Detailed implementation mode

[0025] For better understanding and implementation, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the attached drawings in the embodiments of the present utility model.

[0026] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the attached drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0028] An embodiment of the present utility model discloses a detachable cutter assembly, which can be specifically referred to Figures 1 - 5 , and this detachable cutter assembly specifically includes a cutter group 10, and the cutter group 10 includes a cutter holder support and a blade 102 fixed on the cutter holder support.

[0029] This detachable cutter assembly also specifically includes a cutter head assembly 20, and the cutter head assembly 20 includes a cutter head body and a driving shaft 204 fixed on the cutter head body. The cutter holder support and the driving shaft 204 are inserted and fixed, and the cutter holder support and the cutter head body are magnetically fixed.

[0030] In view of the problem that the existing stirring cutter falls off and flies out due to inertia, in addition to the insertion and fixation of the cutter holder support and the driving shaft 204, this detachable cutter assembly also additionally sets the magnetic fixation between the cutter holder support and the cutter head body, and uses the suction force between the two to maintain the suction between the cutter group 10 and the cutter head body, preventing the blade 102 from falling off during high-speed rotation and improving safety. Moreover, the cutter group 10 can be detached from the cutter head assembly 20, which is also convenient for separately removing the cutter group 10 for cleaning, and the cutter head assembly 20 does not need to be disassembled, so it is not easy to get water.

[0031] In summary, the detachable knife assembly utilizes the magnetic attraction principle to achieve the suction and fixation of the knife group 10, which can prevent the danger that the knife group 10 is not placed in place due to local friction after the user puts it in, and the user does not actively press and assemble the knife group 10 in place, resulting in the blade 102 flying out, thereby improving the overall safety.

[0032] In one optional embodiment, a magnet 202 is provided inside one of the knife seat bracket and the knife disc body, and the other is made of a magnetic material. With this setting, the structure is simple, convenient for manufacturing and production, and the production difficulty is reduced.

[0033] For example, a magnet 202 can be provided inside the knife seat bracket, and the knife disc body is made of a magnetic material. Or, as shown in the embodiment in the figure, a magnet 202 can be provided inside the knife disc body, and the knife disc body is made of a magnetic material.

[0034] In one optional embodiment, the knife seat bracket includes a knife seat upper bracket 103 and a knife seat lower bracket 101 which are inserted into each other. The knife seat lower bracket 101 is arranged between the knife seat upper bracket 103 and the knife disc body, and the blade 102 is fixed between the knife seat upper bracket 103 and the knife seat lower bracket 101. With this setting, the blade 102 can be stably fixed specifically through the knife seat upper bracket 103 and the knife seat lower bracket 101, thereby improving the overall structural stability.

[0035] Specifically, a magnet 202 is provided inside the knife disc body, and the knife seat lower bracket 101 is made of a magnetic material.

[0036] In one optional embodiment, in order to achieve better magnetic attraction force, the magnetic material is a non-magnetic iron material. For example, the knife seat lower bracket 101 is made of a non-magnetic iron material. For example, stainless steels starting with 4, such as stainless steel 409, stainless steel 410, stainless steel 430 or stainless steel 444, etc., have strong magnetism and anti-rust performance.

[0037] In one optional embodiment, a boss 2011 is convexly provided on the end face of the knife disc body facing the knife group 10, the drive shaft 204 is fixed on the boss 2011, and a magnet 202 is provided inside the boss 2011. With this setting, a convex boss 2011 structure is provided on the knife disc body, and then the magnet 202 is provided inside the boss 2011 structure, which can make the overall structure more compact and can well control the overall size.

[0038] In one optional embodiment, let the end face of the magnet 202 facing the tool holder bracket be the top surface, and let the end face of the tool disc body facing the tool holder bracket be the top surface. The range of the distance D1 between the top surface of the magnet 202 and the top surface of the tool disc body is: 0.6 mm ≤ D1 ≤ 3 mm. With such a setting, it can not only ensure enough space to assemble the magnet 202, but also prevent the boss 2011 from protruding too much, resulting in the blade 102 being too high and not being good at cutting food materials.

[0039] For example, the distance D1 between the top surface of the magnet 202 and the top surface of the tool disc body can be 0.6 mm, 0.8 mm, 1 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, 2 mm, 2.2 mm, 2.4 mm, 2.6 mm, 2.8 mm or 3 mm. Or, the distance D1 between the top surface of the magnet 202 and the top surface of the tool disc body can also be other values within the range of 0.6 mm ≤ D1 ≤ 3 mm.

[0040] In one optional embodiment, a boss 2011 is protrudingly provided on the end face of the tool disc body facing the tool group 10, and the drive shaft 204 is fixed to the boss 2011. The range of the height H1 between the opposite end faces of the boss 2011 and the tool holder bracket is: 1 mm ≤ H1 ≤ 5 mm. With such a setting, if it is less than 1 mm, the safety distance is insufficient, and there is a risk that the lower tool holder bracket 101 will rub against the tool disc body; if the distance is greater than 5 mm, it is easy to cause insufficient magnetic force and insufficient preloading pressure of the tool group 10. Therefore, the height H1 between the opposite end faces of the boss 2011 and the tool holder bracket is optimally 1 mm ≤ H1 ≤ 5 mm.

[0041] For example, the height H1 between the opposite end faces of the boss 2011 and the tool holder bracket can be 1 mm, 2 mm, 3 mm, 4 mm or 5 mm. Of course, the height H1 between the opposite end faces of the boss 2011 and the tool holder bracket can also be other values within the range of 1 mm ≤ H1 ≤ 5 mm.

[0042] In one optional embodiment, a waterproof oil seal 203 is provided between the magnet 202 and the drive shaft 204 to prevent lubricating oil from leaking from the machine gap.

[0043] In one optional embodiment, let the end of the lower tool holder bracket 101 facing the tool disc body be the bottom. The bottom of the lower tool holder bracket 101 is cylindrical, and the diameter of the bottom of the lower tool holder bracket 101 is greater than 15 mm. Since the waterproof oil seal 203 is a standard part and its diameter is 15 mm, the minimum inner diameter of the magnet 202 will be limited to 15 mm. If the bottom size of the upper lower tool holder bracket 101 is less than 15 mm, it is easy to have the problem of insufficient magnetic force. Therefore, the diameter of the bottom of the lower tool holder bracket 101 being greater than 15 mm can achieve better magnetic attraction.

[0044] In one optional embodiment, the circumferential outer side of the driving shaft 204 is provided with an edge, and the tool holder bracket is provided with a driving hole 1011 matching the driving shaft 204, and the driving hole 1011 is provided with corners corresponding to the edge to drive the tool assembly 10 to rotate.

[0045] Specifically, the driving shaft 204 is provided with a plurality of edges extending in the vertical direction, the plurality of edges are deflected in the circumferential direction of the driving shaft 204, the deflection direction of the plurality of edges from top to bottom is opposite to the rotation direction of the knife group 10, and the plurality of edges and corners extending in the vertical direction in the driving hole 1011. Therefore, the edges abut against the edges and corners, and the abutting force generated by the edges on the edges and corners has a downward component force, that is, the edges deflected in the circumferential direction have a downward limiting effect on the knife group 10, so that the knife group 10 cannot be axially separated from the driving shaft 204 upward during high-speed rotation.

[0046] The embodiment of the utility model also discloses a food processor, including the above-mentioned detachable knife assembly. It can be seen that in addition to the knife seat bracket and the drive shaft 204 being plugged and fixed, the food processor also additionally provides a knife seat bracket and a knife disc body for magnetic fixation, and uses the suction force between the two to maintain the suction between the knife set 10 and the knife disc body, preventing the blade 102 from falling off when running at high speed, thereby improving safety. In addition, the knife set 10 can be detached from the knife disc assembly 20, which is also convenient for removing the knife set 10 separately for cleaning, and the knife disc assembly 20 does not need to be disassembled, so it is not easy for water to enter.

[0047] In one optional embodiment, the food processor may be a wall breaking machine, a soy milk machine or a juicer.

[0048] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
