Abstract
The utility model discloses a rechargeable dust-absorption chalk brush, and belongs to the field of education supplies. The rechargeable dust-absorption chalk brush comprises a shell, bristles, a miniature dust collector, a storage battery, a dust collection box, a capacitor piece, and a switch. The bristles are arranged on the lower side of the straight-panel capacitor piece; when the chalk brush is used, one part of dust is directly absorbed by the miniature dust collector, and the other part of the dust is adsorbed to the outer surface of the straight-panel capacitor piece, is carried into dust absorption holes by air flow produced by the miniature dust collector, and absorbed by the miniature dust collector, so the defects caused by insufficiency of absorption force in the conventional products of the same kind are overcome; the rechargeable dust-absorption chalk brush effectively prevents dust from being scattered, and the quality of air in a classroom is guaranteed, so the body health of teachers and students is protected; and a product is low in manufacturing cost, has a wide application range, and is easy to popularize.
Description
Technical field
The utility model relates to a kind of blackboard eraser, belongs to educational aid articles for use field.
Background technology
In present realia; Blackboard, chalk and eraser are basic realias; In order to reduce the dust that produces because of erasing the board to teachers and students' health affected; Clear dust-free chalk of people's phase supervention and dust-collecting eraser, but the former improves DeGrain, and the latter causes pick-up performance unsatisfactory because of the suction deficiency.
Summary of the invention
The purpose of the utility model is the rechargeable type dust-collecting eraser that provides a kind of dedusting pick-up performance good.
Technical solution
The utility model comprises: eraser, have the hole on the hair brushing plate of eraser, and be provided with curved slab in the eraser cavity, air suction opening is established in the curved slab center; Curved slab is provided with battery, micro-cleaner, and eraser cavity top is provided with dust-collecting box; The dust-collecting box base plate is provided with dust export, and micro-cleaner dust suction end is connected with air suction opening, and micro-cleaner dust discharge end is connected with dust export; Two upper lateral parts of dust-collecting box are provided with airway, in airway, are provided with screen pack, and the airway exit is positioned at the bristle place; The eraser outside is equipped with switch, and switch is connected with battery, and battery is connected with micro-cleaner.
Said curved slab is a capacitance sheet.
Said dust-collecting box and eraser cavity are pegged graft.
The said eraser outside is provided with plug, and plug is connected with battery.
This novel practical device has following characteristics
1, this novel practical bottom of device is equipped with capacitance sheet, can produce static, and the dust that can produce when erasing the board through static has attracted, thereby avoids dust disorderly to fly.
2, breather pipe is equipped with in this novel practical crust of the device inboard, when the air-flow process breather pipe that is produced by micro-cleaner, discharges near the bristle, and the air-flow of discharge can be blown in the air suction opening being adsorbed on the lip-deep dust of capacitance sheet.Thereby it strengthens pick-up performance.
3, this novel practical device case outside is equipped with plug, and installed inside has battery, can directly charge in the classroom, and is comparatively convenient.

The specific embodiment
Have hole 15 on the hair brushing plate 10 of the utility model eraser, be provided with curved slab 11 in the eraser cavity 13, curved slab 11 capacitance sheets; Air suction opening 6 is established in the curved slab center, and curved slab 11 is provided with battery 4, micro-cleaner 8; Eraser cavity 13 tops are provided with dust-collecting box 5, and dust-collecting box 5 base plates are provided with dust export 7, and micro-cleaner 8 dust suction ends are connected with air suction opening 6; Micro-cleaner 8 dust discharge ends are connected with dust export 7, and two upper lateral parts of dust-collecting box 5 are provided with airway 2, in airway 2, are provided with screen pack 3; The airway exit is positioned at hair brushing plate 10 places; The eraser outside is equipped with switch 1, and switch 1 is connected with battery 4, and battery 4 is connected with micro-cleaner 8.Dust-collecting box 5 is pegged graft with eraser cavity 13, and the eraser outside 12 is provided with plug 14, and plug 14 is connected with battery 4.
During use: when electric weight in the battery 4 is sufficient; When should novel rechargeable type dust-collecting eraser on blackboard, wiping, the dust of generation enters in the eraser cavity 13 through the hole 15 on the hair brushing plate 10; Part dust is absorbed by micro-cleaner 8; Another part then is adsorbed on the outer surface of capacitor 11, and the dust that the air-flow that micro-cleaner 8 produces will be adsorbed on capacitor 11 outer surfaces is brought in the air suction opening 6, thereby dust is absorbed by micro-cleaner 8; Dust just can be discharged in the dust-collecting box 5; The airway that is positioned at bristle 10 places enters into eraser cavity 13 with the dust on the hair brushing plate 10 through hole 15, and the dust that is produced is all entered in the brush cavity 13, has avoided flying upward of dust.After using a period of time, can dust-collecting box 5 wherein be transferred to from eraser cavity 13, in dust importing dustbin wherein.After using a period of time, during this novel rechargeable type dust-collecting eraser power shortage, take out its built-in plug 14, insert socket and charge.Charging just can be used after accomplishing again.
