In the embodiment of the utility model, a dual filtration cigarette holder 100 is provided for filter the flue gas of cigarette, reduce harmful substance such as tar in the flue gas, promote the cigarette quality, the user of being convenient for inhales.

As shown in fig. 1 and 2, the dual-filter cigarette holder 100 includes a hollow sleeve 10, and a first filter element 20 and a second filter element 30 both disposed inside the sleeve 10. The sleeve 10 is cylindrical and has a cylindrical through hole therein. In this embodiment, the first filter element 20 and the second filter element 30 are both metal filter elements, such as aluminum filter elements, which are convenient to be washed with clean water after use and reused. The side of the first filter element 20 close to the second filter element 30 is detachably connected through threads.

In one embodiment, the sleeve 10 also has a mouthpiece 40 at an end adjacent the second cartridge 30. In this embodiment, the side of the sleeve 10 adjacent the first filter element 20 is defined as the front section, the side adjacent the second filter element 30 is defined as the rear section, and the mouthpiece 40 is located at the rear end of the sleeve 10. Specifically, a screw 31 is arranged at one end of the second filter element 30 away from the first filter element 20, and a screw groove 41 matched with the screw 31 is arranged in the mouthpiece 40. The threaded rod 31 is adapted to engage the threaded channel 41 to secure the mouthpiece 40 to the second cartridge 30 to facilitate removal of the mouthpiece 40.

Further, an end of the screw 31 away from the mouthpiece 40 is provided with an annular limiting projection 32. The two ends of the limiting protrusion 32 respectively abut against one end of the sleeve 10 close to the mouthpiece 40, thereby isolating the sleeve 10 from the mouthpiece 40. The surfaces of the stop lugs 32 are flush with the surfaces of the sleeve 10 and the mouthpiece 40.

In the embodiment of the present invention, the first filter element 20 and the second filter element 30 both include a front filter chamber 51 and a rear filter chamber 52 which are distributed along the axial direction of the sleeve 10 and are not communicated with each other. The front filter chamber 51 and the rear filter chamber 52 are not communicated with each other, and the ends far away from each other are communicated with the outside.

The side walls of the first filter element 20 and the second filter element 30 are respectively provided with a first air hole 53 communicated with the corresponding front filter cavity 51 and a second air hole 54 communicated with the corresponding rear filter cavity 52. The pore diameter of the first pores 53 is smaller than that of the second pores 54, for example, the first pores 53 are micropores, and the second pores 54 are macropores. When the smoke passes through the first air hole 53 and the second air hole 54 in sequence, the flow rate of the smoke is changed.

Further, the outer wall of one end of the first filter element 20 and the outer wall of the two ends of the second filter element 30 are both provided with annular bosses 55. Further, the annular bosses 55 are provided with sealing rings 56. The sealing ring 56 is in interference abutment with the inner wall of the sleeve 10, thereby enhancing the seal between the annular boss 55 and the inner wall of the sleeve 10.

Specifically, the first filter element 20 and the second filter element 30 are connected along the axial direction of the sleeve 10, so that the rear filter cavity 52 of the first filter element 20 and the front filter cavity 51 of the second filter element 30 are surrounded and communicated. The annular boss 55 of the first filter element 20, the annular boss 55 of the second filter element 30 at the end close to the first filter element 20, the outer wall of the first filter element 20 and the inner wall of the sleeve 10 are jointly enclosed to form a first lampblack chamber 57. The two annular bosses 55 of the second filter element 30, the outer wall of the second filter element 30 and the inner wall of the sleeve 10 together enclose a second soot chamber 58.

When smoke enters from one end of the sleeve 10 close to the first filter element 20 and then flows out from one end close to the second filter element 30, the smoke sequentially passes through the front filter cavity 51 of the first filter element 20, the first air hole 53 of the first filter element 20, the first lampblack chamber 57, the second air hole 54 of the first filter element 20, the rear filter cavity 52 of the first filter element 20, the front filter cavity 51 of the second filter element 30, the first air hole 53 of the second filter element 30, the second lampblack chamber 58, the second air hole 54 of the second filter element 30 and the rear filter cavity 52 of the second filter element 30, and as the aperture of the second air hole 54 is smaller than that of the first air hole 53, the flow speed of the smoke entering the first lampblack chamber 57 and the second lampblack chamber 58 is reduced, so that tar and magazine smoke in the smoke are mixed and condensed on the inner walls of the first lampblack chamber 57 and the second lampblack chamber 58.

Meanwhile, the structures of the first filter element 20 and the second filter element 30 at the filtering function are almost the same, so that the first filter element 20 can be normally used only by the second filter element 30 after being detached, and the filtering degree of the smoke is adjusted. Of course, more filter elements can be added to adjust the filtering degree.

Further, in one embodiment, a smoke insertion groove 11 is formed inside a side of the sleeve 10 adjacent to the first filter element 20. The cigarette insertion groove 11 is used for inserting and fixing one end of the cigarette. The bottom of the smoke insertion groove 11 communicates with the front filter chamber 51 of the first filter cartridge 20, thereby allowing smoke to enter the front filter chamber 51 of the first filter cartridge 20.

Further, the cigarette insertion groove 11 includes a plurality of cylindrical and coaxial insertion grooves 111. The apertures of the plurality of slots 111 decrease from the end far away from the first filter element 20 to the end close to the first filter element 20. In the embodiment, the slot 111 is a three-segment type, which is suitable for cigarettes with three standard sizes, i.e. thick, medium and thin, on the market. Of course, the aperture of the slot 111 can be set according to the specific size of the cigarette.

Furthermore, the inner diameter of each section of the insertion groove 111 is continuously reduced from the end far away from the first filter element 20 to the end close to the first filter element 20, so that the cigarette can be fixed in an interference fastening manner conveniently.

To sum up, the utility model provides a dual filtration cigarette holder 100 is equipped with first filter core 20 and second filter core 30 along axial direction in sleeve pipe 10 to be equipped with first gas pocket 53 and second gas pocket 54 at the filter core, the outer wall through the filter core encloses with sleeve pipe 10's inner wall and establishes formation first oil smoke room 57 and second oil smoke room 58, when the flue gas passes through sleeve pipe 10, because the aperture of first gas pocket 53 is less than the aperture of second gas pocket 54, can lead to the transform of air velocity, make in the flue gas tar, smoke and dust impurity can mix to condense and adhere to in first oil smoke room 57 and second oil smoke room 58, the quality of cigarette has been promoted. Meanwhile, after the first filter element 20 is detached, the second filter element 30 can be used normally and independently, so that the filtering degree of the smoke can be adjusted.

The invention is not limited solely to that described in the specification and the embodiments, and additional advantages and modifications will readily occur to those skilled in the art, and it is not intended to be limited to the specific details, representative apparatus, and illustrative examples shown and described herein, without departing from the spirit and scope of the general concept as defined by the appended claims and their equivalents.
