[0002] With the increasing improvement of people's living standards, many different types of food processors have emerged on the market, such as cooking machines, juicers, and wall breakers. To facilitate the cleaning of the mixing cup of the food processor, the mixing knife disc assembly is detachably assembled at the bottom of the mixing cup. During cleaning, the entire mixing knife disc assembly needs to be disassembled for cleaning, resulting in a rather complex disassembly and assembly process. Moreover, when the mixing knife disc assembly is being cleaned, water vapor is likely to invade the mixing knife disc assembly and come into contact with electronic components, thereby causing malfunction of the electronic components.

[0003] To solve the above problems, some manufacturers detachably assemble the mixing knife group on the driving rotating shaft so that the mixing knife group and the driving rotating shaft can be separated from each other, and a specific edge structure is provided on the driving rotating shaft to drive the mixing knife group. This also causes that when assembling, users need to accurately align the edges and corners of the driving rotating shaft and the mixing knife group for installation, and there is no positioning reference when the mixing knife group rotates, which easily leads to jitter or falling off, seriously affecting the user experience.

[0030] Embodiment 1:

[0031] Refer to Figure 1 、 Figure 2 and Figure 3, this application discloses a detachable stirring knife assembly, which is applied to food processors such as cooking machines, juicers and blenders. In this embodiment, the detachable stirring knife assembly includes a stirring knife group 1, a driving rotating shaft 2, a first buckle portion 3 and a second buckle portion 4. Preferably, the stirring knife group 1 includes a stirring blade 11 and a stirring knife seat 12. The stirring blade 11 is assembled on the outer side of the stirring knife seat 12, and the stirring knife seat 12 is provided with a driving hole 13; the driving rotating shaft 2 is detachably inserted through the driving hole 13; the first buckle portion 3 is arranged on the driving rotating shaft 2 and can rotate along with the driving rotating shaft 2; the second buckle portion 4 is arranged in the driving hole 13. When the driving rotating shaft 2 rotates relative to the stirring knife seat 12, the first buckle portion 3 is connected with the second buckle portion 4 in cooperation to lock the stirring knife group 1 to the driving rotating shaft 2. In this way, by inserting the driving rotating shaft 2 into the driving hole 13, the driving rotating shaft 2 drives the first buckle portion 3 to rotate relative to the stirring knife seat 12, so that the first buckle portion 3 is connected with the second buckle portion 4 in cooperation, thereby automatically locking the stirring knife group 1 to the driving rotating shaft 2. Furthermore, the cooperatively connected first buckle portion 3 and second buckle portion 4 are used as a positioning reference, so that the stirring knife group 1 and the driving rotating shaft 2 are relatively stationary and rotate synchronously, optimizing the installation steps of the stirring knife group 1, preventing the stirring knife group 1 from shaking or falling off during use, and improving the user experience.

[0032] Optionally, the first buckle portion 3 can be an independent component or a partial structure on the driving rotating shaft 2; optionally, the second buckle portion 4 can be an independent component or a partial structure in the driving hole 13; preferably, when the driving rotating shaft 2 is inserted through the driving hole 13, the driving rotating shaft 2 and the stirring knife seat 12 can still rotate relative to each other. When the driving rotating shaft 2 rotates relative to the stirring knife seat 12, the first buckle portion 3 rotates along with the driving rotating shaft 2 relative to the stirring knife seat 12, so as to drive the first buckle portion 3 to be connected with the second buckle portion 4 in cooperation, realizing automatic locking of the stirring knife to the driving rotating shaft 2. Furthermore, the cooperatively connected first buckle portion 3 and second buckle portion 4 are used as a positioning reference, so that the stirring knife group 1 and the driving rotating shaft 2 are relatively stationary and rotate synchronously.

[0033] Refer to Figure 2 , Figure 3 and Figure 4, in this embodiment, the driving rotating shaft 2 includes a driving section 21 and a transmission section 22. The driving section 21 is equipped with a cutter head 5. The lower end of the transmission section 22 is connected to the upper end of the driving section 21. The stirring cutter seat 12 is sleeved outside the transmission section 22 through the driving hole 13, and the first clamping portion 3 is arranged on the transmission section 22. Optionally, the cutter head 5 is used to fix the driving rotating shaft 2 in the cooking cup of the food processor. The driving section 21 penetrates through the cutter head 5 and extends out of the cooking cup for connection with the stirring motor of the food processor, so that the stirring motor drives the driving rotating shaft 2 to rotate. Optionally, the stirring cutter seat 12 is movably sleeved outside the transmission section 22 through the driving hole 13, so that relative rotation can occur between the driving rotating shaft 2 and the stirring cutter seat 12. Specifically, when the stirring motor drives the driving rotating shaft 2 to rotate, the driving rotating shaft 2 drives the first clamping portion 3 to rotate relative to the stirring cutter seat 12, driving the first clamping portion 3 to cooperate and connect with the second clamping portion 4, realizing automatic locking of the stirring cutter to the driving rotating shaft 2. Furthermore, the cooperatively connected first clamping portion 3 and second clamping portion 4 are used as a positioning reference, so that the stirring cutter group 1 and the driving rotating shaft 2 are relatively stationary and rotate synchronously.

[0034] Refer to Figure 2 , Figure 3 and Figure 4 , in this embodiment, the diameter of the driving section 21 is greater than or equal to the diameter of the transmission section 22. In this way, the driving section 21 with a larger diameter is located below the transmission section 22 with a smaller diameter, so that the driving section 21 can limit the stirring cutter group 1, prevent the stirring cutter group 1 from moving downward under the action of gravity, and avoid the stirring cutter seat 12 falling off the transmission section 22.

[0035] Refer to Figure 2 , Figure 3 and Figure 4 , in this embodiment, an elastic limiting ring 6 is further included. The elastic limiting ring 6 is arranged between the upper end of the driving section 21 and the lower end of the stirring cutter seat 12. Optionally, an assembly groove is arranged at the lower end of the transmission section 22, and the elastic limiting ring 6 is nested in the assembly groove, so that the elastic limiting ring 6 is fixed between the upper end of the driving section 21 and the lower end of the stirring cutter seat 12, can drive the stirring cutter seat 12 to be tightly connected with the driving rotating shaft 2, further optimize the connection stability between the stirring cutter seat 12 and the driving rotating shaft 2, and prevent the stirring cutter group 1 from shaking or falling off during use.

[0036] Refer to Figure 2 , Figure 3 and Figure 4, in this embodiment, the first buckle portion 3 includes a limiting section 23, a limiting block 31 and a limiting groove 32. The limiting section 23 is connected to the upper end of the transmission section 22. The limiting block 31 is arranged on the outer side of the limiting section 23. The limiting groove 32 is arranged between the limiting block 31 and the transmission section 22. The limiting groove 32 is used for cooperating and connecting with the second buckle portion 4. Optionally, the limiting block 31 can be integrally formed with the limiting section 23. Optionally, the limiting block 31 can be replaced by a pin column or other structures assembled on the limiting section 23. Preferably, the limiting section 23, the transmission section 22 and the driving section 21 are integrally formed, so that the whole driving rotating shaft 2 has better strength and can effectively drive the stirring knife group 1 to rotate in various application scenarios to realize grinding and chopping of different food materials. Optionally, referring to Figure 4 As shown, the limiting blocks 31 are arranged on both opposite sides of the limiting section 23, so that two limiting grooves 32 are respectively formed at intervals between the two limiting blocks 31 and the upper end of the transmission section 22. Correspondingly, two second buckle portions 4 are arranged in the driving hole 13. In this way, through the cooperation and connection of the two limiting grooves 32 with the corresponding second buckle portions 4 respectively, the driving rotating shaft 2 can form a stable connection with the stirring knife seat 12. Optionally, the maximum distance between the two limiting blocks 31 is L1, the diameter of the transmission section 22 is L2, the outer diameter of the elastic limiting ring 6 is L3, the diameter of the driving section 21 is L4, and the diameter of the limiting section 23 is L5. Optionally, 85%L4 ≤ L2 ≤ L4, 6mm ≤ L2 ≤ 8mm, 7mm ≤ L3 ≤ 10mm, 4mm ≤ L5 ≤ L1 ≤ L2 ≤ 8mm. Preferably, L5 < L1, L5 < L2, L1 ≤ L2. In this way, the limiting groove 32 formed at intervals between the lower end of the limiting block 31 and the upper end of the transmission section 22, that is, when the stirring motor drives the driving rotating shaft 2 to rotate, the driving rotating shaft 2 drives the first buckle portion 3 to rotate relative to the stirring knife seat 12, and drives the limiting groove 32 to cooperate and connect with the second buckle portion 4, that is, the second buckle portion 4 is limited between the lower end of the limiting block 31 and the upper end of the transmission section 22, so as to automatically lock the stirring knife to the driving rotating shaft 2. Thus, the first buckle portion 3 and the second buckle portion 4 which are cooperatively connected are used as a positioning reference, so that the stirring knife group 1 and the driving rotating shaft 2 are relatively stationary and rotate synchronously.

[0037] Referring to Figure 2 , Figure 5 and Figure 6, in this embodiment, the second buckle portion 4 includes at least one limiting projection 41 disposed in the driving hole 13, and the projections of the first buckle portion 3 and the limiting projection 41 on the horizontal plane are arranged along the rotation direction. Optionally, the limiting projection 41 and the stirring knife seat 12 are integrally formed; optionally, the limiting projection 41 protrudes from the inner wall of the driving hole 13 towards the center. Specifically, when the stirring motor drives the driving rotating shaft 2 to rotate, the driving rotating shaft 2 drives the first buckle portion 3 to rotate relative to the stirring knife seat 12, causing the limiting groove 32 to cooperate with the limiting projection 41, that is, the limiting projection 41 is limited between the lower end of the limiting block 31 and the upper end of the transmission section 22, so as to automatically lock the stirring knife to the driving rotating shaft 2. Furthermore, the cooperatively connected first buckle portion 3 and second buckle portion 4 are used as a positioning reference, so that the stirring knife group 1 and the driving rotating shaft 2 are relatively stationary and rotate synchronously.

[0038] Refer to Figure 5 and Figure 6 , in this embodiment, the second buckle portion 4 further includes a limiting block 42 disposed at one end of the limiting projection 41 away from the first buckle portion 3 for abutting against the first buckle portion 3 to limit the rotation amplitude of the driving rotating shaft 2 relative to the stirring knife seat 12. In this way, when the driving rotating shaft 2 drives the first buckle portion 3 to rotate relative to the stirring knife seat 12, the limiting projection 41 cooperates with the limiting groove 32, and the limiting block 31 of the first buckle portion 3 abuts against the limiting block 42 to limit the rotation amplitude of the driving rotating shaft 2 relative to the stirring knife seat 12, so that the limiting block 31 of the first buckle portion 3 pushes the stirring knife seat 12 to rotate through the limiting block 42, thereby automatically locking the stirring knife group 1 to the driving rotating shaft 2. Furthermore, the cooperatively connected first buckle portion 3 and second buckle portion 4 are used as a positioning reference to drive the stirring knife group 1 and the driving rotating shaft 2 to be relatively stationary and rotate synchronously.

[0039] Refer to Figure 5 and Figure 6, in this embodiment, the second buckle portion 4 further includes a guiding inclined surface 43, which is disposed at one end of the limiting protrusion 41 close to the first buckle portion 3 and is used to guide the cooperation connection between the first buckle portion 3 and the second buckle portion 4. Preferably, the guiding inclined surface 43 is inclined downward along the rotation direction, so that when the driving rotating shaft 2 drives the first buckle portion 3 to rotate relative to the mixing knife seat 12, the limiting block 31 abuts against the guiding inclined surface 43. Under the guiding action of the guiding inclined surface 43, the limiting protrusion 41 is in cooperation connection with the limiting groove 32. At the same time, the limiting block 31 can drive the mixing knife seat 12 to move downward to compress the elastic limiting ring 6, so that the elastic limiting ring 6 is in interference fit between the lower end of the mixing knife seat 12 and the upper end of the driving section 21, driving the mixing knife seat 12 to be stably connected to the driving rotating shaft 2 to avoid situations such as detachment. And by the limiting block 31 abutting against the limiting stop block 42, the rotation amplitude of the driving rotating shaft 2 relative to the mixing knife seat 12 is limited, so that the limiting block 31 drives the mixing knife seat 12 to rotate by pushing the limiting stop block 42, thereby realizing automatically locking the mixing knife group 1 to the driving rotating shaft 2. Furthermore, by using the cooperatively connected first buckle portion 3 and second buckle portion 4 as a positioning reference, the mixing knife group 1 and the driving rotating shaft 2 are relatively stationary and rotate synchronously.

[0040] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6, in this embodiment, when assembling the stirring knife group 1, only need to sleeved the stirring knife seat 12 on the outside of the transmission section 22 through the driving hole 13, so that the lower end of the stirring knife seat 12 abuts against the elastic limiting ring 6. When the stirring motor drives the driving rotating shaft 2 to rotate, the driving rotating shaft 2 drives the first buckle part 3 to rotate relative to the stirring knife seat 12, so that the limiting block 31 abuts against the guiding inclined surface 43. Under the guiding action of the guiding inclined surface 43, the limiting convex block 41 is connected with the limiting groove 32 in a matching way. At the same time, the limiting block 31 can drive the stirring knife seat 12 to move downward to press the elastic limiting ring 6, so that the elastic limiting ring 6 is in interference fit between the lower end of the stirring knife seat 12 and the upper end of the driving section 21, driving the stirring knife seat 12 to be stably connected to the driving rotating shaft 2, avoiding situations such as coming off. And by the limiting block 31 abutting against the limiting stop block 42, the rotation amplitude of the driving rotating shaft 2 relative to the stirring knife seat 12 is limited, so that the limiting block 31 pushes the stirring knife seat 12 to rotate through the limiting stop block 42, thereby automatically locking the stirring knife group 1 to the driving rotating shaft 2. Furthermore, by using the first buckle part 3 and the second buckle part 4 which are connected in a matching way as the positioning reference, the stirring knife group 1 and the driving rotating shaft 2 are driven to be relatively static and rotate synchronously, realizing the optimization of the installation steps of the stirring knife group 1, preventing the stirring knife group 1 from shaking or falling off during use, and improving the user experience.

[0041] Embodiment Two:

[0042] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7, the main difference between this embodiment and the first embodiment is that: the second buckle portion 4 includes at least two limiting bumps 41; the two limiting bumps 41 are arranged at intervals along the rotation direction in the driving hole 13, and any one of the two limiting bumps 41, the first buckle portion 3 and the other of the two limiting bumps 41 are arranged in sequence along the rotation direction in the horizontal plane projection. For the convenience of description, any one of the two limiting bumps 41 is defined as the first limiting bump 41, the limiting block 42 arranged on the first limiting bump 41 is the first limiting block 42, the guiding inclined surface 43 arranged on the first limiting bump 41 is the first guiding inclined surface 43, the other of the two limiting bumps 41 is the second limiting bump 41, the limiting block 42 arranged on the second limiting bump 41 is the second limiting block 42, and the guiding inclined surface 43 arranged on the second limiting bump 41 is the second guiding inclined surface 43. Specifically, the projections of the first limiting bump 41, the limiting block 31 and the second limiting bump 41 on the horizontal plane are arranged in sequence along the rotation direction. The first limiting block 42 is arranged at one end of the first limiting bump 41 away from the first buckle portion 3, and the second limiting block 42 is arranged at one end of the second limiting bump 41 away from the first buckle portion 3;Preferably, when assembling the stirring knife group 1, the stirring knife seat 12 is sleeved outside the transmission section 22 through the driving hole 13, and the lower end of the stirring knife seat 12 abuts against the elastic limiting ring 6. When the stirring motor drives the driving rotating shaft 2 to rotate, the driving rotating shaft 2 drives the first buckling part 3 to rotate relative to the stirring knife seat 12, so that the limiting block 31 abuts against the first guiding inclined surface 43. Under the guiding action of the first guiding inclined surface 43, the first limiting convex block 41 is connected with the limiting groove 32 in a matching manner. At the same time, the limiting block 31 can drive the stirring knife seat 12 to move downward to press the elastic limiting ring 6, so that the elastic limiting ring 6 is in interference fit between the lower end of the stirring knife seat 12 and the upper end of the driving section 21, driving the stirring knife seat 12 to be stably connected to the driving rotating shaft 2 to avoid situations such as detachment. And by the limiting block 31 abutting against the first limiting stop block 42, the rotation amplitude of the driving rotating shaft 2 relative to the stirring knife seat 12 is limited, so that the limiting block 31 drives the stirring knife seat 12 to rotate by pushing the first limiting stop block 42, thereby automatically locking the stirring knife group 1 to the driving rotating shaft 2. Furthermore, by using the cooperatively connected first buckling part 3 and the second buckling part 4 as a positioning reference, the stirring knife group 1 and the driving rotating shaft 2 are driven to be relatively stationary and rotate synchronously, realizing the optimization of the installation steps of the stirring knife group 1, preventing the stirring knife group 1 from shaking or falling off during use. When the stirring motor stops rotating, under the action of inertia, the stirring knife group 1 will continue to rotate along the rotation direction, driving the driving rotating shaft 2 to rotate relative to the stirring knife seat 12 again. Specifically, the first limiting convex block 41 disengages from the limiting groove 32, and then the limiting block 31 abuts against the second guiding inclined surface 43. Under the guiding action of the second guiding inclined surface 43, the second limiting convex block 41 is connected with the limiting groove 32 in a matching manner. At the same time, the limiting block 31 drives the stirring knife seat 12 to move downward to press the elastic limiting ring 6 again, so that the elastic limiting ring 6 is in interference fit between the lower end of the stirring knife seat 12 and the upper end of the driving section 21, driving the stirring knife seat 12 to be stably connected to the driving rotating shaft 2 to avoid situations such as detachment. And by the limiting block 31 abutting against the second limiting stop block 42, the re-cooperatively connected first buckling part 3 and the second buckling part 4 are used as a new positioning reference, so that the stirring knife group 1 and the driving rotating shaft 2 are re-relative to be stationary, thereby preventing the stirring knife group 1 from falling off the driving rotating shaft 2 under the action of inertia and ensuring that the stirring knife group 1 is reliably fixed on the driving rotating shaft 2, improving the safety performance of the equipment.;
