Discharge orifice on lower float chamber 18 includes bottom drain hole 19 and side wall discharge orifice 20；Wherein side wall discharge orifice 20 divides Positioned at the top position of side wall and positioned at side wall two kinds of position on the lower, to be preferably located at the top position of side wall.

In addition, bottom drain hole 19 and the net area of gross area ﹤ inlets 6 positioned at the side wall discharge orifice 20 at position on the lower (area of 6 net areas of inlet=inlet 6 subtracts the area after connecting rod or other component occupied areas), can so make to float downward The speed that the side wall discharge orifice 20 at the bottom drain hole 19 of seed cell 18 and side wall position on the lower flows out fruit juice is less than and passes through inlet 6 The speed of fruit juice is flowed into, so that fruit juice, after inlet 6 flows into lower float chamber 18, some fruit juice stagnant can have it Inside, so that lower float 17 can float up in the presence of buoyancy.

In addition, the area of side wall discharge orifice 20 positioned at top position can be more than the net area of inlet 6, under can so making Can quickly it be flowed out when fruit juice is excessive in float chamber 18.

Lower float chamber 18 is preferably hollow cup-shaped, and it is connected with the outer surface of cavity 4 with fixation/removably.

In addition, connecting rod 21 is the thicker reducing bar of straight-bar or top, at least part of diameter is less than feed liquor on connecting rod 21 6 diameters of mouth.Highly it is H from the inwall of cavity 4 to the lower inner bottom part of float chamber 18, the wall thickness of cavity 4 is H1, the lower height of of float 17 itself Spend for H2, the length of connecting rod 21 is H3, then H1+H2+H3 ﹤ H.As H be 3 centimetres, H1 be 0.3 centimetre, H2 be 0.7 centimetre, H3 1 Centimetre so that when not having liquid in lower float chamber 18, float 7 can be automatically fallen off, thus by float 7 itself or The top thicker part position of connecting rod 21 blocks inlet 6.

The effect of lower float chamber 18 and lower float 17 is set in the present embodiment is：When float 7 are only carried, It can rise float 7 when fruit juice is flowed into cavity 4 and influx is enough, so as to open inlet 6, flow into fruit juice and connect juice appearance In device 1.But when fruit juice will fully flow into and connect juice container 1 because fruit juice in cavity 4 very little, buoyancy it is too small, deficiency So that float 7 floats, when so as to cause to there remains a small amount of fruit juice in cavity 4, float 7 has just fallen and has blocked feed liquor Mouth 6 so that remaining a small amount of liquid juice, which can not be flowed into all, in cavity 4 connects in juice container 1.And with lower float chamber 18 and float downward After son 17, because the stagnant fruit juice deposited can float lower float 17 in lower float chamber 18, so as to push up float 7, make its hysteresis few Perhaps the time falls and blocks inlet 6 completely again, fruit juice having time remaining in cavity 4 is fully flowed into and connects juice container In 1.

The automatic-sealed for the vacuum juicer that the present embodiment provides connects juice container and waited when in use, first by the outer end of cavity 4 Mouth connects with vacuum juicer juice opening 5, after vacuum juicer starts, is first evacuated inside vacuum juicer, and then causes The inside and outside generation pressure difference of juice container 1 is connect, as a result float 7 is raised above in the presence of pressure difference, connects in juice container 1 and taken out very It is empty；Further, fruit juice is made in vacuum juicer to flow out from juice opening 5, into cavity 4 so that float 7 is again by fruit juice Caused buoyancy force, then fruit juice flows into lower float chamber 18 by inlet 6, then passes through the lower bottom drain hole 19 of float chamber 18 And/or side wall discharge orifice 20 flows into and connects the bottom of juice container 1.

Because bottom drain hole 19 and/or the gross area positioned at the side wall side wall discharge orifice 20 at position on the lower are less than inlet 6 net areas, so that (especially lower position) total hysteresis has a part of fruit juice in lower float chamber 18, what the fruit juice provided Buoyancy can rise lower float 17, and (meanwhile the area of side wall discharge orifice 20 at the lower top position of the side wall of float chamber 18 is larger, and this causes When fruit juice is more in lower float chamber 18, fruit juice can be flowed rapidly into by greater area of side wall discharge orifice 20 and connect juice container 1 It is interior).At this moment the fruit juice that vacuum juicer makes just makes remaining in cavity 4 close to fully flowing into after automatic-sealed connects juice container 1 Fruit juice is insufficient to allow float 7 to float, but (lower portion) still has liquid juice in lower float chamber 18, and the fruit juice to float downward Son 17 rises and further (by connecting rod 21 or directly jack up) jack-up float 7, float 7 is made from blocking inlet 6 Remaining fruit juice can smoothly be flowed into and connect in juice container 1 in cavity 4；After fruit juice has all flowed in cavity 4, in lower float chamber 18 Fruit juice slowly flow into and connect in juice container 1 also by bottom drain hole 19, lower float 17 is sunk, float 7 also and then sinks, most Afterwards inlet 6 is blocked by the bottom of float 7, or by " upper diameter of connecting rod 21 is relatively thick, diameter is more than the position (connecting rod of inlet 6 Middle part, lower diameter are less than inlet 6) " block inlet 6.

After vacuum juicer is shut down, vacuum state is released using vacuum juicer itself relief valve, but now because of float 7 Closure is at inlet 6, so it is still vacuum state to connect in juice container 1, opens vacuum juicer juice opening 5 and the outer end of cavity 4 The sealed connection of mouth, connects in juice container 1 and still keeps vacuum, fruit juice is obtained vacuum preservation.
