DETAILED DESCRIPTION OF THE EMBODIMENTS

[0043] The technical solutions in the embodiments of the present invention are clearly and completely described hereinafter with reference to the drawings in the embodiments of the present invention. It is obvious that the described embodiments are only some of the embodiments of the present invention instead of all embodiments. All other embodiments obtained by the ordinary person skilled in the art based on the embodiments of the present invention without creative efforts are within the protection scope of the present invention.

[0044] The device for automatically detruding the cigarette butt is composed of a cigarette clamp 1, a cigarette fixer 2, a support ring 3, a cigarette butt detruding sliding ring 4, an air outlet end housing 5, a metal gasket 6, and a spring 7.

[0045] The cigarette clamp 1 is preferably made of plastic having a certain elasticity. As shown in FIG. 6, an overall structure of the cigarette clamp 1 is funnel-shaped in the longitudinal direction. Two cigarette clamping sheets 8 extending in an inward radial direction are provided on one end of the cigarette clamp 1 to clamp the cigarette. Two elastic sheets 9 in the periphery direction of the device are provided on front ends of the cigarette clamping sheets 8. When the elastic sheet 9 is in contact with the sloped surface of the trapezoid platform 13 on the cigarette fixer 2 and ascends along the sloped surface, the cigarette clamping sheets 8 are opened to relieve the clamping to the cigarette. Four positioning protrusion blocks 10 extending in a radial direction along an exterior of the device are provided on the other end of the cigarette clamp 1. The four positioning protrusion blocks 10 are embedded in the four positioning grooves 11 on an inner wall of the cigarette butt detruding sliding ring 4. When the cigarette butt detruding sliding ring 4 slides, the metal gasket 6 is driven to slide. The metal gasket 6 pushes the cigarette clamp 1 to slide, then the cigarette clamp 1 compresses the spring 7, and the spring 7 is compressed. In the sliding process of the cigarette clamp 1, the two cigarette clamping sheets 8 gradually approach to each other due to the elasticity thereof. When the two cigarette clamping sheets 8 approach to each other for a certain extent, the cigarette butt is clamped tightly and driven to move to the outer side. After the cigarette butt moves for a certain distance, the portion of the cigarette butt filter inserted into the fastening and sealing section of the cigarette fixer 2 is removed (at this time, the elastic sheet 9 on the cigarette clamping sheet 8 has not been in contact with the sloped surface of the trapezoid platform 13 on the cigarette fixer). The cigarette clamp 1 proceeds to move forward, the elastic sheet 9 on the cigarette clamping sheet 8 is in contact with the sloped surface of the trapezoid platform 13 on the cigarette fixer 2, and gradually moves upward along the sloped surface. In this process, the clamping action of the cigarette clamping sheet 8 on the cigarette is gradually relieved until the cigarette clamping sheet 8 is not in contact with the cigarette at all in the end. At this time, the cigarette butt can be smoothly detruded. When the manual force acted on the cigarette butt detruding sliding ring 4 is relieved, the cigarette butt detruding sliding ring 4 and the cigarette clamp 1 are reset automatically through the elasticity of the spring 7. When the cigarette clamp 1 is reset (i.e. when the cigarette clamp 1 is in the initial position of the device in the natural state or the traditional cigarette 24 is inserted into the initial natural state, see FIG. 9), an outer surface of one end of the second sliding groove 19 on the support ring 3 is in contact with the cigarette clamp 1 and pushes the cigarette clamp 1 outwards, so that the cigarette clamp 1 is in a released state during the automatic reset, which facilitates the smooth insertion of the next cigarette. When the cigarette butt detruding sliding ring 4 is rotated, the cigarette butt detruding sliding ring 4 transmits torque to the cigarette clamp 1 through the four positioning protrusion blocks 10 embedded in the groove 20 of the inner wall of the cigarette butt detruding sliding ring 4. Then, the cigarette clamp 1 transmits torque to the side facet of the first sliding groove 12 on the cigarette fixer 2 and the side facet of the second sliding groove 19 on the support ring 3 through the side facet of the cigarette clamping sheet 8 (the cigarette clamping sheet 8 radially passes through the first sliding groove 12 of the cigarette fixer 2 and the second sliding groove 19 of the support ring 3). Thus, when the cigarette butt detruding sliding ring 4 rotates in a peripheral direction, the cigarette clamp 1, the cigarette fixer 2, and the support ring 3 are synchronously driven to rotate in the peripheral direction.

[0046] As shown in FIG. 5, the cigarette fixer 2 is preferably made of plastic having a certain elasticity. An overall external structure of the cigarette fixer 2 is cylindrical in shape. Two first sliding grooves 12 are provided on the cigarette fixer 2. The cigarette clamping sheet on the cigarette clamp 1 passes through the first sliding groove 12 and is movable in the axial direction of the device in the first sliding groove 12. Two trapezoid platforms 13 with sloped surface are provided on one end of the first sliding groove 12. The elastic sheet 9 on the cigarette clamping sheet 8 can slide along the sloped surface of the trapezoid platform 13, so that the cigarette clamping sheet 8 is opened to relieve the clamping of the cigarette butt. A circular connection hole 14 is provided in the middle of the other end of the cigarette fixer 2. Two convex points 15 used for positioning are provided on the inner wall of the connection hole 14. The connection hole 14 corresponds and is connected to the boss 22 on a center of a cross section of one end of the air outlet end housing 5. The convex point 15 on the inner wall of the connection hole 14 is correspondingly matched with the positioning arc-shaped concave point 23 on the boss 22 of the center of the cross section of the end of the air outlet end housing, thereby opening and closing the traditional cigarette airflow channel. Two traditional cigarette arc-shaped airflow channels 16 are provided on the outer side of the circular connection hole 14. When the cigarette butt detruding sliding ring 4 is rotated, the inner side peripheries of the four positioning grooves 11 on the inner wall of the cigarette butt detruding sliding ring 4 transmit torque to the cigarette clamp 1 through the four positioning protrusion blocks 10 of the cigarette clamp 1, thereby driving the cigarette clamp 1 to rotate. The cigarette clamp 1 transmits the torque to a side facet of the first sliding groove 12 on the cigarette fixer 2 and a side facet of the second sliding groove 19 on the support ring 3 through a side facet of the cigarette clamping sheet 8 (the cigarette clamping sheet 8 radially passes through the first sliding groove 12 of the cigarette fixer 2 and the second sliding groove 19 of the support ring 3). When the cigarette clamp 1 rotates, the cigarette fixer 2 is driven to rotate. During rotation, when positions of the two traditional cigarette arc-shaped airflow channels 16 on the cigarette fixer 2 correspond to (overlap) positions of the two traditional cigarette arc-shaped airflow through holes 21 on the air outlet end housing 5, the traditional cigarette airflow channel is opened; at this time, the cigarette clamp 1 rotates by 90 degree clockwise or anticlockwise, so that when the positions of the two arc-shaped airflow channels 16 on the cigarette fixer 2 are perpendicular to (not correspond to) the positions of the two traditional cigarette arc-shaped airflow through holes 21 on the air outlet end housing 5, the traditional cigarette airflow channel is closed. A portion of the cigarette fixer 2 between a cross section of the traditional cigarette arc-shaped airflow channels 16 and the first sliding groove 12 has an inner diameter of 7.5 mm, and is a cigarette fastening portion and a cigarette circumferential flow sealing portion, which fastens and fixes the cigarette, and forms a sealing space in the periphery of the cigarette. In this way, air is prevented as much as possible from entering the device through the periphery of the cigarette to ensure that the smoke generated by the combustion of the cigarette enters the device through the inside of the cigarette. The inner diameter of the first sliding groove 12 of the cigarette fixer 2 gradually increases from the bottom of one end closed to the traditional cigarette arc-shaped airflow channels 16 to an open end of the cigarette fixer 2, and the maximum inner diameter is 8.0 mm. During the process of the cigarette clamp 1 sliding towards a front end of the device, before the elastic sheet 9 on the cigarette clamping sheet 8 touches the sloped surface of the trapezoid platform 13 on the cigarette fixer 2, the cigarette butt gets detached from the fastening section of the cigarette clamp 1. When the cigarette clamping sheet 8 clamps the cigarette and continues to slide forward, the inner diameter of the cigarette fixer 2 where the cigarette reaches is gradually larger than the diameter of the cigarette. When the elastic sheet 9 on the cigarette clamping sheet 8 is in contact with the sloped surface of the trapezoid platform 13 on the cigarette fixer 2, and gradually moves upward along the sloped surface, the cigarette clamping sheet 8 gradually relieves the cigarette until the cigarette clamping sheet 8 does not clamp the cigarette at all in the end. At this time, the cigarette butt can automatically slide from the device by means of inclining the end of the device containing the cigarette butt downwards by a certain angle, which realizes convenient, easy and smooth cigarette butt detruding.

[0047] In use, the cigarette butt detruding sliding ring 4 is rotated to drive the cigarette clamp 1 and the cigarette fixer 2 to rotate, so that the traditional cigarette arc-shaped airflow channels 16 on one end of the cigarette fixer 2 correspond to (overlap) the traditional cigarette arc-shaped airflow through holes 21 on the air outlet end housing 5, thus opening the traditional cigarette airflow channel of the device. The smoke generated by the combustion of the cigarette inserted at the front end is exported through the traditional cigarette arc-shaped airflow channels 16 on one end of the cigarette fixer 2 and the traditional cigarette arc-shaped airflow through holes 21 on the air outlet end housing 5.

[0048] In order to make the smoke generated by the combustion of the cigarette inserted at the front end of the device not exit through the traditional cigarette arc-shaped airflow channels 16 on one end of the cigarette fixer 2 and the traditional cigarette arc-shaped airflow through holes 21 on the air outlet end housing 5, the cigarette butt detruding sliding ring 4 is rotated to drive the cigarette clamp 1 and the cigarette fixer 2 to rotate, so that the traditional cigarette arc-shaped airflow channels 16 on one end of the cigarette fixer 2 are perpendicular to (not correspond to) the traditional cigarette arc-shaped airflow through holes 21 on the air outlet end housing 5, thus closing the traditional cigarette air channel of the device. At this time, the smoke generated by the combustion of the cigarette inserted at the front end of the device cannot exit.

[0049] In order to convert the device for automatically detruding the cigarette butt into a device for smoking the electronic cigarette, a power supply may be provided inside the cavity of the air outlet end housing 5, or a non-connecting end of the air outlet end housing 5 is connected to the power supply and then connected to the electronic cigarette atomizer and the suction nozzle to form a hybrid smoking device, which can smoke traditional cigarettes and electronic cigarettes, and automatically detrude the traditional cigarette butts.

[0050] The above-mentioned embodiment is merely the preferred embodiment of the present invention, and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements within the spirit and principle of the present invention should be included within the protection scope of the present invention.
