Description

Technical Field

[0001] The utility model relates to the technical field of experimental instruments, in particular to a test tube rinsing device. Background Art

[0002] At present, the cleaning methods of test tubes mainly include the following ways:

[0003] Scrubbing: For test tubes with substances difficult to wash off on the inner wall, a special test tube brush is dipped in a detergent (such as soapy water, synthetic detergent or special laboratory cleaning solution) for scrubbing. When scrubbing, the test tube needs to be rotated or the test tube brush needs to be moved up and down, and attention should be paid to moderate force to avoid damaging the test tube.

[0004] Rinsing: The test tube is thoroughly rinsed with a large amount of clean water to remove all detergents and loose residues. When rinsing, it should be ensured that the water flow covers all the inner surfaces of the test tube until the rinsing water is foam-free and clear.

[0005] However, in most cases of the existing technology at present, the test tubes are rinsed manually. The current manual cleaning method is time-consuming and laborious. Especially in the case of a large laboratory scale or frequent experiments, the efficiency is low. If the rinsing is not thorough, it will affect the accuracy of subsequent experimental results.

The adjusting knob 3 is connected to the partition plate 2. The partition plate 2 is used to press the elastic handle A 601 and the elastic handle B 701 and seal the flushing box body 1. The linkage design of the adjusting knob 3 and the partition plate 2 realizes the pressing and sealing of the water storage tank 6 and the sewage tank 7, effectively preventing water leakage and the entry of external pollutants, and ensuring the cleanliness and safety of the flushing environment.

[0052] At the upper end of the flushing box body 1 of the present utility model, a water retaining convex edge 101 is integrally connected, which can prevent water from overflowing during the flushing process, protect the laboratory table from water stains, reduce potential safety hazards in the laboratory environment, and keep the working area clean and safe.

[0053] Working process:

[0054] First, the user places the flushing device at an appropriate position in the laboratory, ensuring that the supporting base 5 contacts the tabletop smoothly to provide a stable foundation. Then, an appropriate amount of cleaning water is added to the water storage tank 6, and the water storage tank 6 is placed inside the flushing box body 1. The convex strip A602 is lapped on the guiding plate A103, and the positioning insert A104 is inserted into the groove A603 to ensure the stable positioning of the water storage tank 6. The sewage tank 7 is also installed at the designated position of the flushing box body 1 through the cooperation of the convex strip B702 and the guiding plate B106, as well as the positioning insert B105 and the groove B703.

[0055] By adjusting the adjusting knob 3 on one side of the flushing box body 1, the partition plate 2 moves downward to press the elastic handle A601 and the elastic handle B701, realizing the sealing of the water storage tank 6 and the sewage tank 7, preventing water leakage, and ensuring the sealing inside the flushing box body 1.

[0056] After the power is turned on, the flushing water pump 9 starts to work. The water pump sucks clear water from the water storage tank 6 through the suction pipe 8. After being pressurized by the pump body, the clean water is transmitted to the flushing insertion tube 1021 in the water outlet hole 1023 through the elbow 10.

[0057] Process of flushing the test tube: Insert the test tube to be cleaned into the flushing insertion tube 1021 (during the flushing process, the flushing insertion tube 1021 needs to be held by hand). The flushing water pump 9 continues to work, spraying water upward to perform a strong and precise flushing on the test tube.

[0058] The sewage generated during the cleaning process flows back to the cleaning tank 102 through the test tube and enters the fixed sleeve 12 through the water return hole 1022, and then is guided to the sewage tank 7 by the water outlet pipe 11.

[0059] After the cleaning is completed, turn off the power of the flushing water pump 9, open the partition plate 2, and pull the elastic handle A601 and the elastic handle A601B to easily take out the water storage tank 6 and the sewage tank 7 for water replacement or cleaning.
