[0002] In order to guarantee the healthy growth of infants, people often choose milk powder to feed infants, but when preparing milk, many milk powders need long time human shaking to make it fully dissolved in water. Milk shaker can quickly make milk powder and water fully mixed, save the time required for dissolving milk powder while avoiding the inconvenience of manual operation, and is welcomed by more and more families.

[0003] Traditional milk shaker mostly has low speed, which leads to still long time required for completing milk shaking process, and cannot effectively prevent milk powder from caking, hanging wall and other problems. In order to speed up milk shaking speed and improve milk shaking effect, increasing the running speed of milk shaking frame is a commonly used method, but this method will increase the centrifugal force generated when the milk shaking frame rotates, and intensify the shaking and vibration of the milk shaker, leading to unstable operation of the milk shaker, and even causing the milk shaker to tip over or the feeding bottle to fly out. In order to avoid this situation, a clamping mechanism capable of providing greater clamping force is needed to reliably clamp the feeding bottle. The milk shaker with clamping mechanism in the prior art mostly uses plastic spring sheet to clamp the feeding bottle, which has insufficient clamping force and poor adaptability to different specifications of feeding bottles; for example, the utility model patent with publication number CN217565804U uses torsional spring as elastic element, and the torsional spring is difficult to provide greater clamping force compared with spring, which cannot meet the requirements of high-speed milk shaker on clamping force, in addition, the torsional spring has poor buffer and shock absorption performance, and the elastic force of the torsional spring is nonlinear and affected by many factors, which is difficult to provide stable clamping force, and may lead to poor clamping effect.

[0032] Some embodiments of the present patent will be described in detail below with reference to the accompanying drawings. The features in the following embodiments can be combined with each other without conflict.

[0033] As Figures 1-7The utility model provides a high -speed milk rocker, including the rotating frame 1 for placing the feeding bottle, rotating frame 1 includes frame body 2 and the multiple clamping mechanism 3 of setting on frame body 2, clamping mechanism 3 has clamping arm 4 and cylindrical spring 5, clamping arm 4 has first end 6 and second end 7. High -speed milk rocker runs, and the rotating speed of rotating frame 1 is set to not less than 400r / min to satisfy the requirement of milk shaking effect. First end 6 is pivoted to frame body 1 through pivot 8, specifically, first end 6 has an axle hole 9, frame body 2 has the pivot hole 10 of adapting with pivot 8, pivot 8 passes through axle hole 9 and pivot hole 10, and pivot 8, axle hole 9 and pivot hole 10 are coaxial arrangement, to connect clamping arm 4 with rotating frame 1 cooperation, and pivot 8 and axle hole 9 form pivot pair, so that second end 7 can swing around pivot 8, the clearance fit of axle hole 9 and pivot 8 is preferred to reduce unnecessary friction, reduce the resistance when clamping arm 4 moves. The both ends of cylindrical spring 5 are respectively pressed on second end 7 and frame body 2, and the deformation direction of cylindrical spring 5 is basically horizontal, when feeding bottle is placed in rotating frame 1, second end 7 is pushed to swing outward, and then drives clamping arm 4 to compress cylindrical spring 5 and generates deformation, so that cylindrical spring 5 can exert force to second end 7 in the horizontal direction, and clamping arm 4 can clamp feeding bottle.

[0034] Specifically, cylindrical spring has the following advantages compared with torsional spring: the elastic force of cylindrical spring changes linearly, can better provide larger clamping force; better buffering and shock absorbing performance; simple and reliable structure, can provide stable clamping force. Therefore, by adopting cylindrical spring 5 as elastic element, compared with torsional spring as elastic element, the clamping performance of clamping mechanism 3 can be significantly improved, so that when the rotating speed of rotating frame 1 is increased to 1000r / min or even higher, clamping mechanism 3 can still reliably clamp feeding bottle, thereby ensuring the stable and reliable operation of high -speed milk rocker.

[0035] As Figures 1-3 And Figure 6As shown, two clamping mechanisms 3 are arranged in the vertical direction of the rotating frame 1, one clamping mechanism 3 is arranged at a higher position of the rotating frame 1 according to the size of the feeding bottle, so that when the feeding bottle is placed in the rotating frame 1, the second end 7 abuts against the upper part of the feeding bottle; the other clamping mechanism 3 is arranged at a lower position of the rotating frame 1 according to the size of the feeding bottle, so that when the feeding bottle is placed in the rotating frame 1, the second end 7 abuts against the lower part of the feeding bottle. In order to prevent the clamping arms 4 of the clamping mechanisms 3 from interfering with each other after installation, the distance between the two clamping mechanisms 3 at different heights should be sufficient, and the height dimension of the frame body 2 should be sufficient to accommodate the two clamping mechanisms 3. In an embodiment, the clamping mechanism 3 at the higher position is directly above the clamping mechanism 3 at the lower position, i.e. the two clamping mechanisms 3 are arranged opposite each other in the vertical direction of the rotating frame 1; in addition, the two clamping mechanisms 3 can also be arranged staggered. At least three clamping mechanisms 3 are uniformly distributed in the circumferential direction of the rotating frame 1, in an embodiment, four clamping mechanisms 3 are uniformly distributed in the circumferential direction of the rotating frame 1. By arranging the clamping mechanisms 3 in this way, the feeding bottle can obtain greater and multi-directional clamping force, ensuring reliable clamping of the feeding bottle when the rotating frame 1 rotates at high speed. According to actual needs, more clamping mechanisms 3 can be arranged in the vertical direction of the rotating frame 1 and in the circumferential direction, and these clamping mechanisms 3 can be arranged at any suitable position on the frame body 2.

[0036] As shown in Figures 1-7 , the cross section of the cylindrical spring 5 has a rectangular, flat, circular shape, etc., and the outer shape has a cylindrical, conical and disc shape, etc. In this embodiment, the cylindrical spring 5 is selected as a cylindrical spring with a circular cross section. The side wall of the frame body 2 has a positioning groove 11, one end of the cylindrical spring 5 is embedded in the positioning groove 11, and the positioning groove 11 should have sufficient depth to accommodate the cylindrical spring 5; the second end 7 has a positioning column 12 formed thereon, the positioning column 12 extends from the second end 7 towards the positioning groove 11, so as to be adapted to the deformation direction of the cylindrical spring 5, the other end of the cylindrical spring 5 is sleeved on the positioning column 12, and the radial dimension of the positioning column 12 should be smaller than the diameter of the cylindrical spring 5. The size of the clamping arm 4 and the position of the positioning groove 11 on the rotating frame 1 should be appropriately set, so that after the clamping mechanism 3 is installed, the second end 7 and the positioning groove 11 are substantially at the same height, so that after the cylindrical spring 5 is installed, the deformation direction is substantially horizontal.

[0037] As shown in Figure 2 , Figure 6 and Figure 7 , the side of the second end 7 facing the feeding bottle has a clamping surface 13. The feeding bottle generally has a cylindrical or approximately cylindrical shape, therefore the clamping surface 13 is configured as an arc surface adapted to the shape of the feeding bottle, so that when the feeding bottle is placed in the rotating frame 1, the clamping surface 13 is substantially attached to the feeding bottle, thereby enabling the second end 7 to better apply force to the feeding bottle, further improving the clamping effect.

[0038] As shown in Figures 3-7As shown in the drawings, the first end 6 has a limiting protrusion 14 extending downward, the frame wall of the rotating frame 1 has a limiting hole 15, the limiting hole 15 has a abutting surface 16 matched with the limiting protrusion 14; the limiting hole 15 is arranged on the rotating frame 1 at a position corresponding to the pivot hole 10 and above the positioning groove 11; after the clamping arm 4 is connected with the frame 1 through the pivot 8, the limiting protrusion 14 is inserted into the limiting hole 15. When there is no feeding bottle in the rotating frame 1, the restoring force of the cylindrical spring 5 makes the second end 7 swing inward, and the limiting protrusion 14 abuts against the abutting surface 16, thereby limiting the swing angle range of the second end 7, limiting the distance between the second end 7 and the positioning groove 11 to not more than the initial length of the cylindrical spring 5, so that the cylindrical spring 5 always has a restoring force and can be reliably pressed against the second end 7 and the positioning groove 11, avoiding the cylindrical spring 5 from being loosened from the second end 7 or the positioning groove 11.

[0039] As shown in the drawings, Figure 3 , Figure 5 and Figure 6 As shown in the drawings, the frame 2 is provided with a stop block 17, the stop block 17 is outside the first end 6 and has an outer shape matched with the first end 6, thereby preventing the first end 6 from being pulled out of the frame 2; there is a proper gap between the stop block 17 and the first end 6, preventing the first end 6 from rubbing against the stop block 17 to hinder the movement of the clamping arm 4.

[0040] The elastic coefficient of the cylindrical spring 5 is preferably 0.5-3 N / mm, using a spring within this range of elastic coefficient can provide sufficient clamping force for the clamping mechanism, while making the feeding bottle easy to be put into or taken out of the rotating frame 1. The initial length of the cylindrical spring 5 is preferably not less than 20 mm, so that the cylindrical spring 5 has a long enough compression stroke when the feeding bottle is put into the rotating frame 1, and the cylindrical spring 5 can generate sufficient clamping force, and the clamping mechanism 3 can be matched with feeding bottles of different specifications (diameter 50-75 mm), especially smaller specifications.

[0041] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which shall be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
