DETAILED DESCRIPTION

[0032] The present invention will be further described below with reference to the accompanying drawings and examples. Example 1

[0033] A laboratory flask cleaning device, such as Figure 1 and Figure 2 As shown, it includes a first support rod 1 , a rotating mechanism 2 and an unfolding mechanism 3 . The rotating mechanism 2 is arranged on the first support rod 1 , and the unfolding mechanism 3 is arranged on the rotating mechanism 2 .

[0034] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the rotating mechanism 2 includes a supporting ring 21, an inclined block 22, a second supporting rod 23 and a first torsion spring 24. The supporting ring 21 is movably connected to the lower part of the first supporting rod 1, and the second supporting rod 23 is connected to the lower part of the supporting ring 21. Four inclined blocks 22 are evenly installed on the lower part of the first supporting rod 1, and four inclined blocks 22 are evenly installed on the upper part of the second supporting rod 23. The upper inclined blocks 22 correspond to the lower inclined blocks 22 one by one, and the corresponding inclined blocks 22 are in contact with each other. The first torsion spring 24 is connected between the second supporting rod 23 and the first supporting rod 1.

[0035] like Figure 1 、 Figure 2 、 Figure 6 and Figure 7 As shown, the unfolding mechanism 3 includes a third support rod 31, a first cleaning ring 32, a fourth support rod 33, a moving block 34, a fifth support rod 35 and a second spring 36. The third support rod 31 is connected to the bottom of the second support rod 23, and the moving block 34 is slidably connected to the lower part of the third support rod 31. The moving block 34 is evenly circumferentially mounted with four fourth support rods 33 through bearings. The sides of the fourth support rods 33 away from each other are each mounted with a first cleaning ring 32 through a bearing. The first cleaning rings 32 are all arc-shaped and made of elastic material. The fifth support rod 35 is slidably connected to the lower part of the third support rod 31. The fifth support rod 35 is located below the moving block 34. The second spring 36 is wound around the fifth support rod 35. The upper and lower ends of the second spring 36 are respectively fixed to the third support rod 31 and the fifth support rod 35.

[0036] When it is necessary to clean the inside of a round-bottom flask, the present laboratory flask cleaning device can be used. People first inject clean water into the round-bottom flask, then hold the first support rod 1, put the present laboratory flask cleaning device into the round-bottom flask, and make the fifth support rod 35 contact the inner bottom wall of the round-bottom flask. As the present laboratory flask cleaning device continues to enter the round-bottom flask, the fifth support rod 35 is forced to move upward, the second spring 36 is compressed, and the fifth support rod 35 moves upward until it contacts the moving block 34. The fifth support rod 35 squeezes the moving block 34 and moves upward, thereby The first cleaning ring 32 is moved outward by the fourth support rod 33 until it contacts the inner wall of the circular part of the round-bottom flask. Since the first cleaning ring 32 is elastic, the first cleaning ring 32 can fit the inner wall of the round-bottom flask regardless of the size of the round-bottom flask, and has strong applicability. Then, the first support rod 1 is pressed, so that the upper inclined block 22 presses the lower inclined block 22 downward, thereby rotating the second support rod 23, and the first torsion spring 24 is torsionally deformed. The second support rod 23 causes the third support rod 31 to rotate, thereby rotating the moving block 34, and then The first cleaning ring 32 is rotated by the fourth support rod 33, and the rotation of the first cleaning ring 32 can wipe the inner wall of the circular part of the round-bottom flask, and can wipe off the stains remaining inside the round-bottom flask, thereby improving the cleaning effect. After the round-bottom flask is cleaned, the laboratory flask cleaning device is pulled up, and the first support rod 1 moves upward. The upper inclined block 22 no longer squeezes the lower inclined block 22, and the first torsion spring 24 is reset to make the second support rod 23 reverse and reset. The second support rod 23 makes the third support rod 31 reverse, thereby making the moving block 34 reverse, and the moving The block 34 reverses the first cleaning ring 32 through the fourth support rod 33, and the first cleaning ring 32 wipes the inner wall of the round-bottom flask again, further improving the cleaning effect. The laboratory flask cleaning device moves upward so that the fifth support rod 35 no longer squeezes the inner bottom of the round flask, and the second spring 36 resets the fifth support rod 35 to move downward, thereby causing the moving block 34 to move downward. The moving block 34 causes the first cleaning ring 32 to move inward and shrink through the fourth support rod 33, and then the laboratory flask cleaning device can be removed and the water in the round-bottom flask can be poured out. Example 2

[0037] On the basis of Example 1, Figure 1 、 Figure 2 、 Figure 8 、 Figure 9 and Figure 10As shown, it also includes a wiping mechanism 4, which includes a second cleaning ring 41, a first support plate 42, a telescopic rod 43, a third spring 44 and a second torsion spring 45. A number of telescopic rods 43 are evenly installed circumferentially on the lower inner part of the second support rod 23, and the telescopic parts of the telescopic rods 43 are each installed with a second cleaning ring 41. The telescopic rods 43 are each wound with a third spring 44. The inner and outer ends of the third spring 44 are respectively fixed to the fixed part of the telescopic rod 43 and the second cleaning ring 41. The lower part of the second cleaning ring 41 is installed with a first support plate 42 through a bearing, and two second torsion springs 45 are wound around the rotating connection between the second cleaning ring 41 and the first support plate 42. The inner and outer ends of the second torsion spring 45 are respectively fixed to the first support plate 42 and the second cleaning ring 41. The first support plate 42 corresponds to the first cleaning ring 32 one by one, and the first cleaning ring 32 presses against the corresponding first support plate 42.

[0038] Initially, the first cleaning ring 32 is against the first support plate 42, the second torsion spring 45 is torsionally deformed, and the third spring 44 is compressed. When the first cleaning ring 32 moves outward and opens, the elastic force of the second torsion spring 45 causes the first support plate 42 to rotate outward and expand. The elastic force of the third spring 44 causes the second cleaning ring 41 to move outward. The second cleaning ring 41 causes the first support plate 42 to move outward until it contacts the inner wall of the straight tube near the circular part of the round-bottom flask. The rotation of the second support rod 23 causes the telescopic rod 43 to rotate, thereby The second cleaning ring 41 rotates, thereby causing the first support plate 42 to rotate. The first support plate 42 rotates to scrub the inner wall of the straight tube near the circular part of the round-bottom flask, thereby improving the cleaning effect of the round-bottom flask. When the first cleaning ring 32 moves inward and retracts, the first cleaning ring 32 squeezes the first support plate 42 to rotate inward, and the second torsion spring 45 undergoes torsional deformation. After the first support plate 42 rotates inward to the limit, the first cleaning ring 32 causes the second cleaning ring 41 to move inward through the first support plate 42, and the third spring 44 is compressed.

[0039] like Figure 1 、 Figure 2 、 Figure 11 and Figure 12 As shown, it also includes a wiper mechanism 5, which includes a second support plate 51, a cleaning block 52, a sixth support rod 53 and a third torsion spring 54. The sixth support rod 53 is installed on the side away from each other in the middle of the first cleaning ring 32, and the second support plate 51 is installed on the sixth support rod 53 through a bearing. The cleaning block 52 is installed on the second support plate 51, and two third torsion springs 54 are wound around the rotating connection between the second support plate 51 and the sixth support rod 53. The inner and outer ends of the third torsion spring 54 are respectively fixed to the cleaning block 52 and the sixth support rod 53.

[0040] When the first cleaning ring 32 moves outward and expands, the first cleaning ring 32 causes the second supporting plate 51 to move outward through the sixth supporting rod 53, thereby causing the cleaning block 52 to move outward to squeeze the inner wall of the round-bottom flask. The cleaning block 52 is forced to rotate upward, thereby causing the second supporting plate 51 to rotate upward, and the third torsion spring 54 is torsionally deformed. The torsional force of the third torsion spring 54 causes the cleaning block 52 to cling to the inner wall of the round-bottom flask. While the cleaning block 52 is clinging to the inner wall of the round-bottom flask, when the first cleaning ring 32 rotates, the first cleaning ring 32 causes the cleaning block 52 to rotate through the sixth supporting rod 53 and the second supporting plate 51, and the cleaning block 52 scrapes the stains on the inner wall of the round-bottom flask, thereby cleaning more stubborn stains, which is beneficial to improving the cleaning effect of the round-bottom flask. When the laboratory flask cleaning device is removed and the cleaning block 52 is separated from the round-bottom flask, the third torsion spring 54 resets the cleaning block 52 through the second supporting plate 51.

[0041] like Figure 2 、 Figure 13 and Figure 14 As shown, it also includes a bottom wiping mechanism 6, which includes a bottom wiping sponge 61, a fourth support plate 62, a fifth support plate 63, a fifth spring 64, a seventh support rod 65 and a guide rod 66. The fourth support plate 62 is installed on the left front side and the right rear side of the moving block 34 through bearings, and the fifth support plate 63 is installed on the lower part of the fourth support plate 62 through bearings. The lower part of the third support rod 31 is connected to the guide rod 66, and the rotating connection between the fourth support plate 62 and the fifth support plate 63 is slidably connected to the guide rod 66, and the lower part of the fifth support plate 63 is installed with a seventh support rod 65 through a bearing. The bottom wiping sponge 61 is slidably connected between the seventh support rod 65, and the bottom wiping sponge 61 semi-encloses the third support rod 31. The fifth spring 64 is fixed between the seventh support rod 65 and the bottom wiping sponge 61, and the upper left front side and right rear side of the bottom wiping sponge 61 are provided with grooves for the movement of the fifth support plate 63.

[0042] The fifth support plate 63 rotates outwards, causing the bottom wiping sponge 61 to move upwards and reset, and the rotating connection between the fourth support plate 62 and the fifth support plate 63 moves inwards on the guide rod 66.

[0043] like Figure 1 、 Figure 2 、 Figure 15 and Figure 16 As shown, it also includes a heating mechanism 7, which includes a heating plate 71, a third support plate 72, a first extrusion block 73, a fourth spring 74 and a sensor 75. The heating plate 71 is mounted on the fifth support rod 35, and the sensor 75 is connected to the top of the heating plate 71. The sensor 75 is electrically connected to the heating plate 71, and the sensor 75 controls the switch of the heating plate 71. The third support plate 72 is rotatably connected to the inside of the heating plate 71, and the third support plate 72 is located below the sensor 75. The third support plate 72 is located below the bottom wiping sponge 61, and the first extrusion block 73 is slidably connected to the right side inside the heating plate 71. The side of the first extrusion block 73 close to the third support plate 72 is tilted toward the lower left, and the third support plate 72 contacts the first extrusion block 73. The fourth spring 74 is wound around the first extrusion block 73, and the left and right ends of the fourth spring 74 are respectively fixed to the first extrusion block 73 and the heating plate 71.

[0044] After pouring out the water inside the round-bottom flask, the bottom wiping sponge 61 moves downward to press the third support plate 72, causing the third support plate 72 to rotate forward and downward. The rear of the third support plate 72 presses the sensor 75, thereby starting the heating plate 71. The heating plate 71 heats the inside of the round-bottom flask, thereby quickly drying the water inside the round-bottom flask, which is beneficial to improving the cleaning efficiency of the inside of the round-bottom flask. The third support plate 72 rotates forward to squeeze the first squeezing block 73 to move right, and the fourth spring 74 is compressed. The bottom wiping sponge 61 moves upward to release the third support plate 72. The fourth spring 74 is reset to cause the first squeezing block 73 to move left, and the first squeezing block 73 squeezes the third support plate 72 to rotate backward and upward to reset.

[0045] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge of those skilled in the art without departing from the spirit of the present invention.
