Description

[Detailed description of the invention] This invention relates to a flour mill for sprinkling, which can automatically grind dry foods such as dried sardines and seaweed for sprinkling, and is mainly suitable for home use.

Conventionally, in the above-mentioned sprinkling flour mill, the grinding blade rotates immediately upon turning on the power switch, regardless of whether or not the cap that closes the upper opening of the grinding chamber is attached or removed. That is, once the power switch is turned on, the crushing blade continues to rotate unless it is turned off. Therefore, if you leave the cap without turning off the power switch, there is a risk of unexpected injury from the rotation of the crushing blade.

The purpose of this invention is to provide a sprinkling flour mill that eliminates the above-mentioned drawbacks by allowing the grinding blades to stop rotating when the cap is removed with the power switch turned on.

Hereinafter, embodiments of this invention will be described based on the drawings. In FIG. 1, 1 is a case, and a motor 3 is supported on the lower surface of an upper wall portion 2 of the case. A rotating shaft 4 of the motor 3 projects above the upper wall portion 2, and a drive shaft 5 is fixed to the projecting portion. 6 is the battery stored below the motor 3, 7 is the lower case 1
This is an operation knob provided on the front of the , and this operation knob 7 turns on the power switch 8,
The battery 6 is connected to the motor 3.

Reference numeral 9 denotes an upper case detachably supported by the lower case 1, and the interior of the upper case 9 is configured as a grinding chamber 10 with an upper opening. 11 is a blade holder in which a crushing blade 12 is provided in the shape of a wing. The blade holder 11 has a connecting cylinder portion 13 formed on the lower surface.
It is rotatably and vertically movably provided at the center of the bottom portion 14 of the crushing chamber 10, and is supported by the bottom portion 14 of the crushing chamber 10 so as to be vertically movable via a spring member 15 fitted onto the connecting cylinder portion 13. Reference numeral 16 denotes an operation rod protruding from the upper center of the blade holder 11;
A cap 7 is removably fitted into the upper opening of the crushing chamber 10. A protrusion 18 is formed at the center of the lower surface of the cap 17, and the protrusion 18 is connected to the upper end of the operating rod 16. ing. That is,
The protrusion 18 of the cap 17 comes into contact with the operating rod 16 and pushes the blade holder 1 against the spring force of the spring member 15.
1 is held in a downwardly biased position, and the connecting cylinder portion 13 is fitted and engaged with the drive shaft 5 so as to be integrally rotatable therewith. The protrusion 18 and the operating rod 16 are in spherical contact with each other at one point in order to prevent the operating rod 16 from steadying and to reduce rotational resistance. Reference numeral 19 denotes a stopper formed at the lower end of the connecting cylinder portion 13, and as shown in FIG. prevent. As shown in FIG. 2, in the upwardly biased position of the blade holder 11, the connecting cylinder portion 13 separates from the drive shaft 5.

In the above configuration, the sprinkling material is placed in the crushing chamber 10.
When the powder is thrown into the pulverizer and pulverized, the upper opening of the pulverizing chamber 10 is closed by the cap 17. In FIG. 1, the connecting cylinder portion 13 is connected to the drive shaft 5 as the cap 17 is attached. This allows operation knob 7
When power switch 8 is turned on, motor 3
is driven, and the power is transmitted from the drive shaft 5 to the connecting cylinder portion 1.
3, and the blade holder 11 and the crushing blade 12 rotate. Furthermore, if the cap 17 is removed while the power switch 8 is turned on, the blade holder 11 is pushed up by the spring member 15, and the connecting cylinder 13 is removed from the drive shaft 5, as shown in FIG. . That is, the power transmission from the motor 3 to the blade holder 11 is cut off, and the rotation of the blade holder 11 is stopped.

Note that the operating rod 16 can be provided on the cap 17 side.

As described above, according to this invention, even if the power switch is in the ON state, the rotation of the blade holder, that is, the crushing blade, stops when the cap is removed.
Even if you accidentally put your fingertips into the crushing chamber, there is no risk of injury from the crushing blade.
