[0026] The base 1 provides stable support as the foundation of the entire device, and the support shell 2 is located on the top rear side of the base, which is used to install and support other components, especially the fixed disc 11 and its attached parts. The fixed disc 11 can slide up and down on the front side of the support shell 2, which allows users to adjust the height of the rotating part 3 according to the experimental requirements, and adapt to different sizes of distillation bottles 9, increasing the applicability and flexibility of the device. The rotating part 3 is fixed on the front side of the fixed disc 11, responsible for driving the distillation bottle 9 to rotate. The fixed tube 4 is inclinedly arranged on the inner wall of the rotating part 3, used to connect the distillation bottle 9 and the condenser tube 5. The inclined design helps to guide the steam flow and improve the evaporation efficiency. The condenser tube 5 is connected to one end of the fixed tube 4, used to cool the evaporated solvent vapor to make it re-liquefy. The collection bottle 6 is located at the bottom of the condenser tube 5, directly contacting the top of the base 1, which is convenient for collecting the condensed solvent and also helps to maintain the stability of the collection bottle 6. The splash-proof bottle 8 is connected to the end of the fixed tube 4 away from the condenser tube 5, used to prevent the solvent from splashing during evaporation, protecting the condenser tube 5 and other components from contamination. The water bath 10 is fixed on the other side of the top of the base 1, specially used to place the distillation bottle 9, providing the necessary heat to promote solvent evaporation. At the same time, the water bath method can heat the sample more evenly, suitable for the evaporation needs of various solvents.

[0027] Further, the rotating part 3 is fixedly connected with a positioning plug rod 301 on the rear side, and the positioning plug rod 301 is vertically penetrated with a first mounting hole 302.

[0028] Further, the front side of the fixed disc 11 is rotationally connected with a positioning sleeve 110, and the positioning sleeve 110 is vertically penetrated with a second mounting hole 111. The second mounting hole 111 and the first mounting hole 302 are threadedly connected with a positioning bolt 112.

[0029] Through the cooperation of the positioning plug rod 301 and the positioning sleeve 110, and the fixation of the positioning bolt 112, it can ensure that the rotating part 3 is stable at any height position, avoiding experimental errors caused by device shaking. Users can adjust the position of the rotating part 3 by simple sliding and rotating operation, and then quickly fix it by tightening the positioning bolt 112, greatly simplifying the operation process.

[0030] Further, the surface of the positioning sleeve 110 is fixedly sleeved with a worm gear 12, the top of the worm gear 12 is meshingly connected with a worm 13, the surface of the worm 13 is rotationally connected with a rotating frame, the rotating frame is fixedly connected between the front side of the fixed disc 11 and the worm 13, and one end of the worm 13 extends to the outside of the rotating frame and is fixedly connected with a first knob 14.

[0031] By turning knob 14, worm gear 13 rotates, which in turn drives worm wheel 12 to rotate. The rotation of worm wheel 12 causes the positioning sleeve 110 and its rotating component 3 to be finely adjusted, thereby achieving precise positioning of rotating component 3. After rotating component 3 is adjusted to the required position, the position of rotating component 3 is fixed by tightening positioning bolt 112.

[0032] By turning knob 14, worm gear 13 rotates, which in turn drives worm wheel 12 to rotate. The rotation of worm wheel 12 causes the positioning sleeve 110 and its rotating component 3 to be finely adjusted, thereby achieving precise positioning of rotating component 3. After rotating component 3 is adjusted to the required position, it is fixed on the fixed plate 11 by tightening the positioning bolt 112 to ensure that rotating component 3 will not loosen during operation.

[0033] Furthermore, a vertical guide groove 201 is provided on the front side of the support shell 2, and a lifting plate 15 is slidably connected inside the support shell 2. A connecting rod 150 is fixedly connected to the center of the front side of the lifting plate 15, and the connecting rod 150 extends to the front side of the support shell 2 and is slidably connected to the inner wall of the guide groove 201.

[0034] Furthermore, sliding grooves 202 are provided on the left and right sides of the inner wall of the guide groove 201, and sliders 151 are fixedly connected to both sides of the lifting plate 15, with sliders 151 and sliding grooves 202 slidably connected.

[0035] Furthermore, the lifting plate 15 has a threaded rod 16 connected to the center of the interior. The bottom of the threaded rod 16 is rotatably connected to the bottom of the inner wall of the support shell 2, and the top of the threaded rod 16 extends to the top of the support shell 2 and is rotatably connected to it.

[0036] Furthermore, a second knob 17 is fixedly connected to the top of the threaded rod 16.

[0037] By rotating knob 17, threaded rod 16 rotates accordingly. Since lifting plate 15 is threadedly connected to threaded rod 16, the rotation of threaded rod 16 causes lifting plate 15 to move up and down. Connecting rod 150 slides up and down in guide groove 201, and slider 151 slides in slide groove 202, ensuring that lifting plate 15 remains stable during up and down movement and avoiding skewness or jamming. The up and down movement of lifting plate 15 causes fixed plate 11 and its rotating component 3 to move together, thereby realizing the height adjustment of rotating component 3.

[0038] Through the above design, this rotary evaporator achieves high flexibility and ease of operation. Height adjustment is achieved through the combination of threaded rod 16 and guide groove 201, and fine adjustment is achieved through the worm gear 12 and worm 13 mechanism, ensuring the stability and accuracy of the equipment during operation.

[0039] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
