The hollow-out parts 310a are formed between the top end matching part 314 and the second matching part 312 and between the third matching part 313 and the first matching part 311, so that the sanitary dead angle of the mounting groove 310 can be further reduced, and the cleaning convenience of the stirring piece 3 is further improved on the basis that the stirring piece 3 and the rotating shaft 2 have enough connection strength.

In a specific embodiment, as shown in fig. 2 and 6, the liquid heating container further includes a release preventing member 4, where the release preventing member 4 is sleeved on the rotating shaft 2, and the release preventing member 4 is provided with a protruding portion 41, where the protruding portion 41 is used to limit the axial movement of the third mating portion 313 along the rotating shaft 2.

As shown in fig. 7, when the stirring member 3 has a moving tendency along the axial direction of the rotating shaft 2 (for example, the kettle body 1 is inclined as a whole due to pouring of water by a user, or the stirring member 3 is gradually separated from the rotating shaft 2 under the action of centrifugal force), the anti-falling member 4 is pressed by the inner wall of the mounting groove 310 and the outer wall of the rotating shaft 2, so that a resistance for preventing the stirring member 3 from moving along the axial direction of the rotating shaft 2 is generated, thereby limiting the relative movement of the stirring member 3 and the rotating shaft 2 along the axial direction of the rotating shaft 2. Therefore, through setting up anticreep spare 3 can improve the connection stability of pivot 2 and stirring piece 3, reduced in the use of liquid heating container, the risk that stirring piece 3 drops from pivot 2.

When H1 is too small (e.g., less than 1 mm), if the stirring element 3 is in a connection state with the rotating shaft 2, the distance between the upper end of the third fitting portion 313 and the protruding portion 41 is too large, so that the protruding portion 41 cannot fit with the third fitting portion 313 well, and if the stirring element 3 has a moving tendency along the axial direction of the rotating shaft 2, the third fitting portion 313 will move up and down, which affects the connection stability of the stirring element 3 with the rotating shaft 2. Therefore, when the height H1 of the third fitting portion 313 is 1mm to 2.5mm, the stirring member 3 and the anti-falling member 4 can be fitted in place, the anti-falling member 4 can play an anti-falling role, and the connection stability between the stirring member 3 and the rotating shaft 2 is also ensured.

In a specific embodiment, as shown in fig. 6 and 8, the rotating shaft 2 is provided with a groove 21, at least part of the anti-falling member 4 is accommodated in the groove 21, a first gap L1 is formed between the inner wall of the anti-falling member 4 and the side wall of the groove 21, and the first gap L1 satisfies: l1 is more than or equal to 0.25mm and less than or equal to 0.35mm. Specifically, L1 may be 0.25mm, 0.3mm, 0.32mm, 0.35mm, and so forth.

The portion of the rotating shaft 2 matched with the mounting groove 310 is provided with a groove 21, and at least part of the anti-falling piece 4 is accommodated in the groove 21, namely, when the rotating shaft 2 is in a connection state with the mounting groove 310, the anti-falling piece 4 is positioned in the mounting groove 310. The anti-falling piece 4 is in clearance fit with the groove 21, so that friction resistance between the anti-falling piece 4 and the groove 21 can be reduced, the anti-falling piece 4 can be conveniently installed in the groove 21, and the anti-falling piece 4 can be conveniently detached from the groove 21 for replacement.

When L1 is too large (for example, greater than 0.25 mm), the distance between the inner wall of the anti-drop member 4 and the side wall of the groove 21 is too large, the anti-drop member 4 is easy to loose after being assembled, the stability is insufficient, and the installation of the stirring member 3 is inconvenient. When L1 is too small (e.g., less than 0.35 mm), the distance between the inner wall of the drop-out preventing member 4 and the side wall of the recess 21 is too small, and it is inconvenient to mount the drop-out preventing member 4 in the recess 21 or detach it from the recess 21. Therefore, when the distance between the first gap L1 is 0.25mm to 0.35mm, the loose preventing member 4 is not easy to loose in the use process, and the assembling and disassembling of the loose preventing member 4 and the groove 21 can be facilitated.

The above is only a preferred embodiment of the present utility model, and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
