[0034] In order to facilitate the understanding of the present invention, specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0035] Unless otherwise specified or defined, the "first, second..." used in this article is only used to distinguish names and does not represent a specific quantity or order.

[0036] Unless stated otherwise or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] It should be noted that, in this document, “fixed to” or “connected to” may mean directly fixing or connecting to an element, or indirectly fixing or connecting to an element.

[0038] It should be noted that the cigarette device can be loaded with smokeable materials for combustion to form smoke for inhalation, wherein the smokeable materials can be replaced according to personal smoking habits and can be various materials that can be inhaled, such as tobacco materials, etc., and there is no special limitation here.

[0039] An embodiment of the present invention provides a cigarette device, as shown in FIG. 1 to FIG. 10 , the cigarette device comprises a cigarette tube 1 , a first isolating member 2 and a cigarette holder 3 which are arranged in sequence.

[0040] The cigarette tube 1 is rolled to form a hollow interior containing space 11, which is used to accommodate inhalable materials such as tobacco materials. For ease of description, the inhalable materials will be replaced by tobacco materials, but this does not mean that the inhalable materials are limited to tobacco materials. Other materials that can be burned to form smoke for inhalation are also applicable. The tobacco materials can be filled manually or with the assistance of a filling tool, without any special restrictions. In addition, it should be noted that the cigarette tube 1 is made of a combustible material, such as cigarette paper made from hemp pulp or natural fibers such as wood pulp, and fillers such as calcium carbonate. It is usually white, but also available in other colors such as brown. It must not have any odor when burned and can be ignited and inhaled after being filled with tobacco materials. The cigarette tube 1 can originally be a rolled tubular structure with the containing space 11, or it can be originally unfolded and then folded or glued to form the containing space 11 when inhalation is required, without any special restrictions.

[0041] The cigarette holder 3 has a first guide channel 31; wherein, the original state of the cigarette holder 3 can be a rolled cigarette holder 3 with the first guide channel 31, or the original state of the cigarette holder 3 can be an unfolded state, and then rolled to form the cigarette holder 3 with the first guide channel 31 when smoking is needed, and there is no special limitation here.

[0042] The first isolating member 2 separates the cigarette holder 3 from the cigarette material, and the first isolating member 2 has a second flow guiding channel 21 connected to the first flow guiding channel 31 and the accommodating space 11 respectively.

[0043] The mouthpiece 3, first separator 2, and cigarette tube 1 can be assembled in a complete structural state when shipped from the factory, and when smoking is desired, tobacco materials can be filled into the receiving space 11 of the cigarette tube 1 and sealed. Alternatively, the mouthpiece 3, first separator 2, and cigarette tube 1 can be assembled in a complete structural state when shipped from the factory, and tobacco materials have already been filled into the receiving space 11 of the cigarette tube 1 and sealed. Alternatively, the mouthpiece 3, first separator 2, and cigarette tube 1 of the cigarette rolling device can be separated and unfolded when shipped from the factory, and when smoking is desired, the three can be folded and assembled, and tobacco materials can be filled into the receiving space 11 of the cigarette tube 1 and sealed. There is no particular limitation here.

[0044] Among them, by adding the first isolation member 2 between the cigarette holder 3 and the cigarette pipe 1, the first isolation member 2 can isolate the tobacco material and the cigarette holder 3. On the one hand, it can effectively isolate the heat generated by the combustion of the tobacco material in the cigarette pipe 1, effectively reduce the heat conduction to the cigarette holder 3, and effectively avoid burning the mouth. On the other hand, it can effectively avoid directly inhaling unburned tobacco material fragments during the process of smoking through the cigarette holder 3, and can make the tobacco material burn fully. The first isolation member 2 is provided with a second guide channel 21 that can connect the first guide channel 31 and the accommodating space 11 of the cigarette pipe 1, which can ensure that the smoke flows smoothly from the cigarette pipe 1 to the cigarette holder 3 for smoking, and the extended airflow channel can also control the airflow of the smoke, so that the smoke airflow flows evenly, effectively improving the smoking experience.

[0045] In some embodiments, as shown in Figures 1 and 8 , the mouthpiece 3 is provided with a rim 34 at one end near the cigarette tube 1. A receiving groove is formed within the rim 34, and the first spacer 2 is at least partially accommodated within the receiving groove. The cigarette tube 1 is fitted around at least a portion of the outer circumference of the mouthpiece 3. The rim 34 provided on the mouthpiece 3 limits and secures the position of the first spacer 2, facilitating quick assembly. The first spacer 2 may be partially accommodated within the receiving groove of the rim 34, or the entire first spacer 2 may be accommodated within the rim 34, with the end face of the first spacer 2 flush with the edge of the rim 34. The cigarette tube 1 fits around at least a portion of the outer circumference of the mouthpiece 3. Specifically, the cigarette tube 1 may fit around the entire outer circumference of the mouthpiece 3, or it may fit around a portion of the outer circumference of the mouthpiece 3. The tight fit between the two ensures that the cigarette tube 1 and the mouthpiece 3 are fixed to each other and smoothly transitions between them, effectively preventing smoke from escaping through the gap between the two.

[0046] In some embodiments, as shown in Figures 3, 6, and 8, the mouthpiece 3 includes a flexible folding body 32. The folding body 32 can be made of a paper material with a certain hardness, such as tipping paper, without particular limitation. The folding body 32 is formed into a multi-layered roll-shaped mouthpiece by rolling and / or folding. A space exists between at least two adjacent layers of the roll-shaped mouthpiece, and the space cooperates to form the first flow-guiding channel 31. The mouthpiece 3 can be shipped as a pre-folded and pre-shaped roll-shaped mouthpiece, ready for direct assembly when inhalation is desired. Alternatively, the mouthpiece 3 can be shipped in an unshaped, unfolded state, and when inhalation is desired, the roll-shaped mouthpiece is formed by folding. A space exists between at least two adjacent layers of the roll-shaped mouthpiece for airflow guidance, allowing smoke from the burning tobacco material in the cigarette tube 1 to smoothly pass through the space between at least two adjacent layers of the mouthpiece 3 and enter the mouth for inhalation. The multi-layer structure enhances structural strength and disperses smoke flow, thereby improving the smoking experience.

[0047] In some embodiments, as shown in Figures 3, 6, and 8, the roll-up body 32 includes a first roll-up body 321 and a second roll-up body 322 connected to the first roll-up body 321. After the roll-up body 32 is rolled and / or folded, the second roll-up body 322 surrounds the outer periphery of the roll-up loop of the first roll-up body 321 and partially protrudes beyond the roll-up loop of the first roll-up body 321. The portion of the second roll-up body 322 protruding beyond the roll-up loop of the first roll-up body 321 forms the surrounding edge 34. The first and second roll-up bodies 321 and 322 can be integrally formed or separately connected, preferably integrally formed. Through their shape design and folding in a specific direction, the roll-up loop of the second roll-up body 322, after folding, is positioned around the outer periphery of the roll-up loop of the first roll-up body 321 and at least partially protrudes beyond the outer periphery of the roll-up loop of the first roll-up body 321, thereby forming the surrounding edge 34 structure capable of securing the first spacer 2. Specifically in this embodiment, when the first folding body 321 and the second folding body 322 are in the unfolded state, the first folding body 321 and the second folding body 322 cooperate to form an L-shaped folding body. By setting the L-shaped folding body, the edge 34 structure can be quickly formed during the folding process, and assembly is more convenient.

[0048] In some embodiments, as shown in FIG8 , the longitudinal cross-section of the mouthpiece 3 presents a rolled structure with an M-shaped inner layer and a spiral outer layer. Pre-defined folds can be formed on the roll-folding body 32, allowing the mouthpiece 3 to be folded to form an M-shaped inner layer and a spiral outer layer. This structure provides a better airflow guidance effect and can enhance the smoking experience. Alternatively, in other embodiments, as shown in FIG9 , the longitudinal cross-section of the mouthpiece 3 presents a spiral rolled structure. This spiral rolled structure facilitates the rolling and folding operation and can also provide a better smoking experience.

[0049] In some embodiments, as shown in Figure 4, the second guide channel 21 includes a plurality of air flow holes opened by the first isolation member 2 along its own axial direction, wherein the plurality of air flow holes can ensure that the air flow path is unobstructed, thereby greatly enhancing the smoking experience; the first isolation member 2 is concave inward at one end close to the cigarette pipe 1 to form a groove 22 connected to the air flow hole, and the groove 22 extends outward in its own radial direction to form a radial air channel 23. The structural arrangement of the radial air channel 23 and the groove 22 can effectively prevent the tobacco material from blocking the air flow hole, thereby forming unobstructed side and top air flow channels.

[0050] In some embodiments, the first spacer 2 is a ceramic structure. Ceramic structures offer excellent thermal insulation and flame retardancy, are widely available, and are low-cost, effectively reducing costs. Of course, in other embodiments, the first spacer 2 can also be made of other thermal insulation and flame retardant materials, without particular limitation.

[0051] In some embodiments, the first spacer 2 is cylindrical, with its peripheral wall protruding outward to form a convex arc structure. The radial length of the first spacer 2 near the tobacco tube 1 is greater than its radial length near the mouthpiece 3. The convex arc shape of the peripheral wall of the first spacer 2 facilitates the gripping of the first spacer 2 within the tobacco tube 1, thereby simplifying and facilitating the assembly process. Furthermore, the radial length of the first spacer 2 near the tobacco tube 1 is greater than its radial length near the mouthpiece 3, allowing the airflow generated by the burning tobacco material to be better concentrated in the oral cavity at the mouthpiece 3, further enhancing the inhalation experience.

[0052] In some embodiments, as shown in FIG. 1 and FIG. 2 , the cigarette device as a whole is approximately in the shape of a conical tube, and the radial length of the cigarette holder 3 end is smaller than the radial length of the cigarette tube 1 end.

[0053] In some embodiments, as shown in Figures 2, 5, and 10, the cigarette device further includes a second separator 4 having adsorption properties and disposed between the cigarette holder 3 and the first separator 2. As shown in Figures 7 and 9, when the cigarette device further includes the second separator 4, its height can be significantly increased on the second folding body 322 of the folding body 32 to adjust the depth of the edge 34 of the folded cigarette holder 3. The second separator 4 can be completely accommodated within the edge 34, and at least part of the structure of the first separator 2 can also be accommodated within the edge 34. The second separator 4 can be flame-retardant, heat-resistant, and oil-absorbing cotton, capable of absorbing harmful substances and having flame-retardant and heat-resistant effects, further enhancing the smoking experience.

[0054] In some embodiments, a seasoning is placed in the second isolating member 4, and the seasoning contains a seasoning material. Specifically, a mounting hole 41 can be opened on the second isolating member 4, and the seasoning with the seasoning material is placed in the mounting hole 41, wherein the seasoning material can specifically be a tobacco popping bead or a flavor granule that can provide a seasoning material with different flavors, thereby providing a taste selection and providing a more flavorful smoking experience. It should be noted that in other embodiments, the cigarette device can only be provided with the first isolating member 2, and the seasoning is placed in the first isolating member 2, wherein the seasoning material of the seasoning can be a long-lasting fragrance granule, etc., and there is no need to provide the second isolating member 4 for placing the seasoning.

[0055] In summary, the cigarette rolling device can provide a DIY-style hand-rolled cigarette tube 1, cigarette holder 3 and tobacco material overall packaging method based on full respect for the user's usage habits, thereby enhancing the smoking experience.

[0056] The above embodiments are not exhaustive of the present invention, and there may be many other embodiments not listed. Any replacements and improvements made without violating the concept of the present invention are within the scope of protection of the present invention.
