[0035] The working principle of the present utility model:

[0036] During use, while inserting the connecting pipe 3 into the bottle mouth 2, insert the plug block 411 into the bottle mouth 2 and press the box body 412 downward at the same time. While pressing, the lower end of the chuck 422 contacts the bottle mouth 2, and the bottle mouth 2 squeezes the two chucks 422 to the left and right sides, causing the two chucks 422 to move to the left and right sides on the surface of the moving rod 421, and at the same time squeezing and compressing the push spring 423. When the box body 412 and the plug block 411 are pressed in place, the bottle mouth 2 will no longer squeeze the chuck 422. At this time, the push spring 423 will rebound and move the two chucks 422 together on the surface of the moving rod 421, so as to clamp the bottle mouth 2 and complete the sealing to prevent subsequent flushing of materials. When the bottle mouth 2 needs to be opened subsequently, by rotating the rotating cylinder 431 counterclockwise, while the rotating cylinder 431 rotates, it drives the extrusion disk 432 to rotate. While the extrusion disk 432 rotates, it squeezes the two chucks 422, causing the two chucks 422 to move to the left and right sides on the surface of the moving rod 421 to open, releasing the clamping of the bottle mouth 2, and then the box body 412 together with the plug block 411 can be pulled out upward. When the extrusion disk 432 rotates, the limiting rod 6 will cooperate with the limiting groove 433 to limit the rotation angle of the extrusion ring.

[0037] In summary: For the anti-flushing installation component at the bottle mouth of this rotary evaporation bottle, by setting the cooperation of the bottle body 1, the bottle mouth 2, the connecting pipe 3, the anti-flushing device 4, the cover mouth assembly 41, the plug block 411, the box body 412, the clamping assembly 42, the moving rod 421, the chuck 422, the push spring 423, the control assembly 43, the rotating cylinder 431, the extrusion disk 432, the limiting groove 433, the anti-slip pad 5 and the limiting rod 6, it solves the problem that in the existing rotary evaporation bottle during its use, its plug block is inserted into the bottle mouth to prevent material splashing, but in certain experiments, the solvent will boil violently or the pressure will suddenly change, resulting in a situation of pressure increase. In this way, it is very easy to cause the plug block to be flushed out, thus causing material splashing.
