The inner wall of the box body 1 is fixed A slide rail 414 is fixedly installed, and the support plate 308 is slidably sleeved on the surface of the slide rail 414. By setting a lifting mechanism, when the rotating plate 404 rotates, the connecting shaft 405 and the connecting plate 406 are driven to rotate, so that the linkage rod 407 revolves around the connecting shaft 405 as the center of the circle. Since one end of the connecting rod 402 is rotatably sleeved on the surface of the linkage rod 407, and the other end is rotatably sleeved inside the fixed block 401, the support plate 308 is reciprocatedly lifted and lowered under the limit cooperation of the slide rail 414. The staff injects clean water into the box body 1 through the water inlet 413, and the height of the water surface is lower than the height of the top of the beaker. When the support plate 308 moves downward, the height of the top of the beaker is lower than the height of the water surface, so that the clean water enters the inside of the beaker, and the auxiliary cleaning roller 307 is cleaned. Through the reciprocating lifting of the support plate 308, the water inside the beaker and the water in the box body 1 are constantly dynamically exchanged, and the contaminated water is constantly replaced due to cleaning, thereby making the cleaning effect higher.

When the piston bolt 507 approaches the spline sleeve 304, the cleaning liquid enters into the interior of the liquid outlet nozzle 504 through the liquid outlet 503 and is sprayed out. The liquid outlet nozzle 504 is rotated through the meshing connection of the fifth gear 505 and the sixth gear 506, so that the cleaning liquid splashes out, increasing the spraying area of ​​the cleaning liquid, so that the cleaning liquid can be automatically added to the cleaning of the beaker, thereby improving the cleaning effect.

The cup can automatically adapt. The rebound force of the spring 513 makes the cleaning roller 307 always close to the inner wall of the beaker, and when the cleaning roller 307 moves, it drives the eccentric shaft 306 and the adjusting block 512 to move. The eccentric shaft 306 squeezes the reciprocating groove 514, thereby moving the reciprocating frame 509, so that the distance between the reciprocating frame 509 and the center of the spline sleeve 304 changes, thereby adjusting the reciprocating distance of the reciprocating frame 509, and the reciprocating stroke of the piston bolt 507 in the piston cylinder 501 also changes at the same time. When the diameter of the beaker is larger, the movement stroke of the piston bolt 507 is larger, so that more cleaning liquid is added at a time. When the diameter of the beaker is smaller, the movement stroke of the piston bolt 507 is smaller, so that less cleaning liquid is added at a time, so that the amount of cleaning liquid added can be automatically adapted according to the area of ​​the beaker that needs to be cleaned.

[0030] Specifically, the working process or working principle of the cleaning device for biological experimental consumables is as follows: when in use, open the box door, place the beaker on the support plate 308 and close the box door, start the first motor 325, drive the first follower rod 322 to rotate, thereby driving the third gear 321 and the screw rod 311 to rotate, through the threaded connection between the screw rod 311 and the first lifting rod 315, and the limiting cooperation between the second lifting rod 316 and the limiting rod 312, the first lifting rod 315 and the second lifting rod 316 drive the lifting plate 314 to move downward, and because the spline sleeve 304 is rotatably sleeved inside the lifting ring 313, the lifting ring 313 drives the spline sleeve 304 to rotate without affecting the rotation of the spline sleeve 304. The cleaning roller 307 moves downward, and the cleaning roller 304 moves downward to the inside of the beaker. At the same time, the second follower rod 323 drives one of the second gears 320 to rotate through the cooperation of the first transmission belt 324, so that the gear ring 331 rotates. Through the meshing connection between the plurality of second gears 320 and the gear ring 331, and the limiting effect of the limiting groove 318, the plurality of tooth plates 319 drive the clamping plate 310 to move radially, so that the clamping plate 310 moves from the outer side to the inner side of the fixing ring 317 to clamp the beaker. The second motor 330 is started to drive the fourth follower rod 328 to rotate. Through the cooperation of the second transmission belt 329, the third follower rod 327 drives the half gear 326 to rotate. 26 is meshedly connected with the first gear 302. The half gear 326 rotates once and causes the first gear 302 to rotate half a circle. When the first gear 302 rotates, the spline shaft 303 is driven to rotate, thereby driving the spline sleeve 304 to rotate. Since the eccentric rod 305 is eccentrically arranged on the spline shaft 303, the eccentric shaft 306 rotates with the spline sleeve 304 as the center of the circle, so that the cleaning roller 307 cleans the inner wall of the beaker. When the half gear 326 rotates and disengages from the meshing teeth of the first gear 302, the half gear 326 meshes with the fourth gear 415, so that the fourth gear 415 rotates half a circle when the half gear 326 rotates once. When the fourth gear 415 rotates, the third driving rod 416 is driven to rotate. The cooperation of the third transmission belt 417 and the fourth transmission belt 418 makes the second driving rods 410 on both sides rotate simultaneously, and the second driving rods 410 drive the second bevel gear 411 to rotate. Through the meshing connection of the first bevel gear 409 and the second bevel gear 411, the first bevel gear 409 rotates, thereby driving one of the rotating plates 404 to rotate. When the rotating plate 404 rotates, the connecting shaft 405 and the connecting plate 406 are driven to rotate, so that the linkage rod 407 revolves around the connecting shaft 405 as the center of the circle. Since one end of the connecting rod 402 is rotatably sleeved on the surface of the linkage rod 407, and the other end is rotatably sleeved inside the fixed block 401, the support plate 308 is reciprocatedly lifted and lowered under the limit cooperation of the slide rail 414.The staff injects clean water into the box body 1 through the water inlet 413, and the height of the water surface is lower than the height of the top of the beaker. When the support plate 308 moves downward, the height of the top of the beaker is lower than the height of the water surface, so that the clean water enters the interior of the beaker and assists the cleaning roller 307 in cleaning. The reciprocating lifting of the support plate 308 causes the water inside the beaker and the water in the box body 1 to continuously undergo dynamic water exchange. When the cleaning roller 307 moves downward and enters the beaker, the arc-shaped setting at the bottom of the cleaning roller 307 allows the cleaning roller 307 to automatically adapt to beakers of different calibers. The rebound force of the spring 513 ensures that the cleaning roller 307 is always in close contact with the inner wall of the beaker. When the cleaning roller 307 moves, it drives the eccentric shaft 306 and the adjusting block 512 to move, and the eccentric shaft 306 squeezes the reciprocating groove 514, thereby causing the reciprocating frame 509 to move. When the reciprocating frame 509 reciprocates in the left and right directions, it drives the piston rod 508 and the piston bolt 507 to reciprocate. When the piston bolt 507 is away from the spline sleeve 304, the negative pressure principle allows the cleaning liquid in the water tank 515 to enter the interior of the piston cylinder 501 through the water pipe and the liquid inlet 502. When the piston bolt 507 is close to the spline sleeve 304, the cleaning liquid enters the interior of the liquid outlet nozzle 504 through the liquid outlet 503 and is sprayed out. The fifth gear 505 and the sixth gear 506 are meshed and connected, so that the liquid outlet nozzle 504 rotates, causing the cleaning liquid to splash out, increasing the cleaning liquid The spraying area is adjusted by squeezing the inner wall of the beaker to change the eccentric distance of the eccentric shaft 306 relative to the spline sleeve 304, thereby adjusting the reciprocating distance of the reciprocating frame 509, and the reciprocating stroke of the piston bolt 507 in the piston cylinder 501 also changes at the same time. When the beaker has a larger diameter, the moving stroke of the piston bolt 507 is larger, so that more cleaning liquid is added at a time. When the beaker has a smaller diameter, the moving stroke of the piston bolt 507 is smaller, so that less cleaning liquid is added at a time.
