The working principle is as follows:
when the device needs to be used, a worker manually opens the box body cover 2, inserts the test tubes into the cleaning sleeves 8 in the cleaning grooves 3 one by one, and after the test tubes are inserted into the cleaning grooves, the bottoms of the test tubes are exposed outside the cleaning sleeves 8 due to the support of the annular fixing plates 11 on the test tubes, so that the test tubes are convenient to take and place for the worker;
after the test tube is inserted, the operator starts to operate through the controller 43, at this time, the controller 43 controls the electric telescopic rod 17 to start to operate, the electric telescopic rod 17 extends out to drive the adjusting plate 18 to start to descend, so that the adjusting plate 18 drives the adjusting rod 16 to start to descend, and the descending of the adjusting rod 16 drives the annular fixing plate 11 to start to descend, so that the annular fixing plate 11 moves towards the bottom of the cleaning sleeve 8, the test tube descends synchronously through self gravity in the moving process of the annular fixing plate 11, after the annular fixing plate 11 descends to a certain degree, the inverted-boss type rubber soft cap 10 at the upper end of the water return exhaust tube 9 contacts with the bottom of the test tube, so as to support the test tube, at this time, the annular fixing plate 11 descends continuously, and after the annular fixing plate 11 descends to a certain degree, the electric telescopic rod 17 at this time is in a completely extending state, at this time, the controller 43 controls the electric telescopic rod 43 to stop working;
at the moment, the test tube is completely inserted into the cleaning sleeve in an inverted manner, a worker manually covers the box body cover 2 on the cleaning groove 3, at the moment, the controller 43 controls the first water suction pump 27 to start working, clear water in the glass water tank 22 enters the water suction pipe 26 through the first water suction pump 27, then enters the water inlet pipe 4 through the water suction pipe 26, then is injected into the circular cleaning seat 7 through the water inlet pipe 4, along with the continuous injection of the clear water, the water level in the circular cleaning seat 7 is continuously increased, after the water level is higher than the cleaning sleeve 8, the clear water starts to be injected into the cleaning sleeve 8 and is contained above the annular fixing plate 11, at the moment, along with the continuous injection of the clear water, the test tube is gradually submerged by the clear water, after the first water suction pump 27 works for a certain time, at the moment, the water level in the cleaning sleeve 8 completely submerges the test tube and fully fills the cleaning sleeve 8, at the moment, air still remains in the test tube, so that the interior of the test tube cannot be filled with clear water;
at the moment, the first water suction pump 27 works for a certain time and continues to work, and at the moment, the controller 43 controls the second water return electromagnetic valve 40 and the filtered water return electromagnetic valve 37 to be opened, and the second water suction pump 41 is controlled to start working, along with the working of the second water suction pump 41, residual air in the test tube enters the backwater exhaust pipe 9 through the inverted boss type rubber soft cap 10, and enters the second filtering water inlet pipe 39 through the backwater extraction pipe 9, enters the first filtering water inlet pipe 38 through the second filtering water inlet pipe 39, and is extracted by the second suction pump 41 to pump air into the filtering sleeve 29, the air then passes through the filter cartridge 2, into the filter return 36, then into the glass tank 22, the inside of the glass water tank 22 forms negative pressure along with the continuous pumping of water, and the injected air can continuously supplement air pressure to the glass water tank 22, so that the safe use of the glass water tank 22 is ensured;
the gas in the test tube is gradually extracted along with the continuous work of the second water suction pump 41 until the test tube is completely extracted, at the moment, after the second water suction pump 41 is extracted for a certain time, the controller 43 controls the second water return electromagnetic valve 40 and the second water return filtering electromagnetic valve 37 to be closed, controls the first water suction pump 27 and the second water suction pump 41 to stop working, controls the ultrasonic generator 28 to start working, generates a high-frequency oscillation signal by the ultrasonic generator 28, converts the high-frequency oscillation signal into high-frequency mechanical oscillation through the first ultrasonic transducer 14, and transmits the high-frequency mechanical oscillation to the clean water, so that the clean water generates a cavitation effect and a straight-flow effect, and the test tube is cleaned;
when the ultrasonic generator 28 works for a certain time, the controller 43 controls the water return solenoid valve two 40 and the filtering water return solenoid valve 37 to be opened again, and controls the water suction pump one 27 and the water suction pump two 41 to start working at the same time, and at the same time, the clean water circulates through the work of the water suction pump one 27 and the water suction pump two 41 and is filtered through the reverse osmosis membrane water purification filter element 30, so that the cleanliness of the clean water is ensured, and when the clean water circulates, the clean water inside the cleaning sleeve 8 is injected through the circular cleaning seat 7 and is extracted through the water return exhaust pipe 9, so that the clean water flows in the cleaning sleeve 8, and the flow rate of the clean water is low, so that the ultrasonic cleaning cannot be influenced, but impurities generated by the ultrasonic cleaning enter the water return exhaust pipe 9 along with the flow of the clean water due to the flow of the clean water, so that the clean water is used for cleaning in the cleaning sleeve 8 all the time, thereby ensuring the cleanliness of the test tube;
