The invention discloses an extraction mechanism capable of extracting fruit and vegetable essence. The extraction mechanism comprises an extraction cup, a rubber sealing ring, a bottom spin pressing block and a driving mechanism; a top spin pressing block is movably connected to the cup mouth, the cup bottom is provided with a cup body through hole, and a filter screen is arranged in the cup; the rubber sealing ring is used for being connected with the cup body through hole in a sealed mode, and a through cavity capable of allowing a spinning screw rod to slide is formed in the rubber sealing ring; the bottom of the bottom spin pressing block is provided with a filter hole and a connecting part connected with the upper end of the spinning screw rod, the bottom spin spring block is driven by the spinning screw rod to move back and forth in the extraction cup in a matched mode, and the bottom spin spring block cooperates with the top spin pressing block to squeeze fruit and vegetable raw materials when moving upwards; a filter screen bottom cover and the filter screen bottom are installed in a matched mode; the driving mechanism is used for driving the bottom spin spring block to move back and forth in the extraction cup. According to the technical scheme, due to the fact that the driving mechanism moves up and down in the extraction cup, the fruit and vegetable raw materials are repeatedly squeezed in the cavity, due to the fact that no blade is used for crushing, noise is reduced, fruit and vegetable raw material fiber is not destroyed directly, squeezed normal juice is clean, and the normal juice obtained after being filtered by the filter screen is higher in quality.
