DETAILED DESCRIPTION

[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the following will combine the drawings in the embodiments of the present application to clearly and completely describe the technical scheme in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0026] As Figures 1-5 shown, a stirring hook 100 is connected with a connecting shaft 200 of a chef machine, and the connecting shaft 200 is driven to rotate by a driving mechanism such as a motor and a gear assembly inside the chef machine, thereby driving the stirring hook 100 to rotate and achieving the stirring of flour and other food in a face barrel. The stirring hook 100 is a dough hook, a stirring rod or a whisk, etc. which can realize the stirring function. It can be understood that the specific structure of the stirring part 2 is not limited and can be a paddle, a hook or a whisk, etc.

[0027] The stirring hook 100 of the embodiment comprises a hook base 1 and a stirring part 2, the stirring part 2 is fixedly installed at the lower part of the hook base 1, and the hook base 1 and the stirring part 2 can be fixedly connected by welding or pressure casting integral molding process, etc. A bushing 3 is fixedly embedded in the hook base 1, that is, the bushing 3 is fixed in the hook base 1 and cannot be directly taken out from the hook base 1. The bushing 3 is provided with a clamping groove 311, and the connecting shaft 200 of the chef machine is detachably connected with the clamping groove 311. It can be understood that in the working state of the chef machine, the connecting shaft 200 is clamped in the clamping groove 311, so that the whole stirring hook 100 is connected with the connecting shaft 200 and does not contact with the hook base 1. The material of the bushing 311 is POP plastic or POM plastic. Since the bushing 3 is a non-metal material and the connecting shaft 200 is directly connected with the bushing 300, the contact connection between the stirring hook 100 and the connecting shaft 200 is not metal and metal, and when the chef machine is working, there is no metal and metal friction, thereby avoiding the generation of metal black powder.

[0028] Preferably, the material of the bushing 311 is POP plastic. POP is a high-performance thermoplastic elastomer with strong toughness and durability, which can improve the softness of the finished product and is widely used in food packaging field. The bushing is made of POP plastic material, and the rotating shaft 200 is not easy to produce hard friction with the bushing 3 during rotation.

[0029] Further, as Figure 2 and Figure 4 shown, the hook base 1 is columnar, which can be cylindrical or irregular columnar. The hook base 1 has an opening at the top and has a containing cavity 12 inside, the opening is in communication with the containing cavity 12, and the bushing 3 is fixedly embedded in the containing cavity 12, so that the connecting shaft 200 extends into the bushing 3 from the opening. The bushing 3 is fixedly embedded in the containing cavity 12, on the one hand, it enhances the connection strength between the connecting shaft 200 and the hook base 1, and avoids the bushing 3 from being separated from the hook base 1 due to the increase of the rotating speed of the connecting shaft 200 during stirring; on the other hand, the hook base 1 does not need to be provided with a clamping groove, and the whole connecting shaft 200 is also embedded in the hook base 1, that is, even if the stirring is rotated for a long time, the connecting shaft 200 always remains connected with the bushing 3, and the connection relationship between the bushing 3 and the side wall of the hook base 1 will not be generated, which further avoids the generation of black powder.

[0030] Further, as shown in Figure 2 and Figure 5 The bushing 3 includes a connecting seat 31 and a backing plate 32. The connecting seat 31 is arranged on the bottom surface of the backing plate 32. A through hole 321 is arranged in the middle of the backing plate 32 and communicates with the clamping groove 311, so that the connecting shaft 200 can pass through the through hole 321 and slide into the clamping groove 311, thereby realizing the connection between the connecting shaft 200 and the stirring hook 100. The outer wall of the connecting seat 31 is provided with a protrusion 132, and the clamping groove 311 penetrates the protrusion 132. The side wall of the accommodating cavity 12 is provided with an inwardly recessed mounting groove 121, and the protrusion 132 is clamped in the mounting groove 121, so that the bushing 3 can be better embedded in the accommodating cavity 12 of the hook seat 1 and is not easy to fall off. In the embodiment, the connecting seat 31 is arranged in a columnar shape, which is convenient for adapting to the hook seat 1. The protrusion 132 protrudes from the outer wall of the columnar connecting seat. The hook seat 1 is arranged in a columnar shape with a large upper part and a small lower part. The cross section of the hook seat 1 is trapezoidal, and the upper base width W1 is greater than the lower base width W2, so that the upper part of the hook seat 1 can accommodate the protrusion 132, and the lower part can adapt to the area of the connecting seat 31 where the protrusion 132 is not arranged. The bushing 3 is in interference fit with the hook seat 1, and the bushing 3 is more firmly embedded in the hook seat 1.

[0031] In the embodiment, the clamping groove 311 includes a vertical guide groove 3111 and a limiting groove 3112. One end of the vertical guide groove 3111 communicates with the through hole 321, and the other end communicates with the limiting groove 3112. The connecting shaft 200 is clamped in the limiting groove 3112. When installing the stirring hook 100, the connecting shaft 200 is inserted into the through hole 321, and the stirring hook 100 is rotated to clamp the connecting shaft 200 in the limiting groove 3112, thereby completing the installation of the stirring hook 100. When disassembling the stirring hook 100, the stirring hook 100 is lifted up and down, and then the stirring hook 100 is reversely rotated, so that the connecting shaft 200 slides from the limiting groove 3112 to the vertical guide groove 3111, and finally separates from the through hole 321.

[0032] Specifically, in order to further strengthen the fixed connection between the bushing 3 and the hook seat 1 and avoid the generation of a gap between the bushing 3 and the hook seat 1 under the condition of using a large rotating speed, thereby affecting the stirring intensity of the stirring part 2, the hook seat 1 is provided with a stepped surface 11 at the opening in the embodiment. The backing plate 32 is clamped on the stepped surface 11, and the fixing member 4 penetrates the backing plate 32 or the side wall of the connecting seat 1 and is fixed with the hook seat 1. In the embodiment, the fixing member 4 is a part that can realize the strengthened fixation of the bushing 3 and the connecting seat 1, such as a screw. The installation position of the fixing member 4 is not limited. It can penetrate the backing plate 32 and be fixed on the inner wall surface of the hook seat 1, or it can penetrate the outer side wall of the hook seat 1 and be fixed on the outer side wall of the connecting seat 1. Preferably, in the embodiment, in order to facilitate assembly, the fixing member 4 penetrates the backing plate 32 and is fixed on the inner wall surface of the hook seat 1.

[0033] More specifically, in the embodiment, the side wall of the hook seat accommodating cavity 12 is inwardly recessed to form a mounting groove 121, and the non-recessed area forms a protruding portion 122 adjacent to the mounting groove 121, and a first positioning hole 1221 is arranged at the top position of the protruding portion 122, that is, the first positioning hole 1221 is adjacent to the stepped surface 11, and correspondingly, the second positioning hole 322 is arranged on the lining plate 32, and the fixing member 4 is fixed in the second positioning hole 322 after passing through the first positioning hole 1221. When the bushing 3 is installed, the protrusion 132 on the connecting seat 31 is aligned with the mounting groove 121, the bushing 3 is completely pressed into the hook seat accommodating cavity 12, and then the fixing member 4 is fixed by passing through the first positioning hole 1221, and the entire bushing 3 is more stably embedded in the hook seat 1, and the opening of the hook seat 1 is blocked by the lining plate 32, the lining plate 32 is completely embedded in the hook seat 1, which is convenient for users to clean and is not easy to drop dirt and impurities into the accommodating cavity 12.

[0034] In the embodiment, the first positioning hole 1221 is provided with at least one, and the specific number is adjusted according to the structure of the connecting shaft 200. If the clamping groove 311 is provided with only one, the volume of the protruding portion 122 is relatively large, at this time, the first positioning hole 1221 can be arranged at the middle position of the entire protruding portion 122, or the first positioning hole 1221 can be arranged at both ends of the protruding portion 122, and the specific number of the first positioning hole 1221 is adjusted according to the volume of the hook seat 1. If the clamping groove 311 is provided with two, the mounting groove 121 is also provided with two, at this time, two symmetrical protruding portions 122 are formed, and the first positioning hole 1221 is arranged on both of the two protruding portions 122, so that the entire bushing 3 is more stably installed.
