Abstract

The utility model relates to a electric dust collecting blackboard eraser, comprising a casing equipped with a crosswise baffle and a plurality of ventilators, a handle and a cleaning cotton, wherein the casing is equipped with a plurality of breathers on the top wall, the baffles and the base wall. A ventilating sponge is stick on the inner surface of the top wall which is folded connected with the case. Once massive chalk dust is diffusing when cleaning the blackboard, the ventilators switch is turned on to make the blade wheel rotating, then the outer air is absorbed into the casing via the base wall. As the current includes chalk dust, the dust willbe absorbed by the sponge, realizing absorbing function. The utility model has the advantages of rational structure, wide application and powerful function, elegant appearance, high effect and safety. Further the utility model can absorb chalk dust quickly by ventilator thereby protecting the health of the operators effectively.

Description

Electric dust absorption blackboard eraser

Technical field the utility model relates to a kind of realia, especially a kind of electric dust absorption blackboard eraser that absorbs chalk dust.

Technical background is present, blackboard eraser is most important blackboard burnisher, but present blackboard eraser causes the phenomenon of " stirring up a cloud of dust " in use easily, is seriously influencing the healthy of teachers and students, with regard to its reason, exactly because present blackboard eraser does not have the function that absorbs dust.In order effectively to solve this class problem, we provide a kind of new blackboard that can absorb chalk dust to wipe.

The summary of the invention the purpose of this utility model provides a kind of electric dust absorption blackboard eraser, is used to solve the problem that ordinary blackboard eraser can't absorb chalk dust.

For achieving the above object, the utility model electric dust absorption blackboard eraser, many cleaning cottons that comprise the cube shell, are installed in the handle of upper surface of outer cover and stick on the shell bottom plate surface, laterally be provided with dividing plate in the enclosure, box body is divided into two parts up and down, at the motor of box body upper space installation ventilating fan, the impeller of ventilating fan then is installed in the box body lower space; All offer a plurality of air-vents in the gap between per two cleaning cottons on top board, dividing plate and the base plate of shell; Paste the ventilative sponge of one deck at the inner surface of sheath top plate, and the top board of shell is that folding is connected with box body.

After adopting said structure, ventilating fan be installed in box body inside after battery, switch are connected, after the user used the cleaning cotton blackboard wiping, the chalk dust on blackboard surface will drop, and formed dust from flying, at this moment the user only needs the gauge tap of closed row fan, make its impeller rotation suck a large amount of air from shell bottom plate, therefore also can absorb dust, these dust are by finally being absorbed by the ventilative sponge at sheath top plate place behind the dividing plate, air then can be discharged from sponge, forms gas circulation.

The utility model has the advantages that: rational in infrastructure, be widely used, powerful, elegant in appearance, efficient quick, safe and sanitary, also can be by the effect fast Absorption chalk dust of ventilating fan, can protect effectively that the user's is healthy.

Description of drawings Fig. 1 is the overall structure schematic diagram of the utility model electric dust absorption blackboard eraser.

The specific embodiment as shown in Figure 1, the utility model electric dust absorption blackboard eraser, many the cleaning cottons 3 that comprise cube shell 1, are installed in the handle 2 of shell 1 upper surface and stick on shell 1 backplate surface, in shell 1, laterally be provided with dividing plate 4, box body is divided into two parts up and down, at the motor of box body upper space installation ventilating fan 5, the impeller of ventilating fan 5 then is installed in the box body lower space; All offer a plurality of air-vents 6 in the gap between per two cleaning cottons 3 on top board, dividing plate 4 and the base plate of shell 1; Paste the ventilative sponge 7 of one deck at the inner surface of shell 1 top board, and the top board of shell 1 is that folding is connected with box body.Wherein, ventilating fan 5 is connected in series with battery, gauge tap, and gauge tap is arranged on shell 1 upper surface, is convenient to user's operation control; For strengthen dust suction can, in box body, can increase or reduce the quantity of ventilating fan according to actual needs.When using, the user holds handle 2 usefulness cleaning cottons 3 blackboard wipings, if producing a large amount of chalk dusts during blackboard wiping flies upward, but the gauge tap of user's closed row fan 3, make the impeller of ventilating fan 5 begin rotation, attract outer gas stream to enter box body inside from shell 1 base plate, these air fail to be convened for lack of a quorum and carry a large amount of chalk dusts and enter box body, air stream sees through the dust suction sponge 7 of dividing plate 4 and top board inner surface and finally discharges from the air-vent of top board, the chalk dust that is mixed in the air stream then can be by absorption that dust suction sponge 7 stops in exhaust process, therefore do not have the dust discharge, thereby reached the purpose of dust suction; If the chalk dust in the box body is too much, the user also can open top board taking-up dust suction sponge 7 and clean, and can be recycled.
