[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution:

[0024] A cell culture medium preparation device includes a housing 1, a fixing plate 2 fixedly installed inside the housing 1, and multiple sets of mixing tanks 3 fixedly installed inside the housing 1 and the fixing plate 2. Each set of mixing tanks 3 has a first sealing cover 15 fixedly installed inside, and a stirring rod 7 is movably installed inside the first sealing cover 15. A driven gear 12 is fixedly installed at the upper end of the stirring rod 7. A drive motor 4 is fixedly installed at the bottom of the fixing plate 2. The output shaft of the drive motor 4 is fixedly connected to a rotating rod 5 through a coupling. A drive gear 6 is fixedly installed at the upper end of the rotating rod 5. The drive gear 6 meshes with multiple sets of driven gears 12. The bottom of each set of mixing tanks 3 is connected to a discharge pipe 16, and a first sealing valve 17 is provided on the discharge pipe 16.

[0025] In an optional embodiment: an annular tube 9 is fixedly installed at the bottom of the first sealing cover 15, and multiple sets of nozzles 10 are arranged in a ring array on the annular tube 9. A water inlet pipe 13 is connected to the annular tube 9 and passes through the first sealing cover 15. A cleaning brush 14 for cleaning the inner wall of the mixing tank 3 is fixedly installed on the stirring rod 7, and the bristles of the cleaning brush 14 are in contact with the inner wall of the mixing tank 3.

[0026] It should be noted that the water inlet pipe 13 is connected to the water supply equipment, which supplies water to the water inlet pipe 13. The water is then transported through the ring pipe 9 and the nozzle 10 to the mixing tank 3. The cleaning brush 14 is rotated by the drive motor 4, driven gear 12, rotating rod 5 and stirring rod 7 to clean the mixing tank 3. This can prevent cross-contamination when preparing different cell culture media.

[0027] In an optional embodiment, two sets of ultraviolet sterilization lamps 11 for sterilizing the mixing tank 3 are symmetrically fixedly installed at the bottom of the first sealing cover 15.

[0028] It should be noted that by setting up the ultraviolet sterilization lamp 11, the number of microorganisms inside the mixing tank 3 can be reduced and the risk of contamination can be lowered by activating the ultraviolet sterilization lamp 11 to sterilize and disinfect the inside of the mixing tank 3.

[0029] In an optional embodiment: a fixing frame 8 is fixedly installed at the bottom of the mixing tank 3, a positioning rod 24 is movably installed inside the fixing frame 8, a conical block 22 is fixedly connected to the upper end of the positioning rod 24, and a conical groove 23 corresponding to the conical block 22 is opened at the lower end of the stirring rod 7, and the conical block 22 is inserted into the conical groove 23.

[0030] It should be noted that the stability of the stirring rod 7 during rotation can be improved by the cooperation of the fixing frame 8, the conical block 22, the positioning rod 24 and the conical groove 23. Furthermore, the cooperation of the conical block 22 and the conical groove 23 allows the stirring rod 7 to be removed from the mixing tank 3 after the first sealing cover 15 is removed.

[0031] In an optional embodiment: each of the multiple mixing tanks 3 is connected to a feed pipe 19, the feed pipe 19 extends to the outside of the housing 1, one end of the feed pipe 19 is connected to a feed hopper 21, and a second sealing valve 20 is provided on the feed pipe 19.

[0032] In an optional embodiment: a second sealing cover 18 is fixedly installed on the top of the housing 1, and the water inlet pipe 13 passes through the second sealing cover 18.

[0033] It should be noted that the second sealing cover 18 can be used to protect the drive gear 6 and the driven gear 12, preventing foreign objects from falling between the drive gear 6 and the driven gear 12 and affecting the transmission of the drive gear 6 to the driven gear 12.

[0034] In practical use, the raw materials for preparing cell culture medium are poured into the mixing tank 3 through the feed hopper 21 and feed pipe 19. The drive motor 4 is started, and the output shaft of the drive motor 4 rotates, driving the rotating rod 5 to rotate. When the rotating rod 5 rotates, it drives the drive gear 6 to rotate. When the drive gear 6 rotates, it drives multiple sets of driven gears 12 to rotate. The multiple sets of rotating driven gears 12 drive the stirring rod 7 to rotate. The rotation of the stirring rod 7 stirs and mixes the raw materials for cell culture medium in the mixing tank 3, thereby enabling the preparation of various cell culture mediums. This saves the preparation time for various cell culture mediums and improves the efficiency of preparing various cell culture mediums. After the cell culture medium is prepared, the first sealing valve 17 is opened, and the cell culture medium in the mixing tank 3 can be discharged and collected through the discharge pipe 16.

[0035] After the cell culture medium is prepared, water is supplied to the inlet pipe 13 through the water supply equipment. The water delivered to the inlet pipe 13 passes through the ring pipe 9 and is discharged into the mixing tank 3 through the nozzle 10. The drive motor 4 drives the rotating rod 5 to rotate the drive gear 6, which in turn drives the driven gear 12 and the stirring rod 7 to rotate. When the stirring rod 7 rotates, it drives the cleaning brush 14 to clean the inside of the mixing tank 3, which can prevent cell culture medium from remaining in the mixing tank 3. After cleaning the inside of the mixing tank 3, the first sealing valve 17 is opened to drain the cleaning liquid from the mixing tank 3. The ultraviolet sterilization lamp 11 is then activated to sterilize and disinfect the inside of the mixing tank 3, which can reduce the number of microorganisms inside the mixing tank 3 and reduce the risk of contamination.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
