Description

Technical Field

[0001] This utility model relates to the field of juicer technology, and in particular to a screw head fixing structure for a juicer. Background Technology

[0002] Juicers, especially those using the screw extrusion principle, are widely popular because they effectively preserve the nutrients and flavor of fruits and vegetables. In existing technology, the stability of the screw head is crucial. Poor fixation can lead to shaking or displacement during high-speed rotation, reducing juice yield and juicing efficiency, as well as generating significant noise and negatively impacting the user experience. Simultaneously, after being processed by the cutting section, the ingredients need to smoothly enter the grinding section for extrusion. Commonly, poorly designed feed inlets can easily cause food accumulation, blockages, or poor feeding, especially when processing fibrous fruits and vegetables. Existing juicers still have room for improvement in these areas, such as anti-clogging designs at the feed inlet, optimized cutting blade layout, and enhanced stability of the screw head structure. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] In view of this, this application provides a juicer that allows fruit to fall smoothly into the screw head for pressing during the pressing process, preventing it from rising upwards, thus speeding up the juicing process. In addition, the gap between the upper blade and the fixed plate is relatively small, resulting in a large shearing force on the fruit, making it less likely to trap residue, and making it easy to clean.

[0005] This utility model also provides a swivel head fixing structure for a juicer. The upper and lower end faces of the fixing structure are parallel, and the side is an arc-shaped slope, which allows fruit residue or juice to slide along the arc-shaped slope, reducing the difficulty of cleaning.

[0006] (II) Technical Solution

[0007] This specification provides the following technical solution in its embodiments: a juicer, comprising a juicer body, wherein a cutting part, a fixing plate, and a grinding part are arranged sequentially from top to bottom inside the juicer body; the fixing plate includes a top end face and a bottom end face; the edge of the fixing plate is recessed inward, and the gap between the fixing plate and the inner wall of the juicer body forms a feeding port; an arc-shaped inclined surface is provided on the side of the feeding port near the fixing plate, and the arc-shaped inclined surface extends from the top end face of the fixing plate toward the grinding part; the top end face and the bottom end face of the fixing plate are parallel to each other.

[0008] In the above technical solution, the arc-shaped inclined surface is the arc surface of a semi-circular frustum. The arc-shaped inclined surface is inclined at 30° relative to the top end face, so that it can cooperate with the cutting part and the grinding part to form the cutting edge of the fixed plate, and allow fruit residue or juice to slide into the grinding part along the arc-shaped inclined surface. The upper end face and the lower end face of the fixed plate are flat. When the grinding part and the cutting part are working, the gap between the fixed plate and the upper and lower end faces is relatively small, the shearing force on the fruit is large, and it is not easy for residue to accumulate.

[0009] Furthermore, the grinding part includes a spiral head; the spiral head includes a first spiral protrusion disposed at the upper end and a second spiral protrusion disposed at the lower end; the outer periphery of the spiral head is also provided with a plurality of secondary spiral protrusions, the protrusion height and axial length of the secondary spiral protrusions are both smaller than the first spiral protrusion and the second spiral protrusion, and are distributed circumferentially along the outer wall of the spiral head.

[0010] In the above technical solution, setting the first spiral protrusion, the second spiral protrusion, and the sub-spiral protrusion can effectively improve the pressing efficiency.

[0011] Furthermore, the cutting part includes a blade connecting part; one side of the blade connecting part extends upward at an angle to form a first cutting edge, and the side of the blade connecting part away from the first cutting edge extends laterally along the upper end face of the fixing plate to form a second cutting edge.

[0012] In the above technical solution, the first cutting edge can quickly chop the fruit, and the second cutting edge, while slicing the fruit, pushes the residue remaining on the fixed plate into the grinding part.

[0013] Furthermore, the juicer body includes a feeding cup; the bottom outer wall of the feeding cup is provided with a pressing outer ring, and its bottom inner wall is provided with a pressing inner ring; the cup wall of the feeding cup extends downward beyond the pressing outer ring and the pressing inner ring to form a connecting end.

[0014] Furthermore, the juicer body includes a cup body; the top of the cup body extends outward to form an annular support portion; when the feeding cup is connected to the cup body, the inner wall of the annular support portion cooperates with the outer wall of the connecting end of the feeding cup, and the top end face of the annular support portion abuts against the pressing outer ring of the feeding cup.

[0015] Furthermore, when the feeding cup is connected to the cup body, the inner pressing ring of the feeding cup presses against the upper end face of the fixing plate.

[0016] In the above technical solution, the fixing plate is pressed down by the feeding cup and will not rotate during use, and it can prevent the fruit from jumping up due to the reaction force during the juicing process.

[0017] Furthermore, the grinding part also includes a grinding ring sleeved around the spiral head; the grinding ring is frustum-shaped, with its bottom cross-sectional area being smaller than its top cross-sectional area.

[0018] In the above technical solution, when the spiral head rotates, the grinding ring remains stationary. The first and second spiral protrusions of the spiral head squeeze larger pieces of pulp onto the grinding ring, and work with the grinding ring to press them into smaller pieces of pulp. Then, the smaller pieces of pulp are pressed into juice through the cooperation of the secondary spiral protrusions and the grinding ring.

[0019] Furthermore, the fixing plate is embedded in the top of the grinding ring, and the gap between the inwardly recessed parts on both sides of the fixing plate and the inner wall of the grinding ring constitutes the feed inlet.

[0020] In the above technical solution, the fruit can directly enter the grinding section through the feed inlet.

[0021] Furthermore, the cutting part, the fixing plate, and the grinding part are connected in sequence by a rotating shaft.

[0022] In the above technical solution, when the rotating shaft rotates, it will drive the spiral heads of the cutting and grinding parts to rotate, while the fixed plate remains stationary.

[0023] A auger head fixing structure for a juicer includes a fixing plate for matching and fixing with the auger head of the juicer. The fixing plate includes a top end face and a bottom end face. The edge of the fixing plate is recessed inward to form a recessed portion. The top end face and the bottom end face of the fixing plate are parallel to each other. The surface of the recessed portion is an arc-shaped slope.

[0024] In the above technical solution, the top and bottom faces of the fixing plate are parallel to each other and have a certain thickness, allowing the surface of the recessed portion to form an arc-shaped slope. Preferably, the shape of the arc-shaped slope can be a partial side of a frustum, and the arc-shaped slope is inclined at 30° relative to the top face, allowing fruit residue or juice to slide along the arc-shaped slope, reducing the difficulty of cleaning.

[0025] (III) Beneficial Effects

[0026] Compared with the prior art, the beneficial effects that at least one technical solution adopted in the embodiments of this specification can achieve include at least:

[0027] (1) By tightly fitting the top of the spiral head to the bottom end face of the fixing plate and optimizing the setting of the first, second spiral protrusions and the sub-spiral protrusion, the stability and axial force balance of the spiral head during rotation are significantly enhanced, effectively reducing shaking and improving the extrusion and grinding efficiency, thereby increasing the juice yield and machine life.

[0028] (2) The curved slopes on both sides of the fixed plate can effectively guide the cut food into the feed inlet smoothly, avoiding blockage. The optimized cutting part design enables more efficient initial crushing of food, creating favorable conditions for subsequent grinding.

[0029] (3) The feeding cup structure and the annular support part of the cup body are closely matched, which not only ensures that the feeding cup is firmly and sealed, but also presses the inner ring directly against the fixing plate, further locking the position of the fixing plate and the spiral head, and enhancing the overall stability of the core working parts.
