Description

Technical Field

[0001] This application relates to the field of tobacco detection equipment technology, and in particular to a soot collection device. Background Technology

[0002] The detection of combustion cone drop tendency is a crucial step in assessing the quality and safety of cigarette products. Its core lies in simulating the consumer's flicking behavior of the cigarette and accurately identifying the phenomenon of combustion cone detachment. However, existing cigarette combustion cone drop tendency testers have the following shortcomings in the experimental process:

[0003] 1. Ash particles from combustion can easily disperse and accumulate inside the detector, especially contaminating the optical sensor lens, the guide rail of the motion mechanism, and the transmission components. This contamination can not only accelerate mechanical wear but also reduce the sensitivity and reliability of the sensor, affecting the long-term stability of the equipment.

[0004] 2. Residual soot interferes with image recognition accuracy: Soot that is not removed in time adheres to the sample holding area or background plate, which will change the visual characteristics of the detection area and cause the machine vision algorithm to misjudge. For example, when evaluating the maximum deviation of the combustion cone, residual ash may be misidentified as part of the current sample's combustion cone or obscure the true combustion line outline, thereby reducing the accuracy and repeatability of the test results.

[0005] 3. High frequency and low efficiency of cleaning and maintenance: Existing cleaning devices mostly use water tanks or collection boxes (such as ash collection boxes and cigarette butt collection boxes) that require manual water filling. When dealing with a large number of samples, residual ash and cigarette butts accumulate rapidly. Experimenters need to frequently interrupt the test to clean the containers and replace the water (for extinguishing cigarette butts). This not only greatly increases the labor intensity of the operators, but also reduces the overall operating efficiency and automation of the testing equipment, making it difficult to meet the needs of high-throughput quality inspection.

[0006] In existing technologies, various ash collection devices exist. For example, patent CN212279869U discloses a self-cleaning fire-extinguishing ceramic ashtray, specifically relating to the field of ceramic ashtrays. It features a receiving plate and a self-cleaning device. The receiving plate divides the accommodating cavity into a fire-extinguishing chamber and a collection chamber. The collection chamber is used to hold ash and cigarette butts, and a connecting port connects the fire-extinguishing chamber and the collection chamber. After use, the self-cleaning device sweeps the cigarette butts and ash from the collection chamber into the fire-extinguishing chamber through the connecting port, extinguishing the fire and effectively preventing ash from being blown out of the ashtray and soiling the tabletop. This ashtray uses physical partitions to divide functional areas, connects these areas using specific channels, and employs an automated, motor-driven method to replace manual ash handling, considering how users can conveniently clean up accumulated waste. However, this ashtray uses water for fire extinguishing, and the container containing water-soaked ash needs to be cleaned, which may be more cumbersome and make the container dirtier. In addition, it is clearly a ceramic ashtray, suitable for civilian or office settings, but not for the aforementioned cigarette combustion cone drop tendency measuring instrument.

[0007] Therefore, the aforementioned defects collectively restrict the analytical accuracy and continuous working capability of the cigarette combustion cone drop tendency tester, which is a technical bottleneck that urgently needs to be optimized in the current cigarette combustion performance testing. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a soot collection device that is suitable for cigarette combustion cone drop tendency measuring instruments and can achieve directional collection and rapid cleaning of soot, ensuring continuous testing and data accuracy.

[0009] To achieve the above and related objectives, this utility model provides a soot collection device, including a guide funnel, a negative pressure dust collection box detachably connected to the guide funnel, and a fire extinguishing chamber with a variable gap installed between the guide funnel and the negative pressure dust collection box. The negative pressure dust collection box is used to provide active negative pressure to remove soot that is suffocated after being guided into the fire extinguishing chamber by the guide funnel, and to store and remove the suffocated soot from the soot collection device.

[0010] Furthermore, the inner wall surface of the guide funnel is provided with a coating to prevent the adsorption of soot.

[0011] Furthermore, a conductive copper mesh is also installed on the inner wall of the guide funnel.

[0012] Furthermore, the guide funnel also includes an electrostatic elimination module integrated into the conductive copper mesh.

[0013] Furthermore, it also includes a first slide rail and a second slide rail that are longitudinally spaced along the inner wall of the ash collection device, as well as a first fire extinguishing plate that can be slidably installed on the first slide rail and a second fire extinguishing plate that can be slidably installed on the second slide rail; the first fire extinguishing plate and the second fire extinguishing plate form a fire extinguishing chamber with variable gap by moving towards each other.

[0014] Furthermore, both the first and second fire extinguishing boards are fire blankets.

[0015] Furthermore, it also includes a third slide rail installed at the bottom of the guide funnel, through which the negative pressure dust collection box is detachably connected to the guide funnel.

[0016] Furthermore, a vacuum cleaner motor is installed inside the negative pressure dust collection box.

[0017] Furthermore, a collection box is provided inside the negative pressure dust collection box, and a dust collection bag is replaceably fitted inside the collection box.

[0018] Furthermore, a handle is installed on the outer wall of the negative pressure dust collection box.

[0019] The beneficial technical effects of this utility model are as follows:

[0020] This invention utilizes a guide funnel and a negative pressure dust collection box to achieve directional collection and rapid cleaning of smoke ash; the variable gap fire extinguishing chamber ensures fire extinguishing effect and eliminates the need for frequent chamber cleaning, resulting in higher efficiency.

[0021] This invention achieves zero-residue soot fall through an anti-smoke ash adsorption coating; prevents secondary reignition of soot through a fire extinguishing chamber; and avoids frequent shutdowns to clean accumulated soot through replaceable dust collection bags. The dust collection bag can be replaced within 10 seconds in the negative pressure dust collection box without disassembly and washing.

[0027] Unless otherwise defined, all technical and / or scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. It should be understood that certain features of this invention (described in the context of separate embodiments for clarity) may also be provided in combination in a single embodiment. Conversely, multiple features of this invention (described in the context of a single embodiment for brevity) may also be provided separately or in any suitable combination or, where appropriate, in any other described embodiment of this invention. Certain features described in the context of various embodiments will not be considered essential features of those embodiments unless the embodiment is inoperable without those elements. The present invention is further illustrated below by specific examples; however, it should be noted that the specific process conditions and results described in the embodiments of this invention are for illustrative purposes only and should not be construed as limiting the scope of protection of this invention. All equivalent changes or modifications made in accordance with the spirit and essence of this invention should be covered within the scope of protection of this invention.

[0028] like Figure 1 As shown, this utility model provides a soot collection device, including a guide funnel 1, a negative pressure dust collection box 2 detachably connected to the guide funnel 1, and a fire extinguishing chamber with a variable gap installed between the guide funnel 1 and the negative pressure dust collection box 2. The negative pressure dust collection box 2 is used to provide active negative pressure to remove soot that is suffocated after being guided into the fire extinguishing chamber by the guide funnel 1, and to store and remove the suffocated soot from the soot collection device.

[0029] Furthermore, the ash collection device of this application is used in a cigarette combustion cone drop tendency tester. It can be fixed at the bottom of the combustion chamber of the tester. The ash after combustion in the tester enters the ash collection device to be extinguished and collected.

[0030] Furthermore, the guide funnel 1 of this application is used to receive and guide residual smoke and soot to fall vertically, concentrating and transporting them to the fire extinguishing chamber. The inner wall surface of the guide funnel 1 is provided with an anti-smoke ash adsorption coating (not shown in the figure), which can be applied by methods including but not limited to spraying. This anti-smoke ash adsorption coating ensures zero residue soot falls. The anti-smoke ash adsorption coating can be an existing fluoropolymer coating, ceramic-based composite coating, etc. Furthermore, the inner wall of the guide funnel 1 of this application is also provided with a conductive copper mesh (not shown in the figure). The conductive copper mesh provides a discharge path, rapidly conducting static charge to the ground to prevent charge accumulation, and the mesh structure can disperse and weaken the electrostatic field to a certain extent. An electrostatic eliminator module (not shown in the figure) is integrated into the conductive copper mesh. The electrostatic eliminator module is connected to an external grounding terminal to avoid detection errors caused by soot adhesion. The electrostatic eliminator module can be an existing ionization eliminator or similar device.

[0031] Furthermore, this application also includes a first slide rail and a second slide rail installed longitudinally at intervals along the inner wall of the ash collection device, and a first extinguishing plate 3 slidably installed on the first slide rail and a second extinguishing plate 4 slidably installed on the second slide rail; the first extinguishing plate 3 and the second extinguishing plate 4 form a variable-gap extinguishing chamber by moving towards each other. Furthermore, the first and second slide rails serve as installation and guiding references, ensuring that the first extinguishing plate 3 and the second extinguishing plate 4 slide smoothly along the designed trajectory without deviation or jamming. The first extinguishing plate 3 and the second extinguishing plate 4 can move precisely along the slide rails under the drive of a driving device such as a motor, cylinder, or manual mechanism. Through the opposing movement of the two extinguishing plates, the size of the extinguishing chamber formed between them can be flexibly changed, thereby accommodating different amounts of ash and ensuring complete extinguishing of the ash. When the soot falls in, the first extinguishing plate 3 and the second extinguishing plate 4 move towards each other, forming an adjustable closed or semi-closed extinguishing chamber, thereby effectively isolating oxygen, suffocating the fire, ensuring that the soot is completely extinguished, and preventing the soot from reigniting.

[0032] Furthermore, both the first fire extinguishing plate 3 and the second fire extinguishing plate 4 in this application are fire blankets. The fire blankets in this application can be commercially available fire blankets, and their materials include, but are not limited to, glass fiber, ceramic fiber, high silica fiber, etc., which can effectively smother fires.

[0033] Furthermore, this application also includes a third slide rail installed at the bottom of the guide funnel 1, through which the negative pressure dust collection box 2 is detachably connected to the guide funnel 1. The negative pressure dust collection box 2 can be easily pulled out along the third slide rail, facilitating the replacement of the dust collection bag 6 or the removal of potentially clogged soot, thereby improving the ease of maintenance, flexibility of use, and long-term reliability of the soot collection device.

[0034] Furthermore, such as Figure 1As shown, the negative pressure dust collection box 2 of this application is equipped with a vacuum cleaner motor 5 and a collection box, and a replaceable dust collection bag 6 is installed inside the collection box. The vacuum cleaner motor 5 is used to suck up the residual smoke and soot after the cigarette is extinguished into the dust collection bag 6. This application avoids frequent shutdowns to clean the accumulated soot by using a replaceable large-capacity dust collection bag 6. The dust collection bag 6 can be replaced within 10 seconds without disassembly and washing.

[0035] Furthermore, a handle (not shown in the figure) is installed on the outer wall of the negative pressure dust collection box 2 of this application.

[0036] Furthermore, the working principle of the soot collection device of this application is as follows:

[0037] Using the guide funnel 1, the ash collection device is fixed at the bottom of the combustion chamber of the cigarette combustion cone drop tendency tester. The ash after combustion by the tester is collected and guided by the guide funnel 1 and falls into the extinguishing chamber for complete extinguishing. Then, the ash is sucked into the dust collection bag 6 in the negative pressure dust collection box 2 by the vacuum cleaner motor 5. After the dust collection bag 6 is full, the operator can pull the handle to replace the dust collection bag 6.

[0038] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
