Description
Technical field
The utility model relates to a kind of realia, specifically, relate to the clean dust-free black board eraser in a kind of blackboard eraser.
Background technology
Existing blackboard eraser is generally simple flannelette and adds sponge and main body standing part composition, causes a large amount of airborne dusts when erasing the board, the people erased the board and be sitting in front-seat classmate and all can be affected, and long-term to suck airborne dust very large for the harm of human body.
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 a kind of design science, absorbs that chalk dust ability is strong, airborne dust is few, the clean dust-free black board eraser of environment protection health.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of clean dust-free black board eraser, comprise cavity, be arranged on the motor in described cavity, drive the battery of this motor, the ring-type blackboard eraser fine hair band arranged by this motor-driven blower fan and outstanding described cavity oral area, the sidewall of described cavity arranges dividing plate, space between this dividing plate and described cavity forms chalk dust apotheca, the ash inlet of this chalk dust apotheca is located at described cavity the inner, the bottom hinged platen of described cavity, the spring always ordering about chalk dust apotheca ash inlet described in described pressing plate capping is installed between the bottom of described pressing plate and described cavity, described chalk dust apotheca outer end fills out envelope as air outlet by the ventilative sponge of ring-type.
Described on base, between described ring-type blackboard eraser fine hair band and described blower fan, be also provided with one deck hollow out filter disc.
Described on base, described motor and described dividing plate are fixed, and it is inner that described blower fan is located at described cavity, and described cavity outer end is located at by described battery, and described ring-type blackboard eraser fine hair band is fixed with described motor and described battery respectively.
Described on base, described cavity is circular cylindrical cavity, and described dividing plate is annular dividing plate, and described chalk dust apotheca is ring-type apotheca.
Described on base, the spacing of described chalk dust apotheca increases to the inner gradually from outer end.
The utility model hinge structure has substantive distinguishing features and progress, specifically, the utility model arranges cavity, mounted motor in cavity, blower fan, the blackboard eraser fine hair band of ring-type and chalk dust apotheca, operation principle is, after erasing the board, form airborne dust, owing to being cavity design, and cavity setting given prominence to by the blackboard eraser fine hair band of ring-type, form frame structure, airborne dust is easy to be inhaled in cavity under the effect of blower fan, simultaneously, due to the impact of wind-force, cover plate is blown open, airborne dust enters chalk dust apotheca, gas is appeared by ventilative sponge, chalk dust due to its particle larger, be attracted on ventilative sponge, complete the cell-phone function of chalk dust, but for improving the efficient work of chalk dust apotheca, need regular chalk dust apotheca is cleaned.
Further, between blackboard eraser fine hair band and described blower fan, install hollow out filter disc, one is to strengthen overall firmness, and two is the air-flow with chalk dust can be broken up, more easily flow into chalk dust apotheca, bounce-back after on cavity bottom can not be run into and form convection current.
Further, blower fan is located at inner terminal, and outermost end is located at by ring-type blackboard eraser fine hair band, and centre is located at by motor and battery, and layout is more reasonable.
Further, entirety is all designed to cylindrical structural, parts all adopt circulus, and space availability ratio is higher, and moulding is more attractive in appearance.
Further, the spacing of chalk dust apotheca is widened to the inner gradually from outer end, and object is stronger in order to inhale grey ability, and the ash of absorption is more.
It has design science, absorption chalk dust ability is strong, airborne dust is few, the advantage of environment protection health.
Accompanying drawing explanation
Fig. 1 is one of structural representation of clean dust-free black board eraser in the utility model.
Fig. 2 is the structural representation two of clean dust-free black board eraser in the utility model.
In figure: 1. cavity; 2. motor; 3. battery; 4. blower fan; 5. ring-type blackboard eraser fine hair band; 6. dividing plate; 7. chalk dust apotheca; 8. pressing plate; 9. ventilative sponge; 10. hollow out filter disc.
Detailed description of the invention
Below by detailed description of the invention, the technical solution of the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of clean dust-free black board eraser, comprise columniform cavity 1, the motor 2 be arranged in described cavity 1, the ring-type blackboard eraser fine hair band 5 that drives the battery 3 of this motor 2, the blower fan 4 driven by this motor 2 and outstanding 1, described cavity mouth to arrange, the sidewall of described cavity 1 arranges the dividing plate 6 of annular, space between this dividing plate 6 and described cavity 1 forms the chalk dust apotheca 7 of ring-type, the spacing of described chalk dust apotheca 7 increases to the inner gradually from outer end, object is to expand storage area, can store more chalk dust.
The ash inlet of this chalk dust apotheca 7 is located at described cavity 1 the inner, the bottom hinged platen 8 of described cavity 1, install the spring always ordering about chalk dust apotheca 7 ash inlet described in the capping of described pressing plate 8 between described pressing plate 8 and the bottom of described cavity 1, described chalk dust apotheca 7 outer end fills out envelope as air outlet by the ventilative sponge 9 of ring-type.
One deck hollow out filter disc 10 is also provided with between described ring-type blackboard eraser fine hair band 5 and described blower fan 4, described motor 2 is fixed by this hollow out filter disc 10 with described dividing plate 6, it is inner that described blower fan 4 is located at described cavity 1, described cavity 1 outer end is located at by described battery 3, described ring-type blackboard eraser fine hair band 5 is fixed with described motor 2 and described battery 3 respectively, chalk dust, by after hollow out filter disc 10, is broken up large dust air-flow, is avoided dust air-flow and body of wall base plate to liquidate and cause dust to overflow.
The course of work: hand-held blackboard eraser, opens motor 2, uses ring-type blackboard eraser fine hair band 5 to erase the board, under frame structure, airborne dust is easy to be sucked in cavity by blower fan 4, simultaneously, due to wind-force effect, pressing plate 8 is left by wind, and airborne dust enters in chalk dust apotheca 7, wind appears from ventilative sponge 9, and airborne dust is comparatively large due to particle, is stopped by ventilative sponge, absorption, stays in chalk dust apotheca 7, after closedown, motor 2 stops operating, pressing plate 8 automatic pick under the action of the spring.
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.
