[0002] Before the tobacco is rolled, it will be stored in the warehouse through the tobacco box, and will be taken out for use when it is rolled. When the tobacco is loaded into the tobacco box through the packaging station, it has a certain temperature. After the tobacco is loaded, the tobacco box is not full, and there is a certain amount of air inside. There is moisture in the air. When the hot and humid air in the packaged tobacco box acts on the inner wall of the tobacco box and cools down, condensation will form on the inner wall of the tobacco box. After the existing tobacco box is sealed, it is difficult to evacuate the interior, so that the hot and humid air in the tobacco box will form condensation on the inner wall of the tobacco box, affecting the quality of the tobacco. Summary of the invention

[0009] Furthermore, the conduction device for extracting air from a tobacco box further comprises a second sliding member, which is slidably arranged on the inner sleeve, the second sliding member is provided with a second blocking member at an end close to the air inlet, and a second elastic member is provided between the second sliding member and the conduction chamber so that the second sliding member and the second blocking member thereon have a tendency to move toward the air inlet under the action of the second elastic member so that the second blocking member can block the air inlet;

[0010] The first sliding member and / or the first blocking member are provided with an abutment block so that when the first sliding member and the first blocking member thereon move away from the conducting port, the abutment block can act on the second sliding member and drive the second sliding member to move, thereby driving the second blocking member on the second sliding member to move away from the air inlet.

[0011] Furthermore, the second blocking member is a sheet structure vertically arranged on the second sliding member, and a mounting groove is provided on the bottom surface of the conductive body, and the mounting groove is connected to the air inlet.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0036] The first embodiment of the present invention refers to Figures 1 to 7 , a conduction device for exhausting air from a tobacco box is provided, the conduction device comprising a conduction body 10, a first sliding member 31, a first blocking member 41, a first elastic member 51 and an inner sleeve 20, etc.

[0037] The conducting body 10 is fixedly mounted on the cover of the tobacco box when in use. In a preferred embodiment, the conducting body 10 is an overall cylindrical structure, and a mounting plate 111 is provided at the bottom thereof. When the conducting body 10 is mounted on the cover of the tobacco box, a through groove and a side groove are provided at the cover of the tobacco box. The mounting plate 111 is fixedly mounted in the through groove by bolts, and the side facing the inside of the tobacco box is flush with the side wall of the cover of the tobacco box. The through groove is connected with the side groove and penetrates to the outside of the cover of the tobacco box. The conducting body 10 is matched and mounted in the through groove, and the outward end of the conducting body 10 can be connected to the outside. The outward end of the conducting body 10 can be flush with the outer wall of the cover, or it can be concave in the outer wall of the cover, or it can be convex in the outer wall of the cover, which can be selected according to actual use.

[0038] The conducting body 10 has a conducting chamber 11, and an air inlet 12 connected to the conducting chamber 11 is opened at the bottom of the conducting body 10, and a conducting port 13 connected to the conducting chamber 11 is opened at the top of the conducting body 10. At this time, the air inlet 12 and the conducting port 13 are connected through the conducting chamber 11, and can form an outlet channel for air to pass through.

[0039] The inner sleeve 20 is fixedly disposed in the conduction chamber 11. The inner sleeve 20 is a cylindrical structure, the bottom of which is fixedly connected to the side wall of the conduction body 10 at the conduction chamber 11, and the top is open, and the top opening of the inner sleeve 20 faces the conduction port 13. In this exemplary embodiment, there are multiple air inlets 12, and the multiple air inlets 12 are distributed around the circumference with the axis of the inner sleeve 20 as the center, so as to achieve multi-point air intake through the multiple air inlets 12.

[0040] The first sliding member 31 is a cylindrical structure as a whole and is slidably disposed inside the inner sleeve 20. The first sliding member 31 is provided with a first blocking member 41 at the end thereof facing the conducting port 13, and a first elastic member 51 is disposed between the first sliding member 31 and the conducting chamber 11 so that the first sliding member 31 and the first blocking member 41 thereon have a tendency to move toward the conducting port 13 under the action of the first elastic member 51 so that the first blocking member 41 can block the conducting port 13, and when the first blocking member 41 is pressed, the first blocking member 41 can move away from the conducting port 13, and at this time, the conducting port 13 is connected to the conducting chamber 11. The first elastic member 51 is preferably a compression spring, which is located inside the first sliding member 31 and the inner sleeve 20.

[0041] When implementing, please refer to Figure 8 and Fig. 9 In an exemplary embodiment, after the tobacco is loaded into the tobacco box, the box cover is closed, at this time, a relatively closed space is formed in the tobacco box, and then the exhaust head 70 of the exhaust device is inserted into the conduction device. Figure 8 and Fig. 9 As shown, if the suction tube 71 of the suction head 70 of the suction device is inserted into the conductive body 10, and the first blocking member 41 is driven to move the first blocking member 41 away from the conductive port 13, at this time, the conductive port 13 is connected to the conductive chamber 11, and the suction channel 72 of the suction tube 71 is connected to the conductive chamber 11, then the suction device starts to suck air, and the air inside the tobacco box enters the conductive chamber 11 through the air inlet 12, and then is sucked out by the suction tube, so as to partially extract the air in the tobacco box in this way; after part of the gas is extracted, the suction tube is slowly extracted, and the suction can be continued during the extraction process, and the first blocking member 41 moves toward the conductive port 13 under the action of the first elastic member 51 and finally blocks the conductive port 13, as shown in FIG. Figure 3 As shown, at this time, the tobacco box is isolated from the outside world, and the outside air cannot enter the tobacco box, so that most of the air in the tobacco box is extracted and has a certain degree of vacuum. Since most of the air is extracted, the problem of condensation on the inner wall of the tobacco box can be greatly alleviated, and the condensation inside the tobacco box can be reduced as much as possible or even completely avoided, keeping the inside of the tobacco box dry, and ensuring the quality of tobacco in the tobacco box.

[0042] The conduction device also includes a second sliding member 32, which is a cylindrical structure and is slidably arranged on the outside of the inner sleeve 20. The second sliding member 32 is provided with a second blocking member 42 at the end near the air inlet 12, and a second elastic member 52 is provided between the second sliding member 32 and the conduction chamber 11 so that the second sliding member 32 and the second blocking member 42 thereon have a tendency to move toward the air inlet 12 under the action of the second elastic member 52 so that the second blocking member 42 can block the air inlet 12. At this time, the air inlet 12 is blocked by the second blocking member 42, and the inside of the tobacco box is not connected to the conduction chamber 11, and air cannot flow between the two. The second elastic member 52 is preferably a compression spring, located on the outside of the second sliding member 32, and the end of the second sliding member 32 is provided with a convex edge to abut the end of the second elastic member 52 through the convex edge. The number of second blocking members 42 is consistent with the number of air inlets 12 and corresponds one to one, that is, one second blocking member 42 is used to block one air inlet 12.

[0043] The first sliding member 31 is provided with an abutment block 60 so that when the first sliding member 31 and the first blocking member 41 thereon move away from the conducting port 13, the abutment block 60 can act on the second sliding member 32 and drive the second sliding member 32 to move, thereby driving the second blocking member 42 on the second sliding member 32 to move away from the air inlet 12. During implementation, when the first blocking member 41 is pressed and moves away from the conducting port 13, the abutment block 60 acts on the second sliding member 32 and drives the second sliding member 32 to move, so as to drive the second blocking member 42 on the second sliding member 32 to move away from the air inlet 12. At this time, the air inlet 12 is open, and air can flow between the inside of the tobacco box and the conducting chamber 11, that is, the air inside the tobacco box can be exhausted; and when the pressure of the first blocking member 41 is gradually released, the first blocking member 41 moves toward the conducting port 13 under the action of the first elastic member 51, and the second sliding member 32 is reset under the action of the second elastic member 52, driving the second blocking member 42 to move toward the air inlet 12 and finally allowing the second blocking member 42 to block the air inlet 12. By setting up the second blocking member 42 and cooperating with the movement of the first sliding member 31, the first blocking member 41, etc., the second blocking member 42 can block and release the blockage of the air inlet 12. When the air inlet 12 is blocked by the second blocking member 42, on the one hand, it can isolate the gas from entering the tobacco box through the air inlet 12, and on the other hand, it can prevent tobacco from entering the conducting chamber 11.

[0044] In a preferred embodiment. The second blocking member 42 is a sheet-like structure vertically arranged on the second sliding member 32. A placement groove 14 is provided on the bottom surface of the conducting body 10. The placement groove 14 is provided on the bottom surface of the mounting plate 111. The placement groove 14 is connected to the air inlet 12. The second blocking member 42 is matched and arranged in the placement groove 14 and the air inlet 12 and moves from the outside to the inside to block the air inlet 12. The outer peripheral contour of the second blocking member 42 is just equal to the outer peripheral contour of the placement groove 14 and the air inlet 12 to achieve a dense blockage. The second blocking member 42 moves from the outside to the inside to block the air inlet 12 and acts on the bottom of the placement groove 14. At this time, under the action of the second elastic member 52, the second blocking member 42 has a tendency to move inward (in the direction of the conducting chamber 11), but cannot continue to move due to the limit action of the bottom of the placement groove 14. In a preferred embodiment, when the second sealing member 42 abuts against the bottom of the mounting groove 14, the other side of the second sealing member 42 is flush with the bottom surface of the conductive body 10. If a mounting plate 111 is provided, it is flush with the bottom surface of the mounting plate 111, so that it can be flush with the inner wall of the tobacco box when installed on the tobacco box.

[0045] When the first blocking member 41 blocks the conducting port 13 and the second blocking member 42 blocks the air inlet 12, there is a certain gap between the abutment block 60 and the second blocking member 42. The space through the gap allows the first blocking member 41 to move toward the conducting port 13 under the action of the first elastic member 51 when the pressure on the first blocking member 41 is gradually released, and the second blocking member 42 moves toward the air inlet 12. This ensures that the second blocking member 42 blocks the air inlet 12 first, and then the first elastic member 51 blocks the conducting port 13, thereby ensuring that the air inlet 12 and the conducting port 13 are blocked.

[0046] The conducting opening 13 is a circular through hole, and the first blocking member 41 is a hemispherical structure, with the spherical surface facing the conducting opening 13 and directly facing the conducting opening 13, and the conducting opening 13 is blocked by the hemispherical surface of the first blocking member 41. The hemispherical surface of the first blocking member 41 has a certain degree of flexibility at the surface, so as to achieve a more compact blockage.

[0047] The conducting body 10 further comprises a buffer chamber 15, which is located on a side of the conducting port 13 away from the conducting chamber 11 and communicates with the conducting port 13. The buffer chamber 15 is provided with an insertion opening 16 communicating with the outside on a side facing the conducting port 13. A sliding sleeve 17 is arranged in the buffer chamber 15, and the sliding sleeve 17 can penetrate the conducting port 13 and the insertion opening 16. A third elastic member 53 is arranged between the sliding sleeve 17 and the buffer chamber 15 so that the sliding sleeve 17 can be inserted into the conducting port 13 and the insertion opening 16. One end of the movable sleeve 17 is located in the insertion opening 16 under the action of the third elastic member 53 so that the sliding sleeve 17 can block the insertion opening 16, and when the sliding sleeve 17 is pressed inward, it can pass through the conducting opening 13 to abut and press the first blocking member 41 to move the first blocking member 41 away from the conducting opening 13 to release the blocking of the conducting opening 13 by the first blocking member 41. At this time, the conducting chamber 11 is connected with the buffer chamber 15 through the sliding sleeve 17. By setting the buffer chamber 15 and the sliding sleeve 17, when the air extraction cannula is inserted, the sliding sleeve 17 is driven to move a certain distance and then press the first blocking member 41 to move the first blocking member 41 away from the conduction port 13 to release the blocking of the conduction port 13 by the first blocking member 41. At this time, the sliding sleeve 17 leaves the insertion port 16, and the buffer chamber 15 is connected to the outside, and the end of the air extraction cannula enters the buffer chamber 15, and the air extraction channel of the air extraction cannula is connected to the buffer chamber 15, so that air extraction can be achieved at this time. After the air extraction is completed, the air extraction cannula is pulled out, and under the action of the third elastic member 53, one end of the sliding sleeve 17 is located in the insertion port 16 so that the sliding sleeve 17 can block the insertion port 16, and another layer of isolation can be achieved at this time. In a preferred embodiment, when the outer end of the sliding sleeve 17 blocks the insertion port 16, the outer end surface of the sliding sleeve 17 is flush with the outer side surface of the conduction body 10. The third elastic member 53 is preferably a compression spring, which is located outside the sliding sleeve 17 . A convex edge is provided at the end of the sliding sleeve 17 to abut against the end of the third elastic member 53 through the convex edge.

[0048] In a preferred implementation, the outer diameter of the suction cannula is equal to or slightly smaller than the inner diameter of the insertion opening 16, so that when the suction cannula enters the insertion opening 16, it can abut against the inner wall of the insertion opening 16 as much as possible, so that when suction is performed, the air in the tobacco box is mainly extracted.

[0049] The sliding sleeve 17 has a plurality of side wall through holes 18 connected to the interior on its side wall, so that when the sliding sleeve 17 presses the first blocking member 41 to release the blocking of the conducting port 13 by the first blocking member 41, the conducting chamber 11 is connected to the buffer chamber 15 through the sliding sleeve 17 and the side wall through holes 18 thereon.

[0050] By providing the buffer chamber 15 and the sliding sleeve 17, not only can an extra layer of sealing be achieved, but the sliding sleeve 17 slides a certain distance and then abuts against the first sealing member 41, which can play a certain role in preventing accidental touches, and also will not drive the first sealing member 41 and the second sealing member 42 when an external device accidentally touches it and does not press it deeply; at the same time, it can keep the suction tube and the like as far away from the inside of the tobacco box as possible to avoid contamination of the tobacco box when the suction tube is shared.

[0051] The second embodiment of the present invention refers to Figures 1 to 10 , an exhaust assembly is provided, including an exhaust head 70 and a conduction device 80 of the above embodiment. The exhaust head 70 includes an exhaust pipe 71, and the exhaust pipe 71 has an exhaust channel 72. In this exemplary embodiment, the exhaust channel 72 is connected to the side of the exhaust pipe 71, so that when the exhaust pipe 71 is inserted into the conduction device and drives the first blocking member 41 to move away from the conduction port 13, the exhaust channel of the exhaust pipe 71 can be connected to the conduction chamber 11. During implementation, the exhaust head 70 can be installed on a driving mechanism such as a robot hand, and connected to an external negative pressure device to provide exhaust power to achieve exhaust. The exhaust pipe 71 is driven by the exhaust head 70 to enter the conduction device, and the first blocking member 41 is driven to move away from the conduction port 13, so that the exhaust channel 72 of the exhaust pipe 71 can be connected to the conduction chamber 11, thereby helping to achieve exhaust inside the tobacco box.

[0052] In a preferred implementation, the outer diameter of the suction tube 71 is equal to or slightly smaller than the inner diameter of the passage 13, so that when the suction tube enters the passage 13, it can abut the inner wall of the passage 13 as much as possible, so that when suction is performed, the air in the tobacco box is mainly extracted.

[0053] When an insertion port 16 is provided, the exhaust tube 71 is in a form of entering the insertion port 16. In a preferred implementation, the outer diameter of the exhaust tube 71 is equal to or slightly smaller than the inner diameter of the insertion port 16, so that after the exhaust tube enters the insertion port 16, it can abut against the inner wall of the insertion port 16 as much as possible, so that when exhausting, the air in the tobacco box is mainly extracted.

[0054] In a preferred embodiment, the air extraction head 70 further includes a sealing cover 73, which is arranged on the periphery of the air extraction cannula 71, and when the air extraction cannula 71 is inserted into the conduction device, the open end of the sealing cover 73 fits the conduction device or the tobacco box so that a relatively closed space is formed inside the sealing cover 73. Considering that the outer diameter of the air extraction cannula 71 is equal to or slightly smaller than the inner diameter of the conduction port 13, or the outer diameter of the air extraction cannula 71 is equal to or slightly smaller than the inner diameter of the insertion port 16, and the positioning requirements for the tobacco box are strict, by providing the sealing cover 73, the outer diameter of the air extraction cannula 71 can be made smaller than the conduction port 13 or the insertion port 16 to a greater extent, so as to facilitate better insertion therein, and under the sealing effect of the sealing cover 73, it can be ensured that the air in the tobacco box is extracted.

[0055] The third embodiment of the present invention refers to Figures 1 to 9 as well as Fig.11 , a tobacco box is provided, the tobacco box 100 includes the conduction device 80 of the above embodiment, and the conduction device 80 is arranged on the tobacco box 100 to facilitate the exhaust of the inside of the tobacco box 100. The tobacco box 100 includes a box body 101 and a box cover 102, and the conduction device 80 is installed on the box cover 102. After the box body 101 is loaded with tobacco, the box cover 102 is covered on the box body 101 and the tobacco box 100 is formed into a closed space as much as possible to avoid gas from entering and exiting and contaminating the tobacco. At the same time, in order to avoid or reduce condensation inside the tobacco box, one way is to vacuum the inside of the tobacco box, that is, to extract part of the air. The tobacco box of the present invention is equipped with a conduction device, which can facilitate the partial extraction of air in the tobacco box. After part of the gas is extracted, the conduction port and other channels can be blocked. At this time, the tobacco box is isolated from the outside world, and the outside air cannot enter the tobacco box, so that most of the air in the tobacco box is extracted and has a certain vacuum degree. Since most of the air is extracted, the problem of condensation on the inner wall of the tobacco box can be greatly alleviated, and the condensation inside the tobacco box can be reduced as much as possible or even completely avoided, so as to keep the inside of the tobacco box dry and ensure the quality of tobacco in the tobacco box.

[0056] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention.
