The defects such as the present invention provides a kind of electric dust absorption blackboard eraser for solving the problems of the technologies described above, and solves the operation inconvenience of existing electric blackboard eraser, expensive, this electric dust absorption blackboard eraser, has detachable, easy to use, multiple functional, the advantages such as result of use is good.
The present invention is the technical scheme that the deficiency solved the problems of the technologies described above adopts: electric dust absorption blackboard eraser, be provided with housing, the bottom surface of housing is provided with bleeding point, multiple suction powder hole, magnetic switch and many pads, suction box is provided with in housing, dust exhaust apparatus is provided with in suction box, dust exhaust apparatus is arranged on bleeding point and inhales powder hole place, described dust exhaust apparatus is made up of power supply, motor, blade, power supply is connected to feeding electric motors with motor, supply line between power supply and motor is provided with magnetic switch, and the driving shaft of motor is connected with blade.
Be provided with dust storage box in housing of the present invention, dust storage box is communicated with suction box.
Be provided with dust collection bag in dust storage box of the present invention, the sack of dust collection bag is communicated with suction box.
Housing of the present invention is provided with storage box case lid, is dust storage box below storage box case lid.
Storage box case lid of the present invention is provided with gas outlet.
The medial surface of storage box case lid of the present invention is provided with filter course, and filter course is corresponding with gas outlet to be arranged.
Power supply of the present invention is also connected with time display, and time display is arranged on housing.
Dust storage box of the present invention is low setting after front height, and its height is reduced backward gradually by suction box direction.
Beneficial effect of the present invention is:
1, on housing bottom surface, arrange multiple air suction opening, increase air suction opening quantity, dust suction face is large, increases the chance that dust is sucked into the space of inner casing, promotes the effect of dust suction.
2, with the addition of electromagnetic switch, automatically can open dust exhaust apparatus, auto power off when leaving when blackboard eraser contacts baseplate blackboard, not only convenient, fast, power saving, also eliminates teachers and students repeatedly by the worry of switch.
3, built-in time display, at blackboard eraser surface displaying time, can allow teacher better hold the time, increases work efficiency.
4, wiping blackboard structure is reasonable, easy to use, electric dust absorption blackboard eraser to the absorptivity of dust up to more than 96%.
5, dust collection bag is demountable structure, and dust can be accumulated, and after dust collection bag cleans out, again can be recovered utilization.

Detailed description of the invention
As shown in the figure, electric dust absorption blackboard eraser, be provided with housing 1, the bottom surface of housing 1 is provided with bleeding point 2, multiple suction powder hole 3, magnetic switch 4 and many pads 5, in housing 1, is provided with suction box 6, suction box 6 and bleeding point 2 with inhale powder hole 3 and be communicated with, dust exhaust apparatus 7 is provided with in suction box 6, dust exhaust apparatus 7 is arranged on bleeding point 2 place, and dust is sucked suction box 6 by bleeding point 2 and suction powder hole 3 by dust exhaust apparatus 7, and dust exhaust apparatus 7 carries out switch control rule by magnetic switch 4.
Be provided with dust storage box 8 in described housing 1, dust storage box 8 is communicated with suction box 6, and the dust sucking suction box 6 enters dust storage box 8 and stores.
Be provided with dust collection bag 9 in described dust storage box 8, the sack of dust collection bag 9 is communicated with suction box 6, and dust collection bag 9 pairs of dust are collected, and conveniently clears up blackboard eraser.
Described housing 1 is provided with storage box case lid 10, is dust storage box 8, utilizes storage box case lid below storage box case lid 10, conveniently clears up dust storage box, facilitates simultaneously and changes dust collection bag 9 and clear up.
Described storage box case lid 10 is provided with gas outlet 11, ventilates smooth and easy, improves the dust collection efficiency of dust exhaust apparatus.
The medial surface of described storage box case lid 10 is provided with filter course 12, and filter course 12 is corresponding with gas outlet 11 to be arranged, and prevents dust from flying out from gas outlet, filters the air in dust storage box.
Described dust exhaust apparatus 7 is made up of power supply, motor, blade, and power supply is connected with motor with magnetic switch 4, and the driving shaft of motor is connected with blade.
Described power supply is also connected with time display 13, and time display 13 is arranged on housing 1, can displaying time and date.
Motor driven vane High Rotation Speed, air is discharged at a high speed, and the air of vane nose vacuum part constantly supplements the air in blower fan, make dust suction inside produce instantaneous vacuum, form Negative Pressure Difference with external atmosphere pressure, under this differential pressure action, suck the air containing dust, leach dust through filter course, the larger Negative Pressure Difference of air quantity is larger, then dust removal ability is also stronger.Described dust storage box is low setting after front height, and its height is reduced backward gradually by suction box direction.This kind of set-up mode makes stepped generation negative pressure in dust storage box, makes lower than in suction box of the air pressure in dust storage box, is collected into rapidly in dust collecting box by the dust that suction box sucks.
This device have employed magnetic switch to control the open and close of dust exhaust apparatus, because the educational institution of more than 95% all be band magnetic blackboard, this switch has been installed, not only reduce power consumption and eliminate the worry that teacher wants on-off switch at every turn, the rechargeable lithium battary of this device simultaneously, compared with dry cell, long service life, decrease the wasting of resources, decrease environmental pollution simultaneously.The chassis of this device is also the bright spot of this device simultaneously, traditional strip breach dust suction has been broken in its design, although strip easily inspiration, but control range is little, when blackboard wiping, pick-up performance is not obviously best, and this device have employed the poroid design of symmetric form, the drawback improving same device on market of comprehensive and reasonable, makes pick-up performance obtain new breakthrough more.
