Description

Technical Field

[0001] The utility model relates to the technical field of cigarette detection, and particularly relates to a mounting seat of a cigarette detection device and a cigarette detection device. Background Art

[0002] In the prior art, various treatments need to be performed on cigarettes and the treatment effects need to be detected. For example, a cigarette online laser drilling device is used to complete the drilling of a part of the filter tip of a filter cigarette to accurately control the ventilation rate of the cigarette filter tip. During production, due to reasons such as the dirt on the lens of the laser light path and the accumulation of dirt on the laser drum and the cigarette dialing wheel, problems such as aperture deviation or fewer holes occur in laser drilling, resulting in the over-standard of the filter ventilation rate data and causing fluctuations in the suction taste. Therefore, it is necessary to detect the drilling effect. In a cigarette detection device, a driving device needs to be installed on a mounting seat, and the mounting seat needs to meet requirements such as being convenient for installing components and easy to adjust components.

[0063] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The description of at least one exemplary embodiment is actually only illustrative and in no way restrictive of the present invention and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0064] Unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and values set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationship. Technologies, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods and devices should be regarded as part of the description. In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0065] In the description of the present invention, it should be understood that the use of terms such as "first" and "second" to limit components is only for the convenience of differentiating the corresponding components. Without further statement, the above terms have no special meaning and thus cannot be construed as limiting the scope of protection of the present invention.

[0066] In the description of the present invention, it should be noted that, unless otherwise clearly defined and limited, the terms "mounted", "connected" and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0067] For ease of description, spatial relative terms, such as "above", "over", "on the upper surface", "upper", etc., may be used herein to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, a device described as "above" or "over" other devices or structures will then be positioned "below" or "under" the other devices or structures. Thus, the exemplary term "above" can include both orientations of "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations of the spatial relative descriptions used herein will be made.

[0068] As shown in the figure, the mounting base 7 of the cigarette rod detection device of this embodiment includes a cuboid-shaped frame body and a mounting cavity provided in the frame body. The frame body includes a bottom plate 70 and a first plate body 71, a second plate body 72, a third plate body 73, and a fourth plate body 74 that are sequentially connected end to end on the bottom plate 70. The first plate body 71 and the third plate body 73 are opposite to each other, the second plate body 72 and the fourth plate body 74 are opposite to each other. A motor main shaft mounting hole 710 and first motor mounting holes 711 and second motor mounting holes 712 located on the upper and lower sides of the motor main shaft mounting hole 710 are provided on the first plate body 71. The first motor mounting holes 711 and the second motor mounting holes 712 are strip-shaped holes parallel to each other. The dimension of the motor main shaft mounting hole 710 in the horizontal direction is greater than the dimension in the vertical direction. In this embodiment, the horizontal, vertical, upper and lower directions, etc. are all referenced when the bottom plate of the frame body is installed on the ground. At this time, the first plate body 71 is located above the bottom plate.

[0069] For the mounting base of the cigarette rod detection device of this embodiment, when the motor in the drive assembly of the cigarette rod detection device is installed in the mounting cavity surrounded by the first plate body, the second plate body, the third plate body, and the fourth plate body, it can effectively protect the motor. At the same time, the settings of the motor main shaft mounting hole and the strip-shaped first motor mounting holes and second motor mounting holes located on the upper and lower sides of the motor main shaft mounting hole can adjust the installation position of the motor along the strip-shaped first motor mounting holes and second motor mounting holes. Thus, in the drive assembly with belt drive, the tension of the belt can be conveniently adjusted.

[0070] In some embodiments, the housing further includes a transparent plate body disposed above the first plate body 71, the second plate body 72, the third plate body 73, and the fourth plate body 74, and the transparent plate body faces the bottom plate 70. The transparent plate body can be a transparent glass plate. The arrangement of the transparent plate body facilitates observing the state of the motor in the installation cavity, and also enables easy observation and adjustment of the installation position during the disassembly and installation of the motor. At the same time, it can also prevent dust from entering the installation cavity during daily operation, etc., improving the service life of the cigarette detection assembly.

[0071] In some embodiments, a weight-reducing hole 731 is provided on the third plate body 73, and the projection of the weight-reducing hole 731 on the first plate body 71 covers the motor main shaft mounting hole 710. The setting of the weight-reducing hole 731 can reduce the weight of the housing, contributing to the lightweight of the housing. At the same time, since the projection of the weight-reducing hole 731 on the first plate body 71 covers the motor main shaft mounting hole 710, during the installation of the motor, one can reach into the weight-reducing hole with a hand to adjust the installation position of the motor. In some embodiments, the dimensions of the weight-reducing hole in the horizontal direction and the vertical direction are respectively larger than the dimensions of the motor mounted on the housing in the horizontal direction and the vertical direction. At this time, the motor can be inserted into the weight-reducing hole, facilitating the disassembly and installation of the motor.

[0072] As shown in the figure, the cigarette detection device of this embodiment includes a transmission cylinder 3, a drive assembly, and any one of the above-mentioned mounting seats 7.

[0073] The transmission cylinder 3 includes a first cylinder body 31, a cylinder cavity 32 provided inside the first cylinder body 31, a first transmission part 33 provided on the first cylinder body 31, and a first connection part 34 provided at one end of the first cylinder body 31. The first cylinder body is connected to the second plate body. In the embodiment shown in the figure, the bearing seat is mounted on the second plate body 72, and the first cylinder body is connected to the second plate body 72 through the bearing seat.

[0074] The drive assembly is drivingly connected to the transmission cylinder 3, and the drive assembly is used to drive the transmission cylinder 3 to rotate. In the embodiment shown in the figure, the drive assembly includes a motor 11, a first transmission wheel 12, a second transmission wheel 14, and a belt connecting the first transmission wheel 12 and the second transmission wheel 14. The motor is mounted on the mounting seat 7. The motor includes a motor main shaft and a motor mounting plate for mounting the motor. The motor mounting plate is located at the end of the motor close to the motor main shaft and is fixedly connected to this end. The first transmission wheel is coaxially arranged with the motor main shaft and is drivingly connected to the motor main shaft. The second transmission wheel is coaxially arranged with the transmission cylinder and is drivingly connected. In the embodiment shown in the figure, a key groove is provided on the transmission cylinder, and a transmission key is provided on the second transmission wheel that is engaged with the key groove on the transmission cylinder 3. The second transmission wheel drives the transmission cylinder to rotate through the cooperation of the transmission key and the key groove. The motor drives the first transmission wheel 12 to rotate, and the belt transmits power to the second transmission wheel 14, and the second transmission wheel 14 drives the transmission cylinder 3 to rotate.

[0075] The motor main shaft passes through the motor main shaft mounting hole. The motor mounting plate is connected to the first motor mounting hole through the first bolt-nut assembly and to the second motor mounting hole through the second bolt-nut assembly. The connection position of the first bolt-nut assembly on the first motor mounting hole is adjustable, and the connection position of the second bolt-nut assembly on the second motor mounting hole is adjustable. The first bolt-nut assembly includes a bolt and a nut. The bolt of the first bolt-nut assembly passes through the mounting hole of the motor mounting plate and the first motor mounting hole and then is connected and tightened with the nut. The second bolt-nut assembly includes a bolt and a nut. The bolt of the second bolt-nut assembly passes through the mounting hole of the motor mounting plate and the second motor mounting hole and then is connected and tightened with the nut, enabling the fixed installation of the motor on the mounting seat. After the nut and the bolt of the first bolt-nut assembly are loosened from each other and the nut and the bolt of the first bolt-nut assembly are loosened from each other, the motor can be moved along the first motor mounting hole and the second motor mounting hole, thereby adjusting the position of the motor on the mounting seat 7.

[0076] In some embodiments, the cigarette rod detection device further includes a pushing assembly, a clamping assembly, a fitting and a fixing member. The pushing assembly includes a second transmission part, a pushing rod 6 disposed in the barrel cavity 32, a third transmission part 63 disposed on the pushing rod 6, and a first threaded part 61 disposed on the pushing rod 6 and having a thread axis parallel to the axis of the transmission barrel. The first transmission part 33 and the second transmission part are slidably engaged along the axis of the transmission barrel, and when the transmission barrel 3 rotates, the pushing rod 6 is driven to rotate coaxially with the transmission barrel 3 through the cooperation of the first transmission part 33 and the second transmission part. Torque can be transmitted between the first transmission part 33 and the second transmission part and they can slide relative to each other. In some embodiments, one of the first transmission part and the second transmission part includes a chute, and the other includes a sliding block that cooperates with the chute. In the embodiment shown in the figure, the first transmission part includes a chute extending axially of the first cylinder body 31 provided on the first cylinder body, and the second transmission part includes an annular ring 91, a sliding column 92 fixedly connected to the annular ring 91, and a connection hole fixedly connected to the sliding column 92 provided on the pushing rod 6. In the embodiment shown in the figure, it includes a plurality of sliding columns 92 distributed circumferentially along the pushing rod and a plurality of connection holes distributed circumferentially on the pushing rod. One connection hole is fixedly connected to one sliding column 92 by means of threaded connection or the like. During operation, the transmission barrel transmits torque to the sliding column through the chute, and the sliding column transmits torque to the connection hole on the pushing rod to make the pushing rod rotate. At the same time, the sliding column can also move axially relative to the chute along the axis of the transmission barrel.

[0077] The clamping assembly includes a clamping seat 4 and a clamping member 5 mounted on the clamping seat 4. The clamping seat 4 includes a second connecting portion 41 detachably connected to the first connecting portion 34 and a fourth transmission portion 42 provided on the clamping seat 4. The third transmission portion 63 and the fourth transmission portion 42 are slidably engaged along the axial direction of the transmission cylinder. When the push rod 6 rotates, the clamping seat 4 is driven to rotate coaxially with the push rod 6 through the cooperation of the third transmission portion 63 and the fourth transmission portion 42. The cooperation between the third transmission portion 63 and the fourth transmission portion 42 is similar to the cooperation between the first transmission portion and the second transmission portion. One of them includes a chute, and the other includes a sliding block that cooperates with the chute. In the illustrated embodiment, the third transmission portion includes a chute provided on the push rod, and the fourth transmission portion 42 includes a transmission hole provided on the clamping seat 4 and a transmission pin inserted into the transmission hole and into the chute of the fourth transmission portion. The transmission pin can be slidably engaged with the chute of the fourth transmission portion. The fourth transmission portion transmits the torque to the transmission hole through the cooperation of the chute and the transmission pin, and then drives the clamping seat 4 to rotate. In this embodiment, the clamping seat 45 is detachably connected to the first connecting portion 34 through the second connecting portion 41, which can realize the convenient installation of the clamping seat 45 on the transmission cylinder and the convenient installation or separation of the clamping member and the clamping seat 45 after the clamping seat 45 is disassembled. After the clamping seat is installed on the transmission cylinder, since the push rod can reliably transmit the torque to the clamping seat 45, there is no need for a reliable torque transmission requirement between the clamping seat 45 and the transmission cylinder. Therefore, the detachable connection between the clamping seat 45 and the transmission cylinder can be set as a simple threaded connection, for example, which reduces the connection requirement and enables the convenient and simple disassembly between the clamping seat 45 and the transmission cylinder.

[0078] The clamping member 5 has a state of loading cigarettes in which the clamping cavity opens to load cigarettes and a state of clamping cigarettes in which the clamping cavity shrinks to clamp cigarettes. The clamping member 5 is used to be mounted on the clamping seat and is used to clamp cigarettes. The clamping member 5 has a clamping cavity for clamping cigarettes. In the illustrated embodiment, the clamping member 5 includes a plurality of clamping blocks, and the plurality of clamping blocks surround to form a clamping cavity for clamping cigarettes. The push rod 6 drives the clamping member 5 to switch between the state of loading cigarettes and the state of clamping cigarettes by moving in the positive direction and the reverse direction along the axial direction of the transmission cylinder 3. If the movement of the push rod 6 in one direction along its axial direction is the positive movement, then the movement in the opposite direction along its axial direction is the reverse movement opposite to the positive direction. In the illustrated embodiment, the movement of the push rod towards the direction of the clamped cigarette is the positive movement, and the movement away from the cigarette is the reverse movement. When the push rod moves in the positive direction, it drives the clamping cavity of the clamping member 5 to open, so that cigarettes can be loaded or removed. When the push rod moves in the reverse direction, it can drive the clamping cavity of the clamping member 5 to become smaller, so that the loaded cigarettes can be clamped.

[0079] The fitting 2 is rotatably arranged in the cylinder cavity 32 relative to the transmission cylinder 3 and includes a second thread portion 21 that is in threaded engagement with the first thread portion 61. The fixing member 17 is used to cooperate with the fitting 2. The fixing member 17 has a first state that restricts the fitting 2 from rotating about the axis of the thread of the first thread portion 61 and a second state that enables the fitting 2 to rotate about the axis of the thread of the first thread portion 61. In the illustrated embodiment, the fixing member includes an electromagnetic clutch. The electromagnetic clutch includes a first part and a second part that are relatively rotatable. The first part is mounted on the mounting seat 7 through the mounting bracket 16 and the mounting block 15. The second part is fixedly connected to the fitting 2. By connecting and disconnecting the first part and the second part, the fixing member 17 can be switched between the first state and the second state.

[0080] When the fixing member 17 is switched to the first state and the fitting 2 is restricted from rotating, when the push rod 6 is driven to rotate by the transmission cylinder, the push rod can produce a motion effect similar to that of a lead screw-nut mechanism through the threaded engagement between the first thread portion 61 and the second thread portion of the fitting 2, causing the push rod to move along its axis direction. When the drive assembly drives the transmission cylinder to rotate in different directions, the drive cylinder also drives the push rod to rotate in different directions. Then, the push rod will move in the positive or negative direction under the action of the second thread portion of the fitting 2 that is restricted from rotating, so as to be able to drive the clamping member to switch between the cigarette loading state and the cigarette clamping state. When the fixing member 17 is switched to the second state, the fitting 2 is not restricted from rotating. The fitting 2 can rotate about the axis of the thread of the first thread portion 61, that is, it can rotate relative to the transmission cylinder. Thus, when the push rod 6 is driven to rotate by the transmission cylinder, the fitting 2 can rotate with the push rod, the push rod does not move, and the push rod drives the clamping seat, the clamping member, and the cigarette to rotate, so that the outer peripheral surface of the cigarette can be comprehensively detected by the detection component of the cigarette detection device, such as the camera detection device 18 shown in the figure.

[0081] In the cigarette detection device of this embodiment, by switching the fixing member 17 between the first state and the second state, and by driving the transmission cylinder to rotate in different directions, the clamping member 5 can be switched between the cigarette loading state and the cigarette clamping state, so that the operations of loading the cigarette 100 and clamping the cigarette 100 can be conveniently carried out, and after the cigarette is clamped, it can automatically rotate so that different parts of the cigarette can be conveniently detected by the detection component. At the same time, the clamping seat 4 can be conveniently detachably connected to the transmission cylinder 3, so that the installation and disassembly of the clamping member 5 can be facilitated. After the clamping seat 4 is connected to the transmission cylinder 3, the clamping seat 4 can reliably drive the clamping member 5 and the cigarette to rotate coaxially with the transmission cylinder 3.

[0082] In some embodiments, the cigarette detection device further includes a limiting component for restricting the movement of the fitting 2 relative to the transmission cylinder along the axial direction of the transmission cylinder 3. In the embodiment shown in the figure, the limiting component includes a first annular groove 22 with a U-shaped cross-section of the groove body provided on the fitting 2, an annular retaining ring 23 installed on the first annular groove 22, and a second annular groove 35 with a U-shaped cross-section of the groove body provided at one end of the transmission cylinder 3. The annular retaining ring 23 is inserted into the groove body of the second annular groove 35 at the same time. The second annular groove 35 is jointly formed by the end groove 351 of the transmission cylinder 3 and the gasket 352 installed at the end of the transmission cylinder 3. When the cigarette to be clamped rotates so that all parts of its outer peripheral surface are comprehensively detected by the detection component, the fixing member 17 switches to the second state, the fitting 2 is not restricted from rotating, the fitting 2 can rotate relative to the transmission cylinder, the push rod 6 is driven to rotate by the transmission cylinder, and the fitting 2 rotates following the push rod. If the movement of the fitting is not restricted by the limiting component, the fitting 2 and the push rod may move axially, which may affect the clamping member. For example, it may cause the clamping member to switch to the state of loading cigarettes, resulting in loose cigarettes. In this embodiment, the limiting component is provided to restrict the movement of the fitting 2 relative to the transmission cylinder along the axial direction of the transmission cylinder 3, which can restrict the axial movement of the fitting and the push rod when the cigarette is rotated and detected, and avoid interference of the push rod and the fitting on the clamping member.

[0083] In some embodiments, the first connecting portion 34 and the second connecting portion 41 are detachably connected by screw fitting.

[0084] In some embodiments, as shown in the figure, the clamping seat 4 includes a plurality of guiding holes 43 extending radially. The clamping member 5 includes a plurality of clamping blocks 51. The clamping block 51 includes a moving part 511 extending into the clamping seat 4 and mating with the guiding holes 43 one by one, and a clamping part extending out of the clamping seat 4 for clamping cigarette rods. The guiding holes 43 extend radially along the clamping seat 4. In the embodiment shown in the figure, the guiding holes 43 penetrate the clamping seat 4 radially. In some embodiments not shown in the figure, the guiding holes 43 may not penetrate the clamping seat 4 and only extend radially along the clamping seat 4 to the middle of the wall of the clamping seat 4 and then stop extending. The moving part 511 of each clamping block 51 mates with one guiding hole 43 and can move radially along the clamping seat relative to the guiding hole 43. When the push rod 6 moves in the direction close to the clamping part, it simultaneously pushes the moving parts 511 of the plurality of clamping blocks 51 to move radially outward along the guiding holes 43 that the moving parts 511 mate with, so that the clamping member 5 switches to the cigarette rod loading state. The clamping assembly further includes an elastic member mating with the moving parts 511 of the plurality of clamping blocks 51. The elastic force of the elastic member causes the moving parts 511 of the plurality of clamping blocks 51 to tend to move radially inward along the clamping seat 4. The elastic member includes, for example, an elastic ring. In the embodiment where the guiding hole 43 penetrates the clamping seat 4 radially as shown in the figure, a first mounting groove 513 is further provided on the moving part of the clamping block, and an annular second mounting groove 44 is provided on the clamping seat. After the clamping block is mounted on the clamping seat, the annular elastic ring is mounted on the second mounting groove and simultaneously mounted on the first mounting groove 513, and the elastic force of this elastic ring seems to point radially inward of the elastic ring. After the cigarette rods are loaded into the clamping cavity, after the push rod leaves the clamping block, the elastic force of the elastic ring causes the clamping block to move radially inward along the clamping seat, so that the clamping block clamps the cigarette rods. When the push rod moves in the direction close to the clamping block, the push rod pushes the clamping block to overcome the elastic force of the elastic ring, so that the clamping block moves radially outward along the clamping seat, and the clamping member switches to the cigarette rod loading state.

[0085] In some embodiments, the clamping seat 4 includes a second cylinder 451 and an annular disc 452 located at the end face of the cylinder. The guiding hole 43 includes a strip-shaped through hole provided on the second cylinder 451, that is, a strip-shaped through hole penetrating the second cylinder 451 radially along the clamping seat. The moving part 511 is inserted into the strip-shaped through hole, and the protruding part 512 protrudes from the through hole in the middle of the annular disc out of the clamping seat 4. The moving part 511 and the protruding part 512 are connected by a stepped surface. In the embodiment shown in the figure, the stepped surface extends into the guiding hole 43, and the guiding hole 43 guides the movement of the moving part in the guiding hole through contact with the stepped surface, so that the clamping seat can stably switch between the cigarette rod loading state and the cigarette rod clamping state.

[0086] In some embodiments, as shown in the figure, at least one of the surface of the push rod 6 cooperating with the moving part 511 and the surface of the moving part 511 cooperating with the push rod is a wedge surface. In the embodiment shown in the figure, both the surface of the push rod 6 and the surface of the moving part 511 are wedge surfaces at the mating position. As shown in the figure, the end of the push rod is a tapered part, and the outer surface of the tapered part is an inclined surface. The movement of the push rod can reliably push the moving part 511 to move radially along the clamping seat through the action of the wedge surface.

[0087] In some embodiments, as shown in the figure, the cigarette rod detection device further includes a controller and a bearing seat assembly. The bearing seat assembly includes a bearing seat 8 and a bearing disposed within the bearing seat. The transmission cylinder 3 is mounted within the bearing seat through the bearing. In the embodiment shown in the figure, it includes a first bearing 93 and a second bearing 94. The bearing seat is provided with a first bearing cavity 831 and a second bearing cavity 832. The first bearing 93 and the second bearing 94 are respectively mounted within the first bearing cavity 831 and the second bearing cavity 832. Both ends of the transmission cylinder 3 are mounted on the bearing seat through the first bearing 93 and the second bearing 94. The bearing seat is further provided with a position detection sensor signal-connected to the controller. The position detection sensor is used to detect the position of the push rod 6. In this embodiment, by providing the detection sensor, the position of the push rod 6 along the axial direction of the transmission cylinder can be detected, so as to determine whether the push rod plays a pushing role on the clamping member at this time, and the state of the clamping member can be judged. In some embodiments, the size of the clamping cavity of the clamping member can also be adjusted by detecting and controlling the axial position of the push rod 6, and the magnitude of the clamping force for clamping the cigarette rod can be controlled.

[0088] In some embodiments, the first transmission part 33 includes a strip-shaped hole provided on the first cylinder body 31. The second transmission part includes an annular ring 91 disposed around the transmission cylinder 3 and a sliding column 92 that is slidably engaged with the strip-shaped hole and fixedly connected to the push rod 6 and the annular ring. The position detection sensor is used to detect the position of the annular ring 91. In the embodiment shown in the figure, the sliding column 92 is provided with a screw hole, and the annular ring is provided with a countersunk hole. The annular ring and the sliding column 92 can be connected by screwing a screw through the countersunk hole of the annular ring and the screw hole of the sliding column 92. Since the annular ring 91 is fixedly connected to the push rod through a sliding block, detecting the axial position of the annular ring can reflect the axial position of the push rod.

[0089] In some embodiments, the bearing seat includes a mounting hole 82 located radially outside the annular ring 91. The position detection sensor includes a first photoelectric detection switch 811 and a second photoelectric detection switch 812 disposed in the mounting hole 82. Along the axis direction of the transmission cylinder 3, the annular ring 91 is located between the first photoelectric detection switch 811 and the second photoelectric detection switch 812. The first photoelectric detection switch 811 and the second photoelectric detection switch 812 can be axially arranged at corresponding positions of the axial extreme positions of the push rod. When the push rod moves in the positive or negative axial direction and is detected by the first photoelectric detection switch 811 or the second photoelectric detection switch 812, it means that the push rod has reached the restricted movement position along the axis. Thus, the controller can stop the rotation of the transmission cylinder and make the push rod stop moving. The positions of the first photoelectric detection switch 811 and the second photoelectric detection switch 812 along the axis of the transmission cylinder can be adjusted, so that the restricted movement position of the push rod along the axis can be adjusted.

[0090] In some embodiments, as shown in the figure, the cigarette detection device further includes a dust-proof cover 95. The dust-proof cover is in threaded fit with the bearing seat and surrounds the clamping assembly. The dust-proof cover 95 surrounds the clamping assembly, which can play a role in protecting the cigarette detection device from dust entry and help ensure the long-term reliable operation of the cigarette detection device.
