The invention relates to the field of knife sharpener, in particular to a knife sharpener that can sharpen knives simultaneously on rough and fine grinding position of the knife sharpening seat.
With the development of the times and the improvement of people's living standards, the daily traditional tools in the kitchen have been difficult to meet people's daily needs. Traditional grindstones and knife sharpeners are large and unsightly. They are less popular in modern families, and most people do not know how to sharpen knives. Therefore, when household kitchen knives are dull, it is difficult to find a place to sharpen knives or the wrong way to sharpen knife can't achieve the desired sharpness. There are also some knives that cause excessive edge wear due to improper use. The sharpener of the sharpening seat on the market cannot quickly repair the blade, causing certain trouble for people. The result is to change the knife or find someone to sharpen the knife, which brings trouble and increases the cost of living.
At present, many sharpeners are composed of grindstones alone, which are large and unsightly, occupying kitchen space. The structural design is unreasonable, the operation is cumbersome, and certain skills are required. Kitchen knives cannot be sharpened quickly and simply, and it is difficult to satisfy people's handling of ingredients.
The technical problem to be solved for the above problems by the invention is to provide a knife sharpener that can sharpen knives simultaneously on rough and fine grinding position of the knife sharpening seat.
In order to solve the above technical problems, the technical solution provided by the invention is: a knife sharpener that can sharpen knives simultaneously on rough and fine grinding position of the knife sharpening seat, comprising a knife sharpening seat, a cover plate, a knife sharpening groove and a fine grinding column. The upper end of the knife sharpening seat is provided with the cover plate. The lower end of the sharpening seat is provided with a bottom fixing column. The inner bottom surface of the cover plate is provided with two sets of connecting columns. A connecting groove is arranged between the connecting column and the knife sharpening seat. The center position of the knife sharpening seat and the cover plate is correspondingly provided with a knife sharpening groove with notches on both sides. The fine grinding column is installed on the inner side of the sharpening groove on the sharpening seat. A rough grinding plate is set at a position symmetrical to the fine grinding plate based on the center of the cover plate.
As an improvement, the fine grinding column and the rough grinding plate are inlaid on the cover plate. There are two fine grinding columns and two the rough grinding plates and the angle between them is 25°-30°. The angle between the fine grinding columns and the rough grinding plates is on the same horizontal line. In this way, the fine grinding column is used for fine grinding the tool, and the rough grinding plate is used for the rough grinding the tool. They are installed on the inner side of the same sharpening seat, which improves the convenience of use.
As an improvement, the sharpening groove, the bottom fixing column and the connecting groove are integrally formed on the sharpening seat. In this way, the one-piece form ensures stability. In addition, the bottom fixing column facilitates the connection of the external wooden base.
As an improvement, the connecting column is integrally formed on the cover plate. In this way, the connecting column is used for connection.
As an improvement, the fine grinding column is made of ceramic bars, and the rough grinding disc is made of diamond or cemented carbide. In this way, different materials can be used to achieve different sharpening effects.
Compared with the prior art, the beneficial effects of the invention are as follows:
The device is used in combination with the sharpening seat. The included fine grinding position and rough grinding position can be converted on the knife sharpener itself, without taking up too much space of the sharpening seat. Two gears of rough and fine grinding positions of the device can be selected according to the wear degree of the knife blade to carry out the sharpening operation, or the rough and fine grinding positions can be used for sharpening operation at the same time, thereby improving the convenience of operation and occupying very little space.
As shown in the figures: (1) a knife sharpening seat, (2) a cover plate, (3) a knife sharpening groove, (4) a bottom fixing column, (5) a fine grinding column, (6) a rough grinding plate, (7) a connecting groove, (8) a connecting column, (9) a notch.
The invention is further described in detail below according to the attached figures.
During the specific implementation of the invention, embodiment 1 is as follows.
As shown in
Preferably, the fine grinding column (5) and the rough grinding plate (6) are inlaid on the cover plate (2). There are two fine grinding columns (5) and two the rough grinding plates (6) and the angle between them is 25°-30°. The angle between the fine grinding columns (5) and the rough grinding plates (6) is on the same horizontal line. The fine grinding column (5) is used for fine grinding the tool, and the rough grinding plate (6) is used for the rough grinding the tool. They are installed on the inner side of the same sharpening seat (1), which improves the convenience of use. The sharpening groove (3), the bottom fixing column (4) and the connecting groove (7) are integrally formed on the sharpening seat (1). The one-piece form ensures stability. In addition, the bottom fixing column (4) facilitates the connection of the external wooden base. The connecting column (8) is integrally formed on the cover plate (2). The connecting column is used for connection. The fine grinding column (5) is made of ceramic bars, and the rough grinding plate (6) is made of diamond or cemented carbide. Different materials can be used to achieve different sharpening effects.
Working principle: The device has two gears: the fine grinding position composed of the fine grinding column (5) and the rough grinding position composed of the rough grinding plate (6). The two gear grinding positions are kept on the same horizontal line. They can be used simultaneously, or can be used separately. The friction direction of the blade is kept at 45° from the horizontal direction. The knife can be pulled back from the tail of the blade. At the same time, two notches (9) are added to the sharpener, which can increase the integrity of sharpening blade of the tool and increase the applicability of the device. It is suitable for all kinds of knives to be sharpened. The function of the fine grinding position of the fine grinding column (5): finely sharpen the blade, repair the scratches on the blade, smooth the surface, and eliminate the small burrs on the blade. The function of the rough grinding position of the rough grinding plate (6): quickly shape the cutting edge, suitable for blunt knives. When in use, put the end of the knife into the sharpening edge to keep the blade perpendicular to the table and do not sway left and right. Press down with the usual sharpening force and then pull back from the tail of the blade.
In addition, the terms “first” and “second” are only used for describing purposes, and should not be construed as indicating or implying relative importance or implying the number of indicated technical features. Therefore, the features defined with “first” and “second” may expressly or implicitly include one or more of the features.
