[0030] Reference Figures 1 to 6 A juice machine comprises a machine base 1, a juice extraction module 2 and a barrel 3.

[0031] The base 1 is provided with a motor 11 and the motor 11 has a driving shaft 12 extending through the top of the base 1 ; a mounting seat for mounting the juice extraction module 2 is also formed on the top of the base 1 .

[0032] The juice extraction module includes a juice barrel 21, a juice cup 22 and a screw 23. The juice cup 22 is arranged in the juice barrel 21 and a juice storage space 24 is formed therebetween. The screw 23 is placed in the juice cup 22. The drive shaft 12 penetrates into the juice extraction module 2 and is transmission-connected to the screw 23. Specifically, the screw 23 has a transmission shaft 29. The transmission shaft 29 is transmission-connected to the drive shaft 12 through a sealing penetration from the bottom of the juice barrel 21. The specific sealing penetration method is similar to that of a traditional juicer and will not be described in detail herein. The motor 11 drives the screw 23 to rotate and cooperate with the juice cup 22 to squeeze the food to extract juice, and the juice flows into the juice storage space 24 through the mesh wall of the juice cup 22; the juice barrel 21 is provided with a juice outlet 25 and a residue outlet 26, and the bottom of the juice cup 22 is provided with a residue outlet 27, the juice outlet 25 is connected to the juice storage space 24, and is used to discharge the juice stored in the juice storage space 24, and the residue outlet 26 is connected to the residue outlet 27, and is used to discharge the waste residue discharged from the residue outlet 27 after the food is squeezed by the screw 23.

[0033] The barrel 3 is installed above the juice extraction module 2 and the bottom cover of the barrel 3 is arranged on the top opening of the juice barrel 21 and the juice cup 22. The barrel 3 has upper and lower openings. The upper opening can also be arranged with an auxiliary cover for assisting in putting in food. The lower opening is connected with the top opening of the juice cup 22. A support part 31 is provided at the lower opening of the barrel 3. The hollowing between the support part 31 and the inner wall of the lower opening forms a feeding opening 32. A cutting knife 33 driven by the screw 23 is installed on the support part 31. The cutting knife 33 rotates synchronously with the screw 23 to cut the food put into the barrel 3. The user can directly put in the whole fruits and vegetables, and there is no need to cut the food into small pieces in advance before juicing. This greatly reduces the user's work and is more convenient to use.

[0034] The middle part of the support part 31 is formed with a connection seat 311 for mounting the cutting blade 33, and a rotating head 35 is installed in the connection seat 311. The cutting blade 33 is located above the connection seat 311 and fixed to the rotating head 35. The top of the transmission shaft 29 of the screw 23 penetrates from the bottom of the connection seat 311 and is connected to the rotating head 35 for transmission to achieve synchronous connection with the cutting blade 33, and is positioned up and down with the lower driving shaft 12 through the connection seat 311 to maintain stable rotation; the bottom of the support part 31 is connected to the rotating head 35 through the connection seat 311. A recess 312 is formed between the lower open wall surfaces, and a protrusion 231 is provided on the top of the blade of the screw 23 to extend into the recess 312. The arrangement of the recess 312 and the protrusion 231 increases a space above the screw 23 that can contact more parts of the food. During the rotation of the screw 23, the recess 312 and the protrusion 231 can further cut the food and stably cut the food into the juicer cup 22 each time the protrusion 231 passes through the recess 312, thereby maintaining stable juicing work and improving the juicing efficiency of the juicer.

[0035] like Figures 7 to 9 As shown, as a preferred solution, the thickness of the support portion 31 where the concave position 312 is located gradually becomes thinner facing the rotation direction of the screw 23 and forms a cutting edge 313. When the protrusion 231 on the top of the screw 23 pushes the food close to the concave portion, the food can be easily cut off by the cutting edge 313 and the cut food can be smoothly brought down by the screw 23. Furthermore, the cutting edge 313 is in an inner arc shape to increase the length of the cutting edge 313, and the inner arc cutting edge 313 can better hold the food so as to cut off a sufficient size and put it into the juicer cup 22 for squeezing, further improving the juice extraction efficiency. Furthermore, the side wall of the connecting seat 311 is arched to form a guiding arc surface 314, and the recessed position 312 forms a channel which gradually narrows from the cutting edge 313 through the guiding arc surface 314. After the cut food enters the recessed position 312 under the cooperation of the recessed position 312 and the convex portion, it starts to be initially squeezed through the above-mentioned channel and works better with the blade of the screw 23; and a guiding platform 36 is convexly provided on the inner wall of the barrel 3 in the recessed position 312, and the height of the guiding platform 36 gradually decreases downward facing the rotation direction of the screw 23 to form a downward guiding slope, so that the food can enter the juice cup 22 more smoothly.

[0036] As a preferred solution, the protrusion 231 on the top of the blade of the screw 23 can be provided in various forms to match the recess 312. Fig.10 As shown in the first embodiment, the protrusion 231 is a baffle extending along the edge of the blade. The baffle-like protrusion 231 is arranged along the blade, which can fully guide the food so that the food enters the blade and is guided downward to be squeezed. Fig.11As shown, as a second embodiment, the protrusion 231 is a hook claw protruding from the top of the blade, which can hook the food and bring it completely out of the recess 312 and smoothly into the juice cup 22, preventing the food from leaving residue in the dead corner.

[0037] As a preferred solution, the lower part of the barrel 3 is provided with an inclined wall surface 37 extending to the opening of the juice cup 22 and engaging with the inner wall of the juice cup 22, playing a guiding role so that the food can smoothly enter the juice cup 22. The wall surface of the lower part of the barrel 3 is circumferentially arranged with multiple convex ribs 38 to prevent the food from rotating with the cutting knife 33 and being unable to be cut. The support part 31 is a crossbeam component integrally formed in the middle of the inner wall of the barrel 3, which has sufficient rigidity to support the cutting knife 33 and serve as the top positioning base of the screw 23, and can maintain stable cooperation with the convex part of the screw 23. In addition, when installing the rotating head 35, a wear-resistant sleeve 34 can be arranged on the connecting seat 311, and the wear-resistant sleeve 34 is used to form an installation cavity for installing the rotating head 35. The wear-resistant sleeve 34 is used to prevent the rotating head 35 from wearing the connecting seat 311 under long-term rotation, resulting in a large gap between the rotating head 35 and the connecting seat 311, resulting in shaking.
