Description

A cigarette simulation motion and ambient airflow detection device

Technical Field

The invention belongs to the technical field of cigarette detection equipment, and in particular relates to a cigarette simulation motion and environmental airflow detection device.

Background technique

In the cigarette smoking path simulation system, the whole process of human cigarette smoking and automatic continuous detection are simulated. In order to achieve the detection environment that can simulate the environmental conditions of different outdoor air flow rates during the sample detection process, it is necessary to provide a set of integrated use, which can simulate the air flow rate and measure the quantitative value of the flow rate control at the cigarette detection position.

It is common for consumers to smoke cigarettes outdoors. Therefore, when testing and studying the index parameters of cigarette smoking and burning, providing an environment that simulates different outdoor air flow rates can make the test results more accurate and objective and improve the accuracy of dynamic measurement of cigarettes. At the same time, it can also provide testing and research conditions for cigarette burning indicators under different environmental conditions. In addition, by integrating the air sensing device into the simulated cigarette smoking system, it is also possible to collect and study the changes in air flow rate during the entire smoking process of cigarettes under different smoking environmental conditions.

Based on the above situation, it is urgent to develop a set of devices suitable for cigarette simulation movement and environmental airflow detection.

Furthermore, preferably, the axis of the cigarette holder, the axis of the cigarette and the axis of the working end of the manipulator are kept consistent.

Furthermore, preferably, the cigarette holder is fixed to the manipulator by means of threaded engagement.

Furthermore, preferably, the manipulator simulates the smoking action of a consumer in space.

Compared with the prior art, the present invention has the following beneficial effects:

The present invention uses an airflow measurement sensor installed on the connection seat to collect the air flow rate during the dynamic test of the cigarette movement at the clamping end of the manipulator, so as to realize real-time measurement of airflow during the dynamic movement. In subsequent detection, the airflow adjustment device provides the air flow rate under different environmental conditions, and calibrates the airflow conditions at the cigarette burning and smoking position obtained by real-time measurement through the matching integrated airflow measurement sensor, so as to simulate the cigarette smoking process under different environmental conditions.

Through the technology and device developed by the present invention, an environment simulating different outdoor air flow rates is provided, which makes the detection results more accurate and objective, and improves the accuracy of dynamic measurement of cigarettes. At the same time, it can also provide detection and research conditions for cigarette burning indicators under different environmental conditions. In addition, by integrating the air sensing device into the simulated cigarette smoking system, the changes in air flow rate of cigarettes during the entire smoking process under different smoking environmental conditions can also be collected and studied. The present invention is suitable for simulated motion and environmental airflow detection devices for various types of cigarettes.
