[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] like Figure 1-Figure 6 As shown in the figure, an embodiment of the utility model proposes a cigarette holder filter device, including a cigarette holder 1, a cigarette holder 2 and a filter assembly 3; one end of the cigarette holder 1 is connected to the cigarette holder 2, and a filter cavity 4 is formed at the connection position; the filter assembly 3 is arranged inside the filter cavity 4; the other end of the cigarette holder 1 is provided with an interface 5, and the interface 5, the filter cavity 4 and the interior of the cigarette holder 2 are connected in sequence; the interface 5 is step-shaped, and the material of the cigarette holder 1 is BMC material.

[0029] Based on the above technical solution, one end of the cigarette holder 1 is connected to the cigarette holder 2, and a filter cavity 4 is formed at the connection position, the filter assembly 3 is arranged inside the filter cavity 4, and the other end of the cigarette holder 1 is provided with an interface 5, and the interface 5, the filter cavity 4 and the interior of the cigarette holder 2 are connected in sequence; the interface 5 is stepped, and the material of the cigarette holder 1 is BMC material. The cigarette holder 1 is manufactured by utilizing the material properties of BMC, and no shrinkage will occur during injection molding, thereby ensuring that the appearance of the cigarette holder 1 is good-looking. This can improve the yield rate of manufacturing the cigarette holder 1 and effectively shorten the manufacturing cycle of the cigarette holder filter device.

[0030] BMC (Bulk Molding Compounds) is a thermosetting plastic, the full name is bulk molding compound, also known as DMC (Dough Molding Compounds). BMC is mainly composed of unsaturated polyester resin, glass fiber, quartz powder, talcum powder and other fillers, as well as various additives. BMC has excellent electrical properties, mechanical properties, heat resistance, chemical corrosion resistance and no odor, and is suitable for various molding processes. It is used to manufacture the cigarette holder 1, so that the surface of the cigarette holder 1 is very smooth, and the grease and other impurities on the surface can be cleaned arbitrarily after use.

[0031] In order to facilitate users to carry, generally, the cigarette holder filter device is in the shape of an elongated column. On this basis, in order to facilitate users to play with it, it is necessary to add some curvature to the appearance of the cigarette holder 1 and the cigarette holder 2 of the cigarette holder filter device.

[0032] It can be observed along the main viewing angle of the interface 5 that at least part of the outer contour of the figure formed by the cigarette holder 1 is an arc.

[0033] The arc conforms to the ergonomic structure of the hand, and the user can play with the cigarette holder filter device for a long time without hurting the hand.

[0034] Furthermore, when observed from the main viewing angle of the interface 5, the outer contour of the figure formed by the cigarette holder 1 includes a circle and an ellipse.

[0035] When blow-molding the cigarette holder 1, the cylindrical cigarette holder 1 is preferably blow-molded successfully, and the yield rate of the product is high.

[0036] The utility model is used to connect a cigarette product and filter the smoke generated by the burning of the cigarette product: the interface 5 can be connected to the cigarette product, and when the cigarette product is lit, the user inhales towards the cigarette holder 2, and the smoke generated by the burning of the cigarette product can be sucked into the filter cavity 4 from the interface 5, and harmful substances in the smoke will be filtered out by the filter component 3 - that is, the harmless part of the smoke is separated separately, and this part enters the user's mouth through the cigarette holder 2 for the user to inhale.

[0037] At present, some brands of cigarette products on the market have different diameters of cigarette butts. In order to be able to adapt to cigarette butts of different diameters, the shape of the interface 5 is multi-step, which is convenient for users to enjoy different brands of cigarette products.

[0038] In addition, a narrow opening is formed at the position where the interface 5 communicates with the filter chamber 4 , the inner diameter of the narrow opening is smaller than the inner diameter of the filter chamber 4 , and the inner diameter of the interface 5 increases step by step from the narrow opening to the position away from the filter chamber 4 .

[0039] The step at the position of the interface 5 connected to the filter chamber 4 can be connected to a cigarette butt of a slightly smaller size, the step in the middle of the interface 5 can be connected to a cigarette butt of another size, and the step at the position of the interface 5 away from the filter chamber 4 can be connected to a cigarette butt of a slightly larger size. In this way, users can choose cigarette products of appropriate size according to their preferences.

[0040] And when observed from the main viewing angle of the interface 5, the step shape of the interface 5 is circular, which can facilitate blow molding.

[0041] In some embodiments, the interface 5 of the present application is in a three-step shape.

[0042] The utility model uses a cigarette holder made of BMC material. The surface of the cigarette holder 1 is very smooth. In order to match it, the surface of the cigarette holder 2 needs to be smooth. When the cigarette holder 2 and the cigarette holder 1 are assembled together, the appearance can give the user a unified and coordinated feeling. If the surface of the cigarette holder 2 is rough, it will give the user a very abrupt feeling. The utility model can apply some glossy materials on the surface of the cigarette holder 2, or the material of the cigarette holder 2 is metal. Generally, the surface of the metal material is very smooth and can be directly used as the cigarette holder 2. This can avoid applying glossy materials on the surface of the cigarette holder 2, thereby shortening the product construction period.

[0043] Moreover, for the convenience of processing, the cigarette holder 1 and the cigarette holder 2 can be manufactured separately, and then assembled after manufacturing. For the convenience of assembly and subsequent cleaning and maintenance, the cigarette holder 2 and the cigarette holder 1 can be detachably connected, and the detachable connection methods include threaded connection, snap connection, magnetic connection, etc.

[0044] For the convenience of processing, the cigarette holder 1 is split into two parts. In some embodiments, the cigarette holder 1 includes a filter body 10 and an interface body 11. One end of the filter body 10 is connected to the cigarette holder 2, and a filter cavity 4 is formed at the connection position. The other end of the filter body 10 is connected to the interface body 11, and a sealing component 12 is provided at the connection position to prevent smoke from escaping from the connection position. Generally, the filter body 10 and the interface body 11 are detachably connected, and the detachable connection method includes a threaded connection, a snap connection, etc. In other embodiments, the filter body 10 can be an integral structure with the cigarette holder 2 for easy processing together.

[0045] The user's habit of smoking cigarettes can be compared to the action of "sighing" in daily life. When "sighing", the resentment, anger, etc. accumulated in the human body will be discharged from the body, thereby relaxing the body and keeping awake; the present application filters the smoke generated by the burning of cigarette products, filters out harmful substances in the smoke, and retains harmless substances for users to inhale. Users inhale and exhale smoke containing only harmless substances, and it will not affect the taste and relaxing effect.

[0046] Generally, when smoke flows in the filter chamber 4, it is necessary to ensure that there is a sufficiently large contact area between the smoke and the filter component 3 so that the filter component 3 can filter out harmful substances in the smoke to the maximum extent possible. At the same time, it is necessary to ensure that the filter component 3 does not hinder the flow of smoke.

[0047] In the filter cavity 4, the filter assembly 3 is arranged in a spiral shape along the direction of smoke flow. For example, in some embodiments, the filter assembly 3 includes a spring member 6, which is located inside the filter cavity 4, and its two ends are respectively abutted against the inner walls of the cigarette holder 1 and the cigarette holder 2, and the spiral direction of the spring member 6 is consistent with the direction of smoke flow; or, the filter assembly 3 includes a plurality of filter members 7, which are located inside the filter cavity 4, with gaps between the filter members 7, and gaps between the filter members 7 and the inner walls of the cigarette holder 1, and these filter members 7 can be arranged side by side along the direction of smoke flow.

[0048] When the smoke passes through the spring component 6 or the filter component 7, it contacts the surface of the spring component 6 or the filter component 7, and the harmful substances in the smoke will be filtered out, leaving the harmless part, which will enter the cigarette holder for the user to inhale.

[0049] In some embodiments, the material of the spring member 6 or the filter member 7 is alloy copper, nano copper or platinum-palladium alloy. Optionally, the alloy copper can be an alloy composed of copper and one or more other elements, or a nano alloy composed of nano particles of copper and other materials. Specifically, the alloy copper material is used to catalyze alkanes, alkenes, benzene series, aldehydes, acids and polycyclic aromatic hydrocarbons, etc., to filter out alkanes, alkenes, benzene series, aldehydes, acids and polycyclic aromatic hydrocarbons in the flue gas, thereby reducing the content of substances such as tar, nicotine and nitrosamines in the flue gas, and then filtering out harmful components in the flue gas.

[0050] When smoke enters the filter chamber 4, the smoke will come into contact with the surface of the filter component 7 or the spring component 6, so that the spring component 6 or the filter component 7 made of alloy copper will undergo a catalytic reaction with alkanes, alkenes, benzene series, aldehydes, acids and polycyclic aromatic hydrocarbons, thereby filtering out substances such as alkanes, alkenes, benzene series, aldehydes, acids and polycyclic aromatic hydrocarbons in the smoke, thereby effectively reducing the content of harmful components such as tar, nicotine and nitrosamines in the smoke.

[0051] To facilitate the installation of the spring component 6 or the filter component 7, a filter through hole 8 is provided inside the cigarette holder 1. The filter through hole 8 is connected to the interface 5. The filter through hole 8 and the cigarette holder 2 form a filter cavity 4, and the inner diameter of the filter through hole 8 gradually increases from the position connected to the interface 5 to the position away from the interface 5.

[0052] One end of the spring component 6 can be just stuck in the position of the communication interface 5 of the filter through hole 8, and the other end is supported by the cigarette holder 2. In this way, the cigarette holder filter device can be turned over at will without the spring component 6 rotating.

[0053] The filter components 7 of the present invention can be individual entities, which can be loaded into the filter cavity 4. In addition, in consideration of the actual size of the cigarette holder 2 and to avoid the filter component 7 from clogging the cigarette holder 2, the outer diameter of the filter component is 3 mm-10 mm.

[0054] In addition, in order to ensure that harmful substances in the smoke can be fully decomposed and filtered, the number of the filter components 7 of the present invention can be 5 or more.

[0055] In order to facilitate the arrangement of the filter components 7 along the direction of smoke flow, the utility model adopts a method of stringing the filter components 7 together through a connecting line 13.

[0056] Due to the existence of the connecting line 13, the relative distance between two adjacent filter components 7 is limited, and it is difficult for two adjacent filter components 7 to be arranged in the same position. In addition, due to the stress between the connecting line 13 and the filter components 7, there is some entanglement between the filter components 7, so that the filter components 7 can be arranged along the direction of smoke flow, and it is very rare that two filter components 7 are arranged in the same position at the same time, which also avoids congestion in the filter chamber 4.

[0057] In order to improve the filtering effect, a multi-stage filtering structure can be provided in the filter chamber 4. In some embodiments, a catalytic inner chamber 14 is provided in the filter chamber 4, and the filter assembly 3 is provided inside the catalytic inner chamber 14. A first opening 15 is provided at one end of the catalytic inner chamber 14 close to the interface 5, and a second opening 16 is provided at one end of the catalytic inner chamber 14 close to the cigarette holder 2. The first opening 15 is communicated with the smoke outlet of the interface 5, and the second opening 16 is communicated with the smoke inlet of the cigarette holder 2. The filter assembly 3 is spirally arranged in the catalytic inner chamber 14 along the direction of smoke flow, and the smoke passes through the interface 5 and The first opening 15 enters the catalytic inner chamber 5, and the smoke diffused in the catalytic inner chamber 14 can contact the inner surface of the filter component 3 and the catalytic inner chamber 14, and filtering and catalytic reactions occur. The filter component 3 is arranged in a spiral shape along the flow direction of the smoke, which can increase the contact area between the smoke and the filter component 3. Under the double catalytic action of the filter component 3 and the catalytic inner chamber 14, the filtering effect on components such as alkanes, alkenes, benzene series, aldehydes, acids and polycyclic aromatic hydrocarbons in the smoke is improved, thereby reducing the content of harmful substances such as tar, nicotine and nitrosamines in the smoke.

[0058] Optionally, the filter chamber 4 , the catalytic inner chamber 14 and the filter assembly 3 share the same axis, so that smoke enters the filter chamber 4 and diffuses, and the smoke can better contact the catalytic inner chamber 14 and the filter chamber 4 evenly.

[0059] Furthermore, the inner diameter of the first opening 15 is larger than the inner diameter of the second opening 16, and the catalytic inner chamber 14 receives the smoke input from the interface 5 through the first opening 15 with a larger inner diameter, and at the same time, the catalytic inner chamber 14 transports the smoke to the mouthpiece 2 through the second opening 16 with a smaller inner diameter. That is, the inner diameter difference between the first opening 15 and the second opening 16 is utilized to make it easier for the smoke to enter the catalytic inner chamber 14, while slowing down the rate at which the smoke flows out of the catalytic inner chamber 14, so that the smoke has more catalytic reaction time with the filter assembly 3 and the catalytic inner chamber 14, thereby improving the catalytic effect and further reducing the harmful components in the filtered smoke.

[0060] The inner diameter of the position where the interface 5 connects to the filter chamber 4 is relatively small. When the smoke leaves the interface 5 and enters the filter chamber 4, it is difficult for the smoke to diffuse evenly, but it directly contacts part of the filter component 3. This will result in the rest of the filter component 3 not being contacted with the smoke. The part of the filter component 3 that was previously in contact with the smoke has a poor effect in decomposing and filtering harmful substances due to the large amount of smoke, and there is a possibility that harmful substances are mixed in the smoke and inhaled by the user.

[0061] Therefore, it is necessary to divert the smoke entering the filter chamber 4. A diverter plate 9 is provided inside the cigarette holder 1 and at a position connected to the interface 5 of the filter chamber 4. The diverter plate 9 can divert the smoke entering the filter chamber 4 from the interface 5 so that it can be evenly diffused before contacting the filter component 3, thereby ensuring that the smoke can fully contact the filter component 3 and the harmful substances can be fully decomposed and filtered.

[0062] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
