[0026] The knife sharpener with different sharpening angles or functions can be selected comprises a lower shell 1 and an upper cover 2. The upper cover 2 is a hollow structure and is snapped onto the upper part of the lower shell 1. An installation cavity is formed between the lower shell 1 and the upper cover 2.

[0027] The lower shell 2 and the upper cover 1 can be made of high-strength, rust-proof and corrosion-resistant materials such as metal or engineering plastics to avoid damage caused by oil fume pollution in the kitchen and extend the service life.

[0028] The lower shell 1 and the upper cover 2 are assembled by snapping together, and can be assisted by screws for locking to prevent them from coming apart during use.

[0029] The bottom of the lower shell 1 is set to be flat, which is convenient for being placed on a table for use. An anti-skid pad in the form of a rubber sticker or rubber package can also be set on the bottom to prevent sliding during use.

[0030] A sharpening seat 3 is arranged at the front end of the inner cavity of the installation cavity, and a plurality of first sharpening grooves 4 are opened on the top of the sharpening seat 3. A sharpening disk 5 is rotatably arranged on the rear side of the inner cavity of the installation cavity, and a plurality of second sharpening grooves 6 are arranged at intervals on the outer annular surface of the sharpening disk 5. Sharpening members with different angles are respectively arranged in the plurality of first sharpening grooves 4 and the plurality of second sharpening grooves 6.

[0031] The sharpening members arranged in the multiple first sharpening grooves 4 respectively form a certain sharpening angle, which can meet the sharpening requirements of most common knives. The sharpening members in the second sharpening grooves 6 form multiple other different sharpening angles. The sharpening angles in each sharpening groove are different from each other, which can meet the sharpening requirements of a small number of special knives.

[0032] The sharpening members in the plurality of second sharpening grooves 6 can be sharpening members with the same angle and different forms. For example, the sharpening members in two second sharpening grooves 6 have the same angle, but the sharpening members are in the form of a sheet and a column, or in the form of fine grinding and fine grinding. The sharpening members can also be sharpening members with different angles and forms.

[0033] Knife sharpening materials in the form of coarse grinding, fine grinding, precision grinding, single-edged knife sharpening, scissors sharpening, etc. can also be assembled as needed, or sharpening grooves for flexible grinding and knife maintenance, and grooves for scissors sharpening can be added to increase the different functions of the sharpener to enhance the user experience and expand the scope of use.

[0034] The opening angle of each second sharpening groove 6 is also different to correspond to the sharpening angle of the internal sharpening member, so as to facilitate the cutting edge of the tool to extend into the second sharpening groove 6 and contact the sharpening member.

[0035] The upper cover 2 is provided with a plurality of first notches 7 and a second notch 8 corresponding to the first grinding grooves 4 one by one, and the grinding disc 5 is rotated so that one of the second grinding grooves 6 is corresponding to the second notch 8 for grinding.

[0036] The opening angle of the second notch 8 is greater than the opening angle of the second grinding groove 6 with the largest opening angle, so that when any second grinding groove 6 and the second notch 8 are in the working position correspondingly, the tool can be normally inserted for grinding.

[0037] The number of the second grinding grooves 6 can be 3-6.

[0038] A knob 9 for driving the knife sharpening disc 5 to rotate is arranged in the installation cavity.

[0039] The knob 9 is made of silicone, has a good hand feel and is not prone to mold.

[0040] The upper cover 2 is provided with a through slot, and the edge of the knob 9 extends to the outside of the upper cover 2 through the through slot.

[0041] The edge of the knob 9 extends to the outside of the upper cover 2, which is convenient for adjustment by rubbing with fingers. A transmission assembly is arranged in the installation cavity, and the transmission assembly is driven by the knob 9 to drive the sharpening disc 5 to rotate, so as to select the appropriate second sharpening groove 6 for sharpening.

[0042] The inner cavity of the installation cavity is provided with a hollow support frame 12 with an open top. A support column 13 is transversely fixedly connected between the two side walls of the support frame 12, and the sharpening disc 5 is rotatably sleeved on the support column 13.

[0043] The support frame 12 is fixedly connected to the top of the lower shell 1 and is divided into left and right sides.

[0044] The sharpening disc 5 rotates with the support column 13 as the axis to adjust and select the second sharpening groove 6.

[0045] The axis of the knife grinding disc 5 is arranged as a hollow structure which is nested in the surface of the support column 13. The outer ring surface of the support column 13 is provided with a plurality of grooves at intervals. The inner ring surface of the knife grinding disc 5 is provided with a mounting groove 11. The mounting groove 11 is provided with an elastic positioning block which extends into the central cavity of the knife grinding disc 5. When the elastic positioning block is inserted into a groove, the angle of the knife grinding disc 5 is positioned.

[0046] When the knife sharpening disc 5 rotates, the elastic positioning block moves outward from the groove and is gradually compressed so that it sinks into the mounting groove 11, so that the knife sharpening disc 5 can rotate a certain angle relative to the support column 13. When the rotation continues, the elastic positioning block passes over multiple grooves until it rotates to a suitable angle, and the mounting groove 11 corresponds to a groove. At this time, the elastic positioning block is reset under the action of elasticity, enters the corresponding groove and clamps, thereby positioning the knife sharpening disc 5 so that a second knife sharpening groove 6 just corresponds to the second notch 8, and it will not rotate at will during the knife sharpening process.

[0047] When any second grinding groove 6 and the second notch 8 are relatively moved into the working position, the elastic positioning block is just inserted into a groove for positioning.

[0048] Other positioning mechanisms may also be used to position the sharpening disc 5 .

[0049] A rotating shaft is rotatably provided in the support frame 12, the knob 9 is fixedly sleeved on the surface of the rotating shaft, a driving gear 17 is provided on one side of the knob 9, a transmission gear 14 is provided in the support frame 12, and a driven gear 18 is provided on one side of the sharpening disk 5. The driving gear 17 drives the driven gear 18 to rotate through the transmission gear 14.

[0050] The driving gear 17, the transmission gear 14 and the driven gear 18 form a transmission assembly. When the knob 9 is rotated, the driving gear 17 is driven to rotate, thereby driving the transmission gear 14 to rotate, and then driving the driven gear 18 to rotate, and finally driving the sharpening disc 5 to rotate, selecting the appropriate second sharpening groove 6 for sharpening.

[0051] The arrangement position of each component can be adjusted and installed according to the space size in the installation cavity and the size of the parts to ensure that each component can operate normally without interfering with each other. The knob 9 should be located near the handle side of the device as a whole to avoid cuts during use.

[0052] A rotating rod is disposed inside the support frame 12, and the transmission gear 14 is rotatably connected to the support frame 12 via the rotating rod to achieve the rotation effect.

[0053] Patterns, numbers and other marks can be drawn on the surface of the knob 9, which correspond to multiple second sharpening grooves 6 respectively. When a second sharpening groove 6 corresponds to the second notch 8 and is in the working position, the corresponding mark on the knob is located at the top of the knob 9 for easy observation, so as to determine that the second sharpening groove 6 to be used is adjusted into place, which is convenient for adjustment and selection.

[0054] The driving gear 17 and the driven gear 18 can also be driven by a gear belt, thus eliminating the transmission gear 14. The driving gear 17 and the driven gear 18 can also be replaced by pulleys and driven by a silicone belt or a belt drive.

[0055] The lower shell 1 is provided with a gripping groove 10 for easy gripping and fixing to prevent movement during use.

[0056] The working principle of the knife sharpener with different knife sharpening angles or functions provided by the utility model is as follows:

[0057] When the knob 9 is rotated, the driving gear 17 is driven to rotate, thereby driving the transmission gear 14 to rotate, and then driving the driven gear 18 to rotate, and finally driving the sharpening disc 5 to rotate. When the sharpening disc 5 rotates, the elastic positioning block moves from the groove to the outside and is gradually compressed, so that it is immersed in the installation groove 11, so that the sharpening disc 5 can rotate a certain angle relative to the support column 13. When it continues to rotate, the elastic positioning block passes over multiple grooves until it rotates to a suitable angle 5, and the installation groove 11 corresponds to a groove. At this time, the elastic positioning block is reset under the action of elasticity, enters the corresponding groove and clamps, thereby positioning the sharpening disc 5, so that a second sharpening groove 6 just corresponds to the second notch 8, enters the working position, and selects different sharpening grooves to sharpen the tool.

[0058] Compared with the related art, the knife sharpener provided by the utility model with the option of different knife sharpening angles or functions has the following beneficial effects:

[0059] The plurality of first sharpening grooves 4 and the plurality of second sharpening grooves 6 can be provided with sharpening members having different angles and forms, and the plurality of sharpening functions are concentrated in one disc body for selection and use in the form of a knob. By turning the knob 9, the sharpening disc 5 is driven to rotate, so that the different second sharpening grooves 6 are moved to the position corresponding to the second notch 8, and different second sharpening grooves 6 are selected for use, so that the entire device can simultaneously have a plurality of sharpening members of different angles and forms, which can be freely selected according to the cutting edge angle of the tool, and can meet the sharpening needs of a variety of tools. While being able to select a plurality of different sharpening angles for sharpening, the grinding function and other functions such as scissors sharpening can also be added to the same sharpener for use together, so as to enrich the versatility of the product and increase the different types of sharpening needs of users.
