[0044] As Figure 1 shown, in this embodiment, a cigarette clamping device is provided, which includes a first clamping member 1 and a second clamping member 2. The first clamping member 1 and the second clamping member 2 are sealingly connected and slidably connected. The cigarette 3 is clamped between the first clamping member 1 and the second clamping member 2. One end of the cigarette 3 abuts against the second clamping member 2. The sliding direction of the first clamping member 1 and / or the sliding direction of the second clamping member 2 is parallel to the length direction of the cigarette 3.

[0045] As Figure 1As shown, since the first clamping member 1 and the second clamping member 2 are slidably connected, and the sliding direction of the first clamping member 1 and / or the sliding direction of the second clamping member 2 is parallel to the length direction of the cigarette 3. When the lengths of the cigarettes 3 are different, the relative positions of the first clamping member 1 and the second clamping member 2 can be slidably adjusted, so that cigarettes 3 of different lengths can be clamped. Since one end of the cigarette 3 abuts against the second clamping member 2, the second clamping member 2 can limit the position of the cigarette 3 to prevent the cigarette 3 from coming out in the direction away from the first clamping member 1 (for example, preventing the cigarette 3 from coming out to the right).

[0046] As Figure 1 shown, a third sealing ring 13 can be provided at the right end of the first clamping member 1. The right end of the first clamping member 1 can be sealingly and slidably connected to the left end of the second clamping member 2 in a hole-shaft fit manner. The first clamping member 1 can slide left and right relative to the second clamping member 2. The right end face of the cigarette 3 can abut against the second clamping member 2. The third sealing ring 13 can be an O-ring.

[0047] As Figure 1 shown, optionally, the first clamping member 1 includes a first housing 10, a second housing 11 and a first sealing ring 12. The first sealing ring 12 is located in the accommodation cavity formed by the first housing 10 and the second housing 11. The first housing 10 and the second housing 11 are connected. The second housing 11 is sealingly connected to the second clamping member 2 and is slidably connected to the second clamping member 2. The cigarette 3 is clamped by the first sealing ring 12, and the cigarette 3 is sealingly connected to the first sealing ring 12.

[0048] As Figure 1 shown, the first housing 10, the second housing 11 and the first sealing ring 12 can be coaxially arranged. The outer side wall of the first sealing ring 12 can abut against the inner side wall of the first housing 10. The first housing 10 and the second housing 11 can be connected by screwing or clamping. The first sealing ring 12 can be a labyrinth ring, and its material can be a soft material such as rubber or silica gel. That is, the first sealing ring 12 can be a soft sealing ring. The number of the first sealing rings 12 can be multiple, and the multiple first sealing rings 12 can be abutted in sequence.

[0049] As Figure 1 shown, a third sealing ring 13 can be sleeved on the right end of the second housing 11. The right end of the second housing 11 can be inserted into the left end of the second clamping member 2. The right end of the second housing 11 and the left end of the second clamping member 2 can be slidably and sealingly connected in a hole-shaft fit manner.

[0050] As Figure 1As shown, the left end of the cigarette rod 3 can be inserted and clamped along its length direction in the first sealing ring 12. The cigarette rod 3 and the first sealing ring 12 can be hermetically connected by an interference fit. The right end face of the first sealing ring 12 can abut against the left end face of the second housing 11 (when there are multiple first sealing rings 12, the right end face of the rightmost first sealing ring 12 abuts against the left end face of the second housing 11). A limiting ring 100 can be arranged at the left end of the first housing 10, and the inner diameter of the limiting ring 100 is smaller than the outer diameter of the first sealing ring 12. With such an arrangement, it can be prevented that when the cigarette rod 3 is pulled out to the left, the first sealing ring 12 is driven to disengage from the first housing 10. When the first sealing ring 12 is a soft sealing ring, the diameter of the cigarette rod 3 can be larger than the diameter of the central hole of the first sealing ring 12, and the cigarette rod 3 can squeeze the central hole of the first sealing ring 12 to achieve an interference fit between the cigarette rod 3 and the first sealing ring 12.

[0051] Please also refer to Figure 1 and Figure 2 , optionally, the second housing 11 includes a through hole 110, the cigarette rod 3 is inserted through the through hole 110, the diameter of the through hole 110 is larger than the diameter of the cigarette rod 3, and the outer diameter of the first sealing ring 12 is larger than the diameter of the through hole 110. The through hole 110 can be coaxially arranged with the cigarette rod 3. Since the outer diameter of the first sealing ring 12 is larger than the diameter of the through hole 110, the first sealing ring 12 can be sealed by using the left end face of the second housing 11, reducing the error in the suction resistance test of the cigarette rod 3. The diameter of the through hole 110 being larger than the diameter of the cigarette rod 3 can prevent the cigarette rod 3 from being blocked by the second housing 11 when inserted.

[0052] Please also refer to Figure 1 and Figure 3 , optionally, the first sealing ring 12 includes a first recess 120, the cigarette rod 3 is clamped in the first recess 120, and the cigarette rod 3 and the first recess 120 are hermetically connected. The insertion direction of the cigarette rod 3 can be the same as the recess direction of the first recess 120. For example, the first recess 120 can be recessed to the right. When the number of the first sealing rings 12 is multiple, the orientations of the first recesses 120 of each first sealing ring 12 can be the same. The first recess 120 can be coaxially arranged with the first sealing ring 12. By providing the first recess 120 in the first sealing ring 12, the thickness of the first sealing ring 12 can be reduced, making it easier for the cigarette rod 3 to be inserted through the first sealing ring 12.

[0053] Such as Figure 1As shown, optionally, the second clamping member 2 includes a third housing 20 and a second sealing ring 21. The second sealing ring 21 is located inside the third housing 20. The second housing 11 and the third housing 20 are sealingly connected and slidably connected. The cigarette rod 3 is clamped in the second sealing ring 21, and the cigarette rod 3 and the second sealing ring 21 are sealingly connected. The third housing 20 and the second sealing ring 21 can be coaxially arranged. The second sealing ring 21 can be a labyrinth ring, and its material can be a soft material such as rubber or silica gel. That is, the second sealing ring 21 can be a soft sealing ring. The number of the second sealing rings 21 can be multiple, and the multiple second sealing rings 21 can be abutted in sequence.

[0054] As Figure 1 shown, a third sealing ring 13 can be sleeved on the right end of the second housing 11. The right end of the second housing 11 can be inserted into the left end of the third housing 20. The right end of the second housing 11 and the left end of the third housing 20 can be slidably and sealingly connected by means of hole-shaft fit. The right end of the cigarette rod 3 can be inserted and clamped in the second sealing ring 21 along its length direction. The cigarette rod 3 and the second sealing ring 21 can be sealingly connected by means of interference fit. For example, when the second sealing ring 21 is a soft sealing ring, the diameter of the cigarette rod 3 can be larger than the diameter of the central hole of the second sealing ring 21, and the cigarette rod 3 can squeeze the central hole of the second sealing ring 21 to achieve the interference fit between the cigarette rod 3 and the second sealing ring 21.

[0055] As Figure 1 shown, the specifications (including shape, size, material, etc.) of the second sealing ring 21 and the first sealing ring 12 can be the same. The central hole diameters of the first sealing ring 12 and the second sealing ring 21 can be replaced according to the diameter of the cigarette rod 3 to adapt to cigarette rods 3 of different diameters. For example, before the draw resistance test of the cigarette rod 3, a variety of first sealing rings 12 and second sealing rings 21 with different central hole diameters can be prepared (the outer diameters of the first sealing ring 12 and the second sealing ring 21 can be kept the same). In this way, when the diameter of the cigarette rod 3 changes, the first sealing ring 12 and the second sealing ring 21 corresponding to the diameter of the cigarette rod 3 can be replaced.

[0056] As Figure 1 shown, optionally, the third housing 20 includes a limiting portion 200, and the second sealing ring 21 abuts against the limiting portion 200. The limiting portion 200 can be annular. The left end face of the second sealing ring 21 can abut against the limiting portion 200 (when there are multiple second sealing rings 21, the left end face of the leftmost second sealing ring 21 abuts against the limiting portion 200). The setting of the limiting portion 200 can prevent the second sealing ring 21 from moving along with the cigarette rod 3 when the cigarette rod 3 is pulled out to the left.

[0057] Please also refer to Figure 1 and Figure 4, Optionally, the second sealing ring 21 includes a second recess 210. The cigarette rod 3 is clamped in the second recess 210, and the cigarette rod 3 and the second recess 210 are sealingly connected. The insertion direction of the cigarette rod 3 can be the same as the recess direction of the second recess 210. For example, the second recess 210 can be recessed to the right. When the number of the second sealing rings 21 is multiple, the orientations of the second recesses 210 of the respective second sealing rings 21 can be the same. The second recess 210 can be coaxially arranged with the second sealing ring 21. By providing the second recess 210 in the second sealing ring 21, the thickness of the second sealing ring 21 can be reduced, making it easier for the cigarette rod 3 to pass through the second sealing ring 21.

[0058] As Figure 1 shown, optionally, the second clamping member 2 further includes a socket member 22. The socket member 22 is connected to the third housing 20. The second sealing ring 21 abuts against the socket member 22, and the second sealing ring 21 is located in the accommodation cavity formed by the socket member 22 and the third housing 20. The outer sidewall of the second sealing ring 21 can abut against the inner sidewall of the third housing 20. The socket member 22 and the third housing 20 can be connected by screwing or clamping. The right end face of the second sealing ring 21 can abut against the left end face of the socket member 22 (when the number of the second sealing rings 21 is multiple, the right end face of the rightmost second sealing ring 21 abuts against the left end face of the socket member 22). A perforation can be provided at the center of the socket member 22, and the perforation communicates with the soft washer 23. The socket member 22 is connected to the pressure drop detection device, and the pressure drop detection device sucks through the perforation to detect the draw resistance of the cigarette rod 3.

[0059] As Figure 1 shown, optionally, the second clamping member 2 further includes a soft washer 23. The soft washer 23 is located in the accommodation cavity formed by the socket member 22 and the third housing 20. The second sealing ring 21, the soft washer 23 and the socket member 22 abut against each other in sequence, and one end of the cigarette rod 3 abuts against the soft washer 23. The material of the soft washer 23 can be a soft material such as neoprene or silica gel. The right end face of the cigarette rod 3 can abut against the left end face of the soft washer 23. The right end face of the second sealing ring 21 abuts against the left end face of the soft washer 23 (when the number of the second sealing rings 21 is multiple, the right end face of the rightmost second sealing ring 21 abuts against the left end face of the soft washer 23). The soft washer 23 can be coaxially arranged with the socket member 22. The outer diameter of the soft washer 23 can be larger than the diameter of the cigarette rod 3. By providing the soft washer 23, when the cigarette rod 3 is being sucked, it can play a buffering role for the cigarette rod 3 and prevent the cigarette rod 3 from deforming when being sucked.

[0060] Please also refer to Figure 1 and Figure 5, Optionally, the socket component 22 includes a counterbore 220, the soft gasket 23 is embedded in the counterbore 220, and the second sealing ring 21 abuts against the edge of the counterbore 220. The counterbore 220 can be arranged at the left end of the socket component 22. The diameter of the counterbore 220 is the same as the outer diameter of the soft gasket 23. The depth of the counterbore 220 can be the same as the thickness of the soft gasket 23. The counterbore 220 can be coaxially arranged with the through hole. Embedding the soft gasket 23 in the counterbore 220 can facilitate the positioning of the soft gasket 23. That is, when assembling the socket component 22, the soft gasket 23 can be first embedded into the counterbore 220, and then the socket component 22 with the soft gasket 23 is connected to the third housing 20.

[0061] Please also refer to Figure 1 and Figure 5 , when assembling the cigarette holder device, the first sealing ring 12 can be first embedded into the first housing 10, and then the left end of the second housing 11 is screwed into the first housing 10. The second sealing ring 21 is embedded into the third housing 20, the soft gasket 23 is embedded into the counterbore 220, and then the socket component 22 with the soft gasket 23 is screwed into the third housing 20. Finally, the right end of the first clamping component 1 is slidably embedded into the left end of the second clamping component 2.

[0062] Please also refer to Figure 1 and Figure 5 , corresponding to a cigarette 3 of a specific length, after the first clamping component 1 and the second clamping component 2 are slid and adjusted in place, the cigarette 3 can be inserted into the cigarette holder device from left to right. When the right end face of the cigarette 3 abuts against the left end face of the soft gasket 23, then the pressure drop detection device is turned on to suck the cigarette 3 from the socket component 22 to perform a draw resistance test on the cigarette 3. The sliding frictional force between the second housing 11 and the third housing 20 should be greater than the draw resistance of the cigarette 3. In this way, when performing the draw resistance test on the cigarette 3, the cigarette 3 will not drive the first clamping component 1, and the first clamping component 1 and the second clamping component 2 can remain relatively stationary.
