Abstract
The invention provides a detachable blackboard eraser dust extraction device which comprises a dust extraction box, a hook, dust extraction sawteeth, a closing mechanism and a baffle. The hook and the rear side of the dust extraction box are integrally formed. An opening is formed at the upper end of the dust extraction box and is closed through the closing mechanism. The dust extraction sawteeth are arranged on one side of the outer side edge of the opening of the dust extraction box. The baffle is connected with the upper ends of the left side and the right side of the dust extraction box in a riveting mode. After the baffle is vertically turned up, the baffle, the closing mechanism and the dust extraction box form a cavity body with a half closed. A dust containing box being capable of being drawn out is located inside the dust extraction box and is outwards drawn through a handle fixed on the dust containing box. According to the detachable blackboard eraser dust extraction device, dust on a blackboard eraser can be conveniently scraped, the dust is not prone to fly upward, and the detachable blackboard eraser dust extraction device is economical and practical.
Description
Technical field
The present invention relates to a kind of detachable blackboard and brush the dirt device.
Background technology
Present blackboard brush is simple in structure, can stay a lot of dust above use is rear, is generally to scrape dust in the ledge for chalk on blackboard below blackboard, but easily causes dust to fly upward everywhere, contaminated air.CN101734062A discloses a kind of dust absorption blackboard eraser, comprise blackboard eraser body, dust absorbing case and blackboard eraser hairbrush, it is equipped with a Small-sized suction cleaner and a muffler on the blackboard eraser body, a circular aperture is arranged on the dust absorbing case, reduces flying upward of dust by Small-sized suction cleaner.But this design cost is higher, is not suitable for using at school's spread.
Summary of the invention
The object of the present invention is to provide a kind of detachable blackboard to brush the dirt device, the defects that exists to overcome prior art.
In order to achieve the above object, the present invention adopts following technical scheme to realize:
A kind of detachable blackboard brushes the dirt device, comprise dedusting box, hook, dedusting sawtooth, close mechanism and baffle plate, described hook and described dedusting box rear side are integrally formed, described dedusting box upper end open, seal by close mechanism, described dedusting sawtooth is arranged on outer edge one side of described dedusting box opening, described baffle plate is riveted on respectively upper end, the dedusting box left and right sides, become a semi-enclosed cavity after vertically digging with the dedusting box-like with close mechanism, the drawing out type cartridge is positioned at the dedusting box, outwards extracts by the handle that is fixed on cartridge.
The present invention can be easily scrapes off the dust of blackboard brush, and dust is difficult for flying upward, and economical and practical.
Description of drawings
Fig. 1 is the structural representation that detachable blackboard of the present invention brushes the dirt device.
The specific embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to describe technical scheme of the present invention in detail.
as shown in Figure 1, a kind of detachable blackboard brushes the dirt device, comprise dedusting box 1, hook 2, dedusting sawtooth 3, close mechanism 4 and baffle plate 5, described hook 2 is integrally formed with described dedusting box 1 rear side, described dedusting box 1 upper end open, by close mechanism 4 sealings, described dedusting sawtooth 3 is arranged on outer edge one side of described dedusting box 1 opening, described baffle plate 5 is riveted on respectively dedusting box 1 upper end, the left and right sides, vertically dig rear and close mechanism 4 and dedusting box 1 formation one semi-enclosed cavity, drawing out type cartridge (6) is positioned at dedusting box 1, outwards extract by the handle 7 that is fixed on cartridge 6.
At ordinary times detachable blackboard of the present invention is brushed on the ledge for chalk on blackboard that the dirt device hangs over blackboard below, during use, close mechanism 4 is opened, the bristle of blackboard brush is placed in the semi-enclosed cavity that is formed by baffle plate 5 and close mechanism 4 and dedusting box 1, move down close mechanism 4, bristle will adhere to superincumbent dust and scrape and drop in dedusting box 1 through sawtooth 3, constantly moves until close close mechanism 4, and the taking-up blackboard brush.After the dust accumulation is more, but pull handle (7) extracts dedusting box (1) and cleans.All the time in above-mentioned cavity, dust can outwards not fly upward due to the bristle of blackboard brush, and the protection classroom environment is clean and tidy.
