A filter cylinder 4, a canopy 5 attached to the upper opening of the bottle 1, a cap 6 for closing a material charging port formed at the center of the canopy 5, and a built-in drive motor (not shown), these bottle 1, bottom lid 2, A main body 7 (FIG. 1) on which an assembly of a bottle base 3, a filter cylinder 4, a canopy 5 and a cap 6 is placed is provided.

  The bottle 1 is made of transparent glass in this embodiment. A male screw 11 is formed on the outer periphery of the lower opening of the bottle 1, and a rib 12 is formed on the inner surface of the bottle 1 for ensuring the strength.

  The bottom lid 2 includes a bearing that supports a rotating shaft 22 that is perpendicular to a metal plate 21 that is large enough to cover the lower opening of the bottle 1. A cutter 23 is provided at the upper end of the rotating shaft 22 (inside the bottle 1), and the lower end of the rotating shaft 22 (outside of the bottle 1) receives the rotational force of a drive motor (not shown) built in the main body 7. A spur gear 24 (FIG. 2) is formed to be transmitted to the cutter 23. The metal plate 21 has a convex portion 25 concentric with the rotation shaft 22. A rubber seal 26 that abuts against the lower opening end of the bottle 1 is interposed on the upper surface of the metal plate 21.

The bottle base 3 includes an upper cylindrical portion 31 in which a female screw 32 corresponding to the male screw 11 formed in the lower opening of the bottle 1 is formed, a bottom lid receiving portion 33 extending inward from a position below the female screw 32, and a bottom A lower cylindrical portion 34 that protrudes downward from the lid receiving portion 33 and has a fold 35 for preventing rotation of the bottle base 3.

The lower opening of the bottle 1 is sealed.
The center of the bottle base 3 has a large opening, and the rotational force supplied from the main body 7 is directly transmitted to the spur gear 24 of the bottom lid 2 through this opening.

  The filter cylinder 4 is composed of two parts, a mesh holding body 40 and a mesh guard body 45.

Among these, the mesh holding body 40 is a cylindrical body in which a vertically long window portion 42 (FIG. 1) is formed over the upper half, and liquid is applied to the inside of the cylindrical body so as to cover the entire window portion 42. A mesh 41 (FIG. 3A) of a synthetic fiber to be permeated is stretched. A plurality of window portions 42 to which fiber mesh is stretched are formed in the circumferential direction of the cylinder, and a window frame portion 43 (FIG. 1) between each window 42 and the window portion 42 extends in the vertical direction of the cylinder. . A flange 44 extending outside the cylindrical body is formed below the window portion 42. The flange 44 extends to the vicinity of the inner surface of the bottle 1 with a gap between the inner surface of the bottle 1 and a recess corresponding to the rib 12 on the inner surface of the bottle 1 is also formed. It is desirable to attach a rubber seal that provides a sealing action with the bottom lid 2 when the mesh holder 40 is fitted to the convex portion 25 of the bottom lid 2.
According to this, in the state where the bottom lid 2 and the bottle 1 are set on the bottle base 3 and the lower opening of the bottle 1 is closed, the filter cylinder 4 is inserted from the upper opening of the bottle 1 and the lower end of the filter cylinder 4 is inserted. Is fitted into the convex portion 25 of the bottom cover 2, the cutter 23 is accommodated in the filter cylinder 4.
As shown in FIG. 1, the shape of the window portion 42 is such that the left and right window frames 43 are parallel in the upper half, but the width in the lower half becomes narrower as it goes downward. More specifically, the window frame 43 on the downstream side of the rotational flow by the cutter 23 is inclined so that the rotational position changes from the upper side to the lower side. The effect of this will be described later.

  The mesh guard body 45 is also a cylinder, and includes a small diameter portion 46 at the upper end and a slit portion 47 extending from the lower end to a length corresponding to the window portion 42. A large number of slits (small openings) are formed in the slit portion 47 and inserted into the mesh holding body 40 to protect the fiber mesh 41 of the mesh holding body 40 from violent water flow in the filter cylinder 4. Spacer ribs 48 are formed on the outer periphery of the slit portion 47, and a gap is formed between the slit portion 47 and the fiber mesh 41 by the spacer rib 48.

  The canopy 5 includes a rubber seal 51 that seals between the inner surface of the bottle 1 and the vicinity of the upper opening, and a stopper 52 that contacts the upper end of the bottle 1, and a circular material inlet 53 (FIG. 1) is formed at the center. Yes. The inner diameter of the material inlet 53 is formed to be substantially the same as the inner diameter of the small diameter portion 46 at the upper end of the mesh guard body 45 of the filter cylinder 4.

  The cap 6 has a shape in which the upper end 62 of the cylindrical portion 61 is closed. The cap 6 is configured such that the cylindrical portion 61 is inserted into the material charging port 53 of the canopy 5 from the lower end side thereof, and closes the upper opening of the bottle 1 together with the canopy 5. The cap 6 inserted into the material inlet 53 of the canopy 5 is further inserted into the small diameter portion 46 at the upper end of the mesh guard body 45 of the filter cylinder 4 so that the lower end of the cap 6 presses the upper end of the filter cylinder 4. ing.

  The main body 7 includes a spur gear 72 connected to a built-in drive motor (not shown) at the center of a recess 71 that can accommodate the bottle base 3. The bottle base 3 to which the bottle 1, the bottom lid 2 and the like are fixed is placed in the recess 71 of the main body 7, and a drive motor (not shown) is driven to rotate the rotating shaft via the spur gear 72 and the spur gear 24. A rotational force can be transmitted to 22 and the cutter 23 can be rotated.

By introducing ingredients such as fruits, vegetables, beans, leaf tea, and water and milk into the filter cylinder 4 from the material inlet 53 as required, and closing the material inlet with the cap 6 and rotating the cutter, The ingredients are crushed. And according to the input foodstuff, drinks, such as fruit juice, vegetable juice, soy milk, and watering tea, are discharge | released out of the filter cylinder 4. FIG. Since the discharged beverage accumulates in the bottle 1, it is poured into a glass or the like for drinking.
In addition, it is also possible not to use the filter cylinder 4 but to grind or agitate the food material as a “mixer” that is not the juice mixer of the present invention.

FIG. 3B shows another embodiment of the present invention, and a window opened on the side surface of the cylindrical mesh holder 40b as in the embodiments of FIGS. 1, 2, and 3A. A fiber mesh 41b is stretched on the part. However, unlike the window portion 42 shown in FIG. 1, the window portion has a rectangular shape. That is, the left and right window frames 43b are parallel from the upper end to the lower end. Further, the mesh guard body 45 is not provided.
When the embodiment of FIG. 3B is actually used, fine particles are blocked by the use of the fiber mesh 41b, and a delicious beverage can be created. However, the use with hard ingredients such as raw soybeans is repeated many times. Among them, an example in which a part of the fiber mesh 41b was damaged was observed.
This is presumably because the hard food that has not yet been finely pulverized comes into contact with the fiber mesh 41b violently due to the intense rotational flow inside the mesh holder 40b. In particular, the breakage of the fiber mesh 41b occurred on the downstream side of the rotating flow in the window portion. From this, the fiber mesh 41b bends outward as indicated by the alternate long and short dash line in FIG. 3 (B), and the food meshes with the bent fiber mesh 41b and collides in front with the window frame 43b. This is considered to be a major cause of breakage of 41b.
Therefore, as shown in FIG. 1, an inclined portion is provided at the lower end portion of the window portion 42 where the rotational flow is particularly intense, and unground food can escape upward along the inclined portion without causing a frontal collision with the window frame 43. As a result, breakage of the fiber mesh 41 could be reduced. In addition, by providing the mesh guard body 45, it was possible to avoid large foods from coming into contact with the fiber mesh 41 and reduce damage to the fiber mesh 41. By combining these, breakage of the fiber mesh 41 could be further reduced. Note that spacer ribs 48 were formed on the mesh guard body 45 to avoid contact between the fiber mesh 41 and the mesh guard body 45 in order to avoid a decrease in moisture transmission efficiency in the fiber mesh 41.

  Each of the embodiments described above shows specific examples of the present invention, and can be appropriately changed and added within the scope of the inventive concept described in the claims.
