Referring to fig. 3, as an embodiment of the present invention, a first liquid storage tank 32 and a second liquid storage tank 33 are fixedly installed on the working tank 1 above the water outlet tank 17, a second through hole 31 and a first through hole 30 are embedded in the sliding plate 27, the first liquid storage tank 32 and the second liquid storage tank 33 are both communicated with the water outlet tank 17, the second through hole 31 and the first through hole 30 respectively correspond to the connection positions of the first liquid storage tank 32 and the second liquid storage tank 33 with the water outlet tank 17, a circular plate 29 is fixedly connected to one end of the sliding plate 27, and a second spring 28 is fixedly installed between the circular plate 29 and the outer wall of the water outlet tank 17.
When all the liquid in the water outlet tank 17 is completely pumped out, the sliding plate 27 is reset under the elastic action of the second spring 28, the moving plate 26 is blocked by the baffle 25 in the moving process, and when the moving plate 26 is completely reset, the second through hole 31 and the first through hole 30 on the sliding plate 27 are overlapped with the first liquid storage tank 32 and the second liquid storage tank 33, so that the supercritical carbon dioxide in the first liquid storage tank 32 and the cleaning liquid in the second liquid storage tank 33 are supplemented into the water outlet tank 17, and the next cleaning work is facilitated.
Referring to fig. 3, as an embodiment of the present invention, a filter screen 35 is fixedly installed on the inner wall of the work box 1 below the clamping mechanism, a sponge block 34 is fixedly installed on the top surface of the filter screen 35, and a water outlet 36 is embedded in the side wall of the work box 1.
When the test tube is cleaned, the motor 3 drives the clamping mechanism to rotate downwards, all liquid in the test tube is poured out, the poured liquid is absorbed by the sponge block 34, the poured liquid can be effectively prevented from splashing back to the test tube again, and the liquid is discharged from the water outlet 36 on the side wall of the working box 1.
Referring to fig. 3 and 1, a rotary wheel 38 is rotatably connected to the inlet 2 by a torsion spring.
When the movable block 6 receives the outside test tube that pushes out of first spring 10 elasticity, the torsional spring then provides the resistance for the test tube that pops out, prevents that the test tube from popping out too fast, makes the test tube drop away.
The working principle is as follows: when using, fill in fixture with the test tube one by one through entry 2 in, fixture is with the test tube centre gripping, motor 3 starts after that, it is vertical state to drive fixture rotation, then electric putter 20 promotes outlet pipe 19 downwards, in filling in the test tube with outlet pipe 19 and the rotary mechanism on the outlet pipe 19, water pump 15 starts, spout the supercritical carbon dioxide in outlet tank 17 to the test tube through outlet pipe 19 in, and make supercritical carbon dioxide evenly spray at the test tube inner wall through rotary mechanism.
