Description

Technical Field

[0001] This invention relates to an apparatus and method for extracting the natural aromas of tea and herbs, belonging to the field of tea extraction technology. Background Technology

[0002] In the field of natural plant aroma extraction, the aroma extraction of tea and herbal materials has always attracted much attention. Traditional extraction processes mostly use water extraction or organic solvent extraction, which dissolve and release the aroma components by penetrating the plant cell structure through solvents.

[0003] Traditional extraction equipment often uses a fixed tank structure. After extraction, the tea residue and herbal materials need to be removed from the extraction tank manually or by hoisting equipment. The extraction tank usually needs to be opened manually and the residue poured out. The operation is time-consuming and labor-intensive. In addition, the temperature of the tea residue and herbal materials after extraction is generally high. Manually pouring out the residue can easily cause burns and pose a safety hazard.

[0004] Therefore, a new solution is needed to address this problem. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a device and method for extracting the natural aroma of tea and herbs. It solves the problems in the prior art where tea residue and herbal materials usually require manual opening of the extraction tank and dumping of residue, which is time-consuming and laborious. In addition, the temperature of tea residue and herbal materials after extraction is generally high, and manual dumping of residue can easily cause burns, posing a safety hazard.

[0006] The technical problem to be solved by the present invention is achieved by the following technical solution: a natural aroma extraction device for tea and herbs, comprising a tank body, a tank bottom, a bottom support, a pouring box on one side of the bottom support, a bottom plate fixedly connected to the side of the bottom support away from the tank body, a tray inside the tank bottom, a filter cylinder slidably connected to the tray, multiple support rods fixedly connected to the tray, the end of the support rod away from the tray being fixedly connected to the inner wall of the tank bottom, tea and herbal materials placed inside the filter cylinder, a pouring mechanism provided on the tank bottom, the pouring mechanism can pour the tea and herbal materials in the filter cylinder into the pouring box, an installation mechanism provided on the tray, the installation mechanism is used to install the filter cylinder on the tray, a connecting plate fixedly connected inside the tank, and a vibration mechanism for accelerating extraction provided on the connecting plate.

[0007] A sealing groove is provided on the side of the tank body near the bottom, and a sealing ring that can be inserted into the sealing groove is fixedly connected to the side of the tank bottom near the tank body. The material pouring mechanism includes a cylinder fixedly connected to the bottom support. The output end of the cylinder passes through the bottom support and is fixedly mounted with a fixing block. A fixing ring is fixedly connected to the bottom of the tank. A support shaft is rotatably connected to the fixing block via a bearing. One end of the support shaft is fixedly connected to the fixing ring, and the other end of the support shaft is fixedly connected to a fixing plate. A rotating rod is fixedly connected to the end of the fixing plate away from the support shaft. A roller is rotatably connected to the end of the rotating rod away from the bottom of the tank. A vertical guide groove is provided through the bottom support, and a rotating groove communicating with the vertical guide groove is also provided through the bottom support. The roller is inserted into the vertical guide groove or the rotating groove.

[0008] By adopting the above technical solution, tea and herbal materials are placed inside the filter cylinder. Then, the cylinder is activated to move the fixed block upward, thereby moving the bottom of the tank and the filter cylinder upward. During this process, the filter cylinder is moved into the tank body and the tank body comes into contact with the bottom of the tank. At this time, the sealing ring is inserted into the sealing groove to seal between the tank body and the bottom of the tank. Then, solvent (usually water or ethanol) is injected into the tank body and the bottom of the tank through the liquid inlet pipe, so that the solvent covers the tea and herbal materials inside the filter cylinder. The solvent is used to extract the tea and herbal materials, and the aroma from the tea and herbal materials is extracted to obtain the extract. When removing the extracted tea residue and herbal materials, first drain the extract from the bottom and inside of the tank. Then, activate the cylinder, causing the fixed block to move downwards. During this downward movement, the bottom of the tank and the support shaft move downwards simultaneously. The downward movement of the bottom of the tank moves the filter cylinder out of the tank, while the downward movement of the support shaft causes the rollers to slide within the vertical guide groove. Because the vertical guide groove is vertically oriented, the rollers do not cause the support shaft to rotate axially during their movement. When the support shaft moves the rollers downwards into the rotating groove, the rollers slide within the rotating groove simultaneously... The step drives the fixed plate, rotating rod, and support shaft to rotate axially around the support shaft. During the axial rotation of the support shaft, the bottom of the tank rotates simultaneously, which in turn causes the filter cylinder, which has been displaced from the tank, to rotate axially around the support shaft. This process causes the filter cylinder to flip, thereby pouring the extracted tea and herbal materials into the pouring box for collection. This eliminates the need for manual pouring using a crane or other auxiliary equipment, making it more convenient, labor-saving, efficient, and flexible. This improves extraction efficiency, avoids burns, and enhances safety and reliability, thus increasing the practicality of the extraction device.

[0009] The present invention is further configured such that: the mounting mechanism includes a first positioning ring fixedly connected to the filter cylinder; a first through groove is formed through the tray; a limiting groove is formed through the tray; a limiting block that can be inserted into the limiting groove is fixedly connected to the side of the first positioning ring near the tray; a positioning hole is formed through the limiting block; a second positioning ring is slidably connected inside the tray; one end of the second positioning ring passes through the limiting groove and can be inserted into the positioning hole; the other end of the second positioning ring passes through the first through groove and is fixedly connected to a positioning plate; a tension spring is fixedly connected between the positioning plate and the inner wall of the first through groove.

[0010] By adopting the above technical solution, in the initial state, the second positioning ring, inserted into the positioning hole, fixes the limiting block, preventing it from being pulled out of the limiting groove. This, in turn, fixes the filter cartridge, preventing it from being pulled out of the tray, thus creating a fixed connection between the tray and the filter cartridge. During disassembly, pushing the positioning plate stretches the tension spring, causing it to deform. During this process, the positioning plate rotates axially around the tray, simultaneously moving the second positioning ring away from the limiting block and sliding it out of the positioning hole. This releases the connection between the tray and the filter cartridge, completing the disassembly of the filter cartridge. This facilitates cleaning and maintenance of the filter cartridge, thereby improving the practicality of the extraction device.

[0011] The invention is further configured such that: the oscillation mechanism includes a support tube and a connecting tube fixedly connected to a connecting plate; an air box is fixedly connected to the connecting plate; a first fixing rod is inserted into the connecting tube; a second fixing rod is inserted into the support tube; a first oscillation block is fixedly connected to the end of the first fixing rod away from the connecting tube; and a second oscillation block is fixedly connected to the end of the second fixing rod away from the support tube. An air inlet pipe communicating with the air box is fixedly connected to one side of the air box; a slider is provided inside the air box; a crossbar inserted into the air inlet pipe is fixedly connected to the end of the slider near the air inlet pipe; a first sealing plug slidably connected to the air box is fixedly connected to the slider; a second air inlet and a first air inlet are provided through the air box; the end of the connecting tube is fixedly connected to the second air inlet; and the end of the support tube is fixedly connected to the first air inlet.

[0012] By adopting the above technical solution, the first sealing plug is used to increase the sealing performance of the slider in the air box. In the initial state, the slider is located between the second air inlet and the first air inlet. When the bottom of the tank abuts against the tank body, both the first and second oscillating blocks are located inside the filter cartridge and are submerged in the solution. When the air pump is started to inject air into the air inlet pipe, the slider moves towards the first air inlet. A negative pressure is formed in the space of the slider in the air box near the third air inlet, causing the first fixed rod to move upward, which in turn drives the first oscillating block to move upward. Simultaneously, the space of the slider in the air box near the first air inlet is compressed, which pushes the second fixed rod downward, which in turn drives the second oscillating block to move downward. Conversely, when the air pump draws air into the inlet pipe, it drives the first oscillating block to move downwards while simultaneously driving the second oscillating block to move upwards. During the up-and-down movement of the first and second oscillating blocks, the solution inside the tank and at the bottom of the tank is agitated, causing the solution to flow up and down. This allows the solution inside the filter cartridge to convect with the solution outside the filter cartridge, and also causes the tea and herbal materials to tumble with the solution, thereby accelerating the extraction of the tea and herbal materials and improving the quality and efficiency of the extraction. Furthermore, the opposite movement of the first and second oscillating blocks can increase the convection of the solution, thereby improving the extraction efficiency of the solution for the tea and herbal materials. Furthermore, the first and second ellipsoidal oscillating blocks move up and down, causing the solution inside the tank and at the bottom to oscillate. This method is gentler than the traditional method of using a stirring rod to accelerate the extraction of tea and herbal materials, avoiding damage to the tea and herbal materials caused by vigorous stirring. This results in a clearer extract and improves the extraction effect of the aroma of tea and herbs.

[0013] The invention is further configured as follows: a second rotating block is fixedly connected to the end of the connecting plate away from the gas box; a vertical rod is rotatably connected to the second rotating block; multiple rocking blocks are fixedly connected to the vertical rod; a sliding cylinder is slidably connected to the vertical rod; a first rotating block is fixedly connected to the sliding cylinder; a gas cylinder is fixedly connected inside the tank; a push rod is inserted into the gas cylinder; the end of the push rod away from the gas cylinder is rotatably connected to the first rotating block; a third air inlet is provided through the gas box; a positioning tube is fixedly connected to the third air inlet; and a fixed tube communicating with the positioning tube is fixedly connected to the gas cylinder. Second sealing plugs are fixedly connected to the push rod, the first fixed rod, and the second fixed rod; a second sealing plug is also fixedly installed at the end of the crossbar away from the slider.

[0014] By adopting the above technical solution, when the air pump is started and the slider moves left and right, the push rod is simultaneously driven to slide inside the air cylinder. Because the end of the push rod is rotatably connected to the first rotating block, the push rod pushes the sliding cylinder to slide on the vertical rod during the sliding process inside the air cylinder, and drives the vertical rod to rotate around the second rotating block. Then, during the reciprocating movement of the push rod inside the air cylinder, the vertical rod swings around the second rotating block, which in turn drives the rocking block to swing in the solution. The swing amplitude of the rocking block in the solution will not touch the filter cylinder, and the swing of the vertical rod and the rocking block can increase the convection of the solution in the tank and the filter cylinder, thereby making the extract more uniform. On the one hand, it improves the extraction efficiency, and on the other hand, it improves the extraction effect of tea and herbal aroma.

[0015] The invention is further configured such that: a filter plate is fixedly connected inside the bottom of the tank, the filter plate is located on the lower side of the tray, and a liquid outlet pipe communicating with the bottom of the tank is fixedly connected to the side of the bottom of the tank away from the tank body.

[0016] By adopting the above technical solution, the extract is discharged through the outlet pipe. The filter plate is used to further filter the extracted liquid, thereby preventing impurities from being mixed in with the extracted material and improving the extraction effect.

[0017] A method of using a natural aroma extraction device for tea and herbs, the method of use including: S1: Wash the tea leaves and herbs thoroughly and let them air dry. S2: Knead the tea leaves; S3: Place the tea leaves and herbal materials into the filter cylinder, start the tilting mechanism to move the bottom of the can and the filter cylinder upwards. The filter cylinder moves upwards into the can body, and the bottom of the can moves upwards to abut against the can body, thus achieving a lid seal between the can and the bottom of the can. S4: Inject the solution into the tank and the bottom of the tank through the inlet pipe, so that the solution level covers the tea leaves and herbal materials; S5: Extract the aroma from tea leaves and herbs into a solution to obtain an extract. Start the oscillation mechanism, which can make the tea leaves and herbs oscillate with the solution, thus accelerating the aroma extraction efficiency of tea leaves and herbs. S5: Discharge the extract, then start the tilting mechanism to move the bottom of the tank downwards, simultaneously moving the filter cylinder out of the tank. As the tilting mechanism continues to move the bottom of the tank downwards, it also causes the bottom of the tank to flip over, so that the extracted tea leaves and herbal materials in the filter cylinder are poured into the pouring box.

[0018] The beneficial effects of this invention are as follows: When the extracted tea residue and herbal materials are removed, the extract liquid in the bottom and inside of the tank is first discharged. Then, the cylinder is activated, causing the cylinder to move the fixed block downwards. During the downward movement of the fixed block, the bottom of the tank and the support shaft are simultaneously moved downwards. The downward movement of the bottom of the tank simultaneously moves the filter cylinder out of the tank. During the downward movement of the support shaft, the roller slides in the vertical guide groove. Because the vertical guide groove is vertically set, the roller does not cause the support shaft to rotate axially during the sliding process in the vertical guide groove. When the support shaft drives the roller to slide downwards into the rotating groove, the roller rotates. The sliding mechanism inside the tank synchronously drives the fixed plate, rotating rod, and support shaft to rotate axially around the support shaft. During the axial rotation of the support shaft, the bottom of the tank rotates synchronously, which in turn causes the filter cylinder, which has been displaced out of the tank, to rotate axially around the support shaft. This process causes the filter cylinder to flip, thereby pouring the extracted tea and herbal materials into the pouring box for collection. This eliminates the need for manual pouring using a crane or other auxiliary equipment, making it more convenient, labor-saving, efficient, and flexible. This improves extraction efficiency, avoids burns, and enhances safety and reliability, thus increasing the practicality of the extraction device. Attached Figure Description

[0021] To facilitate a clear understanding of the technical means, inventive features, objectives, and effects of this invention, the following detailed description is provided. Figures 1 to 8 The invention will be further illustrated as shown.

[0022] like Figures 1 to 6 As shown, this invention is a natural aroma extraction device for tea and herbs, comprising a tank body 1, a tank bottom 6 disposed on the tank body 1, the tank bottom 6 being located on the lower side of the tank body 1 and communicating with the interior of the tank body 1 and the tank bottom 6, a bottom support 2 disposed on the tank body 1, a pouring box 16 disposed on one side of the bottom support 2, a support plate 15 fixedly connected to the bottom support 2, the support plate 15 being fixedly installed on the tank body 1 by bolts, a bottom plate 3 fixedly connected to the side of the bottom support 2 away from the tank body 1, the bottom plate 3 having bolt holes extending through it, a tray 18 disposed inside the tank bottom 6, and a filter cylinder 17 slidably connected to the tray 18. Multiple support rods 21 are fixedly connected to the tray 18. The end of the support rod 21 away from the tray 18 is fixedly connected to the inner wall of the tank bottom 6. A liquid inlet pipe 28 communicating with the tank body 1 is fixedly connected to the tank body 1. Tea and herbal materials are placed inside the filter cylinder 17. A pouring mechanism is provided on the tank bottom 6. The pouring mechanism can pour the tea and herbal materials in the filter cylinder 17 into the pouring box 16. An installation mechanism is provided on the tray 18. The installation mechanism is used to install the filter cylinder 17 on the tray 18. A connecting plate 31 is fixedly connected inside the tank body 1. A oscillation mechanism for accelerating extraction is provided on the connecting plate 31.

[0023] like Figures 1 to 6As shown, a sealing groove 55 is provided on the side of the tank body 1 near the bottom 6. A sealing ring 54 that can be inserted into the sealing groove 55 is fixedly connected to the side of the bottom 6 near the tank body 1. A sealing element is provided in the sealing groove 55.

[0024] like Figures 1 to 5 As shown, the material pouring mechanism includes a cylinder 4 fixedly connected to the bottom support 2. The output end of the cylinder 4 passes through the bottom support 2 and is fixedly mounted with a fixing block 5. A fixing ring 8 is fixedly connected to the bottom of the tank 6. A support shaft 9 is rotatably connected to the fixing block 5 via a bearing. One end of the support shaft 9 is fixedly connected to the fixing ring 8, and the other end of the support shaft 9 is fixedly connected to a fixing plate 14. A rotating rod 13 is fixedly connected to the end of the fixing plate 14 away from the support shaft 9. A roller 12 is rotatably connected to the end of the rotating rod 13 away from the bottom of the tank 6. A vertical guide groove 10 is opened through the bottom support 2, and a rotating groove 11 communicating with the vertical guide groove 10 is opened through the bottom support 2. The roller 12 is inserted into the vertical guide groove 10 or the rotating groove 11, and the roller 12 is slidably connected to the vertical guide groove 10 or the rotating groove 11.

[0025] Tea and herbal materials are placed inside the filter cylinder 17. Then, the cylinder 4 is activated to move the fixed block 5 upward, thereby moving the bottom of the tank 6 and the filter cylinder 17 upward. During this process, the filter cylinder 17 is moved into the tank body 1 and the tank body 1 comes into contact with the bottom of the tank 6. At this time, the sealing ring 54 is inserted into the sealing groove 55 to seal the tank body 1 and the bottom of the tank 6. Then, the solvent (usually water or ethanol) is injected into the tank body 1 and the bottom of the tank 6 through the liquid inlet pipe 28, so that the solvent covers the tea and herbal materials inside the filter cylinder 17. The solvent is used to extract the tea and herbal materials, and the aroma of the tea and herbal materials is extracted to obtain the extract. When the extracted tea residue and herbal materials are removed, the extract in the bottom 6 and body 1 of the tank is first drained. Then, the cylinder 4 is activated, causing the fixed block 5 to move downwards. During the downward movement of the fixed block 5, the bottom 6 and support shaft 9 of the tank move downwards simultaneously. The downward movement of the bottom 6 of the tank moves the filter cylinder 17 out of the body 1. During the downward movement of the support shaft 9, the roller 12 slides in the vertical guide groove 10. Because the vertical guide groove 10 is vertically set, the roller 12 will not cause the support shaft 9 to rotate axially during the sliding process in the vertical guide groove 10. When the support shaft 9 drives the roller 12 to slide downwards into the rotating groove 11, the roller 12 rotates. The sliding synchronous motion within the tank 11 drives the fixed plate 14, rotating rod 13, and support shaft 9 to rotate axially around the support shaft 9. During the axial rotation of the support shaft 9, the tank bottom 6 rotates synchronously, which in turn causes the filter cylinder 17, which is displaced out of the tank 1, to rotate axially around the support shaft 9. This process causes the filter cylinder 17 to flip, thereby causing the extracted tea and herbal materials in the filter cylinder 17 to be poured into the material pouring box 16 for collection. This eliminates the need for manual pouring using a crane or other auxiliary equipment, making it more convenient, labor-saving, efficient, and flexible. This improves the extraction efficiency, avoids burns, and enhances safety and reliability, thereby increasing the practicality of the extraction device.

[0026] like Figures 1 to 5 As shown, the mounting mechanism includes a first positioning ring 19 fixedly connected to the filter cartridge 17. The first positioning ring 19 abuts against the tray 18. A first through groove 22 and a limiting groove 27 are formed through the tray 18. A limiting block 20 that can be inserted into the limiting groove 27 is fixedly connected to the side of the first positioning ring 19 near the tray 18. A positioning hole 24 is formed through the limiting block 20. A second positioning ring 23 is slidably connected inside the tray 18. The second positioning ring 23 is arc-shaped. One end of the second positioning ring 23 passes through the limiting groove 27 and can be inserted into the positioning hole 24. The other end of the second positioning ring 23 passes through the first through groove 22 and is fixedly connected to the positioning plate 25. A tension spring 26 is fixedly connected between the positioning plate 25 and the inner wall of the first through groove 22. The tension spring 26 is sleeved on the second positioning ring 23. The extension and retraction path of the tension spring 26 is consistent with the movement path of the second positioning ring 23. The bottom wall of the first through groove 22 and the bottom wall of the first positioning ring 19 are on the same plane to facilitate the discharge of the extract at the bottom of the filter cylinder 17.

[0027] In the initial state, the second positioning ring 23 is inserted into the positioning hole 24 to fix the limiting block 20, preventing the limiting block 20 from being pulled out of the limiting groove 27. This, in turn, fixes the filter cylinder 17, preventing it from being pulled out of the tray 18, thus creating a fixed connection between the tray 18 and the filter cylinder 17. During disassembly, the positioning plate 25 is pushed to stretch the tension spring 26, causing it to deform. During this process, the positioning plate 25 rotates axially around the tray 18. Simultaneously, the positioning plate 25 moves the second positioning ring 23 away from the limiting block 20 and slides it out of the positioning hole 24, thereby releasing the installation and fixation between the tray 18 and the filter cylinder 17, completing the disassembly of the filter cylinder 17. This facilitates cleaning and maintenance of the filter cylinder 17, improving the practicality of the extraction device.

[0028] like Figures 6 to 7 As shown, the oscillation mechanism includes a support tube 38 and a connecting tube 39 fixedly connected to a connecting plate 31. An air box 30 is fixedly connected to the connecting plate 31. Both the support tube 38 and the connecting tube 39 pass through the connecting plate 31. A first fixing rod 40 is inserted into the connecting tube 39, and a second fixing rod 51 is inserted into the support tube 38. A first oscillation block 41 is fixedly connected to the end of the first fixing rod 40 away from the connecting tube 39, and a second oscillation block 47 is fixedly connected to the end of the second fixing rod 51 away from the support tube 38.

[0029] like Figure 7 As shown, an air inlet pipe 29 is fixedly connected to one side of the air box 30 and communicates with it. The end of the air inlet pipe 29 away from the air box 30 passes through the tank body 1. A slider 32 is provided inside the air box 30. A crossbar 56 that is inserted into the air inlet pipe 29 is fixedly connected to the end of the slider 32 near the air inlet pipe 29. A first sealing plug 33 that is slidably connected to the air box 30 is fixedly connected to the slider 32. A second air inlet hole 35 and a first air inlet hole 34 are provided through the air box 30. The end of the connecting pipe 39 is fixedly connected to the second air inlet hole 35. The end of the support pipe 38 is fixedly connected to the first air inlet hole 34. The connecting pipe 39 communicates with the second air inlet hole 35. The first air inlet hole 34 communicates with the support pipe 38. An air pump is provided on the bottom bracket 2. The output end of the air pump is fixedly connected to the end of the air inlet pipe 29 that passes through the tank body 1.

[0030] The first sealing plug 33 is used to increase the sealing of the slider 32 in the air box 30. In the initial state, the slider 32 is located between the second air inlet 35 and the first air inlet 34. When the bottom of the tank 6 abuts against the tank body 1, the first oscillating block 41 and the second oscillating block 47 are both located in the filter cartridge 17 and are submerged in the solution. When the air pump is started to inject air into the air inlet pipe 29, the slider 32 moves towards the first air inlet 34. A negative pressure is formed in the space of the slider 32 in the air box 30 near the third air inlet 36, so that the first fixed rod 40 moves upward, thereby synchronously driving the first oscillating block 41 to move upward. Simultaneously, the space of the slider 32 in the air box 30 near the first air inlet 34 is squeezed, thereby pushing the second fixed rod 51 to move downward, thereby driving the second oscillating block 47 to move downward. Conversely, when the air pump draws into the air inlet pipe 29, it can drive the first oscillating block 41 to move downwards and the second oscillating block 47 to move upwards. During the up-and-down movement of the first oscillating block 41 and the second oscillating block 47, the solution in the tank body 1 and the tank bottom 6 is oscillated, thereby causing the solution to flow up and down, so that the solution inside the filter cylinder 17 and the solution outside the filter cylinder 17 can convect, and the tea and herbal materials are tumbled with the solution, thereby accelerating the extraction of tea and herbal materials, and thus improving the quality and efficiency of extraction. Furthermore, the opposite movement of the first oscillating block 41 and the second oscillating block 47 can increase the convection of the solution, thereby improving the extraction efficiency of the solution for tea and herbal materials. Furthermore, in this solution, the first and second oscillating blocks 41 and 47, which are elliptical in shape, move up and down, causing the solution in the tank 1 and the tank bottom 6 to oscillate. This is gentler than the traditional method of using a stirring rod to accelerate the extraction of tea and herbal materials, avoiding damage to the tea and herbal materials caused by vigorous stirring, so as to make the extract clearer and improve the extraction effect of the aroma of tea and herbs. In this design, a cavity is provided between the inner and outer walls of the tank 1, and a heating component is installed inside the cavity. The heating component includes a controller, an electric heating wire, a temperature sensor, etc. The tank 1 can heat the solution. Typically, the solution is heated to a constant temperature of 60-80℃ during the extraction of tea and herbal materials. The specific temperature is adjusted according to the type of tea, humidity, and specific type of herbal material.

[0031] like Figures 7 to 8As shown, a second rotating block 52 is fixedly connected to the end of the connecting plate 31 away from the air box 30. A vertical rod 50 is rotatably connected to the second rotating block 52. Multiple rocking blocks 48 are fixedly connected to the vertical rod 50. A sliding cylinder 42 is slidably connected to the vertical rod 50. A first rotating block 43 is fixedly connected to the sliding cylinder 42. An air cylinder 45 is fixedly connected inside the tank 1. A push rod 44 is inserted into the air cylinder 45. The end of the push rod 44 away from the air cylinder 45 is rotatably connected to the first rotating block 43. A third air inlet 36 is opened through the air box 30. A positioning tube 37 is fixedly connected inside the third air inlet 36. A fixed tube 46 communicating with the air cylinder 45 is fixedly connected to the air cylinder 45. A flexible hose is provided between the fixed tube 46 and the positioning tube 37.

[0032] like Figures 6 to 8 As shown, a second sealing plug 49 is fixedly connected to push rod 44, first fixed rod 40 and second fixed rod 51. A second sealing plug 49 is also fixedly installed at the end of cross rod 56 away from slider 32. The second sealing plug 49 on push rod 44 is slidably connected to air cylinder 45. The second sealing plug 49 on first fixed rod 40 is slidably connected to connecting pipe 39. The second sealing plug 49 on second fixed rod 51 is slidably connected to support pipe 38. The second sealing plug 49 on cross rod 56 is slidably connected to air inlet pipe 29.

[0033] When the air pump is started, it drives the slider 32 to move left and right, simultaneously driving the push rod 44 to slide inside the air cylinder 45. Because the end of the push rod 44 is rotatably connected to the first rotating block 43, the push rod 44 pushes the sliding cylinder 42 to slide on the vertical rod 50 during the sliding process inside the air cylinder 45, and drives the vertical rod 50 to rotate around the second rotating block 52. Then, during the reciprocating movement of the push rod 44 inside the air cylinder 45, it drives the vertical rod 50 to swing around the second rotating block 52, which in turn drives the rocking block 48 to swing in the solution. The swing amplitude of the rocking block 48 in the solution will not touch the filter cylinder 17, and the swing of the vertical rod 50 and the rocking block 48 can increase the convection of the solution in the tank 1 and the filter cylinder 17, thereby making the extract more uniform. On the one hand, it improves the extraction efficiency, and on the other hand, it improves the extraction effect of tea and herbal aroma.

[0034] like Figures 1 to 5 As shown, a filter plate 53 is fixedly connected inside the tank bottom 6. The filter plate 53 is located on the lower side of the tray 18. A liquid outlet pipe 7 connected to the tank bottom 6 is fixedly connected to the side of the tank bottom 6 away from the tank body 1.

[0035] The extract is discharged through the outlet pipe 7, which is equipped with a solenoid valve.

[0036] The filter plate 53 is used to further filter the extracted liquid, thereby preventing impurities from being mixed in with the extracted material and thus improving the extraction effect.

[0037] In this design, the filter cylinder 17 is made of a mesh plate. The particle size of the tea and herbal materials is much smaller than the gaps in the mesh plate of the filter cylinder 17. The filter cylinder 17 has a filtering effect on the tea and herbal materials. However, in this design, the height of the solution cannot be too high to avoid the particulate tea and herbal materials being carried out during the up-and-down movement of the first oscillating block 41 and the second oscillating block 47.

[0038] A method of using a natural aroma extraction device for tea and herbs, the method of use including: S1: Wash the tea leaves and herbs thoroughly and let them air dry. S2: Knead the tea leaves to accelerate the release of aroma during subsequent tea infusion; S3: Place the tea leaves and herbal materials into the filter cylinder 17, start the cylinder 4 in the tilting mechanism, and drive the bottom of the can 6 and the filter cylinder 17 to move upward. The filter cylinder 17 moves upward into the can body 1, and the bottom of the can 6 moves upward to abut against the can body 1, and drives the sealing ring 54 to insert into the sealing groove 55 to seal between the can body 1 and the bottom of the can 6. S4: Inject the solution into the tank body 1 and the tank bottom 6 through the inlet pipe 28, so that the solution level covers the tea leaves and herbal materials; S5: The aroma of tea leaves and herbal materials is extracted into a solution to obtain an extract. The air pump in the oscillation mechanism is started to drive the first oscillation block 41 and the second oscillation block 47 to move up and down. During the up and down movement of the first oscillation block 41 and the second oscillation block 47, the solution in the tank body 1 and the bottom of the tank 6 is oscillated, thereby causing the solution to flow up and down, so that the solution in the filter cylinder 17 and the solution outside the filter cylinder 17 can be convected, and the tea and herbal materials are tumbled with the solution, thereby accelerating the extraction of tea and herbal materials and accelerating the aroma extraction efficiency of tea and herbal materials. S6: The extract is discharged through the outlet pipe 7, and the cylinder 4 in the tilting mechanism is activated, causing the fixed block 5 to move downwards. Simultaneously, the filter cylinder 17 moves out of the tank body 1. During the downward movement of the fixed block 5, the tank bottom 6 and support shaft 9 move downwards simultaneously. The downward movement of the tank bottom 6 simultaneously moves the filter cylinder 17 out of the tank body 1, while the downward movement of the support shaft 9 causes the roller 12 to slide within the vertical guide groove 10. When the support shaft 9 drives the roller 12 to slide downwards into the rotating groove 11, the roller 12 sliding within the rotating groove 11 simultaneously drives the fixed plate 14, rotating rod 13, and support... Shaft 9 rotates axially around the support shaft 9. During the axial rotation of the support shaft 9, the bottom 6 of the tank rotates synchronously, which in turn causes the filter cylinder 17, which is displaced out of the tank body 1, to rotate axially around the support shaft 9. During this process, the filter cylinder 17 is rotated, thereby causing the extracted tea and herbal materials in the filter cylinder 17 to be poured into the pouring box 16 for collection. There is no need for manual pouring using a crane or other auxiliary means, which is more convenient, labor-saving, efficient and flexible, thereby improving the extraction efficiency, avoiding burns, making it safer and more reliable, and increasing the practicality of the extraction device.

[0039] S7: The extract can be further concentrated under reduced pressure (usually below 50°C) to further concentrate the aroma.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of the invention, all of which fall within the scope of protection claimed by the present invention.
