AI Technical Summary
Existing kitchen knives have smooth blades, making it easy for food to stick to the blade, which is inconvenient to use and difficult to clean.
It adopts an arc-shaped hollow design with elastic arc-shaped plates on both sides. When cutting, the arc-shaped plates deform and return to their original shape under the action of elasticity, automatically popping away the food that is stuck to them. The design of the arc-shaped plates and the blade body ensures a safe distance and smooth cutting.
It achieves automatic separation of food from the knife, improving ease of use and cleaning, while also enhancing finger safety and blade wear resistance.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cutting tools, and in particular to an arc-shaped anti-sticking knife. Background Technology
[0002] A kitchen knife mainly consists of a handle and a blade. Most existing kitchen knives have a smooth, flat blade surface. When using them, the object being cut tends to stick to the blade surface, making it inconvenient for users to use or clean, causing them trouble and inconvenience. Utility Model Content
[0003] The main objective of this invention is to provide an arc-shaped anti-stick knife, which aims to effectively solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the technical solution of this utility model is as follows:
[0005] This utility model discloses an arc-shaped anti-stick knife, comprising:
[0006] Handle;
[0007] An arc-shaped hollow blade body is connected to the blade handle. The arc-shaped hollow blade body has elastic arc-shaped plates on both sides. The two arc-shaped plates are convex outward and form a hollow cavity between them.
[0008] A blade body is disposed at the bottom of the arc-shaped hollow blade body, and the blade body has a cutting edge.
[0009] Compared with the prior art, the blade of this utility model adopts a hollow design and has outwardly protruding arc-shaped plates on both sides. When cutting vegetables, the two arc-shaped plates will deform slightly. After lifting the arc-shaped hollow blade to remove the blade from the table or food, the two arc-shaped plates will return to their original shape under the action of elasticity. This allows the food adhering to the arc-shaped plates to automatically bounce off and separate from the arc-shaped hollow blade, thus playing a role in preventing sticking.
[0010] In a preferred embodiment, the two arc-shaped plates are arranged symmetrically.
[0011] In a preferred embodiment, the upper part of the arc-shaped hollow cutter body is provided with a first planar transition portion.
[0012] In a preferred embodiment, the lower part of the arc-shaped hollow blade body is provided with a second planar transition portion; the upper part of the blade body is connected to the second planar transition portion.
[0013] In a preferred embodiment, the blade body is solid.
[0014] In a preferred embodiment, the two side surfaces of the blade are smoothly connected to the arc surfaces of the two arc-shaped plates.
[0015] To better understand and implement this invention, the following diagram, in conjunction with the accompanying drawings, provides a detailed description. Attached Figure Description

[0021] To better illustrate this utility model, a further detailed description of this utility model is provided below with reference to the accompanying drawings.
[0022] If the terms "first" or "second" are used in this document to define the components, those skilled in the art should know that the use of "first" or "second" is merely for the convenience of describing this utility model and simplifying the description, and unless otherwise stated, the above terms have no special meaning.
[0023] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.
[0024] In the following description, when referring to the accompanying drawings, the same numbers in different drawings denote the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.
[0025] See Figure 1 and Figure 2 This utility model discloses an arc-shaped anti-stick knife, comprising:
[0026] Handle 1;
[0027] The curved hollow blade body 2 is connected to the blade handle 1. The curved hollow blade body 2 has elastic curved plates 21 on both sides. The two curved plates 21 are convex outward and form a hollow cavity 22 between the two curved plates 21.
[0028] The blade body 3 is disposed at the bottom of the arc-shaped hollow blade body 2, and the blade body has a cutting edge.
[0029] Compared with existing technologies, the blade of this utility model adopts a hollow design and has outwardly protruding arc-shaped plates 21 on both sides. When cutting vegetables, the two arc-shaped plates 21 will deform slightly. After lifting the arc-shaped hollow blade 2 so that the blade 3 leaves the table or food, the two arc-shaped plates 21 will return to their original shape under the action of elasticity. This allows the food adhering to the arc-shaped plates 21 to automatically bounce off and separate from the arc-shaped hollow blade 2, thus preventing the food from sticking. In addition, the arc-shaped drop of the arc-shaped plates 21 can also help to hold back the fingers used to press the food, preventing the fingers from getting too close to the blade and cutting their fingers. This ensures that the fingers and the blade are at a safe distance, thus preventing hand cuts.
[0030] In one embodiment, the two arc-shaped plates 21 are symmetrically arranged, and the symmetrical convex arc-shaped plates 21, through the mirror-distributed double-sided arc surface design, make the force evenly distributed on both sides of the blade body during the cutting process.
[0031] In one embodiment, the upper part of the arc-shaped hollow cutter body 2 is provided with a first planar transition portion 23, which can increase the overall rigidity of the arc-shaped hollow cutter body 2 and prevent local deformation caused by the arc structure.
[0032] In one embodiment, the lower part of the arc-shaped hollow blade body 2 is provided with a second planar transition portion 24; the upper part of the blade body 3 is connected to the second planar transition portion 24, which can increase the overall rigidity of the arc-shaped hollow blade body 2 and prevent local deformation caused by the arc structure.
[0033] In one embodiment, the blade body 3 is solid, and the solid design improves the hardness and wear resistance of the blade and extends its service life.
[0034] In one embodiment, the two side surfaces of the blade body 3 are smoothly connected to the arc surfaces of the two arc plates 21, and the smooth transition eliminates the joint gap between the blade surface and the side plates, thereby enhancing the cutting smoothness.
[0035] This utility model is not limited to the above-described embodiments. If any modifications or variations to this utility model do not depart from the spirit and scope of this utility model, and if such modifications and variations fall within the scope of the claims and equivalent technologies of this utility model, then this utility model also intends to include such modifications and variations.
