For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Please refer to the accompanying diagrams in all instruction manuals:

[0027] A test tube cleaning device for chemical experiments includes a cleaning tank 1, a cover plate 2 hinged to the cleaning tank 1, a water-proof plate 3 fixedly installed inside the cleaning tank 1, an isolation frame 4 between the cleaning tank 1 and the water-proof plate 3, a plurality of through holes 5 evenly distributed on the isolation frame 4, a branch pipe 6 corresponding to the through holes 5 inside the cleaning tank 1, a water spray pipe 7 through the through holes 5 on the branch pipe 6, a brush on the outside of the water spray pipe 7, a water inlet pipe 9 on the outside of the cleaning tank 1, the water inlet pipe 9 and the branch pipe 6 are interconnected, the length of the water spray pipe 7 is successively shortened, drain holes 10 are symmetrically distributed on the cleaning tank 1, and a high-efficiency cleaning component for fixing test tubes is provided on the isolation frame 4 corresponding to the water spray pipe 7.

[0028] As described above, the external clean water source is introduced into the spray pipe 7 and the nozzle through the inlet pipe 9 to clean the test tube. The water enters the spray pipe 7 through the branch pipe 6 and is sprayed out through the spray pipe 7 to clean the test tube. The brush can also scrub the inner wall of the test tube, which greatly improves the overall cleaning efficiency.

[0029] As a technical optimization of this utility model, the test tube fixing high-efficiency cleaning component includes a motor 11 fixedly installed outside the cleaning tank 1. The output end of the motor 11 extends into the isolation frame 4 and is fixedly installed with a transmission rod 12. A bevel gear 13 is fixedly installed on the transmission rod 12 corresponding to the through hole 5. A bevel gear 14 is rotatably connected to the inner top surface of the isolation frame 4 corresponding to the bevel gear 13. The bevel gear 13 and the bevel gear 14 mesh with each other. A gear 15 is rotatably connected to the isolation frame 4. The gear 15 and the bevel gear 14 are fixedly connected. A gear 16 is slidably connected in the through hole 5. The gear 15 and the gear 16 mesh with each other. A fixing mechanism is provided on the gear 16 corresponding to the water spray pipe 7. A lifting mechanism is provided on the isolation frame 4 corresponding to the gear 16.

[0030] As can be seen from the above description, when the power supply of motor 11 is turned on, motor 11 drives transmission rod 12 to rotate, drives bevel gear 13 to rotate, drives bevel gear 14 to rotate, drives gear 15 to rotate, thereby causing gear 16 to rotate. The water spray pipe 7 and the brush are fixed, so when the test tube is fixed, the corresponding cleaning can be achieved.

[0031] As a technical optimization of this utility model, the fixing mechanism includes a fixing plate 17 uniformly fixedly installed on the gear 2 16, a spring 18 symmetrically fixedly installed on the fixing plate 17, a clamping plate 19 fixedly installed at the other end of the spring 18, and the clamping plate 19 slidably connected to the gear 2 16.

[0032] As can be seen from the above description, the spring 18 enables the clamping plates 19 to interact and clamp and fix the test tube.

[0033] As a technical optimization of this utility model, the lifting mechanism includes a slide groove 20 located on the lower side of the gear 16, a connecting rod 21 slidably connected in the slide groove 20, a connecting beam 22 fixedly installed between the connecting rods 21, an electric hydraulic rod 23 fixedly installed on the isolation frame 4, and the movable end of the electric hydraulic rod 23 fixedly connected to the connecting beam 22.

[0034] As can be seen from the above description, when the electric hydraulic rod 23 moves up and down, it will drive the connecting beam 22 to move up and down, drive the connecting rod 21 to move up and down, and drive the connected gear 16 to move up and down. The gear 16 can rotate on its own while moving up and down, and achieve a better cleaning effect through the cleaning of the brush.

[0035] As a technical optimization of this utility model, the cleaning box 1 is provided with a control button 8, which is electrically connected to the motor 11 and the electric hydraulic rod 23.

[0036] As can be seen from the above description, pressing control button 8 allows for direct rinsing and scrubbing.

[0037] As a technical optimization of this utility model, the upper part of the clamping plate 19 is arc-shaped;

[0038] As can be seen from the above description, the arc-shaped appearance allows the test tube to be better embedded in the clamp 19, making it more convenient to hold.

[0039] As a technical optimization of this utility model, gear 16 and water spray pipe 7 do not contact each other;

[0040] As can be seen from the above description, when gear 2 16 moves up and down, it will not affect the water spray pipe 7.

[0041] The working process of this utility model is as follows:

[0042] The test tube is placed upside down on gear 16. The spring 18 causes the clamping plates 19 to interact and clamp the test tube. The cover plate 2 is then placed on top, and the control button 8 is pressed. The motor 11 and the electric hydraulic rod 23 start working. The external clean water source is introduced into the spray pipe 7 and the nozzle through the water inlet pipe 9 to clean the test tube. The water enters the spray pipe 7 through the branch pipe 6 and is sprayed out through the spray pipe 7 to clean the test tube. The brush can also scrub the inner wall of the test tube, which greatly improves the overall cleaning efficiency.

[0043] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
