Abstract

The invention provides a convenient-to-dismount dustproof blackboard eraser. The dustproof blackboard eraser comprises an eraser body, an eraser housing and a handle, wherein the handle is connected with the upper part of the eraser housing; a dust suction channel formed in the handle is communicated with an inner cavity of the eraser housing; a dust suction device communicated with the dust suction channel is arranged on the handle; the lower half part of the eraser housing is embedded into a concave cavity of the eraser body; the concave cavity of the eraser body is internally provided with a dust collecting chamber; clamping feet arranged at the lower end of the eraser housing are buckled with clamping grooves in the eraser body; and the clamping feet are connected with a button on the handle through tension springs. After much dust is accumulated, the button for dismounting is pressed, and the eraser body is separated and replaced by a new eraser body. After class, the eraser body in which the dust is accumulated is collected and cleaned by educational administration logistical personnel in a unified manner, so that an environment in a classroom is prevented from being polluted.

Description

A kind of dustproof blackboard eraser for convenience detach
Technical field
The invention belongs to teaching aid field, especially relates to a kind of dustproof blackboard eraser for convenience detach.
Background technology
At present, blackboard and chalk remain the teaching aid often used in teaching process.After blackboard writes word, can drop when erasing the board with common blackboard eraser many chalk powders.Chalk powder bulk deposition can affect the environment in classroom, once be subject to wind etc., also can dust from flying, and easily human body is damaged.The cleaning layer adsorption capacity of conventional blackboard eraser is limited, dust gather too much in, can only, by beaing, dust be fallen on the ground.This process causes again new pollution.Very unfavorable to the person.
Innovation and creation content
In view of this, the invention is intended to propose a kind of dustproof blackboard eraser for convenience detach, gathers too much, cause the problem of environmental pollution during cleaning to solve dust on blackboard eraser.
For achieving the above object, the technical scheme of the invention is achieved in that
A dustproof blackboard eraser for convenience detach, comprises rub body, wipes shell and handle; Described handle is connected to wipes shell top, and the dust absorption passage arranged in handle and wiping shell inner space; Described handle is provided with the dust exhaust apparatus being communicated with dust absorption passage; Described wiping shell the latter half embeds the cavity of rub body; Also dust storage chamber is provided with in the cavity of described rub body; Draw-in groove buckle on the card base that described wiping shell lower end is arranged and rub body; Described card base is connected with the button on handle by extension spring.
Further, described rub body comprises the wiping layer of wiping board and the setting of wiping board bottom.
Further, described wiping layer is nylon bristle or layer of cloth with holes.
Further, described dust exhaust apparatus comprises motor, fan and power supply.
Further, described handle is provided with anti-slip veins.
Further, described handle is inverse u shape structure.
Relative to prior art, the dustproof blackboard eraser a kind of for convenience detach described in the invention has following advantage:
When dust accumulation is more, dismounting button can be pressed, rub body is departed from, the rub body more renewed, wait and gathered by the unified collection cleaning of educational administration rear service personnel the rub body having dust after class, clear up, avoid and pollute classroom environment.
Accompanying drawing explanation
The accompanying drawing of the part of formation the invention is used to provide the further understanding to the invention, and the schematic description and description of the invention, for explaining the invention, does not form the improper restriction to the invention.In the accompanying drawings:
Fig. 1 is the structural representation of the invention.
Description of reference numerals:
1-rub body, 2-wipes shell, 3-handle, 4-dust storage chamber, 5-dust exhaust apparatus, 6-card base, 7-button, 8-wiping board, and 9-wipes layer; 10-draw-in groove; 11-anti-slip veins.
Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the invention and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the invention in detail in conjunction with the embodiments.
A dustproof blackboard eraser for convenience detach, comprises rub body 1, wipes shell 2 and handle 3; Described handle 3 is connected to wipes shell 2 top, and the dust absorption passage arranged in handle 3 and wiping shell 2 inner space; Described handle 3 is provided with the dust exhaust apparatus 5 being communicated with dust absorption passage; Described wiping shell 2 the latter half embeds the cavity of rub body 1; Dust storage chamber 4 is also provided with in the cavity of described rub body 1; The card base 6 that described wiping shell 2 lower end is arranged and draw-in groove 10 buckle on rub body 1; Described card base 6 is connected with the button 7 on handle 3 by extension spring.
It should be noted that, the convex structure of inverted triangle is arranged in preferred card base 6 lower end, the draw-in groove that rub body 1 matches with card base 6 10 inverted triangle shape grooves.Engaging is firmly, reliable and stable.
Wherein, described rub body 1 comprises the wiping layer 9 of wiping board 8 and the setting of wiping board 8 bottom.Wiping board 8 there are some through holes as air suction opening, dust can be adsorbed in dust storage chamber 4 from these air suction openings to be assembled, usually, can also arrange in dust storage chamber 4 and fill alarm sensor, when dust in dust storage chamber 4 stores the rub body 1 user can being pointed out more to renew completely.
Wherein, described wiping layer 9 is nylon bristle or layer of cloth with holes.
Wherein, described dust exhaust apparatus 5 comprises motor, fan and power supply.
Wherein, described handle 3 is provided with anti-slip veins 11.Grip more firm, not easily slippage, safe and reliable.
Wherein, described handle 3 is in inverse u shape structure.Be convenient to hold, control card base 6 and to pack up and the button 7 that loosens is arranged on the upside of handle 3, can operate easily, control card base 6 and engage with draw-in groove 10.
When dust accumulation is more, dismounting button can be pressed, rub body be departed from and wipes shell, the rub body more renewed, wait and gathered by the unified collection cleaning of educational administration rear service personnel the rub body having dust after class, clear up, avoid and pollute classroom environment.
The foregoing is only the preferred embodiment of the invention; not in order to limit the invention; within all spirit in the invention and principle, any amendment done, equivalent replacement, improvement etc., within the protection domain that all should be included in the invention.
