[0030] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0031] Figure 1 Schematic diagram of the structure of a rotary evaporator provided in an embodiment of the present disclosure. Figure 1 The rotary evaporator includes: a platform 101, a heating device 102, a rotating shaft 103, a tray 104, a gravity sensor 105 and a display terminal 106.

[0032] Among them, the tray 104 is located in the heating device 102; the platform 101 has a built-in motor (not shown in the figure), one end of the rotating shaft 103 is connected to the motor, and the other end of the rotating shaft 103 is connected to the tray 104 in the heating device 102; the gravity sensor 105 is fixed in the middle of the rotating shaft 103 and is located between the platform 101 and the heating device 102; the display terminal 106 is electrically connected to the gravity sensor 105.

[0033] In the disclosed embodiment, the motor in the platform 101 can provide rotational power for the rotating shaft 103, thereby increasing the evaporation surface of the sample in the container in the tray 104. The heating device 102 provides thermal energy for the sample in the container in the tray 104, thereby achieving evaporation.

[0034] In the embodiment of the present disclosure, a gravity sensor 105 is disposed in the middle of the rotating shaft 103. The gravity sensor 105 detects a gravity signal and provides the gravity signal to the display terminal 106, so that the display terminal 106 displays the evaporation progress based on the gravity signal, thereby avoiding energy waste caused by continuing evaporation when evaporation is completed. In addition, based on the evaporation progress provided by the display terminal 106, the rotation speed and heating temperature can also be adjusted during the evaporation process, thereby improving the evaporation efficiency.

[0035] In the embodiment of the present disclosure, although the gravity sensor 105 does not directly bear the weight of the sample in the heating device 102, the gravity sensor 105 can still sense the change in gravity, and the change in sample weight will cause the torque of the rotating shaft 103 to change, so that the gravity sensor 105 can output a gravity signal based on the gravity change and the torque change.

[0036] In the embodiment of the present disclosure, the platform 101 may be a metal platform, which has high mechanical strength.

[0037] like Figure 1 As shown, in some examples, the platform 101 may be a rectangular parallelepiped structure.

[0038] In other examples, the platform 101 may also be a structure of other shapes, such as a cylinder.

[0039] In the disclosed embodiment, the heating device 102 may be a sealed box with a built-in heating component. The heating device 102 is supported by other supporting structures and is rotatably sealed and assembled with the rotating shaft 103 .

[0040] like Figure 1 As shown, in some examples, the heating device 102 may be a rectangular parallelepiped structure.

[0041] In some examples, the heating device 102 may be a table-like structure, that is, the heating device 102 is open in a direction from close to to far away from the platform 101 .

[0042] In other examples, the heating device 102 may also be in other shapes, such as a cylindrical shape.

[0043] In the embodiment of the present disclosure, the heating device 102 has a vacuum valve and an air release valve (not shown in the figure) as an inlet and outlet passage of the heating device 102 .

[0044] In other embodiments, the heating device 102 may also have other ways of serving as the entry and exit channels.

[0045] In the embodiment of the present disclosure, the heating device 102 may be a detachable structure, so as to enable the placement and removal of containers and samples.

[0046] In the disclosed embodiment, the heating device 102 may also have a built-in temperature sensor, so as to monitor the sample evaporation environment temperature.

[0047] In the embodiment of the present disclosure, the initial temperature of the heating device 102 may be room temperature.

[0048] Exemplarily, the initial temperature of the heating device 102 is 25 degrees.

[0049] In the embodiment of the present disclosure, the rotating shaft 103 may be a metal rotating shaft, which has high mechanical strength and can ensure that the gravity sensor 105 can detect gravity changes.

[0050] In the embodiment of the present disclosure, driven by the motor, the rotation speed of the rotating shaft 103 may be 300 to 800 revolutions per minute.

[0051] For example, the initial rotation speed of the rotating shaft 103 may be 500 revolutions per minute.

[0052] In the disclosed embodiment, the tray 104 is a metal tray, which has high mechanical strength.

[0053] In the embodiment of the present disclosure, the tray 104 may be a bowl-shaped structure, and a plurality of holes are provided on the tray 104 for placing containers containing samples.

[0054] Figure 2 FIG. 1 is a top view of a tray provided in an embodiment of the present disclosure. Figure 2 As shown, the bottom 202 of the tray is a plane, the side wall of the tray 104 is a bowl-shaped surface, and a plurality of holes 201 are located on the side wall of the tray 104 .

[0055] In the embodiment of the present disclosure, the plurality of holes 201 may include at least two different diameters, thereby providing containers of different sizes.

[0056] The tray 104 can be connected to the bottom 202 of the tray. Figure 1 The rotating shafts 103 are shown connected, for example, by bolting or welding.

[0057] In the disclosed embodiment, the container may be a test tube, and the experimenter may fix test tubes of different sizes in the holes 201 of the corresponding diameters according to the sizes of the test tubes. During the rotary evaporation process, the test tube of the sample is not airtight, which may allow the water in the sample to evaporate and become water vapor. After the water vapor leaves the test tube, it will be drawn out by the vacuum valve; when the pressure in the test tube is too high, the air release valve is opened to restore the pressure in the test tube to a normal state; during the rotary evaporation process, the water evaporates and leaves the sample test tube, the gravity changes, and the gravity signal output by the gravity sensor 105 changes.

[0058] Figure 3 FIG. 1 is a schematic diagram of the assembly of the gravity sensor provided by the embodiment of the present disclosure. Figure 3 As shown, the gravity sensor 105 can be directly connected to the rotating shaft 103, for example, by gluing, welding or the like.

[0059] In other implementations, the gravity sensor 105 may also be connected to the rotating shaft 103 via a connection structure, such as a bolt connection, or a lock or other structure connection.

[0060] In the embodiment of the present disclosure, the display terminal 106 may include a display screen 160 and a controller 161. The controller 161 is responsible for acquiring the signal of the gravity sensor 105 and outputting the progress information to the display screen 160 for display.

[0061] Figure 4 1 is a schematic diagram of the structure of the display terminal provided by the embodiment of the present disclosure. The controller 161 may include a data processing and analysis module 162 , an adaptive module 163 and a user interface configuration module 164 .

[0062] The data processing and analysis module 162 is used to obtain the signal of the gravity sensor 105 and generate evaporation progress information and output it to the display screen 160 for display.

[0063] The data processing and analysis module 162 may pre-store the corresponding relationship between the gravity signal and the evaporation progress, so that when the gravity signal is received, the evaporation progress corresponding to the gravity signal may be output.

[0064] The adaptive module 163 may be connected to the motor and the heating device 102 to adaptively control the speed of the motor and the temperature of the heating device 102 based on the evaporation progress.

[0065] The user interface configuration module 164 is used to configure the display interface of the display screen 160. The user interface configuration module 164 can also provide a control interface for the motor and heating device 102, so as to realize manual control of the motor and heating device 102.

[0066] It should be noted that the functions performed by the above modules are all conventional software algorithm functions, which will not be elaborated in the embodiments of the present disclosure.

[0067] Optionally, the rotary evaporator may further include a rotation speed sensor, which is fixed in the middle of the rotating shaft 103 and located between the platform 101 and the heating device 102; the display terminal 106 is electrically connected to the rotation speed sensor. The rotation speed sensor is used to measure the rotation speed, and the display terminal 106 can also be used to display the rotation speed.
