Without more limitations, the element defined by the statement "includes one" does not exclude the presence of another identical element in the process, method, article or device including the element. "Multiple" means greater than or equal to two.

[0031] As shown in Figure 1 The utility model embodiment provides a kind of stirring assembly 10 applied to cooking machine, which is mainly used to stir and stir-fry the food material in the pot during the process of cooking food material, so that food material can be heated evenly or seasoning added to food material can be more evenly distributed. The stirring assembly 10 includes stirring rod 1 and stirring knife 2, stirring rod 1 can drive stirring knife 2 to move, so as to stir food material, achieve the purpose of stir-frying food material. As shown in Figure 2As shown, the stirring rod 1 is provided with a first mounting hole 11, and the stirring blade 2 is provided with a second mounting hole 21. The stirring assembly 10 further comprises a connecting column 3 and a locking member 4. The connecting column 3 is arranged in the first mounting hole 11 and the second mounting hole 21 to connect the stirring blade 2 and the stirring rod 1. The locking member 4 is used to lock the mounting position of the connecting column 3. The connecting column 3 is connected with the locking member 4, and the locking member 4 is connected with the stirring rod 1 and / or the stirring blade 2. Thus, after the mounting position of the locking member 4 is fixed, the mounting position of the connecting column 3 is locked by the locking member 4, so that the stirring rod 1 and the stirring blade 2 can be reliably connected.

[0032] In some embodiments, in order to reduce the looseness between the stirring blade 2 and the stirring rod 1, the first mounting hole 11, the second mounting hole 21 and the connecting column 3 are usually arranged in a mutually matched shape, so that the connecting column 3 can sufficiently fill the space in the first mounting hole 11 and the second mounting hole 21, thereby forming a relatively tight connection. For example, in an embodiment, the first mounting hole 11 and the second mounting hole 21 can be arranged as circular holes, and the connecting column 3 can be arranged in a cylindrical shape. The connecting column 3 can also be directly used as a standard cylindrical pin, and a damping structure can be arranged between the first mounting hole 11, the second mounting hole 21 and the connecting column 3. The connecting column 3 is arranged between the first mounting hole 11 and the second mounting hole 21. In this design, the stirring blade 2 and the stirring rod 1 are not easy to loosen, and the position of the stirring blade 2 relative to the stirring rod 1 can be adjusted as needed, so that the stirring blade 2 can adapt to different sizes and shapes of pots, etc., to achieve better stirring effect. For another example, in another embodiment, the first mounting hole 11 and the second mounting hole 21 can be arranged as polygonal holes (for example, square holes), and the connecting column 3 can be arranged in a prismatic shape (for example, a quadrangular prism). In this design, the stirring blade 2 and the stirring rod 1 can be completely fixed, and the effect of preventing looseness is better, which is suitable for use scenarios where the position of the stirring blade 2 does not need to be adjusted.

[0033] In some embodiments, the first mounting hole 11 and the second mounting hole 21 are arranged as circular holes, and the connecting column 3 is arranged as a cylindrical shape or directly adopts a cylindrical pin or the like standard part, so that the stirring blade 2 can rotate relative to the stirring rod 1. Meanwhile, the rotating angle range of the stirring blade 2 relative to the stirring rod 1 around the axis direction of the connecting column 3 is arranged as -5° to 5°, that is, the stirring blade 2 can rotate 5° in the clockwise and counterclockwise directions. In the specific design, the angle range of the rotation can be limited by arranging a limiting structure at the limit position of the rotation or the like conventional manner. Through the above design, the stirring blade 2 can automatically adjust the use position by swinging during use, so as to better realize the adhesion with the pot body, the smooth movement, and the effective stirring of the food materials, and the stirring effect is good.

[0034] In the embodiment of the utility model, the principle that the locking piece 4 can lock the installation position of the connecting column 3 is that the stirring rod 1 and the stirring blade 2 belong to the main structure components in the stirring assembly 10, and the locking piece 4 is connected with at least one component in the stirring rod 1 and the stirring blade 2, which is equivalent to that the locking piece 4 is connected to the main part of the stirring assembly 10 and can always keep connected during the use of the stirring assembly 10, so that the locking piece 4 has a firm and stable connection basis. By means of the connection basis, when the connecting column 3 is connected with the locking piece 4, the locking piece 4 can exert a continuous and stable force on the connecting column 3, so that the connecting column 3 is not easy to loosen, thereby realizing reliable locking. Therefore, the design of the locking piece 4 in the utility model has better fixing effect and reliability. It should be noted that the locking piece 4 has various optional embodiments, which are described in detail in the following embodiments.

[0035] The stirring assembly provided in the embodiment of the utility model comprises a stirring rod, a stirring blade, a connecting column and a locking piece. The first mounting hole is arranged on the stirring rod, the second mounting hole is arranged on the stirring blade, and the connecting column is arranged in the first mounting hole and the second mounting hole to connect the stirring blade and the stirring rod. The stirring blade and the stirring rod are connected by the connecting column, and the locking piece is connected with the stirring rod and / or the stirring blade. In this way, the locking piece can lock the position of the connecting column connected in the first mounting hole and the second mounting hole, so that the locking piece and the stirring rod and the stirring blade form a continuous and stable connection. Under the locking action of the locking piece, the connecting column is not easy to loosen and will not automatically separate from the first mounting hole and the second mounting hole, the fixing effect is good, and the reliability of the connection is improved. Meanwhile, the design is also convenient for disassembly, which is conducive to improving the convenience of cleaning and maintenance of the stirring assembly.

[0036] In some embodiments, as shown in FIG. 1, the first mounting hole 11 and the second mounting hole 21 are arranged as circular holes, and the connecting column 3 is arranged as a cylindrical shape or directly adopts a cylindrical pin or the like standard part, so that the stirring blade 2 can rotate relative to the stirring rod 1. Meanwhile, the rotating angle range of the stirring blade 2 relative to the stirring rod 1 around the axis direction of the connecting column 3 is arranged as -5° to 5°, that is, the stirring blade 2 can rotate 5° in the clockwise and counterclockwise directions. In the specific design, the angle range of the rotation can be limited by arranging a limiting structure at the limit position of the rotation or the like conventional manner. Through the above design, the stirring blade 2 can automatically adjust the use position by swinging during use, so as to better realize the adhesion with the pot body, the smooth movement, and the effective stirring of the food materials, and the stirring effect is good. Figure 2As shown, the stirring blade 2 is provided with a bending portion 22, and the bending angle a of the bending portion 22 is set to be between 120° and 150°. Specifically, the bending portion 22 is bent towards the direction in which the stirring blade 2 pushes the food materials for stirring. By such design, not only the structural strength of the stirring blade 2 can be improved and deformation is less likely to occur, but also the bending stirring blade 2 is inclined towards the direction of the food materials, has a better stirring angle, the stirring resistance is reduced, and a better stir-frying effect is achieved.

[0037] As shown in some embodiments, Figure 2 and Figure 3 The locking member 4 includes a connecting body 41 and a lock head 42. The connecting body 41 is an intermediate component for connecting the connecting column 3 and the lock head 42. The connecting body 41 is connected to the connecting column 3, and the shape, size, etc. of the connecting body 41 can be designed as needed. The lock head 42 is used to be fixed on the stirring rod 1 and / or the stirring blade 2. The lock head 42 is connected to the connecting body 41, so as to lock the connecting column 3 through the connecting body 41. Specifically, the lock head 42 has a clamping space 421, and the lock head 42 is provided with an opening 422 communicating with the clamping space 421 for the stirring rod 1 and / or the stirring blade 2 to be clamped in the clamping space 421, so that the lock head 42 can be fixedly installed on the stirring rod 1 and / or the stirring blade 2 through the opening 422.

[0038] It can be understood that the lock head 42 can be fixed on the stirring rod 1 or the stirring blade 2, or can be fixed on both the stirring rod 1 and the stirring blade 2, as long as the lock head 42 can be fixed on at least one of the stirring rod 1 and the stirring blade 2. For the convenience of description, the lock head 42 is fixed on the stirring rod 1 as an example. When the opening 422 is opened, the stirring rod 1 can pass through the opening 422 and be placed in the clamping space 421. When the opening 422 is tightened, the stirring rod 1 cannot be separated from the clamping space 421 through the opening 422, so as to be limited in the clamping space 421. Thus, the lock head 42 is clamped and fixed on the stirring rod 1, and the lock head 42 cannot be easily separated from the stirring rod 1, so as to limit the installation position of the connecting column 3.

[0039] To adjust the size of the opening 422, optionally, in some embodiments, the lock head 42 can be designed in reference to the existing clamps, i.e. the opening 422 is tightened by connecting the fasteners and opened by disassembling the fasteners. In some embodiments, the lock head 42 can also be designed as an elastic piece structure, when it is needed to open the opening 422, an external force can be applied to the lock head 42 to make the opening 422 open, and when there is no external force, the opening 422 remains tightened. In this way, the size of the opening 422 can be adjusted as needed by the elasticity of the lock head 42 itself, without the need for additional fasteners, which can save the use of parts, and the operation process does not need to use tools, and the operation is more convenient and easy to disassemble. At the same time, the lock head 42 has good durability when used correctly, and is not easy to loosen after repeated assembly and disassembly, so that it does not need to be replaced frequently, which is conducive to long-term use.

[0040] The above embodiments design the structure of the lock head 42, so that the stirring rod 1 and / or the stirring knife 2 are clamped into the clamping space 421 through the opening 422 which can be opened or tightened, thereby realizing reliable fixation of the lock head 42. The lock head 42 is connected with the connecting column 3 through the connecting body 41, thereby realizing the locking effect on the connecting column 3, which is clever in design, easy to operate, and has good reliability.

[0041] It can be understood that the specific orientation of the opening 422 can be designed flexibly, as long as it can be clamped into the clamping space 421. For example, in some embodiments, the orientation of the opening 422 is the same as the direction in which the connecting column 3 is arranged in the first mounting hole 11 and the second mounting hole 21. In this way, when the connecting column 3 is arranged in the first mounting hole 11 and the second mounting hole 21, the stirring rod 1 and / or the stirring knife 2 can be clamped into the clamping space 421 through the opening 422, thereby completing the installation in one step and being easy to operate. For example, as shown in Figure 2 the orientation of the opening 422 is perpendicular to the direction in which the connecting column 3 is arranged in the first mounting hole 11 and the second mounting hole 21. In this way, the connecting column 3 is arranged in the first mounting hole 11 and the second mounting hole 21 first, and then the stirring rod 1 and / or the stirring knife 2 are clamped into the clamping space 421 through the opening 422, which can also realize reliable locking. In addition, the orientation of the opening 422 can also be adjusted, for example, in some embodiments, the connecting column 3 is fixedly connected to one end of the connecting body 41, and the lock head 42 is movably connected to the other end of the connecting body 41. When the lock head 42 moves relative to the connecting body 41, the orientation of the opening 422 can be adjusted as needed, which is more flexible.

[0042] In some embodiments, as shown in Figure 2As shown, when the orientation of the opening 422 is perpendicular to the penetrating direction of the connecting column 3 penetrating into the first mounting hole 11 and the second mounting hole 21, one end of the connecting column 3 is movably connected to the connecting body 41, and the other end of the connecting body 41 is fixedly connected to the lock head 42. In this way, the connecting body 41 can move relative to the connecting column 3, and further drive the lock head 42 to move, so that the lock head 42 can be mounted or dismounted as needed. Specifically, since the connecting column 3 penetrates into the first mounting hole 11 and the second mounting hole 21 along the axial direction of the connecting column 3, the direction in which the connecting column 3 is separated from the first mounting hole 11 and the second mounting hole 21 is also the axial movement in the opposite direction of the mounting direction. The structure design that the orientation of the opening 422 is perpendicular to the penetrating direction of the connecting column 3 penetrating into the first mounting hole 11 and the second mounting hole 21 can make the movement of the connecting column 3 separating from the first mounting hole 11 and the second mounting hole 21 and the movement of the lock head 42 separating from the first mounting hole 11 and the second mounting hole 21 not in the same direction, and just be limited by the lock head 42 in the perpendicular direction, so that the connecting column 3 cannot be separated, and the stability of the mounting position of the connecting column 3 is better ensured.

[0043] Of course, it can be understood that the movable connection between the connecting column 3 and the connecting body 41 in the above embodiment can also be replaced by fixed connection. When the connecting column 3 and the connecting body 41 are fixedly connected, the connecting body 41 can be set as a component with elasticity, and the elastic deformation of the connecting body 41 is used to drive the lock head 42 to move, and in this way, the mounting or dismounting of the lock head 42 can also be achieved. In addition, the first mounting hole 11 and the second mounting hole 21 can be set as circular holes, and the connecting column 3 can be set as a cylindrical shape, so that the connecting body 41 and the lock head 42 can be driven to move by rotating the connecting column 3 in the mounting hole, so as to achieve the mounting or dismounting of the lock head 42.

[0044] In some embodiments, as shown in Figure 3 The connecting body 41 is provided with a reinforcing rib 411. The reinforcing rib 411 can be directly formed by stamping a protruding part on the connecting body 41. The reinforcing rib 411 can be designed according to the strength requirement of the connecting body 41. Generally, when the connecting body 41 adopts a plate-shaped structure as shown in Figure 3 The reinforcing rib 411 can be added to increase the strength of the connecting body 41, so that the connecting body 41 is not easy to bend or break under external force impact, and the reliability is better. Of course, it can be understood that when the strength of the connecting body 41 itself meets the use requirement, the reinforcing rib 411 can also not be provided on the connecting body 41 to save cost.

[0045] In another embodiment, as shown in Figure 4As shown, the connecting column 3 can be provided with a thread, and the locking member 4 can be provided with a connecting nut 43 and a lock nut 44. The connecting nut 43 is threadedly connected with the connecting column 3 and abuts against the stirring rod 1 and / or the stirring blade 2. The lock nut 44 is also threadedly connected with the connecting column 3, and the lock nut 44 is further provided with a lock structure which is connected with the connecting nut 43. Alternatively, the lock structure can have various embodiments, for example, in one embodiment, the lock structure is a boss structure which is offset from the geometric axis of the lock nut 44, and the boss structure is inserted into a corresponding recess structure provided on the connecting nut 43, so that the friction between the boss structure and the recess structure can prevent the connecting nut 43 from loosening. For another example, in one embodiment, the lock structure is a friction structure which abuts against the connecting nut 43, and the friction on the abutting surface can prevent the connecting nut 43 from loosening. Meanwhile, the internal thread of the lock nut 44 can be provided with a rotation direction which is opposite to that of the connecting nut 43, so that when the connecting nut 43 rotates in the loosening direction, the lock nut 44 will be driven to rotate in the tightening direction, thereby forming a self-locking. In the above embodiments, the connecting nut 43 is connected with the thread on the connecting column 3, and the lock nut 44 is provided to effectively prevent the connecting nut 43 from loosening, so that the connecting nut 43 can maintain the abutting and extruding effect with the stirring rod 1 and / or the stirring blade 2, thereby achieving reliable connection and fixation.

[0046] In yet another embodiment, as shown in Figure 5 the locking member 4 can be provided as a nut, and the connecting column 3 can be provided with a first thread 31 and a second thread 32 along the axis in sequence, and the pitch of the first thread 31 is not equal to the pitch of the second thread 32. For example, in one specific embodiment, the locking member 4 can be provided as a standard nut, the first thread 31 can be provided as a standard thread, and the pitch of the second thread 32 can be slightly smaller than that of the first thread 31. In this way, when the locking member 4 rotates around the connecting column 3 and passes through the first thread 31, the locking member 4 can be clamped between the first thread 31 and the second thread 32 with smaller pitch, thereby achieving the effect of self-locking and anti-loosening. In the above embodiments, the locking member 4 can directly abut against the stirring rod 1 and / or the stirring blade 2, or indirectly abut against the stirring rod 1 and / or the stirring blade 2 through a gasket or the like, and in combination with the self-locking and anti-loosening effect of the connection between the locking member 4 and the second thread 32, the reliable connection and fixation can be achieved.

[0047] In some embodiments, the locking member 4 can also be provided as a buckle, and the stirring rod 1 and / or the stirring blade 2 can be provided with a clamping hole in correspondence, and the locking can be achieved by clamping the buckle and the clamping hole. In this way, the installation position of the connecting column 3 can be reliably locked, and the installation and dismounting of the locking member 4 can be more convenient.

[0048] As shown in Figure 6As shown, the utility model still provides a kind of cooking machine 100, including body 20 and above-mentioned stirring assembly 10, and stirring rod 1 is connected on body 20.The cooking machine 100 provided by the utility model, since the stirring assembly 10 described above is used, stirring knife 2 is connected firm between stirring rod 1, and it is not easy to loosen, therefore, cooking machine 100 has better reliability when using, can realize the stable stirring of food material, better guarantee the stability of stirring effect.And, stirring assembly 10 is also convenient to disassemble, to improve the convenience of cleaning and maintenance to the structure of stirring assembly 10 itself.

[0049] The above merely describes preferred embodiments of the utility model and is not intended to limit the utility model, and any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
