Embodiment 1

[0039] A device for real-time determination of system pressure drop changes during cigarette burning, such as figure 1 , including a cigarette holder 2, a three-way regulating valve 4, a pressure sensor 6, a signal processing module 7, a controller 8, a cigarette suction system 9, a synchronous trigger device 10 for capturing a suction signal, and a cigarette holder 2 The outlet of the pressure sensor 6 is connected to the port 1 of the three-way regulating valve 4 through the hose one 3; the input end of the pressure sensor 6 is connected to the port three of the three-way regulating valve 4 through the hose two 5, and the output end of the pressure sensor 6 is connected with the signal processing The input ends of the modules 7 are connected; the input end of the cigarette suction system 9 is connected to port 2 of the three-way regulating valve 4, the output end of the cigarette suction system 9 is connected to the input end of the synchronous trigger device 10, and the sync...

Embodiment 2

[0046] The structure of embodiment 2 is basically the same as that of embodiment 1. The difference between embodiment 2 and embodiment 1 is that the range of pressure sensor 6 is unchanged, its response frequency is 1KHz, the data acquisition frequency of signal processing module 7 is 50Hz, and the hose One 3. The sum of the volumes of the three-way regulating valve 4 and the hose two 5 is 10mL.

[0047] The pressure drop in the system when a certain brand of cigarette 1 was burned was measured by using the device and method of the present embodiment, image 3 for the measurement result. image 3 The measurement result of this cigarette 1 shows that 8 puffs of this cigarette 1 are burnt altogether, and in each puffing interval, the puffing interval is 2s in this embodiment, the maximum test value of system pressure drop is different, and the tar of cigarette 1 smoke and harmful There are also significant differences among the mouth-to-mouth releases of the ingredients, theref...

Embodiment 3

[0049] The structure of embodiment 3 is basically the same as that of embodiment 1. The difference between embodiment 3 and embodiment 1 is that the range of pressure sensor 6 is unchanged, its response frequency is 1KHz, and the data acquisition frequency of signal processing module 7 is 100Hz. 13. The sum of the volumes of the three-way regulating valve 4 and the hose 25 is 100mL.

[0050] The pressure drop in the system when a certain brand of cigarette 1 was burned was measured by using the device and method of the present embodiment, Figure 4 It is the measurement result in the third puff interval of cigarette 1 of this brand. Figure 4 The measurement results show that within the puff interval, the pressure drop of the system presents a sinusoidal trend, that is, it increases first and then decreases, which has a certain relationship with the puff parameters used by the puff system, and can also serve as a basis for further elucidation of cigarette 1 The influence of t...

Abstract

The invention provides a device and a method for determining system pressure drop change in a cigarette burning period in real time. The device comprises a cigarette clamp, a three-way control valve, a pressure sensor, a signal processing module, a controller, a cigarette suction system and a synchronous trigger device used for capturing a suction signal, wherein an outlet of the cigarette clamp is connected with a first port of the three-way control valve through a first hose, and an input end of the pressure sensor is connected with a third port of the three-way control valve through a second hose. The device can be used for realizing the real-time monitoring for the change condition of the pressure drop in the cigarette burning period, determining the pressure drop value in the system in the cigarette burning period, monitoring the change condition in the suction burning process and realizing the dynamic detection for the burning condition in the cigarette suction process, and meanwhile, the device can meet the requirements of monitoring and measuring for the pressure drop change condition in the suction system under different cigarette suction parameters and different smoke capturing modes. The device and method are wide in application scope.

Description

technical field [0001] The invention relates to a device and method for real-time measuring the change of system pressure drop during cigarette burning. Background technique [0002] After the cigarette is ignited, charcoal is generated at the head end immediately, thus forming the combustion system of the cigarette. The combustion process of the cigarette is extremely complicated, accompanied by complex physical and chemical changes, and the smoke released during the combustion process of the cigarette has been identified. There are more than 5,000 kinds in the combustion process, and there are two different combustion modes in the combustion process, suction combustion and free combustion (ie smoldering). The solid matter of the burning part forms a cone - the burning cone, and there is a black charcoal line between the burning cone and the unburned cigarette paper. When smoking, the tobacco around the bottom of the cone is burned, the charcoal line moves backward, the co...
