[0023] Reference Figure 1 And Figure 2 An embodiment of the utility model can include a main machine (not shown), a juicer cup 1 and a hopper 2.

[0024] The upper portion of the main machine is formed with a shape corresponding to the bottom of the juicer cup, so that the juicer cup 1 is installed on the main machine; the inside of the main machine is installed with a motor for generating driving force.

[0025] The juicer cup 1 is installed on the main machine, and one side of the juicer cup 1 is provided with a juice discharge port 101, and the other side is provided with a residue discharge port 102. The juicer cup 1 contains a screw rod 100, which is connected with the driving shaft of the motor and rotates in the juicer cup 1 under the driving of the motor to extrude the juicing material.

[0026] The hopper 2 can be combined with the upper portion of the juicer cup 1 through clamping, threaded connection and the like, for temporarily containing the juicing material and guiding it to the juicer cup 1.

[0027] Reference Figure 3 The side surface of the screw rod 100 is outwardly protruded to form a limiting portion 130, which separates the screw rod 100 from its axis direction into a cutting section 110 and a grinding section 120, the cutting section 110 mainly performs chopping of large juicing material, and the grinding section 120 performs extrusion of the chopped juicing material.

[0028] In the present application, the limiting portion 130 plays a supporting and limiting role on the screw rod 100 through cooperation with the juicer cup 1 and the hopper 2, which will be introduced below in combination with the juicer cup 1 and the hopper 2.

[0029] The juicer cup 1 is provided with a lower supporting portion, and when the screw rod 100 is arranged in the juicer cup 1, the lower supporting portion is supported on the lower end surface of the limiting portion 130; the bottom of the hopper 2 is provided with an upper supporting portion, and when the hopper 2 is combined with the upper portion of the juicer cup 1, the upper supporting portion abuts against the upper end surface of the limiting portion 130, that is, the limiting portion 130 is limited between the lower supporting portion and the upper supporting portion to play a supporting and limiting role on the screw rod 100.

[0030] The limiting portion 130 can be formed on the side surface of the screw rod 100 in various structures. In reference Figure 3In the embodiment, the limiting part 130 is a plurality of supporting pieces protruding from the side surface of the screw rod 100. It can be understood that the limiting part 130 can also be a supporting ring (not shown) protruding from the side surface of the screw rod 100, and the supporting ring is provided with a through channel penetrating from top to bottom, so that the juicing material enters the grinding section from the cutting section. It should be noted that the limiting part 130 is not limited to the supporting pieces and the supporting ring, and can also be other shapes, as long as it protrudes from the side surface of the screw rod 100 and is located between the juicing section 110 and the grinding section 120, and can support and limit the screw rod 100.

[0031] The limiting part 130 can be integrally formed with the screw rod 100, or can be fixedly connected to the side surface of the screw rod 100 by other means such as welding.

[0032] The limiting part 130 and the screw rod 100 can be made of the same material or different materials. Considering that the limiting part 130 needs to bear a large force during juicing, the limiting part 130 can be made of a high-strength metal material, such as stainless steel.

[0033] The lower supporting part can be formed in various structures in the juicing cup 1.

[0034] Reference Figure 4 and Figure 5 In an embodiment, a filter cylinder 140 for separating residue and juice is arranged in the juicing cup 1, and the filter cylinder 140 is prior art in the field and will not be described in detail here. The grinding section 120 of the screw rod 100 is accommodated in the filter cylinder 140, and the limiting part 130 is placed on the upper end surface of the filter cylinder 140, and at this time the filter cylinder 140 constitutes a lower supporting part for limiting the downward movement of the limiting part 130.

[0035] The inner side wall of the bottom of the hopper 2 extends downward to form a skirt 201, and the lower part of the skirt 201 has a shape corresponding to the upper part of the filter cylinder 140. When the hopper 2 is combined with the juicing cup 1, the lower part of the skirt 201 abuts against the upper end surface of the limiting part 130, and at this time the skirt 201 constitutes an upper supporting part for limiting the upward movement of the limiting part 130.

[0036] Continue to refer to Figure 3 The upper end surface of the filter cylinder 140 is also provided with an annular groove 1401, and the limiting part 130 is located in the annular groove 1401. The side surface of the annular groove 1401 and the side surface of the limiting part 130 cooperate to position the screw rod 100 in the radial direction, thereby reducing the shaking of the screw rod 100 during rotation.

[0037] The bottom of the skirt 201 extends to form a flange 2011, the height of the flange 2011 is substantially equal to the thickness of the limiting portion 130, when the hopper 2 is combined with the juicer cup 1, the flange 2011 is inserted into the annular groove 1401 and abuts against the bottom surface of the annular groove 1401. The arrangement of the flange 2011 can prevent the bottom of the skirt 201 from abutting too tightly against the upper end surface of the limiting portion and interfering with the rotation of the screw 100.

[0038] During the juicing process, the limiting portion 130 rotates with the screw 100 and can cause wear to the lower support portion and the upper support portion. Therefore, in some embodiments, the upper support portion and the lower support portion are also respectively provided with replaceable protective pads.

[0039] In some embodiments, the filtering structure of the juicer is arranged on the grinding section 120 of the screw 100, and the specific structure can refer to the patent document with publication number CN221533468U. It can be understood that for the juicer with such a structure, the lower support portion can be formed by an annular step formed on the inner side wall of the juicer cup 1 (not shown), the limiting portion 130 is rested on the annular step, and when the hopper 2 is combined with the juicer cup 1, the lower end surface of the hopper 2 abuts against the upper end surface of the limiting portion 130, at this time, the lower end surface of the hopper 2 constitutes the upper support portion.

[0040] In the present application, the limiting portion 130 serving as a fulcrum is arranged between the cutting section 110 and the grinding section 120, which shortens the distance from the cutting section 110 to the fulcrum, thereby reducing the moment generated by the eccentric force of the cutting section 110; in addition, the arrangement of the limiting portion 130 between the cutting section 110 and the grinding section 120 also decomposes the eccentric forces generated by the cutting section 110 and the grinding section 120 to the upper and lower sides of the limiting portion 130, the eccentric force generated by the lower grinding section 120 can offset part of the eccentric force generated by the upper cutting section 110, further reducing the moment acting on the limiting portion 130.

[0041] The above only describes preferred embodiments of the present application and is not intended to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement for part of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
