[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-5 As shown, a test tube cleaning and disinfecting device comprises a bottom box 1, a cleaning mechanism 2 is installed on the top of the bottom box 1, a positioning mechanism 3 is installed on the bottom of the cleaning mechanism 2, the cleaning mechanism 2 comprises two lifting columns 4, the two lifting columns 4 are installed on both sides of the top of the bottom box 1, a screw 5 is movably installed inside the lifting columns 4, a first motor 6 is installed on the top of the screw 5, a same horizontal plate 7 is sleeved between the peripheries of the two screws 5, a second motor 8 and five brush rods 9 are respectively installed on the bottom of the horizontal plate 7, a rotating gear 11 is installed on the output shaft of the second motor 8 and the tops of the five brush rods 9, a pipe opening 12 is opened on the top of the rotating gear 11 penetrating the top of five of the brush rods 9, a horizontal tube 13 is installed on the top of the horizontal plate 7, a conduit 14 is installed penetrating the periphery of the horizontal tube 13 and located in each pipe opening 12, and a plurality of through holes 15 are opened on the periphery of the brush rod 9.

[0024] In this embodiment, the two ends of the horizontal plate 7 are sleeved on the outer periphery of the screw rod 5 and are threadedly connected. The brush rod 9 is located at the bottom of the horizontal plate 7 and is movably rotatable. The brush rod 9 is inserted into or detached from the test tube by lifting and lowering the horizontal plate 7 to clean the inside of the test tube.

[0025] In this embodiment, each rotating tooth 11 is arranged in meshing connection, and the brush rod 9 and the rotating teeth 11 are arranged to rotate synchronously. The corresponding rotating teeth 11 are rotated by the second motor 8, and each brush rod 9 rotates synchronously under the meshing action of the rotating teeth 11.

[0026] In this embodiment, the interior of the brush rod 9 is hollow, and the conduit 14 is located in the pipe mouth 12 and matched with each other. It is connected to the water pipe through the cross pipe 13, so that water enters the brush rod 9 through the conduit 14 and then flows out from the through hole 15 to clean the inside of the test tube.

[0027] In this embodiment, the positioning mechanism 3 includes a positioning plate 16, which is movably installed between the two lifting columns 4 at a position near the bottom. A third motor 17 is installed at one end of the positioning plate 16 and on the outside of one of the lifting columns 4. Five adjusting rods 18 are movably installed inside the positioning plate 16. A knob 19 is installed at the front end of the adjusting rod 18. Two positioning blocks 20 are movably installed on the periphery of the adjusting rod 18. A positioning groove 21 is provided on the top of the positioning plate 16 and between every two positioning blocks 20. The test tube is fixed by the positioning groove 21 and the positioning block 20. When the positioning plate 16 rotates, the sewage cleaned inside the test tube can be discharged.

[0028] In this embodiment, the positioning plate 16 and the output shaft of the third motor 17 are arranged to rotate synchronously, and the threads on the outer periphery of the adjusting rod 18 at both ends are arranged in opposite directions. The positioning plate 16 is rotated by the third motor 17, and the fixed test tube is tilted and rotated to discharge the cleaned water inside.

[0029] In this embodiment, an arc groove is provided on the inner side of the positioning block 20, and the positioning block 20 and the adjusting rod 18 are threadedly connected. The positioning block 20 clamps the test tube under the threaded connection of the adjusting rod 18 to prevent movement during the cleaning process.

[0030] It should be noted that the utility model is a test tube cleaning and disinfecting device. When in use, each test tube is first fixed in the positioning groove 21 on the top of the positioning plate 16. When fixing, the knob 19 is rotated to make the adjustment rod 18 drive the positioning block 20 to slide inward, and the test tube is clamped and fixed. When cleaning and disinfecting, the water pipe is connected to the horizontal pipe 13, and the two first motors 6 are started to drive the screw 5 to drive the horizontal plate 7 to descend, so that each brush rod 9 enters each test tube respectively. The corresponding rotating gear 11 is rotated by starting the second motor 8. When the rotating teeth 11 are engaged, the remaining rotating teeth 11 are driven at the same time, and each brush rod 9 is rotated inside the test tube. At the same time, water flows into the horizontal tube 13, and is transported to the inside of the brush rod 9 through the conduit 14 and the pipe mouth 12. Under the action of the rotation of the brush rod 9, the water flows out to the inside of the test tube through the through hole 15 to clean the inner wall of the test tube. After the cleaning is completed, the horizontal plate 7 rises to drive the brush rod 9 to separate from the test tube. By starting the third motor 17, the positioning plate 16 is rotated, which in turn drives the test tube to rotate, and the cleaned water in the test tube is discharged into the bottom box 1 for collection.

[0031] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
