The base has an output end. The cup body assembly 100 is arranged on the base. The cup body assembly 100 is provided with a juice extraction chamber 110 and a feed channel 120. The feed channel 120 is communicated with the juice extraction chamber 110. The juice extraction assembly 200 comprises a juice extraction member 210 and a first connecting shaft 220 connected to the juice extraction member 210. One end of the first connecting shaft 220 is connected to the output end. The juice extraction member 210 is rotatably accommodated in the juice extraction chamber 110. The axis of the feed channel 120 is offset along the axis of the juice extraction member 210. The juice extraction member 210 is provided with The extruding portion 211 is arranged in a spiral shape, and the pre-cutting component 300 includes a pre-cutting piece 310 and a second connecting shaft 320 connected to the pre-cutting piece 310.

The pre-cutting piece 310 is provided with a cutting portion 311 arranged in a spiral shape. A notch 201 is formed between the lower end of the cutting portion 311 and the upper end of the extruding portion 211. In this way, by providing the notch 201, the food cut by the cutting portion 311 can fall onto the extruding portion 211 under the action of its own gravity, which can increase the feeding speed of the food, thereby improving the juicing efficiency of the juicer.

[0033] Specifically, the lower end of the cutting portion 311 is not connected to the upper end of the squeezing portion 211, and the lower end of the cutting portion 311 and the upper end of the squeezing portion 211 are spaced apart along the circumference of the juicing assembly 200. When juicing, the output end of the machine base drives the second connecting shaft 320 to rotate through the first connecting shaft 220, so that the juicing piece 210 and the pre-cutting piece 310 rotate, and the food enters the juicing chamber 110 through the feeding channel 120. The food is first cut by the cutting portion 311, and the cut food moves downward in a spiral as the pre-cutting piece 310 rotates. When the food moves to the top of the notch 201, the food can fall onto the squeezing portion 211 under the action of its own gravity, so that the food can be squeezed by the squeezing portion 211, which can increase the feeding speed of the food, thereby improving the juicing efficiency of the juicer.

[0034] It should be noted that the cup body assembly 100 is connected to a juice outlet pipe 103 and a residue discharge pipe 104. The juice outlet pipe 103 is provided with a juice outlet channel, and the residue discharge pipe 104 is provided with a residue discharge channel.

[0035] It should be pointed out that the base includes a shell and a driving motor arranged in the shell, and the output end is arranged on the output shaft of the driving motor, which will not be described in detail here.

[0036] In some embodiments of the present invention, a transmission structure is provided between the first connecting shaft 220 and the second connecting shaft 320. The first connecting shaft 220 drives the second connecting shaft 320 to rotate through the transmission structure, which can facilitate the synchronous rotation of the juice extraction component 210 and the pre-cut component 310 so that the width of the notch 201 remains constant.

[0037] Reference Figure 3 In some embodiments of the utility model, the transmission structure includes a transmission part 221 provided on the first connecting shaft 220 and a transmission groove 321 provided on the second connecting shaft 320.

The transmission part 221 abuts against the side wall of the transmission groove 321, so that the first connecting shaft 220 can drive the second connecting shaft 320 to rotate, which can facilitate the synchronous rotation of the juice extraction part 210 and the pre-cut part 310, so that the width of the notch 201 remains constant.

[0039] It should be noted that the positions of the transmission part 221 and the transmission slot 321 can also be interchanged, that is, the transmission part 221 is arranged on the second connecting shaft 320, and the transmission slot 321 is arranged on the first connecting shaft 220, which will not be described in detail here.

[0040] It can be understood that the transmission structure can also be a structure in which the first connecting ear and the second connecting ear cooperate, and the first connecting ear and the second connecting ear are respectively arranged on the first connecting shaft 220 and the second connecting shaft 320, and the first connecting ear and the second connecting ear are overlapped, and then the first connecting ear and the second connecting ear are fixed by fasteners such as bolts or screws, so that the first connecting shaft 220 can also drive the second connecting shaft 320 to rotate, and there is no limitation here.

[0041] Reference Figure 3 , Figure 4 and Figure 6In some embodiments of the utility model, a partition 400 is further included. The partition 400 is accommodated in the juice extraction chamber 110 to divide the juice extraction chamber 110 into a pre-cut space 112 and a juice extraction space 111. The pre-cut space 112 is located above the juice extraction space 111. The feed channel 120 is communicated with the pre-cut space 112. The partition 400 is provided with an avoidance hole 401. The pre-cut space 112 is communicated with the juice extraction space 111 through the avoidance hole 401. The pre-cut piece 310 is accommodated in the pre-cut space 112. The juice extraction piece 210 is accommodated in the juice extraction space 111. One end of the first connecting shaft 220 away from the bottom of the juice extraction chamber 110 abuts against the partition 400, which can prevent the juice extraction piece 210 from moving up and down during juicing, so as to improve the juicing efficiency of the juicer.

[0042] Specifically, the cup body assembly 100 includes a cup body 101 and a feed cover 102 detachably connected to the cup body, the feed channel 120 is provided on the feed cover 102, the cup body 101 and the feed cover 102 are enclosed to form a juice extraction chamber 110, the partition 400 is located between the cup body 101 and the feed cover 102, and the partition 400 is arranged in the horizontal direction to divide the juice extraction chamber 110 into a pre-cut space 112 and a juice extraction space 111 arranged in the up and down directions, and the pre-cut space The space 112 is located above the juicing space 111, the lower side of the partition 400 abuts against the upper end of the first connecting shaft 220, and the lower end of the first connecting shaft 220 is connected to the output end, the upper side of the partition 400 abuts against the lower end of the second connecting shaft 320, and the upper end of the second connecting shaft 320 abuts against the feed cover 102, thereby avoiding the juicing member 210 and the pre-cut member 310 from moving up and down during juicing, so that the juicing member 210 can stably squeeze the food.

[0043] It should be noted that when the food is softer such as oranges or mangoes, and the food does not need to be cut, the user can only install the juice extraction component 200 and the partition 400 without installing the pre-cutting piece 310 to extract the juice from the food, which is convenient for users and will not be described in detail here.

[0044] It should be noted that there are multiple avoidance holes 401 , which are spaced apart along the axial direction of the cup body assembly 100 , so as to avoid the food from being blocked on the partition 400 , which will not be described in detail here.

[0045] Reference Figure 2 , Figure 3 and Figure 7In some embodiments of the utility model, a filter assembly 500 is further included, which is accommodated in the juice extraction chamber 110.

The partition 400 is provided at one end of the filter element 520 away from the bottom of the juice extraction chamber 110. The partition 400 is connected to the filter frame 510, which can prevent the partition 400 from rotating with the rotation of the food, so as to reduce the noise of the juicer and improve the user experience.

[0046] Reference Figure 7 , Figure 8 In some embodiments of the utility model, the limiting structure includes a limiting portion 511 provided on the filter frame 510 and a limiting groove 113 provided on the cup body assembly 100. The limiting portion 511 is accommodated in the limiting groove 113 and can abut against the side wall of the limiting groove 113, so as to prevent the partition 400 from rotating with the rotation of the food, thereby reducing the noise of the juicer and improving the user experience.

[0047] Specifically, the first limiting groove 113 is located on the bottom wall of the juicing chamber 110, and the first limiting portion 511 is arranged at the lower end of the filter frame 510. When installing the filter assembly 500, the first limiting portion 511 is aligned with the first limiting groove 113. Then, the filter frame 510 is inserted into the juicing space 111 from top to bottom, so that the first limiting portion 511 is inserted into the first limiting groove 113. This can limit the rotation of the filter assembly 500 to avoid the filter assembly 500 rotating with the rotation of the food during juicing, thereby improving the juicing efficiency of the juicer.

[0048] It should be noted that when squeezing juice, the squeezing part 211 squeezes the food to collide with the filter 520 to squeeze the juice. If the first limiting structure is not provided, the filter assembly 500 will rotate with the rotation of the food and the food cannot be squeezed. This will not be described in detail.
