Description

Technical Field

[0001] This utility model relates to the field of thermostatic oscillator technology, and more specifically, to a thermostatic oscillator for cell culture. Background Technology

[0002] The key to cell growth is providing appropriate temperature and oxygen supply. A thermostatic shaker can control the culture temperature at around 37°C. At the same time, the thermostatic shaker can also promote cell metabolism and proliferation by vibrating and stirring the cells and culture medium, thereby achieving the purpose of cell culture. When the controller heats the liquid in the water bath of the incubator, the liquid in the water bath is basically still, which leads to uneven heating of the liquid, increases the energy consumption required for heating and affects efficiency.

[0003] According to patent publication number CN221877057U, a constant temperature shaker with cell culture function is disclosed, including a shaker body with a water bath chamber and a shaking disk for carrying materials. The shaking disk can oscillate back and forth in the water bath chamber. A stirring component is provided inside the water bath chamber and below the shaking disk. This structure can agitate the liquid in the water bath chamber by setting the stirring component at the bottom of the water bath chamber of the shaker body, so that the liquid is heated more evenly and the efficiency of water bath heating is improved.

[0004] However, in actual use, the temperature control effect of a constant temperature shaker is usually achieved by heating and then maintaining the temperature of the air in the sealed chamber. However, since the heating element is in a fixed position and the heat generation location is fixed, it is easy to cause uneven heating inside the sealed chamber, which affects the cell culture effect.

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.

[0028] As attached Figure 1-4 The present invention relates to a thermostatic shaker for cell culture, comprising a chassis 1, an organic cover 2 hinged to the top of the chassis 1, a shaker box 3 inside the chassis 1, a placement rack 4 fixedly mounted inside the shaker box 3, a shaker assembly at the bottom of the shaker box 3, an annular slide 5 at the top of the shaker box 3, the annular slide 5 being fixedly connected to the chassis 1, a slider 6 slidingly mounted on the front side of the annular slide 5, and a thermostatic assembly at the bottom of the slider 6.

[0029] In some embodiments, according to Figure 2 , 3 As shown, the constant temperature component includes an annular frame 7 fixed to the inner wall of the housing 1, an annular electric slide rail 8 fixedly provided on the top of the annular frame 7, a slide table 9 provided on the top of the annular electric slide rail 8, a connecting plate 10 fixedly provided on the top of the slide table 9, and a hot air blower 11 fixedly provided on the top of the connecting plate 10.

[0030] In some embodiments, according to Figure 3As shown, a hot air pipe 12 is provided through the output end of the hot air blower 11. One end of the hot air pipe 12 is connected to an arc-shaped exhaust shell 13. The arc-shaped exhaust shell 13 is fixedly connected to the slider 6. Multiple nozzles 14 are connected through the front side of the arc-shaped exhaust shell 13. The annular electric slide rail 8 enables the hot air discharged from the nozzles 14 to rotate around the outside of the culture container for heating and constant temperature treatment.

[0031] In some embodiments, according to Figure 2 , 4 As shown, the oscillation assembly includes a positioning plate 15 fixed to the bottom of the oscillation box 3. A swing rod 16 is fixedly provided at the bottom of the positioning plate 15. A rotating shaft 17 is fixedly provided at the bottom of the swing rod 16. An oscillation frame 18 is rotatably connected to the bottom of the rotating shaft 17. The rotating shaft 17 passes through the oscillation frame 18 and extends to the bottom of the oscillation frame 18. The rotation of the rotating shaft 17 causes the swing rod 16 to drive the positioning plate 15 to rotate eccentrically, thereby performing eccentric rotational motion on the culture container.

[0032] In some embodiments, according to Figure 2 , 4 As shown, an oscillating plate 19 is fixedly installed at the bottom of the oscillating frame 18, a stepper motor 20 is fixedly installed at the top of the oscillating plate 19, a reducer 21 is fixedly installed at the output end of the stepper motor 20, and the output end of the reducer 21 is fixedly connected to the rotating shaft 17.

[0033] In some embodiments, according to Figure 2 As shown, a vibrator 22 is fixedly mounted on the bottom of the vibrating plate 19, and multiple springs 23 are fixedly mounted on the bottom of the vibrating plate 19. All the multiple springs 23 are fixedly connected to the housing 1.

[0034] In some embodiments, according to Figure 2 As shown, each of the multiple springs 23 has a limiting post 24 on its inner side. The limiting post 24 is fixedly connected to the housing 1. The springs 23 can provide support and buffer for the entire vibrating plate 19, thereby ensuring that the vibrating machine 22 can work normally.

[0035] The working principle of this utility model is as follows: (refer to the appendix of the instruction manual) Figure 1-4 As shown, the culture container with built-in cells is first placed in the placement rack 4. Then, the stepper motor 20 is started and driven by the reducer 21 to rotate the rotating shaft 17. The rotating shaft 17 then drives the swing arm 16 to rotate. The swing arm 16 then drives the positioning plate 15 to rotate eccentrically. The positioning plate 15 then drives the entire shaking box 3 to rotate eccentrically, thereby making the culture container rotate eccentrically and shake it evenly.

[0036] At the same time, the vibrator 22 is started to drive the oscillation plate 19 to vibrate up and down. The oscillation plate 19 drives the spring 23 to extend and retract at the limit post 24, thereby driving the oscillation frame 18 and the oscillation box 3 to vibrate as a whole, thus cooperating with the stepper motor 20 to make the oscillation of the culture container more uniform and sufficient.

[0037] Then, the hot air blower 11 is started to exhaust hot air from the hot air pipe 12 to the arc-shaped exhaust shell 13 and then spray it out from the nozzle 14. At the same time, the annular electric slide rail 8 is started to drive the slide table 9 to rotate the connecting plate 10. The connecting plate 10 then drives the hot air blower 11 to rotate as a whole, so that the arc-shaped exhaust shell 13 drives the slider 6 to rotate at the annular slide 5. This allows the hot air blower 11 and the arc-shaped exhaust shell 13 to rotate and move to provide more uniform heating and constant temperature treatment for the culture container.

[0038] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
