Description

[Detailed Description of the Invention] The present invention relates to an improvement of a blackboard wiping cleaner, and aims to reduce the burden on the user by making it possible to remove the dust bag in a hygienic manner.

In general, blackboard wipe cleaners use a bottomed cylindrical dust bag 16 containing polyurethane 15, etc., as shown in FIG. is the installation.

To take out the dust bag 16, remove the lid 18 covering the top from the cleaner body 19, and open the outer surface 17 a of the bag opening rubber 17.
This is done by pinching the inner surface 17b of the bag mouth rubber 17, but since chalk powder is attached to the inner surface 17b of the bag opening rubber 17, this chalk powder will adhere to the user's fingers, and the user must be sure to remove his/her hands after taking out the dust collection bag. It was a burden because it had to be washed and washed.

The present invention eliminates such conventional drawbacks, and one embodiment thereof will be described below with reference to the drawings.

In the figure, 1 is a cleaner main body, and an electric blower 2 for sucking dust is provided at the rear.

Reference numeral 3 denotes a dust collection bag provided at the front of the cleaner main body 1, which is formed of cloth or the like into a substantially rectangular cylinder shape with a bottom, and an annular bag mouth rubber 4 is integrally attached to the opening of the bag.

3a is a bottomless inner bag made of polyurethane provided inside the dust suction bag 3; 5 is a lid that can be opened and closed to cover the upper part of the cleaner body 1; A suction port 6 for suctioning dust is formed, and a backing plate 7 fixed to the back side of the lid body 5 integrally with the suction port 6 is attached to the dust suction bag 3.
It comes into pressure contact with the bag opening rubber 4 and is air tight.

Reference numeral 8 denotes a slider disposed within the bag opening rubber 4 of the dust suction bag 3, which is formed into a lip shape of rubber or the like as shown in FIG. ,
It has a rod-like shape with both ends touching 4b.

The extension piece 9a of the holder 9 fitted to the lower surface of the slider 8 projects from the suction port 6 to the upper part of the lid 5, and the operator 10 is attached to the skewer end of the slider 8 from the outside as shown by arrow A. It can be slid freely.

Further, this slider 8 is configured such that its upper lip portion 8a is in contact with the back contact plate 7 of the lid body 5.

A leaf spring 11 is interposed between the operator 10 of the slider 8 and the upper surface of the lid 5, and presses the lip 8a of the slider 8 against the contact plate 7.

In the above configuration, the slider 8 is normally positioned at one end of the dust bag 3 by sliding the operator 10 toward one end of the suction port 6, and in this state, a blackboard is placed over the suction port 6 of the lid body 5. Clean the blackboard by placing it on the board and sliding it.

When the dust bag 3 becomes very dirty and needs to be cleaned, first grip the operator 10 and slide it left and right as shown by arrow A.

As a result, the slider 8 slides from side to side inside the bag opening rubber 4 of the dust bag 3 while contacting the inner surfaces of a pair of opposite sides 4a and 4b of the bag opening rubber 4, and the opposite sides 4a and 4b of the bag opening rubber 4,
4b Remove the chalk powder adhering to the inner surface.

Therefore, after opening the lid 5, the user must open the bag opening rubber 4.
If you take out the dust bag 3 by pinching one opposite side, for example, the inner and outer surfaces of 4a, there will be no chalk powder adhering to your fingers.

In addition, in the blackboard wiper of this embodiment, the lip portion 8a of the slider 8 is brought into pressure contact with the back surface of the lid body 5, so that by sliding the slider 8, chalk powder is removed from the bag opening rubber 4 and at the same time, the lip portion 8a of the slider 8 is pressed against the back surface of the lid body. It is also possible to remove chalk powder adhering to the

Therefore, when the lid 5 is opened, an impact is applied to the lid 5, and chalk powder adhering to the back surface of the lid 5 may fall around the cleaner body 1, or the lid 5 may be left unattended with the dust bag 3 forgotten to be set. There is an advantage that the chalk powder on the back of the lid does not fall into the cleaner body 1 due to the impact when the lid is closed, and that it can be handled hygienically at all times.

Further, in this embodiment, since the operator 10 of the slider 8 is made to protrude outside from the suction port 6, there is no need for a special hole in the lid 5 or the cleaner body 1, which has the advantage of simplifying the configuration. be.

As described above, the present invention provides the following excellent effects.

■ Since the inner surface of the opening of the dust bag is cleaned by the slider, it does not get dirty when removing the interior bag, making it extremely hygienic.

II. At the same time, the inner surface of the lid is also cleaned by the slider, so even if the lid is opened to take out the dust bag, chalk powder will not be scattered and the environment will not be degraded.

III. Since the slider is operated using the suction port, the configuration can be simplified and costs can be reduced accordingly.
