Abstract
An electrostatic dust collection blackboard comprises a blackboard body (1) and a blackboard brush (2). The electrostatic dust collection blackboard is characterized in that an induced draft fan (4) is installed on the reverse side of the blackboard body (1), an air inlet of the induced draft fan (4) is connected with one end of a flexible telescopic pipe (3), the other end of the flexible telescopic pipe (3) is connected with the blackboard brush (2), an air outlet of the induced draft fan (4) is communicated with an inner cavity of an electrostatic dust collector (5), a dust deposition cavity (6) is formed in the bottom of the electrostatic dust collector (5), and a control circuit (7) arranged on the reverse side of the blackboard body (1) is connected with the induced draft fan (4) and the electrostatic dust collector (5). Dust is made to be electrified by the electrostatic dust collector under the effect of a boosting transformer and quickly deposited in the dust deposition cavity, meanwhile, external dust can be continuously sucked into the electrostatic dust collector through the induced draft fan, blackboard cleaning and dust collection are achieved at the same time, and therefore the dust collection effect of the blackboard is well achieved, and certain popularization and use prospect is achieved.
Description
Technical field
The utility model relates to a kind of blackboard, relates in particular to a kind of electrostatic precipitation blackboard, belongs to realia technical field.
Background technology
Existing blackboard can produce a lot of airborne dust in wiping process, flies upward everywhere, can cause certain harm to teachers and students healthy for a long time, and two lack a kind of device that can realize dust suction or comprehensive dedusting in the time erasing the board always.For example Chinese patent notification number is: CN2785874Y, within open day, be: the utility model patent on June 7th, 2006 discloses a kind of magnetic dust-eliminating blackboard, it is the magnetic dust-eliminating blackboard body that three-decker is housed in a rectangular framework, upper strata is magnet board face, middle level is infill panel, lower floor is for protecting dirt sealing plate, the magnet board back side and infill panel are pasted integral shape, and on this plate face, be provided with line-spacing and evenly become the dust suction small sircle hole of linear, infill panel with protect dirt plate certain space that is separated by, this space is connecting the uniform dust suction arm of spacing below, this arm is connected with dust suction supervisor again, on dust suction supervisor, connecting the dedusting pond and the dust catcher that are filled with water.But this apparatus structure complexity, fault rate is high, and it is not too convenient to use, and dust removing effects is not good.
Summary of the invention
The purpose of this utility model is simple for existing blackboard structure, in the time erasing the board, can produce more airborne dust, do not there is dust removing effects, use defect and deficiency not too easily, now provide a kind of rational in infrastructure, when erasing the board, realized dedusting, good dedusting effect, is used a kind of electrostatic precipitation blackboard very easily.
For achieving the above object, technical solution of the present utility model is: a kind of electrostatic precipitation blackboard, comprise blackboard body and blackboard hairbrush, it is characterized in that: the back side of described blackboard body is provided with induced-draught fan, the air inlet of induced-draught fan is connected with one end of flexible telescopic tube, the other end of flexible telescopic tube is connected with blackboard hairbrush, the air outlet of induced-draught fan and the intracavity inter-connection of electrostatic precipitator, the bottom of electrostatic precipitator is provided with dust deposit chamber, the control circuit that the blackboard body back side arranges is connected with electrostatic precipitator with induced-draught fan respectively, electrostatic precipitator is connected with step-up transformer by wire.
In described blackboard hairbrush, be provided with motor, on the output shaft of motor, be fixed with brush plate or brush tube.
On the sidewall of described electrostatic precipitator, be evenly provided with air outlet, the inner side of air outlet is provided with airstrainer.
The beneficial effects of the utility model are: the utility model makes dust charged and be deposited on rapidly in dust deposit chamber under the effect of step-up transformer by electrostatic precipitator, induced-draught fan can constantly be drawn into extraneous dust in electrostatic precipitator simultaneously, rational in infrastructure, when erasing the board, realize dedusting, reach good blackboard dust removing effects, there is certain prospect of promoting the use of.
