Description

Technical Field

[0001] The invention relates to the technical field of kitchenware, in particular to a multifunctional knife sharpener. Background Art

[0002] At present, among the common kitchen utensils, there are only chopstick racks, but no racks for storing knives. After using the knives, they can only be placed on the chopping board or table, which is easy to touch and cause accidental injury, so the risk factor is high. Since there is no suitable place to put the knives, they will appear untidy, affect the appearance, and take up space. In addition, kitchen knives usually become blunt after a period of use and need to be sharpened. Generally, a whetstone is used, and the knife sharpener holds the knife and moves back and forth directly on the whetstone for manual grinding. This method is inefficient, labor-intensive, and has certain risks. In addition, the sharpness of the knife after grinding, the service life after grinding once, and the loss of the knife after each grinding are all affected by the skill level of the knife sharpener.

[0003] In view of the above defects, there are racks on which knives, chopsticks and cutting boards can be placed in the prior art. Although the racks can store knives, chopsticks and cutting boards, when placing cutting boards on the prior art racks, the cutting boards are generally inserted into corresponding fixed grooves of the racks. Since the widths and thicknesses of the cutting boards are different, cutting boards whose widths and thicknesses are greater than the grooves cannot be inserted into the corresponding cutting board grooves, so the cutting boards cannot be placed on the racks. In addition, there are knife sharpeners in the prior art that use rotating grinding wheels for grinding. Although this type of knife sharpener can improve the efficiency and quality of knife sharpening, this type of knife sharpener is either separately provided from the rack on which knives, chopsticks and cutting boards can be placed, which is inconvenient to use with a relatively single function, or the knife sharpener is fixed on the rack, which is inconvenient to operate and affects the efficiency and quality of knife sharpening.

By co-arranging the storage rack and the sharpening device 6, the sharpening device can be flexibly moved out and stored according to the use environment, which is beneficial to the coordinated use of the storage rack and the sharpening device 6, enhances the overall functionality, facilitates the sharpening operation and dust protection, and can effectively improve the efficiency and quality of sharpening.

[0022] In this embodiment, the knife sharpening device 6 includes a shell 61, the shell 61 is provided with a motor 62, and the output shafts at both ends of the motor 62 are provided with knife sharpening wheels 63. The position of the shell 61 corresponding to the knife sharpening wheel 63 is provided with a knife sharpening groove. A circuit board electrically connected to the motor 62 is also provided in the shell 61. A micro switch 64 electrically connected to the circuit board is provided on one side of the shell 61. Both ends of the inner wall of the storage cover 5 are provided with top blocks 65 used in conjunction with the micro switch 64. The top block 65 is a triangular structure protruding from the outside to the inside. One end of the output shaft of the motor 62 is also connected to a fan blade 66 and a knife sharpening wheel 67. When the knife sharpening device 6 is connected from both sides of the storage cover 5 When the end of the knife sharpening device 6 is extended, the micro switch 64 will be pushed open by the triangular structure protruding from the outside to the inside, so that the motor 62 can drive the knife sharpening wheel 63 to rotate and sharpen the knife. When the knife sharpening device 6 needs to be moved into the storage cover 5 after sharpening, the micro switch 64 will move back with the knife sharpening device 6 and be disconnected from the triangular structure protruding from the outside to the inside. The micro switch 64 rebounds and closes, the motor 62 is powered off, and the knife sharpening wheel 63 stops rotating, until the knife sharpening device 6 is retracted to a suitable position in the storage cover 5. In addition, one end of the output shaft of the motor 62 is also connected to a fan blade 66 and a knife sharpening wheel 67, and the fan blade 66 can achieve the effect of dissipating heat for the knife sharpening wheel 63 and the kitchen knife.
