Description

Technical Field

[0001] A non-stick cutter for kitchen knives of the present invention relates to a non-stick cutter that can prevent food ingredients from sticking to the kitchen knife when cutting vegetables, belonging to the field of kitchen utensils. In particular, it relates to a non-stick cutter that does not interfere with the smoothness of the cutting action when cutting vegetables with a kitchen knife and at the same time prevents food ingredients from sticking to the kitchen knife when cutting vegetables. Background Art

[0002] Currently, when cutting vegetables, especially when cutting ingredients such as potatoes, cucumbers or wax gourds, due to the large sliced area and certain moisture, it is always easy to stick to one side of the knife body and is not easy to fall off. As a result, the user has to use their hand to pick it off after cutting a few times, which is very troublesome and affects the normal cutting efficiency. In the prior art, a raised rib structure is added to one side of the kitchen knife body to prevent sticking during slicing. However, since the position of the rib on the kitchen knife is fixed, it affects the smoothness of the cutting surface of the kitchen knife, resulting in an increase in the friction between the kitchen knife and the food ingredient when the kitchen knife cuts in, and easily jamming the downward-cutting kitchen knife, affecting the smoothness of its cutting.

[0003] Publication No. CN2782332Y discloses an anti-stick knife, which belongs to a kitchen utensil, including a handle and a knife body. Its characteristics are that there is a horizontal convex anti-stick rib at a position 1.5 - 3 cm from the blade on the side of the knife body. This convex anti-stick rib affects the smoothness of the surface of the kitchen knife body and has an impact on the smoothness when the kitchen knife cuts in. When cutting relatively hard food ingredients, it is easy to jam the kitchen knife in the food ingredient and unable to cut deeper.

[0004] Publication No. CN210551366U discloses a non-stick knife structure, including: a stop bar, the stop bar is arranged outside the knife and is parallel to the blade; the stop bar includes: an adjustment structure; a first stop bar and a second stop bar, the first stop bar and the second stop bar are connected by the adjustment structure, and the adjustment structure is used to adjust the distance between the first stop bar and the second stop bar. The first stop bar is clamped on the side of the knife away from the handle, and the second stop bar is clamped on the side of the knife close to the handle. After this structure is clamped on the knife body, its position is fixed, causing protrusions on the surface of the kitchen knife and easily hindering the downward cutting when the kitchen knife cuts vegetables.

[0005] Publication No. CN208199352U discloses a portable electrode insulation barrel, which includes a barrel body, a barrel cover is provided on the barrel body. The barrel body includes an outer barrel and an inner barrel located inside the outer barrel. An electric heating wire is arranged between the inner barrel and the outer barrel, and there is a power supply device at the bottom of the outer barrel for supplying power to the electric heating wire. This device is relatively large in size and inconvenient for personnel to carry, and it needs to be flipped when taking the internal electrodes, making it inconvenient to use.

Detailed implementation manners

[0024] Embodiment 1

[0025] A non-stick knife device for a kitchen knife according to the present invention is realized as follows: A non-stick knife device for a kitchen knife according to the present invention is composed of a kitchen knife (1), a fixing device and a cleaning device. The fixing device is composed of a fixing clip (2), a connecting shaft (3), a rotating frame (4), a fixing ear (7), a limit cap (8) and a magnetic sheet (9). The fixing clip (2) is placed on the kitchen knife (1). The fixing clip (2) is located at one end of the kitchen knife (1). The fixing ear (7) is placed at the bottom of the fixing clip (2). The connecting shaft (3) is placed on the fixing ear (7) through the limit cap (8). A torsion spring (6) is built in the connecting shaft (3). One end of the rotating frame (4) is placed on the connecting shaft (3). The other end of the rotating frame (4) extends obliquely downward in the direction of the other end of the kitchen knife (1). A magnetic sheet (9) is placed between the fixing clip (2) and the kitchen knife (1). The cleaning device is composed of a cleaning strip (5) and a rubber sleeve (10). One end of the cleaning strip (5) is placed on the other end of the rotating frame (4). The other end of the cleaning strip (5) first extends to the other end of the kitchen knife (1), and then bends downward and extends to the outside of the kitchen knife (1) to form a bending part. The cleaning strip (5) is a steel strip. A rubber sleeve (10) is placed outside the cleaning strip (5);

[0026] In use, the fixing device is clamped on the blade of the kitchen knife (1) through the fixing clip (2), so that the cleaning bar (5) is slightly higher than the edge of the blade. When cutting vegetables, the bent part of the cleaning bar (5) first contacts the chopping board. As the kitchen knife (1) is pressed down, the bent part rotates against the spring stress of the torsion spring (6) at the connecting shaft (3), so as to avoid the cleaning bar (5) interfering with vegetable cutting. After the vegetable cutting is completed, when the kitchen knife (1) is lifted, the cleaning bar (5) returns to its original position under the reset action of the torsion spring (6) and pushes off the food ingredients adhering to the kitchen knife (1), so as to prevent the sliced food ingredients from adhering to the kitchen knife (1).

[0027] Embodiment 2

[0028] The difference between this embodiment and Embodiment 1 is that the other end of the cleaning bar (5) extends to the other end of the kitchen knife (1); in use, the cleaning bar (5) can be rotated and reset by the pushing force of the food ingredients, so as to avoid the situation that the cutting action is too fast, resulting in the reaction of the bent part of the cleaning bar (5) being too late, and the food ingredients attached to the other end of the kitchen knife (1) cannot be cleaned by the cleaning bar (5) in time.

[0029] Embodiment 3

[0030] The difference between this embodiment and Embodiment 1 is that the fixing device is composed of a spring (6), a connecting block (11), a fixing sleeve (12), a telescopic cylinder (13) and a sliding rod (14). The fixing sleeve (12) is sleeved on the handle of the kitchen knife (1). One end of the telescopic cylinder (13) is placed at the bottom of the fixing sleeve (12), and the other end of the telescopic cylinder (13) extends vertically towards the bottom of the kitchen knife (1). One end of the sliding rod (14) is slidably placed in the telescopic cylinder (13). A limiting ring is arranged in the telescopic cylinder (13), and the limiting ring corresponds to the sliding rod (14). The connecting block (11) is placed at the other end of the sliding rod (14). The spring (6) is sleeved on the sliding rod (14). One end of the spring (6) is placed at the mouth of the telescopic cylinder (13), and the other end of the spring (6) is connected to the connecting block (11). One end of the cleaning bar (5) is placed on the connecting block (11). The spring constant of the spring (6) is 50 N / m to 70 N / m; in use, the fixing device is fixed on the handle. When cutting vegetables, the cleaning bar (5) is pushed by the pushing force of the food ingredients to push the sliding rod (14) to slide in the telescopic cylinder (13) through the connecting block (11). At this time, the spring (6) is compressed. Then the kitchen knife (1) is lifted, the spring (6) is reset, and the connecting block (11) is pushed down, so as to push the cleaning bar (5) to push off the food ingredients adhering to the blade of the kitchen knife (1). Through the vertical telescopic structure, the cleaning area of the cleaning bar (5) is enlarged.

[0031] The cleaning strip (5) is designed as a steel strip, which can increase the rigidity of the cleaning strip (5). During use, since vegetables and other food ingredients contain a large amount of water, the vegetables have a large adhesion force. The steel strip of the cleaning strip (5) can extrude the food ingredients through its own rigidity, so that the food ingredients can be swept out of the blade surface of the kitchen knife (1), avoiding the situation that the cleaning strip (5) cannot sweep the food ingredients out of the blade surface of the kitchen knife (1) due to excessive adhesion force of the food ingredients squeezing the cleaning strip (5);

[0032] The design of having a rubber sleeve (10) outside the cleaning strip (5) can, on the one hand, increase the friction between the cleaning strip (5) and the food ingredients, making it easier to sweep the food ingredients. On the other hand, it can protect the steel strip. During use, the cleaning strip (5) inevitably comes into contact with water for a long time. Since the cleaning strip (5) is a steel strip, it is easy for the steel strip to rust. The rubber sleeve (10) outside the steel strip can prevent the rust of the steel strip from affecting the safety of the food ingredients;

[0033] The design of having a magnetic sheet (9) between the fixing clip (2) and the kitchen knife (1) can make the connection between the fixing clip (2) and the kitchen knife (1) tighter, preventing the fixing clip (2) from slipping off the kitchen knife (1);

[0034] The design of the spring constant of the spring (6) being 50 N / m to 70 N / m. During use, if the spring constant is too large, it is not convenient for the staff to perform quick and easy cutting actions, and it is not easy to make adaptive adjustments when cleaning the food ingredients. If the spring constant is too small, it cannot play a cleaning role when cleaning the food ingredients;

[0035] The design of the cleaning strip (5) cooperating with the torsion spring (6). During use, the cleaning strip (5) moves upward by overcoming the spring stress of the torsion spring (6), avoiding the cleaning strip (5) affecting the cutting action of the staff. When the staff lifts the kitchen knife (1), the torsion spring (6) resets, driving the cleaning strip (5) to move downward to clean the food ingredients adhering to the kitchen knife (1), thus preventing the food ingredients from adhering to the kitchen knife (1) and making it inconvenient for the staff to cut vegetables;

[0036] The design of the fixing clip (2) cooperating with the cleaning strip (5) can make the fixing clip (2) clamp the blade of the kitchen knife (1), so that the cleaning strip (5) is located above the blade. When cutting vegetables, the cleaning strip (5) can clean the food ingredients on the blade, preventing the food ingredients from adhering to the kitchen knife (1) in a fitting manner;

[0037] The design in which the cleaning bar (5), the connecting block (11) and the spring (6) cooperate. When in use, the staff uses the kitchen knife (1) to cut vegetables. When making a downward cutting motion, the ingredients adhere to the kitchen knife (1), pushing the cleaning bar (5) upward. As a result, the cleaning bar (5) drives the connecting block (11) to compress the spring (6), enabling the staff to perform rapid and continuous cutting actions without affecting the cutting operation. When the staff lifts the kitchen knife (1), the spring (6) resets, and through the connecting block (11), it pushes the cleaning bar (5) downward, so that the cleaning bar (5) pushes off the ingredients adhering to the kitchen knife (1).

[0038] The design in which the sliding rod (14), the connecting block (11) and the telescopic cylinder (13) cooperate can make the connecting block (11) correspondingly push the sliding rod (14) to move within the telescopic cylinder (13) when the spring (6) is compressed. When the spring (6) resets, the sliding rod (14) slides within the telescopic cylinder (13) to reset the connecting block (11). On the one hand, the telescopic cylinder (13) can guide and limit the sliding rod (14) to prevent the sliding rod (14) from deviating, thereby avoiding the cleaning bar (5) on the connecting block (11) from being offset by the resistance of the ingredients. On the other hand, the cooperation between the sliding rod (14) and the telescopic cylinder (13) forms a vertically telescopic structure, which can expand the cleaning area of the cleaning bar (5).

[0039] It achieves the purpose of not interfering with the smoothness of the cutting action of the kitchen knife (1) during cutting and at the same time preventing the ingredients from sticking to the kitchen knife (1) during cutting.

Any ordinary technician in the art, without departing from the scope of the present invention, can make some improvements. That is, all equivalent improvements made in accordance with the present invention should be covered by the scope of the present invention.

[0041] It should be further pointed out that when describing the above specific embodiments, for simplicity and clarity, only the differences from other embodiments are described. However, those skilled in the art should be aware that the above specific embodiments are also independent technical solutions in themselves.
