Description

Technical Field

[0001] This utility model relates to the field of intelligent ashtray technology, specifically to a smoke extinguishing mechanism and ashtray suitable for a rotating roller. Background Technology

[0002] As an emerging electronic product, smart ashtrays can automatically extinguish cigarettes after the user throws them in.

[0003] The applicant's prior patent applications CN202222598096.9 and CN202320559576.6 both disclose the use of a pair of rotating bodies to squeeze the cigarette butt to extinguish the smoke. The latter also discloses a smoke extinguishing peeling structure that can effectively and promptly peel off and clean the residue on the outer wall of the rotating body. However, due to the difference in the structure of the rotating body, the smoke extinguishing peeling structure of the latter is not applicable to the former.

[0004] Therefore, we propose a smoke extinguishing mechanism and ashtray suitable for the form of a rotating roller. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] This utility model provides a smoke extinguishing mechanism and ashtray suitable for a rotating roller type, which can solve the technical problems of existing rotating roller type smoke extinguishing mechanisms, such as ash adhesion and accumulation, cigarette butt residue, which affect the subsequent smoke extinguishing effect, and may even cause the smoke extinguishing mechanism to jam and become unusable.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A smoke extinguishing mechanism suitable for a rotating roller type includes a smoke extinguishing structure and a dust removal structure; characterized in that:

[0010] The smoke extinguishing structure includes a smoke extinguishing rotating roller and a driving unit. The smoke extinguishing rotating roller rotates under the action of the driving unit and squeezes the cigarette butt to extinguish the smoke.

[0011] The ash removal structure includes a cleaning roller arranged parallel to the smoke extinguishing roller. The surface of the cleaning roller is covered with bristles that abut against the surface of the smoke extinguishing roller. The cleaning roller moves back and forth along its own axis under the drive of the reciprocating structure.

[0012] Furthermore, the cleaning roller can be driven to rotate while performing reciprocating translational motion.

[0013] Furthermore, the smoke extinguishing mechanism also includes a cigarette butt conveying structure;

[0014] The cigarette butt conveying structure includes a conveyor belt, a driving conveyor roller, and a driven conveyor roller. The conveyor belt passes around the driving conveyor roller and the driven conveyor roller and is driven by the driving conveyor roller.

[0015] The extinguishing roller works in conjunction with the active conveying roller to crush the cigarette butt.

[0016] Furthermore, the extinguishing roller includes a primary extinguishing roller and a secondary extinguishing roller arranged in parallel.

[0017] The cleaning roller makes contact with the surfaces of the primary and secondary smoke-extinguishing rollers simultaneously through bristles in different areas.

[0018] Furthermore, the extinguishing roller and the cleaning roller are respectively supported on the support, and the roller shaft of the cleaning roller can be slidably arranged relative to the support.

[0019] Furthermore, the reciprocating structure includes a ball head, a rotary wheel, and a spring. The cleaning roller has a ball head on one side of its journal and a spring on the other side of its journal. The rotary wheel is rotatably mounted and has a concave-convex part on its end face arranged around its own axis. Under the action of the spring, the ball head and the concave-convex part remain in contact. When the rotary wheel rotates, the cleaning roller is driven to reciprocate along its own axis through the cooperation between the concave-convex part and the ball head.

[0020] Furthermore, the drive unit uses a motor and drives the active conveying roller, the smoke extinguishing roller and the return wheel to rotate synchronously through a gear transmission unit.

[0021] Furthermore, the surface of the primary smoke-extinguishing roller is provided with primary ribs, which cooperate with the active conveying roller to crush the cigarette butt;

[0022] The primary rib extends from one end of the primary smoke-extinguishing roller to the other end and is spirally arranged around the axis of the roller.

[0023] Alternatively, the primary rib extends from one end of the primary smoke-extinguishing roller to the other end and is arranged parallel to the roller axis.

[0024] Furthermore, the secondary smoke-extinguishing roller is provided with secondary ribs, which cooperate with the active conveying roller to crush the cigarette butt. The secondary ribs extend from one end of the secondary smoke-extinguishing roller to the other end and are arranged parallel to the axis of the roller.

[0025] The distance from the primary rib to the active conveyor roller is greater than the distance from the secondary rib to the active conveyor roller.

[0026] Preferably, the distance from the primary rib to the active conveyor roller is greater than the distance from the secondary rib to the active conveyor roller.

[0027] Furthermore, the end of the primary smoke-extinguishing roller is connected to a first transmission gear, the end of the secondary smoke-extinguishing roller is connected to a second transmission gear, the end of the active conveying roller is connected to a third transmission gear, and the output end of the motor is connected to a main transmission gear. The main transmission gear, the third transmission gear, the first transmission gear, the second transmission gear, and the rotary wheel mesh and drive each other.

[0028] This utility model also provides an ashtray that includes the above-mentioned smoke extinguishing mechanism.

[0029] (III) Beneficial Effects

[0030] This utility model provides a smoke extinguishing mechanism and ashtray suitable for a rotating roller type, which has the following beneficial effects:

[0031] (1) The brush bristles of the cleaning roller rub against the extinguishing roller. This friction includes the lateral friction generated by the reciprocating translational motion of the cleaning roller along its own axis and the radial friction generated when the extinguishing roller rotates. By combining the lateral friction and the radial friction, the ash and residual cigarette butts adhering to the extinguishing roller are cleaned up in a timely and effective manner, so that the surface of the extinguishing roller is always kept clean and tidy, so as to avoid the extinguishing mechanism from getting stuck and ensure the reliability of the extinguishing mechanism in long-term use.

[0032] (2) The primary ribs on the primary smoke extinguishing roller are spirally arranged relative to the axis. On the one hand, the gap between the primary ribs and the active conveying roller changes during the rotation of the primary smoke extinguishing roller, making it easier to roll up the cigarette butt and less likely to cause the cigarette butt to not be rolled up or to spin. On the other hand, it is also easier to drive the brush and cleaning roller to rotate. Attached Figure Description

[0058] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0059] See attached document Figure 1-6 A smoke extinguishing mechanism suitable for a rotating roller form includes a smoke extinguishing structure and a dust removal structure;

[0060] The smoke extinguishing structure includes a primary smoke extinguishing roller 7 and a secondary smoke extinguishing roller 8 arranged in parallel and rotating manner. The primary smoke extinguishing roller 7 and the secondary smoke extinguishing roller 8 rotate under the action of the drive unit 1 and squeeze the cigarette butt to extinguish the smoke.

[0061] The cleaning structure includes a cleaning roller 6 arranged parallel to the primary smoke-extinguishing roller 7 and the secondary smoke-extinguishing roller 8. During the reciprocating translation of the cleaning roller 6, the bristles maintain a relatively constant friction to clean the primary smoke-extinguishing roller 7 and the secondary smoke-extinguishing roller 8, ensuring the stability and reliability of the cleaning process. The cleaning roller 6 has bristles distributed on its surface, which contact the surfaces of the primary smoke-extinguishing roller 7 and the secondary smoke-extinguishing roller 8. Driven by the reciprocating structure, the cleaning roller 6 performs a reciprocating translational motion along its own axis while simultaneously rotating under the influence of the primary smoke-extinguishing roller 7 and the secondary smoke-extinguishing roller 8.

[0062] The device also includes a cigarette butt conveying structure, which includes a conveyor belt 12, an active conveyor roller 13 and a driven conveyor roller 15. The conveyor belt 12 passes around the active conveyor roller 13 and the driven conveyor roller 15 and is driven by the active conveyor roller 13.

[0063] The primary smoke-extinguishing roller 7 is positioned above the active conveying roller 13, the secondary smoke-extinguishing roller 8 is positioned in front of the active conveying roller 13, and the cleaning roller 6 is positioned on the vertical line connecting the centers of the primary smoke-extinguishing roller 7 and the secondary smoke-extinguishing roller 8. The active conveying roller 13 rotates in the opposite direction to the primary smoke-extinguishing roller 7 and the secondary smoke-extinguishing roller 8.

[0064] The primary smoke-extinguishing roller 7 and the secondary smoke-extinguishing roller 8 work in sequence with the active conveyor roller 13 to crush the cigarette butt.

[0065] In this embodiment, the surface of the primary smoke-extinguishing roller 7 is provided with four primary ribs 7.1, and the secondary smoke-extinguishing roller 8 is provided with four secondary ribs 8.1. The primary ribs 7.1 and the secondary ribs 8.1 cooperate with the active conveying roller 13 in sequence to crush the cigarette butt.

[0066] The primary rib 7.1 extends from one end of the primary smoke-extinguishing roller 7 to the other and is spirally arranged around the roller axis; the secondary rib 8.1 extends from one end of the secondary smoke-extinguishing roller 8 to the other and is parallel to the roller axis (in other embodiments, the primary rib 7.1 may also extend from one end of the primary smoke-extinguishing roller 7 to the other and be parallel to the roller axis; in other embodiments, the secondary rib 8.1 may also be omitted, but the corresponding effects of the two arrangements of the primary and secondary ribs in other embodiments are inferior to the arrangement in this embodiment). See attached figure. Figure 4 During the rotation of the primary smoke-extinguishing roller 7, the gap between the primary rib 7.1 and the active conveying roller 13 changes, making it easier to roll up the cigarette butt and preventing the cigarette butt from not being rolled up or from spinning.

[0067] Because the cigarette butt is thinned by the rolling of the primary rib 7.1 and the active conveyor roller 13, the distance from the primary rib 7.1 to the active conveyor roller 13 is greater than the distance from the secondary rib 8.1 to the active conveyor roller 13.

[0068] In this embodiment, the primary extinguishing roller 7, the secondary extinguishing roller 8, and the cleaning roller 6 are respectively supported on the supports 11 on both sides of the ashtray. The roller shaft of the cleaning roller 6 can be slidably arranged relative to the support 11. Preferably, a bushing 9 that cooperates with the support 11 can also be provided on the journal 6.1 of the cleaning roller 6 to reduce the wear between the journal 6.1 and the support 11.

[0069] In this embodiment, the reciprocating structure includes a ball head, a rotary wheel 5, and a spring 10. The cleaning roller 6 has a ball head at one end of its journal 6.1 and a spring 10 on the other end of its journal 6.1. The rotary wheel 5 is rotatably mounted and has a concave-convex part on its end face arranged around its own axis. Under the action of the spring 10, the ball head and the concave-convex part are kept in contact. The ball head is hemispherical and fixed to the end of the journal 6.1, making the fit between the journal 6.1 and the concave-convex part smoother. When the rotary wheel 5 rotates, the cleaning roller 6 is driven to reciprocate along its own axis through the fit between the concave-convex part and the ball head.

[0070] In some other embodiments, the reciprocating structure is not limited to the structure mainly composed of the ball head, the rotating wheel 5 and the spring 10 described above. A lever can also be connected to one end of the cleaning roller 6. The lever cooperates with the shift fork. The shift fork is driven by a linear module or an electric push rod to perform reciprocating translational motion along its own axis.

[0071] In this embodiment, the drive unit 1 uses a motor and drives the active conveyor roller 13, the primary extinguishing roller 7, the secondary extinguishing roller 8, and the return wheel to rotate synchronously via a gear transmission unit. The use of a motor and gear transmission unit to drive the active conveyor roller 13, the primary extinguishing roller 7, the secondary extinguishing roller 8, and the return wheel to rotate synchronously allows for a more compact structure of the extinguishing mechanism and better control of the overall volume of the ashtray. Specifically, the end of the primary extinguishing roller 7 is connected to a first transmission gear 3, the end of the secondary extinguishing roller 8 is connected to a second transmission gear 4, the end of the active conveying roller 13 is connected to a third transmission gear 14, and the output end of the motor is connected to a main transmission gear 2. The main transmission gear 2, the third transmission gear 14, the first transmission gear 3, the second transmission gear 4, and the rotary wheel 5 (the rotary wheel 5 is based on a gear structure with added concave and convex portions at its end) mesh and transmit power. Specifically, the main transmission gear 2 meshes with the third transmission gear 14, the third transmission gear 14 simultaneously meshes with the first transmission gear 3 and the second transmission gear 4, and the second transmission gear 4 also meshes with the rotary wheel 5. The cleaning roller 6 rotates under the drive of the primary extinguishing roller 7 and the secondary extinguishing roller 8, and the bristles gently peel away the ash adhering to the primary extinguishing roller 7 and the secondary extinguishing roller 8, reducing the probability of ash splattering.

[0072] An ashtray includes the aforementioned extinguishing mechanism. Specifically, the ashtray has a cigarette butt dispensing chamber with an open bottom. A cigarette butt conveying structure is located at the bottom of the cigarette butt dispensing chamber, and the conveyor belt 12 of the cigarette butt conveying structure encloses the open opening at the bottom of the cigarette butt dispensing chamber.
