[0037] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to specific embodiments.

[0038] Example 1

[0039] like Figure 1 , Figure 2 As shown, this utility model provides a high-precision multi-parameter cigarette measuring device, including a measuring head 1 and a negative pressure generating device 2 connected to the measuring head; the measuring head 1 includes an open end and a closed end, and a detection chamber for mounting the cigarette to be tested is provided inside; the detection chamber is divided axially into a paper ventilation chamber 11, a mouthpiece ventilation chamber 12, and a suction resistance chamber 13, such that when the cigarette to be tested 100 is installed in the detection chamber, its cigarette paper section and filter section are located in the paper ventilation chamber 11 and the mouthpiece ventilation chamber 12 respectively, and the suction resistance chamber 13 is located at the closed end of the measuring head 1; and when the cigarette to be tested 100 is installed in the detection chamber, the paper ventilation chamber 11... The mouth ventilation chamber 12 and the suction resistance chamber 13 are isolated from each other. The paper ventilation chamber 11, mouth ventilation chamber 12, and suction resistance chamber 13 are respectively connected to the paper ventilation detection component, the mouth ventilation detection component, and the suction resistance detection component. During the test, the airflow passes sequentially through the paper ventilation detection component, the paper ventilation chamber 11, the suction resistance chamber 13, and the negative pressure generating device 2 for the detection of paper ventilation rate; the airflow passes sequentially through the mouth ventilation detection component 5, the mouth ventilation chamber 12, the suction resistance chamber 13, and the negative pressure generating device 2 for the detection of mouth ventilation rate; the airflow passes sequentially through the paper ventilation chamber 11, the suction resistance chamber 13, the suction resistance detection component, and the negative pressure generating device 2 for the detection of suction resistance. Furthermore, during the paper ventilation rate detection, mouth ventilation rate detection, and suction resistance detection, the airflow passes through the cigarette to be tested from the opening end of the measuring head 1 and enters the suction resistance chamber 13.

After loading the cigarette 100, the airflow is detected by a paper ventilation detection component connected to the paper ventilation chamber 11, thus determining the ventilation rate of the cigarette paper. Similarly, the airflow is detected by a mouthpiece ventilation detection component connected to the mouthpiece ventilation chamber 12, thus determining the ventilation rate of the filter. After the airflow passes through the cigarette 100, the pressure in the air path is detected by a suction resistance detection component. The suction resistance of the cigarette can be calculated based on the pressure change compared to when unloaded. The three detection systems each perform their respective functions, can be activated simultaneously without interference, thus achieving the goal of simultaneously detecting three parameters.
