Description

Technical Field

[0001] This utility model relates to the field of extraction device technology, and in particular to a device for extracting Artemisia argyi essential oil. Background Technology

[0002] Artemisia argyi, a traditional medicinal plant, has an extract called Artemisia argyi essential oil, which is rich in active ingredients such as eucalyptol, thujone, and α-thujone. It has antibacterial, anti-inflammatory, mosquito-repellent, and nerve-soothing effects and is widely used in the fields of medicine, daily chemicals, and health preservation. In the pharmaceutical field, it is used to make moxibustion patches and anti-inflammatory ointments. In the daily chemical field, it is a core raw material for mosquito repellent sprays and essential oil soaps. In the health preservation field, it is often used in aromatherapy and meridian massage.

[0003] The existing technology has obvious adjustment defects in traditional devices: manual crank stirring relies on human experience to control the stirring angle and force, which is prone to uneven stirring, resulting in local accumulation of mugwort. The essential oil in the accumulated area cannot be fully dissolved, reducing the extraction efficiency, or the mugwort fiber is broken due to excessive force. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a device for extracting Artemisia argyi essential oil.

[0005] This utility model is achieved using the following technical solution: a mugwort essential oil extraction device, comprising an extraction tank, a fixed rod rotatably connected to the inner wall of the extraction tank, a partition plate fixedly connected to the outer wall of the fixed rod, the right side of the fixed rod penetrating through the inner wall of the extraction tank and extending therefrom, several fixed rods being provided, a guide block fixedly connected to the outer wall of the partition plate, a protective cover fixedly connected to the outer wall of the extraction tank, an adjusting block fixedly connected to the outer wall of the protective cover, an adjusting screw threadedly connected to the inner wall of the adjusting block, the adjusting screw slidably connected to the outer wall of the protective cover, the adjusting screw penetrating through the inner wall of the protective cover and extending therefrom, an adjusting rod rotatably connected to one end of the adjusting screw penetrating through the protective cover, an adjusting plate fixedly connected to the end of the adjusting rod away from the adjusting screw, and a rotating... A rotating rod is rotatably connected to the outer wall of a rotating rod, with the inner wall of the end of the driving rod away from the rotating rod fixedly connected to the outer wall of a fixed rod. A rotating rod is fixedly connected to the outer wall of an adjusting plate, with a driving rod rotatably connected to the outer wall of the rotating rod, and the end of the driving rod away from the rotating rod fixedly connected to the outer wall of the fixed rod. An adjusting plate is fixedly connected to the end of an adjusting rod away from the adjusting screw, with a rotating rod 3 fixedly connected to the outer wall of the adjusting plate, with a driving rod 3 rotatably connected to the outer wall of the rotating rod, and the end of the driving rod away from the rotating rod fixedly connected to the outer wall of the fixed rod. A rotating rod 4 is rotatably connected to the outer wall of the adjusting plate, with a driving rod 4 rotatably connected to the outer wall of the rotating rod, and the end of the driving rod away from the rotating rod fixedly connected to the outer wall of the fixed rod.

[0006] As a further improvement to the above scheme, a plurality of spacers and a plurality of flow guide blocks are provided, and the plurality of flow guide blocks are arranged symmetrically with respect to the spacers.

[0007] Through the above technical solution, the protective cover fixed to the outer wall of the extraction tank provides protection and support for the adjustment mechanism. The adjusting screw connected to the inner wall of the adjusting block is rotated, so that the adjusting screw slides along the inner wall of the protective cover and extends through it. The adjusting rod connected to the extended end of the adjusting screw moves synchronously with the screw, thereby driving the adjusting plate one and adjusting plate two fixed at both ends of the adjusting rod to move synchronously.

[0008] As a further improvement to the above solution, a sealing plate is hinged to the outer wall of the extraction tank, a limiting groove is opened on the front of the extraction tank, a limiting block is slidably connected to the inner wall of the limiting groove, and the outer wall of the limiting block is slidably connected to the surface of the sealing plate.

[0009] As a further improvement to the above solution, a limiting ring one is fixedly connected to the inner wall of the extraction tank, and a limiting ring two is fixedly connected to the inner wall of the extraction tank. An isolation plate is slidably connected to the bottom of the limiting ring one, and the bottom of the isolation plate is slidably connected to the top of the limiting ring two.

[0010] As a further improvement to the above solution, a baffle plate is slidably connected to the surface of the second limiting ring, and an air inlet pipe is connected to the bottom of the inner wall of the extraction tank.

[0011] As a further improvement to the above solution, the air inlet pipe penetrates the inner wall of the extraction tank and extends therein, and a support leg is fixedly connected to the bottom of the extraction tank.

[0012] As a further improvement to the above solution, three support legs are provided, and the three support legs are evenly arranged around the center of the extraction tank.

[0013] Through the above technical solution, the air inlet pipe connected to the bottom of the inner wall of the extraction tank extends through the tank wall to the outside, and can be connected to air source equipment such as air pumps. Gas, such as steam or inert gas, is delivered into the extraction tank through the air inlet pipe: if steam is delivered, it can heat the extraction medium and promote the volatilization and dissolution of Artemisia argyi essential oil; if inert gas is delivered, it can prevent the essential oil from oxidizing and deteriorating during the extraction process. At the same time, the airflow disturbance enhances the circulation of the medium and improves the extraction efficiency. The three fixed support legs at the bottom of the extraction tank are evenly distributed around the center of the tank to form a stable triangular support structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention provides protection and support for the adjustment mechanism through a protective cover fixed to the outer wall of the extraction tank. Rotating the adjusting screw, which is threaded onto the inner wall of the adjusting block, causes the adjusting screw to slide along the inner wall of the protective cover and extend through it. The adjusting rod, rotatably connected to the extended end of the adjusting screw, moves synchronously with the screw, thereby driving the adjusting plates 1 and 2, fixed at both ends of the adjusting rod, to move synchronously, completing the transmission and conversion of adjustment power. Rotating rods 1 and 2, fixed to the outer wall of adjusting plate 1, move with adjusting plate 1, respectively driving driving rods 1 and 2, rotatably connected to the outer wall, to swing. Simultaneously, rotating rods 3 and 4, located on the outer wall of adjusting plate 2, drive driving rods 3 and 4, rotatably connected to the outer wall, to swing synchronously, forming a multi-drive rod collaborative transmission structure. The ends of driving rods 1, 2, 3, and 4, away from the adjusting plate, are all fixedly connected to the outer wall of the fixed rods. Therefore, the swinging of each driving rod synchronously drives several fixed rods to rotate along the inner wall of the extraction tank. The rotation angle of the fixed rods changes according to the sliding depth of the adjusting screw, preventing the accumulation of Artemisia argyi inside the extraction tank from affecting its extraction efficiency and quality.

[0016] This invention features an air inlet pipe extending from the bottom of the inner wall of the extraction tank to the outside, allowing connection to air pumps or other gas supply equipment. Gases, such as steam or inert gases, are supplied to the tank through the inlet pipe. Steam heats the extraction medium and promotes the volatilization and dissolution of Artemisia argyi essential oil; inert gases prevent oxidation and deterioration of the essential oil during extraction. Simultaneously, airflow disturbance enhances medium circulation and improves extraction efficiency. Three fixed support legs at the bottom of the extraction tank are evenly distributed around the center of the tank, forming a stable triangular support structure that elevates the tank to a certain height, preventing corrosion or contamination from direct contact with the ground. After the sealing plate closes, a limiting block slides along the limiting groove on the front of the extraction tank, engaging with the groove on the surface of the sealing plate, thus mechanically restricting the sealing plate. The rotation of the extraction tank; the limiting ring one and limiting ring two on the inner wall of the extraction tank jointly support the isolation plate, fixing it at the middle height of the tank body to form a raw material isolation layer: the mugwort raw material is placed directly on the isolation plate, avoiding the raw material from sinking directly to the bottom of the tank and directly contacting the airflow and steam output from the air inlet pipe. The layered design of the isolation plate and the barrier plate allows the sliding of the barrier plate on the surface of the limiting ring two to cover the space opening between the bottom of the tank and the isolation plate when the extraction is completed and the isolation plate needs to be removed to clean the residual and blocked mugwort. At this time, the isolation plate is removed, and the residual mugwort fragments or incompletely extracted raw material will fall on the barrier plate instead of falling directly to the bottom of the tank, avoiding the accumulation of impurities at the bottom of the tank that block the air inlet pipe or contaminate the medium for the next extraction. After cleaning, the sliding barrier plate can collect and process the fragments, simplifying the cleaning process inside the tank. Attached Figure Description

[0028] Several partition plates 3 and several flow guide blocks 4 are provided, and the flow guide blocks 4 are symmetrically arranged with the partition plates 3 as the center.

[0029] The outer wall of the extraction tank 1 is hinged with a sealing plate 19. A limiting groove 20 is opened on the front of the extraction tank 1. A limiting block 21 is slidably connected to the inner wall of the limiting groove 20. The outer wall of the limiting block 21 is slidably connected to the surface of the sealing plate 19.

[0030] The inner wall of extraction tank 1 is fixedly connected to a limiting ring 22, and the inner wall of extraction tank 1 is fixedly connected to a limiting ring 23. The bottom of the limiting ring 22 is slidably connected to an isolation plate 24, and the bottom of the isolation plate 24 is slidably connected to the top of the limiting ring 23.

[0031] The surface of the limiting ring 23 is slidably connected to the baffle plate 25, and the bottom of the inner wall of the extraction tank 1 is connected to the air inlet pipe 26.

[0032] The air inlet pipe 26 penetrates the inner wall of the extraction tank 1 and extends thereto, and the bottom of the extraction tank 1 is fixedly connected to the support leg 27.

[0033] There are three support legs 27, which are evenly distributed around the center of the extraction tank 1.

[0034] The implementation principle of the artemisia essential oil extraction device in this application embodiment is as follows: the protective cover 5 fixed to the outer wall of the extraction tank 1 provides protection and support for the adjustment mechanism. The adjusting screw 7 threadedly connected to the inner wall of the adjusting block 6 is rotated, causing the adjusting screw 7 to slide along the inner wall of the protective cover 5 and extend through it. The adjusting rod 8 rotatably connected to the extended end of the adjusting screw 7 moves synchronously with the screw, thereby driving the adjusting plate 1 9 and adjusting plate 2 14 fixed at both ends of the adjusting rod 8 to move synchronously, completing the transmission and conversion of the adjustment power. The rotating rod 10 and rotating rod 2 12 fixed to the outer wall of the adjusting plate 1 9 respectively drive the driving rod rotatably connected to the outer wall as the adjusting plate 1 9 moves. Drive rod 11 and drive rod 2 13 swing; at the same time, the rotating rod 3 15 and rotating rod 4 17 on the outer wall of the adjusting plate 2 14 drive rod 3 16 and drive rod 4 18 connected to the outer wall to swing synchronously, forming a multi-drive rod cooperative transmission structure. The ends of drive rod 11, drive rod 2 13, drive rod 3 16 and drive rod 4 18 away from the adjusting plate are all fixedly connected to the outer wall of the fixed rod 2. Therefore, the swing of each drive rod synchronously drives several fixed rods 2 to rotate along the inner wall of the extraction tank 1. The rotation angle of the fixed rod 2 is changed by the sliding depth of the adjusting screw 7, so as to avoid the accumulation of Artemisia argyi inside the extraction tank 1 from affecting its extraction efficiency and extraction quality. An air inlet pipe 26, connected to the bottom of the inner wall of extraction tank 1, extends through the tank wall to the outside and can be connected to air source equipment such as an air pump. Gas, such as steam or inert gas, is supplied to the interior of extraction tank 1 through the air inlet pipe 26. If steam is supplied, it can heat the extraction medium and promote the volatilization and dissolution of Artemisia argyi essential oil. If inert gas is supplied, it can prevent the essential oil from oxidizing and deteriorating during extraction. Simultaneously, airflow disturbance enhances medium circulation and improves extraction efficiency. Three fixed support legs 27 at the bottom of extraction tank 1 are evenly distributed around the center of the tank, forming a stable triangular support structure that raises extraction tank 1 to a certain height, preventing corrosion or contamination caused by direct contact between the tank bottom and the ground. After the sealing plate 19 is closed, the limiting block 21 slides along the limiting groove 20 on the front of extraction tank 1, causing it to engage in the groove on the surface of the sealing plate 19, thus restricting the rotation of the sealing plate 19 through mechanical blocking. The limiting ring 22 and limiting ring 23 of the wall together support the isolation plate 24, fixing it at the middle height of the tank to form a raw material isolation layer: the mugwort raw material is placed directly on the isolation plate 24, avoiding the raw material from sinking directly to the bottom of the tank and coming into direct contact with the airflow and steam output from the air inlet pipe 26. The layered design of the isolation plate 24 and the barrier plate 25 allows the barrier plate 25 on the surface of the limiting ring 23 to cover the space between the bottom of the tank and the isolation plate 24 when the extraction is completed and the isolation plate 24 needs to be removed to clean the residual and blocked mugwort. At this time, the isolation plate 24 is removed, and the residual mugwort fragments or incompletely extracted raw material will fall on the barrier plate 25 instead of falling directly to the bottom of the tank, avoiding the accumulation of impurities at the bottom of the tank that block the air inlet pipe 26 or contaminate the medium for the next extraction. After cleaning, the debris can be collected and processed by sliding the barrier plate 25, simplifying the cleaning process inside the tank.

[0035] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
