Description

Technical Field

[0001] This application relates to the field of cutting tool technology, and in particular to a bayonet blade disc. Background Technology

[0002] Coffee is a beverage made from roasted and ground coffee beans. As one of the world's three major beverages, it, along with cocoa and tea, is a popular drink worldwide. The coffee tree is a perennial evergreen shrub or small tree belonging to the Rubiaceae family. The coffee we drink daily is made from coffee beans using various brewing methods. Coffee beans refer to the kernels inside the fruit of the coffee tree, which are then roasted using appropriate methods. With the improvement of people's living standards, coffee has become increasingly popular among consumers, and drinking coffee has become a fashionable lifestyle. Especially for coffee lovers, a cup of fragrant and delicious coffee can greatly improve their work efficiency. Many coffee lovers prefer to grind their own coffee using a coffee machine, and the burr in the coffee machine is a crucial component that affects the quality of the ground coffee.

[0003] In the existing technology, the arrow-shaped blade disc is not convenient for quickly and evenly grinding coffee beans during use, resulting in low grinding efficiency. To address this issue, we propose an arrow-shaped blade disc. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the arrow-shaped blade disc is not convenient for quickly and evenly grinding coffee beans, resulting in low grinding efficiency. The proposed arrow-shaped blade disc is a solution to this problem.

[0005] The arrow bayonet disc provided in this application adopts the following technical solution: The arrow-shaped blade disc includes an outer blade and an inner blade. The outer side of the inner blade has multiple transverse teeth along its circumference for cutting coffee beans. The outer blade has a groove on the side away from the inner blade. The inner wall of the groove has multiple coarse, dense, prismatic conical teeth. The inner blade is connected to a spiral coarse tooth, and a gear is provided on the spiral coarse tooth.

[0006] Furthermore, the inner blade and the helical coarse teeth are provided with coaxially arranged through holes.

[0007] Furthermore, two symmetrical air grooves are provided on the outer side of the outer blade, and both air grooves communicate with the groove.

[0008] Furthermore, the diameter of the outer blade is larger than the diameter of the inner blade, and the thickness of the outer blade is greater than the thickness of the upper inner blade.

[0009] Furthermore, both the outer and inner blades have two threaded holes, and a fixing bolt is connected to the threaded hole.

[0010] In summary, this application includes at least one of the following beneficial technical effects: 1. This solution uses horizontal teeth to cut coffee beans horizontally, resulting in more even grinding, saving time, producing a more uniform and fine powder texture, and rotating at a faster speed. 2. This solution uses gears to grind coffee beans more finely and evenly, and also increases the grinding speed.

[0011] This invention enables rapid and uniform grinding of coffee beans during use, effectively improving grinding efficiency. It has a simple structure and is easy to use. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0015] Reference Figures 1-4 The arrow-shaped cutting disc includes an outer blade 1 and an inner blade 2. The outer blade 2 has multiple transverse teeth 5 along its circumference, which are used to cut coffee beans horizontally. The outer blade 1 has a groove on the side away from the inner blade 2. The inner wall of the groove has multiple coarse and dense prismatic conical teeth 8. The inner blade 2 is connected to a spiral coarse tooth 6, which is equipped with a gear 7. The inner blade 2 and the spiral coarse tooth 6 have coaxially arranged through holes 4. The diameter of the outer blade 1 is larger than the diameter of the inner blade 2, and the thickness of the outer blade 1 is larger than the thickness of the inner blade 2. Both the outer blade 1 and the inner blade 2 have two threaded holes 3, and the threaded holes 3 are internally threaded with fixing bolts.

[0016] In this embodiment, two symmetrical air grooves 9 are provided on the outer side of the outer blade 1. Both air grooves 9 are connected to the groove. The air grooves 9 are used to connect the quick-connect connector of the air pump, so that the residual powder in the outer blade 1 and the inner blade 2 can be quickly removed by the air pump.

[0017] The implementation principle of the arrow-shaped blade disc in this application embodiment is as follows: During use, a crank is inserted into the through hole 4. Since the through hole 4 is an irregular cylindrical structure, it can drive the entire blade disc to rotate and grind. The horizontal teeth 5 on the inner blade 2 and the spiral coarse teeth 8 on the outer blade 1 are used to coarsely grind the coffee. The horizontal teeth 5 can cut the coffee beans horizontally, making the beans more evenly ground, saving time, and producing a more uniform and delicate powder texture. The rotation speed is faster. At the same time, through the setting of gear 7, the coffee beans can be ground more finely and evenly, and the grinding speed is increased. The coffee enters the coarse and dense prismatic conical teeth 6 for secondary fine grinding. Due to the different teeth on the blade disc, the combination of concave and convex shapes makes the powder output smoother and the residual powder less. Moreover, it ensures that the coffee is ground more evenly during grinding, and it is also more labor-saving. At the same time, through the setting of two air grooves 9, the two air grooves 9 are connected to the air pump through a quick-connect connector. The air pump can quickly remove the residual powder in the outer blade 1 and the inner blade 2.

[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
