[0026] Specifically, Figure 1 and Figure 3 As shown, when in use, the first acetate fiber filter segment 3, the first polyphenylene sulfide fiber filter segment 4, the nano material filter segment 5, the second polyphenylene sulfide fiber filter segment 6 and the second acetate fiber filter segment 7 are combined into a composite filter element, which is located inside the filter tube 2 for use to treat the flue gas. At the same time, the density of the central segment and the outer segment of the composite filter element are different, and the density of the central segment is slightly higher than that of the outer segment. When the flue gas enters, part of it enters the outer segment and part of it enters the central segment. The outer segment has a lower density and a faster flow rate, while the central segment has a higher density and a lower flow rate, so a negative pressure is formed between them. In this way, the flue gas in the central segment and the outer segment can flow through the gaps and holes between the materials for further filtering treatment.

[0027] A smoke chamber 12 is fixed to the right side of the outer tube 1, a through hole 13 is provided on the left side of the top of the smoke chamber 12, a smoke inlet groove 14 is provided on the top of the left side of the smoke chamber 12, a slider 15 is provided inside the smoke chamber 12, a buffer groove 16 is provided through the top of the left side of the slider 15, a rolling tooth 17 is fixed to the bottom end of the left side of the slider 15, a plurality of rolling teeth 17 are fixed to the bottom end of the left side of the slider 15, and the plurality of rolling teeth 17 are distributed at equal intervals, a connecting tube 18 is fixed to the right side of the slider 15, a spring 19 is provided on the outer side wall of the connecting tube 18, the right side of the connecting tube 18 extends to the outside of the smoke chamber 12, and a mouthpiece 20 is fixed to the right side of the connecting tube 18;

[0028] Specifically, Figure 1 and Figure 4 As shown, when in use, the mouthpiece 20 is pulled back, the slider 15 inside the smoke chamber 12 can be moved rightward, and the upper through hole 13 is opened. After the popping bead is put into the smoke chamber 12 along the through hole 13, the mouthpiece 20 is released, and the slider 15 can be reset with the assistance of the spring 19. During the reset process, the crushing teeth 17 and the inner wall of the smoke chamber 12 can pressurize and crush the popping bead to complete the release of the popping bead aroma;

[0029] A connecting groove 21 is provided on the left side of the cigarette holder 20, and a positioning groove 22 is provided on the right side of the cigarette holder 20. A ball bearing 23 is movably installed inside the positioning groove 22. A confluence cavity 24 is provided at the center of the ball bearing 23. A cigarette hole 25 is provided on the outer wall of the ball bearing 23. The inner side of the cigarette hole 25 extends to the inside of the confluence cavity 24. A plurality of cigarette holes 25 are provided on the outer wall of the ball bearing 23, and the plurality of cigarette holes 25 are distributed in a ring shape.

[0030] Specifically, Figure 1 and Figure 4 As shown, when in use, the confluence chamber 24 is movably mounted in the ball 23 at the tail end of the cigarette holder 20, which can help isolate the saliva of the user and dust and debris from the outside, preventing such substances from entering the interior of the device and affecting the overall use.

[0031] Working principle: When in use, the composite cigarette is inserted into the inner side of the plug-in tube 8 for fixed use, and the user uses the mouthpiece 20 to perform the smoking operation. The ball 23 is movably installed at the tail end of the mouthpiece 20 for use, which can assist in isolating saliva and debris. After the smoke enters the filter tube 2 along the plug-in tube 8 and the first ramp 9, a composite filter element composed of a first acetate fiber filter segment 3, a first polyphenylene sulfide fiber filter segment 4, a nanomaterial filter segment 5, a second polyphenylene sulfide fiber filter segment 6, and a second acetate fiber filter segment 7 is installed inside the filter tube 2 for processing the smoke. Because the density of the central section and the outer section of the composite filter element are different, the density of the central section is slightly higher than that of the outer section. When the smoke enters, part of it enters the outer section and part of it enters the central section. The outer section has a lower density and a faster flow rate, while the central section has a higher density and a lower flow rate. The smoke in the center section and the outer section can flow through the gaps and holes between the materials to achieve sufficient filtering of the smoke. The treated smoke can flow through the smoke chamber 12, the connecting groove 21, the confluence cavity 24 inside and outside the ball 23, and the smoke hole 25 to enter the user's mouth. If the mouthpiece 20 is pulled back, the slider 15 inside the smoke chamber 12 can be moved to the right, and the upper through hole 13 can be opened. At this time, the bursting bead can be put into the smoke chamber 12 through the through hole 13, and the mouthpiece 20 can be released. The slider 15 can be reset with the assistance of the spring 19. During the reset process, the crushing teeth 17 and the inner wall of the smoke chamber 12 can pressurize and crush the bursting bead to complete the release of the bursting bead aroma. The buffer groove 16 is filled with filter cotton to assist the use of the bursting bead, buffer and assist in mixing the aroma and smoke.
