  • the juice extraction device 100 has juice extraction mechanism 300 for extracting juice from food encompassed by a housing 200.
  • the housing 200 has a juice exit 202 from which juice extracted from the food exits, and a residue exit 204 from which remnant remaining after juice extraction exits. Details of the juice extraction mechanism 300 will be described below.
  • An optional push rod 400 is shown, and is used to push food into the juice extraction mechanism 300.
  • an optional driver housing 500 housing the driver (not shown in the figures) is provided, which can also be used to provide support to the housing 200 on a flat surface, like table top.
  • the driver 506 is optional and the juice extraction device 100 can be driven by hand if desired.
  • Optional juice container 502 for holding juice exists from the juice exit 202, and optional residue container 504 for holding reside exits from the residue exit 204 are also shown in Figure 1.
  • the juice extraction device 100 in Figure 1 is in the so-called vertical configuration.
  • FIG. 2 A partial cut away view of the juice extraction mechanism 300 is shown in Figure 2.
  • the juice extraction mechanism 300 has a mesh filter 302 encompassing a hollow juice extraction screw 310.
  • the mesh filter 302 is responsible for separating the juice from the food.
  • the hollow juice extraction screw 310 is capable of being rotated by the driver connected thereto along an axis defining a front an end (shown in Figure 3) , and has a food inlet 320 through which food enters the juice extraction device 300, more specifically to reach the mesh filter 302, for which the entrance can be assisted by the optional push rod 400.
  • the food inlet 320 is shown and preferred to be a separate part from the hollow juice extraction screw 300 in this particular embodiment.
  • the food inlet 320 can be unified with the juice extraction screw 310, but is less preferred as a unified food inlet 320 would have to rotate with the juice extraction screw 310, thus extra load is added to the driver that may reduce juicing efficiency.
  • the juice extraction screw 310 is in general cylindrical shape due to simplicity, it is not necessarily so and other shapes can be used, such as wedge shape. Naturally, if the juice extraction screw 310 is of shape different from cylindrical shape, the shapes of the housing 200, the mesh filter 302 and food inlet 320 have to be adjusted accordingly.
  • the juice extraction mechanism 300 also includes a sweeper 330 for sweeping the food to move along the juice extraction screw 310 when the juice extraction screw 310 rotates.
  • the food moves from the bottom to the top when the juice extraction screw 310 rotates, i.e. against the gravity.
  • the food is viscous and not easy to move, even more so if the food is to be recycled after juice is extracted for the first time.
  • a sweeper 330 is provided, and its detailed operation will be described below. It should be noted that the sweeper 330 is not restricted to the one shown in the figures, but can be anything that can sweep the food when the juice extraction screw rotates, like a piece of relative rigid material such as plastic or metal, or a brush.
  • the juice extraction screw 310 rotates.
  • the position of the sweeper 330 and/or the mesh filter 302 in this invention remain stationary with respect to the juice extraction screw 310 for sweeping the food to move along the juice extraction screw 310.
  • the juice extraction screw 310 is capable of being rotated along an axis with respect to at least one of the mesh filter 302 and the sweeper 330, and it is preferred that the juice extraction screw 310 is rotated about the axis.
  • Figure 3 shows another view of the juice extraction screw 310 with the sweeper 330
  • Figure 4 shows an exploded view of the sweeper 330 in Figure 3.
  • the juice extraction screw 310 has a spiral rib 312 running from the end to the front of the juice extraction screw 310, and defines a plurality of spiral gaps 314 along the length of the juice extraction screw 310.
  • the sweeper 330 has a first set of teeth 336a extending along the direction from the end to the front of the juice extraction screw 310, and this first set of teeth 336a engages the plurality of spiral gaps 314 on the juice extraction screw 310. Between each tooth of the first set of teeth 336a there defines a plurality of teeth gaps.
  • the width of the teeth gaps correspond to the width of the spiral gaps 314, such that when one of the teeth on the first set of teeth 336a engages the spiral rib 312 as the juice extraction screw 310 rotates, all other teeth on the first set of teeth 336a are pushed back (i.e. move in a direction away from the juice extraction screw 310) , or engage the spiral rib 312 at the same time. This preference will become apparent when the detailed operation of the sweeper 330 is explained below.
  • the sweeper 330 of this particular embodiment would work with only this first set of teeth 336a, but the performance of moving food could be improved by providing a second set of teeth 336b to compensate the gaps between the teeth on the first set of teeth 336a. More than two rows of teeth may present, but food moving efficiency may not be much improved with expenses of extra materials and assembly complexity.
  • the first set of teeth 336a, and the second set of teeth 336b if available, are configured to be movable for adapting to motion of the spiral rib 312 when the juice extraction screw 310 rotates. More specifically, the first set of teeth 336a, and the second set of teeth 336b are configured to be movable in a direction normal to the axis of rotation of the juice extraction screw 310, and normal to direction of rotation of the juice extraction screw 310. Generally, it is sufficient for the first set of teeth 336a and the second set of teeth 336b that they are configured to be movable towards and away from the juice extraction screw 310 in any direction.
  • first set of teeth 336a and the second set of teeth 336b are movable in a direction absolutely perpendicular to the axis of rotation of the juice extraction screw 310, and absolutely perpendicular to direction of rotation of the juice extraction screw 310. These movements are to adapt to motion of the spiral rib 312 when the juice extraction screw 310 rotates to minimize impact on the rotation of the juice extraction screw 310. More details of the movements of the first set of teeth 336a and the second set of teeth 336b will be explained below.
  • the height of their teeth in the direction normal to the axis of rotation of the juice extraction screw 310 may be adjusted according to the varying diameter of the juice extraction screw 310.
  • the juice extraction screw 310 of the embodiment shown in Figures 1 to 4 has a smaller diameter closer to the end, and a larger diameter closer to the front. Accordingly, the height of the teeth of the first set of teeth 336a and the second set of teeth 336b are higher for those closer to the end, and shorter for those closer to the front to maintain engagement to the juice extraction screw 310.
  • the sweeper 330 has a sweeper biasing base plate 332
  • a biasing spring 334 is also provided, in this particular embodiment between the sweeper biasing base plate 332 and the two rows of teeth 336a and 336b, for biasing these rows of teeth 336a and 336b to engage the juice extraction screw 310, while allowing two rows of teeth 336a and 336b to be movable in a direction normal to the axis of rotation of the juice extraction screw 310, and normal to direction of rotation of the juice extraction screw 310.
  • two sweeper position fixing plates 338a and 338b are provided to avoid undesirable movement of the two rows of teeth 336a and 336b along the direction of rotation of the juice extraction screw 310.
  • the sweeper 330 is affixed to the mesh filter 302 such that the position of the sweeper 330 in this invention remains to be stationary with respect to the juice extraction screw 310, as mentioned above.
  • the sweeper 330 is affixed to the mesh filter 302 by the sweeper position fixing plate 338b, or if desired, by the sweeper biasing base plate 332.
  • individual tooth of two rows of teeth 336a and 336b can be moveable for adapting to motion of the spiral rib 312 when the juice extraction screw 310 rotates, or more specifically, in a direction normal to the axis of rotation of the juice extraction screw 310, and normal to direction of rotation of the juice extraction screw 310.
  • Another exemplary sweeper 330 is shown in Figure 4A, which has essentially the same construction as that shown in Figure 4. The only difference is that the biasing spring 334 in Figure 4 is replaced by individual biasing springs 334a in Figure 4A.
  • the definition of one set of teeth is that the teeth are arranged in a manner to engage the spiral gaps 314.
  • the teeth can be linked by a common base as shown in the embodiment in Figure 4, or can be individualized as shown in the embodiment in Figure 4A. Further, the number of teeth is a design choice but not restricted. For example, there is only one tooth to engage each spiral gap 314 in the embodiment in Figure 4, but there can be more than one tooth to engage each spiral gap 314 if desired.
  • Figures 5a to 5g shows the operations of the sweeper 330 when the juice extraction screw rotates, in which the block 110 represents food in the juice extraction device 100.
  • the food or the block 110 enters the juice extraction device 100.
  • the sweeper 330 sweeps the block 110 to move from the end to the front.
  • the teeth on the first set of teeth 336a reach the point to engage the spiral rib 312.
  • teeth are configured to be movable in a direction normal to the axis and normal to direction of rotation of the juice extraction screw for adapting to motion of the spiral rib when the juice extraction screw rotates, the teeth are pushed back as shown in Figure 5d to give way to the spiral rib 312 so as to adapt to motion of the spiral rib 312.
  • the depth of the teeth gaps correspond to the depth of the spiral gaps 314 such that when one of the teeth on the first set of teeth 336a engages the spiral rib 312, all other teeth on the first set of teeth 336a are pushed back, or engage the spiral rib 312 at the same time, as, depending on the position of the individual tooth, the other teeth on the first set of teeth 336a may be of some distance from the spiral rib 312 because each tooth has different depth to match with the varying diameter of the juice extraction screw 310.
  • the second set of teeth 336b which is positioned to be complimentary to the teeth gaps of the first set of teeth 336a, now comes into play to sweep the block 110 within the spiral gap 314, and continue to do so in Figures 5e to 5g.
  • the first set of teeth 336a can now "move back”to engage the spiral gap 314, and assists in sweeping the block 110 to move from the end to the front along the spiral gap 314. It can be seen that the two rows of teeth 336a and 336b are biased to engage the juice extraction screw 310 during their operations.
  • the two rows of teeth 336a and 336b cover the entire length of the juice extraction screw form the end to the front.
  • the two rows of teeth 336a and 336b do not have to have the same length. It is preferred that the two rows of teeth 336a and 336b cover the entire length of the juice extraction screw 310 form the end to the front to increase the efficiency of the sweeper 330 and for the sake of engineering simplicity.
  • Juice extraction device 100 in vertical placement also allows an additional advantageous feature of the current invention. Specifically, such vertical placement allows the optional provision of a food recycling conduit 324 to be placed in proximity to the top, that is the front as shown in Figure 3, of the juice extraction device 100. This is preferred such that food can be recycled relatively easily by movement due to gravity.
  • the sweeper 300 is advantageous as the sweeper 330 can be used to sweep or move the recycled food, which tends to be more viscous and/or drier and difficult to be moved.
  • the sweeper of this invention can also be used in juice extraction device in horizontal configuration.
  • the partial cut away view of one such device is shown in Figure 6, in which the references are all increased by 1000 with respect to the juice extraction device 100 shown in Figures 1 to 5g.
  • the juice extraction device 1000 is in horizontal configuration, in which the housing 1200, which has a juice exit 1202, holds the juice extraction screw 1310 encompassed by the mesh filter 1302.
  • the sweeper 1330 is affixed to the mesh filter 1302. The operation of the sweeper 1330 is the same as the sweeper 330.
