Description

Technical Field

[0001] The utility model relates to the technical field of smoking devices, in particular to an ashtray collection mechanism and a smoking device. Background Art

[0002] During the smoking process, a large amount of cigarette ash is generated by the burning of cigarettes. Especially when smoking indoors or in a car, it will affect the hygiene of the ground, table, clothes and the interior of the car, and is likely to cause indoor environmental pollution. Therefore, a smoking device that can collect cigarette ash is proposed to retain all the cigarette ash generated by the burning of cigarettes in the smoking device to avoid the scattered cigarette ash from polluting the environment.

[0003] The existing smoking devices concentrate the functions of cigarette burning and ash collection on the flue design. However, the burning of cigarettes requires a continuous flow of oxygen-containing air in the flue. Otherwise, the cigarettes cannot continue to burn in the case of poor air circulation, which will affect the smoking experience of smokers. In order to achieve the purpose of air circulation in the flue, the design of ventilation holes also has the problem that cigarette ash or tar is discharged outside the smoking device along the ventilation holes, which will also cause pollution.

[0004] Therefore, there is an urgent need for an ashtray collection mechanism that can continuously ventilate the flue of the smoking device while having strong sealing performance to solve the problem of the functional balance between flue ventilation and ashtray collection in the above-mentioned smoking device.

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 directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0030] Refer to Figures 1 to 8, in the first aspect of the present utility model, an ashtray collection mechanism is disclosed, including a first collection tube 1 and a second collection tube 2;

[0031] As a preferred embodiment, the cross-sectional diameter of the first collection tube 1 is larger than the cross-sectional diameter of the second collection tube 2.

[0032] As a preferred embodiment, the cross-sectional diameter of the first collection tube 1 is not larger than the diameter of the flue 5 of the smoking device.

[0033] It should be noted that during use, the second collection tube 2 needs to be installed inside the first collection tube 1, and a gap allowing air to pass through is left between the tube wall of the first collection tube 1 and the second collection tube 2, so that the ashtray collection mechanism installed in the smoking device can not only collect ashtray but also provide a channel for air circulation in the flue of the smoking device, thereby ensuring that the cigarette can continue to burn when the user uses the smoking device.

[0034] A plurality of first ventilation holes 11 communicating the first collection tube 1 with the outside are provided at the bottom of the first collection tube 1. The second collection tube 2 is arranged inside the first collection tube 1 so that an air ventilation cavity 101 is formed between the tube walls of the first collection tube 1 and the second collection tube 2, and a collection cavity 201 is formed through the second collection tube 2. Second ventilation holes 21 communicating the air ventilation cavity 101 and the collection cavity 201 are provided on the side wall of the second collection tube 2.

[0035] Specifically, the outside air first enters the bottom of the ashtray collection mechanism through the first ventilation holes 11 at the bottom of the first collection tube 1, and then the air enters the interior of the ashtray collection mechanism along the air ventilation cavity 101 formed by the gap between the tube walls of the first collection tube 1 and the second collection tube 2, so that the outside air is finally communicated with the flue 5 to achieve the purpose of providing oxygen for cigarette burning. And during the burning process of the cigarette in the flue 5, ashtray drops. Since the bottom of the second collection tube 2 is in a sealed state compared with the bottom of the first collection tube 1, the ashtray will fall into the collection cavity 201 formed by the second collection tube 2, thereby retaining the ashtray generated by burning in the ashtray collection mechanism 7. On the premise of ensuring continuous flue ventilation, it can reduce the pollution of the outside environment of the smoking device caused by the ashtray generated by cigarette burning.

[0036] Furthermore, when the ashtray in the smoking device is needed, the second collection tube 2 of the ashtray collection mechanism is taken out, and the ashtray in the second collection tube 2 is cleaned to complete the cleaning treatment of the ashtray inside the smoking device. Such a design also avoids the pollution of other components or structures of the smoking device body except the ashtray collection mechanism by the ashtray.

[0037] Furthermore, a silica gel ring protruding outward is provided at the inlet edge of the second collection tube 2. The second collection tube 2 can be limited and installed in the first collection tube 1 through the silica gel ring at the inlet edge. At the same time, the silica gel ring seals the gap between the first collection tube 1 and the second collection tube 2, preventing the ash dropped from the cigarette butt from falling into the ventilation cavity 101, and enabling the ash to be always retained in the collection cavity 201, so as to achieve the purpose of preventing ash leakage and reducing the pollution risk. As a preferred embodiment, the arrangement modes of the first ventilation holes 11 and the second ventilation holes 21 include uniform arrangement, array arrangement and irregular arrangement.

[0038] It should be noted that the arrangement modes of the ventilation holes in this application include but are not limited to uniform arrangement, array arrangement and irregular arrangement, as long as the air flow for cigarette combustion can be ensured. The number, shape and arrangement mode of the ventilation holes corresponding to achieving the above purpose of ensuring cigarette combustion are all acceptable.

[0039] As a preferred embodiment, a movable convex column 3 penetrating the bottom of the first collection tube 1 is provided at the bottom of the first collection tube 1. The movable convex column 3 abuts against the bottom of the second collection tube 2, and a pull rod 4 is connected to the end of the movable convex column 3.

[0040] Specifically, when cleaning the ash collection mechanism, first, the ash collection mechanism needs to be taken out from the flue 5 of the smoking device. The movable range of the movable convex column 3 is limited. When the pull rod 4 is pulled, the movable convex block 3 moves a certain distance towards the bottom of the smoking device and is then limited and fixed. The first collection tube 1 will receive the pulling force of the pull rod 4 and thus be pulled out from the flue 5 of the smoking device. Secondly, to clean the ash collection mechanism, the second collection tube 2 needs to be taken out from the first collection tube 1. By pressing the pull rod 4, the movable convex column 3 connected to the pull rod 4 will lift the second collection tube 2 after moving a certain distance, so that the second collection tube 2 becomes loose and disengages from the first collection tube 1. After cleaning the ash in the second collection tube 2, the second collection tube 2 is then installed back into the first collection tube 1, and finally the ash collection mechanism is installed back into the smoking device to complete the ash cleaning work.

[0041] Further, when the movable convex column 3 is in a non-moving state, it can lift the second collection tube 2 in the first collection tube 1 from the bottom, so as to leave a gap at the bottom between the first collection tube 1 and the second collection tube 2. This gap and the gap between the first collection tube 1 and the second collection tube 2 together form the ventilation cavity 101, which can provide a flow space for the air flowing into the ventilation cavity 101 through the first ventilation holes 11, thus solving the functional balance problem of flue ventilation and ash collection.

[0042] See Figures 1 - 8As shown in the figure, in the second aspect of the present utility model, a smoking device is disclosed, which includes an ashtray collection mechanism of the technical solution of the above embodiment. The smoking device includes a flue 5 for providing cigarette combustion, and the ashtray collection mechanism is disposed in the flue 5.

[0043] Specifically, the ashtray collection mechanism 7 can be installed in the flue 5 of the smoking device 6 by interference fit, and at the same time, the ashtray collection mechanism 7 in the flue 5 can also be installed and fixed by installing a spring flap in the flue 5.

[0044] The present utility model realizes the ashtray collection work of the smoking device through the cooperation of the first collection pipe and the second collection pipe. At the same time, the flue of the smoking device is connected to the outside air through the cooperation of the first ventilation hole and the second ventilation hole, so as to achieve the purpose of continuous cigarette combustion without affecting the sealed state of ashtray collection. It can not only reduce the environmental pollution caused by the ashtray generated by smoking, but also facilitate the user to clean the ashtray in the smoking device, solve the functional balance problem of flue ventilation and ashtray collection, and improve the user experience of using the smoking device.

[0045] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
