Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0028] Please see Figures 1-5 The present invention will describe the above technical solution in detail through the following embodiments:

[0029] An extraction device for heavy metal detection in traditional Chinese medicinal materials, comprising:

[0030] Digester 1 includes a microwave box 11, which emits microwaves. A protective door 12 is horizontally rotatably mounted on the front side of the microwave box 11. Limiting structures are provided between the top two sides of the protective door 12 and the microwave box 11, which limit the protective door 12 to rotate downwards by a maximum of 90°. A drive assembly is provided on the bottom surface inside the microwave box 11. Guide assemblies are provided on both sides of the drive assembly and the inside of the protective door 12. A tray assembly 2 is connected to the guide assembly. The movement direction of the tray assembly 2 is limited by the guide assembly. A turntable assembly 3 is snapped onto the top surface of the tray assembly 2. The turntable assembly 3 is connected to the drive assembly. When the drive assembly is working, it can drive the turntable assembly 3 to rotate.

[0031] The bottom inner side of the protective door 12 is rotatably connected to the bottom front side of the microwave box 11 via a hinge.

[0032] The top of the protective door 12 and the microwave box 11 should also be equipped with known locking structures such as door locks to ensure locking between the protective door 12 and the microwave box 11.

[0033] The limiting structure is a folding rod 13, which includes two metal rods. The heads of the two metal rods are rotatably connected by pins, and the tails of the two metal rods are rotatably connected to the microwave box 11 and the protective door 12 by pins respectively.

[0034] When the protective door 12 is rotated to a horizontal position, the folding rod 13 is fully extended. At this time, the protective door 12, the folding rod 13 and the microwave box 11 form a triangle, and the folding rod 13 will prevent the protective door 12 from continuing to rotate.

[0035] The drive assembly includes a power source 14, which extends upward into the microwave box 11 and is connected to a transmission block 15, the transmission block 15 having an arched cross-section.

[0036] The power source 14 uses an electric motor, and the transmission block 15 is connected to the output shaft of the power source 14.

[0037] When the power source 14 is working, it can drive the transmission block 15 to rotate.

[0038] The guide assembly includes a slide 16 and a guide rail 17. The slide 16 is located on both sides of the transmission block 15, and the guide rail 17 is located inside the protective door 12. The guide rail 17 and the slide 16 are aligned, and the internal shape of the guide rail 17 is the same as that of the slide 16.

[0039] The slide 16 adopts a T-shaped groove, and the upper part of the guide rail 17 is axially continuous, and the upper part of the guide rail 17 is also a T-shaped groove.

[0040] The tray assembly 2 includes a tray 21, which is engaged with the slide groove 16 and the guide rail 17 via a slider 23 and is able to slide along the slide groove 16 and the guide rail 17.

[0041] The tray 21 and slider 23 are made of plastic and are molded as one piece. The slider 23 is adapted to the slide 16 and the guide rail 17.

[0042] The slide 16 and guide rail 17 are used to limit the movement direction of the slider 23, thereby limiting the movement direction of the tray 21.

[0043] A limiting groove 24 is provided through the middle of the pallet 21 and extends forward. The width of the limiting groove 24 is the same as the minimum width of the transmission block 15. A rotating groove 25 is provided at the end of the limiting groove 24 and at the center of the pallet 21. The inner diameter of the rotating groove 25 is greater than the maximum width of the transmission block 15.

[0044] The axis of the limiting groove 24 is located to the left of the axis of the tray 21.

[0045] Since the cross-section of the transmission block 15 is arched, the side of the transmission block 15 includes a curved surface and a flat surface. The distance from the flat surface to the rotation axis of the transmission block 15 is shorter. Therefore, the transmission block 15 can only slide into the limiting groove 24 when the flat surface of the side of the transmission block 15 faces right and is parallel to the edge of the limiting groove 24. At this time, the tray 21 can slide into the microwave box 11.

[0046] Once the tray 21 has slid completely into the microwave oven 11, the transmission block 15 is positioned exactly at the center of the rotating slot 25. At this point, the transmission block 15 can rotate freely.

[0047] A limiting ring 22 is provided on the top surface of the tray 21 and the rotating groove 25 concentrically. A positioning notch 26 is provided on the top of the limiting ring 22 and in the direction of the extension line of the limiting groove 24.

[0048] The limiting ring 22 and the tray 21 are integrally molded from the same material. The limiting ring 22 is C-shaped, and the opening of the limiting ring 22 is located above the limiting groove 24, thereby facilitating the passage of the transmission block 15.

[0049] The turntable assembly 3 includes a base 31, the bottom surface of which is provided with a connecting groove 35. The width of the connecting groove 35 is the same as the minimum width of the transmission block 15. The side of the base 31 and located in the direction of the extension line of the connecting groove 35 are provided with a positioning protrusion 34.

[0050] The outer diameter of the base 31 is the same as the inner diameter of the limiting ring 22, and the thickness of the base 31 is greater than the height of the limiting ring 22.

[0051] The base 31 is placed inside the limiting ring 22 and can rotate within the limiting ring 22. The limiting ring 22 is used to prevent the base 31 from moving left or right.

[0052] When the base 31 rotates, when the positioning protrusion 34 aligns with the positioning notch 26, the connecting groove 35 is located directly above the limiting groove 24, and the opening of the connecting groove 35 faces the same direction as the opening of the limiting groove 24.

[0053] At this time, the transmission block 15 can slide along the connecting groove 35 and the limiting groove 24.

[0054] A top cover 32 is fixedly installed on the top of the base 31 by screws. Several circular through holes are evenly distributed on the top cover 32. The screws are made of plastic.

[0055] An explosion-proof container 33 is snapped together between the base 31 and the top cover 32. The explosion-proof container 33 is aligned with the through hole on the top cover 32. A digestion vessel 4 is slidably installed inside the explosion-proof container 33, and the digestion vessel 4 is inserted into the explosion-proof container 33 from above the top cover 32. The digestion vessel 4 is used to hold the sample and the digestion solvent.

[0056] When the operator uses this device, they open the protective door 12 and rotate it downwards to a horizontal position. At this time, the folding rod 13 will pull the head of the protective door 12 to prevent it from rotating excessively.

[0057] Rotate the turntable assembly 3 so that the positioning protrusion 34 is aligned with the positioning notch 26. At this time, the opening of the connecting groove 35 and the opening of the limiting groove 24 face the same direction.

[0058] Then pull the tray 21 outwards, so that the tray 21 slides along the slide 16 to the top of the guide rail 17. At this time, the turntable assembly 3 will move with the tray 21 to the protective door 12.

[0059] Insert the digestion vessel 4 into the explosion-proof container 33 from above the top cover 32.

[0060] When inserting the containers, it is important to note that if the number of digestion containers 4 is less than the number of explosion-proof containers 33, the digestion containers 4 need to be arranged at intervals, preferably inserted along the diagonal.

[0061] Then rotate the turntable assembly 3 again to align the positioning protrusion 34 with the positioning notch 26. Next, push the tray 21 into the microwave oven 11 until it can no longer move.

[0062] At this time, the transmission block 15 is located at the center of the rotating groove 25 and is exactly at the end of the connecting groove 35.

[0063] Then, rotate the protective door 12 upwards to a vertical position and lock it using a door lock or similar device. Next, control the power source 14 to operate, driving the transmission block 15 to rotate, thereby driving the turntable assembly 3 to rotate. Microwaves emitted from the microwave box 11 are used to heat and digest the substances inside the digester 4.

[0064] During this process, there is no need to move the turntable component 3.

[0065] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
