Description

Technical Field

[0001] The utility model relates to the technical field of juicers, in particular to a fruit cutting mechanism of a juicer. Background Art

[0002] Existing juicers, such as the juicing component of an extra-large-caliber juicer disclosed in Chinese patent publication No. CN220800741U on August 28, 2024, include a fruit cutting cup, a fruit cutting knife, a juicing cup, a juicing screw and a juicing mesh barrel. The top of the fruit cutting cup is open, the fruit cutting knife is arranged in the fruit cutting cup, the bottom of the juicing cup is connected to the bottom of the fruit cutting cup by a screw buckle, the bottom of the fruit cutting cup is provided with a drop port, the drop port connects the juicing mesh barrel and the juicing cup, the juicing screw is arranged in the juicing mesh barrel, the top of the juicing screw drives the fruit cutting knife to rotate, and the bottom of the juicing cup is fixedly connected to the base of the juicer. The juicing assembly of this new ultra-large-caliber juicer automatically cuts the fruit pulp into small pieces before it falls from the cutting cup into the juicing cup. The juicing screw then extracts the juice. However, the fruit cutter in the previous juicer tends to roll around inside the cup as it cuts the fruit, preventing the cutter from cutting quickly and resulting in low cutting efficiency. Therefore, the existing juicer's fruit cutting mechanism needs further improvement. Utility Model Content

[0003] The utility model aims to provide a fruit cutting mechanism of a juicer with high fruit cutting efficiency.

The top of the fruit cutting cup is provided with a feed inlet, the inner bottom surface of the fruit cutting cup is provided with a feed outlet, and the fruit cutting knife is vertically rotatable on the inner bottom surface of the fruit cutting cup. The fruit cutting knife includes a main 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 from top to bottom on the main body. The inner wall surface of the fruit cutting cup is provided with a fruit blocking protrusion, and the fruit blocking protrusion is provided with a first avoidance opening corresponding to the middle fruit cutting knife. The fruit blocking protrusion of the utility model can effectively block the movement of fruit flesh in the fruit cutting cup, preventing the fruit flesh from moving synchronously with the fruit cutting knife, thereby ensuring efficient cutting of the fruit flesh and improving the cutting efficiency of the fruit cutting knife.

[0006] The present invention can also be further improved as follows.

[0007] The middle fruit cutting knife is horizontally arranged on the main body.

[0008] The drop opening is arc-shaped, and a shrinking protrusion is provided in the middle of the drop opening. The shrinking protrusion divides the drop opening into a wide-mouth section and a narrow-mouth section. The width of the wide-mouth section is greater than that of the narrow-mouth section. Therefore, the narrow-mouth section can prevent some larger fruit pulp from falling until they are cut into smaller pulp and are allowed to fall from the wide-mouth section.

[0009] The inner wall surface of the fruit cutting cup is provided with a plurality of vertical fruit-blocking convex strips at annular intervals. The fruit-blocking convex strips can effectively block the movement of the fruit pulp in the fruit cutting cup, so that the fruit pulp can be cut efficiently.

[0010] The beneficial effects of the utility model are as follows:

[0011] The fruit-blocking protrusion of the utility model can effectively block the movement of the fruit pulp in the fruit cutting cup, and prevent the fruit pulp from moving synchronously with the fruit cutting knife, so that the fruit pulp can be cut efficiently, and the cutting efficiency of the fruit cutting knife is improved.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Example 1, as Figures 1 to 11As shown, a juicer includes a fruit cutting mechanism 19, a juice extraction cup mechanism 3 and a machine base 4. The fruit cutting mechanism 19, the juice extraction cup mechanism 3 and the machine base 4 are arranged in sequence from top to bottom. The fruit cutting mechanism 19 includes a fruit cutting cup 1 and a fruit cutting knife 2. The top of the fruit cutting cup 1 is provided with a feeding port, and the inner bottom surface 10 of the fruit cutting cup 1 is provided with a dropping port 14. The fruit cutting knife 2 is vertically rotated and arranged on the inner bottom surface 10 of the fruit cutting cup 1. The fruit cutting knife 2 includes a body 21, an upper spiral knife 22, a middle fruit cutting knife 23 and a lower fruit sweeping knife 24. The upper spiral knife 22, the middle fruit cutting knife 23 and the lower fruit sweeping knife 24 are distributed on the body 21 from top to bottom. The inner wall surface of the fruit cutting cup 1 is provided with a fruit blocking protrusion 11, and the fruit blocking protrusion 11 is provided with a first avoidance opening 13 corresponding to the middle fruit cutting knife 23. The juicer mechanism 3 and base 4 of the present invention are based on prior art. A motor 41 on the base 4 drives the juicing screw 31 of the juicer mechanism 3 to rotate. The top of the juicing screw 31 is in transmission connection with the fruit cutter 2, thereby driving the fruit cutter 2 to cut the fruit pulp. The fruit-blocking protrusion of the present invention effectively blocks the movement of the fruit pulp within the fruit cutter, preventing the fruit pulp from moving synchronously with the fruit cutter and being cut by the fruit cutter. This ensures efficient fruit cutting and improves the cutting efficiency of the fruit cutter.

[0025] As a more specific technical solution of the utility model.

[0026] The middle fruit cutter 23 is horizontally arranged on the main body 21 .

[0027] The blanking opening 14 is in an arc shape, and a shrinking protrusion 15 is provided in the middle of the blanking opening 14. The shrinking protrusion 15 narrows the width of the blanking opening 14. The shrinking protrusion 15 divides the blanking opening 14 into a wide-mouth section 17 and a narrow-mouth section 16. The width of the wide-mouth section is greater than that of the narrow-mouth section 16.

[0028] The inner wall surface of the fruit cutting cup 1 is provided with a plurality of vertical fruit blocking ridges 12 at annular intervals. The fruit blocking ridges can effectively block the movement of the fruit pulp in the fruit cutting cup, thereby enabling the fruit pulp to be cut efficiently.

[0029] The inner bottom surface 10 of the fruit cutting cup 1 is in a conical shape with a high center and low sides. The lower end of the lower fruit sweeping knife 24 extends downwardly and is close to the inner bottom surface 10 of the fruit cutting cup.

[0030] The inclination angle of the lower fruit sweeping knife 24 is adapted to the inclined angle of the inner bottom surface 10 of the fruit cutting cup, so that the lower fruit sweeping knife fits the fruit cutting cup better.

[0031] The outer end of the lower fruit sweeping knife 24 is provided with a fruit sweeping protrusion 25, which makes the fruit sweeping effect of the lower fruit sweeping knife better.

[0032] The inner bottom surface 10 of the fruit cutting cup 1 is provided with a plurality of annular grooves 18 from the inside to the outside. The annular grooves 18 are wedge-shaped. The plurality of annular grooves reduce the friction area between the fruit pulp and the inner bottom surface 10 of the fruit cutting cup, thereby achieving the purpose of reducing noise.
