Abstract
The invention discloses a device and a method for measuring the gas phase temperature of a cigarette combustion cone, which belong to the technical field of cigarette tests. The device is provided with a synchronous triggering device and a data acquisition card; a suction signal indication output end of a smoking machine is connected with an input end of the synchronous triggering device, and an output end of the synchronous triggering device is connected with a computer control system through an RS232 interface; and an output end of a thermocouple temperature measuring system provided with agroup of thermocouples is connected with an input end of the data acquisition card, and an output end of the data acquisition card is connected with the computer control system through a USB interface. The method for measuring the gas phase temperature of the cigarette combustion cone realizes automatical acquisition in synchronization with suction and realizes that software starts to acquire temperature data automatically at the same time of lighting the cigarette. Data of each independent experiment are ensured to be aligned on a time axis, and an automatic stop function of setting the acquisition time is realized. The instrumental automatic level is improved.
Description
technical field [0001] The invention belongs to the technical field of cigarette testing, in particular to a device for measuring the gas phase temperature of a cigarette burning cone and a method for measuring the gas phase temperature of a cigarette burning cone. Background technique [0002] In the prior art, during the combustion process of cigarettes, a combustion cone is formed, and the temperature of the combustion cone and the distribution of the temperature field are one of the important parameters affecting the quality of cigarettes and the reduction of tar and harm. In order to realize the monitoring of the temperature field distribution of the cigarette burning process, a smoking machine is generally used to simulate the smoking process, and at the same time, a cigarette burning cone temperature measuring instrument is used to measure the temperature information of the cigarette during the burning process. The temperature of the cigarette burning cone includes so...
