[0053] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0055] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0056] like Figure 1 As shown, the culture medium dissolving, heating and stirring device includes a body 1, on which an induction cooker 2 is arranged. The induction cooker 2 is used to heat the culture medium in a beaker (not shown in the figure), and the induction cooker 2 is powered on or off by controlling an induction cooker switch 20.

[0057] The machine body 1 is also provided with a main rod 3, on which a lifting rod 4 is provided so as to slide up and down. The lifting rod 4 is L-shaped, one end of the lifting rod 4 is connected to the main rod 3, and the other end of the lifting rod 4 is provided with a stirring mechanism 6. The stirring mechanism 6 includes a stirring motor 17, a stirring rod 18 provided at the output end of the stirring motor 17, and a plurality of stirring blades 19 provided at the lower end of the stirring rod 18. In order to improve the stirring efficiency, the stirring blade 19 extends in the vertical direction; in order to further improve the stirring efficiency, the lateral dimension of the stirring blade 19 gradually increases in the direction from top to bottom. In this example, the stirring blade 19 is triangular.

[0058] When the motor 17 is working, it drives the stirring rod 18 to rotate, and then drives the stirring blade 19 to rotate, and the stirring blade 19 stirs the culture medium. The motor 17 is controlled by the motor switch 21 to turn on and off.

[0059] The induction cooker 2 and the motor 17 are both connected to the power connector 22 and powered by the power connector 22. The power lines of the induction cooker 2 and the motor 17 have an overlapping portion, in which an emergency brake switch 16 is provided. By turning off the emergency brake switch 16, the induction cooker 2 and the motor 17 can be powered off at the same time, thereby improving safety.

[0060] The main rod 3 is a hollow rod, and the lifting rod 4 is sleeved in the main rod 3. The part of the lifting rod 4 located in the main rod 3 is called the inner end.

[0061] like Figure 5 As shown, a locking nut 9 is sleeved on the inner end of the lifting rod 4, and the locking nut 9 is slidably sleeved on the lifting rod 4. A fastening ring 12 is also sleeved on the lifting rod 4. The fastening ring 12 has a notch 14, so that the fastening ring 12 can be tightened and loosened, and the lifting rod 4 is tightly held when the fastening ring 12 is tightened.

[0062] The locking nut 9 is provided with an inclined surface 10 facing the outer circumference of the lifting rod 4. The inclined surface 10 is at a certain angle to the plumb line, and the horizontal distance between the upper end of the inclined surface 10 and the outer circumference of the lifting rod 4 is smaller than the horizontal distance between the lower end of the inclined surface 10 and the outer circumference of the lifting rod 4. A receiving cavity 11 is formed between the inclined surface 10 and the outer circumference of the lifting rod 4, and the fastening ring 12 is located in the receiving cavity 11. The locking nut 9 is also provided with an internal thread 13, specifically, the inclined surface 10 is provided with an internal thread 13, and the main rod 3 (see Figure 1 ) The upper end is provided with an external thread matching the internal thread 13, and the internal thread 13 is combined with the external thread on the upper end of the main rod 3. During the combination process, the accommodating cavity 11 is reduced, and the fastening ring 12 is squeezed and deformed by the inclined surface 10 of the locking nut 9 and the upper end of the main rod 3. After the fastening ring 12 is shrunk and deformed, it clamps the lifting rod 4, so that the lifting rod 4 and the main rod 3 are fastened together. To adjust the height of the lifting rod 4, loosen the locking nut 9, move the lifting rod 4 up or down, and tighten the locking nut 9 again.

[0063] In this example, the main function of the inclined surface 10 is to squeeze the fastening ring 12, that is, to squeeze the fastening ring 12 during the movement of the locking nut 9. The internal thread 13 is not necessarily provided on the inclined surface 10. The main function of the internal thread 13 is to combine with the main rod 3. As long as the internal thread 13 is provided on the locking nut 9, it will be sufficient.

[0064] In this example, the fastening ring 12 has a notch 14, so that the fastening ring 12 can be compressed and deformed when squeezed. In other embodiments, the notch 14 may not be provided, for example, the fastening ring 12 is elastic (made of elastic material), so that the fastening ring 12 can also be compressed and deformed when squeezed and the lifting rod 4 can be clamped.

[0065] like Figure 5 In order to slow down the moving speed of the lifting rod 4 during the process of adjusting the up and down position of the lifting rod 4, a damping member 15 is provided at the inner end of the lifting rod 4. The damping member 15 is a rubber pad, and the damping member 15 is pressed against the inner wall of the main rod 3. In this way, the moving speed of the lifting rod 4 can be slowed down and the safety can be improved. In other embodiments, the damping member 15 can also be arranged in other ways, such as sleeved on the outer periphery of the inner end of the lifting member 4, or arranged on the inner wall of the main rod 3. In short, the damping member 15 is arranged between the lifting rod 4 and the main rod 3.

[0066] In this example, the lifting rod 4 is hollow, and the power line of the stirring mechanism 6 is inserted into the lifting rod 4, that is, the power line of the stirring motor 17 is inserted into the lifting rod 4, so that the device structure is compact. The power line of the stirring motor 17 is further inserted into the main rod 3.

[0067] In order to prevent the lifting rod 4 from rotating during the ascending or descending process, an anti-rotation mechanism 5 is also provided in this embodiment. The anti-rotation mechanism 5 includes a raised portion 7 (see Figure 2 ) and concave area 8 (see Figure 3 ). Figure 2 for Figure 1 Middle AA section view, Figure 3 yes Figure 1 BB section view. Figure 2 The raised portion 7 is arranged on the inner wall of the main rod 3 and is a convex strip extending in the vertical direction. Figure 3 The concave portion 8 is provided on the outer wall of the lifting rod 4 and is a groove extending in the vertical direction. Figure 4 When the lifting rod 4 is sleeved in the main rod 3, the raised portion 7 is embedded in the recessed portion 8, so that when the lifting rod 4 rises or falls, it will not rotate, so that the stirring mechanism 6 connected to the lifting rod 4 (see Figure 1 ) will not shift in the horizontal direction, the stirring rod 18 and the stirring blade 19 arranged on the stirring rod 18 will not shift in the horizontal direction, and the stirring rod 18 and the beaker are accurately aligned to ensure the stirring effect.

[0068] In this example, both the raised portion 7 and the recessed portion 8 extend in the vertical direction, which is a preferred embodiment. In other embodiments, only the raised portion 7 may be extended in the vertical direction by a considerable length, or only the recessed portion 8 may be extended in the vertical direction by a considerable length, for example, the raised portion 7 is just a convex block, or the recessed portion 8 is just a small groove.

[0069] In summary, in this example, the culture medium in the beaker is heated by the induction cooker 2, and the culture medium is stirred by the stirring mechanism 6. The stirring mechanism 6 is raised and lowered by the cooperation of the lifting rod 4 and the main rod 3, so as to adapt to beakers of different heights. An anti-rotation mechanism 5 is also provided, and the anti-rotation mechanism 5 includes a raised portion 7 provided on the inner wall of the main rod 3 and a recessed portion 8 provided on the outer periphery of the lifting rod 4. The raised portion 7 is embedded in the recessed portion 8, so that the lifting rod 4 cannot rotate when it rises or falls, thereby ensuring that the stirring mechanism 6 does not shift in the horizontal direction, thereby ensuring that the stirring rod 18 is accurately positioned, ensuring the stirring effect, and improving the convenience of use.
