A cigarette device

Abstract

This invention relates to a cigarette rolling device, comprising a housing and a drive unit that rotates relative to the housing. The housing is composed of an upper shell and a lower shell that can be opened and closed. Cigarette rollers are rotatably mounted on both the upper and lower shells. Each cigarette roller's outer circumferential surface facing a drive gear collectively encloses a cigarette rolling space. The drive unit rotates synchronously with the drive gear, driving each cigarette roller to rotate. A guide post is provided at one end of the cigarette rolling space, and the guide post has a through hole connecting the cigarette rolling space and the grinding space of the tobacco grinding section. By using the above technical solution, this invention, by providing a guide post at one end of the cigarette rolling space, allows the tobacco paper to be rolled into a circular empty tube structure when rotating within the cigarette rolling space. Furthermore, the through hole on the guide post allows tobacco to be fed into the paper tube after it is rolled, ensuring that the tobacco is rolled first and then filled, preventing it from falling out during the initial rotation and rolling process.

Description

Technical Field

[0001] This invention relates to the field of cigarette rolling equipment technology, and more particularly to a cigarette rolling device. Background Technology

[0002] Currently, manual cigarette rolling devices mainly follow the traditional process of filling and rolling. Users need to first lay tobacco or ground tobacco on the cigarette paper, and then roll it up by the device or by hand to form a cigarette. This traditional method has inherent defects: during the rolling process, the tobacco at the edge of the cigarette paper is very easy to fall off, causing waste and pollution; at the same time, the loose tobacco will undergo uncontrollable displacement when rolling, resulting in uneven compactness inside the final cigarette, which seriously affects the smoking experience and combustion consistency; in addition, the adhesion of the cigarette paper is also difficult due to direct contact with the tobacco.

[0003] To address the aforementioned issues, the existing patent document CN221104767U discloses a manual cigarette rolling device that integrates the tobacco grinding section with the cigarette rolling structure, simplifying the operation steps. However, this device is essentially still within the framework of the pre-filling and pre-rolling process: its workflow requires first placing the ground tobacco into a placement cavity surrounded by rollers, compacting it into strips, and then placing it into cigarette paper for rolling and wrapping. Therefore, it still cannot overcome the risk of uneven distribution of tobacco during the initial placement and pre-compaction process, as well as the risk of tobacco scattering from the paper edges at the beginning of the rolling process. At the same time, this solution cannot change the degree of tobacco compaction.

[0004] In summary, both basic manual cigarette rolling machines and integrated improvements like CN221104767U are limited by the logic of filling before rolling, which makes it difficult to avoid tobacco scattering and ensure even distribution. Therefore, the industry urgently needs an integrated cigarette rolling solution that can innovate the process sequence and completely avoid the above-mentioned inherent defects. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art. This invention provides a cigarette rolling device that solves the problems of easy tobacco scattering, uneven distribution, and unstable cigarette quality in the pre-filling and post-rolling type cigarette rolling device.

[0006] The technical solution of the present invention: a cigarette rolling device, comprising a housing and a drive unit that rotates relative to the housing, the housing being composed of an upper shell and a lower shell that can be opened and closed, cigarette rolling rollers being rotatably arranged on both the upper shell and the lower shell, each cigarette rolling roller being integrally or fixedly provided with a driven gear, the drive unit driving the driven gear to rotate, and the outer peripheral surface of each cigarette rolling roller collectively enclosing a cigarette rolling space; It also includes a tobacco grinding section disposed on the housing, the tobacco grinding section including a box body and a cover body disposed opposite to each other, the opposite surfaces of the box body and the cover body are provided with staggered blades, the box body and the cover body form a tobacco grinding space to accommodate the blades, the bottom of the box body is provided with a discharge port, one end of the cigarette space is provided with a guide post, the guide post is provided with a through hole, the through hole connects the cigarette space and the tobacco grinding space of the tobacco grinding section.

[0007] By adopting the above technical solution, a guide post is set at one end of the cigarette rolling space, and a filter tip can be placed at the other end. When the cigarette paper rotates in the cigarette rolling space, both ends can be rolled around the guide post and the filter tip respectively to form a circular empty tube structure. Furthermore, a through hole is opened on the guide post, so that after the empty paper tube is rolled, the tobacco can be fed into the paper tube through this hole. Thus, rolling the paper and filling the tobacco become two separate steps. Rolling first and then filling prevents the tobacco from falling out during the initial rotation and placement process and during the rolling process. As a result, the tobacco filling in the cigarette is uniform and the quality is stable. In addition, a tobacco grinding part is added to one side of the guide post. After the user opens the cover and adds tobacco, he / she closes the cover and rotates it. The interlaced blades cut the tobacco into pieces. The chopped tobacco falls out from the discharge port at the bottom and can fall into the through hole of the guide post into the cigarette rolling space, eliminating the trouble of preparing tobacco separately and making it more convenient to use.

[0008] A further feature of the present invention is that a funnel is provided at the bottom of the box body, and the outlet of the funnel is directly or indirectly connected to the through hole of the guide post. The funnel is movably mounted on the shell or detachably mounted on the shell.

[0009] With the above-mentioned further configuration, by setting a funnel between the box body and the guide column, the broken tobacco falling from the discharge port of the tobacco grinding section can be caught, concentrated, and accurately guided into the through hole on the guide column, thus preventing the tobacco from spilling outside.

[0010] A further feature of the present invention is that the funnel is movably mounted on the shell.

[0011] By adopting the above-described further configuration, a funnel that can be moved between the housing and the guide post is provided, which increases the options for the position of the subsequent drive unit, and the funnel can guide and connect the grinding section and the through hole of the guide post.

[0012] A further feature of the present invention is that a funnel is provided at the bottom of the box body, the outlet of the funnel is directly or indirectly connected to the through hole of the guide post, and the neck of the funnel extends into the cigarette space to form a guide post.

[0013] With the above-mentioned further configuration, by setting a funnel between the box body and the shell, the neck of the funnel can directly serve as a guide post while connecting the inside of the box body and the cigarette space, reducing the number of parts. At the same time, the outer surface of the guide post can be made smooth to avoid interference from the cigarette rolling action of each cigarette roller.

[0014] A further provision of the present invention: the driving unit includes a drive gear, the driving unit is rotatably disposed outside the housing, and the drive gear drives each driven gear to rotate; the driving unit is disposed at the other end of the housing where the guide post is disposed.

[0015] The above-mentioned further configuration is the first type of drive method. Its structure is that the drive unit is rotatably mounted on the outside of the housing. The drive unit is preferably a knob, and the transmission with the driven gear is realized through the driving gear. Thus, when the user turns the outer knob, the inner gear and cigarette roller can be directly driven to rotate. The structure is simple and reliable.

[0016] A further feature of the present invention is that the funnel is integrally or circumferentially fixedly provided with a drive gear, the drive gear drives each driven gear to rotate, and the drive unit is integrally or fixedly provided on the funnel.

[0017] A further improvement upon the above is the second type of drive mechanism, which integrates the funnel, drive gear, and drive unit into a single rotatable component. In this design, the drive unit can be a handle or knob located on the outside of the funnel. The user can directly rotate the funnel to simultaneously drive the drive gear, thereby driving each cigarette roller to perform the rolling process. Furthermore, the outlet of the funnel is indirectly connected to the through hole via a shaft hole, making this drive mechanism more compact.

[0018] A further feature of the present invention is that a drive gear is integrally or circumferentially fixedly mounted on the guide column, the neck of the funnel is fixedly engaged with the guide column in the circumferential direction, the drive gear drives each driven gear to rotate, and the drive unit is integrally or fixedly mounted on the funnel.

[0019] This is another implementation of the second driving method. In this structure, the driving gear and the guide column form a whole, and the driving part and the funnel form a whole. By fixing the funnel and the guide column in the circumferential direction, the driving part is rotated to realize the rotation of the driving gear, thereby driving each driven gear and the corresponding cigarette roller to rotate.

[0020] A further feature of the present invention is that the funnel and the shell are detachably connected by a snap-fit ​​structure. The snap-fit ​​structure includes a stop pin disposed on the inner wall of the upper or lower shell, and a stop plate integrally or fixedly disposed with the funnel. The stop plate is provided with a stop groove, which includes a wide groove section and a narrow groove section that are connected to each other. The diameter of the stop pin is between the groove width of the wide groove section and the groove width of the narrow groove section. The groove walls of the wide groove section and the narrow groove section are smoothly connected by an inclined surface. When the gear plate is inserted into the housing, the gear pin passes through the narrow groove section and then enters the wide groove section.

[0021] With the above-mentioned further design, the snap-fit ​​structure allows the funnel to be quickly and stably installed onto the housing, and it is circumferentially locked after installation, while being axially pullable. After the stop pin moves to the wide slot, it cannot overcome the elasticity of the stop plate to deform and enter the narrow slot without external force. Thus, when the funnel is inserted, it has an axial locking effect. During installation, simply push the funnel in and you will hear the feedback sound of the stop pin entering the wide slot to complete the detachable assembly, preventing it from falling off automatically. At the same time, under the application of external force, the stop pin enters the narrow slot through the inclined surface, which can make the funnel detach from the housing. At this time, the guide post can be pulled out, or the guide post and the funnel can be detached from the housing together. Then, the housing can be opened, the produced cigarette can be taken out, and the entire manual cigarette rolling process can be completed.

[0022] A further feature of the present invention is that a positioning groove for accommodating a gear pin is provided on the groove wall of the narrow groove segment, and a smooth chamfer is provided between the bottom of the positioning groove and the side wall of the narrow groove segment.

[0023] With the above-mentioned further configuration, by opening positioning grooves in the wall of the narrow groove section, the funnel pulling process has multiple positions. The funnel can be pulled out a certain distance or completely pulled out of the shell. When used in conjunction with the guide column, the positions can be divided into the guide column that can be pulled out a certain distance relative to the shell, which facilitates the removal of cigarettes, and the complete removal of the guide column for replacement and maintenance.

[0024] A further improvement of the present invention is that the outer surface of each cigarette roller is provided with anti-slip textures to increase friction.

[0025] Further, an anti-slip texture is applied to the surface of the cigarette roller. This anti-slip texture can be a fine axial straight line, a micro spiral pattern, a cross grid pattern, or a sandblasted / finely sanded matte surface. Its function is to increase friction, allowing the cigarette roller to firmly grip the cigarette paper and smoothly roll it up, preventing the cigarette paper from slipping.

[0026] A further feature of the present invention includes a pressure rod, the outer diameter of which is smaller than the inner diameter of the through hole, and the pressure rod extends into the cigarette space along the through hole.

[0027] A further improvement upon the above-mentioned design includes a pressure bar, which can be inserted through the through-hole after the tobacco is filled into the paper tube to compact the loose tobacco. Alternatively, it can be inserted into the cigarette rolling space through the funnel outlet and the through-hole to adjust the tightness of the rolled cigarette.

[0028] A further feature of the present invention is that the opening between the upper and lower shells is provided with a paper inlet for the cigarette paper to enter.

[0029] With the above-mentioned further design, a paper inlet is opened on the casing, giving the cigarette paper a clear entry point. After the user inserts the edge of the cigarette paper through the paper inlet, the cigarette rolling operation can begin. The progress of the cigarette rolling can be judged by whether all the cigarettes are rolled into the paper inlet, making the operation simpler and more accurate. Attached Figure Description

[0032] The technical solutions in this embodiment will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] It should be noted that in the description of this invention, all directional indications (such as up, down, forward, backward, etc.) are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0034] Furthermore, in this invention, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. In the description of this invention, "a number" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0035] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0036] Example 1: As Figure 1-9 As shown, this embodiment provides a cigarette rolling device, including a cylindrical shell 1; the shell 1 is formed by hinged upper shell 11 and lower shell 12 through a pivot, and can be opened and closed freely. When closed, its front edge forms a paper inlet 14 for inserting cigarette paper.

[0037] Several cigarette rollers 3 are rotatably arranged inside the housing 1. The cigarette rollers 3 are arranged along a circular structure, and the axial directions of each cigarette roller 3 can be arranged in parallel to form a cylindrical housing structure. In this embodiment, six cigarette rollers 3 are selected. Two adjacent cigarette rollers 3 are rotatably mounted on the upper shell 11 and four adjacent cigarette rollers 3 are rotatably mounted on the lower shell 12. When the shell 1 is closed, the inner side of the six cigarette rollers 3 forms a cigarette space 32 with a cylindrical or frustum-shaped structure. The outer surface of each cigarette roller 3 is processed with anti-slip texture. In this embodiment, the anti-slip texture is selected as axial straight texture.

[0038] A guide post 2 is provided at one end of the cigarette space 32. The guide post 2 is disposed on the housing 1 and can move along the axial direction of the guide post 2. The guide post 2 can be partially located in the cigarette space 32 or can be completely located in the cigarette space 32. In this embodiment, the guide post 2 is a hollow column structure or a hollow housing structure, and a through hole 21 is provided in its central axial direction to connect the outside of the housing 1 and the cigarette space 32.

[0039] This embodiment also includes a drive assembly, which is the first driving method. The drive assembly includes a drive gear 4 and driven gears 31 fixedly mounted on each cigarette roller 3. In this embodiment, the drive gear 4 is rotatably mounted on the end of the housing 1 away from the guide post 2 via a bearing. Each driven gear 31 meshes with the drive gear 4 and is arranged around the drive gear 4. At the same time, a drive part 41 is rotatably mounted on the outside of the housing 1. The drive part 41 is a knob structure and is directly fixedly connected to the drive gear 4. After the drive part 41 rotates, it drives all the driven gears 31 to rotate synchronously through the drive gear 4, thereby driving each cigarette roller 3 to rotate synchronously clockwise or counterclockwise along its own rotation axis to perform cigarette rolling. It should be noted that in this embodiment, the drive part 41 can also be an electric device. The output shaft of the electric device is connected to the drive gear 4. The user can drive the drive gear 4 to rotate by turning on the electric device, thereby realizing the rotation of each cigarette roller 3 to perform cigarette paper processing.

[0040] In this embodiment, the drive unit 41 is located at the other end of the housing 1 where the guide post 2 is located. When the user turns the outer knob, the internal drive gear 4 and cigarette roller 3 can be directly driven to rotate. The structure is simple and reliable.

[0041] In this embodiment, a funnel 5 is also included. The funnel 5 is an independent component. Its outlet is aligned with the through hole 21 of the guide post 2 at the port outside the housing 1. The funnel 5 is detachably connected to the housing 1 along the axial direction of the guide post 2 through a snap-fit ​​structure. Furthermore, the funnel 5 can be fixedly mounted on the housing 1, or it can be detachably connected to the lower housing 12 through a snap-fit ​​structure, as long as the tobacco can be guided.

[0042] Specifically, the buckle structure consists of a stop pin 13 fixed to the inner wall of the housing 1 and a stop plate 51 fixed to the inner wall of the funnel 5. The stop plate 51 is provided with a stop groove 52 with a straight structure. The stop groove 52 includes a wide groove section 521 and a narrow groove section 522 that are connected. The diameter of the stop pin 13 is between the groove width of the wide groove section 521 and the groove width of the narrow groove section 522. The groove walls of the wide groove section 521 and the narrow groove section 522 are smoothly connected by an inclined surface. When the stop plate 51 is inserted into the housing 1, the stop pin 13 passes through the narrow groove section 522 and then enters the wide groove section 521.

[0043] During installation, the funnel 5 is pushed into the housing 1 along the axial direction. At the same time, the stop plate 51 is inserted. During this process, the stop pin 13 first passes through the narrow groove section 522. Since the width of the narrow groove section 522 is smaller than the diameter of the stop pin 13, the stop plate 51 will be squeezed and undergo a slight deformation, allowing the stop pin 13 to pass through the narrow groove section 522 and enter the wide groove section 521. Once it enters the wide groove section 521, since the width of the groove here is larger than the diameter of the stop pin 13, the deformation of the stop plate 51 is restored, and the stop pin 13 is restricted in the wide groove section 521. At this time, the funnel 5 is locked axially without external force and cannot be easily removed, thus meeting the functional requirements of cigarette driving or tobacco guiding.

[0044] When disassembly is required, the funnel 5 is pulled outward along the axial direction, and the shift pin 13 moves in the wide groove section 521. In the shift groove 52, the connection between the wide groove section 521 and the narrow groove section 522 is provided with a smooth inclined surface. When sufficient external force is applied, the shift pin 13 can press the shift plate 51 along the inclined surface to deform it, thereby sliding into the narrow groove section 522 and finally disengaging from the narrow groove section 522, achieving quick disassembly.

[0045] Furthermore, a recessed positioning groove 53 is provided on the groove wall of the narrow groove section 522. The size of the positioning groove 53 is designed to accommodate the stop pin 13. The positioning groove 53 and the side wall of the narrow groove section 522 are smoothly transitioned by a chamfer, so that the buckle structure has two positions: the position of fully withdrawing the funnel 5 and the position of partially withdrawing it. It should be noted that the funnel 5 can drive the guide column 2 to be withdrawn or inserted into the housing 1 together, so as to facilitate the removal process after the cigarette making is completed.

[0046] This embodiment also includes a tobacco grinding section 6, which includes a box body 61 and a cover body 62 that are rotatably arranged relative to each other. The box body 61 is detachably connected to the top of the funnel 5 by a snap fastener. The inner end faces of the box body 61 and the cover body 62 are provided with staggered blades 63, thereby forming a tobacco grinding space between the box body 61 and the cover body 62. The bottom of the box body 61 has a discharge port 64. After the tobacco is chopped by the blades in the box body 61, it enters the funnel 5 through the discharge port 64 and is guided by the funnel 5 through the through hole 21 into the cigarette space 32. It should be noted that the through hole 21 of the guide post 2 can connect the tobacco grinding space and the cigarette space 32. This solution may also be without the funnel 5.

[0047] In this embodiment, a pressure rod 7 is also provided. The pressure rod 7 is inserted and fixed on the upper shell 11. After the upper shell 11 and the lower shell 12 are rotated and opened, the pressure rod 7 can be pulled out from the upper shell 11 for use. The pressure rod 7 is a straight rod with a diameter slightly smaller than the inner diameter of the through hole 21 of the guide post 2 and the outlet of the funnel 5, so as to pass through the outlet of the funnel 5 and the through hole 21 to compact the tobacco in the cigarette space 32.

[0048] Work process: Open the upper shell 11 to expose the cigarette space 32, take out the pressure rod 7, and put a filter into the end of the cigarette space 32 away from the guide post 2 so that it can abut against one end of the shell 1. Take a piece of cigarette paper, insert one end of it from the paper inlet 14, and make the paper end attach to the side of the filter and the guide post 2, with the other end to be glued facing outward. Rolling and shaping: Close the upper shell 11. The user rotates the drive part 41 outside the shell 1 in one direction. The drive part 41 drives the drive gear 4 to rotate, which in turn drives all driven gears 31 and cigarette roller 3 to rotate synchronously in the same direction. The cigarette roller 3 reliably grips the cigarette paper by means of the axial straight lines on its surface, and rolls it flat and evenly around the filter and guide post 2. When the rolling is almost completed and the end of the cigarette paper with glue is exposed at the paper inlet 14, glue is applied. Continue to rotate a little, and the glue surface is pressed and bonded to form a hollow paper tube with a filter at the right end and an open left end. The paper tube is wrapped around the guide post 2 and the filter. Then fill with tobacco: put the tobacco leaves into the box 61 of the tobacco grinding section 6, tighten the cover 62, rotate the cover 62, and the interlaced blades 63 inside will cut the tobacco into pieces. The shredded tobacco will fall directly through the discharge port 64 or fall into the funnel 5 below through the discharge port 64 after the user shakes the whole device. Some of the shredded tobacco will fall directly into the funnel 5 and pass through the through hole 21, while the remaining shredded tobacco accumulated in the funnel 5 can be pushed into the through hole 21 by shaking the whole device after removing the tobacco grinding section 6, or by pushing it with the pressure rod 7 after removing the tobacco grinding section 6. After passing through the through hole 21 of the guide column 2, the shredded tobacco will be poured into the pre-formed empty paper tube from one side. Finally, compact and remove the cigarette: Insert the pressure rod 7 into the cigarette space 32 through the opening of the through hole 21 or through the funnel 5 and the through hole 21 in sequence, and gently push it to the right to compress the loose tobacco in the paper tube to the required tightness. Then, open the upper shell 11, pull out the funnel 5 and the guide column 2, and you can take out the finished cigarette from the cigarette space 32 by hand.

[0049] It should be noted that when taking out the cigarette at the end, the funnel 5 and guide post 2 do not need to be pulled out. The finished cigarette can be taken out by simply deforming the cigarette paper rolled outside the guide post 2.

[0050] Example 2: Figure 10-15As shown, this embodiment provides a cigarette rolling device, including a housing 1. The housing 1 is still an upper shell 11 and a lower shell 12 that are hinged together and can be opened and closed. The overall structure is a frustum shape, which can be opened and closed freely. When closed, its front edge forms a paper inlet 14 for inserting cigarette paper. In this embodiment, cigarette rollers 3 are rotatably arranged on the upper shell 11 and the lower shell 12 respectively. All cigarette rollers 3 are arranged along the generatrix of the housing 1. In this embodiment, six cigarette rollers 3 are selected. Two adjacent cigarette rollers 3 are rotatably mounted on the upper shell 11 and four adjacent cigarette rollers 3 are rotatably mounted on the lower shell 12. When the housing 1 is closed, the inner side of the six cigarette rollers 3 forms a cigarette rolling space 32 with a frustum shape. The outer surface of each cigarette roller 3 is processed with anti-slip texture. In this embodiment, the anti-slip texture is axial straight groove.

[0051] In this embodiment, a guide post 2 is also provided. The guide post 2 is located at one end of the cigarette space 32. The guide post 2 is inserted into the housing 1 and can move along the axial direction of the guide post 2. The guide post 2 can be partially located in the cigarette space 32 or it can be completely located in the cigarette space 32. Preferably, the guide post 2 is a hollow column structure or a hollow housing structure, and its central axial direction is provided with a through hole 21 to connect the outside of the housing 1 and the cigarette space 32.

[0052] Similar to Embodiment 1, this embodiment also includes a funnel 5 and a tobacco grinding section 6. The funnel 5 is rotatably mounted outside the housing 1, specifically on the lower housing 12. The tobacco grinding section 6 is detachably mounted on the funnel 5. The tobacco grinding section 6 includes a box body 61 and a cover 62 that are rotatably mounted relative to each other. The box body 61 is detachably connected to the top of the funnel 5 by a snap fastener. The inner end faces of the box body 61 and the cover 62 are provided with staggered blades 63, thereby forming a tobacco grinding space between the box body 61 and the cover 62. The bottom of the box body 61 has a discharge port 64. After the tobacco is chopped by the blades inside the box body 61, it enters the funnel 5 through the discharge port 64 and is guided by the funnel 5 into the through hole 21, and falls into the cigarette space 32.

[0053] This embodiment also includes a drive assembly, which is the second driving method. The drive assembly includes a drive gear 4 and a driven gear 31 fixedly disposed on each cigarette roller 3. In this embodiment, the driven gear 31 is rotatably disposed at one end of the housing 1 near the funnel 5. The main difference between this embodiment and the first embodiment is that the drive gear 4 and the funnel 5 are configured as a single rotatable part. The funnel 5 is rotatably mounted on the lower housing 12. In this embodiment, the drive part 41 is integrally formed on the outer periphery of the funnel 5. The user can directly rotate the funnel 5 to simultaneously drive the drive gear 4 to rotate, thereby driving each cigarette roller 3 to perform the paper rolling operation, resulting in a more compact structure.

[0054] In this embodiment, when the driving gear 4, the guide post 2, and the funnel 5 are separately arranged, and the driving gear 4 is fixedly mounted on the neck of the funnel 5, the rotation center of the driving gear 4 is provided with a shaft hole 42 that extends vertically; the shaft hole 42 has multiple connection schemes with the guide post 2 and the neck of the funnel 5: In the first scheme, the outlet neck of the funnel 5 and the guide post 2 are both inserted into the shaft hole 42, and the driving gear 4 is circumferentially fixed to the outer periphery of the outlet neck of the funnel 5. The outlet of the funnel neck is simultaneously inserted into the shaft hole 42 of the driving gear 4. The neck of the funnel 5 and the shaft hole 42 are locked in the circumferential direction. The upper end of the shaft hole 42 is connected to the cavity of the funnel 5, and the lower end is aligned with the through hole 21 of the guide post 2, so that the through hole 21 of the guide post 2 is indirectly connected to the outlet of the funnel 5. This scheme is the preferred scheme. It should be noted that another possibility of this scheme is that the guide post 2 can be inserted into the housing 1, and only the through hole 21 needs to be connected to the shaft hole 42.

[0055] In the second embodiment, the neck of the funnel 5 is fixed in the shaft hole 42, the guide post 2 is inserted in the funnel 5, and the through hole 21 still connects the tobacco grinding space and the cigarette rolling space 32. In the third scheme, the guide post 2 is inserted into the shaft hole 42 and fixed in the circumferential direction, while the neck of the funnel 5 is inserted into the through hole 21 of the guide post 2. At the same time, the funnel 5 can rotate in the circumferential direction. This scheme can also realize the setting of the through hole 21 connecting the tobacco grinding space and the cigarette space 32. All three connection schemes mentioned above are acceptable. It is only necessary to ensure that the through hole 21 connects the tobacco grinding space and the cigarette rolling space 32, while the funnel 5 is not fixed in the circumferential direction and can rotate, and the funnel 5 and the driving gear 4 are fixed in the circumferential direction.

[0056] When the driving gear 4 is integrally or circumferentially fixed to the guide post 2, the neck of the funnel 5 is fixedly engaged with the guide post 2 in the circumferential direction. The driving gear 4 drives each driven gear 31 to rotate. The drive unit 41 can still be integrally or fixedly mounted on the funnel 5. Thus, the driving gear 4 and the guide post 2 form a whole, and the drive unit 41 and the funnel 5 form a whole. Through the fixed engagement of the funnel 5 and the guide post 2 in the circumferential direction, the rotation of the drive unit 41 can realize the rotation of the driving gear 4.

[0057] When the neck of the funnel 5 can extend into the cigarette space 32 to directly form the guide post 2, this scheme optimizes the number of parts. The drive gear 4 can be fixed or integrally set outside the funnel 5. At the same time, the outer surface of the guide post 2 can be set as a smooth surface to avoid interfering with the cigarette rolling action of each cigarette roller 3.

[0058] Similar to Embodiment 1, in this embodiment, the grinding part 6 is detachably mounted on the top of the funnel 5 via a snap-fit ​​mechanism.

[0059] In this embodiment, a pressure rod 7 is also provided. The pressure rod 7 can be inserted and fixed on the upper shell 11 or can be separated from the shell 1. After the upper shell 11 and the lower shell 12 are rotated and opened, the pressure rod 7 can be pulled out from the upper shell 11 for use. The pressure rod 7 is a straight rod with a diameter slightly smaller than the inner diameter of the through hole 21 of the guide post 2 and the outlet of the funnel 5, so as to pass through the outlet of the funnel 5 and the through hole 21 to compact the tobacco in the cigarette space 32.

[0060] Overall, the workflow of this embodiment is consistent with that of Embodiment 1: Open the upper shell 11 to expose the cigarette space 32, and put a filter tip into the end of the cigarette space 32 away from the guide post 2 so that it abuts against one end of the shell 1. Take a piece of cigarette paper, insert one end of it from the paper inlet 14, and attach the paper head to the side of the filter tip and the guide post 2, with the other end facing outwards to be coated with glue. Rolling and shaping: Close the upper shell 11, and the user rotates the drive unit 41 outside the shell 1 in one direction. The core difference in operation is that the user does not rotate an independent knob, but directly holds and rotates the outer wall of the funnel 5, i.e., the drive unit 41. This action drives the cigarette rollers 3 to rotate and roll the paper through the drive gear 4 on it. Similar to Embodiment 1, the drive unit 41 can also be an electric device. The electric device can be fixedly installed on the side wall of the shell 1, and its output shaft is connected to the drive funnel 5, thereby driving the drive gear 4 to rotate, and finally driving each cigarette roller 3 to rotate and roll the paper.

[0061] Then fill with tobacco: put the tobacco leaves into the box 61 of the tobacco grinding section 6, tighten the cover 62, rotate the cover 62, and the interlaced blades 63 inside will cut the tobacco into pieces. The shredded tobacco will fall directly through the discharge port 64 or fall into the funnel 5 below through the discharge port 64 after the user shakes the whole device. Some of the shredded tobacco will fall directly into the funnel 5 and pass through the through hole 21, while the remaining shredded tobacco accumulated in the funnel 5 can be pushed into the through hole 21 by shaking the whole device or by pushing it with the pressure rod 7 after removing the tobacco grinding section 6. After passing through the through hole 21 of the guide column 2, the shredded tobacco will be poured into the already formed empty paper tube from one side. Finally, compaction and cigarette removal: After removing the tobacco grinding part 6 from the housing 1, insert the pressure rod 7 into the cigarette space 32 through the opening of the through hole 21 or through the funnel 5 and the through hole 21 in sequence, and gently push to compress the loose tobacco in the paper tube to the required tightness. Then, open the upper housing 11 and push the guide post 2 outward a distance. The complete cigarette can then be removed from the cigarette space 32 by hand. Alternatively, it is not necessary to push the guide post 2; simply deform the tobacco paper rolled outside the guide post 2 to remove it.
