However, as the demands of people for food processing are continuously improved and the demands for convenience in use of the food processor are gradually improved, people hope that the food processor can process and crush the food with higher hardness such as nuts, and the like, so that the higher demands are provided for the hardness of the blade.

To solve this problem, manufacturers generally use a plating process to form a metal coating on the surface of the blade, and the coating material is generally titanium, chromium, carbon, or their nitrides. The coating is attached to the surface of the blade through physical vapor deposition, so that a good protective layer is formed, and the hardness of the blade is improved.

However, although the strength of the blade is greatly improved by the protection of the plating layer, the rotation speed of the blade is very high during the processing, particularly the linear speed at the tip of the blade is very high. Therefore, when the blade cuts food materials or water flow, the food materials and the water flow can produce great resistance to the blade, the resistance can cause liquid in the processing cavity to generate turbulence, and then the blade can generate vertical vibration, so that the rotating speed of the blade and the installation firmness of the blade are influenced, and the cutting and crushing effects of the blade are greatly influenced.

Specifically, as shown in fig. 1, the flow direction of the liquid is opposite to the rotation direction of the blade 1, for example, when the blade 1 rotates clockwise, the liquid flows counterclockwise with respect to the blade 1.

It should be noted that the array of the contact grooves 14 is not particularly limited, and may be a rectangular array, an array along a certain path, or a circular array.

In the cutter of the utility model, when the cutter moves, the blade 12 contacts food and liquid to cut, the cut liquid flows to the contact surface 13 by the guide of the blade 12 and flows along the contact surface 13, the contact surface 13 is provided with the contact groove 14, so when the liquid flows through the contact surface 13, the liquid enters the contact groove 14, a water film 141 (water medium layer) is formed on the surface of the contact groove 14, the water film 141 has better lubricity because of being fluid, when the cutter contacts with the upper liquid flow layer 142, the relative friction force between the liquid flow layer 142 and the water film 141 is small, the resistance between the liquid flow layer 142 and the blade 1 is greatly reduced, and the blade 1 does not generate lateral component force on the liquid flow layer 142, so that the turbulent flow is not caused. Thus, the liquid flow layer 142 in the processing cavity is also a relatively stable laminar flow, so that the resistance and disturbance to the blade 1 rotating at a high speed can be greatly reduced, the vibration of the cutter can be avoided, the stability of the cutter is improved, and meanwhile, the rotation efficiency of the cutter and the crushing effect on food materials are also ensured.

The liquid cut by the blade 1 is liquid in a processing cavity of the food processor, and may be clear water or food slurry (such as soybean milk, mi Hu, etc.).

As a preferred embodiment of the utility model, the roughness of the inner wall of the contact recess 14 is greater than the roughness of the contact surface 13.

The surface of the contact groove 14 is rough, and thus has better affinity with the liquid, the contact groove 14 is easy to wet, that is, when the liquid flows through, a layer of water film 141 is more easily formed on the surface of the contact groove 14, so that the liquid is further ensured to smoothly slide through the contact surface 13, and the flow of the liquid is ensured to be a stable laminar flow.

Specifically, during the machining, the surface of the contact groove 14 may be roughened (sandblasted or polished), and the roughened surface roughness Ra may be between 0.05 and 0.3. The contact surface 13 may be subjected to polishing treatment and then to metal plating treatment. The thickness of the coating is 1-5um, the coating materials are chromium, titanium, carbon and the like and their nitrides, the metal coating can improve the surface hardness of the blade 1, enhance the crushing effect of the blade 1 and prolong the service life.

Preferably, the blade 1 is integrally provided with the contact groove 14, and a part of the contact groove 14 is cut to form the blade edge 12 on one side of the blade 1.

When the blade 1 is machined, the contact groove 14 is machined on the surface of the blade 1, then the side edge of the blade 1 is machined to form the blade edge 12, at this time, the contact groove 14 in the area is cut to disappear or the groove depth is reduced, and the contact groove 14 of the blade ridge 11 is in a complete groove structure.

Because the volume of the contact groove 14 is smaller, and the relative movement speed of the liquid and the blade 1 is faster, the diversion transition surface 145 is arranged on the water inlet side 143, so that the liquid can be guided into the contact groove 14, the drag reduction effect is achieved, and the liquid is prevented from directly crossing the contact groove 14.

In a preferred embodiment, as shown in fig. 3, the water inlet side 143 and the water outlet side 144 are provided with the diversion transition surface 145, the diversion transition surface 145 of the water inlet side 143 is used for guiding the liquid into the contact groove 14, and the diversion transition surface 145 of the water outlet side 144 is used for guiding the liquid in the contact groove 14 to flow out.
