[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] In order to solve the problem in the prior art that the submerged agitator is difficult to operate stably, the utility model provides a submerged agitator.

[0026] like Figure 1 As shown, the submersible agitator is used to stir the liquid in the accommodating chamber, and the submersible agitator includes a stirring component 10, a driving component 20 and a balancing component 30. The stirring component 10 includes a stirring shaft 11, and at least a portion of the stirring shaft 11 extends into the accommodating chamber; the driving component 20 is connected to the end of the stirring shaft 11 away from the liquid, and the driving component 20 is used to drive the stirring shaft 11 to rotate; the balancing component 30 is located outside the accommodating chamber, at least a portion of the balancing component 30 is supported between the driving component 20 and the accommodating chamber, and at least another portion of the balancing component 30 is sleeved on the stirring shaft 11, and the balancing component 30 can support the stirring shaft 11 in the radial direction of the stirring shaft 11.

[0027] Since the driving component 20 is connected to the stirring shaft 11, the stirring component 10 will be scaled after being stirred in the liquid for a long time, causing the stirring shaft 11 to rotate unbalanced. The balancing component 30 provides radial support for the stirring shaft 11, and the force points of the rotating parts in the stirring component 10 and the driving component 20 after scaling are transferred to the balancing component 30, offsetting the radial force of the dynamic imbalance after scaling, so that the mass axis of the agitator and the rotation axis are basically coincident. At the same time, the balancing component 30 can provide support between the driving component 20 and the accommodating cavity, further ensuring the safety and stability of the driving component 20 and the stirring component 10.

[0028] like Figure 1 As shown, the balancing assembly 30 includes a suspension 31 and a balancing part 32.

[0029] like Figure 1As shown, the stirring shaft 11 is located on the central axis of the suspension 31, and the suspension 31 is gradually expanded from the drive assembly 20 toward the accommodating cavity. This is conducive to the basic coincidence of the mass axis of the stirrer and the rotation axis, reducing the risk of radial unbalanced force destroying stable operation. At the same time, the stability of the structure outside the accommodating cavity is improved to prevent the driving assembly 20 from tipping over.

[0030] like Figure 1 As shown, the suspension 31 includes a top plate 311, a bottom plate 312 and at least three spaced support rods 313, the top plate 311 is connected to the drive assembly 20, and the center of the top plate 311 has a through hole for connecting the stirring shaft 11 to the drive assembly 20; one end of the support rod 313 is connected to the top plate 311; the other end of the support rod 313 is connected to the bottom plate 312, one side of the bottom plate 312 is connected to the balancing part 32, the other side of the bottom plate 312 is connected to the accommodating cavity, and the bottom plate 312 has a central hole for the stirring shaft 11 to pass through. By arranging the top plate 311 and the bottom plate 312 to be connected to the drive assembly 20 and the accommodating cavity respectively, the connection stability is improved, and the multiple support rods 313 further stabilize the support.

[0031] like Figure 1 As shown, a plurality of support rods 313 are arranged at equal intervals along the circumference of the suspension 31, which is beneficial for the mass axis of the agitator to basically coincide with the rotation axis, while improving the stability of the support.
