[0002] In the tobacco industry, heated cigarettes, as a novel tobacco product, have received widespread attention in recent years. Heated cigarettes release the active ingredients in tobacco through heating rather than combustion, thereby reducing the production of harmful substances. However, the degree of carbonization of the tobacco shreds inside heated cigarettes directly affects their taste, aroma release, and the amount of harmful substances generated; therefore, monitoring the degree of tobacco carbonization is particularly important.

[0003] Chinese utility model patent CN221707310U discloses a device for rapidly monitoring the uniformity of flavoring in cigarettes. The device includes a body with an image sensor and a cigarette cutting device. The cigarette cutting device includes a support assembly for fixing the cigarette to be tested and a cutter for cutting the cigarette. The support assembly includes two vertically arranged support rods with semi-circular frames at their top ends, the openings of which face forward and backward. The cutter cuts the cigarette parallel to its long axis. After cutting, the image sensor takes a picture of the cut cigarette. The device also includes an image processor that analyzes and processes the image captured by the image sensor. However, because there is only one support assembly, the image sensor can only acquire an image of a single cigarette within the support assembly after cutting, resulting in low acquisition efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a cigarette image acquisition device to solve the problem of low acquisition efficiency in existing cigarette image acquisition devices.

[0005] To solve the above-mentioned technical problems, the present invention provides a cigarette image acquisition device with the following technical solution:

[0006] The cigarette image acquisition device includes a housing and a cigarette cutter for cutting cigarettes longitudinally. A camera is installed inside the housing, and multiple cigarette support structures are installed on the bottom wall of the housing to support the cut cigarettes. The camera can acquire images of the cut cigarettes placed in the cigarette support structures.

[0007] Furthermore, the smoke support structure is a slot set on the bottom wall of the box.

[0008] Furthermore, the shape of the slot is adapted to the shape of the cigarette, and the width of the slot is not greater than the width of the cigarette after it has been cut. Furthermore, the slots are arranged in a matrix on the bottom wall of the box.

[0009] Furthermore, the camera is mounted on the top wall of the enclosure in an adjustable vertical direction.

[0010] Furthermore, the top wall of the enclosure is also provided with multiple light source modules, and the positions of the light source modules correspond to at least a portion of the smoke support structure.

[0011] Furthermore, the cigarette cutter includes a base and a blade. The base has a receiving cavity with a semi-circular cross-section adapted to the shape of the cigarette for placing the cigarette, and the opening of the receiving cavity faces upward.

[0024] This invention proposes a novel technical solution to address the problems existing in the aforementioned technical solutions. The core concept of this invention is: a cigarette cutter and a camera are installed inside a housing, and multiple cigarette support structures are installed at the bottom of the housing. These support structures support the cigarettes cut by the cigarette cutter. Multiple support structures can hold multiple cut cigarettes, facilitating simultaneous image analysis of multiple cigarettes heated to different degrees by the camera, and also allowing for image capture of multiple cigarettes heated to the same degree, significantly improving the collection efficiency of the cigarette collection device.

[0025] In view of the above-mentioned inventive concept, the present invention provides a cigarette image acquisition device including as follows: Figure 1 The diagram shows a housing 1 and a cigarette cutter 5 for cutting cigarettes 6 longitudinally. A camera 2 is installed inside the housing 1. In this embodiment, the camera 2 is connected to a control box 7, and its activation is controlled by the control box 7. In other embodiments, the camera can also be manually activated. Multiple cigarette support structures are provided on the bottom wall of the housing 1 to support the cigarettes. The camera 2 can capture images of the cut cigarettes 6 placed within these support structures. Figure 7 As shown, multiple cigarette support structures can hold multiple cut cigarettes 6. Thus, the camera 2 installed inside the box can simultaneously capture images of multiple cigarettes 6 heated to different degrees, or capture images of multiple cigarettes 6 heated to the same degree, which greatly improves the acquisition efficiency of the cigarette acquisition device.

[0026] In use, the cigarette cutter 5 inside the housing 1 is used to cut the cigarettes 6 that have undergone different heating times. Then, the cut cigarettes 6 are placed on the cigarette support structure according to their heating time (or different cigarettes 6 heated to the same time are cut and placed on different cigarette support structures). Subsequently, the control box 7 activates the camera 2 to take pictures of the cigarettes 6 to complete the image acquisition of the degree of carbonization of the tobacco in the cigarettes 6. Subsequent analysis can then be performed to achieve accurate monitoring of the degree of carbonization of the tobacco in the cigarettes 6, providing strong support for the optimization of the production process and quality control of heated cigarettes.

[0027] In this embodiment, the box 1 is semi-open (without a front wall and a right wall), which facilitates manual use of the cigarette cutter 5 and also makes it easy to place the cut cigarettes 6 into the cigarette support structure. It is conceivable that in another embodiment, the side walls of the box can also be designed to be fully enclosed. In this case, to facilitate the cutting and placement of cigarettes, a cabinet door can be provided on the box.

[0028] In this embodiment, the smoke support structure is as follows: Figure 1 The slot 4 shown is located on the bottom wall of the housing. The slot 4 has a simple structure and can effectively support the cigarette 6. In other embodiments, the cigarette support structure can also be a corrugated plate placed on the bottom of the housing, and the groove wall of the corrugated plate can be used to place the cigarette.

[0029] In this embodiment, the shape of the slot 4 is adapted to the shape of the cigarette, and the width of the slot 4 is not greater than the width of the cut cigarette 6. This ensures that the cigarette 6 will not slip or tilt when placed on the slot 4, guaranteeing that the cut cigarette 6 can be stably distributed on the bottom wall of the box. The fact that the width of the slot 4 is not greater than the width of the cut cigarette 6 ensures that the cigarette 6 will not be lower than the top of the slot 4 after being placed there. In this case, the slot wall of the slot 4 will not project onto the cigarette, ensuring the accuracy of image acquisition. Of course, in other embodiments, the slot can also be a rectangular slot, and the width of the rectangular slot must not be greater than the width of the cut cigarette, so that the cut cigarette can be stably placed on the rectangular slot.

[0030] In this embodiment, the slots 4 are arranged in a matrix on the bottom wall of the box. There are nine slots 4 in this embodiment; however, in other embodiments, the number of slots can be different. The evenly distributed slots 4 facilitate analysis by staff and also make more efficient use of the space on the bottom wall of the box. Furthermore, in other embodiments, the slots can be placed at different positions on the bottom wall of the box as needed.

[0031] In this embodiment, as Figure 2 , Figure 4As shown, the camera 2 is adjustable in the vertical direction and mounted on the top wall of the housing 1. The camera 2, located on the top wall of the housing 1, has a wide field of view, facilitating image acquisition of cigarettes 6 placed on the bottom wall of the housing. Alternatively, in other embodiments, the camera can also be placed on the side wall of the housing, as long as it can capture images of cigarettes placed on the bottom wall of the housing. In this embodiment, the camera 2 is mounted on the top wall of the housing 1 via a telescopic rod 21. The camera 2 is mounted on the movable end of the telescopic rod 21, and the other end of the telescopic rod 21 is provided with... Figure 2 The fixing plate 22 shown is connected to the top wall of the housing by fixing screws 23. When it is necessary to capture images of cigarettes 6 of different sizes or when cigarettes 6 are placed in different slots 4, the camera 2 can adjust its height via the telescopic rod 21 to capture images of the cigarettes 4. In addition, in other embodiments, the camera can also be fixedly installed on the top wall of the housing, as long as it can capture images of the cut cigarettes located on the bottom wall of the housing.

[0032] In this embodiment, as Figure 2 , Figure 3 As shown, multiple light source modules 3 are also installed on the top wall of the housing, and the positions of the light source modules 3 correspond to at least a portion of the smoke support structure. The light source modules 3 are connected to the control box 7 via wires. When pattern acquisition is required, the control box 7 controls the activation of the camera 2 and the light source modules 3 via a switch. The light source modules 3 are composed of... Figure 2 The system consists of 32 LEDs, the brightness of which can be adjusted according to different environments to provide suitable brightness for the image acquisition environment when the camera is working. The light source module 3 formed by the LEDs 32 is rectangular, and the light source module 3 corresponds to at least part of the cigarette support structure, thus ensuring that the brightness of each cigarette surface is the same during image acquisition, improving the accuracy of image acquisition. Furthermore, in another embodiment, the light source module can also be set at different positions on the top wall of the housing as needed.

[0033] In this embodiment, the cigarette cutter 5 includes, as follows: Figure 5The base 52 and blade 54 are shown. The base 52 has a semi-circular cross-section that matches the shape of the cigarette for holding the cigarette. The opening of the cavity faces upward. When the cigarette 6 is placed in the upward-facing cavity, it will be stably positioned in the cavity due to its own weight. In this case, no additional clamping device is needed on the base 52. Of course, in other embodiments, the opening of the cavity of the base may also face to the side. In this case, a clamping device is required on the base, and the blade cuts the cigarette vertically. In this embodiment, there are three cigarette cutters 5. Of course, in other embodiments, the number of cigarette cutters may also be different. In this embodiment, to avoid losing the cigarette cutters, the cigarette cutters are placed inside the housing. Of course, the cigarette cutters may be placed outside the housing for convenient cigarette cutting.

[0034] In this embodiment, the base 52 has a U-shaped groove structure that runs through the entire length of the device, and one end is equipped with a detachable baffle 53. The inner wall of the U-shaped groove and the baffle 53 together form the receiving cavity. Thus, when the cigarette cutter 5 is used to cut the cigarette 6, as... Figure 5 , Figure 6 As shown, the baffle 53 can be used to prevent the cigarette 6 from sliding within the receiving cavity, ensuring that the cigarette cutting process can be carried out reliably. After cutting is completed, the baffle 53 can be removed to facilitate the pushing of the cut cigarette 6 along the cavity wall. Of course, in another embodiment, the front and rear of the base may not be continuous; in this case, the receiving cavity is formed by a semi-circular groove provided on the base.

[0035] After the cigarette cutter 5 has cut the cigarette 6, the base 52 can be moved to the vicinity of the corresponding slot 4, and the baffle 53 can be removed to facilitate pushing the cigarette 6 along the wall of the receiving cavity and pushing the cigarette 6 into the slot 4. In this embodiment, the cigarette cutter 5 is separate from the housing 1. Of course, in other embodiments, the cigarette cutter 5 can also be fixedly installed on the bottom wall of the housing. In this case, the cigarette needs to be pinched out and placed into the slot.

[0036] In this embodiment, one end of the inner wall of the U-shaped groove has an upward-facing slot, and the baffle 53 is inserted into the slot. The slot structure is simple, and it also makes the baffle 53 easy to install and remove. In addition, in other embodiments, the baffle can also be connected to the base by bolts. In another embodiment, a slot can be provided on one side of the base, and a buckle can be provided on the baffle. The buckle can cooperate with the slot to achieve a detachable connection between the two.

[0037] In this embodiment, gripping members 51 are respectively provided on the two outer sides of the base 52. Each gripping member 51 has a vertical side that is fixed to the side of the base 52 and a bottom surface flush with the bottom surface of the base 52. A concave arc-shaped gripping surface exists between the vertical side and the bottom surface. The arc-shaped gripping surface of the gripping member 51 facilitates manual gripping, and the gripping member 51 facilitates the movement of the base 52. Furthermore, in other embodiments, gripping surfaces that facilitate gripping can also be provided on both sides of the base. In this case, the gripping surface of the base can be directly gripped to move the base.
