The top end of the encloser 600 has a feed port, a feed passage 603 is defined in the inner of the encloser 600 to communicate with the opening and the feed port 601.

Referring to FIGS. 2-3, the lower end of the encloser 600 defines a connecting element 611, the connecting element 611 is mounted at the top of the juicing cup 100, as such the thread rod 4 sticks into the feed passage 603。

The bottom of the connecting element 611 has an opening, the connecting element 611 defines an inner ring 612 along a circumference of the opening, the inner ring 612 is received in the sieving canister 200, the inner ring 612 is positioned above the top of the thread rod seat 420, and the inner ring 612 and the thread rod seat 420 cooperatively form a second gap 613 (referring to the “d” shown in FIG. 3).

When using the slow juicer, the fruits and the vegetables are put into the feed passage 603 through the feed port 611, and then are preliminarily squeezed to the juice and the pomace. The juice and pomace pass through the opening and flow along the inner surface of the inner ring 612 into the sieving canister 200, so as to prevent the pomace from flowing to the outside of the sieving canister 200, as such, the pomace cannot mix with the juice, and can be completely separated from the juice, which improving the taste of the juice. And, the thread rod seat 420 is mounted at the inner surface of the sieving canister 200, the inner ring 612 is received in the sieving canister 200, to avoid the thread rod 410, the thread rod seat 420 and the sieving canister 200 from hitting the thread rod seat 420 when rotating, the inner ring 12 and the thread rod seat 420 cooperatively form the second gap 613 which can ensure the normal running of the slow juicer.

As the thread rod 410 presses the fruits and the vegetables through rotating, and pushes the fruits and the vegetables to move downwards into the sieving canister 200, the fruits and the vegetables apply the counter-force to the thread rod 410 and the thread rod seat 420 to push the thread rod 410 and the thread rod seat 420 to move upwardly, which may cause the thread rod seat 420 to hit the inner ring 612 located upon the thread rod seat 420. Therefore, the second gap 613 between the thread rod seat 420 and the inner ring 612 must be reasonable.

In detail, referring to FIGS. 4 and 6, the width range of the second gap 613 can be 0.5mm~1mm. If the second gap 613 between the thread rod seat 420 and the inner ring 612 is too small, which may cause the thread rod seat 420 to hit the inner ring 612, and further affect the service life of the slow juicer. And, if the thread rod seat 420 hits the inner ring 612 to produce powder, the power would drop into the juice, as such it would affect the quality and taste of the juice. Therefore, the width range of the second gap 613 should be set as 0.5mm~1mm, which can not only prevent the pomace from mixing with the juice, but also prevent the thread rod seat 420 from hitting the inner ring 612.

In an exemplary embodiment of the present disclosure, the width of the second gap 613 is 0.8mm. As the counter-force pushing the thread rod 410 and the thread rod seat 420 to move upwardly by the rotating juice and pomace is not uniform, which may causing the thread rod seat 420 to shake. When the width of the gap between the thread rod seat 420 and the inner ring 612 is set as 0.8mm, it turns out that the width of the gap with the value of 0.8mm can effectively prevent the thread rod seat from hitting the inner ring 612, and prevent the power from escaping.
