[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1:

[0034] This utility model relates to a cigarette holder filter, such as Figures 1-5 As shown, it includes a first filter element 2, a cigarette insertion tube 1 connected to one end of the first filter element 2, and a smoking tube 5 connected to the other end of the first filter element 2 via a connector.

[0035] Among them, such as Figure 3 As shown, the two ends of the cigarette insertion tube 1 are respectively provided with a cigarette insertion hole 11 and a connecting cavity 12 for connecting the first filter element 2. The cigarette insertion hole 11 is the smoke inlet end of the cigarette insertion tube 1, which is used to insert the cigarette mouthpiece to fix the cigarette axially at the end of the cigarette insertion tube 1. Preferably, the cigarette insertion hole 11 is stepped and deepened to accommodate cigarettes of different sizes.

[0036] Combination Figure 4 As shown, the first filter element 2 has a cylindrical structure, with one end sealed and inserted into the interior of the connecting cavity 12. At least a portion of the periphery of the insertion end of the first filter element 2 and the inner wall of the connecting cavity 12 enclose a space 25. The two ends of the first filter element 2 are respectively provided with an inlet 21 and an outlet 22 axially. The inlet 21 is located at the insertion end of the first filter element 2 in the connecting cavity 12. The inlet 21 and outlet 22 are connected to the space 25 through micropores 23 and through holes 24 formed on the periphery of the first filter element 2, respectively. The smoke from burning cigarettes enters the inlet 21, is accelerated through the micropores 23, enters the space 25, and is then discharged through the outlet 22. During this process, the smoke, accelerated by the micropores 23, impacts the inner wall of the space 25, causing harmful substances in the smoke, such as tar and nicotine, to be adsorbed or condensed in the space 25, thus achieving preliminary filtration.

[0037] Furthermore, at least one set of sealing rings is sleeved around the periphery of the first filter element 2. These sealing rings allow for an interference fit between the first filter element 2 and the connecting cavity 12, improving the sealing performance and reducing smoke leakage. Preferably, at least one set of sealing rings is located between the smoke inlet end of the cigarette insert 1 and the spacer space 25. When harmful substances such as tar and nicotine accumulate inside the spacer space 25, the first filter element 2 can be pulled out of the connecting cavity 12, allowing the sealing rings to scrape out the harmful substances for easy cleaning.

[0038] Furthermore, to ensure a more stable fit of the sealing ring, at least one set of limiting annular grooves 26 are provided on the periphery of the first filter element 2 for fitting the sealing ring. The limiting annular grooves 26 effectively restrict the axial movement of the sealing ring, preventing it from falling out of the connecting cavity 12 when the first filter element 2 is pulled out. Based on the preferred configuration of the sealing ring described above, at least one set of limiting annular grooves 26 is located between the smoke inlet end of the cigarette insert 1 and the spacer space 25.

[0039] like Figure 5 As shown, the connector includes a connecting pipe 3 at both ends that is detachably connected to the first filter element 2 and the smoking pipe 5, respectively.

[0040] Specifically, the end of the first filter element 2 furthest from its insertion end is its end, and its end is provided with threaded ribs on its periphery. The connecting pipe 3 includes a connecting groove 31 formed at one end that is threaded to the end of the first filter element 2, and a connecting head 32 formed at its other end that engages with the smoking tube 5. The connecting head 32 is a frustum-shaped structure extending axially, which can be inserted into and engaged with the smoking tube 5. Its specific engaging structure is the same as the engaging structure between the arc-shaped protrusion and the arc-shaped groove commonly found in the market, and will not be described in detail here.

[0041] It should be noted that the aperture of the other end of the smoking tube 5 is smaller than the aperture of its insertion end with the connector 32. A second filter element 4 can be replaceably inserted into the inside of the smoking tube 5 through its insertion end with the connector 32. The second filter element 4 is confined within the smoking tube 5 by the insertion of the connector 32, forming a secondary filtration structure in conjunction with the first filter element 2. The second filter element 4 is a common cigarette filter element made of cellulose acetate, polypropylene fiber, etc., which will not be described in detail here.

[0042] Example 2:

[0043] Figures 6-8 The second embodiment of the present invention is shown, which differs from the first embodiment in that a third filter element 6 that can be detachably connected is provided between the first filter element 2 and the connecting pipe 3.

[0044] Among them, such as Figure 7As shown, the third filter element 6 includes a bottle 61 for holding the filtrate, and an exhaust pipe 62 and a guide pipe 63, both connected to the bottle 61 at one end. The connection between the exhaust pipe 62 and the bottle 61 should be higher than the connection between the guide pipe 63 and the bottle 61. A connecting groove 31 is also provided at the end of the exhaust pipe 62 away from the bottle 61, and the end of the guide pipe 63 away from the bottle 61 has the same threaded structure as the end of the first filter element 2. In use, the first filter element 2 can be disassembled from the connecting pipe 3. The end of the first filter element 2 is threaded into the connecting groove 31 on the exhaust pipe 62 to install the first filter element 2 onto the exhaust pipe 62. The disassembled connecting pipe 3 can be threadedly connected to the guide pipe 63 through the connecting groove 31, thus forming a second combination with a triple filtration structure, as shown below. Figure 6 As shown; in this embodiment, the filtrate is water, which is filled into the bottle 61 through the exhaust pipe 62 and / or the guide pipe 63. The filling height of the filtrate should be higher than the connection between the guide pipe 63 and the bottle 61, and lower than the connection between the exhaust pipe 62 and the bottle 61, so that the flue gas can pass through the filtrate first and then be discharged from the exhaust pipe 62. Since harmful substances such as nitrogen oxides and nicotine in the flue gas are soluble in water, the flue gas can be further purified and filtered when it passes through the filtrate, thereby reducing the inhalation of harmful substances.

[0045] Furthermore, in order to reduce the amount of filtrate to be filled so that filtration can be effectively carried out even with a small amount of filtrate, a conduit can be extended from the end of the smoke inlet tube 63 into the bottle body 61 and close to the bottom surface of the bottle body 61 so that even with a small amount of filtrate, it can be submerged in the conduit.

[0046] Furthermore, to facilitate the disassembly, assembly, and carrying of the cigarette filter, as well as the filling of the filter fluid, such as Figure 8 As shown, the bottle body 61 can be configured as an upper bottle body 611 and a lower bottle body 612 detachably connected to the upper bottle body 611. Preferably, for example, the upper bottle body 611 and the lower bottle body 612 are connected by threads; the connection method is the same as that between the cap and the bottle body of existing mineral water bottles, and will not be described in detail here.

[0047] Meanwhile, the exhaust pipe 62 and the guide pipe 63 are detachably connected to the lower bottle body 612 and the upper bottle body 611, respectively. Preferably, the exhaust pipe 62 and the guide pipe 63 are threadedly connected to the lower bottle body 612 and the upper bottle body 611, respectively.

[0048] In this embodiment, a threaded through hole is provided at the top of the upper bottle body 611, and a threaded head adapted to the threaded through hole is provided at the end of the smoke exhaust pipe 62; a threaded through hole is also provided around the lower bottle body 612, and a threaded head adapted to the threaded through hole is provided at the end of the smoke guide pipe 63.

[0049] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
