Detailed Description

In order to facilitate an understanding of the present application, a more complete description of the present application will now be provided with reference to the relevant figures. Preferred embodiments of the present application are shown in the accompanying drawings. This application may, however, be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

In the related art, fly ash during smoking is difficult to collect well in the ashtray.

Based on this, the present application intends to provide a solution to the above technical problem, the details of which will be explained in the following embodiments.

Examples:

the present embodiment provides an ashtray, see fig. 1 to 11, which includes, but is not limited to, a cylinder 1, a fairing 2, an ash blocking portion 3, and a negative pressure unit for forming a negative pressure. The cylinder 1 of the present embodiment may be made of any nonflammable material, and is used for storing objects such as soot, cigarette ends, etc., as in the cylinder 1 of the conventional ashtray.

It can be understood that the fairing 2 is made of a nonflammable material, and the fairing 2 of this embodiment is disposed corresponding to the cylinder 1. The cowling 2 of the present embodiment is disposed in the cylinder 1 and cooperates with the cylinder 1 to form the air inlet 21 and the ash discharge port 22, wherein the air inlet 21 is disposed away from the bottom of the cylinder 1 and the ash discharge port 22 is disposed close to the bottom of the cylinder 1, and it should be understood that the foregoing "away" and "close" merely describe the relative positional relationship between the air inlet 21 and the ash discharge port 22, and do not limit the specific distance between the two and the bottom of the cylinder 1. Between the air inlet 21 and the ash discharge opening 22, an air outlet 23 is further included, and when the ashtray sucks ash, the negative pressure unit makes the area 4 between the fairing 2 and the cylinder 1 form negative pressure, the air outlet 23 exhausts the air, and the air inlet 21 and the ash discharge opening 22 suck the air into the area 4 between the fairing 2 and the cylinder 1 at the same time. In the present embodiment, the opening area of the air inlet is larger than the opening area of the ash discharge port so that the air flow at the air inlet is larger than the air flow at the ash discharge port, which can make the air inlet have relatively small air intake resistance, and the ash discharge port has relatively large air intake resistance, thereby forming the air intake negative pressure concentrated in the edge area of the ashtray above the ashtray. That is, by distributing the air flow, the suction force at the air inlet is made larger, and the soot can be effectively sucked.

In the present embodiment, the air inlet 21 is directed to the outside of the ashtray, which serves to directly suck air and soot from the outside. In practice, the position of the air inlet 21 may be located at the very top of the ashtray, so as to better suck in the air and soot in the environment; in some embodiments it is equally feasible that the air inlet 21 is arranged slightly below the top end of the ashtray.

The ash discharge port 22 is located closer to the bottom of the ashtray than the air inlet 21, it being understood that when the air outlet 23 is exhausted to the outside, a negative pressure is created in the area 4 between the fairing 2 and the cylinder 1, and that also outside air can enter the area 4 between the fairing 2 and the cylinder 1 from the ash discharge port 22.

In practical application, the air intake negative pressure at the ash discharge port 22 can be designed according to the requirement, and different air intake negative pressures can be formed at the ash discharge port 22 in the process of collecting ash through controlling the working power of the negative pressure unit or adjusting the position, the size and the like of the ash discharge port 22. In this embodiment, the negative pressure of the air intake at the ash discharge port 22 can be controlled to a small extent, so that the solid matters such as the collected ash can easily fall to the bottom of the cylinder 1 directly through the ash discharge port 22. In some implementations, the negative pressure of the intake air formed at the ash discharge port 22 may be configured to be large, and the ash discharge port 22 may be configured to form an airflow opposite to that of the intake port 21, and in some implementations, may cause the inhaled soot to temporarily stagnate in the region 4 between the cowling 2 and the cylinder 1. The large mass of soot is pushed by the airflow to repeatedly collide with the fairing 2 or the cylinder 1, so that the soot is easily broken into smaller soot particles, and the smaller soot particles can fall into the cylinder 1 through the soot discharge port 22 more smoothly. When the function of collecting the soot is turned off (i.e., the negative pressure unit stops working, the exhaust port 23 will not exhaust the outside anymore), or the airflow is actively controlled to be small, the airflow is not formed at the soot discharge port 22 or insufficient to push the soot to stay in the area 4 between the cowling 2 and the cylinder 1, and solid matters such as soot fall from the soot discharge port 22 to the bottom of the cylinder 1 under the action of gravity. In practical application, the exhaust of the exhaust port 23 may be configured to be intermittently stopped for a certain period of time after the operation, so as to timely exhaust the soot retained in the area 4 between the fairing 2 and the cylinder 1.

In fact, since the ash discharge port 22 is formed by the cooperation of the cowling 2 and the cylinder 1, the ash discharge port 22 can be directly located inside the cylinder 1, ensuring that the soot can fall into the cylinder 1.

The soot blocking portion 3 is provided corresponding to the exhaust port 23 for blocking the exhaust of soot from the exhaust port 23. The soot blocking part 3 prevents soot from entering the exhaust passage and also prevents soot from entering the air extraction equipment, so that the soot only stays in the area 4 between the fairing 2 and the cylinder body 1 or falls to the bottom of the cylinder body 1, the soot is easy to clean, and the exhaust passage is easy to keep clear. The soot barrier 3 may be provided in the area 4 provided between the fairing 2 and the cylinder 1 or in other locations, and in some embodiments the soot barrier 3 is removable for replacement or cleaning after having adsorbed soot thereon. The soot blocking portion 3 may be a structure including, but not limited to, filter cotton, a filter screen, etc. capable of blocking dust particles such as soot, etc., and the embodiment is not limited to a specific structure, and in practical application, a nonflammable material may be selected to avoid being damaged by incompletely burned soot. In some implementations, the soot barrier 3 may also be configured as a filtering member capable of adsorbing and eliminating harmful gases, and may function as air filtering to some extent.

In the related art, the negative pressure formed in the ashtray is small, and the adsorption force to the ash is insufficient. The ashtray of the embodiment is provided with the fairing 2 and the cylinder body 1 to form the air inlet 21 and the ash discharge opening 22, the opening area of the air inlet 21 is larger than that of the ash discharge opening 22, and larger negative pressure can be formed at the air inlet 21, so that flying ash can be sucked more effectively; the ash can finally fall into the cylinder body 1, the inhaled ash can not enter the exhaust channel, the ash still can be collected through the cylinder body 1, the condition that the ash is accumulated in all parts of the ash tray can not occur, and the ash tray is easy to clean.

In some embodiments, the fairing 2 is a detachable structure, so that soot in the cylinder body 1 is easy to clean and to treat, and when the fairing 2 is not installed, the ashtray also has the capability of sucking external air under negative pressure, and the effects of purifying air and reducing smoke can be achieved in some embodiments.

In some embodiments, the distance between the exhaust port 23 and the intake port 21 is smaller than the distance between the exhaust port 23 and the ash port 22, i.e., the exhaust port 23 is disposed closer to the intake port 21. In some implementation processes, the airflow of the air inlet 21 is larger, and the airflow of the ash outlet 22 is smaller, so that better airflow distribution is formed, and the effect of sucking ash is ensured.

For better intake of soot, in practice the intake openings 21 may be distributed along the circumference of the ashtray. Illustratively, the air inlet 21 may be provided in a plurality and uniformly distributed to achieve multi-directional soot inhalation, and the shape of the air inlet 21 may include various shapes such as a circle, a rectangle, a bar, and the like. The air inlet 21 may be provided entirely around the ashtray in order to maximize the area around the ashtray. In some embodiments, the upper edge of the fairing 2 cooperates with the top of the sidewall of the cylinder 1 to form an air inlet 21 around the cylinder 1, and the lower edge of the fairing 2 cooperates with the sidewall of the cylinder 1 to form an ash discharge 22 around the cylinder 1. The circle of the present embodiment is formed in a circular shape in a plan view of the air inlet 21 and the ash discharge port 22, and is provided along the circumference of the cylinder 1, for example, a circular cylinder 1. Of course, the contour shape of the cylinder 1 and the fairing 2 is not limited in this embodiment, in other examples, the cylinder 1 may be square, rectangular, oval or any other shape, and the upper edge and the lower edge of the fairing 2 are matched with the shape of the cylinder 1, so that the widths of the air inlet 21 and the ash discharge opening 22 are consistent or substantially consistent, and the air flow is ensured to be uniform all around. It should be noted that the "upper" described in the present embodiment is a direction away from the bottom of the cylinder 1, and the "lower" is a direction toward the bottom of the cylinder 1; similarly, "above" means farther from the bottom of the cylinder 1 and "below" means closer to the bottom of the cylinder 1.

In some embodiments, the fairing 2 is a hollow structure, the hollow area of the fairing is communicated with the interior of the cylinder body 1, the cylinder body 1 is communicated with the outside in an unobstructed manner through the hollow area, the interior of the cylinder body 1 is unobstructed in the hollow area of the fairing 2, the cylinder body 1 is ensured to have a larger accommodating space, and the input of large solid garbage such as cigarette ends is not blocked. The flow direction and distribution of the air flow in the ashtray structure illustrated in fig. 4 is illustrated in fig. 6 by arrows, wherein the size of the arrows can correspond to the relative size of the air flow. When the fairing 2 is of a hollow structure, large substances such as a cigarette head can be conveniently put into the ashtray, and air in the external environment can also directly enter the cylinder body 1 through the hollow area of the fairing 2. And since the ash discharge port 22 is also communicated with the interior of the cylinder 1, when the exhaust port 23 is externally exhausted, the ash discharge port 22 sucks the gas in the interior of the cylinder 1 into the region 4 between the cowling and the cylinder. In this embodiment, the opening area of the hollow area is larger than the opening area of the air inlet 21, which will make the inside of the cylinder 1 form a smaller negative pressure, and the outside air flows to the inside of the cylinder 1 through the hollow area of the fairing 2, so as to avoid the smoke generated by the smoke ash and the cigarette end at the bottom of the cylinder 1 from escaping to the outside, and protect the outside environment in some implementation processes. It can be seen that the opening area of the cylinder 1 is partitioned by the cowling 2; under the same exhaust flow, the peripheral air inlets 21 form a larger suction force to collect the soot, and a smaller suction force is formed in the central area to inhibit the smoke from drifting out, so that both the collection of the soot and the inhibition of the smoke can be achieved. Therefore, the ashtray can work based on smaller exhaust flow, and compared with the method of directly forming negative pressure in the ashtray, the ashtray is excellent in performance in noise, power consumption and the like.

As described above, the main purpose of the fairing 2 is to distribute the airflow, so that in practical applications, the shape of the fairing 2 can be flexibly designed. In some embodiments, the fairing 2 is large in size at both ends, small in size in the middle, and the outer wall includes a concave arcuate surface. For example, referring to fig. 3 to 6, the openings on both sides of the cowling 2 are large, while the middle portion is narrowed, the middle portion is formed in a concave shape as a whole, and the surface thereof includes an arc shape. This enables the air flow entering from the air inlet 21 to flow along the arcuate surface, after forming an arcuate flow, towards the air outlet 23 of the side wall of the cylinder 1, and the air flow entering at the ash outlet 22 has a degree of collision with the air flow entering at the air inlet 21, which causes the area 4 between the fairing 2 and the cylinder 1 to be prone to forming a vortex in which the ash repeatedly collides with the cylinder 1 or fairing 2, with the formation of smaller ash particles being more prone to being able to fall smoothly into the cylinder 1 through the ash outlet 22.

The fairing 2 may be mounted in any manner without affecting the air flow, for example the fairing 2 may be placed directly into the cylinder 1 by means of a bracket 24 projecting towards the cylinder 1, the bracket 24 supporting the fairing 2 to the desired height. Referring to fig. 10, in some embodiments, the fairing 2 includes an outwardly extending bracket 24, the bracket 24 extending such that the maximum dimension of the fairing 2 is larger than the opening of the cylinder 1, whereby the bracket 24 can ride on top of the cylinder 1 to support the fairing 2 in the region of the top of the cylinder 1. In this embodiment, 4 brackets 24 are uniformly distributed along a circle of the fairing 2, and the height of the fairing 2 after installation can be controlled by controlling the installation position of the brackets 24. In other implementations, the number and specific shape of the brackets 24 may be set according to actual needs, and the present embodiment is not limited. The fairing 2 may further include a limiting portion 25 extending outwards, where the limiting portion 25 is configured to cooperate with the inner wall of the cylinder 1 to locate the fairing 2, and the limiting portion 25 may be disposed at a position below the fairing 2 in cooperation with the inner wall of the cylinder 1. For example, in some implementations, the limiter 25 may be disposed at a lower edge of the fairing 2. The size of the limiting part 25 can be set according to the sizes of the fairing 2 and the interior of the cylinder body 1, and when the fairing 2 is placed in the cylinder body 1, the limiting part 25 is used for assisting in limiting the position of the fairing 2, so that the fairing 2 is accurately and stably positioned at a required position, and the airflow rectifying effect is better realized; in some implementations, the limiting portion 25 can also have an auxiliary supporting effect. In this embodiment, the limiting portions 25 are also configured to be 4 evenly distributed along the fairing 2, and in other implementation processes, the number and specific shape of the brackets 24 may be set according to actual requirements, which is not limited in this embodiment. The support 24 of this embodiment makes the radome fairing 2 set up in the unsettled place in cylinder body 1, does not directly support in the bottom of cylinder body 1, has avoided objects such as cigarette ash, cigarette end of direct contact bottom, be difficult for being polluted, also can not take out cigarette ash when dismantling.

To enable better intake of the fly ash, in some embodiments the air inlet 21 is positioned at the top of the ashtray and is inclined outwards to form an intake air flow with a certain inclination. That is, the air inlet 21 is located at the highest position of the ashtray, and the air inlet 21 may be disposed to be flush with the height of the cylinder 1 or may even be higher than the height of the cylinder 1, taking an embodiment in which the air inlet 21 is formed by the cooperation of the cowling 2 and the side wall of the cylinder 1 as an example. Illustratively, after the fairing 2 is installed, the upper edge of the fairing is slightly higher than the top of the cylinder 1, so that the air inlet 21 is positioned at the top of the ashtray, and simultaneously, an outward inclination is formed, so that negative pressure can be formed in a larger area around the ashtray to absorb surrounding soot in a larger area. As shown in fig. 6, in some embodiments, the soot blocking portion may extend to the vicinity of the air inlet 21, and form an integrally inclined air flow inlet in cooperation with the cowling 2, so as to achieve a better flow guiding effect; in other examples, this may be achieved in other ways, for example the structure of the housing 11 may be configured directly so that it can form an integrally inclined airflow inlet with the fairing 2.

In some embodiments of the present embodiment, the cylinder body 1 of the ashtray includes an inner cylinder 12 and a housing 11, and the housing 11 is sleeved outside the inner cylinder 12. The outer shell 11 is larger than the inner cylinder 12 in size and has a certain clearance with the inner cylinder 12, the clearance can be used as an air flow channel 5, an exhaust port 23 is communicated with the air flow channel 5, and when the exhaust is needed, the air in the area 4 between the fairing 2 and the cylinder body 1 enters the air flow channel 5 through the exhaust port 23 and is exhausted along the air flow channel 5. In some examples, the inner cylinder 12 and the outer shell 11 can be freely detached, so that the inner cylinder 12 can be conveniently and independently removed for cleaning; in other examples, the inner jar 12 may be fixed relative to the outer casing 11, and the soot and the tobacco tip therein may be poured out and cleaned by removing the fairing 2 or the like.

As shown in fig. 3 to 6, in some embodiments, the top of the inner cylinder 12 is lower than the top of the outer shell 11, the gap between the inner cylinder 12 and the outer shell 11 forms the airflow passage 5, when the fairing 2 is placed into the cylinder 1, it cooperates with the inner walls of the inner cylinder 12 and the outer shell 11 to form the air intake 21 and the ash discharge 22, and the gap existing between the top of the inner cylinder 12 and the inner wall of the outer shell 11 forms the air discharge 23 that communicates the area 4 between the fairing 2 and the cylinder 1 with the airflow passage 5.

It will be appreciated that the ashtray of the present embodiment comprises a negative pressure unit that is capable of generating a negative pressure. The negative pressure unit may be an independent air extracting device such as an air pump, or may be a driving device capable of driving, for example, the fan blade 121 to move and drive the air to flow.

In some embodiments, the inner cylinder 12 may include a fan blade 121, the fan blade 121 being disposed on an outer wall of the inner cylinder 12 and within the airflow channel 5. In addition, the negative pressure unit includes a rotating device 122, and the inner cylinder 12 is also connected to the rotating device 122, and the rotating device 122 includes, but is not limited to, a rotating motor. The rotating device 122 is used for driving the inner cylinder 12 to rotate, and when the inner cylinder 12 rotates, the fan blades 121 are driven to move to form air flow and are discharged to the outside along the air flow channel 5, so that the area 4 between the fairing 2 and the cylinder body 1 forms negative pressure. Illustratively, the rotating means 122 may be fixed to the housing 11, and the center of the bottom of the inner cylinder 12 is connected to the rotating means 122 when the inner cylinder 12 is mounted in the housing 11.

The vanes 121 of the inner cylinder 12 may be provided in any pattern, such as in the example of fig. 7, with the vanes 121 of the inner cylinder 12 being configured as a plurality of circumferentially disposed vanes that are inclined at an angle to create an air flow during rotation with the inner cylinder 12. Each blade may be flat and form an airflow when the inner cylinder 12 rotates by being inclined, and in some examples, the fan blade 121 may be a blade having a certain curvature, and its specific shape may be set as required. In other examples, fan blade 121 may take other forms. In some embodiments, the fan blade 121 of the inner cylinder 12 may also be one or more blades that are continuously disposed at least one revolution around the outer wall of the inner cylinder 12. In practice, the fan blades 121 may be sized to match the size of the airflow channel 5, i.e. as close as possible to the inner wall of the housing 11 without affecting the rotation of the inner cylinder 12, in order to stabilize and generate a strong airflow.

In the above example, by controlling the rotation of the inner tub 12 itself to form an air flow, no external negative pressure device is required to be connected, so that the integrity of the ashtray is better. In addition, the rotating inner jar 12 can rotate relative to the outer shell 11 and the fairing 2, namely, the fairing 2 and the outer shell 11 are fixed, when the ash with large lump falls to the ash discharge port 22 formed by the matching of the side wall of the inner jar 12 and the lower edge of the fairing 2, the ash with the size larger than the ash discharge port 22 can be stirred by the matching of the fairing 2 and the rotating inner jar 12, so that the ash can finally smoothly fall to the bottom of the inner jar 12 through the ash discharge port 22; in addition, if the fairing 2 is provided with the limiting part 25, the limiting part 25 can collide with the soot, so that the effect of stirring the soot is further improved. On the other hand, the fairing 2 and the housing 11 remain relatively stationary, and the stop 25 may also assist in limiting the position of the inner cylinder 12 during some implementations to maintain a stable position of the inner cylinder 12 during rotation.

In some embodiments, the shell 11 of the ashtray further comprises an ash blocking part mounting part 112 arranged on the inner wall of the shell 11, the ash blocking part mounting part 112 is arranged at a position higher than the top of the inner ashtray 12, and the ash blocking part 3 is arranged on the shell 11 through the ash blocking part mounting part 112 and extends to cover the exhaust port 23. As in the example of fig. 8, the soot barrier mounting portion 112 is a round of protrusions, and the soot barrier 3 may be a full round of filter mesh configured to include a shape matching the protrusions of the soot barrier mounting portion 112 to achieve accurate mounting. In this example, the soot barrier 3 extends downward until it covers the exhaust port 23. To ensure proper rotation of the inner cylinder 12, the soot blocking portion 3 may not contact the inner cylinder 12, forming a small gap with the inner cylinder 12, or the soot blocking portion 3 may be made of a softer material so as not to affect its rotation even if it slightly contacts the inner cylinder 12. The ash blocking part mounting part 112 is arranged at the position, higher than the inner jar 12, of the inner wall of the outer shell 11, so that the ash blocking part 3 is exposed in the cylinder body 1, namely, the ash blocking part is not clamped between the outer shell 11 and the inner jar 12, and the ash blocking part 3 can be conveniently and directly detached, replaced or cleaned without completely disassembling the cylinder body 1.

As an example, the support 24 of the fairing 2 may rest on the casing 11, achieving a relative rest with respect to the casing 11. In some examples, for example, as shown in fig. 9, the soot blocking portion 3 is provided with a notch 31, and the support 24 of the fairing 2 may also be mounted on the soot blocking portion 3, where the notch 31 on the soot blocking portion 3 accommodates the support 24 of the fairing 2, so that the position of the support 24 of the fairing 2 can be ensured to be accurate to some extent. In practical applications, the manner of mounting the cowling 2 is not limited to the above examples.

In some embodiments, see for example fig. 3 to 6, the gas flow channel 5 comprises at least a space between the outer wall of the inner cylinder 12 and the inner wall of the housing 11, and the gas flow channel 5 can be communicated with the outside by opening a first through hole 111 in the side wall of the housing 11, so as to discharge the gas into the external environment. The inner wall of the outer shell 11 can be circumferentially provided with a blocking rib 113, and the blocking rib 113 is lower than the first through hole 111 but higher than the bottom of the inner cylinder 12; the blocking rib 113 is matched to the size of the inner cylinder 12 and defines the air flow passage 5 together with the side wall of the outer case 11 and the side wall of the inner cylinder 12. The separation area between the inner cylinder 12 and the outer shell 11 is separated by the separation rib 113, so that a cavity at the lower part of the inner cylinder 12 and the outer shell 11 is separated from the air flow channel 5, and an air flow field is simplified; on the other hand, the blocking rib 113 can also limit the installation position of the inner cylinder 12, and ensure the position stability of the inner cylinder 12.

Referring to fig. 11, another more specific ashtray construction is illustrated. In this example, the top of the inner cylinder 12 may be flush or nearly flush with the outer shell 11, and a second through hole 123 may be formed in the sidewall of the inner cylinder 12 as the exhaust port 23. The form of the second through hole 123 may be arbitrary, for example, circular, square, triangular, or other arbitrary shape; in some examples, the second through hole 123 may also be an elongated slit or the like. It should be noted that, in the present embodiment, the description of "first" and "second" in the first through hole 111 and the second through hole 123 is only for the purpose of describing the distinction between the through holes at different positions, and is not meant to be limited otherwise.

In this example, the soot blocking portion 3 may be disposed corresponding to the position of the second through hole 123, and the soot blocking portion 3 may be disposed inside the inner cylinder 12 or may be disposed between the inner cylinder 12 and the outer case 11 as in the example of fig. 11. The number of the second through holes 123 as the exhaust ports 23 may be plural, and correspondingly, the number of the soot blocking portions 3 may be plural, which are arranged in one-to-one correspondence with the exhaust ports 23, or one soot blocking portion 3 may be provided corresponding to plural exhaust ports 23, for example, the soot blocking portion 3 is provided in a full circle so as to cover all the exhaust ports 23 at the same time.

In the above example, the connecting portion 114 for connecting the air extracting device to exhaust the air is further disposed on the housing 11, and the connecting portion 114 may be an opening disposed at the bottom of the housing 11, through which the air is exhausted, and the air extracting device is connected to the opening, so as to achieve air extraction and exhaust of the air in the cylinder. It should be noted that the air extraction device may be directly connected to the housing 11 or may be indirectly connected through the other air flow channel 5, i.e. its connection to the housing 11 means that the air flow is able to communicate. In some examples, the connection 114 may also be formed in a shape that facilitates docking, such as an external protrusion for connection to a pipe. The installation position of the connection portion 114 is not limited to the bottom of the housing 11, and may be provided on a side wall of the housing 11, for example.

In the above example, the ashtray may further include a base, in which the air extracting device as the negative pressure unit is disposed, and the connection part 114 of the case 11 is abutted with the air extracting device of the base when the case is disposed on the base. The air extractor is integrated through the base, the integrity is also better, the air extractor can be separated from the cylinder body 1, the uncharged cylinder body 1, the fairing 2 and the like can be independently taken down for cleaning, and in addition, the shell 11 of the base can also form packaging protection for the air extractor and the circuit thereof, so that the quality of products is improved.

Referring to fig. 12, the flow direction and distribution of the air flow in the ashtray structure illustrated in fig. 11 are illustrated with arrows drawn in a hollow form, wherein the size of the arrows can correspond to the relative size of the air flow, and fig. 12 illustrates only the air flow of the left portion of the illustration, and it is understood that the air flow of the remaining portion is the same. In the above example, when the inhalation of soot is started, the outside air mainly enters the region 4 between the cowling 2 and the cylinder 1 through the air inlet 21, and a small portion of the air also directly enters the inside of the cylinder 1 through the hollow region of the cowling 2 and enters the region 4 between the cowling 2 and the cylinder 1 from the soot discharge port 22. The gas in the region 4 between the cowling 2 and the cylinder 1 enters the gas flow channel 5 through the exhaust port 23, and the soot therein is blocked by the soot blocking portion 3 to remain in the region 4 between the cowling 2 and the cylinder 1. The air is finally pumped out of the ashtray by the air pumping device along the air flow channel 5 through the connecting part 114, and in practical application, a filter layer and other structures capable of purifying the air can be arranged in the air pumping device, so that the air finally exhausted to the external environment is purified. When the suction device stops suction, the air flow in the ashtray is restored to a natural state, and the soot retained in the area 4 between the fairing 2 and the cylinder 1 falls to the bottom of the cylinder 1 through the soot discharge opening 22.

It is to be understood that the invention is not limited in its application to the examples described above, but is capable of modification and variation in light of the above teachings by those skilled in the art, and that all such modifications and variations are intended to be included within the scope of the appended claims.
