Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of zirconia ceramic knives, in particular to a zirconia ceramic knife. Background Art
[0002] Currently, most ceramic knives on the market are made of aluminum oxide or zirconium oxide, with zirconium oxide being more popular due to its excellent mechanical properties and chemical stability. These ceramic knives have advantages that traditional metal knives cannot match, such as being less likely to rust or become blunt, and not reacting with food. However, they also have certain limitations and room for improvement. Existing ceramic knives are usually made by dry pressing and then sintering at high temperatures. Although this production process can produce ceramic knives with a certain hardness, they are prone to cracking or breaking during actual use, especially when handling hard ingredients. Traditional ceramic knives are easily damaged when subjected to large impact forces due to the brittle nature of the material itself; in addition, the preparation cost is high and large-scale production is difficult. Utility Model Content
[0003] The purpose of the utility model is to provide a zirconia ceramic knife that can be folded and stored in order to solve the above-mentioned technical problems.
[0004] In view of this, the utility model provides a zirconia ceramic knife including a handle, the handle being provided with a storage groove; a hand guard, the hand guard being fixedly arranged on the other side of the handle away from the storage groove; a knife head, the knife head being movably arranged in the storage groove; and a blade, the blade being fixedly arranged on the knife head.
[0005] In this technical solution, when the zirconia ceramic knife is to be used, the knife head carrying the blade is extended from the storage slot. When the zirconia ceramic knife is not to be used, the knife head carrying the blade is returned to the storage slot, thus achieving the storage effect of the zirconia ceramic knife and better protecting the zirconia ceramic knife and the user.
[0006] In the above technical solution, further, a first plug is fixedly provided on the cutter head, the first plug is fixedly rotatably provided in a first circular groove, and the first circular groove is fixedly provided on the cutter handle.
[0007] In this technical solution, the cutter head is rotated in the first circular groove through the first insertion column, and the cutter head can achieve a rotational folding effect in the storage groove.
[0008] In the above technical solution, further, a mounting seat is fixedly provided on the side of the cutter head away from the first plug post, and a blade is fixedly provided on the mounting seat.
[0009] In this technical solution, the mounting seat fixes the position of the blade. Not only is the blade fixed on the cutter head, but the cutter head can also be removed, and the blade can be replaced in time, which greatly improves the efficiency of use.
[0010] In the above technical solution, further, a fixed opening is provided at the bottom of the storage slot, and the fixed opening is provided at the bottom of the storage slot corresponding to the position of the mounting seat.
[0011] In this technical solution, when the cutter head is folded and recovered, the blade and the mounting seat protrude, which may interfere with the storage slot during folding and recovery. A fixed opening is set corresponding to the storage slot. The fixed opening not only stores the mounting seat, but also fixes the recovered cutter head.
[0012] In the above technical solution, further, the blade is in a triangular shape.
[0013] In this technical solution, the cutting edge area of the blade is reduced, thereby reducing the risk of injury to the user during use; the blade is small in size, thereby reducing waste of resources.
[0014] In the above technical solution, further, it also includes a support plate, which is fixedly provided on the cutter head, and the tool handle is fixedly provided with a receiving arc groove corresponding to the support plate.
[0015] In this technical solution, the support plate provides a larger support area for the user when in use, saving effort during use, and the storage arc groove avoids mutual interference during overall storage after the support plate is set.
[0016] In the above technical solution, further, the hand guard is in the shape of an isosceles trapezoid, and a cavity is provided in the middle of the hand guard.
[0017] In this technical solution, the trapezoidal bottom of the hand guard extends to both sides, which increases the hand-holding area during use and improves the ease of use and labor-saving. The cavity setting avoids interference between the mounting seat, the blade and the hand guard. The hand guard and the cavity setting avoid harm to people when the blade is stored in the storage slot.
[0018] The beneficial effects of the utility model are:
[0019] 1. By setting the hand guard, the hand-holding area is increased during use, which makes the use more labor-saving and easy. The cavity setting avoids interference between the mounting base, blade and hand guard.

[0033] Example 1:
[0034] This embodiment provides a zirconia ceramic knife such as Figure 1As shown, the zirconia ceramic knife comprises a handle with a storage slot; a hand guard fixed to the other side of the handle away from the storage slot; a blade head movably mounted within the storage slot; and a blade fixed to the blade head. When the zirconia ceramic knife is ready for use, the blade is extended from the storage slot with the blade. When not in use, the blade head returns to the storage slot with the blade, effectively storing the zirconia ceramic knife. This provides better protection for the zirconia ceramic knife and the user.
[0035] like Figure 1 As shown, the blade head is fixedly provided with a first plug-in post, which is fixed and rotatable in a first circular groove, which is fixed on the blade handle. The blade head rotates in the first circular groove via the first plug-in post, and the blade head can achieve a rotational and foldable effect in the storage groove.
[0036] like Figure 1 As shown, a mounting base is fixedly provided on the side of the cutter head away from the first plug post, and a blade is fixedly provided on the mounting base. The mounting base fixes the blade in position, not only fixing the blade to the cutter head, but also allowing the cutter head to be removed, so that the blade can be replaced in time and the efficiency is greatly improved.
[0037] like Figure 1 As shown, a fixed opening is provided at the bottom of the storage slot, and the fixed opening is provided at the bottom of the storage slot corresponding to the position of the mounting seat. When the blade head is folded and recovered, the blade and the mounting seat protrude, which may interfere with the storage slot during folding and recovery. The fixed opening is provided in the storage slot to not only store the mounting seat but also fix the recovered blade head.
[0038] like Figure 1 As shown, the blade is triangular in shape, which reduces the blade's cutting area, reduces injuries to the user, and has a small blade size, which reduces resource waste.
[0039] like Figure 3 As shown, the tool also includes a support plate that is fixedly mounted on the tool head, and a circular arc groove is fixedly mounted on the tool handle corresponding to the support plate. When in use, the support plate provides a larger support area for the user, saving effort during use, and the circular arc groove prevents interference between the support plate and the tool when the tool is stored.
[0040] like Figure 4 As shown, the hand guard is shaped like an isosceles trapezoid, with a cavity in the middle. The bottom of the hand guard extends to both sides, increasing the grip area during use and improving ease of use. The cavity prevents interference between the mounting base, blade, and hand guard. The hand guard and cavity prevent injury when the blade is stored in the storage slot.
[0041] The embodiments of the present application are described above in conjunction with the accompanying drawings. Unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
