[0029] A specific embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0030] The utility model discloses a mouthpiece structure suitable for a cigarette holder and having multiple filters. Figure 1 、 Figure 2 and Figure 3 As shown, it includes a bite body, the internal structure of the bite body is provided with an axially penetrating smoke channel, and the smoke channel is provided with a purification module, a fine filter module and a spiral filter module.

[0031] In this embodiment, if Figure 3As shown, the bite body includes a main shell 10 and a joint 20 engaged with the axial front end of the main shell 10; wherein the joint 20 has an axially through first channel, and the first channel includes a front mounting portion located at its axial rear end, and the main shell 10 has an axially through second channel engaged with the first channel to form a flue gas channel, and the second channel includes a rear mounting portion located at its axial front end, and the purification module, the fine filter module and the spiral filter module are limitedly installed between the front mounting portion and the rear mounting portion.

[0032] In the above scheme, if Figure 3 As shown, the rear end of the connector 20 is inserted into the front port of the main shell 10, that is, the rear end of the connector 20 is inserted into the front of the rear mounting part. Preferably, the front inner diameter of the rear mounting part is adapted to the caliber of the rear end of the connector 20, and the rear inner diameter of the rear mounting part is adapted to the interior of the front mounting part; a first annular groove 21 is provided on the rear end of the connector 20, and a first annular rib 12 is correspondingly provided in the front part of the rear mounting part, which is connected to the first annular groove 21 by an interference fit. In this way, the connector 20 is stably connected to the main shell 10 through the cooperation between the first annular groove 21 and the first annular rib 12; preferably, a positioning piece 23 extending backward is provided on the rear end of the connector 20, and a positioning port 13 corresponding to the front port of the main shell 10 is provided. In order to ensure the joining effect between the connector 20 and the main shell 10, the thickness of the positioning piece 23 is preferably the same as the wall thickness of the main shell 10.

[0033] In this embodiment, if Figure 3 As shown, a magnetic head 70 is also provided in the front port of the connector 20. The magnetic head 70 includes an annular suction head portion 71 located in front of the connector 20, and a cylindrical connecting portion 72 connected to the annular suction head portion 71 and extending into the connector 20. The cylindrical connecting portion 72 is provided with a second annular rib 721. A second annular groove 22 is correspondingly provided in the front port of the connector 20 and is connected to the second annular rib 721 by an interference fit. In this way, the magnetic head 70 is firmly connected to the connector 20 through the cooperation between the first annular rib and the second annular groove 22.

[0034] In some other specific implementation schemes, the connector 20 and the main housing 10, as well as the magnetic head 70 and the connector 20, can also be fixedly connected by threaded connection, snap connection, rotational snap connection, etc.

[0035] In this embodiment, if Figure 3As shown, the purification module, the fine filtration module and the spiral filtration module are arranged in sequence in the smoke channel of the mouthpiece body along the direction of smoke flow (from front to back); specifically, the purification module includes a filter 30 embedded in the front mounting portion of the joint 20, and the filter 30 is a mouthpiece filter 30 that can be purchased in bulk on the market. The filter 30 has a hollow filter cavity and the front and rear ends corresponding to the axial direction are respectively provided with an inlet and an outlet connected to the filter cavity. The inlet and outlet are preferably a multi-porous structure, and the filter cavity of the filter 30 is filled with at least one filter material, such as filter cotton, activated carbon, etc.; in this way, the purification module can filter and adsorb the smoke flowing through it through the filter material inside it to remove harmful substances therein.

[0036] Such as 3 and Figure 4 As shown, the refinement filter module includes a refinement columnar body 40 (cylinder) arranged on the rear side of the filter 30, and a plurality of dividing ribs 41 extending from the front end to the rear end are arranged on the outer peripheral wall of the refinement columnar body 40 at circumferential intervals (preferably evenly spaced), and a refinement channel 42 that axially guides the front and rear ends is formed between two adjacent dividing ribs 41. In this way, the refinement channel H is formed between the corresponding refinement channel 42 of the refinement columnar body 40 and the inner wall of the rear mounting part (the inner wall of the flue gas channel). The refinement columnar body 40 can divert the flue gas to the various refinement channels H on the outer wall and guide it through; in this way, the flue gas in the flue gas channel will impact the end face of the refinement columnar body 40 when flowing through the refinement columnar body 40, so that harmful substances in the flue gas condense and remain on the refinement columnar body 40 to achieve a purification effect. At the same time, the large flue gas can be divided into multiple small flue gases through the refinement channel H to improve the subsequent filtering and purification effect.

[0037] In the above scheme, it is preferred that a support ring 60 is further supported and arranged between the refined columnar body 40 and the filter 30, the front end of the support ring 60 is pressed against the rear end face of the filter 30, and the outlet on the filter 30 is located in the inner hole of the support ring 60; the front end of the refined columnar body 40 is pressed against the rear end face of the support ring 60 and the ports of several refined grooves 42 are located in the annular surface of the support ring 60, and each refined groove 42 is connected with the inner hole of the support ring 60 through at least one recess 43 provided on the front end face of the refined columnar body 40. Such an arrangement not only facilitates the control of the connecting cross-sectional area between the recess 43 and the inner hole of the support ring 60, but also avoids the direct connection between the flue gas flowing in the flue gas channel and the refined groove 42, thereby effectively improving the filtering and purification effect.

[0038] like Figure 3 and Figure 5As shown, the spiral filtration module includes a spiral columnar body 50 abutting against the rear end face of the refinement columnar body 40, and a spiral groove 51 is provided on the outer wall of the spiral columnar body 50, so that the spiral groove 51 corresponding to the refinement columnar body 40 and the inner wall of the rear mounting part (the inner wall of the flue gas channel) cooperate to form a spiral channel G, and the spiral channel G is connected to the refinement channel 42; in this way, the flue gas passing through the refinement channel H will impact the groove wall of the spiral groove 51 so that the harmful substances condense and remain on the spiral columnar body 50, and at the same time, the spiral groove 51 on the spiral columnar body 50 also effectively extends the flow path of the flue gas, thereby achieving a better purification effect.

[0039] In the above scheme, the spiral columnar body 50 is preferably a hollow tube structure, and the rear end of the spiral columnar body 50 is provided with at least one notch 52 that communicates with the notch of the spiral groove 51. In this way, when the spiral columnar body 50 is pressed against the rear wall of the rear mounting part, the smoke flowing along the spiral groove 51 can enter the inner cavity of the tube body through the notch 52 to achieve communication with the second channel of the main shell 10.

[0040] In this embodiment, the filter 30 , the support ring 60 , the thinned columnar body 40 and the spiral columnar body 50 are sequentially abutted and connected and are positionally clamped between the front wall of the front mounting portion and the rear wall of the rear mounting portion.

[0041] In this embodiment, if Figure 2 and Figure 3 As shown, an oxygen-enriched hole 11 connected to the flue gas channel is provided on the bite body. The oxygen-enriched hole 11 is correspondingly arranged on the side wall of the main shell 10 opposite to the positioning plate 23 and is connected to the thinning channel H. In this way, the amount of oxygen entering can be increased through the oxygen-enriched hole 11, thereby reducing the formation of carbon monoxide.

[0042] In some other specific embodiments, the filter 30 of the purification module can also be arranged on the rear side of the spiral filtration module. The flue gas is filtered and purified by passing through the fine filtration module, the spiral filtration module, and the filter 30 in sequence to better remove harmful substances in the flue gas and reduce the damage of the flue gas to the human body.

[0043] Compared with the existing technology, the utility model has a simple and reasonable structure. Through the multiple filtering structure composed of the purification module, the fine filtering module and the spiral filtering module, it can more effectively remove harmful substances in the inhaled smoke, thereby effectively reducing the damage caused by smoking to the human body; at the same time, the design of the oxygen-enriched holes can increase the inhalation of oxygen and reduce the formation of carbon monoxide.

[0044] The above disclosure is only an embodiment of the present invention, but the present invention is not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
