Description

[Detailed Description of the Invention] Industrial Application Field The present invention provides wheat flour that can be easily used at home;
This relates to an electric powder sieve for sifting lumps of cocoa, etc.

Conventional Structure and Problems Conventionally, this type of electric powder sieve has been structured as shown in FIG. That is, in FIG. 4, reference numeral 1 denotes a container for storing powder to be sieved, and a motor case 3 is formed in the center to accommodate and fix a motor 2 with screws 10. A sieve 4 is fixed to the lower part of this motor case 3, and the outside of the container 1 is A handle part 7 is formed to accommodate the battery 5 and the switch 6, and the motor housed in the motor case 3 in the center of the container 1 is connected to the battery housed in the handle part 7 using lead wires 8 and 9. was.

Further, an eccentric weight 12 is fixed to the motor shaft 11, and when power is supplied to the motor 2 by closing the switch 6, the eccentric weight 12 rotates via the motor shaft 11, causing the motor 2 to vibrate. A sieve 4 was vibrated via a motor case 3 to sieve the powder such as wheat flour collected in the container 1.

However, in this configuration, not only the sieve 4 vibrates, but also the motor case 3 vibrates, so the handle part 7 vibrates so much that it is not possible to hold it by hand for a long time. Due to the positioning of the powder, the amount of powder that can be stored in the container and sifted at one time is small, making it inconvenient to use. In addition, in terms of cost, it is necessary to connect the battery 5 inside the handle and the motor 2 in the center of the container 1 using lead wires 8 and 9, so parts such as a cover 13 for the lead wire 8 are required, and the connection is difficult. It also had the disadvantage of being expensive to assemble.

OBJECT OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks, and provides an electric powder sieve that prevents the vibration of the sieve from being transmitted to the handle, increases the capacity of the container, and is inexpensive. With the goal.

Structure of the Invention In order to achieve the above object, the electric powder sieve of the present invention accommodates a switch, a battery, and a motor in the handle, thereby increasing the container storage volume without increasing the external dimensions, and making it easier to assemble lead wires. The sieve is rotatably fixed to a support shaft inside the container, a substantially U-shaped rib is formed on a part of the sieve, an eccentric shaft is fixed to the motor shaft, and this eccentric shaft The handle is fixed to the container so that it fits into the gap between the shaped ribs, and the eccentric shaft rotates when the motor rotates.
The amount of eccentricity of the eccentric shaft becomes the amplitude of the sieve, causing it to vibrate, and since the sieve is fixed to the container in a movable state,
Resonance to the container and handle is extremely small.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

In the figure, reference numeral 21 denotes a substantially cylindrical container, and a support portion 23 for a sieve 24 is formed at the lower opening of the container via several ribs 21a, and a support shaft 30 is fixed to the support portion 23. The sieve 24 is rotatably fitted onto the support shaft 30 and is positioned by a retaining ring 33. Further, a substantially U-shaped rib 28 is formed on a part of the outer periphery of the sieve 24. Reference numeral 27 denotes a handle provided on the outside of the container 21, which accommodates and fixes the switch 26, battery 25, and motor 22 inside, and connects the battery 25 and motor 22 with a positive lead 29, a negative lead 34, and a common lead 35. Further, an eccentric shaft 32 is fixed to a motor shaft 31 of the motor 22, and the eccentric shaft 32 is fitted into a gap between a substantially U-shaped rib 28 formed on a part of the outer periphery of the sieve 24 between the handle 27 and the container 21. It is fixed as possible. Here, the substantially U-shaped rib 28 and the eccentric shaft 32 are fitted to each other through the sieve 24.
The sieve 24 is fitted with a slight gap in the horizontal direction, and with a free gap in the vertical direction of the sieve 24.

Next, the operation of the above configuration will be explained. First, when powder is put into the container 21 and the switch 26 is closed, power is supplied to the motor 22 and the eccentric shaft 32 rotates between the ribs 28 via the motor shaft 31. Therefore, the sieve 24 horizontally vibrates about the support shaft 30 with an amplitude equal to the eccentricity of the eccentric shaft 32, and sieves the powder in the container 21.

In other words, the motor 22 itself does not vibrate, only the sieve 24 vibrates, and the handle portion 2
7 does not vibrate, so it does not cause discomfort to the user even when used for a long time. Also, motor 2
2 is provided inside the handle portion 27 and not inside the container 21, so that the area of the sieve 24 can be increased.

In addition, in this embodiment, the ribs 28 provided on the sieve 24
are provided in the vertical direction, and the sieve 24 is vibrated in the horizontal direction, but the ribs 28 are provided in the horizontal direction, and the sieve 24 is vibrated in the horizontal direction.
It goes without saying that the sieve 24 may be vibrated in the vertical direction.

Effects of the Invention As described above, according to the present invention, since only the sieve vibrates, there is little resonance to the container and handle, and since the motor is located in the handle, powder can be removed without changing the external dimensions of the container. The storage volume can be increased,
Furthermore, since the lead wire can be connected inside the handle, the cost is also reduced.
