[0034] After the kitchen waste is crushed, the water separated from the filter cartridge 37 enters the liquid storage barrel 50 through the delivery pipe 8; the liquid level of the liquid pipe 55 is equal to the liquid storage barrel 50. When there is too much liquid inside, the gas in the liquid pipe 55 will be compressed, and at the same time, the gas in the upper air pipe 59 will be compressed, and the compression diaphragm 68 will be slightly deformed, so that the top head 73 presses against the lower adjustment piece 67, so that it contacts the upper adjustment piece 74, and then the lead screw 65 forms a loop through the wire 51, and the solenoid valve 52 acts to connect the vacuum source 53 with the film valve 57, so that the film valve 57 is opened, so that the liquid kitchen waste in the liquid storage barrel 50 enters the vacuum pump station 58. When the liquid level inside the liquid storage barrel 50 drops, the liquid pipe 55 also drops, and the compression diaphragm 68 is restored, so that the solenoid valve 52 is closed, so that the atmosphere 54 is connected, and the film valve 57 is closed.

[0035] The air is compressed in the air pipe 59 , and the force exerted on the compression diaphragm 68 is related to the liquid level force of the liquid storage barrel 50 .

The extrusion plate 43 is provided with an open slit.

[0039] The middle part of the screw rod 35 is the middle screw rod 49. The middle screw rod 49 compresses the kitchen waste. Due to the existence of the plastic sleeve 493, adhesion is reduced. The middle screw rod 49 includes an inner blade 491, a middle screw rod body 492, and a plastic sleeve 493. The outer part of the middle screw rod body 492 is provided with [description incomplete in the original, not clear what should be here]. The plastic sleeve 493 is sleeved outside the inner blade 491, and the plastic sleeves 493 cooperate with each other. The plastic sleeve 493 is of a U-shaped structure.
