The output end of the third driving member 12 is connected and fixed to one end of the third transmission member 13. The other end of the third transmission member 13 passes through the mounting seat 11 to be connected and fixed to the container seat 20.

[0057] Please refer to Figure 1 、 Figure 3 and Figure 4 The sealing assembly 30 includes a sealing structure 32 and a first moving mechanism 33 . The sealing structure 32 is connected to the first moving mechanism 33 . The first moving mechanism 33 is used to drive the sealing structure 32 to move along a first direction.

[0058] Optionally, the first moving mechanism 33 is mounted on the aforementioned base 50, and the sealing structure 32 is connected to a side of the first moving mechanism 33 facing the container seat 20. The first moving mechanism 33 drives the sealing structure 32 to move in the first direction, so that the sealing structure 32 has the aforementioned third position and the aforementioned fourth position. When the sealing structure 32 is in the third position, the sealing structure 32 and the container 200 or the container seat 20 are spaced apart from each other in the first direction.

[0060] Exemplarily, when container 200 is placed on container holder 20, the opening of container 200 faces sealing structure 32. To improve the ability of exhaust channel 31 to discharge gas generated within container 200, exhaust channel 31 extends along a first direction, and the inner wall surface of exhaust channel 31 is a smooth curved surface or a flat surface.

[0063] Optionally, the seal 322 and the mounting member 321 can be rotatably connected via a structure such as a rotating shaft, a sliding sleeve, or a latch, so that when the seal 322 rotates with the container 200, the seal 322 and the mounting member 321 rotate relative to each other, thereby fixing the first movable mechanism 33 and the mounting member 321 in the rotational direction of the seal 322. This avoids the need for additional rotating structures on the first movable mechanism 33 or the mounting member 321 to prevent motion interference, thereby simplifying the assembly of the first movable mechanism 33 and the mounting member 321. Optionally, the exhaust passage 31 passes through the seal 322 in the first direction to improve the exhaust performance of the exhaust passage 31.

Optionally, the sealing gasket 3222 can be made of a material with good heat resistance, stable chemical properties and elastic deformation, specifically rubber, silicone and nylon, etc. The sealing gasket 3222 can elastically abut the top surface of the opening of the container 200 to close the opening of the container 200.

The sealing gasket 3222 is connected to one end of the rotating shaft 3221 facing the container seat 20. The exhaust channel 31 passes through the rotating shaft 3221 and the sealing gasket 3222. The sealing gasket 3222 is used to seal the opening of the container 200, so that the sealing member 322 can seal the opening of the container 200 through the sealing gasket 3222, preventing the rotating shaft 3221 and other structures with greater hardness from contacting the container 200, thereby avoiding damage to the container 200. At the same time, the mounting member 321 is provided with a bearing 3211 and a bearing seat 3212. The bearing 3211 is fixed in the bearing seat 3212. The rotating shaft 3221 is passed through the bearing 3211 and is rotatably connected to the bearing 3211, so that the sealing member 322 can be rotatably connected to the mounting member 321 through the bearing seat 3212 and the bearing 3211, thereby reducing wear between the sealing member 322 and the mounting member 321.

[0071] Please refer to Figure 1 、 Figure 3 and Figure 4 The mounting member 321 also includes a sealing sleeve 3214 and a limiting member 3215. The sealing sleeve 3214 is fixed in the bearing seat 3212 and is sleeved on the end of the rotating shaft 3221 away from the sealing gasket 3222. The sealing sleeve 3214 is sealedly connected to the rotating shaft 3221 and the bearing seat 3212. The limiting member 3215 is located between the bearing 3211 and the sealing sleeve 3214. The limiting member 3215 is used to limit the bearing 3211 and the sealing sleeve 3214 in the axial direction of the rotating shaft 3221.

[0072] Optionally, the rotating shaft 3221 is passed through the bearing seat 3212 so that the opening of the exhaust channel 31 at one end away from the container seat 20 protrudes from the bearing seat 3212. In order to prevent the gas in the exhaust channel 31 from leaking through the gap between the rotating shaft 3221 and the bearing seat 3212, or to prevent outside air from entering through the gap between the rotating shaft 3221 and the bearing seat 3212, the sealing sleeve 3214 is sealed and connected to the rotating shaft 3221 and the bearing seat 3212.

[0073] Optionally, the limiting member 3215 is fixedly connected to the rotating shaft 3221 , and the limiting member 3215 is rotatably connected to the bearing 3211 , the sealing bushing 3214 and the bearing seat 3212 . Optionally, the bearing seat 3212 encloses a first cavity 3216, a second cavity 3217 and a third cavity 3218 which are connected in sequence in the first direction, the bearing 3211 is accommodated in the first cavity 3216, the limit member 3215 is accommodated in the second cavity 3217, and the sealing sleeve 3214 is accommodated in the third cavity 3218, wherein a third protrusion structure 3219 is provided at the junction of the first cavity 3216 and the second cavity 3217, and the surface of the third protrusion structure 3219 facing the first cavity 3216 is connected and fixed to the bearing 3211, so that the bearing 3211 and the other side of the bearing seat 3212 in the first direction are relatively fixed, and the surface of the third protrusion structure 3219 facing the second cavity 3217 contacts the limit member 3215, so that the limit member 3215 and the rotating shaft 3221 are relatively fixed to the bearing seat 3212 in the first direction.

[0074] Optionally, lubricating oil or engine oil is added between the sealing bushing 3214, the mounting seat 11, the limiting member 3215, the bearing 3211 and the rotating shaft 3221 to reduce wear and improve air tightness.

[0075] By setting a sealing bushing 3214, the sealing bushing 3214 is fixed in the bearing seat 3212 and is sleeved on the end of the rotating shaft 3221 away from the sealing gasket 3222. The sealing bushing 3214 is sealed with the rotating shaft 3221 and the bearing seat 3212, so that the gas in the exhaust channel 31 will not leak from the gap between the rotating shaft 3221 and the bearing seat 3212, thereby avoiding damage to the rotary evaporation device 100 caused by gas leakage and adverse effects on the experimental structure caused by gas leakage. At the same time, a limiter 3215 is set between the bearing 3211 and the sealing bushing 3214. The limiter 3215 is used to limit the bearing 3211 and the sealing bushing 3214 in the axial direction of the rotating shaft 3221, so that the sealing bushing 3214 will not be displaced in the first direction due to gravity and the rotation of the rotating shaft 3221. At the same time, it prevents the bearing 3211 from causing wear on the sealing bushing 3214 when the sealing bushing 3214 and the bearing 3211 rotate relative to each other.

[0076] Please refer to Figure 1 、 Figure 3 and Figure 4The first moving mechanism 33 includes a first driving member 331, a first transmission member 332 and a first guide member 333. The first guide member 333 is arranged along the first direction. The first transmission member 332 is transmission-connected to the output end of the first driving member 331. The first transmission member 332 is movably connected to the first guide member 333. The first transmission member 332 is connected to the sealing structure 32. The first driving member 331 is used to drive the first transmission member 332 and the sealing structure 32 to move along the first guide member 333.

[0077] Optionally, one end of the first guide member 333 is connected to the aforementioned base 50, and the other end is connected to the fixing plate 336, and the first driving member 331 is connected to the fixing plate 336. Optionally, there are multiple first guide members 333, and the multiple first guide members 333 are spaced apart and parallel to each other, and the first transmission member 332 is movably connected to the multiple first guide members 333.

[0078] Exemplarily, the first guide member 333 is a columnar structure, the first transmission member 332 is fixedly connected to the sleeve 334, the sleeve 334 is sleeved on the first guide member 333 and is slidably connected to the first guide member 333, and the first driving member 331 drives the first transmission member 332 and the sleeve 334 to move synchronously along the first guide member 333. Optionally, the first guide member 333 may include a guide rod and a bearing slidably arranged on the guide rod, and the first transmission member 332 is connected to the bearing. The first transmission member 332 may be a block structure or a plate structure, without limitation. Optionally, the first transmission member 332 and the first guide member 333 may also be movably connected by structures such as a gear rack pair and a slideway slider pair, without limitation.

[0079] Exemplarily, the first driving member 331 can be a motor, an oil cylinder, an air cylinder, etc., without limitation. The first driving member 331 has a driving shaft 335, and the driving shaft 335 is connected to the first transmission member 332. When the first driving member 331 is in operation, the driving shaft 335 can perform linear motion or rotational motion. Exemplarily, the first driving member 331 is a linear motor or a screw motor, which converts the rotational motion of the driving shaft 335 into linear motion along the first direction through a structure such as a screw-nut pair, thereby driving the first transmission member 332 to move along the first direction. Optionally, when the first driving member 331 is an oil cylinder or an air cylinder, the driving shaft 335 is a piston rod, which can be extended and retracted along the first direction under the action of pressure changes to drive the first transmission member 332 to move along the first direction.

[0080] By setting up the first moving mechanism 33 including the first driving member 331, the first transmission member 332 and the first guide member 333, the first guide member 333 is set along the first direction, the first transmission member 332 is transmission-connected to the output end of the first driving member 331, the first transmission member 332 is movably connected to the first guide member 333, the first transmission member 332 is connected to the sealing structure 32, and the first driving member 331 is used to drive the first transmission member 332 and the sealing structure 32 to move along the first guide member 333, so that the sealing structure 32 can move along the first direction under the drive of the first driving member 331 and under the restriction of the first transmission member 332 and the first guide member 333, and will not move in other directions, thereby ensuring that the sealing structure 32 can be accurately connected to the opening of the container 200.

[0081] Please refer to Figure 1 、 Figure 3 and Figure 4 The sealing assembly 30 further includes a buffer mechanism 323 disposed between the first transmission member 332 and the sealing structure 32. The buffer mechanism 323 is configured to cause the sealing structure 32 to move in a first direction relative to the first transmission member 332. The buffer mechanism 323 includes a guide post 3231 and an elastic member 3232. One of the first transmission member 332 and the sealing structure 32 is slidably connected to one end of the guide post 3231, while the other is fixedly connected to the other end of the guide post 3231. The elastic member 3232 is sleeved on the guide post 3231. One end of the elastic member 3232 abuts the first transmission member 332, and the other end abuts the sealing structure 32.

[0082] Specifically, the elastic member 3232 can be in a compressed state both when the sealing structure 32 is not sealedly connected to the opening of the container 200 and when the sealing structure 32 is sealedly connected to the opening of the container 200. The compression of the elastic member 3232 when the sealing structure 32 is sealedly connected to the opening of the container 200 is greater than the compression when the sealing structure 32 is not sealedly connected to the opening of the container 200. The elastic member 3232 provides a preload force for the sealing structure 32 to prevent the sealing structure 32 from separating from the container 200 even when the first moving mechanism 33 is displaced or vibrated, thereby ensuring the sealing performance of the sealing structure 32 with respect to the container 200. The elastic member 3232 can be a compression spring, a rubber sleeve, a metal spring, etc., without limitation.

[0083] Illustratively, one end of the guide post 3231 passes through the first transmission member 332 and is slidably connected thereto, while the other end of the wire post is fixedly connected to the mounting member 321 of the sealing structure 32. Optionally, a fourth protrusion 3233 is provided on the end of the guide post 3231 located on the first transmission member 332 facing away from the sealing structure 32. The fourth protrusion 3233 protrudes from the outer circumferential surface of the guide post 3231. The fourth protrusion 3233 abuts the first transmission member 332 in a first direction, allowing the sealing structure 32 to be suspended on the first transmission member 332 via the buffer mechanism 323.

[0084] By setting a buffer mechanism 323, the buffer mechanism 323 is arranged between the first transmission member 332 and the sealing structure 32, and the buffer mechanism 323 is used to make the sealing structure 32 move relative to the first transmission member 332 along the first direction. The buffer mechanism 323 includes a guide column 3231 and an elastic member 3232. One of the first transmission member 332 and the sealing structure 32 is slidingly connected to one end of the guide column 3231, and the other is fixedly connected to the other end of the guide column 3231. The elastic member 3232 is sleeved on the guide column 3231, and one end of the elastic member 3232 abuts against the first transmission member 332, and the other end abuts against the sealing structure 32, so that the sealing structure 32 can always be sealed and connected to the opening of the container 200 under the pre-tightening force of the elastic member 3232, and is not easily separated due to the displacement and vibration of the first moving mechanism 33.

[0085] Please refer to Figure 1 and Figure 5 The heating assembly 40 includes a heating element 41 and a second moving mechanism 42. The heating element 41 is connected to the second moving mechanism 42. The second moving mechanism 42 is used to drive the heating element 41 to move along the second direction so that the heating element 41 has a first position and a second position.

[0086] Optionally, respective implementations of the first direction and the second direction have been described in the aforementioned specific implementations, which will not be repeated here for reference only.

[0087] Optionally, the second moving mechanism 42 includes a first mounting plate 421, a second driving member 422, a second transmission member 423 and a second guide member 424, the second guide member 424 extends along the second direction, the first mounting plate 421 is connected to the aforementioned base 50, the second driving member 422 and the second guide member 424 are both connected to the side of the first mounting plate 421 facing the container seat 20, the second driving member 422 is transmission-connected to the second transmission member 423, the second transmission member 423 is movably connected to the second guide member 424, the heating member 41 is connected to the side of the second transmission member 423 facing the container seat 20, the second driving member 422 is used to drive the second transmission member 423 to move along the second direction, thereby driving the heating member 41 to move along the second direction.

[0088] Optionally, the structure of the second driving member 422 is similar to that of the first driving member 331, and is hereby referred to without further explanation. Optionally, the second guide member 424 and the second transmission member 423 can be movably connected by a sliding bar slider pair, a sliding groove slider pair, a gear rack pair, etc., without limitation.

[0089] By setting the heating assembly 40 to include a heating element 41 and a second moving mechanism 42, the heating element 41 is connected to the second moving mechanism 42, and the second moving mechanism 42 is used to drive the heating element 41 to move along the second direction so that the heating element 41 has a first position and a second position. When the heating element 41 is in the first position, the heating element 41 and the container seat 20 are spaced apart from each other in the second direction. When the heating element 41 is in the second position, the heating element 41 is used to heat the container 200, so that the heating element 41 can heat the container 200 when it is in the second position. When the heating element 41 does not need to heat the container 200, it can move from the second position to the first position under the drive of the second moving mechanism 42, which is convenient for other operations on the container 200, thereby improving the practicality of the rotary evaporation device 100.

[0090] Please refer to Figure 1 、 Figure 5 and Figure 6 The rotary evaporation device 100 further includes a heat-insulating assembly 60, which includes a first heat-insulating member 61 and a second heat-insulating member 62. The first heat-insulating member 61 is disposed around the periphery of the container seat 20 and has a take-in / take-out opening 611 and a top opening 612. The take-in / take-out opening 611 is used to take the container 200 onto the container seat 20, and the top opening 612 is used to allow the sealing assembly 30 to enter. The second heat-insulating member 62 is connected to the second moving mechanism 42. The heating member 41 is disposed on the side of the second heat-insulating member 62 facing the container seat 20. The second moving mechanism 42 is used to drive the second heat-insulating member 62 to move in a second direction to close or open the take-in / take-out opening 611.

[0091] Optionally, the heating element 41 may also be arranged on the surface of the first thermal insulation member 61 facing the container seat 20. Optionally, the thermal insulation component 60 further includes a first fixing member 63 and a second fixing member 64, the first fixing member 63 and the second fixing member 64 are respectively connected to the two opposite end faces of the first thermal insulation member 61, and there are two first guide members 333, and the two first guide members 333 are respectively connected and fixed to the first fixing member 63 and the second fixing member 64. Optionally, the first fixing member 63 and the second fixing member 64 can be an integrated structure with the first thermal insulation member 61, or can be detachably connected by means of snap connection, screw connection and riveting, without limitation. The heating element 41 can be an infrared heating tube, an electric heating tube, a heating rod, etc., without limitation.

[0092] Optionally, the rotary evaporation device 100 further includes a controller 70 and a detection member 71. The detection member 71 is electrically connected to the controller 70, and the controller 70 is also electrically connected to the heating member 41. The controller 70 is installed at the end of the sealing component 30 away from the container seat 20, that is, the controller 70 is installed at the top of the rotary evaporation device 100. The detection member 71 is provided on the surface of the first thermal insulation member 61 facing the container seat 20 or the surface of the second thermal insulation member 62 facing the container seat 20. The detection member 71 is used to detect the temperature of the container 200. The controller 70 can control the heating value and the start and stop of the operation of the heating member 41 according to the detection member 71. Optionally, the controller 70 is also electrically connected to the rotating component 10, the first moving mechanism 33 and the second moving mechanism 42. The controller 70 can control the working state of the rotating component 10, the first moving mechanism 33 and the second moving mechanism 42.

[0093] Optionally, the rotary evaporation device 100 also includes a cable restraint 72, which is installed on the base 50 and is located on one side of the heating component 40 in the left and right direction X of the rotary evaporation device 100. The cable restraint 72 is used to accommodate the cables between the controller 70, the detection component 71, the rotating component 10, the sealing component 30 and the heating component 40.

[0094] By setting up the insulation component 60, the insulation component 60 includes a first insulation member 61 and a second insulation member 62. The first insulation member 61 is arranged around the outer periphery of the container seat 20 and has a take-in and put-out port 611 and a top opening 612. The take-in and put-out port 611 is used to take-in and put-out the container 200 on the container seat 20, and the top opening 612 is used for the sealing component 30 to enter. The second insulation member 62 is connected to the second moving mechanism 42. The heating member 41 is arranged on the side of the second insulation member 62 facing the container seat 20. The second moving mechanism 42 is used to drive the second insulation member 62 to move along the second direction to close or open the take-in and put-out port 611, thereby reducing the temperature dissipation when the heating member 41 heats the container 200, and improving the heating effect of the rotary evaporation device 100. At the same time, the second insulation member 62 can close or open the take-in and put-out port 611 under the drive of the second moving mechanism 42, which is convenient for taking and putting the container 200 and improves the practicality of the rotary evaporation device 100.

[0095] Please refer to Figure 1 , the first direction is the same as the second direction, and both the first direction and the second direction are vertical directions; or, the first direction is perpendicular to the second direction, the first direction is a vertical direction, and the second direction is a horizontal direction.

[0096] The first direction is the same as the second direction, and both the first direction and the second direction are vertical directions, that is, the aforementioned first moving mechanism 33 drives the sealing component 30 to move up and down along the height direction Z of the rotary evaporation device 100, and the aforementioned second moving mechanism 42 drives the heating component 40 to move up and down along the height direction Z of the rotary evaporation device 100, thereby reducing the space occupied by the rotary evaporation device 100 in the horizontal direction. The control procedures of the first moving mechanism 33 and the second moving mechanism 42 are also similar, which is convenient for control.

[0097] Alternatively, the first direction is perpendicular to the second direction, the first direction is the vertical direction, and the second direction is the horizontal direction. At this time, the second direction can be the front-to-back direction Y of the rotary evaporation device 100 or the left-to-right direction X of the rotary evaporation device 100. Since a rotating component 10 is also provided under the container seat 20, when the second moving mechanism 42 drives the heating component 40 to move downward in the vertical direction, there is a risk that the residual heat of the heating element 41 can easily damage the rotating component 10.

[0098] Both of the above embodiments can achieve the sealing assembly 30 sealing or unsealing the opening of the container 200 and the heating assembly 40 moving closer to or further away from the container seat 20. Different embodiments can be adopted to assemble the rotary evaporation device 100 according to the specific installation environment. For example, this application uses the first direction and the second direction as the same, and both the first direction and the second direction are vertical directions as an example, wherein the rotating assembly 10, the container seat 20, and the first moving mechanism 33 are arranged in sequence in the first direction.

[0099] By setting the first direction and the second direction to be the same, and both the first direction and the second direction are vertical directions, or setting the first direction and the second direction to be perpendicular, the first direction is a vertical direction, and the second direction is a horizontal direction, the rotary evaporation device 100 can be assembled in different ways according to the specific installation environment, thereby improving the practicality of the rotary evaporation device 100.

[0100] Please refer to Figure 1 The rotary evaporation device 100 further includes a gas collecting assembly 80 , which is connected to the sealing assembly 30 and communicates with the exhaust channel 31 . The gas collecting assembly 80 is used to collect the volatilized gas in the container 200 .

[0101] Optionally, a gas collection assembly 80 is connected to the end of the sealing assembly 30 away from the heating assembly 40 to prevent damage to the gas collection assembly 80 due to high temperatures. Optionally, the gas collection assembly 80 can be an active gas collector or a passive gas collector. An active gas collector typically actively extracts gas from the exhaust passage 31 using a device such as a vacuum pump to prevent gas condensation in the exhaust passage 31 and the pipeline. A passive gas collector typically exhausts gas from the exhaust passage 31 through the pressure difference between the inside and outside atmospheres, which has the advantages of energy saving and low noise.

[0102] By setting up a gas collection component 80, the gas collection component 80 is connected to the sealing component 30 and communicated with the exhaust channel 31. The gas collection component 80 is used to collect the volatilized gas in the container 200, so that the volatilized gas in the container 200 can be collected into the gas collection component 80 through the exhaust channel 31, preventing the gas from condensing and reflowing in the exhaust channel 31. At the same time, the gas can be recycled after condensing in the gas collection component 80 to reduce the experimental cost.

[0103] Please refer to Figure 1 、 Figure 3 and Figure 4 The gas collection assembly 80 includes an adapter 81 and an exhaust pipe 82. The adapter 81 is provided with a adapter channel 811. One end of the adapter 81 is sealedly connected to the sealing assembly 30, and the other end of the adapter 81 is sealedly connected to the exhaust pipe 82. The adapter channel 811 connects the exhaust channel 31 and the exhaust pipe 82.

[0104] Optionally, the adapter 81 is connected to the end of the bearing seat 3212 that is away from the container seat 20 in the front-to-back direction Y of the rotary evaporator 100, and protrudes from the side of the bearing seat 3212 that is away from the heating assembly 40. The exhaust pipe 82 is connected to the end of the adapter 81 that is away from the bearing seat 3212 to prevent the heating assembly 40 from damaging the exhaust pipe 82. Optionally, the adapter 81 and the bearing seat 3212 are an integrated structure. The adapter 81, the bearing seat 3212, and the sealing bushing 3214 enclose a cavity that connects the adapter channel 811 and the exhaust channel 31 to improve airtightness.

[0105] By setting up an adapter 81 and an exhaust pipe 82, the adapter 81 is provided with a adapter channel 811, one end of the adapter 81 is sealedly connected to the sealing assembly 30, and the other end of the adapter 81 is sealedly connected to the exhaust pipe 82. The adapter channel 811 connects the exhaust channel 31 and the exhaust pipe 82, so that the exhaust pipe 82 is connected to the exhaust channel 31 through the adapter 81, thereby improving the connection stability of the exhaust pipe 82 and the sealing structure 32.

[0106] Please refer to Figure 1The exhaust pipe 82 includes a first pipe 821 and a second pipe 822 that are connected. One end of the first pipe 821 is sealed and connected to the adapter 81 and is connected to the transfer channel 811. The other end of the first pipe 821 is sealed and connected to the second pipe 822. The first pipe 821 is retractable. When the sealing assembly 30 moves along the first direction, the first pipe 821 moves relative to the second pipe 822.

[0107] Optionally, the first pipe 821 can be a pipe that is resistant to high temperatures, chemically stable, and flexibly deformable, specifically a metal bellows, a plastic hose, a rubber hose, etc., without limitation.

[0108] Optionally, the first pipe 821 and the second pipe 822 are movably connected. Specifically, the first pipe 821 is sleeved within the second pipe 822, or the second pipe 822 is sleeved within the first pipe 821. When the sealing assembly 30 moves in the first direction, the first pipe 821 slides relative to the second pipe 822. This arrangement improves the flexibility and adaptability of the device. The first pipe 821 can be made of a metal pipe to extend its service life. For example, the first pipe 821 can be a retractable stainless steel pipe.

[0109] By setting the exhaust pipe 82 to include a first pipe 821 and a second pipe 822 that are connected, one end of the first pipe 821 is sealed and connected to the adapter 81 and is connected to the transfer channel 811, and the other end of the first pipe 821 is sealed and connected to the second pipe 822. The first pipe 821 is retractable. When the sealing assembly 30 moves along the first direction, the first pipe 821 moves relative to the second pipe 822, so that when the sealing assembly 30 moves, the exhaust pipe 82 will not fold or twist when it moves driven by the sealing assembly 30, thereby reducing the risk of blockage or damage to the exhaust pipe 82.

[0110] Please refer to Figure 1 The rotary evaporation device 100 also includes a condensing mechanism, which is sealedly connected to the exhaust pipe 82, and the condensing mechanism is used to cool and recover the gas volatilized in the container 200; or, the rotary evaporation device 100 also includes a vacuuming mechanism, which is sealedly connected to the exhaust pipe 82, and the vacuuming mechanism is used to vacuum the container 200; or, the rotary evaporation device 100 also includes a condensing mechanism and a vacuuming mechanism, and the condensing mechanism is sealedly connected to the exhaust pipe 82 and the vacuuming mechanism respectively, and the condensing mechanism is used to cool and recover the gas volatilized in the container 200, and the vacuuming mechanism is used to vacuum the container 200.

[0111] Optionally, the condensing mechanism can be a water-cooled condenser or an air-cooled condenser, etc., without limitation. The water-cooled condenser realizes cooling and recovery of the gas through heat exchange between the refrigerant and the gas, and the air-cooled condenser usually realizes cooling and recovery of the gas by heat exchange between the gas and the air through structures such as fans and heat dissipation fins.

[0112] Optionally, the vacuum pumping mechanism may be a reciprocating vacuum pump or an oil-sealed mechanical pump, etc., without limitation. The reciprocating vacuum pump extracts the gas in the exhaust pipe 82 through the reciprocating motion of the piston, thereby achieving a vacuum state. The oil-sealed mechanical pump uses an oil seal to prevent gas backflow and extracts the gas through a rotating rotor.

[0113] By setting up a condensing mechanism and / or a vacuuming mechanism and sealingly connecting it to the exhaust pipe 82, the condensing mechanism is used to cool and recover the gas volatilized in the container 200, and the vacuuming mechanism is used to vacuum the container 200, so that a vacuum environment is formed in the container 200, and the volatilized gas can be quickly discharged through the exhaust pipe 82, preventing the gas from condensing and flowing back into the container 200, thereby improving the working efficiency of the rotary evaporation device 100.
