Description

Instructions Knife with knife sharpener Technical field

The invention belongs to the technical field of daily necessities, and relates to a cutting board, in particular to a cutting board with a sharpener. Background technique

The tool is a commonly used tool. When the tool is used for a period of time, the blade will wear and become dull, affecting the cutting efficiency, and the use effect will be poor. At this point, the blade needs to be sharpened to restore the tool performance.

Nowadays, people usually use the tool directly on the grindstone to grind the knife. This method of sharpening is not only inefficient, but also has high technical requirements for sharpening and has potential safety hazards. At the same time, these grindstones need a certain storage space. Whenever they need to be used, they need to take out the grindstone from the storage place, clean it, and then wash it and put it back in place for storage. This makes the sharpening of the knife inconvenient and time consuming.

Some people have designed various sharpening devices for this problem. For example, Japanese Patent Publication discloses a cutting board having a sharpening function [Publication No.: JP2006159395]. According to the process technology and graphic display, it assembles a seesaw or a water hammer paper on the use surface of the cutting board, so that it is ground. The powder of stone powder, sand powder and sharpening knife produced during the knife process is easy to be stained on the board surface, which is difficult to clean. When cutting food such as fish and meat, it affects food hygiene and endangers human health.

Still another person invented a cutting board with a kitchen knife sharpening machine [Publication No.: JP2005334577], according to the process technology and graphic display, it has a groove extending to the cutting board surface of the cutting board at the side of the cutting board, the groove A sharpener consisting of a grinding blade is mounted inside. During the use of the sharpening machine, the powder will accumulate in the groove of the cutting board. It is very difficult to clean. Long-term sharpening will cause metal powder to accumulate in the groove, which will produce bacteria. When cutting vegetables, it will pollute the food hygiene, and the powder will harm. Human health.

There is also a cutting board with a sharpener [Publication No.: US2009/0166943A 1 ]. From the process technology and graphic display, the sharpener is cross-locked on the cutting board by the plate body and the blade insert, if the grinding blade is detached The chopping block combination will not form a sharpener, so the sharpener has no independent function. At the same time, the shape of the cutting board formed by the card joint is poor overall, not beautiful enough, and not strong enough. The sharpener is not independent and is fixed by being snapped onto the board. When the cutting board encounters gravity to cut food, high temperature and low temperature or dishwasher cleaning, the card setting is easy to loose, and the sharpening head is easy to fall off during the use of the sharpening knife, which may cause the tool to damage the body or objects. And this sharpener has only one blade of sharpening material, will be two The blades are crossed into wedge-shaped sharpening slots. Therefore, there is only one function grinding blade. When the technique of the sharpener is not standardized or the two blades on the sharpener are worn and become dull, the blade of the user who grinds more than 70% must have a rough edge. When cutting food such as fish and vegetables, it is easy to cause the burrs to fall off and stick to the food. In use, the metal burrs also enter the human body with the food, which is extremely harmful and affects life and health. Summary of the invention

SUMMARY OF THE INVENTION An object of the present invention is to provide a cutting board with a sharpener which is convenient, has a good sharpening effect, and is highly hygienic, in view of the above problems in the prior art.
