When D3 is too small (e.g., less than 1 mm), the stirring vanes 22 are too thin, the structural strength is insufficient, and bending or breakage may occur after a long period of operation. Therefore, when the thickness D3 of the stirring vanes 22 is 1mm to 3mm, the manufacturing cost of the stirring bar 2 can be reduced while the structural strength of the stirring vanes 22 is enhanced.

In a specific embodiment, in a direction from the bottom of the rotating shaft 1 to the top of the rotating shaft 1, the first matching portion 211, the second matching portion 212, the third matching portion 213 and the top matching portion 214 are sequentially disposed, a hollow portion 210a is formed between the third matching portion 213 and the first matching portion 211, and a hollow portion 210a is formed between the top matching portion 214 and the second matching portion 212.

In this embodiment, as shown in fig. 5, the first matching portion 211, the second matching portion 212, the third matching portion 213 and the top matching portion 214 are sequentially disposed in the bottom of the rotating shaft 1 toward the top of the rotating shaft 1, and are respectively attached to the rotating shaft 1, and along the radial direction of the rotating shaft 1, the first matching portion 211 and the third matching portion 213 are located on the same side of the rotating shaft 1, the second matching portion 212 is located on the other side of the rotating shaft 1, and the three surround the rotating shaft 1 along the circumferential direction of the rotating shaft 1, so that the installation stability of the stirring element 2 and the rotating shaft 1 can be effectively improved, and the stirring element 2 is prevented from being inclined relative to the rotating shaft 1. As shown in fig. 8, hollow portions 210a are formed between the third matching portion 213 and the first matching portion 211, and between the top matching portion 214 and the second matching portion 212, so that the hygienic dead angle of the accommodating groove 210 can be further reduced, and the cleaning convenience of the stirring part 2 is further improved on the basis that the stirring part 2 and the rotating shaft 1 have sufficient connection strength.

In a specific embodiment, as shown in fig. 5, the rotating shaft 1 is provided with a step portion 12, at least a part of the first matching portion 211 is accommodated in the step portion 12, and a second gap L2 is formed between an inner wall of the first matching portion 211 and a side wall of the step portion 12.

In this embodiment, when the stirring bar 2 is connected to the rotating shaft 1, at least a part of the bottom wall of the first fitting portion 211 can abut against the bottom wall of the stepped portion 12, so as to improve the stability of the stirring bar 2. And the inner wall of the first matching part 211 is in clearance fit with the side wall of the step part 12, so that the friction resistance between the inner wall and the side wall can be reduced, and the stirring piece 2 and the rotating shaft 1 can be assembled and disassembled conveniently.

Specifically, as shown in fig. 5, the distance of the second gap L2 satisfies: l2 is more than or equal to 0.05mm and less than or equal to 0.15mm. Specifically, L2 may be 0.05mm, 0.1mm, 0.12mm, 0.15mm.

In this embodiment, when the distance of second clearance L2 is too big (for example, be greater than 0.15 mm), the junction of first cooperation portion 211 after the assembly and step portion 12 takes place to become flexible easily, and stability is not enough, leads to stirring 2 to take place the slope for pivot 1, can lead to stirring 2 and pivot 1 to take place to drop when serious. When the distance of the second gap L2 is too small (for example, less than 0.05 mm), friction between the rotating shaft 1 and the stirring part 2 during assembling and disassembling can be increased, so that the first matching portion 211 and the step portion 12 are seriously worn, which is not beneficial to assembling and disassembling the rotating shaft 1 and the stirring part 2. Therefore, when the distance of the second clearance L2 is 0.05 mm-0.15 mm, the clearance fit between the stirring piece 2 and the rotating shaft 1 can be realized, the assembly and the disassembly are convenient, the stirring piece 2 can be prevented from inclining relative to the rotating shaft, and the falling off is avoided.

In a specific embodiment, as shown in fig. 3, the rotating shaft 1 is provided with a connecting portion 13, the connecting portion 13 includes a first arc surface 131 and a first plane 132, as shown in fig. 8, the second matching portion 212 includes a second arc surface 212a, the second arc surface 212a is matched with the first arc surface 131, the third matching portion 213 includes a second plane 213a, and the second plane 213a is matched with the first plane 132.

In this embodiment, when installing stirring piece 2 in pivot 1, connecting portion 13 gets into in the holding tank 210, as shown in fig. 5 and 8, at this moment, second cooperation portion 212 and third cooperation portion 213 all cup joint the outer wall at connecting portion 12, and second arc surface 212a closely laminates with first arc surface 131, second plane 213a closely laminates with first plane 132, can reduce the fit-up gap of stirring piece 2 and pivot 1, make stirring piece 2 fix on pivot 1, ensure that can not take place relative rotation between stirring piece 2 and the pivot 1, and pivot 1 can drive stirring piece 2 synchronous rotation.

In one specific embodiment, as shown in FIG. 5, the tip mating section 214 abuts an end of the connecting section 13.

In this embodiment, when the stirring part 2 is connected to the rotating shaft 1, the top end engaging portion 214 can restrict the stirring part 2 from continuing to move downward along the axial direction X of the rotating shaft 1, and the top end engaging portion 214 abuts against the top end of the connecting portion 13, so that the connection stability between the stirring part 2 and the rotating shaft 1 can be improved, and the stirring shaft 2 is prevented from being inclined with respect to the rotating shaft 1.

As shown in fig. 9, the height difference H2 between the bottom of the top end fitting portion 214 and the bottom of the second fitting portion 212 satisfies: h2 is not less than 6mm and not more than 8mm, and should not be too large or too small, specifically, 6mm, 6.5mm, 7mm, 8mm, etc.

When H2 is too large (for example, larger than 8 mm), the height of the connecting portion 13 engaged with the top end engaging portion 214 and the second engaging portion 212 is too large, stability is insufficient, and the connecting portion 13 is easily shaken during the rotation of the rotating shaft 1. When H2 is too small (for example, less than 6 mm), the height dimension of the connecting portion 13 that engages with the tip end engaging portion 214 and the second engaging portion 212 is too small, resulting in too small a connecting area of the stirring bar 2 and the rotating shaft 1, insufficient stability, and the stirring bar 2 is liable to be inclined with respect to the rotating shaft 1. Therefore, when the height difference H2 between the bottom of the tip end engagement portion 214 and the bottom of the second engagement portion 212 is 6mm to 8mm, the stability of the stirrer 2 and the rotating shaft 1 can be ensured.

In a specific embodiment, the liquid heating container further includes a retaining member 3, as shown in fig. 1, the retaining member 3 is sleeved on the rotating shaft 1, the retaining member 3 is used for limiting the stirring member 2 to move along the axial direction X of the rotating shaft 1 relative to the rotating shaft 1, as shown in fig. 3 and 4, a groove 11 is formed in the rotating shaft 1, and at least a portion of the retaining member 3 is accommodated in the groove 11.

In this embodiment, the groove 11 is disposed at the matching portion of the rotating shaft 1 and the receiving groove 210, and at least a portion of the anti-separation element 3 is received in the groove 11, that is, when the rotating shaft 1 and the receiving groove 210 are in a connection state, the anti-separation element 3 is located in the receiving groove 210. Adopt this kind of structure, when stirring 2 has the trend of moving along the axial X of pivot 1 (for example the user falls water and leads to the whole slope that takes place of kettle body 5, or stirring 2 breaks away from pivot 1 gradually under the effect of centrifugal force), anticreep piece 3 can be extruded by the inner wall of holding tank 210 and the outer wall of pivot 1, produces the resistance that hinders stirring 2 along the axial X motion of pivot 1 to restriction stirring 2 and pivot 1 along the relative motion of the axial X of pivot 1. Therefore, through setting up anticreep piece 3, can improve pivot 1 and stirring 2 connection stability, reduced in liquid heating container's use, the risk that stirring 2 drops from pivot 1.

Anticreep piece 3 in this embodiment adopts the silica gel material, has certain elasticity, can restrict stirring 2 and pivot 1 along the axial X's of pivot 1 relative motion, nevertheless can not influence the installation and the dismantlement of stirring 2 and pivot 1. In a specific embodiment, as shown in fig. 4, a first gap L1 is formed between the inner wall of the retaining member 3 and the side wall of the groove 11.

In this embodiment, be clearance fit between anticreep piece 3 and the recess 11, can reduce the frictional resistance between the two, be convenient for install anticreep piece 3 in recess 11, also be convenient for dismantle anticreep piece 3 from recess 11 and get off and trade newly. The distance of the first gap L1 satisfies the condition that L1 is not less than 0.8mm and not more than 0.4mm, and should not be too large or too small, and specifically may be 0.4mm, 0.5mm, 0.7mm, 0.8mm, and so on.

When L1 is too big (for example, greater than 0.8 mm), the distance between the inner wall of anticreep piece 3 and the lateral wall of recess 11 is too big, and anticreep piece 3 takes place to become flexible after the assembly easily, and stability is not enough, also is not convenient for the installation of stirring piece 2. When L1 is too small (e.g., less than 0.4 mm), the distance between the inner wall of retaining member 3 and the side wall of groove 11 is too small, and it is inconvenient to fit retaining member 3 into groove 11 or to remove retaining member 3 from groove 11. Therefore, when the distance of the first clearance L1 is 0.4 mm-0.8 mm, the anti-loosening piece 3 is not easy to loosen in the using process, and the anti-loosening piece 3 and the groove 11 can be assembled and disassembled conveniently. In a specific embodiment, as shown in fig. 5, the retaining member 3 includes a protrusion 31, the protrusion 31 is used to limit the movement of the first matching portion 211 along the axial direction X of the rotating shaft 1, as shown in fig. 6 and 7, the outer diameter of the protrusion 31 is D1, the inner diameter of the first matching portion 211 is D2, and 0.2mm ≦ D1-D2 ≦ 0.4mm. D1 to D2 may be specifically 0.2mm, 0.3mm, 0.35mm, 0.4mm or the like.

In this embodiment, at least a part of the protruding portion 31 protrudes from the groove 11, and when the first matching portion 211 moves along the axial direction X of the rotating shaft 1 to separate the stirring element 2 from the rotating shaft 1, the protruding portion of the protruding portion 31 protruding from the groove 11 can abut against the top wall of the first matching portion 211, so as to hinder the stirring element 2 from moving continuously along the axial direction X of the rotating shaft 1 relative to the rotating shaft 1, and achieve the purpose of preventing the stirring element 2 from falling off from the rotating shaft 1.

When D1-D2 are too large (e.g., greater than 0.4 mm), the protruding portion 31 protrudes from the recess 11 too much, in which case, during the assembly of the stirring part 2 with the rotating shaft 1, the contact area between the protruding portion 31 and the first matching portion 211 is too large, resulting in a large frictional resistance therebetween, which is inconvenient for mounting the stirring part 2 on the rotating shaft 1, and even resulting in that the stirring part 2 cannot be assembled in place. When D1-D2 are too small (e.g., less than 0.2 mm), the protruding portion 31 protrudes from the groove 11 too little, in this case, during the process of detaching the stirring element 2 from the rotating shaft 1, the contact area between the protruding portion 31 and the first matching portion 211 is too small (or not in contact), which results in too small friction resistance (or no friction resistance), and the anti-slip element 3 cannot play a role of blocking the axial X movement of the stirring element 2 along the rotating shaft 1, and cannot realize the anti-slip function of the anti-slip element 3.

Therefore, when D1-D2 is 0.2 mm-0.4 mm, the frictional resistance between the protruding portion 31 and the first matching portion 211 can be controlled within a proper range, thereby ensuring the smooth assembly of the stirring part 2 and the rotating shaft 1, and the anti-drop part 3 can block the axial movement X of the stirring part 2 along the rotating shaft 1.

Further, as shown in fig. 5, the height H1 of the first fitting portion 211 satisfies: h1 is more than or equal to 1mm and less than or equal to 2.5mm. Specifically, H1 may be 1mm, 1.5mm, 2mm, 2.5mm, and the like.

When H1 is too large (for example, greater than 2.5 mm), if stirring part 2 is in a connection state with rotating shaft 1, the upper end of first fitting portion 211 will interfere with protruding portion 31, resulting in that the fitting of anticreep piece 3 and stirring part 2 is not in place, and long-time use will result in that protruding portion 31 deforms, and then resulting in that anticreep piece 3 loses the anticreep effect. When H1 is too small (e.g., less than 1 mm), if the stirring element 2 is connected to the rotating shaft 1, the distance between the upper end of the first engaging portion 211 and the protruding portion 31 is too large, so that the protruding portion 31 cannot be engaged with the first engaging portion 211 well, and if the stirring element 2 tends to move along the axial direction X of the rotating shaft 1, the first engaging portion 211 may move up and down, which affects the connection stability between the stirring element 2 and the rotating shaft 1. Therefore, when the height H1 of the first matching portion 211 is 1 mm-2.5 mm, it is ensured that the stirring part 2 and the anti-falling part 3 can be matched in place, the anti-falling part 3 can play an anti-falling role, and the connection stability between the stirring part 2 and the rotating shaft 1 is ensured.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
