Abstract
Description
Technical Field
[0001] This utility model relates to the field of cigarette combustion cone drop detection technology, specifically a cigarette combustion cone drop detection device. Background Technology
[0002] Cigarette combustion cone drop test refers to detecting how long the combustion cone of a cigarette will fall off during the combustion process. This phenomenon usually occurs when consumers are smoking the cigarette. The cigarette combustion cone falls off due to the flicking action, which may burn clothing and pose a fire hazard, seriously affecting the sensory quality of the cigarette and the consumer's user experience.
[0003] Currently, most methods involve fixing the cigarette with a mouthpiece and allowing it to burn naturally until the combustion cone falls off. Only then is the remaining length of the cigarette measured with a measuring tape to determine the length of the combustion cone. This detection method is inefficient, cannot compare multiple sets of cigarettes for testing, and the direct emission of smoke can easily cause injury to the testing personnel, resulting in low practicality of the testing device.
[0004] This application is submitted in order to address the above issues. Utility Model Content

The cigarette combustion cone drop detection device includes a detection component 1 and a filter component 2. The detection component 1 includes a housing containing a door 101 and an infrared distance sensor 102. The door 101 is located at the front end of the detection component 1. Multiple sets of infrared distance sensors 102 are evenly arranged at the rear end of the door 101, capable of detecting the distance between the cigarette and the door 101. The filter component 2 includes a filter box containing an activated carbon filter block 201, an exhaust fan 204, and a connecting pipe 205. The activated carbon filter block 201 is located inside the filter box and can filter cigarette smoke. The exhaust fan 204 is located at the middle position of the rear end of the detection component 1. One end of the connecting pipe 205 is connected to the exhaust fan 204, and the other end of the connecting pipe 205 is also connected to the exhaust fan 204, capable of extracting smoke for filtration. A sealing cover 103 is provided at the bottom of one side of the detection component 1. A mounting plate 202 is provided at the end of the filter box away from the detection component 1, which can seal one end of the filter box and facilitate the replacement of the filter block 201. Multiple sets of air outlets 203 are provided at the top of the filter box near the detection component 1, which can allow the filtered gas to pass through.
[0042] Please refer to Figure 1 and Figure 3 The rear end of the housing is equipped with an installation component 3. The installation component 3 includes an installation block. The space between the installation block and the rear wall of the housing forms a suction chamber 301, which can store smoke. Multiple sets of installation pipes 302 are evenly distributed at the front end of the installation block. A cigarette holder 303 is provided on the outside of the installation pipe 302 to realize the installation and detection of cigarettes. The top of the housing is equipped with a fixing cover 304. A camera 305 is installed on the top of the fixing cover 304, which can record the combustion process of cigarettes.
[0043] Please refer to this carefully. Figure 1 and Figure 2The door 101 has multiple hinges on one side, and is movably connected to the body via hinges. The door 101 can be opened and closed for easy cigarette testing. Support legs are located at the four corners of the bottom of the body, providing support and ensuring stability of the testing device. The inner wall of the filter box has slots. The activated carbon filter block 201 is detachably connected to the filter box via these slots, allowing for easy replacement. The exhaust fan 204 is detachably connected to the body via bolts, allowing it to be installed at the rear of the body. The exhaust fan 204 is connected to the filter box via a connecting pipe 205, facilitating the extraction of cigarette smoke into the filter box. Support blocks are located on both sides of the bottom of the filter box. A ash discharge port is located on one side of the bottom of the body to discharge ash from inside the box. A sealing cover 103 is detachably connected to the body to seal the ash discharge port. Mounting plate 202 is detachably connected to filter box via fixing bolts, allowing for easy assembly and disassembly of the mounting plate 202 and filter box. Air inlets are located at the top of both sides of the housing to provide oxygen for cigarette combustion.
[0044] Please refer to this carefully. Figure 1 and Figure 3 A through-hole extending into the suction chamber 301 is located at the center of the rear end of the housing to facilitate smoke extraction. The mouthpiece 303 is detachably connected to the mounting block via a mounting tube 302, allowing for easy replacement. The camera 305 is detachably connected to the housing via a fixing cover 304, enabling real-time recording of cigarette combustion. An infrared distance sensor 102, corresponding to the mounting tube 302, monitors the distance between each group of cigarettes and the housing door 101 in real time, allowing for calculation of the cigarette combustion cone length.
[0045] Working Principle: Before use, a cigarette is installed in the mouthpiece 303 and lit. During use, the power is turned on, and the exhaust fan 204 generates suction, accelerating the combustion rate of the cigarette until the combustion cone falls. The distance between the cigarette and the door 101 is detected in real time by the infrared distance sensor 102, and the combustion of the cigarette is monitored in real time by the camera 305. The smoke generated by the burning cigarette enters the suction chamber 301 through the installation pipe 302, and is then transported to the inside of the filter box by the exhaust fan 204 and connecting pipe 205. The smoke is filtered by the activated carbon filter block 201 and finally discharged through the vent 302, preventing cigarette smoke from harming personnel. The combustion cone falls into the box. Removing the sealing cover 103 allows the ash to be swept from the ash discharge port, cleaning the inside of the detection device and improving its performance.
