[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0024] Please see Figure 1 - Figure 7This utility model provides an embodiment of a stem cell culture dish cleaning and drying device, including a cleaning and drying cabinet body 1, a limiting mesh frame 212, and a conveying assembly. A cleaning and drying cabinet door panel 4 is provided inside the cleaning and drying cabinet body 1. A storage box body 5 is fixedly connected to the right end of the cleaning and drying cabinet body 1, and a storage box door panel 6 is provided inside the storage box body 5. A conveying assembly is provided on the outside of the cleaning and drying cabinet body 1. The limiting mesh frame 212 is fixedly connected inside the cleaning and drying cabinet body 1, and a placement mesh frame 213 is fixedly connected inside the cleaning and drying cabinet body 1. A connecting plate 214 is fixedly connected inside the cleaning and drying cabinet body 1, and the connecting plate 214 is fixedly connected between the limiting mesh frame 212 and the placement mesh frame 213. The rear end of the storage box body 5 is fixedly connected... A first electric telescopic rod 215 is fixedly connected. The telescopic end of the first electric telescopic rod 215 is slidably connected inside the washing and drying cabinet body 1. A toothed plate 216 is fixedly connected to the telescopic end of the first electric telescopic rod 215. The toothed plate 216 is slidably connected inside the washing and drying cabinet body 1. A circular gear 218 meshes with the outside of the toothed plate 216. An optical shaft 217 is fixedly connected inside the circular gear 218.

The toothed plate 216 drives the cleaning strip 220 to reciprocate. The first electric telescopic rod 215 is activated by activating the toothed plate 216. The telescopic rod 215 extends and retracts, causing the toothed plate 216 to slide back and forth inside the cleaning and drying cabinet body 1. Both sets of toothed plates 216 mesh with circular gears 218, causing the lower toothed plate 216 to move back and forth. This is slidably connected to the connecting plate 214 via the connecting rod 219, causing a lifting motion on the placement frame 213, thus moving the petri dishes and improving cleaning efficiency. The conveying component extends and retracts via the third electric telescopic rod 35, causing the baffle 37 to move upwards inside the cleaning and drying cabinet body 1, releasing the restriction on the rectangular tube 34. Then, the second electric telescopic rod 31 extends and retracts, passing through a limiting shaft 33. The system works in conjunction with the push plate 32 to push the petri dishes placed on the mesh frame 213 into the storage box body 5 for sterilization. Two sets of toothed plates 216 are symmetrically distributed at the upper and lower ends of the circular gear 218, allowing them to guide the petri dishes on top of the mesh frame 213, improving the cleaning effect. The washing and drying cabinet body 1 has grooves at corresponding positions of the two sets of toothed plates 216, which slide within these grooves to limit their movement and improve stability. The connecting plate 214 has grooves at corresponding positions of the connecting rod 219, which slides within these grooves to move the cleaning strip 220.This improves the cleaning effect on petri dishes.
[0025] Please see Figure 2 - Figure 4 , Figure 6 - Figure 7 In this embodiment, a water pump 21 is fixedly connected to the top of the washing and drying cabinet body 1. An inlet pipe 22 is installed inside the water pump 21. A universal joint 23 is installed at the end of the inlet pipe 22 away from the water pump 21. The universal joint 23 is fixedly connected inside the washing and drying cabinet body 1. A cleaning nozzle 24 is installed at the top of the universal joint 23. The cleaning nozzle 24 is rotatably connected inside the washing and drying cabinet body 1. A driven gear 25 is fixedly connected inside the cleaning nozzle 24. A driving gear 26 meshes with the outside of the driven gear 25. An internal motor 27 is fixedly connected, and a drive gear 26 is fixedly connected to the output end of the motor 27. A heating box 28 is fixedly connected to the top of the washing and drying cabinet body 1, and a fan 29 is fixedly connected to the top of the heating box 28. A filter screen 210 is installed inside the fan 29. The end of the fan 29 away from the filter screen 210 is located inside the heating box 28. A heating rod 211 is fixedly connected inside the heating box 28 to improve the cleaning effect of the water flow on the petri dish, making the cleaning thorough and less likely to leave dead corners, thereby improving the effect of subsequent use and enhancing the practicality of the device.
[0026] Please see Figure 1 , Figure 5 In this embodiment, the conveying assembly includes a second electric telescopic rod 31, which is fixedly connected to the left end of the washing and drying cabinet body 1. The telescopic end of the second electric telescopic rod 31 is slidably connected inside the washing and drying cabinet body 1. A push plate 32 is fixedly connected to the telescopic end of the second electric telescopic rod 31. A limit shaft 33 is fixedly connected to the left end of the push plate 32, and the limit shaft 33 is slidably connected inside the washing and drying cabinet body 1. The push plate 32 is disposed inside the washing and drying cabinet body 1. A washing strip 220 is disposed at the bottom of the push plate 32. A rectangular tube 34 is fixedly connected between the washing and drying cabinet body 1 and the storage box body 5. A baffle 37 is slidably connected, and a square plate 36 is fixedly connected to the right end of the baffle 37. A third electric telescopic rod 35 is fixedly connected to the right end of the cleaning and drying cabinet body 1. The square plate 36 is fixedly connected to the telescopic end of the third electric telescopic rod 35. An ultraviolet germicidal lamp 38 is fixedly connected inside the storage box body 5 to prevent bacterial growth and improve the cleaning efficiency of the petri dishes. The cleaning and drying cabinet body 1 has a groove at the corresponding position of the baffle 37. The baffle 37 slides in the groove to limit the position of the baffle 37, so that the rectangular tube 34 is blocked during cleaning. When it is necessary to transport the petri dishes, it is opened to improve stability.
[0027] During operation, the door panel 4 of the cleaning and drying cabinet is opened, and the stem cell culture dishes to be cleaned are placed sequentially on the placement mesh frame 213. The mesh frame 212 and the connecting plate 214 are connected to ensure the culture dishes are inside. The water pump 21 is activated to draw external water into the inlet pipe 22. The water flows through the universal joint 23 into the cleaning nozzle 24, where it is sprayed out. The motor 27 drives the drive gear 26 to rotate, causing the driven gear 25 to rotate. This drives the cleaning nozzle 24 through the universal joint 23, cleaning the culture dishes. During cleaning, the first electric telescopic rod 215 is activated to extend and retract, causing the toothed plate 216 to slide back and forth inside the cleaning and drying cabinet body 1. Both sets of toothed plates 216 mesh with circular gears 218, causing the lower toothed plate 216 to move back and forth, moving through the connecting rod 219. The sliding connection inside the connecting plate 214 allows the petri dishes placed on the mesh frame 213 to move in a similar manner, thus improving the cleaning efficiency of the petri dishes. After cleaning, the fan 29 and heating rod 211 are activated, causing the fan 29 to draw outside air into the heating chamber 28. The incoming air is filtered through the filter screen 210 and heated by the heating rod 211. The air then enters the cleaning and drying chamber 1 through the pipe between the heating chamber 28 and the cleaning and drying chamber 1 to dry the cleaned petri dishes. After the petri dishes are dried, the third electric telescopic rod 35 is extended and retracted, causing the baffle 37 to move upward inside the cleaning and drying chamber 1, releasing the restriction on the rectangular tube 34. Then, the second electric telescopic rod 31 is activated and extended and retracted, cooperating with a limiting shaft 33, so that the push plate 32 pushes the petri dishes placed on the mesh frame 213 into the storage box 5 for sterilization.
[0028] Through the above steps, the cleaning strip 220 is moved back and forth to support the culture dish on top of the mesh frame 213, thus solving the problem of incomplete cleaning and leaving dead corners, which would affect subsequent cell culture experiments.
