[0030] like Figure 1 and Figure 2 As shown, Figure 1 and Figure 2 The three-dimensional structure diagram and side view of a cigarette smoldering detection device provided in one embodiment of the utility model are shown respectively. In this embodiment, the cigarette smoldering detection device includes:

[0031] Base 1;

[0032] The smoldering rack 2 is vertically fixed on the base 1. The smoldering rack 2 is provided with a plurality of cigarette fixing mechanisms 3. The cigarette fixing mechanisms 3 are used to clamp and fix cigarettes so that the axis of the cigarette forms a preset angle with the horizontal plane.

[0033] The electric ignition mechanism 4 is arranged in front of the smoldering frame 2 and can be Figure 1 The device moves back and forth on the smoldering rack 2 as shown in the x direction, and is used to ignite the cigarettes on the smoldering rack 2;

[0034] The photoelectric detection mechanism 5 is arranged between the smoldering frame 2 and the ignition mechanism and is located on one side of the smoldering frame 2. The photoelectric detection mechanism 5 can be arranged in the vertical direction (such as Figure 1 The y direction is shown in the figure to reciprocate to detect whether the smoldering length of the cigarette meets the requirements.

[0035] By adopting this technical solution, the smoldering rack 2 is vertically fixed on the base 1, and the smoldering rack 2 is provided with a cigarette fixing mechanism 3 for fixing the cigarette at a preset angle so that the axis of the cigarette meets the detection requirements of the smoldering length of the cigarette; an electric ignition mechanism 4 that can reciprocate in the horizontal direction is arranged in front of the smoldering rack 2, so that the cigarette can be moved in the direction of the smoldering rack 2 to ignite multiple cigarettes synchronously, thereby improving the ignition efficiency and avoiding burns to the staff during the process of inserting the cigarette after manual ignition; in addition, the photoelectric detection mechanism 5 is used to detect whether the cigarette meets the smoldering length requirement, thereby avoiding errors caused by manual detection and improving the accuracy of detection.

[0036] Specifically, in this embodiment, the preset angle is that when the cigarette is inserted into the cigarette fixing mechanism, the angle between the axis of the cigarette and the horizontal plane does not exceed 15° upwards and the downward deviation should not exceed 0° to meet the angle requirements for cigarette smoldering detection.

[0037] Furthermore, the photoelectric detection mechanism 5 includes a photoelectric emitter 51 and a first fixing frame 52 . The first fixing frame 52 is provided with a first slide groove 53 extending in the vertical direction. The photoelectric emitter 51 is adjustably connected to the first slide groove 53 via a first fastener 54 .

[0038] Specifically, in this embodiment, a plurality of cigarette fixing mechanisms 3 are evenly arranged in a matrix on the smoldering rack 2. That is, the smoldering rack 2 is provided with a plurality of rows and columns of cigarette fixing mechanisms 3.

[0039] The first fixing frame 52 is vertically arranged on one side of the smoldering frame 2, and a first slide groove 53 extending in the vertical direction is arranged on the first fixing frame 52; the emission end of the photoelectric emitter 51 faces the cigarette inserted on the cigarette fixing mechanism 3, and is adjustably connected to the first slide groove 53 through the first fastener 54, so as to be fixed at different heights of the first fixing frame 52. By adjusting the position of the photoelectric emitter 51 in the vertical direction, it is possible to adjust which row of cigarettes the photoelectric emitter 51 irradiates. During detection, the emission end of the photoelectric emitter 51 emits light toward a row of cigarettes, and by checking whether the light emitted by the emission end of the photoelectric emitter 51 irradiates on the cigarette paper of the cigarette, it is determined whether the smoldering length meets the requirements. This technical solution replaces manual measurement with a steel ruler, and multiple cigarettes can be detected at one time, thereby improving the efficiency and accuracy of detection.

[0040] Furthermore, the base 1 is groove-shaped, and second slide grooves 11 are respectively provided on the two side walls of the base 1 located on both sides of the smoldering frame 2. The second slide grooves 11 extend in the horizontal direction; the first fixing frame 52 is adjustably connected to the second slide groove 11 on one side through a second fastener 55.

[0041] Optionally, the first fastener 54 and the second fastener 55 are both locking nuts.

[0042] Specifically, the smoldering rack 2 is vertically fixed in the base 1 and is located on one side of the base 1. Second slide grooves 11 are respectively provided on the side walls on both sides of the base 1. The second slide grooves 11 are arranged to extend along the length direction of the side walls. The first fixed frame 52 is arranged on one side of the base 1 and is slidably connected to the second slide groove 11. A threaded hole is provided at the bottom of the first fixed frame 52. The second fastener 55 is inserted through the second slide groove 11 and connected to the threaded hole of the first fixed frame 52, thereby fixing the first fixed frame 52 at a predetermined position of the second slide groove 11. With this technical solution, the position of the photoelectric detection mechanism 5 can be adjusted in the direction close to the smoldering rack 2 and away from the smoldering rack 2 to meet the detection requirements of cigarettes of different lengths.

[0043] Furthermore, the photoelectric transmitter 51 is a laser transmitter. This technical solution has the characteristics of strong directionality and high brightness.

[0044] Furthermore, the distance between the light source surface emitted by the photoelectric emitter 51 and the end surface of the unlit cigarette is 40 mm.

[0045] In this embodiment, before lighting the cigarette, the light source surface of the laser emitter is set to be 40 mm away from the outer end surface of the cigarette. Optionally, in a specific implementation, the light source emitting surface can be slightly higher than the axis of the cigarette in the vertical direction so as to cover the entire row of cigarettes. Specifically, after the smoldering ends, if there is a light source on the cigarette paper, it is determined that the smoldering length of the cigarette does not meet the requirements, otherwise it meets the requirements. In addition, a ruler can be set on the outside of the second slide groove 11, and the position of the photoelectric emitter 51 can be accurately determined by the ruler, so that it is more convenient to operate when accurately determining the light source surface of the photoelectric emitter 51 according to the length of the cigarette.

[0046] Further, the electric ignition mechanism 4 comprises:

[0047] Two second fixing frames 41, the two second fixing frames 41 are arranged in front of the smoldering frame 2 and are respectively located on both sides of the base 1, a slider 44 is provided on the outer side of the second fixing frame 41, the slider 44 is slidably connected with the second slide groove 11, and a plurality of third slide grooves 43 are arranged at intervals in the vertical direction on the surface of the two second fixing frames 41 facing each other, and a stopper is provided at the end of the third slide groove 43 close to the smoldering frame 2;

[0048] The electric heating block 42 includes an electric heating surface facing the cigarette fixing mechanism 3 . Pulleys are provided below the two ends of the electric heating block 42 , and the pulleys are slidably connected to the third sliding groove 43 .

[0049] Specifically, two second fixing frames 41 are vertically arranged on both sides of the base 1 and are located in front of the smoldering frame 2. Optionally, the distance between the two second fixing frames 41 is the length of the smoldering frame 2 in the horizontal direction. The first fixing frame 52 is located between the second fixing frame 41 and the smoldering frame 2. Optionally, the second fixing frame 41 and the first fixing frame 52 are staggered in the horizontal direction, so that the second fixing frame 41 can avoid the photoelectric transmitter 51 when moving. The outer side of the bottom of the second fixing frame 41 is provided with a slider 44 extending along its width direction. The slider 44 is slidably connected with the second slide groove 11 on the base 1, so that the second fixing frame 41 can be moved toward the smoldering frame 2 and away from the smoldering frame 2. A plurality of third slide grooves 43 arranged in parallel are provided on the inner sides of the two second fixing frames 41 facing each other. The third slide grooves 43 are arranged in the vertical direction and extend in the horizontal direction. The electric heating block 42 is fixed in the third slide groove 43. By installing the electric heating block 42 in the third slide grooves 43 at different heights, cigarettes of different heights can be ignited.

[0050] In this embodiment, the side of the electric heating block 42 facing the cigarette fixing mechanism 3 is set as an electric heating surface, which can increase the contact area between the cigarette and the electric heating block 42. By placing the electric heating surface close to the end of the cigarette, the whole row of cigarettes can be ignited at the same time, which not only allows the cigarettes to fully contact with the electric heating surface for combustion, but also allows the cigarettes to be ignited evenly, thereby improving the ignition efficiency and the convenience of operation, and also preventing the staff from being burned.

[0051] For example, in one embodiment of the present invention, the electric heating wire is embedded in the electric heating block 42, and the end of the electric heating wire corresponds to the position of the corresponding cigarette fixing mechanism 3, thereby forming an electric heating surface. In another embodiment of the present invention, the entire surface can also be made into an electric heating surface.

[0052] A groove is provided below the third slide groove 43, and pulleys are provided at the lower ends of the two ends of the electric heating block 42. By installing the pulleys in the grooves, the two ends of the electric heating block 42 can be respectively installed in the third slide groove 43 of the second fixing frame 41 on both sides. Optionally, in order to smoothly install and stably fix in the third slide groove 43, pulleys are provided at the four corners below the electric heating block 42.

[0053] A stopper is also provided at the end of the third chute 43 near the smoldering rack 2 to prevent the electric heating block 42 from sliding out of the third chute 43. Optionally, in this embodiment, the stopper is a baffle provided at the end of the third chute 43. In other embodiments, the stopper may also be other structures, which are not limited by the present invention, as long as they can block the electric heating block 42.

[0054] Optionally, a layer of sponge is provided at the end of the groove close to the smoldering rack 2, so that when the pulley slides onto the sponge, it can play a buffering role, so that the electric heating block 42 can contact the end of the cigarette smoothly.

[0055] Furthermore, each third sliding groove 43 matches the position of the cigarette fixing mechanism 3 in the corresponding row.

[0056] Specifically, in this embodiment, at the height corresponding to each row of cigarette fixing mechanisms 3, the two second fixing frames 41 are provided with third slide grooves 43. Therefore, the height and number of the third slide grooves 43 match the rows of cigarette fixing mechanisms 3. In this way, multiple cigarettes can be lit simultaneously in rows, thereby improving the lighting efficiency.

[0057] Furthermore, the cigarette fixing mechanism 3 comprises a fixing tube, and a through hole is provided at the bottom of the fixing tube.

[0058] Specifically, the fixed tube is arranged in a basically horizontal direction, with the tube mouth of the fixed tube facing the direction of the electric ignition mechanism 4, and the angle between its axis and the horizontal plane should not exceed 15° upward, and should not exceed 0° downward, so that the fixed tube can fix the cigarette at a preset angle, so that the angle between the axis of the cigarette and the horizontal plane meets the requirements of the smoldering length detection of the cigarette, avoiding the time-consuming adjustment of the cigarette angle and improving the detection efficiency.

[0059] A through hole is provided at the bottom of the fixed cylinder, so that the filter part of the cigarette can be connected to the outside atmosphere, so that the cigarette can be fully burned. Correspondingly, the smoldering rack 2 is provided with air holes at the position where the fixed cylinder is provided, so that the through hole of the fixed cylinder is connected to the outside atmosphere through the air hole of the smoldering rack 2. In order to facilitate the maintenance of the fixed cylinder, in this embodiment, a connecting pipe is provided between the through hole at the bottom of the fixed cylinder and the air hole of the smoldering rack 2, and the two ends of the connecting pipe are respectively welded to the periphery of the air hole of the smoldering rack 2 and the periphery of the through hole at the bottom of the fixed cylinder, so that the fixed cylinder is fixedly connected to the smoldering rack 2. In other embodiments, the air hole can also be aligned with the through hole, and the bottom of the fixed cylinder can be directly welded to the smoldering rack 2.

[0060] Furthermore, a rubber layer is laid on the inner side wall of the fixing cylinder.

[0061] With this technical solution, rubber layers of different thicknesses are arranged on the inner wall of the fixing tube, so that the inner diameter of the fixing tube can be adjusted according to the diameter of the cigarette, so that the detection of various cigarette sizes can be completed without replacing the device, saving costs. In addition, the rubber layer can increase the friction force and can also firmly fix the cigarette in the fixing tube.

[0062] Furthermore, an ash collecting tray 6 is provided on the base 1 , and the ash collecting tray 6 is drawable and arranged in the base 1 .

[0063] The ash collecting tray 6 is used to collect the ash dropped after the cigarette is smoldering. This technical solution is convenient for cleaning and maintenance, saving time and effort.

[0064] Specifically, an opening is provided on the side of the base 1 away from the smoldering rack 2, and the ash collecting tray 6 is in a groove shape, and a handle is provided on one side thereof. The ash collecting tray 6 is inserted into the base 1 from the opening, so as to collect the ash dropped from the cigarettes on the cigarette fixing mechanism 3. Optionally, the end face of one side of the ash collecting tray 6 close to the smoldering rack 2 abuts against the surface of the smoldering rack 2, and the end faces on both sides of the ash collecting tray 6 abut against the second fixing frame 41, so that the size of the ash collecting tray 6 is larger, so as to collect the ash better, and the end faces on both sides of the ash collecting tray 6 and the end faces on both sides of the base 1 have a clamping effect on the second fixing frame 41, and can support the second fixing frame 41.

[0065] During use, insert the cigarette to be tested into the fixing tube of the cigarette fixing mechanism 3, and adjust the emitting end of the photoelectric transmitter 51 to a position 40 mm away from the end face of the outer end of the cigarette. The electric heating block 42 is placed in a third slide groove 43, and the second fixing frame 41 is pushed along the second slide groove 11 and in the direction of the smoldering frame 2 so that the electric heating surface contacts the end face of the cigarette and ignites the cigarette. All cigarettes are lit according to the above method. After the smoldering of the cigarette ends, turn on the photoelectric transmitter 51, and adjust the position of the photoelectric transmitter 51 in the vertical direction to facilitate the detection of the entire row of cigarettes. If there is a light source on the cigarette paper of the cigarette, the cigarette does not meet the smoldering length requirement, otherwise it is determined that the cigarette meets the smoldering length requirement.

[0066] According to the cigarette smoldering detection device provided by the utility model, the cigarette is ignited by an electric ignition mechanism, and whether the cigarette meets the smoldering length requirement is detected by a photoelectric detection mechanism, thereby improving detection efficiency and accuracy and avoiding burns to staff.
