Description

Technical Field

[0001] The present application relates to the technical field of flower fragrance extraction, and particularly relates to a jasmine fragrance adsorption device. Background Art

[0002] Currently, in the production process of jasmine tea, there is a step of extracting essential oil from the head fragrance of jasmine flowers. Specifically, before the jasmine flowers bloom, the jasmine flowers are placed in a working chamber, and the working chamber is connected to an aroma adsorption device. The aroma adsorption device includes an adsorption cylinder and a suction member. The adsorption cylinder is filled with an adsorbent material. The two ends of the adsorption cylinder are respectively communicated with an air inlet pipe and an air outlet pipe. The air inlet pipe is communicated with the working chamber, and the air outlet pipe is communicated with the suction member. The suction member is used to draw the aroma in the working chamber through the adsorption cylinder to the suction member. After the aroma passes through the adsorption cylinder, the adsorbent material adsorbs the aroma molecules, and other odorless gases are discharged into the atmosphere.

[0003] In view of the above related technologies, when the aroma passes through the adsorbent material in the adsorption cylinder, the aroma molecules adhere to the surface of the adsorbent material. During the process that the suction member draws the aroma airflow through the adsorption cylinder, due to the suction force of the suction member, most of the airflow in the adsorption cylinder will concentrate on the path opposite to the air outlet pipe. Therefore, when the surface of the adsorbent material in the part opposite to the air outlet pipe is covered with aroma molecules and it is not easy to adsorb the aroma molecules anymore, some aroma molecules will diffuse to the adsorbent material around the airflow, and the airflow will drive some aroma molecules to be directly discharged from the suction member, resulting in an increase in the loss rate of aroma molecules. Summary of the Invention

[0004] In order to reduce the loss rate of aroma molecules, the present application provides a jasmine fragrance adsorption device.

[0005] The present application provides a jasmine fragrance adsorption device, adopting the following technical solution:

[0006] A jasmine fragrance adsorption device includes an adsorption cylinder, an air inlet pipe, an air outlet pipe and a suction member. The air inlet pipe and the air outlet pipe are respectively communicated with the two opposite ends of the adsorption cylinder, and the air inlet pipe is communicated with the working chamber, and the air outlet pipe is communicated with the suction member. The adsorption cylinder is filled with an adsorbent material. The device further includes a material transfer cylinder which is rotatably connected inside the adsorption cylinder. The material transfer cylinder includes an outer cylinder, a central column and a partition plate. The two opposite ends of the outer cylinder are through. The central column is coaxially arranged with the outer cylinder. The partition plate is connected between the outer cylinder and the central column to divide the space between the outer cylinder and the partition plate to form at least two loading chambers for loading the adsorbent material. The air inlet pipe and the air outlet pipe are eccentrically arranged relative to the material transfer cylinder, and both the air inlet pipe and the air outlet pipe are communicated with the loading chambers. The adsorption cylinder is provided with a rotating assembly for driving the material transfer cylinder to rotate.

[0007] By adopting the above technical solution, the outer cylinder moves within the material transfer cylinder driven by the rotating assembly, and the air inlet pipe and the air outlet pipe are eccentrically arranged relative to the material transfer cylinder. When the air flow moves from the air inlet pipe to the air suction pipe, the outer cylinder rotates, so that all the adsorption materials in the material transfer cylinder can move onto the air flow movement path. During the continuous transportation of the air flow, the aroma molecules can be evenly distributed on the adsorption materials, thereby reducing the loss rate of the aroma molecules.

[0008] Optionally, the rotating assembly includes a support seat, a rotating ring, a magnetic member and a power source. The rotating ring is rotatably connected to the support seat and rotatably sleeved on the outer wall of the adsorption cylinder. The magnetic member is embedded in the rotating ring for magnetically attracting the material transfer cylinder, and the power source is used to drive the rotating ring to rotate.

[0009] By adopting the above technical solution, during the rotation of the rotating ring, the material transfer cylinder can move together with the rotating ring under the magnetic attraction of the magnetic member.

[0010] Optionally, the adsorption cylinder includes a main cylinder and a side plate. The side of the main cylinder has an entrance and exit for the material transfer cylinder to enter and exit. The side plate is detachably connected to the entrance and exit of the main cylinder to open and close the entrance and exit. The support seat is connected with a lifting source for driving the rotating assembly to move axially along the adsorption cylinder, so that the rotating assembly can be separated from the adsorption cylinder.

[0011] By adopting the above technical solution, the material transfer cylinder can enter or exit the adsorption cylinder through the entrance and exit, which is convenient for taking and placing the material transfer cylinder and the adsorption materials. The setting of the lifting source enables the rotating assembly to be separated from the adsorption cylinder, so that the side plate can be removed from the main cylinder.

[0012] Optionally, the material transfer cylinder further includes a closing cover for covering the opposite ends of the outer cylinder. The closing cover has a through hole for communicating with the air inlet pipe or the air outlet pipe. An opening and closing leaf for opening and closing the through hole moves within the closing cover. A plugging portion for protruding from the closing cover and being inserted and magnetically attracted to the outer cylinder also moves on the closing cover. There is a linkage assembly between the end of the main cylinder and the closing cover. When the material transfer cylinder moves into the main cylinder, the linkage assembly can drive the plugging portion to move away from the outer cylinder.

[0013] By adopting the above technical solution, when the closing cover covers the outer cylinder and the opening and closing leaf closes the through hole, the adsorption materials can be sealed in the outer cylinder without contacting the external air of the outer cylinder, so as to reduce the volatilization of the aroma molecules on the adsorption materials, which is convenient for storing the adsorption materials in the outer cylinder. When a new material transfer cylinder and adsorption materials are replaced on the adsorption cylinder and the aroma molecules need to be extracted in the next process, the adsorption materials can be taken out for operation.

[0014] Optionally, the linkage assembly includes

[0015] The central axis is coaxially arranged with the closing cover and moves inside the closing cover along the axis of the closing cover.

[0016] A first elastic member, located in the closing cover and connected to the central axis, for giving the central axis a tendency to move away from the material transfer barrel;

[0017] A telescopic rod, with two ends respectively hinged between the central axis and the plug-in portion, and a middle portion rotatably connected to the closing cover and capable of telescoping;

[0018] A pressure column, opposite to the central shaft, movably connected to the main cylinder, and used for pressing and holding the central shaft to drive the central shaft to move;

[0019] A driving member, installed on the adsorption cylinder and connected to the pressure column, for driving the pressure column to move;

[0020] The closing cover has a movable cavity for the linkage assembly to move, and the closing cover has a clearance opening for the pressure column to move into the closing cover and abut against the central axis. When the plug-in part moves to be accommodated in the closing cover, the central axis moves away from the clearance opening.

[0021] By adopting the above technical solution, through the cooperation of the pressure column and the first elastic member, and the linkage of the telescopic rod, the state of the plug-in part can be switched, so that the plug-in part is in a state of protruding or being accommodated in the closed cover.

[0022] Optionally, the telescopic rod includes a rotating rod and a moving rod, the rotating rod is rotatably connected to the closing cover, the moving rod slides relative to the rotating rod at two ends of the rotating rod along the length direction of the rotating rod, and the ends of the moving rods at the opposite ends of the rotating rod away from the rotating rod are respectively hinged to the central axis and the plug-in portion.

[0023] By adopting the above technical solution, the movable rod can move relative to the rotating rod, so that the telescopic rod can be telescoped as needed.

[0024] Optionally, a limit key is provided on the periphery of the pressure column, and the closing cover is provided with a limit opening at the clearance opening for the limit key to slide through.

[0025] By adopting the above technical solution, the cooperation between the limit key and the limit opening limits the rotation of the closing cover when the pressure column is plugged into the closing cover, so that the through hole and the air inlet pipe or the air outlet pipe are not easily misaligned.

[0026] Optionally, the closing cover has a movable groove for the opening and closing leaf to rotate around the axis of the closing cover, and the movable groove is connected to the through hole. The linkage assembly also includes a guide column arranged on the opening and closing leaf, and the central axis is provided with a guide groove for the guide column to slide, and the guide groove is inclined along the circumferential direction of the central axis, so that when the plug-in portion protrudes from the closing cover, the central axis guides the opening and closing leaf to close the through hole, and when the plug-in portion is received in the closing cover, the central axis guides the opening and closing leaf to open the through hole.

[0027] By adopting the above technical solution, the guide column moves obliquely along the circumferential direction of the central axis in the guide groove, so that when the central axis moves axially along the closing cover, the opening and closing leaf is driven to move axially along the opening and closing cover in the moving groove to open or close the through hole.

[0028] Optionally, an extension tube is movable at one end of the air inlet pipe and the air outlet pipe close to the adsorption cylinder, and a second elastic member is provided between the extension tube and the opposite air inlet pipe and air outlet pipe. The second elastic member is used to drive the extension tube to be inserted into the through hole and is located on the side of the opening and closing leaf away from the material transferring cylinder, and the outer peripheral wall of the extension tube has a guide slope.

[0029] By adopting the above technical solution, the closing cover enters the adsorption cylinder and can first press the extension tube into the air inlet pipe or the air outlet pipe through the guiding slope. When the through hole is opposite to the extension tube, the extension tube is extended into the through hole by the action of the second elastic member to limit the position of the closing cover.

[0030] Optionally, a surface of the closing cover close to the material transfer cylinder has a filter screen at the through hole to limit the adsorbent from moving into the through hole.

[0031] By adopting the above technical solution, the filter screen can prevent the adsorbent in the outer cylinder from falling into the through hole.

[0032] In summary, this application has the following beneficial effects:

[0033] By rotating the material transfer cylinder in the adsorption cylinder, the adsorption material can be driven to move in the adsorption cylinder, so that the adsorption material in each place can pass through the path of the airflow, thereby improving the adsorption efficiency of the adsorption material on the aroma molecules in the airflow and reducing the loss rate of the aroma molecules.

[0045] The following is combined with Figure 1-10 This application is described in further detail.

[0046] The present application embodiment discloses a jasmine fragrance adsorption device. Figure 1, the jasmine fragrance adsorption device includes an adsorption cylinder 1, an air inlet pipe 2, an air outlet pipe 3, and a suction member 4. The adsorption cylinder 1 is in the shape of a cylinder with its axis extending in the vertical direction. The air inlet pipe 2 is in the shape of a circular tube and is fixedly connected to the top end of the adsorption cylinder 1. The air outlet pipe 3 is in the shape of a circular tube and is fixedly connected to the bottom end of the adsorption cylinder 1, and the diameters of the air inlet pipe 2 and the air outlet pipe 3 are the same. One end of the air inlet pipe 2 away from the adsorption cylinder 1 is fixedly connected to the working chamber 5, and one end of the air outlet pipe 3 away from the adsorption cylinder 1 is fixedly connected to the suction member 4. In this embodiment, the suction member 4 is a vacuum pump, and the vacuum pump passes the fragrance of jasmine in the working chamber 5 through the air inlet pipe 2, the adsorption cylinder 1, and the air outlet pipe 3 in sequence, and then discharges it from the vacuum pump.

[0047] Referring to Figure 2 , the adsorption device further includes a material transfer cylinder 6, and the material transfer cylinder 6 includes an outer cylinder 61, a central column 62, and a partition piece 63. The outer cylinder 61 is in the shape of a cylinder with both ends penetrating. The central column 62 is in the shape of a cylinder coaxial with the outer cylinder 61, and the central column 62 is located in the inner cavity of the outer cylinder 61. The partition piece 63 is in the shape of a mesh, and there are at least two partition pieces 63. All the partition pieces 63 are fixedly arranged at equal intervals along the circumferential direction of the central column 62 between the central column 62 and the outer cylinder 61 to divide the inner cavity of the outer cylinder 61 into multiple loading cavities 7. In this embodiment, there are four partition pieces 63.

[0048] Each loading cavity 7 is filled with an adsorption material. The adsorption material in this embodiment is activated carbon, and the particle size of the adsorption material is larger than the pore diameter of the partition piece 63, so that the air between the loading cavities 7 is interconnected, but the adsorption material in the loading cavity 7 is not easily displaced to another loading cavity 7.

[0049] Referring to Figure 1 and Figure 2 , the outer diameter of the outer cylinder 61 is the same as the inner diameter of the adsorption cylinder 1, and the outer cylinder 61 rotates coaxially inside the adsorption cylinder 1. The extension lines of the axes of the air inlet pipe 2 and the air outlet pipe 3 coincide, and the axes of the air inlet pipe 2 and the air outlet pipe 3 are parallel to the central column 62. Both the air inlet pipe 2 and the air outlet pipe 3 are communicated with the loading cavity 7, so that the air inlet pipe 2 and the air outlet pipe 3 are eccentrically arranged relative to the outer cylinder 61. When the outer cylinder 61 rotates around its own axis inside the adsorption cylinder 1, the adsorption material is driven to move relative to the adsorption cylinder 1 through the division of the loading cavity 7, so that during the process of continuously inputting the fragrance from the air inlet pipe 2 to the air outlet pipe 3, the fragrance can pass through different adsorption materials to improve the uniformity of the adsorption material attached with fragrance molecules.

[0050] Referring to Figure 2 and Figure 3 , and in order to drive the material transfer cylinder 6 to rotate, the adsorption cylinder 1 is provided with a rotating assembly 8. Specifically, the rotating assembly 8 includes a support seat 81, a rotating ring 82, a magnetic member 83, and a power source 84. Combining Figure 1, the support base 81 is used to support the rotating ring 82. The rotating ring 82 is in the shape of a circular ring with an inner diameter consistent with the outer diameter of the adsorption cylinder 1. The rotating ring 82 is rotatably connected to the support base 81 and coaxially sleeved on the outer wall of the adsorption cylinder 1. The magnetic member 83 is a magnet embedded in the inner wall of the rotating ring 82, and a plurality of magnets are embedded along the circumferential direction of the rotating ring 82. The power source 84 is installed on the support base 81 and is used to provide power for the rotation of the rotating ring 82.

[0051] Refer to Figure 2 and Figure 3 , the adsorption cylinder 1 is made of a material such as plastic that does not adsorb to magnets and does not isolate the magnetic field, and the outer side wall of the outer cylinder 61 is made of a metal or alloy material that can be attracted to the magnet. Therefore, when the rotating ring 82 rotates under the drive of the power source 84, the outer cylinder 61 rotates together with the rotating ring 82 due to the attraction of the magnet.

[0052] Refer to Figure 3 , specifically, the power source 84 includes a toothed ring 841, a gear 842, and a motor 843. The toothed ring 841 is coaxially sleeved on the outer wall of the rotating ring 82 and fixed to the rotating ring 82. Teeth are evenly spaced on the outer circumference of the toothed ring 841. The gear 842 is rotatably connected to the support base 81 and meshes with the toothed ring 841. The motor 843 is installed on the support base 81, and the output end of the motor 843 is fixed to the gear 842, so that the motor 843 can drive the gear 842 to rotate. Thus, when the gear 842 rotates, it drives the gear 842 and the rotating ring 82 to rotate together.

[0053] Refer to Figure 2 and Figure 4 , in order to facilitate the removal of the material transfer cylinder 6 from the adsorption cylinder 1 to take out the adsorbed material and collect the adsorption cylinder 1, the adsorption cylinder 1 includes a main cylinder 101 and a side plate 102. The main cylinder 101 is in the shape of a cylinder with an inlet / outlet 9. The inside of the main cylinder 101 is hollow, and both the upper and lower ends of the main cylinder 101 are closed and not penetrated. The inlet / outlet 9 is opened on the side of the main cylinder 101, and the air inlet pipe 2 and the air outlet pipe 3 are respectively fixed to the opposite ends of the main cylinder 101.

[0054] The extension dimension of the inlet / outlet 9 along the circumferential direction of the main cylinder 101 is greater than or equal to half of the main cylinder 101, and the extension dimension of the inlet / outlet 9 along the axial direction of the main cylinder 101 is equal to the distance between the inner walls of the upper and lower ends of the main cylinder 101. The side plate 102 is in the shape of an arc plate adapted to the size of the inlet / outlet 9. The side plate 102 is detachably connected to the inlet / outlet 9 of the main cylinder 101 through bolts, so that when the main cylinder 101 and the side plate 102 are assembled, they can form a cylindrical shape with a closed inner cavity. And when the side plate 102 is removed from the main board, the material transfer cylinder 6 can enter the main cylinder 101 through the inlet / outlet 9 for placement.

[0055] Refer to Figure 3 and Figure 4, the bottom of the support base 81 is connected to the lifting source 10. The lifting source 10 is a first cylinder with the axis of the piston rod extending in the vertical direction. The first cylinder is connected to the outer wall of the adsorption cylinder 1, and the piston rod of the first cylinder is connected to the support base 81 to drive the support base 81 to move up and down, thereby driving the rotating assembly 8 to move up and down. When the piston rod of the first cylinder extends, the rotating ring 82 is sleeved on the outer wall of the adsorption cylinder 1 and located in the middle of the adsorption cylinder 1. When the piston rod of the first cylinder retracts, it drives the rotating assembly 8 to move downward and separate from the adsorption cylinder 1, so that the rotating ring 82 separates from the adsorption cylinder 1. At this time, the side plate 102 can be detached from the main cylinder 101.

[0056] Refer to Figure 2 and Figure 5 , further, in order to prevent the adsorbed material from falling out when the transfer cylinder 6 is taken out, the transfer cylinder 6 further includes two closing covers 64. The two closing covers 64 have the same structure and are both disc-shaped. The outer diameter of the closing cover 64 is the same as the outer diameter of the outer cylinder 61, and the two closing covers 64 respectively cover the openings at the opposite ends of the outer cylinder 61.

[0057] Refer to Figure 2 and Figure 6 , specifically, a plugging portion 13 moves along a direction parallel to its own axis on the closing cover 64. The plugging portion 13 is square-shaped, and a magnet is embedded in the plugging portion 13. One surface of the closing cover 64 has a first sliding groove 29 for the plugging portion 13 to move out of the surface of the closing cover 64. The opposite end faces of the outer cylinder 61 have plugging grooves 30 for the plugging portion 13 to be plugged. Magnets attracted to the magnets on the plugging portion 13 are embedded in the plugging grooves 30. When the plugging portion 13 protrudes from the surface of the closing cover 64, the plugging portion 13 can be plugged into the plugging groove 30 and magnetically attracted to the outer cylinder 61, so that the closing cover 64 abuts against the surface of the outer cylinder 61 coaxially to close the outer cylinder 61.

[0058] Refer to Figure 4 and Figure 5 , in addition, through holes 11 penetrating through the opposite two surfaces of the two closing covers 64 are provided. The through holes 11 are used to communicate with the air inlet pipe 2 or the air outlet pipe 3 so that air flow can be transmitted through the closing covers 64.

[0059] Refer to Figure 4 and Figure 7 , and an opening and closing leaf 12 rotates along its own axis inside the closing cover 64. A moving groove 22 for the opening and closing leaf 12 to move is provided inside the closing cover 64. The moving groove 22 is communicated with the through hole 11. When the opening and closing leaf 12 moves in the moving groove 22 to be opposite to the through hole 11, the opening and closing leaf 12 closes the through hole 11 to enclose the adsorbed material in the transfer cylinder 6. The upper and lower ends of the main cylinder 101 respectively correspond to the two closing covers 64 one by one, and there is a linkage assembly between the end of the main cylinder 101 and the corresponding closing cover 64. Combine Figure 2, the linkage component is used to drive the insertion part 13 and the opening and closing blade 12 to move, so that when the material transfer cylinder 6 moves into the main cylinder 101, the linkage component can separate the insertion part 13 from the outer cylinder 61, and at the same time, the closing cover 64 moves to open the through hole 11, or make the insertion part 13 inserted into the outer cylinder 61, and at the same time, the closing cover 64 moves to close the through hole 11.

[0060] Refer to Figure 6 and Figure 8 , first of all, the linkage component includes a central shaft 14, a first elastic member 15, a telescopic rod 16, a pressing column 17 and a driving member 18. First of all, the central shaft 14 is cylindrical, coaxially arranged with the closing cover 64, and the central shaft 14 moves in the closing cover 64 along the axis direction of the closing cover 64. A second chute 31 for the closing cover 64 to slide is provided on the closing cover 64.

[0061] There are two telescopic rods 16 in each closing cover 64. The two telescopic rods 16 respectively correspond to the two insertion parts 13 one by one. One end of the telescopic rod 16 is hinged to the outer wall of the corresponding insertion part 13, and the other end of the telescopic rod 16 is hinged to the outer wall of the central shaft 14. And the two telescopic rods 16 are respectively located on the opposite sides of the central shaft 14, and the telescopic rod 16 can be telescoped. The closing cover 64 is provided with a moving cavity 32 for the telescopic rod 16 to rotate and telescope between the first chute 29 and the second chute 31. The moving cavity 32 communicates with the first chute 29 and the second chute 31 at the same time, and the first chute 29, the second chute 31 and the moving cavity 32 together form a moving cavity for the linkage component to move. When the central shaft 14 moves through the telescopic rod 16, it drives the insertion part 13 to move in the opposite direction.

[0062] Refer to Figure 6 and Figure 8 , an installation frame is fixed on the outside of the end of the main cylinder 101. The driving member 18 is a second cylinder. The second cylinder is mounted on the installation frame, and the pressing column 17 is fixed on the piston rod of the second cylinder. The pressing column 17 is coaxial with the main cylinder 101. One end of the pressing column 17 away from the main cylinder 101 has a sealing disc 33, and the sealing disc 33 is made of rubber. A through hole for the pressing column 17 to pass through into the main cylinder 101 is provided at the end of the main cylinder 101. A relief opening 19 for the pressing column 17 to move into the closing cover 64 is provided on the surface of the closing cover 64 facing away from the first chute 29. The size of the relief opening 19 is smaller than the size of the pressing column 17, and the central shaft 14 cannot move out of the closing cover 64 through the relief opening 19. And the relief opening 19 communicates with the second chute 31, so that the pressing column 17 can enter the second chute 31 through the relief opening 19 and abut against the central shaft 14 to drive the central shaft 14 to move towards the outer cylinder 61. And when the piston rod of the second cylinder is fully extended, the central shaft 14 is pressed by the pressing column 17 to drive the insertion part 13 to be completely received in the first chute 29, and the sealing disc 33 abuts against the outer end wall of the main cylinder 101, so that only the air inlet pipe 2 and the air outlet pipe 3 are communicated with the inside of the main cylinder 101.

[0063] The first elastic member 15 is a first spring, which is located in the second chute 31. One end of the first spring is connected to the inner wall of the second chute 31 away from the clearance opening 19, and the other end of the first spring is connected to the central shaft 14. The elastic force of the first spring is used to give the central shaft 14 a tendency to move toward the clearance opening 19. When the pressure column 17 moves out of the closing cover 64 and separates from the central shaft 14, the first spring drives the central shaft 14 to move, so that the central shaft 14 abuts against the inner wall of the second chute 31 at one end close to the clearance opening 19. At this time, the telescopic rod 16 drives the plug-in portion 13 to move to the surface of the protruding closing cover 64.

[0064] Reference Figure 7 and Figure 9 , Secondly, the linkage assembly also includes a guide column 23, the opening and closing leaf 12 is fan-shaped, the guide column 23 is fixed on the opening and closing leaf 12, and a guide groove 24 for the guide column 23 to slide is provided on the outer wall of the central shaft 14, and the guide groove 24 is inclined along the circumferential direction of the central shaft 14. The opening and closing leaf 12 can only move along the horizontal plane under the limiting action of the moving groove 22, so that when the central shaft 14 slides axially along the closing cover 64, the guide column 23 is driven to move in the guide groove 24, so that the guide column 23 moves circumferentially along the central shaft 14, so as to drive the opening and closing leaf 12 to rotate in the closing cover 64.

[0065] Reference Figure 7 and Figure 6 Therefore, before the transfer cylinder 6 is placed into the main cylinder 101, the central shaft 14 is acted upon by the elastic force of the first spring, driving the plug-in portion 13 to move out of the closing cover 64 and plug-fit with the outer cylinder 61, thereby Figure 6 and Figure 9 At this time, the guide column 23 is located at one end of the guide groove 24, and the opening and closing leaf 12 closes the through hole 11.

[0066] Reference Figure 4 and Figure 6 When the transfer barrel 6 is placed in the main barrel 101, the through hole 11 is opposite to the air inlet pipe 2 or the air outlet pipe 3. When the outer barrel 61 is located in the main barrel 101 and needs to be rotated, the pressure column 17 is used to press the central shaft 14 until the plug-in portion 13 is completely received in the closing cover 64. The central shaft 14 drives the guide column 23 to move to the other end of the guide groove 24. At this time, the opening and closing leaf 12 moves to open the through hole 11, so that the airflow can enter and exit the transfer barrel 6 through the through hole 11. Figure 6 and Figure 9 When the transfer cylinder 6 needs to be taken out, the pressure column 17 is separated from the closing cover 64, so that the outer cylinder 61 continues to rotate until the insertion groove 30 is opposite to the first sliding groove 29, and the insertion part 13 can be moved out of the closing cover 64 and inserted into the outer cylinder 61 under the drive of the first spring.

[0067] Reference Figure 6The telescopic rod 16 includes a rotating rod 161 and a moving rod 162. The middle part of the rotating rod 161 is rotatably connected to the active cavity through a rotating shaft. Each telescopic rod 16 has two moving rods 162. The length extension direction of the moving rod 162 is consistent with that of the rotating rod 161. The two moving rods 162 slide along the length direction of the rotating rod 161 at the opposite ends of the rotating rod 161, and the ends of the two moving rods 162 that are away from each other are hinged to the central axis 14 and the plug-in portion 13 respectively.

[0068] Reference Figure 6 and Figure 8 Furthermore, in order to prevent the outer cylinder 61 from driving the closing cover 64 to rotate together when rotating, so that the through hole 11 and the air inlet pipe 2 or the air outlet pipe 3 are not easily misaligned, the pressure column 17 has a plurality of limit keys 20 arranged at even intervals on the side, and the closing cover 64 has limit openings 21 corresponding to the limit keys 20 on the side of the yield opening 19. When the pressure column 17 presses the central axis 14, the limit keys 20 are plugged into and matched with the limit openings 21 to limit the rotation of the closing cover 64.

[0069] Reference Figure 4 and Figure 10 Furthermore, the ends of the air inlet pipe 2 and the air outlet pipe 3 connected to the adsorption cylinder 1 are both provided with an extension pipe 25. Taking the air inlet pipe 2 as an example, the extension pipe 25 coaxially slides on the end of the air inlet pipe 2, and the inner diameter of the extension pipe 25 is larger than the inner diameter of the air inlet pipe 2, and the outer diameter of the extension pipe 25 is smaller than the outer diameter of the air inlet pipe 2. A groove for the extension pipe 25 to slide is provided at the end of the air inlet pipe 2. The air inlet pipe 2 is connected with a second elastic member 26 in the groove, and the second elastic member 26 is a second spring, which is connected to the extension pipe 25 to drive the extension pipe 25 to enter the interior of the main cylinder 101. The outer peripheral side of the extension pipe 25 has a guide slope 27 along its own axial direction, so that the wall thickness of the extension pipe 25 gradually decreases in the direction away from the air inlet pipe 2.

[0070] Reference Figure 2 and Figure 10 When the outer cylinder 61 and the closing cover 64 move into the main cylinder 101, the closing cover 64 presses the extension tube 25 into the air inlet pipe 2 or the air outlet pipe 3 through the guiding slope 27. When the through hole 11 on the closing cover 64 is opposite to the air inlet pipe 2 or the air outlet pipe 3, the extension tube 25 is driven by the second spring to extend into the through hole 11, and the extension tube 25 is located on the side of the opening and closing leaf 12 away from the outer cylinder 61, so that the closing cover 64 can quickly cooperate with the air inlet pipe 2 and the air outlet pipe 3.

[0071] Reference Figure 2 and Figure 5 In addition, in order to prevent the adsorbent in the outer cylinder 61 from falling into the through hole 11 when the through hole 11 is opened, a filter screen 28 is fixed at the through hole 11 on one side of the closing cover 64 close to the outer cylinder 61. The mesh of the filter screen 28 is smaller than the pore size of the adsorbent to limit the adsorbent from falling into the through hole 11.

[0072] The implementation principle of a jasmine aroma adsorption device in an embodiment of this application is as follows: First, load activated carbon into the loading chamber 7, and close the loading chamber 7 by connecting it with the outer cylinder 61 through the closing cover 64. Then, place the transfer cylinder 6 into the adsorption cylinder 1. Next, drive the pressing column 17 to press down on the central shaft 14 through the second cylinder, so that the central shaft 14 drives the insertion part 13 to be received into the closing cover 64 to disengage from the outer cylinder 61. After that, the first cylinder drives the support seat 81 to move upward, so that the rotating ring 82 sleeves the main cylinder 101. The power source 84 drives the rotating ring 82 to rotate, and the outer cylinder 61 rotates together with the rotating ring 82 due to the magnetic attraction with the rotating ring 82. The vacuum pump is started to allow the aroma in the working chamber 5 to enter the adsorption cylinder 1 through the air inlet pipe 2. After the aroma molecules in the aroma are adsorbed on the activated carbon, the aroma molecules are discharged from the vacuum pump through the air outlet pipe 3.

[0073] The above are all the preferred embodiments of this application. It does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
