Description

Technical Field

[0001] The invention belongs to the technical field of cigarette detection devices, and in particular relates to a multi-cigarette simulated smoking detection device. Background Art

[0002] With the development of society and economy, consumers' pursuit of cigarette quality is no longer limited to the material and craftsmanship of the cigarettes themselves. More importantly, the specific ingredients of cigarettes, the aroma of cigarettes, the taste of cigarettes, etc. are also receiving much attention. Therefore, cigarette smoke detection and evaluation has become an important part of the cigarette production process.

[0003] There are two main evaluation methods in the current market. One is traditional manual evaluation, which is to randomly select workers engaged in cigarette production or consumers who like cigarettes, and obtain the taste, aroma, burning time, etc. of the cigarettes during the smoking process by manually smoking cigarettes. However, this evaluation method is greatly influenced by subjective factors, has high labor costs, one person can only taste and smoke one cigarette at a time and cannot be processed in batches, and the human body has no significant perception of cigarette smoke components. The second is to use a series of experimental methods to test the smoke collected by the smoke suction device using test papers, solutions, filters and other experimental materials to obtain data results. However, this detection method can usually only detect a single smoke component or a certain type of smoke component, and the smoke suction device used can usually only smoke and collect smoke from a single cigarette, which has problems such as low detection efficiency, cumbersome steps and high costs. Summary of the invention

[0007] It is further defined that the suction mechanism includes a first servo motor fixedly connected to the inner wall of the box body, the output shaft end of the first servo motor is fixedly connected to a gear, the end face of the gear away from the first servo motor is rotatably connected to a transmission rocker, the end of the transmission rocker away from the gear is rotatably connected to a connecting rod, the end of the connecting rod away from the transmission rocker is fixedly connected to a piston, and the piston is slidably connected in the smoke inlet pipe. The first servo motor drives the gear at the end of its output shaft to rotate, and then drives the transmission rocker connected to the gear to perform periodic motion, so that the transmission rocker drives the connecting rod to perform linear reciprocating motion, and finally drives the piston to perform piston motion in the smoke inlet pipe, so as to achieve the purpose of negative pressure smoke extraction.

[0008] It is further defined that the smoke detection mechanism includes a carbon monoxide electrochemical sensor, a nitrogen oxide electrochemical sensor, an ammonia compound electrochemical sensor, a hydrogen cyanide electrochemical sensor, an ethylene oxide electrochemical sensor, and a propylene oxide electrochemical sensor, which are sequentially installed in the detection tube, and a controller is provided on the outer wall of the box body, and the controller is electrically connected to the carbon monoxide electrochemical sensor, the nitrogen oxide electrochemical sensor, the ammonia compound electrochemical sensor, the hydrogen cyanide electrochemical sensor, the ethylene oxide electrochemical sensor, the propylene oxide electrochemical sensor, and the first servo motor.

The controller also has the function of controlling the working state of the first servo motor, such as the motor speed, rotation direction, and working time.

[0009] It is further defined that the smoke capture mechanism comprises an annular frame, the outer diameter of the annular frame is the same as the outer diameter of the detection tube, a rubber clamp ring is fixedly connected to the annular frame, and a Cambridge filter is clamped in the rubber clamp ring;

[0010] The pipe wall of the detection pipe is provided with an installation groove, and the smoke capture mechanism is installed in the installation groove;

[0011] The outer wall of the detection tube is clamped with an arc-shaped thin plate covering the smoke capture mechanism, and the thin plate includes a sealing layer close to the detection tube and a first shaping layer away from the detection tube. The Cambridge filter is clamped by an annular frame and a rubber clamp ring, and then the smoke capture mechanism is detachably clamped in the installation groove of the detection tube.

[0037] like Figure 4 As shown, the smoke extraction mechanism includes a lotus-shaped diverter 41 detachably mounted on the lower end of the detection tube 22, and four evenly distributed air outlets 42 extend from the lower end of the diverter 41. The air outlets 42 are connected to smoke outlet pipes 43 of the same length and shape. Four triangular flasks 44 are placed on the inner bottom surface of the detection box 3. The triangular flasks 44 are filled with extraction solutions of different types and the same volume. The lower end of the smoke outlet pipe 43 is placed in the triangular flask 44, and the placement height of the lower end of the smoke outlet pipe 43 is the same as the height of the solution in the triangular flask 44.

[0038] like Figure 7 As shown, the first one-way valve 19 and the second one-way valve 21 have the same structure. The first one-way valve 19 includes a baffle ring 1901 whose outer diameter is equal to the inner diameter of the smoke inlet pipe 4. A circular baffle plate 1902 is hinged on the right side of the baffle ring 1901. The diameter of the baffle plate 1902 is larger than the inner diameter of the baffle ring 1901 and smaller than the outer diameter of the baffle ring 1901. A pressure plate 1903 is laterally fixedly connected to the right side of the baffle plate 1902. A micro spring 1904 is arranged between the bottom of the pressure plate 1903 and the inner wall of the smoke inlet pipe 4.

[0039] like Figure 1 As shown, an alarm 45 is provided on the top of the box 3 , and a controller 46 is provided on the front of the outer wall of the box 3 . The controller 46 is electrically connected to all electrochemical sensors, the first servo motor 23 , the second servo motor 16 , the heating resistor 13 , and the alarm 45 .

[0040] The controller 46 includes an A / D converter for data result conversion, a timer for time control, a memory for storing data, a display screen for data display, a line interface required for exporting data, a signal transceiver for sending and receiving instructions, a key panel for manual input of control instructions, and a program for implementing the above contents.

[0041] Before use, the operator is required to provide 8 cigarettes as experimental products. When the device is started for the first time, the operator is required to record the entire duration of the experimental process through the controller 46. After the smoke is sucked and detected, the operator turns off all servo motors, electrochemical sensors and heating resistors 13 through the controller 46 to stop the device and record the duration required for this operation, which is used as the preset duration for each subsequent operation of the device. Different sizes of cigarettes can be used for different experiments, and the controller 46 records and sets different preset durations according to their actual working durations.

[0042] The method of using this embodiment is as follows:

[0043] In the use of this embodiment, the triangular flask 44 and the smoke capture mechanism are first taken out, and the required extraction solution is placed in the triangular flask 44 for standby use. At the same time, artificial saliva is added to the water injection box 17 to gradually soak the entire water absorption layer 14. Then, eight cigarettes 47 are clamped in the rubber ring 7 in sequence. There is elastic potential energy between the rubber ring 7 and the clamped cigarettes 47, which can better ensure the stability of the cigarettes 47 and the sealing between the cigarettes 47 and the fixed plate 1. At the same time, the rubber rings 7 of different sizes can be replaced to facilitate the adaptation to cigarettes 47 of different sizes.

[0044] Then the first servo motor 23 is turned on, and the first servo motor 23 drives the gear 24 at the end of its output shaft to rotate, thereby driving the transmission rocker 25 connected to the gear 24 to perform periodic motion, so that the transmission rocker 25 drives the connecting rod 26 to perform linear reciprocating motion, and finally drives the piston 27 to perform piston motion in the smoke inlet pipe 4. When the piston 27 moves in the direction away from the first one-way valve 19, negative pressure suction is generated on the pipeline between the piston 27 and the first one-way valve 19, and the baffle 1902 of the first one-way valve 19 flips backwards in this case. , and then a gap appears between the baffle 1902 and the baffle ring 1901, and the gas in the cigarette chamber 2 enters the smoke inlet pipe 4. When the piston 27 moves in the other direction, the baffle 1902 of the first one-way valve 19 is pushed, and under the action of the spring, the baffle 1902 is reset and completely covers the gap between the baffle 1902 and the baffle ring 1901, so that a closed space is formed between the first one-way valve 19 and the piston 27, and then the gas in the smoke inlet pipe 4 is pushed to the gas delivery pipe 20, so as to achieve the purpose of negative pressure drawing out the gas in the cigarette chamber 2 and pushing it to the gas delivery pipe 20;

[0045] The above state is maintained for 5-10 seconds, and the air and non-target gas in the cigarette bin 2 and all pipes are exhausted. Then, the cigarette 47 is lit, the heating resistor 13 and the second servo motor 16 are turned on, and the smoke is filled in the cigarette bin 2 and each pipe. Then, a triangular bottle 44 containing an extraction solution is placed at the outlet of the smoke outlet pipe 43, a smoke capture mechanism is installed in the installation slot 37, and all electrochemical sensors are turned on to start detection. During this process, the heating resistor 13 always keeps the temperature in the cigarette bin 2 at a preset state, and the water absorption layer 14 soaked in artificial saliva keeps the humidity and chemical composition of the cigarette bin 2 similar to those of the human oral cavity, simulating the oral environment of a real person smoking a cigarette 47;

[0046] The flue gas flows from the gas transmission pipe 20 to the detection pipe 22. During the flow of the flue gas in the detection pipe 22, the concentration of common important components in the flue gas is detected by several different electrochemical sensors. In this process, the data results of the electrochemical sensors are received and displayed by the controller 46. After passing through each electrochemical sensor, the flue gas flows to the Cambridge filter 36. The Cambridge filter 36 separates the particulate matter of the flue gas. The separated gas phase continues to flow to the diverter 41. Four gas outlets 42 extend from the diverter 41. The flue gas is evenly discharged into the triangular flask 44 through the uniform gas outlets 42 and the smoke outlet pipes 43 of the same length and shape, so that the extraction and detection results can restore the actual proportion of the components to be detected in the flue gas as much as possible.

[0047] When the cigarette 47 is completely burned out, the device continues to operate the above process for 5-15 seconds to extract the smoke remaining in the cigarette bin 2 and each pipe. When this task is completed and the preset working time of the device is reached, the controller 46 controls the alarm 45 to turn on, reminding the operator to save the test data, take out the Cambridge filter 36 and the triangular flask 44 for separate testing, and remove the burnt cigarette butts to prepare for the next batch of cigarettes 47 to be tested.

[0048] The above is a detailed introduction to a multi-cigarette simulated puffing detection device provided by the present invention. The description of the specific embodiment is only used to help understand the method and core idea of ​​the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
