Abstract
Description
Technical Field
[0001] This utility model relates to a knife sharpening tool, specifically to a technology that facilitates the collection and subsequent washing and cleaning of knife sharpening debris. Background Technology
[0002] Sharpening tools are a very common household item. They are mainly used to sharpen dull blades to obtain a sufficiently sharp edge.
[0003] In everyday life, knife sharpening tools are very simple, usually just a simple whetstone or a stand built on top of that. However, in some situations where hygiene is a concern, the shavings produced when sharpening knives directly with a traditional whetstone will float and splash directly into the surrounding area. These tiny contaminants are not easily visible to the naked eye, and the problem of these shavings contaminating other kitchen utensils and other items persists.
[0004] Therefore, if the whetstone is hidden in an enclosed space during the sharpening process, the flying of shavings can be better avoided, thereby reducing the problem of pollution. Utility Model Content
[0005] Therefore, the technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a technology that facilitates the recycling and collection of grinding debris and subsequent water washing and cleaning.
[0006] To achieve the above objectives, this utility model provides a manual knife sharpener with a flip-top and a water tank, comprising a closed housing and a sharpening assembly;
[0007] The enclosed housing has a main shell and a flap, one end of which is hinged to the main shell. The flap has a sharpening opening. The main shell has a water groove recess.
[0008] The sharpening assembly is located inside the enclosed housing. The sharpening assembly has a support body, a rotating rod, and a sharpening blade. The support body is located in the recess of the water tank. The rotating rod is rotatably mounted on the support body. The sharpening blade is arranged on the rotating rod and is located below the sharpening opening.
[0009] Preferably, each set of the sharpening blade opening corresponds to two sets of sharpening blades below it, and the two sets of sharpening blades are clamped together for sharpening.
[0010] Preferably, one side of the main body shell has a curved handle for gripping.
[0011] The outer end of the curved handle has an auxiliary support point, and the two sides of the bottom of the main body shell are the main support points.
[0012] Preferably, the bottom sides of the flip cover have buckles, and the main body shell has openings that engage with the buckles.
[0013] Preferably, the sharpening opening is in multiple sets, and the sharpening blades arranged below the multiple sets of sharpening openings are made of different materials.
[0014] Preferably, the support has a first placement groove and a second placement groove, and the two ends of the rotating rod are mounted on the first placement groove and the second placement groove; when cleaning is required, the rotating rod and the grinding blade are removed from the first placement groove and the second placement groove.
[0015] Preferably, the enclosed housing also includes a locking structure, in which a flat grinding block is locked and placed.
[0016] The engaging structure has multiple sets of elastic rods arranged around the flat grinding block.
[0017] The beneficial effects of this utility model are as follows:
[0018] 1. A manual knife sharpener with a flip-top cover and a water tank is provided. The enclosed housing and water tank facilitate the collection and recycling of sharpening shavings, effectively preventing shavings from splashing and reducing pollution. After use, the water tank can be rinsed with water after flipping the cover, making it very convenient to use.
[0019] 2. The support body has a first placement slot and a second placement slot. When cleaning is required, the rotating rod and grinding blade can be removed from the first placement slot and the second placement slot, which makes operation convenient and internal cleaning easier.

[0029] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0030] First embodiment:
[0031] like Figures 1 to 4 As shown, this utility model provides a manual knife sharpener with a flip-top and a water tank, including a closed housing 10 and a sharpening assembly 20;
[0032] like Figure 1 As shown, the enclosed housing 10 has a main body shell 11 and a flip-top 12. One end of the flip-top 12 is hinged to the main body shell 11, and the flip-top 12 has a sharpening opening 121. The main body shell 11 has a water groove recess 111. The enclosed housing 10 prevents the splashing of shavings during sharpening, and the water groove recess 111 collects shavings and reduces contamination. When sharpening, the flip-top 12 is kept closed, and the blade is placed into the sharpening assembly 20 through the sharpening opening 121 for sharpening.
[0033] like Figure 2As shown, the sharpening assembly 20 is located inside the enclosed housing 10. The sharpening assembly 20 has a support body 21, a rotating rod 22, and a sharpening blade 23. The support body 21 is located in the recessed portion 111 of the water tank. The rotating rod 22 is rotatably mounted on the support body 21. The sharpening blade 23 is arranged on the rotating rod 22. The sharpening blade 23 is located below the sharpening opening 121. With this arrangement, the debris generated during sharpening is collected in the recessed portion 111 of the water tank.
[0034] Preferably, each set of the sharpening opening 121 corresponds to two sets of sharpening blades 23 below it, and the two sets of sharpening blades 23 are clamped together for sharpening.
[0035] Second embodiment:
[0036] like Figure 4 As shown, preferably, one side of the main body shell 11 has a curved handle 13 for holding, which makes sharpening the knife more stable when the hand holds the curved handle 13.
[0037] The outer end of the curved handle 13 has an auxiliary support point 131, and the two sides of the bottom of the main body shell 11 are the main support points 112. During sharpening, the bottom of the sharpener experiences significant force; the main support points 112 and the auxiliary support points 131 prevent friction at the bottom of the sharpener. Specifically, the main support points 112 are located at both the front and rear ends of the two sides of the bottom, thus forming a three-point support effect with the auxiliary support points 131, resulting in greater stability and smoothness.
[0038] like Figure 2 As shown, preferably, the bottom sides of the flip cover 12 have buckles 122, and the main body shell 11 has openings 113 that cooperate with the buckles 122.
[0039] Preferably, there are multiple sets of sharpening openings 121, and the sharpening blades 23 arranged below the multiple sets of sharpening openings 121 are made of different materials. When sharpening, different sharpening blades 23 of different materials are used for different knives.
[0040] Third embodiment:
[0041] like Figure 2 , 3 As shown, preferably, the support body 21 has a first placement groove 211 and a second placement groove 212, and the two ends of the rotating rod 22 are mounted on the first placement groove 211 and the second placement groove 212; when cleaning is required, the rotating rod 22 and the grinding blade 23 are removed from the first placement groove 211 and the second placement groove 212, which makes cleaning the inside of the grinding tool more convenient.
[0042] Preferably, the enclosed housing 10 further includes a locking structure 30, in which a flat grinding block 31 is locked and placed.
[0043] The engaging structure 30 has multiple sets of elastic rods 32 arranged around the flat surface grinding block 31. When it is necessary to disassemble the flat surface grinding block 31, simply pry the elastic rods 32 to remove the clamped flat surface grinding block 31. The flat surface grinding block 31 can be used for friction of other types of planar metal structures.
[0044] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
