The fixing sleeve is used to be sleeved on the light-emitting device and is threaded with the light-emitting device from the side of the adjusting device away from the tobacco segment to limit the adjusting device.
[0016] In some embodiments, the light-emitting device comprises a main body and a light-emitting assembly. The main body is configured as a hollow cylindrical structure. The axial direction of the main body is consistent with the length direction. The adjusting device is sleeved on the main body and is configured to be movable along the surface of the main body. The hollow region of the main body is used to arrange the light-emitting assembly.
[0017] In some embodiments, the light-emitting assembly comprises a cover cylinder, a battery and a light-emitting piece. Part of the cover cylinder is inserted into the hollow region of the main body. The hollow region of the cover cylinder and the hollow region of the main body jointly define a cavity. The battery and the light-emitting piece are both arranged in the cavity. The filter segment abuts against the outer side of the top wall of the cover cylinder. The battery is used to provide electric energy for the light-emitting piece. At least part of the top wall of the cover cylinder is transparently arranged to make the light emitted by the light-emitting piece pass through the top wall to irradiate the filter segment.
[0018] Based on the technical scheme provided in the application, the water-based paper hole observation device comprises a cigarette holder, a light-emitting device and an adjusting device. The cigarette holder comprises a mounting seat and a plurality of clamping heads arranged at intervals in the circumferential direction of the mounting seat. The gap on the radially inner side of the plurality of clamping heads is used to place the filter segment of the cigarette. The filter segment comprises water-based paper wrapped on the surface of the filter segment. The light-emitting device is used to emit light to irradiate the filter segment from the end of the filter segment away from the tobacco segment in the length direction of the cigarette.

[0030] Reference Figures 1 to 4Some embodiments of the present application provide a tipping paper hole observation device, comprising a cigarette holder 1, a light emitting device 2 and an adjusting device 3. The cigarette holder 1 comprises a mounting seat 13 and a plurality of clamping heads 11 arranged at intervals in the circumferential direction of the mounting seat 13. The gap on the radial inner side of the plurality of clamping heads 11 is used to place the filter segment A1 of the cigarette A. The filter segment A1 comprises tipping paper wrapped on the surface of the filter segment A1. The light emitting device 2 is used to emit light to irradiate the filter segment A1 from the end of the filter segment A1 away from the tobacco segment A2 along the length direction X of the cigarette A. The adjusting device 3 is configured as a hollow cylindrical structure and is located radially outside the cigarette holder 1. The adjusting device 3 is movable relative to the cigarette holder 1 along the length direction X to press the plurality of clamping heads 11 to move the plurality of clamping heads 11 in the radial direction to adjust the size of the gap.
[0031] Specifically, Figure 1 The use state of the tipping paper hole observation device is shown, the length direction X of the cigarette A coincides with the height direction, the light emitting device 2 and the tobacco segment A2 are respectively located on both sides of the filter segment A1 in the length direction X, or in other words, the light emitting device 2 is located on the lower side of the filter segment A1, and the tobacco segment A2 is located on the upper side of the filter segment A1. The middle part of the mounting seat 13 is provided with a through hole, and the light emitted by the light emitting device 2 passes through the through hole in the middle part of the mounting seat 13 to irradiate the filter segment A1.
[0032] By clamping the cigarette from different positions in the circumferential direction by the plurality of clamping heads 11, the cigarette A is subjected to uniform force, which ensures the stability of the cigarette and facilitates observation of the holes on the tipping paper from all directions in the clamped state. And by adjusting the radial gap of the plurality of clamping heads 11 through the adjusting device 3, the tipping paper hole observation device can be adapted to cigarettes of various sizes, increasing the scope of application, so that cigarettes of different sizes can use the tipping paper hole observation device provided by the present application, without the need to design multiple clamping tools specifically, thereby improving the convenience of observation and detection efficiency, and reducing the cost of observation.
[0033] It is worth noting that the distribution of the plurality of clamping heads 11 in the circumferential direction is located on the same circumference, so that when the adjusting device 3 moves up and down, the movement of the plurality of clamping heads 11 in the radial direction is synchronous, which can ensure that the displacement of the plurality of clamping heads 11 in different directions is always equal, thereby improving the clamping effect on the cigarette A.
[0034] In some embodiments, the number of clamping heads 11 is configured to be three, and the three clamping heads 11 are evenly spaced in the circumferential direction, and the interval between two adjacent clamping heads 11 is 60°. This can improve the stability of clamping the cigarette A.
[0035] In some embodiments, the first end of the clamping head 11 away from the tobacco segment A2 is rotationally connected to the second end of the mounting seat 13 for clamping the filter segment A1.
[0036] Specifically, the mounting seat 13 is arranged on the upper end face of the light emitting device 2, and the second end of the clamp head 11 is connected to the mounting seat 13 in a rotary connection manner, so that when the adjusting device 3 presses the clamp head 11, the clamp head 11 is deflected towards the center of the gap with the first end as the rotation center, thereby overlapping with the filter segment A1 to achieve clamping of the filter segment A1.
[0037] In order to advantageously achieve the deflection of the clamp head 11 during the movement of the adjusting device 3, with reference to Figure 5 In some embodiments, the radially outer side of the clamp head 11 gradually expands from the second end of the clamp head 11 to the first end of the clamp head 11. In this way, when the adjusting device 3 is moved downward, the inner wall of the adjusting device 3 will press against the gradually expanding outer side of the clamp head 11, generating a force that drives the clamp head 1 to deflect towards the cigarette A, thereby better achieving the deflection of the clamp head 11.
[0038] Still referring to Figure 5 In some embodiments, the cigarette clamp 1 includes a protrusion 12 arranged at the second end of the clamp head 11. The protrusion 12 protrudes in the direction close to the gap relative to the clamp head 11, and the protrusion 12 is used to abut and clamp the filter segment A1.
[0039] Compared with the scheme without the protrusion 12, this scheme can make the protrusion 12 abut against the cigarette A with a smaller angle of rotation of the clamp head 11, and the arrangement of the protrusion 12 can also increase the stability of clamping the cigarette A.
[0040] In some embodiments, the end face of the protrusion 12 for abutting and clamping the filter segment A1 is configured as a smooth curved surface, which can reduce damage to the surface of the cigarette A when clamping the cigarette A.
[0041] In some embodiments, the cigarette clamp 1 includes two vertical plates arranged at the first end of the clamp head 11. The two vertical plates are arranged in parallel and spaced apart in the thickness direction of the clamp head 11. The two vertical plates are provided with coaxial through holes. The mounting seat 13 includes a plurality of mounting portions arranged spaced apart in the circumferential direction of the mounting seat 13. The plurality of mounting sites are respectively used to mount a plurality of clamp heads 11. Each mounting portion includes two parallel and spaced apart mounting plates. The two mounting plates protrude radially outward relative to the mounting seat 13, and the two mounting plates are provided with coaxial mounting holes. The two vertical plates of the first end of the clamp head 11 are inserted between the two mounting plates of the mounting portion, the through holes of the vertical plates and the mounting holes of the mounting plates are coaxial, and the rotation connection of the clamp head 11 is achieved by passing a pin shaft through the through holes of the vertical plates and the mounting holes of the mounting plates.
[0042] With reference to Figure 5In some embodiments, the tipping paper hole observation device further comprises a plurality of elastic members 5. The plurality of elastic members 5 are respectively arranged at the first ends of the plurality of clamping heads 11. The elastic members 5 are located between the radial outer side of the mounting seat 13 and the clamping heads 11. When the adjusting device 3 moves away from the filter segment A1, the degree of extrusion of the inner wall of the adjusting device 3 and the plurality of clamping heads 11 gradually increases, so that the plurality of clamping heads 11 overcome the elastic force of the plurality of elastic members 5 to radially contract to reduce the gap. When the adjusting device 3 moves towards the filter segment A1, the degree of extrusion of the inner wall of the adjusting device 3 and the plurality of clamping heads 11 gradually decreases, so that the plurality of clamping heads 11 radially expand under the elastic force of the plurality of elastic members 5 to increase the gap.
[0043] Specifically, when it is necessary to reduce the size of the gap to adapt to a smaller size of the cigarette, by moving the adjusting device 3 downward, the plurality of clamping heads 13 are deflected towards the positive center of the gap, and the positions of the clamping heads 11 close to the first ends also deflect to a certain extent to extrude the elastic members 5. After the elastic members 5 are extruded, the elastic members 5 exert a force on the clamping heads 11 to drive the clamping heads 11 to return to the original position, but under the extrusion of the adjusting device 3, the clamping heads 11 can remain stationary to achieve clamping of the cigarette A. When the adjusting device 3 is moved upward, the extrusion of the adjusting device 3 on the clamping heads 11 decreases, and the force of the elastic members 5 can drive the clamping heads 11 to return to the original position, or in other words, drive the clamping heads 1 to deflect towards the direction away from the positive center of the gap, until the clamping heads 11 abut against the inner wall of the adjusting device 3. At this time, the radial gap of the second ends of the plurality of clamping heads 11 is enlarged to adapt to a larger size of the cigarette A.
[0044] Therefore, by arranging the elastic members 5, the adjustment of the radial gap of the plurality of clamping heads 11 is facilitated.
[0045] In some embodiments, the elastic members 5 comprise torsional springs. The torsional springs have two torsional arms, one of which is arranged on the mounting seat 13, and the other of which is arranged on the clamping head 11.
[0046] The torsional spring comprises a helical spring body and two torsional arms arranged at both ends of the spring body. The spring body is arranged around a pin shaft penetrating the through hole of the vertical plate and the mounting hole of the mounting plate. When the clamping head 1 deflects towards the positive center of the gap, the two torsional arms are close to each other, and the spring body is extruded. When the adjusting device 3 is moved upward, the elastic force of the spring body drives the two torsional arms to move away from each other, thereby pushing the clamping head 11 away from the mounting seat 13, or in other words, away from the positive center of the gap.
[0047] The use of torsional springs can achieve the adjustment of the radial gap of the plurality of clamping heads 11 at a lower cost.
[0048] In some embodiments, the surface of the light emitting device 2 is provided with external threads. The inner wall of the adjusting device 3 is provided with internal threads. The adjusting device 3 is sleeved on the light emitting device 2 and moves along the surface of the light emitting device 2 through threaded cooperation.
[0049] Specifically, through threaded cooperation, the adjusting device 3 can be moved up and down along the light emitting device 2 by screwing the adjusting device 3, which increases the convenience of adjusting the size of the gap.
[0050] Reference Figures 1 to 3 , 5, In some embodiments, the tipping paper hole observation device further comprises a fixing sleeve 6. The fixing sleeve 6 is configured as a hollow cylindrical structure. The inner wall of the fixing sleeve 6 is provided with internal threads. The fixing sleeve 6 is used to be sleeved on the light emitting device 2 and is threaded with the light emitting device 2 from the side of the adjusting device 3 away from the tobacco segment A2 to limit the adjusting device 3.
[0051] After adjusting the radial gap of the plurality of collets 11 to the desired size by screwing the adjusting device 3, the fixing sleeve 6 is screwed from the lower side of the adjusting device 3 to limit the adjusting device 3 from the lower side, which increases the positional stability of the adjusting device 3 and is conducive to the position of the adjusting device 3 not changing when observing the holes on the tipping paper in different directions after the plurality of collets 11 clamps the cigarette A, thereby enabling the plurality of collets 11 to more stably clamp the cigarette A.
[0052] Reference Figure 5 and 6 In some embodiments, the light emitting device 2 comprises a main body 21 and a light emitting assembly. The main body 21 is configured as a hollow cylindrical structure. The axial direction of the main body 21 is consistent with the length direction. The adjusting device 3 is sleeved on the main body 21 and is configured to be movable along the surface of the main body 21. The hollow area of the main body 21 is used to arrange the light emitting assembly.
[0053] Specifically, the main body 21 and the adjusting device 3 are both configured as cylinders and coaxially arranged, which can enable the main body 21 to guide the adjusting device 3 to stably move along the surface of the main body 21. The light emitting assembly is arranged in the hollow area of the main body 21, which can realize the compact design of the tipping paper hole observation device, making the overall volume of the tipping paper hole observation device smaller, and also can protect the light emitting assembly.
[0054] In some embodiments, the light emitting assembly comprises a cover cylinder 22, a battery 23 and a light emitting piece 24, part of the cover cylinder 22 is inserted into the hollow area of the main body 21, the hollow area of the cover cylinder 22 and the hollow area of the main body 21 together define a cavity, the battery 23 and the light emitting piece 24 are both arranged in the cavity, the filter segment A1 abuts the outer side of the top wall of the cover cylinder 22, the battery 23 is used to provide electric energy for the light emitting piece 24, and at least part of the top wall of the cover cylinder 22 is transparent to enable the light emitted by the light emitting piece 24 to pass through the top wall and irradiate the filter segment A1.
[0055] Specifically, the surface of the cover cylinder 22 is provided with external threads, the inner wall of the hollow region of the main body 21 is provided with internal threads, the cover cylinder 22 is threadedly engaged with the main body 21, thereby achieving stable connection. Further, the part of the cover cylinder 22 exposed outside the hollow region of the main body 21 is provided with external threads, the hole wall of the through hole in the middle part of the mounting seat 13 is provided with internal threads, the mounting seat 13 is threadedly engaged with the cover cylinder 22, and at the same time, the mounting seat 13 is also fixed on the end face of the main body 21 by screws. At this point, the cover cylinder 22, the main body 21, the mounting seat 13, and the plurality of collets 11 are stably connected as a whole, thereby improving the overall structural stability. The overall shape of the battery 23 is cylindrical, thereby being better placed in the hollow region of the main body 21.
[0056] In summary, the cover cylinder 22 can be engaged with the main body 21 to further enclose the light-emitting assembly in the cavity, thereby improving the safety of the light-emitting assembly. Moreover, the top end of the cover cylinder 22 can be used to abut the end face of the filter segment A1 in the length direction X, and cooperate with the plurality of collets 11, thereby improving the stability of the cigarette A.
[0057] In some embodiments, the battery 23 is configured as a conventional No. 5 battery, thereby reducing the cost.
[0058] In some embodiments, the hollow region of the main body 21 extends through the main body 21 in the axial direction, and the water plug hole observation device further comprises a lower end cover 4 for covering the lower end of the main body 21. The light-emitting assembly further comprises a circuit 25 located in the cavity defined by the cover cylinder 22 and the main body 21. The light-emitting member 24 comprises an LED lamp. The electrodes of the LED lamp are respectively connected with the battery 23 and the circuit 25. Moreover, the lower end cover 4 is pressingly arranged to control the on-off of the circuit 25, thereby facilitating the staff to control the light-emitting state of the LED lamp.
[0059] In some embodiments, the light-emitting assembly comprises a lens 26 and a transparent glass 27. The lens 26 is arranged on the upper side of the LED lamp. The lens 26 is used to focus the light emitted by the LED lamp, thereby enhancing the irradiation. The transparent glass 27 is arranged at the top end of the cover cylinder 22 to form the top wall of the cover cylinder 22, and the light emitted by the LED lamp sequentially passes through the lens 26 and the transparent glass 27 to irradiate the filter segment A1. The following briefly describes the use process of the water plug hole observation device of the present application.
[0060] First, manually clamp the three clamps 11 to make them radially retract to create space for the adjustment device 3 to be fitted on the main body 21. When it is necessary to observe the tipping paper of the small-sized cigarette A, by screwing the adjustment device 3 downward, the inner wall of the adjustment device 3 extrudes the three clamps 11, the three clamps 11 deflect towards the gap, thereby adjusting the radial gap of the three protrusions 12 at the second end of the three clamps 11 to the desired size, then screwing the fixing sleeve 4 from the lower side of the adjustment device 3 to lock the adjustment device 3, realizing the position fixation of the three clamps 21. Then insert the cigarette A into the three clamps 21, and press the lower end cover 4, which can control the LED light to emit light and observe.
[0061] When it is necessary to observe the tipping paper of the larger-sized cigarette A, by screwing the adjustment device 3 upward, the extrusion degree of the adjustment device 3 on the three clamps 11 decreases, the elastic force of the torsion spring makes the clamps 11 deflect outward, thereby increasing the radial gap of the three protrusions 12 at the second end of the three clamps 11. Then screw the fixing sleeve 6 upward to make it abut against the adjustment device 3, and complete the fixation.
[0062] Since the cigarette A, the mounting seat 13, the main body 21, the cover cylinder 22, the adjustment device 3 and the fixing sleeve 6 are coaxial, it is convenient to rotate the tipping paper hole observation device during the observation process to observe the hole from different directions, which can better observe the hole on the tipping paper.
[0063] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application and not to limit them; although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the specific embodiments of the present application can be modified or some technical features can be replaced by equivalent ones; without departing from the spirit of the technical solutions of the present application, they should be covered in the technical solution range of the present application.
