Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of rotary evaporators, and in particular relates to a rotary evaporator with a limiting function for extracting medicinal liquid. Background Technology
[0002] Rotary evaporators are a type of high-efficiency evaporation instrument widely used in laboratories. Their working principle is based on vacuum distillation and rotation. By using a vacuum pump to reduce the pressure in the system and create a reduced pressure environment, the boiling point of the liquid is lowered, thus allowing it to evaporate rapidly at a relatively low temperature. At the same time, the evaporation flask rotates in a constant-temperature water bath or oil bath, causing the material to form a thin film on the flask wall, increasing the evaporation area and improving the evaporation efficiency.
[0003] Commercially available rotary evaporators have good extraction capabilities, but due to the lack of limiting structures, the collection bottle may fall during collection due to improper connection and increased internal gravity, causing the collected liquid to spill out. This not only wastes materials but also significantly affects extraction efficiency. Utility Model Content

[0040] The structure of this utility model will now be described in detail with reference to the accompanying drawings.
[0041] like Figures 1 to 4 As shown in the figure, the rotary evaporator with limiting function for drug extraction provided in this embodiment of the present invention includes:
[0042] Base 1;
[0043] Evaporator 2: The base 1 of evaporator 2 is fixedly connected to the upper surface of the base 1;
[0044] Rotating mechanism 3: Rotating mechanism 3 is fixedly connected to the upper surface of base 1;
[0045] Distillation flask 4: This distillation flask 4 is fixedly connected to the right end face of the rotating mechanism 3;
[0046] Collection bottle 5: Collection bottle 5 is fixedly connected to the lower end face of rotating mechanism 3;
[0047] Limiting mechanism 6: Two limiting mechanisms 6 are provided, both of which are located on the outer surface of the collection bottle 5. The limiting mechanism 6 includes:
[0048] Main limiting block 610: The opposite side of the main limiting block 610 is in contact with the outer surface of the rotating mechanism 3;
[0049] Auxiliary limiting block 620: The opposite side of the auxiliary limiting block 620 is in contact with the outer surface of the collection bottle 5;
[0050] Sliding groove 630: The sliding groove 630 is formed on the upper surface of the auxiliary limiting block 620, and the inner wall of the sliding groove 630 is slidably connected to the lower surface of the main limiting block 610;
[0051] Telescopic component 640: Two telescopic components 640 are provided, and both telescopic components 640 are provided on the outer surface of the main limiting block 610 and the auxiliary limiting block 620;
[0052] Push component 650: Push component 650 is disposed on the outer surface of telescopic component 640.
[0053] refer to Figure 4 As shown, the telescopic assembly 640 includes:
[0054] Connecting rod 641: One end of the connecting rod 641 is fixedly connected to the opposite side of the main limiting block 610 and the auxiliary limiting block 620;
[0055] Telescopic spring 642: The telescopic spring 642 is sleeved on the outer surface of the connecting rod 641, and one end of the telescopic spring 642 is fixedly connected to the opposite side of the main limiting block 610 and the auxiliary limiting block 620.
[0056] The above scheme is adopted: the connecting rod 641 moves to the opposite side, and the connecting rod 641 can drive the main limiting block 610 and the auxiliary limiting block 620 to move closer to the rotating mechanism 3 and the collection bottle 5. After the main limiting block 610 is in contact with the outer surface of the rotating mechanism 3, it continues to move, so that the upper telescopic spring 642 generates elastic force and squeezes the main limiting block 610, so that the main limiting block 610 is in close contact with the outer surface of the rotating mechanism 3. Under the push of the telescopic spring 642, the auxiliary limiting block 620 moves closer to the collection bottle 5 through the sliding groove 630 and makes close contact, thus realizing the function of tightly connecting the lower surface of the rotating mechanism 3 with the upper end of the collection bottle 5. The opposite side of the main limiting block 610 and the auxiliary limiting block 620 is made of soft sponge material.
[0057] refer to Figure 1 As shown, the actuating component 650 includes:
[0058] Push plate 651: The inner wall of push plate 651 is slidably connected to the outer surface of connecting rod 641, and the opposite side of push plate 651 is fixedly connected to the opposite end of extension spring 642;
[0059] Slide rail 652: Slide rail 652 is formed on the upper surface of base 1, and the inner wall of slide rail 652 is slidably connected to the lower surface of push plate 651.
[0060] Using the above scheme: In order to move the connecting rod 641 to the opposite side, the push plate 651 moves along the slide rail 652 to the opposite side. The push plate 651 can drive the connecting rod 641 and also compress the telescopic spring 642.
[0061] refer to Figure 4 As shown, a space slot 7 is provided on the lower surface of the push plate 651. There are two space slots 7, and a stroke component 8 is provided between the two space slots 7.
[0062] The above scheme is adopted: the space slot 7 mainly serves to facilitate the connection of the components inside the space slot 7.
[0063] refer to Figure 2 As shown, there are two stroke components 8, and the two stroke components 8 include:
[0064] Stroke column 801: Both ends of stroke column 801 are rotatably connected to the inner wall of space groove 7 via rotating shafts;
[0065] Stroke block 802: The inner wall of stroke block 802 is slidably connected to the outer surface of stroke column 801.
[0066] Using the above scheme: In order to move the connecting plate to the opposite side, the stroke block 802 moves upward. The inner wall of the stroke block 802 can squeeze the stroke column 801, so that the stroke column 801 slides along the inner wall of the stroke block 802. The stroke column 801 can drive the push plate 651 to move to the opposite side.
[0067] refer to Figure 2 As shown, a connecting block 9 is provided on the lower surface of the stroke block 802. There are two connecting blocks 9, and the upper surfaces of the two connecting blocks 9 are fixedly connected to the lower surface of the stroke block 802. The connecting blocks 9 are "L" shaped.
[0068] Using the above scheme: Connecting block 9 mainly serves to connect stroke block 802.
[0069] refer to Figure 3 As shown, a support component 10 is provided on the opposite side of the connecting block 9. There are two support components 10, and the two support components 10 include:
[0070] Support plate 1001: The inner surface of support plate 1001 is in contact with the outer surface of collection bottle 5, and the outer surface of support plate 1001 is fixedly connected to the opposite side of connecting block 9;
[0071] Telescopic rod 1002: The upper end face of the telescopic rod 1002 is fixedly connected to the outer surface of the support plate 1001, and the lower end face of the telescopic rod 1002 is fixedly connected to the upper surface of the base 1;
[0072] Pressure relief spring 1003: Pressure relief spring 1003 is sleeved on the outer surface of telescopic rod 1002. The upper end face of pressure relief spring 1003 is fixedly connected to the outer surface of support plate 1001, and the lower end face of pressure relief spring 1003 is fixedly connected to the upper surface of base 1.
[0073] The above solution is adopted: In order to move the stroke block 802 to the opposite side, the rotating mechanism 3 is rotated upward, which can drive the collection bottle 5 to move upward, so that the collection bottle 5 no longer squeezes the support plate 1001. At this time, the pressure relief spring 1003 can release the elastic force and push the support plate 1001 to move upward. The support plate 1001 can drive the stroke block 802 to move upward. The inner wall of the support plate 1001 is made of soft sponge material.
[0074] The working principle of this utility model:
[0075] In use, first press down on the support plate 1001 to rotate and install the collection bottle 5 onto the lower surface of the rotating mechanism 3. Then, rotate the rotating mechanism 3 to allow the distillation flask 4 to enter the evaporator 2, and the collection bottle 5 moves upward. At this point, stop pressing the support plate 1001, and the telescopic spring 642 releases its elasticity, pushing the support plate 1001 upward and supporting the collection bottle 5. The upward movement of the support plate 1001 can drive the connecting block 9, which in turn drives the stroke block 802 upward. The inner wall of the stroke block 802 can press the stroke column 801, causing the stroke column 801 to slide along the inner wall of the stroke block 802. The stroke column 801 can then drive the push plate 651 to move along the slide rail 652. Moving to one side, the push plate 651 can drive the connecting rod 641, which in turn drives the main limiting block 610 and the auxiliary limiting block 620 to move closer to the rotating mechanism 3 and the collection bottle 5. When the main limiting block 610 is in contact with the outer surface of the rotating mechanism 3, the push plate 651 continues to move and can squeeze the upper telescopic spring 642, causing the telescopic spring 642 to generate elastic force. The telescopic spring 642 then squeezes the main limiting block 610, making the main limiting block 610 fit tightly against the outer surface of the rotating mechanism 3. Under the push of the telescopic spring 642, the auxiliary limiting block 620 moves closer to the collection bottle 5 through the sliding groove 630 and makes tight contact, thus achieving a tight connection between the collection bottle 5 and the rotating mechanism 3.
[0076] In summary, this rotary evaporator with a limiting function for extracting medicinal liquid, through its base 1, evaporator 2, rotating mechanism 3, distillation flask 4, collection flask 5, limiting mechanism 6, space groove 7, stroke assembly 8, connecting block 9, and support assembly 10, solves the problem that improper connection can cause the collection flask to fall due to increased internal gravity, resulting in spillage of the collected liquid inside the collection flask, which not only wastes materials but also greatly affects the extraction efficiency.
