Detailed Implementation
[0018] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.
[0019] like Figure 1-3As shown, a device for rapidly capturing flue gas includes: a housing 1, and a flue gas collection pipe I 201, a flue gas collection pipe II 202, a flue gas collection pipe III 203, an exhaust fan 5, a collection box I 6, a collection box II 7, and a processor 8 disposed in the housing 1; the flue gas collection pipes I 201, II 202, and III 203 are placed vertically in the housing 1 and are connected to the air inlet of the exhaust fan 5 through a four-way pipe 3. A solenoid valve I 101 is disposed on the air inlet of the exhaust fan 5, and the air outlet of the exhaust fan 5 is connected to the collection box I 6 and the collection box II 7 through a three-way pipe 4 respectively. Solenoid valves II 102 and III 103 are disposed on the pipes connecting the collection box I 6 and the collection box II 7 respectively. The processor 8 is connected to the exhaust fan 5, solenoid valve I 101, solenoid valve II 102, and solenoid valve III 103. The processor 8 is a PLC controller. The structures of the smoke-collecting pipes I 201, II 202, and III 203 are similar, with the following similarities: they are all hollow inside, with a rubber plug 206 for clamping the cigarette at the top, a smoke outlet 207 at the bottom, and a magnetic cover 205 hinged to the top. The magnetic cover 205 has a magnetic strip on its end face and can close the top. The difference is that the diameter of the rubber plug 206 inside the smoke-collecting pipes I 201, II 202, and III 203 increases sequentially. During the experiment, cigarettes of different specifications can be placed into the corresponding cigarette holder (open the magnetic cover 205 and insert the cigarette into the rubber stopper 206). After the cigarette is lit, the control valve 101 is opened and the exhaust fan 5 is driven to transport the smoke. The smoke collection box I6 or collection box II7 is detected by controlling the solenoid valve II 102 and the solenoid valve III 103 to complete the collection, detection and analysis of tobacco smoke.
[0020] In this application, a Cambridge filter is installed in the collection box I6, and several interconnected reagent bottles for holding detection solutions are installed in the collection box II7. By controlling the on / off state of solenoid valve II102 and solenoid valve III103, different detection methods can be performed on the flue gas as needed.
[0021] In this application, the air inlet of the exhaust fan 5 is connected to a smoke collection pipe IV 204 via a flexible hose. A solenoid valve IV 104 is installed on the flexible hose and is connected to the processor 8. By using the flexible hose, the smoke collection pipe IV can be placed horizontally and connected to an external cigarette heater. By closing the magnetic caps 205 on the smoke collection pipes I 201, II 202, and III 203, and controlling the exhaust fan 5 and the solenoid valve 104, the smoke can be delivered to the collection box I 6 or the collection box II 7 to detect heated non-combustible cigarettes.
[0022] In this application, the exhaust fan 5 includes an impeller and a variable frequency motor. The impeller is driven by the variable frequency motor to transport gas, which can simulate the human suction frequency and better complete the experiment.
[0023] In this application, a touch screen 9 is also provided on the housing 1, and the touch screen 9 is connected to the processor 8. By writing a host computer program, the experimenter can control the experiment through the touch screen 9 and better complete the testing experiment.
[0024] The advantages of this utility model solution are:
[0025] This invention, by incorporating smoke collection pipes I 201, II 202, and III 203, can accommodate the testing of cigarettes of different specifications. Furthermore, by including smoke collection pipe IV 204, it can be connected to an external cigarette heater to detect heated non-combustible cigarettes. This effectively solves the problem of equipment limitations in laboratory smoke analysis, and facilitates the completion of tobacco smoke collection, detection, and analysis.
[0026] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model, and are not intended to limit it. Although the present utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the protection scope of the present utility model.
