[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present utility model. In addition, the terms "first", "second", "third", "fourth", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0040] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] See also Figures 1 to 10 The embodiment of the utility model discloses a cleaning mechanism of a smoking device, comprising a shell 1 and a flue 11 formed in the shell 1, a receiving groove 12 for receiving a cleaning ejector pin 5 is provided at the bottom of the shell 1, and a double-layer collecting pipe 2 is provided in the flue 11;

[0042] Specifically, the smoke duct 11 of the smoking device can provide a position for accommodating cigarettes, and after the cigarette is inserted into the smoke duct, the cigarette butt is suspended above the double-layer collecting tube 2, and the ash produced by the burning cigarette can be collected through the double-layer collecting tube 2 to reduce the pollution caused by the ash.

[0043] The double-layer collecting tube 2 comprises an outer collecting tube 3 detachably installed in the flue 11 and an inner collecting tube 4 arranged in the outer collecting tube 3 by interference fit, the outer collecting tube 3 is provided with an outer vent hole 31 at the bottom for connecting the double-layer collecting tube 2 to the outside air, the inner collecting tube 4 is provided with an inner vent hole 41 on the side wall for connecting the double-layer collecting tube 2 to the flue 11, and the bottom of the inner collecting tube 4 is a ash collecting bin 42 formed by a sealing structure;

[0044] Specifically, the double-layer collecting tube 2 as the outer collecting tube 3 abutting the inner wall of the flue 11 adopts an interference fit installation method to prevent the ash produced by the burning cigarette from falling along the gap between the inner wall of the flue 11 and the outer collecting tube 3, avoiding the ash from being retained in the gap or even being discharged from the smoking device along the gap, thereby reducing the pollution of the smoking device and the external environment by the ash.

[0045] Furthermore, after the cigarette is inserted into the flue, the cigarette butt is located directly above the ash collection bin 42, and the ash collection bin 42 can completely collect the ash that gradually falls from the burning cigarette butt. It is easy for technicians in this field to know that in order to ensure that the ash can be completely collected in the smoking device, the design of the flue 11 and the collection functional structure is often relatively closed, and the burning of cigarettes requires circulating air to provide oxygen to continue. Therefore, when using a closed method to solve the problem of ash collection, it is also necessary to solve the problem of air circulation in the flue 11.

[0046] Furthermore, the outer collecting tube 3 arranged at the bottom of the flue 11 is in contact with the outside world, and the outside air is connected to the double-layer collecting tube 2 through the outer vent hole 31 arranged at the bottom of the outer collecting tube 3. After the outside air enters the gap between the outer collecting tube 3 and the inner collecting tube 4, the gap between the outer collecting tube 3 and the inner collecting tube 4 is connected to the ash collecting bin 42 of the inner collecting tube 4 through the inner vent hole 41 arranged on the side wall of the inner collecting tube 4. At this point, the double-layer collecting tube 2 can solve the problem of ash collection and pollution prevention while establishing the connection between the flue 11 and the outside air, so that the air flowing to the flue 11 can provide oxygen for cigarette combustion, while ensuring that the ash produced in the smoking device only remains in the flue 11.

[0047] The cleaning ejector pin 5 is used to lift up the inner collecting tube 4 in the double-layer collecting tube 2 through the outer vent hole 31 , and to clean the ash collecting bin 42 through the cleaning ejector pin 5 .

[0048] Specifically, in addition to the double-layer collection tube 2 for collecting cigarette ash, the smoking device is also equipped with a cleaning ejector 5 for cleaning the cigarette ash. The working principle of the cleaning mechanism in the present application is: when the smoking device is working, the double-layer collection tube 2 is used to collect the ashes dropped by the burning cigarette. After the smoking device is used up, the double-layer collection tube 2 is pulled out from the bottom of the flue 11, and the double-layer collection tube 2 is inverted to shake all the ashes in the ash collection bin 42 into the trash can. For the ashes attached to the tube wall in the double-layer collection tube 2, the cleaning ejector 5 can be taken out from the storage groove 12, and the cleaning ejector 5 can be extended into the ash collection bin 42 of the inner collection tube 4 for cleaning, and the stubborn dirt that cannot be cleaned by shaking is thoroughly cleaned. The user does not need to carry additional cleaning tools, and can clean the ashes in the smoking device at any time. Solving the problem of regular cleaning of the ashes in the smoking device can effectively improve the user experience.

[0049] Furthermore, in cases where the pollution is more serious, a cleaning pin 5 can be used to pass through the outer ventilation hole 31 to lift up the inner collecting tube 4, thereby separating the outer collecting tube 3 and the inner collecting tube 4 of the double-layer collecting tube 2. The cleaning pin 5 can be inserted into the outer collecting tube 3 and the inner collecting tube 4 for cleaning, thereby increasing the user's freedom to clean the smoking device, solving the ash cleaning problem existing in different smoking devices, and improving the user's experience.

[0050] As a preferred embodiment, an annular groove 51 for conveniently taking the cleaning ejector 5 is provided at the end of the cleaning ejector 5 .

[0051] Specifically, when the user takes the cleaning ejector 5 out of the storage groove 12, the user can hold the position of the annular groove 51 and use the groove wall of the annular groove 51 as a force point to exert force, thereby easily taking the cleaning ejector 5 out of the storage groove 12. Especially when the cleaning ejector 5 is stuck and cannot be taken out, the design of the annular groove 51 can help the user to easily take it out and clean the smoking device.

[0052] As a preferred embodiment, the opening of the receiving groove 12 is interference-fitted with the cleaning ejector pin 5 so that the cleaning ejector pin 5 is confined in the receiving groove 12 .

[0053] Specifically, the interference fit can effectively prevent the cleaning ejector pin 5 from falling out of the storage slot 12 and causing the cleaning ejector pin 5 to be lost, and the user does not need to exert excessive force to pull out the cleaning ejector pin 5 when taking the cleaning ejector pin 5, thereby improving the user's experience.

[0054] As a preferred embodiment, a pull ring 32 for taking out the double-layer collecting tube 2 from the flue 11 is further provided at the bottom of the outer collecting tube 3 .

[0055] As a preferred implementation, the cross-sectional diameter of the outer collecting tube 3 is greater than the cross-sectional diameter of the inner collecting tube 4 .

[0056] As a preferred implementation, the cross-sectional diameter of the flue 11 is not less than the cross-sectional diameter of the outer collecting pipe 3 .

[0057] As a preferred embodiment, the arrangement of the outer vent holes 31 and the inner vent holes 41 includes uniform arrangement, array arrangement and irregular arrangement.

[0058] It should be noted that the arrangement of the ventilation holes in the present application includes but is not limited to uniform arrangement, array arrangement and irregular arrangement. As long as the air flow rate to ensure the burning of the cigarette can be achieved, the number, shape and arrangement of the ventilation holes that can achieve the above-mentioned purpose of ensuring the burning of the cigarette are acceptable.

[0059] As a preferred embodiment, a protrusion 52 for passing through the outer vent hole 31 is provided at the top end of the cleaning ejector pin 5 , and a cross-sectional diameter of the protrusion 52 is smaller than the aperture of the outer vent hole 31 .

[0060] As a preferred embodiment, a force-bearing plane 53 for abutting against the bottom of the outer collecting tube 3 is provided on the top of the protrusion 52 .

[0061] As a preferred embodiment, the shape of the protrusion 52 includes conical, polygonal, polyhedral and irregular shapes.

[0062] It should be noted that the shape of the protrusions in the present application includes but is not limited to conical, polygonal, polyhedral and irregular shapes, as long as the purpose of cleaning the ash collection bin 42 can be achieved.

[0063] The utility model realizes the collection of ashes from the smoking device through the double-layer collecting tube. At the same time, the double-layer collecting tube can ensure the connection between the flue and the outside air, and does not affect the combustion of the cigarette while collecting the ashes. The shell is built with a cleaning ejector which cooperates with the double-layer collecting tube to clean the ashes. The user can clean the smoking device at any time without carrying additional cleaning tools. While ensuring the hygienic use of the smoking device, the user experience is improved.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
