[0020] See also Figure 1-Figure 3 A magnetic stirrer for preventing a stirring liquid from splashing comprises a magnetic stirrer 1, a pressing plate 18 is placed above the magnetic stirrer 1, a first handle 13 is fixedly provided on the top of the pressing plate 18, a first through hole is provided on the top of the first handle 13, a second sealing gasket 185 is fixedly provided on the bottom of the pressing plate 18, a second through hole is provided on the top of the pressing plate 18, a third through hole is provided on the top of the second sealing gasket 185, a connecting column 183 is inserted into the second through hole, a first sealing gasket 184 is fixedly provided on the bottom of the connecting column 183, the first sealing gasket 184 is inserted into the third through hole, the first sealing gasket 184 and the second sealing gasket 185 is an inverted cone design. When the first sealing gasket 184 is inserted into the third through hole of the second sealing gasket 185, an inverted cone will be formed. The stirring rod is driven by the magnetic stirrer 1 to stir the stirring liquid in the container. When the stirring liquid splashes to the bottom of the second sealing gasket 185, it will flow along the surface of the second sealing gasket 185 and the first sealing gasket 184 to the bottom of the first sealing gasket 184 and drip back into the container to avoid waste of the stirring liquid. The first through hole is aligned with the second through hole and the third through hole. A limit plate 181 is fixed on the top of the connecting column 183. The limit plate 181 is located on the top of the pressure plate 18. A second handle 182 is fixedly provided on the top of the limiting plate 181, and a group of damping shafts 15 are fixedly provided on both sides of the pressure plate 18. The outer wall of the damping shaft 15 is rotatably sleeved with a shaft sleeve 14. A guide rod 16 is fixedly provided on the top of the shaft sleeve 14. A spring 17 is placed on the outer ring of the guide rod 16. The spring 17 is fixedly provided on the top of the shaft sleeve 14. A group of support columns 11 are fixedly provided on both sides of the magnetic stirrer 1. A group of guide grooves are provided on the opposite sides of the two groups of support columns 11. A guide hole is provided through the top of the guide groove. The right side of the support column 11 on the right side of the magnetic stirrer 1 is evenly fixed. There are two sets of elastic holders 12, the electric heating rod of the magnetic stirrer 1 is clamped in the elastic holder 12, the rotating shaft sleeve 14 is slidably set in the guide groove, and the first handle 13 is pulled upward to drive the first sealing gasket 184 to move upward through the pressure plate 18. At this time, the container containing the stirring liquid is placed on the magnetic stirrer 1, and then the first handle 13 is slowly lowered. The spring 17 uses its own elastic force to drive the pressure plate 18 downward through the rotating shaft sleeve 14 and the damping shaft 15, thereby driving the second sealing gasket 185 to press against the top of the container. The guide rod 16 is slidably set in the guide hole, and the guide rod 16 assists the rotating shaft sleeve 14 to move up and down stably.
[0021] Working principle: Pull the first handle 13 to flip backward, thereby driving the pressure plate 18 to flip forward with the damping shaft 15 as the center. At this time, the second sealing gasket 185 and the bottom of the first sealing gasket 184 can be conveniently cleaned, thereby ensuring the convenience of cleaning the device after use. Pull the first handle 13 upward to drive the first sealing gasket 184 upward through the pressure plate 18. At this time, place the container containing the stirring liquid on the magnetic stirrer 1, and then slowly lower the first handle 13. The spring 17 uses its own elastic force to drive the pressure plate 18 downward through the rotating shaft sleeve 14 and the damping shaft 15, thereby driving the second sealing gasket 185 to press against the top of the container. When the first sealing gasket 184 is inserted into the third through hole of the second sealing gasket 185, an inverted cone will be formed. The magnetic stirrer 1 drives the stirrer to stir the stirring liquid in the container. When the stirring liquid splashes to the bottom of the second sealing gasket 185, it will flow along the surface of the second sealing gasket 185 and the first sealing gasket 184 to the bottom of the first sealing gasket 184 and drip back into the container to avoid waste of the stirring liquid. The second handle 182 is pulled upward to drive the connecting column 183 and the first sealing gasket 184 to move upward and be pulled out through the limit plate 181. At this time, the electric heating rod of the magnetic stirrer 1 can be inserted into the container through the first through hole, the second through hole and the third through hole to ensure that the heating and stirring function of the magnetic stirrer 1 can be used normally. The electric heating rod is a two-stage design. When in use, its bottom heating end cannot contact the second sealing gasket 185.
