[0022] Figure 1 This is a schematic diagram of a cigarette puff-by-puff smoke collection device provided by an embodiment of the present invention. The cigarette puff-by-puff smoke collection device includes: a smoking machine turntable 1, a suction device 2, a smoke passage control module 3, and a target collection container 4; the smoking machine turntable 1 and the suction device 2 are connected through a smoke passage 5; a through hole is provided at a first position of the smoking machine turntable 1, and the through hole is connected to the first end of the smoke passage 5; wherein, the smoking machine turntable 1 is used to move at least one cigarette to be tested in a burning state to the first end of the smoke passage 5; the first end of the suction device 2 is connected to the second end of the smoke passage 5, and is used to suck up the cigarette to be tested and discharge the sucked cigarette smoke; the smoke passage control module 3 is connected to the second end of the suction device 2, and is used to control the valve state of at least one solenoid valve, and based on the valve state, transport the cigarette smoke discharged by the suction device 2 to the target collection container; wherein, the solenoid valve is the control valve in the smoke passage of the smoke passage control module 3.

[0023] The smoking machine turntable 1 can be a turntable-shaped device with a drive shaft at its center, which can be driven to rotate by a motor. The turntable shape can be arbitrary, optionally circular, elliptical, or polygonal. Optionally, the smoking machine turntable 1 can be a commonly used smoking machine. The smoking machine turntable 1 can be used to fix at least one cigarette to be tested, so that the cigarette to be tested can be tested by rotation. Multiple slots are evenly distributed on the smoking machine turntable for fixing the cigarette to be tested. It should be noted that the smoking machine turntable 1 used in this example can be circular, as the circular turntable design can make the smoking test process more uniform and stable. To enable the detection of the smoke from cigarettes placed on the smoking machine turntable, the smoke from these cigarettes can first be collected. Then, the smoking cigarette in its burning state can be drawn in using the suction device 2. To facilitate the suction of the cigarette smoke using the suction device 2, the smoking machine turntable 1 and the suction device 2 can be connected via a smoke duct 5. A through hole is provided at a first position on the smoking machine turntable 1, connecting to the first end of the smoke duct. Furthermore, when the smoking machine turntable 1 is in operation, at least one burning cigarette placed on it can be moved to the first end of the smoke duct. The first position can be any position on the smoking machine turntable 1, optionally, it can be the position on the smoking machine turntable 1 where the cigarette holder is placed.

[0024] The smoke passage 5 can be a channel for transporting cigarette smoke. The smoke passage 5 can be a pipe of any material, such as PVC, stainless steel, galvanized sheet, or aluminum foil composite fiberglass cloth.

[0025] The suction device 2 can be a device for suctioning and exhausting flue gas. The suction device 2 may include a piston and a solenoid valve. For example, the suction device 2 may be a suction syringe with a piston and a solenoid valve.

[0026] In this embodiment, a piston is used to draw in and expel cigarette smoke, and a solenoid valve is used to control the opening and closing of the air inlet at the first end and the air outlet at the second end of the suction device 2. This allows for the drawing in of the cigarette to be tested and the expulsion of the drawn-in cigarette smoke. In this embodiment, the first end of the suction device 2 is connected to the second end of the smoke channel 5. The suction device 2 can simulate the smoking process. When the suction device 2 draws in the cigarette to be tested using the piston, the air inlet at the first end is open, and the air outlet at the second end is closed, thus obtaining cigarette smoke. Afterwards, the piston is used to expel the drawn-in cigarette smoke. During expulsion, the air inlet at the first end is closed, and the air outlet at the second end is open, allowing the drawn-in cigarette smoke to be expelled through the second end.

[0027] The flue gas passage control module 3 can be a device for controlling the gas flow direction in the flue gas passage. This device can control the gas flow direction in the flue gas passage by controlling the valve state of the solenoid valve. The flue gas passage control module 3 is connected to the second end of the suction device 2 and can be used to control the valve state of at least one solenoid valve. Based on the valve state, the cigarette smoke discharged from the second end of the suction device can be delivered to the target collection container 4. The solenoid valve can be a control valve in the flue gas passage of the flue gas passage in the flue gas passage control module 3. When the solenoid valve is in the open state, smoke can flow through the flue gas passage; when the solenoid valve is in the closed state, smoke cannot flow through the flue gas passage. The valve state of the solenoid valve includes an open state and a closed state.

[0028] The target collection container 4 can be a container used to collect the smoke produced after cigarettes are smoked. The target collection container 4 can be any type of gas collection container; optionally, it can be a gas collection bag.

[0029] In specific implementation, while the smoking machine turntable 1 is in operation, at least one cigarette under test, currently burning, can be moved to the first end of the smoke passage via the turntable 1. Further, the suction device 2 can suck up the cigarette under test moved to the first end of the smoke passage and discharge the sucked-up cigarette smoke. Further, the smoke passage control module 3 can control the valve status of at least one solenoid valve it contains. Subsequently, based on the valve status, the cigarette smoke discharged by the suction device 2 can be delivered to the target collection container 4.

[0030] The technical solution of this utility model embodiment provides a cigarette puff-by-puff smoke collection device, which includes: a smoking machine turntable, a suction device, a smoke passage control module, and a target collection container; the smoking machine turntable and the suction device are connected through a smoke passage; a through hole is provided at a first position of the smoking machine turntable, and the through hole is connected to a first end of the smoke passage; wherein, the smoking machine turntable is used to move at least one cigarette under combustion to be tested to the first end of the smoke passage; the first end of the suction device is connected to a second end of the smoke passage, and is used to suck up the cigarette under test and discharge the sucked cigarette smoke; the smoke passage control module is connected to the second end of the suction device, and is used to control the valve state of at least one solenoid valve, so as to transport the cigarette smoke discharged by the suction device to the target collection container based on the valve state. The device of this utility model achieves the effect of collecting cigarette smoke generated by at least one cigarette under combustion puff by puff, thereby improving the smoke collection efficiency.

[0031] Based on the above embodiments, a schematic diagram of the composition of the smoking machine turntable 1 is shown below. Figure 2 , Figure 2 Figure a in the diagram is a top view of the rotating disc 1 of the smoking machine. Figure 2 Figure b in the diagram is a front view of the smoke extraction machine turntable 1. (See figure below.) Figure 2 As shown, the smoking machine turntable 1 includes a turntable motor 101, a turntable 102, and at least one cigarette holder 103. The cigarette holder 103 is mounted on the turntable 102 and is used to hold a cigarette to be tested with its lit end in a burning state. The turntable motor 101 controls the rotation of the turntable 102 according to preset rotation parameters to move the cigarette to be tested held by the cigarette holder 103 to the first end of the smoke channel 5.

[0032] The turntable motor 101 provides power to the turntable, driving its rotation. The turntable motor 101 can be positioned below the turntable 102, saving space, improving efficiency, ensuring the reliability and durability of the transmission mechanism in the smoking machine turntable 1, and preventing rotational problems caused by transmission failures. The turntable motor 101 can be connected to the turntable 102 in various ways, including direct connection (directly connecting the motor shaft to the turntable shaft); bearing connection (one bearing mounted on the motor shaft and the other on the turntable shaft); or coupling connection (couplings are typically used in pairs, one on the motor shaft and the other on the turntable shaft). Preset rotation parameters include a preset rotation angle and a preset rotation cycle. The preset rotation angle can be related to the angle between two adjacent through holes on the turntable 102. That is, rotating according to the preset rotation angle, the cigarettes to be detected on the turntable 102 can be sequentially moved to the first end of the smoke channel. The preset rotation cycle can be the turntable rotation cycle. The preset rotation period can be any value, and can be selected as once every 3 seconds, once every 5 seconds, or once every 10 seconds, etc.

[0033] The turntable 102 can be a device for moving the cigarette to be tested to a target position by rotation. At least one cigarette holder 103 is provided on the turntable 102, which can be used to hold the cigarette to be tested while it is burning. It should be noted that the cigarette holder can be fixed to the turntable 102 in at least two ways: optionally, by means of a slot; or by means of a through hole.

[0034] Optionally, the cigarette holder 103 has a cigarette insertion port of the target shape on its first end and a threaded ventilation tube on its second end, which is connected to the cigarette insertion port. The turntable 102 has through holes at multiple second positions, the threads of which match the threads of the ventilation tube of the cigarette holder 103, thus securing the cigarette holder 103 to the second positions of the turntable 102 based on these threads.

[0035] The target shape can be a shape that matches the shape of the cigarette to be tested. The cigarette insertion port can be used to insert the filter end of the cigarette to be tested to fix the cigarette to be tested. The second position can be a position on the turntable used to fix the cigarette holder. Multiple second positions can be evenly distributed on the turntable 102. It should be noted that the multiple second positions can include the first position, and any one of the multiple second positions can be used as the first position.

[0036] Specifically, multiple threaded through holes can be provided on the turntable 102, allowing the ventilation tube of the cigarette holder 103 to be secured to the turntable via the threads. Furthermore, the filter end of the cigarette to be tested can be inserted into the cigarette insertion port of the cigarette holder 103. Further, the turntable 102 can be rotated by the turntable motor 101 according to a preset rotation angle, moving the cigarette to be tested held by the cigarette holder 103 to the first end of the smoke channel 5. Further still, after a preset rotation cycle, the turntable 102 can be rotated again by the turntable motor 101 according to a preset angle, moving the next cigarette to be tested held by the cigarette holder 103 to the first end of the smoke channel 5.

[0037] Based on the above embodiments, such as Figure 1 As shown, the flue gas passage control module 3 includes a multi-channel controller 301 and a multi-channel control valve 302. The multi-channel controller 301 communicates with the main controller 10 and outputs control signals according to a preset cycle upon receiving an automatic collection signal from the main controller 10. The multi-channel solenoid valve 302 receives the control signals and, based on the received control signals, adjusts the valve state of at least one solenoid valve to deliver the cigarette smoke drawn by the suction device 2 to the target collection container 4 based on the adjusted valve state.

[0038] The multi-channel controller 301 is a control device used to control the valve status of each solenoid valve in the multi-channel solenoid valve. The main controller 10 is the overall control device corresponding to the cigarette smoke collection device, which can be used to control the cigarette puff-by-puff smoke collection device as a whole. The main controller 10 can communicate with the multi-channel controller 301 and the smoking machine turntable 1. The automatic collection signal can be a signal that drives the cigarette puff-by-puff smoke collection device to automatically collect cigarette smoke, that is, a signal that enables the cigarette puff-by-puff smoke collection device to collect cigarette smoke in automatic mode. The preset period can be the period of changing the output port of the output control signal. It should be noted that the preset period can be the time interval between each two adjacent puffs of any one of the cigarettes to be tested. The advantage of this setup is that it allows for the extraction of cigarette smoke from at least one cigarette to be tested on the smoking machine turntable. Consequently, the cigarette smoke generated by at least one cigarette to be tested can be transported to the same target collection container 4, thus achieving the effect of allowing the smoke from multiple cigarettes to be tested to enter different target collection containers 4.

[0039] Optionally, the multi-channel controller 301 includes multiple output ports, the number of which corresponds to the number of solenoid valves, and they are one-to-one. That is, one output port controls one solenoid valve. For example,... Figure 1 As shown, assuming there are N output ports, namely output port 3011, output port 3012, output port 3013, ..., output port 301N. Correspondingly, the number of solenoid valves in the multi-way solenoid valve 302 can also be N, namely solenoid valve 3021, solenoid valve 3022, solenoid valve 3023, ..., solenoid valve 302N. Output port 3011 controls solenoid valve 3021, output port 3012 controls solenoid valve 3022, output port 3013 controls solenoid valve 3023, and so on, with output port 301N controlling solenoid valve 302N. The output ports are used to control the valve state of the solenoid valves. That is, when an output port outputs a control signal, the solenoid valve corresponding to that output port can be opened based on the control signal, while other solenoid valves remain closed.

[0040] The multi-way solenoid valve 302 may include multiple solenoid valves, each of which can control one flue gas passage. The multi-way solenoid valve 302 includes multiple flue gas passages, with one end connected to a suction device and the other end connected to a target collection container. Each flue gas passage is equipped with a solenoid valve. When the solenoid valve is in the open state, the flue gas drawn by the suction device is transported to the target collection container connected to the flue gas passage.

[0041] The first end of the flue gas passage can be the inlet of the multi-way solenoid valve 302. The second end can be the outlet of the multi-way solenoid valve 302. In this embodiment, the multi-way solenoid valve 302 has only one inlet, meaning that multiple flue gas passages share a single inlet.

[0042] Specifically, when the multi-channel controller 301 receives the automatic collection signal sent by the main controller 10, it can determine the output port for sending the control signal and output the control signal through the output port to send the control signal to the solenoid valve corresponding to the output port. Then, based on the control signal, the solenoid valve can be controlled to be in the open state, while the other solenoid valves in the multi-channel solenoid valve 302 are in the closed state. Furthermore, the cigarette smoke discharged from the suction device 2 can be transported to the target collection container 4 connected to the smoke passage through the smoke passage containing the solenoid valve. Further, after a preset period, the output port for sending the control signal can be determined again, and the control signal can be output through the output port. Then, the steps of controlling the opening and closing of the solenoid valve are executed again, and the cigarette smoke discharged from the suction device 2 is transported to the target collection container 4 connected to it through the smoke passage corresponding to the output port. Thus, the effect of delivering the smoke from at least one cigarette to different target collection containers 4 is achieved.

[0043] Optionally, the main controller 10 includes: a control button 11; the control button 11 is used to send a button signal to the multiplexer 301 so that the multiplexer 301 outputs a control signal based on the button signal.

[0044] The control button 11 can be used to control the signal output of the multiplexer 301. Optionally, the number of control buttons 11 can be the same as the number of output ports in the multiplexer 301, and they correspond one-to-one. That is, one control button 11 can be used to control one output port. When a trigger operation is detected for any control button 11, a button signal can be sent to the multiplexer 301, so that the multiplexer 301 controls the output port corresponding to the control button 11 to output a control signal based on the button signal. Alternatively, there can be only one control button 11, that is, multiple output ports can be controlled by one control button 11. The multiple output ports can be sorted according to a preset rule. When the cigarette smoke collection device is in the initial state, when a trigger operation is detected for the control button 11, a button signal can be sent to the multiplexer 301. Then, the multiplexer 301 can control the output port that is ranked first to output a control signal based on the button signal. Furthermore, if a trigger operation on control button 11 is detected again, a button signal can be sent to multiplexer 301. Then, multiplexer 301 can control the output port of the second position to output a control signal based on the button signal, and so on.

[0045] Based on the above technical solutions, the cigarette smoke collection device further includes a filter 6; wherein the filter 6 is disposed in the smoke channel 5 between the smoking machine turntable 1 and the suction device 2, and is used to filter the substances to be filtered in the cigarette smoke as the cigarette smoke flows through the smoke channel 5 to the suction device 2.

[0046] Filter 6 can be a device for filtering particulate matter in flue gas. Filter 6 can be used to filter substances from the flue gas. Optionally, filter 6 can be a Cambridge filter, which traps particulate matter in cigarette smoke without interfering with the detection of other components. The substances to be filtered can be particulate matter that needs to be filtered to avoid interference with gas analysis. Optionally, the substances to be filtered include tar and other possible solid or liquid particles generated with the flue gas.

[0047] Specifically, the cigarette to be tested is drawn in by the suction device 2, generating cigarette smoke which is then transported in the smoke channel 5. Further, as the cigarette smoke flows through the smoke channel 5 to the suction device 2, it passes through the filter 6. The filter 6 then filters the substances in the cigarette smoke, allowing the smoke channel control module to deliver the filtered cigarette smoke to the target collection container 4.

[0048] Optionally, the cigarette puff-by-puff smoke collection device further includes a filter holder; wherein the upper cover of the filter holder is fixed to the upper side of the filter through a first connecting structure, and the base of the holder is fixed to the lower side of the filter through a second connecting structure, for fixing the filter in the smoke channel.

[0049] The first connecting structure may include a boss. The second connecting structure may include a groove. Next, a specific example will be used to illustrate the overall working process of this cigarette puff-by-puff smoke collection device.

[0050] like Figure 1As shown, in the initial state of the cigarette smoke collection device, the valves of multiple solenoid valves in the multi-way solenoid valve 302 are all in the closed state. When the multi-way controller 301 receives the automatic collection signal sent by the main controller 10, it can first control the output port 3011 to output a control signal and send the control signal to the solenoid valve 3021 in the multi-way solenoid valve 302. Then, the valve state of the solenoid valve 3021 can be adjusted to the open state. Furthermore, for the smoking machine turntable 1, the turntable motor 101 can control the turntable to rotate according to preset rotation parameters, so as to move at least one cigarette stick to be tested that is in a burning state fixed on the turntable to the first end of the smoke channel 5. For at least one cigarette stick to be tested, the suction device 2 can suck the cigarette stick to be tested that has moved to the first end of the smoke channel 5. When the suction device 2 sucks the cigarette stick to be tested through the piston, the air inlet at the first end is in the open state, the air outlet at the second end is in the closed state, and cigarette smoke is obtained. Subsequently, the piston is used to expel the drawn-in cigarette smoke. During expulsion, the inlet at the first end is closed, and the outlet at the second end is open. The drawn-in cigarette smoke can then be discharged through the second end and further transported to the first end of the smoke passage in the smoke passage control module 3. This smoke is then transported through the smoke passage corresponding to solenoid valve 3021 to container 401 in the target collection container 4 corresponding to solenoid valve 3021. This allows for the collection of the first puff of smoke from at least one cigarette to be detected. Furthermore, the output port 3012 can output a control signal, which is then sent to solenoid valve 3022 in the multi-channel solenoid valve 302. This allows the valve state of solenoid valve 3022 to be adjusted to the open state, and the valve state of solenoid valve 3021 to the closed state. Furthermore, for the smoking machine turntable 1, at least one cigarette under test, currently burning, can be moved to the first end of the smoke channel 5. The smoke is then drawn in by the suction device 2, and the drawn-in cigarette smoke is discharged. The discharged cigarette smoke is then transported to the first end of the smoke channel in the smoke channel control module 3, and through the smoke channel corresponding to the solenoid valve 3022, it is transported to container 402 in the target collection container 4 corresponding to the solenoid valve 3022. This allows for the collection of the second puff of smoke from at least one cigarette under test. This process continues, resulting in puffs of smoke from at least one cigarette under test, which are then stored in different target collection containers 4. Finally, a gas analysis device can be used to analyze the collected puffs of smoke, enabling the detection of carbon monoxide and carbon dioxide concentrations in each puff of cigarette smoke.

[0051] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
