Description

A portable paring knife

technical field

The invention relates to the field of daily necessities, in particular to a portable paring knife.

Background technique

In daily life, a paring knife is an extremely commonly used small kitchen appliance, mostly used for peeling fruits and vegetables. However, the peeling knives currently on the market often have reasons such as poor peeling effect, inconvenient portability, and high risk.

The Chinese patent No. CN90226015.4 discloses a dual-purpose melon and fruit peeler, which consists of a double-edged floating blade, a retractable knife, a plastic handle and a fixed knob, and a T-shaped front face of the plastic handle. slot, a telescopic knife is installed in the slot, two knife lugs with round holes protrude from the front side, and a cylindrical double-edged blade is floatingly installed. Although this patent utilizes the double-edged knife for peeling, the retractable knife for cutting and speckle removal, which realizes the integration of cutting and peeling, but it is very unsafe to expose the double-edged knife to the outside. Long is not conducive to storage.

The Chinese patent with the patent number CN201720521501.3 discloses a retractable fruit knife, which includes a knife body, a sleeve, a blade base, a rotating handle and a screw rod. The knife body is detachably mounted on the blade base. The cutter body can move along the length direction of the sleeve; the screw rod is connected with the blade base; the rotating knife handle is installed on one end of the screw rod and is located at the bottom of the sleeve; When the handle is rotated, the screw rod can drive the blade base to move along the length direction of the sleeve. Although the patented knife body integrates serrated edge, peeling blade, and cutting blade, and the screw rod realizes the expansion and contraction of the knife body, the plate structure of the knife body is not conducive to peeling and spot removal, and the screw rod slows down the expansion and contraction speed of the knife body , and the overall structure becomes complicated, which is not conducive to use and maintenance.

Contents of the invention

The technical problem to be solved by the present invention is to provide a portable peeling knife with good peeling effect, easy to remove spots, safe and convenient, and easy to store in view of the problems in the background technology.

The technical solution of the present invention to solve the above-mentioned problems is: a portable paring knife, which is composed of a knife body and a handle. The knife tip, the middle part of the knife body is provided with a peeling blade along the center line, and the rear end of the knife body is provided with a push handle. The knife handle is composed of a cylindrical handle body and a handle cover covering the rear end of the handle body. There is a cavity that can accommodate the knife body. The cavity extends from the rear end of the handle body to the front end. The handle body wall outside the cavity is provided with a vertical seam that can accommodate the sliding of the push handle. The vertical seam extends from the rear end of the handle body to the front end. But not through the front end.

Further, the handle body is a solid structure, and the cavity is a gap that can accommodate the semi-cylindrical cutter body to pass through the front and rear ends of the handle body. Specifically, the handle body can adopt a solid structure made of solid wood or PVC.

Further, the handle body is a hollow structure, an arc-shaped interlayer wall is arranged on the inner wall of the handle, and the cavity is formed between the interlayer wall and the handle body wall. Specifically, the handle body can be a hollow structure made of aluminum alloy profiles, and the front end of the handle body can also be provided with a sealing plate integrated with the interlayer wall.

Further, an arc portion is provided on the side of the knife body opposite to the peeling blade, and the arc portion is coaxial with the knife body.

Further, a scraper or a brush is provided on the cavity opening at the front end of the handle.

Further, the rear end of the handle body is provided with external threads, the inner wall of the handle cover is provided with internal threads matching the external threads at the rear end of the handle body, and the handle cover and the handle body are installed through threaded connection.

Further, the knife body and the push handle are detachably connected, the rear end of the knife handle is provided with a round hole, and the push handle is an "I"-shaped structure composed of an upper plate, a vertical plate, and a bottom plate. The front end of the bottom plate has an extension section, and the extension end An upward boss is arranged on the top, and the cutter body is installed on the boss of the push handle through a round hole.

The beneficial effects of the present invention are as follows: 1. The peeling is neat and convenient for spot removal. The knife body of the present invention has a semi-cylindrical structure instead of a traditional plate structure. When peeling with the peeling blade, it will not cut off the fruit or vegetable, nor will it damage the pulp or vegetable too deeply. The thin outer layer of a fruit or vegetable; when spotting or gouging out rotten areas, simply insert the point of the knife and turn gently to easily gouge out the pits or rotten areas. Therefore, no matter peeling or spot removal, it is effective and convenient.

2. Safe to use and convenient to store. In the present invention, only the peeling blade has a blade, but the peeling blade is located in the middle of the knife body, which is not easy to hurt people, but the tip of the knife may pierce people, but the tip of the knife is not sharpened, and the knife body can be retracted into the handle after use. Small size, easy to carry. Therefore, compared with traditional peeling knives, the present invention is safer and more convenient to store and carry.

3. Parts can be disassembled for easy cleaning and maintenance. When the present invention is assembled, it is only necessary to insert the knife body from the rear end of the handle body, insert the push handle into the vertical seam on the handle body wall outside the cavity, and install the handle cover, which is very convenient for disassembly and assembly, and is beneficial for cleaning and maintenance. Furthermore, the push handle and the cutter body can also be connected in a detachable manner, which can further reduce the processing difficulty of the cutter body.

4. Control the curling direction of the peel or vegetable peel to prevent it from falling on the user's arm or clothes. On the knife body of the present invention, the side opposite to the peeling blade is provided with an arc portion, and the arc portion is coaxial with the knife body, so that the middle and rear portion of the knife body is not semi-cylindrical, and the arc angle of the knife body section is greater than 180°, when the peeling blade is peeling, the peel of the fruit or vegetable can be curled toward the forward direction of the peeling blade, so as to prevent the peel of the fruit or vegetable from falling on the user's arm or clothes.

5. When retracting the cutter body, clean the surface of the cutter body. In the present invention, a scraper or a brush is arranged on the cavity opening at the front end of the handle body. When the knife body is stretched out or retracted, the brush or scraper can clean the peels, vegetable peels, soil and water stains attached to the knife body. Wait, keep the knife body clean.

To sum up, the present invention peels neatly, is practical and safe, is easy to disassemble, facilitates storage, is suitable for carrying out, and has a very good prospect of use.
