[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] Example 1: Please refer to Figures 1-4This utility model provides a multi-angle rotary evaporator, mainly composed of a base 1, a water bath 2, a lifting mechanism 3, a fixing ring 4, an explosion-proof net 5, a buckle 6, a glass cover 7, an angle adjustment structure 8, a connector 9, a condenser 10, a rotating flask 11, and a collection bottle 12. The base 1 serves as the supporting foundation for the entire device, on which the water bath 2 is mounted. The water bath 2 provides the heating environment required for rotary evaporation. The top of the water bath 2 is covered with a hemispherical glass cover 7. The function of the glass cover 7 is to reduce heat loss and maintain a uniform water bath temperature, especially for applications requiring precise temperature control. In the experiment, the glass cover 7 is made of transparent material to facilitate observation of the evaporation inside the rotating flask 11. A fixing ring 4 is set on the outer bottom of the glass cover 7, and a hemispherical explosion-proof net 5 is set on the outside of the glass cover 7. The bottom of the explosion-proof net 5 is fixed to the fixing ring 4. The explosion-proof net 5 plays a safety protection role, preventing personnel injury caused by accidental breakage of the rotating flask 11 or the glass cover 7 inside the water bath 2. The fixing ring 4 is connected to the water bath 2 by a buckle 6. This connection method facilitates the disassembly and installation of the explosion-proof net 5 and the glass cover 7, and facilitates the cleaning and maintenance of the water bath 2 and the rotating flask 11.

[0021] The base 1 is equipped with a lifting platform 3. The lifting plate of the lifting platform 3 can move up and down to adjust the height of the angle adjustment structure 8. The angle adjustment structure 8 is installed on the lifting plate of the lifting platform 3. The angle adjustment structure 8 is used to adjust the angle of the connector 9, thereby adjusting the tilt angle of the rotating bottle 11. The angle adjustment structure 8 includes a housing 81, which is fixed to the lifting plate of the lifting platform 3. A rotating shaft 82 is rotatably installed between the front and rear inner walls of the housing 81. The side of the connector 9 is fixed to the end of the rotating shaft 82. Thus, when the rotating shaft 82 rotates... When in motion, connector 9 rotates accordingly, thereby causing the rotating bottle 11 to change its angle. A worm gear 83 is installed on the rotating shaft 82, and a worm 84 is rotatably installed between the upper and lower inner walls of the housing 81. The worm 84 cooperates with the worm gear 83. By rotating the worm 84, the worm gear 83 can be driven to rotate, thereby driving the rotating shaft 82 to rotate. A servo motor 85 is installed on the housing 81. The output shaft of the servo motor 85 is connected to the shaft of the worm 84. The servo motor 85 can precisely control the rotation angle of the worm 84, thereby achieving precise adjustment of the angle of the rotating bottle 11.

[0022] The connector 9 has a condenser 10 and a rotating flask 11 connected to its two interfaces respectively. The condenser 10 is used to condense the vapor evaporated in the rotating flask 11 into liquid. The bottom of the condenser 10 is connected to a collection bottle 12, which is used to collect the condensed liquid. The body of the rotating flask 11 is located in the space enclosed by the water bath 2 and the glass cover 7. In this way, the water bath 2 can heat the liquid in the rotating flask 11 to promote evaporation.

[0023] The fixed ring 4 and the explosion-proof net 5, as well as the glass cover 7, all have grooves on their sides for the neck of the rotating bottle 11 to pass through. These two grooves overlap each other and their function is to ensure that the neck of the rotating bottle 11 can pass smoothly through the fixed ring 4, the explosion-proof net 5 and the glass cover 7 and connect with the connector 9.

[0024] Example 2: Based on Example 1, the bottom of the fixing ring 4 is provided with three positioning posts 14 arranged in a circular array. The top of the water bath 2 is provided with positioning holes 13 corresponding to the positions of the three positioning posts 14. The positioning posts 14 can be inserted into the positioning holes 13. When installing the fixing ring 4, the positioning posts 14 are aligned with the positioning holes 13 and inserted, which can quickly and accurately position the fixing ring 4 and the water bath 2, improve the installation efficiency, and at the same time ensure the stability of the relative position between the fixing ring 4 and the water bath 2, and avoid shaking during use.

[0025] Two symmetrical positioning protrusions 16 are provided on the bottom outer side of the glass cover 7. The bottom of the fixing ring 4 has positioning grooves 15 corresponding to the positions of the two positioning protrusions 16. The positioning protrusions 16 can be inserted into the positioning grooves 15. When the positioning protrusions 16 are inserted into the positioning grooves 15, the relative position between the glass cover 7 and the fixing ring 4 can be further ensured to be accurate, so that the glass cover 7 can be stably covered on the water bath 2, thereby improving the overall stability of the device.

[0026] In actual use, the angle of the rotating flask 11 can be adjusted according to experimental needs. For example, when it is necessary to speed up the evaporation, the servo motor 85 can drive the worm gear 84 to rotate, so that the worm wheel 83 drives the rotating shaft 82 to rotate, thereby adjusting the tilt angle of the rotating flask 11, so that the liquid in the rotating flask 11 is heated more evenly and the evaporation efficiency is improved. In addition, in actual use, it is possible to choose whether to cover the top opening of the water bath 2 with a glass cover 7 according to experimental needs. When the glass cover 7 is not covered, after the rotating flask 11 is placed in the water bath 2, the fixing ring 4 can be directly connected to the water bath 2 with the buckle 6.

[0027] Example 3: The multi-angle rotary evaporator in this example is basically the same in structure as Example 1 and Example 2, but some details have been optimized. For example, a more robust connection method, such as welding or snap-fit ​​connection, can be used to connect the fixing ring 4 and the explosion-proof net 5, so as to ensure that the explosion-proof net 5 will not loosen or fall off during use. In terms of the material selection of the glass cover 7, a glass material with better heat resistance and transparency can be selected to improve the service life of the glass cover 7 and the observation effect. A limit switch can be installed on the lifting plate of the lifting machine 3 to prevent the lifting plate from exceeding the specified range during the lifting process and improve the safety of the device.

[0028] Operating Procedure: First, add the sample to be evaporated to the rotating flask 11. Then, control the rotating flask 11 to descend using the lifting mechanism 3, immersing the lower part of the flask 11 in the water bath 2. Depending on the experimental requirements, choose whether to cover the top opening of the water bath 2 with a glass cover 7. Then, place the fixing ring 4 on top of the water bath 2, ensuring that the positioning post 14 is accurately inserted into the positioning hole 13, guaranteeing the correct relative position of the fixing ring 4 and the water bath 2. Connect the fixing ring 4 to the water bath 2 using the buckle 6. Finally, start the instrument to begin the evaporation operation.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
