Description
Technical field
The utility model relates to a kind of blackboard eraser, specifically, relate to a kind of dust-proof blackboard eraser.
Background technology
Blackboard right and wrong educational aid usually, teacher by writing the content of courses to reach the object of education student on blackboard with chalk.But student is when erasing the board, can produce a large amount of chalk dusts, a large amount of chalk dust waves contaminated environment and descending slowly and lightly on the body of teacher, student, the clothing and be exposed to outer hair, skin made dirty.The chalk dust entering air can impact the breathing of academics and students again, and the problem of waving how reducing chalk dust is people's problem demanding prompt solutions.
In order to solve above Problems existing, people are seeking a kind of desirable technical solution always.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, thus provides the dust-proof blackboard eraser of a kind of design science, rational in infrastructure, practical, easy to use and good dustproof effect.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of dust-proof blackboard eraser, it comprises housing and is arranged on the sponge rub body of described housing side, the corresponding described sponge rub body of described housing is provided with dust-proof cover body, described housing side offers air suction opening, and it is inner that described air suction opening is arranged on described dust-proof cover body, the power supply being provided with motor in described housing and being connected with described motor, the output shaft of described motor is provided with fan, and described housing offers dust removal port.
Based on above-mentioned, the outward flange of described dust-proof cover body is curved edge, and described curved edge place is provided with sponge block.
Based on above-mentioned, offer dust suction groove in the middle part of described sponge rub body, the corresponding described dust suction groove of described housing offers auxiliary air suction opening.
Based on above-mentioned, in described housing, be provided with magnet.
Based on above-mentioned, the external end of described sponge brush is curved end.
Based on above-mentioned, described housing is provided with switch, described switch is arranged between described motor and described power supply.
The utility model hinge structure has substantive distinguishing features and progress, specifically, the utility model comprises housing and sponge rub body, described housing is provided with dust-proof cover body, the chalk dust produced that erases the board enters dust-proof cover body, is provided with motor in described housing, and this motor can drive fan to produce negative pressure, by air suction opening, chalk dust suction casing is inner, reduce the pollution of chalk dust; It has the advantage of design science, rational in infrastructure, practical, easy to use and good dustproof effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment 1 in the utility model.
Fig. 2 is the structural representation of embodiment 2 in the utility model.
Detailed description of the invention
Below by detailed description of the invention, the technical solution of the utility model is described in further detail.
embodiment 1
As shown in Figure 1, a kind of dust-proof blackboard eraser, it comprises housing 1 and is arranged on the sponge rub body 2 of described housing 1 side, blackboard eraser main body is formed with this, the corresponding described sponge rub body 2 of housing 1 described in the present embodiment is provided with dust-proof cover body 3, described dust-proof cover body 3 wraps up described sponge rub body 2 and arranges, and makes the chalk dust wiped enter dust-proof cover body 3 and prevents chalk dust from flying upward; Described housing 1 side offers air suction opening 11, it is inner that described air suction opening 11 is arranged on described dust-proof cover body 3, the power supply 6 being provided with motor 4 in described housing 1 and being connected with described motor 4, the output shaft of described motor 4 is provided with fan 5, and described housing 1 offers dust removal port; Described motor 4 drives described fan 5 to rotate and then makes to form subnormal ambient in housing 1, can suck chalk dust by air suction opening 11.Described housing 1 is provided with switch, and described switch is arranged between described motor 4 and described power supply 6; Open as required or disable motor 4.
When this dust-proof blackboard eraser erases the board, the chalk dust of erasing can enter dust-proof cover body 3, and then avoid that chalk dust four is loose to fly upward, simultaneously the generation negative pressure of described motor 4 and described fan 5 in described housing 1, by chalk dust by air suction opening 11 suction casing 1, reduces the pollution of chalk dust.
In order to make dust cover body to fit tightly with blackboard and not damage blackboard, the outward flange of described dust-proof cover body 3 is curved edge, and described curved edge place is provided with sponge block, dust-proof cover body 3 is contacted with blackboard closely and prevents scratch blackboard for soft contact.
For the ease of placing whole dust-proof blackboard eraser, in described housing 1, be provided with magnet, not the used time by magnet adsorption on blackboard.
embodiment 2
The difference of the present embodiment and embodiment 1 is: as shown in Figure 2, dust suction groove 7 is offered in the middle part of described sponge rub body 2, the corresponding described dust suction groove 7 of described housing 1 offers auxiliary air suction opening 12, in the present embodiment, sponge rub body 2 is divided into two pieces, the outer end of every block sponge rub body 2 is curved end simultaneously, and the chalk dust that erasing blackboard is produced thoroughly can enter dust-proof cover body 3.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the field have been to be understood that: still can modify to detailed description of the invention of the present utility model or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope of the utility model request protection.
