As shown in fig. 2 and 4, the juice sealing structure comprises an isolation space 6 which is at least partially arranged around the side wall of the slag receiving container 5. In this embodiment, the isolation space 6 is circumferentially arranged around the upper port of the slag receiving container, so that the isolation space 6 forms the only path which is communicated with the outside between the upper port of the slag receiving container 5 and the extrusion container 3. The isolating space 6 can be one or more, in this embodiment, it is an annular isolating space 6, when the juice machine is in a non-working state, or in a working state and the liquid level of the juice in the juice receiving container is lower and has not reached the isolating space, the isolating space 6 communicates the inside of the residue receiving container with the outside, when the juice in the juice receiving container rises along with the liquid level and at least partially enters the isolating space, the isolating space 6 immediately seals the air in the residue receiving container, and the juice entering the isolating space compresses the air in the residue receiving container in a closed state to form an internal and external pressure difference. The radial distance between the outer wall of the extruding cylinder 3 and the inner wall of the juice receiving container 4 is at least partially reduced from top to bottom, so that the effective volume space of juice in the juice receiving container 4 is increased, and the requirement of making single or multiple fruit and vegetable juice at one time is met.

Specifically, the extrusion cylinder 3 includes an annular side wall 31 and a bottom wall 32, the bottom wall 32 is located the annular side wall lower end is equipped with the filter part 35 on the annular side wall 31, is equipped with the slag discharge hole 321 on the bottom wall 32, still is equipped with the shutoff on the extrusion cylinder bottom wall 32 the elasticity chock 322 of slag discharge hole. 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.

As shown in FIG. 5, a height difference h1 is formed between the lower end surface of the annular surrounding edge 311 and the upper end opening of the slag receiving container 5, h1 is greater than or equal to 0.5mm and less than or equal to 70mm, the gap value of the gap is I, I is greater than or equal to 0.1mm and less than or equal to 25mm, in the embodiment, h1 is 7mm, and I is 2mm, so that the reliability of sealing juice and the sealing performance of the space formed in the slag receiving container 5 are ensured, and the height difference and the gap value directly relate to the height at which the liquid level can rise, namely the effective juice capacity of the juice receiving container 4, and also directly influence the juice sealing effectiveness of the isolation space 6.

To ensure that the insulation space 6 is effective and reliable in sealing the juice, the air pressure inside the slag receiving container 5 is not less than the air pressure outside the slag receiving container, i.e. P_{Inner max}≥P_{Outer cover}Since the juice receiving container 4 is connected with the main machine 1 and the connection part has no sealing structure, the air pressure inside the juice receiving container is the same as the air pressure outside the juice receiving container and is also the same as the air pressure outside the dreg receiving container. In this embodiment, V is the volume of the isolation space, P0 is the air pressure outside the residue receiving container, V0 is the volume of the residue receiving container, and ρ is the density of the juice in the juice receiving container. During the juicing process, when the juice is just filled in the cross section of the bottom end of the isolation space 6, the air pressure in the residue receiving container 5 is equal to the air pressure outside the residue receiving container by P0, and the volume of the isolation space 6 is not yetIs compressed, and ideally, when the liquid level of the juice rises to a certain degree, a critical value exists, namely the liquid level just reaches the top end of the isolation space, namely the upper port of the slag receiving container 5, and at the moment, the air in the slag receiving container is compressed to the limit of P_{Inner max}When the room temperature is T, P0(V0+ V)/T ═ P is provided_{Inner max}V0/T, from which P is known_{Inner max}P0(V0+ V)/V0. And the air pressure P outside the slag receiving container 5_{Outer cover}Where h is the distance between the upper port of the slag receiver and the liquid level, and the maximum height which can be reached by the liquid level is the upper port of the juice receiver, i.e. h is not greater than the distance between the upper port of the juice receiver 4 and the upper port of the slag receiver 5. Will P_{Inner max}And P_{Outer cover}Respectively substituted into P_{Inner max}≥P_{Outer cover}And then, the distance range between the upper port of the juice receiving container and the upper port of the residue receiving container can be obtained, namely the height range of the liquid level of the juice which can not enter the residue receiving container can be ensured.

The distance between the upper end opening of the juice receiving container 4 and the upper end opening of the slag receiving container 5 is h0, when the volume of the isolated space is fixed,

obviously, the height that can be reached by the juice is related to the volume of the isolated space and the distance h0 between the upper port of the juice receiving container 4 and the upper port of the slag receiving container 5, so that not only does the juice reach the inside of the slag receiving container, but it must be satisfied that the air pressure outside the slag receiving container is not greater than the air pressure inside the slag receiving container, and as the liquid level rises, the amount of juice entering the isolated space gradually increases, and correspondingly, the air inside the slag receiving container 5 is gradually compressed, and the air pressure inside the slag receiving container 5 is increased. The pressure in the isolation space and the air pressure in the residue receiving container 5 can bear the juice pressure above the isolation space, the highest height that the juice can reach is the upper port of the juice receiving container, at the moment, the balance relation between the pressure difference between the inside and the outside of the residue receiving container 5 and the juice pressure can be met, the juice cannot enter the residue receiving container 5, the effective juice receiving capacity of the juice receiving container 4 can reach the maximum value, and the residue receiving container and the juice receiving container are designedThe optimal volume ratio of the juice container is achieved, so that the structure of the whole machine is achieved, the optimal design of the juice receiving and residue receiving capacity is achieved, the material cost is greatly saved, the waste is minimum, and the user experience is optimal.
