Description

Technical Field

[0001] The utility model relates to the technical field of kitchen knife sharpeners, in particular to a grinder for improving the sharpness of kitchen knives. Background Art

[0002] After being used for a period of time, the blade of a kitchen knife will become blunt, so the blade must be sharpened to restore its sharpness. People began to use tools such as grindstones and grinding discs to sharpen knives thousands of years ago. With the passage of time, the technology of kitchen knife sharpening tools has gradually developed and improved.

[0003] With regard to the existing related technologies, the inventors believe that the following defects exist: traditional kitchen knife sharpeners have exposed cutting edges, which often lead to finger cuts and poor safety. In addition, due to the uncertainty of the relative movement between the sharpener and the blade, the tool edge angle that originally conforms to the principles of mechanics is destroyed, thereby reducing the cutting efficiency of the tool. The grinding wheel of the prior art is in the shape of a V-shaped straight line. When a kitchen knife is rubbed between the two grinding wheels, an unpleasant sound will be emitted. Utility Model Content

[0004] In order to solve the technical problem that the existing kitchen knife sharpeners have poor safety due to the exposed cutting edge, which often causes finger cuts, and the uncertainty of the relative movement between the sharpener and the blade causes the tool edge angle that originally complies with the mechanical principle to be destroyed, thereby reducing the cutting efficiency of the tool, and the grinding wheel shape of the prior art is a V-shaped straight line, and when the kitchen knife is rubbed between two grinding wheels, an unpleasant sound will be emitted. The utility model provides a grinder for improving the sharpness of kitchen knives.

DETAILED DESCRIPTION

[0023] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0024] Example: See Figure 1 - Figure 6 A grinder for improving the sharpness of a kitchen knife in this embodiment comprises a grinding assembly 1 and a gripping block 2. The grinding assembly 1 comprises a first grinding wheel 4 and a second grinding wheel 6. A first inclined surface 5 is arranged on the inner side of the first grinding wheel 4, a second inclined surface 7 is arranged on the inner side of the second grinding wheel 6, an insertion port 20 is arranged between the first inclined surface 5 and the second inclined surface 7, a back plate 8 is arranged on the outer side of the first inclined surface 5 and the second inclined surface 7, a nut 9 is fixedly connected to one side of the back plate 8, a shaft 10 is fixedly connected to one end of the nut 9, and a storage groove 14 is processed on the top of the gripping block 2. Two pressing blocks 3 are arranged on the top of the gripping block 2. The first grinding wheel 4 and the second grinding wheel 6 are formed into a curve shape that bulges slightly outward, so that the contact portion between the tip of the kitchen knife and the first inclined surface 5 and the second inclined surface 7 is extremely narrow, and the kitchen knife is ground closely with the grinding wheel. The kitchen knife is inserted into the insertion port 20 with exactly the same touch as the natural abrasive tool grinding, which has the advantage of reliably grinding the tip of the knife in a short time. Since the first grinding wheel 4 and the second grinding wheel 6 are in a curve shape that bulges slightly outward, when the tip of the knife is ground, the wear of the grinding wheel is significantly reduced compared with previous products.

[0025] When the kitchen knife needs to be sharpened, first hold the holding block 2 with the left hand, and insert the kitchen knife between the first grinding wheel 4 and the second grinding wheel 6 through the insertion port 20 with the right hand, then adjust the position of the pressing block 3, and press the pressing block 3 downward, and fix the pressing block 3 by tightening the bolt 17, and then press the kitchen knife handle held by the right hand to the left, so that the left side of the kitchen knife is closely attached to the first inclined surface 5 of the first grinding wheel 4, on the contrary, the right side of the kitchen knife and the blade are closely attached to the second inclined surface 7 of the second grinding wheel 6 on the right side, while maintaining the above state, the kitchen knife held in the right hand only needs to make 2 to 3 reciprocating movements, and the blade will be ground;

[0026] Furthermore, the first grinding wheel 4 and the second grinding wheel 6 are placed opposite to each other, and the first grinding wheel 4 and the second grinding wheel 6 are inclined, and the first inclined surface 5 and the second inclined surface 7 are formed into a truncated cone shape by diamond powder. When grinding the circular knife, one side of the knife tip will fit with the first inclined surface 5 or the second inclined surface 7, and the first inclined surface 5 and the second inclined surface 7 located above the knife tip are used for grinding, so that the knife tip of the circular knife can be ground more conveniently;

[0027] Furthermore, the tops of the two pressing blocks 3 are respectively provided with elongated holes 16, the pressing blocks 3 are movably connected to the top of the gripping block 2, the tops of the elongated holes 16 are provided with bolts 17, the bottoms of the bolts 17 are threadedly connected with the fixing blocks 15, the bottoms of the fixing blocks 15 are fixedly connected to the tops of the gripping blocks 2, the fixing blocks 15 are movably connected inside the elongated holes 16, when the pressing blocks 3 need to be fixed, the bolts 17 are tightened so that the bolts 17 are in contact with the tops of the pressing blocks 3, thereby limiting the movement of the pressing blocks 3;

[0028] Furthermore, two support blocks 11 are arranged on both sides of the storage slot 14, and the support blocks 11 are in an inclined state, one side of the support block 11 is fixedly connected with an insert frame 12, one end of the shaft rod 10 passes through one side of the support block 11, and one end of the shaft rod 10 is located inside the insert frame 12, and the angle formed by the axis of the shaft rod 10 and the top of the grip block 2 is 30 degrees, so that the kitchen knife is tilted at a certain angle with the pressing block 3 when grinding, which is more convenient for people's use habits, thereby saving more effort;

[0029] Furthermore, a prevention valve 13 is provided on the upper part of the insert frame 12, and the insert frame 12 is located at the bottom of the prevention valve 13. By providing the prevention valve 13, the prevention valve 13 limits the movement of the shaft 10, and prevents the movement range of the shaft 10 from increasing, thereby preventing the first grinding wheel 4 and the second grinding wheel 6 from being unstable when grinding the kitchen knife, which helps to dramatically improve the grinding quality of the kitchen knife.

[0030] Furthermore, a lower cover 18 is provided at the bottom of the gripping block 2, and a plurality of feet 19 are fixedly connected around the bottom of the gripping block 2. Anti-skid pads are provided at the bottom of the feet 19 to prevent the gripping block 2 from sliding during grinding.

[0031] Working principle: When in use, first hold the holding block 2 with the left hand, and insert the kitchen knife between the first grinding wheel 4 and the second grinding wheel 6 through the insertion port 20 with the right hand, then fix the pressing block 3, and then press the kitchen knife handle held by the right hand to the left, so that the left side of the kitchen knife is tightly against the first inclined surface 5 of the first grinding wheel 4. While maintaining the above state, the kitchen knife held in the right hand only needs to make 2 to 3 reciprocating movements, and the blade will be ground. The kitchen knife that chefs usually grind for about 10 minutes can be ground in just 2 or 3 seconds, and it can be used by relevant personnel of general households, restaurants, and food kiosks.

[0032] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
