Description

Technical Field

[0001] This utility model relates to the field of knife sharpeners, specifically an automatic knife sharpener. Background Technology

[0002] A knife sharpener is a grinding tool used to repair and sharpen the cutting edges of knives to restore their sharpness. Most mainstream products on the market are manual sharpeners. Users place the blade into the grinding groove and pull it back and forth, sharpening the edge through friction. To effectively control the heat generated during sharpening and promptly remove grinding debris to maintain the cutting force of the whetstone, water must be continuously added for cooling and cleaning. This method is not only cumbersome but also highly dependent on the user's feel and angle control, thus posing a significant learning curve for beginners. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0016] Please refer to Figure 1 , Figure 2This embodiment provides an automatic knife sharpener, including a housing 1 and a sharpening assembly. The housing 1 has a knife inlet 2, a water outlet 3, a water inlet 4, and a switch 5. Inside the housing 1 are the sharpening assembly, a stroke assembly, a water pump 6, and a circuit board. The sharpening assembly is movably fixed inside the housing 1 via the stroke assembly. The sharpening assembly includes a base 7, with at least two grinding wheels 8 on the top of the base 7. The two grinding wheels 8 are arranged opposite each other and run relative to each other, sharpening both sides of the knife edge downwards. A support member 9 is provided in the middle of the grinding wheels 8 to support the knife edge. Two motors 110 are provided inside the base 7. The two motors 110 drive the grinding wheels 8 to rotate through a transmission component. The transmission component 11 is a pulley or a gear 12. The stroke assembly is a gear 12 and rack 13 / nut and screw / belt and pulley. In this embodiment, gear 12 and rack 13 are preferred. Rack 13 is provided at the bottom of the housing 1. Motor II 14 and rotating shaft 15 are provided at the bottom of the base 7. Gear 12 is provided on both sides of the rotating shaft 15. Gear 12 and rack 13 mesh with each other. Motor II 14 drives rotating shaft 15 to rotate, so that the grinding assembly moves back and forth in the housing 1. A bracket 16 is provided at the beginning and end of the stroke assembly. A torsion spring 17 is provided at the bottom of the bracket 16. When the torsion spring 17 is in the natural state, the bracket 16 is in an inclined state. The water outlet pipe 18 of water pump 6 is connected to the base 7. Two water outlet pipes 18 branches off from the end of the water outlet pipe 18. The water outlet pipes 18 are respectively aligned with the two grinding wheels 8. The suction pipe 19 is in contact with the bottom of the housing 1. Switch 5 controls the opening and closing of motor I 10, motor II 14 and water pump 6 through circuit board.

[0017] This embodiment provides an automatic knife sharpener. In use, water is poured into the housing 1 through the water inlet 4. The blade is aligned with the knife insertion inlet 2 and inserted into the housing 1, connecting it between the two grinding wheels 8. The blade abuts against the support member 9 and the top of the bracket 16. The sharpener is started, and the circuit board controls the motor I10 to drive the grinding wheels 8 to rotate in opposite directions, so that the grinding wheels 8 grind the blade. The circuit board controls the water pump 6 to draw water from the housing 1 through the suction pipe 19 and spray water onto the grinding wheels 8 through the outlet pipe 18. The circuit board controls the motor II14 to make the sharpening assembly move back and forth in the housing 1, ensuring that the grinding wheels 8 can grind all parts of the blade. When the sharpening assembly moves to the bracket 16, the sharpening assembly will push the bracket 16 from an inclined state to a vertical state. At this time, the support member 9 replaces the bracket 16 to support the blade. After the sharpening assembly moves away, the bracket 16 returns to the inclined state under the action of the torsion spring 17. The bracket 16 and the support member 9 cooperate to ensure that the grinding wheels 8 grind the blade at all times.

[0018] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various changes and modifications can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
