Description

Technical Field

[0001] This utility model relates to an elastic mixing tool for use on a handheld mixer. Background Technology

[0002] In the early days, the mixing heads of handheld mixers were mostly made of rigid materials, with relatively limited functions, making it difficult to adapt to the mixing needs of ingredients with different textures and viscosities.

[0003] As people pursue greater culinary diversity and convenience, flexible mixing heads have been increasingly developed and applied. The emergence of flexible mixing heads may stem from the exploration of more efficient and flexible mixing results.

[0004] Initially, the design of flexible stirring heads may have been relatively simple, and the materials and processes were also relatively limited. However, with continuous technological advancements, the quality of the materials has improved, such as the use of more durable, high-temperature resistant, and highly elastic synthetic materials.

[0005] During its development, the shape and structure of the flexible mixing head have been continuously optimized to meet different mixing tasks, such as beating eggs, mixing batter, and making sauces.

[0006] However, the existing elastic stirring head has poor elastic adjustment performance between the stirring head and the blade holder during the up-and-down movement. Utility Model Content

[0007] In order to overcome the shortcomings of the poor elasticity adjustment performance of the stirring head and blade of the current elastic stirring tool, this utility model provides an elastic stirring tool.

[0008] The technical solution of this utility model to solve its technical problem is as follows: an elastic stirring tool includes a blade, a connector at the upper end of the blade, the upper end of the blade being disposed within a connecting sleeve, the connecting sleeve being movably disposed within a connecting outer sleeve, a blade connected to the lower end of the blade, the blade being located within a head sleeve, an outer sleeve at the upper end of the head sleeve, a middle sleeve fixed within the outer sleeve; an inner sleeve at the lower end of the connecting outer sleeve, a cup at the upper part of the inner sleeve, a sleeve groove at the lower end of the cup, the upper end of the outer sleeve being movably disposed within the sleeve groove, and a return spring between the middle sleeve and the inner sleeve; the head sleeve, the outer sleeve, and the middle sleeve together form a head sleeve assembly, and the blade is rotatably connected to the head sleeve assembly.

[0009] A preferred embodiment of a tool holder push connecting sleeve structure includes an upper pushing part at the lower end of the connecting sleeve, a lower pushing part on the middle sleeve, a tool holder passing through the upper pushing part and the lower pushing part, and a retaining spring at the position between the upper pushing part and the lower pushing part on the tool holder. The retaining spring pushes the connecting outer sleeve downward, and the upper end of the outer sleeve retracts into the sleeve groove.

[0010] In a preferred embodiment, the upper pushing part is located on a protrusion in the middle of the connecting sleeve; the lower pushing part is located on a protruding edge of the inner sleeve.

[0011] In a preferred embodiment, the inner side of the outer sleeve is provided with a protruding edge, and a middle sleeve mounting groove is formed between the protruding edge and the outer sleeve, and the middle sleeve is snapped into the middle sleeve mounting groove.

[0012] To facilitate rotation between the headgear assembly and the cutter bar, an auxiliary rotating component is connected to the inner side of the headgear assembly. The auxiliary rotating component includes a bearing bracket, which is snapped onto the protruding edge. A sealing ring is provided at the head of the bearing bracket, and the cutter bar passes through the middle of the sealing ring. A bearing is installed and fixed between the bearing bracket and the cutter bar.

[0013] To facilitate sealing, the sealing ring is fitted onto the head of the auxiliary rotating component, and the sealing ring is provided with a sealing lip, the sealing lip extending out of the head cover.

[0014] In a preferred embodiment of the mounting method of the auxiliary rotating component, the auxiliary rotating component has a locking protrusion on its outer side, and the locking protrusion is engaged with the protruding edge.

[0015] To ensure a more secure fixation of the rotating component, a retainer is provided at the upper end of the component. The upper end of the retainer is secured to the protruding edge, and the lower end of the retainer abuts against the rotating component.

[0016] The middle sleeve is given a space for movement, and the lower end of the connecting sleeve is provided with an annular groove, into which the upper end of the cup of the inner sleeve is inserted.

[0017] A preferred method for connecting a rotating head and a connecting sleeve is provided, wherein the inner side of the connecting sleeve is further provided with a snap-fit ​​strip.

[0018] In use, the rotating head of the handheld mixer is mounted and fixed to the connector at the upper end of the blade in the connecting sleeve. Then it can be used. During use, when increased mixing force is needed, the tool can be pressed down. The head assembly, obstructed by the dough-like material, will be forced upwards, increasing the exposure of the blades and thus increasing the mixing force. As the head assembly rises, the entire outer shell shortens by retracting the outer sleeve into the sleeve groove.

[0019] The beneficial effects of this invention are as follows: 1. The length of the stirring head can be flexibly adjusted according to the size and depth of the container, ensuring effective stirring in various containers and improving the flexibility of use. 2. It can better handle stirring tasks in small amounts of food or narrow containers, increasing the applicable scenarios of the mixer. 3. The stirring head is hidden inside the head cover, which can reduce the risk of damage to the stirring head or personal injury caused by accidental collisions, and can protect the stirring head from external damage to a certain extent, extending its service life.
