Description

Technical Field

[0001] The present invention relates to an elliptical ceramic knife sharpening rod with a cushioning structure, and more particularly to a knife sharpening rod with a cushioning structure arranged in a hollow elliptical ceramic rod, which can increase the knife sharpening contact area, improve the use efficiency and absorb shock waves, thereby achieving the effect of protecting the ceramic rod; and the upper and lower pads of the cushioning structure simultaneously solve the problem that the hollow elliptical ceramic knife sharpening rod may be misaligned due to the user's bad usage habits. Background Art

[0002] Knives are indispensable tools in the kitchen. They are used every day for cooking. Whether it is a vegetable knife or a meat chopping knife, it will become blunt after long-term use. For example, fish or meat vendors in the market need to use knives to cut fish and meat every day, so the sharpness of the knives will affect the smoothness of their work. The more the knife is used, the lower its sharpness will be. Therefore, it is usually necessary to use a sharpening rod to make the blade sharper. In the early days, sharpening rods were made of metal such as stainless steel. Although the hardness of the sharpening rod is very high, for knives with steel blades, after several grindings, obvious dents will appear, and the knife cannot be effectively sharpened.

[0003] Therefore, there are improved ceramic knife sharpening rods 1 on the market, such as Taiwan Patent No. TWM310766 "Improved Structure of Ceramic Knife Sharpening Rod", please refer to Figure 1 As shown in FIG. 1 , it is a three-dimensional diagram of a conventional ceramic knife sharpening rod. The ceramic knife sharpening rod 1 has a handle 10, and a ceramic rod 11 is connected to the upper end. Since the ceramic rod 11 has a higher hardness than the conventional metal knife sharpening rod, the blade can be sharpened more sharply, which can improve the smoothness and convenience of work. It is obviously more practical than the traditional knife sharpening rod. However, the ceramic rod 11 of the ceramic knife sharpening rod 1 is a slender rod. When the knife is sharpened on the ceramic rod 11, the contact area between the two is limited, and the grinding efficiency is poor. Therefore, there is still a lot of room for improvement.

[0004] In addition, although some companies have already launched oval-shaped knife sharpening rods on the market to increase the contact area for sharpening, the rod bodies of these knife sharpening rods are mainly made of metal. If a ceramic knife sharpening rod is made into an oval shape, when it is hit, its oval shape will easily cause uneven stress dispersion and it will be very easy to break. Therefore, there are no oval-shaped ceramic knife sharpening rods on the market.

[0005] The inventor is a professional engaged in the manufacture and sale of knife sharpening rods and related products. He has long wanted to improve and overcome the inherent defect of oval ceramic knife sharpening rods that are easy to break. With many years of work experience, he has been thinking hard about ways to reform. Finally, after several experiments, corrections and improvements, the present invention was born. Summary of the invention

[0006] The conventional rod-shaped ceramic knife sharpening rod has a limited contact area with the knife and poor sharpening efficiency, while the oval-shaped ceramic knife sharpening rod is not resistant to collision and is prone to breakage. For the public, developing a ceramic knife sharpening rod with a larger sharpening contact area and not prone to breakage is a problem that the industry needs to solve.

Then, the sleeve head and the upper pad are fitted together, and the internal thread of the sleeve head is screwed and fixed with the thread section of the support rod protruding from the outside of the elliptical ceramic rod, and finally fixed with glue. The characteristic is that the hollow interior of the elliptical knife sharpening rod is provided with a buffer structure to absorb impact shock waves, buffer the impact force, and avoid the hollow ceramic rod inside from breaking; the ceramic knife sharpening rod is used to increase the contact area with the tool by virtue of the ceramic rod body with an elliptical periphery.

[0009] The elliptical ceramic knife sharpening rod with a buffering structure, wherein the elliptical flexible sleeve of the buffering structure is an elliptical sleeve with a diameter smaller than the hollow inner diameter of the elliptical ceramic rod.

[0010] The elliptical ceramic sharpening rod with a cushioning structure, wherein the lower pad and the upper pad of the cushioning structure are made of flexible materials so that the elliptical ceramic rod and the support rod are clamped and fixed; wherein the diameter of the protrusion of the lower pad is smaller than the hollow inner diameter of the elliptical ceramic rod, and is used to clamp and combine with the hollow bottom of the elliptical ceramic rod and cover its bottom upwards, so that the elliptical ceramic rod is fixed and can absorb impact waves.

[0011] The elliptical ceramic sharpening rod with a cushioning structure, wherein the lower pad and the upper pad of the cushioning structure are made of flexible materials so that the elliptical ceramic rod and the support rod are clamped and fixed; wherein the diameter of the protrusion of the upper pad is smaller than the hollow inner diameter of the elliptical ceramic rod, and is used to clamp and combine with the hollow upper part of the elliptical ceramic rod to fix the elliptical ceramic rod and absorb impact waves.

[0012] The oval ceramic knife sharpening rod with a cushioning structure has a lower pad and an upper pad of the cushioning structure respectively clamped on the bottom and the top of the oval hollow ceramic rod and fixed with glue, so that the oval ceramic knife sharpening rod will not rotate and dislocate.

[0013] After the assembly is completed, the present invention will not cause the oval ceramic rod to rotate due to the user's incorrect use, causing the relative positions of the oval ceramic rod and the handle to be misaligned, thereby reducing the sharpening efficiency; and the lower pad and the upper pad are made of soft materials, which are tightly combined with the oval ceramic rod. Once the sharpening rod accidentally falls to the ground and generates a shock wave, the lower pad and the upper pad can immediately absorb the shock wave, greatly reducing the possibility of the oval ceramic rod being broken and damaged.

[0014] During assembly, the lower pad of the cushioning structure and the elliptical flexible sleeve are sequentially inserted into the extension rod of the handle, and then the elliptical ceramic rod is inserted into the support rod so that the elliptical flexible sleeve is maintained in the hollow interior of the elliptical ceramic rod; then the bottom of the elliptical ceramic rod is engaged with the protrusion of the lower pad, and then the upper pad is placed into the top of the support rod so that its protrusion is engaged with the top of the elliptical ceramic rod, and then the sleeve is fitted with the upper pad, and the internal thread of the sleeve is screwed with the threaded section of the support rod protruding from the top of the elliptical ceramic rod, and then fixed with glue to complete the assembly.
