[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pulverizer for cutting dry matter, vegetables and the like with a cutter rotated by the power of a motor to produce powder, juice and the like.

[0002]

2. Description of the Related Art The applicant of the present invention detachably screwes a lower part of a bottle having an open lower surface to a bottle support, and attaches the bottle and the bottle support to a rotating shaft penetrating a bottom wall of the bottle support. We have already proposed a small pulverizer that cuts dry matter and vegetables stored in a closed chamber by forming a closed chamber that houses the cutter, and rotating the rotating shaft with the power of a motor to produce powder and juice. . The powder and juice made by this crusher can be taken out by turning the whole crusher upside down and placing it in the bottle, then removing the bottle from the bottle support as it is .

[0003] In this type of crusher, a ring-shaped rubber packing is interposed between the bottle and the bottle support in order to increase the degree of sealing of the closed chamber. This packing is required to be detachable for cleaning, and it is necessary to prevent the packing from dropping when opening and closing the opening of the bottle by the bottle support, such as the above-described removal of the produced powder or the like.

The bottom wall of the bottle support is provided with a circular raised portion and a ring-shaped sealing groove surrounding the raised portion. The packing is removably housed in the sealing groove, and is provided on the bottle support. The packing was sandwiched between the lower end surface of the screwed bottle and the bottom surface of the seal groove. The packing is fitted by fitting the entire inner peripheral surface thereof to the entire outer peripheral surface of the raised portion, thereby performing positioning of the packing with respect to the bottle support and holding of the packing when the packing is turned upside down. I have.

[0005]

However, it is known that rubber packing has a large variation in molding dimensions, and that strict control of the dimensional accuracy makes production difficult. For this reason, there is a problem that the packing is difficult to be adapted to the size of the raised portion of the bottom wall due to the variation in the dimensions. That is, if the inner diameter is smaller than the outer diameter of the raised portion due to the variation in the molding dimensions of the packing, the packing easily falls when opening and closing the bottle opening with the bottle support, such as taking out crushed powder or the like. This causes the inconvenience. Further, when the inner diameter of the packing is slightly smaller than the outer diameter of the raised portion, there arises a problem that the packing is attached and detached and supported.

The object of the present invention is to make it easy to attach and detach the packing to and from the bottom wall of the bottle support and to turn the bottle upside down regardless of the dimensional variation of the rubber packing sandwiched between the bottle and the bottle support. Thus, it is an object of the present invention to obtain a crusher capable of preventing the packing from dropping when the opening is opened and closed by the bottle support.

[0007]

According to the present invention, a ring-shaped rubber packing is sandwiched between a bottle having an open lower surface and a bottle support to which the bottle is removably screwed.
The cutting is performed in a closed chamber formed by a bottle and a bottle support, and the powder or juice obtained by the cutting is applied to a crusher that inverts the bottle upside down and removes the bottle together with the bottle to achieve the above object. In order to achieve this, a packing engaging portion is provided at several locations around the raised portion of the bottom wall so as to be in contact with the inner periphery of the packing, and the radius from the tip of the packing engaging portion to the center of the bottom wall is free. And a radius of a portion of the raised portion located between adjacent packing engaging portions is made smaller than a radius of the center hole.

[0008]

According to the above arrangement, the relationship between the radius of the center hole of the rubber packing, the radius of the packing engaging portion of the raised portion of the bottle support bottom wall, and the radius of the portion between the adjacent packing engaging portions is provided. The packing is fitted to the outer circumference of the raised portion while slightly expanding outward by engaging only a few portions of the inner circumference with the packing engaging portion, and is housed and mounted in the seal groove. For this reason, variations in the dimensions of the inner periphery of the packing can be absorbed. As described above, since the contact between the raised portion and the packing is limited to several places and is small, the frictional resistance when attaching and detaching the packing to and from the raised portion can be reduced. In addition, since the packing is engaged with the packing engagement portions at several places as described above, the packing does not rattle and fit into the raised portion.

Thereby, a cutter 15 is provided between the bottle support 5 and the bottle 19.
A closed chamber A for accommodating is provided. The cutter 15 is arranged at the lower end of the closed chamber A, and the closed end face 19a allows the bottle 19 to be stably placed upside down.

In the seal groove 11, a ring-shaped rubber packing 20 having a center hole 20a fitted into the raised portion 10 is detachably accommodated. This packing 20 is used when the bottle 19 is attached to the bottle support 5.
It is sandwiched between the lower end surface of the bottle 19 and the groove bottom surface 11a of the seal groove 11, and is used to increase the degree of sealing of the closed chamber A.

A plurality of ribs 21 are formed at several locations around the raised portion 10 of the bottom wall 8 so as to extend in the vertical direction as seal engagement portions whose tips are in contact with the inner periphery of the packing 20. FIG. 4 shows a dimensional relationship between the ribs 21 and the respective portions of the bottom wall 8. That is, the radius B from the tip of the rib 21 to the center of the bottom wall 8 is determined by the packing 2 in the free state.
The radius C of the portion located between the adjacent ribs 21 in the raised portion 10 is smaller than the radius B of the center hole 20a, and the radius D of the portion is smaller than the radius C of the center hole 20a. Is smaller than the radius F of the inner circumference of the peripheral wall 7.

When using the crusher having the above-described structure, first, the packing 20 is fitted into the raised portion 10 of the bottom wall 8 of the bottle support 5, and the packing 20 is stored in the seal groove 11. Next, after the object to be crushed is stored in the bottle 19 which is turned upside down, the bottle support 5 with the packing 20 attached thereto is put on the bottle 19, and the female screw 7a and the male screw portion 19b of each other are screwed. Combine. Thereafter, the bottle support 5 and the bottle 19 are turned over together, and the bottle support 5 is fitted on the cylindrical portion 3 of the main body 1 and mounted on the pedestal 1a, thereby obtaining the state shown in FIG. In this state, the motor 2 is operated and the cutter 15 is rotated to cut the material to be crushed in the closed chamber A to produce powder, juice and the like.

In order to take out the powder or juice from the bottle 19 after use, the bottle support 5 is removed from the main body 1 and the support 5 and the bottle 19 are turned upside down. By rotating the bottle support 5, the bottle support 5 is removed from the bottle 19. Thereby, the powder and the like in the bottle 19 can be taken out.

Cleaning after use is performed not only on the bottle 19 and the bottle support 5 disassembled as described above, but also by removing the packing 20 from the bottle support 5.
