[0030] Embodiment 1:

[0031] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The utility model discloses a smoke filtering reaction device, which includes a cigarette holder 1, a cigarette holder 2, a filter bin 3 and at least one sheet assembly 4. In the present embodiment, the cigarette holder 1 and the cigarette holder 2 are sequentially arranged along the smoke flow direction, the filter bin 3 is arranged between the cigarette holder 1 and the cigarette holder 2, and the filter bin 3 is provided with a receiving cavity 31; the sheet assembly 4 includes a plurality of reaction sheets 41, and the reaction sheets 41 are distributed at intervals in the receiving cavity 31, so as to form a smoke passage connecting the cigarette holder 1 and the cigarette holder 2 in the receiving cavity 31. Preferably, a smoke passage connecting the cigarette holder 1 and the cigarette holder 2 is formed in the accommodating cavity 31 by the reaction sheets 41 distributed at intervals along the direction of smoke flow, so that the smoke flowing from the cigarette holder 1 to the cigarette holder 2 contacts the surface of the reaction sheet 41 in the smoke passage, so that the reaction sheet 41 catalytically reacts with harmful components in the smoke, effectively filtering out harmful components in the smoke. Moreover, the reaction sheet 41 mainly contacts the smoke using the larger surface areas on both sides. Therefore, by reducing the thickness of the reaction sheet 41, the same volume of material can form a reaction sheet 41 with a larger contact area in the smoke passage of the same size, thereby achieving improved filtering effect while saving production costs.

[0032] In this embodiment, the thickness of the reaction sheet 41 is 0.1 mm-8 mm, wherein the thickness of the reaction sheet 41 can also be optimized by comprehensively considering factors such as the physical properties of the reaction sheet 41 and the air pressure generated by the flue gas in the flue gas passage. Preferably, the thickness of the reaction sheet 41 is 0.1 mm-2 mm; optionally, the number of the sheet assemblies 4 can be adjusted according to factors such as the number and size of the accommodating cavities 31. Optionally, a plurality of the reaction sheets 41 can be distributed in a maze-like manner along the direction of flue gas flow, so that the flue gas flowing from the cigarette holder 1 to the cigarette holder 2 flows through the maze-like flue gas passage, so that the flue gas interacts with the reaction sheets 4 during the flow process. 1 contacts the surface of the reaction sheet 41 and a catalytic reaction occurs; optionally, the sheet assembly 4 may include a plurality of groups of reaction sheets 41, each group of reaction sheets 41 includes a plurality of reaction sheets 41, and a plurality of reaction sheets 41 in the same group constitute a part of the smoke passage (for example, a small section of the smoke passage, a gap, etc.), so that the plurality of groups of reaction sheets 41 together constitute the whole of the smoke passage, and when the smoke flows from the cigarette holder 1 through the smoke passage to the cigarette holder 2, the smoke passes through the parts of each group of reaction sheets 41 in turn, driving the smoke to contact the surface of the reaction sheets 41 during the flow, so that the reaction sheets 41 and harmful components in the smoke undergo a catalytic reaction.

[0033] Optionally, the reaction sheet 41 can be made of any material that can catalyze harmful components in the flue gas. When the flue gas contacts the surface of the reaction sheet 41 during the flow process, the reaction sheet 41 can catalyze the harmful components in the flue gas, thereby effectively filtering the harmful components in the flue gas; preferably, the reaction sheet 41 is made of nano-copper, and nano-copper is used to catalyze alkanes, alkenes, benzene series, aldehydes, acids and polycyclic aromatic hydrocarbons, etc., to achieve filtering of substances such as 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. Specifically, when the smoke enters the smoke passage, the smoke will contact the surface of the reaction sheet 41, so that the reaction sheet 41 made of nano copper will react with alkanes, alkenes, benzene series, aldehydes, acids and polycyclic aromatic hydrocarbons, thereby filtering out 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. Further, the reaction sheet 41 can also be made of alloy copper composed of copper and one or more other elements or a nano copper alloy composed of nano copper and nano particles of other materials.

[0034] See also Figure 2Preferably, at least one smoke-passing hole 42 is provided on the reaction sheet 41. That is, when the smoke flows from the cigarette holder 1 to the cigarette holder 2 through the smoke-passing channel, the smoke flows through the smoke-passing hole 42, driving the smoke to contact with the surface of the reaction sheet 41 during the flow, so that the reaction sheet 41 and the harmful components in the smoke undergo a catalytic reaction. Optionally, the diameter of the reaction sheet 41 is equal to the inner diameter of the accommodating cavity 31, so that the plurality of reaction sheets 41 divide the accommodating cavity 31 into a plurality of gaps, and the adjacent gaps are connected through the smoke-passing hole 42, thereby forming the smoke-passing channel connecting the cigarette holder 1 and the cigarette holder 2. For the convenience of description, the gap between the adjacent reaction sheets 41 is referred to as the first gap. When the smoke flows from the cigarette holder 1 to the cigarette holder 2 through the filter chamber 3, the smoke can flow in the plurality of smoke-passing holes 42 and the first gap forming the smoke-passing channel until it flows into the cigarette holder 2, so that the smoke can contact with the reaction during the flow. The reaction sheet 41 contacts the surface of the reaction sheet 41, thereby driving the reaction sheet 41 to catalyze a reaction with harmful components in the flue gas; further, a plurality of smoke-passing holes 42 are provided on the reaction sheet 41, so that the smoke can flow between adjacent first gaps through the plurality of smoke-passing holes 42, thereby realizing the multi-directional movement of the smoke in the smoke-passing channel, improving the fluidity of the smoke in the smoke-passing channel, and increasing the number of surface contacts between the smoke and the reaction sheet 41; optionally, the diameter of the reaction sheet 41 is smaller than the inner diameter of the accommodating cavity 31, that is, the gap between the reaction sheet 41 and the accommodating cavity 31 is matched. For the convenience of description, the gap between the reaction sheet 41 and the accommodating cavity 31 is recorded as the second gap. Therefore, when the smoke flows from the cigarette holder 1 to the cigarette holder 2, it can flow in the smoke-passing holes 42 and in the second gap, thereby further expanding the multi-directional movement of the smoke in the smoke-passing channel.

[0035] Furthermore, the flue gas flow velocity in the flue gas passage can be adjusted by limiting the diameter of the flue gas through hole 42. Preferably, the sum of the diameters of the flue gas through holes 42 on each of the reaction sheets 41 is less than 8 mm. That is, the reaction sheet 41 may be provided with only one flue gas through hole 42 with a diameter less than 8 mm, or the reaction sheet 41 may be provided with a plurality of flue gas through holes 42, and the sum of the diameters of the plurality of flue gas through holes 42 is less than 8 mm, thereby limiting the flue gas flow velocity in the flue gas passage to avoid excessive flue gas flow velocity, which results in too short a contact time between the reaction sheet 41 and the flue gas, and inability to fully catalyze the reaction with the harmful components in the flue gas, thereby affecting the filtering effect. Optionally, the sum of the diameters of the flue gas through holes 42 on each of the reaction sheets 41 is 4 mm-8 mm, which can avoid excessive flue gas flow velocity, which results in the reaction sheet 41 being unable to effectively filter the harmful components in the flue gas, and can also ensure that the flue gas has sufficient flow velocity in the flue gas passage, providing consumers with a comfortable use experience.

[0036] See also Figure 2 , Figure 3 and Figure 4 In this embodiment, the sheet assembly 4 further includes an assembly connecting rod 43, which is disposed in the accommodating cavity 31, and the reaction sheet 41 is connected to the assembly connecting rod 43. Specifically, the plurality of reaction sheets 41 are sequentially connected in series through the assembly connecting rod 43, so that the plurality of reaction sheets 41 are stably fixed in the accommodating cavity 31. Optionally, the assembly connecting rod 43 is connected in series at the center of the reaction sheet 41, so that the assembly connecting rod 43 can fix the reaction sheet 41 conveniently.

[0037] See also Figure 2 , Figure 3 and Figure 4Preferably, both ends of the assembly connecting rod 43 along the flue gas flow direction are connected to the limiting sheet 44, and at least one flue gas through hole 45 is provided on the limiting sheet 44. The diameter of the reaction sheet 41 is less than or equal to the diameter of the limiting sheet 44, and the diameter of the limiting sheet 44 is less than or equal to the diameter of the accommodating cavity 31. Optionally, the limiting sheet 44 and the reaction sheet 41 are made of the same material. Optionally, the limiting sheet 44 can also be made of nano copper, that is, the limiting sheet 44 is substantially the reaction sheet 41 with a larger diameter. Optionally, the diameter of the limiting sheet 44 is larger than the diameter of the reaction sheet 41, and the diameter of the accommodating cavity 31 is larger than the diameter of the limiting sheet 44, that is, relative to the second gap, the gap between the limiting sheet 44 and the accommodating cavity 31 is smaller, so that the assembly connecting rod 43 can be better positioned in the accommodating cavity 31 by having the limiting sheets 44 with a diameter larger than the reaction sheet 41 at both ends, thereby realizing the positioning of the reaction sheet 41 connected in series on the assembly connecting rod 43, which can effectively reduce the unstable shaking of the sheet assembly 4. For the convenience of description, the gap between the limiting sheet 44 and the accommodating cavity 31 is recorded as the third gap. When the smoke flows from the cigarette holder 1 to the cigarette holder 2 through the smoke passage, the smoke flows into the accommodating cavity 31 from the smoke through hole 45 opened on the limiting sheet 44 close to the cigarette holder 1, or flows in from the third gap close to the cigarette holder 1. The smoke in the accommodating cavity 31 flows into the cigarette holder 2 from the smoke through hole 45 opened on the limiting sheet 44 close to the cigarette holder 2, or flows into the cigarette holder 2 from the third gap close to the cigarette holder 1. After the smoke enters the accommodating cavity 31, it flows between the smoke through hole 42, the first gap and the second gap, driving the smoke to contact the surface of the reaction sheet 41, so that the reaction sheet 41 and the harmful components in the smoke undergo a catalytic reaction. Optionally, the diameter of the accommodating cavity 31 is equal to The diameter of the limiting sheet 44 is utilized to cooperate with the accommodating cavity 31, so as to limit the position of the assembly connecting rod 43, and further limit the reaction sheet 41 connected in series on the assembly connecting rod 43, which can effectively prevent the sheet assembly 4 from unstable shaking. When the smoke flows from the cigarette holder 1 to the cigarette holder 2 through the smoke passage, the smoke can only flow into the accommodating cavity 31 from the smoke through hole 45 on the limiting sheet 44 close to the cigarette holder 1, and the smoke in the accommodating cavity 31 flows into the cigarette holder 2 from the smoke through hole 45 on the limiting sheet 44 close to the cigarette holder 2. After the smoke enters the accommodating cavity 31, it will diffuse in the smoke through hole 42 and the first gap, driving the smoke to contact with the surface of the reaction sheet 41, so that the reaction sheet 41 can catalyze the harmful components in the smoke.

[0038] See also Figure 2 , Figure 3 and Figure 4 , further, at least one separation gasket 46 is provided between adjacent reaction sheets 41, and the separation gasket 46 is connected to the assembly connecting rod 43. That is, the reaction sheets 41 and the separation gaskets 46 are sequentially staggered and connected in series on the assembly connecting rod 43. Specifically, by providing the separation gaskets 46 between adjacent reaction sheets 41, the spacing between adjacent reaction sheets 41 is reliably limited, that is, the size of the first gap is limited, so that the flue gas can flow in the first gap, so that the flue gas can contact the surface of the reaction sheet 41. Optionally, the center of the reaction sheet 41 and the center of the separation gasket 46 are both connected to the assembly connecting rod 43 to prevent the reaction sheet 41 from tilting and affecting the flow of flue gas between adjacent reaction sheets 41.

[0039] Preferably, the size of the first gap can be adjusted according to the catalytic capacity of the reaction sheet 41 and the actual filtering requirements. Optionally, the spacing between the reaction sheets 41 can be adjusted by increasing the number of the separation gaskets 46 provided between adjacent reaction sheets 41, thereby achieving the adjustment of the size of the first gap. Optionally, the spacing between the reaction sheets 41 can be adjusted by changing the thickness of the separation gaskets 46. Preferably, the thickness of the separation gaskets 46 is 1 mm-10 mm.

Optionally, the first connection portion is an internal thread structure, and the second connection portion is an external thread structure cooperating with the first connection portion, so that the filter bin 3 and the cigarette holder 2 can be quickly assembled and disassembled through the threaded connection between the first connection portion and the second connection portion. Furthermore, the cigarette holder 2 can be disassembled from the filter bin 3 to remove the sheet assembly 4 for cleaning or replacement. Specifically, the filter outer bin and / or the cigarette holder 2 can be twisted to drive the second connection part to separate from the first connection part, and the sheet assembly 4 can be taken out from the accommodating cavity 31 for cleaning or replacement. After cleaning or replacement, the sheet assembly 4 is reassembled into the accommodating cavity 31, and the first connection part is driven to be threadedly connected with the second connection part, so that the filter outer bin and the cigarette holder 2 can be reconnected.

[0041] Furthermore, the limiting sheet 44 and the assembly connecting rod 43 can be detachably connected by means of threaded connection or snap connection, and a through hole is provided at the center of the reaction sheet 41 and the center of the separation gasket 46. During assembly, one limiting sheet 44 is first connected to one end of the assembly connecting rod 43, and then multiple separation gaskets 46 and multiple reaction sheets 41 are staggered and movably connected in series to the assembly connecting rod 43 one by one, and finally another limiting sheet 44 is connected to the other end of the assembly connecting rod 43. When a component needs to be cleaned or replaced, any limiting sheet 44 can be removed from the assembly connecting rod 43, and then the separation gasket 46 and the reaction sheet 41 can be removed from the assembly connecting rod 43 for easy cleaning or replacement, thereby improving the cleaning effect and reducing the maintenance cost. At the same time, the number of the separation gaskets 46 and the reaction sheets 41 can be increased or decreased during the disassembly and assembly process to achieve the adjustment of the filtering effect.

The third gap arranged at the both side ends of the assembling connecting rod 43 is smaller than the second gap at other positions, so as to better position the assembling connecting rod 43 in the accommodating cavity 31, and then realize the positioning of the reaction sheets 41 connected in series on the assembling connecting rod 43. Preferably, at least one smoke through hole 42 is opened on the reaction sheet 41, and at least one separator is arranged between adjacent reaction sheets 41, so that a first gap is formed between adjacent reaction sheets 41.

The smoke in the accommodating cavity 31 flows into the cigarette holder 2 from the smoke through hole 45 opened on the limiting sheet 44 close to the cigarette holder 2.

For the convenience of description, the gap between adjacent reaction sheets 41 is recorded as the first gap, and the gap between the reaction sheet 41 and the reaction tube 5 is recorded as the fourth gap, that is, the smoke can flow between the smoke passage hole 42, the fourth gap and multiple first gaps, and the smoke passage is composed of the smoke passage hole, the fourth gap and the first gap, so that the smoke contacts the surface of the reaction sheet 41 and the reaction tube 5 during the flow process, so that the reaction sheet 41 and the reaction tube 5 catalytically react with harmful components in the smoke. Optionally, the diameter of the reaction sheet 41 is equal to the inner diameter of the reaction, so that The plurality of reaction sheets 41 divide the reaction tube 5 into a plurality of first gaps, and adjacent first gaps are connected through the smoke through holes 42, that is, the smoke passage is composed of the smoke through holes 42 and the first gaps. When the smoke flows from the cigarette holder 1 to the cigarette holder 2, the smoke flows through the smoke through holes 42 and the first gaps in the reaction tube 5 in sequence until it flows into the cigarette holder 2, so that the smoke can contact the surfaces of the reaction tube 5 and the reaction sheets 41 in each first gap when flowing, thereby driving the reaction sheets 41 and the reaction tube 5 to catalyze the harmful components in the smoke; further, the reaction sheet 41 is provided with a plurality of smoke through holes 42, so that the smoke can flow between adjacent first gaps through the plurality of smoke through holes 42, thereby realizing multi-directional movement of the smoke in the reaction tube 5, improving the fluidity of the smoke in the smoke passage, and increasing the number of times the smoke contacts the surface of the reaction sheet 41.

[0048] Furthermore, the flue gas velocity in the flue gas passage can be adjusted by limiting the diameter of the flue gas through hole 42, thereby adjusting the flue gas velocity in the reaction tube 5. Preferably, the sum of the diameters of the flue gas through holes 42 on each of the reaction sheets 41 is less than 8 mm. That is, the reaction sheet 41 may be provided with only one flue gas through hole 42 with a diameter less than 8 mm, or the reaction sheet 41 may be provided with a plurality of flue gas through holes 42, and the sum of the diameters of the plurality of flue gas through holes 42 is less than 8 mm, thereby limiting the flue gas velocity in the flue gas passage, and avoiding excessive flue gas velocity, which results in too short a contact time between the reaction sheet 41 and the reaction tube 5 and the flue gas, and is unable to fully catalyze the harmful components in the flue gas, thereby affecting the filtering effect. Optionally, the sum of the diameters of the smoke through holes 42 on each of the reaction sheets 41 is 4 mm-8 mm, which can avoid the reaction sheet 41 and the reaction tube 5 being unable to effectively filter harmful components in the smoke due to excessive smoke flow rate, while also ensuring that the smoke has a sufficient flow rate in the smoke passage, providing consumers with a comfortable user experience.

[0049] See also Figure 2 , Figure 5 and Figure 6 In this embodiment, the sheet assembly 4 further includes an assembly connecting rod 43, which is disposed in the reaction tube 5, and the reaction sheet 41 is connected to the assembly connecting rod 43. Specifically, the plurality of reaction sheets 41 are sequentially connected in series through the assembly connecting rod 43, so that the plurality of reaction sheets 41 are stably fixed in the reaction tube 5. Optionally, the assembly connecting rod 43 is connected in series at the center of the reaction sheet 41, so that the assembly connecting rod 43 can fix the reaction sheet 41 conveniently.

[0050] See also Figure 2 , Figure 5 and Figure 6Preferably, both ends of the assembly connecting rod 43 are connected to a limiting sheet 44, and at least one smoke through hole 45 is formed on the limiting sheet 44. The diameter of the reaction sheet 41 is less than or equal to the diameter of the limiting sheet 44, and the diameter of the limiting sheet 44 is less than or equal to the diameter of the reaction tube 5. Optionally, the limiting sheet 44 and the reaction sheet 41 are made of the same material, that is, the limiting sheet 44 is substantially the reaction sheet 41 with a larger diameter. Optionally, the diameter of the limiting sheet 44 is larger than the diameter of the reaction sheet 41, and the diameter of the reaction tube 5 is larger than the diameter of the limiting sheet 44, that is, relative to the fourth gap, the gap between the limiting sheet 44 and the reaction tube 5 is smaller, so that the assembly connecting rod 43 can be better positioned in the reaction tube 5 by having the limiting sheets 44 with a diameter larger than the reaction sheet 41 at both ends, thereby realizing the positioning of the reaction sheet 41 connected in series on the assembly connecting rod 43, which can effectively reduce the unstable shaking of the sheet assembly 4. For the convenience of description, the gap between the limiting sheet 44 and the reaction tube 5 is recorded as the fifth gap; when the smoke flows from the cigarette holder 1 to the cigarette holder 2 through the smoke passage, the smoke flows into the reaction tube 5 from the smoke through hole 45 opened on the limiting sheet 44 close to the cigarette holder 1, or flows in from the fifth gap close to the cigarette holder 1, and the smoke in the reaction tube 5 flows into the cigarette holder 2 from the smoke through hole 45 opened on the limiting sheet 44 close to the cigarette holder 2, or flows into the cigarette holder 2 from the fifth gap close to the cigarette holder 2, wherein after the smoke enters the reaction tube 5, it can flow in the first gap, the fourth gap and the smoke through hole 42, driving the smoke to contact the surfaces of the reaction sheet 41 and the reaction tube 5, so that the reaction sheet 41 and the reaction tube 5 catalyze a reaction with harmful components in the smoke; optionally, the diameter of the reaction tube 5 is equal to the limiting sheet 44, and the cooperation between the limiting sheet 44 and the accommodating cavity 31 is utilized to limit the position of the assembly connecting rod 43, and further limit the reaction sheet 41 connected in series on the assembly connecting rod 43, which can effectively prevent the sheet assembly 4 from unstable shaking. When the smoke flows from the cigarette holder 1 to the cigarette holder 2 through the smoke passage, the smoke can only flow into the accommodating cavity 31 from the smoke through hole 45 on the limiting sheet 44 close to the cigarette holder 1, and the smoke in the accommodating cavity 31 flows into the cigarette holder 2 from the smoke through hole 45 on the limiting sheet 44 close to the cigarette holder 2. After the smoke enters the accommodating cavity 31, it can flow in the smoke through hole 42, the fourth gap and the first gap, driving the smoke to contact the surface of the reaction sheet 41 and the reaction tube 5, so that the reaction sheet 41 and the reaction tube 5 can catalyze the harmful components in the smoke.

[0051] See also Figure 2 , Figure 5 and Figure 6 , further, at least one separation gasket 46 is provided between adjacent reaction sheets 41, and the separation gasket 46 is connected to the assembly connecting rod 43. That is, the reaction sheets 41 and the separation gaskets 46 are sequentially staggered and connected in series on the assembly connecting rod 43. Specifically, by providing the separation gaskets 46 between adjacent reaction sheets 41, the spacing between adjacent reaction sheets 41 is reliably limited, that is, the size of the first gap is limited, so that the flue gas can flow in the first gap, so that the flue gas can contact the surface of the reaction sheet 41. Optionally, the center of the reaction sheet 41 and the center of the separation gasket 46 are both connected to the assembly connecting rod 43 to prevent the reaction sheet 41 from tilting and affecting the flow of flue gas between adjacent reaction sheets 41.

[0052] Preferably, the spacing between adjacent reaction sheets 41 can be adjusted according to the catalytic capacity of the reaction sheets 41 and the actual filtering requirements. Optionally, the spacing between the reaction sheets 41 can be adjusted by increasing the number of the separation gaskets 46 provided between adjacent reaction sheets 41, thereby adjusting the size of the first gap. Optionally, the spacing between the reaction sheets 41 can be adjusted by changing the thickness of the separation gaskets 46. Preferably, the thickness of the separation gaskets 46 is 1 mm-10 mm.

[0053] See also Figure 1 , Figure 2 , Figure 5 and Figure 6Optionally, the cigarette holder 1 and the filter bin 3 are integrally formed to prevent unfiltered smoke from leaking out, and a first connection portion is provided at one end of the filter bin 3 close to the cigarette holder 2, and a second connection portion cooperating with the first connection portion is provided at one end of the cigarette holder 2 close to the filter bin 3, and the filter bin 3 and the cigarette holder 2 are detachably connected through the first connection portion and the second connection portion, so that the filter bin 3 and the cigarette holder 2 can be detachably connected. Optionally, the first connection portion is an internal thread structure, and the second connection portion is an external thread structure cooperating with the first connection portion, so that the filter bin 3 and the cigarette holder 2 can be quickly assembled and disassembled through the threaded connection between the first connection portion and the second connection portion. Furthermore, the cigarette holder 2 can be disassembled from the filter compartment 3, so that the sheet assembly 4 and the reaction tube 5 can be taken out for cleaning or replacement. Specifically, the filter outer compartment and / or the cigarette holder 2 can be twisted to drive the second connection part to separate from the first connection part, so that the sheet assembly 4 and the reaction tube 5 can be taken out from the accommodating chamber 31 for cleaning or replacement. After cleaning or replacement, the sheet assembly 4 is reassembled into the reaction tube 5, and then the reaction tube 5 is assembled into the accommodating chamber 31, and then the first connection part is driven to be threadedly connected with the second connection part, so that the filter outer compartment and the cigarette holder 2 can be reconnected.

[0054] Furthermore, the limiting sheet 44 and the assembly connecting rod 43 can be detachably connected by means of threaded connection or snap connection, and the center of the reaction sheet 41 and the center of the separation gasket 46 are both provided with a through hole. During assembly, firstly connect one limiting sheet 44 to one end of the assembly connecting rod 43, and then connect multiple separation gaskets 46 and multiple reaction sheets 41 to the assembly connecting rod 43 in an interlaced manner one by one, and finally connect another limiting sheet 44 to the other end of the assembly connecting rod 43, and then assemble. The completed sheet assembly 4 is placed in the reaction tube 5. When it is necessary to clean or replace a certain component, the sheet assembly 4 can be taken out from the reaction tube 5 first, and then any one of the limiting sheets 44 can be removed from the assembly connecting rod 43, and the separation gasket 46 and the reaction sheet 41 can be removed from the assembly connecting rod 43 for easy cleaning or replacement, thereby improving the cleaning effect and reducing the maintenance cost. At the same time, the number of the separation gasket 46 and the reaction sheet 41 can be increased or decreased during the disassembly and assembly process to achieve the adjustment of the filtering effect.

Preferably, the reaction sheets 41 are made of nano copper, and both side ends of the assembly connecting rod 43 are connected with the limiting sheets 44 formed by the reaction sheets 41 with a larger diameter. The fifth gap arranged at the two side ends of the assembly connecting rod 43 is smaller than the fourth gap at other positions, so as to better position the assembly connecting rod 43 in the reaction tube 5, thereby realizing the positioning of the reaction sheets 41 connected in series on the assembly connecting rod 43. Preferably, at least one smoke through hole 42 is opened on the reaction sheet 41, and the adjacent reaction sheets 4 At least one separator is arranged between the two adjacent reaction sheets 41, so that a first gap is formed between the adjacent reaction sheets 41, and the smoke can enter and exit the first gap through the smoke through hole 42. When the smoke flows from the cigarette holder 1 to the cigarette holder 2 through the smoke through channel, the smoke flows into the accommodating cavity 31 from the smoke through hole 45 opened on the limiting sheet 44 close to the cigarette holder 1, and the smoke in the accommodating cavity 31 flows into the cigarette holder 2 from the smoke through hole 45 opened on the limiting sheet 44 close to the cigarette holder 2. After the smoke enters the accommodating cavity 31, it can flow between the smoke through hole 42, the first gap and the fourth gap, driving the smoke to contact the surfaces of the reaction sheet 41 and the reaction tube 5, so that the reaction sheet 41 and the reaction tube 5 catalytically react with the harmful components in the smoke, further improving the degree of smoke catalysis and optimizing the filtering effect of harmful components in the smoke.
