[0029] A barrel 1.1 is provided on the top of the upper cover 1, and the barrel 1.1 is communicated with the juice extraction net 3. The slag discharge system further comprises a push rod 9, and the push rod 9 is movably arranged on the barrel 1.1.

[0030] The bracket linkage is an electromagnet 8, and a control circuit board 6 is provided on the upper cover 1. The control circuit board 6 is electrically connected to the electromagnet 8. A push rod 9 is located on one side of the control circuit board 6. A button 6.1 is provided on one side of the circuit board 6. A push rod 8.1 is provided at one end of the electromagnet 8. The push rod 8.1 is linked to the scraping bracket 4. When the juicer is working, the user first puts the food into the barrel 1.1, and then presses the push rod 9 down, and the food falls into the juice extraction net 3 for juicing. When the push rod 9 moves downward, it touches the button 6.1 of the control circuit board 6. The control circuit board 6 electronically controls the electromagnet 8 to work within a specified time, so that the push rod 8.1 extends and drives the scraping bracket 4 to rotate outward, and links the scraping bracket 4 to rotate outward to achieve slag discharge. After slag discharge, when the user lifts the push rod 9 upward to prepare for the next feeding, the control circuit board 6 controls the electromagnet 8 to reset, and the push rod 8.1 retracts and drives the scraping bracket 4 to reset. The bracket linkage can also be a component that needs to be electrically connected, such as a motor, and the scraping bracket 4 is rotated by the motor linkage.

[0031] A circuit board cover 7 is mounted on the upper cover 1. The circuit board cover 7 is disposed above the control circuit board 6 and the electromagnet 8. The circuit board cover 7 protects the control circuit board 6 and the electromagnet 8 to prevent them from being disturbed by the outside world and affecting their operation.

[0032] The push rod 8.1 is provided with an axial hole 8.2, and the top of the scraper bracket 4 is provided with a linkage shaft 4.2, which is inserted into the axial hole 8.2 so that the push rod 8.1 and the scraper bracket 4 form a linkage.

[0033] The scraper bracket 4 is provided with a rotating hole 4.1, and the upper cover 1 is provided with a rotating shaft, which is inserted into the rotating hole 4.1. The scraper bracket 4 is rotatably connected to the upper cover 1 through the cooperation of the rotating shaft and the rotating hole 4.1, so that the scraper bracket 4 can rotate around the upper cover 1.

[0034] One end of the scraper bracket 4 is provided with a touch opening 4.3, and a slag discharge channel 4.4 is provided in the scraper bracket 4. The slag discharge channel 4.4 is connected to the slag discharge pipe 5.

It is concluded from multiple experiments that the slag discharge pipe 5 with this arc structure is the best flying trajectory for slag, which can achieve efficient slag discharge.

[0036] The motor 10 is arranged at the bottom of the base 2 , and the output shaft of the motor 10 is drivingly connected to the juice extraction net 3 .

[0037] Juicer working principle:

[0038] When the juicer is working, the motor 10 drives the juice extraction net 3 to rotate, and the user can put the food into the barrel 1.1 of the upper cover 1, and then press the push rod 9 downward. Under the downward pressure of the push rod 9, all the food falls into the juice extraction net 3. When the juice extraction net 3 rotates, the food is thrown to the inner wall 3.1 of the juice extraction net 3 for centrifugal juice extraction. When the push rod 9 is pressed downward, it touches the button 6.1 of the control circuit board 6. The control circuit board 6 electronically controls the electromagnet 8 to work within a specified time, so that the push rod 8.1 extends and drives the scraper bracket 4 to rotate outward. The contact opening 4.3 of the scraper bracket 4 touches the inner wall 3.1 of the juice extraction net 3, and the residue on the inner wall 3.1 of the juice extraction net 3 is thrown into the residue discharge pipe 5 through the residue discharge channel 4.4, and is discharged out of the juicer along the residue discharge pipe 5 with a specific arc. After the residue is discharged, when the user lifts the pushing rod 9 upward to prepare for the next feeding, the control circuit board 6 controls the electromagnet 8 to reset, so that the pushing rod 8.1 shrinks back and drives the scraper bracket 4 to rotate inward and reset, and then the user can continue the continuous working cycle of feeding - juicing - residue discharge.

[0039] Second embodiment

[0040] The juice extractor with a fully automatic residue removal system is different from the first embodiment in that:

[0042] Juicer working principle:

[0043] When the juicer is working, the motor 10 drives the juice extraction net 3 to rotate, and the user can put the food into the barrel 1.1 of the upper cover 1, and then press the push rod 9 downward. Under the downward pressure of the push rod 9, all the food falls into the juice extraction net 3. When the juice extraction net 3 rotates, the food is thrown to the inner wall 3.1 of the juice extraction net 3 for centrifugal juice extraction. When the push rod 9 is pressed downward, the linkage slider slides on the upper cover 1. When the slider slides on the upper cover 1, the linkage scraping bracket 4 rotates outward, and the scraping bracket 4 The contact opening 4.3 touches the inner wall 3.1 of the juice extraction net 3, and the slag on the inner wall 3.1 of the juice extraction net 3 is thrown into the slag discharge pipe 5 through the slag discharge channel 4.4, and is discharged out of the juicer along the slag discharge pipe 5 with a specific arc. After the slag is discharged, the user lifts the push rod 9 upward to prepare for the next feeding. The slider is linked to the slag scraping bracket 4 to rotate inward and reset under the elastic force of the spring, and then the user can continue the continuous working cycle of feeding - juicing - slag discharge.
