Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0034] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0035] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0036] like Figures 1-4 As shown, this embodiment provides a smoke exhaust device for a filter-type cigarette laboratory, including a suction box 1, a deformable regulating pipe 2, a connecting pipe 3, a filter 4, and a centrifuge 5 arranged in sequence. The air outlet of the centrifuge 5 is connected to the smoke exhaust pipe.
[0037] In one embodiment, the third direction is a vertical direction, the first direction and the second direction are horizontal directions, and the first direction, the second direction and the third direction are perpendicular to each other.
[0038] The connecting pipe 3, filter 4 and centrifuge 5 are arranged along the first direction, the suction box 1, regulating pipe 2 and connecting pipe 3 are arranged along the third direction, and the suction box 1, regulating pipe 2 and connecting pipe 3 are arranged from bottom to top.
[0039] Filter 4 is a filter cartridge with an internal filter element such as activated carbon. The air inlet pipe of centrifuge 5 is connected to the filter cartridge, and the air outlet is connected to the exhaust pipe. Through the action of centrifuge 5, the intake air first enters the filter cartridge, and then is purified by the activated carbon and other materials in the filter cartridge. The purified gas is discharged through the exhaust pipe, reducing pollution.
[0040] The smoke extraction device also includes a support frame 6, a first adjustment component 7, a movable frame 8, and a drive mechanism 9. The connecting pipe 3 is fixed to the support frame 6, which is fixed to the ground, and provides support and fixation for the connecting pipe 3, the adjustment pipe 2 connected to the connecting pipe 3, and the suction box 1.
[0041] The first adjustment assembly 7 includes a first connector 71 and a second connector 72 rotatably connected about a centerline parallel to a first direction. The first connector 71 is connected to the connecting pipe 3, and the second connector 72 is connected to the suction box 1. A movable frame 8 is connected to the second connector 72 and is slidably connected to the support frame 6 along a second direction. The second connector 72 has a groove 721 along a third direction. The movable frame 8 is connected to a connecting rod 83, which passes through and is slidably connected to the groove 721. By providing the groove 721, the movable frame 8 slides within the groove 721 via the connecting rod 83. The drive mechanism 9 is fixed to the support frame 6, and its output end is connected to the movable frame 8. It can drive the movable frame 8 to move along the second direction. The groove 721 of the second connector 72 moves relative to the connecting rod 83 and rotates about the first connector 71. The adjustment pipe 2 undergoes adaptive deformation, that is, the movable frame 8 drives the second connector 72 to rotate relative to the first connector 71, thereby adjusting the angle of the suction box 1.
[0042] Optionally, the other end of the connecting rod 83 is connected to a limit buckle 84, which abuts against the second connecting member 72 to restrict the connecting rod 83 within the slide groove 721 and prevent the connecting rod 83 from slipping out of the slide groove 721.
[0043] Since the connecting pipe 3 is fixed by the support frame 6, the first connecting member 71 connected to the connecting pipe 3 is fixed relative to the support frame 6. The drive mechanism 9 moves along the second direction via the movable frame 8, giving the second connecting member 72 a driving force along the first direction. Since the connecting rod 83 slides in the groove 721, and the second connecting member 72 and the first connecting member 71 are rotatably connected, the second connecting member 72 can deform with it. For example, if the adjusting pipe 2 is a flexible pipe, such as a rubber tube or a corrugated pipe, it is easy to bend and deform. Therefore, the movable frame 8 can make the second connecting member 72 rotate relative to the first connecting member 71, so that the suction box 1 rotates with the second connecting member 72 relative to the first connecting member 71 and the connecting pipe 3 connected to the first connecting member 71, thereby realizing the angle adjustment of the suction box 1. The outlet 12 of the suction box 1 is connected to the adjusting pipe 2, thereby adjusting the angle of the inlet 11 of the suction box 1. According to the position of the flue gas, the drive mechanism 9 drives the movable frame 8 to move, and then cooperates with the first adjusting component 7 to adjust the angle of the inlet 11 of the suction box 1, thereby improving the efficiency of flue gas collection and improving the smoke exhaust effect. Specifically, the moving frame 8 is moved a preset distance by the driving mechanism 9, and the second connecting member 72 rotates a preset angle relative to the first connecting member 71.
[0044] Two first adjustment components 7 are provided, located on both sides of the adjustment pipe 2 along the first direction. Two first connecting parts 71 are connected to the connecting pipe 3, and two second connecting parts 72 are connected to the suction box 1. The movable frame 8 includes two opposing first moving rods 81 and a second moving rod 82 connecting one end of the two first moving rods 81. The other ends of the two first moving rods 81 are slidably connected to the grooves 721 of the second connecting parts 72 of the two first adjustment components 7 via connecting rods 83. Both first moving rods 81 are slidably connected to the support frame 6, and the output end of the drive mechanism 9 is connected to the second moving rod 82. The support frame 6 is U-shaped, including two vertical beams 61 and a horizontal beam 62 connecting the two vertical beams 61. A connecting beam 63 connects the two vertical beams 61, and the drive mechanism 9 is fixed to the connecting beam 63. The two first moving rods 81 are slidably connected to the two vertical beams 61.
[0045] The drive mechanism 9 is an electric push rod, which is fixed to the connecting beam 63 of the support frame 6. Along the second direction, the second moving rod 82 is located on the side of the support frame 6 opposite to the suction box 1. The electric push rod drives the second moving rod 82 to move, causing two first moving rods 81 to slide and connect to the two vertical beams 61, and causing the second connecting pieces 72 on the two first adjusting components 7 to rotate. By setting two first adjusting components 7 to simultaneously drive the suction box 1 to rotate, uniform force distribution is ensured, improving reliability. The electric push rod is connected to an external power source, facilitating control of the moving distance of the mobile frame 8. By setting two vertical beams 61 of the support frame 6, with the connecting pipe 3 connected to the horizontal beam 62, the structure is compact, saving installation space. The mobile frame 8, by setting two first moving rods 81, each connected to one adjusting component, allows one drive mechanism 9 to simultaneously drive both first moving rods 81 and the corresponding two first adjusting components 7 via the second moving rod 82, reducing the number of drive mechanisms 9 used, simplifying the structure, and saving costs.
[0046] The smoke exhaust device of the filter-type cigarette laboratory also includes a second adjustment component 10, which includes an adjustment plate 101. One end of the adjustment plate 101 is rotatably connected to the inside of the suction box 1, and the other end faces the inlet 11 of the suction box 1. The adjustment plate 101 rotates to adjust the size of the inlet 11 of the suction box 1. By controlling the tilt angle of the adjustment plate 101, the size of the inlet 11 of the suction box 1 can be adjusted. Specifically, rotating the adjustment plate 101 towards the middle position of the inlet 11 can reduce the size of the inlet 11, and rotating the adjustment plate 101 towards both sides of the inlet 11 can increase the size of the inlet 11, which facilitates concentrated absorption of smoke and makes it easier to adjust the smoke extraction effect of the suction box 1.
[0047] The second adjustment assembly 10 also includes a guide member 106 disposed inside the suction box 1. The guide member 106 is connected to the side wall of the suction box 1 by welding or by screws. The guide member 106 has an inclined surface that is inclined towards the side wall of the suction box 1 along the direction from the inlet 11 to the outlet 12 of the suction box 1, thereby guiding the flow of air on the inner wall of the suction box 1.
[0048] The second adjustment assembly 10 also includes a slider 102, a locking member 103, and a sliding rod 104. The slider 102 is fixed to the side wall of the suction box 1. The sliding rod 104 is slidably connected to the slider 102, with one end connected to the adjustment plate 101. The locking member 103 is connected to the slider 102, and its end can be connected to the sliding rod 104 to lock the sliding rod 104 and the slider 102 relative to each other. By moving the sliding rod 104 on the slider 102, the adjustment plate 101 is rotated, facilitating adjustment.
[0049] Two second adjustment components 10 are provided. The adjustment plates 101 of the two adjustment components are arranged opposite to each other along the second direction and are rotatably connected to the inner side of the suction box 1. The two adjustment plates 101 are adjusted simultaneously to increase the adjustment range of the opening area of the inlet 11. Guide blocks are symmetrically fixed on the inner walls of the left and right sides of the suction box 1, and the adjustment plates 101 are located below the guide blocks. The adjustment plates 101 are rotatably connected to the guide blocks through a rotating shaft.
[0050] There are two sliders 102, which are fixedly installed on the two side walls of the suction box 1 respectively. Two slide rods 104 are slidably connected to the two sliders 102. The inner end of the slide rod 104 is screwed onto the corresponding adjustment plate 101 by a hinge seat. The tilt angle of the adjustment plate 101 is controlled by the slide rod 104. The outer end of the slide rod 104 is fixed with a pull ring 107, and the pull ring 107 is provided with a protective pad 108 to facilitate the operator to push and pull the slide rod 104 to move.
[0051] The locking element 103 can specifically be a connecting screw, of which there are two, correspondingly connected to the two sliders 102, and threadedly screwed into the threaded hole 109 of the slide rod 104, facilitating the fixing of the slide rod 104 within the slider 102. Optionally, the slide rod 104 has multiple threaded holes 109, and the connecting screw can be connected to one of the threaded holes 109. In other embodiments, the end of the connecting screw abuts against the outer periphery of the slide rod 104, which can also achieve the fixing of the slide rod 104.
[0052] The second adjustment component 10 also includes a baffle 105, which is located inside the air intake box 1 and between the side wall of the air intake box 1 and the adjustment plate 101. The baffle 105 is used to block the gap between the side wall of the air intake box 1 and the adjustment plate 101 to prevent air diversion from affecting the smoke exhaust effect.
[0053] The left and right sides of the suction box 1 are rotatably connected to baffles 105 via rotating rods. The rotating rods are equipped with torsion springs, and the two ends of the torsion springs abut against the baffles 105 and the inner wall of the suction box 1, respectively, so that the baffles 105 abut against the adjusting plate 101, thereby blocking the gap between the adjusting plate 101 and the suction box 1, and avoiding affecting the effect of smoke absorption between the two adjusting plates 101.
[0054] The method of using the smoke exhaust device in the cigarette laboratory includes the following steps: According to the location of the smoke exhaust, the electric push rod is activated, the electric push rod controls the movement of the moving frame 8, the moving frame 8 drives the limit buckle 84 to move synchronously, and then the connecting rod 83 slides in the slide groove 721, thereby driving the second connecting piece 72 to rotate. The second connecting piece 72 drives the suction box 1 to rotate, and at the same time the adjusting pipe 2 bends and deforms, thereby adjusting the position of the inlet 11 of the suction box 1, so as to facilitate the intake of smoke into the filter cartridge, the filter element in the filter cartridge for purification treatment, and then the smoke is discharged from the laboratory through the centrifuge 5 and the smoke exhaust pipe.
[0055] Simultaneously, depending on the size of the exhaust smoke, the sliding rod 104 is controlled to slide within the slider 102 via the pull ring 107. The sliding rod 104 drives the adjusting plate 101 to rotate and tilt, thereby adjusting the distance between the bottom ends of the two adjusting plates 101. The position of the sliding rod 104 is fixed by the connecting screw, thereby fixing the size of the inlet 11 at the bottom of the suction box 1. The smaller the distance between the bottom ends of the two adjusting plates 101, the greater the suction force under the same power, which makes it easier to concentrate the absorption of smoke.
[0056] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
