[0035] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] Combine the following Figure 1-Figure 2 , through specific embodiments and application scenarios, a cigarette smoke capture trap provided by an embodiment of the utility model is described in detail.

[0038] like Figure 1 and Figure 2 As shown, the utility model provides a cigarette smoke trap, comprising: a trap body 1, an air inlet pipe 2 and an air outlet pipe 3. The trap body 1 has a containing cavity 11, and the containing cavity 11 is used to contain smoke capturing liquid.

[0039] One end of the air inlet pipe 2 is provided with a first connector 21, and the other end is inserted into the bottom of the accommodating chamber 11. One end of the air outlet pipe 3 is provided with a second connector 31, and the other end is communicated with the accommodating chamber 11.

[0040] The trap body 1 has a first state and a second state. When the trap body 1 is in the first state, the first connector 21 is used to be detachably mounted on the smoke collecting pipe 1001 , and the second connector 31 is used to be detachably mounted on the suction pipe 1201 of the suction unit 120 .

[0041] When the trap body 1 is in the second state, the first connection terminal 21 is connected to the second connection terminal 31 .

[0042] It is understandable that the cigarette sample 110 is arranged on the holder 100 of the smoking machine, the smoke collection pipe 1001 sends out the cigarette smoke, and the cigarette smoke is sucked to the processing position by the suction unit 120. In order to facilitate the detection of cigarette smoke, the pipeline between the holder 100 and the suction unit 120 is usually disassembled, and the trap with smoke capture liquid is connected to the pipeline between the holder 100 and the suction unit 120, and then the whole system is reconnected. When the trap has finished collecting the cigarette smoke, the pipes between the holder 100, the trap and the suction unit 120 are disassembled again, the trap is taken out, and then the pipes between the holder 100 and the suction unit 120 are reconnected together.

[0043] It is understandable that the suction unit 120 needs to ensure good air tightness during the process of pumping the smoke discharged from the clamp 100, otherwise it will cause cigarette smoke leakage and the suction unit 120 will not be able to pump the cigarette smoke to the designated location. The collection of cigarette smoke by the trap needs to be repeated many times, and the multiple pipe plugging and unplugging operations cannot ensure the air tightness of the entire system, and the operation is cumbersome. The cigarette smoke trap provided in the present application can ensure the air tightness of the entire system while quickly installing and disassembling the trap.

[0044] Specifically, the cigarette smoke trap provided by the present application includes a trap body 1, an air inlet pipe 2 and an air outlet pipe 3. The trap body 1 is cylindrical to form a receiving chamber 11. The receiving chamber 11 is pre-filled with a smoke collecting liquid. Generally, the smoke collecting liquid can be a detection enzyme melt. For example, lysozyme, etc. The smoke collecting liquid reacts with the relevant test chemical components in the cigarette smoke and is retained in the smoke collecting liquid, thereby realizing the collection of the relevant chemical components of the cigarette smoke by the trap.

[0045] The trap is equipped with an air inlet pipe 2 and an air outlet pipe 3. The cigarette is clamped in the clamp 100. The clamp 100 is connected to the smoke collection pipe 1001. The smoke collection pipe 1001 is connected to the air inlet pipe 2 of the trap. Specifically, Figure 1 and Figure 2As shown, the air inlet pipe 2 is inserted into the bottom of the accommodating chamber 11. One end of the air inlet pipe 2 is connected to the smoke exhaust pipe 1001, and the other end is inserted into the smoke capture liquid, so that the cigarette smoke can be directly transported to the smoke capture liquid and react chemically with the smoke capture liquid quickly. After the cigarette smoke reacts with the smoke capture liquid, it floats to the liquid surface and is accommodated in the accommodating chamber 11. One end of the air outlet pipe 3 is connected to the suction pipe 1201 of the suction unit 120, and the other end is connected to the accommodating chamber 11, so as to extract the cigarette smoke out of the capture trap and transport it to the corresponding area.

[0046] The end of the smoke collection pipe 1001 can be sleeved on the end of the first connector 21 away from the air inlet pipe 2, and then the connection between the smoke exhaust pipe 1001 and the first connector 21 can be wrapped with the help of a seal.

[0047] The connection method between the second connector 31 and the suction pipe 1201 may refer to the connection method between the first connector 21 and the smoke exhaust pipe 1001 described above, and will not be described in detail here.

[0048] Further, the end of the air inlet pipe 2 away from the trap body 1 is provided with a first connector 21. The end of the air outlet pipe 3 away from the trap body 1 is provided with a second connector 31. When the trap body 1 is connected to the pipeline between the clamp 100 and the suction unit 120, the trap body 1 is connected with the smoke collection pipe 1001 and the suction pipe 1201, and at this time, it is the first state of the trap body 1. When the trap body 1 is removed from the pipeline between the clamp 100 and the suction unit 120, the trap body 1 is disconnected from the smoke collection pipe 1001 and the suction pipe 1201, and at this time, it is the second state of the trap body 1.

[0049] Specifically, when the trap body 1 is in the first state, that is, when the trap body 1 is connected between the smoke collection pipe 1001 and the suction pipe 1201, one end of the first connecting head 21 is fixedly connected and communicated with the air inlet pipe 2, and the other end is connected and conducted with the smoke collection pipe 1001; correspondingly, one end of the second connecting head 31 is fixedly connected and communicated with the suction pipe 1201, and the other end is connected and conducted with the air outlet pipe 3.

[0050] The cigarette smoke trap of the present application is used as a complete set of a trap body 1, an air inlet pipe 2 equipped with a first connector 21, and an air outlet pipe 3 equipped with a second connector 31. When assembling, the first connector 21 is directly connected to the smoke collection pipe 1001, and then the second connector 31 is connected to the suction pipe 1201, and then the suction unit 120 is started, and the whole system can be operated, which is very convenient.

[0051] When the cigarette smoke trap is finished, the first connector 21 is directly removed from the smoke collection pipe 1001, and then the second connector 31 is removed from the suction pipe 1201. The trap body 1 switches from the first state to the second state. At this time, the air inlet pipe 2 is separated from the smoke exhaust pipe 1001, and the air outlet pipe 3 is separated from the suction pipe 1201. Then, a part of the first connector 21 and a part of the second connector 31 are clamped together, and the original pipeline between the clamp 100 and the suction unit 120 can be reset.

[0052] The utility model provides a cigarette smoke trap, wherein a trap body 1 is filled with a smoke collecting liquid, a first connector 21 is provided at one end of an air inlet pipe 2, and the other end of the air inlet pipe 2 is inserted in the smoke collecting liquid, a second connector 31 is provided at one end of an air outlet pipe 3, and the other end of the second connector 31 is used to be inserted in a position away from the smoke collecting liquid in a containing cavity 11, and when the trap body 1 is in a first state, the first connector 21 is detachably provided on a smoke collecting pipe 1001, so that the cigarette smoke reacts with the smoke collecting liquid, thereby realizing that the trap body 1 reacts with the cigarette smoke. To collect relevant chemical components, the second connector 31 is detachably arranged on the suction pipe 1201 of the suction unit 120, so that the suction unit 120 can draw out the cigarette smoke in the trap body 1; when the trap body 1 is in the second state, the first connector 21 and the second connector 31 can be quickly connected together, the cigarette smoke trap can be quickly installed and disassembled, and the pipeline between the original clamp 100 and the suction unit 120 can be quickly reset, the operation is simple, time-saving, and the airtightness of the entire system can also be guaranteed.

[0053] Specifically, in some embodiments, Figure 1 and Figure 2 As shown, the first connection head 21 includes a first connection portion 211 and a second connection portion 212. The second connection head 31 includes a third connection portion and a fourth connection portion.

[0054] When the trap body 1 is in the first state, the first connection part 211 is detachably provided on the second connection part 212, and the first connection part 211 is communicated with the second connection part 212. The third connection part is detachably provided on the fourth connection part, and the third connection part is communicated with the fourth connection part.

[0055] When the trap body 1 is in the first state, the first connection part 211 is separated from the second connection part 212, and the third connection part is separated from the fourth connection part. The first connection part 211 is connected to the fourth connection part.

[0056] It is understandable that if Figure 2As shown, the first connector 21 includes a first connecting portion 211 and a second connecting portion 212. The first connecting portion 211 and the second connecting portion 212 are adapted to each other. The first connecting portion 211 and the second connecting portion 212 are detachable. The second connecting portion 212 is fixed to the air inlet pipe 2. The second connector 31 includes a third connecting portion and a fourth connecting portion. The third connecting portion and the fourth connecting portion are adapted to each other. The third connecting portion and the fourth connecting portion are detachable. The third connecting portion is fixed to the air outlet pipe 3.

[0057] The specific structures of the first connection part 211 and the third connection part may be the same, and the specific structures of the second connection part 212 and the fourth connection part may be the same, that is, the first connection part 211 and the fourth connection part are adapted to each other.

[0058] Specifically, when the trap body 1 is in the first state, that is, the trap body 1 is connected between the clamp 100 and the suction unit 120, the first connection part 211 and the second connection part 212 are connected, so that the air inlet pipe 2 can be connected with the smoke collection pipe 1001, so that the cigarette smoke can enter the smoke collection liquid. The third connection part and the fourth connection part are connected, so that the air outlet pipe 3 can be connected with the suction pipe 1201, so that the suction unit 120 can pump the smoke of the trap body 1 out.

[0059] When the trap body 1 needs to be switched from the first state to the second state, the first connection part 211 and the second connection part 212 are separated, and the third connection part and the fourth connection part are separated to take out the part of the cigarette smoke trap except the first connection part 211 and the fourth connection part. At this time, the first connection part 211 is connected to the smoke collection pipe 1001, and the fourth connection part is connected to the suction pipe 1201. Then, the first connection part 211 and the fourth connection part are connected together, and the original pipeline between the clamp 100 and the suction unit 120 can be reset.

[0060] By quickly disassembling and assembling the internal structure of the first connector 21 and the internal structure of the second connector 31, it is possible to prevent the smoke collection pipe 1001 and the suction pipe 1201 from being easily damaged due to repeated insertion and removal of the smoke exhaust pipe 1001 and the suction pipe 1201, so as to ensure the airtightness of the entire system.

[0061] In one embodiment, taking the first connection part 211 and the second connection part 212 as an example, one end of the first connection part 211 is provided with an internal thread, and one end of the second connection part 212 is provided with an external thread adapted to the internal thread. During assembly, the internal thread and the external thread can be directly threaded to achieve a quick connection between the first connection part 211 and the second connection part 212. Optionally, the first connector 21 and the second connector 31 can be a ferrule-type pipe joint.

[0062] like Figure 1As shown, the second connection part 212 is connected to the air inlet pipe 2, and the third connection part is connected to the air outlet pipe 3. The second connection part 212 and the third connection part have different shapes. When installing the cigarette smoke trap, the user can quickly identify the air inlet end and the air outlet end of the trap body 1 according to the shapes of the second connection part 212 and the third connection part, thereby preventing the cigarette smoke trap from causing back-inhalation due to the reverse installation of the pipeline.

[0063] Furthermore, in some embodiments, the first connection part 211 and the fourth connection part are both provided with a first sealant, which is used to seal the connection between the first connection part 211 and the smoke collection pipe 1001 and / or the connection between the fourth connection part and the suction pipe 1201 .

[0064] It is understandable that the smoke collecting pipe 1001 and the suction pipe 1201 are generally made of silicone. During long-term use, the smoke collecting pipe 1001 and the suction pipe 1201 are prone to loosening. To ensure the airtightness of the entire system, the first connecting portion 211 is configured with a first sealing member.

[0065] Optionally, the first sealing member is a sealing rubber ring. After the first connecting portion 211 is connected to the end of the smoke collection pipe 1001, the sealing rubber ring is used to wrap the connection between the first connecting portion 211 and the smoke collection pipe 1001 to ensure the stability of the connection between the first connecting portion 211 and the smoke collection pipe 1001, thereby ensuring the airtightness of the entire system.

[0066] Similarly, the fourth connection part is also provided with a first sealing member. After the fourth connection part is connected to the end of the suction pipe 1201, a sealing rubber ring is used to wrap the connection between the fourth connection part and the suction pipe 1201 to ensure the stability of the connection between the fourth connection part and the suction pipe 1201, thereby ensuring the airtightness of the entire system.

[0067] In some embodiments, the first connector 21 and the second connector 31 are both CPC quick connectors. The two parts of the CPC quick connector can be assembled or disassembled by pressing the elastic clamp on the CPC quick connector.

[0068] In some embodiments, Figure 1 As shown, the cigarette smoke trap further includes an anti-backdraft member 32 .

[0069] At least a portion of the air outlet pipe 3 is arranged vertically. The anti-backsucking member 32 is provided at the portion of the air outlet pipe 3 that is arranged vertically, and the anti-backsucking member 32 is communicated with the air outlet pipe 3 .

[0070] It is understandable that due to the suction action of the suction unit 120, the closed environment of the trap body 1 and the presence of the smoke collecting liquid, it is necessary to overcome the problem of back suction of the smoke collecting liquid, and therefore, an anti-back suction member 32 is provided on the air outlet pipe 3. The anti-back suction member 32 can prevent the smoke collecting liquid from being back sucked out of the trap body 1 due to the suction action of the suction unit 120 on the cigarette smoke in the trap body 1.

[0071] Specifically, Figure 1 and Figure 2 As shown, a part of the air outlet pipe 3 is arranged vertically. The anti-backflow member 32 is arranged at the vertically arranged part of the air outlet pipe 3. The anti-backflow member 32 is connected to the air outlet pipe 3 to ensure that the suction unit 120 sucks the cigarette smoke normally. When the suction force of the suction unit 120 is too large and causes the smoke collecting liquid to enter the air outlet pipe 3, the anti-backflow member 32 can prevent the smoke collecting liquid from flowing in the direction of the suction unit 120, so that the smoke collecting liquid flows back into the accommodating chamber 11 of the trap body 1.

[0072] In some embodiments, a plurality of anti-backsucking members 32 are provided. The plurality of anti-backsucking members 32 are all arranged at the portion of the air outlet pipe 3 that is arranged vertically, and are arranged in sequence and spaced apart along the extension direction of the air outlet pipe 3 .

[0073] It is understandable that a plurality of anti-backflow members 32 are arranged in sequence and at intervals along the vertical direction, and each anti-backflow member 32 is connected to the air outlet pipe 3. The anti-backflow members 32 may be two, three, or five, etc. The anti-backflow members 32 are provided in plurality to form multiple barriers to the smoke collecting liquid that is backflowed into the air outlet pipe 3. If the smoke collecting liquid passes through the first anti-backflow member 32 smoothly, the second anti-backflow member 32 may be used to prevent the smoke collecting liquid from continuing to be transported toward the suction unit 120, and so on.

[0074] In some embodiments, the vertically arranged portion of the air outlet pipe 3 has a straight section and a diameter-reducing section, the diameter-reducing section is arranged in the middle of the straight section, and the straight section and the diameter-reducing section are connected.

[0075] The diameter of the reduced diameter section is greater than the diameter of the straight section, so that a back-sucking prevention member 32 is formed in the reduced diameter section.

[0076] It is understandable that if Figure 1 As shown, the vertically arranged pipe section of the gas outlet pipe 3 includes a straight section and a variable diameter section. The diameter of the variable diameter section is larger than the diameter of the straight section. When the smoke capture liquid passes through the variable diameter section, it will flow back into the trap body 1 due to the influence of its own gravity and tension change, thereby forming an anti-backflow member 32 in the variable diameter section. Among them, the variable diameter section can adopt a variable diameter tube with an enlarged diameter, such as a spherical tube or an inverted funnel-shaped tube.

[0077] During the whole process of preventing the smoke collecting liquid from being sucked back, the anti-backflow element 32 will further increase the contact time and contact area between the cigarette smoke and the smoke collecting liquid, thereby improving the reaction efficiency.

[0078] like Figure 1 and Figure 2 As shown, the trap body 1 has an opening communicating with the accommodating chamber 11. One end of the air outlet pipe 3 away from the second connector 31 is a spherical end, and the spherical end cover is arranged at the opening.

[0079] One end of the air inlet pipe 2 away from the first connector 21 is used to pass through the spherical end and is inserted into the bottom of the accommodating cavity 11 .

[0080] It is understandable that the conventional air outlet pipe 3 of the capture trap is directly inserted into the position slightly higher than the liquid level of the smoke capture liquid in the accommodating chamber 11. If the suction force of the suction unit 120 is slightly too large, the smoke capture liquid will be sucked back into the air outlet pipe 3. In order to further prevent the occurrence of the problem of liquid back suction in the trap body 1, the end of the air outlet pipe 3 connected to the trap body 1 is set to a spherical structure adapted to the opening of the trap body 1.

[0081] Specifically, Figure 1 and Figure 2 As shown, the end of the air outlet pipe 3 away from the second connector 31 is a spherical end. The spherical end cover is set at the opening. Among them, the connection between the spherical end and the wall at the opening can stably fix the spherical end to the opening through a sealing rubber ring to ensure the air tightness of the entire system. The air outlet pipe 3 is far away from the smoke collecting liquid and does not need to be inserted in the accommodating chamber 11. After the cigarette smoke reacts with the smoke collecting liquid, it floats up and passes through the opening and is accommodated in the spherical end. Under the action of the suction unit 120, the cigarette smoke is sucked out from the spherical end.

[0082] Furthermore, to ensure that the air intake pipe 2 is smoothly inserted into the smoke collecting liquid, a connection hole is provided on the pipe wall of the spherical end. The end of the air intake pipe 2 away from the first connector 21 is successively passed through the connection hole and the opening and inserted into the smoke collecting liquid in the accommodating chamber 11.

[0083] Furthermore, the cigarette smoke trap further comprises a second sealing member. The connection between the air inlet pipe 2 and the spherical end is sealed in the second sealing member.

[0084] It is understandable that, in order to prevent cigarette smoke from leaking from the connection hole, the cigarette smoke trap is also equipped with a second seal. The second seal can be a sealing ring. The sealing ring is wound around the connection between the air inlet pipe 2 and the spherical end to fill the gap between the air inlet pipe 2 and the spherical end to ensure the airtightness of the entire system and the efficiency of cigarette smoke collection.

[0085] Furthermore, the cigarette smoke trap further comprises a fixing seat, on which a containing hole is provided, the containing hole is adapted to the trap body 1, and at least a part of the trap body 1 is inserted into the containing hole.

[0086] It is understandable that the trap body 1 is cylindrical. The trap body 1 is generally placed on a table for use. The trap body 1 is easy to fall over during the process of capturing cigarette smoke, and may even cause the liquid in the cigarette smoke trap to spill out, thereby affecting the accuracy of the detection result of cigarette smoke and low detection efficiency.

[0087] The cigarette smoke trap is also provided with a fixing seat. The fixing seat is used to fix the position of the trap body 1 to prevent the trap body 1 from tipping over. The fixing seat is in a rectangular parallelepiped shape. The bottom surface of the fixing seat has a high flatness. In addition, anti-skid patterns can be provided on the bottom surface of the fixing seat to increase the friction between the fixing seat and the tabletop.

[0088] Specifically, a holding hole is provided on a side surface of the fixing seat away from the bottom surface thereof. The diameter of the holding hole is adapted to the outer diameter of the trap body 1. When the trap body 1 is in the first state, at least a portion of the trap body 1 is inserted into the holding hole. The fixing seat can clamp and fix the trap body 1.

[0089] When the trap body 1 is in the second state, the trap body 1 can be directly pulled out from the containing hole, which is very convenient.

[0090] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
