AI Technical Summary
The fruit cutting mechanism of the existing juicer has a problem of flesh residue. The fruit cutting knife and the inner bottom surface of the fruit cutting cup do not fit, so the flesh cannot completely fall into the blanking mouth.
An improved fruit cutting mechanism is designed. The inner bottom surface of the fruit cutting cup is a conical inclined surface, equipped with a vertically rotating fruit cutting knife, including an upper spiral knife, a middle slicing knife and a lower slitting knife. The lower slitting knife extends inclinedly and closes to the inner bottom surface, and is equipped with fruit sweeping protrusions and annular grooves to improve the fruit sweeping effect, and prevent the movement of the pulp through the fruit sweeping bumps and fruit sweeping strips.
The residual-free sweeping effect of the pulp is achieved, which improves cutting efficiency and reduces noise, ensuring that the pulp enters the blanking port smoothly.

Description
Technical Field
[0001] The utility model relates to the technical field of juice extractors, and particularly relates to an improved fruit cutting mechanism for a juice extractor. Background Art
[0002] The existing juice extractor, such as a juice extraction assembly of a super-large caliber juice extractor disclosed in Chinese Patent Publication No. CN220800741U on August 28, 2024, includes a fruit cutting cup, a fruit cutting knife, a juice extraction cup, a juice extraction screw, and a juice extraction mesh cylinder. The top of the fruit cutting cup is open, the fruit cutting knife is arranged inside the fruit cutting cup, the bottom of the juice extraction cup is rotationally buckled with the bottom of the fruit cutting cup, a blanking port is arranged at the bottom of the fruit cutting cup, the blanking port communicates the juice extraction mesh cylinder with the juice extraction cup, the juice extraction screw is arranged inside the juice extraction mesh cylinder, the top of the juice extraction screw drives the fruit cutting knife to rotate, and the bottom of the juice extraction cup is fixedly connected with the machine base of the juice extractor. The juice extraction assembly of the super-large caliber juice extractor of the utility model can automatically cut the pulp into small pieces in advance. The pulp in the fruit cutting cup falls into the juice extraction cup from the blanking port, and then is juiced by the juice extraction screw. However, when the fruit cutting knife of the above juice extractor cuts fruits, since the inner bottom surface of the fruit cutting cup is flat and the fruit sweeping knife on the fruit cutting knife is horizontally arranged, there is a large gap between the fruit sweeping knife and the inner bottom surface of the fruit cutting cup, and the fruit sweeping knife does not fit the inner bottom surface of the fruit cutting cup, resulting in pulp remaining on the inner bottom surface of the fruit cutting cup and the pulp not being swept to the blanking port. Therefore, the fruit cutting mechanism of the existing juice extractor needs to be further improved. Content of the Utility Model
[0003] The purpose of the utility model is to provide a fruit cutting mechanism for a juice extractor with good fruit sweeping effect and no pulp residue.
[0004] The purpose of the utility model is achieved as follows:
[0005] An improved fruit cutting mechanism for a juice extractor includes a fruit cutting cup and a fruit cutting knife. The top of the fruit cutting cup is provided with a feeding port, the inner bottom surface of the fruit cutting cup is provided with a blanking port, the fruit cutting knife is vertically rotatably arranged on the inner bottom surface of the fruit cutting cup, the fruit cutting knife includes a body, an upper spiral knife, a middle fruit cutting knife, and a lower fruit sweeping knife. The upper spiral knife, the middle fruit cutting knife, and the lower fruit sweeping knife are distributed on the body from top to bottom. The inner bottom surface of the fruit cutting cup is in a conical shape with a high center and low surrounding. The lower end of the lower fruit sweeping knife extends downward obliquely, and the lower fruit sweeping knife is close to the inner bottom surface of the fruit cutting cup. Since the inner bottom surface of the fruit cutting cup of the utility model is a conical inclined surface, the cut pulp will automatically flow down from the center of the inner bottom surface of the fruit cutting cup to the surrounding of the inner bottom surface of the fruit cutting cup, and then be swept into the blanking port by the lower fruit sweeping knife. The pulp then falls into the juice extraction cup. Moreover, the lower fruit sweeping knife is very close to the inner bottom surface of the fruit cutting cup, and there is no pulp residue on the inner bottom surface of the fruit cutting cup. Therefore, the fruit sweeping effect of the utility model is good.
[0006] The utility model can also be further improved as follows.
[0007] The inclination angle of the downward fruit cutting knife is adapted to the inclined surface angle of the inner bottom surface of the fruit cutting cup, so that the downward fruit cutting knife fits the fruit cutting cup better.
[0008] The outer end of the downward fruit cutting knife is provided with a fruit sweeping protrusion, which makes the fruit sweeping effect of the downward fruit cutting knife better.
[0009] Multiple annular grooves are arranged on the inner bottom surface of the fruit cutting cup from the inside to the outside. The annular grooves are wedge-shaped. The structure of the multiple annular grooves reduces the friction area between the pulp and the inner bottom surface of the fruit cutting cup, so as to achieve the purpose of reducing noise.
[0010] The beneficial effects of the present utility model are as follows:
[0011] Since the inner bottom surface of the fruit cutting cup of the present utility model is a conical inclined surface, the cut pulp will automatically flow down from the center of the inner bottom surface of the fruit cutting cup to the periphery of the inner bottom surface of the fruit cutting cup, and then be swept into the blanking port by the downward fruit cutting knife. The pulp then drops into the juice extraction cup. Moreover, the downward fruit cutting knife is very close to the inner bottom surface of the fruit cutting cup, and there is no residual pulp on the inner bottom surface of the fruit cutting cup. Therefore, the fruit sweeping effect of the present utility model is good. Description of the Drawings
