Abstract
Description
Technical Field
[0001] This utility model relates to the field of cigarette butt collection, and further to a cigarette butt recycling device. Background Technology
[0002] Traditional cigarette butt bins mostly use a cylindrical structure that matches the outer shell, a design with significant drawbacks. The relatively large internal space of the cylindrical structure hinders air circulation, causing smoke from partially extinguished cigarette butts to linger and not dissipate quickly enough. The smoke continues to be produced before the cigarette butts self-extinguish, polluting not only the air inside the bin but also escaping into the surrounding environment through gaps, causing air pollution. Furthermore, harmful substances in the smoke, such as tar and nicotine, remain and adhere to the inner walls of the bin, forming difficult-to-clean grime and increasing the difficulty and cost of cleaning and maintenance. In addition, the residual heat from partially extinguished cigarette butts can create a fire hazard if a large number of cigarette butts accumulate inside, threatening public safety. The lack of effective cigarette butt extinguishing and smoke treatment mechanisms in the cylindrical structure makes the extinguishing process slow and difficult to quickly eliminate the source of pollution. Utility Model Content
[0003] To address the aforementioned technical problems, the purpose of this utility model is to provide a cigarette butt recycling device. The sliding walls of the collection channel in the cigarette butt recycling device are configured to gradually converge towards each other along the direction in which the cigarette butts fall. When a cigarette butt enters the inlet, it falls onto the gradually converging sliding walls and extinguishes itself as it rolls down the sliding walls. This method more effectively utilizes limited space to promote the extinguishing of cigarette butts, thereby reducing fire hazards, minimizing continuous smoke pollution, and improving the safety of the cigarette butt recycling device.
[0004] To achieve the above objectives, this utility model provides a cigarette butt recycling device, including a housing and a collection channel. The housing is provided with a placement cavity, the top of the placement cavity is provided with a dispensing port, and the placement cavity is also provided with a cigarette butt box.
[0005] The collection channel is disposed in the placement cavity and connects the delivery port and the cigarette butt box. The collection channel includes a sliding part, and the sliding part includes at least a pair of sliding walls. The pair of sliding walls gradually move closer to each other along the falling direction of the cigarette butts, so that the cross-section of the collection channel gradually decreases.
[0006] When a cigarette butt enters the inlet, it falls onto the sliding wall and is extinguished as it rolls down the wall.
[0007] In some embodiments, the sliding part includes a pair of sliding walls and a pair of connecting walls. The pair of sliding walls are disposed on both sides of the housing in the left-right direction and are close to each other. The connecting walls are disposed on both sides of the housing in the front-back direction and connect the pair of sliding walls.
[0008] In some embodiments, the sliding part includes two pairs of sliding walls. One pair of sliding walls is disposed in the left-right direction of the housing and close to each other, and the other pair of sliding walls is disposed on both sides of the housing in the front-back direction and close to each other. The two pairs of sliding walls have different inclination angles.
[0009] In some embodiments, the sliding walls extend linearly along the direction of the cigarette butt's descent and gradually converge, so that a pair of sliding walls form a symmetrically converging sliding slope.
[0010] In some embodiments, the collection channel further includes a guide portion disposed at the end of the sliding portion, the guide portion including a plurality of vertically arranged guide walls, the guide walls being vertically connected to the cigarette butt box so that the cigarette butts enter the cigarette butt box vertically.
[0011] In some embodiments, a cover plate is also included, which is detachably disposed above the inlet of the placement cavity. The cover plate is provided with a plurality of collection holes, which communicate with the inlet and match the sliding wall of the collection channel.
[0012] In some embodiments, the inner wall of the placement cavity matches the outer wall of the sliding portion of the collection channel;
[0013] The housing is also provided with an installation groove on the outside of the dispensing port, and the cover plate can be detachably installed in the installation groove.
[0014] In some embodiments, the cover plate is disposed on the housing in an inclined state, and the inclined direction of the cover plate gradually increases from the front end of the housing to the rear end of the housing.
[0015] In some embodiments, the collection channel further includes a connecting portion disposed above the sliding portion, the connecting portion including a plurality of connecting walls, the connecting walls being perpendicularly connected to the cover plate.
[0016] In some embodiments, a detection device is also included, which is located at the bottom of the collection channel or the top of the cigarette butt box, for detecting the number of cigarette butts and sending the data to the background cloud for processing.
[0017] Compared with the prior art, the cigarette butt recycling device provided by this utility model has at least one of the following beneficial effects:
[0018] 1. The sliding walls of the collection channel in the cigarette butt recycling device are designed to gradually move closer together along the direction in which the cigarette butts fall. When the cigarette butts enter the inlet, they fall onto the gradually moving sliding walls and are extinguished as they roll down the sliding walls. This method can make more effective use of the limited space to promote the extinguishing of cigarette butts, thereby reducing fire hazards, reducing continuous smoke pollution, and improving the safety of the cigarette butt recycling device.
[0019] 2. The sliding wall adopts a straight sliding slope, starting from the feeding port and extending linearly along the direction of the cigarette butt's descent, gradually converging towards the center line at a uniform rate. This ensures that the sliding wall forms a symmetrical and converging sliding slope along its entire length, allowing the cigarette butt to maintain a stable trajectory during the sliding process. The guide section can efficiently guide the cigarette butt from the sliding section into the cigarette butt box, ensuring that the cigarette butt enters the cigarette butt box vertically, avoiding possible deviation, jamming, or breakage problems during the entry process.
[0020] 3. The cover is detachably mounted on the housing, allowing it to be easily removed from above the dispensing port of the placement chamber. This facilitates individual replacement and cleaning of the cover, and also makes it easier to clean and maintain the dispensing port and the collection channel below.
[0021] 4. The cover is set on the housing at an angle, with the angle gradually rising from the front end of the housing to the rear end, making it more convenient for smokers to dispose of cigarette butts, while preventing rainwater or other liquids from accumulating on the cover.

[0033] refer to Figure 1This utility model provides a cigarette butt recycling device, including a housing 1 and a collection channel 2. The housing 1 is provided with a placement cavity, and the top of the placement cavity is provided with a dispensing port 10. The placement cavity is also provided with a cigarette butt box 11. The collection channel 2 is disposed in the placement cavity and connects the dispensing port 10 and the cigarette butt box 11. The collection channel 2 includes a sliding part 21, and the sliding part 21 includes at least a pair of sliding walls 211. The pair of sliding walls 211 gradually move closer to each other along the falling direction of the cigarette butt, so that the cross-section of the collection channel 2 gradually decreases. When the cigarette butt enters the dispensing port 10, the cigarette butt falls onto the sliding wall 211 and is extinguished as it rolls down the sliding wall 211.
[0034] In this embodiment, the sliding walls 211 of the collection channel 2 in the cigarette butt recycling device are configured to gradually move closer together along the falling direction of the cigarette butts. When the cigarette butts enter the inlet 10, they fall onto the gradually moving sliding walls 211 and are extinguished as they roll down the sliding walls 211. This can more effectively utilize the limited space to promote the extinguishing of cigarette butts, thereby reducing fire hazards, reducing continuous smoke pollution, and improving the safety of the cigarette butt recycling device.
[0035] Specifically, the housing 1 has a placement cavity with a dispensing port 10 at the top and a cigarette butt box 11 for collecting cigarette butts at the bottom. A collection channel 2 is located within the placement cavity and has a hollow structure that connects the dispensing port 10 and the cigarette butt box 11, allowing cigarette butts to smoothly enter the collection channel 2 from the dispensing port 10 and slide into the cigarette butt box 11. The key feature of this application is that the sliding portion 21 of the collection channel 2 includes at least a pair of sliding walls 211. These sliding walls 211 gradually approach each other along the direction in which the cigarette butt falls, thus gradually reducing the cross-sectional area of the collection channel 2. When a cigarette butt is placed into the dispensing port 10, it lands steadily on these gradually approaching sliding walls 211. As the cigarette butt rolls and slides down the sliding walls 211, it fully contacts the walls and gradually cools down, effectively extinguishing the ash. Furthermore, as the cross-section of collection channel 2 gradually decreases, cigarette butts are guided to a relatively concentrated area during the rolling process, which facilitates subsequent collection and cleaning, helps keep the inside of the device clean, and reduces the workload of cleaning and maintenance.
[0036] It is worth noting that the sliding wall 211 creates favorable conditions for the extinguishing of cigarette butts, promotes the extinguishing process to the greatest extent, greatly reduces the fire hazard that may be caused by incomplete extinguishing of cigarette butts, and also reduces environmental pollution caused by continuous smoke emission. This significantly improves the safety of the cigarette butt recycling device during use and provides a strong guarantee for the cleanliness and safety of the public environment.
[0037] Preferably, refer to Figure 2 and Figure 3The sliding part 21 includes a pair of sliding walls 211 and a pair of connecting walls. The pair of sliding walls 211 are disposed on both sides of the housing 1 in the left-right direction and are close to each other. The connecting walls are disposed on both sides of the housing 1 in the front-back direction and connect the pair of sliding walls 211.
[0038] In this embodiment, the sliding walls 211 are respectively installed on the left and right sides of the housing 1, symmetrically distributed, and gradually converge towards the center line from top to bottom along the natural falling trajectory of the cigarette butt, forming a gradually narrowing V-shaped channel. This ensures smooth sliding of the cigarette butt and achieves physical extinguishing through moderate friction. The tilt angle of the sliding walls 211 is not further limited here, as long as it ensures that the cigarette butt slides down at a suitable speed and avoids rebound due to excessive tilt or poor sliding due to insufficient tilt. The key to this embodiment is that the sliding walls 211 adopt a gradually narrowing V-shaped design. Starting from the inlet 10, the sliding walls 211 on both sides gradually converge towards the center line along the falling direction of the cigarette butt. This not only guides the cigarette butt to slide smoothly into the cigarette butt box 11, but also increases the contact area between the cigarette butt and the wall surface through the gradually decreasing channel space, ensuring that the cigarette butt is extinguished by friction during rolling.
[0039] In a modified embodiment, the sliding part 21 includes two pairs of sliding walls 211. One pair of sliding walls 211 is located in the left-right direction of the housing 1 and is close to each other, while the other pair of sliding walls 211 is located on both sides of the housing 1 in the front-back direction and is close to each other. The two pairs of sliding walls 211 have different inclination angles. These different inclination angles create a unique three-dimensional tapering channel, significantly improving the extinguishing effect of cigarette butts. For example, the left-right sliding walls 211 form a 30° angle with the horizontal plane, allowing the cigarette butt to slide quickly and stably along the wall under gravity. The front-back sliding walls 211 form a 45° angle with the horizontal plane; this larger inclination angle aims to provide a steeper sliding path for the cigarette butt, thereby achieving complete extinguishing of the cigarette butt in a shorter distance. The two pairs of sliding walls 211 intersect each other in space, forming a diamond-shaped tapering channel. As the cigarette butt slides down the left-right sliding wall 211, guided by the front-back sliding wall 211, it undergoes complex rolling and sliding in three-dimensional space. This multi-dimensional motion path maximizes the contact area between the cigarette butt and the wall surface during sliding, thus significantly improving extinguishing efficiency. Of course, the inclination angles of the two pairs of sliding walls 211 can also be equal. In this case, the cross-section of the collection channel 2 is proportionally reduced, and both pairs of sliding walls 211 move towards the center from the dispensing port 10, forming a "convex" shaped channel that is low in the middle and high on both sides.
[0040] Preferably, the sliding wall 211 extends linearly along the direction of the cigarette butt's downward movement and gradually converges, so that a pair of sliding walls 211 form a symmetrical and converging sliding slope.
[0041] In this embodiment, the sliding wall 211 adopts a straight sliding slope, starting from the feeding port 10 and extending linearly along the direction of the cigarette butt's downward movement, and gradually approaching the center line at a uniform rate. This ensures that the sliding wall 211 forms a symmetrical and converging sliding slope over its entire length, so that the cigarette butt always maintains a stable trajectory during the sliding process.
[0042] Specifically, a pair of sliding walls 211 extend linearly along the direction of the cigarette butt's descent and gradually converge, forming a symmetrically converging sliding slope. The straight sliding walls 211 evenly distribute the force, enhancing the overall structural strength. Even under significant impact, the sliding walls 211 remain stable and resistant to deformation during the cigarette butt's descent. As the sliding walls 211 converge, the cross-section of the collection channel 2 gradually decreases, maximizing the contact area between the cigarette butt and the sliding walls 211. This ensures the cigarette butt fully contacts the wall surface during sliding, achieving physical extinguishing through friction. Furthermore, the symmetrically converging sliding slope provides a stable sliding path for the cigarette butt, reducing tumbling and deviation during the descent, further improving extinguishing efficiency. Simultaneously, the straight sliding walls 211 simplify the manufacturing process, reduce production costs, and facilitate regular cleaning and maintenance, minimizing the complexity of maintenance work.
[0043] It is worth noting that the sliding wall 211 can also adopt an arc-shaped structure, which causes the contact point between the cigarette butt and the wall surface to change continuously during the sliding process, forming multi-point contact, increasing friction, and ensuring that the cigarette butt can fully rub against the wall during the sliding process to achieve physical extinguishing. Moreover, the arc-shaped sliding wall 211 generates local pressure changes when the cigarette butt slides, forcing the cigarette butt to fit tightly against the wall surface of the sliding wall 211 in certain areas, further enhancing the friction effect. This pressure change helps to lower the temperature of the cigarette butt more quickly, ensuring that it is completely extinguished before entering the cigarette butt box 11.
[0044] Furthermore, the collection channel 2 also includes a guide section 22 disposed at the end of the sliding section 21. The guide section 22 includes several vertically arranged guide walls, which are vertically connected to the cigarette butt box 11 so that the cigarette butts enter the cigarette butt box 11 vertically.
[0045] In this embodiment, the guide part 22 can efficiently guide the cigarette butt from the sliding part 21 into the cigarette butt box 11, ensuring that the cigarette butt enters the cigarette butt box 11 vertically, and avoiding the problems of deviation, jamming or breakage that may occur during the entry of the cigarette butt.
[0046] Specifically, the guide wall extends vertically downwards from the end of the sliding section 21, tightly engaging with the inlet of the cigarette butt box 11. This ensures that after the cigarette butts enter the guide section 22 at the end of the sliding section 21, they can accurately fall vertically into the cigarette butt box 11. The vertical arrangement of the guide wall ensures that the cigarette butts will not experience unnecessary friction or rebound due to the sliding of the sliding wall 211 during the sliding process, allowing the cigarette butts to enter the cigarette butt box 11 vertically via the shortest path. This not only improves the reliability of the cigarette butt recycling device but also enhances its safety and ease of maintenance.
[0047] It is worth noting that a docking structure can also be provided at the entrance of the cigarette butt box 11 to ensure that the cigarette butts can fall accurately into the cigarette butt box 11. The docking structure can be a groove, so that the opening of the cigarette butt box 11 matches the guide part 22 precisely, ensuring that the cigarette butts will not deviate when entering the cigarette butt box 11.
[0048] Further, refer to Figure 1 and Figure 2 It also includes a cover plate 3, which is detachably disposed above the inlet 10 of the placement cavity. The cover plate 3 is provided with a plurality of collection holes 31, which are connected to the inlet 10 and matched with the sliding wall 211 of the collection channel 2.
[0049] In this embodiment, the cover plate 3 is detachably mounted on the housing 1, which can be easily removed from the top of the placement port 10 of the placement cavity, making it convenient to replace and clean the cover plate 3 separately. It also facilitates the cleaning and maintenance of the placement port 10 and the collection channel 2 below it.
[0050] Specifically, the cover plate 3 is provided with several collection holes 31, which communicate with the inlet 10 and match the sliding wall 211 of the collection channel 2. This ensures that cigarette butts can pass smoothly and enter the collection channel 2 along the sliding wall 211, while preventing cigarette butts from accumulating or getting stuck at the inlet 10. The cover plate 3 not only seals the inlet 10 but also prevents foreign objects from entering the collection channel 2, protecting the internal structure from damage. In addition, the collection holes 31 on the cover plate 3 can also prevent children or pets from accidentally ingesting cigarette butts. Preferably, the inner sidewall of the placement cavity matches the outer sidewall of the sliding part 21 of the collection channel 2; the housing 1 also has an installation groove on the outside of the inlet 10, and the cover plate 3 can be detachably installed in the installation groove. It is worth noting that the cover plate 3 can be fixed to the housing 1 by means of snap-fit, bolt, or magnetic connection. Snap-fit connection facilitates quick assembly and disassembly, bolt connection provides a more stable fixing effect, while magnetic connection combines ease of assembly and disassembly with a certain fixing strength. In practical applications, the appropriate connection method can be selected according to specific needs and the usage environment.
[0051] Preferably, the cover plate 3 is inclined on the housing 1, and the inclined direction of the cover plate 3 is gradually rising from the front end of the housing 1 to the rear end of the housing 1.
[0052] In this embodiment, the cover plate 3 is inclined on the housing 1, and the inclination direction gradually rises from the front end of the housing 1 to the rear end of the housing 1, which makes it more convenient for smokers to dispose of cigarette butts, while preventing rainwater or other liquids from accumulating on the cover plate 3.
[0053] Specifically, the tilt of the cover 3 is more ergonomic, allowing smokers to dispose of cigarette butts with a natural gesture while standing, reducing bending or reaching movements and improving comfort. The tilt of the cover 3 also enhances its protective function, effectively preventing rainwater, dust, and other foreign objects from entering the placement chamber. In rainy outdoor environments, it ensures that rainwater quickly slides off, preventing water accumulation and damage to the internal structure of the device. The tilt of the cover 3 also allows it to more effectively guide cigarette butts into the disposal opening 10. The front end of the cover 3 has a slight guiding slope, smoothly transitioning with the disposal opening 10, ensuring that cigarette butts slide smoothly into the collection channel 2. The collection channel 2 may further include a connecting part 23, located above the sliding part 21. The connecting part 23 includes several connecting walls that are perpendicularly connected to the cover 3. This perpendicular connection not only enhances the stability of the cover 3 but also ensures that cigarette butts smoothly enter the sliding part 21 from the collection hole 31 of the cover 3. This connecting wall can also act like a guide slope, helping cigarette butts to slide smoothly into the channel and reducing resistance when they enter.
[0054] Furthermore, it also includes a detection device 4, which is installed at the bottom of the collection channel 2 or the top of the cigarette butt box 11. The detection device 4 is used to detect the number of cigarette butts and send the data to the cloud for processing. The detection device 4 is used to monitor the number of cigarette butts passing through in real time and transmit the data to an external control system. When the number of cigarette butts in the cigarette butt box 11 is detected to be close to full, the system will issue a warning signal to remind staff to clean the cigarette butt box 11 in time. Of course, the detection device 4 can also be installed near the top of the connecting wall of the connecting part 23. The detection device 4 includes, but is not limited to, miniature photoelectric sensors, ultrasonic sensors, infrared sensors, etc., and this application does not further limit it.
[0055] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this utility model. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
