Description

Technical Field

[0001] This utility model relates to the field of juicers, specifically a cutting blade applied to the juicer barrel and the juicer barrel mechanism. Background Technology

[0002] Juicers are common household appliances, often used to extract juice from fresh fruits and vegetables to produce drinkable juice. Current juicers, for user convenience, feature a hopper that directly cuts the fruit or vegetable material, eliminating the need for users to chop it into appropriate sizes before juicing. The material can be placed directly into the hopper, where a cutting blade automatically cuts it, making it more convenient. However, because the material is not guided within the hopper, it is constantly pushed and struck by the cutting blade during the cutting process, causing it to move erratically and preventing it from being cut systematically. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a cutting blade for use in the juicer barrel and a juicer barrel mechanism.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A cutting blade for use in a juicer cylinder includes a blade shaft and a blade plate. The blade plate has a center line L on a plane of rotation. The blade shaft passes through the center line L, and the blade plate is divided into a first cutting edge and a second cutting edge on both sides of the blade shaft, with respect to the center line L. The second cutting edge includes a flat plate portion, a first bent portion, and a second bent portion. The first bent portion is connected to the side of the flat plate portion facing the direction of rotation, and the connection point with the flat plate portion has a first bending line. The first bent portion bends upward along the first bending line. The second bent portion is connected to the side of the first bent portion facing the direction of rotation, and the connection point with the first bent portion has a second bending line. The second bent portion bends along the second bending line. The first bending line and the side extension line of the second bent portion form a projection area g on the plane of rotation. The projection area g extends through the axis of the blade shaft.

[0006] The first bending line forms an angle α with the center line L.

[0007] The upward bending angle of the first bend is β, where 10° < β < 90°.

[0008] The second bend is provided with an auxiliary blade I facing the direction of rotation.

[0009] The second cutting blade also includes a third bend, which is located on the outer side of the first bend.

[0010] An auxiliary blade II is provided on the third bend facing the direction of rotation.

[0011] The flat plate portion of the second cutting blade is curved. The flat plate portion is first bent away from the direction of rotation, and then bent a second time towards the direction of rotation to form a V-shaped structure. The first and second bending portions are formed by bending the metal plate at the end of the flat plate portion in sequence.

[0012] A juicer's feed cylinder mechanism includes a feed cylinder, the top of which is a feed inlet, and the bottom of which is provided with a connection opening for connecting to the juicer's juicing cylinder. A blade holder is provided at the connection opening, and the aforementioned cutting blade is rotatably mounted on the blade holder.

[0013] The cutter shaft passes through the cutter holder and is connected at the bottom end to a coupling that drives the screw inside the juicing cylinder.

[0014] The beneficial effects of this utility model are as follows: One side of the cutting blade of this utility model is provided with a push plate structure formed by a first bending part and a second bending part. The projection area g formed on the plane of rotation between the first bending line of the first bending part and the side extension line of the second bending part passes through the axis of the blade shaft. That is, the space below the second bending part and in front of the side of the first bending part is directly connected to the cutting space where the entire first cutting edge is located. This not only allows the material to quickly cross the blade shaft and reach the first cutting edge for concentrated cutting after contacting the push plate structure, but also allows the material to be fully cut by the entire blade of the first cutting edge, thereby improving cutting efficiency. This cutting method can more easily cut larger pieces of material, enhance the adaptability of the juicer to materials, make the preparation of fruits and vegetables more flexible, and make it more convenient for users.

[0022] Reference Figures 1 to 7A juicer's feed cylinder mechanism includes a feed cylinder 1, the top of which is a feed inlet 11, and the bottom of the feed cylinder 1 is provided with a connection opening 12 that connects to the juicer's juicing cylinder, and a blade holder 13 for mounting a cutting blade is provided at the connection opening 12.

[0023] The cutting blade includes a blade shaft 2 and a blade plate 3. The blade shaft 2 passes through the blade holder 13 and is connected to a coupling at its bottom end, which is connected to the screw drive inside the juicing cylinder. The blade plate 3 has a center line L on the plane of rotation. The blade shaft 2 passes through the center line L, and the blade plate 3 is divided into a first cutting edge 31 and a second cutting edge 32 on both sides of the blade shaft 2 along the center line L. The first cutting edge 31 is a flat straight blade. The second cutting edge 32 includes a flat part 321, a first bent part 322, and a second bent part 323. The first bent part 322 is connected to the side of the flat part 321 facing the direction of rotation, and the connection between the first bent part 321 and the flat part 321 has a first bending line. The first bent part 322 bends upward along the first bending line. The second bent part 323 is connected to the side of the first bent part 322 facing the direction of rotation, and the connection between the second bent part 322 and the first bent part 323 has a second bending line. The line bends to a horizontal position, forming a push plate structure on the second cutting edge 32. The projection area g between the first bending line and the side extension line of the second bending part 323 is formed on the plane of rotation. The projection area g passes through the axis of the cutter shaft 2, that is, below the second bending part 323. The space in front of the side of the first bending part 322 is directly connected to the cutting space where the entire first cutting edge is located. This not only allows the material to quickly cross the axis of the cutter shaft 2 to reach the first cutting edge for concentrated cutting, but also allows the material to be fully cut by the entire blade of the first cutting edge, thereby improving cutting efficiency. This cutting method can more easily cut larger pieces of material, thereby enhancing the juicer's adaptability to a wider range of materials, making the selection of fruits and vegetables more flexible, and making it more convenient for users.

[0024] Furthermore, since the first bending line of the first bending part 322 has an angle α with the center line L of the blade plate 3, that is, the side of the first bending part 322 is inclined to form a guide surface, which can guide the material to move quickly toward the center. When the push plate structure contacts the material, the second bending part 323 hooks the material and pulls part of the material down. The material that is hooked down by the first bending part 322 moves toward the center and is concentrated at the first cutting edge for cutting, further improving the cutting efficiency.

[0025] As a preferred embodiment, the upward bending angle of the first bending portion 322 is β, where 10° < β < 90°, meaning the bending angle of the first bending portion 322 is an acute angle. With the guide surface facing downwards, it applies downward pressure to the material, facilitating its downward movement. Furthermore, the second bending portion 323 is provided with an auxiliary blade I 3231 facing the direction of rotation, which can more easily hook the material and cut it quickly. Even further, the second cutting blade 32 also includes a third bending portion 324, located on the outer side of the first bending portion 322. The third bending portion 324 catches the material hooked down by the second bending portion 323 and is quickly guided by the first bending portion 322 towards the center. Similarly, the third bending portion 324 is provided with an auxiliary blade II 3241 facing the direction of rotation, which can also cut the material.

[0026] Preferably, the flat plate portion 321 of the second cutting blade 32 is curved. The flat plate portion 321 is first bent away from the direction of rotation, and then bent a second time towards the direction of rotation to form a V-shaped structure. The first bending portion 322 and the second bending portion 323 are formed by bending the metal plate at the end of the flat plate portion 321 in sequence. The curved flat plate portion 321 provides strong support for the push plate structure formed by the first bending portion 322 and the second bending portion 323, so that the push plate structure can smoothly hook down and guide the material.
