[0051] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application will be described clearly and completely below with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the described embodiments of the present application, all other embodiments obtained by a person of ordinary skill in the art without any inventive effort fall within the scope of protection of the present application.

[0053] In order to keep the following description of the embodiments of the present application clear and concise, detailed descriptions of known functions and known components are omitted in the present application.

[0054] The embodiments of the present application provide a cutter device for a cooking machine, in particular for a pot body 5 of the cooking machine, for stirring and cutting food materials in the pot body 5.

[0055] As shown in Figures 1 to 5 The cutter device of the embodiments of the present application includes a cutter seat 1, a rotating cutter 3 and a fixed cutter 2. The cutter seat 1 includes a seat body 11 and a rotating shaft 12. The seat body 11 is fixed to the bottom of the pot body 5 of the cooking machine. The rotating shaft 12 is arranged through the seat body 11 and is arranged substantially vertically. The lower end of the rotating shaft 12 extends out of the pot body 5 and is connected to a driving mechanism of the cooking machine. The driving mechanism is used to drive the rotating shaft 12 to rotate around its own axis. The fixed cutter 2 is fixed to the seat body 11 and has at least a first gap 24. The rotating cutter 3 is arranged at the upper end of the rotating shaft 12 and includes at least a first moving cutter blade 31. The rotating cutter 3 can rotate with the rotating shaft 12, so that the first moving cutter blade 31 passes through the first gap 24 and cooperates with the fixed cutter 2 to cut the food materials.

[0056] The cutting tool device of the embodiment of the present application utilizes the clearance between the fixed knife 2 and the rotating knife 3 to simultaneously apply pressure and cut the food. The rotating knife 3 rotates at a low speed to form the food into uniform granules, thereby achieving a good chopping effect.

[0057] In some embodiments, as Figure 3 As shown, the fixed blade 2 also has a second gap 25, and the second gap 25 is located above the first gap 24. Figure 4 As shown, the rotating blade 3 also includes a second movable blade 32. The first movable blade 31 and the second movable blade 32 are offset in the axial direction of the rotating shaft 12. In this embodiment, the second movable blade 32 is taller than the first movable blade 31. As the rotating blade 3 rotates, the second movable blade 32 passes through the second gap 25 and cooperates with the stationary blade 2 to cut the food. By providing the second gap 25 in the stationary blade 2 and simultaneously providing the second movable blade 32 on the rotating blade 3, which can pass through the second gap 25, the second movable blade 32 cooperates with the stationary blade 2 to cut the food, improving cutting efficiency.

[0058] In some embodiments, continued binding Figure 3 The fixed blade 2 includes a first fixed blade 21, a second fixed blade 22, and a third fixed blade 23, arranged sequentially from bottom to top. A first gap 24 is formed between the first and second fixed blades 21, 22, and a second gap 25 is formed between the second and third fixed blades 22, 23. As the rotating blade 3 rotates, the first movable blade 31 cooperates with the first and second fixed blades 21, 22 to chop the food, while the second movable blade 32 cooperates with the second and third fixed blades 22, 23 to chop the food. The use of three spaced fixed blades to form the first and second gaps 24, 25, respectively, not only simplifies the structure but also improves the cutting effect through the coordination between the fixed and movable blades.

[0059] It is understandable that the size of the first gap 24 should be larger than the thickness of the first movable blade 31, and the size of the second gap 25 should be larger than the thickness of the second movable blade 32, so that the movable blades can pass smoothly through the corresponding gaps without interfering with the fixed blades.

[0060] When the first movable blade 31 passes through the first gap 24 and the second movable blade 32 passes through the second gap 25, they must not interfere with the fixed blades and must maintain an appropriate distance to cut the food into the appropriate size. A larger distance results in a larger particle size, while a smaller distance results in a smaller particle size.

[0061] In some embodiments, the distance between the first movable blade 31 and the first fixed blade 21 and the second fixed blade 22 when passing through the first gap 24 can be set to 0.5 mm to 5 mm, respectively. When the second movable blade 32 passes through the second gap 25, the distance between it and the second fixed blade 22 and the third fixed blade 23 can be set to 0.5 mm to 5 mm, respectively. These dimensions are designed appropriately, not only allowing the two movable blades to pass smoothly through the two gaps without interfering with the fixed blades, but also utilizing the distance between the movable and fixed blades to cut food into appropriate sizes.

[0062] It is understandable that the above distance can be adjusted appropriately according to the required particle size of the food after cutting. For example, the minimum distance can be less than 0.5mm, such as 0.1, 0.05, etc., and the maximum distance can be greater than 5mm, such as 6mm, 8mm, etc.

[0063] In some embodiments, continued binding Figure 3 The fixed knife 2 also includes a fixed knife holder 26, which has a limiting hole 261. The fixed knife holder 26 is sleeved on the base 11 through the limiting hole 261. The base 11 is used to limit the rotation of the fixed knife holder 26. Figure 4 As shown, the rotating blade 3 also includes a movable blade holder 33, which is fixed to the upper end of the rotating shaft 12 and located above the fixed blade holder 26. The movable blade holder 33 is used to axially limit the fixed blade holder 26, preventing the fixed blade 2 from moving up and down, thereby avoiding interference and collision with the rotating blade 3 during rotation. The fixed blade 2 is fixed to the bottom of the pot body 5 through the cooperation of its own limiting hole 261 with the base 11 and the axial limitation of the movable blade holder 33. The fixing method is simple and reasonable.

[0064] like Figure 1 and Figure 4 As shown, the first movable blade 31 and the second movable blade 32 are respectively arranged on opposite sides of the movable blade holder 33, so that when the rotating knife 3 is rotating, the first movable blade 31 and the second movable blade 32 can pass through different gaps of the fixed knife 2 in sequence, so that one movable blade is in a cutting state and the other movable blade is in a stirring state, thereby achieving uniform distribution and cutting of ingredients during the stirring process, making it easier to fully mix and crush the ingredients and avoiding dead corners in cutting; and the symmetrically arranged movable blades can also effectively distribute mechanical power and reduce friction caused by unbalanced force, which not only improves the power output of the cooking machine, but also reduces mechanical wear and extends the service life of the machine.

[0065] For example, the first moving blade 31 is first extended obliquely downward by the moving blade holder 33, and then extended laterally outward to form the first moving blade 31, and the laterally extended part forms the effective cutting part of the first moving blade 31 and passes through the first gap 24 when the rotating knife 3 rotates. The second moving blade 32 is directly extended laterally outward by the moving blade holder 33, so that the height of the second moving blade 32 is higher than the laterally extended part of the first moving blade 31.

[0066] In some embodiments, as shown in Figure 3 The first fixed blade 21 is formed by extending outward from the circumferential side of the fixed blade holder 26, and the bottom surface of the first fixed blade 21 and the bottom surface of the fixed blade holder 26 are both flat and form a support surface 28 together, which abuts against the inner bottom surface of the pot body 5 (see Figure 1 ), so that the stability of the first fixed blade 21 can be ensured.

[0067] Continuing to combine Figure 3 The end of the first fixed blade 21 away from the fixed blade holder 26 extends upward to form a connecting part 27, and the outer side surface of the connecting part 27 abuts against the inner side wall of the pot body 5 near the bottom (see Figure 1 ), which can further enhance the stability of the first fixed blade 21. One end of the second fixed blade 22 and one end of the third fixed blade 23 are connected to the inner side surface of the connecting part 27, and the other end of the second fixed blade 22 and the other end of the third fixed blade 23 are both free ends and face the rotating shaft 12. The arrangement of the three fixed blades is ingenious and reasonable, which is conducive to forming multiple gaps arranged in sequence from top to bottom, and can also ensure the stability of the entire fixed knife 2 arranged in the pot body 5.

[0068] It can be understood that the number of gaps of the fixed knife 2 of the embodiments of the present application is not limited to one or two, but can be more than two. When the number of gaps is more than two, the rotating knife 3 is provided with more moving blades corresponding thereto, and the multiple moving blades are arranged in a staggered manner in the axial direction of the rotating shaft 12 to avoid interference. In addition, multiple fixed blades arranged in sequence from bottom to top can be arranged on different sides (circumferential direction) of the fixed blade holder 26 of the fixed knife 2, and multiple gaps arranged in sequence from bottom to top are formed respectively; when the rotating knife 3 rotates, the same moving blade will pass through multiple gaps at the same height to cut multiple times.

[0069] In some embodiments, as shown in Figure 4 The rotating knife 3 further includes a shaft rod 34, the lower end of the shaft rod 34 is connected to the moving blade holder 33, the upper end of the shaft rod 34 is provided with a limiting part 341, and the outer circumferential side surface of the limiting part 341 is a circular arc surface. The inner side of the pot cover 9 of the cooking food processor is provided with a limiting groove 91 with a notch downward, see Figure 7 and Figure 8The circumferential side of the limiting groove 91 is a circular arc surface. The radial dimension of the limiting groove 91 is greater than the radial dimension of the limiting portion 341, so that when the pot cover 9 is placed on the pot body 5, the limiting portion 341 extends into the limiting groove 91, and the top of the limiting portion 341 is in clearance fit with the groove bottom of the limiting groove 91, so that the limiting portion 341 can rotate in the limiting groove 91. The rotating knife 3 is provided with the shaft rod 34 with the limiting portion 341, and the limiting portion 341 is in fit with the limiting groove 91 on the inner side of the pot cover 9, so that the rotating knife 3 can be limited in axial and radial directions, and the rotating knife 3 is prevented from moving up and down and left and right, and interference and collision between the rotating knife 3 and the fixed knife 2 are avoided, and the rotation of the rotating knife 3 is not affected.

[0070] For example, the top of the limiting portion 341 can be designed as a flat surface, and the groove bottom of the limiting groove 91 corresponding to the slot is also a flat surface. When the limiting portion 341 extends into the limiting groove 91, the top flat surface of the limiting portion 341 is close to the groove bottom flat surface of the limiting groove 91, but the two do not contact each other and leave a small gap, so as to avoid friction between the limiting portion 341 and the limiting groove 91 when the rotating knife 3 rotates. The small gap allows the rotating knife 3 to move slightly in the axial direction, and the movement will not cause the rotating knife 3 to contact the fixed blade when passing through the gap of the fixed blade.

[0071] Optionally, the upper end of the rotating shaft 12 of the knife seat 1 can be provided with a clamping flat or other key-shaped clamping portion. The movable knife holder 33 of the rotating knife 3 is provided with an assembly hole, and the rotating knife 3 is assembled on the rotating shaft 12 of the knife seat 1 through the assembly hole and is clamped to rotate with the rotating shaft 12 when the rotating shaft 12 rotates. The outer circumferential surface of the seat body 11 is polygonal or key-shaped or other clamping structure, and the limiting hole 261 on the fixed knife holder 26 of the fixed knife 2 is adapted to the shape of the seat body 11. When the seat body 11 is arranged in the limiting hole 261, the rotation of the fixed knife holder 26 (the fixed knife 2) is limited. The cooperation between the rotating knife 3 and the rotating shaft 12 and the cooperation between the fixed knife 2 and the seat body 11 enable the rotating knife 3 and the fixed knife 2 to be disassembled from the knife seat 1, so as to facilitate cleaning of the rotating knife 3 and the fixed knife 2.

[0072] Since the cutter device of the embodiment of the present application is used for cutting food by the gap fit between the movable blade and the fixed blade, the movable blade and the fixed blade can not be provided with sharp blade portions, but are thick plates, so as to avoid the risk of cutting hands caused by accidental contact during disassembly and cleaning.

[0073] In some embodiments, as shown in Figure 1 , the bottom of the pot body 5 is provided with a buckling member 6, and the buckling member 6 is provided with a stop table 61 (see Figure 9 and Figure 10 ). As shown in Figure 5As shown, the knife seat 1 further comprises a positioning sleeve 13 sleeved on the rotating shaft 12 and capable of rotating relative to the rotating shaft 12, for example, bearings 14 are arranged between the positioning sleeve 13 and the rotating shaft 12. The upper portion of the positioning sleeve 13 is fixedly connected with the bottom of the seat body 11, and the lower portion of the positioning sleeve 13 is provided with a boss 131 on the outer circumferential side, the lower portion of the positioning sleeve 13 is inserted into the buckling member 6, and the boss 131 is screwed into the lower portion of the stop platform 61 to achieve clamping. The knife seat 1 can be fixed on the bottom of the pot body 5 through the buckling member 6, and the fixing mode is simple and reliable.

[0074] As shown in the drawings, Figure 9 As shown, the middle portion of the buckling member 6 is provided with a through cavity 62, and the stop platform 61 is arranged on the wall of the cavity 62. In this embodiment, three stop platforms 61 are arranged at intervals (distributed at an angle of 120° around the wall of the cavity 62). Figure 5 As shown, the positioning sleeve 13 of the knife seat 1 is provided with three bosses 131 (distributed at an angle of 120° around the outer periphery of the positioning sleeve 13). When the positioning sleeve 13 of the knife seat 1 is inserted into the cavity 62 and the knife seat 1 is rotated, the three bosses 131 are correspondingly screwed into the lower portion of the three stop platforms 61 (see Figure 10 ), limiting the upward movement of the knife seat 1, and the seat body 11 of the knife seat 1 is stopped above the stop platform 61, so that the knife seat 1 is fixed to the pot body 5.

[0075] As shown in the drawings, Figure 1 As shown, the upper portion of the positioning sleeve 13 penetrates through the bottom of the pot body 5 and extends into the pot body 5, the seat body 11 of the knife seat 1 is located in the pot body 5, the upper portion of the positioning sleeve 13 is sleeved with a sealing ring 15, and the bottom of the seat body 11 abuts against the sealing ring 15, so that the sealing ring 15 is pressed against the inner side of the bottom of the pot body 5, to avoid the liquid in the pot body 5 from leaking out of the pot body 5 through the gap between the pot body 5 and the positioning sleeve 13.

[0076] The cooking food processor of the embodiment of the present application is designed with two knife tools, i.e., a rotating knife 3 and a fixed knife 2, both of which can be disassembled and cleaned to improve the hygiene and safety. Through the cooperation of the rotating knife 3 and the pot cover 9, and the axial positioning of the rotating knife 3 on the fixed knife 2, the collision damage caused by the axial displacement of the rotating knife 3 and the fixed knife 2 is avoided.

[0077] The embodiment of the present application also provides a cooking food processor, as shown in the drawings, Figures 6 to 11 The cooking food processor comprises a main machine 4, a pot body 5 and the knife tool device in any one of the above embodiments. The main machine 4 is provided with a driving mechanism, and the bottom of the main machine 4 is provided with an openable bottom cover 43. The pot body 5 is detachably arranged on the top of the main machine 4, the knife seat 1 of the knife tool device is fixed to the bottom of the pot body 5, the rotating knife 3 and the fixed knife 2 of the knife tool device are located in the pot body 5 and arranged on the knife seat 1, and the rotating knife 3 is connected with the driving mechanism and rotates under the driving of the driving mechanism.

[0078] The cooking food processor can cut and crush food materials at low speed of the rotating cutter 3, reduce noise and vibration, and prevent food from splashing on the pot cover 9, thereby reducing cleaning difficulty.

[0079] In some embodiments, as shown in Figure 7 and Figure 11 The driving mechanism includes a motor 7 and a speed reducer 8 connected with the motor 7, and the speed reducer 8 is provided with an output connecting head 81.
