Description
Technical field
The utility model relates to a kind of blackboard eraser, particularly, relates to a kind of electric blackboard eraser.
Background technology
Blackboard eraser is the instrument of classroom instruction indispensability.In prior art, blackboard eraser has many shortcoming, and one is because be difficult to wipe clear blackboard after the cotton of blackboard eraser occupies dust, reduces the definition of writing on the blackboard.Two is that after occupying dust because of blackboard eraser on cotton, when erasing the board, dust wafts everywhere, has bad impact to student and teacher, and especially teacher is in this environment for a long time, and dust extremely easily damages throat and lung.
In existing novel blackboard eraser, have water injection type blackboard eraser, although water dust suction, power is little does not have water not dust suction, and power flood overflows, and blackboard is very easily reflective and be not easy to write letter written with chalk under the effect of water.Although portable electric blackboard eraser volume is little portable, due to small size, component is inadequate, dust cannot be stoped to enter motor, make motor damage, and the life-span is low and want diligent charging.Batching formula blackboard eraser improves cleaning capacity by constantly changing cloth, but will replace yardage roll always, loaded down with trivial details and sustainability is low.
Utility model content
In order to solve the defect and deficiency that exist in prior art, the utility model provides a kind of blackboard eraser, has lasting dust removal ability, good sustainability and property easy to clean.
Described can dust suction electric blackboard eraser, by blackboard eraser, preparation device, the large component composition of disposal box three.Described blackboard eraser is by Miniature low voltage motor, and hairbrush, ultrasonic transmitter, suction port, gas flow tube, air inlet, hand switch and automatic switch form.Described preparation device comprises electromagnetic switch, automatic hose reel.Described dust arrester is by dust pocket, and blower fan, motor, conical screen and cylinder screen form.Hand switch is opened at ordinary times, automatic switch triggers automatically when taking, when blackboard eraser works by dust under ultrasonic wave and hairbrush brush, there is provided powerful negative pressure by blower fan and produce air-flow and take away dust, dust by gas flow tube in disposal box by conical screen and cylinder screen, under cyclogenesis, be deposited to dust pocket.
Described ultrasonic transmitter quantity is two, the main coverage covering blackboard eraser, by launching ultrasonic wave, dust is more easily come off.
Described hairbrush one end is connected with gear by axostylus axostyle, and gear is linked by chain and Miniature low voltage motor gear.
The space of described gear and hairbrush is provided with dividing plate, to avoid dust nuisance Miniature low voltage motor.
Described automatic switch is made up of the permanent magnet to attract each other for a pair and link; At ordinary times owing to hanging, blackboard eraser deadweight is greater than magnetic force, makes circuit breaker; Take off in use, due to the adhesive of magneticaction permanent magnet, circuit ON, blackboard eraser work.
Described hand switch is cleaned at regular intervals hairbrush for the convenience of the users.
Described air inlet makes air-flow pass through to take away dust, avoids airflow to blow bad writing on the blackboard.
Described electromagnetic switch is made up of electromagnet and thin iron block, and thin iron block blocks gas flow tube at ordinary times, stops air-flow; When the blackboard eraser work that this electromagnet is served, the energising of this electromagnet produces magnetic force, picks up thin iron block, makes gas flow tube to pass through air-flow; This switch avoids another block blackboard eraser air-breathing when use one piece of blackboard eraser.
Described automatic hose reel is dominated by clockwork spring, can pull out gas flow tube in use, because the effect of clockwork spring makes gas flow tube be pulled when not using, does not allow the sagging obstruction teachers ' teaching of pipeline.
Described dust pocket is blocked by plastics barb, can be taken off and pour out dust, cleaning dust pocket by rotation knob.
Described conical screen is to produce spiral cyclone, makes ash fall in dust pocket.
Described blower fan rotates and produces huge negative pressure, causes high velocity air.
Described motor skin has HEPA dirt filtrating screen, and protection motor does not damage by dust.
The beneficial effects of the utility model are: adopt electric dust absorption, make a large amount of dust all be inhaled into disposal box, effectively contained the loss of dust, be conducive to the working healthily of teacher, only need the dust in disposal box to outwell when daily cleaning, very easily clean.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
In figure: 1-Miniature low voltage motor, 2-ultrasonic transmitter, 3-gear, 4-dividing plate, 5-gas flow tube, 6-permanent magnet, 7-air inlet, 8-suction port, 9-hairbrush, 10-chain, 11-link, 12-hand switch, 13-automatic hose reel, 14-electromagnet, the thin iron block of 15-, 16-cylinder screen, 17-conical screen, 18-knob, 19-blower fan, 20-motor, 21-HEPA dirt filtrating screen, 22-barb, 23-dust pocket, 24-automatic switch, 25-power supply.
As shown in the figure, one can dust suction electric blackboard eraser, and by blackboard eraser, preparation device, disposal box three great institutions forms.Wherein blackboard eraser is by Miniature low voltage motor 1, hairbrush 9, ultrasonic transmitter 2, suction port 8, gas flow tube 5, air inlet 7, and hand switch 12 and automatic switch 24 form, and is hung place by link 11.Hand switch 12 is in opening time flat, needs to close when cleaning hairbrush 9 again.Automatic switch 24 is made up of permanent magnet 6 and 11 link, and the irony thing on link 11 can be attracted by permanent magnet 6, and when hanging at ordinary times, magnetic force is less than overall gravity, so do not contact each other, and down circuitry.Hairbrush 9 one end is connected with gear 3 by axostylus axostyle, and gear 3 is by chain 10 and Miniature low voltage motor 1 gear-linked.Gear 3 is provided with dividing plate 4 with the space of hairbrush 9.
During work, take off blackboard eraser, contact, circuit ON under magneticaction, blackboard eraser carries out work.Two ultrasonic transmitters 2 cover blackboard eraser wiped area, make letter written with chalk be easy to drop by ul-trasonic irradiation.Hairbrush 9 is under the effect of Miniature low voltage motor 1, by the conducting power work of gear 3 and chain 10, swipe letter written with chalk, make it before suction port 8, form a large amount of dust that floats, the high velocity air caused by air inlet 7 is taken away by suction port 8, enters gas flow tube 5.
Preparation device is made up of component 13-15, and store a large amount of gas flow tube 5 in automatic hose reel 13, the used time does not roll up at ordinary times, can easily pull out during use, makes the automatic recovery of gas flow tube 5 after using under the effect of clockwork spring.The switch of gas flow tube 5 together with electromagnet 14 forms with thin iron block 15; When served blackboard eraser does not use, electromagnet 14 no power, without magnetic force, makes thin iron block 15 block the air motion of gas flow tube 5, avoids another blackboard eraser air-breathing when a blackboard eraser works; In use, electromagnet 14 energising produces magnetic force and attracts thin iron block 15, makes gas flow tube 5 to pass through air-flow.
Disposal box forms primarily of component 16-23, motor 20 and blower fan 19 produce huge air negative pressure, high-speed air is caused to flow, cylinder screen 16 and conical screen 17 make air-flow form cyclone, by the effect of centrifugal force by dust settling in dust pocket 23, remaining air-flow is gone out by HEPA dirt filtrating screen 21, and dust pocket 23 is hung up by barb 22, rotates knob 18 and takes off and can carry out cleaning inside.
