Description

Technical Field

[0002] An oil press is a machine that uses mechanical external force to increase the temperature, activate oil molecules, and squeeze oil out of oil. After oil pressing, the oil residue will flow out with the oil. After long-term use, the oil residue will accumulate on the filter screen, affecting the oil extraction efficiency.

[0003] Chinese patent publication number CN210453871U discloses an oil press equipped with a scraper device. The impurity filter 12 filters the squeezed oil, and the residue is retained on the impurity filter. The scraper motor starts to work, driving the cleaning shaft on the rotating end. The cleaning shaft drives the cleaning scraper to clean the residue retained on the impurity filter. The cleaned residue is discharged through the second slag discharge port, and the filtered oil is finally discharged through the oil outlet, which effectively improves the oil pressing effect. The scraper mechanism located in the oil press body can effectively filter and clean the impurities in the squeezed oil, prevent the oil outlet from being blocked, and improve the oil pressing effect.

[0004] However, the above patent has the following shortcomings:

[0005] The oil press can only push the waste residue on the front side of the cleaning scraper out of the residue discharge port for cleaning, but cannot clean the waste residue on the back side of the cleaning scraper. After long-term use, the waste residue will accumulate on the back side of the cleaning scraper, reducing the oil output efficiency. Utility Model Content
