Description

Technical Field

[0001] This utility model belongs to the field of cigarette filter rod temperature measurement, specifically relating to a real-time, multi-directional, and controllable radial puncture measurement system and method for the internal temperature of a cigarette, and more specifically to a method and system for multi-directional controllable puncture sealing measurement of filter rod temperature. The aim is to achieve real-time, multi-directional, and position-controllable measurement of filter rod temperature through a radial puncture measurement module during the smoking process, providing test data for the study of filter rod thermal stability. Background Technology

[0002] In the field of cigarette filter rod temperature measurement, current technologies still have certain limitations in accurately acquiring filter rod temperature data. Traditional measurement methods struggle to achieve real-time, multi-directional, and positionally controllable temperature measurement of the filter rod during inhalation, failing to meet the needs of in-depth research on the thermal stability of the filter rod. Some existing devices are prone to cigarette deformation or leakage during measurement, severely impacting the accuracy and reliability of the measurement results, making the acquired temperature data unable to truly reflect the thermal performance of the filter rod under normal inhalation conditions.

[0003] Most published studies on filter rod temperature measurement focus on the general monitoring of overall temperature, with relatively little research on the fine temperature distribution inside the filter rod, especially the radial temperature distribution. For example, some heating temperature measurement devices for cigarette smoking devices mainly focus on measuring the temperature of the heating rod, using elastic pre-tightening mechanisms to ensure close contact between the temperature sensing element and the heating rod, but lack specific design for multi-directional, positionally controllable measurement of the filter rod's temperature. Some cigarette filter rod heating and shaping devices also emphasize achieving heating and shaping effects through various structural designs, such as preventing water vapor corrosion within the equipment and enhancing heat utilization, without addressing the effective measurement of the filter rod temperature during smoking.

[0004] In the tobacco and related filter rod applications, temperature changes during the smoking process significantly impact the performance and quality of the filter rod. However, the market currently lacks a method and device capable of accurately achieving multi-directional controllable puncture sealing and precise, real-time temperature measurement of the filter rod. This technological gap hinders the industry's in-depth exploration of the dynamic temperature characteristics of filter rods during smoking, thus limiting the optimization and upgrading of filter rod products. Therefore, developing high-precision filter rod temperature measurement methods and devices has become a pressing research focus for those skilled in the art.

[0005] To address the above problems, this utility model is proposed. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a radial puncture measurement module for cigarette temperature. Its unique method and system for measuring filter rod temperature through multi-directional controllable puncture sealing can achieve real-time, multi-directional, and position-controllable measurement of filter rod temperature by using the radial puncture measurement module during the smoking process, providing key test data for the study of filter rod thermal stability.

[0007] This utility model belongs to the field of cigarette filter rod temperature measurement, specifically relating to a method and system for multi-directional controllable puncture and sealing measurement of filter rod temperature. The system device achieves real-time, multi-directional, and position-controllable measurement of filter rod temperature through a radial puncture measurement module during the smoking process.

[0014] The automatic sealing unit is used to automatically seal the puncture channel after puncture to prevent smoke leakage.

[0015] Preferably, the real-time, multi-directional, and controllable radial puncture measurement system for the internal temperature of the cigarette includes three sets of puncture measurement sensor devices, and the three sets of puncture measurement sensor devices are independent of each other. The spatial layout of the three sets of puncture measurement sensor devices is 120° rotationally symmetrically distributed around the circumference of the cigarette to achieve multi-directional and multi-point synchronous measurement.

[0016] Preferably, the force feedback unit adjusts the puncture speed through closed-loop control to avoid damage to the cigarette structure.

[0017] Preferably, the temperature detection unit includes a radial temperature puncture probe for real-time measurement of the temperature of the smoke inside the cigarette stick;

[0022] Preferably, the suction device is used to simulate the smoking process of a cigarette in real time.

[0023] Preferably, the cigarette removal device is used to remove the cigarette from the smoking device after the test is completed.

[0024] Preferably, the real-time, multi-directional, and controllable radial puncture measurement system for the internal temperature of the cigarette also includes a wind hood. The wind hood is located around the test cigarette, forming a wrap-around cover, which can create a preset airflow environment around the cigarette and reduce the escape of smoke.

[0025] Preferably, the real-time, multi-directional, and controllable radial puncture measurement system for the internal temperature of the cigarette also includes an ash tray, which is located below the cigarette and is designed in a flat shape so that the ash can be easily poured out after smoking.

These three probes simultaneously monitor the temperature at a position between 12-50mm from the cigarette filter rod end face. The three radial temperature puncture probes can monitor the same distance from the filter rod end face or different distances from the cigarette butt end face. The radial puncture measurement temperature range is 0–550℃, resolution is 0.1℃, and measurement accuracy is ±2.0℃. The radial puncture measurement component has a detection range. Specifically, the needle part of radial temperature puncture probe 2 (6) (the sealing method of radial temperature puncture probes 1 and 3 is the same as that of radial temperature puncture probe 2) is designed with an elastic sealing sleeve. When the needle of radial temperature puncture probe 2 (6) is inserted into the cigarette filter rod, the elastic sealing sleeve contracts, automatically tightening and sealing the area. Specifically, the hood 2 forms a wraparound cover around the cigarette, creating a pre-defined airflow environment around it and reducing smoke escape. Furthermore, the entire device also features a large hood, similarly designed to create a pre-defined airflow environment around the cigarette and reduce smoke escape. The ashtray 3, located below the cigarette, is designed in a flat shape for easy emptying of ash after smoking.

[0034] Step 5: The cigarette removal device retracts the cigarette, completing the temperature monitoring of the cigarette filter rod.

[0035] Specifically:

[0036] Step 1: Radial temperature puncture probes 1 and 4, 2 and 6, and 3 and 1 move forward under the drive of linear motors in the front and rear directions, respectively. After moving to the pre-set position, radial temperature puncture probes 1 and 4, 2 and 6, and 3 and 1 are retracted towards the cigarette butt axis under the drive of circumferential linear motors, inserted into the cigarette filter rod, and reach the measurement position, ready for monitoring.
