Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a citrus juice extractor for commercial use.

BACKGROUND TECHNOLOGY Conventionally, the squeeze cone mounting portion of this type of citrus juice squeezer is shown in, for example, Japanese Patent Publication No. 44-6605, and specifically has a structure as shown in FIG. 5. That is, the attachment part of the squeezing cone 21 is provided with a ball 24 biased by a spring 23 on a part of the rotating shaft 22 in a state that it does not come off, and a groove 21b is provided in the metal insert 21a of the squeezing cone 1 corresponding to the position of the ball 24. ,
Positioning was performed by fitting the ball 24 into the groove 21b. Furthermore, the rotating shaft 22 and the metal insert 21b each have serrations to prevent rotation.

Problems to be Solved by the Invention However, with the mounting configuration of the squeezing cone 21 having such a structure, it is weak against force in the pulling direction and does not hold the fruit well. There was a problem in that the cone 21 came off and collided with the fruit holder, resulting in damage.

Means for Solving the Problems The technical means of the present invention for solving the above problems is to provide a slide fitting on the back side of the squeezing cone and an annular groove on the rotating shaft.

Function: With this technical means, the slide fitting fits into the annular groove and exhibits the effect of preventing the squeezing cone from coming off.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings. In FIGS. 1 to 4, 9 is a main body, which has an electric motor and a speed reduction mechanism inside. The rotation of the electric motor is transmitted in a reduced manner to a pair of removable squeezing cones 1 and a pair of holders 5 via a cam mechanism 10. The squeezing cone 1 slidably holds a slide fitting 6 having a hole larger than the shaft diameter of the rotary shaft 2 on the back side of the central portion thereof via a screw 7. Further, the slide fitting 6 is biased in one direction by a leaf spring 8. The rotating shaft 2 has an annular groove 2a.
A cutter 11 is removably provided on the upper part of the main body 9, and is located substantially on the central plane of the pair of holders 5 and divides the fruit into two equal parts. Further, 12 is a transparent cover that can be attached to and detached from the main body 9, which prevents fruit juice from scattering and forms a fruit inlet 12a. 13 is a fruit juice receptor, which serves to filter and store the squeezed fruit juice. Further, 14 is a power switch.

Next, the operation of the configuration of this embodiment will be explained. When the power switch 14 is turned on, the squeezing cone 1 and the holder 5 begin to rotate. When the whole fruit is put in through the input port 12a, a pair of holders 5 rotate.
The fruit is pushed into the cutter 11, and the fruit is divided into two equal parts. The cut fruit is led to and held by the holder 5 which makes an oscillating motion. Rotating holder 5
The cone 1 is located on the rotating locus and swings its head so as to press the fruit held against the rotating squeezing cone 1 to squeeze the fruit juice. Thereafter, the fruit continues to rotate while holding the outer skin of the fruit, and when the holder 5 becomes horizontal, the outer skin is removed and dropped. The removed outer skin passes through the through hole 9a of the main body 9 and is stored in a trash can placed at the bottom of the main body 9.

When putting on the squeezing cone 1, when the squeezing cone 1 is pressed against the rotating shaft 2, the slide fitting 6 moves against the leaf spring 8, and the rotating shaft 2 and the metal insert 1 are moved.
The serrations in a fit together. Insert more
When the slide fitting 6 comes to the position of the annular groove 2a, it gets stuck under the force of the leaf spring 8, and the squeezing cone 1 is positioned. To remove the squeezing cone 1, press the protrusion 6a of the slide fitting 6 with your finger, remove the slide fitting 6 from the annular groove 2a, and pull it out.

Effects of the invention This invention provides a slide fitting on the back side of the squeezing cone and an annular groove on the rotating shaft.
It has the effect that the squeezing cone can be held more reliably and can be easily attached and detached.
