Chinese patent literature is also disclosed an entitled environment-friendly dust-proof eraser, the patent of invention of publication number CN101417575, its bag Including upper shell and lower house, the end face indent of upper shell is formed with the receiving space accommodating water-absorbing sponge, and end face is coated with wiping Cloth, the outward flange extension of the end face of upper shell is configured to connecting plate, and the base plate accommodating space is provided with inlet opening, and inlet opening sets Being equipped with water fender, the back side of base plate is formed with connecting plate, and lower house includes end face, and the outward flange of end face is provided with buckle, button Plate is fastened on aforementioned connecting plate and is configured to close dust collecting space, is additionally integrally formed with buckle in end face, and buckle is fastened on base plate Connecting plate on and be configured to close water storage space, close in water storage space and be provided with fore-set, fore-set one end is arc-shaped and props up Water fender, the other end of fore-set extends to the end face of lower house and outward and is formed with button, is provided with roller between wiper and water-absorbing sponge, The two ends of roller are stretched out outside upper shell, and upper shell is provided with the track accommodating roller；The side plate respective roller position in described receiving space sets There is dust inlet.

Above-mentioned existing patented technology, although optimize the function of blackboard eraser, but be required for operator's hand-held blackboard eraser main body, The scope of its wiping is limited by operator's arm length.

Utility model content

This utility model provides a kind of novel blackboard eraser suit, solves what blackboard eraser wiping scope was limited by arm length Technical problem, improves blackboard-cleaning efficiency and effect.

In order to solve above-mentioned technical problem, this utility model adopts the following technical scheme that

A kind of novel blackboard eraser suit, including framework, big blackboard eraser and little blackboard eraser, described framework include the first crossbearer, second Crossbearer and longitudinally connected frame, the first crossbearer and the second crossbearer are separately fixed at two ends of longitudinally connected frame, described big blackboard eraser Including handle and the first rub body, head is arranged on handle end, and described little blackboard eraser includes wiping torr and the second rub body, described longitudinal direction Arranging support filler ring on link, the handle device of big blackboard eraser is arranged in support filler ring, and described second crossbearer is installed pallet, little Blackboard eraser entirety is positioned on pallet.

Based on such scheme, this utility model also does and improves as follows:

Described first rub body includes the spongy body being arranged on its face, and this spongy body arranges longitudinally spaced being arranged in order Some sponge peaks and sponge paddy.

Described handle is provided with flow-guiding structure, and this flow-guiding structure includes the water conservancy diversion received in handle circumference is the most uniform Face, and the gap that guide face bottom is formed, circumferentially disposed gap, gap outer wall, arrange through leading in the handle of bottom, gap Circulation road, this flow-guiding channel Single port communication gap, another port is opened on handle, at its lower end face.

The lower surface of described handle arranges fluid collection device.

On described pallet, skid resistant course is set.

The length of described handle is 50-100 centimetre.

Compared to the prior art, this utility model produces and provides the benefit that:

1. one basic framework of this utility model design, this framework is fixed on blackboard by the first crossbearer and the second crossbearer Side up and down on, the longitudinally connected left and right either side edge being placed on blackboard, longitudinally connected frame arranges support filler ring, this Sample is possible to prevent the big blackboard eraser of band handle in this utility model, and the handle arrangement of big blackboard eraser is the extension to operator's arm, expands The big scope of traditional blackboard wiping, anyone can be easily with the big any position of blackboard eraser blackboard wiping, simultaneously at the second horizontal stroke Pallet is set on frame, places the little blackboard eraser in this utility model, the compatible motility of little blackboard eraser.

2. some sponge peaks at longitudinally disposed interval and sponge paddy on the first rub body, when blackboard wiping, can be by portion Break flour is divided to be placed in sponge paddy, it is simple to rinse.

3., in wiping process, moisture stretches out from sponge and flows downward along handle, and the correct position at handle arranges water conservancy diversion Structure, this flow-guiding structure design guide face, guide face bottom arranges the interim gap storing moisture again, arranges water conservancy diversion and lead in gap Road, the other end opening of flow-guiding channel goes directly handle bottom surface, thus can be flowed out from handle bottom surface by direct for moisture water conservancy diversion, then Fluid collection device is fixed in handle bottom surface, it is achieved the effect of clean catch.
