DETAILED DESCRIPTION
[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0025] The utility model provides Figures 1 to 5 A rotary evaporator is shown, comprising:
[0026] A base 1, a support rod 2 is fixedly provided at the top of the base 1, an evaporator body 3 is fixedly provided at the front end of the support rod 2, a condenser 4 is connected to the fixed end of the evaporator body 3, a feed valve 5 is connected to the feed end of the condenser 4, a collecting bottle 6 is connected to the liquid outlet end of the condenser 4, and a rotating bottle 8 is threadedly connected to the rotating end of the evaporator body 3;
[0027] The protection frame 7, the rotating bottle 8 is arranged inside the protection frame 7, one end of the rotating bottle 8 passes through the inclined surface on the protection frame 7 and is rotatably connected with the inclined surface through a sealed bearing;
[0028] A sealing connection frame 9 is fixedly arranged at the bottom end of the protection frame 7. A sealing airbag cushion 13 is fixedly arranged inside the sealing connection frame 9. A ventilation pipe 14 connected with the inside of the sealing airbag cushion 13 is fixedly arranged at the outer end of the sealing airbag cushion 13. One end of the ventilation pipe 14 passes through the sealing connection frame 9 and extends to the outer end of the sealing connection frame 9. A ventilation valve 15 is fixedly arranged on the ventilation pipe 14. A heating component is arranged at the bottom of the sealing connection frame 9.
[0029] The heating assembly includes a heating frame 10 arranged at the bottom of the sealing connection frame 9, a heating plate 11 is arranged inside the heating frame 10, a heating pot 12 is arranged on the heating plate 11, the top end of the heating pot 12 extends to the top of the heating frame 10, and the top end of the heating pot 12 extends into the sealed airbag cushion 13 on the inner wall of the sealing connection frame 9.
[0030] A support plate 16 is provided at the top of the base 1, and two rotating threaded sleeves 17 are rotatably connected to the top of the support plate 16. Two threaded rods 18 are fixedly provided at the bottom of the heating frame 10. The bottom ends of the threaded rods 18 extend into the interior of the rotating threaded sleeve 17 and are threadedly connected to the rotating threaded sleeve 17. A turning handle 19 is fixedly provided at the outer end of the rotating threaded sleeve 17.
[0031] The supporting and fixing structure of the condenser 4 and the collecting bottle 6 is the prior art and is not shown here. First, the evaporator body 3, the condenser 4, the feed valve 5 and the collecting bottle 6 are fixed, and then the end of the rotating bottle 8 is aligned with the rotating end on the base 1, and the rotating bottle 8 is rotated to connect the rotating bottle 8 with the rotating end of the base 1. Then, water is added to the inside of the heating pot 12, and then the heating frame 10 and the heating pot 12 are placed on the bottom of the protective frame 7 and the sealing connection frame 9, and the turning handle 19 is turned. The turning handle 19 drives the rotating threaded sleeve 17 to rotate. Since the rotating threaded sleeve 17 is threadedly connected to the threaded rod 18, the threaded rod 1 As the rotating threaded sleeve 17 rotates and moves upward, the threaded rod 18 drives the heating frame 10 and the heating pot 12 to move upward, and the top of the heating pot 12 is inserted into the sealed airbag cushion 13 on the inner wall of the sealed connection frame 9, and the air is inflated into the sealed airbag cushion 13 through the vent pipe 14, so that the connection between the heating pot 12 and the sealed connection frame 9 can be sealed.

The use effect is good and the practicability is strong. This embodiment specifically solves the problem that when the rotary evaporator in the prior art is actually used, there is no protective structure on the heating pot, so the steam generated in the heating pot is easy to escape to the outside, which makes the temperature around the rotating bottle uneven, and the loss of steam also causes waste of heat, resulting in insufficient use effect.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
