The lower end of the annular side wall 31 is inwardly retracted and downwardly extends to form an annular surrounding edge 311, at least part of the side wall of the slag receiving container is sleeved in the annular surrounding edge 311, a gap is formed between the annular surrounding edge 311 and the side wall of the slag receiving container 5 to form the isolation space 6, the lower end surface of the annular surrounding edge 311 is not higher than the upper end opening of the slag receiving container 5, a height difference is formed between the lower end surface of the annular surrounding edge 311 and the upper end opening of the slag receiving container 5, the height difference is the height of the isolation space, the gap value of the gap is the width of the longitudinal section of the isolation space, the isolation space 6 is arranged around the upper end of the outer side wall of the slag receiving container 5, and the whole extrusion cylinder 3 is covered on the upper end opening of the slag receiving container 5, so that the inside of the slag receiving container 5 is sealed through juice in the isolation space 6. When the juice is higher than the isolation space 6, the inside and the outside of the residue receiving container form air pressure difference, so that the juice is prevented from further entering the residue receiving container 5, the juice amount in the juice receiving container is greatly increased, and the juice drunk by one person and multiple persons can be made. And along with the increase of juice in the juice receiving container, the difference of the upper weight and the lower weight of the juice machine becomes smaller, the whole machine works more stably, the situation that the weight of the whole machine is heavy and the weight of the whole machine is light due to the fact that the main machine is arranged on the upper portion is avoided, the juice machine is not prone to toppling, and the juice in the juice receiving container 4 can be better stored.
The diapire of recipient 3 and seal juice structure will connect the inside sealed cavity that forms of sediment container, the juice that connects in the juice container can't enter into and connect in the sediment container 5, and arrange the sediment in-process, the elasticity chock 322 is at least partly by the liftout but arrange the juice of sediment mouth 321 by material sediment and recipient diapire and totally seal, and connect between sediment container 5 and the recipient 3 again by seal juice structure seals, consequently connect still to form sealed cavity in the sediment container to connect and form effectual pressure differential between the sediment container is inside and outside, guarantee that the juice can continuously rise to connect the position above the upper end mouth of sediment container 5 and the juice can't enter into and connect the sediment container inside. In addition, the isolation space allows at least partial juice to enter, so that the air volume in the residue receiving container 5 is compressed, the juice cannot further enter the residue receiving container, when the residue is continuously filled in the residue receiving container, the air volume in the residue receiving container is further compressed, part of air is discharged into the juice outside the residue receiving container through the isolation space 6 in a micro-bubble mode, and the air rises to the liquid level of the juice and is discharged to the outside, and therefore the effect of one-way gas conduction is formed, and residue discharge is smooth and rapid.
In the present embodiment, the squeezing assembly and the residue receiving container 5 form an extending part extending into the juice receiving container 4, and the volume of the extending part is V1 and 300cm3≤V1≤500cm3In this example, V1 is 415cm3The whole machine is small and portable, the juicing efficiency is high, the feeding efficiency is matched with the juicing efficiency, the uniformity of the precision value of the crushing gap between the screw rod and the extruding cylinder is good, the material entering the extruding and crushing gap can be accurately cut by the screw on the screw rod, and the problem of material returning is avoided.

7. The juicer of claim 6 wherein the juice-sealing structure includes an isolation space defined by a gap between the annular skirt and the sidewall of the grounds-receiving container, wherein juice at least partially enters and seals the isolation space to form the first enclosed volume within the grounds-receiving container.
8. The juicer of claim 2 wherein the container includes an annular sidewall having the filter portion disposed thereon, the dividing bottom wall being disposed at a lower end of the annular sidewall.
9. The juicer of claim 7 wherein the separation space has a volume V, wherein P0 is the air pressure outside the residue receiving container, V0 is the volume of the residue receiving container, rho is the density of juice in the juice receiving container, and h is the distance between the upper port of the residue receiving cup and the liquid level of the juice when the liquid level of the juice in the juice receiving container is higher than the upper port of the residue receiving cup.
