Description

[Detailed description of the invention] This invention is designed to prevent the strainer from clogging up the strainer during use, or when powder adheres to the stirring blades, making it impossible to properly sieve the powder. The present invention relates to a convenient powder sifter whose blades can be easily removed and washed with water, and its construction will be described in detail with reference to the accompanying drawings as follows.

A straining net 2 is provided in the lower part of the cylinder 1, a stirring blade 3 is provided on the straining net 2, and a lever 5 provided on the handle 4 on one side of the cylinder 1 is moved against the spring 6. By moving back and forth, the stirring blade 3
In a powder sifter that rotates forward and backward, a fitting groove 7 is formed on the peripheral wall of the cylinder 1 near the falling part 1a, and a straining net 2 having a shaft hole 8 in the center can be attached to and detached from the fitting groove 7. A stirring blade 3 having a square hole 9 in the center is mounted on the strainer net 2 horizontally, and a locking collar 11 is integrally provided at the upper end of a square shaft rod 10 that is aligned with the square hole 9. , a male pin body a having engagement grooves 12 formed in the width direction on both sides facing toward the tip of the square shaft rod 10 is molded in plastic, and a cylindrical body 1 corresponding to this male pin body a is formed.
Press-fit square hole 1 into which square shaft rod 10 is inserted into the center of hole 9
3, and an engagement protrusion 14 with which the engagement groove 12 engages is formed on both opposing surfaces of the press-fit square hole 13, and a connecting rod 1 connected to the lever 5 on one side of the outer periphery of the cylinder body 19.
The female pin receiver b to which the pins 5 are connected is similarly molded from plastic, and the square shaft rod 10 of the male pin body a is fitted into the square hole 9 of the stirring blade 3 in a non-rotating state, and then the shaft hole 8 of the strainer net 2 is inserted. The protruding tip of the square shaft rod 10 is press-fitted into the press-fit square hole 13 of the female pin receiver b, and the engagement groove 12 and the engagement protrusion 14 are engaged to form a male pin body. (a) is removably fitted into the female pin receiver (b).

The engaging groove 12 may be provided on the female pin receiver b side, and the engaging protrusion 14 may be provided on the male pin body a side.

In the figure, 17 is a connecting hole of the connecting rod 15, and 18 is a pivot shaft of the lever 5.

In the conventional powder sifter disclosed in Japanese Utility Model Publication No. 35-28362, the blades are fixed by pins and cannot be removed from the shaft.

The hand mixer disclosed in Japanese Utility Model Application Publication No. 54-119971 also uses a stopper (a type of spring washer) to secure the blades, so it is impossible to easily remove the blades without tools.

The present invention solves this problem and is constructed as described above, so that by holding the locking flange 11 of the male pin body a and pulling it up a little forcefully, the square shaft rod 10 is pushed into the press-fitting angle of the female pin receiver b. It can be pulled out from the hole 13, the stirring blade 3 can be removed, and then the straining net 2 can be taken out from the fitting groove 7.

In this way, the strainer net 2 and the stirring blades 3 can be easily removed, and the strainer net 2 and the stirring blades 3 can be washed with water.

Next, when attaching the strainer net 2 and stirring blades 3, first fit the strainer net 2 into the fitting grooves 7, and then
The stirring blade 3 is placed on this straining net 2, and in this state, the square shaft rod 10 of the male pin body a is inserted into the square hole 9 of the stirring blade 3.
Insert it in a non-rotating state, and then insert it into the shaft hole 8 of the strainer net 2.
When the square shaft rod 10 is press-fitted into the square hole 13 of the cylindrical body 19 of the female pin receiver b, the stirring blade 3 can be attached in a non-rotating state.

In this case, in the press-fit square hole 13, the square shaft rod 10
The engagement groove 12 and the engagement protrusion 14 of the press-fit square hole 13
Since they are engaged, the male pin body a and the female pin receiver b
It is securely fixed and can be used with confidence as it will not come off unless an external force is applied to pull out the male pin body a.

Moreover, since the male pin body a and the female pin receiver b are made of plastic, they can be easily attached and detached.

Therefore, the strainer screen 2 and stirring blade 3 that have been washed with water can be easily attached.

Thus, the present invention provides a convenient powder sifter in which the straining net 2 and stirring blades 3 can be easily removed and attached.

In addition, since the male pin body a and the female pin receiver b are made of plastic, they can be mass-produced by molding, which has excellent practical effects, such as contributing to providing the product at a low price.
