Abstract
The utility model discloses a mechanism for removing chalk dust on blackboard erasers. The mechanism comprises a flat box with a movable cover, and a partition arranged in the middle of the box is provided with a plurality of holes and divides the box into two chambers including an eraser chamber for holding a blackboard eraser above the partition and a dust collecting chamber for storing chalk dust below the partition. The mechanism for removing chalk dust on blackboard erasers is simple in structure and convenient for use, and effectively prevents dust flying when using the blackboard erasers to remove chalk dust.
Description
Technical field
The utility model relates to a kind of chalk dust mechanism that goes, the mechanism of chalk dust on especially a kind of simple clean free of contamination removal blackboard eraser.
Background technology
As the today of also not realizing complete dustless classroom, chalk and blackboard are still in occupation of the leading position of daily teaching.The combination of chalk and blackboard wants cheap and convenient more than electric whiteboard system, yet the dust pollution question that the combination of chalk and blackboard brings all is the defective place that can not be ignored all the time.Therefore invent, improved various dustless, dustproof chalks and blackboard eraser be also too numerous to mention.People have truly had very much progress in the dustproof design of the dustless improvement of chalk and blackboard eraser.Yet the program of having wiped behind the blackboard for blackboard eraser but rarely has improvement.Total institute is known, after blackboard eraser has been wiped one section chalk dust, the chalk dust of blackboard eraser need be removed and could continue to use, and this is because the amount of adhering to dust of blackboard eraser is restricted.Present most teacher wipes the blackboard that is over to take the corridor then and go to knock out.It at this time is again the dust of soaring for a moment.Though we reduce dust painstakingly in chalk and blackboard eraser wiping process, on removing, the dust of removing blackboard eraser falls short of success for lack of final effort.
The utility model content
The purpose of this utility model is for a kind of mechanism of removing chalk dust on the blackboard eraser is provided, to solve the problems referred to above of prior art.
The purpose of this utility model can be achieved through the following technical solutions.
A kind of mechanism of removing chalk dust on the blackboard eraser comprises the flat case of the movable lid of a band, and the centre position in the described box body is provided with dividing plate, and dividing plate is provided with plurality of holes; Dividing plate is separated into two cavitys with box body: the blackboard eraser chamber that blackboard eraser is placed in the dividing plate top, the dust collection chamber that chalk dust is stored in the dividing plate below.
Described blackboard eraser chamber length and width are tall and big in the length and width height of blackboard eraser.
Described dividing plate is an active clapboard, and is as at box body madial wall fluting, fixing in the dividing plate insertion groove.
The utility model makes chalk dust drop by vibrating in the blackboard eraser chamber, and is collected into dust collection chamber by the hole on the dividing plate, after a period of time, dividing plate can be taken out, and the water flushing is in order to reusing.
The mechanism of chalk dust on the removal blackboard eraser that designs by the utility model, simple in structure, the convenient use efficiently solves the blackboard eraser problem that dust flies upward when removing chalk dust.
Description of drawings
Fig. 1 is a design feature of the present utility model;
Among the figure: 1, box body 2, dividing plate 3, hole 4, blackboard eraser chamber
5, dust collection chamber 6, lid.
The specific embodiment
Further set forth design feature of the present utility model below in conjunction with accompanying drawing and specific embodiment.
The mechanism of chalk dust on the removal blackboard eraser as shown in Figure 1 comprises the flat case 1 of the movable lid 6 of a band, and the centre position in the described box body 1 is provided with dividing plate 2, and dividing plate 2 is provided with plurality of holes 3; Dividing plate 2 is separated into two cavitys with box body 1: the blackboard eraser chamber 4 of blackboard eraser is placed in dividing plate 2 tops, and the dust collection chamber 5 of chalk dust is stored in dividing plate 2 belows.
During use, open the lid, blackboard eraser is put into blackboard eraser chamber 4, slightly firmly rock several times then, slightly wait a moment, lid 6 is opened, take out blackboard eraser and get final product.
A period of time can open lid 6 after using, and dividing plate 2 is taken out, and the water flushing is dried promptly to can be used as and used next time.
