Description

Technical Field

[0001] The utility model specifically relates to an oscillating device for liquid biological culture medium. Background Art

[0002] An oscillating device for liquid biological culture medium is an oscillating and stirring device used for biological cell culture or microbial culture in a liquid culture medium. The main function of this device is to promote the full mixing and uniform distribution between the nutrients in the culture medium and biological cells through oscillation or stirring, so as to improve the growth rate and yield, and ensure that the microorganisms or cells in the culture medium can fully obtain oxygen and nutrients, guaranteeing the successful progress of the culture process.

[0003] However, most traditional oscillating devices for liquid biological culture medium use a single stirring mechanism to oscillate and stir the culture medium, so that uneven oscillation may occur during the oscillation process of the oscillating device, resulting in uneven deposition of the liquid or cells in the culture medium, affecting the accuracy and repeatability of the culture results. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and an oscillating device for liquid biological culture medium is proposed. Compared with most traditional oscillating devices for liquid biological culture medium, the oscillating device for liquid biological culture medium is provided with a fixed seat, on which a second push rod and a first push rod are connected. By the rotation of the first servo motor driving the rotating disk, the fixed seat is controlled to move back and forth on the first sliding rod, and then the culture medium main body on the fixed seat is oscillated reciprocally. Then, the second servo motor drives the stirring rod to mix and stir the liquid in the culture medium main body. The back-and-forth movement of the fixed seat makes the stirring position constantly adjusted. Through double stirring and oscillation, the device can mix and stir the liquid biological culture medium more evenly, thereby improving the mixing and stirring effect of the device.

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figures 1-5, a liquid biological culture medium oscillation device provided in this embodiment includes a base 1 and a rotating handle 27. A support rod 2 is fixedly connected to the front end of the upper surface of the base 1 on the side far from the box body 8. The upper end of the outer wall of the support rod 2 is fixedly connected to a controller 3, so that the user can conveniently control the device through the controller 3. A box body 8 is fixedly connected to one side of the upper surface of the base 1. A first servo motor 4 is fixedly connected to the middle of the upper surface of the base 1 on the side far from the box body 8. The output end of the first servo motor 4 is fixedly connected to a rotating disk 5. One side of the upper surface of the rotating disk 5 is rotatably connected to a first push rod 6. One end of the first push rod 6 far from the rotating disk 5 is hinged to a second push rod 7. One side of the upper surface of the box body 8 is hinged to a placement plate 9. The center of the upper surface of the placement plate 9 is fixedly connected to a second servo motor 11. The output end of the second servo motor 11 is fixedly connected to a stirring rod 12. Two first sliding rods 14 are fixedly connected to the lower ends of the inner walls on both sides of the box body 8. Two limit sliders 28 are slidably arranged in the middle of the outer walls of the first sliding rods 14. The upper surface of the limit slider 28 is fixedly connected to a fixing seat 16. The inner walls around the fixing seat 16 are respectively provided with a second sliding rod 21, a first bidirectional threaded rod 22 and a second bidirectional threaded rod 23. Both ends of the outer wall of the first bidirectional threaded rod 22 are threadedly engaged with a first clamping bracket 24. A clamping groove 25 is opened in the middle of the outer wall of one side of the first clamping bracket 24. Both ends of the outer wall of the second bidirectional threaded rod 23 are threadedly engaged with a second clamping bracket 26.

[0033] Compared with the existing liquid biological culture medium oscillation device, the liquid biological culture medium oscillation device of this embodiment is provided with a fixing seat 16. A second push rod 7 and a first push rod 6 are connected to the fixing seat 16. By the rotation of the first servo motor 4 driving the rotating disk 5, the reciprocating movement of the fixing seat 16 on the first sliding rod 14 is controlled, and then the culture medium main body 17 on the fixing seat 16 is oscillated reciprocally. Then, the liquid in the culture medium main body 17 is mixed and stirred by the second servo motor 11 driving the stirring rod 12. The reciprocating movement of the fixing seat 16 makes the stirring position constantly adjusted. Through double stirring and oscillation, the device can mix and stir the liquid biological culture medium more evenly, and then the mixing and stirring effect of the device is improved.

[0034] The second push rod 7 passes through the box body 8 and is fixedly connected to the fixed seat 16, so that the second push rod 7 can drive the fixed seat 16 to move reciprocally on the first slide rod 14. The outer walls of the front end and the rear end of the placement plate 9 are fixedly connected with cover plates 10. A pin 13 is arranged on one side of the upper surface of the box body 8 away from the placement plate 9, so that the user can fix the cover plate 10 on the box body 8 through the pin 13. Buffer pads 15 are fixedly connected to both sides of the outer wall of the first slide rod 14. By arranging the buffer pads 15, the fixed seat 16 is buffered. The middle of the upper surface of the fixed seat 16 is clamped and matched with the culture medium main body 17, so that the user can mix, oscillate and stir the culture medium main body 17 through this device. The middle of the inner walls around the fixed seat 16 are all provided with chutes 20. By arranging the chutes 20, the first clamping frame 24 and the second clamping frame 26 can adjust their positions on the fixed seat 16. Two limiting rings 18 are fixedly connected to the outer walls around the fixed seat 16. The upper ends of the outer walls of the limiting rings 18 are in threaded cooperation with limiting bolts 19. By arranging the limiting rings 18 and the limiting bolts 19, the positions of the first double-threaded screw rod 22 and the second double-threaded screw rod 23 after rotation are fixed.

[0035] When the oscillation device of this embodiment is in use, the first double-threaded screw rod 22 and the second double-threaded screw rod 23 can be rotated first by rotating the handle 27, so as to control the first clamping frame 24 and the second clamping frame 26 to move simultaneously towards the center of the fixed seat 16, and then clamp and fix the culture medium main body 17 on this device. Replace the suitable rotating disk 5 according to the size of the culture medium main body 17, so as to adjust the distance that the fixed seat 16 moves on the first slide rod 14 to avoid collision with the stirring rod 12. Cover the cover plate 10 and fix it with the pin 13, and then start the second servo motor 11 to rotate at a low speed so that the stirring rod 12 mixes and stirs the culture medium main body 17. Finally, rotate the first servo motor 4 at a low speed to drive the rotation of the rotating disk 5, so as to control the fixed seat 16 to move back and forth on the first slide rod 14, and then reciprocally oscillate the culture medium main body 17 on the fixed seat 16. The back-and-forth movement of the fixed seat 16 makes the position stirred by the stirring rod 12 constantly adjusted.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
