[0022] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail below with reference to the accompanying drawings.

[0023] In the description of the present invention, it should be noted that the terms "center", "middle", "upper", "lower", "left", "right", "inside", "outside", "top", "bottom", "side", "vertical", "horizontal", "first", "second", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] Example 1

[0026] refer to Figure 1 and Figure 2 A juice extraction assembly comprises a screw 1 driven by a motor and a filter cover 2 connected to the bottom of the screw 1 and rotating with the screw 1, wherein the outer surface of the screw 1 is provided with a plurality of spiral cutting blades 101, and the filter cover 2 is provided with a plurality of spiral ribs 201, wherein the spiral ribs 201 extend spirally from the connection between the spiral cutting blades 101 and the inner wall of the filter cover 2 along the inner wall of the filter cover 2, and two adjacent spiral cutting blades 101 and the outer wall of the screw 1 form an outer spiral groove 102, and two adjacent spiral ribs 201 and the outer wall of the screw 1 form an outer spiral groove 102. The inner wall of the filter cover 2 forms an inner spiral groove 202, and the inner spiral groove 202 is provided with a juice discharge channel passing through the side wall of the filter cover 2. The transition from the outer spiral groove 102 to the inner spiral groove 202 forms an inner spiral groove entrance 203. A protrusion 3 is provided on the inner wall of the filter cover 2 at the inner spiral groove entrance 203. When larger materials enter from the inner spiral groove entrance 203, the protrusion 3 can cut them, making the materials entering the inner spiral groove 202 smaller, thereby improving their passability and reducing the probability of slag jamming.

[0027] Figure 3A schematic diagram of the structure of the protrusion 3 is shown. A sharp portion 301 is provided at one end of the protrusion 3 facing the material. When a large piece of material passes through the protrusion 3, the sharp portion 301 can cut the material more easily.

[0028] The protrusion 3 includes a first guide surface 302 and a second guide surface 303. The first guide surface 302 is an inclined surface extending from the sharp portion to the direction of the lower spiral rib 201 of the inner spiral groove 202, and the second guide surface 303 is an inclined surface extending from the sharp portion 301 to the direction of the upper spiral rib 201 of the inner spiral groove 202. After being cut by the sharp portion 301, the large piece of material continues to move into the spiral groove 202. The inclined first guide surface 302 and the lower spiral rib 201 of the inner spiral groove, as well as the inclined second guide surface 303 and the upper spiral rib 201 of the inner spiral groove 202 can squeeze the cut material, thereby reducing the width of the material and preventing it from being stuck between the two spiral ribs 201 after entering the spiral groove 202.

[0029] The minimum distance between the first guide surface 302 and the spiral rib 201 at the lower end of the inner spiral groove 202 is D, and the minimum distance between the second guide surface 303 and the spiral rib 201 at the upper end of the inner spiral groove 202 is d. D and d are smaller than the width inside the inner spiral groove 202, so that the width of the material after being cut and extruded by the protrusion 3 is smaller than the width inside the inner spiral groove 202, further reducing the probability of slag jamming.

[0030] Example 2

[0031] Figure 4 Another structure of the protrusion 3 in the present application is shown, which differs from Example 1 in that, in Example 2, the first guide surface 302 is an arcuate surface extending from the sharp portion 301 toward the lower end spiral rib 201 of the inner spiral groove 202, and the second guide surface 303 is also an arcuate surface extending from the sharp portion 301 toward the upper end spiral rib 202 of the inner spiral groove 202.

[0032] Example 3

[0033] Figure 5 Another structure of the protrusion 3 in the present application is shown, which differs from Example 1 in that, in Example 3, the first guide surface 302 is a vertical surface extending from the sharp portion 301 toward the lower end spiral rib 201 of the inner spiral groove 202, and the second guide surface 303 is a horizontal surface extending from the sharp portion 301 toward the upper end spiral rib 201 of the inner spiral groove 202.

[0034] It can be understood that the first guide surface 302 can also be a multi-section inclined surface or a multi-section arc surface; the second guide surface 303 can also be a multi-section inclined surface or a multi-section arc surface. The first guide surface 302 can also be any combination of the above-mentioned one-section inclined surface, one-section arc surface, multiple sections of inclined surfaces, and multiple sections of arc surfaces; the second guide surface 303 can also be any combination of the above-mentioned one-section inclined surface, one-section arc surface, multiple sections of inclined surfaces, and multiple sections of arc surfaces.

[0035] It should be noted that the protrusion 3 can be set not only on the inner wall of the filter cover 2, but also on the outer wall of the screw 1 at the inner spiral groove inlet 203, as long as it can cut the bulk material entering the inner spiral groove 202.

[0036] It is understandable that a plurality of protrusions 3 may be provided at the inlet 203 of the inner spiral groove, so as to cut large pieces of material into smaller pieces.

[0037] Example 4

[0038] like Figure 6 As shown, the present application also provides a juicer, including a base (not shown) provided with a driving motor, a juice collecting cup 4 installed on the top of the base, the above-mentioned juice squeezing assembly detachably arranged in the juice collecting cup 4, and a drop cup 5 covering the juice collecting cup 4; the screw 1 of the juice squeezing assembly is connected to the driving motor in a driving manner, a fixed extrusion sleeve 401 is arranged in the juice collecting cup 4, an extrusion gap is formed between the filter cover 2 and the fixed extrusion sleeve 401, and a feed port is arranged on the drop cup 5. When squeezing juice, the material enters the drop cup 5 from the feed port, and is initially crushed under the action of the spiral cutting blade 101 of the screw 1 and the inner wall of the drop cup 5. When the material moves to the entrance 203 of the inner spiral groove, the large pieces of material are further cut by the protrusion 3, so that the material entering the inner spiral groove 202 becomes smaller, so that it can smoothly pass through the inner spiral groove 202, avoiding residue jamming, and improving the user experience.
