Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1

[0021] See also Figures 1-4The filterable spit-out cigarette holder shown in the figure includes a cigarette holder tube 1, a connecting tube 2, a sleeve cigarette tube 5, a filter assembly and a push assembly. A smoke duct 10 is opened at the center of the cigarette holder tube 1, and an extension hole 9 is opened on the cigarette holder tube 1; the connecting tube 2 is installed at one end of the cigarette holder tube 1, and a mounting hole 3 is opened on the side wall of the connecting tube 2, and a first one-way valve 4 is equidistantly provided on the connecting tube 2; one end of the sleeve cigarette tube 5 is at one end of the connecting tube 2, and the end of the sleeve cigarette tube 5 away from the connecting tube 2 is provided with a cover plate 6, and the side wall of the cover plate 6 It is connected to the end of the sleeve cigarette tube 5 through a hinge shaft 7. A smoke channel 8 connected to the connecting pipe 2 is opened inside the sleeve cigarette tube 5, and a third one-way valve is provided inside the smoke channel 8; the filter component is installed inside the connecting pipe 2 to filter the inhaled smoke and exhaled secondhand smoke; the pushing component is installed inside the sleeve cigarette tube 5 and extends through the interior of the extension hole 9 of the sleeve cigarette tube 5. The pushing component pushes and pulls the cigarette inserted inside the sleeve cigarette tube 5 to extend it out of the sleeve cigarette tube 5 or to be stored in the sleeve cigarette tube 5.

[0022] See also Figure 2-Figure 4 The filter assembly shown in the figure includes a filter cartridge 11 inserted into the connecting pipe 2, and smoke outlet holes 12 are opened at equal distances on the side wall of the filter cartridge 11. Filter cotton 13 is inserted into the interior of the filter cartridge 11. The filter cotton 13 is made of a degradable, environmentally friendly and highly adsorbent material. The degradable, environmentally friendly and highly adsorbent material is made of zeolite, activated carbon and silica in a mixed ratio.

[0023] See also Figures 1-4 The pushing assembly shown in the figure includes a cannula 14 slidably arranged inside the sleeve cigarette tube 5, a second one-way valve 23 is provided at one end of the cannula 14, and a guide block 15 is fixedly provided on the outer wall of the cannula 14, the guide block 15 is slidably arranged inside the guide groove 16, the guide groove 16 is opened on the inner wall of the cannula 14, a tooth plate 17 is provided inside the guide groove 16, and one end of the tooth plate 17 is fixedly connected to one side of the guide block 15, the end of the tooth plate 17 away from the guide block 15 passes through the connecting pipe 2 and extends to the inside of the extension hole 9, a gear 18 is meshed with one side of the tooth plate 17, and the gear 18 is rotatably connected to the inner wall of the mounting hole 3 through a rotating shaft.

[0024] When using the filter cigarette holder: first install the filter assembly inside the connecting tube 2, and then connect the two ends of the connecting tube 2 to the end of the cigarette holder tube 1 and the cover cigarette tube 5 respectively, so that the connection between the connecting tube 2, the cigarette holder tube 1 and the cover cigarette tube 5 can be achieved, and the filter assembly is located between the cigarette holder tube 1 and the cover cigarette tube 5. After the filter assembly is installed, the cover plate 6 at one end of the cover cigarette tube 5 is opened, and the butt end of the cigarette is inserted into the insertion tube 14 inside the cover cigarette tube 5, and the cigarette is pushed to move into the interior of the cover cigarette tube 5. At this time, the butt end of the cigarette can push the insertion tube 14 in the cover cigarette tube The tube 5 slides inside and drives the guide block 15 on one side to slide inside the guide groove 16, and drives the tooth plate 17 on one side of the guide block 15 to move synchronously. After one end of the tooth plate 17 is engaged with the gear 18, the cigarette is stopped at this time and the gear 18 is rotated. The rotation of the gear 18 can drive the tooth plate 17 to slide inside the connecting tube 2, so that the tooth plate 17 moves toward the inside of the extension hole 9. During the movement of the tooth plate 17, the insertion tube 14 can be driven to move toward the other end of the cigarette sleeve tube 5, and then the cigarette can be brought into the interior of the cigarette sleeve tube 5, and the cigarette can be stored at this time.

[0025] After the cigarette is stored, when the user needs to light the cigarette, the gear 18 is rotated in the opposite direction. The reverse rotation of the gear 18 can drive the tooth plate 17 to move in the opposite direction inside the connecting tube 2, pushing the guide block 15 to slide in the opposite direction inside the guide groove 16, so that the insertion tube 14 moves toward one end of the cover plate 6. At this time, one end of the cigarette inserted in the insertion tube 14 pushes the cover plate 6, so that the cover plate 6 rotates around the hinge shaft 7 as the center of circle to realize that the cover plate 6 is opened at one end of the sleeve cigarette tube 5, and one end of the cigarette extends out of the outside of the sleeve cigarette tube 5. At this time, the user lights the cigarette and can smoke the cigarette. After the cigarette is inhaled by the user, the gear 18 is rotated to drive the tooth plate 17 to move to one side of the extension hole 9, so that the lit cigarette can be stored in the interior of the sleeve cigarette tube 5, and the cover plate 6 blocks the end of the sleeve cigarette tube 5 to prevent the lit position of the cigarette end from generating harmful gas in the surrounding air and spreading to the surrounding people. The smoke that is still generated when the cigarette is not inhaled is discharged from the first one-way valve 4. At the same time, when the smoker does not inhale the cigarette, the cigarette stored in the cigarette tube 5 will naturally extinguish in the absence of oxygen for a long time, which can effectively reduce the waste of cigarette burning caused by the exposure of cigarettes to the air and reduce the harmful gases generated by the continuous burning of cigarettes exposed to the air.

[0026] When smoking, the cigarette is pushed out of the cigarette tube 5 and lit. The smoke inhaled by the user will pass through the cigarette butt, the insertion tube 14, the second one-way valve 23, and enter the filter cotton 13 in the connecting tube 2, and then enter the smoker's mouth through the mouthpiece tube 1. The inhaled smoke passes through the filter cotton 13 so that harmful gases in the smoke can be filtered, which can reduce the harmful gases from entering the smoker's mouth and effectively reduce the harm of smoking to the smoker. After the smoke enters the smoker's mouth, the smoker can exhale the inhaled smoke into the mouthpiece tube 1, and then the smoke enters the filter cotton 13 from the mouthpiece tube 1. The filter cotton 13 filters the smoke pushed out. The secondhand smoke is filtered, and the protruding secondhand smoke will be filtered by the filter cotton 13 and intercepted by the second one-way valve 23 so that it does not enter the interior of the smoke tube 5. At the same time, the third one-way valve in the smoke duct 8 is closed, which can prevent the exhaled secondhand smoke from entering the interior of the smoke tube 5, so that the exhaled secondhand smoke is collected in the filter cotton 13 and filtered by the filter cotton 13. The filtered secondhand smoke will enter the connecting pipe 2 through the smoke outlet on the filter cartridge 11, and then be discharged by the first one-way valve 4 on the connecting pipe 2, thereby realizing the filtering and discharge of the secondhand smoke, which can effectively reduce the harmful substances carried in the smoke exhaled after smoking.

[0027] The device has a simple structure and is easy for smokers to use and operate. By adding a cigarette holder tube 1, a connecting tube 2, a cigarette sleeve tube 5, a filtering component and a pushing component, it can filter the smoke generated by inhalation, exhalation and spontaneous combustion of a lit cigarette in the cigarette sleeve tube 5, thereby reducing harmful substances in the inhaled smoke, reducing the release of secondhand smoke, effectively preventing the spread of secondhand smoke, and reducing the health risks of people around.
