Description

Technical Field

[0001] The invention belongs to the technical field of detection devices, and in particular relates to a device for rapid detection, capture and extraction of simulated smoking gas from cigarettes. Background Art

[0002] With the development of the times, people are paying more and more attention to the quality of cigarettes, and the evaluation points of cigarettes are no longer limited to the material of the cigarettes themselves and personal feelings. More people are focusing on the different audiences of cigarettes, the aroma of cigarettes, the composition of smoke, etc.

[0003] In the past, there were usually two main types of cigarette evaluation methods. The first was traditional manual smoking, in which employees or ordinary consumers in the cigarette factory were randomly selected to smoke the cigarettes to be tested. The smokers' feelings were then recorded and compared in detail to obtain the results. This method has problems such as relatively subjective data results, high labor costs, and the human body's inability to judge the specific smoke components of cigarettes. The second is to use cumbersome experimental methods to test the collected smoke samples through test paper, solutions, filters and other experimental equipment. Usually, a test experiment can only detect a single smoke component or a certain category of smoke components. There are problems such as low detection efficiency, cumbersome procedures, and high costs. Summary of the Invention

[0004] The purpose of the present invention is to provide a rapid detection and capture extraction device for simulated inhaled gas from cigarettes, which is used to solve the problems of low detection efficiency, waste of human resources, complicated steps and high cost in the existing background technology.

[0005] In order to achieve the above technical objectives, the technical solutions adopted by the present invention are as follows:

[0006] A device for rapid detection, capture and extraction of simulated inhaled gas from cigarettes, comprising a smoke inlet pipe, a detection pipe, a smoke detection mechanism, a smoke capture mechanism, a smoke extraction mechanism and a detection box;

[0007] The smoke inlet pipe is arranged in the detection box, the detection tube is connected to the pipe wall of the smoke inlet pipe located in the detection box, the smoke detection mechanism and the smoke capture mechanism are installed in the detection tube, and 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;

[0008] A controller is provided on the outer wall of the detection box, 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, and the propylene oxide electrochemical sensor.

[0009] The invention further defines a first one-way valve disposed within the smoke inlet pipe, a suction mechanism mounted on the portion of the smoke inlet pipe located within the detection chamber, the suction mechanism comprising a piston slidably connected within the smoke inlet pipe, an end of the piston remote from the first one-way valve being rotatably connected to a reciprocating mechanism, the detection pipe communicating between the first one-way valve and the piston, and a second one-way valve disposed between the end of the detection pipe proximal to the smoke inlet pipe and the carbon monoxide electrochemical sensor. The reciprocating mechanism drives the piston to move back and forth within the smoke inlet pipe, thereby achieving a negative pressure suction function for the smoke to be detected in cooperation with the two one-way valves.

[0010] The invention further defines that the reciprocating mechanism includes a servo motor disposed within the inner wall of the detection chamber, the distal end of the servo motor's output shaft being fixedly connected to a shaped rotating rod, the shaped rotating rod being rotatably connected to a driving rocker, the end of the driving rocker remote from the shaped rotating rod being rotatably connected to a piston, and the servo motor being electrically connected to a controller. The controller controls the operation of the servo motor, thereby driving the shaped rotating rod to rotate, which in turn drives the driving rocker to perform periodic motion, thereby achieving linear reciprocating motion of a piston rotatably connected to the driving rocker and located within the smoke inlet pipe.

[0011] It is further defined that the smoke capture mechanism includes 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;

[0012] A mounting groove is provided on the pipe wall of the detection tube, and the smoke capture mechanism is installed in the mounting groove;

[0013] The outer wall of the detection tube is clamped with a curved thin plate that covers the smoke capture mechanism. This plate comprises a rubber sealing layer close to the outer wall of the detection tube and a highly resilient plastic layer further away from the outer wall. The Cambridge filter is clamped by an annular frame and a rubber clamping ring. The smoke capture mechanism is then removably clamped into the mounting slot of the detection tube. The curved thin plate ensures that the smoke capture mechanism remains stable and resists falling off, making it easy to remove and replace the Cambridge filter during use.

[0014] The invention further specifies that the flue gas extraction mechanism includes a lotus-shaped diverter mounted at the end of a detection tube, the end of the diverter extending from a plurality of evenly distributed air outlets, each of which is connected to a smoke outlet pipe of the same length and shape. The inner bottom surface of the detection box is provided with a plurality of triangular flasks, the ends of the smoke outlet pipes being placed within the triangular flasks at a height equal to the height of the solution within the triangular flasks. The evenly distributed air outlets and smoke outlet pipes of the same length and shape allow the flue gas to be evenly discharged into the triangular flasks, thereby ensuring that the test results accurately reflect the actual proportion of the component to be tested in the flue gas.

[0015] The invention further defines that an alarm is provided on the top of the detection box, and the alarm is electrically connected to the controller. The working time of the device is determined by the time preset by the controller, and after the device completes the work, the controller controls the alarm to sound an alarm, thereby realizing automatic supervision of the device's work process.

[0016] It is further defined that the controller includes an A / D converter for data conversion, a processor for data processing, a display screen for displaying data, a memory for storing data, a line interface required for exporting data, a signal transceiver for sending and receiving instructions, and a key panel for manually inputting control instructions. 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, and the propylene oxide electrochemical sensor are all electrically connected to the A / D converter, and the A / D converter, display screen, memory, line interface, signal transceiver, and key panel are all electrically connected to the processor.

[0017] The invention adopting the above technical solution has the following advantages:

[0018] 1. The present invention uses a smoke detection mechanism, a smoke capture mechanism, and a smoke extraction mechanism to capture, extract, and detect various components of smoke from the same smoke source within the same work process, thereby improving work efficiency;

[0019] 2. The smoke detection mechanism of the present invention uses electrochemical sensors, controllers, alarms and other electromechanical equipment to enhance the sensitivity and objectivity of smoke component detection while also automating the detection process, thereby improving the efficiency and objectivity of smoke gas detection and reducing labor costs.

[0020] 3. The present invention uses the solution in the conical flask to perform extraction pretreatment on gas components that cannot be detected by conventional electrochemical sensors, providing samples for the detection of special gas components, avoiding the use of a large number of flue gas samples for the detection of a single gas component, simplifying the flue gas detection steps and reducing the cost of flue gas samples and equipment used for detection.

DETAILED DESCRIPTION

[0027] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that in the drawings or descriptions, similar or identical parts are numbered the same. Implementations not shown or described in the drawings are forms known to those of ordinary skill in the art. In addition, directional terms mentioned in the embodiments, such as "upper," "lower," "top," "bottom," "left," "right," "front," and "back," are merely references to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0028] like Figures 1 to 4 As shown, a device for rapid detection and capture and extraction of simulated inhaled gas from cigarettes of the present invention comprises a smoke inlet pipe 1, a detection pipe 2, a smoke detection mechanism, a suction mechanism, a smoke capture mechanism, a smoke extraction mechanism, a detection box 3, and a transparent detection box door 4;

[0029] The left end of the smoke inlet pipe 1 is connected with a gas collecting tank 5, the right side part of the smoke inlet pipe 1 is passed through the detection box 3, the right side part of the pipe of the smoke inlet pipe 1 is connected with the suction mechanism located in the suction box, the smoke inlet pipe 1 is connected with a detection tube 2 on the pipe wall inside the detection box 3, a smoke detection mechanism is installed in the detection tube 2, and a smoke extraction mechanism is connected to the lower end of the detection tube 2. A first one-way valve 6 is also provided in the smoke inlet pipe 1, and a second one-way valve 7 is also provided in the detection tube 2. The detection tube 2 is located between the first one-way valve 6 and the suction mechanism, and the detection box door 4 is hinged on the front wall of the detection box 3; through the cooperation of the suction mechanism and the smoke inlet pipe 1, the smoke outside the detection box 3 is sucked into the smoke inlet pipe 1, and the smoke between the first one-way valve 6 and the second one-way valve Under the action of the valve 7, the flue gas is pushed into the detection tube 2, in which a carbon monoxide electrochemical sensor 13, a nitrogen oxide electrochemical sensor 14, an ammonia compound electrochemical sensor 15, a hydrogen cyanide electrochemical sensor 16, an ethylene oxide electrochemical sensor 17 and a propylene oxide electrochemical sensor 18 are installed, which are used to detect the concentration of important gas components in the flue gas. Then the flue gas flows through the flue gas capture mechanism, and the gas phase and the particulate phase of the flue gas are separated by the Cambridge filter 8. The particulate phase adheres to the Cambridge filter 8, and the gas phase is sampled by the flue gas extraction mechanism, and then the equipment loaded with the particulate phase and the gas phase are taken out and tested separately. Finally, multiple data are synthesized into the test results.

[0030] The smoke capture mechanism includes an annular frame 19 that is clamped on the detection tube 2. The outer diameter of the annular frame 19 is the same as the outer diameter of the detection tube 2. A rubber clamp ring 21 is fixedly connected to the annular frame 19. The rubber clamp ring 21 clamps the Cambridge filter 8. The pipe wall of the detection tube 2 is provided with an installation groove 22. The smoke capture mechanism is installed in the installation groove 22. The outer wall of the detection tube 2 clamps an arc-shaped thin plate 24 covering the smoke capture mechanism. The thin plate 24 includes a rubber sealing layer 25 close to the detection tube 2 and a high-toughness plastic layer 26 away from the detection tube 2; the Cambridge filter 8 is clamped by the annular frame 19 and the rubber clamp ring 21, and the Cambridge filter 8 mechanism is detachably installed in the installation groove 22 of the detection tube 2, so as to facilitate the removal and replacement of the Cambridge filter 8 during the use of the device.

[0031] The suction mechanism includes a servo motor 9 fixedly connected to the inner wall of the detection box 3, and a piston 10 slidably connected to the pipe on the right side of the smoke inlet pipe 1. The piston 10 is loosely matched with the inner wall of the smoke inlet pipe 1. The right side of the piston 10 is rotatably connected to a transmission rocker 11, and the right end of the transmission rocker 11 is rotatably connected to a special-shaped rotating rod 12. The special-shaped rotating rod 12 is fixedly connected to the output shaft of the servo motor 9; the servo motor 9 drives the piston 10 in the smoke inlet pipe 1 to move, thereby realizing negative pressure suction of the cigarette smoke outside the detection box 3.

[0032] The flue gas extraction mechanism includes a lotus-shaped diverter 27 installed at the end of the detection tube 2. Four evenly distributed air outlets 28 extend from the end of the diverter 27. The air outlets 28 are connected to smoke outlet pipes 29 of the same length and shape. Four triangular flasks 30 are placed on the bottom of the detection box 3. The triangular flasks 30 are filled with extraction solutions of different types and the same volume. The ends of the smoke outlet pipes 29 are placed in the triangular flasks 30, and the placement height of the ends of the smoke outlet pipes 29 is the same as the height of the solution in the triangular flasks 30. Through the uniform air outlets 28 and the smoke outlet pipes 29 of the same length and shape, the flue gas is evenly discharged into the triangular flasks 30, so that the test results can restore the actual proportion of the component to be tested in the flue gas as much as possible.

[0033] A controller 31 is mounted on the outer wall of the test box 3, and an alarm 32 is mounted on the top of the test box 3. The controller 31 is electrically connected to the alarm 32, the servo motor 9, and all sensors. The controller 31 enables automated control of the device's workflow and data collection. After a single operation of the device is completed, the alarm 32 is controlled to sound an alarm, reminding the operator to retrieve the rapid test results.

[0034] The controller 31 includes an A / D converter for data result conversion, a timer for time control, a memory for storing data, a display screen 20 for data display, a line interface required for exporting data, a signal transceiver for sending and receiving instructions, a key panel 23 for manual input of control instructions, and a program for implementing the above contents.

[0035] Before use, this embodiment requires the operator to provide a transparent gas collecting tank 5 for easy observation for use in the experiment. 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 31. The smoke detection process can be observed through the transparent detection box door 4 and the gas collecting tank 5 during the entire operation of the device. After the smoke detection is completed, the operator turns off the servo motor 9 through the controller 31 to stop the device and record the time required for this operation, which is used as the preset duration for each subsequent operation of the device.

[0036] The method of using this embodiment is as follows:

[0037] During use of this embodiment, the operator first connects the gas collecting tank 5 to the smoke inlet pipe 1, and then turns on the servo motor 9 through the controller 31. At this time, the servo motor 9 drives the special-shaped rotating rod 12 located at the end of the output shaft of the servo motor 9 to perform a circular motion, thereby driving the transmission rocker 11 connected to the special-shaped rotating rod 12 to perform a reciprocating periodic motion, thereby causing the piston 10 to perform a piston motion in the smoke inlet pipe 1. Under the cooperation of the servo motor 9, the piston 10 and the two one-way valves, the smoke to be tested is negatively sucked into the detection box 3 and pushed toward the detection tube 2. This process lasts for 3-10 seconds, the purpose of which is to eliminate air and non-target gases in the smoke inlet pipe 1 and the detection tube 2.

[0038] After completing the above steps, the controller 31 is used to suspend the operation of the servo motor 9. The operator opens the detection box door 4 and places the triangular flask 30 containing the extraction solution under the smoke outlet pipe 29. After the placement is completed, the controller 31 is used to start the servo motor 9 and all electrochemical sensors again.

[0039] At this time, the flue gas to be tested, under the operation of the piston 10 and the cooperation of the two one-way valves, flows from the gas collecting tank 5 through the smoke inlet pipe 1 and enters the detection tube 2 by means of negative pressure suction. The six electrochemical sensors in the detection tube 2 respectively detect the concentration of the corresponding chemical components and send the real-time data to the controller 31 for display and storage. After passing through the pipe section where the electrochemical sensors are located, the flue gas continues to flow to the Cambridge filter 8. The particulate matter in the flue gas will adhere to the Cambridge filter 8. The flue gas then passes through the diverter 27 and flows evenly from the smoke outlet pipe 29 to the triangular flask 30 containing the extraction solution for extraction.

[0040] The above process is continued. When the device working time reaches the preset time, the controller 31 automatically controls the servo motor 9 to turn off and stop the data collection of the electrochemical sensor. Then, the alarm 32 is controlled to emit light and sound to remind the operator to record the detection data of the electrochemical sensor and take out the Cambridge filter 8 and the conical flask 30 for separate testing.

[0041] The above describes in detail the device for rapid detection, capture, and extraction of simulated cigarette inhalation gases provided by the present invention. The description of the specific embodiments is intended only to facilitate understanding of the present invention's method and core concepts. It should be noted that those skilled in the art will readily appreciate that various improvements and modifications to the present invention can be made without departing from the principles of the present invention, and such improvements and modifications fall within the scope of protection of the claims.
