[0020] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1-Figure 3 As shown, the embodiment of the present invention provides a microorganism cultivation device, comprising:

[0022] Erlenmeyer flask 1;

[0023] Mixing and stirring assembly; the mixing and stirring assembly includes a mounting frame 5 that can be mounted on the conical flask 1. The mounting frame 5 is not sealed on the upper end of the conical flask 1. A mounting cylinder 3 is fixed to the bottom of the mounting frame 5. The mounting cylinder 3 cannot shake in the conical flask 1, thereby ensuring the stability of the mounting frame 5; three support rods 6 are fixedly connected to the bottom of the mounting frame 5, and the support rods 6 are connected to the mounting cylinder 3.

[0024] The mounting tube 3 slides against the inner wall of the conical flask 1, and a plurality of arc buckles 4 are fixed on the mounting tube 3. The arc buckles 4 are buckled on the bottle mouth of the conical flask 1, and the mounting tube 3 can be fixed on the conical flask 1 through the arc buckles 4; in order to increase the stability between the arc buckles 4 and the conical flask 1, the arc buckles 4 are made of plastic, and a rubber pad is provided on the side of the arc buckle 4 that abuts against the conical flask 1, so as to increase the stability between the arc buckles 4 and the conical flask 1.

[0025] A motor 2 is mounted on the mounting frame 5, and an output end of the motor 2 is fixedly connected to a shaft 8, on which a propeller 10 is fixed. A guide tube 9 is provided on the outside of the propeller 10, and the propeller 10 does not contact the guide tube 9. The propeller 10 and the guide tube 9 are coaxially arranged. Three pull rods 7 are fixed on the guide tube 9, and the pull rods 7 are fixedly connected to the bottom of the mounting frame 5.

[0026] When in use, the culture solution to be mixed is added into the conical flask 1, and then the arc buckle 4 is buckled on the conical flask 1, and then the motor 2 is energized. The motor 2 drives the shaft 8 to rotate, and the rotation of the shaft 8 drives the propeller 10 to rotate. The rotation of the propeller 10 can transport the culture solution upward through the guide tube 9. In this way, the continuous rotation of the propeller 10 can realize the circulation of the culture solution in the conical flask 1, so that the culture solution can be quickly mixed;

[0027] After the mixing is completed, the arc buckle 4 is removed from the conical flask 1, and the culture solution in another conical flask 1 can be mixed;

[0028] The utility model has a simple and compact structure and can be used with a conical flask 1. It is suitable for mixing a small amount of culture medium and avoids the disadvantage of the prior art that the culture medium needs to be transferred after mixing. The mixing and stirring component can be customized according to the model of the conical flask 1.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
