[0002] A chopper is a very practical kitchen appliance that can quickly chop various ingredients, such as vegetables, meat, etc., saving time and energy of manual cutting.
[0003] A chopper rotates blades within a container, stirring and chopping the ingredients. However, the blades are fixed to a fixed position on a shaft, and their rotational trajectory is fixed. If the ingredients in the container are not in the blade's rotational trajectory, they will not be chopped. To chop all the ingredients, the rotating blades must stir the ingredients and throw them into the blade's rotational trajectory. This results in low chopping efficiency, and it takes a considerable amount of time to chop the ingredients into a paste for making baby food.
[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute prior art known to ordinary technicians in the field.

[0029] Example 1
[0030] Figure 1 Shows the exploded structure diagram of the shredder of the present invention. Figure 1The shredder includes a main assembly 1, a container 7, a first blade group 4 and a retaining ring 6. The main assembly 1 is arranged on the container 7. The first blade group 4 includes a knife shaft 41 and a first blade 42. The knife shaft 41 is connected to the main assembly 1, and the knife shaft 41 extends into the container 7. The first blade 42 is arranged on the knife shaft 41, and the first blade 42 is arranged in the container 7. The main assembly 1 drives the knife shaft 41 to rotate, thereby driving the first blade 42 on the knife shaft 41 to rotate in the container 7. Among them, the retaining ring 6 is sleeved on the knife shaft 41. The retaining ring 6 is arranged between the main assembly 1 and the first blade 42, and the retaining ring 6 is arranged in the container 7. When chopping food, the food is placed between the first blade 42 and the retaining ring 6. Then, during the operation of the shredder, the main assembly 1 drives the first blade 42 to rotate through the knife shaft 41, and the first blade 42 chops the food in the container 7. During the rotation of the first blade 42, as the volume of some of the food is reduced after being chopped, and as the shredder generates vibrations during operation, the retaining ring 6, in conjunction with the gravity, pushes the food downward, assisting the food in moving downward into the rotation path of the first blade 42. The retaining ring 6 assists the food in moving, thereby improving the shredder's shredding efficiency.
[0031] The distance between the first blade 42 and the bottom of the container 7 is ≥ 1 mm and ≤ 5 mm. Keeping the first blade 42 close to the bottom of the container 7 prevents large particles of food from accumulating at the bottom of the container 7 and being unable to be chopped by the first blade 42. Furthermore, limiting the minimum distance between the first blade 42 and the bottom of the container 7 prevents interference between the container 7 and the rotation path of the first blade 42.
[0032] Preferably, the outer diameter of the retaining ring 6 is curved to form a flange 61. When the retaining ring 6 is mounted on the blade shaft 41, the flange 61 is parallel to the sidewall of the container 7. The flange 61 increases the area of the retaining ring 6 close to the container 7, reducing the probability of large particles of food passing between the retaining ring 6 and the container 7, and ensuring that as much food as possible enters the rotation path of the first blade 42 for chopping.
[0033] More preferably, the distance between the flange 61 and the side wall of the container 7 is ≥1 mm, and the distance between the flange 61 and the side wall of the container 7 is ≤10 mm. While avoiding interference between the container 7 and the retaining ring 6, the retaining ring 6 is allowed to press the food to be chopped toward the first blade 42 as much as possible.
[0034] The blade shaft 41 is provided with a spline 411 and a shoulder 412. The spline 411 connects the blade shaft 41 to the main assembly 1, transmitting torque. The shoulder 412 is positioned between the first blade 42 and the retaining ring 6, limiting the position of the retaining ring 6 and preventing it from interfering with the rotational path of the first blade 42.
[0035] Preferably, the inner diameter of the retaining ring 6 is bent to provide a connecting tube 62, and the retaining ring 6 is sleeved on the cutter shaft 41 through the connecting tube 62. The connecting tube 62 improves the connection stability between the retaining ring 6 and the cutter shaft 41.
[0036] The container 7 is provided with an opening 71, and the cover of the fixing plate 2 is provided at the opening 71. The knife shaft 41 passes through the fixing plate 2. A sealing ring 3 is provided between the fixing plate 2 and the container 7 to ensure sealing performance.
[0037] The specific workflow of this utility model is as follows:
[0038] When chopping food, the food is placed under the retaining ring 6. After the shredder is started, the main unit assembly 1 drives the cutter shaft 41 to rotate, and the cutter shaft 41 drives the first blade 42 to rotate synchronously. The rotating first blade 42 stirs and chops the food in the shredder container 7. During the rotation of the first blade 42, some of the food is chopped and its volume is reduced. The vibration generated during the operation of the shredder, combined with the gravity of the retaining ring 6, causes the food above the first blade 42 to move toward the first blade 42 and enter the rotation path of the first blade 42. The shredder is not chopped until the retaining ring 6 is supported by the shaft shoulder 412 and the food is fully chopped by the first blade 42.
[0039] Example 2
[0040] Based on the first embodiment, the second embodiment discloses a shredder, which includes a second knife assembly 5, and the second knife assembly 5 includes a knife barrel 51 and a second blade 52. The knife barrel 51 is sleeved on the knife shaft 41. The retaining ring 6 is sleeved on the knife barrel 51. Among them, the knife barrel 51 can be key-connected to the knife shaft 41. The rotation of the knife shaft 41 drives the knife barrel 51 to rotate, and then drives the second blade 52 on the knife barrel 51 to rotate and chop food. The additional second blade 52 is provided to increase the number of blade rotation paths. Multiple blades chop food together, further improving the working efficiency of the shredder. At this time, the retaining ring 6 is sleeved on the knife barrel 51.
[0041] Preferably, the thickness of the blade of the second blade 52 is greater than the thickness of the blade of the first blade 42. A thicker blade can chop some hard objects, such as meat and bones.
[0042] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0043] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person of ordinary skill in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
