Description

[Detailed description of the invention] Industrial applications The present invention is 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, 1 is a container for storing powder to be sieved, and a motor case 3 is formed in the center of the container to house and fix a motor 2 with a screw 1o.
A sieve 4 is fixed at the bottom, and a battery 5 and a switch 6 are placed outside the container 1.
The motor housed in the motor case 3 at the center of the container 1 and the battery housed in the handle part T were connected by lead wires 8 and 9.

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, and the motor 2 is activated. The sieve 4 vibrates via the motor case 3, and the powder such as wheat flour collected in the container 1 is sieved.

However, in this configuration, not only the sieve 4 vibrates, but the motor case 3 also vibrates, so the vibration of the light hand part is large, and it is not only impossible to hold it with the handle for a long time, but also the center part of the container 1 Due to the location of the motor, the amount of powder that could be stored in the container and sifted at one time was small, making it inconvenient to use. Also, in terms of cost, it is necessary to connect the battery 6 inside the handle and the motor 2 in the center of the container 1 using lead wires 8 and 9.
This method has disadvantages in that it does not require third grade parts, and the cost of assembling the connections is high.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks, and aims to provide an electric duster which prevents the vibration of the sieve from being transmitted to the handle, increases the capacity of the container, and is inexpensive. purpose.

Structure of the Invention In order to achieve the above object, the electric duster of the present invention accommodates a switch luminaire and a motor in the handle, thereby increasing the container storage volume without increasing the outer dimensions of the container, and making it easier to assemble lead wires. To make it simple, 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 is attached to the U-shaped The handle is fixed to the container so that it fits into the gap between the ribs.The eccentric shaft rotates as the motor rotates, and the eccentricity of the eccentric shaft becomes the amplitude of the sieve, causing it to vibrate, so the sieve can be moved into the container. Container because it is stuck in the state.

Resonance to the carrier is extremely small.

DESCRIPTION OF EMBODIMENTS Hereinafter, an embodiment of the present invention will be described based on FIGS. 1 to 3. In the figures, 21 is a substantially cylindrical container, and several supporting parts 23 of sieves 24 are installed in the lower opening of the container. formed through the rib 21a of
A support shaft 30 is fixed to the support portion 23. The sieve 24 is rotatably fitted onto the support shaft 3o and is positioned by a retaining ring 33. A substantially U-shaped rib 28 is formed on a part of the outer periphery of the single sieve 24. 27 is a handle provided on the outside of the container 21, and a switch 26. Battery 25. The motor 22 is housed and fixed inside, and the positive lead 29. Negative lead 34. A common lead 35 connects the stain pond 25 and the motor 22. Further, an eccentric shaft 32 is fixed to a motor shaft 31 of the motor 22, and a carrier 27 and a container 21 are connected to each other.
is a substantially U-shaped rib 2 formed on a part of the outer periphery of the sieve 24.
The eccentric shaft 32 is completely fixed so as to fit into the gap 8.

Here, the substantially U-shaped rib 28 and the eccentric shaft 32 are fitted with a slight gap in the horizontal direction of the sieve 24, and with a free gap in the vertical direction of the sieve 24.

Next, the operation of the above structure will be explained. 0 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 is moved through the motor shaft 31 to the rib 2.
Rotate between 8. Therefore, the sieve 24 horizontally vibrates about the support shaft 30 with an amplitude corresponding 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 and the sieve 24
Since only the handle part 27 vibrates and the handle part 27 does not vibrate, the user does not feel uncomfortable even if it is used for a long time. Further, since the motor 22 is provided inside the handle 27 and not inside the container 21, the area of the sieve 24 can be increased.In this embodiment, the ribs 28 provided on the sieve 24 are arranged in the vertical direction. Although the sieve 24 was vibrated in the horizontal direction, the ribs 28 were provided in the horizontal direction and the sieve 24 was vibrated in the horizontal direction.
It goes without saying that 4 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 handle of the container 9, and since the motor is located in the handle, the powder can be removed without changing the external dimensions of the container. The storage volume can be increased, and the cost can be reduced because the lead wire can be connected inside the handle.
