[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment
[0023] Please refer to Figures 1-3 , this embodiment provides an online mixing device for culture medium filling, including a box body 1. An eccentric gear 4 is installed at one end of the top of the box body 1, and a driven gear 5 is installed at the other end of the top of the box body 1. The driven gear 5 meshes with the eccentric gear 4. A sleeve 6 is installed at the top of the driven gear 5, and a filling bottle 8 is clamped inside the sleeve 6. The bottom of the driven gear 5 is connected to a rotating shaft 12. A collar 13 is rotatably sleeved on the outer ring surface of the rotating shaft 12 up and down. Four springs 14 are evenly spaced on the outer ring surface of the collar 13. A round hole groove 101 is opened at one end of the top of the box body 1. One end of each spring 14 is fixedly connected to the inner side wall of the round hole groove 101. During the process of filling the culture medium into the filling bottle 8, the eccentric gear 4 drives the driven gear 5 to rotate. During the rotation of the driven gear 5, it will shake along an eccentric trajectory under the influence of the eccentric gear 4 and restore its position through the spring 14 during the shaking process, so that the driven gear 5 rotates in a state of uniform shaking, mixing the culture medium in the filling bottle 9, eliminating the need for manual shaking and reducing manual labor.
[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3 shown, a motor is installed inside the box body 1, and the rotating shaft of the motor is located at the top of the box body 1 and is connected to the bottom eccentric point of the eccentric gear 4. Two power switches 2 for controlling the motor switch are installed at one end of the top of one side surface of the box body 1. A speed regulator 3 is installed on the outer side surface of the box body 1 near the power switch 2. The speed regulator 3 is electrically connected to the motor. During the process of the motor driving the eccentric gear 4 to rotate, the speed of the motor can be adjusted by rotating the speed regulator 3, so that the speed of the eccentric gear 4 changes. At the same time, the speed of the driven gear 5 also changes accordingly. By changing the speed of the driven gear 5, the shaking amplitude of the filling bottle 8 is adjusted.
[0025] In this embodiment, as Figure 1 and Figure 2 shown, four support plates 7 are equidistantly installed on the outer ring surface at the bottom of the sleeve 6. One ends of the support plates 7 are respectively fixedly connected to the inner side wall at the top of the driven gear 5. The inner side surface of the sleeve 6 matches the size of the canned bottle 8, and a bolt is installed on one side surface at the top of the sleeve 6. After the bolt is tightened, it can extend to the inside of the sleeve 6. After the canned bottle 8 is inserted into the inside of the sleeve 6, the canned bottle 8 is squeezed and fixedly installed inside the sleeve 6 by tightening the bolt, preventing the canned bottle 8 from separating from the sleeve 6 due to shaking.
[0026] In this embodiment, as Figure 1 shown, a connecting pipe 10 is installed at the top of the canned bottle 8. The connecting pipe 10 is connected to one end of the feeding pipe of the culture medium canning equipment. An exhaust pipe 11 is installed at one end of the top of the canned bottle 8. The exhaust pipe 11 communicates with the inside of the canned bottle 8 and has a slender structure. During the canning process of the culture medium, the air in the culture medium in the canned bottle 8 is squeezed out through the exhaust pipe 11 by shaking the sleeve 6, preventing the canned culture medium from generating bubbles.
[0027] In this embodiment, as Figure 1 、 Figure 2 and Figure 3 shown, the rotating shaft 12 is perpendicular to the center of the inner side surface of the circular hole groove 101 and extends downward, and the bottom of the driven gear 5 at the top of the rotating shaft 12 fits against the top edge of the circular hole groove 101. During the rotation of the driven gear 5, it is avoided that the rotating shaft 12 supports the driven gear 5 and causes the spring 14 to be in a downward bent state.
[0028] Working principle: When the online mixing device is in use, first insert the canned bottle 8 into the sleeve 6 and tighten the bolt to fix the canned bottle 8. Then thread-connect the canned lid 9 to the top of the canned bottle 8. Then connect the connecting pipe 10 to the feeding pipe of the culture medium canning equipment. At this time, start the motor to drive the eccentric gear 4 to rotate. The eccentric gear 4 drives the driven gear 5 to rotate. During the rotation of the driven gear 5, it will shake along the eccentric trajectory under the influence of the eccentric gear 4 and restore its position through the spring 14 during the shaking process, so that the driven gear 5 rotates in a uniformly shaken state to mix the culture medium in the canned bottle 9, without the need for manual shaking, reducing manual labor. During the process of the motor driving the eccentric gear 4 to rotate, the speed of the motor can be adjusted by rotating the speed regulator 3, so that the speed of the eccentric gear 4 changes. At the same time, the speed of the driven gear 5 also changes accordingly. By changing the speed of the driven gear 5, the shaking amplitude of the canned bottle 8 is adjusted. During the canning process of the culture medium, the air in the culture medium in the canned bottle 8 is squeezed out through the exhaust pipe 11 by shaking the sleeve 6, preventing the canned culture medium from generating bubbles.
[0029] All the technical features in this embodiment can be freely combined according to actual needs.
[0030] The above embodiments are preferred implementation solutions of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present utility model.
