[0002] Currently, many laboratories rely on manual operation for cleaning test tubes used for cell culture. In practice, test tube brushes are used to apply cleaning agents, which is inefficient and cannot meet the cleaning needs of large batches of test tubes.

[0003] The applicant found through a search that a Chinese patent discloses "a test tube cleaning device" with the publication number "CN223352488U". The brush roller set in this patent can only clean the inner wall of the test tube and cannot clean the outer wall of the test tube, so the cleaning is not comprehensive enough. Therefore, we propose a test tube cleaning device for cell culture. Utility Model Content

[0004] The purpose of this invention is to provide a test tube cleaning device for cell culture.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a test tube cleaning device for cell culture, comprising a body, wherein a support is slidably installed inside the body, and test tube cleaning devices are fixedly installed at both ends of the support.

[0026] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0027] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0028] Please see the appendix Figure 1 -Appendix Figure 7 This utility model discloses a test tube cleaning device for cell culture, including a body 1, a wastewater tank 2 is provided on the bottom side inside the body 1, and a drain pipe is provided at the outlet end of the wastewater tank 2. After cleaning, the drain pipe can be opened by a valve. A support 3 is removable inside the body 1, and a test tube cleaning device 4 is fixedly installed at both ends of the support 3.

[0029] In Example 1, the test tube cleaning device 4 includes an adjustment component 41, which is located at both ends of the support 3. An inner and outer wall cleaning component 43 is fixedly installed on the top side of the adjustment component 41. The inner and outer wall cleaning component 43 includes a hollow rotating rod 432. A connecting pipe 433 is fixedly connected to the through holes on both sides above the hollow rotating rod 432. A hollow arc plate 434 is fixedly connected to the other side of the connecting pipe 433. A nozzle 435 is arranged in an array at one end of the inner side of the hollow arc plate 434. A second nozzle 436 is symmetrically arranged at both ends of the hollow rotating rod 432. A brush group 437 is symmetrically arranged at the other two ends of the hollow rotating rod 432.

[0030] Specifically, the adjustment component 41 includes upright plates 411, which are symmetrically arranged at both ends of the support 3. Each of the two upright plates 411 has a mounting frame 412 fixedly connected to one of its outer ends. A threaded rod 413 is provided in one upright plate 411 through a bearing, and a knob is provided on the top side of the threaded rod 413. A guide rod 414 is fixedly connected in the other mounting frame 412. Movable blocks 415 are fitted on the outer walls of both the threaded rod 413 and the guide rod 414. A support plate 416 is bolted between the two movable blocks 415.

[0031] In this embodiment, the user rotates the knob to raise or lower the movable block 415 located outside the threaded rod 413, while the movable block 415 on the guide rod 414 slides, causing the support plate 416 to rise or fall. This positions the second nozzle 436 and the brush assembly 437 inside the test tube, enabling the inner wall to be brushed. Meanwhile, the hollow arc plate 434 is located outside the test tube, and the outer side of the test tube is rinsed by the first nozzle 435, thus achieving simultaneous cleaning of the inner and outer walls of the test tube.

[0032] Specifically, the hollow rotating rod 432 has mounting grooves 4321 arranged on both outer surfaces. Each side wall of the mounting groove 4321 has a limiting groove 4323. Each limiting groove 4323 is slidably connected to a limiting component 4324. Each end of the inner surface of the mounting groove 4321 is provided with a spring 4322, which is connected to the brush assembly 437.

[0033] In this embodiment, the brush assembly 437 is mounted on the hollow rotating rod 432 by a spring 4322 and a limiting member 4324. At low speed, the brush bristles retract, making it easier for the brush bristles to enter the test tube. At high speed, the centrifugal force causes the brush bristles to be thrown outward, pressing against the test tube wall, resulting in a better cleaning effect.

[0034] Specifically, a top plate 431 is fixedly connected between the top sides of the two upright plates 411. A water tank 44 is installed on the top plate 431. The water outlet end of the bottom side of the water tank 44 is connected to the hollow rotating rod 432 through a bearing. Two adjacent hollow rotating rods 432 are connected by a transmission wheel and a transmission belt, and one end of the transmission wheel is connected to the motor through the transmission belt.

[0035] In this embodiment, by starting the motor, the conveyor belt drives each hollow rotating rod 432 to rotate, thereby achieving rotary cleaning.

[0036] In the second embodiment, a fixing component 42 is arranged between the adjusting components 41, and the fixing component 42 includes a screw 422, with a fixing block 423 movably connected to one side of the screw 422;

[0037] Specifically, the fixing component 42 includes a base 421, which is arranged on the support plate 416. The screw 422 is threaded at both ends of the base 421, and the inner side of the fixing block 423 is designed in a V shape.

[0038] In this embodiment, the fixing block 423 and screw 422 clamp the test tube and ensure that the test tube is held in the center position, thereby improving the cleaning effect. In addition, the fixing block 423 is provided with anti-slip texture on the inner side to improve the clamping stability.

[0039] Working principle:

[0040] First, remove the bracket 3 and place the test tubes to be cleaned into each base 421. Rotate the screws 422 on both sides to clamp the test tubes in place using the fixing blocks 423. Then, the user rotates the knob to rotate the threaded rod 413, causing the movable block 415 located outside the threaded rod 413 to rise and fall. At the same time, the movable block 415 on the guide rod 414 slides, causing the support plate 416 to rise and fall. This positions the nozzle 436 and brush assembly 437 inside the test tube, while the hollow arc plate 434 is positioned outside the test tube. Push the bracket 3 to place it inside the machine body 1, start the motor to drive each hollow rotating rod 432 to rotate, so that the second nozzle 436 and the brush group 437 can brush the inner wall, and the first nozzle 435 can rinse the outside of the test tube. The brush group 437 is installed on the hollow rotating rod 432 by the spring 4322 and the limiting member 4324. When rotating at high speed, the centrifugal force causes the bristles to be thrown outward and pressed against the test tube wall, resulting in a better cleaning effect. After cleaning, take out the test tube and invert it to drain the water. At this point, the entire process is completed.
