Description

Technical Field

[0001] The utility model relates to the field of stirring paddles, in particular to a fixing structure for a disposable stirring paddle. Background Art

[0002] A disposable stirring paddle is a tool used for stirring. The structure and blade shape of the paddle determine the overall stirring form of the liquid in the kettle. The disposable stirring paddle is usually made of environmentally friendly plastic or stainless steel, with a compact structure and exquisite design. It avoids the problem of traditional agitators to prevent cross contamination and complicated cleaning. Users only need to insert it into the mixture for quick and even stirring, and discard it after completing the task, eliminating the tedious cleaning steps.

[0003] The fixed structure of a disposable stirring paddle determines its service life and working efficiency. A stable fixed structure can ensure that the blades will not loosen or fall off when rotating at high speed, thereby ensuring the continuity and stability of the stirring process. If the blades are unstable, it will not only affect the stirring effect, but may even cause damage to the equipment and increase maintenance costs. For this reason, we propose a fixed structure for disposable stirring paddles. Utility Model Content

[0024] Specifically, Figure 4 As shown, the circular bayonet 5 includes a clamp head, a column body and a clamp joint at the bottom from top to bottom. The diameter of the clamp head is larger than the diameter of the slot 4 so that it can be clamped on the outside of the slot 4. The diameter of the column body is adapted to the size of the slot 4, making the structure more stable.

[0025] The card connector includes two movable bars separated from each other on both sides, and a gap is provided between the two movable bars. The gap is used to allow the two movable bars to be retracted slightly inward when the circular card pin 5 is pulled out, so as to facilitate passing through the card slot 4. Figure 4 As shown, in order to facilitate the movable bar to be stuck outside the slot 4, a plane perpendicular to the slot 4 is provided on one side of the movable bar close to the slot 4.

[0026] It can be understood that a through hole 6 is provided on the inner wall of the shaft sleeve 1 , the stirring shaft is driven to rotate by the motor, and the shaft sleeve 1 is passed through the through hole 6 and is placed on the outside of the stirring shaft.

[0027] Among them, Figure 5 As shown, the number of the blades 3 is not less than three, and the combined coverage of the three blades 3 on the outer side of the sleeve 1 is circular, so that a large amount of fluid in the container can be driven to flow during stirring, thereby improving the stirring efficiency.

[0028] The outer wall of the sleeve 1 is clamped with a fixed bayonet 8, which runs transversely through the inner side of the sleeve 1 and has two ends extending from the outer side of the sleeve 1.
