[0032] In the related art, the existing juicer generally includes a screw assembly 500, a cup body assembly 400 and a filter assembly. The screw assembly 500 is rotatably accommodated in the cup body assembly 400, and the filter assembly is installed in the cup body assembly 400 and sleeved on the screw assembly 500. When juicing, the screw assembly 500 drives the food and the filter assembly to be squeezed, and the food cannot be crushed, resulting in low juicing efficiency of the juicer.

[0033] Reference Figures 1 to 4 According to the first aspect of the present invention, the filter assembly includes a mounting frame 100 and a filter element 200. The mounting frame 100 is provided with an avoidance channel 110. The side wall of the avoidance channel 110 is provided with an extrusion strip 130 and a plurality of through holes 120. The plurality of through holes 120 are arranged at intervals along the circumference of the avoidance channel 110. A plurality of extrusion protrusions 131 are arranged at intervals along the axial direction of the avoidance channel 110 on the side of the extrusion strip 130 facing the axis of the avoidance channel 110. The plurality of extrusion protrusions 131 are arranged at intervals along the axial direction of the avoidance channel 110. The extrusion protrusions 131 are used to squeeze and crush food. The filter element 200 is provided with a plurality of filter holes 210. The filter element 200 is arranged on the mounting frame 100, and the filter element 200 blocks the through holes 120. The filter holes 210 are connected to the corresponding through holes 120. In this way, the extrusion protrusions 131 can squeeze and crush food to improve the juicing efficiency of the juicer.

[0034] Specifically, the mounting frame 100 and the filter element 200 are both sleeve-shaped structures, and a plurality of through holes 120 are arranged at intervals along the circumference of the mounting frame 100. By providing a plurality of extrusion protrusions 131, when the screw assembly 500 of the juicer drives the food to be squeezed against the side wall of the avoidance channel 110, the extrusion protrusions 131 can squeeze and crush the food so that the food can be quickly squeezed by the screw body 510, and the juice can flow to the outside of the mounting frame 100 through the filter hole 210, which can improve the juicing efficiency of the juicer.

[0035] It is understandable that the filter element 200 is made of metal and the mounting frame 100 is made of plastic. When manufacturing the filter assembly, the filter element 200 can be placed on an injection mold first, and then the mounting frame 100 can be injection molded on the filter element 200. This can improve the connection stability between the filter element 200 and the mounting frame 100, which will not be described in detail here.

[0036] It should be noted that the filter element 200 may also be connected to the outer peripheral side of the mounting frame 100, and the filter element 200 may be mounted on the mounting frame 100 by welding or clamping, which will not be described in detail herein.

[0037] It should be pointed out that the edge of the extrusion protrusion 131 is sharp, so that the extrusion protrusion 131 can cut the food, so that the extrusion protrusion 131 can crush the food, which will not be described in detail here.

[0038] In some embodiments of the present invention, a reinforcing rib 140 is formed between two adjacent through holes 120 , and both ends of the reinforcing rib 140 are connected to the side walls of the avoidance channel 110 , which can improve the structural stability of the mounting frame 100 .

[0039] Specifically, the reinforcing rib 140 is extended in the up-down direction, one end of the reinforcing rib 140 extends upward to connect with the upper side of the periphery of the through hole 120, and the other end of the reinforcing rib 140 extends downward to connect with the lower side of the periphery of the through hole 120, which can increase the structural strength of the mounting frame 100, thereby improving the structural stability of the mounting frame 100.

[0040] In some embodiments of the utility model, an extrusion groove 132 is formed between two adjacent extrusion protrusions 131. The extrusion groove 132 penetrates the extrusion bar 130 along the circumference of the mounting frame 100, so that food can be squeezed by the end of the extrusion protrusion 131, and part of the food can enter the extrusion groove 132 to be squeezed and crushed by the side wall of the extrusion groove 132, thereby improving the juicing efficiency of the juicer.

[0041] Specifically, along the circumference of the mounting frame 100, the two ends of the extrusion groove 132 pass through the opposite sides of the extrusion bar 130 respectively. When the screw assembly 500 of the juicer drives the food to rotate, the food can collide with the end of the extrusion protrusion 131, so that part of the food can enter the extrusion groove 132. As the screw assembly 500 rotates, the food entering the extrusion groove 132 is squeezed and crushed by the side wall of the extrusion groove 132, which can improve the juicing efficiency of the juicer.

[0042] In some embodiments of the utility model, the mounting frame 100 includes a filter sleeve 101 and a mounting seat 102 connected to the filter sleeve 101, the mounting seat 102 is arranged at the bottom of the filter sleeve 101, the through hole 120 is arranged on the filter sleeve 101, and the mounting seat 102 is used to be clamped with the cup body assembly 400 of the juice extraction assembly.

[0043] In some embodiments of the present invention, the filter sleeve 101 and the mounting seat 102 are an integrated structure, which can reduce the number of molds, thereby reducing the production cost of the molds, and thus reducing the production cost of the juicer.

[0044] Specifically, the filter sleeve 101 and the mounting seat 102 can be integrally formed by injection molding, which can reduce the number of molds, thereby reducing the production cost of the molds, thereby reducing the production cost of the juicer.

[0045] In some embodiments of the present invention, a limiting structure is provided between the mounting frame 100 and the filter element 200, and the limiting structure is used to limit the rotation of the filter element 200, thereby increasing the service life of the filter assembly.

[0046] Specifically, when juicing, the food rotates along the circumference of the filter 200 in the avoidance channel 110. Due to the friction between the food and the filter 200, after long-term use, the filter 200 is easy to move relative to the mounting frame 100, causing damage to the filter assembly. By providing a limiting structure between the mounting frame 100 and the filter 200, the rotation of the filter 200 relative to the mounting frame 100 can be limited, thereby increasing the service life of the filter assembly.

[0047] In some embodiments of the present invention, the limiting structure includes a limiting groove 220 provided on the filter element 200 and a limiting protrusion 150 provided on the mounting frame 100. The limiting protrusion 150 is accommodated in the limiting groove 220 and can abut against the side wall of the limiting groove 220, so as to limit the rotation of the filter element 200 relative to the mounting frame 100, so as to increase the service life of the filter assembly.

[0048] Specifically, the limiting protrusion 150 is provided on the side wall of the avoidance channel 110, and the limiting groove 220 is provided on the upper end of the filter element 200. The limiting protrusion 150 is accommodated in the limiting groove 220 and can abut against the side wall of the limiting groove 220, so as to limit the rotation of the filter element 200 relative to the mounting frame 100, so as to improve the service life of the filter assembly.

[0049] It should be noted that the limiting structure can also be a structure in which a limiting hole and a limiting pin cooperate. The limiting hole is arranged on the filter element 200, and the limiting pin is arranged on the side wall of the avoidance channel 110, which can also limit the rotation of the filter element 200, which will not be described in detail here.

[0051] Specifically, when juicing, the power output end of the base assembly 300 drives the connecting shaft 520 to rotate, thereby driving the screw body 510 to rotate. By providing a plurality of extrusion protrusions 131, as the screw body 510 rotates, the food enters the guide channel 512, and the screw body 510 drives the food to collide with the extrusion bar 130. The extrusion protrusions 131 can squeeze and crush the food so that the food can be quickly squeezed by the screw body 510. The juice can flow to the outside of the mounting frame 100 through the filter hole 210, thereby improving the juicing efficiency of the juicer.

[0052] In some embodiments of the present invention, the minimum distance between the spiral portion 511 and the squeezing protrusion 131 is gradually reduced, so that the food can be gradually squeezed to facilitate juicing.

[0053] Specifically, from top to bottom, the diameter of the spiral portion 511 gradually increases, and the squeezing strip 130 is extended in the up and down directions, so that the minimum distance between the spiral portion 511 and the squeezing protrusion 131 gradually decreases. The spiral portion 511 can gradually push the food to abut against the mounting frame 100 and the filter element 200 to gradually squeeze the food, thereby facilitating juicing.

[0054] In some embodiments of the present invention, the extension direction of the extrusion protrusion 131 is inclined with respect to the axial direction of the avoidance channel 110, so that the food entering the extrusion groove 132 can be squeezed and collided with the side wall of the extrusion groove 132, and the food can be broken to improve the juicing efficiency of the juicer.

[0055] Specifically, the extrusion protrusion 131 is arranged to be inclined upward, and in the horizontal direction, the projection of the spiral portion 511 on the extrusion bar 130 is arranged to be cross-arranged with the extension direction of the extrusion protrusion 131, so that the spiral portion 511 can push the food entering the extrusion groove 132 to collide with the side wall of the extrusion groove 132, thereby crushing the food and improving the juicing efficiency of the juicer.
