Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a fruit juice extractor.

[Prior Art] Conventionally, a simple and common method for obtaining fruit juice is to press the fruit against a juice squeezer while moving it to obtain fruit juice from the fruit.

[Problems to be solved by the invention] However, with the above method, there are problems such as the fruit juice scattering or overflowing outside the juice squeezer when squeezing the fruit juice, and it is necessary to press the fruit by hand. This poses a sanitary problem, and fruit peels may also be mixed into the fruit juice, making it difficult to obtain fruit juice that does not contain dregs, such as when trying to feed an infant with fruit juice during the weaning period. It is not appropriate in some cases.

[Means for Solving the Problems] The present invention was invented for the purpose of solving the above problems.

The gist of the present invention is a fruit juice squeezer for obtaining fruit juice by cutting and pressing fruits, which comprises a squeezer body, a handle rotatable with respect to the squeezer body, a mesh member and a sliding member. The mesh member is loosely fitted to the rotating shaft of the handle and is formed at the tip of the cylindrical outer wall of the handle. The protrusion engages with the engagement hole of the perforated plate and is fixed to the perforated plate, the slider is fitted and fixed to the rotating shaft of the handle, and the perforated plate is press-fitted and fixed to the tip of the rotating shaft of the handle. The cutter is loosely fitted into the push-in screw, and the protrusion formed on the outer periphery engages with the engagement groove of the wringer body to be fixed to the wringer body, and the cutter is screwed onto the push-in screw. It is in a juice squeezer.

[Example] Hereinafter, an example of the present invention shown in the drawings will be described in detail.

It consists of a threaded portion 43. The press-fitting portion 41 is press-fitted into the push-in screw hole 40, and the push-in screw 37 is fixed to the rotating shaft 34 and rotates together with the rotating shaft 34. Further, the circular shaft portion 42 is loosely fitted into the shaft hole 28 of the perforated plate 26, so that the perforated plate 26 does not rotate even if the push-in screw 37 rotates. The threaded portion 43 is inserted into the threaded hole 3 of the cutter 27.
2, the cutter 27 rotates together with the push-in screw 37, and the handle 5 connects with the perforated plate 26.
It is attached to the wringer body 1 via. Further, a circular recess 44 is formed in the upper end surface of the rotating shaft 34.

The crank 35 is formed in a U-shape with an open bottom, and a protrusion 45 is formed on the upper side of the crank 35 from the base end to a position corresponding to the periphery of the saucer portion 7 . Further, a knob shaft 46 is formed at the tip of the crank 35;
The knob 36 is rotatably provided with protrusions 47 and 48 engaged with each other.

As shown in FIG. 14, which is a plan view, and FIG. 15, which is a side view, the lid 6 is formed with an inverted shallow bowl-shaped portion 49 that substantially covers the upper surface of the saucer portion 7. The lower end of the outer edge of 49 is positioned above the upper end of the outer edge of the saucer portion 7 with a slight gap therebetween. Further, a crank housing portion 50 having a U-shaped cross section with an open bottom is formed from the center to the outer side of the lid 6.
There is a protrusion 5 on the upper inner wall surface of the crank housing section 50.

To assemble the juice squeezer as described above, first, insert the inner wall 17 of the mesh member 14 into the inner wall hole 22 of the slider 15, engage the protrusion 21 with the protrusion 25, and move the slider 15 to the mesh member. 14 so that it can rotate freely. Next, after placing the perforated plate 26 in the groove 9 of the wringer body 1, it is rotated until it is below the locking piece 10, and the perforated plate 26 is held in the wringer body 1. Perforated plate 2 held in this wringer body 1
6, the integrated mesh member 14 and slider 15 are placed, and the protrusion 20 of the mesh member 14 is placed.
is fitted into the engagement hole 30 of the perforated plate 26 and fixed. Next, in this state, insert the rotating shaft 34 into which the push screw 37 has been press-fitted into the shaft hole 18, the hexagonal hole 23, and the shaft hole 28.
The screw hole 32 of the cutter 27 is screwed into the screw portion 43 protruding from the perforated plate 26. Therefore, the mesh member 14, the slider 15, the perforated plate 2
6. The cutter 27 and handle 5 are the squeezer body 1
The fruit juice squeezer is assembled by holding the fruit juice extractor together.

Next, I will explain how to squeeze the juice. first,
Press the lid 6 onto the handle 5 from above and turn the crank 3
5 is press-fitted into the crank housing part 50, and the lid 6 is placed and fixed on the handle 5. Next, fruits such as mandarin oranges are placed and stored on a fruit mounting stand 11 in the fruit storage part 8, and the handle 5 is rotated while pressing the squeezer main body 1 against the stand 2. Then, the pulp is cut off by the cutter 27 while protruding from the pulp hole 29 of the perforated plate 26, and the juice and skin are separated, and the juice moves to the upper part through the mesh member 14 and accumulates in the saucer part 7. At this time, the fruit juice trying to fly out of the mesh member 14 to the outside of the saucer part 7 hits the bowl-shaped part 49 of the lid 6 which covers the saucer part 7 and rotates together with the handle 5, and falls into the saucer part 7. The pericarp is removed from the fruit juice while being blocked by the mesh member 14. At this time, since the slider 15 slides on the surface of the mesh member 14 due to the rotation of the handle 5, the pericarp left on the surface of the mesh member 14 is removed and the mesh member 14 is prevented from clogging.

[Effects of the Invention] Since the present invention is configured and used as described above, it has the effect of being hygienic because only fruit juice can be easily obtained from fruit. Furthermore, the mesh member, slider, perforated plate, cutter, handle, and push-in screw can be easily attached to the wringer body as one body by fitting or the like, so that they are easy to handle and operate. Furthermore, since the perforated plate is formed into a simple disk shape, it is easy to manufacture and can be manufactured at a low cost.
