300 are connected by belt transmission, that is, an annular belt is fitted on the outer surface of the actuating mechanism 200 and the heating mechanism 300, and the heating mechanism 300 is rotated by manually rotating the actuating mechanism 200. In another embodiment, a chain can also be fitted between the actuating mechanism 200 and the heating mechanism 300 for chain transmission.

[0040] In this embodiment, the transmission method between the actuating mechanism 200 and the heating mechanism 300 is preferably gear transmission. The actuating mechanism 200, the transmission mechanism 400, and the heating mechanism 300 together form a parallel shaft gear structure, that is, their rotation axes are parallel to each other. This layout is beneficial for achieving a compact internal space design.

[0041] Specifically, the actuating mechanism 200 mainly includes a first gear 220 and an actuating assembly. In this embodiment, the actuating assembly is an assembled structure, which includes a dial 230 and an actuating bearing 210. The dial 230 is located below the first gear 220, and the actuating bearing 210 is located below the dial 230.

[0042] The first gear 220 is a wheel-shaped component with external teeth. The tooth surface shape can be one of spur teeth, helical teeth, or herringbone teeth, among which spur gears are preferred due to their simple processing and low cost.

[0043] The rotating shaft of the dial 230 can be designed in various shapes such as cylinder, triangular prism, cuboid, pentagonal prism, hexagonal prism or octagonal prism to adapt to different assembly and torque transmission requirements.

[0044] A portion of the dial 230 is exposed to the outside through a toggle window 110 on the side of the appliance body 100, forming an operating interface that the user can directly touch and toggle with their fingers. To increase friction, the surface of the exposed portion of the dial 230 may be provided with anti-slip texture.

[0045] The height of the dial 230 is preferably set between 8 and 25 mm, and the outer diameter of the dial 230 is preferably set between 8 and 15 mm. This size design is ergonomic and makes it easy for users to perform easy and precise dialing operations with their thumb or index finger.

[0046] The actuating bearing 210 is located below the dial wheel 230, specifically between the shaft of the dial wheel 230 and the internal support of the appliance body 100. The dial wheel 230 is located between the first gear 220 and the actuating bearing 210. The actuating bearing 210 is a key component, and a one-way bearing is preferred.

[0047] A one-way bearing has the characteristic of being able to rotate freely in one direction of rotation, while locking and transmitting torque in the opposite direction. To achieve a good feel and smooth transmission, the outer diameter of the actuating bearing 210 is preferably less than 15 mm, the height is preferably less than 4 mm, and its frictional torque is preferably less than 0.5 N·m. The low frictional torque ensures that the first gear 220 can idle for a long period with low resistance when rotated in the opposite direction.

[0048] The heating mechanism 300 is used to accommodate and heat the heated cigarette inserted therein. The heating mechanism 300 mainly includes a heating chamber 310 and a second gear 320.

[0049] The heating chamber 310 is a generally cylindrical hollow component. The internal space of the heating chamber 310 is connected to the cigarette insertion port 120 of the device body 100, and is used to receive and hold heated cigarettes. The heating chamber 310 can be made of materials that are resistant to high temperatures, have good thermal conductivity, or have specific electromagnetic properties, depending on the heating method used.

[0050] The second gear 320 is fixedly mounted on the outer wall of the heating chamber 310. In a preferred embodiment, the second gear 320 can be integrally formed with the heating chamber 310, or firmly connected to it by means of interference fit, bonding, welding, etc. The tooth surface shape of the second gear 320 matches that of the first gear 220, and can also be spur, helical, or herringbone. As the final driven gear in the entire transmission chain, the diameter of the second gear 320 is usually larger than that of the first gear 220 to achieve the purpose of speed reduction and torque increase.

[0051] A transmission mechanism 400 is disposed between the actuating mechanism 200 and the heating mechanism 300, and is used to transmit the force applied on the actuating mechanism 200 to the heating mechanism 300. In this invention, although the transmission mechanism 400 is an optional component, its presence provides greater design flexibility.

[0052] The transmission mechanism 400 can be a single third gear 410, or it can be a multi-stage transmission pair composed of multiple gears.

[0053] In the simplest and preferred embodiment, the transmission mechanism 400 includes only one third gear 410. The third gear 410 meshes externally with the first gear 220 of the actuation mechanism 200 and the second gear 320 of the heating mechanism 300. In this way, the first gear 220, the third gear 410 and the second gear 320 mesh sequentially to form a single-stage reduction gear system.

[0054] The first gear 220 serves as the driving gear, and the second gear 320 serves as the driven gear. The transmission ratio of the entire transmission chain (i.e., the ratio of the rotational speeds of the first gear 220 and the second gear 320) is set between 1:1 and 12:1.

[0055] For example, when the transmission ratio is 10:1, the user will turn the first gear 220 10 times for the second gear 320 and the heating chamber 310 connected to it to rotate 1 time. This large transmission ratio design makes the rotation of the heating chamber 310 very smooth, and at the same time, the user will feel very little effort when operating the first gear 220.

[0056] A playable heated cigarette system is also provided, which includes a playable heated cigarette device and heated cigarette.

[0057] The specific implementation of the present invention will be described in detail below, taking into account two different heating methods.

[0058] Please refer to Figure 1 In this embodiment, the play-type heated cigarette device employs non-contact electromagnetic induction heating technology. Therefore, an electromagnetic induction heating mechanism 300 is also provided inside the device body 100. The electromagnetic induction heating mechanism 300 mainly includes an electromagnetic coil and a sensor. The heating cavity 310 itself or a separate component inside it can serve as the sensor.

[0059] In this embodiment, the heating cavity 310 is made of a conductive material that can respond to alternating magnetic fields, or a sensor is embedded in the inner wall of the heating cavity 310. An electromagnetic coil is arranged around the periphery of the heating cavity 310, and preferably, the electromagnetic coil is located in the middle section of the heating cavity 310. When a high-frequency alternating current passes through the electromagnetic coil, a high-frequency alternating magnetic field is generated around the coil. This magnetic field penetrates the wall of the heating cavity 310, generating eddy currents inside the conductive heating cavity 310, thereby causing the heating cavity 310 to heat up rapidly, and subsequently heating the heated cigarette inserted therein through thermal radiation and thermal conduction.

[0060] In this embodiment, the second gear 320 is disposed at the end of the outer wall of the heating cavity 310, for example, near the open or closed end of the heating cavity 310. This arrangement can avoid spatial interference between the second gear 320 and the electromagnetic coil located in the middle section of the heating cavity 310, making the structure of the entire heating mechanism 300 more compact.

[0061] The heating chamber 310, the electromagnetic coil, and the entire heating unit are concentric, meaning they share the same central axis. The heated cigarette entering the heating chamber 310 is also located on this axis, ensuring that the heated cigarette is evenly surrounded by the heat source.

[0062] The assembly process of the tactile heated cigarette device is roughly as follows: First, the actuating bearing 210 is installed on the pre-set bearing seat inside the device body 100. Then, the rotating shaft of the first gear 220 is inserted into the top rotating shaft of the dial wheel 230, and the bottom rotating shaft of the dial wheel 230 is inserted into the inner ring of the actuating bearing 210, with the actuating part of the dial wheel 230 aligned with the actuating window 110 on the side of the device body 100. Next, the heating chamber 310, together with the second gear 320 on its outer wall, is rotatably installed inside the device body 100 via the support bearings at both ends, ensuring that the axis of the heating chamber 310 is parallel to the axis of the first gear 220.

[0063] Then, the third gear 410 is rotatably mounted on the corresponding position of the appliance body 100 via the central shaft of the heating cavity 310, so that the third gear 410 meshes correctly with the first gear 220 and the second gear 320 respectively. Next, the electromagnetic coil is sleeved on the outside of the middle section of the heating cavity 310 and fixed. Finally, the outer shell of the appliance body 100 is closed, allowing part of the actuating portion of the dial 230 to protrude through the actuation window 110.

[0064] The working principle of this playful heated cigarette device is as follows: When the user needs to smoke a heated cigarette, first insert a heated cigarette into the heating chamber 310 through the cigarette insert 120. Then, the heating program is started, the electromagnetic coil starts working, and the heating chamber 310 heats up rapidly.

[0065] During the heating process, the user can use their finger to flick the dial 230 exposed at the flicking window 110 in a first direction (preferably clockwise). At this time, due to the one-way locking characteristic of the flicking bearing 210, the torque generated by the first gear 220 connected to the dial 230 is transmitted through the teeth of the first gear 220 to the third gear 410 meshing with the first gear 220. The third gear 410 then rotates and further transmits the torque to the second gear 320. The second gear 320 drives the heating chamber 310 and the heated cigarette held by the heating chamber 310 to rotate synchronously and slowly.

[0066] Since the heating chamber 310 is heated as a whole under the surrounding electromagnetic coil, every part of the circumference of the heating chamber 310 can receive heat radiation from the heating chamber 310 evenly during the rotation of the heated cigarette, thus achieving uniform heating of the entire cigarette.

[0067] The user can continuously or intermittently rotate the first gear 220 to keep the heated cigarette rotating during smoking. When the user finishes smoking and stops heating to remove the cigarette, the cigarette is almost completely free of adhesion to the inner wall of the heating chamber 310 because the cigarette is heated evenly during the heating process and there is no localized over-charring.

[0068] Please refer to Figure 2In another embodiment, the playful heated cigarette device employs a contact-type needle heating technology. The core of the heating mechanism 300 consists of a heating chamber 310 and a slender heating needle 330. The heating needle 330 is made of a metallic resistive material, and its base is fixed to the bottom of the device body 100 and electrically connected to a control circuit and power supply.

[0069] The heating needle 330 extends upward along the central axis of the heating cavity 310. When the heated cigarette is inserted into the heating cavity 310, the heating needle 330 penetrates and pierces the center of the heated cigarette. The heating cavity 310 itself mainly serves to accommodate and hold the cigarette, and the inner diameter of the heating cavity 310 matches the outer diameter of the heated cigarette.

[0070] Similar to Embodiment 1, this embodiment also includes a toggle mechanism 200, a heating mechanism 300, and a transmission mechanism 400. The toggle mechanism 200 also includes a first gear 220, a toggle wheel 230, and a toggle bearing 210 below the first gear 220. The heating mechanism 300 includes a heating chamber 310 and a second gear 320 fixed to the outer wall of the heating chamber 310.

[0071] The transmission mechanism 400 is also a separate third gear 410, which meshes with the first gear 220 and the second gear 320 respectively. In this embodiment, the gear teeth are also straight gears, i.e., spur gears. The layout, transmission ratio range, and assembly process of the entire transmission mechanism 400 are basically the same as in Embodiment 1, the difference being that the heating chamber 310 does not have an electromagnetic coil inside, but instead has a heating needle 330 located at its center.

[0072] The working principle of this playful heated cigarette device is as follows: The user inserts the heated cigarette into the heating chamber 310, and the heating needle 330 is then inserted into the inside of the cigarette. The heating program is activated, and the heating needle 330 is energized and rapidly heats up.

[0073] During heating and inhalation, the user can turn the dial 230 in the first direction. Power is transmitted to the second gear 320 via the third gear 410, causing the entire heating chamber 310 to rotate. Since the heating chamber 310 holds the heated cigarette, the cigarette will rotate along with it.

[0074] Although the heating needle 330 itself is stationary, the rotation of the cigarette creates a continuous relative rotation between its inner surface and the heating needle 330. This relative movement effectively prevents tar-like residues generated on the inner wall of the cigarette due to localized high temperatures from accumulating and solidifying into strong adhesive points in a single location. Even if a small amount of tar is generated, the rotational motion will spread it evenly or break it down with the constantly changing contact surface, thus greatly reducing the adhesion between the cigarette and the heating needle 330.

[0075] When the user finishes smoking and stops heating, the heated cigarette can be easily removed from the heating needle 330 because adhesion is effectively suppressed. Simultaneously, since the cigarette can rotate, its circumferential position within the heating chamber 310 changes, which to some extent compensates for the potential problem of uneven circumferential temperature in needle-type heating.

[0076] In both of the above embodiments, when the user quickly moves the dial 230 in a second direction opposite to the first direction (preferably counterclockwise), the one-way bearing is in an overrunning state, meaning its inner and outer rings can rotate freely relative to each other. At this time, the rotational torque of the first gear 220 will not be transmitted to the third gear 410 and the heating chamber 310.

[0077] The first gear 220, under the action of the extremely low-friction actuating bearing 210 on its shaft, will continue to spin like a miniature flywheel, emitting a slight mechanical sound, and will continue for several seconds or even longer before gradually stopping. Users can repeatedly perform this reverse tossing operation when the heating program is not started, or during the intervals of waiting for heating, and enjoy the fun it brings, similar to playing with a fidget spinner or a lighter dial.

[0078] Next, the playable heated cigarette system provided by the present invention will be described. The system includes the playable heated cigarette device described in any of the above embodiments, and a heated cigarette specifically used in conjunction with the device. The heated cigarette has a diameter matching the inner diameter of the heating chamber 310, and the heated cigarette contains an aerosol-forming matrix inside.

[0079] Once the heated cigarette is inserted into the heating chamber 310, the user can achieve uniform heating and prevent sticking by turning the dial 230 in the forward direction; turning the dial 230 in the reverse direction provides a more playful experience. This interactive heated cigarette system integrates functional operation with entertaining play, bringing users a completely new experience in using heated cigarettes.

[0080] In summary, this invention, through a sophisticated purely mechanical manual gear transmission mechanism 400 and its meticulous design of transmission ratio, bearing characteristics and gear size, not only achieves the core functions of uniform heating and anti-sticking removal of heated cigarettes, but also creatively incorporates a reverse rotation play function, and achieves the comprehensive advantages of noiseless, zero-delay, low cost and high reliability.

[0081] Those skilled in the art should understand that any modifications, equivalent substitutions, or improvements made to the specific tooth shape, size, material, transmission ratio, or heating method of the first gear 220, the third gear 410, and the second gear 320 without departing from the concept of the present invention should be included within the scope of protection of the present invention.

[0082] This patent specification uses directional terms such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom" to describe various example structural parts and components of this patent. However, the use of these terms is merely for illustrative purposes and is based on the orientation of the examples shown in the accompanying drawings. Since the embodiments disclosed in this patent can be arranged in different orientations, these directional terms are for illustrative purposes only and should not be considered as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or the same as the direction of gravity.

[0083] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this patent will not describe the various possible combinations separately.

[0084] Furthermore, various implementations of this patent can be combined in any way, and as long as they do not violate the spirit of this patent, they should also be regarded as the content disclosed in this patent.
