[0022] Please see Figure 1-5As shown, a hematopoietic stem cell culture dish cleaning device includes a workbench 1 and a water inlet 2; the top of the workbench 1 is provided with multiple sets of circular grooves 3; the bottom of the circular grooves 3 is rotatably connected to a rotating rod 4; one end of the rotating rod 4 is provided with a power component; the outer circular wall of the rotating rod 4 is provided with a brush 5; the wall of the circular grooves 3 is provided with a clamping component; the outer circular wall of the water inlet 2 is fixedly connected with multiple sets of water spray pipes 6; one end of the water spray pipe 6 is connected to the bottom of the circular grooves 3; the top of the workbench 1 is fixedly connected with multiple sets of limiting rods 7; the outer circular wall of the multiple sets of limiting rods 7 is slidably connected with a limiting ring 8; the bottom of the limiting ring 8 is fixedly connected with multiple sets of discs 9; the discs 9 match the circular grooves 3; the side wall of the limiting ring 8 is threadedly connected with a threaded rod 10; the threaded rod 10... One end is rotatably connected to the workbench 1. During operation, when the staff inverts the petri dish into the circular groove 3, the clamping device can hold the petri dish in the circular groove 3. Under the action of the power component, all the rotating rods 4 can rotate simultaneously, thereby driving the brush 5 to clean the petri dish. During this process, the researcher rotates the threaded rod 10 to move the limiting ring 8 downward, so that the disc 9 covers the circular groove 3. Then, the external water source is connected to the water inlet 2, and the water source will enter the circular groove 3 from the water inlet 2 through the water spray pipe 6 and spray from bottom to top onto the brush 5 and the inner wall of the petri dish to complete the cleaning process of the petri dish. It can clean a large number of petri dishes in a short time, saving manpower and improving the work efficiency of researchers.

[0023] The power component includes a motor 11; one end of the rotating rod 4 passes through a circular groove 3; multiple sets of first gears 12 are rotatably connected to the bottom of the workbench 1; the first gears 12 are fixedly connected to one end of the rotating rod 4; a gear ring 13 is rotatably connected to the bottom of the workbench 1; the gear ring 13 meshes with the first gears 12; the motor 11 is fixedly connected to the bottom of the workbench 1 via an L-shaped plate; a second gear 14 is provided at the output end of the motor 11; the second gear 14 meshes with the gear ring 13; during operation, the output end of the motor 11 drives the second gear 14 to rotate, thereby driving the gear ring 13 to rotate, which in turn drives the first gear 12 to rotate, and then the rotation of the first gear 12 drives the brushes 5 on the rotating rod 4 to rotate, thus realizing the operation of cleaning the petri dishes by rotating multiple sets of brushes 5 on the workbench 1 simultaneously.

[0024] The clamping component includes a limiting plate 15; the wall of the circular groove 3 is provided with multiple sets of sliding grooves 16; the wall of the sliding groove 16 is slidably connected to the limiting plate 15; a spring is fixedly connected between the limiting plate 15 and the sliding groove 16; the side wall of the limiting plate 15 is rounded; during operation, when the operator inverts the culture dish into the circular groove 3, the outer wall of the culture dish will squeeze the rounded corner of the limiting plate 15, causing the limiting plate 15 to slide in the sliding groove 16 to allow the culture dish to enter the circular groove 3, and then the limiting plate 15 is pressed against the outer wall of the culture dish by the elastic force of the spring, clamping the culture dish in the circular groove 3, which facilitates the operator to place and clamp the culture dish in the circular groove 3.

[0025] The rotating rod 4 includes an upper rod 17 and a lower rod 18. The bottom end of the upper rod 17 is fixed with multiple sets of L-shaped blocks 25. The top end of the lower rod 18 is provided with multiple sets of L-shaped grooves 24. The L-shaped grooves 24 match the L-shaped blocks 25. The brush 5 is fixed to the upper rod 17. The first gear 12 is fixed to the bottom end of the lower rod 18. During operation, by rotating the upper rod 17, the transverse block of the L-shaped block 25 can be disengaged from the transverse groove of the L-shaped groove 24. At this time, the researcher can lift the upper rod 17 upward to disengage it from the lower rod 18, which facilitates the researcher to quickly replace the brush 5 in the workbench 1, improving cleaning efficiency and flexibility.

[0026] The circular groove 3 has a drain outlet 19 on its side wall; a rotating ring 20 is rotatably connected to the inner circular wall of the workbench 1; multiple sets of L-shaped rods 21 are fixedly connected to the side wall of the rotating ring 20; the L-shaped rods 21 are slidably connected to the inner circular wall of the workbench 1; a through groove 22 is provided on the side wall of the rotating ring 20; the through groove 22 matches the drain outlet 19; during operation, researchers push the L-shaped rods 21, which in turn drive the rotating ring 20 to rotate. When the through groove 22 of the rotating ring 20 corresponds to the drain outlet 19, all the cleaning wastewater in the circular groove 3 can be discharged in a timely manner, ensuring that the cleaning process is continuous and thus improving cleaning efficiency.

[0027] A rotating handle 23 is fixedly connected to the top of the threaded rod 10; during operation, the rotating handle 23 on the threaded rod 10 allows researchers to quickly rotate the threaded rod 10, thereby improving work efficiency.

[0028] Working principle: When the staff inverts the petri dish into the circular groove 3, the clamping device holds the petri dish within the groove 3. Under the action of the power component, all the rotating rods 4 rotate simultaneously, causing the brush 5 to clean the petri dish. During this process, the researcher rotates the threaded rod 10, causing the limiting ring 8 to move downwards, covering the circular disc 9 into the circular groove 3. Then, an external water source is connected to the water inlet 2, and water enters the circular groove 3 from the inlet 2 through the spray pipe 6, spraying upwards. The cleaning process is completed by spraying the brush 5 and the inner wall of the culture dish. This allows for the cleaning of a large number of culture dishes in a short time, saving manpower and improving the efficiency of researchers. The output of motor 11 drives the second gear 14 to rotate, which in turn drives the gear ring 13 to rotate. The gear ring 13 then drives the first gear 12, which in turn drives the brush 5 on the rotating rod 4. This allows multiple sets of brushes 5 on the workbench 1 to rotate simultaneously to clean the culture dishes. When the staff places the petri dish upside down into the circular groove 3, the outer wall of the petri dish will press against the rounded corners of the limiting plate 15, causing the limiting plate 15 to slide within the sliding groove 16, allowing the petri dish to enter the circular groove 3. Then, the limiting plate 15, through the elastic force of the spring, presses against the outer wall of the petri dish, clamping the petri dish within the circular groove 3. This facilitates the placement and clamping of the petri dish within the circular groove 3. By rotating the upper rod 17, the researcher can disengage the transverse block of the L-shaped block 25 from the transverse groove of the L-shaped groove 24. At this time, the researcher can lift the upper rod 17 upwards. 7 can be disengaged from the lower rod 18, making it convenient for researchers to quickly replace the brush 5 in the workbench 1, improving cleaning efficiency and flexibility. By pushing the L-shaped rod 21, the researchers can drive the rotating ring 20 to rotate. When the through groove 22 of the rotating ring 20 corresponds to the drain outlet 19, all the cleaning wastewater in the circular grooves 3 can be discharged in time, ensuring that the cleaning process is continuous and thus improving cleaning efficiency. The rotating handle 23 on the threaded rod 10 allows researchers to quickly rotate the threaded rod 10, improving work efficiency.
